Photothermal therapy (PTT) has attracted significant attention due to minimal side effects and high treatment specificity. However, it often requires very high temperature to achieve complete tumor ablation under a single PTT. Such high temperature brings obvious thermal damage and inflammatory response to the body, affecting the therapeutic effect. In recent years, nitric oxide (NO) has been used to significantly inhibit tumor growth and enhance the sensitivity of tumor cells of temperature and drugs, thus enhancing the therapeutic effect. However, compounds as NO donors often have some disadvantages such as poor biocompatibility and untargeted delivery, etc., therefore, this medical application based on NO therapy is limited. In conclusion, the organic combination of NO donors and photothermal agents (PTAs) is expected to overcome the shortcomings of single therapy and achieve the antitumor effect of "1 + 1 > 2". In view of the rapid development of NO combining with PTT in tumor therapy, this review firstly introduces the antitumor mechanisms of different types of NO donors. Then the treatment strategy based on NO combined with PTT is discussed. Finally, the prospects and challenges of this combination therapy strategy in the clinical treatment of cancer are discussed.

OBJECTIVETo investigate the result of hip arthroplasty for failed internal fixation of femoral neck fractures.
METHODSFrom June 2007 to January 2014, 29 cases who underwent hip arthroplasty for failed of internal fixation of femoral neck fractures were reviewed. There were 12 males and 17 females. The mean age was 60.3 years (ranged 43 to 83 years) at the time of the fracture. Left hip was in 16 cases, right hip was in 13 cases. The average interval from fracture to arthroplasty was 23.3 months (ranged, 3 to 48 months).
RESULTSAll of 29 cases were performed total hip arthroplasty. There were 20 cases of cementless cup,7 cases of cementless cup with bone graft, 2 cases of cemented cup with bone graft; 13 cases of cementless stem, 16 cases of cemented stem. There were no complications occurred such as intraoperative fracture of the greater trochanter. The average operative time was (115 ± 38) minutes,the mean intraoperative blood loss was (420 ± 175) ml, the average postoperative drainage volume (240 ± 119) ml, intraoperative blood transfusion was (200 ± 220) ml, intraoperative fluid volume was (2,200 ± 400) ml, the average postoperative blood transfusion was (300 ± 200) ml. There was 1 case get postoperative dislocation. All patients were followed up for 14.7 months in average (ranged, 5 to 24 months). There was no revision for mechanical failure. Harris Hip Score significantly was improved from 51.1 ± 7.5 before the conversion to 88.5 ± 6.4 points at the final follow-up.
CONCLUSIONThe effect of the hip replacement for patients with failed internal fixation of femoral neck fractures was confirmed. This method can shorten the time on the bed and reduce the complications. It benefits the patients earlier functional recovery, but it must control operation indication. The long term efficacy is necessary to further observation.

OBJECTIVETo explore the mechanisms involved in the ligustrazine alleviation of the pulmonary artery hypertension (PAH) in patients of chronic obstructive pulmonary disease (COPD) associated with chronic cor pulmonale (CCP) during exacerbation.
METHODSSeventy patients of COPD and CCP with acute exacerbation were randomly and equally divided into control group and treatment group. The control group received standard treatment with antibiotics, antiasthmatic and expectorant medications, and oxygenation; and the ligustrazine treatment group received ligustrazine treatment (80 mg/d; i.v.; for 2 weeks) in addition to the standard treatment. Before and at the end of 2 week treatment, the clinic responses of the two regimens were evaluated, plasma levels of endothelin-1 (ET-1) and nitric oxide (NO) were determined; arterial oxygen partial pressure (PaO2, mean pulmonary arterial pressure (mPAP), outflow tract of right ventricle (RVOT), and internal diameter of right ventricle (RV) were measured.
RESULTSGood clinic benefits were achieved in both the standard and ligustrazine regimens, plasma level of ET-1, values of mPAP, RV and RVOT decreased significantly, plasma level of NO and PaO2 values decreased (all P < 0.01 vs pre-treatment to all parameters). Compared with the control group, ligustrazine greatly enhanced the clinic efficacy from 77.1% to 97.1% (P < 0.05), and also resulted in more significant changes of all these parameters (P < 0.01 vs control group for all parameters). For both groups, the levels of plasma ET-1 were positively correlated with values of mPAP, RVOT, and RV (r = 0.710, 0.853, and 0.766, respectively, all P = 0.000), and negatively correlated with plasma NO and PaO2 (r = - 0.823, and - 0.752, respectively, all P = 0.000).
CONCLUSIONLigustrazine is effective in treating pulmonary artery hypertension during acute exacerbation of COPD and CCP in patients from the plateau area. The observed changes in the plasma levels of NO and ET-1 in response to ligustrazine treatment suggest that ligustrazine may act through the selective effect on pulmonary blood vessels to enhance the synthesis and release of NO and suppress those of ET-1 from lung vascular endothelial cells, thus reducing pulmonary artery pressure and decreasing pulmonary arterial hypertension.

10.Advancement of insulin effecting signaling pathway of leukemia cell proliferation.
Journal of Experimental Hematology 2012;20(2):514-517
Many reports have documented a role of insulin and insulin-like growth factor 1 (IGF-1) as growth factors in many cancers. The sequence and structure of insulin receptor (IR) and IGF receptor (IGF-1R) are highly similar. Both receptors are overexpressed in leukemia cells.Studies indicate that insulin can enhance the signal of the phosphoinositide 3-kinase/Akt pathways by activating IR or IGF-1R or hybrid IR/IGF-IR receptors, resulting in the proliferation of leukemia cells. High concentration of insulin may inhibit the growth of leukemia cells, the mechanism of which remains to be unclear. Inhibiting IR and IGF-IR can diminish the proliferation of leukemia cells. Therefore, the assumption of IR/IGF-1R as a potential therapeutic target in leukemia appears reasonable. This article summarizes the recent advancement associated with the signaling pathway of insulin effecting the proliferation of leukemia cells.
