OBJECTIVE To realize the situation of the infection of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) and the drug resistance among the female patients with urogenital tract infection.METHODS Totally 813 specimens in the female patients with urogenital tract infection were collected,cultured and tested for drug sensitivity with mycoplasma test drug sensitivity kit.RESULTS From the specimens of 813 cases the infection of Uu was in 296 cases(36.4%),the infection of Mh in 13 cases(1.6%),and the mixed was in 71(8.7%) cases,totally 380 cases(46.7%) were infected.The results of drug sensitivity showed that the sensitivities of Uu and Mh to josamycin,doxycycline and minocyclin were remarkable and the drug resistance of Uu and Mh to ofloxacin was the most prominent.CONCLUSIONS The infection of Uu and Mh is high among the femalepatients with urogenital tract infection.Especially the infection of Uu is usual.Uu and Mh have high drug resistance to many antibiotics,especially to ofloxacin.There is some difference between the drug resistances of Uu,Mh and Uu+Mh.To treat the infection of Mycoplasma some antibiotics are good choices,such as josamycin,doxycycline and minocyclin.

Liver fibrosis can be caused by chronic liver injury arising from various etiological factors.The activation of the hepatic stellate cell(HSC) is the central event in liver fibrosis,the apoptosis of which was the initiating factor for the reversal process.The apoptosis of HSC is very complicated.The signaling pathways lack of enough research in regulating and controlling and activating HSC's apoptosis.The apoptosis pathways as known currently mainly include mitochondrial pathway,death receptor pathway and non-death receptor pathway.Based on these signaling pathways,selectively inducing cell death of activated HSCs is becoming the new antifibrotic treatment.This review focuses on the new progress of HSC's apoptosis signaling pathways,and summarizes the drugs that have the effect of inducing HSC apoptosis.

Objective To evaluate the rate and types of human papillomavirus (HPV) in vulvar intraepithelial neoplasia (VIN).Methods We detected HPV DNA in 67 lesion tissues collected from 40 VIN patients with PCR based reverse line blot hybridization and DNA sequencing. The PCR using GP5/GP6 primers in HPV L1 region resulted in a 150-bp fragment. When the PCR did not amplify the target DNA,another PCR using SPF1/SPF2 primers was performed to amplify the 65-bp fragment.Results HPV DNA amplified with primers GP5/GP6 was positive in 52.2% (35/67) of the lesions. Of the 32 negative lesions,26 (81.2%) were positive for HPV DNA amplified with SPF1/SPF2 primers. The total positive rate was 91.0% (61/67). Ninety percent of the HPV belonged to high risk types. Sequencing data showed that the genotypes of 31 mono-infection lesions were the same as those of the reverse line blot results,yet the sequences in 4 multi-infection samples could not be determined. Of the 26 SPF PCR products,24 could be sequenced. 80.6% (25/31) patients with multiple lesions displayed the same genotype,suggesting HPV in the different lesions from the same patient was monoclonal.Conclusion The high risk type of HPV is associated with vulvar intraepithelial neoplasia and may play an important role in the development of invasive vulvar carcinoma.

Objective　The authors present a retrospective analysis of 22 patients with primary central nervous system lymphoma(PCNSL) in order to provide a reasonable basis for the diagnosis and treatment of the disease. Methods　This report involves a clinicopathological study of 22 patients with histologically proven PCNSL,all diagnosed between January 1993 and May 2000. Univariate and multivariate regression analysis are used to determine prognostic factors significantly associated with an unfavorable or favorable impact on survival. Results　The cohort included 11 men and 11 women whose median age at diagnosis was 49.5 years. At the end point of follow-up, 11 died. The median survival time for the patients in study was 14.5 months. With univariate and multivariate regression analysis, prognostic factors significantly associated with survival included intrathecal injection(P=0.005) and local/diffuse neurological deficit(P=0.031). Conclusion　There continues to be a significantly increasing incidence of PCNSL. This survey throws light on the clinical and prognostic features of this uncommon disease. Through univariate and multivariate regression analysis the authors highly recommend a theraputic regime including surgery, intrathecal injection and chemotherapy, especially those drugs capable of passing blood-brain barrier, for example high dose MTX.

The effects of cyclooxygenase 2 (COX 2) on alcohol induced liver injury in rats were investigated. Rats were randomly divided into three groups: Control group was given with corn oil plus dextrose; Model group with corn oil plus ethanol; Treatment group with corn oil plus ethanol and a selective COX 2 inhibitor celecoxib. All materials were injected into stomach through intragastric tubes. Liver samples were analyzed with histopathology, fatty staining and immunohistochemistry. Glutathione s transferase (GST) activity of liver tissue and plasma were detected. Levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in serum were measured. Compared with the control group, positive fatty staining cells and expression of COX 2 in liver, level of ALT and AST in serum and activity of GST in plasma were all significantly increased in the model group, but the GST activity in liver was decreased. However, these changes were all reversed in the treatment group. The results show that the model of alcohol induced liver injury in rats has been set up successfully, the selective COX 2 inhibitor celecoxib can protect against alcohol induced liver injury in rats and COX 2 may play a role in alcohol induced liver injury

Objective To observe different effects of cyclic and continuous nutrition infusion on serum nutritional indicators, peripheral white blood cell counts (WBC), arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2) and acute physiology and chronic health evaluation Ⅲ (APACHE Ⅲ ) score in patients with mechanical ventilated respiratory failure (MVRF).Methods A cross-over and self-controlled trial was conducted in 48 patients with MVRF treated in a medical intensive care unit during December 2006 to June 2009, and continuous nutrition (group A) and cyclic nutrition (group B) were infused respectively for patients of the two groups.Serum levels of albumin (ALB), pre-albumin (PA), transferrin (TR), PaO2, PaCO2, WBC and APACHE Ⅲ score were measured for the patients with 24-hour continuous nutrition (group A) and 16-hour cyclic nutrition (group B)infusion.Effects of the two nutritional therapies were compared.Results After nutrition infusion, serum levels of ALB, PA and TR were (34±3)g/L, (196±28)mg/L and (2.1±0.3 ) g/L in group A, and (35 ±4) g/L, (198 ±25) mg/L and (2.0 ±0.4) g/L in group B, respectively; and PaO2 and PaCO2levels were (92 ± 12) mm Hg ( 1 mm Hg =0.133 kPa) and (42 ± 10) mm Hg in group A, and (91 ±9)mm Hg and (42 ± 10) mm Hg in group B, respectively.WBC and APACHE Ⅲ score were ( 11.8 ± 1.7) ×109/L and 38 ±7 in group A, and ( 12.6 ± 1.2) × 109/L and 40 ±6 in group B, respectively.Significant difference in serum levels of PA and TR was found between the two groups (PPA =0.019 and PTR =0.013),while there was no significant difference in other indictors between the two groups.Conclusions 24-hour continuous nutrition infusion for patients with MVRF can obviously improve their serum levels of PA and TR,but has no effect on serum level of ALB, PaO2, WBC and APACHE Ⅲ score in critical ill patients, as compared to those with 16-hour cyclic nutrition infusion.

OBJECTIVETo explore the effect of Qingfei Huoxue Recipe (QHR) combined azithromycin in treatment of intractable pediatric mycoplasma pneumonia.

METHODSTotally 124 intractable pediatric mycoplasma pneumonia patients at our hospital were recruited in this study, and randomly assigned to the treatment group and the control group, 62 in each group. Patients in the control group took azithromycin, while those in the treatment group additionally took QHR. All patients received omnibearing systematic nursing. Therapeutic efficacy, clinical indices (such as disappearance time of cough and rales, recovery time of body temperature) , and the incidence of adverse reactions were observed.

RESULTSAfter treatment the total effective rate was 91.94% (57/62 cases) in the treatment group and 77. 42% (48/62 cases) in the control group with statistical difference (P < 0.05). Compared with the control group, disappearance time of cough and rales, recovery time of body temperature were obviously shortened in the treatment group with statistical difference (P < 0.01). There was statistical difference in the incidence of adverse reactions between the two groups [3.23% (2/62 cases) vs 38.71% (24/62 cases) , P < 0.01].

CONCLUSIONIn clinical treatment for intractable pediatric mycoplasma pneumonia, Chinese medicine combined Western medicine plus scientific and systematic nursing showed more obvious advantages with significant efficacy, which was worth spreading.
