Objective: To construct an angiopoietin-like protein 2(ANGPTL2) expression vector and obtain ANGPTL2 over-expression endothelial cell strains.Methods: Plasmid phrGFP-C was used to amplify hrGFP protein coding sequence by polymerase chain reaction.The amplified sequence was cloned into the A multiple cloning sites of pIRES to construct plasmid pIRES-hrGFP.Complementary oligonucleotides containing the recognition sequence of BamH I,Sal I,Xba I and SSe8387 I were synthesized,annealed and cloned into a BamH I site on the backbone of plasmid pIRES-hrGFP to obtain vector pIRES-hrGFP-MS.ANGPTL2 cDNA was cloned by RT-PCR while human renal RNA was used as the templet and then inserted into the B multiple cloning sites of the vector pIRES-hrGFP-MS.The newly constructed ANGPTL2 expression vector pIRES-hrGFP-MS-ANGPTL2 was linearized by Xba I and introduced into human umbilical vein endothelial cells.ANGPTL2 over-expressed endothelial clones were screened out by G418 selection and identified by the expression levels of both hrGFP and ANGPTL2 genes in these cell clones.Results: The ANGPTL2 expression vector pIRES-hrGFP-MS-ANGPTL2 was constructed successfully and two ANGPTL2 over-expression endothelial strains were obtained.The cells displayed a significantly extended appearance quite different from that of the control cells.Conclusion: The successful construction of the ANGPTL2 expression vector pIRES-hrGFP-MS-ANGPTL2 and the obtainment of two ANGPTL2 over-expression HUVEC strains have paved the way for further investigation into the function of ANGPTL2 and its possible role in diabetic nephropathy.

The calibration curve of hesperidin was linear in the range 0.506 -2.53 ?g,with the correlation coefficient of 1.000 0(n=5).The average recovery hesperidin was 100.43%(RSD=1.39%,n=6). The average recovery of cinnabaris was 98.30%(RSD=1.06%,n=6). CONCLUSION :The methods are simple,accurate and reproducible. They are suitable for the quality control of Anshen Wendan Pill.

Objective To study the method, advantage and shortcoming of mini-laparoscopic treatment for indirect inguinal hemia in children. Methods 136 cases with indirect inguinal hernia(right:75cases,left:44 cases,bilateral:17 cases) had been treated by high ligation with mini-laparoscopy. Results The mean operation time was 10 mmin for unilateral hernia and 23 mmin for bilateral hernia. Among 119 cases with unilateral hernia,38 cases had been found with contralateral latent hernia. The mean of postoperative inhospital stay were about 1 ～ 2 day(s). All patients had been followed-up for 3 ～ 12 months,there were only 2 cases recurrence found but no complications was detected.Conclusion Mini-laparoscopic high ligation for indirect inguinal hernia in children is a single, safe, satisfactory, effective,and minimally invasive surgical method.

Objective:To study the effect of recombined TNF ? combined with induction of apoptosis and its relation with expression of bcl 2 in SW480 human colon cancer cells.Methods:The inhibitive effect of 5 Fu and TNF ? was measured by MTT.Apoptosis of colon cancer cells was studied by TUNEL.The expression of bcl 2 gene was determined by immunohistochemical analysis.Results:After SW480 colon cancer cells were treated with combination in various concentration of 5 Fu and 3 000 U/mL of TNF ? for 48 h,MTT assay revealed a significant decrease of relative viability in compasrison to the control.When SW480 colon cancer cells were treated with 3 000 U/mL of TNF ? and 125 ug/mL of 5 Fu in combination for 48 h,TUNEL method showed the number of nick end positive cells was significantly increased in comparison to the control.The expression level of bcl 2 gene lowered significantly than that of the control group.Conclusion:These results confirmed that combined TNF ? and 5 Fu could synergistically induce apoptosis in SW480 cells and decrease the expression level of bcl 2 gene.

Objective To explore the application of mini-laparoscopy in the diagnosis and management of nonpalpable undescended testis in children.Methods 38 cases of impalpabal testes(46 testicular) had been operated by mini-laparoscopy in children with cryptorchidism.Results 38 children with nonpalpable undescended testis (46 testicular) had been operated by mini-laparoscope.Results After laparoscopic exploration,inguinal probe and postoperative pathology,it had been confirmed that 2 testicular were absent,34 testicular were found in high inguinal location,10 testicular were located in intraperitoneal cavity.In addition to the absent testicular,the rest had been performed with mini-laparoscope:one period descent fixation 41 testes,Fowler-Stephens (F-S) installment orchiopexy three testes.Follow-up with side testicular atrophy 2,including one period orchiopexy a testis,F-S installment fixation a testicular; Testicular rebound 1,who had been operated with one phase of testicular descent fixtion.Conclusion For inguinal failed to find the testicular,children with cryptorchidism should be done by laparoscopy because of its positioning accuracy,and most children can do a period drop fixed,but for those really intraperitoneal more exalted person,stage surgery should be needed.Its overall treatment effect is satisfactory and is worth popularizing.

Objective To observe the influence of the theory of planned behavior (TPB) in teaching patients with cervical spondylosis about their disease.Methods A hundred cervical spondylosis patients were assigned according to their admission order into an experimental or a control group.The control group received conventional health education and health education materials, including oral health education.With the intervention group,the TPB was used to design their nursing, and they received behavioral intervention addressing attitude, subjective norms and behavior control.Both groups were assessed for the degree of pain using a six-point pain score, health behavior, and recurrence, before the experiment and after 6 months.Results After six months both groups had significantly improved pain scores, but the average improvement in the intervention group was significantly greater.Their health behavior was also significantly better except for the prevention of pharyngeal infection and keeping warm.Conclusions The TPB can significantly relieve the pain and improve the health behavior of spondylosis patients, and reduce the recurrence rate.

Objective To evaluate the relationship between serum magnesium and coronary artery calcification (CAC) and their associated factors.Methods 131 patients with chronic kidney disease on regular hemodialysis (HD) were recruited into this study from December 2014 to December 2015 in our center.Demographic and clinical data of selected patients were collected.Serum fibroblast growth factor 23 (FGF-23) level was quantified by enzyme linked immunosorbent assay(ELISA).Quantification of coronary artery calcification score (CACs) was determined by multi-slice spiral computed tomography (MSCT).The relationships between serum magnesium and FGF-23 level,CACs,demographic and clinical data were investigated.Results Patients were divided into low serum magnesium group,normal serum magnesium group and high serum magnesium group according to their serum magnesium levels.There were significant differences in the distribution of diabetes history,serum phosphorus,serum albumin,serum pre albumin,serum uric acid among these three groups(P ＜ 0.05).A significant positive correlation was confirmed between serum magnesium level and serum albumin,serum pre albumin,serun phosphorus and serum uric acid by Pearson correlation analysis and Spearman correlation analysis (r=0.389,0.234,0.200,0.234,P=0.000,0.007,0.022,0.007,respectively).According to the degree of CAC,all maintenance hemodialysis (MHD) patients were divided into non-calcification group,low calcification group,moderate calcification group and high calcification group,and there were significant differences in the distribution of the age,serum phosphorus,serum magnesium,FGF-23 levels among these groups (P ＜ 0.05).Spearman correlation analysis showed that CACs was positively correlated with age,FGF-23,serum phosphorus (r=0.309,0.277,0.180,P=0.000,0.001,0.040,respectively),while negatively correlated with serum magnesium level (r=-0.238,P=0.006) in patients with MHD.The independent risk factors of CACs were aging,high level of FGF-23 in MHD patients by using ordinal logistic regression.However,Hypermagnesemia was a protective factor.Conclusions The history of diabetes,low serum albumin,phosphorus metabolism disorder and CAC are associated with hypomagnesemia in MHD patients.In MHD patients,aging as well as high level of FGF-23 are the risk factors of CAC,and hypermagnesemia is a protective factor of CAC.
