ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Objective: To analyze the expressions of coordinated stimulating molecular programmed death 1(PD-1) and programmed death ligand 1 (PD-L1) in human glioma and their clinical significances. Methods: A total of 70 postoperative paraffin specimens of brain glioma and 35 normal brain tissues in Heji Hospital Affiliated to Changzhi Medical College from January 2013 to December 2017 were collected. The expressions of PD-1 and PD-L1 in 70 glioma tissues and 35 normal brain tissues were detected by immunohistochemical SP method. The relationship between the expressions of PD-1 and PD-L1 and their correlation with the clinicopathological features were analyzed. Results: The positive expression rates of PD-1 and PD-L1 in glioma tissues were 69% (48/70) and 62% (43/70), respectively, which were higher than those in normal brain tissues [29% (10/35), 31% (11/35)], the differences were statistically significant (χ² values were 15.099 and 8.407, both P < 0.05). The positive expression rates of PD-1 and PD-L 1 in high-grade glioma were 81% (30/37) and 73% (27/37), respectively, which were higher than those in low-grade glioma [55% (18/33) and 49% (16/33)], the differences were statistically significant (χ ² values were 5.699 and 4.415, both P < 0.05). There was no significant difference in the positive expression rates of PD-1 and PD-L1 among patients with different sex, age and maximum tumor diameter (all P > 0.05). There was a positive correlation between the expressions of PD-1 and PD-L1 proteins in glioma tissues (r= 0.372, P= 0.002). Conclusions The PD-1 and PD-L1 may become new biological indicators for evaluating the occurrence and development of glioma.

Objective To preliminarily proved that the cerebellar hypothalamic pathways regulate inflammatory cytokines involved in post?stroke depression(post?stroke depression,PSD). Methods 160 male(Sprague?Dawley,SD)rats were randomly divided into sham operation group,the stroke group,PSD group,kainic acid(kainic acid,KA)damage of cerebellar fastigial nucleus group,electrical damaged decussation of superior cer?ebellar peduncle(superior cerebellar peduncle,xSCP)group. The behavioral observation were observed and expression of IL?1βand TNF?αin hip?pocampus by immunohistochemistry. Results Compared with the sham operation group and stroke group,PSD group,TNF?α,IL?1βcontent signif?icantly increased;and the factor of rats with KA group and xSCP group expression consistent with PSD group,there was no significant difference among the three groups. Conclusion The cerebellar fastigial nuclear may through the cerebellar hypothalamic pathways regulate inflammatory cyto?kines and participate in post stroke depression.
