The high incidence of bleeding after peripherally inserted central catheter (PICC) catheterization increases the risk of puncture site infection and unplanned extubation. Hemostatic dressings should be used in the early stages of catheterization to reduce blood infiltration. However, new hemostatic dressings have various types and advantages, which makes them difficult to choose dressings for medical staff. This paper introduces the types and hemostatic characteristics of novel functional hemostatic dressings, reviews the hemostatic mechanism and hemostatic effect of chitosan, cyanoacrylate gum, alginate, gelatin sponge and oxycellulose dressings in PICC puncture respectively, and prospects the development of new functional hemostatic dressings. It is expected that future hemostatic dressings will move towards multifunctionality and compositeness.

Objective: To explore the expression level of PPFIA4 in hepatocellular carcinoma tissues and HCCLM3 cells and its regulation of the biological behavior of hepatocellular carcinoma. Methods : Bioinformatics analysis, Western blot, and immunohistochemistry were employed to detect the expression of PPFIA4 in tumor tissues of patients with hepatocellular carcinoma and analyze the prognosis of these patients. An siRNA plasmid was designed to knock down the expression of PPFIA4 in HCCLM3 cells. The effects of PPFIA4 knockdown on the migration and invasion abilities of HCCLM3 cells were then evaluated using scratch healing and Transwell assays. Furthermore, Western blot was utilized to detect the expression levels of epithelial-mesenchymal transition(EMT)-related protein markers in the HCCLM3 cell line after transfection with the siRNA plasmid. Results: PPFIA4 was highly expressed in hepatocellular carcinoma tissues and hepatocellular carcinoma cells( HCCLM3, Li-7, MHCC97H); the high expression of PPFIA4 indicated that the clinical stage of patients was late and the overall survival(OS) was short. After knocking down the expression of PPFIA4 in HCCLM3 cell line, the migration and invasion ability of HCCLM3 cells decreased(P<0.001) and the expression of EMT markers changed. The expression of epithelial cell marker E-cadherin increased(P<0.01), while the expression of mesenchymal markers Vimentin and N-cadherin decreased(P<0.05,P<0.01). Conclusion PPFIA4 is highly expressed in hepatocellular carcinoma tissues and hepatocellular carcinoma cell lines and is associated with poor prognosis of patients. Silencing PPFIA4 can regulate the biological behavior of hepatocellular carcinoma cells and inhibit the migration and invasion of HCCLM3 cells. The specific mechanism may be related to EMT.

Objective: To evaluate the effectiveness for the construction of "mosquito-free village" in Xuejia Village, Pujiang County, Zhejiang Province, so as to provide the guidance for the construction of "mosquito-free village" in other rural areas. Methods: Density of adult mosquitoes in Xuejia Village was investigated using light trap method and density of larval mosquitoes was investigated using larval straw method from April to November each year. Totally 30 households of villagers were randomly selected, and their awareness rates of mosquito control knowledge, mosquito control behavior forming rates and satisfaction rates were surveyed through questionnaires. Investment during construction (from August 2016 to December 2018) and maintenance period (from 2019 to 2023) of "mosquito-free village" were investigated through data review and interviews. Long-term effects of "mosquito-free village" construction in Xuejia Village were evaluated in terms of mosquito density from 2016 to 2023, effectiveness of health education for villagers, satisfaction and investment. Results: Compared with the year 2016, the densities of adult and larval mosquitoes in Xuejia Village were significantly decreased from 2017 to 2023. The average monthly density of adult mosquitoes in 2023 decreased by 98.34%, and the average monthly 100 household index of larval mosquitoes decreased by 98.45% compared to 2016. The average monthly density of adult mosquitoes from 2019 to 2023 was less than or equal to one mosquito per light trap in a night, and the average monthly 100 household index of larval mosquitoes was less than or equal to five places per 100 households. The awareness rate of mosquito control knowledge was 93.33%, the behavior forming rate was 86.67%, and the satisfaction rate was 90.00%. By December 2023, the total investment during construction and maintenance period was 450 thousand Yuan, with an average annual investment of 60.7 thousand Yuan and average annual investment of 206.61 Yuan per household. The average annual investment during maintenance period was 36.2 thousand Yuan, and the average annual investment per household was 109.70 Yuan. Conclusion The mosquito density, effectiveness of health education for villagers and satisfaction of "mosquito-free village" in Xuejia Village all meet the evaluation criteria of "mosquito-free village", and the investment is reasonable, making it suitable for promotion to other rural areas.

As an emerging field, foregut surgery has gained increasing attention internationally, focusing currently on benign foregut diseases such as gastroesophageal reflux disease (GERD), achalasia, and obesity. Ever since 2018, the establishment of independent foregut societies in the United States, Europe, and Japan has significantly propelled the advancement of foregut surgery as a distinct specialty. In China, foregut surgery has developed relatively late and the concept has not been widely promoted domestically. As the spectrum of diseases changes among the Chinese population, the number of physicians and surgeons involved in the diagnosis and treatment of foregut disease is steadily increasing. There is an urgent need to unite relevant forces to promote the development of foregut surgery as an independent discipline, so as to provide optimal care for patients with foregut diseases.

Objective:To explore the long-term efficacy of laparoscopic fundoplication for proton pump inhibitor dependent gastroesophageal reflux disease (GERD).Method:Clinical data of proton pump inhibitor dependent GERD patients who underwent fundoplication at the Rocket Force Characteristic Medical Center from Jan to Jun 2012 were analyzed, including GERD symptom score, subjective symptom relief rate, PPI discontinuation rate and surgical satisfaction, as well as recurrence and complications.Result:A total of 160 GERD patients were included in this study, with 64% of patients having respiratory symptoms. Nissen and Toupet fundoplication were performed in 43 and 117 cases, respectively, with a follow-up time of (127±3) months. The postoperative GERD symptom scores of the patients were significantly lower than before treatment (all P<0.001); The subjective relief of overall symptoms in the digestive tract and airway problem was 90% (80%, 100%) and 100%, respectively. The PPI discontinuation rate was 86%, and the overall satisfaction rate of the treatment was 92%, and the satisfaction rate of patients with respiratory symptoms was 89%. 7% of patients experienced varying degrees of symptomatic recurrence, 4% of patients re-underwent endoscopic treatment and/or laparoscopic fundoplication due to symptom recurrence. The incidence of long-term postoperative dysphagia, bloating, belching, increased exhaust, abdominal pain, diarrhea, and constipation were 11.3%, 16.9%, 0, 1.3%, 0, 2.5%, and 5.6%, respectively. Conclusions:Laparoscopic fundoplication has good long-term efficacy in the treatment of GERD. A small number of patients may experience postoperative recurrence, as well as complications such as dysphagia and gas-bloat syndrome. Most recurrent patients can achieve good therapeutic effect by redoing endoscopic treatment or redoing surgery.

Objective:To analyze the new value of gastroscopy in the diagnosis of esophageal hiatal hernia(EHH).Methods:From March 7 to September 24 in 2019, 194 patients with gastroesophageal reflux disease who received endoscopy and high resolution esophageal manometry (HREM) at the Department of Gastroesophageal Surgery, the PLA Rocket Force Medical Center were selected. The transverse diameter of esophageal hiatus and the upward length of esophagogastric junction (EGJ) were measured under endoscopy, and the relevant data of reflux esophagitis (RE) and length and pressure of lower esophageal sphincter (LES) were collected. The value of traditional method under endoscopy and esophageal hiatus transverse diameter (EHTD) method under endoscopy in the diagnosis of EHH was compared. Independent sample- t test, rank sum test and chi-square test were used for statistical analysis. Results:The detection rate of EHH by EHTD method under endescopy was higher than that by traditional method under endoscopy and HREM method (60.8%, 118/194 vs. 14.9%, 29/194 and 37.1%, 72/194), and the detection rate of EHH by HREM method was higher than that by traditional method under endoscopy, and the differences were statistically significant ( χ2=86.75, 21.82, and 24.75; all P<0.001). The proportion of RE, the upward length of EGJ and the transverse diameter of esophageal hiatus of EHH patients diagnosed by traditional method under endoscopy and EHTD method under endoscopy were all higher than those of non-EHH patients (79.3%, 23/29 vs. 28.5%, 47/165; 49.2%, 58/118 vs. 15.8%, 12/76; 2.0 (2.0, 3.0) cm vs. 0.4(0, 0.7) cm, 0.7(0, 1.6) cm vs. 0(0, 0.6) cm; (2.60±0.71) cm vs. (1.88±0.44) cm, (2.30±0.45) cm vs. (1.51±0.29) cm); the minimum resting pressure of LES and resting pressure of LES were both lower than those of non-EHH patients(3.7(0.3, 12.1) mmHg (1 mmHg=0.133 kPa) vs. 9.1(3.3, 14.2) mmHg, 6.4(2.2, 12.5) mmHg vs. 10.8 (4.7, 15.5) mmHg; (9.70±7.92) mmHg vs. (14.92±10.30) mmHg, (11.36±7.79) mmHg vs. (18.44±11.78) mmHg); the length of intraperitoneal LES were shorter than that of non-EHH patients (0(0, 1.4) cm vs. 1.1(0, 1.7) cm, 0.3(0, 1.5) cm vs. 1.3(0.4, 1.8) cm); the length of LES of EHH patients diagnosed by EHTD method under endoscopy was shorter than that of non-EHH patients ((2.83±0.63) cm vs. (3.10±0.66) cm), and the differences were statistically significant ( χ2=26.53 and 22.31, Z=-8.26 and-5.04, t=5.26 and 13.67, Z=-2.14 and-2.71, t=-2.59 and-4.63, Z=-2.58 and-3.60, t=-2.96; all P<0.05). There were no significant differences in gender, LES length, intraperitoneal LES length, minimum resting pressure of LES, resting pressure of LES and residual pressure of LES between EHH patients diagnosed by EHTD method and traditional method under endoscopy (all P>0.05). Conclusions:Endoscopy plays a significant role in the diagnosis of EHH. EHTD method under endoscopy is more accurate in the diagnosis of sliding EHH, which is worthy of clinical reference.

Objective:To evaluate the efficacy and prognostic factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with secondary acute myeloid leukemia (sAML) .Methods:In this multicenter, retrospective clinical study, adult patients aged ≥18 years who underwent allo-HSCT for sAML at four centers of the Zhejiang Hematopoietic Stem Cell Transplantation Collaborative Group from January 2014 to November 2022 were included, and the efficacy and prognostic factors of allo-HSCT were analyzed.Results:A total of 95 patients were enrolled; 66 (69.5%) had myelodysplastic syndrome-acute myeloid leukemia (MDS-AML) , 4 (4.2%) had MDS/MPN-AML, and 25 (26.3%) had therapy-related AML (tAML) . The 3-year CIR, LFS, and overall survival (OS) rates were 18.6% (95% CI 10.2%-27.0%) , 70.6% (95% CI 60.8%-80.4%) , and 73.3% (95% CI 63.9%-82.7%) , respectively. The 3-year CIRs of the M-AML group (including MDS-AML and MDS/MPN-AML) and the tAML group were 20.0% and 16.4%, respectively ( P=0.430) . The 3-year LFSs were 68.3% and 75.4%, respectively ( P=0.176) . The 3-year OS rates were 69.7% and 75.4%, respectively ( P=0.233) . The 3-year CIRs of the groups with and without TP53 mutations were 60.0% and 13.7%, respectively ( P=0.003) ; the 3-year LFSs were 20.0% and 76.5%, respectively ( P=0.002) ; and the 3-year OS rates were 40.0% and 77.6%, respectively ( P=0.002) . According to European LeukmiaNet 2022 (ELN2022) risk stratification, the 3-year CIRs of patients in the low-, intermediate-, and high-risk groups were 8.3%, 17.8%, and 22.6%, respectively ( P=0.639) . The three-year LFSs were 91.7%, 69.5%, and 65.6%, respectively ( P=0.268) . The 3-year OS rates were 91.7%, 71.4%, and 70.1%, respectively ( P=0.314) . Multivariate analysis revealed that advanced disease at allo-HSCT and TP53 mutations were independent risk factors for CIR, LFS, and OS. Conclusion:There was no significant difference in the prognosis of patients who underwent allo-HSCT among the MDS-AML, MDS/MPN-AML, and tAML groups. Advanced disease at transplantation and TP53 mutations were poor prognostic factors. ELN2022 risk stratification had limited value for predicting the prognosis of patients with sAML following allo-HSCT.
