Objective   To compare the efficacy of three different surgical methods in the treatment of common bile duct stones after cholecystectomy:open common bile duct exploration (OCBDE),endoscopic retrograde cholangiopancreatography and papillary sphincterotomy (ERCP/EST),and laparoscopic common bile duct exploration (LCBDE). Methods   The clinical data of 109 cases of recurrent choledocholithiasis after cholecystectomy treated in our hospital from July 2016 to July 2020 were analyzed retrospectively.Among them,33 cases were ERCP,40 cases were OCBDE group,and 36 cases were LCBDE.The influence of confounding factors among the groups was balanced by the tendentious score matching method (PSM),and the clinical efficacy and complications of the three groups after matching were compared.  Results   28 patients were included in each group by PSM method,and the baseline data of the three groups were not statistically significant(P>0.05).No statistical difference was found in the success rate of operation and stone clearance rate among three groups (P>0.05).The specific amount of bleeding,specific duration of operation,specific duration of anal exhaust and specific duration of hospitalization after operation in ERCP group were lower/shorter than those in OCBSE group and LCBDE group,with obvious difference (P<0.05),while the specific amount of bleeding,specific duration of operation,specific duration of anal exhaust and specific duration of hospitalization after operation in LCBDE group were lower/shorter than those in OCBSE group,with obvious difference (P<0.05).The incidence rate of perioperative complications of ERCP group showed no obvious difference with that of other 2 groups (P>0.05),while the incidence rate of postoperative complications in LCBDE group was lower than that in OCBDE group,with statistical difference (P<0.05).Postoperative follow-up showed that the recurrence rate of common bile duct stones in ERCP group was higher than OCBDE and LCBDE groups,with statistical difference (P<0.05),while the recurrence rate yielded no statistical difference between OCBDE group and LCBDE group (P>0.05). Conclusion   ERCP,OCBDE and LCBDE can effectively remove common bile duct stones after gallbladder surgery.ERCP surgery is less traumatic,but it is prone to severe complications such as acute pancreatitis and hyperamylasemia after surgery,and the residual rate of stones after surgery is high.LCBDE has the advantage of micro-invasive surgery than OCBDE,but it is not suitable for patients with severe abdominal adhesion.It is recommended that the operator select an appropriate surgical method according to the specific situation of the patient.

Objective To investigate the regulatory effect of leucine-rich-alpha2-glycoprotein 1(LRG1) on the proliferation,migration and invasion of non-small cell lung cancer(NSCLC) cellsvia the Runt-related transcription factor 1(RUNX1)/osteopontin(OPN) axis. Methods To determin the expression of LRG1,RUNX1 and OPN in cultured human type II alveolar epithelial cells and human NSCLC cell lines A549,NCI-H838 and NCI-H1650.The human NSCLC cell line A549 cultured in vitro was randomly divided into control group,LRG1 knockdown group,negative control group,RUNX1 overexpression group,LRG1 knockdown + RUNX1 overexpression group by random number table method,after cells were grouped and transfected with plasmids,to detect the proliferation,apoptosis,migration,invasion,the expression of apoptosis proteins(Bcl-2,caspase-3,Bax) and epithelial-mesenchymal transition marker proteins(N-cadherin,E-cadherin),the expressions of LRG1,RUNX1 and OPN in A549 cells in each group.〖WTHZ〗Results Compared with human type II alveolar epithelial cells,the mRNA and protein expressions of LRG1,RUNX1 and OPN in human NSCLC cell lines A549,NCI-H838 and NCI-H1650 higher(P<0.05).Compared with the control group,the positive rate of EdU,the migration rate,the number of invasion,the mRNA and protein expressions of LRG1,RUNX1 and OPN,and the protein expression of Bcl-2 and N-cadherin in the LRG1 knockdown group were decreased(P<0.05),and the apoptosis rate and the protein expression of caspase-3,Bax,and E-cadherin were increased(P<0.05);The changes of various indicators in RUNX1 overexpression group were contrary to those in LRG1 knockdown group,and the overexpression of RUNX1 could reverse the effects of LRG1 knockdown on various indicators of cells.Conclusion Knockdown of LRG1 can inhibit the proliferation,migration and invasion of NSCLC cells and promote their apoptosis by down-regulating the expressions of RUNX1 and OPN.

Cholangiocarcinoma is a malignant tumor originating from the epithelium of the bile ducts,and its incidence is increasing year by year,especially intrahepatic bile duct carcinoma that originates from the bile duct branches above the second level in the liver.Due to the insidious early symptoms and the lack of effective screening methods,most patients have lost the opportunity for radical surgery by the time they present.Over the past few years,several drugs have been developed that target genetic alterations with the detection of the cholangiocarcinoma genome.The molecular targets with clinical significance mainly include fibroblast growth factor receptor(FGFR),isocitric acid dehydrogenase(IDH),RAS-RAF-MEK-ERK,ERBB,VEGF and NTRK.Drugs targeting their targets show encouraging response rates and survival data as second-line therapies,and are characterized by high specificity and low toxicity.Therefore,targeted therapy is gradually emerging in the treatment of cholangiocarcinoma.In this review,we discuss the latest advances in targeted therapies for cholangiocarcinoma.

Pancreatic cancer is a highly malignant tumor of the digestive system with poor prognosis.Due to the lack of effective early screening and diagnosis methods,the majority of patients with pancreatic cancer present with locally advanced or metastatic disease at diagnosis.For advanced pancreatic cancer,the major treatment strategy is still chemotherapy-based comprehensive treatment.The development of immunotherapy and targeted therapy gives us cause for optimism in our pursuit of better treatment.This article reviewed the advances in immunotherapy and targeted therapy of advanced pancreatic cancer.

Objective To investigate the clinical value of watershed analysis to anatomical sublobectomy in the treatment of early peripheral Non-Small-Cell Lung Carcinoma(NSCLC) characterized by Ground Glass Nodules(GGN) through fluorescence thoracoscopy. Method A total of 81 cases of early peripheral GGN-like non-small-cell lung carcinoma treated by thoracic surgery in our hospital from September 2021 to September 2022 were retrospectively studied.According to the different methods of fluorescence thoracoscopic surgery,the patients were divided into two groups.The group of anatomical sublobectomy with the watershed analysis(hereinafter,referred to as the watershed group) including 42 cases,and the anatomical pulmonary segmental resection group(hereinafter,referred to as the pulmonary segmental resection group) including 39 cases.The general surgical data,perioperative indexes and postoperative complications were compared between the two groups. Results The operations of the patients were successfully completed for both groups,without any perioperative death.For the watershed group,there were no cases that switched to thoracotomy or changed the operation style,and no cases of incision or missed incision were observed.For the pulmonary segmental resection group,there were 2 cases that changed the operation style.The surgical margin distance of the watershed group[(26.24±3.87)mm] was slightly smaller than that of the pulmonary segmental resection group[(26.62±3.32)mm].But the difference was not statistically significant(P>0.05).The amount of blood loss[32.14(20.00,50.00)ml vs 85.38(30,100)ml],operative time[(146.76±41.51)min vs (184.944±50.42)min] and postoperative drainage time[2.43(2.00,3.00)d vs 4.05(3.00,5.00)d] of the watershed group were lower than those of the pulmonary segmental resection group.And the differences were statistically significant(P<0.05).The complication rate of the watershed group(11.91%) was lower than that of the pulmonary segmental resection group(30.77%).And the difference was statistically significant(P<0.05).Totally,25 patients(64.12%) in the pulmonary segmental resection group underwent the preoperative puncture localization,but none in the watershed group.For both groups,there was no tumor recurrence during the follow-up.Conclusion The application of watershed analysis to anatomical sublobectomy in the treatment of early peripheral NSCLC by fluorescent thoracoscopy can simplify the surgical procedure,accurately remove the lesion,and ensure the curative effect of oncology.The clinical practices have proved that the approach is scientifically reasonable,safe and feasible.

Objective To investigate the treatment,clinical effect and prognosis of subdural effusion after decompressive craniectomy in patients with severe brain injury.Method A retrospective analysis was performed on the clinical data of 54 patients with severe craniocerebral injury secondary to subdural hydrops after decompression after craniectomy admitted to the First Affiliated Hospital of Xinxiang Medical College from January 2015 to December 2020.According to clinical symptoms and fluid accumulation,34 patients were treated conservatively,and 20 patients were treated surgically.3 months after treatment,head CT was re-examined to evaluate fluid absorption.After 6 months of treatment,the daily living ability of patients was assessed by the Daily Living Ability Assessment Scale(ADL).Result The effective rate was 85%(29/34) in the non-surgical group and 90%(18/20) in the surgical group.There was no significant difference in effective rate between the two groups(P>0.05).After 6 months of follow-up,the ADL score of 2 groups was higher than that of the corresponding group before treatment,and the difference was statistically significant(P<0.05). Conclusion For patients with subdural effusion after decompression after craniocerebral decompression,individualized treatment can achieve satisfactory results according to the amount of effusion and clinical symptoms.

Hepatocellular carcinoma (HCC) is a common malignant tumor.Patients often lose the opportunity for surgery because of the middle and late stage when they are diagnosed,and the prognosis is extremely poor.In recent years,anti-PD immunotherapy has made a breakthrough in the treatment of advanced liver cancer.Immunotherapy has achieved good results in some patients,but there are still many patients with poor response to immunotherapy.Therefore,there is an urgent need to find clinical or biological indicators that can be used to predict the efficacy of immunotherapy in order to maximize clinical benefits while avoiding adverse effects.This article aims to summarize the relevant indicators and potential predictive mechanisms that can be used to predict the efficacy of liver cancer immunotherapy,so as to provide help for guiding clinical treatment.

Objective  Through retrospective analysis of the case data of infusion port implantation by various approaches,tried to find out the best approach for infusion port implantation. Methods  104 patients who underwent infusion port implantation from January 2019 to December 2021 in our department were retrospectively analyzed.Including internal jugular vein approach in 55 cases (group A),subclavian vein approach in 49 cases (group B),compared the differences in operative time,puncture time,catheter length,intraoperative and postoperative complications.Results  Compared with group B,the puncture time of the group A was shorter[(8.84±3.10)min vs. (11.22±3.86)min],,less bleeding[(12.64±5.63)ml vs (15.71±7.07)ml],the incidence of catheters heterotopia was low(0 vs 8.16%,all P＜0.05).There was no significant difference in intraoperative complications such as pneumothorax and postoperative complications between the two groups（P>0.05). Conclusion  The puncture time of the internal jugular vein is shorter,the success rate is higher,and the incidence of complications such as catheter heterotopia is lower,therefore,the first choice should be the right internal jugular vein.

Prolonged Postoperative Ileus (PPOI) often occurs after abdominal surgery,and it is still one of the common complications in the field of surgery,which not only results in the prolongation of postoperative recovery time and hospital stays but also one of the main reasons for the increase of patients’ economic burden and the waste of medical resources.It has been paid more and more attention by scholars because of its special clinical manifestations and the lack of recognized treatment and preventive measures.This review intends to make a summary and prospect of the related mechanisms of PPOI,the auxiliary diagnostic methods of PPOI,and the treatment methods that show a certain curative effect on PPOI.

Objective  To reveal the expression and underlying mechanism of LINC01197 in lung adenocarcinoma(LUAD).  Methods   The expression of LINC01197 was detected by real-time fluorescence quantitative PCR(qRT-PCR),and the expression of Notch signaling molecules(Notch1 and Hes1) were detected by Western blot.Cell proliferation and invasion ability were analyzed by MTT,colony formation and Transwell assays.The effect of LINC01197 on tumor growth was examined in a xenograft tumor assay.  Results  LINC01197 was down-regulated in LUAD,and the protein levels of Notch1 and Hes1 were both up-regulated(P<0.05).Overexpression of LINC01197 inhibited LUAD cell proliferation and invasion,while knockdown of LINC01197 had the opposite effect(P<0.05).Interestingly,LINC01197-induced changes in cell behavior could be reversed by Notch1 modulators(P<0.05).Furthermore,LINC01197 overexpression inhibited tumor growth and Notch signaling in vivo(P<0.05).  Conclusion  LINC01197 can exhibit anti-proliferation and anti-invasion effects in LUAD by inhibiting Notch signaling pathway.

Objective To investigate the clinical effect of bedside fiberoptic bronchoscopy on patients with traumatic brain injury complicated with pulmonary infection undergoing mechanical ventilation. Methods From July 2018 to July 2022, 82 patients with traumatic craniocerebral injury complicated with pulmonary infection treated in our hospital were enrolled,42 patients with routine sputum aspiration were set as the control group,and 40 patients with bedside fiber bronchoscopy were set as the experimental group.Sputum samples were collected from both groups for examination and culture,and clinical data such as chest CT lesion absorption time,mechanical ventilation time,anti-infection course,ICU stay time were recorded.Driving pressure (△P),oxygenation index (OI),respiratory mechanical index and detection rate of effective pathogens were calculated.GOS-E score was followed up 6 months after injury. Results The total effective rate of the experimental group (95.00%) was higher than that of the control group (78.57%)(P<0.05).The ICU stay time,mechanical ventilation time,focus absorption time,driving pressure (△P),oxygenation index (OI),respiratory mechanics index and GOS-E score of the experimental group were significantly improved compared with the control group,and the differences were statistically significant (P<0.05). Conclusions  The implementation of bronchoscopy in ICU patients with traumatic craniocerebral injury and pulmonary infection can effectively improve pulmonary ventilation,lung dynamic compliance,and cerebral blood perfusion,which is helpful for clinical brain-lung conflict management and neurological prognosis.

Objective To detect the correlation between the clinical imaging features and the degree of invasion of pulmonary pure ground-glass nodules (pGGNs) (≤ 3cm). Methods The  clinical data of 886 patients who underwent minimally invasive surgery from June 2013 to June 2016 for pulmonary nodules were collected. Among these, 72 patients had complete clinical data and isolated pulmonary GGN resection, and the  diameter of the pulmonary GGN was ≤ 3cm.Logistic regression analysis was used to analyze the independent risk factors for invasiveness of pure ground glass  nodules. Receiver operating characteristic curve (ROC curve) was used to determine the optimal cut-off value for preinvasive and invasive lesions. Results Univariate analysis demonstrated that there were significant differences in carcinoembryonic antigen,maximum diameter,and area of pGGNs in patients with pre-invasive and invasive lesions (P<0.05).Multivariate logistic regression analysis showed that there were only statistical differences in the maximum diameter of nodule pre-invasive and invasive lesions.The optimal cut-off value for CT-maximal diameter to predict pre-invasive lesions or invasive lesions was 1.08cm. Conclusion Therefore,predicting the pathological types of nodules (pre-invasive or invasive) by measuring the maximum diameter of pGGNs is reliable,with the most reliable cut-off value as 1.08cm.

Objective   To summarize the etiology,clinical features,treatment and prevention of internal abdominal hernia after gastric surgery(Petersen hernia) and improve the understanding of Petersen hernia.  Methods   A retrospective analysis in January 2018 to December 2021 jilin university fellowship between China and Japan hospital for treatment of 9 cases after gastrectomy Petersen hernia patients,7 cases underwent open Bie-ⅱ anastomosis and 2 cases underwent Roux-en-Y anastomosis due to the primary disease.The median duration of onset was 2 days.The percentage of neutrophils in blood routine was increased to varying degrees.Preoperative abdominal CT showed anastomotic wall thickening,proximal small bowel obstruction sign 4 cases,small intestine torsion signs in 2 cases,no special signs only 3 cases of small intestinal obstruction,has not been in patients with preoperative diagnosis for Petersen hernia,all patients underwent surgical treatment,intraoperative see output section of the small intestine to shift into the Petersen clearance and hernia in 5 cases,There were 3 cases without torsional herniation into Petersen space in the output segment and 1 case with torsional herniation into Petersen space in the input segment.Among them,4 patients underwent intestinal resection and anastomosis due to intestinal necrosis.  Results   One patient developed pleural and abdominal effusion after operation,and all patients were cured and discharged after treatment.  Conclusions   Petersen’s hernia is a relatively rare complication after gastrectomy.Preoperative abdominal CT can help to determine the criticality of the patient’s condition and can be the first choice of examination.A small number of patients with acute pancreatitis should pay attention to preoperative and postoperative amylase changes,and once the diagnosis is confirmed,surgery should be performed as soon as possible.
