Vasovagal syncope (VVS) is the most common cause of transient loss of consciousness ( TLOC ),mainly with head-up tilt test (HUTT) for diagnosis and treatment evaluation.Beacause of potential risks in the process of HUTT,it is necessary to explore an early,accurate,safe,effective,inexpensive and convenient means of diagnosis and evaluation for VVS.The means of quantitative history are now in practice of clinical trials.The means commonly used are Calgary Presyncope Form (CPF)and three questionaires about point scores in the Calgary syncope symptom studies.Due to its stable,simple and easy to apply features,CPF has some advantages on assessing the effectiveness of different treatment methods for VVS.The three questionnaires have some application potential in diagnosis for VVS.

Autonomic nervous system(ANS) activity plays an important role in the pathogenesis of cardiovascular disease,including organic cardiovascular disease(such as hypertension,coronary artery disease,etc) and functional cardiovascular disease (such as vasovagal syncope,postural orthostatic tachycardia syndrome,etc).Many methods was used to evaluate ANS function.Heart rate variability is a widely accepted method to assess cardiac autonomic nerve function.Autonomic nervous affected cardiac action potential and let electrocardiogram changes.Through the sympathetic and parasympathetic neurotransmitters which acting on the corresponding receptors.Electrocardiogram changes reflects autonomic nervous function.Present researches suggest that electrocardiogram has an important significance in the evaluation of autonomic nerve function in functional cardiovascular disease.

Objective To establish the quality standard of charred Radix et Rhizoma Rhei. Methods Kromasil-C18 column (4.6 mm?150 mm, 5 ?m) was used with mobile phase of methanol-0.1% phosphate acid (85∶15), 1.0 mL/min, and detection at 254 nm. Result Average recoveries of charred Radix et Rhizoma Rhei: Emodin was 98.43% and Chrysophanol was 98.32%, RSD was 1.17% and 1.02% respectively. Conclusion This method is simple. The result is accurate and reproducible. It can be used in the study of the processing technics of Radix et Rhizoma Rhei and the quality control of charred Radix et Rhizoma Rhei.

[Objective] To study the mechanisms and effects of panax notoginsenosides(PNS)on myocardial fibrosis in chronic viral myocarditic(VMC)mice.[Methods]The model mice with VMC at chronic status were established by repetitive infection of Coxsckievirus B3m(CVB3m).Heart changes of myocardium and collagen hyperplasia were observed by HE and VG stain.Collagen volume fraction(CVF)and perivascular circuferential area(PVCA)were examined by pathological examination with computed processing.Myocardium TGF-?1 was detected by immunohistochemical method and mRNA expression of TGF-?1 was analyzed by Reverse transcription polymerase chain reaction(RT-PCR)method.[Results]Marked myocardial fibrosis was observed in chronic VMC model group.Compared with blank group,the index of CVF and PVCA was increased significantly(P

Objective To establish quality standard for prepared slices of salt-processed psoralea corylifolia.Methods Psoralen and isopsoraten in the crude psoralea corylifolia and its salt-processed products were determined by traditional identification,thin-layer identification and HPLC method.Water,ash,extract,pesticide residue and heavy metals were also detected.Results The average content of total content determination for psoralen and isopsoraten in more than 10 patches of crude and processed samples was not below 0.5% and 0.6% respectively.Conclusion HPLC method is simple and the result is reliable with good repeatability and can be used for the determination of the components in psoralea corylifolia.The quality control standards of the psoralea corylifolia is normative,systematic and the result is accurate.

The enrollment physical examination,as a real assessment of the physical and health condition for those high school graduates,is of great referencing significance for their major selection.Therefore,during the examination process,medical staff involved should enhance their recognition for relevant legal regulations,and fully respect graduates′ rights of privacy and informed consent,to ensure the impartiality,fairness,reality,and effectiveness of the assessment result,and guarantee the legal rights of high school graduates.

The paper sums up quality management in obstetrics in Shanghai in the past 10 years and gives an account of the specific measures adopted: laying a solid foundation of quality management in obstetrics and creating a sound organizational framework;valuing the crux of quality management in obstetrics and strengthening the control of process quality;stressing quality improvement in obstetrics and the analysis and feedback of outcome information and guiding the formulation of short-term and long-term action plans.It also describes the marked results obtained,including a reduced maternal mortality rate,enhanced access criteria for maternity hospitals,and preliminary results attained after the establishment of maternity hospitals for women from other areas.In addition,the paper puts forward suggestions for further improving maternal healthcare and obstetric quality.

Nephrotic syndrome(NS)is the most frequent cause of glomerular disease in children,it can deve-lop many complications,including infection,thrombosis and acute kidney injury,while acute adrenocortical suppression is a complication of some drugs administration. This review focuses on the pathophysiology and management of common complications in patients with NS.

Objective To investigate the surgical techniques and clinical effect of laparoscopic improved myomectomy. Methods After the surgical techniques and instruments were improved, laparoscopic myomectomies were performed in 91 patients with uterine myoma. The maximum diameter of myoma was (60 4?11 9) mm (range, 25 mm～110 mm), and in 35 cases the myomas were ≥7 0 cm and in 56 cases 0 05). Conclusions After the surgical techniques and instruments were improved, the operation time and the blood loss can be reduced, and better clinical effect obtained, even in patients with somewhat larger uterine myoma.
