Neurofibromatosis type 1 (NF1) presents with a diverse range of symptoms that can affect the skin, bones, eyes, central nervous system, and other organs. This article reports the diagnosis and treatment process of a patient with NF1 complicated by bilateral severe-to-profound sensorineural hearing loss. Genetic testing revealed a heterozygous variant of NF1 NM_ 000267.3: c.4054_ 4058del(p.Ser1352LeufsTer20, supporting the diagnosis of NF1. After thorough evaluation, a right cochlear implantation was performed, yielding satisfactory postoperative results. This case suggests that NF1 patients may exhibit phenotypic heterogeneity and atypicality, providing a reference for clinicians in the diagnosis and treatment of such patients.

Objective:To investigate and summarize the chest CT imaging features of patients with novel coronavirus pneumonia (COVID-19), bacterial pneumonia and other viral pneumonia.Methods:Chest CT data of 102 patients with pulmonary infection due to different etiologies were retrospectively analyzed, including 36 patients with COVID-19 admitted to Hainan Provincial People's Hospital and the Second Affiliated Hospital of Hainan Medical University from December 2019 to March 2020, 16 patients with other viral pneumonia admitted to Hainan Provincial People's Hospital from January 2018 to February 2020, and 50 patients with bacterial pneumonia admitted to Haikou Affiliated Hospital of Central South University Xiangya School of Medicine from April 2018 to May 2020. Two senior radiologists and two senior intensive care physicians were participated to evaluated the extent of lesions involvement and imaging features of the first chest CT after the onset of the disease.Results:Bilateral pulmonary lesions were more common in patients with COVID-19 and other viral pneumonia, and the incidence was significantly higher than that of bacterial pneumonia (91.6%, 75.0% vs. 26.0%, P < 0.05). Compared with other viral pneumonia and COVID-19, bacterial pneumonia was mainly characterized by single-lung and multi-lobed lesion (62.0% vs. 18.8%, 5.6%, P < 0.05), accompanied by pleural effusion and lymph node enlargement. The proportion of ground-glass opacity in the lung tissues of patients with COVID-19 was 97.2%, that of patients with other viral pneumonia was 56.2%, and that of patients with bacterial pneumonia was only 2.0% ( P < 0.05). The incidence rate of lung tissue consolidation (25.0%, 12.5%), air bronchial sign (13.9%, 6.2%) and pleural effusion (16.7%, 37.5%) in patients with COVID-19 and other viral pneumonia were significantly lower than those in patients with bacterial pneumonia (62.0%, 32.0%, 60.0%, all P < 0.05), paving stone sign (22.2%, 37.5%), fine mesh sign (38.9%, 31.2%), halo sign(11.1%, 25.0%), ground-glass opacity with interlobular septal thickening (30.6%, 37.5%), bilateral patchy pattern/rope shadow (80.6%, 50.0%) etc. were significantly higher than those of bacterial pneumonia (2.0%, 4.0%, 2.0%, 0%, 22.0%, all P < 0.05). The incidence of local patchy shadow in patients with COVID-19 was only 8.3%, significantly lower than that in patients with other viral pneumonia and bacterial pneumonia (8.3% vs. 68.8%, 50.0%, P < 0.05). There was no significant difference in the incidence of peripheral vascular shadow thickening in patients with COVID-19, other viral pneumonia and bacterial pneumonia (27.8%, 12.5%, 30.0%, P > 0.05). Conclusions:The probability of ground-glass opacity, paving stone and grid shadow in chest CT of patients with COVID-19 was significantly higher than those of bacterial pneumonia, and it was more common in the lower lungs and lateral dorsal segment. In other patients with viral pneumonia, ground-glass opacity was distributed in both upper and lower lungs. Bacterial pneumonia is usually characterized by single lung consolidation, distributed in lobules or large lobes and accompanied by pleural effusion.

Objective:To study the surveillance results of soil-transmitted nematode (STN) disease at the national surveillance site in Nanchang City, so as to scientifically formulate prevention and control strategies for parasitic diseases in Nanchang City.Methods:From 2016 to 2020, in Nanchang County, the national surveillance site of STN disease in Nanchang City, no less than 1 000 fecal samples and 25 soil samples of permanent residents over 3 years of age were investigated annually. The improved Kato-Katz thick smear method was used to detect the eggs of STN in the population, species identification of hookworm was carried out by test-tube filter paper incubation, the Enterobius vermicularis eggs of 3 - 9 years old children were detected by cellophane anal swab method, and the soil samples were used to identify hookworm larvae and of Ascaris lumbricoides eggs. Results:The total infection rate of STN was 0.93% (47/5 054) from 2016 to 2020 in the national surveillance site of Nanchang City. The annual infection rates were 0.10% (1/1 000), 2.94% (30/1 021), 0.79% (8/1 008), 0.50% (5/1 002) and 0.29% (3/1 023), respectively; the infection rates of hookworm, Ascaris lumbricoides and Trichuris trichiura were 0.42% (21/5 054), 0.02% (1/5 054) and 0.49% (25/5 054), respectively. Totally 97.87% (46/47) of the infected persons were mild infection. The population distribution characteristics showed that there was significant difference in STN infection rate among different education levels (χ 2 = 18.06, P = 0.001), but there was no significant difference in infection rate among different sex, age and occupation (χ 2 = 0.92, 2.01, 13.60, P > 0.05). Among them, the infection rate of junior high school cultural was the highest (1.84%, 24/1 301). The culture of hookworm larvae showed that 90.48% (19/21) were Necator americanus; the infection rate of Enterobius vermicularis in 3 - 9 years old children, the contamination rate of soil hookworm larvae and Ascaris lumbricoides eggs, were all 0. Conclusion:STN disease shows a low prevalence trend at the national monitoring site in Nanchang City, Trichuris trichiura and hookworm are the key insect species for STN disease control in Nanchang City in the future.

Objective:To explore the relationship between parental rearing style and mental health of community correction offenders, as well as the mediating role of personality and coping styles in it.Methods:A questionnaire survey was conducted on 385 community correction offenders by the Egma Minnen av Bardndosna uppforstran(EMBU), symptom checklist-90 (SCL-90), NEO five-factor inventory(NEO-FFI) and simplified coping style questionnaire(SCSQ) from February to July 2022.SPSS 27.0 software was used for correlation analysis and regression analysis.AMOS 26.0 was used for the construction of structural equation, and Bootstrap was used for mediating effect analysis.Results:In parental rearing styles, the dimension of parents' severe punishment(19.09±5.32, 12.93±4.77), father's preference for subjects(9.29±3.30), father's excessive protection(10.40±2.19), mother's excessive interference and protection(33.81±6.06)and parents' refusal and denial (9.08±3.03, 12.17±4.25) were significantly positively correlated with the total score of SCL-90 (140.63±44.28)( r=0.114, 0.168, 0.121, 0.144, 0.224, 0.187, 0.220 respectively, all P<0.05). Parents' emotional warmth and understanding, parents' severe punishment and parents' refusal and denial were significantly correlated with coping styles ( r=0.420, 0.420, -0.189, -0.190, -0.174, -0.163 respectively, P<0.05). Neuroticism, extraversion, conformity, rigor in personality were significantly correlated with the total score of SCL-90 ( r=0.542, -0.442, -0.204, -0.202 respectively, P<0.05). Coping style was significantly negatively correlated with the total score of SCL-90 ( r=-0.352, P<0.05). The father's refusal and denial, the mother's emotional warmth and understanding, the mother's excessive interference and protection in the parental rearing styles could predict the mental health of community correction offenders ( β=0.191, -0.163, 0.233 respectively, P<0.05). Coping styles had a negative predictive effect on mental health ( β=-0.352, P<0.05). Neuroticism, preciseness and extra-version in personality could predict mental health ( β=0.461, 0.183, -0.281 respectively, P<0.05). The pathway coefficient of parental rearing styles → mental health was 0.261 ( P<0.001), and the direct effect was significant. The confidence intervals of parental rearing styles → personality traits → mental health path, parental rearing styles → coping tendency → mental health path did not include 0, indicating that partial mediating effect of personality traits and coping tendency were significant. Conclusion:Personality traits and coping styles play a mediating role in the influence of parental rearing style on mental health of community correction offenders.

Objective:To provide more options for preoperative localization diagnosis in patients with primary hyperparathyroidism (PHPT), the diagnostic efficacy of parathyroid 4-dimensional computed tomography (4D-CT) in patients with PHPT was evaluated.Methods:This was a single-center retrospective study including 57 patients with surgical proved PHPT. All of the patients underwent 4D-CT, 99Tc m -sestamibi parathyroid imaging (MIBI), and ultrasonography (US) preoperatively. The reference standard for correct localization was based on operation reports and pathology confirmation. The patients were grouped according to the preoperative serum calcium levels, tumor diameter, or ectopic lesions (yes/no), respectively. The sensitivity, specificity, positive predictive value, negative predictive value and area under the curve (AUC) of 4D-CT, MIBI and US, alone or in combination, were analyzed in total and each subgroup patients. Results:Fifty-seven patients (39 women, 18 men; mean age of 56.5 years) were evaluated, including four cases with multi-gland disease and thirteen cases with ectopic parathyroid lesions. In all the patients, similar diagnostic efficacy was found in 4D-CT (AUC: 0.943) and MIBI (AUC: 0.927), both of which were higher than that of US (AUC: 0.847) ( P = 0.01 for 4D-CT vs. US; P = 0.04 for MIBI vs. US). In a subset analysis for ectopic quadrants, the diagnostic efficacy of 4D-CT was significantly higher than that of MIBI ( P = 0.04) or US ( P = 0.01), with the sensitivity of 100%, 69.2%, and 61.5%, and AUC of 0.989, 0.846, and 0.808 for 4D-CT, MIBI and US, respectively. Conclusions:4D-CT has similar diagnostic efficacy for preoperative localization to MIBI in patients with PHPT, and it is superior to MIBI and US in identifying the ectopic parathyroid gland. 4D-CT can be recommended as an alternative preoperative localization method, especially when parathyroid lesions could not be precisely located by US and MIBI.

Objective: To explore the mediating effect of interpersonal sensitivity between social adaptation and openness, as well as the moderating role of peer attachment among offenders in community. Methods: Totally 155 offenders from 5 communities in Yinchuan city were investigated by symptom self-rating scale, NEO five-factor inventory(NEO-FFI), social adaptability scale and the inventory of parent and peer attachment-revised. Using the macro program PROCESS of SSPS to test the mediating effect of interpersonal sensitivity and the moderating role of peer trust. Results: The scores of interpersonal sensitive subscale of the symptom checklist 90, the openness subscale of NEO five-factor inventory, the inventory of parent and peer attachment-revised were (1.52±0.48), (3.05±0.30), (0.72±0.60) and (83.40±12.17), respectively. Openness, peer attachment were positively correlated with social adaptation (r=0.25, 0.44, P<0.01), and negatively correlated with interpersonal sensitivity (r=-0.18, -0.37, P<0.05). Interpersonal sensitivity was negatively correlated with social adaptation (P<0.01). Peer trust had a significant moderating effect on openness and interpersonal sensitivity (β=0.02, SE=0.01, P<0.05). Interpersonal sensitivity played a mediating role in the relationship between openness and social adaptation (β=-0.38, SE=0.10, P<0.01). In case of high peer trust(β=-0.59, SE=0.19, P<0.001) and mid-level of peer trust(β=-0.28, SE=0.11, P<0.05), there were both significant effect between openness and social adaptation. Conclusion Openness influences the social adaptation though interpersonal sensitivity, while peer trust moderates the effect of openness on social adaptation.

Objective To evaluate the application value of MSCT in preoperative diagnosis and postoperative evaluation in children with cavernous transformation of the portal vein (CTPV).Methods 11 children diagnosed with CTPV by surgery were included in this study in our hospital.All patients underwent both plain and enhanced MSCT scans before surgery,and ultrasound or MSCT scan after surgery.Results In all 11 cases,preoperative CT showed different degrees of splenomegaly and the plain CT showed abnormal soft tissue mass in the hepatic hilar area.Enhanced CT showed stenosis or occlusion of portal vein trunk,earthworm-like blood vessels in the hilar region,and that the left and/or right branch of intrahepatic portal vein were replaced by multiple densely-distributed blood vessels (typeⅡ). Superior mesenteric-intrahepatic left portal shunt (Rex surgery)was performed in all 11 cases with successful results.All patients were followed up for 2-20 months after surgery.Imaging examinations showed anastomotic patency in 9 cases and stenosis in 2 cases.Conclusion MSCT findings of CTPV in children have certain characteristics.MSCT plays an important role in preoperative diagnosis and postoperative evaluation of CTPV in children.

AIM: To study the protective effect of puerarin on the atherosclerosis of RAW264.7-derived foam cells.METHODS: The model of foam cells was established by incubating the RAW264.7 cells with ox-LDL.The choles-terol uptake was evaluated by a DiI-ox-LDL binding assay.The ability of cholesterol efflux of the RAW264.7-derived foam cells was detected by cholesterol efflux assay.The protein levels of LC3II, P62, CD36, ABCA1, LAL and p-AMPK were determined by Western blot.RESULTS: Puerarin treatment reduced the cholesterol uptake capacity and enhanced the cho-lesterol efflux rate.The protein levels of LC3II, ABCA1 and LAL in puerarin group were higher than that in ox-LDL group, while the protein levels of P62 and CD36 were obviously decreased, and those in rapamycin treatment group had the same change as puerarin group.The protein levels of LC3II, ABCA1 and LAL were obviously decreased and the protein level of p-AMPK was increased after co-treated with 3-MA.CONCLUSION: Puerarin promotes LAL and ABCA1-mediated cho-lesterol efflux in ox-LDL-treated RAW264.7 macrophages, which might enhance autophagy through AMPK-dependent path-way for cholesterol efflux regulation, and reduce the uptake of lipids by CD36 negative regulation.

Objective: To study the clinical outcomes of stent-thrombosis (ST) at different times in patients after drug-eluting stent (DES) implantation.
Methods: A total of 131 coronary angiography conifrmed ST patients in our hospital from 2005-01 to 2015-04 were studied. According to the time of ST occurrence, the patients were divided into 2 groups: Early ST group, ST occurred ≤30 days,n=42 and Late ST group, ST occurred >30 days,n=89. The in-hospital and follow-up information was collected; clinical outcomes were compared between 2 groups.
Results: The in-hospital MACE occurrence rate in Early ST group was higher than that in Late ST group (16.7% vs 4.5%),P=0.04. There were 123 patients survived to discharge and they were followed-up for the median of 38.00 (15.00, 62.00) months. Kaplan-Meier analysis estimated that the MACE-free survival was similar between 2 groups (41.9% vs 36.3%), P=0.43.
Conclusion: In-hospital MACE occurrence was higher in early ST patients, while the long term prognosis was similar between the early and late ST patients for whom with DES implantation.

Objective To explore the effects of Chinese herbal compound Tangbikang on the expressions of p38 MAPK of sciatic nerve and plasma TNF-α in diabetic rats. Methods Ten of the sixty male SD rats were selected randomly as normal group, and the rest were fed with high-fat diet and low-dosage STZ was used to induce type Ⅱdiabetic rat models. Model rats were randomly divided into model group, mecobalamine group and Tangbikang low-, medium-, and high-dosage groups, 10 rats in each group. Each medication group was intervened with relevant medicine. Rat unilaterals sciatic nerves were taken after 16 weeks. The content of TNF-α in plasma was determined by radioimmunoassay. Western blot method was used to detect the expressions of p38 and p-p38 MAPK protein of sciatic nerve. Results Compared with normal group, the expressions of p38 and p-p38 protein and content of TNF-αin model group significantly increase (P<0.05, P<0.01). Compared with the model group, the expressions of p-p38 protein and the content of TNF-α significantly decreased after medicine intervention in different doses Tangbikang groups and mecobalamin group (P<0.05, P<0.01). The expression of p38 protein in Tangbikang high-dose group significantly decreased (P<0.05), with statistical significance (P<0.05). Conclusion Tangbikang can reduce the expression of p38 and p-p38 MAPK protein of the rat sciatic nerve, and reduce the content of TNF-α protein in rat plasma, which may be one of the effective targets of neuroprotection and abirritation of diabetic peripheral neuropathy.
