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.

Amounts of researches show that EPO is characterized with neurotrophic and neuroprotective manner, especially in brain stroke, which attracts a large numbers of researchers to study it. With the accumulating researches on its neuroprotection, many related mechanisms were revealed, such as antioxidant, anti-apoptosis, angiogenesis, anti-inflammatory, which suggests a multiple targets role of EPO on brain stroke. However, because of the high risk of thromboembolism in clinical administration of rhEPO and its analogs, the herbs are potential to be a replacer for its less side effects. Many researchers suggested that a larger of herbs were founded having the action of increasing the endogenous EPO in the model of anemia and cerebral ischemia. At the same time, there herbs were also proved that they had the action of against cerebral ischemia while some without considering the role of EPO in the reports. Considering of the action of promoting EPO of these herbs and the neural protection of EPO, this essay mainly summarizes the studies of herbs promoting EPO in the cerebral ischemia and discusses the mechanism of regulating the EPO of these herbs, for the aim of finding the potential drugs against cerebral ischemia.

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 explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients to guide individualized inmunosuppressive therapy. Methods From Jan. 2008 to Jan. 2010, 30 recipients received living related kidney transplantation were successively and divided into 2 groups according to the strategies of the correction of the dosage of immunosuppressant, 15 in each group. The strategy of immunosuppressive therapy in both groups was Tac + MMF + Pred. The correction of the dosage of immunosuppressant in experimental group was conducted by recipient lymphocyte reaction with donor DC (LR) combined with Tac and MPA blood concentration monitoring. Only blood concentration monitoring of drugs was applied in control group. Examinations of liver and renal function, blood and urine routine as well as blood sugar were done monthly for 1 year. ResultsDuring the follow-up period, the rate of acute rejection in experimental group and control group was 13. 3 ％ and 46. 7 ％ respectively (P＜0. 05) ;the rate of infection in experimental group and control group was 6. 7％ and 40. 0％ (P＜0. 05)respectively; the adverse reaction rate in experimental group and control group was 13. 3％ and 46. 7％(P＜0. 05). There was no significant difference in the serum creatinine level between the two groups at each observation point. ConclusionThe application of combined recipient LR with donor DC and blood concentration monitoring of drugs in individualized irnmunosuppressive therapy is more comprehensive and accurate.

Microscopic identification and NIRS methods were applied to identify Clematidis Radix et Rhizoma of two different origins. The results showed that both methods could identify the samples. NIRS could identify the two samples nondestructively, and provides a basis for establishment of a standard herbs radix clematidis NIRS fingerprint in the future.

Objective To explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients. Methods Donor bone marrow monocytes (BMMCs) were isolated and cryopreserved in liquid nitrogen before kidney transplantation. At 0 day, 1month,3 month, 6 month and 9 month post-operation, CD34+ cells which were isolated from frozen BMMCs and cultured into DCs as well as the peripheral blood lymphocytes (PBLs) of donors were used as the stimulating cells to the PBLs of recipients and healthy volunteers. The number of viable DCs from frozen- and room temperature-preserved BMMCs was counted and the reactions of recipients'and healthy volunteers' lymphocytes to DCs and donor PBLs were measured. Results 6. 8 × 107BMMCs were isolated from each 10 ml of donor bone marrow on average while (4. 10 ± 0. 58) × 105CD34+ cells were isolated by magnetic active cell sorting (MACS). There was no significant difference in the isolating rate of recovered CD34+ cells at each observation point postoperatively. The percentage of viable BMMCs and CD34+ was decreased significantly at 1 month after surgery, then, decreased slowly and progressively. The decreasing rate of BMMCs was higher than CD34+. The rate of viable DCs was maintained stable (93. 2%-94. 8% ) in each group. The reactions of recipients' and healthy volunteers' lymphocytes to DCs were stronger than those to donor PBLs (P＜0. 05). The reactions of healthy volunteers' lymphocytes to DCs were maintained stable while those of recipients' were fluctuating. Conclusion Bone marrow-derived DCs are superior to PBLs in mediating long-term lymphocyte reaction after kidney transplantation due to their stable viability and stimulating ability to lymphocytes. Only once collection of a small quality of bone marrow of donors is needed to meet the demand of immune monitoring at any time after transplantation.
