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.

OBJECTIVE To evaluate the quality of guidelines/consensus on therapeutic drug monitoring （TDM） of anti-tumor necrosis factor-α （TNF-α） in patients with inflammatory bowel disease （IBD） in China and globally. METHODS PubMed， Embase， CNKI， Wanfang data， VIP， and release websites of guidelines/consensus in China and globally were searched to collect guidelines/expert consensus on TDM with anti-TNF-α for IBD patients. The search period was from database establishment to June 2023. After two investigators independently screened the literature and extracted the data， the methodological quality of the included guidelines/consensuses was evaluated using the Appraisal of Guidelines for Research and Evaluation Ⅱ. The main recommendations of the included guidelines/consensuses were summarized. RESULTS A total of 9 articles were included， 3 were guidelines and 6 were expert consensus. The standardized percentages of the 9 guidelines/consensus in the 6 dimensions （scope and aims， participants， rigor of formulation， clarity of expression， application， and editorial independence） were 90.43%， 41.98%， 52.55%， 85.49%， 19.00%， and 76.85%， respectively. Eight guidelines/consensus had a recommendation of grade B and one consensus of grade C. The main recommendations involve TDM application scenarios， threshold ranges， strategy adjustments， detection methods， and interpretation of results. Most guidelines/consensus recommend passive TDM for non-responders. It is recommended to set the TDM concentration range according to the expected treatment results and make strategy adjustments in combination with the disease condition and TDM results. Additionally， the same test method is recommended for the same patient. Some guidelines/consensus hold that no differences were noted in the interpretation of results between biosimilar and original drug. CONCLUSIONS The overall quality of the included guidelines/consensus was fair， with relatively consistent recommendation. Clinicians need to understand the characteristics and limitations of TDM with this class of drugs， and interpret and apply results of TDM in combination with specific clinical treatment goals.

BACKGROUND: Following trauma caused by seawater, cells often exhibit special pathological changes because of the special physico-chemical properties of seawater.OBJECTIVE: To observe corneal histopathological changes and interleukin-6 level in aqueous humor of a rabbit model of penetrating corneal trauma combined with seawater immersion.METHODS: The rabbit eye models of penetrating corneal trauma caused by firecrackers were established in 16 adult healthy grey rabbits. A 3-mm whole-layer incision was made in the cornea. The right eyes served as experimental sides and the left eyes served as controls. Seawater was injected into the aqueous humor of the right eyes via the corneal incision. The eye surface was flushed with seawater for 30 minutes. Physiological saline was used for the left eyes. RESULTS AND CONCLUSION: Optical microscopy results showed that at 1, 2, 3 days after model establishment, corneal cells on the experimental side exhibited severe necrosis and abscission, obvious swelling of substantia propria layer complicated by cellular infiltration. At 1 and 2 days after model establishment, the pathological changes on the control side were the same as the experimental side, but they were mild, but at 3 and 5 days, they were obviously alleviated. At 1, 2, 3 days after model establishment, interleukin-6 level in aqueous humor was significantly higher on the experimental side than on the control side (P < 0.05). These findings suggest that the degree of injury on the experimental side was more severe than that on the control side, indicating that seawater may be an important causative factor of corneal injury.

Background Researches have demonstrated that ocular hypertension induces the ischemia-reperfusion of retina and further leads to the degeneration of retinal ganglion cells,but its mechanism is beyond understanding.Objective The present study aims to observe the effects of static pressure on the morphology,proliferation activity and viability of cultured retinal microvascular endothelial cells (RMECs) and evaluate the expression of ET-1 and NO in these cells under variant static pressure.Methods RMECs were isolated from 30 healthy Wistar rats and cultured using explant culture method by Ⅷ factor antibody and PECAM-1 antibody.The static pressure of 1.33kPa,2.67kPa,5.33kPa and 10.67kPa was used in culture bottle respectively.The RMECs without static pressure were used as normal control group.The morphology of RMECs under the different static pressure was observed by inverted phase contrast microscopy,and the number of RMECs was counted using the counting plate.Cellular viability was studied by trypan blue staining.The changes of ET-1 and NO_2~-/NO_3~-,two metabolic products of NO,in the medium were detected by radioimmunoassay and Griess's nitrate reductase method.The expression of ET-1,eNOS and iNOS mRNA in RMECs was analyzed by semi-quantitative RT-PCR 24 hours after treatment of variant static pressure.Results Cultured RMECs sticked well at 24 hours and reached to confluence at 48 hours and showed the red fluorescence for Ⅷ factor antibody and PECAM-1 antibody.Enlargement of nuclei,extenders of cell bodies and suspension of RMECs in medium were observed.The number of RMECs was gradually increased.The cell viability was reduced with the raise of static pressure among these four groups(F=12.205,P＜0.01;F=11.180,P＜0.01).The static pressure increased the content of ET-1 released by RMECs in 2.67kPa,5.33kPa and 10.67kPa of static pressure groups,and concentrations of NO_2~-/NO_3~- in the medium showed a significant increase in 5.33kPa and 10.67kPa of static pressure groups compared with normal and 1.33kPa of static pressure groups(P＜0.01).The expressions of ET-1 mRNA,eNOS mRNA and iNOS mRNA were considerably enhanced in 5.33kPa and 10.67kPa of static pressure groups compared with normal control group(P＜0.01).Conclusion Raised static pressure causes the alteration of RMGCs structure and morphology.Static pressure could upregulate the expressions of ET-1,eNOS and iNOS mRNA in RMECs and increase the release of ET-1 and NO.This pathway might be one of pathologic mechanisms of retinal injury induced by high intraocular pressure.
