Objective To survey and analyze characteristics of brucellosis epidemic in Weinan city of Shaanxi province for the purpose of setting up prevention and control measures for the disease. Methods According to "The Executing Plan for the Work of Surveying Brucellosis Disease in Shaanxi Province", 35 villages(towns) of designated monitoring locations and 24 villages (towns) of randomized monitoring locations in five countries of Weinan were chosen to survey brucellosis disease. The five countries were Chengcheng, Dali, Heyang, Tongguan and Hancheng. High risk populations with a history of contacting livestock and livestock products aged between 7 and 60 underwent clinical and serology examination[rose bengal plate agglutination test(RBPT) and standard tube agglutination test(SAT)]. All manipulation methods and judging standards were in accord with the "Diagnostic Standard for Brucellosis" (WS 269-2007). Results In the designated monitoring location, a total of 8664 people at high risk were investigated, among whom 1407 people were tested by RBPT test and 27 people were positive,the positive rate was 1.92%(27/1407); 27 people were tested by SAT test and 27 people were positive, the positive rate was 100% (27/27); 25 people were diagnosed and the diagnosis rate was 92.59%(25/27). In the randomized monitoring location, a total of 3464 people at high risk were investigated, among whom 411 people were tested by RBPT test and 3 people were positive, the positive rate was 0.73%(3/411 ), 3 people were tested by SAT test which were all positive and made a definite diagnosis. Twenty-eight new cases were made a definite diagnosis and its incidence was 2.06 in a hundred thousand(28/1 361 618). Conclusions The infection of human brucellosis in Weinan city stays at higher level. The governments should increase input for the monitoring,investigating and disinfecting to prevent the disease from increasing and outspreading.

OBJECTIVETo study the relationship between expression of galectin-3 (Gal-3) and osteopontin (OPN) in occult metastasis in non-small cell lung cancer.

METHODSForty-six patients of non-small cell lung cancer (NSCLC) from January 2006 to October 2007 were selected. There were 28 males and 18 females, aged from 33 to 77 years old. The levels of lung tissues Gal-3 and OPN were detected by RT-PCR, and the levels of blood plasma's were measured by ELISA.

RESULTSThere were 12 patients who had metastasized. In un-metastasis group the Gal-3 and OPN mRNA expression levels were significantly lower than that in metastasis group: mean value were 0.07 +/- 0.17 and 0.17 +/- 0.25 in un-metastasis group, while 0.73 +/- 0.23 and 0.79 +/- 0.24 in metastasis group. Blood plasma levels of Gal-3 (18.8 +/- 7.9) microg/L and OPN (153.5 +/- 63.5) microg/L in NSCLC which were detected from metastasis group were higher than un-metastasis group of (9.2 +/- 5.6) microg/L and (89.2 +/- 24.0) microg/L.

CONCLUSIONSHigh serum levels of Gal-3 and OPN and high expression of Gal-3 and OPN mRNA in NSCLC are closely related to the occurrence and metastasis of NSCLC. They may be indexes of evaluating the occult metastasis in NSCLC.

OBJECTIVETo evaluate the feasibility and safety of early chest tube removal after lobectomies for lung diseases.

METHODSA prospective randomized control study was performed with data collected from lobectomies between March 2012 and September 2012. Eligible patients (n = 70) were randomized into two groups; early removal group (removal of chest tube when drainage less than 300 ml/24 h, n = 41) and traditional management group (removal of chest tube when drainage less than 100 ml/24 h, n = 29). Criteria for early removal were established and met before chest tube removal. The volume and character of drainage, time of extracting drainage tube and postoperative hospital stay were measured. All patients received standard care during hospital admission and a follow-up visit was performed after 7 days of discharge from hospital.

RESULTSThere were no differences between two groups with respect to age, sex, comorbidities, or pathologic evaluation of resection specimens. The median volume of drainage within 24 h after surgery was 300 ml and within 48 h was 250 ml, there was significantly different between two groups (Z = -2.059, P = 0.039). Patients undergoing early removal management had a shorter Chest tube duration (44 hours vs. 67 hours, Z = -2.914, P = 0.004) and a shorter postoperative hospital stay (5.0 days vs. 6.0 days, Z = -3.882, P = 0.000). Analysis of data showed no statistically significant differences between the rate of pleural effusions developed, thoracentesis and complications, one week after discharge from hospital.

CONCLUSIONSCompared to the traditional management group (drainage ≤ 100 ml/24 h), early removal of chest tube after lobectomy (drainage ≤ 300 ml/24 h) is feasible and safe. It could result in a shorter hospital stay, and most importantly, reduces morbidity without the added risk of complications.

Leguminous related SSR primers were collected, core primers used for Astragali Radix and Hedysari Radix identification were screened and validated by using molecular marker techniques. 6 core primers were selected from 101 pairs of primers, the molecular weight of PCR products was 100-500 bp, which formed 7-12 electrophoresis bands with 55 amplified loci. The percentage of polymorphic loci was 100%, and the average polymorphism information content was 0.371. According to the results of cluster analysis, obtained core primer could completely distinguish 62 mixture samples of Astragali Radix and Hedysari Radix in similarity coefficient of 0.46. Core primers and the corresponding characteristics from gel electrophoresis were tagged. The results provide identification basis for Astragali Radix and Hedysari Radix.

Objective: To investigate the blood lipid levels and prevalence of dyslipidemia in people with hypertension and diabetes in Henan province. Methods: From April 2016 to April 2017, multi-stage cluster sampling was adopted to investigate 71 285 local residents aged between 35 and 75 from 6 districts and counties in Henan province including Zhongmu county of Zhengzhou city, Huojia county of Xinxiang city, Hualong district of Puyang city, Qi county of Hebi city, Xigong district of Luoyang city, and Wugang city of Pingdingshan city. Blood samples were collected. According to the diagnostic criteria of hypertension and diabetes, the study population was divided into control group (n=29 427), hypertension group (n=21 965), diabetes group (n=8 009) and hypertension-diabetes group (n=11 884). Comparisons on blood lipid levels and dyslipidemia between 4 groups were performed. Results: The total cholesterol (TC) level of all subjects was 4.37 (3.78, 5.05) mmol/L. The triglyceride (TG) level was 1.27 (0.97, 1.80) mmol/L, the low-density lipoprotein cholesterol (LDL-C) level was 2.34 (1.88, 2.88) mmol/L and the high-density lipoprotein cholesterol (HDL-C) level was 1.31 (1.08, 1.59) mmol/L. Except for the TC level in women aged 65-75 years and LDL-C levels in women aged 55-64 and 65-75 years, there were significant differences in TC, TG, LDL-C and HDL-C levels between subjects of control group, hypertension group, diabetes group, and hypertension-diabetes group in different age ranges (including 35-44, 45-54, 55-64,and 65-75 years) and genders(all P<0.01).Except for the LDL-C and HDL-C in men aged 35-44 years and LDL-C in women aged 65-75 years, there were significant differences in the dyslipidemia rates of TC, TG, LDL-C and HDL-C between subjects of control group, hypertension group, diabetes group and hypertension-diabetes group in different age ranges and genders(P<0.01 or <0.05). After adjusting for age, gender, smoking, drinking, snoring, region, and body mass index, multivariate logistic regression analysis showed that hypertension (OR=1.221, 95%CI 1.113-1.339, P<0.01), diabetes (OR=1.636, 95%CI 1.461-1.833, P<0.01) and hypertension-diabetes (OR=1.832, 95%CI 1.658-2.023, P<0.01) were independent risk factors for TC abnormality. Hypertension (OR=1.566, 95%CI 1.478-1.659, P<0.01), diabetes (OR=2.182, 95%CI 2.031-2.342, P<0.01) and hypertension-diabetes (OR=2.655, 95%CI 2.492-2.829, P<0.01) were also independent risk factors for TG abnormality. Diabetes (OR=1.510, 95%CI 1.309-1.742, P<0.01) and hypertension-diabetes (OR=1.461, 95%CI 1.285-1.661, P<0.01) were independent risk factors for LDL-C abnormality. Diabetes (OR=1.261, 95%CI 1.180-1.346, P<0.01) and hypertension-diabetes (OR=1.195, 95%CI 1.126-1.268, P<0.01) were independent risk factors for HDL-C abnormality. Conclusion The prevalence of dyslipidemia in patients with hypertension and diabetes is high in Henan province, so adequate blood lipid education and control should be applied to people with risk factors as soon as possible.

Objective To investigate the prevalence of Spirometra mansoni infections in hosts in Jiangsu Province, so as to provide the scientific basis for the management of sparganosis mansoni. Methods From 2018 to 2019, nine counties (cities, districts) were randomly selected from Jiangsu Province as the survey sites, and 100 healthy individuals were randomly selected to perform the serological test of S. mansoni infections and the detection of S. mansoni eggs. The procercoids were detected in the intermediate host Cyclops, and the S. mansoni eggs were identified in the stool samples of the definitive hosts cats and dogs. Results The prevalence of S. mansoni human infections was 0 (0/900) in the 9 survey sites of Jiangsu Province, and the sero-prevalence of the specific IgG antibody against S. mansoni was 1.22% (11/900). The positive rate of procercoids was 0.33% (3/900) in Cyclops. In addition, the S. mansoni egg-positive rate was 1.48% (2/135) in cats and dogs. Conclusions Sparganosis mansoni is prevalent in Jiangsu Province. Health education pertaining to the damages of sparganosis mansoni and the route of S. mansoni infections should be improved.
