The application of new-generation information technologies such as big data, the internet of things(IoT), and cloud computing in the traditional Chinese medicine(TCM)manufacturing industry is gradually deepening, driving the intelligent transformation and upgrading of the TCM industry. At the current stage, there are challenges in understanding the extraction process and its mechanisms in TCM. Online detection technology faces difficulties in making breakthroughs, and data throughout the entire production process is scattered, lacking valuable mining and utilization, which significantly hinders the intelligent upgrading of the TCM industry. Applying data-driven technologies in the process of TCM extraction can enhance the understanding of the extraction process, achieve precise control, and effectively improve the quality of TCM products. This article analyzed the technological bottlenecks in the production process of TCM extraction, summarized commonly used data-driven algorithms in the research and production control of extraction processes, and reviewed the progress in the application of data-driven technologies in the following five aspects: mechanism analysis of the extraction process, process development and optimization, online detection, process control, and production management. This article is expected to provide references for optimizing the extraction process and intelligent production of TCM.

ObjectiveThere is still controversy about which internal fixation method should be used in oblique lateral interbody fusion (OLIF). This paper aims to compare the biomechanical stability of OLIF with different internal fixation methods.MethodsA 31-year-old healthy male volunteer was selected to have a 64-slice spiral CT scan of his lumbar spine. Mimics 19.0, Geomagic Studio 2013, SolidWorks 2017 and other software were used to build a three-dimensional model of L3-L5, and OLIF surgery was simulated to build OLIF finite element models with five different fixation methods: pedicle screw (PS), lateral single rod screw (LSRS), lateral double rod screw (LDRS), lateral single rod screw+ipsilateral translaminar facet screw (LSRS+ITLFS), lateral single rod screw+contralateral translaminar facet screw (LSRS+CTLFS). After validating the validity of the model, the motion modes of spinal flexion, extension, lateral bending and rotation were simulated, and the fixed segment activity and stress distribution characteristics of each model were compared.ResultsIn terms of fixed segment activity, PS had the best fixation effect, and its range of motion (ROM) was the smallest in all 6 modes. The ROM of the vertebral body was maximized when the LSRS was fixed in all directions. LSRS+ITLFS, LSRS+CTLFS and PS had the similar ROM. In terms of maximum stress of cage, PS had the minimum one except in the left bending. LSRS+ITLFS had little stress in all directions except in flexion; LSRS+CTLFS had little stress in all directions except in extension. In terms of the maximum stress in internal fixation, PS had the least one in all directions; LSRS+CTLFS followed, and the maximum stress appeared in extension and right bending (123.05MPA and 91.74MPA, respectively).ConclusionIn OLIF surgery, PS has the best biomechanical effect. LSRS+CTLFS has the similar effect and its clinical operation is simple with relatively small surgical injury, thus providing a reference for clinical choice.

OBJECTIVETo establish osteoblast-osteoclast cell co-culture system in a Transwell chamber, and detect cell viability of osteoblasts and osteoclasts in system.

METHODSOsteoblast MC3T3-E1 and mouse monocytes RAW264.7 were cultivated in vitro. RANKL-induced mouse RAW264.7 monocytes differentiated into mature osteoclasts, osteoblast-osteoclast cell co-culture system was established in Transwell chamber. Cell activity of osteoblasts and osteoclasts were detected by CCK-8 experimenting, Alizarin Red staining, TRAP staining. The expression of OPG, ALP, RANKL, TGF-b1 gene and RANKL protein in osteoblast MC3T3-E1 were detected by PCR, Western-Blot methods. Also, the expression of RANK, NF-κB in gene and protein level in osteoclast were measured through the same method respectively.

RESULTSThe co-culture system of Mouse MC3T3-E1 cells and RAW264.7 cell were established in Transwell chamber. Co-culture system affected cell division activities of osteoblasts and osteoclasts. Differentiation of osteoblasts were increased, while differentiation of osteoclast division were slight decreased under microscope observation. OPG (0.65±0.08) and ALP (0.16±0.01) gene expression of co-culture system were less than single culture OPG(1.00±0.08) and ALP (1.01±0.16); TGF-b1(4.42±0.21) and RANKL(4.12±1.04) of osteoblasts in co-culture system were higher than TGF-b1(1.00±0.10) and RANKL(1.00±0.09) under single culture. However, gene expression of RANK(0.63±0.06) and NF-κB(0.64±0.08) in co-culture system were decreased than RANK(1.00±0.08) and NF-κB(1.00±0.09), in single culture, and had significant differences. Similarly, protein expression of OPG(0.43±0.05) and NF-κB(0.59±0.05) of co-culture system were less than OPG(0.84±0.06) and NF-κB(1.13±0.03) of single culture. While RANKL protein expression (0.54±0.03)of co-culture system was more than single culture RANKL(0.31±0.03), and had statistically differences, which was in agreement of the trend of gene expression change.

CONCLUSIONSCo-culture system of mouse MC3T3-E1 cells and RAW264.7 cell was viable in Transwell chamber, and the activity of osteoblasts is higher than osteoclasts in co-culture system.

BACKGROUND: Posterior internal fixation is one of the most common methods for thoracolumbar fractures. There is a lack of systematic evaluation about the efficacy of injured vertebra pedicle screw fixation(IVPSF)versus short-segment pedicle instrumentation (SSPI) for thoracolumbar fracture. OBJECTIVE: To compare the clinical outcomes of IVPSF and SSPI for single thoracolumbar fracture through a METHODS: A computer-based on-line research of PubMed, Medline, Embase, Cochrane Library, CNKI, and WanFang databases was performed for the studies regarding IVPSF versus SSPI for thoracolumbar fracture from 1990 to 2016. meta-analysis. The randomized controlled trials and cohort studies were collected based on the strict criteria of inclusion and exclusion. A meta-analysis was conducted on Revman5.3 sofeware. RESULTS AND CONCLUSION: (1) Eleven articles were enrolled, including 5 English and 6 Chinese ones, involving 689 patients (328 cases for IVPSF and 361 cases for SSPI). (2) The meta-analysis indicated that the operation time, blood loss and mean hospital stay showed no significant differences between two groups. IVPSF showed more effective than SSPI in the kyphotic angle correction and anterior vertebral height recovery at postoperation and 1-5 years of follow-up. Moreover, the incidence of postoperative fixation failure in IVPSF was lower than that in SSPI. (3) These findings suggest that IVPSF that reduces the postoperative fixation failure rate for thoracolumbar fractures provides better kyphosis correction and restoration of anterior vertebral height at post-operation and 1-5 years of follow-up.

OBJECTIVETo investigate the diagnostic value of clinical manifestation, laboratory examination and imaging changes for pyogenic spondylitis and to summarize the clinical characteristics of patients with pyogenic spondylitis.

METHODSThe clinical data, of 20 patients with pyogenic spondylitis were diagnosed by histopathological examination from March 2012 to March 2015, were retrospectively analyzed. There were 9 males and 11 females, aged from 43 to 72 years old with an average of 58.9 years. Included 3 cases of cervical vertebrae, 7 cases of thoracic vertebrae, 10 cases of lumbar vertebrae. Patients of blood analysis, erythrocyte sedimentation rate(ESR), C reactive protein(CRP), X rays, CT and MRI were performed before treatment. Visual analogue scale (VAS) was used to evaluate the pain of patients suffering from vertebral pain.

RESULTSAll the patients had suffered from vertebral pain before treatment. VAS was 9 points in 4 cases, 8 points in 6 cases, 7 points in 1 case, 3 points in 6 cases, and 2 points in 3 cases. Among them, 7 patients complicated with neurological symptoms, 11 with aggravating night pain, 10 with fever. WBC and Neutrophil count (NEU) of 5 cases were increased and other 15 cases were normal;CRP of 19 cases were increased and 1 case was normal;ESR of all 20 cases were increased. X rays showed the intervertebral space narrowing in all 20 cases, 13 cases complicated with destruction of vertebral body; CT showed the lesions of vertebral body in the 20 cases and complicated with destruction, sclerosis of sclerotin; MRI showed that the lesions of the vertebral body in the T1 image had uneven medium low signal, in the T2 image of the 16 cases had uneven high signal and 2 cases had uniform and high signal, 2 cases had main high signal compliated with mixed signal. Thirteen patients underwent surgical treatment and 7 patients received conservative treatment, and the patients left hospital while VAS had significantly improved after treatment.

CONCLUSIONSPyogenic spondylitis is easy to be misdiagnosed or missed in clinic. It can be combined with the clinical manifestations, laboratory examination and imaging characteristics in order to make a definite diagnosis for purulent spondylitis in early.

OBJECTIVETo identify risk factors associated with patients suffered multiple level osteoporosis vertebral compression fractures(OVCFs).

METHODSFrom March 2011 to March 2015, 199 patients suffered osteoporotic were classified into multiple level OVCFs group and single level OVCF group. Multivariate logistic regression analysis were performed to identify risks factors associated with multiple level OVCFs.

RESULTSAll the patients underwent OVCF, including 71 multiple level OVCFs and 128 single level OVCF. There were no differences in the age, gender, BMI, hypertension and diabetes between two groups. While multiple level OVCFs were associated with spinal deformity index SDI[(2<=SDI<4, OR=2.587, 95% CI(1.148, 5.828);SDI>=-4, OR=7.775, 95% CI(3.272, 18.478)], BMD[(T<-4.5SD, OR=2.608, 95% CI(1.038, 6.551)].

CONCLUSIONSSDI and BMD might be the risk factors for multiple level OVCFs.

OBJECTIVETo establish a method of detecting spinal tuberculosis (TB) infection by enzyme-linked immunospot (ELlSPOT) assay and evaluate the value of CFP10/ESAT6 fusion protein for diagnosis of spinal TB.

METHODSSuspected spinal TB patients were prospectively recruited in two hospitals (First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine; Nanfang Hospital, Southern Medical University) from May 2012 to December 2013. Data on clinical characteristics of the patients and conventional laboratory results were collected. Compare and analyze the positive detection rate in spinal TB diagnosis by different methods including ELISPOT detection and conventional detection methods.

RESULTS47 patients with spinal TB had available biopsy or surgical specimens for histopathological examination and 41 specimens had pathological features consistent with a diagnosis of TB infection. Among the spinal TB patients and non-TB disease patients,the overall sensitivity, specificity, positive predictive value, and negative predictive value of the ELISPOT assay in spinal TB diagnosis were 82.7%,87.2%,89.6%, and 79.1%,respectively; the 4 indexes of the PPD skin test were 61.5%, 46.2%, 60.4%, and 47.4%, respectively;those of the antibody detection were 55.8%, 61.5%, 65.9%, and 51.1%. The positive rate of ELISPOT was significantly higher than those of PPD skin test and antibody detection test (82.7% vs. 61.5%, Χ² =5.786, P=0.016; 82.7% vs. 55.8%, Χ² =8.847, P=0.003), but not significantly different from the positive rate of pathological examination (82.7% vs. 87.2%, Χ² =0.396, P=0.529). Moderate agreement was found between pathological examination and the ELISPOT assay (87.2%, Κ=0.498, P=0.001).

CONCLUSIONWith high sensitivity and specificity, the ELISPOT assay using CFP10/ESAT6 fusion protein as antigen is an effective technique for auxiliary diagnosis of spinal TB.
