Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH). Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at Beijing Chaoyang Hospital, Capital Medical University from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided TELD (Ng-TELD) group (30 cases), while those treated with the conventional x-ray fluoroscopy method were defined as the control group (31 cases). Record and compare baseline characteristics, surgical parameters, efficacy indicators, and adverse events between the 2 patient groups. Results: The average follow-up duration for the 61 patients was 11.8 months. Postoperatively, both groups exhibited significant relief from back and leg pain, which continued to improve over time. At the final follow-up, patients’ lumbar function and quality of life had significantly improved compared to preoperative levels (p < 0.05). The Ng-TELD group had significantly shorter total operation time (58.43 ± 12.37 minutes vs. 83.23 ± 25.90 minutes), catheter placement time (5.83 ± 1.09 minutes vs. 15.94 ± 3.00 minutes), decompression time (47.17 ± 11.98 minutes vs. 67.29 ± 24.23 minutes), and fewer intraoperative fluoroscopies (3.20 ± 1.45 vs. 16.58 ± 4.25) compared to the control group (p < 0.05). There were no significant differences between the groups in terms of efficacy evaluation indicators and hospital stay. At the final follow-up, the excellent and good rate of surgical outcomes assessed by the MacNab criteria was 98.4%, and the overall adverse event rate was 8.2%, with no statistically significant differences between the groups (p > 0.05). Conclusion This study demonstrates that the integrated optical and magnetic surgical navigation system can reduce the complexity of TELD, shorten operation time, and minimize radiation exposure for the surgeon, highlighting its promising clinical potential.

OBJECTIVE: To investigate the relationship among seminal oxidation-reduction potential (nORP), sperm DNA fragmentation (DFI) and semen parameters in patients with varicocele. METHODS: Clinical data of 522 patients treated in the reproductive andrology clinic of the Northern Theater General Hospital from November 2023 to December 2023 were retrospectively analyzed, including 435 men of childbearing age and 87 men of infertile age. The patients were divided into the varicocele group (n=116) and non-varicocele group (n=406) according to clinical diagnosis. The differences of seminal plasma nORP, DFI, sperm high DNA stain ability (HDS) and semen parameters were analyzed between the two groups. The relationship among general clinical data, seminal plasma nORP, semen parameters, DFI and HDS in patients with varicocele were further analyzed. According to the severity of varicocele, the patients were divided into three groups, including mild, moderate and severe. And the differences of seminal plasma nORP and semen parameters, DFI and HDS among all groups were analyzed. The differences of seminal plasma nORP, semen parameters, DFI and HDS were compared between the varicocele and non-varicocele groups. RESULTS: The total sperm count, sperm concentration, progressive motility sperm percentage (PR%) and normal sperm morphology rate (NSMR) in patients with varicocele were significantly lower than those in control group (P<0.05). And seminal plasma nORP, DFI and HDS in patients with varicocele were significantly higher than those in control group (P<0.05). Seminal plasma nORP in patients with varicocele was significantly negatively correlated with total sperm, sperm concentration and NSMR (P<0.05), and significantly positively correlated with DFI and HDS (P<0.05). There were significant differences in nORP, total sperm count, sperm concentration, PR%, DFI and HDS among mild, moderate and severe varicocele groups (P<0.05). Seminal plasma nORP, sperm concentration, PR% and DFI in severe group were significantly lower than those in mild and moderate groups(P<0.05). Sperm count and HDS in severe group were significantly lower than those in mild group (P<0.05). In infertile patients, seminal plasma nORP, DFI and HDS in varicocele group were significantly higher than those in control group (P<0.05). And PR% in varicocele group was significantly lower than that in control group (P<0.05). CONCLUSIONS Seminal plasma nORP in patients with varicocele may be an important marker of oxidative stress affecting DFI and semen parameters.

Zishen Huoxue decoction (ZSHX) enhances cardiomyocyte viability following hypoxic stress; however, its upstream therapeutic targets remain unclear. Network pharmacology and RNA sequencing analyses revealed that ZSHX target genes were closely associated with mitophagy and apoptosis in the mitochondrial pathway. In vitro, ZSHX inhibited pathological mitochondrial fission following hypoxic stress, regulated FUN14 domain-containing protein 1 (FUNDC1)-related mitophagy, and increased the levels of mitophagy lysosomes and microtubule-associated protein 1 light chain 3 beta II (LC3II)/translocase of outer mitochondrial membrane 20 (TOM20) expression while inhibiting the over-activated mitochondrial unfolded protein response. Additionally, ZSHX regulated the stability of beta-tubulin through Sirtuin 5 (SIRT5) and could modulate FUNDC1-related synergistic mechanisms of mitophagy and unfolded protein response in the mitochondria (UPR^mt) via the SIRT5 and -β-tubulin axis. This targeting pathway may be crucial for cardiomyocytes to resist hypoxia. Collectively, these findings suggest that ZSHX can protect against cardiomyocyte injury via the SIRT5-β-tubulin axis, which may be associated with the synergistic protective mechanism of SIRT5-β-tubulin axis-related mitophagy and UPR^mt on cardiomyocytes.

Objective:To discuss the clinical features and prognostic factors of adrenal metastases.Methods:The clinical data of 37 patients with adrenal metastases admitted to the First Affiliated Hospital of Guangxi Medical University from May 2015 to August 2022 were retrospectively analyzed. There were 30 males and 7 females. The median age was 54 (43, 62) years old, including 13 cases aged ≥60 years old and 24 cases aged < 60 years old. There were 22 cases of right metastasis, 12 cases of left metastasis and 3 cases of bilateral metastasis. The maximum diameter of metastatic carcinoma was <3 cm in 10 cases, 3-6 cm in 18 cases, and >6 cm in 9 cases. There were 20 cases of synchronous metastasis (diagnosed with adrenal metastasis at the same time as the primary tumor) and 17 cases of metachronous metastasis (found after the diagnosis of primary tumor). There were 20 cases of adrenal metastasis alone and 17 cases of adrenal metastasis combined with other distant metastasis. 16 cases underwent adrenalectomy, 15 cases underwent adrenalectomy combined with other organ resection, and 6 cases underwent ultrasound-guided needle biopsy. 18 patients were treated with surgery alone, and 19 patients were treated with combined treatment (surgery, chemotherapy, radiotherapy, immunotherapy, targeted therapy, interventional therapy and seed implantation). There were 12 cases of hepatocellular carcinoma, 8 cases of renal clear cell carcinoma, 5 cases of lung adenocarcinoma, 2 cases of colon adenocarcinoma, 2 cases of neuroblastoma, 1 case of renal pelvis carcinoma, 1 case of gastric adenocarcinoma, 1 case of cholangiocarcinoma, 1 case of renal papillary cell carcinoma, 1 case of colon adenosquamous carcinoma, 1 case of thymic small cell carcinoma, 1 case of endometrial carcinoma, and 1 case of diffuse large B-cell lymphoma. The Kaplan-Meier method was used to draw the survival curve, the log-rank test was used to analyze the relationship between the clinical characteristics of patients and overall survival (OS) and progression-free survival (PFS), and the Cox proportional hazards regression model was used to analyze the factors affecting OS.Results:The median follow-up time of the 37 patients was 10 (4, 18.5) months.The overall survival rates at 6 months, 1 year and 2 years were 59.5% (22/37), 43.2% (16/37) and 32.4% (12/37), respectively. The 6-month, 1-year and 2-year overall survival rates of 18 patients who underwent surgery alone were 66.7% (12/18), 44.4% (8/18) and 27.8% (5/18), respectively. The 6 months, 1 year and 2 years overall survival rates of 19 patients with comprehensive treatment were 52.6% (10/19), 42.1% (8/19) and 36.8% (7/19), respectively. There was no significant difference in overall survival rate between the two groups ( P=0.773). Kaplan-Meier survival curve analysis showed that the side of metastatic cancer was a risk factor for OS ( P=0.012) and PFS ( P=0.013), and the time of diagnosis of metastatic cancer was a risk factor for OS ( P=0.021). Univariate Cox regression analysis showed that, time to diagnosis of metastases ( HR=2.5, 95% CI 1.1-5.4, P=0.021), side of metastases ( HR=3.6, 95% CI 1.5-8.5, P=0.004), pulmonary metastases ( HR=3.6, 95% CI 1.1-11.0, P=0.032) and adenocarcinoma of the primary tumor ( HR=3.2, 95% CI 1.2-8.8, P=0.025) were risk factors for OS. Multivariate Cox regression analysis showed that simultaneous presence of metastases ( HR=2.6, 95% CI 1.1-6.2, P=0.033) and metastases located on the left side ( HR=3.6, 95% CI 1.5-8.6, P=0.005) were independent risk factors for OS. Conclusions:Hepatocellular carcinoma is the most common pathological type of adrenal metastases in this study. Patients may benefit from combined therapy based on surgery. The time of diagnosis, side, tumor origin and pathological type of primary tumor are the prognostic factors of adrenal metastases. Simultaneous presence of metastases and left-sided metastases are independent risk factors for OS in patients with adrenal metastases.

AIM: To compare the clinical efficacy, vault, and rotational stability of horizontal, oblique, and vertical implantation of Toric implantable collamer lens(TICL).METHODS: Retrospective cohort study. A total of 92 cases(120 eyes)who underwent TICL implantation from July 2018 to March 2022 and had regular follow-up for at least 1 a postoperatively(1 d, 1 wk, 1, 3, 6 mo, and 1 a)at Wuhan Bright Eye Hospital were collected. The patients were divided into three groups, with 34 cases(45 eyes)in horizontal implantation group, 25 cases(29 eyes)in oblique implantation group(29 cases), and 33 cases(46 eyes)in vertical implantation group. Uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), diopters, vault, and rotation angle(deviation of the actual axis of TICL from the expected axis).RESULTS: All surgeries were uneventful, and there were no complications such as infection, secondary glaucoma, or cataract opacity. Safety and efficacy of the surgery: the CDVA of the three groups of patients was better than or equal to the preoperative CDVA at 1 a postoperatively, and there was no statistically significant differences in postoperative UDVA and CDVA of the three groups(P>0.05). The safety index at 1a postoperatively was 1.34±0.21, 1.34±0.17, and 1.31±0.18 for the horizontal, oblique, and vertical groups, respectively. The efficacy index was 1.26±0.21, 1.33±0.18, and 1.27±0.16 for the three groups, respectively, both with no statistically significant differences(P>0.05). Vault: there was a significant difference in postoperative vault among the three groups(P=0.003), with the vertical group having the lowest vault, followed by the horizontal group and the oblique group. The vaults at different follow-up time points within each group showed significant differences(P<0.001), and all decreased over time. Residual astigmatism: there was no significant difference in residual astigmatism among the three groups(P=0.130), but there were differences at different follow-up time points within each group(P<0.001). Rotation angle: no significant differences in rotation angle were observed among the three groups(P=0.135), but there were differences at different follow-up time points within each group(P<0.001).CONCLUSION: The implantation of TICL in different orientations has good safety and efficacy, the postoperative rotational stability is good, and the appropriate angle can be selected to implant TICL according to the clinical situation.

BACKGROUND:The repair and clinical outcome of bone defects remains a hot and difficult area of clinical research,which is a common problem that plagues clinicians.Constructing suitable,reproducible and infinitely close to clinical animal experimental models and their scientific evaluation are essential for further clinical treatment of related diseases. OBJECTIVE:To retrospectively analyze the preparation methods and characteristics of common animal models of femoral bone defects and to assess their strengths and weaknesses,thereby providing some reference for relevant researchers to select appropriate animal models of femoral bone defects. METHODS:PubMed,Web of Science,Medline,and CNKI were retrieved for relevant literature published from January 1,2000 to August 1,2022.The keywords were"bone defect,bone,bones,defect,defects,defective,animal model,animal,model,laboratory,laboratory animal,animal laboratory"in English and"bone defect,animal model,experiment"in Chinese. RESULTS AND CONCLUSION:Twenty-seven randomized controlled animal experiments involving rats,mice,New Zealand rabbits,and sheep were included,analyzed and assessed.The most common types of bone defects were cylindrical bone defects and segmental osteotomy bone defects,generally found in the middle and distal femur.These models are mostly used to evaluate the effects of bone repair materials,drugs,drug-loaded active substances and physical therapy on bone defect repair and explore defect healing mechanisms,particularly the weight-bearing bone defect repair mechanism.Different defect kinds and femoral bone defect ranges have been found in different animal experiments.Researchers can select the suitable animal model and bone defect type based on the goal of the experiment and then set an acceptable bone defect value.Current studies have shown that cylindrical and segmental osteotomy-induced bone defects,mainly in the distal and middle femur,are mostly used in the animal models of femoral bone defects and that the surgical methods and postoperative management are more mature and operable to provide mature experimental animal models.In terms of cylindrical bone defects,rats and New Zealand rabbits are more suitable,whereas segmental osteotomy has no special requirements and all types of animals can meet the experimental requirements.
