Objective: To observe the therapeutic effect of treating postoperative gastrointestinal syndrome with combined needles and herbs. Method: Altogether 117 in-patients were randomly allocated into the treatment group of 86 cases and control group of 31 cases. Point injection was mainly adopted in the treatment group plus Chinese herbal decoction, while Western medicine was adopted in the control group. And then the therapeutic effect of the two groups was compared. Result: The total effective rate of the treatment group and control group were 96.5% and 80.6% respectively, and the treatment course of the treatment group was significantly shorter than the control group (P ＜ 0.01). Conclusion: Combined needles and herbs have excellent effect in treating postoperative gastrointestinal syndrome and were superior to Western medicine.

Objective To investigate the effect of meridian-unblocking and mind-regulating acupuncture pretreatment on neurobehavioral functions and cerebral water content and explore its mechanism for modulating miRNA664 and MMP9 expressions in cerebral ischemia/reperfusion rats.Methods One hundred and thirty Wistar rats were randomized into group A (electroacupuncture pretreatment) of 30 rats, group B (moxibustion pretreatment) of 30 rats, group C (aspirin pretreatment) of 30 rats, group D (model) of 30 rats and group E (blank control) of 10 rats. Group A received electroacupuncture; group B, suspended moxibustion with moxa sticks; group C, an oral gavage of aspirin 10 mg/kg. A model of cerebral ischemia/reperfusion was made in every group after seven days. Rat neurobehavioral functions were observed and cerebral water content and relative miRNA664 and MMP9 expressions in the cortical region were determined at 24 hours after reperfusion.Results There was a statistically significant difference in the neurobehavioral score between group A, B, C or D and group E (P<0.01), between group A or B and group C (P<0.01) and between groups A and B (P<0.01). There were statistically significant differences in cerebral water content and relative miRNA664 and MMP9 expressions between group A, B, C or D and group E (P<0.01,P<0.05), between group A, B or C and group D (P<0.01), between group A or B and group C (P<0.01,P<0.05) and between groups A and B (P<0.01,P<0.05).Conclusions Meridian-unblocking and mind-regulating acupuncture pretreatment can effectively decrease the neurobehavioral score and cerebral water content and reduce relative MMP9 expression through modulating miRNA664 expression in cerebral ischemia/reperfusion rats. One of the mechanisms of Du meridian-unblocking and mind-regulating acupuncture pretreatment for protecting the brain may be reducing relative MMP9 expression, inducing tolerance to cerebral ischemia and relieving cerebral edema by the modulation of miRNA664 expression.

Objective:To express and purify the fusion protein of GST-FILIP-1L and prepare its polyclonal antibody. Methods:The constructed recombinant expression vectors pGEX-4T3-FILIP-1L were transformed into Escherichia Coli BL21. FILIP-1L fusion protein was induced by IPTG and purified by Glutathion Sepharse 4B . The rabbit was immunized by the purified fusion protein,and pro-duced serum with anti-FILIP-1L antibody. The titer of polyclonal antibody was detected by ELISA, the anti-FILIP-1L polyclonal antibody was purified by Active and its combining specificity with FILIP-1L protein was further identified by Western blot. Results:The GST-FILIP-1L fusion protein was highly expressed in E. coli, and its specific polyclonal antibody was obtained after the immunization. The polyclonal antibody purified by Active Ester Agrose was able to combine specially with FILIP-1L protein and transformed FILIP-1L protein in 293 cells and FILIP-1L protein of liver cancer cells, respectively. Conclusion: The GST-FILIP-1L fusion protein was expressed successfully,the anti-GST-FILIP-1L polyclonal antibodies with high titer and specificity are successfully prepared,these antibodies provide an useful experimental tool to research the biological function of the FILIP-1L protein.

Objective To study the academic level of randomized control trials(RCTs)published from 2004 to 2009 in Chinese Journal of Hepatobiliary Surgery.Methods Published work about RCTs in 72 issues of Chinese Journal of Hepatobiliary Surgery was searched by finding relevant articles published during 2004-2009.Correlated indexes including literature received time, literature publishing time, the total number of citations, number of citations in Chinese, number of citations in English, research funding situations, the number of authors, article affiliations in all RCTs, together with single(or multiple)center study situation, positive conclusions, the starting time, the end time,and number of patients recruited in clinical RCTs were extracted for aggregate analysis.Results During the past six years, a total of 135 articles of RCT were published in Chinese Journal of Hepatobiliary Surgery, accounting for 8.7% in all clinical studies.The average number of RCTs in each issue was 1.88.The average time for publishing time delay was 450 days.The total number of citations in RCTs was 1252 and the average number of RCTs for citations was 9.3.53 RCT studies were financed, accounting for 39% of the total number of research papers.Beijing Friendship Hospital attached to the Capital University of Medical Sciences had published 8 papers of RCT and it is the institution of publishing the largest number of such papers in the journal.The number of multi-center study for RCTs was one and all RCT studies had significant conclusions.The average research duraton in RCTs was 45 months.The total number of patients in 33 clinical RCTs was 2705 and the average number of patients recruited in each RCT was 82.Conclusion Chinese Journal of Hepatobiliary Surgery put emphasis on the strongest evidence and the most valuable RCT researches that have great significance in the field of domestic hepatobiliary surgery for clinical treatment and experimental research.

Objective:To investigate the application value of P-loop digestive tract recons-truction in pancreaticoduodenectomy (PD).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 21 ampullary disease patients undergoing PD in the Liuzhou People′s Hospital Affiliated to Guangxi Medical University from April to December 2020 were collected. There were 13 males and 8 females, aged from 35 to 76 years, with a median age of 60 years. All the 21 patients underwent PD and digestive tract reconstruction using P-loop method based on the Child reconstruction. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination or telephone interview to detect survival and discomfort symptoms of patients up to December 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or persentages. Results:(1) Surgical situations: all the 21 patients underwent PD successfully. The operation time, time of P-loop anastomosis and volume of intraoperative blood loss of 21 patients were (317±74)minutes, (14±3)minutes and 375 mL(range, 100-800 mL), respectively. Of the 21 patients, 17 cases had pancreatic texture as soft, 4 cases had pancreatic texture as hard, 3 cases had diameter of pancreas ≤3 mm, 18 cases had diameter of pancreas >3 mm, 14 cases were placed pancreatic duct stent, 7 cases were not placed pancreatic duct stent. (2) Postoperative situations: 2 of the 21 patients had grade A pancreatic fistula, and none of patient had grade B or grade C pancreatic fistula. One case had hepaticojejunal anastomotic fistula, 2 cases without pancreatic fistula had delayed gastric emptying and none of patient had abdominal infection or bleeding. The duration of postoperative hospital stay of 21 patients was (16±5)days, and none of patient died during postoperative 30 days. Results of postoperative histopathological examination showed there were 10 cases with duodenal papillary carcinoma, 4 cases with lower bile duct carcinoma, 3 cases with pancreatic head ductal adenocarcinoma, 1 case with duodenum stromal tumors, 1 case with gastric antrum carcinoma, 1 case with mass in the head of the pancreas of IgG4 and 1 case with choledochal cyst of type 3. (3) Follow-up: all 21 patients were followed up for 1.0 to 7.0 months, with a median follow-up time of 4.3 months. None of patient died. There was no abdominal pain, distension or dyspepsia during follow-up. One case was diagnosed as tumor liver metastasis at postoperative 5 months.Conclusion:P-loop digestive tract reconstruction in PD is safe and effective, with good short-term effect.
