OBJECTIVETo develop and evaluate the short version of patient reported outcomes (PROs) questionnaire for gastric stuffiness (Wei Pi) patients with modern test theory and technologies, hoping to provide testing tools for related clinical practice and scientific researches with higher quality and less administrative and response burdens.

METHODSUsing descriptive study design, clinical data were collected with sociological questionnaire and previous developed full items version of PROs instrument for gastric stuffiness (Wei Pi) patients via field and online surveys between Sep 2011 and Mar 2012. The statistical analysis group identified the termination parameters firstly, and then selected items with discrimination, fitting residual, item information curve (IIC) , item characteristic curve (ICC), and the rank of computerized adaptive testing (CAT) select proportion, etc. After assumption evaluation of item response theory (IRT), IIC, ICC, difficulty coefficient distribution, items-response relation and thresholds, etc. were used for psychometric evaluation of instrument.

RESULTSA total of 331 patients [Ages: 31.99 +/- 10.29 yrs; Male: 186 (56.3%)] were enrolled in statistical analysis. The test termination criterion was Max SE = 0.2 or Max items number =16. After items selection, a 15-item short version of instrument, which contains symptoms facet (8 items) and impact facet (7 items) was generated. With good unidimensionality, local independence, and monotonicity, the IC and ICC in IRT analysis showed good working capability of the questionnaire. The difficulty coefficient distribution and items-response relation were also rational, as well as response thresholds.

CONCLUSIONSThe short version of PROs instrument for adult gastric stuffiness (Wei Pi) patients was successfully developed and assessed. The instrument with good methodological and reporting quality could be used in clinical and scientific evaluating their symptoms and impact.

OBJECTIVE: To investigate the influence of demographic and clinical characteristics, stress, and coping style on disease self-management in children and adolescents with type 1 diabetes. METHODS: A cross-sectional survey was performed to select 149 children and adolescents with type 1 diabetes (aged 8-20 years). Related data were collected using the questionnaires and scales on general information, diabetes self-management, perceived stress, and coping style. RESULTS: Of the 149 children and adolescents, 37(24.8%) had high stress. Compared with the school-aged children, the adolescents had higher stress level and were more likely to present with negative coping style (P<0.05). The multiple linear regression analysis showed that the children whose mothers had an educational level at or above senior high school, who had a low stress level, and who adopted positive coping measures had a higher level of diabetes self-management (P<0.05). CONCLUSIONS Nearly a quarter of the children and adolescents with type 1 diabetes have a high stress level. When delivering the education on diabetes self-management to children and adolescents, healthcare workers should focus on the families whose mothers have an educational level at or below junior high school. Strategies should aim at reducing stress by encouraging positive coping styles.

ABSTRACT:OBJECTIVE To explore the mechanism of treating Alzheimer's disease model rats by electro-acupuncture through detecting the phosphorylation of p38MAPK and tau protein in hippocampus.METHODS SD rats were randomly di-vided into control group,sham-operated group,model group and electric-acupuncture group.The model group and electric-ac-upuncture group were injected with Aβ1-40 into hippocampus.20 d later,the electric-acupuncture group had electric-acupuncture at Baihui(GV20) and Shenshu(BL23)appoints.Morris Water Maze was used to observe rates memory abilities,and western blot and immunohistochemistry were used to determine the expression of p-p38MAPK and p-tau181.RESULTS The electric-acupuncture group significantly improved learning and memory abilities(P <0.05);expression of p-p38MAPK and p-tau181 in the model group was significantly higher than the others,while significantly reduced after electric-acupuncture treatment(P <0.05).CONCLUSION Acupuncture can regulate expression of p-tau181 through p38MAPK signaling pathway and improve the learning and memory ability of AD rats.

Objective To evaluate the long-term results of short implants and assess its clinical importance. Methods A total of 77 short implants were consecutively placed in 43 patients from August 1998 to August 2004. The clinical data was reviewed and the crown-implant ratio (C/I) was measured.Twenty-nine short implants in 15 patients were loaded for more than 5 years and the marginal bone height around implant measured. The implant success and survival ratio were evaluzted according to Zarb's successful criteria and Wheeler's survival criteria. Results The mean follow-up time was 5.4 years (36 ～99 months). Among these 77 short implants, 74 implants were fixed restoration, which mean C/I was ( 1.08 ±0. 21 ), 3 implants were removable restoration. Of 29 short implants which were loaded for more than 5 years, the mesial bone height at the times immediately after inserting implant, before second stage surgery, loading for less than 3 years and loading for more than 5 years was (0.59 ±0.66), (0.64 ±0. 59 ), ( - 0. 05 ± 1.11 ), ( - 0. 37 ± 1.29 ) mm; and the distal bone height was ( 0. 62 ± 0. 77 ), (0. 60 ±0. 86), ( -0. 26 ± 1. 12), ( -0. 23 ± 1. 59) mm. The 5 year's survival rate and success rate were 97% and 93% respectively. Conclusions The success and survival rate of short dental implant under function were comparable to those reported for normal implants. By using the short implant, the patients can avoid the graft operation, alleviate sufferings, shorten the treatment period and reduce the cost. Therefore, it has a high value in clinical application.

Objective to explore the effect of catheter based renal symthetic denervation on reninangiotensin-aldosterone system(RAAS)and blood pressure reduction in patients with resistant hypertension.and assess the validity and security of the treatment.Methods Ten patients with resistant hypertension from June 2011 to December 2011 were retrospectively reviewed,and then all of 10 patients screened for eligibility were allocated to renal denervation.Primary endpoints were changes of office blood pressure at 1week,1,3 and 6 months after procedure.We assessed the effectiveness of renal sympathetic denervation with heart rate (HR),renin activity (PRA),angiotensin Ⅱ (Ang Ⅱ),aldosterone(Ald),and creatinine(Cr)before and 2 weeks after procedure.Results Office blood pressure after catheter-based renal denervation decreased by 22.8/9.1 mm Hg(1 mm Hg =0.133 kPa),34.8/14.7 mm Hg,42.6/20.7 mm Hg,43.2/21.6 mm Hg,at 1 week,1,3 and 6 months,respectively(P ＜ 0.001).Meanwhile,the level of PRA,Ang Ⅱ,Alddecreased by (1.11±0.89)ng· ml-1 · h-1(P=0.003),(17.06±13.82) ng/L (P=0.004),(404.5 ±285.8) ng/L (P =0.002),respectively； and heart rate decreased by 5.1 bpm (P =0.002).However,the Cr level and eGFR did not change significantly (P ＞ 0.05).Conclusion Catheter-based renal sympathetic denervation can reduce the level of renin activity,angiotensin Ⅱ and aldosterone,and causes substantial and sustained blood-pressure reduction.

OBJECTIVETo study the potentiality of osteanagenesis of the hematomas formed around the fractures and that of the marrow stroma cells, evaluate the effect of the combined trans-plantation of the hematoma and the marrow stroma cells, to explore a new method to accelerate the union of fracture.

METHODSThe bone defect models were made on the tibias of the New-Zealand's rabbits. The hematomas formed around the fracture were taken out 3 days latter after the operation, the marrow stroma cells were abstracted from the femoral marrow simultaneously. And then the mixture of the hematoma and the marrow stroma cells were transplanted to the defects of the tibias in the experiment group, and the hematoma transplanted simply to the same place in the control group. The radio-graph and the histological observation of the osteotylus were carried out regularly post-operation.

RESULTS1) There was a significant difference in osteotylus quantity between the two groups: more osteotylus and obvious periosteal proliferation were found in the experiment group than that in the control group which accepted the transplantation of the hematomas alone. 2) There was a significant difference in osteoblast number between the two groups: more sclerotomal-like cells were observed under the microscope in the experiment group than that in the control group.

CONCLUSIONMarrow stroma cells have great potentiality of osteoanagenesis. The result of combined transplantation of the marrow stroma cells and the hematomas is more effective than that of simple transplantation of the bone hematoma.

Objective To improve vibration resistance of conventional blood transportation kits and mitigate hemolysis during transportation.Methods The structure of a blood transportation kit was modified.We installed a suspension brac-kets within the kit,added buffer material between the brackets,and tested the vibration-suppressing effect compared with the conventional blood transportation kit.Results Rubber and plastic materials between brackets were added,and double membrane suspension brackets were installed.After 4 and 6 min of vibration,free hemoglobin(FHb)[(1559.7 ±1038.5) and(1886.2 ±1023.8)mg/L],lactic dehydrogenase levels[(135.3 ±67.7)and(195.7 ±123.6)U/L]and hemolysis rate[(0.35 ±0.34)%and(0.42 ±0.38)%]in the conventional transportation kit were significantly higher than in the vibration-suppressing kit.K+did not change significantly,and was comparable in both groups at each time point.After 4 and 6 min of vibration, FHb in the conventional transportation kit exceeded the standard.However, after 12 min of vibration,FHb[(560.1 ±342.3)mg/L]in the vibration-suppressing kit were within the standard range.No bacterial growth was detected in either group.Conclusion The vibration-suppressing kit under research shows a better 1986vibration-suppressing effect,which could improve blood support capability in case of emergency.

OBJECTIVE: To observe the expression and distribution of vascular cell adhesion molecule-1 (VCAM-1) and caspase-3 in myocardium of persons who died from viral myocarditis and to explore its pathogenesis and death mechanism. METHODS: Twenty cases died from viral myocarditis were selected as the experimental group. Ten cases died from traumatic shock and massive hemorrhage shock after traffic accidents were selected as the control group. The sections of myocardium were stained by immunohistochemistry for VCAM-1 and caspase-3, and observed under microscope. The positive expressions of VCAM-1 and caspase-3 of the two groups were compared with each other by image analysis and statistical analysis. RESULTS: (1) The vascular endothelial cells expressed VCAM-1 with dark-brown colors in the experimental group, and weak expression was observed in the control group. The average optical density in the experimental group was higher than that in the control group (P < 0.05). (2) The caspase-3 positive cells were mostly inflammatory cells around the myocardial vessels with brown-red granules in the experimental group. The positive cell number in the experimental group was higher than that in the control group (P < 0.05). CONCLUSION VCAM-1 may play an important role in the inflammatory cells exudation caused by viral myocarditis, and may provide the reference for diagnosis of viral myocarditis in forensic pathology. However, the myocardial apoptosis mediated by caspase-3 doesn't affect the lethal mechanism in the late stage of viral myocarditis.
