Objective To observe the efficacy of Foley balloon combining with uterine adhesions to prevent the recurrence of intrauterine adhesions after resection of intrauterine adhesions.Methods Patients underwent resection of intrauterine adhesions were randomized into two groups. 30 patients in control group underwent the therapy of uterine adhesions to prevent the relapse intrauterine. On the other hand, the study group with 30 patients were placed Foley balloon for 5 ~ 7 days and combined with the therapy of uterine adhesions to intervention for 1 ~ 2 weeks. All patients were followed-up for 1 ~ 2 months, and the result of the intrauterine adhesion were assessed by hysteroscopy.Results The rate of the relapse in control group was 3.33%; the study group had the same result (the rate was 3.33%). There was no difference between these two groups.Conclusions The rate of recurrent intrauterine adhesions is no different between the control group of only use therapy of uterine adhesions and replacement of Foley balloon combining with therapy of uterine adhesions as intervention.

Objective To study the effects of aged and exercise training on hydroxylysylpyridinoline (HP) crosslinking concentrations of extracellular matrix in right ventricular (RV),left ventricular septum (LVS) and left ventricular free-wall (LVFW) in Fischer 344 rats.Methods We evaluated HP crosslinking concentrations of RV,LVS and LVFW extracellular matrix in young adult versus old Fischer 344 rats using high-pressure liquid chromatography (HPLC).Rats were assigned to either a sedentary control group or an exercise training group.Results HP crosslinking concentrations in LVS [(0.23±0.01) vs.(0.43±0.03)mol HP/mol Col,P＜0.05] and LVFW [(0.22±0.05) vs.(0.51±0.03) mol HP/mol Col,P＜0.05] in old sedentary control rats were elevated compared with adult sedentary rats.In adult exercise training rats,training had no effect on HP crosslinking concentration in any of the three regions of the heart.As compared with old sedentary rats,HP crosslinking concentrations in LVS [(0.22±0.06) mol HP/mol Col vs.(0.43±0.03)mol HP/mol Col,P＜0.05] and LVFW[(0.21±0.07)mol HP/mol Col vs.(0.51±0.03) mol HP/mol Col,P＜0.05] were decreased in old exercise training rats.Conclusions HP crosslinking concentration are increased with aging in LVS and LVFW of rats,and exercise can prevente this age associated change.

Objective To study the relationship of left-ventricular function change with circulation levels of CD34+ cells,toll like receptor 2 (TLR2),TLR4 and high sensitivity C-reactive protein (hs-CRP)in elderly isolated systolic hypertension.Methods According to New York Heart Association (NYHA)class,left ventricular ejection fraction (LVEF) and systolic blood pressure (SBP),the healthy subjects and the patients were divided into 5 groups:control 30 cases,class Ⅰ 25 cases,class Ⅱ 29 cases,class Ⅲ 24 cases and class Ⅳ 20 cases.The expressions of circulating CD34 + cells,TLR2 and TLR4 in the patients and healthy subjects were measured by flow cytometry.The level of hs CRP was measured by nephelometry immunoassay.Results In class Ⅳ versus class Ⅰ,the levels of LVEF[(26.4±2.1)％vs.(40.5±3.6)％]and CD346 [(0.5±0.2) × 109 vs.(2.5±0.4) ×109 /L]were decreased,while SBP[(211.1±8.4)mm Hg vs.(151.1±5.9)mm Hg],TLR2 [(8.0±1.0) vs.(3.2±1.1)MFI],TLR4 [(6.4±1.3)MFT vs.(2.4±1.1)MFI]and hs-CRP [(14.7±0.3)mg/L vs.(4.9±0.6)mg/L]were increased (all P＜0.05).Conclusions The lower levels of CD34+ cells,higher TLR2,TLR4 and hs CRP levels are correlated with increasing SBP,decreasing LVEF and higher NYHA class.

Objective To study the reproductive outcome of infertile women suffered from hydrosalpinx treated by laparoscopic salpingostomy or salpingectomy.Methods There were 77 infertile women diagnosed hydrosalpinx by HSG or B ultrasonography and excepted for other infertile factors. Unilateral or bilateral salpingostomy or salpingectomy was performed after hydrosalpinx conifrmed by laparoscopy. Seventy seven patients were followed up for 1 ~ 4 years postoperatively.Results Among 77 cases 39 cases (50.65%) got pregnancy. Thirteen cases (16.88%) conceived spontaneously and 26 cases (33.77%) conceived by IVF-ETin. Thirty ifve cases delivered health babies and 3 cases of pregnancy, 1 cases of early abortion.Conclusion Both laparoscopic surgeries were effective treatment of hydrosalpinx results in infertility. After operation the pregnant rate of those conceived by IVF-ET is higher than spontaneously.

Objective To describe the disease's spectrum of fever patients,especially to analyze the epidemic characterization of infectious diseases,to offer the proof for fever department in screening of infectious diseases.Methods A total of 15081 patients were analyed for patients presenting to the Infectious Diseases Department,People's Hospital,Peking University,between June 2005 to May 2006.A retrospective study was used to analyze the disease's spectrum and epidemic characterization.Results Among the disease's spectrum of fever patients,the first leading cause was respiratory diseases(78.22%),followed by infection with the special patients(10.50%)、acute gastroenteritis(3.57%)、the infection at other site with etiological factor determined(2.82%)、infectious diseases(2.30%)、urinary system infection(2.06%) and fever of unknown origin(0.53%),respectively;Among the spectrum of infectious diseases,the first leading cause was infectious diarrheal disease(29.97%),followed by measles(24.78%)、lung tuberculosis(11.24%).Conclusion The spectrum of fever is complex.To obtain the epidemic characterization of infectious diseases,it's helpful to the fever department to screen and prevent the infectious diseases.

Objective To explore the aesthetic effect of the applying the expanded skin flap to re-pair facial defects produced by removal of nevus, hemangioma, scars and so on. Methods The experience of the treating 67 patients with facial lesions using the expanded flaps were reviewed. The proper expand-ers were chosen according to the scope of the facial lesion. The incision was located at the scar region and the dissection was executed in the superficial layer of the SMAS. The interspace was larger than the ex-pander by 1.0～1.5 cm. After exact hemostasis, the expanders and negative pressure drainage tubes were placed into the interspace. The design of the facial expanded skin flap included the advance, rotation, and transposition of skin flap and so on. The advance of skin flap took fully use of the expanded skin flap without the donor site defect. The transposition of skin flap also took fully use of the expanded skin flap, furthermore, it overcame the displacement and the disfiguration caused by the applying of the advance skin flap and rotation skin flap. The incisions in face were designed to a minimal extent and parallel to the Lan-ger line. Results All of the 67 cases got aesthetic satisfied results with all the flaps surviving. Conclusion The application of expanded skin flaps is proved to be an effective way of repairing facial wound when there is enough normal facial skin for expansion.

Objective To study the effect of overexpression of tumor necrosis factor-α (TNFα) in failing heart on contractile function of mouse diaphragm. Methods Diaphragms excised from transgenic mice with cardiac specific overexpression of TNF-α and from wild-type littermate controls were studied in vitro with direct electrical stimulation. Cytosolic oxidant levels were measured with 2',7'-dichlorofluorescin diacetate (DCFH-DA). Emissions of the oxidized product were detected by fluorescence microscopy. Results The diaphragm contractile force in transgenic animals with heart failure was 47% less than in controls [(13. 2±0. 8) N/cm2 vs. (25.1±0. 6) N/cm2 , P＜O. 01]. The weakness was associated with greater intracellular oxidant levels (P＜0. 05) and was partially reversed by 30-minute incubation with the antioxidant N-acetylcysteine (NAC) 10 mmol/L ( P ＜ 0. 01 ).Exogenous TNF-a 500 mmol/L increased oxidant production in diaphragm of wild-type mice and caused weakness that was inhibited by NAC. Conclusions Overexpression of TNF in failing heart causes oxidative stress which leads contractile dysfunction in mouse diaphragm.

Objective To identify the pathogen of an influenza epidemic situation and analyze the genetic characteristic of hemagglutinin( HA ) gene and neuraminidase(NA) gene of this pathogen. Methods Real-time RT-PCR was used to dectect nucleic acid of the pandemic( H1N1 ) 2009 virus from oropharyngeal swabs of initial influenza-like illness in epidemic. The viruses were was inoculated and isolated with embryonated eggs. And the HA gene and NA gene were sequenced to analyze their characteristic. Results The influenza epidemic situation was caused by the pandemic( H1N1 ) 2009 virus. The HA and NA sequences data showed that the virus had the high homology with reference virus, and the NA sequences had not the H274Y mutation. Conclusion In this study, the pandemic( H1N1 ) 2009 virus were similar with the vaccine-like virus and the isolated virus of China, and sensitive to oseltamivir.
