OBJECTIVETo evaluate the effects of Ginaton (Ginkgo biloba leaf extract) on the myocardial injury markers (MIMs) during cardiopulmonary bypass (CPB).

METHODSForty patients with congenital heart diseases, scheduled to take atrial septum or ventricular septum repairing operation, were randomly divided into the Ginaton group and the control group, 20 cases in each group. Patients in both groups received St. Thomas' cardioplegic perfusion via radix aortae, while Ginaton (0.5 mg/kg) was added into the perfusion for the Ginton group. Cardiac surgery were started after complete heart arrest. Central venous blood was obtained before and at 0, 6th, 12th, 24th and 48th hour after operation for detection of serum C reaction protein (CRP) by immunoturbidimetry, as well as creation kinase-MB isoenzyme (CK-MB), cardiac troponin T (cTnT) and cardiac troponin I (cTnI) with enzyme-linked immunosorbent assay (ELISA).

RESULTSThere was no difference in serum concentration of CRP, CK-MB, cTnT and cTnI between the two groups before operation (P > 0.05). These indexes increased immediately after operation in both groups ( P < 0.05). They reached the peak value 12 hrs after CPB and reduced to normal level 48 hrs post-operation in the control group, with the value significantly higher than that in the Ginaton group at all the corresponding time points (P < 0.05, or P < 0.01).

CONCLUSIONPerfusion with Ginaton during CPB could significantly decrease the release of MIMs and improve post-CPB cardiac function recovery, exerting favorable myocardium-protective effects.

OBJECTIVETo investigate the effect and clinical value of ginkgo biloba extract (Ginaton) on the plasma vascular endothelial growth factor (VEGF) in patients during peri-operative period of cardiac surgery.

METHODSTwenty patients scheduled to receive cardiac operation were randomly assigned to 2 groups by a digital table. For the 10 patients in the control group, the cardiopulmonary bypass (CPB) was established in routine and received cold (4 degrees C) St. Thomas' cardioplegia perfusion (15 mL/kg) via aortic root after ascending aorta blocking, as for the 10 patients in the Ginaton group, the same was done but with 0.5 mg/kg of Ginaton added to the cardioplegia perfusion. Plasma VEGF contents were detected by ELISA at different time points, i.e., before and after anesthesia induction (T1, T2), after aorta intubation (T3), 0.5 h after aorta clamping (T4), 0.5 h after aorta declamping (T5), immediate after terminating the operation (T6), 6 h after operation (T7), and 24 h after operation (T8).

RESULTSIn the control group, VEGF level began to rise at T, and reached the peak at T7(P < 0.01), while in the Ginaton group, it reached the peak early at T, (P < 0.01), and began to drop at T (P < 0.01).

CONCLUSIONGinaton could induce the production of VEGF, which may be one of the mechanisms for its myocardial protection.

OBJECTIVETo describe the temporal trends in the mortality rate of gastric cancer during the period of 1988 and 2010, and to predict the gastric cancer mortality between 2016 - 2020.

METHODSThe data of gastric cancer mortality in Linzhou city between 1988 and 2010 was extracted from the cancer registry, including a total of 11 714 cases, covering 22 447 073 person-years. The mortality rate of gastric cancer of each 5-year period was calculated by sub-site and gender. Age-standardized rate (ASR) was calculated using the Chinese standard population in 1982. Intrinsic estimator (IE) model was used to fit the mortality trend by sub-site and gender, and to predict the mortality of gastric cancer in Linzhou city between 2016 and 2020.

RESULTSFrom 1988 to 2010, the gastric cancer mortality in Linzhou city was 52.18/100 000 (11 714/22 447 073) with the ASR at 49.23/100 000; the mortality in male was 67.02/100 000 (7678/11 455 512) with ASR at 68.68/100 000 while the mortality in female was 36.72/100 000 (4036/10 991 561) with ASR at 32.12/100 000. The mortality of cardia carcinoma was 27.87/100 000 (6257/22 447 073) with the ASR at 26.37/100 000; while the mortality of non-cardia carcinoma was 24.31/100 000 (5457/22 447 073) with the ASR at 22.86/100 000. The ASR of gastric cancer during 1988 - 1990 was 63.37/100 000 (1653 cases) and decreased by 28.34%, to 45.41/100 000 (2622 cases) during 2006 - 2010. The IE model showed that the birth cohort effect decreased greatly. The mortality risk of cardia carcinoma in population born after 1950s, decreased significantly; and the mortality risk of non-cardia carcinoma in population born in 20 century continually decreased. The death of gastric cancer among the population over 30 years old was predicted to be 3626 cases, increasing by 40.60% compared with the number between 2006 and 2010 (2579 cases). Among them, the mortality of cardia carcinoma increased by 51.89% (predicted number between 2016 and 2020 was 2456 cases, and 1617 cases between 2006 and 2010), and the mortality of non-cardia carcinoma increased by 21.62% (predicted number between 2016 and 2020 was 1170 cases, and 962 cases between 2006 and 2010).

CONCLUSIONThe mortality rate of gastric cancer in Linzhou city showed a decreasing trend during the period of 1988-2010, being mainly attributed to the cohort effect. However, the mortality will still increase in the future, between 2016 and 2020.

OBJECTIVETo estimate the number of death from malignant tumor and to assess the completeness of cancer registry data using the capture-recapture method.

METHODSData about death form malignant tumor were collected during the period of 2004 and 2005 from cancer registry, civil administration and police registries in Linzhou. Cases in every source were matched on the address, name, sex, ID card, date of death, cause of death. A 3-source log-liner poisson model was used to estimate the real number of death from malignant tumor during the period of 2004 and 2005 in Linzhou.

RESULTSThe real number of death from malignant tumor that estimated by capture-recapture method was 3140 (95% CI: 3124 - 3161) during 2004-2005 year in Linzhou. Underreported number by source linkage was 71. Log-liner model demonstrated positive dependence between the 3 sources, implying that 2-source model would underestimate missing cases. Using the mortality number estimated by the capture-recapture as the denominator, under-reporting rate of cancer registry was 6.6%.

CONCLUSIONIt is feasible to estimate the real number of death from malignant tumor and to correct data bias by applying the capture-recapture method.

This study was aimed to observe and analyze the effectiveness of platelet transfusion. The platelet count of 1786 patients before transfusion and on 20-24 hours after transfusion was determined by using Auto-Hematology Analyzer, the percent platelet recovery (PPR) was calculated, the platelet transfusion efficiency (PTE) was evaluated by PPR and hemorrhage presentation after platelet transfusion, and the PTE was statistically analyzed according to disease cause, transfusion frequency, platelet type and once transfusion amount. The results showed that the total PTE of 1786 patients was 52.5%. The comparison of PTE among groups of disease cause showed that PTE in leukemia and aplastic anemia (AA) was lowest, as compared with that of other diseases (P < 0.05), while PTE in operation group was highest. The comparison of PTE among groups of transfusion frequency revealed also statistical difference (P < 0.01), meanwhile PTE decreased with increasing of transfusion frequency. The comparison of PTE among groups of platelet type (platelet phoresis or platelet concentrate) showed statistical difference (P < 0.01). The comparison of PTE among groups of platelet concentrate of once transfusion amount showed no statistical difference (P > 0.05). It is concluded that the PTE closely relates with disease cause of patients, moreover transfusion frequency also associates with PTE, the more frequency of transfusion, the higher possibility of transfusion refractoriness. The PTE of platelet pheresis is obviously superior to that of platelet concentrate, while PTE of platelet concentrate not significantly relates with once adequate or not.

OBJECTIVETo analyze the level of mortality of brain tumor and its changes at different periods in China.

METHODSDeath records for tumor of brain and central nervous system, which the code of international classification of diseases-10 (ICD-10) were C70-C72, were extracted from the database of the Third National Retrospective Sampling Survey of Death Causes in China during 2004 to 2005. The corresponding population data was linked to the data of death records, that the total population was 142 660 482 person years (72 970 241 person years in male, 69 690 241 person years in female). Then crude death rate, age-specific death rate, the constitute proportion to all death caused by tumor and the age-standardized death rate were calculated by taking reference of Chinese standard population or the world standard population. The indexes of mortality were compared with that of previous retrospective surveys of death causes at 1973 - 1975 and 1990 - 1992.

RESULTSThe result showed that during 2004 to 2005, the number died from brain tumor was 4463 and the crude death rate in China was 3.13/100 000, which accounted for 2.30% of the all number died from tumor (193 841 cases). The age-standardized death rate by Chinese standard population was 2.37/100 000 and the age-standardized death rate by the world standard population was 2.90/100 000. Of which, there were 2556 death cases for males with crude death rate of 3.50/100 000. While for females, the crude death rate was 2.74/100 000 (1907 death cases). Age-standardized death rates by Chinese standard population in male and female were 2.71/100 000 and 2.03/100 000 respectively. The age-standardized death rate by world standard population was 3.31/100 000 for male and for female that was 2.48/100 000. The age-specific death rate of brain tumor in China was increasing as age growing. The crude death rates were 3.78/100 000 (1809/47 899 806), 2.80/100 000 (2654/94 760 676), and the age-standardized death rates by Chinese standard population were 2.71/100 000 and 2.20/100 000 for urban and rural area respectively, and the crude death rates of brain tumor in east, middle and west region were 3.60/100 000 (1894/52 556 694), 3.14/100 000 (1565/49 781 225), 2.49/100 000 (1004/40 322 563). The age-standardized death rates by Chinese population were 2.57/100 000, 2.43/100 000 and 2.02/100 000. Compared to the data in the first survey during 1973 to 1975, in which the crude death rate was 1.13/100 000 and age-standardized death rate by Chinese standard population was 1.10/100 000, the crude death rate and age-standardized death rate by Chinese standard population were increased by 176.99% and 115.45% respectively. While compared with the second survey during 1990 to 1992, that crude death rate was 1.89/100 000 and age-standardized death rate by Chinese standard population was 1.74/100 000, the rising percent of the rates were 65.61% and 36.21% respectively.

CONCLUSIONThe level of mortality of brain tumor has been changing with an increasing trend from the period of 1973 - 1975 to the period of 2004 - 2005. The rate in male was higher than that of female with great diversity in different areas in China.

Objective To analyze the molecular characteristics of the newly isolated two Japanese encephalitis virus strains(JEV) in Wuhan. Methods The mosquitoes were collected in Wuhan from April to October in 2009. The envelope (E) protein gene of JEV was detected using RT-PCR and sequenced.Sequence comparisons and phylogenetic analysis were conducted using DNAstar and MegAlign. Results Two Japanese encephalitis virus (JEV) strains (WHJX09-9, WHJX09-10 ) were isolated from Culex tritaeniorhynchus among 16 mosquito pools and identified as genotype I. The result showed that the homology of the two strains was 98. 9％ in nucleotides and 100％ in deduced amines. The comparison between the new genotype 1 JEV strains and live attenuated vaccine strain SA14-14-2 in E gene showed that the homology of nucleotide sequence was 87.4％ and 87.9％ ,the homology of amino acid was 96. 9％ (totol 15 amino acid were different) in E gene. The mutation sites of amino acid distributed among three different coding domain,but no antigen binding site and neurotoxin-involved site of amino acid were changed. Conclusion Wuhan had appeared a new genotype of JEV which was different from the former strain isolated in Wuhan,the new JEV strains still had neurotoxicity but had high homology with the vaccine strains adopted in Wuhan. The vaccine could still be adopted to prevent Japanese encephalitis if steps were take to eradicate mosquitos at the same time. laboratory surveillance were also an important task to build an early-warning mechanism against JEV.

OBJECTIVETo evaluate the effect of water pollution with dexamethasone on intestinal flora in mice.

METHODSTwenty Balb/c mice were randomly divided into control group and low-, moderate- and high-dose dexamethasone groups. The mice in dexamethasone groups were exposed to dexamethasone sodium phosphate in drinking water at doses of 0.035, 0.225, and 2.25 ng for 36 days. The changes in behaviors, fur condition, and feces of the mice were observed daily. All the mice were sacrificed at 36 days and the tissues in the ileocecal region was collected for denaturant gradient gel electrophoresis (DGGE) of 16S rDNA V6 variable regions of microbes and sequence analysis with BLAST.

RESULTSThe mice in the 3 dexamethasone groups all showed aggressive behaviors. Cluster analysis of DGGE graph showed relatively stable floras in the ileocecal region in all the mice, but principal component analysis identified differences in the dominating flora among the groups. Diversity analysis of the flora revealed significantly increased amount and types of bacteria in the intestinal flora in all the 3 dexamethasone groups (P<0.05 or 0.01) compared with the control group. Sequence analysis of 16S rDNA V6 regions showed 15 common bacterial species and 2 differential species between the dexamethasone groups and the control group with changes in the type and proportion of the dominating bacterium in the dexamethasone groups. Lactobacillus colonization was detected in the control group but not in moderate- and high-dose dexamethasone groups, and Shigella species were found in the latter two groups.

CONCLUSIONSWater contamination with dexamethasone can affect the nervous system of mice, cause changes in the types and amounts of intestinal bacteria and the dominating bacteria, and inhibit the colonization of probiotics in the intestinal floras to increase the risk of invasion by intestinal pathogenic bacteria.

OBJECTIVEUsing the data on death for esophagus and stomach cancers in Linzhou cancer registration system, the mortality was described as well as the changing trend was analyzed.

METHODS18 240 death recorders for the both cancers during 1988 to 2003 were drawn from Linzhou cancer registration system. Of which, 10138 cases were esophageal cancer and 8102 cases were gastric cancer. Then data were stratified by sex, age, year and then linked to demographic classifications. The mortalities of two topographic site cancers were calculated and the age-adjusted rates were calculated by direct standardization to the world population. The Joinpoint model was used to get the estimated annual percent change (EAPC) of the age-adjusted rates, so to estimate the death rate change trends of both cancers in population of Linzhou city.

RESULTSIn 2003, the age-adjusted mortalities of esophageal cancer and gastric cancer were 68.47 per 100,000 and 57.01 per 100,000 respectively of Linzhou city. From 1988 to 2003 the death rates for both of cancers had showed the decline trends. The EAPC of the mortality for esophageal cancer was -3.82 (-4.81 - -2.82, P < 0.001) and that for gastric cancer was -2.95 (-4.16 - -1.73, P < 0.001) respectively.

CONCLUSIONThe declining trend in was observed the mortality of esophageal and gastric cancer in Linzhou by this study.
