Aims: To explore the associations between two endoplasmic reticulum (ER) stress proteins, protein disulfide isomerase (PDI), binding immunoglobulin protein (BIP), and the development and progression of pressure ulcers (PUs) in spinal cord injury (SCI) paraplegia patients. Methods: ELISA kits were used to measure the levels of serum PDI and BIP in 67 SCI paraplegia patients with PUs and 61 SCI paraplegia patients without PUs. The associations between PDI and BIP, PU formation, PU staging, and pressure ulcer scale for healing (PUSH) score were analyzed. Results: The patients in the PU group had higher levels of PDI and BIP than those in the non-PU group (both p < 0.05). Furthermore, the levels of PDI were positively correlated with those of BIP (r = 0.707, p < 0.0001). There were significant differences in the PDI and BIP levels among the different stages of PU (all p < 0.05). As the PU stages progressed, the levels of PDI and BIP first increased, then decreased, and finally peaked at stage III of the PUs. The PUSH scores significantly declined 7 days after debridement for the PU stage II (p < 0.01) but showed no significant difference between stages III and IV at 7 days after debridement (p > 0.05). The PUSH scores also decreased at 28 days after debridement for stages II, III, and IV (all p < 0.01). Higher PUSH scores indicated a longer time of debridement accompanied by a longer wound surface healing time (p < 0.05). Conclusion: ER stress proteins may be involved in the process of PU formation and healing; moreover, the levels of PDI and BIP were also associated with the severity of the PUs. Finally, we found that the PUSH scores can be used as a reference to evaluate PU severity and healing. © Copyright 2016, Mary Ann Liebert, Inc. Source

Objective: This study aims to investigate spontaneous cell apoptosis in the prediction of the radio-sensitivity of nasopharyngeal carcinoma (NPC) cells and the molecular foundation of differential spontaneous apoptosis rate. Methods: The surviving fractions and radiation biological parameters of well and poorly differentiated NPC cell lines (CNE-1/CNE-2) were determined through colony-forming assay and radiation dose-survival curve using a single-hit multi-target model and a linear quadratic model. Early- and late-stage apoptotic events were detected by flow cytometry on days 2, 4, 6, and 8. The mRNA and protein expression levels of apoptosis-correlated genes (Bcl-2, Bcl-xl, Bcl-w, Bax, Bad, Bid, and Bak) were detected using RT-PCR and western blot. Results: CNE-2 was more radio-sensitive than CNE-1, and CNE-2 exhibited higher rates of early- and late-stage apoptotic events than CNE-1 on the same culture days (P<0.05). The mRNA and protein expression levels of Bcl-2, Bcl-xl, Bcl-w, Bax, Bad, Bid, and Bak were significantly higher in CNE-2 than in CNE-1(P<0.05). Conclusion: The radio-sensitivity of NPC cells can be detected based on their spontaneous apoptosis rate, which is related to the different expression levels of apoptosis-correlated genes. Source

Nowadays, advanced non-small cell lung cancer is still an incurable disease. Recent researches have led to considerable progress in the treatment of non-small cell lung cancer. This article reviews the main studies on chemotherapy on non-small cell lung cancer and discusses the new therapeutic strategies available to date. Stable disease (SD) is necessary in chemotherapy for tumor. The proportion of population with responders or SD basically maintained similar regardless of regimens. The overall survival after chemotherapy for patients with SD was lower than patients with responders, and higher than patients with progressive disease. Greater benefits could be achieved in patients with effective induction chemotherapy using chemotherapeutic agents for maintenance therapy, whereas the benefits were relatively small for patients with SD. It has been found that epidermal growth factor receptor (EGFR) mutation status had certain correlation with the efficacy of chemotherapy. First-line chemotherapy has shown advantages in effective rate and progression free survival on EGFR mutant. EGFR mutation produced significant effects on the efficacy of postoperative adjuvant chemotherapy. Patients with EGFR mutation had a higher effective rate than wild-type EGFR patients, and patients with responders had a greater benefit in progression free survival from maintenance therapy. However, it is still necessary to carry out more careful and deeper studies and analyses on traditional cytotoxic chemotherapy, to further optimize cytotoxic chemotherapy and to use molecular targeted agents with different mechanisms. © 2014, Int J Clin Exp Med.

Background: The abnormality of some parameters such as congruence angle has statistical significance on anterior knee pain has been confirmed under CT measurement, but has not been confirmed through clinical operations. Objective: To analyzes the relationship between the parameter of knee joint and anterior knee pain through measuring the parameters such as congruence angle, patellofemoral index, lateral patellofemoral angle and tilt angle. Methods: Fifty patients with anterior knee pain caused by varying degrees of atellofemoral cartilage damage were included, and the parameters such as congruence angle, patellofemoral index, lateral patellofemoral angle and tilt angle were measured on the patellar X-ray axial film. The parameters were compared with those of the other 50 patients without anterior knee pain and only with meniscus injury. Results and Conclusion: There were significant differences in congruence angle, patellofemoral index and tilt angle on the patellar X-ray axial film, and there was no significant difference in lateral patellofemoral angle. The congruence angle and patellofemoral index have important diagnosis value for the patients with anterior knee pain caused by patellofemoral joint disorders and are considered as the most effective parameters which has clinical efficacy for the patients with patellofemoral joint disorders.

Kanglaite injection is a new, broad-spectrum, antitumor diphase emulsion, which can be intravenously administered. In recent years, studies have demonstrated that the antitumor activities of Kanglaite include the redistribution of tumor cell cycle, apoptosis induction in tumor cells, tumor angiogenesis and tumor growth inhibition, and COX-2 expression downregulation. In addition, the treatment can prolong the repair time of radiation injuries. Moreover, Kanglaite injection improved the patients' immunity and their quality of life when combined with radiotherapy for the treatment of lung cancer, nasopharyngeal cancer, esophageal cancer, and metastatic tumors.
