Objective: To study the clinical effect of nursing after laparoscopic myomectomy after nursing intervention. Methods: Retrospective analysis of our hospital from 2009 May to 2012 October in our department, laparoscopic myomectomy in the treatment of 148 cases of uterine fibroids patients clinical data, were randomly divided into 2 groups, 74 cases in each group, the control group routine nursing care to patients, nursing intervention on the patients with study group, The quality of life of patients with depression and anxiety scores were compared between the two groups before and after the rate and nursing of exhaust and ambulation time, hospitalization time, complications. Results: Research group of exhaust, ambulation, time of hospitalization, the incidence of complications compared with the control group, showed significant difference; the study group before operation and nursing of patients with anxiety and depression and quality of life scores compared with the control group, there was no significant difference, nursing intervention, there were significant differences. Conclusion: Laparoscopic myomectomy nursing intervention, can promote the rehabilitation, and improve the living condition, patients with significant effect, should be popularized.

Objective:To investigate the expression of multidrug resistance (MDR1) gene and multidrug resistance-associated pro-tein (MRP) gene in patients with non-small-cell lung cancer (NSCLC) and its relation to histopathological type. Methods:The MDRi and MRP genes were determined by reverse transcription-polymerase chain reaction (RT-PCR) in 48 NSCLCspecimens. Results:The positive rates of the MDR1 and MRP gene expression were 62.5％ and 66.7％ respectively in the48 patients. Twenty-one of the 48 NSCLCs (43.8％) expressed both MDR1 and MRP genes. The positive rates of the MRPgene expression in squamous cell carcinoma was significantly higher than those in adenocarcinoma (P＜0.01), and therewas no significant difference in MDR1 gene expression between the two groups (P＞0.05). Conclusion: The MDR1 andMRP gene expressions were both or respectively in the NSCLCs. The incidence of the MRP gene expression in squamous cellcarcinoma was higher than that in adenocarcinoma.

Objective To observe the clinical effect and safety of subanesthetic doses of ketamine and fentanyl assisted regional anesthesia.Methods 90 children received abdominal operation or limbs operation were selected in our hospital.They were randomly divided into A,B and C group with 30 children in each group.The children in group A received sub-anesthetic doses of ketamine and fentanyl in nerve block anesthesia; the children in group B received sub-anesthetic doses of ketamine and fentanyl anesthesia aided;while the children in group C accepted traditional ketamine anesthesia.The indexes of respiratory frequency,mean arterial pressure,heart rate and oxygen saturation and other basic vital signs as well as anesthesia adverse events of situation were compared.Results The respiratory frequency,mean arterial pressure and heart rate in group A and B were lower than those in group C,the difference was statistically significant(all P ＜0.05),whereas no difference was observed on the oxygen saturation between two groups(P ＞0.05).The respiratory rate,mean arterial pressure and heart rate in group A and B showed no significant difference (all P ＞ 0.05).In adverse reactions,the muscle relaxants was in good condition in group A and B,no obvious body movement and gastrointestinal adverse events observed either.Group C with muscle relaxants in good condition,but body movement and some gastrointestinal adverse reaction can be observed occasionally.Conclusion Subanesthetic doses of ketamine and fentanyl has good anesthetic effect on regional anesthesia,and can effectively reduce the occurrence of adverse reactions,which is worthy of clinical application.

The human Interleukin-2 cDNA containing full-length of encoding region was cloned by RT-PCR from PBMNC and confirmed by DNA sequencing. The hIL-2 recombinant retroviral expressing vector (pLXSN-hIL2) was constructed by inserting hIL-2 cDNA into the BamHI cloning site of pLXSN retroviral vector. After packaged with CRIP packaging cell line, the hIL-2 retrovirions were produced at the titer of 7.6?105CFU/ml. Then a fibroblast cell clone(NIH3T3-hIL2) secreting 118.2U/ml hIL-2 was obtained by infecting the NIH3T3 fibroblast cells with hIL-2 retrovirions. The integration of hIL-2 provirus into the genome of NIH3T3-ML2 cells was confirmed by PCR analysis for NeoR gene. Our data showed that the hIL-2 retroviral vector was successfully constructed, which enables us to further the investigation of the hIL-2 gene therapy in clinical trial.

Objective To compare the differences between laparoscopic-assisted and open resection of rectal carcinoma in respect of peri-operative levels of C-reactive protein (CRP), rest energy expenditure (REE), and visceral proteins. Methods According to patients' choice of operation, either laparoscopic-assisted (n=20, Laparoscopic Group) or open (n=25, Open Group) resection of rectal carcinoma was performed. The levels of CRP and visceral proteins-including albumin (ALB), prealbumin (PRE), transferrin (TRF), and retinal-binding protein (RbP)-were assayed preoperatively and on the 1st, 2nd, and 3rd day postoperatively. The levels of REE were also measured by indirect calorimetry in the morning. Results Compared with the preoperative period, the CRP levels in both groups were significantly increased on the 1st, 2nd, and 3rd day (P0.05). The levels of PRE in the Laparoscopic Group were significantly higher than those in the Open Group on the 2nd postoperative day (P

Objective:To study the influence of the DCs from mononuclear cells in axillary draining lymph nodes of patients with breast cancer to the cytotoxicity of the antigenic specific CTLs stimulated by freeze-thrawing antigen from breast cancer cells in vitro.Methods:The mononuclear cells were isolated from axillary draining lymph nodes,and were cultured with cytokines to induce DCs and tumor draining lymph node cells(TDLNCs) respectively.DCs stimulated by the auto-breast cancer freeze-thrawing antigen(DCs-Ag).TDLNCs were co-cultured with DCs-Ag to derive tumor antigenic specific CTLs(DC-Ag-TDLNC).Then the cytotoxicty of specific CTLs to auto-breast cancer cells and MCF-7 cells was detected.Results:The cytotoxicity of DC-Ag-TDLNC,DC-TDLNC and TDLNC to the auto-breast cancer cells was 67.64%、31.25% and 26.36% respectively,P0.05.Conclusion:Typical DCs can be induced from the mononuclear cells from axillary draining lymph nodes after stimulated with cytokines(rhGM-CSF,rhIL-4 and TNF-?).The DCs possess stronger antigen presentation and can obviously increase the killing activity of tumor antigen specific CTLs to auto-breast cancer cells.

Objective To investigate the concentration changes of vascular endothelial growth factor(VEGF), nitric oxide(NO) and endothelin (ET) in elderly patients with obstructive sleep apnea syndrome (OSAS) combined with eerebrovascular disease.Methods One hundred and thirty-two subjects were divided into four groups: OSAS with cerebrovaseular disease group (OC group), OSAS without cerebrovascular disease group (O group), cerebrovascular disease without OSAS group (C group) and normal control group (N group).The concentrations of VEGF, NO and ET in the plasma were compared in each subgroup.Results The concentration of VEGF was significantly increased in OC group and O group compared with C group and N group[(195.34±56.7)ng/L, (162.34±48.7)ng/L, (156.4 4±51.8) ng/L, (114.1 ± 54.2) ng/L, F= 21.02, P< 0.05].The concentration of NO was increased gradually in OC group, C group, O group and N group[(62.3±4.9)mmol/L,(64.7±5.1) mmol/L, (66.2± 4.2)retool/L, (77.5 ± 6.8) mmol/L, F= 17.35, P<0.05], and the concentration of ET was decreased gradually in OC group, C group, O group and N group[(59.8±9.6)ng/L, (56.5±4.3)ng/L, (54.7±7.9)ng/L, (37.2±8.5)ng/L, F= 4.27, P<0.05].Conclusions The concentrations of VEGF and ET are increased and the concentration of NO is decreased in patients with OSAS.Patients with OSAS combined with cerebrovascular disease have higher VEGF and ET concentrations and lower NO concentration than in patients with simple OSAS.The results indicate that vascular endothelial dysfunction may play an important role in the development of cerebrovascular disease in patients with OSAS.
