Objective To study the preventive and therapeutic effects of ginkgo biloba extract 761 on disused skeletal muscle atrophy by observing its effects on the wet weight, protein content and contraction of the gastrocnemius of fixed hindlimb in rats. Methods 24 SD rats were divided into blank group, contrast group and experimental group. Their right hind limbs were fixed for 4 weeks with plastic plaster from metatarsus to 1 cm up the knee. The knee joint was fixed in 100? flexion and the ankle joint in 60? plantar flexion. Rats in the contrast group were perfused with 3mL distilled water, and rats in the experimental group were perfused with ginkgo biloba extract 761 (120 mg/kg, 14 mg/mL). The whole gastrocnemius muscle of the right hindlimb was dissected 4 weeks later to measure its contract tension, wet weight and protein content. Results Compared with the blank group, single maximal contraction, maximal tetanus, wet weight and protein content of the gastrocnemius muscle in the contrast and experimental groups decreased significantly (P

Objective To present and summarize the data concerning the treatment and prognosis of acute limb arterial embolism in West China Hospital.Methods Forty three patients with 52 limbs of acute arterial embolism were treated in West China Hospital from January 2003 to March 2006.There were 15 males and 28 females,aging from 26 years to 77 years 〔(58.88?13.90) years〕.The diagnosis was based on clinical manifestations and results of color Doppler sonography or DSA.The follow-up ranged from 1 month to 39 months.The following factors,which might influence the prognosis,were analysed through multiple linear regression of SPSS 10.0:age,sex,uper limb or lower limb,location of embolus,ischemic time,clinical categories of acute limb ischemia,history of smoking,atherosclerosis and other combined diseases,pervious history of acute limb arterial embolism,operative or nonoperative treatment,and postoperative complications.Results Clinical categories of acute limb ischemia include:Ⅰ(n=0),Ⅱa(n=16),Ⅱb(n=29),Ⅲ(n=7).The ischemic time varied from 3 h to 2 weeks.The sources of embolus:heart(n=39),vessle(n=7),iatrogenic origin(n=1),unidentidied origin(n=5).The therapies included embolectomy(n=38),catheter-directed thrombolysis(n=2) and medical treatment(n=12).The following postoperative complications occured:compartment syndrome(n=12),respiratory failure(n=3),alkalolsis(n=3),acute renal failure(n=2),wound infection(n=2) and pulmonary infection(n=1).Two patients died of cerebral infarction in hospital and one patient died of heart failure 3 months after discharge.Thirty-eight patients with 45 diseased limbs were followed up.The results were excellent in 13 limbs,good in 15 ones,fair in 8 ones and poor in 9 ones.The statistically significant influencing factors of prognosis include ischemic time,clinical categories of acute limb ischemia and history of smoking(P

AIM: To investigate the status of myopia in students from different kinds of schools in Shantou city, China.
METHODS: In this cross-sectional study, 2 418 students from 4 middle and high schools in Shantou were surveyed through randomized cluster sampling. Ophthalmic examination and auto-refraction were performed for all subjects.
RESULTS: Among all 2 394 students examined. The myopia rates for students from middle and high school were 48. 07% and 68. 28%. In normal middle school, students from rural area had lower rate of myopia than students from the urban area (χ2 = 13. 879, P<0. 01 ). Students from key rural high schools had lower rate of myopia than students from key urban high school (χ2 =175. 231, P<0. 01).
CONCLUSION:The prevalence of myopia in the middle school of urban area in Shantou was higher than rural area. The increasing rate of myopia in youngsters is correlated with study stress. In order to decrease the myopia rate, it is extremely important to improve study environment in students.

Twelve cases of Bartter's syndrome were reported and reviewed retrospectively.Usually vomiting was the first sympton in children,while fatigue was common in adults.Bartter's syndrome was characteristic of hypokalemia,metabolic alkalosis,elevations of plasma renin activity,serum angiotersinⅡand aldosterone and juxtaglomerular apperatus hyperplasia.Supplementation of potassium choloride was the main manner of therapy.

Objective To explore the clinical and pathologic characteristic of deep fungus infection under mechanical ventilation in neonate. Method The clinical datas of 18 neonates under mechanical ventilation approved with deep fungus infection by autopsy from 1985 to 2003 in our department were collected and analyzed.Results In 18 infants who survived deep fungus infection,2 cases were premature and 16 cases were mature,the birth weight and the numbers of patients were:2500 g 2 cases;Time under mechanical ventilation was 8-86 days and the average time under mechanical ventilation was 13 days. The pathogen caused deep fungus infection was Aspergillus(8/18),Candida albicans(6/18) and Mucor(4/18),respectively. The infected organ were lung(12/18),brain(2/18),liver(4/18) and gastrointestinal tract(2/18),respectively.Two of them were found been infected in lung and liver at the same time.Conclusions We must attach importance to deep fungus infection in neonate under machine ventilation.Aspergillus and Candida albicans were the main pathogen bacteria and lung was the main infected organ of neonatal deep fungus infection.Early diagnosis may be the efficiency approach to increase livability.

Objective: To analyze the information of patients with acute myocardial infarction (AMI) in a single center during last 6 years, and to distinguish the clinical differences of patients between TakoSTubo cardiomyopathy (TTC) and ST-segment elevation myocardial infarction (STEMI). Methods: A total of 1042 consecutive patients with primarily diagnosed acute anterior ST-segment elevation (STEMI) admitted in our hospital from 2008-01 to 2014-04 were retrospectively enrolled. The relevant patients were studied in 2 groups:TTC group, the patients with coronary angiography (CAG) and the contrast study of left ventricle corrected TTC diagnosis, n=10, and STEMI group, the patients received CAG within 6 hours of on set with conifrmed left anterior descending singlevessel disease at the same period of time as TTC patients,n=32. The basic clinical characteristics, levels of blood lipids, MI related biomarkers, the incidence rate of pathological Q wave, QTc interval and negative T wave in 12-lead ECG were compared between 2 groups. Results: The percentage of corrected TTC diagnosis in patients with primarily diagnosed STEMI was 1.06%. The female gender in TTC group and STEMI group was 100% vs 9%,P<0.01, TTC group had more patients with stress history before on set than that in STEMI group (70% vs 22%,P=0.02), lower levels of MI related biomarkers as CK (486 ± 249) U/L vs (716 ± 132) U/L, CK-MB (13.5 ± 17.1) mg/L vs (47.5 ± 21.9) mg/L, cTnI (22.8 ± 16.3) ng/mL vs (56.4 ± 24.0) ng/mL, allP<0.01. The age of morbidity, the ratios of hypertension, diabetes mellitus and blood lipids were similar between 2 groups. The frequency of abnormal Q-wave in ECG was similar between 2 groups, while the QTc interval was different in TTC group and STEMI group (630 ± 117) ms vs (540 ± 62) ms,P=0.001, the negative T waves in ECG leads II, III, aVF, aVR and V6 were as (100.00% vs 3.13%), (60.00% vs 6.25%), (90.00% vs 3.13%), (100.00% vs 21.88%), (100.00% vs 46.88%), allP<0.05. Conclusion: TTC patients with the main presentation as ST-segment elevation are usually having emotional or physical stress before on set, with obviously prolonged QTc interval and more frequency of negative T waves in ECG.
