Objective To understand the prevalence and disease distribution of migrants within the water source area of the Middle Route Project of South-to-North Water Diversion Project and analyze the influencing factors. Methods By multi-stage stratified cluster sampling method, 307 immigrants and 676 immigrants were selected from Danjiangkou reservoir area, Shiyan city, Hubei Province. Results The prevalence of chronic diseases among in-migration was 51.8%. The prevalence rates of the top five chronic diseases were waist and leg pain, hypertension, gastritis, heart disease and diabetes. The prevalence of chronic diseases among out-migration was 65.1%. The prevalence rates of the top five chronic diseases were waist and leg pain, hypertension, gastritis, heart disease and bronchitis. The rate of chronic disease, the rate of two weeks and the rate of two weeks' visit were higher than that of emigration(all P<0.05). The results of multivariate analysis showed that the factors influencing the chronic diseases of immigrants were 60 years old (OR=59.928，P<0.001), unsatisfied family income (OR=0.377, P=0.002) and poor economic status (OR=0.517, P=0.028). The factors influencing the chronic diseases of immigrants were 60 years old (OR=26.190, P<0.001), smoking (OR=1.856,P=0.004), unsatisfactory family income (OR=0.598,P=0.029) and poor economic status (OR=0.460,P<0.001). Conclusions The prevalence of migrants within a high level is at a high level. Actually raising the income of immigrants is conducive to improving the health condition of immigrants.

OBJECTIVETo investigate the mechanism of how curcumin improves pulmonary vascular remodeling associated with chronic pulmonary arterial hypertension.

METHODSThe model of chromic hypoxia hypercapniapulmoary remodeling was made. Twenty-four male rats were randomly divided into 4 groups (n = 6): group I (normoxia control group), group II (hypxia and hypercapnia model group), group II (disodium cromoglycate control group), group IV (curcumin treated group). The last 3 group rats were put in a hypoxia cabin where the concentrate of O2 was 8% - 11% and the concentrate of CO2 was 3% - 5%, for 8 h a day and lasting 4 w in total. Group III rats were intraperitoneally injected with disodium cromoglycate (20 mg/kg) and group IV rats were administrated with curcumin by gavage (150 mg/kg). The morphological changes of pulmonary vessel walls and the ultrastructure of mast cells were observed by the optics microscope and the transmission electron microscope. Mast cells and its degranulation state were measured by toluidine blue staining and immunohistochemistry. Data were expressed as means ± SD (standard deviation) and analyzed with SPSS17.0 software.

RESULTS(1) By optics microscopy observation, the value of WA/TA was significantly higher in II group than other groups (P < 0.05). (2) Electron microscope showed that the endothelial cells of pulmonary arterioles in III and IV group were near to I group and the proliferation of pulmonary arterial media smooth cell layer and collagen fibers in adventitia was much lighter than those in II group. The membrane of mast cells was more intact in I, III, IV group than II group. (3) The number of mast cells, the degranulation rate of master cells and the number of positive tryptase stained cells in II group were significantly more than those in other groups. (P < 0.05).

CONCLUSIONCurcumin may inhibit the remodeling of pulmonary vessel induced by chronic hypoxia hypercapnia by mast cell regulation.

OBJECTIVETo investigate the effect of infrasound therapy on the proliferation, apoptosis and ultrastructure of human B lymphoma Raji cells.

METHODSHuman B lymphoma Raji cells were exposed to infrasound treatment for 15, 30, 60, 90 and 120 min and cultured subsequently for 24 or 48 h. MTT assay, flow cytometry analysis, and electron microscopy were performed to examine the proliferative status, cell apoptosis and ultrastructural changes of the exposed cells, respectively.

RESULTSMTT assay revealed no significant changes in the proliferation of the cells exposed to infrasound treatment (P>0.05), nor did flow cytometry analysis identified significant variation in the cell apoptosis (P>0.05). Scanning electron microscopy, however, identified shortened or reduced cell processes and microvilli on the surface of the cells with infrasound exposure and a subsequent 24-hour culture, and the cell membrane surface became smooth. Under transmission electron microscope, the cells with infrasound treatment presented with significantly reduced microvilli, and the cell nuclei appeared homogeneous, with cytoplasmic budding and losses after a 48-hour culture.

CONCLUSIONInfrasound less than 90 dB does not obviously affect the proliferation and apoptosis of Raji cells, but may directly cause cell ultrastructural changes such as reduction of the cell processes.

OBJECTIVETo study the association of alanine aminotransferase (ALT) with overweight or obesity in children.

METHODSA total of 2889 healthy children and 702 overweight or obese children aged from 7 to 18 years who had received a physical examination were enrolled. Height, body weight, waist circumference, and blood pressure were measured, and the biochemical indicators including blood glucose, blood lipids, ALT, and insulin were detected. The insulin resistance index were calculated.

RESULTSThe ALT level was significantly higher in boys than in girls. Along with the increase of BMI, the ALT level increased in the normal, overweight, and obese groups in both boys and girls. ALT was correlated with BMI, waist circumference, triglyceride, and insulin resistance index. Among the overweight or obese children, the boys with the increased ALT level had higher BMI, waist circumference, blood pressure, triglyceride, low density lipoprotein and insulin resistance index than the boys with normal ALT level (P<0.05); the girls with the increased ALT level had higher waist circumference, blood pressure and insulin resistance index and lower high density lipoprotein than the girls with normal ALT level (P<0.05).

CONCLUSIONSALT is correlated with overweight and obesity and metabolic disorders caused by overweight and obesity such as dyslipidemia and insulin resistance.

Objective To evaluate the advantages of sevoflurane inhalation anesthesia combined with lumbosacral plexus block for hip replacement in elderly patients. Methods Sixty patients of both se-xes, aged 65-85 yr, with body mass index of 18-25 kg∕m2, of American Society of Anesthesiologists physical statusⅠ-Ⅲ, scheduled for elective unilateral hip replacement, were divided into 2 groups(n=30 each)using a random number table: total intravenous anesthesia group(TIVA group)and GasMan software-guided sevoflurane inhalation anesthesia combined with lumbosacral plexus block group(SEV-B group). After the laryngeal mask airway was inserted, the patients were mechanically ventilated in both groups. Heart rate and mean arterial pressure(MAP)were recorded before anesthesia(T0), immediate-ly after insertion of laryngeal mask airway(T1), immediately after skin incision(T2), immediately after intramedullary reaming(T3), immediately after prosthesis implanting(T4), at the end of surgery(T5) and at 5 min after removal of the laryngeal mask airway(T6). The end-tidal concentration of sevoflurane at T2-5was also recorded in group SEV-B. The time for removal of the laryngeal mask airway, duration of stay in post-anesthesia care unit and first ambulation time were recorded. The consumption of anesthetics used during patient-controlled intravenous analgesia(PCIA), effective pressing times of PCIA, requirement for rescue analgesic and adverse reactions were also recorded at 24 h after surgery. The patient′s cognitive func-tion was assessed using Mini-Mental State Examination at 1 day before surgery and 1 and 3 days after surger-y, and the occurrence of postoperative cognitive dysfunction was recorded. Results Compared with group TIVA, heart rate at T1-6and MAP at T2-6were significantly decreased, and MAP at T1was increased in group SEV-B, and the time for removal of the laryngeal mask airway, duration of stay in post-anesthesia care unit and first ambulation time were significantly shortened, the consumption of anesthetics used during PCIA, effective pressing times of PCIA, requirement for rescue analgesic and incidence of adverse reac-tions were reduced at 24 h after surgery, the Mini-Mental State Examination scores were increased at 1 day after surgery, and the incidence of postoperative cognitive dysfunction was decreased at 1 day after surgery in group SEV-B(P<005). Conclusion GasMan software-guided sevoflurane inhalation anesthesia com-bined with lumbosacral plexus block can provide more accurate anesthesia management for hip replacement and promote rapid rehabilitation after surgery in elderly patients.

Objective To investigate the association between obesity and prevalence of metabolic syndrome (MS) with its associated risk factors,in children and adolescents.Methods A stratified random sampling method was used to select 7893 students from 6 to 18 years of age from 14 out of 396 primary and secondary schools in Nanning city.All the students had undergone physical examination and blood tests including the following risk factors related to metabolic syndrome:fasting blood glucose (FBG),total cholesterol (TC),triglycerides (TG),high-density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),alanine amino shift enzyme (ALT),aspartic acid amine shift enzyme (AST) and fasting insulin (FINS).The homeostasis model assessment insulin resistance index (HOMA-IR) was also measured.Results (1) The prevalence rate of MS in normal group was 0.57％.In both the overweight and obesity groups,the prevalence rates of MS were 4.53％ and 26.80％,respectively.(2) These indices in obesity group were higher than other two groups (P＜0.05).The result of overweight group was higher than normal group (P＜0.05).(3) Waist circumference(OR=1.087,95％CI:1.033-1.143 ),SBP ( OR=1.073,95％CI:1.032-1.116),FBG (OR=1.394,95％CI:1.568-3.423),TG (OR=3.213,95％CI:1.410-7.319) and HDL-C (OR=0.001,95％CI:0.000-0.012)were detecting indices which had statistically significant with MS in binary logistic regression analysis.Conclusion Metabolic syndrome and obesity were closely related in children and adolescents while its prevalence and risk factors increased with the severity of obesity.

Objective:To evaluate the efficacy and toxicity of single-agent bendamustine in patients with indolent B-cell non-Hodgkin's lymphoma (NHL) refractory to rituximab. Methods:Between April 2010 and April 2013, 100 patients with rituximab-refrac-tory indolent B-cell NHL from 8 institutions were enrolled. Bendamustine was administered at 120 mg/m2 on days 1 and 2 every 21 days for 6-8 cycles. The primary endpoint was the overall response rate (ORR). The secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results:One hundred patients with a median age of 56 (rang-ing from 28 to 74) years were recruited in this clinical study. The total number of chemotherapy was 447 cycles, and the median number was 4 cycles. Ninety-three patients could be evaluated for efficacy. Fifteen patients (16.1%) had complete remission (CR), 52 (55.9%) had partial remission (PR), 22 (23.7%) had stable disease (SD), and 4 (4.3%) had progression disease (PD). The ORR and DCR were 72%and 95.7%, respectively. After a median follow-up of 26.6 months (ranging from 2 to 48.4 months), 59 patients (63.4%) had PD.The median PFS was 8.53 (95%CI:6.518-10.542) months, and PFS rate for 1 year was (40.6±5.3)%. Forty-eight patients (48%) had 3/4 grade adverse events, including leucopenia (26%), neutropenia (24%), and anemia (11%). Conclusion:Single-agent bendamustine produced a high rate of objective responses in patients with rituximab-refractory indolent B-cell NHL and could be one of the new op-tions for second-line treatment of these patients. The most common adverse event is hematologic toxicity.
