Objective To investigate the efficacy of interferon alpha (IFNα) plus adefovir dipivoxil (ADV) and tebivudine (LdT) monotherapy for patients with HBeAg positive chronic hepatitis B (CHB) who have poor response to IFNα treatment.Methods A total of 86 HBeAg positive CHB patients admitted to the Sixth People' s Hospital of Shaoxing during February 2010 and April 2013 were enrolled in the study.All the patients received IFNα monotherapy for 24 weeks and had poor responses.The patients were voluntarily divided into three groups:IFNα monotherapy group (n =21),IFNα plus ADV group (n =30) and LdT monotherapy group (n =35).Chi-square test was used to compare ALT normalization rates,rate of HBV DNA load ＜ 500 copies/mL,HBeAg seroconversion and HBsAg seroconversion rates among three groups.Results After 48 weeks of treatment,the ALT normalization rate in IFNα monotherapy group was 52.6％ (10/19),which was lower than those in IFNα plus ADV group (86.7％,26/30) and LdT monotherapy group (84.8％,28/33) (x2 =6.913 and 6.361,P ＜ 0.05).The rate of HBV DNA load ＜500 copies/mL in IFNα monotherapy group was 26.3％ (5/19),which was lower than those in IFNα plus ADV group (60.0％,18/30) and LdT monotherapy group (54.5％,18/33) (x2 =11.33 and 3.895,P ＜0.05).No HBeAg negative conversion or seroconversion was observed in IFNα monotherapy group,but it was observed in 6 (20.0％,6/30) patients in IFNαt plus ADV group and 7 (21.2％,7/33) patients in LdT monotherapy group (x2 =4.330 and 4.657,P ＜ 0.05).No HBsAg seroconversion was observed in three groups.There were no statistical significant differences in ALT normalization rates,rate of HBV DNA load ＜ 500 copies/mL,HBeAg seroconversion and HBsAg seroconversion rates between IFNαt plus ADV group and LdT monotherapy (x2 =0.042,0019 and 0.064,P ＞ 0.05).Conclusion For patients with HBeAg positive CHB who had poor response to IFNα treatment,IFNα plus ADV therapy and LdT monotherapy have the same efficacy in improvement of both liver function and virological response.

Guided by the antioxidant activity, the EtOAc-soluble and n-butanol-soluble fractions of the 50% methanol extract of Lonicera japonica leaves were isolated and purified by various chromatorgraphic methods, and the structures were identified by spectral analysis and comparison to the data reported in literature. As a result, nine compounds were obtained and identified as 5-O-caffeoylquinicacid (1), chlorogenicacid (2), 4-O-caffeoylquinicacid (3), luteolin-7-O-[α-L-arabinopyranosyl-(1 --> 6)] -β-D-glucopyranoside (4), luteoloside (5), 3,4-di-O-caffeoylquinic acid (6), 3,5-di-O-caffeoylquinic acid (7), 4, 5-di-O-caffeoylquinic acid (8) and luteolin (9). The antioxidant activity of the nine compounds were determined by using DPPH free radical scavenging method, and ascorbic acid was used as a positive control. Their antioxidant activities from high to low were 5 > 9 > 2 > 8 > 7 > 6 > 1 > 3 > 4. Among them, luteoloside (5) had the strongest antioxidant activity with an IC50 of 0.018 18 g x L(-1), and luteolin (IC50 0.023 6 g x L(-1)) and chlorogenicacid (IC50 0.035 17 g x L(-1)) ranks No. 2 and 3. Furthermore, the antioxidant activity of luteoloside and luteolin were stronger than that of ascorbic acid (IC50 0.027 54 g x L(-1)). These results gave a basis for the further study and utilization of L. japonica leaves.

Objective; To evaluate the influence of electrolyte's concentration at micro-arc oxide treatment on the bonding strength of titanium to porcelain. Methods; CP titanium specimens with size of 25 mm ×3 mm ×0. 5 mm were treated with micro-arc oxidation (MAO) in Na_2SiO_3 solution of three different concentrations. After ultra-low-fusing porcelain was applied, a three-point-flexure-test was used to evaluate the bonding strength of titanium to porcelain. The surface of the specimens was observed by SEM and EDS, as well as the interface between titanium and porcelain. Results; The bonding strength values between titanium treated with MAO and porcelain was significantly higher then the control groups, Croup 20 g/L has the highest bonding strength values. SEM/EDS suggested that a porous thin layer of oxide which contains Si element is created by MAO, and higher concentration of Na_2SiO_3 leads to more Si element in oxide. Conclusion; MAO treating can improve the bonding strength between titanium and ceramic. Electrolyte's concentration has an effect on the bond strength between titanium and porcelain.

Objective To investigate the impact and clinical significance of helicobacter pylori (Hp) elimination on ghrelin. Methods Forty patients with chronic superficial gastritis (CSG), 42 patients with chronic atrophic gastritis (CAG), 41 patients with peptic ulcer (PU) and 17 patients with gastric adenocarcinoma (CA) were included in this study. All of pa-tients in four groups were Hp-positive. Forty patients with Hp-negative were used as control. The Hp elimination were only performed in CAG,CSG and PU groups. The serum ghrelin and pepsinogen (PG) levels before and after Hp elimination were detected with ELISA assay in CSG, CAG and PU groups. The correlation between PG and glrelin was also detected. The ex-pression of ghrelin in gastric mucosa was detected by RT-PCR. Results Comparing with control group (30.41 ± 8.97), the ghrelin level was increased in PU group (35.42±9.87), but which were decreased in CAG group (18.59±8.19) and CA group (18.33±6.88). There was no significant difference in ghrelin level between CSG group (26.08±9.14) and control group. After Hp elimination, the serum and gastric mucosa ghrelin levels were significantly increased in CSG group (P＜0.01), but both serum and gastric mucosa ghrelin levels were significantly decreased in PU group (P＜0.01). And no significant difference in the level of ghrelin after Hp elimination in CAG group (P>0.05). A positive correlation was found between serum PGⅠ/PGⅡand serum ghrelin level in CSG, CAG and CA groups (r=0.668,P＜0.01). Conclusion Hp elimination has an impact on ghrelin level in patients with upper gastrointestinal diseases. The changes of ghrelin level related to PGⅠ/PGⅡ. Ghrelin can be used as one of the indexes of diagnostic and prognostic evaluation in Hp related upper gastrointestinal diseases.

OBJECTIVETo analyze the effect of Chinese herbs used by Prof. LI Tao on peripheral blood T subsets in treating multiple sclerosis (MS) by using association rules and statistical methods, thereby providing evidence for optimizing prescriptions.

METHODSData of MS inpatients and outpatients recorded by data collecting system, Xiyuan Hospital, China Academy of Chinese Medical Sciences were resorted. The relationship between Chinese herbs and T cell subsets were analyzed using SPSS17.0 and Aprior module in SPSS Clementine 12.0.

RESULTSRadix bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, and Radix Glycyrrhizae were most commonly used herbal combinations.Radix Aconiti lateralis preparata and Rhizoma Smilacis glabrae were often added. Radix Aconiti lateralis preparata was associated with decreased Th1 cells (confidence level 83.78%, supportive level 36.26%). Decreased Th1 cell was associated with Radix Aconiti lateralis preparata (confidence level 71.26%, supportive level 36.26%).Radix Aconiti lateralis preparata was obviously associated with decreased Th1 cells. Radix Bupleuri, Radix Paeoniae alba, bitter orange, Atractylodes , Radix glycyrrhizae, and Radix Aconiti lateralis preparata could reduce peripheral blood Th1 subsets of MS patients and elevate Th2 subsets (all P < 0.01).

CONCLUSIONSThe herbal combination of Radix Bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, Radix Glycyrrhizae, Rhizoma Smilacis glabrae, and Radix Aconiti lateralis preparata could lower peripheral blood Th1 cells and elevate Th2 cells, and prevent the relapse of MS possibly by reducing Th1 cells and elevating Th2 cells. Especially Radix Aconiti lateralis preparata played important roles in aforesaid changes of Th1 and Th2.

OBJECTIVEA study was conducted to investigate the relevant applied technique and clinical value of endoscope-assisted repair of zygomatic arch fracture.

METHODSA total of 10 cases of unilateral zygomatic arch fracture and 8 cases ofunilateral zygomatic fracture were included. Reduction and fixation of the zygomatic arch in all cases were performed via asmall face incision by an endoscope. Endoscope-assisted repair allowed exposure of zygomatic arch fracture and ended the anatomy of the reset. Zygomatic arch was stabilized with titanium plates.

RESULTSSymmetric malar was achieved in allcases after operation. Patients did not show difficulty in opening the mouth. No chewing problems or severe complicationswere evident. This method had the advantage of hidden incision, and it did not leave scars on the face. Postoperative CT examination showed excellent reduction of zygomatic arch fracture and good fixed position of titanium plate.

CONCLUSIONEndoscope-assisted repair of zygomatic arch fracture via a small face incision can be an alternative operation for zygomaticarch fracture. Patients are less traumatized. There are fewer complications. A good reduction of fracture is achieved.

Objective To investigate the serum cystatin C (CysC) level and explore its relationship with cytokines and atherosclerosis (AS) in maintenance hemodialysis (MHD) patients.Methods A total of 110 stable MHD patients undergoing hemodialysis for at least six months and 60 healthy control people were enrolled in the study.Serum levels of CysC and high-sensitivity Creactive protein (hsCRP) were measured by immunoturbidimetry.The serum levels of total homocysteine (tHcy),IL-1β,IL-6 and TNF-α were determined by ELISA.Prevalence of atherosclerosis was detected by carotid ultrasonography.The relationship of CysC level and cardiac geometry incidence in MHD patients was analyzed by Logistic regression model.Results The serum CysC level was significantly higher in MHD patients as compared with healthy controls [(6.19±0.95) mg/L vs (0.76±0.21) mg/L,P＜0.01],and the serum levels of hsCRP,tHcy,IL-1β,IL-6,TNF-α were significantly higher in MHD patients than those in healthy control group (P＜0.05 or P＜0.01).The serum CysC level was higher in MHD patients with carotid artery atherosclerosis compared to patients without carotid artery atherosclerosis (P＜0.05).CysC was positively correlated with hsCRP,tHcy,IL-1β,IL-6,TNF-α respectively (P＜0.05 or P＜O.01),and was positively correlated with carotid intimal medial thickness (IMT) and AS.Besides,a negative correlation was found between the serum CysC level and the serum albumin level (P＜0.05),while CysC was positively correlated with dialysis duration,systolic pressure and iPTH (P ＜0.05).Conclusion Serum CysC level is significantly higher in MHD patients and is correlated with hsCRP,tHcy,IL-1β,IL-6,TNF-α as well as carotid artery atherosclerosis,which indicates that CysC is an independent risk factor of AS in MHD patients.

Objective The vertical mammaplasty improves the breast morphology,and reduces the operative scar.However,the nipple-and-areola complex (NAC) has the risk of necrosis on those severe patients.In this report,we performed the vertical incision scar reduction mammaplasty based on Würinger's horizontal septum to reduce the NAC necrosis possibility.Methods Typical Lejour mosque-dome design was performed.The inferior part of glandular tissue and skin were excised.The NAC was elevated to normal position with medial-superior pedicle based on the horizontal septum.The breast morphology was modified with lateral and medial glandular pillar suturing using nonabsorbent thread.For reducing the vertical scar,the lower breast flap was thinned to induce the skin contraction.Results 27 patients with breast hypertrophy were operated from May 2009 to October 2012.1 patient had unilateral breast reduction,and 6 patients with 8 breasts had partial wound dehiscence.They were treated conservatively with topical dressings.No complete NAC necrosis occurred.Conclusions The vertical reduction mammaplasty based on Würinger's horizontal septum is a safe and effective approach,and the NAC necrosis possibility is reduced with this procedure.
