The effects of Wumeiwan (WMW) on TNF-alpha, IL-6, IL-8, IL-10 and NF-kappaBp65 in rats with ulcerative colitis (UC) were investigated, the curative effectiveness of WMW vs salicylazosulfapyridine (SASP) was compared, and the action mechanism was analyzed. Fifty-Six Sprague-Dawley (SD) rats were randomly divided into four groups (n=14 in each group, with equal ratio of male and female): normal control group, model group, SASP group, and WMW group. Except normal control group, the rat UC models in the remaining three groups were established using the method of 2.4-dinitrochlorobenzene (DNCB) immunization and acetic acid local enema. The rats in model group, SASP group, and WMW group were treated with distilled water, SASP, and WMW respectively. The changes in the symptoms and signs were observed, and levels of IL-6, IL-8, TNF-alpha, IL-10 and the expression of NF-kappaBp65 in the colonic tissues were statistically analyzed. The results showed that the levels of IL-6, IL-8, and TNF-alpha were significantly increased (P<0.01), while those of IL-10 significantly reduced (P<0.01) after establishment of rat UC models as compared with normal control group. The levels of IL-6, IL-8, and TNF-alpha were obviously lower, but the level of IL-10 was obviously higher in WMW and SASP groups than those in model group (P<0.05). The levels of IL-6, IL-8, and TNF-alpha were lower, while the level of IL-10 was higher in WMW group than in SASP group. NF-kappaBp65 was expressed negatively or weakly in normal colonic tissues. The positive expression rate of NF-kappaBp65 in WMW group and SASP group was obviously lower than in model group (P<0.01), and there was significant difference between WMW group and SASP group (P<0.05). It was concluded that rat UC model was established successfully. WMW could up-regulate the expression of IL-10, down-regulate the expression of TNF-alpha, IL-6, IL-8, and inhibit the NF-kappaBp65 activity to adjust immune function, indicating WMW had better curative effects on UC in rats.

Objective To explore the approach and early effects of endovascular stent-graft deployment in the treatment of portal stenosis of cancerous thrombus.Methods Six cases with portal vein stenosis of cancerous thrombus,which caused by primary hepatic carcinoma(5 cases)and eholangiocarcinoma(1 case)and the severity of stenosis showed on contrast enhanced CT were more than 75% or occluded,were performed percutaneous transhepatie or transsplenic portography.FLUENCY~(TM) endovascular stent-graft(10 mm diameter)was placed at the position of stenosis after gastroesophageal varices embolization.Portal pressure was measured pre-and post-deployment.Results Stents were successfully placed in all patients.The average portal pressure decreased from 50.7 cm H_2O(1 cm H_2O = 0.098 kPa)to 41.3 cm H_2O after endovascular stent-graft deployment.The restenosis were found in 2 cases after one month.Haematemesis and refractory aseites appeared in one case respectively,the other 4 cases showed no significant symptoms above caused by portal hypertension.Conclusion It is safe and feasible for endovaseular stent-graft deployment in the treatment of portal stenosis of cancerous thrombus.Selecting the suitable indications,the symptoms of portal hypertension can be controlled effectively.

Objective To determine the bowel habits and its perceptions in the general population of Guangdong province. Methods Random clustered sampling involving permanent inhabitants aged 18-80 year was carried out under stratification of urban and suburban areas in Guangdong province. Questionnaire included the items on the characteristics of people being selected and their bowel habits. Results A total of 4103 residents (male 1878, female 2225) were investigated. Mean age among the responders was 42.81 ± 14.13 year. Among 4056 subjects (missing =47 ), 2972 subjects (73.3%) reported daily defecation, and 3951 subjects (97.4%) reported stool frequency between 3 times per week and three times per day. Two hundred and seventy subjects (6.6%) reported abnormal bowel habits by themselves. The stool frequency (OR=2.03, 95% CI:1.54-2.67) , forms of stool (OR=2.75, 95% CI: 2.35-3.22) and straining (OR=3.56, 95% CI:2.49-5.11) were significantly associated with self-reported abnormal bowel habits. Among 3949 subjects (missing= 154), 644 (16.3%) were defined as having abnormal bowel habits according to Rome Ⅱ criteria. There was poor agreement between self-reported abnormal bowel habits and that defined by Rome Ⅱ criteria (Kappa=0.312). Conclusion It seemed to be appropriate that the normal stool frequency was defined as bowel movements between 3 times per week and three times per day in the general population. The prevalence of self-reported abnormal bowel habits was lower than that defined by Rome Ⅱ criteria and the agreement between these two definitions was poor.

Objective To investigate the clinical efficacy of modified Banxia Houpu Decoction plus Deanxit for the treatment of cancer-related depression(CRD)of phlegm blended with qi type.Methods Sixty-four CRD patients with phlegm blended with qi type were randomly divided into the treatment group and the control group,with 32 patients in each group.The control group was given oral use of Deanxit,and the treatment group was treated with modified Banxia Houpu Decoction plus Deanxit orally.The course of treatment covered 4 weeks.The changes of Karnofsky Performance Status(KPS)scores,self-rating depression scale(SDS)scores,and traditional Chinese medicine(TCM)syndrome scores in the two groups were observed before and after the treatment.Moreover,the efficacy for improving KPS scores and TCM syndrome efficacy in the two groups were also evaluated.Results(1)After 4 weeks of treatment,the total effective rate for improving KPS scores in the treatment group was 90.63%(29/32),and that in the control group was 78.13%(25/32).The intergroup comparison showed that the efficacy for improving KPS scores in the treatment group was significantly superior to that in the control group(P＜0.01).(2)In terms of the efficacy of TCM syndromes,after 4 weeks of treatment,the total effective rate for improving TCM syndrome scores in the treatment group was 87.50%(28/32),and that in the control group was 40.63%(13/32),and the efficacy of TCM syndromes in the treatment group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the KPS scores in the treatment group were significantly increased compared with those before treatment(P＜0.05),and the KPS scores in the control group tended to increase compared with those before treatment,but the difference was not statistically significant(P＞0.05).The intergroup comparison showed that the effect on increasing KPS scores in the treatment group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the SDS scores in the two groups were lower than those before treatment(P＜0.05),and the effect on lowering SDS scores in the treatment group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the TCM syndrome scores of the two groups were lower than those before treatment(P＜0.05),and the effect on lowering TCM syndrome scores in the treatment group was significantly superior to that in the control group(P＜0.05).Conclusion Modified Banxia Houpu Decoction plus Deanxit exerts certain effect for the treatment of CRD of phlegm blended with qi type.The combined therapy can effectively improve the depression mood and quality of life of the patients,and its efficacy is superior to that of Deanxit alone.

Objective To assess the fluorine (F), arsenic (As) and selenium (Se) levels in hair of residents from the fluorosis area of Zhaotong and provide reference basis for the evaluation of the health status of populations in fluorosis areas as well as the prevention and control of fluorosis in Zhaotong. Methods Sixty-five hair samples were collected in fluorosis areas(Zhenxiong, Weixin County), including. 41 samples from 6 endemic townships and 24 samples from a non-endemic township. Fluorine content in hair was determined by combustion- hydrolysis-ion selective electrode method. Arsenic and selenium contents in hair were determined by atom- fluorescence method. Results The average contents of hair fluorine, arsenic and selenium contents were (15.1807±15.2397), (2.1806±1.9601), (2.3162±2.4535)mg/kg in the 41 patients with fluorosis and were (18.7703±17.1067), 0.3283±0.2466), (1.2805±0.6970) mg/kg in the 24 inhabitants (control). The difference of fluorine content in hair between patients in fluorosis and control inhabitants was not statistically significant (P 0.05), but the difference in arsenic and selenium content was statistically significant (P<0.05). Conclusions Mild arsenic pollution exists in Zhaotong fluorosis areas, which aggravates the prevalence of fluorosis. Food roasted with blended coal contains high fluorine. Meanwhile it may bring in the supplement of selenium for the inhabitants in Zhaotong fluorosis areas.

OBJECTIVETo summarize the clinical changing characters of the clinical markers after interferon treatment in chronic hepatitis B (CHB) and make out practical indexes to predict the effect.

METHODS150 CHB patients were randomly divided into two groups: therapeutic group (90) and control group (60) in the prospective controlled trial. The levels of endogenous interferon before treatment, interferon antibody at the end of the second month and fourth month after treatment, alanine aminotransferase (ALT) and HBV DNA in the serum were detected. Then the data was analysed to find out indexes for predicting the effect.

RESULTS(1) The clearance rate of HBeAg had no significant difference in age except for 20 - 30 and 30 - 40 (t > 2.331 2, P < 0.01). (2) It was more effective if ALT level was higher than 400 U/L before treatment and it decreased more than 50% two months after treatment. (3) The patients whose HBV DNA was negative (dot hybridization) or less than 10(6) copies/ml before treatment had higher rate of HBeAg clearance. (4) There was no effect on patients whose interferon antibody turned positive at the end of the second month. (5)A predictive method of comprehensive factors was made out, whose sensitivity, specificity, and accuracy were 80%, 100% and 90%, respectively.

CONCLUSIONThe clinical characters of these Chinese patients are different from those of the westerners and the effects of interferon have close relation to the levels of ALT, HBV DNA and interferon antibody.

BACKGROUNDThe hybrid procedure for coronary heart disease combines minimally invasive coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) and is an alternative to revascularization treatment. We sought to assess the predictive value of four risk-stratification models for risk assessment of major adverse cardiac and cerebrovascular events (MACCE) in patients with multivessel disease undergoing hybrid coronary revascularization.

METHODSThe data of 120 patients were retrospectively collected and the SYNTAX score, EuroSCORE, SinoSCORE and the Global Risk Classification (GRC) calculated for each patient. The outcomes of interest were 2.7-year incidences of MACCE, including death, myocardial infarction, stroke, and any-vessel revascularization.

RESULTSDuring a mean of 2.7-year follow-up, actuarial survival was 99.17%, and no myocardial infarctions occurred. The discriminatory power (area under curve (AUC)) of the SYNTAX score, EuroSCORE, SinoSCORE and GRC for 2.7-year MACCE was 0.60 (95% confidence interval 0.42 - 0.77), 0.65 (0.47 - 0.82), 0.57 (0.39 - 0.75) and 0.65 (0.46 - 0.83), respectively. The calibration characteristics of the SYNTAX score, EuroSCORE, SinoSCORE and GRC were 3.92 (P = 0.86), 5.39 (P = 0.37), 13.81 (P = 0.32) and 0.02 (P = 0.89), respectively.

CONCLUSIONSIn patients with multivessel disease undergoing a hybrid procedure, the SYNTAX score, EuroSCORE, SinoSCORE and GRC were inaccurate in predicting MACCE. Modifying risk-stratification models to improve the predictive value for a hybrid procedure is needed.

OBJECTIVETo propose a novel surgical procedure for refractory constipation, namely Jinling procedure, and to explore its safety and efficacy through long-term follow-up.

METHODSA total of 614 patients with refractory constipation were admitted to the Department of General Surgery between February 2000 and June 2011. Five hundred and fifty-four patients received Jinling procedure and were included in this study. The general clinical data, complications after Jinling procedure, gastrointestinal quality of life index (GIQLI), Wexner constipation scale and satisfaction rate during follow-up were collected.

RESULTSNo operation-associated death occurred. Increased bowel movement frequency was observed during the perioperative period. Temporary difficulty in urination occurred in 24.5% of the patients. Other complications included small bowel obstruction (9.6%), anastomotic bleeding (8.1%), anastomotic leakage (3.1%), sexual dysfunction (3.1%), and wound infection (3.1%). Most postoperative complications were managed conservatively. The most recent follow-up was on August 2011, and the follow-up rate was 100%, 88.8%, 75.1%, 56.3% at 3, 6, 12, and 24 months after surgery. GIQLI temporarily increased from 78.1±9.4 preoperatively to 92.0±9.5 at 3 months follow-up, but continued to decrease during the follow-up at the 6 months (48.4±14.1), 12 months (21.0±4.3), and 24 months (20.0±3.4). Wexner constipation scale decreased from 19.9±4.3 preoperatively to 8.4±2.1 at 3 months follow-up (P<0.01). The low Wexner scale sustained until 24 months after operation. The satisfaction rate at the 3, 6,12 and 24 months follow-up was 78.1%, 91.1%, 94.2% and 94.6%, respectively.

CONCLUSIONJinling procedure provides refractory constipation patients with a novel, safe and effective surgical option.

OBJECTIVETo determine the clinical value of 24 h double-probe pH-metry for the diagnosis and treatment of laryngopharyngeal reflux (LPR).

METHODSAccording to the pH-metry results (whether the reflux events record in the upper esophagus is more than 6.9), patients of refractory pharyngolaryngitis were divided into LPR and control groups (each of 17 cases). All patients treated with anti-acid therapy and conventional pharyngo-laryngitis therapy. Correlation between pH-metry and the reflux symptom index (RSI), the reflux symptom index (RFI) were analyzed. Changes of the RSI and RFI in different group were calculated in post-treatment.

RESULTSIn the LPR group, the median reflux events of the upright time were higher than the supine time (Z = -3.62, P < 0.01), but the difference was not discovered in the control group (Z = -0.60, P > 0.05). There was no statistical difference between RSI, RSI and RFS with pH-metry, and with moderate concordance (k were 0.47, 0.53, P < 0.01, respectively). Compared to pre-treatment, the RSI and RFI were decreased both in LPR group and control group, Amplitude decreased in LPR group significantly higher than the control groups, with statistical difference (t were 3.74, 3.01, P < 0.01, respectively).

CONCLUSIONThe 24 h double-probe pH-metry is significant for the anti-acid therapy of LPR.
