Occipital lobe epilepsy （OLE） accounts for 5%-10% of all focal epilepsy cases. Ictal clinical symptoms mainly include visual and ocular movements， with common and specific elementary visual hallucinations. Electroencephalography has certain limitations， and a well-localized unifocal rhythmic ictal discharge during seizure is infrequent on ictal EEG. Detailed preoperative evaluation， especially the evaluation of symptoms and intracranial EEG monitoring， can help to obtain good outcomes after surgical treatment.

ObjectiveTo explore the effect of Yishen Tongluo prescription on sperm DNA fragmentation index （DFI） and sperm mitochondrial membrane potential （MMP） in patients with asymptomatic idiopathic asthenospermia infertility. MethodsA total of 128 patients with asymptomatic idiopathic asthenospermia were randomly assigned to an experimental group （64 cases） and a control group （64 cases）. The experimental group received Yishen Tongluo prescription， while the control group was treated with Wuzi Yanzongwan combined with L-carnitine oral solution. One treatment course lasted 12 weeks. Spouse pregnancy rate， sperm progressive motility （PR）， total sperm motility （PR+NP）， sperm function （sperm tail hypotonic swelling rate， sperm acrosin activity）， sperm DFI， and sperm MMP were compared between the two groups before and after treatment. Adverse reactions were observed and recorded during the study， and clinical efficacy and safety were systematically evaluated. ResultsA total of 121 patients completed the study， including 61 in the experimental group and 60 in the control group. The spouse pregnancy rate in the experimental group was 14.75% （9/61）， higher than that in the control group at 6.67% （4/60）， though the difference was not statistically significant. Clinical efficacy in the experimental group was superior to that in the control group （P<0.05）. Compared with the results before treatment， sperm PR， PR + NP， sperm tail hypotonic swelling rate， sperm acrosin activity， sperm DFI， and sperm MMP were significantly improved in both groups after treatment （P<0.05）， with greater improvements in the experimental group （P<0.05）. However， there was no significant change in sperm concentration in either group after treatment. During the study， no abnormal safety indicators or significant adverse reactions occurred in either group. ConclusionThe kidney-tonifying and collateral-dredging method shows good clinical efficacy in the treatment of asymptomatic idiopathic asthenospermia infertility. Yishen Tongluo prescription can improve sperm motility， increase spouse pregnancy rate， enhance sperm function， and demonstrates good safety. Its mechanism may be related to reducing sperm DFI and increasing sperm MMP.

Objective:To assess the feasibility of first polar body transfer (PB1T) combined with preimplantation mitochondrial genetic testing for blocking the transmission of a pathogenic mitochondrial DNA 8993T>G mutation.Methods:A Chinese family affected with Leigh syndrome which had attended the Reproductive Medicine Centre of the First Affiliated Hospital of Anhui Medical University in September 2021 was selected as the study subject. Controlled ovarian hyperstimulation was carried out for the proband after completing the detection of the mitochondrial DNA 8993T>G mutation load among the pedigree members. Mature MII oocytes were inseminated by intracytoplasmic sperm injection (ICSI), cultured in vitro for 5 to 6 days to the blastocyst stage, and trophoblastocytes were obtained by microbiopsy. Mitochondrial DNA testing (PGT-MT) and chromosomal aneuploidy (PGT-A) analyses were carried out after whole-genome amplification, and the embryos with zero mutation load were selected for transfer. Amniotic fluid and umbilical cord blood samples were collected during middle pregnancy and after birth respectively for mitochondrial DNA testing to verify the reliability of embryo screening. As an attempt, PB1 with good morphology of MⅡ oocytes was selected for transfer into the enucleated oocytoplasm from healthy donors, followed by ICSI fertilization, blastocyst culture and PGT of embryos using the same procedure. This study has been approved by the Ethics Committee of the First Affiliated Hospital of Anhui Medical University (No. 2021zhyx-B12). Results:An antagonist protocol was used for ovarian stimulation, and a total of 19 oocytes were obtained, of which 14 MⅡ were fertilized by ICSI, and 2 had developed into blastocysts. PGT-MT was carried out on biopsied trophoblastocytes, in which the mitochondrial DNA 8993T>G mutation load was not detected in one embryo, the other was 100% mutated, and the mutation loads of the remaining unfertilized eggs and developmentally arrested embryos ranged from 0% ~ 100%, presenting a clear biased distribution. With fully informed consent, one PGT-MT zero mutation load blastocyst was transferred and clinical pregnancy was achieved. Mitochondrial DNA and chromosomal testing of amniotic fluid cells during middle pregnancy had revealed no abnormalities. The proband had delivered a healthy boy through Caesarean section at 39+ 5 weeks of gestation, and no mutation was detected in the cord blood sample. Five well-formed PBs from 14 eggs were selected for PB1 transfer, followed by ICSI and culture, and two of the reconstituted embryos had formed blastocysts, with none of the above mutations detected in the biopsied samples.Conclusion:The PGT-MT technology can help families affected with mitochondrial diseases to have healthy offspring. PB1 transfer in combination with ICSI and PGT-MT holds the promise of turning waste into treasure and providing an alternative means of fertility for such families.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

OBJECTIVE: To explore the differences in clinical efficacy between enhanced workflows and express workflows in robotic-assisted total hip arthroplasty(THA). METHODS: A retrospective analysis was conducted on 46 patients who underwent robotic-assisted THA between November 2020 and May 2021. They were divided into the enhanced workflows group and the express workflows group based on the surgical methods. There were 20 patients in the enhanced workflows group, including 11 males and 9 females;aged from 51 to 78 years old with an average of (67.30±7.52) years old. The BMI ranged from 18.24 to 24.03 kg·m^-2 with an average of(23.80±3.01) kg·m^-2. There were 26 patients in the express workflows group, including 12 males and 14 females;aged from 57 to 84 years old with a mean age of (67.58±7.29) years old, and their BMI ranged from 19.72 to 30.08 kg·m^-2 with an average of (24.41 ±2.92) kg·m^-2. The operation time, hospital stay, and perioperative complications of the patients were recorded. The postoperative acetabular prosthesis anteversion angle, abduction angle, limb length, and offset distance data were measured. The Harris hip score at the latest follow-up was recorded. RESULTS: All patients completed the surgery as planned and were followed up, with the follow-up period ranging from 47 to 54 months with a mean of (49.78±1.85) months and the length of hospital stay ranging from 2 to 11 days with an average of (6.57±1.82 ) days. The operation time of enhanced workflows group was (93.41±16.41) minutes, which was longer than that of the express workflow groups (75.19±18.36) minutes, and the difference was statistically significant (P<0.05). In enhanced workflows group, the postoperative acetabular anteversion angle was (19.20±4.46)°, the limb length discrepancy was (-1.55±9.13) mm, and changes of the offset was (-5.15±6.77) mm. The corresponding values in express workflows group were (20.46±3.29)°, (2.19±4.39) mm, and (-2.39±4.34) mm, respectively. There was no statistically significant difference in these indicators between the two groups(P>0.05). One patient in the enhanced workflows group developed deep venous thrombosis after surgery. No cases of dislocation or periprosthetic infection. At the latest follow-up, all patients had well-positioned prostheses without loosening. Harris hip score was (90.50±1.67) points in enhanced workflows group and (90.73±2.36) points in the express workflows group, with no statistically significant difference between the two groups (P>0.05). CONCLUSION The clinical efficacy of robot assisted total hip arthroplasty technology is satisfactory. The enhanced workflows will increase the surgical time. For patients with normal anatomical hip joint disease, this study did not find significant advantages in joint stability and functional scoring for the enhanced workflows.

BACKGROUND: Neoadjuvant immunochemotherapy has emerged as an indispensable therapeutic modality for non-small cell lung cancer (NSCLC). However, its clinical application experience remains limited, and the associations between various clinical factors and treatment benefits remain undefined. This study aims to evaluate the efficacy and safety of neoadjuvant immunochemotherapy in patients with stage IB-IIIB NSCLC in a real-world setting, analyze survival outcomes among subgroups with diverse clinical characteristics, and identify potential clinical predictive factors for pathological response. METHODS: This study included patients with stage IB-IIIB NSCLC who underwent radical lung resection after 2-4 cycles of neoadjuvant immunochemotherapy at Peking University People's Hospital between August 2019 and March 2024. Medical records and follow-up information were collected to analyze therapeutic response, adverse events and survival outcomes. Logistic analysis was used to identify clinical predictors of pathological response. RESULTS: Among 183 enrolled patients, 116 (63.4%) were stage III. Grade 3-4 immune-related adverse events (irAEs) occurred in 39 (21.3%) patients. Radiographic complete response (CR) or partial response (PR) was achieved in 118 (64.5%) patients. R0 resection was achieved in 180 (98.4%) patients. Major pathologic response (MPR) was observed in 107 (58.5%) patients, with 78 (42.6%) achieving pathologic complete response (pCR). Squamous cell carcinoma and radiographic objective response were associated with pathological response (pCR/MPR). With a median follow-up of 22.1 [interquartile range (IQR): 18.3-32.2] months, the 2-year event-free survival (EFS) and overall survival (OS) rates were 82.5% and 90.4%, respectively. Achievement of pathological response (pCR/MPR) was correlated with prolonged survival outcomes. CONCLUSIONS Neoadjuvant immunochemotherapy is safe and effective for patients with stage IB-IIIB NSCLC. Patients achieving pCR or MPR exhibit significantly better survival benefits from neoadjuvant immunochemotherapy. Squamous cell carcinoma and radiographic objective response can serve as clinical predictors of pathological response.

Objective:To investigate the laboratory diagnostic value of 5 new blood routine indexes in chronic hepatitis B (CHB), liver cirrhosis and hepatocellular carcinoma (HCC).Methods:The retrospective study included 65 patients with chronic HBV infection, 72 patients with liver cirrhosis and 163 patients with HCC recruited at Liver Disease Center in First Affiliated Hospital of Fujian Medical University, as well as 52 healthy controls recruited from the Physical Examination Center of the First Affiliated Hospital of Fujian Medical University from October 2022 to April 2023. Five new parameters [early granulated cell percent (EGC%), early granulated cell absolute count (EGC#), microcytic anemia factor (MAF), leukocyte estimate(corrected)from the DIFF optical channel (WDOP) and leukocyte estimate(corrected)from the NRBC optical channel (WNOP)] were detected by UniCel DxH 900 blood cell analyzer. Univariate analysis of the expression levels of the 5 new parameterswere compared among CHB, liver cirrhosis and HCC groups. Pearson correlation analysis was used to explore the correlation between the 5 new parameters and HBV-related markers in CHB and Child-Pugh score in liver cirrhosis. Receiver operating characteristic (ROC) curve and AUC were used to estimate the diagnostic capacity of the 5 new blood routine indexes in CHB, liver cirrhosis and HCC.Results:In patients with CHB, the levels of EGC% ( Z=4.613, P<0.001) and EGC# ( Z=4.220, P<0.001) were higher than those of healthy controls; EGC# was positively correlated with HBsAg and HBeAg (both P<0.05). In patients with cirrhosis, the level of MAF ( Z=-4.928, P<0.001) was lower than that of healthy controls, and Child-Pugh score was found to be negatively correlated with MAF ( r=-0.349, P<0.05). In HCC patients, WDOP ( Z=2.45, P=0.017) and WNOP ( Z=2.90, P=0.017) levels were higher in patients with tumor volume>3 cm 3 than those in patients with volume ≤3 cm 3. The AUCs of combination of 5 new parameters to diagnose CHB, liver cirrhosis and HCC were 0.901 (95% CI 0.830-0.973, P<0.001), 0.946 (95% CI 0.909-0.984, P<0.001), and 0.904 (95% CI 0.858-0.950, P<0.001). Conclusions:The 5 new parameters based on peripheral blood cell analysis have good clinical value in the diagnosis of CHB, liver cirrhosis and HCC diseases.

Aim To observe the mechanism of salvian-olic acid B(SalB)against oxygen glucose deprivation/re-oxygenation(OGD/R)injury in H9c2 cardiomyo-cytes.Methods The protective concentration of SalB against OGD/R-injured H9c2 cardiomyocytes was screened by CCK-8 assay.The levels of lactate dehy-drogenase(LDH),aspartate transaminase(AST)and creatine kinase(CK)were detected by ELISA kit.The mechanism of action of SalB on OGD/R-injured H9c2 cardiomyocytes was explored using high-through-put sequencing of the transcriptome.The binding of SalB to differential proteins was assessed using molecu-lar docking assays.Fatty acid content was determined using free fatty acid kits.The relative expressions of mRNA and protein of differential genes were verified by RT-qPCR and Western blot.The causal relationship between the target of action of SalB and heart failure was examined by Mendelian randomization experiment.Results SalB protected OGD/R-injured H9c2 cardio-myocytes and significantly reduced the levels of CK,LDH and AST compared with the blank control group.One hundred differential genes were screened by tran-scriptome sequencing,which were mainly involved in fatty acid elongation,central carbon metabolism of cancer,tryptophan metabolism pathways.Molecular docking showed that SalB had good binding energy to differential proteins.The mRNA and protein expression of core differential genes Elovl6,Echs1 and Acot1 were consistent with the transcriptome sequencing results.SalB reduced fatty acidsafter OGD/R injury.Mende-lian randomization experiments suggested that SalB might reduce the risk of heart failure through fatty acid metabolism,thereby reducing the risk of heart failure.Conclusion SalB can protect H9c2 cardiomyocytes after OGD/R injury by down-regulating Elovl6,Echs1 and Acot1 expression through the fatty acid metabolism pathway.
