In the embryonic period, myosin regulatory light chain (MYL2) plays a pivotal role in the development and function of the heart. A large number of studies have previously confirmed that the mutation of MYL2 gene, also known as MLC2, confers intimate associations with hypertrophic cardiomyopathy. MYL2 gene mutation impacts the structure and function of myosin, thereby leading to the occurrence and progression of hypertrophic and dilated cardiomyopathy as well as the following chronic heart failure. Importantly, MYL2 phosphorylation renders crucial effects in the processes of cardiac contraction, ventricular torsion and cardiac function.

Objective To compare the therapeutic efficacy and adverse effects between transcather arte-rial chemoembolization(TACE) and comprehensive therapy in primary advanced heptocellular carcinoma(HCC).Methods 216 patients with primary HCC were arranged randomly into two groups:104 (group A) were treated with TACE alone,the rest(group B)were treated with TACE combined with intraperitoneal perfusion chemothera-py, Chinese herbs and immunotherapy.The therapeutic efficacy and adverse effects were analysed and compared between two groups.Results The CR + PR rates were 28.84% in group A and 34.82% in group B.The 4-year survival rates were 1.92% in group A and 3.87% in group B(P < 0.05).There were no severe side effects in both groups.Conclusions The short-term effective rate and 4-year survival rate in comprehensive treatment group were superior to the control group.Therefore, the comprehensive treatment is worthwhile to use in primary advanced hepatocellular carcinoma.

BACKGROUND: Changes of physiological structure, changes of phenotype and first basic excision are all the changes of gene expression. The technique of DNA microarray is a new method to filtrate target genes fleetly and largely by using the theory of base-partnershin, which can holistically and magnificently study the expression and function of organics genes. OBJECTIVE: To study early differential expression genes of rats with cerebral hemorrhage with DNA microarray and establish academic foundation for exploring mechanism of cerebral hemorrhage.DESIGN: Randomized controlled research.SETTING: Department of Neurology, Affiliated Hospital of North Sichuan Medical College. MATERIALS: The experiment was conducted at the Affiliated Hospital of North Sichuan Medical College from October 2002 to December 2003. Twenty Wistar rats, of either gender, with body mass of 220-260 g, without special pathogen, provided by Experimental Animal Center of Chongqing University of Medical Sciences, were selected and randomly divided into control group and cerebral hemorrhage group, with 10 in each group. METHODS: Animal models with cute cerebral hemorrhage of rats were established with type Ⅶ collagenase tridimensional localization method,and 4 hours later tissues around hematom and normal cerebral tissue at the same part were detected with gene chip. Fluorescent signal was scanned with scanning apparatus and analyzed with computer. Result of genic expressive pattern was researched with reverse transcriptase-polymerase chain reaction (RT-PCR). MAIN OUTCOME MEASURES: Result of gene chip in cerebral tissue of rats and result of RT-PCR.RESULTS: Four hours after acute cerebral hemorrhage, 129 differential expression genes were screened out, in which there were 114 up-regnlation genes and 15 down-regulation genes. Those genes were mostly related to the following aspects: stress, immunological response, apoptosis, energy metabolism and signal transmitting. Genes related with inflammatory impairment were mostly obvious. The result of RT-PCR suggested that the level of genic expression was as the same as the result of Cdna chip, which indicated that genic expressive pattern based on gene chip had great reliability.CONCLUSION: Early cerebral hemorrhage has many differential expression genes, which can play an important role in hemorrhagic brain damage.

Objective To analyze the clinical features and evaluate outcomes of active pulmonary tuberculosis(TB)patients in floating population.Methods Retrospectively analyzed the clinical data of 68 active pulmonary TB patients in floating population,in comparison with 123 cases of TB patients of local which was treated as control group.Evaluated the outcomes by analyzing the composition of sex and age,tuberculosis type,positive phlegm germ.males and 33 females;so the male to female ratio was 2.73:1,the difference between two groups was statistically significant(x2=3.37,P＜0.05).The age in study group ranged from 18 to 62,the average was(30.23±18.52),and it ranged from 18 to 70 in control group,the average was(46.46±31.50),the difference between two groups was statistically significant(t=25.14,P＜0.05).Among those aged 21 to 30,the incidence in study group was 44.11%(30/68),and in control group it was 24.39%(30/123),the difference between two groups had statistical significance(x2=9.91,P＜0.05).In study group,there were 68 sputum smears,47 of them were positive,and the proportion was 69.11%;In control group,there were 123 sputum smears,70 of them were positive,and the proportion was 56.91%.The difference between two groups had statisticall significance.In study group.there were 22 patients who stopped by themselves accepting treatment,accounting for 34.92%;At same time,in control group,there were 23 patients who stopped by themselves accepting treatment,accounting for 18.67%.The difference of treatment compliance between two groups had statistical significance(x2=6.890,P＜0.05).After 6 months treatment,41 cases were treated in study group,of them 37 cases sputum bacterium turns negative,accounting for 90.24%;the same time 100 cases were treated in control group,of them 92 cases sputum bacterium turns negative,accounting for 92.00%.The difference of sputum bacterium conversion rate in two groups had no statistical significance(x2=0.1 10,P＞0.05).Conclusion The incidence rate of tuberculosis was high in floating population of Pinghu City.The TB patients in floating population could receive the same treatment as those in local population through DOTS treatment.

Objective To investigate the effect of CD147 monoclonal antibody (mAb) on the natural resistance to paclitaxel (TAX) in the human cervical cancer line (HCE1) multicellular spheroid (HCE1/MCS) model and if CD147 mAb can reverse the HCE1/MCS resistance to TAX. Methods HCE1/MCS was obtained by liquid overlay and rotating technique. HCE1/MCS morphological changes were observed before or after the interference of CD147 mAb. The effects of TAX on HCE1/MCS (including inhibition ratio, IC50 and index of multicellular resistance) before or after CD147 mAb treatment were determined by the method of WST-1 and the inhibition ratio curve was mapped. Cell cycle and apoptosis were detected by flow cytometer (FCM). The expression of CD147 and P-gp of both HCE1/MC and HCE1/MCS was detected by immunocytochemistry. Results HCE1/MCS was established successfully. CD147 mAb could inhibit HCE1/MCS from forming spheroids. CD147 mAb could enhance the sensitivity of HCE1/MCS to TAX. IC50 in different concentrations of CD147 mAb (5,10,20 μg/mL) HCE1/MCS group were (40.31±3.73), (32.43±1.56), and (30.69±1.01) μg/mL. CD147 mAb resulted in G1/G0 arrest in HCE1/MCS. CD147 mAb of low concentrations (0-10 μg/mL) caused a dose-dependent inhibition of HCE1/MCS (P<0.05). Combined with TAX, CD147 mAb could also induce HCE1/MCS cell cycle arrest in both G1/S and G2/M stage. The expression of CD147 and P-gp was consistent in HCE1/MCS groups. Conclusion CD147 plays an important role in muliticellular resistance of cervical cancer and inhibition of CD147 can synergistically reverse the multicellular drug resistance (MCR) in cervical cancer. The MCR of HCE1/MCS mediated by CD147 is related to P-gp.

The premature ovarian failure(POF) may be inherited as an X-linked condition.Among genetic causes,X monosomy or X deletions and translocations are known to be responsible for POF.The X chromosome disorders such as mutations of the human bone morphogenetic protein-15 gene,the zinc finger protein gene,the X-inactivation-specific transcript gene,the drosophila melanogaster diaphanous gene,the X 2 linked aminopeptidaseP enzyme gene,the fragile X mental retardation gene are associated with POF.
