Objective Regenerating genes express mainly in gastrointestinal tissues and the injured regenerating pancreatic tissues,which can promote the regeneration of pancreatic β cells and other tissue cells.In recent years,researches on Reg family mainly involved the gene structure of various subtypes of Reg,and its role in diabetes,gastrointestinal cancer,inflammation,anti-microbial and the related mechanisms.Among the various subtypes of Reg,regenerating geneⅢ(Reg3) plays a particularly crucial role in these diseases.Therefore,Reg3 is a promising target for the treatment of these diseases.Based on the relationships of Reg3 with a variety of diseases,our group devote to the role of Reg3 [human REG3A,and mouse Reg3γ(Reg3g)] in type 1 diabetes,inflammation-linked pancreatic carcinogenesis,and the immunological changes participated in these processes.Hence,this review will summarize serial studies on Reg3 and the feasibility of it as drug targets.

ObjectiveTo observe the effect of community-based rehabilitation (CBR) on older stroke patients in ability of activities of daily living (ADL).Methods50 older stroke patients were randomly divided into the rehabilitation group and control group. The rehabilitation group was treated with motor function exercise and ADL training, while the control group only took medicine. Two groups were evaluated with Barthel index before and after treatment. ResultsScores of Barthel index on the rehabilitation group were higher than that on the control group after treatment, and there was a significantly difference between two groups (P<0.01). Conclusions CBR has the significant effect on improving ADL in older stroke patients.

Objective To investigate the effect of recipient's pre-transplant triglyceride (TG) abnormalities on early graft function (EGF) after kidney transplantation.Methods According to the inclusion and exclusion criteria,154 identified living-kidney transplant recipients in the 309 Hospital of Chinese PLA from Jan.2011 to Dec.2014 were enrolled in present study,including 124 males and 30 females,and aged of 31.9 ± 8.4 years.The cohort was divided into two groups:TG normal group (0.40＜TG≤1.70mmol/L,n=107) and TG abnormalities group (TG＞l.70mmol/L or require lipid lowering therapy,n=47).The incidences of poor early graft renal function (PEGF),slow graft function (SGF) and delayed graft function (DGF) were compared between the two groups,and then the serum creatinine (Scr) levels were compared among the patients showing immediate graft function (IGF) at 3rd,7th and 30th day after transplantation.The ROC curve was drawn up taking TG as diagnosis index to explore the optimal cut-offvalue for predicting PEGF,SGF and DGF after transplantation.Results Compared with the TG normal group,the TG abnormalities group showed significantly higher incidence of PEGF and DGF (P＜0.05).Among the IGF patients,the TG abnormalities group showed higher Scr level at the 7th and 30th day after transplantation (P＜0.05).The area under ROC curve (AUC) reflected TG levels for PEGF,SGF and DGF were 0.774,0.704 and 0.818,respectively (P＜0.05).The optimal cut-offvalues were all 1.37mmol/L.Conclusions Recipients with abnormal pre-transplant TG level may have worse EGF after renal transplantation.The risk of developing PEGF,S GF and D GF tends to emerge when pre-transplant TG level is higher than 1.37mmol/L.

The GFP(green fluorescence protein)-streptavidin(SA) bi-functional fusion protein was generated and characterized in order to demonstrate novel platform for efficiently and durably modifying the cell surface with SA-tagged bi-functional proteins.The GFP-SA/pET24d construct was generated and expressed in BL21(DE3) host bacteria at the high level.The recombinant protein GFP-SA was purified through the Ni-NTA affinity chromatography,and then refolded.After biotinylation B16 tumor cells were modified with GFP-SA bi-functional fusion protein and then subjected to fluorescent microscopy and FACS analysis.The effect of surface modification on the viability and growth of B16.F10 tumor cells was evaluated by MTT staining.The GFP-SA recombinant fusion protein was expressed in BL21(DE3) at about 20 % of total bacterial proteins.The GFP-SA bi-functional fusion protein exhibited the bi-functionality,i.e.,SA-mediated high-affinity binding to biotinylated cell surfaces and GFP-emitted green fluorescence.The cell surface modification with GFP-SA bi-functional fusion protein did not affect the viability and growth of the modified B16.F10 tumor cells significantly.The GFP-SA bi-functional fusion protein was obtained and could be displayed efficiently on the surface of the biotinylated B16.F10 tumor cells through the specific and tight interaction between streptavidin and biotin,thus can be used as good trace protein and experimental control in the development of surface-modified tumor vaccine.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.

Objective: To determine the clinical, imaging, and histological features, and surgical resection modalities and outcomes of adult sacrococcygeal teratoma (SCT). Methods: Adult patients with histopathologically diagnosed SCT were enrolled in our hospital between August 2010 and August 2018. Each patient’s characteristics and clinical information were reviewed. Results: There were 8 patients in the study (2 males, 6 females) with a median age of 34 years (range, 18–67 years). The time to clinical symptoms was 14 d to 35 years, with a median time of 4 years. Six patients presented with symptoms of sacrococcygeal pain, and four with signs of sacrococcygeal mass and ulceration in the sacrococcygeal region. Six patients were evaluated using a combination of computed tomography (CT) and magnetic resonance imaging (MRI). All patients showed a presacral tumor with heterogeneous intensity on CT images. All patients underwent surgical treatment, including 6 parasacral, 1 transabdominal, and 1 combined anterior-posterior surgery cases. Seven patients were histopathologically diagnosed with benign mature SCT, and have shown no recurrence. One patient had malignant SCT, with recurrence at 84 months after surgery. After a second surgery, the patient had no recurrence within 6 months follow-up after re-resection. Conclusions: Our retrospective study demonstrated: (1) adult SCT is difficult to diagnose because of a lack of typical clinical symptoms and signs; (2) a combination of CT and MRI examination is beneficial for preoperative diagnosis; (3) the choice of surgical approach and surgical resection modality depends on the size, location, and components of the tumor, which can be defined from preoperative CT and MRI evaluation; (4) most adult SCTs are benign; the surgical outcome for the malignant SCT patient was good after complete resection. Even for the patient with recurrent malignant SCT, the surgical outcome was good after re-resection.

BACKGROUND:Recent years, fiber posts and resin cores have been widely used in repairing the endodonticaly treated teeth with satisfactory effect. Erbium:yttrium aluminum garnet (Er:YAG) laser is a new type of water power laser system, which can be used for surface treatment of fiber posts. But studies on the effect of Er:YAG laser surface treatment on the bond strength of fiber posts are rarely reported. OBJECTIVE: To evaluate the effect of surface treatment utilizing Er:YAG laser irradiation with different parameters on the bond strength of fiber posts to root canal dentin. METHODS: Fifty human maxilary central incisors that had similar dimensions were used. After endodontic treatment, removal of the crown and canal preparation, ParaPost FIBER LUX glass fiber posts were cemented into the root canals. According to the method of surface treatment, 50 teeth were randomly divided into: no surface treatment as control group; four groups undergoing surface preparation with Er:YAG laser with four different power settings (150, 250, 350 and 450 mJ at 10 Hz for 60 s at 100-μs pulse duration), named 1.5, 2.5, 3.5, and 4.5 W Er:YAG laser irradiation groups, respectively. RESULTS AND CONCLUSION: The mean bond strength values reduced from the cervical to the apical root canal, and the bond strength of the dental cervix was significantly different from that of middle and apical thirds (P < 0.05), but there was no difference between the middle and apical thirds (P> 0.05). Regardless of the different part of the root slices, the bond strength was highest in the 4.5 W Er:YAG laser irradiation group, showing significant difference from other groups (P < 0.05). These findings indicate that 4.5 W Er:YAG laser irradiation significantly increases the bond strength of the fiber posts to root canal dentin.

Objective To investigate the expression and significance of calcyclin binding protein (CacyBP)in the brain of rat model of traumatic brain injury(TBI).Methods Sixty 60 male SD rats were divided randomly into normal control group (n=10) and TBI group (n=50).The TBI model was created by using lateral head rotation device and subdivided into 6 h,24 h,72 h,7 d and 14 d group (10 rats per group).The expression and distribution of CacyBP in the rat brain was investigated immunohistochemically.The presence of the brown stained particles was considered aspositiveand lack of the stained particles agnegative. Results CacyBP was mainly distributed in the hippocampus,dentate gyrus and cortical neuron cytoplasm.Compared with the high level expression of CacyBP in the normal control group,the expression of CacyBP was decreased to the lowest in the rat brain at 6 h post TBI (P<0.01),became stronger gradually at 24 hours and recovered to normal at day 14,with no statistical difference compared with normal control group (P>0.05). Conclusion The lowest level expression of CacyBP after TBI indicates that CacyBP may play an important role in development of brain injury under effect of difierent mechanisms.
