Objective To study the association of early prognosis and risk factors about early neurological deterioration (END) in aged patients with cerebral hemorrhage in basal ganglia. Methods One hundred and thirty-nine aged patients with cerebral hemorrhage in basal ganglia were selected. The patients were divided into END group (59 cases) and non-END group (80 cases), the clinical data were retrospectively analyzed. The patients were followed up 3 months after discharge, the prognosis was evaluated by modified Rankin scale. Logistic regression analysis was used to determine the independent risk factors of END. Results The incidence of END was 42.4%(59/139). The incidence of unfavourable prognosis in END group was significantly higher than that in non-END group:78.0%(46/59) vs. 30.0%(24/80), and there was statistical difference (P<0.05). The score of Canadian stroke scale (CSS) at admission in END group was significantly lower than that in non-END group: (5.2 ± 2.1) scores vs. (6.9 ± 1.7) scores, but the white blood cell count at admission, hematoma volume and brain ventricle hemorrhage rate were significantly higher than those in non-END group: (10.7 ± 2.9) × 109/L vs. (7.9 ± 2.4) × 109/L, (17.4 ± 14.9) ml vs. (11.2 ± 10.5) ml and 42.4%(25/59) vs. 18.8%(15/80), and there were statistical differences (P < 0.05). There were no statistical differences in sex, age, systolic blood pressure, diastolic blood pressure, body temperature, random blood glucose, fibrinogen, activated partial thromboplastin time, prothrombin time and the incidences of hypertension, smoking history, stroke, diabetes mellitus, hyperlipidemia between 2 groups (P>0.05). The Logistic regression analysis results showed that brain ventricle hemorrhage and white blood cell count at admission were independent risks factor for END in aged patients with cerebral hemorrhage in basal ganglia(P < 0.05 or < 0.01). Conclusions The aged patients with cerebral hemorrhage in basal ganglia will be prone to END, the brain ventricle hemorrhage and white blood cell count at admission are independent risks factor for END, and the early prognosis is poor.

Objective To study the optimum parameters of the supercritical CO2 fluid extraction of Polyrhachis vicina Roger and chemical constituents of ant oil. Methods The experiments were designed with the uniform design. Three factors are extraction pressure, temperature and time. GC-MS was applied for analyzising. Results The optimum condition was obtained:the extraction pressure is 36 MPa, the temperature of extraction is 40 ℃ and extraction time is 50min. 45 components were identified from 60 chromatographic peaks. The main chemical constituents were (Z)-9-octadecenoicacid (48.278%), hexadecanoicacid (17.574%), (Z)-9-hexadecenoi (4.912%), cholesterol (2.957%). There are some linear paraffin in ant oil. Conclusion This method can extract the ant oil from Polyrhachis vicina Roger quickly and efficiently. This experiment provide foundation for exploitation and utilization of ant resource.

AIM: To optimize the spray-drying process of Qingxiang Tablets. METHODS: Excipients were selected in terms of hygroscopicity and yield rate of dried powders with several excipients added;then,the process parameters,such as the relative density of fluid extracts,intake temperature,and the input speed of liquid feedstock were optimized by orthogonal experiment,in which the transfer rate of peoniflorin,a constituent in the formulation,and dried powder yield rate were set up as the evaluation index. RESULTS: The optimal processing conditions were obtained and validated as follows: relative density of liquid feedstock was 1.12 mg/mL(containing 6%?-CD),the input speed was 10 mL/min and intake temperature was at 190 ?C. CONCLUSION: The optimal process is stable and the experimental results provide the basis of industrial production.

Objective:To study the effects of glucose,mannose and galactose on CAP10 promoter activity of Cryptococcus neoformans capsule-associated gene.Methods: Yeast cells were transfected with plasmid containing a 951 bp length of 5′ upstream flanking sequence of CAP10 coding region and a reporter gene,chloramphenicol acetyl transferase(CAT);the transfectants were treated with different concentrations(10,20,40,60,80 mg/ml) of glucose,mannose and galactose.CAT activity was assessed by ELISA method and CAT activities of different groups were compared.Results: Different concentrations of glucose and mannose had no obvious influence on CAT activity;different concentrations of galactose had obvious influence on CAT activity and the influence was positively dependent with its dose within the experimental concentration range.Conclusion: Glucose and mannose have no obvious effect on the activity of CAP10 promoter;galactose has obvious inductive effect on activity of CAP10 promoter,suggesting that CAP10 gene might be related with galactose metabolism.

Immunosuppressive tumor microenvironment is a part of the tumor microenvironment that plays an immunosuppressive function.It consists of suppressor cells and inhibitory cytokines.In recent years,be-cause of its important role in tumor immunity,CAR-T and PD-1/PD-L1 signal pathway has become a hot top-ic of immunotherapy, which can suppress immune through different mechanisms to promote tumor progression. Therefore,taking more effective anti-tumor therapies against the above mechanisms is possible to rescue the pro-gress of tumor.In this article,the influence of immunosuppression microenvironment in CAR-T cell therapy and PD-1/PD-L1 signaling pathway in the anti-tumor process is reviewed.

Objective To explore value of two-dimensional speckle tracking imaging (2D-STI) strain parameters in assessment of left ventricular (LV) dyssynchrony and its relationship with cardiac function in patients with dilated cardiomyopathy (DCM).Methods Totally 25 patients with DCM and 25 age-matched normal controls were enrolled.The LV time to peak longitudinal strain (Tls) and time to peak circumferential strain (Tcs) were measured by 2D-STI,from which the standard deviations and maximal differences of the Tls in all 18 segments,6 segments at apical 4-chamber,3-chamber and 2 chamber views (Tls-SD,Tls-SD-4,Tls-SD-3,Tls SD-2,Tls dif,Tls-dif-4,Tls-dif-3,Tls-dif-2) were calculated,as same as the standard deviations and maximal differences of Tcs in all 18 segments,6 segments at mitral valve,papillary muscle,apical short-axis views (Tcs-SD,Tcs-SD-M,Tcs-SD-P,Tcs-SD-A,Tcs-dif,Tcs-dif-M,Tcs-dif-P,Tcs-dif-A) were calculated.Results Compared with the control group,the global and segmental strain parameters of the DCM group increased significantly (all P＜0.05).Except for Tcs-dif-P and Tcs dif,the residual strain parameters were negatively correlated with LV ejection fraction (all P＜0.05).Except for Tcs-dif-M,Tcs dif-P and Tcs-dif,there was a positive correlation between strain parameters and E/e in DCM group (all P ＜0.05).Conclusion In patients with DCM,LV dyssynchrony exists both in global and regional,which may aggravates the LV function damage.2D-STI strain parameters can objectively evaluate LV dyssynchrony and its relationship with cardiac function in patients with DCM.
