Fecal microbiota transplantation (FMT) technology originated in China during the Eastern Jin Dynasty and has rapidly developed over the past two decades, becoming a primary method for studying the causal relationship between gut microbiota and the occurrence and progression of diseases. At the same time, the therapeutic effects of FMT in the field of gastrointestinal diseases have gained widespread recognition and are gradually expanding into other disease areas. The FMT procedure is relatively complex, and there is currently no standardized method; its success is influenced by various factors, including the donor, recipient, processing of the fecal material, and the method of implantation. Given the increasingly recognized relationship between gut microbiota and various diseases, FMT has become a research hotspot in both scientific studies and clinical applications, achieving a series of significant advancements. To help researchers better understand this technology, this paper will outline the development history of FMT, summarize common operational methods in research and clinical settings, review its application progress, and look forward to future development directions.

OBJECTIVE To prepare zeolite imidazole framework (ZIF)-8 nanoparticles (NPs) loaded with temozolomide (TMZ) (abbreviated as TMZ@ZIF-8 NPs) drug delivery system, thus increasing drug enrichment and anti-glioma effects in lesions. METHODS After preparing ZIF-8 NPs using the room temperature solution reaction method, the impregnation method was used to prepare TMZ@ZIF-8 NPs drug delivery system. Characterization was carried out using transmission electron microscopy, laser particle size, and Fourier transform infrared spectroscopy, and dissolution and anti-tumor activity experiments in vitro and in vivo were conducted. RESULTS TMZ@ZIF-8 NPs were successfully prepared with the particle size of (126.23±7.92) nm, drug loading amount of (28.79±1.26)%, and 72 h cumulative dissolution rate of (72.36±3.62)%. The results of in vitro anti-tumor activity experiments showed that the relative cell survival rate of ZIF-8 NPs remained above 90%; the prepared TMZ@ZIF-8 NPs delivery system exhibited superior inhibition, higher uptake capacity, and better promoting apoptosis effects on the growth and proliferation of C6 cells as compared with the free TMZ. The results of in vivo anti-tumor activity experiments showed that ZIF-8 NPs were not enriched in the brain of rats, and the enrichment effect of TMZ in the brain was not significant, while TMZ@ZIF-8 NPs had a significant enrichment effect in the brain. CONCLUSIONS ZIF-8 NPs can effectively load TMZ, and successfully prepared TMZ@ZIF-8 NPs can improve TMZ uptake ability and anti-glioma effect.

Pupil size, as a window into the minds of others, plays a crucial role in social interaction. While previous studies have focused on the influence of non-social factors, such as the physical properties of stimuli, on pupil diameter, recent research has emphasized the significant connection between social information processing and pupil size. In this comprehensive review, we aim to explore how the processing of social stimuli (e.g., face, biological motion) and their emotional characteristics affect pupil size. In essence, pupil size is believed to reflect an individual’s perception of social stimuli. It goes beyond simple physical properties and encompasses the processing of complex social information, including social contexts and interactions. The modulation of pupil size in response to social stimuli is believed to be driven by two key mechanisms: emotional arousal and social attention. When individuals encounter emotionally charged social cues, their pupils tend to dilate, indicating heightened emotional engagement. Similarly, the dilation of pupils when individuals focus on specific social cues suggests an increased allocation of cognitive resources to process relevant social information. Furthermore, the connection between pupil size and social information processing has provided intriguing findings in individuals with autism spectrum disorder (ASD). Known for their significant social deficits, individuals with ASD exhibited abnormal pupillary responses when presented with social stimuli. These findings raise the possibility of utilizing pupillary responses as a potential index for identifying individuals with ASD at a relatively younger age. Moreover, the incorporation of pupillary response measurements in the diagnosis holds great promise in transcending the limitations of the minimum diagnostic age. This can have important implications both in terms of theoretical understanding and practical applications related to the diagnosis and intervention of ASD.

Objective:To investigate the influencing of preoperative total bilirubin (TBil) on perioperative complications of hepatolithiasis receiving liver resection.Methods:The retrospective cohort study was conducted. The clinical data of 300 patients with hepatolithiasis who were admitted to 2 medical centers from January 2010 to January 2022 were collected. There were 115 males and 185 females, aged (54±13)years. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for comparison between groups. Measurement data with skewed distribution were represented as M( Q1, Q3), and the Mann-Whitney U test was used for comparison between groups. Count data were expressed as absolute numbers, and the chi-square test was used for comparison between groups. Variables with P<0.10 in the univariate analysis were included into the multivariate analysis. Univariate analysis was conducted using the Logistic regression model,and multivariate analysis was conducted using the Logistic stepwise regression model with backward Wald method. Continuous variables were converted into categorical variables based on commonly reported cutoff values when conducting Logistic regression analysis. Results:(1) Comparison of clinical data of patients with different preoperative TBil. Of 300 patients with hepatolithiasis, there were 252 cases with low level of preoperative TBil as 14.4(11.1,19.7)μmol/L, and there were 48 cases with high level of preoperative TBil as 44.0(31.3,59.8)μmol/L. Of the pati-ents with low level of preoperative TBil, neutrophils percentage was 62%±10%, cases with intra-operative blood transfusion was 29, and cases undergoing anatomical liver resection was 166. Of the patients with high level of preoperative TBil, neutrophils percentage was 70%±11%, cases with intraoperative blood transfusion was 22, and cases undergoing anatomical liver resection was 15. There were significant differences in cases classified as>grade 2 of ASA classification, neutrophils percentage, cases with intraoperative blood transfusion and cases undergoing anatomical liver resection between patients with low and high level of preoperative TBil ( t=5.182, χ2=33.669, 18.775, P<0.05). (2) Comparison of perioperative complications of patients with different preoperative TBil. Of the 252 patients with low level of TBil, there were 151 cases with complications including 35 cases of serious complications, there was 1 case with postoperative liver failure, the duration of postoperative hospital stay was 13.0(10.0,16.0)days. Of the 48 patients with high level of TBil, there were 32 cases with complications including 17 cases of serious complications, there were 6 cases with postoperative liver failure, the duration of postoperative hospital stay was 14.0(10.0,18.8)days. There were significant differences in cases with serious complications and cases with postoperative liver failure between patients with low and high level of preoperative TBil ( χ2=13.041, 20.879, P<0.05). (3) Analysis of factors influencing postoperative serious complications in patients undergoing liver resection. Results of multivariate analysis showed that age, body mass index (BMI), preoperative TBil and volume of intraoperative blood loss were independent factors influencing postoperative serious complications in patients undergoing liver resection for hepatolithiasis ( odds ratio=3.852, 2.358, 2.935, 5.135, 95% confidence interval as 1.478?9.979, 1.110?5.009, 1.398?6.158, 2.088?12.626, P<0.05). Conclusions:Patients with high level of preoperative TBil have a significantly increased risk of postoperative serious complications and liver failure who receive liver resection for hepatolithiasis. Age, preoperative BMI, TBil and volume of intraoperative blood loss are independent factors influencing postoperative serious complications in patients undergoing liver resection for hepatolithiasis.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Cortical interneurons can be categorized into distinct populations based on multiple modalities, including molecular signatures and morpho-electrical (M/E) properties. Recently, many transcriptomic signatures based on single-cell RNA-seq have been identified in cortical interneurons. However, whether different interneuron populations defined by transcriptomic signature expressions correspond to distinct M/E subtypes is still unknown. Here, we applied the Patch-PCR approach to simultaneously obtain the M/E properties and messenger RNA (mRNA) expression of >600 interneurons in layer V of the mouse somatosensory cortex (S1). Subsequently, we identified 11 M/E subtypes, 9 neurochemical cell populations (NCs), and 20 transcriptomic cell populations (TCs) in this cortical lamina. Further analysis revealed that cells in many NCs and TCs comprised several M/E types and were difficult to clearly distinguish morpho-electrically. A similar analysis of layer V interneurons of mouse primary visual cortex (V1) and motor cortex (M1) gave results largely comparable to S1. Comparison between S1, V1, and M1 suggested that, compared to V1, S1 interneurons were morpho-electrically more similar to M1. Our study reveals the presence of substantial M/E variations in cortical interneuron populations defined by molecular expression.

Objective: To investigate whether the co-presence of carotid plaques and low ankle-brachial index (ABI) might increase the risks of ischemic cardiovascular and cerebrovascular event in elderly population. Methods: It was a prospective study. Participants from the elderly cohort of the Kailuan Study, who completed a carotid sonography and ABI examination, were included in this study. Participants underwent physical examinations between 2010 and 2011 and were divided into 3 groups: no carotid plaque and ABI>0.9 group (n=526), carotid plaque and ABI>0.9 group (n=1 067), and carotid plaques and ABI≤0.9 group (n=49). Follow up ended on the 31 December 2016. The incidence of ischemic cardiovascular and cerebrovascular event was compared between the 3 groups, the relationship between carotid plaque and low ABI with ischemic cardiovascular and cerebrovascular event was analyzed. Results: A total of 1 642 participants were included (age, (67.1±6.4) years). There were 1 028 males (62.6%) and 1 028 females(37.4%). The average follow-up time was 5.41 years, the incidence of ischemic cardiovascular and cerebrovascular event in the 3 group was 2.1%(11/526), 5.5%(59/1 067), and 12.2%(6/49),respectively; the incidence of myocardial infarction in the 3 group was 0.2%(1/526), 1.6%(17/1 067), 10.2%(5/49), respectively; the incidence of cerebral infarction in the 3 group was 1.9%(10/526), 3.9%(42/1 067) and 2.0%(1/49), respectively. Multivariate Cox risk proportional regression analysis showed that compared with the group without carotid plaque and ABI>0.9, the HR values (95%CI) of ischemic cardiovascular and cerebrovascular event in the group with carotid plaque and ABI>0.9, carotid plaques and ABI≤0.9 group were 3.52 (1.49-8.35), 7.16(2.11-24.26) respectively, after adjusting for sex,age,systolic blood pressure,fast blood glucose,body mass index,total cholesterol,smoke,alcohol consumption and lipid-lowering medication and antihypertensive medication. Conclusions: Co-presence of carotid plaques and low ankle-brachial index may further increase the risk of ischemic cardiovascular and cerebrovascular event among elderly population in this cohort.

In December 2019, an outbreak of viral pneumonia began in Wuhan, Hubei Province, which caused the spread of infectious pneumonia to a certain extent in China and neighboring countries and regions, and triggered the epidemic crisis. The coronavirus disease 2019(COVID-19) is an acute respiratory infectious disease listed as a B infectious disease, which is managed according to standards for A infectious disease. Traditional Chinese medicine and integrated traditional Chinese and Western medicine have played an active role in the prevention and control of this epidemic. China's ethnomedicine has recognized infectious diseases since ancient times, and formed a medical system including theory, therapies, formula and herbal medicines for such diseases. Since the outbreak of the COVID-19 epidemic, Tibet Autonomous Region, Qinghai Province, Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region and Chuxiong Autonomous Prefecture of Yunnan, Qiandongnan Autonomous Prefecture of Guizhou have issued the prevention and control programs for COVID-19 using Tibetan, Mongolian, Uygur, Yi and Miao medicines. These programs reflect the wisdom of ethnomedicine in preventing and treating diseases, which have successfully extracted prescriptions and preventive measures for the outbreak of the epidemic from their own medical theories and traditional experiences. In this paper, we summarized and explained the prescriptions and medicinal materials of ethnomedicine in these programs, and the origin of Tibetan medicine prescriptions and Mongolian medicine prescriptions in ancient books were studied. These become the common characteristics of medical prevention and treatment programs for ethnomedicine to formulate therapeutic programs under the guidance of traditional medicine theories, recommend prescriptions and prevention and treatment methods with characteristics of ethnomedicine, and focus on the conve-nience and standardization. However, strengthening the support of science and technology and the popularization to the public, and improving the participation of ethnomedicine in national public health services and the capacity-building to deal with sudden and critical diseases are key contents in the development of ethnomedicine in the future.

Risk prediction models including the Prostate Health Index (phi) for prostate cancer have been well established and evaluated in the Western population. The aim of this study is to build phi-based risk calculators in a prostate biopsy population and evaluate their performance in predicting prostate cancer (PCa) and high-grade PCa (Gleason score ≥7) in the Chinese population. We developed risk calculators based on 635 men who underwent initial prostate biopsy. Then, we validated the performance of prostate-specific antigen (PSA), phi, and the risk calculators in an additional observational cohort of 1045 men. We observed that the phi-based risk calculators (risk calculators 2 and 4) outperformed the PSA-based risk calculator for predicting PCa and high-grade PCa in the training cohort. In the validation study, the area under the receiver operating characteristic curve (AUC) for risk calculators 2 and 4 reached 0.91 and 0.92, respectively, for predicting PCa and high-grade PCa, respectively; the AUC values were better than those for risk calculator 1 (PSA-based model with an AUC of 0.81 and 0.82, respectively) (all P < 0.001). Such superiority was also observed in the stratified population with PSA ranging from 2.0 ng ml-1to 10.0 ng ml-1. Decision curves confirmed that a considerable proportion of unnecessary biopsies could be avoided while applying phi-based risk calculators. In this study, we showed that, compared to risk calculators without phi, phi-based risk calculators exhibited superior discrimination and calibration for PCa in the Chinese biopsy population. Applying these risk calculators also considerably reduced the number of unnecessary biopsies for PCa.
