Objective To assess the effects on volume of uterine and the dominant fibroid by a re-new radiofrequency ablation ( RFA ) on uterine myomas and disemboweling them from uterine after RFA . Methods Three hundred and eight -three patients were treated by RFA and followed up at 1, 3, 6 and 12 months,165 of them by usual RFA , 163 by improved RFA.To them which myomas diameters were >5cm, 55 cases were added by disemboweling the myomas out of the body after one month of improved RFA .But 66 were not disemboweled.The pre-and postoperative uterine and myoma volumes were measured by 3D ul-trasonography .Results The volume of uterine and the dominant fibroid were reduced in usual and im-proved RFA groups , especially in improved group ,but the difference was no significantly ( P >0.05 ) .In the groups of which myomas diameters were >5cm , the median reduction rates of uterine and myoma vol-ume was more significantly in disemboweling group than un -disemboweling one after 3 and 6 months ( P <0.05 , P <0.01 ) .The overall effective rates were 90.90%,93.25%,100%and92.42%respectively in u-sual and improved RFA groups( P >0.05),and in disemboweling and un -disemboweling groups ( P >0.05).But the obvious effective rates have significant difference in disemboweling (81.82%)and un-dis-embowelin(41.94%)group ( P <0.01).Conclusion Disemboweling myomas from uterine after RFA can increase the clinical effects significantly .

Objective To evaluate the clinical application of intraluminal stent angioplasty(PTRAS) in the treatment of renal arterial stenoses. Methods A retrospective study was done in 28 patients with renal arterial stenoses. Primary renal artery stenting was performed in 28 consecutive patients (36 renal arteries). Blood pressure, serum creatine, the number of anti hypertensive medications were recorded at 1,6,12 month post stent angioplasty respectively. Arterial angiography was also taken 1 year later to evaluate the incidence of restenosis. Results Technical success rate was 100% achiving in all patients without serious complications. Primary successful patenty rate reached 82% (renal artery 86%), secondary successful rate was 89% (renal artery 90%). Systolic and diastolic blood pressure were reduced significantly ( P

Objective To investigate clinical effect of sIgA combined with Jiawei Yuping Feng pulvis in treatment of upper respiratory infection ( URI) in children.Methods 160 children in hospital diagnosed with URI were randomly divided into treatment group and control group.With basic treatment, the control group were treated with Jiawei Yuping Feng pulvis, twice per day, 3 g each time, orally; treatment group on the basis of control group, secretory IgA via nasal drip, 0.3-0.5 mg/( kg? d) , dividing into 6-8 times.The treatment course was 7 days.The total efficiency, improvement of symptoms and adverse reactions were observed and compared.Results The total effective rate of treatment group (96.25%) was significantly higher than control group (85%)(χ2 =5.96, P<0.05).After 7 days of treatment, WBC and NEUT% of treatment group decreased significantly compared with control group ( P <0.05 ) .The fever, sore throat and runny nose, cough and expectoration symptom remission time of treatment group were significantly shorter than control group (P<0.05).Adverse reactions of both groups were lower.Conclusion It is effective to treat URI in children using sIgA combined with Jiawei Yuping Feng pulvis therapy, and it has few adverse reactions.

Objective To study whether the uremic toxins accumulated long-term in uremia patients may be involved in oxidation of protein by forming advanced oxidative protein products (AOPPs). Methods Malonylaldehyde (MDA), hippuric acid (HA) and p-cresol were used as the representatives of uremic toxins. Human albumin serum (HSA), plasma specimens from normal or uremia patients were incubated respectively with MDA (10 retool/L), HA (20 mmol/L) and p-cresol (10 retool/L) or PBS (20 retool/L, pH 7.4, as control groups) at 37℃ for 30 minutes or 24 hours, respectively. Those indices such as AOPPs, protein thiol groups (Pt-SH) and dityrosine were used as biomarkers of protein injury. High performance liquid chromatography (HPLC) was employed to identify the aggregation and cross-links of modified proteins. Results AOPPs levels in all groups containing poison compounds were significantly increased by 121.5%(P<0.05) compared to that in control groups. Uremic toxins also resulted in over 14.7% loss in Pt-SH (P< 0.05) and 119.2% increment in dityrosine, respectively (P<0.05). Meanwhile, the formation of HMW-AOPPs in a time-dependent manner was observed by HPLC and cross-linked protein levels were significantly increased by 148.45%～333.3% in comparison with control groups. Conclusion Uremic toxins can directly mediate the damage of proteins by inducing the formation of HMW- AOPPs in a time-dependent manner, which is also one of the mechanism of AOPPs production in vivo besides the activation of the myeloperoxidase-H2O2-Cl pathway.

Objective To investigate the expression of Survivin,receptor for advanced glycation endproduct(RAGE) and high mobility group protein B1 (HMGB1) gene in human breast cancer and their clinical significance.Methods The expression of Survivin,RAGE and HMGB1 gene was detected by Real-time PCR technology and fluorescence in situ hybridization (FISH) technology in the following tissue samples:50 early breast cancers,50 advanced breast cancers,and the corresponding adjacent normal mammary tissues.The relationship of their expression and several factors such as differentiation degree,invasion,lymph node metastasis and TNM stage of cancer was explored.Results The positive expression rate of Survivin,RAGE and HMGB1 gene was 62％,73％ and 79％ detected by Real-time PCR technology,78％,69％ and 72％ detected by FISH technology in breast cancer tissues.The overexpression of these genes was positively correlated with TNM stage and lymph node metastasis.The expression of Survivin gene was positively correlated with the expression of RAGE and HMGB1.Conclusion Overexpression of Survivin,RAGE and HMGB1 gene is of great significance in early diagnosis and prognosis of human breast cancer.

Objective To study the effect of oxidative modification of hydrochlorous acid (HOCl) on human serum albumin (HSA) and the relationship between the AOPPs and HOCl-treated HSA. Methods Purified HSA (60 mg/ml) was treated with HOCl (0, 1, 5, 10, 20, 30, 40, 50 and 60 mmol/L). Size-exclusion chromatography was applied to estimate molecular weights of oxidized products of HSA by HOCl and spectrum scan from 190 nm -400 nm was performed to observe the spectrum characteristics of all variants of HSA. Results Major products of HSA after exposure to HOC1 were dimer and hexmer of HSA. The first-order process could be employed to describe the oxidative dynamics of monomer and dimer of HSA oxidized by HOCl. To AOPPs formation mediated by oxidant was identified as pseudo first-order reaction. However, formation hexmer was much in accordance with second-order reaction. Hexmer was also a major contributor to AOPPs in all types of modified HSA. Spectral analysis showed that red shift of absorbance maximum of polymers of HSA occurred, suggesting that a possibility that polymers of HSA were cross linked by tyrosine residues in protein. Conclusions Protein aggregation is primary consequence of HSA after its exposure to HOCl. Hexmer of HSA is the major contributor to AOPPs.
