Objective:To explore the expression of miR-139-5p in small cell lung cancer (SCLC)tissue and its clinical significance, and to clarify the role of miR-139-5p in the occurrence and development of SCLC. Methods:The biological function of miR-139-5p was examined by cell growth,apoptosis and cell cycle analysis. The expressions of miR-139-5p in 50 cases of cancer tissue and paracarcinoma normal tissue were examined by QRT-PCR.Combined with the clinical data,the role of miR-139-5p in clinic was anzlyzed.Results:The expression level of miR-139-5p in SCLC tumor tissue was lower than that in normal lung tissue (P <0.01).The expression level of miR-139-5p in the cells was un-regulated significantly after transferred miR-139-5p mimics (P <0.01).Compared with control group,the proliferation abilitiy of cells was reduced after up-regulating the expression of miR-139-5p (P < 0.01),the number of cells at G1 phase was increased (P < 0.05),and the cells were arrested at G0/G1 phase.The miR-139-5p expression was not associated with gender and age (P > 0.05).The expression level of miR-139-5p in the patient at LD stage was lower than that of the patients at ED stage (P <0.01).The expression level of miR-139-5p in the resistant patients was higher than that of the patients sensitive to chemotherappy (P <0.01).The expression level of miR-139-5p in the survival patients was lower than that in the death patients (P <0.01).Cox regression analysis indicated that miR-139-5p expression and disease stage were the independent prognostic factors for SCLC.Conclusion:miR-139-5p in participates in the occurrence and development of SCLC by inhibiting the cell proliferation,promoting apoptosis and inducing the cell cycle arrest;it may be used as a target gene to evaluate the prognosis of SCLC patients.

Objective To investigate the distribution and antibiotic resistance of pathogens isolated from inpatients with urinary tract infections.Methods A retrospective analysis was carried out on 1033 strains of pathogens isolated from urine culture in patients with urinary tract infections in Zhejiang Xiaoshan Hospital during January 2009 and December 2011.Urine specimens were cultured with Uricult,and K-B method was used for drug susceptibility test,WHONET 5.6 software was used to analyse drug susceptibility test.Results Among 1033 strains of pathogens,681 (65.9％) were gram-negative bacteria,197 (19.1％) were gram-positive bacteria,and 155 (15.0％) were fungi.The three most prevalent bacteria were Escherichia coli (402 strains,38.9％),Klebsiella pneumoniae (74 strains,7.2％) and Candida albicans (64 strains,6.2％).60.7％ (244/402) of Escherichia coli and 45.9％ (34/74) of Klebsiella pneumoniae were extended-spectrum β-lactamases (ESBLs) positive.Escherichia coli and Klebsiella pneumoniae were susceptible to imipenem,meropenem,cefoperazone/sulbactam,piperacillin/tazobactam and amikacin.Enterococcus and staphylococcus were susceptible to vancomycin,linezolid and furadantin.Candida was sensitive to flucytosine,voriconazole and amphotericin B.Conclusion Gram-negative bacteria mainly E.coli is the predominant pathogen to urinary tract infections in this group of patients.Regular analysis and monitoring of pathogen species and drug resistance is important for rational use of antibiotics.

Objective:To investigate the role of transforming growth factor β1 (TGF-β1) in multi-drug resistance in small cell lung cancer and its clinical significance.Methods:The mRNA and protein expressions of TGF-β 1 in H69 and H69AR cells were detected by real-time PCR and Western blot,respectively.After silence of TGF-[β1,the sensitivity of H69AR to drugs was detected by CCK8 assay.The expressions of TGF-β1 in lung cancer and paracarcinoma tissues were examined by QRT-PCR and immunohistochemistry.The relationship of TGF-β 1 expression with clinical pathological features and prognosis of patients was studied.Results:Compared to H69,the mRNA and protein expressions of TGF-β1 in H69AR cells were significantly increased by (5.93±0.47) and (8.49±1.92) folds,respectively (P＜0.01).Transfection ofTGF-β1 siRNA resulted in a decrease of TGF-β1 expression by 70.432％ in H69AR ceils (F=21.20,P＜0.01) and an increase insensitivity to chemotherapeutic agents of H69AR cells (t=4.576,P＜0.05).Compare with the paracarcinoma tissues,the expression of TGF-β1 was significantly increased in small cell lung cancer tissues (t=13.925,P＜0.01),which was closely related with clinical stage,chemosensitivity and overall survival (all P＜0.05),but not related with gender,age (both P＞0.05).Conclusion:TGF-β1 is involved in the regulation of small cell lung cancer multidrug resistance,which may be a potential marker to evaluate the chemosensitivity and dinical prognostic for small cell lung cancer.

Objective By discussing the state of lifestyle as well as affecting factors of kidney transplant recipients,to provide more health education content and basis for their physical and psychological health.Method With internationally accepted Health-Promoting Lifestyle Profile (HPLP),we surveyed the lifestyle of the selected 104 long-term follow-up cases of kidney transplant recipients.At the same time,163 sex-and age-matched healthy volunteers,who had no obvious abnormalities in the medical test,were chosen.Result For HPLP scores among the 104 cases of recipients,20 cases were excellent,67 cases good,17 cases common,and none was inferior.As a whole,its excellent rate was 83.65％.As for 129 healthy volunteers,their overall excellent rate was 70.55％.The HPLP scores for the nutrition behavior ranked top in kidney transplant recipients,followed by healthy responsibility behavior,and lowest for exercise behavior.For the healthy volunteers,the HPLP scores for interpersonal support behavior ranked top,followed by nutrition behavior,and lowest for healthy responsibility.Correlation analysis revealed that the HPLP scores in kidney transplant recipients were significantly and positively correlated with age (r =0.307,P =0.002) and educational level (r=0.370,P =0.000),and not with gender,ethnicity,occupation and kidney sources (P＞0.05).The HPLP scores in idney transplant recipients were higher than those in healthy volunteers,among which self-actualization and healthy responsibility showed statistically significant differences (P ＜ 0.05),there was no significant difference in exercise,nutrition,interpersonal support and stress management between recipients and healthy volunteers (P＞0.05).Conclusion The HPLP scores in kidney transplants was higher than in healthy volunteers,thereinto,stress management behavior and exercise behavior were relatively weak,which were the focused improvement projects of lifestyle of kidney transplant recipients.

Group-A rotaviruses are recognized as the most common cause of acute diarrhea. Phylogenetic analyses of the VP7 genes of rotaviruses circulating in Nanjing (China) could aid in the development of rotavirus vaccines. A total of 908 stool specimens were collected from patients suffering from acute diarrhea in Nanjing between October 2012 and December 2013, and were tested further for rotaviruses. Fifty rotavirus isolates selected randomly were typed by reverse transcription-polymerase chain reaction using serotype-specific primers for G genotyping. VP7 genes of 19 G9 strains were sequenced for further genetic characterization. Among the 908 stool specimens examined during the surveillance period, 103 (11.34%) were rotavirus-positive. G9 was the most predominant genotype (78.0%), followed by G2, G1 and G3. Sequence and phylogenetic analyses of the VP7 genes of serotype G9 rotaviruses revealed these strains to comprise two lineages (G9-VI, G9-III) and to be dominated by the G9-VI lineage (which belonged to a unique subcluster of Japanese and Chinese G9 strains). Amino-acid sequences of the four antigenic regions (A, B, C or F) were variant among a portion of strains, which may have contributed to the prevalence of G9 rotaviruses in this area.

Objective To establish an intestinal organoid-based assay to investigate the radiation mitigation effect of epiregulin in vitro. Methods Intestinal crypts were released from tissue incubated with EDTA. Intestinal crypts seeded in 3D matrigel were irradiated at 24 h after plating. The radiation mitigation effect of epiregulin was evaluated by measuring the survival rate, size and budding numbers of the organoid after irradiation, and the basic FGF was used as a positive control of epiregulin. Results Radiation-induced lethality and dose-dependent survival curve of the intestinal organoid were consistent with in vivo data. Treatment with epiregulin (400 ng/ml) at 24 h post-radiation significantly increased survival rate of 8 Gy X-ray irradiated intestinal organoid in comparison with non-treated group [(12.56 ± 1.02)％vs. (4.73 ± 0.38)％, t=12.43,P<0.05]. Conclusions Epiregulin has radiation mitigation effect on intestinal organoid and could serve as a potential medical countermeasure to mitigate gastrointestinal toxicity.

OBJECTIVETo survey the acceptance and willingness-to-pay for colorectal cancer colonoscopy screening among high risk populations in urban China.

METHODSFrom 2012 to 2013, a Cancer Screening Program in Urban China (CanSPUC) was initiated in 9 provinces, the current survey was conducted among those participants who were evaluated as "high risk for colorectal cancer" by a risk-factor-evaluation-model (community-based) and then went through a colonoscopy screening procedure (hospital-based). All the data were obtained through a questionnaire-based interview (face-to-face or self-completed), mainly focusing on the acceptance and willingness-to-pay of the participants for colorectal colonoscopy screening.

RESULTSThe current analysis included a total of 1 624 participants, with an median age of 55.0 years (P25 = 49.0, P75 = 61.0 years) and an annual income per capita of 17 thousand (range: 10-25 thousand) Chinese Yuan (CNY), 42.8% (695/1 624) of whom were males. Of all the participants, 87.0% (1 414/1 624) could totally or substantially accept the colonoscopy screening, particularly in those at higher education level (junior high school: OR = 0.34, 95% CI: 0.22-0.52; high school OR = 0.41, 95% CI: 0.26-0.66; college or over OR = 0.35, 95% CI: 0.20-0.59). Of all the participants, 13.0% (210/1 624) could not or hardly accept it, particularly in those with older age (60-69 years) (OR = 1.48, 95% CI: 1.06-2.07), not in marriage (OR = 2.15, 95% CI: 1.25-3.70) or with family member(s) to raise (OR = 1.60, 95% CI: 1.17-2.20). 1 388 (85.5%) of all the participants had willingness-to-pay for a long-term colonoscopy screening service, particularly in those working in public (OR = 0.61, 95% CI: 0.44-0.84) or enterprise sectors (OR = 0.60, 95% CI: 0.38-0.94), but 82.3% (1 141/1 386) of whom would only pay less than 100 CNY; 14.5% (236/1 624) of total had no willingness-to-pay, particularly in those living in areas with moderate (OR = 4.08, 95% CI: 2.75-6.33) or high GDP per capita (OR = 3.26, 95% CI: 2.11-4.92), or with an absence of willingness-to-pay for colonoscopy screening (OR = 3.98, 95% CI: 2.81-5.65).

CONCLUSIONSAlthough a larger community-based colorectal cancer screening program was warranted to examine the extrapolation of these findings, it suggested that the acceptance for colorectal cancer colonoscopy screening among the selected high-risk populations was considerable. The willing-to-pay was relatively high but the amount of payment was limited, the indicated subgroups with potentially less acceptance or willingness need to be more focused in the future to reach a higher participation rate. The data will also be informative in integrating the screening service into the local health insurance system.
