This study aims to evaluate the effectiveness and economic efficiency of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in the treatment of chronic rhinosinusitis(CRS). The randomized controlled trial(RCT) of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in the treatment of CRS was searched against EMbase, PubMed, Cochrane Library, CNKI, VIP, SinoMed, and Wanfang. The efficacy, nasal mucociliary transport time, and safety of the therapy above in the treatment of CRS were analyzed with single-group rate and Meta-analysis, and the economy and sensitivity were evaluated from the perspective of payer. A total of 9 RCTs were included, including 1 145 patients. Meta-analysis showed that compared with Triamcinolone Acetonide Nasal Spray alone, Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in the treatment of CRS patients increased the effective rate(RR=1.17, 95%CI[1.11, 1.24], P<0.000 01) and shortened the nasal mucociliary transport time(MD=-3.32, 95%CI[-5.86,-0.78], P=0.01), there was no significant difference in the incidence of adverse reactions between the two groups. The incremental cost-effectiveness analysis showed that the treatment costs of the control group and the observation group were 44.15 yuan and 1 044.96 yuan, respectively. In the Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray treatment group, 75.48 yuan was spent to improve the effective rate of CRS by 1%. The one-way sensitivity analysis indicated the days of treatment, the RR of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray, the price of unit preparation of Biyuan Tongqiao Granules, and the effective rate of Triamcinolone Acetonide Nasal Spray alone had great influence on the incremental cost-effectiveness ratio. In conclusion, Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray improves the therapeutic effect on CRS. The probabilistic sensitivity analysis showed that when the willingness to pay was greater than 7 920 yuan(less than 0.1 of GDP per capita 8 098 yuan), the combined therapy was economically superior to the control. Due to the limited number of articles published, it is necessary to carry out a real-world clinical trial of Biyuan Tongqiao Gra-nules and Triamcinolone Acetonide Nasal Spray in the treatment of CRS, so as to compare the cost-effectiveness of Biyuan Tongqiao Granules and Triamcinolone Acetonide Nasal Spray.

This study aimed to investigate the effects of geniposide(GP) on the expression of prokineticin(PK2) and prokineticin receptor 1(PKR1) in db/db mice with diabetic nephropathy(DN), so as to explore how the PK2 signaling pathway participated in the pathological changes of DN and whether GP exerted the therapeutic effect through this signaling pathway. Male mice were randomly divided into four groups, namely db/m, db/db, db/db+GP, and db/m+GP groups, with five in each group. The mice in the db/db+GP and db/m+GP groups were gavaged with 150 mg·kg~(-1) GP for eight successive weeks. Afterwards, all the mice were sacrificed and the renal tissues were embedded. The morphological changes in glomerulus and renal tubules were observed by Masson and PAS staining. The expression levels of PK2, PKR1, and Wilm's Tumor Protein 1(WT_1) in podocytes were detected by immunohistochemistry, and the protein expression levels of PK2 and PKR1 in mouse kidney by Western blot. The morphological results showed serious glomerular and tubular fibrosis(Masson), high glomerular and tubular injury score(PAS), increased glomerular mesangial matrix, thickened basement membrane, exfoliated brush border of renal tubules, decreased WT_1 in glomerular podocytes, and massive loss of podocytes in the db/db group. After administration with GP, the glomerular and tubular fibrosis was alleviated, accompanied by improved glomerular basement membrane and renal tubule brush edge, and up-regulated WT_1. As revealed by further protein detection, in the db/db group, the expression levels of PK2 and PKR1 and p-Akt/Akt ratio declined, whereas the ratio of Bax/Bcl-2 rose. Ho-wever, PKR2 and p-ERK/ERK ratio did not change significantly. After administration with GP, the PK2 and PKR1 expression was elevated, and p-Akt/Akt ratio was increased. There was no obvious change in PKR2, Bax/Bcl-2 ratio, or p-ERK/ERK ratio. All these have demonstrated that GP improves the renal damage in DN mice, and PK2/PKR1 signaling pathway may be involved in such protection, which has provided reference for clinical treatment of DN with GP.

SARS-CoV-2 infection causes complicated clinical manifestations with variable multi-organ injuries, however, the underlying mechanism, in particular immune responses in different organs, remains elusive. In this study, comprehensive transcriptomic alterations of 14 tissues from rhesus macaque infected with SARS-CoV-2 were analyzed. Compared to normal controls, SARS-CoV-2 infection resulted in dysregulation of genes involving diverse functions in various examined tissues/organs, with drastic transcriptomic changes in cerebral cortex and right ventricle. Intriguingly, cerebral cortex exhibited a hyperinflammatory state evidenced by significant upregulation of inflammation response-related genes. Meanwhile, expressions of coagulation, angiogenesis and fibrosis factors were also up-regulated in cerebral cortex. Based on our findings, neuropilin 1 (NRP1), a receptor of SARS-CoV-2, was significantly elevated in cerebral cortex post infection, accompanied by active immune response releasing inflammatory factors and signal transmission among tissues, which enhanced infection of the central nervous system (CNS) in a positive feedback way, leading to viral encephalitis. Overall, our study depicts a multi-tissue/organ transcriptomic landscapes of rhesus macaque with early infection of SARS-CoV-2, and provides important insights into the mechanistic basis for COVID-19-associated clinical complications.

The leaf spot of Belamcanda chinensis often appears in May to June and spreads rapidly during the flowering stage(July to September) in the cultivation fields, seriously affecting the yield and quality of B. chinensis. To identify and characterize the pathogens of the leaf spot, we isolated two species of Alternaria, identified them according to Koch's postulates, and tested their pathogenicity and biological characteristics. Furthermore, we determined the inhibitory effects of 6 chemical fungicides, 1 plant fungicide, and 3 microbial fungicides on the pathogens by using mycelial growth rate and plate confrontation method to select the appropriate control agents. The results showed that the two pathogens causing B. chinensis leaf spot were Alternaria tenuissima and A. alternata. The conidia of A. tenuissima often formed long chains with no or a few branches, while those of A. alternata often formed short branched chains. The optimum growth temperature of both A. tenuissima and A. alternata was 25 ℃. The two pathogens grew well in alkaline environment. The indoor fungicide screening experiments showed that 40% flusilazole had good inhibitory effects on the two pathogens, with the EC_(50) values of 12.42 mg·L~(-1) and 12.78 mg·L~(-1) for A. tenuissima and A. alternata, respectively. The results of this study provide a theoretical basis for the subsequent theoretical research and field control of B. chinensis leaf spot.

In summer in 2020, Pinellia ternata in many planting areas in Hubei suffered from serious southern blight, as manifested by the yellowing and wilted leaves and rotten tubers. This study aims to identify the pathogen, clarify the biological characteristics of the pathogen, and screen fungicides. To be specific, the pathogen was isolated, purified, and identified, and the pathogenicity was detected according to the Koch's postulates. Moreover, the biological characteristics of the pathogen were analyzed. Furthermore, PDA plates and seedlings were used to determine the most effective fungicides. The results showed that the mycelia of the pathogen were white and villous with silk luster, which produced a large number of white to black brown sclerotia. The pathogen was identified as Athelia rolfsii by morphological observation and molecular identification based on LSU and TEF gene sequences. The optimum growth conditions for A. rolfsii were 30 ℃ and pH 5-8, and the optimum conditions for the germination of sclerotia were 25 ℃ and pH 7-9. Bacillus subtilis, difenoconazole, and flusilazole were identified as effective fungicides with PDA, and their half maximal effective concentration(EC_(50)) was all less than 5 mg·L~(-1). The effective fungicides screened with the seedlings were hymexazol and difenoconazole. Based on the screening experiments, difenoconazole can be used as the main agent for the prevention and treatment of southern blight.

In order to identify the species and biological characteristics of the pathogen of southern blight from three kinds of Chinese medicine of Iridaceae(Belamcanda chinensis, Iris tectorum and I. japonica) in Dabie Mountains, the isolation, identification, pathogenicity and biological characteristics of the pathogens were studied according to Koch's postulates. In addition, 9 chemical fungicides, 3 botanical fungicides and 5 microbial fungicides were used to evaluate their inhibition to the isolates in vitro. The results showed that all the strains(SG-Q, YW-Q, and HDH-Q) isolated and purified from the diseased plants of B. chinensis, I. tectorum and I. japonica, respectively, were identified as Sclerotium rolfsii through morphological observation and sequence aligement of 18 S rDNA, rDNA-ITS and TEF. Field observations showed that the intensity of the disease incidence of three Iridaceae plants was B. chinensis>I. japonica> I. tectorum, and the pathogenicity of the strains was SG-Q>YW-Q>HDH-Q. For biological characteristics, SG-Q strain was suitable for growth under the 12 h light/12 h dark cycle, with the optimal growth temperature of 30 ℃ and pH of 5. Among the 9 tested chemical fungicides, 29% lime sulphure and 10% flusilazole had stronger inhibitory effect on mycelia growth of SG-Q. For 3 botanical fungicides, 1% osthol, 20% eugenol and 0.5% berberine could effectively inhibt the mycelial growth of SG-Q and cause the morphological variation of the pathogen. For 5 microbial fungicides, Trichoderma harzianum and Bacillus subtilis had better inhibition on the mycelium growth of SG-Q.

OBJECTIVE: To explore the therapeutic effect and the mechanism of the adjuvant treatment with moxibustion on coronavirus disease 2019 (COVID-19). METHODS: A total of 95 patients with COVID-19 were randomly divided into a moxibustion group (45 cases) and a basic treatment group (50 cases). The routine treatment of western medicine was applied in the patients of both groups. In the moxibustion group, on the base of the treatment of western medicine, moxibustion was applied to Dazhui (GV 14), Feishu (BL 13), Qihai (CV 6) and Zusanli (ST 36), once daily and consecutively for 14 days. At the end of treatment courses, clinical symptom scores for cough, asthmatic breathing, chest oppression and short breath, as well as their remission rates were compared between the two groups before and after treatment. Before and after treatment, the white blood cell (WBC) count, the levels of c-reactive protein (CRP) and interleukin-6 (IL-6) and the absolute number of T lymphocyte subsets, i.e. , and of the peripheral blood were compared in the patients between the two groups. The principal component analysis was adopted to analyze the common data extracted from the above 10 clinical indexes variables and comprehensively evaluate the differences in the therapeutic effect of two regimens. RESULTS: The clinical symptom scores were all decreased after treatment in both of the moxibustion group and the basic treatment group as compared with those before treatment ( CONCLUSION On the base of the routine treatment with western medicine, moxibustion therapy supplemented relieves the clinical symptoms, reduces the levels of inflammatory indexes, i.e. IL-6 and CRP as well as improves the absolute number of peripheral T lymphocyte subsets. The clinical therapeutic effect of such regimen with moxibustion supplemented is significantly better than the simple routine treatment of western medicine.
