RNAi mediated knockdown of RpL11, RpS2, and tra-2 led to reduced reproduction of Phytoseiulus persimilis.

Phytoseiulus persimilis is one of the most important biological control agents of spider mites. Multiple studies have been conducted on factors affecting its reproduction, but limited research on related molecular mechanisms has been carried out. In this study, RNA interference of three genes, ribosomal protein L11 (RpL11), ribosomal protein S2 (RpS2), and transformer-2 (tra-2), to newly emerged females were performed through oral delivery of double-stranded RNA, and knockdown of target genes was verified using qRT-PCR analysis. When RpL11 or RpS2 was interfered, 42 and 30% P. persimilis individuals either laid no egg or had no egg hatched, whereas the remaining females had their oviposition duration reduced by 31.8 and 49.9%, fecundity reduced by 48.1 and 67.8%, and egg hatching rate reduced by 20.4 and 22.4%, respectively. In addition, offspring sex ratios were significantly male biased especially at low fecundities. When tra-2 was interfered, no significant difference in fecundity was detected, but egg hatching rate reduced by 30.6%. This study verified the possibility of RNA interference in Phytoseiidae through oral delivery, and indicated that RpL11 and RpS2 are involved in egg formation, whereas tra-2 is involved in embryo development in P. persimilis. Phytoseiid mites have different sex determination pathways compared to insects. The present study provides data and evidence at molecular biological level for future research on reproduction and sex determination of phytoseiid mites.

Development and validation of nomogram models for predicting postoperative prognosis of early-stage laryngeal squamous cell carcinoma.

BACKGROUND: We aimed to investigate the postoperative prognosis in patients with early-stage laryngeal squamous cell carcinoma (LSCC) in association with the preoperative blood markers and clinicopathological characteristics and to develop nomograms for individual risk prediction. METHODS: The clinical data of 353 patients with confirmed early-stage LSCC between 2009 and 2018 were retrospectively retrieved from the First Affiliated Hospital with Nanjing Medical University. All patients were randomly divided into the training and testing groups in a 7:3 ratio. Univariate and multivariate analyses were performed, followed by the construction of nomograms to predict recurrence-free survival (RFS) and overall survival (OS). Finally, the nomograms were verified internally, and the predictive capability of the nomograms was evaluated and compared with that of tumour T staging. RESULTS: Univariate and multivariate analyses identified platelet counts (PLT), fibrinogen (FIB), and platelet to lymphocyte ratio (PLR) were independent factors for RFS, and FIB, systemic immune-inflammation index (SII), and haemoglobin (HGB) were independent prognostic factors for OS. The nomograms showed higher predictive C-indexes than T staging. Furthermore, decision curve analysis (DCA) revealed that the net benefit of the nomograms' calculation model was superior to that of T staging. CONCLUSIONS: We established and validated nomograms to predict postoperative 1-, 3- and 5-year RFS and OS in patients with early-stage LSCC based on significant blood markers and clinicopathological characteristics. These models might help clinicians make personalized treatment decisions.

Relationship between high density of peritumoral lymphatic vessels and biological behavior of cervical cancer.

OBJECTIVE: To investigate the relationship between lymphangiogenesis and lymphatic metastasis in cervical squamous carcinoma. METHODS: Eighty cases of invasive cervical squamous cancer were selected as objects of our study. Double immunohistochemical staining with antibodies against lymphatic vessel endothelial hyaluronan receptor 1 and Ki-67 was used to label the lymphatic vessels and mark the proliferative lymphatic vessels in cervical squamous cancer. The peritumoral lymphatic vessel density and intratumoral lymphatic vessel density was assessed. The lymphatic vessels proliferation index was evaluated by calculating Ki-67 proliferation index (PI) to reflect the lymphangiogenesis of cervical squamous cancer. Then the correlation between lymphangiogenesis and clinicopathologic features of cervical squamous cancer was analyzed. RESULTS: The LVD of cervical cancer (15.23 ± 3.6) was clearly higher than that of the adjacent normal cervical subepithelial tissues (9.9 ± 2.5, P < 0.001). The peritumoral lymphatic vessel density of cervical cancer (18.75 ± 4.3) was significantly higher than the intratumoral lymphatic vessel density of cervical cancer (11.71 ± 4.9, P < 0.001). Lymphatic PI (LPI) of cervical cancer (0.258 ± 0.07) was higher than that of the adjacent normal cervical subepithelial tissues (0.068 ± 0.08, P < 0.001). The peritumoral lymphatic vessel PI of cervical cancer (0.324 ± 0.06) was notably higher than the intratumoral lymphatic vessel PI of cervical cancer (0.232 ± 0.06, P < 0.001). Peritumoral lymphatic vessel density and peritumoral lymphatic vessel were clearly associated with the lymph node metastasis (P = 0.001 and P = 0.002, respectively) and lymphovascular space invasion (P = 0.024 and P = 0.01, respectively). CONCLUSIONS: The high density of peritumoral lymphatic vessels is a potential predictor of more aggressive phenotype of cervical squamous cancer.

An improved method for sensitive quantification of isoprenoid diphosphates in the astaxanthin-accumulating Haematococcus pluvialis.

A sensitive method has been established to simultaneously determine the concentrations of isopentenyl pyrophosphate (IPP), geranyl diphosphate (GPP), farnesyl diphosphate (FPP) and geranylgeranyl diphosphate (GGPP) in H. pluvialis under different environments. This method increased the extraction efficiency of isoprenoid diphosphates through releasing isoprenoid diphosphates using Tissue Lyser. This is the first report on the efficient extraction method of metabolites in H. pluvialis cells, being suitable for all algae and plants with thick cell wall. The concentrations of isoprenoid diphosphates were measured on poroshell EC-C18 column by UHPLC-MS/MS with the LODs of 0.015, 0.027, 0.022 and 0.076 pmol for DMAPP, GPP, FPP and GGPP, respectively. It is the most sensitive method for the determination of isoprenoid diphosphates in any sample to date. Using this method, the profile of isoprenoid diphosphates was analyzed and cisoid isomers of FPP and GGPP, (Z, Z)-FPP and (Z, Z, Z-GGPP) were found firstly in H. pluvialis.

Dilemma and promotion strategy of “dual channel”management policy for China’s medical insurance negotiated drugs / 中国药房

OBJECTIVE To provide reference for the smooth implementation of the “dual channel” management policy for China’s medical insurance negotiated drugs. METHODS Based on Smith policy implementation process model， the dilemmas for the implementation of “dual channel” policy for medical insurance negotiated drugs were analyzed from four aspects： implementation details and regulatory system， drug selection， drug provision and quality control， the situation of medical insurance funds and information technology capabilities. The corresponding promotion strategies were put forward. RESULTS & CONCLUSIONS The “dual channel” policy for medical insurance negotiated drugs in China might face implementation difficulties such as a lack of clear implementation rules and a full process supervision system， the suitability and operability of some medical insurance negotiated drugs need to be considered in the “dual channel” management， difficulties in drug allocation and quality control， differences in the management and operation of medical insurance funds in different regions， and insufficient informatization capability. In this regard， this study suggests that measures， such as improving the implementation rules of the “dual channel” policy， enhancing the rationality of the “dual channel” drug catalog， establishing a dynamic exit mechanism for “dual channel” pharmacies， promoting professional delivery services， and improving the electronic prescription circulation platform， which can be taken to enhance the implementation effect of the “dual channel” policy.

Spatial optimization mode of China's rural settlements based on quality-of-life theory.

This paper studies the optimization mode of the spatial organization of rural settlements based on the two-way interactive mechanism between the space of rural settlements and quality-of-life theory. It examines three main aspects: the integration of spatial function, the optimization of spatial structure, and the regulation of spatial scale. In this paper, we built an optimization mode and framework of spatial organization, called the road-oriented mode of rural settlements, based on quality-of-life theory. We systematically analyzed the mode's conceptual connotation, construction principles, frame, type, and spatial scale. At the same time, this paper realized the reasonable proportion and optimized combination of internal spatial type in settlements and focused on a reasonably sized scale of a single settlement and the distance scale between settlements. Our findings can be used as insight into the theoretical development of the spatial structure of rural areas. Results also provide a scientific basis for future spatial optimization and integration of rural settlements to improve quality of life.

Anti-glycation and anti-hardening effects of microencapsulated mulberry polyphenols in high-protein-sugar ball models through binding with some glycation sites of whey proteins.

Assembling between polyphenols and proteins has been freshly spotlighted. We studied the antiglycation and anti-hardening effects of microencapsulated mulberry polyphenols (MMPs) in a high-protein-sugar ball (HPSB) model during storage using multi-dimensional approaches, including UPLC-ESI-MS/MS, SDS-PAGE, MALDI-TOF-MS, FTIR, and a molecular docking study. It was found that MMPs significantly relegated the browning development, AGEs, and/or CML levels of HPSB after 45 d of storage at 45 °C. MMPs also downgraded the protein insolubility, aggregation, oligomerization, and glycoxidation during late-storage. A molecular docking scrutiny proved that cyanidin 3-O-rutinoside and quercetin 3-O-rutinoside interacted with whey proteins subunits via H-bonding and π-π interactions. This binding blocked some glycation residues of whey proteins especially lysyl residues, namely Lys5, 16, 60, 69, 93, 94, and 122. Our data disclosed that MMPs could be valorized as promising antiglycative ingredients to mitigate AGEs-generation and other subsequent unwanted changes in protein-rich food matrices.

Based on LC-MS technology explored the metabolomics of Agrimonia pilosa intervening in non-small cell lung cancer A549 cells / 药学学报

The objective of this study was to analyze the effects on cell viability, apoptosis, and cell cycle of non-small cell lung cancer (NSCLC) A549 cells after intervention with Agrimonia pilosa (AP) and investigate Agrimonia pilosa anti-tumor activity in vitro. Meanwhile, liquid chromatography mass spectrometry (LC-MS) metabolomics technology was used to analyze the changes of cellular metabolites and metabolic pathways. The results of this study will provide a theoretical and experimental basis for investigating the mechanism of the effect of Agrimonia pilosa on non-small cell lung cancer A549 cells. The results showed that the cell nucleus of A549 cells crumpled and apoptosis occurred with the increase of drug concentration. The survival rate of the cells decreased, and the inhibition rate reached 21.5% and 91.74% under the low and high dose conditions, respectively. Lactate dehydrogenase (LDH) content increased (P < 0.05). Metabolomics results showed significant differences in metabolism between groups, thirty-three distinct metabolites including LysoPC(24:0/0:0), LysoPC(17:0/0:0) and PC(O-40:5) were deduced. The pathway enrichment showed that the Agrimonia pilosa plays an anti-tumor role mainly by regulating the metabolism of glycerophosphate and purine in A549 cells, in which the effect on glycerophosphate metabolism pathway was most significant. The results of combined pharmacodynamics suggested that Agrimonia pilosa might induce apoptosis and inhibit the growth of A549 cells by regulating LysoPC(24:0/0:0), LysoPC(17:0/0:0) and PC(O-40:5) metabolites in A549 cells.

The availability, price and affordability of antidiabetic drugs in Hubei province, China.

Based on the high prevalence and undiagnosed rate of diabetes mellitus in China in recent years, the aim of this work was to evaluate the availability, price and affordability of pharmacotherapy for diabetes in public hospitals in Hubei province, China. In 2016, a cross-sectional survey was conducted using World Health Organization/Health Action International (WHO/HAI) methodology. Information on the availability and prices of 20 antidiabetic drugs was collected from 34 public hospitals representing three levels of care. Of the 20 antidiabetic drugs, 70.6% were below 50% availability. Total availability of the 20 drugs was higher in secondary and tertiary hospitals than in primary hospitals. All three hospital levels had higher availability of essential than non-essential antidiabetic medicines. The median markup ratios of originator brands (OBs) and lowest-price generics (LPGs) were 15.6% and 2.1%, respectively. The median potential saving ratio of using generics was 31.3%. Overall, the median affordability of 31 antidiabetic drugs ranged from 1.2 to 8.5 days of disposable income for residents with three income levels. After insurance reimbursement, the increase in the proportion of affordable drugs in urban and rural areas averaged 35.5% and 12.9%, respectively. The proportion of drugs with low availability and low affordability dropped from 54.8% to 38.7%. However, 41.7% of urban diabetic patients and 74.0% of rural diabetic patients remained unable to afford the drugs surveyed. Higher income and generic substitution are factors facilitating affordability. In Hubei province, the overall availability of 20 antidiabetic drugs was low, especially in primary hospitals. The affordability of most drugs surveyed was also low. Current health insurance can greatly improve affordability for urban residents with middle or high income. Policy changes should focus on the supply, pricing and clinical use of antidiabetic drugs and special health insurance plan for low income population with diabetes.

Characterization of Cell Subsets Associated With Prognosis of Osteosarcoma Based on Single-Cell Sequencing Data / 中国医学科学院学报

Objective To explore the cell subsets and characteristics related to the prognosis of osteosarcoma by analyzing the cellular composition of tumor tissue samples from different osteosarcoma patients.Methods The single-cell sequencing data and bulk sequencing data of different osteosarcoma patients were downloaded.We extracted the information of cell samples for dimensionality reduction,annotation,and cell function analysis,so as to identify the cell subsets and clarify the cell characteristics related to the prognosis of osteosarcoma.The development trajectory of macrophages with prognostic significance was analyzed,and the prognostic model of osteosarcoma was established based on the differentially expressed genes of macrophage differentiation.Results The cellular composition presented heterogeneity in the patients with osteosarcoma.The infiltration of mononuclear phagocytes in osteosarcoma had prognostic significance(P=0.003).Four macrophage subsets were associated with prognosis,and their signature transcription factors included RUNX3(+),ETS1(+),HOXD11(+),ZNF281(+),and PRRX1(+).Prog_Macro2 and Prog_Macro4 were located at the end of the developmental trajectory,and the prognostic ability of macrophage subsets increased with the progression of osteosarcoma.The prognostic model established based on the differentially expressed genes involved in macrophage differentiation can distinguish the survival rate of osteosarcoma patients with different risks(P<0.001).Conclusion Macrophage subsets are closely related to the prognosis of osteosarcoma and can be used as the key target cells for the immunotherapy of osteosarcoma.

Association between appendicular skeletal muscle mass and ankle-brachial index in patients with type 2 diabetes / 中华健康管理学杂志

Objective:To assess the relationship between appendicular skeletal muscle mass (ASM) and ankle brachial index (ABI) among patients with type 2 diabetes.Methods:In this cross-sectional study, from July 2018 to March 2019, a total of 278 patients with type 2 diabetes treated in Zhongda Hospital were enrolled in this study, and there were 158 males and 120 females. General information and clinical biochemical parameters and ABI in the patients were collected. The appendicular muscle mass was quantitatively measured with body composition analyzer to achieve ASM. And the appendicular skeletal muscle mass index (ASMI), skeletal muscle index (SMI), and appendicular skeletal muscle mass/body mass index (ASM/BMI) were calculated respectively. Correlation analysis and multiple linear regression analyses with different adjustment models were conducted to analyze the correlation between ABI and above-mentioned indexes.Results:The Pearson correlation analysis showed that ABI had significant positive correlation with ASM, ASMI and ASM/BMI ( r=0.14, 0.13, 0.13, all P<0.05), but a marginal relation with SMI ( r=0.116, P=0.053). Multiple linear regression analysis suggested that ASMI ( β=0.053, 95% CI: 0.006-0.101, P=0.027) and AMI/ABI ( β=0.347, 95% CI: 0.040-0.654, P=0.027) were significantly related to ABI. Conclusion:ASM is positively associated with ABI in patients with type 2 diabetes.

Survey on nutrition awareness and its influencing factors among parents of preschool children / 中华全科医师杂志

Objective:To survey the awareness status and its influencing factors among parents of preschool children.Methods:Data was collected from the National Nutrition and Health Systematic Survey for 0-18 Year Children in China. A total of 2 625 children aged 3-5 years and their parents living in northern and southern regions of China were randomly selected by multi-stage stratified cluster sampling. The physical measurements were performed for the children, including height and weight; and the body mass index (BMI) and age-for-BMI Z-score (BAZ) were calculated. The questionnaire survey was conducted for the parents, including the demographic characteristics of parents and their children, the perception of their child′s nutritional status (overweight/obesity, normal, wasting) etc. According to WHO standards, the nutritional status of the children was classified as wasting, normal and overweight/obesity. The awareness of parents on their children′s nutritional status was classified as underestimated, correct, overestimated and unclear. Parents′ inability to correctly judge children′s nutritional status was defined as cognitive bias, including underestimation bias and overestimation bias. Multivariate logistic regression model was used to analyze the influencing factors of parents′ underestimation or overestimation of children′s nutritional status.Results:Among 2 625 enrolled preschool children, there were 1 312 boys (50.0%) and 1 313 girls (50.0%); and 648 (24.7%), 944 (36.0%) and 1 033 (39.3%) children aged 3, 4 and 5 years, respectively. One parent (mother, farther or others) of each child was selected for survey, and most of them were mothers (1 998(76.1%)). The prevalence rate of overweight/obesity and wasting was 10.3% (270/2 625) and 1.4% (38/2 625), respectively; and 2 317 children (88.3%) were normal. Among all parents surveyed, 1 766 (67.3%) were correct about their children′s nutritional status (correct group), 612 (23.3%) underestimated their children′s nutritional status (underestimated group), 213 (8.1%) overestimated their children′s nutritional status (overestimated group) and 34 (1.3%) were not aware of their children′s nutritional status (unclear group). The multivariate logistic regression analysis showed that girls ( OR=0.817, 95% CI: 0.678-0.984), living in rural areas ( OR=0.801, 95% CI: 0.662-0.969), large birth weight of child ( OR=0.639, 95% CI: 0.420-0.970) were protective factors for parents underestimating children′s nutritional status. Living in the northern region ( OR=1.698, 95% CI: 1.260-2.290), large birth weight of children ( OR=1.826, 95% CI: 1.149-2.902), father with overweight/obesity ( OR=1.467, 95% CI: 1.089-1.977) and maternal overweight/obesity ( OR=1.778, 95% CI: 1.308-2.417) were the risk factors for parents to overestimate the nutritional status of children. Conclusions:The survey shows that parents of preschool children have a relatively high cognitive bias on the nutritional status of their children. Parents of girls, living in rural areas or having child with large birth weight are less likely to underestimate the nutritional status of children; parents living in northern regions, having a child with large birth weight, or with overweight/obese are likely to overestimate the nutritional status of children.

Xiaotan Sanjie recipe, a compound Chinese herbal medicine, inhibits gastric cancer metastasis by regulating GnT-V-mediated E-cadherin glycosylation / 中西医结合学报

OBJECTIVE@#Xiaotan Sanjie recipe (XTSJ), a Chinese herbal compound medicine, exerts a significant inhibitory effect on gastric cancer (GC) metastasis. This work investigated the mechanism underlying the XTSJ-mediated inhibition of GC metastasis.@*METHODS@#The effect of XTSJ on GC metastasis and the associated mechanism were investigated in vitro, using GC cell lines, and in vivo, using a GC mouse model, by focusing on the expression of Glc-N-Ac-transferase V (GnT-V; encoded by MGAT5).@*RESULTS@#The migration and invasion ability of GC cells decreased significantly after XTSJ administration, which confirmed the efficacy of XTSJ in treating GC in vitro. XTSJ increased the accumulation of E-cadherin at junctions between GC cells, which was reversed by MGAT5 overexpression. XTSJ administration and MGAT5 knockdown alleviated the structural abnormality of the cell-cell junctions, while MGAT5 overexpression had the opposite effect. MGAT5 knockdown and XTSJ treatment also significantly increased the accumulation of proteins associated with the E-cadherin-mediated adherens junction complex. Furthermore, the expression of MGAT5 was significantly lower in the lungs of BGC-823-MGAT5 + XTSJ mice than in those of BGC-823-MGAT5 + solvent mice, indicating that the ability of gastric tumors to metastasize to the lung was decreased in vivo following XTSJ treatment.@*CONCLUSION@#XTSJ prevented GC metastasis by inhibiting the GnT-V-mediated E-cadherin glycosylation and promoting the E-cadherin accumulation at cell-cell junctions.

AIM:To investigate the effect of 3% diquafosol sodium eye drops combined with intense pulsed light on the treatment of meibomian gland dysfunction and the change of meibomian glands.METHODS: Prospective study. A total of 141 patients(282 eyes)who were diagnosed with meibomian gland dysfunction from January 2021 to May 2022 in our hospital were selected and they were randomly divided into the control group(73 cases, 146 eyes)and the observation group(68 cases, 136 eyes)according to random number table. The control group was given 0.3% sodium hyaluronate eye drops combined with intense pulsed light, and the observation group was treated with 3% diquafosol sodium eye drops combined with intense pulsed light. The subjective symptom score, physical sign score, non-invasive tear break-up time, tear meniscus height, lipid layer thickness, and meibomian gland density before and after the treatment were compared between the two groups at 2wk after the end of treatment.RESULTS: There were no differences in the subjective symptom score, physical sign score, non-invasive tear break-up time, tear meniscus height, lipid layer thickness, and meibomian gland density between the two groups of patients before treatment(P&#x003E;0.05). After 2wk of treatment, the symptom scores and physical sign scores of patients in the two groups continued to decrease, non-invasive tear break-up time and lipid layer thickness continued to increase, and the meibomian gland density also increased. The tear meniscus height in the observation group increased, while the control group showed no significant changes. The observation group had better clinical indicators than the control group(P&#x003C;0.05). No obvious complications were observed in all patients.CONCLUSION: The combination of diquafosol sodium eye drops and intense pulsed light is synergistic in the treatment of meibomian gland dysfunction, with significant therapeutic effects and improvement of meibomian gland repair, which is significantly superior to simple intense pulsed light therapy.

OBJECTIVE: To investigate the status of Oncomelania hupensis snails in Anhui Province in 2016, so as to provide the evidence for formulating the 13th Five-Year Plans for Schistosomiasis Control. METHODS: In 2016, a snail survey was conducted in Anhui Province according to the National Programme of the Oncomelania Snail Survey, covering all snail habitats or historical snail habitats and suspected environments of snail breeding, and the results of the survey were analyzed. RESULTS: In 2016, 22 848 environments were surveyed, and no schistosome-infected snails were found. There were 17 927 historical snail habitats in whole province, among which, the environments without changes, changed partly and changed completely accounted for 71.2%, 19.3% and 9.5%, respectively. The area of historical snail habitats was 1.410 billion m2. There were 4 830 environments with snail habitats covering an area of 0.265 billion m2 in 38 counties of 7 cities, including newly emerging area of 1 287.65 hm2 and reemerging area of 1 375.32 hm2. The density of living snails was 0.392 0 snails/0.1 m2, and the rate of frame with living snails was 12.93%. The type of marshland and lake regions, and the type of hilly and mountainous regions accounted for 22.4% and 77.6% of number of snail habitats, and accounted for 86.7% and 13.3% of areas of snail habitats, respectively. Among the different types of vegetation in snail habitats, grass was superior owe to accounting for 82.2% of the number of snail habitats, 57.3% of the area with snail habitats, and the highest density of living snails (0.413 9 snails/0.1 m2). Among the different types of environments in snail habitats, the ditch was superior owe to accounting for 56.8% of the number of snail habitats, the highest density of living snails (0.570 3 snails/0.1m2) and the highest rate of frame with living snails (18.57%), and the beach was superior owe to accounting for 87.8% of the area with snail habitats. In Anhui Province, the first year of snails and schistosome-infected snails being found was 1950 and 1952, respectively, and the latest year of schistosome-infected snails being found was 2012. The map showed that the most environments with snail habitats were distributed along the Yangtze River in Anhui Province. CONCLUSIONS: For the first time, the investigation has built the database and map of snail spatial distribution, which truly reflect the historic and current status of snail distribution in Anhui Province and can provide the evidence for formulating the 13th Five-Year Plans for Schistosomiasis Control and improving the schistosomiasis prevention and control work in the future.
