Objective To analyze the epidemiology of the emergency medical service in Urumqi City in 2011.Methods All patients from 120-Ambulance Center of Urumqi City admitted from January 1,2011 through December 30,2011 were enrolled for prospective study.Descriptive analysis the gender,age,race,underlying diseases,the peak of calling,the time taken by ambulance and so on.Results The 120-Ambulance Center answered overall 53786 callings,the callings of effective answer were 47260,while the ineffective answers were 6526 accounting for 13.8％,and the average number of answer per day was 147.The ratio of male to female was 1.61:1 ; the number of callings from Han nationality was predominant accounting for 68.87％ (37043 callings),and the number of callings from Weiwuer nationality was next to that from Han nationality.The five most common emergency problems were traffic injury,acute cardiovascular diseases,cerebro-vascular diseases,trauma and poisoning.There was no significant difference in monthly number of emergency cases during the 12 months of 2011,and the average monthly number of emergency cases was ranged in 2500-3500.The peak time of answering occurred in 10:00 am-13:00 pm、16:00 pm-18:00 pm、21:00 pm-24:00 pm; the ages of patients were dominant in the population of 20-29 years old、30-39 years old and 70-79 years old.Conclusions We should lay the emphasis on the most common diseases,the peak of answering,and the most vulnerable population,in order to come across with the theoretical and practical evidence to the relevant public health bureau for the improvement of transport mode carried out by 120-Ambulance Center in Urumqi City.

Objective To investigate the curative effect of different biofeedback and electrical stimulation solutions on female stress urinary inconti-nence(SUI). Methods A total of 40 female patients with mild-to-moderate SUI were randomly divided into two groups(n=20 each group)and treated by the biofeedback and electrical stimulation. In the treatment group,the current increased in the middle of the treatment on the basis of the initial threshold of stimulus intensity to make a new tolerable threshold of stimulus intensity. In the control group,the patients were treated with the initial threshold of stimulus intensity during the whole treatment. The curative effects in these two groups were determined by the comprehensive strength of pelvic floor,the 1 h urine pad test results,and the life quality scores of urinary incontinence. Results After treatment,there were signifi-cant improvements in all the above indicators in two groups(P<0.05),and the results is better in the treatment group than in the control group. The effective rate in treatment group(95%,19/20)was higher than that in the control group(65%,13/20)(P<0.05). Conclusion The biofeedback and electrical stimulation were effective and safe in the treatment of women with SUI. The curative effect of patients treated with increasing current in the middle of the treatment is better,suggesting that it can be widely applied in clinic.

Eighty two patients aged 60 or over with stable angina pectoris were randomized to control group ( n = 42, receiving conventional western medicine) and treatment group ( n = 40, receiving 1.5 g Songlingxuemaikang capsules three times a day in addition to western medicine) .The treatment was lasted for 12 weeks, angina classification of CCS, hs-CRP, blood pressure levels and SF-36 (36-item short form)of the patients were evaluated before and after the treatment.The degrees of angina pectoris in angina classification of CCS, hs-CRP and blood pressure levels decreased, and the quality of life was improved in both groups; but more markedly in treatment group than those in control group (P ＜ 0.05 ).Songlingxuemaikang capsule combined with conventional western medicine can effectively relieve the symptoms of ischemic chest pain in elderly patients with stable angina pectoris, which is associated with blood pressure reduction and life quality improvement.

OBJECTIVE To investigate the antibiotic resistance of Staphylococcus aureus isolates from the clinical samples from 2005 to 2007.METHODS The susceptibility tests and D-test were performed by the disk diffusion method and their results were analyzed by the software WHONET 5.4.RESULTS The rate of MRSA isolates accounted for 64.1%.The resistance rate to 12 kinds of the antimicrobial agents,such as penicillins,cephalosporins and carbapenems was 100%.The MRSA and MSSA were susceptible to linezolid and vancomycin.No isolates were resistant to vancomycin in our hospital;the positive rate of D-test was 78.7%.CONCLUSIONS MSSA is still sensible to most of the antimicrobial agents,but MRSA shows multidrug resistance.The D-test is of great clinical importance.

Objective To establish the extraction process of Zhechong Chuangyu Capsule.

Results There was no obvious difference in analgesic effect between water extraction and alcohol extraction. Given the requirement of produce, aqueous extraction was a better choice. The optimum extracting condition was extracted 3 times with 20 folds volume of solvent, and extraction time was 150 minutes. Conclusion The extraction process is feasible to be applied into production.

Background:Detection and removal of colorectal polyp by colonoscopy is of great importance for prevention of colorectal carcinoma. Aims:To investigate whether the clinical symptoms of patients undergoing colonoscopy may hint colorectal polyp and carcinoma,and provide reference for candidate selection in colonoscopic screening. Methods:A total of 2 366 patients undergoing colonoscopy were recruited and the history information such as symptoms at outpatient visits, site and nature of the lesions was collected for analyzing the detection rates of colorectal polyp and carcinoma and the correlations of clinical symptoms with the risk and site of the disease. Results:The overall detection rates of colorectal polyp and carcinoma were 20. 5% and 5. 4% ,respectively,in 2 366 patients. The detection rates were significantly higher in symptomatic patients than those in asymptomatic patients(24. 2% vs. 4. 5% for polyp and 6. 4% vs. 0. 9% for carcinoma,P all = 0. 000). Moreover,when patients were classified by major symptoms,the detection rate of colorectal polyp was significantly increased in patients with diarrhea(OR = 1. 213),hematochezia(OR = 2. 076),and changing of stool consistency(OR = 1. 503)(P all < 0. 05),and the detection rate of colorectal carcinoma was significantly increased in patients with abdominal pain( OR = 1. 568),hematochezia( OR = 2. 837),changing of stool consistency( OR =2. 206),and tenesmus( OR = 1. 735)( P all < 0. 05). The major symptoms being hematochezia,changing of stool consistency and tenesmus were associated with lesions locating at rectum or left hemicolon(P all < 0. 05). Conclusions:Diarrhea, hematochezia and changing of stool consistency hints risk for colorectal polyp, while abdominal pain, hematochezia,changing of stool consistency and tenesmus hints risk for colorectal carcinoma. Colonoscopy is strongly recommended for patients with these symptoms.

Objective To investigate the risk factors of worsening renal function (WRF) in patients with chronic heart failure ( CHF) and WRF influence on prognosis. Methods A case-control study were undertaken to analyze independent risk factor statistically related to incidence of WRF, and to assess the influence of WRF on prognosis. Results The independent predictors of WRF were creatinine level at admission (OR 2.248,95% CI 1.088-4.647, P = 0.029) and NYHA class on admission ( OR 2.485, 95% CI 1.3854. 459, P = 0.002). The mortality of patient with WRF was obviously higher than that of control group during hospitalization( OR 3. 824,95% CI 2. 452-5. 637 ,P ＜0.015). Conclusions WRF is a common complication among patients hospitalized for CHF, and is obviously associated with mortality during hospitalization. Higher creatinine level and weak heart function are independent risk factors for incidence of WRF of patients with CHF.
