This paper described the practice of real-time booking registration, in which the patients may freely choose their visit time points, by such means as the outpatient clinic, website, telephone or short messaging. Such booking registration is an important measure to improve service quality at outpatient clinics; information technology is a prerequisite for real-time booking registration; pooling of outpatient ID number resources is key to setting up the booking registration; the prepaid card deposit practice makes booking registration more efficient; enhanced management for supporting services safeguards booking registration; cooperation with qualified third parties is an effective way to accomplish booking registration in a convenient manner. This paper also probed into other issues in relation to real-time booking registration.

Objective To study the male reproductive ability of male rats with Toxoplasma gondii ( Tg) infection and investigate the variation of Toxoplasma infection in seminal plasma of infertile patients and explore its mechanism. Methods Thirty SD rats were randomly divided into 3 groups. The rats in the Toxoplasma infection group were administrated intraperitoneally with tachyzoites of Tg. in a dosage of 2 × 10~ 5/ml(2ml) , the rats in the treated group were administered with the same dosage of the tachyzoites and from the second day after the infection they were treated with 200 mg/kg azithromycin for 7 days, and the normal group was given physiological saline. Nine weeks after the infection, the serum sex hormone level, number,vitality, activity and quantity of spermatozoa and activities of enzymes in testa's of the testicular tissues were determined in the male rats. The female rats infected with Tg were matched with normal female rats at a ratio of 1: 2 for one week, and on the 21st day of pregnancy, the number of corpora luteum, sex ratio and the weight, body length and tail length of fetus were measured. The ELISA method was used todetermine the seminal plasma's anti-Tg IgG antibody of the 169 patients with infertility and 35 males with normal fertility. Meanwhile the NO levels in their semina were determined by means of nitric acid reducase. Results The number, activity .vitality, serum level of sex hormones were all lower in the infected rats than those in the normal and treated groups. The number of fetus in the pregnant rats matched with the infected male rats was significantly fewer, but the average body weight, body length, tail length of the fetuses and sex proportion showed no significant difference in comparison with those of the control group. The anti-Toxoplasma gondii antibody positive rate in the masculine infertility patients was 18.35% , being significantly higher than 2. 86% in the normal fertility group(P < 0.05 ). The mean NO level in the semina from the infertility group was (146.68 ± 38. 87) μnol/L , which was significantly higher than (84.92 ± 26.72) μnol/L( P < 0.01) in the fertility group. Conclusion Toxoplasma gondii infection can cause certain influences on the male reproductive ability.

Objective To evaluate the effect and safety of combined therapy of paclitaxel and gemcitabine for anthracycine(ANT)-resistant advanced breast cancer(ABC).MethodsFrom May 2000 to Aug 2004,twenty six patients with ANT-resistant ABC were treated with this combined regime.The median chemotherapy cycles were 2.5(range from 2 to 3 cycles).ResultsOf 26 patients, there were 3 complete(11.5%) and 11 partial(42.3%) responses for an overall response rate of 53.8%. Eight cases remained stable (30.8%) and 4 progressive (15.4%). The median survival time was 18 months. The median time to progression was 7 months. The main toxic reaction included bone marrow depression, liver function damage, alopecia, mucositis and peripheral neurotoxicity. ConclusionsCombined medication of gemcitabine and paclitaxel is effective in therapy of ANT-resistant advanced breast cancer with acceptable toxicity.

The transcription activity of ectogenic human carcinoembryonic antigen (CEA) promoter in lung adenocarcinoma cells A549 was investigated for the further gene-targeting therapy. The reporter gene green fluorescent protein (GFP) driven by CEA promoter and human cytomegalovirus (CMV) promoter were relatively constructed and named plasmid pCEA-EGFP and pCMV-GFP respectively. The intensity of fluorescence was detected by fluorescence microscope and flow cytometry analysis after the pCEA-GFP and pSNAV-GFP plasmids were transfected into A549 cells through liposome respectively. The results showed (4.08+/-0.63) % of the A549 cells transfected with pCEA-AFP plasmid expressed, significantly lower than that of the A549 cells transfected with pCMV-GFP [(43.27+/-3.54) %]. It was suggested that ectogenic human CEA promoter in lung adenocarcinoma cells A549 was weakly expressed. The distinct specificity of CEA promoter in CEA high expression cells was regarded as a tool in selective gene therapy, but the transcription activity of ectogenic human CEA promoter was needed to increase in the future.

Objective To investigate the treatment outcome and failure in patients with primary mediastinal large B-cell lymphoma(PMBL). Methods Between Jan. 1992 and Oct. 2006, a total of 46 patients with pathologically confirmed PMBL were reviewed, including 14 with Ann Arbor Stage I disease, 23 with Stage Ⅱ disease,3 with Stage Ⅲ disease and 6 with Stage Ⅳ disease. Stage Ⅰ+Ⅱ disease was present in 80% of the patients. All patients were treated with chemotherapy ,and 29 also received radiotherapy. Twenty-seven patients(59%) were treated with first generation regimen(CHOP),9(20%) with third generation regimens (MACOP-B, ProMACE/CytaBOM, m-BACOD, or ProMACE-MOPP), and 10(22%) with high-dose chemotherapy (HDCT/APBSCT). Rituximab was administered to 16 patients (35%). For most patients who received radiotherapy,an involved field was used with a median dose of 45 Gy in 23 fractions.Results The rate of complete remission, partial remission and progression disease was 41%, 30% and 24% ,respectively. The 5-year overall survival rate(OS) for all patients was 35%. The 2- and 5-year OS was 79% and 63% for stage Ⅰ+Ⅱ and 51% and 0 for stage Ⅲ+Ⅳ ,respectively(X2=4.35 ,P=0. 037).The 2-year progression free survival rate was 63 % and 11%, respectively (X2=17.77, P=0.1300). The 5-year OS was 80% for the patients with CR,50% for those with PR,and 0 for those with progression disease(X2= 19.58 ,P=0.003 ). With a median follow-up of 22 months, progression disease and relapse occurred in 19 patients. Conclusions Survival of patients with advanced stage PMBL is poor. Further studies areneeded to confirm the optimal treatment. Radiotherapy often plays a pivotal role in local control.

Objective To analyze the acute and late toxicities in patients with prostate cancer trea-ted with hypofractionated intensity-modulated radiotherapy (IMRT). Methods Between June 2006 and June 2008, 37 patients with prostate cancer were treated with hypofractionated IMRT. The clinical target vol-ume (CTV) was the prostate, seminal vesicles and pelvic lymph nodes in 24 patients, the prostate and semi-hal vesicles in 12, and only the tumor bed in 1. The dose per fraction was 2.3 - 2.8 Gy, with 2.7 Gy in 26 patients. The minimal dose was 62.5-75.0 Gy to the prostate and seminal vesicles, and 50 Gy to the pelvic lymph nodes. Results The median follow-up was 14 months. None of the patients experienced grade 4 a-cute gastro-intestinal (GI) toxicity. Grade 1, 2 and 3 acute GI toxicity occurred in 24.3%, 35.1% and 2.7% of the patients, respectively. The rectal V50>27% and V55>20% were highly significantly associat-ed with grade ≥1 acute GI toxicity. Grade 1,2 and 3 acute genitourinary (GU) toxicity occurred in 68%, 0% and 3% of the patients, respectively. The bladder V50> 10% was significantly associated with grade ≥1 acute GU toxicity. The incidence of late GI toxicity was low. No grade ≥3 late GI toxicity was observed. The incidence of late grade 1 and 2 GI toxicity was 24% and 5%, respectively. The rectal V65> 10% was highly significantly associated with grade ≥1 late GI toxicity. No late grade 4 GU toxicity was observed. The incidence of grade 1, 2 and 3 late GU toxicity was 49%, 11% and 3%, respectively. Grade ≥2 late GU toxicity was correlated with V40, V50 and mean dose of the bladder. Conclusions Acute and late toxicity of hypofractionated IMRT is acceptable in patients with prostate cancer.

Objective To analyze the clinical features and treatment outcomes of extranodal diffuse large B-cell lymphoma(DLBCL). Methods Ninety-nine consecutively diagnosed patients with extranodal DLBCL were reviewed. All patients were confirmed by a combination of morphologic and immunohistochemi-cal evaluation. The primary sites of extranodal DLBCL were the gastrointestine(n = 32) ,central nerve system (CNS)/testis(n=14) ,and other sites (n = 53). Results Extranodal DLBCL was characterized by a pre-dominance in old males,less frequency of B symptorns,a large proportion of stage Ⅰ-Ⅱ disease and low in-ternational prognostic factor(IP1) score. The 5-year overall survival(OS) rate for all patients was 78.9%. The corresponding OS rate was 82.5% for gastrointestinal origin, 37.0% for CNS and testis origin and 74.6% for other organ origin, respectively. On univariate analysis, performance status, IPI score and more than one extranedal site involvement were the prognostic predictors for 5-year OS. Conclusions Being a heterogeneous group of lymphomas, extranedal DLBCL has good prognosis except those derived from the CNS and testis.

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 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 compare target dosimetric distribution and normal tissue radiation between different static intensity?modulated radiation therapy ( IMRT) plans and volumetric modulated arc therapy ( VMAT) and to identify the best IMRT plan for patients with primary mediastinal B?cell lymphoma ( PMBCL) . Methods A total of 16 patients ( 8 males and 8 females) with early?stage ( Ann?Arbor stageⅠ) PMBCL were enrolled in this study,with doses of 45 Gy for primary gross tumor volume ( PGTV) and 40 Gy for planning target volume (PTV).Four plans were designed for each patient,consisting of static IMRT (5F?IMRT,7F?IMRT,9F?IMRT) and VMAT,and the target dosimetric distribution,normal tissue radiation dose,and efficiency of each plan were evaluated. The difference of dose was analyzed by analysis of variance. Results The mean conformity index ( CI) and homogeneity index ( HI) for PGTV in 5F?,7F?,9F?IMRT and VMAT were 1. 01 and 1. 10, 1. 01 and 1. 10, 1. 01 and 1. 10, and 1. 01 and 1. 11 ( P= 0. 963 and 0. 843) ,respectively,while these two indices for PTV were 1. 04 and 1. 22,1. 03 and 1. 19,1. 03 and 1. 17, and 1. 08 and 1. 14( P=0. 964 and 0. 969) ,respectively. The parameters of volume and dose were similar on normal tissue ( P= 0. 192?1. 000 ) . The treatment time and number of monitor units in 9F?IMRT were significantly higher than those in other static IMRT plans and VMAT ( P=0. 000,0. 000) ,and among these plans,VMAT had the lowest number of monitor units ( 13 345. 0 MU) and the shortest treatment time ( 5. 9 min) . Conclusions The target volume coverage of 7F?and 9F?IMRT is better than that of 5F?IMRT and VMAT.For early?stage PMBCL,VMAT is not superior to IMRT in terms of dosimetry,especially with a larger area of low?dose radiation to the breast,but it is highly efficient in practice.
