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 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.

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

Background Interleukin-17 (IL-17)is a potent pro-inflammatory cytokine and plays a pathogenic role in autoimmune disease.It was confirmed that IL-17 is implicated in allograft rejection of many transplanted organs.Recent studies have foensed on the effect of IL-17 antagonists on allograft rejection.Objective This study aimed to investigate the inhibitory effect of anti-mouse IL-17 monoclonal antibody (mAb) on corneal allograft rejection.Methods Twenty-five 8 to 10-week-old C57BL/6 mice and 50 BALB/c mice were collected.Donor cornea grafts with 2 mm diameter from 25 C57BL/6 mice was transplanted to 50 eye of BALB/c mice to establish a model of corneal transplantation.The recipients were randomized into 2 groups,and neutralizing mouse IL-17antibody or isotype control antibody was intraperitoneally injected immediately after transplantation for experimental treatment,respectively.Allografts were scored clinically at appropriate time points after treatment based on Plskova criteria,and ≥5 was confirmed as rejection.Infiltrating cells in corneal graft were detected qualitatively and quantitatively by immunohistochemistry and reverse transcription-PCR separately.The cytokine levels of T helper type 1 (Th1),Th2,and Th17 in recipients' spleen wer(c) analyzcd by ELISA.The use of the animals followed the Statement of ARVO.Results Compared with the isotype control antibody group,the survival of grafts was improved in the IL-17mAb group(P＜0.05).The levels of neutrophile granulocyte mRNA,CD4+ and CD8+ T lymphotes mRNA were 2.22±0.10,1.64±0.04 and 1.32±0.10 in the IL-17 mAb group,showing a significant decline in comparison with those of the isotype control antibody group(3.61 ±0.08,2.69±0.06 and 2.17±0.04) (P=0.000,0.000,0.000).Interferon-γ(IFN-γ),IL-12 p40 and IL-17 concentrations in recipients ' splenocytes were (529.80 ± 13.83) ng/L,(539.58 ±10.74) ng/L and(173.70±8.11)ng/L in the IL-17 mAb group,and thosc in the isotype control antibody group were (741.48± 10.51) ng/L,(1156.90 ± 69.93) ng/L and (366.13± 7.93) ng/L,with significant differences between them (P=0.000,0.001,0.000).Conclusions Neutralization IL-17 bioactivity inhibits mouse corneal allograft rejection to a certain extent.

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.

Reflux esophagitis is a common type of gastroesophageal reflux disease.Its pathogenesis is not completely clear,but the body immunity,oxidative stress and chemical damage have gradually become the research focus.According to the latest research, the expressions of related proteins in reflux esophagitis provide a foundation for its pathogenesis. And some kinds of proteins can be used as monitoring index in the development process from reflux esophagitis to esophageal adenocarcinoma. This article is to review the expression and significance of proteins in reflux esophagitis in recent years.
