ABSTRACT
Objective:To study the prognosis of congenital bile duct cysts following cyst resection, and to analyze the risk factors associated with the development of postoperative biliary calculus.Methods:Clinical data of 149 patients with congenital bile duct cysts undergoing surgery in the First Affiliated Hospital of Nanjing Medical University from May 2004 to January 2022 were retrospectively analyzed, including 59 males and 90 females, with a median age of 32 (21, 47) years old. Patients were divided into two groups: the stone group ( n=51, biliary calculus occurred during the follow-ups after surgery) and non-stone group ( n=98). Clinical data such as gender, age, medical history, cyst type, biliary calculus, anastomotic stenosis and occurrence of cancer were compared. All patients were followed up via telephone consultations. A logistic regression analysis was used to identify the risk factors associated with the occurrence of biliary calculus after surgery. Results:The duration of the follow-ups was 120 (24, 211) months. The observed incidence of postoperative biliary calculus, anastomotic stricture, and cancer in the patients were 34.2% (51/149), 8.7% (13/149), and 4.7% (7/149), respectively. The logistic regression analysis indicated that incomplete cyst resection ( OR=3.332, 95% CI: 1.221-9.094) and postoperative anastomotic stenosis ( OR=13.300, 95% CI: 2.586-68.401) were associated with a higher risk of biliary calculus formation after cystectomy (all P<0.05). Conclusion:Patients with congenital bile duct cysts suffer a high risk of biliary calculus formation after cystectomy. The residual cyst and postoperative anastomotic stenosis are independent risk factors for biliary calculus after surgery.
ABSTRACT
Objective:To analyze the clinical application value of a novel magnetic navigation ultrasound (MNU) combined with digital subtraction angiography (DSA) dual-guided percutaneous transhepatic biliary drainage (PTCD) through the right hepatic duct for the treatment of malignant obstructive jaundice.Methods:Randomized controlled trial. The clinical data of 64 patients with malignant obstructive jaundice requiring PTCD through the right hepatic duct at the Hepatobiliary Center of the First Affiliated Hospital of Nanjing Medical University (Jiangsu Province People′s Hospital) from December 2018 to December 2021 were retrospectively analyzed. The MNU group ( n=32) underwent puncture guided by a novel domestic MNU combined with DSA, and the control group ( n=32) underwent puncture guided by traditional DSA. The operation time, number of punctures, X-ray dose after biliary stenting as shown by DSA, patients' tolerance of the operation, success rate of the operation, pre- and post-operative total bilirubin, and incidence of postoperative complications were compared between the two groups. Results:The operation time of the MNU group was significantly shorter than that of the control group [(17.8±7.3) vs. (31.6±9.9) min, t=-6.35, P=0.001]; the number of punctures in the MNU group was significantly lower [(1.7±0.6) vs. (6.3±3.9) times, t=-6.59, P=0.001]; and the X-ray dose after biliary stenting as shown by DSA in the MNU group was lower than that in the control group [(132±88) vs. (746±187) mGy, t=-16.81, P<0.001]; Five patients in the control group were unable to tolerate the operation, and two stopped the operation, however all patients in the MNU group could tolerate the operation, and all completed the operation, with a success rate of 100% (32/32) in the MNU group compared to 93.8%(30/32) in the control group; the common complications of PTCD were biliary bleeding and infection, and the incidence of biliary bleeding (25.0%, 8/32) and infection (18.8%, 6/32) in the MNU group was significantly lower than that in the control group, 53.1% (17/32) and 28.1% (9/32), respectively. Conclusion:Magnetic navigation ultrasound combined with DSA dual-guided PTCD through the right biliary system for the treatment of malignant obstructive jaundice is safe and feasible.
ABSTRACT
Background The Qingcaosha Reservoir is facing issues of algal blooms and eutrophication, and the resulting increase in the level of chlorination disinfection by-products in the water has been a major concern. Objective To evaluate the impact of "Algae Monitoring and Control Program in Qingcaosha Reservoir" (hereinafter referred to as the program) on the control of trihalomethanes (THMs) in conventional finished water. Methods From 2011 to 2019, water samples were collected from the Lujiazui Water Plant once per season, one sample each time, and the concentrations of four THMs (trichloromethane, dichlorobromomethane, monochlorodibromomethane, and tribromomethane) were measured in the samples. Using 2014 when the program was implemented as a cut-off point, the entire study period was divided into two phases: pre-implementation (2011–2013) and post-implementation(2014–2019). Segmented linear regression with interrupted time series analysis was applied to assess the concentrations and trends of THMs in the finished water before and after the program launch. Results The concentration of total THMs in finished water increased by 1.561 µg·L−1 (P=0.010) for each season of time extension before launching the program. The change in the concentration of total THMs in finished water was not statistically significant after the program launch, but the THMs concentration showed a decreasing trend as the slope was −0.626 (P=0.001). From 2017 until the end of 2019, the average concentration of THMs in finished water of Lujiazui Water Plant dropped to 10 μg·L−1 or less. Conclusions The algae and eutrophication control measures in Qingcaosha Reservoir have achieved good results, controlling THMs in finished water at a low level, and the trend of THMs has changed from a yearly increase pattern before the program to a yearly decrease pattern after the program.

This article provides a review of the urgent need for healthcare professionals to focus on the current status, adverse outcomes, screening and management aspects of diabetes after acute pancreatitis, and aims to provide a reference for healthcare professionals in their relevant clinical work.
ABSTRACT
Objective: To evaluate the efficacy and influencing factors of programmed death protein 1 (PD-1) monoclonal antibody rechallenge therapy in advanced gastric cancer (GC). Methods: The clinical data of patients with advanced GC who were treated with anti-PD-1 rechallenge in Henan Cancer Hospital from January 2020 to December 2021 were collected retrospectively. The progression-free survival (PFS) was defined as the time from the first or second used of anti-PD-1 treatment to the date of disease progression or the last follow-up, named PFS(1) and PFS(2), respectively. Kaplan-Meier method and Log rank test were used for survival analysis, Cox proportional hazard model was used to analyze the influencing factors. Results: A total of 60 patients with anti-PD-1 rechallenge therapy were collected, the median follow-up time was 12.2 months. The median progression-free survival (PFS(2)) of anti-PD-1 rechallenge therapy was 2.9 months, the objective response rate (ORR) was 16.7%, and the disease control rate (DCR) was 55.0%. The median PFS(2) of the first and second anti-PD-1 identical and different rechallenge treatment was 3.5 months and 1.9 months (P=0.007) respectively. The median PFS(2) of positive PD-L1 expression in rechallenge therapy was 3.4 months, ORR was 22.7%, and DCR was 63.6%; the median PFS(2) was 4.5 months, ORR was 27.3%, and DCR was 54.5% in patients with median PFS(1)≥6 months. Multivariate analysis showed that peritoneal metastasis was independently associated with anti-PD-1 rechallenge therapy with PFS(2) (HR=2.327, 95% CI, 1.066-5.082, P=0.034). The incidence of adverse reactions in grade 1-2 and grade 3-4 of anti-PD-1 rechallenge therapy was 83.3%, and 35.0%, respectively, and the safety was controllable. Conclusion: Rechallenge therapy with anti-PD-1 is a feasible treatment in advanced GC, but the screening of suitable population for rechallenge therapy still needs prospective data analysis and verification.

Background@#Although an inverse association between the N-terminal prohormone brain natriuretic peptide (NT-proBNP) and obesity exists, only few major studies have assessed the association between NT-proBNP levels and skeletal muscle mass in asymptomatic healthy adults. Therefore, this cross-sectional study was conducted. @*Methods@#We assessed participants who underwent health examinations at Kangbuk Samsung Hospital in South Korea from January 2012 to December 2019. Appendicular skeletal muscle mass was measured using a bioelectrical impedance analyzer, and the skeletal muscle mass index (SMI) was calculated. Participants were divided into the control, mildly low skeletal muscle mass (LMM) (−2 standard deviation [SD] < SMI ≤−1 [SD]), and severely LMM groups (SD ≤−2) based on their SMI. The association between elevated NT-proBNP level (≥125 pg/mL) and skeletal muscle mass was assessed using multivariable logistic regression analysis with adjustment for confounding factors. @*Results@#This study enrolled 15,013 participants (mean age, 37.52±9.52; men, 54.24%; control, n=12,827; mildly LMM, n=1,998; severely LMM, n=188). Prevalence of elevated NT-proBNP was higher in mildly and severely LMM groups than in the control group (control, 1.19%; mildly LMM, 1.4%; severely LMM, 4.26%; P=0.001). The adjusted odds ratio (OR) of elevated NT-proBNP was significantly higher in severely LMM (OR, 2.87; 95% confidence interval [CI], 1.3 to 6.37) than in control (OR, 1.00; reference) or mildly LMM groups (OR, 1.24; 95% CI, 0.81 to 1.89). @*Conclusion@#Our results showed that NT-proBNP elevation were more prevalent in participants with LMM. In addition, our study showed an association between skeletal muscle mass and NT-proBNP level in a relatively young and healthy adult population.
ABSTRACT
Objective: To characterize the relationship between the levels of plasma methyl donor and related metabolites (including choline, betaine, methionine, dimethylglycine and homocysteine) and fetal growth in twin pregnancies. Methods: A hospital-based cohort study was used to collect clinical data of 92 pregnant women with twin pregnancies and their fetuses who were admitted to Peking University Third Hospital from March 2017 to January 2018. Fasting blood was collected from the pregnant women with twin pregnancies (median gestational age: 18.9 weeks). The levels of methyl donors and related metabolites in plasma were quantitatively analyzed by high-performance liquid chromatography combined with mass spectrometry. The generalized estimation equation was used to analyze the relationship between maternal plasma methyl donors and related metabolites levels and neonatal outcomes of twins, and the generalized additive mixed model was used to analyze the relationship between maternal plasma methyl donors and related metabolites levels and fetal growth ultrasound indicators. Results: (1) General clinical data: of the 92 women with twin pregnancies, 66 cases (72%) were dichorionic diamniotic (DCDA) twin pregnancies, and 26 cases (28%) were monochorionic diamniotic (MCDA) twin pregnancies. The comparison of the levels of five plasma methyl donors and related metabolites in twin pregnancies with different basic characteristics showed that the median levels of plasma choline and betaine in pregnant women ≥35 years old were higher than those in pregnant women <35 years old, and the differences were statistically significant (all P<0.05). (2) Correlation between plasma methyl donor and related metabolites levels and neonatal growth indicators: after adjusting for confounding factors, plasma homocysteine level in pregnant women with twins was significantly negatively correlated with neonatal birth weight (β=-47.9, 95%CI:-94.3- -1.6; P=0.043). Elevated methionine level was significantly associated with decreased risks of small for gestational age infants (SGA; OR=0.5, 95%CI: 0.3-0.9; P=0.021) and low birth weight infants (OR=0.6, 95%CI: 0.4-0.9; P=0.020). Increased homocysteine level was associated with increased risks of SGA (OR=1.5, 95%CI: 1.0-2.2; P=0.029) and inconsistent growth in twin fetuses (OR=1.9, 95%CI: 1.0-3.7; P=0.049). (3) Correlation between the levels of plasma methyl donors and related metabolites and intrauterine growth indicators of twins pregnancies: for every 1 standard deviation increase in plasma choline level in pregnant women with twin pregnancies, fetal head circumference, abdominal circumference, femoral length and estimated fetal weight in the second trimester increased by 1.9 mm, 2.6 mm, 0.5 mm and 20.1 g, respectively, and biparietal diameter, abdominal circumference and estimated fetal weight increased by 0.7 mm, 3.0 mm and 38.4 g in the third trimester, respectively, and the differences were statistically significant (all P<0.05). (4) Relationship between plasma methyl donor and related metabolites levels in pregnant women with different chorionicity and neonatal birth weight and length: the negative correlation between plasma homocysteine level and neonatal birth weight was mainly found in DCDA twin pregnancy (β=-65.9, 95%CI:-110.6- -21.1; P=0.004). The levels of choline, betaine and dimethylglycine in plasma of MCDA twin pregnancy were significantly correlated with the birth weight and length of newborns (all P<0.05). Conclusion: Homocysteine level is associated with low birth weight in twins, methionine is associated with decreased risk of SGA, and choline is associated with fetal growth in the second and third trimesters of pregnancy.

@#Abstract: Objective To analyze the epidemiological characteristics of viral hepatitis E in Fujian Province from 2012-2021, and to provide scientific evidence for the prevention and control of hepatitis E in the future. Methods Descriptive epidemiological method was used to analyze hepatitis E cases in Fujian Province from 2012 to 2021. Results From 2012 to 2021, a total of 8 877 cases of hepatitis E were reported in Fujian Province from 2012-2021. The overall incidence rate showed a decreasing trend (χ2trend =458.14, P<0.001), with the lowest incidence rate of 1.32/100 000 in 2020 and an annual average incidence rate of 2.29/100 000 per year. The incidence was higher in winter and spring, with the months of March and April having the highest number of reported cases (2 146, 24.17%) and the fewest cases were reported in September (571, 6.43%). The difference in reported incidence rates between cities was statistically significant (χ2=1 877.75, P<0.01). The comprehensive experimental zone of Pingtan had the highest average reported incidence rate of 6.03/100 000, while Zhangzhou had the lowest at 0.94/100 000. The number of male cases was higher than the number of female cases, with a male to female ratio of 2.04∶1. The disease was most prevalent among middle-aged and elderly individuals, with the age group of 40-<65 years having the highest number of reported cases, accounting for 57.44% (5 099/8 877) of all cases. The age group of 50-<55 years had the highest reported incidence, with the number of reported cases increasing with age below 50 years, but decreasing with age over 50 years. As for occupational distribution, peasants had the highest proportion of the disease, accounting for 34.49% (3 062 cases) of the total cases. Conclusions The reported incidence rate of hepatitis E in Fujian showed a downward from 2012 to 2021. Due to the impact of COVID-19, incidence of the lowest was 2020, but it did not reflect the true situation of the disease, which may have affected trend of hepatitis E. In order to control and reduce the incidence of hepatitis E, efforts should be made to increase publicity and education on health knowledge and vaccination among key areas and populations, strengthen monitoring and diagnostic capability, and implement comprehensive prevention and control measures.

ABSTRACT
Background Non-occupational carbon monoxide (CO) poisoning is a public health problem that seriously affect people’s health and lives. Objective To describe the prevalence of non-occupational CO poisoning during 2007—2018 in Shanghai, analyze its epidemiological characteristics and potential influencing factors, and explore effective prevention and control measures. Methods Daily reported non-occupational CO poisoning cases and meteorological factors from 2007 to 2018 were collected in Shanghai, epidemiological characteristics were analyzed by descriptive epidemiology methods, and a distributed lag nonlinear model was used to assess the association between temperature and non-occupational CO poisoning. Results A total of 2264 non-occupational CO poisoning events and 3866 cases from 2007 to 2018 were reported in Shanghai, including 59 death cases. More than half of the poisoning cases were female (56.3%), and young adults accounted for more cases than any other age group (54.8%). The poisoning events mainly occurred in winter (from December to next February); however, cases reported in summer increased in recent years. The peak period of the events was from 20:00 to 24:00. Households (85.2%) and restaurants (8.0%) were the common places of non-occupational CO poisoning events, and the main cause was improper use of gas water heater (36.9%). A nonlinear curve was found between daily average temperature of current day and the occurrence of non-occupational CO poisoning. Temperature was negatively associated with the risk of non-occupational CO poisoning when the temperature was lower than 9.6 ℃, while a positive association was found during 9.7-26.0 ℃. Conclusion Winter is a high season for non-occupational CO poisoning in Shanghai, rising cases reported in summer is also worthy of attention. Supervision should be strengthened to ban sales of unqualified gas water heaters, and health education on CO poisoning prevention and control should be conducted through multiple channels, in order to reduce the incidence of CO poisoning.
ABSTRACT
Objective:To study the clinical application of a new classification on location of hepatolithiasis in guiding treatment using percutaneous transhepatic choledochoscopic lithotomy (PTCSL).Methods:The clinical data of 85 consecutive patients with preoperatively diagnosed hepatolithiasis who underwent PTCSL at the First Affiliated Hospital of Nanjing Medical University from January 2017 to July 2021 were prospectively collected. There were 27 males and 58 females, aged from 15 to 86(62±14) years. Hepatolithiasis was classified into five types of stone location based on preoperative imagings: type Ⅰ ( n=12) , stones located in central bile duct, including hilar bile duct and common hepatic duct; type Ⅱ ( n=17) in unilateral hepatic duct with multiple branches; type Ⅲ ( n=24) in unilateral hepatic duct with multiple branches plus central bile duct; type Ⅳ ( n=31) in bilateral hepatic ducts with multiple branches; and type Ⅴ ( n=1) in unilateral hepatic duct with a single branch. Fistulation path, number of procedures, number of bile duct fistula, and complications were recorded. The residual stone rate and stone recurrence rate were compared among the five types. The follow-up was performed to analyse prognosis. Results:A total of 99 biliary fistulae were performed, with one single tract created in 74 patients, two tracts in 9 patients, three tracts in 1 patient, and four tracts in 1 patient. The fistulation path was B2 in 12 patients, B3 in 18 patients, B4 in 1 patient, B5 in 4 patients, B6 in 10 patients, B7 in 4 patients, and B8 in 50 patients. Altogether, 151 choledochoscopic lithotomy procedures were performed (1-3 times per patient, mean 1.78 times). For the 9 patients with residual stones (10.6%, 9/85), there were 3 patients with type Ⅱ and 6 patients with type Ⅳ. There were significant differences in the residual stone rates among the 5 types (χ 2=11.13, P=0.025). Stone recurrence developed in 33 (38.8%) patients, including 2 patients with type Ⅰ, 7 patients with type Ⅱ, 10 patients with type Ⅲ and 14 patients with type Ⅳ (χ 2=9.07, P=0.046). The total intraoperative and postoperative complications rates was 28.2% (24/85). The follow-up period was 4-58 months with the median follow-up time of 30 months. Twelve patients died during the follow-up period, including 1 patient who died from postoperative bleeding, 3 cholangiocarcinoma, 7 biliary cirrhosis-related liver failure, and 1 stone-unrelated disease. Conclusion:Type Ⅳ in the location classification of hepatolithiasis based on PTCSL had significantly higher rates of residual stones and stone recurrence. This new classification is helpful for clinicaians to determine the optimal path using a smaller number of fistulation tracts to clear stones. It improved the efficacy of PTCSL in treating hepatolithiasis.
ABSTRACT
Objective:To investigate the effect of miR-485-5p on cisplatin resistance of colon cancer cells through the PI3K/Akt-PAK1 signaling pathway.Methods:The LoVo/DDP cell lines were constructedand divided into an NC group(without transfection treatment), an miR-485-5p mimics group(transfected with miR-485-5p mimics), an miR-485-5p inhibitors group(transfected with miR-485-5p inhibitors), an IPA-3 group(intervention with IPA-3)and an miR-485-5p mimics+ IPA-3 group(transfection with miR-485-5p mimics andinterventionwith IPA-3), with all given 0, 3, and 5 μmol/L cisplatin treatment.Results:Among the 20 patients, the proportion of negative miR-485-5p detection was 85.0%(17/20), and the proportion of positive detection was 15.0%(3/20); the proportion of negative PAK1 detection was 20.0%(4/20), and the proportion of positive detection was 80.0%(16/20). The expression of miR-485-5p in colon cancer tissue was significantly lower than that in adjacent tissues( P<0.05); the expression of miR-485-5p in the human colon cancer cell lines LoVo, SW620, HCT116, and SW480 was all lower than in normal intestinal mucosal cells( P<0.05); the expression of miR-485-5p in LoVo/DDP was significantly lower than inLoVo( P<0.001). Under the action of 3 μmol/L and 5 μmol/L cisplatin, LoVo/DDP had highercell viability but a lower apoptosis rate than LoVo( P<0.001). The cell survival rate in the miR-485-5p mimics group was significantly lower than that in the miR-485-5p inhibitors group( P<0.001). Compared with the NC mimics group, overexpression of miR-485-5p significantly down-regulated luciferase activity of the wild-type PAK1 reporter gene( P<0.001); P-PI3k, P-Akt and PAK1levels in the miR-485-5p mimics group were significantly lower than in the miR-485-5p inhibitors group( P<0.001); the cell survival rate in the miR-485-5p mimics group, the IPA-3 group and the miR-485-5p mimics+ IPA-3 group was significantly lower than in the NC group( P<0.001)and the cell survival rate in the miR-485-5p mimics+ IPA-3 group was significantly lower than in the miR-485-5p mimics group( P<0.001). Conclusions:Up-regulation of miR-485-5p reverses colon cancer cisplatin resistance through the PI3K/Akt-PAK1signaling pathway, suggesting that overexpression of miR-485-5p or inhibition of the PI3K/Akt-PAK1signaling pathway enhances the therapeutic efficacy of cisplatin in colon cancer.
ABSTRACT
Objective: To investigate the clinicopathological features and differential diagnoses of paratesticular liposarcoma. Methods: The cases were collected from 2012-2020, from the archives of the Department of Pathology, Peking University Third Hospital, with diagnosis confirmed by histology, immunostaining and FISH tests. Results: Totally 19 patients were enrolled (including 11 in-hospital patients and 8 consultant cases). The patients aged 37-84 years (mean 57 years). The preoperative clinical diagnoses were spermatic cord/inguinal masses (nine patients), scrotal masses (seven patients), and inguinal hernia (three patients). Six lesions recurred after local resection, including one case extending from pelvic liposarcoma. Histologically, there were 10 cases of well-differentiated liposarcoma (WDLPS) and nine cases of dedifferentiated liposarcoma (DDLPS). WDLPSs mostly showed the combined features of lipoma-like, inflammatory and sclerosing subtypes (six patients); the other four WDLPSs had pure lipoma-like subtype features. DDLPSs were low-grade (three patients) or high-grade (six patients), with the morphology resembling myxofibrosarcoma, inflammatory myofibroblastoma, spindle cell sarcoma, pleomorphic undifferentiated sarcoma and pleomorphic liposarcoma. Intense inflammatory cells infiltration was commonly observed in five WDLPSs and two DDLPSs. Ossification was observed in three tumors. Immunohistochemically, the tumors were positive for MDM2 (8/10) and CDK4 (10/10), which were expressed in lipo-differentiating cells, spindle cells in WDLPS, and in dediffferentiated components. S-100 was only expressed by lipocytes (10/10). CD34 expression was positive and diffuse in the stromal cells of WDLPSs and focal or diffuse in dedifferentiated areas (10/10). FISH tests with an MDM2 gene probe were positive (12/12). Conclusions: Paratesticular liposarcoma may be overlooked by both clinicians and pathologists. WDLPS and DDLPS predominate, showing various histologic divergences. The presence of amplification of the 12q14-q15 region (containing the MDM2 and CDK4 genes) is helpful for making the correct diagnosis.

ABSTRACT
@#AIM: To investigate the efficiency and safety of 3D visualization assisted phacoemulsification combined with intraocular lens(IOL)implantation. METHODS: Prospective non-randomized controlled clinical study. A total of 100 patients(103 eyes)who underwent phacoemulsification combined with IOL implantation were enrolled in the study. Among them, according to the way of surgery chosen by the participants, 24 cases(25 eyes)were enrolled from January to March 2020(3D-1 group), 24 cases(25 eyes)were enrolled from April to June 2020(3D-2 group), and 52 cases(53 eyes)were enrolled from January to June 2020(binocular microscope group)as the control group. Total operative time, capsulorhexis time, phacoemulsification operation time, cortical aspiration time, IOL implantation time, viscoelastic agent aspiration time, ultrasound time(UST), cumulative dissipated energy(CDE), fluid flow loss, intraoperative and postoperative complications were recorded in the three groups. Uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), intraocular pressure(IOP)and corneal endothelial cell count(CECC)were recorded preoperatively and 1mo postoperatively. RESULTS: The total operative time, the time of capsulorhysis, the operation time of phacoemulsification, and the time of removing viscoelastic agent between 3D-1 group and control group were statistically significant(all <i>P</i><0.01). There were no significant differences in the total operation time and each operation step time between the 3D-2 group and the control group(all <i>P</i>>0.05). The differences of UST, liquid flow loss, and CDE between 3D-1 group and the control group were statistically significant(all <i>P</i><0.05). There were no significant differences between the 3D-2 group and the control group in intraoperative parameters(all <i>P</i>>0.05). There were no statistical significances in UCVA, BCVA, IOP, and CECC among the three groups 1mo after surgery(all <i>P</i>>0.05). CONCLUSION: Phacoemulsification combined with IOL implantation using 3D visualization technology is safe and feasible. After a certain learning curve period, there is no significant difference in the surgical efficiency compared with traditional binocular surgery.
ABSTRACT
Objective@#To establish a prediction model of herpangina epidemic trend based on Baidu index and hand, foot and mouth disease, so as to provide insights into analyses of communicable disease epidemics with limited or missing surveillance data.@*Methods@#The incidence of hand, foot and mouth disease in Zhejiang Province during the period from the first week of 2015 through the 39th week of 2021 was retrieved from the China Information System for Disease Control and Prevention, and the Baidu index of hand, foot and mouth disease and herpangina was collected via the Baidu search engine during the same period. The correlation between the Baidu index and time series of hand, foot and mouth disease was examined using wavelet analysis. In addition, a random forest training model was created based on the Baidu index and incidence of hand, foot and mouth disease, and the fitting effectiveness was evaluated using the mean percentage error, while the Baidu index of herpangina was included in the model to predict the epidemic trend of herpangina during the study period.@*Results@#The Baidu index of herpangina and hand, foot and mouth disease, and the Baidu index and incidence of hand, foot and mouth disease all appeared two peaks at the 26th and 52th week. The phase difference was less than 0.1 week between the Baidu index and time series of hand, foot and mouth disease, and the mean percentage error of the training model was 13.07%, with high concordance between the predicted number and actual report number of cases with hand, foot and mouth disease. The numbers of herpangina cases were predicted to be 28 822, 27 341, 28 422, 51 782, 52 457 and 5 691 from 2015 to 2020, and there were totally 48 702 herpangina cases reported until the 39th week of 2021. Like hand, foot and mouth disease, the incidence of herpangina peaked between May and July.@*Conclusion@#The random forest training model based on the Baidu index and incidence of hand, foot and mouth disease is feasible to predict the epidemic trend of herpangina.
ABSTRACT
Objective@#To investigate the epidemiological features of notifiable infectious diseases in Zhejiang Province in 2021, so as to provide the evidence for formulating infectious disease control measures.@*Methods@#The data pertaining to notifiable infectious diseases reported in Zhejiang Province in 2021 were retrieved from the Infectious Disease Surveillance System of China Information System for Disease Control and Prevention. The incidence and mortality of notifiable infectious diseases in Zhejiang Province in 2021 were descriptively analyzed.@*Results@#Totally 29 types of notifiable infectious diseases with 396 623 cases and 391 deaths were reported in Zhejiang Province in 2021, with a reported incidence of 614.28/105 and a reported mortality of 0.605 6/105, respectively. There were 93 204 cases with class B notifiable infectious diseases, with a reported incidence rate of 144.35/105 and 303 419 cases with class C notifiable infectious diseases, with a reported incidence rate of 469.92/105; while no cases with class A notifiable infectious diseases were reported. Syphilis (39.45/105), tuberculosis (37.12/105), viral hepatitis (31.90/105) and gonorrhea (26.34/105) were the four most common class B notifiable infectious diseases, and AIDS (0.477 0/105) and pulmonary tuberculosis (0.116 2/105) were the two most deadly class B notifiable infectious diseases, while hand, foot and mouth disease (192.00/105), other infectious diarrhea (184.24/105) and influenza (86.45/105) were the three most common class C notifiable infectious diseases. According to the transmission route, intestinal and respiratory infectious diseases were the two most common infectious diseases, with reported incidence rates of 384.10/105 and 133.73/105, respectively; and according to the reported region, the highest incidence of class B notifiable infectious diseases was reported in Zhoushan and Ningbo cities, and the highest incidence of class C notifiable infectious diseases was reported in Ningbo City. Totally 1 101 COVID-19 cases were reported in Zhejiang Province in 2021, including 712 confirmed cases and 389 asymptomatic cases, and no deaths occurred.@*Conclusions@#The reported incidence of notifiable infectious diseases declined in Zhejiang Province in 2021 as compared to that prior to COVID-19 epidemics, with remarkable reductions in the incidence of respiratory and intestinal infectious diseases. The management of pulmonary tuberculosis, viral hepatitis and AIDS requires to be reinforced during the containment of COVID-19, to prevent the seasonable epidemic of influenza, hand, foot and mouth disease and other infectious diarrhea in Zhejiang Province.
ABSTRACT
Objective:To explore the mediating effect of caring ability of family caregivers on dementia patients′ self-care ability and family caregiver burden.Methods:A total of 113 dementia caregivers of dementia patients recruited in Shandong Provincial Hospital Affiliated to Shandong First Medical University and Shandong Mental Health Center from September 2020 to January 2021 were selected, and the Barthel Index, Family Caregiver Task Inventory and Zarit Burden Interview were used to capture their responses on dementia patients′ self-care ability, caring ability, and caregiver burden.Results:The score of self-care ability of dementia patients was (75.19 ± 28.56), and scores of caring ability and care burden of caregivers were 9.00(4.00, 15.00) and (33.78 ± 16.53), respectively. The self-care ability of dementia patients was negatively associated with caring ability and care burden of caregivers ( r=-0.424, -0.420, both P<0.01), and the caring ability and care burden were positively correlated ( r=0.605, P<0.01). The intermediary effect of dementia caregivers' caring ability between patients' self-care ability and caregivers' care burden is significant. The indirect effect was -0.107 and the total effect was -0.187. The indirect effect accounted for 57.22% of the total effect. Conclusions:Caring ability of family caregivers mediates the relationship between self-care ability of dementia patients and caregivers' care burden.The caring ability may be used as an intervening target for future studies.
ABSTRACT
Aim To investigate the effect of circRNA- 32011 on myocardial apoptosis induced by arsenic triox- ide (ATO).Methods Primary cardioniyocytes of suckling neonate mouse were treated with ATO ( final concentration 10 (xniol • L_1 ) for 24 h.Then cell via¬bility was measured by M IT assay.The mKNA expres¬sion levels of Bel-2/ Bax and circRNA-3201 I were de¬tected by KT-PCK.Bcl-2/Bax protein expression lev¬els were detected by Western blot.Overexpression and knock down circHNA-32011 respectively by plasmid and siHNA were used to verify its function in ATO-in- duced cardiomyocyte apoptosis.Results Myocardial cell viability decreased, Bel-2 expression significantly decreased while Bax expression increased in ATO group compared with the control group.CircKNA- 32011 was down-regulated in ATO ineuhated cardio¬niyocytes.Ovcrex press ion of circRNA-32011 in ATO- incubated cardioniyocytes increased myocardial cell vi¬ability and Bel-2 expression and decreased the expres¬sion of Bax.Knockdown of circRNA-32011 could fur¬ther reduce cardiomyoevte activity and Bel-2 expression and increase the experssion of Bax induced by ATO.Conclusions CircRNA-32011 protects cardiac myo¬cytes from apoptosis induced by arsenic trioxide, which may provide a new potential therapeutic strategy for ATO-induced myocardial injury.
