Objective:
To investigate the effect of Guangdong Shenqu (GSQ) on intestinal flora structure in mice with food stagnation through 16S rDNA sequencing.
Methods:
Mice were randomly assigned to control, model, GSQ low-dose (GSQL), GSQ medium-dose (GSQM), GSQ high-dose (GSQH), and lacidophilin tablets (LAB) groups, with each group containing 10 mice. A food stagnation and internal heat mouse model was established through intragastric administration of a mixture of beeswax and olive oil (1:15). The control group was administered normal saline, and the model group was administered beeswax and olive oil to maintain a state. The GSQL (2 g/kg), GSQM (4 g/kg), GSQH (8 g/kg), and LAB groups (0.625 g/kg) were administered corresponding drugs for 5 d. After administration, 16S rDNA sequencing was performed to assess gut microbiota in mouse fecal samples.
Results:
The model group exhibited significant intestinal flora changes. Following GSQ administration, the abundance and diversity index of the intestinal flora increased significantly, the number of bacterial species was regulated, and α and β diversity were improved. GSQ administration increased the abundance of probiotics, including Clostridia, Lachnospirales, and Lactobacillus, whereas the abundance of conditional pathogenic bacteria, such as Allobaculum, Erysipelotrichaceae, and Bacteroides decreased. Functional prediction analysis indicated that the pathogenesis of food stagnation and GSQ intervention were primarily associated with carbohydrate, lipid, and amino acid metabolism, among other metabolic pathways.
Conclusion
The digestive mechanism of GSQ may be attributed to its role in restoring diversity and abundance within the intestinal flora, thereby improving the composition and structure of the intestinal flora in mice and subsequently influencing the regulation of metabolic pathways.

Objective:To explore the pathogenesis of flunarizine-induced parkinsonism from gut-brain axis perspective.Methods:Thirty male C57BL/6 mice were randomly divided into control group and flunarizine group ( n=15). Mice in the control group were given 0.1 mL 50% polyethylene glycol 400+50% saline by gavage once/d for 2 weeks, while mice in the flunarizine group were given 6 mg/mL flunarizine+50% polyethylene glycol 400+50% saline by gavage at a daily dose of 30 mg/kg for 2 weeks. Body mass was recorded 1, 3, 5, 7, 10 and 14 d after drug administration, and motor function was assessed by rotarod test 14 d after drug administration; 16s RNA sequencing was performed in the feces to observe the intestinal flora; intestinal transit function was detected by Evans blue by gavage; and then, the mice were sacrificed and homogenate or frozen sections (brain and intestinal tissues) were prepared; dopamine-ergic neuron expression was detected by Western blotting; RT-qPCR was applied to detect the expressions of inflammatory factors in the substantia nigra, and immunofluorescent staining was used to detect the expressions of ZO-1 and Claudin-5 in the intestinal epithelial tissues. Results:Compared with the control group, the flunarizine group had lower body mass ratio 1, 3, 5, 7, 10 and 14 d after drug administration (ratio to body mass before drug administration). Compared with the control group, the flunarizine group had significantly shortened residence time in rod rotating and lower rotational speed when falling ( P<0.05). Compared with the control group, the flunarizine group had decreased tyrosine hydroxylase protein in the substantia nigra without significant difference ( P>0.05). Compared with the control group, the flunarizine group had significantly increased interleukin-6 and tumor necrosis factor-α in the substantia nigra (1.00±0.00 vs. 2.79±0.83; 1.00±0.00 vs. 3.39±1.37), significantly lower intestinal Evans blue propulsion rate (80.67%±4.51% vs. 50.67%±6.03%), and statistically decreased ZO-1 and Claudin-5 expressions in the colonic epithelial tissues (27.01±1.41 vs. 16.32±2.83; 37.00±2.80 vs. 24.52±2.12, P<0.05). Totally, 576 microorganisms were noted in both control group and flunarizine group, 744 in the control group alone, and 634 in the flunarizine group alone. The intestinal flora β diversity indices in the 2 groups were significantly different based on weighted Unifrac-principle coordinates analysis (PCoA, PCoA1: 39.88%; PCoA2: 30.69%). Compared with the control group, the microbial colony structure of mice in flunarizine group was dominated by phylum thick-walled bacteria and phylum warty microbacteria, and by families Muribaculaceae, Lachnospiraceae and Akkermansiaceae. Compared with the control group, the flunarizine group had significantly decreased relative abundance of Ackermannia spp. and Lactobacillus spp. in the intestinal flora ( P<0.05). Conclusion:Flunarizine may contribute to the pathogenesis of DIP by causing structural disturbances in the intestinal flora and inducing neuroinflammation based on the gut-brain axis.

OBJECTIVE:
We aimed to understand the willingness and barriers to the acceptance of tuberculosis (TB) preventive treatment (TPT) among people with latent TB infection (LTBI) in China.
METHODS:
A multicenter cross-sectional study was conducted from May 18, 2023 to December 31, 2023 across 10 counties in China. According to a national technical guide, we included healthcare workers, students, teachers, and others occupations aged 15-65 years as our research participants.
RESULTS:
Overall, 17.0% (183/1,077) of participants accepted TPT. There were statistically significant differences in the acceptance rate of TPT among different sexes, ages, educational levels, and occupations ( P < 0.05). The main barriers to TPT acceptance were misconceptions that it had uncertain effects on prevention (57.8%, 517/894), and concerns about side effects (32.7%, 292/894).
CONCLUSION
An enhanced and comprehensive understanding of LTBI and TPT among people with LTBI is vital to further expand TPT in China. Moreover, targeted policies need to be developed to address barriers faced by different groups of people.

Objective? To investigate the status of follow-up service of discharged patients from ClassⅡ or ClassⅢ comprehensive hospitals in China. Methods? In June 2018, we selected 150 clinical departments and 228 nurses of 89 ClassⅡ or ClassⅢ comprehensive hospitals in 17 provinces, Municipality and autonomous regions by convenience sampling. The self-designed questionnaire was used to investigate the ways, contents, existing problems and suggestions of follow-up of discharged patients. Results? Follow-up service was mainly carried out by nurses including ward primary nurses and full-time nurses. Besides, the follow-up was mainly with the telephone follow-up, and its content tended to disease health education and consultation. The main existing problems of discharged patients in follow-up service were "follow-up form was too simple and lacking specialty characteristics", "follow-up way was single and follow-up effects were unsatisfactory", "human resources limits and lack of special follow-up staff", "follow-up effects lacking aggregate and analysis" and"nursing problems existing in follow-up lacking following and evaluation". Nurses suggested that "aggregate as well as feedback of follow-up data should be done regularly", "increase follow-up center unified management for discharged patients", "follow-up form should reflect specialty characteristics" and "develop multidisciplinary teamwork". Conclusions? Follow-up service has great significance for improving rehabilitation and quality of life among discharged patients. There are a lot of problems in follow-up service system for discharged patients. We should perfect the common discharged follow-up forms applied to specialties, construct multidisciplinary support platforms and make follow-up management system scientific and informative.

OBJECTIVE:
: To screen genes involved in mitochondrial DNA (mtDNA) damage repair in rats with septic acute kidney injury (SAKI).
METHODS:
: Forty male C57BL/6J mice were randomly divided into SAKI group (=28) and sham operation group (=12). The SAKI mouse model was established by cecal ligation and puncture. Blood and kidney samples were collected at 8, 24, and 48 h after surgery. Serum creatinine and urea nitrogen were measured by a dry biochemical analyzer. Serum inflammatory cytokines were detected by ELISA. Histopathological changes were observed with HE staining. The mtDNA damage repair related genes were screened by RNA sequencing and bioinformatics analysis; the mRNA and protein expression levels of related genes were detected by real-time quantitative RT-PCR and immunohistochemisry, respectively.
RESULTS:
: Symptoms of sepsis were observed in SAKI group, and 16 out of 28 mice were died in the SAKI group; serum TNF-α, IL-6, creatinine and urea nitrogen levels were higher than those in the sham group (<0.05 or <0.01). Histopathological examination in SAKI group showed that renal tubular epithelial cells were swollen, inflammatory cells infiltrated, and a large number of cell vacuoles were seen, suggesting successful modeling. Mitochondrial DNA damage repair related genes and were screened out. The expression of these genes was detected by real-time RT-PCR, and the results were consistent with RNA sequencing trends. Immunohistochemical staining showed that Gadd45α was mainly expressed in the nucleus of renal tubular epithelial cells, and the positive rate of Gadd45α in SAKI group was higher than that in the sham operation group (<0.05).
CONCLUSIONS
: and genes are involved in mtDNA damage repair in rats with SAKI, indicating that these genes may be used as new targets for prevention and treatment of SAKI.

Objective To investigate the incidence and related factors of postoperative hemorrhage, so as to provide data support for preventing its occurrence and developing reasonable risk assessment tools. Methods The retrospective analysis of clinical data of 50 patients with postoperative hemorrhage after surgical operation in a 3A hospital in Shanghai from January to December 2016 was conducted. A 1:2 matching case-control study was conducted to explore the risk factors of postoperative bleeding in surgical patients by univariate and multivariate regression analysis.Results The total number of surgical operations (excluding obstetrics and gynecology, five senses) was 18942. Postoperative hemorrhage occurred in 50 cases, including 6 deaths. The incidence of postoperative hemorrhage was 0.26% and the mortality rate was 12%. The incidence of postoperative bleeding in the top four departments were gastrointestinal surgery (13 cases), hepatobiliary and pancreatic surgery (11 cases), cardiac surgery (10 cases), neurosurgery (9 cases). The statistical analysis of binary Logistic in the case group and the control group showed that postoperative albumin<35g/L, postoperative AST abnormality, postoperative ALT abnormality, postoperative hypertension were independent risk factors of postoperative bleeding.Conclusions The incidence of postoperative bleeding in this hospital is relativelylow, but the mortality is relatively high. Medical staff should pay more attention to the patients undergoing gastrointestinal, liver, pancreas, heart and brain surgery. It is also necessary to pay more attention to the blood pressure, albumin and liver function of the patients after operation,and establish the evaluation of prevention of hemorrhage, which has a certain early warning effect on the prevention of postoperative hemorrhage.

Chronic high-salt diet-associated renal injury is a key risk factor for the development of hypertension. However, the mechanism by which salt triggers kidney damage is poorly understood. Our study investigated how high salt (HS) intake triggers early renal injury by considering the ‘gut-kidney axis’. We fed mice 2% NaCl in drinking water continuously for 8 weeks to induce early renal injury. We found that the ‘quantitative’ and ‘qualitative’ levels of the intestinal microflora were significantly altered after chronic HS feeding, which indicated the occurrence of enteric dysbiosis. In addition, intestinal immunological gene expression was impaired in mice with HS intake. Gut permeability elevation and enteric bacterial translocation into the kidney were detected after chronic HS feeding. Gut bacteria depletion by non-absorbable antibiotic administration restored HS loading-induced gut leakiness, renal injury and systolic blood pressure elevation. The fecal microbiota from mice fed chronic HS could independently cause gut leakiness and renal injury. Our current work provides a novel insight into the mechanism of HS-induced renal injury by investigating the role of the intestine with enteric bacteria and gut permeability and clearly illustrates that chronic HS loading elicited renal injury and dysfunction that was dependent on the intestine.
