Objective To investigate the surgical methods and effect of double-cut nasolabial muscle directional three-dimensional reconstruction on the secondary deformity of unilateral cleft lip repair.Methods We first increased a contralateral vermilion secondary incision based on the nasolabial muscle directional three-dimensional reconstruction, without damaging the contralateral white lip skin, via suturing both sides of nose wings bundle of nose outside corner under the columella muscle, and overlapping suturing both sides of the orbicularis muscle flap, and then rebuilt and took shape of the nest and the crest.Results All incisions healed well in 18 patients, all nasal deformities were corrected better than the traditional methods, with the nasal base plump, the nasal sill formed close to the contralateral side, and rebuild the philtrumdimple and philtrum crest, with clear appearance and symmetrical form.A good appearance was obtained on the both sides of nostril, nasal base and the nasal sill, and the effect of preoperative design achieved.Conclusions Both sides of the nostrils size, nasal sill and shape are almost perfectly symmetrical, and the double-cut nasolabial muscle directional three-dimensional reconstruction is suitable for repairing the secondary deformity after unilateral cleft lip repair.

Objective To design a new vermilion musculomucosal flap to reconstruct the normal appearance of unilateral cleft lip,and to analyze the clinical effects.Methods All patients were repaired with Millard method,and vermilion musculomucosal flap was formed with fixed point method to repair vermilion.Normal function and morphology were recovered by reconstructing lip beads and forming a peak of cupid's bow.Results 78 cases were enrolled in this study.They were followed-up for 6 to 36 months after operation.Except for 6 cases of nasal deformity and 5 mild lift of vermilion of affected side,67 cases obtained satisfied nasolabial form and function,with full decline and symmetry of cupid's bow peak,and well form of nasolabial fold,and natural transition of vermilion,and significance of lip beads,and inconspicuous scars.Conclusions Appling vermilion musculomucosal flap for reconstructing vermilion of unilateral cleft lip has good effect,and it is simple and feasible.It can be a regular surgery method,and is worthy of clinical promotion.

Objective To investigate the expression of c-erbB-2 and cathepsin D (cath-D) in primary breast carcinoma, and to analyze its relationship to the patients' clinicopathological status and its prognostic significance. MethodsThe immnohistochemical test were used to detect the expression of c-erbB-2 and cath-D in 128 patients with primary breast carcinoma. All data were statistically analyzed.ResultsThe positive expression rate of c-erbB-2 and cath-D was 36.5 % and 40.9 %, relatively. Cath-D was correlated with tumor size (x2 =21.0, P ＜0.0001) and lymph node status (35.29 % vs 63.83 %, P ＜0.0001). The Kaplan-Meier curve and log rank test indicated that the positive c-erbB-2 expression was a significant prognostic factor for patients disease free survival (P＜0.01). Conclusionc-erbB-2 and cath-D show a clinicopathological invasive characteristic. They are prognostic factors for patients with primary breast carcinoma, and also can be prognostic indicator for patients.

Objectlve To review the clinical characteristics,esophageal motility and acid exposure in elderly patients with gastroesophageal reflux disease (GERD).Methods Two hundred and sixty patients aged 18 -81 years were diagnosed as gastroesophageal reflux disease from 2005 to 2011 in outpatient clinic,the patients were divided into elderly group ( ≥ 60 y) and control group ( ＜ 60 y).The incidence of esophagitis,severity of esophagitis,esophageal motility and esophageal acid exposure were analyzed and compared between two groups.Results The incidence of esophageal hiatal hernia,non-typical reflux symptoms and extra-esophageal symptoms in elderly group were higher than that of control group(45.1％ vs.30.6％,36.3％ vs.27.2％ and 37.1％ vs.25.2％,P =0.016,0.005 and 0.037,respectively).There was no significant difference in esophagitis incidence between two group (55.8％ vs.50.3％,P =0.250).The incidence of esophagitis graded as LA-B to LA-D were higher in elderly group( 19.5％ vs.10.2％ and 8.8％ vs.2.7％,P =0.034 and 0.030,respectively).The percentage of upright acid clearance time,supine reflux time of pH ＜4 and the DeMeester score of elderly group were higher than those of control group (P =0.000,0.006 and 0.001,respectively).Lower esophageal sphincter pressure (LESP) of elderly group was lower than that of control group ( 13.36 ±6.39 vs.15.57 ±7.01,P =0.009).Conclusion In comparison with young and middle-aged patients,the elderly GERD patients have lower esophageal motility,longer esophageal acid exposure time and higher frequency of severer esophagitis.

Objective: To study the correlation between angiotensin II type1 receptor autoantibodies (AT1-AAs) and the onset risk in patients with essential hypertension (EH) combiningacute coronary syndrome (ACS). Methods: Our research included in 4 groups: EH+ACS group,n=28, ACS group, n=29, EH group,n=26 and Control group,n=23 normal subjects. Serum levels of AT1-AAs were examined by ELISA; high sensitivity C-reactive protein (hs-CRP), blood levels of lipids and glucose were also measured and compared among different groups. The correlations between AT1-AAs and blood lipids, glucose, hs-CRP were studied by multiple linear regression analysis. Results: Compared with Control group, ACS group had similar level of AT1-AAs (0.26±0.09) vs (0.21±0.06),P=0.105; while EH+ACS group and HE group had increased AT1-AAs level as (0.40±0.005) and (0.33±0.10),P=0.001 andP=0.02 respectively; AT1-AAs level was higher in EH+ACS group than HE group,P=0.044. In addition, serum AT1-AAs level was positively related to hs-CRP in EH+ACS group, ACS group and EH group (r=0.589,r=0.503 andr=0.273, allP<0.01). Conclusion: Serum AT1-AAs level was positively related to the onset risk in patients with EH combining ACS; AT1-AAs was also related to hs-CRP at certain degree.

Objective To analyze hepatitis B virus ( HBV)-specific T lymphocyte responses dur-ing different stages of HBV infection.Methods Eighty-four patients with HBV infection were recruited in this study.They were divided into four groups including acute HBV infection group (8 cases), chronic HBV infection group (39 cases), hepatocirrhosis group (17 cases) and hepatocellular carcinoma group (20 ca-ses) .HBV-specific T cell responses were detected by using ELISPOT assay in combination with magnetic beads sorting assay.Results (1)The magnitudes of HBV-specific T cell responses in patients with acute HBV infection ,chronic HBV infection , hepatocirrhosis and hepatocellular carcinoma were respectively (2067.00±1029.00) SFU/106 PBMCs, (288.50±57.69) SFU/106 PBMCs, (96.25±31.06) SFU/106 PBMCs and (71.47±14.26) SFU/106 PBMCs.The differences with the magnitudes of HBV-specific T cell responses among patients from the four groups were significant (P<0.01).(2)HBV Core (HBV C) protein induced the strongest T cell responses[ (323.90±130.30) SFU/106 PBMCs] in patients with acute HBV infection in comparison with HBV-surface ( HBV S ) protein, HBV P protein and HBV X protein ( P=0.0037).The strongest T cell responses in patients with chronic HBV infection were induced by using HBV P protein [(127.20±54.42) SFU/106 PBMCs], followed by using HBV S protein, HBV C protein and HBV X protein (P=0.0159).(3)The magnitudes of IFN-γreleasing induced by HBV X protein, HBV P protein, HBV S protein and HBV C protein showed no significant differences in patients with either hepato-cirrhosis or hepatocellular carcinoma, but were lower than those induced in patients with chronic HBV infec-tion.Conclusion HBV-specific T cell responses were gradually reduced along the progression of HBV in-fection from acute HBV infection to chronic HBV infection, liver cirrhosis and hepatocellular carcinoma.The HBV-specific T cell responses induced by viral proteins might play different roles in different stages of HBV infection.

Objective To analyse clinical application of hepatitis B virus core antibody(HBcAb)detected by using the chemilu-minescence microparticle immunoassay.Methods A total of 1 6 830 specimen with positive HBcAb detected by using the two pairs of semi-hepatitis test from January 2012 to November 2014 were collected,and divided into three groups according to the cut off in-dex(COI)of detection results of HBcAb,including group 1.0-<9.0,group 9.0-<1 1.0 and group COI≥1 1.0,and detection re-sults were statistically analysed.The hepatitis B virus(HBV)DNA test was carried out in specimen with negative hepatitis B surface antigen(HBsAg)and hepatitis B surface antibody (HBsAb)and COI≥1 1.0.Results The detection rate of HBsAg(+)HBsAb(-) (13.84%)was significantly higher than other expression patterns in group ≥1 1.0(P <0.05).There was no statistically significant differences in positive rate among all expression patterns of HBsAg and HBsAb in the group 9.0-<1 1.0(P >0.05).The detec-tion rate of HBsAg(+)HBsAb(-)of group 9.0-<1 1.0 was significantly lower than that of the other two groups(P <0.05).A total of 304 specimen were HBsAg(-)HBsAb(-)and COI≥1 1,among them 64 specimen were HBV DNA postive and the posi-tive rate was 21.0%.Conclusion In the detection of HBcAb,COI≥1 1 and 1.0-<9.0 could be reference indicators for diagnosiing current and past HBV infection respectively,which should be combined with other laboratory indicators of HBV clinical data for comprehensive analysis.

Objective To explore the effect of lipid raft on cervical cancer cell growth and its mechanisms Methods HeLa cells in logarithmic phase were divided into three groups including control group, lipid raft interference agent group,and NADPH oxidase inhibitors group.Cells were treated with fre sh medium,3 μmol/L Apocynin and 1 mmol/L M-beta CD, respectively, for 24 h.Cell survival rate was detected using the MTT method, and the HIF-1α level was examined by Western-blot. Results Cell growths of the lipid raft interference agent group and NADPH oxidase inhibitors group were significantly slower than control group,(0.612±0.051 vs 0.984±0.034,0.591 ±0.074 vs 0.984±0.034,t=4.062,P＜0.05).HIF-1α expression in the lipid raft interference agent group and NADPH oxidase inhibitors group was also significantly reduced compared with control group (1.79±0.14 vs 2.56±0.22 and 1.54±0.12 vs 2.56±0.22) and the difference was significant (t=2.423,P＜0.05). Conclusion Lipid raft-NADPH oxidase pathway may activate HIF-1α and downstream protocarcinogenic gene expression to promote the growth of cervical cancer cells. The inhibitors of lipid raft and NADPH oxidase may become a new research direction for cervical cancer chemotherapy.

Objective To determine the ameliorative effects of Junzhi beverageⅠon neurobehavioral functions in subjects exposed to long-term sustained work.Methods Forty male students of a military institution were randomized into control group ( n=20 ) and the intervention group ( n=20 ) .All the subjects were exposed to 10-hours′high intensity mental work continuously (8∶00-18∶00).At 12∶50, the intervention group drunk a bottle of water with Junzhi beverageⅠ, but the control group drunk water of the same volume only.At 17∶00, neurobehavioral functions of all the subjects were tested by neurobehavioral core test battery (WHO-NCTB) and attention span test(AST).Results According to the results of WHO-NCBT, after 10-hours′continuous mental work,the profile of mood state in the intervention group was more stable than in the control group with lower scores in negative mood and higher scores in positive mood.Meanwhile, some of the neurobehavioral indexes were also found to be significantly improved, including shortened mean time of simple reaction and decreased error reaction rate, enhanced digit span backward, higher scores in Beton test , digit symbol test, Santa Ana practice hand and correct dot number (P<0.05).In addition, higher scores were obtained in the intervention group in AST(P<0.05).Conclusion Junzhi beverageⅠ can significantly improve the neurobehavioral function under sustained mental work conditions, which suggests that the beverage has the potential to postpone mental fatigue protect and enhance cognitive function.
