Objective:To understand the potential characteristics of decision-making preparation in outpatient hypertensive patients based on latent profile analysis, to identify the influencing factors of different categories of decision-making preparation levels, and to explore the performance of different decision-making preparation types in facilitation of patients involvement in treatment decision-making.Methods:Through a cross-sectional study, 350 hypertensive patients attending outpatient clinics in five different types of healthcare institutions (general hospitals, specialised hospitals and community hospitals) in Tianjin during January to May 2024 who met the inclusion and exclusion criteria were selected by the convenience sampling method as study subjects. General Information Questionnaires, Preparation for Decision Making Scale, and Facilitation of Patient Involvement Scale were used for investigation.Results:Totally 350 valid questionnaires [178 males and 172 females aged 25-89(57.24 ± 13.39)years old] were collected. The decision-making preparation score of outpatient hypertensive patients was (64.19 ± 18.69). The latent profile analysis results showed that the decision-making preparation of outpatient hypertensive patients could be divided into three potential categories: decision-making information scarcity type accounted for 20.0%(70/350), decision-making balance negotiation type accounted for 39.7%(139/350), and decision-making preparation adequacy type accounted for 40.3%(141/350). The results of multiple Logistic regression analysis showed that age, medical insurance type, occupation, and children′s condition were the influencing factors for the potential categories of decision-making preparation in outpatient hypertensive patients (all P<0.05). Age [less than 35 years old: OR(95% CI)=0.127(0.020-0.796)], occupation [on the job: OR(95% CI)=2.010 (1.034-3.906)], were the influencing factors of decision-making balance negotiation group (all P<0.05). Medical insurance type [basic medical insurance for urban employees: OR(95% CI)=0.372(0.193-0.720)], occupation [on the job: OR(95% CI)=2.500(1.270-4.920)], children′s condition[junior and senior high school: OR(95% CI)=0.391(0.190-0.802)] were the influencing factors of decision-making preparation adequacy group (all P<0.05). Conclusions:The level of promoting patient participation among outpatients with hypertension is relatively high, and there are differences in the perceived degree of promoting patient participation among patients with different types of decision preparation.It is recommended that medical staff provide decision-making related information based on the characteristics of different decision-making preparation categories of patients, encourage patients to actively participate in decision-making, and construct targeted decision support plans.

Objective To evaluate the surgical treatments of refractory sclerosing peritonitis related peritoneal dialysis.Methods Clinical data of 15 patients with refractory sclerosing peritonitis related to peritoneal dialysis treated in the General Surgery Department of the 900th Hospital of the Joint Logistics Support Force of the People's Liberation Army from June 30,2014 to May 30,2018.Among them,5 cases underwent"open abdomen peritoneal catheter removal+intestinal adhesiolysis+abdominal infection flushing and drainage with catheter",4 cases underwent"laparoscopic peritoneal catheter removal+intestinal adhesiolysis+abdominal infection flushing and drainage with catheter",3 cases underwent"laparoscopic peritoneal dialysis catheter removal+abdominal infection flushing and drainage with catheter",2 cases underwent"open abdomen peritoneal dialysis catheter removal+abdominal infection flushing and drainage with catheter",and 1 case underwent"laparoscopic examination combined with laparotomy exploration and removal of lower abdominal catheter+intestinal adhesiolysis+abdominal infection flushing and drainage with catheter".Age,gender,clinical symptoms,abdominal CT examination,peripheral blood routine,blood biochemistry,blood C-reactive protein(CRP),white blood cells,biochemistry,and aetiology of peritoneal dialysis fluid were collected and followed up,and the therapeutic effect was evaluated.Results 15 patients were transferred to the Department of Surgery after ineffective treatment in the Department of Internal Medicine.Preoperatively(after 5 days of antibiotic treatment)compared to before antibiotic treatment,there were no significant changes in blood WBC,blood NEUT％,CRP,and peritoneal fluid WBC(P＞0.05).Laparoscopic exploration or laparotomy exploration was performed,during which the peritoneal dialysis catheter was removed and the abdominal infection focus was cleared.A pelvic cavity washout drainage tube was left in place postoperatively.Fourteen patients had a good recovery after surgery,with effective control of peritonitis symptoms and no complications such as intestinal obstruction or enterocutaneous fistula.After the removal of the peritoneal dialysis catheter,all patients switched to hemodialysis.A comparison of inflammatory markers before and after surgery showed a significant decrease after surgery.Three days postoperatively compared to before surgery(after 5 days of antibiotic treatment),there were no significant changes in blood WBC,blood NEUT％,CRP,and peritoneal fluid WBC(P＞0.05).Seven days postoperatively compared to before surgery(after 5 days of antibiotic treatment),there was a significant decrease in blood WBC[(7.43±2.65)× 109/L VS(10.17±5.24)× 109/L],blood NEUT％[(88.23±9.02)％VS(85.07±11.57)％],and CRP[(152.88±113.01)mg/L VS(114.49±92.97)mg/L](P＜0.05);the peritoneal fluid WBC at 7 days postoperatively showed no significant change compared to before surgery(after 5 days of antibiotic treatment)(P＞0.05).The cases were followed up for at least 22 months,and 13 patients did not experience peritonitis or intestinal obstruction again.One patient died 39 days after surgery due to multiple organ failure,and one patient died from other causes after a 2-year follow-up.Conclusion For refractory sclerosing peritonitis related peritoneal dialysis that is ineffective in medical conservative treatment,On the basis of reasonable and effective antibiotics to control infection,surgical intervention should be actively carried out and surgical methods such as surgery should be used to control the progress of peritonitis,reduce mortality and improve the cure rate.

Objective:To explore the epileptic phenotype spectrum of SLC6A1 gene mutations and their genotype-phenotype correlation. Methods:Four hundred patients with epilepsy of unknown etiology admitted to Epilepsy Center, Department of Neurology, Second Affiliated Hospital of Guangzhou Medical University from July 2019 to July 2024 were enrolled to screen the SLC6A1 gene mutations; the clinical characteristics, mutation pathogenicity, and changes of hydrogen bond between amino acids, stability and amino acid hydrophobicity of SLC6A1 gene encoded proteins caused by missense mutations in patients with SLC6A1 gene mutations were analyzed. At the same time, a comprehensive search was conducted in PubMed, HGMD and CNKI databases to collect the publicly reported SLC6A1 gene mutations related to epilepsy up to September 8, 2024; differences in proportion of missense mutations between the two most common and featured epileptic phenotypes and proportion of missense mutations in loops of SLC6A1 gene coding proteins were analyzed. Results:Five patients carried SLC6A1 gene mutations in 400 patients with epilepsy of unknown etiology: 2 had de novo heterozygous canonical splice site mutations (c.850-1G>A and c.1324-1G>A), with phenotypes as partial epilepsy combined with severe development delay and childhood absence epilepsy combined with mild developmental delay; 2 had de novo heterozygous missense mutations (c.187G>A/p.Gly63Ser and c.1081C>A/p.Pro361Thr), with phenotypes as partial epilepsy combined with mild development delay and generalized epilepsy combined with severe development delay; and one had heterozygous missense mutation of unknown origin (c.700G>A/p.Gly234Ser), with phenotype as Lennox-Gastaut syndrome. Four de novo mutations were evaluated as having pathogenic or likely pathogenic features, and one mutation of unknown origin was evaluated as of uncertain significance. In addition, 3 missense mutations caused significant changes in number or bonding form of hydrogen bonds between amino acids of the encoded proteins, with obviously decreased stability and hydrophobicity of the encoded proteins. (2) Results of literature analysis showed that 84 SLC6A1 mutations have been reported to be associated with epilepsy; combined with the genetic results in this study, a total of 89 SLC6A1 mutations were identified, including 53 missense mutations, 33 nonsense mutations, and 3 in-frame/in-del mutations; 7 epilepsy phenotypes were involved, including 38 patients with myoclonic atonic epilepsy (MAE), 16 with epilepsy, 12 with epileptic encephalopathy, 8 with childhood absence epilepsy, 6 with childhood-onset epilepsy, 6 with generalized epilepsy, and 3 with focal epilepsy. No significant difference in proportion of missense mutations was noted between MAE and epileptic encephalopathy patients ( P>0.05); however, the proportion of missense mutations in loops of the epileptic encephalopathy patients was significantly higher than that of the MAE patients ( P<0.05). Conclusion:SLC6A1 gene mutations can cause complex and diverse epilepsy phenotype spectrum, and most patients are accompanied by developmental delay; subregional effect of the encoded protein molecules may be a potential mechanism for different clinical phenotypes between MAE and epileptic encephalopathy caused by SLC6A1 gene mutations.
