The article discusses whether the "Law for Protection of Rights and Interests of Consumers" is applicable to the disposal of medical disputes between doctors and Patienes. From the point of the Principle of exchang of commodities, the relation between doctors and patients is not one of commodity consumption on the basis of exchange at equal value. In terms of the nature of the medical and health cause, hospitals are not operators managing goods. In light of the inherent characteristics of medical service, medical and health work is a special trade of services. In the perspective of law, medical services are no ordinary acts of economically legal relation between doctors and patients,they are rather a special consuming act on the side of consumers and there is a special economically legal relation between doctors and patients. Accordingly, the "Law for Protection of Rights and Interests of Consumers" is not applicable to the diposal of disputes between doctors and patients.

Objective:To explore the subjective quality of life of pediatric patients.Methods:42 children with acute diseases, 38 with chronic diseases and 57 normal children were investigated with Children's Subjective Quality of Life Questionnaire. Results: The subjective life satisfaction were similar in acute disease group (159.9?13.9) and in chronic group (160.0?16.9), which were lower than normal control (165.8?17.6). Multiple regression showed that girls, from urban area, late onset, longer duration, less activities out of class, lack of support from relatives, poor mental health of parents were risk factors. Conclusion: Children with acute or chronic diseases have poorer life quality than normal control.

Objective To investigate the clinical effect and survival quality of raltitrexed and radiotherapy in treatment of esophagus cancer. Methods 100 cases with esophagus cancer were selected. There were 50 cases using raltitrexed combined with concurrent radiotherapy as observation group. Others were treated with 5-Fu combined with concurrent radiotherapy as control group. The clinical therapeutic effect and survival situation of two groups were evaluated. Results After treatment, the total response rate of observation group (86.0%) was higher than control group (58.0%), the differences between the two groups was statistical difference(P<0.05).The one- and two-year survival rates in observation group were higher than control group (χ2 = 4.32, 7.954, P=0.038, 0.005<0.05).There was no significant difference between the two groups in incidence rate of acute esophagitis, acute bone marrow suppression and acute skin reaction. Conclusion The clinical therapy of raltitrexed plus radiotherapy in treatment of esophagus cancer is distinct, and improve the survival time and the quality of life of patients.

AIM: To investigate the possible effect of different Latent membrane protein 1 (LMP1) variants on proliferation characteristics of a human well-differentiated nasopharyngeal carcinoma (NPC) cell line CNE1. METHODS: The plasmids which carried EBV-LMP1 gene cloned from B95-8 lymphocyte (B95-8-LMP1) and NPC tissues (CAO-LMP1) were introduced into CNE1 by liposomal transfection. Expression of LMP1 in CNE1 was identified by RT-PCR and Western blot, respectively. Different Effects of the two EBV-LMP1 variants on proliferation characteristics of CNE1 including growth curve, cell cycle distribution and clony-forming efficiency were investigated by means of crystal violet staining proliferation assay, flow cytometry and plastic plate clony-forming assay, respectively. RESULTS: Two transfected cell lines stably expressing different LMP1 variants were established successfully. Either of the two LMP1 variants increased CNE1 growth rate, proliferation index (PI) and clony-forming rate significantly and CAO-LMP1 had more significant growth-promoting effect on CNE1 than B95-8-LMP1. CONCLUSION: It can be concluded from the study that CAO-LMP1 promotes CNE1 proliferation more effectively than B95-8-LMP1. [

Objective To investigate the correlation between Toll-like receptor2 (TLR2) gene promoter region -597T/C polymorphism and primary ANCA associated small vasculitis (AAV) in Guangxi Han people. Methods A case contrastive control study was adopted in the study. Patients with AAV (patients group, n=110) and healthy people (control group, n = 200) were recruited. Associated serum indexes were detected and polymorphisms of TLR2 gene promoter 597T/C were analyzed by polymerase chain restricted fragment length polymorphisms (PCR-RFLP). Results (1)Three TLR2-597T/C genotypes were discovered in 110 AAV patients, namely, TT, TC and CC, with the frequency of 54.55%,40.00% and 5.45% respectively. And the frequencies of allele T and C were 74.55% and 25.45%. In control group, the genotype frequencies of TT, TC and CC were 56.00%,40.50% and 3.50%, with 76.25% of allele T and 23.75% of allele C. No significant differences were found in neither genotype distribution nor allele frequencies between the patients group and control group ( P > 0 . 05 ) . ( 2 ) Significant differences were found in the incidence of proteinuria rate and the hemoglobin (P< 0.05)in AAV patients. (3)There was no significant difference between AI and CI in TT, TC and CC genotype in AAV patients. Conclusions Polymorphism of TLR2-597T/C may be correlated with the incidence of proteinuria and the level of hemoglobin, while no obvious correlation with the genetic susceptibility of ANCA in vasculitis patients of Guangxi Han people.

In this study, real-time PCR and immunohistochemistry were used to detect coxsakie and adenovirus receptor (CAR) expression. Both localization and quantity were evaluated in the uteri obtained at days post coitus (dpc) 2.5, 4.5, 6.5, 8.5. Outcome of PCR was assessed by 2(-ΔΔCt) method. Image Pro-Plus 6.0 software was used for quantifying mean density of CAR expression in immunohistochemical sections. We found relatively weak CAR expression in the mouse uteri during implantation window. PCR and immunohistochemistry revealed highest CAR expression was detected on dpc 2.5 followed by down-regulation of CAR at dpc 4.5 and 6.5 (with significant difference). At dpc 8.5, CAR expression was increased slightly again. It is concluded that during implantation, the expression of CAR mRNA and protein is declined, resulting in the impairment of tight junction between cavity epithelium cells. After implantation window closure, CAR appears again to maintain epithelium stability. CAR might play an important role during embryo implantation procedure.

Objective To investigate the relationship between putative rs5744168 of Toll-like receptors 5 (TLR5)and ANCA associated small vasculitis (AAV) in Guangxi Han nationality. Methods Polymorphism was analyzed by polymerase chain restricted fragments length polymorphism in 120 cases with AAV and 212 controls. Results (1)There were two genotypes of CC and CT in AAV group and control group. The frequencies distribution of CC and CT in 120 AAV patients were 82.50% and 17.50% respectively and the frequencies of allele C and T 91.25% and 8.75%,respectively. In controls,the genotypefrequencies of CC and CT were 88.68% and 11.3%, and frequencies of allele C and T 94.34% and 5.66%, respectively. No significant difference was found in either genotype distribution or allele frequencies between the patients and the controls ( P > 0 . 05 ) . ( 2 ) Significant reductions in the incidence of BUN, uric acid, quantitative test of 24 h urinary protein and erythrocyte sedimentation rate(ESR) were found in CC genotype (P < 0.05). (3) Binary regression model with a logit link function found total cholesterol was related with AAV. Conclusion The susceptibility of AAV in Guangxi Han population has nothing to do with the polymorphism of rs5744168.In AAV patients, polymorphism of rs5744168 may be associated with ESR, BUN, uric acid and quantitative test of 24 h urinary protein levels.

Objective To detect the clinical effect of posterior reduction combined with H-shaped bone grafting and spinous process replantation for reconstruction of spinal structures in treatment of thoracolumbar fracture.Methods Forty-three patients with thoracolumbar burst fracture treated surgically from February 2008 to June 2012 were reviewed retrospectively.There were 30 male and 13 female patients aged 23 to 55 years (mean,38 years).Fracture resulted from high falls in 21 patients,traffic accidents in 16 patients,and a crush by heavy objects in 6 patients.Denis system was used for classification of fracture and Frankel rating for assessing the degree of nerve damage and recovery.After posterior reduction combined with H-shaped bone grafting and spinous process replantation for all patients,visual analogue scale (VAS) was utilized to assess symptom improvement and Cobb' s angle and sagittal spinal canal diameter were measured to help assess the treatment outcome.Results Pain was apparently eased at a 24-month follow-up (range,12-46 months).Cobb' s angle improved from preoperative 43.56° to postoperative 8.23° (t =1.33,P ＜ 0.01).CT findings showed mean spinal canal stenosis rate was 56.3％ before surgery and that mean sagittal canal diameter of the injured spine was larger than that of adjacent segments at follow-up,with the mean ratio of 116.3％ (range,111.3％-120.3％).Rate of spinal canal stenosis was negative for all patients and posterior canal with bone grafts healed.Spinal cord injury improved at least one Frankel grade.Conclusion Posterior reduction combined with H-shaped bone grafting and spinous process replantation is worthy of clinical application,for the procedure can restore the fractured thoracolumbar spine and posterior canal structure,but also effectively avoid the iatrogenic spinal stenosis.
