Objective To investigate the association between the genetic polymorphisms of vitamin D receptor(VDR)and bone mineral density (BMD) in elderly male patients with chronic obstructive pulmonary diseases. Methods Pulmonary function, body mass index(BMI), serum calcium, serum phosphorus and bone glaprotein were determined respectively in COPD group and control group. In the two groups the VDR gene polymorphisms were analyzed by polymerase chain reaction and restriction fragment length polymorphism (PCR RFLP) and BMD were investigated by dual energy X ray bone mineral density. Results There were differences in BMD, BMI and bone glaprotein between the two groups. The BMI, bone glaprotein and BMD of femur neck in COPD group were(22 65?3 18)kg/m 2 ,(2 50?0 57) ?g/L and(0 75?0 13)g/cm 2 respectively, which were more decreased than those in control group: BMI (24 86?3 68)kg/m 2 , bone glaprotein (2 87?0 61) ?g/L and BMD of femur neck (0 86?0 12) g/cm 2 ( P

Objective To explore the diagnostic value of 18F-FDG PET/CT in primary peritoneal papillary serous carcinoma (PPPSC).Methods Ten postmenopausal female cases of pathologically diagnosed PPPSC from March 2009 to October 2011 were retrospectively reviewed (age range:61-81 years,mean:(69.4±6.2) years).All cases underwent 18F-FDG PET/CT.The CT characteristics and SUVmax of lesions on PET images were analyzed.Serum CA125 levels were measured before or after PET/CT within one week.The patterns of PPPSC on PET/CT were compared with histopathological results.Linear correlation analysis was used to evaluate the correlation between the CA125 and the maximum SUVmax of lesions presented in parietal peritoneum,greater omentum or mesentery.Results The PET/CT uptake pattern of the 10 PPPSC cases was described as floccus,multi-nodular or cake-like in greater omentum (SUVmax =6.32±2.87),and as diffuse or localized nodules,or non-uniform strip-like thickening in 9 parietal peritoneum and 8 mesentery cases (SUVmax =5.96±2.14 and 5.70± 1.69,respectively).The most commonly involved sites were pelvic wall of peritoneum and mesentery of small intestine.All 10 cases had different degrees of ascites,mainly intrapelvic and perihepatic.Hypermetabolic ovarian enlargement (all ＜5 cm) was bilateral in 2 patients and right-sided in 1 patient.Four patients had retroperitoneal lymph node metastasis and others were found with punctate calcifications in metastatic lymph nodes,small pleural effusions,liver metastasis,as well as portal node metastasis.CA125 concentration was elevated in all cases ((51.25±26.40) ×104 U/L),but there was no significant correlation between CA125 and the maximum SUVmax of lesions found in parietal peritoneum,greater omentum or mesentery (r=0.05,P＞0.05).Conclusion 18F-FDG PET/CT could show the positions and metabolic status of PPPSC lesions.It may be an effective imaging modality in the diagnosis and assessment of PPPSC.

Objective Gene linkage would be processed in order to make sure if an autosomal dominant congenital hyperthyroidism family has genetic linking relationship with the known hyperthyroidism disease genes,TSHR or THRB.Methods Microsatellite marked gene linkage was done with the use of three microsatellite markers,D14S74,D3S2338 and D3S1266,whose chromosomal locations were very close to TSHR or THRB gene,and the results were analyzed by Genemapper 3.5 Software.Results LOD scores of the three markers were all less than 1,revealing that there were no linking relationships between TSHR or THRB gene and this hyperthyroidism family,further reflecting this family might have a new disease gene other than TSHR and THRB.Conclusion There might be new disease genes responsible for autosomal dominant congenital hyperthyroidism.

Objective To explore the association between ankylosing spondylitis(AS)with the poly- morphism in -308 site of tumor necrosis factor(TNF)-?promoter region. Methods The literature about AS and polymorphism in -308 site of TNF-?promoter region were searched and the meta analysis as performed. Results Eight studies enrolled 987 AS patients and 922 controls in total. The analysis showed that the fre- quencies of alleles and the genotypes had no statistical difference between AS group and the control group [OR=0.86(0.53, 1.38), P=0.53; OR=0.90(0.52, 1.55), P=0.69]. But the frequencies of alleles of western origin had statistical difference between AS group and the control group [OR=0.75(0.59, 0.96), P=0.02]; The TNF-?gene promoter polymorphism may play a role in the severity of sacroiliitis[OR=0.37(0.15. 0.90), P=0.03]. Conclusion The meta-analysis reveales that the alleles of -308 site of TNF-?promoter region may be associated with AS in western ethnical group and play a role in the severity of saeroiliitis.

Objective To investigate the effects of ultraviolet blood irradiation and oxygenation(UBIO)on oxygen free radical metabolism(OFRM)in rabbits with acute soman intoxication.Methods One hundred rabbits were randomly divided into five groups:a control group,a soman intoxication group(I),a soman intoxication plus routine therapy group(TR),a soman intoxication plus UBIO therapy group(UBIO)and a soman intoxication plus complex therapy group(CT).All the rabbits were intervened accordingly.Then the concentrations of malondiade- hyde(MDA)and the activities of superoxide dismutase(SOD),glutathionperoxidase(GSH Px)and catalase (CAT)in serum were determined at 14 d after various treatments.Results Compared with the control group,the concentration of MDA and the activity of CAT in the 1 group were significantly increased(P＜0.01),while the activi- ties of SOD and GSH Px were obviously decreased(P＜0.05).After UBIO or complex therapy,the serum level of MDA was significantly decreased in comparison with that in the I group(P＜0.01),while the concentrations of SOD, GSH Px and CAT were enhanced(P＜0.05).Conclusion UBIO therapy can improve antioxidation activity against the injury caused by free radicals and could be used to treat acute soman intoxication,which causes injury from in- creased oxygen free radical concentrations.

Objective To find out the iodine nutritional status of Longyan downtown residents,evaluate the effectiveness of control measures and provide a scientific basis for developing control strategies.Methods Infants aged 0 to 2 year-old,children aged 8 to 10,adults aged 18 to 45 and pregnant and lactating women were selected as survey subjects.Children goiter was detected with B ultrasound.Residents per capita daily salt intake was investigated by weighing method.Three urinary samples and a milk sample of lactating women were randomly collected.Urinary iodine and milk iodine content were determined by arsenic cerium catalytic spectrophotometric assay.Blood samples were collected and thyroid function (including serum TT3,FT3,TT4 and FT4) and thyroid stimulating hormone(TSH) were measured with direct chemiluminescence immunoassay,and thyroglobulin antibody(TgAb),thyromicrosome antibody(TMAb),and thyroglobulin (Tg) were measured with radioimmunoassay (RIA) in serum.ResultsThe goiter rate of children aged 8 to 10 was 1.8％ (2/110),and median thyroid volume was 2.75 ml.Household iodized salt coverage rate was 100.00％(318/318),and qualified iodized salt was 94.03％ (299/318).The daily per capita salt intake was (6.13 ± 3.56)g.The average medians of urinary iodine of the infants,children,adults,pregnant and lactating women were 181.8,315.2,196.6,158.7,136.4 μg/L,respectively.The median of milk iodine of lactating women was 155.6 μg/L.The proportions of serum TT3,FT3,TT4,FT4 and TSH which higher than normal were 3.6％ (11/308),0.6％ (2/309),23％ (7/309),1.0％ (3/313) and 1.3％ (4/312),respectively.While the proportions of serum TT3,FT3,TT4,FT4 and TSH that lower than normal were 2.3％ (7/308),11.7％(36/309),2.3％(7/309),12.8％(40/313),and 1.6％(5/312),respectively,of which 16 cases of both TgAb and TMAb were higher than normal.ConclusionsExisting salt iodine level is appropriate for 0 to 2 year-old infants and young children,18 to 45 year-old adults,pregnant and lactating women in downtown Longyan city.The iodine intake of children aged 8 to 10 is excessive.Thyroid function monitoring is recommended to be included in the routine monitoring.

OBJECTIVETo evaluate whether the self-blood has influence on the molding process of polymethyl methacrylate (PMMA) bone cement, and to make sure whether it is valuable for the clinical practice.

METHODSAn in vitro study was performed to evaluate the prolonging-effect of self-blood on PMMA bone cement. The effect of prolonging was evaluated by the dough time (TD) and operable time (TO). Moreover, hardness test, squeezing value test and peak temperature test were also conducted to complete the evaluation of this program.

RESULTSThe self-blood, especially the plasma, could greatly prolong the handling time of PMMA bone cement without affecting its basic characteristics including hardness, leakage level and peak temperature. On the other hand, we found that in some abnormal conditions, for example with hyperlipemia, self-blood though can also prolong the handling time, would cause some side-effects.

CONCLUSIONWe report a new effective way to prolong the handling time of PMMA bone cement by adding moderate amount of self-blood. But "individualized medicine" should be noticed because some abnormal conditions like hyperlipemia would cause undesired side-effects.

Camptothecin is a strong anti-tumor compound isolated from Camptotheca acuminata. One of the most important way for the production of Camptothecin is by cell cultures of Camptotheca acuminata. The effect of Cu2+ on camptothecin accumulation in Camptotheca acuminata cell line was described in this paper. The results showed that the optimum CuCl2 concentration in B5 medium was 0.008 mg/mL, which increased camptothecin production for 30 times compare to the control while has no inhibitive effects on cell growth, at the same time, the peroxidase activity was increased and the anthocyanidin accumulation was inhibited. The promotive effects of Cu2+ on camptothecin accumulation in light was higher than that in dark.
