Objective To evaluate the curative effect,adverse reactions and complications of transcatheter uterine arterial embolization (TUAE) therapy for leiomyoma of uterus with three different embolization agents: silk particles, pingyangmycin-lipiodol emulsion (PLE), polyvinyl alcohol (PVA).Methods One hundred and twenty-six patients of uterus leiomyoma were included, who undergoing TUAE treatment with silk particles(54 cases, silk particles group) ,PLE(40 cases,PLE group) and PVA(32 cases, PVA group) respectively.Adverse reactions and complications were recorded until 6-60 months after TUAE treatment.Measured the volume of the leiomyoma by ultrasonic inspection or enhanced computed tomography (CT).Results All clinical symptoms of three groups were relieved, and the volumes of uterus leiomyoma after TUAE treatment of 6,12,24 months in PVA group [(50.84 ± 30.77), (39.92 ± 25.72), (31.24 ± 30.60) cm~3]were less than those in PLE group[(76.24 ± 31.16), (58.21 ± 32.05), (52.48 ± 31.41 ) cm~3]and silk particles group[(69.22 ± 36.22), (68.31 ± 32.42), (68.01 ± 30.12) cm~3].The inferior belly and perineal region pain were most slight in silk particles group, but no significant difference in complications was observed in three groups.The symptom recurrence was 3 cases, 2 cases in silk particles group and 1 case in PIE group.Conclusions Clinical outcome of TUAE treatment with all the three embolization agents is acceptable.Adverse reactions and complications are associated with volume of the leiomyoma and the area being embolized.PVA is superior in prevention of complications and relapse of uterus leiomyoma after TUAE treatment.

Objective To observe the effect of non-ablative treatment combined intense pulse light (IPL) and Q switched Nd :YAG laser on hyperpigmented skin diseases. Methods Total 250 cases of Fitzpatrick skin types Ⅲ and Ⅳ with hyperpigmented skin disorders received 4 treatments with combined 560nm IPI. and 532 nm Q switched Nd :YAG laser. The interval between two treat-ments was I month. After 3 months the effect of IPL was observed. If it was not good, we used the Q switched Nd :YAG laser. Efficacy and adverse effects were evaluated 3-6 months after the final treat-ment. Results 3-6 months after the last treatment, 50%-70% of patients had their telangiectasia, enlarged pores, hyperpigmentation and wrinking of facial photoaging improved. The degree of im-provement was more than 60 %. Common side effects were minor blistering and erythema. Conclusion Combined IPI. and Q switched Nd :YAG laser treatment is an idea non-ablative therapy for telangi-ectasia, enlarged pores, hyperpigmentation and wrinking of facial photoaging in Fitzpatrick skin types Ⅲ and Ⅳ in Asian.

Objective To explore the clinical effect and safety of methimazole combined with 131I in treatment of hyperthyroidism.Methods Patients (83 cases) with hyperthyroidism accepted in Xi'an Jiaotong University Affiliated San Er Ling Yi Hospital from June 2012 to June 2015 were selected and divided into observation group with 42 cases and control group with 41 cases.Patients in observation group were given methimazole combined with 131I,and patients in control group were given PTU combined with 131I.Then the clinical effect,thyroid gland serological indexes,adverse reations,and reoccurrence rates of two groups were observed and compared.Results The total clinical efficacy of observation group was 95.24％,which was obviously higher than 70.73％ of control group with statistically significance (P ＜ 0.05).TSH was getting higher after treatment of two groups,and T3,T4,FT3,FT4,TRAb,and TPOAb were getting lower after treatment of two groups.And TSH in the observation group was significantly higher than that in the control group,T3,T4,FT3,and FT4 were significantly lower than those in the control group (P ＜ 0.05).The adverse reaction rate of observation group (14.29％) was obviously lower than that of control group (46.34％) with statistically significance (P ＜ 0.05).The reoccurrence rate of observation group (4.76％) was obviously lower than that of control group (26.83％) with statistically significance(P ＜ 0.05).Conclusion Methimazole combined with 131I has good effect and safety in treatment of hyperthyroidism,which is worth of clinical application.

Objective To evaluate the significance of the expression level of aldo-keto reductase family 1 member C3(AKR1C3) for esophageal carcinoma patients treated with radiotherapy.Methods The clinical data of 28 patients with locally advanced esophageal carcinoma treated with radiotherapy alone was retrospectively analyzed, and the expression level of AKR1C3 was detected by immunohistochemistry.Statistical analysis was performed using SAS 8 statistical software, P<0.05 was considered statistically significant difference.Results The expression level of AKR1C3 was different in esophageal carcinoma patients at different levels of differentiation.The level of AKR1C3 expression was negatively correlated with efficacy of radiotherapy (P=0.031, 95%CI 0.151-0.914).Conclusion AKR1C3 can serve as a promising biomarker of the efficacy of radiotherapy for esophageal cancer.

OBJECTIVE To study the imprinting status of H19 gene in normal villi tissue during the first trimester,and its relation to the invasion of trophoblast. METHODS Using PCR-RFLP methods to examine the imprinting status of H19 gene in 93 cases of normal villi tissue during the first trimester. RESULTS Among 93 cases, heterozygous genotypes were found in 42 cases. And 11 cases of biallelic expression were found among these 42 cases of heterozygous genotypes from 5 to 9 weeks, however no biallelic expression existed from 10 to 12 weeks. CONCLUSIONS During the first trimester, H19 is expressed biallelically at the first 10 weeks. The H19 gene may dynamicly change in the trophoblast, and the dynamic change may have close relationship with the invasion of the trophoblast.

Objective To analyze the subtypes of eae genes in various non-O157 Shiga toxin-pro-ducing Escherichia coli ( STEC) strains isolated in China.Methods The complete nucleotide sequences of 10 eae genes were amplified by PCR and sequenced.The BLASTn software was used to analyze the se-quences for eae gene subtyping.A phylogenetic tree was constructed based on the10 ea e gene sequences to-gether with the gene sequences of 30 different subtypes in GenBank and those of STEC strains of 7 prevalent serotypes (O157 ∶H7, O26 ∶H11, O103 ∶H2, O111 ∶H8, O145 ∶H28, O45 ∶H2 and O121 ∶H19) using MEGA 5.0.Multilocus sequence typing (MLST) was performed on the 10 STEC strains with reference to the Escherichia coli ( E.coli) MLST website ( http://mlst.warwick.ac.uk/mlst/dbs/Ecoli) for the typing of multiple loci.A minimum spanning tree ( MST) was constructed using the BioNumerics software to inves-tigate the phylogenetic relationships between the 10 eae gene-positive STEC strains in this study and hemolyt-ic uremic syndrome-associated enterohemorrhagic E.coli ( HUSEC) strains as well as all human STEC strains of O157, O26, O45, O103, O111, O121 and O145 serotypes submitted to the E.coli MLST website data-base.Results The complete nucleotide sequences of eae genes in 10 non-O157 STEC strains were 2.8 kb in length and belonged to 3 known subtypes.The predominant subtype wasβ1, accounting for 60%of the 10 STEC strains (6/10), followed byθandγ1 subtypes with two strains in each type.The eae gene sequences in certain strains were identical to those of the prevalent serotypes.Seven sequence types ( STs) were identi-fied from the 10 STEC strains carrying eae gene.Conclusion The eae genes harbored by the non-O157 STEC strains isolated from different specimens in China were diverse and had close phylogenetic relationships with the highly pathogenic and prevalent STEC strains.This study implied that the STEC strains harboring eae gene had high pathogenic potential.

Objective To elucidate the clinical and pathological features, diagnosis, treatment and prognosis of nodal marginal zone B-cell lymphoma (NMZL). Methods 2 patients, with NMZL who has extremely elevated monoclonal IgM were analyzed and review were included. Results The common pathological diagnosis caused by the association of monoclonal gammopathy with indolent B-cell non-Hodgkin lymphomas was marginal zone lymphoma or B small cell lymphocytic lymphoma/B-cell chronic lymphocytic leukemia. According to our cases and literatures, the main distribution of involved sites in NMZL were lymph nodes, spleen and bone marrow. Sixty percent of the NMZL patients presented with advanced stage with, high risk of IPI. The diagnosis of NMZL was based on pathology of the lymph node. The proliferation and distribution of the differentiation monocytoid cell had a specified significance. Prognosis of early stage ( I or Ⅱ) NMZL were much better than that of advanced stage NMZL even the patients had received chemotherapy.Conclusion NMZL mainly involved lymph nodes, bone marrow and spleen, sporadically associated with the elevated monoclonal IgM. Most of the NMZL patients presented with advanced stage.The prognoses were poor.

Objective: To investigate into the etiological factor,distribution of syndrome(patterns),pathogenesis features as well as the curative effects of small compound prescriptions of(Traditional) Chinese Medicine(TCM) in the treatment of acute stroke in stroke unit.Methods:(Cases) corresponding to diagnosis standards were randomly divided into control group(102 cases) and treatment group(156 cases).Conventional treatment methods were given to cases in control group.On the base of control group,small compound prescriptions were added to in treatment group,successively 14-21 days.The relation between types and time and TCM scale(TCMS),the NIH stroke scale(NIHSS) and Barthel index(BI) were observed in the two groups.Results: Stroke was age-related,the older,the more stroke patients.Stroke was closely related to hypertension.Ascending hyperactivity of liver yang was main type in the previous three days,this type(decreased) with the time going on.On the contrary,the type of wind phlegm and blood stasis was secondly main type in the previous three days,it increased with the time going on.Types of ascending hyperactivity of liver yang,wind phlegm and blood stasis as well as phlegm heat and constipation covered 95 per cent of all patients in the previous 21days.In the two groups,the mean scale of TCM and NIH decreased,and BI increased after treatment,this statistical difference could also be seen between the two groups.Conclusion: Excessive types are main types in the acute stage of stroke.Types of ascending hyperactivity of liver yang,wind phlegm and blood stasis as well as phlegm heat and constipation are its main types.Transferring of ascending hyperactivity of liver yang into endogenous wind may be trigger of reaction link of wind,fire,phlegm and blood stasis in TCM theory.Small compound prescriptions of TCM aiming to clearing away liver fire to stop wind,to activate blood for removing blood stasis and phlegm,to removing phlegm and heat from discharge can reduce scale of TCM and NIH,increase BI in the treatment of patients in stroke unit,which provide beneficial proofs for evaluation of effects of TCM.

Objective To investigate the correlation between obstructive sleep apnea syndrome(OSAS)with myocardial ischemia and arrhythmia.Methods To observe the occuring rate of premature beats and change of ST- segment,90 eases of OSAS patients were detected by the polysomnogram(PSG)and dynamic electrocardiogram at the same time.Results Total morbidity of myocardial ischemia was 32.2 % in OSAS patients,and it was 59.4 %, 15.8 %,20 % in serious,moderate and mild groups respectively.There was a statistically significant difference be- tween the three groups and the control group(P0.05).Conclusion As one of the risky factors of cardiovascular diseases,OSAS can induce myocardial ischemia and arrhythmia.

Objective To investigate the renal level of 1o-hydroxylase and the change of serum calcium in rats with severe acute pancreatitis,and their correlation.Methods Eighty male Wistar rats were randomly (random number) divided into two groups:sham operation group (SO group),severe acute pancreatitis group (SAP group),and each group was further randomly divided into 1 h,3 h,6 h,and 12 h subgroups (n =10).Severe acute pancreatitis model was made by retrograde infusion with 5％ sodium taurocholate solution into the biliopancreatic duct,rats were sacrificed at 1 h,3 h,6 h,and 12 h separately after modeling.The levels of serum amylase,serum calcium,serum urea nitrogen,serum creatinine,serum 1,25-dihydroxy vitamin D3 were measured,and the level of lα-hydroxylase protein in the kidney was determined with immunohistochemistry and Western blotting.The histopathologic changes of kidney tissue were observed under light microscope and the changes of the proximal tubular epithelial cell were observed under electron microscope.Results Compared with SO group,the levels of serum amylase,serum urea nitrogen,and serum creatinine were higher in SAP group,but the levels of serum calcium and 1,25-dihydroxy vitamin D3 decreased at 3,6,and 12 h,and the renal level of 1 α-hydroxylase also decreased at 3,6,and 12 h after modeling.In SAP group,the levels of serum calcium,serum 1,25-dihydroxy vitamin D3 and the renal level of 1 α-hydroxylase gradually decreased,and the renal level of 1 α-hydroxylase and the level of serum 1,25-dihydroxy vitamin D3 had positive correlation at 3 h,6 h,and 12 h (r =0.93,P ＜0.01; r=0.951,P ＜0.01; r =0.92,P ＜0.01; r =0.878,P ＜0.01),and the renal level of 1α-hydroxylase and the level of serum calcium had positive correlation at 3 h,6 h,and 12 h (r =0.975,P ＜0.01; r=0.946,P＜0.01; r=0.747,P＜0.01).Conclusions Intheearly course of SAP,the lowered activity of 1 α-hydroxylase may play an important role in the development of hypocalcemia.
