Objective To explore the current status of physical exercises of patients with primary hypertension and provide basis for selective nursing intervention. Methods Investigation was carried out in 238 patients patients with primary hypertension in a third-grade and first-class hospital in Guangzhou on their physical exercises using the theory of "periodic behavior changing model". The results were ana|yzed. Results Patients who didn't plan to take physical exercises account for 19.3%,who planned to take it was 15.1%,who prepared to take it was 20.2%,who were taking it was 8.8% and who were maintaining it was 36.6%.The age and duration of illness course significantly influence the distribution of taking exercises in different stages, P<0.05.While gender and education background were not important influencing factors. Conclusion We should pay attention to increase the recognition of patients with primary hypertension to take physical exercises autonomously,especially the young and middle-aged patients.

Recurrent respiratory tract infection (RRTI) is a common chronic respiratory disease of children.The pathogenesis is complex,etiology and treatment methods are varied.Probiotics are immune modulators with extensive clinical application.This paper reviewed the changes of intestinal microflora in children with recurrent respiratory tract infection and the mechanisms of probiotic treatment including intestinal flora regulation,intestinal mucosal barrier,stimulation of the growth of intestinal mucosa and immune regulation.

This article explored professor Wang Qingqi's clinical experiences in treating gastroesophageal reflux disease(GERD) with traditional Chinese medicine(TCM).According to clinical observation,the key pathogenesis of GERD is abnormal rising and falling of vital energy,presenting in the five aspects of incoordination between the gallbladder and stomach,incoordination between the liver and stomach,stagnation of liver-qi with deficiency of the spleen,weakness of the spleen and stomach and qi-stagnancy and blood stasis.It will get a good curative effect when adopting the TCM methods of acrid-release and bitter-downbearing therapy,worm-like paired Chinese material medica and the opposite complementary relationship therapy.

Objective To evaluate the role of mierosurgery in surgical treatment to urethrocutaneous fistula after urethroplasty in hypospadias and improve surgical results.Methods From 1999 to 2006,44 urethrocutaneous fistulae (more than 3mm in diameter) after urethroplasty for hypospadias in 33 patients were repaired with different skin flaps.For example,Thiersch technique,urthroplasty,etc.Microsurgical tech- nique was employed in every case.Results The success rates of different procedure were 84.8% (28/33) for Thiersch technique,100% (11/11) for urethroplasty respectively.The total success rate was 88.6%(39/ 44).Conclusion It's just application of skin flap for repairing of big or complex urinary fistula after hypos- padias surgery.The application of microsurgical technique can increase success rate.It is necessary to excise scar and partial urethra for hypospadias fistula combined with urethral structures,cicatricial eontracture and in- curvation of penis.Rich blood-supply,low tension and atraumatic technique are all very important to improve surgery success rates of urinary,fistula after hypospadias repair.

Objective To investigate the status of knowledge and performance on Chinese Heart Failure Diagnosis and Treatment Guideline (2014 version) in general practitioners of Shanghai Pudong communities.Methods The survey was conducted from April to June in 2014 with a self-designed questionnaire.Total 390 general practitioners (GPs) in Pudong New Area were selected by cluster sampling method.The contents of questionnaire included:diagnosis and differential diagnosis,drug therapy,non drug therapy of chronic heart failure.Result Total 385 questionnaires were retrieved with a response rate of 98.7％ (385/390).The results showed that in aspect of diagnosis and differential diagnosis,373 (96.9％) Gps made the diagnosis based on history and physical examination,171 (44.4％)Gps never used BNP or NTPro-BNP tests,280 (72.7％)GPs did not know how to identify systolic or diastolic heart failure,86 (22.3％)Gps made the differential diagnosis according to the EF value.In aspects of drug therapy,the rate of beta blockers use was 10％-30％ in 284 (73.8％) Gps,149 (38.7％) Gps did not use beta blockers because of not knowing the contraindications,289 (75.1％) Gps used a maximum dose of betaloc for 25-50 mg,no one used 101-200 mg,242 (62.9％)Gps did not know the target dose of betaloc,the rate of ACEI/ARB use was 10％-30％ in 330 (85.7％) Gps,258 (67.0％) Gps would increase the dose but not knowing the target dose.The main reason for not using the target dose of Betaloc and ACEI/ARB was not knowing the dose.In aspect of non-drug therapy:240 (62.3％)Gps never heard of cardiac resynchronization therapy (CRT) and 271 (70.4％)Gps never heard of implantable cardioverter defibrillator (ICD).The senior rank GPs grasped the guideline much better than Gps with primary and intermediate professional ranks.Conclusion General practitioners in community health centers should further study the guideline of heart failure,particularly need to strengthen the knowledge and ability of drug therapy.

Objective To identify the expression of a fusion gene GCA formed from GM-CSF gene and LMP2A gene of Epstein-Barr virus (EBV) in a recombinant BCG (rBCG) and to study its immunoge-nicity.Methods The rBCG was constructed to express the fusion gene GCA and the expressed products were detected by Western blot assay .ELISA was performed to measure specific antibody titers in serum sam-ples from mice immunized with rBCG .Lactate dehydrogenase assay was used to analyze the cellular immuni-ty of mice.A mouse model of EBV-positive gastric carcinoma was established to evaluate the therapeutic effects of rBCG.Results The target proteins of GM-CSF and LMP2A were successfully expressed in rBCG . The specific antibodies were detected in rBCG immunized mice as indicated by ELISA .The maximum anti-body titer reached 1 ∶27 900 [(326.5±7.8) pg/ml] as injection with rBCG 5×108/mouse.The rBCG in-duced cytotoxicity of cytotoxic lymphocytes (CTLs) to EBV-positive gastric carcinoma cells (GT39) (with a killing rate of 89.6%±6.8%) was significantly higher than that of control group (P<0.05) The sizes of tumor in PBS control group [(1964.0±548.7) mm3] and BCG group [(1268.65±72.4) mm3] were big-ger than those in rBCG group [(168.64±78.80) mm3].Conclusion The rBCG expressing GM-CSF and LMP2A fusion gene was successfully constructed .The rBCG could induce humoral and cellular immune re-sponses in mice and inhibit the growth of tumor .

Objective:To explore the effect of ligustrazine on Th17 cell and the expression of Th17/Treg characteristic cytokines in a model of asthma.Methods: Male BALB/c mice were randomly devided into four groups , including the normal control group,the model group,the ligustrazine treatment group and the DXM treatment group ,with 10 mice in each group.In the model group, mice were sensitized with the OVA respectively.In the treatment group ,mice were also sensitized and challenged as model group and in addition were intraperitoneally injected with the ligustrazine or DXM.The mice of control group were intraperitoneally injected normal sodium instead of OVA and challenged by inhaling normal sodium instead of OVA in challenge phase respectively .Animals were sacrificed to detect the percentage of CD 4+CD25+T regulatory cells and Th17 cells in the blood were measured by flow cytometry ,and the cytokines,including IL-17 and IL-10,in the blood serum by ELISA.Results:The mice of model group showed the performances of a typical asthma.In treatment group ,the symptoms above mentioned became lighter.The mice of control group were generally in good condition;the lung tissue from the mice of model group showed widen alveolar septum , narrowed bronchial lumen , thicken bronchial wall,and numerous inflammatory cells infiltrated around the small vessels and bronchioles.In ligustrazine treatment group, the pulmonary inflammation was obviously relieved compared with the model group;the percentages of CD 4+CD25+T regulatory cell both in the peripheral blood and in the total CD 4+T cells were significantly lower in the mice of model group than in the mice of control group , and were higher in the treatment group than in the model group;the level of IL-10 in serum was significantly lower in the model group than in the control group ,and was higher in the treatment group than in the model group.The level of IL-17 of serum was significantly higher in the model group than in the control group , and was significantly lower in the treatment group than in the model group.Conclusion:Ligustrazine can adjust the Th 17/Treg balance and reduce the inflammation of lung tissue in asthma mice by up-regulating CD4+CD25+T regulatory cell and then restraining the Th 17 response , and play a preventive/control asthma attack role in asthma model mouse.
