Objectives:To investigate the prevalence situation and antibiotic resistance of chlamydia trachomatis (CT),ureaplasma urealyticum(UU) and mycoplasma hominis(MH) in infertile female patient,and to analyze the resistant of mycoplasma to common antibiotics. Methods:The cervical secretion samples from 2186 female infertility and 210 pregnancies women were collected. Then chlamydia trachomatis antigen was detected by immunoassay. Mycoplasma (UU and MH) were isolated and tested antimicrobial susceptibility for 12 kinds of antimicrobial drugs. Results:In the trial group 173 were CT-positive at a rate of 7.9%,and 1102 were positive for the mycoplasmae at a rate of 50.4%,of which 987 were UU infections and 115 were MH infections.The number of CT,UU and MH infections totaled 1275 cases,leading to an overall infection rate of 58.3%. The top three antibiotics for drug sensitivity in the UU,MH and UU+MH cultures were josamycin,minocycline and clarithromycin.The three antibiotics,to which the pathogens were most tolerant,included ofloxacin,norofloxacin and sparfloxacin. Conclusion:The infection rate of chlamydia and mycoplasma in infertility women is obviously higher than normal pregnanted,this shows the fact that chlamydia and mycoplasma infection of genitourinary tract may be one reason of infertility.The sensitivity of mycoplasma to common antibiotics especially to quinolones and macrolides has decreased.

Chronic lung disease is a very common complication caused by inhaled hyperoxia, mechanical ventilation and pulmonary infection in preterm infants. It shows early inflammation and late alveoli fusion with mesenchymal fibroblast proliferation. Mitogen activated protein kinase is a very important signal transduction pathway in eukaryotic cells.It plays an important role in the cell inflammation, proliferation, differentiation, survival and apoptosis, which may contributes to the chronic lung disease.

OBJECTIVE: To summarize the cause and mechanic of inflammation reaction induced by medical biomaterials in the body.DATA SOURCE: A computer-based online search of Pubmed database was undertaken to identify the relevant articles published from January 2004 to December 2008 in English with the key words of "biomaterials, inflammation, mechanism".Meanwhile, with Chinese articles were retrieved from CNKI database between January 2005 and December 2008 with the key words of "biomaterials, inflammation, mechanism".DATA SELECTION: Articles concerning the cause and mechanic of inflammation reaction induced by medical biomaterials were included. Articles addressing physical and chemical features and mechanics of medical biomaterials were excluded.MAIN OUTCOME MEASREUS:①After the material implants in vivo, inflammatory cell and material adhering.②Cell factor expression.RESULTS: After initially examined 70 literatures were obtained. According to inclusion and exclusion criteria, the reasons and the mechanism related to the medical biological material in host in vivo for causing the inflammation were analyzed. Along with the tissue engineering development, various new high-polymer medicine biological materials with good biological compatibility,the biological activity and the biodegradation absorption function are emerging unceasingly. The biomedicine material was used to repair or substitute damage organization and the organ, and to cause function recovery. The infection was still the serious complication following the medical biological material was implanted. The mechanism of biomedicine material-induced infection is: complement in blood adhere the biological material surface, which causes collection and adherence of integrin-mediated leukocytes, release of cytokines and growth factors from adherent monocytes/macrophages, resulting in the occurrence of biomedicine material-related infection. To prevent the medical biological material-related inflammation, we should first embark from the material itself, and seek for some to respond the small medical material to the host inflammation.CONCLUSION: The success of material implantation depends on the medical biological material relevant inflammation. The production of biomaterial-related inflammation is action results of inflammatory cell, inflammation factor, complement as well as enzyme, oxygen free radical. Material surface microstructure, chemistry and dielectric and so on immediately influence inflammatory cells on material response.

This study was to evaluate the risk factors of nocturnal hypoglycemia in elderly patients with type 2 diabetes by continuous glucose monitoring system. Fifty-one type 2 diabetic patients aged 60 or above were enrolled and the episodes of nocturnal hypoglycemia were documented. The risk factors of nocturnal hypoglycemia were analyzed by logistic regression and the cut-off of glucose levels at bedtime for nocturnal hypoglycemia was evaluated. There were twenty-two patients with total 681 nocturnal hypoglycemic episodes. Logistic regression analysis showed that the lowest glucose level at bedtime was the risk factor of nocturnal hypoglycemia (OR=0.36, 95% CI:0.13-1.00, P<0.05), while the gender, age, diabetes duration, therapy regimen, the highest and average glucose levels at bedtime were not associated to nocturnal hypoglycemia. Receiver operating characteristic curve (ROC) showed that the bedtime glucose at≤6.2 mmol/L was the best cut-off point for predicting nocturnal hypoglycemia.

It was pointed out that the development of theory of TCM was restricted by the indistinct concepts.The advantages and disadvantages of the concept between traditional Chinese medicine and western medicine were analyzed.Basing on literature researches and modern science researches can solve the concept problems of the theory of TCM.

This paper,introduced the manufacture process and quality control method of Xiao- erqingfei Suppository.The suppository tallied with requirements of China Pharmacopeia (the 85th edition).Its main active components were identified with TLC.Two represen- tative components were determined:ephedrine and glycyrrhizic acid.

Objective To investigate the effect of anti-snoring pillow for the treatment of obstructive sleep apnea in patients with heart failure.Methods Forty seven HF patients with OSAHS and 12 HF patients with simple snoring were enrolled.All the patients were divided into 3 groups:control group (n =12),mild-moderate OSAHS group (n =26) and severe OSAHS group (n =21).All the patients received the treatment of anti-snoring pillow and their sleep apnea parameters were evaluated by PSG at the same time.Results The sleep apnea parameters including AHI,OAI,ODI,mean SpO2％ and snore index were significantly improved in severe and mild moderate OSAHS group with anti-snoring pillow.Conclusion Anti-snoring pillow can reduce snoring index in all OSAHS patients and simple snorers.Sleep apnea and hypoxemia were greatly improved in mild-moderate OSAHS-HF patient while the anti-snoring pillow is not perfect in severe OSAHS patients with HF to replace PAP.

Objective To evaluate MRI diagnostic accuracy and clinical value on the pancreatic carcinoma.Methods 79 patients with suspected pancreatic carcinoma were imaged by T1-weighted spin-echo pulse sequences and T2-weighted fast spin-echo pulse sequences in axial,sagittal and coronal planes with a pelvic phased-array coils.Results 43 patients were diagnosed as pancreatic carcinoma using MR imaging,in which 39 patients were proved pathologically by biopsy.Conclusion MRI is effective diagnostic modality in localizing and staging pancreatic carcinoma and guiding for the choice of pancreatic carcinoma treatment.

Objective:To search the effects and possible mechanisms of Lianggesan on the acute lung injury(ALI) rat induced by endotoxin. Methods: Endotoxemia was induced by intravenous lipopolysaccharide (LPS,5 mg/kg), then treated with Lianggesan. The levels of TNF-?, IL-1?and IL-10 in serum and wet-to-dry weight ratio of lung were detected. Results:In LPS group the levels of TNF-? began to increase at 1h, which reached the peaks at 2h(P
