Hypothyroidism is a common endocrine disease.Its treatment depends on thyroid hormone replacement therapy.Currently,levothyroxine (L-T4) is the preparation recommended by many guidelines.However,there are some L-T4-treated patients with normal TSH levels and persistent non-specific symptoms and discomforts.Therefore,combination therapy with L-T4and liothyronine (L-T3) has been considered as an alternative option for hypothyroidism.However,more prospective studies are needed to provide evidence-based effects for this kind of regimen.

Objective To describe the prevalence and distribution of anxiety disorders among people aged 18~65 yrs in Liaoning Province. Methods 15 518 subjects in 7 200 families aged 18~65 yrs were randomly selected from 3 cities and 3 counties by multi-stage stratified random cluster sampling.They were assessed for DSMⅢ-R diagnoses by face to face interview with Composite International Diagnostic Interview(CIDI-1.0). Results There were 13 359 subjects had finished the survey,and the response rate was 86.09%.The 2-week,12-month and lifetime prevalence of anxiety disorders were 2.22%,4.60% and 7.21% regulated by Liaoning provincial population in 2000,and1.91%,3.97%and6.32% regulated by countrywide population in 2000.The major disorders were specific phobia and agoraphobia,and their lifetime prevalence were 3.80% and 3.04%,respectively.The people with higher prevalence were females,aged 25~55,with lower educational and economic level. Conclusion Anxiety disorders become a serious public health problem in Liaoning province.Prevention measures should be taken among people with high risk.

Objective To evaluate the application of intra-operative cholangiography in cholecystectomy. Methods A total of 442 patients with biliary calculi underwent cholecystotomy were reviewed. Results Of the 442 cases, 3 were false positive and 1 was false negative radiologically. The accuracy rate was 99.1%. Conclusion The results suggested that the application of intra-operative cholangiography could decrease the incidence of residual calculi and avoid unnessary exploration and trauma of the common bile duct.

Objective:To study the direct medical expenses for inpatients with Multiple Myeloma and explore its influencing factors. Methods:A total of 1386 hospitalization records were collected using the reimbursement claim database in Guangzhou City during the period from January 2009 to December 2011 , which covered the entire enroll-ees of Urban Employee Basic Medical Insurance ( UEBMI) and Urban Resident Basic Medical Insurance ( URBMI) . Multivariate logarithmic regression models were used to analyze the influencing factors of direct hospitalization costs. Results:During the period from 2009 to 2011 , the total costs of inpatients with Multiple Myeloma were 19319 . 16 , 17364. 76 and 21427. 44 Yuan, and the individual out-of-pocket cash payments were 7049. 37, 5216. 5 and 6475. 39 Yuan respectively. The major influencing factors on direct medical costs of inpatients with the aforesaid disease were identified to be age, health insurance type, hospital level and length of hospitalization. Besides, the proportion of drug expenses as per average occupancy rate among UEBMI and URBMI cases during three years were 61. 92% and 69. 22% respectively. Conclusion: The direct medical costs for inpatients with Multiple Myeloma are high and the medicine cost is the main component of total medical expenses. In addition, the economic burden is higher for patients with URBMI than for those with UEBMI for treating Multiple Myeloma.

Objective In human,both in vivo and in vitro,telomere shortening appears to be a major component of cell senescence and aging. However, gender specific human telomere shortening needs to be further characterized. Therefore our study is aimed at clarifying gender-dependent profiles of telomere shortening. Methods 123 peripheral blood samples were collected from healthy individuals of different ages. The mean telomeric restricted fragment (TRF) was measured using Southern Blotting with Dig-labeled probe. Results Distinguished dynamics profiles of telomere shortening were observed among different age groups. Conclusion The result indicates that there are gender specific dynamic profiles of telomere shortening. Therefore, the gender must be considered when an individual age is estimated by telomeric restricted fragment length assay.

Objective:To investigate the inhibitory effect of cytokine-induced killer cells (CIK) against implanted gastric cancer cells. Methods:Gastric cancer SGC-7901 cells were subcutaneously injected into the inguina of nude mice to establish gastric cancer model. The tumor bearing mice were randomly divided into CIK group and fibroblasts group,in which mice were subcutaneously injected with fluorescence dye SP-DiI labeled CIK and fibroblasts HFL-I cells,respectively. Distribution of CIK and HFL-I cells in different tissues of gastric cancer bearing mice were observed. Meanwhile,tumor volume was measured after different treatments and tumor inhibitory rate was calculated. Tumor necrosis areas in different groups were observed. Results:SP-DiI labeled CIK was mainly located in the gastric cancer tissues 10 d after injection,and was hardly detected at the injection sites,liver,spleen and lung tissues (P

OBJECTIVETo investigate the relationship between hormone sensitive lipase (HSL) gene polymorphism and aerobic endurance.
METHODSThe (CA)n repeats polymorphism genotypes in HSL intro 6 of 123 outstanding long distance runners and 127 controls of Han nationality in northern China were analyzed by PCR and Fluorescence labeled STR-genescan. Repeat polymorphisms were grouped according to segmentation point and alleles were divided into long or short chains. Chi-square test was used to analyze the frequency difference of allelic and genotypic between athlete and control groups.
RESULTS(CA) n repeats polymorphism in HSL gene was total of 9 different repeat number of alleles, which composed of 25 different genotypes. The chi-square test result showed that when compared short and long chain alleles split by 4, there was a significant difference (P <0.05) of genotype distribution in 5/10 km group compared with control. Compared the rest groups with control, there was no significant difference.
CONCLUSIONCompared short and long chain alleles split by 4, the LL genotype of (CA)n of HSL was associated with aerobic endurance and it might be a molecular marker of elite 5/10 km long distance runners.

Objective To study the effect of infrasound on the changes of expression of NMDAR1 in hipp- ocampal cells.Methods Eighty-eight male Sprague-Dawley rats were randomized into eleven groups:control group,90 dB/1 d,7 d,14 d,21 d and 28 d infrasound exposed groups;130 dB/1 d,7 d,14 d,21 d and 28 d infra- sound exposed groups.All the animals in the test groups were put in an infrasound field with 8 Hz,90 dB or 130 dB for 2 hours daily.Immunohistochemistry methods were used to detect the changes of intracellular expression of NMDARI in hippocampal cells.Methods The expression of NMDAR1 in hippocampus after the rats were exposed to infrasound of 8 Hz,90 dB SPL showed a procedure from reducing on the 1st day to rising on the 7th and peaked on the 14th day,then to descending on 21st day and returning to the standard level on the 28th day.Exposure to infra- sound of 8 Hz,130 dB SPL induced opposite effects on the expression of NMDAR1 compared with 90 dB SPL,which showed a process of increasing,descending,reaching to the lowest,then ascending and returning to the normal.The lowest expression of NMDAR1 occurred on the 14th day in every observed hippocampal area.Conclusion 8 Hz, 90 dB/130 dB infrasound induced certain reversible reaction in the expression of NMDAR1 of hippoeampal cells in rats,which may disturb their learning and memory function.
