Compounds isolated from Epimedium include the total flavonoids of Epimedium , icariin, and its metabolites (icaritin, icariside I, and icariside II), which have similar molecular structures. Modern pharmacological research and clinical practice have proved that Epimedium and its active components have a wide range of pharmacological effects, especially in improving sexual function, hormone regulation, anti-osteoporosis, immune function regulation, anti-oxidation, and anti-tumor activity. To date, we still need a comprehensive source of knowledge about the pharmacological effects of Epimedium and its bioactive compounds on the male reproductive system. However, their actions in other tissues have been reviewed in recent years. This review critically focuses on the Epimedium , its bioactive compounds, and the biochemical and molecular mechanisms that modulate vital pathways associated with the male reproductive system. Such intrinsic knowledge will significantly further studies on the Epimedium and its bioactive compounds that protect the male reproductive system and provide some guidances for clinical treatment of related male reproductive disorders.

Objective To construct time-series by adopting autoregressive integrated moving average(ARIMA)model for analyzing the trend and genotype characteristics of single-center human papillomavirus(HPV)infection in Tianjin area.Methods A total of 7 236 female patients who underwent HPV testing in a hospital from January 2018 to December 2022 were selected.HPV infection status and genotype distribution in Tianjin area from 2018 to 2022 were compared.ARIMA model time-series was constructed,and model fitting was analyzed.The number of HPV infections in 2023 was predicted and compared with the actual occurrence,the predictive performance of the model was evaluated.Results HPV infection rate in Tianjin area from 2018 to 2022 was 14.41％,with the highest rate(15.47％)in the age group of 31-40 years.Among the positive specimens,the proportion of single type HPV infection was the highest,accounting for 73.54％(767/1 043),with high-risk HPV being the main type.The highest infection rates of low-risk and high-risk types were type HPV-6(2.59％)and type HPV-16(16.06％),re-spectively.ARIMA model was constructed,and the optimal model was ARIMA(0,1,2)(0,1,1)12,with akaike in-formation criterion(AIC)and bayesian information criterion(BIC)values of 3.877 and 4.005,respectively.There was no statistical significance in Ljung-Box Q=8.828 showed by white noise test(P＞0.05).The number of HPV infection in 2023 was predicted by the model.The overall trend of the actual value and the predicted value was basi-cally consistent,RMSE,MAPE and MAE of the model were 6.289,34.149 and 4.706,respectively,suggesting that the model had a good prediction effect.Conclusion Among the female population in Tianjin area,HPV infec-tion is mainly caused by single,high-risk type,with HPV-16 having the highest infection rate.There is seasonal variation in HPV infection in Tianjin.ARIMA model has good prediction effect on the prevalence trend of HPV in-fection,which is suitable for short-term prediction.

Objective To analyze the risk of adverse drug events in pediatric clinical applications of tocilizumab versus inflixima.Methods Adverse event(AE)reporting data for tocilizumab versus infliximab in the U.S.Food and Drug Administration Adverse Event Reporting System database for the pediatric population from Q1 2013 to Q1 2023 were collected.AE risk signal mining was performed using the reporting odds ratio(ROR)method and the proportional reporting ratio(PRR)method.AEs were also classified and statistically analyzed according to the preferred system organ classification and preferred terminology(PT)of the International Dictionary of Medical Terminology.Results Data were extracted and cleaned to include 1 052 AE reports with 198 positive PT signals for tocilizumab as the suspected drug and 9 1 39 AE reports with 387 positive PT signals for infliximab as the suspected drug.The analyses suggested that the stronger positive risk signals for both drugs were focused on gastrointestinal disorders,infectious and invasive diseases,laboratory tests,musculoskeletal and connective tissue disorders,and blood,vascular,and lymphatic disorders.The risk signals for infliximab were focused on gastrointestinal disorders,infections,and infectious diseases,while the risk signals for tocilizumab were focused on the musculoskeletal muscle system.Conclusion Clinical use of both drugs in children has multi-system effects,tocilizumab may have effects on growth and development,and infliximab has effects on the gastrointestinal tract in children.

Anthocyanidin reductase (ANR) is one of the key enzyme in the flavonoid biosynthetic pathway, and its catalytic activity is important for the synthesis of plant anthocyanin. In this study, specific primers were designed according to the transcriptome data of Lonicera japonica Thunb., and the CDS, gDNA and promoter sequences of ANR genes from Lonicera japonica Thunb. and Lonicera japonica Thunb. var. chinensis (Wats.) Bak. were cloned. The results showed that the CDS sequences of LjANR and rLjANR were 1 002 bp, the gDNA sequences were 2 017 and 2 026 bp respectively, and the promoter sequences were 1 170 and 1 164 bp respectively. LjANR and rLjANR both contain 6 exons and 5 introns, which have the same length of exons and large differences in introns. The promoter sequences both contain a large number of light response, hormone response and abiotic stress response elements. Bioinformatics analysis showed that both LjANR and rLjANR encoded 333 amino acids and were predicted to be stable hydrophobic proteins without transmembrane segments and signal peptides. The secondary structures of LjANR and rLjANR were predicted to be mainly consisted of α-helix and random coil. Sequence alignment and phylogenetic analysis showed that LjANR and rLjANR had high homology with Actinidia chinensis var. chinensis, Camellia sinensis and Camellia oleifera, and were closely related to them. The expression levels of LjANR and rLjANR were the highest in flower buds and the lowest in roots. The expression patterns at different flowering stages were similar, with higher expression levels in S1 and S2 stages and then gradually decreased until reaching the lowest level in S4 stage, after a slow increase in S5 stage, the expression levels decreased again. The expression levels of ANR genes in the two varieties showed significant differences in roots, S2 and S5 stages, while the differences in stems, flower buds, S1, S3 and S6 stages were extremely significant. The prokaryotic expression vector pET-32a-LjANR was constructed for protein expression. The target protein was successfully expressed of about 59 kD. This study lays a foundation for further study on the function of ANR gene and provides theoretical guidance for breeding new varieties of Lonicera japonica Thunb.

Objective: To evaluate the association between pre-and post-diagnosis body mass index (BMI) and risk of colorectal cancer (CRC) death. Methods: The cohort consisted of 3, 057 CRC patients from Shanghai who were diagnosed from Jan. 1, 2009 to Dec. 31, 2011 and aged from 20 to 74 years. The pre- and post-diagnosis BMI and clinical and lifestyle factors were collected at baseline. Death information was collected using record linkage with the Shanghai Cancer Registry and telephone confirmation during follow-up by the end of 2019. The Cox proportional regression model was used to estimate HR with 95% CI. Results: Analysis by multivariable Cox model showed no association between pre-diagnosis BMI and death risk in both male and female patients. Male patients with a post-diagnosis underweight BMI had an elevated risk of death compared to those in normal weight (HR=1.69, 95% CI: 1.21-2.37), especially in early stage cases. Overweight patients (HR=0.74, 95% CI: 0.61-0.89) and patients with obesity class Ⅰ (HR=0.63, 95% CI: 0.45-0.89)had better survival with decreased risks of death, especially in advanced stage cases. The decreased death risk in patients with obesity class Ⅱ was not significant (HR=0.57, 95% CI: 0.24-1.39). The P(trend) value for decreased risk of death with increased BMI in female patients was statistically significant (P<0.001), and the overweight and obesity class Ⅰ categories had better survival in advanced stage(HR(overweight)=0.62, 95% CI: 0.42-0.93; HR(obesity class Ⅰ)=0.39, 95% CI: 0.16-0.98). Both male and female patients with post-diagnosis BMI loss >2.0 kg/m(2) had an increased death risk when compared with those with stable BMI (change≤1.0 kg/m(2)) between pre- and post-diagnosis. BMI gain after diagnosis did not change death risk. Conclusions: Post-diagnosis BMI in the overweight or obesity class Ⅰ groups might be conducive to prolonging male CRC patients' survival, while underweight might result in poor prognosis. Keeping weight and avoiding excessive weight loss should be suggested for all CRC patients after diagnosis.

OBJECTIVES: To study the expression level of plasma miR-106b-5p in primary immune thrombocytopenia (ITP) and its correlation with the levels of T helper 17 cell (Th17) and regulatory T cell (Treg) and the Th17/Treg ratio. METHODS: A total of 79 children with ITP (ITP group) and 40 healthy children (control group) were selected as subjects. According to the treatment response, the 79 children with ITP were divided into three groups: complete response (n=40), partial response (n=18), and non-response (n=21). Quantitative real-time PCR was used to measure the expression level of miR-106b-5p. Flow cytometry was used to measure the frequencies of Th17 and Treg, and the Th17/Treg ratio was calculated. The correlation of the expression level of plasma miR-106b-5p with the frequencies of Th17 and Treg and the Th17/Treg ratio was analyzed. RESULTS: Compared with the control group, the ITP group had significantly higher levels of miR-106b-5p, Th17, and Th17/Treg ratio (P<0.05) and a significantly lower level of Treg (P<0.05). After treatment, the ITP group had significant reductions in the levels of miR-106b-5p, Th17, and Th17/Treg ratio (P<0.05) and a significant increase in the level of Treg (P<0.05). Compared with the partial response and non-response groups, the complete response group had significantly lower levels of miR-106b-5p, Th17, and Th17/Treg ratio (P<0.05) and a significantly higher level of Treg (P<0.05). The correlation analysis showed that in the children with ITP, the expression level of plasma miR-106b-5p was positively correlated with the Th17 level and the Th17/Treg ratio (r=0.730 and 0.816 respectively; P<0.001) and was negatively correlated with the Treg level (r=-0.774, P<0.001). CONCLUSIONS A higher expression level of miR-106b-5p and Th17/Treg imbalance may be observed in children with ITP. The measurement of miR-106b-5p, Th17, Treg, and Th17/Treg ratio during treatment may be useful to the evaluation of treatment outcome in children with ITP.

UDP-glucose: flavonoid 3-O-glucosyltransferase (UF3GT) uses flavones, dihydroflavonol or anthocyanin as the acceptor and uridine 5′-diphosphate-sugar as the donor to catalyze the production of flavonoid 3-O-glycoside compounds. Based on sequence homology and transcriptome data, we screened and cloned a UF3GT gene named CtUF3GT (GenBank No. OM948976) from safflower. Biological information analysis demonstrate that CtUF3GT has highly conserved PSPG motif. The open reading frame of CtUF3GT is 1 446 bp, encoding 481 amino acids, with a presumed molecular weight of 52.36 kD and a theoretical isoelectric point of 5.33. Multiple sequence alignment indicate that CtUF3GT has a high homology with UF3GT from Asteraceae, and phylogenetic analysis showed that CtUF3GT clusters with functional identified UF3GTs from other species. The purified recombinant protein glucosylated kaempferol and quercetin to biosynthesis of kaempferol 3-O-glucoside and quercetin 3-O-glucoside, respectively. And CtUF3GT prefered to use kaempferol as substrate. qRT-PCR analysis showed that the UF3GT gene was most highly expressed in flowers, followed by leaves, with very low expression in bracts and stems, and no expression in roots. The expression of UF3GT gene showed a trend of increasing and then decreasing at different stages of flower development. The expression of CtUF3GT gene in safflower with different flower color was highly significant (P < 0.01) at S1, S2, S5, S6 and S7 stages of flower development, in which the expression of CtUF3GT in white safflower was 5.3 and 3.1 times higher than that in red safflower at S6 and S7 stages. This study lays the foundation for further exploring the role of CtUF3GT in the mechanism of safflower flavonoid secondary metabolite biosynthesis and accumulation.

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.
