The clinical practice guidelines for Chinese patent medicines (CPM) provide reference for the selection of national drug catalogs, the formulation of prescription collections in medical institutions, and the clinical use of CPM, constituting an important part of traditional Chinese medicine (TCM) guidelines. As a crucial part of Chinese drug supply guarantee system, CPM plays an important role in the treatment, prevention, and healthcare of many disease categories, whereas the application of CPM has problems of misuse and even abuse. To standardize the application of CPM, a research team at Zhejiang Chinese Medical University developed the Reporting Items for Practice Guidelines in Healthcare for Chinese Patent Medicines (RIGHT for CPM) based on the RIGHT checklist framework. The RIGHT for CPM checklist gathers key information from published CPM guidelines, existing TCM reporting checklists, and the RIGHT checklist and its extensions to form an initial pool of reporting items. Seventeen experts from different disciplines were invited to conduct two rounds of Delphi surveys, and the final checklist was reviewed and approved for publication by 18 leading experts in TCM research and guideline reporting from China and abroad. The RIGHT for CPM checklist adds 16 sub-items and revises 2 sub-items on the basis of the RIGHT checklist, highlighting the characteristics of CPM guideline reporting. It considers CPM selection and inclusion criteria, policy access, indications and symptoms, drug combination instructions, drug use in special populations, precautions, and recommendations of Western medical physicians, among others. This can further improve the quality and transparency of CPM guideline reporting, promote standardized reporting of CPM guidelines, and facilitate the rational clinical use of CPM. This article interprets the development process of the RIGHT for CPM checklist and the items that highlight the characteristics of CPM guidelines, with a view to promoting the application of the RIGHT for CPM checklist.

Aim To evaluate the hypolipidemic effect of the total phenylpropanoid glycosides extracted from Ligustrum robustum (Roxb.) Blume (LRTPG) on hyperlipidemic golden hamsters and explore its regulatory effect on intestinal flora. Methods Sixty hamsters were randomly divided into a control group, a model group, a positive drug group, LRTPG-L group, LRTPG-M group, and LRTPG-H group. After the successful induction of the model by high-fat diet, the animals were continuously administered for four weeks, and their blood lipids and liver lipids were detected. The formed feces from the colorectal region of the hamsters in the control group, model group and LRTPG-H group were collected for 16S rDNA sequencing. Results LRTPG reduced serum TG, TC, LDL-C and liver TG, TC concentrations significantly in hyperlipidemic hamsters. The results of the intestinal microbiota sequencing showed that compared to the control group, LRTPG significantly decreased the relative abundance of the phylum Firmicutes and increased the relative abundance of the phylum Bacteroidetes and Verrucomicrobia (P < 0.01) at the phylum level. At the family level, LRTPG significantly increased the relative abundance of Christensenellaceae, Peptococcaceae, and Verrucomicrobiaceae (P < 0.05 or P < 0.01). At the genus level, LRTPG significantly increased the relative abundance of Oscillospira, Oscillibacter, Flavonifractor and Akkermansiaceae (P < 0.05 or P < 0.01). These changes in the flora were beneficial to the hypolipidemic effect of LRTPG. Conclusion LRTPG may exert its hypolipidemic effect by improving the intestinal flora disorder caused by a high-fat diet in golden hamsters.

Objective:
To compare the effectiveness of qualitative and quantitative fecal immunochemical tests (FIT) in identifying colorectal cancer, so as to provide insights into perfecting screening strategies for colorectal cancer.
Methods:
Participants in the Colorectal Cancer Screening Program for Key Populations in Zhejiang Province from May 2020 to December 2021 were recruited, and their demographic information, lifestyle and disease history were collected through a questionnaire survey. Qualitative or quantitative FIT along with a questionnaire-based risk assessment were employed as the initial screening tests. Individuals who were positive in any FIT or had high-risk assessment results were required to attend a subsequent colonoscopy examination. The positive rate, detection rate of colorectal cancer, positive predictive value and number of colonoscopies required were compared between qualitative and quantitative FITs, and stratified analyses by gender and age were conducted.
Results:
Totally 4 099 769 participants were included. The qualitative FIT group included 3 574 917 individuals, yielding a positive rate of 11.35%, a detection rate of 1.19%, a positive predictive value of 0.48% and 83.84 colonoscopies required to detect one cancer case. The quantitative FIT group involved 524 852 individuals, yielding a positive rate of 6.70%, a detection rate of 2.31%, a positive predictive value of 1.01% and 43.23 colonoscopies required to detect one cancer case. The quantitative FIT group showed significantly higher detection rate of colorectal cancer, higher positive predictive value and less number of colonoscopies required compared to the qualitative FIT group (all P<0.05). The same results were obtained after stratification by gender and age.
Conclusion
Compared to qualitative FIT, quantitative FIT improves the detection of colorectal cancer and reduces the workload of colonoscopy examinations, making it more suitable for colorectal cancer screening in large-scale populations.

Objective:To investigate the effects and mechanisms of zinc ion-loaded composite hydrogel (hereinafter referred to as the zinc-containing hydrogel) on infected full-thickness skin defect wounds in diabetic mice.Methods:This study was an experimental study. A poly (glycerol sebacate)-co-poly(ethylene glycol)-g-catechol prepolymer/quaternized-chitosan hydrogel (hereinafter referred to as the simple hydrogel) and a solid-state zinc-containing hydrogel with porous and good adhesion by adding zinc ions to the simple hydrogel were prepared. The release rate of zinc ions from the zinc-containing hydrogel after immersion in phosphate buffer solution (PBS) for 14 days was calculated. The concentration of methicillin-resistant Staphylococcus aureus (MRSA) cultured for 2 hours with the simple hydrogel, zinc-containing hydrogel, and PBS was measured. The scavenging ability of the simple hydrogel, zinc-containing hydrogel, and PBS for 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2, 4, 6-trinitrophenyl) hydrazyl (DPPH) was detected using microplate reader to reflect the ability of oxygen free radical removal. The length of vessels formed by human umbilical vein endothelial cells (HUVECs) cultured for 24 hours with the simple hydrogel, zinc-containing hydrogel, and PBS was measured. The cell viability of L929 cells cultured for 24 hours with the simple hydrogel, zinc-containing hydrogel, and PBS was detected using the cell counting kit-8. The mouse red blood cell suspension was divided into blank control group treated with PBS, simple hydrogel group, zinc-containing hydrogel group, and Triton X-100 group treated with corresponding solution. Hemolysis was detected using microplate reader after 2 hours of treatment, and the hemolysis rate was calculated. All experiments had a sample size of 3. Twenty-one C57BL/6J mice aged 6-8 weeks were taken, and a full-thickness skin defect wound was prepared in the symmetrical position on the back spine and infected with MRSA. Mice were divided into blank control group treated with PBS, simple hydrogel group, and zinc-containing hydrogel group treated with the corresponding hydrogel. Three days after injury, bacterial concentration in the wounds were measured in all groups of mice ( n=4). On day 0 (immediately), 3, 7, and 14 after injury, the wound infection status of mice was generally observed and the wound healing rate was calculated ( n=5). Hematoxylin-eosin staining and Masson staining were used to detect new epithelium and collagen formation in the wounds of mice on day 14 after injury. Immunofluorescence staining was used to detect neovascularization and distribution of M2 macrophages in the wounds of mice. Results:After immersion for 14 days, the release rate of zinc ions of the zinc-containing hydrogel was (70.5±4.6)%. Compared with the zinc-containing hydrogel, the bacterial concentration was significantly increased after 2 hours of culture with PBS and the simple hydrogel ( P<0.05). The DPPH scavenging rate of the zinc-containing hydrogel was significantly higher than that of PBS and the simple hydrogel (with P values all <0.05). The length of vessels formed by HUVECs cultured for 24 hours with the zinc-containing hydrogel was significantly longer than that cultured with PBS ( P<0.05). Compared with PBS and the simple hydrogel, the cell viability of L929 cells cultured for 24 hours with the zinc-containing hydrogel was significantly higher ( P<0.05). After 2 hours of incubation, compared with that in Triton X-100 group, the hemolysis rate of red blood cells in blank control, simple hydrogel, and zinc-containing hydrogel groups was significantly reduced ( P<0.05); and the hemolysis rate of red blood cells in the latter three groups was similar ( P>0.05). On day 3 after injury, the bacterial concentration in the wounds of mice in zinc-containing hydrogel group was significantly lower than that in blank control and simple hydrogel groups (with P values all <0.05). From day 3 to day 14 after injury, the wounds of mice in all the three groups were gradually healing, and on day 14 after injury, the wounds of mice in the zinc-containing hydrogel group were basically healed. On day 7 after injury, the wound healing rate of mice in zinc-containing hydrogel group was (72.4±8.4)%, which was significantly higher than that of blank control and simple hydrogel groups, being (31.6±6.7)% and (44.7±5.4)%, respectively(with P values all< 0.05). On day 14 after injury, the wound healing rate of mice in zinc-containing hydrogel group was (92.7±4.3)%, which was significantly higher than (73.5±7.4)% in blank control group ( P<0.05). On day 14 after injury, compared with that in blank control and simple hydrogel groups, the newly formed epidermis in mice wound of zinc-containing hydrogel group was longer and thicker, with more collagen deposition, and a more abundant distribution of new vessels and M2 macrophages. Conclusions:The zinc-containing hydrogel exhibits good biocompatibility, oxygen free radical scavenging capacity, and antimicrobial effects both in vitro and in vivo, as well as angiogenic promotion capability. It can provide sustained release of zinc ions to promote re-epithelialization and collagen synthesis, thus enhancing the healing of infected full-thickness skin defect wounds in diabetic mice.
