Chromosome-level genome assembly of Odontothrips loti Haliday (Thysanoptera: Thripidae).

As the predominant pest of alfalfa, Odontothrips loti Haliday causes great damages over the major alfalfa-growing regions of China. The characteristics of strong mobility and fecundity make them develop rapidly in the field and hard to be controlled. There is a shortage of bioinformation and limited genomic resources available of O. loti for us to develop novel pest management strategies. In this study, we constructed a chromosome-level reference genome assembly of O. loti with a genome size of 346.59 Mb and scaffold N50 length of 18.52 Mb, anchored onto 16 chromosomes and contained 20128 genes, of which 93.59% were functionally annotated. The results of 99.20% complete insecta_odb10 genes in BUSCO analysis, 91.11% short reads mapped to the ref-genome, and the consistent tendency among the thrips in the distribution of gene length reflects the quality of genome. Our study provided the first report of genome for the genus Odontothrips, which offers a genomic resource for further investigations on evolution and molecular biology of O. loti, contributing to pest management.

Optimization of table tennis target detection algorithm guided by multi-scale feature fusion of deep learning.

This paper aims to propose a table tennis target detection (TD) method based on deep learning (DL) and multi-scale feature fusion (MFF) to improve the detection accuracy of the ball in table tennis competition, optimize the training process of athletes, and improve the technical level. In this paper, DL technology is used to improve the accuracy of table tennis TD through MFF guidance. Initially, based on the FAST Region-based Convolutional Neural Network (FAST R-CNN), the TD is carried out in the table tennis match. Then, through the method of MFF guidance, different levels of feature information are fused, which improves the accuracy of TD. Through the experimental verification on the test set, it is found that the mean Average Precision (mAP) value of the target detection algorithm (TDA) proposed here reaches 87.3%, which is obviously superior to other TDAs and has higher robustness. The DL TDA combined with the proposed MFF can be applied to various detection fields and can help the application of TD in real life.

Sex differences in the association of childhood sexual abuse severity with premarital sex among Chinese college students in Luzhou, China.

PURPOSE: The adverse health consequences of premarital sex and childhood sexual abuse (CSA) are both global public health problems. Based on a random sample of college students from a Chinese city, this study investigated the relationship between CSA severity and premarital sex among students, focusing on sex differences. METHODS: A total of 2722 college students from 4 schools in Luzhou were recruited by multistage random sampling. Self-administered questionnaires were used to measure CSA experiences and premarital sex. Binary logistic regression analyses were conducted to analyse the relationship between CSA and premarital sex. RESULTS: The prevalence of CSA was 9.39%, and that of mild, moderate and severe CSA was 4.04%, 2.90% and 2.46%, respectively. The premarital sex reporting rate was 22.42%. After adjusting for confounding variables, CSA was positively associated with premarital sex. Notably, a cumulative effect of CSA on premarital sex was observed among students. Further stratification analyses showed that males who experienced CSA had a higher premarital sex rate than females, and this sex difference was also observed among students with different CSA severities. CONCLUSION: CSA and its severity were associated with premarital sex among college students. Furthermore, this association was stronger for males than females. Therefore, it is important to emphasize CSA prevention, especially for boys. These findings can promote understanding of the effects of CSA on premarital sex, and CSA prevention and intervention strategies should consider CSA severity and sex differences.

AIM:To measure the superficial capillary plexus(SCP)vessel density(VD), deep capillary plexus(DCP)VD, and the area, circumference, and roundness index of the foveal avascular zone(FAZ)in healthy individuals of four ethnic groups, namely, Uyghur, Han, Kazakh, and Hui by optical coherence tomography angiography(OCTA), and to investigate the differences of blood flow parameters in macular area of healthy individuals among different ethnic groups in China.METHODS: A total of 80 cases(80 eyes)of healthy subjects if each of the four ethnic groups who went to the Eye Center of the Friendship Hospital of Ili Kazak autonomous Prefecture from December 2022 to March 2023 and met the criteria were selected for the study, with 320 eyes totally. The patients were grouped and numbered according to their ethnicity, and the spherical equivalent and axial length were obtained by using an autorefractor and IOL Master. The blood flow images of the macular area in the range of 3 mm×3 mm were obtained by using a DRI Triton OCT detector, and the images were analyzed by using the built-in IMAGENET6 software to obtain the blood flow parameters. Furthermore, the differences in the blood flow parameters between different ethnic groups as well as the effects of gender, age, and axial length on macular blood flow parameters of different ethnic groups were compared.RESULTS:There were no statistically significant differences in gender, age, axial length, diopter, and image quality(IQ)among the four groups of subjects(all P>0.05). Ethnic differences: in SCP, Uyghur inferior VD is higher than Kazakh, Hui inferior VD is higher than Han and Kazakh, Han and Hui nasal VD is higher than Uyghur, Kazakh foveal VD is higher than Han and Hui, Kazakh FAZ area is smaller than the other 3 ethnic groups, Han and Hui FAZ perimeter is larger than Kazakh, and Hui FAZ circularity index is lower than the other 3 ethnic groups; in DCP, Uyghur foveal VD is higher than Han and Hui, Kazakh foveal VD is higher than Han and Hui, Kazakh FAZ area and perimeter are smaller than the other 3 ethnic groups and Kazakh FAZ circularity index is higher than the other 3 ethnic groups(all P<0.05). Sex differences: in SCP, FAZ area and perimeter of Han females were larger than those of males, and FAZ circularity index of Hui females was higher than that of males(all P<0.05); in DCP, parafoveal VD and whole VD in females of all four ethnic groups were higher than those of males(all P<0.05). Age correlation: in SCP, age was negatively correlated with the FAZ circularity index of Kazakh; in DCP, age was negatively correlated with the parafoveal and the whole VD of Han, Kazakh, and Hui(all P<0.05). Axial length correlation: in SCP, the axial length was negatively correlated with Kazakh and Hui foveal VD, Hui parafoveal VD, Uyghur, Kazakh and Hui whole VD, and positively correlated with Kazakh FAZ area and perimeter; in DCP, the axial length was negatively correlated with Uyghur, Kazakh, Hui foveal VD, Hui whole VD, and positively correlated with Kazakh and Hui FAZ area and perimeter(all P<0.05).CONCLUSION:There were differences in macular blood flow parameters among the Uyghur, Han, Kazakh, and Hui populations, with the area and perimeter of the FAZ of the Kazakh significantly smaller than those of the other three ethnic groups. Gender, age, and axial length are also related to macular blood flow parameters.

A case of neonatal Netherton syndrome / 中国当代儿科杂志

A male infant, aged 6 days, was admitted to the hospital due to respiratory distress and systemic desquamative rash after birth. The infant presented with erythema and desquamative rash, respiratory failure, recurrent infections, chronic diarrhea, hypernatremic dehydration, and growth retardation. Comprehensive treatment, including anti-infection therapy, intravenous immunoglobulin administration, and skin care, resulted in improvement of the rash, but recurrent infections persisted. Second-generation sequencing revealed a homozygous mutation in the SPINK5 gene, consistent with the pathogenic variation of Netherton syndrome. The family opted for palliative care, and the infant died at the age of 2 months after discharge. This report documents a case of Netherton syndrome caused by the SPINK5 gene mutation in the neonatal period, and highlights multidisciplinary diagnosis and therapy for this condition.

Application value of bone cement containing rhbFGF and RHBMP-2 in PKP treatment of osteoporotic lumbar compression fracture / 中国骨伤

OBJECTIVE@#To investigate the effect of bone cement containing recombinant human basic fibroblast growth factor (rhbFGF) and recombinant human bone morphogenetic protein-2 (rhBMP-2) in percutaneous kyphoplasty(PKP)treatment of osteoporotic vertebral compression fracture(OVCF).@*METHODS@#A total of 103 OVCF patients who underwent PKP from January 2018 to January 2021 were retrospectively analyzed, including 40 males and 63 females, aged from 61 to 78 years old with an average of (65.72±3.29) years old. The injury mechanism included slipping 33 patients, falling 42 patients, and lifting injury 28 patients. The patients were divided into three groups according to the filling of bone cement. Calcium phosphate consisted of 34 patients, aged(65.1±3.3) years old, 14 males and 20 females, who were filled with calcium phosphate bone cement. rhBMP-2 consisted of 34 patients, aged (64.8±3.2) years old, 12 males and 22 females, who were filled with bone cement containing rhBMP-2. And rhbFGF+rhBMP-2 consisted of 35 patients, aged (65.1±3.6) years old, 14 males and 21 females, who were filled with bone cement containing rhbFGF and rhBMP-2. Oswestry disability index (ODI), bone mineral density, anterior edge loss height, anterior edge compression rate of injured vertebra, visual analog scale (VAS) of pain, and the incidence of refracture were compared between groups.@*RESULTS@#All patients were followed for 12 months. Postoperative ODI and VAS score of the three groups decreased (P<0.001), while bone mineral density increased (P<0.001), anterior edge loss height, anterior edge compression rate of injured vertebra decreased first and then slowly increased (P<0.001). ODI and VAS of group calcium phosphate after 1 months, 6 months, 12 months were lower than that of rhBMP-2 and group rhbFGF+rhBMP-2(P<0.05), bone mineral density after 6 months, 12 months was higher than that of rhBMP-2 and group calcium phosphate(P<0.05), and anterior edge loss height, anterior edge compression rate of injured vertebra of group rhbFGF+rhBMP-2 after 6 months and 12 months were lower than that of group rhBMP-2 and group calcium phosphate(P<0.05). There was no statistical difference in the incidence of re-fracture among the three groups (P>0.05).@*CONCLUSION@#Bone cement containing rhbFGF and rhBMP-2 could more effectively increase bone mineral density in patients with OVCF, obtain satisfactory clinical and radiological effects after operation, and significantly improve clinical symptoms.

CfCpmd1 Regulates Pathogenicity and Sexual Development of Plus and Minus Strains in Colletotrichum fructicola Causing Glomerella Leaf Spot on Apple in China.

Colletotrichum fructicola is a devastating fungal pathogen of diverse plants. Sexually compatible plus and minus strains occur in the same ascus. However, the differentiation mechanism of plus and minus strains remains poorly understood. Here, we characterized a novel Cys2-His2-containing transcription factor CfCpmd1. The plus CfCpmd1 deletion mutant (Δ+CfCpmd1) resulted in slow hyphal growth and a fluffy cotton-like colony, and the minus deletion mutant (Δ-CfCpmd1) exhibited characters similar to the wild type (WT). Δ+CfCpmd1 led to defective perithecial formation, whereas Δ-CfCpmd1 produced more and smaller perithecia. The normal mating line was developed by pairing cultures of Δ-CfCpmd1 and plus WT, whereas a weak line was observed between Δ+CfCpmd1 and minus WT. Conidial production was completely abolished in both plus and minus mutants. When inoculated on non-wounded apple leaves with mycelial plugs, Δ-CfCpmd1 was nonpathogenic because of failure to develop conidia and appressoria, while Δ+CfCpmd1 could infect apple leaves by appressoria differentiated directly from hyphal tips, even though no conidia formed. Collectively, our results demonstrate that CfCpmd1 of C. fructicola is an important gene related to plus and minus strain differentiation, which also affects hyphal growth, sporulation, appressorium formation, and pathogenicity.

Comparison of high-flow nasal cannula and conventional oxygen therapy for high-risk patients during bronchoscopy examination: protocol for a randomized controlled trial.

INTRODUCTION: High-flow nasal cannula (HFNC) has been proven to improve oxygenation and avoid intubation in hypoxemic patients. It has also been utilized during endoscopy examination to reduce the incidence of hypoxia. However, little is known about the effects of HFNC versus conventional oxygen therapy (COT) on oxygenation during bronchoscopy examination via nasal route; particularly, no study has compared the use of HFNC with that of COT at similar FIO2 for patients who have high-risk factors of desaturation during bronchoscopy examination. METHODS AND ANALYSIS: This randomized controlled trial will be implemented in four academic centers in China. Patients who have high-risk factors including hypoxemia, hypercapnia, morbid obesity, and narrow airway will be enrolled to use HFNC or COT during bronchoscopy examination. In the HFNC group, the initial gas flow will be set at 50 L/min with a fraction of inspired oxygen (FIO2) at 0.45, if the patient tolerates, the flow can be increased to 60L/min at most, while in the COT group, oxygen flow will be set at 6 L/min via a conventional nasal cannula. After 5 min pre-oxygenation, the bronchoscope will be inserted via the nasal route. Vital signs, oxygenation (SpO2), and transcutaneous CO2 (PtCO2) will be continuously monitored. The primary outcome is the incidence of hypoxemia, defined as SpO2 < 90% for 10 s during bronchoscopy examination, and secondary outcomes include the need for treatment escalation and adverse events. DISCUSSION: Hypoxia is a common complication of bronchoscopy, our study attempted to demonstrate that HFNC may reduce the probability of hypoxia during bronchoscopy in high-risk patients. The results will be disseminated through peer-reviewed journals and national and international conferences. TRIAL REGISTRATION: http://www.chictr.org.cn/ : ChiCTR2100055038.

The risk of Alzheimer′s disease transmitted by blood transfusion based on APP/PS1 double transgenic mice / 中国输血杂志

【Objective】 To explore the risk of Alzheimer′s disease (AD) transmitted by blood transfusion. 【Methods】 There were 10 APP/PS1 mice of 3, 6 and 9 months old, half female and half male, and the cognitive and behavioral abilities of C57 mice of the same age were measured, and the blood of the oldest APP/PS1 mice with no behavioral changes were collected to detect the contents of Aβ40 and Aβ42. The polymers Aβ40 and Aβ42 were prepared and Western blotting analysis was conducted. Kunming mice aged from 6 to 7 months were randomly divided into 6 groups (10 mice/ group, half male and half female). The blood of APP/PS1 mice was injected intravenously in experimental group 1-2(100 μL/mouse) with high frequency injection (3 times/week) and low frequency injection (1 time/week), respectively. In experimental group 3-4, Aβ40 and Aβ42 polymerized mixture (100 μL/mouse) were injected in high frequency and low frequency, respectively. The control group 1-2 was injected with the same amount of normal saline, with high frequency and low frequency, respectively. The above groups were injected for 4 weeks, and the cognitive and behavioral abilities were tested and analyzed one week after injection. Finally, the contents of Aβ40 and Aβ42 in blood of Kunming mice were detected. 【Results】 Change in cognitive and behavioral ability showed in 9 months old APP/PS1 mice, but not in 3 and 6 months old APP/PS1 mice. The contents of Aβ40 and Aβ42 (pg/mL) in blood of 6-7 months old APP/PS1 mice were 418.40±2.18 and 15.68±0.20, respectively. Except for monomers, most of the polymerized mixtures of Aβ40 and Aβ42 were dimers and trimers. In both high frequency and low frequency, Kunming mice transfused with blood of APP/PS1 mice (experimental group 1-2) showed a certain degree of anxiety-like behavior and short-term memory shortening in open-field test and conditioned fear test, but without significant difference. There was no significant difference in open field test, new object recognition, Barnes maze and cognitive behavior analysis of conditioned fear between experimental group 3-4 and the control group. The levels of blood Aβ40 and Aβ42(pg/mL) of Kunming mice detected by ELISA were 10.30±0.08 and 3.360±0.005, respectively, and there was no significant difference between the two groups. 【Conclusion】 Blood transfusion of APP/PS1 mice and the mixture of Aβ40 and Aβ42 have no significant effect on the cognitive function of healthy Kunming mice in a short time, and the risk of AD transmission is relatively low.

Distribution and transfusion efficacy of unexpected antibody / 中国输血杂志

【Objective】 To investigate the clinical characteristics and antibody distribution as well as evaluate the transfusion efficacy in unexpected antibody positive patients. 【Methods】 A total of 12 235 patients from January 1, 2022 to March 31, 2023 who hospitalized in our hospital and applied for blood transfusion were selected, and those with unexpected antibody were included. The clinical data, including gender, age, diagnosis, blood type, history of transfusion and pregnancy were collected for antibody distribution analysis. Patients who received transfusion were grouped according to the DAT results and the components of red blood cells transfused, and the Hb values of each group before and after transfusion were compared. 【Results】 Among12 235 patients, 118 were positive for antibody screening, with a prevalence of 0.96%. The antibodies from Rh system were the most common (27.43%, 48/175), followed by MNS system (8.57%, 15/175) and Lewis system (6.29%, 11/175), mainly anti-E (18.29%, 32/175), anti-M (8.00%, 14/175) and anti-Lea (5.71%, 10/175). In addition, 62 transfused patients were divided into group A with suspended red blood cell transfusion and group B with washed red blood cell transfusion for positive DAT, and group C for negative DAT. Hb values (g/L) pre- and post-transfusion were 59.19±15.67 vs 77.52±15.09 in group A, 56.35±14.08 vs 74.44±15.63 in group B, 56.00±12.06 vs 75.00±4.73 in group C, respectively. The Hb values of post-transfusion for three groups were all higher than those of pre-transfusion (P<0.05). 【Conclusion】 Anti-E from Rh system is the most common antibody in patients with unexpected antibody. Appropriate red blood cells transfusion with Hb increases by an average of 6-7 g/L per 1 U of red blood cells indicating good transfusion efficacy. For positive DAT patients, transfusion of suspended red blood cell is feasible.

Investigation and analysis of a food poisoning incident caused by Vibrio parahaemolyticus / 上海预防医学

ObjectiveTo ascertain the causes of a food poisoning incident and provide references for the prevention of similar incidents in the future. MethodsCase investigation was conducted through field epidemiological investigation methods， and suspicious meals and foods were searched by the analytical epidemiological method. A food hygiene investigation was conducted in the establishment involved and samples of suspicious food， processing steps， and cases were collected for laboratory testing. ResultsA total of 91 individuals meeting the case definition were identified， resulting in an attack rate of 14.97% （91/608）. The main clinical manifestations included abdominal pain （97.80%）， diarrhea （84.62%）， nausea （62.64%）， vomiting （72.53%）， fever （12.09%）， and increased white blood cells （90.11%）. The peak incidence occurred from 16：00 to 18：00 on June 15. The epidemic curve showed a point-source exposure pattern， with an incubation period of 1 h minimum and 10 h maximum， and an average of 5 h. Analytical epidemiological studies indicated that lunch on June 15 was the suspicious meal （χ2=38.78， P<0.001）， and those who consumed cold-dressed tofu with preserved eggs had a significantly higher risk of falling ill compared to non-consumers （χ2=105.21， P<0.001）. Laboratory testing results revealed Vibrio parahaemolyticus detected in 1 employee’s anal swab and 18 cases’ anal swabs. Staphylococcus aureus was detected in 1 food ingredient and 1 case’s anal swab. The remaining samples tested negative. ConclusionThe cause of this food poisoning incident is Vibrio parahaemolyticus. The cause is the canteen’s supply of cold-dressed tofu with preserved eggs beyond its permissible business scope， potentially leading to cross-contamination during food processing. Regulatory authorities should strengthen routine law enforcement inspections and monitoring. Food service establishments should strengthen food safety awareness， standardize operational procedures in strict accordance with relevant national laws and regulations and food safety standards， and strive to reduce the occurrence of foodborne disease incidents at their source.

Patients who achieved complete/partial response after initial treatment had longer OS than those with stable or progressive disease (P <0.05). There were significant differences in OS and PFS among patients with different pathological types of primary cutaneous lymphoma that originated from T and NK/T cells, the OS and PFS of patients with mycosis fungoides were longer than those of patients with other pathological types (both P <0.05). In addition, disease stage might also affect the PFS of the patients (P =0.056).@*CONCLUSION@#The age, disease stage, β2-MG level, pathological type and remission state after treatment of the patients were related to the clinical prognosis.

Congenital pulmonary alveolar proteinosis in a neonate / 中国当代儿科杂志

The male patient was referred to the hospital at 44 days old due to dyspnea after birth and inability to wean off oxygen. His brother died three days after birth due to respiratory failure. The main symptoms observed were respiratory failure, dyspnea, and hypoxemia. A chest CT scan revealed characteristic reduced opacity in both lungs with a "crazy-paving" appearance. The bronchoalveolar lavage fluid (BALF) showed periodic acid-Schiff positive proteinaceous deposits. Genetic testing indicated a compound heterozygous mutation in the ABCA3 gene. The diagnosis for the infant was congenital pulmonary alveolar proteinosis (PAP). Congenital PAP is a significant cause of challenging-to-treat respiratory failure in full-term infants. Therefore, congenital PAP should be considered in infants experiencing persistently difficult-to-treat dyspnea shortly after birth. Early utilization of chest CT scans, BALF pathological examination, and genetic testing may aid in early diagnosis.

Heart failure caused by congenital hepatic hemangioma complicated with arteriovenous fistula in a neonate / 中国当代儿科杂志

The three-day-old female infant was admitted to the hospital due to respiratory distress after birth. She was born premature at 36+2 weeks gestational age. Prenatal ultrasound suggested abnormal development of the fetal liver vessels, and she had dyspnea that required respiratory support after birth. Chest X-ray indicated an enlarged cardiac silhouette, and cardiac ultrasound revealed enlargement of the right atrium and right ventricle. Diagnosis of hepatic hemangioma with arteriovenous fistula was confirmed through liver ultrasound and abdominal enhanced CT. At 19 days old, she underwent ligation of the hepatic artery under general anesthesia, which led to an improvement in cardiac function and she was subsequently discharged. Genetic testing revealed a mutation in the ACVRL1 gene, which was inherited from the mother. The article primarily introduces a case of neonatal heart failure caused by hepatic hemangioma with arteriovenous fistula, and multi-disciplinary diagnosis and treatment of this disease.
