Objective To explore the corrective role of lived combined Bacillus subtilis and Enterococcus faecium enteric-coated capsules on the bacteria overgrowth in small intestinal (SIBO)and assess the efficacy and possible mechanism of it in the treatment of diarrhea predominant irritable bowel syndrome (IBS-D).Methods From May to August 2013,IBS-D patients were collected.Screened by lactulose hydrogen breath test (LHBT),and a total of 60 SIBO positive patients were enrolled in the study and divided into experimental group and control group.Live combined Bacillus subtilis and Enterococcus faecium enteric were given to the experimental group and starch given to the control group,both were capsules,each 250 mg,three times per day,two capsules each time,and the treatment course was four weeks.Before and after administration a questionnaire was conducted in the study objects,including basic information (age,gender,disease type,family history and accompanied diseases) and the severe degree of the symptoms (abdominal pain,bloating,abdominal discomfort,increased frequency of defecation,defecation urgency,defecation endless,defecation hard,bowel and exhaust).Fasting peripheral venous blood was taken from the study individuals before and after administration.The level of interleukin (IL)-1β,IL-6,IL-10,IL-12 and tumor necrosis fator-α(TNF-α) in serum were detected by enzyme linked immunosorbent assay(ELISA).t-test was performed for measurement data comparison between two groups,and chi-square test was for count data comparison.Results Among 60 SIBO positive IBS-D patients,30 patients were in experimental group and 30 in control group.The SIBO negative conversion rate of experimental group and control group was 63.3 ％(19/30) and 30.0％ (9/30),the difference was statistically significant (x2 =6.696,P＜0.05).Before and after administration,in control group there were no significant differences in severe degree scoring of abdominal pain,bloating,abdominal discomfort,increased frequency of defecation,defecation urgency,defecation endless,defecation hard,bowel and exhaust or the level of TNF-α,IL-1β,IL-6,IL-10 and IL-12 (all P＞0.05).In experimental group,before and after administration there were statistically significant differences in severe degree scoring of abdominal floating (2.97 ± 1.45 vs 2.61±1.28),level of IL 1β ((1390.81±103.95) ng/L vs (1209.76±113.26) ng/L)and IL-10/IL-12 (4.94±0.74 vs 5.30±0.43),the differences were statistically significant (t=2.052,5.279 and 2.282,all P＜0.05).There were no signinficant differences in other items (all P＞0.05).Conclusions Lived combined Bacillus subtilis and Enterococcus faecium enteric coated capsules could alleviate the symptoms of abdominal floating.The possible mechanism may related with correcting SIBO,inhibiting low degree of inflammation reaction and regulating the inflammatory cytokines.

To a certain extent, precision medicine based on individualized medical treatment process, like syndrome differentiation of traditional Chinese medicine. This paper mainly analyzed the similarities and differences of theory, practice and development between precision medicine and TCM syndrome differentiation. After the analysis, we found that these two medicine body could be integrated to improve the progress of medicine albeit some differences.

Heat shock response is a classical stress-induced regulatory system in bacteria, character-ized by extensive transcriptional reprogramming. To compare the impact of heat stress on the tran-scriptome and translatome in Escherichia coli, we conducted ribosome profiling in parallel with RNA-Seq to investigate the alterations in transcription and translation efficiency when E. coli cells were exposed to a mild heat stress (from 30 ?C to 45 ?C). While general changes in ribosome foot-prints correlate with the changes of mRNA transcripts upon heat stress, a number of genes show differential changes at the transcription and translation levels. Translation efficiency of a few genes that are related to environment stimulus response is up-regulated, and in contrast, some genes func-tioning in mRNA translation and amino acid biosynthesis are down-regulated at the translation level in response to heat stress. Moreover, our ribosome occupancy data suggest that in general ribosomes accumulate remarkably in the starting regions of ORFs upon heat stress. This study provides additional insights into bacterial gene expression in response to heat stress, and suggests the presence of stress-induced but yet-to-be characterized cellular regulatory mechanisms of gene expression at translation level.

In the past 30 years, laparoscopic hepatectomy has developed rapidly, which multi-dimensionally promoted the innovation of hepatectomy technology and strategy. This is mainly attributed to the key factors such as the improvement of domestic and foreign scholars′ under-standing of liver anatomy, the conversion and application of laparotomy technology, the expansion of laparoscopic vision and the feedback in surgery related fields. The authors summarize the enlighten-ment, development, promotion and sublimation of laparoscopic hepatectomy, and discuss the classi-fication and evolution of the surgical approach of laparoscopic hepatectomy.

Objective:To investigate the safety of minimally invasive liver resection for resectable hepatocellular carcinoma (HCC) complicated with portal hypertension.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 807 patients with resectable HCC who underwent minimally invasive liver resection in 8 medical centers, including Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine et al, from June 2011 to November 2022 were collected. There were 670 males and 137 females, aged 58(50,66)years. Of the 807 patients, 173 cases with portal hypertension were divided into the portal hypertension group, and 634 cases without portal hypertension were divided into the non-portal hypertension group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and post-operative situations; (3) subgroup analysis. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.001. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was constructed using the non-parameter rank sun test. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 807 patients, 268 cases were successfully matched, including 134 cases in the portal hypertension group and 134 cases in the non-portal hypertension group. The elimination of the tumor diameter and robot-assisted surgery confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. The occlusion time of porta hepatis, cases with intraoperative blood transfusion, cases with postoperative complication, cases with complication >Ⅱ grade of Clavien-Dindo classification, cases of Clavien-Dindo classification as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, cases with liver related complication were 27.0(15.0,43.0)minutes, 33, 55, 15, 13, 29, 14, 1, 37 in the portal hypertension group, versus 35.0(22.0,60.0)minutes, 17, 25, 5, 14, 9, 4, 1, 13 in the non-portal hypertension group, showing significant differences in the above indicators between the two groups ( Z=-2.15, χ2=6.30, 16.39, 4.38, 20.72, 14.16, P<0.05). (3) Subgroup analysis. Results of subgroups analysis showed that in cases with major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 243.5(174.6,296.3)minutes, 200.0(150.0,600.0)mL, 7.5(6.0,13.0)days in the portal hypertension group, versus 270.0(180.0,314.5)minutes, 200.0 (75.0,450.0)mL, 7.0(5.5,10.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.54, -1.73, -0.92, P>0.05). In cases with non-major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 8.0(5.0,10.0)days in the portal hypertension group, versus 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.5,9.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-1.39, -0.10, 1.05, P>0.05). In cases with anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 210.0(150.0,285.0)minutes, 150.0(50.0,200.0)mL, 8.0(6.0,9.3)days in the portal hypertension group, versus 225.5(146.3,306.8)minutes, 100.0(50.0,250.0)mL, 7.0(6.0,9.0)days in the non-portal hypertension group, showing no significant difference in the above indica-tors between the two groups ( Z=-0.75, -0.26, -0.91, P>0.05). In cases with non-anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 173.5(120.0,231.5)minutes, 175.0(50.0,300.0)mL, 7.0(5.0,11.0)days in the portal hyper-tension group, versus 186.0(123.0,262.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.0,9.5)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.97, -1.12, -0.98, P>0.05). Conclusion:Minimally invasive liver resection or even major liver resection is safe and feasible for screened HCC patients complicated with portal hyper-tension, but attention should be paid to the prevention and treatment of postoperative complications.

There were 92 males and 51 females with age of (64±11) years (range: 53 to 72 years). Bismuth type: type I, 38 cases (26.6%), type Ⅱ, 19 cases (13.3%), type Ⅲa, 15 cases (10.5%), type Ⅲb, 28 cases (19.6%) and type Ⅳ, 43 cases (30.0%). The patients within the first 10 operation cases in each operation time (the first 10 patients in each operation team) were divided into group A (77 cases), and the patients after 10 cases in each operation time were classified as group B (66 cases); the cases with more than 10 cases in the center were further divided into group A 1 (116 cases), and the center with less than 10 cases was set as group A 2 (27 cases). T test or Wilcoxon test was used to compare the measurement data between groups, and the chi square test or Fisher exact probability method was used to compare the counting data between groups. Kaplan Meier curve was used for survival analysis. Results:All patients successfully completed laparoscopic procedure. The mean operation time was (421.3±153.4) minutes (range: 159 to 770 minutes), and the intraoperative blood loss was 100 to 1 500 ml (median was 300 ml) .Recent post-operative complications contained bile leakage, abdominal bleeding, abdominal infection, gastrointestinal bleeding, and delay gastric emptying, pulmonary infection, liver failure, et al.The post-operative hospital stay was (15.9±9.2) days. The operation time in group B was relatively reduced ( (429.5±190.7)minutes vs. (492.3±173.1)minutes, t=2.063, P=0.041) and the blood loss (465 ml vs. 200 ml) was also reduced ( Z=2.021, P=0.043) than that in group B. The incidence of postoperative biliary fistula and lung infection in patients in group A was significantly higher than that in group B (χ 2=4.341, 0.007; P=0.037, 0.047) .Compared with group A 2, the operation time in group A 1 was relatively reduced( (416.3±176.5)minutes vs. (498.1±190.4)minutes, t=2.136, P=0.034) , the incidence of bile leakage and abdominal cavity infection in group A 1 was lower than that in group A 2 (χ 2=7.537, 3.162; P=0.006, 0.046) . Kaplan Meier survival curve showed that the difference of short-term survival time between group A and group B was statistically significant ( P<0.05) . Conclusions:The completion of laparoscopic hilar cholangiocarcinoma radical surgery is based on improved surgical skills, and proficiency in standardized operation procedures.It is feasible for laparoscopic radical resection of hilar cholangiocarcinoma to well experienced surgeon with cases be strictly screened, but it is not recommended for widespread promotion at this exploratory stage.

As the reserve force of traditional Chinese medicine (TCM), students in TCM colleges or universities play an important role in promoting the development of TCM. However, these students have disadvantages in humanistic quality, such as the lack of humanistic knowledge, awareness of the fear of life, and the inadequacy of professional morality, which may affect their future job performance. In view of the present situation of the humanistic quality of students in TCM colleges or universities, we analyzed the factors affecting their humanistic quality and proposed to build a platform to exchange TCM culture, enrich teachers' knowledge of TCM culture and cultivate the professional ethics of students in TCM colleges or universities, in combination with the core values of TCM culture such as profoundness, reality, benevolence, effectiveness, so as to improve students' overall humanistic quality.
