The ocular fundus vasculature, serving as a critical window for monitoring disease progression, represents one of the primary targets of hypoxic injury. A growing body of evidence suggests associations between specific ocular vascular pathologies and sleep-disordered breathing. Obstructive sleep apnea(OSA)has been implicated in fundus lesions through its detrimental effects on the central retinal artery, retinal veins, retinal microvasculature, and choroidal vessels. Mechanistically, these effects are linked to OSA-induced intermittent hypoxia, which drives hemodynamic disturbances, oxidative stress, inflammatory responses, altered blood composition, endothelial dysfunction, and neuroendocrine/metabolic dysregulation. This review synthesizes current evidence on OSA-related retinal vascular injury and elucidates its mechanistic pathways. The goal is to identify sensitive and specific retinal vascular biomarkers to facilitate the early detection of OSA and its associated complications.

Objective:To compare the safety and efficacy of novel en-bloc Holmium laser enucleation of the prostate(HoLEP)with complete membranous urethral mucosa sparing technique with traditional 2-lobe technique HoLEP in benign prostatic hyperplasia(BPH)treatment.Methods:The data of BPH patients treated with HoLEP from January 2023 to May 2024 in Xinhua Hospital,School of Medicine,Shanghai Jiaotong University were retrospectively reviewed. Seventy-two patients received novel en-bloc HoLEP with complete membranous urethral mucosa sparing technique(novel en-bloc group),while 79 patients received traditional 2-lobe technique HoLEP(traditional 2-lobe technique group).There was no significant difference between novel en-bloc group and traditional 2-lobe technique group in the age[(71.0 ± 7.1)years vs.(69.8 ± 6.5)years],body mass index[(24.5 ± 2.8)kg/m 2 vs.(23.9 ± 3.5)kg/m 2],international prostate symptom score(IPSS)[26.0(22.0,28.0)vs. 25.0(22.0,28.0)],quality of life(QOL)score[5.0(5.0,6.0)vs. 5.0(5.0,6.0)],prostate sepcific antigen(PSA)[4.98(2.40,11.11)ng/ml vs. 4.38(1.62,7.54)ng/ml]and prostate volume[(74.06 ± 42.67)ml vs.(70.10 ± 33.94)ml](all P > 0.05). The incidence of acute urinary retention in novel en-bloc group was significantly higher than that in traditional 2-lobe technique group[31.94%(23/72)vs. 17.72%(14/79), P = 0.042].The procedure of novel en-bloc was shown as followed:expose the prostatic capsule near the verumontanum and expand the initial capsule plane on both sides. The prostatic urethral mucosa was cut off in a circular pattern medial to the external urethral sphincter,which could form a complete “circular mucosal pad”. Seperate the apical gland along the capsule plane at 12 o’clock and expand the capsule plane until the bladder neck was reached.The bladder neck was then used as a marker so as to separate the glands on both sides along the capsule plane and merge with the initial plane. The entire lobe of the prostate was finally removed along the surgical capsule of the prostate. The procedure of traditional two lobe method was shown as followed:expose the prostatic capsule near the verumontanum and then divide the prostate into two lobes by longitudinal incision at 6 and 12 o’clock. The mucosa was horizontally cut at 12 o’clock,medial to the external urethral sphincter in order to preserve the apical urethral mucosal flap. The twp lobes were then removedd respectively along the capsule layer. The surgery-related indicators,perioperative complications and other data were compared between the two groups,as well as IPSS,QOL score,lower urinary tract symptoms,and the incidence of stress urinary incontinence in the two groups 1 month after surgery. Results:Compared with the patients underwent 2-lobe technique HoLEP,the patients underwent novel en-bloc HoLEP had lower hemoglobin loss[0.50(-5.50,7.50)g/L vs. 7.00(1.00,13.25)g/L, P = 0.003],lower operation time[(72.06 ± 34.37)min vs.(85.42 ± 40.35)min, P = 0.030],higher surgical efficacy[(0.72 ± 0.31)g/min vs.(0.55 ± 0.29)g/min, P = 0.002]and lower incidence of stress urinary incontinence one month after operation[2.78%(2/72)vs. 10.13%(8/79), P = 0.070]. There was no significant difference in the incidence of postoperative gross hematuria[0 vs. 2.53%(2/79)],postoperative sepsis[1.39%(1/72)vs. 1.27%(1/79)],postoperative dysuria[4.17%(3/72)vs. 5.06%(4/79)],postoperative IPSS improvement[12.0(11.0,13.0)vs. 12.0(10.0,14.0)]and postoperative QOL improvement[3.0(2.0,3.0)vs. 3.0(2.0,3.0)]between the two groups( P > 0.05). The patients were further divided into 2 sub-groups according to whether prostate volume ≥ 60 ml or not. In the patients of prostate volume < 60 ml,surgical efficacy was significantly higher in novel en-bloc HoLEP group than that in traditional 2-lobe technique group[(0.55 ± 0.25)g/min vs.(0.41 ± 0.19)g/min, P = 0.028]. In the patients of prostate volume ≥ 60 ml,the surgical efficacy of novel en-bloc HoLEP was also higher[(0.88 ± 0.28)g/min vs.(0.66 ± 0.31)g/min, P = 0.006]. Conclusions:Novel en-bloc HoLEP with complete membranous urethral mucosa sparing technique was demonstrated to has lower blood loss,shorter operation time,higher surgical efficacy and lower incidence of stress urinary incontinence,which is suitable of all sizes of prostate.

BACKGROUND:
Current replacement procedures for stenosis or occluded arteries using prosthetic grafts have serious limitations in clinical applications, particularly, endothelialization of the luminal surface is a long-standing unresolved problem.METHOD: We produced a cell-based hybrid vascular graft using a bioink engulfing adipose-derived mesenchymal stromal cells (ADSCs) and a 3D bioprinting process lining the ADSCs on the luminal surface of GORE-Tex grafts. The hybrid graft was implanted as an interposition conduit to replace a 3-cm-long segment of the infrarenal abdominal aorta in Rhesus monkeys.
RESULTS:
Complete endothelium layer and smooth muscle layer were fully developed within 21 days post-implantation, along with normalized collagen deposition and crosslinking in the regenerated vasculature in all monkeys. The regenerated blood vessels showed normal functionality for the longest observation of more than 1650 days. The same procedure was also conducted in miniature pigs for the interposition replacement of a 10-cm-long right iliac artery and showed the same long-term effective and safe outcome.
CONCLUSION
This cell-based vascular graft is ready to undergo clinical trials for human patients.

Objective: To evaluate the household secondary attack rates of the SARS-CoV-2 Delta variant and the associated factors. Methods: A COVID-19 outbreak caused by the Delta variant occurred in Nanjing in July 2021. A total of 235 cases with current addresses in Nanjing were reported from 171 households. The subjects in this study were selected from household close contact(s) of infected cases. The information on household index cases and their contacts were collected, and the household secondary attack rate (HSAR) and the risk factors were analyzed by the multi-factor logistic regression model. Results: A total of 234 cases of household close contacts and 64 household secondary cases were reported from 103 households, and the HSAR was 27.4% (64/234, 95%CI:22.0% to 33.4%). The proportions of household size for 2 to 3, 4 to 5, and 6 to 9 were 64.1% (66), 26.2% (27) and 9.7% (10), respectively. A total of 35 cases of household cluster outbreaks were reported (35/103, 34.0%). The number of the first case in the household (FCH) was 103 and males accounted for 27.2% (28 cases), with the median age (Q1, Q3) of 49 (9, 56). The number of household close contacts was 234 and males accounted for 59.0% (138 cases), with the median age (Q1, Q3) of 42 (20, 55) and the median exposure period (Q1, Q3) of 3 (1, 3) days. The multi-factor logistic regression model showed that the higher HSAR was observed in the FCH with the features of airport staff (OR=2.913, 95%CI:1.469-5.774), detection from home quarantine screening (OR=6.795, 95%CI:1.761-26.219) and detection from mass screening (OR=4.239, 95%CI:1.098-16.368). Meanwhile, higher HSAR was observed in cases with longer household exposure (OR=1.221, 95%CI:1.040-1.432), non-vaccination (OR=2.963, 95%CI:1.288-6.813) and incomplete vaccinations (OR=2.842, 95%CI:0.925-8.731). Conclusion: The generation interval of the Delta variant is shortened, and the ability of transmission within the household is enhanced. In the outbreak in Nanjing, the associated factors of HSAR are occupation, detection route, vaccination and exposure period.

External apical root resorption is among the most common risks of orthodontic treatment, and it cannot be completely avoided and predicted. Risk factors causing orthodontic root resorption can generally be divided into patient- and treatment-related factors. Root resorption that occurs during orthodontic treatment is usually detected by radiographical examination. Mild or moderate root absorption usually does no obvious harm, but close attention is required. When severe root resorption occurs, it is generally recommended to suspend the treatment for 3 months for the cementum to be restored. To unify the risk factors of orthodontic root resorption and its clinical suggestions, we summarized the theoretical knowledge and clinical experience of more than 20 authoritative experts in orthodontics and related fields in China. After discussion and summarization, this consensus was made to provide reference for orthodontic clinical practice.

Objective: To investigate the influence of individual factors and labor organization on the prevalence of neck pain (hereinafter referred to as neck pain) in automotive assemblers, and to provide a basis for enterprises to optimize neck pain interventions. Methods: A cluster random sampling method was taken in January 2021, at an automobile manufacturing plant in Shiyan, 656 assemblers with ≥1.0 years of service were selected, the "Musculoskeletal Disorder Questionnaire" was used to investigate the incidence and influencing factors of neck pain. Pearson χ(2) test or trend χ(2) test was used to compare the data rates. The influencing factors of neck pain were analyzed by multivariate logistic regression. Results: The prevalence rate of neck pain (hereinafter referred to as the prevalence rate of neck pain) of automobile assemblers within one year was 53.94% (342/634) . The prevalence of neck pain in women was higher than that in men (69.1% vs 48.6%, P<0.01) . The prevalence of neck pain was related to length of service, self-assessment of fatigue, working hours per week, working in the same workshop, rest days per shift, and accumulated rest time per shift (P<0.05) . Multivariate logistic regression analysis showed that the risk of neck pain in women was 2.434 times higher than that in men; The risk of neck pain increased by 18.9% for each hour of work per week; Rest during work was a protective factor for neck pain. The number of rest per shift increased and the risk of neck pain decreased (r=0.405, 0.311, 0.302, 95%CI=0.205~0.803, 0.169~0.572, 0.142~0.642, P<0.05) . Conclusion: The annual prevalence of neck pain was higher in automobile assemblers. Enterprises should fully consider the influencing factors such as gender, working hours per week and the number of breaks when arranging production.

Objective To explore whether astragaloside IV (AS-IV) can protect radiation-induced kidney injury through toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF-κB)-mediated signaling pathway. Methods The mice were randomly divided into normal control group, DMSO solvent group, irradiation group (IR), IR + AS-IV 20 mg/kg group and IR + AS-IV 40 mg/kg group. One month after intraperitoneal injection of AS-IV, the mice were irradiated with 8 Gy 60Coγ and to the content of serum creatinine (Cr) and uric acid (BUA) in serum were determined, HE and immunohistochemical staining, and expression of TLR4/NF-κB signaling pathway related protein in kidney were performed. Results Compared with the control group, the levels of Cr and BUA in the serum of the radiation group increased significantly (P<0.001), glomerular atrophy and tubular expansion, TLR4 and myeloid differentiation factor 88(MyD88) positive expression increased significantly (P< 0.001), and the expression of TLR4/NF-κB signaling pathway-related proteins[ TLR4, MyD88, NF-κB, interleukin-1 β (IL-Iβ), tumor necrosis factor α (TNF-α)] increased significantly (P< 0.01); AS-IV pretreatment can reduce the content of Cr and BUA in serum (P<0.05, P<0.01 or P<0.001), significantly improve the pathological response caused by radiation, and reduce the expression of TLR4/NF-κB signaling pathway-related proteins (P<0.05 or P<0.01). Conclusion AS-IV may down-regulate the release of inflammatory factors through the TLR4/NF-κB signaling pathway, thereby improving radiation-induced kidney injury in mice and playing a protective role.

In the past 37 years, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has undergone various major transmission routes in China, with the world most complex co-circulating HIV-1 subtypes, even the prevalence is still low. In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection, China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing, which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection. China has been providing free antiretroviral therapy (ART) since 2003, which covered >80% of the identified patients and achieved a viral suppression rate of 91%. To bend the curve of increasing the disease burden of HIV and finally end the epidemic, China should consider constraining HIV spread through sexual transmission, narrowing the gaps in identifying HIV cases, and the long-term effectiveness and safety of ART in the future.
