[Objective]To introduce the knowledge for the diagnosis of acute gout arthritis that attacked initially in the knee and improve its early treatment.[Method]Seventeen cases with acute gout arthritis in the knee were diagnosed and treated under arthroscopy since 2000.The experiences were analysed retrospectively and the therapatic results were observed through a follow-up of more than 6 months.[Result]Before arthroscopy,only 5 cases were considered as acute gout arthritis,the other 12 cases were given a misdiagnosis.All the patients were diagnosed and given a debridment simutaneously under arthoscopy.Then,the patients were given an postoperative systematic drugs therapy.The follow-up(ranged from 10 to 24 months)showed that all the patients acquired a short-term and long-term satisfactory therapeutic effect.[Conclusion]The acute gout arthritis attacked initially in the knee is rare and its misdiagnosis rate is very high.The significant improvement and extensive application of arthroscopic techniques will improve its diagnosis rate and provide a new way for its early surgical treatment.

Objective To study the therapeutic effect and mechanism of IL-6 reduced by the early shortlime veno-venous hemodialysis (BVVH) for the treatmnent of severe acute pancreatitis (SAP).Method One hundred and seventy-eight cases with SAP,in depagtment of general surgery,the Third People Hospital,Shanghai Jiao Tong University School of Medicine,were divided inlo hemodialysis group (HF,85 cases) and non-hemodialysis group (NHF,93 cases).The local and systemic manifestations,APACHE Ⅱ scores,average hospitalizing stay,mean cost of therapy,morbidity of MODS and the mortality of patients were compared between two groups.And the concentration of serum inflammatory factor IL-6 was assayed at different observation intervals.All data were managed by SPSS software and analyzed by using SNK-q test or X2 test.Results The duration for abdominal pain and distension in patiergs of HF group was (18.8+=4.2) h vs.(89.7±28.1) h in those of NHF group,P<0.05.The APACHE Ⅱ scores at the 10th day were (5.5±3.6) vs.(13.8±3.8) (P<0.05).The average hospitalizing stay and the mean costs of medical care were (28.2+ 12.4) d vs.(42.4+11.2) d and (43800±28000) vs.(74600±22000) RMB(P<0.05) respectively.The concontrafion of serum inflammatory factor IL-6 in HF group decreased significantly(P<0.05) in comparison with those in NHF group.And the morbidity such as MODS and the mortality in HF group were significantly less than those in NHF group(P<0.05).Conclusions By BWH,the excessive release of serum inflammatory factor IL-6 could he removed at early stage of SAP.So,it could result in an improving on the severity of the disease and raise the therapeutic efficacy.

OBJECTIVE:To investigate the compatibility stability of Salvianolic acid for injection (SAFI) combined with 8 kinds of common solvents. METHODS:Referring to package inserts,SAFI was collected and combined with 0.9% Sodium chlo-ride injection,5% Glucose injection,10% Glucose injection,Compound sodium chloride injection,Mannitol injection,Glycerol fructose and sodium chloride injection,Sodium lactate Ringer's injection,Glucose and sodium chloride injection,250 mL each re-spectively,and then sealed in the dark at the room temperature. The appearance of mixtures were observed,pH value,the number of insoluble particles,maximal absorption wavelength and maximal absorbance were detected,and the contents of salvianolic acid B,rosmarinic acid,lithospermic acid and salvianolic acid Y in mixtures were determined by HPLC at 0,1,2,4,8 h after mix-ing. RESULTS:Under above condition,no obvious change was found in appearance or pH values of the mixtures within 8 h. Maxi-mal absorption wavelength ranged 284.5-286.0 nm. After mixed with Mannitol injection,the number of particles≥10μm(1-8 h af-ter mixing)and particles ≥25 μm(4-8 h after mixing)exceeded the scope of Chinese Pharmacopoeia(2015 edition);the maxi-mal absorbance changed significantly(RSD=9.17%,n=5);the relative content of salvianolic acid B,rosmarinic acid,lithosper-mic acid and salvianolic acid Y decreased by more than 10%(RSD=14.65%,6.45%,8.97%,12.49%,n=5);after mixed with Sodium lactate Ringer's injection,the relative content of rosmarinic acid and lithospermic acid changed greatly (RSD=14.57%, 7.28%,n=5);after mixed with 5% Glucose injection(4-8 h after mixing)and Glycerol fructose and sodium chloride injection(8 h after mixing),the relative content of rosmarinic acid were less than 90%(RSD=6.30%,4.86%,n=5);and the number of particles ≥25μm exceeded the scope of phamcopoeia after mixing with Glycerol fructose and sodium injection(0 h). The number of insoluble particles in other mixtures were in line with the standard of pharmacopoeia;maximal absorbance had no significant change(RSD<5%,n=5),and the relative content change of analytes were all less than 10%. CONCLUSIONS:Clinical appli-cation of SAFI combined with Mannitol injection,Sodium lactate Ringe's injection and Glycerol fructose and sodium injecrion should be avoided. After mixed with 5% Glucose injection,SAFI should be used within 4 h. SAFI can be compatible with 0.9%Sodium chloride injection,10% Glucose injection,Compound sodium chloride injection and Glucose and sodium chloride injec-tion.

BACKGROUND: Ultra-high molecular weight polyethylene (UHMWPE) is widely used as acetabulum. The hip joint will produce lots of grind particles and lead to loosening of artificial joint because of alternating load and bad lubricate condition.OBJECTIVE: To learn about the lubricate mechanism of joint, introduce the present situation on artificial hip joint of UHMWPE including wear behavior and wear resistance properties, and grope for scientific evaluate method of tribological properties in artificial joints.RETRIEVAL STRATEGY: The articles published between January 2000 and October 2007 were searched by using computer with the key terms "hip joint, ultra-high molecular weight polyethylene, tribology" in CNKI, Weipu Science and Technology Database, Wanfang Database, and its language was limited to Chinese. Meanwhile, the English articles were searched in IEEE/IEE Electronic Library and Elsevier Electronic Journal Database with the key terms "hip simulators, ultra-high molecular weight polyethylene, tribology ". Those referring to the friction and wear property of the joints were included, whereas repeated researches were deleted.LITERATURE EVALUATION: Totally 729 articles were received. After the primary screening of the titles and abstracts, 601 repeated or similar researches were excluded, and other 128 articles were adopted for further analysis, finally 22 articles in accordance with the inclusion criteria were included as references.DATA SYNTHESIS: The study about UHMWPE focused two points, one is surface modification, the other is wear and friction mechanism.①The study indicates that wear properties of UHMWPE can be improved by surface modification, such as ion implantation and nanometer padding have a remarkable elevating ability of the wear and mechanical properties.②At recent years, scholars do many basal experiences about the tribology of hip joints, and have approved that wear rate of friction pairs would reduce under biological lubricate condition using artificial joint simulators or traditional tester in various conditions.CONCLUSION: The study about hip joint in China drops behind the developed counties, this traditional method can not really reflect wear and friction properties in vivo. Therefore, the following research should include making clear the relationships of load, environmental condition and wear of artificial joint in vivo, as well as groping for a scientific evaluate method of tribological properties in hip joints.
