Primary hyperaldosteronism(PHA),the most common cause of secondary hypertension,can lead to cardiovascular and renal damage events.Early diagnosis and accurate typing of PHA is crucial to the choice of treatment options,and its diagnostic modalities usually include prone test screening,captopril test characterization and adrenal vein blood sampling for localization and typing diagnosis.However,with the development of imaging,molecular biology and morphology technologies,the use of nuclear medicine PET-CT,genetic testing and pathological diagnostic methods can also be used to accurately typify PHA.New technologies such as adrenal artery embolization and adrenal radiofrequency ablation are also increasingly being used in the treatment of PHA,which have the advantages of shorter and less costly surgery,fewer postoperative complications,and quicker recovery.This article provides a review of the developments in the screening,diagnosis and treatment of PHA with a view to informing clinical practice.

Objective:To explore the independent risk factors for predicting the right adrenal dominant secretory side in patients with primary hyperaldosteronism (PHA), so as to construct and verify the prediction model of the dominant secretory side, and provide evidence for the diagnosis and treatment of PHA patients.Methods:Clinical data of 82 PHA patients undergoing adrenal vein sampling (AVS) admitted to the Second Affiliated Hospital of Guangzhou Medical University from January 2015 to July 2023 were retrospectively analyzed, and divided into the training set (58 cases) and the verification set (24 cases) according to the ratio of 7∶3. Single factor and multiple factor logistic regression analysis were used to screen out the risk factors for predicting the right adrenal dominant secretory side, and then combined with the risk factors to build the prediction model of the dominant secretory side. The predictive efficiency and clinical applicability of the predominance secretory nomogram prediction model were verified by drawing receiver operating characteristic (ROC) curve, calibration curve and decision curve analysis (DCA curve).Results:(1) Univariate and multivariate logistic analysis showed that the concentration of aldosterone (ALD2) in inferior vena cava and the results of adrenal CT imaging suggested that the right adrenal unilateral nodule (RJJ) were independent risk factors for the occurrence of right adrenal dominant secretion in PHA patients undergoing AVS (all P<0.05). (2) The area under ROC curve (AUC) corresponding to ALD2 variable was 0.898(95% CI: 0.735 7-0.986 1), and the sensitivity and specificity were 95.2% and 81.1%, respectively. The corresponding AUC of RJJ variable was 0.750(95% CI: 0.683 1-0.976 3), and the sensitivity and specificity were 90.5% and 86.7%, respectively. The AUC of the two variables in the verification set were 0.926 and 0.778, respectively. (3) Calibration curve and DCA curve showed that the prediction model had good consistency and clinical applicability, and can produce good clinical benefits. Conclusions:ALD2 and adrenal CT results suggest that RJJ is an independent risk factor for the prediction of the right adrenal dominant secretory side, and the prediction model based on these risk factors has good predictive efficacy and clinical applicability.

Objective:To explore the relationship among physical exercise, self-control, and mobile phone dependence in adolescents.Methods:The entire group of random sampling method was used to extract 882 students from five junior high schools in Nanchang city from September 2020 to March 2021.A longitudinal survey was conducted using the sports activity rating scale, self control scale, and adolescent mobile phone dependence scale on all participants for 2 times with an interval for 6 months.The questionnaire results in the first stage were marked as T1.The questionnaire results in the second stage were marked as T2.SPSS 26.0 statistical software was used to conduct reliability analysis, common method bias test and Pearson correlation analysis on each variable in sequence.AMOS 23.0 was used for cross-lag analysis to explore the relationship among physical exercise, self-control and mobile phone dependence.Results:The score of physical exercise of adolescents was (17.71±5.62), the score of self-control was (51.48±9.71), and the score of mobile phone dependencies was (56.67±12.93). Adolescent physical exercise, self-control, and mobile phone dependence were all related to stability across time.There were positive correlation between T1 physical exercise and T2 physical exercise ( r=0.489), T1 self-control and T2 self-control ( r=0.482), as well as T1 mobile phone dependencies and T2 mobile phone dependencies ( r=0.498)(all P<0.01). Cross-lag analysis showed that: adolescent physical exercise behavior could unidirectionally predict self-control( β=0.197, P<0.01)and mobile phone dependence( β=-0.224, P<0.01) after 6 months, and self-control could predict the mobile phone dependence( β=-0.560, P<0.01) of junior high school students after 6 months.The mediating effect results showed that self-control had a mediating effect between physical exercise and mobile phone dependence of junior high school students, there were gender differences.The mediating effect accounted for 22.22%(-0.018/-0.081). Conclusion:Physical exercise can indirectly reduce the mobile phone dependence of junior high school students by affecting self-control.

Objective: To obtain chimeric antigen receptor macrophages ( CAR-M) targeting HER2 stably transfected． Methods : CAR lentivirus vector targeting HER2 was constructed and infected with human monocytic leukemia cell line (THP-1) ．CAR THP-1 cells with green fluorescent labeling were selected by sorting flow cytometry and continued to be cultured in vitro．The CAR THP-1 cells targeting HER2 were co-cultured with the endometrial cancer cell line Ishikawa with negative and positive HER2 expression，and their targeted phagocytosis of CAR-M to HER2 positive tumor cells was detected by imaging flow cytometry ，and the targeted phagocytosis efficiency of CAR-M to HER2 positive tumor cells was detected by flow cytometry. Results : CAR lentivirus infection with THP- 1 cells was less efficient ; After co-culture with cancer cells，flow cytometry and imaging flow cytometry showed that CAR THP-1 cells had enhanced phagocytosis of HER2 positive Ishikawa cells compared with the empty body group (P＜0. 01) ． Conclusion In this experiment，CAR THP-1 cell line targeting HER2 was established by constructing CAR lentivirus vector and transfecting THP-1 cells ，and it was proved that CAR THP-1 could phagocytize HER2 positive Ishikawa cells through specific targeting.

Objective To compare the curative effect of fixation of adolescent tibial intercondylar emi-nence fracture among suture anchor,hollow screw and wire. Methods Forty-six adolescent cases of the tibial intercondylar eminence fracture treated with surgical treatment were selected from January 2010 to June 2016 and divided into three groups refer to intra-operative fixation suture anchor group(Group A),hollow screw group (Group B)and wire group(Group C).Duration of treatment,total operation time,hospital stay and surgery times were recorded. All patient condition was assessed with the Lysholm,Tegner,IKDC and VAS score. Results All patients received an average of 13(11~14)months follow-up visit. No blood-vessel,nerve and osteoepiphysis injured,infection and fracture displacement occurred.Before receiving treatment,difference in Lysholm,Tegner, IKDC and VAS score of group A,B and C showed no statistical difference.When it comes to hospitalization condi-tion,data were as follows.Group A/B/C:operation time(80.67 ± 16.68/114.00 ± 20.28/111.88 ± 20.07)min, hospital stay(8.40 ± 1.12/ 15.47 ± 1.25/ 15.19 ± 1.17)d,surgery times(1/2/2)times. Moreover,compared with those before operation and after operation in both of groups,the Lysholm,Tegner,IKDC and VAS score were improved(P < 0.05). Besides,the Lysholm,Tegner,IKDC and VAS score of group A,B and C did not have statistically significant difference yet after post treatment(P>0.05).Conclusions The curative effect of fixation of adolescent tibial intercondylar eminence fracture among suture anchor,hollow screw and wire was similar. By contrast,the fixation of fracture by use of suture anchor can decrease operation time and hospital stay to some extent. It had advantage of need not to have a second operation to remove the internal fixation and can be used in preference.

Objective To understand the status of the HR and payroll system at county public hospitals in Guangxi,and to put forward basic path and targeted policy suggestions of the reform.Methods In June 2016,a field survey was made on the HR and payroll status of county-level public hospitals in 14 prefecture level cities in Guangxi,along with descriptive and inferential analysis.Results During 2013 to 2015 period,the total income of the sample hospitals had increased to some extent, mainly due to rise of hospitals'business revenue.The multiple of medical workers''wages, given some rise, remained stable compared to average wages of urban employees,as their monthly after-tax income ranged but 3 001-5 000 yuan in most cases.A large salary gap was found between those within the staffing plan and those beyond, and the latter has higher turnover rate.The performance appraisal system is poorly accepted by medical workers,as only 1.34%of them hold their current pay as ideal.Conclusions The reforms should prioritize the payroll system, better the performance appraisal system, upgrade the staffing plan management and innovate HR recruitment mode.These measures should constitute the reform of the HR and payroll system at county public hospitals.

OBJECTIVE:To provide unified standard for assessing the comprehensive ability of food and drug inspection and testing institutions in Guangxi Zhuang autonomous region. METHODS:The comprehensive ability evaluation index system for food and drug inspection and testing institutions in Guangxi Zhuang autonomous region was drafted by literature review. Indexes of the evaluation index system were determined by Delphi expert consultation,and the weights were calculated by analytic hierarchy pro-cess (AHP). RESULTS:Literature review and expert consultation had constructed the comprehensive ability evaluation index sys-tem for food and drug inspection and testing institutions in Guangxi Zhuang autonomous region,including 6 first-level indexes,16 second-level indexes and 35 third-level indexes. AHP had determined the weights of indexes at all levels,and the weights of the 6 first-level indexes as basic conditions,management system,testing ability,work performance,scientific research and satisfaction degree,were respectively 0.1898,0.1233,0.2280,0.1915,0.1551 and 0.1124,in which testing ability held the highest weight. CONCLUSIONS:A set of scientific and suitable evaluating index system for food and drug inspection and testing institu-tions in Guangxi Zhuang autonomous region has been constructed,and the weights of indexes at all levels have been determined, which can provide clear and unified standard for conducting comprehensive ability system evaluation in each inspection and testing institution in Guangxi Zhuang autonomous region.
