Healthy dental pulp is essential for preserving teeth and maintaining their normal function. Vital pulp therapy (VPT) is widely used in clinical applications because it aims to preserve vital pulp and enhance the long-term survival of teeth. An accurate diagnosis of pulp vitality is a prerequisite for successful VPT. However, accurately assessing pulp viability remains challenging in clinical practice. Pulp viability is influenced by various factors, including the type of pulp exposure, caries status, periodontitis, trauma, treatment factors, patient age, and individual differences. Assessing pulp viability requires a comprehensive consideration of medical history and clinical manifestations, along with a combination of various auxiliary methods, such as pulp sensibility tests, pulp blood flow tests, imaging techniques and molecular diagnostics. In the future, the technology for assessing pulp vitality should evolve toward chairside, visualization, and precision techniques, to achieve consistency between clinical and histological diagnoses, thereby providing patients with the most effective treatment.

The paper introduces 5 books written by WANG Mengying, including Suixiju Chongding Huoluan Lun, Guiyan Lu, Wenre Jingwei, Wang Mengying Yi'an and Suixiju Yinshipu; and analyzes the ideas of diagnosis and treatment of cholera and the academic thoughts in treatment with acupuncture-moxibustion therapy. In pathogenesis, cholera is classified into cold and heat types. Cholera of heat type roots on qi and blood. If the pathogenic factors are mild and located shallowly, the sneezing method, followed by scraping method, is adopted to open meridians and collaterals, as well as the qi level, so as to eliminate pathogens. When the pathogens go deeply, the bloodletting technique is used to clean the toxic heat in blood level and reduce the reversed qi. For cholera of cold type, warm ironing moxibustion is delivered to promote qi circulation and disperse cold, and improve qi movement. If spasm and syncope occur in cholera, no matter of cold or heat identification, the emergent measure is operated with the external application of pungent, warm and salty herbal plaster at Yongquan (KI1). When the pathogens are almost eliminated, the herbal medicines are combined to treat the symptoms and remove the causative factors of the disease.

OBJECTIVE:
To investigate the current status of kinesiophobia after lumbar fusion surgery in patients with lumbar disc herniation (LDH) and to analyze its influencing factors.
METHODS:
A total of 489 LDH patients who underwent lumbar fusion surgery in our hospital from January 2021 to December 2022 and effectively filled out the tampa scale for kinesiophobia (TSK) and other questionnaires on the first day after surgery were collected as the study subjects, the current status of kinesiophobia in LDH patients after lumbar fusion surgery were investigated using the TSK. The LDH patients were grouped into a kinesiophobia group (n=221) and a non kinesiophobia group (n=268) based on whether there was kinesiophobia after lumbar fusion surgery. The self-designed general data questionnaires were used to collect data, and Logistic regression was applied to analyze independent risk factors for kinesiophobia after lumbar fusion surgery in the LDH patients.
RESULTS:
In the study, 221 out of the 489 LDH patients (45.19%) had kinesiophobia after lumbar fusion surgery. Univariate analysis showed that there were statistically significant differences between the phobic group and the non phobic group in terms of gender, education level, course of disease, whether there was hypoproteinemia, pain level, self-efficacy, social support, whether there was anxiety, and whether there was depression (P < 0.05). There were no statistically significant differences in terms of age, body mass index, monthly family income, marital status, residence, medical expense payment form, whether there was hypertension, whether there was diabetes, whether there was cardiovascular and cerebrovascular disease, whether there was respiratory disease, whether there was surgery experience, whether there was anemia, work conditions, and responsibility segments (P>0.05). Male (95%CI: 3.289-10.586, P < 0.001), education level below undergraduate level (95%CI: 6.533-45.162, P < 0.001), severe pain (95%CI: 10.348-72.025, P < 0.001), moderate pain (95%CI: 6.247-37.787, P < 0.001), low self-efficacy (95%CI: 4.238-15.095, P < 0.001), and medium self-efficacy (95%CI: 2.804-8.643, P < 0.001) were influencing factors for kinesiophobia after lumbar fusion surgery in the patients with LDH (P < 0.05).
CONCLUSION
The incidence of kinesiophobia after lumbar fusion surgery in patients with LDH is high, and its influencing factors include gender, education level, pain level, and self-efficacy.

Objective:To investigate the incidence of collateral circulation in high-risk patients with sleep apnea and stroke treated by continuous positive airway pressure (CPAP) ventilation and to analyze the influencing factors. Methods:A total of 152 patients diagnosed with obstructive sleep apnea-hypopnea syndrome (OSAHS) combined with acute ischemic stroke (AIS) who were admitted to our hospital from January 2020 to June 2022 were selected for this study. Based on the apnea-hypopnea index (AHI), the patients were divided into three groups: mild (n=44), moderate (n=72), and severe (n=36). After treatment, the patients were further classified into a group without collateral circulation (n=30) and a group with collateral circulation (n=26), which included those with moderate collateral circulation (n=69) and good collateral circulation (n=27). Clinical data across the different groups were compared, and multiple factor analysis was performed to identify factors affecting the occurrence of collateral circulation. Results:The AHI and IL-6 levels in the severe group were significantly higher than those in the mild and moderate groups, while the levels of NO and PO2 were significantly lower in the severe group compared to the mild and moderate groups, with statistically significant differences among the three groups (P<0.05). After treatment, all groups showed improvement, and the proportion of patients with collateral circulation was 84.09% in the mild group, 81.94% in the moderate group, and 72.22% in the severe group. Significant differences in age, AHI, NIHSS, NO, MoCA, and MMSE scores were observed between the groups with and without collateral circulation (P<0.05). In the group with collateral circulation, the scores for age, AHI, and NIHSS in the good collateral circulation subgroup were significantly lower than those in the poor collateral circulation and moderate collateral circulation subgroups, while the scores for NO, MoCA, and MMSE were significantly higher in the good collateral circulation subgroup. Multi-factor analysis revealed that age, AHI, and NIHSS were independent risk factors for collateral circulation, whereas NO, MoCA, and MMSE served as protective factors that were negatively correlated with collateral circulation. Classification tree model results indicated that AHI had the greatest influence on the occurrence of collateral circulation among the five influencing factors, demonstrating good predictive capability. Conclusion:Most high-risk patients with sleep apnea and stroke are likely to develop collateral circulation following continuous positive airway pressure ventilation. Factors such as age, AHI, NIHSS, NO, MoCA, and MMSE are important determinants affecting the occurrence of collateral circulation.

OBJECTIVES:
This study aimed to investigate the incidence, imaging characteristics, and clinical manifestations of the eruption failure of deciduous molars using panoramic radiographs to provide a foundation for diagnosis and treatment in this population.
METHODS:
This study retrospectively reviewed panoramic radiographs of children aged 4-8 years obtained from Stomatology Hospital, Zhejiang University School of Medicine between January 2021 and December 2023. A total of 31 331 subjects were included for the radiographic assessment of the tooth eruption failure of deciduous molars. Incidence, radiographic characteristics, and associated complications were documented. Statistical analysis was performed using SPSS 26.0.
RESULTS:
The incidence of the eruption failure of deciduous molars among children aged 4-8 years was 0.94% (296/31 331). The rate was 1.55 times higher in females than in males, demonstrating a significant gender difference (P<0.001). Among the affected deciduous molars, mandibular first deciduous molars accounted for 76.4%, followed by the mandibular second deciduous molars (13.8%), and the maxillary deciduous molars collectively comprised 9.8%. The severity of eruption disorders was significantly associated with the mesial and distal tilting of adjacent teeth and elongation of the antagonist (P<0.001).
CONCLUSIONS
The incidence of the eruption failure of deciduous molars in children aged 4-8 years was 0.94%, with a high prevalence in females and a predilection for the mandible, particularly the mandibular first deciduous molar. For deciduous molars with severe eruption failure, early intervention is crucial to mitigate complications such as malocclusion and space loss.

Astrocytes are heavily activated in Alzheimer's disease,engulfing damaged synapses,Aβ proteins,Tau proteins,apoptotic cells and other substrates.However,these substrates are difficult to degrade,accumulate as the disease progresses,and impair the phagocytosis of astrocytes.During phagocytosis,astrocytes recognize different substrates through a variety of phagocytosis receptors and partially degrade the substrates through degrad-ing enzymes and lysosomal pathways.The accumulation of Aβ and Tau proteins in astrocytes caused astrocyte im-mune and metabolic disorders,and Aβ toxicity changed after phagocytosis.In addition,astrocytes and microglia form a complementary pattern and cooperate to complete phagocytosis through interaction.Regulating the pathway of astrocyte phagocytosis and degradation is believed to be a potential novo therapeutic for clinical treatment of Alzheimer's disease.

ObjectiveTo explore the effect of Tanreqing injection combined with Ceftazide on the clinical efficacy, lung function, and laboratory inflammatory index of patients suffering from phlegm heat obstructing lung syndrome in acute exacerbation of chronic obstructive pulmonary disease (AECOPD). MethodFrom June 2021 to June 2023, 76 patients diagnosed with phlegm heat obstructing lung syndrome in AECOPD were enrolled in the respiratory and critical medical department of Jieshou Hospital of Traditional Chinese Medicine. They were randomly divided into a control group and an observation group with 38 cases each. The control group used Ceftazidime intravenous drip and other conventional oxygen inhalation and antispasmodic treatment measures of western medicine. The observation group received Tanreqing injection intravenous drip based on the treatment of the control group, with a course of 10 days. The changes of laboratory indicators such as hs-CRP, calcitonin (PCT), and interleukin-6 (IL-6) before and after treatment were analyzed, and the improvement of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), one second rate (FEV1/FVC), assessment and improvement of the British Medical Research Society’s dyspnea index (mMRC), self-evaluation test of chronic obstructive pulmonary disease patients (CAT), and traditional Chinese medicine syndrome score was compared. In addition, the total effective rate between the two groups after treatment was compared. ResultAfter treatment, the hs-CRP, PCT, IL-6, FEV1, FVC, FEV1/FVC, mMRC, CAT scores, and traditional Chinese medicine syndrome evaluation of both groups improved (P<0.01). After treatment, compared with the control group, the observation group showed more significant improvements in hs-CRP, PCT, IL-6, FEV1, FVC, FEV1/FVC, mMRC, CAT scores, and traditional Chinese medicine syndrome evaluation, and the difference was statistically significant (P<0.05,P<0.01). The total clinical effective rate of the control group was 86.84% (33/38), while that of the observation group was 94.74% (36/38). The therapeutic effect of the observation group was better than that of the control group (χ2=8.471, P<0.05). ConclusionTanreqing injection combined with Ceftazidime has obvious efficacy in the treatment of phlegm heat obstructing lung syndrome in AECOPD, which is better than the treatment of Ceftazidime antibiotics alone. It can reduce the risk of acute exacerbation, alleviate clinical symptoms, and delay the decline of lung function.
