The formation of physique was influenced by many factors and was closely related to the disease, especially by the social and cultural factors. According to the characteristics of physique, physique conditioning was conducive to rehabilitation of the disease. It was also the internal evidence for individualized treatment of rehabilitation. Traditional Chinese medicine (TCM) rehabilitation advocated functional rehabilitation as the main treatment purpose. Attentions were paid to promoteqi circulation. The psychological characteristics of the rehabilitation subject were especially emphasized on, in order to improve the therapeutic effect of rehabilitation. There were many classifications of physical evaluations, which were widely used in a variety of clinical diseases rehabilitation. The pathological physique correction and adjustment cannot be ignored in rehabilitation. Therefore, the application of physical evaluation in the guidance of rehabilitation therapy can enrich the content of TCM rehabilitation evaluation. It further improved TCM physical evaluation system to meet the needs for clinical practice and TCM modernization.

Objective To investigate the effect of propentofylline on nerve growth factor (NGF) and IL-1βrelease from rat cerebral cortical astrocytes. Methods Primary cultured rat astrocytes from SD rats (1-3 d,weighing 6-8 g) after 4 passages were randomly divided into 8 groups ( n = 6 wells each): group Ⅰ control (group C); group Ⅱ , Ⅲ, Ⅳ the astrocytes were exposed to propentofylline 10, 100 and 1000 μmol/L respectively (group P1, P2, P3 ); group Ⅴ the astrocytes were exposed to LPS 1 μg/ml and group Ⅵ, Ⅶ, Ⅷ the astrocytes were exposed to propentofylline 10, 100 and 1000 μmol/L in addition to LPS 1 μg/ml (group P1 + LPS, P2 + LPS,P3 + LPS). The astrocytes were then incubated for 3 days in all 8 groups. The concentrations of IL-1β and NGF in the supernatant were detected at 1 and 3 days of incubation using ELISA. Results LPS activated astrocytes resulting in decrease in NGF release and increase in IL-1β release. Propentofylline significantly increased NGF release and decreased IL-1β release from astrocytes incubated alone or with LPS by suppressing activation of astrocytes. Conclusion Propentofylline can enhance NGF release and inhibit IL-1β release from rat cerebral cortical astrocytes.

Aim To investigate the effect of intrathecal injection of fluorocitrate(Fc)on mechanical and thermal hyperalgesia induced by complete Freund's adjuvant(CFA)injection in rats.Methods The mechanical withdrawal threshold(MWT)and thermal withdrawal latency(TWL)were measured before and after CFA or Fc treatment.The changes of glial fibrillary acidic protein(GFAP)and OX-42(a microglial marker)expression in the spinal cord dorsal horn were evaluated by immunohistochemistry analysis.Results Rats with CFA-induced arthritis showed mechanical allodynia and thermal hyperalgesia,which was correlated with the increased GFAP and OX-42 expression in the spinal cord dorsal horn.Intrathecal injection of Fc markedly suppressed CFA-induced thermal hyperalgesia and mechanical allodynia.Fc significantly attenuated the activation of GFAP and OX-42 in the spinal cord dorsal horn.Conclusions The glia activation in spinal cord is closely related to the progress of CFA-induced peripheral hyperalgesia.Fc may exert antihyperalgesic effect by inhibiting the activation of astrocyte and microglia.

Objective To evaluate the role of gliocytes in the spinal cord in the development of inflammatory pain (IP) in rats. Methods Adult male SD rats weighing 180-220 g were used in this experiment. A catheter was implanted in the subarachnoid space according to the method described by Yang. Animals with abnormal motor function of the hindlimb after intrathecal (IT) catheter implantation were excluded. IP was induced by subcutaneous (sc) injection of complete Freund's adjuvant (CFA) 50 μl at the lateral side of the ankle joint of the right hindpaw. Sixty-five rats were randomly divided into 5 groups ( n = 13 each): group I IP control normal saline (NS) 50μl was injected sc instead of CFA; group II IP; group IE PC (IT) + IP control fluorinated citric acid (FC, a gliocyte metabolism inhibitor) 1 nmol/10μl was injected IT at 15 min before NS 50 μl sc injection; group IV NS (IT) + IP and group V FC (IT) + IP. The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured 2 d before induction of IP (T_0, baseline) .before and at 2, 4, 6, 8, 10, 12, 24 and 26 h (T_(1-9)) after sc NS or CFA injection. Five enimals in each group were killed at T_5 (8 h after sc NS/CFA injection) and the lumbar segment (L_(4,5)) was removed for determination of glial fibrillary acidic protein ( CFAP) and OX-42 expression by immuno-histochemistry. Results In group Ⅱ and Ⅳ sc CFA significantly decreased MWT and TWL. Mechanical and thermal hyperalgegia induced by sc CFA was significantly suppressed by intrathecal FC in group V . IP significantly increased GFAP and OX-42 expression in the spinal cord. Intrathecal FC significantly attenuated IP-induced up-regulation of GFAP and OX-42 expression in the spinal cord. Conclusion The activation of gliocytes in the spinal cord is involved in the development of CFA-induced hyperalgesia in rats.

Objective: To investigate the variation of γδ T cells from healthy human peripheral blood(PB)and neonatus cord blood (CB)in proliferation and subtypes with isopentenyl pyrophosphate(IPP), and to acquire enough γδ T cells possessing distinct characteristics for experimental study.Methods: Mononuclear-cells from peripheral blood and cord blood induced by IPP were stained separately with monoclonal antibodies,which were fluorescein-labeled,and then used for assaying the expressing condition of surfaco molecules,as well as to evaluate the variation of γδ T cells on the percentage, subtypes and pbenotypes by FCM.Results:γδ T cells only account for a small proportion in both PB and CB.However,there was a significant difference in the heterogeneity between peripheral blood and cord blood γδ T cells.Vγ9Vδ2 T cells were dominant in peripheral blood γδ T cells.Most of Vγ9Vδ2 T cells in fresh isolated PBMC were central memory-type(CD27~+ CD45RA~-)and effector memory-type(CD27~-CD45RA~-)with IPP, PB γδ T cells proliferated strongly;The effector memory-typo(CD27~-CD45RA~-)turned into the main subtype in all Vγ9Vδ2 T cells,and HLA-DR and B7 molecules were highly expressed on the populations.But the cord blood γδ T cells showed rather complex subgroup heterogeneity,and Vγ9Vδ2 T cells were almost na(i)ve-type(CD27~+ CD45RA~+); Though γδ T cells were expanded(the percent of γδ T cells was increased),and Vγ9Vδ2 T cells were differentiated towards central memory-type and effector memory-type on day 14 with IPP,most of γδ T celLs still remained in the phase of na(i)ve-type(CD27~+ CD45RA~+).Conclusion:Tbere lies great differences of γδ T cells in quantity and subtypes between healthy person peripheral blood and neonatus cord blood.Peripheral blood γδ T cells can be activated and proliferated with IPP, while cord blood γδ T cells have the potential to deferentiate into director memory-type which can be used for experimental and clinical study with the synergy of corresponding cytokines.The immuno-regulation and effector function will be reported in other papers.

Objective:To analyse the biological function of anti-IL-6Rβ(gp130) monoclonal antibody and its regulatory effect on IL-6 signaling.Methods:Biological characteristics of anti-IL-6Rβ(gp130) mAb were assessed by Western blot analysis, capture ELISA and peptide ELISA .The phosphorylation of STAT 3 was tested by Western blot analysis in IL-6-stimulated U266/RA-FLS/RA-PBMC with or without anti-IL-6Rβ(gp130) mAb treatment.Results:3 strains of mouse anti-human gp130 mAb were with high affini-ty and different binding epitopes , the kaff of 10A1 was 2.62E-10.In U266, RA-PBMC and RA-SFMC, IL-6 signaling highly activated STAT3 which could be inhibited by anti-gp130 mAb.Conclusion: Anti-IL-6Rβ( gp130 ) mAb might have different binding epitopes and could affect IL-6 stimulated phosphorylation of STAT3, which provides a preliminary experiment for analyse the correlation of IL-6 signaling and RA .

Objective? To analyze the current situation of clinical research on cardiac rehabilitation in China from 2008 to 2018, so as to provide references for clinical research and practice in this field. Methods? CNKI and Wanfang database were used as retrieval tools to retrieve published clinical research literature on cardiac rehabilitation. Bibliometric methods were used to analyze the annual distribution, regional distribution, authors, journals and fund support of the published literature. Results? A total of 603 articles were included in this study and the numbers of articles and funds showed a rapid growth trend. Both of them were widely distributed but not balanced in different regions. Among the 582 first authors, 563 authors were with one article, accounting for 96.74%. 40 articles published by 19 core authors who have published over 2 articles were accounting for 6.63%. The co-authorship rate was 65.51% and the degree of cooperation was 2.50. There were 218 journals involved and only 5 of the 15 core journals belonged to the core journals of science and technology of China in 2018. Conclusions? From 2008 to 2018, the clinical research of cardiac rehabilitation in China was in a rapid development stage. Researchers in this field were highly collaborative but dispersive and lack of sustainability. The quality of core journals was unsatisfactory. It is suggested that more attention should be paid, more technology and talents should be input and balanced, fund supports should be provided to produce high quality researches and high level results.

Objective To explore the difference between T cells in the synovial fluid and peripheral blood in patients with rheumatoid arthritis(RA). Method Samples from 22 patients were studied. The differentiation and activation markers expressed on T cell surface were detected by immunofluorscence using flow cytometer. The specific proliferation of collagen Ⅱ and heat shock protein 70 was analyzed using standard 3H-TdR incorporation method. Restricted V beta usage of these T cell was analyzed by semi-quantitied RT-PCR. Results The majority of the T cell subsets in the synovial fluid were demonstrated to be CD4 and CD8 positive cells in which (40?10)% were CD4 positive and (36?16)% were CD8 T cells respectively. The ratio between CD4 and CD8 was much lower than that found in the PBL of RA patients. The percentage of CD3+/CD25+ T cells was (16?6)%. The specific proliferation of collagen Ⅱ and HSP70 to CD3+/CD25+ T cell was higher than that of CD3+/CD25+ negative T cells. The T cell receptor expressed on the T cells from both peripheral blood and synovial fluid were tested for ?? TCR (70?26)%. However, the T cells in the synovial fluid showed V?14,16 and 17 restriction. Conclusion The data here reported indicates that T cell subsets in the synovial fluid and peripheral blood circulation in patients with rheumatoid arthritis are different. The T cells in the synovial fluid demonstrates more activation and higher reactivation to collagen Ⅱ and HSP70. The TCR of T cells showes V?14,16 and 17 restriction.

Objective:To explore the impact of robot assisted total hip arthroplasty (THA) on the accuracy of prosthesis placement and its clinical efficacy.Methods:A total of 432 patients (549 hips) who underwent robot-assisted primary THA for various diseases of the hip in the Department of Orthopaedics of the Fourth Medical Center of the PLA General Hospital from August 2018 to October 2022 was retrospectively analyzed. There were 174 male and 258 female with an average age of 54.2±12.7 years old and body mass index (BMI) of 23.2±4.3 kg/m 2. There were 301 left hips and 248 right hips. All patients were operated under general anesthesia using the standard posterior lateral surgical approach to THA. The Harris hip score (HHS), forgotten joint score (FJS), the Western Ontario and McMaster University (WOMAC) osteoarthritis index and patient satisfaction were used to evaluate the clinical outcomes. The anterior inclination, abduction angle, lower extremity discrepancy and the position of the center of rotation (COR) of the hip joint were radiographically accessed preoperatively, intraoperatively and postoperatively. The composition ratio of the acetabular cup in the safe zone was also calculated. Results:Five hundred and forty-nine consecutive hips (432 patients) underwent robotic-assisted THA with a mean follow-up of 23.6±16.2 months. The mean operative time was 86.2±35.4 min, and the mean blood loss was 236.7±94.5 ml. At the last follow-up, the mean HHS score for this group was 91.4±15.4, the WOMAC score was 8.4±6.5, the FJS score was 77.4±23.4, and the satisfaction score was 9.1±2.7 points. The mean postoperative measurement of acetabular cup anteversion was 21.2°±4.8° and abduction was 40.8°±4.3°. About 93.7% (511 patients) had an acetabular cup within the safety zone of ±10° of the target angle, and 84.6% (464 patients) had an acetabular cup within the safety zone of ±5° of the target angle. A total of 4 complications occurred. Acute periprosthesis infection happened in a case of developmental dysplasia of the hip (DDH) and was cured by DAIR (debridement, antibiotics, irrigation, retention of prosthesis). One case of thigh pain of unknown reason was treated with a revision operation, during which no loosening or malposition of the prosthesis was found. After replacing the femoral head component no pain was complained by the patient. One case of hematoma and nerve compression was considered to be caused by blood vessels injury when a titanium cable was used to fix the distal femoral fracture during the surgery. The nerve injury returned to normal within 1 month. One case of dislocation happened immediately after surgery and was revised by replacing a different head. The patient was fully recovered. In addition to software and mechanical failures of the robot itself, complex hip joint diseases would be a risk factor for the termination of robot assisted surgery due to the occurrence of adverse events related to robots in 16 hips. Considering the existence of a certain termination rate in robot assisted surgery, sufficient preparation should be made when applying robot assisted technology in complex hip joint diseases.Conclusion:In robotic-assisted THA, preoperative planning can be achieved with precise and reproducible acetabular cup positions, significantly increasing the chance of locating the acetabular cups in the safety zone, and obtaining satisfactory results in restoring COR and leg length.
