[Objective] The aim of this study is to investigate the mechanism and curative effect of cataplasma of Artemisia Argyi by supercritical CO 2 fluid extraction to rat weight, foot swel ing, interleukin-1β, interleukin-17 and tumor necrosis factor-αin the adjuvant arthritis rat models;and afford theoreti-cal evidence for clinical work.[Methods]50 healthy male SD rats were randomly divided into 5 groups:Control group, Model group, Low-dose treatment group, Medium-dose treatment group, High-dose treatment group. Model and al treatment goups took CFA for model ing. After establishing animal models of AA rats, the first group and second group used cataplasm without active drug ingredients. Other groups were given treatment according to dif-ferent drug doses. Assess the joint swel ing degree at different times. Measure the arthritic index and rat weight in two weeks. After 21 days ,detect the cy-tokines level of IL-lβ,IL-17 and TNF-α from the rat's serum and examine the pathological changes of joint observed by HE . [Results]Cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction can significantly reduce rat foot swel ing of the ankle joint pathology ,reduce arthritis score and slow down the weight loss,meanwhile,effectively improve the general daily behavior of rats. The standard of IL-1β,IL-17,TNF-α in serum can be decreased by cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction. The pathological result showed: in the treatment group,the rats synovial hyperplasia the vesselwing reduced, the inflammatory cel infiltration was more decreased than the model group. [Conclusion]The result showed that the cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction had an obvious effect in treating RA. The mechanism was probably that it regulated the immune dis-order of RA.

Objective To investigate the red blood cell in urine after kidney puncture and know the best detection method.Methods Collected three urines of 31 patients after kidney puncture and detected the red blood cell by UF-100 and the hemoglobin by urine dipstick test.At the same time,detect the conductivity of the urine by UF-100.Results Both the UF-100 and urine dipstick test could reflect the decrease of red blood cell after kidney puncture.But both of them had some limits.Sometimes the results of the two method were not relative(κ=0.148).The agreement of two methods was 0.538.Neither of them could reflect the bleeding of the kidney accuracy.Conclusion By the best,we should use both the UF-100 and the urine dipstick test to detect the red blood cell in urine after kidney puncture,at the same time we should consider the conductivity of the UF-100.

Objective: To review the problems existing in the development and application of current electroacupuncture (EA) apparatuses, and provide reference for the development of EA apparatuses. Methods: Related literatures about EA apparatus were derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang) and Chongqing VIP Database (CQVIP) between 2013 and 2017. Literatures about the development of EA apparatuses and the application for experimental research and clinical treatment published in Chinese journals were retrieved, and the development and application of EA apparatuses were summarized. Results: Among the 107 selected literatures, 48 types of EA apparatuses were used, of which only 11 models could be found in the registration list and within the validity period. There was no registration information for the EA apparatus newly developed in the past 5 years. The EA parameters used in experimental research and clinical treatment in Chinese medicine were different, and the combination of stimulation parameters was diverse. Conclusion: At present, most of the new EA products are still in the experimental or research stage, and the transformation of results has not yet been achieved. Moreover, there is no unified standard for the use of EA apparatus and its stimulation parameters in experimental research and clinical treatment, which is not conducive to the standardization process of EA stimulation.

Objective To discuss the nursing management for patients receiving percutaneous fluoroscopy - guided gastrostomy (PFG) for the treatment of dysphagia caused by head and neck cancer. Methods A total of 15 patients with dysphagia caused by head and neck cancer received PFG. Before PFG sufficient preparation and psychological nursing care were carried out for all the 15 patients. After the operation the patients were kept under close observation for any changes in his or her clinical conditions. Proper prevention measures against complications were adopted. Results PFG procedure was successfully accomplished in all 15 patients. Postoperative complications included gastric bleeding (n = 1), stoma infection (n = 1) and proctoptosis (n = 2), and the disorders were recovered after clinical management. After PFG intravenous nutrition was no longer employed in all patients, and enteral nutrition was conducted. The quality of life was significantly improved in all patients. Conclusion PFG is technically - simple and minimally- invasive with fewer complications. This technique provides a new way to give enteral nutrition for patients with dysphagia caused by head and neck cancer. Excellent psychological nursing, sufficient preoperative preparation, comprehensive postoperative nursing care and medical advices at the time of discharge are the key points to ensure a successful PFG.

Objective To discuss the indication , feasibility and curative effect of endovascular treatment for vascular injuries. Methods 7 patients with vascular injuries were treated by endovascular treatment, including 1 cases of pseudoaneurysm ,2 arteriovenous fistula , 3 closed arteriorrhexis and 1 arterial stenosis after vascular operation . All of the patients were treated by twelve stent - grafts and one introcoil stent. Results All cases were technically successful during follow - up for about 3 to 30 months. The blood flow was rebuild and the diseased region was removed effectively after stent operations. There was no extremity ischemia , hemorrhage , engorgement , stent shift ,fragmentation, angiostegnosis and reinjury appeared in these cases during follow - up. Conclusion Endovascular intervention is a new therapeutic approach with advantages of safety , efectiveness and minimal invasiveness. Its long - term eficacy needs to be further evaluated.

Objective: Diffuse muscular calcification was rare myopathological change due to abnormal metabolism of calcium, which was mainly found in dermatomyositis and myositis ossificans progressiva. Here we reported a case of diffuse muscular calcification that clinically mimicked myositis ossificans progressiva. The disease might be a new type of congenital calcium metabolic disease. Methods:A 15-year-old girl developed subcutaneous cysts in the wrist and ankle when she was 1 year old. At the age of 9, she developed recurrent fever with myalgia, fatigue and diffuse muscular calcification. It was difficult for her to squat, run or walk. Protuberance presented in the subcutaneous tissue of her trunk. Some nodules ruptured with outflow of chalky material. ESR, ENA, RF, CRP, PTH, CK were in normal limits. EMG was unremarkable. X-ray confirmed diffuse calcification in the muscle and subcutaneous tissues. Biceps muscle biopsy was performed. Results:Numerous inflammatory cells infiltrated around vessels in the perimyosium with perifascicular muscle fiber atrophy and degeneration. Many RRF and SDH positive fibers were also observed. EM showed tubular reticular inclusions in vascular endothelium. Conclusion: Diffuse muscular calcification indicated existence of systemic calcium metabolic abnormality. As the clinical symptoms and distribution pattern of calcification were different from dermatomyositis with subcutaneous calcification and myositis ossificans progressiva, our case might be a new type of disease. The microvascular changes might result in the lesion of muscle fibers.

Objective To observe the intervention with electroacupuncture(EA) through regulating protein kinase(MAPK/ERK) pathway for cerebral ischemia rats.Methods SD rats were randomized into pseudo-operation group,model group and EA group.And the three groups were divided into 2-hour,one-day and 3-day subgroups according to the observation time.Focal cerebral ischemia(FCI) rat models were established by middle cerebral artery occlusion(MCAO) with heat-coagulation method.EA group received EA on Baihui(GV20) and Dazhui(GV14),qd,for 2 hours,one day and 3 days respectively.The learning and memory abilities of the rats in Y maze test and their neuroethological score were observed.Immunohistochemical method was used to observe the expression of phosphorylated extracellular signal-regulated kinase(p-ERK) after ischemia in CA1 area and CA3 area.Results In the model group,the neuroethological score was markedly increased,time for arriving the safe area in Y maze was prolonged(P

Objective This article was designed to observe the effects of astragalus polysaccharides (APS) on glucose and lipid metabolism, and on expressions of proxisome proliferator activated receptors-α (PPAR-α) and its downstream genes in diabetic hamsters cardiomyopathy. Methods Forty-five hamsters were divided into 3 groups randomly: normal control group (15 normal hamsters), diabetic control group [15 streptozotocin (STZ)-induced diabetic hamsters], and astragalus polysaccharides (APS)-therapy group (15 STZ-induced diabetic hamsters administered with APS 2 g/kg per day orally for 10 weeks). The levels of insulin, C-peptide, myocardial enzymes, glycosylated serum protein (GSP) and lipoprotein of all hamsters were measured. The ultrastructure of myocardium was studied, and the gene and protein expressions of PPAR-α, FATP and ACS were also detected by fluorescent quantitative RT-PCR and Western blot. Results It was shown that Compared with DM group, the levels of GSP, myocardial enzymes and lipoprotein of hamsters in APS-therapy group were lower, the myocardial ultrastructure of hamsters in APS-therapy group was well-protected, and the gene and protein expression of PPAR-α, FATP and ACS of hamsters in APS-therapy group were higher. Conclusions APS is partly effective in treating diabetic cardiomyopathy.

Objective To evaluate the relationship between emergence agitation (EA) during recovery from general anesthesia and postoperative cognitive dysfunction (POCD).Methods Two hundred and eighty ASA Ⅰ or Ⅱ patients,aged 18-70 yr,weighing 52-80 kg,undergoing elective surgery,were included.Anesthesia was induced with midazolam,fentanyl,propofol and cisatracurium.The patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with remifentanil,propofol and cisatracurium.EA was assessed at 15-40 min after extubation by using Post-operative Quality Recovery Scale and the cognitive function was assessed at day 1 before operation and days 1-7 after operation.Patients were divided into POCD or nonPOCD group according to the occurrence of POCD.The general data of patients,preoperative complications and types of surgery were recorded.If there was significant difference between the 2 groups,the factor was analyzed using multi-factor logistic regression to select the risk factor for incidence of POCD.Results The incidence of POCD was 40.7 ％.The results of logistic regression analysis showed that the dangerous degree of the risk factors for POCD in order from high to low were emergence agitation,duration of anesthesia and age.Conclusion EA during recovery from general anesthesia is an independent risk factor for POCD.
