Based on the traditional Chinese medicine theory that "all pain， itching， and sores are related to the heart"， this paper proposes treating recurrent aphthous ulcers from the perspective of the heart. It suggests that excessive heart fire and tissue erosion due to flaming fire in the heart meridian constitute the core pathogenesis of this condition. Hyperactive heart fire is identified as the key pathogenic factor， while heart yin deficiency， obstruction of the heart collaterals， and malnourishment of the heart spirit are considered significant contributing factors. Clinically， the treatment follows the principle of clearing heart fire as the main strategy， supplemented by nourishing yin， activating collaterals， and calming the spirit. The self-formulated Qingxin Yuchuang Formulation （清心愈疮方） serves as the base prescription， with flexible modifications incorporating the Yuyin Formulation （育阴方）， Huoxue Formulation （活血方）， and Yu'an Formulation （郁安方） to address specific syndromes involving heart yin deficiency， collateral blockage， and emotional disturbance.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

AIM:To rapidly evaluate the effective-ness,safety and economy of dienogest in the treat-ment of endometriosis so as to provide evidence-based reference for clinical drug selection and deci-sion.METHODS:Retrieved from PubMed,Embase,Cochrane Library,CNKI,SinoMed,Wanfang and health technology assessment(HTA)organization websites,HTA report,systematic review/Meta-anal-ysis and pharmacoeconomic study were included during the inception to Sep 2023.Data extraction and quality evaluation were carried out for the lit-erature that met the inclusion and exclusion crite-ria,and the research results were summarized and analyzed qualitatively.RESULTS:Nine systematic re-view/Meta-analyses,and 2 pharmacoeconomic studies were included.The quality of Meta-analysis literatures was low,and the quality of economic re-search was good.In terms of effectiveness,com-pared with no treatment,dienogest can significant-ly reduce postoperative recurrence rate,VAS score,and improve pregnancy rate and effective rate;Di-enogest has similar therapeutic effects in terms of recurrence rate as GnRHa and COC;With regard to recurrence rate and pregnancy rate,dienogest is superior to danazol,gestrinone,and mifepristone.In terms of safety,compared with placebo,the inci-dence of vaginal bleeding and headache was signifi-cantly increased with dienogest,and there was no difference in bone loss;The incidence of vaginal bleeding caused by dienogest was significantly high-er than that of GnRHa,but the incidence of hot flashes and bone loss was lower.In terms of econo-my,dienogest has a more cost-effective advantage comparing with GnRHa,but does not have econom-ic benefits comparing with COC.CONCLUSION:Di-enogest has good effectiveness and safety in the treatment of endometriosis,and economically su-perior to GnRHa,but inferior to COC.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective:To investigate the association between sleep status and the risk for coronary heart disease in adults in Suzhou.Methods:Using the baseline and follow up information of 53 269 local residents aged 30-79 years in China Kadoorie Biobank conducted in Wuzhong District, Suzhou, 51 929 subjects were included in this study after excluding those reporting coronary heart disease, stroke and cancer at the baseline survey. A Cox proportional hazards regression model was used to analyze the association of healthy sleep score (0-3 points) and sleep factors (snoring, insomnia, long sleep duration and nap) with the risk for coronary heart disease.Results:The median follow-up time was 11.12 years, and 1 304 individuals were diagnosed with coronary heart disease during the follow-up. After adjusting for potential confounders, occasional snoring ( HR=1.20, 95% CI: 1.04-1.38), usual snoring ( HR=1.17, 95% CI: 1.02-1.33), insomnia disorder ( HR=1.41, 95% CI: 1.12-1.78), daytime dysfunction ( HR=1.56, 95% CI: 1.20-2.03) and perennial nap ( HR=1.37, 95% CI: 1.19-1.59) were associated with increased risk of coronary heart disease. Compared with those with sleep score of 0 - 1 (low sleep quality), the people with sleep score of 3 had reduced risk of coronary heart disease by 26% ( HR=0.74, 95% CI: 0.63-0.87). Stratified analysis showed that the association of healthy sleep score 3 with risk of coronary heart disease was stronger in low physically active individuals (interaction P<0.05). Conclusions:Snoring, insomnia disorders, daytime dysfunction, and perennial napping were all associated with increased risk for coronary heart disease, and keep healthy sleep mode might reduce the risk for coronary heart disease in adults.

ObjectiveTo explore the mechanism of Huanglian Jiedutang in inhibiting the pyroptosis mediated by NOD-like receptor protein 3 （NLRP3） inflammasomes and alleviating the acute liver injury （ALI） induced by lipopolysaccharide （LPS） in the mouse model of sepsis. MethodFifty-four male C57BL/6 mice were randomized into blank， model， low- （3.08 g·kg^-1）， medium- （6.15 g·kg^-1）， and high-dose （12.30 g·kg^-1） Huanglian Jiedutang， and positive control （dexamethasone） groups （n=9）. The mice were administrated with Huanglian Jiedutang at different doses by gavage for 7 days， and then LPS （15 mg·kg^-1） was injected intraperitoneally for the modeling of sepsis. In the positive control group， dexamethasone （0.05 g·kg^-1） was injected intraperitoneally 1.5 h after modeling， and the mouse sepsis score （MSS） was recorded 12 h after modeling. The mice were sacrificed for the collection of blood and liver tissue samples. The levels of alanine transaminase （ALT） and aspartate transaminase （AST） were measured by a biochemical analyzer. The levels of tumor necrosis factor （TNF）-α， interleukin （IL）-6， IL-1β， and IL-18 in the serum were measured by enzyme-linked immunosorbent assay kits. Hematoxylin-eosin staining was used to observe the pathological changes in the liver tissue. The content of NLRP3 was observed by the immunofluorescence assay. The expression of apoptosis-associated speck-like protein containing CARD （ASC） was detected by immunohistochemistry. The protein levels of NLRP3， ASC， Caspase-1， and gasdermin D （GSDMD） in the liver tissue were determined by Western blot. Real-time quantitative polymerase chain reaction（Real-time PCR） was employed to determine the mRNA levels of GSDMD， Caspase-1， IL-1β， and IL-18. ResultCompared with the blank group， the model group showed elevated levels of ALT and AST （P<0.01） and risen levels of inflammatory cytokines in the serum （P<0.01）. In addition， the modeling resulted in edema and necrosis in the liver， and up-regulated the protein levels of GSDMD， NLRP3， ASC， and Caspase-1 （P<0.01） and the mRNA levels of GSDMD， Caspase-1， IL-1β， and IL-18 （P<0.01）. Compared with the model group， the drug intervention groups showed reduced content of inflammatory cytokines （P<0.01）， alleviated pathological damage in the liver tissue， and down-regulated protein levels of GSDMD， NLRP3， ASC， and Caspase-1 （P<0.05，P<0.01） and mRNA levels of GSDMD， Caspase-1， IL-1β， and IL-18 （P<0.05，P<0.01） in the liver tissue. ConclusionHuanglian Jiedutang can inhibit pyroptosis and reduce inflammation by inhibiting the activation of NLRP3 inflammasomes， thus demonstrating a therapeutic effect on acute liver injury in the mouse model of sepsis induced by LPS.

In this study, the pharmacodynamic substance basis of the therapeutic activity of different origin sources of the Tibetan medicinal herb Zha xun was evaluated, and the protective effect of the Zha xun, from Habahe county of Altay region, Xinjiang Uygur Autonomous Region; Gilgit region, Pakistan; Lhozhag county of Lhozhag city, Tibet Autonomous Region; Lhorong county of Chamdo city, Tibet Autonomous Region; and Jiulong county of Ganzi Tibetan Autonomous Prefecture, Sichuan Province, on 0.2% carbon tetrachloride (CCl₄)-induced acute liver injury in ICR mice was evaluated. The results showed that different sources of Zha xun significantly reduced serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH) in the CCl₄-induced acute oxidative liver injury model, improved liver histopathological damage. Among them, Zha xun from Habahe County, Altay Region, Xinjiang Uygur Autonomous Region; Gilgit Region, Pakistan; and Lhorong County, Chamdo City, Tibet Autonomous Region significantly reduced the malondialdehyde (MDA) content in liver tissues (P < 0.05), increased the glutathione (GSH) content (P < 0.01), improved the oxidative stress in liver tissues. The preliminary evaluation of the hepatoprotective activity of Zha xun from different origins was carried out using the model of HepG2 cell injury induced by acetaminophen (APAP). The results showed that Zha xun from different origins could significantly inhibit APAP-induced hepatocellular injury and improve the survival rate of hepatocytes. The present study demonstrated that the different origins of Zha xun had definite hepatoprotective activities in vivo and ex vivo, among which, Zha xun from Lhorong County, Chamdo City, Tibet Autonomous Region, had stronger hepatoprotective activities. The animals used in this experiment and the related dispositions were in accordance with the requirements of animal welfare, and the experiment was approved by the Committee of Laboratory Animal Management and Use of the Institute of Pharmaceutical Sciences of the Chinese Academy of Medical Sciences (approval No. 00004024) before the experiment was carried out.
