Objective:To analyze the genetic and clinical characteristics, treatment and prognosis of patients diagnosed with maturity onset of diabetes of the young (MODY) 12 subtype.Methods:This retrospective study collected and analyzed data from 5 children with MODY12 subtype caused by ABCC8 gene variants who underwent inpatient and outpatient genetic testing at Beijing Children′s Hospital from January 2016 to December 2023. Their clinical and genetic features, treatment, and follow-up results were analyzed.Results:Among the 5 patients with MODY12 subtype, 4 were male and 1 was female, with an age of 13.4 (5.5, 14.6) years. Four of the patients were born large for gestational age, while one was born small for gestational age. Two patients were overweight or obese. Three patients exhibited typical symptoms of diabetes, while 2 were incidentally found to have elevated blood glucose level. One patient was found to have diabetic ketoacidosis at onset, who was diagnosed with congenital hyperinsulinism during the neonatal period and received diazoxide treatment, and experienced intellectual developmental delay. All 5 patients had autosomal dominant inherited diabetes within 3 generations. The fasting blood glucose at onset was 7.5 (6.5, 10.0) mmol/L, the haemoglobin A1c (HbA1c) was 11.8% (7.5%, 13.5%), and the fasting C-peptide was 1.2 (1.1, 2.2) μg/L. The duration of follow-up was 15 (9, 32) months. One patient underwent lifestyle intervention, 2 received metformin orally, 1 received insulin therapy, and the other received subcutaneous injection of insulin combined with sulfonylurea orally. At the last follow-up, the median fasting blood glucose was 6.1 (5.1, 7.0) mmol/L, the HbA1c was 5.9% (5.7%, 7.1%), and the fasting C-peptide was 1.7 (0.9, 2.9) μg/L. One patient developed diabetic retinopathy. There were 4 missense variations in ABCC8 gene and one in-frame deletion, all of which were maternally inherited heterozygotes.Conclusions:MODY12 subtype is a heterogeneous disorder with the age of onset from infancy to adolescence. It can present as mild hyperglycemia or diabetic ketoacidosis, and has a high incidence of obesity. Definitive diagnosis can be achieved through genetic test, and individualized treatment is recommended based on glucose levels.

Objective:To observe any stimulatory effect of intermittent theta burst stimulation (iTBS) on the cerebral swallowing cortex and the cerebellar swallowing motor area and to explore the related mechanisms.Methods:Forty-four healthy right-handed subjects were divided at random into a dominant cerebellum group ( n=15), a non-dominant cerebellum group ( n=15) and a control group ( n=14). In the dominant cerebellum group, iTBS was administered to the cerebellum of the dominant hemisphere, and the other hemisphere was given sham stimulation. In the non-dominant cerebellum group, it was the opposite. The dominant cerebellum received the sham stimulation. In the control group both hemispheres received sham stimulation. Before and after the stimulation, single-pulse transcranial magnetic stimulation (TMS) was applied to the representative regions of suprahyoid muscles in bilateral brain and cerebellum to observe changes of the latency and amplitude of motor evoked potentials (MEPs). Results:After the intervention the MEP amplitude of the bilateral swallowing cortex and the stimulated cerebellum had increased in the non-dominant cerebellum group, with increased MEP amplitude only from the stimulated cerebellum of the dominant cerebellum group. Compared with the control group, the non-dominant cerebellum group showed the greatest improvement in MEP amplitude of the stimulated bilateral cerebral cortex and cerebellum. Improvement in the dominant cerebellum group was significantly smaller. However, there were no significant differences in MEP latency or the percentage change in MEP latency from baseline among the three groups.Conclusions:Applying iTBS to either the non-dominant or the dominant cerebellum excites the brain areas related to swallowing, but in different ways.

The article reports a rare case of isolated persistent left superior vena cava (PLSVC) found during the catheterization of a dialysis catheter in an end-stage renal disease patient and the occurrence of guidewire entrapment in Chiari net. The patient was scheduled to have emergency dialysis due to end-stage renal disease and acute left heart failure. And a tunnel-cuffed catheter (TCC) for dialysis insertion was planned. Isolated PLSVC was found firstly by the imaging process. Then the guidewire was entrapped at the right atrium in the further operation. During the operation of the guidewire, the guidewire loosened and withdrawn with a fine fiber, which was considered a possibility of Chiari net. In the follow-up after one week, the TCC worked well, and the heart function improved after dialysis.

Background Procymidone (PCM) exposure can cause damage to reproductive organs of male mice, but whether its mechanism is related to the retinoic acid (RA) signaling pathway is unclear. Objective To explore the possible mechanism of PCM-induced testes damage in adolescent mice. Methods Three-week-old ICR mice (n=64) were randomly divided into a control group and three dose groups (low, medium, and high), with 16 mice in each group. PCM was administered orally at 0, 50, 100, and 200 mg·kg−1·d−1 for 21 consecutive days. Serum and bilateral testes in each mouse were collected to detect content of testosterone in serum and to observe histological changes in testis section after the mice were sacrificed one week after cessation of drug administration. Real-time fluorescence quantitative PCR and Western blotting were used to detect the mRNA expression abundances of genes related to the RA signaling pathway and apoptosis genes Casp9 and Casp12, and the protein expression levels of CYP26A1, ALDH2, and CASP9 respectively. Results Compared with the control group, there was no significant change in the overall appearance and testicular appearance of mice in each dose group after the PCM exposure. According to pathological section observation, the testicular seminiferous tubules of mice in the low-dose group showed slight atrophy and reduced sperm production; the testes of mice in the medium- and the high-dose groups showed obvious pathological damage (e.g. dilated lumen of seminiferous tubules, damaged spermatogenic epithelium, decreased number of spermatogonia, and partial absence of sertoli cells); as the concentration of PCM increased, the degree of spermatogenic epithelial damage in mice gradually increased and the number of spermatozoa in the seminiferous tubules decreased. There were no significant differences in the distance between the anus and the genitals, testicular mass, testicular volume, and testicular organ coefficient among the four groups of mice (P>0.05). The body weights of the mice in the low-, medium-, and high-dose groups were (34.91±1.89), (34.88±1.75), and (32.94±1.37) g respectively, and that in the high-dose group was lower than that in the control group, (35.93±1.99) g, (P<0.05); the serum testosterone concentrations were (313.77±5.32), (305.31±3.47), and (304.80±5.28) pg·mL−1 respectively, which were lower than that in the control group, (319.05±1.92) pg·mL−1 (P<0.05); as the dose of PCM increased, the body weight and serum testosterone concentration showed decreasing trends. The mRNA expression levels of Stra6 and Rbp1 in the high-dose group were higher than those in the control group (P<0.05); the mRNA expression levels of Aldh2, Aldh1a1, Aldh1a3, Rarα, Rar
