BackgroundPrevious studies have found that patients with generalized anxiety disorder （GAD） have impaired performance in executive function， and group cognitive behavioral therapy （CBT） has been shown to be effective in alleviating negative affect in patients with GAD， while its efficacy on executive function remains unclear. ObjectiveTo explore the efficacy of group CBT on anxiety symptom and executive function in GAD patients， so as to provide references for the rehabilitation program for GAD. MethodsA total of 80 consecutive patients with GAD who were hospitalized in Sleep and Psychosomatic Medical Center of Shiyan Taihe Hospital from March 2021 to August 2022 and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria for GAD were enrolled， and they were assigned into study group （n=40） and control group （n=40） using random number table methods. All patients were subjected to routine medication treatment and regular health education， based on this， study group received group CBT once a week （6 weeks， 60 to 90 minutes per session）. At the enrollment and after 6 weeks of treatment， patients were assessed using Hamilton Anxiety Scale （HAMA） and Frontal Assessment Battery （FAB）. ResultsANOVA with repeated measures on HAMA score revealed a significant time effect （F=1 870.320， P<0.01）， no significant group effect and no significant time×group interaction effect （F=1.254， 0.293， P>0.05）. Significant time effect， group effect and time×group interaction effect were reported on FAB scores （F=311.190， 4.399， 7.021， P<0.05 or 0.01）. Further analysis indicated that FAB scores of both groups after treatment were higher than those at baseline （t=200.569， 115.401， P<0.01）.And the FAB score of study group was higher than that of control group after treatment （t=-3.211， P<0.01）. ConclusionGroup CBT combined with medication treatment for GAD may alleviate the anxiety symptoms and improve executive function in GAD patients. ［Funded by Shiyan Science and Technology Bureau Pilot Scientific Research Project （number， 21Y21）］

Combined with clinical practice,it is found that the clinical manifestations of multiple system atrophy are complex and diverse,but the pathogenesis of traditional Chinese medicine can be summarized as kidney deficiency and empty marrow as the core,and yang deficiency as an important factor.Tongyuan therapy can communicate with the brain and kidney by unblocking and regulating the governor vessel,so that the kidney essence can nourish the brain marrow,stimulate the yang qi of the whole body,nourish the original spirit and the spirit of the zang-fu organs,and nourish the muscles of the limbs.Make much of use conception vessels and abdominal front Mu point to tonify the kidney and cultivate the vital qi,strengthen the spleen and replenish qi,so that the prenatal and postnatal essence can be regulated simultaneously.Clinically,it can be based on the combination of acupuncture and Chinese medicine,which has guiding significance for the treatment of multiple system atrophy.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

【Objective】 Dyslipidemia has shown to be associated with cardiovascular, metabolic and renal diseases. This study aimed to investigate the association between residual cholesterol and the risk of subclinical renal damage (SRD). 【Methods】 A total of 2 342 participants were recruited from the previously established Hanzhong Adolescent Hypertension Study cohort. According to estimated glomerular filtration rate(eGFR) and urinary albumin-to-creatine ratio(uACR), the subjects were divided into SRD group and non-SRD group. The associations of residual cholesterol with eGFR, uACR, and the risk of SRD were analyzed by multiple linear and Logistic regression analyses. 【Results】 Residual cholesterol was positively correlated with uACR(r=0.081, P<0.001) but negatively correlated with eGFR (r=-0.091, P<0.001). Multiple linear regression analysis revealed that residual cholesterol was an influencing factor of uACR (β=0.075, P<0.001) and eGFR (β=-0.027, P<0.001) after adjustment for gender, age, smoke, alcohol, exercise, BMI, hypertension, diabetes and serum uric acid. In addition, Logistic regression analysis revealed that residual cholesterol was significantly associated with the risk of SRD independently of potential confounders [OR(95% CI)=1.387 (1.113-1.728), P<0.001]. Further subgroup analysis showed that residual cholesterol was significantly associated with the risk of SRD in women but not in men. 【Conclusion】 Residual cholesterol is a contributing factor in the risk of subclinical renal damage with gender-specific association.

【Objective】 Corin, a transmembrane serine protease that can cleave atrial natriuretic peptide precursor (pro-ANP) into atrial natriuretic peptide with smaller bioactive molecules, participates in the pathophysiological process of hypertension and cardiac hypertrophy. The purpose of this study was to explore the relationship of Corin gene variation with blood pressure responses to sodium and potassium dietary interventions. 【Methods】 In 2004, we recruited 514 participants from 124 families in 7 villages of Baoji, Shaanxi Province, China. All the subjects received a 3-day normal diet, a 7-day low-salt diet, a 7-day high-salt diet, and finally a 7-day high-salt and potassium supplementation. Fifteen single nucleotide polymorphisms (SNPs) of Corin gene were selected for final analysis. 【Results】 SNPs rs12509275 were significantly associated with diastolic blood pressure (DBP) response to low-salt diet, while rs3749584 was associated with pulse pressure (PP) response to low-salt diet.SNP rs3749584 and rs10517195 were significantly associated with PP response to high-salt diet. In addition,rs17654278 were significantly associated with systolic blood pressure (SBP) response to high-salt and potassium supplementation, rs2271037 was significantly correlated with DBP responses to high-salt and potassium supplementation, and rs4695253, rs12509275, rs2351783, rs36090894 were significantly associated with PP response to high-salt and potassium supplementation. 【Conclusion】 Corin gene polymorphisms were associated with blood pressure response to sodium and potassium, suggesting that Corin gene may be involved in pathophysiological process of salt sensitivity and potassium sensitivity.

【Objective】 4-like protein with down-regulated expression and development in neural precursor cells (NEDD4L) plays an important role in blood pressure (BP) regulation and sodium homeostasis by regulating epithelial sodium channel protein. In this study, we aimed to explore the relationship of NEDD4L gene polymorphisms with BP responses to sodium and potassium intake. 【Methods】 In 2004, 514 subjects from 124 families in Meixian County, Shaanxi Province, were recruited to establish a salt-sensitive hypertension study cohort. All the subjects received a 3-day baseline survey, a 7-day low-salt diet, a 7-day high-salt diet, and finally a 7-day high-salt and potassium supplementation. Their BP was measured and peripheral blood samples were collected at different intervention periods. The 14 gene polymorphisms of NEDD4L gene were genotyped and analyzed by MassARRAY platform. 【Results】 BP decreased on a low-salt diet, and significantly increased on a high-salt diet, and decreased again after potassium supplementation. NEDD4L SNPs rs74408486 were significantly associated with systolic BP, diastolic BP and mean arterial pressure responses to the low-salt diet. SNPs rs292449 and rs2288775 were significantly associated with pulse pressure response to the high-salt diet. In addition, SNPs rs563283 and rs292449 were significantly associated with diastolic BP, mean arterial pressure, and pulse pressure responses to high-salt and potassium supplementation diet. 【Conclusion】 NEDD4L gene polymorphisms were significantly associated with BP responses to sodium and potassium intake, suggesting that NEDD4L gene may be involved in the development of salt sensitivity and potassium sensitivity.

【Objective】 Based on our previously established salt-sensitive hypertension cohort, we aimed to examine the association of genetic variants in uromodulin with blood pressure(BP) responses to dietary interventions of sodium and potassium intake. 【Methods】 In 2004, 514 subjects from 124 families in Mei County, Shaanxi Province, were recruited to establish the salt-sensitive hypertension study cohort. Among them, 333 non-parent subjects were selected and sequentially maintained on a normal-diet for 3 days, low-salt diet for 7 days, then a high-salt diet for 7 days and a high-salt diet with potassium supplementation for another 7 days. Thirteen single nucleotide polymorphisms(SNPs) in the uromodulin gene were genotyped on the MassARRAY platform. 【Results】 BP levels decreased from the baseline to low-salt diet, increased from low-salt to high-salt diet, and decreased again from the high-salt diet to the high-salt plus potassium supplementation intervention. SNPs rs77875418 and rs4997081 of the uromodulin gene were significantly associated with diastolic BP(DBP) and mean arterial pressure(MAP) responses to high-salt diet. In addition, SNPs rs77875418, rs79245268, rs4293393, rs6497476, rs4997081, rs13333226, and rs12917707 were significantly associated with systolic BP(SBP), DBP, and MAP responses to high-salt diet with potassium supplementation. 【Conclusion】 Genetic variants in uromodulin gene are significantly associated with BP responses to sodium and potassium supplementation, suggesting that uromodulin may be mechanistically involved in BP sodium-sensitivity and potassium-sensitivity.

【Objective】 M3 muscarinic acetylcholine receptor(M3 receptor), encoded by CHRM3 gene, is widely distributed in the cardiovascular system and plays an important role in cardiac regulation. The aim of this study was to assess the association of genetic variants in M3 receptor with blood pressure(BP) responses to controlled dietary sodium and potassium interventions. 【Methods】 A total of 333 subjects from 124 families were recruited from the rural areas of northern China. After a three-day baseline observation, they were sequentially on a seven-day low-salt diet, a seven-day high-salt diet, and a seven-day high-salt diet plus potassium supplementation. Thirteen CHRM3 single nucleotide polymorphisms(SNPs) were selected for analysis. 【Results】 SNP rs10802811 of the CHRM3 was significantly associated with diastolic BP(DBP) and mean arterial pressure(MAP) responses to both low-salt and high-salt diets while SNPs rs6429147, rs373288072, rs114677844 and rs663148 showed significant associations with systolic BP(SBP) and MAP responses to high-salt diet. In addition, SNP rs6692904 was significantly associated with SBP, DBP and MAP responses to high-salt diet with potassium supplementation. 【Conclusion】 Genetic variants in M3 receptor are significantly associated with BP responses to sodium and potassium intervention, suggesting that M3 receptor may be mechanistically involved in BP salt and potassium sensitivity.

Objective:To investigate the association between body mass index (BMI) trajectories in children and adolescents and subclinical renal damage (SRD) in adulthood.Methods:4 623 participants aged 6-18 years old were recruited from the ongoing cohort of Hanzhong adolescent hypertension study in 1987, and the subjects were followed up in 1989, 1992, 1995, 2005, 2013 and 2017, respectively. Group-based trajectory modeling was used to identify distinct BMI trajectories in longitudinal analysis. Generalized linear model was applied to examine the association between different BMI trajectories and SRD incidence in adulthood.Results:A total of 2 678 subjects from childhood to adulthood were enrolled in this study. All subjects were divided into three groups according to three distinct BMI trajectories: low-increasing BMI group ( n=1 017), moderate-increasing BMI group ( n=1 353), and high-increasing BMI group ( n=308). Over follow up for 30 years, a total of 248 participants (9.3%) developed SRD. Urinary albumin-to-creatinine ratio (uACR) in low to high-increasing BMI group was 0.9(0.6, 1.4), 1.0(0.7, 1.7), 1.6(0.8, 3.2), respectively ( P trend<0.001), and estimated glomerular filtration rate was 98.5(87.6, 111.6) , 96.2(86.4, 109.7), 95.3 (87.5, 125.0) ml·min -1·(1.73 m 2) -1, respectively ( P trend=0.025). The generalized linear model analysis showed that uACR was increased linearly from low to high-increasing BMI group [ β=3.16(95% CI 1.02-5.31), Ptrend=0.004]. There was no correlation or linear trend between BMI trajectory and estimated glomerular filtration rate [ β=-2.30(95% CI-5.18-0.57), Ptrend=0.117]. Compared with the low-increasing BMI group, the high-increasing BMI group had greater odds of experiencing SRD in adulthood after adjusting for multiple confounders such as age, gender, medical history and lifestyle ( OR=2.83, 95% CI 1.84-4.36, Ptrend<0.001). Conclusions:Higher BMI trajectorie is correlated with higher level of uACR and risk of SRD in middle age. Identifying long-term BMI trajectorie from early age may assist in predicting individuals′ renal function in later life.

【Objective】 Based on our previously established salt-sensitive hypertension cohort, we conducted chronic salt loading and potassium supplementation interventions, aiming to examine the association between genetic variants in renalase and blood pressure (BP) responses to dietary interventions of salt and potassium intake. 【Methods】 In 2004, 514 subjects from 126 families were recruited in Shaanxi Province to establish the salt-sensitive hypertension study cohort. Among them, 334 non-parent subjects were selected and sequentially maintained on a low-salt diet for 7 days, then a high-salt diet for 7 days and a high-salt diet with potassium supplementation for another 7 days. Ten single nucleotide polymorphisms (SNPs) in the renalase gene were genotyped on the MassARRAY platform. 【Results】 SNP rs2576178 of the renalasegene was significantly associated with systolic BP (SBP) and mean arterial pressure (MAP) responses to low-salt intervention (SBP: β=-2.730, P<0.05; MAP: β=-1.718, P<0.05). In addition, SNP rs12356177 was significantly associated with diastolic BP response to low-salt diet (β=-1.608, P<0.05). However, we did not find any association for the renalase SNPs with BP response to high-salt diet with potassium supplementation reached nominal statistical significance. 【Conclusion】 Genetic variants in renalase gene are significantly associated with BP response to low-salt diet, suggesting that renalase may be mechanistically involved in BP salt-sensitivity.
