OBJECTIVES: To investigate the incidence of ipsilateral upper urinary tract stones after partial nephrectomy and its risk factors. METHODS: We retrospectively analyzed baseline patient characteristics (age, gender, and body mass index), smoking, alcohol consumption, comorbidities (hypertension, diabetes, hypertriglyceridemia, hyperuricemia, and cardiovascular diseases), preoperative tumor conditions (tumor diameter, multiple foci, location, hemorrhage, necrosis, cystic changes, and endophytic growth), preoperative glomerular filtration rate and intraoperative factors (renal collecting system damage, ischemia time, operation time, surgical approach, and estimated intraoperative blood loss) to identify the risk factors for ipsilateral upper urinary tract stones following partial nephrectomy in our center. RESULTS: The overall incidence of upper urinary tract stones following partial nephrectomy was 7.80% (112/1435). The incidence of ipsilateral upper urinary tract stones was significantly higher than those of contralateral stones (4.95% vs 1.46%, P<0.001) and bilateral stones (4.95% vs 1.39%, P<0.001). Intraoperative damage to the renal collecting system was identified as a significant risk factor for ipsilateral upper urinary tract stones (OR=4.550, 95% CI: 2.237-9.252, P<0.001). Diabetes was a probable risk factor for secondary ipsilateral upper urinary tract stones after partial nephrectomy (OR=2.419, 95% CI: 0.973-6.012, P=0.057). CONCLUSIONS The incidence of ipsilateral upper urinary tract stones after partial nephrectomy is higher than that of contralateral and bilateral stones. Intraoperative renal collecting system damage is a risk factor for secondary ipsilateral upper urinary tract stones after partial nephrectomy.

Osteoporosis is a prevalent skeletal condition characterized by reduced bone mass and strength, leading to increased fragility. Buqi-Tongluo (BQTL) decoction, a traditional Chinese medicine (TCM) prescription, has yet to be fully evaluated for its potential in treating bone diseases such as osteoporosis. To investigate the mechanism by which BQTL decoction inhibits osteoclast differentiation in vitro and validate these findings through in vivo experiments. We employed MTS assays to assess the potential proliferative or toxic effects of BQTL on bone marrow macrophages (BMMs) at various concentrations. TRAcP experiments were conducted to examine BQTL's impact on osteoclast differentiation. RT-PCR and Western blot analyses were utilized to evaluate the relative expression levels of osteoclast-specific genes and proteins under BQTL stimulation. Finally, in vivo experiments were performed using an osteoporosis model to further validate the in vitro findings. This study revealed that BQTL suppressed receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis and osteoclast resorption activity in vitro in a dose-dependent manner without observable cytotoxicity. The inhibitory effects of BQTL on osteoclast formation and function were attributed to the downregulation of NFATc1 and c-fos activity, primarily through attenuation of the MAPK, NF-κB, and Calcineurin signaling pathways. BQTL's inhibitory capacity was further examined in vivo using an ovariectomized (OVX) rat model, demonstrating a strong protective effect against bone loss. BQTL may serve as an effective therapeutic TCM for the treatment of postmenopausal osteoporosis and the alleviation of bone loss induced by estrogen deficiency and related conditions.

OBJECTIVE: To analyze the prevalence and burden of headache disorders in China and its provinces from 1990 to 2021. METHODS: Using data from the Global Burden of Disease Study (GBD) 2021, the number of prevalent cases, prevalence rate, disability-adjusted life years (DALYs), and age-standardized DALY rates were analyzed by sex, age group, and province for headache disorders and their subtypes (migraine and tension-type headache [TTH]) between 1990 and 2021. Percentage changes during this period were also estimated. RESULTS: In 2021, approximately 426 million individuals in China were affected by headache disorders, with an age-standardized prevalence rate of 27,582.61/100,000. The age-standardized DALY rate for all headache disorders was 487.15/100,000. Between 1990 and 2021, the number of prevalent cases increased by 37.78%, while the prevalence of all headache disorders, migraine, and TTH increased by 6.92%, 7.57%, and 7.86%, respectively. The highest prevalence was observed in the 30-34 age group (39,520.60/100,000). Migraine accounted for a larger proportion of DALYs attributable to headache disorders, whereas TTH has a greater impact on its prevalence. In 2021, the highest age-standardized DALY rates for headache disorders were observed in Heilongjiang (617.85/100,000) and Shanghai (542.86/100,000). CONCLUSION The prevalence of headache disorders is increasing in China. Effective health education, improve diagnosis and treatment are essential, particularly for middle-aged working populations and women of childbearing age.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

Objective:To design and evaluate the application value of intracavitary-interstitial brachytherapy (IC-ISBT) applicator template for locally advanced cervical cancer.Methods:MRI data of 100 patients with ⅡB-ⅣA stage cervical cancer (International Federation of Gynecology and Obstetrics 2018 staging system) before and after external beam radiation therapy (EBRT) admitted to Sun Yat-sen University Cancer Center from March 2019 to September 2020 were collected. The range of primary cervical lesions was retrospectively analyzed and compared. Based on the residual mass of patients, the corresponding high-risk clinical target volume (HR-CTV) was delineated, and the IC-ISBT applicator template was designed and initially applied to cervical cancer patients. Dosimetry analysis and efficacy evaluation were compared between the applicator template-guided ( n=37) and free-hand implantation groups ( n=63). Chi-square test or Fisher exact test was performed for categorical variables, and t-test or U-test for continuous variables. Results:The median distance between the residual tumor margin (clockwise 3, 6, 9, 12 o'clock) and the center of 100 patients with ⅡB-ⅣA stage cervical cancer after EBRT was 16.5, 14.0, 17.0 and 13.0 mm, respectively. The corresponding HR-CTV was superimposed to reconstruct the three-dimensional diagram, and the cylindrical IC-ISBT applicator template with mushroom-like head was designed and manufactured: the longest and shortest diameter of the head was 35 and 20 mm, respectively; the central channel was adapted to the uterine tube, the C1-C12 channels was arranged in inner circle, and the peripheral B1-B5 and A1-A4 pin channels were expanded bilaterally. In terms of dose coverage, there was no significant difference between the HR-CTV D 90% [(635.12±22.65) vs. (635.80±25.84) cGy], bladder D 2 cm3 [(473.79±44.78) vs. (463.55±66.43) cGy)], rectum D 2 cm3 [(396.99±73.54) vs. (408.00±73.94) cGy] and sigmoid colon D 2 cm3 [(293.07±152.72) vs. (311.31±135.77) cGy] between the template-guided and free-hand implantation groups (all P>0.05), but the HR-CTV D 98% was significantly higher [(544.78±32.07) vs. (536.78±32.04) cGy, P=0.007] and the rectum D 1 cm3 and D 0.1 cm3 were significantly lower [(438.62±69.65) vs. (453.97±67.89) cGy, P=0.016; (519.46±70.67) vs. (543.82±81.24) cGy, P=0.001] in the template-guided implantation group. In addition, there was no significant difference in the complete response rate between two groups (86% vs. 83%, P>0.05). Conclusions:This IC-ISBT applicator template is reasonably designed, and the therapeutic efficacy of the template-guided implantation is equivalent to that of free-hand implantation. The dose coverage of the target area meets the clinical demand with a better protection of the organs at risk. The applicator template has the potential to be widely used as a conventional template in clinical practice as the applicator-guided implantation is convenient to operate and repeat.

Objective:To investigate the safety and efficacy of low negative pressure fat suction combined with bipolar radiofrequency in repairing facial fat overfilling.Methods:A total of 29 patients with facial fat overfilling underwent low negative pressure fat suction combined with bipolar radiofrequency between February 2022 and October 2023 in Changsha My Like Medical Cosmetology Hospital. All patients were female. The mean age was 35.7 years (range, 25-51 years) and the mean body mass index was 20.3 (range, 16.8-24.3 kg/cm 2). The mean time after autologous fat transplantation was 53.4 months (range, 19-96 months). Postoperative patient satisfaction surveys were conducted, and 2 independent doctors evaluated clinical effect preoperative and postoperative photographs at 3-6 months postoperatively. Results:There were 29 cases (100%) underwent liposuction in the pre-zygomatic region, and the amount of fat was 4.1-12.6 (7.95±1.85) ml. There were 4 cases (13.8%) underwent liposuction in the forehead, and the amount of fat was 1.8-5.2 (2.75±0.50) ml. There were 7 cases (24.1%) underwent liposuction in the temporal region, and the amount of fat was 2.8-6.5 (3.86±1.07) ml. There were 8 cases (27.6%) underwent liposuction in the cheek, and the amount of fat was 5.2-10.5 (7.25±2.12) ml. There were 18 cases (62.1%) underwent liposuction in the perioral region, and the amount of fat was 3.7-9.5 (6.33±1.28) ml. The energy delivered by bipolar radiofrequency was 3.3-10.2 (5.71±2.27) KJ. 82.8% of patients were satisfied with their postoperative effect (24/29 patients). 86.2% of doctors were satisfied with the postoperative effect (25/29 patients). Two out of 29 patients (6.9%) developed irregularity by liposuction.Conclusions:Low negative pressure liposuction combined with bipolar radiofrequency can effectively reduce the fat, narrow the tissue gap and improve facial sagging, which is an effective method for repairing facial fat overfilling.

Objective:To explore the effect and safety of mesenchymal stem cell exosome microneedle introduction in the treatment of melasma.Methods:Thirty cases of female patients with stable melasma in the Department of Dermatology, Changsha Meilai Medical Beauty Hospital, aged (36±5) years and with a disease duration of (42.4±20.7) months, from July 2021 to July 2022, were retrospectively included. According to Fitzpatrick skin typing, 23 cases of type Ⅲ and 7 cases of type Ⅳ were included. All patients were locally anesthetized with lidocaine cream for 30 min, and rolled with a 0.5 mm needle in a zigzag pattern with even force, in the order of the right cheek, the left cheek, the forehead, the nose, the mandible, and the upper lip. During the rolling process, 3 ml of MSC exosome medical liquid wound dressing was applied to the facial skin, and after it was fully absorbed, exosome was locally readministered in the area of melasma. Treatment ended with a slight redness at the site of application. 1 MSC exosome wound dressing was appllied as a cold compress for 15 min after treatment. Treatment was given once every 2 weeks for 6 consecutive sessions. All the patients were followed up at 4 and 12 weeks after the last session, and the area and severity index of melasma (MASI) were scored before and after the treatment, the clinical efficiency and patient satisfaction rate and the incidence of adverse reactions were also counted.Results:At 4 and 12 weeks after the end of treatment, the skin color of all 30 patients was brighter than that before treatment, and no recurrence of melasma symptoms seen. At 12 weeks after the end of treatment, the decrease rate of MASI score was 66.1%, among which the decrease rate of MASI score in patients with type Ⅲ melasma was 63.9%, and the decrease rate of MASI score in patients with type Ⅳ melasma was 63.9%. Among the 30 patients, 1 case was cured, 25 cases showed obvious improved, 4 cases were improved, and no cases were ineffective, with an effective rate of 86.7% (26/30). Five patients were very satisfied, 18 patients were satisfied, 6 patients were generally satisfied, and 1 patient was dissatisfied; the patient satisfaction rate was 76.7% (23/30). No serious adverse reactions occurred in all patients.Conclusions:MSC exosome microneedle introduction is safe and effective in the treatment of melasma without serious adverse reactions.
