Objective To summarize the experiences in the diagnosis and treatment of the hepatic hereditary hemorrhagic telangiectasia (HHHT).Methods The clinical data of 15 HHHT patients who were admitted to the Qilu Hospital,People's Hospital of Mengyin,People's Hospital of Liaocheng,Henan Provincial People's Hospital,the Second Hospital of Hebei Medical University,First Affiliated Hospital of Zhejiang University were retrospectively analyzed.The clinical manifestation,features of imaging and laboratory examination were summarized,and the diagnosis,treatment and prognosis of the disease were investigated.Results HHHT patients had nonspecific symptoms in the early stage,and some patients presented with right upper quadrant discomfort,shortness of breath,anemia and liver bruit.The condition of HHHT patients could be worsened by liver cirrhosis or portal hypertension rapidly.The results of color doppler ultrasound and computed tomography showed intrahepatic telangiectasia,arteriovenous fistula and hepatic artery aneurysm in the 15 patients.Digital subtraction angiography was not clear enough for 2 HHHT patients with more than 1 enlarged hepatic arteries,but computed tomographic angiography was feasible.According to the degree and stages of the HHHT,all the 15 patients were divided into asymptomatic HHHT,simple HHHT and complex HHHT.Among the 6 patients who underwent surgical treatment,5 received ligation or banding of the enlarged hepatic arteries with subsequent disappearance of symptoms.Three patients received interventional treatment,and the treatment for 1 patient with complex HHHT was failed,and the patient died 30 months after medical treatment.Six patients were treated by conservative treatment,2 patients of them had no symptoms at the beginning,then they suffered from hepatic dysfunction and ascites at 21 and 35 months,respectively,and 1 of them died 6 months later.Four patients received medical treatment,and the results of color doppler ultrasound and computed tomography showed the pathological changes were aggravated gradually.Conclusions Telangiectasia,intrahepatic arteriovenous fistula and hepatic artery aneurysm are the main imaging characteristics of HHHT,and imaging diagnosis has significant value in the diagnosis of HHHT.HHHT is a progressive disease,early,active and individualized treatment is beneficial to the patients.The outcome of ligation or banding of the hepatic arteries is satisfactory.

Objective To investigate the characteristic of MRS in patients suffered diffuse axonal injury (DAI)in acute and suba-cute stage,and the correlation between MRS changes and the severity of disease.Methods We reported MRI and proton magnetic resonance spectroscopy studies of 3 6 head-inj ured patients in acute and subacute stage.Proton magnetic resonance spectra were ac-quired from the white matter and gray matter of bibateral frontal lobe that on conventional MRI appeared normal by using 2D MRSI at 3.0T MRI .30 volunteers as contronl were studied at the same time.Results In patient group,N-acetylaspartate/creatine ratios were (2.14±0.15)and (1.71±0.08)choline/creatine ratios were(1.35±0.13)and (1.03±0.08)for the white matter and the gray matter,respectivily.The brain N-acetylaspartate/creatine ratio was reduced and the choline/creatine ratio was increased in pa-tient group compared with the controls.The increase in the choline/creatine ratio was significant even in the moderate and severe in-j ured groups.Furthermore,there was a significantly correlation between the severity of head inj ury and the N-acetylaspartate/cho-line ratio,and changes in patients with metabolite ratios of the GCS score had a strong correlation.Conclusion We conclude that DAI patients with normal conventional imaging manifestations of the frontal lobe appear metabolite ratio change,suggesting the existence of local cerebral inj ury,and it has a strong correlation between the prognosis and MRS changes.MRS may provide an useful method that can tell us the severity of the brain inj ury in patients with DAI .

OBJECTIVETo assess the association of a disintegrin and metallo-proteinase with thrombospondin type 1 motifs (ADAMTS-1) gene polymorphism and ischemic stroke caused by large artery atherosclerosis (LAA).

METHODSIn total 767 patients and 506 controls were recruited. Single nucleotide polymorphisms (SNPs) rs416905 (T/C) and rs402007 (G/C) of the ADAMTS-1 gene were genotyped by polymerase chain reaction and DNA sequencing.

RESULTSFrequencies of the rs402007 GC+CC genotype and the C allele were significantly different between the two groups (68.84% vs. 60.67%, χ2=9.012, P=0.003, OR=1.432; 45.24% vs. 38.54%, χ2=11.208, P=0.001, OR=1.318). Binary logistic regression has confirmed that the above difference was significant (P=0.001, OR=1.521, 95%CI: 1.183-1.955). The frequencies of TC+CC and GC+CC genotypes were similar between the two groups, and so was it with the C allele. The two SNPs had been in complete linkage disequilibrium (D'=1.0, r2=1.0).

CONCLUSIONThe rs416905 and rs402007 polymorphisms of the ADAMTS-1 gene may be associated with ischemic stroke caused by LAA. The C allele of the rs402007 locus may be a susceptibility factor for this subtype of stroke.

Background and objective Small-cell lung cancer (SCLC) is an aggressive disease for which the mainstay of treatment is cytotoxic chemotherapy. Despite good initial responses most patients will relapse or progress atfer the ifrst-line therapy. hTe evidence of a beneift from second-line chemotherapy is limited in patients with relapsed/advanced SCLC. Some drugs are recommended by guidelines, but more regimens are formulated based on experience in clinical. So we conducted this retrospective study in order to compare the effcacy and safety of different second-line treatment regimens. Methods We totally analyzed 309 patients received second-line treatment in our retrospective study. 157 patients received best supportive care (BSC), and the rest 152 patients received second-line chemotherapy. hTe Kaplan-Meier method survival curves and Log-rank test were used to analysis the differences among different groups. hTe endpoints were objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). Results Patients administered second-line chemotherapy lived signiifcantly longer, with a total OS from ifrst-line therapy of 11.5 mo compared to 6.0 mo in patients with best supportive care alone (P<0.001), and the ORR, DCR, PFS and OS of the former (including the sensitive dis-ease and resistance/refractory disease patients) were obviously better than that of the latter. hTe ORR and DCR of the patients who received second-line chemotherapy is 39.5%and 59.2%, respectively. hTe median PFS and OS from second-line chemo-therapy were 3.3 mo and 5.3 mo. hTe patients who received second-line chemotherapy were divided by types of second-line regimens. hTe sensitive disease patients were from group A (VP-16-based rechallenge) and group B1 (CPT-11-based regimen). hTe ORR of the two groups were 48.6%and 35.3%, and the DCR were 68.6%and 58.8%, respectively. hTere was no statistically signiifcant difference (P=0.264;P=0.400). hTe median PFS from second-line chemotherapy of the two groups were 4.0 mo and 3.0 mo, and the second-line median OS were 6.5 mo and 4.5 mo. hTere was no statistic difference (P=0.432;P=0.508). hTe resistance/refractory disease patients were divided into group B2 (CPT-11-based regimen), group C (PTX/DXL-based regi-men) and group D (TPT-based regimen). hTere was no statistic difference in second-line ORR, DCR and median PFS among the three groups (P value is 0.521, 0.528 and 0.775, respectively);hTe median OS from second-line chemotherapy of the group D is longer than that of group B2 and group C, with statistical difference (P=0.043;P=0.030). hTe differences of grade III-IV hematologic toxicities among the four subgroups were not statistically different. hTe incidence of diarrhea in non-hematologic toxicities in patients who received irinotecan as second-line chemotherapy was higher than other three subgroups (P=0.029). Conclusion Patients who progressed atfer the completion of ifrst-line chemotherapy can gain survival beneift. hTe response and the PFS of the different second-line chemotherapies were similar. hTe patients who received the TPT-based regimen may gain longer overall survival than other resistance/refractory disease patients.
