OBJECTIVE:To investigate clinical efficacy and safety of breviscapine combined with vinpocetine in the treatment of acute cerebral infraction. METHODS:A total of 80 patients with acute cerebral infraction were selected from our hospital during Jan. 2014-Dec. 2015,and then divided into observation group and control group according to random number table,with 40 cases in each group. Control group was given Vinpocetine injection 20 mL+0.9% Sodium chloride injection 250 mL,ivgtt,qd. Observa-tion group was additionally given Breviscapine injection 20 mL+5% Glucose injection 250 mL,ivgtt,qd,at intervals of 2-3 h on the basis of control group. Both groups were treated for 2 weeks. Clinical efficacies as well as serum copeptin,NT-proBNP,albu-min cobalt binding(ACB)value,European stroke scale(ESS)and functional independence measurement(FIM)score before and after treatment were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:Total response rate of observation group(90.0%)was significantly higher than that of control group(67.5%),with statistical significance(P<0.05). Before treat-ment,there was no statistical significance in serum peptide,NT-proBNP,ACB value,ESS or FIM score between 2 groups (P>0.05). After treatment,serum copeptin and NT-proBNP levels of 2 groups were decreased significantly,while ACB value,ESS and FIM score were increased significantly;the improvement of observation group was significantly better than that of control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Breviscapine combined with vinpocetine can improve neurological function of acute cerebral infraction patients and show good therapeutic efficacy with good safety.

OBJECTIVE To investigate the risk factors for nosocomial pneumonia(NP) caused by imipenem-resistant Acinetobacter baumannii(IRAB) and its antimicrobial susceptibility in vitro. METHODS The data of 34 cases of IRAB-NP were analyzed and 68 cases of NP caused by imipenem-susceptible A.baumannii(ISAB) were randomized as control.Antimicrobial susceptibility(MIC) was determined with the method of agar dilution. RESULTS The two independent factors associated with the development of IRAB-NP: previous fluoroquinolone(OR=5.738) and imipenem/meropenem(OR=7.129) use.The drug sensitivity test in vitro showed that these strains were multiresistant to commonly used antibiotics,and only ampicillin/sulbactam and cefoperazone/sulbactam whose resistance rate was less than 30%. CONCLUSIONS Previous imipenem/meropenem and fluoroquinolone use is independent risk factors for IRAB-NP.These strains are high drug resistant.

Objective To investigate the value of functional MRI in the diagnosis and differential diagnosis of breast diseases.Methods Sixty-five patients with 68 lesions were enrolled in this study. Conventional T_1 WI and T_2 WI scan,dynamic contrast enhanced MRI,diffusion weighted imaging and ~1H single voxel MR spectroscopy were performed consequently.All lesions were verified by pathology,including 4 cases of breast adenosis,22 fibroadenomas,2 chronic inflammations,3 cysts,33 infitrating ductal carcinomas,1 intraductal carcinoma and 3 cystosarcoma phyllodes tumors.Morphological features,maximum enhancement ratio,time-intensity curve,apparent diffusion coefficient and Choline peak were analyzed. Results The detection rates of T_1 WI and T_2 WI were 14.7%(n=10)and 51.5%(n=35).The sensitivity,specificity,accuracy of dynamic contrast.enhanced MRI for the malignant tumor were 94.6%, 71.4% and 76.5% respectively.Retrospective study showed that diffusion weighted imaging,with the b value from 800 s/mm~2 to 1000 s/mm~2,could be used to differentiate various types of breast lesions.~1H signal voxel spectroscopy had a sensitivity of 51.4%,specificity of 82.6%,and accuracy of 67.6% for the malignent.The sensitivity,specificity and accuracy could reach 97.3%,90.0% and 92.6% respectively by combining conventional scan,dynamic contrast enhanced MRI and MR spectroscopy.Conclusion Functional MRI,with high sensitivity,specificity and accuracy,can be used widely in the diagnosis of malignant breast lesions.

Biological characteristic of Salvia miltiorrhiza f. alba in field was studied. HPLC method was used to determine the lipophilic constituents (dihydrotanshinone, cryptotanshinone, tanshinone, tanshinone II (A) and miltione) and hydrophilic constituents (salvianolic acid, rosemarinic acid). The results showed that the fresh weight of S. miltiorrhiza f. alba which cropped for 2 years was decreased by 80.47%, while dry weight decreased by 79.42%. The normal diameter of the root was 0.3-0.5 cm, however, the diameter was 0.2-0.4 cm after 2 years, it was said that the decrease of the root diameter was the main reason for the decrease of the yield. The average contents of dihydrotanshinone, cryptotanshinone, tanshinone, tanshinone II (A), miltione, salvianolic acid and rosemarinic acid were decreased by 35.26%, 32.26%, 19.35%, 3.39%, 64.40%, 66.93% in plant which continuously cropped for 2 years, respectively. The yield and active constituents were mostly effected in the plant of S. miltiorrhiza f. alba, which continuously cropped for 2 years.

ObjectiveTo study the dose distribution of the intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) inverse plans with different energy X-ray, to provide a reference of energy options for radiation therapy. MethodsEight cases with different disease were chosen, the plan for each case were finished with 1Arc (360°) VMAT, 9 fields IMRT and 5 fields IMRT.For each plan project, the energy selections were 4 MV, 6 MV, 8 MV and 15 MV. In the evaluation,homogeneity index ( HI), conformity index ( CI ) and external volume index ( EVI ) of target, the average dose ( Dmean) and 2% volume in dose volume histogram ( D2 ) of serial organs at risk ( OARs), the average dose ( Dmean ) and a dose level volume ( Vx ) of parallel OARs were chosen and compared . Results Statistical analysis showed that: For the target, the result of HI were F=0. 13,0. 51,0. 09, P=0. 939,0.679,0.965,CI were F=0. 13,0.51,0.09,P=0.939,0.679,0.965, EVI were F=0. 15,0.31,0. 15,P =0. 930,0. 818,0. 931, respectively ; For the OARs of each patient, F < 0. 20, P > 0. 05. All results indicated there was little difference in option of energy for the same field p8roject. ConclusionsThe results indicate that the middle and low energy X-ray (6 MV or 8 MV) can satisfy the needs of IMRT and VMAT radiotherapy. Compared with middle and low energy, the high energy X-ray (15 MV ) showed little advantage in dose distribution.

Objective To investigate the effect of dexmedetomidine on brachial plexus block with ropivacaine and upper extremity ischemia-reperfusion (I/R) injury in patients undergoing upper extremity surgery. Methods Forty ASA Ⅰ or Ⅱ patients of both sexes, aged 18-55 yr, weighing 45-80 kg, scheduled forupper extremity surgery under brachial plexus block, were randomly divided into 2 groups ( n = 20 each): control group ( group C )and dexmedtomidine group (group D). In group C, brachial plexus block was performed using 0.5% ropivacaine 30 ml. In group D, brachial plexus block was performed with a mixture (30 ml) of 0.5% ropivacaine and 8 mg dexmedetomidine. The efficacy of motor and sensory block was evaluated and the onset time and duration of motor and sensory block were recorded. Venous blood samples were obtained from peripheral vein on the operated side before anesthesia induction (T0), and at 1, 5 and 30 min after tourniquet release (T1-3) to detect the plasma concentrations of MDA and ischemia-modified albumi (IMA). Arterial blood samples were also obtained at the same time points for blood gas analysis. The complications such as nausea and vomiting, respiratory depression, bradycardia and dizziness were recorded. Sufentanil 0.2 μg/kg was given as rescue medication. If the operation could not be completed, general anesthesia was used. Results There was no requirement for rescue analgesics and general anesthesia, and no complications occurred in all the patients. The duration of sensory and motor block was significantly longer, the plasma concentrations of MDA and IMA were significantly lower, and PaO2 and BE were significantly higher in group D than in group C ( P < 0.05). The plasma concentrations of MDA and IMA were significantly higher at T2 and T3 in both groups, the pH value was significantly lower at T1 in group C, PaO2 at T1 and BE at T1 and T2 were significantly lower in both groups than those at T0 ( P < 0.05). Conclusion Dexmedetomidine can not only enhance the efficacy of brachial plexus block with ropivacaine, but also reduce the upper extremity I/R injury caused by tourniquet in patients undergoing upper extremity surgery.
