The main functions of modern Clinical Engineer(CE) is discussed. By combining experience of clinical engineering in developed country with clinical practice in our country, the work character problem of clinical engineering was proposed. According to the reality of equipment management and operation, the function of CE is not only to ensure medical equipment to run normally but also estimate the value of equipment in before buying or abandoning, PSS and technology study. Through the efforts of CE, the main functions of equipment can be made the best, medical therapy and new method research is more efficient.

Diffuse large B-cell lymphoma (DLBCL) represents the most common type of malignant lymphoma. DLBCL is heterogeneous with respect to morphology, immunophenotype, biology, clinical presentation and outcome. Constitutive activity of the NF-κB pathway may contribute to the poor prognosis of patients with activated B cell-like (ABC) subgroup of DLBCL, caspase recruitment domain 11 (CARD11) is the important signal protein in the signaling pathway of NF-κB. Furthermore, various pre-clinical data have proved the importance of CARD11 in DLBCL. This review summarizes the biological characteristics of CARD11, and its relationship with NF-κB signaling transduction pathway and the outcome of DLBCL, so that we can better understanding the pathogenesis and new therapeutic target of DLBCL.

With rapid advancements in internal fixation and new surgical instruments, surgical treatment has gradually emerged as the first treatment choice for mandibular condylar fractures. An appropriate surgical incision is the first and determinant step during surgery to avoid postoperative complications. Hence, surgical approaches in relation to oral and maxillofacial trauma surgery for the treatment of mandibular condylar fractures have been extensively investigated. This review summarizes the research progress on surgical approaches in the management of mandibular condylar fractures.

OBJECTIVE:To provide reference for standardized dispensation of chemotherapy drugs in PIVAS.METHODS:Cautions for the dispensation of chemotherapy drugs and process steps of emergency were introduced as well as the disposal of waste and liquid after dispensing.RESULTS & CONCLUSIONS:Centralized and standardized dispensation of chemotherapy drugs in PIVAS improves the quality of the dispensation of chemotherapy drugs.And it ensures the safety of drug use and strengthens the occupational protection of staff.

Objective To study and evaluate the inhibitory role of ?-carboxyglutamic acid(Gla)in the Gla domain of prothrombin in the formation of calcium oxalate crystals. Methods The addition of morpholine and formaldehyde to the solution of prothrombin caused the conversion of 8 Gla to ?-methyleneglutamic acid (8?-MGlu)or 2 Gla to ?-methyleneglutamic acid(2?-MGlu) ,the inhibitory activity of which to calcium oxalate crystallization was detected with seeded crystallization technique. Results The conversion of Gla to ?-MGlu leads to the decreased inhibitory activity of prothrombin to calcium oxalate crystallization,the inhibitory index being decreased from normal 14.2 to 12.8 of 2?-MGlu or 5.0 of 8 ?-MGlu prothrombin respectively. Conclusions Gla in prothrombin may play an important role to inhibit the formation of calcium oxalate calculi.

Objective To explore the diagnostic value of cerebrospinal fluid(CSF) biochemical indexes in central nervous system (CNS) infection .Methods The results of CSF culturing and detection of biochemical indexes including glucose(Glu) ,lactate dehy‐drogenase(LDH) ,chloride ion(Cl) and protein(PRO) were collected from the First Affiliated Hospital of Xi′an Jiaotong University from September to December 2013 .Taking the results of CSF culturing as golden standard ,the biochemical indexes were analyzed by using receiver‐operating characteristic(ROC) curve for single index and combined indexes .Results A total of 157 CSF speci‐mens were collected ,including 39 culture‐positive specimens and 118 culture‐negative specimens .Areas under ROC curve(AUC) of Glu ,LDH ,Cl and PRO were 0 .653 ,0 .633 ,0 .626 ,0 .671 ,respectively .The AUCs of combined detection of these biochemical inde‐xes were higher than those of single index ,and the AUC of combined detection of these four indexes was the largest ,up to 0 .694 , but all were less than 0 .7 .Conclusion Glu ,LDH ,Cl and PRO all could be independent biochemical indexes for diagnosing CNS in‐fection ,among which PRO has the highest diagnostic value .And combined detections of these indexes are better than single detec‐tions ,especially combination of four indexes ,which is the strongest indicator ,but accuracy is low whether single or combined detec‐tion .More sensitive and specific biomarkers of CSF should be explored for rapid diagnosis of CNS infection .

Objective To investigate the efficacy of wrist three-needle acupuncture in treating pre-adhesive stage scapulohumeral periarthritis. Method Seventy-eight patients with pre-adhesive stage scapulohumeral periarthritis were randomly allocated to two groups. The treatment group of 39 patients received wrist three-needle acupuncture and the control group of 39 patients, conventional acupuncture. Result After one course of treatment, the cure rate and the total efficacy rate were significantly higher in the treatment group than in the control group and there was a statistically significant difference (P<0.05). There was a statistically significant pre-/post-treatment difference in the VAS score in the treatment group (P<0.05). There was a statistically significant difference in the pre-/post-treatment difference value between the treatment and control groups (P<0.05). Post-treatment pain relief rate was significantly higher in the treatment group than in the control group (P<0.05). Conclusion Wrist three-needle acupuncture is even more effective than conventional acupuncture in treating pre-adhesive stage scapulohumeral periarthritis.

ObjectiveTo investigate the clinical efficacy of electrothermic acupuncture in treating knee osteoarthritis.Method One hundred and twenty patients were randomly allocated to treatment and control groups, 60 cases each. The treatment group received electrothermic acupuncture and the control group took Xianlinggubao capsules orally. The clinical therapeutic effects and changes in the WOMAC score were observed in the two groups after four weeks of treatment.ResultThe total efficacy rate was 95% in the treatment group and 85% in the control group. There was a statistically significant difference in clinical therapeutic effect between the two groups (P<0.05). There was a statistically significant difference in pre-/post-treatment WOMAC score difference value between the two groups (P<0.05).ConclusionThe clinical efficacy of electrothermic acupuncture is better than that of Xianlinggubao capsules in treating knee osteoarthritis with yang deficiency and cold congealment.

Objective To explore the diagnostic value of SPECT/CT on fracture healing.Methods A total of 28 patients (13 males,15 females; average age 45.3 years) with fracture were enrolled.All underwent metal fixation.SPECT/CT scans were performed at least 6 months after the metal fixation.X-ray examination before SPECT/CT showed equivocal fracture healing.The fracture delayed union or nonunion were judged by degree of uptake as well as uptake pattern around fracture site.Final diagnosis was confirmed by surgery or follow-up X-ray film.Results Among 28 patients,15 showed delayed union (confirmed by follow-up),and 13 showed nonunion (confirmed by surgery).There were 13 screws in 6 patients showed abnormal uptake,suggesting screw loose (confirmed by surgery).Conclusions SPECT/CT imaging could be of clinical significance in assessing fracture healing.

Objective To investigate the effect of rosiglitazone on the expr es sion of PPAR?,TGF-a1 and PCNA and its mechanism on renal interstitial fibrosi s following unilateral ureteral obstruction(UUO) in rat kidney. Methods Thirty r ats were randomly assigned to shame operation group(sham group),UUO group, rosig litazone(5 mg穔g-1?d-1) treatment group after UUO. Immunohistochemistry,RT-PCR,Western blotting were performed to investigate renal pathological changes an d examine the expression of PPAR?,TGF-a1,PCNA on the 7th and 14th day in the kidney. Results In comparison with the shame group,the expression of PPAR?,TGF-a1,PCNA of UUO and treatment groups increased significantly(P
