OBJECTIVETo explore an optimal anesthesia method with less impact on hemodynamics and electrocardiogram (ECG) of old patients with coronary artery disease (CHD) during abdominal operation.

METHODSThe 133 CHD patients waiting for abdominal operation were randomly divided into continuous epidural anesthesia (EA) group, general anesthesia group (GA) and combined spinal-epidural anesthesia (CSEA) group. Continuous monitoring was carried out during operation and mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SaO2), abnormal ECG were measured respectively at different time for comparison and the differences of the above hemodynamic parameters and abnormal ECG features were compared among the 3 groups.

RESULTSAt the 15 min and 30 min point after anesthesia, SaO2 in GA group was significantly increased compared to that in the EA group (P < 0.05). At 15 min, 30 min and 60 min point after anesthesia, MAP in CSEA group was significantly increased compared to that in the EA group (P < 0.05). At 30 min point after anesthesia, HR in CSEA group was increased significantly compared to the EA group (P < 0.05). At 15 min and 30 min point after anesthesia, SaO2 in the CSEA group was increased significantly compare to the EA group (P < 0.05). Compared with preanesthesia (T0) in EA group, MAP, HR and SaO2 decreased significantly at 15, 30 and 60 min after anesthesia (P < 0.05). The fluctuation of the three parameters in GA and CSEA groups were relatively small (P > 0.05). As well as the comparison of abnormal ECG among the 3 groups was concerned, the incidence of ST-T changes in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia and at the time of surgery termination (P < 0.05, P < 0.01). The incidence of arrhythmia in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia (P < 0.05, P < 0.01). Compared with T0 in the same group, the incidences of ST-T changes and arrhythmia in GA or CSEA group at the time of 15, 30 and 60 min after anesthesia and at the time of surgery termination were significantly lower than that before anesthesia (P < 0.05, P < 0.01).

CONCLUSIONGA and CSEA have less impact on hemodynamics and have smaller incidence of abnormal ECG of old CHD patients with abdominal operation.

This study is to investigate the effect of Vam3, a dimeric derivative of resveratrol, on SNP-induced apoptosis and its potential mechanism in rat articular chondrocytes. Isolated rat articular chondrocytes were treated with sodium nitroprusside (SNP), a NO donor, to induce apoptosis. Apoptosis percentage was evaluated by Annexin V-PI and nucleus fracture was examined by DAPI staining. Level of intracellular reactive oxygen species (ROS) was detected using 2, 7'-dichlorofluorescin diacetate (DCFH-DA) as a fluorescence probe by fluorescence microplate reader. The change in mitochondrial membrane potential was detected by TMRE staining. Expressions of SIRT1, acetylated p53 (ac-p53), cleaved caspase 9 and cleaved caspase 3 were determined by Western blotting. It showed that Vam3 up to 10 micromol x L(-1) could significantly reduce SNP-induced rat articular chondrocytes apoptosis (P < 0.01) and nucleus fracture, inhibit the increase of intracellular ROS level (P < 0.01) and reverse the decrease in mitochondrial membrane potential (P < 0.01). Simultaneously, Vam3 could upregulate the expression of SIRT1, deacetylate p53, and inhibit the cleavage of caspase 9 and caspase 3 (P < 0.01) of rat articular chondrocytes exposed to SNP. This study indicates Vam3 could protect rat articular chondrocytes against SNP-induced apoptosis, perhaps through the upregulation of SIRT1 and deacetylation of p53.

Objective To study the structure of class 1 integrons in 90 strains of Pseudomonas aeruginosa isolated during two periods of 1992-1996 and 2003-2005,and to get information about the structure changing of class 1 integrons by comparing their structures in two different periods.Methods Routine PCR and long PCR were performed to amplify the class 1 integrons and the gene cassettes they carried, followed with sequencing and blast via GenBank.Results Thirteen out of 41 strians ioslated during the period of 1992-1996 were positive on class 1 intergrons.Long PCR showed that the class 1 integron was 1868 bp in length and contained 2 resistance genes averagely.Six types of resistance genes of qacEA1 (n=6), sull (n=14),aadA1 (n=2),aadB (n=1),PSE-1 (n=2) and tetA (n=1) were found in these integrons, which consisted of 5 patterns of resistance cassette arrangements.Nineteen strains were proved to carry class 1 integrons in 49 isolates from 2003-2005.The mean DNA sequence length of them was 3383 bp with 3.6 resistant genes in averagely,10 types of resistance genes,qacEA1 (n=18),sull (n=25),aadA1 (n=6), aadB (n=7),aacA4 (n=2),PSE-1 (n=3),VEB-1 (n=4),OXA10 (n=1),cm1 A (n=1) and tetA (n =2),were identified in these integrons,which were composed of 9 patterns of resistance cassette arrangements.Conclusion In terms of produce length and resistance cassettes carried in the integrons, greater complexity is found in the structure of class 1 integrons in strains isolated during 2003-2005 than those during 1992-1996.

Objective To evaluate the feasibility and efficacy of percutaneous nephrolithotomy (PCNL)in treating renal calculi.Methods The data of 118 patients with renal calculi who had underg- one PCNL from July 2002 to August 2004 were retrospectively analyzed.There were 86 men and 32 women. The mean age was 39 years(range,7-68 years).Of the 118 cases,11 had pelvic calculi,16 had calyx cal- culi,35 had pelvocalyceal calculi,54 had staghorn calculi,and 2 had bilateral renal calculi.The mean stone size was 2.5 cm?1.5cm(ranged from 2.0 cm?1.0 cm to 4.5cm?4.0cm).Results Of the 118 ca- ses,112 underwent one-stage PCNL,and 6,two-stage PCNL.The procedure was performed by single tract in 114 cases,and by two tracts in 4 cases.Lithotomy was done by one session in 60 cases,by 2 sessions in 42 cases,and by 3 sessions in 16 cases.The total stone clearance rate was 81.4%.The mean operative time was 120 min,and mean hospital stay was 15 d.No blood transfusion was needed during operation,and only one patient experienced bleeding(about 500 ml)after 4 d postoperatively,and was cured by conservative treat- ment such as blood transfusion and anti-inflammation.No major complications were observed in other pa- tients.Conclusions PCNL has advantages of minimal trauma,less blood loss,fewer complications,and is safe and effective in treating renal calculi,especially for patients who will have the second procedure.

OBJECTIVETo explore the clinical effects and significances of a cervical anterior Hybrid technique with posterior longitudinal ligament retained in treating cervical spondylosis.

METHODSThe clinical data of 138 patients with cervical spondylosis underwent cervical anterior Hybrid surgery were retrospectively analyzed from March 2009 to March 2013. There were 52 males and 86 females,the age ranged from 36 to 58 years old with an average of 45.3 years. Course of disease was from 3 to 16 months. Cervical spondylosis classification included 22 cases with nerve root type, 68 cases with myelopathic type, 48 cases with mixed type. All patients were treated with the primary Hybrid surgery and their cervical posterior longitudinal ligaments were retained in anterior decompression. JOA score and image examination were used to evaluate clinical effect, and image examination included range of motion of the replacement segment, range of motion of the whole cervical spine, the sagittal diameter of the spinal cord before and after operation.

RESULTSAll operations were successful and operation time was 60 to 125 min (averaged 90.6 min), perioperative bleeding was 10 to 60 ml (averaged 30.1 ml). All patients were followed up from 12 to 48 months with an average of 22.2 months. All pathological segments obtained fully decompression, reserved posterior longitudinal ligament had no obvious hypertrophy, proliferation and calcification. The prosthesis had good location and the incision healed well without complications. Upper limbs root symptoms were completely relieved in the patients with cervical spondylotic radiculopathy, muscle strengths and sensations got different recovery in the patients with cervical spondylotic myelopathy. JOA score was increased from preoperative 8.62±1.22 to final follow-up 14.26±1.47 (P<0.05). Artificial intervertebral discs were stabilized in the patients, the replacement segment and range of motion of whole cervical spine were respectively (14.2± 5.6)° and (33.8±10.3)°, there was no significant differences between preoperative and postoperative (P>0.05). Spinal cord sagittal diameter was increased from preoperative (5.2±1.3) mm to postoperative (8.8±0.5) mm (P<0.05).

CONCLUSIONAnterior cervical Hybrid surgery with posterior longitudinal ligament retained can achieve fully decompression and good clinical efficacy, we recommend retaining the normal posterior longitudinal ligament in surgery as complete as possible.

Objective To evaluate the diagnosis values of whole blood IFN-γ release assay on pulmonary tuberculosis ( TB)and extra-pulmonary tuberculosis. Methods One hundred and eighty five patients with tuberculosis( including 119 pulmonary TB and 66 extra-pulmonary TB),139 patients with other respiratory diseases and 100 healthy people were enrolled. Mycobacterium tuberculosis infection testing was conducted with methods of IFN -γ release assay,sputum bacterial culture and sputum smear,respectively. Results of pathogen culture and/or clinical diagnosis were used as the golden standard to evaluate the sensitivity and specificity of these three methods. Results Compared with the results of clinical diagnosis,the sensitivity and specificity of IFN-γ release assays was 93. 51% and 84. 52%,respectively. There was no significant difference in sensitivity between pulmonary diagnosis( 90. 76%) and extra - pulmonary diagnosis (98. 49%)(P>0. 05). The sensitivity of sputum smear was 11. 76% in patients with pulmonary and 3. 03% in patients with extra - pulmonary. And the sensitivity of sputum bacterial culture in these two patient groups was 24. 37% and 3. 03%,respectively. Sensitivity of the IFN-γ release assay was higher than that of sputum culture and sputum smear (P<0. 05). The results of pathogen culture showed that 33 of 424 samples were positive,in which 2 were mycobacterium abscessus positive and 31 were mycobacterium tuberculosis positive. Compared with the results of pathogen culture,the sensitivity of IFN-γrelease assay was 90. 32%(95%CI:75. 10% -96. 65%). Conclusion IFN-γrelease assay is a fast,sensitive and convenient method to detect pulmonary and extra pulmonary tuberculosis. It is worthy to be applied to clinical practice.

OBJECTIVETo bring forward a method to improve the prominence of the forehead contour.

METHODS16 patients(age 29-53 years, female 11, male 5) were treated through a bicoronal incision. Following the incision, the forehead soft tissues are reflected down to the level of the superior orbital rims with the protection to the supraorbital neurovascular bundles. To adjust the forehead contour, both superior orbital rims and frontal bossing was reduced by burring down the excess bone or removing the anterior wall of the forehead.

RESULTSThe operative effect were satisfactory during 3-12 months of follow-up. No recurrence or osteogenesis were found in the cases. Nasofrontal angle and forehead angle were normal. The prominence of the supraorbital ridges disappeared and forehead became nature.

CONCLUSIONCranioplasty via an osteomy or burring of the outer line of forehead bone are safe, compact and effective way to improve the prominence of the superior orbital rims or frontal bossing.
