Objective To evaluate the effect of managed health education on psychological and nutritional status of patients with HBV-related cirrhosis and ascites.Methods One hundred and twenty one patents with decompensated HBV-related cirrhosis were enrolled for health education and randomly divided into two groups:61 patients received managed health education (trial group) and 60 received conventional health education (control group).In control group patients were informed with their condition and diet note by medical orders.In control group the hepatologists evaluated the baseline condition,nutritional status and quality of life,set up personal files of patients and followed up with communication and counselling periodically from June 2010 to August 2012.The psychological conditions were assessed with self-rating anxiety scale (SAS) and self-rating depression scale (SDS) ; nutritional status was assessed with triceps skinfold thickness (TSF) and mid-arm muscle circumference (MAMC) and the quality of life was assessed with MOS 36-item shoort from healthy survey (SF-36).Results Before health education,there was no statistical difference in the scores of SAS,SDS,TSF,SF-36 and blood Hb,albumin (Alb) levels between two groups.After health education,scores of SAS and SDS were decreased in both groups (P ＜ 0.0l),however,which in trial group were lower than those in control group (39.9 ±8.8 vs.49.0 ±9.4 and 40.6 ± 8.8 vs.51.9 ± 10.1 respectively,both P ＜0.01).The TSF scores and blood Hb and Alb levels in trial group were higher than those in control group (P ＜ 0.05).The accunulated scores of 8 dimensions in SF-36 forms in trial group were significantly higher than those in control group (P ＜ 0.01).Conclusion The managed health education model can better release psychological pressures,decrease mental disorders,elevate nutrition status,promote health and improve quality of life than conventional health education for patients with HBV-related cirrhosis and ascites.

Objective To evaluate the effect of recombinant activated factor Ⅶ (rⅦa) in treatment of hemorrhagic shock after severe multiple injuries with coagulopathy.Methods Sixteen cases of coagulopathy after severe multiple injuries administered with rⅦa between July 2011 and June 2012 were reviewed.The requirements of blood product and coagulogram variation were comparatively studied before and after rⅦa therapy.Results After rⅦa therapy,bleeding was brought to a halt in 24 hours for nine cases and in 72 hours for seven cases.In the end,13 out of the 16 cases survived in the absence of myocardial infarct,cerebrovascular accident or deep vein thrombosis.Requirements of red blood cells,fresh frozen plasma,cryoprecipitate and platelet (PLT) were decreased at 48 hours after the final therapy as compared with those at 48 hours prior to the primary therapy,but statistical significance only existed in the reduction of fresh frozen plasma and cryoprecipitate (P ＜ 0.05).The coagulogram indices including prothrombin time (PT) and activated partial thromboplastin time (APTT) at 4 hours after the final therapy presented statistical differences from those prior to the primary therapy (P ＜ 0.05).Conclusion rⅦa is an important,effective and safe auxiliary means for surgical hemostasis of coagulopathy after severe multiple injuries.

Objective To explore the cerebrovascular reactivity of the patients with cerebral infarction by transcranial color Doppler ultrasound (TCCD) and breath holding test.Methods TCCD was used to record the color Doppler imaging and Doppler spectrum and to measure peak velocity,mean velocity of double side middle cerebral artery(MCA) in thirty two normal persons and thirty seven patients with cerebral infarction confirmed by CT or MRI.Breath holding test was performed to record the Doppler spectrum and breath holding time and to calculate breath holding index(BHI).Results ①The peak velocity of MCA of the damaged side was abnormally increased by 35.1% and decreased by 40.5% .②The BHI of the damaged side was significantly lower than that of undamaged side and that of control group (P

Objective To assess the value of contrast-enhanced ultrasonography(CEUS)in evaluating the therapeutic efficacy of uterine leiomyoma treated by radiofrequency ablation(RFA)and to discuss the value of its application.Methods Forty-four patients which were diagnosed as uterine leiomyomas by ultrasonic guidance needle puncture biopsy preoperation were examined by CEUS before and one week after RFA treatment respectively,and the patho-results were got again after the surgery.Routine ultrasonography was performed in 1,3,6,12 months after the treatment to compare the volume change of uterine leiomyomas with the change of the clinical symptoms.Results After the treatment,CEUS showed that the contrast agent didn't appear in thirty-five patients'uterine leiomyomas and the nonperfusion regions matched the size of the uterine leiomyomas completely.The contrast agent enhanced on the edge of the uterine leiomyomas in nine,the patho-results confirmed that the nonperfusion regions of the contrast agent were necrosis tissues and the marginal local enhancement regions were incomplete necrosis.Three month after RFA treatment,the uterine leiomyomas began to shrink,which showed obviously in 6 months after the treatment.There were significant differences in the parameters before and after the treatment(P＜0.05).Clinical symptoms improved obviously in thirty-five patients(90%)after the treatment.Conclusions RFA is an effective minimally invasive surgery of the uterine leiomyoma.CEUS can identify the treatment range and the remaining tissues.It has significant value in guiding the supplementary treatment.

Objective To investigate the basis of ultrasound microbubble technology enhanced thermal ablation effect.Methods All 48 rabbits bearing hepatic tumors were averagely randomly divided into four groups:only laser group,sham,destruction + laser group,and blank group.The filling defect area changes of before and after treatment were observed and the differences between groups were compared.Results Pathology confirmed ablation of tumor tissue could produce coagulation necrosis for experiment group.The conventional ultrasound showed there was no significant variation in the maximum diameter and area in the pre and post treatment of experiment group and control group(P ＞0.05).There was no change for the control group.Ultrasound imaging showed an area of filling defect were:laser treatment alone group (0.83 ± 0.06) cm2,microbubbles false break combined with laser therapy group (0.65 ± 0.05) cm2,microbubbles break combined with laser therapy group (2.40 ± 0.16)cm2,blank control group (0.01 ± 0.01) cm2.The filling defect area of the treatment group,which was combined with ultrasound microbubble break technology and laser ablation was increased,there was significant variation in the each group (P ＜0.05).Conclusions Microbubble burst combined laser ablation could expand the single needle laser ablation area of rabbit VX2 liver tumor and increase the therapeutic effect.

A questionnaire and telephone survey was conducted on 246 patients with chronic liver diseases in the Outpatient Clinic from August 2010 to May 2011.The distribution of diseases and the causes of losing follow-up were analyzed. Most subjects in this survey (182/246,74.0％ ) were patients with chronic viral hepatitis( HBV or HCV)and cirrhosis; and their follow-up status was better than others (X2 =12.382,P ＜ 0.05). There were no differences in gender( X2 =10.137,P ＞ 0.05),but significant differences in age ( X2 =31.783,P ＜ 0.05 ) and educational levels ( X2 =32.803,P ＜ 0.05 ) between patients with chronic viral hepatitis and cirrhosis and patients with other liver diseases.The main causes of losing follow-up were neglect of disease by patients (38.3％) and lack of good communication between doctors and patients ( 18.3％ ).It is important to reinforce the understanding and awareness of chronic liver diseases for patients.

ObjectiveTo evaluate the value of the measurement with a scale in arthroscopic anatomic anterior cruciate ligament (ACL) reconstruction.Methods Thirty-six patients with unilateral ACL-deficient knees were divided into single bundle group and double bundle group based on the length of the major axis of the native ACL footprint measured with a scale.Consistent with the International Knee Documentation Committee (IKDC) scoring systems,Lysholm knee scoring scale and Tegner activity rating were used to evaluate the clinical results,and data from 23 to 26 months follow-up were gathered and analyzed statistically.ResultsIn terms of IKDC evaluation,19 patients( 90.4％ ) in the double band group and 13 patients( 86.7％ )in the single band group were graded as normal or nearly normal ( Z =7.82,6.33 ; P ＜ 0.05 ).The mean Lysholm scores were 93.8 ± 9.9 and 94.2 ± 9.6 and the mean Tegner scores were 6.6 ± 1.9 and 6.5 ± 1.7 for the double and single band groups,respectively( t =2.31,5.60,3.55,7.09 ;P ＜0.05 ).ConclusionArthroscopic measurement with a scale combined with other traditional methods to determine the tunnel location is easy to conduct and intuitional to understand.It could be useful in anatomic ACL reconstruction.

Objective To explore the ultrasound performance and related factors on the role of normal living rabbit's liver by laser ablation. Methods The rabbit's liver tissue were ablated by Echolaser integrated laser interventional ultrasound system, and the necrosis of the lesion and performance of pathology and anatomy were observed. Results The outline of the lesion was ellipse like. The two-dimensional US showed regular hyperecho area in the center, mild strong echo in the peripheral and mild attenuation backward. Contrast enhanced ultrasound (CEUS) showed a filling defect of contrast media in the ablated area. After dissection, the center of the lesion was slag-like carbon, the peripheral was necrosis area; HE staining showed: the center of the lesion was cavity like and dye-free,peripheral area was irregular red staining, the surrounding area was infiltrative inflammatory cells. Different power and time leaded to differences of the ablative effect and lesion size:the more power and time,the bigger of the ablative size. The ablative effect and lesion size was stable in 3 W 10 min and 5 W 6 min groups and caused the complete necrosis of the zone, there existed statistical differences among the two groups. Conclusions Laser ablation can cause fast, precise, effective and safe necrosis of the liver tissue, and the more power and time, the bigger of the ablative size.

Objective To explore the imaging features of liver tumors with real-time tissue elastography.Methods Eighty-five liver lesions in 67 cases were scanned with conventional ultrasonography and elastography using HI-Vision900 system and then assessed with grade scores.Results on ultrasound were compared with those on pathology.Results Majority of lesions with grade a-b on elastography were identified as benign on pathology, while most of masses with grade c-e on elastography were confirmed as malignant on pathology.The sensitivity, specificity and accuracy were 93.5%, 87.0% and 91.8% for elastography to detect malignant lesions,74.2% ,73.4% and 74.1% for conventional ultrasound.The Kappa value of two doctors on elastography in group Ⅰ (the depth of the lesion ≤10cm) was significantly higher than group Ⅱ (the depth of the lesion ＞10cm).Conclusions Real-time tissue elastography of liver tumors provides a new convenient,non-invasive diagnostic methods,contribute to identify the benign and malignant live tumors.

Objective To study the effect of high intensity focused ultrasound(HIFU)ablation on microvessel density(MVD)and vascular endothelial growth factor(VEGF)in rabbit hepatcocellular carcinoma (HCC)models.Methods The VX2 t umor cells were planted in the hepatic left-central lobe on 30 rabbits.All animals were divided into two groups randomly:HIFU group(n=25)and control group(n=5).The MVD and the expression of VEGF in the HCC was detected by immunohistochemical SABC methods in control group and 0,1,3.7,16 d after the operation in HIFU group.Results The MVD and the expression of VEGF in the HCC tissue after HIFU treatment in the HIFU group were decreased significantly as compared with those in the control group (P＜0.01).However,there was no significant difference in MVD and the expression of VEGF in the HCC tissue after HIFU treatment in the HIFU group among the different time points(P＞0.05).Conclusions HIFU treatment can effectively destroy the micovessel,repress the neovascularization and reduce the blood supply of the HCC.
