Objective To analyze the effects of overexpressed iASPP on breast cancer cell line MCF-7. Methods The iASPP cDNA was obtained from breast carcinoma tissue by RT- PCR. The breast cancer cell line MCF-7 that overexpressed iASPP was established by stable transfection and G418 selection. The proliferation and apoptosis of the MCF-7 cells that overexpressed iASPP after exposure to cisplatin were detected by MTT and flow cytometry. Results The MCF-7 cells that overexpressed iASPP were successfully constructed. Overexpressed iASPP could significantly decrease the apoptosis rate of MCF-7 cells exposed to cisplatin and weaken the inhibitory effects of DDP on the proliferation of MCF-7 cells. Conclusion Overexpressed iASPP attenuates the sensitivity of human breast cancer cell line MCF-7 to cisplatin.

OBJECTIVETo investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

CONCLUSIONCompared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.

ObjectiveTo investigate the factors related with curative effect and prognosis of postoperative radiotherapy for nasal and paranasal sinuses carcinoma.MethodsThe data of 95 patients with nasal and paranasal sinuses carcinoma and received postoperative radiotherapy were reviewed retrospectively. Kaplan-Meier method was used to analyze the survival, Logrank test used to compare the differences between different groups. Multivariate analysis was performed by Cox proportional hazard model.ResultsThe overall 1, 3, 5, 10-year survival rates of 95 patients were 84.2%, 50.5%, 44.2% and 20% respectively. Univariate analysis showed that sex, age, operative modality and tumor dose were not related with survival. Histological and clinical stages were related with survival. Multivariate analysis indicated that histological and clinical stages were independent prognostic factors. The follow-up results showed that visual disturbance, xerostomia, dysaudia were the major side effects.ConclusionPostoperative radiotherapy can improve therapeutic effect in the treatment of nasal and paranasal sinuses carcinoma, and histological and clinical stages are the independent prognostic factors effecting prognosis.

ObjectiveTo explore the efficacy of medication management and symptom management skills-training for preventing schizophrenics' relapse and rehabilitating their mental handicaps.Methods133 subjects were randomly assigned to the skills training group and the control group. Both groups received the same treatment, but the skills training courses were given to the skills training group for the first twenty weeks. One-year follow-up was carried out. All subjects were evaluated with standard rating scales and self-complied drug treatment compliance rating scale. Results128 subjects had completed the research. The skills training group demonstrated clinical results significantly superior to those of the control group on overall improvement according to the total score of the drug treatment compliance rating scale, the rate of relapse, the rate of re-hospitalization and the rate of effectiveness of minimizing handicap(147.9±53.2 vs. 90.4±16.3, 146.1±20.0 vs. 91.7±16.7;12.5% vs. 55%; 3.2% vs. 39.6%;86.5% vs. 26.5%, P<0.01).Conclusions The two kinds of skills training are effective in both preventing the relapse of schizophrenics in the community and minimizing their handicap.

OBJECTIVETo analyze the impact of radical surgery with different extent of lymph nodes dissection on the prognosis of colorectal carcinoma patients and to see if lymph nodes adjacent to mesenteric artery root should be excised.

METHODSData of 1409 cases with colorectal carcinoma treated in Shanghai Cancer Hospital during 1985-2000 were collected. These patients had primary colorectal carcinoma treated by radical surgery with different extent of lymph nodes excision. They were divided into two groups: in group D3 the lymph nodes adjacent to mesenteric artery root were excised (n = 857), while in group D2 (n = 552) were not. The time of follow-up was 6 approximately 289 months (median: 48 months).

RESULTSThe 1-, 3-, 5-, 10-year total survival rates (TS) in group D3 patients were 90.3%, 81.4%, 77.0% and 73.0%, respectively. The 1-, 3-, 5-, 10-year tumor-free survival rates (TFS) in group D3 patients were 89.9%, 79.4%, 74.5% and 70.3%, respectively. In group D2 patients, the 1-, 3-, 5-, 10-year TS were 91.04%, 84.12%, 79.33% and 76.17%, and those of TFS were 90.0%, 82.7%, 76.0% and 71.8%, respectively. The differences in TS and TFS in the two groups of patients were not significant according to Kaplan-Meier analysis (P > 0.05). During the follow-up period, 42 patients in group D3 had local recurrence (4.9%), while in group D2 the rate of local recurrence was 5.4% (P > 0.05). Metastases developed in 79 cases in group D3 and in 60 cases in group D2 (P > 0.05). Multivariate analysis revealed that the excision of lymph nodes adjacent to mesenteric artery pedicle did not statistically correlate with recurrence, metastasis and survival time after radical operation of colorectal cancer.

CONCLUSIONExcision of lymph nodes adjacent to the mesenteric artery root has no significant impact on prognosis and is unnecessary in the radical surgery for colorectal carcinoma.

OBJECTIVETo summarize the experience and investigate better method on treatment of high-grade soft tissue sarcomas of crura in youth.

METHODSSix young cases suffered from high-grade soft tissue sarcomas of crura were treated by interpolatory chemotherapy using vindesine 4mg or vincristine 2 mg combined with cisplatin 40 - 60 mg and 4'-Epidoxorubicin (4'-epi-ADM) 50 - 80 mg. There were 3 males and 3 females, and their ages rang from 12 to 23. The primary tumor locations were: calf in 4, thigh in 1, popliteal fossa in 1. The pathological type of these 6 cases were: 1 small round cell tumor from soft tissue, one rabdomyosarcoma, one alveoliar soft part sarcoma, one synovial sarcoma, one primitive neuroectodermal tumor and one without classification. All cases received interpolatory chemotherapy twice. Before their receiving interpolatory chemotherapy they had no tumor metastases. The maximum diameters of tumors rang from 4 - 15 cm. One patient's tumor disappeared after interpolatory chemotherapy and she received no further therapy. The other 5 cases received operations and one of them received additional pre-operational radiotherapy using Co(60) and pre-operational systemic chemotherapy using ifosfamide and dacarbazine.

RESULTSThe tumors dwindled in size of 1 - 8 cm after interpolatory chemotherapy. All cases saved their crura and had normal functions. After interpolatory chemotherapy, all patients suffered from edema and ache of crura. One patient suffered from lymphatitis. All these patients were followed up for 6 - 20 months. All of them were alive and had pigmentations on their crura. A lung metastasis was found in 1 patient by CT 2 months after surgery, then he was in hospital and treated by chemotherapy.

CONCLUSIONSFor treatment of high-grade soft tissue sarcomas of crura which are difficult to resect in youth, interpolatory chemotherapy is a good choice.
