Hepatic surgery has got fast development during recent years. Hepatic anatomic complexity is not the fence of hepatic surgery development. The limit of liver function reserve controls hepatic operation and makes surgeons confused. The investigation of hepatic function reserve has made great prograsses recently. This article reviewed domestic and overseas documents to explain the contrilmtion of liww functional reselwe examination for hepatic surgery on the basis of hepateetomy quantity, tumor postoperative relapse, liver transplantation , liver function failure and liver function reserve detection.

Objective Intestinal obstruction is a frequent sequela of recurrent ovarian cancer and difficult to deal with We analyzed a series of such patients to determine if their outcomes have changed after undergoing palliative surgery Method We retrospectively reviewed 67 patients undergoing surgery for intestinal obstruction due to recurrent ovarian carcinoma and 75 patients receiving non surgical treatmen from 1997 to 2002 Results During the study period,67 operations were performed on 67 patients Among them,surgical procedure was completed in 58 cases Successful palliation was achieved in 64 2% of cases in which surgical correction was possible The median survival of the entire cohort was 7 8 months,and 12 6 months for the surgically successfully relieved patients and 3 7 months for those non surgical patients The rate of major surgical morbidities was 22 4 % The perioperative mortality rate was 6 0% Successful palliation was associated with the absence of two prognostic factors:multiple obstructive sites and palpable abdominal and pelvic masses Conclusion Palliative surgery for bowel obstruction in recurrent ovarian cancer can be worthwhile,and properly selected patients are the key to its success

Objective To assess the value of tomographic ultrasound imaging (TUI) for prenatal analysis of the relative orientation of fetal heart and great arteries. Methods Volume datasets acquired from 12 patients of transposition of the great arteries (TGA) and 13 normal fetal heart were evaluated offline with TUI. The aortic valves (AV) and pulmonary valves (PV) were respectively showed on the two parallel slices. According to the pivot point in the middle of the PV in one slice, the relative orientation of the AV on another slices were analyzed. Results In the 12 patients of TGA confirmed postnatally, 7 were concomitant with single ventricle anomaly, AV was on the anterior-right orientation of the PV in 5, and was relatively on the anterior and anterior-left orientation in other 2 of them.In the remained 5 with seeming normal 4 chamber view, AV was found on the anterior-right of the PV in 3, and was relatively on the anterior and upright orientation.in other 2 patients. In 13 normal fetuses, TUI showed that all AV located on the posterior-right orientation to the PV. Conclusion TUI can provide detailed spatial information of the great arteries both in normal and abnormal fetal heart. It may be a convenient and veracious tool for prenatal exploring the morphology of the great arteries.

OBJECTIVE: To test the reliability and validity of Health Scale of Traditional Chinese Medicine (HSTCM) by means of questionnaires. METHODS: A cross-sectional survey was conducted at Liwan Community of Guangzhou, Old People's Home in Guangzhou and Outpatient Department of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine. A total of 652 Chinese individuals (over 18 years old) were assessed with the 88-item version of HSTCM and World Health Organization Quality of Life Measure-Abbreviated Version (WHOQOL-BREF), which were randomly delivered to them. Some socioeconomic characteristics were registered. RESULTS: A test-retest reliability (15-day interval) was found among the 76 persons who completed the questionnaires by themselves. Intra-class correlation coefficient (ICC) was 0.93. Associated 95% confidence interval (CI) was 0.89-0.96. Split-half reliability was 0.79. Inter-investigator reliability (0.93) was also good, and the ICC of HSTCM was 0.90 (95%CI 0.67-0.97). The correlation between HSTCM and WHOQOL-BREF was -0.66. The correlations of HSTCM and questionnaire deliver order, investigator, interview date and interview time were 0.06, -0.12, -0.17 and 0.20 respectively. The correlation between HSTCM and self-rated health (0.46) was greater than that between HSTCM and chronic illness (0.28). Divided by individuals with or without chronic illness, area under the ROC (receiver operator characteristic) curve for HSTCM was 0.67 (95%CI 0.63-0.71). CONCLUSION: It indicates that the HSTCM is conceptually valid with satisfactory psychometric properties and forms a basis for further applications in clinical research of traditional or integrative medicine.

Objective To preliminary investigate fetal left heart function of fetuses in α-thalassemia using spatio-temporal image correlation (STIC).Methods 95 volumes from fetal hearts in singleton pregnancies at 20-28 weeks of gestation were collected.STIC datasets were frozen in end-systole and enddiastole.Ventricular volumes were measured using VOCAL,Inversion and SonoAVC.The stroke volume was calculated from these measurements.Results All data sets could be measured with all three techniques in this study.The intraclass correlation coefficients (ICCs) between techniques were all ＞ 0.90.The time necessary to measure the stroke volume was significantly shorter using SonoAVC than using VOCAL and Inversion.Bland-Altman plots showed no clinically significant mean percent differences between stroke volume measurements obtained from each ventricle using three techniques.The left ventricular end-systole volume(ESV),stroke volume(SV)and ejection fraction(EF)was significantly different than fetuses with normal heart (P ＜ 0.05).Conclusions This study shows the feasibility of measuring left ventricular volumes during either systole or diastole and thereby calculating stroke volumes with all three techniques.And there was a high degree of reliability for all three techniques,as shown by excellent ICCs.There was good accuracy of STIC techniques in measuring fetal left ventricular volumes with cardiomegaly.

Odor and taste are characteristic properties of traditional Chinese medicine (TCM). They are closely related to the chemical compositions in TCM. They are also the outer reflection of TCM quality and an important part of the character identification. This article reviewed the current research on odor and taste identification of TCM, which indicated that odor and taste identification had not been paid enough attention to and its research lagged behind modern social development. Based on current analytical techniques and methods, this article proposed a new idea for odor and taste identification of TCM. The idea emphasized the objectification of odor and taste and TCM identification research should be combined with chemical components analysis.

Objective To explore the diagnosis and treatment of gastrointestinal stromal tumors(GISTs).Methods Clinical and pathological data of the 32 GISTs cases treated over the recent 5 years in our hospital were reviewed retrospectively.Results Stomach was the most frequent site for GISTs.Abdominal pain was the most common symptom.Before operation,81.3%(26/32) of the cases were misdiagnosed.All of the cases underwent surgical resection.10 recurrent GIST patients received a second resection,and 8 patients(underwant) three or more resections.Follow-up was made from six months to 5 years,and 8 patients died.Conclusions The diagnosis of GISTs is difficult and mainly depends on histopathology and(immunohistochemistry).Surgical resection is the principal treatment of GISTs.Reoperation is effective for the treatment of recurrent cases.

To select appropriate descriptors for responses of the Health Scale of Traditional Chinese Medicine (HSTCM).

Objective:To study the effects of periodontal scaling on microorganism in periodontal pocket and gingival crevicular fluid in patients with periodontitis.Methods:60 cases of periodontitis were selected and divided into 2 groups randomly with 30 in each group.The patients in scaling group were treated by periodontal scaling, those in control group by gargle with chlohexidine.Before and after treatment the microorganism in pocket bottom of each patient was measured by Congo red negative dyeing.Gingival index(GI), probing depth(PD) and gingival crevicular fluid(GCF) were also measured, the relationship between periodontal scaling and clinical indices was analysed.Results:In scaling group the percentage of coccoid cells in pocket bottom increased more after scaling,that of bacillus,spirochetes decreased, PD,GCF value were all decreased (P0.05).Conclusion:Periodontal scaling can decrease the percentage of pathogenesis bacteria in periodontal pocket bottom and decrease PD,GI and GCF values.

Objective To discuss the feasibility and reproducibility of left ventricular volume and function of patients with left atrial remodeling and left ventricular remodeling by 3-dimensional echocardiography HeartModel (3D-HM).Methods Three-dimensional images of 156 subjects were collected under HMACQ imaging mode.They were assigned into three groups:① control group (group A,n =70);② group of left ventricular remodeling after,acute myocardial infarction (group B,n =17);③group of hypertension left atrial remodeling (group C,n =69).3D-HM method was used for quantifying left ventricular end-diastolic volume (LVEDV),left ventricular end-systolic volume (LVESV),left atrial end-systolic volume (LAESV) and left ventricular ejection fraction (LVEF),and the results were compared with conventional 3D-manual results.The reproducibility of the 3D-HM method within one group and among different groups was evaluated.Results There was a significant difference in all the parameters measured with the 3D-HM method in different groups(P ＜0.05).LVEDV,LVESV,and LAESV in group B were higher than those in group A and group C(P ＜0.05),and LVEF was lower than that in group A and group C(P ＜0.05),LAESV of group C was higher than that of group A(P ＜0.05).The difference in the measurements of LVEDV and LVESV between the two methods was greatest in group B compared with group C and group A(P ＜0.05).In group C,the measured value difference of LAESV between two methods was greater than that of group A (P =0.03).There was closer correlation among LVEDV,LVESV,LAESV and LVEF measured values of 3D-HM method as well as measured values of the 3D-manual method (r =0.94,0.97,0.91 and 0.90).The data post-processing time of 3D-HM was significantly shorter than that of 3D-manual (P ＜0.05).The inter-observer and intra-observer difference of measured values of 3D-HM method had no statistical significance (P ＞0.05).Conclusions 3D-HM is a fast and feasible technique with high reproducibility for quantifying the left ventricular volume and function in patients with left atrial remodeling and left ventricular remodeling.
