Objective: To investigate condom use and associated factors among HIV/AIDS patients receiving antiretroviral therapy (ART) in Fuyang District, Hangzhou City, so as to provide insights into instructing the correct use of condoms and controlling the spread of HIV/AIDS patients. Methods: A face-to-face questionnaire survey was conducted to collect demographic information, sexual behaviors during recent 6 months and condom use of HIV/AIDS patients receiving ART in Fuyang District from May to December, 2022. Descriptive analysis was employed on the proportion of participants who insisted on using condoms at each sexual contact, and a multivariable logistic regression model was used to identify factors affecting condom use at each sexual contact. Results: Totally 111 HIV/AIDS patients who received ART and had sexual contacts during recent 6 months were investigated, with a median age of 43.00 (interquartile range, 19.00) years. There were 82 males (73.87%), 63 married cases (56.76%), 52 cases with homosexual behaviors (46.85%), 110 cases insisting on using condom after ART (99.10%), 101 cases insisting on using condoms at each sexual contact (90.99%). Among 93 patients being aware of HIV infection status of all sexual partners, 93.55% of the patients insisted on using condoms at each sexual contact. Among 105 patients without sexually transmitted diseases (STD) diagnosis and treatment, 94.29% of the patients insisted on using condoms at each sexual contact. Multivariable logistic regression analysis identified aware of HIV infection status of sexual partners (OR=0.046, 95%CI: 0.004-0.560), no STD diagnosis and treatment (OR=0.060, 95%CI: 0.004-0.890) as promoting factors for condom use at each sexual contact among HIV/AIDS patients receiving ART. Conclusions There is a high proportion of condom use at each sexual contact among HIV/AIDS patients receiving ART in Fuyang District. Patients who are aware of sexual partners' HIV infection and have not received STD diagnosis and treatment are more likely to insist on using condoms at each sexual contact.

In September 2020, three pulmonary tuberculosis cases were identified during school physical examinations at a senior high school in a district (School B) of Hangzhou City. Immediate epidemiological surveys were performed by local district and Hangzhou Center for Disease Control and Prevention, and a pulmonary tuberculosis outbreak involving 9 cases in 6 schools were identified. All cases were once Grade 9 students in Class of 2019 at a junior high school (School A), and the source of infection might be a laboratory-confirmed cases (index case) in this class reported in April, 2019. Following exposure to index case, other cases developed disease onset or were screened after entering senior high schools. In November, 2020, tuberculin skin test and chest X-ray scan were performed to screen pulmonary tuberculosis among 43 students and teachers in a class of Grade 9 in Class of 2019 at School A, and 17 students strongly positive for tuberculin skin test were given prophylactic therapy. No pulmonary tuberculosis case were identified until June 2021. It is suggested that early epidemiological surveys facilitates the identification of the epidemiological correlation between cases. Active search for individuals with common exposure history and prophylactic therapy are required if a possible outbreak is found, which is helpful to avoid the spread of the outbreak.

Podocyte infolding glomerulopathy (PIG) is a pathologic type of podocyte glomerulopathy reported recently. The characteristic is that the ultrastructure related to podocytes, such as microspheres and microtubules, are folded into the glomerular basement membrane (GBM) under electron microscope. At present, there are few reports about this disease at home and abroad, and most of them are concentrated in Japan. The clinical characteristics and pathogenesis of PIG are still unclear. In this paper, we report a case of clinical manifestations of nephrotic syndrome, renal biopsy indicated PIG, after the treatment of glucocorticoid, hydroxychloroquine and tacrolimus, the patient's clinical symptoms were relieved and urinary protein decreased.

Objective Explore changes in polysaccharides in Jiangxiangru before and after ginger juice preparation,and evaluate polysaccharide anti-inflammatory and antioxidant activities before and after processing.Methods The contents of Jiangxiangru polysaccharide(JXRPs)and Ginger juice processed of Jiangxiangru polysaccharide(JZJXRPs)before and after processing were determined by phenol-sulfuric acid method.We used the swelling model in rats and endotoxin(LPS)to establish the RAW264.7 mouse macrophage inflammation model.The optimal administration concentration was determined using a cell proliferation(MTT)assay.Enzyme-linked immunosorbent assay(ELISA)were used to measure Interleukin-6(IL-6),Interleukin-12(IL-12),Nitric oxide(NO),Interleukin-4(IL-4),and Interleukin-10(IL-10).Bleeding time of mice by tail cutting was observed to evaluate the hemostatic effect.The ability to remove 1,1-diphenyl-2-picryl-hydrazyl radical(DPPH)and 2,2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate)(ABTS)was used to evaluate in vitro antioxidant activity.Results The contents of JXRPs and JZJXRPs were 13％and 22％,respectively.In swollen rats at 4 h after injection,compared with the model group,200 mg/kg JXRPs and 100 mg/kg JZJXRPs significantly reduced rat swelling(P＜0.05).In vitro anti-inflammation assessment showed that the polysaccharides before and after processing significantly inhibited secretion of IL-6,IL-12,and NO(P＜0.01)and promoted secretion of IL-4 and IL-10(P＜0.01),and also that processing post-effects were stronger.The hemostatic experiment show that,compared with the control group,JXRPs increased hemostasis,but without a significant difference,and no significant difference was found using JZJXRPs,although high doses showed a trend to increase hemostasis.In vitro antioxidant activity showed that JXRPs and JZJXRPs had different scavenging abilities for DPPH and ABTS with IC50 values of JXRPs of 0.2215 and 0.2110 mg/ml,respectively,and IC50 values of JZJXRPs of 0.1651 and 0.1884 mg/mL,respectively.Conclusions After Jiangxiangru is produced in ginger juice,it promotes dissolution of polysaccharides and increases polysaccharide content.Anti-inflammatory,hemostasis,and antioxidant capacities are stronger in JZJXRPS than JXRPS,which lays the foundation for follow-up research and clinical applications of JXRPS.

Objective:To develop the Suicide Outcomes Scale for Undergraduates with Suicidal Ideation(SO-SUSI)and test its validity and reliability.Methods:Based on semi-structured interview,literature review and expert discussion,main aspects and indicator system were defined.The initial version of SOSUSI was formed,and items were either modified from existing scales targeting the relevant constructs,or compiled according to previous inter-view results.A total of 607 undergraduates with suicidal ideation were enrolled.The sample was randomly divided in half,one half(n=317)was used for item analysis and exploratory factor analysis,and another half(n=290)for confirmatory factor analysis.All data were used for reliability analysis.The Self-rating Depression Scale(SDS)and Suicidal Intent(SI)were used for criterion validity.Results:The SOSUSI included 39 items in 4 dimensions(nega-tive reinforcement of suicide,negative consequences of suicide,loss of suicide,and positive reinforcement of sui-cide)which explained 50.10％of the total variance.Confirmatory factor analysis showed that the four-factor struc-ture model fitted well(x2/df=3.27,CFI=0.92,TLI=0.91,IFI=0.92,SRMR=0.09).The scores of negative re-inforcement and positive reinforcement of suicide were positively correlated with the SDS and SI scores(ICC=0.15-0.33,Ps＜0.05),while the scores of negative consequences and loss of suicide were negatively correlated with the SI scores(ICC=-0.42--0.56,Ps＜0.05).The Cronbach's α coefficients of each dimension ranged from 0.79 to 0.91.Conclusion:The Suicide Outcomes Scale for Undergraduates with Suicidal Ideation(SOSUSI)has good validity and internal consistency reliability.

Objective To analyze the risk factors of unplanned reoperation and construct a nomogram-based risk prediction model to identify high-risk patients,so as to provide a basis for perioperative manage-ment to reduce the rate of reoperation.Methods A total of 880 patients with underwent unplanned reopera-tion between 2018 and 2021 were included as the unplanned reoperation group.Using propensity score matc-hing,2640 patients were matched in a 1∶3 ratio to form the control group.Potential risk factor indicators were collected and subjected to univariate analysis.Significant indicators were then selected for multivariable logistic regression analysis to construct the risk prediction model.The predictive value of the model was evalu-ated.Results For unplanned reoperation,The number of complications 3-5 (OR=1.84),the number of complications 6-10 (OR=2.94),combined with maligant tumor (OR=1.75),combined with end-stage renal disease (OR=1.92),major surgery grade 3 (OR=4.27),major surgery grade 4 (OR=7.26),and incision grade Ⅰ,Ⅱ,Ⅲ (OR=2.18,1.97,6.85) were independent factors (P<0.05).The model passed the calibra-tion degree test,and the area under ROC curve (AUC) was 0.715,indicating good model differentiation.Con-clusion A risk prediction model based on risk factors can help identify high-risk populations for unplanned reoperation and suggest corresponding measures for prevention.

OBJECTIVE: To explore the genetic basis for fetus with bilateral lateral ventriculomegaly. METHODS: Fetus umbilical cord blood and peripheral blood samples of its parents were collected. The fetus was subjected to chromosomal karyotyping, whilst the fetus and its parents were subjected to array comparative genomic hybridization (aCGH). The candidate copy number variation (CNV) were verified by qPCR, Application goldeneye DNA identification system was used to confirm the parental relationship. RESULTS: The fetus was found to have a normal karyotype. aCGH analysis indicated that it has carried a 1.16 Mb deletion at 17p13.3, which partially overlapped with the critical region of Miller-Dieker syndrome (MDS), in addition with a 1.33 Mb deletion at 17p12 region, which is associated with hereditary stress-susceptible peripheral neuropathy (HNPP). Its mother was also found to harbor the 1.33 Mb deletion at 17p12. qPCR analysis confirmed that the expression levels of genes from the 17p13.3 and 17p12 regions were about the half of that in the normal control, as well as the maternal peripheral blood sample. Parental relationship was confirmed between the fetus and its parents. Following genetic counseling, the parents has chosen to continue with the pregnancy. CONCLUSION The fetus was diagnosed with Miller-Dieker syndrome due to the de novo deletion at 17p13.3. Ventriculomegaly may be an important indicator for prenatal ultrasonography in fetuses with MDS.

OBJECTIVE: To explore the genetic etiology of two patients with developmental delay and intellectual disability. METHODS: Two children who were respectively admitted to Henan Provincial People's Hospital on August 29, 2021 and August 5, 2019 were selected as the study subjects. Clinical data were collected, and array comparative genomic hybridization (aCGH) was carried out on the children and their parents for the detection of chromosomal microduplication/microdeletions. RESULTS: Patient 1 was a 2-year-and-10-month female and patient 2 was a 3-year-old female. Both children had featured developmental delay, intellectual disability, and abnormal findings on cranial MRI. aCGH revealed that patient 1 has harbored arr[hg19] 6q14.2q15(84621837_90815662)×1, a 6.19 Mb deletion at 6q14.2q15, which encompassed ZNF292, the pathogenic gene for Autosomal dominant intellectual developmental disorder 64. Patient 2 has harbored arr[hg19] 22q13.31q13.33(46294326_51178264)×1, a 4.88 Mb deletion at 22q13.31q13.33 encompassing the SHANK3 gene, haploinsufficiency of which can lead to Phelan-McDermid syndrome. Both deletions were classified as pathogenic CNVs based on the guidelines of American College of Medical Genetics and Genomics (ACMG) and were not found in their parents. CONCLUSION The 6q14.2q15 deletion and 22q13-31q13.33 deletion probably underlay the developmental delay and intellectual disability in the two children, respectively. Haploinsufficiency of the ZNF292 gene may account for the key clinical features of the 6q14.2q15 deletion.

Objective:To investigate the characteristics of neointimal hyperplasia (NIH) in patients with in-stent restenosis (ISR) over 5 years post-drug-eluting stent (DES) implantation based on optical coherence tomography (OCT).Methods:In this cross-sectional study, patients with DES-ISR who underwent OCT examination at PLA General Hospital between March 2010 and March 2022 were retrospectively included. All patients were divided into≤5 years DES-ISR group and>5 years DES-ISR group according to the time interval after DES implantation. Quantitative and qualitative analyses were conducted on OCT images to compare the clinical data and lesion characteristics of two patient groups. Furthermore, the independent clinical predictive factors of in-stent neoatherosclerosis (ISNA) were analyzed by multivariable logistic regression.Results:A total of 230 DES-ISR patients with 249 lesions were included, with an age of (63.1±10.4) years and 188 males (81.7%). The median interval after DES implantation was 6 (2, 9) years. There were 117 patients (122 ISR lesions) in the≤5 years DES-ISR group, and 113 patients (127 ISR lesions) in the>5 years DES-ISR group. Compared with≤5 years DES-ISR,>5 years DES-ISR showed more heterogeneous patterns (65.4% (83/127) vs. 48.4% (59/122), P=0.007), diffuse patterns (46.5% (59/127) vs. 31.2% (38/122), P=0.013), macrophage accumulations (44.1% (56/127) vs. 31.2% (38/122), P=0.035) in NIH and higher prevalence of ISNA (83.5% (106/127) vs. 72.1% (88/122), P=0.031). According to multivariable logistic regression, the independent predictive factor for ISNA was female ( OR=0.44, 95% CI 0.21-0.90, P=0.026). Female ( OR=0.48, 95% CI 0.23-0.99, P=0.046) and low-density lipoprotein cholesterol level ( OR=1.62, 95% CI 1.01-2.59, P=0.046) were independent predictive factors, respectively, for lipid ISNA. Calcified ISNA was independently associated with time interval of post-DES implantation ( OR=1.18, 95% CI 1.07-1.29, P=0.001). Conclusion:DES-ISR patients with a time interval of>5 years after stent implantation have a higher prevalence of ISNA and more complex lesions. Gender, the level of low-density lipoprotein cholesterol, and the time interval post-DES implantation are independently correlated with ISNA, lipid ISNA, and calcified ISNA.

Objective To explore the application value of 1 024×1 024 reconstruction matrix combined with iterative reconstruc-tion algorithm(Karl)in deep inferior epigastric artery(DIEA)computed tomography angiography(CTA).Methods A total of 40 patients who underwent DIEA CTA were prospectively selected and the original data were reconstructed by grouping.Group A was reconstructed using a conventional 512×512 matrix combined with Karl 5 grade.Group B was reconstructed using 1 024×1 024 recon-struction matrix combined with Karl 5,7,and 9 grades,respectively,and 3 subgroups B1-B3 were obtained.The CT and standard devia-tion(SD)values of the external iliac artery and psoas major muscle were measured on axial images,and signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated.A 3-point scale was used to evaluate the perforating vessels from the DIEA,intramuscular course,point of emergence,superficial inferior epigastric artery(SIEA)and superficial inferior epigastric vein(SIEV)on volume ren-dering(VR)and maximum intensity projection(MIP)images by two observers,and a 5-point scale was used to evaluate the overall image quality on axial images.Results With the increase of Karl grade in groups B1 to B3,the SD value of the external iliac artery decreased gradually(P＜0.05),while SNR and CNR increased gradually(P＜0.05).The SD values of the external iliac artery in group B2 and group B3 were lower than those in group A(P＜0.05),and SNR and CNR were higher than those in group A(P＜0.05).There was a good consistency in the subjective evaluation between the two observers(Kappa values=0.773-0.872,P＜0.05).The perforating vessels from the DIEA,intramuscular course,point of emergence,SIEA and SIEV display and overall image quality subjective scores of group B2 and group B3 were better than those of group A(P＜0.05),and the scores of group B2 showed the greatest improvement.Conclusion The 1 024 × 1 024 reconstruction matrix combined with the Karl 7 reconstruction algorithm can optimize the image quality and improve the display of the DIEA and perforator microvessels.
