Objective To study the clinical characters,diagnosis and principles of treatmentof acute pancreatitis during pregnancy.Methods Forty-eight cases of acute pancreatitis during pregnancy treated in the recent 8 years were retrospectively analyzed,38 cases had non-surgical treatment(of which 36 cases were cured);10 cases had surgical treatment to remove necrotic tissue and mainly termination of pregnancy.Results Most of the cases in this group had simple pancreatitis,which accounted for 64.58%(31/48).There were 5 cases of maternal(10.42%) death and three cases of fetal(6.25%) death,and all were in patients with severe pancreatitis.Fatality rate of pregnant women with severe pancreatitis was 29.41%.Conclusions Acute pancreatitis during pregnancy is a serious disease with low prevalence rate,but has high fatality rate,and is the primary cause of death in acute abdomen of pregnancy.Nonoperative treatment is the first choice of treatment in this condition.In severe cases,timely surgical intervention is warranted,and the surgical indications should not be altered because of the pregnancy.The safety of both the pregnant woman and the fetus must simultaneously be kept into mind during therapy.

Objective To understand the gene carrying rate ,gene mutation types and distribution characteristics of thalassemia in the northeast area of Chongqing .Methods 28 633 specimens collected from the patients and individuals with physical examina‐tion in our hospital from January to December 2013 were performed the RBC parameters detection and hemoglobin electrophoresis screening .The specimens with phenotype positive were definitely verified the thalassemia type by using Gap‐PCR and reverse dot blot(RDB) .Results Among 28 633 specimens ,1 358 specimens were finally diagnosed as thalassemia with the thalassemia carrying rate of 4 .74% ,including 589 cases(2 .06% ) of α‐thalassemia and 741 cases (2 .59% ) of β‐thalassemia cases .Among the α‐thalasse‐mia genotypes ,‐αα/‐‐SEA genotype(1 .38% ) was most common ,the next was ‐αα/‐α3 .7 genotype (0 .37% ) and αα/‐α4 .2 genotype (0 .20% ) .Among the β‐thalassemia genotypes ,CD41‐42 genotype (1 .27% ) had the highest constituent ratio ,followed by IVS‐2‐654 genotype(1 .27% ) and CD17 genotype(0 .30% ) .28 cases were found to be the double heterozygote with α‐thalassemia and β‐thalassemia .Conclusion The northeast area of Chongqing is a region with the high incidence rate of thalassemia and complicated heredity .Therefore this research provides the reference information for the prevention of thalassemia ,genetic counseling and prena‐tal diagnosis .

0.05).Conclusion The PAI-1 genotype perhaps may not be one of independent risk factors for both T2DM and FA-IMT in T2DM patients.

Polymeric micelles have exhibited attractive properties as drug carriers, such as high stability in vivo and good biocompatibility, and been successfully used to dissolve various drugs of poor aqueous solubilities. In this study, we developed a new type of polymeric micelles with mannose-mediated targeting and pH-responsive drug release properties for anticancer drug delivery. The polymeric micelles were prepared from an amphiphilic polymer, poly (glycidyl methacrylate)-g-mannose (PGMA-Mannose). An anticancer drug, doxorubicin (DOX), was encapsulated into the micelles during the micellization, and could be released rapidly under acidic condition. The specificity of cellular uptake of the micelles by two different cell lines was studied using confocal laser scanning microscopy and the MTT assay. DOX-loaded micelles were efficiently trapped by mannose-receptor-overexpressing cancer cells MDA-MB-231, whereas mannose- receptor-poor cells HEK293 showed much lower endocytosis towards the micelles under the same conditions. Thus, DOX-loaded micelles displayed higher cytotoxicity to MDA-MB-231 cancer cells as compared with free DOX. The present study demonstrates that PGMA-Mannose micelles are a promising targeted drug delivery system for cancer therapy.

Objective To know the changing characteristics of residents' iodine nutritional status after eating salt with different iodine concentrations in Hubei Province,according to the assessment standard of iodine nutrition recommended by WHO/UNICEF/ICCIDD provide a scientific standard for appropriate iodine concentration in edible salt.Methods According to inhabitants' salt and urine surveillance of Hubei in 2010,Xinzhou District,Tianmen City and Changyang County were selected for trial.Salt with two kinds of iodine content was used in 3 trial areas in 4 months for the study of community intervention.Before the intervention,3 months and 4 months after the intervention,urine samples of observed participants(40 from 8-10 old children,40 from pregnant women or lactating women and 40 from adults aged older than 18) were collected and tested.The urinary medians of different groups of people and at different times were calculated and compared.Results Three months and 4 months after the intervention,in those towns using iodized salt of (15 ± 3) mg/kg,the urinary medians of children,declined from 294.2 μg/L to 185.6,195.7 μg/L,respectively.The urinary medians of pregnant women or lactating women dropped from 269.0 μg/L to 141.7,176.1 μg/L.For adults aged 18 and older,the urinary medians changed from 304.9 μg/L to 199.7,202.2 μg/L.In those trial towns of using (25 ± 3)mg/kg iodized salt,the urinary medians of children,pregnant women or lactating women and adults older than 18 all went down from 301.1 μg/L to 229.7,253.8 μg/L,from 261.4.0 μg/L to 196.6 and 206.5 μg/L and from 379.7 μg/L to 244.3,237.4 μg/L,respectively.Conclusions According to the assessment standard of iodine nutrition recommended by WHO/UNICEF/ICCIDD and the decreasing of urinary iodine median and per capita daily salt intake,salt with 25 mg/kg iodine is suitable as the average level of salt iodine concentration after the adjustment in Hubei Province.

Objective To evaluate the treatment of hypervascular hepatic metastasis with TACE. Methods One hundred and twenty nine cases of hepatic metastasis treated by TACE were selected retrospectively and then analyzed the survival rate,clinical effectiveness and lipidol deposition quantity in tumor.Results Malformation of tumor vessels and rich blood supply were found in all cases of this study.The survival rates of 6 months,1 year and 3 years were 100%,73.6% and 26.4% respectively.The clinical effective rate was 68.2%(88/129)and no-progress rate was 23.3%(30/129).The satisfactory lipidol deposition quantity was obtained in 80.9%(97/129).Conclusions TACE is a favorable method for hepatic metastasis,and discerning the hypervascular subgroup could improve the treating effectiveness and be useful to make an appropriate planning.

?ig-h_3 was first identified as a transforming growth factor-beta1-inducible gene in human lung adenocarcinoma cell line. It encodes for a secreted extracellular matrix (ECM) protein, which is thought to act on cell attachment and ECM composition. Previous study showed that ?ig-h_3 were highly expressed in human hepatoma cell lines and lowly expressed in human normal hepatic cells. The present study aimed to transfect ?ig-h_3 into 7721 cells to investigate its effect on secretion of MMPs in the transfected human hepatoma cells. Full-length ?ig-h_3 gene,cloned by reverse transcription polymerase chain reaction (RT-PCR) was inserted into the eukaryotic expression vector pEGFP-C_2. The recombinant plasmid was transfected into 7721 cells with Lipofectamine2000 and Gelatin-Zymography were adopted to detect the production of MMPs in the transfected cells. Results showed that ?ig-h_3/pEGFP-C_2 recombinant expression plasmid was successfully constructed and achieved high transfection efficiency. MMPs expression of the transfected cells was promoted significantly. These results suggest that overexpression of ?ig-h_3 promoted the production of MMPs, indicating that ?ig-h_3 may play roles in the invasive and metastatic processes of hepatoma.

Objective To investigate the correlation between obstructive sleep apnea syndrome(OSAS)with myocardial ischemia and arrhythmia.Methods To observe the occuring rate of premature beats and change of ST- segment,90 eases of OSAS patients were detected by the polysomnogram(PSG)and dynamic electrocardiogram at the same time.Results Total morbidity of myocardial ischemia was 32.2 % in OSAS patients,and it was 59.4 %, 15.8 %,20 % in serious,moderate and mild groups respectively.There was a statistically significant difference be- tween the three groups and the control group(P0.05).Conclusion As one of the risky factors of cardiovascular diseases,OSAS can induce myocardial ischemia and arrhythmia.
