Up to now, a variety of microRNAs have been found in a number of studies, that specifically expressed in retinal neuroepithelial, lens, cornea and retinal pigment epithelium, in which miR-126 plays a certain role in the proliferation of tumor cells, the development of thymus lymphocytes and cardiovascular diseases.Some researches show that miR-126 has certain correlations with the formation of corneal neovascularization, the development of diabetic retinopathy, and the immune system related eye disease.In this paper, the current miR-126 in the role of eye disease mechanism and research progress were reviewed.

To investigate the neuroprotective of ligustilide (LIG) against glutamate-induced apoptosis of PC12 cells, cell viability were examined by MTT assay. Flow cytometry was applied to assay cell apoptosis rate. Intracellular calcium concentration was measured by using fluorescent dye Fluo-3/AM. Cytochrome C (Cyt C), Caspase-3, Bax and Bcl-2 protein expression were assayed by western blot. The results showed that glutamate is cytotoxic with an inhibitory concentration 50 (ID50) of 15 mmol · L(-1). Pretreatment with LIG (1, 5, 15 μmol · L(-1)) significantly improved cell viability. The apoptosis rate in glutamate-induced PC12 cells was 13.39%, and decreased in the presence of LIG (1, 5, 15 μmol · L(-1)) by 9.06%, 6.48%, 3.82%, separately. Extracellular accumulation of Ca2+ induced by glutamate were significantly reduced by LIG. The results of western blot manifested that pretreatment LIG could decrease the release of Cyt C from mitochondria, down-regulate Caspase-3 protein expression and up-regulate Bcl-2/Bax ratio, thereby protects PC12 cells from apoptosis. In summary, LIG had protective effect on glutamate-induced apoptosis in PC12 cells through attenuating the increase in intracellular Ca2+ concentration, and inhibiting the release of Cyt C from mitochondria to cytoplasm.

Insulin receptor substrate(IRS)-1 and IRS-2 expression levels of liver tissues and skeletal muscle in intrauterine growth retarded(IUGR)rats were investigated by RT-PCR and immunohistochemistry.An IUGR animal model was established by maternal nutrition restriction during pregnancy.IRS-2 expression level of liver tissue and IRS-1 expression level of skeletal muscle in IUGR rats at 0 and 3 weeks old were significantly lower than those in normal rats at the same age respectively,and insulin resistance was induced in IUGR,and these findings might be the molecular mechanisms susceptible to metabolic syndrome in IUGR rats.

OBJECTIVETo compare the clinical effective differences between acupuncture-moxibustion and Chinese herbs for functional dyspepsia with emotional disorder.

METHODSEighty patients were randomly divided into an observation group and a control group, 40 cases in each one. In the observation group, based on the basic treatment Zusanli (ST 36), Yinlingquan (SP 9), Zhongwan (CV 12), Danzhong (CV 17), Neiguan (PC 6), Taichong (LR 3), Ganshu (BL 18), Geshu (BL 17) and Danshu (BL 19) were selected once every day or every other day. The treatment was given 14 times. In the control group, based on the basic treatment individual therapy of Chinese herbs according to syndrome differentiation was applied,one dose a day. Patients were treated for 4 weeks in the two groups. The scores of self-rating depression scale (SDS), the main symptoms and satisfied degree by self-rating for treatment were observed before and after 4-week treatment in the two groups. Also, the rate and the average time of return visit were compared in 6 months after treatment. Results After treatment, the SDS scores and the main symptoms scores were all improved compared with those before treatment in the two groups (all P< 0. 05). After 4-week treatment, the improvement of the SDS score in the observation group was better than that in the control group (48. 9±8. 5 vs 53. 1±8. 0, P<0. 05). After 1-week treatment and 4-week treatment, the improvements of the main symptoms in the observation group were superior to those in the control group (2. 7 ± 1. 0 vs 3. 3±0. 9, 1. 5±0. 9 vs 2. 3±1. 1, both P<0. 05), and the satisfied degree scores by self-rating were better than those in the control group (3. 0±1. 1 vs 3. 8±1. 3, 2. 0±1. 4 vs 2. 9±1. 5, both P<0. 05). In 6 months after treatment,the return visit rate in the observation group was 42. 5% (17/40), and it was lower than 70. 0% (28/40) in the control group (P<0. 05). The average time of return visit in the observation group was less than that in the control group (1. 0±0.8 vs 1. 9±0. 7, P<0. 05).

CONCLUSIONThe effect of acupuncture-moxibustion or functional dyspepsia with emotional disorder is better than that of Chinese medicine.

OBJECTIVE To investigate the changes in serum HBV-DNA level in HBsAg positive patients before and after operation and their infectious risk in hospital.METHODS HBV markers(HBV-M) in serum was detected in 58 HBsAg positive patients by time-resolved fluoroimmunometric assay before operation.HBV-DNA level in serum of them before operation and at 3rd,and 7th day after operation was detected by real time fluorescent quantitative polymerase chain reaction.We also detected HBV-DNA in gastric drainage juice and abdominal drainage after operation.RESULTS HBV-DNA was detected in 27 of 58 HBsAg positive patients' serum,the positive rate was 46.1%.After operation,serum HBV-DNA was increased remarkably at 3rd and 7th day compared with before operation in these patients respectively(P

ObjectiveTo observe the effect of acetylcholine (ACh) on lipopolysaccharide (LPS) induced inflammatory model of rat alveolar macrophages, and to observe the effect of the acetylcholinesterase inhibitor physostigmine (Phy) on the anti-inflammatory effect of ACh.Methods The rat alveolar macrophages NR8383 were cultured in vitro, which were divided into five groups: blank control group, LPS group (stimulated with 1 mg/L LPS for 12 hours), LPS+ ACh group (0.01, 0.1, 1, 10, 100μmol/L of ACh were added for 5 minutes before LPS stimulation), LPS+ Phy group (1 mmol/L Phy was added for 5 minutes before LPS stimulation), and LPS+ ACh+ Phy group (1 mmol/L Phy and 10μmol/L ACh were added for 5 minutes before LPS stimulation). The supernatants were collected in each group, the enzyme-linked immunosorbent assay (ELISA) was used to assay the contents of tumor necrosis factor-α (TNF-α), interleukins (IL-1β, and IL-6). The activity of acetylcholine esterase (AChE ) in the supernatant was also determined.Results① The contents of TNF-α (ng/L: 605.09±57.13 vs. 34.07±8.62), IL-1β (ng/L: 377.09±28.55 vs. 32.33±10.62) and IL-6 (ng/L: 558.04±77.45 vs. 42.62±11.21) in the LPS group were significantly higher than those in the blank control group (allP< 0.05). These results indicated that the inflammatory model of rat alveolar macrophages was constructed successfully.② ACh with the final concentrations of 0.01, 0.1, and 1μmol/L had less influence on the production of TNF-α, IL-1β and IL-6 in the culture supernatants of alveolar macrophages stimulated with LPS compared with LPS group (allP> 0.05). Nevertheless, 10μmol/L and 100μmol/L ACh notably reduced the production of TNF-α (ng/L: 451.19±30.67, 332.19±32.19 vs. 604.96±22.56), IL-1β(ng/L: 261.08±24.78, 143.98±28.39 vs. 367.06±10.44) and IL-6 (ng/L: 342.75±54.60, 235.48±29.75 vs. 562.69±63.34) in the culture supernatants compared with the LPS group (allP< 0.05).③ The activity of AChE in the LPS group was significantly higher than that in the blank control group (kU/L: 5.21±0.63 vs. 3.09±0.10,P< 0.05). The activity of AChE was successfully inhibited by 1 mmol/L acetylcholinesterase inhibitor Phy pretreatment compared with that in the LPS group (1.51±0.12 vs. 5.21±0.63,P< 0.05).④ The level of TNF-α (ng/L: 183.17±35.44 vs. 451.19±30.67), IL-1β (ng/L: 91.49±12.27 vs. 261.08±24.78) and IL-6 (ng/L: 108.17±22.82 vs. 342.75±54.60) in the culture supernatants of LPS+ ACh+ Phy group was significantly decreased as compared with LPS+ ACh group (allP< 0.05).Conclusions ACh with the final concentrations of 10μmol/L and 100μmol/L can inhibit the LPS induced inflammatory reaction in alveolar macrophages. The acetylcholinesterase inhibitor Phy can reinforce the ACh-mediated anti-inflammatory effect on alveolar macrophages inflammatory model.
