Objective To explore the clinical effect of escitalopram combined with xingnaojing in post-stroke depression (PSD).Methods Seventy-four cases with PSD were divided into treatment group (38 cases) and control group (36 cases) by random digits table,control group was given escitalopram,treatment group was given escitalopram and xingnaojing.Hamilton depression scale (HAMD),mental state examination (MMSE),memory quotient (MQ) and activities of daily life (ADL) score,clinical curative effect and adverse reaction were compared between 2 groups.Results The HAMD,MMSE,MQ,ADL score after treatment in 2 groups were significantly better than those before treatment [control group:(14.26 ± 2.61)scores vs.(29.73 ± 5.17) scores,(23.26 ± 3.75) scores vs.(21.24 ± 3.38) scores,(86.53 ± 6.49) scores vs.(82.35 ± 5.42) scores,(61.37 ± 3.72) scores vs.(45.32 ±4.48) scores;treatment group:(10.31 ± 2.08)scores vs.(29.57 ± 6.09) scores,(27.83 ± 4.31) scores vs.(21.63 ± 3.82) scores,(95.63 ± 6.41) scores vs.(82.30 ± 7.48) scores,(69.15 ± 6.39) scores vs.(45.27 ± 4.28) scores,P ＜ 0.05].The HAMD,MMSE,MQ,ADL score after treatment in treatment group were significantly better than those in control group (P ＜0.05).The total effective rate in treatment group was significantly higher than that in control group [97.4％(37/38) vs.86.1％(31/36),P ＜ 0.05].There was no significant difference in rate of adverse reaction between 2 groups (P＞ 0.05).Conclusion Escitalopram combined with xingnaojing in PSD is effective and safe,and worth further clinical application promotion.

Objective To analyze the clinical characteristics and factors influencing adverse treatment outcomes in elderly patients with multidrug-resistant pulmonary tuberculosis (MDR-TB) to guide the clinical diagnosis and treatment of elderly MDR-TB patients. Methods Clinical data of elderly patients with multidrug-resistant pulmonary tuberculosis initially treated at Beijing Chest Hospital from 2008 to 2023 were retrospectively collected. Complications/comorbidities, adverse drug reactions, drug resistance during initial treatment, and retreatment were statistically described. Factors influencing adverse treatment outcomes were analyzed using the chi-square test and logistic regression analysis. Results A total of 238 elderly patients with MDR-TB were collected, of which 152 (63.9%) had adverse drug reactions, 184 (77.3%) were retreated MDR-TB, 27 (11.3%) were extensively drug-resistant tuberculosis (XDR-TB), 41 were cured, 6 completed treatment, 39 failed treatment, 6 died, 107 lost to follow-up, 31 could not be evaluated, 8 did not finish treatment, and the treatment success rate was 20.4% (47/230). The adverse outcome of treatment accounted for 79.6% (183/230). Univariate analysis showed that differences in age groups, the occurrence of drug adverse reactions, and patient sources had a statistically significant impact on treatment outcomes (P<0.05). Logistic regression analysis was performed using good and adverse treatment outcomes as dependent variables for the three factors, which showed that being aged 70 and above, the occurrence of drug adverse reactions during treatment, and being a non-local patient were factors influencing adverse treatment outcomes [OR (95%CI): 2.507 (1.027-6.121), 3.253 (1.635-6.473), 2.563 (1.285-5.111), respectively]. Conclusions Elderly patients with MDR-TB exhibit a high prevalence of complications/comorbidities, a high incidence of drug adverse reactions, and unfavorable treatment outcomes. Out-of-town medical treatment, advanced age, and experiencing drug adverse reactions are risk factors for adverse treatment outcomes.

Heme is a key cofactor in aerobic life, both in eukaryotes and prokaryotes. Because of the high reactivity of ferrous protoporphyrin IX, the reactions of heme in cells are often carried out through heme-protein complexes. Traditionally studies of heme-binding proteins have been approached on a case by case basis, thus there is a limited global view of the distribution of heme-binding proteins in different cells or tissues. The procedure described here is aimed at profiling heme-binding proteins in mouse tissues sequentially by 1) purification of heme-binding proteins by heme-agarose, an affinity chromatographic resin; 2) isolation of heme-binding proteins by SDS-PAGE or two-dimensional electrophoresis; 3) identification of heme-binding proteins by mass spectrometry. In five mouse tissues, over 600 protein spots were visualized on 2-DE gel stained by Commassie blue and 154 proteins were identified by MALDI-TOF, in which most proteins belong to heme related. This methodology makes it possible to globally characterize the heme-binding proteins in a biological system.
