The fundamental principle of traditional Chinese medicine(TCM) is holism, and it is crucial for TCM to address the key issue of the "holistic view" of Chinese herbal medicine. While the overall regulatory effects of Chinese herbal medicine have been widely recognized, the holistic internal logic of individual ingredients of Chinese herbal medicines require further clarification. In order to comprehensively understand the mechanism of action of Chinese herbal medicine, this paper combined the holistic view of Chinese herbal medicine with differentiation thinking to explore the intrinsic logical relationships within Chinese herbal medicine. Starting from the perspective of the coexistence of multiple components in Chinese herbal medicine, this paper systematically examined the "self-consistent" phenomenon within single Chinese herbal medicine. This phenomenon refers to the consistent or opposing actions of various components in terms of their physical and chemical properties, pharmacokinetic effects, biological effects, flavors and properties, and TCM efficacy. The paper summarized various logical relationships of syndrome differentiation exhibited by the same Chinese herbal medicine, analyzed the underlying reasons, and focused on analyzing external factors affecting the "self-consistent" phenomenon in the efficacy of Chinese herbal medicine, aiming to better elucidate the theoretical basis of the pharmacological effects of Chinese herbal medicine, further enrich the scientific connotation of the holistic view of Chinese herbal medicine, and provide theoretical guidance for the preparation process, compatibility patterns, and formulation design of Chinese herbal medicine.

OBJECTIVE: This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province. METHODS: We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed. RESULTS: The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α ^3.7/αα (50.23%) and β ^IVS-II-654/β ^N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively. CONCLUSION Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

OBJECTIVE: To analyze the kinetic characteristics of lymphocyte subsets and myeloid-derived suppressor cell (MDSC) in patients who newly diagnosed intermediate- to high-risk aGVHD and treated with steroids-ruxolitinib as the first line therapy from a single-arm, open clinical trial (NCT04061876). METHODS: We prospectively observed the efficacy of 23 patients having intermediate- to high-risk aGVHD and treated with steroids-ruxolitinib as the first line therapy. The kinetic characteristics of lymphocyte subsets and MDSC were monitored, and then we compared them in steroids-ruxolitinib group (n=23), free-aGVHD group (n=20) and steroids group (n=23). RESULTS: Of the 23 patients, the CR rate was 78.26% (18/23) on day 28 after first-line treatment with steroids-ruxolitinib. On day 28 after treatment, patients had lower level of CD4⁺CD29⁺ T cells (P=0.08) than that of pre-treatment, whereas levels of other lymphocyte subsets in this study were higher than that of pre-treatment; CD4⁺CD29⁺ T cells in CR patients decreased, compared with refractory aGVHD patients. On day 28 of treatment, CD8⁺CD28^- T cells (P=0.03) significantly increased in patients with aGVHD than that in patients without aGVHD, so did CD8⁺CD28^- T / CD8⁺CD28⁺ T cell ratio (P=0.03). Compared with patients without aGVHD, patients with aGVHD had lower level of G-MDSC, especially on day 14 after allo-HSCT (P=0.04). Compared with pre-treatment, M-MDSC was higher in CR patients on day 3 and 7 post-treatment (P₃=0.01, P₇=0.03), e-MDSC was higher on day 28 post-treatment (P=0.01). Moreover, compared with CR patients, M-MDSC was lower in refractory aGVHD patients on day 3 post-treatment (P=0.01) and e-MDSC was lower on day 28 post-treatment (P=0.01). Compared with steroids group, MDSC in steroids-ruxolitinib group was higher, with the most significant difference in M-MDSC (P₃=0.0351; P₇=0.0142; P₁₄=0.0369). CONCLUSION We found that patients newly diagnosed intermediate- to high-risk aGVHD receiving first-line therapy with steroids-ruxolitinib achieved high response rate. Moreover, the novel first-line therapy has a small impact on the immune reconstitution of patients after allo-HSCT. Elevated MDSC might predict a better response in aGVHD patients receiving this novel first-line therapy. M-MDSC responded earlier to steroids-ruxolitinib than e-MDSC, G-MDSC.

OBJECTIVES: To investigate the relationship between the perpetrator's sex, victim's position and slashing location as well as anthropometric parameters on distance and space required for slashing, to provide the theoretical basis for the judgment of whether the crime scene was consistent with the criminal activity space. METHODS: The kinematics data of 12 male and 12 female subjects slashing the neck of standing and supine mannequins as well as the chest of the standing mannequins with a kitchen knife were obtained by using a 3D motion capture system. The relationship between the perpetrator's sex-victim's position, the perpetrator's sex-slashing location, and anthropometric parameters and the distance and space required for the slashing were analyzed by two-factor repeated measures ANOVA and Pearson correlation analysis respectively. RESULTS: Compared with slashing the neck of supine mannequins, the distance (L) and normalized L (l) of slashing the neck of standing mannequins were greater, while vertical distance (L_VR) and normalized L_VR (l_VR) of the knife side were smaller. Compared with slashing the neck of standing mannequins, the L and l slashing the chest of standing mannequins were greater, while L_VR and l_VR were smaller. Horizontal distance (L_HR) and normalized L_HR (l_HR) of the knife side in males were greater than that in females. Height and arm length were positively correlated with L, L_HR, and L_VR when striking the standing mannequins. CONCLUSIONS When slashing the neck of supine or standing victims, the slashing distance is shorter and the slashing height is greater. Furthermore, the distance and space required for slashing are correlate with anthropometric parameters.

Tumor angiogenesis provides adequate oxygen and nutrition for tumor development and supports tumor growth and metastasis. Stromal cell derived factor 1 (SDF-1) and its receptor C-X-C motif chemokine receptor 4 (CXCR4) in pancreatic cancer microenvironment are involved in tumor growth such as promoting tumor cell proliferation, migration, and angiogenesis. In this study, anti-CXCR4 nanobody (CXCR4 Nb) and anti-programmed cell death ligand 1 (PD-L1) &CXCR4 bispecific nanobody (PX4 BsNb) were expressed in Escherichia coli system and purified by nickel column affinity chromatography. We investigated the anti-angiogenesis activity and mechanism of CXCR4 Nb by in vivo and in vitro experiments. Ethical approval was obtained for collection of human peripheral blood mononuclear cell (hPBMC) samples from the Local Ethics Committee of Shanghai Jiao Tong University. All animal experiments were approved by the Animal Ethic Committee of Shanghai Jiao Tong University. The results showed that CXCR4 Nb at 0.1 μmol·L^-1 could effectively inhibit the proliferation and migration of human umbilical vein endothelial cells (HUVEC) promoted by pancreatic stellate cells in vitro. CXCR4 Nb and PX4 BsNb at 0.3 mg·kg^-1 obviously decreased tumor angiogenesis and inhibited the tumor growth in NOD/SCID mice, the inhibitory rates were 28.8% and 36.1%, respectively. CXCR4 Nb significantly inhibited tumor growth and angiogenesis with great safety, which provides support for application of CXCR4 Nb and anti-angiogenesis therapy of pancreatic cancer.

Objective: To analyze the clinical characteristics of Wilson's disease (WD) with onset of acute liver failure (ALF) in children. Methods: Clinical data of 19 children diagnosed with WD presented with ALF in Xi'an Children's Hospital from January 2016 to April 2021 were retrospectively analyzed, including general condition, clinical manifestation, laboratory examination, and gene detection. The children were divided into the death group and survival group according to the clinical outcome. The children who had hepatic WD with non-ALF onset during the same period were selected as the control. The general conditions and laboratory indexes were compared between death group and survival group, ALF group and non-ALF group. T-test, Mann Whitney U test or χ² test were used to compare the differences between the two groups. Results: Of the 19 WD children with ALF onset, 10 were females and 9 were males. The age of admission was (10.1±2.6) years and time to onset of first visit was 9 (4, 15) days. Among the WD children with ALF onset, 4 children were lost to follow-up, 5 cases death (death group) and 10 cases survived (survival group). The ceruloplasmin in the death group was higher than that in the survival group (0.078 (0.055, 0.105) vs. 0.033 (0.027, 0.058) g/L, Z=-2.33, P=0.020). There were 95 children who had hepatic WD with non-ALF onset. The WD patients with ALF onset were older at admission (9.9 (8.0, 11.1) vs. 5.4 (3.7, 6.9) years, Z=-5.25, P<0.001), had higher ceruloplasmin (0.060 (0.030, 0.078) vs. 0.024 (0.006, 0.060) g/L, Z=-3.11, P=0.002), 24 h urinary copper (674 (205, 1 803) vs. 149 (108, 206) μg, Z=-4.25, P<0.001), and positive rate of K-F ring [17/19 vs. 7%(7/95), χ²=50.17, P<0.001] while shorter onset time at initial visit (0.3 (0.1, 0.5) vs. 1.0 (0.7, 6.0) months, Z=-4.28, P<0.001). There was no gender difference between the two groups [9/19 vs. 61%(58/95), χ²=1.22, P=0.269]. Of the 19 WD children with ALF onset, 13 had the ATP7B gene tested, and 15 reported variants were detected. The main variations were c.2333G>T (p. Arg778Leu), c.2621C>T (p. Ala874Val) and c.2975C>T (p. Pro992Leu). The allele frequencies were 6/26(23%), 4/26(15%) and 3/26(12%), respectively. Conclusions: Children of WD onset with ALF are school-aged and above. They have an acute onset, a short course of the disease, and poor prognosis. The positive rate of K-F ring, ceruloplasmin and urinary copper are higher than those of the hepatic WD children with non-ALF onset.

Objective: To observe the clinical efficacy of Tuina (Chinese therapeutic massage) manipulation for pediatric adenoid hypertrophy (AH). Methods: A total of 60 children with AH were randomized into an observation group and a medication group, with 30 cases in each group. The observation group was treated with pediatric Tuina treatment, and the medication group was treated with 0.05％ mometasone furoate nasal spray. The changes of main clinical symptom score, quality of life (QOL) score and X-ray nasopharynx lateral film were observed, and the clinical efficacy was evaluated. Results: The total effective rate of the observation group was 90.0％, and that of the medication group was 66.7％. The difference between the two groups was statistically significant (P<0.05). After treatment, the A/N value [ratio of adenoid thickness (A) and nasopharyngeal cavity width (N)] of posterior nasopharyngeal lateral film did not show significant change in either group (P>0.05). After treatment, the clinical symptom scores in both groups decreased, and the intra-group differences were statistically significant (P<0.001), but there was no statistical difference between the two groups (P>0.05). After treatment, the QOL scores of children in both groups decreased, and the intra-group differences were statistically significant (P<0.001), and the difference between the two groups was statistically significant (P<0.001). Conclusion: Tuina manipulation is effective in treating pediatric AH, and produces a better effect in improving traditional Chinese medicine symptoms and QOL than 0.05％ mometasone furoate nasal spray.

OBJECTIVE: To observe the effect of San-Ao Decoction (, SAD) on water metabolism of bronchial asthra model mice. METHODS: Forty-five female BALB/c mice were randomly divided into control, model and SAD groups by a random number table, 15 mice in each group. A composite method with ovalbumin (OVA) sensitization and challenge was developed to establish bronchial asthma model. Mice in the control group were intraperitoneally injected with distilled water without aerosol inhalation challenge. On day 15-22, 0.3 mL SAD was administered via gastric route in SAD group, one time per day, while an equivalent volume of normal saline was used for gastric administration in the control and model groups. Changes in airway resistance in the inspiratory phase (RI-R-Area) were detected using an AniRes2005 system, and 5-h urine output was collected by metabolic cages. Histopathological changes in lung and kidney were observed by hematoxylin-eosin staining. mRNA expressions of aquaporin (AQP) 1 and AQP2 in kidney were detected by reverse transcription-polymerase chain reaction, and the protein expressions of AQP1 and AQP2 in kidney were detected by immunohistochemistry. Enzyme-linked immune sorbent assay was used to detect the OVA-specific endothelium-1 (ET-1), antidiuretic hormone (ADH), atrial natriuretic peptide (ANP), prostaglandin E RESULTS: Compared with the control group, the serum IgE level in model group increased (P<0.01). Following the pathologic changes in lung tissue, no significant change in kidney tissue was observed among 3 groups. Compared with the control group, the mice in the model group showed elevated airway resistance during inhalation phase, higher mRNA and protein expression levels on AQP1 and AQP2 in kidney tissue and higher ET-1 levels in serum, lung and kidney tissues, ADH and ANP in lung and serum, PGE CONCLUSION San-Ao Decoction can regulate the urine volume through regulating AQP1 and AQP2 expression, and the expression of these in the kidneys might be regulated by ET-1, NO and Ang II.

BACKGROUND: Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread throughout the world. In this study, we aimed to identify the risk factors for severe COVID-19 to improve treatment guidelines. METHODS: A multicenter, cross-sectional study was conducted on 313 patients hospitalized with COVID-19. Patients were classified into two groups based on disease severity (nonsevere and severe) according to initial clinical presentation. Laboratory test results and epidemiological and clinical characteristics were analyzed using descriptive statistics. Univariate and multivariate logistic regression models were used to detect potential risk factors associated with severe COVID-19. RESULTS: A total of 289 patients (197 nonsevere and 92 severe cases) with a median age of 45.0 (33.0, 61.0) years were included in this study, and 53.3% (154/289) were male. Fever (192/286, 67.1%) and cough (170/289, 58.8%) were commonly observed, followed by sore throat (49/289, 17.0%). Multivariate logistic regression analysis suggested that patients who were aged ≥ 65 years (OR: 2.725, 95% confidence interval [CI]: 1.317-5.636; P = 0.007), were male (OR: 1.878, 95% CI: 1.002-3.520, P = 0.049), had comorbid diabetes (OR: 3.314, 95% CI: 1.126-9.758, P = 0.030), cough (OR: 3.427, 95% CI: 1.752-6.706, P < 0.001), and/or diarrhea (OR: 2.629, 95% CI: 1.109-6.231, P = 0.028) on admission had a higher risk of severe disease. Moreover, stratification analysis indicated that male patients with diabetes were more likely to have severe COVID-19 (71.4% vs. 28.6%, χ2 = 8.183, P = 0.004). CONCLUSIONS The clinical characteristics of those with severe and nonsevere COVID-19 were significantly different. The elderly, male patients with COVID-19, diabetes, and presenting with cough and/or diarrhea on admission may require close monitoring to prevent deterioration.
