ObjectiveTo investigate the effect of artesunate on the expression of vascular endothlial growth factors(VEGF)and VEGFR in SHI-1 cell line.MethodsEnzyme-linked immunosorbent assay analysis was performed to detect the amount of VEGF in culture supernatants of SHI-1 cell in the condition of artesunate or not. The expression of VEGFR1 and VEGFR2 in SHI-1 cell in the condition of artesunate or not were detected by flow cytometry.ResultsWithout artesunate,the concentration of VEGF in the culture supernatant of SHI-1 cell were (980.3±2.2) pg/ml in 24 h and (982.4±2.3) pg/ml in 48 h. The expression of VEGFRI in SHI-1 cell were (6.40±3.11) ％ in 24 h and (6.45±2.85) ％ in 48 h. The expression of VEGFR2 in SHI-1 cell were (13.90±2.26) ％ in 24 h and (13.95±1.96) ％ in 48 h. With artesunate at 5, 10, 20 ng/ml, the concentration of VEGF in culture supematant of SHI-1 cell were (234.6±1.8)pg/ml, (114.9±1.6)pg/ml, (108.8±1.5) pg/ml in 24 h and (62.3±1.7) pg/ml, (60.9±1.6) pg/ml, (32.7±1.7) pg/ml in 48 h, respectively. The levels of VEGF in SHI-1 cells treated with artesunate at different concentrations decreased significantly (P ＜0.05).There was significant difference between 24 hours group and 48 hours group(P ＜0.05).The expression of VEGFR1 in SHI-1 cell were (4.30±2.21) ％, (4.20±1.37) ％, (3.90±1.86) ％ in 24 h and (3.80±2.87) ％, (3.60±1.73) ％, (3.00±1.82) ％ in 48 h, respectively. The expression of VEGFR1 in SHI-1 cell treated with artesunate at different concentrations were not significantly different (P ＞0.05). No significant difference between 24 hours group and 48 hours group was observed (P ＞0.05). VEGFR2 expression of SHI-1 cell were(4.40±1.15) ％, (3.10±0.68) ％, (1.10±0.72) ％ in 24 h and (3.00±1.68) ％, (2.20±0.93) ％, (0.60±0.92) ％ in 48 h, respectively. The results indicated that the expression of VEGFR2 in SHI-1 cells treated with artesunate at different concentrations reduced significantly (P ＜0.05),but there was no significant difference between 24 h group and 48 h group (P ＞0.05). ConclusionThe concentration of VEGF in SHI-1 cell was high, and artesunate can down-regulate the expression of VEGF and VEGFR2,but the effect of artesunate on the VEGFR1 was not significant.

AIM: To investigate the effect of VEGF gene transfer on matrix metalloproteinases(MMPs) and tissue inhibitor of metalloproteinases(TIMPs) expression after vascular balloon injury. METHODS: 90 New Zealand white rabbits were divided into 3 groups randomly: group Ⅰ(balloon injury group), groupⅡ (pAdtrackCMV group) and group Ⅲ(pAdtrackCMV-VEGF165 group). Hypercholesterol diet was given for 7 days before experiment and continued to receive until the animals were killed. Each group were divided into five subgroups according to the sacrifice time. Blood samples and iliac arteries were harvested for further analysis. RESULTS: In group Ⅰ and Ⅱ, MMP2 and TIMP1,2 expressions were detected during the whole process ,while in group III ,MMP1,2,9 and TIMP1,2 could be detected from 3 days after gene transfer and reached the highest level at 1 week and could not be detected at 8 week. CONCLUSIONS: Imbalance expression of MMPs and TIMPs occurred after vascular injury and this may be the reason of pathological remodeling. Local phAdtrackCMV-VEGF165 transfer could specifically change the expression of MMPs and facilitate the positive remodeling process after vascular injury.

OBJECTIVE:To compare the efficacy and safety of low molecular weight heparin and rivaroxaban in the preven-tion of deep venous thrombosis after spinal surgery. METHODS:Totally 276 patients with high risk factors after spinal surgery were randomly divided into control group and observation group. The patients in the two groups were used elastic stockings to physi-cally prevent deep venous thrombosis from the postoperative first day to continue 3 months;based on it,control group was subcuta-neously injected with 1 low molecular weight heparin from the postoperative first day,once a day. Observation group was orally treated with 1 Rivaroxaban tablet,once every night. The treatment course for 2 groups was 2 weeks. The clinic data was observed, including clinical efficacy,superficial femoral vein diameter(FSV),popliteal vein diameter(POPV),prothrombin time(PT),fi-brinogen degradation products(FIB)and D- dimer(DD)before and after treatment,incidence of deep venous thrombosis and ad-verse reactions. RESULTS:There were no significant differences in the total effective rate and deep venous thrombosis and inci-dence of ADR between 2 groups(P>0.05). After 3 months,compared with before,there were no significant differences in the FSV and POPV between 2 groups (P>0.05);POPV in control group was significantly lower than before and observation group, there was statistical significance(P<0.05). After 1 week,compared with before,there was no significant difference in the PT be-tween 2 groups(P>0.05);the FIB and D-D were significantly higher than before,there was statistical significance(P<0.05), however,there were no significant differences between 2 groups(P>0.05);after 4 weeks,PT in 2 groups was significantly high-er than before,there was statistical significance(P<0.05),however,there were no significant differences between 2 groups(P>0.05);FIB and D-D were significantly higher than before,and observation group was lower than control group,there was statisti-cal significance(P<0.05). CONCLUSIONS:Both efficacy and safety of low molecular weight heparin and rivaroxaban in the pre-vention of deep venous thrombosis after spinal surgery are good. However,rivaroxaban is better than low molecular weight heparin in improving blood coagulation function.

Objective To explore the depression and anxiety status of patients with refractory irritable bowel syndrome (IBS)and its subtypes.Methods In this large sample,multi-center,prospective survey(Registration number in Chinese Clinical Trial Registry:ChiCTR-TRC-12001969),the patients who conformed to the Rome Ⅲ criteria for IBS were recruited from the department of gastroenterology of three hospitals in Guangdong province from June 2012 to September 2012.And 100 healthy subjects from the examination center of hospitals were recruited at the same time.The 17-item Hamilton Depression Rating Scale(HAMD) and the 14-item Hamilton Anxiety Rating Scale(HAMA) were used to analyze the depression and anxiety,respectively.Results 9802 patients were collected from department of gastroenterology,and a total of 1128 (11.5 ％) patients were diagnosed as IBS.601 of questionnaires were collected,including 142 (23.6％) of refractory IBS and 459 (76.4％) of non-refractory IBS.The incidences of depression,anxiety,depression and anxiety and the HAMD,HAMA scores were higher in refractory IBS group than those in the non-refractory IBS and control group,((66.2％ vs 23.3％ vs 9.0％),P＜0.05 ;(65.5％ vs 28.5％ vs 10.0％),P＜0.05;(58.5％ vs 17.9％ vs 5.0％),P＜0.05;(9.77 ±5.16)vs(5.48 ±4.03)vs(1.66±2.50),P＜0.05;(9.75 ±5.08)vs(5.91 ±3.80)vs(2.26 ±2.68),P＜0.05).And the incidences of moderate-severe depression and moderate-severe anxiety were higher in refractory IBS group than those in the non-refractory IBS and control group ((8.5％ vs 1.3％ vs 0),P＜0.05; (15.5％ vs 3.7％ vs 0),P＜0.05).The incidences of depression,anxiety,depression and anxiety and the HAMD scores were not obviously different among IBS-D,IBS-C,IBS-M and IBS-U subtypes of refractory IBS (P ＞ 0.05).However,the HAMA scores of IBS-D and IBS-M were higher than that of IBS-U((10.10 ± 5.03) vs(7.55 ± 3.22),P ＜ 0.05 ; (12.08 ±6.89) vs (7.55 ± 3.22),P ＜ 0.05).Conclusion The high incidences of depression,anxiety and depression and anxiety,and the serious degrees of depression and anxiety existed in the patients with refractory IBS.And these are the important causes for refractoriness in these patients.

Objective To explore the eating behaviors associated with refractory functional dyspepsia (RFD).Methods In this multicenter,prospective trial,1341 new outpatients with functional dyspepsia (FD) from three Guangdong hospitals who had been diagnosed according to the Rome Ⅲ criteria were enrolled from May to September in 2012.One hundred healthy volunteers were also enrolled as controls.A questionnaire was used to obtain data,and logistic regression analysis was used for analysis.Results ①RFD was diagnosed in 24.4％ of the FD patients.②Unhealthy eating behaviors were significantly greater in patients with RFD and non-RFD than in the normal controls.Patients with RFD skipped meals more often,ate extra meals,and preferred sweets and gasproducing foods (P ＜ 0.05).③A comparison among the non-RFD subtypes,showed that those with epigastric pain syndrome had a greater preference for spicy foods (47.5 ％ vs 35.7 ％,P ＜ 0.05),and those with postprandial distress syndrome had a greater preference for sweets(50.0％ vs 36.4％,P ＜ 0.05) and gas-producing foods (14.9％ vs 7.1％,P＜0.05).Those with both subtypes skipped more meals (30.1％ vs 17.0％,P ＜ 0.05),and ate extra meals (15.0％ vs 6.5％,P＜0.05).④Logistic regression analysis showed that meal skipping(95％ CI,1.177 ～2.272; P=0.003),eating extra meals (95％ CI,1.015 ～2.604; P =0.043),and a preference for sweets (95 ％ CI,1.040 ～ 1.757 ; P =0.024) and gas-producing foods (95 ％ CI,1.022 ～ 2.306 ; P =0.039) were risk factors for RFD.Conclusion Unhealthy eating behaviors,especially,meal skipping,eating extra meals,preferring sweets and gas-producing foods correlate with RFD and these behaviors may be the key reasons for the refractory characteristic of RFD.

BACKGROUND:There are many ways for surgical treatment of distal radius fractures. Both volar locking plates and Kirschner wires are common methods. Doctors have considerable flexibility in the choice of the ways of fixation, but both at home and abroad there is no comparison between the effects of the two operations for treating distal radius fractures. OBJECTIVE:To systematicaly review the differences in effectiveness and safety of volar locking plates versusKirschner wires for distal radial fracture. METHODS:Databases such as CBM, CNKI, VIP, PubMed and Cochrane Library were electronicaly searched.Chinese Journal of Orthopaedics,Chinese Journal of Orthopaedic Trauma,Chinese Journal of Trauma andJournal of Practical Orthopaedics were searched by hand. In strict accordance with inclusion and exclusion criteria, articles were screened. Methodological quality of included studies was evaluated according to Cochrane Handbook. Data were extracted, and then analyzed with RevMan 5.2 software. RESULTS AND CONCLUSION:Nine randomized controled trials were included. Meta-analysis results demonstrated that upper limb function scores were better in the volar locking plate group than in the Kirschner wire group [MD=-4.55(-7.89,-1.21),P=0.008] at 3 months of folow-up and [MD=-3.13(-6.08,-0.18),P=0.004] at 12 months. The incidence of infection was lower in the volar locking plate group than in the Kirschner wire group [OR= 0.42(0.23, 0.79),P=0.007]. No significant difference in incidence of complex regional pain syndrome [OR=0.28(0.05, 1.38),P=0.12], incidence of carpal tunnel syndrome [OR=0.75(0.20, 2.76),P=0.66] and tendon injury [OR= 1.66(0.51, 5.41),P=0.64] was detected between the volar locking plate group and Kirschner wire group. These results indicated that compared with the Kirschner wire, volar locking plate fixation for the repair of distal radial fracture is safe and effective. In the permission of economic circumstances, it is suggested that elder osteoporosis patients with distal radial fracture should receive plate fixation.

Objective To investigate the correlation between histone deacetylase 1(HDAC1) and vascular endothelial growth factor(VEGF) in the patients with lung adenocarcinoma.Methods Eighty cases of lung adenocarcinoma in our hospital from August 2014 to April 2016 served as the research subjects,and contemporaneous 80 individuals undergoing healthy physical examination were taken as the control group.The fasting venous blood sample was collected in all subjects.Then serum HDAC1 and VEGF levels were detected by ELISA.The differences of serum HDAC1 and VEGF expression levels were compared between the two groups.The HDAC1 and VEGF expression levels in the patients with different characteristics of lung adenocarcinoma and the relation between serum HDAC1 and VEGF concentrations were analyzed.Furthermore the possible influence factors of HDAC1 protein expression level in the patients with lung adenocarcinoma were analyzed.Results The HDAC1 levels in the control group and observation group were(329.56 ± 23.83) ng/L and(568.20 ± 35.40) ng/L,the difference was statistically significant(t=23.576,P=0.000).The VEGF levels in the control group and observation group were(40.26±9.82)ng/L and(296.56±19.80)ng/L respec tively,the difference was statistically significant(t=31.154,P=0.000).The HDAC1 protein level had statistical difference among different genders,ages,clinical stages and smoking history,the HDAC1 protein level in male,age ＞60 years old,clinical stage Ⅲ,V and patients with smoking history were higher(P＜0.05).The Pearson correlation analysis results showed that serum HDAC1 in the patients with lung adenocarcinoma was positively correlated with VEGF protein concentration(r=0.526,P =0.000).The Logistic regression analysis showed that influence factor of HDAC1 protein expression level in the patients with lung adenocarcinoma was clinical stage.Conclusion The high expression of HDAC1 protein in lung adenocarcinoma patients may also simultaneously regulate the VEGF expression,thus promotes the development of lung adenocarcinoma.
