Objective:To analyze the hearing outcomes of high-risk children of diabetic mothers, especially in the subtypes of pre-pregnancy diabetes and gestational diabetes, in order to provide some reference for clinical practice. Methods:The basic characteristics and hearing levels of children whose mothers had a history of diabetes during pregnancy and underwent audiological diagnosis and evaluation at our hospital's Children's Hearing Diagnosis Center from January 2003 to June 2024 were analyzed. T-tests, Wilcoxon rank-sum tests, and chi-square tests were used for inter-group comparisons, with a significance level set at P<0.05. Results:A total of 285 children（570 ears） of diabetic mothers were included. Hearing loss was found in 310 ears, and the incidence of hearing loss was 54.39%（310/570）. The mean ABR threshold in the pregestational diabetes group was（50.01±29.29） dB HL, while that in the gestational diabetes group was（44.13±26.19） dB HL. The degree of hearing loss in the pregestational diabetes group was more severe than that in the gestational diabetes group（χ²=10.000, P=0.019）. Conclusion:Maternal history of diabetes may be one of the risk factors for hearing loss in their offspring, and the risk of hearing loss in children whose mothers had diabetes before pregnancy may be higher than that in the gestational diabetes group. It is suggested that the clinical practice should pay attention to the monitoring and follow-up management of the hearing status of such children, so as to improve the auditory outcomes of children born to diabetic mothers.

Objective:To observe the clinical efficacy and safety of Jianpi Bushen Jiedu Prescription combined with 5-fluorouracil (5-FU)-based chemotherapy and targeted therapy for the treatment of advanced colorectal cancer patients with liver and kidney yin deficiency combined with spleen deficiency pattern.Methods:A randomized controlled trial was conducted. A total of 72 hospitalized patients with advanced colorectal cancer treated at the Department of Oncology, Nanjing Hospital of Traditional Chinese Medicine Affiliated to Nanjing University of Chinese Medicine from October 2022 to January 2024 were enrolled as study subjects. Using a random number table method, they were allocated into two groups, with 36 patients in each group. The control group received the mFOLFOX6/FOLFIRI combined with bevacizumab regimen, while the treatment group was administered additional oral Jianpi Bushen Jiedu Prescription on the basis of the control group. Two weeks was a cycle in both groups, with a total of 6 cycles of treatment. Serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), and carbohydrate antigen 724 (CA724) were detected using electrochemiluminescence; the Karnofsky Performance Status (KPS) scale was utilized to evaluate patients' functional status; vital signs were continuously monitored, and adverse reactions were recorded. The short-term efficacy and TCM syndrome efficacy of patients were evaluated.Results:The treatment group demonstrated higher objective response rate (ORR) [31.25% (10/32) vs. 21.88% (7/32), χ2=0.72] and disease control rate (DCR) [84.38% (27/32) vs. 71.88% (23/32), χ2=1.46] compared to the control group, without statistical significance ( P>0.05). Post-treatment levels of CEA [4.09 (3.31,8.57) μg/L vs. 10.07 (4.55,22.35) μg/L, Z=-2.10] and CA72-4 [4.54 (2.04,10.99) mU/L vs. 9.48 (4.34,18.95) mU/L, Z=-2.52] in the treatment group were significantly lower than those in the control group ( P<0.05). The total effective rate of TCM syndrome was significantly higher in the treatment group [78.13% (25/32)] compared with the control group [50.00% (16/32)], with statistical significance ( χ2=5.50, P=0.019). Post-treatment KPS scores in the treatment group [80.0 (80.0, 80.0) vs. 70.0 (62.5, 80.0), Z=-2.76] were significantly higher compared with the control group ( P<0.01). During the treatment period, the treatment group showed statistical significance compared with the control group in the incidence of hemoglobin decrease ( χ2=4.66), leukopenia decrease ( χ2=4.27), and peripheral neuropathy ( χ2=3.93), with statistical significance ( P<0.05). Conclusion:The addition of Jianpi Bushen Jiedu Prescription to 5-FU-based chemotherapy combined with targeted therapy demonstrates significant clinical benefits in advanced colorectal cancer patients, including reducing tumor marker levels, alleviating clinical symptoms, improving quality of life, and mitigating treatment-related toxicities, with a good safety.

Objective:To investigate the application of 3.0T high resolution magnetic resonance imaging(HR-MRI)in acute ischemic stroke(AIS)and the influence factors of prognosis.Methods:A total of 92 AIS patients who underwent treatment in Hainan General Hospital from January 2019 to June 2022 were selected as the research objects.All patients were treated by thrombolytic therapy,and they were divided into favorable prognosis group(mRS scores≤2 points,n=66)and poor prognosis group(mRS score>2 points,n=26)according to modified Rankin Scale after they received 90d treatment.All of patients underwent Magnetom Trio type of 3.0 T HR-MRI examination within 1 week after they hospitalized,and the changes of luminal stenosis rate,the luminal area at the narrowest point,the plaque load,T2WIsignal intensity index,T1WI signal intensity index,plaque enhancement rate and other parameters were compared.The receiver operating characteristics(ROC)curve was adopted to analyze the predictive value of 3.0T HR-MRI parameters on the AIS prognosis.Binary Logistic regression model was used to analyze the risk factors that affected the prognosis of AIS patients.Results:The difference of infarction diameter between two groups was statistically significant(x2=6.574,P<0.05).The lumen area at the narrowest point in the poor prognosis group was significantly lower than that in the favorable prognosis group,while the T2WI signal intensity index,T1WI signal intensity index and plaque enhancement rate in the poor prognosis group were significantly higher than those in the favorable prognosis group(t=-3.378,4.443,4.413,3.890,P<0.05),respectively.ROC curve analysis showed that the area under curve(AUC)values of T2WI signal intensity index,T1WI signal intensity index,lumen area at the narrowest point and plaque enhancement rate in predicting the AIS prognosis were respectively 0.743,0.739,0.706 and 0.748.The Logistic regression analysis showed that infarction diameter>3.0cm,T1WI signal intensity index,T2WI signal intensity index,lumen area at the narrowest point and plaque enhancement rate were respectively independent risk factors that could affect AIS prognosis(OR=3.889,257.151,105.073,4.091,1.121,P<0.05).Conclusion:3.0T HR-MRI has higher efficiency in the assessment for the prognosis of patients with AIS,which can provide guidance for the judgement of prognosis and the formulation of treatment scheme through observes the changes of a series of parameters include T2WI signal strength index,T1WI signal strength index,the lumen area at the narrowest point,plaque enhancement rate.The above parameters are risk factors that affect the prognosis of patients,which often represent the progress of patients'conditions.

Objective:To investigate the clinical application effect of bypass vein bridging in repairing high-voltage electric burn wounds on the head with free anterolateral thigh flaps.Methods:This study was a retrospective observational study. From May 2017 to December 2022, 8 patients with high-voltage electric burns on the head who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 6 males and 2 females, aged 33 to 73 years. All patients had skull exposure, including 3 cases of large skull defect, 1 case of left eye necrosis, and 3 cases of cerebral hemorrhage. After debridement, the head wound area was from 13 cm×7 cm to 21 cm×15 cm, and the free anterolateral thigh flap with the area of 14 cm×8 cm to 22 cm×16 cm was cut for repair. The main descending branch of the lateral circumflex femoral artery carried by the flap was anastomosed end-to-end with the superficial temporal artery in the recipient area. One accompanying vein of the anastomotic artery of the flap was end-to-end anastomosed with the branch of the external jugular vein via great saphenous vein bridging, and the other accompanying vein was end-to-end anastomosed with the superficial temporal vein in the recipient area. The donor site wounds were directly sutured or closed with medium-thickness skin grafts from inner thigh. The blood supply and survival of the flap, and the wound healing on the head were observed after operation. The blood flow and lumen filling of the transplanted vein were observed and recorded by using color ultrasound diagnostic system within 2 weeks after operation. The wound repair method and wound healing of the flap donor site were recorded and observed. Patients were followed up to observe the appearance of the flaps and the flap donor sites, the muscle strength of the lower limbs where the flap donor site was located, and whether the patient could complete standing, walking, and squatting using the lower limbs where the flap donor site was located.Results:The flaps of 8 patients survived after operation, and no arterial or venous crisis occurred. The wounds of 5 patients on the head healed after operation, and the wounds of 3 patients on the head healed after second debridement 21 to 35 days after operation due to exudates under the flap 2 weeks after operation. Within 2 weeks after operation, the grafted vein continued to be unobstructed. After the ultrasound probe was pressurized, the grafted vein could be deflated, and the blood vessels were rapidly filled after the probe was released. The wounds of flap donor sites of 3 patients were directly sutured and healed 2 weeks after operation. The wounds of flap donor sites of 5 patients were closed with medium-thickness skin grafts from inner thigh, and all the skin grafts survived 12 days after operation. During follow-up of 6 to 12 months, the head flaps of all patients were slightly bloated without hair growth. Mild linear or patchy scar hyperplasia was left in the donor site. The muscle strength of the lower limbs where the flap donor site was located was normal and did not decrease. The patients could stand, walk, and squat with the lower limbs where the flap donor site was located.Conclusions:When using the free anterolateral thigh flap to repair high-voltage electric burn wounds of various areas and depths on the head, bypass vein bridging can reduce the occurrence of postoperative flap vein crisis and improve the quality of postoperative wound healing without affecting the function of the lower limbs where the flap donor site is located.

Objective This study is focused on ultrasound multimodality examination,which refers to the combined use of three ultrasound examination modalities,ultrasound(US),acoustic radiation force impulse(ARFI)imaging,and contrast-enhanced ultrasound(CEUS).The purpose of this study is to analyze the value of applying ultrasound multimodality examination in the differential diagnosis of benign and malignant breast non-mass-like lesions(NMLs).Methods Cases of breast NMLs were analyzed retrospectively,and the nature of all the lesions was verified by pathological examination.Based on the gray-scale ultrasound image characteristics,the cases were classified into types Ⅰto Ⅴ,and type Ⅰ and type Ⅱ were further classified into 4 subtypes,Ⅰa,Ⅰ b,Ⅱ a,and Ⅱ b,according to whether there was also calcification,and the proportion of malignant cases in each subtype was statistically analyzed.Logistic regression models of US,US+ARFI,US+CEUS,and US+ARFI+CEUS for the diagnosis of malignant cases were established,ROC curves were drawn,the area under the curve(AUC)was calculated,and comparisons were made accordingly.The detection rate of malignant NMLs without calcification(atypical malignant NMLs)by the combination examination of US,ARFI,and CEUS was analyzed.Results A total of 407 cases were included in the study.All subjects were female,aged 22 to 81 years,with the average age being(47.0±1 1.0)years.There were 220 benign cases and 187 malignant cases.Ranked from the highest to the lowest,the malignancy proportion of the different types wasⅠb＞Ⅱb＞Ⅲ＞V＞Ⅰa＞Ⅱa＞Ⅳ.The malignant proportion of the low echo area with calcification was significantly higher than that of the lesions without calcification.The AUC(95％confidence interval[CI])for diagnosing malignant cases with the logistic regression models of US,US+ARFI,US+CEUS,and US+ARFI+CEUS were 0.895(0.862-0.927),0.908(0.878-0.937),0.921(0.893-0.948),and 0.927(0.902-0.952),respectively.Comparison of the AUC of the 4 regression models showed significant differences(P＜0.001).The detection rate of US for NMLs without calcification was 80.7％.When US was used in combination with ARFI and CEUS,86.4％of the malignant NMLs lesions without calcification could be detected if the lesion CEUS score was 4 or 5 points or if shear-wave velocity(SWV)≥4.28 m/s.Conclusion Breast NMLs with calcification show high risks of malignancy,and a pathological examination is always recommended for a conclusive diagnosis.Ultrasound multimodality examination can improve the diagnostic accuracy of breast NML without calcification.

Objective:To explore the technique and clinical effects of free medial plantar flap on reconstruction of the severe defect of thumb caused by electric burn.Methods:Surgical techniques and clinical effects were explored in reconstruction with free medial plantar flap for treatment of severe electric burns of thumbs. From July 2016 to July 2021, 18 patients suffered from severe electric burns of thumbs were admitted in the Department of Burn, Zhengzhou First People's Hospital. All the wounds were the entrance of electric burns. After thorough debridement, the arteries, nerves, tendons, phalanges and interphalangeal joints were exposed to various degrees. Damaged digital proper palmar arteries were ligated and defected proper palmar digital nerves were marked and further anastomosed with the nerves carried by the flap. Palmaris longus tendon grafts were employed to reconstruct the defects of flexor pollicis longus tendon. Wounds were closed by transfer of free medial plantar flaps, and the flap donor sites were closed by inguinal skin grafts. Survival of the flap was observed 1 week after surgery, and the survival of the skin graft in the foot donor site 12 days after surgery. Outpatient follow-up including observation of the appearance and texture of the flap, evaluation of sensory function, thumb alignment and finger flexion according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. Evaluate the scar hyperplasia in the foot donor site and the standing and walking functions of the donor foot.Results:All flaps survived,at 1 week after surgery. On the 12th day after surgery, all 16 foot flap survived, and 2 patients had local necrosis, and the necrosis healed completely after dressing change for 10 days, the wound healed completely. Among them, 3 patients without tendon transfer experienced a rupture of the flexor pollicis longus tendon at 2 months after surgery, and underwent another palmaris longus tendon transfer. After the surgery, functional exercise was performed with the palm and flexor fingers. After 6-12 months of follow-up, the blood supply, appearance, and texture of the flap were good and similar to that of the palmar skin of the thumb, with varying degrees of recovery in sensation. The TPD was 6-11 mm, and the thumb was restored to varying degrees. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 13 cases in excellent and 5 cases in good. Mild scar hyperplasia remains in the flap site of donor feet, which does not affect the standing and walking functions of the donor foot.Conclusion:The texture of medial plantar skin is similar to that of palmar skin, with good wear resistance and good sensation. Furthermore, it causes a little damage to the donor site and without obvious complication. The medial plantar flap is ideal for reconstruction of a severe wound caused by electric burn in thumb.

Objective:To explore the curative effects of foot microflap free transplantation in the repair of full-thickness electric burn wounds deep to tendon or even bone in fingers.Methods:A retrospective observational study was conducted. From July 2017 to February 2022, 20 patients with full-thickness electric burn wounds deep to tendon or even bone in fingers who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 19 males and 1 female, aged 18 to 64 years. Among the 20 wounds, 15 wounds were located on the palm side, including 8 on the thumb, 5 on the index finger, and 2 on the middle finger; 5 wounds were located on the back, including 1 on the index finger and 4 on the middle finger. After debridement, the wound area ranged from 4.5 cm×2.0 cm to 7.0 cm×3.0 cm. According to the principle of tissue structure similarity, 10 wounds were repaired with plantar medial flaps, 5 wounds were repaired with hallux peroneal flaps, and 5 wounds were repaired with dorsalis pedis artery flaps, with flap area of 5.0 cm×2.5 cm-8.0 cm×3.5 cm. The flaps were transplanted freely and arteries and veins and/or nerves were anastomosed at the same time. The wound in the donor site was repaired with thigh medium-thick skin graft. The survival of flaps and skin grafts were observed after surgery. The appearance of flap, temperature and color of the distal end in the affected finger were observed during follow-up. At the last follow-up, the joint function and flap sensory recovery of the affected finger were evaluated with the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association; the two-point discrimination distance of skin in the area of flaps with nerve anastomosis was measured; the satisfaction of patients with the curative effect was investigated by using the curative effect satisfaction rating scale, and the very satisfied rate was calculated; the repair effect of flap was evaluated by the comprehensive evaluation scale, and the excellent and good rate was calculated.Results:All the flaps and skin grafts survived after surgery. During the follow-up of 10-18 months after surgery, the appearance of flap was natural and not bloated; the temperature and color of the distal end in the affected finger were basically the same as that of normal finger skin. At the last follow-up, the function recovery of the affected finger joints was as follows: 11 affected fingers were within the normal range of motion, 6 affected fingers had their total active range of motion recovered to 85% of the healthy side, and 3 affected fingers had their total active range of motion recovered to 75% of the healthy side; the flap sensory recovery was as follows: the sense of 15 flaps with nerve anastomosis all recovered to grade S3 +, and the two-point discrimination distance of skin in the flap area was 7.0-9.0 mm; the sense of 1 flap without nerve anastomosis recovered to grade S2 and the sense of 4 flaps recovered to grade S1. The satisfaction with curative effect of 20 patients was very satisfied in 16 cases and moderately satisfied in 4 cases, with the very satisfied rate of 80%; the repair result of 20 flaps was excellent in 16 cases, good in 2 cases, and fair in 2 cases, with excellent and good rate of 90%. Conclusions:Due to the similar tissue structure of donor site and recipient site, foot microflap free transplantation in the repair of full-thickness electric burn wounds deep to tendon or even bone in fingers can achieve good appearance and function, with better functional and sensory recovery of the affected finger in the case of nerve anastomosis. Patients have high degree of satisfaction with the curative effects, which is worthy of promotion.

Objective:To explore the effect and involved mechanism of naringenin on acute kidney injury (AKI) induced by ischemia-reperfusion (IR).Methods:The IR-AKI rat model was constructed using the classic bilateral renal pedicle clamping method, then renal function and pathological change were assessed, as well as inflammation-associated genes were detected by quantitative real-time PCR. The hub genes were selected through differential gene analysis and protein-protein interaction network analysis, and their transcription factors were predicted, which constructed a protein library together. The proteins binding to naringenin were selected by reverse molecular docking analysis and further their binding patterns were predicted to explore the mechanism of naringenin. Finally, the results of bioinformatics were verified by experimental methods.Results:Compared with the AKI group, the kidney pathology of the rats in the naringenin pretreatment group was significantly improved, and the renal tubular injury score was reduced ( P<0.01); meanwhile the serum creatinine level and the mRNA expression of the kidney injury molecule 1 (KIM-1) were significantly decreased (both P<0.05). Compared to sham group, IR-AKI increased the level of nuclear factor κB (NF-κB), tumor necrosis factor-α and interleukin-1β (all P<0.05), which reversed by naringenin indicated that naringenin inhibited inflammation in IR-AKI. Differential gene analysis was performed on the GSE98622 data set, and 359 differential genes were obtained. In reverse molecular docking, the proteins with smallest binding energy including NFKBIA, BCL3, NFKB2 and RELA were considered to be related to the preventive effect of naringenin, which were mainly enriched in NF-κB-related inflammation pathways. Domain functional analysis of NF-κB-related genes showed that naringenin could stably bind to its key domain. According to quantitative real-time PCR results, naringenin increased BCL3 level after AKI ( P<0.05), and further decreased the expression level of RELA and NFKB2 (both P<0.05). Conclusion:Naringenin protects IR-AKI by alleviating inflammation, and its mechanism is related to increasing BCL3 and thereby inhibiting the NF-κB pathway.

Abstract Objective　To observe the dynamic changes of hippocampus microstructure in patients with cerebral infarction within the territory of the middle cerebral artery (MCA) with cortex involvement,thus exploring the relationship between these changes and the changes in semantic memory function.Methods　Twenty-two patients with acute subcortical infarction were assessed for cognitive function,structural magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) at 1,4,and 12 weeks (W) respectively.A total of 22 gender and age matched subjects were enrolled as healthy controls.Results　Bilateral hippocampal volume did not change significantly during the entire follow-up period.Spearman’s rank correlations showed that percent decreases in immediate recall and long-delay recall scores correlated negatively with percent increases in mean diffusivity (MD) values in the ipsilateral hippocampus (immediate,rs=0.683,P=0.006; long-delay,rs=-0.602,P=0.013).Conclusion　In patients with cerebral infarction within the territory of the MCA with cortex involvement,the microstructural integrity of the hippocampus may be damaged before the macrostructure changes,and these changes may be related to the decline of semantic memory.
