Objective To study the influence of carbon dioxide pneumoperitoneum on BIS and oxygen metabolism in patients underwent laparoscopic hysterectomy in propofol and sevoflurane anesthesia. Methods 100 cases undergoing laparoscopic hysterectomy were selected in the second hospital of Shandong university and were divided into group A and group B, 50 cases in each group. Group A were received propofol and group B were received sevoflurane anesthesia . The oxygen metabolism index in the two groups were compared before and after pneumoperitoneum. Results The PETCO2 of two groups at the time points after pneumoperitoneum were significantly higher than those before pneumoperitoneum (P<0.05). There was no significant difference of the SpO2 in two groups at the different time points during pneumoperitoneum, The HR and MAP of the group A were significantly lower than that of group B (P<0.05). There were no significant difference of the PETCO2、SpO2 between two groups. Bis in 2 groups maintained a stationary state before and after pneumoperitoneum. There was no significant difference in the period between the two groups. The CjvO2、Lac of two groups were significantly higher than that before pneumoperitoneum (all P<0.05).The CjvO2、Lac of two groups were significantly lower than that before pneumoperitoneum (all P<0.05). The CjvO2 of group A at 40 minutes after pneumoperitoneum were higher than that of group B (P<0.05), and the level of CERO2、Da-jvO2 were lower than that of group B (P<0.05). But there were no difference of the BIS、CaO2 and Lac between two groups. Conclusion Carbon dioxide pneumoperitoneum can affect the BIS and oxygen metabolism in patients underwent laparoscopic hysterectomy. The effect in propofol anesthesia was more significant than that in sevoflurane anesthesia.

Objective To explore the methods of the hemorrhage prevention and the measures of hemostasis by CT guided after renal cancer cryoablation.Methods Retrospective analysis of 8 patients of renal cell carcinoma patienthave been done,all the patients were underwent cryoablation.The basic model included 10 min frozen,3 min thawed and 1 cycle were repeated.Before the cryoprobe puncture,a CT scan was taken to observe the blood supply of the tumor and the relationship between the border of the tumor and renal cortex,renal pelvis.Besides,the path of reducing the injury of normal renal cortex and renal pelvis was chosen,and the decreased number of probes was adopted by taking conformal cryoablation to reduce the damage to the renal capsule,in theensurance of the treatment efficacy.Intraoperative CT scan was performed discontinuously,to observe the covering status of the range of ice ball on the lesion and to monitor the perirenal bleeding.Postoperative ECG and blood pressure changes was observed 24 h after operation.Besides,CT scan or blood routine examination is necessary to monitor whether active bleeding happened.Results According enhanced CT image positioning puncture path,the path of probes were selected in the shortest path between the tumor margins and the renal cortical which avoid the renal pelvis.Probes were CT-guided conformal puncture into the lesion successfully for 8 patients,according to freezing basic mode to complete cryoablation.Timely intraoperative CT scan can clearly observe that a low-density ice ball wrapped lesion completely without involving the renal pelvis and normal tissue surrounding the kidney.There was no bleeding in the procedure of cryoablation.After the probe was pulled,CT scan showed:3 of the 8 patients didn't show any sign of henorrhage,in which 1 patient had heavily bleeding,about 150 ml due to the biopsy after cryoablation.The bleeding was stopped by interventional embolization.A little hemorrhage was found in two patients,about 10 ml outside renal capsule.Medium hemorrhage took place in two patients,30 nl in one patient which underwent several cycles of thawing and 60 ml in another.The patients of mild and medium hemorrhage was treated with intravenous injection of Reptilase and strict bed rest.There was a great hemorrhage in one patient,about 200 ml.The bleeding was stopped by interventional embolization.A small and moderate bleeding,it necessary to execute intravenous infusion 2 IU reptilase and strict bed rest.There was no significant active bleeding from the CT scan after 24 h operation and no change in the blood routine examination of blood hemoglobin and red blood cell count.Conclusions Before the puncture,it is necessary to perform an enhanced CT scan to understand the position,which can determine the path of the puncture.It can reduce the damage of renal cortex,renal capsule and surrounding tissue and prevent and reduce the risk of bleeding.For larger amounts of intraoperative and postoperative bleeding subjects,the embolization should be given immediately,as for the small or moderate amount of bleeding,the conservative treatment may be given firstly.

Objective To evaluate the clinical efficacy and safety of methotrexate(MTX) plus low dose glucocorticoid in the treatment of rheumatoid arthritis (RA) from thetarget control point of view.Methods Patients diagnosed as RA according to American College of Rheumatology(ACR)/European League against Rheumatism (EULAR) 2010 classification criteria were enrolled.All of the patients were prescribed with 15 mg/week MTX,5 mg/week folic acid and prednisone (not exceeding 10 mg/day) orally.At week 0,4,12,disease activity and clinical efficacy were recorded.Co-primary assessment criterion was disease activityscore (DAS28)-based on C-reactive protein (CRP).Secondary assessment criteria included EULAR response criteria,ACR response criteria,simplified disease activity index(SDAI),clinical disease activity index(CDAI).The tolerability and toxicity of MTX was recorded at week 4,12.All patients were evaluated for the occurrence of adverse drug reactions associated with prednisone at week 12.Results A total of 76 patients were enrolled in the study.At week 4 and 12,68 and 65 patients completed regular follow-up respectively.At week 12,there were 30(46.2％),9(13.8％),26(40.0％) patients who met DAS28-CRP remission,low disease activity,middle and high disease activity criterion respectively.Three of nine patients who grouped in low disease activity after therapy were early or intermediate patients and didn't reach the target.Thus 36 (55.4％) patients met the standard of target control.The percentage of patients who met the criteria of EULAR good response,the ACR criteria for 20％ improvement (ACR20),the ACR criteria for 50％ improvement (ACR50),the ACR criteria for 70％ improvement (ACR70) were 29.2％,75.4％,69.2％,64.6％,respectively.The proportion of patients meeting the standard of treat to target using SDAI and CDAI were 76.9％,58.5％ respectively.The rate of liver injury,abdominal pain,abdominal distention and acid reflux,nausea were 11.8％,4.4％,4.4％,2.9％ respectively at week 4.At week 12,4.6％ of patients reported abdominal distention.There was only one patient (1.5％) each who complained of abdominal pain,nausea,loss of hair,varicella zoster virus infection and pulmonary infection at week 12.No serious adverse event was observed during the study.Conclusions Based on the view of target control,drug efficacy and safety,MTX plus low dose prednisone is still a useful therapeutic regimen for RA at present.

Objective To explore the clinical and radiographic outcomes of minimally invasive transforarninal lumbar interbody fusion (MIS-TLIF) with unilateral pedicle screw fixation in treatment of one-level lumbar degenerative disease.Methods A total of 65 patients suffered from one-level lumbar degenerative disease between October 2009 and December 2011.They were divided into 2 groups according to different fixation ways.31 patients were given MIS-TLIF with unilateral pedicle screw fixation.The other 34 patients were given MIS-TLIF with bilateral pedicle screw fixation.Microscopic tubular retractor system (METRxMD) and Sextant system were used in all the procedures of treatment.The whole lumbar lordosis (WL),the segmnental lordosis (SL),fusion level disc space angle,lumbar scoliosis angle,and segmental scoliosis angle were measured pre and post operation according to standarded X-rays.The disc height index (DI) and the lumber curvature index (LI) were also evaluated.The Oswestry disability index (ODI) score and visual analog scale (VAS) pain score data were obtained from all the patients pre-operation and during each following-up procedure.Results All the patients were well followed up 18 months to 36 months(average 26.6 months).All the 65 patients were proved to achieve bone fusion in 12 months post-operation.The ODI and VAS scores post-operation improved significantly in each group,but showed no significant difference between the 2 groups.Likewise,there were no significant differences between the 2 groups in datas of WL,SL,fusion level disc space angle,lumbar scoliosis angle,segmental scoliosis angle,DI,and LI.But there was a positive linear correlation between the LI and WL in the 2 groups.Conclusion MIS-TLIF with unilateral pedicle screw fixation is as good as MIS-TLIF with bilateral pedicle screw fixation in patients of one-level lumbar degenerative disease.

Objective To explore how to elevate the efficiency of fetal heart screening.Methods Volume data of 83 normal fetuses ranging between 20 to 24 gestational weeks were acquired by spatiotemporal image correlation (STIC) with the apical four-chamber view(4CV).Tomographic ultrasound imaging (TUI) was then used to present the different views of fetal hearts,and were compared with those aquired by 2-dimensional (2D) ultrasound.Results All the 83 volume datasets were obtained by STIC.(1) Qualification ratio of short axis view of the aorta (SAV) by TUI was higher than that of 2D (94.0％ vs 84.3％,x2 =5.57,P=0.042).While,in the other 8 planes,the qualification ration by STIC were higher than that of 2D,however no significant difference was found (P＞0.05).(2) In 4CV,5-chamber view (5CV),left ventricular outflow tract view (LVOT),right ventricular outflow tract view (RVOT) and SAV,STIC showed excellent consistency with 2D (Kappa =0.79,0.90,0.92,0.93 and 0.77,respectively).And in long axis view of the aortic arch (LAV-AoA),long axis view of the duct (LAV-DA),superior and inferior vena cava (SVC+IVC) and short axis view of the ventricle (SVV),STIC showed good agreement with 2D (Kappa=0.72,0.67,0.74 and 0.70,respectively).(3) Image collecting time of T2D,TSTIC,TTUI and TSTIC+TUI were (5.80±1.58) min,(0.85±0.18) min,(2.57±1.32) min and (3.29±1.13) min,respectively.There were significant difference between TSTIC and T2D(t=3.500,P=0.000) and between TSTIC+TUI and TTUI (t=2.877,P=0.001).Conclusion The technique of STIC-TUI used in this study can display the standard planes of fetal heart conveniently,clearly and in shorter time.It is helpful for improving the quality and efficiency of fetal heart screening.

Objective To investigate clinical significance of counting follicles classification by three-dimensional imaging with sonography based automated volume calculation(SonoAVC)in the diagnosis of polycystic ovary syndrome(PCOS).Methods Eighty cases with PCOS were counted classified follicles and determined ovarian volume by three-dimensional(3D)imaging with SonoAVC method matched with 60 infertile women with fallopian tube or male factors as control.Main clinical.biological and other ultrasonographic markers were assessed during the early follicular phase,and the relationship between the follicle number range per ovary or the volume per ovary and the major hormonal features of PCOS was studied.Results Three-dimensional ultrasound imaging with SonoAVC methed provides a new path for objective quantitative assessment of follicle count.ovarian volume,total follicle numbers.The volume of (11 ±8)ml,total numbers of 27 ±14 follicle and number of22 ±19 follicle with diameter of≥2-＜6 mm in PCOS patients were significantly higher than(6 ±4)ml in ovarian volume.6 ±4 in total follicles and 2 ±3 in follicle with diameter of≥2-＜6 mm in controls(P＜0.05).while follicles were similar for the≥6-≤9mm range(P＞0.05).Total follicle numbers and follicles≥2-＜6 mm had significantly positive relationships with ovarian volume ( r= 0. 600, 0. 618, P＜0. 01 ) and level of testosterones ( r= 0. 364,0. 291, P＜0.05), follicles ≥2-＜6 mm also had significantly positive relationships with total follicle number (r=0. 916,P＜0. 01 ). The follicles within the ≥6 - ≤9 mm range was significantly and negatively related to ovarian volume and total follicle numbers ( r = - 0. 618, - 0. 263, all P = 0. 001 ), but no significantly related to the major hormonal features of PCOS. The ovarian volume was significantly positively related with luteinizing hormone ( LH)/follicle stimulating hormone (FSH) ratio ( r= 0. 282, P = 0. 010)but negatively related to FSH level (r = - 0. 226, P = 0. 042). Conclusions Ovarian volume, total follicle numbers and follicles ≥2 - ＜6 mm in PCOS patients were significantly higher than those in controls. The larger ovarian volume might produce more total follicle and follicles ≥ 2 - ＜6 mm. The higher level of testosterone might produce more total follicle probably, which mainly result in more follicles ≥2 -＜6 mm.These morphologically ultrasonographic characteristics could reflect pathophysiological changes in PCOS. Obviously, it has important clinical significance to count follicles in patients with PCOS by the threedimensional ultrasound imaging with SonoAVC method.
