Traditional Chinese medicine （TCM） diagnostics is a discipline that studies the basic theories and fundamental skills of diagnostic methods， disease diagnosis， and differentiation in accordance with the theories of TCM. The artificial intelligence （AI） technology has gained remarkable achievements in the intelligentization of the four diagnostic methods in TCM and the standardization of differentiation and diagnosis. However， it still faces many challenges. The standardization of clinical data collection is difficult， and the data quality is uneven， which affects the usability of the data. The integration of the four diagnostic information is insufficient. Most instruments can only collect data from a single diagnostic method， lacking overall integrity. The scientific nature of the diagnostic model needs to be improved. The existing models lack dynamics and the reasoning logic of TCM differentiation. The accuracy of intelligent methods needs to be improved， and the existing evaluation indicators cannot fully reflect the practical application effect of the model. Furthermore， the relevant laws and regulations are still not perfect， and data security and patient privacy lack guarantees. The cultivation of compound talents is insufficient， and there is a lack of interdisciplinary talents who are proficient in both TCM and AI. On this basis， this paper expounded on the current development status， difficulties， and bottlenecks of AI in TCM diagnosis and then explored the development trend of AI in the field of TCM diagnosis. It proposed solutions such as optimizing the data collection process， constructing multimodal diagnostic models， facilitating multi-disciplinary exchanges and cooperation， improving laws and regulations， and cultivating compound talents. It is hoped that modern， standardized， normalized， and intelligent TCM diagnosis can be further promoted， thereby providing new impetus and methods for the inheritance and innovation of TCM.

Objective To compare the clinical characteristics of pneumococcal meningitis in different age groups, and to provide a basis for early diagnosis of pneumococcal meningitis. Methods Cerebrospinal fluid and/or serum samples were collected from 1742 suspected cases of meningitis in Baoji, Shaanxi Province from August 2013 to July 2019. Streptococcus pneumoniae was detected by isolation culture and real-time fluorescence quantitative polymerase chain reaction. Retrospective analysis of clinical manifestations, biochemical indicators and other information of laboratory confirmed cases was conducted by χ² test or Fisher's exact test. Results A total of 1742 samples of encephalitis or meningitis cases were detected, and 41 cases were confirmed as laboratory-confirmed Streptococcus pneumoniae infection. Among them, there were 12 cases (29.27%) in the infant group, 14 cases (34.15%) in the child group, and 15 cases (36.59%) in the adult group. The proportion of the adults with headache was significantly higher than that of the infants (χ²=11.408，P＜0.017). The proportion of the adults with consciousness disorder, elevated white blood cells and elevated neutrophils were significantly higher than those in the infant and the child groups（Fisher's exact test, P＜0.017；χ² =6.428，P＜0.017；χ² =10.898，P＜0.017；χ² =6.421，P＜0.017；χ² =9.758，P＜0.017；χ² =7.744，P＜0.017). The proportion of the infants with cerebrospinal fluid turbidity was significantly higher than that of the children (Fisher's exact test，P＜0.017). The proportion of the infants with decreased white blood cells and reduced glucose in cerebrospinal fluid was significantly higher than that of the children group and the adult group（Fisher's exact test, P＜0.001；Fisher's exact test, P＜0.001；Fisher's exact test, P＜0.017; Fisher's exact test, P＜0.017). Conclusion Most adult patients with pneumococcal meningitis have headache and consciousness disorders, with significantly increased proportion of white blood cells and neutrophils. Infant patients tend to have cloudy appearance of cerebrospinal fluid, leukopenia in blood, and decreased glucose in cerebrospinal fluid.

Chronic heart failure （CHF）， as the terminal stage of various cardiovascular diseases， is characterized by a prolonged course and a high mortality rate， posing a serious threat to human health and life. According to physician Sun Yikui's theory of "Mingmen Dongqi" （dynamic Qi of life gate） in the Ming Dynasty and the modern medicine concept of mitochondrial quality control （MQC）， this paper systematically explores the pathogenic mechanisms and evolutionary patterns of CHF， as well as its intrinsic connection with microstructural homeostasis， and further proposes potential traditional Chinese medicine （TCM） intervention strategies. CHF is often caused by damage to the heart Qi at the early stage. As the disease progresses， prolonged illness affects the kidneys， leading to the dynamic Qi decline of life gate. Further， it results in the failure of the functions of sustaining and consolidating， causing the disintegration of the physical form， which corresponds to mitochondrial kinetic disorders. The deficiency in primary driving force results in impaired Qi transformation， corresponding to mitochondrial autophagy dysfunction， forming a pathological transmission chain of "life gate-mitochondrion" that ultimately leads to myocardial structural disintegration and energy metabolism failure. Modern research indicates that patients with CHF exhibit significant MQC imbalance. Disrupted mitochondrial dynamics lead to network fragmentation， and impaired autophagy causes metabolic blockage， constituting the key microscopic mechanisms underlying ventricular remodeling and pump failure. Chinese herbal medicines， such as those with the effects of warming and tonifying kidney Yang or reinforcing healthy Qi， can intervene in multiple signaling pathways-including PTEN-inducible kinase 1 （PINK1）/Parkin and AMP-activated protein kinase/dynamin-related protein 1 （AMPK/Drp1）-to regulate mitochondrial dynamics and autophagy activity. This repairs damaged MQC networks and improves the microenvironment of myocardial energy metabolism. These intervention strategies align closely with the TCM therapeutic principles of warming and tonifying life gate， replenishing Qi， and activating blood， demonstrating the advantages of holistic regulation based on kidney-centered treatment and mitochondrial-targeted approaches. By integrating the "Mingmen Dongqi" theory with the MQC mechanism， this paper establishes a theoretical framework for the integrated prevention and treatment of CHF， offering new perspectives and insights for clinical practice and future research.

Chronic heart failure is the terminal stage of various cardiovascular diseases， and its occurrence and progression are closely associated with impaired myocardial energy metabolism and mitochondrial dysfunction. Mitochondrial dynamics maintain cardiomyocyte energy homeostasis through fusion， fission， and quality control. Disruption of mitochondrial dynamics may lead to mitochondrial network fragmentation， insufficient adenosine triphosphate （ATP） production， enhanced oxidative stress， and activation of ferroptosis. The theory of Yin at peace and Yang being compact originates from the Chapter Discussion on Interrelationship between Life and Nature in the Plain Questions， and emphasizes that the dynamic balance between Yin and Yang is fundamental to normal life activities. According to this theory and mitochondrial dynamics， this paper explores the pathogenic connotations of Yang failing to remain compact and Yin failing to remain at peace in chronic heart failure. In traditional Chinese medicine （TCM）， chronic heart failure is characterized by deficiency in origin and excess in manifestation. Deficiency of heart Qi and Yang is the root， often accompanied by Yang deficiency or Yin deficiency， while blood stasis， phlegm turbidity， and water retention constitute the manifestations. When Yang fails to remain compact， cardiac propulsion becomes weakened and Qi transformation is impaired. When Yin fails to remain at peace， Yin pathogens are generated and Yin essence is consumed. At the microscopic level， imbalance of mitochondrial dynamics is manifested as insufficient mitochondrial fusion， excessive fission， reduced energy production， excessive ROS generation， expansion of the labile iron pool， and accumulation of lipid peroxidation products， which contribute to Yin-Yang imbalance in chronic heart failure. Furthermore， by integrating formula-pattern correspondence and the approach of inferring patterns from formula effects， this paper summarizes the possible molecular phenotypes corresponding to different syndrome elements and syndrome patterns. It further proposes keeping Yang compact and keeping Yin at peace as therapeutic principle for chronic heart failure， aiming to restore energy metabolism homeostasis by regulating mitochondrial dynamics with TCM and to provide new perspectives and ideas for the treatment of chronic heart failure.

Objective:To estimate the incidence of Bordetella pertussis（ Bp）infection by analyzing the seroepidemiological characteristics of pertussis in healthy people aged 1-14 years in Shaanxi Province in 2017. Methods:A stratified random sampling method was used to select healthy people aged 1-14 years from 30 county-level disease surveillance sites in 10 cities of Shaanxi Province in 2017. Serum IgG antibodies against pertussis toxin（PT-IgG）were quantitatively detected by ELISA. The incidence of Bp infection within one year（PT-IgG≥100 IU/ml）and the geometric mean concentration（GMC）of PT-IgG were analyzed. Statistical analysis was performed using Mann-Whitney U test，Kruskal-Wallis test，or Jonckheere-Terpstra test. Results:A total of 1 777 subjects were included. The incidence of Bp infection within one year was 0.84%（15/1 777）and the GMC of PT-IgG was 5.70 IU/ml. The incidence of Bp infection within one year in different age groups ranged from 0 to 3.06%（3/98），and the GMC of PT-IgG was between 2.99 IU/ml and 9.29 IU/ml. People aged 12-14 years showed higher incidence of Bp infection within one year. The estimated incidence of Bp infection in people aged 5-14 years was 6 639.97/100 000，with the lowest incidence in people aged 5-6 years（2 016.85/100 000）and the highest in people aged 13-14 years（15 425.95/100 000）. The estimated incidence of Bp infection increased with age（ χ 2trend=12 090， P<0.01）. Conclusions:The actual incidence of Bp infection in healthy people aged 1-14 years in Shaanxi Province is high，and the duration of antibody responses to vaccination is limited. Children and adolescents are high-risk groups for pertussis，and attention should be paid to people aged 12-14 years. It is recommended to strengthen the routine monitoring of pertussis in order to better adjust and optimize the immunization strategy.

Objective:To investigate the safety of the tetravalent meningococcal conjugate vaccine (MPCV-ACYW) in combination with the inactivated poliomyelitis (IPV) vaccine and diphtheria-tetanus-acellular pertussis (DTaP) vaccine for infants aged 3-5 months and provide real-world evidence for the immunization strategy of vaccine combination.Methods:From June to October 2023, a total of 600 3-month-old infants were selected and divided into three groups: control group, mono-vaccination group and combined vaccination group. They were simultaneously or individually vaccinated with MPCV-ACYW, IPV and DTaP vaccines at 3, 4, and 5 months of age, respectively. The incidence rate of adverse reactions within 30 days after each dose was observed.Results:All 600 infants completed at least one vaccination and entered the safety data analysis. The age of the control group (100 infants), the mono-vaccination group (250 infants), and the combination group (250 infants) was (101.20±7.88), (102.26±7.94), and (102.35±7.76) days, respectively. The body lengths were (63.00±3.02), (62.55±3.06), and (63.14±4.02) cm, respectively. The body weights were (6.90±0.77), (6.86±0.94), and (6.99±0.95) kg, respectively. Boys accounted for 49%, 50.4%, and 52.4%, respectively, with no statistically significant differences (all P>0.05). The overall incidence rates of adverse reactions in the control group, mono-vaccination group, and combined vaccination group were 4.00%, 2.80%, and 3.20%, respectively, with systemic adverse reaction rates of 3.00%, 2.40%, and 2.00%. The incidence rates of local adverse reactions were 1.00%, 0.40%, and 1.20%, with no statistically significant differences (all P>0.05). Adverse reactions were mainly grade 1, with incidence rates of grade 1 adverse reactions of 3.00%, 2.00%, and 1.60% in the three groups, and incidence rates of grade 2 adverse reactions of 1.00%, 0.80%, and 1.60%, respectively. No grade 3 or 4 serious adverse reactions occurred, and the differences were not statistically significant (all P>0.05). The adverse reaction symptoms of the three groups were mainly systemic reactions, among which fever and diarrhea symptoms were reported in individual cases in each group, with no statistically significant differences in the incidence rate (all P>0.05). The symptoms of adverse reactions were mostly transient and self-relieved, all of which were cured. Conclusion:The combination of MPCV-ACYW and IPV or DTaP vaccines is safe for infants aged 3-5 months.

From 2019 to 2023, a total of 30.8602 million doses of non-National Immunization Program (non-NIP) vaccines were administered in Shaanxi Province, averaging 1 561 doses per 10 000 population. The annual administration of non-NIP vaccines increased from 4.359 1 million doses in 2019 to 7.858 2 million doses in 2023, with their proportional representation among all vaccines rising from 30.82% to 55.15%( χ2 trend=2 440 581.54, P<0.001). The administration rate per 10 000 population increased from 1 105 doses to 1 986 doses during this period( χ2 trend=373.10, P<0.001). Concurrently, the substitution rate of non-NIP vaccines for National Immunization Program vaccines rose from 4.94% in 2019 to 16.11% in 2023.

Respiratory syncytial virus (RSV) is a common pathogen that causes acute respiratory infections, especially in infants and young children. There are currently no RSV-specific antiviral drugs, and there are no approved vaccines for infants and young children. With the widespread use of RSV passive immunizations in infants and young children in 2022 and the effective reduction of the burden of RSV infection-related diseases, passive immune-prophylaxis of RSV infection has attracted more and more attention. This paper summarizes the implementation experience and real-world application effect of passive immune-prophylaxis for RSV infection at home and abroad, to provide reference for the immune-prophylaxis practice of passive immune-prophylaxis for RSV infection in infants and young children in China.
