BACKGROUND:Compared with organic fluorescent dyes and fluorescent proteins, rare earth nanomaterials have higher sensitivity, better optical stability, and lower cytotoxicity. OBJECTIVE: To investigate thein vitro cytocompatibility of (Y0.95Eu0.05)2O3 METHODS:(Y rare earth nanomaterial and the effect of amine functionalization on the material cytocompatibility. 0.95Eu0.05)2O3 nanomaterials were synthesized using sol-gel method, and underwent amine functionalization. Amine-functionalized samples (10, 25, 50, 100, 200 mg/L) and non-amine-functionalized (Y0.95Eu0.05)2O3 rare earth nanomaterial suspensions were co-cultured with vascular smooth muscle cels of Sprague-Dawley rats for 3 days. Cel proliferation was detected using Cel Counting Kit-8 assay. 100 mg/L amine-functionalized samples and non-amine-functionalized (Y0.95Eu0.05)2O3 rare earth nanomaterial suspensions were co-cultured with L929 cels for 48 hours. Cel apoptosis was observed using fluorescence staining. RESULTS AND CONCLUSION:With increased mass concentration of material suspension, survival rate of vascular smooth muscle cels was gradualy reduced. At the mass concentration of 10, 25, 50 mg/L, cel survival rate was significantly higher in the amine-functionalized group than in the non-amine-functionalized group (P < 0.05). When the mass concentration of materials reached 200 mg/L, the cel survival rate decreased to 76% in the non-amine-functionalized group, but it was stil above 80% in the amine-functionalized group, showing significant differences between the two groups (P < 0.05). The growth of L929 cels was good and the number of apoptotic cels was less in the amine-functionalized group. Cels were sparse and the number of cel apoptosis was more in the non-amine-functionalized group, showing slight cytotoxicity. These data verified that amine-functionalization can improve cytocompatibility of (Y0.95Eu0.05)2O3 rare earth nanomaterial.

Objective To evaluate the clinical significance of the serum β2-microglobulin (β 2-MG) and lactic dehydrogenase (LDH) in multiple myeloma (MM) patients.Methods The serum levels of β2-MG and LDH in 63 MM patients (MM group) and 20 healthy person (control group) were measured by biochemical assay.Results The serum levels of β 2-MG and LDH in MM group were higher than those in control group[(3.81 ± 0.62) mg/L vs.(2.43 ± 0.91) mg/L and (296.4 ± 34.7) U/L vs.(145.5 ±17.8) U/L,P < 0.05].Furthermore,the serum levels of β 2-MG and LDH increased gradually with MM clinical staging (P <0.05).After VAD chemotherapy,the serum levels of β 2-MG and LDH in clinical response MM patients(54 cases) were significantly decreased [(2.51 ± 1.36) mg/L vs.(3.57 ± 0.82) mg/L and (159.1 ± 35.2) U/L vs.(285.3 ± 87.6) U/L,P < 0.05],while those in no response patients (9 cases)were unchanged (P> 0.05).Conclusion The serum levels of β 2-MG and LDH can be taken as a clinical index to classify the clinical phase,prognosis and effectiveness of chemotherapy in MM patients.

Purpose To investigate the expression of TET2 and DNMT3A in patients with peripheral T cell lymphoma (PTCL) and the relationship to immunophenotypes of PTCL.Methods Using a panel of immunohistochemical markers (CD3,CD4,CD10,BCL-6,CXCL-13,CD30,ALK),all cases of PTCLs were further divided into four groups,including angioimmunoblastic T cell lymphoma (AITL),peripheral T cell lymphoma,not otherwise specified (PTCL-NOS),anaplastic lymphoma kinase negative anaplastic large cell lymphoma (ALK-ALCL) and anaplastic lymphoma kinase positive anaplastic large cell lymphoma (ALK + ALCL).The expression of TET2 and DNMT3A in 89 cases of PTCL was detected by immunohistochemical analysis.Results 89 cases were divide into four subtypes,AITL (36/89),PTCL-NOS (26/89),ALKALCL (18/89),and ALK + ALCL (9/89).Immunohistochemistry staining revealed higher cytoplasmic expression of TET2 and DNMT3A in AITL than that of in PTCL-NOS and ALCL (P < 0.05).And the nuclear expression of DNMT3A in patients with AITL was higher than that of PTCL-NOS and ALCL (P < 0.05).The cytoplasmic expression of TET2 was positively related with both cytoplasmic and nuclear expression of DNMT3A in patients with AITL (P < 0.05).Conclusion TET2 combined with DNMT3A could be used as markers in AITL diagnosis,which could provide new strategy for AITL diagnosis.

Objective:To discuss the influence of bifid triple viable enteric-coated capsules on liver function and inflammatory fac-tor in the patients with non-alcoholic steatohepatitis ( NASH) . Methods:Totally 70 cases of patients with NASH were selected and di-vided into the control group and the observation group at random. The patients in the two groups were all given routine hepatoprotective therapy. The patients in the observation group were additionally given 420mg bifid triple viable enteric-coated capsules, three times a day for 4 weeks. Except for bifid triple viable enteric-coated capsules, the patients in the control group were given the same medical treatment as that in the observation group. The changes of liver function index, serum high sensitivity C reaction protein ( hs-CRP) , IL-6 and IL-8 levels in the two groups before and after the medical treatment were observed and the security was compared. Results:After the 4-week medical treatment, ALT, GGT, serum hs-CRP, IL-6 and IL-8 levels in the two groups were obviously declined than those before the treatment (P<0. 05 or P<0. 01), and the declining rate in the observation group was much higher than that in the control group (P<0. 05). Totally 6 and 4 cases of adverse drug reaction (ADR) respectively appeared in the observation group and the control group during the medical treatment with mild symptom, and the difference was without statistical significance (P>0. 05). Conclusion:Bifid triple viable enteric-coated capsules in the treatment of NASH can obviously reduce the serum hs-CRP, IL-6 and IL-8 levels, inhibit the intrahepatic inflammation and immunologic injury, and improve the liver function index with high security.

Objective:To establish the quality standard for Yunüjian granules. Methods:Rehmannia glutinosa, rhizoma anemar-rhenae and achyranthes in the granules were identified by TLC. The HPLC method was adopted. A SunfireTM C18 column (250 mm × 4. 6 mm, 5 μm) was used with the mobile phase consisting of acetonitrile-0. 1% acetic acid solution(16∶84) at the column tempera-ture of 30 ℃. The flow rate was 1. 0 ml·min-1 ,the detection wavelength was 334nm, and the imjection volume was 10 μl. Results:The TLC spots of verbascoside, and sarsasapogenin in rhizoma anemarrhenae and cyasterone in achyranthes were quite clear with good seperation. The linear range of verbascoside was within the range of 0.163-0.612 μg(r=0.999 9), and the average recovery was 101. 3%(RSD=2. 7%,n=6). Conclusion:The method is simple, reliable and accurate, and can be applied in the quality control of Ynnüjian granules.

Objective To investigate the relationship between pelvic asymmetry and Crowe classification of unilateral developmental dysplasia of the hip in adults. Methods According to the inclusion criteria, 100 cases of unilateral DDH in adults were collected, including 78 females and 22 males, with an average age of 56.3 years old (range, 21-79 years). In terms of Crowe classification, there were 30 cases of Crowe typeⅠ, 24 cases of Crowe typeⅡ, 23 cases of Crowe typeⅢ, and 23 cases of CroweⅣ. The normal?side and affected?side pelvic vertical height (the distance from the highest point of the ischial tuberosity to the iliac crest peak) were measured via the radiogram of anteroposterior pelvis. Furthermore, we compared the affected?side pelvic vertical height with the normal?side and analyzed the relationship between Crowe classification and the difference in pelvic verti?cal height. Results The average pelvic vertical height was 23.38±1.46 cm in the normal?side and 22.41±1.38 cm in the affected?side. The average D?value of pelvic vertical height between two sides is 0.98 ± 0.76 cm. From Crowe typeⅠto Ⅳ, the average heights of the normal?side were 22.89±1.09 cm, 23.23±2.07 cm, 23.75±1.16 cm, 23.79±1.22 cm, while those of the affected?side were 22.70 ± 0.98 cm, 22.41 ± 1.98 cm, 22.47 ± 1.12 cm and 21.92 ± 1.32 cm. The average D?values in each group were 0.19 ± 0.37 cm, 0.82±0.43 cm, 1.28±0.32 cm, 1.87±0.59 cm. The differences between the normal?side and the affected?side in each type were statistically significant. The average D?value increased significantly with Crowe type increased, and there was a positive correla?tion between the D?value of bilateral pelvic vertical height and the degree of hip dislocation. Conclusion The pelvic asymmetry does exist in adult patients with unilateral developmental dysplasia of the hip. Moreover, the asymmetry has positive correlation with the degree of hip dislocation.
