ABSTRACT
Hemophagocytic syndrome (HPS), which is currently named as hemophagocytic lymphohistiocytosis (HLH), is a hyperinflammatory syndrome characterized by persistent fever, hepatosplenomegaly, pancytopenia and hemophagocytosis found in bone marrow, liver, spleen and lymph nodes due to excessive activation of macrophages and cytotoxic T cells. Macrophage activation syndrome (MAS) is a specific form of HLH induced by autoinflammatory/autoimmune disorders which can be life-threatening and requires multiple disciplines. In order to improve clinicians′ understanding of MAS and standardize the clinical diagnosis and treatment practice of MAS, the rheumatology branch of Chinese Rheumatology Association organized domestic experts to formulate the diagnosis and treatment standard, in order to improve the diagnosis and treatment level of MAS and improve the prognosis of patients.
ABSTRACT
Objective To establish the quality standards for salt eucommia dispensing granules. Methods The extractives were obtained by alcohol extraction method. HPLC was applied for the determination of pinoresinol diglucoside in dispensing granules. HPLC fingerprints were established by the contrast of Agilent 1260 HPLC, Waters HPLC and various chromatogram column. Results Pinoresinol diglucoside showed a good linear relationship ( Y = 2. 9594X + 3. 2825,R2 =0.9999) at 102.8-2056.0 mg?L-1 with average recovery of 99.85％ (RSD = 0.31％,n = 9). Conclusion The method is easy-operated and accurate,which has a good specificity for the quality control of common salt eucommia dispensing granules.
ABSTRACT
Objective To explore the relationship between gout and its comorbidities such as hypertension,diabetes and dyslipidaemia.Methods The clinical data in 187 cases of gout admitted in the Third Affiliated Hospital of the Third Military Medical University from June 2013 to December 2015 were retrospectively analyzed.The patients were grouped according to the disease course,with or without tophi and nephrolithiasis.Then the relationship between gout and its comorbidities was investigated.Results The most common comorbidity of gout was dyslipidaemia (51.45％),followed by hypertension (46.52％),osteoarthritis (43.09 ％),fatty liver(42.19 ％),kidney stone (35.90 ％),renal dysfunction (23.53 ％) and diabetes (16.58 ％).The patients with longer disease duration(≥ 10 years) were more likely to suffer higher prevalence of tophi,renal dysfunction,hypertension and osteoarthritis.Furthermore,the patients with tophi demonstrated remarkably higher levels of serum uric acid and greater prevalence of renal dysfunction and osteoarthritis than those without tophi.In addition,the prevalence rate of comorbidities had no difference between the patients with and without kidney stones.Conclusion The patients with gout have higher morbidity rate of comorbidities.Gout patients with younger onset age,longer disease duration,older age or tophi are more likely to present with comorbidities.
ABSTRACT
Objective:To explore the association between rheumatoid arthritis(RA)and two polymorphisms of interleukin-17(IL-17F)rs763780 and rs2397084.Methods: A systematic search of relevant studies was conducted in China National Knowledge Infrastructure,Wanfang Chinese Periodical Database,China Biology Medical Literature Database,Pubmed,Embase and Web of Science.Results: A total of 5 case-control studies including 1 174 RA cases and 966 health controls for rs763780 and 985 RA cases and 766 health controls for rs2397084 were included in this Meta-analysis.The results showed that rs763780 was significantly associated with increased susceptibility to RA(C vs.T:OR=1.74,95%CI=1.01-2.98,P=0.04;CC vs.TT:OR=3.17,95%CI=1.21-8.35,P=0.02;CT vs.TT:OR=1.80,95%CI=1.21-2.66,P=0.004;CC+CT vs.TT:OR=1.96,95%CI=1.35-2.83,P<0.001;CC vs.CT+ TT:OR=2.97,95%CI=1.13-2.66,P=0.03).In subgroup analysis based on ethnicity,rs763780 was positively correlated with RA in Europeans.No significant association was found between rs2397084 and RA.Conclusion: The present study revealed that IL-17F rs763780 polymorphism is a risk factor of RA,while the association of rs2397084 with RA remains uncertain.
ABSTRACT
The PBL was adopted by the author in training medic in the department of digestion.The method has shown that it can improve the capability of independent study,spirit of team cooperation,clinical practice ability and improve comprehensive qualities.In the meanwhile,it can improve the tutor's all-around caliber.To guarantee the teaching effect,the tutor should especially comprehend the theory and skills of PBL,to design masterly clinical questions,to ensure the practice time and assistant facilities thoroughly.
ABSTRACT
Objective To establish an experimental model of HCV C-HBV X coexpression protein and explore its effect on tolemerase activity. Methods The HBV X gene was recovered by enzyme digestion, cloned into PBK-CMV and PBK-HCV C, and the recombinant plasmids PBK-X and PBK-X-C were obstained. The plasmids PBK-CMV, PBK-X, PBK-HCV C and PBK-X-C were transfected into HepG2 cells with liposome. After selected with G418, positive colonies were obtained. The reverse transcription PCR and Western blotting were used to detect HBV X and HCV core protein expression and PCR-ELISA for tolemerase activity. Results The recombinant plasmid PBK-X-C could express HBV X and HCV core protein efficiently. The telomerase activity of the cells coexpressed HCV C-HBV X protein was higher than that of cells expessed HBV X, HCV C and vector only. Conclusion HBV X-HCV C coexpression protein can increase the telomerase activity of HepG2 cells, which suggests that HBV and HCV can cooperate with carcinogenesis.
ABSTRACT
The effects of intramuscular or intracerebroventricular injection of penta-gastrin(PG) on the action potential amplitude (APA) of the myocardial cells and the heart rate(HR) were studied. The results were as follows:1 ) Injection of 10?g/10?l of PG into one of the lateral ventricles of the ratfailed to produce any effect on APA or HR. When the dosage of PG was doubled(20?g/10?l), then HR could be slowed down significantly (P
