PURPOSE: We carried out the study aiming to explore and analyze the risk factors, the distribution of pathogenic bacteria, and their antibiotic-resistance characteristics influencing the occurrence of surgical site infection (SSI), to provide valuable assistance for reducing the incidence of SSI after traumatic fracture surgery. METHODS: A retrospective case-control study enrolling 3978 participants from January 2015 to December 2019 receiving surgical treatment for traumatic fractures was conducted at Tangdu Hospital of Air Force Medical University. Baseline data, demographic characteristics, lifestyles, variables related to surgical treatment, and pathogen culture were harvested and analyzed. Univariate analyses and multivariate logistic regression analyses were used to reveal the independent risk factors of SSI. A bacterial distribution histogram and drug-sensitive heat map were drawn to describe the pathogenic characteristics. RESULTS: Included 3978 patients 138 of them developed SSI with an incidence rate of 3.47% postoperatively. By logistic regression analysis, we found that variables such as gender (males) (odds ratio (OR) = 2.012, 95% confidence interval (CI): 1.235 - 3.278, p = 0.005), diabetes mellitus (OR = 5.848, 95% CI: 3.513 - 9.736, p < 0.001), hypoproteinemia (OR = 3.400, 95% CI: 1.280 - 9.031, p = 0.014), underlying disease (OR = 5.398, 95% CI: 2.343 - 12.438, p < 0.001), hormonotherapy (OR = 11.718, 95% CI: 6.269 - 21.903, p < 0.001), open fracture (OR = 29.377, 95% CI: 9.944 - 86.784, p < 0.001), and intraoperative transfusion (OR = 2.664, 95% CI: 1.572 - 4.515, p < 0.001) were independent risk factors for SSI, while, aged over 59 years (OR = 0.132, 95% CI: 0.059 - 0.296, p < 0.001), prophylactic antibiotics use (OR = 0.082, 95% CI: 0.042 - 0.164, p < 0.001) and vacuum sealing drainage use (OR = 0.036, 95% CI: 0.010 - 0.129, p < 0.001) were protective factors. Pathogens results showed that 301 strains of 38 species of bacteria were harvested, among which 178 (59.1%) strains were Gram-positive bacteria, and 123 (40.9%) strains were Gram-negative bacteria. Staphylococcus aureus (108, 60.7%) and Enterobacter cloacae (38, 30.9%) accounted for the largest proportion. The susceptibility of Gram-positive bacteria to Vancomycin and Linezolid was almost 100%. The susceptibility of Gram-negative bacteria to Imipenem, Amikacin, and Meropenem exceeded 73%. CONCLUSION Orthopedic surgeons need to develop appropriate surgical plans based on the risk factors and protective factors associated with postoperative SSI to reduce its occurrence. Meanwhile, it is recommended to strengthen blood glucose control in the early stage of admission and for surgeons to be cautious and scientific when choosing antibiotic therapy in clinical practice.

Chronic heart failure is the final stage of various cardiovascular diseases,and mitochondrial energy metabolism disorders have been proved to play an important role in the development of chronic heart failure.TCM believes that heart yin is the material basis of heart yang(qi),and deficiency of heart yang(qi)is the core pathogenesis of chronic heart failure.Based on mitochondrial energy metabolism,this article expounded the scientific connotation of"reinforcing yang from yin"in the treatment of chronic heart failure from the aspects of theoretical connotation,pathogenesis,pathophysiological relationship and modern research.In-depth study at the microscopic level demonstrated that the application of"reinforcing yang from yin"method can effectively improve the reconstruction of heart energy substrate(yin),enhance mitochondrial function,and finally provide energy support(yang),which could offer ideas for theoretical research and clinical prevention and treatment of chronic heart failure.

ObjectiveTo investigate the effect of mucin 1 (MUC1) on the proliferation and apoptosis of nasopharyngeal carcinoma (NPC) and its regulatory mechanism. MethodsThe 60 NPC and paired para-cancer normal tissues were collected from October 2020 to July 2021 in Quanzhou First Hospital. The expression of MUC1 was measured by real-time quantitative PCR (qPCR) in the patients with PNC. The 5-8F and HNE1 cells were transfected with siRNA control (si-control) or siRNA targeting MUC1 (si-MUC1). Cell proliferation was analyzed by cell counting kit-8 and colony formation assay, and apoptosis was analyzed by flow cytometry analysis in the 5-8F and HNE1 cells. The qPCR and ELISA were executed to analyze the levels of TNF-α and IL-6. Western blot was performed to measure the expression of MUC1, NF-кB and apoptosis-related proteins (Bax and Bcl-2). ResultsThe expression of MUC1 was up-regulated in the NPC tissues, and NPC patients with the high MUC1 expression were inclined to EBV infection, growth and metastasis of NPC. Loss of MUC1 restrained malignant features, including the proliferation and apoptosis, downregulated the expression of p-IкB、p-P65 and Bcl-2 and upregulated the expression of Bax in the NPC cells. ConclusionDownregulation of MUC1 restrained biological characteristics of malignancy, including cell proliferation and apoptosis, by inactivating NF-κB signaling pathway in NPC.

Background and purpose:Colorectal cancer(CRC)is globally recognized as one of the most prevalent malignant tumors.Advanced CRC is marked by a relatively poor prognosis for patients,signifying an urgent need to identify novel potential biomarkers for CRC.A particular focus has been given to circulating tumor cells(CTC),which are cells that have detached from the primary tumor mass and subsequently entered the circulatory system.These cells can be detected within the blood and are currently considered significant potential biomarkers for CRC.This study aimed to investigate if FCGBP and BIGH3 in CRC could be potential markers for colorectal cancer.Methods:This study obtained 3 CRC datasets(GSE74369,GSE117606,and GSE164191)with CTC from the GEO database.Bioinformatics analysis was conducted to screen differentially expressed genes between CTC and normal samples.One dataset that includes clinical information was used for WGCNA analysis,and two key gene modules were identified,containing 1 148 genes in total.Then,functional enrichment analysis was carried out for these genes in the modules.Venn diagrams,PPI network construction analysis,and candidate gene screening were employed.Finally,survival analysis was performed using TCGA and GTEx data in the GEPIAS database,and key genes associated with CRC were identified.The expression of BIGH3 gene was validated in colorectal cancer tissues by real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR),and its association with colorectal cancer was verified through clonogenic,scratch,and transwell assays in HCT116 and SW620 cell lines.Results:Through the analysis of CRC datasets from GEO,we screened a total of 2 214 differential genes.With the help of WGCNA analysis and PPI network construction,4 CTC-related genes associated with CRC were identified.Survival analysis from the GEPIA database revealed that FCGBP and BIGH3 are associated with overall survival and disease-free survival.Further experiments indicated that BIGH3 gene is overexpressed in 30 matched colorectal cancer samples.The downregulation of BIGH3 expression could slow down cell proliferation and migration rates,as well as decrease invasiveness in HCT116 and SW620 cell lines.In contrast,upregulation of BIGH3 expression could increase its invasiveness or accelerate migration rate.Conclusion:FCGBP and BIGH3 are positively correlated with TNM staging,indicating their pivotal roles in CRC progression.They bear good prognostic value and may serve as potential biological markers for CRC clinically,and could provide potential therapeutic targets.Moreover,our experimental data revealed the crucial role of BIGH3 in colorectal cancer,suggesting it may influence the biological behavior of this disease.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

The study employed network Meta-analysis to evaluate the efficacy and safety of Chinese patent medicines combined with recombinant human interferon α-2b(interferon) in the treatment of cervical human papillomavirus(HPV) infections. The relevant randomized controlled trial(RCT) published from inception to May 8, 2024 were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science. The modified Jadad scale and the Cochrane risk of bias tool were used to evaluate the quality of the included studies, and RevMan 5.4, R 4.3.3, and Stata 17 were used for data analysis. A total of 105 RCTs were included, involving 12 732 participants and 7 Chinese patent medicines: Baofukang Suppository, Compound Seabuckthorn Seed Oil Suppository, Huangqi Shengmai Decoction, Kangfu Gel, Kangfuyan Capsules, Kushen Gel, and Puling Penyankang Granules. Network Meta-analysis yielded the following results:(1)For improving the negative conversion rate of HPV, SUCRA top-ranked intervention was Puling Penyankang Granules + interferon.(2) For shortening vaginal discharge time, SUCRA top-ranked intervention was Compound Seabuckthorn Seed Oil Suppository + interferon.(3) For reducing the serum level of hypersensitive C-reactive protein(hs-CRP), SUCRA top-ranked intervention was Baofukang Suppository + interferon.(4) For elevating the serum level of CD~+_4 T cells, SUCRA top-ranked intervention was Baofukang Suppository + interferon.(5) For elevating the serum level of CD~+_8 T cells, SUCRA top-ranked intervention was Kangfuyan Capsules + interferon.(6) For improving the CD~+_4/CD~+_8 ratio, SUCRA top-ranked intervention was Compound Seabuckthorn Seed Oil Suppository + interferon.(7)In terms of reducing serum tumor necrosis factor-α(TNF-α), interleukin-6(IL-6), recurrence rate at 6 months after treatment, and incidence of adverse events, there were no significant differences between the interventions when compared pairwise. The cluster analysis revealed that Puling Penyankang Granules + interferon, Baofukang Suppository + interferon, Kangfu Gel + interferon, and Huangqi Shengmai Decoction + interferon simultaneously improved the negative conversion rate of HPV and reduced the incidence of adverse events. The findings suggested that Chinese patent medicines combined with interferon were effective in treating cervical HPV infection by enhancing the negative conversion rate, shortening the vaginal discharge time, and improving the levels of hs-CRP and T lymphocyte subsets. However, due to the limitations of sample size and quality of the included studies, these conclusions require further validation by studies with larger sample sizes and higher quality.

Objective:To analyze the DIP medical insurance settlement situation of neonatology and its influencing factors,to optimize the medical insurance settlement rules of neonatology,and to promote the fine management of payment method reform.Methods:City Y,the pilot city of national DIP payment method,was selected as the case area,and the data of the whole sample of patients in neonatology department of City Y were analyzed by descriptive analysis,four-quadrant bubble chart,and multivariate linear regression methods,combined with qualitative data analysis and interview study.Results:There were 1 372 neonates in City Y in 2022,with a health insurance billing rate of 84.82%and 81.10%in tertiary care facilities.There were 718 unenrolled cases.Tertiary care institutions,not enrolled,low-birth-weight babies,higher days of hospitalization,lower days of birth,and lower settlement scores were the influencing factors for the low rate of health insurance settlement in neonatology(P<0.05).Conclusion:Neonatology medical insurance settlement rate was significantly lower than that of the city,and tertiary care institutions had higher deficits,which may lead to the risk of shirking critically ill neonatal patients.There were problems of insufficient grouping refinement and score distortion in neonatology.Recommendation:We should improve the management and adjustment mechanism of core elements,optimize the DIP grouping of neonatology,comprehensively consider the resource consumption characteristics of neonates,rationally and dynamically adjust the price of neonatal medical services,and scientifically set the neonatology markup coefficients,so as to achieve synergistic improvement in the development of neonatology and health insurance,and to push forward the connotative and refined development of the reform of the payment method of health insurance.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

OBJECTIVES: To compare the application effect of microwave digestion - vacuum filtration - automated scanning electron microscopy (MD-VF-Auto SEM) method and plankton gene multiplex PCR system in the diagnosis of drowning. METHODS: Lung, liver and kidney tissue of 10 non-drowning cases and 50 drowning cases were prepared for further MD-VF-Auto SEM method analysis and plankton gene multiplex PCR system analysis. The positive detection rate of the two methods in each tissue was calculated. RESULTS: The positive rate of the MD-VF-Auto SEM method detecting diatoms in drowning cases was 100%, and few diatoms were detected in the liver and kidney tissues of 6 non-drowning cases. By using the plankton gene multiplex PCR system, the diatom positive rate of drowning cases was 84%, and all the non-drowning cases were negative. There were significant differences in the positive rate of the liver, kidney tissues between MD-VF-Auto SEM method and plankton gene multiplex PCR system (P<0.05), as well as the total positive rate of cases. However, no significant differences were found in the positive rates of lung tissues (P>0.05). CONCLUSIONS MD-VF-Auto SEM method is more sensitive than plankton gene multiplex PCR system in diatom test. But the plankton gene multiplex PCR system can also detect plankton other than diatoms. Combination of the two methods can provide a more reliable basis for the diagnosis of drowning.
