OBJECTIVE: The role of different local flaps in small external nasal skin defect reconstruction was discussed. METHOD: Forty-two cases of the small size nasal defects (diameter < 2 cm) were repaired with local external nose flap (includes the dorsal nasal flap, nasolabial flap and bilobed flap). The clinical and follow-up data were analyzed of patients with small external nasal skin defects, who accepted different local flaps reconstruction. Dorsal nasal flap, nasolabial flaps (includes island flap, slid flap and axial flap) and bilobed flap were tailored to reconstruct different external nasal defect. Twenty-seven patients were male and fifteen patients were female, the patients' age ranged from 28 to 74 years, the median age was 61 years. Thirty-eight cases resulted from resection of skin malignant tumor and four cases were benign lesions. The diameter of defects was 1-2 cm. The defects were reconstructed by single-stage dorsal nasal flap in 7 cases. There were 30 cases of caudolateral nasal defects were reconstructed by nasolabial flap, single-stage island nasolabial flap in 7 cases, axial flap in 18 cases and slid flap in 5 cases. Superior lateral defects were reconstructed by single-stage bilobed flap in 5 cases. RESULT: All defects were repaired successfully. All tissue flaps survived and had not necrosis. There was no tumor recurrence during 3 months to 2 years follow-up. CONCLUSION The dorsal nasal flap, nasolabial flap and bilobed flap can be used safely and effectively to repair the small external nasal defect and have satisfactory curative effect.

The ratio of plasma aldosterone concentration to plasma renin activity (ARR) is a practical parameter in screening for primary aldosteronism (PA).However,variations of the cutoff value of ARR in different studies have been reported due to plenty of influential factors that may affect the secretions of renin and aldosterone. Lack of standardization of assays for ARR also makes direct comparisons among different studies difficult.The associated influential factors on ARR were introduced in this review.

BACKGROUND:Bone nonunion is a common complication in the orthopedic treatment, and its morbidity reached 5%-10%, which results in the long-term functional disturbance of the limbs, and even disability. Autogenous iliac crest graft has been commonly used to treat bone nonunion, but some limitations stil exist.
OBJECTIVE:To investigate the treatment outcomes of autogenous iliac crest graft combined with autologous bone marrow stem cel transplantation for bone nonunion after fracture surgery.
METHODS:Clinical and fol ow-up data from 69 patients with bone nonunion were analyzed retrospectively. Al patients were al otted to combination (n=37) and iliac (n=32) groups, fol owed by treated with autologous iliac crest graft combined with autologous bone marrow stem cel transplantation or autologous crest graft, respectively. Afterwards, the hospitalization time, fracture healing time, bone mineral density and Fereadez-Esteve cal us scores were detected and compared between groups.
RESULTS AND CONCLUSION:The hospitalization time did not differ significantly between groups (P>0.05). The fracture healing time in the combination group was significantly shortened compared with the iliac group (P<0.05). The bone mineral density and Fereadez-Esteve callus scores in the combination group were significantly higher than those in the iliac group at 3 and 6 months after surgery (P<0.05). The excellent and good rate of the affected limb function in the combination group was significantly higher than that in the iliac group (P<0.05). These results suggest that autogenous iliac crest graft combined with autologous bone marrow stem cell transplantation for bone nonunion can accelerate fracture healing, promote porosis and improve the functional recovery of affected limbs.

Objective To establish a scientific and feasible evaluation index system of the quality of health education among the elderly in the community.Methods Based on the results of literature review,theory analysis,cross-sectional study and interviews,a draft evaluation index system was formulated.Then Delphi method was conducted on 28 specialists around the country,the weight of each index was determined by hierarchy analysis.Results After three rounds of Delphi procedure,the response rates of the three round consultation were all above 85％,and the authority coefficient and coordination coefficients was 0.858,0.210,respectively.An evaluation index system which covered three first-level items,7 second-level items and 35 third-level items was formulated.Conclusions Based on survey of the elderly and interviews of health education staffs in the community,and using the method of Delphi to collect experts' suggestion,a strong maneuverability and high reliability quality evaluation index system was formulated,which provided guidance for community health education of the elderly,and promoted its development towards scientization and standardization.

Objective The current study was designed to investigate the inhibitive effect of celastrol on the proliferation of acute myelogenous leukemia (AML) cells. Methods The effect of celastrol on AML cells in vitro was examined by MTT assay and flow cytometry (FCM). Results After the AML primary cells were treated with different concentrations of celastrol, the results were analyzed by MTT. The growth of the cells were significantly inhibited compared with the control group (P ＜0.01). The results detected by FCM showed that the apoptosis was seen after treated with celastrol with different concentration for different times.The apoptotic rates were significantly higher than that in the control group with statistical significance (P＜ 0.01).Conclusion Celastrol could inhibit the proliferation of AML cells in vitro, which may be associated with inducing cell apoptosis.

Objective To investigate regional ventricular long-axis velocity and adjacent intraventricular flow velocity using dual-pulse wave(PW) Doppler echocardiography synchronously,and to analyze the coupling relationship between regional ventricular long-axis strain and adjacent intraventricular pressure gradients in normal cases using dual-PW Doppler echocardiography.Methods Eighty-six normal subjects aged 19～66 years [mean age (37.49 ± 11.97)years] underwent routine echocardiography and dualPW Doppler echocardiographic exam.Total 18 segments were sampled using dual-PW Doppler (PW/TDI mode) images at basal,mid and apical levels on three standard apical views,and electrocardiogram was recorded simultaneously.Peak early diastolic velocity (emax),peak late diastolic velocity (amax),peak early mitral diastolic inflow velocity (Emax),regional peak early diastolic velocity (Em),regional peak late diastolic velocity (Am) and regional peak early diastolic inflow velocity (E) were measured simultaneously in the same one cardiac cycle.Myocardial variations of left ventricular segments were observed.Em,Am and E of different levels from different ventricular wall were analyzed.The co-relationship between regional ventricular long-axis strain and adjacent intraventricular pressure gradients were calculated and analyzed.Results ①Regional myocardial velocity and regional peak early diastolic inflow velocity in normal subjects declined from basal to apical segments gradually at the same ventricular wall (P ＜ 0.01).② Emax was correlated with emax(r =0.418,P ＜0.001),and E was correlated with Em (posterior septum,r =0.610,P ＜0.001 ；anterior wall,r =0.499,P ＜0.001).③There was a medium correlation between normal longaxis strain in segments and adjacent intraventricular pressure gradients (the global,r =0.412,P ＜0.001 ；posterior septum,r =0.319,P ＜0.005).Conclusions The acquirement of E and Em by dual-PW Doppler showed downtrend of segmental wall movement and regional blood flow from basal segment to apex.Emax is correlated with e E is correlated with Em,and long-axis strain at segments is correlated with adjacent intraventricular pressure gradients partly.Dual-PW Doppler might provide a potential method for the more precise evaluation of left ventricular fluid-solid coupling during diastole.
