3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

Objective The role of BMI1 gene in the development of gastrointestinal stromal tumor (GIST) has not yet been clarified. This study aimed to explore the expression of BMI1 gene in gastrointestinal stromal tumor,and analyze its relationship with clinical pathological features of GIST. Methods The clinical data of 68 GIST patients treated in The First People's Hospital of Nan-ning from August 2012 to October 2015 were analyzed retrospectively. The expression of BMI1 in normal gastrointestinal tissues and GIST tissues were detected with immunohistochemistry method,and analyzed the relationship between various clinicopathological pa-rameters of GIST and BMI1. The expression of BMI1 protein was detected by Western blot. Results The positive rate of BMI1 was much higher in GIST group than in non-GIST (76.47% vs 36.84%,P<0.05). The difference in the expression of BMI1 protein between the different risk groups was statistically significant (P<0.05). The positive expression rate was the highest in the high-risk group (93.75%),but had no statistically significant difference among different genders,age,locations,histological types and whether me-tastasis (P>0.05). Expression of proliferation genes such as PCNA,CyclinD1 mRNA in BMI1 positive group were higher than those in BMI1 negative group,the expression of Pro-apoptotic genes such as Caspase-7,Smac mRNA were lower than those in BMI1 negative group,the expression of anti-apoptosis genes such as Livin,p53,Bcl-2 mRNA were higher than those in BMI1 negative group (P<0.05). Conclusion The expression of BMI1 protein was increased in GIST tissue. It is correlated with the risk classification,and is an important factor affecting the prognosis of patients.

BACKGROUNDThe pathophysiology of type 2 diabetes is progressive pancreatic beta cell failure with consequential reduced insulin secretion. Glucotoxicity results in the reduction of beta cell mass in type 2 diabetes by inducing apoptosis. Autophagy is essential for the maintenance of normal islet architecture and plays a crucial role in maintaining the intracellular insulin content by accelerating the insulin degradation rate in beta cells. Recently more attention has been paid to the effect of autophagy in type 2 diabetes. The regulatory pathway of autophagy in controlling pancreatic beta cells is still not clear. The aim of our study was to evaluate whether liraglutide can inhibit apoptosis and modulate autophagy in vitro in insulinoma cells (INS-1 cells).

METHODSINS-1 cells were incubated for 24 hours in the presence or absence of high levels of glucose, liraglutide (a long-acting human glucagon-like peptide-1 analogue), or 3-methyadenine (3-MA). Cell viability was measured using the Cell Counting Kit-8 (CCK8) viability assay. Autophagy of INS-1 cells was tested by monodansylcadaverine (MDC) staining, an autophagy fluorescent compound used for the labeling of autophagic vacuoles, and by Western blotting of microtubule-associated protein I light chain 3 (LC3), a biochemical markers of autophagic initiation.

RESULTSThe viability of INS-1 cells was reduced after treatment with high levels of glucose. The viability of INS-1 cells was reduced and apoptosis was increased when autophagy was inhibited. The viability of INS-1 cells was significantly increased by adding liraglutide to supplement high glucose level medium compared with the cells treated with high glucose levels alone.

CONCLUSIONSApoptosis and autophagy were increased in rat INS-1 cells when treated with high level of glucose, and the viability of INS-1 cells was significantly reduced by inhibiting autophagy. Liraglutide protected INS-1 cells from high glucose level-induced apoptosis that is accompanied by a significant increase of autophagy, suggesting that liraglutide plays a role in beta cell apoptosis by targeting autophagy. Thus, autophagy may be a new target for the prevention or treatment of diabetes.

OBJECTIVETo evaluate the clinical efficacy of treatment on the cases of severe hallux valgus by the first metatarsal basal osteotomy combined with Chevron-Gerbert operation.

METHODSFrom June 2004 to August 2008, 37 cases of severe hallux valgus (66 feet) underwent first metatarsal basal osteotomy combined with Chevron-Gerbert operation. There were 5 males (10 feet) and 21 females (38 feet), aged 21 - 76 years (mean 58 years). For all patients with follow-up, radiographic measurements of frontal and lateral position of foot were taken to measure the hallux valgus angle (HVA), the IMA (intermetatarsal angle) and the proximal articular set angle (PASA) preoperatively, postoperatively and in follow-up respectively. The measuring results were compared among the preoperative, the 6-week postoperative and the final follow-up. At the same time the patients were evaluated with the AOFAS Maryland score.

RESULTSOf the original 37 patients, 26 patients (48 feet) were followed up. The mean durations of follow-up was 2.3 years (range from 1 to 4 years). At final follow-up, HVA corrected 25.6° ± 3.8°, IMA corrected 8.6° ± 2.4°, and PASA corrected 4.7° ± 4.2°. According to AOFAS rating system, 91.7% patients were rated as excellent or good with excellent in 15 patients (28 feet), good in 8 patients (16 feet), and fair in 3 patients (4 feet).

CONCLUSIONSFirst metatarsal basal osteotomy combined with Chevron-Gerbert operation has good efficacy to the patients with severe hallux valgus. However there are disadvantages such as complexity relatively for multi-stage osteotomy and internal fixation.

The primers and probes for the Real-time RT-PCR were designed based on the multiple sequence (swine and humans HEV strains) alignments of the ORF3 region of genotype 4 HEV. A rapid, sensitive and stable TaqMan Real-time RT-PCR assay was established, and its specificity and sensitivity were assessed, and comparison of the Real-time RT-PCR with conventional and nested RT-PCR was performed. The results found that the crossing points showed linearly proportional to the logarithm of the input copy number. The correlation coefficient (R2) and the slope value of the standard curves with plasmid DNA were 0.994 and -3.312, respectively. The efficiency (E) of the PCR was 100%. Coefficients of variation values of the different diluted plasmid DNA were low in the same or different repeated experimental group. In addition, the assay was able to correctly detect genotype 4 HEV RNA from swine fecal samples. The sensitivity of established assay was 100-fold higher than that of conventional RT-PCR and 10-fold higher than nested RT-PCR.

OBJECTIVEThe purpose of this study was to investigate the clinical characteristics of lymph node metastasis in the contralateral mediastinum and scalene in patients with potentially operable nonsmall cell lung cancer (NSCLC).

METHODSCervical mediastinoscopy was performed for 89 patients with clinical stage I-III A non-small cell lung cancer prior to thoracotomy. Of these, 12 underwent cervical medistinoscopy combined with right scalene lymph node biopsy and 10 with anterior para-mediastinal small incision.

RESULTSA total of 9 patients were found have N3 disease on mediastinosopy, with cancer-cell-positive lymph nodes in the contralateral mediastinum in 6 and 3 in the right scalene. Statistical analysis revealed that the incidence of N3 disease in adenocarcinoma group was higher than that in patients with nonadenocarcinoma (P < 0.05), which was also higher in the patients with serum CEA >5 ng/ml than that in the patients with CEA <5 ng/ml (P < 0.05), and it was higher in the patients with ipsilateral mediastinal multi-station lymph node metastasis than that in the patients with uni-station lymph node metastasis (P < 0.05).

CONCLUSIONBiopsy of contralateral mediastinal lymph nodes or scalene lymph node should be performed in order to exclude N3 disease for potentially operable NSCLC patients with adenocarcinoma, serum CEA >5 ng/ml or ipsilateral multi-station mediastinal lymph node metastasis.

OBJECTIVETo evaluate the effect of thoracic radiation therapy (TRT) on patients with extensive stage small-cell lung cancer (SCLC).

METHODSOne hundred and fifty-four patients with extensive stage SCLC treated in our department between January 2003 and December 2006 were enrolled in this study. Eighty nine patients received chemotherapy and thoracic radiation therapy (ChT/TRT), and 65 patients were treated with chemotherapy alone (ChT without TRT). The chemotherapy was CE (carboplatin and etoposide), PE (cisplatin and etoposide) or CAO (CTX, ADM and VCR) regimens. The total dose of thoracic irradiation was 40-60 Gy with 1.8 - 2.0 Gy per fraction.

RESULTSFor the whole group, the median survival time (MST) was 13.7 months, the 2-year and 5-year overall survival rates were 27.9% and 8.1%, respectively. The MST, overall survival rates at 2 years and 5 years in the ChT/TRT group and ChT without TRT group were 17.2 months, 36.0%, 10.1% and 9.3 months, 16.9%, 4.6%, respectively (P = 0.001). The median progression-free survival (PFS) for all patients was 8.0 months, the 2-year and 5-year PFS were 13.6% and 8.2%, respectively. The median PFS, 2-year and 5-year PFS in the ChT/TRT group and ChT without TRT group were 10.0 months, 17.4%, 10.5% and 6.2 months, 9.8%, 4.9%, respectively (P < 0.001). The incidence of intra-thoracic local failure was 29.6% in the ChT/TRT group and 70.0% in the ChT/without TRT group (P = 0.000).

CONCLUSIONSChemotherapy plus thoracic radiation therapy can improve the overall survival, progress free survival and reduce local regional failure rate in patients with extensive stage SCLC compared with that by chemotherapy alone.

OBJECTIVETo investigate the current smoking regulations and their impacts on the environmental tobacco smoke (ETS) levels inside restaurants and bars in Beijing.

METHODSTelephone survey was used to investigate the smoking regulations. TSI Sidepak AM510 was used to measure the level of fine particles less than 2.5 microns in diameter (PM2.5) in restaurants and bars. Analysis of variance and non-parametric rank tests were used to examine the association between indoor and outdoor PM2.5 levels and (1) smoking regulations; and (2) types of restaurants and bars.

RESULTSOf the 305 restaurants and bars surveyed, 27.9% had complete or partial smoking prohibiting rules. The average indoor PM2.5, level of the 92 restaurants and bars was 253.08 microg/m3 , 102.37% higher than the outdoor level. The average indoor and outdoor PM2.5 levels in the restaurants and bars with smoking ban regulations were 93.10 microg/m3 and 110.33 microg/m3 whole 289.34 microg/m3 and 128.40 microg/m3 in those without, respectively. The average indoor and outdoor PM2.5 levels of bars were 413.46 microg/m3 and 190.62 microg/m3, respectively, while in the western fast-food restaurants, they were 83.86 microg/m3 and 104.77 microg/m3, respectively. The outdoor PM2.5 levels were higher than the indoor levels in different classes of restaurants and bars. Furthermore, there was a significant positive correlation between PM2.5 levels and the number of smokers per cube meters (r = 0.47, P < 0.001).

CONCLUSIONSmoking regulations could effectively reduce the ETS level in restaurants and bars.

OBJECTIVETo investigate the human immunodeficiency virus (HIV) and syphilis incidence rates as well as the retention rate in a cohort with 6-month follow-up study among female sex workers (FSWs).

METHODSFrom December, 2004, to January, 2005, a community-based baseline survey was conducted to recruit 343 FSWs for a prospective cohort study in Xichang county of Sichuan province, China. Follow-up visits were conducted at 6 months to analyze risk factors associated with cohort retention for subjects' baseline sociodemographic and sexual behavioral characteristics. Blood specimens were also collected to test antibodies against HIV and syphilis.

RESULTSDuring the 6-month follow-up period, HIV and syphilis incidence appeared to be 1.00 per 100 person-years and 6.23 per 100 person-years, respectively. The rate of retention in the cohort was 53.6% (184/343). Results from multivariate logistic regression model showed that factors were significantly associated with cohort retention including people with minority ethnic background (OR = 0.36; 95% CI: 0.18-0.74), people having participated in AIDS prevention program (OR = 1.83; 95% CI: 1.17-2.86) or being clients in the last 6 months > or = 50 (OR = 1.75; 95% CI: 1.11-2.77) and having changed living/working place (OR = 0.56; 95% CI: 0.33-0.94).

CONCLUSIONThe results of this study showed that the syphilis incidence and unprotected sex behavior were high among local FSWs. People belonged to Han nationality, having participated in AIDS prevention program and having a steady living/working place were associated with cohort retention at 6-month follow-up study among FSWs, respectively.
