Purpose:To observe the effective of gemcitabine in elderly patients(pts) with advanced non-small-cell lung cancer(NSCLC), compared to supportive care alone. Methods:Gemcitabine group (n=21), received gecitabine (1 250) mg/m~(2), on days 1 and 8,using 21-day schedule, total 4 cycles. Control group (n=23) , using supportive care alone. Results:The overall response rate of gemcitabine group was 28.6%, 6 had partial response(PR), 12 had stable disease(SD),3 had progression disease(PD).No patient had complete responses (CR) and PR in control group. The median duration of response was 6.3 months in gemcitabine group, the median survival was 12.8 and 4.6 months respectively (P

Medical equipments are essential supplies to carry out medical work. How to ensure the safety and reliability of the medical equipments in diagnosis, and reduce procurement and maintenance costs is a topic of concern to everyone. In this paper, product lifecycle management (PLM) and enterprise resource planning (ERP) are cited to establish a lifecycle management information system. Through integrative and analysis of the various stages of the relevant data in life-cycle, it can ensure safety and reliability of medical equipments in the operation and provide the convincing data for meticulous management.

Medical consumables material is essential supplies to carry out medical work, which has a wide range of varieties and a large amount of usage. How to manage it feasibly and efficiently that has been a topic of concern to everyone. This article discussed about how to design a medical consumable material management information system that has a set of standardized processes, bring together medical supplies administrator, suppliers and clinical departments. Advanced management mode, enterprise resource planning (ERP) applied to the whole system design process.

There exists the contradiction between medical value and social ethics on human-body experiments,so the ethics requires that we should set a comprehesive appraise and choose the corresponding ethical principle to standardize the behavior of human-body experiments.

Through introducing the current situation of systemic pediatric emergency protocol,including five-level triage system,pediatric critical rescue protocol,pediatric trauma life support,emergency observation and guidelines for the pediatric intrahospital transport,we reviewed the issues of pediatric emergency to put forward recommendations.

Objective To evaluate the effect of multiple adhesion molecules ICAM-1、CD_ 44 V6、CD_ 28 、E-cad and CEA in organic selection of gastric carcinomatous metastasis.Methods Eighty-four gastric carcinoma cases(32 cases without metastases,52 cases with transfer to liver、marrow、lymphonode、lung、kidney or belly cavity),were take operation sample or tissue under gastroscopy,being made cells single by primary culture,then were detected the expression of 5 kinds of adhesion molecules by ABC immunohistochemistry,positive rate was recorded.Results ICAM-1 had high expression in cases with marrow or lung metastasis,while low expression in cases with lymphonode metastasis.CD_ 44 v6 had high expression in cases with lymphnode or liver metastasis.CD_ 28 had high expression in cases with liver、lung or kidney metastasis.E-cad had high expression in cases with marrow metastasis,while low expression in cases with other metastasis.CEA had especially high expression in cases with liver、belly cavity or lymphnode metastasis.Conclusion High or low expression of adhesion molecules ICAM-1、CD_ 44 V6、CD_ 28 、E-cad and CEA plays a certain role in organic selection of gastric carcinomatous metastasis.

[Objective] To study the inhibitory effect of bcl-2 antisense oligonucleotide(ASODN)combined with radiation on lung carcinoma cells NCI-H446.[Method]The cultured NCI-H446 lung carcinoma cells were divided into 5 groups:control,pure radiation,nonsense+radiation,lipofectin+radiation,ASODN+radiation.Every group except for control were assayed by MTT on the inhibition rates,24h,48h,72h after 10Gy irradiation respectively.[Results]The inhibitions of lung carcinoma cells NCI-H446 were observed in ASODN+radiation,lipofectin+radiation,nonsense+radiation and pure radiation groups.The differences between the ASODN+radiation group and the other three groups were significant(P

Objective To observe the effect of hyperbaric oxygen therapy (HBOT) on mineral density and biomechanics of new-formed bone in distraction gap.Methods The mandibles were subjected to osteotomy and distractors were placed bilaterly in 30 rabbits,which were divided randomly into 2 groups.After 5 days for latency,the mandibles were distracted at a rate of 0.8 mm/day for 10 days,and then for consolidation.After surgery,group A received HBOT with daily distraction,whereas group B only distracted without HBOT served as control group.The animals in groups A and B were sacrificed 1 wk,2 wk,4 wk of consolidation,respectively.The mandibles were harvested and subjected to examination for new bone formation,and bone mineral density (BMD) and biomechanics of newly formed bone in the distraction gap.Results At one week of consolidation,no significant differences were observed between the BMD of newly formed bone in the two groups (P＞0.05);however,at the other time points,BMD of newly formed bone in group A was significantly higher than that in group B (P＜0.05).Moreover,at 4 weeks of consolidation,the strength,maximum fragile energy and modulus of elasticity of newly formed bone in group A were significantly higher than those in group B (P＜0.05).Conclusions The results suggest that HBOT improves mineral density and strength of new formed bone in distraction gap.

The management for qualification documents of medical instruments is very important work to management department of medical instruments. Because the number of qualification documents of medical instruments is very large and they have an expiry date, it is difficult to manage them. This article discussed how to manage qualification documents of medical instruments, and an information management system that has a function of traceability management has been developed. This information management system standardizes management for qualification documents of medical instruments, and ensures that qualification documents of medical instruments are available and can be traced. Besides, it can reduce the amount of work for medical instruments management.
