The paper was a study on the effect of UBIO on ischemic strokes. 80 Cases with acute ischemic strokes were randomly divided into two groups:UBIO group and control group. Clinic effectiveness,hemorheology and in vitro infarction were studied before and after 14 days treatment. Clinical results showed that the excellent,effetive rate of UBIO group was respectively better than that of control group (P<0.05). The results of hemorheology and in vitro infarction showed UBIO has a faster effectiveness than control group. The results indicate that UBIO therapy is a hopeful assistant method for the treatment of acute ischemic strokes.

Objective To compare the blood high mobility group box-1 (HMGB-l) versus N-terminal prohormone of brain natriuretic peptide (NT-proBNP) for assessment of cardiac dysfunction in the patients with severe sepsis.Methods Ninety-eight patients of both sexes,aged 18-75 yr,were divided into 3 groups according to left ventricular ejection fraction (LVEF):non-cardiac dysfunction group (LVEF ≥ 50 ％,n =43),mild cardiac dysfunction group (30％ ≤ LVEF ＜ 50％,n =41),and severe cardiac dysfunction group (LVEF ＜ 30％,n =14).Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was performed.Venous blood samples were obtained for determination of the concentrations of HMGB-1 and NT-proBNP.Days of hospitalization and the survival rates within 28 days after admission to hospital were recorded.Pearson correlation between blood HMGB-l,NT-proBNP concentrations and LVEF was analyzed.Results Compared with non-cardiac dysfunction group,LVEF was significantly decreased,APACHE Ⅱ score and blood HMGB-1 and NT-proBNP concentrations were increased,days of hospitalization were prolonged,and the survival rates were decreased in mild and severe cardiac dysfunction groups,and the changes in the parameters mentioned above were more obvious in severe cardiac dysfunction group.The correlation coefficient between blood HMGB-1 concentration and LVEF was -0.639 and between blood NT-proBNP concentration and LVEF was-0.521,showing significant difference.Conclusion Blood HMGB-1 concentration provides higher reliability than blood NT-proBNP concentration in assessing the degree of cardiac dysfunction in the patients with severe sepsis.

Objective To observe the levels of serum VEGF in different molecular subtypes of breast cancer and explore its relationship with response to neoadjuvant chemotherapy. Methods Levels of serum VEGF in 110 cases with breast cancer underwent neoadjuvant chemotherapy were detected by ELISA prior to and after 3 cycles of neoadjuvant chemotherapy. Clinical response to neoadjuvant chemotherapy was evaluated by physical examination and ultrasonography. Results Levels of serum VEGF were significantly increased in breast cancer patients with≥4 lymph node metastasis than those with < 4 lymph node[(307.31 ± 101.42) pg/mL vs. (170.16 ± 73.07) pg/mL,P = 0.017]. Patients with positive HER-2 status had significantly higher levels of serum VEGF than those with HER-2 negative status [(235.15 ± 88.42 ) pg/mL vs. (179.82 ± 69.90) pg/mL, P = 0.024]. No significant difference was observed among age , menopausal status and hormone status. In patients with neoadjuvant chemotherapy of cCR and Cpr,the mean levels of serum VEGF were (205.75 ± 78.12) pg/mL and (226.04 ± 89.04) pg/mL, respectively. After 3 cycles of chemotherapy, levels of serum VEGF decreased to (145.15 ± 67.08) pg/mL and (161.27 ± 93.57) pg/mL. There was significant difference between two groups (P=0.009,0.014). In patients with SD or PD response, no significant difference was observed between levels of serum VEGF before and after chemotherapy (P = 0.577). Conclusions Levels of serum VEGF in breast cancer correlate with lymph nodes metastasis and HER-2 status and may decrease after neoadjuvant chemotherapy. However,whether or not the levels of serum VEGF can be used as a biomarker for response to neoadjuvant chemotherapy needs more further studies.

Objective To explore related factors of amputation in patients with diabetes foot ulcer(DFU) and provide the evidence of reducing amputation rate.Methods A total of 307 inpatients with DFU in this hospital from October 2013 to December 2015 were collected and divided into amputation group(n=28) and non-amputation group(n=279).The clinical data and laboratory data were treated with single variable analysis and multivariate Logistic regression analysis.Results Single variable analysis showed that hospitalization time,hyper-sensitive C-reactive(hs-CRP) and fibrinogen(FIB) level were significantly increased in amputation group(P＜0.05) when compared with non-amputation group,and the hemoglobin (Hb) level,high-density lipoprotein cholesterol(HDL) and serum albumin (ALB) level in amputation group were markedly lower than in non-amputation group(P＜0.05).Amputation rate was significantly different among different Wagner grades (P=0.000).Multivariate Logistic regression analysis showed that hospitalization time,Wagner grade were independent risk factors of amputation in patients with DFU,OR values were 1.024(95％CI:1.009-1.039) and 2.779 (95％CI:1.753-4.404),respectively.While HDL was a protective factor of amputation in patient with DFU (OR=0.161;95％CI:0.036-0.729).Conclusion The higher the rank of Wanger in DFU patients are,the longer hospital stay and the higher amputation risk become.HDL is the protective factor of DFU amputation.

Objective To evaluate the occupational health literacy (OHL) level and its influencing factors among individuals of six key industries from Jiulongpo District, Chongqing City. Methods A total of 2 022 frontline workers from six key industries in the Jiulongpo District of Chongqing City were selected as the research subjects using a cluster sampling method. The OHL level of the workers were assessed using the Occupational Health Literacy Questionnaire of National Key Populations. Results The overall OHL level among the 2 022 frontline workers was 51.43%. The OHL level in the four dimensions of basic knowledge of occupational health protection, healthy work practices and behaviors, legal knowledge of occupational health, and basic skills of occupational health protection were 81.45%, 56.08%, 43.42%, and 37.59%, respectively. The OHL levels of the six key industries from high to low were electrical machinery and equipment manufacturing, healthcare, education, express delivery/food delivery, transportation, and environmental hygiene, accounted for 91.43%, 61.98%, 52.64%, 40.58%, 36.70% and 31.15% (P<0.01). The results of logistic regression analysis showed that population of Han had higher OHL level than ethnic minorities (P<0.01), married individuals had lower OHL level than unmarried individuals (P<0.05), individuals with college education or above had higher OHL level than those with junior high school education or below (P<0.01), and higher personal monthly income was associated with higher OHL levels (all P<0.05). The OHL levels of workers of environmental hygiene, transportation, education, express delivery/food delivery, and healthcare were lower than those in electrical machinery and equipment manufacturing (all P<0.01). Conclusion The OHL level among occupational populations in the six key industries in Jiulongpo District, Chongqing City, needs to be further improved. And the OHL monitoring and intervention should be focused on the occupational population of express delivery/food delivery industry, transportation, environmental hygiene, and occupational population with low income, low educated, and ethnic minorities.

Objective To evaluate the impact of chest blast injury on left ventricular function and myocardial strain with speckle tracking imaging (STI).Methods Fifty healthy New Zealand rabbits were randomly divided into 4 groups.Five rabbits without blast injury were used as a normal group,and the other rabbits were placed in specific semi-enclosed blasting environment in accordance with the different distance of the explosion.With instantaneous detonators,slight,medium and heavy chest blast injury animal models were produced and labeled as A,B,and C group (each n=15),respectively.The left ventricular function was measured with conventional echocardiography and STI.The longitudinal strain (LS) of the left ventricle was measured with two-dimensional strain analysis software and statistically analyzed.Results There was no significant difference of ejection fraction (EF) and fractional shortening (FS) in the left ventricle after chest blast injury between group A and normal group (all P＞0.05),while LS of anterior wall,anterior septum wall and lateral wall of group A significantly decreased compared with those of normal group (all P＜0.05).In group B and C,the left ventricular EF,FS and LS of each segment were lower than those of normal group (all P＜0.05).In group C,the left ventricular EF,FS and LS of each segment were lower than those in group A (all P＜0.05).There was no significant difference of EF and FS between group B and group C.In group C,LS of anterior wall and lateral wall of basal segment and middle segment were lower than those of group B (all P＜0.05).Conclusion STI can reflect functional changes of left ventricle in each segment earlier and more sensitively after chest blast injury.
