Background and objective Transcription factor(TF)can bind specific sequences that either promotes or represses the transcription of target genes,and exerts important effects on tumorigenesis,migration,invasion.Staphylococcal nuclease-containing structural domain 1(SND1),which is a transcriptional co-activator,is considered as a promising target for tumor therapy.However,its role in lung adenocarcinoma(LUAD)remains unclear.This study aims to explore the role of SND1 in LUAD.Methods Data from The Cancer Genome Atlas(TCGA),Gene Expression Omnibus(GEO),Clinical Pro-teomic Tumor Analysis Consortium(CPTAC),and Human Protein Atlas(HPA)database was obtained to explore the associa-tion between SND1 and the prognosis,as well as the immune cell infiltration,and subcellular localization in LUAD tissues.Furthermore,the functional role of SND1 in LUAD was verified in vitro.EdU assay,CCK-8 assay,flow cytometry,scratch assay,Transwell assay and Western blot were performed.Results SND1 was found to be upregulated and high expression of SND1 is correlated with poor prognosis of LUAD patients.In addition,SND1 was predominantly present in the cytoplasm of LUAD cells.Enrichment analysis showed that SND1 was closely associated with the cell cycle,as well as DNA replication,and chro-mosome segregation.Immune infiltration analysis showed that SND1 was closely associated with various immune cell popula-tions,including T cells,B cells,cytotoxic cells and dendritic cells.In vitro studies demonstrated that silencing of SND1 inhib-ited cell proliferation,invasion and migration of LUAD cells.Besides,cell cycle was blocked at G,phase by down-regulating SND1.Conclusion SND1 might be an important prognostic biomarker of LUAD and may promote LUAD cells proliferation and migration.

Objective:To explore an early mobilization plan for oral cancer patients after free flap reconstruction and evaluate the application effect of the plan.Methods:This study was a prospective randomized controlled trial. A total of 173 patients undergoing free flap reconstruction surgery from December 2018 to December 2021 in the second ward of Peking University School and Hospital of Stomatology were selected. The patients were randomly divided into the control group (87 cases) and the intervention group (86 cases) by cluster randomized grouping. The control group received the routine nursing plan, that was, head immobilization for 4 days after surgery, and patients performed sat up and off-bed activity on the 5th day. The intervention group received the early mobilization plan, that was, patients sat up on the 2nd day after surgery and performed off-bed activity on the 3rd day. The incidence of vascular compromise, postoperative complications, sleep time in the first 5 days after surgery, catheter removal time, hospitalization duration and expenses were compared between the two groups.Results:The incidence of postoperative pulmonary infection, the daily sleep time in the first 5 days after surgery, the time for removing nasogastric tube, trachea cannula, and urinary catheter were 7.0%(6/86), (5.0 ± 1.0) h/d, (11.8 ± 7.3) d, (6.1 ± 3.2) d, (3.6 ± 0.6) d in the intervention group, and 13.8%(12/87), (4.4 ± 1.3) h/d, (14.2 ± 5.8) d, (7.3 ± 1.7) d, (4.0 ± 0.9) d in the control group, all differences were statistically significant ( χ2 = 3.89, t values were -3.57 - -2.44, all P<0.05). There was no significant difference in the incidence of rascular compromise, hospitalization duration and expenses between the two groups (all P>0.05). Conclusions:For patients undergoing free tissue flap reconstruction, it is safe to sit up on the 2nd day and get out of bed on the 3rd day, which can reduce the incidence of pulmonary infection, improve patient sleep, and shorten the indwelling time of nasogastric tube, trachea cannula and urinary catheter.

Depressive disorder ranks as a major bur-den of disease worldwide,yet the current antidepressant medications are limited by frequent non-responsiveness and significant side effects.The lateral septum(LS)is thought to control of depression,however,the cellular and circuit substrates are largely unknown.Here,we identified a subpopulation of LS GABAergic adenosine A2A receptors(A2AR)-positive neurons mediating depres-sive symptoms via direct projects to the lateral habenula(LHb)and the dorsomedial hypothalamus(DMH).Activa-tion of A2AR in the LS augmented the spiking frequency of A2AR-positive neurons leading to a decreased activation of surrounding neurons and the bi-directional manipula-tion of LS-A2AR activity demonstrated that LS-A2ARs are necessary and sufficient to trigger depressive pheno-types.Thus,the optogenetic modulation(stimulation or inhibition)of LS-A2AR-positive neuronal activity or LS-A2AR-positive neurons projection terminals to the LHb or DMH,phenocopied depressive behaviors.Moreover,A2AR are upregulated in the LS in two male mouse mod-els of repeated stress-induced depression.This identifica-tion that aberrantly increased A2AR signaling in the LS is a critical upstream regulator of repeated stress-induced depressive-like behaviors provides a neurophysiological and circuit-based justification of the antidepressant poten-tial of A2AR antagonists,prompting their clinical transla-tion.

The progressive destruction of condylar cartilage is a hallmark of the temporomandibular joint (TMJ) osteoarthritis (OA); however, its mechanism is incompletely understood. Here, we show that Kindlin-2, a key focal adhesion protein, is strongly detected in cells of mandibular condylar cartilage in mice. We find that genetic ablation of Kindlin-2 in aggrecan-expressing condylar chondrocytes induces multiple spontaneous osteoarthritic lesions, including progressive cartilage loss and deformation, surface fissures, and ectopic cartilage and bone formation in TMJ. Kindlin-2 loss significantly downregulates the expression of aggrecan, Col2a1 and Proteoglycan 4 (Prg4), all anabolic extracellular matrix proteins, and promotes catabolic metabolism in TMJ cartilage by inducing expression of Runx2 and Mmp13 in condylar chondrocytes. Kindlin-2 loss decreases TMJ chondrocyte proliferation in condylar cartilages. Furthermore, Kindlin-2 loss promotes the release of cytochrome c as well as caspase 3 activation, and accelerates chondrocyte apoptosis in vitro and TMJ. Collectively, these findings reveal a crucial role of Kindlin-2 in condylar chondrocytes to maintain TMJ homeostasis.

OBJECTIVE To explore the effects of Citrus medica before and after being steamed on blood metabolism and dryness indexes in rats. METHODS Twenty-four SD rats were randomly divided into blank group, C. medica group (2.4 g/kg), processed C. medica group (2.4 g/kg), Citrus aurantium group (positive control, 1.2 g/kg), with 6 rats in each group. After 5 weeks of continuous administration, the body weight, food intake, water intake and urine volume were observed dynamically. The content of aquaporin 3 (AQP3) in serum was detected. The metabolic profile of rat serum samples was analyzed by liquid chromatography-mass spectrometry. Principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) were used to screen differential metabolites, and screened differential metabolites were mapped to the KEGG database for pathway analysis. RESULTS The body weight of rats in each group increased slowly; the food intake and water intake of processed C. medica group tended to be higher than those in C. medica group and C. aurantium group, but there was no significant difference among those groups (P>0.05). On the 21st day of administration, compared with C. aurantium group, the urine volume of processed C. medica group was significantly increased (P<0.05), the serum AQP3 content of processed C. medica group was significantly decreased (P<0.05), and were close to those of blank group. According to the metabonomic study, C. medica mainly affected the lipids metabolism, and processed C. medica mainly affected the amino acid metabolism. The differential metabolites pathway between C. medica and processed C. medica involved the metabolism of cysteine and methionine, metabolism of glycine, serine and threonine, and metabolism of taurine and hypotaurine. CONCLUSIONS Processed C. medica might relieve the dryness of C. medica by affecting adenosine phosphate-protein kinase A. The content of AQP3 in serum can be used as the 52 evaluation index for the dryness of C. medica before and after processing. The effects of C. medica and processed C. medica on endogenous metabolites in rat serum are quite different,especially in the aspect of lipid metabolism.

Objective:To assess the efficacy and safety of 100 units of botulinum toxin A (BTX-A) intradetrusor injection in patients with overactive bladder.Methods:From April 2016 to December 2018, 17 tertiary hospitals were selected to participate in this prospective, multicenter, randomized, double-blind, placebo-controlled study. Two phases of study were conducted: the primary phase and the extended phase. This study enrolled patients aged 18 to 75 years who had been inadequately managed by anticholinergic therapy (insufficient efficacy or intolerable side effects) and had spontaneous voiding with overactive bladder. Exclusion criteria included patients with severe cardiac, renal and hepatic disorders, patients with previous botulinum toxin treatment for 6 months or allergic to BTX-A, patients with urinary tract infections, patients with urinary stones, urinary tract tumors, diabetes mellitus, and bleeding tendency. Eligible patients were randomly assigned to BTX-A group and placebo control group in a ratio of 2∶1. Two groups of patients received 20 intradetrusor injections of BTX-A 100U or placebo at the depth of the submucosal muscle layer respectively under cystoscope, including 5 injections at the base of the bladder, 3 injections to the bladder triangle, 5 injections each to the left and right walls and 2 injections to the top, sparing the bladder neck. As a placebo control group, patients received same volume of placebo containing no BTX-A and only adjuvant freeze-dried preparations for injection with the same method. A combination of gelatin, sucrose, and dextran served as adjuvants. Average micturition times per 24 hours, urinary incontinence (UI) episodes per day, average micturition volume per day, OAB symptom score(OABSS), and quality of life (QOL) score were recorded at baseline and the 2nd, 6th and 12th week after treatment. The primary efficacy endpoint was the change from baseline in the average micturition times per 24 hours at the 6th week after treatment. The secondary efficacy endpoints included the change from baseline in the average micturition times per 24 hours at 2nd and 12th week, as well as the change from baseline in the OABSS, QOL score, average frequency of urgency and UI episodes per day, urgency score, average micturition volume per day at 2nd, 6th and 12th week after treatment. Patients were followed for 12 weeks to assess adverse events (AEs). After assessed at week 12, if the micturition times has decreased less than 50% compared to baseline and the patient is willing to receive retreatment, then patients could enter the extended trial phase. In that phase, patients in both groups were injected with 100 units BTX-A from 12th week onwards and then followed up the same indicators for 12 weeks.Results:216 patients were enrolled in this trial (144 cases in the BTX-A group and 72 cases in the placebo control group). Baseline characteristics such as age (47.75±14.20 in the BTX-A group and 46.39±15.55 in the control group), sex (25 male/117 female in the BTX-A group and 10/61 in the control group), and disease duration (0.51 years in the BTX-A group and 0.60 years in the control group) were balanced between the two groups( P>0.05). A marked reduction from baseline in average micturition times per 24 hours was observed in all treatment groups at the 6th week and the reduction of the two groups was statistically different ( P<0.001 and P=0.008 respectively). Compared with the baseline, the average micturition times per 24 hours at the 6th week decreased from baseline by 2.40(0.70, 4.60)times for the BTX-A group and 0.70(-1.00, 3.30) times for the placebo control group respectively, and the difference between the two groups was considered to be statistically significant ( P=0.003). The change rates of average micturition times per 24 hours from baseline at the 6th week of the two groups were (16±22)% and (8±25)% respectively, and the difference between the two groups was statistically significant ( P=0.014). Compared with the baseline, the average micturition times per 24 hours at 2nd and 12th week decreased by 2.00(0.00, 4.00)and 3.30(0.60, 5.03)for the BTX-A group, 1.00(-1.00, 3.00)and 1.70(-1.45, 3.85)for the placebo control group respectively. The difference between two groups was considered to be statistically significant ( P=0.038 and P=0.012); the changes of average urgency times per day for the BTX-A group and the control group at the 2nd, 6th and 12th week were 2.00(0.00, 4.30)and 2.40(0.30, 5.00), 3.00(0.30, 5.70)and 0.70(-1.30, 2.70), 0.70(-1.30, 3.00) and 1.35(-1.15, 3.50), respectively. There were significant differences between two groups at the 2nd, 6th and 12th week, ( P=0.010, P=0.003 and P=0.025, respectively). The OABSS of the BTX-A group and the control group at the 6th week decreased by 1.00(0.00, 4.00)and 0.50(-1.00, 2.00) compared with the baseline, and the difference between the two groups was statistically significant ( P=0.003). 47 cases of BTX-A group and 34 cases of placebo control group entered the extended trial phase, and 40 and 28 cases completed the extended trial phase, respectively. The average micturition volume per 24 hours changed by -16.60(-41.60, -0.60)ml and -6.40(-22.40, 13.30)ml, (-35.67±54.41)ml and(-1.76±48.69)ml, (-36.14±41.51)ml and (-9.28±44.59)ml, (-35.85±43.35)ml and(-10.41±40.29)ml for two groups at the 12th, 14th, 18th and 24th week, and the difference between two groups was statistically significant at each follow-up time ( P=0.01, 0.006, 0.012 and 0.016, respectively). There was no significant difference in other parameters( P>0.05). However, adverse reactions after intradetrusor injection included increased residual urine volume (27 in the BTX-A group and 3 in the control group), dysuria (21 in the BTX-A group and 6 in the control group), urinary infection (19 in the BTX-A group and 6 in the control group), bladder neck obstruction (3 in the BTX-A group and 0 in the control group), hematuria (3 in the BTX-A group and 1 in the control group), elevated alanine aminotransferase (3 in the BTX-A group and 0 in the control group), etc. During the follow-up period, there was no significant difference in the other adverse events between two groups except the increase of residual urine volume( P<0.05). In the primary trial phase, among the 27 cases with increased residual urine volume in BTA group, only 1 case (3.70%) with PVR more than 300 ml; the PVR of 3 patients in the placebo group was less than 100 ml. The increase of residual urine volume caused by the injection could be improved or disappeared with the passage of time. Conclusions:Intradetrusor injection of Chinese BTX-A improved the average micturition times per 24 hours, the average daily urgent micturition times, OABSS, and average micturition volume per time, and reduced the adverse effects in patients with overactive bladder.Chinese BTX-A at dose of 100U demonstrated durable efficacy and safety in the management of overactive bladder.

Meigs' syndrome (MS), a rare complication of benign ovarian tumors, is easily misdiagnosed as ovarian cancer (OC). We retrospectively reviewed the clinical laboratory data of patients diagnosed with MS from 2009 to 2018. Serum carbohydrate antigen 125 and HE4 levels were higher in the MS group than in the ovarian thecoma-fibroma (OTF) and healthy control groups (all P < 0.05). However, the serum HE4 levels were lower in the MS group than in the OC group (P < 0.001). A routine blood test showed that the absolute counts and percentages of lymphocytes were significantly lower in the MS group than in the OTF and control groups (all P < 0.05). However, these variables were higher in the MS group than in the OC group (both P < 0.05). The neutrophil-to-lymphocyte ratio (NLR) was also significantly lower, whereas the lymphocyte-to-monocyte ratio was higher in the MS group than in the OC group (both P < 0.05). The NLR, platelet-to-lymphocyte ratio, and systemic immune index were significantly higher in the MS group than in the OTF and control groups (all P < 0.05). The hypoxia-inducible factor-1 mRNA levels were also significantly higher, whereas the glucose transporter 1, lactate dehydrogenase, and enolase 1 mRNA levels were lower in peripheral CD4
