Objective: To investigate the impact for family history of hypertension on masked hypertension (MH) morbidity with relevant cardiac damage. Methods: Our research included in 3 groups: MH group, n=250 consecutive patients treated in our hospital from 2010-01 to 2015-04, Hypertension group, n=250 and Control group, n=250 subjects with normal blood pressure. The family history of hypertension, general clinical information, routine biochemical indexes and the findings of echocardiography were studied and compared among different groups. Results: ① There were 70 (28%) patients with family history of hypertension in MH group, 87 (34.8%) in Hypertension group and 26 (10.4%) in Control group. The ratio of family history of hypertension in MH group was higher than Control group, P<0.001, while it was similar between MH group and Hypertension group, P>0.05. Logistic regression analysis presented that family history of hypertension and body mass index were positively related to the morbidities of MH (r=1.468, r=0.173) and hypertension (r=1.195, r=0.086). ② Compared with Control group, MH group had increased left ventricular mass index (85.64 ± 17.7) g/m2 vs (80.50 ± 15.53) g/m2 and the maximum blood flow velocity of aortic valve (115.74 ± 16.54) cm/s vs (112.40±14.21) cm/s, all P<0.05. In MH group, compared with those without family history of hypertension, the patients with family history had the higher left ventricular mass index (89.22 ± 19.08) g/m2 vs (84.25 ± 16.99) g/m2 and the maximum blood flow velocity of aortic valve (119.19 ± 14.97) g/m2 vs (114.39 ± 16.96) g/m2, all P<0.05. Conclusion: The subjects with family history of hypertension had the higher risk of MH morbidity with more severe cardiac damage.

Fifty outpatients of newly diagnosed hypertension (NDH,with course of disease ≤ 3 months) and 50 patients with routinely revisit hypertension (RRH,with course of disease ≥ 1 year) were consecutively enrolled respectively from February 2010 to July 2010.They were asked to complete the Beck Depression Inventory (BDI),Spielberger State-Trait Anxiety Inventory (STAI) and the SF-36 questionnaire.The results showed that compared with the RRH group,the NDH group were more worried about being diagnosed as hypertension,dependence and side effects of antihypertensive drugs and complications of hypertension (all P ＜ 0.05).The NDH group displayed significantly higher level of anxiety compared with that of the RRH group (P ＜ 0.001).No significant differences were found in depression and 8 dimensions of SF-36 forms between two groups (P ＞ 0.05).The results indicated that patients of NDH have significant higher level of anxiety than that of RRH,they should be given more psychological intervention and appropriate health education.

Objective To discuss clinical,electroencephalogram(EEG) and PRRT2 gene mutation by reporting a febrile seizure (FS) with paroxysmal kinesigenic dyskinesia (PKD) family.Methods Detailed clinical data of the family were collected.The proband (Ⅳ1) and another 4 patients (Ⅲ1,Ⅲ4,Ⅳ2,Ⅳ3)were studied through clinical examinations.Clinical symptoms of Ⅳ2 were not typical,who was diagnosed as a suspected case.Mutation analysis of PRRT2 gene was screened by polymerase chain reaction (PCR) and DNA direct sequencing in 5 patients (Ⅳ1,Ⅲ1,Ⅲ4,Ⅳ2,Ⅳ3) and 4 unaffected family members (Ⅱ2,Ⅲ2,Ⅲ5,Ⅳ4).Results PKD patients had brief involuntary movements in the limbs or trunk induced by sudden voluntary movement when patients were in the stationary state since the teenagers.Two cases (Ⅲ,Ⅲ4) were accompanied by FS.Three cases(Ⅳ1,Ⅲ1 and Ⅲ4)had abnormal EEG records.The PRRT2 gene mutation (c.649dupC mutation) was identified in a healthy member (Ⅳ4) and 4 patients (Ⅳ1,Ⅲ1,Ⅲ4,Ⅳ3).Conclusions FS with PKD family has a PRRT2 gene mutation.The diagnosis is mainly based on family history,typical clinical manifestations and genetic test.This kind of disease may have pre-symptomatic patients.

Objective To evaluate the repairing effect of pedicle omentum on severe ureteral in-jury. Methods Twenty healthy dogs were randomized into the experiment group and the control group. Firstly the model of severe ureteral injury was made. In experimental group, the pedicle omen-turn were used to wrap up the severe injured ureter, but which was no done in control group. Urinary fistula and ureteral necrosis were observed. At 12 weeks postoperatively,the models were re-operated to investigate whether the severe injured ureters had healed. Angiogenesis, VEGF and its receptor KDR were also examined in stoma and surrounding tissue histopathologically. Results No urinary fistula was observed in experimental group, but 2 cases in control group were dead because of recurrent abdominal cavity infection after the formation of urinary fistula. The mucosa and smooth muscle of stoma were completely regenerated, and the blood vessels were regenerated more significantly in expe-rimental group than in the control group. In experimental group, the VEGF and KDR were over-ex-pressed, and the positive cell rates were (12. 65±0. 02)% and (10. 23±0. 03)%. But in control group, the stoma were not healed, and severe ureters1 strictures were observed in all dogs. Angiogene-sis was not signifieant, the VEGF and KDR positive cell rates were (1.54±0. 03)% and (2. 654± 0.04)%, respectively. Conelusions Pedicled omentum can promote the repair of severe ureteral in-jury. The mechanism may be the over expression of VEGF and KDR in prompting angiogenesis.
