Objective To observe the curative effects of Jawei-Wendan decoction in treating acute exacerbation of COPD due to phlegm blocking in lung. Methods From July 2010 to June 2013, 66 enrolled cases were randomly divided into a treatment group and a control group with 33 in each. Aside from receiving anti-infection and symptomatic treatment as the control group did, the treatment group was also given orally Jawei-Wendan decoction. The symptoms, pulmonary function and the variety of the laboratory indexing were observed before and after the treatment. Results ①The treatment group attained better curative effects(P<0.05) and got shorter symptomatic relief time of cough, expectoration and breathless(The T-value is respectively 16.770, 8.635, 16.762, P<0.05). ②After 7-days treatment, the cure rate of the treatment group was 63.64%, and the control group was 39.39%. Their difference was conspicuous(P<0.05). The total effective rate in treatment group was 96.97%, which was 90.91% in control group. Their difference was inconspicuous(P>0.05).③The pulmonary function indices increased significantly in the treatment group[The values of FEV1、FVC and FEV1/FVC% are (1.41±0.46)L, (2.18±0.63)L and (66.41±6.33)% before treatment, which were (2.21± 0.55)L, (2.83±0.53)L and (77.37±7.64)%after treatment, P<0.01]. A comparison of the two groups showed significant differences regarding the pulmonary function indices(P<0.05). Conclusion Jawei-Wendan decoction had good curative effect in treating acute exacerbation of COPD due to phlegm blocking in lung.

BACKGROUND: Inhaled glucocorticoids(IGC) are powerful anti_inflammatory agents used in the treatment of asthma. But it is still uncertain whether long-term use of the IGC affects bone metabolism in asthmatic patients, especially women.OBJECTIVE: To investigate if the prolonged treatment with IGC to Chinese asthmatic woman has a detrimental effect on bone mass and metabolism.DESIGN: A matched controlled study based on the patients SETTING:Clinical Laboratory and the Department of Respiratory Medicine, First Affiliated Hospital, Nanjing Medical University.PARTICIPANTS: From February 1998 to February 2002, forty female Chinese patients with bronchial asthma, regularly followed up at our outpatient clinic, all in the Nanjing area, none of them having a history of chronic systemic GC use, agreed to take part in the study, were selected and divided into two groups: therapeutic group (IGC group): 20 asthmatic women, aged 18-63 years, 5 menopausals, received IGC therapy regularly for at least 5 months; Control group: 20 asthmatic women, aged 18-60 years, 5 menopausals, never received IGC received conventional bronchodilators . They were matched individually for sex, age and menopausal status.METHODS: Bone mineral density (BMD) at the lumbar spine (2-4),femoral neck, trochanter, ward's triangle and total body of femur were measured by dual energy X-ray absorptiometry, BMD were expressed as a absolute value and a T score considered as a SD from peak bone mass respectively. Meanwhile, BMD was also expressed as a percentage (%), which was defined by comparing the BMD absolute value of subjects and BMD normal value of isosexual age cohorts. Osteocalcin and some other markers of bone metabolism were measured by radio immunoassay in two groups.daily dose and accumulative total dose of IGC and BMD in the IGC group.RESULTS: There were no significant difference between two groups in BMD and T score (including the lumbar spine (2-4), femoral neck,trochanter, ward' s triangle and total body of femur) (P ＞ 0.05). There were also no significant correlation between daily dose of IGC and BMD of above 5 parts in the IGC group (r=-0.325 to -0.1102, P ＞ 0.05). But,there were significantly negative correlation between the accumulative total dose of IGC and BMD at lumbar spine2-4,femoral neck and ward's triangle(r=-0.495 ,-0.517,-0.531 ,P ＜ 0.05).There were no significant correlation between the accumulative total dose of IGC and T score of above 5 parts in the IGC group (r=0.443to 0.295 ,P ＞ 0.05). There was negative correlation between the age and the BMD at ward's triangle in the IGC group(r=-0.506,P ＜ 0.05). However ,BMD at 5 locus were not correlated with the age in control group (r=-0.079 to 0.326, P ＞ 0.05).Osteocalcin and some other markers of bone metabolism were no significant difference between two groups (P ＞ 0.05).CONCLUSION: The data suggests that there is no significant influence of IGC on bone mineral density and bone metabolism in asthmatic women,but if continuing exposures to high doses over many years,there may be a detrimental effect on bone mass and metabolism in women, especially elder or postmenopausal asthmatic women treated with IGC who may be more susceptible to any bone mineral loss caused by IGC.

CONCLUSION: The expression vector of recombinant plasmid pEGFP-NGB was successfully constructed and green fluorescence protein was expressed in cultured neuroglial cells.

Objective To research the possible influence of operation and human chorionic gonadotropin(HCG) therapy on the development of antisperm antibody (AsAb) and serum levels of estradiol (E_2) and testosterone (T) of cryptorchidism boys after orchiopexy. Methods Forty cryptorchidism boys were studied who were divided into HCG treatment group and without HCG treatment group. Twenty boys who underwent inguinal operation were studied as the operation control group and 20 normal boys as the control group. The serum were collected for detection AsAb, E_2,and T. Results There were no significant difference in serum levels of E_2 and T among the three groups(P 0.05 ). Conclusions The level of AsAb is associated with the destroy of blood barrier and the disorder of immune modulation and endocrine. Treatment with HCG has no effect on AsAb level.

Objective To investigate outpatients' cognition towards common cold and their habituated medication so as to provide evidence for future public healthcare education.Methods Patients who attended hospital for diagnosis and treatment of common cold at least within past three months were asked to fill a questionnaire independently so as to learn their cognition towards common cold and medication habit.Results Among the patients underwent survey,52.2 ％ had incorrect knowledge about common cold; 2.99％ didn't know about the hazards of common cold; 34.80％ couldn't distinguish common cold from influenza; 30.07％ considered common cold couldn't get relief without treatment; 68.24％ didn't know about the proper effects of influenza vaccination; 6.4％ often took oral medicine even intravenous injection when they caught a common cold; 59.77％ often took medication from drugstore without prescription by doctor,and a few asked doctors to prescribe medicine on their request; 9.42％ didn't know about the side effects of drug for cold treatment; and 9.72％ didn't know about the active ingredients of drug for cold treatment.There were significant differences in the common cold cognition among population of different ages and education background.The older or the higher education status patients had a better cognition ( P ＜0.0 ).Conclusion There exist a certain degree of wrong cognition towards common cold among patients of different literacy degree and different age. Public health education on common cold need to be further strengthened.

Objective To investigate the cognition of the common cold and current situation of the treatment among physicians from various levels of hospitals in Chinese mainland,so as to provide evidence for future continuing medical education and rational medication.Methods A questionnaire designed for this survey was used to learn about the general information,cognitive degree of the common cold and prescription habits of physician who prescribed for cold within last three months,from various levels hospitals.Results A total of 1001 physicians were interviewed.Among them,749 physicians chose right options that the cold was the common cold and the influenza with 79.84％ in resident physicians and 56.76％ in chief physicians.A total of 745 physicians chose options that the course of common cold will be lasting 4 to 7 days; 895 physicians chose options that old people are the most susceptible for complication; 669 physicians thought the common cold was the most common infection in winter; 841 physicians used clinical methods to diagnose the common cold; 736 physicians thought although the cold was a kind of self-limited disease and symptomatic treatment could alleviate symptoms and improve life quality,patients should see doctor in time if it turns to severer; and 745 physicians held the opinion that treatment of the common cold should focus on relieving symptoms first. In addition, 61.60％ physicians had made prescription based on clinical symptoms; 505(54.24％ ) of them thought compound drugs were priority in treating the common cold.However,there were still 43 physicians prescribed antibiotics for common cold.Conclusions There is misunderstanding and discrepancy in cognition towards common cold and treatment among physicians from various levels of hospticals in mainland China.Physicians should standardize diagnosis and treatment for the common cold according to the domestic and foreign guidelines.

Objective:To understand the needs, problems and challenges of medical personnel in the hospital for scientific research, propose tailored management measurements and suggestions for the hospital.Methods:The questionnaire was prepared by " Questionnaire Star" , the convenience sampling method was used, and information was collected by WeChat online chat group. Factor analysis and multi-dimensional preference analysis were adopted to analyze information collected.Results:Four main factors that affect the scientific research of medical personnel were identified. The most significant impact is the lack of information platform, followed by the lack of environmental atmosphere, lack of personal capacity and lack of personal interest. The research needs of medical personnel are divided into two categories: one is the more basic skill needs, which are mainly targeted at female, nurses, undergraduates, 5~10 years′ working experiences, medium-grade professional title, and people with no knowledge and experience in research. The other one is the needs of skill improvement, which are mainly targeted at younger, physicians, early career, lower professional titles, and had certain research knowledge.Conclusions:So far, there is a lot of space for improvement. It is recommended to promote the capacity building by training, strengthen the research team building and construct of research communication platform, at the same time, update the scientific research management system.

OBJECTIVETo measure uric acid of seminal plasma in fertile and infertile males.

METHODSOne hundred and sixty-three infertile males were divided into an obstructive azoospermic group (15 cases), a non-obstructive azoospermic group (36 cases), an oligozoospermic group (43 cases), and an asthenozoospermic group (69 cases). Twenty fertile males were included in the control group. Uric acid concentrations of seminal plasma in the fertile and infertile men were assessed by spectrophotometer, and sperm parameters were analyzed by computer-assisted semen analysis (CASA) system.

RESULTSUric acid concentration of seminal plasma in the control group was significantly higher than all the infertile groups (P < 0.01), and that of the obstructive azoospermic group significantly lower than the other infertile groups (P < 0.1), but no significant difference was observed among the other infertile groups (P > 0.05).

CONCLUSIONUric acid may play an important role in male reproduction because of its antioxidative property.

Objective To study the relationship between bronchial asthma and smoking status in Chinese people.Methods Asthma epidemiological survey and stratified-cluster-random method survey were performed in residents over 14 years in 8 provinces (cities) of China from February 2010 to August 2012.Asthma was diagnosed based upon case history,clinical signs and lung function test.Smoking status was investigated by questionnaire.Results Sampling population was 180 099 and 164 215 were valid.A total of 2 034 subjects were diagnosed as asthma including 79 692 men and 84 523 women.The overall prevalence rate of asthma was 1.24％ (2 034/164 215).Smokers were 23.8％ (39 137/164 215) in the whole population.Smokers were 34.5％ (702/2 034) in asthmatic patients,compared with 23.7％ (38 435/ 162 181) in no-asthmatic population.The incidence of asthma was 1.79％ and 1.06％ in smokers and nonsmokers respectively (P ＜0.001),suggesting that OR of smoking was 1.70 (95％ CI 1.55-1.86,P ＜ 0.001).According to asthma control test (ACT) score,the level of asthma control in non smoking group was higher than that in smoking group(43.2％ vs 35.3％).The times of hospitalization due to acute exacerbations (0.51 vs 0.41 events/person/year),total hospitalization rate (27.35 ％ vs 20.12％),annual emergency room visits (0.80 vs 0.60 events/person/year) and emergency room visit rate (31.77％ vs 24.47％) were all much higher in smoking asthmatic patients than those in non smoking asthmatic patients,indicating that the level of asthma control in smoking patients was significantly worse than in non smoking patients.Conclusions The smoking rate in Chinese people over 14 years is still high.The prevalence rate of asthma in smokers is significantly higher than that of non-smokers.The level of asthma control in smokers is significantly worse than that in non smokers.

BACKGROUNDLittle is known about asthma control and perception of asthma among asthmatic patients in China. This study marked the first survey conducted on a national scale that aimed at obtaining baseline information on asthma control and patients' perception of asthma and providing a point of reference for future studies.

METHODSThis face-to-face, questionnaire-based survey was conducted from April 2007 to March 2008 with 3 069 asthmatic patients from the respiratory outpatient clinics of 36 general hospitals located in 10 geographically dispersed cities.

RESULTSConsistent with the Global Initiative for Asthma (GINA) guidelines, 28.7% and 45.0% of our patients achieved control and partial control, respectively. Of the patients in the study, only 21.8% had used a peak flow meter (PFM), and 6.6% of these patients used it daily. Inhaled corticosteroids (ICS) plus a long-acting β2 agonist (LABA) and ICS were the two most common medication regimens and were used in 45.6% and 30.4% of patients, respectively. Asthma had a significant effect on the patients' life and work. A considerable number of hospitalizations, emergency department visits, and sick days were observed.

CONCLUSIONDespite improvements in asthma control and ICS and PFM compliance compared with past literature, the current level of asthma control countrywide continues to fall short of the goals set in the GINA.
