The auxin/indole-3-acetic acid (Aux/IAA) gene family is an important regulator for plant growth hormone signaling, involved in plant growth, development, as well as response to environmental stresses. In the present study, we identified SmIAA7 which is potentially associated with Salvia miltiorrhiza leaf development through comparatively analyzed the transcriptome data from different pinnate leaves. SmIAA7 was successfully isolated from S. miltiorrhiza using the specific primers. Then subsequent bioinformatic analysis, prokaryotic expression and purification, subcellular localization, and induction expression analysis under auxin and abiotic stress were performed. The full-length of SmIAA7 contained an ORF of 684 bp encoding a protein of 227 amino acid with a molecular weight of 25.3 kD. Conserved domain analysis showed that SmIAA7 contains the conserved Aux_IAA domain (pfam02309). Sequence analysis and phylogenetic tree analysis results indicated SmIAA7 was phylogenetically close to IAA7 and IAA14 from other plants, suggesting SmIAA7 involved in plant growth and development as well as response to environmental stresses. The prokaryotic expression vector pET28a-SmIAA7 was constructed and SmIAA7 recombinant protein was successfully expressed in E. coli Rosetta (DE3) strain. Subcellular localization experiment demonstrated that SmIAA7 localized in the nucleus of plant cells. Real-time fluorescence quantitative PCR results showed that the expression level of SmIAA7 was upregulated in response to auxin. Drought, low temperature, and salt stress significantly increased the transcript level of SmIAA7 gene. This study lays a foundation for further elucidating the role of SmIAA7 in leaf development, signal transduction, and stress defense in S. miltiorrhiza.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To investigate the occurrence of adverse events of lurasidone in the U.S.Food and Drug Administration Adverse Event Reporting System(FAERS)database by using Open Vigil FDA2.1,to enrich the experience and provide the basis for the clinical use of the drug in China.Methods Using Open Vigil FDA2.1,adverse event data were extracted from the FAERS database for a total of 51 quarters from the 4th quarter of 2010 to the 3rd quarter of 2023,and the ratio of reporting ratio(ROR)method and the proportional reporting ratio(PRR)method were used for data mining and analysis.Results A total of 32 728 adverse event reports with lurasidone as the first suspected drug was obtained,with a larger proportion of females(54.26％)and occurring mostly in adults(18 to 59 years).After the screening,326 preferred term(PT)signals were obtained,involving 20 system-organ classifications(injury,poisoning and procedural complications,general disorders and administration site conditions,psychiatric disorders,etc.).Among them,PTs with the higher frequency of occurrence included off label use,feeling abnormal,crying,anxiety,depression,insomnia,etc.PTs with stronger signal strength included activation syndrome,mania,tongue movement disturbance,hypoprolactinaemia,akathisia,etc.Multiple new suspected adverse drug reactions were unearthed,including hypoprolactinaemia,emotional poverty,stiff tongue,etc.Conclusion Lurasidone has a favorable safety profile,and women need to closely monitor prolactin levels when taking this medication.The drug is relatively safe for use in pregnant,puerperal and perinatal women and patients with poor metabolic function.Hypoprolactinaemia and restless leg syndrome are new rare suspected adverse events with lurasidone.

ObjectiveThe absorption of substances into blood is mainly dependent on the mesenteric lymphatic pathway and the portal venous pathway. The substances transported via the portal venous pathway can be metabolized by the biotransformation in the liver. On the contrary, the substances in the mesenteric lymph fluid enter the blood circulation without biotransformation and can affect the body directly. Alcohol consumption is strongly linked to global health risk. Previous reports have analyzed the changes of metabolites in plasma, serum, urine, liver and feces after alcohol consumption. Whether alcohol consumption affects the metabolites in lymph fluid is still unknown. Therefore, it is particularly important to explore the changes of substances transported via the mesenteric lymphatic pathway and analyze their harmfulness after alcohol drinking. MethodsIn this study, male Wistar rats were divided into high, medium, and low-dosage alcohol groups (receiving Chinese Baijiu at 56%, 28% and 5.6% ABV, respectively) and water groups. The experiment was conducted by alcohol gavage lasting 10 d, 10 ml·kg^-1·d^-1. Then mesenteric lymph fluid was collected for non-targeted metabolomic analysis by using liquid chromatography-mass spectrometry (LC-MS) and bioinformatic analysis. Principal component analysis and hierarchical clustering were performed by using Biodeep. Meanwhile, KEGG enrichment analysis of the differential metabolites was also performed by Biodeep. MetaboAnalyst was used to analyze the relationship between the differential metabolites and diseases. ResultsThe metabolites in the mesenteric lymph fluid of the high-dosage alcohol group change the most. Based on the KEGG enrichment analysis, the pathways of differential metabolites between the high-dosage alcohol group and the control group are mainly enriched in the central carbon metabolism in cancer, bile secretion, linoleic acid metabolism, biosynthesis of unsaturated fatty acids, etc. Interestingly, in the biosynthesis of unsaturated fatty acids category, the content of arachidonic acid is increased by 7.25 times, whereas the contents of palmitic acid, oleic acid, stearic acid, arachidic acid and erucic acid all decrease, indicating lipid substances in lymph fluid are absorbed selectively after alcohol intake. It’s worth noting that arachidonic acid is closely related to inflammatory response. Furthermore, the differential metabolites are mainly related with schizophrenia, Alzheimer’s disease and lung cancer. The differential metabolites between the medium-dosage alcohol and the control group were mainly enriched in phenylalanine metabolism, valine, leucine and isoleucine biosynthesis, linoleic acid metabolism and cholesterol metabolism. The differential metabolites are mainly related to schizophrenia, Alzheimer’s disease, lung cancer and Parkinson’s disease. As the dose of alcohol increases, the contents of some metabolites in lymph fluid increase, including cholesterol, L-leucine, fumaric acid and mannitol, and the number of metabolites related to schizophrenia also tends to increase, indicatingthat some metabolites absorbed by the intestine-lymphatic pathway are dose-dependent on alcohol intake. ConclusionAfter alcohol intake, the metabolites transported via the intestinal-lymphatic pathway are significantly changed, especially in the high-dosage group. Some metabolites absorbed via the intestinal-lymphatic pathway are dose-dependent on alcohol intake. Most importantly, alcohol intake may cause inflammatory response and the occurrence of neurological diseases, psychiatric diseases and cancer diseases. High-dosage drinking may aggravate or accelerate the occurrence of related diseases. These results provide new insights into the pathogenesis of alcohol-related diseases based on the intestinal-lymphatic pathway.

The breakage pattern of unit particles during the production of oral solid dosage forms (OSD) is closely related to the quality of intermediate or final products. To accurately characterize the particles and study the evolution law of particle breakage, the Bonding model of the discrete element method (DEM) was used to investigate the breakage patterns of model parameters, particle shape and process conditions (loading mode and loading rate) on the dynamic breakage, force-time curve, breakage rate, maximum breakage size ratio and fracture strength of particles. The results showed that the particle breakage force was positively correlated with normal strength and bonded disk scale, negatively correlated with normal stiffness per unit area and tangential stiffness per unit area, and weakly correlated with tangential strength. The particle breakage rate was negatively correlated with the aspect ratio of the particles, and the maximum breakage size ratio was positively correlated with the aspect ratio of the particles; among the three loading modes, the breakage rate of compression breakage model was the largest, the breakage rate of shear breakage model was the second largest, and the breakage rate of wear breakage model was the smallest; the maximum breakage size ratio was positively correlated with the loading rate, the loading mode and the loading rate had no mutual influence on particle breakage rate, but had mutual influence on the maximum breakage size ratio. The research results will provide a theoretical basis for the shift of OSD from batch manufacturing to advanced manufacturing.

As a major global public health problem, pulmonary diseases threaten human life and health while causing a huge economic burden. The messenger RNA (mRNA)-based inhalation preparation, which effectively targets pulmonary cells can overcome the problems of traditional therapy, such as high side effects, low pulmonary bioavailability, and difficulty in synthesizing target proteins in vitro, thus providing new ideas for the treatment of pulmonary diseases. However, as the lung structure is complex and mRNA has trouble entering cells, researchers have been attempting to develop a suitable nano delivery system for higher delivery efficiency. This review introduces the barriers to pulmonary delivery, discusses the recent research development of the mRNA pulmonary delivery systems, including lipid nanoparticles, polymeric nanoparticles, polypeptides and exosomes, summarizes their limitations and looks forward to the application of mRNA inhalation preparations.

Purpose: This study aimed to analyze the expression and prognosis of SRY-box transcription factor 11 (SOX11) in neuroblastoma (NB), as well as the biological function and potential regulatory mechanism of SOX11 in NB. Methods: Public RNA sequencing was used to detect the expression level of SOX11. The Kaplan-Meier curve and hazard ratios (HR) were used to determine the prognostic value of SOX11 in NB. Functional analyses were performed using CCK8, wound healing assay, and transwell invasion assay. Finally, the potential target genes of SOX11 were predicted by Harmonizonme (Ma'ayan Laboratory) and Cistrome Data Browser (Cistrome Project) database to explore the potential molecular mechanism of SOX11 in NB. Results: Compared with normal adrenal tissue, the expression of SOX11 in NB tissue was significantly upregulated. The Kaplan-Meier curve showed that high expression of SOX11 was associated with poor prognosis in children with NB (HR, 1.719; P = 0.049). SOX11 knockdown suppressed the migration capacity of SK-N-SH cells but did not affect proliferation and invasion capacity. Enhancer of zeste homolog 2 (EZH2) may be a potential downstream target gene for the transcription factor SOX11 to play a role in NB. Conclusion The transcription factor SOX11 was significantly upregulated in NB. SOX11 knockdown suppressed the migration capacity of NB cell SK-N-SH. SOX11 may promote the progression of NB by targeting EZH2.

Background/Aims: Functional dyspepsia (FD) overlapping with other gastrointestinal disorders are quite common. The characteristics of FD overlap in Chinese population with latest Rome IV criteria were unclear. This large-scale outpatient-based study assessed the characteristics of FD overlap in South China. Methods: Consecutive FD patients visited the Gastroenterology Clinic at 2 tertiary medical centers in Hangzhou, China who fulfilled the Rome IV criteria were enrolled. Complete questionnaires related to the gastrointestinal symptoms (Rome IV criteria), Reflux Disease Questionnaire, anxiety and depression, quality of sleep and life, and demographic information were collected. Results: Among the total of 3281 FD patients, 50.69% overlapped with gastroesophageal reflux disease, 21.46% overlapped with irritable bowel syndrome, 6.03% overlapped with functional constipation. FD overlap had higher proportion of single/divorced/widowed rate, high education level, being employed, drinking, night shift, unhealthy dietary habit than FD only (P < 0.05). They had higher frequency of consultation and economic burden, as well as lower scores in quality of life (P < 0.001). Multivariate logistic regression showed that increasing age, female, low body mass index, history of gastroenteritis, anxiety, depression, and poor sleep quality were independent risk factors for FD overlap. Conclusions FD overlap was quite common in China with high economic burden and poor quality of life, FD patients with history of gastroenteritis, anxiety, depression, and poor sleep quality were more likely to have overlap disorders. Awareness of the physical and psychosocial stressors in overlapping condition would help optimize the management of FD overlap in clinical practice.

AIM: To evaluate retinal vascularization caused by the intravitreal injection of Conbercept in the treatment of a series of retinopathy of prematurity(ROP)cases in Type Ⅰ(threshold and pre-threshold period)and aggressive ROP(A-ROP).METHODS: The data of 34 ROP cases(67 eyes)treated by intravitreal injection of Conbercept(IVC)in the ophthalmology department of the Xiamen Children's Hospital from July 2017 to March 2020 were retrospectively analyzed. Reactivation, which refers to recurrence of acute phase features, occurred at any stage of the disease in the presence or absence of other diseases. RESULT: The average gestational age of the 34 children was 28.82±2.32wk. The average birth weight was 1155.18±398.22g. The lesion zone of 19 cases(37 eyes)was Zone Ⅰ. In 10 cases(20 eyes), the lesion was in Zone Ⅱ, and in 5 cases(10 eyes), the lesion was in the posterior Zone Ⅱ. The total effective rate of disease control in ROP children treated with once IVC was 73.1%(49/67), and the vascularization of Zone Ⅱ was completed. The patients showed variable changes in the vascularization in Zone Ⅲ. For the patients who received one treatment and did not reactivate, the average rate of Type Ⅰ vascularization of ROP was 9.11±2.49wk, and the A-ROP was 13.40±4.04wk. The rate of A-ROP vascularization in Zone Ⅱ was significantly longer compared to Type Ⅰ.CONCLUSION: IVC effectively completes vascularization in Zone Ⅱ.

Objective: To compare the surgical outcome of robotic thyroidectomy through transoral approach and the bilateral breast-axillary approach. Methods: Retrospective analysis was made on the clinical data of patients who performed transoral robotic thyroidectomy (TORT group) or bilateral breast-axillary approach (BABA group) in the Department of Thyroid and Breast Surgery, the 960th Hospital of People's Liberation Army from July 2020 to May 2022. Both groups received lobectomy with lymph node dissection of the central region. A total of 100 cases were included in the study, including 48 cases in the TORT group and 52 cases in the BABA group. The propensity score matching method was used for 1∶1 matching of patients between the 2 groups, with a match tolerance of 0.03. There were 31 patients in each group successfully matched. In the TORT group, there were 5 males and 26 females, aged (33.2±7.9) years (range: 21 to 53 years). While there were 4 males and 27 females in the BABA group, aged (34.6±9.2) years (range: 19 to 58 years). The t test, Mann-Whitney U test, χ² test or Fisher exact test were used to compare the clinical efficacy between the two groups. Results: All the patients successfully completed robotic thyroid surgery without conversion to open surgery. Compared with BABA group, the TORT group had longer operation time ((211.3±57.2) minutes vs. (126.2±37.8) minutes, t=6.915, P<0.01), shorter drainage tube retention time ((5.4±1.0) days vs. (6.4±1.2) days, t=-3.544, P=0.001), shorter total hospital stay ((6.6±1.2) days vs. (7.4±1.3) days, t=-2.353, P=0.022), and higher cosmetic score (9.46±0.25 vs. 9.27±0.26, t=2.925, P=0.005). There was no significant difference between the two groups in the number of lymph nodes dissection, metastasis in the central compartment, and the incidence of postoperative complications (all P>0.05). Conclusions: Compared with the bilateral breast-axillary approach, the transoral vestibular approach of robotic thyroidectomy is also safe and effective. It shows similar surgical results to the bilateral breast-axillary approach in strictly selected patients, but the postoperative recovery speed is much faster, and the hospital stay is shorter. Transoral robotic thyroidectomy is a more recommended surgical method for patients with high aesthetic demand.
