Objective To analyze the occurrence characteristics of adverse events following immunization (AEFI) of 23-valent pneumococcal polysaccharide vaccine (PPSV-23) in Hebei Province and to evaluate the safety of the vaccine. Methods AEFI cases related to vaccination of PPSV-23 in Hebei Province from January 1, 2020 to December 31, 2022 were collected through the AEFI surveillance module of Chinese Center for Disease Control and Prevention Information System. The incidence of reported AEFI cases were then analyzed and compared. Results The reported incidence rate of AEFI of PPSV-23 was 56.12 /100,000 doses, and the incidence rate of adverse reactions was 55.50 /100 000 doses. The incidence rate of common adverse reactions was 53.94/100 000 doses, and the incidence rate of rare adverse reactions was 1.56/100 000 doses. Most of the reported AEFI cases caused by PPSV-23 were common adverse reactions, which occurred mainly within one day after vaccination, and the overall regression was positive. Conclusion The 23-valent pneumococcal polysaccharide vaccine used in Hebei Province is safe，but its safety monitoring still needs to be strengthened.
Résumé
The gene TNFAIP3 acts as a negative regulator of the NF-κB signaling pathway. TNFAIP3 encodes the A20 protein，which exerts a potent anti-inflammatory effect and plays a pivotal role in the regulation of inflammation and immunity. In recent years，TNFAIP3 has garnered significant attention as a susceptibility gene for numerous autoimmune diseases，including but not limited to systemic lupus erythematosus，rheumatoid arthritis，psoriasis. Additionally，high-penetrance heterozygous mutations in TNFAIP3 cause a haploinsufficiency of A20（HA20）. HA20 is a monogenic autoinflammatory disease. But some individuals of HA20 exhibit clinical features of autoimmune diseases，including varying degrees of autoantibody positivity，lupus-like phenotypes，and autoimmune thyroid disease.This article focuses on the single nucleotide polymorphism of TNFAIP3 and related autoimmune diseases，to underscore the crucial role of TNFAIP3 in the pathogenesis of autoimmune diseases，and to provide new research directions and potential drug targets for these conditions.

@#Objective Previous research has indicated a discernible association between gut microbiota and vestibular dysfunction； however，further investigation is required to establish a causal relationship. This study aims to comprehensively study the causal relationship between gut microbiota and vestibular dysfunction and determine the species of related gut microbes. Methods A two-sample Mendelian randomization analysis was performed. The gut microbiome data of 18 340 individuals obtained from the genome-wide association study （GWAS） by the MiBioGen consortium in 2021 were used as the exposure samples. The GWAS data related to vestibular dysfunction were used as the outcome samples. The inverse variance weighting method was employed to analyze the gut microbiome data. The results were assessed based on the odds ratio（OR）as the effect index with 95% confidence interval（CI）. The stability and reliability of the findings were assessed using the leave-one-out，heterogeneity，horizontal pleiotropy，and false discovery rate approaches. Results The results indicated a significant association between an elevated abundance of Bifidobacterium and a decreased risk of vestibular dysfunction. Furthermore，the leave-one-out method confirmed the stability of the results and the absence of instrumental variables exerting substantial influence on the findings. The causal relationship was negative. The influence of heterogeneity and horizontal pleiotropy on the causal effect could be eliminated. Conclusion Bifidobacterium may affect vestibular dysfunction by influencing 5-HT through the “gut-brain axis”，but this result still needs further verification.
Résumé
@#Persistent postural-perceptual dizziness （PPPD） is a common clinical chronic dizziness disease，with persistent dizziness，instability，or non-rotational vertigo as the main symptom. It may be aggravated by postural changes，active/passive movements，and exposure to complex visual environments. At present，it is believed that the occurrence of PPPD may be related to the failure of postural control readaptation and abnormal cortical multisensory integration，but the specific pathophysiological mechanism is not clear. In recent years，with the continuous application of neuroimaging technology in the field of vertigo diseases，it has been found that in patients with PPPD，the brain structure，function，and connectivity related to vestibular multisensory and spatial orientation are decreased，while the function and connectivity related to visual processing are enhanced. At the same time，various psychiatric factors （such as anxiety，depression，and neuroticism） as well as triggers may be involved in regulating the brain structure of people with PPPD，which helps explain the differences in outcomes between studies. The above neuroimaging findings are helpful for the early diagnosis and treatment of PPPD. Therefore，this paper reviews the neuroimaging studies of PPPD to provide a reference for explaining the pathophysiological mechanism of PPPD.

@#Objective To develop and validate a nomogram model to predict the risk of post-stroke cognitive impairment(PSCI) in patients with mild acute ischemic stroke(AIS). Methods We included 315 patients with mild AIS(181 in the PSCI group and 134 in the non-PSCI group) who were admitted to the Department of Neurology of the First Hospital of Jilin University from April 2019 to January 2021.Fifteen potential predictors associated with vascular cognitive impairment(VCI) were selected. The selection of predictors for the PSCI nomogram model was optimized by least absolute shrinkage and selection operator regression. The number of predictors with high effects on PSCI was finally reduced to 10.Based on the 10 predictors,we performed multivariable logistic regression analysis and construct the nomogram model. The accuracy,discriminatory ability,and clinical utility of the prediction model were assessed by using the C-index,calibration curve,and decision curve analysis(DCA). The Bootstrapping validation method was used for internal validation of the model. Results The nomogram model for PSCI risk prediction included five predictors:age,sex,education level,past stroke history,and the diameter of maximum transverse section(DMTS). The C-index of the nomogram model was 0.708(95% confidence interval:0.651-0.765),with good discriminatory ability. The C-index by internal validation was 0.682.The calibration curves showed good consistency. DCA indicated a higher net benefit by using this nomogram model for predicting the risk of PSCI when the probability threshold of PSCI was greater than 27%. Conclusion This PSCI risk nomogram model is based on age,sex,education level,past stroke history,and DMTS,which can help clinicians predict the risk of PSCI for patients with mild AIS. It is worthy of clinical promotion and application.

AIM: To analyze the clinical effect of 577nm subthreshold micropulse laser(SML)photocoagulation combined with intravitreal injection of Conbercept in the treatment of diabetic macular edema(DME)after vitrectomy in patients with proliferative diabetic retinopathy(PDR).METHODS:A retrospective analysis was performed on 29 cases(30 eyes)of PDR patients who had DME after vitrectomy in our hospital from January 2019 to June 2021. They were divided into two groups according to different treatment methods: 14 cases(14 eyes)in the single injection group received intravitreal injection of Conbercept, and 15 cases(16 eyes)in the combined treatment group received 577nm SML photocoagulation in the macular area combined with intravitreal injection of Conbercept. The changes in best corrected visual acuity(BCVA)and central macular thickness(CMT)before and at 6 and 12mo after treatment, as well as the changes of multifocal electroretinogram(mfERG)before and at 12mo after treatment were compared between the two groups.RESULTS: The BCVA(LogMAR)of patients in both groups improved and CMT decreased after treatment for 6 and 12mo(all P<0.001). There were no significant differences in BCVA(LogMAR)and CMT before treatment and 6mo, 12mo after treatment between single injection group and combined treatment group(all P>0.05). Compared with the combined treatment group, the amplitude was slightly lower(23.02±3.13 vs. 26.50±3.33 μV/deg2)and the latency time was prolonged(38.75±1.62 vs. 34.21±3.06ms)in single injection group at 12mo(all P≤0.001). The average injection times in single injection group was 8.14±1.46, and 5.05±1.51 in combined treatment group at 12mo after treatment(P<0.05).CONCLUSION: 577nm SML photocoagulation combined with intravitreal injection of conbercept can effectively relieve macular edema, improve BCVA and visual function of macular area and reduce the injection times of conbercept for DME patients.

OBJECTIVES@#Ulcerative colitis (UC) is a type of inflammatory bowel disease (IBD) mainly characterized by inflammation, ulceration and erosion of colonic mucosa and submucosa. Transient receptor potential vanilloid 1 (TRPV1) is an important mediator of visceral pain and inflammatory bowel disease. This study aims to investigate the protective effect of water soluble propolis (WSP) on UC colon inflammatory tissue and the role of TRPV1.@*METHODS@#Male SD rats were randomly divided into 6 groups (n=8): a normal control (NC) group, an ulcerative colitis model (UC) group, a low-WSP (L-WSP) group, a medium-WSP (M-WSP) group, a high-WSP (H-WSP) group, and a salazosulfapyridine (SASP) group. The rats in the NC group drank water freely, and the other groups drank 4% dextran sulfate sodium (DSS) solution freely for 7 d to replicate the ulcerative colitis model. Based on the successful replication of the UC, the L-WSP, M-WSP, and H-WSP groups were given 50, 100, and 200 mg/kg of water-soluble propolis by gavage for 7 d, and the SASP group was given 100 mg/kg of sulfasalazine by gavage for 7 d. The body weight of rats in each group was measured at the same time every day, the fecal traits and occult blood were observed to record the disease activity index (DAI). After intragastric administration, the animals were sacrificed after fasted 24 h. Serum and colonic tissue were collected, and the changes of MDA, IL-6 and TNF-α were detected. The pathological changes of colon tissues were observed by HE staining, and the expression of TRPV1 in colon tissues was observed by Western blotting, immunohistochemistry, and immunofluorescence.@*RESULTS@#The animals in each group that drank DSS freely showed symptoms such as weight loss, decreased appetite, depressed state, and hematochezia, indicating that the model was successfully established. Compared with the NC group, DAI scores of other groups were increased (all P<0.05). MDA, IL-6, TNF-α in serum and colon tissues of the UC group were increased compared with the NC group (all P<0.01), and they were decreased after WSP and SASP treatment (all P<0.01). The results of showed that the colon tissue structure was obviously broken and inflammatory infiltration in the UC group, while the H-WSP group and the SASP group significantly improved the colon tissue and alleviated inflammatory infiltration. The expression of TRPV1 in colon tissues in the UC group was increased compared with the NC group (all P<0.01), and it was decreased after WSP and SASP treatment.@*CONCLUSIONS@#WSP can alleviate the inflammatory state of ulcerative colitis induced by DSS, which might be related to the inhibition of inflammatory factors release, and down-regulation or desensitization of TRPV1.

OBJECTIVE@#To explore the relationship between occurrence of acute graft-versus-host disease (aGVHD) and various immune cell composition in patients with acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).@*METHODS@#The clinical data of 104 patients with AML undergoing allo-HSCT in our hospital were retrospectively analyzed, and the hematopoietic reconstitution and occurrence of GVHD were analyzed. Flow cytometry was used to detect the proportion of various types of immune cells in the grafts, the number of graft composition in patients with different degrees of aGVHD was calculated and compared, and to analyze the correlation between the severity of aGVHD in AML patients after allo-HSCT and the immune cell components in the graft.@*RESULTS@#There was no significant difference in the time of hematopoietic reconstitution between the high number group of total number of nucleated cells (TNC) and the low number group, while the time of neutrophil and platelet reconstruction in the high number of CD34 group was significantly faster than that in the low number of CD34 group (P＜0.05), and the total hospital stay also tends to be shorten. Compared with patients in 0-Ι aGVHD group, both HLA-matched and HLA-haploidentical transplantation, the infusion amounts of CD3+ cells, CD3+CD4+ cells, CD3+CD8+ cells, NK cells and CD14+ monocytes were higher in patients of Ⅱ-Ⅳ aGVHD group， but the difference was not statistically significant (P>0.05); In addition, in patients with HLA-haploidentical transplantation, the number of CD4+CD25+ cells in Ⅱ-Ⅳ aGVHD group was significantly lower than that in 0-Ι aGVHD group (P<0.05), and the same trend was also observed in HLA-matched transplanted patients, but the difference was not significant (P=0.078).@*CONCLUSION@#High number of CD34+ cells in the graft is beneficial to hematopoietic reconstitution in AML patients. To a certain degree, high number of CD3+ cells, CD3+CD4+ cells, CD3+CD8+ cells, NK cells and CD14+ cells tend to increase the occurrence of aGVHD, but high number of CD4+CD25+ regulatory T cells is beneficial to reduce the incidence of aGVHD in AML patients.

OBJECTIVE@#To establish a surveillance and early warning index system for schistosomiasis transmission risk along the middle and lower reaches of the Yangtze River basin, so as to provide insights into creation of a sensitive and highly efficient surveillance and early warning system for schistosomiasis.@*METHODS@#National and international publications, documents, laws and regulations pertaining to schistosomiasis control were retrieved with keywords including schistosomiasis, surveillance, early warning and control interventions from 2008 to 2022, and a thematic panel discussion was held to preliminarily construct surveillance and early warning index system for schistosomiasis transmission risk along the middle and lower reaches of the Yangtze River basin. The index system was then comprehensively scored and screened using the Delphi method, and the weight of each index was determined using analytic hierarchy process and the modified proportional allocation method. In addition, the credibility of the Delphi method was evaluated using positive coefficient, authority coefficient, degree of concentration and degree of coordination of experts.@*RESULTS@#Following two rounds of expert consultation, a surveillance and early warning index system for schistosomiasis transmission risk in endemic areas along the middle and lower reaches of the Yangtze River basin was preliminarily constructed, including 3 primary indicators, 9 secondary indicators and 41 tertiary indicators. The normalized weights of primary indicators epidemics, natural and social factors and comprehensive control were 0.639 8, 0.145 6 and 0.214 6, respectively, and among all secondary indicators, snail status (0.321 3) and schistosomiasis prevalence (0.318 5) had the highest combined weights, while social factors had the lowest combined weight (0.030 4). Of all tertiary indicators, human egg-positive rate (0.041 9), number of acute schistosomiasis cases (0.041 5), number of stool-positive bovine and sheep (0.041 1), and prevalence of Schistosoma japonicum in free-ranging livestock (0.041 1) had the highest combined weights. During two rounds of consultation, the positive coefficient of experts was both 100%, and the authority coefficient was both 0.9 and greater, while the coordination coefficients were 0.338 to 0.441 and 0.426 to 0.565 (χ2 = 22.875 to 216.524, both P values < 0.05).@*CONCLUSIONS@#The established surveillance and early warning index system for schistosomiasis transmission risk along the middle and lower reaches of the Yangtze River basin is of great scientific values and authority, which may provide insights into construction of the sensitive and highly efficient surveillance and early warning system for schistosomiasis in the context of low prevalence and low intensity of infection in China.

All the data showed a trend of increase with the teaching reform process.Conclusion:Strengthening the teaching reform of the combination of basic medicine and clinical medicine during the learning stage of basic medicine could improve students' learning interest and attention to the basic medical knowledge, strengthen the understanding of the relevance of basic medicine to clinical medicine, and play a positive role in the cultivation of medical students' post competency and the achievement of the goal of training applied medical talents.
Résumé
Objective:To explore the effect of mastoscopic axillary lymph node dissection (MALND) and conventional axillary lymph node dissection (CALND) in breast conserving surgery for breast cancer.Methods:This study adopts a case-control study. We selected 40 female breast cancer patients who underwent MALND in Tangshan People's Hospital from July 2016 to August 2019 (observation group), and 40 female breast cancer patients who underwent CALND in the same period as the control group. The two groups of patients were operated by the same group of doctors. After tracheal intubation and general anesthesia, the patients underwent breast conserving surgery first. After the intraoperative frozen pathology showed that breast conserving was successful, the control group underwent MALND, and the observation group underwent breast endoscopic axillary lymph node dissection. The levels of blood biochemical indicators, inflammatory factors, stress response indicators, myocardial injury markers and tumor blood circulation micrometastasis indicators, the number of lymph node dissection, operation time, intraoperative bleeding, postoperative drainage, hospital stay, hospital expenses and other surgical observation indicators, as well as the incidence of postoperative complications were compared between the two groups 3 days after operation. The measurement data with normal distribution was expressed by xˉ± s, and the comparison between the two groups was conducted by independent sample t-test; The counting data was expressed in cases (%), and the χ 2 test or Fisher exact probability method was used for comparison between groups. Results:Three days after operation, the erythrocyte count and hemoglobin level in the observation group were lower than those in the control group ((4.03±0.57)×10 12/L vs (4.33±0.54)×10 12/L, (110.90±24.20) g/L vs (129.70±14.90) g/L), cTnI, creatine kinase and CK-MB levels were higher than those in the control group ((17.4±2.3) μg/L vs (13.1±1.8) μg/L, (178.1±35.4) U/L vs (133.1±45.1) U/L, (10.7±1.6) U/L vs (7.0±1.2) U/L), the operation time was longer than that of the control group ((89.4±15.6) min vs (69.6±13.8) min), the intraoperative bleeding volume and postoperative drainage volume were more than that of the control group ((69.5±6.4) mL vs (33.3±7.7) mL, (334.5±51.1) mL vs (236.8±44.3) mL), but the hospital stay was shorter than that of the control group ((7.1±3.1) d vs (15.5±4.7) d). The cost of hospitalization was lower than that of the control group ((13 689.7±1 204.2) yuan compared with (19 734.5±1 391.5) yuan), and the difference was statistically significant ( t values were 2.16, 3.71, -11.69, -4.68, -11.34, -6.01, -22.87, -9.14, 9.44, 20.78; all P<0.05). There was no statistically significant difference between the two groups in inflammatory factors, stress response indicators, cell adhesion factor levels, number of lymph node dissection and postoperative complications (all P>0.05). Conclusions:Compared with CALND, MALND for breast cancer patients will not cause serious inflammatory reaction and stress reaction, and will not increase the risk of tumor blood micrometastasis and the incidence of complications, but will cause some damage to myocardial cells. Lipolysis and liposuction during MALND can increase intraoperative bleeding volume and postoperative drainage volume, and prolong the operation time while improving the quality of the operation field, However, it has obvious advantages in shortening hospitalization time and reducing hospitalization expenses.
