Prescription optimization is a crucial aspect in the study of traditional Chinese medicine (TCM) compounds. In recent years, the introduction of mathematical methods, data mining techniques, and artificial neural networks has provided new tools for elucidating the compatibility rules of TCM compounds. The study of TCM compounds involves numerous variables, including the proportions of different herbs, the specific extraction parts of each ingredient, and the interactions among multiple components. These factors together create a complex nonlinear dose-effect relationship. In this context, it is essential to identify methods that suit the characteristics of TCM compounds and can leverage their advantages for effective application in new drug development. This paper provided a comprehensive review of the cutting-edge optimization experimental design methods applied in recent studies of TCM compound compatibilities. The key technical issues, such as the optimization of source material selection, dosage optimization of compatible herbs, and multi-objective optimization indicators, were discussed. Furthermore, the evaluation methods for component effects were summarized during the optimization process, so as to provide scientific and practical foundations for innovative research in TCM and the development of new drugs based on TCM compounds.

ObjectiveTo establish an adjusted Serfling regression model to estimate the excess cases and the excess epidemic period of hand-foot-mouth disease (HFMD) in Beijing from 2011 to 2019, so as to provide data support and decision-making basis for HFMD prevention and control. MethodsThe weekly number of HFMD cases in Beijing from 2011 to 2019 was utilized for adjusted the Serfling regression model. Then the adjusted model was used to fit the baseline and epidemic threshold of HFMD in Beijing from 2011 to 2019, calculating the excess cases and determining the excess epidemic period. ResultsA total of 279 306 cases of HFMD were reported in Beijing from 2011 to 2019, with the climax of the disease occurring in summer and autumn. After adjusting the fitting R2 of the Serfling regression model to 0.773, a total of 10 excess epidemic periods totaling 92 weeks were estimated, mainly occurring in summer. The highest number of excess cases during an excess epidemic period was found in 2014 (1 272 cases, 95%CI: 990‒1 554), accounting for 65.04% of the actual cases (95%CI: 50.62%‒79.46%). ConclusionThe adjusted Serfling regression model fits well and can be utilized for early warning of HFMD and estimating the disease burden caused by HFMD.

Objective To investigate the reproductive and developmental effects of Clothianidin in rats. Methods Clothianidin was administrated by diet to both parental and first filial (F 1) generations of rats at the dosages of 0, 30.51, 110.84 and 304.26 mg/(kg·d) in females, and 0, 26.45, 92.69 and 279.42 mg/(kg·d) in males. Clothianidin was administered through diet to male and female rats for 8 weeks before mating. Clothianidin was administered to female rats in the parental and F1 generations during mating, gestation and lactation periods. During the test, toxicity performance was observed, reproduction index was calculated, and pathological examination was carried out. Results The body weights of rats in the parent and F1 generations in the high-dose group were lower than those in the control group during pre-mating exposure and at various time points during pregnancy and lactation (P<0.05). The pregnancy rates of parental and F1 generations in the high-dose group were lower than those of the control group (48.57% vs 71.43%, 45.71% vs 80.00%, P<0. 05). Sperm concentration and sperm motility of the parental generation were lower than those of the control group [(42.55±12.87) vs (53.84±7.65) ×106/ml, (58.94±10.59) vs (65.59±6.03), (P<0.05)]. Sperm concentration and sperm motility of the F1 generation were lower than those of the control group [(41.64±12.42) vs (53.09±9.48), (55.13±9.19) vs (64.53±6.31), (P<0.05). Conclusion Exposure to clothianidin has reproductive toxicity to Wistar rats, and the no-observed adverse effect level (NOAEL) in the two-generation reproductive toxicity test is 92.69 mg/kg·BW for males and 110.84 mg/kg·BW for females in Wistar rats.

As a common medical condition, vertigo can be induced by multiple diseases in the modern medical system. Its incidence rate shows an upward trend with the increase in age. According to the theory of mutual interference between clear Qi and turbid Qi in Huangdi's Internal Classic (Huang Di Nei Jing), this paper systematically analyzes the pathogenesis of vertigo and explores the mechanism and clinical application value of Xiao Chaihutang in the treatment of vertigo. It is believed that the mutual inference between clear Qi and turbid Qi leads to the failure of clear Yang to ascend, resulting in the lack of nourishment for the brain and the inability of turbid Yin to descend, which disturbs the clear orifices, thus causing vertigo. The core pathogenesis lies in the dysfunction of Qi movement, the disorder of body fluid distribution, and the imbalance between Yin and Yang. The compatibility of Xiao Chaihutang takes into account the methods of pungent medicinal materials opening and bitter medicinal materials descending, tonifying deficiency and purging excess, and regulating Qi movement. This prescription can regulate the pathological state of the mutual interference between clear Qi and turbid Qi from three aspects: regulating Qi movement throughout the body, harmonizing the distribution of body fluids, and coordinating Yin and Yang as well as the interior and exterior, thus preventing and treating vertigo. Modern research findings show that Xiao Chaihutang can improve hemodynamics to promote cerebral blood circulation and has anti-inflammation, immunomodulatory, and anti-tumor functions, which correspond to the therapeutic effects of Xiao Chaihutang under the theory of mutual interference between clear Qi and turbid Qi. The decoction exerts therapeutic effects on vertigo caused by hypertension, stroke, otitis media, Meniere’s disease, and brain tumor as well as benign paroxysmal positional vertigo. Further exploration of the theoretical connotation of mutual inference between clear Qi and turbid Qi and analysis of the pathogenesis of vertigo and the therapeutic effect of Xiao Chaihutang can better interpret the internal correlations among the three, thus providing new ideas for the syndrome differentiation and treatment of vertigo.

Objective To investigate the initial dose and safety of intravenous infusion of sodium (s)-2-(dithiocarboxylato((2R,3R,4R,5R,6R)-2,3,4,5,6-pentahydroxyhexyl) amino)-4-(methylthio) butanoate (GMDTC) for the displacement of cadmium. Methodsi) Efficacy test. The New Zealand male rabbits were randomly divided into model group, calcium disodium edetate (EDTA) group and GMDTC low-, medium- and high-dose groups after cadmium poisoning using 2.5 cadmium chloride dihydrate. Rabbits in EDTA group were intravenously injected with EDTA dipotassium at a dose of 93.5 mg/kg body weight, rabbits in the three doses groups were intravenously injected of GMDTC at doses of 12.0, 36.0, and 108.0 mg/kg body weight, respectively. The rabbits in the control group (separate set) and model group were intravenously injected with equal volumes of 0.9% sodium chloride solution, administered for five consecutive days per week for 1, 2, and 4 weeks. ii) Toxicity test. Specific pathogen free SD rats were randomly divided into solvent control group and low-, medium- and high-dose groups. In the acute toxicity test, the rats in the three-dose groups were intravenously injected of GMDTC at doses of 200.0, 800.0 and 3 000.0 mg/kg body weight, respectively. In the long-term toxicity test, the rats in the three-dose groups were intravenously injected GMDTC at doses of 100.0, 500.0 and 2 000.0 mg/kg body weight, respectively, once a day for four consecutive weeks, with a recovery period of four weeks. The rats in the solvent control group were given an equal volume 0.9% sodium chloride solution intravenously at the same time. The maximum tolerated dose (MTD) and no observable adverse effect level (NOAEL) were detected. Resultsi) In the one week treatment experiment, the 24 hours urinary cadmium levels of rabbits in the three doses groups were higher than those in the model group at the same time point (all P<0.05). In the two weeks treatment experiment, the 24 hours urinary cadmium levels of rabbits in medium-dose and high-dose groups at the three time points were higher than those in the model group at the same time point (all P<0.05). In the four weeks treatment experiment, the 24 hours urinary cadmium level on the 19th day of rabbits in the low-dose group was higher than that in the model group at the same time point (P<0.05), and the 24 hours urinary cadmium levels of rabbits in medium- and high-dose groups at the five time points were higher than those in the model group at the same time point (all P<0.05), except for the rabbits of fifth day of the medium-dose group. The kidney cadmium levels of rabbits in the low-dose group after four week of treatment and in the medium- and high-dose groups after one, two, and four weeks of treatment decreased compared with the model group (all P<0.05). No obvious adverse effects were observed during the treatment. ii) The MTD of GMDTC in rats administered intravenously in a single dose was 3 000.0 mg/kg body weight. During the period of intravenous infuseion with GMDTC for four consecutive weeks, the blood drug level reached the peak at the end of the first and last administrations (eight min), and no clinical adverse reactions were observed during this period of time, nor was there any apparent accumulation. The NOAEL for intravenous infusion of GMDTC for four consecutive weeks in rats was 500.0 mg/kg body weight. Conclusion The initial dose of the GMDTC injection in the cadmium poisoning rabbit was 36.0 mg/kg body weight, and the recommended initial dose for human is 480.0 mg/person. Intravenous infusion of GMDTC is characterized by rapid absorption, rapid elimination, and no accumulation.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.
