Objective: To study the long-term effect of Tangshan earthquake on psychosomatic health of paraplegic suffers. Method: 64 paraplegic suffers of Tangshan earthquake and 64 normal controls were interviewed and assessed with self made questionnaire for psychosomatic health, SCL-90, SAS, SDS, CMI (Cornell Medical Index) and SSRS (Social Support Rating Scale). Results: 6 patients (9%) were diagnosed as PTSD according to CCMD-2-R, this rate was higher than that of normal citizen experienced the earthquake. 32 patients had Acute Stress Reaction. At present, patients' group had poorer mental health than control reflected by SCL-90, SAS, SDS and CMI. Conclusion: The severity of trauma both mentally and physically has great influence on mental health of suffers even after 25 years.

Objective To provide patients and medical personnel with quality, highly effcient, and reasonably priced logistical services by forming specialized entities of logistical services and following the path of specialization, intensity and market mechanisms. Methods The principles of overall planning, phase-by-phase implementation and steady promotion were adhered to and the functions of logistical management and services were separated in accordance with the ideas of separating management and operation and the goals of outsourcing logistical services. Results The traditional models of "being small but complete" and "a hospital setting up a society" were transformed and new models of logistical management and services were established. Conclusion There has emerged a new pattern of outsourcing logistical services, with both sides sharing resources and complementing each other's advantages.

Objective:To explore the relative factors of hospitalized schizophrenics with metabolic syndrome. Methods: Patients data were collected by the way of face-to-face questionnaire to patients or their guardians, consulting patients medical record, checking physical or laboratory examination. Information include age, duration of the disease, the classification of antipsychotics and dosage, fast plasma glucose, plasma lipids, blood pressure, etc of hospitalized schizophrenics. The relative factors of metabolic syndrome were analyzed. Results; Among 797 schizophrenics, there were 153 cases (19. 2% ) suffered from metabolic syndrome. Single-factor analysis showed that the patients with longer duration of the disease, taking clozapine, etc, were at high risk of metabolic syndrome, and sex didnt relate to metabolic syndrome; Logistic regression analysis appeared that metabolic syndrome correlated with age, clozapine, CRP concentration, etc. Conclusion: The possible risk factors causing metabolic syndrome in schizophrenia include, duration of the disease, etc.

Objective To detect the relationship between CAG repeat in IT15 gene and clinical manifestations of Huntington's disease (HD).Methods Non-denaturing polyacrylamide gel electro- phoresis method was used to detect CAG repeat.Clinical manifestations were scored by UHDRS and MMSE. Results Genotypes of IT15 were heterozygous in all 29 HD patients.CAG repeat in the HD chromosome, being 42—62,13—28 in normal chromosome,was inversely correlated with age of onset (r=-0.539,P

Objective To explore the causes of readmission after prostatectomy for BPH and to discuss the treatment approaches. Methods A total of 106 cases who were eligible for the study were reviewed.47 cases had residual and recurrent adenoma;of these cases,42 underwent TURP and 5 open prostatectomy again.32 cases developed urethral stricture;of these cases 27 underwent transurethral cold knife incision plus electric resection of scar and 3 urethral orifice reconstruction and 2 suprapubic cystostomy.11 cases who had experienced bleeding after TURP underwent transurethral bladder washing and coagulating.7 cases had neuropathic bladder dysfunction;of these cases 2 underwent transurethral bladder neck circle muscle resection,3 intermittent self-catheterization and 2 suprapubic cystostomy.6 cases had prostatic cancer;of these cases 1 underwent radical prostatectomy,3 palliative TURP plus orchiectomy and 2 orchiectomy.2 cases had incontinence after TURP;of the 2 cases 1 used external collecting device and 1 was transfered to other hospital for surgery.1 case had abdominal incision hernia and then underwent hernia repair. Results Among 106 cases, 97 cases underwent operations and of them 84 (86.6%) cases achieved successful results.The follow-up time was 6 months to 15 years with a mean of 5 years and 8 months.9 cases with urethral stricture required regular urethral dilation after surgery.4 cases who had had unsuccessful surgery underwent suprapubic cystostomy.Other 9 cases did not undergo operations due to poor health and other reasons. Conclusions Correct preoperative diagnosis, rational surgical type and adequate intraoperative and postoperative management are key to preventing readmission. Transurethral surgery is most favorable treatment choice for readmitted patients after prostatectomy for BPH.

Objective To investigate the regulatory effect of transforming growth factor-? 1 (TGF-? 1)on the proliferation and apoptosis of human prostatic epithelial cells in vitro. Methods The primary culture was prepared by collagenase dissociation of minced prostatic tissue obtained from 8 BPH patients (53 to 70 of age) on open prostatectomy and from 5 organ donors (23 to 36).Cells were cultured in serum free prostate epithelial cell growth media and identified by immunocytochemical studies.The cells were passaged and cultured in media free of bovine pituitary extract and EGF and TGF-? 1 and EGF in different doses were then added either alone or in combination according to experimental requirement.The rate of cell proliferation was assessed by counting the cell number and by 5-bromo-2'-deoxyuridine (ELISA).Apoptosis induced by TGF-? 1 was examined by in situ transferase-mediated dUTP nick and labeling. Results The cultured cells had the typical morphological features of epithelium and stained positive for PSA and Pan-Keratin.The cells from normal prostates of young donors showed more mitogenic activity than those from BPH prostates.EGF enhanced cell proliferation whereas TGF-? 1 inhibited cell proliferation which could be reversed by increasing concentration of EGF.TGF-? 1 induced apoptosis of human prostatic epithelial cells.The effect of TGF-? 1 and EGF was concentration dependent. Conclusions TGF-? 1 is a direct physiological regulator of cell proliferation and cell apoptosis of human prostatic epithelial cells.

Objective To investigate the effect of TGF ? 1 and EGF on the proliferation of cultured human prostatic epithelial cells. Methods The primary culture was prepared by collagenase digestion of minced prostatic tissue obtained from prostatectomies of 8 benign prostatic hyperplasia(BPH) patients (aged 53 to 70) and 5 organ donors (aged 23 to 36). Cells were cultured in serum free prostatic epithelial cell growth media and identified by immunocytochemical method. The cells were passaged and cultured in media without bovine pituitary extract (BPE) and then, EGF and TGF ? 1 with different concentration were added into the culture either alone or in combination according to the experimental protocol. The cell proliferation was assessed by counting the cell number (BrdU) and ELISA. Results Cultured cells showed typical morphological features of epithelium and stained positive for PSA and Pan Keratin. After 5 7 passages cells went senescence. BPE and EGF enhanced whereas TGF ? 1 inhibited the cell proliferation and the inhibition was reversed by increasing the concentrations of EGF. The effect of both TGF ? 1 and EGF displayed concentration dependent manner. Conclusions Cell proliferation of the cultured human prostatic epithelial cells could be modulated by TGF ? 1 and EGF. These results indicated that TGF ? 1 and EGF, as the negative and positive growth factors might play an important role in the pathogenesis of BPH.

BACKGROUND: Non-adherent mesenchymal stem cells (NA-MSCs) can form colony forming unit of fibroblasts and induce the differentiation into adipocytes, osteoblasts, and chondrocytes. OBJECTIVE: To determine the effect of epithelial growth factor (EGF) on colony formation of fibroblasts and differentiation into neuron-like cells from NA-MSCs.METHODS: Bilateral femur and tibia as well as total MSCs were separated, and repeated-transfer was employed to purify NA-MSCs. The fifth-passage total MSCs and NA-BMCs were induced in a medium containing EGF and basic fibroblast growth factor (b-FGF) for 2 weeks. Colony unit formation of fibroblasts, effect of EGF on colony-forming unit of fibroblasts, and relative protein expression detected by toluidine blue and immunocytochemical staining were observed. RESULTS AND CONCLUSION: Both total MSCs and NA-BMC could generate colony-forming unit of fibroblasts. After treatment of EGF, colony-forming unit of fibroblasts from NA-BMC was increased significantly. Immunocytochemical staining demonstrated that two weeks later both neuro-specific NeuN and NF-200 were observed in total MSCs and NA-BMC; while, toluidine blue staining indicated that neuron-specific Nissl body was observed in some cells. EGF can effectively promote colony-forming unit of fibroblast from NA-BMC, and repeated-transfer NA-BMC can induce differentiation into neuron-like cells.
