Objective To explore the characteristics of the inhibitory effect of Evodiamine on the proliferation of activated T cells. Methods Mononuclear cells from peripheral blood (PBMCs) were obtained from healthy donors through density gradient centrifugation, and T cells were subsequently purified by using immunomagnetic bead separation. T cell activation was induced by employing anti-human CD3 and anti-human CD28 antibodies. T cells were treated with different concentrations of EVO (0.37, 1.11, 3.33, and 10)μmol/L. Flow cytometry was applied to evaluate the proliferation index, apoptosis rate, viability, CD25 expression levels, and cell cycle distribution of T cells. The expression levels of cytokines IL-2, IL-17A, IL-4, and IL-10 were quantified by using ELISA. Results 1.11, 3.33 and 10 μmol/L EVO effectively inhibited the proliferation of activated T cells, with an IC₅₀ of (1.5±0.3)μmol/L. EVO did not induce apoptosis in activated T cells and affect the survival rate of resting T cells. EVO did not affect the expression of CD25 and the secretion of IL-2 in activated T cells. EVO arrested the T cell cycle at the G2/M phase, resulting in an increase in G2/M phase cells, and exhibited a concentration-dependent effect. EVO did not affect the secretion of IL-4, IL-10 by activated T cells, but significantly inhibited the secretion of IL-17A. Conclusion EVO did not significantly affect the activation process of T cells but inhibited T cell proliferation by arresting the cell cycle at the G2/M phase and significantly suppressed the secretion of the pro-inflammatory cytokine IL-17A, which suggests that EVO has the potential to serve as a lead compound for the development of low-toxicity and high-efficiency immunosuppressants and elucidates the mechanisms underlying the anti-inflammatory and immunomodulatory effects of the traditional Chinese medicine Evodia rutaecarpa.

Objective:To observe the safety of 2-port non-vitrectomized subretinal injection (SRI) for the treatment of Bietti crystalline dystrophy (BCD).Methods:A exploratory clinical study. From February to May 2023, 6 BCD patients with 6 eyes who were confirmed by examination in Xiamen Eye Center of Xiamen University and were treated with SRI adeno-associated virus vector transgenic drugs were included in the study. Among them, 2 males had 2 eyes and 4 females had 4 eyes. Age were 34-60 years old. The study eye underwent adeno associated virus gene therapy via 2-port non-vitrectomized SRI. Two scleral ports were created using 25G vitrectomy trocar to place the light pipe and injection cannula. Anterior chamber paracentesis was performed to lower intraocular pressure. Under the silicone oil infusion mode of the vitrectomy machine, a 38G injection cannula penetrated the retina to reach the subretinal space. The injection speed was controlled by the foot pedal of the vitrectomy machine, and the drug was slowly injected into the subretinal space to create a subretinal bleb. if intra-ocular pressure assessed by finger palpation was high at the end of injection, drainage of the aqueous humor can be made by compressing the cornea incision until the intraocular pressure was normal. Patients were followed for 9-12 months and be examined using the same equipment and methods as before.Results:Retinal pigment epithelium and choroidal atrophy were observed in all 6 eyes of 6 patients were graded as stage Ⅲ by the fundus examination revealing atrophy of retinal pigmented epithelium and choroid, with or without yellow- white crystals and/or complex lipid. The range were operation time 9-14 minutes. No vitreous prolapse, retinal hemorrhage, or retinal tear was observed during surgery. After 24 hours, optical coherence tomogrophy examination showed absorption of subretinal fluid and retinal reattachment. None of the six patients showed corneal keratic precipitates, anterior chamber cells, vitreous cells, inflammation, high intraocular pressure, or retinal tear within the 9-month follow-up.Conclusion:Subretinal injection without vitrectomy using two ports is a safe and feasible alternative for adult gene therapy, and it shortens the surgical time.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Autophagy， a mechanism of cell self-protection and self-renewal， is associated with the occurrence and development of lung cancer. Favorable autophagy can slow down the progression of lung cancer， while unfavorable autophagy can promote the progression. Therefore， regulating the level of autophagy is of great significance in the treatment of lung cancer. Healthy Qi deficiency and pathogenic Qi stagnation is an extension of the theory of deficiency and Qi stagnation proposed by the Academician WANG Yongyan. It refers to the pathological process that the abnormal body fluid metabolism caused by Qi deficiency of lung， spleen， and kidney results in phlegm and blood stasis. Lung cancer has the root cause of Qi deficiency of lung， spleen， and kidney and the syndrome of phlegm and blood stasis. The autophagy in lung cancer is interconnected with healthy Qi deficiency and pathogenic Qi stagnation. The Qi deficiency of lung， spleen， and kidney is the key factor for the weakening of favorable autophagy in lung cancer， which inhibits the apoptosis of tumor cells and leads to the accumulation of harmful substances. Phlegm and blood stasis is a direct factor enhancing the unfavorable autophagy in lung cancer， which promotes the autophagic death of normal cells， weakens the immunosuppressive effect of immune cells on tumor cells， and leads to the proliferation and migration of tumor cells. The combination of healthy Qi deficiency and pathogenic Qi stagnation results in the development of autophagy in an unfavorable direction and finally leads to the continuous progression of lung cancer. Therefore， the traditional Chinese medicine （TCM） treatment of lung cancer should follow the principle of reinforcing healthy Qi and expelling pathogenic Qi， removing phlegm and resolving stasis， so as to enhance favorable autophagy while inhibiting unfavorable autophagy. Such therapy can inhibit the proliferation and migration of tumor cells and promote the remission of lung cancer. According to the existing literature， Chinese medicine monomers are mainly used to treat lung cancer by regulating autophagy. The Chinese medicine intervention of autophagy in lung cancer mainly aims to promote the activation of autophagy. This may be because the favorable autophagy weakening caused by the Qi deficiency of lung， spleen， and kidney is the fundamental reason for the development of lung cancer.

Bipolar disorder （BD） is considered to be mainly related to qi， phlegm， fire and deficiency. Binding constraint of liver qi is the initial cause， while phlegm and qi interact obstruction as well as phlegm and fire interact binding is the key pathogenesis of the transformation between depression and mania， and deficiency of both qi and yin is the main reason of the protracted course of disease. In clinical practice， BD is divided into binding constraint of liver qi pattern， phlegm and qi interact obstruction pattern， phlegm and fire interact binding pattern， and deficiency of both qi and yin pattern， which can be treated with Jinyu Shugan Powder （金玉疏肝散）， Kaiyu Wendan Decoction （开郁温胆汤）， Qingxin Huatan Decoction （清心化痰汤）， and Baihe Shengmai Beverage （百合生脉饮） in their modifications respectively； moreover， Guanye Jinsitao （Herba Hyperici Perforati） is usually used to rectify qi， relieve phlegm and clear heat. It is also suggested to put focus on the prevention and treatment of qi， phlegm and heat simultaneously， and modify the medicinals flexibly in accordance with the pathogenesis evolution and the abnormal exuberance.

In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

Objective: To evaluate the clinical effects of vitrectomy with or without fovea-sparing internal limiting membrane peeling on macular foveoschisis (MF) secondary to pathologic myopia. Methods: A non-randomized controlled study was adopted.Twenty-three patients (25 eyes) with refractive error ≥-8.00 DS and MF either combined with foveal retinal detachment or epi-macualr membrane or lamellar macular hole.The subjects were divided into non-internal limiting membrane peeling group (11 patients /11 eyes) who underwent triamcinolone (TA) assisted vitrectomy and fovea-sparing internal limiting membrane peeling group (12 patients/14 eyes) who underwent TA assisted vitrectomy with fovea-sparing internal limiting membrane peeling.The baseline data such as age, best corrected visual acuity (BCVA), refractive error, axial length were not significant difference between the two group.Main outcomes were BCVA, remission of MF defined by optical coherence tomographyc OCT as well as complications.This study followed the Declaration of Helsinki and this protocol was approved by Ethic Committee of Xiamen Eye Center of Xiamen University (NO.XMYKZX-2016-YWS-007). Results: All patients completed follow-up for more 6 months.BCVA (LogMAR) was 0.47±0.30 in non-internal limiting membrane peeling group and 0.40±0.33 in fovea-sparing internal limiting membrane peeling group, showing no significant difference between the two groups (t=0.66, P=0.52). Complete remission of MF was achieved in 22 eyes.The remission time in non-internal limiting membrane peeling group was 2.5 (1.8, 9.3) months, and 1.0 (1.0, 3.8) months in fovea-sparing internal limiting membrane peeling group, no statistical significance was obtained between the two groups (U=35.00, P=0.09). One eye had post-operative macular hole in non-internal limiting membrane peeling group, accounting for 9%, while in fovea-sparing internal limiting membrane peeling group, one eye had macular hole, accounting for 7%, and one eye had rhegmatogenous retinal detachment post-operatively, accounting for 7%. Conclusions MF can be resolved by vitrectomy while complete remission can achieved more quickly when combined with fovea-sparing internal limiting membrane peeling.

OBJECTIVE: To explore the influence of negative emotion on the professional identity of nurses in Guangdong Province and the moderating role of social support during COVID-19 pandemic. METHODS: A convenience sampling method was used to select 436 nurses in Guangdong Province as study subjects. The Depression-Anxiety-Stress Scale, Nurse Professional Identity Scale and Perceived Social Support Scale were used to investigate the negative emotion, professional identity and social support of these nurses. RESULTS: The median, the 25 th and 75 th percentile scores of the negative emotion total scores of nurses was 10.0(3.0,17.8). The total scores of professional identity and social support were(106.6±16.9) and(56.9±13.2), respectively. The professional identity and social support were negatively correlated with negative emotion(P<0.01), while the professional identity was positively correlated with social support in these nurses(P<0.01). The negative emotion of nurses can negatively predict their professional identity, and social support plays a moderating role in it.CONCLUSION: The higher the degree of social support, the less negative emotional impact on professional identity of nurses during COVID-19 pandemic. Nurses should be given more social supports.

Objective: To observe the clinical efficacy of digital 3D heads-up display viewing system(3D viewing system) and intraoperative OCT (iOCT) in vitrectomy for myopic foveoschisis (MF). Methods: A retrospective, consecutive case series. From October 2018 to May 2019, Nineteen eyes of 19 consecutive patients with MF diagnosed in Xiamen Eye Center of Xiamen University who underwent vitrectomy were included in this study. There were 7 males and 12 females, with the mean age of 54.47±11.38 years. The average axial length was 30.40±2.30 mm, the mean logMAR BCVA was 0.56±0.31, the mean central foveal thickness (CFT) was 317.80±151.9.32 μm, the mean max retinal thickness (maxRT) was 556.7±143.7 μm. All the surgeries performed combined with 3D viewing system with iOCT. The standard 25G pars planar vitrectomy were performed with removing the posterior vitreous and indocyanine green (ICG) staining of internal limiting membrane (ILM) and air-fluid exchange. Thirteen of 19 eyes underwent fovea-sparing ILM peeling and the other 6 eyes not. The average follow-up was 4.2±1.4 months. All the patients were on regular follow-up to document the changes on BCVA, anatomical changes in macula, CFT and maxRT. Paired t test was used to compare BCVA, CFT and maxRT before and after surgery. Results: The fine images of macula were clearly shown on the 3D viewing system in all eyes. The electronic green filter enhanced the contrast sensitivity of ICG stained images. Clear images of macula were captured by iOCT in all eyes. The average surgical time was 35.5±8.2 min. On the last follow-up, 16 of 19 eyes with MF resolved. The mean CFT was 178.5±103.5 μm, the maxRT was 341.8±83.8.16 μm, and the mean logMAR BCVA was 0.35±0.22. The differences of CFT, maxRT and logMAR BCVA before and after surgery were statistically significant (t=4.181, 7.154, 5.129; P<0.001). Minimal invisible full thickness macular hole were detected in 2 eyes by iOCT and repaired with auto serum or ILM flap covering. There was no complication associated with the 3D viewing system. Conclusions 3D viewing system provides improved contrast and crystal clear macular image stain with ICG in pathological myopia. iOCT can detect the minimal invisible full thickness macular hole during surgery. Both may contribute to improved MF closure rate and BCVA.
