BACKGROUNDDiffusion weighted imaging with background suppression (DWIBS) is potentially useful in detecting metastatic lymph nodes. This study aimed to evaluate the efficacy of DWIBS at 3T magnetic resonance (MR) for diagnosing metastatic lymph nodes in cervical cancer.

METHODSThis retrospective study included 25 patients with cervical cancer who underwent MR examination and were treated by hysterectomy and lymphadenectomy. The metastatic and non-metastatic lymph nodes were histologically proven by operation. Apparent diffusion coefficient (ADC) values, long-axis diameters, short-axis diameters, ratio of short- to long-axis diameters of all the identifiable lymph nodes were measured and compared.

RESULTSTwenty-five primary tumor lesions, 17 metastatic lymph nodes and 140 non-metastatic lymph nodes were pathologically confirmed in 25 cases with cervical cancer. The difference of ADC values between primary tumor lesions, metastatic and non-metastatic lymph nodes were statistically significant (F = 7.93, P = 0.001). There was no statistically significant difference between primary tumor lesions of cervical cancer and metastatic lymph nodes (t = -0.75, P = 0.456), and the difference between primary tumor lesions and non-metastatic lymph nodes was statistically significant (t = 4.68, P < 0.001). The ADC values, long-axis diameters, short-axis diameters, ratio of short- to long-axis diameters of metastatic and non-metastatic lymph nodes were (0.86 ± 0.36) × 10(-3) mm(2)/s vs. (1.12 ± 0.34) × 10(-3) mm(2)/s, (1.51 ± 0.41) cm vs. (1.19 ± 0.36) cm, (1.16 ± 0.35) cm vs. (0.77 ± 0.22) cm, 0.78 ± 0.17 vs. 0.68 ± 0.19 respectively, and statistically significant difference existed between two groups.

CONCLUSIONSDWIBS at 3T MR has the distinct advantages in detecting pelvic lymph nodes of cervical cancer. Quantitative measurement of ADC values could reflect the degree of restriction of diffusion of metastatic and non-metastatic lymph nodes. The combination of size and ADC value would be useful in the accurate diagnosis of metastatic lymph nodes.

OBJECTIVEThe aim of this study was to elucidate the role of EGFR expression and HPV infection and their relationship in the genesis and progression of cervical carcinoma.

METHODSThis analysis included 60 cases of cervical carcinoma, 40 cases of CIN and 30 cases of control group. Patients of cervical carcinoma group were all subjected to radical hysterectomy with bilateral pelvic lymphadenectomy in Tumour Hospital, Zhongshan University from 1997 to 2001. The FIGO stage was I a - II b. EGFR protein was stained by S-P immunohistochemistry, and HPV16/18 DNA was detected by PCR.

RESULTSThe moderate/ strong expression of EGFR was observed in 0, 42.5%, 76.7% of normal cervical epithelium, CIN and cervical tumor tissue, respectively, with a significant difference among them (P < 0.05). The infection of HPV16/18 was observed in 6.7%, 67.5%, 58.3% of normal cervical tissue, CIN and cervical tumors, respectively. The infection rate of CIN or cervical carcinoma was significantly higher than that in normal cervicaltissue (P = 0.000), but no statistically significant difference was observed between cervical carcinoma and CIN. The moderate/strong expression of EGFR demonstrated an association with the cervical invasion depth. The EGFR expression increased significantly as the invasion depth progressed from less than or equal to a half cervical stroma to deeper than that (89.2% vs. 56.5%, P = 0.004). The infection of HPV16/18 demonstrated a correlation with the cervical canal invasion. The infection increased significantly in the cases with cervical invasion than that in the cases without invasion (88.2% vs. 46.5%, P = 0.003). But no significant correlation was observed between EGFR and HPV. Neither EGFR nor HPV had a significant association with carcinoma prognosis.

CONCLUSIONEGFR and HPV demonstrate a significant correlation with genesis and progression of cervical carcinoma. In our study, neither EGFR nor HPV demonstrates a significant association with tumor prognosis, and no significant correlation is observed between EGFR and HPV.

OBJECTIVE: To analyze the clinical characteristics and treatment effects of children with acute megakaryoblastic leukemia without down syndrome (non-DS-AMKL). METHODS: The clinical data of 19 children with non-DS-AMKL treated in the Pediatric Hematology Ward in Sun Yat-sen Memorial Hospital of Sun Yat-sen University from May 2008 to April 2018 were analyzed retrospectively. The clinical characteristics, laboratory test and treatment methods of the children were concluded. All patients were followed up to evaluate the effect of treatment. RESULTS: The 19 cases of children included nine male and ten female, the median age of onset was 2 years old. The clinical manifestations showed nonspecific. The median white blood cell of peripheral blood was 15.88×10 CONCLUSION Non-DS-AMKL was rare in children and difficult to be diagnosed. Determination of MICM classification as early as possible was helpful for diagnosis, and genetic testing played an important role for diagnosis and prognosis evaluation. Early hematopoietic stem cell transplantation in patients with CR after chemotherapy might be an effective way to cure AMKL.

BACKGROUNDMetabolic syndrome (MS) is a risk factor for stroke and thromboembolism event. Left atrial or LA appendage (LA/LAA) thrombus is a surrogate of potential stroke. The relationship between MS and atrial thrombus remains unclear. In this study, we sought to investigate the effect of MS on risk stratification of LA/LAA thrombus formation in patients with nonvalvular atrial fibrillation (NVAF).

METHODSThis cross-sectional study enrolled 294 consecutive NVAF patients without prior anticoagulant and lipid-lowering therapies. LA/LAA thrombus was determined by transesophageal echocardiography. Risk assessment of LA/LAA thrombus was performed using the CHADS2 , CHA2DS2 -VASc, MS, CHADS2 -MS, and CHA2DS2 -VASc-MS scores. Logistic regression analyses were performed to determine which factors were significantly related to LA/LAA thrombus. Odds ratio (OR) including 95% confidence interval was also calculated. The predictive powers of different scores for the risk of LA/LAA thrombus were represented by C-statistics and compared by receiver operating characteristic (ROC) analysis.

RESULTSLA/LAA thrombi were identified in 56 patients (19.0%). Logistic analysis showed that MS was the strongest risk factor for LA/LAA thrombus in NVAF patients (OR = 14.698, P < 0.001). ROC curve analyses revealed that the C-statistics of CHADS2 -MS and CHA2DS2 -VASc-MS was significantly higher than those of CHADS2 and CHA2DS2 -VASc scores (CHADS2 -MS vs. CHADS2 , 0.807 vs. 0.726, P = 0.0019). Furthermore, MS was helpful for identifying individuals with a high risk of LA/LAA thrombus in the population with a low risk of stroke (CHADS2 or CHA2DS2 -VASc score = 0).

CONCLUSIONSMS is associated with LA/LAA thrombus risk in patients with NVAF. In addition to the CHADS2 and CHA2DS2 -VASc scores, the CHADS2 -MS and CHA2DS2 -VASc-MS scores provide additional information on stroke risk assessment.

OBJECTIVETo compare the therapeutic effect and side effect of the treatments on hyperthyroid exophthalmos with the combination of acupuncture and medication and with medication only.

METHODSFifty-two cases were randomly divided into an acupuncture and medication group (27 cases) and a medication group (25 cases). Acupuncture in combination of oral taking of Thiamazole and Euthyrox were adopted for the acupuncture and medication group. And acupoints such as Jingming (BL 1), Chengqi (ST 1) and Sizhukong (TE 23) etc. were selected. Western medication for oral taking was applied as the only treatment for the medication group. Objective eye syndrome marks, side effects and accidents were compared between two groups before and after treatment.

RESULTSThe improvement of the objective marks of eye syndrome in the acupuncture and medication group was better than that in the medication group (P < 0.01). There were 4 cases with hypoleucocytosis, 3 cases with rash and 3 cases with aggravated symptom of exophthalmos in the medication group during the treatment, while no case with side effects was observed in the acupuncture and medication group. However, 8 cases were found with hemorrhage and 8 with hematoma in the acupuncture and medication group.

CONCLUSIONTreatment with the combination of acupuncture and medication may not only enhance the therapeutic effect, but also reduce the side effects.
