Effects of virtual reality in phase I cardiac rehabilitation training for elderly coronary heart disease patients after percutaneous coronary intervention / 生理学报

The study aimed to examine the effects of virtual reality (VR) technology-based phase I cardiac rehabilitation (CR) program in elderly coronary heart disease (CHD) patients after percutaneous coronary intervention (PCI). Thirty-six cases of elderly CHD patients who underwent PCI in the First Affiliated Hospital of Chongqing Medical University from June 2022 to April 2023 were recruited by convenience sampling method. The patients were randomly assigned by means of random digital table method to two study groups: control group (n = 18), which received conventional nursing intervention after PCI, and experimental group (n = 18), which received a combined program of conventional nursing intervention together with CR program based on VR technology. The 6 min walk test (6MWT), Simple Physical Performance Battery (SPPB), SF-36 scale, Hospital Anxiety and Depression Scale (HADS) and Impact of Events Scale-Revised (IES-R) were tested before and after rehabilitation. Moreover, the incidence of major adverse cardiovascular events (MACE) was recorded at 3 months after PCI. After VR-based CR, the 6MWT distance and SPPB scores of patients in the experimental group were higher than those in control group (P < 0.05). The HADS scores and IES-R scores of the patients in the experimental group were lower than those in control group (P < 0.01), and the difference in SF-36 scale scores was not statistically significant between two groups (P > 0.05). The incidence of MACE was not significantly different at 3 months after PCI (P > 0.05). These results suggest that VR-based phase I CR program mitigates the degree of PCI postoperative stress, anxiety, and depression in elderly CHD patients, however, enhances the resistance to fatigue and does not increase the risk of adverse cardiac events, suggesting it is a safe intervention.

Tyrosine kinase inhibitor (TKI) was administered during induction and consolidation chemotherapy. Patients who underwent hematopoietic stem cell transplantation received TKI as maintenance therapy. Results: Of them, 91.1% (144/158) patients achieved complete remission (CR) after 1-2 courses of induction. CR rate was 90.5% (57/63) for patients in Hyper-CVAD/MA group and 91.6% (87/95) for patients in CHALL-01 group. There was no difference in CR rates between the two groups (χ(2)=0.057, P=0.811) . The last follow-up was June 2018. A cohort of 134 CR patients could be used for further analysis, among them, 53 patients received Hyper-CVAD/MA regimen and other 81 patients received CHALL-01 regimen. The molecular remission rates were significantly higher in CHALL-01 group (complete molecular response: 44.4%vs 22.6%; major molecular response: 9.9% vs 18.9%) (χ(2)=7.216, P=0.027) . For the patients in Hyper-CVAD/MA group, the 4-year overall survival (OS) was 44.81% (95%CI: 30.80%-57.86%) and the 4-year disease free survival (DFS) was 37.95% (95%CI: 24.87%-50.93%) . For patients received CHALL-01 regimen, the 4-year OS was 55.63% (95%CI: 39.07%-69.36%) (P=0.037) and 4 year DFS was 49.06% (95%CI: 34.24%-62.29%) (P=0.015) , while there was no significant difference in 4 year cumulative incidence of relapse (CIR) (P=0.328) or cumulative incidence of nonrelapse mortality (CI-NRM) (P=0.138) . The rate of pulmonary infection was lower in patients received CHALL-01 regimen compared with patients received Hyper-CVAD regimen (43.4% vs 67.9%, χ(2)=7.908, P=0.005) . Conclusions: Outcome with CHALL-01 regimen appeared better than that with the Hyper-CVAD/MA regimen in Ph(+) ALL, which has lower incidence of pulmonary infection, higher molecular remission rate and better OS and DFS.

Effectiveness of self-management behavior intervention on type 2 diabetes based on self-determination theory / 北京大学学报(医学版)

OBJECTIVE@#To provide autonomy support from three dimensions based on self-determination theory (SDT), i.e. professional support, peer support, family support, and to investigate whether this intervention can improve diabetes self-management behavior and glycemic control of diabetic patients, and to analyze the influencing factors of the effect.@*METHODS@#Using convenient sampling method, three communities were selected respectively in Beijing. Each community selected health service stations with similar conditions as different intervention groups. The diabetic patients managed by the station who were eligible for inclusion were recruited into this intervention group. The community stations were divided into three groups. The routine intervention group only issued knowledge manuals and conducted health management according to the requirements of basic public health services. Peer support groups were divided into small groups and carried out doctor-led group activities. Based on doctor-led peer support activities, the doctors and peers were trained to provide autonomy support based on self-determination theory, and their family members were trained in the form of manuals to provide autonomy support, forming a concerted support of the three dimensions. Activity processes and materials were also designed based on SDT. The intervention duration was 3 months, and the main evaluation indexes were HbA1c and patients' self-management behaviors, skills, knowledge, and self-efficacy scores.@*RESULTS@#Before and after the intervention, the HbA1c of routine intervention group were 7.40%±1.37%, 7.30%±1.18%. The HbA1c of peer support group before and after the intervention were 7.33%±1.15% and 7.13%±1.27%. The HbA1c of autonomy support group before and after the intervention were 7.42%±1.22% and 6.78%±0.80%. Before and after the intervention, the self-management score in routine intervention group was 10.54±2.28 and 10.80±2.15, the score in peer support group was 11.09±1.89 and 11.40±1.78, the score in autonomy support group was 10.34±1.99 and 11.10±1.65, respectively. The HbA1c and self-management score increased higher in autonomy support group than in the other two groups. After intervention, the control rate in autonomy support group was higher than in the other two groups. According to the multi-factor analysis, the value of HbA1c after intervention was positively related to the baseline HbA1c, and negatively related to self-management behavior. The value in autonomy support group was higher than in routine intervention group. Baseline self-management behavior, self-efficacy, knowledge, skill, family support, autonomy support, peer support and age were positively correlated with the change of behavior.@*CONCLUSION@#self-management behavior intervention based on self-determination theory can effectively promote self-management behavior and glycemic control of diabetic patients, and the effect is better than single peer support activities.

Study on the role of autophagy in heme oxygenase 1 preventing hepatic ischemia/reperfusion injury in rats / 中华危重病急救医学

Objective To identify the role of autopahgy in the protective mechanism of heme oxygenase 1(HO-1) against hepatic ischemia/reperfusion (I/R) injury.Methods Forty healthy male Sprague-Dawley (SD) rats were randomly (random number table) divided into five groups (n =8 in each group),namely sham group,model group,cobalt protoporphyrin (CoPP) group,zinc protoporphyrin (ZnPP) group and 6-amino-3-methylpurine (3-MA) group.Partial hepatic I/R model was established by clamping the pedicles of left and median lobes for 1 hour and reopening for 6 hours in rats,and the rats in sham group were only received celiotomp without hepatic I/R.In the CoPP group,CoPP (a HO-1 inducer,5 mg/kg) was administered i.p 24 hours before I/R.In the ZnPP or 3-MA group,besides pretreatment with CoPP,the rats were given ZnPP (a HO-1 inhibitor,25 mg/kg) or 3-MA (an autophagy inhibitor,30 mg/kg) i.p 1 hour before I/R.Serum alanine aminotransferase (ALT) was determined with automatic biochemistry analyzer.The hepatic pathological scores (PS) were determined under light microscope using hematoxylin-eosin (HE) staining.The hepatocyte apoptosis index (AI) was assessed with terminal dexynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining.Autophagosomes in liver tissue were counted under electron microscope.The mRNA expressions of HO-1,caspase-3,Beclin-1 and Atg-5 in the liver were determined by reverse transcription-polymerase chain reaction (RT-PCR).The HO-1 activity was also measured by the generation of bilirubin with the method of double-wave spectrophotometry.Results Compared with the sham group,the level of serum ALT significantly increased in the I/R group (U/L:560.3±73.6 vs.49.1 ± 13.8,P ＜ 0.01),HE staining showed a severe hepatic injury (PS:12.0±2.0 vs.1.3±0.9,P ＜ 0.01),TUNEL staining showed a higher hepatocytes apoptosis and the expression of caspase-3 significantly increased [AI:(19.38±3.07)％ vs.(3.25±1.28)％,caspase-3 mRNA (2-△△CT):4.62±0.40 vs.1.05±0.15,both P ＜ 0.01].However,there was no significant difference in the expression of HO-1 and the genes associated with autophagy between the two groups.In the CoPP group,the hepatic injury was blunted compared with that in the I/R group [ALT (U/L):223.3 ± 34.4 vs.560.3 ± 73.6,PS:5.6 ± 2.3 vs.12.0 ± 2.0,AI:(11.38± 2.39)％ vs.(19.38 ± 3.07)％,caspase-3mRNA (2-△△CT):2.42±0.33 vs.4.62±0.40,all P ＜ 0.01].HO-1 was induced in the CoPP group and autophagy was also increased significantly after I/R when compared with those in the I/R group [HO-1 mRNA (2-△△CT):3.01 ±0.71vs.1.14 ± 0.20,HO-1 activity (pmol ·mg-1 · h-1):259 ± 37 vs.113 ± 26,the number of autophagosomes:8.75 ± 0.87 vs.1.25±0.71,Beclin-1 mRNA (2-△△CT):2.85±0.28 vs.1.15±0.11,Atg-5 mRNA (2-△△CT):2.44±0.25 vs.1.14±0.12,all P ＜ 0.01].In the ZnPP group,the activity of HO-1 was much lower than that in the CoPP group,and as a result autophagy was decreased and liver injury was increased.In the 3-MA group,although there was no difference in the activity of HO-1 compared with that in the CoPP group,autophagy was inhibited,and the protective effect of CoPP was eliminated.Conclusion HO-1 could regulate the level of autophagy during liver I/R,and in turn autophagy might mediate the protective effects of HO-1 against liver I/R injury.

Preoperative Lund-Kennedy endoscopic score, Lund-MacKay CT score, symptom severity score, postoperative Lund-Kennedy score after six months showed no difference between BBF positive group and negative group.</p><p><b>CONCLUSION</b>The presence of BBF is related to the pathogenesis of CRS and the history of nasal surgery.</p>

Comparison of laxative and antioxidant activities of raw, processed and fermented Polygoni Multiflori radix / 中国天然药物

AIM@#To observe the anti-oxidative activity and adverse laxative effect of raw, traditional processed and fermented products of Polygoni Multiflori Radix (PMR), and furthermore, to evaluate the fermentation method used in the processing procedure of PMR.@*METHODS@#In vitro ferric reducing antioxidant power (FRAP) assay was carried out to evaluate the anti-oxidative activity. Modulation of normal defecation and effect on gastrointestinal motility in mice were carried out to investigate their adverse laxative effect.@*RESULTS@#Fermented PMR induced less severe laxative adverse effect than Polygoni Multiflori Radix Praeparata (PMRP). PMR fermented with Rhizopus sp. (FB) could modulate the defecation significantly. The gastrointestinal motility was inhibited by PMRP and PMR fermented with Rhizopus oryzae (FA). FA and FB showed better antioxidant activity than PMRP in 50% and 95% ethanol group. Contents of 2, 3, 5, 4'-tetrahydroxy-stilbene-2-O-β-D-glucoside (TSG) were reduced significantly after traditional processing but maintained after fermentation. Emodin and physcion were increased after traditional processing and fermented with Rhizopus oryzae.@*CONCLUSION@#All processing procedure, including fermentation, might reduce its anti-oxidative activity. However, most of the processed products could lessen the adverse effect on gastrointestinal tract compared to PMR. Fermentation with Rhizopus oryzae was considered as a promising processing method of PMR.

Effects of dachengqi decoction containing serum on the expressions of caveolin-1, eNOS, and NF-kappaB in lipopolysaccharide stimulated human bronchial epithelial cells / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effects of dachengqi decoction (DD) containing serum on the expressions of caveolin-1 (CAV-1), endothelial nitric oxide synthase (eNOS), and nuclear transcription factor-kappa B (NF-kappaB) in lipopolysaccharide (LPS) stimulated human bronchial epithelial cells (HBECs).</p><p><b>METHODS</b>The DD and the DD containing serum were prepared. The in vitro cultured HBECs were randomly divided into 7 groups, i.e., the normal serum control group, the LPS intervention group, the low dose DD serum containing group, the middle dose DD serum containing group, the high dose DD serum containing group, the Western medicine control group, the vehicle serum control group. The effects of DD containing serum at different doses on the mRNA and protein expressions of CAV-1, eNOS, and NF-kappaB were detected using methyl thiazolyl tetrazolium (MTT) colorimetry, Real-time PCR, immunocytochemical assay, and Western blot.</p><p><b>RESULTS</b>The mRNA and protein expressions of CAV-1, eNOS, and NF-kappaB at the basic levels were detected in the HBECs of the normal serum control group. After stimulated by LPS, the mRNA and protein expressions of CAV-1, eNOS, and NF-kappaB increased more significantly in the LPS intervention group than in the normal serum control group (P < 0.01), while DD containing serums at different doses all could suppress the mRNA and protein expressions of CAV-1, eNOS, and NF-kappaB.</p><p><b>CONCLUSION</b>DD containing serum could inhibit the expressions of CAV-1, eNOS, and NF-kappaB in LPS stimulated HBECs.</p>

Clinical and laboratory characteristics of hematological diseases associated with eosinophilia / 中华血液学杂志

<p><b>OBJECTIVE</b>To analyze the clinical and laboratory characteristics of hematological diseases associated with eosinophilia.</p><p><b>METHODS</b>Karyotype analysis was performed by direct method and/or short-time culture of bone marrow cells for R-banding. Fluorescence in situ hybridization (FISH) was performed using PDGFRα, PDGFRβ and FGFR1 break-apart probes.</p><p><b>RESULTS</b>The clinical and hematological findings of 44 patients were diagnosed as hematological diseases associated with eosinophilia. Abnormal karyotypes were detected in 6 cases (13.64%) with karyotyping. The efficiency of the detection of abnormal clone was markedly increased to 29.55% (13/44) with FISH techniques, including 7 cases with FIP1L1-PDGFRα (F/P, 15.91%), 3(6.82%) PDGFRα rearrangement, 2 (4.55%) aberrant PDGFRβ gene and 1(2.27%) FGFR1 rearrangement. Patients being PDGFRα, PDGFRβ or FGFR1 positive (13 cases) or negative (31 cases) showed predominant difference in clinical and laboratory features. The incidence of gut involvement, the absolute count of eosinophils in peripheral blood and the percentage of immature eosinophils in bone marrow were significantly increased in positive patients (P < 0.05).</p><p><b>CONCLUSIONS</b>The hematological diseases associated with eosinophilia are characterized by unique clinical and laboratory features. Karyotyping should be a routine approach to detect the abnormal clone in these diseases. Screening for PDGFRα, PDGFRβ and FGFR1 gene with FISH can provide more genetic information.</p>

Effect of salvianolic acid B on CD14 expression in rats with liver fibrosis / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of salvianolic acid B (SAB), an extract from Radix Salviae miltiorrhizae, on expression of leucocyte differentiation antigen 14 (CD14) in the liver tissue of experimental rats with carbon tetrachloride (CCl4)-induced liver fibrosis.</p><p><b>METHODS</b>Thirty SD rats were randomly divided into three groups, the model group, the treated group, and the control group. The pathological fibrosis changes in liver of rats were observed. Meantime, their liver function was detected by automatic biochemical analyzer. Serum content of endotoxin was assayed by matrix staining, and plasma content of tumor necrosis factor-alpha (TNF-alpha) was detected by radioimmunoassay. mRNA and protein expressions of CD14 in the liver tissue were measured using reverse transcriptional-polymerase chain reaction and immunohistochemistry respectively.</p><p><b>RESULTS</b>All the laboratory parameters, including liver function, degree of liver fibrosis, serum endotoxin levels, plasma TNF-alpha contents, and CD14 mRNA and protein expressions in the model group were higher than those in the control group (all P<0.01). All the aforesaid indices were lowered more in the treated group than in the model group (all P<0.01).</p><p><b>CONCLUSIONS</b>SAB could antagonize the CCl4, induced liver fibrosis in rats. Its mechanism of action was possibly correlated with its effects on down-regulating hepatic CD14 expression and blocking the endotoxin signal transduction pathway.</p>
