Objective To evaluate the efficacy of treating female conyloma acuminatum with the CO2 laser under colposcopy guidance and traditional Chinese medicine sticking therapy.Methods Female patients with conyloma acuminatum whose diagnosis were confirmed by pathologic examination,were randomly assigned to two groups:a treatment group of 100 cases and a control group of 80 cases,with no statistical differences of the age and the duration.The treatment group was treated by CO2 laser to remove conyloma acuminatum and subclinical damage,and then by TCM wart-washing decoction sticking after operation; The control group was treated by CO2 laser to remove the wart,and then by TCM wart-washing Decotion for fumigating after operation.Results The curative rate of the treatment group and the control group was 79.00％and 60.00％ respectively.There was significant difference between the two groups (x2=7.723,P＜0.01).Conclusion The treatment of CO2 laser under colposcopy guidance combined with Chinese medicine sticking therapy is effective for female conyloma acuminatum.

Hepatitis C virus (HCV)infection is one of the most common causes of chronic hepatitis,liver cirrhosis,and hepatocellular car-cinoma.MicroRNAs (miRNAs),a class of small,non -coding RNA,are involved in a variety of physiological and pathological processes in human bodies.The mechanism by which miRNAs regulate HCV replication is described,and the effects of liver -specific microRNA -122 antagonists on hepatitis C antiviral therapy are discussed.Our study indicates that miRNAs play an important regulatory role in HCV ex-pression.Targeting miRNAs may be a potential therapeutic approach for treating HCV infection,but further studies are still in need.

From Aug 2014 to July 2015, researches in the field of gonadal diseases have achieved rapid advances with image technology, the technology of biochemistry, and molecular biotechnology progressing. Considerable literatures concerning the pathogenesis, gene and clinical diagnosis, and treatment of gonadal diseases have been published. We reviewed and analyzed some more instructive literatures for clinical practice, proposed some suggestions, and the work plans for the clinicians.

Objective To explore the relationship between the risk of amyotrophic lateral sclerosis (ALS) and exposure to rural environments and pesticide.Methods Studies relevant to rural residence,farmer occupation,pesticide exposure and ALS were identified from the databases including Embase,Ovid Medline,Pubmed,Cochrane Library,Wanfang data,Chinese BioMedical Literature Database,Chinese National Knowledge Infrastructure,China Science and Technology Journal Database up to March 2015.Quality of studies was assessed according to the Newcastle-Ottawa Scale (NOS).Analysis of data and publication bias was performed with software Revman 5.3.Results A total of 24 case-control studies and 3 cohort studies were included into the analysis.The NOS scores of all studies were ≥6.The risk of ALS was associated with pesticide exposure (OR =1.41,95％ CI 1.28-1.56) and farmer occupation (OR =1.42,95％ CI 1.29-1.57),but not associated with rural residence (OR =1.21,95％ CI 0.97-1.51).Subgroup analysis of pesticide exposure and ALS revealed that males (OR =1.75,95％ CI 1.39-2.21) had a higher risk than females (OR =1.53,95％ CI 1.13-2.08),and the risk estimate was higher in studies using E1 Escorial standard (OR =1.68,95％ CI 1.45-1.95) than studies not (OR =1.23,95％ CI 1.08-1.40).The meta analysis had a slight publication bias.Conclusions Our findings support pesticide exposure might increase the risk of ALS.Given that farmers always have high levels of pesticide exposure in their work,they should decrease their exposure level or take proper precautions to lower the risk of ALS.

Objective To assess systematically the effect of problem-based learning (PBL) versus traditional methods in nursing students.Methods Relative literature was searched by computer at home and abroad.according to the inclusion and the exclusion criteria,which were analyzed by RevMan5.2 software,and literature selection and repetition were used according to the Note Express software.Results A total of 9 studies of randomized controlled or not randomized controlled trial were brought into the study by random effects model.A total of 1 187 were collected into the study,574 in the experimental group and 613 in the control group.According to subgroup analysis showed by measurement scale,problem-based learning (PBL) can significantly improve the critical thinking ability of nursing students.The results had high stability and reliability.Conclusions PBL teaching method can significantly improve the critical thinking ability of nursing students,and provide a better learning method for clinical teachers and students,which is worthy of further promotion.

Objective To study clinical efficacy of ulinastatin combined with naloxone in patients with cardiogenic shock(CS) after acute myocardial infarction (AMI).Methods Eighty patients with CS after AMI were randomly divided into routine treatment group (n =19),ulinastatin group (n =20),naloxone group (n =21) and ulinastatin combined with naloxone group (n =20).The levels of serum cardiac troponin I (cTnI),brain natriuretic peptide(BNP),tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6)were measured before and a week after treatment.In the meantime,recovery time of shock,the average hospitalization days and 28-day mortality rate were recorded.Results After the treatment,the levels of serum cTnI,BNP,TNF-α and IL-6decreased in all groups(P ＜ 0.01),and there was significant difference on the decreasing degree of cTnI,BNP,TNF-α and IL-6 in ulinastatin combined with naloxone group when compared with those in routine treatment group,ulinastatin group and naloxone group(cTnI:(1.04 ± 0.17) ng/L vs.(2.06 ± 0.15) ng/L,(1.59 ± 0.16)ng/L,(1.97 ± 0.14) ng/L; BNP:(143.21-56.94) ng/L vs.(261.07 ± 71.43) ng/L,(203.46 ± 65.73) ng/L,(252.96 ± 68.85) ng/L; TNF-α:(13.42 ± 8.93) ng/L vs.(31.21 ± 12.32) ng/L,(20.39 ± 11.08) ng/L,(28.98 ± 11.76) ng/L ; IL-6:(37.58 ± 11.14) ng/L vs.(80.46 ± 27.15) ng/L,(59.84 ± 20.72) ng/L,(76.15 ±26.45) ng/L; P ＜ 0.01).The recovery time of shock,the average hospitalization days and 28-day mortality rate in ulinastatin combined with naloxone group were significantly lower than those in routine treatment group,ulinastatin group and naloxone group(recovery time of shock:(7.16 ± 1.52) d vs.(11.43 ± 2.40) d,(8.05 ±1.81)d,(8.74 ± 1.98)d;the average hospitalization days:(15.03 ±3.23)d vs.(22.64 ±4.18)d,(18.93 ±3.97)d,(19.21 ±3.94)d ;28-day mortality rate:(41.62％ vs.61.20％,50.74％,52.31％ ; P ＜0.01)).Conclusion The application of ulinastatin combined with naloxone can effectively inhibit the cardiac injury and inflammatory response,promote the recovery of circulation function and improve prognosis in patients with CS after AMI.

Objective:Defensins from human neutrophils exhibit a broad antimicrobial activity.The transfection of the gene fused by human neutrophil peptide 1(HNP1) with the J chain into other cells may induce the in vitro expression of HNP1 to play antimicrobial roles.The authors analyzed the influencing factors on the expressed proteins of HNP1 and the J chain gene in COS-7 cells.Methods: Western blot was used to analyze the technical factors influencing the HNP1 protein expression.Results: Recombinant J-HNP1 was expressed in the cells successfully.Conclusion: The expression of J-HNP1 can be detected inside and outside the cells by Western blot.

[Objective]To investigate results of surgical treatment of intradural tumors of the cervical spinal cord.[Method]Twenty-one cases with cervical intradural tumor were treated surgically under posterior approach from 1999 to 2005,all patients were performed cervical laminae resection before tumor resection,and some received internal fixation.All patients were followed up for 8 months to 38 months respectively.All the clinical materials were analyzed retrospectively.[Result]All patients survived the operation,symptoms disappeared 13,relieved 7 and deteriorated 1.Total resection in 15 cases,subtotal 4 cases and partial 2 cases.[Conclusion]To succeed the operation,it is very important to make clear the location and size of the tumor and the relationship between the tumor and spinal cord;in order to gain total resection of tumor,both careful protection of spinal cord and vertebral artery and intraspinal cannal veins are essence.
