0.05).Conclusions The ?2AR Gly16Gly genetic polymorphism was correlated with asthma severity and may be one of susceptibility genes in severe asthmatic children in Shanghai area.

This paper is to survey two groups of medicine-oriented English major undergraduates who have their probation either before or after the Quality Monitoring System is introduced to them about their degrees of learning satisfaction through questionnaires and seminar discussions. As a result, it proves that the implementation of the Quality Monitoring System in student probation helps to raise the degrees of student learning satisfaction, which clearly promotes the probation quality and secures the fulfillment of the mission in practice.

Objective To histomorphometricly assess changes occurred in the alveolar ridge following different methods of socket preservation and to compare them against natural healing without interventions. Methods The second、 third and fourth mandibular premolars were extracted from six beagles. Six extraction sites in each dog were randomly assigned to three treatments as follows:natural healing (T1), Bio-Oss Collagen (T2) and immediate implant with Bio-Oss (T3). Six month after surgery, the dogs were euthanized and tissue samples were sectioned, fixed and mounted, then were stained with toluidine blue. The histologic studies and morphological measurements were performed by using an optical microscope and a digital image software. Results Reabsorption in the buccal aspect of the alveolar crest of ridge was showed in all groups. With respect to the mean vertical bone loss of the buccal bone plate, T3 is lower than T1 and T2(P<0.001 ), while no significant differences were observed between T1 and T2. With regard to horizontal dimension of the alveolar process , a statistical significance could be found at 3mm and 4mm below the crest of ridge in group T1 and T3(P=0.017, P=0.042), while no statistical differences were found between other groups. Conclusions Both techniques of alveolar ridge preservation were not able to completely preserve the original bone volume after tooth extraction. Immediate implant placement in combination with Bio-Oss seems to have the potential to limit the reabsorption of the alveolar process efficiently , but the bone preserving effect of Bio-Oss Collagen is undesirable.

Objective To explore the mutations of hepatocellular carcinoma (HCC)-related hepatitis B virus (HBV) during mother-to-child transmission. so as to provide theoretic evidence for prophylaxis of HCC from the very beginning. Methods A total of 413 HBsAg-positive mothers and their newborns were enrolled in this study. Serum HBV DNA levels in maternal peripheral blood and cord blood of the newborns were measured using real-time quantitative PCR. Nested PCR together with cloning and sequencing methods were applied to examine the HCC-related HBV mutations in the preS and basal core promoter regions of HBV genome. All the newborns received standard HBV vaccination. Of the 413 newborns. 104 were successfully followed-up 7 months after birth. and the HBV mutations were examined if their circulating HBV DNA was detectable. Results Of the 413 newborns. 41 (9. 9%) had HBV DNA level >10³ copies/mL in their cord blood. Four (3. 8%) of the 104 newborns who were successfully followed up had circulating HBV DNA level >10³ copies/mL 7 months after birth. Compared to mothers without HBV trans-placental transmission. those with HBV trans-placental transmission had no increase in HBV mutations in the basal core promoter region. However. the viral mutations containing T2898G/C. C3000T. C3116T. T31C • and T52C in the preS region of HBV subgenotype C2 significantly increased the risk of HBV trans-placental transmission 8<0. 05). The frequencies of the HCC-related mutations in the preS and basal core promoter regions of HBV genome were not significantly different between maternal peripheral blood and the cord blood of the newborns. Importantly. the HCC-related mutations were rarely found in the HBV-positive infants at 7 months after birth. Conclusion The HBV mutations in the preS region of HBV subgenotype C2 may affect the trans-placental transmission of HBV. However, the quasispecies of HCC-related HBV mutants have no advantage in causing chronic HBV infection in infants. The HBV mutants which can promote HCC are selected during the long term chronic infection.

Objective: To study the transmission of hepatitis B virus (HBV) from mother to child and the related influencing factors, so as to provide evidence for HBV control. Methods: An epidemiological survey was conducted on 445 mother-infant pair participants with positive maternal HBsAg from 4 hospitals in Pudong New area of Shanghai. Peripheral blood samples of mothers and the umbilical cord blood samples of the infants were collected to detect the markers and DNA titer of HBV. HBsAg positive and HBV DNA positive in umbilical cord blood were defined as HBV positive in the infants. All the newborns received vaccination after birth according to the national regulation. Of the 445 participants, 104 newborns were followed for 7 months after birth, and the blood samples were collected and the markers and DNA titer of HBV were examined. HBsAg positive after 7 months was defined as immune failure. Results: The positive rate of HBV in the newborns was 8. 0% for mothers with positive HBsAg in our study. The HBV positive rate of newborns whose mothers were positive for both HBsAg and HBeAg was significantly higher than whose mothers were only HBsAg positive (26. 7% vs 1.8%, P<0. 05). The HBV positive rate was significantly higher in newborns whose mothers with HBV DNA >106 copies/mL compared with those with HBV DNA <106 copies/mL (23. 6% vs 2. 3%, P<0. 05). The immune failure rate of hepatitis B vaccine was 3. 8% 7 months after birth in our study, with all their mothers being positive for both HBsAg and HBeAg. Conclusion: The maternal HBeAg positivity and the high concentration of HBV DNA are the main risk factors of neonatal infection, and they may lead to non-response to hepatitis B vaccine.

Objective To discuss the clinical manifestations and CT findings of eosinophilic cystitis in chidren.Methods Nine cases including Six boys and 3 girls,three to 13 years old,mean age of 8.3- year,have symptoms of hematuria,irritative voiding,dysuria and abdominal pain。The eosinophilic cystitis was pathologically proved in 7 patients and eosinophilic granulomatous cystitis in 2 patients,which based on cystoscopic tissue biopsy or surgery retrospectively.Results Local thickened bladder walls or nodular and sessile masses along the bladder dome showed in four cases with eosinophilic granulomatous cystitis,and the diffusely irregularly thickened bladder walls showed on CT scans in the rest 5 cases with eosinophilic cystitis.Conclusion CT findings are helpful to reveal the site,size and other features of eosinophilic cystitis in children.But biopsy of the lesion is necessary to rule out other bladder tumor and selecting the proper management.

OBJECTIVETo investigate the effectiveness of pimecrolimus cream 1% for sensitive skin in adult women and its underlying mechanisms.

METHODSThe changes of subjective symptoms and signs were evaluated before and after the application of pimecrolimus cream 1% based on the severity of pruritus (SP) and severity of burning sensation (SB) scores, and on a basic syntax and molecular substrate (molecular psychophysics) of nociception and proprioception established by temperature-sensitive transient receptor potential (TRP) channels.

RESULTSThe SP and SB scores were significantly decreased in 32 patients with sensitive skin after using topical pimecrolimus cream 1% (P<0.05). Twenty (62.5%) patients showed positive capsaicin-like response (i.e. burning with consequent rapid amelioration of pruritus or burning sensation) and 6 (18.8%) showed positive camphor-like response (i.e. warming with consequent rapid amelioration of pruritus) on application sites after using the topical pimecrolimus cream 1%, and 6 (18.8%) showed negative capsaicin-like response and/or negative camphor-like response.

CONCLUSIONSPimecrolimus may rapidly inhibit or alleviate itch or burning sensation of patients with sensitive skin. The therapeutic effect of pimecrolimus is relevant to the mechanisms that activate or sensitize transient receptor potential vanilloid 1 (TRPV1) and desensitizes TRPV1 in the skin sensory afferents.

OBJECTIVETo explore the effect of Xinfeng Capsule (XC) on lipoprotein metabolism of rheumatoid arthritis (RA) patients.

METHODSTotally 180 RA patients were assigned to the experimental group and the control group by random digit table, 90 in each group. Patients in the experimental group took XC (three pills each time, three times daily), while those in the control group took Methotrexate Tablet (four tablets each time, once per week). One month consisted of one therapeutic course and all patients were treated for two therapeutic courses. A healthy control group consisting of 60 patients was also set up. Changes of lipoprotein indices, clinical efficacy, lipid metabolism, joint symptoms and signs, activity indicators were observed, and correlation analyses were performed.

RESULTSCompared with the healthy control group, expression levels of prealbumin (PA), globulin (GLO), high-density lipoprotein (HDL), apolipoprotein Al (Apo-A1) were lowered in RA patients (P <0. 05, P <0. 01). Correlation analyses showed that PA was negatively correlated with joint tenderness, morning stiffness time, disease activity score (DAS-28), C-reactive protein (CRP), interleukin (IL)-6, respectively. Total protein (TP) was negatively correlated with joint tenderness. GLO was negatively correlated with joint tenderness and DAS-28. HDL was negatively correlated with erythrocyte sedimentation rate (ESR) and endothelin (ET)-1. Apo-Al was negatively correlated with joint pain; Apo-B was negatively correlated with CRP; LDL was negatively correlated with morning stiffness time (P <0. 05, P <0. 01). Compared with before treatment, expression levels of PA, HDL, Apo-A1 , Apo-B, and serum IL-10 contents increased, and expression levels of ESR, CRP, IL-6, ET-1 , joint pain, joint swelling, morning stiffness time, and DAS-28 decreased in the experimental group (P <0. 05, P <0. 01). PA increased more after treatment than before treatment in the control group (P <0. 01). There was statistical difference in joint symptoms (except joint tenderness) and activity indices (except ET-1) in the control group (P <0. 05, P <0. 01). Compared with the control group after treatment, PA and HDL increased, ET-1 and duration of morning stiffness decreased in the experimental group (all P <0. 05).

CONCLUSIONSLipoprotein metabolic disorder exists in RA patients, and it is associated with disease activity. XC could obviously improve lipoprotein metabolism and joint symptoms.
