The serum activities of 3 cytokines (TNF,IL-1 and IL-6) were observed in 23 patients admitted within 4 days of onset of acute pancreatitis (AP). The results showed that the serum level of 3 cytokines raised in all of the AP patients, significant difference between TNF and IL-1 was abserved at admission and IL-6 did after one week of admission, suggesting that proper cytokine criteria are useful in predicting severity of the disease but the relationship between cytokines and MOF had not established.
Objective To investigate and analyze the past and on-going pro-poor programs related to health equity, and the relevant policies, documents, interventions measures, etc. to improve the China prisoners’ accessibility and utilization of tuberculosis (TB) control services in TB control programs, then evaluate their impacts and influences to provide evidences and suggestions for the further work of TB prevention and treatment. Methods Retrieve published documents about TB prevention and treatment of transient population dating from 1998 to 2008 from MEDLINE, PubMed, CNKI, CBMdisc CDDB and VIP with computers. Simultaneously, a series of interviews was conducted after we got the agreement of the interview people by using non-probability statistics methods. Results A total of 23 documents were retrieved, and they were consonant with the criteria, among which 8 were published and 5 were policy documents. The study on the second document showed the measures that presently applied on TB patients among prisoners in China: find patients through surveys, inspect every prisons and patients going to visit doctors with symptoms; concerning differences between various groups of prisoners, the measure of “classify and instruction, enroll together and treat” was applied; carry out health education in the prisons and so on. After the implement of various measures, the knowledge awareness, discovery rate, accomplishment ratio, cure rate and so on were all improved. The results of the qualitative interviews showed: the TB patients and the doubts among prisoners could be well gotten together and isolated to receive DOTS; doctors were able to receive trainings on TB treatment and take appointment with certificate. Conclusion According to the results of qualitative interviews, the published and the secondary documents, it could be seen that DOTS are well implemented with remarkable effects.
ObjectiveTo investigate the methodological and reporting quality of clinical trials involving Xiaoyao San for chronic fatigue syndrome. MethodsWe searched PubMed, CBM, CNKI, VIP and WanFang Data to identify randomized controlled trials (RCTs) about Xiaoyao San for chronic fatigue syndrome. The methodological and reporting quality of included RCTs was respectively evaluated according to the assessment tool of risk of bias of the Cochrane Handbook 5.1.0 and the CONSORT 2010 statement, combined with complementary assessment by the characteristic indicators of traditional Chinese medicine (TCM). The methodological and reporting quality of included case series study was respectively assessed by the methods recommended by the Britain's National Institute for Clinical Excellence (NICE) and the STROBE statement. ResultsA total of 27 clinical trials were included, involving 11 RCTs and 16 case series studies. According to the assessment tool of risk of bias of the Cochrane Handbook, 54.5% of the RCTs performed proper random method, 9.1% conducted allocation concealment and blinding, 72.7% selected intention-to-treat (ITT) analysis without the report of loss to follow-up, and no RCT existed selective reports. Corresponding to the characteristic indicators of TCM, 54.5% of the RCTs did not conduct TCM syndrome diagnosis, the curative effect standard of TCM syndrome was discrepant, and no RCT was multi-center study. The CONSORT 2010 statement indicated that no RCT explained sample size estimation, implementation details of randomization, flow diagram of participant, use of ITT and clinical trial registration. According to the items recommended by Britain's NICE, 6.25% of the case series studies were multi-center, 81.25% did not report clear inclusion and exclusion criteria, and no case series study performed continuous patient recruitment and stratification analysis of outcome. The STROBE statement indicated that no case series study reported research design, sample size, flow chart, bias, limitations and generalizability. ConclusionThe quality of clinical trials about Xiaoyao San for chronic fatigue syndrome is still low in methodological and reporting aspects. It is suggested that the future clinical trials should be conducted with references of CONSORT statement and STROBE statement, to propel the modernization and internationalization of TCM.
Critical flicker fusion frequency (CFF) is a dynamic visual function test that measures the minimum frequency at which a flicker source is perceived by the visual system as continuous light. The measurement method is convenient, the inspection time is short, and it can be effectively evaluated in the case of refractive interstitial opacity. Although CFF has many advantages, its application in the field of ophthalmology has not received sufficient attention. The pathway of CFF involves the pathway from the retina to the lateral geniculate body to the primary visual cortex, where the macrocellular pathway is sensitive to temporal resolution and responsible for transmitting rapidly changing information. Its measurements typically use red, green, or yellow light as a flashing light source to detect the functional integrity of the macular region. As a subjective test, the results of CFF can be affected by a variety of factors, such as drug use, fatigue, and luminous intensity. In order to improve the repeatability of the measurement, it is necessary to follow standardized measurement steps. CFF has important application value in the diagnosis of optic nerve diseases. It can assist in diagnosing the presence of optic neuropathy, evaluating the conduction function of the optic nerve, and monitoring the progression of the disease and the effect of treatment. As a convenient and efficient visual function evaluation tool, CFF has great potential in the diagnosis of optic nerve diseases and visual function monitoring. In view of its application prospects in the field of ophthalmology, this study calls for more attention and support from ophthalmologists, and carry out related basic and clinical research to further explore the application value of CFF in different disease conditions.
It has been absent from an accepted criteria for normalization and quality control of the thoracic surgery until now. The ideal assessing instrument which will be used to evaluate the technical skills and surgical procedures should present a few vital characterizations below: objectivity, speciality in the content, detailed structure, and quantifiability. Objective structured assessment of technical skills (OSATS) has developed as a reliable method of surgical skills measurement. This article focuses on the history of OSATS and its prospect in the thoracic surgery area by reviewing relevant literatures.
Objective To determine the influence of combinative assessment of transrectal ultrasound (TRUS) and serum amyloid A protein (SAA) on the assessment of preoperative staging selection of operative procedures in the middle and lower rectal cancer. Methods Prospectively enrolled 130 patients, who diagnosed definitely as middle and lower rectal cancer at West China Hospital of Sichuan University from June 2008 to February 2009 were randomly assigned into two groups with 65 participants, respectively. In one group named TRUS combined SAA group, both TRUS and SAA combinative assessment were made for the preoperative evaluation. In another group named TRUS group, only the preoperative TRUS was made. The preoperative staging and predicted operative procedures were compared with postoperative pathologic staging and practical operation program, respectively.Results Of 118 patients with rectal cancer were actually included into TRUS combined SAA group (n=59) and TRUS group (n=59). The baselines of characteristics of two groups were basically identical. For TRUS combined SAA group， the accuracies of preoperative T and N staging were 79.7% (47/59) and 77.8% (42/54) respectively; For TRUS group the corresponding rates were 86.4% (51/59) and 57.7% (30/52), respectively. There was no statistically significant difference of the accuracy of preoperative T staging （P=0.609） while preoperative N staging had statistical difference (P=0.027) between two groups. There was a statistically significant difference of the accuracy of prediction to operative procedures in two groups 〔96.6% (57/59) vs. 83.1% (49/59), P=0.015〕. The preoperative T staging was related to the selection of operative procedures (P=0.037) when analyzing the relationship between the operative procedures and the multiple clinicopathological factors in middle and lower rectal cancer. ConclusionCombinative assessment of TRUS and SAA could improve the accuracy of preoperative staging in middle and lower rectal cancer, thus provide higher predictive coincidence rate to operative procedures for surgeon.
Mitral valve regurgitation is one of the most common heart valve diseases, of which secondary mitral valve regurgitation (sMR) has large proportion and poor prognosis. For patients who still have symptoms after the guideline-directed management and therapy, the effects of surgery are controversial, and transcatheter therapy provides a new option. Transcatheter edge-to-edge repair has become one of the recommended therapies by the guidelines, meanwhile transcatheter mitral valve annuloplasty and transcatheter mitral valve replacement are developing. However, the etiological mechanism of sMR is complex and diverse. There is an interaction between cardiac function and structure and sMR in dynamic change. It brings challenges to the selection of indicators and evaluation timing. The complex anatomical structure also makes it more difficult to design instruments and select surgical methods. This paper reviews the challenges and progress of transcatheter therapy for sMR.
The study appeared the comparison between CONSORT and CENT, and promoted the combination with GRADE and N-of-1 trial. Our objective is to further develop the method of N-of-1 trial and to widely use it in clinical researches of some diseases.
Objective To primarily test the reliability and validity of the Kashin-Beck Disease (KBD) affected big joints function assessing system for adult Tibetans in Rangtang County. Method From June to July 2009, 142 KBD patients were investigated with the function assessing system in Rangtang County of Ngawa. Cronbach’s α coefficient was calculated to estimate internal consistency reliability. Pearson’s r for the correlation of the items with the total score of the scale was computed to test the internal validity. Principal component factor analysis with varimax rotation analysis was conducted to explore construct validity. Result Both the response and complete rates of the scale were 100%. The time for completing the scale was 7.8±3.4 minutes. Cronbach’s α was 0.857, which revealed satisfactory internal consistency reliability. Pearson correlation analysis revealed significant correlation between the scores of each item and the total score of the scale (Plt;0.05). Pearson’s r value of each item was more than 0.4, only except the items of “sitting with legs crossed” and “standing at attention”. The principal factor analysis extracted three latent factors explaining 68.1% of the variation together. The latent factors weights of the items were over 0.4 except the items of “standing at attention”, "taking food” and “wiping after defecation”. Conclusion The reliability and validity of KBD affected big joints function assessing system for adult Tibetans in Rangtang County was good in this primary test, the function assessing system has to be widely applied and further assessed among Tibetans suffered with KBD, in order to provide a standard evaluation criterion in KBD integrate control.
