Objective:To investigate the relationship between blood pressure trajectories and blood pressure variability with the risk of target organ damage in Chinese population from childhood to middle age.Methods:This study is a population-based, long-term follow-up cohort study. Participants who had their blood pressure measured at least 5 times in the Hanzhong Adolescent hypertension cohort from 1987 to 2023 were included in this study. Group-based trajectory modeling was used to identify different systolic and diastolic blood pressure trajectories, and the subjects were divided into low-increasing group, moderate-increasing group and high-increasing group according to blood pressure trajectories. Blood pressure variability was assessed using standard deviation (SD), variability independent of the mean (VIM), and average real variability (ARV). Target organ damage was evaluated during the final follow-up in 2023 (middle age). Logistic regression models were used to analyze the relationship between blood pressure trajectories and blood pressure variability with the risk of target organ damage.Results:A total of 2 447 subjects were included, with a median age of 48 years, of whom 1 373 were male (56.1%). Based on systolic blood pressure, 868 were in the low-increasing group, 1 238 in the moderate-increasing group, and 341 in the high-increasing group. For diastolic blood pressure, the distribution was 894, 1 263 and 290, respectively. Compared with the low-increasing group of systolic blood pressure, the moderate-increasing group (arteriosclerosis: OR=4.14, 95% CI 2.96-5.79; proteinuria: OR=2.06, 95% CI 1.38-3.07; left ventricular hypertrophy: OR=1.68, 95% CI 1.00-2.82) and high-increasing group (arterial stiffness: OR=15.44, 95% CI 10.14-23.50; proteinuria: OR=5.80, 95% CI 3.63-9.29; left ventricular hypertrophy: OR=2.93, 95% CI 1.55-5.53) had a higher risk of target organ damage (all P<0.005). The moderate-increasing group of diastolic blood pressure had a higher incidence of arterial stiffness ( OR=3.72, 95% CI 2.69-5.12) and proteinuria ( OR=1.67, 95% CI 1.15-2.42) than the low-increasing group (all P<0.005), while the high-increasing group had a significantly higher risk of all type of target organ damage compared to the low-increasing group (arterial stiffness: OR=10.84, 95% CI 7.08-16.61; proteinuria: OR=3.72, 95% CI 2.31-5.99; left ventricular hypertrophy: OR=2.38, 95% CI 1.23-4.59; all P<0.005). Additionally, higher systolic blood pressure variability was associated with an increased incidence of arterial stiffness (SD: OR=2.25, 95% CI 1.96-2.57; VIM: OR=1.64, 95% CI 1.45-1.86; ARV: OR=1.70, 95% CI 1.50-1.93) and proteinuria (SD: OR=1.65, 95% CI 1.44-1.89; VIM: OR=1.41, 95% CI 1.22-1.63; ARV: OR=1.45, 95% CI 1.26-1.67; all P<0.005). The results for diastolic blood pressure variability indicators were similar to those for systolic blood pressure. Conclusion:Early-life blood pressure trajectories are predictive of target organ damage risk in middle age. Higher blood pressure variability is related to an increased risk of arterial stiffness and proteinuria, but was less associated with left ventricular hypertrophy. Focusing on the risk of high blood pressure early in life can help prevent the occurrence of target organ damage in middle age.

Isavuconazole represents a novel gen-eration of triazole antifungal agents for the treat-ment of invasive trichothecenes in adults.The phar-macokinetic profile of isavuconazole differs in spe-cial populations,including children,patients with ex-tracorporeal membrane oxygenation,those with he-patic or renal injury,patients undergoing blood puri-fication,and critically ill individuals and solid organ transplant recipients.These differences impact the safety and efficacy of patient treatment.This article presents the latest progress in the pharmacokinetic study of isavuconazole in these special populations.

Objective To investigate the clinical features of chronic hepatitis C(CHC)patients with hepatitis C virus genotype 3(HCV GT3)infection and the risk factors for disease progression.Methods A multicenter retrospective cohort study was conducted among 1 002 CHC patients from 11 clinical centers in Northwest China from December 2017 to November 2023,and according to their genotype,they were divided into GT1,GT2,GT3,and GT6 groups.Clinical features were compared between the patients with different genotypes.The one-way analysis of variance was used for comparison of normally distributed continuous data between groups,and the Scheffe test was used for further comparison between two groups.The Kruskal-Wallis H test was used for comparison of data with skewed distribution between groups;the chi-square test or Fisher test was used for comparison of categorical data between groups.The multivariate logistic regression analysis was used to explore the influencing factors for the progression of CHC to liver cirrhosis.Results In terms of the genotype,there were 427 patients with GT1 infection,242 with GT2 infection,299 with GT3 infection(210 patients with GT3a infection,87 with GT3b infection,and 2 with unclassified genotype),and 34 with GT6 infection.The patients with GT3 infection had a significantly younger age than those with GT1 infection(51.3±0.5 years vs 53.2±0.6 years,P<0.05)or GT2 infection(51.3±0.5 years vs 53.7±0.8 years,P<0.05),and for the patients with liver cirrhosis,the patients with GT3 infection had a significantly younger age than those with GT1 infection(52.1±0.5 years vs 59.4±0.9 years,P<0.001)or GT2 infection(52.1±0.5 years vs 58.1±1.1 years,P<0.001).Among the patients with GT3 infection,male patients accounted for 77.9%and the patients with liver cirrhosis accounted for 46.2%,which were significantly higher than those among the patients with GT1,GT2 or GT6 infection(all P<0.001).At baseline,the patients with GT3 infection had significantly higher levels of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)than those with GT1 or GT2 infection,significantly higher aspartate aminotransferase-to-platelet ratio index(APRI)and fibrosis-4(FIB4)than those with GT1,GT2 or GT6 infection,a significantly lower platelet count(PLT)than those with GT2 or GT6 infection,a significantly higher level of alpha-fetoprotein than those with GT2 or GT6 infection,and a significantly lower level of albumin(Alb)than those with GT6 infection(all P<0.05).There were no significant differences between the patients with GT3a infection and those with GT3b infection in age,sex,the proportion of patients with liver cirrhosis,comorbidities,HCV RNA quantification,PLT,ALT,AST,alkaline phosphatase,Alb,APRI,and FIB-4(all P>0.05).The multivariate logistic regression analysis showed that PLT≤150×109/L(odds ratio[OR]=10.72,95%confidence interval[CI]:5.76-35.86,P<0.001)and Alb≤35 g/L(OR=3.74,95%CI:1.22-11.45,P=0.021)were risk factors for liver cirrhosis.Conclusion Most CHC patients with GT3 infection are male in Northwest China,and compared with the patients with other genotypes,such patients tend to have a younger age of onset and higher degrees of liver inflammation activity and fibrosis.Low PLT and a low level of Alb are risk factors for progression to liver cirrhosis in CHC patients with GT3 infection.

Objective:To investigate the current application of blood purification in the treatment of acute poisoning within Jiangsu Province and to evaluate the impact of extracorporeal blood purification on the clinical outcomes of critically poisoned patients.Methods:This multicenter, cross-sectional real-world observational study followed patients presenting with poisoning to the emergency departments of nine hospitals in Jiangsu Province between June 2015 and May 2019. Data were collected on demographic characteristics, vital signs within the first hour of emergency presentation, treatment modalities, length of hospital stay, and survival outcomes. Clinical data from patients who underwent extracorporeal blood purification were compared with those who did not, using the Wilcoxon rank-sum test and Chi-square test.Results:A total of 4 178 poisoning cases were included between June 2015 and May 2019. Among them, 21.7% (908/4 178) received blood purification therapy, while 78.3% (3 270/4 178) did not. Hemoperfusion (90.4%) was the most frequently employed method, followed by continuous renal replacement therapy (CRRT) (4.4%). In combined blood purification modalities, 4.8% underwent hemoperfusion combined with CRRT, 0.1% received hemoperfusion with plasma exchange, and another 0.1% underwent hemoperfusion combined with both CRRT and plasma exchange. Among patients who underwent blood purification, pesticide poisoning was the most prevalent (76.3%), with the most common toxic agents being paraquat (23.7%), dichlorvos (8.7%), methamidophos (5.2%), omethoate (4.0%), and glyphosate (3.7%). Compared to the non-blood purification group, patients in the blood purification group were more likely to present within the first hour with a low Glasgow Coma Scale (GCS) score (3-8) (22.6% vs. 9.7%, P <0.05), low mean arterial pressure (8.0% vs. 3.2%, P <0.05), longer hospital stays [5(3,9) days vs. 2(1,4) days, P <0.05] and a higher in-hospital mortality rate (21.1% vs. 5.3%, P <0.05). Follow-up via telephone 28 days after discharge revealed a survival rate of 78.9%, with a mortality rate of 21.1% in the blood purification group. Conclusions:Hemoperfusion is the most commonly utilized blood purification technique for treating poisoning in Jiangsu Province, with pesticides being the primary toxic agents treated. Although the mortality rate is higher in the blood purification group, the intervention may still contribute to improved patient outcomes.

Objective:To explore the safety and feasibility of circular-stapled anastomosis using purse-string suture device with multi-functional seal cap in totally laparoscopic total gastrectomy esophagojejunostomy.Methods:This technique is based on a new purse-string suture device and multi-functional seal cap. After laparoscopic total gastrectomy and D2 dissection, the purse-string suture device was inserted into the abdominal cavity through the multi-functional sealing cover and placed in a proper position along the distal esophagus for formation of purse-string suture. Anvils were introduced inside the purse-string after its fire, and a 25-mm cicular stapler was inserted to the abdominal cavity through the multi-functional seal cap, following laparoscopic end-to-side circular-stapled esophagojejunostomy.Results:From November 2024 to December 2024, three patients with gastric cancer underwent laparoscopic total gastrectomy with D2 lymphadenectomy and successfully accepted laparoscopic esophagojejunostomy based on the purse-string suture device with multi-functional seal cap. The operation time was 180 minutes, 260 minutes and 240 minutes, respectively with the time of anvil pacement of 4 minutes,4 minutes, 4.5 minutes for the three cases. The bleeding volume of each was 100 ml respectively. The proximal esophageal margins were 2 cm from the tumor, and the margins were negative for tumor. No extravasation of contrast agent was seen in the postoperative oral contrast anastomosis. All three patients were followed up for 33, 30, and 25 days after the operation, and no anastomotic bleeding, leakage, or other related complications were found.Conclusion:The circular anastomosis using purse-string suture device with multi-functional seal cap in totally laparoscopic total gastrectomy esophagojejunostomy is safe and feasible, which is a promising novel choice for laparoscopic radical treatment of gastric cancer with total gastrectomy oesophagojejunostomy.

Conclusion:Early-life blood pressure trajectories are predictive of target organ damage risk in middle age. Higher blood pressure variability is related to an increased risk of arterial stiffness and proteinuria, but was less associated with left ventricular hypertrophy. Focusing on the risk of high blood pressure early in life can help prevent the occurrence of target organ damage in middle age.

【Objective】 To investigate the association between genetic variations in the glucagon-like peptide-1 receptor (GLP-1R) gene and BP responses to sodium and potassium intake. 【Methods】 A total of 514 subjects from 124 families were recruited in Meixian County, Shaanxi Province, in 2004, resulting in the establishment of a "salt-sensitive hypertension study cohort" . The subjects followed a dietary regimen which involved a normal diet for 3 days, a low-salt diet for 7 days, a high-salt diet for 7 days, and a high-salt potassium-supplemented diet for 7 days. BP measurement was conducted at different intervention periods, and peripheral blood samples were collected. Additionally, eight single nucleotide polymorphisms (SNPs) of the GLP-1R gene were genotyped using the MassARRAY detection platform. 【Results】 The GLP-1R gene SNP rs9462472 exhibited a significant association with systolic BP, diastolic BP, and mean arterial pressure response to high-salt intervention. Similarly, SNP rs2268637 showed a significant association with systolic BP response to high-salt intervention. Furthermore, SNP rs2268637 was significantly associated with systolic BP and mean arterial pressure responses to high-salt plus potassium supplementation intervention. 【Conclusion】 Our findings indicate a significant association of genetic variations in the GLP-1R gene with BP responses to sodium and potassium intake. This suggests that the GLP-1R gene plays a role in the regulation of BP salt sensitivity and potassium sensitivity.
