OBJECTIVE:
To evaluate the effectiveness of tibial nerve transection with epineurial suture and division of the common plantar digital nerve branches in the treatment of congenital macrodactyly in children.
METHODS:
A retrospective analysis was conducted on clinical data from 9 children with congenital macrodactyly who met the selection criteria and were admitted between January 2018 and December 2024. The cohort included 4 boys and 5 girls, aged 1-6 years (median, 3 years). Syndactyly of the second and third toes was present in 2 patients. Hypertrophy distribution was as follows: 1 case of single-ray involvement, 4 of double-ray, 1 of triple-ray, 1 of quadruple-ray, and 2 of quintuple-ray. Preoperatively, 7 cases exhibited limitations in both active and passive flexion and extension of the affected toes; in 2 cases, active movement was restricted while passive motion remained intact. All 9 children were unable to wear standard-sized footwear for the unaffected foot. Six presented with a limp, and 3 had difficulty walking. All 9 cases were moderate to severe progressive macrodactyly, and the growth rate of the affected foot was significantly faster than that of the healthy side. Six cases had undergone prior surgical interventions at other institutions, but disease progression continued postoperatively. All 9 patients underwent tibial nerve transection with epineurial suture and selective division of the common plantar digital nerve branches. At last follow-up, the foot growth rate was calculated (compared with that immediately after operation), and the changes of plantar pain sensation in the affected foot were detected before operation, immediately after operation, and at last follow-up, and the surgical efficacy was evaluated based on improvements in shoe fit and gait function.
RESULTS:
All 9 children were followed up 6-36 months, with an average of 18 months. All the incisions healed by first intention, and no infection or plantar ulceration occurred. At last follow-up, the growth rate of the affected foot was 0.10 (0.04, 0.14) cm/month, which was significantly slower than that of the healthy foot [0.14 (0.08, 0.18) cm/month] ( Z=3.951, P<0.001). Preoperatively, plantar pain sensation was absent in all cases; it was restored immediately after operation. At last follow-up, 6 patients had absent pain sensation, 2 had partial preservation (involving certain toes and central plantar regions), and 1 patient (with 3-year follow-up) exhibited regained sensation in multiple plantar areas. Gait improved in most cases, in which 8 children achieved normal ambulation, while 1 continued to limp due to leg-length discrepancy. Surgical efficacy were rated as excellent in 1 case, good in 7, and fair in 1.
CONCLUSION
Tibial nerve transection with epineurial suture combined with selective division of the common plantar digital nerve branches effectively reduces the growth rate of congenital macrodactyly in children, has minimal impact on plantar sensory function, and does not result in plantar ulcers or impaired ambulation.

Objective To evaluate the safety, effectiveness and feasibility of robotic-assisted kidney transplantation (RAKT). Methods Clinical data of 16 patients who underwent kidney transplantation were collected. Among them, 8 recipients received RAKT (RAKT group) and 8 cases underwent open kidney transplantation (OKT) with the contralateral kidney from the same donor (OKT group). Perioperative status and the recovery of renal allograft function were compared between two groups. Results All patients successfully completed the surgery. In the RAKT group, no patient was converted to open surgery. The operation time in the RAKT group was longer than that in the OKT group (P=0.015). No significant differences were observed in the serum creatinine levels before surgery and upon discharge between two groups (both P>0.05). In the OKT group, one recipient developed delayed graft function (DGF), and the remaining recipients did not experience perioperative complications. No significant difference was noted in the short-term recovery of renal allograft function between two groups (P>0.05). Conclusions Postoperative recovery of the recipients in the RAKT group is equivalent to that of their counterparts in the OKT group. RAKT is a safe and effective procedure for the team expertise in kidney transplantation.

BACKGROUND:The effect of electroacupuncture on the proliferation and differentiation of hippocampal oligodendrocytes in model mice with Alzheimer's disease remains poorly understood while demyelinating reaction related to oligodendrocytes is a common pathological reaction of Alzheimer's disease. OBJECTIVE:To investigate the effects and mechanism of electroacupuncture stimulation of"Baihui"(GV 20),"Fengfu"(GV 16)and bilateral"Shenshu"(BL 23)in Alzheimer's disease model mice on the proliferation and differentiation of endogenous neural stem cells to neurons and oligodendrocytes. METHODS:Forty 6-week-old SPF APP/PS1 transgenic male Alzheimer's disease model mice were randomly divided into electroacupuncture group(n=20)and Alzheimer's disease model group(n=20).Healthy male C57BL/6J mice of the same age were used as normal controls(n=20).The mice in the electroacupuncture group received electroacupuncture at"Baihui"(GV 20),"Fengfu"(GV 16)and bilateral"Shenshu"(BL 23)for 16 weeks(20 minutes/day and one day off a week).After electroacupuncture,Morris water maze was used to detect the changes of learning and memory function.Immunohistochemistry was utilized to detect hippocampal dentate gyrus β-amyloid senile plaques.The expression of BrdU/NeuN and BrdU/GALC in the hippocampal dentate gyrus was detected by immunofluorescence double labeling.Western blot assay was used to detect the expression levels of neuron specific protein Nestin and oligodendrocyte specific protein GALC in the hippocampus.mRNA and protein levels of Notch1 and Hes1 in the hippocampus were detected by real-time fluorescence quantitative PCR and western blot assay. RESULTS AND CONCLUSION:(1)Compared with the normal control group,the ability of learning and memory in the Alzheimer's disease model group decreased significantly;hippocampal dentate gyrus β-amyloid senile plaques increased significantly(P<0.01);the expression of GALC and Nestin in the hippocampus decreased significantly(P<0.01,P<0.05).(2)Compared with the Alzheimer's disease model group,the learning and memory ability of the electroacupuncture group was significantly increased;β-amyloid senile plaque in the hippocampal dentate gyrus decreased significantly(P<0.01).BrdU/NeuN double labeled positive cells in the hippocampal dentate gyrus and Nestin protein expression in the hippocampus increased significantly(P<0.01,P<0.05);GALC expression in hippocampus increased significantly(P<0.01).The mRNA and protein levels of Notch1 in the hippocampus were significantly increased(P<0.05,P<0.01).The mRNA and protein levels of Hes1 in the hippocampus decreased significantly(P<0.05).(3)These findings indicate that electroacupuncture at"Baihui"(GV 20),"Fengfu"(GV 16)and bilateral"Shenshu"(BL 23)of the Alzheimer's disease model infant mice can promote the proliferation and differentiation of endogenous neural stem cells to neurons and oligodendrocytes,which may be regulated through the Notch1/Hes1 pathway.
