OBJECTIVES:
To summarize the clinical and genetic characteristics of end-stage renal disease caused by PLCE1 gene mutations.
METHODS:
A retrospective analysis of the clinical and genetic features of three children from a family with PLCE1 gene mutations was conducted, along with a literature review of hereditary kidney disease cases caused by PLCE1 gene mutations.
RESULTS:
The proband was an 8-year-old male presenting with nephrotic syndrome stage 4 chronic kidney disease. Renal biopsy showed focal segmental glomerulosclerosis. Two years and five months after kidney transplantation, the patient had persistent negative proteinuria and normal renal function. Whole-exome sequencing identified two pathogenic heterozygous variants: c.961C>T and c.3255_3256delinsT, with c.3255_3256delinsT being a novel mutation. Family screening revealed no renal involvement in the parents, but among five siblings, one brother died at age of 4 years from end-stage renal disease. A 7-year-old sister presented with proteinuria and bilateral medullary sponge kidney, with proteinuria resolving after one year of follow-up. A 3-year-old brother died after kidney transplantation due to severe pneumonia. The literature review included 45 patients with hereditary kidney disease caused by PLCE1 gene mutations. The main clinical phenotype was nephrotic syndrome (87%, 39/45), and renal pathology predominantly showed focal segmental glomerulosclerosis (57%, 16/28). No mutation hotspots were identified.
CONCLUSIONS
Compound heterozygous mutations in the PLCE1 gene can lead to rapid progression of the disease to end-stage renal disease, with favorable outcomes following kidney transplantation. Family screening is crucial for early diagnosis, and medullary sponge kidney may be a novel phenotype associated with these gene mutations.

OBJECTIVE:
To investigate the effect of hemoglobin (Hb) on the efficacy of chimeric antigen receptor T cell therapy (CAR-T) in patients with multiple myeloma (MM).
METHODS:
From June 2017 to December 2020, 76 MM patients who received CAR-T therapy in the Department of Hematology, The Affiliated Hospital of Xuzhou Medical University, with complete clinical data and evaluable efficacy, were selected as the research objects. According to the receiver operating characteristic (ROC) curve, the best cut-off value was obtained. The patients were divided into groups on the basis of Hb 105.5 g/L as the cut-off value. The age, sex, serum calcium, β2-microglobulin, serum creatinine, lactate dehydrogenase (LDH), and the influencing factors of CAR-T treatment efficacy in MM patients were analyzed.
RESULTS:
Hb was an influencing factor of efficacy. Univariate analysis showed that Hb, LDH, and albumin affected the efficacy of CAR-T therapy. Multivariate analysis showed that Hb ( OR=1.039, 95% CI: 1.002-1.078) and LDH ( OR=1.014, 95% CI: 1.000-1.027) were the influencing factors for the efficacy of CAR-T therapy.
CONCLUSION
The efficacy of CAR-T therapy in MM patients with low Hb is poor, and Hb is a factor affecting the efficacy of CAR-T therapy.

Objective: To examine the value of intravascular ultrasound (IVUS) for excimer laser ablation (ELA) combined with drug-coated balloon (DCB) in treating lower limb arteriosclerotic obliterans (ASO). Methods: As a prospective case series study, patients who underwent ELA combined with DCB for lower limb ASO with the guidance of IVUS from September 2021 to March 2022 at Department of Vascular Surgery, Zhongshan Hospital, Fudan University were enrolled prospectively. Lesion characteristics, procedure-related outcomes and complications were collected. The therapy outcomes were compared with baseline data by paired t test. Results: There were 8 males and 2 females, aged (72.0±5.9) years (range: 61 to 81 years). Of all the 11 lesions, there were 8 lesions in superficial femoral artery and 3 in popliteal artery. The lesion length was (7.0±2.4) cm (range: 3.2 to 9.8 cm). There were 4 chronic totally occlusion and 7 severe stenosis. All patients underwent the operation successfully. The technical success rate was 10/11. Bailout stenting was performed in one lesion because of flow-limiting dissection. Four lesions were grade 3 to 4 in peripheral artery calcium score system, and 9 lesions with calcification arc≥180°. Larger diameter drug-coated balloons were selected in 5 lesions after measurement of intravascular ultrasound. The follow-up time was (6.0±1.9) months (range: 3 to 9 months). The ankle-brachial index of the patient was significantly improved immediately after surgery (0.97±0.13 vs. 0.48±0.18, t=-7.60, P<0.01) and at 3 months after surgery (0.95±0.12 vs. 0.48±0.18, t=-7.17, P<0.01). The 3-month primary patency rate was 11/11, the target lesion reintervention was 0 and ulcer healing rate was 3/4. Conclusion: IVUS assisted ELA in the treatment of lower limb artery lesions is safe and effective in early stage.

OBJECTIVE:
To observe the effects of electroacupuncture at "Siguan" points on behavior, colonic 5-hydroxytryptamine (5-HT) and fecal short-chain fatty acids (SCFAs) in rats with post-stroke depression (PSD), and explore the effect mechanism of electroacupuncture at Siguan points on PSD.
METHODS:
Fifty SD rats were randomly divided into a sham-operation group, a stroke group, a PSD group, a drug group and an electroacupuncture group, with 10 rats in each one. The stroke model was established by middle cerebral artery occlusion (MCAO) method in the stroke group; except for the sham-operation group, the rats in the other groups were intervened with MCAO combined with solitary and chronic unpredictable mild stress (CUMS) to establish PSD model. In the electroacupuncture group, electroacupuncture was delivered at "Hegu" (LI 4) and "Taichong" (LR 3), with disperse-dense wave, 2 Hz/10 Hz in frequency, for 30 min in each intervention, once daily, for consecutive 21 days. Simultaneously, distilled water (0.01 L•kg-1•d-1) was administrated intragastrically. Fluoxetine solution (2.33 mg•kg-1•d-1) was given by gavage , once a day and for 21 days in the drug group. The same procedure of fixation and gavage with distilled water were adopted in the sham-operation group, the stroke group and the PSD group. Separately, before stroke modeling, after PSD modeling and after 21-day intervention, the consumption of sugar water and the scores of horizontal movement and vertical movement in open-field test were observed. After 21-day intervention, the content of colonic 5-HT was detected by immunohistochemical method, and that of fecal SCFAs was determined by gas chromatography mass spectrometry.
RESULTS:
After PSD modeling, compared with the stroke group, the sugar water consumption, the horizontal movement scores and vertical movement scores of the open-field test were all reduced in the PSD group, the drug group and the electroacupuncture group (P<0.05). After 21-day intervention, the sugar water consumption and the scores of horizontal movement and vertical movement of the open-field test were increased in the drug group and the electroacupuncture group (P<0.05) when compared with the PSD group; and the horizontal movement score in the electroacupuncture group was lower than that of the drug group (P<0.05). Compared with the sham-operation group, the contents of total fecal SCFAs and acetic acid were lower in the stroke group (P<0.05), and the contents of colonic 5-HT and total fecal SCFAs, acetic acid, propionic acid and butyric acid were reduced in the PSD group (P<0.05). In comparison with the PSD group, the contents of colonic 5-HT and total fecal SCFAs, acetic acid and propionic acid were increased in the drug group and the electroacupuncture group (P<0.05); and the content of colonic 5-HT in the electroacupuncture group was lower than that of the drug group (P<0.05). The level of colonic 5-HT was positively correlated with the contents of total fecal SCFAs and propionic acid (r=0.424, P=0.005; r=0.427, P=0.004).
CONCLUSION
Electroacupuncture at "Siguan" points can relieve the depression-like behavior of PSD rats, and its underlying mechanism may be related to the regulation of fecal SCFAs, which affects the release of colonic 5-HT.

Objective:To explore the genetic etiology and the value of early diagnosis of early onset epileptic encephalopathy (EOEE) with unknown etiology.Methods:A total of 60 children with EOEE of unknown etiology were prospectively enrolled in the outpatient and inpatient departments of Fujian Provincial Hospital from January 2018 to January 2021.Peripheral blood was collected prospectively for whole-exome sequencing and copy number variation (CNV) detection to analyze the clinical characteristics and genetic sequencing results of the children.Results:Twenty-four patients with EOEE-related pathogenic or suspected pathogenic mutations were detected, including infantile spasms (10 cases), Dravet syndrome (3 cases), pyridoxine-dependent epilepsy (1 case) and ohtahara syndrome (1 case), and unknown epileptic encephalopathy (9 cases). The onset age of EOEE-related patients ranged from 1 day to 11 months (median age was 4.2 months), the treatment age ranged from 2 days to 4 years (median age was 10 months), and the age of diagnosis was controlled within 1 month after treatment.There were 20 cases (33.3%) single gene variants and 4 cases (6.7%) CNV variants.A total of 13 genes were involved: KCNQ2, SCN1A, SCN8A, CACNA1E, CDKL5, PPP3CA, PCDH19, TSC1, TSC2, ZEB2, ALDH7A1, DCX and HNRNPU.The 4 CNV abnormalities were 17p13.3 deletion, 11q23.3q25 deletion, 1q36.31-p36.33 deletion, 1q43-1q44 deletion and Xp22.33 duplication, respectively.Totally, 20 mutations were new loci reported for the first time at home and abroad; 11q23.3q25 deletion that resulted in infantile spasm was first reported at home and abroad.Infantile spasm caused by ZEB2 mutation and epileptic encephalopathy caused by PPP3CA gene were both reported for the first time in China. Conclusions:Gene and CNV are important potential causes of children suffering from EOEE.When the etiology is unclear, the combination of whole-exome sequencing and CNV sequencing technology can improve the diagnosis level of genetic etiology of children with EOEE.The early genetic detection of these children can early diagnose and accurately treat epilepsy.

Objective: To examine the effect of excimer laser ablation (ELA) combining with drug-coated balloon (DCB) for atherosclerotic lesions in no-stenting zones (NSZ) of the lower extremity. Methods: From June 2019 to December 2021, 46 patients who underwent ELA combining with DCB in lesions of NSZ at Zhongshan Hospital, Fudan University and Jinshan Hospital, Fudan University were retrospectively enrolled, including 29 males and 17 females. The age was (72.5±11.7) years (range: 42 to 93 years). Among them, 44 lesions (95.7%, 44/46) were in popliteal artery and 2 lesions (4.3%, 2/46) were in common femoral artery. Chronic total occlusion (CTO) was observed in 31 patients (76.4%, 31/46), and stenotic lesions were observed in 15 patients (32.6%, 15/46). The length of lesions was (7.3±2.7) cm (range: 3.0 to 13.2 cm). Patients were followed at 6, 12 months after surgery and every year thereafter, and they underwent Doppler and CT angiography examination at each follow-up point. The primary endpoint was primary patency. The secondary endpoints included major amputation-free survival (MAFS) rate, technical success, bailout stent, ankle-brachial index (ABI), target lesion reintervention (TLR). Student t test was applied to compare the difference between ABI of 6 or 12 months after surgery and the baseline. Primary patency, freedom from TLR, and MAFS rate were calculated by Kaplan-Meier method. Results: The technical success rate was 91.3% (42/46). The rate of procedure-related complication was 6.5% (3/46), and all the complications were distal embolization. The rate of flow-limiting dissection was 8.7% (4/46). ABI was significantly increased at 6 and 12 months compared to preoperatively (0.90±0.10 vs. 0.42±0.10, t=-4.48, P<0.01; 0.87±0.12 vs. 0.42±0.10, t=-5.21, P<0.01). The follow-up time[M(IQR)] was 22.5 (8.8) months (range: 6 to 32 months). TLR was performed in 4 patients (4/46, 8.7%). The 2-year primary patency was 86.2% (95%CI: 71.8% to 93.5%). The 2-year freedom from TLR and MAFS rate were 90.7% (95%CI: 77.0% to 96.4%) and 97.8% (95%CI: 85.6% to 99.7%), respectively. Conclusion: ELA combining with DCB can be applied to treat atherosclerotic lesions in NSZ.
