Objective:To analyze the current status of global clinical trial for botulinum toxin (BTX) drugs, and to provide a reference for BTX drug research priorities and trends.Methods:All registered BTX drug-related clinical trials from the inception of the platforms until December 2024 were retrieved from the International Clinical Trials Registry Platform (ICTRP) and the Center for Drug Evaluation (CDE) Clinical Trial Registration and Information Disclosure Platform of the National Medical Products Administration of China (referred to as the CDE Platform). The data were statistically analyzed using Excel 2021. The analysis was conducted from aspects such as registration volume and annual trend, distribution of conducting countries, drug type, study type and recruitment situation, and indications.Results:A total of 2 053 clinical trials related to BTX were included. The total number of registered trials showed an increasing trend year by year. The country with the largest number of clinical trials was the United States, with 571 trials, while China ranked third with 190 trials. Among the drug formulations, the injection form accounted for the highest proportion (99.02%, 2 033/2 053). A few new formulations included topical ointments, nasal sprays, and eye drops. In terms of drug serotypes and sources, the wild-type BTX-A projects accounted for a relatively high proportion (97.86%, 2 009/2 053), and also included a few wild-type BTX-B, wild-type BTX-E, recombinant BTX-AB, and recombinant BTX-A projects. In terms of research types, 90.4% (1 856/2 053) were intervention studies, 87.5% (1 796/2 053) of the clinical trials did not restrict gender, 90.7% (1 862/2 053) of the clinical trials recruited subjects covering adults, and 9.3% (191/2 053) of the clinical trials only recruited minors. The research indications covered various disciplines, such as skin beauty, neurology, urology, orthopedics, and ophthalmology. In recent years, the types of diseases registered for clinical trials had expanded significantly on the basis of the originally approved indications.Conclusion:Innovative directions in BTX drug research, including BTX drugs of different serotypes, recombinant BTX based on recombinant gene technology, BTX formulations for non-injectable delivery, and innovative areas of clinical application, are driving its continued clinical research.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

ObjectiveThis study aims to investigate the effectiveness and potential mechanism of Erxian Decoction （二仙汤） for late-onset depression （LOD）. MethodsForty Wistar male rats of 7-8 weeks were divided into 20 each of normal group and youth depression group. Sixty Wistar male rats of 20 months were divided into 20 each of elder group， LOD group and Erxian Decoction group. The rats in youth depression group were modelled with chronic unpredictable mild stress （CUMS） for 6 weeks to build a depression model， and the elder rats in LOD group and Erxian Decoction group were modelled with CUMS for 6 weeks to build a LOD model， with no interventions in the normal group and the elder group. Gastric administration was carried out at the same time of modelling， rats in Erxian Decoction group were given 8 g/（kg·d） of Erxian Decoction by gavage， and rats in the normal group， youth depression group， elder group， and LOD group were given 4 ml/（kg·d） of pure water by gavage， for 6 weeks in each group. Sugar water preference experiment and forced swimming experiment were used to evaluate the depression-like behaviour of rats， absent field experiment was used to evaluate the spontaneous activity ability of rats， and T-maze experiment was used to evaluate the cognitive function of rats； Western blot assay was used to detect neuronal nuclei （NeuN）， nestin， doublecortin （DCX） in hippocampal tissue， and zonula occludens-l （ZO-1）， folate receptor α （FRα）， reduced folate carrier （RFC）， and protoncoupledfolate transporter （PCFT） protein expression in choroid plexus； immunofluorescence was used to detect the number of double-positive cells for Ki-67/nestin， the number of double-positive cells for 5-bromodeoxyuracil nucleoside （BrdU）/DCX in hippocampal dentate gyrus， and the protein expression of ZO-1， FRα， RFC， and PCFT in choroid plexus tissues； ELISA technique was used to detect plasma， cerebrospinal fluid， 5-methyltetrahydrofolate （5-MTHF） in hippocampal tissues； Pearson correlation analysis was used to correlate the 5-MTHF content in cerebrospinal fluid and hippocampal tissues and the expression of nestin， DCX， and NeuN proteins in hippocampal tissues of rats in youth depression group and LOD group. ResultsCompared with normal group， rats in youth depression group and LOD group showed reduced sugar water preference， reduced total distance travelled in the absent field， reduced number of times through the grid， prolonged forced swimming immobilisation， reduced hippocampal NeuN， nestin and DCX protein expression， reduced number of Ki-67/nestin double-positive cells in hippocampal dentate gyrus， reduced number of BrdU/DCX double-positive cells in hippocampal dentate gyrus， and reduced expression of ZO-1 and FRα proteins and fluorescence intensity （P＜0.05 or P＜0.01）； the correct rate of T-maze on days 3 and 4 in the rats of youth depression group and on days 2 to 4 in the rats of LOD group significantly decreased， and the content of 5-MTHF in the cerebrospinal fluid and hippocampal tissues of the rats of LOD group significantly decreased as well （P＜0.05 or P＜0.01）. Compared with youth depression group， rats in LOD group showed a decrease in total distance travelled in absenteeism， number of times through the grid， a significant decrease in the correct rate of the T-maze on day 1-4， a decrease in NeuN， nestin， DCX protein expression of hippocampal tissue and the number of Ki-67/nestin double-positive cells， BrdU/DCX double-positive cells of hippocampal dentate gyrus （P＜0.05 or P＜0.01）. Compared with LOD group， rats in Erxian Decoction group had elevated sugar-water preference and total distance travelled in absenteeism and number of times through the grid， shorter forced swimming immobility time， significantly higher correct rate of the T-maze on day 3-4， elevated expression of NeuN， nestin， and DCX proteins in hippocampal tissues， increased number of Ki-67/nestin double-positive cells and BrdU/DCX double-positive cells in hippocampal dentate gyrus， and increased 5-MTHF content in cerebrospinal fluid and hippocampal， and ZO-1， FRα， RFC， PCFT protein expression and fluorescence intensity increased in choroid plexus （P＜0.05 or P＜0.01）. Correlation analysis showed that there was a positive correlation between 5-MTHF content in cerebrospinal fluid （r = 0.466）， hippocampal tissue （r = 0.522） and nestin expression in hippocampal tissue （P＜0.05）. ConclusionErxian Decoction could improve depressive-like behaviour and cognitive impairment in LOD model rats， and its mechanism may promote hippocampal neurogenesis by alleviating structural damage to the choroid plexus of the brain tissue， and improving impaired choroid plexus folate transport.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Taking " harmony of body and spirit" as the theoretical core in Huangdi Neijing and the functional nature and executive structure of the five emotions system as clues, this paper explores and analyzes the relevant theories of the five emotions system in ancient Chinese medicine literature. It is found that the five emotions system is a highly ordered and integrated collection of five functional states. It often resides in the five zang viscera, it operates between the meridians and the xuanfu through the elevation and movement of the qi, and it is the pivotal point for the operation of the qi and blood of the organism, the interactive conduction of information, and the unity of form, emotion, and qi. Therefore, this paper starts from the point of view of system science. It is proposed that the primordial spirit exercises control over the five emotions and the five emotions provide nutrition to the primordial spirit, and that the two are not " islands of information" but have a dynamic and hierarchical internal connection. The executive structure of the five emotions system, namely, the meridians, the xuanfu, and the five zang viscera, is the pivot, and it is recognized that the operation of the five emotions system is a process with self-organizing characteristics and orderly and eternal motion. We think of the qi, blood, ying, and essence as the basis of occurrence, the meridian as the execution channel, and the xuanfu as the place for the spiritual mechanism to enter and exit; the five zang viscera serve as a dwelling place, and ministerial fire serves as the source of energy. This paper serves as reference for future research related to the executive structure of the five emotions system of traditional Chinese medicine.

A new definition of metabolic dysfunction-associated fatty liver disease (MAFLD) has recently been proposed. We aim to examine the associations of MAFLD, particularly its discordance from non-alcoholic fatty liver disease (NAFLD), with the progression of elevated brachial-ankle pulse wave velocity (baPWV) and albuminuria in a community-based study sample in Shanghai, China. After 4.3 years of follow-up, 778 participants developed elevated baPWV and 499 developed albuminuria. In comparison with the non-MAFLD group, the multivariable adjusted odds ratio (OR) of MAFLD group for new-onset elevated baPWV was 1.25 (95% confidence interval (CI) 1.01-1.55) and 1.35 (95% CI 1.07-1.70) for albuminuria. Participants without NAFLD but diagnosed according to MAFLD definition were associated with higher risk of incident albuminuria (OR 1.77; 95% CI 1.07-2.94). Patients with MAFLD with high value of hepamet fibrosis score or poor-controlled diabetes had higher risk of elevated baPWV or albuminuria. In conclusion, MAFLD was associated with new-onset elevated baPWV and albuminuria independently of body mass index, waist circumference, and hip circumference. Individuals without NAFLD but diagnosed as MAFLD had high risk of albuminuria, supporting that MAFLD criteria would be practical for the evaluation of long-term risk of subclinical atherosclerosis among fatty liver patients.

Objective:To Investigate comprehensive predictive ability of first-trimester complete blood count combined with maternal characteristics for gestational diabetes mellitus (GDM).Methods:From May 2015 to July 2018, 1 412 pregnant women were retrospectively screened at the Fifth People′s Hospital of Shanghai, Fudan University. We recruited 258 women who developed GDM and 1 154 women who had normal glucose level during pregnancy. At the first visit, clinical data and complete blood count result were obtained. GDM prediction models were established through logistic regression analysis of GDM related risk factors and the prediction abilities of each model were compared.Results:Logistic regression analyses identified age, pre-pregnancy body mass index, previous GDM history, family history of diabetes mellitus, the neutrophil-to-lymphocyte ratio, leukocyte, neutrophil, and monocyte counts were significantly independent predictors of GDM. In the entire cohort, the predictive ability of neutrophil and monocyte counts together with maternal basal characteristics model for the development of GDM [areas under the receiver operating characteristic curve (AUC-ROC)=0.809, integrated discrimination improvement (IDI)=0.056, P=0.001] was the best among various models (basal characteristics model, AUC-ROC=0.753; Monocyte count+ basal characteristics model, AUC-ROC=0.764; neutrophil count + basal characteristics model, AUC-ROC=0.775). Similar results obtained by the same way in all pregnant women without previous GDM history. Conclusion:It could improve the prediction of GDM with model incorporated maternal characteristics and first-trimester neutrophil and monocyte counts.
