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.

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.

Osteoarthritis (OA) causes chronic pain that significantly impairs quality of life, with current treatments often proving insufficient and accompanied by adverse effects. Recent research has identified the dorsal root ganglion (DRG) and its resident macrophages as crucial mediators of chronic OA pain through neuroinflammation driven by macrophage polarization. We present a novel injectable thermo-sensitive hydrogel system, KAF@PLEL, designed to deliver an anti-inflammatory peptide (KAF) specifically to the DRG. This biodegradable hydrogel enables sustained KAF release, promoting the reprogramming of DRG macrophages from pro-inflammatory to anti-inflammatory phenotypes. Through comprehensive in vitro and in vivo studies, we evaluated the hydrogel's biocompatibility, effects on macrophage polarization, and therapeutic efficacy in chronic OA pain management. The system demonstrated significant capabilities in preserving macrophage mitochondrial function, suppressing neuroinflammation, alleviating chronic OA pain, reducing cartilage degradation, and improving motor function in OA rat models. The sustained-release properties of KAF@PLEL enabled prolonged therapeutic effects while minimizing systemic exposure and side effects. These findings suggest that KAF@PLEL represents a promising therapeutic approach for improving outcomes in OA patients through targeted, sustained treatment.

The STAR tool was used to evaluate and analyze the science, transparency, and applicability of Chinese pathology guidelines and consensus published in medical journals in 2022. There were a total of 18 pathology guidelines and consensuses published in 2022, including 1 guideline and 17 consensuses. The results showed that the guideline score was 21.83 points, lower than the overall guideline average (43.4 points). Consensus ratings scored an average of 27.87 points, on par with the overall consensus level (28.3 points). Areas that scored above the overall level were "conflict of interest" and "working groups", while areas that scored below the overall level were "proposals", "funding", "evidence", "consensus approaches" and "accessibility". To sum up, the formulation of pathology guidelines and consensuses in 2022 is not standardized, and the evidence retrieval process, evidence evaluation methods and grading criteria for recommendations on clinical issues are not provided in the formulation process; the process and method for reaching consensus are not provided, the plan is lacking, and registration is not carried out. It is therefore suggested that guidelines/consensus makers in the field of pathology should attach importance to evidence-based medical evidence, strictly follow guideline formulation methods and processes, further improve the scientific, applicable and transparent guidelines/consensuses in the field, and better provide support for clinicians and patients.

Objective:To investigate the clinical efficacy of single-port and mini-three-port laparoscopic sleeve gastrectomy (MTP-SG) for obesity.Methods:The propensity score matching and retrospective cohort study was conducted. The clinical data of 364 obesity patients in the Chinese Obesity and Metabolic Surgery Database who were admitted to The First Affiliated Hospital of Jinan University from July 2016 to December 2023 were collected. There were 79 males and 285 females, aged (31±9)years. Of 364 patients, 67 cases undergoing single-port laparoscopic sleeve gastrectomy (SP-SG) were divided into the SP group, and 297 cases undergoing MTP-SG were divided into the MTP group. Propensity score matching was done by the 1∶1 nearest neighbor matching method. The clamp value was set as 0.1. Measurement data with normal distribution were expressed as Mean± SD, and t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M( Q1, Q1), and the rank sum test was used for comparison between groups. Count data were expressed as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of 364 patients, 126 cases were successfully matched, including 63 cases in the SP group and 63 cases in the MTP group. After propensity score matching, the confounding bias of gender, body mass, body mass index (BMI), waist circumference, waist hip ratio were eliminated between the two groups. (2) Intraoperative and post-operative conditions. Both groups of patients successfully completed laparoscopic sleeve gastrectomy. After propensity score matching, the operation time, volume of intraoperative blood loss, number of postoperative painkillers used, number of postoperative antiemetics used, duration of postoperative hospital stay, duration of total hospital stay, surgical cost, and total hospitalization cost of the 63 pati-ents in SP group were 101(90,120)minutes, 10(10,10)mL, 1.0(1.0,2.5)times, 3.0(1.0,5.0)times, 4(3,5)days, 7(5,8)days, 4.1(3.5,4.3) ten thousand yuan, and (6.4±0.8) ten thousand yuan, respectively. The above indicators of the 27 patients in MTP group were 100(90,120)minutes, 10(10,15)mL, 2.0(1.0,4.0)times, 4.0(3.0,5.0)times, 3(3,4)days, 5(5,6)days, 3.2(2.8,4.2) ten thousand yuan, and (5.8±0.8) ten thousand yuan, respectively. There were significant differences in number of postoperative antiemetics used, duration of postoperative hospital stay, duration of total hospital stay and total hospitalization cost between the two groups ( Z=-2.39, -3.93, -3.03, t=4.04, P<0.05), and there was no significant difference in operation time, volume of intraoperative blood loss, number of post-operative painkillers used and surgical cost between the two groups ( Z=-0.49, -1.00, -1.23, -1.47, P>0.05). (3) Follow-up. One hundred and ninety five of the 364 patients conducted postoperative 1 month follow-up, including 25 patients in the SP group and 170 patients in the MTP group, and no patient experienced complications such as gastric leakage, infection, or incisional hernia. Both groups of patients had good surgical incisions. After propensity score matching, the change in BMI (ΔBMI), percentage of total weight loss (%TWL), and percentage of excess weight loss (%EWL) of 24 patients in the SP group were (3.7±1.4)kg/m 2, 11.0%±3.0%, 52.6%±30.0%, respectively. The above indicators of 40 patients in the MTP group were (4.1±1.3)kg/m 2, 11.1%±2.8%, 41.8%±19.1%, respectively. Patients who conducted the postoperative 12 month follow-up were 21 and 131 in the SP group and the MTP group, respectively. After propensity score matching, the ΔBMI, %TWL and %EWL of 15 patients in the SP group were (8.7±4.1)kg/m 2, 26.2%±9.8%, 130.0%±45.1%, respectively. The above indicators of 36 patients in the MTP group were (9.8±4.0)kg/m 2, 27.2%± 8.7%, 107.1%±40.7%, respectively. Conclusion:Both SP-SG and MTP-SG can be used to treat obesity patients and achieve satisfactory short-term results.
