Objective:To investigate the clinicopathological characteristics of spiradenocarcinoma, cylindrocarcinoma, and spiradenocylindrocarcinoma, and to understand the correlations between their morphological patterns and clinical behaviors.Methods:Seven cases of spiradenocarcinoma, cylindrocarcinoma, and spiradenocylindrocarcinoma diagnosed at Fudan University Shanghai Cancer Center, Shanghai, China from 2015 to 2021 were collected. The clinicopathological characteristics and follow-up data were retrospectively analyzed. Histopathologic evaluation and immunohistochemical studies were carried out.Results:There were four men and three women in the cohort, with ages ranging from 46 to 75 years (mean, 61 years). The tumors were located on the head and neck (four cases), extremities (two cases), and trunk (one case). Histologically, the residuum of a benign neoplasm was present in all cases. One case presented salivary gland-type basal cell adenocarcinoma-like pattern, low-grade (BCAC-LG). Another case showed salivary gland-type basal cell adenocarcinoma-like pattern, high-grade (BCAC-HG). The remaining five cases were invasive adenocarcinoma, not otherwise specified (IAC-NOS). One of IAC-NOS contained a mucinous adenocarcinoma component. Immunohistochemically, BCAC-LG and BCAC-HG predominantly expressed basal cell markers such as p63 and p40, whereas IAC-NOS primarily exhibited positivity for CK7, a glandular epithelial marker. Follow-up was available for six patients, ranging from 1 to 9 years (mean, 4.5 years). Among the four patients of IAC-NOS with follow-up, three showed recurrences, two had regional lymph node metastases, and one died.Conclusions:The malignant components of spiradenocarcinomas, cylindrocarcinomas, and spiradenocylindrocarcinomas in this cohort contain BCAC-LG, BCAC-HG and IAC-NOS. This study also shows the presence of mucinous adenocarcinoma components in IAC-NOS. The tumors with IAC-NOS have a relatively poorer prognosis than those without.

Rosacea is a chronic recurrent inflammatory skin disease, and correct assessment of clinical symptoms and severity may facilitate treatment options.

Rosacea is a chronic inflammatory disease. In addition to subjective evaluation, some objective quantifiable indices are needed for the diagnosis and treatment of rosacea. Some skin imaging and noninvasive measurement tools have been applied to clinical practice, and can provide quantitative or semi-quantitative indices to assist the diagnosis and treatment of rosacea. This review summarizes relevant research progress to provide evidence for clinical standardized application.

Rosacea is a chronic recurrent inflammatory skin disease that mainly occurs on the face. A large number of studies have confirmed that rosacea is related to a variety of systemic diseases, including neuropsychiatric diseases such as anxiety, depression, migraine, Alzheimer′s disease and Parkinson′s disease. This review summarizes research progress in the correlation between rosacea and neuropsychiatric diseases, as well as the underlying mechanisms.

【Objective】 To analyze the clinical and pathological characteristics of mucinous tubular and spindle cell carcinoma （MTSCC） in the kidney so as to evaluate the value of radiotherapy in local treatment of refractory MTSCC. 【Methods】 A case of MTSCC with recurrent recurrence and metastasis was reported， and the existing literature on MTSCC was reviewed and analyzed to explore the value of radiotherapy in the treatment of MTSCC. 【Results】 After three operations， postoperative pathology of the patient showed mucinous tubular and spindle cell carcinoma of the kidney. Radiotherapy was performed in the first recurrence area， and long-term follow-up in the tumor bed area showed no recurrence. 【Conclusion】 MTSCC， a rare renal epithelial tumor， has the low-grade malignance in most cases， and rarely recurs and has metastasis. This patient had repeated recurrence and metastasis before surgery， but after tumor bed radiotherapy after the first recurrence no lesion was found， suggesting that radiotherapy plays a certain role in preventing local recurrence. It is necessary to further explore the value of radiotherapy in the treatment of MTSCC.

Photobiomodulation, also known as photochemical modulation, refers to the use of low-power light from various sources to induce photophysical and photochemical modulation without thermal injury in the body. Photobiomodulation is related to the wavelength and energy of light. Target chromophores for light of different wavelengths include cytochrome C oxidase, opsin, porphyrin, etc., and the parameters such as power density, spot size, and energy density determine the energy of light. At present, many in vivo and in vitro studies have confirmed the application potential of photobiomodulation in the treatment of various skin diseases.

Localized neurovascular dysregulation is an important factor for the occurrence of rosacea, and it has been confirmed that neurogenic inflammation is a key step in neurovascular dysregulation. Intradermal injection of botulinum toxin can relieve facial flushing and burning sensations, which may be attributed to the inhibition of neuropeptide release from nerve endings and degranulation of mast cells. This review summarizes the research progress in neurogenic inflammation in the pathogenesis of rosacea and botulinum toxin in the treatment of rosacea, aiming to provide a basis for nerve-related basic research and clinical treatment of rosacea.

Objective: To investigate the expression and function of the TNF signaling pathway in the early stage of orthodontic tooth movement with periodontitis and to provide evidence to study the early inflammatory response in patients with periodontitis orthodontic treatment. Methods: Sixteen SD rats were randomly divided into four groups: group A--12 h of orthodontic tooth movement of the bilateral maxillary first molars in rats with periodontitis; group B--periodontitis model of the bilateral maxillary first molars without orthodontic tooth movement; group C--12 h of orthodontic tooth movement of the same teeth in rats with healthy periodontium; group D--control group without operations. The bilateral maxillary first molars and surrounding periodontal tissue of each group were collected for gene chip detection. Pathway enrichment analysis, qRT-PCR and GO (gene ontology) analysis were performed to identify differential genes involved in the TNF signaling pathway. Results : Gene chip results showed that the TNF signaling pathway was significantly upregulated in group A, group B and group C (P <0.01). Among the differential genes involved in the pathway, 28 were upregulated and 5 were downregulated in group A, 12 were upregulated and 4 were downregulated in group B, and 12 were upregulated and 1 was downregulated in group C (P <0.05). The most significant GO items included "response to lipopolysaccharide", "inflammatory response", "positive regulation of NF-κB transcription factor activity", "positive regulation of NF-κB import into nucleus" and "response to hypoxia"(P <0.001). qRT-PCR results showed no significant difference in TNF-α mRNA expression in group C compared with that in group D, TNF-α was upregulated in both groups A and B (P <0.01), and mRNA expression decreased in the following order: group A > group B > group C (P <0.05). Compared with group D, the expression levels of prostaglandin-endoperoxide synthase 2 (PTGS2) and interleukin-6 ( IL-6) in groups A, B and C were significantly upregulated (P <0.05), but the expression levels of PTGS2 and IL-6 in group A were lower than those in group B (P < 0.05). Conclusion The TNF signaling pathway is activated in the early stage of orthodontic tooth movement in rats with periodontitis. The pathway products participate in many biological processes and play an important role in the inflammatory response and bone absorption.
