Objective:To investigate the clinicopathological and genetic features of epithelioid and spindle cell rhabdomysarcoma with EWSR1-TFCP2 or FUS-TFCP2 fusion.Methods:The clinical, morphological and immunohistochemical features of 14 cases of epithelioid and spindle cell rhabdomysarcoma with EWSR1-TFCP2 or FUS-TFCP2 fusion diagnosed from January 2019 to December 2022 in the Department of Pathology, Foshan Traditional Chinese Medicine Hospital, Foshan, China were retrospectively analyzed. The cases were all subject to FISH or next generation sequencing for analysis of molecular genetic features. The literature was reviewed.Results:There were 5 males and 9 females, with the age at presentation ranging from 6 to 36 years (mean, 22 years). Tumors occurred in the head and neck (9 cases), pelvic region (2 cases), bladder (one case), right humerus (one case), and the abdominal wall, humerus and pubic at the same time (one case). Presenting symptoms varied by location but often included pain or discomfort. Most of the patients showed aggressive radiographic features with soft tissue extension. The tumors had a median size of 6.6 cm (range, 2-23 cm). The tumors were poorly defined and irregularly shaped. Microscopic examination showed diffuse proliferation of spindle or epithelioid cells. While morphologically high-grade tumors displayed obvious cytological atypia, a high mitotic count and tumor necrosis, low-grade tumors grew in sheets and fascicles composed of spindle, epithelioid cells with moderate or abundant amounts of eosinophilic cytoplasm, without pronounced cytological atypia. The tumor cells expressed Desmin, MyoD1, and Myogenin, as well as ALK, EMA, and CKpan. EWSR1/FUS-TFCP2 gene fusion was detected in 14 cases with next generation sequencing and confirmed by FISH. Six cases had EWSR1-TFCP2 fusions and 8 cases showed FUS-TFCP2 fusions. Follow-up information was available in 13 patients, ranged from 5 to 37 months. At the end of follow-up period, 7 patients died of the disease. Six patients were alive:two cases had local recurrences and metastases, two cases of recurrences, one case of metastasis and one case without recurrences and metastasis.Conclusions:Epithelioid and spindle cell rhabdomysarcomas with EWSR1-TFCP2 or FUS-TFCP2 fusion show a very aggressive clinical course, and more commonly occur in the head and neck. Their genetic hallmark is the presence of EWSR1/FUS-TFCP2 fusions. Familiarity with its clinicopathological characteristics is helpful in avoiding misdiagnoses.

Objective To explore the pathogenic roles of miR-21, estrogen (E2), and estrogen receptor (ER) in adenomyosis. Methods We examined the expression levels of miR-21 in specimens of adenomyotic tissue and benign cervical lesions using qRT-PCR. In primary cultures of cells isolated from the adenomyosis lesions, the effect of ICI82780 (an ER inhibitor) on miR-21 expression levels prior to E2 activation or after E2 deprivation were examined with qRT-PCR. We further assessed the effects of a miR-21 mimic or an inhibitor on proliferation, apoptosis, migration and autophagy of the cells. Results The expression level of miR-21 was significantly higher in adenomyosis tissues than in normal myometrium (P<0.05). In the cells isolated from adenomyosis lesions, miR-21 expression level was significantly higher in E2 activation group than in ER inhibition+E2 activation group and the control group (P<0.05);miR-21 expression level was significantly lower in cells in E2 deprivation+ER inhibition group than in E2 deprivation group and the control group (P<0.05). The adenomyosis cells transfected with miR-21 inhibitor showed inhibited proliferation and migration, expansion of mitochondrial endoplasmic reticulum, increased lysosomes, presence of autophagosomes, and increased cell apoptosis, while transfection of the cells with the miR-21 mimic produced the opposite effects. Conclusion MiR-21 plays an important role in promoting proliferation, migration, and anti-apoptosis in adenomyosis cells by altering the cell ultrastructure, which may contribute to early pathogenesis of the disease. In addition to binding with E2, ER can also regulate miR-21 through other pathways to participate in the pathogenesis of adenomyosis, thus having a stronger regulatory effect on miR-21 than E2.

Objective:To study the clinical and immunological features of two case of rare antisynthetase syndrome (ASS), so as to improve the level of diagnosis and treatment.Methods:Two cases with rare antisynthetase syndrome admitted to the First Affiliated Hospital of Zhengzhou University from July 2020 to August 2022 were collected.Results:The two rare ASS were anti-Zo antibody and anti-Ha antibody positive patients, both of which had interstitial lung disease (ILD) as the main clinical manifestation and positive anti-Ro52 antibody. Two rare antisynthetase autoantibodies manifested cytoplasmic ANA indirect immunofluorescence (IIF) staining pattern, but it is different from the cytoplasmic dense speckled pattern of several common ASS antibodies. After treatment with glucocorticoids and immunosuppressants, case 1 died of respiratory failure due to a long course of disease and late diagnosis, the lung lesions of case 2 improved significantly.Conclusion:When encountering the cytoplasmic ANA fluorescent pattern in ILD patients, especially with anti-Ro52 antibody, it is necessary to screen more myositis specific antibodies to rule out the possibility of rare ASS.

Objective To investigate the effects of long-term exposure to three new types of light emitting diode (LED) sources on the behavior, learning, and memory of rats. Methods A total of 160 specific pathogen-free SD rats were divided into eight groups as followed, trichromatic fluorescent lamps color temperature control group, violet-chip full-spectrum white LED group, blue-chip white LED group, and blue-chip full-spectrum white LED group based on the light sources types, with color temperature of 4 000 K and 6 500 K groups in each group using the 4×2 factorial design. There were 20 rats in each group, with half of the rats were males and half females. Rats were exposed to artificial lighting, and the illumination was set at 750 lx. The rats in each group were exposed to different lighting environments for 12 hours per day for 24 weeks. The open-field and step-down tests were conducted in rats after 24 weeks exposure, followed by sacrifice of rats and measurement of organ coefficients. Differences in body weight, organ coefficients, and neurobehavioral indexes of rats in different groups were compared. Results The spleen coefficient of female rats decreased in blue-chip white LED of 6 500 K color temperature group, and the liver coefficient of male rats decreased in the violet-chip full-spectrum white LED of 4 000 K color temperature, blue-chip full-spectrum white LED of 4 000 K color temperature, and blue-chip full-spectrum white LED of 6 500 K color temperature groups, compared with the same-sex rats in trichromatic fluorescent lamps with same-color temperature control group (all P<0.05). The result of different types of light sources compared in the open-field test showed that the index of total distance and movement speed of female rats in the blue-chip full-spectrum white LED group were lower than those in the other three groups, and the time cost to the central area was longer than that in the blue-chip white LED group and the violet-chip full-spectrum white LED group (all P<0.05). The total distance and movement speed of male rats in the blue-chip full-spectrum white LED group were longer or higher than those in the violet-chip full-spectrum white LED group (all P<0.05). Based on the comparison of color temperature, the time and total distance of male rats in 6 500 K color temperature group were lower than that in the 4 000 K color temperature group (both P<0.05). In the step-down test, both male and female rats in the blue-chip full-spectrum white LED group made more errors compared with other three groups with the same gender (all P<0.05). Conclusion Based on the experimental conditions of this study, the blue-chip full-spectrum white light LED affects behavior, learning and memory of the rats, and trichromatic fluorescent lamp has the lowest effect on neurobehavior. The color temperature also affects behavior of the rats, and high color temperature has higher risk.

Traumatic optic neuropathy(TON) is a direct or indirect optic nerve injury after head trauma leading to vision loss and blindness. As endoscopic techniques spreading, the surgical treatment of TON is mainly accomplished by endoscopic endonasal optic canal decompression. As lack of recognition, some patients elapse the optimistic surgical time. Even after aggressive treatment, however, a full recovery of visual acuity is diminished in TON, which carries substantial burden to both the patients′ family and society. The article reviews the advances in study in the timing of surgery, prognostic factors, and complications in endoscopic surgery for TON to improve the understanding of the disease.

Objective:To investigate the clinical effect of rectangular scar flap combined with autologous thinning split-thickness skin graft for repairing type Ⅳ axillary scar contracture deformity after extensive burns.Methods:From January 2015 to January 2019, patients with type Ⅳ axillary scar contracture deformity after extensive burns were admitted to the Department of Skin Wound Repair Center of Wuhan Third Hospital. Rectangular scar flaps were used to reconstruct the axillary area, Y-shaped incision was made on the short side to release the scar, the resulting defects after flap formation were repaired with autologous split-thickness skin grafts. The hyperplasia and contracture of the grafted skin, the size of rectangular scar flap, the appearance of axilla, the growth of residual axillary hair, and the range of motion of shoulder joint were observed during the follow-up of 18 months to 3 years.Results:A total of 6 cases were selected, including 2 males and 4 females, aged from 18 to 58 years, with the duration of scar contracture deformity ranging from 1 to 23 years. The rectangular scar flaps of all 6 patients survived. At the follow-up of 18 months to 3 years, the axillary scar hyperplasia and the skin graft contracture were mild. At 18 months after operation, the function of shoulder joint was restored with 180° shoulder abduction and lifting. Axillary appearance and residual axillary hair growth were satisfactory, the self-care ability and the quality of life of patients improved.Conclusions:Rectangular scar flap combined with autologous thinning split-thickness skin graft is a good method for repairing type Ⅳ axillary scar contracture in patients with lack of autologous skin sources for extensive burns.
