Objective To investigate the ureteral injury in gynecological laparoscopies and discuss its diagnosis,treatment and prevention.Methods Six cases of ureteral injury were reviewed.The clinical features including the type of diseases,uterine size,pelvic adhesion and the methods of diagnosis,treatment were studied.Results Ureteral injuries happened during laparoscopically assisted vaginal hysterectomy(LAVH). The gynecological disorders included pelvic adhesions,endometriosis and leiomyoma in cervical.Patients presented flank pain,fever,increased volumes discharge.Conclusion Ureteral injury is an uncommon and sever complication in gynecological laparoscopies.Fever,flank pain and abnormal vaginal discharge should be paid attention to be ureteral injury.

ObjectiveTo investigate the feasibility of apphcation of risk factors management in nursing of the fever outpatient.Methods145 patients from May to December 2009 admitted to fever clinic was defined as the control group, 157 patients from January to May 2010 admitted to fever clinic were set as the observation group. The control group was given routine nursing, while the observation group adopted risk factor management measures. The management indices of the two groups were compared.ResultsThe patients' recognition score of risk factors of fever clinic was (85.4 ± 2.7)in the observation group, higher than(73.2 ± 3.9)in the control group. Patients' satisfaction degree was 84.7％ in the observation group, higher than 67.6％ in the control group. Rate of risk event of the observation group was 1.3％, lower than 6.2％ in the control group, the incidence of nursing errors was 0.6％ in the observation group, lower than 4.1％ in the control group, rate of patients' complaints of nurses was 1.3％ in the observation group, lower than 5.5％ in the control group.ConclusionsThe implementation of risk factors management in fever clinics can reduce medical accidents, improve nursing quality, so this clinical management mode deserves promotion and application.

Objective To investigate the effect of nursing intervention on preventing leakage of urine in patients with indwelling catheter in neurology department.Methods A total of 76 patients with indwelling catheter in neurology department were randomly assigned into the observation group and the control group with 38 cases in each group.The control group received routine care,the observation group received systemic nursing intervention on the basis of routine care.The incidence of leakage of urine and patients satisfaction degree with nursing service was observed between two groups.Results The incidence of leakage of urine in the control group was 21.1％,higher than 2.6％ of the observation group.he score of satisfaction degree of the observation group was (4.66±0.62),higher than(3.26±0.42) of the control group.Conclusions Nursing intervention can effectively reduce the incidence of leakage of urine and improve the satisfaction degree of patients with indwelling catheter in neurology department,it is worthy of clinical application.

Objective To investigate the epidemiology and clinical features of epidemic cerebrospinal meningitis of children in Shanghai area in the last 2.5 years. Methods A retrospective study was conducted in 27 hospitalized patients with epidemic cerebrospinal meningitis by analyzing the clinical manifestation,epidemiology and laboratory test fingdings from Jan.2006 to Jun.2008.Statistical analysis of the clinical manifestations of cases in serogroup A,B and C was performed according to Neisseria meningitidis infection. Results There were sporadic cases of children with epidemic cerebrospinal meningitis in Shanghai area in the last 2.5 years.The seasonal distribution illustrated the peak occurrence from Feb.to Apr.Among all these cases,92.6% were floating children.Common types(74.1%) were the predominant clinical manifestations and the others were fulminate types(25.9%).Four cases in each of serogroup A and B,and 8 cases of serogroup C were identified by serotyping on 14 Neisseria meningitidis strains and genotyping on the other 2 cases′ cerebrospinal fluid specimens.All the patients in serogroup A with meningococcal diseases were not vaccinated before and 25.0% of them belonged to fulminate types.Half of the cases had petechia on the skin and the prevalence of skin necrosis was 25.0% and 50% had complications of nervous system.No fulminate type was present in cases of serogroup B meningococcal disease and only 1 case had slight petechia on the skin.However,intensive convulsions occurred in 75.0% of the patients,and all of them had complication of nervous system,with a few had sequela.Among the patients in serogroup C meningococcal disease,62.5% patients were vaccinated with serogroup A Neisseria meningitidis.In serogroup C,Neisseria meningitidis infection was found in each age group,with petechia on skin,skin necrosis,immunity correlation fever and complications of nervous system in 87.5%,50.0%,75.0% and 12.5% of the patients,respectively. Conclusions 1.Epidemic cerebrospinal meningitis occurred sporadically in children in Shanghai area,the majority of patients were floating populations.2.Clinical manifestation was typical in patients of serogroup A meningococcal disease.Subdural effusion or ventricalitis was more common in patients of serogroup B meningococcal disease.In serogroup C,Neisseria meningitidis was the most prevalent serotype leading to epidemic cerebrospinal meningitis.More cases were found in patients infected with serogroup C,Neisseria meningitidis with severe shock and immunity correlation fever compared with the other groups.Prophylactic vaccination of serogroup C polyvalent meningococcal organism should be recommended.

Objective To study the effect of H_2O_2 on the cultured melanocytes and the relationship between oxidative stress and vitiligo.Method Melanocytes were cultured with H_2O_2,the proliferation and melanogenesis of melanocyte were analysed by MTT and NaOH assay.Result H_2O_2 can inhibite the proliferation and melanogenesis of melanocytes,and the inhibition was concentration and-time-dependent.Conclusion Oxidative stress can inhibite the proliferation and melanogenesis of melanocytes,but oxidative damage can not induce vitiligo.

Objective To investigate the effects of short-segment pedicle screws system on type A thoracic and lumbar spine fracture with or without pedicle screws on the fractured level. Methods 23 patients with type A thoracic and lumbar spine fracture were included, in which 11 cases received traditional short-segment pedicle screws system without pedicle screws on the fractured level (group A), and other 12 cases with pedicle screws on the fractured level (group B). The anterior vertebral height, posterior vertebral height and local kyphosis an-gle were measured before and after operation. Results All pedicle screws were successfully implanted with good location and stability. The vertebral height and kyphosis angle significantly improved after operation in both groups (P<0.05), and the improvement of kyphosis angle was more in group B than in group A (P<0.05). Conclusion Short-segment pedicle screws system with pedicle screws on the fractured level may fine correct the kyphosis angle in short term.

AIM: To study the physiological function changes of the tears film after rebuilding ocular surface with corneal stem cells, and to discuss the validity and the estimate system of rebuilding ocular surface with the corneal stem cells. METHODS: The male New Zealand rabbits were used to establish the alkali burning model in the right eye. The corneal stem cells of the left eye were cultured on the amniotic membrane in vivo, and then transplanted to the right eye. Furthermore, the physiological function changes of the tear film were examined. RESULTS: Compared to the before alkali burning, the ocular surface cell morphology was similar after rebuilding ocular surface with the corneal stem cells, which were cultured on the amniotic membrane in vivo; The tear film breakup time test showed the a remarkable difference between after and before the alkali burning, but the cell modality after rebuilding had no remarkable difference compared to that before the alkali burning. CONCLUSIONS: It's an effective method to rebuild the ocular surface with the corneal stem cells in vivo, the cell framework and the physiological function of the tears film recover well after rebuilding. It may be a validity estimate system of rebuilding ocular surface to analyze framework and configuration of the ocular surface and test the tear film breakup time.
