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.

AIM: To explore the immunomodulatory effect of paecilomyces cicadidae polysaccharides (PCPS).METHODS: Subcutaneous injection with 50, l00, 200 mg/kg of PCPS were given in the back of the rats everyday for l5 days. The number of white blood cells (WBC) was counted. The activities of acid phosphatase (ACP) and lactase dehydrogenase (LDH)in liver, kidney, spleen and thymus were detected by automatic biochemistry analyzer. The ability of devouring neutral red and activity of ACP, LDH, arginase in alveolar macrophages were also detected. The body weight of the rat everyday during experiment and weight of the spleen and thymus after the rats were killed were measured and wet weight index was calculated.RESULTS: The wet weight index of spleen and thymus, the activity of ACP, LDH, arginase and ability of devouring neutral red in alveolar macrophages in the test group treated with PCPS were significantly higher than those in control group. CONCLUSION: PCPS shows a significant immunomodulatory effect with the increasing counts of WBC and activation of alveolar macrophages in a dose-dependent manner.

Objective To summarize the experience of double layered anastomosis in thoracoscopic and laparoscopic esophagectomy,and to explore its impact on the postoperative anastomotic complications.Methods Patients with thoracoscopic and laparoscopic esophagectomy from September 2014 to Auguest 2015 were retrospectively included.The cervical anastomosis were conducted by hand-sewn double layered anastomosis on the posterior wall of the gastric remnant,with the anastomotic configuration of end-to-side.The patients' general information and postoperative complications were recorded and analyzed.Results 45 patients with esophageal squamous cell carcinoma were included.The major postoperative complications were gastric dilatation(6/45,13.3％),hoarseness(5/45,11.1％),anastomotic leak/gastric necrosis(2/45,4.4％),anastomotic stricture(0/45,0).All patients were discharged from hospital with no perioperative death.Conclusion Hand-sewn double layered anastomotic technique could be safely used in thoracoscopic and laparoscopic esophagectomy,which could assure the security of the anastomosis.The anastomotic complication rates for this technique are rare enough to be recommended,as compared with other anastomotic methods reported in the literatures.

Objective To investigate the expressions of Sema4D and HER-2 in breast cancers and their relationship with microlymphtic vessel density (MLVD).Methods MLVD and expressions of Sema4D and HER-2 were detected in 110 cases of breast cancer tissues by immunohistochemistry.The relationship of Sema4D and HER-2 expressions with clinicopathologic parameters was analyzed.Results The positive expression rate of Sema4D and HER-2 was 71.82％ (79/110) and 33.64％ (37/110),respectively,with a statistically significant differences compared to those in the control group ( P ＜0.01 ).The positive expression rates of Sema4D and MLVD in cases with lymphatic metastasis were higher than that without lymphatic metastasis ( P ＜ 0.01 ).The expressions of Sema4D and HER-2 were closely correlated with the histological grade,TNM stage,lymph node metastasis,and expression of ER of breast cancers ( P ＜0.05),but were not related to tumor size and expression of PR (P ＞ 0.05 ).On univariate analysis,the disease-free survival rate of patients with Sema4D positive expression was better than those with its negative expression ( P ＜ 0.05).Sema4D expression was positively correlated with the HER-2 expression ( r =0.535,P ＜ 0.01 ).Conclusions Sema4D may play important roles in the carcinogenesis and development of a breast cancer.
