Objective To determine whether rTFPI could inhibit vascular thrombosis and salvage random pattern skin flaps following AIRC in rat models.Methods From April,2013 to June,2015,30 adult male Sprague-Dawley rats were randomized into 3 groups;a control group,an avulsion injury with roll compaction (AIRC) group,and an AIRC plus rTFPI therapy group.An 8.0 cm× 2.5 cm random flap was raised on the dorsum of each rat.The AIRC and AIRC plus rTFPI flaps were then altered with a device designed to simulate avulsion injury with roll compaction.After flap closure primarily,treatment was initiated immediately and continued for 3 days.Phosphate buffered saline was used in the control group and the AIRC group,while the AIRC plus rTFPI group received the recombinant Tissue Factor Pathway Inhibitor.Laser Doppler flowmetry and infra-red thermalgraphy were used on postoperative day three to assess nicrocirculatory blood flow and viability of the avulsed flaps.At postoperative day seven,final flap survival was determined.Using SPSS19.0 statistical analysis.Results The flap survival in AIRC group was only (32.7 ± 5.2)％ versus (62.5 ± 6.5)％ in control group,but the flap survival significantly increased (51.6 ± 8.2)％ after topical injecting rTFPI in experimental group.Statistically significant differences exist (P ＜ 0.05) between every two groups.The detection results of Laser-Doppler flowmetry and infra-red thermography showed that perfusion arrived the centre of the flaps in experimental group,while perfusion only arrived the proximal part of the flaps in the AIRC control group.Conclusion rTFPI therapy is effective in reducing ischemic necrosis of random pattern flaps following avulsion injury in the rat model.It suggests that rTFPI therapy may play an important role in clinical salvage of the failing avulsion injuries with roll compaction.

Objective To investigate the effect of berberine on proliferation of neural stem cells(NSCs)induced by hydrogen peroxide(H2O2). Methods NSCs from Sprague-Dawley rats were isolated and purified by suspension culture. Cells were divided into a control group,H2O2group(NSCs exposed to H2O2injury),berberine group(NSCs were incubated with berberine concentrations ranging from 0.5 to 20 μmol/L and exposed to H2O2), and DAPT(a blocker of the Notch signaling pathway)group. Cell viability was evaluated using the Cell Counting Kit-8 assay. Proliferation of NSCs was evaluated by a neurosphere formation assay and Ki67 protein expression. Expression of key proteins in the Notch signaling pathway(including notch1 and hes1)in response to berberine treatment or DAPT(a Notch inhibitor)was determined by Western blotting. Results Cell viability of NSCs was significantly increased by berberine compared with the H2O2group. The neurosphere growth assay showed that 5 or 10 μmol/L berberine increased NSC proliferation. The ratio of Ki67 +/DAPI cells and notch1 and hes1 protein expression increased significantly compared with the H2O2group. Conclusions Berberine treatment upregulates Notch signaling in NSCs,whereas DAPT attenuates these effects. Berberine is a drug that promotes NSC proliferation and exerts a protective effect on NSCs via the Notch signaling pathway.

Objective:To explore the effectiveness of blood glucose monitoring at different frequencies on the control of blood glucose in overweight/obese prediabetes population on the basis of health education, and to provide a basis for blood glucose monitoring and management in prediabetes population.Methods:A randomized controlled study was used. 90 prediabetes patients from the Physical Examination Center/Endocrine Clinic/Endocrine Ward of the First Affiliated Hospital of China Medical University from January to March 2021 were selected by continuous sampling method, and were randomly divided into the group A, B and C by lottery method, with 30 patients in each group, and the study period was 12 months. Group A, B and C received unified health education guidance at enrollment, 6-month follow-up, and 12-month follow-up. Group A underwent blood glucose monitoring every 6 months, group B underwent blood glucose monitoring every 3 months, group C underwent blood glucose monitoring every month. Recorded and compared the levels of glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2-hour post-load blood glucose (2 hPG), and body mass index (BMI) of three groups at the time points of enrollment, 6-month follow-up, and 12-month follow-up.Results:There were 15 males and 15 females in the group A, 14 males and 16 females in the group B, 12 males and 18 females in the group C. The ages in the group A, B and C were (48.37 ± 10.80), (49.20 ± 9.25) and (44.77 ± 12.28) years old respectively. At the time point of 12-month follow-up, the HbA1c in the group A, B and C were (6.01 ± 0.36)%, (5.82 ± 0.35)% and (5.64 ± 0.27)%, the difference was significant ( F=9.72, P<0.05); the FPG in the group A, B and C were (5.64 ± 0.88), (5.05 ± 0.53) and (4.98 ± 0.48)mmol/L, the difference was significant ( F=9.23, P<0.05); the 2 hPG in the group A, B and C were (9.38 ± 1.23), (8.23 ± 0.72) and (7.71 ± 0.86) mmol/L, the difference was significant ( F=23.89, P<0.05); the BMI in the group A, B and C were (28.52 ± 4.24), (27.02 ± 2.67) and (25.56 ± 1.34) kg/m 2, the difference was significant ( F=7.37, P<0.05). Conclusions:On the basis of health education, compared with the routine blood glucose monitoring once every six months, blood glucose monitoring once every three months and once every month can improve the blood glucose control and BMI level of overweight/obese young and middle-aged people with prediabetes, and provide a basis for seeking an effective and economic blood glucose monitoring mode in clinical practice.

Objective To investigate the safety and short-term outcomes of laparoscopic abdominoperineal resection with pelvic peritoneum closure (LARP-PPC) for low rectal cancer.Methods The retrospective cohort study was conducted.The clinicopathological data of 132 patients with low rectal cancer who were admitted to Ruijin Hospital of Shanghai JiaoTong University School of Medicine from January 2014 to December 2017 were collected.There were 81 males and 51 females,aged from 45 to 83 years,with an average age of 62 years.Among the 132 patients,60 undergoing LARP-PPC were allocated into LARP-PPC group,and 72 patients undergoing conventional LARP were allocated into LARP group.All the patients received standardized preoperative and postoperative treatments.Observation indicators:(1) surgical and postoperative conditions;(2) postoperative pathological examination;(3) postoperative complications.The measurement data with normal distribution were expressed as Mean±SD,and the t test was used for comparison between groups.The measurement data with skewed distribution were expressed as M (range),and the Mann-Whitney U test was used for comparison between groups.The count data were expressed as absolute numbers,and the chi-square test or the Fisher exact probability was used for comparison between groups.Mann-Whitney U test was used for comparison of ordinal data between groups.Results (1) Surgery and postoperative conditions:all the patients in the two groups underwent successful surgery without conversion to open surgery.The operation time,volume of intraoperative blood loss,time to first flatus,and time to first liquid intake of the LARP-PPC group were (163±45) minutes,168 mL(range,85-280 mL),2 days(range,1-5 days),3 days(range,2-6 days),versus (155±39) minutes,160 mL(range,100-305 mL),3 days(range,1-7 days),4 days(range,2-7 days) of the LARP group;there was no differencebetween the two group (t =1.113,Z =-1.623,-1.468,-0.321,P＞0.05).The duration of postoperative hospital stay in the LARP-PPC group and the LARP group were 16 days (range,11-21 days) and 19 days (14-24 days),respectively,with a significant difference between the two groups (Z =-5.888,P＜0.05)].In the LARP-PPC group,time of PPC was (13± 3) minutes.(2) Postoperative pathological examination:the length of specimen,the number of lymph node dissection,tumor diameter,cases with high-,middle-,and low-differentiated tumor in the LARP-PPC group was (18±4)cm,16±t5,(3.7±1.4)cm,10,34,16 in the LARP-PPC group,and (18±4)cm,16±5,(3.9±1.5) cm,13,41,18 in the LARP group,showing no significant difference between the two groups (t =0.779,0.390,0.703,Z=-0.267,P＞0.05).(3) Postoperative complications:cases with perineal wound infection,delayed perineal wound healing,intestinal obstruction,and perineal hernia were 2,1,1,0 in the LARP-PPC group,and 12,10,8,6 in the LARP group,showing significant differences between the two groups (x2 =6.137,6.400,P＜0.05).There were 2 and 4 patients with urinary tract infection in the LARP-PPC group and the LARP group,respectively,showing no significant difference between the two groups (P ＞ 0.05).Conclusion LARP-PPC is safe and feasible for the treatment of low rectal cancer,which can significantly reduce postoperative perineal-related complications and consequently shorten postoperative hospital stay.
