0.05).Frequencies of P12A12 genotype and A12 allele in DN group were significantly decreased respectively,when compared with DN-0 group(for P12A12 genotype,9.1% vs 18.1%,P=0.034,OR=0.453;for A12 allele,4.5% vs 9.0%,P=0.041,OR=0.479). Conclusion The observations suggest that P12A polymorphism of PPAR?2 gene is associated with Chinese type 2 diabetic nephropathy,and A12 allele may protect the development of diabetic nephropathy in type 2 diabetic patients of Chinese.

Objective To explore the relationship between Arg913Gln(G→A) polymorphism of solute carrier family 12 member 3 (SLC12A3) gene and diabetic nephropathy (DN) in type 2 diabetes mellitus (T2DM) in Han population of Shanghai. Methods Two hundred and fifty-eight Han ethnic people in Shanghai with T2DM (T2DM group) were divided into non-DN group (DN0 group, n=95) and DN group (n=163) according to 24 h urine albumin excretion rate (AER), and those in DN group were subdivided into microalbuminuria group (DN1 group, n=95) and macroalbuminuria group (DN2 group, n=68). Besides, 82 people with normal results of oral glucose tolerance test (OGTT), without diabetes mellitus and nephropathy were served as controls. PCR-sequencing was used to detect the genotypes of Arg913Gln polymorphism of SLC12A3 gene. Genotypic and allelic frequencies and clinical characteristics were compared among groups. Results Three genotypes (GG, GA and AA) were detected. The frequencies of GA+AA genotype and A allele in T2DM group were higher than those in control group, while there was no significant difference between groups (P>0.05). There was no significant difference in genotypic or allelic frequencies among subgroups of T2DM group (P>0.05). The level of triglyeeride (TG), AER, level of fasting insulin (FINS) and HOMA-IR in patients with GA+AA genotype were significantly higher than those in patients with GG genotype in T2DM group (P<0.05). Conclusion Arg913Gln(G→A) polymorphism of SLC12A3 gene is not significantly associated with T2DM and DN in Han population of Shanghai. The AER of people with GA+AA genotype is significantly higher than that with GG genotype. Arg913Gln (G→A) polymorphism of SLC12A3 gene may predict the risk of increase of albuminuria in patients with T2DM in Han population of Shanghai.

Pancreatic ductal carcinoma accounts for 85％-90％ in pancreatic cancer, followed by the pancreatic cellendocrine tumors and pancreatic acinar cell carcinoma.In addition, mesenchymal cell carcinoma of pancreas is rare, and a mixed pancreatic cancer from 3 cells carcinoma is extremely rare.And pancreatic cancer always assume hypovascular tumor,spontaneous rupture of pancreatic cancer is rarely reported.A patient with a mixed duct-acinar-islet cell tumor of pancreas was admitted to the Second Affiliated Hospital of Harbin Medical University in June 2014, and underwent emergent operation of intraabdominal bleeding due to spontaneous rupture of tumor.The follow-up was done up to January 20, 2015.The patient died of intraabdominal widespread implantation metastasis of pancreatic cancer.A mixed duct-acinar-islet cell tumor of pancreas is extremely rare and easy to metastasis and diffusion of tumor with a rapid disease progression and a poor prognosis of patient,while operation is the key to terminate deterioration of the condition, and is the last line of defense to save lives.

0.05).Genotype CT frequency in T2DM group was significantly increased when compared with non-DM control group(P=0.012,OR=2.254).Conclusion Pro198Leu polymorphism of GPX-1 gene increases the risk of type 2 diabetes in Han Chinese of Shanghai,while T allele is not a risk factor of diabetic CHD.

0.05). Conclusion Preproghrelin-Leu72Met is not significantly associated with T2DM and DN in Shanghai Han populations,while T2DM with AA genotype is characterized by significant declination in urine microalbumin when compared with CA and CC genotypes.Leu72Met polymorphism(C→A)may postpone the development of microalbuminuria in T2DM subjects.

OBJECTIVETo discuss the objective characteristics and mechanism of nystagmus direction, intensity and time in horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV) .

METHODSA total of 233 patients with HSC-BPPV, whereas 179 horizontal semicircular canalithasis (HSC-Can) and 54 horizontal semicircular cupulolithiasis (HSC-Cup) were involved respectively. The induced nystagmus in roll tests recorded by video-nystagmograph(VNG) , whose direction, intensity and time characteristics were compared in various BPPV.

RESULTSHorizontal nystagmus was both induced by turning left or right in HSC-BPPV roll tests. The direction of the induced nystagmus was the same with turning in HSC-Can. The latency, duration time and intensity ([AKx(-)D] ± s) turning to lesion and normal side were (1.922 ± 1.501)s and (1.447 ± 0.855)s, (25.620 ± 10.409)s, and (22.110 ± 10.931)s, (56.441 ± 33.168)°/s and (24.239 ± 13.892) °/s in HSC-Can. The latency, duration time and intensity turning to lesion side were larger than normal side (t = 3.715, 15.219 and 4.070, P < 0.01) , the difference was statistically significant, and the intensity rate was about 2: 1. The direction of the induced nystagmus was opposite to turning in HSC-Cup. The intensity turning to normal side was larger than lesion side obviously. The intensity rate was about 2: 1, the difference was statistically significant (t = -7.634, P < 0.01) . While the latency and intensity of turning to lesion side in HSC-Can were larger than turn to normal side in HSC-Cup, and the difference detected no statistically significant difference (t = 1.554 and 0.305, P > 0.05).

CONCLUSIONSThe induced nystagmus intensity of head to two sides in roll tests for HSC-BPPV both follow Ewald's law, and the ratio between stronger and weaker are both 2: 1. These nystagmus parameters of VNG in roll tests are an objective guideline for BPPV diagnosis.

OBJECTIVETo research the frequency characteristics of the semicircular canals lesion in Hunt syndrome with vertigo and the clinical value of the video head impulse test (vHIT) for vestibular function evaluated in this disease.

METHODSThirty normal persons (control group) accepted the vHIT, 26 patients with Hunt syndrome with vertigo (study group) accepted low, mid and high frequency vestibular function tests, including caloric test (CT), head shaking test (HST) and vHIT. The parameters of the unilateral weakness (UW), head shaking nystagmus (HSN) and video head impulse test gain (vHIT-G) were observed. The correlations and characteristics of the results of the three tests in Hunt syndrome with vertigo deal were analyzed with SPSS 16.0 software.

RESULTSThe values of vHIT-G of the six groups semicircular canal in the control group were normal distribution without statistical significance (F = 0.005, P < 0.01), two sides anterior, horizontal and posterior semicircular canals vHIT-G average (x ± s) were (16.80 ± 9.80)%, (16.57 ± 10.30)%, (16.52 ± 11.12)% respectively; in the study group the separately vHIT-G of the three canals of the affected side were (46.96 ± 34.54)%, (75.35 ± 35.29)% and (41.65 ± 32.87)%, in which statistical significance comparing with the control group was detected (all P < 0.01); the positive one of the three tests vHIT, HSN and CT were 23 cases (88.46%), 22 cases (84.61%) and 24 cases (92.31%), bilateral exact probability χ² test all the P > 0.05;there were Positive correlation between UW and the vHIT-G of lateral semicircular canal (r = 0.692, P < 0.01).

CONCLUSIONSThe vestibular lesion of Hunt syndrome with vertigo is almost complete or multiple-frequency, which is characterized by the reduced or even aborted nerve conduction. Therefore, vHIT can be ultimately used for the screening test evaluating due to the vestibular function in Hunt syndrome with vertigo.

OBJECTIVETo investigate the relationship of serum metalloproteinase with the severity of liver fibrosis and inflammation.

METHODSA total of 88 patients with HBV-related liver fibrosis and early cirrhosis were enrolled from six hospitals. Serum fibrosis markers including hyaluronic acid (HA), IV collagen (IV-C), aminoterminal propeptide of type III procollagen (PIIIP), laminin (LN), matrix metalloproteinases (MMP) 1, 2, 9 and tissue inhibitors of metalloproteinase (TIMP) 1, 2 levels were determined. Liver biopsies were assessed according to a modified Scheuer and Chevallier's scoring system.

RESULTSSerum TIMP1 (r=0.540) and MMP2 (r=0.314) were correlated positively with the degree of hepatic fibrosis, whereas serum MMP1 (r=-0.495) was correlated negatively. By receiver operating curve analysis (ROC), the sensitivity to distinguish the fibrosis stage 2 from stage 1 was 90.5% and the specificity was 52.0% if the cut-off value of MMP1 was 13.96 ng/ml, and the sensitivity was 91.6% and the specificity was 64.0% if the cut-off value of TIMP1 was 76.84 ng/ml. The sensitivity to distinguish cirrhosis (stage 4) from fibrosis (stage 3) was 70.7% and specificity was 80.9% if the cut-off value of MMP1 was 6.86 ng/ml, and the sensitivity was 60.5% and the specificity was 92.3% if the cut-off value of TIMP1 was 210.04 ng/ml.

CONCLUSIONSerum TIMP1, MMP1, MMP2 levels and TIMP1/MMP1 ratio could be used as serum fibrosis markers.
