?AlM: To evaluate the expressions and significances of endoplasmic reticulum stress related protein ( BlP ) , hypoxia-inducible factor-1α ( HlF-1α) and vascular endothelial growth factor ( VEGF) in the retina of diabetic rats.
?METHODS:Seventy-two male Sprague-Dawley ( SD) rats were chosen and divided randomly into 6 groups:normal control 2mo (C2m, n = 12), diabetes mellitus 2mo (D2m, n=12), normal control 4mo (C4m, n=12), diabetes mellitus 4mo (D4m, n = 12), normal control 6mo (C6m, n=12) and diabetes mellitus 6mo (D6m, n=12 ) . The diabetes mellitus mouse were induced by intraperitoneal injection of 0. 1mol/L streptozotocin (STZ, 65mg/kg). The expression of BlP, HlF-1α and VEGF in the retina were detected by enzyme- linked immuno sorbent assay. The location of BlP, HlF-1α and VEGF in epiretinal membranes were investigated by immunohistochemistry staining.
?RESULTS: BlP were significantly increase than control groups in all DM groups with the course of diabetes ( P<0. 01). HlF-1α were detected higher than control groups in all DM groups (P< 0. 05), but there was no statistical significance among treatment groups. VEGF in D4m and D6m groups were higher than control groups (P<0. 05), and there was statistical significance between D4m and D6m groups. BlP can be detected in control groups a little, mainly in the inner limiting membrane and ganglion cell layers. HlF - 1α cannot be detected in control groups, meanwhile it can be detected in all layers in DM. VEGF can be detected in control groups a little, it mainly be detected in inner nuclear layer, outer nuclear layer, around retinal vessel and ganglion cell layers in DM groups.
?CONCLUSlON:The expressions of BlP, HlF-1α and VEGF increase in the retina of diabetic rats than control groups with progressive of diabetes mellitus, both endoplasmic reticulum stress and HlF-1α signal path play important role in the progress of diabetic retinopathy.

Objective To determine serum cytokine profiles and levels in patients with early diabetic retinopathy(DR)by using antibody array technology and analyze their clinical significances.Methods Among 32 patients with type 2 diabetes mellitus,16 patients with mild to moderate non-proliferative DR were as DR group;and 16 patients without retinopathy,as diabetic control group.Eight healthy subjects were selected as normal control group.The profiles of 42 cytokines were detected by human cytokines antibody array(Raybiotech).Results Compared with diabetic control group,in DR group,levels of epithelial neutrophil-activating peptide-78(ENA-78),growth related gene(GRO),regulated upon activation normal T cell expressed and secreted(RANTES),angiogenin,vascular endothelial growth factor(VEGF)and platelet-derived growth factor(PDGF)increased significantly(P

Aiming at the subject characteristic of medical imaging,the authors summed up and analyzed the objective,thought and project in the reform of medical imaging experiment teaching in our school to probe into the direction of the reform of medical imaging experiment teaching and raise some thoughts about how to culture qualified students of medical imageology.

AIM: To evaluate the relationship between axial length ( AL ) , corneal and lens refractive power, and the refractive error in children.
METHODS:Totally 44 children 88 eyes with refractive error who underwent retinoscopy with cycloplegia, to be measured spherical equivalent refractive error. Axial length was measured by a noncontact optical biometry ( ZEISS IOL-Master) , and corneal K and anterior chamber depth ( ACD) were also measured by the same machine. The refractive power of the lens was calculated by using the SRK formula. The patients were divided into 3 groups, myopia (SE<0), hyperopia (SE>+0. 50D) and emmetropia ( 0 to + 0. 50D ). Linear Correlation and Regression were used to evaluate the correlation among the optical parameters.
RESULTS:Totally 44 subjects, 88 eyes, average 9. 04±2.39 years, spherical equivalent (SE) -3. 50D to +8. 75D. Hyperopic AL was shorter than the other two groups ( P<0.05), same trend in lens power. No significant differences among the 3 groups in corneal K and ACD. There was a negative correlation between age and SE, SE and AL, SE and lens refractive power, and there was a positive correlation between age and AL, age and lens power.
CONCLUSION:As the children's growing up, SE trends to myopia, and AL becomes longer, and lens power is stronger.

OBJECTIVETo explore the feasibility and safety on lung resection surgery with the combined method of microinjection acupuncture (MIA) and intravenous anesthesia instead of compound traditional acupuncture and drug anesthesia (ADA).

METHODSNinety cases of lung resection surgery were randomized into a general anesthesia group, a MIA group and a ADA group, 30 cases in each one. In the general anesthesia group, before surgery, the intramuscular injection of atropine 0. 5 mg was used; during surgery, the anesthesia induction was followed with intravenous injection of fentanyl citrate, propofol and rocuronium bromide and the dosage was increased accordingly; after surgery, the analgesia pump was applied. In the MIA group, on the basis of general anesthesia, before anesthesia induction, the acupoint catgut embedding was applied to Jiaji (EX-B 2) of T4 , T6 and T, , Feishui (BL 13), Xinshu (BL 15) and Geshu (BL 17) on the affected side and bilateral Quchi (LI 11) and Zusanli (ST 36); after surgery, the analgesia pump was applied. In the ADA group, on the basis of general anesthesia, before! anesthesia induction, electroacupuncture (EA) was applied to Hegu (LI 4), Neiguan (PC 6) , Houxi (SI 3) and Zhigou (TE 6) for 30 min; during surgery, EA and intravenous medication were combined at the same acupoints as those before surgery; after surgery, moxibustion and the analgesia pump were applied in combination for analgesia. In each group, the biological indices were monitored during surgery at 11 time points named T. (before anesthesia I induction), T1 (intubation in general anesthesia induction), T2 (skin incision), T3 (rib exposure in muscular incision) T. (chest open), T, (lung removal), T6 (drainage tube implantation), T7 (chest closure), T (muscular stitching), T, (skin stitching) and T0 (extubation). The actual dosage of anesthetics during surgery and the, dosage of fentanyl citrate in analgesia pump were quantified after surgery. Results (1) In the MIA group and ADA group, the increased dosage of fentanyl citrate was less than that in the general anesthesia group [(1. 23±0. 28) µg . kg-1 . h-1 vs (2. 4±0. 54µg. kg-1 . h-1, (1. 1±0. 38µg . kg-1 . h-1 vs (2. 4±0. 54µg. kg-1 . h-1 , both P<0. 05]. The increased dosage of propofol and rocuronium bromide was not different during surgery among the groups (all P>0. 05). (2) In the MIA group and ADA group, after surgery, the increased dosage of fentanyl citrate was less than that in the general anesthesia group [(11. 0±1. 04)µg/kg vs (15. 4±1. 52µg/kg, (11. 5±1. 38µg/kg vs (15. 4±1. 52µg/kg, both P<0. 05], reducing by 25% in comparison. (3) The differences in heart rate and blood pressure at 11 time points during surgery were not significant among the three groups (all P>0. 05).

CONCLUSIONn The combined method of MIA and intravenous anesthesia significantly reduces the dosage of intravenous anesthetics during and after lung resection surgery as compared with ADA, presenting the similar analgesic effect as simple intravenous medication and the good safety. The combined method of MIA and intravenous anesthesia is much
