We describe a 58-years-old man with a primary nasopharyngeal carcinoma accompanying erythroderma. His first symptoms were systemic scattered erythema and itching for six months. Lower right cervical lymphadenectasis was found by physical examination. A neoplasm in nasopharynx could be seen with nasal endoscope. The pathology of the neoplasm was non-keratinizing carcinoma. This case illustrates that "erythroderma" could be a paraneoplastic effect of nasopharyngeal carcinoma.

Objective To observe the effects of acetyl-l-carnitine (ALC) on autophagy, apoptosis and motor function after acute spinal cord injury (ASCI) in rats. Methods Thirty-six adult female Sprague-Dawley rats were randomly divided into sham operation group (Sham group, n=12), simple spinal cord injury group (SCI group, n=12), ALC treatment group (ALC group, n=12). Spinal cord injury model at the level of T10 segment was established using Allen's method. They were assessed with Basso-Beattle-Bresnahan (BBB) scale three days after injury. Then the rats were sacrificed, and the expression of microtubule associated protein 1 light chain 3 (LC3)-II in spinal cord was detect-ed with Western blotting and immunofluorescent labeling, and the number of apoptotic cells were assessed with TUNEL staining. Results The expression of LC3-II and the number of apoptotic cells increased in SCI group compared with those in Sham group (P<0.01), while the BBB score decreased (P<0.001). The expression of LC3-II increased and the number of apoptotic cells decreased in ALC group compared with those in SCI group (P<0.001), while the BBB score increased (P<0.01). Conclusion ALC may promote autophagy, and inhibit apopto-sis to improve the locomotor function after ASCI.

[ ABSTRACT] AIM:In this study, we aim to obtain the induced pluripotent stem cells ( iPSCs) from the patients with sporadic Alzheimer disease ( AD) .METHODS:Three typical Alzheimer’ s patients were chosen, and the epithelial cells were isolated from their urine.We reprogrammed these cells into induced pluripotent stem cells by transfection of 4 factors (Oct4, Sox2, Klf4 and SV40LT) with the technique of electro-transfection.After getting these iPSCs, we continue to differentiate them into neural cells by a specific method—dual inhibition of Smad signaling.RESULTS: The primary cells from 3 AD patients were successfully reprogrammed to iPSCs, and these patients-derived iPSCs were differentiated into neural cells.There was no significant difference, during iPSCs reprogramming and neural differentiation, between cells from AD patients and normal people.CONCLUSION: The urine cells from AD patients were able to transfer to iPSCs, functional neurons and neurogliocytes.

Objective:To investigate the clinical characters and treatments of maxillofacial fractures. Method: A review of 101 maxillofacial fractures was presented with respect to age, sex, cause of fractures, pattern of fractures, treatments and therapeutic effect. Result:The majority of fractures were found in 20-to-50-years-old males. Most fractures happened in summer and the leading causes were traffic accidents. Mandible was the most part of fractures and associated combined injures were found in 31 cases. Rigid internal fixation was the primary treatment. Conclusion:Maxillofacial factures mainly occurred in young adult males and traffic accidents were the main causes. Rigid internal fixation after exact replacement was the primary common treatment.

Objective To observe the ultrastructure and absorption function of colon mucosa in rat with ultra-short bowel syndrome. Methods Totally 30 SD rats were randomly divided into three groups: ultra-short bowel group (90%-95% of the intestine was surgically resected, n = 10), sham group (n = 10), and normal control group (n = 10). All animals were given with enteral nutrition. Scanning electron microscopy was performed 21 days later to observe the morphology of mucosal surface, and transmission electron microscopy was performed to observe the ultrastructural changes of intestinal epithelial cells. The absorption of colon to water, carbohydrates, and amino acid determined after 3 hours of closed perfusion of the colon with D-xylose solution and 15N-glycine on the continuous cycle of colon. Results As shown by the transmission electron microscopy, compared with the normal control group, rats in the ultra-short bowel group showed significantly decreased goblet cells on colonic mucosl surface, increased epithelial cells, longer and denser microvillus, increased area of membrane surface, increased number of cell-cell junctions, increased number of desmosome, tight junction, and gap junctions, higher development of endoplasmic reticulum and dictyosome, and increased number of mitochondria. As shown in the screening electron microscopy, compared with the normal rats, rats in the ultra-short bowl group had significantly deeper colon folds, thicker mucous membrane, increased number of bay openings, and longer and denser microvillus-like structures inside bays. The capability of water absorption was signicatnly higher in the ultra-short bowl group than in the sham group and normal control group (P = 0. 000) . The absorption rates of xylose and 15 N-glycine were also significantly higher in the ultra-short bowl group than in the control group (P ＜ 0. 01). Conclusions The absorption capability can be compensatively increased in rats with ultra-short bowel syndrome. Decreased apoptosis of colon mucosa cells, increased absorption cells, hyperplasia of microvilli, increased area of the membrane surface,and increased number of mitochondria may constitute its material and energy bases.

Objective:To analyze the clinical and physical tactors associated with acute bone marrow suppression in concurrent chemo-radiotherapy for rectal cancer and to provide a reference standard for the best clinical treatment plan. Methods:Retrospective analy-sis was performed on 62 patients with rectal cancer who received concurrent radiotherapy and chemotherapy in our department. The pelvis was contoured for each patient in the radiotherapy treatment planning system and divided into three subsites: lumbosacral spine, ilium, and lower pelvis. Prognostic clinical and physical factors were analyzed by univariate and multivariate analyses. Evaluated prognostic clinical factors included sex, age, clinical stage, original hemoglobin levels, and chemotherapy, operation, and radiation modes;physical factors included V5, V10, V15, V20, V25, V30, V35, V40, V45, V50, Dmax, and Dmean of lumbosacral spine, ilium, low-er pelvis, and pelvis. Results:The percentage of patients who developed acute bone marrow suppression (≥2 grade) was 61.3%(38/62).Univariate analysis of related factors revealed statistically significant differences were sex, chemotherapy, lumbosacral spine V45, il-ium V20, and ilium V30. Multivariate logistic regression analysis indicated that chemotherapy and ilium V30 are the risk factors for acute bone marrow suppression. The receiver operating curve showed that the threshold of ilium V30 was 44%. Conclusion:Acute bone marrow suppression is influenced by more than one factor;local control rate of the tumor and acute bone marrow suppression are tradeoffs in rectal cancer treatment. An appropriate chemotherapy method should be selected, and ilium V30 must be maintained below 44%to prevent bone marrow suppression in rectal cancer patients.

Objective To investigate the clinical efficacy and safety of the cytokine-induced killer cells (CIK) treated in patients with advanced pancreatic cancer. Methods 74 cases (hospitalized from January 2012 to December 2013) with advanced pancreatic cancer (Ⅲ ~ Ⅳ stage) were selected. The patients were randomly divided into two groups: CIK cells treated group (38 patients) and chemotherapy group (36 cases). Patients in CIK cells group received CIK cell infusion therapy , and patients in chemotherapy group received only gemcitabine. The efficacy and safety of all patients were observed. Results The efficacy rate of CIK cells group was 29.0%, with no statistical significance compared to chemotherapy alone group (16.7%). Disease control rate was 63.2%, with statistical significance compared to the chemotherapy group (38.9%). The PFS was 3 months (95%CI:2.5 ~ 3.5), OS 6.8 months (95%CI:6.1 ~ 7.5). 6-month survival rate 41.7%, with statistically significance compared to chemotherapy group. Conclusion CIK cells treated in patients with advanced pancreatic cancer is feasible and safe , and can improve disease control rate , improve immunity and produce clinical benefit in patients.
