[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 optimize the alcohol precipitation technology of Qingmai granules. Methods:The relative density of liq-uor,the concentration and time of alcohol precipitation were chosen as the factors,the yield of dry extract and content of diosgenin as the indices,the alcohol precipitation technology was optimized by orthogonal test. Results:The optimal alcohol precipitation technology was as follows:the extraction liquid was concentrated till the relative density was 1. 13-1. 18 g·ml-1 ,ethanol was added until the concen-tration was up to 60% with the alcohol precipitation time of 24h. Conclusion:The optimized technology is stable,reasonable and feasi-ble,which can provide experimental basis for the clinical application of Qingmai granules.

Objective To study the reproductive health status in adolescents underwent repeated abortion and their psychosocial behavioral status and to understand their demanding on the knowledge of contraception, so as to provide suggestions on post abortion care. Methods From July ,2007 to May,2008,400 unmarried adolescents who visited doctors and met the following criteria were recruited in the study:①Younger than 24 years old;②Had artificial abortion at least once;③Have been pregnant for 5-10 weeks and asked for artificial abortion. Data were collected through symptom checklist 90 (SCL-90)and anonymous reproductive health questionnaire. The situation of reproductive tract infections (RTIs) were detected through gynecological examination and laboratory tests.The data was analyzed by SPSS 11.5 statistical software. Results The mean age of the subjects was 21. 18 ±2. 46 years. The mean time of previous artificial abortion was 1.96 ± 1.44,with 52% of ≥2 times. Aged less than 20 years old at the first abortion,having sex more than 3 times per week,more than 2 sex partners,and history of painless abortion were associated with repeated abortion in unmarried adolescents. The SCL-90 scores showed that the subjects had higher score of depression, terror, psychiatric symptoms, somatization, interpersonal sensitivity,anxiety and hostility factors than normal population (P < 0. 05). Of the subjects ,34. 5% had history of RTIs, and the current prevalence of RTI was 59. 5% ,and 58. 5% with one kind of RTI and 36. 0% with two kinds of RTI. Of these RTI patients,33. 5% did not present any clinical symptoms. Abortion for more than twice,first sex intercourse occurred at age younger than 18,history of RTI,sex intercourse of more than 3 time per week,multiple sex partners,especially18,history of RTI,sex intercourse of more than 3 time per week,multiple sex partners,especiallyhaving multi sex partner at the same, and poor sex sanitation were risk factors of RTI. Conclusions There are various reproductive health problems among repeated abortion adolescents in mental and physical aspects, lack of knowledge on reproductive health and contraception is the main reason. Improving post-abortion services will be helpful to prevent repeated abortion in adolescents and protect their physical and mental health.

Objective To evaluate the damage to the brochial plexus produced by pulsed radiofrequency (PRF)and radiofrequency thermocoagulation(RFTC).Methods Fifty-five male Wistar rats weighing 250-300 g were randomly divided into 3 groups:groupⅠPRF(n=25):groupⅡRFTC(n=25)and groupⅢnormal control(n=5).The animals were anesthetized with intraperitoneal chloral hydrate.The left brochial plexus was exposed and PRF or RFTC was applied to the left brochial plexus.The voltage and current of the minimal stimulation which elecited muscle twitching and the impedance before and after operation were recorded in group PRF and RFTC.The nerve function was scored according to Tarloo(0=flaccid paresis,5=normal gait)before and at 3d after operation.The animals were killed and the left brachial plexus was removed immediately and at 1, 7,14,30 d after operation(n=5 at each time point)for determination of histopathological changes using microscope.Results The impedance and Tarlov score were significantly decreased after operation as compared to the baseline values before operation in group RFTC and were also significantly lower than in group PRF. Microscopic examination showed that the myelinated nerve fibers exhibited Wallerian degeneration and axon regeneration and the cytochondria in cylindraxile were severely injured or disappeared in group RFTC.The myelinated nerve fibers and the cytochondria in cylindraxile were significantly less injured after operation in group PRF than in group RFTC and returned to normal at 7 d and 30 d respectively.Conclusion The injury to brachial plexus produced by PRF is slighter than that produced by RFTC.
