Methods Patients (46 cases) with recurrent or refractory and aggressive non-Hodgkin's lymphoma were given mental nursing,preparation and evaluation of the condition of patients before chemotherapy. Complications especially extravasation of infusion fluid should be prevented during chemotherapy and myelosuppression and long-term complications should be prevented after treatment. Results No patient died after treatment but several complications such as infection(14 cases), nausea and vomiting (grade Ⅰ～Ⅱ, 22 cases, grade Ⅲ,2 cases), alopecia (grade Ⅰ～Ⅱ, 27 cases), mucositis (grade Ⅰ～Ⅱ, 4 cases), liver function lesion (grade Ⅱ, 1 case) were found and improved after proper treatment. No nephrotoxicity and hemorrhagic cystitis were found. Conclusions Selective mental nursing,proper chemotherapy preparation,evaluation of patients' condidtion and positively prevention of chemotherapy-related complications could increase the chemotherapy effect of patients with recurrent or refractory and aggressive non-Hodgkin's lymphoma.

Objective To evaluate the effect of postural drainage assisting trachea suction on meconium aspiration syndrome. Methods Total 61 cases of asphyxia neonates with MAS who were born in our hospital from Jan,2007 to Dec,2008, were divided into control group (24 cases) and observing group( 37 cases). The neonates in control group had endotracheal suction directly after intubation. But the infant in observing group was treated with endotracheal suction after postural drainage. The amount of suction from endotracheal tube,the complication of MAS and the outcome of these newborns were evaluated. Results The total amount of meconium drainage from endotrachea in observing group was statistics significantly more than that in control group [( 2. 16 ± 1.82) ml vs ( 1.23 ± 0. 97 ) ml, P ＜ 0. 05 )]; The intubating times in observing group were statistical significantly less than that in control group[( 1.19 ± 0. 46) vs ( 1.79 ± 0. 83 ) times, P ＜0. 01 ). The incidence of complication in observing group was 8. 11% ,which was significantly lower than that in control group(29. 17% ,P ＜0. 05). There were shorter needing oxygen time [(21.30 ± 22. 38) h vs (52. 91 ±39. 20) h,P ＜0. 01]and shorter hospitalization days [(9. 24 ±3.94) d vs ( 14. 39 ±6. 49) d,P ＜0.01 )]in observing group than those in control group respectively. The mortality in control group was 4. 17%, and no death occurred in observing group. Apgar scores of the first minute was similar in both groups ( P ＞ 0. 05 ). But there was significant difference(70. 16% vs 58. 34% ,respectively;P ＜0. 05) in the fifth minute Apgar scoring of 8 ～ 10 scores between the observing group and the control group. Conclusion Postural drainage assisting endotracheal suction may remove meconium in trachea effectively, decrease the complications of MAS and shorten the oxygen days and hospitalization time.

OBJECTIVETo assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer.

METHODSUsing the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data.

RESULTSThe procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day).

CONCLUSIONRLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.
