Objective To investigate the relationship of Vaneomycin serum concentration and drug adverse reactions (ADRs) in neonates.Methods Two hundred and thirteen neonates who were treated by Vancomycin and had their serum concentration monitored were recruited.The number of cases which had liver,kidney and hearing damage after treatment was calculated.The correlation between 3 different serum concentrations (＜5 mg/L,5-10 mg/L,＞ 10 mg/L) and ADRs were analyzed.Results The mean level of Vancomycin in serum was (4.36 ± 4.99) mg/L The total incidence of ADRs was 17.8％ (38/213 cases).The main ADRs were liver damage and hearing impairment,whose incidences were 9.9％ (21/213 cases) and 7.5％ (16/213 cases),respectively,and they were were significantly higher than kidney danage (0.5％,1/213 cases) (x2 =19.172,P =0.000;x2 =13.785,P =0.000).There was no significant difference be-tween the inidence ratio of liver damage and that of the hearing impairment (x2 =0.330,P =0.566).The ADRs ratio among 3 different serum concentrations was 17.0％ (24/141 cases),17.6％ (9/51 cases) and 23.8％ (5/21 cases).There was no significant difference between the ADRs ratios and distribution of different serum concentrations (x2 =0.576,P =0.750).Moreover,the ADRs rates didn't increase along with the serum concentrations (Z =0.648,P =0.517).Except for aspartate transaminase,the indicators of liver and kidney function varied significantly after vancomycin treatment (P ＜0.05).But there was no clinical significance because the mean value was in normal range.By Bivariate Correlation analysis,Vancomyein serum concentration had no significant influence on liver and kidney function (P ＞ 0.05).Conclusions Neonates treated by Vancomycin had reatively high ratio of the liver damage and the hearing impairment.There is no significant correlation between Vancomyein serum concentration and ADRs in neonates.

Objective:To optimize the matrix formulation of Erhuang analgesic gels. Methods:Central composite design-response surface methodology was adopted to optimize the best formulation of Erhuang analgesic gels by using carbomer 940, triethanolamine and glycerine as independent variables, the appearance, stability, viscosity and in vitro release of berberine hydrochloride as comprehensive evaluation indices. Results:The fitting regressing equation was Y= 82.25 + 4.95 A+ 5.19 B + 1.41 C+ 1.51 AB + 0.904 0 AC- 0.531 9 BC- 2.92 A2-1.80 B2-0.182 1 C2. P value of the model was less than 0.000 1, and the correlation coefficient r value was 0.977. The optimal formulation of Erhuang analgesic gels consisted of 1.84% carbomer 940, 1.30 times triethanolamine of carbomer 940 and 13.99 grams of glycerine. The average comprehensive scores of three verification experiments was 88.56, and the deviations from the predicted values were 2.93%, 2.85% and 1.55%. Conclusion:The formulation process by central composite design-response surface methodology was stable and the formulation of Erhuang analgesic gels has been optimized.

Objective To explore the correlation between the total burden of cerebral small vessel disease and poor prognosis of branch atheromatous disease(BAD)in elderly patients.Methods A total of 114 BAD patients admitted to Shanghai Eighth People's Hospital between January 2021 and March 2023 were enrolled,and according to mRS score at 90 d after onset,they were divided into a good prognosis group(mRS score ≤2,67 cases)and a poor prognosis group(mRS score＞2,47 cases).The clinical and imaging characteristics were analyzed,and the relationship between total cerebral small vessel disease burden and clinical prognosis of BAD was investigated using lo-gistic regression analysis.ROC curve analysis was used to determine the threshold of the total cere-bral small vessel disease burden for predicting adverse outcomes and to evaluate its sensitivity and specificity.Results The good prognosis group had younger age,smaller proportion of diabetes,lower SBP,NIHSS score at admission and white matter hyperintensities,and reduced ratio of cerebral microbleeds than the poor prognosis group(P＜0.05,P＜0.01).Statistical difference was observed in the total cerebral small vessel disease burden between the two groups(P＜0.01).Binary logistic regression analysis showed that the total cerebral small vessel disease burden score and NIHSS score at admission were independent predicators of poor prognosis in BAD patients(OR=3.350,95％CI:1.439-7.798,P=0.005;OR=2.814,95％CI:1.586-4.993,P=0.001).ROC curve analysis indicated that the total cerebral small vessel disease burden had a cut-off val-ue of 1.5,and the sensitivity and specificity for predicting poor prognosis was 63.8％and 86.6％,respectively,for BAD patients.Conclusion The total cerebral small vessel disease burden is an in-dependent predictor for poor prognosis of BAD patients.
