RESUMEN
The cell death mechanisms have a long history of being evaluated in diseases and pathological events. The ability of triggering cell death is considered to be a promising strategy in cancer therapy, but some mechanisms have dual functions in cancer, requiring more elucidation of underlying factors. Colorectal cancer (CRC) is a disease and malignant condition of colon and rectal that causes high mortality and morbidity. The autophagy targeting in CRC is therapeutic importance and this cell death mechanism can interact with apoptosis in inhibiting or increasing apoptosis. Autophagy has interaction with ferroptosis as another cell death pathway in CRC and can accelerate ferroptosis in suppressing growth and invasion. The dysregulation of autophagy affects the drug resistance in CRC and pro-survival autophagy can induce drug resistance. Therefore, inhibition of protective autophagy enhances chemosensitivity in CRC cells. Moreover, autophagy displays interaction with metastasis and EMT as a potent regulator of invasion in CRC cells. The same is true for ferroptosis, but the difference is that function of ferroptosis is determined and it can reduce viability. The lack of ferroptosis can cause development of chemoresistance in CRC cells and this cell death mechanism is regulated by various pathways and mechanisms that autophagy is among them. Therefore, current review paper provides a state-of-art analysis of autophagy, ferroptosis and their crosstalk in CRC. The nanoparticle-mediated regulation of cell death mechanisms in CRC causes changes in progression. The stimulation of ferroptosis and control of autophagy (induction or inhibition) by nanoparticles can impair CRC progression. The engineering part of nanoparticle synthesis to control autophagy and ferroptosis in CRC still requires more attention.

OBJECTIVE: To observe the clinical effect and safety of acupuncture in treatment of neck pain due to cervical spondylosis. METHODS: According to the patients' preference and acceptance for the interventions of neck pain induced by cervical spondylosis, an acupuncture group (221 cases) and a non-acupuncture group (251 cases) were divided. After the control of confounding factors with propensity score matching, 218 cases were included in either acupuncture group or non-acupuncture group. In the acupuncture group, acupuncture was applied to Dazhui (GV 14), Baihui (GV 20), ashi points, bilateral neck-Jiaji (EX-B 2), Fengchi (GB 20), Houxi (SI 3), Shenmai (BL 62), etc. The treatment was given once daily, one course of intervention was composed of 5 treatments and 3 courses were included. In the non-acupuncture group, the oral administration of imrecoxib tablets and cobalt tablets was prescribed for 2 weeks. Before and after treatment, the scores of Northwick Park questionnaire (NPQ) and the simplified McGill pain questionnaire (SF-MPQ) were observed, and the safety was assessed in patients of the two groups. RESULTS: After treatment completion, the scores of NPQ and SF-MPQ were all reduced when compared with those before treatment in each group (P<0.001), and the scores of NPQ and SF-MPQ in the acupuncture group were lower than those of the non-acupuncture group (P<0.001). The incidence of adverse reactions was 6.0% (13/218) in the acupuncture group and was 10.1% (22/218) in the non-acupuncture group, without statistical significance in comparison (P>0.05). CONCLUSION: Acupuncture is effective and safe in the relief of neck pain and the improvement of comprehensive quality of life in the patients with cervical spondylosis.

BACKGROUND: Premature ejaculation is a form of male sexual dysfunction. As people's lifestyle changes and the population ages, the incidence of premature ejaculation continues to increase. Many clinical trials have proven that Chinese medicine has a significant effect in the treatment of premature ejaculation. In this systematic review, we aim to evaluate the effectiveness and safety of Traditional Chinese medicine for premature ejaculation. METHODS: We will search for PubMed, Cochrane Library, AMED, EMbase, WorldSciNet; Nature, Science online and China Journal Full-text Database (CNKI), China Biomedical Literature CD-ROM Database (CBM), and related randomized controlled trials included in the China Resources Database. The time is limited from the construction of the library to April 2019. We will use the criteria provided by Cochrane 5.1.0 for quality assessment and risk assessment of the included studies, and use the Revman 5.3 and Stata13.0 software for meta-analysis of the effectiveness, recurrence rate, and symptom scores of premature ejaculation. ETHICS AND DISSEMINATION: This systematic review will evaluate the efficacy and safety of Traditional Chinese medicine for treating premature ejaculation. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process Trial. TRIAL REGISTRATION NUMBER: PROSPERO CRD42017065316.

To observe the functions of Gualou Xiebai Banxia decoctionï¼GXBDï¼ on regulating lipid metabolism, anti-oxidation, and interposing ox-LDL/Lox-1 pathway, and to explore its anti-atherosclerosis (AS) mechanisms. AS models were established by using 42 Apo-E-/- male mice with high fat diet. AS model mice were randomly divided into the model group, simvastatin group, and GXBD high and low dose groups. C57BL/6J male mice were used as the normal control group, n=10 and the treatment lasted for 8 weeks. The levels of TC, TG, LDL-C, HDL-C, SOD, MDA, GSH-px, and ox-LDL in blood serum were tested 24 h after the last administration. The changes of aortic tissues structure were observed by HE staining; the expression levels of Lox-1 protein and the expression levels of mRNA were detected by Western blot and PCR respectively.Results showed that the blood lipid levels and MDA, ox-LDL levels in blood serum of model group were significantly higher than those in the normal control group, but SOD, GSH-px levels were significantly lower than those in the normal control group, and the Lox-1 protein and mRNA expression levels were also significantly higher than those in the control group(P<0.05), namely aortic atherosclerosis lesions were obvious in model group.The levels of blood lipid and MDA, ox-LDL of GXBD high and low dose groups and simvastatin group were significantly lower than those in model group, while SOD, GSH-px levels were significantly higher than those in model group, and Lox-1 protein and mRNA expression levels were significantly lower than those in model group(P<0.05), namely the aortic atherosclerosis lesions were significantly relieved. The above results indicated that GXBD was capable of modulating blood lipid, anti-oxidation, and inhibiting the expression of Lox-1, and interposing ox-LDL/Lox-1 pathway in the AS model Apo-E-/- mice, which may be one of the mechanisms of anti-atherosclerosis.

OBJECTIVE: To investigate the clinical effects of anterolateral decompression and fixation on thoracolumbar fractures complicated with incomplete paraplegia. METHODS: Thirty-six patients with thoracolumbar fractures complicated with incomplete paraplegia were treated with anterolateral decompression and fixation. RESULTS: The patients were followed up for an average of 18 months, which showed satisfactory recovery of the intervertebral space height and thoracolumbar vertebral curvature. The average Cobb's angle, spinal canal index and Frankel were improved remarkably, and none of the patients developed such complications as break or mobilization of the plate screw. CONCLUSION: Anterolateral decompression and fixation can directly and completely decompress the vertebral canal, promote the functional recovery of the spinal nerves and reconstruct the alignment of the spine as an ideal approach for treatment of thoracolumbar fractures with obvious spinal canal-occupying lesions or severe kyphos complicated with incomplete paraplegia.
