Objective To construct an efficient SALL4 shRNA vector and transfect it into THP-1 cells for investigating the effect of SALL4 in leukemia. Methods Four SALL4-specific siRNA to aim at different SALL4 mRNA target sites and a negative control siRNA were designed, and pGPU6/GFP/Neo/SALL4 shRNA vectors were constructed. THP-1 cells were transfected and the expression of SALL4 in shRNA detected, and blank control and negative control were also designed. Results The results of real time quantitive PCR and Western blotting both exhibited that the interference effect of pGPU6/GFP/Neo/SALL4 shRNA-B vector was optimal targeting to mRNA-1122 target site and down-regulated the expression of SALL4 more significant(P <0.05). Conclusion Successfully construction of SALL4 siRNA vector by choosing SALL4 shRNA-B would be useful to accomplish study of SALL4.

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 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.

Background:Gastric cancer is the result of comprehensive interactions among Helicobacter pylori(Hp)infection, environmental factors and host genetic factors. It has been demonstrated that rs2294008 polymorphism in prostate stem cell antigen(PSCA)gene is associated with increased risk of non-cardia gastric cancer. Aims:To investigate the relationship between PSCA rs2294008 polymorphism and precursors of gastric cancer. Methods:A total of 398 patients with gastric intestinal metaplasia( n = 328)and intraepithelial neoplasia( n = 70)from Nov. 2009 to Nov. 2015 at the Qingdao Municipal Hospital were enrolled,and 416 healthy subjects were served as controls. Genotype of PSCA rs2294008 was determined by direct DNA sequencing of PCR products,and Hp infection was examined by rapid urease test. Results:Significant difference in frequencies of CC,CT and TT genotypes of PSCA rs2294008 was observed between case and control groups(P = 0. 011);the frequency of TT genotype was significantly higher in case group than in control group (16. 3% vs. 9. 4% ,P = 0. 003). Compared with individuals carrying CC genotype,TT genotype carriers were found to be associated with a higher risk of precursors of gastric cancer(oR = 1. 840,95% CI:1. 174 ~ 2. 886). Taken individuals negative for Hp infection and carrying C allele(CC + CT)as reference,risk of precursors of gastric cancer was significantly increased by Hp infection(oR = 2. 389,95% CI:1. 799 ~ 3. 173)and Hp infection in combination with TT genotype (OR = 3. 335,95% CI:1. 935 ~ 5. 749),whereas TT genotype alone only slightly increased the risk(OR = 1. 783,95%CI:0. 900 ~ 3. 530). Conclusions:PSCA rs2294008 polymorphism is significantly associated with susceptibility to precursors of gastric cancer and Hp infection might further increase the risk in TT carriers.

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 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.

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.
