Objective To study pharmacodynamic changes of combined anesthesia with remifentanil at different target plasma concentrations and isoflurane at different minimal alveolar concentrations(MAC) in laparoscopic operations. Methods Forty-five patients with ASA status Ⅰ~Ⅱ,receiving selective laparoscopic cholecystectomy or laparoscopic oophorocystectomy,were included.The patients were randomly divided into three groups with 15 patients in each group.In the Group A,anesthesia was maintained with isoflurane inhalation at the MAC of 1.3;in the Group B,anesthesia was maintained with both isoflurane inhalation at the MAC of 0.6 and remifentanil target-controlled infusion at 4 ng/L;and in the Group C,anesthesia was maintained with both isoflurane inhalation at the MAC of 0.4 and remifentanil target-controlled infusion at 6 ng/L.Pharmacodynamic parameters and recovery characteristics,including bispectral index(BIS),heart rate variability(HRV),mean arterial pressure(MAP),heart rate(HR),time to additional administration of muscle relaxants,time to the recovery of spontaneous breathing,time to eye opening,time to endotracheal extubation,time to the recovery of orientation,and follow-up survey of "awareness during operation",were compared among the 3 groups.Results ①The BIS value was lower in the Group A than in the Group B and C at the time of pneumoperitoneum for 2 min and removal of the gallbladder or the ovarian cyst.The measures of HRV were higher in the Group A than in the Group B and C at the time of pneumoperitoneum for 2 min and removal of the gallbladder or the ovarian cyst.The measures of MAP and HR in the Group A were higher than those in the Group C at the time of pneumoperitoneum for 2 min,and were lower than those in the Group C at the time of the endotracheal extubation and the recovery of consciousness.②Either isoflurane inhalation at the MAC of 0.6 combined with remifentanil target-controlled infusion at 4 ng/L or isoflurane inhalation at the MAC of 0.4 combined with remifentanil target-controlled infusion at 6 ng/L provided satisfactory anesthetic maintenance.③Significantly shorter time to endotracheal extubation,to eye opening,and to the recovery of orientation were recorded in the Group B and C than in the Group A.Conclusions Anesthesia with target-controlled infusion of remifentanil combined with inhalation of isoflurane can be used for laparoscopic surgery.Pharmarcodynamic parameters and recovery characteristics show that combined use of remifentanil infusion at 4 ng/L and isoflurane inhalation at the MAC of 0.6 provides optimal anesthetic maintenance.

BackgroundHypoxia and hyperglycemia are the common causes of retinal neovascularization.In these states,H+ accumulates because of the elevated glycolysis and failure of retinal circulation,thus the retinas readily acidified. ObjectiveThe present study was to explore whether retinal acidosis independently regulates the production of vascular endothelial growth factor (VEGF) and pigment epithelium-derived factor (PEDF) and whether the regulation is related to oxidative stress.Methods The retinas from 2-week-old male SD rats were cultured with explant method in DMEM modulated by NaHCO3,and culture retinas were randomly divided into pH 7.2,6.8 and 6.5 groups for 24 hours.In addition,after 24 hours of culture as above described,retinas were washed using PBS two times and then followed by again culture in DMEM with pH 7.2 for another 24 hours.Also,antioxidant was added in different pH values of DMEM for culture as above described.The retinal samples were prepared for histopathological examination.The expressions of VEGF and PEDF proteins and their mRNA in retina tissue were detected by Western blot and fluorescence quantitative polymerase chain reaction (PCR) respectively.Results The retina showed the clear structure and morphology in pH 7.2 group and pH 6.8 group,but retinal vacuoles change was seen in pH 6.5 group after culture for 24 hours.No significant difference was seen in the expressing level of VEGF mRNA in retina between normal group and pH 7.2 group( 112％ ±11％ vs 100％ ±7％ ) (P=0.55),but those in pH 6.8 group and pH 6.5 group were significant increased in comparison with pH 7.2 group( 196％ ±43％ vs 100％ ±7％ ;251％ ±29％vs 100％ ±7％ )( P＜0.05 ).The expressing level of PEDF mRNA in retina in normal group was similar to that of pH7.2 group(86％ ±19％ vs 100％ ±33％) (P=0.64),but that in pH 6.5 group was significantly higher than pH 7.2 group( 230％ ±66％ vs 100％ ±33％ ) ( P＜0.05 ).The resemble results were found in the expressions of VEGF and PEDF protein.After pH reversion,the expressing levels of VEGF mRNA were 100％ ±13％,111％ ±9％,113％ ±9％ in pH 7.2 group,pH 6.8 group and pH 6.5 group respectively without significant difference among them (F=2.51,P=0.16).The expressing levels of PEDF mRNA were 100％ ±13％,110％ ±9％,108％ ±11％in different groups ( F =0.98,P =0.43 ).Under the presence of antioxidant,the expressing level of VEGF mRNA in pH 6.5 group increased in comparison with pH 7.2 group and pH 6.8 group ( P ＜ 0.05 ).The expressing levels of PEDF mRNA were significant different among pH 7.2 group( 100±31 )％,pH 6.8 group( 282±45 )％ and pH 6.5 group(480±117)％ (F=20.73,P=0.00). Conclusions VEGF can be induced by retinal acidification alone,which may be regulated by oxidative stress.Under the retinal acidification,antioxidants promote the expression of PEDF,suggesting that oxidative stress inhibits the production of PEDF.

Objective To investigate the characteristics of electroencephalograms ( EEGs ) of patients with childhood absence epilepsy ( CAE ) .Methods EEG of 46 patients with CAE were analyzed .Results Of 46 patients,there were 44 cases (95.6%) with guided bilateral symmetry 3Hz spike-and-wave.16 cases were character-ized by multiple spike-and-wave on the 3Hz spike and slow wave;and the centrotemporal spikes was found in 1 case. Additionally,the 3Hzδactivity in occipital region has been traced in 34 cases of these 46 patients.Conclusion In general,the EEGs of CAE patients have typical characteristics ,and few of them showed atypical manifestation ,which must be verified by clinical attention .

Objective To evaluate the key points of anesthetic management for retroperitoneoscopic nephrectomy combined with inferior vena cava ( IVC ) tumor thrombectomy. Methods Perioperative clinical data of 3 patients undergoing retroperitoneoscopic nephrectomy combined with IVC tumor thrombectomy from December 2010 to June 2014 were retrospectively analyzed.There were 2 cases of level Ⅰthrombus and 1 case of level Ⅱthrombus.All the patients were given general anesthesia with intubation.Brief inferior vena cava occlusion was performed in the patient with level Ⅱ thrombus. Results The operation was completed smoothly in all the cases without conversions to open surgery. The operating time was 244, 333, and 289 min, respectively. The total IVC control time for level Ⅱ thrombus was 10 min.No intraoperative pulmonary embolism and other severe anesthetic complications occurred. One patient with level ⅠIVC thrombus was extubated and sent back to surgical ward after surgery, and the remaining 2 patients underwent intensive care monitoring overnight and were extubated and discharged to surgical ward on the next day. Conclusions Retroperitoneoscopic nephrectomy and IVC thrombectomy is a brand-new, difficult but feasible procedure. Anesthesiologist should have a full recognition of surgical procedures and make perfect anesthetic plan to ensure close collaboration. Furthermore, circulatory swing during IVC clamping and perioperative severe complications such as pulmonary embolization and massive hemorrhage cannot be neglected.

Objective To investigate the diagnosis and treatment procedures of primary colonic malignant lymphoma(PCML). Methods Data of clinical and pathological findings, surgical treatment and prognosis of 12 cases with PCML verified by pathology were retrospectively analyzed, workups of barium clysma,colon-scopic examination and multislice spiral computed tomography(MSCT) were compared to evaluate their role in diagnosis. Results The classic presentation of PCML included abdominal pain, abdominal bulge, bowel obstruction, gastrointestinal bleeding, and serum levels of tumor markers were within the normal ran-ges. Six cases underwent procedure of barium clysma, and anomaly appeared in 2 cases, however, there were no indications of lymphoma, 6 cases underwent colon-scopic examination, anomaly in 3 cases, of which 1 revealed possibility of lymphoma, 10 cases underwent MSCT; 9 cases demonstrated tumor origin by CT scan of which diagnosis was established in 5 cases. All the patients underwent surgery. No incidence of peri-opreative death happened. Non-Hodgkin' s lymphoma was confirmed in all of cases. For all of the cases a T-cell origin was in 1 case and a B-cell origin in other cases. Ten cases were administrated postoperative chem-otherapy. 11 cases were followed up, and the overall 1-year and 3-year survival rates were 81.9% (9/11) and 54.5% (6/11), respectively. Conclusions Typical presentation is still lacking for PCML, workups of barium clysma and colon-seopic examination are little sensitive and specific to make the diagnosis. However, MSCT is useful in diagnosing PCML with its characteristic information as well as clinical findings. Surgical management and postoperative adjuvant-chemotherapy would be likely the optimal therapeutic maneuver of this disease in early period.

Objective To explore the hemodynamics changes of patent foramen ovale (PFO) ofnewborn and early infant.Methods Two groups of cases were analyzed in the study.One group was 60 cases of left-to-right(L-R)shunt in fossa ovalis(FO),the other group was 31 cases of PFO that were foundduring corrective heart surgery but no shunts in FO detected by echocardiography.ACUSON 128 was used.The main indexes were mobility of FO valve,phase,direction,velocity of shunt in FO,jet width.Results ①Valve of FO moved from left to right and right to left with the change of cardiac-period;②44 cages appeared that the jet with<5 mm,Doppler spectrum was two-peaks, positive continuity,peak flow velocity <0.5 m/s;③1 6 cases appeared that the jet width>6 mm,postive wide spectrum,continued from latesystole to diastole,peak flow velocity>0.6 cm/s;④Inside diameter in surgery group was 2～6 mm,meanvalue was 3.4 mm.Conelusions FO valves appears two-directional shunt,the PFO of newborn and early infant mostly appears left-to-right shunt.Atrial septal defect could be diagnosed when the jet width>6 mmand peak flow velocity>0.6 m/s.
