This paper systematically reviewed the concept of authentication studies on traditional Chinese medicine （TCM） classics and the research achievements of scholars across historical and contemporary periods. We categorized the authentication studies on TCM classics into four types， including work-oriented authentication research， metho-dological studies on authentication， extended authentication research， and single-book authentication. Multiple methods were applied comprehensively， including investigating bibliographic documents of successive dynasties， analyzing the academic contents of medical books， studying the textual characteristics of medical books， examining the cited references in medical books， verifying the biographies of authors， and analyzing the interpolations and accretions in medical books， to distinguish the authenticity of TCM classics. The academic value of authenticity identification of TCM classics is concluded in three aspects，i.e. it serves as an important means to distinguish authenticity from falsehood in TCM classics， an important guarantee for inheriting the essence of TCM literature， and a key to unlocking the academic treasure trove of TCM classics and achieving inheritance-based innovation， which will lay a solid documentary foundation for constructing identification methodologies and standardized systems.

With the continuous deepening of medical insurance payment reform, the implementation of the ambulatory patient groups(APG) based point system for payment has posed new challenges to the quality management of outpatient electronic medical record writing, as well as the supervision and operation management of outpatient costs in hospitals. A certain hospital began information technology construction in July 2021. By introducing diagnostic grouping functions into the outpatient electronic medical record system, the hospital strengthened the standardization of medical record writing. It also established an intelligent audit system for medical insurance costs to conduct full-process supervision of outpatient medical expenses and developed an intelligent operation analysis system for outpatient APG to provide a basis for hospital operation management decisions and performance distribution. These measures effectively improved the quality of outpatient medical record, reduced outpatient medical costs, and optimized their structure. The application of the intelligent medical insurance audit system also effectively prevented certain non-compliant issues in medical insurance payments, which can provide a reference for other medical institutions.

Post-stroke depression (PSD) is a common emotional disorder after stroke, which can affect cognitive function of patients and have adverse effect on post-stroke recovery. Diffusion tensor imaging (DTI) can reveal the microstructure of white matter. At present, it has been applied in the study of the pathogenesis of various diseases. This article reviews the application of DTI technology in depression, stroke, and PSD, aiming to make early predictions of PSD from multiple perspectives to improve its outcomes.

Objective:To study the prevalence and distribution of adult thyroid diseases in urban and rural areas of Hebei Province.Methods:A multi-stage stratified cluster sampling method was used to select Renqiu City and Licun Town, Luquan City of Hebei Province as the urban and rural survey sites, respectively. Questionnaire survey, physical examination and thyroid B ultrasound examination were conducted on local permanent residents (&ge; 5 years of residencies) over 18 years old. The fasting venous blood sample was collected to determine the serum thyroid function indicaters.Results:A total of 2 650 adults were surveyed, including 1 393 urban residents and 1 257 rural residents (1 357 males and 1 293 females). A total of 435 patients with thyroid diseases were diagnosed, the detection rate was 16.42%. There were seven thyroid diseases, including subclinical hypothyroidism (60.92%, 265/435), Hashimoto's thyroiditis (34.02%, 148/435), hypothyroidism (4.83%, 21/435), simple goiter (3.22%, 14/435), hyperthyroidism (2.53%, 11/435), subclinical hyperthyroidism (2.53%, 11/435), and thyroid cancer (1.84%, 8/435). The detection rates of thyroid diseases in urban and rural areas were 21.18% (295/1 393) and 11.14% (140/1 257), respectively. The detection rates of thyroid diseases in males and females were 11.42% (155/1 357) and 21.66% (280/1 293), respectively. The detection rates of thyroid diseases in 18-< 30, 30-< 40, 40-< 50, 50-< 60 and &ge;60 years old were 13.46% (91/676), 14.81% (81/547), 15.42% (89/577), 20.94% (85/406) and 20.05% (89/444), respectively. There were statistically significant differences between different areas, gender and age groups (χ 2 = 48.54, 50.53, 14.68, P < 0.05). Conclusions:The detection rate of subclinical hypothyroidism in adults in urban and rural areas of Hebei Province is relatively high, followed by Hashimoto's thyroiditis. Attention should be paid to the screening, evaluation, and intervention of thyroid function among urban female populations.

Objective:To investigate the value of SHOX2 and RASSF1A gene promoter region methylation detection for screening and diagnosis of early-stage lung adenocarcinoma.Methods:The mRNA sequencing data of 471 lung adenocarcinoma patients and corresponding methylation data of 413 cases were downloaded from The Cancer Genome Atlas (TCGA) database, the methylation levels of SHOX2 and RASSF1A gene promoter regions were calculated, and the difference in methy lation level between normal lung tissues and tumor tissues was analyzed. The clinical data of 54 patients with early-stage lung adenocarcinoma and 31 patients with benign lung tumors who underwent surgery at Drum Tower Hospital Affiliated to Nanjing University Medical School from January 2018 to January 2019 were retrospectively analyzed. The methylation status of SHOX2 and RASSF1A in tumor tissues and normal lung tissues (>5 cm from the edge of the tumor foci) (called clinical samples) was detect, and a positive methylation in the promoter region of either gene was considered as a combination of two genes methylation positivity. Using pathological diagnosis as the gold standard, the efficacy of gene methylation positivity in diagnosing early-stage lung adenocarcinoma was analyzed by receiver operating characteristic (ROC) curve. Patients with >80% of tumor cells in paraffin samples were screened, and mRNA high-throughput sequencing was performed in their tumor tissues and normal lung tissues. The relationship between positive methylation of the two genes and clinicopathological features was analyzed, and the correlation between the promoter region methylation level of the two genes and mRNA expression levels in clinical samples and TCGA database samples was analyzed by Spearman method. Gene set variance analysis (GSVA) method was used to analyze the differences in Kyoto Encyclopedia of Genes and Genomes enrichment pathways between two-gene methylation-positive clinical lung adenocarcinoma samples and corresponding methylation-negative lung adenocarcinoma.Results:In TCGA database, the SHOX2 promoter region methylation island contained 6 sequenced methylation sites, of which sites cg04532033 and cg01557547 methylation levels were higher in lung adenocarcinoma tissues than in normal lung tissues (both P < 0.05); the RASSF1A gene promoter region methylation island contained 11 sequenced methylation sites, and the methylation levels of 6 of these sites in lung adenocarcinoma tissues were higher than those in normal lung tissues (all P < 0.05). Compared with normal lung tissues, the methylation level of SHOX2 promoter region was higher in stage Ⅰ and Ⅱ lung adenocarcinoma tissues (both P < 0.05); the methylation level of RASSF1A promoter region was higher in all stages of lung adenocarcinoma ( P < 0.001). Among 54 patients with early-stage lung adenocarcinoma, 28 were positive for SHOX2 promoter region methylation in tumor tissues, 21 were positive for RASSF1A promoter region methylation, and 40 were positive for combined methylation of both genes; 31 benign lung nodules were negative for SHOX2 and RASSF1A methylation. ROC curve analysis showed that the sensitivity of positive SHOX2 promoter region methylation for diagnosing early-stage lung adenocarcinoma was higher than that of RASSF1A promoter region methylation positivity (51.8% vs. 38.9%), and the area under the curve (AUC) for diagnosis by two-gene methylation positivity was larger than that for diagnosis by SHOX2 or RASSF1A gene methylation positivity alone (0.870 vs. 0.759 and 0.694). The circulating thresholds (Ct) of SHOX2 and RASSF1A methylation tested by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) in stage Ⅰ and Ⅱ lung adenocarcinoma were lower than those in normal lung tissues (all P < 0.05); patients with two-gene methylation positivity were characterized by older age, longer tumor longest diameter and more advanced pathological stage compared with patients with two-gene methylation negativity (all P < 0.05). In clinical stage Ⅰ-Ⅱ lung adenocarcinoma samples, the Ct of SHOX2 and RASSF1A promoter region methylation tested by qRT-PCR was negatively correlated with their mRNA relative expression levels ( r=-0.43, P = 0.003; r = -0.48, P = 0.001); in TCGA database stage Ⅰ-Ⅱ lung adenocarcinoma samples, the level of SHOX2 promoter region methylation was negatively correlated with its mRNA relative expression level ( r = -0.23, P < 0.001), and the level of RASSF1A promoter region methylation was also negatively correlated with its mRNA relative expression level, but without statistical difference ( r = -0.05, P = 0.310). In two-gene promoter methylation-positive lung adenocarcinoma samples, the pathways related to folate metabolism and DNA stability were upregulated, and the pathways related to vasoconstriction and cell growth and differentiation were downregulated. Conclusions:The combined detection of SHOX2 and RASSF1A promoter region methylation can be used as an indicator for screening and diagnosis of early-stage lung adenocarcinoma. Abnormal promoter region methylation of the two genes may affect multiple tumor-related pathways and promote the occurrence and progression of early-stage lung adenocarcinoma.

Objective To investigate the inhibitory effect of ursolic acid in Hippophae rhamnoides L. on hepatocyte apoptosis in rats with alcoholic liver disease based on the mitochondria-cytochrome c pathway. Methods A total of 50 specific pathogen-free male Wistar rats were divided into normal control group, alcohol model group, and low-, middle-, and high-dose ursolic acid groups using a random number table, with 10 rats in each group. The rats in the normal control group were given normal saline by gavage once a day for 8 weeks; the rats in the alcohol model group were given alcohol at increasing concentrations by gavage for 8 consecutive weeks; the rats in the low-, middle-, and high-dose ursolic acid groups were given ursolic acid at a dose of 50, 100, and 150 mg/kg, respectively, followed by an equal volume of alcohol as the model group 1 hour later. Serum liver function parameters were measured for each group; HE staining was used to observe liver histopathology; an electron microscope was used to observe hepatocyte ultrastructure; the TUNEL method was used to measure hepatocyte apoptosis; Western Blotting was used to measure the protein expression levels of cytochrome c and activated caspase-3 in hepatocyte mitochondria and cytoplasm. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results Compared with the alcohol model group, the middle- and high-dose ursolic acid groups had significant reductions in the serum level of alanine aminotransferase, aspartate aminotransferase, and cholinesterase (all P < 0.05). The rats in the alcohol model group had disordered arrangement of hepatic cords with marked hepatocyte edema and fatty degeneration, while those in the middle- and high- dose ursolic acid groups had basically normal arrangement of hepatic cords and a significant improvement in hepatocyte fatty degeneration, as well as a significant increase in the number of hepatocyte mitochondria and a significant improvement in morphology. Compared with the alcohol model group, the middle- and high-dose ursolic acid groups had significantly lower hepatocyte apoptosis rate and protein expression levels of cytochrome c and caspase-3 in cytoplasm (all P < 0.05). Conclusion Ursolic acid in Hippophae rhamnoides L. can improve the liver function and histomorphology of rats with alcoholic liver disease, possibly by inhibiting the release of cytochrome c in hepatocyte mitochondria, the activation of caspase-3, and the apoptosis of hepatocytes via the mitochondria-cytochrome c pathway.

Acute intermittent porphyria (AIP) is a rare disease caused by autosomal dominant inheritance caused by mutations in PDGD/ HMBS gene. Clinical manifestations include severe abdominal pain, intestinal paralysis, limb weakness, epilepsy and psycho-emotional abnormalities. Due to the rarity of the disease and insufficient awareness of medical staff, the rate of clinical misdiagnosis is extremely high. Psycho-emotional abnormality is an important clinical manifestation of AIP and a common cause of acute attacks, but the current clinical attention is far from enough. This article reviews the current situation of anxiety, depression and other psycho-emotional abnormalities, quality of life, pain, fatigue, sleep, fear of disease progression, disease stigma, psychological pain and other indicators of AIP patients, in order to provide directions for improving domestic medical staff's medical care for AIP patients and to provide a basis for preventing attacks, reducing complications and improving prognosis.

Early childhood caries (ECC) is a significant chronic disease of childhood and a rising public health burden worldwide. ECC may cause a higher risk of new caries lesions in both primary and permanent dentition, affecting lifelong oral health. The occurrence of ECC has been closely related to the core microbiome change in the oral cavity, which may be influenced by diet habits, oral health management, fluoride use, and dental manipulations. So, it is essential to improve parental oral health and awareness of health care, to establish a dental home at the early stage of childhood, and make an individualized caries management plan. Dental interventions according to the minimally invasive concept should be carried out to treat dental caries. This expert consensus mainly discusses the etiology of ECC, caries-risk assessment of children, prevention and treatment plan of ECC, aiming to achieve lifelong oral health.
