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.

In recent years, there has been a growing emphasis on use of human adipose-derived stem cells (hADSCs) for cartilage tissue engineering owing to their ability to differentiate into chondrocytes, which is mainly induced by growth factors (GFs). In general, GFs for chondrogenic induction come from the transforming growth factor beta (TGF-beta) superfamily. To date, the most commonly used GFs for chondrogenes is TGF-beta1/3. However, the response of hADSCs to GFs may differ significantly from that of human bone marrow stem cells (hBMSCs). It has been reported that bone morphogenetic protein-6 (BMP-6) treatment induced TGF-beta receptor-I expression of hADSCs. It seems that these two cell populations varied strongly in their potency to undergo chondrogenesis in the same medium conditions. Here, we provide a concise review on various GFs used in chondrogenic differentiation of hADSCs in vitro.

Objective To study three single nucleotide polymorphisms (SNP), SNP-43, -19 and - 63 of calpain-10 (CAPN10) gene in pregnant women with glucose metabolism disorders and their relationship with the risk of these disorders. Methods Totally, 270 pregnant women including 156 with an abnormal oral glucose tolerance test (study group) and 114 healthy controls were selected among those delivered at the Department of Obstetrics and Gynecology, Peking University First Hospital from Jan. 2005 to Dec. 2006. The SNP of CAPN10 gene at posifons 43, 19, and 63 were analyzed by primer-introduced restriction analysis-polymerase chain reaction (PIRA-PCR). Results (1) The frequencies CAPN10 SNP-19 2R/2R genotype (26.9% ,42/156) and 2R allele (48.9%, 152/312 ) were higher than those in controls (12.3% ,14/114 and 36.8% ,84/228, respectively; P=0.012, 0.006). (2) Stratified analysis according to family history of diabetes mellitus showed the proportion of the CAPN10 SNP-19 2R/2R+2R/3R genotypes (83% ,47/57) in the study group were significantly higher than that of control group (52%,11/21 ; P=0.009), and the proportion of SNP-63 T/T + T/C genotypes(47% ,27/57) in study group were significantly higher than that of control group (14%, 3/21 ; P=0.026) among those with positive family history. (3) The combined effect of CAPN10 SNP-43, -19 and -63 on glucose metabolism disorders was analyzed by comparing with the other haplotypes and showed that the haplotype 121 distribution in study group was significantly higher than those in controls(P=0.036), and 221 haplotype was significantly lower than controls (P=0.042). Conclusions (1) CAPN10 SNP-19 is associated with glucose metabolism disorders in pregnant women. And 2R allele might be the risk factor. CAPN10 SNP-19 2R/2R +2R/3R and SNP-63 T/T + T/C genotypes might increase the risk of glucose metabolism disorders in women with positive family history. Haplotype 121 might increase the risk of glucose metabolism disorders in pregnant women and 221 be a protective factor.

Inflammatory bowel disease( IBD),comprising Crohn’s disease( CD)and ulcerative colitis( UC),is a chronic intestinal inflammatory disease and its etiology has not yet been clarified. Studies showed that intestinal microbiota disorder is closely associated with the development and progression of IBD. Currently,fecal microbiota transplantation (FMT)is considered as a special organ transplantation and used in treatment of IBD,Clostridium difficile infection, irritable bowel syndrome,metabolic syndrome,etc. This article reviewed the relationship between FMT and IBD.

Objective To explore the effect of methylprednisolone combined with interferon in the treatment patients with relapse remitting multiple sclerosis.Methods 90 patients with relapse remitting multiple sclerosis were randomly divided into experimental group and treatment group.The experimental group during the acute stage with methylprednisolone pulse therapy,remission with interferon β (IFN-β) treatment; the control group only in the acute phase with methylprednisolone pulse therapy.Results The total effective rate of methylprednisolone pulse therapy in the acute stage was 98.9％.Experimental group during the treatment with IFN-β1α,relapse rate was 30.2％ ;patients in the control group were followed up for two years,the recurrence rate was 53.3％.Experimental group and control group was significantly different ( P ＜ 0.05 ),the experimental group was significantly lower than the control group.Conclusion For relapsing-remitting MS,using MPPT could relieve acute symptom in the acute stage,and in remission using of IFN-β1α relapse prevention was a good choice for clinicians.

Lysyl oxidase-like protein 2 (LOXL2) is one of the lysyl oxidases (LOX) families.At present,most of scholars consider that LOXL2 is a neoplasm metastasis gene,whereas some others belleve that LOXL2 is a neoplasm suppressor gene.Studies found that LOXL2 gene combined with other oncogenes promotes neoplasm invasion,metastasis and indicates a poor prognosis.Related researches provide new ideas for judging tumor metastasis and prognosis and looking for new targets for cancer therapy.
