Objective To investigate the characteristics of risk factors and coronary angiography (CAG)in young patients with acute myocardial infarction(AMI).Methods A total of 36 consecutive AMI female patients (age≤44 years)who underwent coronary angiography were retrospectively retrieved from the database,and 90 AMI patients whose age >44 years who also underwent coronary angiography were enrolled as a control (elderly)group.Characteristics of risk factors and coronary angiography were com-pared between the two groups.Results The risk factors:BMI,family history of coronary heart disease and high triglycerides(TG)were major in the youth group.The percentage of single-branch lesion was lower in the young patients.The prevalence of left anterior descending (LAD)was higher in the young patients(P <0.05).Conclusions The main risk factors in young and elderly patients are significantly different.The out-comes of CAG in the young patients show the coronary lesion are mostly single vessel lesion,and early inter-vention may improve prognosis.

Objective To investigate the effects of hyperbaric oxygen (HBO) on ischemia/repeffusion (Ⅰ/R) injury of the small intestine after resuscitation from trauma and hemorrhagic shock (T/HS) in rats in order to elucidate the underlying mechanisms. Method Ninety-six male Wistar rats were randomly divided into four groups with 24 rats in each group. In shock group, rats were operated with induced T/HS. In sham group, rats operated without induced T/HS. In one HBO therapy (HBOT) group, rats with T/HS were treated with HBOT once. In three-HBOT group, rats with T/HS were treated with HBOT thrice. The Animal Care and Use Committee of China Medical University approved all animal protocols. Rats were anesthetized with amobarbital sodium (80 mg/kg, i.p.) at room temperature (25 ℃), the bloed pressure was monitored via polyethylene cannula inserted into the right femoral artery, connecting with the pressure analyzer (Multiparameter Monitor, M3046A, Boebin-gen, Germany). The left jugular vein was cannulated for administering normal saline and for resuscitation. The right carotid artery was cannulated for shedding blood. After operation, the middle part of left thigh of rat was se-lected as a site to be made of trauma by a lump of 2.5 kg iron falling upon from 20 cm height, causing the com-pound fracture of femur and crush injury of muscular tissue, then the damaged thigh was bandaged and fixed. At the same time, the blood was drawing out of fight carotid artery via cannula until the mean arterial was reduced to 30-35 mmHg within 5 minutes. The hypotension was kept constant for 60 minutes by additional drawing small amounts of blood as needed. After 60 minutes of hypotension, the rats were resuscitated by transfusing the shed blood over 5 minutes, followed by 4 -6 mL normal saline in 60 minutes to get the mean artery pressure maintained above 80 mmHg. The resuscitated rats were put into the hyperbaric chamber (10N-750, menoplace chamber, Ningho, China). The pressure inside the chamber was adjusted to 2.5 ATA and the oxygen concentration was higher than 95 %. The set pressure and oxygen concentration were maintained for 60 minutes. When the pressure within the chamber was decreased to 1 ATA, rots were taken out. The rats in one-HBOT group were given one HBO therapy immediately after resuscitation, and the rats in three-HBOT group were given one HBO therapy im-mediately after resuscitation with additional twice HBO therapy within 24 hours ((q 8 h). The one-way ANOVA and Pearson's bivariate methed were used for statistics. Results Twenty-four hours after resuscitation, the levels of lactate, induced nitric oxide synthase (iNOS), nitric oxide (NO), and tumor necrosis factor-α (TNF-α) in in-testinal tissue of rats in both HBOT groups were significantly lower than those in the rats of shock group without HBOT (P < 0.05). The histological injury grading scores of intestinal tissue in both HBOT group was significant lower than that in shock group (P < 0.05). There was positive correlation between the levels of iNOS and NO in intestinal tissue (P < 0.001). All the above-mentioned parameters in the three-HBOT group were better than those in one-HBOT group, but the difference was not significant (P > 0.05). Conclusions HBO decreases the production of inflammatory factors, inhibits the excessive inflammatory reaction to T/HS, and prevents the mucosal barrier of intestine from I/R injury after resuscitation from T/HS.

Objective To analyze the clinical characteristics of acute hematogenous pulmonary tuberculosis and tuberculous meningitis in pregnant women after in vitro fertilization and embryo transfer (IVF-ET).Methods Clinical data of 11 cases of hematogenous pulmonary tuberculosis and tuberculous meningitis in women after IVF-ET admitted in Hangzhou Red Cross Hospital from January 2003 to October 2012 were retrospectively analyzed.Results The clinical manifestations of acute hematogenous pulmonary tuberculosis and tuberculous meningitis were non-specific.All cases presented with fever,and some were accompanied by headache,but no typical respiratory manifestation was observed.Chest X-ray showed typical military lesions.Miscarriage occurred in 11 patients within 2 to 5 weeks after the onset of fever,including 3 received artificial abortion.Conclusions The outcome of hematogenous pulmonary tuberculosis in pregnant women after IVF-ET is less favorable.Physicians should be aware of tuberculosis in pregnant women after IVF-ET,especially for those with long-term fever and not responding to anti-inflammatory treatment.

Peripheral arterial disease(PAD)is a common manifestation of systemic atherosclerosis associated with significant morbidity and mortality.The goals of management for patients with PAD are to relieve exertional symptoms,improve walking capacity,improve quality of life,and prevent and retard the progression of systemic atherosclerosis.These patients should be candidates for aggressive secondary prevention strategies including tobacco cessation,physical activity,dietary modification,weight maintenance,blood pressure control,cholesterol control,antiplatelet therapy and angiotensin-converting enzyme inhibitor therapy.This article reviews the current non-intervention treatment of patients with PAD.

ObjectiveTo investigate the methods of treatment and effect in suppurative perichondritis of auricle.Methods27 cases with suppurative perichondritis of auricle were mentioned with sensitive antibiotic treatment in the whole and partly of the body.Carve and extradite the cases of abscess till entire debridement.ResultsAfter follow-up for 6 to 12 months,all 27 cases of auricles were preserved without feeling of causalgic.The efficient rate was 100％.Although 5 cases of auricle's shape were shrinked,the others preserved a good shape of auricle.The relief rate was 81.5％.ConclusionThe effective way of treating suppurative perichondritis of auricle was using sensitive antibiotic and entire debridement.

Objective:To provide chemical basis for processing of leech through investigating the variations of composition of leech scalded with talc powder. Methods: Amino acids were determined by HPLC post column derivatization and steroids by GC MS. Results: The results showed the total contents of amino acids in scalded leech were reduced and the steroids of it were changed. Conclusion: The processing method of leech used at the moment has a great influence in chemical components of leech.

Objective To observe the clinical efficacy of abdominal acupuncture in treating perimenopausal insomnia.Method Sixty patients with perimenopausal insomnia were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by abdominal acupuncture, while the control group was by regular body acupuncture. The FSH, LH, and E2 contents, and Pittsburgh Sleeping Quality Indext (PSQI) were observed before and after intervention, and the clinical efficacies were compared.Result The total effective rate was 90.0% in the treatment group versus 86.7% in the control group, and the difference was statistically insignificant (P>0.05). The PSQI score was changed significantly in both groups after intervention (P<0.01). After intervention, there was no significant difference in comparing PSQI score between the two groups (P>0.05). The FSH, LH, and E2 contents were significantly changed after intervention in both groups (P<0.01). After intervention, there were no significant differences in comparing FSH, LH, and E2 contents between the two groups (P>0.05).Conclusion Abdominal acupuncture in an effective method in treating perimenopausal insomnia.
