AIM:To investigate the regulatory effects of phosphatylinositol 3-kinase/protein kinase B (PI3K/PKB) signaling pathway on the expression of osteopontin ( OPN) in transforming growth factor-β1 ( TGF-β1 )-induced hu-man hepatic stellate cells .METHODS:Human hepatic stellate cell line LX-2 was cultured in DMEM and stimulated by TGF-β1 at the final concentration of 2.5, 5, 10 and 20 μg/L for 24 h or at final concentration of 10 μg/L for 12 h, 24 h and 48 h.LX-2 cells were pretreated with wortmannin , a specific inhibitor of PI3K/PKB signaling pathway , at final con-centration of 0.1 μmol/L for 1 h, followed by incubation with TGF-β1 at final concentration of 10μg/L for 24 h.The cells were collected.The expression of OPN was detected by real-time PCR and Western blotting .RESULTS: In LX-2 cells, the expression of OPN was apparently elevated when incubated with TGF-β1 .With the increase in TGF-β1 concentration or the extension of incubation hours , the expression of OPN was increased gradually in a dose-and time-dependent manner with certain limits.LX-2 cells pretreated with wortmannin and incubated with TGF-β1 had a significant decrease in the OPN expression as compared with control group (P<0.01).CONCLUSION:The expression of OPN in TGF-β1-induced LX-2 cells is regulated by the PI3K/PKB signaling pathway.

OBJECTIVETo explore therapeutic effect and action mechanism of regulating spleen-stomach needling on diabetic nephropathy (DN).

METHODSUsing multi-centric, randomized, controlled and blind principles, 144 cases of DN were divided into an observation group and a control group according to random digital tab, 72 cases in each one. Based on regular treatment of diabetes, the regulating spleen-stomach needling was applied at Zhongwan (CV 12), Quchi (LI 11), Hegu (LI 4) and Xuehai (SP 10), etc. in the observation group while Shenshu (BL 23), Taixi (KI 3), Sanyinjiao (SP 6), Yanglingquan (GB 34), etc. were selected in the control group by reference of Acupuncture and moxibustion. The treatment was given twice a day, six days as a treatment session with interval of one day between sessions. Totally six weeks were required. Changes of clinical symptoms and signs, fast blood glucose (FBG), urinary albumin excretion rate (UAER), beta2-microglobulin (beta2-MG), monocyte chemotactic protein-1 (MCP-1), lymphocyte membrane cholesterol, propanediol (MDA), PCO, 8-hydroxydeoxy guanosine (8-OHdG), superoxide dismutase (SOD), CD3+, CD4+, CD8+, and CD4+/CD8+ were observed before and after treatment in two groups.

RESULTSAs for improving clinical symptoms and signs, total effective rate was 84.29% (59/70) in the observation group and 55.56% (40/72) in the control group, which had statistical difference between two groups (P<0.01). As for regulating glycometabolism [(6.25 +/- 0.32) mmol/L vs (8.09 +/- 0.63) mmol/L], reducing UAER [(154.43 +/- 55.14) mg/24h vs (268.91 +/- 77.65) mg/24h], restraining over-expression of MCP-1 [(137.59 +/- 36.15) pg/mL vs (166.89 +/- 42.82) pg/mL], regulating level of oxidative stress, prohibiting oxidation of protein and adjusting quantity and activity of T lymphocyte subgroup, the observation group was superior to the control group (P< 0.05, P<0.01).

CONCLUSIONThe regulating spleen-stomach needling is an effective method for treatment of DN, which cold improve glycometabolism disturbance-induced progressive kidney injury, recover glomerular filtration, reduce urinary albumin excretion rate, restrain overexpression of MCP-1, adjust level of oxidative stress, prohibit oxidation of protein, increase protectiveness of membrane, adjust quantity and activity abnormity of T lymphocyte subgroup, leading to repairing lymphocyte damage and improving immune expression to delay kidney damage.

It was found that inflammatory reactions were alleviated gradually in the early stage . There was an increasing angiogenesis at late stage. Materials degraded and absorbed more slowly. Conclusion The present study sug?gests that the novel 3-D composite bionic network has good histocompatibility with easy vascularization, and will be a candi?date scaffold for bone tissue engineering.

Objective:To investigate the expression of serum human phosphatidylethanolamine-binding protein 4 (hPEBP4) in patients with multiple myeloma (MM) and its clinical significance.Methods:A total of 59 symptomatic MM patients admitted to West Branch of Beijing Chaoyang Hospital from September 2016 to September 2018 were selected as the research objects. According to the CRAB symptoms [elevated serum calcium (C), kidney injury (R), anemia (A), bone lesions (B)], all patients were divided into 2 groups, including the active group of 44 patients with CRAB symptoms, and the response group of 15 patients who achieved at least partial remission after chemotherapy and symptom relief of CRAB. According to the degree of bone lesions (BL), 30 patients with severe bone-related events were grouped as the severe bone lesions (SBL) group, and 14 patients were grouped as the non-severe bone lesions (NSBL) group. According to the revised international prognostic staging system (R-ISS), patients in the active group were divided into three subgroups: stage Ⅰ, stage Ⅱ, and stage Ⅲ, including 26, 11 and 7 patients, respectively. A total of 15 healthy examination people whose gender and age matched those of the patients were treated as the healthy control group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of hPEBP4, tumor necrosis factor ligand superfamily member 14 (LIGHT/TNFSF14) and activin A of patients in different groups. Pearson was used to analyze the relationship of the expressions of multiple factors in the active group. The optimal cut-off value of multiple factors diagnosing MM was determined by using receiver operating characteristic (ROC) curve, and according to the cut-off value, the differences in overall survival (OS) of patients with different stratification were compared.Results:In the active group, the respond group, the healthy control group, the level of hPEBP4 was (1.48±0.64) μg/L, (1.49±0.75) μg/L, (0.31±0.10) μg/L, respectively; the level of LIGHT/TNFSF14 was (169±112) ng/L, (256±132) ng/L, (44±27) ng/L,respectively; the level of activin A was (383±266) ng/L, (223±79) ng/L, (234±85) ng/L, respectively; and the differences were statistically significant (all P<0.05). In the active group, the level of hPEBP4 was (1.06±0.60) μg/L, (1.15±0.50) μg/L, (1.73±0.68) μg/L, respectively in patients with stage R-ISSⅠ, R-ISSⅡ and R-ISS Ⅲ, and the difference was statistically significant ( F=3.287, P=0.032). The level of activin A was (219±55) ng/L, (247±117) ng/L, (450±215) ng/L, respectively among patients in stage R-ISSⅠ, R-ISSⅡ, R-ISS Ⅲ, and the level of activin A in stage R-ISS Ⅲ was higher than that in stage R-ISSⅠand R-ISSⅡ (all P < 0.05). The levels of LIGHT/TNFSF14 and activin A of SBL patients were higher than those of NSBL patients [(174±101) ng/L vs. (98±53) ng/L; (467±238) ng/L vs. (189±71) ng/L, all P < 0.05]. The level of hPEBP4 was positively correlated with the levels of M protein ( r=0.694, P < 0.01) and activin A ( r=0.252, P < 0.01) of IgG patients in the active group. ROC curve analysis showed that the optimal cut-off value of hPEBP4, LIGHT/TNFSF14, activin A diagnosing MM was 1.04 μg/L, 97.0 μg/L, 156.2 ng/L. The median overall survival (OS) time of patients with hPEBP4 >1.04 μg/L and hPEBP4 ≤ 1.04 μg/L was 57 months (95% CI 22-92 months) and not reached, respectively, and the difference was statistically significant ( P < 0.05); while the median OS time of patients with activin A ≥ 156.2 ng/L and activin A < 156.2 ng/L was 61 months (95% CI 24-98 months) and not reached, respectively, and the difference was statistically significant ( P < 0.05). Conclusions:High expression level of hPEBP4 is related with the progression of MM. It is positively related with the level of M protein and negatively with the OS of MM patients. It is suggested that hPEBP4 may be used as an important marker to judge disease progression and tumor burden in MM. LIGHT/TNFSF14 and activin A cooperate with hPEBP4 to participate in the pathological processes of tumor microenvironment of MM.

OBJECTIVETo detect the salivary factors related to caries and periodontal disease and to analyze the risk of caries and periodontal disease in children and adolescents with diabetes mellitus.

METHODSThe study comprised 30 children with diabetic mellitus, aged 7-15 years old, and 60 healthy age-and gender-matched children. Caries and periodontal indexes were recorded and saliva related factors were analyzed.

RESULTSCaries indexes of diabetes children [permanent teeth: decay missing filling tooth (DMFT) M (Q1,Q3) = 0(0, 4), deciduous teeth: decay missing filling tooth (dmft) M (Q1,Q3) = 0(0, 1)] were not significantly different with those of healthy children [DMFT M (Q1,Q3) = 1(0, 3), dmft M (Q1,Q3) = 0(0, 4)], but plaque index (PLI) (1.25 ± 0.33) and bleeding index (BI) (0.74 ± 0.45) of diabetes children were significantly higher than those of healthy children (PLI was 0.93 ± 0.31,BI was 0.34 ± 0.22) (P < 0.001). Salivary pH of diabetes children (7.68 ± 0.36) was significantly higher than that of healthy children (7.30 ± 0.32) (P < 0.05), and salivary acid buffering capacity had no significant difference between the two groups (P > 0.05). Salivary glucose, immunoglobulin sIgA and sIgG were not significantly different between the two groups (P > 0.05).Salivary lysozyme of diabetes children was significantly higher than that of healthy children (P < 0.05). Total protein was significantly lower in diabetes children than in healthy children (P < 0.05). Salivary lactate dehydrogenase had no significant difference between the two groups (P > 0.05).

CONCLUSIONSDiabetes mellitus can lead to the changes of some salivary factors related to gingivitis in diabetes children. Children and adolescents with diabetes mellitus may have a higher risk of periodontal disease.
