Purpose To investigate the relationship between HPV infection and p53,p16,EGFR expression and prognosis in patients with salivary adenoid cystic carcinoma (ACC).Methods Totally 76 cases of adenoid cystic carcinoma specimens were selected,PCR-reverse dot blot hybridization was used to detect infection of HPV and SP immunohistochemical method was adopted to detect the expression of p53,p16,EGFR,Cdc2 in tumor tissues.Clinical data were collected and all the patients were followed up.The Kaplan-Meier method was used to estimate median overall survival and the Log-rank test to compare survival curves.Cox regression model was used for multivariate analyses.Results Infection rate of HPV in adenoid cystic carcinoma tissues was 0(0/76).The expression rate of p53,p16,EGFR,Cdc2 protein in adenoid cystic carcinoma tissues were 76.3％ (58/76),57.9％ (44/76),60.5％ (46/76) and 64.5％ (49/76)respectively.There was no correlation of the expression of p53,p16,EGFR and Cdc2 with gender,age,tumor location,TNM stage and histological type of patient.Kaplan-Meier survival analysis showed that EGFR-positive patients had shorter median overall survival rate (OS) than the negative ones (x2 =19.111,P ＜ 0.001).EGFR-positive patients had shorter median progression-free survival rate (PFS)than the negative ones (x2 =6.621,P ＜ O.01).Cdc2 positive patients had shorter median OS than the negative ones (x2 =3.870,P ＜ 0.05).Cdc2 positive patients had shorter median PFS than the negative ones (x2 =6.755,P ＜0.01).Cox regression analysis showed that expression of EGFR and Cdc2 was independent risk factors for the prognosis of patients with salivary gland ACC (relativerisk=13.417,13.075,P＜0.001).Conclusion There is no HPV infection detected in adenoid cystic carcinoma tissues.p53,p16,EGFR and Cdc2 are positively expressed in most salivary adenoid cystic carcinoma,p16 is unsuitable as a surrogate for HPV infection status of patient with ACC.Expression of EGFR and Cdc2 is independent risk factors in the prognosis of patients with salivary gland ACC.For the EGFR or Cdc2 positive patients should be followed up closely.

Objective To study the relationship between the number of outpatient complaints and the time or the outpatient amounts.Methods A retrospective analysis of 1289 cases of outpatients' medical complaints with basic records since 2009 in our hospital was carried out.The time regularity of the number of outpatient complaints,or the complaint rate was analyzed.And the correlation between the outpatient amounts and the number of outpatient complaints,or the complaint rate was also analyzed.Results In our hospital,the mean monthly number of outpatient complaints was (23.44±8.41)cases; the mean monthly outpatient account was (246 000±27 417)cases.The differences among monthly outpatient complaints,outpatient accounts and monthly complaints rate among every years were statistically significant.Within one year,the outpatient complaints numbers were lowest in February and January.And the outpatient complaints rate was low in November,January,February and December.There were statistically significant correlation between the monthly outpatient complaints and monthly outpatient accounts,and between the monthly outpatient complaints rate and monthly outpatient accounts.Conclusions There was time regularity in the outpatient complaints rates in one year.And there was certain correlation between the outpatient complaints rate and the outpatients' accounts.

Objective To evaluate the effcacy of electron-beam chest-wall irradiation in patients with breast cancer after mastectomy.Methods From June 1999 to December 2007,280 women with localized breast cancer received postmastectomy radiotherapy using electron beam to chest wall.The effcacy and toxicity of these 280 women was compared with 118 women treated during the same period using tangential field with photon beam.Results The follow-up rate was 93.2%.140 patients had a minimum followed up time of 5 years and 12 patients had a minimum follow up time of 10 years.The 5-year and 10-year chest wall recurrence rates were 6.8%and 5.0%.14.8%and 10.1%for patients irradiated with electron and photon(X2=1.12,P=0.290).The corresponding 5-year and 10-year disease-free survival rates were 60.6%and 65.5%,47.6%and 57.3%(X2=0.97,P=0.325).The 5-year and 10-year overall survival rates were 77.5%and 79.6%,48.4%and 53.3%(X2=0.37,P=0.545).Grade Ⅱ or more acute skin toxicity occurred in 10.4%and 16.9%of patients irradiated with electron and photon(X2=3.34.P=0.090).Pulmonary fibrosis developed in 28.8%and 22.1% of patients irradiated with electron and photon(X2=1.27,P=0.300).Conclusion Electron-beam chest-wall irradiation is as effective as photon-beam irradiation in breast cancer after mustectomy.

Objective To analyze the prognosis of T1-T2 stage breast cancer with 1 -3 positive axillary nodes after mastectomy, and to explore a subgroup of patients who could benefit from adjuvant radiotherapy. Methods In the retrospective study of 412 eligible patients, survival analysis was performed using the Kaplan-Meier method. Univariate and multivariate analyses were performed using the Log-rank method and Cox regression analysis, respectively. Results The follow-up rate was 98. 7%. 215 and 41patients were followed up for 5 and 10 years,respectively. The 5-and 10-year overall survival (OS) rate was 90. 0% and 81.3%, respectively. The 5-and 10-year locoregional recurrence (LRR) rate was 10. 7% and 18. 6%, respectively. In univariate analysis, T2 statging, more than one positive node, hormone receptornegative ( ER&PR-negative), ratio of positive lymph nodes (LNR) ＞ 25%, Her-2 positive, no hormonal therapy were associated with a significantly higher rate of LRR. T2 staging, more than one positive node,hormone receptor-negative were the risk factors for LRR with statistical significance in the multivariate analysis. Basing on these 3 risk factors, the high-risk group (with 2 -3 factors) had a 10-year LRR rate of 36. 9% compared with 3.9% in the low-risk group ( with 0 - 1 factors;x2 =20. 64,P =0. 000). The 5-year and 10-year distant metastasis (DM) rate was 12.9% and 24. 5%, respectively. LRR, and LNR ＞25%were statistically significant predictors of DM in the multivariate analysis. The 5-year DM rate for patients with LRR was 36. 6% compared with 9. 7% without LRR (x2 = 16. 34,P =0. 000). The 5-year OS rate for patients with LRR was 69. 9% compared with 92. 9% without LRR ( x2 = 20. 79, P = 0. 000). LRR was associated with a higher risk of distant metastasis and worse survival. Conclusions LRR after mastectomy has a significant impact on the outcome of patients with T1 -T2 breast cancer and 1 - 3 positive axillary nodes.Patients who have 2 -3 risk factors might benefit from radiotherapy.

AIM: To detect the effect of conjunction matrigel with mammary fad pat(MFP)implantation on the tumorigenesis, proliferation, apoptosis and metastasis of Her2 positive and negative breast cancer model. METHODS: The Her2 positive BT 474 and Her2 negative MDA-MB 231 breast cancer cells were injected into MFP of nude mice with or without matrigel to establish breast cancer model. The tumor volume was measured every 3 d. Followed up for 30 d after implantation, the nude mice were killed and the tumors and associated organs were dissected for pathological sectioning and staining with hematoxylin and eosin. The time of tumor formation and the tumorigenesis were determined after implantation. The tumor volume and metastasis rate were calculated and compared with each other. The proliferation and apoptosis of Her2 positive and negative tumors were also determined. RESULTS: Matrigel and MFP implantation technology shortened the time of tumorigenesis significantly(P<0.01). The tumorigenesis rate of BT 474 and MDA-MB 231 breast cancer cells did not show any different(P>0.05). The metastasis rate of MDA-MB 231 breast cancer cells were improved from 25.0% to 37.5%(P<0.05). CONCLUSION: Matrigel and MFP implantation can be combined to shorten the time of tumor formation by two kinds of breast cancer cells, and improve the metastasis of Her2 negative MDA-MB 231 cells. Using matrigel does not show any effect of proliferation and apoptosis on Her2 positive and negative breast cancer cells.

Objective: To explore the preventive effect and possible molecular mechanism of dietary supplementation of N-carbamylglutamate (NCG) in the implantation of carbon disulfide (CS₂) into embryo implantation disorders. Methods: embryo implantation disorder model was established by single intraperitoneal exposure to CS₂ on the 3rd, 4th, and 5th days after pregnancy. Endometrial tissues were collected for 24h after exposure to CS₂ for western-blot and immunohistochemical staining. Results: The number of embryo implantation was increased in NCG+CS₂ group, compared with CS₂ alone group. Day 4 of pregnancy when CS₂-exposed after 24 h, the expression of pAKT protein in NCG+CS₂ group was significantly increased (P<0.05), the expression level of pAMPK protein in NCG+CS₂ group was significantly decreased, compared with CS₂ alone group, respectively. Immunohistochemical results showed that pAKT, pAMPK, AKT and AMPK proteins were expressed in luminal epithelial cells, glandular epithelial cells and stromal cells of endometrium; Day 4 of pregnancy when CS₂-exposed after 24 h, deep staining of ATK and pAKT protein in NCG+CS₂ group, the AMPK and pAMPK protein staining became lighter. Conclusion Dietary supplementation of NCG can interfere with the embryo loss induced by CS₂ by altering the total amount of AKT/AMPK molecules.

The whole blood high shear viscosity (12.09 ± 3.46 mPa?s vs. 14.22 ± 3.51 mPa?s, t=-2.867), whole blood low shear viscosity (2.53 ± 0.68 mPa?s vs. 3.32 ± 0.71 mPa?s, t=-5.330), whole blood viscosity (1.35 ± 0.29 mPa?s vs. 1.60 ± 0.41 mPa?s, t=-3.302), erythrocyte sedimentation rate (7.10 ± 2.06 mm/h vs. 8.02 ± 2.13 mm/h, t=-2.059), fibrinogen (2.71 ± 0.53 g/L vs. 3.42 ± 0.65 g/L, t=-5.615) and erythrocyte deformation index (0.57 ± 0.16 vs. 0.71 ± 0.19, t=-3.739) of the research group were significantly lower than those of the control group (P<0.05). The incidence of adverse reactions of control group was 11.37％ (5/44), while the incidence of adverse reactions of resarch group was 6.82％ (3/44), which the difference of the incidence of adverse reactions between two groups showed no statistical significance (χ2=0.550, P=0.458). Conclusions The Tongbi capsule combined with acupuncture can reduce the degree of inflammation, and also improve hemorheology indexes of KOA patients.

Objective To investigate the impairment of intertemporal choices in adolescents with positive and negative schizophrenic symptoms.Methods 30 adolescent schizophrenia patients with positive symptoms (positive symptoms group),30 adolescent schizophrenia patients with negative symptoms (negative symptoms group)and 30 healthy controls were selected.All the subjects were investigated with intertemporalchoice Test.Results (1) Under now conditions ((37.22±30.92)％,(19.67±16.35)％,P＜0.05)),notnow conditions ((35.74±31.69)％,(19.33± 18.07)％,P＜0.05)) and overall condition ((36.48±30.44) ％,(19.50± 13.82)％,P＜0.05)),the ratio of later-large (LL) choice in negative symptoms group were significantly higher than those in the healthy controls.Under now conditions ((37.22±30.92) ％,(20.37±22.33) ％,P＜0.05)),not-now conditions ((35.74± 31.69) ％,(22.04±22.05) ％,P＜ 0.05)) and overall condition ((36.48±30.44) ％,(21.20±21.57) ％,P＜0.05)),the ratio of LL choice in negative symptoms group were significantly higher than those in positive symptoms group.There were no differences in the ratio of LL choice between positive symptoms group and healthy controls (P＞ 0.05).(2)Pearson correlation analysis showed that the Vocabulary Fluency Test of negative symptoms group was positively correlated with LL selection ratio under now conditions (r=0.411,P=0.024).Conclusion The ability of intertemporal choices in adolescents schizophrenia patients with negative symptoms is impaired remarkably,while this kind of ability is impaired unremarkable in adolescence with negative symptoms.The ability of intertemporal choices in adolescents schizophrenic patients with negative symptoms is correlated with cognitive executive function.

PURPOSE: The long non-coding RNA H19, a conservatively imprinted gene, acts as a molecular sponge for the let-7 family, which has been identified as a set of tumor suppressors. However, the combined prognostic value of H19 and let-7a signature in breast cancer patients remains unclear. METHODS: In this research we assessed the prognostic value of the combined H19 and let-7a signature in breast cancer patients by retrospectively reviewing that data of 79 patients who underwent neoadjuvant chemotherapy; we also investigated the expression and function of H19 in breast cancer cell lines in vitro. Survival data were calculated using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate survival analyses were conducted using the Cox proportional hazards regression method. As determined using X-tile, the optimal cutoff value for the risk score to assess progression-free survival (PFS) based on the combined signature was –0.1. RESULTS: Patients with an overall positive treatment response had higher let-7a and lower H19 levels. In addition, let-7a expression was negatively correlated with H19 expression. Patients with a risk score of >–0.1 had shorter overall survival and PFS. In vitro data showed that chemoresistant cell lines exhibit higher H19 and lower let-7a levels and knockdown H19 restores paclitaxel sensitivity. CONCLUSION: Our results suggest that the combined let-7a and H19 signature is a novel prognostic factor for breast cancer patients treated with neoadjuvant chemotherapy.

PURPOSE: Several accelerated partial breast irradiation (APBI) techniques are being investigated in patients with early-stage breast cancer. The present study evaluated the feasibility, early toxicity, initial efficacy, and cosmetic outcomes of accelerated partial breast intensity-modulated radiotherapy (IMRT) for Chinese female patients with early-stage breast cancer after breast-conserving surgery. METHODS: A total of 38 patients met the inclusion criteria and an accelerated partial breast intensity-modulated radiotherapy (APBI-IMRT) plan was designed for each patient. The prescription dose was 34 Gy in 10 fractions, 3.4 Gy per fraction, twice a day, in intervals of more than 6 hours. RESULTS: Of the 38 patients, six patients did not meet the planning criteria. The remaining 32 patients received APBI-IMRT with a mean target volume conformity index of 0.67 and a dose homogeneity index of 1.06. The median follow-up time was 53 months and no local recurrence or distant metastasis was detected. The most common acute toxicities observed within 3 months after radiotherapy were erythema, breast edema, pigmentation, and pain in the irradiated location, among which 43.8%, 12.5%, 31.3%, and 28.1% were grade 1 toxicities, respectively. The most common late toxicities occurring after 3 months until the end of the follow-up period were breast edema, pigmentation, pain in the irradiated location, and subcutaneous fibrosis, among which 6.2%, 28.1%, 21.9%, and 37.5% were grade 1 toxicities, respectively. Thirty-one patients (96.8%) had fine or excellent cosmetic outcomes, and only one patient had a poor cosmetic outcome. CONCLUSION: It is feasible for Chinese females to receive APBI-IMRT after breast conserving surgery. The radiotherapeutic toxicity is acceptable, and both the initial efficacy and cosmetic outcomes are good.
