Objective:To systematically analyze the incidence and influencing factors of frailty in elderly patients with hematologic malignancies.Methods:Research on frailty in elderly patients with hematologic malignancies was retrieved from Chinese and English databases such as China National Knowledge Infrastructure, Wanfang Data, PubMed, and Web of Science. The search period was from database establishment to August 23, 2024. Two researchers screened the included studies, conducted quality assessment, and extracted data. Meta-analysis was conducted using Stata 18 and RevMan 5.4.Results:A total of seven studies were included, encompassing 19 076 elderly hematologic malignancy patients, with a frailty incidence of 59% [95% CI (0.48, 0.69) ]. Meta-analysis revealed that age [ MD=4.31, 95% CI (3.67, 4.96) ], gender [ OR=0.88, 95% CI (0.83, 0.93) ], alcohol consumption [ OR=1.67, 95% CI (1.15, 2.44) ], self-care ability [ MD=-1.79, 95% CI (-3.17, -0.41) ], anemia [ OR=6.67, 95% CI (2.94, 15.14) ], infection [ OR=1.81, 95% CI (1.16, 2.84) ], and neuropathy [ OR=2.52, 95% CI (1.38, 4.61) ] were the influencing factors of frailty in elderly patients with hematologic malignancies. Conclusions:The incidence of frailty is high in elderly patients with hematologic malignancies. Elderly patients with hematologic malignancies who are older, female, consume alcohol, have low self-care ability, anemia, infections, and neuropathy are prone to frailty. Healthcare providers can conduct early screening and intervention for high-risk populations of frailty based on risk factors to improve the quality of life for elderly hematologic malignancy patients.

ObjectiveTo investigate the effects of Tongxinluo capsules on traditional Chinese medicine （TCM） syndrome elements and major adverse cardiovascular events （MACEs） in patients with chronic coronary syndrome of Qi deficiency and blood stasis type. MethodsA multicenter and prospective cohort study was conducted. The intervention of Tongxinluo Capsules was used as the exposure factor， and the patients were divided into an exposure group （integrated traditional Chinese and western medicine treatment group） and a non-exposure group （western medicine treatment group）. The patients were followed up for one year. The TCM syndrome element scores were assessed by using a syndrome element diagnosis scale on the day of enrollment and in the third， sixth， and twelfth months， and the incidence of MACE within one year was recorded. ResultsA total of 186 patients were included， with 128 patients in the exposure group and 58 patients in the non-exposure group. There was no significant difference in baseline data between the two groups. Compared with those in the pretreatment period for each group， the Qi deficiency and blood stasis syndrome scores in the treatment and follow-up period were significantly improved （P<0.05）. Compared with the non-exposure group， the exposure group exhibited significantly decreased Qi deficiency syndrome scores in the treatment and follow-up period （P<0.01） and significantly reduced blood stasis syndrome scores in the sixth month （P<0.05）. In the remaining follow-up period， there was no statistically significant difference between the two groups. Compared with that of the non-exposure group， during the treatment period （the third month）， the difference in Qi deficiency and blood stasis syndrome scores of the exposure group was statistically significant （P<0.05， P<0.01）. At the end of the follow-up period， patients in the non-exposure group had a MACE probability of 6.90% （4/58）， higher than 3.13% in the exposure group （4/58）. Compared with patients with angina pectoris who used conventional medicine， patients administered with Tongxinluo Capsules had a relative risk（RR） of 0.45 ［95%confidence interval（95%CI） 0.12-1.75， P=0.26］. There was no significant difference in the incidence of MACE within one year between the two groups. ConclusionTongxinluo capsules can improve the degree of Qi deficiency in patients with chronic coronary syndrome in the short term， and the improvement effect of blood stasis syndrome appears in the medium and long term. They can better improve the Qi deficiency syndrome in the long term. Within one year， the incidence of MACE in the exposure group was lower than that in the non-exposure group.

ObjectiveTo investigate the effect of Tongxinluo capsules on the use of anti-ischemic drugs in patients with chronic coronary syndrome （CCS） of Qi deficiency and blood stasis. MethodA multicenter，prospective cohort study was conducted，with Tongxinluo capsules intervention as the exposure factor. Patients were divided into an exposed group （combination of traditional Chinese and western medicine） and a non-exposed group （western medicine alone），and followed up for one year. The use of anti-ischemic drugs was observed on the day of enrollment and at 3，6，12 months. ResultA total of 186 patients were enrolled，with 128 in the exposed group and 58 in the non-exposed group. There were no statistically significant differences in baseline characteristics between the two groups. At the 3-month follow-up，the types of first-line anti-ischemic drugs used in the exposed group were significantly fewer than those in the non-exposed group （P<0.01），and this difference remained statistically significant at 6 months （P<0.05） but was no longer significant at 12 months. At the 3- and 6-month follow-ups，there were no significant differences between the two groups in the types of second-line anti-ischemic drugs used. However，at the 12-month follow-up，the types of second-line anti-ischemic drugs used in the exposed group were significantly fewer than those in the non-exposed group （P<0.01）. At the 3-month follow-up，both groups showed a reduction in the types of first-line anti-ischemic drugs used compared to baseline （P<0.05），with a more pronounced reduction in the exposed group （P<0.05）. At the 6-month follow-up，the exposed group showed a significant reduction in the types of second-line anti-ischemic drugs used compared to baseline （P<0.05），while no significant changes were observed in the non-exposed group. At the 12-month follow-up，the difference in the types of second-line anti-ischemic drugs between the exposed and non-exposed groups was statistically significant （P<0.05），while there was no significant difference in the types of first-line anti-ischemic drugs. ConclusionTongxinluo capsules can effectively reduce the use of anti-ischemic drugs in patients with CCS of Qi deficiency and blood stasis.

OBJECTIVE To investigate the effects of total glucosides of paeony （TGP） on enhancing efficacy and reducing toxicity of Tripterygium wilfordii polyglycoside （TWP） in the treatment of eczema. METHODS Totally 50 SD male rats were collected to establish eczema model by sensitizing with 2，4-dinitrofluorobenzene-acetone olive oil solution （volume ratio was 4∶1） on the abdominal area and provoking on the back and ear. Model rats were randomly divided into model group， loratadine group （0.9 mg/kg）， TWP group （9.45 mg/kg）， TGP group （162 mg/kg） and compatibility group （TWP 9.45 mg/kg+TGP 162 mg/kg）， with 10 rats in each group. Other 10 rats were collected to set as normal group. Three days after the first sensitization， administration groups were given relevant medicine intragastrically， and normal group and model group were given constant volume of 0.1% CMC-Na solution intragastrically， once a day， for consecutive 21 d. Twenty-four hours later after the final administration， the general condition of rats in each group was observed， and the eczema area and severity index （EASI） were scored； ear swelling degree of rats was measured， and the skinhistomorphology observation and pathological score were performed； protein expressions of p38 mitogen-activated 13938427612@126.com protein kinase （p38 MAPK）， phosphorylated p38 MAPK （p- MAPK） and phosphorylation level of p38 MAPK in rat skin tissue were detected； the levels of inflammatory indexes （interleukin-4， interferon- γ）， liver and kidney function indexes [glutamic-pyruvic transaminase （GPT）， glutamic-oxaloacetic transaminase （GOT）， serum creatinine （SCr） and blood urea nitrogen （BUN）] and oxidant stress indexes [total superoxide dismutase （T-SOD） and malondialdehyde （MDA）] were measured. RESULTS Compared with normal group， EASI score， ear swelling degree， pathological score， protein expressions of p38 MAPK and p-p38 MAPK， phosphorylation level of p38 MAPK， the levels of inflammatory indexes and BUN were all increased significantly in model group （P＜0.05）. Compared with model group， EASI scores， ear swelling degree， pathological scores， protein expressions of p38 MAPK and p-p38 MAPK， phosphorylation levels of p38 MAPK and levels of inflammatory indexes were all improved significantly in administration groups （P＜0.05）. The levels of GPT， GOT， SCr and BUN were increased significantly in TWP group， while the serum levels of GOT and SCr in TGP group and serum level of SCr in loratadine group were all decreased significantly （P＜0.05）. The levels of T-SOD in liver and kidney tissue were all decreased significantly in TWP group and compatibility group， while the levels of MDA were increased significantly （P＜0.05）. The compatibility group showed more obvious effect in improving the ear swelling degree， pathological score， p38 MAPK expression and its phosphorylation level and levels of inflammatory indexes， and could reverse the abnormality of liver and kidney indexes caused by TWP （P＜0.05）. CONCLUSIONS The combination of TGP and TWP has the effects of anti-inflammatory， synergistic and hepatorenal detoxification in eczema model rats. Its mechanism may be associated with down-regulating the expression of serum proinflammatory indexes and inhibiting the activation of p38 MAPK pathway.

Objective:To investigate the correlations between serum E selectin, intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1) and left ventricular geometry and function in patients with obstructive sleep apnea syndrome (OSAS) combined with prehypertension (pre-HT).Methods:A total of 462 patients with pre-HT and OSAS diagnosed by polysomnography (PSG) in the sleep monitoring unit of the Department of Respiratory and Critical Care Medicine at the First Hospital of Shanxi Medical University from July 2019 to July 2022 were restrospectively analysed, and 52 patients with pure pre-HT (pre-HT group) and 73 patients with pure OSAS (OSAS group) in the same period were selected as the control group. OSAS and pre-HT patients were divided into four groups according to left ventricular geometry: normal geometry (NG) group, concentric remodeling (CR) group, eccentric hypertrophy (EH) group and concentric hypertrophy (CH) group. The general clinical data, PSG parameters, blood biochemical parameters and left ventricular structure and function parameters were compared among the six groups. Pearson correlation and multivariate Logistic regression were used to analyze the correlation between E-selection, ICAM-1, VCAM-1, general clinical data, PSG parameters, blood biochemical parameters with left ventricular geometry and function.Results:①Serum E selectin, ICAM-1, and VCAM-1 concentrations increased sequentially from the NG, CR, and EH to CH groups, with the most significant increase in CH group (all P<0.05). In addition, there were statistically significant differences in age, body mass index (BMI), OSAS severity, neck circumference, waist circumference, systolic blood pressure (SBP), diastolic blood pressure (DBP), Glu, lowest oxygen saturation (Lowest-SaO 2), mean oxygen saturation (Mean-SaO 2), percentage of time with oxygen saturation below 90% of total sleep time (T90), left ventricular end-diastolic diameter (LVEDd), interventricular septal thickness (IVST), left ventricular posterior wall thickness (LVPWT), left ventricular mass index (LVMI), relative ventricular wall thickness (RWT), left ventricular ejection fraction (LVEF), peak mitral early diastolic flow velocity/peak mitral late diastolic flow velocity (E/A), E wave deceleration time (DT), A wave duration (AD), and isovolumic relaxation time (IVRT), and overall long-axis longitudinal strain (GLS) and so on(all P<0.05). ②Pearson correlation analysis showed that E selectin was negatively correlated with LVEF, E/A, e′, E/e′, IVRT, and GLS ( r=-0.236, -0.131, -0.224, -0.215, -0.285, -0.336; all P<0.05). ICAM-1 was negatively correlated with LVEF, E, E/A, e′, IVRT, and GLS( r=-0.130, -0.129, -0.104, -0.351, -0.252, -0.259; all P<0.05). VCAM-1 was negatively correlated with E, e′, and IVRT ( r=-0.132, -0.312, -0.387; all P<0.001). ③Multifactorial logistic regression analysis showed that E selectin and VCAM-1 were independently correlated with EH (β=1.139, OR=3.124, P=0.030; β=1.288, OR=3.626, P<0.001) and with CH (β=1.178, OR=3.248, P=0.013; β=1.108, OR=3.028, P<0.001). Conclusions:E selection and VCAM-1 were independently correlated with hypertrophic left ventricular geometry, suggesting that E selectin and VCAM-1 may be involved in the process of abnormal left ventricular structure and function in patients with OSAS combined with pre-HT.

OBJECTIVE To investigate the effect of Compound danshen tablet s o n improving the blood lipid levels and the mechanism of protecting renal functions in hyperlipidemia model rats. METHODS Sixty male SD rats were divided into normal group，model group ，simvastatin combined with （2S）-N-[N-（3，5-difluorophenylacetyl）-L-alanyl]-2-phenylglycine tert butyl （DAPT）group and low-dose ，medium-dose and high-dose groups of Compound danshen tablets ，with 10 rats in each group. Rats in the normal group received routine diet. The other 5 groups were intraperitoneally injected with 75％ yolk emulsion 10 mL/kg， fasting and drinking freely. After 16 h，they were fed high-fat diet for 4 weeks. Simvastatin combined with DAPT group was given simvastatin 0.002 g/kg and DAPT 0.012 g/kg at the same time of modeling. The low-dose ，medium-dose and high-dose groups of Compound danshen tablets were given Compound danshen tablets 0.25，0.5 and 1 g/kg respectively at the same time of modeling ， the normal group and model group were given equal volume of distilled water ，once a day ，for 4 weeks. The serum levels of total cholesterol（TC），triglyceride（TG），creatinine（Cr）and urea nitrogen （BUN）in serum were detected by biochemical method ； kidney coefficient of rats was calculated ；histopathological changes of rat kidney were observed by HE staining ，and the renal injury was scored according to the degree of renal tubular injury and glomerular sclerosis in renal cortex ；expression levels of Notch signal receptor 1（Notch 1），Notch signal ligand 1（Jagged1）and hairy division associated enhancer 1（Hes1）in kidney were detected by immunohistochemistry ；mRNA expressions of Notch 1，Jagged1 and Hes 1 in renal tissue were detected by real-time fluorescence quantitative polymerase chain reaction. RESULTS Compared with normal group ，the serum levels of TG ， TC，Cr and BUN were increased significantly in model group （P＜0.05）；renal coefficient increased significantly （P＜0.05）； pathological changes occurred in renal tissue ，and the scores of renal tubular injury and glomerular sclerosis increased significantly （P＜0.05）；protein and mRNA expressions of Notch1， Jagged1， Hes1 in renal tissue were increased significantly（P＜0.05）. Compared with model group ，serum levels of TG ，TC，Cr and BUN ，renal coefficient ，the scores of renal tubular injury and glomerular sclerosis ，protein and mRNA expression of Notch 1，Jagged1 and Hes 1 in renal tissue were all decreased in low-dose ，medium-dose and high-dose groups of Compound danshen tablets （P＜0.05），and most indexes showed a dose-dependent trend ；the degree of renal lesions was reduced. CONCLUSIONS Compound danshen tablets possess obvious hypolipidemic effect ，and can protect the renal function of hyperlipidemia model rats by down-regulating Notch 1/Jagged1 signal pathway.
