Jasmonic acid (JA) is a common plant hormone with regulatory effects on plant growth and development. The jasmonate ZIM-domain (JAZ) proteins (JAZs), as key regulators in the JA signaling pathway, are involved in multiple biological processes such as anthocyanin accumulation, flowering time modulation, and secondary metabolite synthesis in plants. JAZs are essential components of many regulatory signaling networks. The JAZ genes, members of the plant-specific TIFY family, have been identified in the genomes of a variety of horticultural plants. Here, we summarized the research progress in the roles of JAZs in horticultural plants, aiming to give insights into the further study of the biological functions and regulatory networks of JAZ genes in plants.

Flowering and bolting are important agronomic traits in cruciferous crops such as Brassica juncea. Timely flowering can ensure the crop organ yield and quality, as well as seed propagation. The WRKY family plays an important role in regulating plant bolting and flowering, while the function and mechanism of WRKY12 in B. juncea remain unknown. To explore its function and mechanism in bolting and flowering of B. juncea, we cloned and characterized the BjuWRKY12 gene in B. juncea and found that its expression levels were significantly higher in flowers and inflorescences than in leaves. BjuWRKY12 belonged to the Ⅱc subfamily of the WRKY family, and subcellular localization indicated that the protein was located in the nucleus. Ectopic overexpression of BjuWRKY12 in transgenic lines promoted bolting and flowering, leading to significant increases in the expression levels of flowering integrators SOC1 and FUL. Furthermore, yeast one-hybrid and dual luciferase reporter system assays confirmed that BjuWRKY12 directly bound to the promoters of BjuSOC1 and BjuFUL, undergoing protein-DNA interactions. This discovery gives new insights into the regulation network and molecular mechanisms of BjuWRKY12, laying a theoretical foundation for the breeding of high-yield and high-quality varieties of B. juncea.

Osteoporotic vertebral compression fractures(OVCFs)are common orthopedic conditions that can lead to spinal pain and deformity,which greatly affects the quality of life of patients.Currently,there are various treatment methods for OVCFs,but there is still a lack of standards for optimal treatment modalities.Therefore,this article introduces the current treatment methods and character-istics of epidemiology for OVCFs,in order to improve the awareness of this disease among clinicians and provide a reference for select-ing more appropriate treatment regimens.Conservative treatment measures,such as bracing and analgesia,are the basic treatment mea-sures for OVCFs,and anti-osteoporosis drugs play a crucial role in management.Minimally invasive procedures,including percutane-ous vertebroplasty and percutaneous balloon kyphoplasty,remain the primary surgical interventions,and traditional open surgeries are also an important part of treatment,such as anterior spinal fusion,combined anterior and posterior spinal fusion,posterior spinal fusion with three-column osteotomy,and posterior spinal fusion with vertebroplasty.Furthermore,surgeons should focus on the accumulation of related surgical techniques and skills during surgery to effectively address the challenges and complications associated with surgical interventions.Finally,scientific and appropriate treatment methods should be selected for patients,in order to improve long-term treat-ment outcomes and increase the degree of satisfaction among pa-tients.

Objective:To summarize and analyze the clinical characteristics of patients with sudden sensorineural hearing loss(SSHL) accompanying diabetes mellitus, to explore whether diabetes affects the treatment outcomes during hospitalization, and to identify the factors influencing the efficacy of SSHL patients with diabetes. Methods:A retrospective analysis was conducted on clinical data from 939 patients with SSHL. The baseline characteristics, and onset conditions of the diabetes group(79 cases) and the non-diabetes group(860 cases) were compared. Propensity score matching(PSM) was applied in a 1︰ 2 ratio to match initial hearing levels with baseline characteristics such as age, sex, and BMI, resulting in 73 diabetes cases and 144 non-diabetes cases for treatment efficacy comparison. For the analysis of prognostic factors, a logistic regression model was established based on the treatment outcomes of 217 patients with SSHL. Results:The proportion of SSHL patients accompanying diabetes was 8.40%(79/939). Compared to non-diabetic patients, those with diabetes were older(median age of 53 years in the diabetes group and 39 years in the non-diabetes group) and had a higher proportion of hypertension(43.04% vs 12.67%), with significant difference observed(P<0.05). After PSM, the treatment efficacy during hospitalization was better in the diabetes group than in the non-diabetes group(58.90% vs 47.92%), although the difference was not statistically significant(P>0.05). The prognosis of patients with SSNHL accompanied by diabetes was analyzed using a multivariate logistic regression model that included age, HDL-C, and INR as variables; however, no statistically significant differences were found(P>0.05). Conclusion:Patients with SSHL accompanying diabetes are generally older with a higher incidence of hypertension. The presence of diabetes does not affect the treatment outcomes during hospitalization.

Objective:To explore the clinical characteristics, audiological outcomes, and factors influencing the efficacy of pharmacological treatment in patients with sudden hearing loss associated with large vestibular aqueduct syndrome(LVAS). Methods:A retrospective analysis was conducted on the clinical data of 77 bilateral LVAS patients(117 ears) hospitalized for sudden hearing loss from January 1, 2009, to December 31, 2023. The inclusion criteria required that patients to be diagnosed according to the Valvassori standard and had received standardized pharmacological treatment. Clinical features, audiological outcomes, and treatment efficacy were analyzed. Statistical methods were employed to identify factors associated with treatment outcomes. Results:The age of the enrolled patients ranged from 4 to 37 years. The age of onset for the initial hearing fluctuation varied between 0 and 24 years, with a mean age of 5.8 years. The male-to-female ratio was approximately balanced(37 males and 40 females). The proportion of unilateral to bilateral sudden hearing loss was 1.0︰1.2, with unilateral right ear hearing loss being more frequently occurring(64.9%). Triggering Factors: Triggers included no identifiable factors in 48.1% of cases, a history of head trauma(24.7%), upper respiratory tract infections(11.7%), onset following physical fatigue(11.7%), and less frequently, noise exposure, alcohol consumption, or emotional stress(each 1.3%). Clinical Symptoms: Hearing loss was the sole symptom in 35.1% of cases. Concurrent symptoms included vertigo in 44.2% and tinnitus in 46.8%. Patients with a disease duration of ≤14 days demonstrated a treatment efficacy rate of 75.0%. Among those who responded to treatment, 93.0% had profound or greater hearing loss prior to therapy, with an average improvement in hearing thresholds of 32 dB HL. In pretreatment, 68.9% of patients exhibited low-frequency air-bone gaps, increasing to 76.1% post-treatment. Additionally, 17.6% of treated ears demonstrated a ≥15 dB HL improvement in low-frequency bone conduction thresholds. In the non-responsive group, 7.3% of ears still showed some improvement in bone conduction thresholds. Statistically significant differences(P<0.05) were observed between the treatment-effective and non-effective groups concerning the age of initial hearing fluctuation, disease duration, and severity of hearing loss at onset. Conclusion:The efficacy of pharmacological treatment for sudden hearing loss in LVAS patients is influenced by the age at onset, duration of the disease, and severity of hearing impairment. Early diagnosis and timely intervention significantly enhance treatment efficacy, particularly in patients with a disease duration of ≤14 days and an initial sudden hearing loss. Patients with severe hearing loss, especially those with profound or greater impairment, exhibit greater sensitivity to treatment. Pharmacological interventions positively impact both air conduction and bone conduction thresholds, with the observed improvement in bone conduction thresholds warranting further investigation.

Objective:To explore the clinical efficacy of staged reconstruction with anterolateral thigh flap (ALTF) for wrist-forearm soft tissue defects of electrical burns.Methods:A retrospective observational study was conducted on 10 patients who had wrist-forearm soft tissue defects after electrical burns and were admitted in the Department of Burns, Zhengzhou First People's Hospital from January 2019 to December 2022. The patients were 6 males and 4 females, aged 8 to 64 years. All the patients were third-and-fourth degree electrical burns. Debridement was performed to remove the necrotic tissues around the wound in stage I surgery. Area of the wound after debridement ranged from 15 cm×11 cm to 31 cm×20 cm. According to the condition of wrist-forearm injury, the wounds with relatively mild injury were retained. Free ALTF was used to cover the wound surface. Size of the flaps ranged from 16 cm×12 cm to 32 cm×21 cm. The descending branch of lateral circumflex femoral artery and the accompanying veins carried by the flap were anastomosed end-to-end with the radial artery and vein or ulnar artery and vein in the recipient site, respectively. Conditions of other vessels were explored. The great saphenous veins in a length of 10-18 cm was used to bridge the occluded arteries. The donor sites were covered by medium thick skin grafts from trunk. After survival of the flap, stage Ⅱ surgery was carried out to debride the wound temporarily retained in stage I surgery and to thin the flap, then had all the wound covered with the thinned flap. Follow-ups were conducted at outpatient clinic, and via telephone and WeChat interviews. The limb salvage, flap survival, vascular compromise and other complications, as well as the donor site healing were observed. The wound coverage rate of the thinned flap. The appearance of flap, donor site scar hyperplasia, the patient satisfaction with the shape and function of the donor site at 6 months after the stage Ⅱ surgery were evaluated. Likert scale was employed to evaluate the patient satisfaction. The Michigan Hand Outcomes Questionnaire (MHQ) and Disabilities of the Arm, Shoulder and Hand (DASH) were used to evaluate the upper limb function in daily life of the patients.Results:The limb salvages in the 10 patients were all successful, and the flaps survived without any postoperative event of vascular compromise or other complication. One patient had mild cyanosis at the edges of flap after surgery and regressed at 7 days later. One flap had poor blood circulation and partial necrosis. The thinned flaps covered the wound completely after the stage-Ⅱ flap thinning surgery. The postoperative follow-up period was 6.0-7.0 months. All skin grafts in the donor sites survived well. The thinned flaps of stage Ⅱ surgery achieved 100% in wound coverage rate. At 6 months after surgery, the colour and texture of the flaps were about the same as those of the normal skin of the upper limb. There were linear scars in both of donor and recipient sites. Four patients were satisfactory to the postoperative appearance and function of the donor site and 6 patients were very satisfactory. MHQ scores were 49-82 (mean, 74) points; DASH scores were 27-45 (mean, 32) points.Conclusion:Reconstruction of the wounds in wrist-forearm soft tissue defects of electrical burns with ALTF in staged surgery, can improve the function and aesthetics of the wrist-forearm. It is a good method.
