Based on mass spectrometry(MS)-guided separation strategy, compound 1 was obtained from the roots of Rhus chinensis. By comprehensive analysis of high resolution-electrospray ionization-mass spectrometry(HR-ESI-MS), nuclear magnetic resonance(NMR) data, and quantum chemical calculation of NMR(qcc-NMR) parameters, compound 1 was elucidated as rhuslactone, a 17-epi-dammarane triterpenoid with a rare 17α-side chain. An HPLC-ELSD method for its quantification in R. chinensis was established and adopted for the quantification of rhuslactone in different batches of R. chinensis. Rhuslactone displayed a good linear relationship within the range of 0.021 3-1.07 μmol·mL~(-1 )(r=0.997 6), and the average recovery was 99.34% [relative standard deviation(RSD) 2.9%). Moreover, the results of the evaluation test of the preventive effects of rhusalctone on coronary heart disease(CHD) and thrombosis showed that rhuslactone(0.11 nmol·mL~(-1)) significantly alleviated heart enlargement and venous congestion and increased cardiac output(CO), blood flow velocity(BFV), and heart rate, thereby reducing thrombus formation in zebrafish with CHD. The effects of rhuslactone on CO and BFV were superior to that of digoxin(1.02 nmol·mL~(-1)), and its effect on improving heart rate was comparable to that of digoxin. This study provides experimental references for the isolation, identification, quality control, and application of rhuslactone from R. chinensis against CHD. It is worth mentioning that this study has discussed some omissions in the determination of the stereochemistry of C-17 in dammarane triterpenoids in the present coursebook Chemistry of Chinese Medicine and some research papers, that is, the compound may be 17-epi-dammarane triterpenoid. This paper has also proposed steps for the establishment of C-17 stereochemistry.

Abstract: The loop-mediated isothermal amplification (LAMP) technique is a technique for the specific and efficient amplification of target fragments at a constant temperature using two pairs of specially designed primers and a strand displacement activity DNA polymerase. LAMP technique is a simple, rapid, specific, sensitive and cost-effective nucleic acid amplification method, and therefore has a promising future in the field rapid detection of Mycobacterium tuberculosis and grassroots applications. In this review, the basic principles and characteristics of the LAMP technique, the main molecular markers for the diagnosis of tuberculosis, and the use of different molecular markers and various types of novel techniques in the diagnosis of pulmonary tuberculosis, extrapulmonary tuberculosis, and drug-resistant tuberculosis were described. The LAMP technique has been widely used in the diagnosis of tuberculosis with high sensitivity and specificity, but the technique still has some shortcomings. This paper reviews the progress of its application in tuberculosis in recent years and provides an outlook on its development, with a view to providing a rational research direction for rapid diagnosis of tuberculosis in a resource-limited environment.

Through the combing of ancient books of Chinese herbal medicine in the past dynasties, a textual research of Coptidis Rhizoma involved the name, origin, medicinal parts, producing area, quality evaluation, harvesting and processing methods in famous classical formulas was conducted in this paper. After textual research, the mainstream varieties of Coptidis Rhizoma in the Ranunculaceae family before Tang and Song dynasties were Coptis chinensis and C. chinensis var. brevisepala, after the Ming and Qing dynasties, C. deltoidea, C. teeta and C. omeiensis were gradually praised. In ancient times, the authentic producing area of Coptidis Rhizoma has the characteristics of gradually moving to the west. The eastern Coptidis Rhizoma was highly praised in the early stage, while in the later stage, western Coptidis Rhizoma like chicken feet was highly praised. In the early stage, western Coptidis Rhizoma probably originated from C. chinensis and its genus, while Coptidis Rhizoma like chicken feet was cultivated, and no wild species has been found so far. As Coptidis Rhizoma has mixed use of multiple origins in ancient books of past dynasties, based on the current shortage of market resources in C. teeta and C. deltoidea, there are also endangered and protected plants of C. chinensis var. brevisepala and C. omeiensis, combined with the mainstream medicines and resources of past generations, it is recommended to choose C. chinensis as the base of the formulas. In ancient times, there were many processing methods for Coptidis Rhizoma, such as frying and wine-, ginger-, honey-processed. In the process of developing famous classical formulas, the appropriate processing specifications of Coptidis Rhizoma should be selected based on the original source records and the requirements of the medicinal material.

Patrinia villosa, regarding its functions in clearing heat and detoxification and eliminating carbuncles and pus, is widely used as a traditional medicinal herb that contains rich nutrition and substances such as various amino acids, vitamins, and soluble su-gar, and it is also an edible wild herb in Chinese folk tradition for 2 000 years. In 1973, Japanese scholars firstly separated three iridoids from Japanese P. villosa, and by 2021, chemical components such as flavonoids, iridoids, organic acids, triterpenoids, phenylpropanoids, and steroids have been found, which have multiple pharmacological effects, including antioxidant, antitumor, anti-diarrhea, antibacterial, sedative, and liver protection capabilities. Studies indicate that flavonoids, saponins, phenylpropanoids, and triterpenoids in P. villosa are vital substances for its pharmacological activities. However, the quality of this medicinal material cannot be controlled due to the unclear records in ancient books in the past dynasties and different drug use habits in different places, and thus its circulation is chaotic. At present, researchers have used flavonoids, organic acids, phenylpropanoids, triterpenoid saponins, and other compounds to conduct studies in this regard. Therefore, on the basis of the existing literature resources, we comprehensively summarize the chemical constituents, pharmacological activities, and quality control of P. villosa to further provide a reference for the safety and effectiveness of clinical drug use and lay a foundation for the follow-up experimental research.

OBJECTIVE: To analyze the current status of silica dust hazard in workplaces of Jiangxi Province. METHODS: The level of silica dust in the air of workplaces, occupational health examination of the dust-exposed workers and diagnosis of occupational disease in 1 557 enterprises in Jiangxi Province were investigated and analyzed. RESULTS: The 1 557 enterprises were included in eight industries, and the main types of enterprises were non-coal mining, ceramic products manufacturing and stone processing industry(a total of 85.16%). There were 4 029 jobs/positions that were involved in exposure to silica dust in these workplaces. Among them, the exposure concentration of time weighted average(C_(TWA)) of total dust and respirable dust exceeded 21.52% and 20.55%, respectively. The posts where the total dust and respirable dust that exceed the standard were found in the quartz sand processing industry, non-ferrous metal smelting industry and stone processing industry, that were the top three among the eight industries(all P<0.01). Among the 828 posts with C_(TWA) of respiratory dust exceeding the standard, the C_(TWA) exceeding rate of mild-, moderate-and high-hazardous jobs were 3.87%(156/4 029), 1.66%(67/4 029) and 15.02%(605/4 029), respectively. Among 23 643 dust-exposed workers, the detection rates of occupational contraindications and suspected silicosis were 2.06% and 1.51%, and the prevalence of silicosis was 1.21%. CONCLUSION: Silica dust hazard in workplaces of quartz sand processing industry, non-ferrous metal smelting industry and stone processing industry are serious in Jiangxi Province. The supervision and management of occupational health should be further strengthened to guarantee the occupational health of workers.

Objective: To evaluate the model with spleen deficiency and dampness stagnancy by bioelectrical impedance analysis (BIA) and traditional indicators. Method: The forty rats were divided into blank group and model group, with 20 rats in each group. The rats in the blank group were fed with normal feed, the rats in model group were prepared with the spleen deficiency and dampness stagnancy model for 14 days. Observe the general condition of the rats, measure the water content of the feces in the dry method, measure the water load index by weighing method, and detect the urinary D-xylose excretion total protein (TP), albumin (Alb) content, by enzyme-linked immunosorbent assay (ELISA). Western blot analysis of renal aquaporin 1 (AQP1) content, and the use of experimental animal body composition analyzer to determine the total water content (TBW), extracellular fluid (ECF), intracellular fluid (ICF), fat mass (FM), free fat mass (FFM) and body mass bioelectrical impedance index such as body mass index (BMI). Result: Compared with blank group, the rats in model group lost weight, gradually loose stools occasionally, the anus temperature was basically unchanged, body mass, D-xylose excretion, water load index, TP and Alb content decreased (P<0.01). The feces contained water,the rate and the content of AQP1 in the renal pulp were increased (P<0.01). The TBW, ECF and FFM were increased, and the ICF, FM and BMI were decreased (P<0.01). Conclusion: Rats with spleen deficiency and dampness stagnancy induced a combination of factors such as diet and excessive fatigue. The bioelectrical impedance method can be more intuitive and comprehensive.
