The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

In addition to the essential pharmacologi-cal effects of opioids,situational cues associated with drug addiction memory are key triggers for drug seeking.CircRNAs,an emerging hotspot regulator in crown genet-ics-play an important role in central nervous system-relat-ed diseases.However,the internal mediating mechanism of circRNA in the field of drug reward and addiction mem-ory remains unknown.Here,we trained mice on a condi-tional place preference(CPP)model and collected nucle-us accumbens(NAc)tissues from day 1(T0)and day 8(T1)for high-throughput RNA sequencing.qRT-PCR revealed that circTmeff-1 was highly expressed in the NAc core but not in the NAc shell,suggesting that it plays a role in addiction memory formation.Meanwhile,the reverse regulation of circTmeff-1 by adeno-associated viruses could both inhibit the formation of addiction mem-ory in the NAc core or shell.Subsequently,the GO and KEGG analyses indicated 21 that circTmeff-1 might regu-late the addiction memory via the MAPK and AMPK path-ways.These findings suggest that circTmeff-1 in NAc plays a crucial role in morphine-dependent memory for-mation.

OBJECTIVES: Pelvic floor dysfunction (PFD) seriously affects women's physical and mental health. Pregnancy and childbirth are recognized as high-risk factors for PFD, and studies have shown that vaginal microenvironmental disorders can promote the development of pelvic organ prolapse. In this study, we intend to investigate whether the changes in vaginal microecology during pregnancy affect the pelvic floor function and participate in the development of postpartum PFD, and provide a basis for the prevention and treatment of PFD. METHODS: A total of 358 full-term mothers who delivered in Third Xiangya Hospital, Central South University from November 2019 to April 2020 were selected and underwent review 6 to 8 weeks after delivery. The pelvic floor structures were examined using pelvic floor ultrasound, and ultrasound values were measured at rest and at maximum Valsalva maneuver. One hundred and seventy women with PFD were assigned in a PFD group, and 188 women without PFD were assigned in a control group. The clinical data of all mothers were collected, and the clinical data and the results of microecological testing for vaginal secretions after 36 weeks of gestation and before delivery were compared between the 2 groups. The correlation of PFD with leucorrhoea cleanliness, lactobacillus level, bacterial vaginosis (BV), and vulvovaginal candidiasis (VVC) was analyzed, and logistic regression analysis was used to screen for independent risk factors for PFD. RESULTS: The incidences of VVC, BV, Lactobacillus vaginalis deficiency, and leucorrhoea cleanliness ≥III° were all higher in the PFD group than those in the control group (P<0.05). Among them, leukocyte cleanliness ≥III°and lack of Lactobacilli in the vagina were independent risk factors for the development of PFD, while VVC and BV were not independent risk factors for the development of PFD. CONCLUSIONS Postpartum PFD is related to vaginal microecological imbalance in late pregnancy, among which Lactobacillus vaginalis deficiency and leucorrhoea cleanliness ≥III° are independent risk factors for the occurrence of PFD. Therefore, pregnant women with Lactobacillus vaginalis deficiency and leucorrhoea cleanliness ≥III° in late pregnancy should pay attention to the occurrence of postpartum PFD, and early diagnosis and effective intervention of postpartum PFD should be enhanced.
