Objective To observe the histopathologic and ultrastructural characteristics of cornea and adjacent conjunctiva in Mooren’s ulcer. Methods The samples of limbal and central cornea and adjacent bulbar conjunctiva taken from active Mooren’s ulcer after lamellar keratoplasty were cut into paraffin sections and ultrathin sections and observed by light and transmission electron microscopy. The samples taken from patients of a Terrien’s marginal degeneration and a bacterial corneal ulcer were used as controls. Results Chronic inflammation including lymphocytes and plasma cells infiltrating existed in bulbar conjunctiva and sclera of Mooren’s ulcer. Limbal corneal epithelium, Bowman’s membrane, anterior stroma and adjacent superficial sclera melted and the inferior stromal collagen disorganized. The epithelial basement membrane of ulcer progressive edge had been destroyed while the epithelium and stroma kept quiescent. Lymphocytes infiltrated in conjunctiva and corneal epithelium of Terrien’s marginal degeneration with normal epithelial basement membrane, while Bowman’s membrane was destroyed. The epithelial basement membrane of bacterial corneal ulcer was intact. Conclusion Bulbar conjunctiva may act as a local lymph node of Mooren’s ulcer. Epithelial basement membrane of Mooren’s ulcer may have some abnormality as it was invaded first during ulcer progressing and it’s valuable to have a further study.

OBJECTIVETo explore the correlation among prevertebral hyperintensity (PVH), sagittal canal diameter on MRI and neurologic function of patients after cervical vertebral hyperextension injury without fracture and dislocation.

METHODSThe clinical data of 100 patients with cervical vertebral hyperextension injury without fracture and dislocation were retrospectively analyzed from September 2010 to December 2013. The patients were divided into PVH group and non-PVH group according to the presence of PVH on T2-weighted magnetic resonance imaging. There were 39 patients in PVH group, including 31 males and 8 females, aged from 21 to 83 years old with an average of (58.10 ± 14.78) years; and the other 69 patients in non-PVH group, including 49 males and 12 females, aged from 32 to 77 years old with an average of (55.05 ± 10.36) years. The sagittal disc level canal diameters of subaxial cervical spine were measured on mid-sagittal magnetic resonance imaging. The age, sex, cause of injury, and the segments of spinal stenosis were recorded. American Spinal Injury Association (ASIA) impairment scale and motor score were used to evaluate the neurological status.

RESULTSThe ASIA motor score of the group with PVH was 52.56 ± 31.97 while the ASIA motor score was 67.70 ± 22.83 in non-PVH group (P = 0.013). More patients with intramedullary hyperintensity signal on MRI were observed in the PVH group than in non-PVH group (P = 0.006). There was a significant positive correlation between ASIA motor score and sagittal disc level canal diameter of injury segment (P = 0.003). The neurological status was worse in patients with multi-level sagittal canal diameters below 8 mm.

CONCLUSIONThe PVH and the disc-level canal sagittal diameter of the injury segment are associated with neurological status. The patients with multi-level sagittal canal stenosis are vulnerable to severe cervical spinal cord injury.

OBJECTIVE: To evaluate the effect of asymmetric dimethylarginine (ADMA) and the results of losartan intervention on platelet-aggregation in spontaneous hypertensive rats. METHODS: Spontaneous hypertensive rats (SHR) were randomly assigned into 3 groups: SHR control group, L-arginine treatment group (L-arg) and losartan (los) treatment group, each group consisting of 16 rats. Another 16 Wistar Kyoto rats (WKY) served as normal control group. The L-arginine and losartan treatment groups received 1.0 g/kg L-arginine or 30 mg/kg losartan in 10 mL/kg distilled water daily through gastric tube for 2 weeks respectively, while the SHR and WKY groups received distilled water alone. All the rats took tap water and standard feed freely during the experimental period. Systolic blood pressure (SBP) was monitored by the tail-cuff method. At the end of the 2-week intervention, all the rats were sacrificed and the blood samples were collected from the carotid artery. The platelet-aggregation-rate, NO levels, eNOS activity, and ADMA levels both in the plasma and the platelets were measured. We got other platelet samples from the SD rats and incubated the platelets with blood vascular endothelium from the above 4 groups of experimental rats and the platelet-aggregation-rate was monitored as well. RESULTS: (1) Systolic blood pressure of the SHR was significantly higher, compared with that of the WKY (P<0.01), which were significantly reduced both in the L-arginine and losartan groups (P<0.01). (2) Platelet-aggregation-rate of the SHR was significantly higher, compared with that of WKY (P<0.01), which was significantly reduced both in the L-arginine and losartan groups (P<0.01). (3) NO levels both in the plasma and the platelets of the SHR were lower, compared with those of the WKY (P<0.05); and were elevated significantly both in the L-arginine and losartan groups,compared with those of the SHR (P<0.05); (4) Both the plasma and the platelet eNOS activities of SHR followed the same pattern of the NO levels in these groups (P<0.01). (5) In contrast, the plasma and platelet ADMA levels showed a reverse pattern (P<0.05). (6) Platelets from the SD rats incubated with vascular endothelium of WKY exhibited lower platelet-aggregation-rate,compared with the platelets incubated with SHR vascular endothelium (P<0.05); Platelet-aggregation-rate of the SHR group increased, compared with that of the WKY group (P<0.05); Platelet-aggregation-rate both of L-arginine and losartan groups reduced, compared with that of the SHR group (P<0.05). CONCLUSION High levels of ADMA both in the plasma and in the platelets of SHR are associated with the decline of eNOS activity and NO levels, which might be an important reason for the increased platelet-aggregation-rate. Intervention with Losartan can reduce the platelet-aggregation-rate simultaneously with its known anti-hypertensive effect. The possible mechanism might be that losartan can enhance the eNOS activity and elevate NO levels through the suppression of ADMA.

BACKGROUNDVascular smooth muscle cell proliferation is an important process in the development of atherosclerosis and is associated with other cellular processes in atherogenesis. Telmisartan is reported to have partial peroxisome proliferator-activated receptor (PPAR)-γ activating properties and has been referred to as selective PPAR modulators, but valsartan just blocks angiotensin II (AngII) type 1 (AT1) receptors. This study aimed to compare the different effects of telmisartan and valsartan on human aortic smooth muscle cells (HASMCs) proliferation.

METHODSAbility of telmisartan and valsartan to inhibit proliferation of HASMCs was evaluated by the Cell Counting Kit-8 (CCK-8) in continuous cell culture. Whether the antiproliferative effects of telmisartan and valsartan depend on their effects on AngII receptors or activating the peroxisome PPAR-γ was also investigated in this study.

RESULTSTelmisartan inhibited proliferation of HASMCs by 52.4% (P < 0.01) at the concentration of 25 µmol/L and the effect depended on the dose of telmisartan, but valsartan had little effect on HASMCs proliferation (P > 0.05) and no dose response. When tested in cells stimulated with AngII, telmisartan had the same inhibition of HASMCs by 59.2% (P < 0.05) and valsartan also inhibited it by 41.6% (P < 0.05). Telmisartan and valsartan had the same effect on down-regulating AT1 receptor expression and telmisartan was superior to valsartan up-regulating AngII type 2 (AT2) receptor expression. Antiproliferative effects of telmisartan were observed when HASMCs were treated with the PPAR-γ antagonist GW9662 but antiproliferative effects of the PPAR-γ activator pioglitazone were not observed.

CONCLUSIONSTelmisartan, but not valsartan, inhibits HASMCs proliferation and has dose-dependent response without stimulation of AngII. AT2 receptor up-regulation of telmisartan contributes to its greater antiproliferative effects than valsartan. Its PPAR-γ activation does not play a critical role in inhibiting HASMCs proliferation.

Aim To investigate the protective effects of supercritical CO2 fluid extract(SFE)of Notoginseng a-gainst glutamate-induced PC12 cells damage and the underlying mechanism. Methods PC12 cells were dealt with glutamate to establish cell models. MTT as-say,LDH method,Hoschst 33342 staining,Fluo-3 /AM fluorescence staining and Western blot were used to observe the changes of cell viability,intracellular Ca2 + concentration and the expression of protein that interacted with C kinase l(PICK1)and glutamate re-ceptors 2 (GluR2),respectively. Results Glutamate was cytotoxic to PC12 cells with an inhibitory concen-tration 50(IC 50 )of 25 mmol·L - 1 . Pretreatment with SFE(25,50,100 mg·L-1)and FSC231(100 μmol ·L-1 )and SFE(100 mg·L-1 )+FSC231(100μmol ·L-1 )remarkablely improved cell viability,reduced LDH leakage,decreased apoptosis rate,debased intra-cellular calcium concentration,decreased the expres-sion of PICK1 ,and increased the expression of GluR2 . Conclusions SFE of Notoginseng shows protective effects against glutamate-induced PC12 cell damage, and its mechanism may be related to the inhibition of PICK1 and the increase of GluR2 protein expression.

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.

OBJECTIVETo study the effect of Chinese herbal compound (CHC) on the expression of hepatocyte cytochrome P450IIE1 in rat model of alcoholic fatty liver (AFL).

METHODSThe AFL rats models were established by administering the drinking water with 40%(v/v) ethanol, and the changes of pathology in liver and hepatocyte P450IIE1 expression, as well as the contents of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), vitamin E (VitE) in liver were detected and compared with those in the control group.

RESULTSFatty degeneration in liver recovered normally in the CHC-treated group. Immunohistochemical and in situ hybridization examination showed that CHC could inhibit the hepatocyte cytochrome P450IIE1 expression markedly, and restore the contents of MDA, SOD, GSH, VitE to nearly normal range.

CONCLUSIONCHC can prevent AFL through inhibiting the hepatocyte cytochrome P450IIE1 expression markedly
