Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.

The Cobb angle of the main curve was 50.20°±15.19° preoperatively, 10.91°±6.46° postoperatively , 10.53°±6.42° at 1-year follow-up, and 10.14°±5.95° at the last follow-up, and the difference was statistically significant ( F=45.55, P<0.001), the preoperative and postoperative difference was statistically significant ( t=10.62, P<0.001) with a correction rate of 78.32%±11.41%. The T 1 inclination angle was 16.08°±8.06° before operation, 3.71°±2.40° after operation, 4.05°±1.94° at 1-year follow-up, and 3.97°±2.04° at the last follow-up, and the difference was statistically significant ( F=10.55, P=0.001), the preoperative and postoperative difference was statistically significant ( t=6.37, P<0.001) with a correction rate of 69.56%±25.86%. The neck tilt angle was 7.45°±3.72° before operation, 2.45°±1.12° after operation, 2.75°±0.89° at 1-year follow-up, and 3.10°±2.01° at the last follow-up, and the difference was statistically significant ( F=6.65, P=0.008), in which postoperative correction rate was 57.92%±25.41%, and the difference was statistically significant ( t=4.69, P<0.001). The data of shoulder height difference before operation did not conform to normal distribution (Shapiro-Wilk test, P=0.017), it was 0.97 (0.54, 1.32) cm before operation and 0.53±0.40 cm after operation, and the postoperative correction rate was 50.17%±27.38%, the difference was statistically significant ( Z=3.18, P=0.001). The total score of SRS-22 questionnaire was increased from 4.21±0.29 preoperatively to 4.81±0.17 at 24-month follow-up ( t=7.35, P<0.001). Except for one patient with transient upper limb numbness, the other 13 patients showed no obvious intraoperative or postoperative complications. Conclusion:Both posterior column osteotomy with fusion and posterior hemivertebra osteotomy are effective in the treatment of cervicothoracic scoliosis, and the surgeon can make individual treatment plans according to different conditions.

AL3810, a molecular dual inhibitor of the vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR), has earned the permission of phase II clinical trial for tumor treatment by China FDA. As a reversible ATP-competitive inhibitor, AL3810 targets ATP-binding site on intracellular region of VEGFR and FGFR, whereas, AL3810 lacking interplay with extracellular region of receptors rendered deficient blood-brain tumor barrier (BBTB) recognition, poor brain penetration and unsatisfactory anti-glioma efficacy.

Objective:To explore the mechanism of miR-205-5p/E2F1 signal axis in regulating the glioma U251, U87 radiotherapy resistance.Methods:X-ray gradual ascending and intermittent induction method was used to irradiate the glioma U251 cells to establish U251/TR, U87/TR radiation-resistant cell lines. Then, the morphology, migration, invasion and proliferation abilities of cells (U251/TR, U87/TR radiation-resistant cells and U251, U87 radiation-sensitive cells) were analyzed. Luciferase gene detection system and point mutation technique were employed to analyze the mechanism of miR-205-5p and E2F1 gene activity on U251 and U87 radiation-resistant cell lines.Results:Compared with the radiation-sensitive U251 cells, the radiation-resistant cells U251/TR, U87/TR showed increased proliferation activity, enhanced migration and invasion abilities and decreased apoptosis under X-ray irradiation. miR-205-5p mimics transfection could down-regulate the expression of E2F1 factor in U251/TR cells, inhibit cell proliferation, invasion and migration and increase the radiosensitivity of U251/TR cells. miR-205-5p mimics transfection combined with with E2F1 down-regulation exerted anti-tumor effect and decreased cell tolerance by suppressing the Wnt/β-catenin signaling pathway activity.Conclusions:The glioma radiation-resistant cell line U251/TR, U87/TR can be established by X-ray gradual ascending and intermittent induction method. The miR-205-5p/E2F1 signal axis exerts tumor-suppressing effect through the classical Wnt/β-catenin signaling pathway, which can be used as an therapeutic target to increase the radiosensitivity of glioma.

Objective:To evaluate the feasibility and clinical efficacy of deformed complex vertebral osteotomy (DCVO) technique on the treatment of angular kyphosis of cured spinal tuberculosis.Methods:A retrospective study was performed on patients with angular kyphosis of cured spinal tuberculosis who underwent the DCVO technique or posterior vertebral column resection (PVCR) technique from Jan, 2007 to Jan, 2019. 33 patients were included, 18 males and 15 females, the average age was 39.5±15.0 years old (ranged 9-78 years old). The vertebral deformity in thoracic vertebrae 14 cases, thoracolumbar vertebrae 16 cases, and lumbar vertebrae 3 cases. 20 cases underwent the DCVO technique, while 13 cases underwent PVCR technique. For DCVO group, the multiple malformed vertebrae were considered a malformed complex, and a larger range and angle wedge osteotomy was performed within the complex using the DCVO technique. PVCR technique would resect the whole deformed vertebrae, and subsequently brought the two separated spinal columns together with instruments and titanium mesh. The intro-operative blood loss, operating time and complications were recorded. The radiological measurements included preoperative and postoperative spinopelvic parameters, which including thoracic kyphosis (TK), lumbar lordosis (LL), sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS) and segmental kyphosis. The recovery of neurological function was evaluated by Frankle classification.Results:All patients were followed up for 7-72 months. Comparing with the cases underwent PVCR technique, the DCVO group has a significantly lower blood loss (1315.00±462.57 ml), operating time (293.00±83.86 min) and complications rate (1.5%). At the time of preoperation, postoperation and last follow-up, the deformity angle of DCVO group was 96.80°±6.32°, 29.10°±6.96°and 29.05°±6.49°, which gained an average 69.9% correction rate. The statistical analysis suggested that deformity angle was enormously corrected. And there was an insignificant difference between DCVO group and PVCR group. Meanwhile, the preoperative, postoperative and follow-up TK of DCVO group was 96.96°±29.13°, 37.15°±4.88° and 37.00°±3.89°respectively, whosecorrection rate was 67.1%; LL was 66.70°±21.21°, 42.25°±5.53° and 41.90°±4.98°, which have a significant difference between pre-operation and post-operation/follow-up ( F=23.997, P<0.001) ; SVA was 75.95±18.63 mm, 16.30±6.88 mm and 16.55±7.30 mm. PI was 47.50°±6.12°, 47.35°±5.54°and 47.90°±5.93°, PT was 37.25°±9.63°, 18.50°±1.99° and 19.00°±1.65°; SS was 10.25°±8.27°, 29.15°±5.91° and 28.85°±5.77°. The sagittal and spinopelvic parameters of two groups improved significantly at postoperation and follow-up. No obviously difference of spinal parameters was found between two groups at preoperation and postoperation. Both groups have cases with dysneuria. And all of these cases achieved different degrees of recovery at follow-up. Conclusion:The use of DCVO technique for the treatment of post-tubercular angular kyphosis is safe and efficiency. DCVO leads a better clinical outcomes and lower complication rate than VCR technique.

BACKGROUND:There are few studies concerning estrogen receptorβgene, and its mechanism of regulating the bone metabolism is stil unclear now. OBJECTIVE:To analyze the effect of estrogen receptorβ(ERβ) silencing on the expressions of transforming growth factorβ1 (TGF-β1) and bone morphogenetic protein 2 (BMP-2) in human osteoblasts METHODS:There were three groups:blank control group (hFOB 1.19 uninfected with any retrovirus);negative control group (containing invalid interference fragment ERβ-shRNA-nc);optimal RNAi group (ERβ-shRNA-3). ERβ-shRNA retroviral vectors in the optimal RNAi group were used to transfect human osteoblasts fol owed by resistance screening and cel expansion. MTT assay was used to detect the proliferative activity of ERβ-silenced osteoblasts. Then under estrogen intervention, the stable inhibition rate of ERβwas determined using western blot assay, and the expressions of TGF-β1 and BMP-2 in human osteoblasts after ERβsilencing were detected by RT-PCR technology and western blot assay. RESULTS AND CONCLUSION:Human osteoblasts that were stably transfected by ERβ-shRNA-3 retroviral vector was selected successful y, and ERβsilencing had no significant influence on the cel proliferation (P>0.05). Under the interference of estrogen, the silencing efficiency of ERβprotein was (93.11±0.57)%(P<0.05), and after ERβsilencing, the expressions of TGF-β1 and BMP-2 were increased by (26.65±3.81)%and (16.62±1.71)%at mRNA level, and increased by (23.79±3.76)%and (18.08±3.20)%at protein level (both P<0.05). In conclusion, ERβmay play an important role in bone metabolism by regulating the expressions of TGF-β1 and BMP-2.

Objective To compare the minimum 5?year follow?up outcomes of surgical management by posterior only, anterior only and combined posterior and anterior approaches for lumbar tuberculosis in adults, evaluate the mid?term follow?up results of the surgery for the treatment of lumbar tuberculosis and explore its advantages and indications. Methods From Jun 2004 to Jan 2010, 311 adult patients with lumbar tuberculosis were treated surgically. The clinical data of 137 cases that met the enrolled criteria and had integrity following?up data was analyzed retrospectively. It included the patients who had the surgical indication of the posterior only surgery but underwent the anterior only or the combined posterior and anterior ap?proaches before 2008. There were 83 cases of male and 54 cases of female. The age ranged from 20 to 75 years, with a mean of 65.6 years. Among these patients, 63 cases were treated with single?stage posterior debridement, interbody fusion and instru?mentation (the posterior group); 42 cases were treated with posterior instrumentation, and anterior debridement and bone graft in a single or two?stage procedures (the combined group) and 32 cases were treated with anterior debridement and strut graft?ing with instrumentation (the anterior group). Trauma index (the operation time, blood loss, the length of hospital stay, compli?cations);imaging parameters (Segment kyphotic angle, corrective rate, loss angle, bone fusion time) and the quality?of?life indi?cators (Oswestry Disability Index、Frankle grade、visual analogue scale、Macnab score) were compared among three groups. Re?sults The mean operation time, mean blood loss and the complications rate were (207.9 ± 30.9) min, (409.5 ± 107.9) ml and 12.95%in the posterior group;(270.7±32.0) min, (649.0±120.0) ml and 30.95%in the anterior group;(349.7±38.9) min, (840.0± 168.7) ml and 25%in the combined group. The operation time, blood loss and the complications rate of the posterior group were less than the anterior group and the combined group, and the difference was significant;The combined group consumed the longest operation time, associated with the most intraoperative blood loss, the highest complication rate and the longest hospital stay among the three groups, and the difference was significant. The correction rate of kyphosis achieved of the anterior group ( 52%± 5.45%) was significantly inferior to the posterior group (74%±5.04%) and the combined group (69%±7.95%), while the loss of cor?rection in the anterior group (2.5°) was higher than both the posterior group (0.8°) and the combined group (1.1°), and the differ?ence was significant. The average follow?up was(6.5±1.96)years (range, 5-11). The mean bone fusion time of the posterior group, the anterior group and the combined group were (6.0±1.5) months, (6.2±1.3) months and (6.5±1.6) months respectively, and there was no statistic difference. After the surgery, the quality of life was improved obviously in all patients. At the time of the latest fol?low?up, the improvement rate of the ODI,VAS and the excellent and good rate according to the Macnab score were 80.6%±2.1%, 81.7%± 1.6%and 95.24%in the posterior group;79.8%± 1.5%, 79.7%± 2.0%and 92.95%in the anterior group;81.3%± 1.1%, 79.9%±0.8%and 90.63%in the combined group. There was no significant difference among the groups in the improvement rates of the ODI, VAS, Frankel grade and the excellent and good rate of the Macnab score. Conclusion The Mid?term follow?up of the different surgical procedures for the treatment of the lumbar tuberculosis in adults were basically satisfactory. Compared with the traditional surgery, the posterior?only surgery is a safe, minimally invasive and effective method in the management of monoseg?ment lumbar tuberculosis in adults.
