RESUMO

ObjectiveTo observe the clinical effect of Yiqi Liangxue Shengji Formula (益气凉血生肌方, YLSF) on recurrence of angina pectoris and quality of life at eight weeks after perecutaneous coronary intervention (PCI). MethodsEighty-two coronary artery disease (CAD) patients with qi deficiency and blood stasis and binding of stasis and heat syndrome who had underwent PCI were randomly divided into two groups with 41 patients each in the treatment group and the control group. Based on conventional western medicine after PCI, patients in the treatment group orally took YLSF granules while those in the control group were administered with placebo, one dose daily for 8 weeks. The recurrence rate of angina pectoris and readmission rate within eight weeks after PCI were recorded. Before and after treatment, total traditional Chinese medicine (TCM) syndrome score, Seattle Angina Questionnaire (SAQ) scores (physical limitation, angina stability, angina frequency, treatment satisfaction and disease perception), and the SF-36 scores for quality of life (physical and mental health) were evaluated. The adverse reactions during medication in both groups were recorded. ResultsWithin eight weeks after PCI, the recurrence rate of angina pectoris in the treatment group (4/41, 9.76%) was significantly lower than that in the control group (11/41, 26.83%, P<0.05). The readmission rate in the treatment group was 2.44% (1/41), while that in the control group was 12.20% (5/41), with no significantly statistical difference (P>0.05). After treatment, total TCM syndrome score significantly decreased in both groups, while in terms of quality of life, the SAQ scores on domains of angina stability, angina frequency and disease perception as well as SF-36 total scores, physical health and mental health scores significantly increased (P<0.05 or P<0.01). Compared between the two groups, total TCM syndrome score was significantly lower in the treatment group than the control group (P<0.01), while no significant differences were found in SAQ scores and SF-36 total, physical and mental health scores (P>0.05). No adverse reactions occurred in both groups during the treatment period. ConclusionYLSF can reduce the recurrence rate of angina pectoris within eight weeks after PCI for coronary artery disease, and can improve the TCM syndrome score, and have sound safety, with comparable effect to that of placebo in improving postoperative short-term quality of life.

RESUMO

Objective To investigate the impacts of forkhead box M1(FOXM1)on the proliferation,invasion,and drug resistance of gastric cancer cells by regulating the circular RNA circ_NOTCH1.Methods Western blotting and real-time quantitative PCR were performed to determine the expression of FOXM1 protein and circ_NOTCH1,respectively,in the gastric cancer tissue,para-carcinoma tissue,human normal gastric mucosa epithelial cell line GES-1 and gastric cancer cell lines MGC-803,HGC-27,and BGC-823.BGC-823 cells were classified into the following groups:control,short hairpin RNA FOXM1(sh-FOXM1)and negative control(sh-NC),small interfering RNA circ_NOTCH1(si-circ_NOTCH1)and negative control(si-NC),and sh-FOXM1+circ_NOTCH1 overexpression plasmid(sh-FOXM1+pcDNA-circ_NOTCH1)and sh-FOXM1+negative control(sh-FOXM1+pcDNA).CCK-8 assay and clone formation assay were employed to measure the cell proliferation,and Transwell assay to measure cell invasion.After treatment with 1.0 mg/L adriamycin for 48 h,the cell resistance in each group was analyzed.Western blotting was employed to determine the expression levels of FOXM1,proliferating cell nuclear antigen(PCNA),Bax,multi-drug resistance-associated protein 1(MRP1),and multi-drug resistance gene 1(MDR1).RNA pull-down and RNA immunoprecipitation were employed to examine the binding of circ_NOTCH1 to FOXM1 protein.Results Compared with those in the para-carcinoma tissue,the expression levels of FOXM1 protein and circ_NOTCH1 in the gastric cancer tissue were up-regulated(all P<0.001).Compared with GES-1 cells,MGC-803,HGC-27,and BGC-823 cells showed up-regulated expression levels of FOXM1 protein and circ_NOTCH1(all P<0.001).Compared with the control group and sh-NC group,the sh-FOXM1 group with down-regulated expression of FOXM1 protein and circ_NOTCH1 showed decreased optical density value,clone formation rate,cell invasion number,and cell viability,down-regulated expression of PCNA,MRP1,and MDR1,and up-regulated expression of Bax protein in BGC-823 cells(all P<0.001).Compared with the control group and the si-NC group,the si-circ_NOTCH1 group with down-regulated expression of circ_NOTCH1 showed decreased optical density value,clone formation rate,cell invasion number,and cell viability,down-regulated expression of PCNA,MRP1,and MDR1,and up-regulated expression of Bax protein in BGC-823 cells(all P<0.001).Compared with sh-FOXM1 group and sh-FOXM1+pcDNA group,the sh-FOXM1+pcDNA-circ_NOTCH1 group with up-regulated expression of circ_NOTCH1 showed increased optical density value,clone formation rate,cell invasion number,and cell viability,up-regulated expression of PCNA,MRP1,and MDR1,and down-regulated expression of Bax protein(all P<0.001).FOXM1 protein was able to interact with circ_NOTCH1.Conclusion Interference with FOXM1 may inhibit the proliferation,invasion,and drug resistance of gastric cancer cells by silencing circ_NOTCH1 expression.

RESUMO

Mitophagy is one of the important targets for the prevention and treatment of myocardial ischemia/reperfusion injury (MIRI). Moderate mitophagy can remove damaged mitochondria, inhibit excessive reactive oxygen species accumulation, and protect mitochondria from damage. However, excessive enhancement of mitophagy greatly reduces adenosine triphosphate production and energy supply for cell survival, and aggravates cell death. How dysfunctional mitochondria are selectively recognized and engulfed is related to the interaction of adaptors on the mitochondrial membrane, which mainly include phosphatase and tensin homolog deleted on chromosome ten (PTEN)-induced kinase 1/Parkin, hypoxia-inducible factor-1 α/Bcl-2 and adenovirus e1b19k Da interacting protein 3, FUN-14 domain containing protein 1 receptor-mediated mitophagy pathway and so on. In this review, the authors briefly summarize the main pathways currently studied on mitophagy and the relationship between mitophagy and MIRI, and incorporate and analyze research data on prevention and treatment of MIRI with Chinese medicine, thereby provide relevant theoretical basis and treatment ideas for clinical prevention of MIRI.

RESUMO

Acute coronary syndrome (ACS) is one of the leading causes of death in cardiovascular disease. Percutaneous coronary intervention (PCI) is an important method for the treatment of coronary heart disease (CHD), and it has greatly reduced the mortality of ACS patients since its application. However, a series of new problems may occur after PCI, such as in-stent restenosis, no-reflow phenomenon, in-stent neoatherosclerosis, late stent thrombosis, myocardial ischemia-reperfusion injury, and malignant ventricular arrhythmias, which result in the occurrence of major adverse cardiac events (MACE) that seriously reduce the postoperative benefit for patients. The inflammatory response is a key mechanism of MACE after PCI. Therefore, examining effective anti-inflammatory therapies after PCI in patients with ACS is a current research focus to reduce the incidence of MACE. The pharmacological mechanism and clinical efficacy of routine Western medicine treatment for the anti-inflammatory treatment of CHD have been verified. Many Chinese medicine (CM) preparations have been widely used in the treatment of CHD. Basic and clinical studies showed that effectiveness of the combination of CM and Western medicine treatments in reducing incidence of MACE after PCI was better than Western medicine treatment alone. The current paper reviewed the potential mechanism of the inflammatory response and occurrence of MACE after PCI in patients with ACS and the research progress of combined Chinese and Western medicine treatments in reducing incidence of MACE. The results provide a theoretical basis for further research and clinical treatment.

RESUMO

Patients who are bedridden are for a long-time prone to develop bedsores, especially in the hip and sacral areas and limbs, which causes eczema, ulcers, infection and other complications, resulting in pain and more medical costs. Therefore, the medical staff of the Second Affiliated Hospital of Zunyi Medical University designed and developed a kind of anti-bedsore turning pad, and has obtained the national utility model patent (ZL 2021 2 3004923.9), which is suitable for various long-term bedridden patients. The anti-bedsore turning pad includes the center axis of the turning pad, and ventilation pad 1 and ventilation pad 2 designed on the left and right of turning pad center axis. Under the ventilation pad 1 and the ventilation pad 2, the air pad 1 and the air pad 2 are respectively designed. There is a bedspread connected with ventilation pad 1 and ventilation pad 2 on the inflatable pad 1 and the inflatable pad 2. Through the design of inflatable pad 1 and inflatable pad 2, the left and right of the anti-bedsore turning pad can be lowered or raised independently, which is convenient for the patient's body to tilt and turn over, and can significantly reduce the number of nursing staff and the burden of nursing staff when turning over. In addition, it is convenient to replace the force site at any time and reduce the occurrence of pressure ulcers caused by long-term pressure on the force site. Through the design of ventilation cushion 1 and ventilation cushion 2, the internal gas flow of the turning pad can be made, and the ventilation between the patient and the turning pad can be kept dry, so as to reduce the occurrence of eczema, ulcers or infection and other complications, and ultimately reduce the occurrence of bedsores. In addition, through the design of the most superficial limb pad, the patient's limb can be appropriately elevated or massaged, which increases the comfort of the patient. The anti-bedsore turning pad is simple and effective, and can be widely used in long-term bedridden patients.

RESUMO

Objective:To investigate the effects of regulation of GATA6 expression by long non-coding RNA(lncRNA)GATA6 antisense RNA 1(GATA6-AS1)on the proliferation,apoptosis,and metastasis of 5-fluorouracil(5-FU)resistant gastric cancer(GC)cells SGC7901/5-FU,and to explore the underlying mechanisms. Methods:Parental SGC7901 cells and SGC7901/5-FU cells were used as controls(treated with blank culture medium).Empty vector pcDNA3.1(control for GATA6-AS1 overexpression),recombinant vector pcDNA3.1-GATA6-AS1(for GATA6-AS1 overexpression),shNC(negative control for GATA6-AS1 silencing)or shGATA6-AS1(for GATA6-AS1 silencing)were transfected into SGC7901/5-FU cells by Lipofectamine 2000 to overexpress or silent GATA-AS1.The mRNA expression of GATA6-AS1 and GATA6 in cells of different treatment groups were examined by real-time fluorescence quantitative PCR.After 5-FU treatment,the proliferation,migration,invasion and apoptosis were analyzed by CCK-8 assay,wound-healing assay,Transwell assay,and flow cytometry(FCM)assay,respectively.The protein expression levels of Bax,Bcl-2,Caspase 3 and GATA6 in different treatment groups were examined by Western blotting.The stability of GATA6 mRNA was evaluated after α-amanitin treatment.The relationship between GATA6-AS1 and GATA6 was studied by RNA pull-down experiment.Furthermore,the SGC7901 cell transplantation tumor model was established using Balb/c nude mice,and the grouping was the same as in vitro experiments with 12 mice in each group.The tumor growth was recored and the tumor inhibition rate was calculated after 5-FU treatment.The histopathological changes of tumor tissue in each group was assessed by HE staining.The protein expression of proliferating cell nuclear antigen(PCNA)in tumor tissues of nude mice in each group was detected by Western blotting. Results:Compared with parental SGC7901 cells(control group),the expression of GATA6-AS1 and GATA6 mRNA was significantly downregulated in SGC7901/5-FU cells(P<0.05);the proliferation,migration and invasion of SGC7901/5-FU cells was significantly decreased while the apoptosis of SGC7901/5-FU cells was significantly decreased(P<0.05);the protein expression levels of GATA6,Bax and Caspase 3 were significantly decreased while that of Bcl-2 was significantly increased(P<0.05).Compared with SGC7901/5-FU-pcDNA group,the above changes showed opposite trends in SGC7901/5-FU cells overexpressing GATA6-AS1.Compared with SGC7901/5-FU-shNC group,the expression of GATA6-AS1 and GATA6 mRNA was significantly downregulated in GATA6-AS1-silencing SGC7901/5-FU cells(P<0.05);the proliferation,migration and invasion of GATA6-AS1-silencing SGC7901/5-FU cells was significantly decreased while apoptosis of GATA6-AS1-silencing SGC7901/5-FU cells was significantly decreased(P<0.05);the protein expression levels of GATA6,Bax and Caspase 3 were significantly decreased while that of Bcl-2 was significantly increased(P<0.05).GATA6-AS1 can increase the stability of GATA6 mRNA and positively regulate the expression of GATA6.In vivo characterization showed that,compared with mice transplanted with parental SGC7901 cells,the tumor volume and PCNA protein expression in tumor tissues were significantly increased in mice transplanted with drug resistant SGC7901/5-FU cells after 5-FU treatment(P<0.05).Mice in SGC7901/5-FU-GATA6-AS1 group showed significantly reduced tumor volume and PCNA protein expression compared with the SGC7901/5-FU-pcDNA group(P<0.05),and pathological analysis of the tumor tissues revealed milder development of GC in SGC7901/5-FU-GATA6-AS1 group.Whereas,mice in SGC7901/5-FU-shGATA6-AS1 group showed significantly increased tumor volume and PCNA protein expression compared with the SGC7901/5-FU-shNC group(P<0.05),and histopathological analysis of the tumor tissues revealed severer development of GC in SGC7901/5-FU-shGATA6-ASl group. Conclusion:Overexpression of GATA6-AS1 can promote the expression of GATA6,inhibit the growth of GC cells,and thus reverse the resistance of SGC7901/5-FU cells to 5-FU.

RESUMO

Objective::To study the therapeutic and inflammatory effects of gentiopicroside(GPS) on adjuvant-induced arthritis (AA) rats. Method::The 36 male SD rats were randomly divided into six groups, namely the model group, GPS groups (low, medium and high dose), and the methotrexate (MTX) group, with six rats in each group. AA rats were induced through intradermal injection with 0.1 mL complete Freund's adjuvant (CFA) into the right hind paw, except the normal group. After modeling, rats in each group were treated with drugs for 7 days, once a day. The doses were 30, 60, 120 mg·kg-1 in the GPS groups, and 0.2 mg·kg-1 in the MTX group. The normal group and the model group were intragastrically treated with the same volume of normal saline. During the experiment, the paw thickness and paw volume of rats were recorded everyday by the digital vernier calipers and the toe volume measuring instrument. On the seventh day, X-ray and histopathological examination of the ankle joints were performed by the small animal living imaging instrument and hematoxylin eosin stain. Blood samples were collected from the abdominal aorta at the end of the experiment to determine the levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-α in serum by enzyme-linked immunosorbent assay(ELISA) kits. The mRNA levels of IL-6 and TNF-α in synovial tissues were determined by Real-time fluorescent quantitative polymerase chain reaction(Real-time PCR). Result::Compared with the normal group, the results of each index in the model group were significantly different (P<0.01). Compared with the model group, the results of paw volume and paw thickness decreased significantly (P<0.01), TNF-α level decreased significantly (P<0.01), and IL-6 and TNF-α mRNA levels decreased significantly (P<0.05, P<0.01) in drug treated groups. The results of X-ray and histopathological examinations indicated that GPS had a protective effect on the ankle joints of AA rats. Conclusion::GPS has the therapeutic effect on AA rats by inhibiting levels of proinflammatory cytokines in serum and relevant mRNA levels in synovial tissues.

RESUMO

@#Objective To investigate the effects of cranial magnetic therapy on swallowing,articulation function and quality of life in Wallenberg syndrome patients with dysphagia. Methods Patients with Wallenberg syndrome in our hospital from February 2017 to January 2019 July,and randomly divided into two groups,each with 55 cases. The observation group was given routine treatment and cranial magnetic therapy,while the control group was given routine treatment and rehabilitation training. The swallowing,hyoid bone displacement,penetration-aspiration degree,articulation function,and quality of life were assessed by the Kubota’s water swallow test,Videofluoroscopic Swallowing Study,Rosenbek penetration-aspiration scale,dysphagia assessment scale,and World Health Organization Quality-of-Life Scale(WHOQOL-BREF). Results After treatment,the abnormal rate of swallowing function was decreased in the observation group[32.73(18/55) vs 100%(55/55)] and control group[56.36%(31/55) vs 100%(55/55)],and that of the observation group was lower than the control group[32.73(18/55) vs 56.36%(31/55),P<0.05]. The maximal displacement of hyoid bone was increased in both groups after treatment(P<0.05),and was larger in the observation group than in the control group(P<0.05). The proportion of patients at Rosenbek grade 2,grade 3,grade 4 was increased in the observation group,and was higher than that of the control group(P<0.05). The proportion of patients at Rosenbek grade 6,grade 7 and grade 8 was decreased in the observation group,and was lower than that of the control group(P<0.05). The efficiency rate of dysphagia treatment in the observation group was significantly higher than that of the control group[96.36%(53/55) vs 78.18%(43/55),P<0.05]. After treatment,the abnormal rate of articulation function was decreased in the observation group[41.82%(23/55) vs 89.09%(49/55)] and control group[70.91%(39/55) vs 87.27%(48/55)],and that of the observation group was lower than the control group[41.82%(23/55) vs 70.91%(39/55),P<0.05]. After treatment,the effective rate of dysarthria treatment in the observation group was higher than that of the control group[72.73%(40/55) vs 61.82%(34/55),P<0.05]. After treatment,the scores of each dimension and total score of WHOQOL scale were increased in both groups,and were higher in the observation group than in the control group(P<0.05). Conclusion Cranial magnetic therapy can effectively ameliorate the dysphagia and dysarthria for wallenberg syndrome patients with dysphagia,which can also improve the quality of life,and is worthy of promotion.

RESUMO

To target neovasculature and tumor cells, a novel cationic liposome with verteporfin (BPD) active-loaded in lumen (CLL) was designed and its basic in vitro and in vivo behaviors were evaluated in this study. Calcium acetate gradient loading method was applied to encapsulate BPD actively and cationic lipid (2,3-dioleoy-loxy-propyl)-trimethylammonium (DOTAP) was added by post-insertion for the positive charge of CLL. Results of characterization showed that the diameter and zeta-potential of CLL were around 100 nm and 28 mV, respectively. Compared with passive loading liposomes, CLL significantly enhanced the stability of BPD loading. What's more, the loaded BPD in lumen could switch off the fluorescence and photosensitization during blood circulation by homo-fluorescence resonance energy transfer (homo-FRET) effect, leading to the diminished phototoxicity to normal tissues. In vitro cellular uptake and cytotoxicity assay exhibited that positive charge dramatically enhanced the uptake of CLL both in vascular endothelial cells and tumor cells leading to superior therapeutic efficacy. In vivo study further showed that CLL reduced the clearance rate and increased tumor accumulation compared with passive loading group. Quantitative results of exvivo organ indicated that negligible CLL distributed in normal organs contributing to low phototoxicity. Animal experiments were conducted according to the Guidelines of the Experimental Animal Ethics Committee of Peking University Health Science Center and International Animal Experiments. In conclusion, we successfully designed a novel cationic targeting liposome that overcame the limitations of passive loading and significantly enhanced the efficacy of photodynamic therapy.

RESUMO

Since the American Medical Association published the 2011 guidelines for immune thrombocytopenia, China has been the first to update the guidelines for immune thrombocytopenia based on evidence-based medicine. Recently, there have been many breakthroughs in clinical research published, especially the Chinese medical workers have made a prominent contribution to the treatment of the immune thrombocytopenia. However, the references of systematic drug introduction for children, adults, aged and pregnant women are still insufficient, and the first or second line treatment for some patients were ineffective. Therefore, we tried to combine the references to interpret the guidelines, to explore the advantages and disadvantages of each treatment, to find out the bottleneck of clinical treatment, so as to facilitate the implementation and understanding of the guidelines, then update the next guideline.

RESUMO

<p><b>OBJECTIVE</b>To exam the effect and safety of conventional acupuncture (CA) on cardiac arrhythmia.</p><p><b>METHODS</b>Nine medical databases were searched until February 2016 for randomized controlled trials. Heterogeneity was measured by Cochran Q test. Meta-analysis was conducted if I was less than 85% and the characteristics of included trials were similar.</p><p><b>RESULTS</b>Nine qualified studies involving 638 patients were included. Only 1 study had definitely low risk of bias, while 7 trials were rated as unclear and 1 as high. Meta-analysis of CA alone did not have a significant benefit on response rate compared to amiodarone in patients with atrial fibrillation (Af) and atrial flutter (AF) [relative risk (RR): 1.09; 95% confidence interval (CI): 0.79-1.49; P=0.61; I=61%, P=0.11]. However, 1 study with higher methodological quality detected a lower recurrence rate of Af in CA alone as compared with sham acupuncture plus no treatment, and benefits on ventricular rate and time of conversion to normal sinus rhythm were found in CA alone group by 1 study, as well as the response rate in CA plus deslanoside group by another study. Meta-analysis of CA plus anti-arrhythmia drug (AAD) was associated with a significant benefit on the response rate when compared with AAD alone in ventricular premature beat (VPB) patients (RR, 1.19, 95% CI: 1.05-1.34; P=0.005; I=13%, P=0.32), and an improvement in quality-of-life score (QOLS) of VPB also showed in 1 individual study. Besides, a lower heart rate was detected in the CA alone group by 1 individual study when compared with no treatment in sinus tachycardia patients (MD-21.84 [-27.21,-16.47]) and lower adverse events of CA alone were reported than amiodarone.</p><p><b>CONCLUSIONS</b>CA may be a useful and safe alternative or additive approach to AADs for cardiac arrhythmia, especially in VPB and Af patients, which mainly based on a pooled estimate and result from 1 study with higher methodological quality. However, we could not reach a robust conclusion due to low quality of overall evidence.</p>

To optimize the ethanol extraction process for Shenlian formula. On the basis of the pharmacodynamics index for different extraction process routes, the contents of salvianolic acid B, tanshinone ⅡA and berberine, as well as the extraction ratio in different experimental schemes were used as the ethanol extraction examining indexes, and multi-criterion synthesizing grading method was used for data analysis to optimize and verify the ethanol-extraction process conditions in orthogonal experiment. The optimum ethanol extraction process was as follows: adding 60% ethanol, 10 times amount, extracting for 2.0 h each time for a total of 2 times. This extraction process showed good stability and availability.

RESUMO

Objective To explore the hope 1evel in stroke patients and its influencing factors to provide theoretical basis for improving the hope 1evel of patients. Method The general information questionnaire, herth hope index and social support rating scale were used to investigate the hope levels and the related factors among 414 cases of patients with stroke. Results The level of hope for patients with stroke was (34.33±4.15) minutes, at a moderate level. The social support in patients with stroke was (37.95±7.37) minutes. 81.40%stroke patients were below average or below. Logistic regression analysis showed, marital status, stroke type and social support were independent influencing factors of the level of hope in stroke patients (P<0.05), explaining 27.10% of the total variation. Conclusions The main factors influencing the level of hope in stroke patients are marital status, stroke type and social support, according to the level of hope factors affecting the development of personalized intervention measures. The implementation of targeted psychological counseling and health education, social support system of play buffer disease, improve patient confidence to overcome the disease and the level of hope.
