By exploring theories related to yin-yang, body and spirit, and the relationship between nature and human beings, this study proposed the holistic functional perspective in Traditional Chinese Medicine (TCM) rehabi-litation. This perspective emphasizes the influence of various internal and external factors on the body's function and health status, with the integration of form and spirit as its core concept. It integrates the principles of correspondence between nature and human beings, as well as the unity of individuals and society, positioning holistic function as the key focus in TCM rehabilitation practice. It guides the prevention, assessment, and rehabilitation treatment of functional disorders, ultimately achieving the goal of comprehensive recovery of health. Additionally, the study reviewed the current application status of the holistic functional perspective in clinical TCM rehabilitation, clarified its integration throughout the entire TCM rehabilitation process, with the goal of providing a theoretical and practical foundation for further research and application in TCM rehabilitation.

ObjectiveTo assess the current status of medical waste management in Jinshan District of Shanghai, China, to identify existing issues, and to provide a scientific basis for formulating targeted strategies. MethodsData were collected from the routine supervision and inspection records of the Jinshan District Health Commission Supervision Institute from 2017 to 2021, covering all aspects of medical waste management, including collection, classification, transportation, storage, and administrative penalties. ResultsThe compliance rates for the establishment of institutional frameworks, staffing, internal handover, and registration in medical and healthcare institutions all exceeded 95.00%. However, only 2.31% of the medical and healthcare institutions met the 48-hour storage limit requirement for medical waste. Private institutions had significantly lower compliance rates (P<0.05) in aspects such as proper classification and collection, maintaining records for three years, adhering to the 48-hour storage limit, refraining from commercial transactions, timely disinfection and cleaning, and implementing emergency measures for waste loss. Compliance rates also varied among different types of institutions regarding the establishment of temporary storage facilities and the implementation of the transfer manifest system, with community healthcare institutions exhibiting relatively lower compliance rates (P<0.05). Over the past five years, private medical and healthcare institutions accounted for 63.33% of administrative penalty cases. ConclusionWhile medical waste management in Jinshan District, Shanghai, has gradually become more standardized, challenges remain. To address the issue of medical waste being stored for over 48 hours, medical waste transfer stations should be established to improve transfer efficiency and ensure complete waste collection. Additionally, for private and community healthcare institutions, weak links in management should be addressed by establishing medical waste quality control teams, enhancing supervision through digital tools, and optimizing management processes to comprehensively elevate medical waste management.

【Objective】 To observe the changes of coagulation factor activity and protein content of the thawed fresh frozen plasma (FFP) and fresh liquid plasma (FLP) during storage at 2-6℃, and to provide reference for exploring the appropriate storage time of FFP at 2-6℃ after thawing. 【Methods】 The small-thaw group and the large-thaw group were respectively detected for the activity of coagulation factor FⅤ (FⅤ∶C) and FⅧ(FⅧ∶C), and the levels of fibrinogen (Fib), total protein (TP) and albumin (Alb) in TTP at 1, 2, 3, 4, 5, 6 and 7 days after thawing. And the FLP was detected for FⅤ∶C, FⅧ∶C, Fib, TP and Alb at 1, 2, 3, 4, 5, 6, 7 days and 1, 6, 11, 16, 21, 26 and 31 days after preparation, respectively. 【Results】 In FFP group, FⅧ∶C decreased gradually with the prolongation of storage time after melting (P<0.05), and decreased by 37.4% and 47.6% respectively in the two groups on the 7th day. There was no statistical difference in FⅤ∶C, Fib, TP and Alb (P>0.05). In FLP group, FⅧ∶C decreased gradually with the prolongation of storage time after melting (P<0.05). There was no statistical difference in FⅤ∶C in 7-day storage group (P>0.05), but it decreased gradually in 31-day storage group (P<0.05). There was no statistical difference in Fib, TP and Alb (P>0.05). 【Conclusion】 Although FⅧ∶C is decreased in thawed FFP stored at 2-6℃ for 7 days, it is still about 52.4%, which should be able to play a normal role in clinical practice.

[Objective] To explore the clinical significance of the IgG1 and IgG3 subtypes of red blood cell unexpected antibodies. [Methods] The IgG1 and IgG3 typing tests were performed on the IgG type alloantibodies of Rh, Duffy and Kidd blood group systems detected in our hospital. Additionally, IgG1 and IgG3 titers were measured and monocyte monolayer assay was performed on 12 cases of anti-E to analyze the characteristics of different IgG subtypes of anti-E. [Results] Among the 115 cases of unexpected IgG antibodies, 81 cases of monospecific antibodies were predominantly IgG1 (58.02%, 47/81); 17 cases of mixed antibodies were predominantly IgG1+IgG3 (47.06%, 16/34). In monocyte monolayer assays, the phagocytic rate and antibody titer of IgG1 and IgG3 antibodies were positively correlated, while in IgG1+IgG3 complex antibodies, it was mainly associated with IgG3, with higher antibody titers correlating with higher phagocytic rates. When the anti-E titers were 32 for all, the IgG1+IgG3 complex had the highest phagocytosis rate, followed by IgG3 alone, and IgG1 alone had the lowest phagocytic rate. [Conclusion] Monospecific antibodies among unexpected antibodies are primarily IgG1, while mixed antibodies are mainly IgG1+IgG3. The results of MMA indicate that the immune response caused by the IgG1+IgG3 complex is more severe. Therefore, when antibodies like anti-E coexist with other antibodies, even if the titer is low, the immune response may still be severe, which should be taken seriously in clinical practice.

Objective:
To understand the mortality and probability of premature death due to malignant tumors, cardio-cerebrovascular diseases, diabetes and chronic respiratory diseases in Taizhou City, Zhejiang Province, so as to provide the basis for the improvement of chronic diseases prevention and control strategies.
Methods:
The death data of the four chronic diseases among local residents in Taizhou City from 2019 to 2022 were collected through Taizhou Chronic Disease Information Management System, and the crude mortality, standardized mortality (standardized by the data of the seventh national population census in 2020) and probability of premature death were calculated. The trends in mortality and probability of premature death were analyzed using annual percent change (APC). The attainment of probability of premature death due to the four chronic diseases were evaluated using the target values and predicted values in 2025 and 2030.
Results:
There were 119 899 deaths from the four chronic diseases in Taizhou City from 2019 to 2022, with the crude mortality of 494.48/105 and the standardized mortality of 410.68/105, which was no significant changing trend (APC=4.680% and -2.795%, both P>0.05). The probability of premature death decreased from 10.39% to 8.69% (APC=-6.027%, P<0.05). The crude mortality and standardized mortality in males were higher than those in females (562.13/105 vs. 424.08/105; 461.67/105 vs. 353.81/105; both P<0.05). The crude mortality and standardized mortality in rural areas were higher than those in urban areas (499.65/105 vs. 480.52/105; 429.20/105 vs. 365.68/105; both P<0.05). The probability of premature death in women and rural residents showed downward trends (APC=-8.210% and -7.558%, both P<0.05) from 2019 to 2022. The standardized mortality and probability of premature death due to malignant tumors showed downward trends (APC=-6.090% and -8.019%, both P<0.05). The crude mortality of diabetes showed an upward trend (APC=18.654%, P<0.05). The predicted values for probability of premature death due to due to the four chronic diseases in 2025 and 2030 were 7.27% and 5.40%, respectively, and were lower than the target values of 10.02% and 8.77%.
Conclusions
From 2019 to 2022, there was no significant trends in the mortality of four chronic diseases in Taizhou City, with rural men being the key population for prevention and control. The probability of premature death showed a downward trend, and it was expected to achieve the target in 2025 and 2030.

Objective:To explore the clinical phenotype, diagnosis, treatment and genetic characteristics of infants with lethal mitochondrial trifunctional protein deficiency (MTPD).Methods:The clinical data of one patient with lethal MTPD admitted to the neonatal department of Guilin Maternal and Child Health Hospital were retrospectively analyzed. Relevant literature published up to July 2023 were retrieved from the Chinese Science and Technology Journal database, CNKI, Wanfang Database, Chinese Medical Journal Full-text Database, Chinese Biomedical Journal Literature Database, China Biomedical Literature Database, PubMed, Elsevier ScienceDirect, Embase and BIOSIS Previews with the terms of "mitochondrial trifunctional protein deficiency", "mitochondrial trifunctional protein", "HADHA", "HADHB", "newborn", "infant" and "lethal". Then the characteristics of clinical phenotypes and genetic variations about MTPD infants were summarized.Results:This patient was a 33 +3 week premature male infant who developed symptoms 9 d after birth. The main manifestations were metabolic acidosis, recurrent apnea, shock, cardiomyopathy and heart failure. Blood tandem mass spectrometry reported an increased levels of multiple acylcarnitines, and genetic testing indicated that the patient's HADHB gene had maternal c.527C>G missense mutation and de novo c.1148C>T missense mutation. The infant was diagnosed with lethal MTPD and died 12 d after birth after his family gave up the treatment. There were 29 cases in the total 13 publications that were retrieved. Together with this case, there were 30 cases involved. Among the 16 cases with relatively complete data, 10 cases were male and 15 cases developed symptoms in neonatal period. The main clinical phenotypes were cardiomyopathy, abnormal myocardial enzyme spectrum, heart failure and lactic acidosis or metabolic acidosis. Among the 15 cases with clear age of death, 14 died within 3 months of life. Of the reported patients, only one survived at 8 years of age. 29 cases were confirmed through genetic test, 10 infants had HADHA gene variations and 19 had HADHB gene variations. Only one patient was confirmed by pathological detection and mass spectrometry analysis. Conclusions:MTPD is a rare autosomal recessive genetic disease. Lethal MTPD has an early onset with high mortality. Severe acidosis and heart failure are the most common symptoms in neonatal period. Early detection of acylcarnitine and HADHB, HADHA gene should be performed in highly suspected infants to help early genetic diagnosis and intervention.
