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 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.

Protein O-GlcNAcylation is a post-translational modification that links environmental stimuli with changes in intracellular signal pathways, and its disturbance has been found in neurodegenerative diseases and metabolic disorders. However, its role in the mesolimbic dopamine (DA) system, especially in the ventral tegmental area (VTA), needs to be elucidated. Here, we found that injection of Thiamet G, an O-GlcNAcase (OGA) inhibitor, in the VTA and nucleus accumbens (NAc) of mice, facilitated neuronal O-GlcNAcylation and decreased the operant response to sucrose as well as the latency to fall in rotarod test. Mice with DAergic neuron-specific knockout of O-GlcNAc transferase (OGT) displayed severe metabolic abnormalities and died within 4-8 weeks after birth. Furthermore, mice specifically overexpressing OGT in DAergic neurons in the VTA had learning defects in the operant response to sucrose, and impaired motor learning in the rotarod test. Instead, overexpression of OGT in GABAergic neurons in the VTA had no effect on these behaviors. These results suggest that protein O-GlcNAcylation of DAergic neurons in the VTA plays an important role in regulating the response to natural reward and motor learning in mice.

Objective: The study aims to predict 10-year cardiovascular disease (CVD) risk and explore its association with sleep duration among Chinese urban adults. Methods: We analyzed part of the baseline data of a cohort that recruited adults for health screening by cluster sampling. The simplified Pittsburgh Sleep Quality Index (PSQI) and Framingham 10-year risk score (FRS) were used to measure sleep duration and CVD risk. Demographic characteristics, personal history of chronic diseases, lifestyle factors were collected using a questionnaire. Height, weight, total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C) were also measured. Multiple logistic regression models were performed to explore the association of sleep duration with the predicted CVD risk. Results: We included 31, 135 participants (median age 44 years, 53.02% males) free of CVD, cerebral stroke, and not taking lipid-lowering agents. Overall, 14.05%, and 25.55% of participants were at medium and high predicted CVD risk, respectively. Short sleep was independently associated with increased odds of medium to high risk of predicted 10-year CVD among males ( Conclusion A substantial number of adults free of CVD were at high 10-year CVD risk. Short sleep was associated with increased odds of predicted CVD risk.

Objective: As an important food therapy product with traditional Chinese medicine (TCM) applications, donkey-hide gelatin (Asini Corii Colla, ACC) has been used for thousands of years. However, till now few effective strategy had been proposed to distinguish ACC from other animal hide gelatins, especially closely related horse- and mule-hide gelatins, which was an embarrassment of ACC quality control. Methods: Combined mass spectrometry and bioinformatic methods have been applied to identify and verify two ACC-specific peptides (Pep-1 and Pep-2) capable of distinguishing ACC from other closely related animal gelatins with high selectivity. Results: It confirmed that these two peptides could be not only used for distinguishing ACC from highly homologous horse-hide and mule-hide gelatins as well as other animal hide gelatins. Conclusion: The present study provides a simple method for species-specific peptides discovery, which can be used for assessing the quality of animal gelatin products, and ensure they are authenticable and traceable.

From 1999 to 2015, there were 6 186 cases of leukemia deaths in tianjin residents, the males accounted for 58.28% (3 605) and 52.31% (3 236) deaths lived in urban areas; the crude mortality rate of Leukemia increased from 3.47/100 000 to 4.28/100 000 [t=7.09, P<0.001, annual percent change (APC)=1.30%] and the standardized mortality rate decreased from 3.15/100 000 to 3.01/100 000 (t=-2.95, P=0.006, APC=-0.65%). Special attention should be focused on children, the elderly, males and rural residents.

Objective: To investigate the mortality of colorectal cancer and its trend from 1999 to 2015 in Tianjin, China, and to explore the mortality features in different populations in order to provide data for prevention and control strategies of colorectal cancer. Methods: Colorectal cancer mortality data between 1999 and 2015 were collected from Tianjin population - based mortality surveillance system maintained by the Tianjin Centers for Disease Control and Prevention (CDC). Population data of permanent residents were collected from Tianjin Municipal Public Security Bureau. The number of new cases and deaths, incidence [including crude incidence, age-adjusted standardized incidence and 95% confidence interval (95% CI)], and mortality (including crude mortality, age-adjusted standardized mortality and 95% CI) of colorectal cancer were calculated. Standardized incidence and mortality of colorectal cancer were calculated using the Segi′s world standard population, adjusted with age and gender. JoinPoint regression and Cochran-Armitage trend test were used to determine the statistical significance of differences in mortality trend. Results: A total of 31 376 new onset cases and 14 893 death cases of colorectal cancer were observed in Tianjin from 1999 to 2015. Colorectal cancer incidence increased from 1999 to 2015 with a standardized rate from 9.66/100 000 to 15.36/100 000 [annual percent change(APC)=3.48%, Z=23.21, P<0.001]. Colorectal cancer mortality increased from 1999 to 2015 with a standardized rate from 5.18/100 000 to 6.11/100 000 (APC=1.24%, Z=5.69, P<0.001). Both showed an increasing trend. The death proportion of colon cancer increased (39.67% in 1999 and 50.33% in 2015), while the death proportion of rectal caner decreased (60.33% in 1999 and 48.57% in 2015). The median age of colorectal cancer onset fluctuated steadily around 66 years old (APC=0.16, T=1.75, P=0.100); the median age of death increased from 69 to 73 years old (APC=0.43, T=8.81, P<0.001). From 1999 to 2015, the mortality of colorectal cancer showed a downward trend (all P<0.05) in the age groups of <35 and 35-44 years, while an upward trend (all P<0.05) in the age groups of 45-54 years, 55-64 years and ≥ 65 years. Colorectal cancer mortality in males increased with a standardized rate of 5.53/100 000 in 1999 to 7.33/100 000 in 2015(APC=2.29%, Z=7.86, P<0.001), while colorectal cancer mortality in females flatted with a standardized rate of 4.83/100 000 in 1999 to 4.89/100 000 in 2015 (APC=0.10%, Z=-0.30, P=0.752). Colorectal cancer mortality increased with a standardized rate of 6.75/100 000 in 1999 to 7.33/100 000 in 2015 (APC=0.54%, Z=1.98, P=0.048) in urban areas and of 3.18/100 000 in 1999 to 4.38/100 000 in 2015 (APC=2.47, Z=6.46, P<0.001) in rural areas, whose differences were significant. Standardized mortality rate in rural area was lower but the rising velocity was faster as compared to urban area. Conclusions Crude mortality and standardized mortality of colorectal cancer increase from 1999 to 2015 in Tianjin population. The people of elder, male and urban area have higher mortality. The mortality in people of male and rural area presents a faster rising state. Further efforts to reduce colorectal cancer mortality in Tianjin are needed to prevention and control of colorectal cancer.

Objective: This study aims to investigate the menarcheal age of female junior middle school students in Tianjin and associated factors, providing suggestions for further development of adolescence education on physiological and mental health. Methods: A total of 4 127 junior middle school girls in Tianjin area were selected by stratified random sampling method, and investigated by the method of physical examination and questionnaire survey, results were analyzed. Results: There were 1 383 girls reported menarche. Mean age at menarche was(12.68±1.19) years old; One-way ANOVA showed that girls with higher family income, higher parental education had earlier menarcheal age(F=4.97, 9.52, 10.64, P<0.05). It showed that the tendency that obesity group and over-weight group was higher in the rate of menarche than that of normal group and marasmus group(F=4.20, P<0.05). However, different time on watching TV, computer or celephone and sleeping was found to be unrelated with age at menarche(P>0.05). Kruskal Wallis H test showed that girls whose mothers’ AAM was earlier had earlier menarcheal age(H=82.94, P<0.05). According to age, girls were divided into groups of 10-11, 11-12, 12-13 and 13-14 years old. Girls in each age group were divided into the menstruation menarche group and the non-menstruation menarche group. The results showed that the levels of height, weight, BMI, waist circumference, hip circumference, and the skin fold thickness in menstruation group were higher than those in non-menstruation group(t=2.18-10.93, P<0.05). After that, girls of each group were divided into four group：marasmus group, the normal group, the over-weight group and the obesity group according to BMI(χ2=34.66，13.37，11.09，12.60,P<0.05). Conclusion Female junior middle school students’ menarcheal age in Tianjin is related to family income, parents’education, mother’s age at menarche, obesity and physical exercise frequency.
