Objective With the gradual advancement of China's lunar exploration program and the construction plan for lunar bases,the technology of docking and assembling mobile lunar modules has become an important means for long-term habitation of lunar mobile modules and the construction of lunar bases in the future.Therefore,the design of flexible docking structures between lunar modules has become an urgent problem to be solved.Methods To address the issue of precise docking of mobile lunar modules on the lunar surface,which is severely affected by the uneven terrain and settlement,this paper proposes a flexible docking segment structure composed of a skin and a skeleton.Results The structure deforms to meet the large tolerance docking range required between lunar mobile modules.In terms of skin design,the docking segment structure uses a variety of composite materials to form a flexible skin to cope with the lunar surface environment problems such as radiation,wide temperature variations,and high-speed meteoroid impacts.In terms of skeleton design,a corrugated skeleton structure scheme is presented.Conclusion Based on Ansys and Adams software,static and dynamic simulation analyses of the skeleton structure were conducted,verifying the feasibility of this structure as a flexible docking structure between lunar modules.

Background and objective Isoliquiritigenin(ISL)is an important pharmacological constituent of Glycyrrhiza glabra,which possesses a range of physiological and pharmacological activities,as well as significant antitumor ac-tivity,and can be used as a potential drug for targeted cancer therapy.LINC01503 is an oncogene,which has been closely asso-ciated with the malignant biological processes of many cancers.The aim of this study was to investigate the effects of ISL on the proliferation,apoptosis,invasion and migration oflung squamous carcinoma cells by regulating LINC01503.Methods Plasma was collected from lung squamous carcinoma patients and healthy individuals treated at Tangshan People's Hospital from Janu-ary 2021 to December 2022.The expression of LINC01503 in lung squamous carcinoma plasma,tissues and cells was detected by real-time quantitative fluorescence polymerase chain reaction(qRT-PCR).Lung squamous carcinoma cells were treated with different concentrations of ISL for 24 h,and LINC01503 expression was detected by qRT-PCR.The cells were treated in groups:si-NC group,si-LINC01503 group,DMSO(0.1％dimethyl sulfone)group,ISL group,pc DNA3.1(+)-NC group,pc DNA3.1(+)-LINC01503 group,ISL+pc DNA3.1(+)-NC group and ISL+pc DNA3.1(+)-LINC01503 groups.CCK-8 assay,clone formation assay,flow cytometry,Transwell assay and scratch assay were used to explore the effect of LINC01503 on the functional phenotype of lung squamous carcinoma cells.Results Fluorescence in situ hybridization results showed that the average fluorescence intensity of LINC01503 in tissue microarrays of lung squamous carcinoma patients was higher than that in paracancerous tissues(P＜0.05).The expression of LINC01503 in the plasma of patients with lung squamous carcinoma was higher than that in the plasma of healthy individuals(P＜0.05).Knockdown of LINC01503 inhibited the proliferation,invasion and migration of lung squamous carcinoma cells and promoted apoptosis(P＜0.05).ISL inhibited the proliferation,invasion,migration and promoted apoptosis of lung squamous carcinoma cells(P＜0.05).Overexpression of LINC01503 followed by intervention with ISL reversed the promotional effect of overexpression of LINC01503 on the proliferation,invasion and migration of lung squamous carcinoma cells as well as the inhibitory effect on apoptosis(P＜0.05).Conclusion LINC01503 was highly expressed in lung squamous carcinoma,and LINC01503 could promote the proliferation,invasion and migra-tion of lung squamous carcinoma cells and inhibit the apoptosis,ISL could inhibit the proliferation,invasion and migration of lung squamous carcinoma cells and promote apoptosis of lung squamous carcinoma cells by regulating the expression of LINC01503.

Objective:To analyze the influencing factors of urinary infection after radical cystectomy in elderly patients with bladder cancer.Methods:A retrospective study was conducted to collect the clinical data of 56 elderly patients with bladder cancer who developed urinary infection after radical cystectomy in the Second Affiliated Hospital of Xi′an Jiaotong University from March 2020 to February 2023. All patients were included in the case group. A total of 168 patients without urinary infection after radical cystectomy were collected at a ratio of 1∶3 into the control group. Baseline data and perioperative data were collected, and Logistic regression was used to analyze the influencing factors of urinary infection after radical cystectomy in elderly patients with bladder cancer.Results:Single factor analysis showed that the diabetes proportion, hydronephrosis proportion, nutrition risk proportion, inhalation anesthesia proportion, senile weakness proportion, stress hyperglycemia proportion, albumin (ALB) <35 g/L proportion and urine bag replacement time in the case group were significantly higher than those in the control group: 66.07% (37/56) vs. 44.64% (75/168), 69.64% (39/56) vs. 46.43% (78/168), 66.07% (37/56) vs. 41.67% (70/168), 73.21% (41/56) vs. 48.81% (82/168), 55.36% (31/56) vs. 35.12% (59/168), 41.07% (23/56) vs. 20.24% (34/168), 55.36% (31/56) vs. 36.90% (62/168), (7.52 ± 1.65) d vs. (6.62 ± 1.44) d, and there were statistical differences ( P<0.05). Logistic regression analysis showed that nutrition risk, inhalation anesthesia, stress hyperglycemia and senile weakness were independent factors of urinary infection after radical cystectomy in elderly patients with bladder cancer ( P<0.05). Conclusions:Urinary infection after radical cystectomy in the elderly patients with bladder cancer is closely related to nutritional risk, inhalation anesthesia, stress hyperglycemia and senile weakness. Attention to the above factors and symptomatic intervention are important for prevention and treatment of urinary infection.

Objective To investigate the effect of different premolar extraction patterns on Bolton index and occlusal relationship of skeletal Class Ⅱmalocclusion.Methods The plaster models of 62 patients with skeletal ClassⅡmalocclusion were selected and con-verted into digital models by iTeroElement scanner.Each model was simulated by the four premolar extraction pattrens,and tooth ar-rangement test was performed after tooth extraction.The Bolton index before and after tooth extraction was calculated,and the occlusal relationship after tooth arrangement was evaluated to explore its law.Results All the four premolar extraction patterns resulted in a significant decrease in the Bolton index over-all ratio in skeletal ClassⅡpatients,and compared with the extraction patterns of 4/4 and 4/5,the patterns of 5/4 and 5/5 resulted in a greater decrease in the Bolton index over-all ratio(P＜0.001).For skeletal classⅡmal-occlusion,the tooth arrangement test was conducted on the basis of establishing the neutral relationship of first molar.The average value of anterior teeth over-jet obtained by patterns of 4/4 and 4/5 was within the normal range(＜3 mm).The average value obtained by pat-terns of 5/4 and 5/5 was greater than the normal range(＞3 mm),and the difference was statistically significant(P＜0.001).Conclu-sion The premolar extraction patterns of 4/4 and 4/5 are more conducive to normalizing the Bolton index over-all ratio and establis-hing the better occlusal relationship for skeletal Class Ⅱ malocclusion.

Objective To investigate the value of echocardiography in assessing right ventricular function of primary light-chain amyloidosis(AL)-cardiac amyloidosis(CA)patients.Methods A total of 25 patients biopsy diagnosed as AL-CA,who were admitted to the First Affiliated Hospital of Wenzhou Medical University from January 2018 to December 2021,were enrolled in this study as amyloidosis group.And 25 heathy volunteers were set as control group.The routine right ventricular morphology and functional parameters were acquired by standard echocardiography.Right ventricular global longitudinal strain(RVGLS)and right ventricular free wall longitudinal strain(RVfwLS)were obtained by two-dimensional speckle tracking imagine.Tricuspid annular plane systolic excursion(TAPSE)/pulmonary artery systolic pressure(PASP),RVGLS/PASP,RVfwLS/PASP ratio were calculated as the noninvasively parameters of right ventricular-pulmonary artery coupling.Results ①Compared with control group,patients in amyloidosis group showed significantly larger right heart size,and significantly thicker right ventricular free wall[(7.16±1.84)mm vs.(3.76±0.66)mm],the difference was statistically significant(P<0.001).②Compared with control group,RVGLS[(17.43±2.45)%vs.(23.22±3.73)%]and RVfwLS[(18.44±2.10)%vs.(22.62±3.64)%]were significantly impaired in amyloidosis group,the difference was statistically significant(P<0.001).The ratios of TAPSE/PASP,RVGLS/PASP,RVfwLS/PASP were found to be lower in amyloidosis group,the difference was statistically significant(P<0.001).③TAPSE/PASP showed mild correlations with N-terminal brain natriuretic peptide precursor(NT-proBNP),highly sensitive T cardiac troponin(hs-TNT)(r=0.45 and 0.40)there were statistically significant(P<0.05).Conclusion Echocardiography can effectively evaluate the right heart function impairment in AL-CA patients,providing valuable information for a deeper understanding of the pathological and physiological mechanisms of the disease.

Abstract OBJECTIVE To clarify the resource status and diversity of endemic medicinal plants in Shaanxi province. METHODS The species specificity, species composition, faunal composition, family and genus types, medicinal value and endangerment degree of endemic medicinal plants in Shaanxi province were studied by literature review.RESULTS There were 713 species of 331 genera and 101 families endemic to Chinese medicinal plants in the study area. Fifteen species were naturally distributed only in Shaanxi province, and the remaining 698 species were also naturally distributed in other provinces of China. Among the 713 species, 233 species(69 families, 159 genera) were not collected from the fourth resource census in Shaanxi province. There were 11 species of pteridophytes in 7 families and 11 genera, 14 species of gymnosperms in 4 families and 10 genera, 627 species of dicotyledons in 82 families and 278 genera, and 59 species of monocots in 8 families and 32 genera. The endemic life forms of medicinal plants in the study area were mostly herbaceous, followed by shrubs and trees, and semi-shrubs and epiphytes accounted for the least. There were 9 families with ≥ 20 species and 4 families with ≥ 10 species in the study area. The 90 families belonging to the endemic species of medicinal plants in Shaanxi province were divided into 13 distribution types and 9 variations, and the tropical distribution(2-7 categories) had a total of 34 families. There were 5 endemic species of medicinal plants in the study area under the national class I key protection, and 14 species under the national class II key protection. There were 26 species of plants under local key protection in Shaanxi province. There were 21 plants that could be used as original plants for medicinal materials included in the Pharmacopoeia of the People's Republic of China(2020 edition). CONCLUSION The endemic species of medicinal plants in Shaanxi province are rich in resources and have good medicinal value. However, the growing environment of some plants is harsh and human damage is serious. Multiple protection measures should be taken to maintain the species diversity and sustainable development of resources in the study area.

ObjectiveTo analyze the epidemiological characteristics of varicella in Minhang District， Shanghai from 2013 to 2022， and to evaluate the impact of adjusting the varicella vaccination program to a two-dose regimen and its inclusion in the Shanghai immunization program on the incidence of varicella. MethodsData on reported varicella cases from 2013 to 2022 in Minhang District were collected. Interrupted time series analysis and segmented regression models were used to analyze the changes in varicella incidence before and after the adjustment of varicella immunization strategies. ResultsFrom 2013 to 2022， the average annual incidence of varicella was 76.58/100 000， with the highest incidence in 2017 （119.21/100 000） and the lowest in 2022 （27.02/100 000）. The varicella incidence exhibited seasonal patterns with peaks occurring from March to June and October to January of the following year. Prior to the adjustment of varicella immunization strategies （2013‒2017）， the varicella incidence showed an upward trend （z=2.20， P=0.03）， while after the adjustment （2018‒2022）， a adownward trend was observed （2018‒2022） （z=-2.25， P=0.02）. Interrupted time series analysis showed that following the adjustment of varicella immunization strategies， an immediate change of -33.91/100 000 （t=-4.35， P<0.001） in varicella incidence was observed， and the incidence slope was -17.59/100 000 with a decline of 28.61/100 000 （t=-12.16， P<0.001） compared to before inclusion. ConclusionThe incidence of varicella in Minhang District， Shanghai from 2013 to 2022 exhibits distinct seasonal patterns. After adjusting the varicella vaccination program to a two-dose regimen and incorporating it into the immunization program， the second dose of varicella vaccine administration substantially increases. As a result， the rising trend of varicella incidence is effectively controlled， and the incidence level decreases significantly， showing a sustained downward trend.

Tripartite motif (TRIM) family proteins are important effectors of innate immunity against viral infections. Here we identified TRIM35 as a regulator of TRAF3 activation. Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon (IFN) in response to viral infection. Trim35-deficient mice were more susceptible to influenza A virus (IAV) infection than were wild-type mice. TRIM35 promoted the RIG-I-mediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1. IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3. TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2, thereby antagonizing its suppression of TRAF3 activation. Our in vitro and in vivo findings thus reveal novel roles of TRIM35, through catalyzing Lys63- or Lys48-linked polyubiquitination, in RIG-I antiviral immunity and mechanism of defense against IAV infection.

Objective: To explore the mediation mechanism of coronary artery lesion among both male and female Kawasaki disease (KD) children. Methods: Children with KD that hospitalized in the Wenzhou Medical University affiliated Yuying Children’s Hospital from January 2009 to December 2014, were included in this study. Differences on demographical characteristics, clinical manifestations, laboratory indicators, regimen and time of treatment, results from pre/post echocardiography and treatment between male and female patients, were compared. The independent effect of gender on the risk of coronary artery lesions (CAL) was evaluated, and the mediating effect of BMI, visiting time and KD type on the association between gender and CAL were also studied. Results: The average BMI level of male patients was higher than that of female patients. The difference was statistically significant (P<0.001). The prevalence of overweight among male patients (20.9%) was higher than female (14.1%). The difference was statistically significant (P=0.011). Data from the multivariate logistic regression analysis confirmed that the incidence of CAL in male patients was higher than that in female patients (aOR=1.50, 95%CI: 1.06-2.12) but the CAL was mainly different before on the immunoglobulin therapy. Results from the mediation analysis showed that BMI was an important mediator in the association between gender and CAL, with the indirect effect as 1.05 (95%CI: 1.01- 1.10) and the proportion mediated as 13.0%. Conclusions Male patients presented higher incidence of CAL but was mainly reflected in the difference of CAL before the treatment. BMI was probably an important mediator related to the association between gender and CAL.
