The treatment and signaling pathway regulation effects of kidney- tonifying traditional Chinese medicine on osteoporosis have been widely studied, but without a systematic summary currently. This review comprehensively collected and analyzed the traditional Chinese medicine on the treatment and signaling pathway regulation of osteoporosis in recent ten years, such as Epimedium, Drynariae Rhizoma, Cnidium, Eucommia, Psoralen and Dipsacus. Based on the existing findings, we concluded the following conclusions: (1) kidney-tonifying traditional Chinese medicine treats osteoporosis mainly through BMP-Smads, Wnt/β-catenin, MAPK, PI3K/AKT signaling pathway to promote osteoblast bone formation and through OPG/RANKL/RANK, estrogen, CTSK signaling pathway to inhibit osteo?clasts of bone resorption. ① Epimedium, Drynariae Rhizoma, Cnidium and Psoralen up-regulate the key proteins and genes of BMP-Smads and Wnt/β-catenin signaling pathways to promote bone formation.② Epimedium, Drynariae Rhizoma, Cnidium, Eucommia, Psoralen, Dipsacusinhibit the bone resorption by mediating the OPG/RANKL/RANK signaling pathway. (2) Kidney-tonifying traditional Chinese medicine prevent and treat osteoporosis through a variety of ways: Icariin, Naringin, Osthol, Psoralen can regulate BMP-Smads, Wnt/β-catenin signaling pathway to promote bone formation, but also activate OPG/RANKL/RANK, CTSK and other signaling pathway to inhibit bone resorption. (3) The crosstalk of the signaling pathways and the animal experiments of the traditional Chinese medicine on the prevention and treatment of osteoporosis as well as their multi-target mechanism and comprehensive regulation need further clarification.

Objective To identify mutations site and clinical characteristics of a familial hypercholesterolemia(FH) proband diagnosed clinically through DNA sequencing and family analysis in the proband and his family members of 3 generations.Methods Blood samples and clinical data of the kindred of total 29 from 3 generations members were collected.Proband had a physical examination electrocar-diogrom and vascular ultrasound.The proband and his family members took routine clinical exams,and genomic DNA was isolated.The promoter region and the 18 exons of low density liporotein receptor(LDLR) gene were screened by Touch down polymerase chain reaction -single strand conformation polymorphism(PCR-SSCP) and DNA sequencing.The result of sequencing were matched gene sequence published in the BLAST database.Results 1.Increased intima-media thickness and plaque were detected in the common carotid artery,right subclavian artery of the proband.Aortic valve regurgitation was found by echocardiography.2.No mutation R3500Q of ApoB100 was observed.3.Two heterozygous mutations in exon 10 and 13 of LDLR gene (W462X and A606T) were identified.The proband and 5 members of paternal relatives showed W462X heterozygosis mutation in exon 10 of LDLR gene which introduced the change from tryptophone to a new stop codon.The proband's mother and grandmother harboured A606T heterozygous mutation in exon 13 of LDLR gene due to a single base pair substitution of G for A in the codon for residue 1 879.Conclusions Disease causing mutations of proband are W462X and A606T compound heterozygosis mutation in exon 10 and 13 of LDLR gene inherited from mother and father.Proband shows homozyous phenotype though the genotype analysis indicates heterozygous mutations.

OBJECTIVETo discuss arthroscopic technique of single Kirschner wire and suture avoiding epiphyseal line fixation for tibial intercondylar eminence fracture and its clinical results.

METHODSFrom May 2008 to December 2012, 21 patients (13 males, 8 females, ranging in age from 6 to 14 years old) with tibial intercondylar eminence fracture were treated arthroscopically with single Kirschner wire and suture avoiding epiphyseal line fixation technique. According to Meyers and McKeever classification, 7 patients were type II, 10 patients were type III, and 4 patients were type IV. Active rehabilitation began at one week after operation. The patients were followed up for 10 to 30 months. X-ray films were taken to evaluate fracture healing at 1, 3, 6 months after operation; range of motion, the anterior drawer test, the lachman test and the Lysholm knee score were used to evaluate clinical effects.

RESULTSAll fractures were healed without displacement at 6 weeks after operation. Anterior drawer test and the lachman test were both negative in all patients at 3 months after operation. Lysholm knee score was 95.5 ±2.5 at 6 months after operation, and postoperative X-ray film did not find epiphyseal line broadening or narrowing.

CONCLUSIONArthroscopic treatment for tibial eminence intercondylar fracture with single Kirschner wire and 8-shaped suture avoiding epiphyseal line fixation technique has many advantages, such as firm fixation,early mobilization, less invasive, less injury of physis and satisfactory effect.

Objective: To evaluate the effect of NGX6 with 5-Fu on the apoptosis of colon cancer cells. Methods: The NGX6-transfected HT-29 cell line with 5-Fu was used in the test group. HT-29 cell line with 5-Fu and PDTC was used in the control group. The expression of NF-κB was detected by EMSA. The proliferation of HT-29 cell line was assayed by MTT. The effect of NGX6 on the apoptosis was detected by FCM. HT-29 cells were double-stained by PI/Annexin-V and AO/EB and observed by fluorescence microscopy. Results: The expression of NF-κB was inhibited in NGX6 transfected colon carcinoma cell group and in colon carcino-ma cell group treated with PDTC. Treatment with the chemopreventive compounds 5-Fu and PDTC resulted in different responses in the effects of anti-proliferation and induced apoptosis of colon carcinoma cells. There was no significant difference in apoptosis between NGX6-transfected HT-29 call line with 5-Fu and the cells in the control group. NGX6 gene enhanced the effect of 5-Fu on the proliferation and apoptosis of colon carcino-ma cells. Conclusion: NGX6 gene can induce apoptosis and inhibit the proliferation of colon carcinoma cells. NGX6 gene can enhance the effect of 5-Fu on the proliferation and apoptosis of colon carcinoma cells through NF-κB pathway.

OBJECTIVETo study the mechanism of Bushen Qiangdu Recipe (BQR) for regulating osteoprotegerin receptor activator for nuclear factor kappa B ligand (OPG/RANKL) pathway in ankylosing spondylitis (AS).

METHODSThirty active AS inpatients or outpatients were recruited from Department of CM Rheumatology, China-Japan Friendship Hospital from January to May 2009. All patients were treated with BQR for 3 successive months, one dose daily, once in the morning and once in the evening. Besides, 30 healthy volunteers were recruited. The serum of patients and volunteers were collected. The osteoblast cell lines hFOB1. 19 were divided into 3 groups: the pre-treatment group, the post-treatment group, and the healthy volunteer group (as the control group). All cell lines were cultured by corresponding culture medium containing each serum. The supernatant from osteoblast cell lines was collected. The protein content of OPG/RANKL was detected using ELISA, and the protein expression of OPG/RANKL was detected using RT-PCR.

RESULTSCompared with the control group, the OPG content, the mRNA and protein expressions of OPG, and the mRNA and protein expressions of OPG/RANKL all decreased, while the mRNA expression of RANKL increased in the pre-treatment group, showing statistical difference (P<0.05, P<0.01). Compared with the pre-treatment group, the OPG content, the mRNA and protein expressions of OPG significantly increased, and the mRNA and protein expressions of OPG/RANKL increased, while the mRNA expression of RANKL decreased in the post-treatment group, showing statistical difference (P<0.05, P<0.01).

CONCLUSIONSAS patients' serum could directly inhibit the expression of OPG in osteoblasts, promote the expression of RANKL, and down-regulate the OPG/RANKL ratio. BQR containing serum might promote the osteogenesis and inhibit the bone resorption possibly through directly up-regulating the OPG/RANKL ratio in osteoblast, thus inhibiting the differentiation and function of osteoclast.
