ObjectiveBy exploring the influencing factors of readmission in patients with stable angina of coronary heart disease （CHD） based on real-world clinical data， to establish a risk prediction model of integrated traditional Chinese and western medicine， in order to provide a basis for early identification of high-risk populations and reducing readmission rates. MethodsA prospective clinical study was conducted involving patients with stable angina pectoris of CHD， who were divided into a training set and a validation set at a 7∶3 ratio. General information， traditional Chinese medicine （TCM）-related data， and laboratory test results were uniformly collected. After a one-year follow-up， patients were classified into a readmission group and a non-readmission group based on whether they were readmitted. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for readmission. A risk prediction model of integrated traditional Chinese and western medicine was constructed and visualized using a nomogram. The model was validated and evaluated in terms of discrimination， calibration， and clinical decision curve analysis. ResultsA total of 682 patients were included， with 477 in the training set and 205 in the validation set， among whom 89 patients were readmitted. Multivariate logistic regression analysis identified heart failure history ［OR = 6.93， 95% CI （1.58， 30.45）］， wiry pulse ［OR = 2.58， 95% CI （1.42， 4.72）］， weak pulse ［OR = 3.97， 95% CI （2.06， 7.67）］， teeth-marked tongue ［OR = 4.38， 95% CI （2.32， 8.27）］， blood stasis constitution ［OR = 2.17， 95% CI （1.06， 4.44）］， phlegm-stasis mutual syndrome ［OR = 3.64， 95% CI （1.87， 7.09）］， and elevated non-high-density lipoprotein cholesterol ［OR = 1.30， 95% CI （1.01， 1.69）］ as influencing factors of readmission. These factors were used as predictors to construct a nomogram-based risk prediction model for readmission in patients with stable angina. The model demonstrated moderate predictive capability， with an area under the receiver operating characteristic curve （AUC） of 0.818 ［95% CI （0.781， 0.852）］ in the training set and 0.816 ［95% CI （0.779， 0.850）］ in the validation set. The Hosmer-Lemeshow test showed good calibration （χ² = 4.55， P = 0.80）， and the model's predictive ability was stable. When the threshold probability exceeded 5%， the clinical net benefit of using the model to predict readmission risk was significantly higher than intervening in all patients. ConclusionHistory of heart failure， teeth-marked tongue， weak pulse， wiry pulse， phlegm-stasis mutual syndrome， blood stasis constitution， and non-high-density lipoprotein cholesterol are influencing factors for readmission in patients with stable angina of CHD. A clinical prediction model was developed based on these factors， which showed good discrimination， calibration， and clinical utility， providing a scientific basis for predicting readmission events in patients with stable angina.

Chronic obstructive pulmonary disease （COPD） is a common disease with a high incidence and mortality rate in the world. It is characterized by chronic inflammation and structural obstruction and is not completely reversible which will lead to shortness of breath caused by air retention and physical exertion. Traditional Chinese medicine proposes the concept of "lung collaterals"， which refers to the collateral vessels scattered throughout the lungs and lung system. The lung collaterals include the pulse collaterals and Qi collaterals. The blood circulation in the pulse collaterals belongs to Yin， distributed internally along the way. The Qi circulation in the Qi collateral belongs to Yang and is distributed externally. In western medicine， the pulse collaterals have an identity with large， medium， and small blood vessels， microvessels， and especially microcirculation. The Qi collateral encompasses systems such as the nervous， endocrine， and immune system. Pulmonary microvascular endothelial cells （HPMECs） are an important component of the pulmonary microvascular endothelium. Recent studies have found that HPMECs are the main damaged cells in the pathogenesis of COPD， mediating the occurrence and development of COPD. Traditional Chinese medicine can regulate HPMECs to treat COPD through multiple components， targets， and pathways， and has the advantage of reducing western medicine resistance and many side effects. Based on the "lung collateral theory"， this paper focused on HPMECs， and elaborated on the new connotation of traditional Chinese medicine in protecting HPMECs to treat COPD， aiming to provide new insights for the clinical treatment of COPD by protecting HPMECs.

Objective:To analyze the effect of continuous positive airway pressure (CPAP) on maternal and neonatal outcomes in pregnant women with obstructive sleep apnea syndrome (OSAS), especially on the incidence of hypertensive disorder in pregnancy (HDP) in women with moderate to severe OSAS.Methods:A total of 180 pregnant women with OSAS who were diagnosed through sleep monitoring during pregnancy due to high-risk factors of OSAS and registered in Peking University People′s Hospital from January 2021 to May 2024 were selected as the study subjects. Clinical data were collected from medical records for retrospective analysis. According to whether they received standardized treatment with CPAP, they were divided into the CPAP treatment group (42 cases) and the control group (138 cases). The CPAP treatment group consisted of 9 pregnant women with moderate to severe OSAS, while the control group consisted of 34 pregnant women with moderate to severe OSAS. The maternal and neonatal outcomes, the incidence of HDP, placental weight after delivery and placental weight/neonatal birth weight ratio were compared between the two groups.Results:(1) The average gestational age of pregnant women in the CPAP treatment group was higher than that in the control group [(38.7±1.0) vs (38.0±1.4) weeks], the proportion of infants small for gestational age (SGA) in the CPAP treatment group was lower [0 (0/42) vs 12.3% (17/138)], and the birth weight of infants in the CPAP treatment group was bigger [(3 396±475) vs (3 082±710) g); the differences between the two groups were statistically significant (all P<0.05). There were no significant differences between the CPAP treatment group and the control group in terms of delivery mode, rates of postpartum hemorrhage and preterm birth, umbilical artery blood gas analysis pH<7.1, lactate≥6.0 mmol/L, base excess<-12.0 mmol/L and the incidence of gestational diabetes mellitus and HDP (all P>0.05). (2) The placental weight of the CPAP treatment group was significantly lower than that of the control group [(554.0±70.6) vs (615.7±119.1) g], the placental weight/newborn birth weight ratio of the CPAP treatment group was significantly lower than that of the control group (median: 0.17 vs 0.19), and the differences were statistically significant (all P<0.05). (3) The incidence of HDP in pregnant women with moderate to severe OSAS in the CPAP treatment group was lower than that in the control group [1/9 vs 61.8% (21/34)], and the difference was statistically significant ( P<0.05). Conclusions:CPAP treatment could prolong the gestational age in pregnant women with OSAS, reduce the incidence of SGA, increase the birth weight of infants, and reduce the incidence of HDP in pregnant women with moderate to severe OSAS, and is worth promoting in clinical practice. The improvement of neonatal outcomes by CPAP treatment is closely related to the placenta, which is worthy of further exploration.

Objective To investigate the screening results and factors affecting abnormal detection rates among high-risk groups of esophageal cancer and to explore effective intervention measures. Methods We investigated and collected the information on gender, education level, age, marital status, symptoms of reflux esophagitis (heartburn, acid reflux, belching, hiccup, foreign body sensation in the pharynx, and difficulty swallowing), consumption of pickled vegetables, salt use, and esophageal cancer incidence of villagers in a natural village in Wenfeng District, Anyang City, Henan Province. Changes in reflux esophagitis symptoms in the high-incidence area of esophageal cancer before and after 16 years were observed, and the relationship of such changes with esophageal cancer was analyzed. Results In 2008, 711 cases were epidemiologically investigated, including 213 cases with one of the symptoms of reflux esophagitis such as heartburn, acid reflux, belching, hiccups, foreign body sensation in the pharynx, and difficulty swallowing (sorted in accordance with the abovementioned symptoms; if there are multiple symptoms, then the former is taken); 55 cases with at least two related symptoms, among which the most symptom was heartburn in 108 cases (15.1%); followed by acid reflux, belching, etc. In 2024, the same group of people was investigated, and eight people were missing because of relocation. A total of 703 people were successfully investigated, of which 189 cases (26.8%) had one of the symptoms of reflux esophagitis, such as heartburn (sorted in accordance with relevant symptoms, if there are multiple symptoms, then the former will be selected); 167 cases (23.7%) had at least two related symptoms, among which the most symptom was heartburn in 139 cases (19.7%); followed by acid reflux. Over 16 years, among the 703 people investigated, 45 cases had esophageal cancer and they had one or more of the abovementioned symptoms. No significant differences in the reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.26); no significant differences in the composition of reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.299). Conclusion The detection rate of reflux esophagitis-related symptoms in the population in a high-risk area of esophageal cancer has not decreased in the past 16 years, and the high-risk factors still exist. Esophageal cancer is closely related to reflux esophagitis, and clinical practice can provide early diagnosis and treatment for high-risk population.

ObjectiveTo construct a rat model of psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type）， and evaluate the macroscopic manifestations and microscopic indicators of the model. MethodsTwenty-two SD rats were divided into normal group （n=3）， common psoriasis group （n=5）， spleen deficiency and dampness obstruction syndrome （external dampness type） group （n=7）， and psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group （n=7）. The spleen deficiency and dampness obstruction syndrome （external dampness type） rat model was established through 32-week exposure to an artificially simulated high-humidity environment， while the common psoriasis model was developed via 7-day topical application of imiquimod cream， and these two approaches were combined to construct a composite model of psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type）. Rats in the normal group were housed under normal humidity conditions. The general state， tongue manifestation of rats were observed to evaluate the macroscopic syndrome manifestations； the microscopic syndrome manifestations of rats were evaluated through adipose tissue and liver tissue changes； the severity of psoriasis in rats was evaluated through skin pathological changes， psoriasis area and severity index （PASI）， proliferating cell nuclear antigen （PCNA） expression and spleen tissue changes； changes in rat CD4⁺ interferon-γ⁺ cells （CD4⁺IFN-γ⁺ cells）， CD4⁺ tumour necrosis factor-α+ cells （CD4⁺ TNF-α⁺ cells）， and forkhead framing protein P3⁺ regulatory T cells （CD3⁺CD4⁺FoxP3⁺ Treg cells） were detected by flow cytometry. ResultsMacroscopically， both the spleen deficiency and dampness obstruction syndrome （external dampness type） group and psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group exhibited manifestations of spleen deficiency and dampness obstruction， including lethargy， huddling behavior， dull and disheveled fur， as well as soft or loose stools and perianal soiling in some individuals； both these two groups displayed enlarged tongue， swollen， and moist tongue texture， accompanied by slippery tongue surface. Microscopically， compared to the common psoriasis group， the psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group showed increased epididymal fat index （P＜0.05）； compared to the normal group and spleen deficiency and dampness obstruction syndrome （external dampness type） group， the psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group demonstrated significantly elevated spleen mass （P＜0.05）， while hepatic gross morphology and HE staining revealed no significant histopathological changes across all groups. Dorsal skin lesions were markedly exacerbated in the psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group when compared to those in common psoriasis group. Both the common psoriasis group and psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group exhibited significantly higher erythema scores， scaling scores， infiltration scores， PASI total scores， and proportions of CD3⁺CD4⁺FoxP3⁺Treg cells compared to the normal group and spleen deficiency and dampness obstruction syndrome （external dampness type） group （P＜0.05）， with pronounced PCNA-positive expression observed in the epidermal basal layer and dermis； the psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） group displayed significantly increased proportions of CD4⁺TNF-α⁺cells compared to the spleen deficiency and dampness obstruction syndrome （external dampness type） group （P＜0.05）； whereas no significant differences were detected in CD4⁺IFN-γ⁺cell proportions among groups （P＞0.05）. ConclusionThe rat model of psoriasis with spleen deficiency and dampness obstruction syndrome （external dampness type） can be successfully constructed by artificially simulating a high-humidity environment combined with imiquimod induction.

Objective To investigate the relationship between tooth loss and the occurrence of esophageal cancer in a natural village in Wenfeng District, Anyang City, Henan Province. Methods A prospective cohort study was conducted to observe the occurrence of tooth loss and esophageal cancer among the asymptomatic residents of the natural village for 16 years from January 2008 to July 2024. Data were analyzed by chi-square test, binary logistic regression, and restricted cubic spline. Results Among the total population of 711 cases, 136 cases were lost to follow-up and 575 cases were included in the final statistics, including 45 cases with esophageal cancer. Significant statistical difference was found between esophageal cancer patients with and without tooth loss (P<0.05). Logistic regression analysis showed that tooth loss was associated with the occurrence of esophageal cancer (OR=3.977, 95%CI: 1.543-10.255). After the adjustment for confounders, tooth loss remained significantly associated with the occurrence of esophageal cancer (OR=3.038, 95%CI: 1.035-8.914). A nonlinear dose-response relationship was observed between the number of teeth lost and the incidence of esophageal cancer. When the number of teeth lost was less than 12, the risk of esophageal cancer increased with the number of teeth lost. When more than 12 teeth were lost, the risk of esophageal cancer decreased as the number of teeth lost increased. Conclusion Tooth loss is a risk factor for the occurrence of esophageal cancer in this natural village. When the number of teeth lost is less than 12, the risk of esophageal cancer increases with the number of teeth lost.
