Plants of the Isodon genus are an important source of terpenoids， with their constituents exhibiting rich structural diversity and remarkable biological activities （such as anticancer， antimicrobial， and anti-inflammatory properties）， demonstrating significant potential in the field of immunomodulation. This review summarizes recent advances in the immunomodulatory mechanisms， development and application of terpenoid compounds from the Isodon genus. It has been found that these compounds can modulate key inflammatory signaling pathways， such as nuclear factor-kappa B （NF-κB） and mitogen-activated protein kinases （MAPKs）， thereby blocking the cascade amplification of inflammatory factors， alleviating chronic inflammatory responses， and correcting immune dysregulation. Additionally， they can influence the polarization direction of macrophages and dynamically regulate the balance among different functional subsets of T cells， restoring immune homeostasis. Their clinical translation faces multiple challenges， including poor druggability， a lack of systematic safety data， the absence of precise pharmacodynamic biomarkers， complexities in clinical trial design， and unclear industrialization pathways.

Objective:To analyze the clinical application effects of different anesthesia maintenance methods in daytime pediatric sur-gery in oral maxillofacial surgery.Methods:80 children underwent anethesia for daytime surgery in oral maxillofacial region were en-rolled and divided into 2 groups(n=40).The maintenance dose of propofol was 2-3(mg·kg)/h in venous group,that was 3％to 4％sevofluranenas in opharyngeal airway-assisted inhalation group.The heart rate,mean arterial pressure,oxygen saturation,postoperative wake-up time and incidence of adverse reactions after the local anesthesia(T1),intraoperative(T2)and end-of-surgery(T3)were re-corded and compared between the 2 groups.Results:No statistical difference in heart rate change between the 2 groups at different time points(P＞0.05).The average arterial pressure decrease and the decrease of oxygen saturationin in the inhalation group were lower than those of the venous group(P＜0.01).The incidence of adverse events in the inhalation group were lower than that of the intravenous group(P＜0.05).Conclusion:Nasopharyngeal airway-assisted inhalation anesthesia has definite sedative effect in daytime pediatric pa-tients in oral maxillofacial surgery with less influence on the circulatory system and fewer adverse events.

Objective: To analyze the effects of different doses of flurbiprofen and other analgesic drugs on the postoperative analgesia in the Enhanced Recovery After Surgery (ERAS) . Methods: 98 patients with jaw cysts or multiple impact teeth were retrospectively analyzed. Patients were divided into 3 groups by the drug scheme: flurbiprofen 250 mg + 0. 9％ NS to 100 ml (group Ⅰ, n =32), sulfentanil 100 μg + azasetron 20 mg + 0. 9％ NS to 100 ml (group Ⅱ, n = 34), flurbiprofen 200 mg + sulfentanil 50 μg + azasetron 20 mg + 0. 9％ NS to 100 ml (group Ⅲ, n = 32) . Analgesic effects were evaluated at 3 h, 1 d and 2 d after surgery with Wong-Baker expression scale and numeric rating scale (NRS) . Questionnaire survey was also used to evaluate degree of satisfaction on analgesia. Results: Analgesia effective rate of group Ⅰ, Ⅱ and Ⅲ was 40. 62％, 67. 65％ and 68. 75％ respectively (P ＜0. 05) . Degree of satisfaction on analgesia of group Ⅰ, Ⅱ and Ⅲ was 71. 87％, 58. 82％ and 93. 75％ respectively (P ＜ 0. 05) .Conclusion: Flurbiprofen combined with sulfentanil has good analgesic effects and low side effects in the maxillofacial surgery of jaw cysts and multiple impact teeth.

Objective:To investigate the prevalence,and the factors that influence depressive symptoms among chronic respiratory disease patients in tertiary hospital.Methods:A total of 1713 outpatients and inpatients with chronic respiratory disease were selected from 8 tertiary hospitals in Jiangsu Province from July to September,2014 and screened according to the Hospital Anxiety Depression Scale-D (HADS-D).A questionnaire developed by this research group,was used to collect demographic and clinical information.Logistic regression was used to identify factors that were associated with depressive symptoms.Results:The overall rate of depressive symptoms was 46.0％.Multiple logistic analysis showed that spinsterhood (OR ＝ 0.45),higher education level (middle school /high school/technical school OR ＝0.65;college degree or aboveOR ＝0.28),BMI ≥24 (OR ＝0.71) were associated with decreased risk of depressive symptoms (P ＜ 0.05).B MI ＜ 18.5 (OR ＝ 1.52,),average income of family ≥10000 RMB (OR ＝ 1.37-1.96),limited daily activities (OR ＝ 1.72),poorer sleep quality (OR ＝ 1.45),and negative life events (OR ＝ 1.62) were associated with increased risk of depressive symptoms (P ＜ 0.05).Conclusion:The prevalence of depressive symptoms among chronic respiratory disease patients in tertiary hospitals in Jiangsu Province was higher.Marital status,education level,income,BMI,limited daily activities,subjective sleep quality,negative life events may be the related factors of depressive symptoms of chronic respiratory diseases patients.

Objective To investigate the effect of liraglutide on the expression of NF-kappa B (NF-κB), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in renal tissue of insulin resistance rats. Method The rats were divided into 4 groups, control group ,high fat group ,liraglutide low dose group [100 μg/(kg· d)], liraglutide high dose group[100 μg/(kg·d)]. Detection of serum creatinine and urea nitrogen by automatic biochemical analyzer, and 24 h urine micro albumin was determined by immunoassay. The protein concentration of serum NF-κB,TNF-α and IL-6 was measured by ELISA. The expression of NF-κB,TNF-α and IL-6 mRNA in renal tissues was determined by RT-PCR. Results Compared with the control group, the serum creatinine, blood urea nitrogen,urinary protein, and the expression of NF-κB, TNF-α and IL-6 were significantly higher in high fat group, respectively (P < 0.05). The glomerular basement membrance thickening and foot process fusion were seen under electron microscope. Liraglutide high dose intervention can significantly reduce these changes. Conclusions Liraglutide can inhibit the expression of NF-κB,TNF-α and IL-6 in renal tissues of high fat induced insulin resistance rats,in a concentration dependent manner, which possibly improve renal function.

Objective:To establish an animal model of bone distraction in the irradiated dog mandible.Methods:1 0 Chinese dogs were used.8 dogs received a unilateral irradiation of 60 Co(Group R)in the mandible with a total dose of 22.8 Gy in four 5.7 Gy frac-tions (biologically equivalent to 50 Gy/25 fractions).The other 2 dogs without irradiation served as the controls(Group C).Bilateral corticotomy was made 3 months after completion of irradiation.After a 1 -week latency period,bone distraction was activated at a rate of 0.5 mm twice daily for 1 0 days,followed by a consolidation phase of 8 weeks.New bone was evaluated by radiographic,histological and single photon emission computed tomography(SPECT)analysis.Results:One dog was excluded from the study due to anaesthetic death in group R.After 8 weeks of consolidation,no difference was found between the percent area of new bone of both groups.New bone was more mature and organized in Group C than that in Group R.SPECT analyses showed that there was active osteogenic activity in Group R.Conclusion:Distraction osteogenesis can be achieved in the irradiated dog mandible.

?Objective: To examine the morphologic changes produced by extranueral injection of methylene blue around rat infraorbital nerve. Methods: Under direct vision, 50 ?l of methylene blue at the concentration of 20 g/L was injected extranuerally into the infraorbital foramen on one side of the maxillar bone of each of 32 rats; physiological saline was used as the control on the contralateral side of each animal. Animals were killed at 3 days, 2, 4, 8 and 14 weeks after the application of methylene blue respectively. The infraorbital nerve specimens were examined by light and electron microscopes. Results:Axolysis and demyelination were found in the outer zone of the nerve bundles, and a few of centrally located axons were damaged in 2 and 3 weeks. 4 weeks later,a few of regenerated fibers were observed. Wallerian degeneration still remained and more regenerated fibers were found in 14 weeks. The sheath of myelinated fibers became twisted, thick and dissolved. The axonal changes characterized by either swelling, shrinking or vacuolization of axoplasm. Lysosome could be seen in the axons. The changes of myelinated fibers were more evident than that of demyelinated fibers. At the later stage, the regularly regenerated fibers with thin sheath could be seen. No change was observed in the Schwann cells. Conclusion: 20 g/L methylene blue can result in the changes of the sheath and axons of nerve fibers
