Objective In order to understand the current resistance status of Aedes albopictus(Ae. albopictus) adult population to commonly used insecticides and the resistance dynamics development in Zhejiang Province and provide a theoretical basis for the scientific and rational use of hygienic insecticides. Methods Resistance determination was carried out using the diagnostic dose method(GB/T 26347-2010)recommended by WHO in the adult mosquito contact cylinder method to monitor the resistance of Ae. albopictus field populations in 11 cities and districts in Zhejiang Province in 2024. Results The monitoring result showed that adult Ae. albopictus in 11 areas were resistant or suspected resistant populations to both cis-cypermethrin and permethrin; suspected and resistant populations to the organophosphate insecticide malathion were as high as 81.82%; while suspected resistance to the carbamate insecticide residual carbofuran accounted for 45.45%, and the rest of the monitoring sites were sensitive to it. Conclusions The result suggest that the generalized resistance of Ae. albopictus populations to pyrethroids and organophosphorus insecticides in the field in Zhejiang Province needs to be highly emphasized. In future mosquito vector and mosquito-borne disease control, insecticides should be selected based on the resistance monitoring information, while following scientific guidelines for insecticide use.

Following the release of the Technical Requirements on Quality Control and Standard Establishment of Traditional Chinese Medicine Formula Granules by the National Medical Products Administration in 2021, Chinese Pharmacopoeia Commission has promulgated 296 national drug standards so far, and most provinces have started the work of establishing provincial standards as supplements. The promulgation of standards fostered high-quality development of the industry. Since the implementation of national and provincial standards for more than three years, enterprises have gained deep understanding and hands-on experiences on the characteristics, technical requirements, production process, and quality control of traditional Chinese medicine(TCM) formula granules. Meanwhile, challenges have emerged restricting the high-quality development of this industry, including how to formulate quality control strategies for medicinal materials and decoction pieces, how to reduce manufacturing costs, and how to improve the pass rate and product stability under high standards. Based on the work experiences from standard management and process research, this article analyzed the distribution of sources, processing methods, dry extract rate ranges, process requirements for volatile oil-containing decoction pieces, control measures of safety indices, characteristics and trends of setting characteristic chromatograms or fingerprints, characteristics and trends of setting content ranges, and main differences between national standards and provincial standards. On the one hand, this article aims to present main characteristics for deeply understanding different indicators in standards and provide basic ideas for establishing quality and process control systems. On the other hand, from the perspective of industrial practice, suggestions are put forward on the important aspects that need to be focused on in the quality and process control of TCM formula granules.

Objective To explore the correlation between serum insulin-like growth factor1(IGF-1),insulin-like growth factor binding protein3(IGFBP-3),bone-specific alkaline phosphatase(BAP)and abundance of intestinal flora in children with idiopathic short stature(ISS).Methods A total of 86 children with ISS who were treated with short-acting recombinant growth hormone for the first time in Department of Endocrinology of Baoding Hospital,Beijing Children's Hospital,Capital Medical University,were enrolled from July 2021 to June 2023.Before treatment and at 6 months after treatment,physical indexes(height,weight)and bone age indexes[bone age index(BAI),bone age difference(BAD)]were detected with the same instrument at the same place.The fasting venous blood was collected to detect levels of serum IGF-1,IGFBP-3 and BAP by enzyme-linked immunosorbent assay.The abundances of intestinal floras were monitored by 16s rDNA high-throughput sequencing technology combined with bioinformation analysis technology.A total of 40 healthy children during the same period were enrolled as control group,and differences in different indexes within the same groups or between the two groups were compared by independent sample t test or paired t test.The correlation between abundances of intestinal floras and levels of serum IGF-1,IGFBP-3 and BAP was analyzed by Pearson correlation analysis.Results Compared with the control group.the height,weight,BAD,BAI,levels of serum IGF,IGFBP-3 and BAP,Chaol,Shannon and Pielou e of ISS patients decreased before treatment,and the differences were statistically significant(t=7.119～44.143,all P<0.05).After treatment,height,weight,BAD,BAI,levels of serum IGF,IGFBP-3 and BAP,Chaol,Shannon and Pielou e were increased in ISS children(t=3.145～39.188),the above indexes were still lower than those in control group(t=2.389～69.893),the differences were statistically significant(all P<0.05),respectively.In intestinal floras,dominant bacterial groups at phylum level were Firmicutes,Bacteroidetes,Actinobacteria and Proteobacteria,while dominant bacterial groups at genus level were Blautia,Bifidobacterium,Faecalibacterium and Bacteroides.Compared with the control group,before treatment,the abundances of Actinobacteria and Proteobacteria increased in the ISS group,while the abundances of Bacteroidetes,Bifidobacteria and Bacteroides decreased,and the differences were statistically significant(t=25.224～46.345,all P<0.05).After treatment,abundances of Bacteroidetes,Bifidobacterium and Bacteroides in the ISS group increased compared to before treatment,while abundance of Proteobacteria decreased,and the differences were statistically significant(t=10.055～39.245,all P<0.05).The abundances of Bacteroidetes,Bifidobacterium and Bacteroides in ISS group were lower than those in control group,while abundance of Proteobacteria was higher than that in control group,and the differences were statistically significant(t=6.290～20.540,all P<0.05).The abundances of Bacteroidetes,Bifidobacterium and Bacteroides were positively correlated with levels of serum IGF-1,IGFBP-3 and BAP(r=0.300～0.759,all P<0.05).Conclusion The abundances of intestinal floras are decreased,and the structure is abnormal in children with ISS.The abundances of beneficial bacteria in intestinal floras are related to levels of serum IGF-1,IGFBP-3 and BAP.In clinical treatment of ISS,combined treatment with intestinal flora disorders may be conducted.

Objective:To compare the efficacy of robot system-assisted versus freehand screw revision for ankylosing spondylitis (AS) with lower cervical fractures.Methods:A multicenter retrospective cohort study was conducted to analyze the clinical data of 57 patients with AS combined with lower cervical fractures admitted to Honghui Hospital Affiliated to Xi'an Jiaotong University School of Medicine, Henan Provincial People's Hospital, Zhengzhou Orthopedic Hospital, and Qilu Hospital of Shandong University, including 46 males and 11 females, aged 38-77 years [(65.4±9.5)years]. Injury segments involved C 3 in 7 patients, C 4 in 13, C 5 in 25, C 6 in 10, and C 7 in 2. All the patients underwent revision surgery, among whom, 22 patients were treated with robot system-assisted cervical pedicle screw placement (robot nailing group, with 190 screws), and 35 with freehand cervical pedicle screw placement (freehand nailing group, with 300 screws). The operative duration, intraoperative bleeding volume, frequency of intraoperative fluoroscopy, incision length, and length of hospital stay of the two groups were compared; the time of single nscrew insertion, the number of single nail revisions, the distance between screws and the anterior cortex, the accuracy of screw placement of grade 0 and grade 0+1 were recorded in the two groups. The visual analogue scale (VAS), Japanese Orthopedic Society (JOA) score, neck dysfunction index (NDI), American Spine Injury Association (ASIA) classification before operation, at 3 days, 3 months after operation and at the last follow-up were compared between the two groups. The complication rate was also noted. Results:All the patients were followed up for 12-16 months [(14.3±2.1)months]. The operative duration, intraoperative bleeding volume, and frequency of intraoperative fluoroscopy were (186.4±12.9)minutes, (486.1±68.6)ml, and (3.4±1.3)times in the robot nailing group, which were shorter or less than (206.7±14.4)minutes, (660.3±45.2)ml, and (13.5±3.6)times in the freehand nailing group ( P<0.01). The incision length was (9.4±2.4)cm in the robot nailing group, longer than (5.6±1.2)cm in the freehand nailing group ( P<0.01), and the length of hospital stay was (3.7±0.4)days, shorter than (4.4±1.4)days in the freehand nailing group ( P<0.01). The length of single nail insertion, the number of single nail revision, and the distance between the screws and the front cortex were (6.5±0.4)minutes, (1.1±0.1)times, and (3.5±1.3)mm in the robot nailing group, which were shorter or less than (11.6±0.2)minutes, (1.5±0.2)times, and (12.4±4.7)mm in the freehand nailing group ( P<0.01). The accuracy of the screw placement in the robot nailing group was 90.0% (171/190) and 95.8% (182/190) with level 0 and 0+1 screws, better than 80.0% (240/300) and 89.0% (267/300) in the freehand nailing group ( P<0.05). There was no significant difference in VAS, JOA score, NDI, or ASIA grading between the two groups before operation ( P>0.05). The VAS, JOA, and NDI scores at 3 days after operation were (3.1±0.6)points, (12.1±1.2)points, and (15.6±2.9)points, respectively in the robot nailing group, which were better than (5.0±1.4)points, (11.3±1.1)points and (22.5±3.7)points, respectively in the freehand nailing group ( P<0.05). No statistically significant difference was observed in the ASIA grade between the two groups at 3 days after operation ( P>0.05). There were no significant differences in VAS, JOA, NDI scores, or ASIA grading between the two groups at 3 months after operation and at the last follow-up ( P>0.05). Compared with those before operation, the VAS, JOA, NDI scores, and ASIA grading were significantly improved at 3 days, 3 months after operation and at the last follow-up in the two groups, which were further improved with the passage of time. Two patients in the robot nailing group had pneumonia, with a complication rate of 9% (2/22), while 2 patients in the freehand nailing group had dural sac rupture and cerebrospinal fluid leakage and 3 had lung infection after operation, with a complication rate of 14% (5/35) ( P<0.05). Conclusion:Compared with freehand nailing, the robot system-assisted nailing revision for AS with lower cervical fracture has more advantages in terms of the operative duration, length of hospital stay, intraoperative bleeding volume, frequency of intraoperative fluoroscopy nailing speed and accuracy, screw holding force, early pain relief, function restoration, and complication rate, despite longer surgical incision.

For middle-aged and elderly patients with conditions such as spinal fractures and degenerative spinal diseases, spinal internal fixation is a core surgical procedure for reconstructing spinal stability, heavily relying on the biomechanical stability provided by pedicle screw systems. Whereas, these patients are often complicated by osteoporosis that can significantly compromise the stability of the bone-pedicle screw interface, leading to a marked increase in pedicle screw loosening and surgical failure rates. The bone cement-augmented pedicle screw technique, which involves injecting bone cement into the vertebral body or screw trajectory to optimize the mechanical properties of the bone-pedicle screw composite, has been proven to significantly enhance fixation strength and effectively prevent screw-related failures, thereby reducing the incidence of internal fixation failure in high-risk populations undergoing spinal fusion. However, the widespread clinical application of this technique has faced challenges such as inaccurate clinical decision-making (indication and contraindication selection), non-standardized operative practices, and insufficient awareness of complication prevention, resulting in considerable variability in clinical outcomes and even severe complications. To address this, Prof. Luo Fei from First Affiliated Hospital of Army Medical University initiated the project and the Chinese Association Orthopaedic Surgeons organized relevant experts to develop the Evidence-based clinical practice guideline for bone cement-augmented pedicle screw technique ( version 2025), based on current evidence. The guidelines put forward 8 recommendations regarding the clinical value, scope of application, and operational standards of the technique, aiming to provide evidence-based medical support and technical standardization for clinical decision-making.

Aim To explore the mechanism of Con-grong Shujing granule(CSGs)in the treatment of Par-kinson's disease(PD)by network pharmacology,mo-lecular docking and parallel reaction monitoring(PRM)technology.Methods The active components of CSGs and the target genes of Parkinson's disease were obtained through the database.The intersection targets of drugs and diseases were selected to construct the"drug-active ingredient-target"and protein interac-tion network.The intersection target genes were impor-ted into David database for GO and KEGG enrichment analysis,and the main components were docked with key targets.27 SD rats were randomly divided into the normal group(n=9),model group(n=9)and treat-ment group(n=9).On day 1,7 and 14 of treatment,PRM analysis was used to detect the changes in the specific peptides of key target proteins in the substantia nigra of rats.Results The main components of CSGs wereTanshialdehyde,Baicalein,Quercetin and Kaempferol.The most important targets for the treat-ment of PD were TP53,AKT1,EGFR,HSP90 AA1 and STAT3.KEGG analysis mainly enriched MAPK,PI3K-Akt and neurotrophic factor signaling pathway.The molecular docking between core components and core targets showed that the binding of drugs and targets had good activity.PRM analysis of key proteins found that the target peptide expression levels of ASK1,JNK1 and JNK3 were different among groups(P＜0.05).Con-clusion CSGs can alleviate ERS,inhibit apoptosis and play a neural protective role through the ASK1-JNK pathway.

Isoflavones which mainly distributed in leguminous plants have plenty of health benefits.Isoflavone synthase(IFS)is a membrane-associated cytochrome P450 enzyme(CYP450)which carries out the unique aryl-ring migration and hydroxylation.So far,few crystal structures of plant P450s have been obtained.We determined the crystal structure of IFS from Medicago truncatula at 1.9 ? by MAD method using a selenomethionine substituted crystal and conducted molecular docking and mutagenesis study.The structure of IFS complexed with imidazole exhibits the helix Ⅰa-loop-helix Ⅰβ motif which cor-responds to helix Ⅰ of other P450s.Compared with structures of common P450s,IFS/imidazole structure contains an extra domain,i.e.,the γ-domain.The structure reveals a homodimer in which the γ-domain of one molecule interacts with the β-domain of another.The plane of heme group makes an angle of ap-proximately 40° with the helix Ⅰa-loop-helix Ⅰβ motif.Molecular docking combined with mutagenesis study suggested that Trp-128 and Asp-300 might play important roles in substrate binding and recogni-tion.Phe-301,Ser-303 and Gly-305 from the helix Ⅰa-loop-helix Ⅰβ motif may play important roles in the aryl-ring migration.These novel structural features reveal insights into the unique reaction mechanism of IFS and provide a basis for engineering IFS in leguminous crops for health purpose.

Objective:To explore the effect of multiple modified process management intervention on cardiac func-tion,psychological state,stress level,sleep quality and adverse events in patients with severe coronary atherosclerot-ic heart disease(CHD).Methods:This randomized controlled study enrolled 130 severe CHD patients who were treated in Affiliated Beijing Shijitan Hospital of Capital Medical University between January 2020 and May 2023.Patients were randomly divided into control group(n=65)and intervention group(n=65).Patients in the control group were treated with routine management intervention,while those in the intervention group were given addi-tional multiple modified process management interventions.Both groups were intervened for 4 weeks.Cardiac func-tion,levels of norepinephrine(NE)and cortisol(COR),scores of Self-rating Anxiety Scale(SAS),Self-rating Depression Scale(SDS),General Comfort Questionnaire(GCQ),Pittsburgh Sleep Quality Index(PSQI),and the incidence of adverse events during intervention were compared between the two groups.Results:Compared to those in control group after intervention,patients in intervention group had significant higher left ventricular ejection fraction(LVEF)[(57.81±2.15)％vs.(50.11±2.99)％]and GCQ score[(95.88±5.37)points vs.(75.81±6.67)points](P＜0.001 all),and significant lower left ventricular end-diastolic volume(LVEDV)[(109.81±5.37)ml vs.(129.26±5.17)ml],left ventricular end-systolic volume(LVESV)[(50.85±3.08)ml vs.(66.02±3.77)ml],levels of NE[(61.56±5.49)pg/ml vs.(69.86±5.03)pg/ml],COR[(85.63±5.19)ng/ml vs.(92.28±6.57)ng/ml],scores of SAS[(30.06±5.19)points vs.(49.51±5.85)points],SDS[(31.86±4.51)points vs.(40.00±5.10)points]and PSQI[(8.72±1.58)points vs.(13.89±2.40)points],and incidence of ad-verse events(4.69％vs.23.44％)(P＜0.01 all).Conclusion:The multiple modified process management interven-tion may improve the cardiac function,adverse psychological state,stress level,sleep quality and reduce the inci-dence of adverse events in patients with severe CHD.

Clinical pharmacist training is an important way to strengthen the clinical pharmacist team's construction and improve their pharmaceutical service capabilities and levels.The Pharmacy Administration and Pharmacy Practice in Healthcare Institutions-Part 4-8-1:Pharmacy Administration-Pharmacy Training Management-Clinical Pharmacist Training was based on the relevant requirements of the current clinical pharmacist training system of the Chinese Hospital Association,and formulated by sor-ting out relevant materials,such as standards,policies and regulations,technical specifications,literature,the current situation of clinical pharmacist training in China,and expert opinions.A total of 15 key elements of clinical pharmacist training were selected and divided into three aspects(base management,training process and assessment,and the quality management,evaluation and improvement).This article mainly introduced the construction method and content of the clinical pharmacist training standard,to deepen the understanding of the standard for relevant units and to promote the implementation of the standard.
