OBJECTIVE To analyze the safety and efficacy of vonoprazan （VPZ） in the treatment of peptic ulcer （PU） and post-endoscopic submucosal dissection （ESD） ulcers， providing evidence-based pharmaceutical evidence for clinical practice and medical decision-making. METHODS Retrieved from CNKI， Wanfang， VIP， CBM， PubMed， Embase， Web of Science， and the Cochrane Library， meta-analyses/systematic reviews related to VPZ in the treatment of PU and post-ESD ulcers were collected. Two researchers independently performed literature screening， data extraction， quality assessment of included studies， and evaluation of literature overlap. By employing the umbrella review analysis， a fresh meta-analysis was conducted on all relevant raw research data when a high degree of overlap was identified among the included studies. RESULTS A total of 17 meta-analyses were included， with quality ranging from high to very low； all outcome measures involved showed a very high level of overlap in the included meta-analyses （corrected covered area： 22.22%-100%）. In the treatment of post-ESD ulcers， compared to proton pump inhibitor （PPI）， VPZ significantly improved the ulcer healing rate at 4 weeks post-ESD [RR＝1.27， 95%CI （1.03， 1.56）， Z＝2.21， P＝ 0.027] and the ulcer contraction rate post-ESD [MD＝0.08， 95%CI （0.00， 0.16）， Z＝2.09， P＝0.037]， while significantly reducing the ulcer recurrence rate in patients with a history of PU [RR＝0.49， 95%CI （0.32， 0.73）， Z＝3.49， P＝0.001]； the delayed bleeding rate in the VPZ group was significantly lower than that in the lansoprazole subgroup [RR＝0.47， 95%CI （0.25， 0.90）， Z＝2.28， P＝0.02]. In the treatment of PU， the incidence of adverse events with VPZ was significantly higher than that with PPI in the duodenal ulcer subgroup [RR＝1.13， 95%CI （1.02， 1.26）， Z＝2.38， P＝0.017]. CONCLUSIONS For post-ESD ulcers， VPZ demonstrates superior therapeutic efficacy compared to PPI and can reduce ulcer recurrence rates in patients with a history of PU. However， it does not offer advantages in terms of safety for duodenal ulcer treatment.

OBJECTIVE To investigate the efficacy and safety of omadacycline in the treatment of macrolide-unresponsive Mycoplasma pneumoniae pneumonia （MUMPP） in children. METHODS A retrospective study was conducted on children aged 1-18 years old with MUMPP who were hospitalized in the Department of Pediatrics， the First Affiliated Hospital of Xinjiang Medical University from January 2022 to June 2025. According to the selection of secondary antibiotics after 72 h of initial treatment with macrolides， they were divided into the omadacycline group and the doxycycline group. Based on conventional treatment， children in the omadacycline group were given intravenous infusion of 2.4 mg/kg （once daily） of omadacycline tosylate， while children in the doxycycline group were given oral doxycycline hydrochloride tablets at 2 mg/kg （twice daily）. The efficacy and safety were compared between the two groups of pediatric patients. Univariate analysis and multivariate Logistic regression analysis were performed on clinical efficacy， and subgroup analysis along with multiple sensitivity analyses were conducted to verify the robustness of the conclusions. RESULTS A total of 284 children with MUMPP were included in this study， with 142 in the omadacycline group and 142 in the doxycycline group. In terms of efficacy， although the hospitalization time of children in the omadacycline group was longer than that in the doxycycline group （ P ＜0.05）， the lung lesion absorption rate and clinical efficacy were significantly higher or better than those in the doxycycline group （ P ＜0.05）. The results of multivariate Logistic regression analysis showed that medication （OR＝5.300， 95%CI： 2.526-11.123）， length of hospital stay （OR＝1.348， 95%CI： 1.167-1.556）， and medication duration （OR＝1.422， 95%CI： 1.169-1.729） were influencing factors of clinical efficacy （ P ＜0.05）. The subgroup analysis results showed that the clinical efficacy of omadacycline was significantly better than that of doxycycline in all subgroups （ P ＜0.05）. The results of multiple sensitivity analysis showed that the regression coefficients B of the four models （gradually adjust variables） before and after inverse probability of treatment weighting were significantly greater than 1 （ P ＜0.05）. In terms of safety， there was no statistically significant difference in the inci dence of adverse drug reactions between the two groups of patients （ χ 2 ＝0.447， P ＝0.504）. CONCLUSIONS In the case of hospitalization and prolonged medication， the efficacy of omadacycline in treating childhood MUMPP is superior to that of doxycycline， and its safety is good.

Chronic pain refers to pain that persists or recurs for more than 3 months and has a high comorbidity rate with emotions such as depression and anxiety. The complex pathogenesis of comorbid depressive symptoms in chronic pain poses great challenges to clinical diagnosis and treatment. This article reviews the research progress on the effect mechanism on the comorbid depressive symptoms in chronic pain by traditional Chinese medicine monomers， compound formulas， and acupuncture therapy in recent years. It is found that traditional Chinese medicine monomers （flavonoids， phenols， terpenes， coumarins， alkaloids）， traditional Chinese medicine formulas （Aconitum carmichaeli decoction， Chaihu guizhi decoction， etc.）， and acupuncture therapy （acupuncture at acupoints such as Baihui， Yintang， Hegu， and Taichong） can effectively improve comorbid depressive symptoms in chronic pain by regulating the levels of neurotransmitters， brain-derived neurotrophic factors and inflammatory factors， and the activity of glial cells in the central nervous system.

Objective To discuss the perioperative care and wound protection of xenotransplantation from genetically edited pigs to monkeys, with the goal of improving the success rate of such experimental procedures. Methods From October 2022 to October 2023, perioperative care and wound protection were performed on 7 recipient rhesus monkeys undergoing xenotransplantation of genetically edited pig tissues and organs. Customized wound protective garments were designed based on monkeys' size and surgical area to protect the wounds, alongside meticulous perioperative care. This included preoperative preparation and medication, intraoperative monitoring of physiological indicators and anesthesia management, and postoperative care comprising wound protection, observation and monitoring, and nutritional support. Results All seven monkeys successfully underwent xenotransplantation. With the aid of protective garments and detailed care, all surgical wounds healed by first intention, and postoperative recovery was satisfactory. Conclusion Proper care and wound protection during xenotransplantation from genetically edited pigs to monkeys not only promote wound healing, but also alleviate pain and harm to animals. This has significant implications for advancing experimental research in pig-monkey xenotransplantation and enhancing animal welfare.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective:To explore the differences of clinical features and surgical efficacy between the elderly and the middle-aged and young patients with meningiomas in the central cortex area.Methods:Forty-three elderly patients with meningiomas in the central cortex area (≥60 years old) and 63 middle-aged and young patients with meningiomas in the central cortex area (18-59 years old), accepted surgery in Department of Neurosurgery, Guangdong 999 Brain Hospital from January 2011 to December 2020, were chosen. The differences of symptom, gross tumor volume, peritumoral edema degrees, intraoperative blood loss, tumor resection degrees, complications, and hospital stays between the 2 groups were analyzed.Results:The elderly patients had significantly higher proportion of preoperative muscle strength decline, lower proportion of preoperative headache, larger preoperative tumor volume, more severe peritumoral edema degrees before and after surgery, small volume of intraoperative blood loss, and longer hospital stays compared with the middle-aged and young patients ( P<0.05). However, no significant differences in distributions of tumor resection Simpson grades, proportion of new neurological dysfunction, incidence of postoperative complications, and proportions of reoperations and tumor recurrence were noted between the 2 groups ( P>0.05). Significant difference in distributions of peritumoral edema degrees among patients with different WHO grades was noted in the elderly group ( P<0.05), and significant difference in distribution of peritumoral edema degrees among patients with different tumor volumes was noted in the middle-aged and young group ( P<0.05). Conclusions:Although differences in clinical characteristics exist between the elderly and the middle-aged and young patients with meningiomas in the central cortex area, no significant difference in surgical efficacy is noted between the 2 groups. The peritumoral edema degree in the elderly patients is related to tumor pathological grades, while that in middle-aged and young patients is related to tumor volumes.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective:To grasp the distribution of fine antigenic epitope profiles of nucleoprotein (NP) and glycoprotein (GP) fragments of Crimean-Congo hemorrhagic fever virus (CCHFV) and to clarify the value of dominant antigenic epitopes in laboratory testing of Crimean-Congo hemorrhagic fever (CCHF).Methods:In a minimal synthetic short peptide consisting of 8 amino acids was segmentally expressed by CCHFV YL04057 strain using a modified bio-peptide synthesis method from 2014 to 2021 in the laboratory of Xinjiang University, College of Life Sciences. Using CCHFV polyclonal antibody or monoclonal antibody 14B7 (IgM) or CCHFV-positive sheep serum as antibodies, the minimal antigenic epitopes (BCEs) with antigenic activity on NP and GP fragments were identified by immunoblotting, and the obtained BCEs with sequence polymorphism were spatially clustered with CCHFV from different regions using the neighbor-joining method to determine the combination mode of BCEs with geographical correlation of regional distribution, to explore its application in establishing serological diagnosis. A prokaryotic expression plasmid (pET-32a), an E. coli expression plasmid (pGEX-KG) and a prokaryotic expression plasmid with an incomplete glutathione (GST188) tag (pXXGST-ST-1) were used to construct and express six dominant antigenic epitopes of different peptide lengths on NP fragments, and an indirect Enzyme-linked immunosorbent assay (ELISA) was established. CCHF sheep serum identified by immunofluorescence assay (IFA) was used as a control, and the specificity, sensitivity and overall compliance of the recombinant proteins with different peptide lengths of antigenic epitopes with IFA assay results were statistically analyzed. Results:CCHFV, NP and GP fragments had a total of 30 antigenically active BCEs, among which the core intermediate fragment NP2 (aa 170 th-305 th), which had a concentration of antigenic epitopes in the NP fragment, has 6 BCEs, and the NP1 (aa 1 st-200 th) and NP3 (aa 286 th-482 nd) at both ends have 9 BCEs; the Gc (aa 1 st-558 th) and Gn (aa 533 th-708 th) fragments of the GP fragment have 14 BCEs and a long antigenic peptide (AP) containing 15 amino acids, and the amino acid sequence homology of the NP fragment BCEs was 97.1% and that of the GP fragment BCEs was 89.1%. There was a significant difference ( P=0.0281, P<0.05). Among the 9 BCEs with sequence polymorphism in the GP fragment, 6 combined BCEs from GnEc1, GnE2, GnE4, GcE3, GcE6 and GcAP-4 (Ap) could cluster 15 CCHFV strains from different regions of the world into 5 geographical taxa, AsiaⅠ, AsiaⅡ, AficaⅠ, AficaⅡ and Europe. The constructs expressing PET-32a-NP (full length), PGEX-KG-NP2 (aa 170 th-305 th), pGEX-KG-NP2-1 (aa 235 th-275 th), PGEX-KG-NP2-1-1 (aa 237 th-256 th), pXXGST-1-NP2-1-2 (aa 250 th-265 th) and PGEX KG-NP2-1-3 (aa 260 th-276 th), six recombinant proteins CCHFV NP rabbit polyclonal antiserum (pAb) Western Blotting reaction positive, 33 sheep sera tested by IFA XHF as a reference, the sensitivity of the assay established by indirect ELISA using the recombinant proteins constructed from two fragments of NP2 and NP2-1 as antigens. The sensitivity, specificity and overall compliance were the best, with 73.4% (11/15) and 66.7% (10/15) for sensitivity, 100% (18/18) and 94.4% (17/18) for specificity, and 87.9% (29/33) and 81.8% (27/33) for overall compliance. Conclusion:CCHFV NP and GP are distributed with a high number of BCEs with antigenic immunoreactivity, among which the dominant antigenic epitopes are of high value in the laboratory serological diagnosis of CCHF.

Objective:To measure the predictive value of miR-424 on the risk of sepsis complicated with acute respiratory distress syndrome(ARDS), and to explore its correlation with the prognosis of ARDS children.Methods:A prospective study was conducted.The data of children with sepsis (some complicated with ARDS), who were treated in Henan Provincial People′s Hospital (People′s Hospital, Zhengzhou University) were collected from February 2020 to February 2021.The incidence of ARDS and the fatality rate of ARDS children were recorded.Children were divided into survival group and death group according to whether death or not.The expression of miR-424 in peripheral blood mononuclear cells was detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR). Pearson correlation analysis was made to investigate the relationship between the expression level of miR-424 and Pediatric Critical Illness Score(PCIS), Sequential Organ Failure Assessment(SOFA) score, oxygenation index(P/F ratio), C-reactive protein(CRP), procalcitonin (PCT), interleukin 6 (IL-6) and interleukin 8 (IL-8). The factors affecting the prognosis of ARDS children were analyzed by multivariate Logistic regression.Receiver operating characteristic curve(ROC)was used to assess the accuracy of miR-424 in early diagnosis of sepsis complicated with ARDS, and to measure the predicative value of miR-424 on the risk of death in sepsis patients with ARDS. Results:A total of 121 sepsis patients were included in this study, and 36 cases of them were complicated with ARDS.The expression level of miR-424(0.56±0.17)in the blood of sepsis patients complicated with ARDS was significantly lower than that of sepsis patients without ARDS (0.98±0.26)( t=8.776, P<0.001). The expression of miR-424 was negatively co-rrelated with IL-6( r=-0.627, P<0.01), IL-8 ( r=-0.651, P<0.01) and CRP( r=-0.472, P<0.05)in sepsis patients with ARDS.The expression of miR-424 was positively correlated with PCIS score( r=0.330, P<0.05), P/F ratio ( r=0.592, P<0.001) and albumin ( r=0.496, P<0.05) in sepsis patients with ARDS.The ROC showed that miR-424 [area under curve(AUC)=0.908, 95% CI: 0.856-0.960] could differentiate sepsis patients with ARDS from those without ARDS.Compared with that of the survival group(0.63±0.15), miR-424 of the death group decreased significantly(0.42±0.14)( t=3.890, P<0.05). The decreased miR-424 (AUC=0.845, 95% CI: 0.696-0.995)indicated an increased risk of death in children with ARDS.Multivariate Logistic regression analysis showed that miR-424( OR=0.001, P=0.033)and albumin ( OR=0.553, P=0.040) were independent risk factors for death in ARDS children. Conclusions:miR-424 can help with early diagnosis of sepsis complicated with ARDS, and can be used as a predictor of the prognosis of sepsis children complicated with ARDS.

Objective:To understand the social networking using status of medical students, develop the social networking using status scale (SNUSS) and evaluate its reliability and validity.Methods:In March 2018, 665 valid questionnaires were collected via cluster sampling. The scale was retest in 46 subjects after an interval of 2 months. Factor analysis, correlation analysis and t-test were used to calculate the structure validity and content validity of the scale to evaluate the scale validity, and internal consistency reliability, broken half reliability and retest reliability were used to evaluate the scale reliability. Results:The result of exploratory factor analysis showed NSUSS had two subscales: the dimension of maintaining existing social relations and social network use and the dimension of expanding circle of friends and social network use. The result of confirmatory factor analysis showed that the factor load value of each item was greater than 0.500 ( P < 0.05), and the model fitted well ( χ2/ df = 2.873, GFI = 0.970, CFI = 0.971, RMSEA = 0.074). The r value of correlation between SNUSS and MSPSS was 0.295. I-CVIs were all equal to 0.90, and S-CVI was 0.90, the internal consistency reliability was 0.764, the split-half reliability was 0.555, and the retest reliability was 0.526. Conclusion:SNUSS has good reliability and validity for the use of social network among medical college students, and the use of social network is related to perceived social support.
