Application Effect of External Diaphragm Pacemaker Combined with Active Respiratory Circulation Technology in Pulmonary Rehabilitation of Perioperative Lung Cancer Patients

Aim: To explore the application effect of external diaphragm pacemaker combined with active respiratory circulation technology in pulmonary rehabilitation of perioperative lung cancer patients. Methods: A total of 98 lung cancer patients admitted to our hospital from April 2020 to November 2021 were selected as the observation objects, and then divided into a control group and an observation group using the random number table method, with 49 cases in each group. The control group received routine admission guidance and active respiratory circulation training, while the observation group was supplemented with external diaphragm pacemaker on the basis of the control group. The intervention effect was evaluated by blood gas indicators, pulmonary function indicators, diaphragm function indicators, sputum comfort degree, and activity tolerance indicators before and after intervention. Results: Before intervention, there were no significant differences in blood gas analysis indicators, pulmonary function indicators, diaphragm function indicators, sputum comfort degree, and activity tolerance indicators between the two groups (P > 0.05). After intervention, the improvement degree of the above indicators in the observation group was higher than that in the control group (P < 0.05). Conclusions: The application of external diaphragm pacemaker combined with active respiratory circulation technology in pulmonary rehabilitation of perioperative lung cancer patients is significant, which can effectively improve the pulmonary function, blood gas function, and diaphragm function of lung cancer patients after surgery, and improve the activities of daily living and quality of life of patients.

Objective: To study the targeted point and mechanism of the function of the blood-activating and stasis-removing Chinese drugs, Paeoniae Radix 801(PR801) in its cardiovascular protective effects and its specific binding with endothelin 1(ET-1) as well as the dynamics of the two's interactive function by means of using affinity biosensors: IAsys Plus and quartz crystal microbalance (IAQCM). Methods: ET-1 was immobilized on the surfaces of IAQCM by using the new surface modification methods. The PR801 in the solution was detected by modified substrates and the specific binding between PR801 and ET-1 was studied. Results: The curves went up or down after adding PR801.There is specific binding between PR801 and ET-1. The bound mass were 0.458 ng/mm 2 and 133.54 ng/cm 2, respectively. There exists relatively good stability with these two methods. Conclusion: The affinity biosensors: IAQCM can be used to study the interaction mechanism between PR801 and ET-1, providing a new way to study the interaction mechanism of TCM. PR801 can bind ET-1 specifically in the experiments. Therefore, ET-1 is another target that PR801 can bind specifically besides thromboxane A 2.

Analysis of Chemical and Biological Soil Properties in Organically and Conventionally Fertilized Apple Orchards

We compared chemical and biological properties of soils in organically and conventionally fertilized apple orchards in Nagano Prefecture (one of the major apple producing regions in Japan). Five apple orchards with different fertilizer management systems were used for this study. The total carbon and total nitrogen contents were higher in the organically fertilized orchard, while the total phosphorus and total potassium were at similar levels in both organically and conventionally fertilized orchards. The bacterial biomass did not differ between the two orchards, but the N circulation activity was clearly higher in the organically fertilized orchard from April to December. Total carbon from 50,000 to 60,000 mg/kg, total nitrogen at about 3000 to 4000 mg/kg, and a C/N ratio of 15 - 20 were suggested to be suitable conditions for a high level of apple production under an organic fertilizer management system.

Changes of activated circulating endothelial cells and survivin in patients with non-small cell lung cancer after antiangiogenesis therapy

Background Although antiangiogenesis therapy plays an important role in anti-neoplastic treatment with its recognized efficacy and slight adverse effect, there is no prospective clinical trial to define ideal markers for predicting efficacy of antiangiogenic therapy. This study was undertaken to investigate the changes of activated circulating endothelial cells （aCECs） and survivin after anti-angiogenesis therapy and their significance in predicting the efficacy of the therapy. Methods Patients of non-small cell lung cancer （NSCLC） treated with chemotherapy with or without Endostar were observed. The amount of activated CECs was detected by flow cytometry, and the expression of survivin mRNA was determined by real-time polymerase chain reaction （PCR）. Results After treatment, the amount of activated CECs decreased significantly in clinical benefit cases （P=0.021 in chemotherapy alone, P=0.001 in chemotherapy plus Endostar）, increased in disease progressive cases （P=0.015 in chemotherapy alone, but P=0.293 in chemotherapy with Endotatar）. After therapy, the expression of survivin mRNA decreased in clinical benefit cases （P=0.001） and increased in disease progressive cases （P=0.018）. A positive correlation was found between activated CECs and survivin in the chemotherapy group pre- and post-therapy （P=0.001 and 0.021, respectively）, but only in the chemotherapy with Endostar group pre-therapy （P=0.030） rather than post-therapy. A positive correlation was found between the decreased activated CECs after therapy and time to progression （TTP） （r=0.322, P=0.012）; a negative correlation was found between the amount of survivin mRNA in serum post-therapy and -l-I-P（r= -0.291, P=0.048）. Conclusions Activated CECs and survivin may be ideal markers forecasting efficacy and prognosis of NSCLC. The former can reflect more sensitively antiangiogenic efficacy and the latter is more sensitive to shrinkage or swelling of tumors. Their combination can evaluate more accurately the efficacy of antiangiogenic therapy of NSCLC.

Supplementing Qi and activating blood circulation method to treat vertebrobasilar dolichoectasia with posterior circulatory watershed infarction:a case report of two patients

Vertebrobasilar dolichoectasia(VBD),a rare posterior circulation vascular variant disease,is an important risk factor for many acute cerebrovascular diseases.An insufficient understanding of VBD often leads to misdiagnose.Two cases of VBD that were initially diagnosed as posterior circulation watershed infarction are reported here.Absence of common causes of stroke including hypoperfusion,blood system diseases,carotid and aortic dissection,and eosinophil elevation,the symptoms of the 2 patients met the diagnostic criteria of VBD.Both patients displayed symptoms that were in line with the Traditional Chinese Medicine(TCM)syndrome pattern of"Qi deficiency and blood stasis".Accordingly,they were comprehensively treated with Supplementing Qi and activating blood circulation method.The clinical manifestations of the 2 patients were remarkably improved and no recurrence of watershed infarction was found in a 1-year follow-up.A detailed medical history and laboratory examination are capable of improving diagnostic accuracy of VBD.TCM treatment based on syndrome identification might be a promising candidate for VBD management.

Efficacy and safety of activating blood circulation and removing blood stasis of Traditional Chinese Medicine for managing renal fibrosis in patients with chronic kidney disease:a systematic review and Meta-analysis

OBJECTIVE:To evaluate the efficacy and safety of activating blood circulation and removing blood stasis in terms of Traditional Chinese Medicine(TCM) for managing renal fibrosis(RF) in patients with chronic kidney disease(CKD).METHODS:We searched randomized controlled trials(RCTs) from eight databases.RESULTS:Sixteen eligible studies with 1,356 participants were included in this study.Compared to treatment with Western Medicine(WM) alone,the combined treatment with activating blood circulation and removing blood stasis in terms of TCM(ARTCM) and WM to manage RF in patients with CKD significantly ameliorated type Ⅳ collagen(C-Ⅳ)(SMD:-2.17,95% CI:3.01 to-1.34),type Ⅲ procollagen(PC-Ⅲ)(SMD:-1.08,95% CI:-1.64 to-0.53),laminin(LN)(SMD:-1.28,95% CI:-1.65 to-0.90),transforming growth factor β 1(TGF-β1)(SMD:-0.65,95% CI:-1.18 to-0.12),serum creatinine(Scr)(SMD:-1.36,95% CI:-1.85 to-0.87),blood urea nitrogen(BUN)(MD:-1.51,95% CI:-2.59 to-0.43),and 24 h urine protein(24h Upro)(SMD:-1.23;95% CI:-1.96 to-0.50).The level of hyaluronic acid(HA) was similar in both types of treatment(SMD:-0.74,95% CI:-1.91 to 0.44).The subgroup analysis showed that the duration of 8 weeks might affect the concentration of C-Ⅳ,PC-Ⅲ,and LN(P < 0.05).The effectiveness of the longer duration to C-Ⅳ,PC-Ⅲ,and LN was not certain.However,the result should be interpreted in care.The safety of the treatment using ARTCM and WM could not be evaluated because a few studies had reported adverse effects.The results of the Meta-analysis were not stable enough.There was publication bias for the reports on Scr(P = 0.001),C-Ⅳ(P = 0.001),PC-Ⅲ(P = 0.026),and LN(P = 0.030) and no publication bias for the reports on BUN(P = 0.293).The quality of evidence varied from low to very low.CONCLUSIONS:The combined treatment using ARTCM and WM to manage RF in patients with CKD has some advantages over treatment with WM alone.High-quality RCTs need to be conducted for the strong support.

Activating Blood Circulation to Remove Stasis Treatment of Hypertensive Intracerebral Hemorrhage:A Multi-Center Prospective Randomized Open-Label Blinded-Endpoint Trial

Objective： To investigate the efficacy and safety of the Chinese herbal therapeutic regimen of activating blood circulation （TRABC） in treatment of hypertensive intracerebral hemorrhage （HICH）. Methods： This was a multi-center prospective randomized open-label blinded-endpoint （PROBE） trial with HICH admitted to 12 hospitals. Totally 240 participants were randomized to the treatment group treated with TRABC in addition to conventional Western treatment or the control group with conventional Western treatment equally for 3 months. Primary outcome was degree of disability as measured by modified Rankin Scale （mRS）. Secondary outcomes were the absorption of hematoma and edema, National Institutes of Health Stroke Scale （NIHSS） scores and patient-reported outcome measures for stroke and Barthel activities of daily living index. Adverse events and mortality were also recorded. Results： After 3 months of treatment, the rate of mRS 0-1 and mRS 0-2 in the treatment group was 72.5% and 80.4%, respectively, and in the control group 48.1% and 63.9%, respectively, with a significant difference between groups （P〈0.01）. Hematoma volume decreased significantly at day 7 of treatment in the treatment group than the control group （P=0.038）. Average Barthel scores in the treatment group after treatment was 89.11 ＋ 19.93, and in the control group 82.18 ＋ 24.02 （P=0.003）. NIHSS scores of the two groups after treatment decreased significantly compared with before treatment （P=0.001）. Patient-reported outcomes in the treatment group were lower than the control group at day 21 and 3 months of treatment （P〈0.05）. There were 4 deaths, 2 in each group, and 11 adverse events, 6 in the treatment group and 5 in the control group. Conclusion： The integrative therapy combined TRABC with conventional Western treatment for HICH could promote hematoma absorption thus minimize neurologic impairment, without increasing intracerebral hematoma expansion and re-bleeding.

A Multi-Center Randomized Double-Blind Placebo-Controlled Trial of Xiongshao Capsule(芎芍胶囊)in Preventing Restenosis after Percutaneous Coronary Intervention:A Subgroup Analysis of Senile Patients

Objective：To evaluate the safety and efficacy of Xiongshao Capsule（芎芍胶囊,XS）,consisting of Chuangxiongol and paeoniflorin,in preventing restenosis after percutaneous coronary intervention（PCI） in senile coronary heart disease（CHD） patients.Methods：A multi-center,randomized,double-blind,placebo-controlled trial was conducted.A total of 335 CHD patients were randomly assigned to treatment with oral administration of XS,or a placebo for 6 months after successful PCI.A clinical follow-up was performed at 1, 3 and 6 months after PCI and an angiographic follow-up was scheduled at 6 months.The primary endpoint was angiographic restenosis defined as a luminal stenosis≥50%in follow-up.The secondary endpoints were combined incidence of death,target lesion nonfatal myocardial infarction,repeat target-vessel angioplasty,and coronary artery bypass graft surgery（CABG）.The follow-up for the above clinical endpoint events was continued to 1 year after PCI.Results：The subgroup analysis of 152 senile patients（68 cases angiographic follow-up） showed that the restenosis rates tended to reduce in the XS group as compared with that in the placebo group （24.32%vs.38.71%,P0.05）,and the minimum lumen diameter（MLD） significantly increased in the follow-up （2.15±0.84 for XS vs.1.73±0.91 for placebo,P0.05）.The incidence of recurrent angina at 3 and 6 months after PCI was also significantly reduced in the XS group（4.11%and 12.33%） as compared with those in the placebo group（17.72%and 43.04%）,but there was no significant difference in the combined incidence of clinical outcomes（6.85%in the XS group vs.11.39%in the placebo group,P0.05）.No significant adverse reactions occurred within the 6-month follow-up period in the XS group.Conclusion：Administration of XS in addition to standardized Western medication for 6 months is demonstrated to be safe and effective in reducing post-PCI recurrent angina and inhibiting luminal restenosis after PCI in senile CHD patients.

Effect of Chinese Drugs for Activating Blood Circulation and Detoxifying on Indices of Thrombosis,Inflammatory Reaction,and Tissue Damage in A Rabbit Model of Toxin-Heat and Blood Stasis Syndrome

Objective： To observe the regulatory effect of Chinese drugs for activating blood circulation （ABC） and for activating blood circulation and detoxifying （ABCD） on indices of thrombosis, inflammatory reaction, and tissue damage in a rabbit model of toxin-heat and blood stasis syndrome. Methods： Fifty-four rabbits were randomized into the normal control group, model group, simvastatin group （simvastatin, 0.93 mg/kg per day）, ABC group [Xiongshao Capsule （~ff_）, 0.07 g/kg per day], and ABCD group [Xiongshao Capsule, 0.07 g/kg per day, and Huanglian Capsule （-~L^t）, 0.14 g/kg per day]. All except the normal control group received a single injection of bovine serum albumin and were fed with high-fat diets for 6 weeks. At the end of week 4 of giving high- fat diets, a dose of endoxitin was given by ear vein injection, and a randomized 2-week treatment was initiated. At the end of treatment, blood lipids, circulating endothelial cells, and the pathological changes of the aortic arch were assessed. The serum levels of matrix metalloproteinases （MMP-9）, tissue inhibitors to metalloproteinase （TIMP-1）, granule membrane protein-140 （GMP-140）, plasminogen activator inhibitor-1 （PAl-l）, high-sensitivity C-reactive protein （hs-CRP）, interleukin-6 （IL-6）, and tumor necrosis factor- ~ （TNF- oL ） were determined. Results： Compared with the model group, ABCD group showed decreased serum triglycaride （TG） level, improvement in the pathological change in the aortic arch, and reduction in the number of circulating endothelial cells （4.00_＋ 1.41 per 0.9 p~ L for ABCD group vs 7.83_＋ 1.72 per 0.9 μL for the model group）. In addition, the levels of serum GMP-140, PAl-l, and IL-6 in ABCD group were also significantly reduced [0.79＋0.20 ng/mL, 5.23± 1.39 ng/mL, 40.64 ± 10.11 pg/mL for ABCD group vs 1.08 ± 0.31 ng/mL, 7.28± 2.01 ng/mL, 54.44 ± 13.56 pg/mL for the model group, respectively, P〈0.05]. A trend showing improvement in the indices of thrombosis, inflammatory reaction, and tissue damage was observed in the ABC group when compared to the model group, but the changes were not statistically significant （P〉0.05）. Conclusions： Chinese drugs for activating blood circulation and detoxifying have beneficial effects on regulating indices of thrombosis （GMP-140 and PAl-l） and inflammatory reaction （IL-6） in rabbit model with toxic-heat and blood stasis. The effect of the activating blood circulation and detoxifying drugs in regulating the levels of serum GMP-140, PAl-l, and IL-6 was superior to that of the activating blood circulation drugs.

Effect of Chinese Herbal Medicine for Activating Blood Circulation and Detoxifying on Expression of Inflammatory Reaction and Tissue Damage Related Factors in Experimental Carotid Artery Thrombosis Rats

Objective：To observe the pharmaceutical effect of Chinese drugs for activating blood circulation （Xiongshao Capsule,XSC,芎芍胶囊）and for activating blood circulation and detoxification（Xiongshao Capsule and Huanglian Capsule,XSHLC,黄连胶囊）in terms of the indices of thrombosis,inflammatory reaction and tissue damage related factors in experimental carotid artery thrombosis rats.Methods：Fifty Wistar rats were randomly divided into the sham operation group,the model group,the Simvastatin group（SG）,the activating blood circulation（ABC）group,and the activating blood circulation and detoxifying（ABCD）group,with 10 rats in each group.Simvastatin（1.8 mg/kg）,XSC（0.135 g/kg）and XSHLC（0.135 g/kg）were administered to Simvastatin,ABC and ABCD group by gastrogavage,and an equal volume of normal saline was given to the sham operation group and the model group.After 2 weeks of successive medication,the rats in the model and all drug therapy groups were made into experimental carotid artery thrombosis model.The serum levels of matrix metalloproteinases（MMP-9）,tissue inhibitors to metalloproteinase（TIMP-1）,granule membrane protein-140（GMP-140）,tissue-type plasminogen activator（t-PA）,high-sensitivity C-reactive protein（hs-CRP） and interleukin-6（IL-6）were detected with enzyme-linked immunoassay 24 h later.Results：Compared with the model group,the levels of serum GMP-140,hs-CRP,IL-6 and MMP-9 were significantly decreased,and the level of t-PA was significantly increased in the ABC and ABCD group（P〈0.05）,while the level of serum hs-CRP in ABCD group decreased significantly compared with that in the ABC group（P〈0.05）.Conclusions：Chinese drugs both for activating blood circulation and for activating blood circulation and detoxifying have good effects on regulating indices of thrombosis,inflammatory reaction and tissue damage in experimental carotid artery thrombosis rats.The effect of activating blood circulation and detoxifying drugs on regulating the level of serum hs-CRP is superior to that of activating blood circulation drug alone.

Effects of Zhizi Chuanxiong Capsule (栀子川芎胶囊) on Abnormal Methylation in Rabbits with Atherosclerosis

Objective： To investigate the effects of Zhizi Chuanxiong Capsule（ZCC, 栀子川芎胶囊） on abnormal DNA methylation in a rabbit model of atherosclerosis（AS）. Methods： After 1 week of adaptive feeding, 48 New Zealand white rabbits were randomly divided into 4 groups： a control group（n=12） fed with normal diet for 22 weeks; a model group（n=12） fed with high fat diet for 14 weeks followed by 8 weeks of normal diet feeding; a low-dose ZCC group（n=12） fed with high fat diet and low-dose ZCC for 14 weeks, followed by 8 weeks of normal diet and low-dose drug; a high-dose ZCC group（n=12） fed with high fat diet and high-dose drug for 14 weeks, followed by 8 weeks of normal diet and high-dose drug. After 22 weeks of feeding, blood samples were taken from the rabbit ear vein, and the genomic DNA was extracted for methylation immunoprecipitation sequencing（Medip-seq）. The aorta tissues were collected for hematoxylin-eosin（HE） staining. Results： Eight rabbits died during the feeding process. HE staining showed that the size of the lipid deposition on vessel wall and atherosclerotic plaque formation were reduced in both low-and high-dose group. The Medip-seq results showed that there were 146 abnormally methylated genes（including both hypermethylated gene and hypomethylated genes） in the model group, compared with the control group. Gene Ontology（GO） and Pathway analysis showed that these abnormally methylated genes were found to be involved in multiple AS-related functions and pathways, such as protein kinase C activity, cholesterol transport, mitogen-activated protein kinase（MAPK） signaling pathway, peroxisome proliferater-activated receptor signaling pathway, vascular smooth muscle contraction, inflammation and so on. The abnormal methylated genes in AS model group were altered in both low-and high-dose groups： low-dose ZCC could change 72 of the 146 abnormally methylated genes, highdose ZCC could change 71. Through GO and Pathway analysis, these altered methylated genes were involved in protein kinase C activity, inflammatory pathway, MAPK signaling pathway, vascular endothelial growth factor signaling pathway, etc. Conclusion： ZCC could treat AS through regulating the abnormal hypermethylated and hypomethylated genes in AS rabbit model.
