This study examined the effect of astilbin on the proliferation of rat aortic smooth muscle cells (RASMCs) induced by angiotensin II (AngII) and explored the possible mechanisms. Cell proliferation model of RASMCs was induced by treatmente with AngII. Cells were randomly divided to 8 groups. Normally cultured VSMCs serves as blank control group; in AngII model group, cells were treated with AngII at 10(-7) mol/L; in three astilbin groups, cells were treated with 10, 15, 30 mg/L of astilbin; in three AngII+astilbin groups, cells were treated with AngII (at 10(-7) mol/L) and astilbin at 10, 15, 30 mg/L. Cell proliferation ability was detected by MTT method and the cell cycles and proliferation index were flow cytometrically determined. The expression of c-myc mRNA was assessed by using reverse transcription polymerase chain reaction (RT-PCR), and the expression of NF-κB in RASMCs was immunocytochemically observed. Our results showed that MTT metabolism in RASMCs in the basic and AngII stimulated situation was inhibited by astilbin, and the cells numbers of G(0)/G(1) phase were increased and that of G(2)/S phase were decreased markedly. Not only highly expression of c-myc gene stimulated by AngII could be inhibited by Astilbin significantly, but also the expression of NF-κB protein can be down regulated by Astilbin. We are led to conclude that astilbin astilbin can inhibit the AngII-mediated proliferation of RASMCs by blocking the transition of RASMCs from G(0)/G(1) phase to S phase and by down-regulating the expression of NF-κB, c-myc gene.

OBJECTIVE: Tonsillectomy is one of the most frequently applied operations in the ENT practice. This prospective study compared intraoperative records and postoperative clinical outcomes between adults and children patients following monopolar electrocautery tonsillectomy. METHOD: Forty adult patients and Forty children patients with histories of recurrent tonsillitis or hypertrophic tonsillitis were enrolled. Intraoperative parameters and postoperative outcomes were compared. RESULT: Children tonsillectomy with monopolar electrocautery was significantly faster to perform (P < 0.05), and produced significantly less intraoperative blood loss (P < 0.05), and faster to return to commencement of a regular diet (P < 0.05) than adults. Children tonsillectomy endured less postopera- tive pain within a week (P > 0.05) than adults, but there was no significant difference in pain on the 14th postoperative day in two groups. There was no obvious postoperative hemorrhage in two groups. There was no significant difference in postoperative tonsillar fossa healing and postoperative temperature between the groups. CONCLUSION Children and adults tonsillectomy with monopolar electrocautery had clinical characteristics respectively. Monopolar electrocautery tonsillectomy was safe and operated easily in both two groups.

OBJECTIVE: This retrospective study compared clinical manifestations of idiopathic sudden hearing loss between children and the elderly. METHOD: 44 pediatric patients and 76 elderly patients diagnosed with idiopathic sudden deafness in our clinic from December 2009 to September 2014 were enrolled. Different clinical parameters were compared. RESULT: The incidence of initially profound hearing loss was highest and mild hearing loss was lowest in both groups (P < 0.05). There were no differences in the proportion with initially mild, moderate, severe, and profound hearing loss between both groups (P > 0.05). The number of patients was the most in initially profound type of audiogram pattern and the fewest in ascending type in both groups (P < 0.05). Hearing recovery rates in children (27/44, 61.4%) was higher than that in elderly patients (32/76, 42.1%) (P < 0.05). There were no differences in hearing recovery rates of the patients with initially level of hearing loss in both groups (P > 0.05). The highest recovery rate in children was in those with descending type and the lowest was in those with profound type (P < 0.05). There were no differences in hearing recovery rates in elderly patients with initially different types of audiogram pattern (P > 0.05). Hearing recovery rates of descending type in children were higher than that in elderly patients. Presence of tinnitus in pediatric patients was not relavent to the outcome (P > 0.05). Presence of tinnitus in elderly patients was associated with favorable outcomes. (P < 0.05). Presence of dizziness in pediatric patients was not relavent to the outcome (P > 0.05). Presence of dizziness in elderly patients was associated with poor outcomes (P < 0.05). Presence of initially different degrees of opposite side hearing loss in elderly patients was not relavent to the outcome (P > 0.05). Presence of chronic diseases in elderly patients was not associated with the outcome (P > 0.05). CONCLUSION The clinical manifestion of idiopathic sudden deafness is respective in Children and in elderly patients.

Objective To investigate the safty and proper concentration of using the sufentanil combined with ropivacaine in patient-controlled epidural analgesia (PCEA) under lower limb surgery in elderly. Methods Eighty patients scheduled for lower limb surgery were divided into 4 groups by random digits table with 20 cases in each. The concentration of the sufentanil were 0.1,0.2,0.3 and 0.4 μ g/ml in group A, B, C, D respectively. The concentration of the ropivacaine were 0.125% in each group for the PCEA.R-VAS, C-VAS , Bromage score, Ramsay score, press times ,dosage and side effects were monitored and recorded at 4,10,24 and 48 h after operation. Results Compared with those in group C, D, C-VAS,dosage of the analgesia,press times of PCEA were higher in group A,B (P＜0.01 or ＜ 0.05),the efficacy of press was lower in group A, B(P＜0.05), but there was no significant difference between group C and group D(P＞0.05 ).The Ramsay score 10,24 h after operation in group D[(4.5 ± 0.5 ), (4.6 ± 0.6) scores] was higher than that in group A,B,C [(2.7 ±0.8), (2.7 ±0.8) scores vs.(2.9 ± 0.9), (2.7 ± 0.9) scores vs. (3.0 ±0.7), (2.9 ±0.5) scores] (P ＜0.05). There were no case with hypotension and respiratory depression.Conclusion PCEA of four methods are safe and effective in elderly which 0.3 μ g/ml sufentanil combined with 0.125% ropivacaine have good analgesic effect and less side effect.

Objective To investigate the association between serum ferritin(SF) level at early and mid trimester of pregnancy and gestational diabetes mellitus (GDM) and insulin resistance (IR).Methods A total of 192 cases of women who were accepted antenatal examination from the first trimester of pregnancy at Yueqing People Hospital from July,2012 to October,2013 was prospectively analyzed and followed up.All cases were divided into two groups:96 cases of GDM pregnant women who were diagnosed as GDM at mid trimester of pregnancy as GDM group,and 96 cases of pregnant women with normal glucose tolerance at the same time as the control,normal glucose tolerance (NGT group).The differences in clinical data were compared between two groups.The relationship between SF level and fasting plasma glucose (FPG),fasting insulin (FINS),homeostasis model assessment insulin resistance (HOMA-IR),and C-peptide was investigated with Spearman rank correlation analysis.The predictive values of SF and relative variables to GDM were calculated by receiver operating characteristic curve (ROC) or Logistic regression analysis.Results (1) There was statistically significant difference in body weight and body mass index (BMI) at prepregnancy and mid trimester of pregnancy,Hb,FPG,FINS,SF,and C-peptide at the first trimester of pregnancy,SF level and FPG and HOMA-IR and C-peptide at mid trimester of pregnancy between two groups (P ＜ 0.01 or P ＜ 0.05).(2) As showed by Spearman rank correlation analysis,there was statistical correlation between SF at mid trimester of pregnancy,and FPG,FINS,HOMA-IR and C-peptide (P ＜0.01 or P ＜ 0.05);while no statistical correlation was found between SF at the first trimester of pregnancy and the same factors above (P ＞ 0.05).(3) The area under the ROC curve of SF at mid trimester of pregnancy for GDM was 0.653.The sensitivity and specificity were 68.8％ and 59.4％ in predicting GDM at the cut-off value of 16.61 ng/ml.As showed by Logistic regression analysis,high level of SF at mid trimester of pregnancy was a independent risk factor for GDM.Odds ratio (OR) was 1.032 (95％ CI:1.008 ～ 1.058,P ＜ 0.01).Conclusions The relationship between SF at different trimester of pregnancy and GDM is variant.There is relationship between high level SF of mid trimester of pregnancy in GDM pregnant women and IR.The level of SF might predict the occurrence of GDM.

Objective To observe the effects of combined generalepidural anesthesia on perioperative myocardial enzymogram and troponin T of the myocardium(cTnT)in old patients undergoing thoracic surgery.Methods Thirty-eight ASAⅠ-Ⅱ patients aged 60～80 years old were randomly divided into two groups.General anesthesia group(group G): anesthesia was induced with fentanly,propofol and vecuronium and maintained with isoflurane,propofol and vecuronium.Combined anesthesia group(group C):general anesthesia was performed as in group G and continuous epidural block with(1.6%) lidocaine was added during operation.Peripheral blood CK,CK-MB,AST,LDH and cTnT were measured before anesthesia,at the end of operation and at 6,24,48 hours after operation.Results Two groups could provide same postoperative analgesia.There was no change for HR,RR and MAP in two groups.Serum CK,AST,LDH and cTnT concentration in group G after operation were significantly higher than those before anesthesia(P

AIM: To investigate the effect of problem - based learning ( PBL) used in the teaching of medical students'evidence-based medicine ( EBM) .
METHODS: Five classes ( total 147 students ) were randomly selected as experimental ( PBL ) group, at the same time, another 5 classes ( total 149 students ) were also randomly selected as control group, using traditional teaching method ( lecture-based learning, LBL ) in 2010 grade. The final examination scores of the experimental group were compared with control at the end of term. In addition, all students were interviewed using self -administered questionnaire to obtain their evaluation for PBL practice. SPSS13. 0 software was used for statistical analysis.
RESULTS: The homogeneity test in baseline survey showed that the basic characteristics between the two groups of students were no significant differences, and were comparable (P>0. 05). Final exam results showed that in addition to the scores of the EBM basic knowledge indicated no significant difference between two groups of students (P>0. 05), for the 5 steps of EBM procedure, namely, asking questions, finding the best evidence, evaluating the evidence, using and practicing the evidence, re - evaluating the evidence, and the total scores between the two groups, there were significant statistically differences (P<0. 05). The results to student learning evaluation showed that there was no significant difference between the two groups (P>0. 05) in aspects of better understanding classroom knowledge, improving language expression ability, and writing skill exercises. And other residual items had a significant difference ( P<0. 05), especially in aspects of improving enthusiasm for learning, self - study ability, improving learning efficiency, information analysis and utilization ability, team collaboration, and communication between teachers and students, however, there was a very significant difference (P<0. 001) between the two groups.
CONCLUSION: PBL teaching mode can effectively improve teaching effectiveness and the quality of EBM teaching, so the this teaching mode is worth further popularizing.

Objectlve To investigate the inhibition of Coxsackievirus B3(CVB3)infection in cardiac myocytes cultured by small interfering RNA(siRNA)-mediated RNA interference and to evaluate the feasibility of siRNA as the prophylaxis and therapy for CVB3 infection.Methods Cardiac myocytes were prepared in vitro and infected with CVB3,and transfected with siRNA by lipofectamin and electroporation.The numbers of beating cardiac myocytes were counted under the microscope.Neutral red staining was used to evaluate the mortality of cardiac myocytes.Antiviral activities of these siRNAs were estimated by observing cytopathic effect(CPE),plaque reduction assay,Western blot assay and RT-PCR.Results siRNA-3753,which aimed at sequence in 2B section of CVB3 genome,displayed a stronger inhibition of CVB3 infection through screening in HeLa cells,siRNA-3753,chosen to transfect cultured neonatal mice cardiac myocytes,Wag observed to keep a good states of growing and beating at 24 h after CVB3 infection.Whereas the cytopathic signature of controlled cells became stopping beating,round and finally the cell fell off the culture plate.The results showed that siRNA-3753 could protect cells significantly,98.1%inhibition of CVB3 replication with electroporation transfection and 78.2%inhibition of CVB3 with liposome transfection.Transfection efficiencies were 56.0 3%and 9.0%by electroporation and lipofectamin,respectively.Conclusion siRNA,which aims at sequence in 2B section of CVB3 genome,can inhibit CVB3 infection in cultured cardiac myocytes.
