Objective: To analyze the association between insufficient sleep and score of depressive symptoms among junior and senior high school students, so as to provide a scientific reference for targeted early intervention measures of adolescents depressive symptoms. Methods: From September to November 2023, a stratified cluster random sampling method was used to select 96 080 junior and senior high school students from 409 schools in 113 districts and counties in Shaanxi Province. A questionnaire survey was conducted using the 2023 Shaanxi Provincial Common Student Diseases and Health Influencing Factors Survey Form, and their height and weight were measured. Propensity score (PS) matched (1∶1) analysis was used to match participants with insufficient sleep to those sufficient sleep students. Through the gradual correction of the confounders, three multilevel linear models were established to analyze the association between insufficient sleep and depressive symptoms score, and subgroup analysis was conducted afterward. Results: A total of 70 135 (73.00%) students had insufficient sleep. After PS matching, 25 894 pairs were matched. Before PS matching, after adjusting for gender, educational stage, region, adolescent characteristics, boarding status, smoking, alcohol consumption, outdoor activities and body mass index grouping, linear regression analysis results showed that compared with students who got adequate sleep, students who lacked sleep had an increase of 1.39 scores ( B=1.39, 95%CI =1.28-1.51) in depressive symptoms; after PS matching, students with insufficient sleep got an increase of 1.32 scores ( B=1.32, 95%CI =1.17- 1.45 ) in depressive symptoms score compared with those who had adequate sleep (both P <0.05). Conclusions The insufficient sleep is associated with the increase of the depressive symptoms score of junior and senior high school students. It is recommended that junior and senior high school students should keep a good sleeping habit, so as to reduce the prevalence of depressive symptoms.

AIM: To evaluate safety, efficacy, visual quality, and patient satisfaction after optimized monovision Q-value-customized femtosecond laser-assisted in situ keratomileusis(FS-LASIK)for myopia, astigmatism, and presbyopia. METHODS: This prospective study enrolled patients suffering myopia, astigmatism, and presbyopia. At 1 y post operation, uncorrected distance, intermediate and near visual acuity(UDVA, UIVA, UNVA), refraction, corneal higher order aberrations(HOAs), Q value, objective visual quality, and near stereoacuity were evaluated. The impact of surgery on patients' living quality and their satisfaction were evaluated based on National Eye Institute Refractive Error Quality of Life Instrument(NEI RQL)scores at 1-year follow-up.RESULTS:The study enrolled 36 patients(72 eyes)including 12 males(33%)and 24 females(67%)with an average age of 46.03±3.60(range 40-53)y. One year postoperatively, 97% of patients achieved binocular UDVA of 1.0 or better, 89% achieved UIVA of 0.63 or better, and 97% achieved UNVA of 1.0 or better. The spherical equivalent refraction(SE)in dominant eye within ±1.00 D was 100%. SE in non-dominant eyes was uncorrected compared with the preoperative target correction, with a mean difference of -0.27±0.34 D before and after surgery(P<0.001). while in the non-dominant eyes, the anterior corneal Q-value within the 5 mm zone increased negatively compared with the preoperative value(-0.33±0.24 vs -0.21±0.09, P<0.001). In the non-dominant eye, spherical aberration and longitudinal spherical aberration were lower than preoperative values(both P<0.001). Besides, there were no significant changes in objective scatter index(OSI), modulation transfer function cutoff frequency(MTF cut off)and Strehl ratio(SR)in both dominant and non-dominant eyes(all P>0.05), and the near stereoacuity was better after surgery(P=0.007). Additionally, the patient satisfaction rate with the surgery was 94%, the satisfaction rates for UDVA and UNVA were both 98%. The 11% of patients required to wear low-diopter glasses when driving at night.CONCLUSION:Optimized monovision Q-value-customised FS-LASIK is a safe and effective procedure for correcting myopia, astigmatism, and presbyopia. It provides favorable subjective and objective visual quality and high patient satisfaction. The under correction in non-dominant eyes is observed, indicating the further optimization of nomogram is needed.

OBJECTIVE: To retrospectively analyze the characteristics and influencing factors of COVID-19 infection in patients with multiple myeloma (MM) who underwent autologous hematopoietic stem cell transplantation (AHSCT). METHODS: The clinical data of MM patients who underwent AHSCT in Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from May 26, 2021 to December 26, 2022 were collected. The onset of COVID-19 infection, corresponding symptoms and laboratory tests were followed up in outpatient or by the means of telephone contact and online questionnaires. Related analysis was then performed. RESULTS: This study included 96 patients, and 72 cases among them were infected with COVID-19 while 24 cases were uninfected. Logistic regression analysis showed that vaccination did not significantly reduce the risk of COVID-19 infection, but patients who received two doses of the vaccine had a lower risk of developing moderate and severe disease than those who did not receive or received one dose (OR =0.06, P =0.029). Patients who received daratumumab before had a higher risk of COVID-19 infection (OR =5.78, P =0.039), while those with a history of immunomodulatory drugs (IMiDs) had the opposite effect (OR =0.31, P =0.028). The use of both drugs did not affect the severity of COVID-19 infection. CONCLUSION For MM patients undergoing AHSCT as first-line chemotherapy, COVID-19 vaccination does not significantly reduce the infection rate, but it plays a role in preventing moderate and severe cases. The application of antineoplastic drugs with different mechanisms has a certain impact on the susceptibility to the COVID-19, which should be considered comprehensively when creating treatment plans.

OBJECTIVES: To investigate the risk factors of overall postoperative complications in elderly patients undergoing gastrointestinal surgeries. METHODS: This study was conducted among a total of 1388 elderly patients, who underwent elective gastrointestinal surgeries at 17 centers across China between April, 2020 and April, 2022. The primary outcome was the incidence of postoperative complications within 30 days, including procedure-related, neuropsychiatric, respiratory, cardiovascular, and gastrointestinal complications as well as acute kidney injury. Baseline characteristics, preoperative psychological and functional status, intraoperative anesthesia and surgical factors, intraoperative medication, use of nerve block, and postoperative analgesia methods were compared between the patients experiencing one or more postoperative complications and those without complications. Univariate and multivariate logistic regression analyses were performed to identify the independent risk factors for postoperative complications. The relationship between postoperative acute pain and each type of complication were explored. RESULTS: The incidence of overall postoperative complications was 50.8% (705/1388) in these patients. Multivariate analysis showed that age (OR: 1.026; 95% CI: 1.006-1.046), prognostic nutritional index (OR: 0.998; 95% CI: 0.997-1.000), preoperative EuroQol-5 dimensions score (OR: 0.094; 95% CI: 0.018-0.500), blood loss (OR: 1.002; 95% CI: 1.001-1.003), and acute postoperative pain (OR: 1.308; 95% CI: 1.033-1.657) were significantly associated with the occurrence of postoperative complications. Specifically, patients experiencing severe postoperative pain had a significantly higher incidence of neuropsychiatric (27.2% vs 19.8%), procedure-related (17.3% vs 10.2%), and cardiovascular complications (3.6% vs 1.7%). CONCLUSIONS An advanced age, a low preoperative nutritional index, a poor quality of life score, a greater volume of intraoperative blood loss, and acute postoperative pain are independent risk factors for postoperative complications in elderly patients undergoing gastrointestinal surgeries. There is a significant association between acute postoperative pain and multi-system complications.

OBJECTIVE: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture. METHODS: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve. RESULTS: Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats. CONCLUSION Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

OBJECTIVE: Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA. METHODS: This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance. RESULTS: The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m²) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m²). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA. CONCLUSION Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.

Brasilicardin A, a diterpene glycoside isolated from pathogenic actinomycete Nocardia brasiliensis IFM 0406, has become a novel immunosuppressant candidate due to its significant immunosuppressive activity, low toxicity and unique mechanism of action. However, brasilicardin A and its analogues have become a research hotspot to the development of this promising immunosuppressant because of the low-yield production in the natural pathogenic producer and the synthetically challenging skeleton. According to the reported biosynthetic pathway of brasilicardin A, the function of involved diterpene synthase was analyzed by bioinformatics. Then the genes bra1-5 that synthesize the brasilicardin A skeleton were directionally amplified from the pathogenic strain N. brasiliensis IFM 0406, and heterologous expression was achieved successfully in Streptomyces albus R1. The compounds were isolated and purified by using various column chromatographies including silica gel column chromatography and semi-preparative HPLC. Six new brasilicardins were established and named brasilicardin H-M. The activity of brasilicardins was screened using lipopolysaccharide (LPS)-activated mouse primary macrophage inflammation model. Brasilicardin H-M exhibited good inhibitory activity on nitric oxide (NO) release with IC₅₀ values of 28.24 ± 3.70, 37.44 ± 2.00, 39.85 ± 4.02, 26.77 ± 4.40, 65.25 ± 1.48 and 15.24 ± 2.72 μmol·L^-1, respectively (indomethacin as the positive control with IC₅₀ value of 34.28 ± 4.10 μmol·L^-1). The results indicated that six compounds had potential anti-inflammatory activity. This study laid a foundation for the elucidation of the brasilicardin A biosynthetic pathway and evaluation of the structure-activity relationship as well as new drug developments.

Objective To investigate the effects and mechanism of β2 adrenergic receptors(ADRB2)in ferroptosis and autophagy induced by erastin(Era)in prostate cancer.Methods PC-3 cells were infected with lentivirus or control and set to sh-NC group(normal culture),sh-NC+Era group(10 μmol/L Era treatment for 24 h),sh-ADRB2 group(normal culture),and sh-ADRB2+Era group(10 μmol/L Era treatment for 24 h).The viability of the cells treated with Era and ferrostatin-1(Fer-1)was measured by CCK-8 assay.The cell morphology was analyzed by transmission electron microscopy.The malondialdehyde(MDA)content was measured by the Lipid Oxidation Detection Kit and the iron level by Iron Colorimetric Assay.Western blotting was used to detect the expressions of cystine-glutamate exchanger(XCT),ferritin heavy chain 1(FTH1),glutathione peroxidase 4(GPX4),p62,LC3,JNK,c-Jun,and p-c-Jun.PC-3 cells with ADRB2 knockdown were injected into nude mice to construct a xenograft model and then treated with Era.The animals were divided into sh-NC group,sh-NC+Era group,sh-ADRB2 group,and sh-ADRB2+Era group,with 4 mice in each group.The tumor volumes were recorded every other day and the final tumor weight was measured at study termination.The expressions of ADRB2,JNK,c-Jun,and p-c-Jun were detected by immunohistochemistry(IHC).Results The viability of PC-3 cells decreased after Era treatment(P<0.01)and recovered after Fer-1 treatment(P<0.01).Morphological changes of ferroptosis and autophagy were observed in Era-treated cells,and MDA and iron ion contents up-regulated(P<0.05 or P<0.01).Knockdown of ADRB2 and Era treatment further inhibited PC-3 cell viability(P<0.05),and MDA and iron ion contents up-regulated(P<0.01).The expressions of ferroptosis-related proteins FTH1,XCT,GPX4,and LC3 down-regulated(P<0.05 or P<0.05),p62 and JNK pathway-related proteins JNK,c-Jun,and p-c-Jun were up-regulated(P<0.01).After JNK inhibitor treatment,the expressions of FTH1,XCT,and LC3 increased,and p62 decreased(P<0.01).In the PC-3 xenograft model,tumor volume in sh-ADRB2+Era group was significantly smaller than those in sh-NC+Era group and sh-ADBR2 group(P<0.05 or P<0.01).IHC showed that compared with sh-NC group,ADRB2 protein expression level was down-regulated in sh-ADRB2 group(P<0.05),while JNK,c-Jun,and p-c-Jun protein expression levels were elevated(P<0.01).Compared with sh-NC+Era group,the ADRB2 protein expression level in sh-ADRB2+Era group was down-regulated,while JNK,c-Jun,and p-c-Jun protein expression levels were up-regulated(P<0.05).Conclusion ADRB2 regulated ferroptosis and autophagy induced by Era via JNK/c-Jun pathway in prostate cancer.

Objective To explore the effects of circ_100284 in affecting the invasion of esophageal squamous cell carcinoma(ESCC)cells and their sensitivity to 5-fluorouracil(5-FU)chemotherapy via regulating miR-217/mitogen-activated protein kinase 1(MAPK1)acting as a competing endogenous RNA(ceRNA).Methods The bioinformatics approach was used to analyze the differentially expressed circRNAs in ESCC.qRT-PCR was used to detect the expression of circ_100284 in ESCC tissues and cells.The 5-FU-resistant KYSE450 cell line(KYSE45-R)was established by increasing concentrations of 5-FU.The IC50 of 5-FU in KYSE450 and KYSE450-R cells was determined through MTT assay.qRT-PCR was used to detect the expression of circ_100284,miR-217,and MAPK1 mRNA in KYSE450 and KYSE450-R cells,while Western blotting detecting the protein expression of MAPK1.In the experiments with KYSE450-R cells,we set up the following groups:(1)blank group(without treatment),si-NC group(transfected with si-NC),si-circ_100284 group(transfected with si-circ_100284),pc-Control group(transfected with pc-Control),pc-circ_100284 group(transfected with pc-circ_100284),pc-circ_100284+mimic NC group(transfected with pc-circ_100284 and mimic NC),and pc-circ_100284+miR-217 mimic group(transfected with pc-circ_100284 and miR-217 mimic).These groups were subjected to MTT assay to detect cell viability,Transwell assay to detect cell invasion,and flow cytometry to detect cell apoptosis.(2)Blank group(without treatment),si-NC group(transfected with si-MAPK1 negative control),si-MAPK1 group(transfected with si-MAPK1),si-MAPK1+inhibitor NC group(transfected with si-MAPK1 and inhibitor NC),and si-MAPK1+miR-217 inhibitor group(transfected with si-MAPK1 and miR-217 inhibitor).We detected the mRNA and protein expression of MAPK1 using qRT-PCR and Western blotting.We evaluated cell viability using MTT assay,invasion with Transwell assay,and apoptosis by flow cytometry.circ_100284-WT or circ_100284-MUT reporter plasmids,as well as MAPK1-WT or MAPK1-MUT reporter plasmids,were co-transfected with miR-NC or miR-217 mimic into KYSE450-R cells for 48 h,and dual luciferase reporter assay was used to measure luciferase activity.Results The bioinformatics analysis revealed significant upregulation of circ_100284 in ESCC.Compared with adjacent normal tissues,the expression of circ_100284 in ESCC tissues is enhanced(P<0.05);compared with the HECC cells,the TE-11,ECA109 and KYSE450 ESCC cell lines showed enhanced expression of circ_100284(P<0.05).Compared with the KYSE450 cells,KYSE450-R cells demonstrated increased IC50 with enhanced expression of circ_100284 and MAPK1 but suppressed expression of miR-217(P<0.05).Compared with the si-NC group,the si-circ_100284 group demonstrated inhibited invasion and proliferation of cells with increased apoptosis(P<0.05).Compared with pc-Control group,the invasion and proliferation of cells in the pc-circ_100284 group are increased,and cell apoptosis is decreased(P<0.05).Over-expression of miR-217 reversed the malignant biological behavior of ESCC cells induced by pc-circ_100284(P<0.05).Compared with si-NC group,in the si-MAPK1 group,we observed decreased cell invasion and proliferation,and increased apoptosis(P<0.05),but miR-217 inhibitor reversed the effect of si-MAPK1 on the biological behavior of ESCC cells(P<0.05).The targeting relationship of circ_100284 and miR-217,miR-217 and MAPK1 is confirmed.Conclusion circ_100284 promotes ESCC cell invasion by regulating miR-217/MAPK1,inhibits the chemosensitivity of ESCC cells to 5-FU,and acts as a tumor-promoting factor in ESCC.
