Objective:Toclone the OPGgene ofhuman beingand construct its recombinant adenovirus and then observe its effects on the differentiation of bone marrow stem cells(BMSCs).Methods:The cDNAs of human OPG in hepatic tissue were obtained by using RT-PCR method.The cDNAs then were recombined with competent homologous cells to form the AdOPG and the shuttle vector was used during this stage.The rabbit BMSCs were isolated and cultured in vitro,and were infected with AdOPG.The OPG expression of BMSCs was identified by RT-PCR and Western blot.The expression of ALP was detected by chromatometry and ALP dyeing five days after the infection.Results:The OPG gene of human being was successfully cloned and its sequence consistent with the Gene bank.The titre of constructed AdOPG can reach 109 efu/ml.The ALP activity of BMSCs was(21 024?507)IU five days after the infection of AdOPG,whereas the value was(3 079?89)IU in the control group and(2 156?78)IU in the blank control group.Conclusion:The OPG can induce the osetogeinc differentiation of BMSCs.

The article teased the concept of medical futility and analyzed the issues when implement the medical futility policy.It introduced the medical futility policy by the examples of New York Public Health Code Article 29-B:Orders Not to Resuscitate and relevant regulations in Taiwan and presented some reflections on medical futility.The authors suggested that it should cope with the common and troubled cases of medical futility,establish ethics committee,and make the medical futility policy at the stage of tense doctor-patient communication.

OBJECTIVE:To observe the clinical effect of tiotropium bromide combined with salmeterol xinafoate and fluticasone propionate in the treatment of medium and severe COPD. METHODS:119 patients with medium and severe COPD were divided into control group(54 cases)and observation group(65 cases)according to admission order. Control group was treated with Salmeterol xi-nafoate and fluticasone propionate powder for inhalation 50 μg,bid;observation group was additionally given Tiotropium bromide powder for inhalation 18μg,qn. Both groups received 1 month of treatment. Lung function indexes as FEV1,FVC and IC,blood gas indexes as SaO2,PaCO2 and PaO2 and inflammatory factors as IL-8 and TNF-α,COPD assessment test(CAT)score were observed in 2 groups,and the occurrence of ADR was also observed. RESULTS:Before treatment,there was no statistical significance in above indexes between 2 groups(P>0.05). After treatment,FEV1,EVC,IC of observation group were increased significantly,SaO2 and PaO2 of observation group were increased significantly,while PaCO2,IL-8 and TNF-αlevels was decreased significantly;those index-es of observation group were significantly better than those of control group,with statistical significance(P<0.05). CAT score of 2 groups were decreased significantly compared to before treatment,and the observation group was significantly lower than control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Tiotropium bromide com-bined with salmeterol xinafoate and fluticasone propionate shows good clinical efficacy and safety in the treatment of medium and se-vere COPD.

Objective To observe the therapeutic efficacy of centro-square needling plus stuck needling with lifting-thrusting manipulations in treating the injury of medial collateral ligament (IMCL) of knee joint. Methods Seventy-eight patients with IMCL of knee joint were randomized into a treatment group of 40 cases and a control group of 38 cases. The treatment group was intervened by centro-square needling plus stuck needling with lifting-thrusting manipulations, while the control group was by local anesthesia treatment. The therapeutic efficacies were compared between the two groups. Results The total effective rate was 97.5% in the treatment group versus 81.6% in the control group, and the difference was statistically significant (P＜0.05). Conclusion Centro-square needling plus stuck needling with lifting-thrusting manipulations is an effective way in treating IMCL of knee joint.

Objective To develop an informatized continuous education system for theater nurse based on PDCA theory.Methods The system was gifted with the functions of learning planning, learning execution, learning checking, data management and system management based on PDCA theory, informatized technology and other learning systems.Results The system behaved well in overall flow and configuration, man-machine interaction and application, which facilitated the nurses to learn with fragmented time.Conclusion The nursing continuous education is enhanced greatly with the system.

Objective To explore the application of cognitive intervention and drug intervention in patients with chronic obstructive pulmonary disease(COPD).Methods A total of 86 patients with chronic obstructive pulmonary disease(COPD)admitted from February 2016 to July 2016 were included in this study.The patients were divided into experimental group and control group according to the order of admission.43 patients in the control group received routine measures,In the experimental group,43 patients received cognitive intervention and drug intervention,compared the clinical treatment effect and treatment compliance of the two groups after intervention.Results The compliance rate of disease cognition,smoking,medication,pulmonary function,family oxygen therapy,respiration exercise,rehabilitation therapy,nutritional support and influenza vaccination were significantly better in the experimental group than in the control group(P<0.05)(1.2±0.7)times,the number of acute attack was(2.0±0.8)times and the quality of life was(4.4±0.9)points,which was significantly better than that of the control group(P<0.05).Conclusion Cognitive intervention and drug intervention have a positive effect on the treatment compliance of patients with chronic obstructive pulmonary disease,improve the quality of life of patients,and have significant clinical application value.

OBJECTIVE:To evaluate the utilization of blood lipid-lowering drugs in Haikou area.METHODS:The consumption sum,DDDs and DDC of blood lipid-lowering drugs in 2 hospitals of Haikou area from 2007 to 2009 were analyzed retrospectively.RESULTS:The consumption sum of blood lipid-lowering drugs in Haikou area increased year by year,up by 41.25% in 2008 than in 2007 and 28.96% in 2009 than in 2008.Blood lipid-lowering drugs were mainly atorvastatin,pravastatin,fluvastatin,simvastatin,bezafibrate.Atorvastatin took up the first place of the list of consumption sum and DDDs in past 3 years.CONCLUSION:Statins occupy the predominate place among blood lipid-lowering drugs and show potential in the market.

BACKGROUND:Anterior cruciate ligament (ACL) reconstruction is the primary treatment method for ACL rupture. Currently, studies on ACL reconstruction involve histology and embryology, anatomical structure, biomechanics, reconstruction materials, operating technology, and rehabilitation after reconstruction. However, clinical epidemiological studies describing ACL rupture and reconstruction remain scarce. OBJECTIVE:To analyze the clinical epidemiological characteristics of ACL rupture and reconstruction to provide guidance for prevention and treatment of ACL rupture. METHODS:Data of 352 patients forage, gender, cause and mechanism of injury,treatment time, and the impact of ACL rupture on menisci and articular cartilage were gathered. Meanwhile, the events during surgery, operation methods and reconstruction materials were analyzed. RESULTS AND CONCLUSION:ACL rupture mostly occurred in young men,andhappened more often to theleft knee; male patients got hurt in basketbal, footbal and accidental injuries,whilefemale patients got hurt in the accidental injuries, badminton and sking injuries, internal rotation with valgus stress accounted for the predominant injury mechanism. The ACL reconstruction wasmostlyperformedwithin1-3 months after ACL rupture, often accompanied by meniscal and articular cartilage damage. Lateral meniscus injury incidence was relatively stable, medial meniscusinjury incidence increased significantly over the half year after ACL rupture. Most articular cartilage injury occurred to patelar cartilage.Asignificant increase in medial condylar cartilage damage over 1 year after ACL rupturewas often observed. Anatomic single-bundle ACL reconstruction was the primary surgical approach, the resident ridge and the lateral bifurcate ridge could be used to position bone tunnel and autogenous semitendinosus and gracilis tendon were the most commonly used reconstructionmaterials. Our results indicate that anatomic ACL reconstruction should be performed as early as possibleinrestore knee joint stability and prevent secondary injury of the medial meniscus and cartilage of medial femoral condyle.
