ObjectiveTo investigate the effects of Huanglian Jiedutang （HLJDT） on cognitive function in mice with ischemic stroke （IS） and to elucidate whether its neuroprotective effects are mediated by inhibition of the nuclear factor-κB （NF-κB） signaling pathway and subsequent suppression of NF-κB-regulated neuronal apoptosis. MethodsAn IS model was established using middle cerebral artery occlusion （MCAO）. Sixty C57BL/6J mice were randomly assigned to five groups （n =12 per group）， i.e.， sham operation， model， HLJDT low-dose （3.9 g·kg^-1·d^-1）， HLJDT high-dose （7.8 g·kg^-1·d^-1）， and Ginkgo biloba extract （GBE， 31.2 mg·kg^-1·d^-1）. Post-operatively， neurological deficit scores （Longa score）， cerebral infarct volume assessed by 2，3，5-triphenyltetrazolium chloride （TTC） staining， and brain water content were evaluated. Learning and memory were assessed using new object recognition （NOR） and fear conditioning （FC） tests. Hippocampal pathology was examined via hematoxylin and eosin （HE） staining. Immunofluorescence detected expression of glial fibrillary acidic protein （GFAP， astrocyte marker）， cellular oncogene Fos （c-Fos， neuronal activation marker）， and glutamate decarboxylase 65 （GAD65）. Western blot measured nuclear factor-κB inhibitor protein α （IκBα）， phosphorylated IκBα （p-IκBα）， NF-κB p65， phosphorylated NF-κB p65 （p-NF-κB p65）， ionic calcium binding adapter molecule 1 （Iba-1）， tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and apoptosis-related proteins， such as cleaved cysteinyl aspartate-specific protease 3 （Caspase-3）， B-cell lymphoma 2 （Bcl-2）， and Bcl-2-associated X protein （Bax）. Real-time quantitative PCR （Real-time PCR） was used to assess mRNA levels of Iba-1， TNF-α， IL-1β， NF-κB p65， cleaved Caspase-3， Bax， and Bcl-2. ResultsCompared with the sham group， the model group exhibited significantly increased neurological deficit scores， brain water content， and cerebral infarct volume （P<0.01）. Hippocampal CA1 neurons were disorganized， showing nuclear pyknosis and karyolysis. NOR exploration time and FC freezing time were significantly reduced （P<0.01）. GFAP and c-Fos expression were increased， while GAD65 expression was decreased （P<0.01）. Cleaved Caspase-3 and Bax were upregulated， Bcl-2 was downregulated， and the Bax/Bcl-2 ratio was elevated （P<0.01）. Expression levels of p-IκBα， p-NF-κB p65， IL-1β， TNF-α， and Iba-1 were significantly increased （P<0.01）. Compared with the model group， HLJDT high-dose， low-dose， and GBE groups showed significant improvements in all parameters （P<0.01）. Among them， the HLJDT high-dose group showed the most pronounced neuronal structural recovery and superior performance in NOR and FC tests （P<0.01）. In this group， GFAP and c-Fos decreased， GAD65 increased （P<0.01）， apoptosis-related protein expression was reversed， and NF-κB signaling and related inflammatory factor expression were suppressed （P<0.01）. ConclusionHLJDT ameliorates cognitive dysfunction in mice after IS， potentially by inhibiting the NF-κB signaling pathway， thereby reducing neuroinflammation and hippocampal neuronal apoptosis.

OBJECTIVE: To investigate the effectiveness of using 3 hollow compression screws combined with 1 screw off-axis fixation under the guidance of three-dimensional (3D) printed guide plate with mortise-tenon joint structure (mortise-tenon joint plate) for the treatment of Pauwels type Ⅲ femoral neck fractures. METHODS: A clinical data of 78 patients with Pauwels type Ⅲ femoral neck fractures, who were admitted between August 2022 and August 2023 and met the selection criteria, was retrospectively analyzed. The operations were assisted with mortise-tenon joint plates in 26 cases (mortise-tenon joint plate group) and traditional guide plates in 28 cases (traditional plate group), and without guide plates in 24 cases (control group). There was no significant difference in the baseline data of gender, age, body mass index, cause of injury, and fracture side between groups ( P>0.05). The operation time, intraoperative blood loss, frequency of intraoperative fluoroscopy, incision length, incidence of postoperative deep vein thrombosis of lower extremity, pain visual analogue scale (VAS) score at 1 week after operation, and Harris score of hip joint at 3 months after operation were recorded and compared. X-ray re-examination was taken to check the quality of fracture reduction, fracture healing, and the shortening length of the femoral neck at 3 months after operation, and the incidences of internal fixation failure and osteonecrosis of the femoral head during operation. RESULTS: Compared with the control group, the operation time, intraoperative blood loss, and frequency of intraoperative fluoroscopy reduced in the two plate groups, and the quality of fracture reduction was better, but the incision was longer, and the differences were significant ( P<0.05). The operation time and intraoperative blood loss were significantly higher in the traditional plate group than in the mortise-tenon joint plate group ( P<0.05), the incision was significantly longer ( P<0.05); and the difference in fracture reduction quality and the frequency of intraoperative fluoroscopy was not significant between two plate groups ( P>0.05). There was 1 case of deep vein thrombosis of lower extremity in the traditional plate group and 1 case in the control group, while there was no thrombosis in the mortise-tenon joint plate group. There was no significant difference in the incidence between groups ( P>0.05). All patients were followed up 12-15 months (mean, 13 months). There was no significant difference in VAS score at 1 week and Harris score at 3 months between groups ( P>0.05). Compared with the control group, the fracture healing time and the length of femoral neck shortening at 3 months after operation were significantly shorter in the two plate groups ( P<0.05). There was no significant difference between the two plate groups ( P>0.05). There was no significant difference in the incidences of non-union fractures, osteonecrosis of the femoral head, or internal fixation failure between groups ( P>0.05). CONCLUSION For Pauwels type Ⅲ femoral neck fractures, the use of 3D printed guide plate assisted reduction and fixation can shorten the fracture healing time, reduce the incidence of postoperative complications, and be more conducive to the early functional exercise of the affected limb. Compared with the traditional guide plate, the mortise-tenon joint plate can reduce the intraoperative bleeding and shorten the operation time.

Objective:To explore the spectrum of genetic variants and phenotypes of Phenylalanine hydroxylase deficiency (PAHD) in Lianyungang area and the correlation between genotype and phenotypes among the patients.Methods:Eighty children with Hyperphenylalaninemia (HPA) diagnosed at the Lianyungang Branch of Jiangsu Provincial Newborn Screening Center between January 2015 and December 2022 were enrolled. Peripheral blood samples were collected for genetic analysis using next generation sequencing (NGS), Sanger sequencing, and multiplex ligation-dependent probe amplification (MLPA) to identify the variants of PAH gene. Clinical and phenotypic data were concurrently analyzed to investigate the correlation between the types of PAH gene variant and phenotypes. This study was approved by the Medical Ethics Committee of Lianyungang Maternal and Child Health Care Hospital (Ethics No.: XM2022041). Results:① PAH variants were identified in 93.75% (75/80) of the children, classified as PAHD cases, while 6.25% (5/80) harbored PTS variants. ② Of the 150 PAH alleles from 75 PAHD children, a total of 152 variants (55 distinct types) were detected, with a detection rate of 100%. 80.26% (122/152) were located in exons, with the main types of variants were missense variants (67.11%, 102/152). 53.29% (81/152) of coding sequence variants occurred in the PAH gene catalytic center region of PAH protein, while 19.74% (30/152) of variants involved non-coding sequences. ③The phenotypes of the 75 PAHD children were evenly distributed. The rescreening Phe concentrations and Phe/Tyr ratios of classic-phenylketonuria (CPKU) and mild-phenylketonuria (MPKU) patients were markedly higher than initial screening values ( P<0.001, P<0.001; P=0.004, P=0.016). The genotypes of the PAHD patients mostly occurred as compound heterozygotes, and different mutation positions and variant types significantly affect the phenotype ( P=0.042, P=0.045). ④APV/GPV genotype-phenotype analysis of 61 patients showed high consistency between predicted and actual phenotypes ( κ=0.755, P<0.001). Conclusion:PAH variants were detected in the most of HPA children in Lianyungang area. The location and type of PAH variants were related to the severity of the phenotype, and the non-coding sequence variants and non-missense variants may aggravate the phenotype, and the APV/GPV model predicted the phenotype was highly consistent with the actual phenotype.

Objective:To evaluate the correlation between inflammatory diet and reflux esophagitis (RE) with the dietary inflammatory index (DII), and to provide scientific evidence for the prevention and treatment of RE at the level of dietary guidance.Methods:From December 2021 to September 2022, 145 RE patients (RE group) who visited the First Affiliated Hospital of Xinjiang Medical University were recruited. During the same period, 145 subjects who underwent check-ups at the First Affiliated Hospital of Xinjiang Medical University were selected as the healthy control group, and age and gender were matched according to the ratio of 1 to 1. The baseline data of the 2 groups, including body mass index, the history of smoking and drinking, poor dietary habits, and physical activity intensity were collected. Dietary intake of the patients was assessed by a semi-quantitative food frequency questionnaire, and the overall DII was calculated to evaluate the potential anti-inflammatory or pro-inflammatory effects of diet. According to the tertiles of the DII of the healthy control group (33.3% and 66.7% as the cut-off), dietary inflammatory potential was divided into low (<-0.06), moderate (-0.06 to 1.11) and high pro-inflammatory potential diet (>1.11). Logistic regression model was performed to analyze the correlation between DII and RE risk. Linear trend test was used to compare the overall change trend of RE risk OR value along with the increase of DII. Independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Results:The body mass index of RE group was higher than that of healthy control group( (24.11±2.57) kg/m 2 vs. (23.38 ±2.60) kg/m 2), and the difference was statistically significant ( t=-2.41, P=0.017). The proportions of smoking, drinking, over-eating, and eating within 3 h before bedtime of RE group was higher than those of the healthy control group (42.8%, 62/145 vs. 31.0%, 45/145; 31.0%, 45/145 vs. 16.6%, 24/145; 33.1%, 48/145 vs. 17.9%, 26/145; 52.4%, 76/145 vs. 13.1%, 19/145), and the differences were statistically significant ( χ2=4.28, 8.39, 8.78 and 50.86, P=0.039, 0.004, 0.003 and<0.001). While the proportions of night snacking and moderate to severe physical activity of RE group were lower than those of the healthy control group (14.5%, 21/145 vs. 24.1%, 35/145; 22.8%, 33/145 vs.37.2%, 54/145), and the differences were statistically significant ( χ2=4.34 and 7.24, P=0.037 and 0.007). The DII of RE group was higher than that of the healthy control group (1.05 (0.03, 1.62) vs. 0.34(-0.61, 1.35)), and the difference was statistically significant ( Z=8 661.50, P=0.010). Compared with the low pro-inflammatory potential diet, high pro-inflammatory potential diet had a 1.30-fold increased the risk of RE ( OR=2.30, 95% confidence interval (95% CI) 1.29 to 4.09, P=0.005). After adjusting for total energy intake, age, gender, ethnicity, body mass index, education level, and physical activity intensity, the high pro-inflammatory potential diet was still positively correlated with the risk of RE ( OR=2.58, 95% CI 1.16 to 5.76, P=0.020). In the continuous DII, the risk of RE increased by 36% for each 1 increase in DII ( OR=1.36, 95% CI 1.11 to 1.68, P=0.003). After adjusting for major confounding factors, the continuous DII was still positively correlated with the risk of RE ( OR=1.41, 95% CI 1.08 to 1.85, P=0.012; OR=1.42, 95% CI 1.05 to 1.93, P=0.023). The results of trend test showed that the higher the DII, the greater the risk of RE ( P=0.039). Conclusions:Pro-inflammatory diet is correlated with the increased risk of RE, and there is a certain dose-response relationship. Reasonable reduction of the intake of pro-inflammatory food may be beneficial to reduce the risk of RE.
