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.

OBJECTIVETo compare therapeutic effects of catgut implantation at acupoint and routine acupuncture on prolapse of lumbar intervertebral disc.

METHODSOne hundred and forty cases were randomly divided into a treatment group and a control group, 70 cases in each group. The treatment group were treated with catgut implantation at acupoint, once each week, 3 sessions constituting one course, and the control group with routine acupuncture, once every other day, 10 sessions constituting one course.

RESULTSThe effective rate was 95.6% after treatment of one course and 88.2% 3 months later in the treatment group, which were better than 84.6% and 72.3% in the control group, respectively (Both P < 0.05).

CONCLUSIONCatgut implantation at acupoint has a better therapeutic effect on prolapse of lumbar intervertebral disc, with lower cost.

Objective: To search for specific metabolites in the lungs of pneumonia rats fed with a high-calorie diet, as well as explore the changes in the lung metabolites of young rats treated with Yinlai Decoction (YD) and its effects on inflammation-related metabolic pathways.Methods: Lipopolysaccharides (LPS) and a special high-calorie diet were used to induce Sprague Dawley (SD) rats to simulate the intestinal state of infant pneumonia. Liquid chromatography-mass spectrometry technology (LC-MS/MS) was used to detect metabolites in each group. Supervised orthogonal partial least squares discriminant analysis (OPLS-DA) model values were used for the detection results to find the differential metabolites. The metabolic pathways that are involved with the differential metabolites were clarified through enrichment analysis and topological analysis. Finally, the T cell receptor signaling pathway (TCR) signal conversion was analyzed by the network pharmacology method. Results: In the high-calorie diet combined with pneumonia group (M3), a total of 55 metabolites were determined to be different from the normal group (N). A total of 36 metabolites were determined to be different from those in the lung metabolites of the YD treatment group (T1). YD had a regulatory effect on glutathione metabolism, arginine and proline metabolism, ascorbic acid and aldehyde metabolism and phenylalanine metabolism. And the small molecule metabolites could act on the FYN and lymphocyte-specific protein tyrosine kinase (LCK) target proteins in the TCR signaling pathway, thereby affecting the immune function of the lungs. Conclusion: A high-calorie diet can cause abnormal sphingolipid metabolism in the lungs of young rats, thereby creating chronic lung inflammation in young rats. YD has a beneficial effect when used to treat young rats with LPS-induced pneumonia fed on high-calorie diets. Its mechanisms of action may affect the body's immune pathways by regulating the oxidative stress pathway affected by glutathione metabolism.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.
