Objective To Observe the influence of Zaoshi Jiedu Zhupi Sanjing (ZPSJ) Recipe on insulin sensitivity, serum resistin and inflammatory factors related to the effects of Chinese herbal compound in type 2 diabetic patients with insulin resistance. Methods A single-blind randomized controlled clinical trial was conducted. 80 patients with 2 type diabetic patients with insulin resistance were recruited into a control group and a treatment group. The treatment group was treated with ZPSJ Recipe, and the control group was treated with metformin. Results In each group before and after treatment: blood glucose, serum insulin levels, HOMA-IR were significantly decreased (t=7.14, P<0.01 ) ; between the two groups, FPG, FINS showed no significant difference, while TG TCH, HOMA-LR showed significantly differences (t=2.62, P <0.05 ). Within the two groups before and after the treatment: serum IL-6, TNF-a, hs-CRP were decreased in treatment group, (t= 1.85, P<0.05 ) , while TNF-a, hs-CRP were decreased in the control group (t=2.56, P<0.05 ) , while IL-6 did not change significantly. The serum resistin levels were not statistically changed in both groups before and after treatment. Conclusion ZPSJ Recipe can regulate blood sugar, blood fat and improve insulin sensitivity in type 2 diabetic patients with insulin resistance.

To investigate role of Notch1 - 3 in hyperoxia-induced lung injury in newborn rat exposed to 85% O2, SD rat litters born on the 22th day were randomly divided into two groups: room air group and hyperoxia group. The animals were sacrificed 1, 4, 7, 10, 14 and 21 days after continued exposure to oxygen (n = 40, oxygen > 0.85) or room air (n = 40). 6 rats each group were used to assess lung histological changes by HE staining and expression of Notch in lungs by immunohistochemistry. Total RNA was extracted by Trizol reagent from frozen lung tissues. Notch mRNA were measured by reverse transcription polymerase chain reaction (RT-PCR). Our results showed that 7, 14 and 21 days after O2 exposure, hyperoxia group showed lung injury characterized by pulmonary edema, hemorrhage and lung development arrest. Positive staining for Notch1, Notch 2 in hyperoxia group was much lower than those in room air group at all time points (P < 0. 01, P < 0.05), but compared with the controls, the hyperoxia group showed higher expression of Notch3 (P > 0.05). Immunostained cells were typically airways epithelia, alveolar epithelial and inflammatory cells, and fibroblasts in hyperoxia group (P < 0.01). Notch mRNA levels showed similar change as protein level (P < 0.01). It is concluded that the prolonged exposure to 85% O2 resulted in abnormal expression of Notch receptors, which might contribute to the pathogenesis of hyperoxia-induced lung injury in newborn rats. The decreased inhibition of Notch1 might be one of the protective reaction and major mechanisms for proliferation/differentiation of type II alveolar epithelial cells. The up-regulation of Notch3 activity might result in the lung development arrest of the newborn rats.

Objective To evaluate the reproducibility of Negative Expiratory Pressure(NEP)technique in detecting expiratory flow limitation (EFL) on chronic obstructive pulmonary disease (COPD) patients. Methods EFL was evaluated with NEP technique in 72 subjects having stable COPD on two occasions. Agreement between testing occasions was assessed with the κ statistic for the 3-point and 5-point EFL scores, and with paired t-test for FL index. Results On the first testing occasion, 18 subjects had no EFL, 18 subjects had EFL in the supine position, and 36 subjects in the sitting and the supine position. Using the 3-point score, agreement was present in 58 of the 72 subjects at time 2 (κ =0.69, P＜0.001 ), indicating a substantial agreement was found. Using the 5-point score, agreement was seen in 52 of the 72 subjects (κ =0.65, P＜0.001 ), also indicating a substantial agreement. The difference of FL index between the first and the second occasion was significant in both the sitting (P＜0.05) and supine (P＜0.05) positions. Conclusion Both 3-point and 5-point scores provided a reproducible assessment of EFL on COPD patients but the FL index seemed less reproducible. More research were needed before NEP technique was promoted to be used clinically.

OBJECTIVETo explore the effects of nano-hydroxyapatite/polyamide 66 (n-HA/PA66) cage on recovering and maintaining lumbar curvature, lumbar heights and fusion rate when used in the transforaminal lumbar interbody fusion.

METHODSFrom February to July 2012, 50 patients with degenerative lumbar disease(lumbar disc herniation in 32 cases and lumbar spondylolisthesis in 18 cases) were treated with transforaminal lumbar interbody fusion using the n-HA/PA66 cage, and their preoperative and postoperative clinical outcomes were analyzed. The patients were followed up for 2, 4, 6 and 8 months after operation, during which the CR and CT film of lumbar vertebra were checked to get relative height of vertebral space, Taillard index,index of lumbar spinal curvature,angle of segmental and full lumbar lordosis. The data were analyzed respectively with pair t-test, analysis of variance or LSD-t-test.

RESULTSAll the patients were followed up, and the duraion ranged from 8 to 13 months, with a mean of 11.32 months. There were significant differences in relative height of vertebral space, Taillard index, index of lumbar spinal curvature, angle of segmental and full lumbar lordosis after surgery, but there were no significant differences in different periods after operation. The fusion time of lumbar ranged from 4 to 8 months.

CONCLUSIONThe n-HA/PA66 cage can recover and maintain lumbar normal stability with higher rate of fusion and less complications.

Leukemia inhibitory factor (LIF) plays important roles in varieties of biological processes. This factor is highly conserved in mammalian animals and only one heterozygous LIF mutation was reported to cause the infertility of women. A LIF mutation was generated and the evidences were provided that the mutation of mature LIF at the 29th amino acid totally abolished its functions, including stimulation of STAT activation assayed by Luciferase reporter gene expression and EMSA experiments. In addition, the mutated LIF failed to inhibit the proliferation of M1 cells. The data indicated that the mutation of LIF did not have a dominant negative effect but lost the biological functions, suggesting that the 29th amino acid is critical for maintaining the activities of LIF.

Background Oxygen-induced retinal neovascularization is the main pathological basis for many retinal vascular diseases.Research showed that light exposure at night can suppress retinal neovascularization in oxygen-induced retinopathy(OIR),but there were few reports discussing its effect on ROP.Objective This study aimed to observe the effect of light exposure at night on retinal neovascularization in an OIR mouse model.Methods Sixty-four newborn C57 BL/6J mice were randomly divided into four groups,with 16 mice for each group.OIR models were established by rearing the newborn C57BL/6J mice with their mothers in a(75±2)％ oxygen environment from postnatal day 7(P7)to Pl2,and then transferred to room air.In the OIR model group,the environmental illumination level was the same as the normal control group,and the model mice were exposed to 100 lx light at night in the OIR+ light exposure group.In the simple light exposure group,normal mice were reared in room air and were exposed to light at night from P12 to P17.All the mice were sacrificed on P17,and retinal flat mounts were prepared to assess the oxygen-induced changes of retinal vessels using the adenosine diphosphatase(ADPase)histochemical technique.The amount of proliferative neovascularization was quantified by counting the number of endotheliocyte nuclei in new vessels extending from the retinal inner limiting membrane into the vitreous in ocular cross-sections.The expression of the vascular endothelial growth factor(VEGF)protein was detected by immunohistochemistry.Real-time PCR analysis was performed to examine the expression of VEGF mRNA.The rearing and usage of the animals complied with the Statement of ARVO.Results Less free-vascular areas and new blood vessels were seen in the OIR+light exposure group compared with the OIR model group.On day 17 of the mouse life,the number of the endotheliocyte nuclei in new vessels extending from retinal inner limiting membrane were 0.97±0.83,1.00±0.72,38.57±5.01 and 16.92±3.39 in the normal group,simple light exposure group,OIR model group and OIR+light exposure group,respectively,showing significant differences among them(F =78.767,P =0.000).The number of nuclei in the OIR+light exposure group were less than that of the OIR model group(t=20.446,P＜0.01).Immunochemistry showed that the expression of VEGF in retina was weaker in the OIR+light exposure group than the OIR model group.The relative expression values of VEGF mRNA were 1.00±0.00,0.94±0.07,2.08±0.50 and 1.43±0.21 in the normal group,simple light exposure group,OIR model group and OIR+light exposure group,respectively,showing a significant difference (F=11.268,P =0.003),where the VEGF mRNA level in the OIR+light exposure group was lower than that of the OIR model group(t =20.163,P＜0.05).Conclusions Light exposure at night can weaken retinal neovascularization in OIR mice
