Objective To study the clinical features and prognosis of patients with primary BuddChiari syndrome (BCS) caused by hepatic vein thrombosis.Method 16 patients with primary BCS caused by hepatic vein thrombosis treated in our hospital between June 2010 to December 2012 were used as the study group while 132 patients with primary BCS caused by other causes were used as the control group.A retrospective study was then employed to analyze the clinical data of the two groups of patients during hospitalization and on follow-up.The study was censored in June 2013.The median follow-up was 24 months (range,6 months to 36 months).The difference in quantitative data between the 2 groups were analyzed using the independent-samples t test and the Wilcoxon W rank sum test,and the difference in qualitative data were analyzed using the Chi-square test and the Fisher's exact test.The survival rates and recurrence rates were calculated using the Kaplan-Meier method.Result The study group was significantly lower than the control group in age,duration of symptoms,albumin level,diameter of spleen and survival rate,but it was significantly higher in the proportion of patients with ascites,average hospitalization time,alanine transaminase,aspartate aminotransferase,total bilirubin,carbohydrate antigen-125 and recurrence rate after percutaneous transluminal angioplasty.The differences were significant (P ＜ 0.05).The Rotterdam BCS prognosis grades of the study group were:9 patients grade Ⅱ and 7 patients grade Ⅲ.In the control group,there were 65 patients with grade Ⅰ,51 patients with grade Ⅱ,and 16 patients with grade Ⅲ.The prognosis grade of the study group was significantly higher than the control group (P ＜ 0.05).Conclusion When compared to the patients with BCS due to other causes,patients with BCS caused by hepatic vein thrombosis were more common in the young,most of them were diagnosed in the acute period,they had worse clinical outcomes and had more severe clinical symptoms and liver damage.

Objective To investigated the serum level of carcinoma antigen 125 (CA-125) and its clinical significance in patients with Budd-Chiari syndrome.Methods We reviewed medical records and laboratory tests of patients with BCS first diagnosed in our hospital between August 2011 and April 2013.235 patients were included as experiment group,while 120 healthy adult volunteers were randomly selected as control group.The serum level of CA-125 were detected by electrochemilumescence immunization assay in this single-center retrospective control study.Results The average serum level of CA-125 in experiment group is higher than that of control group [(147.9 ±246.6) kU/L vs (16.0 ±7.2) kU/L,P ＜0.001].In experiment group,the relative coefficient for serum CA-125 with ascites,alanine aminotransferase,aspartate aminotransferase,albumin and Rotterdam BCS scores was 0.79,0.45,0.29,-0.393 and 0.71,respec tively,P ＜0.001.As of October 2013,we found that the 68 BCS patients with serum CA-125 level 5-fold higher than the upper limit of normal (＞ 175 kU/L) presented much lower survival rates and asymptomatic survival rates than the rest 167 BCS patients after intervention therapy:(95.6％ and 79.8％) vs (98.8％ and 92.0％),P ＜ 0.05.Conclusions The serum level of CA-125 in BCS patients have positive correlation with ascites volume,liver injury degree and Rotterdam BCS scores.Serum CA-125 evaluation appears to be a valuable examination option in BCS as CA-125 levels negatively correlate with worse prognosis,thus could be applied as an efficient tool for prognostication.

OBJECTIVETo explore the associated risk factors of metabolic syndrome in Jiangsu province, China.

METHODSUsing identical protocol and questionnaire, an epidemiological study was carried out in a population of 5888 adults in 12 counties in Jiangsu. Anthropometric test and blood sampling were conducted at the time of interview. IDF (2005) was used as the diagnostic criteria of metabolic syndrome . The prevalence and age-standardized prevalence of metabolic syndrome were calculated. Univariate and multivariate logistic regression model were used to identify associated risk factors.

RESULTSThe prevalence and age-standardized prevalence of metabolic syndrome in Jiangsu were 19.07% (11.10% in males and 25.72% in females) and 17.48% (11.49% in males, 22.86 % in females), respectively. Among the potential risk factors of metabolic syndrome as gender, age, education level, occupation, income, physical activity, smoking, alcohol drinking, disease family history, data from univariate and multivariate logistic regression analyses suggested that gender (OR = 1.91), age (OR = 1.15), physical inactivity (OR = 1.94), with hypertension family history (OR = 1.99) and with obesity family history (OR = 6.24) could significantly increase the risk of disease development.

CONCLUSIONMetabolic syndrome has become a significant public health problem among the adults in Jiangsu province.

OBJECTIVETo discuss the characteristics and operative selection of far lateral lumbar disc herniation (FLLDH).

METHODSTwenty-three cases of FLLDH, 14 were foraminal, and 9 were extraforaminal lumbar disc herniation. Of the 23 cases, low back pain was observed in 8 cases (31%), severe lower leg pain in 21 cases (91%) and Lasegue sign in 10 cases (43%). CT and MRI showed the protruded disc in and outside of the foramen clearly. Three surgical procedures were performed, including hemilaminotomy with medial facetectomy, facetectomy with pedicle screw fixation and fusion with posteolateral bone grafting, and the transmuscular approaches.

RESULTSTwenty-two cases were followed up for an average of 3.6 years. According to the Macnab criteria, 15 patients achieved excellent results, good 4, fair 3 and poor 0. Excellent and good rate was 86%.

CONCLUSIONSThe symptoms and signs of FLLDH mainly result from injury of upper nerve segments with the dominant symptom of severe lower leg pain. CT and MRI appearance are not only sensitive but also specific for the diagnosis of FLLDH. In foraminal lumbar disc herniation, the hemilaminotomy with medial facetectomy is recommended. While in extraforaminal lumbar disc herniation, either facetectomy with pedicle screw fixation and fusion with posterolateral bone grafting or transmuscular approaches for removal of nucleus pulposus can be chosen. Microendoscopic discectomy is a new, safe and efficient method for the disease, however, a skillful microendoscopic technique should be mastered prior.

Danggui, Agelicae Sinensis Radix, is a widely used Chinese herb to enrich blood, but its quality cannot be effectively assessed by the known chemical markers such as ferulic acid, ligustilide, polysaccharides, etc. A new bioassay was therefore developed to quantify the Enrich-Blood Bioactivity (EBB) for the quality assessment of Danggui raw materials. Danggui sample was first extracted with ethanol and water, respectively. Then the ethanolic extract and water extract were mixed as a test sample to quantify the amount of EBB by mice experiment. The blood deficiency mode in mice was developed by intraperitoneal injecting cyclophospharmide and phenylhdrazine hydrochloride. The quantity of red blood cell was chosen as EBB marker. Cyclosporine A was chosen as a control substance. EBB in analytes was quantified by the amount reaction of parallel line analysis (3, 3') method. The results indicated that the reliability test for quantifying EBB was passed through and the measured value was valid. The analytes showed the significant EBB (P < 0.05). The correlation coefficient was 0.9984 (n=5) between the amount of cyclosporine A (0.035-0.56 g x kg(-1)) and the increased number of red blood cell. The relative standard deviation (RSY) on the amount of EBB was estimated to be 6.15% (n = 6) by six replicated tests, and the confidence limit rate was 26.68% (n = 6). Five Danggui samples, which were collected from different cultivation areas with various morphological characters, showed the variety of EBB in the range of 21.95-44.16 U x g(-1). It is concluded that the developed method is accurate to quantify the EBB of Danggui raw materials, and is therefore suitable to assess its quality.

OBJECTIVETo identify related factors of job burnout in Shanghai employees.

METHODSFour hundred fifty-six employees in Shanghai were investigated in this study. Self-administered questionnaires were used to assess job burnout and job stress, based on Maslach Burnout Inventory and the Job Demand-Control model as well as Effort-Reward Imbalance Model. Hierarchical linear regression was employed to analyze the relationship of job burnout to personal characteristics and job stress.

RESULTSThe indexes of three dimensions of job burnout were emotional exhaustion 19.70 +/- 8.92, depersonalization 11.95 +/- 4.45 and reduced personal accomplishment 28.10 +/- 10.08. Job stress was found to be affected differently in three dimensions of job burnout. Job demand, effort and over-commitment had positive impact on emotional exhaustion. Job control had a negative association with emotional exhaustion. There were significant relationship between depersonalization and age, sex and education of employees. Job control, reward and over-commitment affected the index of depersonalization. Education level and social support increased personal accomplishment index.

CONCLUSIONIt is necessary to reduce job stress and care about personal characteristics in preventing job burnout.

OBJECTIVEIn this study, a growing rat model of zinc deficiency was established to investigate the effect of zinc deficiency on intestinal mucosal morphology and digestive enzyme activity as well as to provide a scientific basis for zinc supplementation therapy in patients with diarrhea.

METHODThree-week-old weaned Sprague-Dawley male rats (n = 30) were randomly divided into 3 groups with 10 in each: rats in the control group (ZA) were fed with a normal diet containing 30 µg/g zinc; rats in the zinc deficient group (ZD) were fed with a zinc-deficient diet containing 0.4 µg/g zinc (refer to AIN-76 formula); and rats in the paired fed group (PF) were fed with a normal diet, but the food intake was limited to intake of rats in ZD group in the previous day. All rats were provided with deionized water for drinking. Their body weight was measured and the food intake during the previous day was recorded early in the morning of the following day. Symptoms of zinc deficiency, such as anorexia, diarrhea, dermatitis, and growth retardation, were observed. Two weeks later, the rats were sacrificed and serum zinc concentration was measured. Jejunal mucosa was taken for biopsy and was stained with hematoxylin and eosin (HE). The height ratio of the jejunal mucosal villi and crypts was measured. In addition, the activity of lactase in the jejunal mucosal brush border, γ-glutamyl peptidase (GGT), and aminopeptidase N (APN) were measured.

RESULTThe average weight of the rats in the ZA, ZD, and PF groups at the beginning of the experiment was (67.4 ± 5.3) g, (64.7 ± 4.8) g, and (66.5 ± 4.1) g, respectively, and the average daily food intake was (11.2 ± 1.0) g, (11.6 ± 1.6) g, and (11.2 ± 1.4) g, respectively. The intergroup differences were not significant. On the 7(th) day of experiment, no significant differences in average food intake were observed between the ZD group and the ZA and PF groups, but the average body weight in the ZD group was significantly lower than that in the ZA and PF groups (P < 0.01). At the end of the experiment (2 weeks), the average weight in the ZD group (112.0 ± 11.5) g was significantly lower than that in the ZA (164.0 ± 15.9) g and PF groups (137.5 ± 16.2) g. The average food intake in the ZD group (13.4 ± 5.1) g was significantly lower than that in the ZA group (18.2 ± 2.4) g (P < 0.01). Serum zinc level in the ZD group (733 ± 231) µg/L was significantly lower than that in the ZA (1553 ± 159) µg/L and PF groups (1457 ± 216) µg/L (P < 0.01). The height ratio of jejunal mucosa villus and crypt in the ZA, ZD, and PF groups was 2.98 ± 0.5, 2.77 ± 0.5, and 2.81 ± 0.7, respectively, and lactase activity was (26.1 ± 15.0) U/mg, (27.4 ± 12.8) U/mg, and (40.8 ± 18.5) U/mg, respectively, without significant intergroup differences. The GGT activity in the jejunal mucosa in the ZD group (12.7 ± 6.5) U/g was significantly lower than that in the ZA (19.1 ± 10.4) U/g and PF groups (18.5 ± 7.7) U/g, but the difference was not significant. The activity of APN in the jejunal mucosa in the ZD group (25.5 ± 7.5) U/g was significantly lower than that in the ZA (48.7 ± 16.8) U/g and PF groups (43.9 ± 14.5) U/g (P < 0.01).

CONCLUSIONZinc deficiency can cause loss of appetite, weight loss, and decreased activity of peptidase in the jejunal mucosal brush border. Zinc deficiency has little effect on the height ratio of the villus and crypt and lactase activity, thereby indicating that zinc deficiency may first affect protein digestion and absorption.

Objective To explore the effect of meteorological factors on the incidence of hand foot and mouth disease (HFMD) in Jiangyin City. Methods The distributed lag non-linear model (DLNM) was used to estimate the delayed and cumulative effects of meteorological factors on incidence of HFMD in Jiangyin from 2012 to 2017. Results A total of 21 791 HFMD cases were reported in Jiangyin City during 2012-2017. We observed significant correlations between the daily incidence of HFMD and daily mean temperature (rs=0.402, P<0.001), daily mean pressure (rs=-0.453, P<0.001), and daily mean relative humidity (rs=0.075, P<0.001), respectively. It was indicated that the maximum cumulative effect of daily mean temperature on the incidence of HFMD was 11 ℃ (RR=1.473, 95% CI: 1.99-1.974), and the impact on the onset of HFMD was acute and hightest at the first day (RR=1.090, 95% CI: 1.045-1.136). The cumulative effect on incidence of HFMD was highest at 85% daily relative humidity (RR=1.346, 95% CI: 1.154-1.571), and the impact on HFMD peaked on the 6th day (RR=1.023，95% CI: 1.015-1.031); The maximum cumulative effect of daily mean pressure with the incidence of HFMD was 1010.0 hpa (RR=1.221, 95% CI: 1.020-1.463), but no lag effect was observed at this level. Conclusions Meteorological factors have significant impact on the incidence of HFMD in Jiangyin City, and the effects of temperature and humidity are lagged.
