Recombinase polymerase amplification (RPA) is a novel isothermal DNA amplification technology first re-ported in 2006 by Piepenburg et al.This technology has been shown to typically work at temperatures ranging from 25 to 43℃and can detect products within 5-20 min.RPA technology requires little instrumentation for the nucleic acid amplifi-cation reaction and can be performed not only in PCR tubes , but also in simple devices′such as paper .Combined with probe-based detection methods or lateral flow dipstick assay , it can perform quantitative or visual detection respectively . RPA is a technology that is potentially ideal for point-of-care diagnosis and disease prevention and control ,characterized by high sensitivity, high efficiency, high specificity and user-friendliness.This paper introduces the advantages and develop-ment of RPA technology in reaction conditions and product detection ,summarizes the current applications of this technolo-gy,and predicts the trend of application of RPA technology in point-of-care diagnosis and disease prevention and control .

Objective To observe the influence of bony extracts of Myospalox fontanierii(MF)on immune function in rats with hypersensitive reactive inflammation induced by Freund's complete adjuvant(FCA).Methods Levels of lymphocyte transferring factor(TF)and interleukin-1(IL-1)were detected by immunological methods.Results Extracts of MF reduced the levels of IL-1 and TF in rats with hypersensitive reactive inflammation induced by FCA;it could also depressed the lymphocytic transformation rate.Conclusion Extracts of MF exert inhibitory effect on rats with hypersensitive reactive inflammation induced by FCA and its mechanism may be related with immunosuppressive action and the inhibition of IL-1 formation.

Objective To study the clinico-pathological features of primary adrenal lymphoma (PAL). Methods 2 cases of PAL were reviewed and studied. Results The age of the 2 patients was 45 and 57.The presenting symptoms were nonspecific.Histologically,the neoplasm was composed of numerous medium-sized cells with round nucleus,usually 1-2 in number and with relatively abundant basophilic cytoplasm.The neoplastic cells showed frequent mitosis.Immunohistochemically,the tumor cells were strongly positive for LCA,L26 and CD74 while negative for UCHL-1,S-100 protein and CK. One case was discharged 3 months after operation because of dyscrasia and the other was lost on follow up.Prognosis of PAL was poor. Conclusions PAL is extremely rare with a high grade of malignancy.The diagnosis could be made on histopathological studies and immunohistochemical studies.

Objective To investigate the value of endoscopic ultrasonograghy (EUS) in diagnosis and treatment of gastrointestinal neuroendocrine neoplasm (GI-NEN).Methods We retrospectively summarized the clinical data of 44 patients with GI-NEN which were confirmed by pathology and immunohistochemistry,and analyzed the EUS features and the follow-up data of patients who received EUS exam and EUS-assisted endoscopic resection.Results A total of 47 neoplasms were detected in 44 patients,in which 41 were confirmed as neuroendocrine tumors (NET) and 6 were neuroendocrine carcinoma (NEC).Under EUS,all 41 NET appeared as hypoechoic lesions with regular edge and homogeneous echographic pattern,and 18 were originated from mucosal layer and 23 from submucosal layer,which was all confirmed by pathological evaluation.All 41 NET lesions received EUS-assisted endoscopic resection,in which 17 were treated by ESD/EMR and 24 by high frequency electrotomy.Follow-up endoscopy was performed at 3-6 and 12 month after operation,which showed no residual or recurrence.Conclusion EUS may accurately determine the invasion depth of GI-NEN lesions,and provide important information for adapting appropriate treatment strategies,which has highly clinical practice value in the diagnosis and treatment of GI-NEN.

Objective To investigate the influence of proprioceptive training of hemiplegic stroke patients on their visually compensatory dependence.Methods Twenty stroke patients without vestibular abnormalities were recruited.They were able to walk for 10 meters.All the patients underwent 4 weeks of rehabilitation training including proprioceptive training,treadmill exercises and isometric muscle strengthening.Static standing balance test was performed before and after 4 weeks of treatment.The parameters such as the anteroposterior and mediolateral sway of the center of gravity,center of gravity distribution were analyzed before and after the treatment,taking into consideration of visual feedback (eyes open or closed) by using t-test and multiple linear regression analysis.Results Visual feedback had significant no influence on the anteroposterior sway of center of gravity before and after training (P > 0.05) ; Visual feedback had significant influence on mediolateral sway of center of gravity.Rehabilitation training significantly improved the mediolateral sway in opened-eye standing (P < 0.05) but not closedeye standing (P > 0.05).Visual feedback played significant role in center of gravity distribution after training (P < 0.05).Conclusions Visual compensation is of significant influence on the mediolateral sway.Proprioceptive training can help decrease the patient's dependence on visual feedback and enhance the patient's balance ability.

Objective To compare the feasibility and safety of laparoscopic Roux-en-Y choledochojejunostomy versus open Roux-en-Y choledochojejunostomy.Methods From October 2011 to June 2013,37 patients underwent laparoscopic Roux-en-Y choledochojejunostomy (observation group) and 42 underwent open Roux-en-Y choledochojejunostomy (control group).We retrospectively compare the two groups in terms of operation time,intraoperative blood loss,length of incision,postoperative hospital stay,postoperative gastrointestinal function recovery time,incision infection rate and the incidence of biliary fistula after surgery.Results In observation group operation time was (275.43 t 12.28) min,higher than that of control group (189.12 ± 19.35) min (P =0.031),intraoperative blood loss was (83.13 ±6.34) ml,incision length (5.76 ±0.7) cm,postoperative recovery time of gastrointestinal tract of (43.33 ±3.15) h,postoperative hospital stay (12.65 ± 2.19) d,were in favor of the observation group which were respectively (180.37 ±9.67) ml,(18.51 ±1.9) cm,(70.45 ±4.97) h and (22.16 ±4.61) d (t =33.17,36.73,33.17,P < 0.05).Postoperative incision infection rate in observation group was 5.4%,lower than the control group (19.07%) (chi-square =22.12,P < 0.05).Between the two groups there was no significant difference in the incidence of biliary fistula.Conclusions Laparoscopic Roux-en-Y hepatojejunostomy is safe,effective,and less traumatic procedure.
