ABSTRACT
Objective To investigate whether endoscopic ultrasonography (EUS) can be an alternative method for diagnostic endoscopic retrograde cholangiopancreatography (ERCP) by comparing the ability of EUS versus CT and transabdominal ultrasonography (TUS) in the diagnosis of muddy stones of the common bile duct. Methods A prospective study was conducted for 53 patients suspected of muddy stones of the common bile duct who attended Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2019 to December 2021, and all patients underwent EUS, TUS, and CT before ERCP. With ERCP and endoscopic sphincterotomy (EST) for removing muddy stones of the common bile duct as the gold standard for the diagnosis of muddy stones of the common bile duct, EUS, TUS, and CT were compared in terms of their ability to display the muddy stones of the common bile duct. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. Results In the 53 patients, EUS, TUS, and CT had a positive rate of 88.68%, 50.94%, and 62.26%, respectively, in detecting muddy stones of the common bile duct. As for the positive results confirmed by EST under ERCP, EUS had a sensitivity of 93.75%, a specificity of 60.00%, and an accuracy of 90.57% in detecting muddy stones of the common bile duct, while TUS had a sensitivity of 56.25%, a specificity of 100.00%, and an accuracy of 60.38% and CT had a sensitivity of 66.67%, a specificity of 80.00%, and an accuracy of 67.92%. There was a significant difference between EUS and CT in the accuracy in detecting muddy stones of the common bile duct ( χ 2 =8.26, P =0.004), and there was also a significant difference in diagnostic accuracy between EUS and TUS ( χ 2 =13.05, P < 0.001). Conclusion EUS is more accurate than TUS and CT in the diagnosis of muddy stones of the common bile duct, and instead of ERCP, EUS is thus recommended for suspected muddy stones of the common bile duct when TUS and CT fail to identify the lesions in clinical practice, so as to make a confirmed diagnosis and reduce related costs and complications.
ABSTRACT
Objective To explore the clinicopathological characteristics,diagnosis,treatment and prognosis of accessory breast cancer.Methods Clinical and pathological data of 37 accessory breast cancer patients from Dec 2005 to Aug 2017 were reviewed.Results 12 patients underwent breast-conserving local wide excision plus axillary lymph node dissection.5 cases were treated by segmental resection and 19 patients by Auchincloss or Halsted mastectomy;One patient abandoned surgery.The most common histological type of accessory breast cancer was infiltrating ductal carcinoma (26 cases,70.3％) followed by adenocarcinoma (4 cases) and miscellaneous type (7 cases).The most common AJCC pathological stages were stage Ⅱ (n =24,65 ％),Ⅰ (n =8),Ⅲ(n =3) and Ⅳ (n =2).The median follow-up time was 6 (1-12) years,the followup rate was 100％.Until Dec 2017,7 patients died from metastasis and the others were alive.Conclusions Accessory breast cancer is rare and with poor prognosis.The diagnosis depends on clinical manifestations,imaging and pathology.Surgery is the mainstay therapy,adjuvant chemo therapy is recommanded.
ABSTRACT
Breast cancer is the most common malignant tumor in women. With the development of cell biology and molecular bio-technology, great progress has been made in the study of the pathogenesis of breast cancer. Familial breast cancer is closely related to the mutation of susceptible genes. Selected susceptible genes of breast cancer can be grouped into three categories: high-, medium-, and low-penetrance susceptible genes. The means of identifying the high-risk sites of pathogenic mutation and genetic polymorphism is the focus of research on the genetic predisposition of breast cancer.
ABSTRACT
Objective:To investigate the association between indoleamine 2,3-dioxygenase(IDO)expression in tumor tissue,its periph-eral blood activity, and the efficacy of neoadjuvant chemotherapyin patients with breast cancer. Methods: Immunohistochemistry (IHC)and high-performance liquid chromatography(HPLC)were used to measure IDO protein expression in tumor tissue,and kynuren-ine(Kyn),tryptophan(Trp),and IDO activity(Kyn/Trp)in peripheral blood before neoadjuvant chemotherapy in 53 patients with breast cancer from Tianjin Medical University Cancer Institute and Hospital between September 2015 and December 2016.The correlations between the expression and activity of IDO and the efficacy of chemotherapy were analyzed.Results:In tumor tissue,IDO expression-before neoadjuvant chemotherapy was related to clinical tumor stages(P=0.006),node stages(P=0.020),clinical stages(P=0.045),and estrogen receptor(ER)status(P=0.014).High IDO activity before neoadjuvant chemotherapy in peripheral blood was associated with high IDO expression in tumor tissue(P=0.004),and was also correlated with clinical tumor stages(P=0.019)and node stages(P=0.047). Univariate analysis showed that the clinical efficacy of neoadjuvant chemotherapy was associated with pre-chemotherapeutic clinical tumor stages(P=0.049),ER status(P=0.025),and molecular subtype(P=0.014),while pathologic complete response(pCR)was related to pre-chemotherapeutic clinical tumor stages(P=0.014).Importantly,the clinical efficacy of neoadjuvant chemotherapy and pCR were both related to IDO expression and activity before chemotherapy(all P<0.05).Multivariate analysis showed that pre-chemotherapeu-tic IDO activity in peripheral blood was the only independent factor that affected pCR(P=0.032).Conclusions:Tumor tissue IDO expres-sion and peripheral blood IDO activity before chemotherapy were associated with chemotherapy efficacy,and could provide promising information for the clinical prediction of chemotherapy sensitivity.
ABSTRACT
Objective:To search the English literatures on prescription refills for chronic diseases for a systemic analysis and to explore the mode and the management measures in order to develop the prescription refill and medication therapy management service for patients with chronic diseases in China .Methods:In the pubmed database , the literatures related to prescription refills published before April 2016 was retrieved.The literatures were analyzed by classification of country or region , the types of drugs and the other in-formation.Results:It was found that the United States , Britain and Sweden were the countries with the most prescription refills .The medications for hypertention , diabetes , hyperlipidemia and other chronic diseases respectively were the most types of medications men -tioned.Age, educational level, race, language, type of medication, and so on.were the factors that affected patient compliance . Pharmacists played a role in auditing , intervention and follow-up in prescription refills programs .Conclusion: The programs of pre-scription refills is well developed in America and Europe , which may be a good way to solve the demand in long-term caremedication therapy for those patients in China .
ABSTRACT
Repeat prescription is adopted in Singapore as a convenient measure for patients with chronic diseases.On the one hand, it can avoid patients''inconvenience caused by frequent visits to hospitals.On the other hand, it reduces the waste of medical resources.In recent years, Singapore has also been using modern technology and measures to expand the medication refill service actively in order to enhance work efficiency, reduce waiting time and promote drug safety, thus to improve patients'' satisfaction.With the increasing medical pressure and the deepening of medical reform, the repeat prescription model in Singapore shows positive enlightenment to China.
ABSTRACT
OBJECTIVE: The purpose of this study was to develop a motivation-enhancing self-management program and apply to rural aged with hypertension to evaluate the applicability of the Program. METHODS: The motivation-enhancing self-management program was on the evidence of Orem's self-care theory and Ford's Motivational system theory which consists of group education and tele-coaching conducted 12-week. The program evaluation was done by structured questionnaires of motivation (self-efficacy, perceived benefit, perceived barrier and emotional salience), self-care and blood pressure. There were totally 31 aged with hypertension in 2 rural areas enrolled in the program. RESULTS: There was only perceived benefit statistically significant between the intervention and control group (t=2.05, p=.04) and self-care level was no difference between the two groups (t=0.21, p=.84) after program. But there are statistically significant differences of systolic blood pressure between the intervention and control group(t=-2.62, p=.01). CONCLUSION: The motivation-enhancing self-management program is necessary for the rural aged with hypertension, but it's needed modify and revise in the future study.
