Objective To discuss the application value of the Nickel-Titanium patella concentrator(NT-PC) in surgical treatment of patellar fracture.Methods A retrospective analysis was made on clinical data of 32 cases of patellar fracture treated with the NT-PC in this hospital from January 2001 to December 2003.Results Re-examination of radiography at 12 weeks after surgery showed bone union was achieved in all the cases,with a smooth patellofemoral articular surface.The patella was preserved completely in all the comminuted fracture cases.According to the Lu's criteria,excellent and good outcomes were achieved in 26 and 6 cases,respectively,the rate of excellent or good results being 100%.The NT-PC was removed at 4 months ~ 2 years(mean,14 months) postoperatively without complications.Conclusions Application of NT-PC in the treatment of patellar fracture can preserve the comminuted patella completely,facilitate the reduction and fixation of the patellofemoral articular surface,and make early postoperative motions available.It is worthy of being recommended.

OBJECTIVE:To evaluate therapeutic efficacy and safety of chemotherapy combined with Xiaoaiping injection in the treatment of elderly patients with advanced gastric cancer. METHODS:60 elderly patients with advanced gastric cancer were collected from our department during 2012-2014,and then divided into union group and single group with 30 cases in each group. Single group was given irinotecan(CPT-11)150 mg/m2 added into 0.9%Sodium Chloride injection,and union group was addition-ally given Xiaoaiping injection 80 ml,qd,on the basis of single group. A treatment course lasted for 14 days,and both groups re-ceived 4 courses of treatment. The tumor markers,disease single rate,progression-free survival (PFS) and the incidence of ADR were compared between 2 groups. RESULTS:After treatment,the levels of CEA,CA199 and CA242 in 2 groups were significant-ly lower than before;the union group was significantly lower than the single group,with statistical significance(P<0.05). The dis-ease single rate of union group was 70.00%,which was significantly higher than that of single group (33.33%). PFS of union group was(11.23±2.17)months,which was significantly longer that of single group [(9.36±0.84)months],with statistical signif-icance(P<0.05). The incidence of leucopenia,alanine aminotransferase elevation,diarrhea,stomatitis and hand-foot syndrome in union group was significantly lower than in single group,with statistical significance(P<0.05). CONCLUSIONS:Xiaoaiping in-jection combined with irinotecan chemotherapy for advanced gastric cancer has obvious effect with a low incidence of ADR.

Altogether 202 cases of cervical spondylosis were treated with traction first,followed by needling such points as Jiaji (Ex-B 2), Dazhui (GV 14), Fengfu (GV 16), Fengchi(GB 20), Baihui (GV 20), Yuzhen (BL 9), Houxi (SI 3) and Hegu (LI 4) with combination of point injection on Jiaji (Ex-B 2) points and TDP irradiation on the affected region. After three courses of treatment, the total effective rate reached 98.5%, among which those with types of cervical, nerve-root and vertebral artery took 1-2 courses, while those with types of spinal cord and sympathetic nerve took 2-3 courses.

Low-density lipoprotein receptor-related protein-1 (LRP-1) is a transmembrane receptor protein locatedon the plasma membrane of the cells and involved in receptor-mediated endocytosis.LRP-1 binds to distinct ligandsthat are structurally and functionally unrelated, which makes it not only mediates endocytosis, but also regulates cell surfaceproteolytic activity and specific intracellular signaling pathways related to multiple links in the process of developmentof atherosclerosis.Moreover, LRP-1 plays an important role in maintaining vascular stability.This review focuses on theprogress in LRP-1-regulated vascular integrity, and provides new insights to the target of the blood vessel diseases.

Objective To explore the role of Th17/IL-17 in the pathogenesis of asthma in children.Methods Thirty asthma children (asthma group) and 20 healthy volunteers (control group) were selected as our subjects.Percentage of Th17 cell in peripheral blood mononuclear cell (PBMC) of asthma children was detected by flow cytometry,the level of IL-17 and IgE in plasma were examined by enzyme linked immunosorbent assay.Results Proportion of Th17 cells in PBMC of children in asthma group was (1.83 ± 1.01) ％,significantly higher than that in control group ((1.02 ± 0.49) ％ ; t =3.896 ; P ＜ 0.01).The IL-17 level in control group was (19.11 ± 3.23) ng/L,significant lower than that in asthma group ((34.23 ± 4.88) ng/L;t =6.261 ;P ＜ 0.01)).The Ig E level in asthma group was (399.4 ± 45.1) ng/L,significantly higher than in control group((58.2 ± 19.7) ng/L;t =7.244,P ＜0.01).The level of IL-17 in plasma had a postive relationship with the proportion of Th17 cells(r =0.882,P ＜0.01),but not relationship was seen with the level of IgE (r =0.375,P ＜ 0.05).Conclusion Th1 7 cell is associated with asthma development of children,and the reason may due to probably aggravating asthma condition through increasing inflammation secreting IL-17.

BACKGROUND:Brain-derived neurotrophic factor has been detected in bone and tooth, and its role in development and metabolism of bone and tooth tissue as wel as its clinical application has become a hot spot. OBJECTIVE: To summarize and analyze the effect and mechanism of brain-derived neurotrophic factor in development and metabolism of bone and tooth tissues. METHODS: Papers addressing the effect of brain-derived neurotrophic factor in bone and tooth tissue were retrieved by computer in Wanfang and PubMed databases with the key words of “brain-derived neurotrophic factor, TrkB, p75NTR, signaling, bone, tooth, osteoblasts, osteoclasts” in Chinese and English, respectively. A total of 53 papers were included for review. RESULTS AND CONCLUSION:Brain-derived neurotrophic factor can be detected in various tissuesin vivo, and can regulate cel survival and apoptosis through binding its two receptors. Brain-derived neurotrophic factor in bone and tooth tissue can bind to target cels, induce or inhibit cel proliferation and differentiation, indicating that brain-derived neurotrophic factor is closely linked to bone and tooth tissue, and may play a role in growth and reconstruction of bone and tooth. Its mechanism of action is mainly through binding to TrkB receptor, to activate downstream pathways and affect differentiation and proliferation of mesenchymal stem cels, osteoblasts, chondrocytes, and periodontal ligament cels. Interaction between p75NTR receptor and TrkB receptor may be one of the factors affecting cel differentiation or proliferation.
