Abstract
To provide directional suggestions for the establishment of international clinical practice guidelines for acupuncture and moxibustion by investigating the current situation of clinical practice guidelines for acupuncture and moxibustion at home and abroad. The clinical practice guidelines were obtained by questionnaire survey, database retrieval and experts consulting. The guidelines were read carefully, and the content was analyzed. A total of 27 acupuncture-moxibustion clinical practice guidelines were retrieved, of which most of the guidelines came from China. The definition and scope of "acupuncture and moxibustion "vary according to different guidelines; and the focus of the content and the method of establishing the guidelines are quite different, so it is very necessary to unify the formulation methods of acupuncture-moxibustion clinical practice guidelines. Chinese clinical practice guidelines for acupuncture and moxibustion were characterized by taking the ancient literature as the evidence. Excavating the value of ancient literature and clinical experience of acupuncture-moxibustion experts are the key points and difficulties in the developing of clinical practice guidelines of acupuncture and moxibustion in the future.

Abstract
To sort out the existing problems within the published 35 evidence-based acupuncture-moxibustion clinical practice guidelines (group standards) in Chinese: the development methods and the development process are not clear and strict enough; the evidence evaluation system fails to fully reflect the characteristics of acupuncture and moxibustion. Therefore, Norms for Formulation and Evaluation of the Guidelines on Clinical Practice of Acupuncture-Moxibustion, should require the guideline developers to consider the characteristics of acupuncture discipline, evaluate modern literature evidence comprehensively, and integrate ancient literature and medical experts' experience, to form proper recommendations for clinical practice. Specific requirements should be made simultaneously in the development process to make it clearer and stricter.

Abstract
The electronic questionnaire was adopted to survey the international demand on Technical Specification of Acupuncture-Moxibustion: General Rules of Drafting (General Rules for short) to explore the potential problems during the application and provide the evidence for the development of international standard of General Rules. A total of 102 valid questionnaires were collected from 18 countries and regions. The priority of the demand for international standard on the technical specification of acupuncture-moxibustion is filiform needle, moxibustion, electroacupuncture, cupping, auricular acupuncture, scalp acupuncture and scraping. One hundred experts (98.04%) at home and abroad believe the necessity of the international standard development of General Rules. The awareness rate of the existing national standard of General Rules is 71.57% and the foreign experts think that its expression may be "unclear" and the domestic experts think it may be "lack of practicability". The domestic experts hope to highlight the commonness in the scope of the international standard of General Rules and the foreign experts hope to retain more individuality. Regarding the specific questions during the technique manipulations of acupuncture-moxibustion, there are the big differences in "relevant terminology" "preoperative preparation" and "adverse reaction and contraindications" at home and abroad. In order to improve the international compatibility and applicability, it is necessary to give full consideration to the needs of different countries in the development of international standard of General Rules and balance as far as possible between refining "common problems" and satisfying "individual needs".

Abstract
Objective: To provide a portable electroencephalograph that can facilitate long-term monitoring of epilepsy patients outside the hospital, and establish a medical platform for epilepsy data monitoring and treatment. Methods: From June 2018 to October 2019, twenty-nine patients from Huashan Hospital (superior hospital) and Jing'an District Central Hospital (subordinate hospital) of Fudan University were enrolled in the study. Among them, twenty-eight cases were diagnosed with epilepsy and 1 case was epileptic seizure. Electroencephalogram (EEG) was collected by portable electroencephalograph once a week and followed up for three months. The seizure frequency, seizure form, medication type, EEG lead number and positive rate were recorded. Patients' medical records and EEG data were uploaded to the cloud database to build a medical alliance platform. Doctors of different levels of hospitals couldobtain diagnosis and achieve resource sharing based on the platform. The data was statistically analyzed using SPSS 18.0. Results: The EEG data collected by the portable electroencephalograph hadfewer artifacts, complete sleep cycle, and could record the interictaldischarges. Twenty-nine patientsunderwent a total of 148 EEG monitoring during the three-month follow-up. Eighty-five cases of epileptic discharges were detected, and the EEG positive rate was 57.4%. The positive rate of EEG in patients with generalized seizures (84.9%) was higher than that in patients with focal seizures (42.1%) (P<0.01); the positive rate of EEG in patients with 2-3 antiepileptic drugs and patients with frequent seizures within three months were also higher (P<0.05). Doctors in the superior hospital in the platform make diagnosis and treatment suggestions according to the above data. Elevenseizure-free patients and four patients with fewer seizures and discharges were diverted to the community hospital for follow-up. Fourteen patients with poor seizure control and/or continuous epileptic discharges were diverted to the superior hospitalto adjust the medication. Doctors of subordinate hospital acquired the diagnosis and treatment suggestions through the platform, and then strengthened the daily care and follow-up. Conclusion: Combined with a portable electroencephalograph, the current study establishs a medical platform for patients with epilepsy to achieve long-term monitoring and rational use of medical resources.

Abstract
Through sorting out the development of meridian points and the standardization of extraordinary points in dynasties, two objectives are discovered in the standardization of extraordinary points starting from the Tang Dynasty. The points with extraordinary effect are selected points and transferred to meridian points and the commonly-used key points are selected and developed to be standardized acupoints. Hence, 3 approaches are summarized. Approach No.1: a large number of "meridian-outside" points that are the potential supplementation but not included yet in meridian points are supplemented to meridian points. Approach No.2: based on the specified requirement, the key points are selected from the acupoints with determined locations and names, which is developed to be the standard of acupoints. Approach No.3: the acupoints with extraordinary effect are selected from the "meridian-outside" points and these points are collected for the formulation of the standard of extraordinary points. The latter two approaches provide for the development direction of teaching and standardization in the future.

Abstract
Through an analysis of the historical development of the concept of extra ordinary point, it is found that the terms of "Qi point" "extra ordinary point" "Loujing point" "extra meridian point" and "Bie point" used in the ancient medical books in the Yuan, Ming, and Qing Dynasties actually expressed two different concepts of "extra ordinary points with the magical effects" and "extra points other than the meridian points". The standardized term for the former concept should be "extra ordinary point" (Qi point for short), and the standardized term for the latter concept should be "extra meridian point", which is also called "Loujing point" and "Bie point". Since these two different concepts are not clarified in modern acupuncture textbooks, especially the misreading of "Jing Wai", no consensus has been reached on the definition of "extra ordinary point" and "extra meridian point", and the standardized terms have not been decided, which changed from "extra ordinary point" to "Qi point" and "extra point" and recently returned to "extra ordinary point". These confusions in textbooks have a direct impact on the determination of the related acupuncture terms used in national and international standards.

Abstract
Flax seed meal (FSM) is rich in various nutrients, especially CP and energy, and can be used as animal protein feed. In animal husbandry production, it is a long-term goal to replace soybean meal (SBM) in animal feed with other plant protein feed. However, studies on the effects of replacing SBM with FSM in fattening sheep are limited. The aim of this experiment was to study the effects of replacing a portion of SBM with FSM on nutrient digestibility, rumen microbial protein synthesis and growth performance in sheep. Thirty-six Dorper × Small Thin-Tailed crossbred rams (BW = 40.4 ± 1.73 kg, mean ± SD) were randomly assigned into four groups. The dietary treatments (forage/concentrate, 45 : 55) were isocaloric according to the nutrient requirements of rams. Soybean meal was replaced with FSM at different levels (DM basis): (1) 18% SBM (18SBM), (2) 12% SBM and 6% FSM (6FSM), (3) 6% SBM and 12% FSM (12FSM) and (4) 18% FSM (18FSM). The rams were fed in individual pens for 60 days, with the first 10 days for adaptation to diets, and then the digestibility of nutrients was determined. There was no significant difference in DM intake, but quadratic (P < 0.001) effects on the average daily gain and feed efficiency were detected, with the highest values in the 6FSM and 12FSM groups. For DM and NDF digestibility, quadratic effects were observed with the higher values in the 6FSM and 12FSM groups, but the digestibility of CP linearly decreased with the increase in FSM in the diet (P = 0.043). There was a quadratic (P < 0.001) effect of FSM inclusion rate on the estimated microbial CP yield. However, the values of intestinally absorbable dietary protein decreased linearly (P < 0.001). For the supply of metabolisable protein, both the linear (P = 0.001) and quadratic (P = 0.044) effects were observed with the lowest value in the 18FSM group. Overall, the results indicated that SBM can be effectively replaced by FSM in the diets of fattening sheep and the optimal proportion was 12.0% under the conditions of this experiment.

Abstract
With the implementation of ultra-low-emission transformation in coal-fired power plants and other related industries in China, the concentrations of filterable particulate matter (FPM) and gaseous pollutants in exhaust gas from stationary sources have reduced significantly, while the emission of condensable particulate matter (CPM) remains a concern. In this study, the monitoring methods of FPM and CPM at a relatively low FPM concentration in exhaust gas from stationary sources in China and abroad were comprehensively analyzed. On the basis of existing research and experimental exploration, the monitoring methods of FPM and CPM were further studied. A direct condensation sampling and monitoring method for total particulate matter (TPM) in ultra-low-emission and high-humidity exhaust gas from stationary sources, which is suitable for the actual situation in China, was developed and established before being used to measure TPM in exhaust gas from a gas power plant in Beijing. The results showed that the emission concentration of TPM in the exhaust gas from the gas power plant was between 1.98 mg·m-3 and 3.77 mg·m-3 (average of 2.81 mg·m-3), whereas the average emission concentration of FPM was only 0.10 mg·m-3. The emission type of particulate matter in exhaust gas from the gas power plant was mainly CPM, which accounted for 93.8% to 99.2% of the TPM (average of 97.0%). The proportion of FPM to TPM ranged from 0.7% to 6.2% (average of 3.0%). The emission concentration of filterable CPM was slightly higher than that of FPM.

Abstract
OBJECTIVE The aim of this study was to evaluate the clinical results of a Bi-needle technique and conventional transforaminal endoscopic spine system (TESSYS) technique for percutaneous endoscopic lumbar discectomy (PELD) in treating patients with intervertebral disc calcification (IDC). BACKGROUND PELD has gained acceptance for treating patients with IDC. The Bi-needle technique was designed to improve the efficiency and safety of PELD. METHOD Bi-needle and TESSYS group within each cohort were balanced using 1:1 propensity score matching. Finally, 32 patients with IDC treated by Bi-needle technique from December 2015 to September 2017 were enrolled and 25 patients treated by TESSYS technique from the same spine surgery center between January 2013 and October 2017 were enrolled as controls. RESULTS Propensity score matching generated 22 Bi-needle and 22 TESSYS patients. There were no significant differences in visual analog scale and lumbar Japanese Orthopaedic Association scores between Bi-needle and TESSYS group. Operative time and rate of complications in the Bi-needle was significantly better than the TESSYS group (p < 0.01). CONCLUSIONS Both surgical methods achieved good clinical outcomes. However, compared with the TESSSY technique, operative time of the Bi-needle technique is shorter, and rate of complications is lower.

Abstract
PURPOSE The aim of this study was to investigate the effect of lumbar spine selective nerve root block (SNRB) experience on the learning efficiency of percutaneous endoscopic lumbar discectomy (PELD) for junior trainees. METHODS A total of 480 patients undergoing single-level PELD performed by eight junior trainees were included. The trainees were divided into two groups based on whether they had previous SNRB experience (group A, yes; group B, no). Surgical proficiency was defined as total operation time less than 65 minutes and cumulative radiation exposure time no more than 40 seconds. The learning curve was analyzed by cumulative summation (CUSUM) test. Clinical evaluations included Macnab classification, visual analog scale (VAS)-low back score, VAS-leg score, and Oswestry Disability Index (ODI). Follow-up information at 12 months was also obtained. RESULTS Integral number of cases before achieving an acceptable surgical level in group A (47.75 ± 2.50 cases) was significantly smaller than that in group B (56.50 ± 1.29 cases, p < 0.05), along with less accumulated failure (18.75 ± 0.96 cases vs. 25.50 ± 1.75 cases, p < 0.05). The two groups were comparable in clinical outcomes. Forty-seven cases of complications were observed, with 17 in group A and 30 in group B (p < 0.05). CONCLUSION Previous experience of SNRB improved the performance of PELD with shorter operation time and less radiation exposure. SNRB practice may reduce the complication rate without a significant effect on the recurrence of symptoms and reoperation.

Abstract
OBJECTIVE To analyze the performance of a liver graft sonographic grading system and point shear wave elastography (PSWE) in predicting early allograft dysfunction (EAD) after liver transplantation (LT). METHODS Successive brain-dead donors and liver recipients in our hospital from March 2017 to May 2018 were retrospectively recruited. All donors underwent PSWE examination, abdominal ultrasonography, and sonographic grading (grade 0 to grade 5). Donors with ≥ 10 valid PSWE examinations and a failure rate of < 60% were included. For all recipients, abdominal ultrasonography and blood tests for biologic parameters were performed preoperatively and daily postoperatively to screen for EAD. The recipients and their grafts were classified into EAD and non-EAD groups. Statistical analyses were performed to analyze the correlations among liver stiffness (LS), liver graft sonographic grading, and EAD. RESULTS Thirty-two donors and 32 corresponding liver recipients were enrolled (15 cases in the EAD group; 17 in the non-EAD group). There were no grade 0, 1, or 2 cases in the two groups. For prediction of EAD in recipients after LT, the AUC for PSWE was 0.929 and the AUC for combination of PSWE and sonographic grading system was 0.935. CONCLUSIONS Combination of PSWE and sonographic grading system can predict postoperative EAD in LT recipients with high sensitivity. Abnormal results may suggest a need for liver biopsy preoperatively, thus avoiding unnecessary surgical preparation for liver procurement. KEY POINTS • Combination of PSWE with new sonographic grading system is useful for preoperative evaluation of liver grafts from brain-dead donors. • EAD is as a criterion for evaluating the diagnostic value of PSWE and sonographic grading system. • Combination of PSWE and sonographic grading system can predict postoperative EAD in LT recipients with high sensitivity.

Abstract
STUDY DESIGN A retrospective study. OBJECTIVE To assess the long-term results of zero-profile spacer for 3-level anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND DATA Although widely used, there are still controversies about the long-term results of zero-profile spacer, especially in multilevel cases. METHODS Cases received 3-level ACDF for cervical spondylotic myelopathy (CSM) using either zero-profile spacer (n = 27) (ZP Group), or plate and cages (n = 34) (PC Group), and with 5-year follow-up were reviewed. Neurological function and life quality were assessed by modified Japanese Orthopaedic Association (mJOA) score, Neck Disability Index (NDI), and Short-Form 36 (SF-36) score. Disc height, cervical lordosis, fusion rate, and surgical complications were observed. RESULTS Neurological recovery and life quality improvement were similar in both groups. Disc height and cervical lordosis (C2-7 Cobb angle) were well restored after operations, but lost in both groups during follow-up. Loss of correction (LOC) in disc height was larger in ZP Group (11.38% vs 5.71%, P < 0.05) at 5-year follow-up. LOC of cervical lordosis in ZP group constantly grew from 11.28% to 48.13% during 5-year follow-up, significantly higher than that in the PC group (from 7.43% to 14.01%) (P < 0.05). The rate of postoperative dysphagia was no statistical difference between the two groups, and symptoms were all disappeared within 1 year. There were 10 levels of adjacent segment degeneration (1 in ZP Group, and 10 in PC Group, P = 0.02). Cage subsidence (11 of 81 levels, 13.58%) and screw migration (2 of 81 levels, 2.47%) were only observed in the ZP Group. The migrated screws in one case were surgically removed. Fusion was achieved in all cases. CONCLUSIONS In long-term follow-up of 3-level ACDF for CSM, zero-profile spacer has the similar clinical results, but loss of correction of disc height and cervical alignment were significantly higher, compared with anterior plate and cages. LEVEL OF EVIDENCE 3.

BACKGROUND Indications and clinical outcomes of percutaneous endoscopic thoracic discectomy(PETD) in treating thoracic disc herniation is rarely reported and still controversial. We reported an unsatisfied recovery of thoracic disc herniation with PETD, treated by a second posterior thoracic laminectomy and Ponte osteotomy. CASE DESCRIPTION A male presented with lower extremity weakness and stagger caused by T3/4 intervertebral disc herniation. The upper thoracic curve was in excessive kyphosis with T2-5 Cobb angle of 34.3 degrees. The preoperative ODI score was 34 and Roelzs's JOA score was 14. Percutaneous transforaminal endoscopic thoracic discectomy (PETD) from a posterior lateral approach was performed. At five-month follow-up, his thoracic back pain and staggering gait did not improve. The postoperative T2-5 Cobb angle was 32.1 degrees, the ODI score was 24 and Roelzs's JOA score was 14. A second posterior thoracic decompression this time with fixation was performed, but no disc herniation was detected. A Ponte osteotomy was performed to correct the kyphosis. One month after the second surgery, muscle strength of the lower limbs was improving with the T2-5 Cobb angle decreased to 19.4 degrees, the ODI score decreased to 10 and Roelzs's JOA score increase to 16. Six month later, the ODI score decreased to 0 and Roelzs's JOA score improved to 18. In review of the literature, PETD doesn't guarantee the patient a satisfactory neurological recovery for kyphotic thoracic disc herniation. Posterior decompression with Ponte osteotomy may be beneficial to release the tension and decompression of the spinal cord tension. CONCLUSIONS Thoracic disc herniation with kyphosis angle >20 degrees (T2-5), percutaneous endoscopic thoracic discectomy is not likely to get good neurologic results. Posterior laminectomy with ponte osteotomy might be beneficial for these patients to induce dorsal drifting of the spinal cord from anterior herniation.

[PMID: 31865087 DOI: 10.1016/j.scitotenv.2019.134670] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2019] [Revised: 09/23/2019] [Accepted: 09/25/2019] [Indexed: 06/10/2023]
Abstract
By differentiating intermediate trade from final trade, this paper combines typical statistics for the world economy in 2012 to explore the transfer of embodied carbon emissions via the global supply chain and the related trade imbalance. The emission transfer embodied in interregional trade is in magnitude around 40% of global direct carbon emissions. The global intermediate trade volume of embodied carbon emissions is estimated to be 2.3 times as much as the final trade volume. While Mainland China obtains a considerable economic trade surplus, its carbon trade deficit is about twice the carbon trade surplus of the United States. Mainland China's final trade deficit is around 1.2 times as much as its intermediate trade deficit of embodied carbon emissions. EU27, the United States, ASEAN and Japan serve as the major contributors to China's intermediate and final trade deficits. For the United States, its intermediate carbon trade surplus is almost equal to its final trade surplus. The United States gains a carbon surplus with most of its trading partners in both intermediate and final trades. A future scenario analysis in terms of carbon emission projection is conducted. While the direct and embodied carbon emissions of the United States and Japan are estimated to change slightly from 2012 to 2040, India's carbon emissions are projected to experience a twofold increase during the period. In the long term, though with ups and downs, the economic globalization will be inevitably moving forward, leading to a highly sliced-up global supply chain and increasingly delicate regional specialization as well as frequent intermediate trade between regions. It is suggested that nations and regions should follow this trend and adapt themselves to the global value chain by carefully assessing their roles in intermediate and final trades in terms of both currency and embodied carbon emissions.

Abstract
OBJECTIVE To carry out the methodological quality evaluation and content analysis of the evidence-based clinical practice guidelines for acupuncture-moxibustion in China, and to provide reference for the development and updating of future guidelines. METHODS With Appraisal of Guidelines for Research and EvaluationⅡ(AGREEⅡ), 20 evidence-based clinical practice guidelines for acupuncture and moxibustion in China were evaluated from six aspects: scope and purpose, stakeholder involvement, rigour of development, clarity of presentation, applicability and editorial independence. In addition, the contents of 20 guidelines were systematically analyzed, and the characteristics of guidelines were summarized from the aspects of disease selection, operation technology type and safety. RESULTS The scores of six domains were scope and purpose (91.1%), stakeholder involvement (68.5%), rigour of development (68.6%), clarity of presentation (90.3%), applicability (34.5%) and editorial independence (16.7%). The recommendations of the 20 acupuncture guidelines covered common clinical problems such as diagnosis, treatment and precautions, which were in line with the clinical characteristics of acupuncture and moxibustion in terms of content structure. CONCLUSION The methodology of the evidence-based clinical practice guidelines for acupuncture and moxibustion in China conformed to the requirements of AGREEⅡ on the quality evaluation, and the overall quality was moderate, but the aspects of applicability and editorial independence were still needed to be improved. The contents of recommendations in 20 guidelines were specific and clear, in line with the characteristics of acupuncture and moxibustion, presenting clinical reference value. In the future, in the process of guideline development, the method of developing acupuncture and moxibustion guidelines should be constantly improved to improve the quality of the guidelines; in the meantime, more attention should be paid to the generalization and clinical applicability evaluation.

Abstract
Background: We know of five cases of cervical nerve root variants that have been reported, all of which were found during posterior cervical surgery. We reported two cases of cervical nerve root variants. One had two anomalous branches of the C7 root, is the other had a C5, C6 nerve root communication branch. Case description: A 62-year-old female presented with neck and right upper extremity pain, accompanied by hypaesthesia in her right forearm for 4 months. Preoperative X-ray film, magnetic resonance imaging (MRI) and computed tomography (CT) scan demonstrated C6-7 uncovertebral joint hyperplasia and foraminal stenosis. She underwent posterior cervical endoscopic foraminoplasty. The right C7 nerve root was observed to have two anomalous branches originated from a proximal trunk. After the surgery, the symptoms resolved. A 54-year-old female presented with radiating pain and numbness in her right arm and hand for 4 months. Preoperative MRI showed a C5/6 intervertebral disc herniation. She had hypaesthesia in radial side of her right arm and 1st-3rd fingers. Posterior cervical endoscopic foraminalplasty was performed for the patient. After decompression of the bony wall of the posterior nerve root canal, a 2-mm thick communicating nerve was observed emerging from the dura with the C6 nerve root and exiting to the caudal level. After the surgery, the symptoms resolved immediately. Conclusions: Cervical nerve root variant may be more apparent on edoscopic approaches to the cervical foraminae than at open surgery.

Abstract
The detection of internal damage characteristics of concrete is an important aspect of damage evolution mechanism in concrete meso-structure. In this paper, the improved Faster R-CNN is used to detect the porosity and cracks in concrete CT images. Based on the Faster R-CNN, ResNet-101 and ResNet-50 are used as the main framework. Feature pyramid network (FPN) and ROI Align are introduced to improve the performance of the model. FPN can generate high quality feature maps. ROI Align solves the region mismatch caused by the quantization operation. Experiments show that the detection accuracy of ResNet-101[Formula: see text]+[Formula: see text]FPN[Formula: see text]+[Formula: see text]ROI Align reaches 87.08%, which is 4.74 higher than that of ResNet-101. The detection accuracy of ResNet-50 [Formula: see text]+[Formula: see text] FPN [Formula: see text]+[Formula: see text] ROI Align reached 81.36%, which is 3.12% points higher than ResNet-50. These two improved algorithms are slower than the original algorithm for the detection time of a single picture. An effective method is provided to analyze concrete meso-damage evolution through the research.

Abstract
BACKGROUND Circulating exosomal microRNAs modulate not only cancer cell metabolism but also the immune response, and therefore plasma exosomal microRNAs might have the potential to be the biomarkers for a number of immune disorders. OBJECTIVE This study was conducted to identify the common mechanisms among psoriatic arthritis (PsA), psoriasis vulgaris (PV), rheumatoid arthritis (RA), and gouty arthritis (GA). The common expressed plasma exosomal microRNAs in these diseases were determined. METHODS The expression of microRNAs derived from plasma exosome of patients with PsA (n=30), PV (n=15), RA (n=15), GA (n=15), and healthy controls (n=15) was evaluated via sequencing. Function analysis of common expressed microRNAs was conducted by the Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analyses. Coexpression analysis was conducted to identify novel and significant genes and proteins by using the Search Tool for the Retrieval of Interacting Genes (STRING). A systematic literature review was conducted to uncover the role of the common microRNAs in the pathogenesis of PsA, PV, RA, and GA. RESULTS A total of 36 common expressed microRNAs were detected in patients with PsA, PV, RA, and GA. The most significantly enriched biological processes, cellular components, and molecular functions were "homophilic cell adhesion via plasma membrane adhesion molecules," "CCR4-NOT complex," and "calcium ion binding," respectively. "Antigen processing and presentation" was the most significantly enriched pathway. A total of 91 validated coexpressed gene pairs were identified and 16 common expressed microRNAs and 85 potential target genes were screened based on Cytoscape. Of 36 common expressed microRNAs, 5 microRNAs, including hsa-miR-151a-3p, hsa-miR-199a-5p, hsa-miR-370-3p, hsa-miR-589-5p, and hsa-miR-769-5p, were considered to be connected with the common pathogenesis of PsA, PV, RA, and GA. Systemic review revealed that the roles of these 5 microRNAs are related to immune disorder and bone injury, which matches the conclusion from GO and KEGG analyses. CONCLUSION (1) Both immune disorder and bone metabolic dysregulation could be the shared mechanism in the development of PsA, PV, RA, and GA. (2) Immune dysfunction is involved in GA. Our study may shed new light on the diagnosis and treatment strategy of these autoimmune diseases and GA, which warrants further studies.

Abstract
BACKGROUND The purpose of this study was to determine the number of cases needed to achieve the level of competence for percutaneous endoscopic lumbar diskectomy (PELD) via the bi-needle technique using the cumulative summation test for learning curve (LC-CUSUM). METHODS A retrospective design was used. We included 60 patients who underwent a single-level PELD via the bi-needle technique performed by a single surgeon. The surgeon had 5 years of experience in open surgery including the transforaminal endoscopic spine system and Yeung endoscopic spine system but no experience in the bi-needle technique. Surgery success was defined as an operative time <60 minutes, and the acceptable procedure was completed within 3 times of C-arm fluoroscopies. The LC-CUSUM was used to analyze the data. RESULTS The average operative time for PELD via the bi-needle technique was 58.3 ± 12.4 minutes. The mean operative time was 65.7 ± 12.1 minutes in the early learning period (30 cases) and 51.0 ± 7.5 minutes in the late learning period (30 cases) (P < 0.05). On the basis of the evaluation indexes of the operative time and radioactive exposure, the LC-CUSUM signaled proficiency for the bi-needle technique at the 50th-54th operation. Seven cases of complications were observed during the whole learning process, with 6 in the early period and 1 in the late period (P < 0.05). CONCLUSIONS The novel bi-needle technique is safe and effective for PELD with appropriate patients, and the learning curve is acceptable. A substantial learning period (50-54 cases) is needed before a spine surgeon can master the bi-needle technique.

Abstract
At present, there is still a underrecognition of the standardization work of acupuncture and moxibustion and the confusion of the basic theory. In order to better advance the next step, it is necessary to review the way and clarify the understanding. Based on the definition, principles and methods of standardization, combined with the practice of standardization of acupuncture and moxibustion, this paper analyzes the relationship between standardization and modernization, standardization and individualization diagnosis and treatment, modern standards and traditional classics, as well as standard development and research, it is proposed to base on the development of disciplines, objectively analyze the different needs at home and abroad, as well as scientific research and clinical practice, and clarify the true purpose of standardization of acupuncture and moxibustion. Standard cannot be simply developed on the base of the individual characteristics of acupuncture, and it is not possible to simply develop acupuncture with standardized concepts and methods. It is necessary to return to acupuncture itself and re-examine acupuncture and moxibustion from a standardized perspective, e.g.in-depth analysis and reflection on which characteristics of acupuncture need to be standardized, how to standardize. It is proposed that the scientific research should be organically combined with the development of standards, and drafting should be in compliance with the rules and the quality of the standard should be improved, so as to truly promote the development of the discipline of acupuncture.

Abstract
Within a single integrated globalized economy featuring robust fluxes of interregional trades, the world economy is like a giant bathtub containing the world inventory of energy use. Based on different norms or ethic percepts, the energy use of the world economy is reallocated to nations and regions via global supply chain using normative accounting schemes. By combining typical statistics for world economy 2012, a new perspective is presented in this study to look into the energy use of regional economies from the side of genuine final consumers. Parallel to the final-demand-based accounting method, a total-consumption-based multi-region input-output accounting method is developed following the norm of consumption being the ultimate end and purpose of all producing activities. From a total-consumption-based perspective, the energy use of the United States economy is shown in magnitude 1.8 times that of mainland China, compared to a ratio of 88% from a territorial-based perspective. The consumer-product-related trade imbalances of major economies in terms of both currency and energy use are analyzed, with major interregional net trade flows illustrated. While the United States and mainland China are respectively revealed as the leading net exporter and net importer of currency, the energy trade deficit of the latter is in magnitude around four times the energy trade surplus of the former. The trade structures by geography and sector are respectively presented for the United States and mainland China as two distinct economies. It is found that around half of the United States' exports of energy use originate from transport and service industries, while nearly 90% of mainland China's exports of energy use come from heavy industry. The findings are supportive for nations to identify their roles in the global supply chain from the perspective of genuine final consumers and adjust the trade patterns for sustained energy use.

Abstract
Basigin is a well-known extracellular stimulator of fibroblasts and may confer resistance to apoptosis of fibroblasts in vitro under some pathological status, but its exact function in fibroblasts and the underlying mechanism remain poorly understood. The systematic Basigin gene knockout leads to the perinatal lethality of mice, which limits the delineation of its function in vivo. In this study, we generated a fibroblast-specific Basigin knock-out mouse model and demonstrated the successful deletion of Basigin in fibroblasts. The fibroblast-specific deletion of Basigin did not influence the growth, fertility and the general condition of the mice. No obvious differences were found in the size, morphology, and histological structure of the major organs, including heart, liver, spleen, lung and kidney, between the knockout mice and the control mice. The deletion of Basigin in fibroblasts did not induce apoptosis in the tissues of the major organs. These results provide the first evidence that the fibroblast-specific Basigin knock-out mice could be a useful tool for exploring the function of Basigin in fibroblasts in vivo.
