Objective:To verify the clinical efficacy and safety of Qufeng Tongxuan method in treating low- and moderate-volume intracerebral hemorrhage at acute stage.Methods:A prospective, multicenter, randomized, double-blind, placebo-controlled study was performed; patients with low- and moderate-volume intracerebral hemorrhage at the basal ganglia and/or thalamus accepted treatment in 16 hospitals from September 2019 to April 2022 were enrolled. These patients were divided into experimental and control groups with a block randomized method by SAS software. Patients in control group were given conventional western medicine treatment; those in experimental group accepted Qufeng Tongxuan method (sequential therapy of Shexiang Huayu Xingnao granules and Zhilong Huoxue Tongyu granules) besides conventional western medicine treatment. NIHSS was used to assess neurological function before treatment and on 7 th, 14 th, 30 th, and 90 th d of treatment. Prognoses of these patients were assessed by modified Rankin scale (mRS) before treatment and on 180 th d of treatment. Brain CT was performed before treatment and on 7 th and 14 th d of treatment to calculate the hematoma volume. Before treatment and on 14 th d of treatment, changes of coagulation function, liver and kidney functions of the 2 groups were compared. Adverse reactions during treatment in the 2 groups were recorded. Results:No significant differences in NIHSS scores were noted between the 2 groups before treatment, on 7 th, 14 th, and 30 th d of treatment ( P>0.05); NIHSS scores in experimental group on 90 th d of treatment were signficantly lower than those in control group ( P<0.05); NIHSS scores in experimental group decreased gradually before treatment and on 7 th, 14 th, 30 th and 90 th d of treatment, with statistical significances ( P<0.05). No significant differences in mRS scores were noted between the 2 groups before treatment ( P>0.05); mRS scores in experimental group on 180 th d of treatment were signfciantly lower than those in control group ( P<0.05). No significant difference in hematoma volume was noted between the 2 groups before treatment and on 7 th and 14 th d of treatment ( P>0.05); both groups had gradually decreased hematoma volumes before treatment and on 7 th and 14 th d of treatment, respectively, with significant differences ( P<0.05); the volume difference of hematoma between 14 th d of treatment and before treatment in experimental group (6.42[4.10, 11.73]) was significantly higher than that in control group (4.00[1.25, 10.58], P<0.05). No significant differences in liver and kidney function indexes or coagulation function indexes were noted between the 2 groups before treatment and on 14 th d of treatment ( P>0.05). Adverse reaction incidence was 9.52% ( n=12) in experimental group and 10.34% ( n=12) in control group, without statistical difference ( P>0.05). Conclusion:Under premise of conventional western medicine treatment, Qufeng Tongxuan method can promote hematoma absorption and improve neurological deficit symptoms in low- and moderate-volume intracerebral hemorrhage at acute stage, without obvious adverse reactions.

Purpose: Over-activation of nuclear factor kappa B (NF-κB) was proven to be involved in the pathogenesis of preeclampsia. However, its regulation mechanism is not clear yet. This paper explored the role of WD repeat domain 5 (WDR5) in the development of late-onset preeclampsia and its relationship with NF-κB. Methods: WDR5 expression was detected in normal placentas and placentas from late-onset preeclampsia patients. CCK-8 and colony formation assays were conducted to appraise the proliferative ability of trophoblast. Migration and invasion were observed by wound healing and transwell assays. The interaction between WDR5 and NF-κB inhibitor I-kappa-B-alpha (IkBa) was verified by Co-immunoprecipitation analysis. Immunofluorescence was used to analyze the activation of NF-κB. Finally, we tested the role of WDR5 using the mice late-onset preeclampsia model. Results: WDR5 was highly expressed in the placentas of late-onset preeclampsia patients. WDR5 overexpression suppressed cell proliferation, migration, and invasion in trophoblast. WDR5 could interact with IkBa to activate NF-κB. Knockdown of NF-κB counteracted the anti-proliferative and anti-metastatic effects of WDR5 overexpression in trophoblast. In-vivo studies suggested that targeting WDR5 combated late-onset preeclampsia development. Conclusions: Our finding provides new insights into the role of WDR5 in late-onset preeclampsia development.

Astragaloside IV is a biologically active substance derived from the traditional Chinese medicine Astragalus mambranaceus Bunge, and has antioxidant, anti-inflammatory, and anti-apoptotic properties. In this study, we aimed to investigate the effects of astragaloside IV on Klebsiella pneumonia rats and the underlying mechanisms. Klebsiella pneumoniae (K. pneumoniae) rats were treated with different dosages of astragaloside IV (5, 10, and 20 mg/kg) by intragastric administration. The levels of pro-inflammatory cytokines interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α in bronchoalveolar lavage fluid (BALF) were determined. Pathological changes of lung tissue were inspected by HE staining. The expression of transforming growth factor (TGF)-β1 in lung tissue was determined with immunohistochemistry, and the expression levels of TGF-β1, p-Smad2/Smad2, p-Smad3/Smad3, IκBα/p-IκBα, and p65/p-p65 in lung tissue were determined by western blot. The mechanism was further investigated with TGF-β1 inhibitor SB-431542. Astragaloside IV reduced the elevated levels of pro-inflammatory cytokines caused by K. pneumoniae and improved lung tissue damage in a dose-dependent manner. Astragaloside IV also decreased the expression of TGF-β1/Smad signaling pathway-related proteins and decreased the protein levels of inflammation-related p-IκBα and p65 in lung tissues induced by K. pneumoniae. Additionally, it was found that the effects of 20 mg/kg astragaloside IV were similar to SB-431542, which could improve pulmonary fibrosis induced by K. pneumoniae, decrease the levels of TGF-β1/Smad signaling pathway-related proteins in lung, and reduce inflammation at the same time. Astragaloside IV could alleviate the inflammation of rat pneumonia induced by K. pneumoniae through suppressing the TGF-β1/Smad pathway.

ABSTRACT Introduction The maximal oxygen consumption rate (VO2max) can directly reflect the body's aerobic metabolism and oxygen delivery system. This is a measure of aerobic capacity used to monitor swimmers' levels and their strength and speed performance. Objective Verify the changes in VO2max when incorporating aerobic exercise training into swimmers' regular training. Methods 12 volunteer swimmers were divided into two categories: strength training group and regular training group. Both groups performed a fitness test on the 200-meter track before starting the training. VO2 maximal was measured and worked out statistically to verify the results of this competition. The effects of aerobic exercise on the strength and competitive status of the athletes were investigated according to an updated literature review. Results There was a significant change in the maximal oxygen uptake of the athletes after the experimental protocol. The athletes in the strength training group increased their VO2 max compared to the regular training group. The results showed a significant difference in the VO2max index before and after strength training (P<0.05). This suggests that strength training has a significant effect on maximal oxygen consumption. Conclusion Strength training interventions significantly affect athletes' maximal oxygen consumption intensity and exercise capacity. The aerobic exercise intervention showed evidence of improving the competitive level of athletes. Level of evidence II; Therapeutic studies -investigation of treatment outcomes.

@#BACKGROUND: Spontaneous isolated superior mesenteric artery (SMA) dissection (SISMAD) is a rare cause of abdominal pain. The aim of the study is to investigate the role of a new parameter, the ratio of the SMA diameter to the superior mesenteric vein (SMV) diameter (SMA/SMV) based on non-enhanced computed tomography (CT), in the early diagnosis of SISMAD. METHODS: In a registry study from December 2013 to June 2021, 97 abdominal pain SISMAD patients (SISMAD group) admitted to our hospital were enrolled. Meanwhile, the matched sex and age abdominal pain non-SISMAD patients at 1:2 were collected in reverse chronological order as the control group. Student's t-test, Wilcoxon rank-sum test, and Chi-square test were used to compare differences between the SISMAD and control groups. MedCalc was used to generate receiver operating characteristic (ROC) curve. RESULTS: A total of 291 abdominal pain patients, including 97 SISMAD patients and 194 non-SISMAD patients, were included in the current study. The maximum SMA diameter, perivascular exudation, and SMA/SMV based on non-enhanced CT were significant between the two groups (all P<0.05). ROC curves showed that for the maximum SMA diameter, the area under the curve (AUC), cut-off, sensitivity, and specificity were 0.926, 9.80, 93.8%, and 79.4%, respectively. For SMA/SMV, its AUC, cut-off, sensitivity, and specificity were 0.956, 0.83, 88.7%, and 92.3%, respectively. The diagnostic efficiency of SMA/SMV was better than that of the maximum SMA diameter (P<0.05). The combined parameters of SMA/SMV and maximum SMA diameter had the best diagnostic efficiency (AUC=0.970). CONCLUSION: SMA/SMV may be a potential marker for SISMAD.

OBJECTIVE@#To investigate the method and clinical effects of the treatment of recurrent anterior dislocation of shoulder with Hill-Sachs injury by arthroscopic Bankart repair and Remplissage.@*METHODS@#From March 2016 to March 2019, 106 patients with recurrent anterior dislocation of shoulder with glenoid bone defect less than 20% underwent arthroscopic Bankart repair, including 76 males and 30 females, aged from 18 to 45 (27.3±8.6) years, 59 cases of left shoulder and 47 cases of right shoulder. Range of motion (ROM), American Shoulder and Elbow Surgeons(ASES) score, Constant-Murley score and Rowe score were used to evaluate shoulder functionand stability before and after operation.@*RESULTS@#All patients were followed up, and the duration ranged from 21 to 60 months, with a mean of (41.5± 8.5) months. One patient developed infection after operation, and the infection was controlled after arthroscopic debridement again. The remaining patients did not have clinical complications such as infection, intra articular hematocele and redislocation. Shoulder flexion and lifting increased from (158.33±15.72) ° preoperatively to (169.43±10.04) ° at the latest follow up, and internal rotation changed from T7 (T4 to T10) preoperatively to T8 (T5 to T10) at the latest follow up;the average lateral external rotation and abduction 90 ° external rotation decreased from (58.46±15.51) ° preoperatively and (99.37±14.09) ° to (53.18±14.90) ° and (92.52±13.10) ° at the latest follow up, respectively. The ASES score, Constant -Murley score and Rowe score were significantly improved.@*CONCLUSION@#The clinical effect of rehabilitation of Bankart repair combined with Remplissageunder arthroscopy in the treatment of recurrent dislocation of shoulder joint in adults with Hill-Sachs defect is satisfactory. Although the external rotation function is weaker than that before operation, it can effectively reconstruct the shoulder function and avoid the occurrence ofdislocation after operation.

Objective @#To explore the feasibility of antler powder/silk fibroin/polyvinyl alcohol scaffolds as tissue engineering bone scaffolds and the relationship between their degradation performance and the healing speed of bone defects.@*Methods @# Antler powder/silk fibroin/polyvinyl alcohol scaffolds and nano hydroxyapatite/silk fibroin/polyvinyl alcohol scaffolds were prepared by 3D printing. The whole bone marrow culture method was used to prepare blood cell sheets of Altay big tail sheep’s iliac bone marrow. With observation times of 1, 2 and 3 months, the mandibular defects of 4 sheep were established. The experimental group was coated with antler powder/silk fibroin/polyvinyl alcohol scaffolds. The control group was coated with nanohydroxyapatite/silk fibroin/polyvinyl alcohol scaffolds. The negative control group was coated with gel-free sponges. According to the self-control method of the bilateral mandible defect area, scaffolds wrapped with cell membranes or gel sponges wrapped with cell membranes were implanted. At the ends of the first, second and third months after implantation, the experimental animals were killed, cone beam CT was performed, and paraffin sections were taken for HE staining to evaluate the effect of different scaffold materials on bone regeneration and scaffold degradation.@* Results@# Scanning electron microscopy showed that both groups had regular pores and good continuity, and there was no difference in pore size and porosity between the two groups (P > 0.05). The results of CBCT imaging showed that in 3 months after operation, the experimental group had significantly better repair effects on bone defects than the control group, and the degradation rate matched the bone repair rate. The bone mineral density in the center of the defect was higher than that of the control group, which was close to that of normal bone tissue. The central bone mineral density of the experimental group at each time point was higher than those of the control group and the negative control group, and the difference was statistically significant (P < 0.05). HE staining results showed that the bone cells in the experimental group were more active, with more new capillaries and bone trabeculae formed, and the scaffold material absorbed more than the control group. @*Conclusion @#The antler powder/silk fibroin/polyvinyl alcohol scaffold can promote the repair of critical bone defects. Its degradability matches its bone tissue healing rate. It is expected to become a promising scaffold material for bone tissue engineering.

Methods:From January to June 2019, 40 cases of left-behind children with confirmed VAD <1 year old were enrolled in Zunyi area as VAD group, and 40 healthy children were selected as healthy control group.Urine from the 2 groups of children was collected and 1H-NMR spectrum was measured.By combining metabonomics technology and multivariate statistical analysis, the 2 groups of metabolites were compared, and the differential metabolites of children with VAD were screened out. Results:Compared with VAD group [(0.56±0.10)μmol/L], the difference in the serum retinol concentration of healthy control group [(1.35±0.18)μmol/L] was statistically significant ( t=23.93, P<0.001). Compared with healthy group, VAD group showed higher level of methylmalonate, 2-ketoisovalerat, N-acetyl glycoprotein signal, dimethylglycine and betaine, with statistically significant differences (| r|>0.602, all P<0.05). The level of Isovalerylglycine, 2-hydroxyisobutyrate, creatine, phosphate choline/glycerophosphocholine, 4-PY and Hippurate were significantly decreased, with statistically significant differences (| r|>0.602, all P<0.05). Conclusions:Compared with healthy children, children with VAD have differences in urine Metabolites.Differential metabolites are closely correlated with intestinal microecological ba-lance, digestive system diseases, respiratory system diseases, immune-related diseases, energy metabolism, growth and development.Urine 1H-NMR metabolomics analysis has potential application value in the early screening of VAD.

ABSTRACT: Based on the data of "employment and food demand of urban migrant workers", this paper empirically analyzed the impact of urban pension insurance on the nutritional intake structure of migrant workers. The results showed that participating in urban pension insurance can change the nutritional intake structure of migrant workers. Additionally, fat and protein replace carbohydrate as the main nutrition sources for migrant workers. After controlling the income and labor intensity of migrant workers and other factors, urban pension insurance has a positive effect on the intake of fat and protein of migrant workers for they increase by 13.5% and 8.8% respectively. There is no significant effect on the intake of carbohydrates of migrant workers. The calorie intake of migrant workers increases by 6.8% accounting for the change of nutritional intake structure. Endogenous and robustness tests showed that the above conclusions are robust. Heterogeneity analysis showed that there is no significant difference in the effect of urban pension insurance on calorie intake of migrant workers in different income levels and age groups.
RESUMO: Este artigo usa os dados da pesquisa de "Emprego e demanda alimentar dos trabalhadores migrantes urbanos" para analisar empiricamente o impacto do seguro patrimonial urbano na estrutura de ingestão nutricional dos trabalhadores migrantes. O estudo constatou que: o seguro-pensão urbano mudou a estrutura de ingestão nutricional dos trabalhadores migrantes. Gordura e proteína substituíram os carboidratos e se tornaram a principal fonte de nutrição dos trabalhadores migrantes. Depois de controlar fatores como a renda e a intensidade do trabalho dos trabalhadores migrantes, o seguro de pensão urbana aumentou significativamente a ingestão de gordura e proteína dos trabalhadores migrantes em 13,5% e 8,8%, respectivamente, enquanto a ingestão de carboidratos dos trabalhadores migrantes não foi afetada. Significativamente afetado. A transformação da estrutura de ingestão nutricional dos trabalhadores migrantes aumentou sua ingestão calórica em 6,8%. Os testes de endogenia e robustez mostram que as conclusões acima são robustas. A análise de heterogeneidade mostra que não há diferença significativa no efeito do seguro previdenciário urbano sobre o aumento da ingestão de calorias para trabalhadores migrantes de diferentes níveis de renda e diferentes grupos etários.

Aim: Self.expandable metallic stent (SEMS) placement has been considered as the preferred treatment to relieve jaundice in nonsurgical patients. However, 50% of stents become stenosed within 3.6 months due to tumor ingrowth and epithelial hyperplasia. This study aims to evaluate the feasibility and efficacy of a newly designed brachytherapy biliary drainage catheter (BBDC) loaded with 125I seeds for palliation of malignant biliary obstruction (MBO). Methods: In this prospective study, patients with unresectable MBO underwent BBDC placement after SEMS placement at our center from September 2017 to April 2019. Results: A total of 21 patients with MBO were enrolled. The technical and clinical success rates were 100%. Total bilirubin, direct bilirubin, alanine aminotransferase, alkaline phosphatase, cancer antigen 19.9, and carcinoembryonic antigen levels significantly decreased during the 1.month follow.up (P < 0.05). Four patients (19%) had minor complications. During the median follow.up of 299 days, 13 patients (61.9%) developed stent occlusion. The 6.month stent patency and survival rates were 73.5% and 79.2%, respectively. The median stent patency and survival were 279 and 454 days, respectively. Conclusion: The use of BBDC loaded with 125I seeds is a feasible and effective method to prolong biliary stent patency in patients with MBO

Objective:To observe the changes of neutrophil to lymphocyte ratio and lung function of patients defined by different TCM syndromes with acute exacerbation of chronic obstructive pulmonary disease.Methods:A total of 181 patients with acute exacerbation of chronic obstructive pulmonary disease in our hospital from January 2016 to Novenber 2018 were included and divided into 5 groups accoding to different TCM syndromes, which were wind-cold invading lung syndrome (26), external cold and internal fluid syndrome (40), phlegm-heat obstructing lung syndrome (48), phlegm-dampness blocked syndrome (48), an heart spirit confused by phlegm syndrome (19). Then tested the blood for each group, and calculated NLR; tested c-reactive protein, and lung function, and measured with COPD Assessment Test (CAT) and Modified British Medical Research Council (mMRC); conducted 6MWT, then the BODE index and Charlson Comorbidity Index (CCI) scores were calculated.Results:The NLR, CRP level in patients with external cold and internal fluid syndrome and an heart spirit confused by phlegm syndromeby phlegm were significantly higher than those of other syndrome ( P<0.05 or P<0.01), and FEV1% Pred was significantly lower than that of phlegm-dampness blocked syndrome ( P=0.024); the 6-minute walking distance of patients with external cold and internal fluid syndrome was significantly shorter than that of phlegm-heat obstructing lung syndrome and phlegm-dampness blocked syndrome ( P=0.006, P=0.024). The comparison of mMRC grades among the syndromes was statistically significant ( F=26.367, P=0.049). The BODE index of patients external cold and internal fluid syndrome was higher than that of patients phlegm-heat obstructing lung syndrome ( P=0.015), and the CCI score of patients an heart spirit confused by phlegm syndrome was higher than that of patients phlegm-dampness blocked syndrome ( P=0.012). The BODE index of patients with external cold internal fluid syndrome was significantly higher than that of phlegm-heat obstructing lung syndrome ( P=0.015). The CCI score of patients with mental disorder caused by phlegm was significantly higher than that of phlegm-dampness blocked lung syndrome ( P=0.012). Conclusions:There were significantly differences in neutrophil to lymphocyte ratio, CRP and 6-minute walking distance among different TCM syndromes in patients with acute exacerbation of chronic obstructive pulmonary disease. The inflammation in patients with external cold and internal fluid syndrome and mental disorder caused by phlegmare much severe, but there might be no difference in dyspnea and prognosis among TCM syndromes.

BACKGROUND: Lentiviral vectors have been widely used as exogenous transgenic vectors. However, a recombinant lentiviral vector containing rat diacylglycerol kinase y (DGKy) gene has not been reported. OBJECTIVE: To construct lentiviral overexpression vector of rat DGKy by homologous recombination. METHODS: Total RNA was extracted from the brain tissue of adult Sprague-Dawley rats, and the cDNA obtained by PCR was used as a template to amplify the 5'-end 1 029 bp and the 3'-end 1 362 bp of the rat DGKy gene CDS. Then, the two homologous recombination fragments were ligated into the plasmid vector. The positive clones were confirmed by PCR and DNA sequencing. The CMV-rat DGKy-GFP lentiviral vector and the lentiviral packaging system were co-transfected into 293T cells for virus packaging and lentivirus was collected to infect 293T cells. The expression of GFP in infected 293T cells was observed under fluorescence microscope. Real-time PCR and western blot assay were used to detect the relative expression of DGKy mRNA in infected 293T cells. RESULTS AND CONCLUSION: The results of PCR simplification and sequencing indicated that the CMV-rat DGKy-GFP lentiviral vector was successfully constructed. In 293T cells infected with CMV-rat DGKy-GFP lentivirus, the expression of GFP was observed under fluorescence microscope and the DGKy mRNA expression was increased significantly than that of the vector group by real-time PCR (P < 0.01). Western blot assay results showed that the DGKy protein expression of the selected GFP-positive 293T cells was increased very significantly (P < 0.001). To conclude, the rat DGKy lentiviral overexpression vector has been successfully constructed and maintains high expression in 293T cells.

@#[Abstract] Objective: To explore whether gambogic acid can enhance the sensitivity of glioma U251 cells to temozolomide and further explore its mechanism. Methods: U251 cells were cultured in vitro and divided into blank control group, gambogic acid treatment group, temozolomide alone treatment group and combined treatment group. The cells survival rates of cells in each group was detected by CCK-8 assay. Flow cytometry was used to detect cell apoptosis and changes in ROS level. Western blotting was used to detect the changes in protein expressions. Results: CCK-8 results showed that the cells survival rates of the four groups after treatment for 24 h were (98.65±3.68)%, (93.58±2.47)%, (66.81±2.39)% and (38.65±4.13)%, respectively. It can be seen that the combined treatment could significantly increase the inhibitory effect of temozolomide on U251 cells. The proportion of apoptotic U251 cells in the combined treatment group was (61.43±2.58)%, which was significantly higher than that of (26.68±1.82)% in the temozolomide-treated group. Combined treatment of gambogic acid and temozolomide could up-regulate ROS level in U251 cells, reduce the expressions of GLUT-3 and p-AKT, and inhibit the GLUT-3/AKT signaling pathway. Conclusion: Gambogic acid combined with temozolomide can enhance the sensitivity of U251 cells to temozolomide by up-regulating ROS level and inhibiting GLUT-3/AKT signaling pathway in U251 cells, and provides a theoretical basis for the application of gambogic acid in the treatment of glioma.
