Receptor-like kinase involves self-incompatibility, male sterility, stress responses, and disease resistance. To better understand the physiological function and biological characteristics of rice receptor-like kinase, we cloned five predicted epitope fragments of rice receptor-like kinase. The purified fusion protein was used as antigen to immunize rabbit to get specific polyclonal antibodies. Western blotting analysis shows that the five receptor-like kinases were expressed in rice leaves.

Objective:To evaluate the efficacy of Qingpeng ointment in the treatment of early herpes zoster neuralgia.Methods:From January to June 2019, sixty patients with herpes zoster (34 males and 26 females, aged 12 to 48 years, onset time of 1 to 7 days) were randomly divided into experimental group and control group. Both groups were given the same antiviral and neurotrophic therapy after admission. The experimental group was treated with Qingpeng ointment for external use in addition. The numerical rating scale (NRS), sleep score (AIS) and adverse reactions of the two groups were evaluated at pre-treatment, 3, 5, 7, 15 and 30 days after treatment.Results:Compared with pre-treatment, the NRS and AIS scores of the experimental group were significantly reduced at each time from day 3, and the difference was statistically significant. The NRS and AIS scores of the control group were reduced at each time from day 7, and the difference was statistically significant. Compared with control group, the NRS scores of the experimental group on the 3rd, 5th, and 7th days and the AIS scores on the 3rd and 5th days after treatment were lower than those of the control group, and the difference was statistically significant. There were no serious adverse reactions in the two groups.Conclusions:External application of Qingpeng ointment can quickly relieve early neuralgia in patients with herpes zoster, improve the patients＇ sleep, and there is no obvious adverse reaction.

Objective:To investigate the role of DDX3 up-regulation in the proliferation of human cervical cancer cells and its correlation with clinical prognosis.Methods:Expression levels of DDX3 in the 59 specimens of cervical cancer and adjacent non-neoplastic tissue collected at Henan Provincial People′s Hospital from April 2012 to March 2013 were detected using immunohistochemistry. A lentivirus-mediated DDX3-over-expression cell line was constructed based on HeLa cells of cervical cancer. CCK-8 assay was used to evaluate cell survival rate. Boyden chamber was used to measure the cell migration and invasion. Real-time fluorescence quantitative PCR was used to detect DDX3 expression level and Western blot was used to detect the expression of EMT and PI3K/Akt signal pathway-related proteins. Results:DDX3 overexpression was associated with FIGO stage, depth of cervical invasion and lymph node metastasis ( P<0.05). Kaplan-Meier analysis revealed that cervical cancer patients with high expression of DDX3 had a poor overall survival ( P<0.05). Compared with the cells transfected with pLVX-Con vector, the expression of DDX3 protein and mRNA was significantly increased in the cells transfected with pLVX-DDX3 (all P<0.01). Cell proliferation was significantly increased following transfection with pLVX-DDX3 for 72 h in HeLa cells compared with that transfected with pLVX-Con ( P<0.05). Compared with the controls, DDX3 overexpression significantly promoted the migration and invasion of HeLa cells ( P<0.05), and increased the expression of N-Cadherin, vimentin and Snail in HeLa cells ( P<0.05). In pLVX-DDX3 group, the expression levels of β-catenin, phosphorylated Akt, and pAkt′s downstream target p-GSK3β were significantly higher than those of pLVX-Con group ( P<0.05). The expression levels of p-Akt, p-GSK3β and β-catenin were decreased when the PI3K/Akt pathway was blocked using the PI3K inhibitor LY294002 ( P<0.05), and the expression levels of N-Cadherin, vimentin and Snail were also significantly decreased ( P<0.05). Conclusions:DDX3 overexpression promotes proliferation, migration and invasion of cervical cancer cells, and induces epithelial-mesenchymal transition (EMT). Its mechanism may be related to activation of the PI3K/Akt signaling pathway.

Objective:To study the clinicopathological, immunophenotypic and molecular genetic characteristics of nodular fasciitis (NF) in unusual sites.Methods:A total of 50 cases of NF diagnosed between January 2015 and January 2021 were reviewed in the Department of Pathology, Henan Provincial People′s Hospital, and the clinical and pathologic data were analyzed. Among them, 14 cases from unusual sites were included in this study. Immunohistochemical (IHC) staining was used to detect the expression of related proteins, and fluorescence in situ hybridization (FISH) was used to detect the breakage of the USP6 gene.Results:There were seven males and seven females in the 14 NF respectively. The lesions were located in the extremities, perineum, breast, wrist joints, the gap between lumbar vertebra 4/5, and in eight cases there was involvement of unusual tissues (six cases in skeletal muscle, one case in nerve root, and one case was intravascular). The tumor boundary was unclear with infiltrating growth. Spindle-shaped myofibroblasts were arranged in bundles or chaotically, with mild pleomorphic, small nucleoli and various mitotic figures. The tumor stroma showed collagenization to myxoid degeneration with erythrocyte extravasation and infiltration of inflammatory cells. IHC staining showed that the spindle cells expressed SMA focally or partially, and p16 diffusely and strongly. FISH showed that 12 of 14 cases had USP6 gene breakage, and two of them occurred in the intrathoracic skeletal muscle with the red signal amplification of USP6 gene.Conclusions:NF in unusual sites shows similar clinicopathological and genetic characteristics to classic NF, but the tumor mostly has infiltrating borders, non-specific and strong expression of p16, and USP6 red signal amplification. The pathological diagnosis of NF in rare sites should be highly vigilant.

Objective:To investigate the clinicopathological features, immunophenotypic and molecular genetic characteristics and differential diagnosis of fibrous hamartoma of infancy (FHI).Methods:Thirty-three cases of surgically removed FHI were collected from the Department of Pathology, Henan Provincial People′s Hospital from October 2011 to December 2020, the clinical and pathologic data with follow-up were collected and analyzed. Next-generation sequencing (NGS) and quantitative real time polymerase chain reaction (q-PCR) were used to study the molecular genetics.Results:The FHI cases occurred in 21 males and 12 females (mean age 16.7 months, range 6 months to 6 years). The sites included trunk ( n=21), limb ( n=11), and neck (n=1). All patients had painless solitary superficial soft tissue masses, the size was 1.5-9.0 cm (mean 3.8 cm). Microscopically, they were composed of mature adipose tissue, fibroblast/myofibroblast bundle and primitive mesenchymal cells in different proportions; giant cell fibroblastoma-like areas were seen in 14 cases. Immunohistochemistry showed variable expression of EGFR in the spindle cells and primitive mesenchymal components. In most cases, the spindle cells were positive for CD34 and SMA; giant cell fibroblastoma-like areas were strongly positive for CD34; and S-100 protein was expressed by adipocytes in all cases. Ki-67 labeling index ranged 1%-5%. There were recurrent somatic EGFR exon 20 insertion/duplication mutations in six cases tested by NGS, and there were three different mutation types: p.Asn771_His773dupAsnProHis, p.Pro772_His773insProProHis, and p.His773_Val774insThrHis. All the above 6 and another 15 tested cases showed EGFR exon 20 insertion/duplication mutations by q-PCR. Conclusions:FHI is a rare benign fibroblast/myofibroblast tumor. The characteristic histologic feature is organoid triphasic morphology, and the molecular feature is somatic mutation of EGFR exon 20 (insertion/duplication).
