Gonadotropin releasing hormone agonists(GnRHa)are the relatively safe drugs widely used in clinic to treat precocious puberty.After therapy withdrawal,the patients would have normal menstrual onset,gestation and fertility.GnRHa didn't degrade uterus volume of post puberty.After cessation of GnRHa,luteinizing hormone,follicle stimulating hormone and sex hormone levels would return to those before therapy,or even exceed them.Some researches suggested that gonadotropin releasing hormone analogue might increase the risk of androgen excess and polycystic ovary syndrome.The researches apply no sufficient evidences to show that GnRHa had significant and irreversible negative influences on bone mineral density.GnRHa might have the side effect of increasing body mass index(BMI).However,researches also showed that GnRHa was helpful to decrease BMI,or not to increase it.

Acquired immunodeficiency syndrome (AIDS) is a serious infectious disease caused by human immunodeficiency virus (HIV). Increasing cases of HIV infection have been detected in adolescents. Intravenous drug abuse and sexual behavior, which are affected by various individual and environmental factors, are the major ways of HIV infection. The current situation and influential factors of HIV infection in adolescents are introduced in this paper.

Objective To investigate the pathogens and drug resistance of bacteria in children with pneumonia in Chongqing by using antibiotic reasonably.Methods Bacteria identification antibiotics sensitivity test were performed in samples of lower respiratory tract secretions from 780 cases by microscan automatic analysis machine.At the same time,respiratory virus,chlamydial and mycoplasmal pneumoniae were tested.Results The pathogens were found in 433 cases.Three hundred and sixty-four strains bacteria were isolated,116 cases were infected by virus and 26 cases by mycoplasmal pneumoniae.The resistant rates of staphylococcal and Klebsiella pneumoniae were high.The resistant rate of Streptococcus pneumoniae to penicillin was high.Haemophilus parainfluenzae was sensitive to cephalosporins.Conclusions In Chongqing,children′s pneumonia is mainly caused by bacteria.The sensitivity of antibiotic varies from different bacteria.Finding pathogens and monitoring drug resistance have taken great advantage to antibiotic selection and have prevented rapidly growing of resistant strains.

Objective To explore the feature of clinical and laboratory and therapy in childern with idiopathic pulmonary hemosiderlsis(IPH).Methods The clinical and laboratory datas of 50 cases with IPH were studied from Jan.1996 to Jan.2006.The hemogram,the metabolism of ferrum,the cellular test of bone marrow,finding the hemosiderin cells in sputum or gastric juice or bronchovesicular juice and ma-nifestation were analyzed.Results IPH were often found in children aged 6 to 14 years old.Coungh and spitting blood and anemia were the most important clinical feature.X-ray manifestations were various.The diagnosis of IPH was based on clinical feature and finding out the he-mosiderin cells in sputum or gastric juice or bronchovesicular juice.X-ray and CT manifestations were important.At the same time,the secon-dary IPH was removed.The clinical symptom of IPH were relieved by using adrenal cortical hormone.Conclusions There is no specificity in children with IPH.X-ray,CT manifestations and finding the hemosiderin cells in sputum or gastric juice are helpful in diagnosis.Using adrenal cortical hormone will release symptom and prognosis.

Objective To investigate clinical effect of sparfloxacin on the treatment of ureaplasma urealyticum prostatitis.Methods 96 cases with ureaplasma urealyticum prostatitis, which admitted in our hospital, were selected as the research object and divided into observation group ( n =48 cases) and control group ( n=48 cases) randomly.The control group was given the ofloxacin for treatment and the observation group was given the sparfloxacin for treatment.The clinical effect of the two groups after treatment was analyzed.Results The total effective rate of the observation group (97.92%) was significantly higher than that of the control group (72.92%) (P<0.05).After treatment, the total incidence of adverse reactions of the observation group(8.33%) compared with that of the control group (10.42%), had no significant difference(P>0.05).Conclusion Patients with ureaplasma urealyticum prostatitis, the treatment effect of sparfloxacin is significant, with lower adverse reactions rate and the security is higher, which is recognized in the medical community, can be worthy of popularization and application in clinic.

Objective To investigate the clinical effect and safety of laparoscopy on ovarian benign tumor. Methods The data of 68 patients, underwent laparoscopic operations on ovarian benign tumor from Jan 2009 to Jan 2010, were analyzed retrospectively. Sixty eight patients underwent laparotomy were randomly enrolled as control. The operative time, the blood loss, the average admission day and the average postoperative exhaust time were compared between two groups. Results We found no significant differences in the comparation of operative time ( [ 63.60 ± 7.71 ] min vs. [ 62. 40 ± 8. 90 ] min, t = 0. 663, P ＞ 0. 05 ), while the blood loss, the average postoperative exhaust time, the average admission day of the treatment group were significantly lower in the objectives than control ( [ 68.00 ± 14. 90 ] ml vs. [ 119.00 ± 19. 60 ] ml, [ 17.30 ±2.40]h vs. [34.60 ±2.80] h, [3.90 ± 1.40] days vs. [7.70 ± 1.50] days,t =2.664, 2. 523,2.724,Ps ＜0. 05). Conclusion Laparoscopy is the first choice of method in treating ovarian benign tumor given its minimal invasion and rapid recovery.

For hypertension,lowering blood pressure is the basis and well controlled pressure is the core.The ultimate goal of the therapy is to decrease the risk of target organs damage,then minimize the occurrence of cardiovascular endpoint events.Evidence based medicine has confirmed the advantage of ACEI and CCB therapy in controlling blood pressure,lowering the incidence and the mortality of coronary disease.

OBJECTIVE To understand the distribution and antibiotic resistance of the pathogens causing urinary infection among the patients with urinary calculus.METHODS Totally 406 strains were isolated from the 1244 urinary specimens.The antibiotic susceptibility of these strains was detected.RESULTS The most of pathogens were G-bacteria(348,85.7%).G+ bacteria and fungi accounted for 12.1%(49/406),and(2.2%,9/406).The most popular pathogens were Escherichia coli(54.9%),Klebsiella pneumoniae(8.1%),Staphylococcus(7.4%),Enterobacter(4.9%),and Enterococcus(3.7%).The detection rate of ESBLs was 52.5%.Meticillin-resistant Staphylococus accounted for 83.3%.Clindamycin-induced resistance of Staphloccocus accounted for 20.0%.6.7% Vancomycin-resistant Enterococcus were isolated.CONCLUSIONS G-bacteria are the most popular pathogens and show increased resistance to common antibiotics.The results of the paper will be usefal for the doctors to choose antibiotics reasonably.
