Objective To evaluate the anti-tumor effects of chemotherapeutic drugs on human gastric cancer cells. Methods From April 2006 to February 2007, 84 patients with gastric cancer underwent surgical resection at General Hospital of Jinan Military Command. The single-cell suspension of these gastric tumors was prepared. The gastric cancer cells were cultured with hydroxycamptothecin, cisplatin, adriamycin, 5-fluorouracil and mitomycin for 48 hours, and changes in activity of the gastric cancer cells were studied via MTT assay. The expression of survivin and PTEN was detected by immunohistochemistry. Data were analyzed by chi-square test, rank sum test and Fisher exact test. Results The anti-tumor effects of different chemotherapeutic drugs were different, and the poorly-differentiated gastric cancer cells were more sensitive to the cytotoxic effects of chemotherapeutic drugs than the well-differentiated gastric cancer cells. The expression levels of survivin in the signet ring cell carcinoma, mucinous adenocarcinoma and other poorly-differentiated adenocarcinoma were significantly higher than those in papillary carcinoma and tubular carcinoma (χ~2 = 10.625, P <0.05), while the expression of PTEN was inverse to that of survivin (χ~2 = 6.060, P < 0.05). The expression of survivin was related to the resistance of the gastric cancer cells to 5-fluorouracil and adriamycin (χ~2 = 6.609, 6.350, P < 0.05). Conclusions In vitro chemosensitivity assay is helpful in selecting the chemotherapeutic regimen for specific types of gastric cancer. Survivin may contribute to the chemotherapy-resistance of certain types of gastric cancer cells, and its expression is related to that of PTEN.

To explore the mechanism of the absorption enhancement of Angelica dahurica extract (Ade), the absorption mechanism of baicalin in the Scutcllaria water extraction as well as the effect of Angelica dahurica extract on absorption of baicalin were investigated. In order to determine the main absorption site, everted intestinal sac model was used to study the effect of Angelica dahurica extract on the absorption of baicalin at duodenum, jejunum, ileum and colon. In situ single pass intestinal perfusion model was performed to study the absorption of various concentrations of baicalin and the effect of Angelica dahurica extract on the absorption of baicalin at the main absorption site. To authenticate the consequence of perfusion by getting the blood from the hepatic portal vein and determine the concentration of the baicalin in the blood. The result showed that baicalin could be absorbed at all of the four intestinal segments with increasing absorption amount per unit as follows: ileum > colon > jejunum > duodenum. The absorption ofbaicalin in the duodenum significantly increased with Angelica dahurica extract, thus, duodenum was chosen to be the studying site. Apparent permeability values (Papp) and absorption rate constant (Ka) of baicalin in the duodenum increased gradually with higher concentrations. When the concentration of baicalin rises to a certain degree, the absorption increase had a saturable process, the absorption of baicalin may be an active transportation. Baicalin may be not a substrate of P-gp as verapamil which had not significantly affected the Papp and Ka of baicalin. The absorption of baicalin in the duodenum significantly increased (P < 0.01) in the two models with Angelica dahurica extract and the concentration of baicalin in the blood from the hepatic portal vein showed that the Angelica dahurica extract can increase the absorption of baicalin.

Objective To evaluate the accuracy and value of measurement of left ventricular systolic function in dilated cardiomyopathy (DCM) and hypertrophic cardiomyopathy (HCM) patients with stereo three-dimensional echocardiography (S3 DE). Methods End-diastolic volume (EDV), end-systolic volume (ESV),stroke volume(SV) and ejection fraction(EF) of the left ventricle were measured with M-mode echocardiography(ME),two-dimensional echocardiography(2DE) and S3DE in DCM patientsC20 cases). HCM patients(20 cases),and normal controls(20 cases). The different results among the three groups or three methods were analyzed. Results (①In all the three groups,the results of EDV,ESV,and SV obtained with ME were significantly higher than those obtained with S3DE( P <0. 01). Only in normal group( P <0. 01) and HCM group ( P <0. 05) ,the results of EF obtained with ME and 2DE were significantly higher than that obtained with S3DE. ②By S3DE,compared with normal group,EDV,ESV were increased and EF was decreased obviously in DCM group (all P <0. 01); while in HCM group, only SV was significantly higher( P < 0. 01). ③EDV, ESV, and EF measured by S3DE were correlated and fit well with those measured by 2DE(r = 0.778,0.876, 0.932;R2 =0.605,0.767,0.869;all P <0.01). ④Within HCM group,excluding the impact of heart rate,cardiac output (CO) was highly correlated with SV( r = 0. 987,P < 0. 01). Conclusions S3DE can real-time display the stereo structure of the heart, and accurately and reliably assess the left ventricular systolic function, with a priority over traditional ME and 2DE methods. EDV,ESV, and EF are still effective indicators for the clinical assessment of left ventricular systolic function. SV obtained with S3DE will be expected to be the more sensitive and accurate value in assessing left ventricular systolic function in patients with early-stage cardiomyopathy.

OBJECTIVETo identify the risk factors for low birth weight (LBW) in Chinese newborns with varied characteristics.
METHODSA 1:1 matched case-control study, with 999 babies of LBW was performed in 44 counties of 11 provinces in China during July to October, 1998 for identifying their risk factors using simple and multivariate logistic regression models.
RESULTSThe determinants of LBW in China included factors, such as multiparity (OR = 106.9), preterm birth (OR = 18.7), abnormal maternal health status (OR = 2.61) and maternal malnutrition (OR = 3.42), maternal medical conditions during pregnancy (OR = 1.93), maternal schooling (OR = 1.43), et al. Distribution of the risk factors for LBW was significantly different between coastal, inland and remote areas. LBW was mainly attributed to intrauterine growth retardation (IUGR) (71.6%) in the rural areas, and to multiparity and preterm birth, in addition to IUGR, in the urban areas. There was different in the risk factors for LBW with preterm births and IUGR.
CONCLUSIONSIt is an effective way to reduce incidence of low birth weight in China that all measures for prevention and control should be relevant to its risk factors.
