Objective:To understand the epidemiological characteristics of mpox epidemic in Guangzhou and provide scientific evidence for the prevention and control of the disease.Methods:Based on the mpox surveillance system in Guangzhou, suspected mpox cases with fever and rash were reported by local hospitals at all levels to centers for disease control and prevention in Guangzhou for sampling, investigation and diagnosis. Descriptive epidemiological analysis was conducted on the clinical characteristics and treatment of the mpox cases and positive detection rate reported in Guangzhou as of 24:00 on June 23. Whole genome sequencing of the virus isolates was performed using Illumina Miniseq high-throughput sequencing platform.Results:The first mpox case in Guangzhou was reported on June 10 in 2023. As of 24:00 on June 23, a total of 25 confirmed mpox cases were reported. All the mpox cases were men with a M( Q1, Q3) of 32 (26, 36) years, the majority of the cases were MSM (96.0%). The main clinical features were rash (100.0%, 25/25), lymphadenectasis (100.0%, 25/25) and fever (52.0%, 13/25). Rash usually occurred near the genitals (88.0%, 22/25). The close contacts, mainly family members (40.4%, 23/57), showed no similar symptoms, such as fever or rash. The positive rate of mpox virus in household environment samples was 30.5%. The analyses on 3 complete gene sequences of mpox virus indicated that the strains belonged to West African type Ⅱb clade, B.1.3 lineage. Conclusions:Hidden transmission of mpox virus had occurred in MSM in Guangzhou. However, the size of affected population is relatively limited, and the possibility of wide spread of the virus is low.

Objective:To investigate the efficacy of oblique lumbar interbody fusion (OLIF) combined with percutaneous transforaminal endoscopic decompression (PTED) and posterior pedicle fixation through Wiltse approach in the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis.Methods:From June 2017 to February 2022, 103 patients (50 males and 53 females) of lumbar spondylolisthesis accompanied with lumbar spinal stenosis were performed with OLIF combined with PTED and posterior pedicle fixation. The mean age was 64.1±5.2 years (range, 42-87 years). All involved cases were single-segment and included 83 cases of L 4, 5, 17 cases of L 3, 4, and 3 cases of L 2, 3. Among them, 94 cases were performed for the first time, and other 9 were revision surgery treated by posterior lumbar laminectomy previously. The visual analog scale (VAS) was used to evaluate the low back pain and leg pain, and the Oswestry disability index (ODI) was used to evaluate the lumbar function. The VAS and ODI scores were recorded respectively before the operation, at discharge, 1, 3, 6 months after the operation and at the last follow-up. Macnab criteria was used to evaluate the clinical efficacy at the last follow-up. At the same time, imaging measurements were conducted, including the anterior and posterior disc height, segmental lordotic angle, percentage of slip on lateral X-ray film and the vertebral canal area on axial MRI before and after surgery. Results:All of 103 patients were successfully operated in one stage with an average operation time of 177.7±21.5 min (range, 155-220 min), and an average intraoperative blood loss of 55.9±18.3 ml (range, 30-150 ml). The mean follow-up time were 15.1±2.6 months (range, 6-36 months). There were significant differences in both VAS scores of back and leg and ODI scores at each postoperative time point when compared with preoperative ( F=508.25, F=1524.82, F=1148.68, P<0.001). Macnab criteria of the last follow-up was evaluated as follow: excellent in 85 cases, good in 14, fair in 4, and the excellent and good rate was 96.1%. The radiographic results showed the mean immediate postoperative anterior disc height, posterior disc height, segmental lordotic angle, percentage of slip and axial area of the vertebral canal were 15.23±2.97 mm, 9.32±2.31 mm, 14.36°±4.18°, 3.89%±3.11%, 113.37±47.27 mm 2, and thus all of those increased significantly compared to the mean preoperative 11.93±3.17 mm, 7.21±2.03 mm, 6.15°±3.99°, 23.66%±7.79%, 57.63±28.91 mm 2, respectively ( t=7.84, t=7.07, t=14.91, t=27.62, t=9.68, P<0.001). All cases achieved bony fusion during 6-12 months after operation. The incidence of surgery-related complications was 10.7% (11/103). There were 3 cases of end plate fracture and 2 cases of dural injury, which had no complaint after operation. There was 1 case of pedicle screw entering into the spinal canal by mistake, and the symptoms of nerve damage appeared after operation. After 1 year it basically returned to normal. There were 2 cases of thigh numbness and 1 case of psoas major weakness after operation, all of which relieved after 4 weeks. There was 1 case continuous pain of abdominal incision after surgery. There was 1 case of cage subsidence at the last follow-up. Conclusion:OLIF combined with PTED and posterior pedicle fixation through Wiltse approach is a minimally invasive surgical method for the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis. With the combined minimally invasive techniques, the decompression, fusion and fixation of the lumbar spine can be fulfilled perfectly. It has the advantages of minimally invasive, good clical outcome, few complications and rapid rehabilitation.

Osteotomy around the knee includes medial opening wedge high tibial osteotomy (HTO), lateral closing wedge HTO, lateral opening wedge distal femoral osteotomy (DFO), medial opening wedge DFO, and double-site osteotomy. Osteotomy redistributes the knee joint pressure by correcting the lower limb alignment, which can effectively delay the progression of knee osteoarthritis. Currently, three methods are used to determine the intraoperative osteotomy angle: the pre-drilling method, wedge block insertion method, and angle-guided linkage method. Coronal plane accuracy is evaluated using the hip-knee-ankle (HKA) angle, medial proximal tibial angle (MPTA), and ratio of lower limb weight-bearing line, while sagittal plane accuracy is assessed by measuring the posterior tibial slope (PTS). Individualized osteotomy guide plate can enhance osteotomy accuracy. The preparation process includes: (1) importing low-dose CT data of both lower limbs in DICOM format into reconstruction software to establish a 3D model of both lower limbs; (2) determining the osteotomy plane and distraction angle through threshold segmentation, importing the plate model, and establishing the length and position of each screw; (3) using fused deposition modeling to layer materials through a nozzle to create the 3D object. Individualized osteotomy guide plate in osteotomy around the knee can not only improve the accuracy of surgery, but also reduce the intraoperative fluoroscopy times and the incidence of complications. The operation efficiency and postoperative rehabilitation are better than those of traditional surgery. With the continuous upgrading of new materials and the improvement of design concepts, the accuracy and efficiency of individualized osteotomy guide will be further improved. Future research will focus on improving the degree of personalization of guide plate design and simplifying the manufacturing process.

Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.
