Objective To explore the curative effects,prognostic factors,and adverse reactions of different treatment modalities of chemotherapy in patients with non-small cell lung cancer (NSCLC).Methods151 NSCLC patients were randomly assigned into 3 groups to undergo concurrent chemoradiotherapy ( n = 43 ) ,sequential chemo-radiotherapy ( n = 49 ) ,or pure chemotherapy (n = 59).The clinical data were analyzed.ResultsThe short-term effective rates of the concurrent and sequential chemo-radiotherapy groups were 81.4% and 73.5% respectively with no significantly difference between them,but both significantly higher than that of the pure chemotherapy group ( 39.0% ,both P ＜ 0.05 ).The mortality of the concurrent cherno-radiation group was 53.5% ,significantly lower than those of the sequential chemo-radiotherapy and pure chemotherapy groups (67.3% and 67.8% respectively,both P ＜0.05).The median survival time of the concurrent chemo-radiotherapy group was 26 months,significantly longer than those of the sequential chemo-radiotherapy and pure chemotherapy groups ( 12 and 11 months respectively,both P ＜ 0.05).The l-year survival rates of the 3 groups were 80.2% ,47.1%,and 45.6%.The 2-year survival rates were 58.2% ,38.5% ,and 24.4% ,and the 3-year survival rates were 32.7% ,27.5% ,and 0,respectively.The white blood cell decrease rates of the grades Ⅲ～Ⅳ of the concurrent chemo-radiotherapy group were significantly higher than those of the other 2 groups (both P ＜0.05 ).There were no significant differences in the rates of radiation esophagitis and radiation pneumonitis between the concurrent and sequential chemo-radiotherapy groups.Age,performance status score,clinical staging,and treatment modality were the 4 influencing factors in the prognosis of NSCLC ( all P ＜ 0.05 ).Conclusion Relatively safe with tolerable adverse reactions,concurrent chemo-radiotherapy is superior to sequential chemo-radiotherapy,particularly to pure chemotherapy,in increase of median survival time and survival rate in treatment of NSCLC.Age,PS,clinical staging and therapy method are independent indicators influencing the prognosis.

[Summary] Glucose homeostasis is precisely regulated by glucagon of pancreaticαcell and insulin ofβcell secretion.Diabetes is a chronic disease characterized by insulin deficiency or insulin resistance (IR). Absolute or relative excess of glucagon secretion may play an important role in the development of diabetes.Previously more studies on the functions of islet βcells were reported,but less on islet αcells. There are a variety of factors involved in the regulation of glucagon secretion,such as nutrients,endocrine hormones and neurotransmitters. High fasting and postprandial blood glucose in patients with diabetes are associated with increased glucagon.Isletαcell dysfunction is closely related to the development of diabetes and the ability of responding to hypoglycemia.Further studies of α cell function and its role on the development of diabetes could provide insight into the treatment of diabetes.

Objective To evaluate the long-term prognostic capacity of the SYNTAX score Ⅱ(SxScore Ⅱ) and SYNTAX score (SxScore) in patients undergoing left main percutaneous coronary intervention (LM-PCI). Methods A total of 209 patients undergoing unprotected LM-PCI in the Cardiology Department of the Affiliated Hospital of PAP of Logistic College were prospectively collected. Follow up was carried out by telephone or outpatient or rehospitalization. The clinical endpoint focused on MACCE after PCI including composite death, nonfatal myocardial infarction, target vessel revascularization and stroke. The secondary endpoint included cardiac death and stent thrombosis. The SxScore and SxScoreⅡ were retrospectively calculated according to results of coronary angiography and clinical features of patients. Patients were stratified according to tertiles of low (≤22), intermediate (23-32), and high (≥33). The clinical data were comparedbetween three groups. The predictive ability of two scoring systems to MACCE after PCI was compared by COX regression evaluation. Results In 209 patients, 12 patients were lost to follow-up (5.7%), and the median follow-up was 30.2 months, 56 cases (28.4%) were observed to suffer from MACCE. The incidence rates of MACCE were 19.0%, 28.6%and 44.4%in SxScore low, intermediate and high groups respectively. The incidence rates of MACCE were 12.8%, 23.8%and 45.5%in SxScoreⅡlow, intermediate and high groups respectively. Single factor analysis showed that SxScore, SxScoreⅡ, age, diabetes and left ventricular ejection fraction (LVEF) were the independent predictors of MACCE. Multivariate analysis showed that SxScore and SxScoreⅡwere still risk independent predictors for MACCE. Conclusion Both SxScore and SxScoreⅡare independent risk predictors for MACCE in patients with unprotected left main coronary artery disease undergoing PCI treatment.

OBJECTIVE To investigate existed or potential dangerous incidents in the daily work of sterilization and supply center, and establish countermeasures against them. METHODS The causes of dangerous incidents confirmed by nursing department from Jun 2006 to Oct 2007 were analyzed. RESULTS The most common dangerous incidents were nonstandard clinical self-prepared operation packs, non-fully cleared appliance and the non-turnoff of storage aperture. And the rate of the incidents was 18.6%, 10.9% and 9.2%, respectively. Direct dangerous incidents accounted for 72.3% and indirect dangerous incidents accounted for 27.7% in the total number of dangerous incidents. CONCLUSIONS The dangerous incidents can be reduced effectively by adopting relevant measures, enhancing risk surveillences and supervising the high-risk parts.

Objective To establish the method for content determination of total coumarins in Fructus Cnidii.Methods The content of the total coumarins was determined by UV spectrophotometry.Results The optimal detective wavelength was 320 nm for the total coumarins.Satisfactroy linear relationship with the absorbability was achieved when the mass concentration of osthole was within the range of 2～12 ?g/mL(r=0.999 5).The average recovery rate was 99.39%(RSD=2.67%,n=6).Conclusion The method is simple,accurate and sensitive,and it can be used for the quality control of Fructus cnidii and its preparation.

OBJECTIVE:To explore the distribution and drug resistance of pathogens in patients with hospital-acquired pneumo-nia(HAP)from neurosurgery department of the First Affiliated Hospital of Xinjiang Medical University(called“our hospital”for short),so as to provide reference for clinical use of antibiotics in the clinic. METHODS:The pathogen culture and drug sensitivity test of 652 HAP patients were analyzed retrospectively in neurosurgery department of our hospital during May 2011 to May 2015. RESULTS:Of 652 cases,pathogens were detected in 608 cases,with positive rate of 93.3%. Among 608 strains of pathogen, there were 443 strains of Gram-negative bacteria(71.2%)as Klebsiella pneumonia,Pseudomonas aeruginosa and Escherichia co-li;108 strains of Gram-positive bacteria (17.8%) as Staphylococcus aureus and Streptococcus pneumoniae;67 strains of fungus (11.0%)as Candida albicans. There were 67 strains of ESBLs K. pneumonia,43 strains of ESBLs E. coli and 8 strains of methicil-lin-resistant coagulase negative Staphylococci. The drugs sensitive to Gram-negative bacteria included imipenem,piperacillin sodi-um and tazobactam sodium,cefepime,etc.;those sensitive to Gram-positive bacteria included vancomycin,etc. CONCLUSIONS:Main pathogen of HAP patients in neurosurgery department of our hospital are Gram-negative bacteria,and they were highly resis-tant to antibiotics;the highly sensitive drugs to HAP include imipenem and vancomycin,etc.;the antibiotics should be used ratio-nally according to etiological analysis.

Objective To evaluate efficacy and adverse reactions of gensenoside Rg 3 combined with synchronous docetaxel and radiation treatment in elderly patients with non-small cell lung cancer (NSCLC).Methods 62 elderly patients with NSCLC were randomly divided into 2 groups:treatment group (n=32) were treated with radiotherapy and intravenous infusion of docetaxel and oral gensenoside-Rg3 at the same time,control group (n =30) were treated with radiotherapy and intravenous infusion of docetaxel at the same time.Objective response rate (ORR),disease control rate (DCR),the long term survival and adverse reactions were observed and compared between the two groups.Results The objective response rate and the disease control rate in treatment and control groups were 90.6％ versus 83.3％ and 96.9％ versus 90.0％ respectively,and the differences were not statistically significant (both P＞0.05).Median overall survival (OS) time and 1-,2-and 3-year survival rates in treatment and control groups were 17 months versus 10 months,56.3％ versus 43.3％,49.6％ versus 25.0％,and 27.5％ versus 15.0％,respectively,and the differences were statistically significant (x2 =4.19,P 0.04).The common adverse reactions in the two groups were myelosuppression,gastrointestinal reaction,hair loss,fatigue,joint sore.No one discontinued the treatment due to serious adverse reactions.There was no significant difference in the incidence of adverse reactions between the two groups (P＞0.05).Conclusions The gensenoside-Rg3 combined with synchronous treatment with docetaxel and radiation for elderly patients with NSCLC can prolong the survival time,improve quality of life and the prognosis with no significant increase in adverse reactions.
