ABSTRACT

Objective: To evaluate the effectiveness of therapeutic massage (tuina) for treating knee osteoarthritis (KOA). Methods: Six English and Chinese databases, including Chinese National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), Cochrane Library and PubMed databases, were independently searched to identify appropriate randomized controlled trials (RCTs) studying therapeutic massage for KOA compared to oral non-steroidal anti-inflammatory drugs (NSAIDs) alone. The main outcome measures were total effectiveness and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score. Results: A total of 8 RCTs were included and they were of average quality. The results showed that therapeutic massage was more effective than NSAIDs comparing total effectiveness [risk ratio (RR)=1.14, 95% confidence interval (CI) (1.07, 1.21), P<0.0001]; compared with NSAIDs, therapeutic massage produced more significant improvements in pain [mean difference (MD)=-2.06, 95%CI (-2.75, -1.36), P<0.00001], stiffness intensity [MD=-0.90, 95%CI (-1.05, -0.75), P<0.00001] and joint function [MD=-12.48, 95%CI (-13.91, -11.05), P<0.00001]. Conclusion: Therapeutic massage was more effective than oral NSAIDs in treating KOA. In relieving pain and stiffness and improving the function of knee joint, therapeutic massage was superior to NSAIDs.

ABSTRACT

According to Chinese medicine, the atlantoaxial joint is a composite joint composed of tendons and bones, and the stability of the joint depends on the 'tendon-bone balance' involving tendons, ligaments, atlas and axis. Multiple causes of 'tendon off-position, joint subluxation' will lead to joint 'tendon-bone imbalance', which will evolve into atlantoaxial subluxation (AAS), endangering human health. Chinese therapeutic massage (tuina) is a very effective treatment for AAS in adults, but conventional manipulations are prone to ineffectiveness or accidents due to neglect of the causal relationship of the 'tendon-bone imbalance' and inappropriate manipulations. Compared with conventional manipulations, the rational choice of modified manipulations under the guidance of 'tendon-bone balance' theory is more effective and less risky, and more worthy of clinical promotion. From the 'tendon-bone balance' theory, we considered the shortcomings of conventional manipulations, and introduced several modified manipulations that have their own strengths in 'tendon smoothing' and 'bone setting', in order to provide new ideas for treatment of AAS in adults.

ABSTRACT

OBJECTIVE Human metapneumovirus (hMPV) is semblable to respiratory syncytial virus (RSV) which causes respiratory infections typically characterized by cough, runny nose, fever, and nasal congestion but sometimes progressing to bronchiolitis and pneumonia. Whereas, there is no corresponding drug to inhabit the virus. Studies of new compounds with potential anti-HMPV activity could produce clinical value. Chinese herbal medicine played a great role during COVID-19, therefore we choose some small molecular (JH001) extracted from botany to investigate therapeutic effect on hMPV and the underlying mechanisms. METHODS In this study, 16HBE cells were used as a model to explore in vitro antiviral effect. Cytotoxicity assays were performed before the antiviral tests, cell viability of 16HBE cells handled by different concentration of JH001 was estimated by Cell Counting Kit-8 (CCK-8). Then RT-qPCR, immunofluores?cence, and flow cytometer were used to test the viral titer after cells infected with hMPV. Eventually, 6-8 weeks mice were infected intranasally with 60 μL of hMPV, the control group was treated with 0.9% saline water, other groups were administered with JH001 and ribavirin, then the lung virus titer and protective effect in lung were judged. RESULTS The obtained JH001 exhibited no cytotoxicity to 16HBE cells during 6.25 - 200 μmol · L-1. RT-QPCR demonstrated that JH001 showed obvious inhabitation to the viral replication and showed great significance compared with saline. And fluo?rescence exhibited distinct decrease of hMPV-N protein, flow cytometer results showed that MFI decrease evidently. Sig?nificant reduction of N-gene expression was observed in those mice treated with JH001 compared with saline group, which indicated that JH001 probably had protective and therapeutic effect on viral replication. CONCLUSION This study illustrated that JH001 might be a promising option for small molecular against hMPV and JH001 might be worthy of fur?ther development and used as a potential therapeutic strategy for other respiratory viruses in the future.

ABSTRACT

An ultra-high performance liquid chromatography method for the determination of 8 constituents in Qingzao Jiufei Decoction was established and the basis of related chemical substances with antioxidant activity in Qingzao Jiufei Decoction was explored. The separation was performed on a Waters Cortecs RP Shield C18 (150 mm × 2.1 mm, 1.6 μm) using UHPLC-DAD as the mobile phase was water (containing 0.1% phosphoric acid) – acetonitrile with flow rate of 0.30 mL·min-1 by gradient elution ① determining 5 constituents (amygdalin, liquiritin, liquiritin apioside, rutin and isoquercitrin) at the wavelength of 210 nm, 237 nm and 358 nm. Under gradient elution ②, 3 constituents (glycyrrhizin, glycyrrhizic acid and sesamin) were determined at the wavelength of 210 nm and 265 nm. The IC50 of 10 batches of Qingzao Jiufei Decoction scavenging 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS+) free radicals obtained through test and Probit model was analyzed for correlation with the contents of 8 constituents. The established methods had a good linear relationship (r > 0.999), good repeatability and stability. The recovery rate was between 82.8% and 112.4%. In a series of concentration range, the higher the concentration of Qingzao Jiufei Decoction, the stronger the free radical scavenging effect. There was a significant correlation between the content of rutin and glycyrrhizic acid and the IC50 of scavenging free radicals. The content determination methods established in this experiment provide a basis for a reasonable and scientific evaluation of the quality of Qingzao Jiufei Decoction. Qingzao Jiufei Decoction has antioxidant activity, which is significantly positively correlated with the content of rutin and glycyrrhizic acid.

ABSTRACT

Objective:To explore the feasibility of replacing wood (or wood chips) with crop residues for culturing <italic>Armillaria gallica</italic> targeting the problems of forest resource destruction and increased cultivation cost caused by the extensive use of wood in <italic>Gastrodia elata</italic> cultivation, so as to reduce the cultivation cost of <italic>G. elata</italic>, promote the effective use of crop residues, and protect forest resources. Method:The growth situation of <italic>A. gallica</italic> in different media was observed, followed by the measurement of its growth rate using streaking method and the determination of total polysaccharide content of <italic>A. gallica</italic> by phenol-concentrated sulfuric acid colorimetric method. In order to further optimize the soybean straw cultivation medium, we carried out a four-factor three-level L<sub>9</sub>(3<sup>4</sup>) orthogonal assay on the ratio of main ingredients, sucrose content, inorganic salt content, and water content. Result:The comparison of growing states of <italic>A. gallica</italic> cultured in different media revealed that <italic>A. gallica</italic> in soybean straw medium began to grow since the fourth day of inoculation, and the mycelium grew well, with the growth rate being 0.352 cm·d<sup>-1</sup>, which was 1.48 times that in birch wood medium. The total polysaccharide content of <italic>A. gallica</italic> cultured in soybean straw medium was the highest, which was 39.260 mg·g<sup>-1</sup>, much higher than 17.028 mg·g<sup>-1</sup> of that cultured in birch wood medium. This demonstrated the obvious advantage of soybean straw medium, whose main ingredients were soybean straw and wheat bran at the ratio of 8:2, with the sucrose and inorganic salt content accounting for 1% and 0.5% of the main ingredients, respectively. When the water content reached 50%, the growth rate of <italic>A. gallica</italic> was maintained at 0.392 cm·d<sup>-1</sup>. Conclusion:This study has provided a basis for utilizing soybean straw instead of wood (or wood chips) as cultivation medium for <italic>A. gallica</italic>, thus better reducing the waste of forest resources and protecting the natural environment in the cultivation of <italic>G. elata</italic>.

ABSTRACT

Taohong Siwutang, originating from Fuke Bingjian by CHAI Dehua in the Qing Dynasty, has been included in the first batch of the 100 classical prescriptions published by the National Administration of Traditional Chinese Medicine(TCM). Taohong Siwutang is composed of six Chinese medicinals, namely the wine-washed Angelicae Sinensis Radix, wine-washed Rehmanniae Recens Radix, wine-washed Carthami Flos, wine-processed Paeoniae Alba Radix, Persicae Semen undergoing peel-off process in hot water, and Chuanxiong Rhizoma, possessing the effects of nourishing blood, promoting blood circulation, and removing blood stasis, and it is mainly applicable to patients with blood deficiency and stasis syndrome. The textual research on the key information of classical prescriptions and the summarization of their ancient and modern applications are conducive to learning about the research status and confirming the subsequent research direction, thus better guiding the preparation of substance benchmarks and the in-depth exploration of preparations. By exploring the sources and historic evolution of Taohong Siwutang and each Chinese medicinal, this paper uncovered the prescription composition, origin of each Chinese medicinal, processing method, and prescription dose. The review of its clinical applications showed that the application scope in modern times has been extended and expanded in contrast to that recorded in ancient books. As revealed by the clinical application literature, it has been mainly employed for treating gynecological diseases such as dysmenorrhea and irregular menstruation, orthopedic diseases like fracture, dermatological diseases such as chloasma, and internal diseases such as coronary heart disease, all of which were differentiated into the blood deficiency and stasis syndrome. It could be seen that Taohong Siwutang had great clinical application value. This review of the ancient and modern literature concerned with Taohong Siwutang and the analysis and determination of its key information are expected to provide a reference for the rational clinical application and further research of Taohong Siwutang.

ABSTRACT

Objective:To explore the acute toxicities and hepatotoxicities of aqueous extracts of Taxilli Herba from <italic>Morus alba</italic>, <italic>Toxicodendron</italic> <italic>trichocarpum</italic>, <italic>Camellia oleifera</italic>, <italic>Salix babylonica</italic>, <italic>Melia azedarach</italic>, and <italic>Nerium indicum</italic> against zebrafish model and the effect of different hosts on the toxicity of Taxilli Herba, hoping to provide a theoretical basis for the safe use of Taxilli Herba. Method:The normally developed AB zebrafish at 3-day post fertilization was selected for acute toxicity study. According to the results of preliminary toxicity experiments, the zebrafishes were treated with aqueous extracts of Taxilli Herba from different hosts at six doses, and their mortality was calculated 72 h later. GraphPad Prism 6.0 was used for plotting the dose-toxicity curve, followed by the calculation of their median lethal concentration (LC<sub>50</sub>) and 10% lethal concentration (LC<sub>10</sub>). The gz15Tg/+(AB) liver fluorescent protein transgenic zebrafish with normal development at 4-day post fertilization was applied for the hepatotoxicity study. The zebrafishes were divided into the low-, medium-, and high-dose groups of aqueous extracts of Taxilli Herba from six hosts, the positive control (acetaminophen) group, and the blank (embryo amniotic fluid) group, and then treated with the corresponding drugs. Seventy-two hours later, the liver morphology and fluorescent area changes in zebrafish were observed. And the activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected. Result:The results of acute toxicity test demonstrated that the LC<sub>50</sub> values of water extracts of Taxilli Herba from <italic>M. alba</italic>, <italic>T.</italic> <italic>trichocarpum</italic>, <italic>C. oleifera</italic>, <italic>S. babylonica</italic>, <italic>M. azedarach</italic>, and <italic>N. indicum</italic> were 1.24, 0.94, 0.51, 0.38, 0.11, 0.09 g·L<sup>-1</sup>, respectively, and the LC<sub>10</sub> values were 0.70, 0.60, 0.35, 0.28, 0.08, 0.07 g·L<sup>-1</sup>, respectively. As revealed by hepatotoxicity test, compared with the blank group, the positive control group exhibited liver morphological changes, decreased fluorescent area (<italic>P</italic><0.01), and elevated ALT and AST activities (<italic>P</italic>< 0.01), suggesting that acetaminophen was hepatotoxic to zebrafish. However, there was no change in the liver morphology or fluorescent area of zebrafish in the low-, medium-, and high-dose groups of water extracts of Taxilli Herba from <italic>M. alba</italic>, and the ALT and AST activities were decreased. By contrast, the liver morphology and fluorescent areas in the medium- and high-dose groups of water extracts of Taxilli Herba from <italic>T.</italic> <italic>trichocarpum</italic>, <italic>C. oleifera</italic>, <italic>S. babylonica</italic>, <italic>M. azedarach</italic>, and <italic>N. indicum</italic> changed to varying degrees (<italic>P</italic><0.05, <italic>P</italic><0.01). Besides, the activities of both ALT and AST were also enhanced. These indicated that Taxilli Herba from <italic>M. alba</italic> had no hepatotoxicity to zebrafish, while that from <italic>T.</italic> <italic>trichocarpum</italic>, <italic>C. oleifera</italic>, <italic>S. babylonica</italic>, <italic>M. azedarach</italic>, and <italic>N. indicum</italic> showed varying degrees of hepatotoxicity to zebrafish. Conclusion:The toxicity of Taxilli Herba is host-dependent. Taxilli Herba from <italic>M. alba</italic> has no hepatotoxicity, but that from the other five hosts shows varying degrees of hepatotoxicity. Standardizing the host source may be an important measure to realize the medication safety of Taxilli Herba.

ABSTRACT

Objective:To select and evaluate new Chinese herbal prescription for the treatment of decreased ovarian reserve (DOR) and its appropriate dosage. Method:The literature concerning the treatment of DOR with traditional Chinese medicine (TCM) was retrieved from such databases as Chinese Journal Full-text Database, Wanfang Data Knowledge Service Platform, and Chongqing Weipu Database for Chinese Technical Periodicals (VIP), based on which a database was established using the Traditional Chinese Medicine Inheritance Support System (TCMISS) V2.5. The data mining was then carried out to obtain the core combinations of Chinese herbs and new Chinese herbal prescription combinations, followed by the determination of the new Chinese herbal prescription by expert group discussion for experiment evaluation. The female SD rats were divided into the normal group, DOR model group, Kuntai capsule group, and low-, medium-, and high-dose new Chinese herbal prescription groups, with 12 rats in each group. Rats in the Kuntai capsule group and low-, medium-, and high-dose new Chinese herbal prescription groups were treated with Kuntai capsule solution (0.5 g·kg<sup>-1</sup> determined according to the dosage in the instruction) and 3.037 5, 6.075, and 9.12 g·kg<sup>-1</sup> new Chinese herbal prescription, respectively. After 21 days, the estrous cycle was observed by vaginal exfoliated cell smear, and the ovarian structure was observed by hematoxylin-eosin (HE) staining. The serum anti-mullerian hormone (AMH), follicle stimulating hormone (FSH), luteinizing hormone (LH), and estrogen (E<sub>2</sub>) contents as well as the reactive oxygen species (ROS), malondialdehyde (MDA), and glutathione (GSH) levels and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities in ovary were detected using biochemical methods. Result:The new Chinese herbal prescription subjected to experimental evaluation was composed of 11 Chinese herbs, namely Rehmanniae Radix Praeparata 20 g, Cervi Cornus Colla 12 g, Lycii Fructus 20 g, Corni Fructus 12 g, Albiziae Cortex 9 g, Nelumbinis Plumula 3 g, Salviae Miltiorrhizae Radix et Rhizoma 20 g, Astragali Radix 30 g, Atractylodis Macrocephalae Rhizoma 12 g, Dioscoreae Rhizoma 30 g, and Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle 6 g. Compared with the model group, the Kuntai capsule group and medium- and high-dose new Chinese herbal prescription groups exhibited significantly improved estrous cycle and follicular development, elevated serum AMH and E<sub>2</sub> and ovarian GSH (<italic>P</italic><0.05), decreased serum FSH and LH (<italic>P</italic><0.05) and ovarian ROS and MDA (<italic>P</italic><0.05), and enhanced SOD, CAT, and GSH-Px activities (<italic>P</italic><0.05). There were no significant differences in the above-mentioned indexes between the Kuntai capsule group and the middle- and high-dose new Chinese herbal prescription groups, but the estrous cycle and follicular development were better in the latter two groups. Conclusion:The new Chinese herbal prescription screened by data mining is able to enhance ovarian antioxidation, promote follicular development, ameliorate serum hormone and estrous cycle, and effectively improve ovarian reserve function in DOR rats. The medium dose (6.075 g·kg<sup>-1</sup>) has been proved optimal.

ABSTRACT

Objective To investigate the changes of mitochondrial metabolic functions of macrophages following Echinococcus multilocularis infections, so as to provide insights into the pathogenesis of alveolar echinococcosis. Methods Two groups were assigned according to different treatment methods. In the culture group, mouse leukemic monocyte macrophage RAW264.7 cells were cultured with 2 000 E. multilocularis at a ratio of 500∶1, while RAW264.7 cells in the control group were given no treatment. Then, both the culture and control groups were further divided into the 24 h and 72 h subgroups. Mitochondria were stained with MitoTracker® Deep Red FM and the mean fluorescence intensity of macrophage mitochondria was measured with the Cytation 5 Cell Imaging Multi-Mode Reader. The mitochondrial DNA copy number was quantified using the quantitative real-time PCR (qPCR) assay, and the mitochondrial energy metabolism was monitored using the Seahorse XF assay. In addition, the mitochondrial reactive oxygen species and mitochondrial membrane potential were detected using flow cytometry. Results The mean fluorescence intensities of macrophage mitochondria were significantly lower in the 24 h (15 341 ± 2 532 vs. 17 823 ± 3 429; t = 6.379, P < 0.01) and 72 h (18 102 ± 3 505 vs. 21 511 ± 5 144; t = 17.680, P < 0.01) culture subgroups than in the corresponding control subgroups, and lower mitochondrial DNA copy numbers were measured in the 72 h culture subgroup than in the 72 h control group [(3.23 × 109 ± 1.78 × 107) vs. (4.39 × 109 ± 3.70 × 107); t = 8.85, P < 0.001]. The oxygen consumption rates were significantly greater in the 24 h [(241.70 ± 73.13) pmol/min vs. (69.05 ± 52.30) pmol/min; t = 7.89, P < 0.01] and 48 h culture groups [(249.50 ± 42.06) pmol/min vs. (60.28 ± 40.66) pmol/min; t = 8.64, P < 0.01] than in the corresponding control groups, and a higher extracellular acidification rate was seen in the 48 h culture group than in the 48 h control group ([ 111.6 ± 17.49) mpH/min vs. (35.05 ± 7.57) mpH/min; t = 16.90, P < 0.01]. In addition, flow cytometry detected higher mean fluorescence intensity of mitochondrial reactive oxygen species (58 264 ± 10 087 vs. 4 307 ± 97; t = 12.930, P < 0.01) and lower mitochondrial membrane potential (9.833% ± 2.285% vs. 2.667% ± 0.208%; t = 6.645, P < 0.01) in the 72 h culture group than in the control group. Conclusions E. multilocularis infection may impair mitochondrial functions and inhibit oxidative phosphorylation of macrophages, resulting in increased macrophage glycolysis. It is speculated that the alteration of macrophage metabolic states may contribute to the mechanisms underlying the development and progression of alveolar echinococcosis.

Objective To establish a nucleic acid assay for detection of Paragonimus skrjabini based on the recombinase-aided isothermal amplification (RAA) technique, and to preliminarily evaluate its detection efficiency. Methods The metacercariae of P. skrjabini, P. westermani and Euparagonimus cenocopiosus were isolated from crabs, and genomic DNA was extracted for molecular characterization. The cytochrome coxidase 1 (cox1) gene sequence of P. skrjabini was selected as the target gene fragment, and the primers and probes were designed, screened and synthesized for RAA assay. The genomic DNA of P. skrjabini metacercariae from Jiyuan City and Yiyang County of Luoyang City, Henan Province were used as templates for verification of the fluorescent RAA assay. The fluorescent RAA assay was performed to detect different concentrations of plasmids containing target gene fragment and P. skrjabini metacercariae genomic DNA to determine the sensitivity. Fluorescent RAA assay was performed with recombinant plasmids containing P. skrjabini cox1 gene sequences at different concentrations and P. skrjabini genomic DNA as templates to evaluate its sensitivity, and the genomic DNA of P. westermani, E. cenocopiosus, Clonorchis sinensis and Schistosoma japonicum was detected with fluorescent RAA assay to evaluate its specificity. Results P. skrjabini, P. westermani and E. cenocopiosus metacercariae were isolated from crabs, respectively. Molecular characterization and phylogenetic analysis confirmed their homology with the genes sequences of standard Paragonimus strains in GenBank. A fluorescent RAA assay was successfully established for nucleic acid detection of P. skrjabini, and the genomic DNA of P. skrjabini metacercariae from Jiyuan City and Yiyang County of Luoyang City, Henan Province was amplified using the fluorescent RAA assay within 5 min, while the negative control was not amplified. If the recombinant plasmid containing P. skrjabini cox1 gene sequences was used as templates, the fluorescent RAA assay showed the lowest detection limit of 10 copies/μL, and positive amplification was observed within 5 min. If genomic DNA was used as templates, the fluorescent RAA assay showed the lowest detection limit of 10 pg/μL, and all positive amplifications were found within 5 to 10 min. In addition, the fluorescent RAA assay was tested negative for P. westermani, E. cenocopiosus, C. sinensis and S. japonicum. Conclusions A rapid, sensitive and specific fluorescent RAA assay is successfully established for nucleic acid detection of P. skrjabini, which has potential values in rapid field detection and species identification in freshwater crabs in areas endemic for P. skrjabini.

ABSTRACT

BACKGROUND@#Prenatal evaluation of fetal lung maturity (FLM) is a challenge, and an effective non-invasive method for prenatal assessment of FLM is needed. The study aimed to establish a normal fetal lung gestational age (GA) grading model based on deep learning (DL) algorithms, validate the effectiveness of the model, and explore the potential value of DL algorithms in assessing FLM.@*METHODS@#A total of 7013 ultrasound images obtained from 1023 normal pregnancies between 20 and 41 + 6 weeks were analyzed in this study. There were no pregnancy-related complications that affected fetal lung development, and all infants were born without neonatal respiratory diseases. The images were divided into three classes based on the gestational week: class I: 20 to 29 + 6 weeks, class II: 30 to 36 + 6 weeks, and class III: 37 to 41 + 6 weeks. There were 3323, 2142, and 1548 images in each class, respectively. First, we performed a pre-processing algorithm to remove irrelevant information from each image. Then, a convolutional neural network was designed to identify different categories of fetal lung ultrasound images. Finally, we used ten-fold cross-validation to validate the performance of our model. This new machine learning algorithm automatically extracted and classified lung ultrasound image information related to GA. This was used to establish a grading model. The performance of the grading model was assessed using accuracy, sensitivity, specificity, and receiver operating characteristic curves.@*RESULTS@#A normal fetal lung GA grading model was established and validated. The sensitivity of each class in the independent test set was 91.7%, 69.8%, and 86.4%, respectively. The specificity of each class in the independent test set was 76.8%, 90.0%, and 83.1%, respectively. The total accuracy was 83.8%. The area under the curve (AUC) of each class was 0.982, 0.907, and 0.960, respectively. The micro-average AUC was 0.957, and the macro-average AUC was 0.949.@*CONCLUSIONS@#The normal fetal lung GA grading model could accurately identify ultrasound images of the fetal lung at different GAs, which can be used to identify cases of abnormal lung development due to gestational diseases and evaluate lung maturity after antenatal corticosteroid therapy. The results indicate that DL algorithms can be used as a non-invasive method to predict FLM.

ABSTRACT

BACKGROUND@#Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China.@*METHODS@#The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD.@*RESULTS@#A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05).@*CONCLUSION@#Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

ABSTRACT

The paper aims to establish the method to determine the monosaccharide composition and monosaccharide ratio in propylene glycol alginate sodium sulphate (PSS). Samples were hydrolyzed with trifluoroacetic acid, neutralized with sodium hydroxide solution after the reaction conditions for sample pretreatment were optimized via orthogonal analysis. A high performance anion exchange chromatograghy (HPAEC) coupled with pulsed amperometric detector (PAD) was performed on a CarboPac®PA20, using 200 mmol·L-1 sodium hydroxide solution and 1 mol·L-1 sodium acetate solution as mobile phase. The established HPAEC-PAD method was validated by testing the linear relationship, precision and accuracy, and showed exclusive, sensitive, rapid and wide use. The monosaccharide composition of PSS from different manufacture can be accurately determined with great significance for the structural identification of PSS.

ABSTRACT

Objective To investigate the current distribution of ticks and predict the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2017, so as to provide insights into tick control and management of tick-borne diseases in these areas. Methods All publications pertaining to tick and pathogen distribution in the Yangtze River Delta urban agglomeration were retrieved, and the geographical location of tick distribution was extracted. The effects of 19 climatic factors on the distribution of ticks were examined using the jackknife method, including the mean temperature of the wettest quarter, precipitation of the coldest quarter, mean temperature of the driest quarter, maximum temperature of the warmest month, precipitation of the driest month, minimal temperature of the coldest month, annual precipitation, mean daily temperature range, precipitation seasonality, annual temperature range, temperature seasonality, annual mean temperature, mean temperature of the warmest quarter, precipitation of the wettest quarter, isothermality, mean temperature of the coldest quarter, precipitation of the wettest month, precipitation of the driest quarter and precipitation of the warmest quarter. The distribution of ticks was analyzed in 2020 using the maximum entropy (MaxEnt) model, and the potential suitable habitats of ticks were predicted in 2070 using the MaxEnt model based on climatic data. Results A total of 380 Chinese and English literatures were retrieved, and 148 tick distribution sites were extracted, with 135 sites included in the subsequent analysis. There were 7 genera (Haemaphysalis, Rhipicephalus, Ixodes, Dermacentor, Boophilus, Hyalomma and Amblyomma) and 27 species of ticks detected in the Yangtze River Delta urban agglomeration. The climatic factors affecting the distribution of ticks in the Yangtze River Delta urban agglomeration mainly included the mean temperature of the wettest quarter and the precipitation of the coldest quarter, with 26.1% and 23.6% contributions to tick distributions. The high-, medium- and low-suitable habitats of ticks were 20 337.08, 40 017.38 km2 and 74 931.43 km2 in the Yangtze River Delta urban agglomeration in 2020, respectively. The climate changes led to south expansion of the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2070, and the total areas of suitable habitats of ticks was predicted to increase by 18 100 km2. In addition, the high-, medium- and low-suitable habitats of ticks were predicted to increase to 24 317.84, 45 283.02 km2 and 83 766.38 km2 in the Yangtze River Delta urban agglomeration in 2070, respectively. Conclusions Multiple tick species are widespread in the Yangtze River Delta urban agglomeration, and the future climate changes may lead to expansion of tick distribution in these areas.
