Objective To compare the diagnostic value for hysteromyona with trans-abdominal ultrasound (TAS) and trans-virginal ultrasound(TVS). Methods Two empirical doctors detected respectively 82 patients by TAS and TVS in double blind method. The results were compared with pathological results. Result The correct rate of diagnosis in 82 patients with 123 hysteromyoma focus by TVS and TAS was 96.75% and 86.18% respectively.There was statistical difference between TAS and TVS. The correct rate of combining use of the two method was 98. 37%. Couclusion Either TVS or TAS had its own merit and defect, Combining use of the two method could raise the correct rate.

Objective To investigate the correlation between the severity of coronary artery disease with se-rum bilirubin and left ventricular cardiac function. Methods Two hundred and six patients underwent blood bio-chemical ,color-echocardiography and angiography of coronary artery. The patients were divided into 4 ordinal groups according to the Gensini score indicating the severity of coronary artery disease. Results There were significant differences in total bilirubin(TBIL), left atrial dimension (LAD), left ventricular dimension (LVD) and left ventric-ular ejection fraction (LVEF) between the four groups(P<0.05 or P<0.01). The Spearman correlation coefficent between Gensini's scores and LAD, LVD were 0.280 (P=0.000) and 0.176 (P=0.011), respectively. The Spearman correlation coefficient between Gemini's scores and TBIL, LVEF were -0.541 (P<0.000) and -0.222 (P=0.001), respectively. The multiple linear regression between the Gensini's score and parameters showed that TBIL and LVD were independently correlated with the Gensini scores (P=0.000 and P=0.002, respec-tively). Conclusions TBIL and LVD were independently correlated with Gensini's score. LVEF was negatively cor-related with the severity of coronary disease and is a useful predictor for the severity of coronary atherosclerotic heart disease.

Carboxysomes are extremely efficient microcompartments committed to CO2 fixation due to tailored CO2-concentrating mechanism (CCM). In cyanobacteria and some chemoautotrophs, carboxysomes as organelle-like microbodies encapsulate ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and carbonic anhydrase (CA). Together with active inorganic carbon uptake transporters, carboxysomes accumulate HCO3(-) in the cytoplasm, leading to high efficiency of carbon fixation. Based on the elucidation of structures and functionalities, heterologous production of carboxysomes has been achieved so far. In fact, the genes encoding either vacant carboxysome shell or only interior components have been characterized. This review summarizes the discovery along with types, showcases molecular structures and roles of carboxysomes in CCM, and presents their broad applications in metabolic engineering.

OBJECTIVE:To make clear the present status and developing trend of drugs used in enterprise hospitals and municipal hospitals in Chongqing between2001～2003to offer reference information for the departments concerned.METHO_ DS:The data of drugs used in enterprise and municipal hospitals in Chongqing were retrospectively analysed.RESULTS:In enterprise hospitals and municipal hospitals,the annual increasing rates of sales volumn of drugs were8.24%and18.29%;the anti-infectives accounted for40%～41%and36%～40%of annual sales volumn and sales volumn of imported drugs amounted to4.40%and14.78%of total drugs consumed respectively.CONCLUSION:The sales volumn of drugs in enterprise hospitals is decreasing year by year,while that in municipal hospitals is increasing.

New method of prostate cancer has grown more precise with the development of medical imaging.Multi-parametric MRI targeted biopsy and fusion biopsy reduce the cores,at the same time they have similar positive rates compared to systematic biopsy.The most used biopsy methods are still transrectal guided transrectal biopsy and transperineal biopsy in China.If we can predict biopsy result before the operation by physical and laboratory examination,it will help improve the detection rate and avoid repeating biopsies.And it has been indicated that age,tPSA,PSAD,fPSA/tPSA,PV,DRE,PHI and PCA3 are the predicting factors.Chinese Prostate Cancer Consortium Risk Calculator is fit for Chinses people.

Objective To analyze clinical efficacy and safety of left colon and bowel obstruction .Methods 80 cases of left colon and bowel obstruction were divided into the observation group and control group,40 cases in each group.The observation group was given a surgery,and the control group received two surgical treatment,the two groups were taken the statistical analysis of clinical data to compare the clinical efficacy and safety of operation. Results The operative time,hospital stay and surgical blood loss in the observation group was (42.9 ±13.8) min, (9.3 ±2.8)d,(45.9 ±11.7)mL,which in the control group were (58.6 ±17.6)min,(6.8 ±1.5)d,(151.4 ± 19.4)mL,there were statistically significant difference between the two groups(t=25.358,16.128,29.475,all P<0.05);The abdominal abscess,lung infections and wound infection incidence of adverse reactions in the observation group was 7.5 %,10.0%,20.0 %,which in the control group was 17.5 %,2.5%,10.0%,there were statistically significant difference between the two groups (t=4.512,4.336,4.762,all P<0.05).Conclusion The clinical treatment of left colon and bowel obstruction shall promptly conduct a surgery,the role of hospitalization in patients with shorter length to enhance tumor resection rate,and actively improve the quality of life of patients.

Objective:To investigate the expression of multidrug resistance (MDR1) gene and multidrug resistance-associated pro-tein (MRP) gene in patients with non-small-cell lung cancer (NSCLC) and its relation to histopathological type. Methods:The MDRi and MRP genes were determined by reverse transcription-polymerase chain reaction (RT-PCR) in 48 NSCLCspecimens. Results:The positive rates of the MDR1 and MRP gene expression were 62.5％ and 66.7％ respectively in the48 patients. Twenty-one of the 48 NSCLCs (43.8％) expressed both MDR1 and MRP genes. The positive rates of the MRPgene expression in squamous cell carcinoma was significantly higher than those in adenocarcinoma (P＜0.01), and therewas no significant difference in MDR1 gene expression between the two groups (P＞0.05). Conclusion: The MDR1 andMRP gene expressions were both or respectively in the NSCLCs. The incidence of the MRP gene expression in squamous cellcarcinoma was higher than that in adenocarcinoma.

Objective To investigate the effect of ademetionine assisted therapy on transferrin ( TRF) , myocardial enzyme spectrum and bilirubin in serum of patients with icterus neonatorum.Methods 86 cases of neonatal jaundice in the hospital were randomly divided into two groups.43 cases in control group were treated with conventional therapy, 43 cases in experimental group were treated by ademetionine.Serum transferrin, myocardial enzymes, serum total bilirubin levels and clinical effects were compared pre-treatment and post-weat ment.ResuIts Compared with control group, the TRF level of experimental group was higher (P<0.05), the level of Aspartate transaminase (AST), lactate dehydrogenase (LDH), creatine kinase (CK), and CK-MB in experimental group were lower (P<0.05), the total bile acid (TBA), total bilirubin (TBIL) and direct bilirubin (DBIL) in experimental group were lower (P<0.05).The total effective rate in experimental group was significantly higher than that in control group (χ2 =8.53, P<0.05).ConcIusion Ademetionine assisted therapy has a good clinical curative effect and could effectively reduce serum TRF, DBIL and myocardial enzyme spectrum level, which has important significance in the treatment of neonatal jaundice.
