Objective To observe the variety of liver and kidney function during lung transplantation and discuss its reference value of diagnosis and therapy in clinical acute rejection(AR).Methods The variety of TBIL, ALT and CRE were dynamically studied and analyzed before and after lung transplantation in 2 cases shared one same donor's lung block.Results During the use of CSA,TBIL diversely procedurally raised and it got right when AR was under control; when illness was worsen,ALT abnormally raised and CRE had no remarkably change.Conclusion TBIL is the sensitivity index of hepatotoxicity of immunity inhibitor CSA after lung transplantation. The abnormal change of ALT is the index of disease turnover.

Objective:To study the effect of Rhizoma Coptidis apozem on expression of AMP-activated protein kinase(AMPK) in skeletal muscle of metabolic syndrome rats. Methods:The models were established by administering high fat diet. Rats were randomly divided into five group: normal control group, metabriolic syndome group, Rhizoma Coptidis apozem group, Berberine group, Metformin group. To estimate insulin resistance by euglycemic hyperinsulinemic glucose clamp(GC) tecchnique. To estimate expression of AMPK by using Western blot. Results: Compared with metabolic syndrome group, Rhizoma Coptidis apozem group had higher M-value, lower wet weight of innards fat, and higher protein level of p-AMPK-?. Conclusion: Rhizoma Coptidis apozem can improve insulin resistance, decrease innards fat, and regulate up expression of AMPK.

Objective To probe into the strategies for improving the accessibility to orphan drugs for patients of rare diseases in China. Methods Analysis of typical cases of orphan drug use in recent years in China, interviews of hospital administrators and clinical doctors, and analysis of the present health insurance policies in China for orphan drugs, definition of the concept of drug accessibility, clarification of the factors hindering orphan drug accessibility. Results Four factors are found to hinder orphan drug accessibility in such aspects of science and technology, supply, information transfer and medical assurance in China's medicine and healthcare system. These subjective and objective factors affect drug accessibility of the patients of rare diseases, denying them of drug accessibility, of drug use in time, and of affordability of such drugs. Conclusion To raise the orphan drug accessibility in China, it is necessary to define basic concepts and incentive mechanism of rare diseases and orphan drug, design and raise the response mechanism of the medicine and health system in orphan drug supply, build a three dimensional cooperation model between such parties as the government, enterprise and patient, and reduce patients' economic burdern.

Objective To explore the reasonable radiotherapy range by analyzing the patterns and characteristics of intra-thoracic lymph node metastasis in small cell lung cancer (SCLC).Methods One hundred and fifty patients with limited-stage SCLC who received radical resection of primary tumor and systemic intra-thoracic lymph node dissection were included in the study.All the lymph nodes in each area were recorded and examined pathologically to analyze the patterns and characteristics of intra-thoracic lymph node metastasis.Results A total of 2372 lymph nodes were found in 631 areas,and a total of 413 positive lymph nodes (17.4％) were found in 188 lymph node areas (29.8％ ).Intra-thoracic lymph node metastasis were found in 88 patients,with a positive rate of 58.7％.The frequencies of metastasis in the area 11,10,7,5,4 were much higher than those in the other areas,and central located lesions and the higher T-stage lung tumors were more likely to develop intra-thoracic lymph node metastasis (x2 =15.32,39.72;P =0.000,0.000,respectively).Tumors located in the right upper lobe and right middle/lower lobe had a higher tendency of metastasis to the areas 4,7,10 and 4,7,10,11,respectively.Tumors located in the left upper lobe and left lower lobe had a higher tendency of metastasis to the areas 4,5,6,10 and 4,7,9,10,11,respectively.Mediastinal lymph node metastasis (N2 ) were found in 72 patients,among whom 29 patients (40.3％ ) had skipping N2 metastasis without hilar metastasis.Tumors located in the upper lobe had a tendency of skipping metastasis to the upper mediastinum,while tumors located in the middle/lower lobe had a tendency of skipping metastasis to the upper and lower mediastinum.Conclusions The lymph node metastases in SCLC follow the lymphatic drainage routes,that is,from intrapulmonary to the hilar and then to the mediastinum,but with some skipping metastases.Tumors located in different lobes have different high risk lymph node areas for metastasis,and elective irradiation to these lymph node areas maybe increase radiotherapy gain ratio in SCLC.

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.

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 evaluate clinical risk factors that can predict brain metastasis after complete resection of small cell lung cancer (SCLC) and to assess the role of prophylactic cranial irradiation (PCI) in such kind of patients.Methods Eighty-eight patients with completely resected stage Ⅰ - Ⅲ SCLC from Jan.2000 to Dec.2009 in our hospital were retrospectively analyzed.Kaplan-Meier was used to compare the differences in the incidence of metastasis free survival in different groups.Logistic model was used to assess the independent risk factors for brain metastasis.Results The follow-up rate is 100％,and 37 patients were followed up for more than three years.None of the 3 patients who received PCI developed brain metastasis,while for patients without receiving PCI,24％ developed brain metastases.The incidence of brain metastasis for stage Ⅰ,Ⅱ and Ⅲ SCLC after surgery were 4％,26％ and 29％ ( x2 =7.57,P =0.023),respectively.The median survival time and the 3-year survival rate were 18 months and 25％ for patients who developed brain metastasis,and 48 months and 59％ for those without brain metastasis ( x2 =10.63,P =0.001 ).Both univariate and multivariate analyses showed that pre-treatment disease stage wasindependent risk factor for brain metastasis ( x2 =7.57,8.52 ; P =0.023,0.004 ).Age,sex,tumor location,pathological type,induction chemotherapy,and postoperative chemotherapy/radiotherapy were not significantly correlated with the incidence of brain metastasis ( x2 =0.03,0.00,0.00,2.58,0.01,1.23,0.84;P =0.869,0.998,0.992,0.109,0.936,0.266,0.361,respectively).Conclusions Pre-treatment disease stage was independent risk factor for brain metastasis in SCLC.PCI may be important for stage Ⅱ -Ⅲ SCLC but not for stage Ⅰ disease.<英文关键词>=Carcinoma,small cell lung/surgery; Neoplasm metastasis,brain/prophylactic irradiation; Factors analysis
