Constructivism educational theory can provide a useful guidelines for health law education,this article finds the association of constructivist theory for health law education reform,and combined the with application of relevant theories on teaching practice experience,it also discusses how to provide a real promotion for the"students'first"concept.

Simulated teaching method is a necessary complement to theoretical teaching of health law,which meets the practical-oriented reform need and cultivates students with the literacy as a legal professional.The teaching method demands more requirements on teachers,students,teaching materials,organizational management,and more attention on contextual design,preparation details,implementation activities and evaluation of teaching.

Objective To compare the effect and safety of propofol with intranasal dexmedetomidine in analgesic enteroscopy for children.Methods Ninety children undergoing analgesic enteroscopy were ran-domly assigned to 3 groups.Intranasal dexmedetomidine followed by propofol was administered in the observ-ing group;sufentanil and followed by propofol was intravenously given to the control group A;propofol was given to the control group B.The scale of anesthetic effect,HR,RR,MAP and SpO2 30 min after intranasal administration were monitored.The intranasal sedation satisfaction rate,the dose of propofol,wake-up time, hospitalization,hemodynamics,adverse reaction and complication after anesthesia were recorded.Results Intranasal sedation satisfaction rate of the observing group was 83.3%(25 /30).The anesthetic effect in ob-serving group(excellent/good /bad:24 /6 /0)showed no significant difference from that in the control group A (excellent/good /bad:25 /5 /0),but better than that in the control group B(excellent/good /bad:12 /14 /4) (P <0.05).The amount of propofol in the observing group(96.2 ±5.3)mg showed no significant difference from that of group A(93.7 ±4.6)mg,but less than group B[(121.1 ±4.9)mg,P <0.05].The time of re-covery of infants in the control group A[(14.2 ±5.5)min]and the control group B[(13.7 ±3.9)min] were longer than that in observing group[(7.9 ±4.1)min,P <0.05].The hospitalization time of observing group[(14.3 ±5.4)min]was shorter than those of group A[(27.5 ±3.7)min,P <0.05]and group B [(26.3 ±6.6)min,P <0.05].The incidences of breath suppression,glossoptosis,nausea and dizziness were the lowest in the observing group,compared with the two others (all P <0.05).Conclusion In-tranasal dexmedetomidine combined with propofol,increasing children compliance,decreasing the adverse reaction,is satisfactory and safe for children anesthesia.

OBJECTIVE:To investigate clinical efficacy and safety of conjugeted estrogen tablets combined with Salmon calci-tonin acetate injection and Alendronate sodium tablets in the treatment of osteoporosis in postmenopausal. METHODS:148 post-menopausal women with osteoporosis were randomly divided into observation group(78 cases)and control group(70 cases). Con-trol group was given Salmon calcitonin acetate injection hypodermically or intramuscularly,100 IU each time,once a day in first week,every two days in second week,every three days in third week,21 times of consecutive injection as a treatment course;Alendronate sodium tablet,70 mg each time,once a week,3 months as a treatment course. Based on control group,observation group was additionally given conjugeted estrogen tablets,0.625 mg each time,qd,for consecutive 3 weeks,drug withdrawal for one week,and then continued to taking drug,for 3 months in total. Clinical efficacy of 2 groups were observed as well as BGP, bone metabolism index as human collagen type Ⅰ N-terminal peptide (NTX) and ALP,bone density and ADR before and after treatment. RESULTS:After treatment,total effective rate of observation group was 94.87%,which was significantly higher than 78.57% in control group,with statistical significance(P<0.05);BGP,lumbar spine and thigh-bone density of 2 groups were all improved significantly,and the improvement of observation group was more significant than that of control group,with statistical significance (P<0.05). NTX and ALP of 2 groups were decreased significantly,and the decrease of observation group was more significant than that of control group,with statistical significance (P<0.05). The incidence of ADR was 12.82% in observation group and 8.57% in control group,without statistical significance (P>0.05);various ADR disappeared after drug withdrawal. CONCLUSIONS:Conjugeted estrogen tablets combined with Salmon calcitonin acetate injection and Alendronate sodium tablets can effectively relieve bone pain,regulate bone metabolism,increase bone density and induce slight ADR in postmenopausal with osteoporosis.

Objective To observe the renal expression of cyclooxygenase-2 (COX-2) in rats with type 2 diabetes, and explore the effect of selective COX-2 inhibitor Mobic on the expression of renal COX-2, matrix metalloproteinase-9(MMP-9), tissue inhibitor of matrix metalloproteinase-1(TIMP-1), TXB 2 and 6-Ket-PGF1?, as well as renal structure and function. Methods All rats were divided into control group, diabetes mellitus group and treatment group. Type 2 diabetic rats were treated with Mobic and vehicle respectively. Immunohistochemistry was used to detect the expression of COX-2,MMP-9 and TIMP-1 in renal tissues. The urinary TXB 2 and 6-Ket-PGF1? concentration was determined by radioimmunoassay at 6th week. Results There were an increasing expression of COX-2, TIMP-1 and decreasing MMP-9 expression in the renal tissue of type 2 diabetic rats. Mobic could increase MMP-9 expression and depress TIMP-1 expression througth inhibiting the expression of COX-2 in the renal tissues of type 2 diabetic rats. Conclusion COX-2 was involved in the pathogenesis of type 2 diabetic nephropathy. Selective COX-2 inhibitor Mobic might exert its renoprotective effects through inhibiting COX-2 activity, decreasing prostagladins systhesis, and modulating MMP-9 and TIMP-1 expression.
