Objective To evaluate the prognostic value of iASPP for nasopharyngeal carcinoma (NPC).Methods One hundred and thirty patients with nasopharyngeal carcinoma were initially diagnosed and treated between January and December 2012 in Department of Radiation Oncology of the First Affiliated Hospital of Guangxi Medical University.The clinical staging was classified according to the cancer staging criteria 2009 AJCC/UICC.All patients were treated by IMRT.Cisplatin-based concurrent chemotherapy was given to patients with stages Ⅲ-ⅣB disease.Immunohistochemistry was used to detect the expression of iASPP in the carcinoma tissues,and the clinicopathological features were compared among the patients with different expressions of iASPP.Furthermore,the relationship between the expression of iASPP and the efficacy in patients was explored.Results Of 130 patients,positive expression of iASPP was observed in 86 patients (66.2％),and negative expression in 44 patients (33.8％).There was significant difference in the positive expression rate of iASPP among the patients with different N-stage and clinical stages(x2 =7.565,4.947,P ＜ 0.01).At three months after treatment,no significant difference was found in the response rate of tumor with different expression of iASPP.In univariate analysis,the expression of iASPP was significant predictor of 3 year-DMFS (x2 =4.335,P =0.037) and PFS (x2 =6.640,P =0.01).Furthermore,N-stage was significant predictor of 3y-DMFS (x2 =8.058,P =0.005),PFS (x2 =9.554,P =0.002) and OS (x2 =6.987,P =0.008),respectively.By using multivariate Cox analysis,the expression of iASPP and N-stage was independent prognostic factors for PFS (x2 =4.336,5.228,P ＜ 0.05),respectively.Conclusions Positive expression of iASPP may be a poor prognostic factor for NPC patients.

Objective To evaluate the short- and long-term efficacy of microwave hyperthermia combined with chemoradiotherapy in treating metastatic nasopharyngeal carcinoma to the cervical lymph nodes. Methods A total of 154 cases of stage N2-N3 nasopharyngeal carcinoma (1992 stage system) were randomized into two groups: group A (76 cases, treated with microwave hyperthermia combined with chemoradiotherapy) and group B (78 ca-ses, treated with chemoradiotherapy alone). Both groups received 1 to 2 cycles of chemotherappy with cisplatin and 5-fluorouracil and then received regular radiotherapy. The total doses of radiotherapy were 70-78 Gy/35-39 f, 47-51 d for the primary loci of nasopharynx and 68-72 Gy/34-36 f,46-50 d for the metastatic loci in the neck. Group A received microwave hyperthermia on the metastatic cervical node at the beginning of radiotherapy, with the micro-wave hyperthermia administered for 45 min every time,two times a week, totaling 8 to 14 times. Results The complete extinction rates of neck metastatic carcinoma were 80.3% and 61.5% , respectively, in groups A and B (P<0.05). The overall response rates of neck metastasis in the two groups were 100% and 96.2% , respective-ly. When the cervical lymph node metastasis disappeared, the radiotherapy doses in group A and B were (45.8 ± 5.46 ) Gy and (58.8±5.03 ) Gy, respectively (P<0.01). The 5-year local control rates of cervical lymph node in group A and B were 97.4% and 76.9%(P<0.05 ), respectively. The one-, three- and five- year survival rates were 97.4% , 76.3% and 59.2% respectively, in group A, versus 93.6% (P>0.05) ; and 52.6% (P< 0.01) and 41.0% (P<0.05), respectively, in group B. Conclusions Microwave hyperthermia combined with chemoradiotherapy can elevate the complete extinction rate of cervical lymph node metastasis of nasopharyngeal carcinoma and reduce the radiotherapy dose needed of effective control. The 5-year local control rate of cervical lymph node metastasis in combined therapy group is superior to that in the chemoradiotherapy alone group,and can elevate the long-term survival rate of patients.

Objective To evaluate long-term efficacy of microwave hyperthermia combined with chemoradiotherapy for nasopharyngeal carcinoma (NPC) with cervical lymph node metastasis. Methods A total of 154 patients with stage N2 or N3 NPC ('92 staging system) were randomized into two groups:microwave hyperthermia combined with chemoradiotherapy (Group A, 76 cases) and chemoradiotherapy alone (Group B, 78 cases). Both of the two groups received 1 -2 cycles of chemotherapy of cisplatin and 5-fluorouracil, followed by conventional radiotherapy of 70 - 78 Gy in 35 - 39 fraction to the nasopharynx and 68 -72 Gy in 34 - 36 fractions to the neck. Group A received microwave hyperthermia to the metastatic cervical nodes at the beginning of radiotherapy. The hyperthermia was given as 45 min every time, twice a week for 8 - 14 times totally. Results The 5-year complete response rates of cervical lymph nodes in group A and B were 97% and 77% (x2 = 14. 24,P<0. 01). The distant metastasis rates in the two groups were 37% and 44% (x2 = 0. 73, P > 0. 05). The disease-free survival rates were 51% and 21% (x2 = 15.91, P <0. 01). The 5-year overall survival rates were 59% and 41%, respectively (x2 = 5.09, P < 0. 05).Conclusions For patients with stage N2 or N3 NPC, microwave hyperthermia combined with chemoradiotherapy can improve the complete response, disease-free survival and overall survival.

OBJECTIVE To investigate the distribution of serum markers of transfusion-transmitted infections in hospital,and analyze the clinical values in the control of nosocomical infection. METHODS The serum markers of transfusion-transmitted infections from 21 605 hospitalized cases,such as HBsAg,anti-HCV,anti-HIV,and RPR were detected. RESULTS The positive rate of HBsAg and anti-HCV was 9.78% and 1.70%,respectively.The positive anti-HIV was detected in 13 cases by the primary screening test for HIV,and the 13 cases were reconfirmed by the reconfirmation laboratory of CDC in Hunan Province.The positive RPR was in 4 cases,the same as of TPHA.There were 2 582 positive cases of the four indexes(HBsAg,anti-HCV,anti-HIV and RPR),the total positively detectable rate was 11.95%,which was obviously higher than 7.6% of normals(P

Objective To investigate knowledge, attitude and practice (KAP) on schistosomiasis control in transmission-interrupted areas in order to provide basis for making out intervention strategies of preventing re-epidemic of schistosomiasis. Methods A questionnaire survey was carried out for residents’ KAP on schistosomiasis control in the transmission-interrupted areas. A total of 608 residents were surveyed. Results The residents’ understanding rates of each item of schistosomiasis control were under 25.00% without exception. Residents refusing schistosomiasis examination, never surveying snails and never reporting snails accounted for 52.30%, 95.23% and 97.86% respectively. Conclusions Residents treat schistosomiasis control with indifference in transmission-interrupted areas. Therefore, intervention strategies of pertinent health education should be adopted to improve residents’ compliance to schistosomiasis examination and snail survey and report, and to prevent schistosomiasis re-epidemic.

Objective: To study the changes of inflammatory response and apoptosis in parotid gland tissues of rats after X-ray irradiation, and to explore the protective effect and possible mechanism of Sarcandra glabra on radiation-induced parotid injury in rats. Methods: A total of 120 male rats were randomly divided into 5 groups(24 for each): control group, single irradiation group, radiation combined with a high(26.8 g·kg^-1·d^-1), moderate(13.4 g·kg^-1·d^-1) and low(6.7 g·kg^-1·d^-1) dosage of Sarcandra glabra group. The parotid gland of rats in the irradiation group received 15 Gy X-ray. Rats in each group were anesthetized with 2% pentobarbital sodium (0.16 ml/100 g) at 10, 40 and 70 d after irradiation and blood was collected from abdominal aorta. ROS levels in blood serum of each group were detected on the 10th, 40th and 70th days after irradiation. After parotid gland tissue was taken, the pathological changes and ultrastructural changes were observed by hematoxylin-eosin (HE) staining and transmission electron microscopy, respectively. The expression level of TNF-α in parotid gland tissue was detected by immunohistochemistry, and apoptosis of parotid cells was detected by TUNEL assay. Results: The content of ROS and the expression of TNF-α protein in the single irradiation group were simultaneously increased compared with the control group (t=-24.723, -35.013, -19.515, P<0.05; t=-13.563, 43.519, -15.249, P<0.05), while they were reduced by Sarcandra glabra in a dosage dependent manner, especially in the high dosage group of Sarcandra glabra (t=5.295, 8.138, 6.545, P<0.05; t=10.093, -7.868, 10.539, P<0.05). In the control group, the parotid gland tissue structure was intact, without congestion, exudation, edema, etc. For the single irradiation group, the parotid gland tissue became hyperemia, edema and inflammatory cell infiltration at 10 d after irradiation followed by fibrosis at 40 d after irradiation. These pathological alterations in the parotid gland tissue were significantly recovered when the rats were treated with Sarcandra glabra before irradiation, and the tissue damage was negatively correlated with drug dosage. TUNEL assay showed that the apoptosis rate of parotid gland cells in the single irradiation groups was higher than that in the control group (t=-4.639, -3.979, P<0.05). Conclusions Sarcandra glabra protects parotid gland from radiation damage by scavenging radiation-induced ROS and declining inflammatory response, and thus it may be applied as a potential protective agent for radiation injury.

Objective To evaluate the treatment efficacy,toxicities and prognostic factors of nasopharyngeal carcinoma ( NPC ) treated with intensity modulated radiation oncology ( IMRT ).Methods Between January 2006 and August 2008,300 patients with pathologically diagnosed NPC from 6 center received IMRT.The number of patients with stage Ⅰ,Ⅱ,Ⅲ and Ⅳa+b disease (UICC/AJCC 2002 staging system) were 6,45,141 and 108,respectively.The prescription doses were as follows:70-74 Gy/30f toplanning target volume of primary nasopharynx tumor ( PTVRλ),68-70 Gy/30f to planning target volume of positive lymphnode (ptvnd),60-64 Gy/30f to higher risk region (PTV1),50-54 Gy/30f to lower risk region (PTV2).Patients with stage Ⅲ and Ⅳa+b disease also received cisplatin-based chemotherapy.Cox method was used for Multivariate analysis.ResultsThe follow-up rate was 99.7％.The 4-year rate of local control,regional control,metastasis-free survival (DMFS),disease-free survival (DFS) and overall survival (OS) was 94.0％,95.5％,87.4％,80.8％,86.1％,respectively.Mucositis was the most severe acute toxicity,with 18.0％grade 1,48.7％grade 2,33.3％grade 3.No patient suffered from grade 4mucositis.Xerostomia was the most common late toxicity,with 12.0％ grade 0,75.7％ grade 1,12.3％grade 2.No grade 3-4 xerostomia was observed.There were 18,15 and 42 patients failed in local,regional and distant metastasis,respectively.Multivariate analysis showed that N stage was the only prognostic factor for OS (x2 =5.17,P=0.023),DMFS (x2 =6.91,P=0.009) and DFS (x2 =8.15,P=0.004) in these patients.ConclusionsIMRT can improve the treatment efficacy of NPC.The acute and late toxicities were tolerated.Distant metastasis becomes the main treatment failure.N stage is a significant prognostic factors.

OBJECTIVE: To observe the change of serum homocysteine (Hcy) and anti-citrullinated peptide (CCP) antibody concentration in depression rat model induced by chronic unpredictable mild stress (CUMS), and to explore the immunologic mechanism of depression and the relation between depression and its autoimmunity. METHODS: Sixty adult male SD rats were randomly divided into 2 groups, 30 rats in each group, which were divided into 3 subgroups: a normal control group, a model group and a fluoxetinetreated group. The depression rat model was established under CUMS and seperated feeding, after which, open field, sugar consumption and forced swimming test were applied in the first group. After the blood was taken in the second group of rats through heart puncture, the level of serum Hcy was detected by enzymatic cycling assay and serum anti-CCP antibody by ELISA. RESULTS: Compared with the control group and the fluoxetine treatment group, spontaneous activity and sucrose consumption and preference percentage of the rats in the model group significantly reduced, while the immobility time in forced swimming test and the level of Hcy and anti-CCP antibody in the rat serum significantly increased. CONCLUSION Immunity inflammation and autoimmune reaction exist in CUMS depression model rats, and fluoxetine treatment can improve these immune response.
