Objective To observe the effect of ketamine on apoptosis and synaptophysin expression in 7-day-old infant SD rat hippocampal neural cells. Methods Thirty SD rats of 7 days old were randomly assigned to receive the injection of 25 mg/kg ketamine (K_ 1 group)or 50 mg/kg (K_ 2 group) or 50 ml/kg normal saline (K_ 0 group). In 24 h after injecton, all rats were killed and the synaptophysin was tested by using immunhistochemistry and Western blotting, the apoptosis of neuronal cell by Tunel. Results In 24 h after injection of ketamine,the number of apoptotic neural cells increased,which of K_ 0 group was (5.3?1.7), K_ 1 group (9.5?4.2), K_ 2 group (23.4?7.6), and the grey values of synaptophysin by immunhistochemistry of K_ 0 group was (174.11?4.68), K_ 1 group (181.36?4.17), K_ 2 group (198.25?3.06), and the OD values of synaptophysin piece decreased, which of K_ 0 group (4 007?758), K_ 1 group (2 621?465), K_ 2 group (987?183). Conclusion In 24 h after treatment with ketamine, the expression of synaptophysin was decreased in hippocampl neural cells, the number of apoptotic neuronal cells were increased, which may be involved in neurotoxicity caused by ketamine.

Objective To investigate the preventive effect of health education on prevention of vaginitis among Guangzhou ’ s career women.Methods 479 career women with confirmed diagnosis of vaginitis in 2013 were cured and followed up for 1 year.Pa-tient were divided into Control Group (n=202) and Observation Group (n=277) according to whether accompanied the health edu-cation on prevention of vagnnitis.The recurrence rate of vaginitis during the 1 -year follow -up was compared between the two groups.Results In Control Group, 192 patients (95.05%) finished the follow -up, and in Observation Group, 260 patients (93.86%) finished the follow-up, there was not statistical difference in accomplishment ratio of follow -up (p>0.05).The recur-rence of rate of vaginitis was statistical higher in Control Group (72/192, 37.50%) than that in Observation Group (64/260, 24.62%) (P<0.05).Conclusion Health education could reduce the recurrence rate of vaginitis significantly.

Skeletal muscle has high regenerative capability. It is able to regenerate completely after acute traumatic damage, while the repairing process often accompanied by fibrosis in the chronic degenerative conditions such as muscular dystrophy and repeated muscle fiber damage. Through in-depth study on the mechanisms of skeletal muscle fibrosis in the past decade, it has been found that a variety of cells and regulatory molecules involved in the process, especially muscle satellite cells-derived myofibroblasts, transforming growth factor β (TGF-β) and other fibrosis promoting growth factors. This review focused on the cellular and molecular mechanisms of the skeletal muscle fibrosis and relevant antagonistic strategies.

Objective To compare the clinical effects of treating cervical prolapse of intervertebral disc by using Solis cage, titanium cage and autogenous iliac crest graft (AICG) combined with titanium plate. Methods 64 cases of cervical prolapse of intervertebral disc were analyzed retrospectively. All the patients were followed up for about one year. Group A is composed of 20 patients (30 intervertebral spaces) treated with microdiscectomy and Solis cage fusion;group B is composed of 21 patients(22 intervertebral spaces) treated with titanium cage and group C is involved of 23patients(28 intervertebral spaces) which were dealt with AICG combined with titanium plate. The differences in the to-tal X ray exposure time, time working on iliac bone, incidence of complications, fusion rate, incidence of JOA score recovery rate more than 50 % and rehabilitation time of the three groups are analyzed. Results All indexes from group A and B were more satisfactory than those from group C (P＜0. 05). The statistic analysis results of the incidence of complications of cervical part, rehabilitation time in group A are 5.0± 1.8, 5.1 ± 1.2; and that is 14.3±2.6, 7.5 ± 1.6and 26.1±6.2, 8.6±2.3 in group B and group C respectively. There is significant difference between group A and group B on the incidence of complications of cervical part and rehabilitation time (P＜0.05). Results of the incidence of JOA score recovery rate ＞ 50 % in group A(95.8 ± 3.2) was more satisfactory than that in group B(93.6 ± 2.9),while there was no statistical difference between group A and group B (P＞0.05). Conclusion The Solis cage is better in treating the cervical prolapse of intervertebral disc than other ways. Also, it makes the operation easier, rehabilitation time shorter, and it causes fewer complications.

Objective To analyze the factors associated with the outcome of pyeloplasty in term of renal function and morphology improvement in children with unilateral ureteropelvic junction obstruction,in order to provide clinical evidence for the treatment of hydronephrosis in children.Methods Clinical data of 174 children who underwent unilateral dismembered pyeloplasty from January 2009 to June 2014 were retrospectively studied.Differential changes in renal function and renal morphology after pyeloplasty were assessed by serial renal scan and ultrasound.On the basis of preoperative split DRF,these patients were divided into three groups:group Ⅰ with DRF ≥40％ (n =99),group Ⅱ with DRF 30％-40％ (n =29) and group Ⅲwith DRF ＜ 30％ (n =46).According to their age at surgery,the children were divided into four groups,including group A aged 1-3 months (n =52),group B aged 3 months-3 years (n =44),groupCaged3-6years (n =37),and group D aged more than 6 years (n =41).Results Inall 174 children,postoperative complication occurred in 7 cases,including urinary tract infection in 6 cases and renal atrophy in 1 case.A significant improvement of both function and morphology was confirmed in most patients (P ＜ 0.01).Patients in group Ⅰ showed stable renal function after operation(DRF 48.46％ ±4.80％ vs.50.78％ ± 5.45％,P ＜ 0.01),of them who underwent pyeloplasty at 1-3 months of age showed the best obvious recovery of renal morphology.Renal function of patients in group Ⅱ recovered obviously and most of them reached to the initial values (DRF 35.18％ ± 2.95％ vs.43.91％ ± 6.89％,P ＜ 0.01).While renal function of patients in group Ⅲ recovered significantly after surgery,most of them failed to restore the initial values(DRF 20.70％ ± 6.90％ vs.33.78％ ± 12.49％,P ＜ 0.01),and among them,the aged 1-3 months group possessed the best recovery.Moreover,the morphological improvement was similar to the functional improvement.The time for hydronephrosis recovered to less than Grade 2 of Society for Fetal Urology(SFU)was 6,24 and over 24 months respectively in group Ⅰ,Ⅱ and Ⅲll,and the renal morphology gradually improved with the increasing duration of follow-up.Conclusions The renal function and morphology of most patients improved significantly after pyeloplasty.Recovery of renal function and morphology after surgery was significantly correlated with the preoperative DRF.Early surgical intervention may improve the function and morphology recovery of the involved renal unit.

Objective To explore the inhibitory effect of pulsed ultrasound on skeletal muscle fibrosis after injury.Methods Thirty elderly male rats with gastrocnemius muscle injury were divided into an ultrasound group (UG) and a control group (CG) using a random number table.The injured muscles in the UG were treated using pulsed ultrasound (frequency 1 MHz,average strength 40 mW/cm2,duty cycle 20％) for 10 min daily from day 3 after the injury.The CG was given no treatment.On days 3,7,14,21 and 28 after the injury,histological and immunohistochemical analyses of the gastrocnemius muscles of both groups were performed.Results The collagen fiber mean optical density of the muscles increased gradually after the injury and reached its peak on day 21.It was significantly lower in the UG than in the CG on each test day.The expression of α-SMA increased gradually after the injury,but it too remained significantly lower in UG than that in CG.Conclusion Pulsed ultrasound may reduce collagen formation and α-SMA expression in injured skeletal muscle,and then inhibit muscle fibrosis.
