Against the backdrop of ongoing healthcare system reform and escalating competitions among hospitals in China,more and more specialists and scholars on hospital administration begin to focus their studies on the theories and practice of hospital flows.Methodology frequently called into play in such study include out-patient flow refom,progressive flow improvement,and attention to management and service.Discussed in this paper are the advantages and disadvantages of these three methods as a reference for an appropriate choice by hospitals at large.

Objective To investigate the regulation of miR-1 and miR-133 a on L-type calcium channel β2 subunit ( Cavβ2 ) and α1C subunit during rat cardiomyocyte hypertrophy .Methods Cardiomyocyte hypertrophy was in-duced by isoproterenol (ISO, 10μmol/L).The targets of miR-1 and miR-133a were predicted by online database microCosm and Targetscan , respectively .The 3′untranslated region sequences of Cavβ2 andα1C were respectively cloned into reporter vector and then transiently transfected into HEK 293 cells.The luciferase activities of samples were measured for demonstrating the expression of luciferase reporter vector .The protein expression of Cavβ2 andα1C were evaluated by Western blot .The expression levels of Cavβ2 andα1C were inhibited by RNAi to determine theeffectsofCavβ2andα1Concardiomyocytehypertrophy.Results 1)Cavβ2wasoneofpotentialtargetsof miR-1,α1C was the one of potential targets of miR-133a.2) The luciferase activities of HEK293 cells with the plasmid containing widetype Cavβ2 3′UTR sequence or α1 C significantly decreased ( P <0.05 , P <0.01 ) . 3 ) Upregulation of the miR-1 and miR-133 a by miR-1 mimic and miR-133 a mimic transfection suppressed pro-tein expression of Cavβ2 and α1C, respectively(P<0.01, P<0.05).4)Downregulation of Cavβ2 andα1C by RNAi could markedly inhibit the increase of cell surface area ( P<0.01 ) , mRNA expression of ANP andβ-MHC (P<0.05).Conclusions Cavβ2 is the target gene of miR-1 and α1C is the target gene of miR-133a.miR-1 and miR-133a can negatively regulate the expression of L-type calcium channel Cavβ2 andα1C subunit, inhibi-ting cardiomyocyte hypertrophy.

BACKGROUND: The femoral intramedul ary guides in total knee arthroplasty require high precision, complex operation, it is very important for prosthesis and joint function to choose more precise positioning method and determine the correct needle point. OBJECTIVE: To study the effect of needle point position on prosthesis arrangement when applying different femoral intramedul ary guides methods in total knee arthroplasty. METHODS: Total y 80 patients who received the treatment of total knee arthroplasty in Changshu No.1 People’s Hospital from January 2012 to July 2015 were selected and divided into test and control groups according to random number table (n=40/group). The patients in the test group accepted CT scan for femoral intramedul ary guides. The theoretical position of femoral intramedul ary guides entry point was marked using radiographic parameters. In the control group, the traditional total knee arthroplasty technology was used to mark the entry point of femoral intramedul ary guides. The needle point position when applying different femoral intramedul ary guide methods was observed. The effect of femoral intramedul ary guides on prosthesis arrangement in total knee arthroplasty was discussed. RESULTS AND CONCLUSION: Compared with the control group, the distance from entry point to femoral anatomic line on positive and lateral X-ray film in the test group was shorter, femoral prosthesis lateral angle and physiological valgus angle were closer to the theoretical value, distance from intersection of femur axis and femoral condyle to block center was shorter; the differences were statistical y significant (P < 0.05). These results demonstrate that compared with the traditional two-dimensional intramedul ary positioning, the needle point position of three-dimensional CT scan stimulative positioning is more accurate. The location more concentrates on within intercondylar fossa 2-5 mm, more front of intercondylar fossa 3-10 mm, three-dimensional CT scan stimulative positioning is a reliable choice for femoral intramedul ary guides.

Objective:To investigate the effect of saw palmetto extract ( SR ) on GL261 glioma in rats and immune system.Methods:The 40 rats were divided into 4 groups randomly,one was the control group without tumor( the blank group) ( n=10) ,the other 30 rats were given subcutaneous inoculation of tumor cells and then divided into 3 groups:the tumor-bearing group( n=10) ,low dose SR group( n=10) ,and high dose SR group( n=10).After 1 week fed,the rats of SR groups were given the saw palmetto extract,low dose group 50 mg/kg once a day every other day and 300 mg/kg of high dose group every other day.The tumor-bearing groups received the same dose of distilled water.After 4 weeks fed, we measured the tumor weight and the inhibition rate was calculated.The tumor cell apoptosis was detected by TUNEL staining.The activity of splenic macrophages was detected by macrophage phagocytosis of chicken erythrocytes and CD4+lymphocytes by flow cytometry.Results:①The SR groups compared with tumor group, the tumor weight was significantly reduced(F=62.678,P=0.000).The tumor inhibition rate was significantly higher in high dose group.②The apoptosis of tumor cells in tumor-bearing group was significantly less than SR groups and the apoptosis was significantly increased after treatment with SR ,especially in high dose SR group(F=1.287,P=0.000).③Compared with the blank group,the macrophage activity decreased remarkablely.SR enhanced the macrophage activity obviously, positively related to doses of SR ( F=141.205,P=0.000;F=126.903,P=0.000).④In the tumor-bearing group,the CD4+lymphocyte count decreased significantly.After SR treatment,the CD4+lymphocyte increased and were positively related to the dose of SR.Conclusion: Saw palmetto extract can strengthen the immune system.

BACKGROUND:Total knee arthroplasty mainly used fixed platform, but more and more movable platform was selected year by year in the clinic. Rotary platform theoretical y can apparently improve the curative effects, but it has not been verified in the clinic.
OBJECTIVE:To summarize the design characteristics and clinical results of Gemini MKII (Link, Germany) rotary platform.
METHODS:From January 2004 to January 2009, 108 patients (119 knees) including 31 males and 77 females were treated with total knee arthroplasty by using Gemini MKII system. There were 97 unilateral cases and 11 bilateral cases at the first stage of replacement. Preoperative diagnosis:1 case of hemophilic arthritis, 1 case of venereal Charcot’s disease, 8 cases of post-traumatic arthritis, 11 cases of rheumatoid arthritis, and 87 cases of degenerative osteoarthritis. The prosthesis was fixed with bone cement. None received patel ar replacement. RESULTS AND CONCLUSION:None experienced infection, femoral condyle fracture or nerve and vascular damage. Except bilateral replacement, the average operation time of unilateral replacement was (56±13) minutes. Average postoperative hemoglobin decreased (25±5) g/L. After replacement, hemoglobin maintained over 100 g/L in 83 patients (86%), without blood transfusion. Knee joint score and function score recovered to (92.0±4.7) points and (90.3±6.8) points at half years after replacement, and became (94.4±3.2) points and (91.6±5.9) points during final fol ow-up, which was significantly improved as compared with that pre-replacement (P<0.01). No revision surgery should be done for lining prolapse or spin out, osteolysis and prosthesis loosening. These results indicated that the early and midterm results of Gemini MKII rotating-platform prosthesis were satisfactory, but the long-term results remain to be confirmed.

This article was aimed to study the acute toxicities on intragastric administration of differentRadix Aconiti Lateralis Praeparataprocessed products to Beagle dogs. A total of 16 healthy and qualified Beagle dogs were randomly divided into the blank group,Pao-Fu-Pian(PFP) group,Pao-Tian-Xiong(PTX) group andHei-Shun-Pian(HSP) group according to the body weight. The intragastric administration of 4 g crude herb per kg was given. Before medication, 1 h, 24 h, and 3, 7, 14 days after medication, the body weight, food consumption, rectal temperature, electrocardiogram, blood routine and blood biochemistry were measured. The results showed that after medication, all dogs in three experimental groups were depressed. And there were significant differences in the electrolytes of blood. Among them, the HSP group was the most obvious one. The red blood cells, blood sugar and triglycerides of dogs in the PFP group had significant difference. The lymphocytes and blood sugar had significant difference of dogs in the PTX group. However, after the medication of HSP, the lymphocytes of the dogs were decreased significantly. It was concluded that the toxicity of three processed products followed the order of HSP > PFP > PTX.
