Objective:To investigate the selection of treatment methods for renal tumors in pilots as well as the clinical significance of robot-assisted surgery by summarizing the process of robot-assisted surgery in the treatment of renal cell carcinoma in a pilot.Methods:The diagnosis, robot-assisted surgery and aeromedical assessment of a pilot with renal cell carcinoma were reported, and the related literature was reviewed.Results:The patient was a 44-year-old male transporter pilot, who was diagnosed with a left renal mass in the middle-lower pole of the kidney during a routine abdominal CT scan. After detailed preoperative evaluation that ruled out the possibility of distant metastasis and other surgical contraindications, the patient underwent robot-assisted laparoscopic partial nephrectomy in August 2022. The postoperative recovery went well, and renal function remained within normal limits at follow-ups. In March 2023, the pilot was concluded as qualified for flight after aeromedical assessment.Conclusions:Robot-assisted partial nephrectomy can significantly reduce surgical trauma, lower the risk of complications, and maximally preserve renal function. It is a good approach to renal tumors in pilots who can recover quickly.

BACKGROUND:At present,measurement osteotomy technique and gap balance technique are the two main surgical methods in total knee arthroplasty.Both methods have their advantages and disadvantages.By adjusting the osteotomy angle,the gap balance technique can reduce the release of soft tissue and obtain a more balanced flexion and extension space.The clinical efficacy of gap balance technique is superior,but this surgical method lacks tools and is easily influenced by the surgeon's surgical experience and subjective judgment,with more errors.Measurement osteotomy technique has a short learning curve,but it relies on anatomic markers and is prone to many complications due to inaccurate positioning.In recent years,many instrument companies have successively developed and launched tools that can improve the quality of surgery.However,there are still few reports about the tool. OBJECTIVE:To compare the clinical efficacy of gap balance technique and measurement osteotomy technique under Offset Repo-Tensor in total knee arthroplasty,and explore the value of Offset Repo-Tensor in total knee arthroplasty. METHODS:The medical records of 85 patients with total knee arthroplasty were collected and divided into two groups according to the operation method.Group A consisted of 44 patients who underwent total knee arthroplasty using a gap balance technique combined with Offset Repo-Tensor.Group B consisted of 41 patients who underwent total knee arthroplasty using measurement osteotomy technique.Surgical time,American Knee Society Score,knee range of motion,changes in lower limb alignment,and postoperative complications were compared between the two groups to evaluate the clinical efficacy of gap balance technique combined with Offset Repo-Tensors in total knee arthroplasty. RESULTS AND CONCLUSION:(1)All 85 patients were followed up.(2)Postoperative knee range of motion in both groups was higher than that before surgery(P<0.05),and the improvement in group A was more significant than that in group B(P<0.05).(3)American Knee Society Score in both groups after surgery was higher than that before surgery(P<0.05),and the American Knee Society Score in group A was higher than that in group B at 2 weeks,1,3 months,and the last follow-up(P<0.05).(4)The operation time of group A was slightly shorter than that of group B,but the difference was not significant(P>0.05).(5)The lower limb alignment in both groups was improved after operation,but there was no significant difference between the two groups(P>0.05).(6)The complication rate of group A(2%)was lower than that of group B(7%),but there was no significant difference between the two groups(P>0.05).(7)It is indicated that compared with the measurement osteotomy technique,the combination of Offset Repo-Tensor and gap balance technique can elevate the clinical effect and improve the function and motion range of the knee joint.

Neuropathic pain is a chronic disease that severely afflicts the life and emotional status of patients, but currently available treatments are often ineffective. Novel therapeutic targets for the alleviation of neuropathic pain are urgently needed. Rhodojaponin VI, a grayanotoxin from Rhododendron molle, showed remarkable antinociceptive efficacy in models of neuropathic pain, but its biotargets and mechanisms are unknown. Given the reversible action of rhodojaponin VI and the narrow range over which its structure can be modified, we perforwmed thermal proteome profiling of the rat dorsal root ganglion to determine the protein target of rhodojaponin VI. N-Ethylmaleimide-sensitive fusion (NSF) was confirmed as the key target of rhodojaponin VI through biological and biophysical experiments. Functional validation showed for the first time that NSF facilitated trafficking of the Cav2.2 channel to induce an increase in Ca²⁺ current intensity, whereas rhodojaponin VI reversed the effects of NSF. In conclusion, rhodojaponin VI represents a unique class of analgesic natural products targeting Cav2.2 channels via NSF.

In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in chemotherapy. In this study, a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy (SERS). The Fe₃O₄@Au@Ag nanoparticles (NPs) deposited graphene oxide (GO) nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid (4-MPBA) to form SERS probes (GO-Fe₃O₄@Au@Ag-MPBA). Furthermore, doxorubicin (DOX) is attached to SERS probes through a pH-responsive linker boronic ester (GO-Fe₃O₄@Au@Ag-MPBA-DOX), accompanying the 4-MPBA signal change in SERS. After the entry into tumor, the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS signal. Thus, the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS spectra. Additionally, the strong T₂ magnetic resonance (MR) signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy (PTT). Altogether, this GO-Fe₃O₄@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting, pH-sensitive drug release, SERS-traceable detection and MR imaging, endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

Objective:To explore the effect of combining functional electric stimulation (FES) with upper limb cycle training in rehabilitating upper limb motor function and ability in the activities of daily living after a stroke.Methods:Sixty hemiplegic stroke survivors were randomly divided into an experimental group and a control group. In addition to conventional rehabilitation therapy, the experimental group underwent 20 minutes of MOTOmed upper limb cycle training every day while receiving FES. The control group received only the 20 minutes of cycle training. Before and after 4 weeks, Brunnstrom staging was used to quantify hand and upper extremity functioning. The Fulg-Meyer assessment upper extremity scale (FMA-UE) and the modified Barthel index (MBI) were also used before the training and after 1, 2, 3 and 4 weeks of the treatments.Results:After 4 weeks of treatment, significant differences were observed in the average BS scores of both groups compared with before the intervention. The average hand and upper limb stages of the experimental group were significantly better than the control group′s averages. Significant improvement was also observed in the average FMA-UE and MBI scores of both groups after only one week, with significantly greater improvement in the experimental group.Conclusions:Supplementing upper limb cycle training with FES can significantly improve the upper limb motor function and ability in the activities of daily living of stroke survivors. It is more effective than the MOTOmed exercise alone.
