ABSTRACT

ObjectiveTo determine the therapeutic effect of Gegentang granules on a disease-syndrome mouse model combining human coronavirus 229E (hCoV-229E) pneumonia with Hanshi Yidu Xifei syndrome in vivo. MethodMice were randomly divided into normal group, infection group, cold-dampness group, model group, chloroquine phosphate group (0.18 g·kg-1), interferon-α2b (IFN-α2b) group (1.83×106 U·kg-1), Gegentang granules high-dose and low-dose groups (6.6, 3.3 g·kg-1) with 10 mice in each group. Cold-dampness environment and hCoV-229E infection were used for modeling, and the general status and lung index of mice in each group were observed. The viral load in lung tissue was detected by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR), the pathological changes in lung tissue were evaluated by hematoxylin-eosin (HE) staining, the levels of serum gastrointestinal hormones and inflammatory factors in lung tissue were detected by enzyme-linked immunosorbent assay (ELISA), and the percentage of peripheral blood lymphocytes was detected by flow cytometry. ResultComparing with model group, Gegentang granules could significantly alleviate the physical signs of Hanshi Yidu Xifei syndrome, including listlessness, weakness of limbs, sticky stool, etc. Comparing with model group, Gegentang granules high-dose group significantly reduced lung index, histopathological score of interstitial lung and bronchus, and the level of serum motilin (P<0.05, P<0.01), two doses of Gegentang granules could significantly increase the level of serum gastrin (P<0.05, P<0.01), the percentage of CD4+, CD8+ T lymphocytes in peripheral blood (P<0.05, P<0.01), and the level of tumor necrosis factor-α (TNF-α) in lung tissue was significantly decreased (P<0.01), and the level of interleukin-6 (IL-6) showed decreasing tendency. ConclusionGegentang granules has therapeutic effect on model mice. It can improve the appearance and behavior characterization, regulate the level of gastrointestinal hormones, decrease lung index and histopathological score, and possibly play an immunomodulatory role by inhibiting the expression of inflammatory cytokines in lung tissue and restoring the percentage of peripheral blood lymphocytes.

ABSTRACT

OBJECTIVES@#To study the effect of intrapartum antibiotic prophylaxis (IAP) of group B streptococcus (GBS) infection on the incidence and bacteriological profile of early-onset neonatal sepsis (EONS).@*METHODS@#A retrospective analysis was performed on the medical data of 494 pregnant women with positive GBS screening results and 526 neonates born by these women. According to whether the pregnant woman received IAP, the neonates were divided into two groups: IAP (n=304) and control (n=222). The two groups were compared in terms of clinical indices, incidence rate of EONS, and distribution of pathogenic bacteria in blood culture.@*RESULTS@#Compared with the control group, the IAP group had a significantly lower proportion of children with abnormal clinical manifestations (P<0.001) and a significantly lower incidence rate of EONS (P=0.022). In the IAP group, Escherichia coli (2.3%) was the most common type of pathogenic bacteria in blood culture of the neonates with EONS, while GBS (3.2%) was the most common type of pathogenic bacteria in the control group. The IAP group had a significantly higher detection rate of ampicillin-resistant Escherichia coli than the control group (P=0.029).@*CONCLUSIONS@#Although IAP can significantly reduce the incidence rate of EONS in neonates born to pregnant women with positive GBS screening results, the infection rate of ampicillin-resistant Escherichia coli may increase after IAP treatment. Therefore, it is needed to enhance the monitoring of blood culture results of neonates with EONS and timely adjust treatment plan according to drug susceptibility test results.

ABSTRACT

Objective By making biomechanical analysis of double poling (DP) technique on uphill terrain used by Chinese male cross-country (XC) skiers, to characterize biomechanical differences in DP for skiers at different levels, and determine the influence from motion techniques of skiers on their sports performance. Methods Twenty-four male XC skiers who participated in the 15 km classical race at the Beishan ski resort in Jilin, China, on Sept. 11-12, 2019 were selected in this study. On the basis of their race performance, they were divided into faster skiing group (n=12) and slower skiing group (n=12). The kinematic variables of the skiers were obtained by three-dimensional (3D) shooting, and the differences in cycle characteristics, action phases and key technique variables for skiers in two groups were analyzed. Results Faster skiers had a faster DP velocity. There was a positive correlation between swing distance and velocity. The swing distance was positively correlated with average angular velocity of elbow extension in poling phase, average angular velocity of shoulder extension in swing phase, and range of motion (ROM) of shoulder abduction. The swing distance was negatively correlated with extension of the elbow in poling phase. All the above variables showed statistical differences between faster and slower skiers. Conclusions For a long distance competition, the difference in DP velocity on uphill terrain was mainly casued by the difference in swing distance, which originated from the swing phase. Faster skier had a longer swing distance. The differences in the swing distance came mainly from the shoulder and elbow joints. Therefore, slower XC skiers in China should strengthen muscle strength of the upper limbs, especially the shoulder and elbow joint strength. More forward body leaning and larger hip and knee flexion angle at pole plant might help the skier to cover more distance.

ABSTRACT

Objective:To investigate the clinical features of direct and indirect carotid cavernous fistulas (CCFs).Methods:Patients with CCF treated in the Affiliated Hospital of Xuzhou Medical University from January 2010 to August 2020 were enrolled retrospectively. Relevant clinical data were collected, including the main clinical manifestations, neuroimaging features, and treatment methods. The clinical features of direct and indirect CCFs were compared.Results:A total of 31 patients were enrolled in the study, 29 (93.5%) had ocular symptoms, of which conjunctival hyperemia and edema ( n=24, 77.4%), exophthalmos ( n=19, 61.3%) and orbital murmur ( n=18, 58.1%) were most common. There were 23 patients (74.2%) in direct CCF group and 8 (25.8%) in indirect CCF group. The former had more history of head trauma (78.2% vs. 12.5%; P=0.002), more flow volume (high-flow CCFs: 100% vs. 37.5%; P<0.001) and more likely to cause orbital murmur (69.6% vs. 25.0%; P=0.043). Endovascular embolization was safe and effective. The common methods of endovascular embolization were EVAL glue combined with coil embolization ( n=18, 66.7%) and detachable balloon embolization alone ( n=6, 22.2%). Conclusion:Ocular manifestations are most prominent in patients with CCFs. Direct CCF is more common, usually with a history of head trauma, and the clinical and imaging features are more typical. Interventional embolization is the preferred treatment option for patients with CCF.

ABSTRACT

The surveys of the number of TCM ancient books, the bibliography classification methods, the bibliography publication, the bibliography network sharing and access, the evaluation of the classification method of subject bibliography on TCM ancient books and the relevant opinions and suggestions were sent to 30 TCM libraries and 24 comprehensive libraries in China. The questionnaires’ data and responses were analyzed, in order to understand the classification methods of TCM ancient books, the use situation, and the needs in the classification and cataloging work. The results showed that compared with the comprehensive libraries, the collection of TCM ancient books were concentrated in TCM libraries, the classification methods for TCM libraries were seldomly reported, and the classification methods were mainly self-compiled. Thus, the uniformity of the classification methods was poor, and there was also a significant gap in the standardization of the bibliography arrangement in TCM libraries. The result recommended that the domestic library industry urgently needed a unified and standardized classification for TCM ancient books. It was significant for promoting the sharing and exchange of TCM ancient books, promoting the standardization process of TCM information, and promoting the efficient implementation of Zhonghua Yizang compilation project.

ABSTRACT

According to the classification of traditional Chinese medicine syndromes of coronavirus disease 2019 by the national competent authority, this study determined that human coronavirus 229 E(HCoV-229 E) was infected in a mouse model of cold and dampness syndrome, so as to build the human coronavirus pneumonia with pestilence attacking lung syndrome model. The model can simulate the traditional Chinese medicine treatment of common disease syndromes in Coronavirus Disease 2019 Diagnosis and Treatment Program(the sixth edition for trial). Specific steps were as follows. ABALB/c mouse model of cold and dampness syndrome was established, based on which, HCoV-229 E virus was infected; then the experiment was divided into normal control group, infection control group, cold-dampness control group, cold-dampness infection group(the model group), high-dose Chaiyin Particles group(8.8 g·kg~(-1)·d~(-1)), and low-dose Chaiyin Particles group(4.4 g·kg~(-1)·d~(-1)). On the day of infection, Chaiyin Particles was given for three consecutive days. Lung tissues were collected the day after the last dose, and the lung index and inhibition rate were calculated. The nucleic acid of lung tissue was extracted, and the HCoV-229 E virus load was detected by Real-time fluorescent quantitative RT-PCR. Blood leukocytes were separated, and the percentage of T and B lymphocytes was detected by flow cytometry. Lung tissue protein was extracted, and IL-6, IL-10, TNF-α and IFN-γ contents were detected by ELISA. High and low-dose Chaiyin Particles significantly reduced the lung index(P<0.01) of mice of human coronavirus pneumonia with pestilence attacking the lung syndrome, and the inhibition rates were 61.02% and 55.45%, respectively. Compared with the model control group, high and low-dose Chaiyin Particles significantly increased cross blood CD4~+ T lymphocytes, CD8~+T lymphocytes and total B lymphocyte percentage(P<0.05, P<0.01), and reduced IL-10, TNF-α and IFN-γ levels in lungs(P<0.01). In vitro results showed that TC_(50), TC_0, IC_(50) and TI of Chaiyin Particles were 4.46 mg·mL~(-1), 3.13 mg·mL~(-1), 1.12 mg·mL~(-1) and 4. The control group of in vitro culture cells had no HCoV-229 E virus nucleic acid expression. The expression of HCoV-229 E virus nucleic acid in the virus control group was 1.48×10~7 copies/mL, and Chaiyin Particles significantly reduced HCoV-229 E expression at doses of 3.13 and 1.56 mg·mL~(-1), and the expression of HCoV-229 E nucleic acid was 9.47×10~5 and 9.47×10~6 copies/mL, respectively. Chaiyin Particles has a better effect on the mouse model with human coronavirus pneumonia with pestilence attacking the lung syndrome, and could play a role by enhancing immunity, and reducing inflammatory factor expression.

ABSTRACT

"TCM syndrome of plague attack lung" is a classification of traditional Chinese medicine syndromes of the novel coronavirus pneumonia by the Beijing Municipal Administration of Traditional Chinese Medicine. In this study, a mouse model combining disease with syndrome of human coronavirus pneumonia with cold-dampness pestilence attacking the lung was established for the first time, and the therapeutic effect of matrine sodium chloride injection was evaluated based on immune regulation and inflammatory damage. Lung index, lung index inhibition rate and HE stain were used to evaluate the therapeutic effect of matrine sodium chloride injection on the model mice; the viral load in lung tissue was measured by RT-PCR to evaluate its antiviral effect; the percentage of CD4+ T cells, CD8+ T cells and B cells were detected by flow cytometry to evaluate its immunomodulatory effect; the production of interleukin 6 (IL-6), IL-10, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured by ELISA to evaluate its anti-inflammatory effect. All interventions and operations in the experiment were approved by the Animal Ethics Committee of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences, and conformed to the Guide for the Care and Use of Laboratory Animals published by the US National Institutes of Health (NIH) and Beijing Experimental Animal Ethics Committee. The results showed that intraperitoneal injection of the high-dose (36.67 mL·kg-1·d-1) and low-dose (18.33 mL·kg-1·d-1) of matrine sodium chloride injection significantly improved the pathological damage of lung tissue and reduced lung index. The lung index inhibition rates were 86.86% and 76.53%, respectively. The production of IL-6, IL-10, TNF-α, IFN-γ, as well as the viral load in lung tissue were reduced significantly compared to the model; the percentage of CD4+ T cells, CD8+ T cells and B cells in peripheral blood were increased compared to the model. These results indicated that the matrine sodium chloride injection has an evident therapeutic effect on the model, and its mechanism was related to the inhibition virus replication, regulation of immunity function and inhibition of inflammatory factor release. This study provided laboratory data support for matrine sodium chloride injection which was used to treat the novel coronavirus pneumonia in clinical in Hubei province. These results indicated that the matrine sodium chloride injection has a good prospect for prevention and treatment of the novel coronavirus pneumonia.

ABSTRACT

Hand-foot-mouth disease (HFMD) is a common infectious disease caused by enterovirus in children. It has a high incidence and can cause fatal complications such as pulmonary edema, myocarditis and aseptic meningitis, seriously threatening the health of children. At present, some core problems such as the pathogenesis of disease, the relationship between different genotypes of pathogenic viruses, the pharmacodynamic evaluation methods, and the antiviral mechanism of drugs are still unclear. The construction of disease animal models with simulation performance of human exposure is the key to solve the above problems. Researchers both at home and abroad have established a variety of animal models for HFMD, of which enterovirus 71 (EV71) and coxsackievirus A16 (CA16) are most common and most widely used. Both EV71 and CA16 are enterovirus A in picornavirus family, so they have similarities in terms of pathogenicity, infection and replication characteristics, clinical symptoms caused by infection and immune response, but also have significant differences in age of susceptibility, method of infection, as well as neurotoxicity, clinical symptoms and signs, and degree of tissue and organ damage. Therefore, researchers shall select and establish proper animal models based on actual conditions, which is critical to the reliability of the results. In this paper, the different types of HFMD animal models established by EV71 and CA16 viruses were reviewed, especially on the species strains, virus strain types, infection methods, and characteristics of viral infections in each model, and the characteristics and clinical symptoms of HFMD induced by EV71 and CA16 were also investigated to provide reference for related research.

ABSTRACT

Bronchopulmonary dysplasia (BPD) is one of the most common chronic lung diseases in neonates especially in preterm infants. It is also the main reason leading to a poor prognosis. The prognosis of the neonates with BPD is unsatisfactory with current treatment strategies. Recent clinical trails have found that mesenchymal stem cell (MSC) transplantation might be effective and promising for treatment of BPD in neonates. This article outlines the characteristics of MSC and the potential mechanisms of MSC transplantation for BPD in vivo, and the safety and feasibility of MSC transplantation in BPD neonates, as well as the challenges in clinical trials on MSC transplantation for treatment of BPD.

ABSTRACT

Objective To explore the CT and pathologic manifestations of the pulmonary chondroma,to improve the diagnostic accuracy and reduce the misdiagnosis.Methods The CT data of 6 patients with pulmonary chondroma proved by pathology were analyzed retrospectively.Results All 6 cases were solitary,3 cases occurred in the right lung and the other 3 cases occurred in the left lung.The diameter of the lesions ranged from 1.0 cm to 5.1 cm.2 cases showed lobulated shape,4 cases showed round shape.4 cases showed circumscribed margin,2 cases showed blurrmed margin.Furthermore,calcification was detected in 1 case.Conclusion Pulmonary chondroma has some characteristic CT features,including vascular border sign and begonia sign.However,it should be differentiated from pulmonary hamartoma,peripheral lung cancer and sclerosing pneumocytoma.

ABSTRACT

Objective@#To compare the effect of combined therapy using lamivudine (LAM) plus adefovir (ADV) versus telbivudine (LdT) plus adefovir corresponding to the renal function of CHB patients.@*Methods@#A total of 120 patients with chronic hepatitis B were enrolled. According to single daily dosing, they were divided into 4 groups: LdT + ADV group (n = 32), ADV+LdT group (n = 28), LAM + ADV group (n = 38) and ADV + LAM group (n = 22). Hepatorenal function, HBV serological markers, HBV DNA quantification, creatine kinase (CK) and other parameters were examined every 3 months. Serum alanine aminotransferase (ALT) normalization rate, undetectable HBV DNA rate, hepatitis B e antigen (HBeAg) seroconversion rate, level of serum creatinine (CR) and estimated glomerular filtration rate (eGFR) were analyzed at baseline time, and at weeks 24 and 52.Stastical data were analyzed by t- test and analysis of variance, count data using χ 2 test.@*Results@#There was no statistically significant difference between the four groups in terms of ALT normalization rate, HBeAg seroconversion rate, undetectable HBV DNA rate at 24 and 52 weeks. Compared with baseline, at 24 weeks of treatment, there was no significant change in serum creatinine and eGFR in the 4 groups, but after 52 weeks of treatment, serum creatinine decreased in LdT + ADV and ADV + LdT groups and eGFR increased (P < 0.05); Serum creatinine in ADV and ADV + LAM increased, and eGFR was decreased than before (P < 0.05). After treatment, there was no significant difference in renal function between the four groups at 24 weeks, but at week 52, eGFR increased and serum creatinine decreased in LdT + ADV group compared with LAM + ADV group (P < 0.05); ADV + LdT Compared with ADV + LAM group, eGFR increased and serum creatinine decreased (P < 0.05). At 52 weeks of treatment, 5 patients with mildly impaired renal function in the ADV + LdT group [n = 10, eGFR 60-90 ml·min-1 ·(1.73 m2)-1] returned to normal, and none of the ADV + LAM group (n = 9) returned to normal.@*Conclusion@#For patients with mild impaired renal function, adding LdT combined with ADV can improve renal function compared to that of LAM plus ADV.
