Objective To study the possibility and effect of application of clinical pathways (CP) in patients with lumbar vertebrae protrusion undergoing resection of nucleus pulposus. Methods 280 patients with lumbar vertebrae protrusion undergoing resection of nucleus pulposus were selected and divided into the experimental group and the control group randomly. Each group had 140 cases. Clinical pathways was applied to the experimental group, while traditional nursing method was given to the control group. Treatment and nursing effect were compared between the two groups. Results The cost for hospitalization was lower, hospitalization time was shorter, the first time for functional exercise after operation was advanced and satisfaction degree of patients was increased in the experimental group compared with those of the control group. Conclusions Application of clinical pathway in patients with lumbar vertebrae protrusion undergoing resection of nucleus pulposus played a positive and effective role.

Objective To study the prevention of pressure ulcer for bed-ridden patients by simple turn-over pillow and turn-over mattress.Methods Self-made simple turn-over pillow and turnover mattress were used in 1300 patients who had high risk of pressure ulcer,and the application effect was observed.Results No pressure ulcer occurred in 1300 patients when they were discharged.Conclusions Simple turn-over pillow and turn-over mattress showed definite effect to prevent pressure ulcer,they have application value,and are worthy of wide spread.

Objective To investigate effects of sevoflurane and propofol on hemodynamic changes in patients undergoing cardiac double valve replacement.Methods Totally 80 patients admitted with rheumatic heart disease were divided into sevoflurane group and propofol groups.The anesthetic drugs on hemodynamics,myocardial function and renal function were compared.Results There were statistically significant in CIL concentration,stroke volume index (SVI)and left ventricular -stroke work index (LVSWI)levels between the two groups at the same time points (F =2.467,2.4783,2.553,P =0.032,0.032,0.021).The levels of MAP,HR,PAWP,CIL,SVI and LVSWITBIL between the two groups were statistically significant at different time points (F =2.597,2.468,2.523,2.589,2.532, 2.556,P =0.032,0.021,0.030,0.021,0.024,0.023),and difference at the same group at different time points (F =2.597,2.468,2.523,2.497,2.479,2.538,P =0.032,0.021,0.030,0.034,0.034,0.038).No obvious liver and renal function damage was found during the surgery in the two groups.Conclusion Anesthesia induction of sevoflurane and propofol for patients undergoing cardiac double valve replacement has similar effects on the hemody-namics and cardiac function,without obvious damage to liver and renal function.

Objective:To culture mesenchymal progenitor cells(MPC)from compact bone fragments in C57 mice in vitro and to study the feasibility of inducing directed differentiation of MPC into neuron-like cells in vitro. Methods:Bones of hind limbs of C57 mice were sheared into bone fragments and digested by collagenase type Ⅱ. Then,MPC were cultured in vitro and analyzed by flow cytometry for identification of its immunology phenotype. MPC of P3 in good growth were induced directionally by the supernatant cultured with primary neuron,and then detected the expression of neuronal specific markers neuron specific enolase(NSE)and neurofilament protein(NF)by immunocytochemical staining. Results:The primary MPC were cultured successfully and they grewwell after passage. Compared with that of the control group,the positive rate of CD29 and CD44 of MPC of antibody group had significant difference (P

Objective:To prepare levofloxacin-carboxymethyl-chitosan(LVFX/CMC) microspheres and to study their colon-targeted release in rats.Methods: KromasilRKR100-5C18(250 mm?4.6 mm)was used as the analytical column and the temperature was maintained at 50℃.The mobile phase consisted of a mixture of acetonitrile:0.1% trifluoroacetic acid(2080) pumped at a flow rate of 1.0 ml/min,with ?_(ex)295 nm and ?_(em)495 nm.Sixty healthy male SD rats were randomized into 2 groups: to receive gastric lavage with normal LVFX(40 mg,control group) and LVFX/CMC microspheres(40 mg,treatment group).HPLC was used to detect the concentrations of LVFX in the stomach,intestine,cecum,colon and blood in rats in both groups.Results: LVFX was detectable 3 h after LVFX/CMC microsphere lavage.Five hours after lavage,the levels of LVFX in cecum and colon were respectively(3.394?0.197) mg and(1.873?0.216) mg in treatment group,and(0.489?0.123) mg and((0.078?0.002)) mg in control group(P

Usher syndrome (USH) is the most common syndromic retinitis pigmentosa (RP),which is an autosomal recessive disorder.RP is highly clinically and genetically heterogeneous.A total of 12 loci including nine genes have been identifiedas causing various clinical subtypes of USH.The USH2A gene is thought to be involved in the pathogenesis of most USH2 cases.Moreover,mutations of the USH2A gene is also responsible for atypical USH and nonsyndromic retinitis pigmentosa.Some studies found that the mutation spectrum among Chinese RP patients might differ from European Caucasians.Herein,the further survey should be performed to ascertain the hot gene mutation spectrum.

Objective:To evaluate the influence of health education on knowledge and attitude about drugs and addictive drug abuse prevention among the junior middle school students.Methods:389 junior middle school students were selected in this program.Drugs and addictive drug abuse prevention related knowledge and attitude of the junior middle school students were surveyed by questionnaire anonymously before and after the health education.Results:After education,average score of drugs and addictive drug abuse prevention knowledge among the junior middle school students was significantly increased from 8.8 to 15.7(full score 17),suggesting the significant difference.The junior middle school student's level of knowledge about the danger of smoking and drinking also increased significantly.The correct rate of the answers rose from 4.6%～78.6% to 79.4%～100.0%.After this education,the rate of correct attitude about the drugs and addictive drug abuse prevention was significantly higher than before.Conclusion:The study suggests that health education on drugs and addictive drug abuse prevention among the junior middle school students has the positive impact on increasing the basic knowledge on the drugs and addictive drug abuse prevention for the junior middle school students as well as setting up the correct attitude on it.

OBJECTIVE:To evaluate the cost-effectiveness of salmeterol/fluticasone compound(SFC)and budesonide(BUD)in the treatment of asthma.METHODS:A multicenter randomized controlled clinical trial was performed on386asthma cases,who were administered with SFC50/100?g bid or BUD400?g bid,data on which were retrospectively collected and then the cost-effectiveness analysis was conducted,the effectiveness was measured in terms of successfully-treated weeks,symptom-free days and uninvolved days;The direct healthcare cost was adopted as the cost index.RESULTS:The average daily medical cost of the SFC treatment group(RMB:15.6yuan)was a little bit higher than that of the BUD control group(RMB:13.8yuan),but the costs of every successfully-treated week,every symptom-free day and every uninvolved day for SFC group were166.5yuan,33.4yuan and41.2yuan,respectively,which were all lower than those of the BUD group(which were188.6yuan,50.6yuan and66.1yuan,respectively);Incremental cost-effectiveness ratios for every successful?ly-treated week,per symptom-free day and per uninvolved day for the SFC group were88.7yuan,9.4yuan and10.8yuan,respectively vs.the BUD group.CONCLUSION:The results show that the cost-effectiveness of SFC50/100?g bid is supe?rior to BUD400?g bid in the treatment of asthma.

OBJECTIVE:To provide the pharmacoeconomics referance for the medical reform implementation in China.METHODS:The relevant literatures at home and abroad combined with knowledge of pharmacoeconomics were to introduce and analyze the experience of pharmacoeconomics application at home and abroad.RESULTS & CONCLUSION:The pharmacoeconomics is involved in various related areas of drugs,and provides a scientific basis for drug pricing,reimbursement and other links.China should be based on international experience,combined with its national conditions to promote the development of pharmacoeconomics in order to effectively control the unreasonable increase in drug expenses,so that people really can "control it,use it,and afford it".
