Objective To investigate the clinical manifestations and the antibiotics resistance patterns in children with positive blood culture of Escherichia coli. Methods The clinical data of children with positive blood culture of Escherichia coli were retrospectively analyzed from Jan.2007 to Dec.2014. Results In a total of 154774 children who had blood culture in the study period, 8446 children were positive, among whom 408 (4.83%) children were isolated Escherichia coli. The children with the positive blood culture of Escherichia coli mainly were under one year old (51.72%), of which 36.77%was neonates. There were 275 children had underlying diseases, and the most common disease was Leukemia. 199 (48.77%) Escherichia coli strains were producing extended spectrumβ-lactamase (ESBLs) and 85.23%were resistant to ampicillin. All strains were susceptible to meropenem. Conclusions Septicemia caused by Escherichia coli is usually occurred in children with leukemia or in neonates. Since blood infections of Escherichia coil had high rate of ESBLs, the use of carbapenem antibiotics should be cautious.

Objective: To reveal the therapeutic effect of acupuncture-moxibustion therapy for the treatment of post-stroke shoulder pain. Methods: Ninety patients with post-stroke acupuncture-moxibustion therapy (AM), acupuncture-moxibustion plus Chinese herbal decoction (AMCH), and Chinese herbal decoction (CH) respectively. Results: In the comparison of the therapeutic effects and blood viscosity, there was significant difference between the AM and CH group, as well as between the AMCH and CH group (P＜0.01); the difference was not significant between the AM and AMCH group. Conclusion:Acupuncture-moxibustion is an effective therapy in the treatment of the post-stroke shoulder pain, and it can also reduce the blood viscosity in short-term.

Objective To explore the effect of Chaihu Shugan Powder (CSP) on the content of 5-hydroxytryptamine (5-HT) in the hippocampus and the expression of tryptophan hydroxylase 2(TPH2) in median raphe nuclei in depression rats.Methods SD rats were randomly divided into normal group(n=12),model group (n=12),fluoxetine group (n=12),low-dose and high-dose CSP group (n =12,respectively).Depression model was made by reserpine intraperitoneal injection.During the experiment,the weight and the open-field scores were calculated;the content of 5-HT was detected by ELISA.The expression of TPH2 in median raphe nuclei was detected by Western blot.Results Compared with the weight ((225.02±5.23) g),the open-field scores ((12.6± 5.1)score) and content of 5-HT ((1.09±0.27) ng/ml) in the model group,high-dose CSP showed significantly improve the depressive rats in weight,open field score and content of 5-HT ((238.78±5.16) g,(15.6±7.8) score and (1.80±0.58) ng/ml,respectively;P＜0.05 or P＜0.01).The expression of TPH2 (0.66±0.21) in median raphe nuclei in the high-dose CSP group was apparently increased compared with that in the model group(0.16±0.04) (P ＜0.01).Conclusion CSP have the effects of anti-depression,which could be related with the increase of the 5-HT content in the hippocampus and the expression of TPH2 in median raphe nuclei.

Objective To identify the specific genotype and analyze clinical features of spinocerebellar ataxias (SCAs) pedigree in the region of Yunnan Province.Methods Fourteen SCAs pedigrees and 183 blood samples of the family members were collected between January 2011 and July 2014 from Department of Neurology,First Affiliated Hospital of Kunming Medical College.Polymerase chain reaction (PCR) amplification,agarose gel electrophoresis and DNA sequencing technologies were utilized to identify the specific genotype of SCAs pedigree.Presymptomatic tests were carried out and the clinical features and genetic test results of patients were carefully analyzed.Results SCA3 was the most common subtype of SCAs in the Han nationality of Yunnan region.Nine of the 14 families were SCA3,only one family was SCA2.Additionally,there were four SCAs families that remained indeterminate.The patients with di-allele mutations (46/77) of SCA3 gene had early onset,rapid progression and serious clinical symptoms.Hereditary SCA3 and autonomic dominant polycystic kidney disease can happen simultaneously in a family.The proband SCA3 gene' s CAG repeat number is 28/76,and repetitions of the mutation allele are in all range.The PKD1 gene exon 23 is found to be in abnormal sequence.Conclusions SCA3 is the most common subtype of SCAs in the Han population of Yunnan region.There are 15/46 incomplete penetrance nutation and 46/77 di-allele mutations.It is possible that di-allele mutations make the disease worse and accelerate clinical course progression.SCA3 and polycystic kidney disease can uncommonly happen simultaneously in a family,which perhaps suggests there are interactions between the two disease-virulence genes.

Objective To explore the clinical efficacy of nibble debridement combined with silver ions dressing in treatment of diabetic foot ulcer.Methods The data of 238 patients with diabetic foot ulcer in people's hospital of Meishan from January 2012 to December 2016 were retrospectively analyzed.Of which 125 patients were treated by nibble debridement combined with silver ions dressing(nibble debridement group),113 patients were treated with surgical debridement combined with silver ions dressing(surgical debridement group).The clinical efficacy,wound healing time and complication between two groups were compared.Results The wound healing time of nibble debridement group was (37.5 ± 10.8) days,which was shorter than (45.3 ± 11.7) days of surgical debridement group,the difference was significant (P ＜0.05).The total effective rate of nibble debridement group was 92.80％,which was higher than 73.45％ of surgical debridement group,the difference was significant(P ＜ 0.05).No complication occurred in two groups.Conclusion The method of nibble debridement combined with silver ions dressing treatment has a better satisfactory clinical result,shorter wound healing time and lower medical costs for patients with diabetic foot ulcer.

Objective To learn 2009~2014 Shaanxi Province sentinel surveillance six classes of HIV infection focus groups, and estimates of HIV-1 new infection.Methods Used enzyme-linked immunosorbent assay (ELISA)and Western blot (WB)experiments for the 2009~2014 HIV sentinel surveillance Shaanxi Province Category 6 focus groups conducted a total of 77 778 HIV antibody screening and confirmatory testing estimates of HIV-1 new infection.Results 2009~2014 men who had sex with men and people with HIV infection rate were 3.75%,8.77%,3.50%,5.00%,6.20% and 5.75%,and a slow upward trend;HIV-1 new infection were 5.04%,8.96%,5.01%,5.95%,4.68% and 6.39%,the overall downward trend. Young students,drug addicts,sex workers,pregnant women,and male STD clinic attenders five people with HIV infection and HIV-1 new infection were emerging to remain low.But male STD clinic attenders of HIV infection and HIV-1 new in-fection was emerging slowly rising trend.Conclusion Shaanxi MSM HIV infection and HIV-1 new infection were high,but HIV-1 new infection had decreased slowly.Emerging trend should continue to increase the population of the intervention ef-forts.The infection rate in other monitoring population was relatively low but a few people on the rise,the need to take the necessary coping methods.

Objective To explore the distribution characteristics of ankle-brachial index ( ABI) examination for peripheral arterial dis-ease in diabetic patients, and to provide basis for clinical diagnosis. Methods Randomly selected 110 cases of patients who were admitted into our hospital from February 2014 to January 2015, and divided them into the observation group (34 cases with diabetic lower extremity peripheral vascular lesions) and the control group (76 cases without diabetic lower extremity peripheral vascular lesions). Measured the ABI of the two groups, and analyzed the value of ABI data range for the diagnosis of diabetic lower extremity peripheral vascular lesions. Mean-while, analyzed the risk factors of peripheral arterial disease in diabetic patients according to ABI. Results The sensitivity of ABI for diag-nosis of diabetic lower extremity peripheral vascular lesions was 91. 18%, and the coincidence rate was 95. 36%, the specificity was 98. 68%, the misdiagnosis rate was 8. 82%, and the omission diagnostic rate was 8. 82%. ABI of the observation group was obviously lower than that of the control group, and the difference was statistically significant (P<0. 05). Conclusion ABI examination could be basis of clinical diagnosis and important standard of disease assessment for peripheral arterial disease in diabetic patients. It is suggested to strengthen the control of blood glucose, blood pressure and weight of patients with diabetes in order to reduce the risk of morbidity.

Objective To investigate the analgesic effect and adverse reactions of patient-controlled intravenous analgesia (PCIA) in breast cancer patients with radical mastectomy.Methods A total of 210 breast cancer patients who underwent radical mastectomy was randomly divided into two groups,experimental (group A) and control (group B) groups (n =105 cases per group).Patients in group A was used PCIA for 48 hours analgesia,while group B weas applied routine intramuscular injections of pethidine.Visual analogue score (VAS) at 4,8,12,24,and 48 hours after operation were recorded.Pulse,respiration,and blood pressure were monitored and side effects e.g.existed skin itching,nausea,vomiting,and respiratory repression were observed.Results The VAS of group A patients on 4,8,12,24,and 48 hours were2.02 ± 1.47,1.73 ± 1.38,1.68 ± 0.91,1.44 ± 0.65,and 1.21 ± 0.61,respectively;and the VAS of group B patients were 6.95 ± 1.96,6.42 ± 1.57,5.63 ± 1.66,4.99 ± 1.62,and 3.72 ± 1.46,respectively.The VAS was significantly lower in group A patients than in group B (P ＜ 0.05).The incidence of skin itching,nausea,vomiting,and respiratory repression was also distinctly decreased in group A than in group B (P ＜0.05).The overall satisfaction of patients in group A (96.2％) was remarkably higher than in group B (67.6％) (P ＜0.01).Conclusions Patient-controlled intravenous analgesia pump can more effectively alleviate the degree of pain,reduce the incidence of skin itching,nausea,vomiting and respiratory repression,improve the satisfactory degree for analgesia in breast cancer patients with radical mastectomy compared to traditional intramuscular way.
