Objective To analyze the epidemiological characteristics of statutory infectious diseases in Yichang City from 2015 to 2023 and evaluate the effectiveness of non-pharmaceutical interventions (NPIs) in infectious disease prevention and control, and to provide a basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze annual incidence rates. SARIMA and SARIMA intervention models were constructed to predict the incidence rates of infectious diseases. Interrupted time series analysis (ITS) was applied to assess the control effectiveness. Results The average annual incidence rate from 2015 to 2023 was 787.47/100 000, with the top five diseases being influenza, hand-foot-and-mouth disease, hepatitis B, tuberculosis, and diarrheal diseases. The average incidence rate from 2015 to 2019 (654.31/100 000) was significantly higher than that from 2020 to 2022 (489.01/100 000) (χ²= 3 499.6, P < 0.05). The total incidence rate in 2023 (2 396.51/100 000) was significantly higher than the average annual incidence rates from 2015-2019 (χ²= 108 186.1, P < 0.05) and 2020-2022 (χ²= 112 869.4, P < 0.05). SARIMA model results indicated that the actual incidence rate from 2020 to 2022 decreased by 73.49% compared to the predicted rate without intervention, with the highest decline observed in respiratory infectious diseases (79.57%). The SARIMA-intervention model showed a 55.48% relative decrease in the total incidence rate for 2023, with the largest reduction in respiratory infectious diseases (63.28%) and a slight increase in intestinal infectious diseases (5.48%). Conclusion NPIs effectively reduce the incidence of statutory infectious diseases in the short term, especially for acute respiratory and intestinal infectious diseases. However, long-term effectiveness faces challenges, necessitating the development of differentiated prevention and control strategies.

ObjectiveThis study aims to explore the effects of Huangqin Qingre Chubi capsules-containing serum on the expression of CircRNA_0001543/nuclear factor-kappa B （NF-κB） in co-cultured peripheral blood mononuclear cells （PBMCs） and human fibroblast-like synoviocytes （FLSs） from patients with ankylosing spondylitis （AS）. MethodsVenous blood was collected from patients with AS to isolate PBMCs. FLSs were co-cultured with AS patients' PBMCs， and FLSs were harvested after co-culture for subsequent experiments. The normal control group consisted of normal FLSs， while the model group comprised co-cultured AS PBMCs and FLSs to simulate AS pathology. The Huangqin Qingre Chubi capsules group involved adding Huangqin Qingre Chubi capsules-containing serum to the co-cultured cells（6.48 g·kg^-1）. To investigate the effect of HQC-containing serum on the viability of co-cultured cells， and the experiment was divided into the following groups based on the dilution concentration： blank group， 10% HQC group， 20% HQC group， and 30% HQC group.To study the influence of the optimal concentration of HQC-containing serum on cytokine and pathway indicators in each group， the experiment was divided into three groups： normal group， model group， and optimal concentration HQC-containing serum group.For the validation of the transfection efficiency of the CircRNA_0001543 interference plasmid， the experiment was divided into the following groups： blank group， si-NC group （with transfection reagent）， si-circ_0001543-1 group （with transfection reagent and interference plasmid No. 1 targeting circ_0001543）， si-circ_0001543-2 group （with transfection reagent and interference plasmid No. 2 targeting circ_0001543）， and si-circ_0001543-3 group （with transfection reagent and interference plasmid No. 3 targeting circ_0001543）.For the validation of the transfection efficiency of the CircRNA_0001543 overexpression plasmid， the experiment was divided into the following groups： blank group， OE-NC group （with transfection reagent）， and OE-circ_0001543 group （with transfection reagent and overexpression plasmid targeting circ_0001543）.To study the effects of CircRNA_0001543 interference/overexpression on cytokine and pathway indicators in each group， the experiment was divided into the following groups： si-NC group， si-CircRNA_0001543 group， OE-NC group， and OE-CircRNA_0001543 group. Enzyme-linked immunosorbent assay （ELISA） was used to detect levels of interleukin-1β （IL-1β）， IL-10， IL-37， and tumor necrosis factor-α （TNF-α）. Real-time quantitative polymerase chain reaction （Real-time PCR） was utilized to measure the expression of CircRNA_0001543， IκBα， and NF-κB p65. ResultsAfter 48 hours， 30% Huangqin Qingre Chubi Capsules-containing serum significantly inhibited the proliferation of co-cultured PBMCs and FLSs， which was determined to be the optimal experimental drug-containing serum concentration. Compared with those in the normal group， the expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α in the model group were significantly increased （P<0.01）， while the expressions of CircRNA_0001543 mRNA， IL-10， and IL-37 were significantly decreased （P<0.01）. Compared with those in the model group， the expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α in the Huangqin Qingre Chubi Capsules-containing serum group were significantly decreased （P<0.05）， and the expressions of CircRNA_0001543 mRNA， IL-10， and IL-37 were significantly increased （P<0.05）， with the most prominent changes in the 30% drug-containing serum group （P<0.01）. Compared with that in the si-NC group， the expression of CircRNA_0001543 was significantly reduced in the si-CircRNA_0001543 group （P<0.01）. Compared with that in the OE-NC group， the expression of CircRNA_0001543 was significantly increased in the OE-CircRNA_0001543 group （P<0.01）， indicating that the si-CircRNA_0001543 and OE-CircRNA_0001543 plasmids were successfully transfected. Based on the optimal drug-containing serum of Huangqin Qingre Chubi Capsules， si-CircRNA_0001543 transfection led to significantly increased expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α and decreased the expressions of IL-10 and IL-37 （P<0.01）. In contrast， OE-CircRNA_0001543 transfection significantly decreased the expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α （P<0.01） and increased the expressions of IL-10 and IL-37 （P<0.01）. ConclusionHuangqin Qingre Chubi capsules-containing serum can improve immune inflammation in AS by increasing the expression of CircRNA_0001543， regulating the NF-κB pathway， suppressing pro-inflammatory cytokines， and enhancing anti-inflammatory cytokine expression.

Objective: To evaluate the effects of a multidisciplinary weight management intervention, so as to provide a reference for the formulation of overweight and obesity intervention measures. Methods: From April to September 2025, overweight and obese residents aged 18-60 years who participated in a weight loss competition at the Health Management Center of Beilun People's Hospital in Ningbo City were selected as study subjects. They were divided into a control group and an intervention group. The control group received conventional weight management, while the intervention group received the multidisciplinary integrated weight management in addition to the conventional weight management, for a total intervention period of 8 weeks. Weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio, fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and blood pressure were collected before and after the intervention through physical examinations and laboratory tests. The generalized estimating equations (GEE) method was employed to analyze the differences in indicators between the two groups before and after the intervention. Results: The control group comprised 241 participants, including 161 females (66.80%), with a mean age of (35.66±7.80) years. The intervention group consisted of 127 participants, including 86 females (67.72%), with a mean age of (36.80±7.05) years. No statistically significant differences were observed between the two groups at baseline in terms of age, gender, weight, BMI, or waist-to-hip ratio (all P>0.05). Results from the GEE analysis indicated significant interactions between group and time for weight, BMI, waist circumference, and hip circumference (all P<0.05) with greater reductions in these parameters observed in the intervention group compared to the control group before and after the intervention. Similarly, significant interactions between group and time were observed for FBG, TG, TC, and LDL-C (all P<0.05), with the intervention group demonstrating larger decreases in these markers compared to the control group. However, no statistically significant interactions between group and time were observed for waist-to-hip ratio, HDL-C, systolic blood pressure, and diastolic blood pressure (all P>0.05). Following the intervention, a weight loss exceeding 10% was achieved by 13 participants (5.39%) in the control group and 62 participants (48.82%) in the intervention group. The proportion of individuals with a weight loss exceeding 10% was significantly higher in the intervention group compared to the control group (P<0.05). Conclusion Compared to conventional weight management, multidisciplinary integrated weight management demonstrated greater efficacy in improving weight-related indicators and blood glucose, blood lipids, and enhancing weight loss outcomes among overweight and obese residents.

OBJECTIVE: To explore effectiveness of intermediate screw assisted reduction and fixation technique in the treatment of Schatzker type Ⅴ and Ⅵ tibial plateau fractures. METHODS: A clinical data of 22 patients with Schatzker type Ⅴ and Ⅵ tibial plateau fractures, who were admitted between June 2022 and December 2023 and met the selection criteria, was retrospectively analyzed. During operation, the intermediate screw assisted reduction and fixation technique was used. There were 14 males and 8 females with an average age of 46.3 years (range, 17-65 years). The fractures were caused by traffic accident in 13 cases, by falls in 5 cases, and by falling from height in 4 cases. According to Schatzker classification criteria, 9 cases were type Ⅴ and 13 cases were type Ⅵ. The interval between injury and operation was 5-12 days (mean, 7.9 days). The operation time, intraoperative fluoroscopy times, and length of hospital stay were recorded. The range of motion of knee joint and Hospital for Special Surgery (HSS) score were recorded at last follow-up. X-ray films were taken to review the fracture healing. Rasmussen score, tibial plateau varus angle (TPVA), and posterior tibial slope (PTS) were estimated before operation, at immediate after operation, and at last follow-up in order to evaluate the fracture reduction effect and postoperative outcome. RESULTS: The operation time was 85-140 minutes (mean, 103.9 minutes). Intraoperative fluoroscopy was performed 7-15 times (mean, 10.1 times). All incisions healed by first intention after operation, and no complication such as nerve or blood vessel injury occurred. The length of hospital stay ranged from 8 to 17 days (mean, 12.4 days). All patients were followed up 10-22 months (mean, 14.8 months). At last follow-up, the range of motion of knee joint was 110°-140° (mean, 125°). HSS score was rated as excellent in 16 cases, good in 5 cases, and fair in 1 case, with an excellent and good rate of 95.5%. X-ray films reexamination showed that all fractures healed with the healing time of 12-17 weeks (mean, 14.8 weeks). No internal fixation failure occurred. Rasmussen score, TPVA, and PTS at immediate after operation and at last follow-up were significantly superior to those before operation ( P<0.05). And there was no significant difference between immediately after operation and last follow-up ( P>0.05). CONCLUSION The treatment of Schatzker type Ⅴ and Ⅵ tibial plateau fractures with intermediate screw assisted reduction and fixation technique is reliable, which can reduce the difficulty of reduction and fixation, improve the efficiency of reduction and fixation, reduce the operation time, achieve satisfactory reduction and fixation effect and postoperative prognosis, and achieve good recovery of knee joint function.

OBJECTIVE: To evaluate the effectiveness of V-shaped stealth decompression technique using ultrasonic bone scalpel in anterior surgery for adjacent two-level cervical spondylosis. METHODS: A clinical data of 41 patients with adjacent two-level cervical spondylosis, who admitted between January 2020 and December 2023 and met the selection criteria, was analyzed retrospectively. Among them, 22 cases were treated with anterior cervical discectomy and fusion (ACDF) assisted by V-shaped stealth decompression technique using ultrasonic bone scalpel (group A) and 19 cases with anterior cervical corpectomy and fusion (ACCF) (group B). There was no significant difference between the two groups in age, gender, disease duration, surgical segment, preoperative Japanese Orthopedic Association (JOA) score, neck dysfunction index (NDI), pain visual analogue scale (VAS) score, and the anteroposterior diameter of the spinal canal in the responsibility space of axial CT ( P>0.05). The operation time, intraoperative blood loss, postoperative drainage volume, hospital stay, complications during follow-up, JOA score, NDI, and VAS score at last follow-up, and the incidences of intervertebral fusion at 3 months after operation, and cage subsidence at last follow-up were compared between the two groups. RESULTS: The operations in the two groups were successfully completed. The operation time, intraoperative blood loss, postoperative drainage volume, and hospital stay in group A were significantly less than those in group B ( P<0.05). Two cases (9.1%) in group A and 4 cases (21.1%) in group B developed complications, with no significant difference in the incidence between the two groups ( P>0.05). All patients in the two groups were followed up 6-12 months (mean, 9.3 months). There was no significant difference in follow-up time between the two groups ( P>0.05). At last follow-up, the JOA score and VAS score in both groups significantly improved when compared with those before operation ( P<0.05). The change values of VAS score and the improvement rate of JOA score in group A were significantly superior to group B ( P<0.05). There was no significant difference in the change values of NDI and JOA score between the two group ( P>0.05). Imaging reexamination showed that the rate of intervertebral fusion at 3 months after operation was significantly higher in group A (81.8%) than in group B (52.6%) ( P<0.05), and all patients obtained bony intervertebral fusion at last follow-up. At last follow-up, 2 cases (9.1%) in group A and 11 cases (57.9%) in group B had cage sinking, and the difference in the incidence was significant ( P<0.05). No loosening or fracture of internal fixators occurred in all patients. CONCLUSION Using ultrasonic bone scalpel can transform single vertebral ACCF into two-segment ACDF in anterior cervical spondylosis surgery. The V-shaped stealth decompression technique is safe and efficient, with the advantages of minimal trauma, fewer postoperative complications, and rapid recovery of patients.

Intestinal aging is central to systemic aging, characterized by a progressive decline in intestinal structure and function. The core mechanisms involve dysregulation of epithelial cell renewal and gut microbiota dysbiosis. In addition to previous results in model organisms like Drosophila melanogaster, recent studies have shown that in mammalian models, aging causes increased intestinal permeability and intestinal-derived systemic inflammation, thereby affecting longevity. Therefore, anti-intestinal aging can be an important strategy for reducing frailty and promoting longevity. There are three key gaps remaining in the study of intestinal aging: (1) overemphasis on aging-related diseases rather than the primary aging mechanisms; (2) lack of specific drugs or treatments to prevent or treat intestinal aging; (3) limited aging-specific dysbiosis research. In this review, the basic structures and renewal mechanisms of intestinal epithelium, and mechanisms and potential therapies for intestinal aging are discussed to advance understanding of the causes, consequences, and treatments of age-related intestinal dysfunction.

Platelet transfusion refractoriness (PTR) is a common issue among patients with hematological diseases and tumors. This article reviews the diagnostic criteria, influencing factors, and recent prevention and management strategies for immune PTR. The diagnostic criteria typically involve post-transfusion platelet increment (PI), platelet recovery rate (PPR), and corrected count increment (CCI). Both immune and non-immune factors can lead to PTR, with immune factors mainly including HLA and HPA antibodies. Prevention and management strategies include the use of leukocyte-reduced platelets, HLA and HPA antigen-matched platelets, intravenous immunoglobulin therapy, and immunosuppressive strategies. Although various strategies have been proposed and applied in clinical practice, the prevention and management of immune PTR remain challenging. Future research needs to explore more effective individualized treatment strategies, while also considering the potential application of emerging technologies such as nanotechnology in the field of transfusion.

Objective:To explore a staged repair procedure for whole foot skin degloving injury and evaluate the clinical outcome.Methods:From August 2020 to March 2023, a retrospective analysis was conducted on 20 patients, 12 males and 8 females, with who had whole foot skin avulsion injuries and were treated at the Department of Foot and Ankle Surgery, Ninth People's Hospital of Wuxi City. Nine injuries of foot skin avulsion were on the left feet and 11 on the right. All patients underwent a primary in situ replantation of the avulsed skin, and a stage-II surgery based on clinical manifestations and combined together with plantar pressure analysis in order to design a contralateral free medial plantar flap for reconstruction of the weight-bearing area of the affected foot. Eleven patients received the reconstructive surgery for forefoot weight-bearing area, and 9 had the reconstructive surgery for the heel weight-bearing area. The flap sizes ranged from 4 cm×4 cm to 13 cm×8 cm. All flap donor sites were closed with full-thickness skin grafts from ipsilateral thigh. Scheduled postoperative follow-ups at outpatient clinic were conducted to observe the flap survival, appearance and texture of the foot skin. American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot functional scores and the British Medical Research Council (BMRC) sensory function scale for flap sensation evaluation were used for assessment of the surgical outcomes, as well as the patient satisfaction. Pre- and postoperative plantar pressure analyses were performed to compare the weight-bearing area, load ratio and average plantar pressure. Statistical analysis was conducted using One-way ANOVA and Chi-square tests. P<0.05 was considered statistically significant. Results:The postoperative follow-up lasted for 10 to 24 months, with an average of 12.1 months. All 20 flaps survived. The flap swelling, appearance and wear resistance were good with AOFAS scores at 70 - 88 points. The sensation recovery reached S 2 to S 3. Patient satisfaction was excellent in 19 patients and good in 1 patient. The preoperative weight-bearing area was measured at 84 cm 2 to 140 cm 2, and 93 cm 2 to 145 cm 2 after surgery. The preoperative load ratio was 25% to 40%, and 30% to 43% after surgery. The preoperative plantar pressure was 185 grams/cm 2 to 356 grams/cm 2, and that was 205 grams/cm 2 to 381 grams/cm 2 after surgery. The postoperative weight bearing area, load ratio and mean plantar pressure of the patients were found all superior to those before surgery, with statistically significant differences ( P<0.05). Conclusion:In primary surgery, the avulsed skin is in situ replanted meanwhile have the original plantar skin preserved as much as possible. In the stage-II surgery, a contralateral medial free plantar flap is precisely designed to reconstruct the foot weight-bearing area, according to the healing of the in situ replanted skin and the wear resistance of the skin in weight-bearing area, and an analysis of plantar pressure should be performed. This is a reliable surgical procedure in the treatment of a degloving injury of whole foot.

From 2019 to 2023, a total of 30.8602 million doses of non-National Immunization Program (non-NIP) vaccines were administered in Shaanxi Province, averaging 1 561 doses per 10 000 population. The annual administration of non-NIP vaccines increased from 4.359 1 million doses in 2019 to 7.858 2 million doses in 2023, with their proportional representation among all vaccines rising from 30.82% to 55.15%( χ2 trend=2 440 581.54, P<0.001). The administration rate per 10 000 population increased from 1 105 doses to 1 986 doses during this period( χ2 trend=373.10, P<0.001). Concurrently, the substitution rate of non-NIP vaccines for National Immunization Program vaccines rose from 4.94% in 2019 to 16.11% in 2023.

Objective:To identify candidate strains of Nontoxigenic Clostridioides difficile (NTCD) with potential for intervention in Clostridioides difficile infection (CDI) and analyze their phenotypic characteristics. Methods:A total of 713 Clostridioides difficile strains from various sources were systematically collected nationwide between 2015 and 2023. This included 649 strains isolated from human fecal samples and 64 strains isolated from the fecal samples of farmed animals. NTCD strains were preliminarily screened through toxin gene detection and antibiotic sensitivity test, and then NTCD candidate strains with potential for intervention in CDI were screened by a series of in vitro experiments, including MLST, sporulation, germination, adhesion, motility, and biofilm formation ability. Ultimately, the virulence genes and antimicrobial resistance genes of the candidate strains were comprehensively analyzed to rigorously assess their safety profiles. Results:Among 713 strains of C. difficile from different sources, 10 strains were initially screened out, which were non-toxin-producing and sensitive to antibiotics. MLST showed that seven strains were from the Clade1 branch and three strains were of a novel type. The results of sporulation and germination showed that SD59, SD178, SJZ17, and WZ142 had stronger sporulation and germination abilities. The adhesion of 10 strains was high, and the adhesion rate was between 72.93% and 99.32%. The motility of all strains was different, and the motility of SD178, SD59 and SJZ17 was stronger. The biofilm-forming ability of all strains was weak. SD59, SD178 and SJZ17 carried a limited number of virulence and resistance genes, thereby posing a relatively low safety risk. Conclusion:Three NTCD strains are successfully selected as potential effective NTCD strains to interfere with CDI.
