Objective To study the possible mechanism of Bushenqiangdu recipe in treatment of ankylosing spondylitis(AS). Methods 30 out-patients were treated by Bushenqiangdu recipe for 6 months. The expression level of IL-18,IFN-?,IL-4 mRNA in outer-circumference blood of as patients and healthy volunteers were studied,as well as the change expression level of IL-18,IFN-?,IL-4 mRNA of as patients outer-circumference blood before and after treatment. Result The expression level of IL-18,IFN-?mRNA in AS patients PBMC group is higher prominently than control PBMC group(P

Objective To evaluate the clinical efficacy and safety of ranibizumab in the treatment of corneal neovascularization(CNV)in elderly patients.Methods A total of 40 elderly patients(50 eyes)with conceal neovascularization were enrolled in this study at our hospital.Among them,20 patients(22 eyes)in observation group enrolled from January 2015 to December 2015,received subconjunctival injection of ranibizumab,and 20 patients(28 eyes)in control group enrolled from June 2014 to December 2014,receivedlaser photocoagulation.The visual acuity,the area of corneal neovascularization,intraocular pressure and therapeutic response rate were measured and compared between two groups before and 1 month,6 months and 12 months after treatment.All patients were followed up for 12 months to record the recurrence and complications.Results In the observation group,20 eyes(90.9％),19 eyes(86.3 ％)and 19 eyes(86.3％)got an improved eyesight at 1 month,6 months and 12 months of ranibizumab treatment,respectively,which were significantly higher than those in the control group(16/57.1％,14/50.0％,12/42.9％,x2 =6.910,5.866,8.010;P=0.031,0.020,0.016,respectively).The area of corneal neovascularization was decreased in both groups after treatment in the comparison of pretreatment.What is more important:at 1 month,6 months and 12 months of treatment,the areas of CNV were all significantly smaller in the observation group than in the control group (t =6.109,5.291,8.330;P =0.019,0.033,0.009,respectively).There was no significant difference in intraocular pressure before versus after treatment in both groups(both P＞ 0.05).The therapeutic response rate was 90.9% (20/22)in observation group,and 75.0% (21/28)in control group(x2 =6.109,P =0.006).During the 12-month follow-up after operation,the recurrence rate of CNV was significantly higher in control group(7 eyes,25.0％)than in observation group(2 eyes,9.1%) (x2 =8.668,P =0.003).Conclusions Subconjunctival injection of ranibizumab is effective and safe with a fewer complications in the treatment of corneal neovascularization in elderly patients,which is worthy of generalizing in clinical treatments.

【Objective】 To investigate the management of adverse reactions to blood donation(ARBD) in blood services, so as to promote the surveillance of ARBD and improve the quality of blood donation service in Chongqing. 【Methods】 A questionnaire, involving the staff and facilities in blood donation sites as well as the prevention and treatment, the record and report, the following up and data related to ARBD was developed by Chongqing Society of Blood Transfusion in February 2019, and was issued to 18 blood services(1 blood center and its sub-center, 6 central blood stations and 11 hospital blood banks) in the Chongqing via email. The questionnaire was filled in and submitted before March 31 by management personnel participating in the investigation, and the data was collected, collated, revised and analyzed by Excel 2011. 【Results】 A total 19 questionnaires were collected, with the valid rate at 100%(19/19). 78.95%(15/19) of the blood services met the requirements of medical personnel allocation(>6 medical staff) when the number of daily blood collection was more than 60, and 100%(19/19)met the requirements of medical personnel allocation(2 to 6 medical staff) when the number of daily blood collection was less than 60. 89.47%(17/19) of the blood services were equipped with epinephrine hydrochloride, and 84.21%(16/19) with dexamethasone(an anti-allergic drug). There were significant differences in the allocation of other types of drugs. 100.00%(19/19) of the blood services formulated prevention and treatment measures concerning ARBD. In 2019, the incidence of ARBD in Chongqing was reported to be 0.54%(1 958 / 359 871), with the highestas [1.35%(223/16 543)] in subcenters and the lowest [0.32%(179/56 299)] in central blood centers (P<0.05). There was statistical significances in the incidences of ARBD reported by different blood stations(P<0.05). 【Conclusion】 The monitoring and management of ARBD among blood services in Chongqing should be further standardized in terms of staffing allocation, emergency drugs allocation and reporting, so as to gradually realize regional homogenization and ensure blood safety.

Objective: To evaluate the efficacy of dynamic locking screw combined with plate internal fixation for tibial fractures. Methods: A retrospective case-control study was conducted to analyze the clinical data of 36 patients with tibial fractures (AO 4A-C) admitted to the Second Affiliated Hospital of Army Medical University from March 2017 to March 2018. There were 27 males and nine females, aged 26-71 years [(51.6±14.3)years]. A total of 18 patients were treated with dynamic locking screw combined with locking plate internal fixation (Group A), and another 18 patients received common locking screw combined with locking plate internal fixation (Group B). The operation time, intraoperative bleeding, hospital stay, visual analogue score (VAS), callus growth and fracture healing rate at 4, 8, 12 and 24 weeks after operation were compared between the two groups. At the same time, the complications of internal fixation were evaluated, including screw loosening, screw fracture and steel plate fracture. Results: All the patients were followed up for 8-18 months [(12.2±2.7)months]. There was no significant difference in operation time, intraoperative bleeding, postoperative hospital stay and postoperative VAS between the two groups (P>0.05). At 8 and 12 weeks after operation, the callus growth rate of Group A was 61% and 83% respectively, significantly higher than those of Group B (28% and 50%) (P<0.05). At 8, 12, and 24 weeks after operation, the fracture healing rate of Group A was 17%, 50% and 100% respectively, and those of Group B was 6%, 28% and 89%, showing no significant difference between the two groups (P>0.05). No complications or failure of internal fixation were found during the follow-up. Conclusion For tibial fractures, the locking plate internal fixation can achieve satisfactory clinical outcome, but the dynamic locking screw system can promote the growth of callus at early stage.
