Type 2 inflammation（T2 inflammation）is an immune response mediated by Th2 cells，eosinophils，type 2 innate lymphocytes，and other cells. Its pathological characteristics are manifested by the abnormally high expression of type 2 cytokines such as IL-4，IL-5，and IL-13，and it widely involves allergic diseases including asthma，allergic rhinitis，and atopic dermatitis. Ginsenosides are the core active ingredients of ginseng and the key substances for ginseng to exert its pharmacological effects. It has anti-inflammatory and immunomodulatory effects. This article reviews the mechanism of action，experimental research progress，and clinical application prospects of ginsenosides in T2 inflammation，explores the therapeutic potential and clinical challenges of ginsenosides，and proposes future research directions.

Objective:Medial sural artery perforator flap (MSAPF) was applied to aesthetically reconstruct wounds in foot, and clinical outcome of this surgical method was explored.Methods:A retrospective analysis was conducted on the data of 10 patients who underwent the surgery of transfer of free MSAPF in reconstruction of foot wounds in the Department of Foot and Ankle Surgery, Xuzhou Renci Hospital from January 2020 to January 2023. The patients were 6 males and 4 females, aged 21 to 52 years, with an average of 42.5 years. The soft tissue defects of the injuries were at 2.0 cm × 4.0 cm to 3.5 cm × 6.0 cm in size, with deep tissues exposure down to the base of wound. MSAPF was used for aesthetic reconstruction of the wounds. The surgical procedures were: (1) The flap was thinned under a microscope and only the subdermal vascular network was kept. (2) Vascular pedicle of the flap was taken as long as possible and had it anastomosed with the proximal dorsal foot artery and vein through a subcutaneous tunnel. (3) Allg?wer-Donati method was applied to suture the skin of flap. (4) Donor site was directly closed in surgery. All patients were entered in the scheduled postoperative follow-up at the outpatient clinic of the surgeon who performed the surgery to evaluate the postoperative effect and observe the survival of flaps. Maryland foot function score and British Medical Research Council (BMRC) sensory function score were used to assess the recovery of flap and limb function.Results:The flaps completely survived, and all the donor and recipient sites had primary healing. All of the 10 patients were included in the postoperative follow-up which lasted 8 to 15 months, with an average of 12 months. The flaps from foot featured a pleasing appearance, with good elasticity and wear-resistant. All patients were satisfied and able to walk normally and bear weight without an occurrence of flap ulceration. At the final follow-up, the therapeutic effect was evaluated according to the Maryland scoring system and achieved the scores at 91 to 98, with 95.6 in average. Nine patients were rated as excellent and 1 as good. The sensory grading by BMRC for the flaps was as follows: the flap sensation of the sutured nerve group recovered to S 3 in 3 cases and S 4 in 2 cases, while the non sutured nerve group only recovered protective sensation, S 2 in 3 cases and S 2+ in 2 cases. Conclusion:By applying MSAPF aesthetics to treat foot wounds, a good appearance has been achieved, with good functional recovery and satisfactory therapeutic effects.

Peptides that are composed of dextrorotary (d)-amino acids have gained increasing attention as a potential therapeutic class. However, our understanding of the in vivo fate of d-peptides is limited. This highlights the need for whole-body, quantitative tracking of d-peptides to better understand how they interact with the living body. Here, we used mouse models to track the movement of a programmed death-ligand 1 (PD-L1)-targeting d-dodecapeptide antagonist (DPA) using positron emission tomography (PET). More specifically, we profiled the metabolic routes of [⁶⁴Cu]DPA and investigated the tumor engagement of [⁶⁴Cu/⁶⁸Ga]DPA in mouse models. Our results revealed that intact [⁶⁴Cu/⁶⁸Ga]DPA was primarily eliminated by the kidneys and had a notable accumulation in tumors. Moreover, a single dose of [⁶⁴Cu]DPA effectively delayed tumor growth and improved the survival of mice. Collectively, these results not only deepen our knowledge of the in vivo fate of d-peptides, but also underscore the utility of d-peptides as radiopharmaceuticals.

Objective To explore the feasibility and efficiency of the treatment of lumbar degenerative diseases after transforaminal lumbar interbody fusion(TLIF)and posterolateral fusion(PLF)procedures in which unilateral pedicle screw fixation was used.Methods From December 2006 to August 2008,78 cases with the lumbar degenerative diseases who received lumbar posterolateral fusion were analyzed.There were 48 cases of which underwent TLIF and PLF procedures with unilateral pedicle screw fixation(unilateral group),including 25 males and 23 females with an average of 47.6 years;and 30 cases of which underwent TLIF and PLF procedures with bilateral pedicle screw fixation(bilateral group),including 21 males and 9 females with an average of 50.5 years.The clinical effects between the two groups were evaluated with Oswestry disability index and visual analogue score(VAS)index.The operation time,blood loss,fusion rates and intervertebral collapse rates were also compared.Results Oswestry disability index,low back pain VAS index and skelalgia VAS index in both groups showed statistical significance between preoperation and 3 months,or 3 months and 1 year postoperatively.There was no difference in score improvement between the two groups.There were difference in operation time,blood loss and cost of hospitalization between unilateral and bilateral group.The former was lower.There was no difference in postoperative length of stay between the two groups.The fusion rate of unilateral group and bilateral group were 91.7%(44/48)and 93.3%(28/30),respectively.Conclusion Auto graft combined with unilateral pedicle screw fixation provids better spinal instant stability.TLIF and PLF with unilateral pedicle screw fixation was a satisfactory method in treating degenerative disease of lumbar vertebrae.

In the experimental study on the electrophysiology and functions of heart in the animal, the thorax should be opened to expose the heart, at the same time natural breathing is maintained instead of artificial breathing. The key procedure of this new method is to avoid injuring the pleural cavity, so pneumothorax can be prevented. By means of this new method some subject studies have been finished.
