Objective Study on the traceability of serum enzyme ass ays by testing enzyme reference material in clinical laboratories. Methods 50 laboratories were involved in this survey. One enzyme reference material was send to each participate lab. The reference material was tested by use of routine method and the results were recorded. All lab data were processed with computer. Results Compare with the target values, the bias of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK) and lactate dehydrogenase (LD) assays were 6 3%, 5 5%, -5 9% and -5 0% respectively, the bias of alkaline phosphatase (ALP) assays was -36 6. The inter laboratory coefficient variation of the amylase assay was 29 2%. Conclusions The results of enzyme assay in clinical laboratories could be traced to the international reference material.

Though there are different kinds of view on diabetic nutritional therapy for a long time,it is the basic treatment method on diabetes mellitus(DM).With some result of clinical research on diabetic nutritional therapy,people knew it more and more.To discuss new diabetic nutritional therapy is of great benefit to improve the curative effect and prolong the syndrome of DM.

Objective: To observe the short-term curative effect of radiofrequency ablation with active electrode cooling in the treatment of hepatocarcinoma. Methods: Radiofrequency ablation therapy was targeted to 117 tumor bodies of 43 patients with hepatocarcinoma using cooled-tip radiofrequency energy delivery machine (HG-3000). The change of tumor size was observed using CT and type B ultrasonic examination. The level of alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), the liver function were recorded and compared with pretreatment. Results: Radiofrequency ablation therapy significantly inhibited the growth of 117 tumor bodies. The AFP value obviously decreased compared with pretreatment (P<0.05); the CEA value had the tendency to continually increase. The CEA value had significant difference after 3-, 4-, and 5-month therapy compared with pretreatment (P<0.05). The liver function had obvious changes after 1- or 2-week therapy and recovered to the primary value before treatment after 4 to 5 weeks. Conclusion: The radiofrequency ablation with active electrode cooling may achieve satisfactory efficacy and has little complications.

Objective To evaluate the bactericidal effect of diode laser on Porphyromonas gingivalis (Pg),and to explore an optimized protocol for a safe dose of photodynamic therapy (PDT) to eliminate periodontal pathogens as well as the impact on the implant surfaces,so as to provide theoretical and experimental basis for PDT in periimplantitis therapy.Methods Artificial in vitro models were formatted by culturing Pg standard strain and ITI (International Team for Implantology) implants together in CDC broth.Then artificial in vitro models were treated by different doses of hematoporphyrin monomethyl ether (HMME) and different energy density of laser (EDL) for 60 s.The cultures were counted by colony form unit (CFU),and SPSS 17.0 statistical software was used for data statistical analysis to select the best EDL and HMME dose.Finally,ITI implants were observed by scanning electron microscope (SEM) to evaluate the impact of HMME-PDT on Pg of implant surfaces.Results When EDL was 12 J/cm2 and mass concentration of HMME was 25 μg/ml,SEM observations showed that PDT could effectively kill Pg ((13.00±5.00) CFU)without damaging the implant surfaces.Conclusions PDT therapy combining 630 nm diode laser with photosensitizer HMME have good bactericidal effect on Pg,and the EDL and HMME dose is as small as the clinical applicable safe dose.

Objective To elucidate the effect of human leukocyte antigen(HLA)cross-reactive groups(CREGs)matching on the patient/graft survival rate of renal transplant recipients positive for penal-reactive antibody(PRA).Methods The PRA level and the HLA antibody specificity of renal transplant candidates were assayed using the LAT1240,LM720R,and SSP2LB kits.The appropriate donors were selected according to the CREGs matching standard.Results 112 recipients included 43 positive cases of HLA classⅠantibody,39 positive cases of HLA classⅡantibody,and 30 positive cases of bothⅠandⅡ.The HLA mismatching cases of 0,1,2,3,4 and 5 allele(s)were 6,39,38, 21,7 and 1,respectively.Hyper-acute rejection(2 cases),acute rejection(18 cases),chronic rejec- tion(5 cases),delayed graft function(4 cases),graft excision(one case)due to rejection and deaths (13 cases,5 with a functioning graft)occurred after transplant.Ninety-nine recipients and 96 grafts survived.The 1-,3-,and 5-year graft survival rate was 91.96%,86.96%,and 86.21%,respec- tively.Conclusion The HLA matching rate of patient/graft was elevated significantly and the effect of high PRA level was decreased according to the principle of CREGs,which increased the patient/graft survival rate remarkably in sensitized recipients.

Purpose To describe the clinical and pathological features of atypical vascular lesions (AVLs) after conservative surgery and radiation of the breast cancer,and to discuss the association with post-radiation angiosarcoma.Methods The clinical and pathological features in one case of AVLs was evaluated.The literatures were reviewed.Results The patient is a 57-yeAR~-old female who underwent a conservative surgery of the right breast because of a carcinoma.She received standard dose of radiation as adjuvant therapy.Three years later, multiple erythematous plaques developed around the former scar, which radiated to the nipple.Clinically,the plaques were considered as relapses of the carcinoma.However, fine needle aspiration gave negative results.Biopsy of one large plague revealed a circumscribed vascular lesion confined to the superficial dermis.It was composed of thin-walled anastomosing lymphatic vessels lined by attenuated endothelial cells.In focal areas, the vessels extended to the mid-dermis.Immunohistochemically, the endothelial cells were positive for CD31, CD34 and D2-40,with absent of α-SMA positive pericytes.Review of the breast tumor sections showed an invasive micropapillary carcinoma.Conclusions AVLs is a rare vascular lesion related with conservative surgery and post-radiation therapy of the breast.AVLs may represent as a precursor of breast angiosarcoma.Being familiar with the clinicopathologic characteristics of AVLs is important not only for the pathologists but also for the clinicians.
