Guided by Academician Zhang Boli's theory of "dampness， turbidity， phlegm， and fluid-related diseases"，this paper elaborated on the pathogenesis and syndrome differentiation treatment of heart failure from the perspective of the "spleen-mitochondria". It analyzed the essential similarities between "spleen-mitochondria" and "dampness， turbidity， phlegm， and fluid-related diseases"， as well as their close association with the onset of heart failure. Furthermore，it explored the connection between spleen function and mitochondrial function in traditional Chinese medicine （TCM），positing that the spleen's role in transportation and transformation is analogous to mitochondrial material metabolism and energy conversion，with spleen deficiency closely related to mitochondrial dysfunction. It thus concluded that mitochondrial material metabolism and energy conversion represent the microscopic essence of the spleen's role in transportation and transformation，and mitochondrial dysfunction is a contributing factor to pathological products like dampness and turbid phlegm，which are closely associated with the occurrence of heart failure. The four elements of dampness，turbidity，phlegm，and fluid are a series of related symptoms resulting from abnormal fluid transportation and transformation，serving as both factors in the onset of heart failure and the core pathological basis for its deterioration. Therefore，during the treatment of heart failure，it is essential to regulate mitochondrial function. Early intervention should focus on eliminating dampness and turbidity to improve mitochondrial function and restore normal energy metabolism. In the middle and late stages，emphasis should be placed on resolving phlegm，promoting blood circulation，warming Yang，and reducing water retention to alleviate mitochondrial damage and improve cardiac function. Supporting Qi and strengthening the spleen should be a continuous approach，and treatment should be adjusted to enhance mitochondrial function and stabilize the condition，thereby improving prognosis. This paper discussed the role of the spleen and mitochondria in the pathogenesis of heart failure，examined the evolution of heart failure mechanisms from the perspective of dampness， turbidity， phlegm， and fluid-related diseases，and proposed a phased treatment strategy. It enriched the theory of dampness， turbidity， phlegm， and fluid-related diseases and offered new strategies for heart failure treatment. However，in practical application，TCM strategies for treating heart failure need to be integrated with modern medical approaches to provide a more solid scientific foundation for treatment.

ObjectiveTo understand the status of parasitic infection in the food sold on market in Qingpu District of Shanghai, and to provide an evidence for the development of prevention and control strategies for parasitic infection applicable to Qingpu District. MethodsAquatic products, meat products and other foodstuffs sold on online shops, at farm product markets, supermarkets/foodstores and restaurants were sampled in Qingpu District, Shanghai, during 2015‒2023, based on the administrative division of Qingpu District. The parasitic infection in the food samples were examined using pressing method and digestion for detecting metacercariae in freshwater products and pickled products, using dissection microscopy for Anisakis larvae in seawater products, Taenia cysticercus and Trichinella encysted larvae in meat products. ResultsA total of 1 079 samples of food products were examined during 2015‒2023, with a total parasite infection rate of 13.44%. The total parasite infection rate of freshwater fish products was 3.40% (16/471), and the difference of parasite infection rates between different freshwater fish species was statistically significant (χ²=229.609, P=0.001). The total infection rate of Clonorchis sinensis was 3.18% (15/471), which had been detected in Pseudorasbora parva, Cyprinidae rhodeus, and Carassius auratus, with a positive rate of 77.78% (7/9), 50.00% (5/10) and 3.90% (3/77), respectively. Metorchis orientalis was detected in in Pseudorasbora parva, with a positive rate of 33.33% (3/9). The positive rate of Gnathostoma spinigerum (third-stage larvae) was 0.81%. Paragonimus metacercariae were not detected in the freshwater shrimps and crabs. The infection rate of seawater fish products was 26.46%. The difference of parasite infection rate in seawater fishes was statistically significant (χ²=109.181, P=0.001). A total of 53 pork and beef samples were tested, none was detected with Trichinella larva cysts, Taenia solium metacercariae, and Taenia saginata metacercariae. The total infection rate of pickled yellow mud snail products was 58.11% (43/74). Paragonimus metacercariae was not detected in any of the pickled aquatic product samples. ConclusionThere are different degrees of parasitic infection in freshwater products, seawater products and pickled aquatic products in Qingpu District of Shanghai. The risk of parasite infection from raw or undercooked foods is high. Health education on healthy dietary practices such as throughly cooked food should be strengthened for local residents.

Objective: To investigate the mechanism by which serum amyloid P component (SAP) alleviates periodontitis in mice, providing an experimental basis to establish SAP as a novel therapeutic agent for periodontitis. Methods: Ethical approval was obtained from the Institutional Animal Ethics Committee. Periodontitis models were established in wild-type (WT) mice and SAP-transgenic (SAP-Tg) mice, divided into four groups: WT control (WT group), WT periodontitis (WT+P group), SAP-Tg control (Tg group), and SAP-Tg periodontitis (Tg+P group). On day 7, the mice were euthanized, and periodontal tissues, teeth, and alveolar bone were collected. SAP protein expression was detected by enzyme-linked immunosorbent assay (ELISA). Micro-CT and HE staining were used to measure alveolar bone resorption (distance from the cementoenamel junction to the alveolar bone crest). Tartrate-resistant acid phosphatase (TRAP) staining was performed to assess osteoclast number, and immunohistochemistry (IHC) was employed to evaluate macrophage infiltration. The expression levels of inflammatory cytokines including interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were measured by qRT-PCR. Oral microorganism composition was analyzed using 16S ribosomal RNA (16S rRNA) gene sequencing. Additionally, macrophages from WT and SAP-Tg mice were isolated to establish an in vitro inflammation model, divided into WT+LPS and Tg+LPS groups. The expression of macrophage polarization-related genes including inducible nitric oxide synthase (iNOS), CD86, CD163, and CD206) were assessed by qRT-PCR. After the induction of osteoclast differentiation, TRAP staining was performed. Results: ELISA results demonstrated that periodontal tissues from Tg+P group mice exhibited higher levels of SAP expression compared to the WT+P group. Micro-CT and HE staining analyses revealed that the Tg+P group showed reduced alveolar bone resorption, indicated by a shorter distance between the cementoenamel junction and alveolar bone crest, compared to the WT+P group. Furthermore, TRAP staining results indicated a decrease in osteoclast numbers in the Tg+P group compared to the WT+P group. IHC and qRT-PCR results indicated reduced macrophage infiltration and decreased expression of IL-1β, IL-6, and TNF-α in the Tg+P group. Oral microorganism sequencing showed no significant difference in periodontitis-associated pathogenic bacteria between WT+P and Tg+P groups. In vitro experiments demonstrated that compared to the WT+LPS group, the Tg+LPS group exhibited downregulated M1 macrophage markers (iNOS and CD86) and upregulated M2 macrophage markers (CD163 and CD206). TRAP staining confirmed fewer osteoclasts in the Tg+LPS group. Conclusion SAP overexpression effectively alleviates periodontitis severity in mice by inhibiting M1 macrophage polarization, reducing pro-inflammatory cytokine expression, and suppressing osteoclast differentiation, thereby attenuating alveolar bone resorption.

Venous malformation is a common congenital, non-tumor vascular malformation, accounting for about 60% of all vascular malformations, of which 40% occur in the head and neck. Due to the complex anatomical structure of the oral and maxillofacial region and the diverse classification of venous malformations, their clinical treatment poses certain difficulties and challenges. This article systematically elaborates on the etiology, clinical manifestations, imaging features, and clinical treatment strategies of venous malformations in the oral and maxillofacial region. Molecular genetic studies have shown that the occurrence and development of venous malformations are closely related to abnormal activation of the ANGPT/TIE2/PI3K/AKT/mTOR signaling pathway; its clinical manifestations are gradually growing blue purple masses and its histological features are tortuous venous ducts; and clinical imaging examinations have high specificity, among which digital subtraction angiography classification has important clinical guidance value for the treatment of venous malformation sclerosis. According to different classifications, strategies, such as sclerosis treatment, surgical treatment, and laser treatment, can be applied separately or in combination. This article also explores the advantages and disadvantages of targeted therapy in the treatment of venous malformations, with a focus on improving clinical outcomes while reducing complications. At the same time, through the analysis of typical clinical cases, it summarizes the key points of diagnosis and treatment and treatment plans, in order to provide a reference for improving the clinical efficacy of venous malformation treatment and reducing treatment complications.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Objective To explore the prognostic value of serum gap connexin 43(Cx43)and galectin-9(Gal-9)levels in elderly patients with acute cerebral infarction(ACI)after ultra-early intravenous thrombo-lytic therapy.Methods A total of 106 elderly patients with ACI who received ultra-early intravenous throm-bolytic therapy in the hospital from September 2020 to September 2022 were selected as the study group,and 100 healthy subjects who came to the hospital for physical examination during the same period were selected as the health group.The levels of Cx43 and Gal-9 in serum of all subjects were detected by enzyme-linked im-munosorbent assay(ELISA).After 2 weeks of treatment,106 elderly ACI patients were divided into good prognosis group(81 cases)and poor prognosis group(25 cases)according to the National Institutes of Health Stroke Scale(NIHSS)score.Receiver operating characteristic(ROC)curve was used to analyze the evaluation value of serum Cx43 and Gal-9 in the prognosis of ultra-early intravenous thrombolytic therapy in elderly ACI patients.Multivariate Logistic regression analysis was used to explore the influencing factors of poor prognosis of ultra-early intravenous thrombolytic therapy in elderly ACI patients.Results The levels of Cx43 and Gal-9 in the study group were higher than those in the health group(P＜0.05).The levels of Cx43 and Gal-9 in the poor prognosis group were higher than those in the good prognosis group(P＜0.05).The area under the curve(AUC)of serum Cx43 and Gal-9 for predicting the poor prognosis in elderly ACI patients was 0.721(95％CI:0.673-0.758)and 0.837(95％CI:0.787-0.886),respectively,and the AUC of combined detection of CX43 and GAL-9 was 0.901(95％CI:0.857-0.946).The proportion of hypertension in the poor progno-sis group was higher than that in the good prognosis group(P＜0.05).Hypertension(OR=3.487,95％CI:1.564-7.773),serum Cx43≥106.53 pg/mL(OR=4.586,95％CI:1.982-10.611),serum Gal-9≥11.84 ng/mL(OR=4.345,95％CI:1.957-9.648)were risk factors for poor prognosis in elderly patients with ACI after ultra-early intravenous thrombolysis(P＜0.05).Conclusion Serum Cx43 and Gal-9 are highly expressed in elderly ACI patients,which could be used to evaluate the prognosis of elderly ACI patients after ultra-early intravenous thrombolysis therapy,and their combined detection has higher evaluation value.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

Objective To explore the influencing factors of visual acuity recovery in patients with high myopia after posterior chamber phakic intraocular lens(ICL)implantation.Methods A prospective study was conducted on 210 pa-tients(420 eyes)with high myopia who underwent ICL implantation at the Second Affiliated Hospital of Zhengzhou Univer-sity from May 2021 to March 2023.The patients were divided into a good recovery group[best corrected visual acuity(BC-VA)recovery ≥0.3 D]and a poor recovery group(BCVA recovery＜0.3 D)based on their visual acuity recovery status three months after surgery.The baseline data of patients in the two groups were compared,and the factors affecting visual acuity recovery were analyzed using Logistic regression.The receiver operating characteristic(ROC)curve was used to an-alyze the predictive value of the Logistic regression model for poor visual acuity recovery in patients with high myopia after ICL implantation.Results Three months after surgery,149 patients(298 eyes)were in the good recovery group,and 61 patients(122 eyes)were in the poor recovery group.There were no significant differences in gender,age,years of myopi-a,body mass index,and academic performance between the two groups(all P＞0.05).The proportions of patients with corneal astigmatism＜1.30 D(55.74％),corneal diopter＜45 D(59.02％),Pittsburgh Sleep Quality Index(PSQI)＜7 points(63.93％),and average central radius of curvature[(7.82±0.27)mm]in the poor recovery group were lower than those in the good recovery group[83.89％,81.88％,85.91％,and(7.90±0.24)mm,respectively].The central flat me-ridian curvature(k1)of the anterior corneal surface[(43.27±1.43)D],steep meridian curvature(k2)of the anterior corneal surface[(44.84±1.53)D],and arch height[(628.49±67.28)μm]in the poor recovery group were higher than those in the good recovery group[(42.73±1.42)D,(44.12±1.47)D],and[(417.56±80.14)pm],with significant differences(all P＜0.05).Logistic regression analysis showed that corneal astigmatism,corneal diopter,k1,k2,arch height,and PSQI score were independent influencing factors of poor visual acuity recovery after ICL implantation in pa-tients with high myopia(all P＜0.05).ROC curve analysis showed that the area under the ROC curve for predicting poor visual acuity recovery after ICL implantation in patients with high myopia by Logistic regression model was 0.938(95％CI:0.896-0.966),the sensitivity was 83.61％,and the specificity was 91.95％(P＜0.05).Conclusion The visual acuity recovery after ICL implantation in patients with high myopia is affected by corneal astigmatism,corneal diopter,k1,k2,arch height,and PSQI score.The Logistic regression model based on these factors has high predictive value for visual acui-ty recovery after ICL implantation.

Objective:To establish a prediction model of risk factors for early Q-T interval prolongation after acute myocardial infarction (AMI), which helps prevent and reduce the occurrence of acute malignant events.Methods:This is a case-control study. A total of 100 patients with Q-T interval prolongation after AMI who received treatment at Heilongjiang Provincial Hospital from January 2018 to December 2022 were included in this study. An additional 100 patients without Q-T interval prolongation after AMI who concurrently received treatment in the same hospital were also included in this study. Two model groups, including model group 1 (with Q-T interval prolongation, n = 50) and model group 2 (without Q-T interval prolongation, n = 50), and two test groups, including test group 1 (with Q-T interval prolongation, n = 50) and test group 2 (without Q-T interval prolongation, n = 50), were designated. Logistic regression analysis was performed to construct a prediction model of risk factors for Q-T interval prolongation. The area under the receiver operating characteristic curve was determined to evaluate the prediction model. The value of the prediction model was validated in the test groups. Results:Multivariate logistic regression showed that female gender ( OR = 2.307, 95% CI: 0.09-0.91, P = 0.041) and heart failure ( OR = 3.087, 95% CI: 1.15-8.27, P = 0.025) were independent risk factors for early Q-T interval prolongation after AMI. The area under the receiver operating characteristic curve of the prediction model was 0.770, with a sensitivity of 84.0%, a specificity of 66.0%, the Jordan index of 0.44, and the corresponding optimal critical value of 0.43. This indicates good fit of the model. Conclusion:Female gender and heart failure are independent risk factors for early Q-T interval prolongation after AMI. The model constructed based on the above-mentioned risk factors fits well and has a high predictive value, which helps reduce the occurrence of early Q-T interval prolongation after AMI.
