Hemorrhoid refers to soft vein mass formed by varicosity of submucosal veins around the end of the rectum and subcutanceous veins of the anal canal. It is the most common anorectal disease. This article summarized the regular patterns, features and advantages of Professor Yu Hai-Bo's acupuncture-moxibustion therapy for hemorrhoids, in order to guide the acupuncture treatment for hemorrhoids.

Objective: To investigate the feasibility of in vitro release models of injectable implants. Methods: An RP-HPLC method was established for determination of norfloxacin (NF). The in vitro release profiles of injectable implants in four release models, including direct injection model, one-way cylinder, dialysis tube and home-made cylinder, were studied and compared with the in vivo release profiles. Results: The in vivo release of NF from injectable implants was much faster than the in vitro release of NF. The in vivo release was close to the zero-order release kinetics in the sustained release phase (1-20 d, r=0.993 5), while the in vitro release could be divided into slow phase and fast phase with 15 d as the turning point. Of the four in vitro release models, home-made cylinder showed the closest initial release to the initial release of NF in vivo. Conclusion: All the above four release models have limitations; they can not well reflect the in vivo release profiles of injectable implants; and further studies are needed for the in vitro release model of injectable implants.

Objective To investigate the effects of total nutrient admixture (TNA) on the recovery of patients with gastric cancer after radical gastrectomy.Methods The clinical data of 50 patients with gastric cancer who were admitted to the Affiliated Hospital of Luzhou Medical College between March 2013 and March 2014 were retrospectively analyzed.Among 50 patients receiving radical gastrectomy,26 patients receiving TNA were allocated to the experimental group and 24 patients receiving conventional fluid infusion were allocated to the control group.Patients in the experimental group received the nutritional support therapy using TNA at preoperative day 5 and at postoperative days 1-5,and patients in the control group received the postoperative intravenous rehydration including water,glucose,electrolyte,vitamins and micro elements.The nutritional indexes [albumin (Alb),prealbumin,transferrin and hemoglobin (Hb)],time to anal exsufflation,incidence of complications (wound infection,anastomotic leakage,blooding and intestinal obstruction) and duration of hospital stay were observed before nutritional support therapy and at postoperative day 8.The count data were analyzed using the chi-square test.The chi-square value of correction for continuity was used when 1 ≤ minimum theoretical frequency ≤ 5.The measurement data with normal distribution were presented as (x) ±s and analyzed using the t test or repeated measures ANOVA.The ordinal data were analyzed by the analysis of variance.Results The Alb,prealbumin,transferrin and Hb in the experimental group were (38.6 ± 2.0) g/L,(281 ± 33) mg/L,(2.5 ± 0.9) g/L and (111 ± 20) g/L before nutritional support therapy and (38.2 ± 1.9) g/L,(277 ± 16) mg/L,(2.3 ± 1.1) g/L and (112 ± 37) g/L at postoperative day 8,respectivley.The Alb,prealbumin,transferrin and Hb in the control group were (38.3 ±2.4) g/L,(287 ± 34) mg/L,(2.4 ± 1.1) g/L and (107 ± 21) g/L before nutritional support therapy and (30.3 ±2.3) g/L,(190 ± 41) mg/L,(1.6 ± 0.3) g/L and (93 ± 22) g/L at postoperative day 8,respectivley.There were significant differences in the nutritional indexes at postoperative day 8 between the 2 groups (F =174.042,95.637,9.529,4.919,P ＜ 0.05).The time to anal exsufflation in the experimental group were (52 ± 11) hours,which was significantly different from (70 ± 12) hours in the control group (t =-5.176,P ＜ 0.05).The incidence of complications was 15.4％ (4/26) in the experimental group,which was significantly different from 58.3％ (14/24) in the control group (x2=6.460,P ＜0.05).Patients with complications in the 2 groups were cured by anti-infective or symptomatic treatment.The duration of hospital stay was (9 ± 3) days in the experimental group and (12 ± 4) days in the control group,with a significant difference between the 2 groups (t =-2.912,P ＜ 0.05).Conclusion TNA can improve the nutritional status of patients after radical gastrectomy in a short time.It could help patients to get through the perioperative period smoothly,and enhance the postoperative recovery.

BACKGROUND:Although the therapeutic effect of total knee arthroplasty for severe gonarthritis is reliable, deep vein thrombosis also occurred in many patients. Therefore, deep vein thrombosis has been a major reason for unexpected death after total knee arthroplasty. OBJECTIVE:To study the incidence of deep vein thrombosis after total knee arthroplasty with general and epidural anesthesia. METHODS:We searched“PubMed”,“Medline”,“Elsevier”,“Embase”, Cochrane library,“Wanfang”,“China National Knowledge Infrastructure”for papers published from January 2000 to March 2015. The mesh words were“total knee arthroplasty”,“TKA”,“thrombosis”,“DVT”,“randomized control ed trial”,“RCT”for studies concerning deep vein thrombosis after total knee arthroplasty with different anesthetic methods. The double blind method was used for data extraction and assessment of literature quality. Revman5.3 software was utilized to analyze the extracted data using meta-analysis. RESULTS AND CONCLUSION:There were 8 studies including 885 patients. The heterogeneity of the included studies was very low (I2=0, P=0.72). The combined OR was 0.25 (95%confidence interval:0.18, 1.35), indicating that continuous epidural anesthesia in total knee arthroplasty could apparently reduce the possible formation of postoperative deep vein thrombosis. Because of lack of the changes in coagulation factors under general anesthesia and epidural anesthesia, the mechanism underlying epidural anesthesia to reduce the incidence of deep vein thrombosis deserves further investigations. Among patients with deep vein thrombosis, continuous epidural anesthesia could diminish the possible formation of deep vein thrombosis. Thus, epidural anesthesia should be used firstly for knee replacement in patients with high risk of deep vein thrombosis.

Objective To investigate changes in the expression of apurinic/apyrimidinic endonuclease (APE) and the oxidative DNA damage marker 8 OHdG in distant hippocampus regions of the rat brain after focal cerebral ischemia of the middle cerebral artery.Methods SD rats were divided into the sham surgery group and the pMCAO group (induced by middle cerebral artery occlusion).Pathological changes in brain tissues were examined at 2 h,6 h,12 h,24 h,48 h and 72 h.The expression of APE and 8-OHdG was measured by immunohistochemical staining methods.TUNEL staining was performed to detect apoptosis.Results Reduction of APE expression in the CA1 region of the hippocampus on the ischemia side appeared at 2 h in the pMCAO group and continued as ischemia persisted (F=11.91,P＜0.05).The expression of 8OHdG and TUNEL immunoreactivity in the CA1 region of the hippocampus on the ischemia side were first observed at 6h in the pMCAO group and intensified during the remainder of induced ischemia (F=9.23 and 10.46 respectively,P＜0.05 for both).Compared with the sham group,8-OHdG expression and TUNEL immunoreactivity in the pMCAO group were at nearly the same levels from 24 h to 72h.Conclusions Oxidative DNA damage occurs in hippocampus regions of the rat brain after experimentally induced focal cerebral ischemia of the middle cerebral artery.APE expression declines in regions distant from focal cerebral ischemia.Development and accumulation of oxidative DNA damage can induce apoptosis in certain brain regions.

Objective To observe the contents of acid phosphatase (ACP) of Oncomelania snails infected with Schistosma japonicum.Methods Both the blood lymphocytes of positive and negative Oncomelania snails were dyed with the histochemistry staining method and their ACPs were observed under a microscope. Results The contents of ACP in the positive Oncomelania snails increased, being significantly higher than those in the negative snails. Conclusion The contents of ACP increase in Oncomelania snails infected with Schistosoma japonicum and ACP may have the defence function.
