To investigate the distribution and development of common allergens in children in Hangzhou area, and to provide an epidemiological basis for the prevention, diagnosis, and treatment of allergic diseases in this area. This study is a retrospective study, selecting 3 524 children who underwent allergen screening at DiAn Medical Laboratory Center (Hangzhou) Co., Ltd. from January 2022 to January 2024 as the research subjects, including 2 012 males and 1 512 females. Among them, there were 1 098 infants (0-1 year olds), 1 673 toddlers (1-3 year olds), and 753 children (3-14 year olds). Immunoblotting was used to detect 21 allergen-specific immunoglobulin E (sIgE) antibodies. The positive rates of various allergens were calculated according to gender, age, and other factors, and the epidemiological characteristics and trends were analyzed. The results showed that the overall positive rate of sIgE was 60.33% (2 126/3 524). The main inhaled allergens were Dermatophagoides pteronyssinus/Dermatophagoides farinae (992, 28.15%), dog dander (295, 8.37%) and cat dander (181, 5.13%). The main food allergens were milk (696, 19.75%), egg white (541, 15.36%) and shrimp (205, 5.83%). Boys had significantly higher sIgE positivity rates than girls for Dermatophagoides pteronyssinus/Dermatophagoides farinae(642, 31.90%, χ2=10.10, P=0.001), house dust(61, 3.02%, χ2=5.12, P=0.024), cat dander(124, 6.16%, χ2=4.06, P=0.044), mold combinations(103, 5.14%, χ2=7.51, P=0.006), and tree pollen combinations(42, 2.07%, χ2=5.44, P=0.020) (all P<0.05); With age, there was a significant increase in positivity rates for house dust mite/dust mite, house dust, mold combinations, milk, and beef (all P<0.05), and a significant decrease in positivity rates for cockroach consumption, egg whites, shrimp, crab, cod, lobster/scallop, and soybeans (all P<0.05), the positive rates of only ingestive allergens decreased significantly ( P<0.001), and the positive rates of only inhalant and mixed allergens increased significantly ( P<0.001). In conclusion,in the Hangzhou area, dust mites are the most common inhalant allergens among children with allergic diseases, while milk is the most common food allergen. Boys are more sensitive to inhalant allergens, and as children grow older, the positive rates for different allergens undergo significant changes. Dynamic monitoring of changes in specific IgE antibodies to various allergens can assist in the diagnosis, prevention, and treatment of allergic diseases.

In recent years，with the change in lifestyle and social environment and the increase in pressure in both life and work，male fertility has decreased significantly in China，and the incidence of male infertility has increased year by year，which has brought great challenges to andrologists. Traditional Chinese medicine （TCM） has a definite curative effect in the treatment of male infertility and is widely applied in clinical practice. In order to clarify the role of TCM in different types and each stage of male infertility，the China Association of Chinese Medicine （CACM） invited outstanding young andrologists in the clinic of TCM and western medicine to discuss topics such as idiopathic oligospermia and teratospermia，abnormal semen liquefaction，varicocele，immune infertility，improving success ratio of assisted reproductive technology，and ameliorating depression or anxiety. They conducted in-depth discussions on the advantages，characteristics，disadvantages，diseases responding specifically，and advantageous aspects of TCM treatment. The causes of male infertility and related links of treatment were summarized. Due to the unclear etiology and complex pathogenesis of male infertility，western medicine cannot achieve a good curative effect，while TCM，taking the holistic view as the core，specializes in improving functional diseases and can correspond to multiple targets and factors，with comprehensive treatments such as internal treatment and external treatment. This study summarized the advantageous diseases and advantageous stages of TCM treatment alone and integrated TCM and western medicine treatment and put forward suggestions for the treatment of the diseases by TCM and western medicine in order to promote the therapeutic effects and advantages of TCM among andrologists，increase mutual learning and communication between TCM and western physicians，provide patients with excellent and personalized treatment plans in clinical practice，and improve the curative effect of male infertility and fertility of males in China.

Objective To investigate the expression levels of microRNA(miR)-191,miR-23a,and miR-145 in plasma of patients with prostate cancer and their correlation with prognosis.Methods Sixty prostate cancer patients admitted to Zhumadian Central Hospital from December 2019 to December 2021 were selected as the observation group,and 60 healthy subjects who underwent physical examinations during the same period were selected as the control group.The expression levels of miR-191,miR-23a and miR-145 in plasma of subjects in the two groups were measured by real-time fluorescence quantita-tive polymerase chain reaction.The patients in the observation group were divided into poor prognosis group(n=11)and good prognosis group(n=49)according to their prognosis.The expression levels of miR-191,miR-23a,and miR-145 in plasma of prostate cancer patients were compared before and after treatment.The general data of patients was compared between the poor prognosis group and the good prognosis group.The receiver operator characteristic curve was drawed to analyse the predictive value of plasma miR-191,miR-23a,and miR-145 levels on prognosis.Results The relative expression levels of miR-191 and miR-23 a in plasma of patients in the observation group were significantly higher than those in the control group,while the relative expression level of miR-145 was significantly lower than that in the control group(P＜0.05).The relative expression levels of miR-191 and miR-23a of patients in the observation after treatment were significantly lower than those before treat-ment,while the relative expression level of miR-145 was significantly higher than that before treatment(P＜0.05).There was no significant difference in age,body mass index,smoking history,alcohol consumption history,and prostate volume of patients between the poor prognosis group and the good prognosis group(P＞0.05);there was significant differences in TNM staging,Gleason score,serum prostate specific antigen level and relative expressions of miR-191,miR-23a,miR-145 in plasma of patients between the two groups(P＜0.05).Plasma miR-191,miR-23a and miR-145 levels were influence factor for prognosis in patients with prostate cancer(P＜0.05).There was predictive value of plasma miR-191,miR-23a and miR-145 for prognosis of prestate cancer patients;the combined predictive value of plasma miR-191,miR-23a and miR-145 for the prognosis of prostate cancer patients was significantly higher than that of plasma miR-191,miR-23a and miR-145 alone for the prognosis of prostate cancer patients(P＜0.05).Conclusion The expression of miR-191 and miR-23a in plasma increases and the expression of miR-145 in plasma decreases in patients with prostate cancer.The combined detection of plasma miR-191,miR-23a and miR-145 has higher predictive value for the prognosis of prostate cancer.

Objective To investigate the effect of sinomenine on the purinergic receptors A2A and P2X7 in endotoxemia mouse model and RAW264.7 macrophage model stimulated by lipopolysaccharide(LPS). Methods BALB/c mice were randomly divided into blank control group, model group and sinomenine group. Thirty minutes after the rats of sinomenine group were pretreated with intraperitoneal injection of sinomenine (40, 80, 160 mg/kg), the mice were given intraperitoneal injection of 15 mg/kg LPS to induce endotoxemia model. The serum levels of tumor necrosis factor-alpha(TNF-α) and interleukin-6(IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). The expression levels of purinergic receptor A2A and P2X7 in the liver and spleen were detected by reverse transcription-polymerase chain reaction(RT-PCR). RAW264.7 macrophages were divided into blank control group, LPS group and sinomenine group. Sinomenine group was firstly treated with sinomenine(300μmol/L) for 2 h, and then LPS group and sinomenine group were treated with LPS (100 ng/mL) for another 8 hours. TNF-α in the cell supernatant was measured by ELISA, and the expression levels of A2A and P2X7 in RAW264.7 cells were detected by RT-PCR. Results Stimulation with LPS could induce the increase of the mouse serum levels of TNF-α and IL-6 as well as the expression of A2A and P2X7 in mouse liver and spleen, and sinomenine had a counteraction on the above indexes(P<0.05) . In-vitro stimulation with LPS could induce the increase of the content of TNF-α and the expression of A2A and P2X7 in RAW264.7 cells , and sinomenine decreased TNF-α content and P2X7 expression (P<0.05) , but had an effect on enhancing A2A expression. Conclusion Sinomenine suppresses the expression of purinergic receptor P2X7 in mouse spleen and liver as well as in RAW264.7 macrophages, but its effect on the expression of A2A in various tissues and cells varies, whose related mechanism is needed further study.
