Rats were randomly divided into five group: normal control group, metabriolic syndome group, Rhizoma Coptidis apozem group, Berberine group, Metformin group. To estimate insulin resistance by euglycemic hyperinsulinemic glucose clamp(GC) tecchnique. To estimate expression of AMPK by using Western blot. Results: Compared with metabolic syndrome group, Rhizoma Coptidis apozem group had higher M-value, lower wet weight of innards fat, and higher protein level of p-AMPK-?. Conclusion: Rhizoma Coptidis apozem can improve insulin resistance, decrease innards fat, and regulate up expression of AMPK.

AIM: to assess the effectiveness of a combined procedure ( pars plana vitrectomy with temporary keratoprosthesis, vitreoretinal surgery, and penetrating keratoplasty). in the complicated cases and the risk factors for the surgical failure.METHODS: Restrospectively reviewed charts of patients who underwent penetrating keratoplasty in combination with vitreoretinal surgery between 1990 and 2005, with a follow-up of 3mo to 9a. Analysis was focused on ocular history, indications for surgery, visual acuity (VA), anatomic results, and complications.RESULTS: 18 eyes had light perception or VA of hand motions only. The best-corrected VA improved during the first 3mo, increased in 72.2% of all eyes, remained unchanged in 27.78%, and no decreased. In 3 of 18 eyes (16.67%), VA was better than finger counting and hand motions, and nine eyes(50%) showed useful vision (0.05) postoperatively. 10 eyes showed a clear corneal graft (55.56%). 2 eyes needs the second keratoplasty, Bullous corneal edema was evident in 3 eyes, band keratopathy was evident in a 3 eyes. 10 patients were observed for more than 2a;6 had a clear graft (60%). Two eyes (11.11%) had silicone oil-corneal endothelium contact and all of these grafts failed.CONCLUSION: Although the functional outcome of a combined procedure is limited by primary and secondary tissue destruction, preserving ambulatory vision is possible and thus improves the quality of life, at least in patients with single remaining eyes.

AIM: To investigate the differentiation of neural stem cells (NSCs) after transplanted into vitreous and the effects on the regeneration of retina ganglion cells (RGCs) after optic nerve microcrushed.METHODS: After optic nerve microcrushed in adult rat, 2?104/2 ?L NSCs or 2 ?L 0.1 mol/L PBS was injected into vitreous. Animals were divided into control group (MC group, MC+PBS group) and experiment group (MC+NSCs). Animals in each group were allowed to survive for 3, 4, 5 weeks, respectively. The regenerating RGCs were labeled retrogradely with granular blue, and the numbers of regenerating RGCs in each retina were observed under fluorescent microscope. In addition after 5 animals in MC+NSCs group survived for 4 weeks, rat eyeballs were removed and prepared as freezing microtome sections for observing the migration of NSCs and NF, GFAP, CNP immumodetection.RESULTS: Compared the mean numbers of regenerating RGCs between experiment group and control group at 3, 4, 5 weeks, the difference was significant (P

This study investigated the protective effect of ATP on skeletal muscle satellite cells damaged by H2O2 in neonatal rats and the possible mechanism. The skeletal muscle satellite cells were randomly divided into four groups: normal group, model group (cells treated with 0.1 mmol/L H2O2 for 50 s), protection group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h, and then with 0.1 mmol/L H2O2 for 50 s), proliferation group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h). MTT assay, FITC+PI+DAPI fluorescent staining, Giemsa staining and immunofluorescence were performed to examine cell viability and apoptosis, and apoptosis-related proteins. The results showed that the survival rate of skeletal muscle satellite cells was decreased and the apoptosis rate was increased after H2O2 treatment (P<0.01). Different doses of ATP had different effects on skeletal muscle satellite cells damaged by H2O2: the survival rate of muscle satellite cells treated with ATP at 4, 2, or 1 mmol/L was increased. The protective effect was most profound on cells treated with 2 mmol/L ATP. Immunofluorescence showed that ATP could increase the number of Bcl-2-positive cells (P<0.01) and decrease the number of the Bax-positive cells (P<0.01). It was concluded that ATP could protect skeletal muscle satellite cells against H2O2 damage in neonatal rats, which may be attributed to the up-regulation of the expression of Bcl-2 and down-regulation of Bax, resulting in the suppression of apoptosis.

Objective To explore the expression and significance of hedgehog signal molecules (Ptch, Smo and Gli1 ) in pancreatic cancer. Methods Two hundred SD rats were randomly divided into DMBA group ( group A, n = 90), cyclopamine intervening group ( group B, n = 90) and control group ( group C, n = 20).For group A and B, DMBA was directly implanted into the parenchyma of the pancreas to establish the model of pancreatic cancer. The rats in group B were treated with 6.25 ml/kg cyclopamine and DMSO solution intraperitoneally daily. All rats were sacrificed four months later to observe the pancreatic tissue pathologic changes, and immunohistochemistry SP was used to detect the expression of Ptch, Smo, Gli1 protein in pancreatic cancer and normal pancreatic tissue. Results The prevalence rate of pancreatic cancer in group A was 57.5％ (46/80), the maximum size of the tumor was 0.5 ～ ＞2 cm; the prevalence rate of pancreatic cancer in group B was 17.1％ ( 14/82), the maximum size of the tumor was 0.5 ～ 2.0 cm, and the difference between the two group was statistically significant (P ＜0.05). The positive expression rate of Ptch, Smo and Gli1 protein was 82.6％, 73.9％ and 65.2％ in DMBA group, and was 50.0％, 42.9％ and 28.6％ in cyclopamine group, and the difference between the two group was statistically significant ( P ＜ 0.05 ). Ptch,Smo and Gli1 protein was expressed in normal pancreatic tissue. Conclusions Direct implantation of DMBA in the parenchyma of rat pancreas can induce pancreatic cancer with a high incidence in a short time.Hedgehog signal protein expression is significantly increased, cyclopamine can inhibit the occurrence and progression of pancreatic cancer by inhibiting Hedgehog messenger expression.

Objective To investigate the clinical application of statins for secondary prevention and its efficacy in patients with ischemic stroke.Methods A total of 300 patients with ischemic stroke were divided into statins group (n=91) and control group (n=209) according to whether statins was received or not.Serum lipid parameters,liver and kidney function,carotid artery intimamedia thickness (IMT) and plaque area were compared between the two groups.Results In 209 patients not taking statins,68 cases (32.5％) were not advised by clinic doctor; 55 cases (27.8％)were reluctant to take statins in fear of adverse reactions; 77 cases (36.8％) discontinued stains when serum lipids were normal; 3 cases (1.4％) developed skin allergic reaction and the skin rash that disappeared after stains discontinuance; 3 cases (1.4％) had elevated liver enzyme levels and the enzyme levels were declined to normal after stains discontinuance.The levels of total cholesterol (TC),triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) were significantly lower in statin group than in control group [(4.93±0.45) mmol/L vs.(5.87±0.38) mmol/L,(1.68±0.61)mmol/L vs.(2.01±0.58) mmol/L,(2.49±0.57) mmol/L vs.(3.76±0.44) mmol/L,t=18.60,4.46,20.94,P=0.000,0.007,0.000,respectively].High density lipoprotein (HDL-C) level was significantly higher in stain group than in control group [(1.36±0.31) mmol/L vs.(1.03±0.25)mmol/L,t=9.75,P=0.001].There were no significant differences in liver and kidney function parameters such as alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase,serum total bilirubin,direct bilirubin,indirect bilirubin,glutamyl transferase,blood urea nitrogen and serum creatinine between the two groups (all P＞0.05).The carotid IMT and carotid atherosclerotic plaque area were significantly lower in stain group than in control group [(1.62 ± 0.23) mm vs.(1.74±0.31) mm,(0.57±0.12) cm2 vs.(0.65±0.18) cm2,t=3.32,3.88,P=0.008,0.002,respectively].Conclusions Most patients with ischemic stroke are still not taking statin for secondary prevention.Statins can improve the blood lipid levels and carotid arteriosclerosis status,and no obvious adverse reactions are observed.
