Objective:To evaluate the impact of atorvastatin and rosuvastatin at different doses on liver function in the patients with coronary artery disease. Methods:A retrospective study was used, and the patients with coronary heart disease hospitalized in the first hospital of China medical university from January 2013 to March 2014 were selected. According to the drug variety and dosage, the patients were divided into four groups: A (atorvastatin, 20 mg·d-1), B (atorvastatin, 40 mg·d-1), C (rosuvastatin, 10 mg· d-1 ) and D ( rosuvastatin, 20 mg·d-1 ) . The basic information of patients, the indices of liver function( ALT,AST,ALP and TBIL) , the time of abnormal liver function, treatment strategies and prognosis were recorded. The incidence of abnormal liver function in the groups was compared, and the rationality and effectiveness of the intervetion strategies were evaluated. Results:A total of 269 patients were collected. Among them, 149 cases were with abnormal liver function in varying degrees, and 21 patients were with ALT>3?ULN. The incidence of ALT>3?ULN in atorvastatin high dose group was much higher than that in atorvastatin low dose group( P<0. 05). Conclusion:The patients treated with high dose atorvastatin (40 mg·d-1) have a high risk of liver injury.

OBJECTIVETo explore the therapeutic efficacy of unilateral multiple channels approach in percutaneous vertebroplasty (PVP) for osteoporotic vertebral fractures.

METHODSA retrospective review (from March 2003 to October 2012) was conducted on 685 consecutive patients, a total of 885 vertebrae were involved. Eighty-two cases (99 vertebrae) with bone cement leakage when less than 0.3 ml bone cement was injected to fill the fracture were given PVP procedure by unilateral multiple channels approach. 38 cases were male (45 vertebrae) and 44 cases were female (54 vertebrae). The average age was 75.4 years old (from 69 to 92). The operation time, amount of injected bone cement and complications were recorded. Rate of excellent and good outcomes was studied by measuring the cement distribution on the X-ray film. The visual analogue scale (VAS) score and Oswestry disability index (ODI) system were used to evaluate the pain relief and improvement of daily activity function respectively at preoperation and 1 hour, 1 month, 3 months and 6 months after operation.

RESULTSAll these ninety-nine vertebrae were treated in 82 cases with PVP of unilateral multiple channels approach. The average operation time was 33 minutes. The rate of excellent and good outcomes of cement distribution was 98.8%. The VAS score was (8.40 +/- 0.73) before surgery,and (2.50 +/- 0.43), (2.00 +/- 0.33), (1.80 +/- 0.28), (2.10 +/- 0.17) at 1 hour, 1 month,3 months and 6 months respectively after operation. ODI was (40.94 +/- 2.72) before surgery, (9.64 +/- 2.60) at 1 month after surgery, (8.52 +/- 2.30) at 3 months after surgery and (7.77 +/- 2.15) at the final follow-up. The differences of the VAS and ODI between pre-operation and post-operation had statistical significance (P<0.01). No spine or nerve injuries occurred intraoperatively.

CONCLUSIONThe unilateral multiple channels approach in percutaneous vertebroplasty can obviously relieve the pain and effectively improve the functional activity, provide a satisfied cement distribution in vertebral body with cement leakage after a small amount infusion.

Objective To investigate the effects of different anesthesia methods on oxidative stress in elderly patients undergoing neurosurgery.Methods Totally 60 patients undergoing neurosurgery were randomly divided into 3 groups:propofol group,isoflurane group and sevoflurane group (n-20 each group),heart rate(HR) and mean artery pressure(MAP) in all patients were recorded at the time points of pre anesthesia (T0),incision of skin (T1),incision of dura (T2),end of operation (T3).The activity of superoxide dismuase (SOD),catalase (CAT),and glutathione peroxidase (GSH-Px) were measured at the time of T0,6 h (T4),24 h (T5),48 h (T6),72 h (T7)after operation.The efficacy of anesthesia was evaluated by Glasgow Outcome Score (GOS) at 3 months after operation.Results The activity of SOD,CAT and GSH Px in 3 groups were lower at T5and T6 than at T0 (P＜0.05).The SOD activity at T4,T5,T5and TTwere higher in propofol group [(87.2±11.8) U/ml,(75.1±12.4) U/ml,(84.6±9.3) U/ml,(92.5±12.5) U/ml,respectively]than in isoflurane group [(75.0±12.2) U/ml,(63.8±8.9) U/ml,(70.3±9.0) U/ml,(82.5±13.5) U/ml,respectively] and in sevoflurane group [(79.4±10.4) U/ml,(68.7±10.5) U/ml,(72.0±10.9) U/ml,(85.17±8.41) U/ml,respectively] (all P＜0.05).The CAT activity at T5 was higher in propofol group [(66.59±7.21) U/ml] than in isaflurane group [(51.58±8.19) U/ml] and in sevoflurane group [(58.49±7.27) U/ml] (both P＜0.05).The GSH-Px activity was higher at T4,T5and T6 in group propofol[(159.2 ± 20.8) U,(140.7 ± 16.2) U,(152.3 ± 19.1) U,respectively] than in isoflurane group [(129.4±17.9) U,(108.3±15.9) U,(118.4±14.1) U,respectively] and in sevoflurane group [(140.1±15.8) U,(125.2± 17.1) U,(137.9±10.7) U,respectively] (all P＜0.05).The outcome of neurosurgery had no significant differences among the 3 groups (P＞0.05).Conclusions Propofol has a better effect on oxidative stress than isoflurane and sevoflurane in elderly patients undergoing neurosurgery.

BACKGROUND:Closed reduction and interlocking intramedullary nailing can protect blood supply of fractured bone,decrease infection and promote bone healing.which is becoming the first choice for treating femoral shaft fracture However,it is difficult to conduct in closed reduction and keep stabilization of fractured bone.OBJECTIVE:To explore the curative effect of closed reduction and interlocking intramedullary nailing in treating femoral shaft fracture with assist of rubber tourniquet 360°elastic fixation METHODS:From May 2008 to November 2009,18 patients(14 males,4 females;aged 18-65 years)with closed femoral shaft fracture were treated at the Dongguan Hospital of Traditional Chinese Medicine.Body skin was protected by cloth,elastic rubber tourniquet was doubled and 360°wrapped around the fractured bone with the length of 10 cm from up and down.Supracondylar femur was reamed by Kernig-needle;fractured bone was dealt with countertraction and horizontal rotation.Another assistant compressed the fractured bone according to the displacement of fracture,which contributes to bone fracture reduetion and interlocking intramedullary nailing.RESULTS AND CONCLUSION:All 18 patients were followed up postoperatively,no case was found with skim necrosis and damage of nerve and blood vessel.16 cases were bone union with excellent 15 cases,fine 1 case;2 cases were still being followed up.Callus was firstly found 1 month after operation and was obviously found in 3e months postoperatively The result suggested that the treatment of closed reduction and interlocking intramedullary nailing with assist of rubber tourniquet360°elastic fixation is a simple and applicable approach.which reduces the interruption of blood supply for fractured bone and closed reduction gets good result,which reduces the chance of open reduction.

Objeetive To investigate the changes of kidney cortex hemoperfusion before and after extracorporeal shock wave lithotripsy (ESWL) with contrast-enhanced ultrasonography (CEUS) and time-intensity curve.Methods Thirty patients of renal calculi were treated with ESWL and examined with CEUS before and after ESWL.Renal cortex blood perfusion parameters of the lithotriptic areas,including the contrast agent arrival time (AT) ,time to peak (TTP) .peak intensity (PI) and velocity parameters (β) were quantitatively measured with ACQ software.Results The value of AT,TTP and β were not significantly different before and after ESWL (P＞0.05) .PI value after ESWL was lower than that before ESWL (P＜0.05) . Conclusion CEUS can quantitatively evaluate the changes of kidney cortex hemoperfusion after ESWL,and reflect the minor renal damage resulted from ESWL.CEUS can be used as a new method of observing and evaluating the renal damage caused by ESWL.

Objective:To evaluate the effect of vacuum disk(VD) for non-invasive treatment of recurrent and acquired pectus excavatum(PE).Methods:From June 2017 to June 2019, 29 patients recruited from our outpatient clinic were included in this retrospective study and followed-up every 3 month according to the schedule. The patients were distributed into three groups(group 1 treated ≤6 months; group 2 treated from 6 months to 12 months; group 3 treated >12 months). The device should be applied regularly for more than 2 hours daily. The deformity chest wall was scanned by three-dimensional(3D)scanner at clinic, and the 3D-depth(3D-DE) and 3D-Haller index(3D-HI) of PE were calculated through Geomagic software.Results:In this cohort, 29 patients were eligible, 18 symmetrical PE and 11 asymmetric PE. The application time ranged from 3 months to 15 months(average 7.6 months). 4 paitents was lifted to a normal level, 23 patients were differently improved. However, 2 paitents had no improvement. The average of the depth and 3D-HI of all patients were improved from 17.7 mm to 11.6 mm and 1.739 to 1.598, respectively. It’s no statistically significant difference for the elevation of 3D-DE and 3D-HI between symmetrical and asymmetric PE( t=-2.821, P=0.558; t=0.074, P=0.068). When comparing the improvement of 3D-DE or 3D-HI of PE to the patient's treatment time, a statistically significant difference was proved between the group 2 and group 1( t=-2.261, P=0.014; t=-0.436, P=0.043), but not between the group 3 and group 2( t=-1.240, P=0.139; t=0.622, P=0.568). The main side effects include moderate subcutaneous hematoma(84%), petechial bleeding(27%), thoracalgia(32%) and chest tightness(17%), no other side effect appear till now. Conclusion:VD for treatment of recurrent and acquired PE is convenient, safe and noninvasive, which can be an alternative treatment for recurrent and acquired PE, However, long term of efficacy evaluation is still needed.

Objective To explore the sonographic characteristics and to evaluate its diagnostic value of hepatic lymphoma (HL). Methods The clinical data and abdominal sonographic ifndings of 18 consecutive patients with histological proven diagnosis of lymphoma with liver involvement were reviewed, including contrast-enhanced ultrasound (CEUS) images. Results The liver sonographic features of 18 HL were differentiated as three types including nodular, diffuse and mixed type. Nodular type showed well-deifned hypoecho lesions in 6 cases with penetrating vascular lfow signals in 2 cases and no vascular lfow signals in 6 cases by color Doppler imaging. In 3 cases by CEUS, all the hepatic focal nodulars showed variable arterial enhancement but wash-out in the portal venous and late phases. For diffuse type cases, hepatomegaly without nodule was showed in 11 cases. Vasular in liver showed normal in 8 cases and abnormal in 3 cases. For mixed type cases, hepatomegaly and multiple ill-deifned hypoechoic lesions with normal vascular in liver were showed in 1 case. Hepatosplenomegaly and abdominal lymphoadenopathies were identiifed in 11 cases. Conclusions The characteristics and the types of sonographic ifndings may be helpful in differentiating HL from other liver lesions.
