Objective To investigate the dietary intakes and weight retention status of postpartum women in Wuhan and explore the influence of dietary intervention on postpartum weight retention,providing scientific basis for rational dietary guid-ance to prevent excessive postpartum weight retention.Methods A total of 184 postpartum women at 42 days postpartum were included from September 2022 to April 2024 as participants and randomly divided into the control group(91 cases)and the inter-vention group(93 cases).Basic information on sociodemographic and lifestyle of the subjects were investigated,and body mass change was measured.The dietary intake was evaluated by the Da Ying Jia Intelligent Dietary Management System 2.0,and the overall dietary quality was evaluated by the alternate healthy eating index(AHEI).Individualized nutritional meal planning was provided to the intervention group,and follow-up was conducted to evaluate weight retention and the effect of dietary interven-tion at 3-month and 6-month postpartum.Results Compared with the body weight at inclusion,the average weight loss in the intervention group at 3-month postpartum was(0.95±2.38)kg,while the average weight loss in the control group was(0.14±1.44)kg.The average weight loss in the intervention group at 6-month postpartum was(2.29±3.64)kg,while the average weight loss in the control group was(0.04±2.99)kg.The weight retention rate in the intervention group(21.0％)was signifi-cantly lower than that in the control group(36.8％)(P＜0.05).Dietary analysis showed that at 3-month postpartum,the intake of egg and aquatic products in the intervention group was significantly higher than that in the control group(P＜0.05),and the AHEI score of white meat/red meat in the intervention group was significantly higher than that in the control group(P＜0.05).The intervention group would pay more attention to the intake of white meat when choosing meat.The intake of vegeta-bles and fungi/algae in both groups decreased at 6-month postpartum,but the decrease in the vegetables and fungi/algae score in the intervention group was significantly less than that in the control group,indicating that the intervention group was able to maintain healthy eating habits.Conclusion Dietary intervention for postpartum women can effectively reduce postpartum weight retention,promote postpartum recovery,and have a long-term improvement effect on their diet quality.

This study aims to describe the feasibility of inserting an oblique lumbar interbody fusion (OLIF) cage through biportal endoscopic lumbar interbody fusion (BE-LIF) and to illustrate the key surgical steps through a case-based video demonstration. BE-LIF is a safe and effective minimally invasive fusion technique. Among the factors influencing successful fusion, the cage footprint plays a critical role—a larger cage increases endplate contact area, maintains disc height, and enhances segmental stability. The OLIF cage offers these biomechanical advantages; however, inserting it through a biportal endoscopic approach is technically demanding and requires several strategic considerations. These include meticulous preoperative planning of portal positions to optimize visualization and working angles, adequate preparation of the disc space window for cage insertion, precise endplate preparation, and safe neural manipulation within a confined surgical field. A 56-year-old female presented with chronic low back pain and bilateral leg symptoms unresponsive to conservative treatment. Imaging revealed severe L4–5 central canal stenosis, foraminal narrowing, and instability. She underwent BE-LIF with OLIF cage insertion and percutaneous pedicle screw fixation. The step-by-step surgical video demonstrates portal placement, decompression, endplate preparation, bone grafting, and cage insertion under combined endoscopic and fluoroscopic guidance. The operation lasted 180 minutes, with an estimated blood loss of 150 mL. The patient was mobilized on postoperative day 1 and discharged on day 5 with marked improvement. Follow-up radiographs confirmed restoration of disc height, correct cage positioning, and adequate decompression. This case demonstrates that BE-LIF with OLIF cage insertion is feasible and may enhance fusion potential by combining the minimally invasive benefits of biportal endoscopy with the biomechanical advantages of a large-footprint cage. However, the procedure remains technically demanding and is best suited for experienced endoscopic spine surgeons.

Objective: Unilateral biportal endoscopic (UBE) treatment for lumbar disc herniation (LDH) is an advanced surgical procedure that has recently gained popularity. Numerous reports from developed countries have demonstrated the effectiveness of this minimally invasive technique. We evaluated the initial outcomes of UBE at a healthcare facility with limited resources. Methods: Clinical and radiographic data of 82 patients with LDH treated between July 2022 and June 2023 using UBE discectomy techniques, including the ipsilateral interlaminar approach, contralateral sublaminar approach, and paraspinal approach, were reviewed. Outcomes were analyzed in terms of the modified MacNab criteria, Japanese Orthopaedic Association (JOA) score, and visual analogue scale (VAS), with a mean follow-up of 3.1 months. Results: At the final follow-up, the mean VAS for low back pain improved from 4.5±1.0 to 1.2±0.4 and the VAS for leg pain improved from 7.8±0.9 to 1.6±0.5. The mean JOA score improved from 13.5±2.4 to 24.2±2.1. The modified MacNab criteria were excellent in 56 patients (68.3%), good in 22 (26.9%), and fair in 4 (4.8%). In total, 106 levels of LDH were treated. L4–5 disc herniation was performed in 55 patients (51.9%), L5–S1 in 36 (34.0%), L3–4 in 8 (7.5%), L2–3 in 6 (5.7%), and L1–2 in 1 (0.9%). The ipsilateral interlaminar approach was performed in 93 patients (87.7%), the contralateral sublaminar approach in 7 (6.6%), and the paraspinal approach in 6 (5.7%). Operative time significantly improved after performing 20 cases. In the early stage (1–20 cases), the operation time per level was 102.0±28.2 min, while in the next stage (21–82 cases) it was 78.1±20.4 minutes. No serious complications, including cauda equine syndrome or root palsy, were observed. Three patients had dural tears (2.8%), and 1 had epidural hematoma (0.9%). Conclusion UBE discectomy may be performed safely and effectively for the treatment of LDH in limited-resource settings.

A new flu caused by a novel influenza A(H1N1) virus has spread over the United States, Mexico and more than 40 other countries. And because of the immediate global concern, WHO has announced that the current level of influenza pandemic alert is raised to phase 5, indicating approaching of an influenza pandemic. As patients suffering from the influenza A (H1N1) have the similar symptoms as patients with seasonal influenza, differential detection and identification of the influenza virus have to depend on specific laboratory tests. We have successfully developed a RT-PCR based method for detection of the influenza A (H1N1) virus, and had applied the method to detection of clinical samples.
