Objective To explore the clinical effects of applying VSD technology combined with forearm flap transplantation to repair the deep wound on the forearm and hand of elderly patients.Methods There were 21 old people with deep wounds on their forearms and hands.VSD technology was applied to make the wounds clean and fresh,and treatment methods were made to cure underlying diseases simultaneously.Different types of forearm flaps were designed according to the locations of the wounds,sizes of the wounds,and soft tissue conditions around the wounds.Furthermore,portable Doppler blood flow detector was used to locate the rotation points of the flaps,so that the flaps could be cut and wounds could then be repaired.Results 21 cases which used VSD technology combined with various types of forearm flap transplants to repair the elders' arm and hand deep wound surfaces were successful.VSD application average time was 7 days;the average bleeding volume was about 75ml;no local hematoma,infection and limb ischemia,etc.occurs after surgery;all the flaps were completely alive;follow-up results showed that the patients were satisfied with the duration and cost of treatment,appearance of the wound repair and recovery of limb function.Conclusion The application of VSD technology combined with forearm flap transplantation to repair the old arm and hand depth wound has some characters:tolerable to elderly patients,short flap surgery time,easy and fast operation,small damage,less surgical complications,high success rate of flap repair,and limb function can be saved to a greater extent.Although the appearance is not that satisfying,the application is safe enough for elderly patients.

Fluorescence imaging technology is an efficient,non-invasive imaging method without radioactivity,which was widely used in the medical field.In a variety of surgical scenarios,real-time imaging and reorganization of the target structure can be achieved with this technology,so as to promote the further development of precision surgery.However,the conventional visible light(400-700nm) and near-infrared-Ⅰ window(NIR-Ⅰ,700-900nm) are still insufficient in some aspects such as lower tissue penetration ability,which limit the development of fluorescence intraoperative imaging in the field of surgery.At present,with the rapid development of near-infrared-Ⅱ window(NIR-Ⅱ,1000-1700nm) fluorescence probes and devices,increasing studies have shown that NIR-Ⅱ fluorescence can improve the effect of near-infrared fluorescence imaging in operation.With longer wavelength,NIR-Ⅱ fluorescence can significantly reduce the absorption and scattering of photons in tissue and diminish autofluorescence of normal tissue.Besides,NIR-Ⅱ fluorescence has enhanced tissue penetration ability,micrometre resolution and higher signal-to-background ratio(SBR) for target structure.Therefore,we reviewed the progression of applications of NIR-Ⅱ fluorescence in solid tumor imaging,sentinel lymph node tracing,vascular,ureter and bile duct imaging in surgery and discusses its future development prospects.

The proteasome is a multi-protein complex capable of regulating the stability of hundreds of cellular proteins involved in almost all cellular processes.In most cases,proteins must be linked to a chain of ubiquitin molecules in order to be recognized and processed by the proteasome.The ubiquitin-proteasome system(UPS) regulates cell proliferation,apoptosis,angiogenesis and motility,processes that are particularly important in carcinogenesis.There is growing evidence that alterations in the UPS are associated with malignancy.Esophageal squamous cell carcinoma has a high incidence and a poor treatment prognosis in China and Southeast Asia.Therefore,we summarize the current literature on the involvement of UPS in esophageal squamous cell carcinoma to highlight its role in tumor development and to provide information for the study of therapeutic targets.

The development of the popularity of chest CT has led to an increasing number of lung cancer patients being detected at an early stage.Early lung cancer is often presented in the form of small lung nodules on chest CT,and small lung nodules are often clinically wedge-shaped or pulmonary segment resection.Because small lung nodules are small in diameter and low in density,surgeons cannot determine whether the resection range is sufficient.With the development of science and technology,the technology of localization of small lung nodules has also been greatly developed,but the specific role of each method in lung cancer surgery is not clear.We review the clinically relevant studies such as computed tomography-guided percutaneous puncture localization technique,bronchoscopic assisted positioning technology,computed tomography virtual 3D assisted positioning technology and intraoperative anatomical localization technique and summary the application progress of various localization techniques in lung cancer surgery.
