OBJECTIVETo investigate the pathogenic infection and its drug resistance in expressed prostatic secretion (EPS) and its correlation with serum PSA, and provide some evidence for the systematic and normalized diagnosis and treatment of prostatitis.

METHODSThree EPS swabs were collected from each of the 320 prostatis patients following measurement of the serum PSA level, 1 for bacterial culture and identification, 1 for detection of Mycoplasma and drug sensitivity, and the other for examination of Chlamydia trachomatis antigen by colloidal gold immunoblot.

RESULTSTotally 244 strains were isolated from the 320 EPS samples, including 188 bacterial strains (dominated by Staphylococcus and sensitive to vancomycin or linezolid) and 44 Mycoplasma and Chlamydia strains (mainly Ureaplasma urealyticum and susceptible to josamycin or doxycycline). The serum PSA level was significantly higher in the pathogen-positive than in the pathogen-negative group ([6.98 +/- 0.56] microg/L vs [2.32 +/- 0.12] microg/L, P < 0.05).

CONCLUSIONProstatitis may lead to the elevation of the serum PSA level and the pathogens involved vary in their resistance to different antibacterial spectrums. Therefore, appropriate and individualized antibiotic therapy should be selected according to etiological diagnosis and the results of drug sensitivity test.

A growing number of children and adolescents are being diagnosed as Chiari malformation type Ⅰ (CM-Ⅰ) for behavioral disorders,developmental delay,seizures,or abnormal orpharyngeal function.The aim of this study was to compare the clinical characteristics,imaging findings and surgical outcomes of CM-Ⅰ in pediatric and adult patients.Between January 2014 and June 2017,84 patients with CM-Ⅰ underwent surgical treatment in our department.We divided the patients into two groups:pediatric group (n=1 1,age ＜18 years)and adult group (n=73,age ≥18 years).Data on clinical characteristics,imaging findings,surgical outcomes,and prognosis were retrospectively reviewed and compared between these two groups.For clinical presentation,scoliosis (36.4％) and developmental delay (36.4％) were more common in pediatric patients,whereas,sensory disturbance (58.9％) and motor weakness (41.1％) were more common in adult patients.Imaging findings showed that the incidence of hydrocephalus and craniovertebral junctional abnormalities was significantly higher in pediatric group than in adult group (P＜0.05).Compared to adult group,pediatric group showed a better improvement or resolution of syrinx and tonsillar herniation after surgical treatments (P＜0.05).The total Chicago Chiari Outcome Scale (CCOS) score in pediatric patients at the last follow-up was significantly higher than that in adult patients (P=0.002).In conclusion,the clinical characteristics and imaging findings appeared to be different in pediatric and adult patients with CM-Ⅰ.The surgical outcomes of pediatric patients were shown to be significantly better than those of adult patients.

This study was purpose to investigate apoptosis pathway of leukemia K562 cells induced by anticoagulant fraction from Agkistrodon acutus venom (AVVC-1). The mitochondrial transmembrane potential (ΔΨm) of leukemia K562 cells was detected by flow cytometry with JC-1 single staining. The expression of cytochrome C in the mitochondrial of leukemia K562 cells was analyzed by Western blot after AVVC-1 treatment. The distribution of cytochrome C in leukemia K562 cells was measured by immuno-fluorescence test. The results showed that the potential of mitochondrial membrane decreased after treatment with different concentrations of AVVC-1 (12.5, 25, 50, 100 µg/ml) for 6 h (P < 0.01). The expression level of cytochrome C protein in mitochondria obviously declined after treatment with 30 µg/ml AVVC-1 for 48 h, and the fluorescent intensity of cytochrome C in cytosol was enhanced at the same time. It is concluded that AVVC-1-induced K562 cell apoptosis is related with mitochondrial damage, and cytochrome C may be a useful agent for investigating human leukemia therapy by using AVVC-1.

OBJECTIVETo discuss the perioperative management of hemophiliacs A with orthopaedic complications.

METHODSTo regulate the injection of factor VIII concentrate in peroperative period by testing the level of factor VIII:C in 27 cases. The lever of factor VIII:C was improved to 30% - 50% at the day before the operation. To the severe patients, it was maintained at 58.5% - 89.3% during the operation and at 47.0% - 78.4% in postoperation. While to the gentle, it was maintained at 38.5% - 52.5% during the operation and at 29.2% - 52.3% in postoperation. The individualized surgical procedures were carried out, such as arthrocentesis, open knee synovectomy or arthroscopic synovectomy, evacuation or curettage of haematoma, debridements, internal fixation.

RESULTSAll patients were cured in 14 - 105 days by regulating the injection of factor VIII during the peroperative period. The usage of factor VIII was 1 200 - 70 250 IU.

CONCLUSIONWhile the hemophiliacs have orthopaedic complications, it is necessary to promise the factor VIII:C being maintained at the lever of hemostasis during the peroperative period. The hemophiliacs are endurable to the operation.

OBJECTIVESTo investigate the difference of BPH incidence in two groups.

METHODS309 cadres and 314 farmers over 60 years old in district of Wannan have been investigated. The investigation included prostate volume (V), IPSS, L, Qmax, residual urine (R) and dietary constituents.

RESULTSThe intake of animal protein in cadres is more than that in farmers (u = 24.10, P < 0.01), and the incidence rate of BPH is significantly higher (91.1% vs 11.8%, chi 2 = 24.64, P < 0.001). Logistic regression shows that the intake of animal protein has a parallel relationship with BPH.

CONCLUSIONSIn the district of Wannan, the incidence of BPH in cadres is significantly higher than that of farmers, and it may be correlated with the amount of animal protein intake.

OBJECTIVETo investigate the effect of ERCC1 gene on the repair capability of damaged DNA in lung cancer A549 cells induced by benzo[a]pyrene.

METHODSRecombinant plasmid expressing ERCC1 antisense RNA was constructed and transfected into A549 cells by Lipofectin reagent. The stable-transfected cell colonies were selected by hygromycin. Cell viability was determined by the MTT assay. The level of ERCC1 mRNA was measured by Northern Blot analysis. Single cell gel electrophoresis assay was applied to determine the cellular DNA damage and fifty cells for each group were counted.

RESULTSSeven positive colonies expressing ERCC1 antisense RNA were screened. There was no growth rate difference between the antisense-transfected cells and the parental cells. The endogenous mRNA level in transfected colonies decreased in varied degrees, i.e. 12% approximately 86% of that of the parental cells in Northern Blot assay. After 24 h treatment of 10 micro mol/l benzo[a]pyrene, the repair capability for DNA damage in transfected colonies was reduced to 29% approximately 71% of that of the parental cells. Also, a statistically significant correlation was observed between expression of ERCC1 mRNA and repair capability (r = 0.84).

CONCLUSIONAntisense ERCC1 RNA decreased the repair capability for damaged DNA in lung cancer cells induced by benzo[a]pyrene.
