Reperfusion is the most effective treatment for acute myocardial infarction, markedly reducing mortality and morbidity. Reperfusion however induces necrotic and apoptotic damages to cardiomyocytes, that were viable prior to reperfusion, a process called myocardial ischemia/reperfusion injury(MI/RI). Over the past 30 years, hundreds of experimental interventions (both pharmacologic and nonpharmacologic) have been reported to protect the ischemic myocardium in experimental animals; however, with the exception of early reperfusion, none has been translated into clinical practice. The population-based survey assessed men have about twice the total incidence of morbidity and mortality of women, and the sex gap in morbidity tends to diminish after age 45 years. So hormone replacement therapy (HRT) is given to treat the MI/RI, and lots of studies shows that the side effect is greater for estrogen, compared with phyestrogen. In this article, we review the important pathogenesis of myocardial ischemia reperfusion injury, the prevention and limitations of HRT. And we highlight the mechanism of phyestrogens treatment the MI/RI in experiment. The aim is to provide the theoretically new way of develop the safe and effective products for the researchers.

Objective To study a possible correlation between the duration of reproductive period ( from puberty to menopause) and the prognosis of ischemic stroke. Methods Female in-patients with acute ischemic stroke confirmed by CT/MRI in the Neurology Department of the First Affiliated Hospital of Zhengzhou University from 09/03/2006 to 08/30/2008 were enrolled in this study. The probable risk factors of prognosis were analyzed and recovery was assessed by modified Rankin score (MRS) at 6 months followup. Multivariate Logistic regression was used for statistic analysis. Results 371 female patients were enrolled. The average age was (66. 2 ± 10. 0) years; average menopause age was (48. 5 ± 3.9 ) years and average duration of reproductive period was (33.3 ± 4. 3) years. There is a negative correlation between the duration and MRS (OR =0. 285, 95% CI: 0. 095-0. 850, P =0.024). There is no correlation between menopause age and prognosis of stroke. Conclusions Duration of reproductive period is a predictor for prognosis of ischemic stroke. Patients with longer reproductive period have better prognosis.

OBJECTIVETo compare the difference in the efficacy on low back pain of cold-damp pattern between electric-thermal Bian-stone therapy and moxibustion box therapy.

METHODSForty-one cases of low back pain of cold-damp pattern were randomized into an electric-thermal Bian-stone therapy group (group A, 26 cases) and a box moxibustion therapy group (group B, 15 cases). In the group A, the electric-thermal Bian-stone was placed over Shenshu (BL 23) and Weizhong (BL 40). The temperature of stone was adjusted in accordance with patient's comfort. In the group B, moxibustion box was used over Shenshu (BL 23) and Weizhong (BL 40). The treatment was given once every day or every two days. Ten treatments made one session. The symptom and physical signs score of low back pain and the score of cold-damp syndrome were observed before and after treatment in the patients.

RESULTSThe symptom and physical signs score of low back pain and the score of cold-damp syndrome were all improved in the two groups (all P < 0.01). The changing rate of symptom and physical signs and syndrome were (37.04 +/- 32.68)% and (22.85 +/- 29.95)% in the group A, and were (47.29 +/- 22.08)% and (23.89 +/- 22.53)% in the group B, respectively, without significant difference in comparison between the two groups (all P > 0.05).

CONCLUSIONThe efficacy on low back pain of cold-damp pattern treated with the electric-thermal Bian-stone therapy is similar to that of moxibustion box therapy. This therapy is characterized as more convenient, safer operation and less pollution.

Objective To investigate the clinical feature,diagnosis,treatment and prognosis of endometriosis of the bladder.Methods A retrospective study was conducted to review the clinical data of 10 patients with bladder endometriosis.Patient's age ranged from 30 to 48 years (with mean age of 38 years).Eight cases were admitted to hospital with urinary tract irritating symptoms during the menstrual period and 6 cases with hematuria; 2 patients without any symptoms were found through examination.The course of disease was 1-36 months (with mean of18 months).Ultrasound shows with low echo,single,wide base and no significant blood flow mass whose boundaries are less clear within the bladder wall.CT reveals soft-mass protruding into the bladder.Results Eight of the 10 patients were undergone partial cystectomy.And 2 cases was treated with transurethral resection.All cases were pathologically confirmed to be bladder endometriosis.Recurrence and ectopic lesion had not be found during follow-up period from 10 to 72 months (with mean of 30 ± 5.6 mon).Conclusions Endometriosis is a common disease in females in their reproductive years,but thebladder endometriosis is rare.The initial diagnosis needs to be made combining with imaging studies.It is confirmed by cystoscopy and pathological biopsy.Surgery is the option for the treatment of bladder endometriosis.

Objective To investigate the fuction of tumor necrosis factor alpha(TNF-?),interleukin-1 beta(IL-1?) and interleukin-6(IL-6) in children with intracranial infection.Methods TNF-?,IL-1? and IL-6 levels of serum and cerebrospinal fluid(CSF) were determined in the purulent meningitis group(25 cases),tuberculous meningitis group(17 cases),viral meningitis group(30 cases)and control group(20 cases)by enzyme-linked immunosorbent assay(ELISA).Results The levels of TNF-?,IL-1? and IL-6 obviously increased in CSF compared with that in the serum (Pa

Objective To explore the interaction between serum melatonin and the status of disease and probe the effect factor of serum melatonin change in asthmatic children.Methods Serum melatonin was measured in asthmatic children with 15 cases of mild persistent asthma,15 cases of moderate persistent asthma,15 cases of severe persistent asthma,15 cases of stable asthma and 15 cases of normal subjects by enzyme-linked immunosorbent assay(ELISA).Results The levels of serum melatonin in the 5 groups of mild persistent asthma,moderate presistent asthma,Severe Persistent asthma,Stable asthma,control subject were(22.76?5.16)ng/L,(16.79?3.35)ng/L,(11.54?1.45)ng/L,(22.06?3.36)ng/L,(28.72?4.32)ng/L,respectively.There were significant differences between any of them(Pa

Objective To evaluate the relationship between Multi-slices spiral(MSCT) perfusion and microvessel density (MVD) in maxillofacial tumors. Methods Thirty-one cases of maxillofacial tumors were studied with MSCT perfusion imaging before operation. The time-density curve, perfusion, time to peak(TTP), and Peak enhancement imaging (PEI) of tumors were calculated. MVD of the tumors was measured with immuno-histochemical method by means of detecting factor Ⅷ in all the histologic specimens. Relativity analysis was carried between MSCT perfusion imaging parameters, perfusion curve types and MVD. Results MVD of maxillofacial tumors were higher than normal tissue. MVD remarkably correlated with malignancy of the tumors. Perfusion and time to peak (TTP) correlated well with MVD(t=7.09,4.10, P0.05). Significant difference of MVD in three types of perfusion curve was found(F=8.09,P

OBJECTIVETo investigate the causes of chronic cough in children.

METHODSA prospective cohort study was performed on 111 children with chronic cough who were referred to the First Affiliated Hospital of Guangxi Medical University between December 2008 and January 2011. The causes of chronic cough were investigted.

RESULTSCough variant asthma (45 cases, 40.5%) was the most common cause of chronic cough, followed by upper airway cough syndrome (34 cases, 30.6%), postinfectious cough (19 cases, 17.1%), allergic cough (5 cases, 4.5%), Tourette's syndrome (4 cases, 3.6%), psychogenic cough (1 case, 0.9%) and endobronchial tuberculosis (1 case, 0.9%). The causes were not identified in 2 cases (1.8%). A single cause for chronic cough was noted in 60 patients (54.1%), and multiple potential causes were noted in 49 patients (44.1%), including two coexisting causes in 47 patients (42.3%) and three in 2 patients (1.8%).

CONCLUSIONSThe top three causes of chronic cough in children are cough variant asthma, upper airway cough syndrome and postinfectious cough.

COPI is a protein complex that transports vesicles from the Golgi complex back to endoplasmic reticulum. Many viruses such as RNA viruses, DNA viruses and retroviruses, hijack or adapt COPI related proteins including coatomer, ARF1 and GBF1 for their own benefits. Here, we summarize the current progress of the roles of COPI related proteins in virus replication.
