Objective To comparatively study the advantage and disadvantage of different polysaccharide extraction methods of enzymatic extraction,ultrasonic extraction and a combination of these two processes.Methods The enzymatic extraction and ultrasonic extraction were first optimized by orthogonal design and then compared with the effect of combination.Results From the results of three extraction techniques,enzymatic extraction of Talinum crassifolium polysaccharide's average extraction rate was 17.45％,ultrasonic extraction was 20.01％,enzyme-ultrasonic extraction was 20.74％.Conclusion The combined optimum preparative procedure of Talinum crassifolium is simple,quickly and high efficient.

Objective To explore the value of waring score of potential critical disease in predicting changes in condition of patients with multiple injuries. Methods From January 1, 2013 to July 31, 2013, all patients with multiple injuries were included prospectively. Patients were observed as soon as ICU admission. The waring score of potential critical disease and MEWS of all patients and the rates of changes in condition of patients were calculated then statistic analysis was performed. Results Of 50 patients enrolled, 44 were survived and 6 were died and 295 changes were found. The maximum , minimum median (P25, P75) of waring score of potential critical disease were 22, 0, 5 (3, 7). The maximum, minimum median (P25, P75) of MEWS were 12, 0, 4 (2, 6). The area under the ROC of waring score of potential critical disease was 0.880 (95% CI, 0.813-0.947, P < 0.001). Youden index was the biggest when waring score of potential critical disease was 6.5. The area under the ROC of MEWS was 0.767 (95% CI, 0.661-0.873, P < 0.001). Youden index was the biggest when MEWS was 5.5. Conclusion The waring score of potential critical disease was effective to predict changes in conditions of patients with multiple injuries and better than MEWS.

Objective:To investigate the safety and efficacy of robot-guided ventricular partition puncture drainage in severe intraventricular hemorrhage.Methods:A total of 23 patients with severe intraventricular hemorrhage who underwent robot-guided ventricular partition puncture drainage (experimental group) and 19 patients who underwent robot-guided bilateral ventricular puncture drainage (control group) at Department of Neurosurgery, People's Hospital of Baise from January 2021 to December 2021 were included. The differences in residual hematoma volume within 24 h of surgery, drainage tube retention time, mortality rate within 30 d of surgery, incidence of complications (re-bleeding, intracranial infection, pulmonary infection, hydrocephalus) within 6 months of surgery, and scores of Glasgow coma scale (GCS), activity of daily living (ADL), and National Institutes of Health stroke scale (NIHSS) at 6 months after surgery were compared between the 2 groups.Results:Compared with the control group, the experimental group had significantly lower residual hematoma volume within 24 h of surgery ([8.854±3.519] mL vs. [5.668±2.873] mL), shorter drainage tube retention time ([6.580±1.981] d vs. [4.910±2.763] d), lower incidence of hydrocephalus within 6 months of surgery (42.105% vs. 8.696%), and significantly higher GCS and ADL scores and lower NIHSS scores at 6 months after surgery (8.790±2.898 vs. 11.610±2.948; 69.470±12.899 vs. 78.480±12.861; 13.950±5.265 vs. 9.870±4.124, P<0.05). Conclusion:Robot-guided ventricular partition puncture drainage is a safe and effective surgical method for severe intraventricular hemorrhage.
