Objectives To study the incidence of Trichomonas vaginalis(TV)infection in Chinese male patients with nongonococcal urethritis(NGU),to evaluate the sensitivity and specificity of urine-based and urethral swab polymerase chain reaction(PCR)detection,and to set up a method of non-invasive detection for male TV infection.Methods One hundred and five male NGU patients were collected from the STD clinic.Two urethral swabs were obtained from each patient,one for InPouch TV culture system,the other for PCR;one urine specimen(first-void urine or first-catch urine)was also collected for PCR detection.Culture was considered as the"gold standard".Compared with the culture,the sensitivity,specificity,positive predictive value(PPV)and negative predictive value(NPV)of two PCR detection were calculated.Results The positive rate of InPouch TV system detection was4.76%(5/105);the positive rate of urine-based PCR and urethral swab PCR detection was3.81%(4/105)and4.76%(5/105),respectively.In comparison with the culture,the sensitivity,specificity,PPV and NPV were80%,100%,100%and99%for urine-based PCR and80%,99%,80%and99%for urethral swab PCR.Conclusions TV is one of the etiological agent for male NGU,the positive rate of TV is4.76%in our study.The urine-based PCR detection has a higher sensitivity and specificity and provides a noninvasive method which is feasible in practice.

Objective To investigate the relationship between serum 25-hydroxyvitamin D level and gestational diabetes mellitus (GDM).Methods The fasting plasma glucose,fasting insulin,25-hydroxyvitamin D,and high sensitive C-reactive protein (hs-CRP) levels in the normal glucose tolerance group and gestational diabetes mellitus (GDM) group were measured.The homostasis model assessment insulin resistant (HOMA-IR) and homostasis model assessment β cell (HOMA-B) were calculated for assessing the insulin resistance and β-cell function.The relationship between 25-hydmxyvitamin D and hs-CRP,HOMA-IR,and HOMA-B were analyzed.Results The level of 25-hydroxyvitamin D in the GDM group [(2.16 ± 0.38) nmol/L] was significantly lower than that in the normal glucose tolerance group [(4.13 ±0.79) nmol/L](P =0.001).Serum 25-hydroxyvitamin D level was negatively correlated with hs-CRP (r =-0.448,P =0.002) and HOMA-IR (r =0.396,P =0.004),but was positively related with HOMA-B (r =0.495,P =0.001).Conclusions The serum 25-hydmxyvitamin D level remarkably decreases in GDM patients.Vitamin D deficiency may cause the functional damage of beta cell of islet,increase insulin resistance,and thus contribute to the development of GDM.

Objective To investigate the isolation and antimicrobial resistance of hypermutable Pseudomonas aeruginosa strains.Methods The cultured bacteria were identified by API 20NE system.The susceptibilities of bacteria were detected by disk diffusion method and the results were confirmed with the rules of NCCLS/CLSI.The hypermutable strains were identified byhigh concentration of rifampin-resistant growth assay.Results Among analyzed 100 strains,37 strains(37.0%) were hypermutable.The resistant rates of hypermutable strains to imipenem,meropenem,cefoperazone/sulbactam,piperacillin/tazobactam,ceftazidime,cephfime,aztreonam,amikacin and ciprofloxacin were significantly higher than those of non-hypermutable strains.The multidrug resistance rates of hypermutable strains were also higher than those of non-hypermutable strains.Conclusion The hypermutable strains of Pseudomonas aeruginosa sourced from chronic respiratory tract infections dominantly.The hypermutable strains were hyper-resistant and multidrug resistant to many antibiotics,so strengthened monitoring should be encouraged to control the prevalence of hypermutable Pseudomonas aeruginosa strains.

Objective To examine the effect and mechanism of sodium ferulate inhibiting P38 MAPK in macrophage on neurotoxicity which was mediated by fribrilar-amyloid-induced.Methods The isolated peritoneal macropohages were cultured.P38 MAPK protein in nuclear extracts was analyzed by Western blot and production of tumor necrosis factor-?(TNF-?) was detected by ELISA.For neuron-macrophage co-cultures,Microtubute-associated protein-2(MAP-2) expression was detected by immunocytochemical technique.The level of LDH in the medium was measured.Results The production of TNF-? and P38 MAPK protein in nuclear extracts increased significantly by incubation with A?25-35.LDH efflux in neuron-macrophage co-culture medium increased and MAP-2 expression decreased significantly(P

Objective To study clinicopathologic significance of eosinophils in human nasal polyps and the effect of corticosteroids.Methods 90 cases of nasal polyps were divided into two group randomly:corticosteriods group(n=30) with topical application of budesonide(BUD,400?g/d) for 14 days before endoscopic polypectomy,and control group(n=60) without BUD before surgery.All cases were stained with HE.Results Eosinophils showed higer in the group of nasal polyps than in the group of norm al inferior turbinate(P

Objective To investigate the relationship between the type of gliding contusion and its mechanism with site of force.Methods The site undergoing contusion and ways of force are respectively determined by skull anatomy location and details of these cases.Then,the 132 specimens of brain,which have been fixed by formalin,are sliced in coronal section and sagittal section and stained with HE,observed under microscope.ResultsGliding brain contusion could appeared at the top and bottom region of brain respectively.Top-injury type,were observed in 65 cases(49.24%),base-injury type,were found in 38 cases(28.78%).There were 29 cases(21.96%) in which contusion could be found at both top and base of brain,we called mixed type.We found that the injury area depend on the ways of force-act:the top-injury type mostly caused by the force on cupular part of pars zygomatica in acceleration,the base-injury type mainly caused by the force on occipitalia in deceleration and the mixed type caused by the force on the boundry of the calvaria and occipital in deceleration.Conclusion The type of gliding contusion is relevant with mechanism and site of force.

The extensive application of radiotherapy and the long survival of patients with malignant tumors have led to an in-creased incidence rate of radiation-induced osteosarcoma (RIOS), one of the most critical radiation-induced complications. Compared with primary osteosarcoma, RIOS has higher grade and poorer prognosis, which reduces the survival of patients with cancers. However, RIOS has not been fully understood in the clinical setting. This paper summarizes the latest progress at home and abroad, focusing on the incidence rate, risk factor, latency, and diagnostic criteria of RIOS. The molecular mechanism of RIOS is associated with the muta-tion of p53, the activation of the Wnt/β-catenin signaling pathway, and the superposition of multiple alleles. Furthermore, we discuss the differences in clinical characteristics, imaging findings, treatment, and prognosis between primary osteosarcoma and RIOS.
