Evaluation of fabric pilling using hybrid imaging methods

A study has been made on the quantification and evaluation of fabric pilling using two-dimensional and three-dimensional hybrid imaging methods. Two-dimensional imaging method was good for some samples while three-dimensional measurement method for others, according to the properties of their base fabric. Various image processing techniques as well as three-dimensional data processing algorithms were applied for the extraction of pills from measured data and a series of shape parameters have been defined for the objective evaluation of fabric pilling. An evaluation criterion that is compatible with the conventional evaluation method has been proposed by applying the new evaluation method to the current photographic standards.

Effects of blocking the expression of PKARⅠβ gene with antisense nucleotide on Shuang long-Jie gu Pill (SLJGP) containing serum osteoblast proliferation

AIM: To further investigate the role of PKARⅠβ in the growth-promoting effects of shuang long Jiegu pill (SLJGP), a Chinese medicine, on cultured osteoblasts. METHODS: pcDNA- antiPKARⅠβ, a recombinant expressing the antisense sequence of PKARⅠβ, was constructed and transformed HFOB1.19 by lipofectin. MTT was undertaken to assess the cell growth with the treatment of high dosage of SLJGP containing serum. RESULTS: Antisense gene blocked the growth-promoting effects of SLJGP containing serum on HFOB1.19. CONCLUSION: The function of SLJGP is closely related to cAMP-dependent protein kinase A.     

Role of Akt signal pathway in inhibition of neuronal apoptosis by Chinese medicine Zuogui pill in adult rats treated with monosodium glutamate

AIM: To explore the role of Akt signal pathway in apoptosis of neural cells in adult rats treated with Zuogui Pill, a Chinese medicine. METHODS: Flowcytometry and Western blotting methods were used to investigate the changes of cellular apoptosis rate and Akt signal pathway. RESULTS: Monosodium glutamate (MSG) could increase cellular apoptosis rate and significantly restrained the phosphorylation of Akt (Ser473) and Akt (Thr308), and markedly increased the levels of phospho-FKHR (ser256), GSK-3β (Ser9) and PTEN. Zuogui Pill partly inhibited the above effects of MSG. CONCLUSION: Zuogui pill effectively inhibits the neural apoptosis induced by MSG, and Akt pathway is involved in the neuronal protection of Zuogui pill.

犀角地黄汤加减联合血浆置换治疗急重型系统性红斑狼疮的疗效与机制研究

目的 探讨犀角地黄汤加减联合血浆置换（PE）治疗急重型系统性红斑狼疮（SLE）的疗效及作用机制。方法 纳入我院180例SLE患者,随机数字表法分为A、B、C三组。A组采取环磷酰胺冲击治疗、B组采取PE治疗,C组采取PE联合犀角地黄汤。比较三组治疗前后的症状评分、SLEDAI评分、补体C₃、血沉（ESR）、抗ds-DNA抗体、血清肌酐（Scr）、血清胱抑素（CsyC）、谷草转氨酶（AST）、谷丙转氨酶（ALT）、24 h尿蛋白、人干扰素-r（IFN-r）、白介素-10（IL-10）、BAFF因子,统计3组治疗总有效率及不良反应发生率。结果 B、C组治疗后各观察点的症状评分、SLEDAI评分、ESR、ds-DNA抗体、24 h尿蛋白、Scr、CsyC、AST、ALT、血清BAFF均低于A组（P<0.05）。C组治疗后各观察点的IFN-r^- IL-10⁺与IFN-r⁺ IL-10⁺亚群所占百分率低于A、B组（P<0.05）。B、C组治疗后各观察点的C₃高于A组（P<0.05）。B组与C组治疗总有效率为分别为90.0%、93.3%,均高于A组的71.7%（P<0.05）。C组不良反应发生率为10.0%,低于A组与B组（P<0.05,P<0.01）。结论 PE可去除血浆中有害成分、抑制炎症反应,联合犀角地黄汤可进一步扶助正气、解毒化瘀,改善机体免疫功能,达到增效减毒目的,效果更理想。     

Effects of Xijiao Dihuang and Yinqiao San decoction on ICAM-1 and VCAM-1 expression in mouse lung tissues and rat pulmonary microvascular endothelial cells infected with influenza virus

AIM：To investigate the effects of Xijiao Dihuang and Yinqiao San decoction (XDY) on the expression of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in mouse lung tissues and rat pulmonary microvascular endothelial cells (RPMVECs) infected with influenza virus, and to explore its mechanism for treatment of viral pneumonia. METHODS：Fifty-four male BALB/c mice were randomly divided into normal group, model group and XDY group (n=18 in each group). The viral pneumonia model was established by intranasally dripping influenza A (H1N1) virus into the mice. The mice in XDY group were treated with XDY 1 h after dripping the virus. The expression of ICAM-1 and VCAM-1 in lung tissues was examined by immunohistochemical staining 2, 4 and 6 d after infection. On the other hand, RPMVECs were obtained from male Wistar rats and primarily cultured. The cells were randomly divided into control group, virus group, virus+XDY group, tumor necrosis factor α (TNF-α) group and TNF-α+XDY group. The mRNA and protein expression of ICAM-1 and VCAM-1 was evaluated by real-time PCR and flow cytometry 24 h after infection. RESULTS：Virus exposure increased ICAM-1 and VCAM-1 expression in mouse lung tissues (P<0.01), and XDY treatment attenuated this effect (P<0.01). Virus and TNF-α both led to the increases in mRNA and protein expression of ICAM-1 and VCAM-1 in RPMVECs (P<0.01), which were also reduced by treatment with XDY (P<0.01). CONCLUSION：Treatment with XDY decreases virus-induced ICAM-1 and VCAM-1 expression, suggesting an important role of XDY in treatment of viral pneumonia.
