Aim Toinvestigatetheeffectofbencyclo-quidium bromide(BCQB)on mucus MUC5AC expres-sion induced by lipopolysaccharide in cultured human nasalepithelialcells(HNECs).Methods Primary culture of human nasal epithelial cells (HNECs)was randomly divided into control group (C,with no treat-ment),LPS group (LPS,with LPS 1 mg · L-1 added in),BCQB low dose group(BCQBL,with LPS 1 mg· L-1 and BCQB 10 -8 mol·L-1 added in),BCQB mid-dle dose group(BCQBM,with LPS 1 mg·L-1 and BC-QB 10 -7 mol·L-1 added in),BCQB high dose group (BCQBH,with LPS 1 mg·L-1 and BCQB 10 -6 mol· L-1 added in)and ipratropium bromide group(IB,with LPS 1 mg·L-1 and IB 10 -6 mol·L-1 added in).Af-ter incubation at 37 ℃with 5% CO2 for 24 h,the ex-pression of MUC5 AC mRNA was detected with Real-time PCR and the expression of MUC5 AC protein in HNECs was detected with Western blot,while the ex-pression of MUC5 AC protein in supernatant was detec-tedwithELISAineachgroup.Results Ascompared with control group,the expression of MUC5 AC mRNA and protein increased significantly in LPS group (each P<0. 01 ).As compared with LPS group,the expres-sion of MUC5 AC mRNA and protein decreased signifi-cantly in each group of BCQB(P<0. 01,P<0. 05), and there was no statistical difference between BCQB high dose group and control group (each P>0. 05 ). Conclusion Bencycloquidiumbromidecansuppress MUC5 AC expression induced by LPS in cultured hu-man nasal epithelial cells,indicating that BCQB may be a new drug for nasal mucous hypersecretion diseases.

Objective To study the detection rate of early esophageal carcinoma using magnifying endoscopy,and to evaluate the relationship between the imaging patterns of microvasculature change and his- tological diagnosis.Methods Two hundred and fourteen patients with esophageal mucosa roughness,ero- sion,plaque,abnormal color and indentation in conventional endoscopy and 16 healthy volunteers were en- rolled.The magnifying endoscopy images were graded as four patterns by intraepithelial papillary capillary loop(IPCL)changes after iodine dyeing.The biopsies underwent pathologic evaluation.The comparison be- tween the imaging patterns of endoscopy and histological diagnosiswas was evaluated.Results 80.4%(90/ 112)esophagitis was type 2,and 85.7%(12/14)early esophageal carcinoma was type 3 and type 4.The difference was significant between early esophageal carcinoma and normal mueosa(?~2=27.32,P

Objective To explore the clinical characteristics and outcome of group B streptococcus (GBS) induced neonatal meningitis and to provide the guide for early diagnosis and appropriate treatment.Methods A retrospective chart review was performed.A total of 19 cases of neonatal purulent meningitis caused by GBS and 22 cases of neonatal purulent meningitis caused by Escherichia coli were identified in the NICU of Guangzhou Women and Children's Medical Center from Nov 1,2011 to Apr 31,2014.The clinical features,treatments and clinical turnover were analysed.Results GBS meningitis accounted for 24.7％ (19/77) of total bacterial positive cultures of blood or cerebral spinal fluid.The average time of progression to early-onset GBS meningitis of 6 early-onset cases mainly complaining of anhelation and groan,was (11.80 ± 11.34)h,and 83.3％ present within 24 hours;the main initial clinical symptoms of 13 late-onset cases[mean age (17.85 ± 7.77) d] were fever.Peripheral blood C-reactive protein concentration of GBS meningitis was significantly higher than that of Escherichia coli meningitis [(154.43 ± 88.64) mg/L vs.(67.52 ± 64.23) mg/L,P =0.001].Compared with Escherichia coli meningitis,the average length of stay in hospital and the recovery time of abnormal cerebral spinal fluid in neonates with GBS infection were both extended by more than 10 days.Conclusion The clinical manifestations of neonatal purulent meningitis caused by GBS are usually non-specific.It is associated with longer hospitalization and recovery time of abnormal cerebral spinal fluid.Antepartum prophylaxis,early diagnosis and therapy are vital for reducing the incidence of complications and mortality of neonatal GBS purulent meningitis.

Objective To investigate the nutrition status of the focus groups of iodine deficiency in the 5 coastal counties(districts)in Guangxi in 2008 to propose corresponding prevention and control measures.Methods In the 5 coastal counties(districts)in Guangxi,including Haicheng,Tieshangang,Yinhai districts and Hepu county in Beihai city,Qinnan district in Qinzhou city,the rates of iodized salt coverage,qualified iodized salt and consumption of qualified iodized salt had always been below the average level of Guangxi.In the study,6 towns were randomly picked in Hepu district,and 3 towns were randomly picked in each of the other 4 coastal counties(districts).Two administrative viRages were randomly picked in each town.Forty children ages 8 to 10 and 10 women of child-beating age from 18 to 42 which included 5 pregnant and lactating women,were picked from each administrative village.Arsenic-cerium catalyzed spectrophotometry(WS/T 107-2006)Was used to determine the urinary iodine.Results In total,1437 urine samples of the children Were picked.The median of the children's urinary iodine Was 191.0μg/L,with 1.4%(20/1437)of the children's urinary iodine<20 μg/L,and 5.4%(77/1437)<50 μg/L, and 20.3%(292/1437) < 100 μg/L. The medians of the children's urinary iodine were 134.5 - 220.0 μg/L.In Haicheng and Hepu, the medians of the children's urinary iodine were higher than 200 μg/L(220.0,209.5 μg/L, respectively). The medians of the children's urinary iodine in the other 3 counties(districts) were within the suitable range between 100 and 200 μg/L(134.5,162.4,199.3 μg/L, respectively). The medians of the 8- and 9-year-old ehildren's urinary iodine (192.3,206.7 μg/L, respectively) were higher than that of the 10-year-old children's(157.2 μg/L, χ2 = 19.644,41.997, all P < 0.017). Totally, 365 urine samples of the women were picked.The medians of the women's urinary iodine in the 5 counties were 88.2 - 195.6 μg/L, with 195.6 μg/L in Haicheng and 156.5 μg/L in Hepu, and 88.2 μg/L in Tieshangang, which was the lowest and below 100 μg/L. The median of the childbearing-age women's urinary iodine was the highest(152.6 μg/L). The median of the lactating women's urinary iodine was the second (131.9 μg/L). The median of the pregnant women's urinary iodine was the lowest (89.4 μg/L) and below 100 μg/L. Only 6.7%(2/30) of the pregnant women's urinary iodine were within the suitable range between 150 and 250 μg,/L. Conclusions In the 5 coastal counties(districts) in Guangxi, 8 to 10-year-old children had good nutrition levels while childbearing-age and lactating women were within the suitable range. As a whole, the pregnant women had insufficient iodine nutrition. We propose that the iodine nutritional status of pregnant women is monitored routinely, with further prevention, control measures, health publicity and education necessary to improve iodized salt coverage.

OBJECTIVETo observe the clinical effect of traditional Chinese medicine Bushen Houxue (BSHX) method combined with ultrasound-guided follicle aspiration (MFA) in treating refractory polycystic ovary syndrome (PCOS).

METHODSForty-four patients with PCOS were randomly assigned to two groups by randomizing digital table, 20 in the observation group and 24 in the control group. MFA was performed on both groups, and the decoction of BSHX, which consisted of dodder seed 20 g, prepared rehmannia root 10 g, mulberry mistletoe 20 g, epimedium 15 g, psoralea fruit 10 g, solomonseal rhizome 10 g, honeylocust thorn 15 g, peach kernel 10 g, pleione bulbocodioides 10 g, red sage root 20 g, and licorice root 6 g, was given to the observation group one dose every day for 14 days every menstrual cycle. Changes of follicle stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) were determined before and after MFA. The impacts on quantity of HMG used, number of sinus follicle, mature follicle, incidence of ovarian hyperstimulating syndrome (OHSS), luteinized unrupture follicular syndrome (LUFS) and pregnance rate were also observed.

RESULTSMFA had been performed for 42 cycles in the observation group and 56 cycles in the control group. Levels of T, LH and LH/FSH ratio markedly reduced after aspiration, showing significant difference as compared with those of before treatment in both groups (P < 0.01), and difference of LH/FSH between groups was of statistical significance (P <0.01). In the observation group, 18 patients (90.0%) had their sinus follicle decreased to < 10 after MFA, while in the control group, it reached to <10 in 22 patients (91.70%), all were different to those before treatment (P <0.01). In the observation group, the quantity of HMG used for promoting ovulation was (585.0 +/- 195.0) IU, number of mature follicle at the day of HCG injection was 1.1 +/- 0.3, while in the control group, the corresponding data were (1470.0 +/- 532.5) IU and 3.1 +/- 1.4, all with significant difference between groups (P <0.01). None of OHSS and 1 case of LUFS occurred in the former group, while 1 mild OHSS and 2 LUFS in the latter. After ovulation promoting therapy and in the 3-month secutive follow-up period, pregnancy was found in 8 out of the 18 patients in the observation group (one twins and 7 single), with the pregnancy rate of 44.4%; while in the control group, 7 in 22 (2 twins and 5 single) was found, the pregnancy rate being 31.8%.

CONCLUSIONBSHX method combined with MFA is a safe and effective treatment for refractory PCOS, with few trauma. The combined usage of Chinese herbal medicine could significantly reduce dosage of HMG used for promoting follicle and the production of multiple mature follicles, thus to avoid the risk of OHSS.

Objective To detect the levels of five trace elements in whole blood of patients with Keshan disease(KSD) and dilated cardiomyopathy(DCM) and explore their role in the pathogenesis of KSD.Methods One hundred and four patients with chronic KSD were selected from Keshan diseased areas in Shandong,Sichuan and Inner Mongolia.Thirty patients with DCM were selected from Qilu Hospital of Shandong University,Jinan Central Hospital,The First People's Hospital.Ninety-one healthy people from KSD endemic areas and 39 healthy people from Jinan were selected as endemic healthy controls and non-endemic healthy controls,respectively.Blood samples were collected to determinate the level of selenium (Se),copper (Cu),zinc (Zn),chromium (Cr) and manganese (Mn) with fluorescence method and atomic absorption spectrometry,according to the principle of informed consent.Results The level of Se,Zn and Cr of KSD group[(36.0 + 4.9)μg/L,(22.73 + 4.62)mg/L,(0.56 + 0.17)mg/L] was significantly lower than that of non-endemic healthy controls [(56.4 ± 6.8)lμg/L,(25.35 ± 4.44)mg/L,(0.71 ± 0.17)mg/L,all P ＜ 0.05],but the level of Cu of KSD group[(0.95 ± 0.24)mg/L] was significantly higher than that of non-endemic healthy controls[(0.73 ± 0.13) mg/L,all P ＜ 0.05].The level of Se and Cr of KSD was significantly lower than that of endemic healthy controls[(54.5 ± 5.4)μg/L,(0.87 ± 0.02)mg/L,P ＜ 0.05],and Cu was significantly higher than that of endemic healthy controls[(0.66 ± 0.02)mg/L,P ＜ 0.05].The level of Cu and Zn of KSD was significantly lower than that of DCM [(1.21 ± 0.23)mg/L,(27.09 ± 7.10)mg/L,all P ＜ 0.01].The level of Se and Cr of DCM group[(39.6 ± 3.5)μg/L,(0.58 ± 0.14)mg/L] was significantly lower than that of non-endemic healthy controls(all P ＜ 0.01),but Cu[(1.21 + 0.23)mg/L] was significantly increased (P ＜ 0.01).Compared with non-endemic healthy controls,the level of Se of endemic healthy control group was significantly decreased (P ＜ 0.01),while Cu was significantly increased (P ＜ 0.01).Se,Zn and Cr level of KSD decreased gradually following elevated heart function level,but the level of Cu gradually increased.Conclusions The metabolism of Se,Cr,Cu and Zn is unbalanced in KSD patients,whose Se level is still lower than that of people in non-endemic areas.The change of Se,Cr,Cu and Mn level between KSD and DCM is consistent.

Objective to compare and contrast the diagnosis results on 2D and 3D Ultrasonogrpahy against MRI. Method A 2D Ultrasonography was applied during a conventional prenatal sonography checking with a 3D Sonography assessment subsequently conducted to follow up on 49 fetus suspected of brain malformation.Furthermore, a MRI scan was taken within 24 hours after the 3D Sonography checking in our hospital as a final test. Data collections from all three assessments were completed, and an analysis of the comparisons of these three methods were done. Results Among these 49 fetus with confirmed or suspected brain malformation, there were two cases of misdiagnoses of Dandy-Walker Malformation assessed by 2D sonography, with a misdiagnosis rate of 40％, (P ＜ 0.05) indicating a statistically significant result; misdiagnosis rate of Fetal Ventriculomegaly and Isolated Broadening Posterior Fossa were calculated as 26.7％ and 33.3％ respectively (P ＜0.05), a statistically significant result. Overall, there were two cases with Cerebellum Malformation, from in which one case was identified by MRI, and the other one was misdiagnosed, with a misdiagnosis rate of 50.0％.In total, there were 2 cases of Holoprosencephaly, in which one was identified by Prenatal MRI, and the other was misdiagnosed (P ＜ 0.05), a statistically significant result. Conclusions All three assessments of 2D ultrasonography, 3D ultrasonography and MRI have their own advantages and disadvantages. In short, 2D Sonography is suggested to be applied for screening out cases with brain malformation, together with 3D Sonography as a complementary assessment. MRI can also be an effective and significant complement for sonography in completing and readdressing the final ultrasonic results.

The objective of this study was to investigate the efficacy and toxicity of standard-dose idarubicin in combination with continuous infusion of cytarabine as induction therapy in patients with acute myeloid leukemia (AML). A total of 38 AML patients were enrolled, including 30 new diagnosed patients, 8 relapsed and refractory patients. Cytogenetic analysis was performed in all patients, 15 patients had cytogenetic aberrations including 4 complex abnormalities. All patients were treated with standard-dose idarubicin [12 mg/(m(2).d), days 1 to 3] and continuous infusion of cytarabine [100 mg/(m(2).d), days 1 to 7]. The results showed that after one course of induction therapy, the overall response rate was 89.5% (34/38), and 32 out of 38 (84.2%) patients achieved complete remission (CR), including 27 of 30 (90.0%) new diagnosed AML patients, 5 (62.5%) refractory and relapsed AML patients, all 4 patients with complex cytogenetic aberrations achieved cytogenetic CR. Out of 6 relapsed patients 2 showed as extramedullary relapse, 4 showed as bone marrow relapse. The median survival duration was > 22 months and median disease-free survival time was > 16 months. Myelosuppression and infections due to neutropenia were the most frequent adverse effects, severe nonhematologic toxicity and the early death were not observed in the patients. It is concluded that standard-dose of idarubicin combined with continuous infusions of cytarabine as the induction therapy is highly effective and well tolerated approach in patients with AML, this regimen provides an opportune moment for hematopoietic stem cell transplantation.
