Plateau refractory wounds are affected by adverse conditions such as hypoxia, strong ultraviolet rays, and frigid, which can cause serious cell function damage, hinder re-epithelialization, and delay or even stop the healing of wounds. Conventional debridement and drainage, functional dressings and other traditional treatments have poor efficacy on this type of wound. Not only do patients have to endure long hospital stays, but they may also suffer from other complications due to long-term non-healing of wounds. In this paper, we report a patient with a plateau refractory wound that had not healed for 2 months. After two applications of platelet lysate gel treatment, the wound healed completely. This treatment method provides a new treatment approach for patients with plateau refractory wounds, which is worthy of clinical reference.

Acral melanoma(AM)is the most common histologic subtype of melanoma in dark-skinned patients and is associated with a worse prognosis and a high mortality rate,largely due to the inconspicuous nature of early-stage lesions,which can lead to late diagnosis.Because of the overlapping clinical and histopathological features of AM with other forms of cutaneous melanomas,early detection of AM requires a multidisciplinary approach that integrates various diagnostic modalities,including clinical examination,dermoscopy,histopathology,molecular testing,radiological imaging,and blood tests.While surgery is the preferred method of treatment for AM,other therapeutic options may be employed based on the stage and underlying etiology of the disease.Immune checkpoint inhibitors,molecular targeted therapy,radiotherapy,chemotherapy,and oncolytic virotherapy represent promising advanced treatment options for AM.In this review,we provide an overview of the latest advancements in diagnostic and therapeutic methods for AM,highlighting the importance of early detection and the prompt,individualized management of this challenging disease.

Objective To investigate the effect of rehabilitation instruction based on resourceful theory on the execution intention of exercise behaviour in patient with the first-episode stroke.Methods From September 2022 to February 2023,a total of 80 inpatients with first-episode stroke from a general hospital in Anhui Province participated in the study.Patients in Wards Ⅰ and Ⅱ were assigned to an intervention group,while those in Wards Ⅲ and Ⅳ were assigned to a control group,with 40 patients per group.The patients in control group received standard interventions,while those in the intervention group were offered with a rehabilitation instruction based on resourceful theory in addition to the standard interventions.Stroke patient rehabilitation exercise behaviour execution intention questionnaire,resourcefulness scale and modified Barthel were employed for assessments before and after the intervention.Results After the intervention,the intervention group showed significantly higher scores inexecutive intention of exercise behaviour,resourcefulness level and daily living activities compared to those in the control group(all P＜0.01).Conclusion Rehabilitation instruction based on the theory of resourcefulness can effectively increase the executive intention of exercise behaviour in the patients with first-episode stroke,improve the resourcefulness thinking levels and enhance the daily living activity of the patients.

Objective:To investigate the changes and clinical significance of vascular endothelial growth factor (VEGF) and vascular cell adhesion molecule-1 (VCAM-1) levels in patients undergoing breast cancer resection before and after radiotherapy.Methods:A total of 110 patients who were treated in our hospital from Jun. 2022 to Jun. 2023 for breast cancer and were to receive radiotherapy after surgery were prospectively selected as the observation group. Another 110 healthy volunteers were selected as the control group. The levels of VEGF and VCAM-1 in peripheral blood were compared, and the relationship among general data, tumor pathology and peripheral blood VEGF and VCAM-1 in the observation group was analyzed, and their relationship with disease and prognosis was analyzed.Results:VEGF and VCAM-1 levels in peripheral blood in the observation group were significantly higher ( F=1288.37, 309.32, P<0.05). The levels of VEGF and VCAM-1 in peripheral blood in the observation group were significantly lower than before radiotherapy ( t=23.45, 11.88, P<0.05). Before and after radiotherapy, VEGF and VCAM-1 levels in peripheral blood in the observation group were correlated with tumor stage, tumor differentiation degree and Ki-67 proliferation index ( ttumor stage=7.05, 2.14, 4.52, 4.76, ttumor differentiation degree=7.12, 6.62, 2.81, 3.15, tKi67 proliferation index=7.25, 4.60, 4.24, 2.48, P<0.05) ; Of 110 patients in the observation group, 73 were effective and 34 were ineffective. VEGF and VCAM-1 in effective group were significantly lower ( t=7.27, 9.08, P<0.05). Spearman correlation coefficient analysis showed that VEGF and VCAM-1 levels were significantly positively correlated with tumor stage and Ki67 proliferation index before and after radiotherapy ( rbefore radiotherapy=0.64, 0.54, 0.52, 0.52, rafter radiotherapy=0.32, 0.39, 0.37, 0.24, P<0.05), and negatively correlated with tumor differentiation degree ( rbefore radiotherapy=-0.41, -0.31, rafter radiotherapy=-0.68, -0.41, P<0.05). The prognostic value of combined radiotherapy was 0.801 [95% CI (0.714-0.871) ], which was higher than that of VEGF and VCAM-1 alone 0.690 [95% CI (0.5955-0.775) ] and 0.734 [95% CI (0.641-0.814) ]. Conclusion:The changes of VEGF and VCAM-1 levels in peripheral blood have a certain value in evaluating the short-term prognosis of patients undergoing breast cancer resection by radiotherapy.

OBJECTIVE: To explore the clinical manifestations and genetic characteristics of patients with congenital central hypothyroidism due to variants of IGSF1 gene. METHODS: Clinical data, results of genetic testing, and follow-up of four patients admitted to Children's Hospital of Soochow University during 2017 to 2021 were retrospectively analyzed. RESULTS: All of the four patients were males. Patient 1 had presented neonatal jaundice, patients 2 and 3 were admitted for growth retardation during childhood, and thyroid function test indicated slightly low free thyroxine (FT4), patient 4 was found to have reduced FT4 in the neonatal period. Genetic testing revealed that all of the four patients have harbored pathogenic variants of the IGSF1 gene, which were all inherited from their mothers. The thyroid functions in all patients were well controlled with oral levothyroxine and regular follow-up. CONCLUSION Pathogenic variants of the IGSF1 gene probably underlay the congenital central hypothyroidism with a variety of clinical manifestations, and genetic testing can facilitate the diagnosis at an early stage.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

Many efforts have been made to understand excitotoxicity and develop neuroprotectants for the therapy of ischemic stroke. The narrow treatment time window is still to be solved. Given that the ischemic core expanded over days, treatment with an extended time window is anticipated. Bestrophin 1 (BEST1) belongs to a bestrophin family of calcium-activated chloride channels. We revealed an increase in neuronal BEST1 expression and function within the peri-infarct from 8 to 48 h after ischemic stroke in mice. Interfering the protein expression or inhibiting the channel function of BEST1 by genetic manipulation displayed neuroprotective effects and improved motor functional deficits. Using electrophysiological recordings, we demonstrated that extrasynaptic glutamate release through BEST1 channel resulted in delayed excitotoxicity. Finally, we confirmed the therapeutic efficacy of pharmacological inhibition of BEST1 during 6-72 h post-ischemia in rodents. This delayed treatment prevented the expansion of infarct volume and the exacerbation of neurological functions. Our study identifies the glutamate-releasing BEST1 channel as a potential therapeutic target against ischemic stroke with a wide time window.

To analyze the clinical features and genetic variants of a child with type 4 familial partial lipodystrophy (FPLD4) and the initial manifestation of diabetes.The male patient with the age of 13 years and 5 months, and the diabetes course was about 3 years, the patient was admitted to Children′s Hospital of Soochow University on November 10, 2021(4 th hospitalization at the hospital), in the course of diabetes, the children repeatedly suffered from diabetes ketoacidosis, and lipid metabolism complications gradually emerged.The gene sequencing showed that the proband and his mother carried dual gene mutations of PLIN1 c. 1325delG(p.G442Afs*99) and SPINK1 c. 194+ 2T>C(p.? ). The PLIN1 gene was the causal gene of FPLD4.The mutations of c. 1325delG in the PLIN1 gene had not been previously reported.Based on the clinical phenotype, family history and genetic testing findings, the patient was diagnosed as FPLD4.In addition, the mutation of SPINK1 c. 194+ 2T>C(p.? ) might increase the risk of chronic pancreatitis.This case report enriched the clinical characteristics and genotype data of FPLD4.Gene sequencing assisted the accurate diagnosis of the type of diabetes.The effects of dual gene mutations on disease progression should be concerned, which were of great significance to develop treatment regimen and disease management.

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes(MELAS) is one of the most common inherited mitochondrial diseases. This paper reports a rare mutation associated with MELAS syndrome, the m. 3252 A>G mutation in the MT-TL1 gene encoding the mitochondrial tRNALeu(UUR). The 6-year-old girl suffered from recurrent convulsion and lactic acidemia. The mtDNA sequencing detected a variant m. 3252A>G(MT-TL1 gene) in the proband and her maternal relatives. The heteroplasmic levels in peripheral blood and urine sediment were 66.53% and 97.42%, respectively, which were obviously higher than those of her maternal relatives. Together with 3 previously reported cases, the variant m. 3252A>G could be classified pathogenic. All the reported pathogenic variants in MT-TL1 gene were reviewed to explore the genotype-phenotype correlations of pathogenic variants in MT-TL1 gene.
