ObjectiveTo investigate the influence of triglyceride （TG）/high-density lipoprotein cholesterol （HDL-C） ratio on the onset of primary liver cancer. MethodsA prospective cohort study was conducted. Physical examination data were collected from 99 750 cases of on-the-job and retired employees of Kailuan Group who participated health examination from July 2006 to December 2007， and they were followed up till December 31， 2021 to observe the onset of primary liver cancer. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution between multiple groups； the chi-square test was used for comparison of categorical data between groups. According to the tertiles of TG/HDL-C ratio， the subjects were divided into Q1， Q2， and Q3 groups， and the incidence density of primary liver cancer was calculated for each group. The Kaplan-Meier method was used to calculate the cumulative incidence rate of primary liver cancer in each group， and the log-rank test was used to compare the difference in cumulative incidence rate between groups. The Cox proportional hazards model was used to analyze the influence of TG/HDL-C ratio on the onset of primary liver cancer. ResultsThere were significant differences between the three groups in age， proportion of male subjects， waist circumference， body mass index， fasting blood glucose， systolic pressure， diastolic pressure， triglyceride， total cholesterol， HDL-C， low-density lipoprotein cholesterol， alanine aminotransferase， high-sensitivity C-reactive protein， chronic liver diseases， hypertension， diabetes， the family history of malignant tumor， drinking， smoking， physical exercise， and educational level （P<0.05）. During the mean follow-up time of 14.06±2.71 years， there were 484 cases of new-onset liver cancer， among whom there were 446 male subjects and 38 female subjects. The incidence density of primary liver cancer was 0.39/1 000 person-years in the Q1 group， 0.35/1 000 person-years in the Q2 group， and 0.30/1 000 person-years in the Q3 group， and the cumulative incidence rates of primary liver cancer in the three groups were 6.03‰， 5.28‰， and 4.49‰， respectively， with a significant difference between the three groups based on the long-rank test （χ²=6.06， P=0.048）. After adjustment for the confounding factors considered， the Cox proportional hazards model showed that compared with the Q3 group， the Q1 group had a hazard ratio of 2.04 （95% confidence interval ［CI］： 1.61‍ ‍—‍ ‍2.58， P_{for trend}<0.05）， and the Q2 group had a hazard ratio of 1.53 （95%CI： 1.21‍ ‍—‍ ‍1.92， P_{for trend}<0.05）. ConclusionThe reduction in TG/HDL-C ratio is associated with an increase in the rask of primary liver cancer， especially in people with chronic liver diseases.

Objective:To conduct a series case study on hospitalized anthrax cases in five hospitals in North China, to share clinical experiences in the diagnosis and treatment of cutaneous and pulmonary anthrax.Methods:A retrospective, multicenter cohort study was conducted on the anthrax patients admitted to five hospitals in North China from August 2018 to March 2022. Forty patients were divided into severe and mild groups. The clinical features, treatment and prognosis of the patients were collected and analysed. Statistical evaluations included independent sample t test, Mann-Whitney U test, and chi-square test. Results:Among the 40 patients with anthrax, 10(25.0%) were severely ill and 30(75.0%) were mildly ill. According to the sites of infection, 40 patients were classified as 39 cutaneous anthrax cases (one case had secondary pulmonary anthrax) and one pulmonary anthrax case. The rates of chills and fever, lymphadenopathy, liver dysfunction and hypoalbuminemia in the severe group were all higher than those in the mild group, with statistically significant differences ( χ2=5.71, 6.54, 4.68 and 9.22, respectively, all P<0.05). The peripheral white blood cell count, neutrophil count, neutrophil/lymphocyte ratio and C-reactive protein were (11.8±4.9)×10 9/L, (9.5±5.1)×10 9/L, 8.6±7.3, 27.9(8.6, 167.7) mg/L, respectively, which were all higher than those in mild disease group ((7.5±2.4)×10 9/L, (5.0±2.1)×10 9/L, 3.2±2.3, 3.5(1.2, 14.7) mg/L), with statistically significant differences ( t=2.66, t=2.71, t=2.32 and Z=-3.01, respectively, all P<0.05). The albumin level in the severe group was (35.5±8.1) g/L, which was lower than that of the mild group ((43.7±3.2) g/L), and the difference was statistically significant ( t=-3.13, P=0.011). The severe cases were more likely to have skin lesions greater than four centimetre in diameter, multiple, vesicular, or edematous, with a significant difference ( χ2=6.01, P=0.014). Among 39 patients with cutaneous anthrax, 28(71.8%) in the mild group were treated with penicillin alone, and nine (23.1%) in the severe group were treated with penicillin, ofloxacin, piperacillin/tazobactam combined with one of linezolid, doxycycline, or clindamycin for anti-infection treatment. The two patients with pulmonary anthrax were treated with closed thoracic drainage for pleural effusion and pneumothorax, and were treated with two bactericidal and one protein synthesis inhibitor antibiotics. All 40 anthrax patients were cured and discharged from hospital. Conclusions:Patients with mild cutaneous anthrax can generally be treated with single penicillin, and patients with severe cutaneous anthrax and pulmonary anthrax should be treated with combined antibiotics.

Objective:To discuss the relationship between 18F-FDG PET/CT metabolic parameters and clinical pathological indicators and prognosis in cutaneous malignant melanoma (CMM). Methods:A total of 100 CMM patients (62 males, 38 females, age (56.5±2.5) years) who underwent 18F-FDG PET/CT scans at the Second Xiangya Hospital of Central South University from August 2013 to November 2022 were retrospectively enrolled. Clinical pathological indicators (such as primary site, TNM staging, sentinel lymph node (SLN) status) and metabolic parameters (SUV max, metabolic tumor volume (MTV), total lesion glycolysis (TLG), whole-body MTV (wb-MTV), and whole-body TLG (wb-TLG)) were collected. ROC curve analyses were used to determine the PET parameters thresholds for progression-free survival (PFS) and melanoma-specific survival (MSS). Kaplan-Meier survival analysis, univariate and multivariate Cox proportional hazards regression models were used to analyze the prognosis of patients′ PFS and MSS, and a nomogram survival prediction model was constructed. Results:Results of ROC curve analyses showed that the thresholds of SUV max of primary tumor (p-SUV max), MTV of primary tumor (p-MTV), TLG of primary tumor (p-TLG), wb-MTV and wb-TLG for predicting PFS and MSS were 7.13, 2.24 cm 3, 6.98 g, 2.57 cm 3, 8.04 g and 9.09, 2.34 cm 3, 7.44 g, 2.24 cm 3, 9.17 g, respectively. Results of univariate analysis indicated that several clinical pathological indicators and metabolic parameters were prognostic risk factors for PFS and MSS. Results of multivariate analysis indicated that metastases of SLN (hazard ratio( HR)=2.54, 95% CI: 1.09-5.90; P=0.030) and wb-TLG>8.04 g( HR=2.58, 95% CI: 1.17-5.72; P=0.019) were independent prognostic risk factors for PFS, while metastases of SLN ( HR=4.53, 95% CI: 1.54-13.35; P=0.006) and wb-TLG>9.17 g ( HR=2.48, 95% CI: 1.26-4.89; P=0.009) were independent risk prognostic factors for MSS. A nomogram survival prediction model based on PET metabolic parameter (wb-TLG) and clinical pathological indicator (SLN status) can effectively predict the prognosis of CMM patients. Conclusions:Clinical pathological parameters and PET parameters are associated with the prognosis of CMM patients. SLN status is critical for prognosis.

Objective:To investigate the association of total sleep time (TST) and oxygen desaturation index (ODI) with hypertension in patients with obstructive sleep apnea/hypopnea syndrome (OSA).Methods:A total of 440 OSA patients admitted to Yixing Hospital from January 2017 to December 2022 were consecutively enrolled, including 236 patients with hypertension (OSA+hypertension group) and 204 patients without hypertension (OSA group). The clinical data and polysomnograpic parameters were collected. Univariate and multivariate logistic regression was used to analyze the related factors of OSA complicated with hypertension. The multiplicative interaction between TST and ODI on OSA with hypertension was analyzed. A two-factor cross-over analysis of TST and ODI was performed and the additive interaction model was used to analyze the additive interaction between TST and ODI on OSA with hypertension.Results:Univariate logistic regression showed that male sex, smoking, diabetes, coronary heart disease, TST <7 h, age, body mass index, neck circumference, waist circumference, Epworth Sleepiness Scale (ESS) score, TST, AHI, ODI>16 times/h, triglyceride, high density lipoprotein cholesterol and fasting blood glucose were positively correlated with hypertension in OSA patients (all P<0.05). Multivariate logistic regression analysis showed that smoking ( OR=4.327, 95% CI: 2.499-2.499, P<0.001), TST<7 h ( OR=1.748, 95% CI: 1.079-2.832, P=0.023) and ODI>16 times/h ( OR=3.482, 95% CI: 2.016-6.014, P<0.001) were independently associated with hypertension in OSA patients. After introducing a multiplicative term and adjusting for confounding factors, there was a positive multiplication interaction between TST <7 h and ODI>16 times/h ( OR=2.958, 95% CI: 1.079-8.113, P<0.050). Multivariate logistic regression analysis showed that the risk of hypertension in OSA patients with TST<7 h and ODI>16 times/h was 7.196 times (95% CI: 3.421-15.137) higher than that in patients with TST≥7 h and ODI≤16 times/h. The additive interaction model showed a synergistic effect between TST<7 h and ODI>16 times/h, with S value of 4.302 (95% CI: 1.566-11.815), RERI value of 4.756 (95% CI: 0.642-8.869) and API value of 66.10% (95% CI: 43.10%-89.10%). Conclusion:Shortened sleep duration and increased ODI are independent risk factors for hypertension in OSA patients, and when they coexist, the risk of hypertension in OSA patients is further increased.

OBJECTIVE To understand the current status of research on traditional Chinese medicine（TCM） human resources， and to provide a reference for expanding research ideas on TCM human resources and promoting the construction of TCM talents. METHODS From January 1， 2000 to December 31， 2022， literature related to TCM human resources was collected from the three major databases of CNKI， Wanfang and VIP. Using CiteSpace 5.8 R3 software， visualization analysis was performed for the literature in terms of publication time， journal sources， authors， institutions and areas， funding， research content， keywords， etc. RESULTS A total of 324 literature related to TCM human resources in China were included， and the number of literature issued showed an upward trend， with an annual average of 14.09 literature； 161 kinds of journals were involved， core journals accounted for 18.21% of the total publication volume； a total of 23 authors had published 2 or more literature， with a total of 55 literature published （16.98%）； a total of 416 institutions were involved， mainly schools （66.83%）； 60.49% of the literature were supported by the fund. The majorities of 324 literature were survey studies （170 literature）， and most of them used self-designed questionnaires （55 literature）； the high-frequency keywords included talent training， human resources， TCM， etc. The keywords were clustered into 7 categories， such as “human resources“”talent training“”TCM industry“”TCM services“”talent training models” “fairness” and “TCM talents”. The main problems described in the literature included insufficient talent， lack of reasonable distribution of regional structure， lack of reasonable plans for talent training， and insufficient professional knowledge and abilities. Continuously cultivating high-level talents and improving employment conditions in areas with severe human resource loss were the corresponding countermeasures proposed in the literature. CONCLUSIONS The research on TCM human resources starts late but has developed rapidly overall， and the quality of research needs to be improved； the structure of research team is single and unevenly distributed geographically； there is a structural imbalance in the allocation of human resources， as well as problems such as a shortage of professional talents， low levels of education and training and incomplete development systems.

OBJECTIVES: This study examined the associations between adverse childhood experiences (ACEs) and diabetes within a social-ecological framework, incorporating personal and environmental unfavorable conditions during childhood from family, school, and community contexts. METHODS: Data were obtained from the China Health and Retirement Longitudinal Study (2014 life history survey and 2015 survey), including 9,179 participants aged ≥45 years. ACEs were collected through self-report questionnaires, and participants were categorized based on the number of distinct ACEs experienced (0, 1, 2, 3, or ≥4 ACEs). Diabetes was defined by biomarkers, self-reported diagnosis, and treatment status. Logistic regression was conducted to explore the associations between ACEs and diabetes. Subgroup analyses were conducted by gender, age, and obesity status. RESULTS: Compared with participants without ACEs, those exposed to any ACE (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.01 to 1.40), 3 ACEs (OR, 1.32; 95% CI, 1.07 to 1.62) and ≥4 ACEs (OR, 1.29; 95% CI, 1.07 to 1.56) had an increased risk of diabetes. For each additional ACE, the risk of diabetes increased by about 5%. Regarding the source of ACEs, those originating from the family (OR, 1.23; 95% CI, 1.08 to 1.41) were associated with diabetes. In terms of specific ACE types, family members with substance abuse (OR, 1.23; 95% CI, 1.01 to 1.52), emotional abuse (OR, 1.28; 95% CI, 1.12 to 1.46), and poor parental relationship (OR, 1.25; 95% CI, 1.09 to 1.43) were associated with diabetes. CONCLUSIONS ACEs, particularly those originating from the family, were associated with diabetes. Interventions aimed at preventing and mitigating ACEs are essential for the early prevention of diabetes.

Objective To explore the humidification effects between the humidifiers Venturi high-flow oxygen therapy(HVHF)and the high-flow humidified oxygen therapy in the treatment of patients with tracheotomy after the withdrawal of ventilator,and analyse the humidification performance and effect of airway humidification on the two oxygen therapies hence to provide an objective basis for selection of a humidified oxygen therapy.Methods A total of 146 ICU patients who had tracheotomy and completely withdrawal of ventilator in a general hospital in Shenzhen from July 2020 to December 2021 were randomly divided into trial group(n=73)and control group(n=73).With identical speed of airflow,patients in the trial groups were treated with HVHF and the patients of control group were offered with high-flow humidified oxygen therapy via AIRVOTM2.Data of the two groups were compared at the time points of days 0,2,7 and 14 in terms of absolute humidity(AH),relative humidity(RH),temperature(T)),sputum viscosity,arterial partial pressure of oxygen(PaO2),arterial partial pressure of carbon dioxide(PaCO2),oxygenation index(PaO2/FIO2)and the incidence of pulmonary infection.Results In the study,total of 61 patients in the control group and 72 patients in the trial group completed the high-flow humidified oxygen therapies,due to tubing detachments in 12 and 1 patients in the two groups,respectively.Repeated-Measures ANOVA analysis showed that,in both groups,there was a time effect(P<0.05)between the absolute humidity,relative humidity,temperature of the gas,PaO2,PaCO2,and PaO2/FiO2 at different time points.PaO2 and PaO2/FiO2 in both groups showed interactions at different time points(P<0.05).PaO2 and PaO2/FiO2 in the trial group were better than those in the control group at the time points of days 2,7 and 14(P<0.05).On days 2,7 and 14,the viscosity of sputum in the intervention group was better than that in the control group,and the incidence of pulmonary infection in the trial group was significantly lower than that in the control group(P<0.05).Conclusions HVHF and AIRVOTM2 both exhibit no obvious difference in gas humidification via high-flow humidification oxygen therapy in the patients with tracheotomy after withdrawal of ventilator.However,HVHF is superior to AIRVOTM2 in terms of improving airway humidification and oxygenation as well as reducing lung infection.Therefore,it is suggested that an HVHF is preferable for high-flow humidified oxygen therapy in treating the patients with tracheotomy after the withdrawal of ventilator.

Objective:To investigate the effect of 18F-FDG combined with 18F-prostate specific membrane antigen (PSMA)-1007 PET/CT on TNM staging and clinical treatment decision of patients with prostate cancer. Methods:Clinical data and PET/CT images of 31 patients (age (69.9±9.2) years) with prostate cancer who underwent PET/CT imaging with 18F-FDG and 18F-PSMA-1007 (dual-tracer imaging) in the Second Xiangya Hospital of Central South University from June 2020 to March 2022 were retrospectively analyzed. Paired χ2 test was used to compare the diagnostic efficacy of 18F-FDG, 18F-PSMA-1007 and combined imaging for diagnosing primary prostate cancer, regional lymph node metastases and distant metastases, and to analyze the influence of combined imaging on clinical treatment decision. Results:There were 282 metastatic sites in 31 patients, including 46 regional lymph node metastases in 13 patients and 236 distant metastases in 15 patients. The detection rates of 18F-PSMA-1007 PET/CT and combined imaging for primary lesions were higher than the detection rate of 18F-FDG PET/CT (100%(31/31), 100%(31/31) vs 64.5%(20/31); χ2=13.37, P<0.001). Based on analysis of patients, the detection rates of 18F-PSMA-1007 PET/CT and combined imaging for regional lymph node metastases were higher than the detection rate of 18F-FDG PET/CT (12/13, 12/13 vs 6/13; χ2=4.51, P=0.034), and the 3 detection rates for distant metastases were also significantly different (15/15, 15/15 vs 10/15; χ2=6.00, P=0.042). Based on analysis of lesions, the detection rates of 18F-PSMA-1007 PET/CT and combined imaging for regional lymph node metastases were higher than the detection rate of 18F-FDG PET/CT (95.7%(44/46), 97.8%(45/46) and 45.7%(21/46); χ2 values: 25.37-49.56, all P<0.001). The detection rate of combined imaging for distant metastases was higher than that of 18F-FDG or 18F-PSMA-1007 PET/CT alone (96.2%(227/236) vs 68.6%(162/236), 58.9%(139/236)); and the detection rate of 18F-FDG PET/CT was higher than that of 18F-PSMA-1007 PET/CT ( χ2 values: 4.85-94.22, all P<0.05). Clinical treatment decisions in 10 patients (32.3%, 10/31) were changed based on the results of combined imaging. Conclusion:For prostate cancer with suspected distant metastases, 18F-FDG and 18F-PSMA-1007 dual-tracer PET/CT imaging can improve staging and guide clinical treatment decisions.

Objective To understand the activity concentrations of natural radionuclides ⁴⁰K, ²²⁶Ra, ²³²Th, and ²³⁸U in raw coal of coal mines in some regions of China, and to explore the correlation between ore with different activity concentrations and the concentration of radon and its progeny in the workplace. Methods Raw coal samples were collected in twelve coal mines in five provinces, and the activity concentrations of ⁴⁰K, ²²⁶Ra, ²³²Th, and ²³⁸U were measured by a high-purity germanium γ-ray spectrometric system. Results The activity concentrations of four natural radionuclides in the raw coal samples of twelve coal mines were all lower than 1000 Bq/kg, and the activity concentration of ²³⁸U in one coal mine was close to 100 Bq/kg. The content of ⁴⁰K, ²²⁶Ra, ²³²Th, and ²³⁸U in different coal mines varied greatly, but ²²⁶Ra, ²³²Th, and ²³⁸U were basically at the same level in the same coal mine. Conclusion None of the 12 coal mines belong to radio active mines. One of the coal mines investigated has the activity concentrations of ²²⁶Ra, ²³²Th, and ²³⁸U close to the standard limit for restricted-use management mines. It is suggested to study the correlation between the content of ²²⁶Ra in raw ore, intermediate products, tailings(slag), or other residues and the concentration of radon and its progeny in mines. Monitoring and protection of radon and its progeny in the decay chain should be strengthened for coal mines with high activity concentrations of natural radionuclides ²²⁶Ra, ²³²Th, and ²³⁸U.
