microRNAs are small non-coding RNA molecules involved in almost every biological process.The advance in microRNAs has demonstrated the potential role to act as the cancer biomarkers as well as the target for cancer therapy.Parathyroid carcinoma is a rare malignancy without appropriate standards of diagnosis.This review elucidates on some microRNAs which have been reported to be related to parathyroid carcinoma.

Purpose:To investigate the relation between the expression of cyclinB1 gene and drug resistance in patient with acute leukemia. Methods:Cyclin B1 gene mRNA expression in 13 cases of drug resistant and 14 drug non-resistant acute leukemia patients’ peripheral blood have been determinated by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR).The expression of mdr1 gene mRNA in these patients was measured with fluorescence -quantitative reverse transcription-polymerase chain reaction (RT-PCR). Results:The expression of cyclin B1 mRNA in the drug resistant group was significantly higher than the drug non-resistant group cyclin B1 mRNA (P

ObjectiveTo explore the characteristic and difference of the executive function of the premeditated group and attack group of male juvenile delinquents by the Stroop test.Methods 123 male juvenile delinquents and 128 normal controls were examined by a general information questionnaire,the Stroop test of the Chinese version and impulsive premeditated aggression scale (IPAS).SPSS17.0 statistical software used to analysis the survey results.Results ( 1 ) By Stroop test the premeditated group and impulsive group of juvenile delinquents was found that correct number of test 3( 109.97 ± 1.87),errors number of test 4(4.45 ±4.84),amend number of test 1 and test 4 ( 1.18 ± 1.50 ; 1.50 ± 1.59 ),and completion time of test 4 ( 143.74 ± 28.36) had statistically significant (P ＜ 0.05 ),the others had no significant difference between the two groups.(2) The premeditated group of juvenile delinquents and normal adolescents in Stroop test comparison was statistically significant in completion time of test 1,test 2 (56.49 ± 14.90 ;88.31 ± 20.02)(P ＜ 0.05 ).The impulse group of the juvenile delinquents and normal adolescents was statistically significant in the correct number of test 2 to test 4( 107.20 ± 3.39 ; 109.97± 1.87 ; 102.47 ± 5.62 ),errors number of test 2 ( 1.86 ± 2.27 ),amends number of test 3 ( 1.50 ± 1.59 ),and completion time of test 1 to test 4 (59.96 ± 11.08 ;92.03 ± 20.87 ;62.77 ± 12.31 ; 143.74 ± 28.36) (P ＜ 0.05 ).The others of two groups were no significant difference.ConclusionIt is found that juvenile delinquents exist defects of executive function,and perform functional defects in the attack group of juvenile delinquents is more obviously.

Objective To observe the effect of atropine and N-nitro-L-arginine methyl ester (L-NAME) on the pressure of lower esophageal sphincter (LESP) regulated by electro-acupuncturing (EA) at Zusanli acupoint (He-Sea, st 36) of stomach meridian and explore the neural mechanism of EA. Methods Forty-eight rats were divided into six groups:control group, EA group, atropine group, atropine+EA group, L-NAME group and L-NAME+EA group. LESP was observed and recorded by using three-channel perfusion manometric measurement system. Results LESP increased significantly under or after EA at Zusanli acupoint. Cholinergic M receptor blocker partly abolished the influence of EA on LESP, but EA could restore the decreased pressure of cholinergic M receptor blocked rats. Nitric oxide synthase (NOS) inhibitor increased LESP, and EA could make it higher. Conclusions The main efferent pathway of regulating effect of EA at Zusanli acupoint on LESP is via the chlinergic nerve of vagus, and other mechanism possibly exits.

Participating in the international conferences helps to get the latest progress in cer-tain areas. It provides important channels of communication and platform for cooperation. The article summarized the categories of international conferences, access to it, way to apply for it, how to apply for financial support, visa and passport, as wellas preparations before. The author's experience attend-ing the seventh Asia-Pacific conference neurochemistry(APSN) held in Singapore, may offer some help for reference.

Rough set is a mathematical approach to study imprecise, uncertain or incomplete information or knowledge. The data mining technology based on the rough set theory can be trained through the training data set. The technology is applied to such fields as the prognosis of the pain in the chest, emergence diagnosis in ICU, distinguishing and diagnosis of lung tumor and rheumatoid disease, diagnosis of galactophore disease, diagnosis of premature birth, classification and diagnosis of liver disease and acute appendicitis. The technology has a brilliant future in medical data mining.

Objective To study the pharmacological activity of soybean stem soyasaponin. Methods Normobaric hyporia and exhaustive swimming in mice and osteoporosis rats model were used to observe the pharmacological effects of soybean stem soyasaponin. Results Soybean stem soyasaponin 150 mg/kg significantly prolonged the survival time in hyporia and the swimming time of mice and 100 mg/kg in rats improved the syomptom of osteoporosis models. Conclusion Soybean stem soyasaponin has obvious effect on anti-exhaustion and increasing tolerance of oxygen deficit in mice and significant therapy effect on osteoporosis rats.

Objective To investigate the intelligence, individuality and behavior characteristics of epilepsy children with sub-clinical seizure. Methods The intelligence, individuality and behavior characteristics of the patients and normal age-matched children were evaluated by WISC, EPQ and CBCL. Results Compared with normal age-matched children, the code and number of WISC were obviously decreased in the children with epilepsy (P

The dynamic changes of the functions and the weight index of the 2 ventricles and the density of ?-adrenoceptors in the myocardium were observed and the correlation between the changes of ?-adrenoceptors of the myocardium and.the peripheral lymphocytes was investigated during and after intermittent chronic hypbxia in rabbits.The fingings were as follows.(1)Chronic hypoxia resulted in an increase of systolic pressure,dp/dtmas and weight index of the right ventricle.25 days after the restoration of normal oxygen supply,systolic pressure and dp/dtomas of the right ventricle became normal but its weight index remained increased.(2)The density of ?-adrenoceptors of the 2 ventricles was reduced on the 7th,15th and 30th day of hypoxia as compared with that of the control.25 days after the restoration of oxygen supply,the density of ?-adrenoceptors became normal in the left ventricle but remained decreased in the right ventricle.(3)There was a positive correlation between the changes of ?-adrenoceptors in the 2 ventricles and peripheral lymphocytes.The findings suggest that hypoxia-induced hypertrophy of the right ventricle is usually accompanied with a decreased density of its ?-adrenoceptors and thedensity of ?-adrenoceptors of peripheral lymphocytes can reflect the changes of ?-adrenoceptors in the myocardium.

Aiming at the missing links in traditional models of ideological and political course in medical colleges of our country,we built the3+3+3model teaching paradigm,and selected students of medical laboratory and pharmaceutical profession as the research object to put this mode into practice.We issued questionnaires and test to evaluate teaching effect.The study showed that this model could make up for the loss of traditional teaching pattern,which verified the effectiveness and the significance of the teaching reform.The shortcomings as well as its future direction was also made clear.
