[Analysis of the association of CYP450 gene polymorphisms with ischemic stroke].

OBJECTIVE: To assess the association of cytochrome P450 (CYP450) gene polymorphisms with the occurrence of ischemic stroke (IS). METHODS: From January 2020 to August 2022, 390 IS patients treated at the Zhengzhou Seventh People's Hospital were enrolled as the study group, and 410 healthy individuals undergoing physical examination during the same period were enrolled as the control group. Clinical data of all subjects were collected, which included age, sex, body mass index (BMI), smoking history and results of laboratory tests. Chi-square test and independent sample t test were used for comparing the clinical data. Multivariate logistic regression analysis was used to analyze the non-hereditary independent risk factors for IS. Fasting blood samples of the subjects were collected, and the genotypes of rs4244285, rs4986893, rs12248560 of the CYP2C19 gene and rs776746 of the CYP3A5 gene were determined by Sanger sequencing. The frequency of each genotype was calculated by using SNPStats online software. The association between the genotype and IS under the dominant, recessive and additive models was analyzed. RESULTS: The levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-C), apolipoprotein B (Apo-B) and homocysteine (Hcy) of the case group were significantly higher than those of the control group, whilst the levels of high density lipoprotein (HDL-C) and Apo-A1 (APO-A1) were significantly lower (P < 0.05). Multivariate Logistic regression analysis showed that TC (95%CI = 1.13-1.92, P = 0.02), LD-C (95%CI = 1.03-2.25, P = 0.03), Apo-A1 (95%CI = 1.05-2.08, P = 0.04), Apo-B (95%CI = 1.7-4.22, P < 0.01) and Hcy (95%CI = 1.12-1.83, P = 0.04) were non-genetic independent risk factors for the occurrence of IS. Analysis of the association between the genetic polymorphisms and the risk of IS showed that the AA genotype at rs4244285 of the CYP2C19 gene, the AG genotype and A allele at rs4986893 of the CYP2C19 gene, and the GG genotype and G allele at rs776746 of the CYP3A5 gene were significantly associated with IS. Under the recessive/additive model, dominant model and dominant/additive model, polymorphisms of the rs4244285, rs4986893 and rs776746 loci were also significantly associated with the IS. CONCLUSION: TC, LDL-C, Apo-A1, Apo-B and Hcy can all affect the occurrence of IS, and CYP2C19 and CYP3A5 gene polymorphisms are closely associated with the IS. Above finding has confirmed that the CYP450 gene polymorphisms can increase the risk of IS, which may provide a reference for the clinical diagnosis.

Comparison of the diagnostic value of virtual touch tissue quantification and virtual touch tissue imaging quantification in infants with biliary atresia.

OBJECTIVE: This study aimed to compare the diagnostic performance of vital touch tissue quantification (VTQ) and virtual touch tissue imaging quantification (VTIQ) in diagnosing infants with biliary atresia (BA) from jaundiced infants. METHODS: In this study, 26 jaundiced infants with BA, 33 jaundiced infants without BA, and 40 normal infants were enrolled. The hepatic shear wave velocity (SWV) of each infant was determined by VTQ and VTIQ examinations, respectively. Then, the receiver operating characteristic (ROC) curves were drawn and the area under the curve (AUC) and optimal cut-off values were calculated to evaluate the sensitivities and specificities of VTIQ and VTQ for BA. RESULTS: The mean values of SWV of the control group measured by VTQ and VTIQ were (1.09 ± 0.18) m/s and (1.36 ± 0.21) m/s, respectively. The mean values of SWV of the non-BA group measured by VTQ and VTIQ were (1.30 ± 0.28) m/s and (1.52 ± 0.29) m/s, respectively. The mean values of SWV of the BA group measured by VTQ and VTIQ were (2.36 ± 0.36) m/s and (2.43 ± 0.29) m/s, respectively. The diagnostic threshold of VTQ and VTIQ to diagnose BA was 1.77 and 1.92 m/s. The sensitivities of VTQ and VTIQ to diagnose BA were 90.9% and 95.5%. The specificities of VTQ and VTIQ to diagnose BA were 68.4% and 78.9%. CONCLUSION: Vital touch tissue quantification and VTIQ could help distinguish infants with BA from jaundiced infants by measuring the liver SWV values. VTIQ has higher sensitivity and specificity than VTQ.

Ketogenic diet and growth in Chinese infants with refractory epilepsy.

BACKGROUND AND OBJECTIVES: This study evaluated the impact of 12 months of ketogenic dietary treatment (KDT) on growth in Chinese infants with refractory epilepsy. METHODS AND STUDY DESIGN: The KDT group included patients who were divided into groups A (age 6-12 months), B (12-24 months) and C (24-36 months). The normal group included infants aged approximately 6-12 months, 12-24 months and 24-36 months who were classified into groups A1, B1 and C1, respectively. Data on height, weight, aspartate transaminase (AST), alanine transaminase (ALT), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), zinc, iron, calcium, magnesium, and haemoglobin (Hb) were extracted from the medical records. Then, we compared the impacts of 12 months of KDT on growth. RESULTS: Forty-one patients were included in the KDT group, and 90 infants were included in the normal group. The overall prevalence of underweight (WAZ <-2 SD), stunting (HAZ <-2 SD), wasting (BAZ <-2 SD), and overweight/obesity (BAZ ≥2 SD) were relatively lower in the A and B groups. The prevalence of anaemia in group A was significantly higher than that in group A1. No significant differences were observed in the KDT groups with regard to HDL, LDL, AST, ALT, iron, calcium, magnesium, or zinc. A greater than 50% reduction in weekly seizure frequency was evident in 100% of group A, 78.6% of group B and 77.8% of group C. CONCLUSIONS: The results revealed that patients less than 2 years old who received KDT maintained appropriate growth at the 12-month follow-up.

Procedural fairness predicts cooperative behaviour for high-self-esteem individuals but not for low-self-esteem individuals.

Cooperation is vital for modern society. Previous studies showed that procedural fairness promotes cooperation; however, they mainly focused on cooperation intention, which may fail to reveal actual cooperative behaviour. Moreover, little is known regarding the personality boundary of the effect of procedural fairness on cooperation. Guided by previous findings that self-esteem increases sensitivity to procedural unfairness, we attempted to explore the moderating effect of self-esteem on the association between procedural fairness and cooperative behaviour. In Experiment 1, 160 participants' self-esteem was measured using the Rosenberg Self-Esteem Scale; procedural fairness was manipulated in two conditions, depending on whether money was allocated in an economic game by rolling the dice twice or an allocator's arbitrary choice. Cooperative behaviour was assessed using the chicken game paradigm. Experiment 2 (148 participants) aimed to replicate and extend the results of Experiment 1 using a more rigorous experimental design, in which the possible effect of outcome favourability was excluded. The results of both experiments consistently showed that procedural fairness positively predicted cooperative behaviour, and this association was significant in high-self-esteem individuals, but not in low-self-esteem individuals. These findings shed light on the vital role of self-esteem in understanding the relationship between procedural fairness and cooperative behaviour.

A case report of Noonan syndrome-like disorder with loose anagen hair 2 treated with recombinant human growth hormone.

Protein phosphatase 1 catalytic subunit beta (PPP1CB) is a disease-causing gene of Noonan-like syndrome, which acts via the RAS/MAPK pathway. To date, only 17 patients diagnosed with PPP1CB-related Noonan-like syndrome have been reported around the world, with few reports in Asia. Twelve reported patients are of short stature and only one patient was treated with growth hormone (GH); however, follow-up data is lacking. To the best of our knowledge, this is the first reported patient with complete recombinant human growth hormone (rhGH) treatment follow-up data; the patient has a de novo c.146C>G (p.Pro49Arg) mutation in the PPP1CB gene. The hair pattern of the patient (coarse, curly, slow growing, and fragile) combined with Noonan dysmorphic features, developmental delay, and congenital heart disease, are highly consistent with the typical features observed in Noonan syndrome-like disorder with loose anagen hair 2 (NSLH2). rhGH treatment, administered for 3 years and 8 months, promoted the patient's linear growth. Our findings expand the data regarding the treatment of short stature in patients with NSLH2 caused by PPP1CB mutation. Clinical manifestation, growth and development process, and rhGH therapy effect data will aid in future revision of the relevant diagnosis and treatment guidelines.

Long-term impact of fistula status on growth and anemia in infants with congenital anorectal malformations.

BACKGROUND AND OBJECTIVES: To evaluate the impacts of fistula status over 12 months on growth and development and anemia in infants with anorectal malformation (ARM) and to analyze the effects of comorbidities. METHODS AND STUDY DESIGN: The ARM group included infants who suffered from ARM and underwent three operations including colostomy, anoplasty (group A) and fistula closure (group B). The normal group included infants aged approximately 6 months and 12 months who were classified as groups C and D. A 24-h dietary recall questionnaire was completed by the guardians of all the participants. Data on height, weight, hemoglobin (Hb) level and comorbidities were extracted from electronic medical records. Then, we compared the impacts of the 12-month fistula status on growth and development and anemia among the infants. RESULTS: In total, 47 patients in the ARM group and 100 infants in the normal group were included. The height-for-age z-score (HAZ) was lower in group A than in group B. Compared with those in group D, weight, height, the HAZ and the weight-forage z-score (WAZ) were lower in group B. The incidence of anemia was higher in the ARM group than in the normal group. CONCLUSIONS: Patients with ARM are at risk for growth problems and anemia. The long-term impacts of fistula status on infant length presented earlier than those associated with other physical indicators. Compared to infants with urogenital comorbidities, those with congenital heart disease (CHD) seemed to be more prone to growth disorders and anemia.

Attachment style predicts cooperation in intuitive but not deliberative response in one-shot public goods game.

Cooperation is an important prosocial behaviour that is of great significance to individuals and society. The social heuristics hypothesis (SHH) systematically explains how cooperation is interactively affected by intuitive and deliberative processes. On the one hand, the intuitive process can be either cooperative or selfish, which is determined by previous experience. On the other hand, the deliberative process could support either a cooperative decision or a selfish decision, depending on which strategy could maximise the current payoff. This research aims to investigate the mechanism of cooperation. Attachment style was selected as a proxy for previous experience to examine whether and how previous life experience shapes intuitive response. Time constraint (Studies 1 and 2) and cognitive load (Study 3) were manipulated to dissociate the intuitive and deliberative processes. In addition, cooperation was assessed by adopting one-shot public goods games. Results showed that attachment avoidance (Studies 1, 2, and 3) and attachment anxiety (Study 3) significantly predicted cooperation in the intuition condition, whereas these associations were insignificant in the deliberation condition (Studies 1, 2, and 3). These findings provide further support for the SHH and shed new light on the mechanism of cooperation.

A risk factor for early wheezing in infants: rapid weight gain.

BACKGROUND: The aim of this study was to investigate the correlation between rapid weight gain and early wheezing. METHODS: This study screened 701 infants with lower respiratory tract infection who were no more than 4 months from Jan 1st to Dec 31st in 2018. According to weight-for-age Z-value (WAZ), these infants were divided into the considerably slow weight gain group (group I), the normal weight gain group (group II) and the excessively rapid weight gain group (group III), respectively. The clinical characteristics, weight growth speeds and serum lipid levels were analyzed, and multivariable Logistic model was conducted to select significant variables. RESULTS: Our results showed that male (OR = 1.841, 95%CI: 1.233-2.751), family wheezing (OR = 5.118, 95%CI: 2.118-12.365), age (OR = 1.273, 95%CI: 1.155-1.403), eczema (OR = 2.769, 95%CI: 1.793-4.275), respiratory syncytial virus (RSV) infection (OR = 1.790, 95%CI: 1.230-2.604), birth weight (OR = 1.746, 95%CI: 1.110-2.746) and total cholesterol (TC) (OR = 1.027, 95%CI: 1.019-1.036) and ΔWAZ (OR = 1.182, 95%CI: 1.022-1.368) were associated with early wheezing. Results indicated that serum TC (P = 0.018) and ΔWAZ (P = 0.023) were positive correlation with wheezing days. CONCLUSION: Besides male, family wheezing, age, eczema, RSV infection, birth weight and TC, the rapid weight growth as a risk factor should be concerned in the early wheezing infants.

A dissecting aneurysm of interventricular septum resulting from congenital coronary artery fistula.

RATIONALE: Ventricular septal dissecting aneurysms are rarely caused by congenital coronary artery fistulas. PATIENT CONCERNS: We present a rare case of ventricular septal dissecting aneurysm that resulted from a congenital coronary artery fistula in a 41-year-old female patient with the complaint of chest pain. DIAGNOSIS: Ventricular septal dissecting aneurysm resulting from a right coronary artery fistula. INTERVENTIONS: The patient was advised to receive transcatheter interventional therapy in the department of cardiology. OUTCOMES: It was difficult for the cardiac catheter to reach the orifice of fistula due to the long and circuitous nature of the right coronary artery, which ultimately resulted in abandoning interventional fistula occlusion therapy. The patient finally decided to undergo surgical treatment in Shanghai and the symptoms have been markedly improved after hemodynamic correction. LESSONS: The right coronary artery was the dominant vessel and the fistula was located in the distal part of the posterior descending branch of right coronary artery. Hence, transcatheter closure was appropriate; however, due to the fact that right coronary artery was too long and circuitous, the length of cardiac catheter was relatively insufficient. For this reason, a comprehensive and careful assessment before the operation is necessary.

Features of lymph node metastasis of papillary thyroid carcinoma in ultrasonography and CT and the significance of their combination in the diagnosis and prognosis of lymph node metastasis.

PURPOSE: To investigate the characteristics of lymph node (LN) metastasis of papillary thyroid carcinoma (PTC) with ultrasonography (US) and spiral computed tomography (CT) and the significance of their combination in the diagnosis and prognosis of LN metastasis. METHODS: A total of 93 PTC patients admitted to and treated in the oncology department of our hospital were randomly enrolled in this study. LN imaging signs were explored by US, CT and their combination. Through the comparison with pathological findings, the diagnostic efficiency of three methods in LN metastasis in patients with PTC was analyzed. Postoperatively, all patients were followed up for 1-3 years to analyze the relationship between LN metastasis and the prognosis of PTC. RESULTS: Among 93 PTC patients, 69 (74.19%) had LN metastasis, and 24 (25.81%) had not. US examination revealed that metastatic LN were hypoechoic and obviously calcified, and had aspect ratio >1 and strong blood flow signals. Among them, there were significant differences in calcification and blood flow between LN metastasis group and non-metastasis group (p<0.05). CT images indicated that metastatic LN were swollen, had low-density and were calcified with abundant blood flow signals. In addition, the edge, calcification and CT reinforced examination showed obvious differences between the LN metastasis group and the non-metastasis group (p<0.05). The sensitivity, specificity and accuracy of US alone in the diagnosis of LN metastasis were clearly better than those of CT alone (p<0.05), while their combination was better than both US and CT alone in the sensitivity, specificity and accuracy in the diagnosis of LN metastasis (p<0.05). Follow-up data suggested that the 3-year recurrence or metastasis rates of patients in the metastasis and non-metastasis groups were 4.54 and 11.27%, respectively, showing a statistically significant difference (p<0.05). CONCLUSIONS: US combined with CT can make up for the deficiencies of each examination alone, and improve the sensitivity and specificity of PTC LN metastasis detection. It is worthy of clinical promotion.

Sampled-data-based consensus and containment control of multiple harmonic oscillators: A motion-planning approach.

This paper studies the distributed consensus and containment problems for a group of harmonic oscillators with a directed communication topology. First, for consensus without a leader, a class of distributed consensus protocols is designed by using motion planning and Pontryagin's principle. The proposed protocol only requires relative information measurements at the sampling instants, without requiring information exchange over the sampled interval. By using stability theory and the properties of stochastic matrices, it is proved that the distributed consensus problem can be solved in the motion planning framework. Second, for the case with multiple leaders, a class of distributed containment protocols is developed for followers such that their positions and velocities can ultimately converge to the convex hull formed by those of the leaders. Compared with the existing consensus algorithms, a remarkable advantage of the proposed sampled-data-based protocols is that the sampling periods, communication topologies and control gains are all decoupled and can be separately designed, which relaxes many restrictions in controllers design. Finally, some numerical examples are given to illustrate the effectiveness of the analytical results.

Resource availability hypothesis: Perceived financial and caloric status affect individuals' height preferences for potential partners.

Height is an important concern in human mate choices. Prior research indicates that people who live in areas with abundant resources differ from those who live in areas with scarce resources regarding height preferences. Based on a health-maximizing principle, we propose a resource availability account for such differences. Compared with women's height preferences, men's height preferences are hypothesized to be more dependent on either financial or caloric resource availability. Specifically, taller females would be more preferred by males who are poor in resources than those who are rich in resources. Results from three studies supported these hypotheses. In Study 1, men from remote areas of China who had lower family income preferred taller women more than those from eastern China who had higher family income. In Study 2, men who were financially dissatisfied preferred taller women more than those who were financially satisfied. In Study 3, men with low caloric status preferred taller women more than men with high caloric status. In addition, women's height preferences in Studies 1, 2 and 3 were less determined by resource availability. These findings suggest that height preferences are changeable, depending on financial or caloric status.

[Effect of Paidu Baoshen Pill on renal fibrosis in 5/6 nephrectomized rats].

OBJECTIVE: To observe the anti-renal fibrosis effect of Paidu Baoshen Pill (PBP) on 5/6 nephrectomized rats and to explore its mechanism. METHODS: Totally 50 SD male healthy rats were randomly divided into the normal control group (n = 10), the sham-operation group (n = 10), and the nephrectomy model group (n = 30) according to the proportion of 1:1:3. Rats in the sham-operation group had their renal capsule isolated without nephrectomy. Rats in the nephrectomy model group had their kidneys 5/6 nephrectomized. Then 24 h urine was collected and 24 h urinary protein (24 h UP) detected. Serum blood urea nitrogen (BUN) and serum creatitine (SCr) were also tested. According to the SCr level 30 rats of the model group were further randomly divided into the model group, the PBP group, and the Niaoduqing Granule (NG) group, 10 in each group. Rats in the PBP group and the NG group were respectively administered with PBP (at the daily dose of 1.0 g/kg) and NG (at the daily dose of 3.33 g/kg) by gastrogavage (they were dissolved in distilled water). At the same time, 2 mL distilled water was administered by gastrogavage to rats in the normal control group, the sham-operation group, and the nephrectomy model group, once daily for 4 successive weeks. Mental conditions, activities, hair color, shape of stool, and the body weight were observed during administration. After 4 weeks, urine was collected to detect 24 h UP. Blood was sampled to detect SCr, BUN, transforming growth factor ß1 (TGF-ß1), type III procollagen (PC III), collagen type IV (Col IV), laminin (LN), and fibronectin (FN). After rats were killed, their left remnant renal tissues were collected for pathological examinations. The protein expression quantity of TGF-ß1 and FN was detected by immunohistochemical method. mRNA expression levels of TGF-ß1 and FN were detected using real time fluorescent quantitative PCR. RESULTS: There was no statistical difference in the above indices between the normal control group and the sham-operation group (P > 0.05). Compared with the sham-operation group, rats' general condition was poorer in the model group, their body weight grew slower, and 24 h UP increased; serum levels of BUN, SCr, TGF-ß1, PC III, Col IV, LN, and FN increased; the residual renal pathological lesion was serious; expression levels of TGF-ß1, TGF-ß1, mRNA, FN, and FN mRNA increased in the renal tissue (all P < 0.01). Compared with the model group, rats' general condition was better, their body weight grew faster, 24 h UP reduced (P < 0.05), blood levels of BUN and SCr decreased significantly (P < 0.01), serum levels of TGF-ß1, PC III, CoL IV, LN, and FN decreased (P < 0.05, P < 0.01); the residual renal pathological lesion was attenuated in the PBP group and the NG group; expression levels of TGF-ß1, TGF-ß1, mRNA, FN, and FN mRNA decreased (P < 0.01). Compared with the NG group, blood levels of SCr and FN, and expression levels of FN and FN mRNA decreased more in the PBP group (P < 0.05). CONCLUSIONS: PBP had the effect of anti-renal fibro- sis in 5/6 nephrectomized rats. Down-regulating expression levels of TGF-ß1, and FN from gene transcription and protein translation levels might be one of its mechanisms.

A new Mach-Zehnder interference temperature measuring sensor based on silica-based chip.

A new type of silicon-based Mach-Zehnder interference (MZI) temperature sensor chip with "mosquito coil" structure was designed. The sensor chip used a new MZI interference structure. After the light entered the chip, it split and interfered in the combiner of the chip. The change in the surrounding temperature will cause the refractive index of the waveguide to change, which will cause the output light intensity to change. The sensor used a frequency stabilized laser that was based on a Bragg grating fiber. The experimental results showed that this structure could achieve a resolution of 0.002 °C and measuring range of 30 °C.

Investigation of epidemiological and clinical characteristics of people infected with SARS-CoV-2 during the second pandemic of COVID-19 in Chengdu, China.

Objective: This study investigated the epidemiological and clinical characteristics of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infected patients during the second pandemic of COVID-19 (coronavirus disease of 2019) in Chengdu, China. Furthermore, the differences between first infection and re-infection cases were also compared and analyzed to provide evidence for better prevention and control of SARS-CoV-2 re-infection. Methods: An anonymous questionnaire survey was conducted using an online platform (wjx.cn) between May 20, 2023 to September 12, 2023. Results: This investigation included 62.94% females and 32.97% of them were 18-30 years old. Furthermore, 7.19-17.18% of the participants either did not receive vaccination at all or only received full vaccination, respectively. Moreover, 577 (57.64%) participants were exposed to cluster infection. The clinical manifestations of these patients were mainly mild to moderate; 78.18% of participants had a fever for 1-3 days, while 37.84% indicated a full course of disease for 4-6 days. In addition, 40.66% of the participants had re-infection and 72.97% indicated their first infection approximately five months before. The clinical symptoms of the first SARS-CoV-2 infection were moderate to severe, while re-infection indicated mild to moderate symptoms (the severity of symptoms other than diarrhea and conjunctival congestion had statistically significant differences) (p < 0.05). Moreover, 70.53 and 59.21% of first and re-infection cases had fever durations of 3-5 and 0-2 days, respectively. Whereas 47.91 and 46.40% of first and re-infection cases had a disease course of 7-9 and 4-6 days. Conclusion: The SARS-CoV-2 infected individuals in Chengdu, China, during the second pandemic of COVID-19 had mild clinical symptoms and a short course of disease. Furthermore, compared with the first infection, re-infection cases had mild symptoms, low incidences of complications, short fever duration, and course of disease.

A case report of diagnosis of cat-scratch disease using metagenomic next-generation sequencing.

Cat-scratch disease (CSD) is an anthropozoonotic infection caused by Bartonella henselae, and it is one of the most common causes of lymph node infections in children and adolescents. B. henselae, belonging to the genus Bartonella, is a common human pathogen of human beings. CSD commonly develops as a result of cat scratches and bites or when injured skin comes into contact with cat saliva. The manifestation of CSD clinically differs for each patient based on their immune system. Individuals who have healthy immune systems generally manifest minimal clinical symptoms and do not necessitate any form of treatment. However, patients who have hypo-immunity require prompt medical attention due to the potential manifestation of severe symptoms that affect multiple systems of the body. Long latency and atypical clinical manifestations are characteristics of CSD. Bartonella isolation and identification are challenging procedures that require specialized equipment. There is no gold standard method for CSD diagnosis, and misdiagnosis and missed diagnosis rates are typically high. We present the case of a middle-aged male patient who developed fever, chills, anal distension, dizziness, and muscle pain for 10 days. The patient had a documented history of cat bites 1 month prior to the onset of symptoms. Following admission, he underwent an examination to determine superficial lymphadenopathy and hypoimmunity. Additionally, he had a fever during the disease. As the patient refused a needle biopsy of lymph nodes, metagenomic next-generation sequencing (mNGS) was employed and B. henselae was detected in the peripheral blood. The patient was diagnosed with CSD and treated with a combination of azithromycin and doxycycline. The fever symptoms were alleviated, and the patient was ultimately discharged. As a result of this case, we suggest that mNGS be used as a crucial supplementary diagnostic tool for individuals with compromised immune systems who may have CSD, especially when conventional diagnostic methods are inconclusive.

Growth and anemia among children with tuberculosis infection at different sites in Southwest China.

Objectives: To explore the effects of tuberculosis (TB) infection at different sites on anthropometric indicators, malnutrition and anemia incidence in children in Southwest China. Methods: From January 2012 to December 2021, a total of 368 children aged 1 month to 16 years were enrolled. According to the sites of TB infection, they were divided into three groups: tuberculous meningitis (T group), tuberculous meningitis complicated withpulmonary tuberculosis (TP group), and tuberculous meningitis complicated with pulmonary tuberculosis and abdominal tuberculosis (TPA group). Data on weight, height, nutritional risk, blood biochemical indicators and basic descriptions were collected within 48 h after admission. Results: The body mass index-for-age z score (BAZ), height-for-age z score (HAZ), and concentrations of hemoglobin (Hb) and albumin (ALB) decreased in the following order: T group, TP group, and TPA group. The prevalence of malnutrition was the highest in the TPA group (69.5%, 82/118) and 10-to 16-year-old group (72.4%, 63/87). Children aged 0.5-2 years exhibited the highest anemia prevalence of 70.6% (48/68) among the four age groups.The TPA group had the highest incidence of anemia (70.5%, 67/95) compared to T group and TP group.Compared with the treatment group, the abandonment group had a lower BAZ, HAZ and levels of HB and ALB, a higher rate of severe malnutrition, and higher nutritional risk scores. Children who had a low BAZ [odds ratio (OR) = 1.98], nutritional risk (OR = 0.56) and anemia (OR = 1.02) were less likely to obtain treatment with their guardians' support. Conclusions: Children with tuberculous meningitis were at risk for growth disorders and anemia, especially when complicated with pulmonary tuberculosis and abdominal tuberculosis. The prevalence of anemia and malnutrition was the highest among patients aged 1 month to 2 years and 10-16 years, respectively. Nutritional status was one of the causes of abandoning treatment.

Intuitive thinking impedes cooperation by decreasing cooperative expectations for pro-self but not for pro-social individuals.

This study conducted two experiments to explore the effects of intuitive thinking and social value orientation (SVO) on cooperative behavior and assess the mediating effect of cooperative expectations. It manipulated intuitive thinking by increasing the participants' need for cognitive closure, classified SVO using the triple-dominance measure, measured cooperative behavior using the prisoner's dilemma game, and considered cooperative expectations based on participants' assessments of the cooperativeness of their counterparts. Both experiments showed that intuitive thinking increased and decreased the cooperation of pro-social and pro-self individuals, respectively. In pro-self individuals, cooperative expectations mediated the effect of intuitive thinking on cooperation.

pNaktide mitigates inflammation-induced neuronal damage and behavioral deficits through the oxidative stress pathway.

Neuroinflammation is closely related to the etiology and progression of neurodegenerative diseases such as Parkinson disease and Alzheimer disease. pNaktide, an Src inhibitor, exerts antioxidant effects by mimicking Na/K-ATPase. It has been verified that its anti-inflammation and anti-oxidation ability could be embodied in obesity, steatohepatitis, uremic cardiomyopathy, aging, and prostate cancer. This study aimed to investigate the effects and mechanisms of pNaktide in lipopolysaccharide (LPS)-induced behavioral damage, neuroinflammation, and neuronal damage. We found that pNaktide improved anxiety, memory, and motor deficits. pNaktide inhibited MAPK and NF-κB pathways induced by TLR4 activation, inhibited the NLRP3 inflammasome complex, and reduced the expression of inflammatory factors, complement factors, and chemokines. pNaktide inhibited the activation of Nrf2 and HO-1 antioxidant stress pathways by LPS and reduced the level of oxidative stress. Inhibition of autophagy and enhancement of apoptosis induced by LPS were also alleviated by pNaktide, which restored LPS-induced injury to newborn neurons in the hippocampus region. In summary, pNaktide attenuates neuroinflammation, reduces the level of oxidative stress, has neuroprotective effects, and may be used for the treatment of neuroinflammation-related diseases.

Optimal design of aperiodic tri-slot antennas for the conformal ablation of liver tumors using an experimentally validated MWA computer model.

OBJECTIVE: This study aims to demonstrate that the conformal microwave ablation (MWA) of liver tumors could be attained by optimizing the structure of an aperiodic tri-slot coaxial antenna, its insertion depth, and input power. METHODS: A computational MWA model with an aperiodic tri-slot coaxial antenna operating at the frequency of 2.45 GHz was built and validated by both an ex vivo and a pilot in vivo experiment with porcine healthy livers. The validated in vivo computational MWA model implemented with a liver tumor was then used as a testbed to investigate the conformal ablation of liver tumors. Five liver tumors in different sizes and shapes were investigated. A genetic algorithm optimization method (NSGA-II) was used to optimize the structure of antenna, insertion depth of antenna, and microwave antenna input power for the conformal ablation of liver tumors. RESULTS: The validation results showed that a good agreement in both the spatiotemporal temperature distribution and ablation zone was found between the computer model and the ex vivo experiments at both 45 W, 5 min and 60 W, 3 min treatments and the in vivo experiment at 45 W, 5 min treatment. The optimized simulation results confirmed that five cases of liver tumors in different sizes and shapes can be conformally ablated by optimizing the aperiodic tri-slot coaxial antenna, antenna insertion depth, and microwave antenna input power. CONCLUSION: This paper demonstrates that the aperiodic tri-slot coaxial antenna can be optimized with the insertion depth and input power for the conformal ablation of liver tumors, regardless the size and shape of liver tumors.
