Objective To investigate the effect of mesalazine on the expression of TNF-α, IL-6, IL-17 and intestinal barrier function in patients with ulcerative colitis. Methods 76 patients with UC from January 2015 to April 2016 in The Fifth Central Hospital of Tianjin were collected and randomly divided into control group and observation group with 38 cases in each group. After admission were given maintenance of water and electrolyte, basic acid-base balance and nutritional support treatment, and the control group were treated with conventional drug sulfasalazine (SASP) treatment, two tablets each time, four times once day, four weeks for each course, the observation group was treated with mesalazine, four tablets each time, three times once day, four weeks each course of treatment. The levels of TNF-α, IL-6, IL-17, L/M and Baron endoscopic scores in the two groups were observed after two courses of treatment. The efficacy and side effects of the two groups were compared. Results No dropout or dropout cases in this study, two groups after the treatment of TNF-α, IL-6, IL-17, L/M, Baron scores were significantly decreased (P<0.05), but the observation group after treatment the above indexes were all significantly lower than the control group (P<0.05), the total effective rate of the observation group was 89.47%(34/38) higher than that of the control group 71.05%(21/38), the adverse reaction rate of 13.16% (5/38) was lower than that in the control group 34.21% (13/38), the differences were statistically significant(P<0.05). Conclusion Compared with conventional drug SASP, the effect of on the expression of TNF-α, IL-6 and IL-17 in serum of patients with UC and the improvement of intestinal barrier function can be effectively suppressed, which has the advantages of clinical efficacy and low adverse reaction rate.

Objective To investigate the impact of thyrotropic hormone (TSH) on recurrence rate of common bile duct stone (CBDS).Methods The clinical data of 268 cases of primary or recurrent CBDS undergoing surgery was analyzed.According to whether screening preoperative TSH level routinely,we assigned the patients into two groups,unchecked group with 171 cases and screened group with 97 cases.The postoperative recurrence rates in 36 months between two groups were compared.Results The recurrence rates of unchecked group and screened group were 3.5％,12.9％,16.9％ and 0.0％,5.2％,8.2％ respectively in 12-,24-,36-months,there was statistically significant difference between two groups (x2 =4.029,P ＜ 0.05).In unchecked group,patients ≥ 60 years had a significant higher recurrence rate than ＜ 60 years patients (x2 =6.485,P ＜ 0.05).In screened group,there was no statistically significant difference between ≥60 and ＜ 60 patients (x2 =0.142,P ＞ 0.05).In those 34 patients with a high TSH level in the screened group,normalizing the level from (6.23 ± 1.44) μIU/ml to (2.91 ±0.74) μIU/ml by oral intake of thyroid hormone postoperatively,led to the recurrence rates of 0％,5.9％,8.8％ in 12-,24-,36-months,which was not significantly different from those with normal TSH (x2 =0.022,P ＞ 0.05).And that,there was not statistically different between the young and elder patients in those 34 cases for the 12-,24-,36-month recurrence rates (x2 =0.086,P ＞ 0.05).Conclusions Some CBDS patients may be with high level of TSH.Normalizing TSH level may be conducive to a reduced postoperative recurrence rate of CBDS.

BACKGROUND: Visual-motor integration (VMI) test was introduced into China in the 1970s and 1990s and widely used for evaluation and identification of problems in intellectual development and learning ability in children due to its good applicability without limitations by language and cultural background.OBJECTIVE: To assess the value of developmental test of VMI in children with hearing handicap, and evaluate its practical feasibility in largescale screening of intelligence problems in these children by comparing its reliability and validity with the norms of children in Shaanxi Province and the USA.DESIGN: A controlled correlation and multiple stepwise regression analysis with randomized cluster sampling.SETTING: Neurological Department of the First Hospital Affiliated to Medical College of Xi' an Jiaotong University.PARTICIPANTS: From January 1998 to December 2000, 638 children under 18 years of age with hearing handicaps were chosen from 6 schools of deaf-mutes in Xi'an City, Xianyang City, Chang'an County, Huxian County,and Lintong County in Shaanxi Province. Another 43 children with hearing handicap including 23 male and 20 female children aged (11.62±1.98) years were selected randomly for EEG and brain electrical activity mapping (BEAM) examination, who had a mean development quotient of VMI of 86.60±15.68. The children were divided by the development quotient into two groups, namely those with development quotient ＜ 86.6 (n=20) and those with development quotient ≥ 86.6 (n=23). METHODS: ① The VMI test was performed in accordance with the Fourth edition of VMI Manual by Beery K.E. The test was terminated when the testee failed to correctly copy three consecutive geometrical figures without time limit. The scale score varied from 0 to 27. ② The reliability test included split-half reliability test in which the items were split into two parts according to odd-even number, re-test reliability that tested the same group of children again in two months and inter-examiner reliability in which two examiners were asked to grade the same test paper.③ The validity test included structural and correlation validity test. Three well-revised and already established norms of scales in China, including Hiskey- Nebraska test of learning aptitude (H-NTLA), performance scale of Wechsler intelligent scale for children (PS-WISC) and Combined Raven's test (CRT), have been chosen as the structure validity criteria. The performance IQ of PS-WISC, learning quotient of H-NTLA, percentile rank of CRT and standard score of VMI were taken respectively for each test in this study.Academic achievements and teachers' and parent's rating were used as the validity correlation criteria. During the administration procedure, a card describing the requirements in detail were presented to the deaf children with reading capacity, while for those too young to read, the teacher was asked to help translate the requirements using standard sign language, but no any hints or clues in relation with the test contents were given. ④ The test did not start until the subjects fully understood the requirement (7314/F/W DYD-300A).EEG recording was performed with the leads deposited according to the international standard 10/20 lead system. Routine EEG had been recorded at least 30 minutes for visual assessment, and stable and representative waves for 120 seconds free of biases or inferences were recorded using unipolar lead from the subjects at rest with the eyes closed and stored in computer.Experienced EEG experts were asked to select the most representative waves of 20 seconds in a double-blind manner to compute the absolute power spectrum of the brain wave.MAIN OUTCOME MEASURES: Reliability and validity of VMI test,relationship between VMI ability and cerebral electrophysiological changes.RESULTS: Totally 638 children under 18 years old with hearing handicap were involved, of whom 72 were eliminated because of lack of data, congenital disease or central nervous system diseases. Finally 566 cases were available for analysis, including 346 male and 220 female children with an average age of (12±3) years. ① The reliability of VMI reached an average of 0.92, varying from 0.63 to 0.99 in each group. The equivalent age corresponding to the scores of the VMI test norm established for the 566 healthy deaf children was lower by an average of (1.79±0.9) years than the equivalent age in the norms of the normal children in Shaanxi Province delayed and USA. ② The standard score of VMI test showed the highest correlation coefficient of 0.661 0 with the learning quotient of H-NTLA, while the correlation with PS-WISC and CRT were 0.357 6 and 0.517 4, respectively.③ Children with higher VMI score showed more powerful absolute spectrum among frequency rangesδ,θ,αl and total power spectrum in the central, parietal and occipital regions of the left hemisphere, respectively.CONCLUSION: VMI test can efficiently reflect the development status of visual-motor integration or intelligence of the school-age deaf children and represent the level of central EEG activity.

BACKGROUND: Chemotherapy has been the very important adjunctive treatment for the patients with large intestine cancer. However, obvious individual difference exists in the sensitivity of the patients to the chemotherapeutic drugs, and the difference is related with the age and sex of the patients or not?OBJECTIVE: To make an exploratory discussion of that whether the difference of the sensitivity of chemotherapeutic drugs exists in different ages and different sexes of the patients with epidemiological investigation of the tumor cell survival rate.DESIGN: Controlled experimental study based on pathological samples.SETTING: General surgery department of an affiliated hospital of a medical college.PARTICIPANTS: Tumor cell samples of 169 cases of colorectal cancer tissue obtained from patients with colorectal cancer at the Department of General Surgery of the affiliated hospital of North Sichuan Medical College during the period from January 2001 to January 2003 were involved as subjects. The patients, 97 males and 72 females, were made a definite diagnosis of the large intestine cancer by operation and pathological examination and have not been treated with chemotherapy before operation.METHODS: The sensitivity of chemotherapy drugs were measured on the survival tumor specimens of 169 patients with colorectal carcinoma with Methyl thiazolyl tetrazolium(MTT) test method in vitro. The differences of different ages and different sexes were analyzed in patients.MAIN OUTCOME MEASURES: The absorbance values of tumor cell 72hours after treatment with chemotherapeutic drugs.RESULTS: There was no obvious significance of the tumor' s sensitivity to chemotherapeutic agents in different ages and sexes in patients with colorectal cancer( P ＞ 0.05).ONCLUSION: The individual difference of sensitivity for chemotherapeutic agents in patients with colorectal cancer is not related with the age and gender, needless to consider age and gender in selecting chemotherapeutic agents for different individuls.

ObjectiveTo evaluate the modified Barcelona Clinic Liver Cancer (BCLC) staging system for predictability of intrahepatic recurrence for patients with hepatocellular carcinoma (HCC) following curative hepatectomy.MethodsA retrospective study was conducted on 197 consecutive patients with HCC who underwent curative hepatectomy in our department from Jan.2008 to Jan.2011.Univariate and multivariate analyses using Cox proportional hazard model were used to evaluate possible association between clinicopathologic factors and early postoperative intrahepatic recurrence (ER).Receiver operating characteristics (ROC) analysis with calculation of the area under the curve (AUC),sensitivity,and specificity were applied to define the cutoff point values for possible meaningful continuous variables where appropriate.A comparison between the differences in AUC was used to assess BCLC and a modified BCLC (M-BCLC) staging system for their predictive ability of ER.Risk stratification according to calculated M-BCLC was applied to find differences of ER at various time points after curative hepatectomy.ResultsDuring follow-up,111 patients developed ER.The 6-,9-,12-,18- and 24-month cumulative recurrent rates were 26.9％ (53/197),37.6％ (74/197),45.2％(89/197),53.8％ (106/197) and 56.3％ (111/197),respectively.Multivariate analysis revealed thatthe severity of concomitant cirrhosis,elevated AFP≥185.6 μg/L and BCLC staging were risk factors of ER.A M-BCLC was proposed based on the results of multivariate analysis.The severity of cirrhosis and elevated AFP values were included in the BCLC staging.This M-BCLC exhibited better performance.It predicted at different time points of ER at postoperative 9,12,18 and 24 months to be significantly better with M-BCLC than BCLC using AUC drawn from ROC.No significant difference was found with ER prediction at 6 months.The M-BCLC also demonstrated a ER prediction with AUC of 0.710 (95％ CI,0.630-0.790) and achieved a sensitivity of 83.0％,a specificity of 51.9％as calculated from ROC with M-BCLC≥2.913.Further risk stratification according to the M-BCLC at various cutoff point values revealed the ER occurrence rates amongst the different risk groups to be significantly different when compared with the median ER time (17.9 mons,9.9 mons vs 5.7 mons,x2=25.770,P=0.000,Log-Rank test).ConclusionA modified BCLC staging system based on multivariate analysis improved the predictability of ER following curative hepatectomy for HCC.

Objective To explore the feasibility and validity of laparoscopic choledochotomy and choledochoscopy for treament of patients with acute pancreatitis accompanying commom bile duct stones. Methods A total of 102 patients acute pancreatitis accompanying common bile duct gall stones were treated in our institution between January 2007 and November 2009. Among them, 43 patients underwent laparoscopic choledochotomy and choledochoscopy within 72h after admission entered our study group. They all had a laparscopic cholecystectomy and choleldochotomy and choledochoscopy to retrieve common bile duct stones. Of these, 13 patients undergoing pancreatic capsule incision and peritoneal lavage. Fifty-nine patients undergoing traditional conservative treatment firstly were used as a control group. Of these, 46 were performed laparscopic surgery and choledochotomy after smoothly recovery from pancreatitis. 13 underwent emergency open operation due to complications of pancreatitis. Results In the gastrointestinal function recovery time, amylase recovery time, length of stay and hospitalization cost, there was a significant difference between study group and the control group (P<0.05). Conclusions Our study provides evidence for the good clinical efficacy of early implementation of laparoscopic choledochotomy and choledochoscope for treatment of choledocholithiasis and acute pancreatitis.

Objective To explore the characteristics and influencing factors of cognitive dysfunction in patients with essential tremor (ET).Methods We recruited ET patients diagnosed by the Department of Neurology of the First Affiliated Hospital of Xi`an Jiaotong University and healthy volunteers who matched the ET patients in age, gender and education level for the study.We recorded all the patients` demographic information, tremor degree, and family history based on the family tree.All the participants were tested by MMSE, MoCA, ADL, HAMD and HAMA.Results There were 88 ET patients and 63 normal subjects included in the study.According to MMSE, 31.82％ of the patients had cognitive dysfunctions, with orientation, short-term memory, calculation ability, language skills, retelling, reading comprehension, three-level command and drawing being significantly lower than those of the healthy volunteers (P<0.01);orientation was the most serious damage in cognitive function domain (K=0.624, S=0.726);three-level command was the least serious damage (K=0.274, S=0.319).According to MoCA, 86.36％ of the ET patients had cognitive dysfunction higher than normal people (P<0.05);visual space and execution, clock drawing task, naming, attention, 100-7, language skills, abstract thinking and orientation were significantly lower than normal people (P<0.01);the most serious damage in cognitive function domain was visual space and execution (K=0.651, S=0.786); the least serious damage cognitive function domain was “100-7” (K=0.406, S=0.484). Education level and age affected cognitive dysfunction (P<0.05). ADL scores showed negative correlation with cognitive function (correlation =－0.375 and －0.383, respectively; P<0.001). After the effects of anxiety and depression were excluded, onset age and tremor grading were correlated with cognitive dysfunction (P<0.05). When the above factors were put into binary Logistic regression model, education level was found to be contributed to the model (P<0.05).Conclusion Patients with ET widely suffer from cognitive impairment. Age, education level, daily life disability, age of onset, and tremor degree classification can affect cognitive dysfunction.

ObjectiveTo evaluate the impact of anatomic and non-anatomic liver resection on prognosisofpatientswithsmallhepatocellularcarcinoma( HCC ) usingaMeta-analysis.MethodsLiterature on anatomic versus non-anatomic liver resection for the treatment of small HCC ( ≤5 cm) was retrieved. ResultsFour nonrandomized controlled trials were included consisting of 776 patients:484 undergoing anatomic liver resection and 292 non-anatomic resection.The age ranged from 53.4 to 63.0 years.Male ∶ female ratio was 3.56 ∶ 1.87.1％ patients were Child-Pugh class A.Most patients (94.5％ ) had a single tumor.No significant differences were found conceming the 1,3,and 5 year disease-free survival rate between the two groups.There was no significant difference in overall survival and disease-free survival between the two groups at 1,3,and 5 years.Sensitivity analysis found anatomic resection was superior to non-anatomic resection in 3 year disease free survival rate (OR =0.72,95％ CI:0.52 - 0.99,P =0.04). ConclusionsAnatomic liver resection elevated the 3 year disease free survival rate of patients with small hepatocellular carcinoma when compared with non-anatomic hepatectomy but failed to further elevate long-term disease free survival and overall survival.
