Objective To evaluate clinical therapeutic efficacy and adverse effecacy of transcatheter arterial chemoembolization(TACE)combined with radiofrequency capacitive heating(RCH) for metastatic hepatic carcinoma(MHC). Methods Thirty-nine cases of MHC were enrolled in this study and divided into two groups: study group(n = 19)and control group(n = 20). Before therapy, the Karnofsky's score of the patients was all beyond 60. Results The carcinoma growth rate of the study group was -(0.38 ? 0.22), while that of the control group was -(0.13 ? 0.25), showing significant statistical difference(P 0.05). Conclusion The therapeutic effect of MHC can be further improved by the treatment of TACE combined with radiofrequency capacitive heating without increase of adverse side effects.

OBJECTIVE: To investigate the mechanism of Chinese herbal recipe Weichang'an (WCA) in inducing cell apoptosis of human gastric cancer grafted onto nude mice. METHODS: The high performance liquid chromatography was used for monitoring the stability of WCA. A human gastric cancer cell line SGC-7901 grafted in nude mouse was used as the animal model. The mice were divided into untreated group and two experimental groups. Animals in the two experimental groups received either WCA over a 34-day period or 5-fluorouracil (5-FU) over a 6-day period starting at the 8th day after grafting. Animals in the untreated group received normal saline on an identical schedule. Animals were killed 41 days after being grafted. To assess the effect of the treatment on tumor, the tumor weight was determined by the electron balance immediately after the animals were killed. SP immunohistochemical method was used to detect the expression of proliferating cell nuclear antigen (PCNA) in grafts. Apoptotic indices (AI) of the tumor cells were examined by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate fluorescence nick end labeling (TUNEL) method. SP method was also used to detect the expressions of cleaved caspase-3, caspase-8 and caspase-9. SYBR green dye I real-time quantitative polymerase chain reaction (real-time quantitative [corrected] PCR) was used to assess the related gene alterations in mRNA level. The expressions of phospho-Stat3 (Tyr705) and bcl-2 proteins were detected by using SP method. RESULTS: Compared with the untreated group, tumor growth was significantly inhibited by treatment of WCA or 5-FU (P<0.01, respectively). The tumor inhibition rate in the WCA-treated group was 48.70% and that in the 5-FU-treated group was 60.10%. The average labeling index (LI) for PCNA in the WCA-treated group and 5-FU-treated group was significantly decreased as compared with that in the untreated group, respectively. The AI of human gastric cancer grafted in the nude mice detected by using TUNEL method was significantly increased to (9.72+/-4.51)% in the WCA-treated group, while it was (2.45+/-1.37)% in the untreated group. 5-FU-treated group was also found a significantly increased AI compared with the untreated group. The expressions of cleaved caspase-3 and caspase-9 in the WCA-treated group and 5-FU-treated group were significantly increased as compared with those in the untreated group. But caspase-8 showed no significant alteration either in the WCA-treated group or in the 5-FU-treated group. The expression levels of Stat3 (2(-)delta delta C(T))=0.16) and bcl-2 (2(-)delta delta C(T))=0.10) detected by using real-time quantitative [corrected] PCR were lower in the WCA-treated group than those in the untreated group. The expressions of phospho-Stat3 (Tyr705) and bcl-2 in the WCA-treated group were significantly decreased as compared with those in the untreated group. CONCLUSIONS: Chinese herbal recipe WCA can inhibit gastric cancer cell SGC-7901 growth in vivo, induce gastric cancer cell apoptosis and suppress the cell proliferation. WCA induces apoptosis through the caspase-9 and caspase-3 pathway in vivo. Its mechanism might be involved in the down-regulation of Stat3 and bcl-2 genes.

Objective:To explore the effects and feasibility of group reminiscence therapy on improving the negative emotions of the elderly inpension sectors.Methods:From April to June 2019, using convenient sampling method, a total of 19 elderly people who volunteered and met the selection criteria at two pension sectors in Beijing were selected to participate in a four-week group reminiscence therapy. The scores of the negative emotions, pulse rate changes, behavior changes, and facial photo changes of each subject before and after the intervention were compared, and the relationship between the changes in the negative emotion score and the number of participations was analyzed to evaluate the intervention effect.Results:After intervention, the elderly negative emotion scale score increased and the pulse rate increased, and the difference was statistically significant compared with that before the intervention ( P<0.01) .After the intervention, 15 of the 16 subjects showed observable facial expression changes, and the expression changes after each intervention were different. According to the caregiver's feedback, compared with that before the intervention, the study subjects had different degrees of positive behavioral changes after the intervention. There was no correlation between the change of negative emotion score and the times of participation in the elderly ( P>0.05) . Conclusions:Group reminiscence therapy can significantly improve the negative emotions of elderly people in nursing homes, and has a positive effect on emotional mobilization, which can be used as a normalizing intervention for elderly people to intervene in mental health in nursing homes.

Objective:To systematically review the current situation and risk factors of social isolation among elderly people in Chinese communities.Methods:The research on social isolation of elderly people in Chinese communities was electronically searched on China National Knowledge Infrastructure, WanFang Data, VIP, China Biology Medicine disc, PubMed, Embase, Web of Science, and Cochrane Library. The search period was from database establishment to August 1, 2023. Two researchers independently conducted literature screening, quality evaluation, and data extraction, and used Stata 17.0 software to conduct Meta-analysis on the incidence and risk factors of social isolation among elderly people in the community.Results:A total of 29 articles were included, with a total of 49 713 samples. Meta-analysis showed that the incidence of social isolation among elderly people in Chinese communities was 29.5%. Advanced age, education below college level, poor self-rated health, lack of exercise, coexistence of chronic diseases, impaired daily living activities, hearing loss, depression, lack of spouse, low family care, low social support, and low social participation were the main risk factors for social isolation among elderly people in the community ( OR ranging from 1.57 to 3.34, P<0.05) . Conclusions:The incidence of social isolation among elderly people in Chinese communities is high, and there are many risk factors. Medical and nursing staff should strengthen early screening for social isolation among the elderly and provide early intervention for the risk factors.

This study was performed to explore the effects of berberine(BBR)and berbamine(BA)on the apoptosis and activity of eosinophils,and to provide new ideas for the treatment of eosinophil-related diseases.Anticoagulated whole blood was taken from hospitalized patients,and eosinophils were purified by magnetic bead sorting technology,and the cell purification rate was compared by using flow cytometry.The purified eosinophils were cultured and stimulated with different concentrations of BBR and BA,and the apoptosis of eosinophils was observed using immunofluorescence microscopy.Flow cytometry was used to detect the apoptosis rate,reactive oxygen species(ROS)release,mitochondrial membrane potential,and CD11b,CD62L and CD63 molecular expression of eosinophils.Data showed that 10 μmol/L BBR displayed significant anti-apoptosis effect on eosinophils at 18 h,24 h,48 h,however,100 μmol/L and 150 μmol/L BBR displayed significant apoptosis-promoting effects on eosinophils at 24 h,48 h,especially in the early stage.BA at 5 μmol/L,15 μmol/L and 25 μmol/L showed significant apoptosis-promoting effects on eosinophils at 24 h,48 h,especially in the late stage.In eosinophils,BA stimulated the production of ROS and the decrease of mitochondrial membrane potential in a concentration-dependent manner,reaching the maximum effect at 25 μmol/L,while BBR stimulation did not change mitochondria and ROS.Pretreatment with 25 μmol/L BA significantly inhibited the increase of CD11b expression and the decrease of CD62L expression in eosinophils after eotaxin-2 stimulation.In conclusion,berberine has a bidirectional regulatory effect on the quantity of eosinophils,while berbamine promotes eosinophil apoptosis and inhibits eosinophil activation.Both compounds hold significant potential for regulating the progression of eosinophil-associated diseases,and their regulatory mechanisms need further investigation.

Objective:To explore the causal relationship between gastroesophageal reflux disease (GERD) and sleep disorder using Mendelian randomization (MR); To explore the diagnosis and treatment of sleep disorder with GERD by combining with the TCM theory that "gastric disharmony causing restless sleep".Methods:Genetic loci independent of each other and closely related to GERD were taken as instrumental variables by pooling data from a large-scale genome-wide association study. The causal relationship between GERD and sleep disorder was explored with Mendelian randomization methods, such as Inverse Variance Weighted (IVW), MR Egger, Weighted Median (WME), Simple Mode (SM), Weighted Mode (WM) and MR Multiple Effectiveness Residual Sum and Heteroscedasticity (MR-PRESSO) using OR as an evaluation index.Results:The results of the IVW method showed that GERD led to a 44.3% higher risk of developing sleep disorder ( P=4.96×10 -15, OR=1.443, 95% CI:1.317-1.582); horizontal pleiotropy was detected using the MR-Egger intercept, which was calculated to be P=0.646 ( P>0.05), proving that there was no horizontal pleiotropy in the results; Leave-one-out sensitivity test showed that the results were stable and there were no instrumental variables that strongly influenced the results. Conclusion:GRED is a risk factor for the development of sleep disorder, which is consistent with the TCM theory of "gastric disharmony causing restless sleep".

In recent years, the prevalence of metabolic diseases, including obesity, diabetes, nonalcoholic fatty liver disease, and metabolic syndrome, increased significantly. Fatigue is common in metabolic diseases and may lead to functional disability. This complicated feeling imposes a huge influence on patients with metabolic diseases physically and psychologically, which seriously affects the quality of life and brings serious burden to the social economy. There were an increasing number of researches on fatigue and metabolic diseases. This article reviews the evidences of the linkages between fatigue and metabolic diseases.

Objective To establish a nomogram model for efficiently predicting overall survival(OS)and cancer-specific survival(CSS)in patients with CRCHBM.Method 2239 patients from 2010 to 2019 were retrospectively analyzed from the Surveillance,Epidemiology,and End Results Program(SEER)databases and Wuhan Union Hospital Cancer Center.SEER is randomly assigned to the training and internal validation cohorts,and the Wuhan database serves as the external validation.Cox regression analyses were used to determine the independent clinicopathological prognosis factors affecting OS and CSS,and a nomogram was constructed to predict OS and CSS.The clinical utility of columnar plots was assessed using calibration curves,area under the curve(AUC),and decision curve analysis(DCA).Result OS column line graphs were constructed based on nine independent predictors:age,tumor location,degree of differentiation,tumor size,TNM stage,chemotherapy,primary focus surgery,number of lymph nodes sampled,and serum carcinoembryonic antigen(CEA)level.The C-index of the nomogram to predict the 1-,3-,and 5-year OS were 0.764,0.790,and 0.805 in the training group,0.754,0.760,and 0.801 in the internal validation group,and 0.822,0.874,and 0.906 in the external validation group.CSS column line graphs were constructed based on 3 independent predictors of TNM staging,radiotherapy and chemotherapy.The 1-,3-,and 5-year CSS AUROC values of the training group were 0.791,0.757,and 0.782,respectively.0.682,0.709,0.625 in the internal validation group and 0.759,0.702,0.755 in the external validation group,respectively.The results of receiver operating characteristic curve(ROC),ROC and DCA showed that the use of our model was more effective in predicting OS and CSS than other single clinicopathological features.Conclusion In summary,the nomogram based on significant clinicopathological features can be conveniently used to predict OS and CSS individually in patients with CRCHBM.

Circular RNAs (circRNAs) are a new class of non-coding RNAs, which have been confirmed to regulate insect gene expression and immune response through multiple manners such as competing endogenous RNA (ceRNA) regulatory network. Currently, function of circRNA in honey bee immune response remains unclear. In this study, PCR and Sanger sequencing were performed to validate the back splicing (BS) site of ame_circ_000115 (in short ac115). RT-qPCR was used to detect the expression profile of ac115 in larval guts of Apis mellifera ligustica stressed by Ascosphaera apis. Dual-luciferase reporter gene assay was conducted to verify the binding relationship between ac115 and ame-miR-13b. Interference of ac115 in larval guts was carried out by feeding specific siRNA, followed by determination of the effect of ac115 interference on expression of six genes relevant to host immune response. The results confirmed the existence of BS site within ac115. Compared with the un-inoculated group, the expression of ac115 in 4-day-old larval gut of the A. apis-inoculated group was up-regulated with extreme significance (P < 0.000 1), while that in 5- and 6-day-old larval guts were significantly up-regulated (P < 0.05). The brightness of specific band for ac115 in 4-, 5- and 6-day-old larval guts of the siRNA-circ_000115-fed group gradually became weak, whereas that of the siRNA-scrambl-fed group was pretty high without obvious variation. Compared with that of the siRNA-scramble-fed group, the expression of ac115 in 4-day-old larval gut of the siRNA-circ_000115-fed group was significantly down-regulated (P < 0.05), whereas that of the 5- and 6-day-old larval guts were down-regulated with extreme significance (P < 0.001). Ame-miR-13b was truly existed and expressed in A. m. ligustica larval guts, and there was true binding relationship between ac115 and ame-miR-13b. Compared with that of the siRNA-scramble-fed group, the expression of antimicrobial peptide genes hymenoptaecin and abaecin in 6-day-old larval gut of the siRNA-circ_000115-fed group was significantly up-regulated (P < 0.05), while that of ecdysone receptor (Ecr) was down-regulated with extreme significance (P < 0.01). These results indicate that ac115 is truly expressed in A. m. ligustica larval guts, BS site truly exists within ac115, and effective interference of ac115 in A. m. ligustica larval guts can be achieved via feeding siRNA. Moreover, ac115 potentially regulates Ecr expression through adsorption of ame-miR-13b and expression of hymenoptaecin and abaecin using a non-ceRNA manner, further participating in host stress-response.
