Objective To evaluate the clinical application value of transesophageal atrial pacing (TEAP) combined with atropine load experiment in the diagnosis of the lesions of sinoatrial node and atrioventricular node.Methods One hundred and forty-four cases selected from the outpatient and hospitalized patients in the People's Hospital of Changji Hui Autonomous Prefecture from September 2009 to December 2012,who with dizziness, syncope and other clinical symptoms and electrocardiogram showe.TEAP combined with atropine load experiment were given to these patients.Results (1) The authors detected in all patients,83 cases (57.6％) were positive, among which, 48 cases (57.8％) male, 35 cases (42.2％) female.(2) The authors detected 57 cases(39.6％) non-increased vagus nerve tension cases in 83 positive cases,among which 33 cases (57.9％) male, 24 cases (42.1％) female;Among which 29 cases (20.1％) were sinoatrial node hypofunction, and 16 cases(55.2％) male;8 cases(5.6％) were atrioventricular node hypofunction,and 4 cases(50％) male;14 cases(9.7％) were double node hypofunction, and 10 cases (71.4％) male;6 cases (4.2％) were tachycardia-bradycardia syndrome, and 3 cases (50％) male;among which, a long interval of greater than 3 seconds appeared when we stimulate one 84 years old man with S1S1 stimulate way, immediately pressed protective pacemaker until his own sinus rhythm was restored, as a safety precaution, stoped further examination and classified him as sick sinus group.Conclusion Detect the common causes of slow sinus and atrioventricular block,such as the sinoatrial node dysfunction, atrioventricular node dysfunction, double node dysfunction and increased vagus nerve tension through TEAP combined with atropine load experiment.Consider that this methods have the best diagnostic value in decreasing its rate of false positivity,and should be used as a necessary check before implantation of pacemaker in such patients, suitable used in clinical, especially in basic general hospitals.

AIM To observe the clinical efficacy of Maixuekang Capsules (hirudin) combined with female progestational hormone treating blood-stagnated cryptogenic hypomenorrhea and their mechanism of action.METHODS Ninty eligible patients were randomly and equally divided into treatment group (Maixuekang Capsules combine with female progestational hormone) and control group (female progestational hormone),treated for three menstrual cycles,the menstrual blood volume,blood D-dimer,maximum platelet aggregation rate,the thickness of endometrium,spiral artery blood flow peak systolic velocity (PSV),resistance index (RI) and pulsatility index (PI) were recorded during the three months period.RESULTS The menstrual blood volume of the two groups were all increased post-treatments (P ＜ 0.05),the treatment group was superior to the control group (P ＜ 0.05);blood D-dimer and maximum platelet aggregation rate of the treatment group had reduced post-treatments (P ＜ 0.05),there was no difference in the two values of the control group between post-treatment and pre-treatment (P ＞ 0.05);the thickness of endometrium of the two groups were both increased after the treatment (P ＜ 0.05),while there was no remarkable statistical difference between the two groups (P ＞ 0.05);RI in the treatment group had remarkable reduction post-treatments (P ＜ 0.05),but there was no remarkable difference of RI in the control group (P ＞ 0.05);there was no statistical difference of PSV and PI in both groups before and after the treatment (P ＞ 0.05).CONCLUSION The combination treatment of Maixuekang Capsules and female progestational hormone can obviously increase menstrual blood volume,improve uterine blood perfusion and endometrial microcirculation.It has more advantages than use hormones alone.

The principles of step by step, the combination of practice and theory, the co-existing of being implicit and explicit, the equality between guidance and autonomous can be followed to construct humanities curriculum system in content, resources, teaching staff and teaching in medical colleges for nationalities. Furthermore, humanities curriculum system must insist on a fundamental concepts that the human theory is the essence of medicine, and the humanities is the basic structure of medicine and the key to success is the training of humanities teachers.

Objective To investigate the prognostic value of different stages of TNM in patients with appendiceal neuroendocrine tumors (NETs). Methods The clinical data of 40 cases of NETs were analyzed, and follow-up data were staged by the ENETS and AJCC TNM staging system. Kaplan-Miere survival curves were used to compare survival differences in patients with different stages of TNM. Results Of the 40 patients, no one was diagnosed as appendiceal NETs before surgery. Twenty-one patients were diagnosed as acute appendicitis, 16 were diagnosed as chronic appendicitis and 3 were suspected as appendiceal tumors due to thickening of the lumen before surgery. No clinical manifestations were found in 40 patients before surgery including diarrhea, abdominal pain, facial flushing, asthma-like seizures and other carcinoid syndrome performance. All patients underwent appendectomy, and appendix NETs were diagnosed by pathology after surgery. In 40 appendical NETs patients, 15 cases were classified as stageⅠ(37.5%), 10 cases were classified as stageⅡA (25%), 2 cases were classified as stageⅢA (5%), 13 cases were classified at stageⅢB (32.5%), and no patients were classified as stageⅣ. The median survival times (months) were 27, 22, 21 and 18 for patients with different stages, and there were no significant differences in survival times between four stages (χ2=0.8988,P>0.05). Conclusion The clinical features of appendical NETs are nonspecific. The diagnosis of appendical NETs is based on pathological examination and immunohistochemistry. There are no correlation between different TNM stages and prognosis of patients.

PURPOSE: The purpose of this study is to determine whether the new pulmonary valve reconstruction technique prevents short-term postoperative pulmonary regurgitation and improves early and mid-term clinical outcome. METHODS: We reviewed postoperative echocardiographic variables and chest X-ray films from 31 patients who had undergone valve reconstruction(pulmonary valve reconstruction group:PVR) for the repair of TOF between April 2000 and August 2004. We compared the clinical data of these patients with those from 47 patients who had right ventricular outflow tract reconstruction with a monocusp valve(monocusp ventricular outflow patch group:MVOP) and 22 patients who had a transannular patch repair without a monocusp valve(transannular patch group:TAP). RESULTS: In the PVR group, 25 patients(81 percent) had trivial or mild pulmonary regurgitation in their early post operative echocardiogram. Only 12 patients(26 percent) in the MVOP group had mild pulmonary regurgitation; and no patient in the TAP group had it. Pulmonary valve function was good in 96 percent of the PVR group, 36 percent of the MVOP group, and none in the TAP group in early post-operative echocardiogram. Follow-up echocardiogram(1, 2, 3, 4 years later) of the MVOP and TAP groups showed moderate pulmonary regurgitation and severely decreased valve function in almost all cases. However, in the PVR group 54 percent(16/28), 50 percent(14/28), 37 percent(9/24), and 31 percent(5/16) of the patients had trivial or mild pulmonary regurgitation 1, 2, 3 and 4 years after operation, respectively. The valve function remained good in 80 percent(24/30), 64 percent(18/28), 57 percent(12/21), and 31 percent(5/16) of the patients 1, 2, 3 and 4 years after operation respectively. CONCLUSION: Pulmonary valve reconstruction is effective in reducing pulmonary regurgitation and right ventricular dilatation in the repair of TOF, even though regurgitation increases with time. Further study is needed to determine long-term results.

BACKGROUNDPneumonia is the most common cause of morbidity and mortality in lung transplant (LT) recipients. The aim of the present study was to evaluate the incidence, etiology, risk factors and prognosis of pneumonia in LT recipients.

METHODSThe LT cohort consisted of 28 recipients receiving LT in Beijing Chao-Yang Hospital from August 2005 to April 2011. Data collected included demographic data, underlying disorders, time and type of transplant, follow-up information, date of last follow-up, and patient status. A retrospective analysis was made of observational data that were prospectively collected.

RESULTSTwenty-two patients of 28 LT recipients had 47 episodes of pneumonia throughout the study period. Thirtyeight episodes of pneumonia in 19 recipients occurred post-LT with a median follow-up of 257.5 days (1-2104 days), the incidence of pneumonia was 192.4 episodes per 100 LT/year and its median time of onset was 100.5 days (0-946 days) post-transplantation. Bacteria, virus and fungi accounted for 62%, 16% and 15% of the microbial pathogens, respectively. The most frequent were Pseudomonas aeruginosa (20%), cytomegalovirus (CMV) (15%), and Aspergillus fumigatus (10%). A total of 29% (11/38) of pneumonias occurred in the first month post-LT, and then the incidence decreased gradually. The incidence of CMV pneumonia was 25% (7/28) with a median time of 97 days (10-971 days). More than one bacterial infection and CMV infection were independent risk factors for aspergillus infection. The incidence of pulmonary tuberculosis (TB) was 18% (5/28), and the history of TB was a risk factor for TB relapse. There were 58% (7/12) of recipients who died of infection, and 71% (5/7) of these died in the first year after LT.

CONCLUSIONSPneumonia is still a major cause of morbidity and mortality in LT recipients. The most frequent microorganisms were Pseudomonas aeruginosa, CMV, and Aspergillus fumigates. The incidence of CMV pneumonia decreases with a delayed median time of onset. More than one incidence of bacterial infection and CMV infection are independent risk factors for aspergillus infection. LT recipients are at high risk for TB, and the history of TB is a risk factor for TB relapse.

OBJECTIVETo investigate the impact of heart valve calcification (HVC) on cardiovascular outcomes in patients on maintenance hemodialysis (MHD).

METHODSWe enrolled 302 Chinese patients on MHD between 2009 and 2011 including 99 with HVC identified by echocardiography screening. All the patients were followed up for 2 years and survival analysis was performed with all-cause mortality, cardiovascular mortality and new onset cardiovascular events as the endpoints. Cox regression analysis was used for analyzing the impact of heart valve calcification on the cardiovascular outcomes of the patients.

RESULTSThe mean age of the total patients was 58.2∓15.0 years when receiving the initial MHD, and 53.6% were male patients. The overall mortality, cardiovascular mortality and new on-set cardiovascular events in HVC and non-HVC groups were 30.3% vs 16.3%, 22.2% vs 6.9%, and 48.5% vs 25.6%, respectively (P<0.05). Kaplan-Meier survival analysis showed a significant difference in all-cause mortality (P=0.006), cardiovascular mortality (P<0.001) and new-onset cardiovascular events (P<0.001) between HVC and non-HVC groups. After adjustment, Cox regression analysis identified HVC as a risk factor for increased all-cause mortality (HR=1.88; 95%CI: 1.11-3.19), cardiovascular mortality (HR=3.47, 95%CI: 1.76-6.84) and cardiovascular events (HR=1.64, 95% CI: 1.09-2.47).

CONCLUSIONSHVC is an independent risk factor for increased cardiovascular mortality and new cardiovascular events in patients on MHD.

Adult-onset Still's disease (AOSD) is a rare but clinically well-known, polygenic, and systemic autoinflammatory disease, which is characterized by spiking fever, evanescent skin rash, arthralgia, and sore throat. The application of non-steroidal anti-inflammatory drugs and glucocorticoids, which are first-line therapies of AOSD, is limited due to their side effects such as liver injury or disorder of blood glucose. Therefore, patients who suffer from systemic diseases in China prefer to seek help from Chinese herbal medicine (CHM), which is an important part of complementary and alternative medicine. In this case, we report a 28-year-old male badminton coach presenting with a 15-day history of fever and skin rash, accompanied by sore throat, fatigue, myalgia and chills. Additionally, hepatosplenomegaly, multiple lymphadenopathies, aminotransferase abnormality, and elevated inflammatory factor levels were observed during hospitalization. Infectious diseases, solid tumors, hematological diseases, and common autoimmune diseases were excluded. Not benefitting from antibiotic therapy, the patient was finally diagnosed with AOSD, after a careful examination, then showed rapid remission after a six-week treatment with CHM granules based on Xiaochaihu Decoction and Yinqiao Powder. After stopping the treatment, there was no relapse within a 15-month follow-up period. To the best of our knowledge, this is the first well-documented case of this successful treatment. The present case report suggests that CHM is a reliable choice for complementary and alternative therapy for AOSD, but confirming the utility of CHM for AOSD requires further support from prospective studies.
