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 observe the changes of serum complements and proinflammatory cytokines in rats with sepsis, and to explore the possible mechanism.Methods 120 healthy male Wistar rats were randomly divided into three groups: normal control group (n = 15), sham operation group (n = 15) and sepsis group [cecum ligation and puncture (CLP) operation,n = 90]. The sepsis rats were sacrificed on 24, 48 and 72 hours after modeling. The level of serum complements (C5, C5a) and cytokines tumor necrosis factor-α (TNF-α), interleukin (IL-1, IL-6), high mobility group box 1 (HMGB1), macrophage migration inhibitory factor (MIF) were detected by enzyme linked immunosorbent assay (ELISA).Results Compared with normal control group and sham operation group, the levels of serum complements C5, C5a and IL-1β were significantly increased at 24 hours after CLP in sepsis group [C5 (ng/L): 1.60±0.19 vs. 1.04±0.20, 1.09±0.09; C5a (ng/L): 0.20±0.02 vs. 0.18±0.01, 0.18±0.02; IL-1β (ng/L): 700.20±111.41 vs. 475.87±108.96, 592.29±121.57; allP < 0.05]; then the levels of C5, C5a and IL-1β declined, the level of serum C5 were also higher than normal control group at 48 hours and 72 hours after CLP (ng/L: 1.17±0.24, 1.27±0.24 vs. 1.04±0.20, bothP < 0.05). In sepsis group the level of serum TNF-α (ng/L: 51.33±1.96, 51.06±1.64) was lower than that in normal control group (59.53±3.06) and sham operation group (57.91±2.72) at 48 hours and 72 hours (allP < 0.05). There was a time dependent rise of serum HMGB1 in sepsis group, which level was much higher than that in normal control group and sham operation group at 72 hours after CLP (ng/L: 472.21±20.94 vs. 406.00±43.16, 404.41±35.39, bothP < 0.05). There were no significant differences of MIF, and IL-6 level between groups at each time points.Conclusions Complement system led to uncontrolled inflammatory response and immune dysfunction through the release of proinflammatory cytokines and inflammatory mediators, which maybe one of the important mechanism of the pathology of sepsis.

Objective To explore a new model of medical humanity education in new situation. Methods Extensive survey was carried out among medical students,and discussion and consultation were hold to faculty and education administers.A new teaching model was established. Results A curriculum system with 1 or 2 core courses supported by some elective courses and social practice is under the process of implementation and achieved preliminary success.Conclusion The medical humanity education should pay attention to the development of connotation instead of pursuing the extension of quantity blindly,which means that students' school work must be eased by focusing on self-study and self-education.Medical students'life path with high-minded personality training should be strengthened.

Objective To explore the clinical characteristics and treatment of nodular panniculitis disease in children. Methods Clinical data of 13 cases with nodular panniculitis disease were reviewed retrospectively. Their etiology,clinical manifestation,misdiagnosis cause,pathologic characteristics, treatment and outcome were analyzed. Results Its clinical manifestation was multiform and showed mainly as fever and hypodermic nodule. Concomitant damages to digestive, respiratory, circulatory and renal system might occur in those children with the system type of this disorder. Conclusion Pediatric nodular panniculitis disease can be easily misdiagnosed and lack of specificity in the early stage, and complicates multiple organs damage.
