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 characteristics of Helicobacter pylori(Hp)infection in community patients. Methods:In July 2020,Three hundred and sixty outpatients with Hp infection confirmed by 14C breath test from August 2018 to July 2019 in Pengpuxincun community health service center of Jing′an District of Shanghai were selected by simple random sampling for a questionnaire survey. The contents of the questionnaire included general information, symptoms of digestive tract, awareness of disease hazards, frequency of dining out, Hp infection in family members. A total of 335 valid questionnaires were collected with a response rate of 93.06% (335/360). Results:Among 335 cases of Hp infection, 282 cases had clinical symptoms and 53 cases had no clinical symptoms. The infection rate of family members of Hp infected patients with and without clinical symptoms was 55.67% (157/282) and 56.60% (30/53) respectively (χ2=0.016, P>0.05). Belching was the most common symptom(27.09%,175/646), followed by abdominal distension(22.45%,145/646), acid reflux (17.03%,110/646), abdominal pain(14.86%), halitosis(14.55%). There was no significant difference in the frequency of halitosis, acid regurgitation, belching, abdominal distension and abdominal pain among the three groups(χ2=13.297, P>0.05). The Hp infection rate of family members with frequent or seldom out dining was 82.40% (103/125) and 40.00% (84/210), respectively, (χ2=57.122, P<0.05). The awareness rates of Hp hazard in patients with educational levels of primary school and below, junior high school, senior high school and junior college and above were 9.43% (5/53), 51.55% (50/97), 62.50% (65/104) and 87.65% (71/81), respectively(χ2=82.447, P<0.01). There was no significant difference in the age distribution between males and females (χ2=1.155, P>0.05). Conclusion:It is necessary to strengthen the health management of Hp infected people and improve the awareness of Hp infection hazards among community residents to reduce Hp infection rate in the community.

Major depression disorder is an increasing heavy burden in modem society, but its pathological mechanism is still vague. Recent evidence indicated that two pore potassium channel, TREK1, is one of the important drug targets of antidepressants. The structural and functional research progress of TREK1 potassium channel were reviewed with an emphasis on its roles in anti-depression, neuronal protection, and neuronal plasticity. The complicated interactions between TREK1 potassium channel and monoamine transmitters-receptors were also reviewed and future directions to explore the underline mechanism were also discussed.

Objective To analyse the clinicopathologic factors affecting prognosis and fertility of patients with malignant ovarian germ cell tumor (MOGCT).Methods The medical records and follow up data of 106 patients with MOGCT treated at Affiliated Tumor Hospital of Guangxi Medical University between January 1986 and December 2010.Kaplan-Meier method was used to analyse survival curves.The different prognoses between different clinicopathologic factor was evaluated by univariate analysis and log-rank test.The multivariate analysis was performed by the Cox proportional hazard regression method.Logistic regression analysis was used to evaluate the influence of different factors on the prognoses and fertility.Results The median age at primary treatment was 22 years old (range:9-61 years old),59 patients received fertility-preserving surgery,45 patients received radical surgery,only 2 cases performed biopsy; 94 patients received postoperative adjuvant chemotherapy.Median follow-up time was 56.5 months (range:2-309 months),there were 11 cases recurrences,23 cases died from cancer.Of 47 patients live without tumor,45 patients had normal menstrual.Of the 39 patients desiring pregnancy,31 cases got 33 successful pregnancies,resulting in 33 live births.There is no statistically significant difference (P ＞0.05) in progression free survival (PFS ; 67.6％ versus 63.3 ％) and overall survival (OS ; 70.0％ versus 64.1％) and mortality [15％ (9/59) versus 31％ (14/45)] between fertility-preserving surgery patients and radical surgery patients.The univariate analysis showed that the pathological types,postoperative residual tumor size,lymph nodes and omental resection were associated with OS (P ＜ 0.1),and postoperative residual tumor size,chemotherapy cycles,lymph nodes and omental resection were associated with PFS (P ＜0.1).The multivariate analysis showed only the postoperative residual tumor size was independent prognostic factor of OS (P =0.039),and postoperative residual tumor size,chemotherapy cycles,lymph nodes resection were independent prognostic factors of PFS (P ＜ 0.05).There is no statistically significant difference in OS,PFS and fertility between fertility-preserving surgery patients treated with or without a comprehensive staging surgery (P ＞ 0.05).Conclusions MOGCT can achieve a good prognosis after surgery combined chemotherapy.Postoperative residual tumor size is independent prognostic factor of PFS and OS.Comprehensive staging surgery could not improve prognosis.Fertility-preserving surgery plus adjuvant chemotherapy appeared to have little or no effect on prognosis and fertility.
