Objective The management of fluid infusion is crucial in severe sepsis/septic shock patients.The correlation of extravascular lung water index(EVLWI) versus oxygenation index ( PaO2/FiO2 ) and EVLWI versus intrathoracic blood volume index(ITBVI) were analysed in this present study. Method Totally 24 patients,admitted to the Intensive Care Unit of Second Affiliated Hospital of Zhejiang University, College of Medicine and diagnosed as severe sepsis/septic shock with acute lung injury and/or acute respiratory distress syndrome,were enrolled. ITBVI and EVLWI were detected with PiCCO technique. Correlation of EVLWI and PaO2/FiO2, ITBVI and EVLWI were analysed,respectively. Simple correlation and simple linear regression were used for statistical analysis. Results Significant negative correlation was found of EVLWI and PaO2/FiO2 ( r = - 0. 45, P ＜ 0.01).EVLWT = 14 mL/kg was defined as the cutoff value for the subgroup analysis. No correlation was found between EVLWI and PaO2/FiO2 in the subgroup with EVLWI≤ 14 mL/kg ( r = 0. 12, P = 0.243), but in the subgroup with EVLWI ＞ 14 mL/kg, significant negative correlation was found ( r = - 0. 47, P ＜ 0. 01 ). When EVLWI was higher than 14 mL/kg,EVLW should be decreased to improve oxygenation and other aspects should be taken into account. No significant correlation was found between ITBVI and EVLWI. A ITBVI value 1000 mL/m2 was also defined as the cutoff value for the subgroup analysis. No significant correlation was found in the subgroup with ITBVI≤ 1000 mL/m2( r = 0.13, P = 0.17), while significant positive correlation was found in the subgroup with ITBVI ＞ 1000 mL/m2. This result suggested that in patients of severe sepsis/septic shock with ALI/ARDS, when the blood volume is high, ITBV should be decreased to improve the oxygenation,however,it is not useful in the situation of high pulmonary vascular permeability. Conclusions Extravascular lung water has a important role in the fluid management in patients of severe sepsis/septic shock with ALI/ARDS.

BACKGROUND:Previous studies designed and made titanium metal rubber cervical disc prosthesis, and performed feasible studies on its effect on movement and stress distribution by replicating intervertebral discs. OBJECTIVE:To further observe the changes in the stability of goat cervical vertebra after metal rubber cervical disc replacement. METHODS:Nine goats were randomly divided into experimental group (n=6) and normal control group (n=3). Goats in the experimental group received metal rubber cervical disc replacement at C4/5segment. Goats in the normal control group did not receive any treatment. Radiographic data at anteroposterior and lateral position, hyperextension and excessive flexion were taken to measure intervertebral height, range of motion and intervertebral angle at C4/5 segment before operation, immediately, 4, 8, 12 weeks after operation. Subsequently, slicing and embedding of hard tissue at surgical segment, picric acid-acid fuchsin staining and scanning electron microscopy were conducted.RESULTS AND CONCLUSION:No significant difference in the intervertebral height and spinal range of motion at C4/5 segment at different time points was detected between postoperative results in the experimental group and preoperative results in the experimental group, normal control group. The intervertebral height at C4/5 segment was higher immediately, 4 and 8 weeks after surgery than preoperative result in the experimental group (P < 0.05). No significant difference in intervertebral angle at C4/5 segment was detectable between 4, 8 and 12 weeks postoperatively in the experimental group and normal control group (P < 0.05). At 4 weeks after surgery, bone did not contact with the edge of the prosthesis in the experimental group. At 8 weeks, the gap between bone and the prosthesis became smal, and some new bone attached to the edge of the prosthesis. At 12 weeks, a few osteoblasts were observed on the surface of the prosthesis. New osteogenic tissue grew into the prosthesis. Results suggested that metal rubber cervical disc replacement in the intervertebral space could maintain intervertebral height and range of motion in a short period, and tightly bind to the vertebral body.

This study was aimed to establish an HPLC method for the content determination ofepimedin A, epimedinB,epimedinC,epimedium glycoside,baohuosideI in epimedium flavonoids capsule. The elusion was performed on an Eclipse Plus C18column (250 mm× 4.6 mm, 5μm). The mobile phase was composed of acetonitrile and water with a gradient elution. The flow rate was set at 1 mL·min-1. The detection wave length was set at 270 nm. The column temperature was 25℃. The results showed that the linear ranges of epimedin A,epimedinB,epimedinC,epimedium glycoside,baohuosideI were 3.10-62.00μg·mL-1, 5.70-114.00μg·mL-1, 9.14-182.80μg·mL-1, 15.20-304.00μg·mL-1, and 1.56-31.20μg·mL-1, respectively. The correlation coefficientr was more than 0.999 3. The average recoveries were 101.06% (RSD = 1.05%,n = 6), 100.78% (RSD = 1.08%,n = 6), 99.17% (RSD = 1.14%,n = 6), 100.23% (RSD = 0.68%,n = 6), and 99.09% (RSD = 1.30%,n = 6), respectively. This experiment was precise, reproducible and stable. It was concluded that the method was simple and accurate, which provided a certain reference value for the multi-component assaying of epimedium flavonoids capsule.

This article was aimed to study the therapeutic effects and anti-inflammatory effects of Chinese and west-ern medicine ointment on fungal infection animals. Guinea pig models which were infected with Trichophyton rubrum or Microsporum lanosum were applied to observe the effects of antifungal infections on She-Zhi Qin-Xian (SZQX) ointment by transdermal administration. The ointment is the combination of miconazole nitrate, snake oil and Sophora flavescens which is traditional Chinese medicine (TCM). Simultaneously, the models of croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling were established to observe the curative effect of SZQX ointment. The results showed that the SZQX ointment had a protective role on both guinea pig models. The microscopic scale of localized lesions in infected guinea pigs was significantly decreased (P< 0.01). The effect of SZQX ointment was better than the single using of Chinese or western medicine. The SZQX ointment was also able to significantly reduce the croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling (P< 0.05, or P< 0.01) with distinct anti-inflammatory effect. And the effect of SZQX ointment was superior to the single using of either Chinese or western medicine. It was concluded that the SZQX ointment had significant antifungal infection and anti-inflam-matory effect.

Objective To explore the effects of self-differentiation,social support,social adaptation on suicidal ideation.Methods A simplified cluster sampling method,involving the random selection of 3097 college students in 23 departments,was used to estimate the scores of Chinese version of Self Differentiation Inventory for university student(SDI),Social Support Rating Scale(SSRC),College Student Adaptability Scale (CSAS) and Adult Suicidal Ideation Questionnaire(ASIQ).The independent-samples t-test,Pearson correlation coefficients and stepwise regression analyses were used as statistical analysis techniques.Results The correlation coefficients were negatively significant between suicidal ideation and self-differentiation,social support and social adaptation (r=-0.24,-0.17,-0.29,P＜0.001).Social adaptation showed the strongest predictability for suicidal ideation (β=-0.19,P＜0.001),followed by self-differentiation (β3=-0.13,P＜0.001),social support (β3=-0.08,P＜0.001).Independent samples t-test showed that college students with suicidal ideation showed a significant reduction in interpersonal adaptation,social support,self-differentiation compared to those without suicidal ideation.Conclusion Self-differentiation level,social support and social adaptability may be effective predictors for suicidal ideation among college students.Future intervention programs may focus on enhancing the interpersonal skills of college students to reduce prevalence of suicidal behavior.

Objective:To evaluate the relationship between the mechanism of promoting wound healing by modified autologous blood transfusion and metastasis-associated lung adenocarcinoma transcript 1 ( MALAT1) in diabetic mice. Methods:Twenty SPF ICR mice, weighing 21-25 g, in which the diabetic model was successfully established, were divided into 2 groups ( n=10 each) using a random number table method: modified preservation group (group I) and ordinary preservation group (group O). Peripheral venous blood samples were collected and stored in the corresponding preservation solution for 7 days.The platelet aggregation rate, blood glucose, serum glycosylated hemoglobin (GHB) and phosphodiesterase (DPG) concentrations and WBC were measured.Autologous blood was transfused back immediately after the wound model was established.The percentage of wound healing area was calculated at 7, 10 and 14 days after autologous blood transfusion.The expression of hypoxia-inducible factor-1α, vascular endothelial growth factor, matrix metalloproteinase-9, β-actin, type Ⅰ collagen (Col Ⅰ), Col Ⅲ protein and mRNA and MALAT1 was determined by Western blot, immunohistochemistry and quantitative real-time polymerase chain reaction respectively, at 14 days after transfusion. Results:Compared with group O, the blood glucose, serum concentrations of GHB and DPG, and WBC were significantly decreased, platelet aggregation rate was increased, the percentage of wound healing area was increased, the positive staining rate of Col Ⅰ and Col Ⅲ was increased, and the expression of hypoxia-inducible factor-1α, vascular endothelial growth factor, matrix metalloproteinase-9, ColⅠ, Col Ⅲ and β-actin protein and mRNA and MALAT1 was up-regulated in group I ( P<0.05). Conclusion:The mechanism by which modified autologous blood transfusion promotes wound healing may be related to up-regulating MALAT1 expression in diabetic mice.
