Objective:To select the differential prognostic lactic acid metabolism-related genes(LRGs)of the head and neck squamous cell carcinoma(HNSCC)to construct the LRGs prognostic model of HNSCC,and to clarify the potential mechanism.Methods:The HNSCC gene expression and clinical data were obtained from The Cancer Genome Atlas(TCGA)and Gene Expression Omnibus(GEO)Databases,the LRGs were identified through GeneCards Database,and R software was used to screen out the LRGs of HNSCC;univariate Cox regression analysis was used to identify prognosis-related genes;two different subtypes were identified based on the prognostis-related LRGs;Kaplan-Meier(K-M)curve analysis was used to compare the prognosis of the patients between two groups;CIBERSORT algorithm was used to perform the immuno-correlation analysis between two groups;multivariate Cox regression analysis and LASSO regression analysis were used to construct the prognostic model;receiver operating characteristic curve(ROC)and K-M survival curve were used to assess the relationship between LRGs and survival and prognosis of the HNSCC patients.The prognostic model was validated by GSE27020,GSE41613,and GSE65858 datasets.The experiment were grouped based on risk score,and immune-related analysis and tumor score analysis were performed.Results:The TCGA Database differential analysis results showed that 1 196 LRGs were identified from HNSCC samples;univariate Cox regression analysis selected 27 differentially expressed genes(DEGs)associated with the prognosis of the HNSCC patients.Two different LRGs subtypes(Group 1 and Group 2)were identified according to the prognosis-related genes.The K-M survival curves results showed that the overall survival(OS)of the patients in Group 2 was significantly higher than that in Group 1,and the immune cell expression amount of the patients in Group 2 was also higher than that in group 1.The multivariate Cox regression and LASSO regression analysis results screened out 9 LRGs,including hypoxanthine phosphoribosyltransferase 1(HPRT1),amyloid precursor protein(APP),glycogen phosphorylase L(PYGL),urokinase-type plasminogen activator(PLAU),cannabinoid receptor 2(CNR2),stanniocalcin 2(STC2),nucleotide binding oligomerization domain-like receptor protein 1(NLRP1),integrin-linked kinase(ILK),and forkhead box B1(FOXB1);the prognostic model was constructed.The K-M and ROC curve results indicated that the expression levels of above 9 genes were associated with the survival and prognosis of the HNSCC patients,providing good 1-year,2-year,and 3-year survival prediction effect,and the area under ROC curve(AUC)values were all greater than 0.650.Furthermore,the predictive ability of the prognosis model was validated in GSE27020,GSE41613,and GSE65858 datasets.The patients classified based on the risk scores had distinguishable immune statuses.Conclusion:The differentially expressed LRGs of HNSCC screened by bioinformatics methods are related to the survival and prognosis of the HNSCC patients;the prognostic model constructed by 9 LRGs can predict the survival status and treatment response of the HNSCC patients.

Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.

Objective:To analyze the effect of birth parity on life expectancy (LE) and healthy life expectancy (HLE) among rural women.Method:A total of 15 304 women aged 40 to 79 years who participated in baseline and follow-up surveys were selected from a rural cohort in Henan province. The LE and HLE of women with different birth parity were calculated by using multi-state life table.Results:There were 1 195 (7.8%), 7 782 (50.8%), 3 867 (25.3%) and 2 460 (16.1%) women with 1, 2, 3 and 4 birth parities, respectively, and the M ( Q1 and Q3) of age were 50.3 (47.3, 53.4) and 53.3 (48.8, 60.7), 62.6 (55.4, 66.9) and 69.5 (64.7, 73.4) years old, respectively. LE at 40 years old was 44.5, 44.8, 45.1 and 45.4 years old, and HLE was 17.7, 18.3, 18.8 and 19.3 years old, respectively. LE at age 40 increased by 0.3, 0.6, and 0.9 years in women with 2, 3, and 4 birth parities or more and HLE increased by 0.5, 1.1, and 1.6 years, respectively, compared with women with 1 birth parity. For women with higher and lower socioeconomic status who had 4 birth parities or more, the LE at age 40 was 47.1 and 43.9 years, respectively, an increase of 0.2 and 0.1 years over women with 1 birth parity, respectively; and the HLE was 20.4 and 18.7 years, respectively, an increase of 1.4 and 1.3 years over women with 1 birth parity, respectively. Conclusion:LE and HLE show an upward trend with the increase of birth parity among rural women.

Objective:To construct the clinical practice pathway for narrative medicine in traditional Chinese medicine(TCM),with a view to providing clinical practice guidelines for narrative medicine in TCM for frontline practitioners.Methods:Using the realistic literature review and the Nominal Group Technique(NGT),the paper systematically sorted out the practices of humanistic care in ancient Chinese medical books and famous medical cases,as well as constructed the first draft of the clinical practice pathway and details for narrative medicine in TCM.Subsequently,experts from multiple fields were invited to demonstrate by using the NGT.After in-depth discussion and collective voting,various operational modules,and their detailed rules and supporting tools were determined,thus completing the construction of the entire practical pathway.Results:A complete set of clinical practice pathways for narrative medicine in TCM had been established.It encompassed six core modules,including"start of diagnosis and treatment","communication of disease conditions","diagnosis and explanation","joint decision-making","end of diagnosis and treatment",and"reflection and summary".Besides,detailed operating rules and supporting tools were also provided.Conclusion:The clinical practice pathway for narrative medicine in TCM integrates the humanistic spirit of TCM,the core concepts of narrative medicine,and the communication skills of psychology,providing medical workers with standardized,procedural,and operationally flexible practice guidance,which helps both doctors and patients to better communicate,empathize,and make joint decisions throughout the entire process of diagnosis and treatment.

In recent years， the incidence of colorectal cancer has been rising in China， and with the promotion of early screening and early diagnosis， most colorectal cancers are able to achieve long-term survival through timely diagnosis and treatment. Nevertheless， 30%-70% of patients with early to mid-stage colorectal cancer after radical surgery still have psychological problems such as anxiety， depression， and fear of recurrence and metastasis， and they hope to seek help from traditional Chinese medicine（TCM） treatment. In order to further standardize the integrated traditional Chinese and western medicine psychological rehabilitation interventions of stage Ⅰ-Ⅲ colorectal cancer after radical surgery， and to improve the diagnosis and treatment level， under the support of the pilot project of clinical collaboration between Chinese and western medicine for major and difficult diseases of National Administration of TCM， experts in oncology， integrated Chinese and western medicine， psychology， surgery， nursing， evidence-based medicine and other disciplines from 10 units nationwide participated in the work， led by Xiyuan Hospital，China Academy of Chinese Medical Sciences and Beijing Cancer Hospital. Based on the methodology and process of guideline development of the World Health Organization Handbook for Guideline Development and the Regulations for Group Standards of China Association of Chinese Medicine， the Guidelines for Psychological Rehabilitation Intervention Combined Integrated Traditional Chinese and Western Medicine After Radical Surgery for Early and Middle Stage Colorectal Cancer have been developed according to the current best evidence， extensive consultation with clinical experts and following the situation of current clinical practice. The guideline provides the psychological characteristics， the needs and willingness to accept psychological rehabilitation， the interventions for psychological rehabilitation， evaluation of efficacy， follow-up review， educational guidance and others of patients with stage Ⅰ-Ⅲ colorectal cancer after radical surgery. It can provide guidance for TCM（integrated Chinese and western medicine） clinicians and psychologists engaged in the psychological rehabilitation of integrated Chinese and western medicine oncology， especially for doctors in primary medical institutions.

Objective:To study the clinical efficacy of surgical resection combined with iodine-131 ( 131I) therapy in elderly patients with differentiated thyroid cancer and its influence on complications. Methods:Totally 82 elderly patients with differentiated thyroid cancer who were admitted to Chengde Central Hospital from March 2019 to March 2021 were selected and divided into observation group (41 cases) and control group (41 cases) according to the random number table. The control group underwent total thyroidectomy + neck lymph node dissection, and the observation group was treated with 131I after the operation on the basis of the control group. The indicators in the two groups were evaluated (postoperative observation time cutoff was 3 months), including perioperative indexes, postoperative complications, Karnofsky (KPS) score, serum levels of lymphocyte activating gene-3 (LAG-3) and recombinant human Dick-kopfx related protein-1 (DKK-1) before and after treatment, and the efficacy. Results:There was no significant difference between the two groups in the amount of intraoperative bleeding and operation time ( P > 0.05); the hospitalization time in the observation group [(6.72 ± 1.39) d] was shorter than that in the control group [(8.78 ± 1.43) d, P < 0.001]. The incidence of complications in the observation group (31.71%, 13/41) was lower than that in the control group (53.66%, 22/41, P = 0.045). After treatment, KPS scores in the two groups were higher than those before treatment ( P < 0.001); after treatment, KPS score in the observation group was higher than that in the control group ( P < 0.001). After treatment, the serum LAG-3 levels in the two groups were higher than those before treatment, while DKK-1 levels were lower than those before treatment ( P < 0.001); after treatment, the serum LAG-3 level in the observation group was higher than that in the control group, while the DKK-1 level was lower than that in the control group ( P < 0.001). The total effective rate of the observation group (95.12%, 39/41) was higher than that of the control group (80.49%, 33/41, P = 0.043). Conclusion:The clinical efficacy of surgical resection combined with 131I therapy in elderly patients with differentiated thyroid cancer is good, and it can reduce postoperative complications, up-regulate the expression of LAG-3 and down-regulate the expression of DKK-1.

Traditional Chinese Medicine (TCM) products could be registered as natural health products (NHPs) in Canada. Its registration process could be mainly divided into simple-application, traditional-application and non-traditional application. By analyzingi the TCM registration evidence system and its safety, effectiveness and quality required by different registration categories in Canada, we found that "simple-application" procesure needs to submit evidence based on the parameters of a component in the monograph. As for "traditional application", TCM products need to be used at least 50 years with, traditional material or Pharmacopoeia can be used as evidence; As for non-traditional application, TCM products need to provide evidence according to the disease risk level, and most of them need to provide scientific experiment evidence. Therefore, from the experience of TCM registration evidence system in Canada, the registration of TCM products should pay attention to improve the its classification method, refining its evidence requirements and data types, promoting the formulation of monograph of TCM, realizing the scientific evaluation and rapid review of classic famous prescriptions, and promoting the inheritance and innovative development of TCM in China.

Cholelithiasis is a kind of common and multiple diseases.In recent years,traditional laparotomy has been challenged by a minimally invasive surgery.Through literature review,the therapeutic method,effect,and complications of minimally invasive treatment of intrahepatic and extrahepatic bile duct stones by combining our practical experience were summarized as follows.(1) For intrahepatic bile duct stones,the operation may be selected by laparoscopic liver resection,laparoscopic common bile duct exploration (LCBDE),or percutaneous transhepatic cholangioscopy.(2) For concomitant gallstones and common bile duct stones,the surgical approach can be selected as follows:laparoscopic cholecystectomy (LC) combined with endoscopic sphincterotomy (EST) or endoscopic papillary balloon dilatation,LC plus laparoscopic transcystic common bile duct exploration,LC plus LCBDE,and T-tube drainage or primary suture.(3) For concomitant intrahepatic and extrahepatic bile duct stones,laparoscopic liver resection,choledochoscopy through the hepatic duct orifice on the hepatectomy cross section,LCBDE,EST,and percutaneous transhepatic cholangioscopic lithotripsy could be used.According to the abovementioned principle,the minimally invasive treatment approach combined with the surgical technique and equipment condition will be significant in improving the therapeutic effect and avoiding the postoperative complications or hidden dangers of intrahepatic and extrahepatic bile duct stones.

Objective To investigate and analyze the antimicrobial unreasonable use of antibacterial drugs in the com-munity center and to explore the corresponding countermeasures according to the reasons in order to accumulate experi-ence for promoting the rational use of drugs. Methods A total of 27 community health centers in the city were randomly selected as the research object and 50 antibiotic prescriptions, randomly selected among the antibiotic prescriptions is-sued in every community health center in the year 2012, were checked. The unreasonable use of antibacterial drug was classified, summarized and analyzed in the audit process. The corresponding countermeasures were explored according to the causes of the irrational use of antibiotics and changes of the irrational use of antibiotics were compared before and after the implementation of countermeasures. Results 293 copies of antibiotic prescriptions among the 1350 copies of antibiotic prescriptions randomly selected in 2012 were found unreasonable after the review, which accounted for the entire21.7% of the prescribed doses. Among the 293 copies of antibiotic prescriptions, the unreasonable choice of an-tibacterial drug accounted for 13%, the irrational drug use combined with other drugs accounted for 20.8% and drugs repeatedly used accounted for 9.2%, unreasonable solvents accounted for 18.8% and the usage and amount of drugs, which were unreasonable, accounted for 38.2%. After the implementation of standard medication strategy in 2013, the rate of irrational drug use was significantly lower than that in 2012 (9.3% vs 21.7%,χ2=78.9,P<0.05). Conclusion Through the analysis of the statistics of irrational drug use in the community health center, the appropriate regulatory measures have been planed, which has laid the foundation for the choice of suitable antibiotics and adopt suitable medication method and has guaranteed the rationality and the scientific nature of clinical use of drugs.
