ObjectiveTo evaluate the efficacy and safety of domestic taerolimus in the manage-ment of acute rejection in renal transplantation reeipienta.MethodsA multieeneter, open and com-parative study for domestic Taerolimua and Prograf was performed. Eighty reeipienta of first allogenie renal transplantation were randomized into 2 groups: ①Experimental group (accepting Fumeixin ad-ministration, n=58) included 23 males and 35 females with the mean age of(39.1±9.6)years. ②Control group(accepting Prograf administration, n=22) included 12 males and 10 females with the mean age of(41.34±8.5)years. There was no significant difference in the volume, warm and cold is-chemia time of donor renal, age and sex of donor. All of the 80 cases accepted tacrolimus (domestic or foreign made, at the dose of 0. 10～0. 15 mg·kg-1·d-1 , q 12 h) treatment that combined with MMF and prednisone posttransplantation. Tacrolimus CO was aimed to 8-12 ng/ml in the first 60 days and 5-10 ng/ml later. The dose of MMF was according to the rule of each transplantation center based on the following recommendation: 1.5-2.0 g/d for the weight above 70 kg, 1.5 g/d for the weight 50-69 kg, and 1.0 g/d for the weight below 49 kg, in two divided doses. Prednisone was ad- ministrated as per ruler of each center. ResultsObservation termination was 3 months. Morbility of actue rejection was 3.40% (2/58)and 13.6% (3/22) in experimental and control group(P>0.05). Ad-verse events including hypertension, hyperlipemia, hyperglycemia and slight abnormality of liver func-tion occurred in 36. 2%(21/58) and 36. 4% (8/22) cases of experimental and control group(P> 0. 05). The survival rate in the 2 groups was 100%. The dose of tacrolimus in experimental group was significantly lower than that in the control group at 8 and 12 weeks posttransplant, while drug valley concentration in serum was proximal in 2 groups during the whole observation period.Conclusion Domestic tacrolimus capsules can be used effectively and safely in the management of acute rejection in renal transplantation.

Objective:To study the feasibility of extraction of impacted mandibular wisdom teeth using turbine drill and new instruments. Methods: 600 patients with impacted mandibular third molars were divides into 2 groups. A group used turbine drill and new instruments to extract the impacted mandibular third molar. B group used the dental chisel to extract the impacted mandibular third molar. The operation time, intraoperative and postoperative complications were recorded to assess the effects of the methods. Results: The operation time of group A and group B was (22.285±12.025 01) min and (16.115±12.078 62) min respectively. The operation time of group A was shorter(P<0.05). The intraoperative and postoperative complication incidence rate was lower(P<0.05). Conclusion: Turbine drill and new instruments method is superior to dental chisel method in the extraction of impacted mandibular wisdom teeth.

Objective To investigate the effect of umbilical cord blood dendritic cells(DCs)induced by gastric cancer antigen combined with cytokine induced killer(CIK)cells in gastric cancer cell lines SGC-7901 in vitro. Methods Mononuclear cells from umbilical cord blood were used to create DCs and CIKs. The cell surface antigen expression of the mature DCs such as CD83,CD86,CD11c and the cell surface antigen of CIKs such as CD3,CD56,CD4,CD8,CD16 were detected using flow cytometry. Sensitized DCs-CIKs,DCs-CIKs,CIKs as effective cells,and SGC-7901 as target cells,the killing activities of these effective cells were tested with LDH release,which the number ratio of cells between effective cells and SGC-7901 cells were 10 :1,20 : 1,40 : 1,respectively. Results The cell surface antigen expressions of the mature DCs,such as CD83 + CD86 + ,CD11c + CD83 + ,CD86 + CD11c + were(75. 4 ± 2. 1)% ,(79. 3 ± 1. 4)% ,(80. 2 ± 2. 6)% , respectively. The mature sensitive-DCs surface antigen expressions,such as CD83 + CD86 + ,CD11c + CD83 + , CD86 + CD11c + ,were(77. 7 ± 1. 5)% ,(82. 6 ± 1. 9)% ,(76. 9 ± 2. 6)% ,respectively. There was no sta-tistical significance about the surface antigen expression between DCs and sensitive-DCs(t = 1. 526,P ﹥ 0. 05;t = 0. 958,P ﹥ 0. 05;t = 1. 049,P ﹥ 0. 05). The CIKs surface antigen expressions,such as CD4 + ,CD8 + , CD3 + CD56 + CD16 + ,were(22. 8 ± 1. 3)% ,(77. 3 ± 1. 8)% ,(24. 5 ± 2. 1)% ,respectively. The results suggested that the killing effect of the three kinds of combination cells on gastric cancer cells was different. The number ratio of cells between sensitive-DCs and SGC-7901 cells were 10 : 1,20 : 1,40 : 1,which the killing activities of sensitive-DCs-CIKs against SGC-7901 were(37. 68 ± 1. 49)% ,(41. 67 ± 0. 90)% ,(42. 71 ± 0. 98)% ,respectively. The killing activity of sensitive-DCs-CIKs was the highest when the ratio of cells between sensitive-DCs and SGC-7901 cells were 40 : 1. The killing activities of DC-CIKs were(36. 77 ± 0. 46)% ,(38. 94 ± 0. 95)% ,(41. 15 ± 0. 89)% ,respectively. The killing activities of CIKs were(34. 74 ± 1. 01)% ,(37. 76 ± 0. 43)% ,(39. 65 ± 0. 79)% ,respectively. There were statistically significant differences among the three groups(F = 5. 92,P ﹤ 0. 05;F = 19. 13,P ﹤ 0. 05;F = 8. 88,P ﹤ 0. 05). Conclusion The tumor killing activity of CIK is enhanced obviously by umbilical cord blood DCs which is sensitized by gastric cancer tumor antigen. There is the highest killing activity when the number ratio of cells between sensitive-DC-CIK and SGC-7901 cells is 40 : 1.

The changes of bioactive constituents were analyzed for Puhuang-Wulingzhi before and after compatibility and the antiplatelet and antithrombin activitives were evaluated in order to elucidate the scientific and reasonable of Puhuang-Wulingzhi compatibility. UPLC-QTOF-MA-Markerlynx, principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis were used for data analysis and tracking changes of chemical composition during the decocting process. In vitro platelet aggregation induced by ADP, thrombin time(TT) and prothrombin time (PT) were investigated for Puhuang-Wulingzhi before and after compatibility. The results showed that significant differences were found between the mixed decoction and codecoction of Wulingzhi and Puhuang. Five compounds changed obviously were identified as typhaneoside, naringenin, isorhamnetin-3-O-ruinoside, quercetin-3-O-neohesperidoside, kaempferol-3-O-neohesperidoside. The codecoction, comparing with the single decoction, was more significant in antiplatelet aggregation and could prolong thrombin time. In the same crude drug dose, the thrombin time (TT) elongation were greater. These data could provide references for elucidation of bioactive components for this herb pair.

Objective:To explore the relationship between the severity of cardiovascular disease with the expression of apolipoprotein(a) [apo(a)] and apolipoprotein B(apoB) in peripheral blood and their location in peripheral blood cells.Methods: In this report,we selected 4 patients with angiography which indicated that three coronary arteries were narrowed and 5 control patients with normal angiography.Arterial blood was collected and analyzed for lipid parameters in plasma.The mRNA expression of apo(a) and apoB in peripheral white blood cells and platelets were determined by RT-PCR and their protein expression by western blot.Moreover,the expression and location of apo(a) and apoB in white blood cells were determined by confocal microscopy and computer 3D analysis.Results: In plasma,levels of high density lipo-protein-cholesterol(HDL-C) and apolipoprotein A-Ⅰ(apoA-Ⅰ) in cardiovascular disease(CVD) patients were significantly less than those in the control patients[(0.62?0.05) mmol/L,(0.78?0.08) mmol/L vs(0.81?0.15) mmol/L,(0.9?0.07) mmol/L,P0.05).Studies with confocal microscopy indicated that proteins of apo(a) and apoB were co-expressed by a few cells of leukocytes and the ratio of apoB/apo(a) in cardiovascular disease patients was significantly less than that in the control patients(optical density value 1.60?0.12 vs 4.40?0.35,P

Objective: To explore the effects of recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) gel on treatment of thefull-thickness frostbite wounds on foot and hand. Methods: From November 2013 to April 2017, a total of 45 patients of 71 full-thickness frostbite wounds on foot and hand meeting the inclusion criteria were admitted to the First Hospital of Jilin University and the prospective randomized controlled study was done. The patients were divided into rhGM-CSF group of 24 patients with 35 wounds and control group of 21 patients with 36 wounds according to the random number table. There were 20 males and 4 females, aged (38±13) years among patients in rhGM-CSF group, and there were 19 males and 2 females, aged (36±14) years among patients in control group. Patients in 2 groups were performed with the same systemic treatment of rewarming, anti-inflammation, pain relief, anti-infection, anti-coagulation, and thrombolysis. Wounds of patients in rhGM-CSF group and control group were respectively treated with rhGM-CSF gel and aloe vera gel for external usage with 10 mg for every square centimeter and dressing change once every 24 hours, until wounds healed completely. The wound inflammatory response was scored on treatment day (TD) 1, 3, 7, 14, wound secretion was collected for bacteria culture and positive bacteria detection rate was calculated before treatment and on TD 6 and 12, adverse drug reaction after drug use was observed, and the complete wound healing time was recorded. Data were processed with Fisher′s exact probability test, analysis of variance for repeated measurement, t test, and Bonferroni correction. Results: The scores of wound inflammatory response of patients in 2 groups on TD 1 and 3 were close (t=0.37, 2.93, P>0.05). The scores of wound inflammatory response of patients on TD 7 and 14 in rhGM-CSF group were significantly higher than those in control group (t=5.77, 5.83, P<0.01). The results of bacteria culture of wound secretion of patients in 2 groups before treatment were negative. The positive bacteria detection rates of wound secretion of patients in rhGM-CSF group on TD 6 and 12 were 5.71% (2/35) and 22.86% (8/35), which were slightly lower than 13.89% (5/36) and 30.56%(11/36) in control group respectively, but there was no significantly statistical difference (P>0.05). No adverse drug response occurred in patients in rhGM-CSF group, while 1 patient in control group had adverse drug response, with symptoms of redness and swelling of wounds and patchy erythema on skin around wounds, which were alleviated by irrigating with normal saline. The complete wound healing time of patients in rhGM-CSF was (12.3±0.5) d, which was significantly shorter than (16.5±0.8) d in control group (t=24.89, P<0.05). Conclusions The topical rhGM-CSF gel has effects of shortening time of wound healing and reducing inflammatory response of wound on treatment of full-thickness frostbite wounds on foot and hand, which is safe in clinical application.

OBJECTIVETo study the effects of continuous passive motion on the tendon-bone healing of the semi-tendinous tendon autograft used for anterior cruciate ligament (ACL) reconstruction in rabbits.

METHODSIn 12 healthy 8-month-old male rabbits, an ACL reconstruction was performed by using double semi-tendinous tendon autograft. Postoperatively these animals were treated by either continuous passive motion (CPM) or cage activity. Specimens of the grafts were collected at 6, 12, 24 weeks postoperatively. Histological change in the tendon-bone healing was studied by haematoxylin-eosin and toluidine blue.

RESULTSThere was more new fiber tissue in the anterior half of the interface. Osteoclasts were most numerous at the tunnel aperture and in the anterior half of the interface. Cartilage in the tendon-bone interface was localized to the posterior aspect of tunnels, the area where compressive stress would be predicted. CPM group developed a denser connective tissue with less vascularity and cellularity. The bone tunnel had more areas with ingrowing denser connective tissue compared with cage activity specimens. With the growth of Sharpery's fibers and fibrocartilage into the interface, a direct ligament insertion was found. In the CPM specimens, the interface tissue was more mature and the direct insertion was broader and more structured.

CONCLUSIONSCompressive stress promotes chondroid formation, and the tension promotes fiber formation. Tendon-bone healing may be optimized by CPM after tendon transplantation into a bone tunnel.
