Objective To avoid complicated wiring, a ward calling system based on wireless protocol is studied. Methods The system adopted ZigBee protocol, composed of calling console as network coordinator, bed-extensions as terminals and network routers in each ward. Results After initial configuration, the system could ring an alarm and gave the patient's bed number and ward number when patients called. Also it provided the automated network faults detection system. Conclusion The system is characterized with convenient installation, high intelligence and easy expansibility, and accords with the trend of technology.

Advanced gastric cancer has a low survival rate while traditional Chinese medicine (TCM) therapy has effects in inhibiting tumor growth, lengthening survival time and improving the quality of life.

砄bjective: To observe NO level in gingival tissue of elderly patients with periodontitis. Methods: 4 mm 3 gingival tissue was obtained during tooth extraction and NO in the tissue of 14 patients aged 65～81 years with periodontitis was measured with nitrate reductase assay. The NO level was compared with that of 9 adult patients (40～58 years old), 6 juveniles patients (25～30 years old) with periodontitis and 9 health elders(65～77 years old).Results:NO(?mol/L)in gingival tissue of elderly patients,health elders,adult patients and juvenile patients were 33.07?12.02,63.53?18.23,55.99?22.40 and 82.15?30.35 respectively.( P

Since the hospital metrology station is the principal part of military metrology system,its handwrought operation greatly affects the working efficiency and implementation effects.In order to enhance working automatization,some metrology software was developed,but they only focused on the metrology management.This software achieves more functions such as auto-hint,auto-count of the inspection parameters,auto-output of the certification and so on.

A century ago the Flexner Report facilitated the process of modern medical education reform.Half a century ago,Problem-based learning initiated the student-centered medical education model.At present training medical students' competency will usher in the third reform in medical education.Over 100 years' development and in the global context of current medical education reform,China's medical education has become an important part of the world medical education.Harbin Medical University conducted an all-around reform through international cooperation and received the accreditation referenced according to global standards in medical education,which is an epitome of the medical education reform in China.

Objective To investigate the expression of serum sHLA-G in systemic lupus erythematosus (SLE) patients and the association with the disease activity.Methods The serum concentration of sHLA-G in SLE patients and healthy controls was measured with enzyme-linked immunosorbent assay.Results Significant higher sHLA-G levels were detected in patients of SLE than control group (P＜0.01),The serum concentrations of sHLA-G in active SLE patients were markedly higher than stable SLE patients (P＜0.01).The expression level of sHLA-G showed positive correlations with SLE activity index (SLEDAI)(r=0.30,P=0.01).There was no correlation between sHLA-G levels and serum concentration of Anti-dsDNA,C3,C4 and Anti-ANA in SLE patients (P＞0.05).Conclusion The level of serum sHLA-G is significantly increased in SLE patients.Positive correlations are observed between sHLA-G levels and SLEDAI.These data indicated that sHLA-G may play certain roles in the pathogenesis and progress in SLE.

OBJECTIVETo explore treatment effect of the locking plate percutaneous external fixation to tibial fractures.

METHODSFrom July 2010 to February 2013, 8 cases with pediatric tibial fractures were treated by using unilateral locking plate percutaneous external fixation,including 6 males and 2 females with an average age of 7 years old ranging from 4 to 10. Among them, 5 cases were open fractures involving 1 case of Gustilo-Anderson type II, 3 cases of type III A, 1 case of type III B; and the other 3 cases were closed fractures involving 2 cases of AO type A3, 1 cases of type B2. The postoperative bone healing and gait impact were observed and the function was evaluated by Johner-Wruhs scores.

RESULTSAll fractures healed successfully without infection. The fracture healing time was from 3 to 6 months with an average of 3.9 months. The locking plate removal time was from 4 to 7 months with an average of 4.3 months. Among them, 7 cases were visually normal after walking with stand, 1 case of anterior tibial tendon defect affected gait. The results of Johner-Wruhs assessment were excellent in 7 cases, good in 1 case. No rub contralateral medial calf skin wounds occurenced.

CONCLUSIONThe method is simple, stable and reliable. The fixation strength is suitable for children using locking plate percutaneous external fixation. The postoperative functional recovery was excellent and the walking gait was less affected. But the point of LCP pedicle screw should be carefully selected before installation with good skin coverage.

Objective To explore the effect of pre-hospital nursing intervention in the new regional cooperative rescue model on treatment delay and the therapeutic effect in patients with myocardial infarction.Methods From January 2012 to May 2014,158 patients with acute myocardial infraction (AMI) were selected.Patients were divided into two groups,intervention group and control group,The first medical contact to balloon(FMC-to-B) time,referral time,cardiac function were analysed.Results Mean FMC-to-B time [(94±21)min vs.(102±23) min],referral time in nursing intervention [(5±3) min vs.(9±4) min)] were significantly shorter than those in control group (t=2.14,6.67,P＜0.05).After a month compared with control group,LVEF was increased [(54.8±6.9)％ vs.(48.8±6.9)％],and LVED was deceased [(50.1±8.2) mm vs.(50.5±5.6)mm] in intervention group.Conclusions Pre-hospital nursing intervention can decrease the FMC-to-B time,which could improve the cardiac function.

The weakness of the boiler high pressure steam sterilizer is put forward.The development process and actual application value of the hot steam electrical generator is mainly introduced.

Objective To analyze the clinical features of 35 patients with Silver-Russell syndrome (SRS) in Beijing Children's Hospital in recent 6 years,and to recognize the clinical manifestations and improve the diagnosis of the disease.Methods The diagnostic criteria of SRS were studied retrospectively,the differences among 3 different diagnostic criteria were compared.Results Thirty-five SRS patients were diagnosed by means of 3 criteria,over a period from 2006 to 2012.There were 23 males and 12 females,with age range 0.08 ～ 12.15 yr.77 ％ of cases met the three criteria,97％ met two of the three criteria.There were dwarfism in 33 cases (94.2％),genital abnormalities in 1 case (2.9％),and asymmetry of limbs in 1 case (2.9％).The clinical characteristics with the frequencies accounting for over 80％ included short stature (average height-3.61 SDS),leanness (body mass index ＜-2.11SDS),bone dysmorphism including triangular face,irregular teeth,asymmetry of limbs,clinodactyly of fifth finger,and bone age obviously lagged behind.60％ of the cases showed bone age lagging behind more than 1 year.Height lagging behind was more obviously then bone age.Conclusions The diagnosis of SRS is mainly based on Clinical manifestation,laboratory and biochemical examinations are of no avail.There is a high coincidence with the 3 different diagnostic criteria.Clinical features in more than 80％ patients with SRS are short stature,craniofacial triangular dysmorphism,irregular teeth,limbs asymmetry and fifth finger clinodactyly,and mild lagging behind of bone age.
