ABSTRACT
Objective@#To evaluate the efficacy and safety of a domestic human plasma derived coagulation Factor Ⅸ concentrate (pd-FⅨ) in patients with hemophilia B.@*Methods@#The study was a multicenter, open-label and single-arm study. The efficacy of pd-F Ⅸ was evaluated by objective performance criteria. The doses of pd-FⅨ were calculated according to the bleeding symptom and disease severity. The infusion efficiency of pd-FⅨ and improvement of bleeding symptoms were measured at 30 minutes and (24±4) h after the first infusion, respectively. Adverse events were recorded. Viral infection and FⅨ inhibitor were detected 90 d after the first infusion.@*Results@#All 36 subjects with hemophilia B were enrolled in the study. The median age of these patients was 31 years old and the median injection doses were 4 (1-17) times. The hemostatic effect of 27/36 (75.00%) and 9/36 (25.00%) acute bleeding events were rated as "excellent" and "better" , respectively. The recovery rate was 111.92% (65.55%-194.28%) at 30 minutes after infusion of FⅨ. There was no adverse event related to FⅨ. No reactivation of HBV, HCV or HIV and FⅨ inhibitor was detected at 90-104 d after the first FⅨ infusion.@*Conclusion@#This domestically made human plasma derived FⅨ concentrate is safe and effective in the treatment of acute bleeding in patients with hemophilia B.@*Clinical trial registration@#China food and Durg Administration, 2016L08027.
ABSTRACT
This article reported jaw osteomyelitis in ancient human bone specimens, helping us to understand the emergence of ancient human jaw osteomyelitis and other oral health conditions.
ABSTRACT
OBJECTIVE:To investigate the improvement effects of Zhuanggushenjin capsules on osteoporosis induced by reti-noic acid in mice. METHODS:84 mice were randomly divided into normal control group,model control group,positive control group [Gushukang granules,5 g(crude drug)/kg] and Zhuanggushenjin capsules high-dose,medium-dose and low-dose groups [7.80,3.90,1.95 g(crude drug)/kg]. Except for normal control group,those groups were given retinoic acid(90 mg/kg)to induce osteoporosis model. 7 days after modeling,all drug groups were given relevant medicine intragastrically,normal control group and model control group given normal saline intragastrically ,once a day,for consecutive 14 days. ALP activity and the contents of cal-cium and phosphorus in serum and thigh-bone were determined. The body weight, the dry weight, length and diameter of thigh-bone were determined,and organ coefficients (spleen,testicle,ovarium and uterus) were calculated. RESULTS:Compared with normal control group,the activity of ALP in serum of mice increased in model control group,while the contents of calcium and phosphorus,body weight,length and diameter of thigh-bone decreased significantly;spleen coefficients increased,while testi-cle and uterus coefficients decreased(P<0.05 or P<0.01). Compared with model control group,the contents of calcium and phos-phorus increased in Zhuanggushenjin capsules groups,while spleen coefficient decreased;the activity of ALP in serum of mice de-creased in high-dose and medium-dose groups,while body weight,the length of thigh-bone,testicle and uterus coefficients in-creased;diameter of thigh-bone increased in high-dose group (P<0.05 or P<0.01). CONCLUSIONS:Zhuanggushenjin capsules can improve retinoic acid-induced osteoporosis in mice to certain extent.
