Objective To estimate the clinical efficacy of naloxone and trimetazidine in the treatment of severe viral myocarditis.Methods40 patients with severe viral myocarditis were randomly divided into two groups: control group(20cases) and treatment group(20 cases).All patients in control group and treatment group received conventional therapy.In adition,the patients in treatment group received naloxone and trimetazidine treatment.After 14 days,the changes of clinical symptoms were observed.In addition,serum creatinine kinase(CK)-MB and cardiac troponin I(cTnI) levels were measured.ResultsAlthough the symptoms,CK-MB and cTnI were significantly improved in two groups,but significant difference was still found between control group and treatment group(P

OBJECTIVETo investigate the applications of percutaneous screw fixation for the treatment of pelvic fractures and its related surgical considerations.

METHODSFrom June 2010 to June 2012,19 patients with pelvic fractures were treated with percutaneous hollow screws. There were 13 males and 6 females, with an average age of 41 years (ranged from 22 to 58 years). Fractures were caused by traffic accidents in 11 cases, by falling down from high place in 8 cases. Based on the Tile classification, there were 15 cases of Tile C type and 4 case of Tile B type. The indexes such as screw inserting time, intraoperative blood loss, complications, functional recovery and reduction conditions were observed. Fixation methods included sacroiliac screws, cannulated screw fixation of the pubic ramus and cannulated screw fixation of the pubic symphysis separation.

RESULTSAnatomical reduction achieved in 7 cases, satisfactory reduction 11 cases, and unsatisfactory reduction 1 case. Union time of fracture union ranged from 8 to 12 weeks (mean 10 weeks). Wound infection,ununion of fracture and nerve injuries were not found. According to the Majeed standards, 12 patients obtained an excellent results, 6 good and 1 fair.

CONCLUSIONPercutaneous screw fixation for the treatment of pelvic fractures under fluoroscopy has several advantages such as less trauma, less blood loss, fewer rates of complications, reliable fixation and no blood transfusion, which can reconstruct the stability of the pelvic ring, but it needs adequate preoperative preparation and high requirements for the surgeon.

Objective To explore the risk factors of severe pneumonia caused by multi-drug resistant Klebsiella pneumonia,and antimicrobial drug resistance among these isolates.It may help to prevent and control the disease and promote to rational use of antibiotics.Methods We conducted the case-control study in our PICU.It included 89 patients with severe pneumonia caused by multi-drug resistant Klebsiella pneumonia as case group and 68 patients with severe pneumonia caused by Klebsiella pneumonia as control group during the same period.To compare the two groups on irrationality use of antibiotics (especial for third generation cephalosporin),length of stay,tracheal cannula,time of mechanical ventilation and underlying conditions (malnutrition,congenital heart disease,heredity and metabolic disease).Antimicrobial susceptibilities among 89 multi-drug resistant Klebsiella pneumonia isolates were analyzed.Results There were 63 cases (70.79％) for irrationality use antibiotics in case group,while there were 27 cases (39.70％) in control group (P ＜ 0.01).The cases for length of stay over 7 days in case group (48 cases,53.93％) were more than those cases with the same situation in control group (12 cases,17.65 ％) (P ＜ 0.01).Thirty-eight cases (42.69 ％) needed mechanical ventilation therapy in case group,while 16 cases (23.53％) needed mechanical ventilation therapy in control group (P ＜ 0.01).The cases for duration of mechanical ventilation over 5 days in case group (18 cases,20.22％) were more than those cases in control group (5 cases,7.35％) (P ＜0.05).The cases with underlying disease in case group (13 cases,14.61％) were more than those cases in control group (2 cases,2.94％) (P ＜ 0.05).Multi-drug resistant Klebsiella pneumonia isolates demonstrated that high-level resistance for penicillins,cephalosporins,aminoglycosides and quinolones,but still susceptible to carbapenems.Conclusion Several risk factors are associated with severe pneumonia caused by multi-drug resistant Klebsiella pneumonia,including irrational use of antibiotics (especial for third generation cephalosporin),long term of length of stay,endotracheal intubation,long term of mechanical ventilation,and having underlying disease (malnutrition,congenital heart disease,heredity and metabolic disease).Multi-drug resistant Klebsiella pneumonia isolates demonstrated that high-level resistance for penicillins,cephalosporins,aminoglycosides and quinolones,but still susceptible to Carbapenems.Carbapenems should be used as first-line drugs for severe pneumonia caused by multi-drug resistant Klebsiella pneumonia.

Objective To investigate the mechanism of radiosensitization by cetuximab (C225) on human tongue cancer Tca8113 cell line in vitro.Methods Tca8113 cell line with and without C225 treatment received 6 MV X-ray irradiation of different doses (0, 2,4,6, 8 and 10 Gy). Cell proliferation,cell-cycle distribution and clonogenic survival were analyzed through cell counting,MTT,colony formation assay,and flow cytometry,respectively.Results After irradiation of different doses,the growth inhibition rates in C225 group were higher than control (t =- 15.6 - -3.0,P＜0.05),the radiobiological parameters (D0,Dq,N,and SF2 ) in C225 group were lower than control so that SER of C225 group was 1.353,and the proportions of G0/G1 cells in C225 group were higher than control ( t =-7.64,-7.89,-4.78,P ＜0.05 ) at 4,6,8 Gy.When the irradiation doses increased,the early phase apoptosis in both groups increased at first and then decreased with the maximum difference at 4 Gy [(7.96±0.36)％ in C225 group and (4.13 ±0.29)％ in control group,t =-12.75,P＜0.01 ].Conclusions C225 has radiosensitization effect on Tca8113 cell line,possible through Go/G1 arrest and induction of apoptosia.

Objective To evaluate regional airway obstruction with balloon catheter in stabilizing the vital signs in experimental animals suffered from acute massive pulmonary embolism. Methods Pulmonary embolism of right lung artery by using auto-blood clots or detachable latex balloons was established in 27 healthy sheep. When the blood oxygen saturation decreased by 25% compared to that before the procedure,the placement of balloon catheter in corresponding right main bronchus was carried out in 18 sheep (study group). Five sheep were used as control group. The blood oxygen saturation in the remaining four sheep did not reach the intervention level. The pulmonary arterial pressure, the peripheral arterial pressure, the central venous pressure, the heart rate, the blood oxygen saturation, the arterial partial pressure of oxygen as well as of carbon dioxide were invasively determined. Results The experimental model of acute massive pulmonary embolism was successfully established in 23 sheep. After the establishment of pulmonary embolism, increased heart rate, tachypnea, a decrease of ≥ 25% in blood oxygen saturation within 30 minutes and a rise in pulmonary arterial pressure were detected. After the placement of balloon catheter in study group, a reduction of the pulmonary arterial pressure and an elevation of the blood oxygen saturation as well as the arterial partial pressure of oxygen rose. were observed. The difference between study group and control group was statistically significant (P < 0.05). Conclusion The result of this animal experiment indicates that obstruction of airway with balloon can be served as a first aid for acute massive pulmonary embolism, which can stabilizes the animal's vital signs and, therefore, can help gain precious time for the follow-up thrombolysis treatment.

Objective　To investigate the effects of glucagon-like peptide 2 (GLP-2) on recovery of small intestinal epithelia from radiation injury in mice. Methods　Mice received a single 8 Gy dose of total body irradiation from 60Co gamma ray followed by treatment with GLP-2 or vehicle. DNA and protein content in small intestinal mucosa were measured, and small intestine was processed for histological examination with light microscope and scanning electron microscope. Results　Small intestinal mucosal DNA and protein content, villus height, and villus number significantly decreased in irradiated mice, partial villus tips were ulcerated. GLP-2 administration caused increase in DNA and protein content, villus height, and villus number as compared with irradiated control group. Meanwhile, the villus tips were lack of ulceration. Conclusion　GLP-2 can promote recovery of small intestinal epithelia from radiation injury in mice.

Objective　To study the effect of glucagon-like peptide 2 (GLP-2) on mitogen-activated protein kinase (MAPK) activity in small intestinal epithelia in mice after radiation injury and its relation with the change of small intestinal epithelial proliferation. Methods　Mice were given a single dose of 8 Gy of total body 60Co gamma irradiation and then divided into GLP-2 and control groups. The activity of MAPK and proliferation rate in small intestinal epithelia were measured. Results　The activity of MAPK in small intestinal epithelia was higher in GLP-2-treated mice than in irradiated mice, and the proliferation rate in small intestinal epithelia significantly increased in GLP-2-treated mice. These two indices were of significantly positive correlated. Conclusion　GLP-2 can promote small intestinal epithelial proliferation in irradiated mice, and this may be related to activation of MAPK in small intestinal epithelia.
