OBJECTIVETo compare the efficacy between elongated needle therapy and regular needle therapy at Tiantu (CV 22) on the basis of xingnao kaiqiao (activiting brain and regaining consciousness) acupuncture therapy so as to explore the effective therapeutic method in treatment of dysphagia induced by bulbar palsy.

METHODSSeventy one cases of dysphagia induced by bulbar palsy were randomized into two groups. The xingnao kaiqiao acupuncture therapy was applied at Shuigou (GV 26), Neiguan (PC 6), Sanyinjiao (SP 6) and the others in the two groups. In the elongated needle therapy group, on the basis of xingnao kaiqiao acupuncture therapy, the elongated needle was used to puncture Tiantu (CV 22). In the regular needle therapy, the regular acupuncture technique was used at Tiantu (CV 22). In both groups, the treatment was given once a day in a week except Sunday and lasted for 4 weeks totally. Before and after treatment, the swallowing condition and the standardized swallowing assessment (SSA) were observed in the patients and the efficacy was compared between the two groups.

RESULTSThe total effective rate was 97.2% (35/36) in the elongated needle therapy group, which was better than 77.1% (27/35) in the regular needle therapy group (P<0.05). After treatment, SSA score was reduced significantly as compared with that before treatment in the two groups (both P<0.05). SSA score in the elongated needle therapy group was reduced much more apparently as compared with that in the regular needle therapy group after treatment (P<0.05).

CONCLUSIONOn the basis of the xingnao kaiqiao acupuncture therapy, the elongated needle therapy at Tiantu (CV 22) achieves the superior effect on bulbar palsy-induced dysphagia as compared with the regular acu- puncture at Tiantu (CV 22).

ObjectiveTo investigate the relationship between the oxidative injury induced by low glucose and mitochondrial membrane potential in HUVEC-12 cells. Methods Human umbilicalvein endothelial cells HUVEC-12 were cultured in low concentration glucose for 4 h.Cell viability of HUVEC-12 cell was assessed with MTT assay.Dihydroethidium (DHE) was used as a reactive oxygen species (ROS)capture, which was detected the mean fluorescence intensity of samples and Rhodamine 123 as a fluorescence detector was to measure the level of mitochondrial membrane potential (MMP) in cells.Results Comparing to HUVEC-12 cells viability in 5.5 mmol/L glucose group (96.80 ±3.20)％, cells exposed to 2.8 mmol/L glucose group (66.40 ± 1.60) ％ and 0 mmol/L glucose group (58.93 ± 1.67) ％ were decreased by 32％ and 40％ respectively (P ＜ 0.01).ROS level of 5.5 mmoL/L glucose group, 2.8 mmol/L glucose group and 0 mmol/L glucose group were 0.59 ± 0.02, 0.74 ± 0.04 and 0.88 ± 0.05,respectivdy, increased by 25％ in cells exposed to 2.8 mmol/L glucose and by 48％ in cells without glucose exposure comparing to 5.5 mmol/L glucose group (P ＜0.01) ; MMP levels of 5.5 mmol/L glucose group,2.8 mmoL/L glucose group and 0 mmoL/L glucose group were 148.83 ± 3.51, 271.07 ± 19.54 and357.74 ±51.32 respectively, increased to 1.8 times in cells exposed to 2.8 mmol/L glucose and to 2.4times in cells without glucose exposure comparing to 5.5 mmoL/L glucose group (P ＜ 0.01).Conclusion Low glucose leads to injury in HUVEC-12 cells, which is probably induced by the oxidative stress via the increasing MMP.

Objective To study the relationship between the positive expression of human leukocyte antigen B27 (HLA-B27) in different age groups and genders in Uygur and Han nationality in Xinjiang,and explore the clinical value of HLA-B27 in different ethnic groups.Methods From January 2013 to November 2016,1 416 cases of Uygur and Han patients with positive expression of HLA-B27 were detected by flow cytometry.There were 369 cases of Uygur and 1 047 cases of Han.Results Independent samples t-test showed that the positive expression of HLA-B27 in Uygur and Han population was statistically significant (165.22±8.262 vs 163.99±8.113,t=2.479,P=0.013).In male,there was a significant difference in the positive expression of HLA-B27 between Uygur and Han population (165.40 ± 8.237 vs 163.99 ± 8.164,t =2.187,P =0.029).In the age of 41～60 years old and ＞60 years old,the positive expression of HLA-B27 in Uygur was higher than that in Han nationality (166.18 ± 7.650 vs 164.53 ± 8.018,t =2.215,P =0.027;171.63 ± 8.134 vs 167.40 ± 9.469,t =2.126,P=0.035).There was no significant difference in the positive expression of HLA-B27 between Uygur and Han nationality in women,as well as in the age of 20 years and 21～40 years (t=-0.029～1.257,all P＞0.05).Conclusion The investigation showed that the positive expression of HLA-B27 in Uygur was higher than that in Han nationality.The content of HLA-B27 positive expression has racial difference.

Background Serum cystatin C levels can be used to predict morbidity and mortality in patients with cardiovascular disease. However, the clinical relevance of serum cystatin C levels in patients with hypertensive left ventricular hypertrophy (LVH) has rarely been investigated. We designed the present study to investigate whether serum cystatin C levels are associated with cardiac structural and functional alterations in hypertensive patients. Methods We enrolled 823 hypertensive patients and classified them into two groups:those with LVH (n=287) and those without LVH (n=536). All patients underwent echocardiography and serum cystatin C testing. We analyzed the relationship be-tween serum cystatin C levels and LVH. Results Serum cystatin C levels were higher in hypertensive patients with LVH than in those without LVH (P＜0.05). Using linear correlation analysis, we found a positive correlation between serum cystatin C levels and interven-tricular septal thickness (r=0.247, P＜0.01), posterior wall thickness (r=0.216, P＜0.01), and left ventricular weight index (r=0.347, P＜0.01). When analyzed by multiple linear regression, the positive correlations remained between serum cystatin C and interventricular septal thickness (β=0.167, P＜0.05), posterior wall thickness (β=0.187, P＜0.05), and left ventricular weight index (β=0.245, P＜0.01). Con-clusion Serum cystatin C concentration is an independent marker for hypertensive LVH.

Objectives To investigate the relationship of methylenetetrahydrofolate reductase (MTHFR) and methioninesynthase reductase (MTRR) with unexplained recurrent spontaneous abortion (URSA). Methods Case control study was used to select 244 patients with URSA (miscarriage group) and 116 normal women (control group) who were admitted to Tianjin Medical University General Hospital and Tianjin Women’s and Children’s Health Center from January 2013 to March 2015. The oral mucosal epithelial cells were extracted using fluorescence quantitative PCR to detect MTHFR gene C677T, A1298C and MTRR gene loci of A66G single nucleotide polymorphisms (SNP). The relationship between folate metabolism related gene polymorphisms of MTHFR and MTRR and URSA was analysed. Results The frequency of C677T genotype MTHFR was significantly higher in URSA group than that in the control group, and the frequency of CT genotype was significantly lower than that of the control group (P<0.05). There was no significant difference in the frequencies of A1298C MTRR and A66G MTHFR between the two groups. The activity of MTHFR, red cell folate and plasma folate levels were significantly lower in URSA group than those of control group. Homocysteine levels were significantly higher in URSA group than those of control group (P<0.05). There were no significant differences in serum folic acid, red cell folate, homocysteine cysteine levels between patients <35 years old and ≥ 35 years old in URSA group. Conclusion C677TMTHFR gene polymorphism is associated with unexplained recurrent spontaneous abortion.

To study the in vitro anti-angiogenesis effect of three curcumin pigments (curcumin, demethoxycurcumin, bisdemethoxycurcumin). In the study, the inhibitory effect of the three curcumin pigments on proliferation of HUVEC cells induced by OX-LDL and the effect on migration of HUVEC cells were detected. The effect on neovascularization was observed by chorioallantoic membrane (CAM) test. The effect on cell adhesion factors ICAM-1 and VCAM-1 of HUVECs were tested by Real-time RT-PCR. It was found that the three curcumins could inhibit the proliferation of HUVEC cells induced by OX-LDL within the dosage range 4, 8, 16 mg x L(-1), with a dose-dependence. The proliferative effect of curcumins on HUVECs was greater than the other two derivatives (P < 0.01). All of the three curcumin pigments inhibited the migration of HUVEC cells and the angiogenesis of chick chorioallantoic membrane (CAM). The migration inhibition rate of curcumins at middle and high concentrations was greater than the other two (P < 0.01). All of the three curcumin could down-regulate the expression of VEGF and ICAM-1, and curcumins showed more obvious effect in down-regulating VEGF than demethoxycurcumin and bisdemethoxycurcumin(P < 0.01); Bisdemethoxycurcumin showed the most significant effect in down-regulating ICAM-1 (P < 0.01). All of the three showed no remarkable effect on expression of VCAM-1, and only bisdemethoxycurcumin showed the down-regulating effect (P < 0.05). According to the findings, all of the three curcumin pigments could resist angiogenesis by inhibiting proliferation and migration of endothelial cells and down-regulating the expression of VEGF and adhesion molecules ICAM-1.
