Objective To investigate the distribution and drug resistance of carbapenem-resistant Enterobacteriaceae ( CRE) isolated from children in China. Methods CRE strains were collected in 10 ter-tiary children's hospitals of China from January 1, 2016 to December 31, 2017. Antimicrobial susceptibility of the clinical strains was detected with disk diffusion method ( KB method) and automated method. The re-sults were analyzed according to the Clinical and Laboratory Standards Institute ( CLSI) Standards published in 2017. WHONET 5. 6 software was used to retrospectively analyze the distribution characteristics and drug resistance of these strains. Results A total of 3065 CRE clinical strains were isolated from children with an overall prevalence of 7. 7％ and among them, 13. 5％ were isolated in neonatal group and 5. 8％ in non-neo-natal group. The detection rate of CRE in 2017 was higher than that in 2016 (9. 7％ vs 5. 7％). Among the 3065 CRE strains, there were 1912 strains of Klebsiella pneumoniae (62. 0％), 667 strains of Escherichia coli (22. 0％), 206 strains of Enterobacter cloacae (7. 0％), 56 strains of Klebsiella aerogenes (1. 8％) and 47 strains of Serratia marcescens (1. 5％). Most of the strains were isolate in neonatology departments including neonatal intensive care units (NICU) and intensive care units (ICU), accounting for 44. 8％ and 19. 7％, respectively. Respiratory tract (61. 8％), urine (19. 4％) and blood (5. 7％) specimens were the main sources of CRE isolates. Results of antimicrobial susceptibility test showed that the CRE strains were highly resistant to carbapenem antibiotics such as imipenem, meropenem and ertapenem, as well as penicillins and most cephalosporins (79. 6％-100％), especially those isolated in the neonatal group (P<0. 05). Children had relatively low resistance rates to aminoglycosides such as amikacin (19. 7％) and fos-fomycin (11. 9％), fluoroquinolones such as levofloxacin (37. 7％) and ciprofloxacin (43. 3％), and tige-cycline (3. 8％). Currently, no polymyxin B-resistant strains were isolated. Conclusions The prevalence of common CRE strains in children in 2017 was higher than that in 2016, especially in newborns. Drug re-sistance in CRE strains isolated from neonates to common antibiotics was more severe, suggesting that great attention should be paid to it and timely measures should also be taken.

AIM: To study the chemical constituents and bioactivity of the stem bark of Mitragyna diversifolia. METHOD: Compounds were isolated by various chromatographic methods. Their structures were elucidated on the basis of spectroscopic techniques (IR, UV, MS, and NMR), and they were evaluated for their cytotoxic activities by the MTT method. RESULTS: Eight triterpenes were isolated and identified as 3α, 6β, 19α-trihydroxy-urs-12-en-28-oic acid (1), 3β, 6β, 19α-trihydroxy-urs-12-en-28-oic acid (2), 3-oxo-6β-19α-dihydroxy-urs-12-en-28-oic acid (3), 3β, 6β, 19α-trihydroxy-urs-12-en-24, 28-dioic acid 24-methyl ester (4), 3β, 6β, 19α, 24-tetrahydroxy-urs-12-en-28-oic acid (5), rotundic acid (6), 23-nor-24-exomethylene- 3β, 6β, 19α-trihydroxy-urs-12-en-28-oic acid (7), and pololic acid (8), respectively. All of the isolates were tested against two human tumor cell lines, MCF-7 (breast) and HT-29 (colon). CONCLUSION Compound 1 was a new triterpene. Compounds 5 - 7 exhibited potent inhibitory effects on the growth of MCF-7 and HT-29 cells, and the others showed no cytotoxicity.

BACKGROUNDElevated fibrinogen (Fg) level is a known risk factor for ischemic stroke. There are few clinical trials on oral fibrinogen-depleting therapies for secondary ischemic stroke prevention. We aimed to assess the effects of one-year therapy with oral lumbrokinase enteric-coated capsules on secondary ischemic stroke prevention.

METHODSThis is a multicenter, randomized, parallel group and controlled study that began treatment in hospitalized patients with ischemic stroke and continued for 12 months. Patients were randomized to either the control group that received the standard stroke treatment or the fibrinogen-depleting group that received the standard stroke treatment plus enteric-coated lumbrokinase capsules. The NIH Stroke Scale scores (NIHSSs) and plasma Fg level were recorded. The carotid artery intima-media thickness (IMT) and status of plaques were examined through carotid ultrasound examination. Primary outcomes included all-cause mortality, any event of recurrent ischemic stroke/transient ischemic attack (TIA), hemorrhagic stroke, myocardial infarction and angina, and other noncerebral ischemia or hemorrhage. Kaplan-Meier survival analysis and the Long-rank test were used to compare total vascular end point incidence between the two groups. Comparison of median values between two groups was done by the Student t test, one-way analysis of variance (ANOVA), or non-parametric rank sum test.

RESULTSA total of 310 patients were enrolled, 192 patients in the treatment group and 118 patients in the control group. Compared to the control group, the treatment group showed favorable outcomes in the Fg level, carotid IMT, the detection rate of vulnerable plaques, the volume of carotid plaques, NIHSS scores, and incidence of total vascular (6.78% and 2.08%, respectively) and cerebral vascular events (5.93% and 1.04%, respectively) (P < 0.05). In the treatment group, the volume of carotid plaques was significantly related to the carotid IMT, the plaque diameter, width and number (P = 0.000, 0.000, 0.000, 0.022; F = 13.51, 2.52, 11.33, -3.29, but there was a weak correlation with the Fg level (P = 0.056). After 1-year therapy, the incidence of overall vascular end points was reduced by 4.7%.

CONCLUSIONLong-term oral fibrinogen-depleting therapy may be beneficial for secondary ischemic stroke prevention.

OBJECTIVETo compare the treatment results of three-dimensional conformal radiotherapy (3D-CRT) and conventional radiotherapy (2D) for patients with locally advanced non-small-cell lung cancer (NSCLC).

METHODSFive hundred and twenty seven patients with stage III NSCLC treated between Jan 2000 and Dec 2006 were included in this study. Among them, 253 cases were treated with 3D-CRT, and 274 with conventional radiotherapy. In the 3D group, 159 (62.8%) patients received chemoradiotherapy, 77 with total radiotherapy dose of > 60 Gy, 49 with 50 - 60 Gy. In the 2D group, 127 (46.4%) patients received chemoradiotherapy, 48 with total radiotherapy dose of > 60 Gy, 75 with 50 - 60 Gy.

RESULTSThe 1-, 3-, 5-year overall survival rates (OS) and median survival time for patients treated with 3D-CRT were 73.3%, 26.1%, 14.4% and 20.1 months, respectively, and that of patients treated with 2D radiotherapy were 61.0%, 13.8%, 8.0% and 15.6 months, respectively (P = 0.002). The 1-, 3-, 5-year cause-specific survival rates (CSS) were 79.0%, 33.3%, and 20.8% for the 3D group and 65.1%, 16.7%, 11.2%, respectively, for the 2D group (P = 0.000). The 1-, 3-, and 5-year locoregional control rates were 71.6%, 34.3% and 31.0% for patients treated with 3D radiotherapy and 57.3%, 22.1% and 19.2%, respectively, for patients treated with 2D treatment (P = 0.002). The results of multivariate analysis showed that 3D-CRT, KPS, clinical tumor response and pretreatment hemoglobin level were independently associated with increased OS and CSS. No statistically significant differences were found between the radiation complications in the two groups.

CONCLUSIONSThe results of our study demonstrate that 3D-conformal radiotherapy improves the survival rate in patients with stage III NSCLC compared with that of 2D radiation therapy.

OBJECTIVETo perform cost-effectiveness analysis of interventions in female sex workers in Dehong prefecture in China, with an aim of providing evidence for rational resource allocation in female sex worker interventions in the future.

METHODSThe data of expenses for female sex worker interventions in Dehong from 2005 - 2007 were obtained through questionnaire survey. Meanwhile, the data from baseline survey in 2004, from surveillance of female sex workers from 2005 through 2007 as well as from the special survey on sexual transmission in 2007 were collected. Intervention effectiveness was estimated by using SEX 2.0 Tool recommended by UNAIDS. The cost-effectiveness ratio is calculated as the total cost divided by the number of estimated non-HIV patients due to these interventions.

RESULTSThe total cost for female sex worker interventions is 916 400 RMB from 2005 through 2007, and a total of 3297 female sex workers were effectively intervened in these three years. Thus, the actual intervention cost for each female sex worker (unit cost) is 277.9 RMB. If all the intervention work is performed as required, the predicted unit cost for female sex worker intervention would be 500.5 RMB. During the period of 2005 through 2007, 69 female sex workers had been successfully prevented from HIV infection; therefore, the cost-effectiveness ratio is 13 282 RMB.

CONCLUSIONIntervention among female sex workers is highly cost-effective.

OBJECTIVETo investigate whether the WNK lysine deficient protein kinase 4 (WNK4) gene C1155547T polymorphism is associated with essential hypertension (EH) in Xinjiang Kazakhs and to assess the effect of the interaction between this polymorphism and environment factors on EH.

METHODSThe study covered 556 hypertension patients and 341 normotensive controls. The C1155547T was determined by Taqman probe real-time PCR method. Some biochemical index such as glucose, triglyceride and total cholesterol were also measured. All of these results were analyzed with Logistic regression analysis. Additive model was applied to assess the effect of interaction between the WNK4 gene C1155547T polymorphism and environment factors on hypertension.

RESULTSThe C1155547T polymorphism was consistent with Hardy-Weinberg equilibrium in both the case and control groups. There was significant difference in the genotype frequencies (P=0.003). The T allele frequency was significantly higher in the patient group (P=0.002). Logistic regression analysis revealed that the age, body mass index (BMI), total cholesterol as well as the CT+TT genotype frequency conferred increased risks for EH. Positive interaction between the C1155547T polymorphism and gender, BMI, glucose was observed. The ORs were 3.85 (95%CI:1.23-12.04), 5.91 (95%CI:1.99-17.57) and 8.77 (95%CI:1.04-73.93), respectively.

CONCLUSIONThe result suggested that the exon 7 C1155547T polymorphism in WNK4 gene might be associated with EH in Xinjiang Kazakhs, the T allele might be the risk factor of essential hypertension. There were interactive effects between the WNK4 gene C1155547T polymorphism and gender, BMI and glucose.
