Objective To observe the treatment of continuous passive motion(CPM) on talipes valgus in the chil-dren with cerebral palsy. Methods There were 57 children in this research including normal group and valgus group, the children in valgus group were randomly divided into control group, non-CPM group and CPM group. The control group didn’t receive any rehabilitation treatment. The non-CPM group received conventional rehabilita-tion treatment. The CPM group received conventional rehabilitation and CPM therapy. Evaluate the children in nor-mal group with plantar pressure analysis and evaluate each patient before treatment two and four months after treat-ment with plantar pressure analysis. Results Compared with the normal group, the percentage of medial midfoot (MMF) pressure, HEEL pressure, initial contact phase(ICP) and forefoot contact phase(FFCP) were obviously higher in valgus groups. On the other hand, the percentage of lateral forefoot ( LFF) pressure, lateral midfoot (LMF) pressure and foot flat phase(FFP) were obviously lower in valgus groups(P < 0. 05). The percentage of MMF pressure, and FFP became lower after treatment in both CPM group and non-CPM group while the percentage of ICP and FFCP became higher(P < 0. 05). In CPM group there was a more obvious change with the percentage of MMF pressure, ICP and FFCP compared with non-CPM group and the control group(P < 0. 05). Conclusion U-sing CPM can alleviate muscle spasms and contracture, correct the deformity of midfoot, enhance the muscle group coordination on foot and further more improve gait of patients with cerebral palsy.

An online questionnaire to 103 professionals of traditional Chinese medicine (TCM) was conducted to acquire their recognition and understanding of international communicative competence. The results showed that foreign language communicative competence and solid medical knowledge are considered the most important qualities while the importance of global vision, strategic thinking, cross-cultural awareness/sensitivity and communicative strategy is comparatively underestimated. It was proposed that domestic TCM universities and colleges strive to improve the soft skills for TCM professionals and cultivate more interdisciplinary TCM talents armed with professional expertise, foreign language communicative competence as well as international and multicultural awareness.

Objective To investigate the levels of inflammatory cytokines in children with low absolute lymphocyte count (ALC).Methods 56 patients with low ALC as the patients group and 20 children with healthy physical examination as the control group were enrolled.Several inflammatory cytokines,namely IL-1,IL-6,IL-8 and TNF-βwere measured with enzyme linked immu-nosorbent assay(ELISA)kits.High sensitive C reactive protein(Hs-CRP)was measured by the immunoturbidimetry(ITM)kit with the automatic biochemical analyzer.Results The concentrations of IL-1,IL-6,IL-8 and TNF-βin the patients were(0.096±0.012) ng/mL,(0.118±0.026)ng/mL,(0.388 ±0.069)ng/mL and(1.256 ±0.245 )ng/mL respectively,which had no statistical differ-ences as compared with the control group(P >0.05);the concentration of HsCRP in the patients group was(5.7±2.8)mg/L,while which in the control group was(4.8±2.6)mg/L,showing no statistically significant difference between them(P >0.05).Conclusion The levels of the cytokines in low ALC patients are not increased,which may be related with the other factors.Actively using tra-ditional Chinese medicine treatment is beneficial to the recovery of disease.

radical resection of colorectal cancer is exact and feasible for evaluating nutritional status of patients and guiding enteral nutritional support therapy.Patients should select nutritional support therapy after operation if there is nutritional risk.The proper nutritional support therapy can improve the postoperative nutritional status of patients with colorectal cancer, enhance the postoperative recovery and reduce the duration of hospital stay.

Objective To investigate the clinical correlation of intestinal bacterial translocation(BT) and in-testinal barrier of pediatric intestinal surgery,and to observe the relationship between BT and postoperative infection.Methods The plasma D-lactic acid,LPS level of 61 children with intestinal surgery in our hospital were detected before and after surgery.Polymerase chain reaction (PCR) was used to test blood bacterial DNA,in order to judge whether there is BT.Results The PCR results of preoperative children were negative,the PCR positive for 3 cases.According to the PCR results,postoperative systemic inflammatory response syndrome(SIRS) and complications of infection of PCR positive group were obviously higher than those of PCR negative group(P ＜ 0.01).And plasma D-lactic acid,LPS inspection of PCR positive group were obviously higher than PCR negative group(P ＜ 0.01).Conclusion Intestinal barrier damage has close relationship with BT in children after intestinal surgery,SIRS and infection complications also has a direct relationship with BT.

Objective To investigate the effects of angiotensinⅡ (AngⅡ) on the Apelin mRNA and APJ mRNA expression in pulmonary microvascular endothelial ceils (PMVECs) in rats. Methods Pulmonary microvascular endothelial ceils obtained from 24 h old neonatal SD rats were cultured in DMEM liquid culture medium. The 2nd-4th generation PMVECs were inoculated on 6-well plates (5×105). The experiment was performed in two parts. In part Ⅰ different concentration of AngⅡ 0, 10-9, 10-8, 10-7, 10-6mol/L (group Ⅰ- Ⅴ) were added into the PMVECs. The expression of Apelin mRNA and APJ mRNA was determined at 24 h after addition of Ang Ⅱ by RT-PCR. In part Ⅱ the cells were exposed to 10-7 mol/L Ang Ⅱ. The expression of Apelin mRNA and APJ mRNA was determined immediately and at 1, 6, 12, 24, 48 h(group Ⅰ-Ⅵ) after addition of Ang Ⅱ by RT-PCR. Results In part Ⅰ Apelin mRNA expression was significantly higher in group Ⅱ (Ang Ⅱ 10-9 mol/L) but lower in group Ⅲ-Ⅴ (AngⅡ 10-8, 10-7, 10-6 mol/L) than in group Ⅰ (control, Ang Ⅱ 0 mol/L). The APJ mRNA expression was significantly lowered in group Ⅱ-Ⅴ in a dose-dependent manner as compared with control group (group Ⅰ). In partⅡ beth Apelin mRNA and APJ mRNA expression exhibited a bi-phasic response to AngⅡ 10-7 mol/L, increased at first and was then decreasing with time. The Apelin mRNA and APJ mRNA expression reached the peak at 1 h of incubation with Ang Ⅱ respectively. Conclusion Ang Ⅱ decreases both Apelin mRNA and APJ mRNA expression in PMVECs in a dose and time dependent manner. The down-regulation of Apelin mRNA and APJ mRNA expression may be involved in the mechanism of injury to PMVECs.

Objective To evaluate the statues of P-selectin and chang of D-dimer in vivo in patients with deep venous thrombosis(DVT)and to observe how to vary under interneving of medicines.Methods P-selectin and D-dimer of fourty patients and twenty normal subjects were fluo-rescencelabled with its corresponding monoclonal antibodies by flow cytometry(FCM)and immune method respectively.Results In the early stage,P-selectin and D-dimer of patients with DVT is higher than that in normals,and they significantly decreased in different time after patients were treated.Compared with patients who were used on-sodium ozagrel,patients used sodium ozagrel have different P-selectin(P＜0.05),but D-dimer was similar(P＞0.05)after fourteen days.One month later,P-selectin and D-dimer of DVT patients were lower.However,the positive rate of P-selectin of DVT was still higher than normal subjects.Conclusions The platelet has been actived in vivo in patients with DVT,so do fibrinolysis.Sodium ozagrel can decrease the action of platelet.P-selectin and D-dimmer may be used in diagnose.Post-discharge patients are still high-risk group and must be followed-up regularly.
