[ ABSTRACT] Tyrosine kinase inhibitors ( TKIs) are now advocated as the first-line treatment for chronic myeloid leukemia ( CML) , but facing resistance and relapse .Leukemia stem cells ( LSCs ) are leukemia-initiating cells as the source of resistance and relapse .It is therefore important to discover the molecular biomarker of LSCs for developing anti -LSC strategies in leukemic therapy .15-Lipoxygenase (15-LO) is a key enzyme in the pathway of arachidonic acid and plays an important role in the occurrence and development of CML , which is specifically required for chronic myeloid LSCs . This review summarizes the influence of 15-LO on the chronic myeloid LSC characteristics of marked survival , self-renewal, proliferation , differentiation and apoptosis .

Serum Ca, P, AKP, plasma iPTH, cAMP, urinary Hyp and BMC were measured in 31 cases of Graves' disease. The results showed that about 66.67% of the patients (including 21 controlled and 10 uncontrolled cases) had a decreased BMC, while serum Ca, P, plasma iPTH, cAMP were within the normal range. The data also showed that about 54.6% of the patients had increased serum AKP, but it would not exceed 25 U if no hepatic disease existed. There were positive correlations between serum T, and urinary Hyp, and between urinary Hyp and serum AKP, but a negative correlation between urinary Hyp and BMC. It was suggested that serum AKP and urinary Hyp could be considered as the indices of negative balance of bone metabolism in Graves' disease, and probably it was induced by excessive thyroid hormone directly.

OBJECTIVETo observe the therapeutic effect of Xiehuo Yangyin powder (XHYY) in treating the initial stage of toxic and diffuse goiter (Graves' disease).

METHODSSixty patients were randomly divided into two groups, the treated group (n = 30) was treated with XHYY and methimazole, while the control group (n = 30) was treated with methimazole alone. The TCM syndrome score and thyroxin level in the two groups were compared and analyzed before, and 2 weeks, 12 weeks after treatment.

RESULTSThe syndrome score and thyroxin level in the treated group 2 weeks, 4 weeks, 12 weeks after treatment were reduced in comparing with before treatment, with the improvement better than those in the control group in the corresponding stages (P < 0.05).

CONCLUSIONThe Chinese herbal medicine XHYY plus methimazole, in treating Graves' disease, could rapidly and effectively improve the patients' clinical symptoms and lower the thyroxin level, reduce the daily taken of methimazole.

Objective To explore how medical staff in the oncology department understand management of cancer related fatigue (CRF), and explore what factors influencing the effective practice of CRF management. Methods Qualitative inquiry was adopted. Ten medical staffs in the oncology department were selected for in- depth interview. Generic analysis was applied to code, categorize and interpret the qualitative data. Results Participants believed that many factors influenced the CRF, which hadn′t been assessed as an independent symptom and lacked the systematic, effective and specific interventions. The medical staff, patients and their families neglecting the CRF management was the main barrier. Strengthening system construction and staff training was mentioned as major area which needed to be improved. Conclusions CRF management guideline should be formulated according to our national situations based on the clinical practices, besides, the training of correlated clinical knowledge and skills of medical staff should be strengthened and eventually promote the cancer patients′quality of life.

Objective To construct the nursing undergraduate training model based on TPN, and to apply it in teaching through theoretical teaching, practical teaching, and the second class. Methods The model was constructed on the basis of fundamental theory of undergraduate training in higher education system, with experience from home and abroad, and combined with the actual situation in our college. Results Construction of nursing undergraduate training model of TPN and its application made the students' quality improved, 100% employment rate maintained and fair praises by employers raised steadily. Conclusions TPN training model,consistent with the actual situation in our college, has a good practicality, and provides a proper model for cultivating nursing talents.

Objective To explore the effect of nursing intervention on quality of life and adverse effects of nasopharyngeal carcinoma patients with radiotherapy. Methods A total of 52 patients were randomly divided into two groups. The control group (26patients) received routine nursing, while the experimental group (26 patients) received nursing intervention by nurses. The effect were evaluated from two aspects: the quality of life and the rate of adverse effect. Results The quality of life in the experimental group was higher than that in the control group, while adverse effects were on the contrary. Conclusions Nursing intervention as an effective nursing model can improve the quality of life and decrease adverse effects of patients with nasopharyngeal carcinoma.

OBJECTIVENoninvasive method for estimating the pulmonary vascular resistance (PVR) was used in patients waiting for two staged Fontan procedure to observe the relationship between estimated PVR and surgical results.

METHODSThirty-three candidate patients for two staged Fontan procedures were randomly selected for this trial. Preoperative hemoglobin (HGB), hematocrit (HCT) and pulse oxygen saturation (SpO2) were measured. Estimated PVRs were then calculated by the regression equations. The cases were divided into three groups of low risk group with PVR less than 2.4 wood, high risk group with PVR between 2.4 to 3.2 wood, and extremely high risk group with PVR more than 3.2 wood. The incidences of postoperative low cardiac output and multi-organ failure were compared. Simultaneously, the cases without or with postoperative severe low cardiac output and multi-organ failure after operation were divided into two groups. The preoperative HGB, HCT and estimated PVR among the groups were analyzed.

RESULTSThe rates of postoperative severe low cardiac output and multi-organ failure were 10.0%, 32.4% and 63.6% for the patients of low, high and extremely high risk groups respectively. The difference was significant (P < 0.01). The preoperative HGB, HCT, SpO2 and PVR were all significantly different between the patients without or with postoperative severe low cardiac output and multi-organ failure. The PVR (HGB) were (2.53 +/- 0.56) wood and (3.24 +/- 0.58) wood respectively. The PVR (HCT) were (2.59 +/- 0.58) wood and (3.21 +/- 0.79) wood respectively. The PVR (SpO2) were (2.22 +/- 0.55) wood and (2.93 +/- 0.58) wood, respectively. The differences were all significant (t = 3.25, 2.52 and 3.33 respectively, P < 0.01 or 0.05).

CONCLUSIONSPreoperative estimated PVRs calculated by HGB, HCT and SpO2 were comparable with the postoperative results. Thus, the invasive preoperative estimation of pulmonary vascular resistance could be a method in estimating the surgical indication and predicting the surgical result for two stage Fontan procedure.

OBJECTIVETo provide some possible theoretical and experimental basis for the modern biomedical mechanism of "receiving stimulation, preventing and treating diseases", by exploring the effects of pressure signal's biological transformation of rat "Zusanli" (ST 36) fascia tissue fibroblasts under mechanical stimulation.

METHODSPressure was given on rat "Zusanli" (ST 36) and its adjacent area's fascia tissue cells cultured in vitro and identified by morphology. The contents of prostaglandin E2 (PGE2) and interleukin-6 (IL-6) in culture medium were detected.

RESULTSThe fascia tissue cells in "Zusanli" and its adjacent area are almost consisted of fibroblasts. The pressure stimulation significantly accelerated the synthesis and release of PGE2 and IL-6.

CONCLUSIONAcupoint and non-acupoint fibroblasts can directly receive mechanical stimulation, and then the mechanical signals were transformed as biological ones.
