ObjectiveTo decipher the mechanism by which Zuoguiwan (ZGW) treat hyperthyroidism in rats with kidney-Yin deficiency based on the dopamine receptor D4 (DRD4)/nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 4 (NOX4) signaling pathway. MethodsThe rat model of kidney-Yin deficiency was induced by unilateral intramuscular injection of dexamethasone (0.35 mg·kg-1). After successful modeling, the rats were randomized into model, methimazole (positive control, 5 mg·kg-1), low-, medium-, and high-dose (1.85, 3.70, 7.40 g·kg-1, respectively) ZGW, and normal control groups. After 21 days of continuous gavage, the behavioral indexes and body weight changes of rats were evaluated. The pathological changes of the renal tissue were observed by hematoxylin-eosin staining. The serum levels of thyroid hormones [triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH)], renal function indexes [serum creatine (Scr) and blood urea nitrogen (BUN)], energy metabolism markers [cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP)], and oxidative stress-related factors [superoxide dismutase (SOD), malondialdehyde (MDA), and NADPH)] were measured by enzyme-linked immunosorbent assay (ELISA). Western blot was employed to analyze the expression of DRD4, NOX4, mitochondrial respiratory chain complex proteins [NADH:ubiquinone oxidoreductase subunit S4 (NDUFS4) and cytochrome C oxidase subunit 4 (COX4)], and inflammation-related protein [tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), p38 mitogen-activated protein kinase (MAPK)] pathway in the renal tissue. ResultsCompared with the normal group, the model group showed mental malaise, body weight decreases (P<0.01), inflammatory cell infiltration in the renal tissue, a few residual parotid glands in the thyroid, elevations in serum levels of T3, T4, Scr, BUN, cAMP, cAMP/cGMP, MDA, and NADPH (P<0.01), down-regulation in protein levels of TSH, SOD, and DRD4 (P<0.05, P<0.01), and up-regulation in expression of NOX4, p-p38 MAPK/p38 MAPK, and inflammatory factors (P<0.01). Compared with the model group, ZGW increased the body weight (P<0.05, P<0.01), reduced the infiltration of renal interstitial inflammatory cells, restored the thyroid structure and follicle size, lowered the serum levels of T3, T4, Scr, BUN, cAMP, cAMP/cGMP, MDA and NADPH (P<0.05, P<0.01), up-regulated the expression of TSH, SOD and DRD4 (P<0.05, P<0.01), and down-regulated the expression of NOX4, p-p38 MAPK/p38 MAPK, and inflammatory factors (P<0.05, P<0.01). Moreover, high-dose ZGW outperformed methimazole (P<0.05). ConclusionBy activating DRD4, ZGW can inhibit the expression of NOX4 mediated by the p38 MAPK pathway, reduce oxidative stress and inflammatory response, thereby ameliorating the pathological state of hyperthyroidism due to kidney-Yin deficiency. This study provides new molecular mechanism support for the clinical application of ZGW.

Objective: To investigate the distribution frequency and molecular mechanism of the rare blood type Lu(a-b-) in Shenzhen, and to compare the polymorphisms of the Lutheran blood group system encoding gene LU and the In (Lu) phenotype-related gene KLF1 among Han Chinese, Indian, and Uyghur populations in Xinjiang. Methods: Serological methods were used to screen the Lu(a-b-) phenotype of blood donors in Shenzhen. Third-generation sequencing was employed to sequence the full-length of the LU and KLF1 genes in Lu (a-b-) phenotype samples as well as the samples from the Han Chinese, Indians, and Uyghur population, followed by analysis of gene haplotypes frequencies. Results: Ten individuals with the Lu(a-b-) phenotype were screened out of 14 367 blood donors in Shenzhen, yielding a frequency of approximately 0.07%. Only 2 cases showed mutations in the coding region of the LU gene, while all individuals showed heterozygous mutations in the coding region of the KLF1 gene. The highest mutation frequencies of the LU and KLF1 genes were observed in the Uyghur population in Xinjiang and the Han Chinese in Shenzhen, respectively. Conclusion: All Lu(a-b-) phenotypes are of the In (Lu) type, and their formation mechanism is mainly related to KLF1 gene mutations. Both the LU and KLF1 genes exhibit significant polymorphism in the Han Chinese, Indians, and Uyghur populations.

BackgroundAnxiety exhibits a rising prevalence among college students. Investigating the mechanisms through which family function relates to anxiety and examining the moderating role of emotion regulation strategies within this context hold substantial implications for promoting mental health among college students. However, existing research has not sufficiently elucidated the complex interplay among family function, emotion regulation, and anxiety among college students. Further research is warranted to clarify the underlying mechanisms linking family function to anxiety outcomes and to examine the potential moderating role of emotion regulation strategies in this causal pathway. ObjectiveTo explore the relationship between family function and anxiety among lower-grade college students, and to validate the moderating role of emotion regulation strategies in this relationship, thereby offering evidence-based insights for anxiety reduction interventions in this population. MethodsIn March 2023, a total of 1 980 first- and second-year students from a comprehensive university in Shanghai were selected using the cluster sampling method. A self-designed demographic questionnaire, the Emotion Regulation Questionnaire (ERQ), the Family Adaptability and Cohesion Evaluation Scale Ⅱ-Chinese Version (FACES Ⅱ-CV), and the Symptom Checklist-90 (SCL-90) were utilized for assessment. Pearson correlation analysis and Spearman correlation analysis were employed to test the correlations of each variable. Hierarchical linear regression analysis was conducted to certify the moderating role of emotion regulation strategies in the relationship between family function and anxiety. ResultsCompared with female students, male students scored significantly lower on ERQ cognitive reappraisal (t=-5.793, P<0.01) but significantly higher on ERQ expressive suppression (t=8.359, P<0.01). For lower-grade college students, scores on adaptability and cohesion subscales of FACES Ⅱ-CV showed a positive association with cognitive reappraisal in ERQ (r=0.251, 0.302, P<0.01), while simultaneously displaying negative correlations with both expressive suppression in ERQ (r=-0.113, -0.154, P<0.01) and anxiety in SCL-90 (r=-0.243, -0.202, P<0.01). Notably, anxiety scores in SCL-90 were inversely related to cognitive reappraisal scores in ERQ (r=-0.159, P<0.01) but directly associated with expressive suppression scores in ERQ (r=0.171, P<0.01). Hierarchical regression analysis indicated that cognitive reappraisal significantly moderated the relationship between family cohesion and anxiety (β=-0.421, P<0.01). ConclusionThe cognitive reappraisal strategy serves as a moderator in the relationship between family cohesion and anxiety, potentially mitigating the escalation of anxiety levels associated with family dysfunction.

Objective To analyze the effect of releasing the lower pulmonary ligament on right residual lung expansion after right upper lobe resection under different body mass index (BMI) levels. Methods The clinical data of patients who underwent thoracoscopic right upper lobe resection in the First Affiliated Hospital with Nanjing Medical University from 2021 to 2022 were retrospectively analyzed. Patients were divided into a group A (17 kg/m2<BMI≤23 kg/m2), a group B (23 kg/m2<BMI≤29 kg/m2) and a group C (BMI>29 kg/m2) according to BMI. The presence of residual cavity was judged by chest X-ray at 7-10 days after operation, the degree of compensation change of the right main bronchus angle was measured, and the changes in lung volume were determined by CT three-dimensional reconstruction. Results A total of 157 patients who underwent thoracoscopic right upper lobe resection were included, including 71 males and 86 females, with an average age of (59.7±11.2) years. There were 50 patients in the group A, 75 patients in the group B, and 32 patients in the group C. In the group A, compared with those without releasing the lower pulmonary ligament, patients with releasing had a lower incidence of postoperative residual cavity (P=0.016), greater changes in bronchus angle (P<0.001), and smaller changes in lung volume (P<0.001). In the group B and C, there was no significant effect of releasing the lower pulmonary ligament on postoperative residual cavity, bronchus angle, and lung volume changes (P>0.05). Conclusion For patients with thin and long body shape and low BMI, releasing the lower pulmonary ligament is helpful to promote the expansion of the residual lung after right upper lobe resection and reduce the occurrence of postoperative residual cavity in patients.

BACKGROUND:Buqi Huoxue Compounds have significant clinical efficacy in treating ischemic stroke with Qi deficiency and phlegm stasis;however,the exact mechanism of action is not clear. OBJECTIVE:To observe the effect of Buqi Huoxue Compounds on the expression of vascular endothelial growth factor,basic fibroblast growth factor,brain-derived neurotrophic factor and autophagy related protein Beclin1 and p62 in a rat model of cerebral ischemia/reperfusion. METHODS:Forty male Sprague-Dawley rats were randomly divided into sham operation group,model group,Buqi Huoxue Compounds group and autophagy inhibitor group,with 10 rats in each group.In the latter three groups,a rat model of cerebral ischemia/reperfusion injury was established.The Buqi Huoxue Compounds group was intragastrically given Buqi Huoxue Compounds(6.49 g/kg,administered three times a day)2 hours after reperfusion;the autophagy inhibitor group was intragastrically given Buqi Huoxue Compounds(6.49 g/kg,administered three times a day)2 hours after reperfusion and intraperitoneally given 3-methyladenine 2 hours before gavage and at days 1-3 of gavage.The sham operation group and model group were given equal amounts of saline by gavage for 7 consecutive days.Neurological function,cerebral infarct volume,brain tissue morphology and expression of vascular endothelial growth factor,basic fibroblast growth factor,brain-derived neurotrophic factor and autophagy-related proteins Beclin1 and p62 in the ischemic cortical region of rats were detected at 24 hours after the final administration. RESULTS AND CONCLUSION:Zea-Longa scoring results showed that the neurological function of rats was severely damaged after modeling and neurological deficit of rats in the Buqi Huoxue Compounds group was less than that in the model group and the autophagy inhibitor group(P<0.05).TTC staining showed that cerebral infarct foci were observed in the model group,Buqi Huoxue Compounds group,and autophagy inhibitor group,and the cerebral infarct volume in the Buqi Huoxue Compounds group was lower than that in the model group and the autophagy inhibitor group(P<0.05).The results of hematoxylin-eosin staining in ischemic brain tissues showed that there were large gaps between nerve cells in the model group and cell arrangement was not neat,and cytoplasmic agglutination and pyknosis were observed.Immunohistochemical staining results showed that vascular endothelial growth factor was mostly expressed in neuronal cells,glial cells and capillary endothelium;basic fibroblast growth factor and brain-derived neurotrophic factor were mostly expressed in neuronal cells and glial cells;and there was no significant difference in the expression of vascular endothelial growth factor,basic fibroblast growth factor,and brain-derived neurotrophic factor among the four groups(P>0.05).The results of western blot assay showed that compared with the sham operation group,Beclin1 protein expression was decreased(P<0.05)and p62 protein expression was elevated(P<0.05)in the model group;compared with the model group,Beclin1 protein expression was increased(P<0.05)and p62 protein expression was reduced(P<0.05)in the Buqi Huoxue Compounds group;compared with the Buqi Huoxue Compounds group,Beclin1 protein expression was decreased(P<0.05)and p62 protein expression was elevated(P<0.05)in the autophagy inhibitor group.To conclude,Buqi Huoxue Compounds attenuate cerebral ischemia-reperfusion injury in rats by promoting autophagy.

Objective:
This study aimed to explore the correlation between balance function and core muscle activation in patients with adolescent idiopathic scoliosis (AIS), compared to healthy individuals.
Methods:
A total of 24 AIS patients and 25 healthy controls were recruited. The limits of stability (LOS) test were conducted to assess balance function, while surface electromyography was used to measure the activity of core muscles, including the internal oblique, external oblique, and multifidus. Diaphragm thickness was measured using ultrasound during different postural tasks. Center of pressure (COP) displacement and trunk inclination distance were also recorded during the LOS test.
Results:
AIS patients showed significantly greater activation of superficial core muscles, such as the internal and external oblique muscles, compared to the control group (p < 0.05). Diaphragm activation was lower in AIS patients during balance tasks (p < 0.01). Although no significant difference was observed in COP displacement between the groups, trunk inclination was significantly greater in the AIS group during certain tasks (p < 0.05).
Conclusion
These findings suggest distinct postural control patterns in AIS patients, highlighting the importance of targeted interventions to improve balance and core muscle function in this population.

Objective To investigate the population density and seasonal fluctuations of Aedes albopictus in Guangzhou City, Guangdong Province, from 2021 to 2023, so as to provide insights into A. albopictus control and management of dengue fever. Methods The surveillance of A. albopictus density was performed in all surveillance sites assigned across all streets (townships) in Guangzhou City during the period from January to December from 2021 to 2023. The surveillance frequency was twice every half month from May to September, and once every month for the rest of a year. In each surveillance period, A. albopictus mosquito larvae were captured from indoor and outdoor small water containers in residential areas, parks, medical facilities, schools, other government sectors and social organizations, construction sites, special industries and others for mosquito species identification. Adult mosquitoes were captured using electric mosquito suction apparatus for species identification and gender classification. Adult mosquitoes and mosquito eggs were collected with mosquito and egg traps at the breeding and dwelling places of Aedes mosquitoes for identification. The mosquito oviposition index (MOI), Breteau index (BI), adult mosquito density index (ADI) and standard space index (SSI) were calculated. The A. albopictus density was classified into grades 0, 1, 2 and 3 in each surveillance site, with Grade 0 density defined eligible, and the eligible rate of A. albopictus density was calculated at all surveillance sites each year from 2021 to 2023. In addition, the changing trends in MOI, SSI, BI and ADI of A. albopictus were analyzed in Guangzhou City from 2021 to 2023. Results The eligible rates of A. albopictus density were 61.69%, 68.75% and 55.15% in surveillance sites of Guangzhou City from 2021 to 2023 (χ2 = 297.712, P < 0.001), and appeared a tendency towards a reduction followed by a rise each year, which gradually reduced since January, maintained at a low level during the period between May and October, and gradually increased from November to December. The MOI, SSI, BI and ADI of A. albopictus all appeared a tendency towards a rise followed by a reduction in Guangzhou City during the period between January and December from 2021 to 2023. The BI of A. albopictus peaked in the first half of June in 2021 (4.03), the first half of July in 2022 (3.89) and the last half of August in 2023 (5.02), and the SSI of A. albopictus peaked in the last half of June in 2021 (0.93), the last half of May in 2022 (0.59), and the last half of June (0.94) and the first half of September in 2023 (1.12). In addition, the MOI of A. albopictus peaked in the first half of May in 2021 (8.64), the first half of June in 2022 (8.96), and the last half of May (10.21) and the last half of June in 2023 (10.89), and the ADI of A. albopictus peaked in the first half of June in 2021 (3.41), the last half of June in 2022 (4.06), and the first half of July in 2023 (3.61). Conclusions The density of A. albopictus is high in Guangzhou City during the period from May to October, and the risk of local outbreak caused by imported dengue fever is high. Persistent intensified surveillance of the density and seasonal fluctuation of A. albopictus is recommended and timely mosquito prevention and control is required according to the fluctuation in the A. albopictus density.

ObjectiveTo understand the infection characteristics of multidrug-resistant organisms (MDROs) in hospitalized patients in a tertiary sentinel hospital in Shanghai, so as to provide an evidence for the development of targeted prevention and control measures. MethodsData of MDROs strains and corresponding medical records of some hospitalized patients in a hospital in Shanghai from 2021 to 2023 were collected, together with an analysis of the basic information, clinical treatment, underlying diseases and sources of sample collection. ResultsA total of 134 strains of MDROs isolated from hospitalized patients in this hospital were collected from 2021 to 2023 , including 63 strains of methicillin-resistant Staphylococcus aureus (MRSA), 57 strains of carbapenem-resistant Acinetobacter baumannii (CRAB), and 14 strains of carbapenem-resistant Klebsiella pneumoniae (CRKP). Of the 134 strains, 30 strains were found in 2021, 47 strains in 2022 and 57 strains in 2023. The male-to-female ratio of patients was 2.05∶1, with the highest percentage (70.90%) in the age group of 60‒<90 years. The primary diagnosis was mainly respiratory disease, with lung and respiratory tract as the cheif infection sites. There was no statistically significant difference in the distribution of strains between different genders and infection sites (P>0.05). However, the differences in the distribution of strains between different ages and primary diagnosis were statistically significant (P<0.05). Patients who were admitted to the intensive care unit (ICU), had urinary tract intubation, were not artery or vein intubated, were not on a ventilator, were not using immunosuppresants or hormones, and were not applying radiotherapy or chemotherapy were in the majority. There was no statistically significant difference in the distribution of strains for whether received radiotherapy or chemotherapy or not (P>0.05), while the differences in the distribution of strains with ICU admission history, urinary tract intubation, artery or vein intubation, ventilator use, and immunosuppresants or hormones use or not were statistically significant (all P<0.05). The type of specimen was mainly sputum, the hospitalized ward was mainly comprehensive ICU, the sampling time was mainly in the first quarter throughout the year, the number of underlying diseases was mainly between 1 to 2 kinds, the application of antibiotics ≥4 kinds, and those who didn’t receive any surgery recently accounted for the most. There were statistically significant differences in the distribution of strains between different specimen types, wards occupied and history of ICU stay (P<0.05), but no statistically significant difference in the distribution of strains between different sampling times, number of underlying diseases and types of antibiotics applied (P>0.05). ConclusionThe situation of prevention and control on MDROs in this hospital is still serious. Focus should be placed on high-risk factors’ and infection monitoring and preventive measures should be strengthened to reduce the incidence rate of MDROs infection.
