Undifferentiated pleomorphic sarcoma (UPS) is commonly found in deep soft tissues, but cutaneous and subcutaneous lesions are relatively rare. The lack of specific symptoms and characteristic manifestations under the microscope makes the diagnosis and treatment of UPS difficult. In April 2022, a patient who was initially diagnosed with cyst infection of the scalp through superficial ultrasound and symptoms was admitted to the Medical Cosmetic Center of the First Affiliated Hospital of Zhengzhou University. After the lesion was resected through surgery, the pathological result showed that the lesion combined UPS. Subsequently, the patient underwent a tumor extended resection, followed by chemotherapy. After 8 months of follow-up, the patient’s prognosis was favorable. This case report aims to provide a reference for the diagnosis and treatment of cutaneous UPS by thoroughly reviewing the diagnostic and therapeutic process of this patient and systematically reviewing related literature.

Background: Colorectal adenoma is the precursor lesion of colorectal cancer, and diabetes mellitus is associated with an increased risk for colorectal cancer. Aims: To investigate the clinicopathological characteristics of colorectal adenoma in patients with type 2 diabetes mellitus (T2DM) and the risk factors for advanced adenoma. Methods: Seven hundred and eighty T2DM patients who underwent initial colonoscopy from January 2018 to December 2020 at the Second Affiliated Hospital of Zhejiang Chinese Medical University were enrolled retrospectively, including 227 patients with colorectal adenoma and 553 patients without colorectal polyps. Furthermore, 227 non-diabetic patients with colorectal adenoma who were 1:1 matched to T2DM-adenoma group for gender, age, body mass index (BMI) and smoking history were collected for a comparison study. The clinical and pathological characteristics of T2DM patients with colorectal adenoma were analyzed, and the risk factors for advanced adenoma were identified by univariate and multivariate analyses. Results: T2DM patients with colorectal adenoma were older than those without colorectal polyps, and male gender, tobacco smoking, and cholelithiasis/cholecystectomy were more frequently seen in T2DM-adenoma group (all P<0.05). The proportions of multiple adenomas and advanced adenoma in T2DM-adenoma group were greater than those in patients without T2DM (16.7% vs. 10.1%, and 21.6% vs. 14.1%, all P<0.05). Multivariate Logistic regression analysis identified that male gender (OR=1.299, 95% CI: 1.041-1.831, P=0.008), age (OR=1.129, 95% CI: 1.001-1.421, P=0.025), BMI (OR=1.118, 95% CI: 1.022-1.715, P=0.038) and T2DM (OR=1.408, 95% CI: 1.141-1.721, P=0.010) were the independent risk factors for advanced adenoma. Conclusions: Multiple colorectal adenomas and advanced adenoma are more likely to be detected in patients with T2DM. Male gender, age, BMI and T2DM are associated with the risk of advanced adenoma.

Objective To evaluate the clinical application of TCM nursing therapies and identify the problems during the therapy implementation, in order to explore the countermeasures to promote its clinical improvement. Methods A descriptive cross-sectional study was conducted,and a self-designed questionnaire was employed to investigate 218 nurses from 148 grade A class three TCM hospitals in China. Results 25 TCM nursing therapies were implemented in these hospitals. Ear acupressure therapy was the most frequently implemented,accounting for 83.5%(182/218);while wax therapy was the least implemented, accounting for 7.8%(17/218). The implementation frequency of these technologies varied significantly, 0~860 times a week. The top three of them were acupoint application therapy, hot compression of Chinese medicine and ear acupoints therapy.TCM nursing therapies were considered to be the most frequently used in insomnia, headache, edema, arthralgia, cold, epigastric pain, hypochondriac pain and fever.Storage of TCM nurses,lacking of TCM knowledge and inapposite therapy implementation were the main problems in the application. Conclusions Scientific and rational allocation of human resources, cultivation of the TCM-specific nursing professional, enhancement of nurses'awareness of Chinese medicine, establishment of a reasonable charging standard, and strengthening the risk management in implementation will promote its clinical development.

BACKGROUND:Cel cryopreservation is required for clinical use of stem cel s, and the current process of cryopreservation however may be harmful to cel viability, pluripotency and differentiation capacity.
OBJECTIVE:To explore the effect of fructose and dithiothreitol on pluripotency and osteogenesis of cryopreserved bone marrow mesenchymal stem cel s.
METHODS:Bone marrow mesenchymal stem cel s were isolated from the bone marrow of Sprague-Dawley rats and pretreated with fructose (200μmol/L), dithiothreitol (500μmol/L) or combined components before cryopreservation. Then the cel s were cryopreseved for 6 months and the morphology of cel s was observed by inverted microscopy. The cel viability was evaluated by MTT, and real-time PCR was used to detect the mRNA expression of Nanog, OCT4 and Sox2. Alkaline phophatase activity assay and alizarin red staining were utilized to detect the osteogenic capacity of bone marrow mesenchymal stem cel s.
RESULTS AND CONCLUSION:Images captured by inverted microscopy showed no significant difference in cel morphology between groups. The MTT results indicated that fructose and combined pretreatment could promote the cel viability of bone marrow mesenchymal stem cel s after cryopreservation, while the real-time PCR results demonstrated that dithiothreitol significantly facilitated the expression of Naogo and Sox2 in bone marrow mesenchymal stem cel s. Moreover, ALP activity assay and alizarin red staining confirmed the positive effects of fructose, dithiothreitol and combined pretreatment on osteogenic capacity of bone marrow mesenchymal stem cel s after cryopreservation, and the best effects were found after pretreatment with dithiothreitol and combined components. Overal , these findings indicate that fructose pretreatment is beneficial for cel viability of cryopreseved bone marrow mesenchymal stem cel s, and dithiothreitol contributes to maintaining the pluripotency and osteogenesis capacity of cryopreseved bone marrow mesenchymal stem cel s.

Objective To assess the relationship between fat metabolic parameters and androgen concentration in the cord blood of newborns of mothers with polycystic ovary syndrome (PCOS). Methods This cross-sectional study included PCOS women (n=55) and neonatal, and 40 cases with matched body mass index (BMI) were used as control. The clinical data including height, body mass, waist circumference, hip circumference of PCOS group, and length and head circumference in newborns after delivery were measured and compared. Blood lipid level, serum insulin and testosterone level were detected using umbilical artery-vein mixed cord blood after delivery. Regression analysis was used to analyze the influence factors of neonatal cholesterol and testosterone levels. Results The neonatal birth weight, head circumference, cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglyceride level were significantly lower, birth height and testosterone level were significantly higher, in PCOS group than those of control group (P＜0.05). Values of waist to hip ratio, BMI, cholesterol, high density lipoprotein cholesterol and testosterone levels were significantly higher in PCOS group than those of control group (P＜0.05). The insulin, cholesterol and triglyceride levels of PCOS mother were risk factors for neonatal cholesterol level(P ＜ 0.05). The cholesterol, triglyceride and free testosterone levels of PCOS mother were risk factors for increased neonatal free testosterone (P ＜ 0.05). Conclusion Mother with PCOS may affect fetal birth weight, head circumference and cord blood lipid metabolism, which may be related with the elevated level of testosterone during the fetal period.

ObjectiveTo investigate the clinic and pathologic features of one patient diagnosed with neurocutaneous melanosis ( NCM ) by biopsy.MethodsA 21-year-old woman presented with a 2-month history of tinnitus,headache,vomiting and 1-month history of impaired vision.At birth,a massive nevus covering most of the posterior abdomen had been noted as well as the presence of multiple smaller lesions all over the body.Magnetic resonance imaging demonstrated a posterior fossa cyst compatible with the Dandy-Walker syndrome and extensive leptomeningeal enhancement. Surgery was performed to cystectomy and to obtain pathologic specimens from the leptomeninges. Biopsy and immunohistochemical study was performed.ResultsAt surgery,diffuse black pigmentation of the leptomeninges and the cyst was found.Under microscope,the cyst and leptomeninges were composed with melanocytes with variable pigmentation.Those cells positive for HMB45,MelanA,S100 and vimentin.Ki-67 positive cells ＜ 1％.The pathologic diagnosis wasleptomeningeal diffusemelanocytosis. Thepatientdied 2months after thesurgery.ConclusionsNCM is characterized by a focal or diffuse proliferation of melanin-producing cells in both the skin and the leptomeninges.NCM could be compatible with the Dandy-Walker syndrome.Definite diagnosis relies upon the histological data obtained by mean of biopsy.

Objective To evaluate the diagnostic value of MR arthrography for rotator cuff tear. Methods A prospective study was undertaken in 32 patients with shoulder diseases using MR arthrography. Abnormalities revealed on MR arthrography of the rotator cuff, the labrum, and the tendon of the long head of the biceps brachii muscle were recorded. The results of MR arthrography were compared with those of arthroscopy and surgery. Results Based on the results of arthroscopy and surgery, 32 patients comprised 14 complete rotator cuff tear, 6 partial rotator cuff tear, and 12 subjects without tear. For detecting rotator cuff tear, the sensitivity, specificity, and accuracy of MR arthrography were 100%, 100%, 100% respectively. For detecting complete rotator cuff tear, the sensitivity, specificity, and accuracy of MR arthrography were 100%, 94%, 97% respectively. Meanwhile, MR arthrography revealed all multi tendon tear and all abnormalities of the labrum and the tendon of the long head of the biceps brachii muscle before arthroscopy. Conclusion MR arthrography is an accurate and comprehensive method for evaluating rotator cuff tear.

Objective To determine the val ue of five MR imaging signs in diagnosing the bucket handle tears (BHT) of menisci of the knee. Methods MR imaging of 139 knees with subsequent arthroscope exams were retrospectively evaluated. Based on the results of arthroscopy, 19 knees had BHT of menisci. Two radiologists evaluated each MR exam independently, with discrepancies resolved by consensus. Each MR exam was analyzed for five signs: a double posterior cruciate ligament sign, a flipped meniscus sign, an absent bow tie sign, an internal displaced fragment sign, and an abnormal circumferential meniscus sign. Sensitivity, specificity, positive and negative predictive values, and accuracy for diagnosing BHT of menisci were calculated for the presence of each individual sign. Results The sensitivities of these five signs ranged between 52.6% and 89.5%, and specificities ranged between 83.3% and 98.3%, respectively. Positive and negative predictive values ranged between 42.9% and 88.2%, and between 92 7% and 98.3%, respectively. The accuracy of these five signs ranged between 82.7% and 96 4%. Conclusion BHT of menisci may have many signs on MR imaging. The diagnostic sensitivities of the internal displaced fragment sign and the abnormal circumferential meniscus sign are the highest. The double posterior cruciate ligament sign has the highest specificity and positive predictive value, while the internal displaced fragment sign has the highest negative predictive value and accuracy.
