OBJECTIVE:
To observe the effects of Xingnao Kaiqiao acupuncture technique (for regaining consciousness and opening orifice) on methylation of N6-methyladenosine (m6A), and key methyltransferases and demethylases, so as to clarify the mechanism of acupuncture on cerebral ischemia-reperfusion injury (CIRI).
METHODS:
Of 68 male Sprague-Dawley rats of SPF grade, 15 rats were randomly selected as a sham-operation group, and the remaining rats were subjected to the model of middle cerebral artery occlusion using the suture ligation. CIRI was induced by ischemia for 2 h followed by reperfusion. Rats that failed to modeling or died were excluded. The rest 45 rats were randomly divided into three groups, i.e. model group, acupuncture group, and non-point acupuncture group, with 15 rats in each group. The rats in the acupuncture group were treated with acupuncture at bilateral "Neiguan" (PC6) and "Shuigou" (GV26). In the non-point acupuncture group, acupuncture was delivered at three non-points, located 3 mm below the bilateral midaxillary line and 3 mm lateral to the tip of the coccyx. One intervention was operated in these two acupuncture groups and the needles were retained for 30 min. Before modeling start and 2 h after ischemia, a laser speckle flowmeter was used to monitor the cerebral blood perfusion. In 2 h of ischemia and 24 h of reperfusion, the neurological behavioral score was evaluated. The volume of rat cerebral infarction was determined by triphenyltetrazolium chloride (TTC) staining, and the level of m6A methylation in ischemic cortical area was detected by Dot blot, and the protein and mRNA expression of the demethylase i.e. fat mass and obesity-associated protein (FTO), AlkB homolog 5 (ALKBH5) and key methyltransferases, i.e. methyltransferase-like 3 (METTL3), methyltransferase-like 14 (METTL14), and Wilms' tumor 1-associated protein (WTAP) in ischemic cortical area were detected by Western blot and real-time PCR.
RESULTS:
Cerebral blood perfusion decreased by>70% after 2 h ischemia. Compared with the sham-operation group, the neurobehavioral score and the percentage of cerebral infarction volume increased in the model group (P<0.01); the level of m6A methylation in the ischemic cortical area increased (P<0.01), the protein and mRNA expression of FTO decreased (P<0.01), and that of ALKBH5, METTL3, and METTL14 increased (P<0.01, P<0.05) in the model group. When compared with the model group and the non-point acupuncture group, the acupuncture group showed a decrease in the neurobehavioral score and the percentage of cerebral infarction volume (P<0.01), the level of m6A methylation in the ischemic cortical area was reduced (P<0.01, P<0.05), and the protein and mRNA expression of FTO was elevated (P<0.01).
CONCLUSION
Xingnao Kaiqiao acupuncture technique presents its protective effect on the brain in the rats with CIRI, which is related to up-regulating the expression of FTO and modulating m6A methylation.

Objective:To investigate the epidemiological characteristics and trends of birth defects related to assisted reproductive technology (ART) in Jiangxi Province from 2014 to 2023, and to explore the correlation factors of birth defect occurrence.Methods:A retrospective collection of ART treatment data and follow-up results from January 2014 to December 2023 across 18 reproductive centers in Jiangxi Province was conducted. The trend of birth defects and the rank order of defect types were analyzed. Exact probability methods were used to estimate the 95% confidence intervals ( CI) of the incidence rates, and Poisson regression was applied to identify independent correlation factors. Results:A total of 65 003 ART offspring were included in this study, comprising 2 025 offspring from intrauterine insemination (IUI) and 62 978 from in vitro fertilization and embryo transfer (IVF-ET). The overall incidence of birth defects was 13.46‰ (95% CI: 12.59‰-14.38‰), with 9.38‰ (95% CI: 5.66‰-14.61‰) for IUI and 13.59‰ (95% CI:12.70‰-14.53‰) for IVF-ET. The incidence of birth defects showed a decreasing trend from 2014 to 2023 (17.11‰ to 11.47‰, Ptrend=0.003). The top three birth defect types were circulatory system defects (3.71‰, 95% CI: 3.25‰-4.21‰), musculoskeletal system defects (2.37‰, 95% CI: 2.01‰-2.77‰), and congenital malformations of the face, ears, eyes, and neck (1.23‰, 95% CI: 0.98‰-1.53‰). Univariate analysis indicated that male offspring from IVF-ET had a higher incidence of birth defects than that in female offspring (14.72‰ vs. 12.31‰, P=0.009). Additionally, gestational age, birth weight, fetal number, cause of infertility, and year of delivery were significantly associated with birth defect incidence in IVF-ET offspring ( P<0.001, P<0.001, P<0.001, P=0.025, P=0.037). Multivariate analysis showed that in singleton pregnancies, male offspring, gestational age 32-36 weeks birth weight <1 500 g, and infertility with bilateral factors were independent risk factors for birth defects ( OR=1.21, 95% CI: 1.00-1.47, P=0.046; OR=1.90,95% CI: 1.41-2.56, P<0.001; OR=3.37, 95% CI: 1.33-8.51, P=0.010; OR=1.38, 95% CI: 1.12-1.69, P=0.003), while in multiple pregnancies, male offspring, gestational age <32 weeks, gestational age 32-36 weeks, birth weight <1 500 g, birth weight 1 500-2 499 g, maternal age 25-29 years and maternal age 30-34 years were independent risk factors ( OR=1.25, 95% CI: 1.03-1.52, P=0.023; OR=2.06, 95% CI: 1.35-3.15, P=0.001; OR=1.32,95% CI: 1.05-1.66, P=0.016; OR=1.98,95% CI: 1.19-3.28, P=0.009; OR=2.06,95% CI: 1.64-2.60, P<0.001; OR=2.00, 95% CI: 1.31-3.06, P=0.001; OR=1.90,95% CI: 1.24-2.92, P=0.003). Conclusion:Over the past 10 years, the incidence of birth defects in ART offspring in Jiangxi Province has shown a decreasing trend annually, with circulatory system malformations being the most common. The occurrence of birth defects in IVF offspring is primarily associated with maternal and infant characteristics, such as gender, gestational age, birth weight, number of fetuses, and cause of infertility, independent of ART treatment factors.

Objective:To retrospectively evaluate the clinical efficacy and safety of total 3D laparo-scopic ileal ureters replacement for bilateral ureters combined with bladder augmentation in patients with post-radiotherapy long-segment bilateral ureteral strictures and contracted bladder.Methods:Clinical data of two patients(aged 72 and 54 years)with radiation-induced long-segment bilateral ureteral stric-tures and reduced bladder capacity,treated at the Sixth Affiliated Hospital of Jinan University from Octo-ber 2023 to June 2024,were analyzed.Both presented with bilateral flank pain,recurrent chills/fever,urinary frequency,and urgency.Preoperative ureteral stricture lengths were measured as follows:left 10.4 cm and right 8.7 cm in the first case;left 10.6 cm and right 11.7 cm in the second case.Bladder capacity assessed by nephrostomy-assisted antegrade urography was 90 mL and 130 mL respectively.Both underwent single-position,one-stage totally 3D laparoscopic bilateral ileal ureteral replacement and blad-der augmentation based on membrane anatomy principles,with regular postoperative follow-up.Results:Procedures were completed by the same experienced urologist.Operative times were 420 min and 355 min,with intraoperative blood loss of 50 mL(no transfusion required).Postoperative bowel function re-sumed at the end of 4.5 and 3 days.No major perioperative complications occurred.Ureteral stents were removed at 2 months postoperatively,with imaging showing improved hydronephrosis,unobstructed ure-teral drainage,symmetrical bladder morphology,and smooth walls.Postoperative bladder capacities were 230 mL and 250 mL.Follow-up durations were 10 and 8 months.Both patients experienced significant relief of flank pain and lower urinary tract symptoms.No complications(enteric fistula,urinary fistula,or metabolic acidosis)were observed.At the final follow-up,one patient had mildly elevated serum cre-atinine,while the other showed reduced levels compared with preoperative values;both remained stable.Conclusion:Membrane anatomy-based dissection facilitates safe mobilization of fibrotic ureters with mini-mal bleeding and collateral damage.Total intracorporeal 3D laparoscopic ileal ureters replacement for bi-lateral ureters combined with bladder augmentation effectively addresses long-segment ureteral obstruction and improves bladder capacity.This approach is technically safe and feasible,though further validation with larger clinical cohorts is warranted.
