Objective To study the clinical effects and changes in immune index of treating reoccurring respiratory tract infection in children by combining zinc gluconate granula and decoction of four mild drugs.Methods 135 RRI children patients were randomly divided into treatment group which has 68 cases and control group which has 67 cases.The control group are given regular western anti-infection treatment while the treatment group are given,in addition to that,zinc gluconate granule and decoction of four mild drug.Both groups are observed for 3months and then compare the effects and changes of IgG、IgA、IgM before and after the treatment.Results 48 out of 68 cases in treatment group have results of excellence,15 cases have effects and 5 cases show no effects,so the effective rate is 92.64%;While 33 out of 67 cases in control group have results of excellence,10 cases have effects and 24 cases show no effects,so the effective rate is 64.18%.Comparing these two groups,the treatment group gets better effects than the control group(P

Although the treatment has made great progress in breast cancer, there are still many problems. For example, primary or secondary on chemotherapy drug resistance and the limitation of treatment in triple-negative breast cancer. So, targeted therapy has become a new strategy to improve this situation. Previous studies showed that the occurrence of breast cancer may be related to the activation of PI3K/Akt/mTOR signaling pathways, and mTOR is an index to judge the prognosis. Parts of breast cancers can obtain clinical benefit with mTOR inhibitors, and it might be a potential treatment target in breast cancer.

Objective:To investigate psychological needs, state of mind and psychological feeling, and analyze the related factors.Method:2000 subjects over 60 years of age in Beijing are evaluated with the part of psychological needs of the Life State Inventory for Residents of Beijing.Results:The intergeneration relationship, state of mind and psychological feeling of the elderly were well. They were related each other closely. The state of mind improved with educational level and that of male were better than female. Most of the elderly considered that the effect of the state of mind on the quality of life was obvious. The psychological feeling declined with aged and improved with educational level. The satisfaction degree of economy and care, filial obedience, health were related to life satisfaction degree, state mind and psychological feeling.Conclusion:Psychological needs of the elderly were satisfied in general. The state of mind was one of the important factors on the quality of life.

Objective To define the patterns of local extension and nodal involvement in patients with early stage nasal NK/T-cell lymphoma, and to improve the delineation of clinical target volume.Methods Two hundred and twenty-two patients consecutively diagnosed with nasal NK/T-cell lymphoma were reviewed.All patients had stage Ⅰ E/Ⅱ E diseases.CT/MRI images were reviewed to determine the local invasion of adjacent organs or structures and involvement of lymph node.Results 143 of 222(64%) patients had primary tumor extended into adjacent organs or structures from nasal cavity.According to the incidence rates of tumor extension, the involved organs or structures were subclassified into three subgroups:high risk (≥40%):ethmoid sinus (60%) and maxillary sinus (55%);intermediate risk (5%-40%):nasopharynx (39%), skin (22%), oropharynx (12%), orbit (10%), and hard palate (10%);and low risk (≤5%):sphenoid sinus (3%), soft plate (3%),frontal sinus (3%) and skull base (1%).Cervical lymph node metastasis occurred in 16%(36/222) of the patients and these patients were staged as Ⅱ E.Thirty-three patients with stage Ⅱ E disease had available images and were analyzed for the pattern of nodal involvement.Submandibular or submental (57%) and the upper cervical lymph nodes (57%) were the most commonly involved sites of nodal region.For the 24 patients with primary tumor located in the unilateral nasal cavity, 54% presented with contralateral cervical lymph node metastasis.Whereas for the 9 patients with primary tumor located in the bilateral nasal cavity, 57% had bilateral cervical lymph node metastasis.For the 88 patients with extensive stage Ⅰ E disease who did not receive irradiation to the cervical lymph node, only one patient (1%) had disease relapse in cervical lymph node.Furthermore, all patients with disease extended to nasopharynx (n= 23) or oropharynx (n= 8) did not receive prophylactic cervical lymph node irradiation, and none of them developed cervical lymph node relapse.Conclusions The delineation of clinical target volume for early stage nasal NK/T-cell lymphoma should be determined by the risk of involvement of paranasal structures and cervical lymph node.Prophylactic neck irradiation is not recommended for patients with stage Ⅰ disease.

Objective To evaluate the clinical features, treatment outcome, and prognostic factors in patients with primary Waldeyer’ s ring diffuse large B?cell lymphoma (WR?DLBCL). Methods This study included 200 patients with a confirmed diagnosis of primary WR?DLBCL admitted to our hospital from 2000 to 2013, who consisted of 50 stage I patients, 125 stage II patients, and 25 stage III?IV patients. Most patients received 4?6 cycles of CHOP or CHOP?based chemotherapy with or without involved field radiotherapy (Waldeyer′s ring+cervical lymph node region). Results The 5?year sample size was 71. The 5?year overall survival (OS), progression?free survival (PFS), and locoregional control (LRC) rates for the whole group were 78%, 72%, and 87%, respectively. In the 175 early stage patients, chemoradiotherapy resulted in significantly higher OS, PFS, and LRC than chemotherapy alone (86% vs. 70%, P= 0?? 001;84% vs. 58%, P= 0?? 000;97% vs. 66%, P= 0?? 000). Univariate analysis showed that age, tumor size, stage, lactate dehydrogenase level, and International Prognostic Index were prognostic factors for OS, PFS, and LRC ( P= 0?? 000?0?? 036), while the prognostic factors for PFS also included Eastern Cooperative Oncology Group score and cervical nodal involvement (P= 0?? 018). Multivariate analysis showed that age and stage were prognostic factors for OS and LRC (P= 0?? 003?0?? 022), and age was the prognostic factor for PFS (P= 0?? 000). Conclusions WR?DLBCL has distinct clinical features and favorable prognoses. For early stage patients, combined?modality therapy results in significantly higher OS, PFS, and LRC.

Objective To evaluate the value of radiotherapy following rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone ( R?CHOP )?based chemotherapy for patients with early?stage Waldeyer’ s ring diffuse large B?cell lymphoma ( WR?DLBCL). Methods Eighty?three patients diagnosed with early?stage WR?DLBCL who were admitted to our hospital from 2000 to 2013 were enrolled in the study. In these patients, twenty?five had stageⅠdisease and fifty?eight had stageⅡdisease. All patients received R?CHOP?based chemotherapy with ( n= 62 ) or without ( n= 21 ) involved?field radiotherapy ( Waldeyer’ s ring plus cervical lymph nodes ) . The overall survival ( OS ) , progression?free survival ( PFS) , and local?regional control ( LRC) rates were calculated using the Kaplan?Meier method. The univariate analysis was performed using the log?rank method. The multivariate analysis was performed using the Cox regression model. Results In all patients, the 5?year sample size was 18;the 5?year OS, PFS, and LRC rates were 89%, 84%, and 90%, respectively. According to the univariate analysis, patient age greater than 60 years, an increased lactate dehydrogenase level, Eastern Cooperative Oncology Group ( ECOG ) performance status no less than 2, and International Prognostic Index ( IPI ) no less than 2 were poor prognostic factors. Patient age greater than 60 years, a tumor size no less than 5 cm, ECOG performance status no less than 2, and IPI no less than 2 were influencing factors for PFS and LRC rates. In addition to the treatment with rituximab, patients treated with consolidative radiotherapy had significantly higher PFS and LRC rates (94% vs. 58%, P=0?003;100% vs. 61%, P=0?000) as well as slightly higher OS rate ( 9 4%vs . 7 1%, P=0?0 6 3 ) than those treated without radiotherapy . Conclusions Consolidative radiotherapy following R?CHOP?based chemotherapy significantly improves PFS, LRC, and probably OS rates for early?stage WR?DLBCL. This conclusion still needs to be confirmed by prospective studies with a large sample size.

Objective This study aimed to evaluate the prognostic value of regional lymph node spread in patients with stage Ⅱ nasal-type NK/T-cell lymphoma of the upper aerodigestive tract (UADT-NKTCL).Methods From 1987 to 2013,a total of 97 patients with newly-diagnosed stage Ⅱ UADT-NKTCL were retrospectively reviewed.Primary tumors were located in the nasal cavity (n=52) or extranasal UADT sites (n=45).The majority of patients were treated with primary radiotherapy.Sixty-five patients were treated with combined modality therapy (CMT),and 32 patients were treated with radiotherapy alone (n=27) or chemotherapy alone (n=5).The Kaplan-Meier method was used to calculate the survival rate,and the log-rank test was used for survival difference analysis and monovariate prognostic analysis.The Cox regression model was used to multivariate prognostic analysis.Results The 5-year overall survival (OS) and progression-free survival (PFS) rates for all stage Ⅱ patients were 57% and 49%,respectively.The presence of a lower neck lymph node (defined as extension below the caudal border of the cricoid cartilage) was significantly associated with poor outcomes on univariate analysis and maintained significance on multivariate analysis.The median survival for patients with lower neck lymph node was 19.3 months and the 2-,5-years OS rates were 28% and 11%(P=0.000).For stage Ⅱ patients,CMT significantly improved survival.The 5-year OS and PFS rates were 64% and 52% for CMT,compared with 40.4%(P=0.006) and 42% for single modality therapy (P=0.088).Conclusion The level of regional lymph node is a powerful prognostic factor for stage Ⅱ UADT-NKTCL.The involvement of low neck lymph node is significantly associated with poorer survival outcomes.

Objective To investigate the safety and acute toxicities of intraoperative electron radiotherapy for patients with abdominal tumors.Methods From May 2008 to August 2009, 52 patients with abdominal tumors were treated with intraoperative electron radiotherapy,including 14 patients with breast cancer,19 with pancreatic cancer,3 with cervical cancer, 4 with ovarian cancer, 6 with sarcoma, and 6 with other tumors.Fifteen patients were with recurrent tumors.The intraoperative radiotherapy was performed using Mobetron mobile electron accelerator, with total dose of 9 - 18 Gy.In all, 29, 4 and 19 patients received complete resection, palliative resection and surgical exploration, respectively.The complications during the operations and within 6 months after operations were graded according to Common Terminology Criteria for Adverse Events v3.0 (CTC 3.0).Results The median duration of surgery was 190 minutes.Intraoperative complications were observed in 5 patients, including 3 with hemorrhage, 1 with hypotension,and 1 with hypoxemia, all of which were treated conservatively.The median hospitalization time and time to take out stitches was 12 and 13 days, respectively.And the in-hospital mortality was 4% (2/52).Twentyfour patients suffered post-operative adverse events, including 3 postoperative infections.With a median follow-up time of 183 days, 20% of patients sufferred from grade 3 to 5 adverse events, with hematological toxicities being the most common complication, followed by bellyache.Grade 1 and 2 toxicities which were definitely associated with intraoperative radiotherapy was 28% and 4%, respectively.None of grade 3 to 5 complications were proved to be caused by intraoperative radiotherapy.Conclusions Intraoperative electron radiotherapy is well tolerable and could be widely used for patients with abdominal tumors, with a little longer time to take out stitches but without more morbidities and toxicities compared surgery alone.
