BACKGROUND:It is wel-known that vitamin E holds antioxidant capacity, but whether other growth factors have the same effect on endplate chondrocytes has not yet been reported. OBJECTIVE:To observe the effect of different growth factors on the antioxidant ability of endplate chondrocytes in the intervertebral disc. METHODS:Endplate chondrocytes were primary cultured, and then divided into four groups, including blank control, serum deprivation, hydrogen peroxide stimulation and hydrogen peroxide stimulation combined with different growth factors groups. The 4th group was subdivided into insulin-like growth factor-1, basic fibroblast growth factor, transforming growth factorβ, forskolin and vitamin E groups. The expression levels of caspase-3, matrix metal oproteinase 13 and 3, inhibitor of metal oproteinase 1 as wel as thrombin 4 and 5 were detected by real-time PCR. Cel apoptosis was analyzed through apoptosis kit and flow cytometry. Cel synthesis and secretion were detected by western blot assay. The total antioxidant capacity and the hydrogen peroxide content were determined by kit, and then statistical y analyzed. RESULTS AND CONCLUSION:Different growth factors had significant differences in the endplate chondrocyte apoptosis, secretion and antioxidant capacity. To conclude, transforming growth factorβand forskolin do further damage to the cel s stimulated by hydrogen peroxide, while insulin-like growth factor-1 and vitamin E expose protective effect on the injured cel s.

Objective: To explore the clinical and anatomical characteristics of coronary slow lfow (CSF) in relevant patients.
Methods: We summarized the patients without coronary angiography (CAG) proved coronary stenosis (stenosis < 40%) while with TIMI indicated CSF in our hospital from 2013-01 to 2015-01. The patients were divided into 2 groups: CSF group, n=56 patients having at least 1 major coronary artery with TIMI frame counts > 27 and Control group,n=55 patients with normal coronary lfow. The related laboratory indexes were examined and relationship between MCV and CSF was studied by multi-logistic regression analysis.
Results: In CSF group, MCV 90.4 (87.48, 92.65) fL and RDW-CV 12.5 (12.30, 13.18) % were lower than those in Control group 92.3 (90.1, 94.3) fL and 13(12.7, 13.4) %,P<0.05; while MCHC 337 (332, 347) g/L and the number of left circumlfex distal braches involved 3 (2, 4) were higher than those in Control group 327.5 (322, 338) g/L and 2 (2, 3),P<0.05. Multi-logistic regression analysis showed that MCV was negatively related to CSF (partial regression coefficient= -0.138, P=0.015), Spearman rank correlation analysis presented that MCV was negatively related to TIMI frame counts (r= -0.201, P=0.009).
Conclusion: Deformability of red blood cells might be involved in pathogenesis of CSF in relevant patients.

Alcohol liver disease (ALD) is the most common disease resulting in liver injury in the world. Inflammatory response is an important reason for liver injury in ALD. After being absorbed into the intestines, alcohol can increase the amount of intestinal endotoxin which enters the bloodstream through enterohepatic circulation and activates Toll-like receptor 4 in liver Kupffer cells to release inflammatory factors. The inflammatory factors including tumor necrosis factor-α induce liver injury, while interleukin-6 (IL-6) and interleukin-10 (IL-10) protect the liver through regulating inflammatory response. IL-6 can increase the expression of various anti-injury genes in hepatocytes through activating signal transducer and activator of transcription 3 (STAT3), and IL-10 can inhibit liver inflammatory response through activating STAT3 in Kupffer cells. The processes of imbalance and rebalance between proinflammatory factors and anti-inflammatory factors are the development and prognosis of ALD. This article systematically reviews the role of inflammatory factors in the development and progression of ALD from the perspective of inflammatory response.

OBJECTIVETo observe the effect of Huogu II formula compatible with different channel ushering drugs on the homing of bone marrow stem cells of osteonecrosis of the femoral head (ONFH) induced by liquid nitrogen freezing in rabbits and discuss the mechanism for preventing and treating ONFH.
METHODThe ONFH model was established by liquid nitrogen freezing of 84 rabbits. They were randomly assigned to the model group and the Huogu II formula group and groups of Huogu II formula combining with Achyranthis Bidentatae Radix, Asari Radix et Rhizoma, Angelicae Pubescentis Radix, Platycodonis Radix. The remaining 14 rabbits were sham-operated. During the course of ONFH modeling, all of the rabbits were subcutaneously injected with recombinant human granulocyte colony-stimulating factor (rhG-CSF)(30 microg x kg(-1) x d(-1), for consecutively 7 days). Meanwhile, normal saline and decoction of the formulae were orally administrated respectively. WBC was counted in peripheral blood before and after the injection of rhG-CSF. HE stainings at the 2nd and the 4th weeks after the modeling were adopted to observe histopathological changes, vascular morphology was observed by ink perfusion, BrdU and SDF-1 were determined by immunohistochemical assay in femoral heads of the left hind leg.
RESULTCompared with the sham-operated group, the Huogu II formula group showed decrease in the ratio of empty lacuna and increase in vessel area, number of BrdU positive cells and SDF-1 level. In comparison with the model group, the Achyranthis Bidentatae Radix group displayed decreasing empty lacuna ratio and increasing vessel area at the 4th week and increasing SDF-1 at the 2nd week; the Platycodonis Radix group revealed a notably increasing empty lacuna ratio and a sharp decrease in the number of BrdU positive cells at 4th week; Asari Radix et Rhizoma and Angelicae Dubescentis Radix groups showed no remarkable change.
CONCLUSIONHuogu II formula can promote the directional homing of bone marrow stem cell to the necrosis area. Channel ushering drug achyranthes can further boost above effects of Huogu II formula.

Elucidating the active components of traditional Chinese medicine(TCM)is essential for understanding the mechanisms of TCM and promote its rational use as well as TCM-derived drug development.Recent studies have shown that surface plasmon resonance(SPR)technology is promising in this field.In the present study,we propose an SPR-based integrated strategy to screen and analyze the major active components of TCM.We used Radix Paeoniae Alba(RPA)as an example to identify the compounds that can account for its anti-inflammatory mechanism via tumor necrosis factor receptor type 1(TNF-R1).First,RPA extraction was analyzed using an SPR-based screening system,and the potential active in-gredients were collected,enriched,and identified as paeoniflorin and paeonol.Next,the affinity con-stants of paeoniflorin and paeonol were determined as 4.9 and 11.8 μM,respectively.Then,SPR-based competition assays and molecular docking were performed to show that the two compounds could compete with tumor necrosis factor-α(TNF-α)while binding to the subdomain 1 site of TNF-R1.Finally,in biological assays,the two compounds suppressed cytotoxicity and apoptosis induced by TNF-α in the L929 cell line.These findings prove that SPR technology is a useful tool for determining the active in-gredients of TCM at the molecular level and can be used in various aspects of drug development.The SPR-based integrated strategy is reliable and feasible in TCM studies and will shed light on the eluci-dation of the pharmacological mechanism of TCM and facilitate its modernization.

Annexin A3(ANXA3)is a member of the membrane associated protein family. It has two subtypes of 36 kDa and 33 kDa. Its gene is located on the fourth chromosome of human. ANXA3, widely expressed in human bone marrow, lung, placenta, prostate and thyroid, is closely related to several biological processes such as exoplasmosis, vascular production, fat cell maturity, and white blood cell migration. Studies have found that ANXA3 is abnormally expressed in various diseases including cancer, cardiovascular disease and inflammation. It can regulate multiple signaling pathways such as JNK, NF-κB, PI3K/AKT, and may become a potential drug target for treatment of related diseases. The structure, functions, the link with diseases and related mechanisms of ANXA3 were summarized in this paper, which could provide reference for ANXA3 related research.

Objective To analyze the characteristics of pattern elements and the distribution of patterns of femoral head necrosis, hip osteoarthritis, and hip rheumatoid arthritis, in order to provide a theoretical basis for the "different diseases with the same pattern" of chronic bone diseases. Methods A cross-sectional survey was conducted to select patients with femoral head necrosis Association Research Circulation Osseous Ⅰ-Ⅱ stages, hip osteoarthritis Kellgren & Lawrence Ⅰ-Ⅱ stages, and acute or subacute hip rheumatoid arthritis who visited the Minimally Invasive Arthrology Department, Traumatology Department, and Rheumatology and Immunology Department of Beijing University of Chinese Medicine Third Affiliated Hospital from June 2020 to June 2022. The " case report form - traditional Chinese medicine pattern manifestation scale" previously developed by our team was used to collect the pattern manifestations, which were included into an Excel 2020 spreadsheet to establish a database. SPSS 20.0 software was used for factor analysis and cluster analysis to extract pattern element information, such as disease nature and location, in order to summarize the characteristics of pattern elements, the distribution of patterns, and the similarities and differences of the three kinds of early hip joint diseases.Results A total of 410 patients were included, including 150 patients with femoral head necrosis, 160 patients with hip osteoarthritis, and 100 patients with hip rheumatoid arthritis. The pattern elements of the disease nature of femoral head necrosis include phlegm (dampness), blood stasis, yang deficiency, essence deficiency, and qi deficiency. The pattern types were initially divided into four categories: syndrome of meridian obstruction (43.33%), syndrome of phlegm and blood stasis blocking collaterals (38.00%), syndrome of liver and kidney deficiency (12.00%), and syndrome of kidney essence deficiency (6.67%). The pattern elements of the disease nature of hip osteoarthritis include phlegm (dampness), blood stasis, qi deficiency, essence deficiency, yang deficiency, and cold (dampness). The pattern types were preliminarily divided into five categories: syndrome of spleen and kidney deficiency (37.50%), syndrome of meridian obstruction (26.87%), syndrome of cold and dampness obstruction (18.75%), syndrome of phlegm and blood stasis obstruction (9.38%), and syndrome of liver and kidney deficiency (7.50%). The pattern elements of the disease nature of hip rheumatoid arthritis include phlegm (dampness), blood stasis, qi deficiency, yin and yang deficiency, cold (dampness), and essence deficiency. The pattern types were preliminarily divided into four categories: syndrome of phlegm and blood stasis obstruction (34.00%), syndrome of cold and dampness obstruction (28.00%), syndrome of blood stasis blocking collaterals (23.00%), and syndrome of liver and kidney deficiency (15.00%). Overall, the top five pattern manifestations of the three kinds of hip joint diseases were hip joint pain (96.59%), tenderness (93.90%), fixed pain (87.56%), heavy joints (85.37%), and sourness of lower limbs (75.37%). The pattern elements of the disease nature include phlegm (dampness), blood stasis, qi deficiency, etc. The pattern types were preliminarily divided into five categories: syndrome of phlegm stasis blocking collaterals (33.17%), syndrome of meridian obstruction (31.95%), syndrome of cold dampness obstruction (21.46%), syndrome of liver and kidney deficiency (7.32%), and syndrome of spleen and kidney deficiency (6.10%). There were 21 similar pattern manifestations in the three kinds of early hip joint diseases, with blood stasis and spleen deficiency being the main pattern.Conclusion The common pattern characteristics of three kinds of early hip joint diseases are spleen deficiency and blood stasis. In addition, femoral head necrosis is accompanied with phlegm-dampness pattern, hip osteoarthritis is accompanied with kidney deficiency and phlegm-dampness pattern, hip rheumatoid arthritis is accompanied with kidney deficiency and cold-dampness pattern.
