Objective: To explore the clinical therapeutic method and effect of the thumb-tack needle for subcutaneous embedding therapy on treating insomnia with insufficiency of heart and spleen among breast cancer patients. Methods: Totally 80 breast cancer patients with insomnia with insufficiency of heart and spleen treated in department of oncology, the Second Affiliated Hospital of Xi′an Jiao Tong University from March 2018 till November 2018 were selected and assigned into an experiment group and a control group by random number table, 40 cases in each one. The experiment group applied thumb-tack needle for subcutaneous embedding therapy, selecting Shenmen, Sanyinjiao, Zusanli, Anmian as major acupoint and Taibai as assistant acupoint. The control group used fake needles at the same places. After four-week treatment, we evaluated the therapeutic effect using the Pittsburgh Sleep Quality Index (PSQI) and observed side effects. Results: Before treatment, no significantly statistical differences were observed between the two groups on global and each dimension′s PSQI scores (P>0.05). After treatment, the PSQI scores and PSQI global score of the experiment group on sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, and daytime dysfunction were (1.58±0.53), (1.72±0.33), (1.57±0.64), (1.61±0.68), (1.05±0.42), (1.27±0.53), (8.91±2.73) points respectively, which were (1.86±0.71), (1.90±0.41), (1.85±0.47), (1.97±0.83), (1.42±0.91), (1.56±0.45), (10.86±4.53) points respectively in the control group. There was significant difference between the two groups on PSQI global scores (t=1.998-2.637, P<0.05). The number of patients in the experiment group assessed as clinical cure, obviously effective, effective and noneffective were 8, 13, 9, 10 respectively, which were 1, 5, 12, 22 in the control group respectively. The clinical efficacy showed significant difference between the two groups (χ²=27.68, P<0.01). No side effects, such as infection, needle drop-off and etc. were observed. Conclusions The thumb-tack needle for subcutaneous embedding therapy could improve sleep quality of breast cancer patients with insomnia with insufficiency of heart and spleen, and it′s easy to operate, safe with little side effects.

OBJECTIVETo study the protective effects of Shenqi Fuzheng Injection (SFI) on cerebral ischemia/reperfusion injured aged rats.

METHODSAged SD male rats, weighing 200-300 g, were randomly divided into 4 groups: the model group, the sham-operative group, the nimodipine positive control group (abbreviated as nimodipine group) and the SFI group. Focal cerebral ischemia/reperfusion injured rat model was established by modified Longa method. SFI was administered by intravenous dripping 1 week before ischemia. Nervous function disorder, brain infarction area, serum lactate dehydrogenase (LDH) and creatine kinase (CK) levels, brain contents of Ca2+ , water, MDA and SOD levels were observed 3 hrs after ischemia and 3 hrs after reperfusion.

RESULTSperimental results showed that SFI could obviously improve the deficit of nerve function, decrease water content of brain, reduce the infarction area of brain, and inhibit Ca2 + aggregation. LDH and CK levels in serum and MDA in brain were obviously lower than those in the model group and SOD activity in cerebral tissue was obviously higher than that in the model group.

CONCLUSIONSFI had protective effect on cerebral ischemia/reperfusion injured aged rats, whose mechanism might be related to the inhibition of lipid peroxidation and Ca2+ aggregation.

OBJECTIVETo investigate the effects of ulinastatin (Uti) and low-molecular-weight heparin (Lmwh) on coagulation function and deep vein thrombosis (DVT) in patients undergoing hip joint replacement.

METHODSFrom March to December 2010 150 ASAI-II patients with average age of 72.5 (65 - 85) years undergoing hip joint replacement were randomly divided into 3 groups (n = 50 each): normal saline (NS) control group (Group C), Uti group (Group U) and Lmwh group (Group L). Group U received intravenous infusion of ulinastatin (10 000 U/kg) at preoperative, perioperative and after operation 1, 2 and 3 d, respectively. Group C received the same volume of NS instead of Uti. Group L were injected Lmwh subcutaneously (3200 U/d) at preoperative, after operation 1, 2 and 3 d. Blood samples were taken before operation (T(0)), at the end of surgery (T(1)), 1 d (T(2)), 2 d (T(3)) and 3 d (T(4)) after operation for determination the values of R, K, α angle, MA and CI, using thromboelastography, and the DVT were also examined through color Doppler ultrasonography at 3 d after operation.

RESULTSCompared with T(0), R, K were shorter, α angle, MA and CI were larger in group C, the values at T(2) were up to the peak then declined at T(4). Compared with group C, the value of R, K were larger, the value of α angle, MA and CI were shorter in group U and group L. The DVT checked by ultrasonography were found in 20 cases in group C, 1 case in group U, and zero case in group L. The differences were no statistically significant between group U and group L.

CONCLUSIONIntravenous infusion of Uti during the period of operation can correct the hypercoagulability of blood and decrease the incidence of DVT after operation.

OBJECTIVETo explore the biological function of vascular endothelial cells from hypertrophic scar, and to analyze the relationship between them.

METHODSThe samples from human hypertrophic scar and normal skin tissue were harvested for histological examination. Then vascular endothelial cells were purified and isolated from the samples, and the level of transforming growth factor (TGF) beta1, platelet derived growth factor (PDGF), endothelin1 (ET)-1, fibroblast growth factor (FGF)2 and vascular endothelial growth factor (VEGF) were determined in a single cell with ELISA.

RESULTSFew capillary vessels were observed in normal skin under microscope, while an increased number of them were present in hypertrophic scar, with slender, tortuous in morphology and even occluded. The diameter of blood capillary in hypertrophic scar was tiny under electron microscope, and the exfoliation of endothelial cells was observed. The levels of TGF-beta1, PDGF, ET-1, bFGF and VEGF from vascular endothelial cells from hypertrophic scar were 60 +/- 8, 30 +/- 4, 0.12 +/- 0.03, 52 +/- 5, 18.1 +/- 1.2 microg/cell, respectively, which were obviously lower than those in normal skin (P < 0.05).

CONCLUSIONThe biological function of vascular endothelial cells was attenuated in the hypertrophic scar, which mightbe the result of the production of large amounts of collagen in the scar tissue, as well as hypoxia.

OBJECTIVETo observe the growth and osteogenic property of cultured dog bone marrow stem cells (BMSCs) by investigating the effects of astragalus polysaccharides (APS) on the proliferation and ultrastructure of BMSCs into osteoblasts in vitro.

METHODSBMSCs osteogenic property was detected by improved Wright-Giemsa, Gomori and alizarin dyeing method. The proliferation and differentiation of the induced BMSCs with APS in different concentration and time were detected by MTT assay and the morphologic change of the induced BMSCs was observed by transmission electron microscope (TEM).

RESULTSBMSCs osteogenic property was detected with Wright-Giemsa deep-bluing, Gomori method blacking and with more mineral nodules alizarin dyeing method carmining. APS with concentration of 0.005 mg/mL can promote the proliferation of the induced BMSCs in short-term culture (1th, 3th day) and 50 mg/mL can decrease the effect through long-term culture (5th day). Observed by TEM (5th day), the number of mitochondria, rough endoplasmic reticulum increased and the extracellular matrix was excreted more in the induced BMSCs by APS with concentration of 0.005 mg/mL. However, not only the number of mitochondria, rough endoplasmic reticulum reduced but also the structure was swollen, degenerative, membrance damaged in the induced BMSCs by APS with concentration of 50 mg/mL.

CONCLUSIONAPS with lower concentration in short-term culture may promote BMSCs proliferation and differentiation.

Objective To detect the complications of venous indwelling needle in external jugular vein and veins of upper extremity in patients with breast cancer.Methods One hundred breast cancer in-patients in Department of Oncology of Nanxishan Hospital of Guangxi Zhuang Autonomous Region(September 2006 to August 2008)were screened and divided into external jugular vein group(47 cases)and veins of upper extremity group (53 cases)according to the indwelling site path.During the indwelling period,phlebitis and leakage in two groups were compared.Results It was showed the complication rate of external jugular vein group(6.4%)was conspicuously lower than that in veins of upper extremity group(54.7%,P ＜ 0.01).Conclusions It is suggested that the venous indwelling needle in external jugular vein is in high achievement ratio,the complication rate of phlebitis and leakage is lower,which could rise quality nursing care for breast cancer patient.

Objective: To investigate the efficacy of alternative donor (AD) in the treatment of aplastic anemia (AA) in children. Methods: The clinical data of AA children who received AD HSCT in our center from Apr. 2010 to Dec. 2016 were retrospectively analyzed. The overall survival (OS) rate, implant success rate, incidence of acute and chronic graft-versus-host disease (GVHD) were statistically analyzed. Results: A total of 109 children with acquired AA, including 64 severe AA (SAA) , 32 very severe AA (VSAA) and 13 transfusion dependent non-severe AA (NSAA) , were recruited in this retrospective AD HSCT study, the median age was 6 (0.8-18) years old. Of them, 44 patients with 10/10 matched unrelated donor (MUD) , 44 patients with mismatched unrelated donor (MMUD) and 21 patients with mismatched related donor (MMRD) . All patients did not receive ATG before HSCT and the active infection was excluded. Except 3 patients suffered from a second graft failure (2 of them rescued by second HSCT) , 106/109 (97.2%) were engrafted with neutrophil and platelet recovery occurring at a median of 13 days (range, 9-19) and 16 days (range, 10-81) post-transplant. Until day 100 post transplantation, the incidence was 74.3% (81/109) for acute GVHD (aGVHD) and 39.4% (43/109) for grade Ⅱ-Ⅳ aGVHD, 30.7% (31/101) and 9.9% (10/101) for overall chronic GVHD (cGVHD) and moderate cGVHD, respectively, and nobody developed an extend cGVHD. After median follow up of 39 (0.7-103) months for all patients, 13 of 109 patients died. The estimated 5-year overall survival (OS) of the entire cohort was 88.1% (95%CI 81.1%-91.4%) with no difference among the MUD, MMUD and MMRD cohort (93.2%, 84.1% and 85.7%, respectively, P=0.361) . Conclusion: These excellent outcomes suggest that unmanipulated AD PBSC is a good HSCT source for children with SAA. It's reasonable to consider AD HSCT as first line therapy for SAA children without matched sibling donor. Better strategies are required to prevent GVHD.

Objective: To explore the effects of application of Plato analysis combined with plan-do-check-action (PDCA) cycle in scientific research management of nurses with primary position title. Methods: Twenty-six nurses with primary position title were recruited in this self pre- and post-control study. From January 2012 to December 2013, they were guided by normal scientific research management. In January 2014, the factors which hinder these nurses from writing papers were investigated by the questionnaire titled " the impediments that hinder nurses with primary position title from writing papers" . Based on " twenty-eighty percent laws" of Plato analysis method, the main influencing factors which hinder nurses with primary position title from writing papers were " had no idea" and " did not know how to write although with ideas" . From January 2014 to December 2015, based on the results of the survey and combined with PDCA cycle method, interventions were planned, carried out, analyzed by stage, and then improved continuously. Impediments which hinder writing papers of 26 nurses in January 2014 and December 2015, specific scientific research achievement, total scientific research achievement, and average scientific research achievement of these 26 nurses before intervention (from January 2012 to December 2013) and after intervention (from January 2014 to December 2015) were analyzed. Data were processed with McNemar exact probability test, Wilcoxon signed rank sum test. Results: (1) The cumulative percentages of main impediments " had no idea" and " did not know how to write although with ideas" were decreased from 76.93% in January 2014 to 23.07% in December 2015. The number of nurses who " had no idea" was significantly reduced from 14 in January 2014 to 4 in December 2015 (P<0.01). The total number of nurses who had impediments which hinder writing papers was significantly reduced from 26 in January 2014 to 10 in December 2015 (P<0.01). (2) The total scientific research achievement and average scientific research achievement of the 26 nurses were significantly increased from 5 before intervention to 32 after intervention and 0.19 before intervention to 1.23 after intervention, respectively (Z=-4.838, -3.703, P<0.01). Among which, numbers of specific scientific research achievement of papers published in Journals of Statistic Source, papers published in other journals, science and technology awards, fund projects, national utility model patents, and patents for invention after intervention were all increased than those before intervention (P<0.05 or P<0.01). Conclusions Plato analysis can accurately analyze the main impediments that hinder nurses with primary position title from writing papers. Plato analysis combined with PDCA cycle can improve the overall ability of scientific research of nurses with primary position title and affect the achievements in nursing scientific research, which is worthy of promotion.

OBJECTIVETo investigate the effects of curcumin (Cur) and erythromycin (EM) on multidrug resistance (MDR) reversal of K562/A02 cell line and their mechanism.

METHODSMTT assay was employed to determine the sensitivity of Cur, EM-treated K562/A02 cells to adriamycin (ADM). Flow cytometry was used to measure intracellular mean fluorescence intensity (MFI) of daunorubicin (DNR). P-gp expression was determined by immunohistochemistry. RT-PCR technique was used to examine the mdr1 mRNA level.

RESULTSIC(50) of ADM in K562/A02 cells was decreased when treated with Cur or EM, and the reversal times (RvT) was 4.9, 3.7 respectively. The RvT reached to 11.3 when treated with Cur (2.5 microg/ml) combined with EM (120 microg/ml). The DNR MFI in K562/A02 cells was significantly lower than that in K562 cells (P < 0.01), and was increased significantly when treated with Cur (2.5 microg/ml) or EM (120 microg/ml) (P < 0.05). There was no significant difference between DNR MFI of K562/A02 cells treated with Cur (2.5 microg/ml) or EM (120 microg/ml). Immunohistochemistry showed that P-gp expression was significantly higher in K562/A02 cells than in K562 cells (P < 0.01), and was reduced in K562/A02 cells treated with each (P < 0.01), though being still higher than that in K562 cells (P < 0.01). P-gp expression of K562/A02 cells treated with each drug for 5 days were lower than that for 3 days (P < 0.01), and lowered further when treated with Cur and EM together (P < 0.01). Mdr1 mRNA level in K562/A02 cells was higher than in K562 cells (P < 0.01), and was decreased when treated with each of the drugs (P < 0.01). The mdr1 mRNA level of K562/A02 cells treated with Cur (2.5 microg/ml) plus EM (120 microg/ml) was decreased most significantly than that treated with other group of drugs. After 5 day treatment the mdr1 mRNA level of K562/A02 cells with Cur (2.5 microg/ml) was lower than that with EM 120 microg/ml (P < 0.01).

CONCLUSIONSEither Cur or EM can partly reverse the multidrug resistance of K562/A02 cells and decrease the expression and function of P-gp in a time-dependent way. MDR reversing effect of Cur combined with EM is stronger than that of Cur or EM alone.
