Journal of Peking University(Health Sciences) 2003;0(06):-
Objective:To establish an in vitro model for the development of mouse spermatogenic cellsinto sperm by using the immunodefective mouse as the incubator.Methods:Tissue grafting was per-formed using testis from 1-2 days old Kun-ming mice as donor tissue and immunodefective mice as recipi-ents;the expression of TESK1 mRNA in grafts was determined by RT-PCR and the spermatogenesis fur-ther observed with histological analysis of grafts.Results:Molecular biological and histological analysesshowed that grafts post-grafting not only expressed TESK1 mRNA as in normal mouse testis,but also ex-hibited similarities in the structure of seminiferous tubules and component of spermatogenic cells,inclu-ding sperms.Conclusion:Spermatogenic cells heterotopically grafted in vitro could continuously growand complete spermatogenesis and finally develop into sperm.
4.Study on the extraction recovery of docetaxel in plasma by different solid-phase cartridges
Chongqing Medicine 2013;(22):2629-2630,2634
Objective To optimize the solid-phase extraction method by comparison of the extraction recovery of docetaxel plas-ma samples.Methods After extracted by different solid-phase cartridges with water,acetonitrile,and different content methanol e-lution,the plasma samples were analyzed on an Phenomenex LUNA C18 column(4.6 mm×250 mm,5μm)with mehhanol:acetoni-trile:water(42∶26∶32,v/v/v)as the mobile phase.From the recovery achieved,the best solid phase cartridge was found.Results This method consists of using 60%-80% methanol for the elution.Among the three kinds of solid-phase being tested,Waters Oasis HLB cartridge was found to be the best one.Conclusion The average extraction recovery of the Waters Oasis HLB cartrid-ges was between 95%-105%,and it can be used in the analysis of docetaxel in plasma samples.
6.Study on Role of Non-coding RNA in Barrett's Esophagus
Chinese Journal of Gastroenterology 2017;22(7):429-431
Non-coding RNA (ncRNA) is a class of RNA not coding the protein and plays a significant role in the process of growth and development of diseases.Barrett''s esophagus (BE) is considered as the precancerous lesion of esophageal adenocarcinoma.Several studies showed that ncRNA has the potential value in diagnosis, treatment and designing of targeting drugs.This article reviewed the role of ncRNA, especially microRNA, long non-coding RNA and circular RNA in the development and carcinogenic process of BE.
7.Clinical observation of auricular acupoint therapy for pain in early-stage extremity trauma
Journal of Acupuncture and Tuina Science 2017;15(3):219-222
Objective:To observe the efficacy of auricular acupoint sticking based on conventional treatment in treating pain in early-stage extremity trauma.Methods:A hundred eligible patients with acute soft tissue injury or acute closed fracture were randomized into an observation group and a control group by their admission sequence, 50 cases in each group. The two groups both received routine management including routine checking, external fixing, traction, raising up the affected limb, etc., as well as cold compress with Chinese medication (Xiao Zhong Zhi Tong Powder). In addition to the routine management, the control group was given oral administration of amidopyrine and phenacetin compound tablet, 1 tablet per dose, twice a day, which was then taken only when necessary or terminated after pain subsided. The observation group was given auricular acupoint sticking in addition to the routine management. The two groups were compared in terms of numerical rating scale (NRS) score, therapeutic efficacy and adverse reactions after pain was relieved.Results:After the intervention, the NRS scores dropped significantly in both groups (P<0.01); the NRS score in the observation group was significantly lower than that in the control group (P<0.05).The total effective rate in the observation group was superior to that in the control group (P<0.05).There were no severe adverse reactions in the two groups.Conclusion:Based on routine management, auricular acupoint sticking can produce a more significant efficacy in treating pain in early-stage extremity trauma compared to amidopyrine and phenacetin compound tablet; it can effectively reduce pain of the affected limb and prevent complications; it's easy-to-operate and safe; patients can learn and understand it easily; its efficacy is confirmed; it enhances the satisfaction degree of the inpatients. Therefore, this method is worth promoting in clinic.

International Journal of Surgery 2016;43(12):817-820,封3
Objective To comparatively complete clinical effectiveness of laparoscopic and open-bifemoral bypass in the treatment of advanced atherosclerosis.Methods During January 2008 to January 2013,according to the treatment method,a total of 60 patients with advanced atherosclerosis patients were divided into group A and group B,and there were 30 cases in each group,and group A was treated with open master bifemoral bypass surgery,and group B was treated with laparoscopic totally master bifemoral bypass surgery,to compare the general information of the two groups,surgery related indicators,clinical efficacy and survival rate,and to analyze the effect of surgical treatment on the prognosis of patients by COX model.Results The operation time of patients in group B (365.3 ±41.3) min and aortic clamping time (59.5 ± 18.3) min were significantly higher than that of group A,(294.3 ±35.5) min and(26.5 ± 19.3) min (P <0.05),bleeding amount (400.0 ± 145.3) ml and length of hospital stay (10.5 ± 2.1) d of group B patients was significantly lower than that of group A (1 002.3 ± 324.3) ml and (16.4 ± 4.3) d (P < 0.05);postoperative mortality,thrombosis rate and the incidence of serious complications of patients in group B were significantly lower than group A (P < 0.05);survival rate at different time of group B was significantly higher than that of group A (P < 0.05);COX model analysis show that the surgical methods affect the postoperative mortality,thrombosis and the occurrence of severe complications.Conclusions Completely laparoscopic master bifemoral bypass can significantly decreased advanced main iliac artery occlusion disease mortality,and has small surgical trauma,less postoperative complications,rapid recovery and other advantages,especially for elderly critically ill patients,and it was worthy of clinical application.

10.The Influences of Immune Suspression by Oral Administration of Type Ⅱ Collagen on Rat Rheumatic Osteoarthritis and Traumatic Osteoarthritis
Chinese Journal of Sports Medicine 1982;0(01):-
Purpose: To study the influences of immune suspression by oral administration of type Ⅱ collagen on the pathogenesis of collagen induced arthritis(CIA) and traumatic oseoarthritis(OA) in rats; Methods: Rat knee traumatic osteoarthritis model made by excision of medial collateral ligament and medial meniscetomy and CIA model were applied for the observation of the changes on hisological and histochemical staining and the inhibition of T cells after oral administration of type Ⅱ collagen. Results: In OA, although the T cells were suspressed by oral administration of type Ⅱ collagen, however, the the pathogenesis was not hindered comparing with RA. It indicated that for OA, machanical factor is more important than the immunological factor, oral administration of type Ⅱ collagen has little effect on decreasing the speed of development of OA. It is not adequate to take the remedy of oral administation of type Ⅱ collagen for the treatment of OA.
