Acute lung injury （ALI） is one of the most common and critical diseases in clinical practice， with extremely high morbidity and mortality， seriously threatening human life and health. The pathogenesis of ALI is complex， in which the inflammatory response is a key factor. Studies have shown that NOD-like receptor protein 3 （NLRP3） inflammasomes are involved in ALI through mechanisms such as inflammation induction， increased microvascular permeability， recruitment of neutrophils， oxidative stress， and pyroptosis， playing a key role in the occurrence and progression of ALI. Therefore， regulating NLRP3 inflammasomes and inhibiting the release of inflammatory factors can alleviate the damage in ALI. At present， ALI is mainly treated by mechanical ventilation and oxygen therapy， which have problems such as high costs and poor prognosis. In recent years， studies have shown that traditional Chinese medicine （TCM） can reduce the inflammatory response and the occurrence of oxidative stress and pyroptosis by regulating the NLRP3 inflammasome， thus alleviating the damage and decreasing the mortality of ALI. Based on the relevant literature in recent years， this article reviews the research progress in TCM treatment of ALI by regulating NLRP3 inflammasomes， discusses how NLRP3 inflammasomes participate in ALI， and summarizes the active ingredients， extracts， and compound prescriptions of TCM that regulate NLRP3 inflammasomes， aiming to provide new ideas for the clinical treatment of ALI and the development of relevant drugs.

Referring to ZHANG Xichun's experience in treating dysentery from cold-fire accumulation， the treatment of ulcerative colitis （UC） in this paper can be divided into three stages including cold-fire accumulation stage， excessive heat and putrid intestine stage， and healthy qi deficiency and pathogen lingering stage. For people with slippery and excess pulse in the cold-fire accumulation stage， Xiaochengqi Decoction （小承气汤） added with Baishao （Radix Paeoniae Alba） and Gancao （Radix et Rhizoma Glycyrrhizae） can be used for purgation， while those with deficient pulse， Huazhi Decoction （化滞汤） or Xieli Decoction （燮理汤） can be used. In the excessive heat and putrid intestine stage， Tongbian Baitouweng Decoction （通变白头翁汤） and Jiedu Shenghua Elixir （解毒生化丹） are suggested. In the healthy qi deficiency and pathogen lingering stage， it is advised to use Jiedu Shenghua Elixir added with Shanyao （Rhizoma Dioscoreae）， and Sanbao Porridge （三宝粥）. Additionally， the medication rules， dosage and administration characteristics of Huanglian （Rhizoma Coptidis）-Rougui （Cortex Cinnamomi）， Yadanzi （Fructus Bruceae）， Diyu （Radix Sanguisorbae）， Shanyao and Liuhuang （Sulphur） by ZHANG Xichun have been summarized with the help of modern pharmacological research， so as to provide new ideas for the treatment of UC by TCM.

Objective:To evaluate the efficacy of neoadjuvant chemoimmunotherapy (NACI) combined with transoral robotic surgery (TORS) in the treatment of locally advanced oropharyngeal squamous cell carcinoma (OPSCC).Methods:This was a retrospective study of 15 patients with locally advanced OPSCC who underwent TORS after neoadjuvant therapy (NAT) at the Department of Otolaryngology-Head and Neck Surgery of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from April 2019 to February 2023. There were 12 males and 3 females, aged 31 to 74 years. Twelve cases were tonsil cancer, and 3 cases were tongue base cancer. There were 11 cases in stage Ⅲ and 4 cases in stage Ⅳ. Two patients received neoadjuvant chemotherapy and 13 patients received NACI, with 2 to 3 cycles, and all patients underwent TORS after multidisciplinary team consultation. The clinicopathological characteristics, surgical outcomes, and oncological results were summarized.Results:All surgeries were successfully completed with negative surgical margins, and no case was required conversion surgery. All patients were fed via nasogastric tubes postoperatively, with a median gastric tube stay of 7 days (range: 2-60 days). No tracheotomy was applied. There were no major complications such as postoperative bleeding. Pathological complete response (pCR) was found in 10 cases (76.9%) among the 13 patients with NACI. The follow-up time was 21 months (range: 10-47 months), and there was no death or distant metastasis. One patient with rT0N3M0 tonsil cancer had local recurrence 5 months after surgery. The 2-year overall survival and 2-year disease-free survival were respectively 100.0% and 93.3% in the 15 patients.Conclusion:NACI combined with TORS provides a safe, effective and minimally invasive treatment for patients with locally advanced oropharyngeal squamous cell carcinoma.

Objective:To investigate the preliminary efficacy of 3D printed individualized genioglossus advancement (GA) for the treatment of obstructive sleep apnea (OSA) in adults with micrognathia.Methods:The OSA patients with retropalatal and retroglossal collapses due to micrognathia underwent 3D printed individualized GA combined with Uvulopalatopharyngoplasty(UPPP) in Department of Otolaryngology, Head and Neck Surgery, Sun Yat-sen Memorial Hospital, Sun Yat-sen University. Clinical data including pre-and post-operative polysomnography (PSG), cephalometric measurements of genioglossus advancement, patient-reported symptom and surgical complications were collected. A comparison of pre-and post-operative data was conducted using paired t-tests. Results:Nineteen OSA patients with micrognathia successfully underwent 3D printed individualized GA combined with UPPP, and achieved an actual mean genioglossus advancement distance of (9.0±1.4) mm compared to the planned distance of (9.4±1.0) mm preoperatively ( t=0.81, P=0.427). Among the 14 patients followed up for more than 6 months, the mean AHI reduced by 60.4% at 6 months postoperatively, with 5 cases (5/14) cured and 5 cases (5/14) showing significant improvement, resulting in an overall surgical response rate of 10/14. All patients expressed satisfaction with their postoperative facial appearance, with 13 cases perceiving an improvement in attractiveness. Two patients reported temporary genial numbness, and one patient experienced temporary mandibular occlusal asthenia. Conclusion:The 3D printed individualized GA combined with UPPP effectively reduces AHI in adult OSA patients with micrognathia, accompanied by a low incidence of surgical complications and high patient satisfaction regarding postoperative facial appearance.

Objective:To explore any effect of standing balance dynamic lifting training on balance, motor functioning and the life quality of hemiplegic stroke survivors.Methods:Eighty stroke survivors were randomly divided into a control group and an experimental group, each of 40. Both groups received routine rehabilitation training, while the experimental group additionally underwent standing balance dynamic lifting training. Before the intervention, and 2 and 4 weeks later, everyone′s balance and motor functioning were evaluated using the Brunel balance assessment (BBA) and the timed " up and go" test (TUGT). Life quality was quantified using the stroke special quality of life scale (SS-QOL).Results:Significant improvement in the average walking function score, BBA total score and TUGT time was observed in both groups, with significantly greater improvement after 4 weeks than after two. The improvements in the experimental group were significantly greater than in the control group. After 4 weeks the average total SS-QOL score and the scores on all of its dimensions had increased significantly in the experimental group. The scores for energy, language, motor function, emotions, self-care ability, upper limb function and the average SS-QOL total score were all then significantly better in the experimental group.Conclusions:Standing balance dynamic lifting training can effectively improve the balance, motor function and life quality of stroke survivors with hemiplegia.

After the compatibility of Astragali Radix and Atractylodis Macrocephalae Rhizoma, most of the effective components of Astragali Radix increase, and the bioavailability is improved. Compared with the application of the two drugs alone, it can enhance the effects of immune regulation, anti-tumor, diuresis, lung protection, regulation of flora, and intestinal protection. However, the optimal compatibility ratio of Astragali Radix- Atractylodis Macrocephalae Rhizoma pair to exert various pharmacological effects still needs to be clarified. The drug pair and related preparations are mostly used in the treatment of nephropathy, but its mechanism of action needs to be further elucidated.

Heart failure is the leading cause of death worldwide. Compound Danshen Dripping Pill (CDDP) or CDDP combined with simvastatin has been widely used to treat patients with myocardial infarction and other cardiovascular diseases in China. However, the effect of CDDP on hypercholesterolemia/atherosclerosis-induced heart failure is unknown. We constructed a new model of heart failure induced by hypercholesterolemia/atherosclerosis in apolipoprotein E (ApoE) and LDL receptor (LDLR) dual deficient (ApoE^-/-LDLR^-/-) mice and investigated the effect of CDDP or CDDP plus a low dose of simvastatin on the heart failure. CDDP or CDDP plus a low dose of simvastatin inhibited heart injury by multiple actions including anti-myocardial dysfunction and anti-fibrosis. Mechanistically, both Wnt and lysine-specific demethylase 4A (KDM4A) pathways were significantly activated in mice with heart injury. Conversely, CDDP or CDDP plus a low dose of simvastatin inhibited Wnt pathway by markedly up-regulating expression of Wnt inhibitors. While the anti-inflammation and anti-oxidative stress by CDDP were achieved by inhibiting KDM4A expression and activity. In addition, CDDP attenuated simvastatin-induced myolysis in skeletal muscle. Taken together, our study suggests that CDDP or CDDP plus a low dose of simvastatin can be an effective therapy to reduce hypercholesterolemia/atherosclerosis-induced heart failure.

OBJECTIVE: To explore the effect of leucine-rich α-2-glycoprotein (LRG1) derived from hepatocytes on activation of hepatic M1 Kupffer cells. METHODS: A metabolic dysfunction-associated fatty liver disease (MAFLD) model was established in BALB/c mice by high-fat diet (HFD) feeding for 16 weeks. Oleic acid was used to induce steatosis in primary cultures of mouse hepatocytes. The mRNA and protein expressions of LRG1 in mouse liver tissues and hepatocytes were detected by real-time PCR and Western blotting. Primary hepatic macrophages were stimulated with the conditioned medium (CM) from steatotic hepatocyte along with LRG1 or transforming growth factor-β1 (TGF-β1), or both for 24 h, and the expression levels of inducible nitric oxide synthase (iNOS) was detected with Western botting, and the mRNA expressions of iNOS, chemokine ligand 1 (CXCL-1) and interleukin-1β (IL-1β) were measured by RT-PCR. The MAFLD mice were injected with LRG1 (n=6), TGF-β1 (n=6), or both (n=6) through the caudal vein, and the live tissues were collected for HE staining and immumohistochemical detection of F4/80 expression; the mRNA expressions of iNOS, CXCL-1 and IL-1β in liver tissues were detected using RT-PCR. RESULTS: The mRNA and protein expression levels of LRG1 were significantly downregulated in the liver tissues of MAFLD mice and steatotic hepatocytes (P < 0.05). Treatment of the hepatic macrophages with CM from steatosis hepatocytes significantly enhanced the mRNA expression levels of iNOS, CXCL-1 and IL-1β, and these changes were significantly inhibited by the combined treatment with TGF-β1 and LRG1 (P < 0.05). In MAFLD mice, injections with either LRG1 or TGF-β1 alone reduced hepatic lipid deposition and intrahepatic macrophage infiltration, and these effects were significantly enhanced by their combined treatment, which also more strongly inhibited the mRNA expression levels of iNOS, CXCL-1 and IL-1β (P < 0.05). CONCLUSION LRG1 inhibits hepatic macrophage infiltration by enhancing TGF-β1 signaling to alleviate fatty liver inflammation in MAFLD mice.
