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.

OBJECTIVES: To investigate the clinicopathological characteristics and prognostic factors of pediatric Hodgkin lymphoma (HL). METHODS: A retrospective analysis was conducted on the clinical data of children with newly diagnosed HL from January 2011 to December 2023 at four hospitals: Fujian Medical University Union Hospital, Fujian Medical University Zhangzhou Hospital, First Affiliated Hospital of Xiamen University, and Fujian Children's Hospital. Patients were categorized into low-risk (R1), intermediate-risk (R2), and high-risk (R3) groups based on HL staging and pre-treatment risk factors. The patients received ABVD regimen or Chinese Pediatric HL-2013 regimen chemotherapy. Early treatment response and long-term efficacy were assessed, and prognostic factors were analyzed using the Cox proportional hazards regression model. RESULTS: The overall complete response (CR) rates after 2 and 4 cycles of chemotherapy were 42% and 68%, respectively. Compared with the ABVD regimen group, patients treated with the HL-2013 regimen in the R1 group showed significantly higher CR rates after both 2 and 4 cycles (P<0.05). However, no statistically significant differences in CR rates were observed between the two regimens in the R2 and R3 groups (P>0.05). The 5-year event-free survival (EFS) rate, overall survival rate, and freedom from treatment failure rate were 83%±4%, 97%±2%, and 88%±4%, respectively. Cox analysis indicated that the presence of a large tumor mass at diagnosis and failure to achieve CR after 4 cycles of chemotherapy were independent risk factors for lower EFS rates (P<0.05). CONCLUSIONS Pediatric HL generally has a favorable prognosis. The presence of a large tumor mass at diagnosis and failure to achieve CR after 4 cycles of chemotherapy indicate poor prognosis.

OBJECTIVE: Poxviruses are zoonotic pathogens that infect humans, mammals, vertebrates, and arthropods. However, the specific role of ticks in transmission and evolution of these viruses remains unclear. METHODS: Transcriptomic and metatranscriptomic raw data from 329 sampling pools of seven tick species across five continents were mined to assess the diversity and abundance of poxviruses. Chordopoxviral sequences were assembled and subjected to phylogenetic analysis to trace the origins of the unblasted fragments within these sequences. RESULTS: Fifty-eight poxvirus species, representing two subfamilies and 20 genera, were identified, with 212 poxviral sequences assembled. A substantial proportion of AT-rich fragments were detected in the assembled poxviral genomes. These genomic sequences contained fragments originating from rodents, archaea, and arthropods. CONCLUSION Our findings indicate that ticks play a significant role in the transmission and evolution of poxviruses. These viruses demonstrate the capacity to modulate virulence and adaptability through horizontal gene transfer, gene recombination, and gene mutations, thereby promoting co-existence and co-evolution with their hosts. This study advances understanding of the ecological dynamics of poxvirus transmission and evolution and highlights the potential role of ticks as vectors and vessels in these processes.

OBJECTIVE To explore the therapeutic effect and safety of Maiwei Yangfei Decoction(MWYF)in the treatment of idiopathic pulmonary fibrosis of qi-yin deficiency type.METHODS A total of 58 patients with idiopathic pulmonary fibrosis of qi-yin deficiency type were randomly divided into an experimental group and a control group with 29 cases in each group according to a 1:1 ratio.Two cases dropped out of the experimental group and three cases dropped out of the control group.The control group received standardized treatment of Western medicine,and the experimental group received MWYF on the basis of the treatment of the control group.The treatment course of both groups was 3 months.The TCM syndrome score,lung function,6-minute walking distance(6MWD),transcutaneous blood oxygen saturation(SpO2),high-resolution computed tomography(HRCT)score,St.George's respir-atory questionnaire(SGRQ)score and serum sialoglycoprotein antigen(KL-6)level of the two groups were compared before and after treatment.Blood routine and liver and kidney function of the two groups were detected before and after treatment,and the occurrence of adverse reactions during treatment was recorded.RESULTS After treatment,the total score of TCM syndrome of the two groups was significantly improved(P<0.01),and the experimental group was better than the control group(P<0.01);the DLCO%of the experi-mental group increased(P<0.05),and the experimental group was higher than the control group(P<0.05).The experimental group showed significant improvement in 6MWD,HRCT grid shadow,SGRQ symptom score and total score,and serum KL-6 level(P<0.05,P<0.01),which was better than the control group(P<0.05,P<0.01).No serious adverse events occurred in either group dur-ing the treatment.CONCLUSION MWYF combined with standardized Western medicine treatment can effectively improve the clini-cal symptoms of patients with idiopathic pulmonary fibrosis of qi-yin deficiency type,reduce the expression level of serum KL-6,and has a definite effect and good safety.

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.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the safety and efficacy of four-hook needle combined with holographic image in robot-assisted partial nephrectomy for completely intrarenal tumors.Methods:The clinical data of 8 patients with completely intrarenal tumors treated by robot-assisted partial nephrectomy with four-hook needle combined with holographic image admitted to General Hospital of Central Theater Command from October 2023 to December 2023 were retrospectively analyzed. There were 6 males and 2 females, with average age of (44.5±12.0) years old. Tumors of 6 cases were in the left side and 2 cases in the right side. The maximum diameter of the tumor was (23.2±8.1) mm. The R. E.N.A.L. score was (9.0±1.4). The preoperative serum creatinine (Scr) was (73.1±14.7) μmol/L. CT-guided four-hook needle was used to locate the edge of completely intrarenal tumor before surgery. During the operation, the tumor was precisely resected under the guidance of hologram and four-hook needle. Perioperative data of patients were collected and analyzed.Results:All the tumor were successfully resected under the guidance of four-hook needle and hologram without conversion to radical nephrectomy or open surgery. The mean operative time was (117.0±14.5) min, the mean hot ischemia time was (20.2±5.1) min, the mean intraoperative blood loss was (75.0±17.3) ml, and the average hospitalization time was (9.5±1.3) days.The one week postoperative Scr was (73.2±14.8) μmol/L, which had no significant difference with that of before operation ( P=0.952). None of them received blood transfusion. The pathology results of 8 patients were clear cell renal cell carcinoma, and the surgical margins were negative. Conclusions:For completely intrarenal tumors, the four-hook needle combined with the hologram can guide the surgeon to quickly locate the tumor, accurately resect the tumor, reduce perioperative complications, and is safe and effective.

A boy,aged 7 months,presented with severe global developmental delay(GDD),refractory epilepsy,hypotonia,nystagmus,ocular hypertelorism,a broad nasal bridge,everted upper lip,a high palatal arch,and cryptorchidism.Genetic testing revealed a de novo heterozygous missense mutation of c.364G>A(p.E122K)in the EEF1A2 gene,and finally the boy was diagnosed with autosomal dominant developmental and epileptic encephalopathy 33 caused by the EEF1A2 gene mutation.This case report suggests that for children with unexplained infancy-onset severe to profound GDD/intellectual disability and refractory epilepsy,genetic testing for EEF1A2 gene mutations should be considered.This is particularly important for those exhibiting hypotonia,nonverbal communication,and craniofacial deformities,to facilitate a confirmed diagnosis.

Objective Sequencing depth is a key parameter in next generation sequencing,which is closely related to the accuracy of sequencing results.Forensic biological evidence examination requires extremely high accuracy.It is crucial to scientifically and reasonably set the sequencing depth analysis threshold for forensic next generation sequencing testing.Methods This study used targeted sequencing data of microhaplotypes from 50 samples with known genotypes.By calculating the accuracy,precision,recall,and F1 score of each locus under various threshold conditions,two types of analysis threshold setting methods,which were based on fixed read count and fixed sequencing depth ratio,were studied extensively.Results The results showed that false positives were observed when the analysis threshold was set at 50×or 100×.When the analysis threshold was set at 200×,false negatives were observed.When the analysis threshold was set at 1.5%,3.0%,or 4.5%,false positives were observed.This study further proposed a third type of analysis threshold setting method,which was based on sequencing depth ratio scatter plots.With this method,no false positive or false negative was observed in the results.This article then explored four factors that lead to significant differences in the sequencing depth of forensic next generation sequencing experiments,compared with the analysis threshold setting method for capillary electrophoresis technology,and discussed the correlation between analysis thresholds and the ability to distinguish mixed DNA.Conclusion Employing the sequencing depth ratio scatter plot method to set analysis threshold has significant application value in next generation sequencing-based forensic genetic marker genotyping.

Objective Evaluation of the clinical efficacy of f trochanteric flip osteotomy combined with Kocher-Langen-beck approach for high acetabular posterior wall fracture.Methods Between January 2020 and December 2022,20 patients with high acetabular posterior wall fractures were retrospectively analyzed,including 12 males and 8 females,aged 18 to 75 years old.They were divided into two groups according to the different surgical methods.Ten patients were treated with greater trochanteric osteotomy combined with Kocher-Langenbeck approach as the observation group,including 5 males and 5 fe-males,aged from 18 to 75 years old.Ten patients were treated with Kocher-Langenbeck approach alone as the control group,including 7 males and 3 females,aged from 18 to 71 years old.Matta reduction criteria were used to evaluate the reduction quality of the two groups,and Harris score was used to compare the hip function of the two groups at the latest follow-up.The operation time,blood loss and postoperative complications of the two groups were analyzed.Results All patients were followed up for 10 to 24 months.According to the Matta fracture reduction quality evaluation criteria,the observation group achieved anatomical reduction in 6 cases,satisfactory reduction in 3 cases,and unsatisfactory reduction in 1 case,while the control group only achieved anatomical reduction in 3 cases,satisfactory reduction in 3 cases,and unsatisfactory reduction in 4 cases.At the final follow-up,the Harris hip score ranged from 71.4 to 96.6 in the observation group and 65.3 to 94.5 in the control group.According to the results of Harris score.The hip joint function of the observation group was excellent in 6 cases,good in 3 cases,and fair in 1 case.The hip joint function of the control group was excellent in 2 cases,good in 3 cases,fair in 3 cases,and poor in 2 cases.In the observation group,the intraoperative blood loss ranged from 300 to 700 ml,and the operation dura-tion ranged from 120 to 180 min;in the control group,the intraoperative blood loss ranged from 300 to 650 ml,and the opera-tion duration ranged from 100 to 180 min.Complications in the observation group included 1 case of traumatic arthritis and 1 case of heterotopic ossification,while complications in the control group included 3 cases of traumatic arthritis,3 cases of het-erotopic ossification and 1 case of hip abduction weakness.Conclusions Trochanteric flip osteotomy combined with the Kocher-Langenbeck approach significantly improved anatomical fracture reduction rates,enhanced excellent and good hip joint function outcomes,and reduced surgical complication incidence compared to the Kocher-Langenbeck approach alone.Clinical application of this combined approach is promising,although larger studies are needed for further validation.
