Objective To investigate the clinical efficacy and mechanism of vacuum-assisted closure (VAC) in the preoperative and postoperative treatment of bedsore united with skin flap.Methods Twenty two cases with bedsore were randomly divided into experimental and control groups.In the control group,the surgery of flap was performed after the treatment of continuous negative pressure about 7-10 days and the VAC was not applied after operation.While in the experimental group,VAC was not used before operation.It was applied on flaps as soon as sutured the border of flap and decubitus ulcers and removed after 7-10 days.By comparing the general appearance of two groups,microvessel count and the detection rate of bacterial culture and other indicators,the clinical effects of two treatments were investigated and the preliminary mechanism was analyzed.Results After preoperative VAC treatment,11 cases of control group showed a little granulation tissue growth,less subcutaneous hematoma and wound effusion,increased microvessel count and negative bacterial culture.However,there were 4 cases of death cavity residual,subcutaneous hematoma and wound effusion,positive bacterial culture and another 4 cases of delayed healing with skin flap repairing bedsore.The application of VAC in experimental group showed close contact of flap with the basement,less effusion,increased microvessel count and negative bacterial culture.One case of skin flap had a small area of separation,after the dressing of skin and the flap survived.The other wounds healed by first intention.Conclusions The use of VAC to repair bedsore can reduce the number of operation,and it is beneficial to the flap survival.

This article introduced the experience of Professor YU Yun in treating the primary carcinoma of liver by using acupuncture after pulse diagnosis. Professor YU thinks that the overall pathogenesis of liver cancer is deficiency of zang-fu organs, so the cancer cells can invade and occupy in the liver. Therefore, Professor YU uses the way of supporting the healthy qi and driving out the cancer as the treatment principle from multiple organs and meridians. On the basis of the theories of Nei Jing, Professor YU creates the acupuncture after pulse diagnosis. He feels the pulse on the basis of four pulses: Cunkou, Renying, Chongyang, and Taixi. According to the feelings of the pulses, he compares the size and speed, strong or weak, smooth or nonfluency of the four pulses. In treatment, he uses reducing method when the pulse is strong and fast, and tonic method when the pulse is weak and slow. He chooses the main acupuncture points on head, face, belly, flank and lower limbs. According to the experience, Professor YU uses gold needle in tonic method and uses silver needle in reducing method. In this way, the acupuncture after pulse diagnosis can regulate zang-fu organs and meridians, yin and yang, qi and blood, and promote blood circulation for removing blood stasis and resolving dampness, and attack the retained fluid and tumour in the liver, and combined with adjunct points to treat cancer.

Objective:To evaluate the feasibility of a predictire model composed of non-specific test indexes in early diagnosis of gastric cancer.Methods:From the database of electronic medical record system of Shanghai Changhai Hospital, a total of 24 615 case records were included from January 1, 2010 to April 30, 2019, including 10 497 cases of gastric cancer, 5 198 cases of precancerous diseases, and 8 920 cases of health examination. Through stratified random sampling, the study population was divided into validation set, training set and test set. After data processing and quality control for all laboratory variables, the optimal machine learning algorithm and diagnostic efficiency grouping were selected through four machine learning algorithms, induding the gradient boosting decision tree, random forest, support vector machine, and artificial neural network, and the data were trained by backward stepwise regression method to build the best feature model.Result:In this study, a diagnostic model V22 consisting of 22 routine testing parameters was established. V22 could distinguish early gastric cancer from control group composed of healthy group and precancerous disease, AUC was 0.808, the sensitivity was 85.7%, and the specificity was 91.9%. For CEA negative gastric cancer, V22 also showed high diagnostic accuracy, AUC was 0.801.Conclusion:V22 was a valuable model for the diagnosis of gastric cancer. V22 was an auxiliary diagnostic model of gastric cancer with clinical application value, which could well distinguish early gastric cancer from the control group composed of healthy group and precancerous disease, and the detection rate of early gastric cancer was better than the traditional tumor marker CEA.

Objective To assess the effect of anemia on long-term outcomes in patients with acute coronary syndrome(ACS) undergoing pereutaneous coronary intervention(PCI). Methods In 3136 patients presenting with ACS,636 patients were anemic. The clinical features, mortality and major cardiocerebral events including non-fatal acute myocardial infaret,revascularization and non-fatal cerebral stroke were compared in patients with or without anemia. The average follow-up period was 550 days. Results Anemic patients were older and had a higher percentage of comorbidities compared with nonanemic cohorts. Compared with nonanemic patients, anemic patients had higher mortality (4.7% versus 1.5% ,P <0. 001) and a higher major adverse end point events,including nonfatalmyocardial infarction, stroke and revaseularization (14.2% versus 11.0%, P = 0.032). After adjustment for comorbidities, anemia was associated with a higher risk of mortality after percutaneous coronary intervention (adjusted hazard rate ratioRR2. 166 ;95% CI 1. 298-3. 612 ;P =0.003). Conclusion Anemia before PCI is an independent factor for predicting the long-term mortality of ACS.
