Total hip arthroplasty (THA) is a vital therapeutic tool for hip terminal disease. Frequently, hidden blood loss exists in the postoperation, which seriously affect the postoperative rehabilitation of patients. It is urgent need to solve the problem that how to fundamentally prevent and reduce hidden blood loss after THA. Although THA has its own operational reason in blood loss, and also relates to a variety of risk factors, the mechanism of hidden blood loss is not clear. Tranexamic acid has a significant role in preventing perioperative blood loss, and the correlation of hidden blood loss and fibrinolytic mechanism would be confirm necessarily in the future,which will produce positive significance in completing the mechanism of hidden blood loss.

BACKGROUND: High oxalic acid urine is a risk factor for stone formation. Constructing cel lines with high oxalate metabolic ability using genetic engineering and stem cel technology wil become the effective method to prevent and treat calcium oxalate stone. OBJECTIVE: To construct the adult bone marrow mesenchymal stem cel lines that can decompose the oxalic acid, through co-transfecting the oxalic acid degradation genes Frc and Oxc of oxalobacter formigenes into the normal adult bone marrow mesenchymal stem cells. METHODS: Frc and Oxc were amplified by PCR, and the eukaryotic expression vectors of pLEGFP-N1-myc-Frc and pBaBE-puro-flag-Oxc were constructed, then co-transfected into the normal adult bone marrow mesenchymal stem cells. The non-transfected bone marrow mesenchymal stem cells and the cells transfected with empty vectors were as control. Western blot was performed to detect the expression of the objective genes;the concentration of oxalate in the culture medium after transgenic was determined by ion chromatography. RESULTS AND CONCLUSION: Restriction enzyme digestion and sequencing results showed that the Frc and Oxc genes were successful y amplified, and the vectors of pLEGFP-N1-myc-Frc and pBaBE-puro-flag-Oxc were constructed. After tranfected into the bone marrow mesenchymal stem cells, the Western blot results showed that transfected bone marrow mesenchymal stem cells could stably express the target protein myc-formyl coenzyme A transferase enzyme and the flag-oxalyl coenzyme A decarboxylase; ion chromatography test results showed with the prolonging of the culture time, the concentration of oxalic acid in the human bone marrow mesenchymal stem cel culture medium transfected with target gene was decreased gradual y. While there was no target protein expression in the non-transfected human bone marrow mesenchymal stem cells as wel as the cells transfected with empty vectors. The cells had the ability of oxalate-degradation. The experiment successful y constructs the adult bone marrow mesenchymal stem cel lines that can decompose the oxalic acid, and the cel lines have the ability of oxalate-degradation and can stably express the oxalate decomposition proteins Frc and Oxc.

Objective To observe the changes of lung parameters,the ratios of B and T lymphocyte attenuator(BTLA) and serum cytokines in patients with knee osteoarthritis (KOA),and explore possible molecular mechanism of them.Methods Forty-seven cases of knee osteoarthritis from the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from 2011 October to 2012 July were analyzed in this study.Pulmonary parameters were detected by spirometer; B and T lymphocyte attenuator(BTLA) was detected by flow cytometry ; Interleukin (IL)-1β,IL-10,matrix metalloproteinase-9 (MMP-9),tissue inhibitor of matrix metalloprotease-1 (TIMP-1) were detected by ELISA;ESR was determined by Westergren method ; hs-CRP was determined by the automatic biochemistry analyzer.Results (1) Compared with NC group,levels of FVC,FEV1,FEV1/FVC,PEF,MEF25.75,MEF50,MEF25,CD3 + BTLA+ T cell,CD4+ BTLA+ Tcell,IL-10,TIMP1 were significantly decreased,IL-1 β,MMP9 were significantly increased.(2)Correlation analysis showed FVC was negatively correlated to Lequesne MG,symptom classify quantization scores,course,MMP9,while positively related to CD3+ BTLA+T cell,IL-10,TIMP1 ;FEV1 was positively correlated to CD3 + BTLA+T cell,CD4+ BTLA+T cell,TIMP1,while negatively correlated to course ; MEF50 was positively related to CD3+BTLA+T cell,CD4+ BTLA+T cell.Conclusion While articular cartilage lesions occurred in KOA patients,the lung function was also declined.The mechanism may be associated with the declination of expression of BTLA,which can cause up-regulating of IL-1 β,MMP9 and down-regulating of IL-10,TIMP1,thus leading to immune dysfunction and abnormal immune response.Those may induce airway injuries and result in lung function decline finally.

AIM: To compare the contents of baicalin,paeoniflorin and glycyrrhetic acid in the seperated and mixed decoction of Huangqin Decoction(Radix Scutellariae,Radix Paeoniae alba,Radix et Rhizoma Glycyrrhizae and Fructus Jujubae). METHODS: The contents of baicalin,paeoniflorin and glycyrrhetic acid were analyzed by HPLC.Chromatographic conditions included: Hypersil BDS C_(18) column and the mobile phase consisted of a mixture of methanol-water-phosphoric acid(47(∶)53(∶)0.2),acetonitrile-water-phosphoric acid(18(∶)82(∶)0.1) and methanol-water-phosphate buffer solution(70(∶)29(∶)1).Baicalin,paeoniflorin and glycyrrhetic acid were detected at 280 nm,230 nm and 250 nm respectively. RESULTS: The linear range of baicalin,paeoniflorin and glycyrrhetic acid were 2.88—72.00 ?g/mL,2.85—22.80 ?g/mL and 4.16—52.00 ?g/mL respectively.The contents of baicalin in the mixed decoction was higher than that in the seperated decoction.The contents of paeoniflorin and glycyrrhetic acid in the mixed decoction were almost as same as that in seperated decoction. CONCLUSION: The contents of active ingredients in the mixed and seperated decoction are different.

OBJECTIVETo explore the effect of Xinfeng Capsule (XC) on lipoprotein metabolism of rheumatoid arthritis (RA) patients.

METHODSTotally 180 RA patients were assigned to the experimental group and the control group by random digit table, 90 in each group. Patients in the experimental group took XC (three pills each time, three times daily), while those in the control group took Methotrexate Tablet (four tablets each time, once per week). One month consisted of one therapeutic course and all patients were treated for two therapeutic courses. A healthy control group consisting of 60 patients was also set up. Changes of lipoprotein indices, clinical efficacy, lipid metabolism, joint symptoms and signs, activity indicators were observed, and correlation analyses were performed.

RESULTSCompared with the healthy control group, expression levels of prealbumin (PA), globulin (GLO), high-density lipoprotein (HDL), apolipoprotein Al (Apo-A1) were lowered in RA patients (P <0. 05, P <0. 01). Correlation analyses showed that PA was negatively correlated with joint tenderness, morning stiffness time, disease activity score (DAS-28), C-reactive protein (CRP), interleukin (IL)-6, respectively. Total protein (TP) was negatively correlated with joint tenderness. GLO was negatively correlated with joint tenderness and DAS-28. HDL was negatively correlated with erythrocyte sedimentation rate (ESR) and endothelin (ET)-1. Apo-Al was negatively correlated with joint pain; Apo-B was negatively correlated with CRP; LDL was negatively correlated with morning stiffness time (P <0. 05, P <0. 01). Compared with before treatment, expression levels of PA, HDL, Apo-A1 , Apo-B, and serum IL-10 contents increased, and expression levels of ESR, CRP, IL-6, ET-1 , joint pain, joint swelling, morning stiffness time, and DAS-28 decreased in the experimental group (P <0. 05, P <0. 01). PA increased more after treatment than before treatment in the control group (P <0. 01). There was statistical difference in joint symptoms (except joint tenderness) and activity indices (except ET-1) in the control group (P <0. 05, P <0. 01). Compared with the control group after treatment, PA and HDL increased, ET-1 and duration of morning stiffness decreased in the experimental group (all P <0. 05).

CONCLUSIONSLipoprotein metabolic disorder exists in RA patients, and it is associated with disease activity. XC could obviously improve lipoprotein metabolism and joint symptoms.
