Background Optic neuropathy is one of the diabetic eye complications.Rosiglitazone,a peroxisome proliferator activated receptor γ(PPARγ) agonist,plays a very important role in arresting the pathogenesis and development of diabetes.However,the role of PPARγ in diabetic optic neuropathy is unclear.Objective This study was to investigate the protective effect of rosiglitazone against diabetic optic neuropathy and its mechanism.Methods Male Sprague-Dawley rats were randomly divided into the control group,diabetic group and rosiglitazone group,with 10 rats for each group.Diabetic models were induced by injecting 50 mg/kg of streptozotocin via the caudal vein,and rosiglitazone(5 ng/[kg· d])was used in the rats of the rosiglitazone group by intragastric administration every day for four weeks.At the end of the experiment,the fasting blood sugar(FBS) was tested in all the animals.The level of vascular endothelial growth factor(VEGF) in the blood plasma was detected by ELISA.Optical neural tissues were obtained from the rats of each group,and Lauck fast Blue myelin stain was used to examine the morphology of the optical myelin.The expression of neural cell adhesion molecule (NCAM) mRNA and protein in the optic nerve was detected by real time PCR and Western blot,respectively.Results The levels of FBS,blood plasma VEGF,NCAM mRNA and protein in the optic nerve were significantly different among the control group,diabetic model group and the rosiglitazone group after the administration of 5 nmg/(kg · d) rosiglitazone for 4 weeks (F =6.12,P＜0.01 ; F =5.14,P＜0.05 ; F =4.75,P＜0.05 ; F =4.87,P＜0.05).Compared with the control group,the level of FBS significantly increased in the diabetic model group(t =2.26,P＜O.05),and that in the rosiglitazone group significantly declined in comparison with the diabetic model group(t=2.08,P＜0.05).The optic nerve exhibited a normal morphology in the control group as revealed by the Lauck fast Blue myelin staining;however,severe demyelination of the optic nerve and proliferation of glial cells were found in the diabetic model group,and mild demyelination of the optic nerve and proliferation of glial cells were seen in the rosiglitazone group.Blood plasma VEGF was(28.76±4.21)ng/L in the control group and(134.28±11.36)ng/L in the diabetic model group,showing a significant difference between them (t=2.36,P ＜ 0.05).Compared with the model group,the blood plasma VEGF was significantly lower in the rosiglitazone group ([42.67 ± 5.83] ng/L) than that in the diabetic model group (t =2.17,P＜ 0.05).Expression of NCAM mRNA and protein in the optic nerve significantly decreased in the diabetic model group compared with the control group(t =2.21,t =2.58,both at P＜0.05);while those in the rosiglitazone group were significantly elevated in comparison with the diabetic model group(t =2.19,t =2.67,both at P＜O.05).Conclusions Rosiglitazone can protect optic nerve from damage in diabetic rats mainly by downregulating blood plasma VEGF level and upregulating NCAM expression.

BACKGROUNDWhether WW domain containing oxidoreductase (WWOX) gene is a tumor-suppressor is still controversial. Some researchers found that the transcription of the WWOX gene was lacking not only in tumor tissues but also in non-tumorous tissues and sometimes in normal tissues. Hence it is important to explore the role of the expression of the exogenous WWOX gene in the proliferation and apoptosis of primary cultured lung carcinoma cells.

METHODSLipofection technique was used to determine primary cultured lung carcinoma cells containing the highly expressed exogenous WWOX gene and primary cultured cells with vectors as controls. An animal model of lung cancer was made by subcutaneous implantation of tumor cells into nude mice. RT-PCR, Western blotting, flow cytometry, and TUNEL were used to detect the transcription, expression of the exogenous gene and the effect of the expression of targeted genes on the proliferation and apoptosis of the primary cultured lung carcinoma cells.

RESULTSThe growth, clone formation rate (CFR) ((5.33 +/- 1.53)%) of the primary lung cancer cells transfected with the WWOX gene, tumor size and weight were significantly lower than those of the non-transfected lung cancer cells (CFR: (14.33 +/- 1.53)%) and the primary lung cancer cells transfected with blank plasmids (CFR: (11.00 +/- 1.73)%, P < 0.05). The apoptosis level of primary lung cancer cells transfected with the WWOX gene ((40.72 +/- 5.20)%) was significantly higher than that of the non-transfected lung cancer cells ((2.76 +/- 0.02)%) and the primary lung cancer cells transfected with blank plasmids ((2.72 +/- 0.15)%, P < 0.05).

CONCLUSIONThe expression of the exogenous WWOX gene can significantly inhibit the proliferation of lung cancer cells and induce their apoptosis, suggesting that the WWOX gene possesses tumor-suppressing effect.

OBJECTIVETo observe amplitude changes of low frequency fluctuation in brain spontaneous nervous activities induced by needling at Hand Taiyin Lung Channel, and to preliminarily explore the possible brain function network of Hand Taiyin Lung Channel.

METHODSBy using functional magnetic resonance imaging (fMRI), 16 healthy volunteers underwent resting-state scanning (R1) and scanning with retained acupuncture at Hand Taiyin Lung Channel (acupuncture, AP). Data of fMRI collected were statistically calculated using amplitude of low frequency fluctuations (ALFF).

RESULTSUnder R1 significantly enhanced ALFF occurred in right precuneus, left inferior parietal lobule, bilateral superior temporal gyrus, bilateral middle frontal gyrus, left superior frontal gyrus, left inferior frontal gyrus, left medial frontal gyrus. Under AP significantly enhanced ALFF occurred in right precuneus, bilateral superior frontal gyrus, cerebellum, bilateral middle frontal gyrus, right medial frontal gyrus, and so on. Compared with R1, needing at Hand Taiyin Lung Channel could significantly enhance ALFF in right gyrus subcallosum and right inferior frontal gyrus. Significant decreased ALFF appeared in right postcentral gyrus, left precuneus, left superior temporal gyrus, left middle temporal gyrus, and so on.

CONCLUSIONNeeding at Hand Taiyin Lung Channel could significantly change fixed activities of cerebral cortex, especially in right subcallosal gyrus, right inferior frontal gyrus, and so on.

OBJECTIVETo study the clinicopathologic features and prognostic factors of gastrointestinal stromal tumor (GIST).

METHODSClinicopathologic data of 247 patients with GIST from January 2003 to November 2012 in the Affiliated Hospital of Qingdao University Medical College, and the prognostic factors were evaluated retrospectively by univariate and multivariate analysis with Log-rank test and Cox proportional hazard model.

RESULTSPatients were followed up with a median time of 26 months (1 to 113 months). Twenty-six patients developed recurrence or metastasis, and 18 died of GIST. The 1-, 3-, 5-year survival rates were 94%, 91% and 83% respectively. Univariate analysis showed that age, tumor location, tumor size, mitotic count and tumor rupture were predictive factors of survival after resection of primary GIST (all P<0.01). For patients at intermediate and high risk to relapse, imatinib group had a higher 5-year overall survival rate than non-imatinib group (85.7% vs. 81.0%, P<0.05). Multivariate analysis revealed that tumor size (RR=2.248, 95%CI:1.081-4.677, P=0.030), mitotic count (RR=2.220, 95%CI:1.032-4.776, P=0.041) and tumor rupture (RR=5.183, 95%CI:1.677-16.017, P=0.004) were independent prognostic factors.

CONCLUSIONSTumor size, mitotic count and tumor rupture affect the prognosis after resection of primary GIST independently. Imatinib adjuvant therapy can improve overall survival of patients at intermediate and high risk to relapse after surgery.

OBJECTIVEThis study aimed to investigate the effects of gene polymorphism of heat shock protein 70-2 (HSP 70-2) 1267A/G on the mRNA level HSP 70-2 mRNA and the protein level HSP 70 in human lung cancer.

METHODSForty six lung cancer patients diagnosed histopathologically between February and August 2008 from a hospital in zhengzhou were enrolled as the subjects in this study. Gene polymorphism of HSP 70-2 1276A/G in 46 patients with lung cancer was detected by PCR-RFLP. The mRNA levels of HSP 70-2 mRNA and the protein levels of HSP 70 in lung tissue and para-cancerous tissues of these subjects were determined by RT-PCR and Western blotting respectively.

RESULTSThe expression levels of HSP 70-2 mRNA (1.02 ± 0.30) and HSP 70 protein (0.44 ± 0.12) in the lung cancer tissues was significantly higher than that in para-cancerous tissues (0.19 ± 0.04, 0.12 ± 0.02). The relative levels of HSP 70-2 mRNA in the subjects with AA genotype (1.32 ± 0.22) were significantly higher than the patients with AG genotype or GG genotype (0.95 ± 0.17, 0.70 ± 0.16) at the site of 1267 (A/G) (P < 0.01); however, the relative protein levels of HSP 70 were 0.47 ± 0.13 (AA genotype), 0.42 ± 0.11 (AG genotype), 0.45 ± 0.11 (GG genotype), respectively, which showed no statistically significant difference (P > 0.05).

CONCLUSIONThe polymorphism of HSP 70-2 1267 (A/G) is highly associated with the transcription level of HSP 70-2 mRNA, but not with the expression level of HSP 70 protein.

OBJECTIVETo evaluate the stability of hearing results and complications in long-term following-up who underwent reconstruction surgery.

METHODSSix hundreds and seventy five cases (700 ears) of congenital aural atresia were reviewed from January 1984 to January 2001 at the Department of Otorhinolaryngology Head and Neck Surgery, Tongren hospital. Except 40 ears undone hearing reconstruction, 635 cases (660 ears) underwent long-term following-up for 3 to 19 years, with an average of 7.9 years.

RESULTSStenosis and recurrent infection of the external auditory canal (EAC) were the most frequent complications. Stenosis was seen in 120 ears, and 2 ears re-atresia, with an incidence of 18.48% (122/660). Recurrent infection of the cavity and canal skin happened in 6 ears. Closure of the air-bone gap (ABG) post-operation were gained in all cases, and ABG gains 20 dB or more occurred in 512 ears (77.57%), but 30 dB or more in 231 ears (35%). Following-up results: Stable hearing results gained in 450 ears over the length of following-up; the hearing worsened than that of 3 weeks postoperatively occurred in 160 ears, including 2 ears with sensorineural hearing loss. Hearing deteriorated more than 20 dB happened in 35 ears, and 10-15 dB in others cases but still be improved compared with that of preoperation.

CONCLUSIONSAtresiaplasty surgery in individuals with congenital aural atresia can yield reliable, lasting hearing results in 68.2% (450/660), with a low incidence of complications; the initial improved hearing deteriorated gradually over the first 6 months post-operation, which are related with the stenosis and infection of canal. Cavity adhesion, bony EAC re-growth, ossicular chain re-fixation or displace may affect the hearing results in some cases. Even unilateral aural atresia may benefit from the reconstruction surgery and achieve serviceable hearing results.

OBJECTIVETo explore the prevalence of vision, mental, audibility, language, psychiatry, extremity, and influence factors in the 0 - 7 year olds.

METHODSA total number of 77,727 0 - 7 year old children living in Shenzhen city were tested with tree phase screening under the Chinese standard of evaluation in disabilities.

RESULTSThe prevalence of all disabilities was 5.59 per thousand (adjusted rate was 8.49 per thousand with a false negative of 3.1 per thousand ). The prevalence of mental disease was the highest (1.88 per thousand, with adjusted rate 3.43 per thousand ), the prevalence of language disability was 1.88 per thousand (including retarded language development, with adjusted rate 3.43 per thousand ). The prevalence rates of psychiatry, extremity and audibility disability were 1.59 per thousand, 1.56 per thousand, 1.11 per thousand respectively with of vision the lowest (0.37 per thousand ). The prevalence of all disabilities, audibility, language and mental was on the increase with age. The difference was statistically significant. Among all different age groups regarding psychiatric disease, the highest fell in the 2 - 4 year olds. The prevalence of extremity was not statistically different among age groups. The suspected agents of disease which occurred before or during pregnancy took up 45.7%.

CONCLUSIONThe prevalence of six kinds disabilities in Shenzhen was about 10 per thousand lower than that of the samples of the nation in 1989, but two times higher than that of similar studies in Japan. The prevalence rates of language and psychiatric disease were higher than that of the nation in 1989. The causation should be further studied.
