Objective To analyse and understand the main reasons for cesarean section,in order to reduce the rate of cesarean section. Methods Clinical analysis was performed in 6781 patients who underwent cesarean section from January 2004 to December 2008. Results ①Cesarean section rate was increasing from 2004 to 2008, which was 32. 00% (840/2625) , 35. 00% (966/2760) , 39. 08% (1186/3035), 45. 98% (1669/3630) and 51. 88% (2120/4086) .respectively. Compared to 2004, the cesarean section rate in 2008 increased significantly (P <0.01). ②The proportion of the main cesarean section indications changed, the proportion of social factors ,fetal factors and maternal factors were increasing gradually. Cephatopelvic disproportion in 2008 decreased significantly compared to that in 2004(x2 = 194. 805 ,P <0. 01). There was significent difference in each indication from 2004 to 2008. Conclusions The cesarean section rate has increased due to medical reasons and social reasons. To ensure the safety of the mothers and children, vaginal delivery should be adopted as far as possible. The cesarean section without medical indication should be prohibited.

OBJECTIVETo compare the differences in the efficacy on lower limb motor function in children with spastic cerebral palsy between the combined therapeutic program of Jin three-needle therapy and MOTOmed intelligent motor training and the simple MOTOmed.

METHODSEighty children with spastic cerebral palsy were randomized into an observation group and a control group, 40 cases in each group. In the observation group, Jin three-needle therapy was used at four mind points, three brain points, three intelligent points, three temporal points, three knee points and three foot points, as well as Chengjin (BL 56), Chengshen (BL 57) and the other. Additionally, MOTOmed was given in assistance with conventional rehabilitation training. In the control group, MOTOmed and the conventional rehabilitation training were adopted. In the two groups, the treatment was given once a day, 20 treatments made one session and there were 3 to 5 days at interval between the two sessions. The efficacy evaluation was performed after continuous 3 sessions of treatment. The gross motor function measure (GMFM) and modified Ashworth scale (MAS) were applied for the evaluation before and after treatment in the two groups.

RESULTSAfter 3 sessions of treatment, GMFM score was increased apparently as compared with that before treatment in the two groups (P < 0.01, P < 0.05). After treatment, GMFM score in the observation group was increased more remarkably than that in the control group (55.32 +/- 17.10 vs 47.48 +/- 17.18, P < 0.05). After treatment, the total effective rate of gastrocnemius Ashworth spasm grade [90.0% (36/40)] in the observation group was better apparently than [72.5% (29/40)] in the control group (P < 0.05).

CONCLUSIONThe combined therapeutic program of Jin three-needle therapy and MOTOmet intelligent motor training improves the lower limb motor function of the children with spastic cerebral palsy and its efficacy is better than simple MOTOmed.

Background In vitro study showed that chemotaxis consist of chemotaxis factor 4(CXCR4)and stromal cells derived factor-1(SDF-1)and may play a role in the orientation and migration of retinal progenitor cells (RPCs)toward lesion.Overexpression of CXCR4 in RPCs can enhance the chemotaxis activity.Objective This work was to explore the feasibility and underlying mechanism of up-regulation of CXCR4 on RPCs induced by hypoxia.Methods RPCs were retained in an incubator with normal O2volume(16％)or hypoxia condition(10％ O2)for 12 hours and 24 hours respectively.Flow cytometer cell analysis screening(FACS)was conduced to measure the proportion of CXCR4-expressing cells,and CXCR4,HIF-1 mRNA were analyzed by reverse transcription-polymerse chain reaction(RT-PCR).The chemotical effect of 30 mg/L SDF-1 to RPCs cultured under the hypoxia condition was assessed using Boyden chamber.Results The expression level of CXCR4(CXCR4 mRNA/β-actin mRNA)inRPCs cultured by 10％ O2 for 12 and 24 hours were 0.28+0.07and 0.48+0.17 and increased by 1.75 and 3.00 fold more than that of 16％ O2 culture group(0.16+0.02)(P＜0.01).The expression level of HIF-1 mRNA(HIF-1 mRNA/β-actin mRNA)in RPCs cultured by 10％ O2 for 12 and 24 hours were 0.18 ±0.07and 0.38 ±0.13 and increased by 3.00 and 6.30 fold more than that of 16％ O2 culture group(0.06±0.01)(P＜0.01).The chemotical effect of 30 μg/L SDF-1 to RPCs increased from 13.00％ in 16％ O2 culture group to 36.00％ and 46.00％ in the cells cultured by 10％ O2for 12 and 24 hours.FACS revealed that the proportion of CXCR4+ cells in hypoxia-exposure for 12 and 24 hours were 26.90％ and 46.10％,respectively,but that in 16％ O2 culture group was 9.10％,showing a statistically significant difference(P ＜ 0.01).Conclusions RPCs induced by hypoxia can enhance the expression of CXCR4 in RPE cells and the chemotaxia to SDF-1.The overexpression of H1F-1 in RPCs may be involved in the up-regulation of CXCR4 expression.

Objective To retrospectively investigate and compare the clinical features in type 2 diabetic patients with various lesions of diabetic nephropathy.Methods One hundred and fifty patients of type 2 diabetes mellitus were registered from December 1990 to April 2004,among them 73 cases of diffuse glomerulosclerosis (DIF)and 77 nodular glomerulosclerosis(NOD)were all proven by renal biopsy.Data such as the durations of diabetes mellitus and hypertension,body mass index(BMI),diabetic retinopathy,HbA_1c,plasma albumin, proteinuria,urine N-acetyl-?,-glucosaminidase,urine osmolarity,ereatinine clearance rate(Ccr)were collected and compared.Results(1)Compared with the patients with DIF,the patients with NOD had longer duration of diabetes mellitus[(122.0?8.1 vs 56.0?7.8)months,P

Objective To evaluate the effects of mild hypothermia therapy on cerebral function and edema as assessed by magnetic resonance imaging (MRI ) during the first 72 hours after restoration of spontaneous circulation (ROSC)in a porcine model.Methods Ventricular fibrillation was induced in 33 Inbred Wuzhishan miniature swine.After ventricular fibrillation untreated for 8 min,standard CPR was initiated and 30 animals got ROSC.The ROSC animals were randomly (random number)assigned to normothermia group (n=15 ) and hypothermia group (n =15 ).The hypothermia group immediately received endovascular cooling to regulate temperature to 33 ℃,which was maintained for 12 h,followed by passive rewarming at 0.5 ℃/h to 37 ℃.The two groups were scanned to get Diffusion-weighted imaging (DWI)at baseline (before experiment),6 h,12 h,24 h,and 72 h after ROSC.The statistical analysis was carried out with Student t test,One-way repeated-measures and Kaplan-Meier survival analysis.Results Compared with the normothermia group,the hypothermia group exhibited a higher 72-h survival rate (73.3% vs.40%,P<0.05),lower neurological deficit scores (43.81 vs.119.50;P<0.01),a lesser decrease in the apparent diffusion coefficient during DWI and milder cerebral edema on DWI image. Conclusions Cerebral edema occurred at early stage after ROSC.Cerebral edema was worst at 6 hours after ROSC and then subsided gradually.Hypothermia therapy could reduce cerebral edema and produce a protective effect on neurological function.MRI could effectively reflect the underlying trend of cerebral injury of swine within the first 72 h after ROSC,and demonstrated that hypothermia could reduce brain edema, increase cerebral blood flow,and reduce the production of toxic metabolites.DWI could monitor brain injury after resuscitation and could be used to evaluate the efficacy of hypothermia intervention dynamically.

Objective To observe effect of lidocaine pretreatment to malondialdehyde(MDA) and endothelin(ET) of patient ac-cepeted brain tumor removing and discuss the optimized pretreatment time .Methods 60 brain tumor patients in the hospital from March 2009 to September 2011 .according to the different pretreatment time ,the patients were randomly divided into five groups :group A(preoperative 48 h) ,group B(preoperative 24 h) ,group C(preoperative 12 h) ,group D(0 h or anesthesia induced) ,group E (control group) and group F(blank control group) ,10 cases in each group .Group A ,B ,C ,D with 1% lidocaine 1 .5 mg/kg intrave-nous pretreatment on schedule ,then induced conventional anesthesia ;group E were supplemented with 1% lidocaine 2 .5 mg · kg -1 · h-1 intravenous injection after anesthesia induction ;group F was performed routine program without lidocaine .The spontaneous breathing time ,awake time and tracheal extubation time was recorded ,while NIHSS score for evaluation of neural function defect was applied ,and peripheral serum level of MDA and ET was detected by colorimetric technique and radio-immunity .Results In group C ,the spontaneous breathing time ,awake time and tracheal extubation time were shorter than other groups ,but the difference had no statistically significant(P>0 .05) .There was no significant difference among each group in the aspect of NIHSS score 1 day before surgery(P>0 .05) ,after 14 days of operation ,NIHSS of group C was statistically lower than that of group E and group F (P<0 .05) .Before anesthesia induction ,there was no significant difference among groups (P> 0 .05) .MDA and ET content in group C was significantly lower than those in other groups after surgery (P<0 .05) .Conclusion Lidocaine given 12 h before cere-bral ischemia has varying degree protection against cerebral ischemia-reperfusion injury .The protection has relation with the de-crease of MDA and ET content .

Objective To analyze the changes and clinical significance of live function in advanced non-small cell lung cancer after chemotherapy.Methods The data of 164 patients histopathologically confirmed as advanced nonsmall cell lung cancer with complete medical history data from January 2007 to September 2010 were retrospectively analyzed.All the patients received chemotherapy by docetaxel or gemcitabine plus nedaplatin,regular liver function hematological monitoring and liver color ultrasound examination,which revealed the changes of liver function and liver morphology.Results Docetaxel or gemcitabine plus nedaplatin could induce liver function indexes abnormality in patients with advanced nonsmall cell lung cancer.The main symptoms were the rise of ALT,AST with different extent (ALT:29 U/L vs 30 U/L,AST:54 U/L vs 39 U/L,P ＜ 0.05),which were not related with the sex,age,tumor pathologic types and the clinical stages (P ＞ 0.05).Patients received chemotherapy by gemcitabine were inclined to experience liver function indexes abnormality (P ＜ 0.05).Patients with hepatic metastases and hepatitis B surface antigen positive before chemotherapy were inclined to experience liver function indexes abnormality (P ＜ 0.05).The ALP,γ-GT,TBL,ALB levels after treatment were almost the same as those before treatment (P ＞ 0.05).Conclusions Taking docetaxel or gemcitabine plus nedaplatin could induce liver function indexes abnormality in patients with advanced nonsmall cell lung cancer.Patients treated by chemotherapy complicated with hepatic metastases,hepatitis B surface antigen positive and treatment by gemcitabine were inclined to experience liver function indexes abnormality,which is value to research.
