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.

To explore a new way of constructing bioartificial renal tubule assist device (RAD) in vitro and its function of transporting sodium (Na(+)) and glucose and to evaluate the application of atomic force microscope in the RAD construction, rat renal tubular epithelial cell line NRK-52E was cultured in vitro, seeded onto the outer surfaces of hollow fibers in a bioreactor, and then cultured for two weeks to construct RAD. Bioreactor hollow fibers without NRK-52E cells were used as control. The morphologies of attached cells were observed with scanning electron microscope, and the junctions of cells and polysulfone membrane were observed with atomic force microscope. Transportation of Na(+) and glucose was measured. Oubaine and phlorizin were used to inhibit the transporting property. The results showed that NRK-52E cells and polysulfone membrane were closely linked, as observed under atomic force microscope. After exposure to oubaine and phlorizin, transporting rates of Na(+) and glucose were decreased significantly in the RAD group as compared with that in the control group (P<0.01). Furthermore, when the inhibitors were removed, transportation of Na(+) and glucose was restored. It is concluded that a new RAD was constructed successfully in vitro, and it is able to selectively transport Na(+) and glucose.

Objective To observe the effect of intravenous pre-injection of neostigmine on cardiovascular response(CVR) caused by neuromuscular electrical stimulation(NMES) in selective posterior rhizotomy(SPR) for patients with cerebral palsy.Methods 56 patients with cerebral palsy undergoing SPR at lumbarsacral segments under general anesthesia were randomly assigned to 2 groups: intravenous neostigmine 0.04 mg/kg(no more than 1 mg in total) and intravenous atropine 0.02 mg/kg(no more than 0.5 mg in total) 5 min before NMES in group N,and intravenous normal saline 0.12 ml/kg instead in group C.The systolic blood pressure(SBP) and heart rate(HR) at following time points: before skin incision(T1),before intravenous neostigmine/atropine or normal saline injection(T2),1 min after NMES(T3),and 10 min after NMES(T4).Results SBP and HR at T3 in group N were significantly lower than those in group C(P<0.01).No significant difference was found at T1,T2 and T4 between two groups(P>0.05).Cases who needed extra dose of fentanyl during NMES in group N were significantly lower than those in group C(P<0.01).Conclusion Intravenous pre-injection of neostigmine before NMES can effectively decrease the CVR caused by NMES.

Objective To compare MR,CT,and radiography in the detection of arthropathies in patients with hemophilia.Methods Forty-one symptomic joint images in the 14 patients with hemophilia, aged from 11 to 24 years,were used in this study.Each joint had the examinations of radiography,CT and MR within one day.The severity of each joint was staged using conventional radiographic classification. Severe HA patients with stage 5 were excluded from the study.Imaging findings of soft tissue swelling, osteoporosis,epiphyseal overgrowth,joint erosion,cyst,joint space narrowing,bone marrow,joint effusion, hemorrhage,synovial hypertrophy,widened intercondylar notch as well as anterior and posterior crueiate ligaments(only for knee joint)were used for the all imaging comparison.Results The 41 symptomatic joints in 14 patients with hemophilia were classified by radiographic criteria into stage 0(n=5),stage 1(n=7),stage 2(n=6),stage 3(n=8)and stage 4(n=15).Soft tissue swelling or joint effusion was observed in 33 joints by radiographs,in 34 joints by both CT and MR.Joint erosions were demonstrated in 34 joints by MR,in 33 joints by CT and 20 joints by radiographs.Joint cysts were shown in 21 joints by MR,in 18 joints by CT and 9 joints by radiographs.Significant differences in detection of erosion and cyst were found between radiography with either CT(P0.05).MR showed improvement for detecting nlore loci of both erosion and cyst than CT and radiography,and also CT showed the improvement than radiography.Bone marrow edema 14 joints, hemon'hage in 34 joints and synovial hypertrophy in 27 joints were revealed on MR images.Conclusion MRI is superior to CT and conventional radiography in detecting the abnormal changes and should be considered as the first choice among the imaging modafities in evaluating hemophilic arthropathies.

OBJECTIVE:To investigate the effects of 4 polar parts extracts from Li medicine Alpinia oxyphylla fruit on model mice with experimental colitis,and screen the effective parts of A. oxyphylla fruit in the treatment of colitis. METHODS:After 70% ethanol extract dispersed by water,petroleum ether,trichloromethane,ethyl acetate and n-butanol were used in turn to obtain extractions in related parts. 42 mice were randomly divided into modeling group(36 mice)and blank group(6 mice). Mice in mod-eling group were taken 2,4,6-nitrobenzne sulfonic acid method to replicate the experiment colitis. After modeling,model mice were randomly divided into model group,positive group(Sulfasalazine enteric coated tablets,52 g/kg),petroleum ether,trichloro-methane,ethyl acetate,n-butanol extract from A. oxyphylla fruit groups(10 g/kg,calculated by crude drug),6 in each group,in-tragastrically administrated once a day,for 9 d,0.2 mL/10 g;mice in blank group and model group were intragastrically given nor-mal saline. After administration,body mass of mice was determined,disease activity index(DAI)was scored and colonic myelo-peroxidase(MPO),superoxide dismutase(SOD),malondialdehyde(MDA)activities in colon tissue were detected,and the colon pathological changes were observed and scored. RESULTS:Compared with blank group,decrease percentage of body mass,DAI score,MPO and MDA activities in colon tissue in model group were increased(P<0.05 or P<0.01);colon tissue was pathologi-cally changed. Compared with model group,body mass was increased,DAI score,MPO activity and pathological score in each ad-ministration groups were decreased;SOD activities in positive group,n-butanol extract from A. oxyphylla fruit group and ethyl ace-tate extract from A. oxyphylla fruit group were significantly increased,MDA activities in positive group and ethyl acetate extract from A. oxyphylla fruit group were significantly decreased,with statistical significances (P<0.05 or P<0.01). CONCLUSIONS:The 4 polar parts extracs from A. oxyphylla fruit have certain improvement effects on model mice with experimental colitis, in which ethyl acetate and n-butanol parts are preferred.

Objective To measure and assess CT perfusion value for peri-pancreatic metastatic lymph node by using multiple spiral CT (MSCT) with body perfusion software package. Methods The MSCT perfusion imaging was performed for peri-pancreatic metastatic lymph nodes and muscle on a multi-section CT scanner (SOMATOM Sensation Cardiac 64). 4 x 5 mm collimation, 120 kV, 60mA.

The mean blood flow (BF) were measured and analyzed in patients with pathologically proven peri-pancreatic metastatic lymph nodes(n=29)and hyperplastic lymph nodes(n=15) on work station using body perfusion software (Siemens) with deconvolution method. Results The mean BF in peri-pancreatic metastatic lymph nodes were (53.63±18.82) ml·min-1·100 ml-1, in hyperplastic lymph nodes were 29.78±7.52 ml·min-1·100 ml-1, the difference was significant (P<0.001). Conclusions Perfusion imaging of MSCT was useful in differentiation between peri-pancreatic metastatic lymph nodes and hyperplastic lymph nodes.

Objective To preliminarily discuss the efficacy and safety of balloon protection technique in venous sinus in the embolization of lateral sinus dural arteriovenous fistula.Methods FromDecember 2012 to August 2016,7 consecutive patients with lateral sinus dural arteriovenous fistula embolized with Onyx under the protection of venous sinus balloon were enrolled retrospectively. Their clinical data,imaging data,and follow-up results were analyzed.Results In 7 patients,the fistulas of 3 cases were located in the sigmoid sinus and the fistulas of 4 cases were located in the transverse sinus. Immediately after operation, 5 patients were embolized completely and 2 were embolized mostly. All balloon protected venous sinuses maintained patency. Seven patients were followed up clinically and the follow-up time was 6-43 months. No new neurological deficits were observed. All 7 patients received whole DSA reexamination and the follow-up time was 6-11 months. It is suggested that 5 patients were completely cured,among them,the venous sinuses were patent in 4 cases,the venous sinus was occluded in 1 case;the fistula was stable and venous sinus patency in 1 case;and 1 had newly complicated venous sinus occlusion.Conclusion At the same time of embolization of the fistulas,the dural arteriovenous fistulas were embolized under the protection of venous sinus balloon. It could maintain long-term patency of venous sinus and be conductive to maintaining the stability of the embolization effect.
