Sperm DNA fragmentation index (DFI) refers to the percentage of DNA strand breaks in the total sperm. Many studies suggest that elevated DFI can lead to male infertility and early spontaneous abortion. High-DFI patients are more likely to fail in assisted reproduction and preliminary treatment or prevention methods have been developed for this population. This review focuses on the impact of DFI on clinical pregnancy outcomes and progress in the studies of its treatment.

Objective: To study the clinical features of primary biliary cirrhosis (PBC) in order to facilitate cognition of the disease. Methods: Clinical data of 42 patients clinically and/or histologically diagnosed with PBC were reviewed. Anti mitochondrial antibody (AMA) negative/positive patients as well as the patients who were/were not associated with Sj?gren Syndrome (SS) were compared in terms of clinical, biochemical and immunological features. Results: Among the 42 patients, 78.6%(33/42) of the cases were females; the mean age at diagnosis was (61.1?10.8) years. The most frequent symptoms were fatigue. Serum alkaline phosphatase (ALP), ?-glutamyltranspeptidase (?-GT) and total bile acid (TBA) levels were markedly elevated in the majority of the patients, whereas ALT and AST levels were mildly to moderately elevated. Thirty-one patients had a total bilirubin (TBil) level above normal. The levels of TBil and prothrombin time had positive correlationship with years of the course (P=0.000, r=0.696; P=0.005, r=0.424), whereas serum albumin level had negative correlationship with years of the course (P=0.002, r=-0.462). Thirty-seven patients had elevated serum IgM and 34 patients were AMA/AMA-M2 positive. AMA negative and AMA positive patients were similar in terms of clinical manifestations and liver biochemistries findings. Serum IgM and IgA levels were significantly lower, whereas total cholesterol level was higher in AMA negative patients when compared with AMA positive cases. Fifteen cases were associated with SS, which were similar in terms of clinical, biochemical and immunological features when compared with the PBC patients were not associated with SS. Conclusion: PBC is mostly found in middle aged and old women. Elevated serum ALP, TBA and ?-GT levels together with positive AMA/AMA-M2 can help to diagnose PBC. AMA negative PBC patients are characterized by relatively lower serum IgM and IgA levels and higher total cholesterol level. PBC patients who are associated with SS have not substantial differences in the clinical, biochemical and immunological spectra of the disease.

Objective To compare the changes in serum levels of high sensitive C-reactive protein (hs-CRP)and uric acid(UA)before and after atorvastatin treatment for the patients with both essential hypertension and hypercholesterolemia,and to evaluate its effects on blood pressure and left ventricular remodeling.Methods One hundred and twenty-six hypertensive patients complicated with hypercholesterolemia were randomized into group A with amlodipine 10 mg/d(n = 65)and group B with amlodipine 10 mg/d plus atorvastatin 20 mg/d(n = 61),for three months continuously.Serum levels of total cholesterol(TC),low-density lipoprotein-cholesterol(LDL-C),high-density lipoprotein-cholesterol (HDL-C),triglyeerides(TG),hs-CRP and UA,as well as blood pressure,were determined for both groups before and after treatment.Left ventricular posterior wall thickness(LPWT)and interventricular septum thickness(IVST)were measured by echocardiography and left ventricle mass index(LVMI)was calculated.Results Serum levels of TC,LDL-C,HDL-C,TG,hs-CRP and UA decreased significantly in gr6up B after three-month treatment with atorvastatin,while serum level of HDL-C increased significantly. And,systolic and diastolic blood pressure reduced in both groups,but significantly lower in group B than those in group A,after treatment(P

Objective To investigate the Human papillomavirus(HPV)infection in different age groups of women in Shenyang, and explore its correlation with cervical biopsy diagnosis.Methods 7 311 women aged 13-85 did HPV test and thin-cytologic test (TCT)in the hospital.Some of them had biopsy detection under electronic colposcopy,and the pathological diagnosis was the golden standard for the diagnosis of cervical lesions.SPSS18.0 statistical software was used for all statistical analysis.Results The infection rate of <30 years old women was significantly higher than that of 30 - <40,40 - <50,≥50 years old women (P <0.05).The most prevalent high-risk HPV genotype in Shenyang were subtype 16,52,58,53,33,31 and 18,and the most prevalent low-risk HPV subtypes were 81,11 and 6.The former 4 subtypes of high-risk HPV infection accounted for 67.3% of all high-risk infection.As to the 4 subtypes with higher infection rate,the infection rate of ≥40 years old women was higher than that of <40 years old(χ2 =20.29,P =0.00).The top two low-risk HPV subtypes accounted for 74.8% of the infections.The mean age of the ICC patients were 48.3,which was statistically different from the other groups(P <0.05).Cervical lesions occured mostly in 40-49 years old,which accounted for 37.1% and was higher than the other agees(P <0.01).HPV16 infection rate increased with the severity of cervical lesions.Conclusion HPV DNA genotyping is a necessary methord for cervical cancer screen,an effective com-plement for precancerous lesions diagnosis which was missed in cytology test,and also an indispensable test for CIN treatment and follow-up after operation.

Objective To provide reference for anti-infection drugs in Zunyi area by analyzing the etiological characteristics of children with severe pneumonia.Methods The sputum, throat swabs and serum of children with severe pneumonia in pediatric intensive care unit of our hospital from January 2014 to December 2015 were collected in this study.The pathogen species which caused severe pneumonia were detected and identified by the method of pathogen culture,and typical pathogens were detected by RT-PCR and indirect immunofluorescence.Results A total of 337 children with severe pneumonia were included,the pathogen positive rate was 86.65%(292/337).The rate of viral infection(37.32%)was the highest,followed by bacterial infection accounting for 28.42%,then the mixed infection accounting for 27.74%,and the mycoplasma pneumoniae infection accounting for 6.50%.The respiratory syncytial virus type B accounting for 28.44% was the most common in viral infection,and there were significant differences in age distribution(P<0.05),the children under 3-years-old,especially the infants under 1-year-old had the highest susceptibility.Viral infection had certain seasonality,compared with spring and winter,autumn and winter(November to April) had higher viral detection rate and the difference was statistically significant(x2=29.28,P=0.001).The escherichia coli was the most common in bacterial infection,accounting for 21.69%.Klebsiella pneumoniae,Escherichia coli were more common in neonates and infants under 1-year-old,Haemophilus influenzae occured in 1~3 years old children,Streptococcus pneumoniae infection could occur in any age.Conclusion Viral infection is the most common pathogen in children with severe pneumonia in Zunyi area followed by bacterial infection,which is more common in children under 1-year-old,and with the high incidence in autumn and winter.Bacterial infection is more common in children over 3 years of age.Bacterial and viral mixed infection is common in children under 3 years of age,especially in children under 1-year-old.

OBJECTIVETo explore the procedures of dynamic infusion cavernosometry and cavernosography (DICC) and their application in the diagnosis and classification of venous erectile dysfunction (VED).

METHODSThis study included 103 ED patients, aged 20 to 43 years, highly suspected of VED, with disease courses of 4 months to 6 years. DICC was performed and analyses were made on the results, especially the parameters of flow-to-maintain (FTM) and pressure decay (PD) in the corpus cavernosum.

RESULTSBased on the parameters of FTM and PD, 21 of the patients were normal, 5 were suspected of VED, 39 had mild VED, 25 had moderate VED, and 13 had severe VED. Penile subcutaneous hematoma was found in 4 of the patients, all recovered after 3 to 5 days, with no other complications.

CONCLUSIONDICC is a reliable, safe and minimally invasive method for the diagnosis and classification of VED.

ObjectiveTo investigate the efficacy of co-infusing cord blood (CB) as the third party cells on graft versus host disease (allo-GVHD) prophylaxis after unrelated or haploidentical donor allogeneic hematopoietic stem cell transplantation (allo-HSCT).MethodsFrom 2007 to 2011,41 patients receiving unrelated or haploidentical donor allo-HSCT were analyzed retrospectively.Twenty-five patients received one unit of HLA 4/6-6/6 matched CB one day before SCT as CB group,and median MNC dose was (1.64 ± 0.49) × 107/kg.Sixteen cases not receiving CB served as control group.All patients received antithymocyte globulin,cyclosporine,methotrexate,and mycophenolate mofetil as GVHD prophylaxis.The incidence and severity of aGVHD,and treatment-related mortality were compared between two groups.ResultsThe main clinical characteristics in both groups were comparable.The cumulative incidence of aGVHD in CB group and control group was 44.0％ versus 68.8％ respectively (x2 =2.403,P＞0.05).The cumulative incidence of grades Ⅲ to ⅣV aGVHD in CB group and control group was 16.0％ and 37.5％ respectively (x2 =2.445,P＞0.05).The 100-day treatment-related mortality in CB group and control group was 12.0％ and 12.5％ respectively (x2 =0.002,P＞0.05).ConclusionCord blood as the third party cells might reduce the incidence and severity of aGVHD in unrelated or haploidentical donor HSCT.The efficacy and the mechanism of this strategy need to be further explored by prospective randomized controlled trials.

Objective To evaluate the safety of coronary intervention using iodixanol in patients with diabetic renal insufficiency.Methods Clinical data of 97 patients with diabetic renal insufficiency undergoing coronary intervention during June 2004 to June 2006 were retrospectively analyzed,50 of them with iodixanol,an iso-osmolar contrast medium (iodixanol group),and 47 with iopromide,a hypotanic contrast medium (iopromide group).Judkin's coronary angiography showed 167 diseased vessels in the patients,65 in anterior descending branches,44 in circumflex branches,and 58 in right coronary arteries. Levels of serum creatinine and blood urea nitrogen were determined before percutaneous coronary intervention (PCI),on the day of the procedure,the 3rd and 7th days after PCI,respectively,as well as radiocontrast media-induced nephropathy (CIN) was observed.Results Totally,192 drug-eluting stents were successfully implanted in 167 diseased vessels,and all patients' angina pectoris symptom disappeared soon after the procedure,with a full success.No acute or subacute stent thrombosis and major adverse cardiac events (MACE) occurred.Two patients (4%) in iodixanol group and 10 (21%) in iopromide group got CIN,with a statistical significance (P
