OBJECTIVETo detect the expression of human similar expression to FGF gene(hSef) and fibroblast growth factor-2(FGF-2) and their correlation with epithelial ovarian tumor.

METHODSImmunohistochemical SP staining was used to detect the expression of hSef and FGF-2 proteins in 31 cases of epithelial ovarian carcinoma (EOC), 18 cases of benign epithelial tumor (BET), 10 cases of normal ovarian (NO) tissues collected from July 2007 to May 2008. The expression of hSef mRNA in 24 cases of EOC, BET and NO collected from July 2008 to May 2009 were analyzed by RT-PCR.

RESULTSThe results of immunohistochemical study showed that the expression of hSef in the EOC tissues were significantly lower than that in the NO and BET (P < 0.001). However, the expression of FGF-2 was higher (P = 0.002). The expression of hSef had a negative correlation with FGF-2 (r(s) = -0.324, P = 0.012). The RT-PCR results showed that there was a gradually declined trend of expression of hSef in NO, BET to EOC (P < 0.001), but the expression of FGF-2 in NO, BET to EOC was gradually increased (P < 0.001), with a significant negative correlation (NO: r(s) = -0.910, P < 0.001; BET: r(s) = -0.859, P < 0.001; EOC: r(s) = -0.888, P < 0.001).

CONCLUSIONSThe expression of hSef is decreased in epithelial ovarian carcinoma tissue, but the expression of FGF-2 is increased. It is likely that low hSef expression is related to the the carcinogenesis and development of epithelial ovarian carcinoma by suppressing the promoting effects of FGF-2 to cell proliferation.

OBJECTIVETo observe the effects of NBD-peptide pretreatment of the donor dendritic cells in immune tolerance induction in mouse allograft recipients and investigate the mechanisms.

METHODSBALB/c mouse DCs pretreated with NBD-peptide (NBD-Peptide-DC) were injected into the recipient C57BL/6 mice 7 days before transplantation. Cervical heterotopic heart transplantation model was established using the cuff technique and the cardiac allograft survival time was observed. Pathological analysis were performed to examine the graft injection and the responsiveness of the recipient spleen T cell to the donor alloantigen was determined by mixed lymphocyte reaction (MLR). The serum levels of cytokines were determined using ELISA.

RESULTSThe cardiac allograft survival time in the NBD-Peptide-DC-treated group (21.83-/+3.54 days) was significantly longer than that in the Day9-DC group (13.33-/+2.58 days) and PBS-treated group (6.66-/+1.21 days) (P<0.01), with also significantly lower pathological grade for graft rejection (P<0.01). The donor-derived NBD-Peptide-DCs induced alloantigen-specific T-cell hyporesponsiveness. In the NBD-Peptide-DC-treated group, the serum levels of IL-12 and IFN-gamma decreased significantly (P<0.01), but the levels of IL-4 and IL-10 increased significantly (P<0.01).

CONCLUSIONInjection of donor-derived NBD-Peptide-DCs can leads to donor-specific tolerance in the transplant recipients, and the induction of recipient T-cell hyporesponsiveness and polarization of Th2 response may play important roles in immune tolerance to cardiac allografts.

BACKGROUNDThe gender difference on long-term outcome in unselected patients after percutaneous coronary intervention (PCI) has not yet been fully investigated. This study aimed to evaluate the gender difference on five-year outcomes following EXCEL biodegradable polymer-coated sirolimus-eluting stenting in patients with coronary disease.

METHODSA total of 2077 "all comers", consisting of 1528 (73.6%) men and 549 (26.4%) women, who were exclusively treated with EXCEL coronary stents were enrolled in the prospective CREATE study at 59 centers from four countries. After propensity score matching, the baseline characteristics of the two groups were well matched. Recommended antiplatelet regimen was clopidogrel and aspirin for six months followed by chronic aspirin therapy. The primary outcome that was the rate of major adverse cardiac events (MACE), defined as a composite of cardiac mortality, non-fatal myocardial infarction (MI) and target lesion revascularization (TLR), and stent thrombosis (ST) at five years were compared between the two gender groups.

RESULTSIn the two groups, women had higher proportions of clinical risk factors, such as being elderly, diabetes mellitus, hypertension and hyperlipidemia, compared to men. Besides, the mean target vessel number per patient was higher and the mean reference vessel diameter smaller for women. Men had higher risks of cardiac death (3.7% vs. 1.6%, P = 0.021) and MACE (8.4% vs. 4.7%, P = 0.004) at five years compared with women. However, the cumulative hazards of non-fatal MI and TLR were similar between men and women. The incidence of Academic Research Consortium (ARC) definite or probable stent thrombosis was similar between the two groups (1.3% vs. 1.0%, P = 0.639). Prolonged clopidogrel therapy (>6 months) did not reduce the cumulative hazards of ST from six months to five years in both men (χ(2) = 0.098, log rank P = 0.754) and women (χ(2) = 2.043, log rank P = 0.153) patients.

CONCLUSIONSWomen had a lower MACE and cardiac death rate than men after biodegradable polymer-coated sirolimus-eluting stenting in long term follow-up. Effects of prolonged dual antiplatelet therapy (DAPT) in preventing stent thrombosis was similar with six-month DAPT after EXCEL stent implantation in both men and women groups.

OBJECTIVETo evaluate the usefulness of multi-slice spiral CT (MSCT) in the post-operative assessment of cochlear implanted electrode.

METHODSTwenty-three cochlear implant recipients were enrolled in this study. All patients were examined with a SOMATOM Sensation 16-slice CT scanner (Siemens) using the following parameters: 120 kV, 100 mAs, 0. 75 mm collimation, 1 mm reconstruction slice thickness and increment, a pitch factor of 1, and a FOV of 100 mm. The axial images of interested ears were reconstructed with 0.1 mm increment and a FOV of 50 mm, and then volume rendering technique (VRT) reconstruction were done on the work station.

RESULTSThe electrode arrays were detected on axial CT images. Both inner ear and electrode array could be displayed on one image simultaneously. VRT provided an intuitionistic view of the relationship between electrode array and cochlea VRT showed the number of the electrode array in 20 patients implanted with Combi 40 + standard electrode array and demonstrated the shape, position, and insertion depth. The electrode array number determined by VRT was in accordance with the surgical findings in 18 patients, and was underestimated in two patients. In 3 patients with Combi 40 + compressed electrode array, only 4 to 5 electrodes arrays were clearly identified and others were not observed.

CONCLUSIONMSCT with VRT can provide useful three-dimensional information of the electrode array and indicate the exact relationship between electrode array and cochlea.

Conclusions There was a significant correlation between lesions of dorsal artery of foot and type 2 diabetes patient's condition. CDFI is an effective method in evaluating patient's condition, degree and prognosis of type 2 diabetes, and has an important clinical value in early diagnosis, prognosis and treatment.Simple arteriosclerosis showed focal lesions in bifurcation of the blood vessel while dorsal artery of foot showed relatively mild lesions .

BACKGROUND:The outcome of cardiopulmonary resuscitation (CPR) may depend on a variety of factors related to patient status or resuscitation management. To evaluate the factors influencing the outcome of CPR after cardiac arrest (CA) will be conducive to improve the effectiveness of resuscitation. Therefore, a study was designed to assess these factors in the emergency department (ED) of a city hospital.METHODS:A CPR registry conforming to the Utstein-style template was conducted in the ED of the First Affiliated Hospital of Wenzhou Medical College from January 2005 to December 2011. The outcomes of CPR were compared in various factors groups. The primary outcomes were rated to return of spontaneous circulation (ROSC), 24-hour survival, survival to discharge and discharge with favorable neurological outcomes. Univariate analysis and multivariable logistic regression analysis were performed to evaluate factors associated with survival.RESULTS:A total of 725 patients were analyzed in the study. Of these patients, 187 (25.8％) had ROSC, 100 (13.8％) survived for 24 hours, 48 (6.6％) survived to discharge, and 23 (3.2％) survived to discharge with favorable neurologic outcomes. A logistic regression analysis demonstrated that the independent predictors of ROSC included traumatic etiology, first monitored rhythms, CPR duration, and total adrenaline dose. The independent predictors of 24-hour survival included traumatic etiology, cardiac etiology, first monitored rhythm and CPR duration. Previous status, cardiac etiology, first monitored rhythms and CPR duration were included in independent predictors of survival to discharge and neurologically favorable survival to discharge.CONCLUSIONS:Shockable rhythms, CPR duration ≤15 minutes and total adrenaline dose ≤5 mg were favorable predictors of ROSC, whereas traumatic etiology was unfavorable. Cardiac etiology, shockable rhythms and CPR duration ≤15 minutes were favorable predictors of 24-hour survival, whereas traumatic etiology was unfavorable. Cardiac etiology, shockable rhythms, CPR duration ≤15 minutes were favorable predictors of survival to discharge and neurologically favorable survival to discharge, but previous terminal illness or multiple organ failure (MOF) was unfavorable.

Objective To investigate the clinical features of children with early-onset benign occipital epilepsy (EBOS) and children with late-onset benign occipital epilepsy (LOS) and their EEG changes,treatments and prognoses.Methods Sixty children with benign occipital epilepsy,admitted to our hospital from June 2007 to June 2012,were chosen in our study; their clinical data were retrospectively analyzed.According to the recommendations of the 2001 International League against Epilepsy (ILAE),these patients were divided into EBOS group (n=28) and LOS group (n=32); the clinical manifestations,electroencephalogram (EEG) characteristics,medication effectiveness in the two groups of children were compared.Results No significant difference on gender distribution,febrile convulsion histories and family history of epilepsy was noted between the two groups (P＞0.05); however,average ages of onset in the EBOS group were significantly younger than those in the LOS group (P＜ 0.05),and the onset time,seizure frequency,attack mode,seizures associated symptoms and seizure EEG waveforms in the EBOS group were obviously different as compared with those in the LOS group.Single-drug AED treatment could have control effect in 23 of children in the EBOS group and 12 of children in the LOS group; statistical difference was noted between the two groups (P＜0.05).Conclusion The onset time,seizure frequency,attack mode and seizures associated symptoms are obvious different between children with EBOS and LOS,and combined with seizure EEG waveforms,these differences can be used to identify the two.

Objective To analyze the distribution and antimicrobial resistance profile of clinical bacterial strains isolated from blood culture in China.Methods Clinical bacterial strains isolated from blood culture from participating hospitals of Blood Bacterial Resistance Investigation Collaborative System (BRICS) during January 2014 to December 2015 were collected.Antibiotic susceptibility tests were conducted with agar dilution or broth dilution methods as recommended by US Clinical and Laboratory Standards Institute(CLSI)2018.The data were analyzed with Whonet 5.6 software.Results During the study period,4 801 clinical bacterial isolates were collected from 26 hospitals,of which 1 798 (37.5％) were Gram-positive bacteria and 3 003 (62.5％) were gram-negative bacteria.The top 10 isolates were Escherichia coli (33.8％),coagulase-negative Staphylococcus (19.0％),Klebsiella pneumoniae (11.9％),Staphylococcus aureus (10.1％),Acinetobacter baumannii (4.0％),Pseudomonas aeruginosa (3.8％),Streptococcus (3.0％),Enterobacter sulcus (2.9％),Enterococcus faecium (2.8％) and Enterococcus faecalis (1.8％).Methicillin-resistant Staphylococcus aureus (MRSA) and methicillinresistant coagulase-negative Staphylococcus (MRCNS) accounted for 33.9％ (165/487) and 56.9％ (520/913) of Staphylococcus aureus and coagulase-negative Staphylococcus respectively.No vancomycinresistant Staphylococcus was detected.The resistance rate of Enterococcus faecium to vancomycin was 0.7％ (1/135),and no vancomycin-resistant Enterococcus faecaliss was detected.The positive rates of extendedspectrum β-1actamases(ESBLs)-producing Escherichia coli,Klebsiella pneumoniae and Proteus were 56.9％ (923/1 621),30.1％ (172/572) and 29.2％ (7/24),respectively.The positive rates of carbapenemresistant Escherichia coli,Klebsiella pneumoniae,Enterobacter,Salmonella and Citrobacter were 1.2％ (20/1 621),7.2％ (41/572),4.3％ (6/141),1.5％ (1/67) and 2.9％ (1/34),respectively.The resistance rates of Acinetobacter baumannii to polymyxin and tegacycline were 2.6％ (5/190) and 8.9％ (17/190)respectively,and that of Pseudomonas aeruginosa to polymyxin and fosfomycin were 1.1％ (2/183)and 0.6％ (1/183),respectively.Conclusions The surveillance results from 2014 to 2015 show that the main pathogens of blood stream infection in China are Gram-negative bacteria,while Escherichia coli is the most common pathogen,the detection rate of MRSA is lower than other surveillance data in the same period in China;carbapenem-resistant Klebsiella pneumoniae and Escherichia coli are at a low level as shown in this surveillance.

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

Background: Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. Methods: Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. Results: The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. Conclusion The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.
