Objective To evaluate the therapeutic efficacy for surgical treatments among patients with hepatic cystic echinococcosis in Gansu Province from 2006 to 2023, so as to provide insights into optimization of the diagnosis and treatment strategies against hepatic cystic echinococcosis. Methods The demographic and clinical data of all echinococcosis cases included in central government fiscal transfer payment program for echinococcosis control and undergoing surgical treatments in Gansu Province from 2006 to 2023 were captured. Hepatic cystic echinococcosis patients with complete medical records and follow-up data were included in the study, and patients’ characteristics, including hospital where patients received diagnosis and treatment, methods of case identification, year of surgery, classification of lesions, number of lesions, size of lesions, course of disease, surgical methods, and post-surgical follow-up data. The cure and recurrence of hepatic cystic echinococcosis were evaluated according to the Guidelines for Management of Echinococcosis Patients in the Central Government Fiscal Transfer Payment Program, and the cure and recurrent rates were calculated. Results Data were collected from 1 686 surgical patients with hepatic cystic echinococcosis. According to the inclusion and exclusion criteria, 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments were included during the period from 2006 to 2022, including 1 166 cured patients (95.42%) and 88 patients with postsurgical recurrence (7.20%), and the cure rate of surgical treatments appeared a tendency towards a rise among patients with hepatic cystic echinococcosis from 2008 to 2022 (χ²_trend = 19.39, P < 0.05). The cure rates of hepatic cystic echinococcosis were 100% (177/177), 94.81% (128/135) and 94.62% (861/910) among patients detected through regular physical examinations, screened by the central government fiscal transfer payment program for echinococcosis control, and those who passively sought healthcare services, respectively (χ² = 9.95, P < 0.05). The cure rates of hepatic cystic echinococcosis were 95.96% (1 046/1 090) among patients with a disease course of 2 years and less and 90.90% (120/132) among patients with a disease course of over 2 years (χ² = 6.87, P < 0.05), and there were significant differences in the cure rates among patients with hepatic cystic echinococcosis in terms of number of lesions (χ² = 24.44, P < 0.05) and surgical methods (P < 0.05). The cure rate of hepatic cystic echinococcosis patients was significantly higher following initiation of the central government fiscal transfer payment program for echinococcosis control (96.06%, 1 096/1 141) than before the program (86.42%, 70/81) (χ² = 16.06, P < 0.05), and the cure rate of hepatic cystic echinococcosis patients was significantly higher in designated hospitals (96.48%, 741/768) than in non-designated hospitals (93.37%, 366/392) (χ² = 5.78, P < 0.05). The median follow-up period was 4 (interquartile range, 7) years among 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments. The recurrent rate of hepatic cystic echinococcosis appeared a tendency towards a decline from 2008 to 2022 (χ²_trend = 36.86, P < 0.05), with a reduction from 23.08% (9/39) in 2008 to 1.85% (1/54) in 2021, and the post-surgical recurrence rate of hepatic cystic echinococcosis was lower following initiation of the central government fiscal transfer payment program for echinococcosis control (5.87%, 67 / 1 141) than before the program (25.93%, 21/81) (χ² = 45.51, P < 0.05). In addition, the post-surgical recurrence rate of hepatic cystic echinococcosis was higher in non-designated hospitals (10.46%, 41/392) than in designated hospitals (5.60%, 43/768) (χ² = 9.12, P < 0.05), and there was a significant difference in the post-surgical recurrence rate among patients with hepatic cystic echinococcosis in terms of surgical methods (P < 0.05), with the highest recurrence rate (11.54%) seen among patients undergoing percutaneous fine-needle aspiration of cyst fluids-based surgical procedures (P < 0.05). Conclusion Since the initiation of the central government fiscal transfer payment program for echinococcosis control in Gansu Province in 2006, an increase in the surgical cure rate and a reduction in the recurrence of hepatic cystic echinococcosis had been found among patients with hepatic cystic echinococcosis, indicating a high overall therapeutic efficacy.

ObjectiveTo investigate the value of Fried Frailty Phenotype （FFP）， liver frailty index （LFI）， and Short Physical Performance Battery （SPPB） in predicting 2-year all-cause mortality and decompensation events in patients with liver cirrhosis. MethodsA total of 277 patients with liver cirrhosis who were hospitalized in Beijing Friendship Hospital， Capital Medical University， from December 2020 to December 2021 were enrolled， and FFP， LFI， and SPPB were used to assess the state of frailty. Based on the scores of each tool， these patients were divided into frail and non-frail groups. These three tools were compared in terms of consistency and independent predictive performance. The primary endpoints were 2-year all-cause mortality rate and composite endpoints （death+decompensation events）， and the Cox regression analysis， the receiver operating characteristic （ROC） curve， net reclassification index （NRI）， and integrated discrimination improvement （IDI） index were used to analyze the predictive value of the three tools. Normally distributed continuous data were compared between two groups using the independent samples t-test， while non-normally distributed continuous data were compared using the Mann-Whitney U test. Categorical data were compared between groups using the chi-square test or Fisher’s exact test. The agreement among different frailty tools was evaluated using Cohen’s Kappa statistic. The Kaplan-Meier survival curve was plotted， and a survival analysis was performed using the log-rank test. ResultsThe prevalence rate of frailty assessed by FFP， LFI， and SPPB was 37.2%， 22.4%， and 20.2%， respectively， with a moderate consistency between FFP and LFI/SPPB （κ=0.57， 95% confidence interval ［CI］： 0.47 — 0.67； κ=0.51， 95%CI： 0.41 — 0.62） and a relatively high consistency between LFI and SPPB （κ=0.87， 95%CI： 0.80 — 0.94）. Compared with the non-frailty group， the frailty group had significantly higher all-cause mortality rate and incidence rate of composite endpoints （P0.001）. After multivariate adjustment， FFP， LFI， and SPPB had a hazard ratio of 2.42（95%CI： 1.51 — 5.11）， 2.21（95%CI： 1.11 — 4.42）， and 2.21（95%CI： 1.14 — 4.30）， respectively， in predicting all-cause mortality， as well as a hazard ratio of 2.51（95%CI： 1.61 — 3.91）， 2.40（95%CI： 1.51 — 3.80）， and 2.20（95%CI： 1.39 — 3.47）， respectively， in predicting composite endpoints. Compared with Child-Pugh score， FFP had a significantly greater area under the ROC curve （AUC） in predicting all-cause mortality （0.79 vs 0.69， P=0.032） and composite endpoints （0.75 vs 0.68， P=0.044）. Frailty assessment tools combined with Child-Pugh score significantly improved the performance in predicting all-cause mortality and composite endpoints， with an AUC of 0.81 — 0.82 and 0.77 — 0.78， respectively （P0.05）. NRI and IDI analyses further confirmed the improvement of the combined model in classification （all P0.001）. ConclusionFFP， LFI， and SPPB can independently predict adverse outcomes in patients with liver cirrhosis， among which FFP has the best predictive performance， and the combination of frailty assessment tools with Child-Pugh score can significantly enhance the accuracy of prognostic evaluation.

Objective:To investigate the relationship between heart rate variability(HRV), deceleration capacity(DC) and cardiovascular metabolic disease(CMD) in children and adolescents with normal weight obesity(NWO).Methods:A total of 200 children and adolescents aged 6-17 who underwent normal physical examination in Chengdu Women′s and Children′s Central Hospital from December 2022 to June 2023 were included in this retrospective case-control study.They were divided into the NWO group, normal weight lean(NWL) group, and overweight-obesity(OW-OB) group according to their body mass index(BMI) and body fat percentage(BF%).Fifty children were enrolled into the NWO group; fifty-one children were enrolled into the NWL group; and 99 children were enrolled into the OW-OB group.All the subjects received 24-hour heart monitoring, and their HRV indexes, such as the standard deviation of N-N interval in normal sinus(SDNN), the standard deviation of the mean value N-N intervals every 5-minute(SDANN), the mean of the standard deviations of all N-N intervals for each 5-minute segment of 24 hours(SDNNindex), the root mean square of successive N-N interval difference(rMSSD), the proportion of N-N 50(the successive N-N interval differences>50 ms) in the total number of N-N intervals(pNN50), and DC were automatically calculated.Blood pressure, fasting blood glucose and blood lipids were measured, and the cardiometabolic risk score(CRS) was obtained through the accumulation of relevant factors.The general data, SDNN, SDANN, SDNNindex, rMSSD, pNN50, DC and CRS of the three groups were compared by variance analysis.Spearman correlation and multivariate Logistic regression were used to analyze the risk factors affecting CRS.Results:There was no significant difference in age, gender and other general information among the three groups(all P>0.05).SDNN in the NWO, NWL, and OW-OB groups were(120.88±16.36) ms, (129.07±16.36) ms, and(109.29±16.38) ms, respectively( F=26.231, P<0.001); SDANN were(64.44±11.61) ms, (66.25±8.34) ms, and(61.70±6.85) ms, respectively( F=5.048, P=0.007); rMSSD were(27.02±3.87) ms, (27.51±5.92) ms, and(25.12±6.78) ms, respectively( F=3.328, P=0.038); pNN50 were(12.62±4.04)%, (13.39±2.26)%, and(11.22±2.93)%, respectively( F=9.099, P<0.001); DC were(4.83±0.20) ms, (4.94±0.33) ms, and(4.63±0.28) ms, respectively( F=23.496, P<0.001)and CRS was 0.94±0.87, 0.69±0.19 and 1.57±1.07, respectively( P<0.01).The differences between the three groups were statistically significant.Spearman correlation analysis showed that BMI( r=0.211, P=0.003) and BF%( r=0.558, P<0.001) were significantly positively correlated with CRS, while SDNN( r=-0.258, P<0.001) and DC( r=-0.499, P<0.001) were significantly negatively correlated with CRS.Multivariate Logistic regression analysis showed that BF%(95% CI: 0.098-0.265, P<0.001) and DC(95% CI: -3.962--1.391, P<0.001) were independent risk factors for predicting CMD. Conclusions:Increased BF% and decreased DC are independent risk factors for CMD.Analysis of body composition and HRV in children and adolescents can help to identify potentially high-risk groups more accurately, intervene early, and reduce the risk of CMD.

Objective:To analyze the clinical, genetic mutation characteristics, and treatment prognosis of type 2A hereditary hemochromatosis (HH) in China.Methods:Peripheral blood samples and clinical data of patients with primary iron overload were collected through the China Registry of Genetic/Metabolic Liver Disease from June 2015 to November 2023. HH-related genes were detected by Sanger sequencing. Clinical characteristics and gene mutation characteristics of HH patients carrying HJV gene mutations were analyzed.Results:Among the 37 cases with primary iron overload, ten cases (27.0%, 10/37) had detectable HJV gene mutations, which included four homozygous mutations, five compound heterozygous mutations, and one monoheterozygous mutation. p.Q6H and p.C321X (80.0%, 8/10) were the most common mutated sites. The average age of onset was 30.7±14.7 years. The age of diagnosis was 35.7±16.2 years, with male-to-female ratio of 7:3. Ferritin and transferrin saturation were (5 267±905) ng/ml, and 94.3%±1.2%, respectively. Magnetic resonance imaging showed iron overload in the liver, pancreas, and myocardium. Liver biopsy showed diffuse iron deposition within hepatocytes. All ten cases had elevated transaminases; one case (1/10, 10.0%) had liver cirrhosis; four cases (4/10, 40.0%) had heart failure and arrhythmia; five cases (5/10, 50.0%) had diabetes; six cases (6/10, 60.0%) had hypogonadism; six cases (6/10, 60.0%) had skin pigmentation; and six cases (6/10, 60.0%) had fatigue symptoms. All six cases underwent bloodletting therapy, and ferritin levels dropped to about 100 ng/ml. Two cases of oral administration of the iron chelator deferasirox did not meet the ferritin level standard, and one case died from acute heart failure following a confirmed diagnosis during hospitalization.Conclusion:The HJV gene may be one of the main pathogenic genes of HH in China. The p.Q6H and p.C321X mutations were one of the hotspot mutations. The onset age of HJV gene-related HH was between 20 and 30 years old, and their condition was severe. Therefore, early bloodletting treatment can have a favorable outcome.

ObjectiveTo investigate the bactericidal effect of loaded multifunctional povidoneiodine-nanometer selenium （PVP-I@Se） disinfectant on Staphylococcus aureus （SA） and methicillin-resistant Staphylococcus aureus （MRSA）， and to provide an experimental basis for the reduction of surgical site infection （SSI）. MethodsThe control group was the povidone iodine （PVP-I） group with different concentrations of iodine （50， 75， 100， 200 and 400 μg/mL）. The PVP-I@Se group （experimental group） was the PVP-I group further supplemented with 2 μg/mL Selenium nanoparticles （SeNPs）. Then we compared the bactericidal effect of the two groups of disinfectant solutions on SA and MRSA by examining the minimum inhibitory concentration （MIC）， minimum bactericidal concentration （MBC）， the shortest sterilization time at a concentration of 50 μg/mL iodine and the inhibition zone diameters at concentrations of 200 μg/mL and 400 μg/mL iodine. ResultsMIC values of PVP-I against SA and MRSA were both 79.17 μg/mL， and those of PVP-I@Se were 54.17 and 70.83 μg/mL， respectively. MBC values of PVP-I against SA and MRSA were 129.17 and 150.00 μg/mL， respectively， and those of PVP-I@Se were 70.83 and 87.50 μg/mL， respectively. At a concentration of 50 μg/mL iodine， the shortest sterilization time of PVP-I for SA and MRSA was 130 s and 140 s， respectively， and that of PVP-I@Se was 65 s and 75 s， respectively. At a concentration of 200 μg/ml iodine， the inhibition zone diameters of PVP-I for SA and MRSA were 7.67 mm and 8.33 mm， and those of PVP-I@Se were both 9.50 mm. At a concentration of 400 μg/mL iodine， the inhibition zone diameters of PVP-I for SA and MRSA were 9.00 mm and 9.33 mm， and those of PVP-I@Se were 11.67 mm and 12.00 mm， respectively. ConclusionsPVP-I with different concentrations of 50， 75， 100， 200 and 400 μg/mL iodine supplemented with 2 μg/mL SeNPs have better and faster bactericidal effect on SA and MRSA. When combined with SeNPs， PVP-I can enhance the bactericidal activity against SA and MRSA， but with better sensitizing effect on SA than MRSA and higher demand of iodine concentration （400 μg/mL） for sensitizing effect on MRSA. This study provides a theoretical basis for selecting optimal concentration and action time of the disinfectant， thus reducing SSI.

BACKGROUND: There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden. METHODS: Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status. RESULTS: A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status. CONCLUSIONS Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.

Objective To investigate the food allergy situation of children in Changping District of Beijing,and to explore the influence of allergic family history,gender and mode of delivery on food allergy in children,the distribution of food allergy in different age groups,the types of food allergy that are easy to cause in this area,and the comorbidities of food allergy.Methods A total of 515 children aged 0 to 14 years who were admitted to the general pediatric outpatient and emergency department and inpatient of Beijing Changping Hospital from April to November 2023.Using immunoblotting to detect specific immunoglobulin E in the serum of pediatric patients,and using SPSS 26.0 statistical software to perform binomial tests on gender and delivery mode non parameters;Using custom Excel functions to statistically analyze the family history of allergies,the number of people in different age groups,and the frequency of allergic foods in each group;Use a self-made mini program to statistically analyze the combination of comorbid allergic diseases.Results ① The number of male children with food allergies(306 cases)was higher than that of female children(209 cases),and the difference was statistically significant(P＜0.05).(2)There were 109 cases of pediatric patients with parents who had no history of allergic diseases,accounting for 21.17％of the total cases;There were a total of 406 cases where at least one parent had a family history of allergies,accounting for 78.83％of the total cases.Among them,228 cases(44.27％)had one parent with a history of allergies,and 178 cases(34.56％)had both parents with a history of allergies.③ Among 515 children with positive food allergens,there were 10 cases(1.94％)in infancy,37 cases(7.19％)in early childhood,235 cases(45.63％)in preschool,192 cases(37.28％)in school age,and 41 cases(7.96％)in adolescence.The highest positivity rate for food allergens is in milk(444 times),followed by egg white(70 times),cashew nuts(57 times),crab(37 times),beef(26 times),mango(24 times),shrimp(21 times),pineapple(6 times),and shellfish(1 time).Milk protein is the most common allergen in all age groups.(4)Among 515 children with food allergies,399 cases were single food allergies,accounting for 77.47％;116 cases of multiple food allergies(2 or more types of food allergies),accounting for 22.53％.⑤ The most common comorbidity of food allergies is food allergy related gastrointestinal diseases combined with allergic rhinitis,with a total of 267 cases;Secondly,there were 192 cases of allergic rhinitis combined with chronic cough,and 124 cases of food allergy related gastrointestinal diseases combined with chronic cough.Conclusion Milk is the main allergen of food allergy in people of age 14 and under,and gastrointestinal symptoms are the most common in children with food allergy.

Objective:To combine and improve two kinds of classical transvaginal cervical cerclage,and to provide a new reference for the clinical treatment of patients with cervical insufficiency(CIC).Methods:Retro-spective analysis was performed on the clinical data of 117 patients who underwent transvaginal cervical cerclage due to CIC from January 1,2018 to August 31,2023 in the Second Affiliated Hospital of Kunming Medical Univer-sity.According to different surgical methods,the patients were divided into the modified cerclage group(40 ca-ses),the McDonald cerclage group(40 cases)and the Shirodkar cerclage group(37 cases).Intraoperative and postoperative conditions and pregnancy outcomes were compared.Univariate and multivariate Logistic regression analysis was performed to analyze the related factors of preterm birth after modified cervical cerclage and the oth-er two groups of classical cervical cerclage.Results:①Compared with the McDonald cerclage group,the modified cerclage group had longer effective cervical length,longer delivery and gestational weeks,higher term delivery rate,and shorter post-operative contraction inhibitor time,with statistical significance(P＜0.05).Compared with the Shirodkar cerclage group,the operation time of patients in the modified cerclage was significantly shortened,the amount of intraoperative blood loss was reduced,the use time of postoperative contraction inhibitors was shortened,and the rate of postoperative wire-cutting was decreased,with statistical significance(P＜0.05).②Multivariate Logistic regression analysis of preterm birth showed that the longer the length of the cervix and the later gestational age when the modified cervical cerclage was performed with reference to McDonald's cerclage,the longer the length of the cervix after surgery,the later the gestational age when the suture was removed.The risk of preterm birth was reduced(OR＜1,P＜0.05),while preoperative BMI≥24 kg/m2 was associated with an increased risk of preterm birth(OR＞1,P＜0.05).Using Shirodkar's cerclage as reference,the risk of preterm delivery was consistent between the two types of cervix(P＞0.05).Longer cervical length and later gestational age after suture removal reduced the risk of preterm delivery(OR＜1,P＜0.05).Conclusions:The modified transvaginal cervical cerclage is simple and safe in clinical application,it has certain advantages in improving ad-verse pregnancy outcomes of pregnant women,which provides a new reference for the treatment of pregnant women with CIC.Due to the small number of cases included in the study,comprehensive evaluation by clinicians is still needed for clinical application.

AIM:To investigate the therapeutic effect of mitochondrial fission inhibitor-1(Mdivi-1)on experi-mental autoimmune encephalomyelitis(EAE)in mice,and to explore its mechanism.METHODS:The mice immunized with myelin oligodendrocyte glycoprotein peptide fragment 35-55(MOG35-55)were randomly divided into DMSO model group and Mdivi-1 intervention group.All mice were sacrificed on the 28th day after the first immunization.The demyelination was analyzed by Luxol fast blue staining.The protective mechanism of Mdivi-1 in the spinal cord tissue was investigated by immunofluorescence staining,TUNEL staining and the in vitro experiment with MO3.13 oligodendrocytes treated with staurosporine.The mitochondrial depolarization was detected by JC-1 staining,the cell injury was checked by LDH leakage,and the viability of MO3.13 oligodendrocytes was determined by MTT assay.RESULTS:Compared with DMSO model group,the demyelinating injury was alleviated and the proportion of apoptotic CC1+ oligodendrocytes in Mdivi-1 group was decreased.The cleaved caspase-3,caspase-9,cytochrome C and Bax protein expression levels in the spinal cord of Mdivi-1-treated mice was also attenuated.The in vitro MO3.13 cell experiments suggested that Mdivi-1 inhibited MO3.13 cell mitochondrial depolarization,attenuated the cell damage and increased the cell viability.CONCLUSION:Mdivi-1 pro-tects against the myelin injury in EAE mice,which may be related to the suppression of oligodendrocyte apoptosis.
