We investigated the distribution of Chlamydia trachomatis genotypes in the outpatients visiting STD clinics in Fuzhou City ,China .Between 2013 and 2014 ,a total of 2 019 urethral or endocervical specimens from susceptible genital C .trachomatis infections were collected and detected by using real‐time PCR assay kit .The C .trachomatis‐positive specimens were subsequently amplified with nested PCR for Omp1 region and analyzed by sequencing .Genotyping was performed by BLAST similarity search and phylogenetic tree analysis .Eighty‐three of the 86 C . trachomatis‐positive specimens were suc‐cessfully sequenced .Only one specimen was identified as multiple infection .Eight different genotypes were identified .The most prevalent was F (36 .59% ) ,followed by E (24 .39% ) ,D (12 .20% ) ,G (9 .76% ) ,J (9 .76% ) ,H (3 .66% ) ,K (2 .44% ) and B (1 .22% ) .Synonymous mutation rate and non‐synonymous mutation rate among Omp1 genes of different geno‐types were calculated .All genotypes but G showed dN/dS values of<1 .Genotypes F and E were commonest .Synonymous sub‐stitution was the major pattern of variation in the process of Omp 1 gene evolution .

Objective To conduct a retrospective analysis of the relationship between the time of rehabilitation intervention and its effectiveness among hemiplegic patients after cerebral infarction.Methods Fifty-four hemiplegic stroke patients within 1 week of onset were randomly divided into three equal groups of 18:In the A group rehabilitation was begun 1 to 2 weeks after onset; in the B group it was started between 2 and 4 weeks; in the C group rehabilitation was begun after four weeks.The patients all received comprehensive hemiplegic limb training,electric standing bed training,functional electrical stimulation and medical gymnastics for hemiplegia.Motor function was assessed using the Fugl-Meyer balance function assessment and the modified Barthel index before treatment,in the course of the first week of treatment and 3 months later.Results A group and B group made similar progress,but the curative effect in group C was significantly weaker.Conclusion Rehabilitation should be started within 1 month after the onset of cerebral infarction.

OBJECTIVE:To analyze the relative factors of ADR in our hospital.METHODS:A total of 185 ADR case reports collected in 2006 were analyzed statistically.RESULTS:Of the total 185 cases,33(17.8%) were reported by physicians,12(6.5%) were new and severe ADR,62.7% were reports from pharmacy department,infusion room and department of derma-tology.For a few departments,the ADR case reports were zero.121(65.4%) were caused by anti-infective drugs;138(74.60%) were caused by intravenous drip and 108(58.4%) manifested as lesions of skin and its appendages.CONCLUSION:The incidence of ADR is related to multi-factors;however,rational use of drugs is the key conducive to the reduction of ADR incidence.

Objective To observe the influence of telephone follow-up and home follow-up on compliance behavior and activities of daily living (ADL) of stroke patients during rehabilitation. Methods 50 cases were as telephone follow-up group and 50 cases were as home follow-up group extracted from 355 stroke patients who discharged the hospital during August 1, 2010 to July 1, 2012. They were followed up 2 weeks, 1 month and 3 months after discharge respectively. Their ADL were assessed with Bathel index (BI) at discharge and 3 months after discharge, and the compliance behavior were assessed 3 months after discharge. Results There was no significant difference in the score of BI between 2 groups at discharge (P>0.05), and the score of BI improved in both groups 3 months after discharge (P<0.05), but it was higher in the home follow-up group than in the telephone follow-up group (P<0.05), as well as the rate of compliance behavior (P<0.01). Conclusion Regular home follow-up can improve the compliance behavior of stroke patients during rehabilitation.

Objective To investigate the related factors of phlebitis caused by PICC and support effective preventive nursing measures. Methods 163 patients diagnosed as malignant tumor who first used peripherally inserted central catheters (PICC) were recruited. Patients were observed for 3 months. According to the diagnostic criterion of infection, 34 patients with phlebitis were divided into the phlebitis group and others were divided into the control group. All patients were investigated for general information survey :sex, age, tumor type, allergic history,location of inserted vein, one-time success rate,activity after catheter, elbow bending,phlebitis occurred time, grade and type. Laboratory markers:WBC,neutrophils,immune parameters, fasting plasma glucose. Trait anxiety inventory (T-AI)was used for assessment of emotional state. Case-control study between groups was carried out. Results The results of univariate analysis showed that location of inserted vein,times of inserting vein,activity of inserted limb,elbow bending,blood sugar level and emotion were associated with phlebitis. Sex, age, tumor type, allergic history, immune function,WBC,neutrophils were not involved with phlebitis. The results of multivariate logistic regression analysis showed that PICC through basilica vein was the protective factor. Multiple insertions, more activity of inserted limb,durative anxious emotion were the risk factors of phlebitis. Conclusions Different location of vein,times of inserting vein,activity of inserted limb,elbow bending,high blood glucose level and persistent anxious emotion are the risk factors of phlebitis. Taking effective preventive measures before,during, and after PICC can reduce the incidence of phlebitis.

Objective To investigate the effects of autoantibodies (β1-AA) against second extra-cellular loop of the β1-adrenergic receptor (β1-AR-ECⅡ) in sera of patients with dilated cardiomyopathy (DCM) on proliferation of rat CD4+T lymphocytes.Methods β1-AA in the sera of patients with DCM was purified by affinity chromatography .CD4+T lymphocytes were isolated by immunomagnetic microbeads from peripheral blood mononuclear cells of rats and its positive rate was detected by flow cytometry .CCK-8 meth-od was used to detect the proliferation of CD 4+T lymphocytes and flow cytometry was performed to measure the ratio of CD4+/CD8+T lymphocyte .Results The purity of isolated rat CD 4+T lymphocytes by immu-nomagnetic microbeads reached 97.7%.The proliferation of CD4+T lymphocytes stimulated by CD3/CD28 was inhibited by β1-AA in a concentration-dependent manner .However , IgG antibodies extracted from sera of healthy controls did not suppress lymphocyte proliferation (P>0.05).The suppression effect of β1-AA was inhibited after binding to antigenic peptides corresponding to β1-AR-ECⅡ and was completely blocked by metoprolol, a specific antagonist of β1-adrenergic receptor (β1-AR).In addition,β1-AA had no effects on the ratio of CD4+/CD8+T lymphocyte .Conclusion β1-AA isolated from DCM patients suppresses the pro-liferation of CD4+T lymphocytes through β1-AR pathway , which indicates that β1-AA can directly reduce the number of T lymphocytes and impair the function of T lymphocytes , resulting in immune system disorders and the development of DCM .

Objective To evaluate the risk factors for healthcare-associated infection(HAI)in senile dementia pa-tients,so as to adopt effective nursing measures to reduce the incidence of HAI.Methods Clinical data of 82 senile dementia patients aged≥60 years and hospitalized between January 2011 and June 2013 were analyzed retrospective-ly.Results Of 82 patients,28 (34.15%)developed HAI.The main infection site was lower respiratory tract(n=15,53.57%),followed by urinary tract(n=6,21 .43%).Univariate analysis revealed that risk factors for HAI in senile dementia patients were bedridden,long length of hospital stay ,dysphagia,indwelling urinary catheter,irra-tional use of antimicrobial agents,combined with tumor,and hypoproteinemia (all P <0.05 ).The main isolated bacteria were gram-negative bacilli(n=40,62.50%),the top three pathogens were Klebsiella pneumoniae (n=12, 18.75%),Escherichia coli (n =10,15.63%),and Pseudomonas aeruginosa (n =8,12.50%).Conclusion Reali-zing the risk factors and common pathogens of HAI in senile dementia patients is helpful for taking effective meas-ures to prevent and control the incidence of HAI .

Objective To investigate the effects of metformin on cell proliferation in differentiation degree of endometrial carcinoma cells and related mechanisms. Methods The endometrial cancer cell lines Ishikawa and AN3CA were used. Cell proliferation was assessed after exposure to metformin with or without epithelial growth factor receptor (EGFR) inhibitor AG1478 by cell counting kit-8 (CCK-8) method. EGFR mRNA was determined by reverse transcription (RT)-PCR. The expression of phosphorylation EGFR (p-EGFR) and total EGFR (t-EGFR) and phosphorylation extracellular signal-regulated kinase 1/2 (p-ERK1/2) and total ERK1/2 (t-ERK1/2) were examined by western blot. Results (1)CCK-8 experiment showed that metformin could inhibit the proliferation of endometrial cancer cells in a time-dependent manner and a dose-dependent manner (P<0.05), but the inhibition of well differentiated cell line Ishikawa was lower than that in poorly differentiated cells AN3CA (P<0.05). AG1478 also could inhibit the proliferation of endometrial cancer cells in a time-dependent manner and in a dose-dependent manner (P<0.05), but the inhibition rate of well differentiated cell line Ishikawa was higher than that in poorly differentiated cells AN3CA (P<0.05). Metformin+AG1478 also could inhibit the proliferation of endometrial cancer cells in a time-dependent manner and in a dose-dependent manner (P<0.05), and the inhibition of combined with metformin and AG1478 was stronger than that with a single application of drugs, but the inhibition rate of Ishikawa was higher than that in AN3CA (P<0.05).(2)RT-PCR method showed that different concentrations of metformin (0.01, 0.1, 1, 5, 10 mmol/L, respectively) for 24 hours, the expression level of EGFR mRNA in Ishikawa cells were respectively 0.74±0.03, 0.61±0.04, 0.46±0.03, 0.31±0.03 and 0.23±0.03, the expression level of EGFR mRNA in AN3CA cells were respectively 0.79±0.20, 0.61±0.03, 0.50±0.05, 0.32±0.03 and 0.26 ± 0.04, the inhibition effect showed a significant concentration-dependent manner (all P<0.01). (3) Western blot method displayed that the effect of metformin treated respectively 2, 4, 6 or 8 hours, there were not significant difference in the expression levels of t-EGFR protein and t-ERK1/2 between Ishikawa and AN3CA cells (all P>0.05). But the expression levels of p-EGFR and p-ERK1/2 protein were significantly lower between two groups (P<0.01), which showed a time-dependent manner(P<0.01). Conclusion Metformin could inhibit the proliferation of endometrial cancer cells, the inhibition is associated with the differentiation degree of cancer cells. Metformin could enhance the EGFR signaling pathway inhibitor AG1478 inhibition of endometrial cancer cells, which may inhibit EGFR expression of phosphorylated proteins to inhibit the phosphorylation of ERK1/2 proteins and then inhibit proliferation of endometrial cancer cells.

Objective: To investigate the improving effects of different moxibustion therapies on colonic injury in rats with ulcerative colitis (UC), and on the expression of Bcl-2 and Bax mRNA.Methods: Rats model of UC was made with immune methods and local stimulation. The models were treated with different moxibustion therapies 14 times, and then the expression of Bcl-2 and Bax mRNA were tested in the colonic tissue with fluorescent quantitative PCR. Results: (1)General scores of colon and histologic scores of injury were improved in all treatment groups except the model group (P＜0.05, P＜0.01); (2) The expression of Bcl-2 mRNA in the model rats of UC was higher than that in the normal rats (P＜0.01), whereas Bax lower (P＜0.01); (3) After treatments, the expression of Bcl-2 mRNA was lower in the herb cake-partitioned moxibustion, ginger-partitioned moxibustion, and garlic-partitioned moxibustion groups than that in the model group (P＜0.05, P＜0.01), and Bax mRNA in the herb cake-partitioned and ginger-partitioned groups was higher (P＜0.05). Conclusion: Herb cake-partitioned moxibustion, ginger-partitioned moxibustion, garlic-partitioned moxibustion, and mild moxibustion could improve the pathological injury in UC rats. Herb cake-partitioned moxibustion, ginger-partitioned moxibustion, and garlic-partitioned moxibustion could inhibit the expression of Bcl-2 mRNA and Bax mRNA in the colonic tissue of UC rats to regulate the ratio of Bcl-2/Bax mRNA.

Objective To investigate the effects of signal pathway inhibitors PD98059 and LY294002 on cell proliferation, apoptosis, expressions of phosphorylated extracellular signal-regulared kinase (p-ERK) and phosphorylated protein kinase B ( p-Akt) in endometrial carcinoma xenografts. Methods Human endometrial carcinoma Ishikawa cells were cultured in vitro. The effects of PD98059 and LY294002 on proliferation, apoptosis, and cell cycle distribution of endometrial cancer cells were detected by monotetrazolium ( MTT) assay and fluorescence-activated cell sorting technique. The models of xenografted tumor were established by the subcutaneous inoculation in 24 nude mice, and then they were randomly divided into 4 groups ( n = 6) , normal saline group, PD98059 group (PD group) , LY294002 group ( LY group) or PD98059 + LY294002 group ( PD + LY group) by intraperitoneal injections, respectively. The anti-tumor efficacy was evaluated by measuring tumor volume and tumor growth status. The histopathological change of tumor specimens was observed using HE staining and terminal deoxynucleotidyl transferasemediated dUTP-digoxigen in nick and labeling method (TUNEL) testing and the expression levels of p-ERK and p-Akt were detected by immunohistochemistry method. Results ( 1) The proliferation of Ishikawa cells were suppressed after treated by PD98059 and ( or) Y294002, in which A570 values of cells decreased showing both time-dependent and concentration-dependent manner ( LY294002: Fgroup = 9. 801, P = 0. 002; Ftime = 10. 398, P = 0. 001. PD98059: Fgroup= 8. 213, P = 0. 015; Ftime = 6. 839, P = 0. 036). Cell cycle distribution analysis revealed that percentage of Ishikawa cells at G0/G1 phase(Ftime =35.049, P= 0.004; Fgroup = 32. 024, P ＜0. 01) increased and percentage of S phase cells (Ftime = 7. 789, P = 0. 049; Fgroup = 30. 132, P ＜0. 01) decreased significantly. The percentage of apoptotic cells increased significantly among PD group, LY group and PD + LY group, in which there were significant difference [(63. 3 ±0.5)% vs (30. 7 ± 20. 1) % vs(40. 8 ± 1. 3) % ; F = 621. 059, P ＜ 0. 01]. (2) Compared with the control group, the increasing of transplanting tumor volume in the treated groups were obviously ( F = 23. 545 , P ＜ 0. 01) , and the inhibited rate of the tumor was higher in PD + LY group than that in PD group or LY group [(68 ± 9 ) % vs ( 32 ± 16 ) % or ( 38 ± 17 ) % ; F = 10. 283 , P ＜ 0. 05]. ( 3 ) HE staining shown that there were different degrees of necrosis for endometrial carcinoma cell in different groups. The apoptosis of tumor cells were significantly increased in treated groups by TUNEL testing [(13. 7 ± 1. 5)% , ( 14. 1 ± 1. 2)% , (29. 0 ± 1. 8 ) % ; F = 320. 344, P ＜ 0. 01]. Immunohistochemistry results demonstrated that the expressions of p-ERK and p-Akt in treated groups were lower than that in control group, of which LY + PD group was the lowest one. Conclusion The signal pathway inhibitors PD98059 and LY294002 could inhibit the growth of human endometrial carcinoma in vivo and in vitro, in which may induce cell apoptosis.
