RESUMO
This study aims to explore the molecular mechanisms of miR-206-3p in regulating Hsp90aa1 and its involvement in the central nervous system (CNS) injury in heat stroke. Weighted gene co-expression network analysis (WGCNA) was performed on the GSE64778 dataset of heat stroke to identify module genes most closely associated with disease characteristics. Through the selection of key genes and predicting upstream miRNAs using RNAInter and miRWalk databases, the regulatory relationship between miR-206-3p and Hsp90aa1 was determined. Through in vitro experiments, various methods, including bioinformatics analysis, dual-luciferase reporter gene assay, RIP experiment, and RNA pull-down experiment, were utilized to validate this regulatory relationship. Furthermore, functional experiments, including CCK-8 assay to test neuron cell viability and flow cytometry to assess neuron apoptosis levels, confirmed the role of miR-206-3p. Transmission electron microscopy, real-time quantitative PCR, DCFH-DA staining, and ATP assay were employed to verify neuronal mitochondrial damage. Heat stroke rat models were constructed, and mNSS scoring and cresyl violet staining were utilized to assess neural functional impairment. Biochemical experiments were conducted to evaluate inflammation, brain water content, and histopathological changes in brain tissue using H&E staining. TUNEL staining was applied to detect neuronal apoptosis in brain tissue. RT-qPCR and Western blot were performed to measure gene and protein expression levels, further validating the regulatory relationship in vivo. Bioinformatics analysis indicated that miR-206-3p regulation of Hsp90aa1 may be involved in CNS injury in heat stroke. In vivo, animal experiments demonstrated that miR-206-3p and Hsp90aa1 co-localized in neurons of the rat hippocampal CA3 region, and with prolonged heat stress, the expression of miR-206-3p gradually increased while the expression of Hsp90aa1 gradually decreased. Further in vitro cellular mechanism validation and functional experiments confirmed that miR-206-3p could inhibit neuronal cell viability and promote apoptosis and mitochondrial damage by targeting Hsp90aa1. In vivo, experiments confirmed that miR-206-3p promotes CNS injury in heat stroke. This study revealed the regulatory relationship between miR-206-3p and Hsp90aa1, suggesting that miR-206-3p could regulate the expression of Hsp90aa1, inhibit neuronal cell viability, and promote apoptosis, thereby contributing to CNS injury in heat stroke.
RESUMO
ObjectiveTo evaluate the effect of virtual reality (VR) on cognitive function and quality of life in patients with Parkinson's disease. MethodsA systematic search of CBM, CNKI, Wanfang data, VIP, Cochrane Library, Web of Science, Embase, and PubMed was carried out to identify randomized control trials (RCT) about the effect of VR technology on patients with Parkinson's disease from inception to February 29th, 2024. The control group received routine cognitive training, balance training or physical therapy, and the experimental group received VR technology. The quality of articles was evaluated using the Cochrane Collaboration's 5.1.0 RCT risk assessment tool for bias. The meta-analysis was performed using Revman5.4. GRADE was used to evaluate the evidence quality of outcome indicators. ResultsA total of 13 literatures involving 426 patients were included. Allocation concealment and blind methods were not described in most literatures, and selective reporting of research results or other biases was unclear. VR technology could improve the Motreal Cognitive Assessment (MoCA) score (MD = 1.11, 95%CI 0.31 to 1.90, P = 0.006), Trail Making Test (TMT)-A score (MD = -6.25, 95%CI -11.71 to -0.78, P = 0.030) and depression scale score (SMD = -0.56, 95%CI -0.95 to 0.18, P = 0.004) of patients with Parkinson's disease; however, it did not improve TMT-B score (MD = -6.01, 95%CI -28.16 to 16.14, P = 0.590), Unified Parkinson's Disease Rating Scale (UPDRS)-Part II score (MD = -2.11, 95%CI -4.97 to 0.75, P = 0.150) and Parkinson's Disease Questionnaire (PDQ-39) score (MD = -0.92, 95%CI -4.03 to 2.19, P = 0.560). For quality of evidence, MoCA score, UPDRS-Part II score and PDQ-39 score were low, and depression score and TMT score were moderate. ConclusionVR technology can improve the cognitive function and depression of patients with Parkinson's disease; however, no significant improvement is found in activities of daily living and quality of life.
RESUMO
To investigate the effect of adipose-derived stem cells (ASCs) transplantation on radiation-induced lung injury (RILI), Sprague-Dawley rats were divided into phosphate-buffered saline (PBS) group, ASCs group, Radiation + PBS group, and Radiation + ASCs group. Radiation + PBS and Radiation + ASCs groups received single dose of 30 Gy X-ray radiation to the right chest. The Radiation + PBS group received 1 mL PBS suspension and Radiation + ASCs group received 1 mL PBS suspension containing 1 × 107 CM-Dil-labeled ASCs. The right lung tissue was collected on Days 30, 90, and 180 after radiation. Hematoxylin-eosin and Masson staining were performed to observe the pathological changes and collagen fiber content in the lung tissue. Immunohistochemistry (IHC) and western blot (WB) were used to detect levels of fibrotic markers collagen I (Collal), fibronectin (FN), as well as transforming growth factor-ß1 (TGF-ß1), p-Smad 3, and Smad 3. Compared with the non-radiation groups, the radiation groups showed lymphocyte infiltration on Day 30 after irradiation and thickened incomplete alveolar walls, collagen deposition, and fibroplasia on Days 90 and 180. ASCs relieved these changes on Day 180 (Masson staining, P = 0.0022). Compared with Radiation + PBS group, on Day 180 after irradiation, the Radiation + ASCs group showed that ASCs could significantly decrease the expressions of fibrosis markers Collal (IHC: P = 0.0022; WB: P = 0.0087) and FN (IHC: P = 0.0152; WB: P = 0.026) and inhibit the expressions of TGF-ß1 (IHC: P = 0.026; WB: P = 0.0152) and p-Smad 3 (IHC: P = 0.0043; WB: P = 0.0087) in radiation-induced injured lung tissue. These indicated that ASCs could relieve RILI by inhibiting TGF-ß1/Smad 3 signaling pathway.
RESUMO
A UPLC-Q-Orbitrap-MS based metabolomic approach combined with biochemical assay and histopathological inspection were employed to study the intervention effects of Suanzaoren Decoction (SZRD) on chronic unpredictable mild stress (CUMS) depression rats, and to clarify the metabolic regulation pathway of SZRD. The rats were randomly divided into normal control group, CUMS model group, positive drug venlafaxine group, SZRD high (24 g·kg-1) and low (12 g·kg-1) dose groups, respectively. The CUMS model was replicated by subjecting to a variety of stimulus, such as thermal stimulation, ice water swimming, ultrasonic stimulation, tail clamping, day and night reversal, plantar electric shock and so on for rats. After oral administration of drugs for 28 days, the behavioral indexes of rats in each group were observed and the hippocampus and serum samples of rats were collected for biochemical assay and histopathological inspection. Compared with the CUMS model group, low dose and high dose SZRD groups can significantly reduce the immobility time of forced swimming (P < 0.001, P < 0.001), increase the sucrose preference rate (P < 0.01, P < 0.05), the number of crossings (P < 0.05, P < 0.01) and the number of uprights (P < 0.05, P < 0.01) in the open field test, suggesting that SZRD can significantly improve the depression-like behavior of CUMS model rats. In addition, SZRD could significantly reduce the levels of serum IL-6, IL-1β and TNF-α of CUMS model rats. A total of 21 differential metabolites in serum were identified by comparison with the data from the literature and databases. In addition, low-dose SZRD and high-dose SZRD improved the 8 and 11 perturbed potential serum biomarkers that were induced by CUMS, respectively, which related to alanine, aspartic acid and glutamic acid, tryptophan and arachidonic acid metabolism. This study provides a scientific basis for expanding the clinical indications of SZRD. This experiment was approved by the Animal Ethics Committee of Shanxi University (Approval No. SXULL2020028).
RESUMO
Objective To investigate the bacteriostatic activity of five hemostatic dressings for war injury to provide references for the development of novel hemostatic dressings.Methods The bacteriostatic ratios of Combat Gauze made of kaolin and four kinds of dressings made of chitosan including Celox Rapid Gauze,Celox Gauze,ChitoGauze and a self-developed dressing against S.aureus and E.coli were explored according to GB/T 20944.2-2007.The bacteriostatic time and activity were inferred by investigating the growth of S.aureus under simulated conditions.Results Combat Gauze had the hemostatic ratios lower than 20％against both S.aureus and E.coli within 24 h.The hemostatic ratios of Celox Rapid Gauze,Celox Gauze,ChitoGauze and the self-developed dressing against S.aureus were all higher than 90％after 30 min action,while the ratios of the four dressings against E.coli were slightly different and changed with the prolongation of the time of action:after 30 min action only Celox Rapid Gauze had the hemostatic ratio higher than 90％;after 3 h action,ChitoGauze had a low ratio of 35％while the other dressings were all higher than 95％;after 24 h action the four dressings all had the ratios higher than 99％.Celox Rapid Gauze,Celox Gauze,ChitoGauze and the self-developed dressing all significantly inhibited the growth of S.aureus within 15 h and the time for S.aureus to reach the threshold of clinical infection under simulated conditions was 18,15,24 and 15 h,respectively.Conclusion Combat Gauze is not effective in inhibiting S.aureus and E.coli,while Celox Rapid Gauze,Celox Gauze,ChitoGauze and the self-developed dressing behave well with Celox Rapid Gauze gaining high compre-hensive bacteriostatic activity and ChitoGauze having the longest bacteriostatic time against S.aureus.
RESUMO
Objective:To examine whether multiple-course prophylactic intravesical instillation chemotherapy is superior to single-course chemotherapy in preventing bladder tumor recurrence after radical nephroureterectomy(RNU)for primary upper tract urothelial carcinoma(UTUC).Methods:A comprehensive literature search was performed using the PubMed, Wanfang Data and China National Knowledge Infrastructure and all publications before March 2021 about clinical trials comparing the effects of single-course and multiple-course prophylactic intravesical instillation chemotherapy after RNU for UTUC were retrieved.Analysis was performed using Stata/SE 12.0.Results:Seven trials included a total of 998 patients, with 473 participants receiving multiple-course and 525 receiving single-course intravesical instillation chemotherapy.Bladder cancer recurrence occurred in 69 out of 473 patients(14.6%)with multiple-course chemotherapy and in 123 out of 525 patients(23.4%)with single-course chemotherapy.The absolute risk reduction was 8.8% and the relative risk reduction was 37.6%.Compared with a single-course instillation, the pooled OR of bladder cancer recurrence was 0.55(95% CI: 0.40-0.76, P<0.001)for multiple-course instillations.No serious adverse events were reported. Conclusions:Compared with single-course instillation chemotherapy, multiple-course prophylactic intravesical instillation chemotherapy significantly decreases the risk of bladder cancer recurrence in primary UTUC patients treated with RNU, indicating multiple intravesical instillation chemotherapy is superior to single instillation chemotherapy.

RESUMO
The aim is to study the tissue distribution characteristics of eight effective components in normal rats after oral administration of Ziziphi Spinosae Semen (ZSS) aqueous extract. An ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) analysis method was developed and validated for the determination of four flavonoids and four saponins in rat tissue using puerarin and ginsenoside Re as the internal standard (IS), respectively. Tissue samples including the heart, liver, spleen, lung, kidney, muscle, brain, small intestine, and serum, were collected from each rat at 0.5 h, 1.0 h, and 2.0 h after oral administration of ZSS aqueous extract (15 g·kg-1). All calibration curves exhibited good linearity (r > 0.994 6) over a wide concentration range for all components. The intra-day and inter-day precisions (RSD) at four different levels were both less than 19.77%, and the accuracies (RE) ranged from -19.68% to 19.46%; The extraction recoveries of the eight components ranged from 86.70% to 114.29%, and the matrix effects were from 82.14% to 114.57%. The validated method was successfully applied to the tissue distribution study of the eight components. The levels of swertisin, spinosin, 6‴-feruloylspinosin, and kaempferol-3-O-rutinoside in the small intestine were highest, then followed by the kidney, heart, and liver. Meanwhile, the levels of jujuboside A (JuA), jujuboside B (JuB), and jujuboside A1 (JuA1) in the small intestine were highest, then followed by the lung, spleen, and kidney. The concentrations of betulinic acid in the small intestine were higher than heart, lung, kidney, and liver. The flavonoids and saponins of ZSS with extremely low content could pass through the blood-brain barrier. The research results will provide an experimental basis for explaining the mechanism of nourishing the heart and tranquilizing the mind of ZSS. The animal experimental operations involved in this study followed the regulations of the Animal Ethics Committee of Shanxi University of Chinese Medicine and passed the animal experimental ethical review (No. 2021DW172).
RESUMO
Objective:To explore the efficacy and safety of robot assisted laparoscopic sacrocolpopexy in the treatment of pelvic organ prolapse.Methods:The data of 16 patients who underwent robot assisted laparoscopic sacrocolpopexy in Beijing Hospital from September 2019 to May 2022 were collected. The average age was (73.5±9.3) years, the preoperative course was 4-240 months, the body mass index was (24.2±1.7) kg/m 2, the number of births was (1.7±0.8), and the quantitative index of pelvic organ prolapse (POP-Q) was grade Ⅲ -Ⅳ. The maximum urine flow rate before operation was (9.6±3.4) ml/s, the maximum detrusor pressure during urination was 26 (20, 32) cmH 2O, the first sense urine volume of the bladder was (119.1±39.4) ml, the first sense urine urgency volume of the bladder was (253.6±75.7) ml, the maximum bladder pressure capacity was (406.0±79.8) ml, and the residual urine volume was 10 (10, 28) ml. The preoperative PFDI-20 score was 100 (70, 122) and the PFIQ-7 score was 107 (90, 160). During the robot assisted laparoscopic sacrocolpopexy, the right area of the sacral promontory was exposed, the anterior and posterior walls of the uterus were separated, and the 2 cm small hole was separated from the right broad ligament of the uterus. The mesh was cut into a "Y" shape and passed through the small hole. The anterior and posterior leaves of the Y-shaped mesh were sutured to fix the cervix, and the other end was fixed to the anterior longitudinal ligament of the sacrum. The operation time and intraoperative bleeding were observed. The effect of surgery was evaluated by preoperative and postoperative urodynamic imaging, POP-Q stage, PFDI-20 score and PFIQ -7 score. Results:All the 16 operations were successfully completed. No injury of urethra, bladder, rectum, important blood vessels and nerves occurred during the operation. The average operation time was (255.6±56.0) min, and the average amount of bleeding was (28.8±18.2) ml. There was no inhibitory contraction wave in 7 patients (44%) before operation, suggesting that there was detrusor overactivity. After operation, the detrusor overactivity disappeared or significantly decreased in 7 patients. The postoperative follow-up period was 3-36 months. During the follow-up period, one patient had recurrence, and the rest had no prolapse and urination problems. The POP-Q stage was reduced to grade 0-Ⅰ after the operation. The subjective satisfaction rate of patients was 94%. The PFDI-20 score [13(8, 24)] and PFIQ -7 score [11(6, 15)] after operation were significantly reduced ( P<0.001), the initial urgent volume of bladder (272.5±88.5) ml was significantly increased compared with that before operation ( P=0.038), and the maximum volume of bladder (427.2±79.2) ml was significantly increased compared with that before operation ( P=0.006). Image urodynamics showed that the patient basically recovered the pelvic floor anatomy and achieved functional reduction. Conclusions:Robot assisted laparoscopic sacrocolpopexy has good subjective and objective effects in POP, low recurrence rate and less complications. It needs a larger sample size study for confirming the improvement of bladder function.
RESUMO
Objective: To investigate the diagnostic efficiency and incremental value of quantitative myocardial blood flow measurements by Cadmium-Zine-Telluride (CZT) single photon emission computed tomography (SPECT) dynamic myocardial perfusion imaging (MPI) in patients with coronary artery disease (CAD) compared with traditional semi-quantitative measurements by MPI. Methods: This is a retrospective, cross-sectional study. We retrospectively analyzed clinical data of patients with suspected or known CAD, who underwent the dynamic MPI quantitative blood flow measurement of CZT SPECT in TEDA International Cardiovascular Hospital from October 2018 to December 2020. Clinical data, semi-quantitative parameters (stress score (SS), rest score (RS) and different score (DS)) and myocardial quantitative blood flow parameters (rest myocardial blood flow (rMBF), stress myocardial blood flow (sMBF) and myocardial flow reserve (MFR)) were analyzed. According to the results of coronary angiography, patients were divided into the stenosis group and the control group with coronary artery stenosis ≥50% or ≥75% as the diagnosis criteria. The differences of quantitative and semi-quantitative parameters between the two groups were compared, and the diagnostic efficacy was compared by receiver operating characteristic(ROC) curve. Results: A total of 98 patients with a mean age of (62.1±8.7) years were included in the study, including 66 males (67%). At the patient level, with the positive standard of coronary artery stenosis≥50%, the left ventricle (LV) stress MBF (LV-sMBF) ((1.36±0.45) ml·min-1·g-1) and LV-MFR (1.45±0.43) of the stenosis group were lower than the LV-sMBF ((2.09±0.64) ml·min-1·g-1) and LV-MFR (2.17±0.54) of control group; summed SS and summed DS were higher than control group (all P<0.05). With the positive standard of coronary artery stenosis ≥75%, the LV-sMBF ((1.19±0.34) ml·min-1·g-1) and LV-MFR (1.34±0.35) of stenosis group were lower than the LV-sMBF ((1.94±0.63) ml·min-1·g-1) and MFR (2.00±0.58) of control group; all semi-quantitative parameters were higher than control group (all P<0.05). At the vascular level, with coronary artery stenosis ≥50% as the diagnosis criteria, the sMBF ((1.26±0.49) ml·min-1·g-1) and MFR (1.35±0.46) of stenosis group were lower than the sMBF ((1.95±0.70) ml·min-1·g-1) and MFR (2.05±0.65) of control group; SS and DS were higher than control group (all P<0.05). With coronary artery stenosis≥75% as the diagnosis criteria, the sMBF ((1.12±0.41) ml·min-1·g-1) and MFR (1.25±0.38) of stenosis group were lower than the sMBF ((1.84±0.70) ml·min-1·g-1) and MFR (1.93±0.66) of control group; all semi-quantitative parameters were higher than control group (all P<0.05). With coronary artery stenosis≥50% as the diagnosis criteria and CAG as the reference standard, the AUC and 95%CI of myocardial quantitative blood flow parameters indicated by ROC curve for diagnosis of CAD were 0.830 (0.783-0.877). The sensitivity (86.1% vs. 61.5%), specificity (82.6% vs. 73.8%), positive predictive value (77.8% vs. 62.5%), negative predictive value (89.3% vs. 73.0%) and accuracy (84.0% vs. 68.7%) were all higher than the semi-quantitative parameters (all P<0.05). With coronary artery stenosis≥75% as the diagnosis criteria, the AUC and 95%CI of myocardial quantitative blood flow parameters indicated by ROC curve for diagnosis of CAD were 0.832(0.785-0.879). The sensitivity (89.2% vs. 67.6%), negative predictive value (95.5% vs. 86.2%) and accuracy (80.6% vs. 68.0%) were all higher than semi-quantitative parameters (all P<0.05). Conclusion: Compared with traditional SPECT MPI derived semi-quantitative parameters, diagnostic efficacy for CAD is higher using CZT SPECT quantitative myocardial blood flow parameters, this strategy thus has additional diagnostic benefits and incremental value on the diagnosis of CAD.

Objective: To compare and analyze the perioperative clinical effects of minimally invasive Ivor-Lewis esophagectomy (MIE-Ivor-Lewis) and minimally invasive McKeown esophagectomy (MIE-McKeown). Methods: A total of 147 patients who underwent endoscopic esophageal cancer surgery from April 2018 to August 2019 were selected, including 85 patients undergoing MIE-McKeown surgery and 62 patients undergoing MIE-Ivor-Lewis surgery. The measurement data were expressed as (x±s), the comparison of normally distributed measurement data was performed by independent sample t-test, and the comparison of count data was performed by χ(2) test or Fisher's exact test. Results: The operation time of McKeown (M) group and Ivor-Lewis (IL) group were (219.2±72.4) minutes and (225.8±65.3) minutes. The mediastinal lymph node dissection number of M and IL groups were 13.3±4.8 and 11.6±6.5, respectively. The number of left recurrent laryngeal nerve lymph node dissection were 3.5±1.2 and 3.1±1.4, respectively. The intraoperative blood loss were (178.3±41.3) ml and (163.2±64.1) ml, respectively. The number of patients reoperated for postoperative bleeding were 1 and 0, respectively. The number of patients with postoperative gastric bleeding were 0 and 1, respectively. The postoperative chest tube retention time were (2.8±1.3) days and (3.1±1.2) days, respectively. The number of patients with anastomotic leakage were 7 and 1, respectively. The number of patients with lung infection were 13 and 5, respectively, and with chylothorax were 2 and 1, respectively, without statistically significant difference (P>0.05). The number of patients with hoarseness were 11 and 3, respectively. The total incidence of complication were 41.2% (35/85) and 17.7% (11/62), and the postoperative hospital stay were (14.7±6.5) days and (12.3±2.3) days, with statistical difference (P<0.05). Conclusion: MIE-Ivor-Lewis and MIE-McKeown are safe and effective in treating esophageal cancer, but the complication of MIE-Ivor-Lewis is less than that of MIE-Mckeown, and the perioperative clinical effect of MIE-Ivor-Lewis is better than that of MIE-McKeown.

Objective:To explore the potential relationship of urethral pressure profilometry and the complications of artificial urethral sphincter (AUS) implantation.Methods:The clinical data of patients who underwent AUS implantation in Beijing Hospital from March 2019 to March 2022 were retrospectively analyzed. All the patients were male. The average course of disease was 43.1 months(ranging 11-120 months). The average age was (68.6±13.2) years. The median number of pads used was 4.5 (3.0, 6.0). The preoperative maximum urethral pressure (MUP) was (84.6±25.5) cmH 2O, and the maximum urethral closure pressure (MUCP) was 51.0 (41.0, 74.0) cmH 2O. AUS implantation was performed through a single perineal incision in all patients. The sleeve size was mainly determined by the measured urethral circumference of the patient. After installation of all components, the urethral pressure profilometry was performed under the state of device inactivation and activation. The pump was activated 6 weeks after the operation, and telephone follow-up was performed 3 months after the activation of the device. The urinary control and complications were recorded. The results of follow-up were compared with the results of urethral pressure profilometry, and the preliminary conclusions were drawn. Results:In this study, 3 patients (20%) received 4.0cm cuffs, 10 patients (66.7%) received 4.5cm cuffs, and 2 patients (13.3%) received 5.0cm cuffs. The MUP and MUCP of AUS device in inactivated state were (82.5±30.2) cmH 2O and 51.0(48.0, 77.0) cmH 2O. In the activated state, MUP was (138.9±21.7) cmH 2O and MUCP was 109.0(94.0, 133.0) cmH 2O. Compared with that before operation, the urethral pressure in the inactivated state did not increase significantly (all P > 0.05), while the urethral pressure in the activated state increased significantly (all P < 0.001). The patients were followed-up for 3-33 months. Thirteen patients (86.7%) used the initial installation device, and all of them met the standard of social continence. One patient died of cerebrovascular accident. One patient took out the device due to urethral erosion. The incidence of complications was 26.7% (4/15), including painless hematuria in 2 cases, scrotum and penis infection in 1 case, and urethral erosion in 1 case. The MUP and MUCP of these patients were (100.0 ± 40.7) cmH 2O and (80.8 ± 39.7) cmH 2O respectively. In the intraoperative active state, the MUP was (151.5 ± 15.3) cmH 2O and the MUCP was (123.0 ± 17.2) cmH 2O. The MUP of the other 3 patients in the device activation state was significantly higher than the average value, and all of them were above 150 cm H 2O, except one patient who was infected due to cognitive problems and chronic urinary retention. In 11 patients without complications, the MUP and MUCP were (76.1±24.7) cmH 2O and (55.1±20.0) cmH 2O respectively. In the intraoperative active state, the MUP was (134.4±22.5) cmH 2O and the MUCP was (108.5±29.8) cmH 2O. Conclusions:AUS implantation has a definite curative effect. Poor comprehension, and MUP higher than 150 cmH 2O in the activated state of the device may be risk factors for complications.
RESUMO
BACKGROUND: The vulnerability of adolescents to emotional disorders such as stress, anxiety, anger, depression, and emotional breakdown is a matter of great concern and urgent need. Studies in several countries and regions have reported higher prevalence of depression, stress, and anxiety in adolescents. Several studies have shown that mindfulness-based interventions have an ameliorative effect on both emotional disorders and psychological problems in adolescents. The purpose of this study is to systematically analyze the effects of mindfulness-based intervention on emotional disorders and psychological problems in adolescents, and to provide a reasonable mindfulness-based intervention program for adolescents with emotional disorders. METHODS: Electronic databases including Google Scholar, EMBASE, Web of Science, PubMed, the CNKI, the Chinese Science and Technology Periodical Database, VIP, Wanfang, and Cochrane Library. These databases will be searched to identify randomized controlled trials (RCTs) published before October 2021. Only Chinese and English literature will be included. We will use the criteria provided in Cochrane Handbook 5.3.0 for quality assessment and risk assessment and Revman 5.3 software for meta-analysis. The primary outcome are mainly evaluated by PHCSS, SDS and SAS in adolescents. CONCLUSION: The results of this study may provide a strong basis for improving emotional disorders and psychological problems in adolescents.Systematic review registration: INPLASY2021110054.

RESUMO
Objective:To investigate the expression of circhipk3 in microglial cells in heat-induced neurological injury, and to preliminary analyze the effect of circhipk3 on microglial polarization in heat-induced neurological injury.Methods:Mice were randomly (random number) divided into a control group and a heat radiation disease 0.8 h group (HS 0.8), a heat radiation disease 8h group (HS 8), and a heat radiation disease 24 h group (HS 24). By establishing a mouse model of heat shock (HS), heat-damaged brain tissue was obtained, microglia were isolated and RNA was extracted. Quantitative PCR method was used to detect M1 and M2 marker molecules in microglia, and to evaluate the polarization direction and type of microglia. The expression level of circhipk3 was detected in microglial cells in heat-induced neurological injury, and the effect of circhipk3 on microglial polarization was further elucidated by intervening the expression of circhipk3 in microglial cells.Results:The expression of CD45 and CD11-b in the HS 8 group was significantly higher than that in the control group [(4.41±0.18) vs. (1±0.15), P=0.000], [(3.47±0.19) vs (1±0.15), P=0.000] , and the CD45 and CD11-b of the HS 24 group was significantly lower than that of the HS 8 group [(1.34±0.15) vs. (4.41±0.18), P=0.000], [(1.38±0.21) vs. (3.47±0.19), P= 0.001]. At the same time, the expression of CD206, FIZZ and Arg1 in the HS 8 group started to increase compared with the control group [(1.59±0.16) vs. (1±0.12), P=0.014], [(1.62±0.15) vs. (1±0.15), P=0.002 ], [(2.23±0.28) vs. (1±0.19), P=0.004], and CD206, FIZZ, and Arg1 in the HS 24 group were significantly higher than those in the control group [(2.67±0.20) vs. (1±0.12), P=0.002], [(2.19±0.15) vs. (1±0.15), P=0.000], [(3.04±0.18) vs. (1±0.19), P=0.001]; circhipk3 mimicis significantly increased the expression of Arg1 [(7.26± 0.06) vs. (3.86±0.06), P=0.000]; at the same time, circhipk3 inhibitor promoted the expression of CD45 and HO-1 [(2.96±0.03) vs. (1.63±0.09), P=0.000], [(2.52±0.10) vs. ( 1.30±0.02), P=0.000]. Conclusions:Microglial cells are predominantly M1-type in early neurological injury of heat radiation disease. HO-1 may be one of the microglial M1-type markers. The high expression of circhipk3 in microglial cells mainly promotes its transformation to M2 type.
RESUMO
Objective:To investigate the value of serum IL-23 in predicting the progression of prostate cancer at different stages of treatment.Methods:A total of 124 patients with metastatic prostate cancer diagnosed in Beijing Hospital from June 2018 to March 2019 were collected.Patients were TNM-staged according to the Prostate Cancer Guidelines of the European Association of Urology.Serum IL-23 levels were measured in patients with metastatic castration resistance prostate cancer(mCRPC), metastatic castration sensitive prostate cancer(mCSPC)and benign prostatic hyperplasia(BPH), respectively.Patients with mCRPC were subgrouped based on disease stability, and serum IL-23 levels were compared between the subgroups.Serum IL-23 levels in the groups were analyzed and compared with the Gleason score and the prostate-specific antigen(PSA)level.Results:The median value of serum IL-23 in the mCRPC group was 79.73(45.61, 95.63)μg/L, which was higher than that in the BPH group[30.88(15.01, 44.94)μg/L, Z=22.66, P=0.000]and the mCSPC group[46.10(35.27, 80.92)μg/L, Z=11.46, P=0.001]. Serum IL-23 levels were higher in the mCSPC group than in the BPH group( Z=7.17, P=0.007). Analysis for the subgroups showed that the median value of serum IL-23 was 110.25(88.47, 159.09)μg/L in mCRPC patients with unstable disease, which was higher than that in mCRPC patients with stable disease[46.52(44.97, 80.33)μg/L, Z=33.99, P=0.000]. There was no significant difference in serum IL-23 levels between mCRPC patients with stable disease and mCSPC patients[46.10(35.27, 80.92)μg/L]( Z=0.35, P=0.554). Conclusions:Serum IL-23 can be used as a potential biological indicator to predict the therapeutic effect of mCSPC and to predict tumor metastasis.
RESUMO
Objective:To investigate the clinical characteristics of elderly patients with coronavirus disease 2019(COVID-19), in order to provide scientific evidence for the diagnosis and treatment of COVID-19 in elderly patients.Methods:Clinical data of 102 patients with COVID-19 admitted to the B11 East Ward of the Zhongfaxincheng campus and the E1-3 ward of the Guanggu Campus of Tongji Hospital affiliated to Huazhong University of Science and Technology in Wuhan from 1 February 2020 to 28 February 2020 were retrospectively collected and analyzed.Patients were categorized into 2 groups: the elderly group(≥60 years old)and the young and middle-aged group(<60 years old). Differences in epidemiological features, demographics, clinical symptoms, laboratory results and imaging findings between the two groups were retrospectively analyzed.Results:Among 102 patients with COVID-19, 58 were in the elderly group(≥60 years old), with a median age of 67.0(63.8, 71.0)years old, and 44 in the young and middle-aged group(<60 years old), with a median age of 47.5(38.0, 51.8)years old.There was no significant difference in gender ratio between the two groups( χ2=0.033, P=0.855). Of 102 patients, 42.0%(21/50)had close contact with an infected person, 14.0%(7/50)were from infection clusters, and 18.0%(9/50)had suspected hospital-acquired infections.Fever and cough remained the most common symptoms, but gastrointestinal symptoms such as nausea, poor appetite, diarrhea and muscle cramps were also warning signs.Fatigue and cough were the most common presenting symptoms in elderly male patients.Bilateral patchy infiltrates(57.9%, 22/38)and ground-glass opacities(42.1%, 16/38)were the main imaging features and 42.1%(16/38)patients had multiple areas of the lungs involved.Over 50% patients had increased levels of blood glucose, D-dimer, fibrinogen, C-reactive protein, procalcitonin, multiple cytokines and neutrophil-to-lymphocyte ratio, as well as decreased levels of albumin, hemoglobin, hematocrit, lymphocytes and serum calcium.Compared with the young and middle-aged group, the elderly group had higher rates of abnormality in levels of D-dimer and serum calcium( χ2=7.067 and 4.166, P=0.008 and 0.041). Conclusions:Fever and cough are the most common symptoms in elderly patients with COVID-19.Elderly patients with COVID-19 have multiple abnormalities in clinical laboratory test results, which show a certain level of specificity compared with young and middle-aged patients.
RESUMO
Objective:To evaluate the efficacy and safety of robotic arm assisted laparoscopic hysterosacral fixation in patients with pelvic organ prolapse(POP), and its impact on lower urinary tract function.Methods:This study retrospectively analyzed the clinical data of POP patients who had undergone robotic arm assisted laparoscopic hysterosacral fixation at our center from June 2019 to October 2020, and conducted exploratory research.Results:A total of 6 patients were included in the study, with POP quantitative staging above stage Ⅲ.The ages ranged from 70 to 82 years.The number of births each patient had given ranged from 1 to 3, & all were via vaginal deliveries.There were no significant changes in urodynamic parameter scores in any patients before and after surgery, but half of the patients had detrusor overactivity before surgery, which all disappeared after surgery.In addition, synchronous X-ray images showed that the postoperative pelvic organs were closer to the normal anatomical position.At the same time, quantitative staging of POP had achieved clear improvement, and related scale scores also significantly improved.One patient complained of occasional lumbar and back discomfort with postoperative over-stretching during outpatient review, which improved after symptomatic treatment.Conclusions:robotic arm assisted Laparoscopic hysterosacral fixation is satisfactory in efficacy and safety for POP patients, with good postoperative restoration of the uterus to the anatomical position and has insignificant influence on the function of the lower urinary tract.It is worth further assessment for wide application.
RESUMO
In this paper we investigate cluster collective behaviors aroused by epidemic spread in a patchy population via feedback pinning control strategy. We construct a class of complex network system combined with states feedback behavior synchronization network systems and epidemic spread constant population systems with patch dispersal. In which the dispersal effect among patches are included in the susceptible systems, as well as considering the contact willing function for each patch, determined by the disease's information and individuals' behaviors, as the added cofactor before bilinear incidence. On the one hand, we derive conditions about the global asymptotical stability of disease-free equilibrium, and the existence of positive equilibrium. On the other hand, we design states feedback controllers related with the patch disease information to achieve cluster behaviors synchronization. By using the Lyapunov stability analysis method, the global asymptotical stability of the positive equilibrium is discussed, and meanwhile, the criteria for cluster collective behaviors are obtained. Numerical simulations are performed to support our theoretical results.

Many complex systems can be modeled as directed networks, which can be regarded as a generalization of undirected networks. In this paper, epidemic dynamics and immunization strategies in directed networks are studied. First, a Susceptible-Infected-Susceptible (SIS) model on a directed network is established employing the mean-field method, and its dynamics and epidemic threshold of the network are studied. Then based on the continuous degree technique, namely, considering the degree of a node as a continuous variable, we propose a method to calculate the epidemic threshold of the immunized network. Besides, some immunization strategies, including optimal immunization, random immunization, combined targeted immunization, and combined acquaintance immunization, and three special networks are considered. Finally, through numerical analysis, all immunization strategies are simulated and compared on different types of networks. We find that the nodes with the largest product of in-degree and out-degree are the most worthy of being immunized.
