Objective To observe the effect of tea polyphenols on proliferation, invasion and apoptosis of human thyroid papillary carcinoma cells (CGTH W-3) in vitro. Methods The effects of various concentrations of tea polyphenols on proliferation, invasion and apoptosis of CGTH W-3 cells were observed by MTT assay, plate scarification assay and flow cytometer, respectively. Results Tea polyphenols(50-400 mg/L) inhibited the proliferation of CGTH W-3 cells with dose-and time-dependent manners. The IC_50 of tea polyphenols to CGTH W-3 cells was 240 mg/L (1st day), 229 mg/L (3 rd day), 200 mg/L (5th day) and 118 mg/L (7th day). The cell free zoster which reflected the invasive ability was widened by tea polyphenols. The apoptosis percentage of CGTH W-3 cells incubated with tea polyphenols for 48 h was obviously increased, with 3.51% in control group, 12.61% with 100 mg/L tea polyphenols, 52.97% with 200 mg/L tea polyphenols and 70.79% with 400 mg/L tea polyphenols (all P

Objective To evaluate content validity and construct validity of International Classification of Functioning,Disability and Health(ICF)Core Set for patients with organ transplantation.Methods Patients with kidney,liver,heart,or lung transplantation were assessed with ICF Core Set questionnaire,Functional Independence Measure(FIM)and Barthel Index(BI).Content validity was evaluated with frequency and percentage of patients with a problem for each ICF category,while construct validity was evaluated with Spearman correlation between ICF categories with FIM and BI.Results A consecutive sample of 102 patients completed this study.In body functions,10 categories were reported as a problem by more than 30% of the patients,of which 22 categories correlated significantly with FIM or BI.In body structures,structure areas of skin(s810)were reported as a problem by 30% of the patients,of which 3 categories correlated significantly with FIM or BI.In activities and participation,3 categories were reported as a problem by 30% of the patients,of which 15 categories correlated significantly with FIM and BI.In environmental factors,8 categories were reported as a facilitator by 30% of the patients,of which 8 categories correlated significantly with FIM or BI.Conclusion The content validity and construct validity of ICF Core Set for patients early after organ transplantation were good.

A rat model of metabolic syndrome was induced by high glucose plus high fat diet and treated by tea polyphenols for 10 weeks.The results showed that the levels of fasting blood glucose,triglyceride,cholesterol,low-density lipoprotein cholesterol,and free fatty acid in tea polyphenols treatment group were significantly lower than those in control group(all P＜0.05),along with decreased TNF-α,IFN-γ,iNOS mRNA and protein expressions,and IL-1β protein expression in pancreatictissue (all P＜0.05).Under electron microscope,more secretory granules in islet beta cells and impoveddisorganization of cellular organ were shown in tea polyphenols treatment group compared with metabolic syndrome group.The results suggest that tea polyphenols are able to protect islet β cells against oxidative damage via inhibiting the production of inflammatory cytokines.

Objective To observe the effects of salmeterol/fluticasone on the bone metabolism and bone density of the patients with moderate COPD and whether the effects is relate with inhaled corticosteroid course. Methods Sixty pa-tients with COPD were divided into 2 groups by random digit table. Patients in experimental group (n=30) were given conven-tional therapy with salmeterol/fluticasone one inhale(bid) for continuously 12 months while patients in control group (N=30) were given conventional therapy without any glucocorticoid.The bone mineral density (BMD) of the femoral triangle in all patients were measured by DXA before therapy, 3 months and 12 months after therapy. At the same time, biochemical indi-cators that are correlated with bone metabolism include bone gla protein (BGP) and alkaline phosphatase (ALP) were mea-sured by radioimmunoassay. Results The BMD, BGP and ALP of patients in experimental group and in control group be-fore therapy, 3 month and 12 month after therapy were compared. There is no significant difference (P>0.05) between these two groups before therapy and after 3 month but significant difference was shown after 9 months (P<0.05). Conclusion Short period inhaling salmeterol/fluticasone in patients with COPD is safe. But long-term inhaling salmeterol/fluticason may lead to decline of the bone density in patients with COPD.

Objective To explore the effect of individual rehabilitation nursing guidance on the initiative of rehabilitation therapy of spinalcord injury patients. Methods 50 spinal cord injured patients were divided into conventional group (group A) and individualized group(group B). Group A was given conventional rehabilitation nursing guidance. Group B was given special rehabilitation nursing guidance consideringthe patients' and their families' requirement. Initiative of rehabilitation therapy was assessed between group A and group B beforeand 2 months after intervention. Results Group A had no significant increasing of initiative assessment score (P<0.05) 2 months, while theinitiative assessment score of group B increased significantly (P<0.01), even group B was better than group A (P<0.05) after the intervention.Conclusion Individual rehabilitation nursing guidance may facilitate to improve the initiative of SCI patients.

Objective To study the characteristics and differences of phonetic pronunciation between hearing-impaired and normal children in 4.5~5.5 years old groups. Methods Phonetic articulation of consonants and vowels were tested by three-grade assessors for 20 hearing- impaired children and 20 normal children in 4.5~5.5 years old group using Question Bank for Hearing-impaired Children's Rehabilitation Evaluation of Hearing and Speech. Results and Conclusion For hearing-impaired children, the consonants of /b. m. d. l. j/ were the most articulative, followed with /h. f. r. p. t. n. g. x/, and then /zh. z. k. c. sh. q. s. ch/; for normal children, the consonants of /b. p. f. g. m. d. h/ were the most articulative, followed with /k. j. x. t. r. l/, and then /q. zh. ch. sh. n. z. s. c/. For both groups, the single final was the most articulative, followed with the compound final, and then the nasal. The articulation of these 3 types of vowels were poorer in hearing-impaired children than in normal children (P<0.01)

Objective To explore the value of Helicobacter pylori( Hp) drug sensitivity test for clinical treatment of Hp infection and peptic ulcer. Methods Selected from February 2013 to October 2014 gastroenterology clinic in the hospital inpatient treatment and 120 patients( Steering Group) , of which 69 cases of gastric ulcer, duodenal ulcer 51 patients, mucosal lesions in patients took tissue culture Hp, Hp strain cultured to antibiotic susceptibility testing by disk diffusion method and based on susceptibility testing to guide treatment , alternative 120 cases of peptic ulcer patients as a routine group, ulcer treatment effect was observed between two groups and Hp eradication therapy.Results Steering group of 120 patients, 75 patients were successfully cultured Hp, susceptibility test results: the most sensitive to gentamicin(94.67%), followed furazolidone(88.00%), the lowest sensitivity to metronidazole(8.00 %);reviewed 4 weeks after treatment, ulcer healing rate of steering group of patients 93.33% was significantly higher than the end of treatment 4 weeks after the ulcer healing rate of regular group of 81.67%, steering group of patients with abdominal pain short time (3.5 ±1.5)d was significantly shorter than conventional group of patients(4.3 ±1.7) d; Hp eradication of steering group patients was 89.17%significantly higher than conventional group were 78.33% and the difference was statistically significant ( P<0.05 ) .Conclusion According Hp susceptibility testing, can choose Hp sensitive proton pump inhibitor combination of antibiotics amoxicillin treatment, can achieve more significant clinical effect.

Objective Reviewing the experience in the diagnosis and treatment of cases with aorta-pulmonary septal defect and aortic origin of right pulmonary artery complicated with interruption of the aortic arch. Methods Reviewed clinical data from medical records for5 patients (4 boys and 1 girl, age from 1 to 18 years on admission) who had been treated in Wuhan Asia Heart Hospital between 2005 and 2009. Results All cases had type A interruption of the aortic arch ( according to Celoria and Patron's Classification) , type Ⅱ aorta-pulmonary septal defect( according to Mori Classification) and aortic origin of right pulmonary artery complicated with interruption of the aortic arch. Large patent ductus arteries were observed in all cases,and no cardiac abnormality such as ventricular septal defect was found. All patients received echocardiography and spiral CT examination, and 3 of them over 10 years of age received cardiac catheterization and angiography for the evaluation of the pulmonary artery pressure. Two patients, at the age of 14 and 18 years, had severe pulmonary hypertension and declined to receive the operation. One of the 2 cases had hemoptysis and was given prostacyclin ( Iloprost solution for inhalation, a drug for pulmonary artery hypertention ) for reducing the pulmonary pressure. The patient now has an improved cardiac fu0ction without recurrent hemoptysis. One 14-year-old case gave up the operation because of the financial problem and failed to communicate with us after discharge. Radical surgery was performed in the remaining three cases, one had serious infection in the lung and died 11 days after the operation, in one case ( 2 years old) pulmonary artery hypertension has been persisted even though drug therapy was given for a long time and was found at a poor cardiac function 18 months after the operation. One patient recovered well under routine drug therapy and has been followed-up. Conclusion Aorta-pulmonary septal defect and aortic origin of right pulmonary artery with interruption of the aortic arch ( with intact ventricular septum) are different from the classic triad of inter ruption of the aortic arch, consisted of the interruption of the aortic arch, patent ductts arteriosus and ventricular septal defect.It should be considered as a special kind of cardiovascular malformation syndrome. Echocardiography can be used for the preliminary diagnosis of aorta-pulmonary septal defect and aortic origin of right pulmonary artery with interruption of the aortic arch. The final diagnosis and decision for surgery should be based on the combined information from cardiac catheterization,cardiovascular angiography and spiral CT examination. Pulmonary artery pressure and resistance are the most important factors,because they have great effects on the duration of surgery and the outcome. A radical operation is necessary for all cases, but the mortality rate is high. The prognosis would be great if only the patient can survive successfully during the peri-operative period, a period with a poor cardiac function, potential lung infection and the pulmonary artery hypertension.

Objective To investigate the association of single nucleotide polymorphisms(SNP)in p21and p27 genes with the risk of epithelial ovarian cancer(EOC).Methods Genotypes were analyzed by polymerase chain reaction-restrictive fragment length polymorphism(PCR-RFLP)method in 234 patients with EOC and 284 control women in China.Results (1)The frequencies of the p21 in healthy controls were 34.2%.49.6%and 16.2%,while the distribution of the C and T allele was 59.0%and 41.0%,respectively.The p21 C/C(28.2%),C/T(53.0%),T/T(18.8%)distribution in ovarian cancer patients was not significantly different from that in healthy controls(P＞0.05).There was no statistic difference in allele distribution between ovarian cancer patients and healthy controls(P＞0.05)either.The stratification analysis by tumor histological type did show that the genotype distribution in four types of ovarian cancer patients was significantly different from that in healthy controls(P=0.02).The C/C genotype was likely to reduce the risk of epithelial endometrial cancer.and the adjusted odds ratio was 0.56(95%CI:0.32-0.98).(2)The genotype frequencies of the p27 in healthy controls were 88.4%,10.9%and 0.7%.while the distribution of the V and G allele was 93.8%and 6.2%.respectively.The V/V(93.6%),V/G(5.1%)and G/G(1.3%)distribution in ovarian cancer patients was significantly different from that in healthy controls(P=0.04).There was no statistic difference in allele distributionbetween ovarian cancer patients and healthy controls(P＞0.05).Compared with the V/G and G/G genotypes,the V/V genotype increased the risk of EOC,the adjusted odds ratio was 1.92(95%CI:1.02-3.63).Conclusion The C/C genotype of p21 may reduce the risk of epithelial endometrial cancer,and the genotype of p27 V/V may be a potential risk factor for susceptibility to EOC.
