Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is characterized by congenital vaginal hypoplasia and primordial uterus caused by Müllerian anomalies. Case reports concerning adenomyosis associated with MRKH syndrome are limited, and the formation and intervention of adenomyosis without endometrium are unclear. Here, we present the case of a patient with MRKH syndrome complicated with adenomyosis without endometrium, a hypoechoic solid mass next to the right ovary. According to the intraoperative observation and histopathological examination findings, the mass were diagnosed as adenomyosis of the primordial uterus. Moreover, our report provides insights about its mechanism of occurrence and interventions in MRKH syndrome combined with adenomyosis without endometrium.

The effects of different robust optimization parameters on the doses to organs-at-risk(OAR)and the clinical target volume(CTV)in proton therapy plans for localized prostate cancer are explored for identifying the optimal robust optimization parameters.A retrospective analysis is conducted on 10 cases in which proton plans with a total dose of 76 Gy delivered in 38 fractions are designed.In robust optimization,uncertainties of 3.5%in range and setup errors of 3,5 and 7 mm are considered.After being grouped by setup errors,3 groups of plans are obtained.The effects of setup errors on the doses to CTV and OAR are analyzed,and the robustness of the CTV dose is assessed,including the worst-case values of dosimetric parameters and the passing rates under different scenarios.The results show that as the setup error increased,the doses to OAR tended to rise.Compared with the 3 mm plan group,the 5 mm and 7 mm plan groups experience increases of 1.99%and 5.15%in rectal V70,3.71%and 10.01%in rectal V45,0.93%and 2.55%in bladder V70,and 1.71%and 5.27%in bladder V45,respectively;similar patterns are observed for the doses to sigmoid colon and bulbous urethra,and the differences are statistically significant(P<0.05).In robustness analysis,the CTV D99 in the 5 mm and 7 mm plan groups increases by 0.68 Gy and 0.95 Gy as compared with the 3 mm plan group,with passing rates improving by 7.2%and 9.6%,respectively(passing criterion:D95 receives at least 100%of the prescribed dose),with significant differences(P<0.05).Considering both OAR dose and CTV robustness,the setup error of 5 mm is found to be a reasonable choice for robust optimization in proton therapy plans for localized prostate cancer,as it can effectively balance the enhancement of CTV dose robustness with the control of dose escalation to OAR.

Mosquito-borne viruses,a class of pathogens primarily transmitted by mosquitoes,present severe glo-bal epidemics and pose serious threats to human health.These viruses rely on specific mosquito species for transmi-ssion,and their clinical manifestations vary from mild symptoms to severe complications.Most viruses lack effective treatment agents and vaccines.This review systematically describes the mechanisms of the mosquito-borne virus in-fection transmission,encompassing two key stages:host infection and mosquito infection.During the host infection stage,saliva components of mosquito promote viral invasion and systemic spread within the host by disrupting host hemostasis process,directly interacting with the virus,altering host cell function,and regulating local immune re-sponse,ultimately targeting specific organs and causing disease.During the mosquito infection stage,the targeting of mosquito is regulated by metabolites from host's skin microbiome.Host blood components and mosquito's gut microbiome exert bidirectional regulation in the infection in mosquito's midgut.The viruses break through the mid-gut barrier to enter the hemolymph and further infect the salivary glands.These mechanisms reveal the viruses' adaptive strategies within the host-mosquito ecosystem and emphasize the importance of multifactorial regulation.Future research should focus on molecular interventions,microbial applications,and integrated prevention and con-trol strategies to reduce the risk of mosquito-borne viral transmission.

Objective To explore the significance of mitoxantrone hydrochloride injection and carbon nanoparticles suspension injection in endoscopic radical thyroid cancer surgery.Methods A retrospective analysis was carried out on patients who underwent endoscopic radical surgery for unilateral thyroid cancer at the Depart-ment of General Surgery,Gansu Provincial Central Hospital,from December 2022 to February 2024.The patients were classified into two groups according to the intraoperative tracer employed:the mitoxantrone group and the nanocarbon group.After a 6-month postoperative follow-up,the baseline data of the two patient groups were compared.The intraoperative visualization of lymph nodes and parathyroid glands in both groups was observed.Additionally,the hospitalization costs and the incidence of postoperative complications were compared between the two groups.Results In this study,110 cases were included in the Mitoxantrone group and 126 cases in the nanocarbon group.The staining time of the central lymph nodes was significantly shorter in the nanocarbon group compared to the mitoxantrone group(P<0.05).The blue staining rate of MHI reached 97.5%,while the black staining rate of CNSI was 98.3%.The difference between them was not statistically significant(P>0.05).Regarding the number of central lymph nodes dissected,it was 9.34±0.22 in the Mitoxantrone group and 9.88±0.24 in the nanocarbon group,with no statistically significant difference(P>0.05).Similarly,the parathyroid misdissection rates were 1.8%and 0.8%in the two groups respectively,and no significant statistical difference was observed(P>0.05).Postoperative blood calcium and PTH levels measured at 1 day,1 month,and 6 months did not show any statistically significant differences between the two groups(P>0.05).The incidence of transient hypoparathy-roidism and hypocalcemia was comparable in both groups(P>0.05),and no patients developed permanent hypo-parathyroidism or permanent hoarseness.None of the patients in one Mitoxantrone group experienced postoperative hemorrhage,coeliac leakage,or skin staining.In contrast,in the nanocarbon group,there was one case of postop-erative hemorrhage and one case of coeliac leakage,and two case of skin staining.Conclusions In laparoscopic unilateral thyroid cancer radical surgery,when it comes to lymph node tracing and parathyroid gland protection,no significant disparities were detected between MHI and CNSI.Nevertheless,CNSI exhibits a shorter staining time for central lymph nodes.In contrast,MHI is more manageable,features a faster metabolic rate,and has been demonstrated to be more cost-effective.

Objective: To explore the correlation and lag effects of environmental factors on pediatric respiratory disease visits at hospital, so as to provide scientific basis for disease prediction and optimizing clinical diagnosis and treatment. Methods: Data from 503 889 pediatric respiratory disease outpatient and emergency visits a central hospital in Minhang District of Shanghai between 2017 and 2019, along with concurrent meteorological data were collected. A distributed lag non-linear models (DLNM) was constructed to explore the specific relationship between pediatric respiratory disease consultations and various environmental factors and to quantify the cumulative lag effects of environmental factors on respiratory disease consultations. Results: Among the environmental factors, temperature, fine particulate matter (PM 2.5 ), inhalable particulate matter (PM 10 ), nitrogen dioxide (NO 2), and sulfur dioxide (SO 2) were associated with pediatric respiratory disease visits. After adjusting for temperature, PM 2.5 and PM 10 concentrations did not show significant immediate or lag effects. The relative risk (RR) of pediatric respiratory disease visits increased with rising NO 2 concentrations. When NO 2 concentration ≥55 μg/m 3, significant immediate and lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.05, 1.13, 1.17, and 1.21( P <0.05). The RR values showed an inverted “U” shaped relationship with SO 2 concentrations. When SO 2 concentration ≥5 μg/m 3, significant lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.03 , 1.03, and 1.04 ( P <0.05). Conclusion High concentrations of NO 2 and SO 2 increase the risk of pediatric respiratory disease visits, with observable lag effects.

OBJECTIVE: To observe the clinical efficacy of chicken-claw needling with blade needle for postherpetic neuralgia (PHN). METHODS: A total of 30 patients with PHN were treated with chicken-claw needling with blade needle, the most painful area, costal angle on the same side with the affected intercostal nerve and the midpoint of the line connecting the first two points along the intercostal nerve were selected as treatment points, without needle retained, once a week, a total of 2 times were required. Before and after treatment, the scores of pain visual analogue scale (VAS) and dermatology life quality index (DLQI) were observed, and the clinical efficacy was evaluated after treatment. The recurrence rate of neuralgia was evaluated on the 60th day after treatment. RESULTS: After treatment, the scores of VAS and DLQI were decreased compared with those before treatment (P<0.05). Of 30 patients, 4 cases were cured, 20 cases showed markedly efficacy, 4 cases were improved, 2 cases were ineffective, the total effective rate was 93.3% (28/30). The recurrence rate of neuralgia was 6.7% (2/30). CONCLUSION Chicken-claw needling with blade needle could effectively relieve the pain in patients with PHN, improve the quality of life and reduce the recurrence rate of neuralgia.
