Objective: To investigate the efficacy,safety and feasibility of regional lymph node dissection in laparoscopic radical surgery for bladder cancer under the guidance of indocyanine green fluorescence imaging. Methods: A total of 30 patients with muscle invasive bladder cancer (T2/T3NxM0) who volunteered to enter the clinical trial were randomly divided into the indocyanine green imaging guided laparoscopic regional lymph node dissection group (n=15) and the standard pelvic lymph node dissection group (n=15).The number of positive lymph nodes,operation time,intraoperative bleeding volume,incidence of lymph leakage,and tumor recurrence and metastasis rate 2-year after surgery were collected. Results: The number of positive lymph nodes was (4.20±1.66) and (4.60±1.72) respectively in the indocyanine green and standard groups,with no statistically significant difference (P>0.05).There were no statistically significant difference in the tumor recurrence and metastasis rates 2-year after surgery between the two groups (P>0.05).However,the indocyanine green group had shorter operation time,less intraoperative bleeding volume,and lower incidence of lymphatic leakage than the standard group (P<0.05). Conclusion: Indocyanine green fluorescence imaging guided laparoscopic lymph node dissection has comparable clinical efficacy to standard lymph node dissection,but with fewer complications.

Objective:
To evaluate the clinical efficacy of preimplantation genetic testing for monogenic disorders(PGT-M) in families with hereditary epilepsy.
Methods :
Whole-exome sequencing(WES) and familial co-segregation analysis were performed to validate the pathogenicity of variants(PCDH19 c. 1031C > G and LGI1 c. 856T >G) in two monogenic epilepsy families. A clinical PGT-M pathway was implemented,and reproductive outcomes were tracked.
Results:
In Family 1(PCDH19 likely pathogenic variant),13 blastocysts were biopsied over two ovarian stimulation cycles,yielding 3 unaffected euploid embryos(23. 1%). After the third frozen embryo transfer,a healthy male infant was successfully delivered. Prenatal diagnosis confirmed that the fetus did not carry the pathogenic variant PCDH19. Family 2(LGI1 variant of uncertain significance,VUS) screened 14 blastocysts,identifying 2 unaffected euploid embryos(14. 3%),with the first transfer unsuccessful. A clinical pregnancy was currently ongoing following the second frozen-thawed embryo transfer(FET).
Conclusion
PGT-M can precisely block the vertical transmission of monogenic epileptic pathogenic variants,offering an effective reproductive intervention strategy for families with hereditary epilepsy.

Objective:
To investigate the impact of endometriosis on pregnancy and delivery outcomes in patients undergoing single euploid frozen_thawed blastocyst transfer cycles following preimplantation genetic testing.
Methods :
A retrospective analysis was performed on clinical data from patients undergoing frozen_thawed blastocyst transfer after preimplantation genetic testing at the reproductive center of The First Affiliated Hospital of Anhui Medical University. The endometriosis group comprised 84 treatment cycles. After 1 : 3 propensity score matching , 252 treatment cycles from non_endometriosis patients were included as the control group. General characteristics and clinical outcomes were compared between the two groups.
Results:
There were no statistically significant differences between the two groups in terms of general characteristics , human chorionic gonadotropin ( HCG) positive rate , cycle clinical pregnancy rate per cycle , early miscarriage rate , preterm birth rate , live birth rate per cycle , cesarean section rate , delivery weeks , cumulative clinical pregnancy rate , and cumulative live birth rate (all P > 0. 05) .
Conclusion
Endometriosis may not reduce the pregnancy rate and live birth rate in single frozen euploid blastocyst transfer cycles .

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.
