Objective To explore the diagnostic value of the quantitative detection of plasma miRNA-125b and miRNA-133b in children with asthma.Methods Thirty asthmatic patients were enrolled in this study and collected the blood specimens during acute phase and stable phase respectively (AP group and SP group).Thirty allergic rhinitis children (AR group) and thirty healthy children were recruited to the control group (NC group).The levels of miRNA in different groups were detected by qRT-PCR.The performance of miRNA-125b and miRNA-133b were evaluated by receiver operating characteristic curves (ROC) and the area under the curve (AUC) (95％CI).Results The relative expression of miRNA-125b in AP group and SP group were significantly higher than A R group (t=3.913,3.120,P＜0.01),miRNA-133b.In AP group and AR group the expression of miRNA-133b were significantly higher than control group (t=4.426,4.720,P＜0.01).The detection of miRNA-125b yielded an area under the curve of ROC of 0.7989,(95 ％ CI:0.7111～ 0.8864) in discriminating asthmatic patients from healthy group.And the miRNA-133b was 0.7274 (95％CI:0.586 5～0.863 0) in discriminating asthmatic patients during the acute phase from healthy group.Conclusion The relative expression of miRNA-125b in children with asthma was significantly higher than that in AR group and NC group,miRNA-125b may prove to be a non-invasive biomarker for the auxiliary diagnosis of asthma especially when the relative expression up to 1.998.

OBJECTIVETo explore efficacy enhancing and detoxification roles of Jiedu Quyu Zishen Recipe (JQZR) in treating systemic lupus erythematosus (SLE) by studying its effect on Toll like receptor 9 (TLR9) signal pathway of murine macrophage cells after JQZR stimulated CpG oligodeoxynucletide (CpG ODN).

METHODSMurine macrophage cells in vitro cultured were randomly divided into 4 groups, i.e., the blank serum group, the CpG ODN stimulus group, the CpG ODN + dexamethasone group, the CpG ODN + medicated serum group. Murine macrophage cells were collected after 24-h intervention. The expression of TLR9, myeloid differentiation factor 88 (MyD88), NF-KB, IFN-α mRNA were analyzed by RT-PCR. The expression of TLR9 and NF-κB protein were analyzed by Western blot. Changes of the NF-KB transcriptional activity were assayed by Dual-Luciferase reporter assay system.

RESULTSmRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were enhanced, showing statistical difference when compared with those of the blank serum group (P <0. 05, P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of MyD88, NF-κB, and IFN-α, the protein expression of NF-κB and the NF-κB transcriptional activities decreased in the CpG ODN + dexamethasone group with statistical difference (P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were decreased in CpG ODN+ medicated serum group with statistical difference (P <0. 01).

CONCLUSIONEfficacy enhancing and detoxification roles of JQZR in treatment of SLE might be realized through regulating TLR9 signal pathways.

Objective To summarize the ultrasonographic features and differential diagnosis of uterine cornual pregnancy.Methods Trans-abdominal and trans-vaginal ultrasound were performed in 93 uterine cornual pregnancy patients before surgery,ultrasonographic findings of uterine cornual pregnancy through different two approaches were analyzed and compared with surgical and pathologic findings.ResultsIn contrast with surgical and pathological diagnosis,66 cases(82.5%,66/80) of uterine cornual pregnancy were accurately diagnosed by ultrasonography before surgery,these cases were divided into gestational sac pattern (55 cases) and mixed mass pattern(11 cases); 11 cases were misdiagnosed as interstitial tubal pregnancy,2 cases were misdiagnosed as pregnancy in rudimentary horn,1 case was misdiagnosed as choriocarcinoma,misdiagnosed rate were 17.5%(14/80); uterine cornual pregnancy presented as adnexal mass in ultrasound in 13 cases,while ruptured uterine cornual mass were found in surgery,in which location and type of the masses couldn't be accurately diagnosed by ultrasound.Ultrasonographic features of uterine cornual pregnancy presented as a gestational sac located in extended cornual of uterus,surrounded by thin myometrium,and connected with endometrium.The misdiagnosed causes were: (1) Uterine cornual mass was not connected with endometrium or surrounded by thin myometrium,which were misdiagnosed as interstitial tubal pregnancy.(2) Uterine cornual pregnancy with thick lateral myometrium were misdiagnosed as pregnancy in rudimentary horn.(3)Uterine cornual pregnancy presented as cornual mass with abundant blood flow was misdiagnosed as choriocarcinoma.Conclusions Uterine cornual pregnancy can be accurately diagnosed by trans-abdominal and trans-vaginal ultrasound.Ultrasonographic features are helpful in differential diagnosis of uterine cornual pregnancy.

Objective To compare the odds ratio of waist circumference (WC) and/or body mass index (BMI) on cardiovascular risk factors. Methods Data on a cross-sectional study involving 41 087 adults (19 567 male, 21 520 female) from the 2002 China National Nutrition and Health Survey were examined. According to the obesity definition of the Chinese Working Group on Obesity for Children (WGOC) (BMI, 24 and 28 kg/m2; WC, male 85 cm, female 80 cm), the study population were divided into 9 groups. The prevalence and odds ratio (OR) of cardiovascular disease (CVD) risk factors were compared among these 9 groups. Variation and standard β were indexes being used to compare the likelihood of BMI and/or WC on CVD risk factors. Results Within each of the BMI categories, with few exceptions, indices levels on CVD risk factors were significantly increased (decreased for HDL-C levels) with the increase of WC, and vice versa. After adjusting the effects of age, sex, income, education, sedentary activity and dietary factors, the ORs of hypertension in adults with higher WC within each of the BMI categories were higher than adults with lower WC, and the ORs of hypertension in adults with higher BMI within each of the WC categories were higher than adults with lower BMI. Similar trends were found for high fast plasma glucose (FPG) and dyslipidemia. The variation in CVD risk factors explained only by WC and BMI were quite similar,but slightly larger when combined WC with BMI. Standard β was higher on BMI when predicting systolic BP and was higher on WC when predicting TG, TC and HDL-C. Conclusion BMI and WC were independently associated with the risk factors on CVD.To combine the BMI and WC, the results could accurately evaluate the risk of CVD, thus to provide substantive evidence that the WGOC cutoff points for the WC might help in identifying those population under increased risk.

Background: As the coronavirus disease 2019 (COVID-19) pandemic spreads globally, hospitals are rushing to adapt their facilities, which were not designed to deal with infections adequately. Here, we present the management of a suspected COVID-19 patient. Case: A 66-year-old man with a recent travel history, infective symptoms, and chest X-ray was presented to our hospital. Considering his septic condition, we decided to perform an emergency surgery. The patient was given supplemental oxygen through a face mask and transported to an operating theatre on a plastic-covered trolley. An experienced anesthetist performed rapid sequence intubation using a video laryngoscope. Due to the initial presentation of respiratory distress, the patient remained intubated after surgery to avoid re-intubation. Precautions against droplet, contact, and airborne infection were instituted. Conclusions Our objective was to facilitate surgical management of patients with known or suspected COVID-19 while minimizing the risk of nosocomial transmission to healthcare workers and other patients.

OBJECTIVETo investigate the effect of fluvastatin on blood levels of c-reactive protein (CRP), tumor necrosis factor alpha (TNFalpha) and cardiac troponin I (cTnI) in patients with unstable angina undergoing percutaneous coronary intervention (PCI).

METHODSSixty patients who underwent PCI from July 2002 to April 2004 in our hospital were randomized into two groups: control group; fluvastatin group (40 mg/d). Serum levels of CRP, TNFalpha and cTnI were measured before and after two weeks treatment (in the early morning of the procedure) and at 24 hours after the procedure.

RESULTSThe serum levels of CRP, TNFalpha and cTnI in fluvastatin group were distinctly lower than those in control group before (P < 0.01) and after the procedure (P < 0.01), respectively.

CONCLUSIONThe result suggested that PCI could lead to a detectable increase in serum levels of CRP, TNFalpha and cTnI in patients with coronary heart disease; Fluvastatin could significantly decrease the serum levels of CRP, TNFalpha and cTnI in patients with coronary heart disease; Fluvastatin could also decrease the serum levels of CRP, TNFalpha and cTnI in patients with PCI.
