Objective To investigate effects of Danhong on the serum levels of CD137, high-sensitivity C-reactive protein (hs-CRP) and homocysteine (Hcy) in patients with non-ST elevation acute myocardial infarction complicating metabolic syndrome. Methods A total of 126 patients with non-ST elevation acute myocardial infarction complicating metabolic syndrome were enrolled and randomly divided into a conventional treatment group and a Danhong treatment group using a random-digit table, with 63 patients in each group. All patients underwent angiography or percutaneous coronary intervention. The patients in the Danhong treatment group treated with intravenous Danhong 20 ml on the basis of conventional treatment for 1 week. The serum levels of CD137, hs-CRP and Hcy were measured at hospital admission and 10 days after treatment. The severity of coronary artery disease was assessed by the Gensini-score. Results The levels of CD137, hs-CRP and Hcy in both groups after treatment were significantly lower than before treatment (conventional treatment group: t 12.393, 17.408 and 9.458; Danhong treatment group: t 16.110, 17.573 and 13.481; all P<0.01), and the Danhong treatment group were significantly decreased than the conventional treatment group (t 2.815, 3.224 and 3.157, all P<0.01). The serum levels of CD137 and hs-CRP before treatment were significantly correlated with Gensini scores in 126 patients (r 0.720 and 0.562,all P<0.01). Conclusions The serum levels of CD137 and hs-CRP are significantly correlated with the severity of coronary artery disease, intravenous Danhong may has protective effect for coronary artery disease via decreasing CD137 and hs-CRP.

OBJECTIVETo evaluate the clinical value of MDCT and MRI in the diagnosis and treatment of complex fractures of tibial plateau.

METHODSFrom March 2004 to January 2009,71 patients with complex fractures of tibial plateau estimated Schatzker III, V and VI were included in the study. Their X-ray films, MDCT, MRI were analyzed and compared. Twenty-four patients (14 males and 10 females with a mean age of 33.6 years) were treated with double incision and single plate. Average follow-up period was 31.4 months. Twenty-one patients (12 males and 9 females with a mean age of 33.2 years) were treated with double incision and bilateral plates. Average follow-up period was 28.4 months. Twenty-six patients (17 males and 9 females with a mean age of 35.3 years) were treated with bilateral plates via genicular anterior midline incision. Average follow-up period was 28.4 months. The index such as diagnosis correction for fracture location, fracture comminuted degree,fracture displacement degree,bone defect degree,and positive ration for number of collapsed joint surface,injuries of cruciate ligament, collateral ligament and menisci of knee joint.

RESULTSThe satisfaction score of X-ray flims, MDCT and MRI were (1.04 +/- 0.20), (1.82 +/- 0.38) and (1.12 +/- 0.33) separately for fracture positions; (0.81 +/- 0.51), (1.92 +/- 0.26) and (0.83 +/- 0.60) separately for fractures comminuted degree; (1.23 +/- 0.48), (1.92 +/- 0.26) and (0.46 +/- 0.58) separately for fracture displacement degree; (0.36 +/- 0.51), (1.55 +/- 0.79) and (0.26 +/- 0.53) separately for bone defect; the number of patients having collapse of tibial articular surface were 6,61 and 12 separately; the number of patients having cruciate ligaments were 3,10 and 17 separately; the number of patients having menisci injuries were 0,0 and 6 separately;the number of patients having collateral ligament injuries were 1, 1 and 8 separately. MDCT was the most sensitive method in the diagnosis of tibial articular surface collapse,avulsion tibial fracture at the point of cruciate ligament,fracture comminuted degree and fracture displacement degree (P < 0.01). MRI was the most sensitive method in the diagnosis of injuries of cruciate ligament, collateral ligament, menisci, the cartilage peeling of articular surface (P < 0.01).

CONCLUSIONMDCT and MRI further detail the Schatzker classification based on X-ray films, which also conduce to make precise diagnosis and reasonable treatments. MDCT and MRI are more sensitive for the diagnosis of insidious damages around knee.

There is continuous debate regarding the effectiveness of thymectomy in the treatment of non-thymomatous myasthenia gravis (MG). This systematic review was undertaken to determine whether thymectomy was effective in non-thymomatous MG. We retrieved articles published between January 1980 and September 2013. Sixteen cohort studies were included. Given the considerable heterogeneity, we used a descriptive method instead of statistical synthesis. The median relative rates (RRs) and their interquartile ranges were used to estimate the magnitude of benefit. Compared to conservatively treated MG patients, thymectomized patients had higher survival, clinical remission, pharmacologic remission and improvement rates, and RRs were 1.07 (1.01-1.17), 1.83 (0.82-2.99), 1.55 (1.22-1.95) and 1 (1.00-1.09), respectively. Subgroup analyses showed that patients with moderate to severe generalized MG benefited more from thymectomy, with RRs of survival and pharmacologic remission increasing to 1.35 (1.24-1.49) and 2.68 (1.73-4.17), respectively. These results suggested that thymectomy might be an effective procedure in non-thymomatous MG patients. The patients with moderate to severe generalized MG might benefit more. Taking into account the poor methodological quality of present studies, more well-designed prospective randomized controlled trials (RCTs) are still required to reach unequivocal conclusion.

BACKGROUNDStroke and traumatic injury to the nerve system may trigger axonal destruction and the formation of scar tissue, cystic cavitations and physical gaps. Olfactory ensheathing cells (OECs) can secrete neurotrophic factors to promote neurite growth and thus act as a prime candidate for autologous transplantation. Biological scaffolds can provide a robust delivery vehicle to injured nerve tissue for neural cell transplantation strategies, owing to the porous three-dimensional structures (3D). So transplantation of the purposeful cells seeded scaffolds may be a promising method for nerve tissue repair. This study aimed to evaluate the compatibility of a novel collagen-heparan sulfate biological scaffold with olfactory ensheathing cells in vitro.

METHODSCollagen-heparan sulfate (CHS) biological scaffolds were made, and then the scaffolds and OECs were co-cultured in vitro. The viability of OECs was tested by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium (MTT) assay at days 1, 3, 5 and 7. Statistical analysis was evaluated by student's t test. Significance was accepted at P < 0.05. OECs were labeled with carboxyfluorescein diacetate succinimidyl ester (CFSE), and the CFSE-labeled OECs were seeded into CHS scaffolds. The attachment and growth of OECs in CHS scaffolds were observed and traced directly by fluorescent microscopy and environmental scanning electron microscope (ESEM).

RESULTSCHS biological scaffolds had steady porous 3D structures and no cytotoxicity to OECs (F = 0.14, P = 0.9330). CHS biological scaffolds were good bridging materials for OECs attachment and proliferation, and they promoted the axonal growth.

CONCLUSIONThe compatibility of CHS biological scaffolds with OECs is pretty good and CHS biological scaffold is a promising cell carrier for the implantation of OECs in nerve tissue bioengineering.

Objective To investigate the bacterial resistance in nationwide and understand the distribution of bacterial and resistance trend.MethodsThe 6507 clinical isolates were collected from 19 hospitals in 17 cities.The susceptibility tests were performed using agar dilution method recommended by Clinical and Laboratory Standards Institute (CLSI) in central laboratory.The values of MIC50,MIC90 and MICrange were calculated by SPSS 17.0 and the susceptibilities of isolates to antimicrobial agents were determined by using CLSI (2010) guideline.Of all 6507 isolates,4691 strains were collected from target wards and 1816 were isolated from others wards.ResultsAmong 4691 strains,1156 were Gram-positive (24.6％ ) and 3535 were Gram-negative (75.4％).Based on the minimum inhibitory concentration results,the prevalence of methicillin resistant Stapylococcus aureus and methicillin resistant Stapylococcus epidermidis are 51.6％ ( 325/630 ) and 87.0％ ( 228/262 ) respectively.Staphylococci showing intermediate or full resistance to vancomycin were not observed. Coagulase negative Staphylococci showed 2.5％ (16/642)intermediate rate and 1.6％ ( 10/642 ) full resistance rate to teicoplanin,and showed 0.5％ ( 3/642 )resistance rate to linezolid.Antibiotic resistance rate of Enterococcus faecalis to ampicillin was 17.1％(19/111),while the resistance rate of Enterococcus faecium to ampicillin reached up to 85.0％(164/193).Three Enterococcus faecium were resistant to glycopeptides.The prevalence of penicillin resistance Streptococcus pneumoniae and penicillin intermediate Streptococcus pneumoniae were 41.2％ ( 145/352) and 37.2％ (131/352) respectively based on oral penicillin criterion,while the prevalence were 0.0％ (0/352) and 6.0％(21/352) based on vein to non-meningitis criterion.A vast majority of Enterobacteriaceae maintained high susceptibility to carbapenems,with resistance rate less than 2.0％.In addition,tigecycline,moxalactam,fosfomycin and amikacin displayed desirable antibacterial activity against Enterbacteriaceae,and resistance rates to these drugs were all less than 10.0％.For non-fermenting Gramnegative isolates,resistance rate of Pseudomonas aeruginosa and Acinetobacter baumannii to imipenem were 23.1％ ( 139/601 ) and 53.5％ (419/784) respectively.Resistance rate of Acinetobacter baumannii was much higher than that during the period 2007 - 2008.Colistin,tigecycline,minocycline and fosfomycin demonstrated good antibacterial activity against Acinetobacter baumannii in vitro.Conclusions Compared with MOHNARIN 2007 -2008year surveillance results, significant increase in resistance rate of Acinetobacter baumannii was demonstrated.Resistant strains to linezolid and tigecycline were found.Bacterial resistance has been a widespread problem in our country,which requires much more attention.

Objective:To explore the relationship between soft markers found in the first trimester (11-13 + 6 gestational weeks) ultrasound screening and fetal adverse pregnancy outcomes. Methods:Single pregnancy fetuses were selected from the Multicenter Clinical Study of First Trimester Screening in China during August 2017 to August 2020. The types and detection rate of soft markers during the first trimester were compared. The correlation between positive soft markers and adverse pregnancy outcomes was analyzed by binary Logistics regression.Results:A total of 16 625 fetuses with complete follow-up outcomes were included in the group. Six hundred and seven ultrasonic soft markers were detected in 556 fetuses with positive soft markers during the first trimester, and the first four most frequently occurred were increased nuchal translucency (NT) (2.08%, 345/16 625), echogenic intracardiac focus (EIF) (0.94%, 156/16 625), hypoplasia of fetal nasal bone (0.20%, 34/16 625), single umbilical artery (SUA) (0.19%, 31/16 625). Among 556 fetuses, the incidence of adverse pregnancy outcome in fetuses with two or more positive soft markers was 32.50% (13/40), which was significantly higher than fetuses with single positive soft marker (11.05%, 57/516), and the difference was statistically significant (χ 2=5.055, P<0.001). The incidence of adverse pregnancy outcome in positive soft markers fetus associated with structural abnormalities was 80.77% (21/26), which was significantly higher than fetuses with isolated positive soft marker (12.08%, 64/530), and the difference was statistically significant (χ 2=90.310, P<0.001). Binary logistic regression analysis showed choroid plexus cyst (CPC), SUA, echogenic bowel (EB), absent/reversed a-wave of ductus venosus, hypoplasia of fetal nasal bone, increased NT, and EIF were closely related to the adverse pregnancy outcomes (all P<0.05). However, there were no significant correlations between tricuspid regurgitation (TR), pyelectasis (PYE) and fetal adverse pregnancy outcomes (all P>0.05). Conclusions:The ultrasonic soft markers during the first trimester are of great significance in predicting fetal adverse pregnancy outcomes. For multiple positive soft markers or positive soft markers combined with structural abnormalities, more attention should be paid to them and comprehensive evaluation is required to be carried out.

Objective:To explore the clinical value of prenatal ultrasound in diagnosis of fetal cleft lip and palate during first-trimester (11-13 + 6 gestational weeks). Methods:Ultrasonographic images were retrospectively selected from those fetuses who underwent first trimester scanning during July 2017 to June 2020 in the Affiliated Suzhou Hospital of Nanjing Medical University. Fetal facial mid-sagittal section and the retronasal triangle (RNT) section were combined together to evaluate whether the fetuses had cleft lip and palate (CLP) or not. All fetuses were followed up to birth or induced abortion.Results:A total of 5 520 fetuses were enrolled, with crown-rump length (CRL) between 45-84 mm. Seven cases of different types of CLP were detected by the 2 combined sections, including 4 cases with unilateral CLP, 1 case with median CLP, and 2 cases with bilateral CLP, which were confirmed by follow-up. In addition, 2 cases of isolated cleft lip (CL) were missed.Conclusions:Combination of fetal facial mid-sagittal section and RNT section is useful for the early diagnosis of fetal cleft lip and palate during first-trimester scanning.

Objective:To explore the diagnostic value of first-trimester and mid-trimester ultrasound in screening fetal pentalogy of Cantrell, and to analyze missed and misdiagnosed cases.Methods:The fetal ultrasound image characteristics of pentalogy of Cantrell diagnosed in the Affiliated Suzhou Hospital of Nanjing Medical University from March 2018 to November 2022 were retrospectively analyzed. The necessary sections and key features of ultrasound images for diagnosing the disease in first-trimester and mid-trimester were summarized. The diagnostic value of ultrasound screenings in first-trimester and mid-trimester was analyzed, and the progression of the disease during pregnancy was understood, the missed diagnosis rate and misdiagnosis rate were calculated, and the reasons for missing diagnosis were analyzed. All fetuses were followed up to birth or induction of labor.Pentalogy of Cantrell was divided into types Ⅰ, Ⅱ, and Ⅲ according to Toyama′s research.Results:Among the 120 190 fetuses, 13 cases of pentalogy of Cantrell were diagnosed by ultrasound in first-trimester and mid-trimester. Ultrasound predominantly showed the fetal heart being malpositioned outside the chest and the fetal abdominal contents bulging outside the abdominal cavity, and the sternumal echo was partially or completely missed in some cases. All 13 cases were confirmed by follow-up, including 1 case of type Ⅱ, and 12 cases of type Ⅲ. In addition, 1 missed case of type Ⅱ pentalogy of Cantrell was followed up after birth. The correct diagnostic rates of fetal pentalogy of Cantrell using standard ultrasound sections during the first-trimester and mid-trimester were 99.9% and 100%, the sensitivity were 88.9% and 100%, the specificity were both 100%, the positive predictive values were both 100%, and the negative predictive values were 99.9% and 100%, respectively.Conclusions:First-trimester and mid-trimester ultrasound screenings have high diagnostic accuracy for pentalogy of Cantrell, and early detection and early diagnosis are of great clinical significance for the guidance of pregnancy outcomes.
