Small cell lung cancer (SCLC) is a highly malignant tumor, which is very sensitive to first-line chemotherapy, but easy to recurrence and metastasis early.So it always has poor prognosis.Second-line therapy for SCLC develops slowly.Topotecan is the only drug approved by US Food and Drug Administration as a second-line chemoradiotherapy.Numerous studies on molecular targeted therapy and immunotherapy are being carried out, but most of them have no or little benefit.Rovalpituzumab tesirine (Rova-T) targeted antibody-drug conjugate (ADC) which is published at the 2016 American Society of Clinical Oncology Annual Meeting shows a good anti-tumor activity, which seems to bring a new dawn of molecular targeted therapy.

Objective To observe the association between the polymorphism of PINK1 gene exon 4 T313M and Parkinson's disease ( PD) in Xinjiang Uygurs.Methods The genetic DNA was extracted from 175 Uygur patients with PD (PD group) and 163 Uygur healthy controls (control group).The PINK1 gene exon 4 T313M was amplified by PCR.The genotype and allele were determined by restriction enzymes enzyme technology, and then validated by sequencing analysis.Results The frequency of PINK1 gene T313M T/T genotype in PD group was 2.9%, which of C/C genotype was 97.1%;the frequency of PINK1 gene T313M T allele in PD group was 2.9%, which of C allele was 97.1%.The frequency of PINK1 gene T313M T/T genotype in control group was 1.2%, which of C/C genotype was 98.8%;the frequency of PINK1 gene T313M T allele in control group was 1.2%, which of C allele was 98.8%. The difference of the polymorphism of PINK1 gene T313M between the two groups had no statistical significance ( P>0.05).Conclusion The polymorphism of PINK1 gene exon 4 T313M has nothing to do with the genetic susceptibility of Xinjiang Uighur PD patients.

Objective To analyze the incidence and risk factors of pelvic insufficiency fractures (PIF) in patients with cervical cancer who received pelvic intensity-modulated radiotherapy.Methods This study a retrospective review of all patients was performed with cervical cancer who received pelvic intensity-modulated radiotherapy at our institution from November 2013 to December 2015,and the incidence and risk factors of insufficiency fractures were analyzed.Results Among the 104 patients,16 (with a total of 31 lesions) were diagnosed with pelvic insufficiency fracture.The occurrence rate of pelvic insufficiency was 15.4％.Ten patients (62.5％) had multiple fractures and five patients (31％) complained of pain.All patients' pain was relieved by rest or analgesic drugs.Insufficiency fractures were detected at a median of 6.5 months (range 1-16) from radiotherapy completion.The distribution of PIFs was followed:sacral had 16 cases (51.6％),sacroiliac joint had 7 cases (22.6％),iliac had 6 cases (19.4％),femoral head had 1 case (3.2％) and pubis had 1 case (3.2％).Univariate analysis and multiple analysis showed that postmenopausal status and low body weight (≤55 kg) were thought to be risk factors for PIF(P ＜ 0.05).Subgroup analysis also confirmed that postmenopausal status was a risk factor for PIF (P ＜ 0.05) in postoperative cervical cancer patients after pelvic intensity-modulated radiation therapy.Conclusions Cervical cancer patients with menopausal status and low body weight (≤55 kg) are at some risk for the development of PIF after pelvic intensity-modulated radiotherapy.

Objective To present study was to investigate the effects of insulin-like growth factor binding protein 7 (IGFBP7)on the proliferation of human hepatocellular carcinoma HepG2 cells.Methods Human hepatocellular carcinoma HepG2 cells was cultured,and plasmid pIRES2-ZsGreen1-IGFBP7 or empty plasmid was transfected into HepG2 cells and the cell transfection efficiency was examined by fluores-cence microscopy;MTT was performed to evaluate the effect of IGFBP7 on proliferation and apoptosis of HepG2 cells in 48 hours after transfection.Results IGFBP7 transfected group decreased cell proliferation noticeably.Conclusions Overexpression of IGFBP7 can down-regulte the proliferation of human hepatocel-lular carcinoma HepG2 cells.

Objective To discover T cell reactive peptides of mycobacterium tuberculosis antigen Rv2608 for treatment or adjuvant treatment for tuberculosis.Methods The T cell epitopes of Rv2608 were predicted by bioinformatics.The long-chain peptides were screened with strong affinity with HLA-A0201,HLA-A1101,and HLA-A2402.The physical and chemical characters of the peptides were predicted.The stable and hydrophilic peptides for chemical synthesis were selected.The T cell reactivity of the peptides in patients with active tuberculosis was detected by ELISPOT.The results were compared with the clinical diagnosis kits TSPOT.TB.Results Four peptides of Rv2608 were predicted and screened,and they could be active T cells of patients with active TB.Rv2608p3 was the most efficient to prime the T cell response.Conclusions Software prediction was consistent with the result of ELISPOT.Rv2608p3 might be the candidate for therapeutic vaccine for tuberculosis.

Objective To investigate Monilia infection and adverse pregnancy outcomes of pregnant women in labor.Methods Before informed consent,542 cases of pregnant women in labor were collected in Obstetrics Department of Maternity and Child Healthcare of Maoming City from January 2013 to April 2014,and all of these cases were examined by Monilia inspec-tion of vaginal secretions.All of these cases were 20 to 30 years old,without vaginal pathogenic infection symptoms,but in-cluded in a few of formulation of clinical features of vaginal Candida infection.With the two methods of 10% potassium hy-droxide solution wet sheet and Gram staining,if blastospore or pseudohypha of Candida mycoderma were found out in the two methods under microscope,this case was diagnosed as positive result,otherwise as negative result.Respectively choosing positive cases as observation group,and negative cases as control group,the indexes of premature rupture of membranes,per-ineum wound infection,neonatal thrush and neonatal diaper rash of the two groups were recorded.The statistical method:e-numeration data by chi-square test,measurement data using analysis of varianc.Results The positive rate of Monilia was 23.1% (125/542),higher than 19.3% reported in domestic.The incidence rates of neonatal diaper rash,premature rupture of membranes,neonatal thrush and perineum wound infection of the observation group were respectively 19.2%,8.0%, 16.8% and 12.8%,all much higher than the control group respectively was 8.4%,1.2%,3.8% and 1.7%,(χ2 =12.578~29.273,all P <0.01).Conclusion Monilia infection of pregnant women in labor could increase the chance of adverse preg-nancy outcomes.Healthy or clinical doctors should suggest that pregnant women early carry out routine examination and ear-ly treatment,in order to prevent adverse pregnancy outcomes.

Objective To investigate the effects of different liver protective drugs on preventing liver injury induced by anti-tuberculosis drugs. Methods Retrospective analysis was made on 355 patients with primary pulmonary tuberculosis during intensified time. The patients received silibinon and bicyclol to prevent liver injury. 82 patients with TB were treated as control group during the same time. Results The number of patients with liver injury in silibinon group and bicyclol group were 16 cases (14.7%) and 55 cases (22.4%) respectively. The number of control group with liver injury was 9 cases (11.0%) (χ2 = 3.627,P > 0.05). The liver injuries within 4 weeks were mainly counted in. There is no difference between intervention and control groups(χ2 = 0.414,P > 0.05). There is no difference between three groups in liver injury degree (U = 0.288,P> 0.05). Conclusion Without high risk factors, anti-inflammatory and enzyme reduction drugs have no significant protective effects on liver injury caused by anti-tuberculosis drugs.

Objective To explore the value of endothelial dysfunction assessment in predicating major adverse cardiac and cerebrovascular events (MACCE) in peritoneal dialysis (PD) patients.Methods A prospective cohort study included 136 end stage renal disease (ESRD) patients from Jan 1,2009 to Dec 31,2011 was conducted.Endothelial function was assessed by flowmediated dilation (FMD) of brachial artery.Kaplan-Meier method was used to estimate survival rate.The survival difference between the two groups was compared by the log-rank test.Multivariate Cox proportional hazards regression was used to determine the independent risk factors of MACCE.Results In the follow-up period,18 patients in low FMD (FMD≤2.7％) group occurred MACCE,and 13 patients in high FMD (FMD ＞ 2.7％) group occurred MACCE.Compared with high FMD group,MACCE-free survival rate in the low FMD group had a significantly decreased (x2=4.190,P=0.041).Multivariate Cox proportional hazards regression analysis showed that higher level of total cholesterol,lower FMD,longer PD time and higher levels of hs-CRP were all independent predictors of MACCE.Conclusion Reduced brachial artery FMD is an independent risk factor of MACCE,and the application of FMD contributes to the risk stratification of cardiac and cerebrovascular disease in PD patients.

Objectives This study aimed at investigating the cellular mechanism of isoproterenol (ISO) on delayed afterdepolarizations (DADs) and triggered activity (TA) of the noninfarcted myocardium in the myocardial infarcted rabbit model.Methods Rabbits with the left anterior descending coronary artery occlusion were prepared and recovered for 8 wk (healed myocardial infarction, HMI). Myocytes were isolated from regions of the noninfarcted left ventricular free wall. ISO was added to cellular surface by perfusion way. Action potentials and ion currents were recorded with whole-cell patch clamp. Results The results showed that treatment with ISO induced more DADs and TA events in HMI myocytes. Iti and ICa-L of myocytes treated with ISO were increased significantly compared with HMI cells, which contributed to DADs-related triggered arrhythmia. Conclusions The results suggested that more arrhythmia events of DADs and TA developed in myocytes with ISO treatment. The underlying mechanism was associated with the augment of Iu and calcium influxing.
