OBJECTIVE:To observe clinical efficacy and safety of salmeterol and fluticasone propionate in the treatment of mod-erate and severe bronchial asthma. METHODS:98 patients with moderate and severe bronchial asthma were selected from our hospi-tal were included in the study and were randomly divided into control group(49 cases,3 cases withdrew from the test and 46 cases completed the test)and observation group(49 cases,2 cases withdrew from the test and 47 cases completed the test). Control group was given Budesonide aerosol preparation,1 dose,bid;observation group was given Salmeterol and fluticasone propionate inhala-tion,1 dose,bid. The treatment course lasted for 2 months. Clinical efficacy,lung function indexes,the time of clinical symptom disappearance,FEV1,PD20,ACT score,asthma attack times within half an year,EO%and ECP in serum and sputum,and the oc-currence of ADR were compared between 2 groups. RESULTS:After treatment,total effective rate of observation group was signifi-cantly higher than that of control group(95.73% vs. 76.09%);FVC,FEV1 and PEF and other indexes of 2 groups were increased significantly,and the observation group was significantly higher than the control group;the disappearance time of pulmonary rales, wheezing,dyspnea and cough in observation group were significantly shorter than in control group;PD20 and ACT score of 2 groups were significantly increased,ACT score of observation group was significantly higher than that of control group;EO% and ECP in serum and sputum of observation group were significantly lower than those of control group,there was statistical significance (P<0.05). Asthma attack times within half an year in observation was less than control group,there was no statistical significance (P>0.05). All ADRs disappeared after drug withdrawal. CONCLUSIONS:Therapeutic efficacy of salmeterol and fluticasone propio-nate is better than budesonide in the treatment of moderate and severe bronchial asthma,and can effectively improve lung function, shorten the time of clinical symptoms disapperance and reduce the level of inflammatory factor with and good safety.

OBJECTIVE:To compare the efficacy and safety of rosuvastatin and atorvastatin in the treatment of coronary heart disease. METHODS:96 patients with coronary heart disease were randomly divided into observation group and control group. All patients received reasonable diet control,low molecular weight heparin,Aspirin enteric-coated tablet,β-blockers,nitric acid lipids and other conventional treatment,but no vitamins and other antioxidant drugs. Based on it,observation group was orally given 10 mg Rosuvastatin tablet,once a day;control group was given 20 mg Atorvastatin capsule,once a day. The treatment course for both groups was 6 months. Clinical efficacy, total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol(HDL-C),high-sensitivity C-reactive protein(hs-CRP)and left ventricular ejection fraction (LVEF) before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:There were no significant differences in the total effective rate and incidence of adverse reactions between 2 groups(P>0.05). Before treat-ment,there were no significant differences in the TC,TG,LDL-C,HDL-C,hs-CRP and LVEF between 2 groups(P>0.05). After treatment,TC,TG,LDL-C,HDL-C and hs-CRP in 2 groups were significantly lower than before,and TC,LDL-C and hs-CRP in observation group were lower than control group,HDL-C and LVEF in 2 groups were significantly higher than before,and observa-tion group was higher than control group,the differences were statistically significant (P<0.05). CONCLUSIONS:Rosuvastatin and atorvastatin has similar efficacy and safety in the treatment of coronary heart disease,but rosuvastatin is superior to atorvastatin in terms of reducing lipid levels.

Objective To investigate and analyze the relative factors in elderly men with type 2 diabetes mellitus(T2DM)complicated with osteoporosis(OP),thus to provide guidance for prevention of OP complicated with T2DM in elderly men.Methods Dual X -ray absorptiometry determination of bone mineral density (BMD)of 67 cases of elderly men with diabetes,men were divided into OP group (n =32),NOP group (n =35).Then,we compared differences in body mass index(BMI),diabetes duration,fasting plasma glucose (FPG),glycosylated hemo-globin(HbA1c),patients'age,fasting insulin(FINS),insulin sensitivity index(ISI),quantitative of urinary albumin (ALb),quantitative of urinary protein in 24 hours and alkaliphosphatase level(ALP),low density lipoprotein choles-terin(LDL -C),triglyceride(TG),and made correlation analysis.Results Compared with those in NOP group,pa-tients in OP group had older age,longer disease course,smaller baric index,lower BMD,higher ALP,lower FINS,low-er ISI,higher HbA1c,higher quantitative of urinary protein in 24 hours and urinary albumin,higher LDL -C,which were significantly different (P <0.05);BMD of elderly men with T2DM was negatively correlated to patients'age, disease course,HbA1c,quantitative of urinary protein in 24 hours,ALb,ALP and LDL -C,but positively correlated to BMI,FINS and ISI.Conclusion Many factors,such as elderly,low body weight,long duration of the disease,high level of blood sugar,insulin dysfunction,low insulin sensitivity,high level of blood suger,insulin dysfunction,low insulin sensitivity,high serum alkalinephosphatase,high LDL -C and diabetic nephropathy,contribute to osteoporosis in elderly men with T2DM.

OBJECTIVETo compare clinical efficacy of individual osteotomy instrument and total knee arthrolplasty (TKA) in treating patients with knee osteoarthritis.

METHODSFrom June 2014 to December 2014, 40 patients with unilateral knee osteoarthritis were randomly divided into two groups and 20 cases were in each group. One group (individual group) were treated with TKA with individual osteotomy instrument,including 5 males and 15 females with an average age of (67.3 ± 6.5) years old; 8 cases on the left side and 12 cases on the right side. Another group (conventional group) were treated with conventional TKA , including 6 males and 14 females with an average age of (66.8 ± 7.3) years old; 9 cases on the left side and 11 cases on the right side. Operative time, blood loss, postoperative HSS score at 6 months, and changes of mechanical alignment before and after operation were analyzed.

RESULTSOperative time in individual group was (79.3 ± 4.7) min, and (83.5 ± 3.2) min in conventional group; blood loss in individual group was (287.1 ± 24.9) ml and (363.4 ± 47.2) ml in conventional group, there were statistical differences between two groups in these two items. There was no significant difference in postoperative HSS score at 6 months between individual group (84.8 ± 3.2) and conventional group (84.2 ± 2.5). Postoperative limb alignment in individual group was (2.8 ± 0.6)°, and (2.8 ± 0.6)° in conventional group, with no significant difference between two groups.

CONCLUSIONTKA with individual osteotomy instrument could reduce operative time and blood loss, but there was no differences in knee function, changes of mechanical alignment compared with TKA.

Objective To discuss the methods of the operative treatment for posterior tibial tendon dysfunction (PTTD). Methods From December 2002 to June 2005, 8 cases of PTTD were treated with operations, including 2 males and 6 females with an average age of 47 years (range, 36 to 56 years). Left side was involved in 6 cases, and right side was affected in 2 cases. Stage Ⅱposterior tibial tendon dysfunction were 2 feet and stage Ⅲ were 6 feet. Every case with special operative treatment, for instance lateral column lengthening, arthrodesis, repair posterior tibial tendon, spring ligament reefing, flexor digitorum longus tendon transfer and so on. Every bone operation was combined with one or more than one sofe tissue operation. Anterior transfer and strengthening of posterior tibial tendon were performed in 4 cases, spring ligament reefing in 2 cases, flexor digitorum longus tendon transfer in 4 cases. All patients were fixed with plaster cast at inversion position for 4-6 weeks, then changed to plaster splint fixing at neutral position for 4 weeks. Functions of ankle and foot were evaluated before and after operation. Results All patients were followed up for an average of 28 months(range, 12 to 40 months). According to Maryland foot score, 2 were fair and 6 were failure in preoperative, 4 were excellent, 3 were good and 1 was fair in postoperative. The total excellent and good rate was 87.5%.
