[Objective]To prove the feasibility of using the distance between sagittal plane of the spinal process and the enter point to individualize the placing of pedicle screw.[Method]Thirty spine specimen were collected and divided into two groups,data were measured,such as the width of the pedicle,distance between the enter point and anterior border of the vertebra,distance between sagittal plane of the spinal process and the enter point,angle from the longitudinal axis of the pedicle to sagittal axis of the vertebra,angle from the longitudinal axis of the pedicle to vertical line of the operating table.In group one the pedicle screws were placed with the help of the distance between sagittal plane of the spinal process and the enter point,the other by the method advised by Ebraheim.CT scan was applied to evaluate the place of the screws,according to the perforation extent,they were classified into 4 grades:A=totally in the pedicle;B=perforation extent4mm.[Result]The individualized group showed much lower perforation rate than the traditional method group in T3~10,and similar in T1,T2,T11,12.[Conclusion]It can obviously improve the accuracy of the pedicle screw placement to use the distance between sagittal plane of the spinal process and the enter point to localize the enter point,especially when anatomic landmark such as articulationes zygapophysiales and transverse process change.

Objective To observe the therapeutic effects of treating shingles with venesection and cuppingplus Yunnan White Powder external application and to observe the effect of mental intervention and nursing on clinical healing time.Methods 100 cases with shingles were randomly recruited into two treatment groups(Group A and Group B)and a control group.Both treatment groups were treated with venesection and cupping plus yunnan white powder external application,in addition,group B was treated with mental intervention and nursing care.The control group was treated with Aciclovir ointment.Results As compared with the control group,both treatment groups showed significant difierences in the time of relieving pain,removing swell,forming a scab,and healing(P＜0.01);Compared with group A,group B showed a shortened healing time with P＜0.05.Conclusion It is effective to treat shingles with venesection and cupping plus yunnan white powder.Mental Intervention and nursing can promote the healing time and improve the degree of satisfaction.

Objective Signal transducers and activators of transcription 3 (STAT3) silenced by RNA interference (RNAi) technique were used to induce the apoptosis and growth inhibition in T24 and 5637 bladder cancer cells. Methods Three recombinant plasmids pGenesil-1-shRNA-STAT3 was constructed and transfected into T24 and 5637 cells. The expression of STAT3 gene was detected by RT-PCR and Western blotting. FCM was used to observe the apoptosis in T24 and 5637 cells. Results pGenesil-1-shRNA-STAT3 was successfully constructed, and transfected into T24 and 5637 cells. RT-PCR and Western blot analysis demonstrated that pGenesil-1-shRNA-STAT3 could significantly inhibit the expression of STAT3 in T24 and 5637 cells; FCM results show that it could suppress the growth of 1'24 and 5637 cells. Conclusion pGeneSiI-1-shRNA-STAT3 could significantly inhibit STAT3 expression, suppress the growth of T24 and 5637 cells.

Background and purpose:Colorectal cancer is one of the most common cancers worldwide as well as a prevalent cause of morbidity and mortality in China.Mustard seed and its components have been reported to possess anticancer properties.The purpose of this study was to investigate the effect of a diet mixed with mustard seeds (MS)on the prevention of colorectal tumorigenesis in Kunming mice induced with azoxymethane.Methods:Sixweek-old female Kunming species mice of were randomly divided into 4 different groups:AOM alone,AOM+5%MS,AOM+10%MS,and the untreated control group.Colorectal tumorigenesis was subcutaneously induced by injecting 10 mg/kg of AOM once a week,for 3 weeks.Different doses of MS were administered in the diet during this study.Thirtytwo weeks after initiation,the mice were put down through cervical dislocation.The colon and recta of the mice were isolated and flushed with nonnal but ice-cold saline.The site,size,and number of colorectal tumors were recorded.The incidence of colorectal tumor in each group was determined.Results:No tumors were found in the control group.Compared to AOM-treated control group(86.7%),the occurrence of colorectal tumors was reduced to 60.0%when administered with a 5%diet of mustard seeds and to 41.7%(P＜0.05)with a diet of 10%mustard seeds.Tumor burden (tumors/mouse)was 2.2±1.2 in the AOM-treated control group whereas it was reduced to 1.1±1.1(P＜0.05)in the 5%diet of mustard seeds and 0.7±0.9(P＜0.05)in the 10%diet of mustard seeds.Conelusion:The results indicate that a diet of mustard seeds is able to inhibit the development of colorectal cancer in mice induced by AOM,suggesting possible future application of MS as a chemopreventive agent for colorectal cancer.

Objective To discuss the effects of bone marrow-derived mesenchymal stem cells (MSCs) on vascular endothelial growth factor (VEGF) in lung tissue and in plasma, and extra-vascular lung water at the early stage of smog inhalation injury. Method The rabbit model of smog inhalation injury was established by using home-made smog generator, and the rabbit models were randomly(random number) divided into control group (group S, n = 32) and MSCs treatment group (group M, n = 32). Ten mL phosphate-buffered saline (PBS) was injected into ear marginal vein immediately after injury in rabbits of group S. The third generation of MSCs 1/10/10 mL PBS was injected into ear marginal vein immediately after injury in rabbits of group M. The levels of VEGF in peripheral blood and lung tissue were neasured 0 h,2 h,4 h and 6 hours after injection respectively, and analyzed. The right lung of rabbits was taken out to measure and calculate lung water mass fraction after experiment.Results In lung tissue, the levels of VEGF decreased gradually in group S (P ＜ 0.05), and though the levels of VEGF in lung tissue appeared with significant decreasing trend in group M (P ＜ 0.05), they were still higher than those of group S at corresponding intervals ( P ＜ 0.05). In peripheral blood, the levels of VEGF increased gradually in group S ( P ＜ 0. 05), and the levels of VEGF in group M appeared with markedly increasing trend ( P ＜ 0.05),but they were lower significantly than those in group S at corresponding intervals ( P ＜ 0.05). Conclusions MSCs engraftment to the rabbits with smog inhalation injury could increase VEGF in lung tissue, decrease VEGF in plasma and reduce extra-vascular lung water, showing protective effect on smog inhalation injury to a certain extent.

Objective To investigate the association of single nucleotide polymorphism (SNP) rs13333226 in uromodulin (UMOD) gene with diabetic kidney diseases (DKD) in Han population in Tianjin,China.Methods A total of 210 type 2 diabetes (T2DM),90 normal controls (NC) and 280 DKD patients were recruited.According to the level of estimated glomerular filtration rate (eGFR),the DKD subjects were further subdivided into three groups:GFR≥90 ml/min group (n=105),60 ml/mim≤GFR ＜ 90 ml/min group (n=84) and GFR ＜ 60 ml/min group (n=91).Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for UMOD rs13333226C genotyping.Results The frequencies of AA,GA,GG genotype were 27.8％,58.9％,13.3％ in NC group and 41.0％,48.6％,10.5％ in T2DM group and 54.3％,36.1％,9.6％ in DKD group.The frequency of G allele was 42.8％ in NC group,34.8％ in T2DM group and 27.7％ in DKD group.The genotype distribution of UMOD was statistically significant between NC group and DKD group,and between T2DM group and DKD group (P ＜ 0.05).G allele of UMOD was an independent protective gene polymorphism of DKD in Logistic regression (B=-0.248,Wald=8.012,P=0.021,OR=0.780,95％ CI 0.612-0.968).Conclusion The G allele of UMOD gene may be an independent protective factor of DKD in Han population in Tianjin,China.
