ObjectiveTo investigate the therapeutic efficacy， influencing factors， and safety of a treatment regimen based on coblopasvir hydrochloride capsules/sofosbuvir tablets in patients with chronic hepatitis C virus （HCV） infection in a real-world setting. MethodsA total of 253 patients who attended The Third People’s Hospital of Kunming from September 1， 2021 to May 31， 2024 were enrolled， among whom there were 86 patients with compensated liver cirrhosis （CLC group） and 167 patients with chronic hepatitis C （CHC group）. The patients were treated with coblopasvir hydrochloride capsules （60 mg）/sofosbuvir tablets （400 mg） with or without ribavirin tablets for 12 weeks， and they were followed up for 12 weeks after drug withdrawal. The primary outcome measures were the rate of sustained virologic response at week 12 after treatment （SVR12） and safety， and the secondary outcome measures were the changes in liver function， renal function， blood routine， and liver stiffness measurements （LSM） after 4 weeks of treatment， after 12 weeks of treatment， and at 12 weeks after drug withdrawal. The independent-samples t test and the Mann-Whitney U test were used for comparison of continuous data between two groups， and the Friedman test was used for comparison between multiple groups， while the Bonferroni method was used for paired comparison within each group； the chi-square test was used for comparison of categorical data between two groups. The Logistic analysis was used to investigate related influencing factors. ResultsThe 253 patients with chronic HCV infection had a mean age of 49.38±8.65 years， and there were 151 male patients （59.7%）. Of all patients， 33.99% （86/253） had liver cirrhosis， 25.69% （65/253） had hypertension， 10.67% （27/253） had HIV infection， 8.70% （22/253） had diabetes， 3.95% （10/253） had liver cancer， 1.98% （5/253） had chronic hepatitis B， and 7.91% （20/253） were treatment-experienced patients. As for genotype distribution， 2.77% （7/253） had genotype 1， 12.65% （32/253） had genotype 2， 66.01% （167/253） had genotype 3， 16.60% （42/253） had genotype 6， and 1.98% （5/253） had unknown genotype. The patients had an overall SVR12 rate of 92.09%， with an SVR12 rate of 93.02% in the CLC group and 91.02% in the CHC group. The multivariate logistic regression analysis showed that age （odds ratio ［OR］=1.086， 95% confidence interval ［CI］： 1.007 — 1.170， P=0.032） and HCC （OR=9.178， 95%CI： 1.722 — 48.912， P=0.009） were independent influencing factors for sustained virologic response. Compared with baseline data， the CLC group had significant reductions in alanine aminotransferase （ALT） （χ²=107.103， P0.05）， aspartate aminotransferase （AST） （χ²=90.602， P0.05）， and LSM （χ²=42.235， P0.05） after 12 weeks of treatment， while the CHC group had significant reductions in total bilirubin （χ²=15.113， P0.05）， ALT （χ²=202.237， P0.05）， AST （χ²=161.193， P0.05）， and LSM （χ²=37.606， P0.05）. The incidence rate of serious adverse events was 1.58%， and none of the patients withdrew from drug therapy； the patients with such events were relieved after active symptomatic treatment. The incidence rate of all adverse events was 23.72%， among which fatigue （17.39%） and nausea （2.37%） were the most common adverse events， and these events often disappeared within 2 weeks or were gradually relieved after symptomatic treatment. ConclusionCoblopasvir hydrochloride capsules/sofosbuvir tablets with or without ribavirin tablets has good efficacy and safety in the treatment of chronic HCV infection.

Objective To investigate the differences of cerebral vascular morphology and serum indexes between patients with vascular cognitive impairment no dementia(VCIND)and cognitively normal cerebral vascular disease.Methods A total of 100 VCIND patients hospitalized in Quzhou Hospital of Zhejiang Medical and Health Group from June 2023 to September 2024 were included in experimental group,and 100 cognitively normal patients with cerebral vascular disease hospitalized during the same period were included in control group.Cerebral artery extension and dilation,cerebrovascular stenosis,collateral circulation establishment,inflammatory factors and lipid metabolism indexes were compared between two groups by means of cerebrovascular angiography and serum examination.The relationship between the severity of cognitive impairment and the vascular lesion of different responsibility was also explored.Results The rate of cerebral artery extension and dilation,rate of vascular stenosis in experimental group were higher than those in control group,and the rate of collateral circulation establishment was lower than that in control group(P＜0.05).The levels of interleukin-6,interleukin-1 β,tumor necrosis factor-α,total cholesterol,low density lipoprotein,apolipoprotein B and lipoprotein(a)in experimental group were significantly higher than those in control group,level of high density lipoprotein was lower than that in control group(P＜0.05).In experimental group,there were 20 cases of anterior cerebral artery vascular disease,22 cases of middle cerebral artery vascular disease,26 cases of posterior cerebral artery vascular disease,32 cases of vertebrobasilar artery vascular disease.There were no significant differences in the scores of mini-mental state examination,Montreal cognitive assessment and Hachinski ischemic scale among patients with different responsible vascular diseases(P＞0.05).Conclusion Patients with cerebral artery extension and dilation,cerebral artery stenosis,no establishment of collateral circulation,inflammatory response and abnormal lipid metabolism were high-risk groups for VCIND.Such patients need early cognitive intervention to prevent VCIND occurrence.

Within the prefrontal-cingulate cortex, abnormalities in coupling between neuronal networks can disturb the emotion-cognition interactions, contributing to the development of mental disorders such as depression. Despite this understanding, the neural circuit mechanisms underlying this phenomenon remain elusive. In this study, we present a biophysical computational model encompassing three crucial regions, including the dorsolateral prefrontal cortex, subgenual anterior cingulate cortex, and ventromedial prefrontal cortex. The objective is to investigate the role of coupling relationships within the prefrontal-cingulate cortex networks in balancing emotions and cognitive processes. The numerical results confirm that coupled weights play a crucial role in the balance of emotional cognitive networks. Furthermore, our model predicts the pathogenic mechanism of depression resulting from abnormalities in the subgenual cortex, and network functionality was restored through intervention in the dorsolateral prefrontal cortex. This study utilizes computational modeling techniques to provide an insight explanation for the diagnosis and treatment of depression.

Objective:To evaluate the clinical efficacy of endoclip papillaplasty (ECPP) for preventing recurrent choledocholithiasis after endoscopic retrograde cholangiopancreatography (ERCP).Methods:A retrospective analysis was conducted on 1 941 patients who underwent ERCP for choledocholithiasis in Henan Provincial People's Hospital from January 2019 to December 2023. A total of 250 patients who received ECPP were assigned to the ECPP group, while 251 matched controls were selected via 1∶1 year-stratified sampling into the control group. After follow-up, 209 ECPP cases and 190 controls were ultimately included in the analysis. Stone removal success rate, incidence of perioperative complications, and postoperative choledocholithiasis recurrence were compared between the two groups. Univariate and multivariate logistic regression were used to determine the risk factors for choledocholithiasis recurrence after ERCP.Results:Both groups achieved 100.0% stone removal success rate. There was no significant difference in the incidence of intraoperative perforation [0.5% (1/209) VS 1.1% (2/190), χ2=0.01, P=0.934], postoperative hyperamylasemia [21.5% (45/209) VS 17.4% (33/190), χ2=1.10, P=0.295] or post-ERCP pancreatitis [3.8% (8/209) VS 8.1% (9/190), χ2=0.20, P=0.653] between the ECPP group and the control group. The ECPP group showed significantly lower bleeding rate [5.1% (11/209) VS 12.3% (23/190), χ2=5.98, P=0.014] and choledocholithiasis recurrence rate [10.5% (22/209) VS 18.9% (36/190), χ2=5.68, P=0.017] compared with the control group. The multivariate logistic regression identified dilated common bile duct diameter ( OR=1.881, 95% CI: 1.101-3.213, P=0.021) as an independent risk factor for choledocholithiasis recurrence, while being female ( OR=0.482, 95% CI: 0.266-0.875, P=0.016) and ECPP ( OR=0.497, 95% CI:0.278-0.887, P=0.018) were protective factors. Conclusion:ECPP effectively reduces choledocholithiasis recurrence rate and bleeding risk after ERCP. ECPP and being female serve as protective factors for choledocholithiasis recurrence, while dilated bile duct diameter is an independent risk factor.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

OBJECTIVE: To explore the clinical features and genetic etiology of two Chinese patients with Cowden syndrome (CS). METHODS: Two patients diagnosed with multiple gastrointestinal polyps by gastroenteroscopy at Henan Provincial People's Hospital in September and November 2023 were selected as the study subjects. Clinical data of the patients were collected. Whole exome sequence (WES) was carried out. Candidate variants were verified by Sanger sequencing. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: 2018-03-01). RESULTS: The patients were diagnosed with multiple gastrointestinal polyps in addition with polypoid changes of the gallbladder. Genetic testing revealed that patient 1 has harbored a heterozygous c.738dupG (p.Leu247Valfs*6) variant of the PTEN gene, which was unreported previously. Patient 2 has harbored a heterozygous c.469G>T (p.Glu157Ter) variant of the PTEN gene, which was known to be pathogenic. None of their family members was found to harbor the above variants. Based on the guidelines from the American College of Medical Genetics and Genomics, both variants were rated as pathogenic (PVS1+PM2_Supporting+PP3+PP4). Bioinformatic analysis suggested that both variants can significantly affect the tertiary structure of the PTEN protein. CONCLUSION The heterozygous variants of the PTEN gene probably underlay the CS in both patients. Discovery of the novel variant has enriched the mutational spectrum of the PTEN gene.
