Background Mortality and morbidity of acute myocardial infarction remains high. Intravenous magnesium started early after the onset of myocardial infarction is a promising adjunctive treatment that may limit infarct size, prevent serious arrhythmias, and reduce mortality. Several earlier trials and meta-analyses demonstrated a mortality rate reduction with magnesium treatment, but one mega trial found no benefit. Objective To examine the effect of intravenous magnesium versus control on early mortality and morbidity, stratified by time since onset of symptoms (lt;6 hours, 6+ hours), use of thrombolysis (used, not used), dose of magnesium used (lt;75 mmol, 75+ mmol). Search strategy We search the Cochrane controlled trial register (CCTR) of Cochrane Library, Medline and Embase. We also search Chinese Biomedical Disk (CBM disk) to identify the Chinese trials. Each database will be searched from its starting date to the first-half year of 2002. Selection criteria All randomized controlled trials that compared intravenous magnesium with placebo in the presence or absence of fibrolytic therapy in addition to routine treatment are eligible if they reported mortality and clinical events within 35 days of onset, regardless of language. Methods of review A data abstraction form will be specifically developed to extract information from the eligible articles. The quality assessment of RCT will be focused on method of treatment assignment, blinding of participants and investigators, control of selection bias after treatment assignment. The selection of studies, data extraction and assessment of methodological quality will be performed independently by two reviewers. Disagreements will be resolved through discussion, when necessary, in consultation with a third reviewer. Publication bias, heterogeneity and sensitivity analysis will be performed. The odds ratio (OR) will be used to pooling the effect if appropriate.
【Abstract】Objective To study the difference of telomerase activity in the common thyroid lesions . Methods The telomerase activity was detected in 19 patients with thyroid carcinomas, 15 samples adjacent to thyroid carcinomas，21 specimens of thyromas, 17 cases of nodular goiters and 13 pieces of normal thyroid tissues by telomeric repeat amplification protocol（TRAP). Results Eighteen of 19 samples of thyroid carcinoma, 1 of 15 samples adjacent to the cancer and 1 of 21 adenoma of the thyroid specimens showed positive telomerase activity, all 17 cases of nodular goiters and 18 samples of normal thyroid tissues exhibited negative telomerase activity, and the rate of positive telomerase activity of thyroid carcinomas was significantly higher than that of the other tissues (P＜0.0001). Conclusion The telomerase is an important qualitative marker of thyroid carcinoma and a useful index in differential diagnosis of thyroid lesions.
Precision medicine is a personalized medical system based on patients' individual biological information, clinical symptoms and signs, forming a new clinical research model and medical practice path. The basic idea of traditional Chinese medicine and the concept of precision medicine share many similarities. The basket trial developed for precision medicine is also suitable for clinical trials and evaluation of the efficacy of traditional Chinese medicine syndrome differentiation and treatment systems. Basket trials are used to evaluate the efficacy of a drug in the treatment of multiple diseases or disease subtypes. It has the advantages of sharing a master protocol, unifying management of subsidiary studies, simplifying the test implementation process, unifying statistical analysis, saving resources, reducing budgets and accelerating the drug evaluation progress. This is similar to the concept of using the "same treatment for different diseases" found in traditional Chinese medicine. This paper introduced the concept and method of basket trials and explored their application and advantages in clinical research into traditional Chinese medicine. This study is expected to provide references for the methodological innovation of clinical research into traditional Chinese medicine.
ObjectiveTo compare the clinical efficacy and complications of intra-arterial chemotherapy (IAC) and intravenous chemotherapy (IVC) for unilateral advanced retinoblastoma (RB). MethodsA retrospective clinical study. From January 2020 to January 2021, 40 patients (40 eyes) unilateral group cT2 RB patients diagnosed at Baoding Children’s Hospital and Beijing Children’s Hospital were recruited in this study. There were 22 males (22 eyes) and 18 females (18 eyes). All were monocular. All the patients were assigned to two groups according to different treatment modalities they received: IVC group and IAC group. There were 26 eyes and 14 eyes, respectively. When the tumor invades the optic nerve, choroid, sclera, anterior chamber and iris, enucleation was performed. The globe salvage rate, tumor extraocular metastasis rate, solid tumor control rate, treatment-related complications and pathological high-risk factors after enucleation were observed. The globe salvage rate and solid tumor control rate were compared between the groups by chi square test. ResultsThe globe salvage rate of IAC group and IVC group were 88.5% (23/26) and 50.0% (7/14), respectively. Solid tumor control of IAC group and IVC group were 84.6% (22/26) and 42.9% (6/14), respectively. There were statistically significant differences in globe salvage rate and solid tumor control between the two groups (χ2=7.18, 7.56; P＜0.05). Compared with IVC group, IAC group had less systemic complications, mild ocular and periocular side effects. Among 26 cases in IAC group and 14 cases in IVC group, 3 and 7 cases underwent enucleation respectively. The results of pathological examination showed that there were 2 cases and 3 cases with pathological high-risk factors in the two groups, respectively. During the follow-up period, 2 cases in IAC group had extraocular metastasis, there was no extraocular metastasis in IVC group. ConclusionCompared with IVC, IAC has the advantages of high tumor control rate, high globe salvage rate, less and mild complications, however, there is still tumor recurrence.
With the widespread promotion and application of the Enhanced Recovery After Surgery (ERAS) concept in the surgical fields, the implementation of the ERAS concept in the treatment of lower extremity deep venous thrombosis (DVT) was explored in the vascular surgery. The “Six-Step” comprehensive treatment protocol and the establishment of the ERAS system for lower extremity DVT developed by the Department of Vascular Surgery at the First Affiliated Hospital of Chongqing Medical University were elaborated. The protocol includes steps such as filter placement, thrombus clearance, relief of venous outflow obstruction, dissolution of residual thrombus, filter retrieval, and standardized post-discharge anticoagulation management, along with their respective advantages. Additionally, the training and dissemination efforts undertaken to promote the “Six-Step” comprehensive treatment protocol were described. A comparison was made between ERAS and traditional recovery surgery, highlighting the comprehensive clinical benefits of the former. The aim is to promote the standardized implementation of the ERAS system in lower extremity DVT treatment and to bring greater benefits to patients.
Background In the latter of 20th century, a global growth in allergic diseases has been witnessed, accompanying with spring-out of therapeutic drugs. However, trials did not clarify the comparative effectiveness and pharmaceutical economics of these agents. Severe adverse drug effects have been reported increasingly in the last few years. These made it difficult for clinical practice and selection of national essential drugs. Objective To assess astemizole, loratadine, cetirizine and tefenadine for allergic rhinitis (AR) and urticaria in terms of effectiveness, heart-related drug adverse effects and pharmaceutical economics. Search strategy Cochrane Library, Medline, Embase and Chinese Biomedical Database will be searched. Additional database should be searched for safety and economic studies. Selection Criteria The publication languages are restrained to English and Chinese. 1) Effectiveness: high-quality randomized controlled trials (RCTs) and systematic Reviews (SRs)/ meta-analysis for AR and uritcaria are included, with comparisons restrained to among these four drugs; 2) Safety: a hierarchy of evidences of these four drugs for allergic diseases are included. 3) Economical evaluation: cost-effectiveness and cost-utility assessment of these four drugs for AR and urticaria should be included. Methods of review data extraction sheet and quality appraisal table are separately designed. QUOROM STATEMENT and Jadad Scale are applied, respectively, to SRs and RCTs. Two reviewers independently select the studies, appraise the quality and extract the data. Any disagreement is solved by discussion. Data analysis Fixed effect model is first applied. Sensitivity analysis is employed to study the heterogeneity between trials. Randomized effect model is alternatively used when compromised.

In order to optimize the patient visit flow, the Day Surgery Center, Medical Affairs Department, Outpatient Department, Surgical Anesthesia Center and some relevant departments of West China Hospital of Sichuan University implemente whole process management of patients undergoing general outpatient surgery. Based on the practice of general outpatient surgery, West China Hospital of Sichuan University summarized and drafted the management protocol of general outpatient surgery from the aspects of organizational structure, management system and emergency plan, in order to provide a reference for the standardized development of general outpatient surgery in China.
Objective To investigate the consistency of regions of interest (ROI) volume among different radiological treatment planning systems (TPS) for the same group of patient data, and analyze the tendency and degree of differences caused by data transfer. Methods Between October 2010 and December 2013, the data of 10 nasopharyngeal carcinoma patients treated in West China Hospital were transferred from Monaco TPS into various other treatment planning systems. Based on different ROI volumes, they were divided into 8 groups. We counted the volume differences between these TPS and Monaco TPS, and carried out the statistical analysis. Results For small ROI volume, the calculated difference reached up to 65% in our study. As a general trend, differences became less and less with the increasing of volumes. But for single ROI, the volume difference was likely to vary randomly. The percentage of ROI volumes which were smaller than that of Monaco TPS was 70% for Raystation TPS, 38.75% for Pinnacle TPS, 88.75% for Eclipse TPS, 97.5% for Masterplan TPS, and 83.13% for iPlan TPS. Conclusions ROI volume differences exist generally among different treatment planning systems when ROIs are transferred among them by DICOM protocol. The volume variations may be affected by multiple factors. The volume consistency should be evaluated before any direct comparison of dose volu me histogram parameters which are done between different systems.
