Objective To investigate the preventive effects of anti-viral therapy in combination with transcatheter arteria chemoembolization (TACE) on recurrence of HBV-related hepatocellular carcinoma (HCC) after operation. Methods According to selection standards, 49 patients treated in this hospital from January 2003 to June 2009 were enrolled in this study and divided into a control group and combined group.The cumulative tumor-free survival rate, cumulative survival rate, the 1-, 2- and 3-year recurrence rates and cumulative recurrence rates were determined in all the patients and compared between the 2 groups. Results The cumulative tumor-free survival rate and cumulative survival rate were significantly higher in the combined group than in the control group (P=0. 019, 0. 008). The 1-, 2-, and 3-recurrence rates were 24% vs. 38.9%, 28% vs. 33.3%, and 28% vs. 22.2% in the combined group and control group, respectively. The 1-, 2-, and 3-year cumulative recurrence rates were 24% vs. 38. 9%, 52% vs. 72. 2%, and 80% vs.94. 4% in the combined group and control group, respectively. Conclusion Anti-viral therapy in combination with TACE can exert significant preventive effects on recurrence of HBV-related HCC after operation.

Objective To study the inhibitory effects of andrographis paniculata and silybum marianum on the efflux system of MRSA 41577. Methods Inhibitory effects of andrographis paniculata and silybum marianum on efflux system of MRSA 41577 was evaluated using fluorescence spectrophotometry.PCR was applied to detect the norA efflux gene.By RT-PCR method for detection of andrographis paniculata and silybum marianum influence of the expression of norA efflux gene.Results Andrographis paniculata and silybum marianum significantly increased the accumulation of ciprofloxacin in MRSA 41577 in a time-dependent manner.At 12 minute, andrographis paniculata and silybum marianum respectively increased ciprofloxacin in MRSA41577 by 49% and 76%( P <0.05 ) , which is superior to that of reserpine. Further mechanism studies indicated that andrographis paniculata and silybum marianumcould reduce the expression of norA in MRSA 41577.After incubated with andrographis paniculata and silybum marianum for 16 h, the relative expression of norA of MRSA41577 was respectively reduced by 35% and 42% ( P <0.05 ). Conclusion Andrographis paniculata and silybum marianumcould inhibit MRSA efflux system through reducing pathogen ’s expression of norA and NorA protein.

Objective To investigate the clinical efficacy of prucalopride in the treatment of severe chronic constipation.Methods The clinical data of 60 patients with severe chronic constipation [slow transit constipation (STC), functional defecation disorder (FDD) and constipation-predominant irritable bowel syndrome (IBS-C)] who were admitted to the Third Affiliated Hospital of Nanjing University of Chinese Medicine from February to August 2014 were prospectively analyzed.A prospective, clinical observational study was performed.Treatment plans included that patients withdrew the initial treatments of laxative and exema and took orally 2 mg prucalopride once daily for 2 weeks, and continued to be treated by oral prucalopride if frequency of the spontaneous complete bowel movement (SCBM) per week was satisfactory (or improvement of symptoms was more than 50％) till 4 weeks, and then were followed up after stopping prucalopride.If improvement of symptoms was less than 50％ after 2-week treatment, other treatment plans were performed according to symptoms of patients from week 3 to week 6 : (1) for patients with STC, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients were satisfied with frequency of SCBM per week and without improvement of abdominal distension;prucalopride + Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week with abdominal distension or poor stool output;oral prucalopride + acupuncture were administered if patients were unsatisfied with frequency of SCBM per week or less bowel movements and without improvement of abdominal distension or poor stool output.(2) For patients with FDD, oral prucalopride + acupuncture + biofeed-back therapy were administered.(3) For patients with IBS-C, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients had abdominal distension;prucalopride Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week and no improvement of abdominal distension or poor stool output.All patients used a diary for recording the frequency of SCBM per week, stool consistence, exertion in defecation and adverse reactions, which was submitted to doctors for inputting data at the return visit weekly.Results There was good overall medicine compliance in patients.Of 60 patients, 43 patients completed treatments (21 with STC, 11 with FDD and 11 with IBS-C).After 2-week treatment, there were 19 patients with satisfied therapeutic effects, 14 with improvement of constipation and 10 with poor therapeutic effects.After 4-week treatment, constipation in 17 patients was cured, constipation in 18 patients was improved,and constipation in 8 patients was not improved.Nineteen of 60 patients were complicated with adverse reactions within 1 week of the medication, including 6 patients dropping out of the trial due to medication withdrawal and others with improvement by symptomatic treatment or spontaneous remission.Conclusions Prucalopride is effective for the treatment of severe chronic constipation with a good toleration, and it can improve the overall satisfaction of patients combined with Chinese herb decoction and acupuncture.

Objective To investigate the expression of fragile histidine triad(FHIT),fibronectin (FN) and phosphatase and tensin homology deleted on chromosome ten( PTEN )in human hepatocellular carcinomas (HCC) and their relationship with pathological characteristics and prognosis of HCC.Methods Immunohistochemistry was used to detect expression of FHIT,FN and PTEN in cancerous tissues from 138 HCC patients.The correlation between their expression and clinicpathological features and prognosis were analyzed.Results FHIT,FN,PTEN protein expressed differently between HCC and adjacent mucosa ( respectively x2 =5.968,7.380,4.962,all P ＜ 0.05 ),and the expression level was different with tumor size,tumor number,grades and tumor lymph node metastasis( P ＜ 0.05 ).In FHIT and FN positive group,the recurrence free survival rates were lower than those in negative groups( respectively x2 =4.443,9.867,all P ＜0.05),while in PTEN positive group patients' recurrence free survival rates were higher than those with PTEN negative expression ( x2 =4.199,P ＜ 0.05 ).Conclusions FHIT,FN,PTEN were abnormally expressed in HCC.Positive expression of FHIT and FN predicts poor prognosis,while positive PTEN indicates fair prognosis.

Objective To investigate the risk factors of laparoscopic cholecystectomy (LC) in patients with previous gastrectomy.Methods This retrospective study reviewed a database of patients who underwent LC at our hospital during the period of Jan 2010 and May 2015.Results Comparesd with those of no history of gastrectomy the average operation time in patients with previous gastrectomy was longer (t =15.608,P ＜ 0.05) the intraoperative blood loss was higher (t =3.061,P ＜ 0.05),and the operation time of patients with a long interval (＞ 5 years) between gastrectomy and LC was shorter (t =6.405,P ＜ 0.01).The conversion rate did not differ between the two groups (P ＞ 0.05),but the conversion rate significantly reduced after a comprehensive preoperative evaluation procedure (x2 =15.282,P ＜ 0.01).Conclusion LC for benign gallbladder diseases is safe,effective and feasible in patients with a history of gastrectomy,if a comprehensive preoperative evaluation is adopted and in experinced hands.

Objective To study the anti-rheumatoid arthritis mechanism of Ermiao powder by high-throughput urine metabolomics.Methods The rats were randomly divided into control group,model group and administration group with 8 rats in each group.The rat model of rheumatoid arthritis was established by intradermal injection of complete Freund's adjuvant.Rats in control group were given Ermiao power solution 0.108 g/ml by gavage.The degree of joint swelling in rats was observed and scored.On this basis,metabolic data of rat urine samples were collected for metabolomic analysis.Unsupervised and supervised pattern recognition technology was used to analyze the high-throughput biological information data and reduce the dimension.Metabolic information related to rheumatoid arthritis was screened and focused to clarify the pathogenesis of rheumatoid arthritis and the therapeutic mechanism of Ermiao power.Results Compared with the model group,the swelling degree of the foot (1.93 ± 0.11 vs.2.36 ± 0.19) in Ermiao power group significantly decreased (P＜0.01).Metabolic profiles showed that the metabolic distribution of healthy rats was significantly separated from that of model rats,and the treatment group was in the middle of the two groups.From the macro-metabolic point of view,the metabolism of model rats changed dramatically.The Ermiao power had a good intervention effect on rheumatoid arthritis.Thirteen biomarkers related to rheumatoid arthritis were identified by database matching,including linolenic acid,arachidonic acid,5,6-EET,alpha-lactose,sucrose,trehalose,prostaglandins and leukotriene C4.It involved linoleic acid metabolism,arachidonic acid metabolism,starch and galactose metabolism and sphingolipid metabolism.Conclusions The Ermiao power has significant therapeutic effect on rheumatoid arthritis rats.Regulation of the linoleic acid metabolism,arachidonic acid metabolism,starch and galactose metabolism may be the mechanism of its treatment of rheumatoid arthritis.

Objective: To understand the proper handwashing behavior of preschool children and primary school students in Beijing, and to analyze associated family factors to provide reference for further health intervention related to handwashing. Methods: From November to December 2020, parents of 36 kindergartens and 18 primary schools in 9 districts of Beijing were investigated online by using a self designed questionnaire with questionnaire star software. The contents of the survey included the basic situation of children and their families, parents correct knowledge of the prevention of novel coronavirus pneumonia, their perception of the epidemic risk, the provision of handwashing guidance for children, and children s handwashing behavior. Results: The proportion of proper handwashing of preschool children was 70.2%, which was higher than that of primary school students (61.9%) ( χ 2=57.63, P <0.01). The proportion of parents of preschool children who correctly knew handwashing related knowledge (36.2%, 33.4%), had low perception of epidemic risk (28.9%, 25.4%), and provided handwashing guidance (99.1%, 97.9%) was higher than that of parents of primary school students, and the differences were statistically significant ( χ 2=6.72, 22.84, 18.68, P <0.05). But the proportion of parents of preschool children who had high self efficacy (75.7%, 78.2%)was lower compared to parents of primary school students( χ 2=6.43, P =0.04). Multivariate regression results showed that whether preschool children or primary school students, urban areas and parents had high self efficacy, low risk perception, and provided hand washing guidance for children, children were more likely to wash their hands correctly. For preschool children, non only children were 0.79(95% CI =0.69-0.92) times more likely to wash their hands correctly than only children. For primary school students, girls were 1.21(95% CI =1.06- 1.39 ) times more likely to wash their hands correctly than boys, and parents who know knowledge correctly were 1.20(95% CI = 1.04 -1.40) times more likely to know it incorrectly( P <0.05). Conclusion Proper hand washing behavior of preschool children is higher than that of primary school students. Parental awareness of COVID-19 epidemic, handwashing behavior, self efficacy and guidance behavior have effects on the development of children s health behavior. Measures should be taken to enhance parents awareness of infectious diseases and their ability and self efficacy of guiding children in disease prevention.

Objective:To investigate the surgical outcomes of acetabular posterior wall fractures in patients aged 50 and above.Methods:A retrospective study was conducted to analyze the clinical data of 67 patients with acetabular posterior wall fracture who had been treated through the Kocher-Langenbeck approach and fully followed up from August 2003 to November 2021. There were 54 males and 13 females, aged 59.0 (54.0, 63.0) years. The time from injury to surgery was 8.0 (5.0, 13.0) days. Open reduction and internal fixation was performed for 63 cases and hip arthroplasty for 4 cases by one stage. The operation time, intraoperative bleeding, quality of postoperative fracture reduction, recovery of hip function at the last follow-up, and incidence of complications during the follow-up period were recorded.Results:The operation time for the 67 patients was 90.0 (67.5, 101.3) min, and the intraoperative bleeding 350.0 (300.0, 450.0) mL. According to the Matta criteria, 63 patients with internal fixation achieved anatomical reduction. All the 67 patients were followed up for (112.8±62.4) months. According to the modified Merle d'Aubigné & Postel scoring system, the function of the affected hip was assessed at the last follow-up in the 63 patients with internal fixation as excellent in 56 cases, as good in 3 cases, as fair in 2 cases, and as poor in 2 cases, giving an excellent and good rate of 93.6% (59/63). The prostheses survived in all the 4 patients who underwent one-stage hip replacement, with hip Harris scores of 94, 92, 91, and 93, respectively. Complications included 15 cases (23.8%, 15/63) of heterotopic ossification and 1 case (1.6%, 1/63) of transient sciatic nerve palsy. Femoral head ischemic necrosis and traumatic arthritis occurred in 2 patients (3.2%, 2/63) who had to receive total hip arthroplasty 3 years after surgery.Conclusion:Open reduction and internal fixation is still the main treatment method for acetabular posterior wall fractures in patients aged 50 and above, because it can achieve good clinical outcomes and help the patients recover joint function and quality of life at an early stage.
