ABSTRACT

<p><b>BACKGROUND</b>Ovarian cancer is the most common cause of gynecological cancer-associated death. Iatrogenic menopause might adversely affect the quality of life and health outcomes in young female cancer survivors. We evaluated whether postoperative hormone replacement therapy (HRT) had a negative influence on the progression-free survival (PFS) of patients with papillary serous ovarian cancer (SOC).</p><p><b>METHODS</b>We retrospectively reviewed the medical records of patients with papillary SOC, treated from January 1980 to December 2009, who suffered from menopause with or without HRT. Clinical characteristics of patients were compared between the two groups (HRT and non-HRT). Blood samples were collected from all the participants to detect serum cancer antigen (CA) 125. Hazard ratios with 95% confidential intervals for each variable were calculated by univariable and multivariable conditional Logistic regression analyses.</p><p><b>RESULTS</b>Among 112 identified patients, 31 were HRT users and 81 were not. The two groups did not significantly differ in median age at diagnosis (t = 0.652, P = 0.513), International Federation of Gynecology and Obstetrics (FIGO) stage (χ2 = 0.565, P = 0.754), differentiation (χ2 = 1.728, P = 0.422), resection status (χ2 = 0.070, P = 0.791), relapse (χ2 = 0.109, P = 0.741), chemotherapy course (t = -1.079, P = 0.282), follow-up interval (t = 0.878, P = 0.382), or PFS (t = 0.580, P = 0.562). Median Kupperman score at the onset of HRT was 30.81 and 12.19 after the therapy (t = 3.302, P = 0.001). According to the analysis, the strongest independent variables in predicting PFS were FIGO stage and disease that was not optimally debulked.</p><p><b>CONCLUSIONS</b>Postoperative HRT is not a prognostic factor for PFS of patients with papillary SOC. However, multicenter studies are needed to verify and extend our findings.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the technical characteristics and application of mass casualty incident (MCI) primary triage (PT) methods applied in China.</p><p><b>DATA SOURCES</b>Chinese literature was searched by Chinese Academic Journal Network Publishing Database (founded in June 2014). The English literature was searched by PubMed (MEDLINE) (1950 to June 2014). We also searched Official Websites of Chinese Central Government's (http://www.gov.cn/), National Health and Family Planning Commission of China (http://www.nhfpc.gov.cn/), and China Earthquake Information (http://www.csi.ac.cn/).</p><p><b>STUDY SELECTION</b>We included studies associated with mass casualty events related to China, the PT applied in China, guidelines and standards, and application and development of the carding PT method in China.</p><p><b>RESULTS</b>From 3976 potentially relevant articles, 22 met the inclusion criteria, 20 Chinese, and 2 English. These articles included 13 case reports, 3 retrospective analyses of MCI, two methods introductions, three national or sectoral criteria, and one simulated field testing and validation. There were a total of 19 kinds of MCI PT methods that have been reported in China from 1950 to 2014. In addition, there were 15 kinds of PT methods reported in the literature from the instance of the application.</p><p><b>CONCLUSIONS</b>The national and sectoral current triage criteria are developed mainly for earthquake relief. Classification is not clear. Vague criteria (especially between moderate and severe injuries) operability are not practical. There are no triage methods and research for children and special populations. There is no data and evidence supported triage method. We should revise our existing classification and criteria so it is clearer and easier to be grasped in order to build a real, practical, and efficient PT method.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the clinical effect of thoracolumbar fractures between single-segment pedicle screw fixation approach for the gap of paravertebral muscles and double-segment pedicle screw fixation approach for the stripping of paravertebral muscles.</p><p><b>METHODS</b>From September 2008 to January 2010, 65 patients with incomplete compressed thoracolumbar fractures or burst thoracolumbar fractures with unilateral endplate injury were randomly divided into two groups. Thirty patients were treated with single-segment pedicle screw fixation through the gap of paravertebral muscles (treatment group). Thirty-five patients were treated with double-segment pedicle screw fixation through the stripping of the paravertebral muscles (control group). All the internal fixations were taken out during 10-12 months after operation. Operative time, perioperative blood loss volume and postoperative drainage volume were compared between two groups. At final follow-up, the change of neurological ASIA grade were recorded; and postoperative 5 days and final follow-up, compared Denis classification of lumbar and back pain between two groups; and analyzed the sagittal index and compressibility of anterior border of vertebral body by X -ray lateral projection.</p><p><b>RESULTS</b>All patients were follow-up from 14 to 22 months with an average of 18.3 months. No postoperative infection, secondary spinal cord injury was found. One case of control group occurred internal fixation breakage at the 11th month after operation and other internal fixation no loosening. There was no significant difference in operative time, the recovery of neurological function between the two groups (P > 0.05). Perioperative blood loss volume and postoperative drainage volume of treatment group was less than that of control group (P < 0.01). And in Denis classification of lumbar and back pain, the treatment group recovered more quickly, and the residual pain of lumbar and back was less than that of control group (P < 0.01). Postoperative posterior salient and compression of anterior border of vertebral body improved in two groups (P < 0.01), there was no significant difference in degree of improvement between two groups (P > 0.05); but both loss existed at final follow-up (P < 0.01), there was no significant difference in loss of posterior salient between two groups (P > 0.05). In the treatment group, the loss of rectify of anterior border of vertebral body existed, but it was less than that of the control group.</p><p><b>CONCLUSION</b>In the premise of strict controlling surgery indications, the treatment of thoracolumbar fractures with single-segment pedicle screw fixation through the gap of paraspinal muscles, can effectively recover the height of vertebral body and rectify posterior salient, and reduce the fixed segment. Compared with the traditional operative method of double-segment pedicle screw fixation through the stripping of paraspinal muscle, it can obviously reduce the operation wound and the bleeding, lessen the pain of lumbar and back. And the recent clinical effect is satisfied.</p>

ABSTRACT

Objective To establish and verify the prediction model for ischemic cardiovascular disease(ICVD)among the elderly population who were under the current health care programs. Methods Statistical analysis on data from physical examination, hospitalization of the past years, from questionnaire and telephone interview was carried out in May, 2003. Data was from was randomly selected to generate both module group and verification group. Baseline data was induced to make the verification group into regression model of module group and to generate the predictive value. Distinguished ability with area under ROC curve and the predictive veracity were verified through comparing the predictive incidence rate and actual incidence rate of every deciles group by Hosmer- Lemeshow test. Predictive veracity of the prediction model at population level was verified through comparing the predictive 6-year incidence rates of ICVD with actual 6-year accumulative incidence rates of ICVD with error rate calculated. Results The samples included 2271 males over the age of 65 with 1817 people for modeling population and 454 for verified population.All of the samples were stratified into two layers to establish hierarchical Cox proportional hazard regression model, including one advanced age group(greater than or equal to 75 years old), and another elderly group(less than 75 years old). Data from the statically analysis showed that the risk factors in aged group were age, systolic blood pressure, serum creatinine level, fasting blood glucose level, while protective factor was high density lipoprotein; in advanced age group, the risk factors were body weight index, systolic blood pressure, serum total cholesterol level, serum creatinine level, fasting blood glucose level, while protective factor was HDL-C. The area under the ROC curve (AUC)and 95%CI were 0.723 and 0.687-0.759 respectively. Discriminating power was good. All individual predictive ICVD cumulative incidence and actual incidence were analyzed using Hosmer-Lemshow test, x 2=1.43, P=0.786, showing that the predictive veracity was good.Conclusion The stratified Cox Hazards Regression model was used to establish prediction model of the aged male population under a certain health care program. The common prediction factor of the two age groups were: systolic blood pressure, serum creatinine level, asting blood glucose level and HDL-C. Thc area under the ROWC curve of the verification group was 0.723, showing that the distinguished ability was good and the predict ability at the individual level and at the group level were also satisfactory. It was feasible to using Cox Proportional Hazards Regression Model for predicting the population groups.

ABSTRACT

Objective To investigate the 6-year accumulative incidence rate of ischemic cardiovascular disease (ICVD) and its related risk factors. Methods Baseline population was all from an elderly population with members all born before 1-1,1938 and under health care programm.Data was recorded in a database of a hospital and baseline of subjects under research was aged >65years. People that had had ICVD at baseline were excluded. Risk factors under research would include: age at the baseline study, gender, body mass index, systolic blood pressure, serum cholesterol level, serum triglyceride level, serum high-density lipoprotein level, serum triglyceride level, serum apolipoprotein A1 level, history of diabetes mellitus and cigarette smoking etc. Single factor analysis was carried out using person-years as time of study, then calculating the person-year incidence and the accumulative incidence rate at different levels related to baseline risk factors.Multivariate analysis was under Cox Proportional Hazards Regression Model. Results Baseline population included 2271 elderly men, with the 6-year cumulative prevalence rate of ICVD as 23.56%, and the person-year prevalence rate was 45.41‰. Single factor analysis showed that the ICVD events positively related to variables which including systolic blood pressure, body mass index,serum cholesterol level and serum triglyceride level, serum apolipoprotein A1 level, status of diabetes mellitus and cigarette smoking. The ICVD events negatively related to variables as serum high-density lipoprotein levcl and serum creatinine level. Results of multivariate analysis showed that high systolic pressure, diabetes mellitus, serum creatinine level, Body Mass Index were the main risk factors. The serum high-density lipoprotein level served as the main protective factor. Conclusion The aged male population under health care programme was high in the ICVD prevalence rate, suggesting that programmes as controlling blood pressure, blood glucose, and increasing serum high-density lipoprotein levels were effective measures to decrease the ICVD events.

ABSTRACT

Objective: This study aims to investigate whether postoperative adjuvant chemotherapy had any influence on the survival rate of those women with early ovarian carcinoma who did not receive pelvic lymphadenectomy and secondary surgery. Methods: This work conducted a retrospective review on all apparently stage I epithelial ovarian carcinoma patients who had not undergone lymphadenectomy in Queen Mary hospital, Hong Kong, within a ten-year period, from January of 1992 to December of 2002. Results: This work collected the clinical data from 81 patients. Twenty-three patients were apparently at stage IA, 1 patient at stage IB, and 57 patients at stage IC. The mean age was 47 years old (21-81 years) and the median follow-up period was 110 months (50-179 months). Totally 64 (79.0%) patients received adjuvant chemotherapy. The 5-year overall survival rate was 91.4% and 4-year progression free survival rate was 85.2%, which were similar to the survival rates described in the literature for patients who had undergone systematic lymphadenectomy. Conclusion: With provision of appropriate adjuvant chemotherapy, women with apparent stage I disease who have not undergone pelvic lymphadenectomy may achieve similar long-term survival rate to those who have undergone systematic lymphadectomy.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of Lidan Granule (, LDG) on bile lithogenic tendency and biliary 33.5 kd vesicular protein (VP) and to explore its mechanism.</p><p><b>METHODS</b>Sixty patients with choledocholithiasis combined with cholecystolithiasis were randomly assigned to the LDG treated group, the sodium cholate treated group for positive control, and the untreated control group, 20 patients in each group. The 4 bile lithogenic trend indexes, including lithogenic index (LI), unconjugated bilirubin percent (UCB%), unconjugated bilirubin saturation index (BSI) and Z-value, were determined before and after treatment. The content of VP in bile was determined as well.</p><p><b>RESULTS</b>Before treatment, the LI, UCB%, BSI and Z-value in the LDG treated group were 1.298+/- 0.265, 34.72+/-2.96, 0.353+/-0.093 and 0.556+/-0.499, respectively, which was decreased after the 2-week treatment to 0.926+/-0.208, 8.93+/-1.19, 0.154+/-0.056 and 0.257+/-0.211, respectively (all P<0.05). Meantime, the content of VP was also lowered from 0.050+/-0.005 g/L to 0.032+/-0.005 g/L. However, no significant change in any of the above-mentioned indexes was found in the other two groups.</p><p><b>CONCLUSION</b>LDG could effectively suppress bile lithogenic trend and reduce 33.5 kd VP in bile.</p>
