This study conducted a pharmacoeconomic evaluation of Shaoma Zhijing Granules in the treatment of tic disorder(TD) in children. Firstly, from the perspective of the healthcare system, cost-effectiveness analysis was used to evaluate the economic efficiency of Shaoma Zhijing Granules compared with Changma Xifeng Tablets and Jiuwei Xifeng Granules in the treatment of TD in children. Then, through network Meta-analysis, the overall effectiveness of different regimens was calculated, combined with the total cost of the regimens, to calculate the incremental cost-effectiveness ratio(ICER). Finally, sensitivity analysis was performed to verify the stability of the study results and the credibility of the conclusions. This study included 17 articles, including 9 articles on Chinese patent medicines(3 on Shaoma Zhijing Granules, 2 on Jiuwei Xifeng Granules, and 4 on Changma Xifeng Tablets), for the treatment of TD in children, and 8 articles on Chinese patent medicines combined with conventional western medicines(3 on Shaoma Zhijing Granules, 2 on Jiuwei Xifeng Granules, and 3 on Changma Xifeng Tablets). In the Chinese patent medicine group, the total cost of Shaoma Zhijing Granules for treating TD was CNY 4 410.00, with clinical total effective rate of 77.53%; the total cost of Jiuwei Xifeng Granules for treating TD was CNY 5 192.70, with clinical total effective rate of 82.13%. The ICER of Jiuwei Xifeng Granules vs Shaoma Zhijing Granules was 169.95, higher than the willingness-to-pay(WTP, cost of increasing efficiency by 1% is CNY 85.70). Therefore, Jiuwei Xifeng Granules did not have a cost-effectiveness advantage over Shaoma Zhijing Granules. The total cost of Changma Xifeng Tablets for treating TD was CNY 1 282.50, with clinical total effective rate of 80.60%. The total cost of Changma Xifeng Tablets was lower and clinical total effective rate was higher than that of Shaoma Zhijing Granules. Overall, Shaoma Zhijing Granules did not have a cost-effectiveness advantage. In the Chinese patent medicine combined with conventional western medicine group, the total cost of Shaoma Zhijing Granules for treating TD + conventional western medicines was CNY 6 768.52/6 778.48, with clinical total effective rate of 96.18%. The total cost of Jiuwei Xifeng Granules + conventional western medicines for treating TD was CNY 6 522.56, with clinical total effective rate of 88.30%. The ICER of Shaoma Zhijing Granules + conventional western medicines vs Jiuwei Xifeng Granules + conventional western medicines was 31.20, lower than WTP. Therefore, Shaoma Zhijing Granules + conventional western medicines had a cost-effectiveness advantage over Jiuwei Xifeng Granules + conventional western medicines. The total cost of Changma Xifeng Tablets + conventional western medicines for treating TD was CNY 1 706.12, with clinical total effective rate of 95.39%. The ICER of Shaoma Zhijing Granules + conventional western medicines vs Changma Xifeng Tablets + conventional western medicines was 6 334.06, higher than WTP. Therefore, although Shaoma Zhijing Granules + conventional western medicines had higher clinical total effective rate compared with Changma Xifeng Tablets + conventional western medicines, it did not have a cost-effectiveness advantage. Overall, for different medication regimens(Chinese patent medicines monotherapy or in combination with conventional western medicines), Shaoma Zhijing Granules and Jiuwei Xifeng Granules both had a cost-effectiveness advantage, but compared with Changma Xifeng Tablets, neither had a cost-effectiveness advantage. For Chinese patent medicines in combination with conventional western medicines, clinical total effective rate of Shaoma Zhijing Granules in combination with conventional western medicines for the treatment of TD in children was the highest.

To investigate the influence of the strigolactone inhibitor Tis108 on the growth of Gastrodia elata, this study treated G. elata tuber with Tis108 solution of 10 μmol·L~(-1) and measured the content of endogenous hormone gibberellin(GA) in the tuber. By using reverse transcription-polymerase chain reaction(RT-PCR) technology, the key enzyme GeCYP714A1 gene involved in GA deactivation was cloned. Bioinformatics analysis on the GeCYP714A1 gene was carried out by using ExPASy, SWISS-MODEL, MEGA, etc., and its expression levels in different parts of G. elata were determined. The results showed that after Tis108 treatment, GA content in G. elata tuber was significantly increased, and the transcription level of the GeCYP714A1 gene was significantly decreased. The full length of the coding region of the GeCYP714A1 gene is 1 173 bp, encoding 390 amino acids. The protein has a molecular weight of 44.85 kDa, a theoretical isoelectric point of 9.83, an instability index of 49.20, an aliphatic index of 89.03, and a grand average of hydropathicity of-0.235, classifying it as an unstable, basic, hydrophilic protein, and the GeCYP714A1 protein was localized in the mitochondria, lacking a signal peptide and a transmembrane structure. Phylogenetic tree analysis revealed that GeCYP714A1 was most closely related to the DcCYP714C2(PKU78454.1) protein from Dendrobium candidum, with a sequence identity of 67.25%. The qRT-PCR analysis of the expression patterns of the GeCYP714A1 gene indicated that GeCYP714A1 had the highest transcription level in G. elata tuber, followed by stem and inflorescence. The study represented that Tis108 inhibited the transcription level of GeCYP714A1 involved in GA deactivation in G. elata tuber, thereby increasing the accumulation of GA and affecting the growth of G. elata tuber. These results provided a basis for further studies of strigolactone regulation of GA signal and tuber development in G. elata.

This study retrieved Croci Stigma related literature from CNKI, Wanfang, VIP, and Web of Science database, and used bibliometrics and CiteSpace 6.1.R2 software to analyze the published Croci Stigma related articles in Chinese and English from 2000 to 2022. The authors, research institutions, and keywords were visualized and analyzed, and the current status and development trend of Croci Stigma research was summarized by combining the information extraction methods. A total of 1 846 Chinese articles and 2 703 English articles were screened out and included. The results showed a generally steady increase in the number of Croci Stigma related articles. The results of the visualization analysis showed that there were more collaborations between researcher teams and major research institutions in English articles than Chinese articles. The Chinese articles was mainly published by China Pharmaceutical University, and most of the inter-institutional collaborations occurred in neighboring regions. The English articles was mainly published by Iranian institutions, and most of the cooperation occurred within the country, with less transnational cooperation. Keywords analysis showed that the research on Croci Stigma was mainly focused on chemical compositions, pharmacological effects, mechanisms, quality control, etc. It was predicted that the future research hotspots of Croci Stigma would mainly focus on pharmacological mechanism and clinical efficacy. The current research related to Croci Stigma still needs to be developed, cooperation should be strengthened, and more in-depth research should be conducted.

Objectives: To study the association of the single nucleotide polymorphisms (SNPs) of the adenylyl cyclase IX ( ADCY9 ) gene at rs1967309, rs2230739, rs2601814, rs2601825, rs2601796, and rs2283497 loci and gene-environment interaction with childhood bronchial asthma (asthma for short)., Methods: A total of 123 children with asthma who attended the hospital from March 2019 to September 2021 were enrolled as the asthma group, among whom 84 (68.3%) had mild-to-moderate attacks and 39 (31.7%) had severe attacks. A total of 124 healthy children were enrolled as the control group. The association of the SNPs and haplotypes of the ADCY9 gene at the above 6 loci with the susceptibility to childhood asthma was evaluated. The method of generalized multifactor dimensionality reduction was used to analyze gene-environment interaction., Results: Polymorphisms were observed for the ADCY9 gene at the above six loci in both the asthma and control groups, and there were significant differences in genotype and allele frequencies at the rs1967309 locus between the two groups ( P <0.05). There was no significant difference in the distribution frequency of haplotypes TA and GG between the asthma and control groups ( P >0.05). The generalized multifactor dimensionality reduction analysis showed interaction between rs1967309 locus and allergen contact ( P <0.05), which increased the risk of asthma ( OR =1.585, P <0.05)., Conclusions: The rs1967309 locus of the ADCY9 gene is associated with the susceptibility to childhood asthma, and the locus and allergen contact have a synergistic effect on the development of asthma.

Objective: To investigate the off-label use of oral glucocorticoids in outpatients., Methods: The information of outpatient glucocorticoids prescriptions from January 1st to June 30th in 2012 were collected from the information system in our hospital, then the software of Excel was employed to statistically analyze the data including the amount of drugs used in different departments,as well as the age, sex, and diagnosis of the patients. The diagnoses were compared with those included in the labels approved by China Food and Drug Administration and US Food and Drug Administration and domestic and foreign guidelines., Results: It was found that 16.53% of the cases were off-label use,and dexamethasone had the highest proportion (60.50%) of off-label use. Most of the off-label use had evidence support, such as multiple myeloma and myasthenia gravis, while some cases did not, such as epilepsy and sudden deafness., Conclusion: The management of off-label use should be further strengthened to promote the safe and rational use of glucocorticoids.

Mesoporous activated carbons containing acidic groups were prepared with cotton stalk based fiber as raw materials and H3PO4 as activating agent by one step carbonization method. Effects of impregnation ratio, carbonization temperature and heat preservation time on the yield, elemental composition, oxygen-containing acid functional groups and adsorptive capacity of activated carbon were studied. The adsorption capacity of the prepared activated carbon AC-01 for p-nitroaniline and Pb(II) was studied, and the adsorption mechanism was also suggested according to the equilibrium experimental results. The maximum yield of activated carbons prepared from cotton stalk fiber reached 35.5% when the maximum mesoporous volume and BET surface area were 1.39 cm3 x g(-1) and 1 731 m2 x g(-1), respectively. The activated carbon AC-01 prepared under a H3 PO4/precursor ratio of 3:2 and activated at 900 degrees C for 90 min had a total pore volume of 1.02 cm3 x g(-1), a micoporous ratio of 31%, and a mesoporous ratio of 65%. The pore diameter of the mesoporous activated carbon was mainly distributed in the range of 2-5 nm. The Langmuir maximum adsorption capacities of Pb(II) and p-nitroaniline on cotton stalk fiber activated carbon were 123 mg x g(-1) and 427 mg x g(-1), respectively, which were both higher than those for commercial activated carbon fiber ACF-CK. The equilibrium adsorption experimental data showed that mesopore and oxygen-containing acid functional groups played an important role in the adsorption.
