Objective To explore the growth and developmental parameters and behavioral characteristics of rhesus monkeys during the first year of birth and to establish the background data.Methods A total of 18 (♂=11,♀=7 ) infant rhesus monkeys born from individually caged mothers and with known genetic background and postnatal days were monitored monthly for body weight, body height, head circumference, chest circumference, forelimb length, hind limb length, crown-rump length, tail length and anal-genital distance from postnatal day ( PND) 1 to 360, while hematology, blood chemistry and lymphocyte subsets were examined on PND 28, 175 and 360, and finger maze test was carried out on PND 208.Results The body weight showed linear growth with no significant difference between genders (P>0.05). Except for the anal-genital distance of male infants was significantly greater than that of female infants ( P<0.01 ) , no significant differences were observed between sexes in other morphological parameters.No significant differences of hematology were seen between genders (P >0.05).Compared with that at PND28, TP and BUN were significantly increased (P<0.01) while ALP decreased with no significant difference (P>0.05) at PND 175 and 360.Compared with that at PND28, CD4 +and CD4 +/CD8 +were significantly decreased ( P<0.01) while CD8+significantly increased ( P<0.01) at PND175 and 360.The number of sessions to solve task 2 in learning test was significantly greater than other tasks with females significantly less than males ( P<0.05) .The females had higher correct rate than males in the 2-day random memory test (P<0.05).Conclusions Body weight and morphological parameters show a linear growth.The PND.The RBC, HGB, LYMPH, TP, BUN, ALP, CD4 +, CD8 +and CD4 +/CD8+in hematology, blood chemistry and lymphocyte subsets show relevant changes to the growth and development of organs and systems in infants, which should be highly concerned in drug evaluation.The finger maze test indicates that female infants have better reversal learning and long-term memory than male infants.Background data and behavioral characteristics of infant rhesus monkeys during the first 12 months of birth are established in this study, which provide useful reference and support the evaluation of developmental and reproductive toxicity of drugs in rhesus monkeys.

Objective:To evaluate the value of Treponema pallidum ( Tp)-specific antibody index in the diagnosis, staging, and typing of neurosyphilis (NS). Methods:Fifty patients diagnosed with NS at the West China Hospital of Sichuan University from March 2020 to December 2022 were recruited as the experimental group, and 50 non-NS syphilis patients were enrolled during the same period as the control group. Cerebrospinal fluid (CSF) and matched serum samples along with clinical data were collected. Clinical and Laboratory Standards Institute (CLSI) EP06-Ed2 file was used to analyze the linear range of electrochemiluminescence immunoassay for Tp-specific antibody detection, and the Tp antibody index was calculate for all subjects. The correlation of Tp antibody index, IgG index, IgG synthesis rate, and albumin quotient with other clinical indicators was evaluated by the coefficient of correlation, and the diagnostic efficacy of these indicators in NS was analyzed using the receiver operating characteristic (ROC) curve. Results:All the deviations from linearity of electrochemiluminescence immunoassay for detecting Tp antibodies in serum and CSF samples were within the allowable deviation from linearity. Compared with the non-NS group, the NS group showed a significant increase in the Tp antibody index ( P<0.05), with no significant differences observed among the groups of different subtypes, severity, or receiving treatment or not ( P>0.05). Tp antibody index, IgG index, and IgG synthesis rate were positively correlated with serum Tp antibody, CSF Tp antibody, trace protein, and nucleated cell count ( P<0.05). Taking 14.99 as the cut-off value for NS diagnosis, the diagnostic sensitivity of Tp antibody index was 74.0% (95%CI: 60.5%-84.1%), and the specificity was 94.0% (95%CI: 83.8%-98.4%), with the area under the ROC curve of 0.897, which was larger than that of albumin quotient, IgG index, and IgG synthesis rate. Conclusions:This study finds a significant increase in the Tp antibody index in NS patients with good diagnostic sensitivity and specificity, providing reference for the diagnosis of NS.

The standardization of pediatric Tuina is beneficial to pediatric Tuina practitioners in a norm practices. The paper collects the content from teaching textbooks, TCM ancient books and database literature, and tries to develop the technical specifications of pediatric Tuina by four rounds Delphi surveys and expert consensus. This specification covers the manipulation of pediatric Tuina, the position of acupoints, the effects of acupoints and the diagnosis and treatment of pediatric Tuina, including indications, contraindications, cautious use, operation steps and methods.

In order to standardize the clinical diagnosis and treatment of upper airway cough syndrome (UACS) for children in China, Dongzhimen Hospital of Beijing University of Chinese Medicine and Affiliated Hospital of Liaoning University of Traditional Chinese Medicine initiated the development of this Traditional Chinese Medicine Diagnosis and Treatment Guidelines for Children with Upper Airway cough Syndrome based on evidence-based medical evidence. This guideline will process registration, write a plan, and develop relevant processes and writing norms, develop and publish official documents. This plan mainly introduces the scope of the guidelines, the purpose and significance, the composition of the guidelines working group, the management of conflicts of interest, the collection, selection and determination of clinical problems, the retrieval, screening and rating of evidence, and the consensus of recommendations. Registration information: This study has been registered in the international practice guidelines registry platform with the registration code of PREPARE-2023CN087.

Optimization efforts were devoted to discover novel PDE10A inhibitors in order to improve solubility and pharmacokinetics properties for a long-term therapy against pulmonary arterial hypertension (PAH) starting from the previously synthesized inhibitor

Anthocyanins are widely distributed water-soluble pigments that not only give the fruit colorful appearances, but also are important sources of natural edible pigments. In recent years, the interest on anthocyanins of solanaceous vegetables is increasing. This paper summarized the structure of anthocyanins and its biosynthetic pathway, the structural genes and regulatory genes involved in the biosynthesis of anthocyanins in solanaceous vegetables, as well as the environmental factors affecting the biosynthesis. This review may help clarify the synthesis and regulation mechanism of anthocyanins in solanaceous vegetables and make better use of anthocyanins for quality breeding of fruit colors.
