Objective: To investigate the resistance of Mycobacterium tuberculosis to first-line anti-tuberculosis drugs in Jiaxing City, Zhejiang Province from 2017 to 2019, so as to provide insights into improvements of the therapeutic effect of pulmonary tuberculosis. Methods: Data pertaining to pulmonary tuberculosis in Jiaxing City from 2017 to 2019 were collected from the Tuberculosis Surveillance System of Chinese Disease Prevention and Control Information System, including demographics, treatment classification, sputum culture and drug resistance. The spectrum, types and prevalence of drug resistance in M. tuberculosis to four first-line tuberculosis drugs, including isoniazid (INH), rifampicin (RFP), streptomycin (SM) and ethambutol (EMB), was analyzed using a descriptive epidemiological method. Results: A total of 1 310 M. tuberculosis isolates were cultured from pulmonary tuberculosis patients in Jiaxing City from 2017 to 2019, and there were 259 M. tuberculosis isolates that were resistant to anti-tuberculosis drugs, with an overall drug resistance rate of 19.77%. The prevalence rates of drug resistance to INH, SM, RFP and EMB were 13.36%, 11.83%, 5.50% and 3.59%, respectively. The prevalence of drug resistance was lower in M. tuberculosis isolates from treatment-naïve patients than from retreated patients (18.45% vs. 34.58%, P<0.05). M. tuberculosis isolates presented high resistance to SM (4.50%) and INH alone (4.35%), the highest resistance to INH-SM combinations (3.28%), and the highest resistance to INH+RFP+SM combinations (1.83%). Sixteen isolates were resistant to all the four drugs, with a drug resistance rate of 1.22%. The proportions of resistance to a single drug, RFP resistance, multidrug resistance and resistance to two and more drugs were 10.31%, 5.50%, 4.73% and 4.73%, respectively. In addition, the prevalence of RFP resistance among all patients and treatment-naïve patients both showed a tendency towards a rise from 2017 to 2019 (P<0.05). The prevalence of RFP resistance (7.01% vs. 3.76%) and resistance to two and more drugs (6.01% vs. 3.25%) was both higher among interprovincial mobile tuberculosis patients than among local non-mobile patients (P<0.05). Conclusions The overall prevalence of drug resistance was lower in M. tuberculosis isolates in Jiaxing City from 2017 to 2019 than in Zhejiang Province, with INH and RFP resistance as predominant types.

The quality markers (Q-markers) of traditional Chinese medicine (TCM) have become a topic of interest in TCM research in recent years. Nonetheless, there is still no consensus on how to scientifically characterize TCM Q-markers. Our study establishes an identification method for TCM Q-markers based on the analytical hierarchy process (AHP) and the entropy weight comprehensive method. By constructing an evaluation system encompassing the target layer, the factor layer and the control layer, AHP can be used to analyze the weight of three core TCM quality attributes, including effectiveness, testability and specificity. Following that, the entropy weight method is employed to analyze the specific indicators for each attribute based on the literature and experimental data. Finally, the comprehensive weight of each index is obtained by combining the two weights, and the comprehensive weight and the specific value of each component is multiplied and summed to obtain the integrated score ranking, and thereby identify the TCM Q-markers. Taking Shaoyao Gancao decoction as an example, the analysis revealed that the top 8 components are as follows: paeoniflorin > quercetin > albiflorin > glycyrrhizic acid > naringenin > liquiritin > oxypaeoniflorin > benzoylpaeoniflorin, and can be identified as Q-markers of Shaoyao Gancao decoction. This study not only provides support for the establishment of quality standards and process quality control of TCM formulae, but also provides innovative ideas and methods for quantitative evaluation and accurate identification of TCM Q-markers.

OBJECTIVE Oxidative sress is one of the key factor responsible for occurrence and development of hepatic fibrosis, a common consequence of chronic liver injury of multiple etiology. Nuclear factor erythroid 2-related factor 2 (Nrf2) serves as a major regulator of a celular defense system against oxidative stress. Xiaochaihutang (XCHT), a compound of seven botanical extracts used for liver diseases traditionally in East Asia. However, few studies have investigated its anti-hepatic fibrosis effects and pathophysiological mechanism of action. The present study was designed to confirm the anti-hepatic fibrosis effects and explore its potential mechanism of action by investigating the intervention of Nrf2 pathway. METHODS Liver fibrosis was induced by repeated injection of Carbon tetrachloride (CCl4) over a period of 9 weeks. Starting from the 6th week, the animals in treatment groups were given the appropriate dose of XCHT granules and silybin. Biochemical parameters, histological changes of the liver and alpha-smooth muscle actin (α-SMA) were determined. The expressions of Nrf2, Keap1, Nqo1, HO-1, Gclc and Gclm were assessed by RT-PCR and Western blot. RESULTS CCl4 caused a significant fibrosis damage in the rat liver and the liver functions and fibrosis degree were significantly improved by XCHT (5 g·kg- 1 and 10 g·kg- 1). XCHT (5 g·kg- 1 and 10 g·kg- 1) treatment significantly decreased the number of cells labeled with α-SMA antibodies. Moreover, XCHT (5 g·kg-1 and 10 g·kg-1) significantly increase Nqo1, HO-1, Gclc and Gclm expressions in the liver. CONCLUSION These studies establish XCHT is a potentially useful therapeutic agent for treatment of hepatic fibrosis and it might be via regulation of Nrf2 pathway in rats against oxidative stress, making further efforts to inhibiting the activated HSCs. Activation or up-regulation of Nrf2 pathway may be an alternative treatment strategy for liver fibrosis.
