Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.

This study primarily aimed to investigate the prevalence of human papillomavirus (HPV) and other common pathogens of sexually transmitted infections (STIs) in spermatozoa of infertile men and their effects on semen parameters. These pathogens included Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, Mycoplasma genitalium , herpes simplex virus 2, Neisseria gonorrhoeae, Enterococcus faecalis, Streptococcus agalactiae, Pseudomonas aeruginosa , and Staphylococcus aureus . A total of 1951 men of infertile couples were recruited between 23 March 2023, and 17 May 2023, at the Department of Reproductive Medicine of The First People's Hospital of Yunnan Province (Kunming, China). Multiplex polymerase chain reaction and capillary electrophoresis were used for HPV genotyping. Polymerase chain reaction and electrophoresis were also used to detect the presence of other STIs. The overall prevalence of HPV infection was 12.4%. The top five prevalent HPV subtypes were types 56, 52, 43, 16, and 53 among those tested positive for HPV. Other common infections with high prevalence rates were Ureaplasma urealyticum (28.3%), Ureaplasma parvum (20.4%), and Enterococcus faecalis (9.5%). The prevalence rates of HPV coinfection with Ureaplasma urealyticum, Ureaplasma parvum, Chlamydia trachomatis, Mycoplasma genitalium , herpes simplex virus 2, Neisseria gonorrhoeae, Enterococcus faecalis, Streptococcus agalactiae , and Staphylococcus aureus were 24.8%, 25.4%, 10.6%, 6.4%, 2.4%, 7.9%, 5.9%, 0.9%, and 1.3%, respectively. The semen volume and total sperm count were greatly decreased by HPV infection alone. Coinfection with HPV and Ureaplasma urealyticum significantly reduced sperm motility and viability. Our study shows that coinfection with STIs is highly prevalent in the semen of infertile men and that coinfection with pathogens can seriously affect semen parameters, emphasizing the necessity of semen screening for STIs.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Aesculus chinensis is an important medicinal and horticultural plant. Its dried mature seeds, known as "Suoluozi", are a well-known traditional Chinese medicine. Aescins are its main active components, possessing multiple pharmacological activities such as anti-inflammatory and anti-exudative effects. They are widely used in the treatment of diseases such as lumbar disc herniation, postoperative edema, and sports injuries, leading to a continuous increase in market demand in recent years. The DNA binding with one finger(Dof) family is a unique transcription factor family found in the plant kingdom. It plays a crucial role in plant growth, development, stress responses, and regulation of secondary metabolism. However, research on the Dof gene family in A. chinensis is relatively scarce. In this study, we identified 36 AcDof genes from the genome of A. chinensis and analyzed their physicochemical properties, chromosomal localization, phylogenetic relationships, gene structures, cis-acting elements, and expression patterns in different tissues. The results showed that AcDof proteins ranged from 81 to 493 amino acids in length, with molecular weights ranging from 9 270.38 to 55 015.68 and isoelectric points ranging from 4.84 to 10.2. The subcellular localization analysis revealed that 34 AcDof proteins were located in the nucleus, while the remaining two AcDof proteins were located in the chloroplasts. Phylogenetic analysis divided AcDofs into nine subgroups, and gene structure analysis indicated that all AcDof genes possessed a C2-C2 type single zinc finger domain. Gene expression analysis using transcriptome data revealed tissue-specific expression patterns among AcDof family members. Specifically, AcDof04, AcDof02, and AcDof03 exhibited specific expression in seeds, suggesting their potential involvement in the regulation of aescin biosynthesis. This study not only enhances our understanding of the Dof gene family in A. chinensis but also provides important genetic resources for further investigation of the functions and regulatory mechanisms of Dof genes in this species.

AIM: To compare the accuracy of different intraocular lens(IOL)calculation formulas in cataract patients with axial length longer than 28mm and a history of radial keratotomy(RK).METHODS: Retrospective study. The medical records of 19 cataract patients(29 eyes)after RK and with axial length longer than 28mm who underwent cataract surgery from January 2011 to July 2020 in Beijing Tongren Hospital were analyzed. The absolute error(AE)of the difference among three different formulas was calculated. AE refers to the absolute value between the actual spherical equivalent after cataract surgery and the spherical equivalent predicted by the IOL formula. The AE values of the three formulas and the percentages of eyes with AE≤0.5, 0.75, 1.0, and 2.0D were calculated and compared.RESULTS: The AE values of the three formulas were significantly different(χ2=8.759, P=0.013). The Barrett True-K formula had the smallest median AE, which was only 0.62(0.20, 1.15)D, followed by the Haigis formula 0.76(0.34, 1.26)D, and the Holladay 1(D-K)formula had the largest 1.01(0.49, 1.62)D. The percentages of affected eyes with AE ≤0.5, 0.75, 1.0, and 2.0D for the Barrett True-K formula were 48%, 59%, 69%, and 93%, which were equal to or higher than the other two formulas.CONCLUSION: The Barrett True-K formula is more recommended among the three formulas for cataract patients after RK and with axial length longer than 28 mm.

Serum samples were tested for IgG antibodies using indirect immunofluorescence assays. We then analyzed associated risk factors. Serum samples were considered positive when reactive at a dilution of more than 1:320. Differences between groups and risk factors associated with exposure were statistically analyzed using Chi-square tests and the generalized linear model. 122 of 1,260 samples (9.68%) were positive for infection. The infection rate ranged from 0% to 30.43% and differed significantly among age groups ( < 0.01); infection rate in the 50-59 years group was significantly higher than that in other age groups. The seroprevalence of varied significantly among sites within the four provinces, and the infection rate of field workers was significantly higher than that of urban workers.

Objective::To investigate the protective effect of modified Yinchenhao Tang on α-isothiocyanate(ANIT)-induced cholestatic liver disease (CSLD). Method::Wistar rats were randomly divided into 7 groups: blank control group, model control group, compound Glycyrrhizin capsules group(22.5, 45 mg·kg^-1), modified Yinchenhao Tang low, middle and high dose groups(4.1, 8.1, 16.2 g·kg^-1). A model of cholestatic liver injury was prepared by intragastric administration of ANIT (100 mg·kg^-1). Glycyrrhizin capsules and modified Yinchenhao Tang were administered intragastrically on the second day of modeling for 4 consecutive days. And bile duct intubation was performed on the fifth day to measure the bile flow rate of the rats, and serum was taken to test the total bilirubin(TBIL), direct bilirubin(DBIL), indirect bilirubin(IBIL), alanine aminotransferase(ALT) and total bile acid(TBA) serological indicators of each group. Pathological changes of liver tissues were observed by hematoxylin-eosin (HE) staining. The expression levels of G protein-coupled bile acid receptor(TGR5), nucleotide binding oligomerization domain-like receptor 3(NLRP3) and cysteinyl aspartate specific proteinase-1(Caspase-1) proteins in the iver tissues were detected by Western blot. Result::Compared with the blank control group, bile flow rate in the model group decreased significantly(P<0.01). TBIL, DBIL, IBIL, ALT and TBA level in serum were significantly increased(P<0.01), liver tissue lesions were severe, and significantly increased the expression of liver tissue TGR5 and Caspase-1.Compare with model group, the compound Glycyrrhizin capsules group had no significant effect on bile flow rate and TBIL, DBIL, IBIL, ALT and TBA level in serum. Bile flow rate increased and TBIL, DBIL, IBIL, ALT and TBA level in serum decreased significantly in modified Yinchenhao Tang high dose group. The compound Glycyrrhizin capsules group and modified Yinchenhao Tang group have different extents of improvement the pathological changes of the lung tissues, and the protein expression of TGR5 and Caspase-1 were significantly decreased in the liver tissue(P<0.01). Conclusion::Modified Yinchenhao Tang can effectively treat CSLD in rats, and its mechanism may be related to bile acid and bile acid receptor TGR5-mediated inflammatory factors.
