ObjectiveTo evaluate the efficacy and safety of Rongjin Tongbi decoction on sciatica caused by lumbar intervertebral disc herniation with liver and kidney deficiency type based on a randomized controlled study. MethodFrom January 2019 to July 2022， 90 patients in the department of Traditional Chinese medicine（TCM） of Beijing Jishuitan Hospital who met the inclusion criteria were selected and divided into two groups according to the random number table， with 45 patients in each group. During the study， 19 cases dropped out， with 41 cases included in the final observation group and 30 cases in the control group. The observation group was given Rongjin Tongbi decoction orally， and the control group was given Loxoprofen Sodium Tablets orally for 28 days. The differences in the visual analog scale （VAS） scores， the Japanese Orthopaedic Association （JOA） scores， activities of daily living （ADL） assessments， TCM clinical symptoms， subjective symptoms， and clinical signs scores between two groups before and after treatment were observed. Liver and kidney functions and gastrointestinal adverse reactions were detected for safety evaluation. ResultBefore treatment， there was no statistically significant difference in scores between the observation group and the control group. After treatment， the absolute values of the differences in VAS and ADL scores in the observation group were higher than those in the control group （P<0.05）. There was no statistically significant difference in the absolute value of the difference in JOA scores between two groups. The absolute value of the difference in TCM clinical symptom scores in the observation group was higher than that in the control group （P<0.01）. There was no statistically significant difference in the absolute values of the differences in subjective symptom and clinical sign scores between two groups. The levels of liver and kidney function indicators in both groups before and after the experiment were normal， and there was no significant difference in gastrointestinal reactions. ConclusionRongjin Tongbi decoction can significantly improve the symptoms of sciatica patients caused by lumbar intervertebral disc herniation with liver and kidney deficiency type. After treatment， the patients exhibited significant improvements in pain， activity and other aspects， and it is proven to be safe and reliable， which is conducive to the recovery of physical function.

Osteoporosis is an important cause of bone weakness and susceptibility to fractures. Anti-osteoporosis drugs of Western medicine cannot reverse its progression， and can only reduce the loss of bone density； long-term use of them is accompanied by certain adverse reactions. Traditional Chinese medicine focuses on syndrome differentiation and holistic approach， which can make up for the shortcomings of Western medicine’s treatment. The mammalian target of rapamycin （mTOR） signaling pathway is involved in the growth， proliferation， and differentiation of bone cells， and is closely related to the occurrence and development of osteoporosis. In recent years， various traditional Chinese medicine monomers （such as flavonoids， polysaccharides， alkaloids， etc.） and traditional Chinese medicine formulas （such as Bushen huoxue decoction， Liuwei dihuang pills， Erzhi pills， etc.） have been proven to promote bone formation， inhibit bone resorption， enhance bone cell autophagy， and delay the progression of osteoporosis by regulating the mTOR signaling pathway. Therefore， the article summarizes the traditional Chinese medicine monomer and formula that intervene in the mTOR signaling pathway for the treatment of osteoporosis， in order to provide medication ideas for the traditional Chinese medicine treatment of osteoporosis.

To evaluate the immunities of biodegradable microsphere as a release delivery system for DNA vaccine against Infectious Bursal Disease Virus, in our study, silk fibroin/chitosan microsphere adjuvant was prepared with a precipitation/coacervation method. Both glutaraldehyde and Na2SO4 solution were used in cross-linking. No immune chicken were intramuscularly inoculated at 14 day-old and boosted 2 weeks later. The results show that glutaraldehyde destroyed the DNA activity of the vaccine whereas Na2SO4 solution did not. Factors of the chitosan concentration 0.5% (pH 5.0), silk fibroin concentration 0.6%, plasmid DNA (500 microg/mL) dissolved in 2% Na2SO4 solution were optimized to produce microsphere, with a loading capacity of 89.14%. The average particle size of SF-CS/pCI-VP2/4/3 microsphere is 1.98 microm, and it can protect the loading DNA vaccine from DNase I digestion. Data from anti IBDV ELISA antibodies in the serum show that immunization activity of the microsphere groups were generally higher than plasmid vaccine group (P < 0.05), and the SF/CS compound microspheres group was better than that of sole CS microsphere group. The developed SF/CS microspheres are a very promising vaccine delivery system.

BACKGROUND:The outcomes of SL-Plus? stem in primary total hip arthroplasty have been proved good, but whether SLR-Plus? revision stem can obtain a good outcome in revision hip arthroplasty needs more studies. OBJECTIVE:To observe the clinical results of revision hip arthroplasty with Zweymül er SLR-plus ? stem. METHODS:Revision hip arthroplasty of 41 hips in 39 patients was performed from November 1997 to May 2013 using SLR-plus ? stem. There were 26 hips (male) and 15 hips (female). They were at the age of 34-73 years old, 53 on average. In the 41 hips, 36 cemented and 5 uncemented femoral prostheses were used. Prosthetic changes on radiographs were observed. In accordance with Brooker classification, heterotopic ossification was classified to record the region and incidence of heterotopic ossification. Hip joint function was evaluated using Harris Hip Score, and survival rate of the prosthesis was analyzed. RESULTS AND CONCLUSION:A total of 31 patients (33 hips) were fol owed up for 1 to 16 years. The mean preoperative Harris hip score of 34 (range, 13-64) points improved to 85 (range, 55-94) points at the time of final fol ow-up. 32 hips (97%) had an excellent result. A 1 mm width radiolucent line was found in 1 femoral component without any symptom. Osteolysis and migration were seen in 1 hip, which needed re-revision. Heterotopic ossification developed in 9 hips, including 2 hips of Brooker grade 1, 4 hips of grade 2 and 3 hips of grade 3. No re-infection was found. Kaplan-Meier survivorship was 92%with radiographic loosening as the end point. Results demonstrated that the SLR-Plus? stem has sufficient immediate and long-term stability, which is reliable for patients undergoing hip revision surgery.
