Objective To observe the effect of intact vagus nerve stimulation(IVNS)on liver inflammation and mRNA expression of suppressors of cytokoine signaling(SOCS)in rats. Methods Eighty Sprague Dawley rats were randomly divided into control group(n=20),sham group(n=20),LPS group(n=20,with intravenous injection of LPS to induce system inflammatory response)and LPS +IVNS group(n=20,with intact vagus nerve stimulation after LPS administration).The level of TNFαand IL-10 in the liver was detected with enzyme linked immunosorbent assay at 0,2,4,6 hours post-injection time.mRNA expressions of SOCS1 and SOCS3 in the liver were also determined with reverse transcription and polymerase chain reaction(RT-PCR). Resuits The liver TNFαin LPS+INVS group was lower than that of LPS group after LPS injection at 2,4 and 6 hours(P＜0.05).Compared with LPS group,liver IL-10 level in LPS+IVNS group was higher(P＜0.05)at post-injection time points(4 and 6 hours).After four hours of LPS challenge,mRNA expressions of both SOCS1 and SOCS3 were significantly increased.Compared with LPS group,mRNA expression of SOCS3 in LPS+INVS group was upregulated more significantly(P＜0.01),while mRNA expression of SOCS1 showed insignificant difference. Conclusions IVNS can depress liver inflammation and the anti-inflammatory mechanism involves SOCS signal transduction pathway.

AIM:To observe the clinical effect of femtosecond laser assisted penetrating keratoplasty.
METHODS: Twenty-four cases ( 24 eyes ) with corneal lesions were performed with femtosecond laser assisted penetrating keratoplasty. Preoperative and postoperative endothelial cell density and visual quality were compared.RESULTS: One week after operation, corneal grafts were clear in 21 eyes (87. 5%), mild cloudy in 3 eyes (12.5%);visual acuity ≥0. 5 in 18 eyes (75. 0%), 0. 2 ~0.4 in 6 eyes ( 25. 0%). After 3mo the mean corneal astigmatism was 2. 16±0. 21D ( range 2. 25 ~ 3. 09D). Compared to conventional penetrating keratoplasty which mean corneal astigmatism was average 3. 67±0. 38D after operation, there was significant difference between two groups ( P< 0. 05 ). There were significant differences between preoperative and postoperative visual acuity and astigmatism (both P<0. 05).
CONCLUSION: Femtosecond laser assisted penetrating corneal transplantation operation can improve patient's visual quality. And compared to traditional penetrating keratoplasty astigmatism decreased significantly, incision can be made in individual shape more precisely and neatly.

In the book of Chinese Acupuncture and Moxibustion by CHENG Dan-an, direct moxibustion with moxa cone was regarded as a classic style of moxibustion because of its innate character of heat induced thermal stimulus and burn toxin. CHENG Dan-an made the quantity of moxibustion more controllable through the selection of moxa wool, the size and number of moxa cones, and the tightness of moxa cones, etc. CHENG Dan-an 's clinical experience is summarized through treating stubborn and infectious diseases with direct moxibustion with moxa cone. The results showed that only with understanding the characteristics of moxibustion and key pathological mechanism of suitable disease could direct moxibustion with moxa cone and the appropriate methods be performed correctly. CHENG Dan-an confirmed the clinical effect of treating stubborn and intectious diseases with direct contact moxibustion with moxa cone, and optimized the specific operation scheme of direct moxibustion with moxa cone. It tell us that we should deeply study on moxibustion, to make it wide spread in the hereafter, bring benefit to mankind.

One step dot-ELISA method for the rapid determination of ABO blood groups in humam body fluids(or stains)was established using enzyme-labelled anti-A,--B and anti--H monoclonal antibody (McAb).The sample was applied on the nitrocellulose membrance as a dot. After washing, the appropriate McAb wasadded on top of the dot, and then followed by adding 3, 3'-diaminobenzidine(DAB). The brown color indi-cated the positive reaction. The ABO blood typing of 521 saliva samples including both secretor and non-se-cretor were carried out. All the results were correct. The advantages of this method are accurate, sensitive,rapid, easy to perform, as well as not time consuming. It is more sensitive than the conventional hemaggluti-naton inhibition test.

Objective To investigate the feasibility of quantitative measurement of fat concentration by CT spectral imaging in a mice model of fatty liver.Methods Twenty-four mice with different degrees of fatty liver underwent CT spectral imaging.CT values of liver parenchyma under mixed X-ray energy and 65 keV,fat concentration based on various basic material pairs (fat/water,fat/io-dine,fat/calcium)and spectral curves were obtained.Liver specimens were obtained to measure the concentration of triglyceride , and HE staining was performed.Correlations between various CT indexes and triglyceride concentration were analyzed.Results Correlation between fat concentration (fat/water pair)and triglyceride (r =0.91 5 )was better than that between CT values on 65 keV and triglyceride (r=-0.858),as well as polychromatic CT values (r=-0.81 6).All the P values were<0.001.Correlations between fat concentrations based on fat/iodine or fat/calcium pairs and triglyceride were relatively low (r=-0.726,-0.660).CT indexes on 1.25 mm slice thickness performed better than those on 2.5 mm.With fatty liver degree increased,the shape of spectral curve changed gradually.Conclusion Liver fat concentration can be measured by CT spectral imaging noninvasively,accurately and quantitatively in a mice model of fatty liver.

BackgroundCorneal neovascularization (CNV) is a common eye disease.The researches on the pathogenesis and treatment of CNV are focus in Ophthalmology.ObjectiveThis study was to investigate the effects of culture supernatant from human amniotic epithelial cells (AECs) on CNV in vitro and its mechanism.MethodsHuman AECs were obtained from a placenta and cultured in serum-free medium for 48 hours,and the supernatant was collected.The levels of interleukin-1 receptor antagonist (IL-1 Ra) and pigment epithelium-derived factor (PEDF) in the human AECs culture supernatant were detected by enzyme-linked immunosorbent assay (ELISA).Rabbit corneal epithelial cells (CECs) were obtained and cultured in different concentrations of human AECs culture supernatant for 48 hours,serum-free medium was used as the control group.The expression of vascular endothelial growth factor (VEGF) mRNA and basic fibroblast growth factor (bFGF) mRNA in rabbit CECs were measured by quantitative real-time PCR (QRT-PCR).Human umbilical cord vein endothelial cells (UVECs) were cultured in the three mediums above,and the proliferation of human UVECs (absorbance value,A value) was tested by the cell counting kit 8 ( CCK8 ).Migration assay was performed by the wound healing method for the human UVECs.The membrane ultra-structure of human UVECs was examined under the atomic force microscope (AFM).ResultsCultured and passaged human AECs showed a positive response for keratin.The expression of VEGF mRNA (1.00±0.22) and bFGF mRNA (1.00±0.36) in rabbit CECs was suppressed by the human AECs culture supernatant,with a significant reduction in comparison with the serum-free DMEM group (2.98±0.46,2.55±0.48 )(P=0.001,0.002).The A value was significantly lowered in the human AECs culture group for 72 hours compared with the serum-free DMEM group ( 1.941 ± 0.036 versus 2.144 ± 0.059 ) ( P =0.000 ),and the bFGF-induced migration rate of human UVECs was strongly inhibited by the culture supernatant of human AECs in comparison with serum-free DMEM.The plasma membrane of human UVECs cultured with the human AECs culture supernatant was full of bumps,and decreased intercellular connection and cellular pseudopodia were found on the AFM image.The concentration of IL-1Ra was (153.56±0.36)ng/L and that of PEDF was (70.41 ±0.68 )μ,g/L in the human AECs culture supernatant.Nothing was deteched in serum-free DMEM group.Conclusions Human AECs culture supernatant suppressed the expression of VEGF and bFGF in CECs as well as the migration and proliferation of vascular endothelial cells.The effect may be associated with IL-1Ra and PEDF secreted by human AECs.These results suggest that human AECs may be a potential therapy for the inhibition of CNV.
