Effect of acupuncture on diaphragmatic function in patients with AECOPD typeⅡ respiratory failure evaluated by ultrasound detection / 中国针灸

OBJECTIVE@#To observe the therapeutic effect of acupuncture combined with western conventional therapy on type Ⅱ respiratory failure of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and evaluate the effect of acupuncture on diaphragmatic function and prognosis by bedside ultrasound.@*METHODS@#A total of 111 patients with AECOPD type Ⅱ respiratory failure were randomized into an acupuncture group, a conventional treatment group and a non-acupoint acupuncture group, 37 cases in each one. The routine AECOPD nursing care and treatment with western medicine were provided in the 3 groups. Additionally, in the acupuncture group, acupuncture was applied at Dingchuan (EX-B 1), Feishu (BL 13), Taiyuan (LU 9), Danzhong (CV 17) and Zhongwan (CV 12), etc. In the non-acupoint acupuncture group, acupuncture was given at the points 5 to 10 mm lateral to each of the acupoints selected in the acupuncture group. Acupuncture was given once every day, 30 min each time, consecutively for 10 days in the above two groups. Separately, before treatment, on day 3, 7 and 10 of treatment, arterial partial pressure of oxygen (PaO@*RESULTS@#On day 3, 7 and 10 of treatment, PaO@*CONCLUSION@#Acupuncture as adjunctive therapy achieves significant therapeutic effect on AECOPD type Ⅱ respiratory failure. It improves diaphragmatic function, promotes oxygenation and relieves carbon dioxide retention of artery, alleviates clinical symptoms and reduces the time of mechanic ventilation and hospitalization. Besides, the bedside ultrasound detection can objectively reflect the effect of acupuncture on diaphragmatic function in the patients with AECOPD complicated with typeⅡrespiratory failure.

Hypolipidemic effect of SIPI-7623, a derivative of an extract from oriental wormwood, through farnesoid X receptor antagonism / 中国天然药物

Farnesoid X receptor (FXR) is a member of the nuclear receptor superfamily of ligand-activated transcription factors. As a metabolic regulator, FXR plays key roles in bile acid and cholesterol metabolism and lipid and glucose homeostasis. Therefore, FXR is a potential drug target for several metabolic syndromes, especially those related to lipidemia disorders. In the present study, we identified small molecule SIPI-7623, a derivative of an extract from Oriental wormwood (Artemisia capillaris), and found that it specifically upregulated the expression of cholesterol-7-alpha-hydroxylase (CYP7A1), downregulated the expression of sterol-regulatory element-binding protein 1c (SREBP-1c) in the liver, and inhibited the expression of ileal bile acid binding-protein (IBABP) in the ileum of rats. We found that inhibition of FXR by SIPI-7623 decreased the level of cholesterol and triglyceride. SIPI-7623 reduced the levels of cholesterol and triglyceride in in vitro HepG2 cell models, ameliorated diet-induced atherosclerosis, and decreased the serum lipid content on rats and rabbits model of atherosclerosis in vivo. Furthermore, SIPI-7623 decreased the extent of atherosclerotic lesions. Our resutls demonstrated that antagonism of the FXR pathway can be employed as a therapeutic strategy to treat metabolic diseases such as hyperlipidemia and atherosclerosis. In conclusion, SIPI-7623 could be a promising lead compound for development of drugs to treat hyperlipidemia and atherosclerosis.

Oral JS-38, a metabolite from Xenorhabdus sp., has both anti-tumor activity and the ability to elevate peripheral neutrophils / 中国天然药物

AIM@#JS-38 (mitothiolore), a synthetic version of a metabolite isolated from Xenorhabdus sp., was evaluated for its anti-tumor and white blood cell (WBC) elevating activities.@*METHOD@#These anti-proliferative activities were assessed in vitro using a panel of ten cell lines. The anti-tumor activities were tested in vivo using B16 allograft mouse models and xenograft models of A549 human lung carcinoma and QGY human hepatoma in nude mice. The anti-tumor interactions of JS-38 and cyclophosphamide (CTX) or 5-fluorouracil (5-Fu) were studied in a S180 sarcoma model in ICR mice. Specific stimulatory effects were determined on peripheral neutrophils in normal and CTX- and 5-Fu-induced neutropenic mice.@*RESULTS@#The IC50 values ranged from 0.1 to 2.0 μmol·L(-1). JS-38 (1 μmol·L(-1)) caused an increase in A549 tumor cell apoptosis. Multi-daily gavage of JS-38 (15, 30, and 60 mg·kg(-1)·d(-1)) inhibited in vivo tumor progression without a significant effect on body weight. JS-38 additively enhanced the in vivo anti-tumor effects of CTX or 5-Fu. JS-38 increased peripheral neutrophil counts and neutrophil rates in normal BALB/c mice almost as effectively as granulocyte colony-stimulating factor (G-CSF). In mice with neutropenia induced by CTX or 5-Fu, JS-38 rapidly restored neutrophil counts.@*CONCLUSION@#These results suggest that JS-38 has anti-tumor activity, and also has the ability to increase peripheral blood neutrophils.

Establishment and evaluation of a bone cancer pain model / 中南大学学报(医学版)

OBJECTIVE@#To explore the feasibility of a bone cancer pain model by injecting the Lewis lung carcinoma cells into the femur bone marrow cavity of C57BL/6 mice.@*METHODS@#Sixty clear grade male C57BL/6 mice (body weight 18 approximately 20 g) were randomly divided into 4 groups(15 in each group). Cancer cell inoculated group: 2*10(6) Lewis lung carcinoma cells in 10 microL PBS were injected into the left femur bone marrow cavity, and the other 3 control groups were injected the heat inactivated Lewis cells, PBS, or a false operation respectively. Spontaneous lifting time and mechanical allodynia threshold of the mice hind paw were measured in the alternative days throughout the experiment. The structural damage of the femur was monitored by radiogram on the 7th,15th, and 23rd day respectively,and the pathohistological changes of the femur bones were observed by HE staining on the same days.@*RESULTS@#Those mice that received intra-femur innoculation of Lewis lung carcinoma cells gradually developed the spontaneous pain, which was began on the 11th day after the innoculation, and followed by mechanical allodynia. The course of flinch lasted in the later experimental session. The 50% Von Frey threshold was significantly decreased on the 13th day after the innoculation, and the mechanical allodynia lasted the whole experimental period. On the 23rd day after the innoculation, X-ray film showed that the medullary cavity of ipsilateral distal femur was filled with tumor cells, and the cortical bone became thick; furthermore, the tumor cells invaded the peripheral muscles.@*CONCLUSION@#Injecting the Lewis lung carcinoma cells into the femoral medullary cavity of C57BL/6 mice can successfully establish a murine bone cancer pain model, and the murine model shows much resemblance compared with the human bone cancer pain.

Renal Hemodynamics in Patients with End Stage Renal Disease / 中华高血压杂志

Objective To investigate the relationship between refractory hypertension and renal hemodynamics in end stage renal diseases (ESRD) patients.Methods ESRD patients were classified into:patients with refractory hypertension (group A) and patients with normal blood pressure(group B).Renal hemodynamic indices were ex- amined by duplex ultrasonography.Fasting serum lipid (TC,TG,HDL-C,LDL-C,Lp(a),ox-LDL) and serum parathyroid hormane (PTH) were determined in all patients.Results Significant differences were found in renal hemodynamic indices such as peak systolic velocity (PSV),mean flow velocity (MV),pulsatility index (PI),renal- aortic ratio (RAR) and in clinical index such as Lp(a) and ox-LDL between the two group.Refractory hyperten- sion patients had lower renal hemodynamic indices and higher Lp(a) and ox-LDL levels than in patients with con- trolled BP.Logistic regression analysis revealed that refractory hypertension was related with PSV,EDV,Pl and RAR,but not relevant with sex,age,dialysis time,hematocrit,BUN,creatinine,TC,TG,HDL-C,LDL-C, PTH,MV and RI.Conclusion Atherosclerotic renal artery stenosis and severe disorder in renal hemodynamics is likely the cause for refractory hypertention in ESRD patients.The rise of serum Lp(a) and ox-LDL might acceler- ate renal artery atherosclerosis.
