Objective To know the quality of iodized salt and the current situation of the salt coverage in Tibet,and to provide scientific basis for proposing proper prevention and control measures to Iodine dificiency disorders(IDD). Methods In 2008, according to the "Sampling Methods of the Main Products in the Salt Industry",one batch fifteen salt samples were collected in iodized salt processing factory in Tibet. Five townships were chosen in each county based on 5 different directions of east, south, west, north and center. If the monitoring county has less than five townships, then all of the townships were sampled. In each township, four villages were selected withrandom sampling and importance sampling. In each township, 15 households were selected for salt collection. Results A batch of 15 salt samples in a salt processing plant were tested, and all of them were qualified with salt iodine(34.6±1.58) mg/kg. A total of 21 107 edible salt samples were tested, and 11 203 of them were qualified iodized salt. These results meant that the provincial iodized salt coverage rate was 53.08%. Shannan iodized salt coverage rate was 94.31% (3395/3600) which was the highest in Tibet. Those of Nagqu, Changdu, Ngari were lower, they were 29.84% (897/3006), 24.94% (823/3300) and 17.08% (205/1200), respectively. Conclusions The quality of iodized salt in Tibet is up to the national standard, but the coverage rate of iodized salt is very low.We suggest that the strategy should be carried out according to the national overall program strategy and supplement iodized oil capsule for special groups.

OBJECTIVETo investigate the effect of preoperative nutritional support in the management of patients with chronic radiation enteritis (CRE) with intestinal obstruction undergoing resectional surgery.
METHODSClinical data of 158 CRE patients undergoing diseased bowel resection from 2001 to 2011 were analyzed retrospectively. A total of 130 patients received preoperative nutritional support, including 28 patients with enteral nutrition support, 60 patients with total parenteral nutrition support, and 42 patients with combined nutritional support. The nutritional parameters, procedures, operation-related complications, and postoperative hospital stay were recorded.
RESULTSAfter aggressive nutritional support in 130 patients, patients nutritional index, such as serum prealbumin, transferrin, serum albumin improved significantly preoperatively, while the change of body mass index and hemoglobin was not significant. Compared to those without preoperative nutritional support, those who received preoperative nutritional support had lower stoma rate (31.5% vs. 53.6%, P=0.027), less postoperative infection rate (13.8% vs. 32.1%, P=0.019), shorter postoperative hospital stay [(14.1±7.3) d vs. (18.8±15.8) d, P=0.013). Enteral nutrition group had less postoperative infection rate (7.1% vs. 21.7%, P=0.017), lower stoma rate (28.6% vs. 48.3%, P=0.02), and shorter postoperative hospital stay [(15.5±9.6) d vs. (21.7±19.0) d, P=0.025) as compared to total parenteral nutrition group.
CONCLUSIONSPreoperative nutritional support can decrease the stoma rate, postoperative infection rate, and shorten hospital stay in CRE patients complicated with intestinal obstruction. If tolerated, enteral nutrition support should be chosen.

The inflammatory response is involved in the pathogenesis of the most common types of heart disease.Sanguinarine (SAN) has various pharmacological properties such as anti-inflammatory,antioxidant,antibacterial,antitumor,and immune-enhancing properties.However,few studies have investigated the effects of SAN on lipopolysaccharide (LPS)-induced inflammatory and apoptotic responses in H9c2 cardiomyocytes.Therefore,in this study,H9c2 cells were co-treated with SAN and LPS,and the mRNA levels of pro-inflammation markers and the apoptosis rate were measured to clarify the effect of SAN on cardiac inflammation.The underlying mechanism was further investigated by detecting the activation of Toll-like receptor (TLR)4/nuclear factor-κB (NF-κB) signaling pathways.As a result,increased mRNA expression of interleukin (IL)-1 β,IL-6,and TNFα induced by LPS was attenuated after SAN treatment;LPS-induced apoptosis of H9c2 cardiomyocytes and cleaved-caspase 8,9,3 were all significantly reduced by SAN.Further experiments showed that the beneficial effect of SAN on blocking the inflammation and apoptosis of H9c2 cardiomyocytes induced by LPS was associated with suppression of the TLR4/NF-κB signaling pathway.It was suggested that SAN suppressed the LPS-induced inflammation and apoptosis of H9c2 cardiomyocytes,which may be mediated by inhibition of the TLR4/NF-κB signaling pathway.Thus,SAN may be a feasible therapy to treat sepsis patients with cardiac dysfunction.

BACKGROUNDInoperable chronic thromboembolic pulmonary hypertension (CTEPH) is a severe clinical syndrome characterized by right cardiac failure and possibly subsequent liver dysfunction. However, whether serum markers of liver dysfunction can predict prognosis in inoperable CTEPH patients has not been determined. Our study aimed to evaluate the potential role of liver function markers (such as serum levels of transaminase, bilirubin, and gamma-glutamyl transpeptidase [GGT]) combined with 6-min walk test in the prediction of prognosis in patients with inoperable CTEPH.
METHODSFrom June 2005 to May 2013, 77 consecutive patients with inoperable CTEPH without confounding co-morbidities were recruited for this prospective cohort study. Baseline clinical characteristics and 6-min walk distance (6MWD) results were collected. Serum biomarkers of liver function, including levels of aspartate aminotransferase, alanine aminotransferase, GGT, uric acid, and serum bilirubin, were also determined at enrollment. All-cause mortality was recorded during the follow-up period.
RESULTSDuring the follow-up, 22 patients (29%) died. Cox regression analyses demonstrated that increased serum concentration of total bilirubin (hazard ratio [HR] = 7.755, P < 0.001), elevated N-terminal of the prohormone brain natriuretic peptide (HR = 1.001, P = 0.001), decreased 6MWD (HR = 0.990, P < 0.001), increased central venous pressure (HR = 1.074, P = 0.040), and higher pulmonary vascular resistance (HR = 1.001, P = 0.018) were associated with an increased risk of mortality. Serum concentrations of total bilirubin (HR = 4.755, P = 0.007) and 6MWD (HR = 0.994, P = 0.017) were independent prognostic predictors for CTEPH patients. Patients with hyperbilirubinemia (≥23.7 μmol/L) had markedly worse survival than those with normobilirubinemia.
CONCLUSIONElevated serum bilirubin and decreased 6MWD are potential predictors for poor prognosis in inoperable CTEPH.

OBJECTIVETo determine the magnetic resonance (MR) imaging findings of an ovarian mass which are most predictive of malignancy and assess the value of intravenous gadolinium administration in the characterization of an ovarian mass.
METHODSTotally 74 consecutive patients with a clinically or sonographically indeterminate adnexal mass underwent MR imaging, of whom 59 had subsequent surgical resection of 70 adnexal masses. These 59 patients formed the study population. MR imaging studies were prospectively and independently reviewed by a senior and a junior radiologist. The senior radiologist also reevaluated the studies in a blind fashion after a minimum 6 months interval. The sensitivity, specificity, positive predictive value, and negative predictive value of contrast-enhanced and unenhanced MR imaging were evaluated.
RESULTSThe most predictive MR imaging findings for malignancy were presence of vegetations in a cystic lesion and presence of necrosis in a solid lesion. The odds ratio was even higher when the ancillary finding of peritoneal metastasis or ascites was present. Contrast media contributed significantly to lesion characterization. Total 70 ovarian masses were detected by contrast-enhanced MR imaging including 37 malignant ovarian masses and 33 benign ovarian masses with 87% (61/70) accuracy, 86% (32/37) sensitivity, 88% (29/33) specificity, 89% (32/36) positive predictive value, and 85% (29/34) negative predictive value, whereas 70 ovarian masses were detected by unenhanced MR imaging with 74% (52/70) accuracy, 73% (27/37) sensitivity, 76% (25/33) specificity, 77% (27/35) positive predictive value, and 71% (25/35) negative predictive value. There were significant differences in accuracy (P < 0.01), sensitivity (P < 0.01), specificity (P < 0.01) between contrast-enhanced and unenhanced MR imaging.
CONCLUSIONContrast-enhanced MR imaging is highly accurate in detection and characterization of complex adnexal masses.

OBJECTIVETo investigate the association of ATP binding cassette transporter A1 (ABCA1) gene R219K polymorphisms with atrial fibrillation (AF) in Chinese population.
METHODSA total of 250 patients with AF and 250 control subjects were selected. Polymerase chain reaction-restricted fragments length polymorphism (PCR-RFLP) was used to determine the ABCA1 genotype, and the serum concentration of C-reactive protein (CRP) and high-density lipoprotein cholesterol (HDL-C) were measured in all the subjects.
RESULTSThe frequency of the RR , RK , KK , allele R , allele K genotype of ABCA1 in AF group and control group was 42.0%, 42.8%, 15.2%, 34.0%, 43.2% and 22.8%, 63.4%, 36.6%, 55.6%, 44.4%, respectively. The frequency of the KK genotype was significantly higher in the control group than in the case group (P=0.03), and the frequency of the allele K genotype was significantly different between the two groups (P=0.012). The serum CRP concentrations was significantly higher in AF group than in the control group (P=0.004), but serum HDL-C level showed no difference between the two groups. The serum CRP concentrations were significantly higher in patients with RR genotype than in those with KK genotype (P=0.013), and patients with RR genotype had significantly lower HDL-C level than those with RK and KK genotypes (P=0.009 and 0.027, respectively).
CONCLUSIONPatients with AF have elevated serum CRP level in comparison with healthy individuals, and the K allele of R219K polymorphism is an independent protective factor against AF.

OBJECTIVETo study the influence of distal tibiofibular synostosis on ankle function.
METHODSFrom October 1998 to October 2004, a total of 281 consecutive patients underwent operations because of ankle fractures or distal fractures of the tibia and fibula. Distal tibiofibular synostosis occurred after operation in 8 patients. The duration of follow-up averaged 20.6 months (14-44 months). The ankle function was assessed on the basis of functional rating system described by Mazur.(1)
RESULTSAccording to Mazur's ankle evaluation system, 4 patients achieved an excellent result, 2 a good result and 2 a fair result. The dorsiflexion of the synostosis ankle reduced by 8.26 degrees as compared with that of the contralateral ankle, and there was little influence on the plantar flexion. All the patients had a normal gait.
CONCLUSIONThe distal tibiofibular synostosis after the operation of ankle fractures or distal fractures of the tibia and fibula usually gives rise to few symptoms and needs no specific treatment.

OBJECTIVETo investigate the long term survival of MDR-TB patients compared to non-MDR-TB in Henan province in 2010.
METHODSParticipants were randomly selected in 2010 from a dataset generated by an anti-TB drug resistance surveillance survey conducted by the Tuberculosis Control Institute, Henan Centre for Disease Control and Prevention in 2001, supported by the World Health Organization. Information on patient's demographic profile and medical records was extracted by trained doctors and nurses at local anti-TB dispensaries. Interviews were carried out using questionnaires to collect information on the socioeconomic features and survival status. Bivariate and multivariate with logistic regression were performed for data analysis.
RESULTSThe long term outcome of MDR-TB patients was much poorer when compared to non-MDR-TB patients. The case fatality was much higher among MDR-TB than non-MDR-TB patients (22.1% vs. 6.7%). The risk factors associated with the poorer outcome would include drug resistance status, disease relapse, hospitalization for treatment and long treatment period. Compared to non-MDR-TB, the survival time for MDR-TB was much shorter after having had the disease (6.7 years vs. 8.0 years).
CONCLUSIONMDR-TB patients had poor long term outcomes. As most of the cured TB patients were under productive age in the society, the high case fatality rate of MDR-TB would impose big burden on the related family and communities. Findings from this study suggested that the TB control programs should involve more efforts be paid on MDR-TB control, in order to reduce the burden of the disease.
