Objective To investigate the relationship of nerve growth factor (NGF) between serum and follicular fluid in patients with polycystic ovary syndrome (PCOS), and its effect on pregnancy outcomes. Methods From December 2011 to November 2012, 65 PCOS patients suffered with in vitro fertilization-embryo transfer (IVF-ET) were included in PCOS group and 31 non-PCOS patients with IVF-ET were used as control group. The expressions of NGF in serum and follicular fluid were detected by ELISA on the injection day of chorionic gonadotropin (HCG). The expression levels of NGF in serum and follicular fluid were compared between PCOS group and control group. Results The NGF levels in serum[(14.38±0.42) ng/L] and follicular fluid[(9.61±0.49)ng/L] were significantly higher in PCOS group than those of control group[(11.39±0.38) ng/L and (7.55 ± 0.40)ng/L]. In PCOS group, NGF levels in serum [(14.22 ± 0.35)ng/L] and follicular fluid [(9.30 ± 0.31)ng/L] were significantly lower in pregnant group than those of non-pregnant group[(14.51±0.43)ng/L, (9.86±0.46)ng/L, P<0.01]. Conclusion The increased levels of NGF in serum and follicular fluid of PCOS patients contribute to the pathogenesis of PCOS. The high expression of NGF in serum and follicular fluid may be harmful to pregnancy in PCOS patients.

Objective To evaluate the clinical features of osteoarticular damage of patients with brucellosis,and to enhance the knowledge of clinical doctors.Methods The demographic characteristics,clinical presentations,accessory examination of 265 patients with brucellosis admitted from January 2011 to April 2014 in Ji'nan Infectious Diseases Hospital were retrospectively analyzed.Patients were classified into two groups:Patients with osteoarticular complications and patients without osteoarticular complications.Results Of the 265 patients,forty-six patients (17.36％) had osteoarticular complications.Spondylitis was the most common complication [50.00％ (23/46)],followed by sacroiliitis [41.30％ (19/46)] and peripheral arthritis [26.09％ (12/46)].Sacroiliitis was more common than other types of osteoarticular damage in females [21.74％ (10/46)],whereas in males spondylitis was more common [36.96％ (17/46)].Peripheral arthritis was more common in individuals under the age of 17 years old [4.35％ (2/46)],and sacroiliitis were more common in the ages of 18-60 years old group [23.91％(11/46)] and spondylitis were more common in over 60-year age group [30.43％ (14/46)].Patients with osteoarticular complications showed longer duration of illness from the onset of the symptoms to its diagnosis (median 45 days),compared to those non-osteoarticular brucellosis (median 30 days,Z =5.74,P ＜ 0.05).Conclusion Due to diversity of osteoarticular damage in patients with brucellosis,in case of a patient with long-term fever and osteoarticular symptoms,medical and epidemiological history should be inquired so as to strengthen early diagnosis and treatment of the disease based on combination with radiological findings.

Objective We sought to evaluate the effect of structured health education on quality of life and the end point of patients with coronary disease with evidence-based method.Methods The Cochrane Library,Cochrane Database of Systematic Reviews (CDSR),Medline (OVID),Pubmed and Web of Science were searched to collect the randomized controlled trials (RCT) which mentioned the structured health education to CHD patients,the quality of the RCTs was evaluated by Jadad Score,then effective data were extracted and analyzed by Meta-analysis with RevMan 5.2 software.Results A total of 12 eligible studies of RCT were included in the study with Jadad Score evaluations at B level or above.There were 20 476 cases in the intervention group,14 522 cases in the control group.Meta-analysis showed that the quality of life scores of the intervention group were significantly higher than those of the control group,weighted mean difference was 3.29,95％ CI (0.49-6.09).No significant difference was found in cardiac morbidity outcomes,re-hospitalization and the mortality rate,relative risk,95％ confidence interval were respectively 0.72(0.50-1.04),0.98(0.86-1.11),0.77(0.58-1.03).Conclusions The structured health education can improve the quality of life of patients with coronary disease,but has no obvious effect on the cardiac morbidity outcomes,re-hospitalization and mortality rate.We suggest transitional care to be carried out in future research to decrease the incidence rates of them.

Seizures may be the first or sometimes the only manifestation of patients with glioma in clinics. The aim of operation is to eliminate epilepsy far beyond mere resection of tumor mass. The underlyling mechanisms of glioma-associated epileptogenesis are poorly understood. Recently the theory of amino-acid like neurotransmitters in chemical synapse is gradually accepted. However, the molecular mechanisms remain to be further investigated on how glutamate release is regulated and how synaptic homeostasis in peripheral neurons is kept or disturbed. So detailed studies are needed to clarify specific molecular target and provide proper evidence for optimal antiepileptic drugs in glioma-associated epileptoge-nesis.

OBJECTIVE To understand the status of the hospital infection and risk factors,as well as the existing problems of infection management,to improve the surveillance method of incidence rate of hospital infection and strengthen the infectious precaution and control measures.METHODS By efforts of the professional staff of hospital,with cooperateion of the clinic personnel infection management group,all the patients in hospital were investigated when sampled from zero hour of the day before investigation to the zero hour of the day of investigation,according to the requirement of nosocomial infection rate to design the questionnaire.The data were analyzed.RESULTS The patients investigated in hospital were 638,from them 38 cases with hospital infections were found,the incidence and case-time rates of hospital infection were 6.0% and 7.4%,respectively.Respiratory infection was the most common.CONCLUSIONS Compared with the investigation method used previously,the current approach is easy and standardized.It also provides the credible reference to improve infection surveillance and management.

Objective To investigate the risk factors for castrate-resistant prostate cancer (CRPC) after prostate cancer treated with androgen deprivation therapy (ADT) within 1 year.Methods One hundred and thirty-one prostate cancer patients treated with ADT in our institute between Jan.2008 and Jan.2011 were selected for this study.Patients were followed up by telephone or in clinic,including serum testosterone,serum PSA,clinical symptoms,imaging studies,digital rectal examination (DRE),survival data,PSA nadir,time to PSA nadir and et al.We mainly studied the CRPC after prostate cancer treated with ADT within 1 year.In the 131 patients,the median age was 70 (ranged from 44-89) years.There were 13 patients (9.9％) less than 60 years,43 patients (32.8％) between 60 and 69 years,62 patients (47.3％) between 70 and 79 years,13 patients (9.9％) more than 80 years.The average body mass index (BMI) was 23.0 (ranged from 14.4-34.4) kg/m2.There were 10 patients less than 18.5 kg/m2,77 patients between 18.5 and 24.0 kg/m2,34 patients between 24.1 and 28.0 kg/m2,and 10 patients more than 28.0 kg/m2.The initial PSA was between 0.3 and 4 707.0 μg/L,there were 19 patients (14.5％) less than 20 μg/L,45 patients (34.4％) between 20 and 99 μg/L,67 patients (51.1％) more than 100 μg/L.One patient (0.7％) was in T1,39 patients (29.8％) in T2,59 patients (45.0％) in T3,32 patients (24.4％) in T4.5 patients (3.8％) were with Gleason score 4,13 patients (9.9％) were with Gleason score 5,24 patients (18.3％) were with Gleason score 6,51 patients (38.9％) were with Gleason score 7,26 patients (19.8％) were with Gleason score 8,9 patients (6.9％) were with Gleason score 9,3 patients (2.3％) were with Gleason score 10.Results There were 32 of 131 patients (24.4％) progressed to CRPC after treated with ADT within 1 year.In the CRPC group,there were 3 patients less than 60 years,15 patients between 60 and 69 years,12 patients between 70 and 79 years,2 patients more than 79 years; 3 patients were less than 18.5 kg/m2,19 patients were between 18.5 and 24.0 kg/m2,7 patients were between 24.0 and 28.0 kg/m2,3 patients were more than 28.0 kg/m2 ; 4 patients were less than 20 μg/L,6 patients were between 20 and 100 μg/L,22 patients were more than 100 μg/L; 4 patients were in T2,13 patients were in T3,15 patients were in T4; 2 patients were with Gleason score 6,11 patients were with Gleason score 7,11 patients were with Gleason score 8,6 patients were with Gleason score 9,2 patients were with Gleason score 10; 29 patients were with metastasis,3 patients without metastasis.Clinical stage (P =0.001),Gleason score (P＜0.001) and metastasis (P=0.011) were statistically significant between the CRPC within 1 year group and the rest group.Conclusions The clinical stage and Gleason score are the risk factors of CRPC treated with ADT within 1 year.The higher of the clinical stage and Gleason score,the greater risk to be the CRPC within 1 year.

Objective To explore the relationship between the antiviral effect and peripheral blood mononuclear cell (PBMC) hepatitis B virus (HBV) DNA when the patients reach the standard of withdrawal of antiviral therapy in chronic hepatitis B (CHB).Methods Ninety CHB patients treated with interferon(n=44) or nucleot (s) ide(n=46) who reached the standard of withdrawal of antiviral therapy were recruited.HBV DNA levels in PBMCs were tested at the end of treatment,and its relationship with serum HBV DNA level before treatment in PBMC HBV DNA positive group and negative group were compared.The correlation between HBV DNA in PBMCs at the end of treatment and relapse were explored.Measurement data were analyzed by student t test and enumeration data were analyzed by X2 test.Results Among 90 patients,67(74.4%) were PBMC HBV DNA negative at the end of treatment,and 23(25.6%) were positive.The serum HBV DNA positive conversion rate in PBMC HBV DNA negative patients was 13.4%,which were significantly lower than that in positive group (73.9%) (X2=30. 4873, P<0.01 ). There were no significant differences of alanine aminotransferase (ALT) levels when hepatitis flare (t=0. 8729, P=0. 3913) and relapse time (t=1. 9222, P=0. 0665) between PBMC HBV DNA negative group and positive group after withdrawal of therapy, while the serum HBV DNA rebound was greater in positive group than that in negative group (t=2. 7493, P=0. 0112). There were five patients who achieved hepatitis B surface antigen (HBsAg) seroconversion, whose PBMC HBV DNA were all undetectable, and none relapsed during follow-up for 6-12 months. The pretreatment HBV DNA as level in PBMC HBV DNA positive was (7.2±1.1) lg copy/mL, which was much higher than that in negative group[(5.2±2.1) lg copy/mL] (t=4. 3557, P<0.01). Conclusions In patients who reach the standard of drug withdrawal,PBMC HBV DNA at the end of treatment is an important predictor for durability of antiviral therapy in CHB.

Objective To investigate the expression of Dysadherin and analyze its role in renal clear cell carcinoma (RCCC).Methods RT-PCR and immunohistochemical were used to detect the expression of Dysadherin in 60 cases of fresh RCCC and 60 adjacent normal renal tissues(male 35,female 25; age 37-78,median age 61; ＞7 cm 24,≤7 cm 36; Ⅰ/Ⅱ 39,Ⅲ/Ⅳ 21).Results Dysadherin mRNA expression in RCCC tissues (2.0043±0.2890) was higher than that in adjacent normal renal tissues (0.8461 ±0.2479) (t =6.8020,P ＜ 0.05).Dysadherin expression was associated with nuclear grade.The expression of Dysadherin in nucleus grade Ⅲ and Ⅳ tumors were significantly higher than that in nucleus grade Ⅰ and Ⅱ tumors [the mRNA expression were 4.6224±0.3194,2.7780±0.2288,the positive rates of protein were 64.1％ (25/39),95.2 ％ (20/21) (t =6.5750,x2 =5.495,P ＜ 0.05)].There was no association between the expression of Dysadherin with sex (t =1.0530,x2 =0.023),age(t =0.0511,x2 =0.089) and tumor size (t =1.0330,x2 =0.370) (P ＞ 0.05).Conclusion In RCCC,Dysadherin expression is positively associated with tumor aggressiveness based on grading.It seems that Dysadherin may be a valuable prognostic marker in RCCC.
