[Drug clinical comprehensive evaluation of tetrandrine in the treatment of pneumoconiosis].

Objective: To analyze the safety, effectiveness, economics, innovation, suitability and accessibility of tetrandrine in the treatment of pneumoconiosis, and provide evidence-based basis for health policy decision-making and clinical practice. Methods: In July 2022, the system searched PubMed, Embase, the Cochrane Library, CNKI, Wanfang, SinoMed databases (the retrieval time was from the establishment of the database to June 30, 2022), screened the documents that meet the standards, extracted and evaluated the data, and used the "HTA checklist" developed by the International Network of Agencies for Health Technology Assessment (INAHTA) to evaluate the HTA report. AMSTAR-2 Scale was used to evaluate the quality of systematic evaluation/Meta analysis. CHEERS Scale was used to evaluate the quality of pharmacoeconomics research. The included cohort study or case-control study was evaluated with the Newcastle-Ottawa Scale. The included randomized controlled trial (RCT) studies were evaluated using the Cochrane Risk Bias Assessment Tool (Cochrane RCT) quality evaluation criteria. Comprehensive comparison and analysis based on the characteristics of the data included in the study. Results: A total of 882 related literatures were detected from the initial screening. According to relevant standards, 8 RCT studies were finally selected for analysis. Statistical results showed that basic treatment with tetrandrine could better improve FEV(1) (MD=0.13, 95%CI: 0.06-0.20, P<0.001), FEV(1)/FVC (MD=4.48, 95%CI: 0.61-8.35, P=0.02) and clinical treatment efficiency. Tetrandrine had a low incidence of adverse reactions. The affordability coefficient of tetrandrine tablets was 0.295-0.492. Conclusion: Tetrandrine can improve the clinical symptoms and pulmonary ventilation function of pneumoconiosis patients, most of the adverse reactions are mild, and the clinical application is safe.

Clinical efficacy of comprehensive therapy based on traditional Chinese medicine patterns on patients with pneumoconiosis: a pilot double-blind, randomized, and placebo-controlled study.

Effective therapy options for pneumoconiosis are lacking. Traditional Chinese medicine (TCM) presents a favorable prospect in the treatment of pneumoconiosis. A pilot study on TCM syndrome differentiation can evaluate the clinical efficacy and safety of TCM and lay a foundation for further clinical research. A double-blind, randomized, and placebo-controlled trial was conducted for 24 weeks, in which 96 patients with pneumoconiosis were randomly divided into the control and treatment groups. Symptomatic treatment was conducted for the two groups. The treatment group was treated with TCM syndrome differentiation, and the control group was treated with placebo. The primary outcomes were the six-minute walking distance (6MWD) and the St. George Respiratory Questionnaire (SGRQ) score. The secondary outcomes were the modified British Medical Research Council Dyspnea Scale (mMRC), Chronic Obstructive Pulmonary Disease Assessment Test (CAT), Hospital Anxiety and Depression Scale (HADS), and pulmonary function. Only 83 patients from the 96 patients with pneumoconiosis finished the study. For the primary outcome, compared with the control groups, the treatment group showed a significantly increased 6MWD (407.90 m vs. 499.51 m; 95% confidence interval (CI) 47.25 to 135.97; P < 0.001) and improved SGRQ total score (44.48 vs. 25.67; 95% CI -27.87 to -9.74; P < 0.001). The treatment group also significantly improved compared with the control group on mMRC score (1.4 vs. 0.74; 95% CI -1.08 to -0.23; P =0.003), CAT score (18.40 vs. 14.65; 95% CI -7.07 to -0.43; P =0.027), and the total symptom score (7.90 vs. 5.14; 95% CI -4.40 to -1.12; P < 0.001). No serious adverse events occurred. This study showed that TCM syndrome differentiation and treatment had a favorable impact on the exercise endurance and quality of life of patients with pneumoconiosis.

[Efficiency of aerosol therapy in rehabilitation programs for patients with occupational broncho-pulmonary diseases].

The authors demonstrated efficiency of aerosol therapy using "Dovolenskaya" mineral water in treating patients with occupational pulmonary diseases. Results are improved bronchial drainage, normal pro- and antioxidant status, lower inflammatory activity in patients with pneumoconiosis and occupational dust bronchitis.

[Effect of methionine, retinol, tocopherol and pyridoxine on fibrogenesis in the lungs and vitamin metabolism in rats in an anthracosis model]. / Vliianie metionina, retinola, tokoferola i piridoksina na fibrogenez v legkikh i metabolizm vitaminov u krys s model'iu antrakoza.

It has been discovered in rat experiments that the diet containing an additional amount of methionine and pyridoxine and optimal quantity of fat favoured to a certain degree the retardation of the development of pulmonary fibrosis and reduced the disorders in metabolism of vitamins, characteristic for animals with experimental anthracosis. On the contrary, introduction of an additional amount of retinol into the above complex aggravated the development of pulmonary fibrosis and alterations in vitamin metabolism. At the same time the negative manifestations seen in the animals with experimental anthracosis were removed to a certain measure by administering additional doses of vitamin E.
