Downregulation of LRIG1 was found in many types of cancer. However, data concerning the possible mechanism of LRIG1 reduction in cancers were not reported yet. To analyze the regulation and function of LRIG1 in colorectal cancer (CRC), 6 cell lines, 46 paired tissues from primary CRC cases were employed in this study. In CRC cell lines, under-expression of LRIG1 was correlated with promoter region hypermethylation, and restoration of LRIG1 was induced by 5-Aza-2'-deoxyazacytidine treatment. Subsequently, we ectopically expressed LRIG1 in LRIG1 low-expressing HCT-116 cells and suppressed LRIG1 in LRIG1 high-expressing LoVo cells. We found that over-expression of LRIG1 inhibits cell proliferation and colony formation and tumor growth, while knockdown of LRIG1 promotes cell proliferation and colony formation. Decreased and increased EGFR/AKT signaling pathway may partially explain the lower and higher rates of proliferation in CRC cells transfected with LRIG1 cDNA or shRNA. In clinical samples, we compared the methylation, mRNA and protein expression of LRIG1 in samples of CRC tissues. A significant increase in LRIG1 methylation was identified in CRC specimens compared to adjacent normal tissues and that it was negatively correlated with its mRNA and protein expression. In conclusion, LRIG1 is frequently methylated in human CRC and consequent mRNA and protein downregulation may contribute to tumor growth by activating EGFR/AKT signaling. © 2015 Elsevier Inc.

Aim: To compare the clinical effects of regular versus irregular liver resection for malignant tumors of the liver. Methods: Clinical data for 120 patients who underwent liver resection for malignant tumors of the liver at our hospital from January 2010 to December 2012 were analyzed retrospectively. Results: The amount of bleeding, the incidence of complications and mortality, and the length of hospital stay showed no significant differences (all P > 0.05) between patients undergoing irregular liver resection and those undergoing regular liver resection. The operative time was significantly longer in the regular liver resection group than in the irregular liver resection group (221.8 min ± 101.7 min vs 211.3 min ± 102.6 min, P < 0.05). Conclusion: The aesthetic effect of regular liver resection is better than that of irregular liver resection. For patients with small tumors, irregular liver resection is more simple and effective and can achieve radical results. For those patients with cirrhosis, regular liver resection has higher safety. Liver resection strategy should be selected based on the patient's condition to improve effectiveness and safety. © 2013 Baishideng Publishing Group Co., Limited. All rights reserved.

We sought to evaluate the effect of 125I radioactive seed implantation combined with prosthesis denture on the treatment of oral and maxillofacial malignancy. For this purpose, 10 patients with glandule palatine malignancy were selected and subjected to the treatment plan of radioactive seed implantation during CT examination. All patients were treated as follow. The tumor tissues were extracted first. After 2 weeks, radioactive seeds were implanted in the palatine tissue and the prosthesis denture was made and worn for the tissue defect. Several radioactive seeds were still embedded in the tissue surface of the prosthesis at the same time; 24-36 seeds (average: 28) were used for each patient. All patients were followed up for 3-16 months and the results were evaluated. We found no tumor recurrence or metastasis around the target area in all patients. Significant improvement was shown in terms of speech, mastication, and facial appearance in all cases. Therefore, we concluded that in patients with glandule palatine malignancy, tumorectomy followed by radioactive seed implantation and prosthesis denture are effective for preventing the recurrence and metastasis of malignancy and improving the quality of life. © 2013 Springer Science+Business Media New York.

Aim of the study: The current study aimed to evaluate the clinical efficacy and adverse effects of small doses of propranolol intervention therapy for infants with infantile facial hemangioma in the proliferation stage. Material and methods: A total of 22 patients including 9 males and 13 females with an average age of 5.5 months were enrolled. These patients were diagnosed with facial hemangioma. During the first week of hospitalization, the patients were requested to take propranolol according to their weight (1.0 mg/kg to 1.5 mg/kg once daily). After hospital discharge, the patients were requested to take propranolol consistently and were reassessed every two weeks. We closely observed the process, recorded information about the size, color, and texture of the hemangioma, coped with the adverse effect during the treatment, and evaluated the clinical efficacy of propranolol. Results: The color of the hemangioma faded 24 h after taking propranolol. After 3 months to 9 months of observation, we obtained the following clinical efficacies: level I, 0; level II, 2; level III, 13; and level IV, 7. The effective rate was 100%. The heart rate of 22 patients became slower than before treatment, 2 patients had slight diarrhea that disappeared after treatment, and there was no serious adverse effect during the entire process. Conclusions: With the advantages of minor side effects, convenience, safety, and evident efficacy, the administration of small doses of propranolol is a good method for treating hemangioma in infants.

Primitive neuroectodermal tumor (PNET) is a term used to describe a group of highly malignant neoplasms of soft-tissue origin, with varying degrees of divergent differentiation. The occurrence of peripheral PNET in the head and neck region has been reported infrequently in the medical literature. This disease generally occurs in adolescents and young adults, and rarely occurs in children <3 years old. The current study presents an extremely rare case of pPNET of the parotid gland in a 2-year-old male, which had been previously misdiagnosed and treated as a mumps. The lesion showed the characteristic histological features of pleomorphic cellular infiltrate with hyperchromatic small cells scattered in the fibrovascular stroma, interposed by fibrous septa and Homer-Wright rosettes. Positive immunohistochemical staining for CD99 and vimentin was detected. The patient was treated with chemotherapy and radiotherapy following surgical removal, and has been under close observation since the treatment (approximately seven months), with no signs of recurrence. The clinical history and radiological and histopathological findings are presented, together with the immunoreactivity of this tumor.

OBJECTIVE: To investigate the efficacy of the one-piece ostomy bags for severe organophosphate poisoned patients after catharsis. PATIENTS AND METHODS: Sixty cases of severe organophosphate poisoned patients who were given rhubarb catharsis after thorough nasal lavage were divided into two groups. The observation group used the one-piece ostomy bags whilst the control group used the disposable changing mats. The perineal skin changes, average daily hours of care, and cost of care rates were compared between the two groups. RESULTS: The rates of perineal skin changes were lower in the observation group than the control group (p < 0.05). The average daily hours of nursing and the cost of care were lower in the observation group than in the control group (p < 0.05). CONCLUSIONS: The application of one-piece perineal paste ostomy bag in poisoned patients after the catharsis can prevent the risk of nursing by protecting and promoting the care quality, reducing the nursing workload and improving their work efficiency. It can enhance the nurses' self-esteem, reduce patients' expenses and provide an objective basis for assessing the treatments.

Background Lupus nephritis (LN) is one of the most serious manifestations of systemic lupus erythematosus. Although there have been substantial improvements in LN treatment over the last decade, the outcome remains unoptimistic in a considerable percentage of patients. The aim of this study was to evaluate the efficacy and safety of mizoribine (MZR), a novel selective inhibitor of inosine monophosphate dehydrogenase, as induction treatment for active LN in comparison with mycophenolate mofetil (MMF) and intravenous cyclophosphamide (CYC).Methods Ninety patients with active LN were observed. Thirty patients were given MZR orally at the dose of 300 mg every other day. Thirty patients took MMF at 2 g per day in two divided doses. Thirty patients received CYC intravenously 0.5 g every 2 weeks. Therapeutic effects and adverse events (AEs) were evaluated at the end of 24-week treatment. One-way analysis of variance (ANOVA) followed by Dunn’s test was applied to compare the difference among the groups. For comparing categorical data between two groups, χ2 test was employed.Results Early responses at week 12 were achieved by 73.3%, 90.0%, and 96.7% in MZR, MMF, and CYC groups, respectively. There was no significant difference in the complete remission rates (22.7%, 24.0%, and 25.0%, respectively) or overall response rates (68.2%, 72.0%, and 75.0%, respectively) among the three groups at week 24. The most prominent drop-down of Systemic Lupus Erythematosus Disease Activity Index scores was observed in MMF or CYC group, and the decline of health assessment questionnaire scores in MZR or MMF group was more prominent than that in the CYC group at week 12. Serum complement 3 (C3) or C4 levels were elevated in all groups after the treatments. CYC was more effective in inhibiting anti-double-stranded DNA antibody, while MZR was more effective in inhibiting antinuclear antibody. The incidences of AEs in patients treated with CYC were significantly higher than those in patients treated with MZR or MMF (24.2% for CYC vs. 3.3% for MZR, and 2.6% for MMF, P=0.01).Conclusions MZR is well tolerated and has an effect similar to MMF in the induction therapy of active LN. MZR may serve as an alternative approach for LN patients. © 2014, Chinese Medical Association. All rights reserved.

To investigate the efficacy as well as the complications involved in the use of interstitial Iodine-125 implantation for the treatment of oral cavity and maxillofacial carcinomas.Fifteen patients with oral cavity and maxillofacial carcinomas received treatment planning system (TPS)-guided interstitial Iodine-125 implantation. The apparent activity per particle ranged from 0.6 mCi (2.22MBq) to 0.7 mCi (2.59MBq). The matched peripheral dose delivered by radioactive seeds ranged from 90 to 120 Gy. The efficacy of the treatment and the postoperative complications were evaluated during follow-up.The seeds were implanted successfully in all 15 patients and median number of seeds implanted was 36.53. CT scans were performed in all patients at 1-6 months postoperatively. During follow-up at 6-27 months, seed migration occurred and a good local tumor control was achieved with an overall response of 86.7%. No severe side effects were observed.TPS-guided interstitial Iodine-125 implantation is an effective and safe procedure with minimal invasiveness for the treatment of oral cavity and maxillofacial carcinomas, and it effectively prevents the recurrence of cancer and short-term lymphatic metastasis.
