Objective To analyze the expression level of ATP5A1 in gastric carcinoma and its influence on the prognosis of the patients and glucose metabolism in the tumor cells.Methods We retrospectively analyzed the data of 115 patients undergoing radical resection of gastric carcinoma in our hospital from February,2013 to November,2016.ATP5A1 expression in the surgical specimens were detected using immunohistochemistry,and the long-term prognosis of the patients with high(n=58)and low ATP5A1 expression(n=57)were analyzed.In gastric carcinoma MGC803 cells,the effects of lentivirus-mediated ATP5A1 knockdown or overexpression on glucose metabolism were investigated.We also observed the growth and glucose metabolism of xenografts derived from MGC803 cells with ATP5A1 knockdown or overexpression in nude mice.Results ATP5A1 was significantly overexpressed in gastric carcinoma tissues in close correlation with blood CEA and CA19-9 levels,pathological grade,T stage and N stage(P<0.05).ATP5A1 overexpression was an independent risk factor for a significantly lowered 5-year survival rate of patients with gastric carcinoma(P<0.05).ROC curve analysis demonstrated the predictive value of high ATP5A1 expression for the patients'prognosis(P<0.001).In MGC803 cells,ATP5A1 overexpression significantly up-regulated cellular glucose uptake and lactate production and increased the protein levels of HK2,PFK1,and LDHA(P<0.05),while ATP5A1 knockdown produced the opposite changes(P<0.05).In the tumor-bearing mice,overexpression of ATP5A1 increased glucose metabolism of the tumor cells and promoted tumor growth(P<0.05).Overexpression of ATP5A1 promoted the expressions of p-JNK and p-JUN in MGC803 cells(P<0.05),and the JNK inhibitor SP600125 significantly inhibited the enhancement of cellular glucose metabolism induced by ATP5A1 overexpression(P<0.05).Conclusion High ATP5A1 expression in gastric cancer is associated a poor long-term prognosis of the patients,and its effect is mediated at least partly by promoting glucose metabolism of the cells through the JNK/JUN pathway.

Objective:To analyze the monitoring results of human brucellosis prevention and control project in Gansu Province, in order to provide reference for the next revision of prevention and control plans.Methods:The data from the "China Disease Prevention and Control Information System" in Gansu Province from 2016 to 2022 and the annual data of human brucellosis cases reported by the active monitoring reports in various project counties (districts) were input into Excel 2016 software and a database was established. The epidemiological situation of brucellosis, the coverage of brucellosis prevention and control projects, the number of detected cases and health education were analyzed and compared by descriptive epidemiological method.Results:From 2016 to 2022, 70 to 82 out of 86 counties (districts) in Gansu Province were found to have human outbreaks of brucellosis, with brucellosis prevention and control projects covering 17 to 43 counties (districts). A total of 19 855 cases of human brucellosis were reported online in the province, with an average annual incidence of 11.07/100 000 and an annual incidence ranging from 6.03/100 000 to 20.89/100 000. There was a statistically significant difference in incidence among years (χ 2 = 5 264.84, P < 0.001). Through active monitoring, a total of 433 303 cases of brucellosis (tiger red plate agglutination test, RBT) were initially screened in project counties (districts) throughout the province, with 13 277 positive cases and a positive rate of 3.06% (13 277/433 303). Then the laboratory confirmed test (test-tube agglutination test, SAT) for brucellosis was carried out, with 9 967 positive cases and a positive rate of 2.30% (9 967/433 303). The infection rate of brucellosis in the population (SAT positive) was compared between different years, and the difference was statistically significant (χ 2 = 600.12, P < 0.001). In the project counties (districts), 7 481 confirmed cases of brucellosis were detected by active surveillance, and 15 794 cases were reported online, accounting for 47.37% (7 481/15 794) of the total number of cases reported online. The average awareness rate of brucellosis knowledge among medical personnel increased from 70.49% before training to 88.89% after training. The average awareness rate of brucellosis prevention and control knowledge among high-risk groups increased from 63.49% before health education to 89.05% after health education, and the behavior formation rate increased from 62.84% to 86.04%. Conclusions:From 2016 to 2022, the epidemic scope of human brucellosis in Gansu Province has been expanding year by year, and the coverage of prevention and control project is relatively small. The proportion of cases detected through active screening is relatively low. It is necessary to increase special funding investment, expand project coverage, strengthen high-risk group screening, education and behavioral intervention, and follow-up management of acute stage patient, so as to identify patients as early as possible and curb the upward trend of the epidemic.

Aim To explore the correlation between atherogenic index of plasma(AIP),triglyceride-glucose(TyG)index and their severity in patients with chronic coronary syndrome(CCS).Methods A total of 298 patients diagnosed with CCS by coronary angiography were retrospectively selected from Cardiology Department of the First Hospital of Lanzhou University,from May 2017 to May 2023.Clinical indexes were collected and Gensini scores were calculated based on the results of the coronary angiography,clinical data of different Gensini integral groups was compared.Linear regression was used to analyze factors that influence the elevation of Gensini scores,and receiver operator characteristic(ROC)curve was used to determine the predictive value of AIP and TyG index for the severity of coronary artery lesions in CCS.Results The research sample consisted mostly of males(77.9％)with a mean age of(61.9±8.0)years.The adjusted AIP(aAIP)and TyG index of high Gensini score group were higher than those of low Gensini score group and medium Gensini score group,and the differences were significant.Linear regression analysis revealed that total cholesterol(TC),high density lipoprotein cholesterol(HDLC),aAIP and TyG index were the factors influencing the ele-vated Gensini scores(all P＜0.05).Correlation analysis revealed that aAIP and TyG index were negatively correlated with left ventricular ejection fraction(LVEF),positively correlated with Gensini scores,and positively correlated with stent implantation and the number of stent implantation(all P＜0.05).The ROC curve results indicated that when the aAIP threshold was 1.924,the area under the ROC curve(AUC)for predicting Gensini score ≥41 points was 0.583(95％CI 0.525～0.640),with a sensitivity of 92.62％,a specificity of 25.50％,and Yoden index of 0.181.When the TyG in-dex threshold was 8.748,the AUC for predicting Gensini score ≥41 points was 0.768(95％CI 0.716～0.815),with a sensitivity of 77.18％,specificity of 67.11％,and Yoden index of 0.443.Conclusion The aAIP and TyG index were positively correlated with the severity of coronary artery disease in CCS patients.Both elevated levels can predict the severity of coronary lesions in CCS patients,but TyG index showed superior predictive ability compared with aAIP.

Objective:To learn about the epidemic dynamics and spatial epidemic characteristics of human brucellosis in Gansu Province.Methods:Data on human brucellosis in Gansu Province reported by China Disease Control and Prevention Information System from January 2016 to December 2020 were collected and analyzed by descriptive epidemiology and spatial clustering analysis.Results:A total of 10 025 cases of human brucellosis were reported in Gansu Province from 2016 to 2020, with a statistically significant difference in incidence rate between years (χ 2 = 242.86, P = 0.001). The incidence was the lowest in 2018 (6.03/100 000), and the highest in 2020 (11.39/100 000). The reported cases were concentrated in 45 - 55 years old, accounting for 34.52% (3 461/10 025); the male to female ratio was 2.91 ∶ 1.00 (7 458/2 567); farmers were the main occupation, accounting for 82.11% (8 232/10 025). Among the 86 counties (cities, districts) in Gansu Province, Yongchang County had the highest number of reported cases in 2020 (339 cases), and Sunan Yugur Autonomous County had the highest incidence in 2020 (190.89/100 000). Spatial autocorrelation analysis showed that there was significant spatial positive correlation between the incidence rate of human brucellosis in Gansu Province from 2016 to 2020 (global Moran's I > 0, Z > 1.96, P < 0.05), showing a spatial clustering distribution. The high-high clustering areas were concentrated in Yongchang County and Sunan Yugur Autonomous County. Conclusion:In Gansu Province, the main population of human brucellosis is middle-aged male farmers, and the incidence of brucellosis is spatially clustered.

Objective:To study the epidemiological characteristics of human brucellosis in high incidence areas of brucellosis in Gansu Province, and provide a guidance for precise prevention and control of brucellosis in the areas with high incidence of the disease.Methods:Using a retrospective research method, human brucellosis monitoring data from five high incidence counties of brucellosis in Gansu Province from 2018 to 2020, including Huan County (eastern), Guazhou County (western), Zhangjiachuan County (southern), Gaotai County (northern), and Jingtai County (central), were collected from monitoring database of the Central Transfer Payment Project. The epidemic characteristics of brucellosis in high incidence areas were described and analyzed.Results:From 2018 to 2020, there were a total of 787 laboratory confirmed cases of brucellosis in high incidence areas of brucellosis in Gansu Province, with a prevalence rate of 3.64%. The incidence rates for each year were 2.63% (205/7 780), 4.60% (327/7 111), and 3.78% (255/6 746), with statistically significant differences between different years (χ 2 = 41.44, P < 0.001). The prevalence rates of brucellosis in Huan County, Guazhou County, Zhangjiachuan County, Gaotai County, and Jingtai County were 0.02% (1/4 263), 3.67% (140/3 817), 4.32% (182/4 209), 4.89% (237/4 847), and 5.04% (227/4 501), respectively. There was a statistically significant difference in comparison between different regions (χ 2 = 211.59, P < 0.001). In 2018, the incidence rate was highest in Jingtai County in the central region, and scattered to Zhangjiachuan County in the south and Gaotai County in the north in 2019 and 2020. There were statistically significant differences in the prevalence rates among different genders, ages, ethnicities, educational levels, and occupational groups (χ 2 = 111.95, 212.76, 35.32, 89.59, 97.93, P < 0.001). From 2018 to 2020, the incidence of brucellosis in the < 20 (0.78%, 6.36%, 10.00%), 40 - 50 age groups (5.15%, 7.03%, 8.00%), students and young children (0.58%, 9.20%, 13.64%), and cadres (2.86%, 4.55%, 10.53%) showed an increasing trend year by year (χ 2trend = 21.55, 7.00, 30.63, 2.01, P < 0.001). Conclusions:The brucellosis in Gansu Province is still in a high level of growth stage, and the epidemic area is gradually dispersing; the cases are gradually becoming younger, and key occupational personnel are shifting from farmers and herdsmen to social workers. It is recommended to increase the scope of monitoring, increase publicity efforts, and enhance the self-protection and control awareness of key populations.

OBJECTIVE To identify and evaluate the risk factors in the operation process of the vaccine supply chain ，clarify the importance of each process risk in the overall risk of the vaccine supply chain ，and provide reference for stakeholders in the vaccine supply chain to formulate risk management and control strategies. METHODS In the supply chain operation reference model，the risk factors existing in the operation of vaccine supply chain were identified ，and the vaccine supply chain risk evaluation index system was constructed. The best-worst method and entropy weight method were used to determine the subjective and objective weight of the index ，and the Lagrange multiplier method was used to solve the optimal combination weight value of the index. RESULTS & CONCLUSIONS A vaccine supply chain risk evaluation index system with 18 indexes was established. Only 67％ of the indexes reflected 85％ of the vaccine supply chain risk information. The construction of the system was reasonable. The results showed that the risk weight of production process was 0.607，which accounts for the highest weight in the overall risk of vaccine supply chain ，followed by procurement （0.234），distribution（0.102），planning（0.053）and return （0.004） process risk . When managing and controlling risks ，enterprises should attach great importance to the risk factors in vaccine production；at the same time ，enterprises should also focus on other risks such as unqualified materials for products ，mixed use of materials and so on.

Objective:To analyze the changes of spatial, seasonal, and age distribution of brucellosis among humans and animals in Gansu Province and to provide a reference for the next step in formulating prevention and control measures.Methods:Reported data of brucellosis of humans and animals in Gansu Province from 2018 to 2020 were collected. The human epidemic data were obtained from "China Disease Control and Prevention Information System", and the positive data of animals were obtained from the monthly report provided by Gansu Animal Disease Control Center. Human brucellosis was classified and analyzed according to year, month, age and region, and livestock brucellosis was classified according to year, month, population and region. ArcGIS 10.2 software was used to analyze the spatial epidemiological characteristics of the data. Measuring Geographic tool was used to calculate the shifting distance of the center of the disease incidence in humans and animals from 2018 to 2020.Results:From 2018 to 2020, a total of 6 375 cases of human brucellosis were reported in Gansu Province. The 40 - 59 age group accounted for 54.96% (3 504/6 375), 1 584 cases were reported in 2018, 1 787 cases were reported in 2019, and 3 004 cases were reported in 2020. The high incidence time of human brucellosis was July and November. A total of 48 180 brucellosis-positive animals (heads) were detected, of which 47 342 were positive sheep, accounting for 98.26% (47 342/48 180). The high incidence time of brucellosis among animals was October. Among the 14 cities (prefectures), the top cities of livestock brucellosis reported were Qingyang City, Zhangye City and Jiuquan City. The center of disease incidence among humans was located in Gulang County, Wuwei City. The center of disease incidence among animals was located in Wuwei City in 2018 and Qingyang City in 2020.Conclusions:The cases of brucellosis in humans and animals in Gansu Province are on the increase. In some areas, there are problems of separation of human and animal epidemics. It is necessary to actively strengthen monitoring and implement measures to prevent and control brucellosis in humans and animals in high-risk areas to curb the spread of the epidemic.

Objective:To analyze the situation of free cervical cancer screening from 2018 to 2020 in Lucheng District of Changzhi City, Shanxi Province.Methods:The cervical liquid-based thin-layer cytology (TCT) results of 13 043 women who underwent free cervical cancer screening at the Lucheng District Maternal and Child Health Family Planning Service Center of Changzhi City in Shanxi Province from 2018 to 2020 were retrospectively analyzed. The women with positive TCT results underwent colposcopy and biopsy.Results:Among 13 043 women, 800 women were positive for TCT, with a positive rate of 61.3/100 000. The positive rates of cervical cancer screening TCT in 2018, 2019 and 2020 were 4.82% (145/3 006), 5.63% (170/3 017) and 6.91% (485/7 020), which showed an upward trend year by year (contingency coefficient = 0.037). In 2018, 2019 and 2020, the positive rates of TCT among women aged 35-44 years old were 2.95% (31/1 052), 3.78% (42/1 112) and 4.22% (82/1 969), among women aged 45-54 years old were 5.48% (68/1 241), 6.50% (90/1 385) and 7.72% (2 258/3 341), and among women aged 55-64 years old were 6.45% (46/713), 7.31% (38/520) and 8.42% (144/1 710); the positive rates of cervical cancer screening TCT among different age groups in the same year, same age group in different years and overall different age groups in 3 years were statistically significant (all P < 0.05), and the positive rates of cervical cancer screening TCT in women aged 45-54 and 55-64 years old were higher than those in women aged 35-44 years old (all P < 0.05). Among 800 cases of positive cervical cancer screening TCT, 615 cases (76.9%) were diagnosed with cervical intraepithelial neoplasia (CIN), and the incidence rate of CIN was 4.72% (615/13 043); there was statistical differences in the incidence of CIN among different years ( P < 0.05). Conclusions:The positive rates of cervical cancer screening increase year by year from 2018 to 2020 in Lucheng District of Changzhi City, Shanxi Province. Early cervical cancer screening can detect cervical lesions in time.

Objective To evaluate the impact of concurrent nursing intervention on the quality of life of gastric cancer patients undergoing radical gastrectomy and their family caregivers. Methods A total of 200 participants undergoing radical gastrectomy in Pancreatic Stomach Surgery Department of one hospital were divided observation group (n=100) and control group (n=100) by random number table method from October 2015 to April 2016. Patients in control group were treated with traditional overall nursing, whereas patients and their family caregivers of observation group received concurrent nursing intervention. Quality of life of patients and their family caregivers was investigated with QLQ-STO22 and QOL Scale-FAMILY respectively when the patients were admitted to hospital and one year after discharged. Results The total score and the score of each dimension of quality of life of patients and their caregivers of two groups had no difference when admitted (P> 0.05). The total score of QLQ-STO22 of observation group was higher than that of the control group [(48.72±13.92) vs. (25.37±5.96)] when one year after discharged with each dimension lower (P<0.05). The total score of QOL Scale-FAMILY of the caregivers of observation group was (255.93±27.79) and (229.17±30.14) for the control group. Scores of dimensions of physical health, mental health, social adaptation of the observation group were higher than those of the control group (P<0.05), but psychological health had no significant difference (P> 0.05). Conclusions Concurrent nursing intervention could improve the quality of life of patients undergoing radical gastrectomy and their family caregivers and should be applied in clinic.
