The means of survival of genomic dsRNA of reoviruses from dsRNA-triggered and Dicer-initiated RNAi pathway remains to be defined.The present study aimed to investigate the effect of Grass carp reovirus (GCRV) replication on the RNAi pathway of grass carp kidney cells (CIK).The dsRNA-triggered RNAi pathway was demonstrated unimpaired in CIK cells through RNAi assay.GCRV-specific siRNA was generated in CIK cells transfected with purified GCRV genomic dsRNA in Northern blot analysis; while in GCRV-infected CIK cells,no GCRV-specific siRNA could be detected.Infection and transfection experiments further indicated that replication of GCRV correlated with the increased transcription level of the Dicer gene and functional inhibition of in vitro synthesized egfp-siRNA in silencing the EGFP reporter gene.These data demonstrated that although only the genomic dsRNA of GCRV was sensitive to the cellular RNAi pathway,unidentified RNAi suppressor protein(s) might contribute to the survival of the viral genome and efficient viral replication.

Methods: Literature on influencing factors for medication compliance in patients with comorbidities of chronic diseases were retrived from CNKI, Wanfang Data, VIP, SinoMed, PubMed, Web of Science, Cochrane Library and Embase from inception to January 20, 2024. After independent literature screening, data extraction, and quality assessment by two researchers, a meta-analysis was performed using RevMan 5.4 and Stata 16.0 softwares. Literature were excluded one by one for sensitivity analysis. Publication bias was assessed using Egger's test. Results: Initially, 7 365 relevant articles were retrieved, and 35 of them were finally included, with a total sample size of about 150 000 individuals. There were 30 cross-sectional studies and 5 cohort studies; and 11 high-quality studies and 24 medium-quality studies. The meta-analysis showed that the demographic factors of lower level of education (OR=2.148, 95%CI: 1.711-2.696), lower economic income (OR=1.897, 95%CI: 1.589-2.264), male (OR=0.877, 95%CI: 0.782-0.985), living alone (OR=2.833, 95%CI: 1.756-4.569) and unmarried (OR=2.784, 95%CI: 1.251-6.196); the medication treatment factors of polypharmacy (OR=1.794, 95%CI: 1.190-2.706), potentially inappropriate medication (OR=2.988, 95%CI: 1.527-5.847), low frequency of daily medication (OR=0.533, 95%CI: 0.376-0.754) and adverse drug reactions (OR=3.319, 95%CI: 1.967-5.602); the disease factors of long course of disease (OR=2.118, 95%CI: 1.643-2.730), more comorbidities (OR=1.667, 95%CI: 1.143-2.431) and cognitive impairment (OR=2.007, 95%CI: 1.401-2.874); and the psychosocial factors of poor belief in taking medication (OR=1.251, 95%CI: 1.011-1.547), poor self-rated health (OR=1.990, 95%CI: 1.571-2.522) and being guided by healthcare professionals (OR=0.151, 95%CI: 0.062-0.368) were the influencing factors for medication compliance in patients with chronic comorbidities. Conclusion The medication compliance in patients with comorbidities of chronic diseases is associated with demographic factors, pharmacological factors, disease factors and psychosocial factors, mainly including living alone, adverse drug reactions, course of disease, number of comorbidities and medication beliefs.

Objective: To investigate the current status of HIV-related stigma among college students in Guilin,and to explore the impact of perspective-taking and empathy on HIV-related stigma among college students. Methods: The stratified cluster sampling method was used to select college students from 4 universities in Guilin city. Stratified randomization was used to assign all subjects into a control group (410) and an experimental group (396) for randomized controlled trials,and the HIV-related Stigma Questionnaire and the Basic Empathy Scale were used before and after the intervention. Results: Before the intervention of perspective-taking,there were no statistically significant differences between two groups in subscale scores and total scores of HIV-related stigma (t=0.80，0.35，-0.62，-0.10，P>0.05); However, signiticant differences in subscale scores and total score in HIV-related stigma were found after intervention (t=3.53，2.21，2.30，3.98，P<0.05). There was no statistically singnificant in the scores of all dimensions of empathy level and the total score before the intervention (t=0.10,-0.27,-0.08,P>0.05), dimensional score and total score in empathy were statistically significant after intervention (t=-2.15，-3.06，P<0.05). Empathy played an intermediary role of 14.08% between opinion selection and HIV stigma. Conclusion HIV-related stigma exists among college students in Guilin,and perspective-taking intervention effectively reduces its AIDS stigma. Empathy plays an intermediary role between them.

The treatment of bone defects caused by fractures or bone tissue lesions has always been a difficult problem in the field of orthopedics.Implantation of high-performance titanium alloy prosthesis is an effective method to treat bone defects.3D printing technology can produce low-modulus titanium alloy implants with porous structures,providing a better solution to the above problems.This technology is convenient to design and has a huge advantage in making orthopedic implants.The article used electron beam melting in 3D printing technology to create two samples of Ti-6Al-4V prosthesis,including solid structural pelvic prosthesis and porous structural pelvic prosthesis.The mechanical properties of the prosthesis showed that the yield and tensile strengths of the rod tensile specimen were 894 MPa and 956 MPa,respectively,and the compressive modulus and compressive strength of the porous pelvic prosthesis were 55 GPa and 65.2 MPa,respectively.The results of the L929 cytotoxicity assay and the MC3T3-E1 cell adhesion assay demonstrated good biocompatibility of the prosthetic samples.New Zealand white rabbits were used to prepare the femoral joint cavity defect models and two pelvic prostheses were implanted.A microscopic CT scan 4 weeks after implantation showed that the bone defect caused by the drill had healed and that the porous structure of the pelvic prosthesis formed a new trabecular structure within the hole.In conclusion,the 3D printed Ti-6Al-4V pelvic prosthesis has excellent mechanical properties,biocompatibility,and the ability to promote new bone growth.

Chemokines and their receptors play crucial roles in nervous system diseases,among which the CXC chemokine receptor 3(CXCR3)is an important mediator of intercellular communication.CXCR3 not only participates in inflammatory chemotaxis and malignant behaviors of tumor cells but also regulates the neurologic diseases.CXCR3 and its ligands directly or indirectly contribute to neuroinflammation and neuroimmunity,and potentially serve as therapeutic targets for diseases like multiple sclerosis,Alzheimer's disease,and glioma and so on.This review discusses the expression and impact of CXCR3 and its ligands in neurological diseases such as multiple sclerosis,neurologic tumors,neurodegenerative diseases,and neuropathic pain,as well as their associations with CXCR3 ligands.Understanding the mechanisms linking CXCR3 to these diseases could facilitate its potential as an early diagnostic biomarker and a target for drug intervention,and provide the basis of studying the occurrence and developmant of nervous system disease.

The search period was from establishing the database to August 30, 2023.Results:A total of 16 articles were included, including three guidelines, four expert consensus, seven systematic reviews, and two meta-analyses. Twenty-seven pieces of evidence were summarized from six aspects of compliance assessment, educational intervention, behavioral intervention, optimized treatment program, technical reminder intervention, and social-psychological-emotional intervention.Conclusions:The best evidence of medication adherence interventions for patients with multiple chronic conditions summarized provides a reference for medical and nursing staff to develop medication adherence interventions.

Objective:To investigate the application value of Th1/Th2 cytokines,interleukin-17(IL-17)and serum tumor markers in the diagnosis,prognosis and recurrence of breast cancer.Methods:A total of 200 patients with breast cancer admitted to Inner Mongolia Hospital of Peking University Cancer Hospital from December 2021 to December 2022 were selected,and they were divided into negative group(60 cases),weakly positive(80 cases)group and positive group(60 cases)according to immunohistochemistry indicators.In addition,another 60 persons who underwent physical examination were selected as healthy control group.The changes of the Th1/Th2,IL-17,CA125,CYFRA21-1,CA153 and CEA levels were observed,and the clinical value of the combined detection of the 6 indicators in predicting the prognosis and recurrence of breast cancer was investigated.Results:The results of comparative analysis indicated that the clinical pathological features related to recurrence,histological grading,tumor diameter and lymph node metastasis(x2=7.552,12.037,12.063,8.543,P＜0.05),respectively.Multivariate analysis showed that tumor recurrence,tissue grading,tumor diameter and lymph node metastasis were the important factors for the prognosis of patients with breast cancer(OR=3.096,3.050,3.425,3.031,P＜0.05).Compared with the single prediction of Th1/Th2,IL-17,CA125,CYFRA21-1,CA153 and CEA,the combined prediction of 6 indicators had higher clinical value for prognosis and recurrence of patients with breast cancer,which sensitivity,accuracy and specificity were respectively 96%,93.46%and 85%.Conclusion:The observation on the changes of the combined predictive levels of 6 items,which include Th1/Th2,IL-17,CA125,CYFRA21-1,CA153 and CEA of patients,indicates that the combined detection has high sensitivity and accuracy.This highly efficient and convenient detection method can provide references for improving the prognosis,reducing the recurrence and enhancing the accuracy of assessment.

Objective:To report a case of Kufor-Rakeb syndrome caused by novel ATP13A2 mutation, collect the cases related to ATP13A2 gene mutation published in recent years, summarize the clinical manifestations of the disease, and broaden the clinical diagnostic thinking. Methods:The clinical manifestations of a newly diagnosed patient with Kufor-Rakeb syndrome caused by ATP13A2 gene mutation admitted to Zhongda Hospital, Southeast University on November 26, 2021, were summarized. The related cases of ATP13A2 mutation published from January 2000 to December 2021 were searched through the PubMed and CNKI databases using the keywords "ATP13A2" and "Parkinson′s disease". The onset age, clinical symptoms, family history, genetic testing, and levodopa responsiveness results of the patients were collected. Results:The patient is a 52-year-old female with the main clinical symptoms of static tremor and bradykinesia. Physical examination showed a gear like increase in muscle tension in the right upper limb, involuntary shaking of the right hand and slow movement. She had good responsiveness to levodopa, and the magnetic resonance imaging and susceptibility weighted imaging of the head showed a lack of clear observation of bilateral black matter swallowtail sign. Whole exome sequencing showed that mutations c.3010A>G (p.S1004G) and c.1195+5G>A (splice) were found in the ATP13A2 gene, both of which were not reported. The c.3010A>G (p.S1004G) mutation originated from the mother, and the c.1195+5G>A (splice) mutation originated from the father. In the retrospective literature review, a total of 10 cases were collected, with onset ages ranging from 18 months to 24 years. Among them, 4/10 patients′ parents married close relatives, and the clinical manifestations were mainly motor symptoms of Parkinson′s disease. In addition, 5/10 patients had cognitive dysfunction, and 3/10 patients had mental symptoms. And demonstrations of most patients′ magnetic resonance imaging were normal in the early stage of the disease, and as the disease progressed, some patients′ imaging results showed specific changes, such as whole brain atrophy and changes in the corpus callosum. Meanwhile, 8/10 patients showed good responsiveness to levodopa. Conclusions:Kufor-Rakeb syndrome is a special type of adolescent levodopa responsive Parkinson′s disease caused by ATP13A2 mutation, which is an autosomal recessive disorder. In addition to motor symptoms such as static tremor and bradykinesia, its clinical manifestations may also be accompanied by non motor symptoms such as cognitive and psychiatric disorders. The disease responds well to treatment with levodopa.

Objective:To compare the perioperative complications and prognosis of intracorporeal and extracorporea lileal conduit urinary diversion(ICUD or ECUD)following robot-assisted radical cystectomy(RARC).Methods:The data of 95 patients who underwent RARC treatment in Nanjing Drum Tower Hospital from March 2016 to June 2019 were retrospectively analyzed. Among them, 37 underwent ICUD and 58 underwent ECUD. In the ICUD group, there were 32 males and 5 females, aged(68.0±7.8) years, body mass index (BMI) of (24.1±3.4) kg/m 2, American Society of Anesthesiologists(ASA)score of 1-2 in 4 cases(10.8%), ASA score of 3-5 in 33 cases(89.2%), preoperative hemoglobin of(126.5±14.2)g/L, albumin of(39.0±2.2)g/L, and C-reactive protein of 4.0(2.0-8.5) mg/L. In the ECUD group, there were 53 males and 5 females, aged(67.5±9.0)years, BMI of(24.2±3.6)kg/m 2, ASA score of 1-2 in 16 cases(27.6%), ASA score of 3-5 in 42 cases (72.4%) , preoperative hemoglobin of(129.0±12.4)g/L, albumin (38.2±3.1) g/L, and C-reactive protein of 4.9 (3.1-14.4) mg/L. There was no significant difference in preoperative data between the two groups ( P>0.05). The two groups underwent RARC and pelvic lymph node dissection similarly. The ICUD group underwent a total intracorporeal ileal conduit and the ECUD group underwent extracorporeal ileal conduit with direct vision through a median incision in the lower abdomen.There were 32 cases (86.5%) and 46 cases (79.3%) undergoing expanded pelvic lymph node dissection in the ICUD group and the ECUD group respectively, and the difference was not statistically significant ( P=0.374). The complications were graded according to the Clavien-Dindo grading system. The perioperative complications and prognosis of the two groups were compared. Results:The operation time of the ICUD group and the ECUD group were (430±63) min vs. (410±69) min, respectively ( P=0.163). The estimated blood loss were (435±233) ml vs. (388±277) ml, respectively ( P=0.182). Intraoperative blood transfusion were 10 cases (27.0%) and 12 cases (20.7%)( P=0.475). None of the above differences were statistically significant. Postoperative albumin of the ICUD group and the ECUD group were (31.5±2.4) g/L vs. (31.0±2.8) g/L ( P=0.387), postoperative C-reactive protein were 30.9 (10.4-52.1) mg/L vs.29.5 (14.4-58.5) mg/L ( P=0.655) and postoperative hemoglobin were (110.0±13.8) g/L vs. (113.7±13.4) g/L ( P=0.187). The postoperative feeding recovery were 4(3-5) d vs. 4(3-5) d ( P=0.752) and the postoperative hospital stay were 13(10-19) d vs. 13(11-18) d ( P=1.000). There was no statistically significant difference in perioperative data. The postoperative pathological examination results of ICUD group and ECUD group showed that there were 17 cases (45.9%) vs.19 cases (32.8%) in T a/T 1/Tis stage, 12 cases (32.4%) vs. 18 cases (31.0%) in T 2 stage, 5 cases (13.5%) vs. 19 cases (32.8%) in T 3 stage, 3 cases (8.1%) vs. 2 cases (3.4%) in T 4 stage, respectively and the difference was not statistically significant( P=0.166). The number of lymph nodes removed were (18.2±6.7) vs.(16.5±7.9)( P=0.178) and the number of patients with positive lymph nodes were 6(16.2%) vs.11(19.0%), respectively( P=0.733). None of the patients had positive margins. There was no statistically significant difference in pathological examination overall. There were 14 cases (37.8%) in the ICUD group and 21 cases (36.2%) in the ECUD group experiencing complications within 30 days after operation and the difference was not statistically significant( P=0.872). The complications within 90 days after operation were 14 cases (37.8%) vs. 24 cases (41.4%) respectively and the difference was not statistically significant( P=0.731). Clavien-Dindo grade Ⅲ-Ⅴ complications in the two groups were 1 case (2.7%) vs.1 case (1.7%) respectively, with no significant difference ( P=0.849). One patient in the ICUD group developed an intestinal anastomotic leakage and underwent reoperation for repairing and 1 patient in the ECUD group developed mechanical intestinal obstruction and underwent reoperation. The rate of readmission within 90 days after operation of the ICUD group was lower than that of the ECUD group, but the difference was not statistically significant [3 cases (8.1%) vs. 11 cases (19.0%), P=0.090]. Postoperative follow-up was 13-53 months and the median follow-up of ICUD group and ECUD group were 19 months and 31 months respectively. There was no significant difference in the survival curve between the two groups( P=0.746). The 1-year survival rate was 91.9% in the ICUD group and 91.4% in the ECUD group. Routine re-examination of urinary system CT or B-ultrasound was performed 3 months, 6 months and 1 year after surgery. The incidence of ureteral dilatation/hydronephrosis in the ICUD group was lower than that of the ECUD group, with 4.1%(3 sides) vs. 14.7%(17 sides)( P=0.020). Conclusion:Compared with RARC+ ECUD, RARC+ ICUD does not increase the incidence of complications within 90 days after surgery and may reduce the risk of upper urinary tract dilatation.
