Objective To clarify the risk factors of diaphragmatic dysfunction (DD) after cardiac surgery with extracorporeal circulation. Methods A retrospective analysis was conducted on the data of patients who underwent cardiac surgery with extracorporeal circulation in the Department of Cardiovascular Surgery of Peking University People's Hospital from January 2023 to March 2024. Patients were divided into two groups according to the results of bedside diaphragm ultrasound: a DD group and a control group. The preoperative, intraoperative, and postoperative indicators of the patients were compared and analyzed, and independent risk factors for DD were screened using multivariate logistic regression analysis. Results A total of 281 patients were included, with 32 patients in the DD group, including 23 males and 9 females, with an average age of (64.0±13.5) years. There were 249 patients in the control group, including 189 males and 60 females, with an average age of (58.0±11.2) years. The body mass index of the DD group was lower than that of the control group [(18.4±1.5) kg/m2 vs. (21.9±1.8) kg/m2, P=0.004], and the prevalence of hypertension, chronic obstructive pulmonary disease, heart failure, and renal insufficiency was higher in the DD group (P<0.05). There was no statistical difference in intraoperative indicators (operation method, extracorporeal circulation time, aortic clamping time, and intraoperative nasopharyngeal temperature) between the two groups (P>0.05). In terms of postoperative aspects, the peak postoperative blood glucose in the DD group was significantly higher than that in the control group (P=0.001), and the proportion of patients requiring continuous renal replacement therapy was significantly higher than that in the control group (P=0.001). The postoperative reintubation rate, tracheotomy rate, mechanical ventilation time, and intensive care unit stay time in the DD group were higher or longer than those in the control group (P<0.05). Multivariate logistic regression analysis showed that low body mass index [OR=0.72, 95%CI (0.41, 0.88), P=0.011], preoperative dialysis [OR=2.51, 95%CI (1.89, 4.14), P=0.027], low left ventricular ejection fraction [OR=0.88, 95%CI (0.71, 0.93), P=0.046], and postoperative hyperglycemia [OR=3.27, 95%CI (2.58, 5.32), P=0.009] were independent risk factors for DD. Conclusion The incidence of DD is relatively high after cardiac surgery, and low body mass index, preoperative renal insufficiency requiring dialysis, low left ventricular ejection fraction, and postoperative hyperglycemia are risk factors for DD.

Objective To investigate the serum levels of thyroid function and hs-CRP expression in patients with syphilis and their relationship with coagulation function. Methods A total of 80 syphilis patients admitted to Bazhong Central Hospital from January 2020 to January 2022 were selected as the study subjects and set as the observation group. In addition, 80 healthy individuals were selected as the control group, and 80 psoriasis patients were selected as the disease control group. Thyroid function, hs-CRP and coagulation function among different groups were compared. The correlation between thyroid function, hs-CRP, and coagulation function in patients with syphilis was analyzed, and the effectiveness of these parameters in predicting syphilis was analyzed. Results The values of FT3, FT4, TSH and hs-CRP in the observation group were higher than those in the control group and the disease control group (P<0.05). The abnormal rates of thyroid function and hs-CRP level in the observation group were higher than those in the control group and the disease control group (P<0.05). PT, APTT, and TT of the observation group were higher than those of the control group and the disease control group (P<0.05). The abnormal rate of coagulation function in the observation group was higher than that in the control group and the disease control group (P<0.05). The levels of FT3, FT4, TSH, hs-CRP, PT, APTT, and TT in the first stage were lower than those in the second and third stages, while these parameters in the secondary stage were lower than those in the third stage (P<0.05). The severity of syphilis was positively correlated with FT3, FT4, hs-CRP, APTT, and TT (P<0.05). Among these indicators, TT was more effective in the diagnosis of syphilis. Conclusion Syphilis patients have hyperthyroidism, accompanied by coagulation dysfunction and abnormal increase in hs-CRP, which are all related to the condition of syphilis patients. The combined prediction of syphilis patients has high effectiveness.

Objective To explore the construction and visualization for knowledge graph of Ling Shu(Spiritual Pivot),with a view to providing ideas for the structured storage and display of the theoretical knowledge of the ancient Chinese medical books.Methods Using the professional idea of constructing knowledge graphs for reference,text mining technology was applied to construct the thesaurus,and then word division,entity recognition,and relationship extraction for the original text of Ling Shu were performed to get the elements of knowledge graph construction.The graph database Neo4j was used for the storage and query of the knowledge graph,and then the visual display of the knowledge graph was achieved.Results The 1 216 high-quality words consisting of the thesaurus of Ling Shu were obtained,and the construction of the knowledge graph of the theory of Ling Shu was realized.The constructed knowledge graph basically displayed the traditional Chinese medicine theories such as the correlation of visceral manifestations with essence qi,and the relationship between emotions and the five-zang organs described in Ling Shu,which made the retrieval and utilization of the related entities and relationships possible,and provided ideas for the structured storage and display of the theoretical knowledge of the ancient books of Chinese medicine.Conclusion The knowledge graph construction technology can be used to obtain the Chinese medicine theoretical knowledge graph of Ling Shu,and to display the knowledge connections of yin-yang and the five elements,and the internal organs and meridians expressed in the Ling Shu.The construction of the knowledge graph and its storage in the graph database enable the knowledge graph involved in the text of Ling Shu to be displayed in the form of visualized semantic network graph,and also make the embedding of other search systems such as the semantic search and semantic wiki possible,which will be helpful for the development of Chinese medicine intelligent medical services.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Objective To discuss the application effect of using a stone extractor balloon catheter to assist in crossing the anastomotic stenosis in treatment of anastomotic biliary stenosis after liver transplantation using endoscopic retrograde cholangiopancreatography(ERCP).Methods Clinical data of 48 patients who developed anastomotic biliary stenosis after liver transplantation and underwent ERCP treatment were collected.Upon unsuccessful use of a dilation catheter to cross the stricture,attempts were made to cross the anastomotic biliary stenosis by using a stone extractor balloon catheter.The success rate of the procedure was recorded,intraoperative conditions were observed,treatment outcomes and complications were analyzed.Results The main presenting symptoms in the 48 patients on admission were abdominal discomfort(32 patients),fever(7 patients),pruritus(4 patients),jaundice(3 patients),and no obvious symptoms(2 patients).Preoperative magnetic resonance cholangiopancreatography(MRCP)examination revealed isolated stricture of the anastomotic site in 35 cases,and stricture associated with stones in 13 cases.Using the stone extractor balloon catheter as a guide,guidewire crossing of the anastomotic stenosis was successful in 26 cases,resulting in a success rate of 54.17%(26/48).Through statistical analysis of the successful group and the failed group,there was a significant difference in whether the distal biliary dilatation between the two groups,and the difference was statistically significant(χ2 = 8.39,P = 0.004).In the 26 successfully treated cases,alanine transaminase(ALT),aspartate transaminase(AST),γ-glutamyl transpeptidase(γ-GT),alkaline phosphatase(ALP),and total bilirubin(TBiL)levels decreased significantly 48 hours after the procedure(P<0.05),and no serious complications occurred.Conclusion The use of a stone extractor balloon catheter significantly increases the success rate of crossing anastomotic stenosis in the treatment of anastomotic biliary stenosis after liver transplantation,especially in cases with distal dilatation of the common bile duct.This approach is safe and worth promoting.

Objective:This study discusses the job preferences of Center for Disease Control and Prevention(CDC)staffs at the prefectural-level,and provides a basis for the development of an effective incentive mechanism.Method:This study used a combination of stratified sampling and purposive sampling to research online 455 staffs from six prefectural-level CDCs in Shandong Province,analyzed the data using a mixed logit model and latent class model,and calculated willingness to pay and relative importance.Result:In the mixed logit model,income,benefit level,establishment,workload,recognition and respect from the public,personal career development opportunities,and training opportunities all had significant influences(P<0.05)on the job selection preferences of the CDC staffs,with hygiene factors such as establishment(β =2.636)and income(β =0.083)having a greater degree of influence than motivation factors.The latent class model shows that relatively young CDC staffs with lower monthly incomes value income more;older CDC staffs with higher monthly incomes value establishment more.Conclusion:Prefectural-level CDC staffs prefer jobs with establishment,higher incomes,very good benefit levels,recognition and respected from the public,lower workloads,many opportunities for personal career advancement and abundant training opportunities.It is recommended that the total number of establishments be rationally controlled and dynamically adjusted to balance the differences between working conditions within and outside the establishment and that the financial input to CDC be increased and the pay performance system be improved;that attention be paid to both hygiene factors and motivation factors,and that a variety of measures work together to incentivize CDC staffs development;and that differentiated incentives be adopted for different categories of CDC staffs.

Objective To observe the effect and survival benefits of camrelizumab combined with chemotherapy in the treatment of advanced esophageal squamous cell carcinoma(ESCC).Methods Patients with advanced ESCC were divided into control group and treatment group.The control group was given albumin-paclitaxel(260 mg·m-2,qd,intravenous drip on the 1st day)and cisplatin(20 mg·m-2,once a day,intravenous drip on the 1 st-5 th day),while treatment group was given camrelizumab(200 mg,qd,intravenous drip on the 1st day)on basis of control group.All patients were treated for 4 cycles(21 d/cycle).The curative effect(disease control rate,objective response rate),immune function(CD4+,CD8+,CD4+/CD8+),tumor markers(carbohydrate antigen 199,carcinoembryonic antigen,carbohydrate antigen 125),safety and survival benefits in the two groups were compared after treatment.Results There were 48 cases in treatment group and 42 cases in control group.After treatment,disease control rates in treatment group and control group were 79.17％(38 cases/48 cases)and 57.14％(24 cases/42 cases),objective response rates were 62.50％(30 cases/48 cases)and 40.48％(17 cases/42 cases),the differences were statistically significant(all P＜0.05).After treatment,levels of peripheral blood CD4+/CD8+levels were 1.11±0.29 and 1.87±0.38;levels of levels of serum carbohydrate antigen 199 were(50.03±6.21)and(36.41±4.87)ng·mL-1;levels of serum carcinoembryonic antigen were(21.25±3.39)and(14.97±2.85)ng·mL-1;levels of serum carbohydrate antigen 125 were(29.82±4.16)and(20.63±3.34)ng·mL-1,the differences were statistically significant(all P＜0.05).The differences in 6-month survival rate between treatment group and control group were statistically significant[95.83％(46 cases/48 cases)vs 80.95％(34 cases/42 cases),P＜0.05].The adverse drug reactions of the two groups were mainly proteinuria,abnormal liver function,bone marrow suppression,abnormal thyroid function and gastrointestinal reaction,and there was no significant difference in the incidence of adverse drug reactions between the two groups(P＞0.05).Conclusion Camrelizumab combined with chemotherapy can enhance immune function in patients with advanced ESCC,inhibit the expressions of tumor markers and increase survival rate.

Objective:To analyze the epidemiological characteristics and pathogen spectrum of influenza outbreaks in Shaanxi Province from 2014 to 2023 and provide basis reference for strengthening regional influenza prevention and control.Methods:The data were collected from the Public Health Emergency Management Information System of the China Disease Prevention and Control Information System and the China Influenza Surveillance Information System. On-site epidemiological investigation information and etiological test results of influenza network laboratories reported in Shaanxi Province during 2014-2023 were collected, and descriptive analysis was conducted on the time, region, and location distribution of influenza outbreaks. SPSS 25.0 software was used for statistical analysis.Results:A total of 386 influenza outbreaks were reported in Shaanxi from 2014 to 2023, with a total attack rate of 1.81% (14 880/821 001). The epidemic peaks mainly occurred in winter and spring (November to March of the following year), and there was an alternating pattern of epidemic peaks in different years (the early peak was in December, and the late peak was in March of the following year). The epidemic areas were mainly concentrated in the Qinba Mountains of southern Shaanxi (209, 54.15%) and Guanzhong Plain (173, 44.82%). The epidemic places were mainly distributed in primary schools (239, 61.92%), and the differences of epidemic areas and places were statistically significant (all P<0.001). Influenza A(H3N2) viruses were the predominant pathogen in the outbreak (849, 57.76%), and influenza A(H3N2), B (Victoria) lineage and A(H1N1)pdm09 virus alternately dominated the epidemic peak in different years. Conclusions:The peak of influenza outbreaks in Shaanxi Province was winter and spring during 2014-2023. Primary schools in the Qinba Mountains of southern Shaanxi and Guanzhong Plain should be targeted for prevention and control. In the prevention and control programs, close attention should be paid to the changing trend of dominant strains. Effective intervention measures should be targeted to the high-incidence areas and seasons.
