Chongqing Medicine 2013;(21):2468-2469
Objective To explore the impact of placenta polypeptide injection on fracture healing time and the incidence of infec-tion in patients with limb fractures .Methods 138 cases with limb fractures admitted to our hospital from February 2010 to Febru-ary 2012 were randomly divided into two groups ,and each group had 69 patients .The control group was given conventional treat-ment while the observation group was given placenta polypeptide injection on the basis of the conventional treatment .The bone healing time and infection rates were observed .Results The limbs fracture healing time of observation group was significantly shorter than that of control group (P<0 .05) .The infection rate of observation group (1 .45% ) was significantly lower than that of control group (10 .14% ,P<0 .05) .Conclusion The placenta polypeptide injection for treatment of limb fractures can effectively decrease fracture healing time ,and significantly reduce the rate of infection .

Journal of Applied Clinical Pediatrics 1992;0(05):-
Objective To study the inhibitive effect of interleukin-4(IL-4) and (or) IL-10 on cell apoptosis of renal ischemic-reperfusion injury(IRI) in rats and its mechanism.Methods Thirty female Sprague-Dawley rats were divided into five groups(n=6): sham-operated group,operation+9 g/L NaCl control (NaCl group),operation+IL-4(IL-4 group),operation+IL-10(IL-10 group),operation+ IL-4+IL-10 (IL-4+IL-10 group). The animal model of IRI was set up by clamping bilateral renal pedicles for 45 min.When the clamp was loosed, relevant agents was injected in every group. Apoptosis of renal epithelial cells (TUNEL method) was obserued.Results IL-4 could not reduce level of apoptosis of renal epithelial cells.To some extent,IL-10 could reduce level of renal epithelial cells. The combination of IL-4 and IL-10 was more effective in inhibiting apoptosis of renal epithelial cells.Conclusion The combination of IL-4 and IL-10 is effective in inhibiting apoptosis of renal epithelial cells, indicating that it has a relationship in preventing renal histological and functional damage.

[Objective]To study the mechanism of posterior longitudinal ligament in cervical spine through measuring the collagen and Proteoglycan and Calcium changes.[Method]Fifteen specimens of cervical longitudinal ligament from cervical spondylotic myelopathy(CSM)and ten control specimens from corpses without cervical spondylosis were obtained.The content of the collagen was measured by Weossner method.Collagen type Ⅰ and Ⅱ were measured by Enzyme-Linked Immunosorbentassay(ELISA)method.Phloroglucinol spectrophotometer to determine the change of amount of Proteoglycan.The Calcium by Methyl-Thymes-Blue(MTB)Colorimetric Method.The specimens were treated hy Hematoxylin and Eosin(HE)stain method and by Masson stain method,the pathological changes of two groups were observed through microscopy.[Result]In CSM,as compared to the control groups,there showed a decrease in the contents of the total Collagen,Collagen type Ⅰ and Proteoglycan,and increase in the content of collagen type Ⅱ.The rate of type Ⅰ/Ⅱ in CSM was lower than that in control groups.An increase in the content of the Calcium.All of which have statistic significance(P

The effects of cyanide poisoning on the contractibility of the cardiac muscle were observed after the dogs were infused intravenously with a lethal dose of NaCN (2.5 mg/kg) within 2 minutes through a cannulated femoral vein. Heart rate (HR) , left ventricular pressure (LVP) , the largest changing rate of LVP (LVP?dp/dtmax), cardiac muscle contractibility (CMC) , the largest changing rate of CMC (CMC?dc/dtmax) , and ECG changes were recorded. It was found that there was an initial excitatory response of cardiac functions in the first minute of NaCN infusion, and then a drastic cardiac failure occurred, which resulted in the rapid death of the dogs within 10 minutes after NaCN administration. The changes of myocardial contractibility were slower than those of .other cardiac parameters, which implies that cyanide can exert an excitation on the myocardium initially. Our results indicate that the effects of cyanide on myocardial contractibility may be one of the important factors to induce serious arrhythmia,which in turn results fatal cardiac failure.

Although allograft corneal transplantation has made great progress,keratoprothesis implantation is the only one hope, for both the patients who has fleshy pannus corneal vitiligo and the patients with the failure corneal transplantation surgery whose far sight is only light perceptions to recover their eye sight. To gain success and reduce complications, a lot of work has been done in keratoprosthesis materials and type, but heterogeneity and bio-compatibility are not solved totally. Because of development in the cell culture and tissue engineering, cornea ex vivo culture has gain a critical success. From cell option to carrier using, reconstructed three dimensional culture and epithelium equivalent mimicked human corneas in key morphology and function and were used in basic and clinical investigation. This article reviews the development of materials of keratoprosthesis and tissue engineering cornea.

OBJECTIVE To observe the therapeutic effectiveness and safety of the indigenous teicoplanin in intensive care unit(ICU) patients with severe infections of Gram-positive(G+) cocci.METHODS Sixty patients with severe Gram-positive bacteria infection received teicoplanin which was produced by Xinchang Pharmaceutical Factory of Zhejiang Medicine Co,Ltd.by infusion for 7-14 d.Dosage was adjusted according to the creatinine clearance rate.Maximum temperature,APACHEⅡ score,indicators of inflammatory response,liver and kidney function,microbiologic examination and adverse reactions were observed before treatment and the end of 7-14 day treatment.RESULTS Seventy-two strains of Gram-positive cocci were isolated from 60 patients,in which meticillin-resistant Staphylococcus aureus(MRSA),meticillin-resistant S.epidermidis(MRSE),Enterococcus faecium,E.faecalis,S.haemolyticus and E.gallinarum accounted for 58.33%,8.33%,16.67%,5.56%,8.33% and 2.78%,respectively.After treatment,59 strains of Gram-positive cocci were eliminated while 13 strains were not eliminated and bacteriological eliminated rate(calculated by strains) was 86.1%;In this group,twenty-eight patients were cured while twenty-two cases were markedly improved.The total bacteriological eliminated rate was 81.94%.The incidence of adverse reactions was low and only a slight increase or decrease in platelet count was observed which didn′t require special treatment interventions.CONCLUSIONS Indigenous teicoplanin has certain therapeutic effectiveness and is safe for severe Gram-positive bacteria infected patients,particularly for septic patients with organ damage in ICU.In patients highly suspected with meticillin-resistant staphylococci or enterococci infection,teicoplanin may be a choice for initial empirical treatment.
