Clinical study on core decompression in treating osteonecrosis of the femoral head of the necrotic bone-in different site / 中国骨伤

OBJECTIVE@#To analyze the clinical effect of decompression and bone grafting on osteonecrosis of the femoral head(ONFH) at different sites of necrotic lesions.@*METHODS@#A total of 105 patients with ARCOⅡstage ONFH admitted from January 2017 to December 2018 were retrospectively analyzed. There were 71 males and 34 females, with an average age of (55.20±10.98) years old. The mean course of all patients was(15.91±9.85) months. According to Japanese Inveatigation Committee (JIC) classification, all patients were divided into 4 types:17 cases of type A, 26 cases of type B, 33 cases of type C1 and 29 cases of type C2. All four groups were treated with decompression of the pulp core and bone grafting. Visual analogue scale(VAS) and Harris hip joint score were used before and at 3, 6, 12, and 24 months after the operation, and the collapse of the femoral head was observed by X-ray examination within 2 years.@*RESULTS@#All 105 patients were successful on operation without complications, and the mean follow-up duration was (24.45±2.75) months. Harris score showed that there was no statistical difference among four groups before surgery and 3, 6 months after surgery (P>0.05);at 12 and 24 months after surgery, there were significant differences among all groups (P<0.01). There were significant differences in intragroup Harris scores at preoperative and postoperative time points among four groups (P<0.01). VAS showed that there was no statistical difference among four groups before and 3, 6 months after surgery (P>0.05);at 12 and 24 months after surgery, there were significant differences among all groups (P<0.01). There were significant differences in VAS at preoperative and postoperative time points among four groups (P<0.01). None of the patients in four groups had femoral head collapse before and 3, 6 months after surgery. At 12 months after operation, there were 3 cases of femoral head collapse in group C and 4 cases in group C2(P>0.05);At 24 months after operation, 1 case of femoral head collapse occurred in group B, 6 cases in group C1 and 8 cases in group C2(P<0.05).@*CONCLUSION@#Core decompression and bone grafting can improve the effect of ONFH and hip preservation. The effect of hip preservation for ONFH is closely related to the location of the osteonecrosis lesion, so the influence of the location of lesion on the effect of hip preservation should be considered in clinical treatment, so as to make better preoperative hip preservation plan.

Effects of Sinomenine on Expressions of TLR-2, TLR-4 and MyD88 in Cartilage of Rabbit Knee Osteoarthritis Model / 中国中医药信息杂志

Objective To observe the effects of different doses of sinomenine on toll-like receptor (TLR) 2, TLR4 and myeloid differentiation factor 88 (Myd88) in cartilage of rabbit knee osteoarthritis model; To discuss its mechanism of action. Methods Knee osteoarthritis model was established by Hulth method. Experimental rabbits were randomly divided into control group, model group, sinomenine low-, medium-and high-dose groups. Blank group received no processing. Model group, sinomenine low-, medium-and high-dose groups received intra-articular injection of normal saline and sinomenine 0.2 mL (5 mg), 0.35 mL (8.75 mg) and 0.5 mL (12.5 mg) respectively, for 10 times. Real-time fluorescence quantitative PCR and Western blot were used to detect m RNA and protein expressions of TLR2, TLR4 and My D88 in cartilage. Results m RNA and protein expressions of TLR2, TLR4 and MyD88 in model group significantly increased compared with control group (P＜0.01); compared with model group, m RNA and protein expressions of TLR2, TLR4 and My D88 in sinomenine medium-and high-dose groups decreased significantly (P＜0.05, P＜0.01). Conclusion Sinomenine can inhibit the cartilage immune response of rabbit knee osteoarthritis by down-regulating expressions of key molecules in the TLR/My D88 pathway.

Effect of the mixed liquor of danshen and magnesium sulfate injection on IgG and IgM in serum of rabbits with lumbar intervertebral disc herniation / 中国骨伤

<p><b>OBJECTIVE</b>To explore the effect of the mixed liquor of danshen and magnesium sulfate injection on inflammatory reaction caused by autoimmune response of rabbits with lumbar intervertebral disc herniation.</p><p><b>METHODS</b>Sixty rabbits were divided into blank group (10 rabbits), sham operation group (10 rabbits), model group (40 rabbits) according to method of random digits table. Then model group was divided into made group (group A, 10 rabbits), normal saline group (group B, 10 rabbits), aescin natrium group (group C, 10 rabbits) and danshen and magnesium sulfate injection group (group D,10 rabbits). After model success of lumbar intervertebral disc herniation, different drugs were given to rabbits with lumbar intervertebral disc herniation by ear margin vein. The rabbits of the group C,B,D were respectively given aescin natriu (0.5 mg/kg), normal saline (5 ml/kg), danshen and magnesium sulfate injection (2.0 mg/kg). The rabbits of blank group, sham operation group and group A were not given any disposal. The IgG and IgM level in serum of different groups were determined with ELISA method in fourteen day after model success and drugs given.</p><p><b>RESULTS</b>The level of IgG and IgM in the group A was higher than that of blank group and sham operation group (P < 0.05). The level of IgG and IgM in the group D was lower than that of group B,C (P < 0.05).</p><p><b>CONCLUSION</b>The mixed liquor of danshen () and magnesium sulfate injection could inhibit inflammatory reaction caused by autoimmune response of lumbar intervertebral disc herniation,which provides a new alternative for lumbar intervertebral disc herniation.</p>

Effect of Xianlong granules on immunological function in rats of adjuvant arthritis / 中国中药杂志

<p><b>OBJECTIVE</b>To study the effect of Xianlong granules (XLG) on immunological function in the rat of adjuvant arthritis (AA).</p><p><b>METHOD</b>Rats were randomly divided into normal group, AA model group, prednisone group and low, middle and high dose XLG groups, 10 rats in each group. All rats were treated by intragastric administration from the 18 days after arthritis was induced by the complete Freud's adjuvant and the effect of XLG on toes swelling was observed. On the 30th days after modeling, proliferation of the splenic and thymic lymphocytes, and IgG secreted by splenocytes were detected respectively by MTT assay and ELISA.</p><p><b>RESULT</b>Compared with the model group, both the high and middle dose XLG groups had significant therapeutic effects on toes dwelling in the rat of AA (P < 0.05 or P < 0.01); The low, middle and high dose XLG groups strengthened the PHAM-inhibited proliferation of splenic lymphocytes (P < 0.05), and inhibited the PHAM-augmented proliferation of thymic lymphocytes (P < 0.05); XLG did not significantly effect on IgG level secreted by splenocytes in rats of AA.</p><p><b>CONCLUSION</b>XLG can cure toes swelling in rats of AA, which is related with regulation of the abnormal immunlological function.</p>
