Oocyte maturation disorders and fertilization failures are caused by a variety of factors, including complex factors such as chromosomal abnormalities and poor oocyte quality. With the widespread use of high-throughput sequencing technology, more and more genetic mutations have been found to be associated with oocyte maturation and fertilization process in infertile patients. This paper summarizes and discusses 11 key genes ( TRIP13, TBPL2, LHX8, PATL2, TUBB8, CDC20, WEE2, ZP, ASTL, JUNO and CD9) related to oocyte maturation and fertilization-related disorders in females, providing a basis for research on the prevention of diseases associated with oocyte maturation blockage and fertilization failure and the development of targeted therapies.

Objective:To elucidate the clinical and genetic characteristics of familial cases with Glucose transporter type 1 deficiency syndrome (Glut1DS).Methods:A survey of family history was conducted on children (proband) with Glut1DS who had visited Peking University First Hospital between November 2008 and April 2024 by focusing on the clinical manifestations of family members. Peripheral venous blood (2 mL) was collected from the pediatric patients and their parents. Genomic DNA was extracted and sequenced subsequently. Sanger sequencing was performed to validate the identified variant sites of the SLC2A1 gene in the probands and their family members. The pathogenicity of suspected variants was analyzed according to the 2015 American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants. The clinical features, auxiliary examinations, and mutational characteristics of family members with SLC2A1 variants were analyzed. This study has been approved by the Clinical Research Ethics Committee of Peking University First Hospital (Ethics No. 2021 Research 332). Results:Among 87 cases with Glut1DS, 10 families with autosomal dominate inherited cases were identified, accounting for 11.0% of the cases. Of the 11 children, 8 were boys and 3 were girls. The onset of the disease had ranged from 3 months to 120 months (median 6 months), with 4 cases of early-onset classic type, 2 cases of late-onset classic type, and 5 cases of non-classic type. Six children had seizures, and 7 exhibited movement disorders. Seven children underwent developmental assessment, of which 3 had mild developmental delay, 2 were borderline, and 2 were normal. Nine children underwent lumbar puncture. The cerebrospinal fluid glucose levels ranged from 1.45 to 2.25 mmol/L (median 1.86 mmol/L), and the cerebrospinal fluid to blood glucose ratios ranged from 0.29 to 0.44 (median 0.35). Among the 8 fathers with SLC2A1 gene variants, 4 were asymptomatic, 2 developed paroxysmal exercise-induced movement disorders (PED) in childhood and adulthood, respectively, 1 had poor memory since childhood, 1 developed migraines during adolescence, and his sister was an asymptomatic carrier. The father with childhood-onset PED had a cerebrospinal fluid test with CSF glucose of 1.85 mmol/L. Of the 3 mothers with SLC2A1 gene mutations, 1 was an asymptomatic carrier; 2 developed PED in childhood and after the age of 20 respectively. The mother who developed PED in childhood also had psychomotor developmental delay. Genetic testing results revealed that among 10 families, 8 carried missense variants, 1 carried a nonsense variant, and 1 carried a small fragment insertion leading to a frameshift variant. Among the 11 cases, SLC2A1 gene variants in 8 children were inherited from their fathers, while in 3 cases, the variants were inherited from their mothers. The pathogenicity of the genetic variants was evaluated according to the Standards and Guidelines for the Interpretation of Sequence Variants published by the ACMG. Among the 8 variants identified in the 10 families, 4 were classified as pathogenic variants, 1 as likely pathogenic, and 3 as variants of uncertain significance (VUS). Four variant sites induding, c. 204_205insTCTC (p.V69fs), c. 412G>C (p.G138R), c. 431T>G (p.V144G), and c. 875A>G (p.Y292C), were not previously reported in the literature. Among these, the latter three were categorized as VUS. Conclusion:Familial Glut1DS account for 11.0% of the cases in China, with the majority of SLC2A1 gene variants inherited from the fathers, predominantly missense mutations, and with an autosomal dominant inheritance pattern. Probands tend to have earlier onset and more severe symptoms than their parents, who often present with mild or no symptoms.

Objective:To explore the clinical efficacy of anterolateral thigh perforator flap (ALTPF) in treatment of extensive wound of Degree IV burns in limbs.Methods:A retrospective analysis was conducted on 9 patients who had extensive wound of Degree IV burns in limbs caused by stove burns admitted to Department of Burns and Plastic Surgery, the 988th Hospital of the Joint Logistics Support Force of the Chinese PLA between January 2017 and January 2024. Among the patients, there were 8 males and 1 female, aged between 36 and 63 years. Three patients had the wound from anterior leg to dorsal foot, 3 from leg down to ankle, 1 from forearm to hand and 2 from arm to forearm. Area of burns ranged from 20 cm × 15 cm to 30 cm × 25 cm, and all patients were treated by free ALTPF. According to whether the main artery at the recipient site was feasible for direct anastomosis with the vessels carried in flap, 4 patients were treated by bilateral parallel ALTPFs, and 5 were treated by unilateral ultra-long internally supercharged ALTPF. A total of 13 ALTPFs were harvested, with individual flap size at 20 cm × 8 cm to 46 cm × 12 cm. Donor sites were directly sutured. Time for flap harvesting, flap survival and wound healing time were records. Scheduled postoperative follow-up was conducted at outpatient clinic and via telephone interviews to evaluate functional recovery. Follow-up assessments included evaluation of flap condition, two-point discrimination (TPD), recovery of joint function at recipient sites, flap appearance and donor site recovery.Results:The time for flap harvest was 1.0 to 4.5 hours. All 13 ALTPFs successfully survived. The time from surgery to healing of recipient sites was 18 to 72 days, and all donor sites healed. Over the postoperative follow-up that lasted for 6 to 34 months, the recipient sites had found with good cosmetic outcomes, without osteomyelitis or deep tissue infection. Four ALTPFs in 2 patients were found swelling, which were revised at 6 months after surgery. Four ALTPFs in other 2 patients had pigment deposition at edges. One ALTPF was scalded, which healed after dressing changes but left with patchy scars. The remaining ALTPFs were soft, elastic, free from pain and well-perfused, with regained protective sensation at S 3. However, all of the ALTPFs failed to detect TPD. Six patients with lower limb injuries were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot scoring system: 2 patients were rated as excellent and 4 were rated as good. Three patients with upper limb injuries were evaluated using Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association: 1 patient was rated as excellent and 2 were rated as good. Only linear scars left at the 13 donor sites, with normal blood supply to the distal limbs, and without restrictions in range of motion of knee joints nor muscle strength of quadriceps. Conclusion:The ALTPF offers advantages such as anatomical consistency, reliable blood supply and flexible combination in treatment of extensive wound of Degree Ⅳ burns in limbs. It is an ideal surgical procedure for treatment of large soft tissue defects of extremities.

Objective:To explore the clinical efficacy of the first dorsal metatarsal artery pedicled lateral toe bilobed flap in repairing the finger pulp defects of two adjacent fingers.Methods:This study was a retrospective observational study. From January 2018 to December 2022, 9 patients with finger pulp defects in two adjacent fingers who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of the 988 th Hospital of Joint Logistics Support Force of PLA, including 6 males and 3 females, aged 26 to 48 years. The injured fingers were the index finger and middle finger (5 cases) or the middle finger and ring finger (4 cases). After debridement, the wound area of a single finger ranged from 1.2 cm×0.8 cm to 3.2 cm×2.8 cm. The finger pulp defects of two adjacent fingers were repaired with the first dorsal metatarsal artery pedicled lateral toe bilobed flap, and the two adjacent fingers were sutured together. The area of single flap ranged from 1.5 cm×1.0 cm to 3.5 cm×3.0 cm. The wound in the flap donor site was sutured directly or repaired with full-thickness skin graft from the groin region. The finger separation surgery was performed 3 weeks after surgery. The survival and blood supply of flaps, and survival of skin grafts and wound healing of the donor sites were observed after surgery. During follow-up, the texture, sliding, and shape of the flap, movement function of the finger, and the shape and function of the foot donor site were observed. At the last follow-up, the sensory of the flap was evaluated according to the sensory evaluation standard of the British Medical Research Council, and the hand function was evaluated according to the functional evaluation trial standard for severed finger replantation of the Hand Surgery Society of the Chinese Medical Association. Results:After surgery, all the flaps of 9 patients survived without vascular crisis. The flaps were soft in texture and good in shape. One patient had partial necrosis at the edge of the skin graft in the toe, and the wound healed after dressing change; the skin grafts in the toe in the other 8 patients survived, and the wounds healed well. During follow-up of 12 to 18 months after surgery, the flaps had soft texture, good elasticity, low sliding, and good shape. The finger movement function was normal. The wound in foot donor site recovered well without ulceration and deformity, and walking was not affected. At the last follow-up, the sensation of the flaps was sensitive, of which 8 flaps reached S3 and 10 flaps reached S3 + in sensation, and the two-point discrimination distance of the flaps was 9-13 mm. The functional scores of the affected fingers were 85 to 95, all of which were excellent. Conclusions:The first dorsal metatarsal artery pedicled lateral toe bilobed flap can repair finger pulp defects of two adjacent fingers at the same time, and the appearance, sensation, and function of the affected fingers recovered well after surgery, with less damage to the foot donor site. It is one of good methods to repair finger pulp defects of two adjacent fingers in clinic.

This study has been approved by the Clinical Research Ethics Committee of Peking University First Hospital (Ethics No. 2021 Research 332). RESULTS: Among 87 cases with Glut1DS, 10 families with autosomal dominate inherited cases were identified, accounting for 11.0% of the cases. Of the 11 children, 8 were boys and 3 were girls. The onset of the disease had ranged from 3 months to 120 months (median 6 months), with 4 cases of early-onset classic type, 2 cases of late-onset classic type, and 5 cases of non-classic type. Six children had seizures, and 7 exhibited movement disorders. Seven children underwent developmental assessment, of which 3 had mild developmental delay, 2 were borderline, and 2 were normal. Nine children underwent lumbar puncture. The cerebrospinal fluid glucose levels ranged from 1.45 to 2.25 mmol/L (median 1.86 mmol/L), and the cerebrospinal fluid to blood glucose ratios ranged from 0.29 to 0.44 (median 0.35). Among the 8 fathers with SLC2A1 gene variants, 4 were asymptomatic, 2 developed paroxysmal exercise-induced movement disorders (PED) in childhood and adulthood, respectively. 1 had poor memory since childhood, 1 developed migraines during adolescence, and his sister was an asymptomatic carrier. The father with childhood-onset PED had a cerebrospinal fluid test with CSF glucose of 1.85 mmol/L. Of the 3 mothers with SLC2A1 gene mutations, 1 was an asymptomatic carrier; 2 developed PED in childhood and after the age of 20, respectively. The mother who developed PED in childhood also had psychomotor developmental delay. Genetic testing results revealed that among 10 families, 8 carried missense variants, 1 carried a nonsense variant, and 1 carried a small fragment insertion leading to a frameshift variant.

Among the 8 variants identified in the 10 families, 4 were classified as pathogenic variants, 1 as likely pathogenic, and 3 as variants of uncertain significance (VUS). Four variant sites, including c.204_205insTCTC (p.V69fs), c.412G>C (p.G138R), c.431T>G (p.V144G), and c.875A>G (p.Y292C), were not previously reported in the literature. Among these, the latter three were categorized as VUS. CONCLUSION Familial Glut1DS account for 11.0% of the cases in China, with the majority of SLC2A1 gene variants inherited from the fathers, predominantly missense mutations, and with an autosomal dominant inheritance pattern. Probands tend to have earlier onset and more severe symptoms than their parents, who often present with mild or no symptoms.
