With inlet temperature, specific gravity, feeding speed as independent variables, the comprehensive evaluating indexes of content of schisandrin and arctiin as dependent variable, the experimental data were fitted to a second order polynomial equation. Based on establishing the mathematical relationship between the comprehensive evaluating indexes and respective variables, Box-Benhnken central composite test and response surface analysis method was employed to optimize the spray drying technology of Biqiu granules ethanol extract. The optimal drying parameter was as follows: the inlet temperature was 175 degrees C, the specific gravity was 1.10, feeding speed was 32 r x min(-1). Under these conditions, the comprehensive evaluating indexes of spraying dry processes was 92.68, which was close to the model prediction. The spraying dry technology of Biqiu granules ethanol extract optimized by response surface methodology was accurate and feasible, which provided theoretical experiment basis for the industrialization production.

In the present study, terminal-restriction fragment length polymorphism (T-RFLP) technique was applied to assess the diversity and tissue distribution of the fungal endophyte communities of Alpinia officinarum collected from Longtang town in Xuwen county, Guangdong province, China, at which the pharmacological effect of the medicine plant is traditional considered to be the significantly higher than that in any other growth areas in China. A total of 28 distinct Terminal-Restriction Fragment (T-RFs) were detected with HhaI Mono-digestion targeted amplified fungal nuclear ribosomal internal transcribed spacer region sequences (rDNA ITS) from the root, rhizome, stem, and leaf internal tissues of A. officinarum plant, indicating that at least 28 distinct fungal species were able to colonize the internal tissue of the host plant. The rDNA ITS-T-RFLP profiles obtained from different tissues of the host plant were obvious distinct. And the numbers of total T-RFs, and the dominant T-RFs detected from various tissues were significantly different. Based on the obtained T-RFLP profiles, Shannon's diversity index and the Shannon's evenness index were calculated, which were significantly different among tissues (P < 0.05). Furthermore, two types of active chemicals, total volatile oils by water vapor distillation method and galangin by methanol extraction-HPLC method, were examined in the each tissue of the tested plant. Both of tested components were detected in all of the four tissues of the medicine plant with varying contents. And the highest was in rhizome tissue. Correlation analysis revealed there were significant negative correlations between both of the tested active components contents and calculated Shannon's diversity index, as well as the Shannon's evenness index of the fungal endophyte communities of the host plant (P = 0, Pearson correlation coefficient ≤ -0.962), and significant positive correlations between both of the tested active components contents and 325 bp dominant T-RF linkage to Pestalotiopsis (P = 0, Pearson correlation coefficient ≥ 0.975). In conclusion, A. officinarum is colonized by diverse fungal endophytes communities. The diversity of the fungal endophytes was found in the A. officinarum varied with differences of the tissue types of the host plants and was closely correlated with the accumulation of main active components, total volatile oils and galangin contents in the host plant tissue.

It is unanimously accepted that stroke is a highly heterogeneous disorder.Different subtypes of ischemic stroke may have different risk factors,clinical features,and prognoses.The aim of this study was to evaluate the risk factors,clinical characteristics,and prognoses of different subtypes of ischemic stroke defined by the Trial of ORG10172 in Acute Stroke Treatment (TOAST) criteria.We prospectively analyzed the data from 530 consecutive patients who were admitted to our hospital with acute ischemic stroke within 7 days of stroke onset during the study period.Standardized data assessment was used and the cause of ischemic stroke was classified according to the TOAST criteria.Patients were followed up till 30 and 90 days after stroke onset.It was found that large-artery atherosclerosis was the most frequent etiology of stroke (37.4％),and showed the highest male preponderance,the highest prevalence of previous transient ischemic attack,and the longest hospital stay among all subtypes.Small artery disease (36.4％) was associated with higher body mass index,higher plasma triglycerides,and lower plasma high-density lipoprotein cholesterol than cardioembolism.Cardioembolism (7.7％),which was particularly common in the elderly (i.e.,individuals aged 65 years and older),showed the highest female preponderance,the highest prevalence of atrial fibrillation,the earliest presentation to hospital after stroke onset,the most severe symptoms on admission,the maximum complications associated with an adverse outcome,and the highest rate of stroke recurrence and mortality.Our results suggest that ischemic stroke should be regarded as a highly heterogeneous disorder.Studies involving risk factors,clinical features,and prognoses of ischemic stroke should differentiate between etiologic stroke subtypes.

Objective To investigate the present status of Kaschin-Beck disease(KBD) in Qingzhou at present, and provide a scientific basis for decision-making in controlling the disease. Methods According to The National Technical Scheme for Endemic Disease Control in 2007, children aged 7 to 12 were chosen to receive clinical and X-ray examination in 3 villages of 2 towns in Qingzhou. Local adults aged 16 years and older were clinically diagnosed in 10 villages of 4 towns and divided into different groups according to the clinical degrees and their ages. The Diagnostic Criteria of Kashin Beck Disease(GB 16003-1995) was carded out by clinical and X-ray diagnosis. Results Two hundred and sixty school children aged 7 to 12 were clinically diagnosed, and the patients of I degree upwards of KBD were not detected. One hundred and ninety-eight school children aged 7 to 12 were examined by X-ray, and the detectable rate was 0(0/198). In 7099 adults aged 16 years old upwards clinically tested, 502 patients of degree I and higher of KBD were detected and the detectable rate was 7.07%(502/7099). The patients distributed mainly in the population aged 36 years old and older, accounting for 99.00% (497/502). Conclusions Although KBD in children have been controlled in Qingzhou, it is still serious in adults. So the monitoring of KBD should be carried on and prevention and control for KBD in adults should be strengthened.

This study was aimed to investigate the expressions of tumor necrosis factor-alpha (TNF-alpha), Interleukin-6 (IL-6) in serum and the incidence of multiple organ dysfunction syndrome (MODS) in pigs with hemorrhagic shock after the blood transfusion simultaneously combined with different doses of free hemoglobin (FHb) so as to provide guidance of banked blood with high concentration of FHb during war injury through understanding effect of FHb on the animals. The different doses of FHb were given intravenously during the recovery of pig from shock, the vital signs and functional changes of vital organs were monitored and the incidence of MODS was determined, as well as the serum specimens were collected and the TNF-alpha, IL-6 levels in serum were detected by ELISA. The results showed that there were statistical differences of serum levels of TNF-alpha and IL-6 in pigs after FHb 10 mg/kg infusion, as compared to shock control group. There was significantly difference of the serum levels of TNF-alpha, IL-6 after FHb 15 mg/kg infusion, compared to the control group. The incidence of MODS increased significantly. It is concluded that the blood infusion containing high dose (more than 10 mg/kg) of FHb influences significantly on the cytokines in pigs with hemorrhagic shock, and increases damage of cytokines to vital organs and the incidence of MODS. The tolerance dose of the pigs to free hemoglobin is about 10 mg/kg or so. The infusion of blood with less than 10 mg/kg is relatively safe for pig in hemorrhagic shock.

OBJECTIVETo develop diagnostic criteria of multiple organ dysfunction syndrome (MODS) by a prospective and multi-center clinical investigation.

METHODSThe data of 1087 MODS cases obtained from ICU of 37 hospitals from March 2002 to January 2005 in 11 provinces in China were analyzed in order to derive the diagnostic criteria of MODS.

RESULTSThis MODS diagnostic criteria involved 7 organs. To diagnose MODS, the original cause of MODS should be identified, then there should be two or more organs showing signs of dysfunction. The criteria for organ dysfunction were as follows. (1) Cardiovascular system: SBP < 90 mm Hg (1 mm Hg = 0.133 kPa), MAP < 70 mm Hg, signs of shock, ventricular tachycardia, ventricular fibrillation, or myocardial infarction; (2) Respiratory system: oxygenation index < 300 mm Hg; (3) Nervous system: indifference, restlessness, lethargy, light coma, or deep coma, Glasgow score < or = 14; (4) Blood system: PLT < 100 x 10(9)/L; CT, APTT, and PT prolonged or shortened; positive plasma protamine paracoagulation; (5) Liver: TBIL > 20. 5 micromol/L, ALB < 28 g/L; (6) Kidney: Cr > 123.8 micromol/L, urinary volume < 500 ml/24 h; (7) Gastro-intestine: bowel sounds decreased or disappeared; retention in the stomach, or positive occult blood feces with dark stools or haematemesis; intraabdominal pressure (intravesical pressure) > or = 11 cm H2O (1 cm H2O = 0.098 kPa). Any organ function met with one of the above conditions was considered to have dysfunction.

CONCLUSIONSThis diagnostic criterion of multiple organ dysfunction syndrome has been developed by this research, but it needs to accumulate experience by clinical practice and to revise the diagnosis criteria.

OBJECTIVETo evaluate the biomechanical performance of the spinal universal fixation system(GSPS) in treating the diseases related to spinal instability.

METHODSFour instable models and 4 fracture models were made of fresh pig's thoracolumbar specimens (T10-L3). Self-designed GSPS were used in the simulated operation. Axial loading test and torsion test were made. The stress-strain relation of the GSPS was observed. The extracting force of link bar from elastic jig was tested.

RESULTSThe strain value of each tested point changed linearly when the axial load changed from 0 to 600 N. There was linear relation between the torsion and the torsion angle. The latter was less than 6 degrees when the former reached 300 N x cm. The minimum extracting force of the link bar from the elastic jig was more than 3 300 N.

CONCLUSIONThe GSPS has high energy and high elasticity on anti-axial and anti-torsion load. It is stable to use elastic link bar.
