Objective: To investigate the awareness of knowledge about hepatitis C prevention and control among outpatients in Ningbo City, Zhejiang Province, and its influencing factors, so as to provide the evidence for strengthening health education on hepatitis C prevention and control. Methods: Based on sentinel surveillance of hepatitis C, the outpatients aged 15 to 65 years at seven hospitals in Yinzhou District, Cixi City and Xiangshan County of Ningbo City were selected using the convenient sampling method from April to June during 2020 and 2022. Demographic information, knowledge and behaviors related to hepatitis C prevention and control were collected through questionnaire surveys. The influencing factors for knowledge about hepatitis C prevention and control were analyzed using a multivariable logistic regression model. Results: A total of 2 792 participants were surveyed, including 1 157 males (41.44%) and 1 635 females (58.56%). The awareness rate of knowledge about hepatitis C prevention and control was 56.23%, and was lower in knowledge about hepatitis C vaccine and treatment. The awareness rates of knowledge about hepatitis C prevention and control among outpatients from 2020 to 2022 were 47.11%, 53.22% and 70.65%, respectively, showing an upward trend (P<0.05). Multivariable logistic regression analysis showed that participants aged 25 to <50 years (OR=1.358, 95%CI: 1.073-1.719), with an educational level of high school or junior college (OR=1.431, 95%CI: 1.134-1.806) or above junior college (OR=3.728, 95%CI: 2.958-4.699), with household monthly income per capita of 3 000 to <5 000 yuan (OR=1.828, 95%CI: 1.344-2.486) or ≥5 000 yuan (OR=1.858, 95%CI: 1.366-2.526), without a history of invasive treatments such as pedicure in public places (OR=1.287, 95%CI: 1.024-1.618), without a history of contact with family members' blood-contaminated items (OR=2.050, 95%CI: 1.552-2.707), and always using condoms during sexual contacts (OR=1.740, 95%CI: 1.273-2.378) had higher awareness of knowledge about hepatitis C prevention and control. Conclusions The awareness of knowledge about hepatitis C vaccine and treatment among outpatients in Ningbo City needs to be improved. Age, educational level, household monthly income per capita, history of invasive treatments such as pedicure in public places, history of contact with family members' blood-contaminated items and frequency of condom use during sexual contacts are associated with outpatients' awareness of knowledge about hepatitis C prevention and control.

Objective To analyze the influence of drainage volume on prognosis of acute hydrocephalus(AHC)after aneurysmal subarachnoid hemorrhage(aSAH)by continuous lumbar drainage.Methods A retrospective trial was conducted on 82 AHC patients after aSAH admitted to the First Affiliated Hospital of Chongqing Medical University between January 2017 and January 2022.In 6 months after discharge,modified Rankin Scale(mRS)score was used to evaluate the prognostic outcomes.Univariate and multivariate logistic regression analyses were performed on demographic factors,severity of subarachnoid hemorrhage(SAH)at admission,medical history,cerebral vasospasm,and lumbar drainage data.Then a nomogram prediction model was constructed.Results Univariate analysis found that World Federation of Neurosurgical Societies(WFNS)score,Hunt-Hess grade,modified Fisher grade,time for continuous lumbar drainage,shunt dependence,cerebral vasospasm,and drainage volume were factors affecting the prognosis of the patients.Then logistic regression analysis revealed that high WFNS score(OR:3.25,95％CI:1.11～9.48),high modified Fisher grade(OR:3.66,95％CI:1.08～12.35),shunt dependence(OR:15.56,95％CI:1.22～198.57),and cerebral vasospasm(OR:22.24,95％CI:3.08～160.68)were independent predictors for mRS score,while volume of continuous lumbar drainage(OR:0.57,95％CI:0.40～0.82)was an independent protective factor.ROC curve analysis indicated a good predictive performance of the model(AUC=0.898,95％CI:0.935～0.861).Internal validation through Bootstrap method demonstrated excellent discriminatory ability of the model(C-index=0.950,95％CI:0.904～0.996;adjusted C-index:0.934).Conclusion Increased volume of lumbar drainage is an independent protective factor for poor prognosis following aSAH and can improve the prognosis of SAH patients.

Objective To explore the risk factors of supplementary injection after foam sclerotherapy for varicose veins of lower extremities and its impact on blood coagulation function.Methods A total of 185 patients with varicose veins of lower limbs diagnosed in the First People's Hospital of Zunyi from January 2018 to December 2021 were selected.The corresponding pathological data were collected,and the D-dimer,thrombin time,and fibrinogen level of patients were detected 1 d before and 1 d after the surgery.The postoperative video phone follow-up lasted until 6 months after the surgery.The patients were divided into single treatment group and supple-mentary treatment group according to whether supplementary injection of foam sclerosing agent was needed during the follow-up.Propensity matching on the data between the two groups was conducted,and the correlation between disease course data,coagulation factors,and the occurrence of supplementary injection was analyzed.A time series model for the incidence of supplementary injection was established,and the therapeutic effect and complica-tions were observed.Results After propensity matching,there was still significant difference in the degree of lesion between the two groups(P<0.05).On the first day after surgery,there was significant difference in the D-dimer and fibrinogen groups between the two groups(P<0.05),and but no significant difference in thrombin time(P>0.05).The occurrence of supplementary injection was significantly correlated with D-dimer,fibrinogen,thrombin time,and first-time injection dose(P<0.05),and the incidence of supplementary injection was higher in patients who received first-time injection in January,August,September,and December.Both groups achieved successful treatment 6 months after surgery,and there was no significant difference in the incidence of compli-cations.Conclusion Patients with lower limb varicose veins of C3/C4 are more likely to require supplementary injection compared to patients with other levels.The level of D-dimer and fibrinogen at 1 d after surgery is positively correlated with the occurrence of supplementary injection,while the dose of the first injection is negatively corre-lated with the occurrence of supplementary injection.

Objective To investigate the distribution characteristics of serum sIgE antibodies against four allergenic protein components of egg white in children with egg allergy,and then clarify the clinical application value of single component-resolved diagnostics of egg allergy.Methods Serum samples from 197 children with egg allergy were collected.The levels of serum sIgE antibodies against four major allergenic protein components of egg white,including ovomucin,ovalbumin,ovotransferrin,and lysozyme,were detected by the light-excited chemiluminescence assay(LiCA),and the distribution characteristics of sIgE antibodies were analyzed.Results The positive rates of serum sIgE antibodies against ovalbumin,ovomucin,ovotransferrin,and lysozyme in 197 chlidren with egg allergy were 77.16%(152/197),70.56%(139/197),35.02%(69/197),and 18.27%(36/197),respectively.The positive rate of serum sIgE antibody against both ovomucin and ovalbumin was 30.45%.There was a weak correlation between the levels of sIgE antibodies against egg and the cumulative levels of sIgE antibodies against four allergenic protein components(r=0.266 8,P＜0.05).There were signifi-cant individual differences in the levels of serum sIgE antibodies against four allergenic protein components of egg white in the children with egg allergy.Conclusion There is individual heterogeneity in the levels of serum sIgE antibodies against four components of egg white in the children with egg allergy.The detection of sIgE antibodies against egg white components can distinguish different forms of egg allergies,which is of great value for the accurate diagnosis and precise desensitization of children's egg allergy.

To perform a comprehensive analysis of the pathogenic causes of a food poisoning case in a district of Wuhan Cit-y,we investigated the molecular epidemiological relationships among pathogenic bacteria,to aid in traceability analysis of food-borne disease outbreaks,as well as clinical diagnosis and treatment.The pathogenic bacteria in this food poisoning case were i-solated and identified according to GB789.4-2016.The isolated strains were subjected to genotyping with pulsed field gel elec-trophoresis(PFGE).Drug resistance gene analysis,multi-locus sequence typing(MLST),and genome-wide single-nucleotide polymorphism analysis(wgSNP)were conducted via whole genome sequencing(WGS).The evolutionary tree for cluster analy-sis was constructed in fasttree software.Drug susceptibility testing was conducted with the broth microdilution method.A total of 12 strains of Salmonella were detected in seven anal swab samples and two fecal samples from the case,as well as three anal swab samples from unaffected individuals.The serotype of the strains was Salmonella typhimurium.The strain exhibited severe multiple drug resistance,including resistance to amikacin,ampi-cillin,cefazolin,gentamicin,piperacillin,and tetracycline,but susceptibility to other antibiotics.The coincidence rate between drug resistance genes and drug resistance phenotypes was high.PFGE revealed that nine strains from this food poisoning case were highly homologous.WGS revealed that the MLST type was ST19,and varying numbers of SNPs(1-6)were present a-mong strains.The phylogenetic tree revealed nine isolated strains forming a distinct cluster,differing from other Salmonella strains in the database and belonging to a novel clonal branch.The single nucleotide site in the strains was highly homologous to that of GCF in Jiangxi_020221795.1.The food poisoning case was caused by Salmonella typhimurium ST19,and all nine iso-lated strains originated from the same source.The chef is closely connected to this food poisoning case.This strain of Salmo-nella typhimurium belongs to a new clonal branch and exhibits multiple drug resistance.

Objective:To compare the changes in pelvic floor electrophysiology and imaging in female patients with myofascial pelvic pain (MFPP), and to explore the characteristics and significance of these changes.Methods:A total of 49 MFPP patients who were admitted to the of Dalian Women′s and Children′s Medical Center (Group) from January 2019 to October 2021 were randomly selected as the research group, and 41 healthy women during the same period were selected as the control group. Both groups filled in the center′s medical history and general condition survey form. French PHENIX series pelvic floor muscle potential detection instrument was used to detect the resting vaginal muscle potential and maximum muscle potential of the two groups. The static tension, dynamic tension and pelvic floor muscle contraction force of the two groups were measured by French PHENIX series electronic tensioning apparatus with 5° and 10° opening respectively. Two dimensional transperineal ultrasound and three dimensional transvaginal ultrasound produced by B-K Company in Denmark were used to measure the length between the lower margin of the bladder neck from the symphysis pubis and the bladder neck and the bladder bottom (BND, BSD), the diameter of the genital tract hiatus and the angle of the anus and rectum. The area, anterior-posterior diameter, transverse diameter and different damage degrees of levator ani levator were measured.Results:The resting muscle potential of the study group was higher than that of the control group: 2 μV vs. 1 μV ( P<0.05); the maximum vaginal myopotential was higher than that of the control group: 7 μV vs. 6 μV ( P<0.05). The static tension, dynamic tension and contractile force: 204 g/m 2 vs. 175 g/m 2, 450 g/m 2 vs. 410 g/m 2 and 237 g/m 2 vs. 51 g/m 2 of pelvic floor muscle in the study group were higher than those in the control group when the tensioner was opened for 5° ( P<0.05). In resting state, BND, BSD and reproductive tract hiatus diameter in the study group were smaller than those in the control group: 14.0 mm vs. 16.7 mm, 15.3 mm vs. 19.7 mm, 46.7 mm vs. 49.5 mm ( P<0.05). The anal angle was greater than that of the control group: 129° vs. 112° ( P<0.05). The anal right angle in the study group was greater than that in the control group: 113° vs. 109° ( P<0.05). In the resting state, the area of levator ANI hiatus: 10.1 cm 2 vs. 11.6 cm 2, anterior and posterior diameters: 44.2 mm vs. 47.4 mm, transverse diameters and the defect scores of levator ani in the study group were all smaller than those in the control group ( P<0.05). Conclusions:MFPP presents with persistent pelvic floor muscle spasm and loss of coordination. MFPP can be treated by spasmolysis of pelvic floor muscle and fascia, which provides reference value for clinical treatment.

Home enteral nutrition(HEN)has demonstrated advantages in improving patients'quality of life and reducing medical costs.It is widely embraced in the United States,Europe,and other regions.Due to individual differences in the characteristics of HEN preparations,drug interactions,and variations in patient nutritional status,patients need pharmaceutical supervision from a nutritional support pharmacist(NSP)when using HEN.HEN in China is still in its infancy.There are no corresponding norms and guidelines for NSP participation in HEN and a need for specific operating standards.This article delves into the current situation of NSP participation in HEN management,the content of pharmaceutical care,and the value of pharmaceutical services.It aims to offer valuable reference evidence for future practice and research.

Objective To observe the changes of expression of lysyl oxidase family(LOXs)on the retina in acute ocular hypertension(AOH)rats.Methods The SD adult male rats were randomly divided into the control group(CON group)and the AOH group.The rats in the CON group were fed normally without any treatment,and the rats in the AOH group were established AOH model by anterior chamber perfusion.All rats were sacrificed after 2 weeks and retinal tissues were collected.The expression of LOXs[including lysyl oxidase(LOX)and lysyl oxidase-like proteins of LOXL1,LOXL2,LOXL3,LOXL4],and the expression of extracellular matrix(ECM)proteins of Collagen 1/3/4 a1(Col1/3/4 a1),Elastin(Eln),and Fibulin1/4(Fbn 1/4)in the retinal tissues were detected by qRT-PCR.The localiza-tion of LOXs in rat retina was detected by immunohistochemistry.The expression of LOX in retina was detected by Western blot.Results LOXs were expressed to varying degrees in all layers of the rat retina,LOX was mainly expressed in the retinal ganglion cell layer,nerve fiber layer,inner plexiform layer and outer plexiform layer;LOXL1 was mainly expressed in the inner plexiform layer,outer plexiform layer and vascular wall;LOXL2 was mainly expressed in retinal ganglion cell layer,inner plexiform layer and inner nuclear layer;LOXL4 was mainly expressed in the inner plexiform layer and inner nuclear layer;while LOXL3 was only expressed in the vascular wall.Compared with the CON group,the expression of LOX,Col1a1 and Eln in the retina of rats in the AOH group were significantly increased(P<0.05),and there was no significantly significant difference in the expression of LOXL1,LOXL2,LOXL3,LOXL4,Col3a1,Col4a1,Fbn1,Fbn4 mRNAs in the retina of rats between the two groups(P>0.05).Conclusion LOX is highly expressed in the retina of AOH rats,which may be involved in the pathological process of retinal injury caused by high intraocular pressure through ECM remodeling.

Although indigenous malaria has been eliminated in Wuhan since 2013,imported malaria remains a potential threat as an infectious source of local malaria transmission.The epidemiological and clinical characteristics of imported malaria are particularly important in areas where local malaria has been eliminated.This study was aimed at analyzing the epidemiological and clinical characteristics of imported malaria in Wuhan from 2012 to 2019,to provide a basis for further improving the preven-tion and control of imported malaria.Patients in Wuhan diagnosed with imported malaria from January 1,2012,to December 31,2019,were included in this study.A case-control study was con-ducted to analyze the features of patients with severe malaria.Uni-variate and multivariate logistic regression was used to identify risk factors for prolonged hospital length of stay(LOS).Among 229 imported malaria cases,212(92.6％)were in Chinese citizens,and most cases were in men(96.5％).The gender ratio is 28:1,and the age of cases is mainly concertrated between 18 and 50 years old(89.1％).More than 80％of patients were mi-grant workers,and most cases were infections from African countries(92.6％).Plasmodium falciparum(80.8％)was the dominant species.Fifty-three severe malaria cases were identified during the study period.Compared with uncomplicated cases,severe cases tended to occur in patients with no history of malaria(P=0.008),patients infected with Plasmodium falciparum(P=0.009),and patients who were initially misdiagnosed(P＜0.001).The median LOS was 6 days,and the species of infec-tion(Plasmodium falciparum),the use of antimalarial drugs(group B),antipyretic time(longer than 3 days),and the turn-around time of blood smear microscopy(longer than 3 days)were significantly associated with longer LOS(all P＜0.05).Al-though malaria has been eradicated in Wuhan for many years,imported cases continue to pose a threat.Efforts should be made to strengthen malaria knowledge education for outbound personnel.Additionally,medical institutions must enhance diagnosis and treatment capabilities for malaria,and adhere to standardized treatment processes,and the development of drug resistance and occurrence of severe malaria must be prevented.
