Objective To study the demographics and background of attempted suicide individuals,such as age,gender,mode of suicide,seasonality,etc.so as to improve prevention strategy.Methods By sequential sampling analysis,there were data of 895 survivors from committed suicide taken from 907 attempted suicide individuals recorded in an emergency room of a local hospital between 2002 and 2008 for retrospectively study.Results The sample was composed of 191 males and 704 females with a male to female ratio of 1∶3.69.The adolescents and young adults aged 15-34 years accounted for the vast majority of attempted suicide individuals with the peak at the age of 24 years.The number of committed suicide remarkably reduced after the age of 47 years.The major mode of committed suicide was ingestion of poisons.The incidence of committed suicide declined significantly from 2002 to 2005,and then increased between 2005 and 2008.It was more often occurred in the seasons of Spring and Summer. Conclusions Age,gender,and seasonality are associated with attempted suicide in china,and these risk faetors should be the focuses of suicide prevention in China.Additionally,control of pesticides and psychological intervention should be the parts of the work to prevent suicide in the this cohort of special individuals with propensity of committed suicide.

Objective: To explore the early diaghostic value of thyroid hormone level in patients with left ventricular diastolic dysfunction. Methods: Our work included 4 groups:①Normal control group, n=40,②Impaired left ventricular diastolic function
group, n=40,③Failure of left ventricular diastolic function group, n=41 and④Impaired left ventricular systolic function group, n=40. The cardiac function was assessed by color Doppler lfow imaging and tissue Doppler imaging for the early diastolic mitral lfow velocity (E), the peak early diastolic mitral annular velocity (Em) and the ratio of E/Em. The blood levels of NT-proBNP and FT3, FT4, TSH, rT3 were examined in clinical laboratory.
Results: Blood levels of FT3 and rT3 were different in pair wise comparison among 4 groups, P<0.05, and FT4 and NT-proBNP were different in pair wise comparison among 4 groups, except for Normal control group and Impaired left ventricular diastolic function group, P<0.05. The TSH level was similar among 4 groups, P>0.05. The ratio of E/Em was negatively related to FT3 (r=-0.724, P<0.05) and FT4 (r=-0.49, P<0.05), while positively related to rT3 (r=0.87, P<0.05) and NT-proBNP (r=0.83, P<0.05).
Conclusion: The changes of thyroid hormone level may exist in patients with impaired diastolic function and it may vary with the severity of the cardiac dysfunction. Blood levels of NT-proBNP with thyroid hormone might be used as a reference index for early diagnosis of diastolic dysfunction.

Objective To investigate the effects of parecoxib pretreatment on the intrapulmonary shunt during one-lung ventilation in patients undergoing esophageal cancer resection.Methods Forty ASA Ⅰ or Ⅱ patients of both sexes,aged 25-64 yr,weighing 45-70 kg,with body height 156-178 cm,undergoing elective esophageal surgery,were randomly divided into 2 groups (n =20 each):normal saline group (group NS) and parecoxib group (group P).Parecoxib 40 mg (in normal saline 10 ml) was injected intravenously 30 min before anesthesia in group P,while the equal volume of normal saline was given instead of parecoxib in group NS.Anesthesia was induced with iv injection of propofol,fentanyl and rocuronium.Bronchial blocker was inserted after tracheal intubation and the correct position was confirmed by bronchoscopy.Anesthesia was maintained with iv infusion of propofol and remifentanil and intermittent iv boluses of atracurium.HR,MAP,SpO2 and mean airway pressure (Pmean)were determined at 5 min of two-lung ventilation,at 40 min of one-lung ventilation,and at 30 min after re-expansion of the collapsed lung (T0-2).Blood samples were taken simultaneously from jugular vein and radial artery for blood gas analysis.Intrapulmonary shunt (Qs/Qt) was calculated.Results There were no significant differences in hemodynamic parameters and Pmean between the two groups (P ＞ 0.05).PaO2 was significantly lower,while Qs/Qt was significantly higher at T1,2 than at T0 in groups NS and P (P ＜ 0.05).PaO2 was significantly higher,while Qs/Qt was significantly lower at T2 than at T1 in groups NS and P (P ＜ 0.05).Qs/Qt was significantly lower at T1,2 and PaO2 was significantly higher at T2 in group P than in group NS (P ＜ 0.05).Conclusion Parecoxib 40 mg injected intravenously at 30 min before anesthesia can reduce the intrapulmonary shunt during one lung ventilation in patients undergoing esophageal cancer resection.

Objective: To inquire into the testis gene change of mouse model with kidney-yang deficiency induced by overfatigue and excessive sexual life, the modern science mechanism of syndrome of kidney-yang deficiency and kidney controlling reproduction can be revealed on the gene level. Methods: The model of kidney-yang deficiency was established by each male mouse with six female mice keeping in the same cage, and all the male mice were forced to swim for 30-40 minutes everyday lasting for four weeks. The testis genes of mice in control group and model group were detected with Mouse OneArrayTM Whole Genome DNA microarray. The differentially expressed genes were screened under the condition of the relative fluorescence intensity ratio of the two groups ≥2 and ≤0.5 and further classified according to gene function by using Molecule Annotation System (MAS) created by CapitalBio Corp. Beijing, China. Results: The mouse model with kidney-yang deficiency was established successfully by the method of overfatigue and excessive sexual life. The scatter plot of gene expression profiles of comparing control group with model group was drawn. Differentially expressed genes were screened, including 2425 up-regulated genes and 3080 down-regulated genes. Among the first one hundred up-regulated genes, 41 genes were known and among the first one hundred down-regulated genes, 62 genes were known. These genes were mainly related to the cellular structure/function, material/energy metabolism, signal transduction/transmission, inflammation/immunization, cell apoptosis, transcription/translation,proliferation/differentiation and cell cycle. Conclusion: The testis gene of kidney-yang deficiency mouse had a wide change. The essence of kidney-yang deficiency syndrome and the theory of the kidney originating and controlling life reproduction were explained on the gene level.

The inter-species differences of estradiol metabolism were investigated in human, Beagle dog and rat liver microsomes by comparing enzyme kinetics of parent drug and the formation of its major metabolites. The incubation systems of estradiol with liver microsomes of the three species were optimized in terms of estradiol concentration, microsomal protein content and incubation time. The concentrations of estradiol and its metabolites were measured by LC-MS/MS method. The t1/2, CLint, CLh, Km and Vmax of estradiol incubated with male human liver microsomes were 40.02 +/- 8.32 min, 41.39 +/- 6.57 mL x min(-1) x kg(-1), 13.81 +/- 12.36 mL x min(-1) x kg(-1), 26.8 +/- 6.99 micromol x L(-1) and 0.75 +/- 0.92 micromol x L(-1) x min(-1), respectively. The corresponding parameters of female human were 44.71 +/- 10.21 min, 29.85 +/- 8.97 mL x min(-1) x kg(-1), 0.01 +/- 0.68 mL x min(-1) x kg(-1), 44.2 +/- 7.73 micromol x L(-1) and 1.27 +/- 4.41 micromol x L(-1) x min(-1), that of male dog were 21 +/- 7.33 min, 165.53 +/- 29.33 mL x min(-1) xkg(-1), 26.01 +/- 8.39 mL x min(-1) x kg(-1), 19.5 +/- 7.34 micromol x L(-1) and 1.6 +/- 0.65 micromol x L(-1) x min(-1), that of female dog were 25.5 +/- 5.32 min, 135.11 +/- 42.34 mL x min(-1) x kg(-1), 0.24 +/- 3.18 mL x min(-1) x kg(-1), 8.33 +/- 6.32 micromol x L(-1) and 0.51 +/- 2.15 micromol x L(-1) x min(-1), that of male rat were 5.11 +/- 3.84 min, 485.63 +/- 36.52 mL x min(-1) x kg(-1), 49.57 +/- 15.29 mL x min(-1) x kg(-1), 62 +/- 13.74 micromol x L(-1) and 19.16 +/- 9.67 micromol x L(-1) x min(-1), and that of female rat were 7.0 +/- 3.69 min, 354.82 +/- 33.33 mL x min(-1) x kg(-1), 8.04 +/- 3.23 mL x min(-1) x kg(-1), 35.38 +/- 7.65 micromol x L(-1) and 8.39 +/- 4.91 micromol x L(-1) min(-1), respectively. There were nine metabolites detected from all the three species, but the relative amounts of the metabolites generated were different in three species. The results indicted that the major phase I metabolic pathway of estradiol was similar in the liver microsomes from all the three species. However, the inter-species differences were found in the view of relative amounts of the metabolites as well as the metabolic characteristics of estradiol in liver microsomal incubation.
