Objective:To explore the clinical pathogenisis of urination dysfunction in aged males and evaluate the bladder and urethra function by urodynamics studies.Methods:Clinical etiological diagnosis and urodynamic studies were performed in 304 aged male patients with urination dysfunction.Results:Among the entire 304 patients,186(61%)patients had benign prostatic hyperplasia.21(7%) patients had other male genitourinary system diseases.77(25%)patients had no male genitourinary system diseases.Urodynamic studies diagnosed:132(43%)patients had bladder outlet obstruction;119(39%)patients had detrusor instability;187(61%)patients had detrusor muscle with poor compliance;77(25%)patients had detrusor muscle weakness;38(12%)patients had detrusor-external sphincter dyssynergia.Conclusion:Multisystem and multi-species diseases can cause urination dysfunction in aged males.Urodynamic studies is efficacious for the cognition of the bladder and urethra dysfunction.Clinical etiological diagnosis combined with urodynamic studies can make the diagnosis of urination dysfunction in aged males more precise.

Objective To study the clinical,image and pathological features of cerebral gliomatosis.Methods 2 cases with cerebral gliomatosis underwent routine MRI scan, contrast enhance MRI scan and pathologic examination of the lesions. Their clinical manifestations were observed during the past 2 years.Results Main clinic features of the 2 patients were headache, dizziness, nausea, vomit, diplopia, hemiplegia, hemianesthesia and ataxia. Cranial MRI scan showed long T 2 signals in the bitemporal lobes, biparietal lobes, corpus collosum, thalamus, caudate nucleus and putamen. Brain stem and cerebellum were also involved in 1 patient. The borders of the lesions were unclear and no mass-effect phenomenons were found. Contrast enhancement occurred only in 1 patient after Gd-DTPA injection. The biopsies in the 2 patients showed diffuse infiltrative growth of most astroglioma cells. The shape of nucleus was round or ellipse and the staining of nucleus was comparatively deep. Cleavage of nucleus was seldom. The 2 patients died in 4 to 6 months after the onset of the disease.Conclusions MRI scan and pathologic examination are essential diagnostic methods for cerebral gliomatosis. The prognosis of cerebral gliomatosis is poor.

Objective To determine the relationship between serum vitamin B_(12)(VB_(12))level and multiple sclerosis(MS).Methods The pertinent articles of the VB12 and the case control studies of MS were retrieved comprehensively by manual retrieval and computer retrieval.The methodology quality of the retrieved artilces were evaluated,and the arcb'cles were screened.Heterogeneity test was performed.The valid data was extracted and analyzed by Stata 10.1.Results In this study,9 studies were included.A total of 807 subjects were enrolled,including 414 patients and 393 controls.The Meta-analysis showed that the serum level of VB_(12) in patients with MS was lower than that in controls(standardized mean difference-0.24,95% CI-0.39 to-0.10).The sensitivity analysis indicated that the result of meta-analysis was reliable.Conclusion The serum level of VB_(12) might be associated with MS,and the deficiency of VB_(12) may contribute to the development of MS.

Objective To study the pathologic and molecular genetic characteristics of Chinese patients with oculopharyngeal muscular dystrophy(OPMD).Methods The ultrastructural muscle biopsies in 6 patients were carried out by using transmission electron microscopy.The DNA was obtained through blood samples from patients(n=11) and the at-risk individuals(n=16).Amplification of the PABPN1 gene mutation region was performed by polymerase chain reaction(PCR).The sequences were obtained and compared with the genomic sequence of the human PABPN1 gene.Results Intranuclear inclusions(INIs) were found by electron microscopy in 4 patients,and the rate of appearance was 18%,20%,34% and 40%.Sequence analysis of exon 1 of PABPN1 gene showed abnormal expansions of the GCG-repeat—(GCG)_8 and(GCG)_(10) in 9 patients.Conclusions INIs might be found by electron microscopy in muscle biopsies of OPMD patients.The rate of appearance of INIs should have positive relationship with the amount of the GCG-repeat.PABPN1 gene mutations might be present among Chinese patients with OPMD,and should have a negative relationship with the age of onset.

OBJECTIVE:To investigate the effects of total glucosides of paeony(TGP) on the expressions of CD4+ T lymphocytes and IL- 6 in prostatic tissues of rats with chronic abacterial prostatitis(CAP) and to study its action mechanism on CAP.METHODS:36 SD rats were randomly divided into three groups:CAP control group(n = 12 rats),low dose CAP + TGP group(n = 12) and high dose CAP + TGP group(n = 12).The expressions of CD4+ T lympholeukocytes and IL- 6 in prostatic tissues of rats were detected by immunohistochemistry after medication were investigated,and the changes in histopathology of prostatic tissues.RESULTS:Significant inflammatory condition was noted in CAP control group;improvement of glandular structure and infiltration of small number of inflammatory cells were noted for low dose TGP group.In high dose TGP group,inflammation was abated markedly and there was diffused distribution of a few number of inflammatory cells. As compared with CAP group,the expressions of CD4+ T lymphocytes and IL 6 were down regulated significantly in both the high dose and low dose TGP groups(P

Objective To evaluate the efficiency of Finasteride in treating inflammatory hemospermia and approach the mechanism of action. Methods 56 cases of hemospermia were randomly divided into two groups. The experimental group (n = 30) was treated with Finasteride combined with antibiotic for 1 month, while the control group(n=26) was treated only with antibiotics for 1 month. The expression of VEGF in sperma was de-tected by enzyme linked immunosorbent assay (ELISA) in pretherapy and post-treatment. Results Hemospermia disappeared in 28 cases of experiment group(28/30, 93.3%) and in 17 cases of control group(15/30,57.7%),with significant difference. The expression of VEGF degrade in post-treatment. Conclusions Hemospermia can be treated more effective with finastefide combined with antibiotics. The mechanisms may be associated with Finas-teride can reduce VEGF synthesis and inhibit the microvascular formation.

Objective To report clinical symptoms of a Chinese pedigree of familial paramyotonia congenital (PMC) with progressive myopathy (PM), and investigate the mutations of hot spots in the adult skeletal muscle sodium channel α-subunit (SCN4A). Methods The medical history and clinical phenotype of the patients from this large family with PMC were collected. Insertional and spontaneous activity were recorded by routine electromyograph (EMG), and the exercise test (ET) and cool water test were also performed on some patients during episodes. The mutations of SCN4A were screened by PCR-SSCP and DNA sequencing in affected and unaffected members. Results The family is a four-generation kindred with 15 members affected by severe, homogeneous paralysis periodiea paramyotoniea pheuotype. The onset was early, and almost all patients developed severe progressive myopathy by middle age. Routine EMG shows myotonia discharge in all affected subjects. The compound remarkably motor action potential (CMAP) decreased more than 40% after ET with greater decreases in cool water test than in ET. The mutation screening study revealed a missense mutation (Met1592Val) in SCN4A in patients. Conclusions Autosomal dominant inheritance pattern with complete penetrance was observed in this family. The phenotype is in accord with that reported in other ethnic populations with more severe symptoms. The ET and cool water tests may be used as an easy and reliable diagnostic method. Our research supports that periodic paralysis and paramyotonia can be caused by the same mutation in SCN4A. Mutation Met1592Val is a hotspot for mutation screening in patients with PMC accompanied by PM in the Chinese population.

By means of the reform of curriculum systems and the overall optimizing of teaching contents, the overlapping and duplication in the existing curricula can be reduced and the teaching effects can be improved.

Objective To discuss the clinical features, diagnosis and therapy of primary adrenal lymphoma (PAL) . Methods Two patients (65-year old and 52-year old respectively) who complained vague pain were analyzed. Occupying lesions in adrenal gland were discovered by computed tomography (CT) and diagnosed by needle biopsy and laparoscopic surgery. Results The two patients in our hospital were diagnosed as nonHodgkin's lymphoma. They were treated with chemotherapy and one of them was partial response. Literatures on PAL were reviewed. In the literature, 7 of the 65 patients achieved complete response, 15 partial response, 43 death or unspecified and the survival duration was 3 days to 26 months. Conclusions Most of PAL are bilateral, without specific clinical characters. Neele biopsy is the first choice to make the diagnosis. The therapeutic modalities for PAL include surgery, chemotherapy, surgery followed by chemotherapy as well as radiation therapy. The prognosis of PAL is poor if other organs are involved.
