The ATP2C1 gene mutation in one case of familial benign chronic pemphigus was investigated. One patient was diagnosed as familial benign chronic pemphigus by pathology, ultrastructral examination and clinical features. Genomic DNA was extracted from blood samples. Mutation of ATP2C1 gene was detected by polymerase chain reaction (PCR) and DNA sequencing. The results showed that deletion mutation was detected in ATP2C1 gene in this patient, which was 2374delTTTG. No mutation was found in the family members and normal individuals. It was concluded that the 2374delTTTG mutation in ATP2C1 gene was the specific mutation for the clinical phenotype for this patient and was a de novo mutation.

Objective To study the effects of short hairpin RNA (shRNA) targeting STAT3 gene on the proliferation and apoptosis of A375 human malignant melanoma cells.Methods Sense and antisense oligonucleotides with small hairpin structures targeting STAT3 gene were designed,synthesized and cloned into the plasmid vector psiRNA-hHlneo after annealing.Cultured A375 cells were divided into 3 groups: control group receiving no treatment,psiRNA-H1 group transfected with empty plasmid,and psiRNA-H1/STAT3 group transfected with the recombinant plasmid containing the shRNA.After additional culture for different durations,reverse transcription PCR and Western blot were performed to detect the expression of STAT3 mRNA and protein,methyl thiazolyl tetrazolium (MTT) assay to evaluate cell proliferation,flow cytometry to assess cell cycle and apoptosis.Results The expression level of STAT3 mRNA and protein in A375 cells in psiRNA-H1/STAT3 group (0.2136 ± 0.0626,0.8214 ± 0.043,respectively) were significantly lower than that in the control group (0.7826 ± 0.0701,3.1693 ± 0.0846,respectively,both P ＜ 0.01) and psiRNA-H1 group (0.8518 ± 0.0783,3.218 ± 0.078,respectively,both P ＜ 0.01 ).The inhibition rates of cell proliferation at 24,48 and 72 hours were 21.35％ ± 2.12％,32.52％ ± 2.64％ and 40.4％ ± 3.08％ respectively in psiRNA-H1/STAT3 group,statistically different from those in the control group (1.39％ ± 0.53％,3.05％ ± 1.16％,4.41％± 1.42％,respectively,all P ＜ 0.01) and psiRNA-H1 group (2.63％ ± 1.38％,5.84％ ± 2.47％,10.32％ ±2.48％,respectively,all P ＜ 0.01).Flow cytometry showed a statistical increase in cell apoptosis rate in psiRNA-H1/STAT3 group compared with the control and psiRNA-H1 group (81.06％ ± 2.10％ vs.26.28％ ±0.47％ and 27.31％ ± 1.05％,both P ＜ 0.01 ).The psiRNA-H1/STAT3 group exhibited a higher percentage of cells at G0/G1 phase (68.43％ ± 4.00％) but a lower percentage of cells at S phase (17.4％ ± 2.05％) compared with the control group (60.07％ ± 2.47％,P ＜ 0.05; 28.40％ ± 2.09％,P ＜ 0.01 ) and psiRNA-H1 group (60.29％ ± 2.26％,27.34％ ± 3.63％,both P ＜ 0.05 ).Conclusions The small interference RNA targeting STAT3 gene can specifically down-regulate the expressions of STAT3 mRNA and proteins in,inhibit cellular proliferation of,and induce apoptosis in,A375 cells.

To investigate the role of progesterone receptor (PR) expression in malignant melanoma (MM), PR and proliferative cell nuclear antigen (PCNA) expression were immunohistochemistrically evaluated in a series of 35 specimens of MM, and the correlation between the immunohistochemistrical findings and clinicopathological data was also analyzed. PR expression was detected in 25.7% (9/35) of the patients with MM. No PR expression was observed in nevi. PR expression was inversely correlated with PCNA expression (r=-0.353, P=0.026). PR expression was slightly increased in females, subjects aged under 55 y, those with ulceration, non-acral subtype and diagnosis delay longer than 1 y, but the difference was not statistically significant. Selective expression of progesterone receptor in malignant melanoma might be correlated with inhibited tumor growth.

Objective To investigate the malnutrition status among the elderly in age care institutions in Shanghai suburb and analyze its potential influential factors.Methods The MiniNutritional Assessment (MNA) was adopted to evaluate the nutritional status of the 190 elderly people in age care institutions.The dietary supply by the institution canteen and the quantity of residual food left by the malnourished elderly people were weighted.Results In the age care institutions,the malnutrition rate reached 23.7％,47.9％ of the elderly people were at the risk of malnutrition,and only 28.4％ of the elderly people were well nourished.Logistic regression analysis showed that the major influential factors for malnutrition in the elderly people were food intake ability,mobile capability,chewing and swallowing ability,ageing and mental Illness.The malnourished elderly people had the most residual meat and vegetables,and insufficiency of nutrient intake was the main cause for the malnutrition in the elderly people.Conclusions The elderly people in age care institutions in Shanghai suburb have the higher risk of malnutrition.The malnutrition occurs under influence of many factors,of which some are unavoidable,however,some factors like dietary factors can be changed to improve the nutritional status of the elderly people in age care institutions.

Objective:To explore the clinical effect of simultaneous whole-course hyperfractionated intensity-modulated radiation therapy combined with chemotherapy and nimotuzumab in the treatment of advanced nasopharyngeal carcinoma.Methods:A total of 64 patients with advanced nasopharyngeal carcinoma who were admitted to Kaiping Central Hospital of Guangdong Province from June 2017 to January 2019 were selected and divided into the observation group and control group according to the random number table method, with 32 cases in each group. Both groups were given chemotherapy and nimotuzumab on the basis of radiotherapy. The observation group received simultaneous whole-course hyperfractionated intensity-modulated radiation therapy, and the control group received conventional fractionated intensity-modulated radiation therapy. The short-term efficacy, Karnofsky score, overall survival rate, progression-free survival rate, acute radiation reaction, and late radiation injury in the two groups were observed.Results:Six months after radiotherapy, the efficient rate of the observation group was higher than that of the control group [96.9% (31/32) vs. 75.0% (24/32), χ2 = 6.335, P < 0.05]. At the end of radiotherapy and 3 months after the end of radiotherapy, the Karnofsky scores of the observation group were higher than those of the control group, and the differences were statistically significant [(75±3) points vs. (71±3) points, t = 5.891, P < 0.05; (80±4) points vs.(77±4) points, t = 3.201, P = 0.002]. All patients were well tolerated, no grade 4 acute radiation reaction was observed, and radiotherapy was completed as planned. The incidence rate of oral mucosal reaction in the observation group was lower than that in the control group [21.9% (7/32) vs. 50.0% (16/32), χ2 = 5.497, P < 0.05]. The incidence rates of severe dry mouth and neck soft tissue fibrosis in the observation group were lower than those in the control group [6.2% (2/32) vs. 28.1% (9/32), χ2 = 5.379, P = 0.043; 3.1% (1/32) vs. 21.9% (7/32), χ2 = 5.143, P < 0.05]. The follow-up time was 14-20 months, and the median follow-up time was 17 months. There was no statistical difference in overall survival time between the two groups ( χ2 = 0.553, P = 0.557). The progression-free survival time of the observation group was better than that of the control group ( χ2 = 3.954, P = 0.044). Conclusion:The simultaneous whole-course hyperfractionated intensity-modulated radiation therapy combined with chemotherapy and nimotuzumab are effective in the treatment of advanced nasopharyngeal carcinoma, and the adverse reactions can be tolerated.
