Objective: To investigate the antimicrobial resistance status and pulsed field gel electrophoresis (PFGE) patterns of Salmonella enteritidis (S.enteritidis) in Shanxi Province in order to provide references for the treatment of Salmonella infection and for tracing the source of outbreaks of foodborne diseases. Methods: Sixty-four S. enteritidis strains were collected by monitoring sites for foodborne diseases from April 2015 to March 2018. Biochemical identification system and serotyping analysis were used for bacterial identification. Drug susceptibility patterns were analyzed with micro-broth dilution method. PFGE was used for molecular typing. Results: The antimicrobial resistance rate of 64 S. enteritidis strains to nalidixic acid (95.31%) was the highest, followed by that to ampicillin (90.63%) and to ampicillin/sulbactam (81.25%). They had lower resistance rates to cefazolin, cefotaxime, tetracycline, ceftazidime, trimethoprim/sulfamethoxzole and ciprofloxacin (3.13%-23.44%) and were all sensitive to chloramphenicol, cefotaxime, azithromycin, imipenem and gentamicin. No statistically significant difference in drug resistance rates was found between the sporadic strains and the outbreak strains (P>0.05). All 64 S. enteritidis strains digested with XbaⅠwere divided into 33 molecular patterns by PFGE. The numbers of bacteria contained in each pattern ranged from 1 to 10 strains. The similarity among patterns was between 54.6% and 100%. Conclusion More attention should be paid to the drug resistance status of S. enteritidis in Shanxi Province. It is necessary to strengthen the standardized administration of antibiotics. The PFGE patterns of S. enteritidis reveal the presence of significant genetic polymorphism. PFGE is of great significance in analyzing the genetic relationship among S. enteritidis strains and in identifying and tracing the source of outbreaks of foodborne diseases.

Objective To evaluate the clinical efficacy of Yangxue-Pinggan decoction on intractable headache. Methods A total of 66 patients with intractable headache who met the inclusion criteria were randomly divided into two groups by random number table method, 33 in each group. The control group was given flunarizine hydrochloride capsule orally, while the treatment group was given professor Guan Youbo's Yangxue-Pinggan decoction. Both groups were treated for 4 weeks. The improvement rates of headache were observed. The headache attacks, the degree of headache, the duration of headache and the accompanying symptoms were scored, and the clinical efficacy was evaluated. Results The total effective rate was 97.0％ (32/33) in the treatment group and 63.6％ (21/33) in the control group, which there was significant difference between the two groups (χ2=11.591, P=0.001). After treatment, the scores of the headache attacks, the degree of headache, the duration of headache and the accompanying symptoms in the treatment group were significantly lower than those in the control group (t=17.689, 12.523, 26.907, 25.569, P<0.001). Conclusions The Yangxue-Pinggan decoction can obviously improve the clinical symptoms of intractable headache, relieve the pain degree and reduce the number of attacks, and its clinical efficacy is better than oral flunarizine hydrochloride capsule.

OBJECTIVETo investigate the value of serum beta-human chorionic gonadotropin (β-HCG) on days 9 (d9) and 11 (d11) after fresh embryo transfer (ET) and frozen-thawed embryo transfer (FET) in predicting the pregnancy outcomes.

METHODSA total of 227 fresh ET and FET cycles performed at the Center of Reproductive Medicine, Qingyuan People's Hospital between Dec, 2012 and Feb, 2014 were analyzed. The data of serum β-HCG levels on d9 and d11 after fresh ET and FET cycles and the pregnancy outcomes were reviewed, and the ROC curve was constructed to determine the optimal cut-off level of serum β-HCG level for predicting pregnancy outcomes.

RESULTSAccording to pregnancy outcomes, the cycles were divided into non-pregnancy group (group A), biochemical pregnancy group (group B), and clinical pregnancy group (group C). Significant differences were found between the mean serum β-HCG levels measured on d9 and d11 in all the 3 groups (P<0.01). The cycles in group C were further divided into 5 subgroups with single pregnancy (C1), twin pregnancy (C2), early abortion (C3), ectopic pregnancy (C4), or intrauterine pregnancy complicated with ectopic pregnancy group (C5), and all the 5 subgroups showed significant differences in β-HCG measurements between d9 and d11 (P<0.01). On d9 after ET and FET, the optimal cut-off level of serum β-HCG was 49.05 IU/L for predicting for clinical pregnancy, and was 105.15 IU/L for predicting twin pregnancy; the two corresponding cut-off levels of serum β-HCG on d11 was 51.2 IU/L and 241.75 IU/L, respectively.

CONCLUSIONThe absolute serum β-HCG level on d9 and d11 after fresh ET and FET allows an accurate diagnosis of pregnancy and helps in the prediction of the pregnancy outcomes.

Objective: To study the clinicopathological features, diagnosis, and differential diagnosis of atypical epithelioid hemangioendothelioma (EHE). Methods: Eight cases of atypical EHEs were collected from Jiangsu Province Hospital (the First Affiliated Hospital of Nanjing Medical University) between 2010 and 2018. EnVision method and fluorescence in situ hybridization (FISH) were used to detect immunophenotype, WWTR1-CAMTA1 and TFE3 gene rearrangement, respectively. Results: There were 4 males and 4 females, ranging from 42 to 59 years (median 47.5 years). The tumors located in soft tissue (3 cases), lung (3 cases), liver (1 case) and chest wall (1 case). One soft tissue EHE involved also adjacent fibula and pleural involvement was present in all three lung cases at the diagnosis. Regional lymph node metastases were present in two cases (one involving soft tissue tumor and one involving liver). Morphologically, the tumor cells were epithelioid with abundant eosinophilic cytoplasm, moderate to marked nuclear pleomorphism, irregular nuclear membrane, unevenly chromatin, and prominent nucleoli. The cells arranged in cords, small nests or solid pattern. The mitotic rate was 4.3 mitoses/2 mm² on average (ranging 2 to 9). Tumor necrosis was seen in every case. Among all 8 cases, blister cells were found upon careful observation. Myxohyaline stroma was present in 6 cases. Immunohistochemically, tumor cells expressed CD31 (8/8), CD34 (7/8), ERG (8/8), CKpan (2/7), and CAMTA1 (4/6). None of the tested cases stained for TFE3 (0/6). WWTR1-CAMTA1 fusion gene by FISH was found in all tested 6 cases and TFE3 gene rearrangement was not detected in any. Available clinical follow-up was obtained in 7 cases and the intervals range from 6 to 55 months (average 19.6 months). Six patients had metastasis and 3 patients died of disease. One patient was alive with no evidence of disease. Conclusions Atypical EHE is a more aggressive tumor than classic EHE, with histological features including high nuclear grade, increased mitotic activity, the presence of solid growth pattern and tumor necrosis. The differential diagnoses include epithelioid angiosarcoma, carcinoma and epithelioid sarcoma.
