Objective To analyze the epidemiological characteristics of lung cancer death in Gansu Province, and to provide a theoretical basis for formulating the prevention and control measures of lung cancer. Methods The lung cancer death data from national monitoring sites in Gansu Province from 2014 to 2023 were selected. Excel2013 and SPSS17.0 were used to calculate lung cancer mortality, standardized mortality, potential years of life lost (PYLL), potential years of life lost rate, standardized potential years of life lost rate, and average years of life lost (AYLL). The annual percent change (APC) of the crude lung cancer mortality rate and standardized mortality rate was calculated using Joinpiont 4.8.0.1 software. The mortality difference decomposition method was used to analyze demographic and non-demographic factors. Results From 2014 to 2023, the crude mortality rate of lung cancer among the residents of the monitoring sites in Gansu Province showed an increasing trend. The mortality rate of males was higher than that of females. The mortality rate in urban areas was higher than that in rural areas. The population structure was the main factor leading to the increase of lung cancer mortality rate in urban areas, while other non-demographic factors were the main factors leading to the increase of lung cancer mortality rate in rural areas. The crude lung cancer mortality rate was low at the age of < 30, and then the mortality rate increased with age. Lung cancer PYLL was higher in males than in females, and AYLL was higher in females than in males. Conclusion The mortality rate of lung cancer in the monitoring sites in Gansu Province is on the rise. The urban areas and male population are the key areas and groups for intervention. It is suggested to further strengthen the early screening and intervention of lung cancer to reduce the mortality rate of lung cancer.

Objective To investigate the effects of sugammadex on postoperative pulmonary com-plications(PPCs)and postoperative recovery after thoracoscopic lung resection surgery.Methods A total of 263 patients scheduled for thoracoscopic lung resection surgery between November 2021 and July 2023,112 males and 151 females,aged 18-64 years,BMI 18.5-28.0 kg/m2,ASA physical status Ⅰ-Ⅲ,were randomly divided into three groups:the sugammadex group(group S,n=88),the neostigmine group(group N,n=87),and the control group(group C,n=88).The patient was sent to postanesthesia care unit(PACU)after operation,when the train of four(TOF)count reached 2,group S was given sugamma-dex 2 mg/kg,group N was given neostigmine 0.04 mg/kg+atropine 0.02 mg/kg,and group C was given equal volume of normal saline.The incidence of PPCs from the end of the surgery to the time of discharge was recorded.The time from the end of surgery to extubation,the time from drug administration to recovery of the train of four ratio(TOFr)to 0.9,the TOFr immediately after extubation,the length of stay in PACU,hypoxemia after extubation(SpO2＜90％)were recorded,and the incidence rate of postoperative residual neuromuscular block(PRNB)was calculated.The time of first getting out of the bed for activity,the number of total and effective compressions by the analgesia pump within 48 hours after surgery,the inci-dence of rescue analgesia,the clinical pulmonary infection score(CPIS),the numbers of postoperative nau-sea and vomiting(PONV),total drainage of the chest tube,duration of the chest tube insertion,and the length of postoperative hospital stay were recorded.Results Compared with group C,the incidence of PPCs,PRNB and hypoxemia after extubation were significantly decreased,time from the end of surgery to extubation,time from drug administration to recovery of TOFr to 0.9,the length of stay in PACU,and the first postoperatively out of bed activity time were significantly shortened,the TOFr immediately after extuba-tion was significantly increased,and CPIS was significantly decreased in group S(P＜0.05);the time from the end of surgery to extubation,time from drug administration to recovery of TOFr to 0.9,the length of stay in PACU were significantly shortened,the TOFr immediately after extubation was significantly in-creased,PRNB after extubation were significantly decreased in group N(P＜0.05).Compared with group N,the incidence of PRNB after extubation were significantly decreased,the time from the end of surgery to extubation,the time from drug administration to recovery of TOFr to 0.9,the length of stay in PACU,and the first postoperatively out of bed activity time were significantly shortened,the TOFr immediately after ex-tubation was significantly increased in group S(P＜0.05).There was no significant difference in other in-dexes between the three groups.Conclusion Sugammadex can rapidly antagonize the residual muscle re-laxation,decrease the rate of PPCs and PRNB,and promote rapid recovery of patients after thoracoscopic lung resection surgery.

Objective To investigate the relationship between aspartate aminotransferase-platelet ratio index(APRI)and hepatocellular carcinoma(HCC)recurrence after radiofrequency ablation(RFA),and to construct a nomogram model for predicting the prognosis.Methods The clinical data of a total of 204 patients,whose initial diagnosis was HCC and received RFA at the Wujin Hospital Affiliated to Jiangsu University of China between January 2017 and December 2020,were retrospectively analyzed.The optimal cut-off value of APRI was determined using receiver operating characteristic(ROC)curve.Kaplan-Meier curves were plotted to estimate the recurrence-free survival(RFS)of high-APRI group patients and low-APRI group patients.The independent predictors of HCC recurrence after RFA were identified by using univariate and multivariate Cox regression analysis,and significant variables were selected to construct a nomogram model.The predictive ability of the nomogram model for HCC recurrence was evaluated by the consistency index(C-index)and calibration curves.Results The incidence of HCC recurrence after RFA was 57.4%(117/204),the optimal cut-off value of APRI for predicting HCC recurrence was 0.501,and the area under curve(AUC)value was 0.678(95%CI=0.603-0.752).High-APRI group(≥0.501)had 121 patients and low-APRI group(＜0.501)had 83 patients.High APRI index was significantly correlated with low RFS(χ2=12.929,P＜0.01).The univariate and multivariate Cox regression analysis revealed that the number of tumors(HR=1.541,95%CI=1.039-2.286,P=0.031),maximum tumor diameter(HR=1.461,95%CI=1.011-2.112,P=0.044),serum AFP level(HR=2.286,95%CI=1.576-3.318,P＜0.01)and APRI index(HR=1.873,95%CI=1.257-2.790,P=0.002)were the independent risk factors for HCC recurrence.Based on the above four variables,a nomogram model for predicting HCC recurrence after RFA was constructed,the C-index was 0.769(95%CI=0.676-0.862),and the AUC values for 1-,2-,and 3-year RFS prediction were 0.707,0.719,and 0.707,respectively.The calibration curves showed that a good consistency existed between the predicted probability and actual probability.Conclusion The nomogram model based on APRI and tumor biological characteristics has an excellent predictive ability for HCC recurrence after RFA.(J Intervent Radiol,2024,32:38-43)

BACKGROUND: The prevalence of hypertension is high among Chinese adults, thus, identifying non-hypertensive individuals at high risk for intervention will help to improve the efficiency of primary prevention strategies. METHODS: The cross-sectional data on 9699 participants aged 20 to 80 years were collected from the China National Health Survey in Gansu and Hebei provinces in 2016 to 2017, and they were nonrandomly split into the training set and validation set based on location. Multivariable logistic regression analysis was performed to develop the diagnostic prediction model, which was presented as a nomogram and a website with risk classification. Predictive performances of the model were evaluated using discrimination and calibration, and were further compared with a previously published model. Decision curve analysis was used to calculate the standardized net benefit for assessing the clinical usefulness of the model. RESULTS: The Lasso regression analysis identified the significant predictors of hypertension in the training set, and a diagnostic model was developed using logistic regression. A nomogram with risk classification was constructed to visualize the model, and a website ( https://chris-yu.shinyapps.io/hypertension_risk_prediction/ ) was developed to calculate the exact probabilities of hypertension. The model showed good discrimination and calibration, with the C-index of 0.789 (95% confidence interval [CI]: 0.768, 0.810) through internal validation and 0.829 (95% CI: 0.816, 0.842) through external validation. Decision curve analysis demonstrated that the model was clinically useful. The model had a higher area under receiver operating characteristic curves in training and validation sets compared with a previously published diagnostic model based on Northern China population. CONCLUSION This study developed and validated a diagnostic model for hypertension prediction in Gansu Province. A nomogram and a website were developed to make the model conveniently used to facilitate the individualized prediction of hypertension in the general population of Han and Yugur.

Objective:To investigate the pathogenesis of Cushing′s syndrome induced by medullary thyroid carcinoma.Methods:Started from April 2011 to present, three medullary thyroid carcinoma patients with Cushing′s syndrome were enrolled in this study. All patients were 40 to 50 years old, one female and two males. The blood pressure, blood glucose, thyroid function and antibodies, calcitonin, and carcinoembryonic antigen(CEA)were detected. The qualitative and localized diagnosis of Cushing′s syndrome was performed by high- and low-dose dexamethasone suppression tests as well as imaging examinations. The biopsies of all patients were taken to test the immunostaining of calcitonin, adrenocorticotropin(ACTH), and corticotropin-releasing hormone(CRH).Results:According to the clinical manifestation and function tests, three patients were diagnosed as medullary thyroid carcinoma accompanied by ACTH-dependent Cushing′s syndrome. All patients showed positive immunohistochemical staining of calcitonin and CRH, with negative immunostaining of ACTH in one and positive immunostaining of ACTH in two patients. Therefore, the diagnosis of ectopic CRH syndrome caused by medullary thyroid carcinoma was definite.Conclusions:Medullary thyroid carcinoma is a rare cause of Cushing′s syndrome. Tumor cells secrete ACTH and CRH, which in turn cause hypercorticoremia. Ectopic CRH syndrome is very rare. Early diagnosis can be made by immunohistochemical staining of biopsy tissues to guide early targeted treatment and improve the prognosis.

Objective:To investigate the clinical application of carbon nanoparticles mapping lymph nodes in curative resection for colorectal carcinoma.Methods:Patients diagnosed with colorectal cancer before operation and undergoing radical surgery with intact postoperative pathological data in the Sixth Affiliated Hospital, Sun Yat-sen University from March 2016 to March 2018 were included in this retrospective case-control study. Those who were diagnosed with ileus, recurrent carcinoma or underwent emergency operation were excluded. A total of 1421 cases were included, with 156 cases in the carbon nanoparticles mapping group and 1265 cases in the control group. Using 1∶3 case control matching based on gender, weight, TNM staging and neoadjuvant chemotherapy, 145 and 435 cases were finally recruited in the carbon nanoparticles mapping group and control group, respectively. Patients in the carbon nanoparticles mapping group underwent preoperative colonoscopy with carbon nanoparticles submucosal injection 2.4 (1.0 - 14.0) days before operation. Carbon nanoparticles of 0.25 ml was injected at 4 points (3, 6, 9 and 12 o'clock each) 0.5-1.0 cm around the tumor. The number of eliminated lymph node, number of positive lymph node and positive rate between the two groups were compared, and the number of eliminated lymph node in different subgroups of T stage, N stage, TNM stage and neoadjuvant chemotherapy was analyzed and compared.Results:After case control matching, total number of eliminated lymph nodes in the carbon nanoparticles mapping group was significantly higher than that in the control group (22.2±11.2 vs. 19.0±9.5, t=3.025, P=0.003). However, no statistically significant differences were found in the number of positive lymph node and lymph node positive rate between two groups (all P>0.05). Subgroup analysis showed that as compared to the control group, total number of eliminated lymph nodes in the carbon nanoparticles mapping group was significantly higher in T3 stage subgroup (median: 22 vs. 18, Z=2.435, P=0.015), N0 stage subgroup (median: 20.5 vs. 17.5, Z=2.772, P=0.006), TNM II stage subgroup (median: 23.5 vs. 19.0, Z=2.654, P=0.008) and neoadjuvant chemotherapy (median: 22.5 vs. 13.0, Z=3.287, P=0.001), while compared to the control group, the number of positive lymph node (median: 4.0 vs. 6.5, Z=-2.530, P=0.011) and the lymph node metastasis degree (median: 16% vs. 31%, Z=-2.862, P=0.004) were lower in the carbon nanoparticles mapping group in N2 subgroup. Conclusion:Carbon nanoparticles mapping lymph nodes can effectively enhance the number of eliminated lymph nodes in curative resection for colorectal cancer.

Objective:To understand the present situation of occupational benefit and job satisfaction of nurses in Guangzhou medical and nursing institutions, and to analyze the influencing factors of occupational benefit, so as to provide reference for the managers of pension institutions to formulate measures.Methods:A total of 83 in-service nurses from four medical and nursing institutions in Guangzhou were selected by convenient sampling. The general data questionnaire, nurses′ occupational benefit scale, job satisfaction scale, organizational support scale and job input scale were used to adjust the questionnaire.Results:The total score of occupational benefit of nurses in Guangzhou medical and nursing institutions was 106.14±16.38, which was in the middle level. Among them, the score of good nurse-patient relationship (76.40%) was the highest, the score of positive occupational perception(69.20%) was the lowest, and the total score of job satisfaction was 95.25±14.06. Among them, the score of satisfaction with colleagues (76.87%) was the highest, and the score of welfare treatment and professional development opportunity (55.40%, 56.15%) was lower. The total scores of organizational support and work input were 40.18 ± 9.58 and 54.92 ± 9.58, respectively. The results of multiple linear regression showed that nurses′ age, job satisfaction, organizational support and job input were the important factors affecting nurses′ sense of professional benefit( t values were -3.518-6.668, P<0.01 or 0.05). Conclusions:The managers of pension institutions should take positive measures to improve the welfare treatment of nurses, increase their professional development opportunities, strengthen emotional support for nurses, improve nurses′ concentration and energy input to work, so as to improve nurses′ sense of professional benefit and job satisfaction.

OBJECTIVE： To investigate inhibitory effects of protopine on the proliferation of human hepatic stellate cells HSC-LX2 and to explore its mechanism preliminarily. METHODS： MTT assay was used to detect the effects of 25， 50， 100， 200， 400 and 500 μmol/L protopine on the proliferation of HSC-LX2 cells. The inhibitory effect of cell proliferation was calculated. HSC-LX2 cells were divided into control group （1640 medium containing 5％ fetal bovine serum）， protopine low-concentration， medium-concentration and high-concentration groups （100， 200， 400 μmol/L）. After treated for 24 h. The apoptotic rate of the cells was detected by flow cytometry. RT-PCR was used to determine the mRNA expression of α-SMA， Collagen Ⅰ， Collagen Ⅲ， MMP-2 and TIMP-1 in cells. The protein expressions of α-SMA， Collagen Ⅰ， Collagen Ⅲ and MMP-2 were detected by Western blot. RESULTS： The inhibitory rates of 25， 50， 100， 200， 400 and 500 μmol/L protopine on proliferation HSC-LX2 cells were 0， 6.9％， 18.7％， 34.2％， 48.9％， 53.9％， respectively. Compared with control group， mRNA expression of Collagen Ⅰ， TIMP-1 and protein expression of α-SMA were decreased significantly in protopine low-concentration， medium-concentration and high-concentration groups， while protein expression of MMP- 2 was increased significantly， with statistical significance （P＜0.05 or P＜0.01）. Apoptotic rate of HSC-LX2 cells and mRNA expression of MMP-2 were increased significantly in protopine medium-concentration and high-concentration groups， mRNA expression of α-SMA and Collagen Ⅲ， protein expression of Collagen Ⅰ and Collagen Ⅲ were decreased significantly， with statistical significance （P＜0.05 or P＜0.01）. CONCLUSIONS： Protopine can induce the apoptosis of HSC-LX2 cells and inhibit their cell proliferation， and reduce the expression of a-SMA， Collagen Ⅰ， Collagen Ⅲ and TIMP-1， and increase the expression of MMP-2.
