ObjectiveTo investigate the change of Bcl-2 and P53 expresssion after whiter matter damage in neonatal rats. Methods100 rats (2 days old) were randomly divided into two groups: control group and periventricular leucumalacia (PVL) group. Control group received normal saline 5 mg/kg intraperitoneal injection, PVL group received lipopolysaccharide (LPS) 5 mg/kg intraperitoneal injection. The expression of Bcl-2 and P53 was measured 6 h, 12 h, 24 h, 48 h after operation with immunohistochemical staining. ResultsThe expression of Bcl-2 increased 6 h after operation, and to the top 48 h after operation in the PVL group, which was significantly different compared with the control group (P<0.01). The expression of P53 increased at 6 h after operation, and to the top 12 h after operation in the PVL group, which was significantly different compared with the control group (P<0.01). ConclusionThe expression of Bcl-2 and P53 increased in the white matter injuried neonatal rats induced by LPS.

Objective To assess and compare physical and chemical properties of skin among different body areas of healthy children at different ages from Beijing.Methods A total of 116 healthy children were recruited from Beijing,China,and classified into four age groups.Tewameter TM300 was used to measure transepidermal water loss (TEWL) value,Corneometer CM825 to estimate stratum corneum hydration,and skinpH-Meter PH905 to determine skin surface pH,in the forehead,cheek and forearm.The Mexameter MX 18 probe to determine melanin index of the face.Analysis of variance was carried out to assess differences in these parameters among different measurement sites and age groups.Results TEWL value did not differ among different age groups or measurement sites (both P ＞ 0.05).The stratum corneum hydration value of forehead,cheek and forearm was 51.53 ± 15.70,39.88 ± 10.48 and 50.33 ± 17.54 respectively in the age group ＜ 1 year,49.95 ± 17.88,32.51 ± 12.09 and 36.10 ± 7.43 respectively in the age group 1-3 years,51.37 ± 10.60,31.65 ± 9.01 and 34.41 ± 8.21 respectively in the age group 4-6 years,49.74 ± 10.64,39.99 ± 50.43 and 29.35 ± 8.10respectively in the age group 7-12 years,with significant differences among different measurement sites (P ＜ 0.05) but not between different age groups (P ＞ 0.05).The cheek and forearm showed lower stratum corneum hydration value than the forehead.No statistical difference was observed in pH value at the same measurement sites between the age group ＜ 1 year (forehead 5.27 ± 0.60,cheek 6.12 ± 0.51 and forearm 5.48 ± 0.45),1-3years (forehead 4.68 ± 0.58,cheek 6.80 ± 0.55 and forearm 5.07 ± 0.58),4-6 years (forehead 4.58 ± 0.37,cheek 5.70 ± 0.48 and forearm 5.09 ± 0.49),and 7-12 years (forehead 4.87 ± 0.51,cheek 5.72 ± 0.49 and forearm 5.09 ± 0.51),but the cheek had significantly higher pH value than the forearm and forehead (both P ＜ 0.05).Melanin value on the face did not differ between different age groups (P ＞ 0.05).Conclusion Physical and chemical properties of skin vary with body sites in healthy children.

Objective To investigate the clinical diagnostic value of transperineal ultrasound in women in late pregnancy with stress urinary inconti?nence. Method Totally 66 cases of women in late pregnancy were selected,who did not suffer from SUI(groupⅠ),and 54 cases of women in late pregnancy who suffered from SUI(groupⅡ). Another 63 cases of healthy childless women were used as normal control(groupⅢ). Transperineal ultrasound was used to dynamically observe their pelvic floor structure,and the ultrasonic parameters were recorded and analyzed,including the posi?tion of bladder neck in X axis and Y axis((Djx,Dzx,Djy,Dzy)during resting period and tension period,the vesicourethral angle(αj,αz),the Bladder angle(βj,βz). The moving of the bladder neck in X axis(ΔDx=Dzx-Djx)and Y axis(ΔDy=Dzy-Djy),as well as the bladder rotation an?gle(Δβ=βz-βj)were calculated and the movement of the bladder neck(ΔD)was measured,followed by comparative analysis. The threshold val?ues of all ultrasonic parameters were determined by the ROC curve analysis. Results The bladder neck of all three groups were backward during tension period. Compared with groupⅢ,ΔDy,Djx,Dzx obviously decreased in groupⅠand groupⅡ,whileβj,βz,αj increased significantly.ΔDx of groupⅡwas significantly larger than that of groupⅢ(P<0.05);There was significant difference in Djy,Dzy,ΔD,Δβandαz among the three groups(P<0.05);In ROC curve analysis,when the critical value of Djy,Dzy,ΔDy,ΔD,αz andΔβwas-1.75 cm,-1.71 cm,0.25 cm,0.29 cm,131.5° and 3.5° ,their sensitivity was 88.9%,88.9%,72.2%,83.3%,88.9%and 72.2%,and the specificity was 72.2%,81.8%,72.7%, 95.5%,86.3%and 68.2%,respectively. Conclusions The transperineal ultrasound could clearly show the pelvic floor of the women in late preg?nancy,the bladder urethral support structure damage or defect was more serious in the women in late pregnancy who were suffering from SUI,and the determination of the critical values of all ultrasonic parameters helped the screening of SUI in women in late pregnancy.

OBJECTIVE To avoid the hospital(infection) in the dental surgery operating room.METHODS The(international) ISO quality standard was applied to establish the quality control the hospital infection.RESULTS The quality control for the hospital infection was guaranteed in the dental surgery operating room,and the items (observed) were in the allowance of the legislations for the hospital infection.Zero case of hospital infection(happened.) CONCLUSIONS It is useful for the hospital infection administration in the dental surgery operating room to apply the international ISO quality standard.

Hypertension is one of the high prevalence diseases in Xinjiang,which severely affect the body-mind heath of the people.In Northwest area,particularly in xinjiang,dryness syndrome is prevailed owing to environmental factor.Therefore,dryness syndrome of climacteric hypertension in xinjiang is more prevalent than that in other areas.Discussion on the effect of environmental factors on climacteric hypertension is a main aspect of Northwest dryness syndrome study.It may provide reliable and helpful basis of prevention and treatment of climacteric hypertension in xinjiang.

Objective:To evaluate the results of 25 cases of cervical spondylotic myelopathy treated by the bilateral backward displacement of lamina and expansion of the nerve root canalsince 1994. Method: Thepostopera tire and preoperative CT and MR imaging were used to compare the efficacy of backward displacement and decompression of the spinal cord. Result: According to the criteria for assessment set up by Dr Yin Huafu, the result was excellent in 13 cases, good in 8 and acceptable in 3; one case failed to get any improvement. Conclusion: This operation is a safe and an effective procedure for the treatment of the majority cases of cervical spondylotic myelopathy. In some cases this procedure should be done in combination with anterolateral decompression.
