Objective To study the clinical characteristics of mulifocal motor neuropathy. Methods Patients records in China Biological Medicine Database (CBM-disc 1980-2005)and WanFang Database were searched. Demographic data, clinical manifestations, electrophysiology, and laboratory findings on multifocal motor neuropathy were analyzed. Results Of the total 80 patients, 61 cases were males, and 19 were females. A single limb weakness began in all the patients. Weakness was usually accentuated distally(95.3%), accompanied by muscle amyotrophy(76.3%) and fasciculation(46.3%). Reflexes were reduced (96.4%). Sensory impairment and cranial involvement were rare. 92.1% of the patients showed conduction block of motor nerve. Results Of the total 80 patients, 61 cases were males, and 19 were females.

MMN should be differentiated from motor neuron disease and chronic inflammatory demyelinating polyneuropathy.
ObjectiveTo assess the methodological quality of guidelines for bronchoscopic alveolar lavage. MethodsCNKI, VIP, WanFang Data, CBM, Web of Science, PubMed, EMbase databases and medlive.cn, the National Guideline Clearinghouse (NGC), the National Guideline International Network (GIN), the Scottish Intercollegiate Guidelines Network (SIGN), the National Institute for Clinical Excellence (NICE), and the World Health Organization (WHO) websites were electronically searched to collect guidelines of bronchoscopic alveolar lavage from inception to December 2020. Two reviewers independently screened literature, extracted data, and assessed the methodological quality of the guidelines by using AGREE Ⅱ tool. ResultsA total of 19 guidelines were included, with 5 from China, 5 from the USA, 3 from Europe, 2 from the UK, 1 from Australia, 1 from Israel, 1 from Spain, and 1 from India. The average standard score rates of the 19 guidelines in the six fields were 50.73% for scope and purpose, 20.02% for participants, 15.13% for formulation rigor, 36.40% for clarity of presentation, 3.51% for applicability, and 22.37% for editorial independence.ConclusionsThe quality of bronchoalveolar lavage guidelines remains relatively low.
ObjectivesTo evaluate the methodological quality of guidelines for pharmacological intervention of migraine in adults, to compare and analyze the differences in first-line drug recommendations in different regions and quality levels, so as to explore the evidence of drug recommendations, and provide a basis for clinical decision-making.MethodsPubMed, The Cochrane Library, EMbase, SinoMed, CNKI, VIP, and WanFang Data databases, Up To Date, as well as the related books, Yimaitong, Guideline Central, Guidelines International Network (GIN) and National Institute for Health and Clinical Excellence (NICE) were systematically searched to collect pharmacological intervention guidelines of migraine in adults from inception to January 12th, 2020. The methodological quality of the guidelines was evaluated by Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ).ResultsA total of 25 guidelines were included (including 22 evidence-based guidelines), covering 10 countries on 4 continents and World Health Organization (WHO) with a time span of 1997 to 2019. According to AGREE Ⅱ, 5 were A-level guidelines, 18 were B-level guidelines, and 2 were C-level guidelines. Scope and purpose, rigour of development, clarity of presentations and editorial independence obtained high average scores (more than 60%) among all 25 guidelines. The average scores of guidelines in different domains of AGREE Ⅱ varied with regions and countries. Triptans and NSAIDs were the most frequently recommended as first-line drugs for the acute management; beta-blockers and antiepileptic drugs were recommended for the first-line prevention drugs of migraine in adults. There were 2 guidelines that recommended complementary treatments, one recommended traditional Chinese medicine and another recommended herbal butterbur.ConclusionsThe methodological quality of the pharmacological intervention guidelines of migraine in adults is suboptimal among different regions or countries. The quality of evidence-based guidelines is superior to that established by consensus. The consistency of first-line drug recommendations is strong, but there are still regional differences. The therapeutic effect of traditional Chinese medicine requires further verification.
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.
Objective To investigate the correlation between nutrition related blood biochemical indexes levels and Patient-Generated Subjective Global Assessment (PG-SGA) in preoperative nutritional assessment of patients with gastric cancer. Methods One hundred and seventeen gastric cancer patients who underwent surgery were enrolled in this study by the Department of Gastrointestinal Surgery of West China Hospital. Nutritional status of each patient was evaluated by PG-SGA, in the meantime, nutrition related blood biochemical indexes levels such as transferrin (TRF), prealbumin (PA), albumin (Alb), and hemoglobin (HGB) were measured by analysis of fasting venous blood, then take correlation analysis on the result. Results Eighty cases (68.4%) were in malnutrition (PG-SGA score≥4). The TRF, PA, Alb, and HGB in malnutrition patients were lower than those in non-malnutrition patients (PG-SGA score<4, n=37, P<0.05). The TRF, PA, Alb, and HGB levels of gastric cancer patients had significant negtive correlation with PG-SGA score, the correlation coefficients was –0.629, –0.545, –0.418, and –0.235, respectively (P<0.05). When the PG-SGA score was greater than or equal to 4 points, the optimum cutoff value for TRF, PA, Alb, and HGB was 2.31 g/L, 190.50 mg/L, 38.65 g/L, and 100.50 g/L, respectively (P<0.05). Conclusions The incidence of malnutrition is high in gastric cancer patients preoperatively. The TRF, PA, Alb, and HGB are significantly decreased in the patients with malnutrition, and these indicators has significant negtive correlation with PG-SGA score. The current study indicated that a gastric cancer patient might be in malnutrition when the biochemical levels are less than or equal to TRF 2.31 g/L, PA 190.50 mg/L, Alb 38.65 g/L, HGB 100.50 g/L, and sufficient attention should be paid when any of these occasions appear clinically. The combination of PG-SGA score and nutrition related blood biochemical indexes levels could provide a more accurate assessment of preoperative nutritional status, and the evidence of nutritional intervention for patients with gastric cancer.
Breast cancer, the most common malignancy in the world, also causes the most death cases of women among malignancies. Breast cancer risk reduction guidelines (version 2023) was updated by National Comprehensive Cancer Network (NCCN). Based on high-level evidences from evidence-based medicine and the latest research progress, the guidelines provided standardized guidance for breast cancer risk assessment and risk reduction strategies for individuals without a history of invasive breast cancer or ductal carcinoma in situ, which has attracted widespread attention from clinicians worldwide. Breast cancer is also the most common malignancy in Chinese women, and the number of newly diagnosed breast cancer cases each year in China ranks first in the world due to the large population, so the breast cancer prevention has become a major public health challenge in China. Aimed to provide reference for breast cancer prevention in China, this article interpreted the guidelines (the new version) based on the characteristics of breast structure in Asian women and the epidemiological characteristics of breast cancer in China.
ObjectiveTo review the advances in the diagnosis and treatment of obstetric brachial plexus palsy (OBPP). MethodsThe incidence, risk factors, classification, and imaging tests of OBPP and indication, technique, and results of surgery were reviewed and summarized. ResultsThe incidence of OBPP is not declining in recent years. Birth weight of ≥4 kg, forceps delivery, and prepregnancy body mass index of ≥21 are considered to be major risk factors, and caesarean section delivery seems to be a protective factor. Neurophysiological investigations can be applied to qualitative diagnosis of OBPP, but can not to quantitative one. Sensitivity and specificity of both CT and MRI myelography are about 0.7 and 0.97, respectively. Narakas classification is widely used:C5, 6 injury as type I, C5-7 injury as type Ⅱ, C5-T1 injury as type Ⅲ, C5-T1 injury with Horner's syndrome as type IV. It is generally considered that the brachial plexus exploration should be undertaken for infants without spontaneous recovery of elbow flexion by a maximum of 3 months old; and 10% to 30% of patients may need nerve reconstruction surgery. It is advocated that traumatic neuroma of the upper trunk should be resected with nerve reconstruction. The final evaluation for surgical results should be at minimal 4 years for upper roots and 8 years for total roots. Scales of Mallet, Gilbert, and Raimondi are mostly used for assessing shoulder function, elbow function, and hand function. ConclusionBrachial plexus exploration should be undertaken for infants without flexion of elbow at the age of 3 months. Traumatic neuroma (even neuroma-in-continuity) resection followed by microsurgical reconstruction of the brachial plexus is favored.
ObjectivesTo explore classification management method of evidence-based evidence for medical consumables based on cost multiplication and to conduct empirical test.MethodsFour quadrants was used to explore the classification management of consumables evidence.Results95.22% of the “recommended” items in the consumables department were “recommended” by the group. 100% of group “recommended” items passed the committee resolution. Advice of consumables department and group was highly relevant with decision of commission.ConclusionsOne-dimensional recommendations allow the decision-making of group and committee to be more convenient. Cost calculation is based on all consumables required for medical treatment, which is similar to reality. The classification threshold requires further optimization, and the classification basis requires continual adjustment under different conditions of hospital. The evidence-based evidence evaluation method for medical consumables based on incremental cost ratio is a simple and rapid hospital health technology assessment method suitable for China’s national conditions.
ObjectiveTo explore the possible association between early injury assessment indexes and the length of stay (LOS) in first-line hospitals, in order to help the hospitals take advantage of resource effectively and transfer victims reasonably during earthquakes. MethodWe retrospectively analyzed the medical information of 3 576 traumatic patients injured in the Wenchuan Earthquake who were transferred to 242 first-line medical institutes between 14:28, May 12th and 14:30, May 19th in 2008. Three kinds of 15 variables were extracted for the analysis, including gender, age, heart or lung disease, pre-hospital time, head injury, trunk injury, open injury, crush injury, asphyxia, body temperature, heart rate, respiration, systolic blood pressure, diastolic blood pressure, and Glasgow coma score. Multiple stepwise linear regression analysis was performed to identify the factors associated with LOS. ResultsThe multiple linear regression analysis showed that age as well as other six factors affected LOS significantly (P<0.05). The partial regression coefficients of age, pre-hospital time, head injury, trunk injury, crush injury, complication of cardiac or pulmonary disease, and Glasgow coma score were -0.062, 0.157, 3.703, 4.111, 12.602, 14.762 and -1.312, respectively. ConclusionsEarthquake trauma patients with older age, long pre-hospital time, head injury, trunk injury, heart or lung disease, crush injury, and lower Glasgow coma score are at increased risk for extended LOS.
