Objective To study the clinical efficacy of modified Liuwei Dihuang Decoction (LDD) combined with metformin plus atorvastatin for the treatment of type 2 diabetes mellitus (T2DM) complicated with hyperlipidemia. Methods A total of 120 cases of T2DM patients complicated with hyperlipidemia were randomly divided into study group (N=60) and control group (N=60), which were treated with LDD combined with metformin plus atorvastatin orally, and with oral use of metformin plus atorvastatin respectively. The course of treatment lasted for 12 weeks. Before and after treatment, we compared the blood levels of fasting blood glucose (FBG), 2-hour postprandial blood glucose(2hPG), glycosylated hemoglobin(HbA1C), total cholesterol(TC), triglyceride(TG), high-density lipoprotein cholesterol(HDL-C), and low-density lipoprotein cholesterol(LDL-C) in the two groups. After treatment, we evaluated the therapeutic effect of the two groups. Results (1) The total effective rate of the study group was 95.0％, and that of the control group was 83.3％, the effective rate of the study group being significantly higher than that of the control group (P < 0.05). (2) After treatment, the blood levels of FBG, 2hPG and HbA1C of both groups were significantly lower than pre-treatment levels (P <0.001), and the levels of FBG, 2hPG and HbA1C of the study group were significantly lower than those of the control group (P<0.05, P<0.01 or P<0.001). (3) After treatment, the TC, TG and LDL-C levels of both groups were significantly lower and HDL-C was higher than pre-treatment levels (P < 0.001); the levels of TC and TG levels of the study group were significantly lower and HDL-C was higher than those of the control group (P < 0.05 or P < 0.001). Conclusion LDD combined with metformin plus atorvastatin exerts certain effect for the treatment of T2DM complicated with hyperlipidemia, and is more effective than metformin or atorvastatin alone.

[Objective]To explore the effects on the distal femoral joint by high intraosseous pressure after blocking of proximal and middle femoral medullary cavity with bone cement.[Method]The rabbit model was established whose proximal and middle femoral medullary cavity of left side was infused with PMMA while the right side served as the control.Twenty-six rabbits were cavided randomly into 4 groups,8 for normal control group,the remained modeled rabbits were grouped according to the observing time-point into following groups:4th(T4),8th(T8) and 16th week(T16).The rabbits was killed to obtain the samples of distal femoral articular synovium,cartilage and the bone under cartilage.Then the structural changes of these tissues were observed by HE staining,toluidine blue staining,immunohistochemistry and transmission electron microscope.[Result](1)HE staining:the damage to articular cartilage,synovial tissue and the bone under cartilage aggravated with time.At the 16th week,it showed the articular cartilage was destructed,the bone structure was severely damaged with the synovial tissue proliferation and swelling.(2)Toluidine blue staining(16th week):all the layers of articular cartilage appeared loss of stain while the superficial layers were slightly loss of stain in control group.(3)Immunohistochemistry(16th week):①CollagenⅡ:the chondrocytes were positively stainned.②TGF-?1:chondrocytes stain was positive;the staining of articular synoviocytes appeared positive.(4)Transmission electron microscope:The lesions to articular chondrocytes and bone cells aggravated with time,part of which presented with necrosis and collapse at the 16th week.[Conclusion]The distal femoral intraosseous and intramedullary blood circulation is severely damaged after blocking of the proximal and middle femoral medullary cavity with bone cement,leading to continuous high intraosseous pressure.It makes the bone metabolism disordered in distal femur,which results degeneration and necrosis in distal femur,cartilage and synovial tissue.

0.05) except IP between T_4 and T_(16)(P0.05).the dynamic and static RBI showed the same change tendency.[Conclusion]The intraosseous and intramedullary blood circulation is severely damaged after blocking of the proximal and middle FMC with bone cement,it induces a long time high IP and a series of changes of blood flow at distal femur.

OBJECTIVE:To prepare domiphen bromide osmotic tablets,and to observe,analyze the mechanism of drug release.METHODS:Coating prescription was optimized by uniform design and the cumulative rates of drug release of different formulated preparations were measured,pharmaceutical features of domiphen bromide osmotic tablet and mechanism of drug release were studied.RESULTS:The dosage of PEG-400 and the coating membrane thickness all had an effect on drug release.The optimal coating technique was analyzed as 12%of PEG-400 and 10mg of coating.Spray speed,temperature and rotation speed did not affect releasing profiles.CONCLUSION:Improvement in formulation of coat of domiphen bromide osmotic tablet can result in drug release for 12h,whose mechanism includes diffusion and osmotic pump principle.

Objective To study the lung protection of ambroxol in general thoracic surgery perioperation for the elderly.Methods Totally 130 hospitalized patients aged (65.1±4.3) years in our hospital during general thoracic surgery were randomly divided into two groups:ambroxol intervention(2 mg/kg,intravenous drip,once/d) and control groups (n=65 for each).The incidenceof pulmonary complications,changes of blood gas analysis before and after surgery and time of hospitalization were compared between the groups.Results The incidence of pulmonary complications was significantly lower in ambroxol intervention group than in control group (9.23％ vs.24.62％,P＜0.05).Blood gas analysis results before and after surgery were improved in ambroxol intervention group[PaO2:(61.32±8.65) mm Hg,(95.07±13.62)mm Hg; PaCO2:(44.15±5.52)mm Hg,(37.28±4.06)mm Hg] as compared with control group[PaO2:(62.11 ± 8.83) mm Hg,(80.37±10.46)mm Hg; PaCO2:(44.39±5.17) mm Hg,(40.73±4.51)mm Hg] (t=3.61,3.75,both P＜0.05).The time of hospitalization was shorter in ambroxol intervention group than in control group [(12.14±0.29) d vs.(15.85±0.62)d,t=3.41,P=0.036].Conclusions Perioperative use of ambroxol in general thoracic surgery in the elderly is worthy of clinical application because of reduction of pulmonary complications and shortness of hospital stay.

The three batchs of drug tablets release pattern were in accord with zero order kinetics during 12 h. Conclusion This method is easy to produce and reaches initial devise request.

[Objective]To explore the clinical effect of the new stem-less total hip arthroplasty.[Method]Exposed the hip joint through posterior-exterior incision,dislocate the femoral head,clear away sick tissues inside joint,throw into the centric pin by guide of the centric localizer,repaired bone by machine of modeling bone,set the cup and fixed by centric screw and the screw of substantia spongiosa bone on trochanter major and trochanter minor of the femoral.The acetabulum prosthesis according to the traditional total hip arthroplasty were fixed.[Result]Nine cases were followed up for average 20 months,evaluated by Harris Score standard,excellent 5 cases,good 2 cases,fair 1 cases,poor 0 case,the rates of excellent and good is 88.89%.[Conclusion]Because of keeping entire neck and part head of the femur,biomechanics conduction and distribute of the stem-less hip of prosthesis achieves natural biomechanics state of the human body,the treatment effect of short-term is satisfying,the treatment effect of long-term will go on get observation in future.

Objective To explore the expression of aquaporin (AQP)-4 in white matter of spinal cord after spinal cord contusion (SCC). Methods 88 adult Sprague-Dawley rats were assigned randomly to sham operation group and SCC group. The model was established by Al-len's method. BBB sore was used to assess the motor function of rats. The relative expression of AQP-4 mRNA was determined by Q-PCR technique. The localization of AQP-4 was observed by immunohistochemistry. Results BBB score showed motor dysfunction in SCC group, and it increased 7 and 14 days after SCC (t>5.061, P<0.001). The level of AQP-4 mRNA decreased on the 1st and 3rd days (t>50.44, P<0.001), and increased on the 5th day (t=-3.968, P=0.001), and lasted until the 28th day (t=-4.227, P=0.001) compared with that on the 3rd day. The immunohistochemistry showed AQP-4 was located on the process of glial cell and vascular endothelial cells in white matter of spi-nal cord. Conclusion AQP-4 may play various roles at different stages in SCC.
