Background and purpose:Axillary lymph node metastasis of breast cancer has an important significance in prognosis and treatment of breast cancer. This study was to investigate the correlation between axillary lymph node metastasis and ultrasonographic characteristics of axillary lymph node combined with immunohistochemistry in breast cancer patients.Methods:A total number of 366 breast cancer patients were selected in this study. Seven hundred and twenty-eight axillary lymph nodes were collected. With ultrasonography, the maximum cortex thickness, the ratio of the height to the length, the ratio of the cortex to the medulla and blood lfow of axillary lymph nodes were observed, in order to study the correlation between these indicators and axillary lymph node metastasis combined with the postoperative immunohistochemical results.Results:According to univariate analysis, axillary lymph node maximum cortex thickness, the ratio of the height to the length, characteristics of blood flow and the positive expression rate of p53 were related to axillary lymph node metastasis (P<0.05). Multivariate logistic regression analysis and receiver operating characteristic (ROC) curve showed that axillary lymph node maximum cortex thickness was the best indicator to determine axillary lymph node metastasis. The positive expression rate of p53 in patients with maximum cortex thickness >3 mm (42.78%) of axillary lymph node was signiifcantly higher than that in patients with maximum cortex thickness≤3 mm (25.82%) (P<0.01).Conclusion:Ultrasonographic characteristics of axillary lymph node and immunohistochemistry method are closely correlated with axillary lymph node metastasis in patients with breast cancer, which is important in diagnostic and treatment in clinic.

AIM: To observe the clinical effect of the tonifying kidney pills with mingmuwuzi treating evaporative dry eyes.METHODS: This study adopted the positive drug control,prospective study,random number remainder grouping method to 65 cases of outpatient patients diagnosed with evaporative dry eyes which were divided into the treatment group 32 cases (64 eyes) and the control group 33 cases (66 eyes).The treatment group took the decoction of kidney pills with mingmuwuzi,combined with sodium hyaluronate eye drops.The control group simply use sodium hyaluronate eye drops,both group were set to 4wk for a course of treatment.To observe the symptoms and signs of two groups before and after the treatment,the change of the evaluation index and curative effect were evaluated.RESULTS: The effectiveness of the treatment group was 87.5%,the control group was 78.8%,the difference was statistically significant (z=-3.149,P<0.05).CONCLUSION: The treatment of the kidney pills with mingmuwuzi combined with sodium hyaluronate eye drops to evaporative dry eyes is more effective than the simple use of sodium hyaluronate eye drops.

CD38 is a multifunctional enzyme expressed in a variety of mammalian tissues, its catalytic activity was involved in a wide range of physiological processes. Based on the reported inhibitor of human CD38 NADase, 33 purine derivatives were designed and synthesized. The biological activity assay showed that compounds 20 and 38 exhibited almost the same extent of inhibitory activities on human CD38 NADase as the lead compound H2. The results also revealed that small substituents at C-6 of purine ring gave no obvious effect on inhibitory activity, but phenylpropionyl moiety at N-2 could affect the binding mode of the compound with CD38. This study provides a reliable basis for future rational design of inhibitors for CD38.

OBJECTIVEThis study aims to evaluate the quality of life (QOL) of patients who underwent resection of oral cancer and reconstruction by free anierolateral thigh perforator flaps (ALTF).

METHODSA total of 32 patients with oral and maxillofacial malignancies who had undergone the resection of oral cancer and reconstruction by ALTF were retrospectively analyzed. At 12 months postoperatively, the QOL of these patients was assessed by using the 14-item oral health impact profile (OHIP-14) and the medical outcome study short form-36 (SF-36) questionnaires.

RESULTSA total of 32 questionnaires were collected. In SF-36, the highest scoring domains were bodily pain (78.58 ± 14.82), physical functioning (72.08 ± 27.86), and the role of physical (60.00 ± 42.63), whereas the lowest scoring domains were role-emotional (41.67 ± 39.62), followed by mental health (50.75 ± 13.07) and health transition (54.17 ± 21.75). In OHIP-14, the lowest scoring domains were social disability (34.50 ± 11.32) and handicap (36.04 ± 12.05), indicating the functional recovery was better; and the highest scoring domains were physical pain (73.50 ± 18.96) and psychological discomfort (60.17 ± 20.66), indicating the functional recovery was worse.

CONCLUSIONThe ALTF is an ideal selection for the reconstruction of oral defects after cancer resection. In using this flap, the basic social need of patients after surgery can be satisfied. Moreover, the appearance and the functions of chewing, deglutition, and speech can be restored in varying degrees. Thus, ALTF can improve the patients' QOL.

AIMTo investigate the enhancing effect on insulin absorption through GI. tract in mice by using the Ulex europaeus agglutinin I (UEA1) modified liposomes as the carrier.

METHODSUEA1 modified phosphatidylethanolamine (PE) was prepared by conjugating method of 1-ethyl-3-(3'-dimethylaminopropyl) carbodiimide (EDC), then the modified compound (PE-UEA1) was incorporated into the conventional liposomes of insulin to obtain UEA1 modified liposomes. The agglutination test was performed to examine the UEA1 biological activities after synthesis and modification. When liposomes were applied to healthy mice or diabetic mice at insulin dose of 350 u x kg(-1) orally, the hypoglycemic effect was investigated according to the blood glucose level determination.

RESULTSThe blood glucose levels of the healthy mice reduced by UEA1 modified liposomes were (84 +/- 15)% at 4 h, (78 +/- 11)% at 8 h and (90 +/- 12)% at 12 h after oral administration. The conventional liposomes and saline showed no effect. The blood glucose levels of the diabetic mice reduced by UEA1 modified liposomes were (73 +/- 7)% at 4 h, (74 +/- 9)% at 8 h, (86 +/- 9)% at 12 h after oral administration.

CONCLUSIONThe UEA1 modified liposomes promote the oral absorption of insulin due to the specific-site combination on M cell membrane.
