Objective To explore the five-circuit and six-qi features of birth time and onset time of children with acute lymphoblastic leukemia(ALL).Methods A total of 877 cases of children with ALL from Children's Hospital of Soochow University from June 2021 to February 2023 were collected,and their five-circuit and six-qi features of birth time and onset time were analyzed.And then the correlation of five-circuit and six-qi features of birth time and onset time with ALL was explored preliminarily,and the pathogenic characteristics of congenital factors and acquired pathogenic factors were revealed.Results(1)The children who were born in the year with the heavenly stems being bing(the 3rd of the ten heavenly stems)and ding(the 4th of the ten heavenly stems)and with the earthly branches being shen(the 8th of the twelve earthly branches)and you(the 9th of the twelve earthly branches)are prone to suffer from ALL,and the birth year of children with ALL had the five-circuit and six-qi features of the joining of guest circuit with dominant circuit being rebellious.ALL is commonly seen in the year with the heavenly stems being geng(the 7th of the ten heavenly stems)and xin(the 8th of the ten heavenly stems)and with the earthly branches being zi(the 1st of the twelve earthly branches)and chou(the 2nd of the twelve earthly branches),and the onset year of ALL in children had the five-circuit and six-qi features of the yearly circuit being gold-circuit and water-circuit,sitian-zaiquan yearly circuit qi being shaoyin monarch-fire with yangming dryness-gold,taiyin damp-earth with taiyang cold-water,and the qi-circuit assimilation relationship being celestial correspondence,same celestial correspondence,celestial correspondence in convergent year,disharmony,mildly-rebellious,and celestial restriction.Conclusion Gold-dryness and water-cold are the congenital factors and acquired pathogenic factors of ALL.The onset of ALL in children is closely related to qi insufficiency and qi stagnation of wood and fire in five-circuit and six-qi theory.

Yigongsan， derived from QIAN Yi’s Key to Therapeutics of Children’s Diseases in the Song Dynasty， is a classic pediatric prescription that is included in the Catalogue of Ancient Classic Prescriptions （the Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine in 2022. This paper verifies and analyzes the historical origin， composition， dosage， processing， decoction method and efficacy of Yigongsan by systematically combing ancient books and modern documents. As a result， Yigongsan is composed of five herbs： Panax ginseng， Poria cocos， Atractylodes macrocephala， Citrus reticulata and Glycyrrhiza uralensis， of which P. cocos should be peeled， A. macrocephala is fried with soil， G. uralensis is roasted with honey while P. ginseng and C. reticulata are raw products. According to the dosage of ancient and modern times， each medicinal herb must be ground into fine powder， 1.6 g for each， added with 300 mL of water， 5 pieces of Zingiber officinale， and 2 Ziziphus jujuba， decocted together to 210 mL， and taken before meals. In ancient books， Yigongsan is used to treat vomiting， diarrhea， spleen and stomach deficiency， chest and abdominal distension， and lack of appetite， etc. Modern research showed that Yigongsan could also be used in the diseases of immune system， respiratory system， blood system， etc.， involving infantile anorexia， asthma， anemia， tumors and so on.

The use of tyrosine kinase inhibitors （TKI） has been an important advance in the systemic treatment of hepatocellular carcinoma， but their sustained anti-angiogenic therapy leads to increased tumor hypoxia， accelerates the development of a hypoxic microenvironment and promotes the expressions of hypoxia-inducible factors （HIF）， thereby inducing drug resistance of tumor patients to TKI. This paper summarizes the mechanism of action of HIF mediating TKI resistance in hepatocellular carcinoma in aspects of metabolic reprogramming， abnormal expressions of cancer and cancer-associated genes， and ferroptosis， and sorts resistance response strategies to provide reference for clinical solutions to TKI resistance issues. As results show， HIF/ glycolysis axis inhibitors （isoflavonoid genistein， simvastatin， etc.） can improve TKI resistance based on metabolic reprogramming mechanism； oncogene-targeted inhibitors combined with TKI （the combination of capsaicin and sorafenib） can improve TKI resistance based on abnormal expression of cancer and cancer-related genes； fatty acid synthase inhibitor （orlistat） can improve TKI resistance based on ferroptosis mechanism.

Lung cancer is the fastest-growing cancer type in terms of incidence and mortality worldwide， posing a huge threat to the health and life of the population. Radiation therapy is one of the main methods for treating lung cancer， and there is a clear dose-effect relationship between the radiation dose and local control rate of lung cancer. However， the lung is a radiation dose-limiting organ， and the radiation resistance of lung cancer tissues and the radiation damage to normal tissues limit the radiation efficacy for lung cancer. The pathogenesis of lung cancer in traditional Chinese medicine （TCM） is characterized by an initial deficiency in vital Qi， followed by the internal invasion and gradual accumulation of pathogenic Qi. After radiation therapy for lung cancer， the body's vital Qi becomes weaker， and syndromes of phlegm coagulation， Qi stagnation， and static blood blocking collaterals become more severe， leading to radiation resistance of lung cancer tissues. Therefore， the key issue to better clinical efficacy of radiation therapy for lung cancer patients is to use drugs to enhance the radiation sensitivity of lung cancer cells and improve the radiation tolerance of normal lung tissues. TCM can be used as a radiation sensitizer by regulating the cell cycle to increase the proportion of cells in the radiation-sensitive phase， promoting upregulation of pro-apoptotic genes and downregulation of anti-apoptotic genes to induce cell apoptosis， enhancing DNA damage caused by radiation and inhibiting damage repair， improving blood circulation and tissue oxygen supply， and so on， to enhance the sensitivity of tumor cells to radiation and amplify the toxicity of radiation to tumor tissues. TCM can also be used as a radiation protector by inhibiting cell damage， regulating cytokines and immune balance， reducing the release of inflammatory and fibrotic factors， and inhibiting the activation of related signaling pathways to prevent and treat radiation-induced lung injury. This article systematically reviewed the research results of TCM on radiation sensitization and radiation protection in lung cancer in recent years， aiming to elucidate the mechanism of TCM in regulating the effect of radiation therapy for lung cancer and provide more theoretical and practical basis for TCM to participate in improving the prognosis of lung cancer patients undergoing radiation therapy.

Objective:To compare the impact of orthodontic treatment on pulp volume in adolescents and adults.Methods:Cone-beam CT data of 62 patients undergoing orthodontic treatment at the Department of Orthodontics, Stomatological Hospital of Chongqing Medical University, from January 2019 to March 2022 were collected. Patients were divided into two age groups (31 patients in each group): adolescent group (aged 13-17, 17 males and 14 females) and adult group (aged 21-25, 12 males and 19 females). Pre-and post-treatment reconstructions of the pulp and dental tissues of upper first molars (UM1) and lower central incisors (L1) were performed. Measurements included pulp volume for UM1 (UM1 P) and L1 (L1 P), pulp chamber volume (UM1 PC) and root canal volume (UM1 RC) for UM1, root length for L1 (L1 RL), and mesiobuccal root length for UM1 (UM1 RL), as well as chamber heights at specific landmarks [the lengths from the central fossa fusion site to the roof of the pulp chamber (H1), the floor of the pulp chamber (H2), the nearest point of root divergence as well as crown-root bifurcation (H3), the farthest point of root divergence (H4), and the pulp chamber height (H5)] in UM1. Changes in these indices were calculated and analyzed using paired and independent sample t-tests for within-group and between-group differences, respectively. Pearson correlation was used to assess potential associations among H5, root length, and pulp volume changes. Results:Before and after orthodontic treatment, no significant difference was observed in the adult group for L1 P ( t=-0.03, P=0.975), while significant differences were noted for UM1 P, UM1 PC, and UM1 RC ( t=9.98, P<0.001; t=9.04, P<0.001; t=6.69, P<0.001). In the adolescent group, significant differences were found for both L1 P and UM1 P ( t=2.25, P=0.029; t=6.30, P<0.001). After orthodontic treatment, the absolute value changes of UM1 P, UM1 PC, and L1 P in the adolescent group were (19.75±9.58), (15.07±7.65) and (1.89±6.29) mm 3, respectively, and in the adult group were (13.33±9.41), (9.16±7.05) and (0.02±4.66) mm 3, respectively ( t=3.77, P<0.001; t=4.48, P<0.001; t=2.34, P=0.048). There was no significant absolute difference in the amount of UM1 RC between the two groups after orthodontic treatment ( t=0.86, P=0.391). Before and after orthodontic treatment, the absolute value changes of L1 RL, H1 and H5 in the adolescent group were (0.54±0.41), (0.38±0.27) and (0.71±0.33) mm, respectively, and the absolute value changes in the adult group were (0.78±0.62), (0.26±0.20) and (0.57±0.28) mm, respectively ( t=-2.43, P=0.017; t=2.96, P=0.004; t=2.57, P=0.011). Whereas no significant differences were observed for UM1 RL, H2, H3, and H4 ( t=-0.85, P=0.400; t=0.43, P=0.669; t=-0.50, P=0.619; t=1.46, P=0.148). Additionally, significant correlations were found between changes in H5 and UM1 RL with UM1 P ( r=0.35, P<0.001; r=0.19, P=0.030), but not between Changes in L1 RL and L1 P ( r=0.11, P>0.05). Conclusions:The effect of orthodontic treatment on pulp volume in adolescents and adults were different.

Purpose To investigate the diagnostic value of 18F-FDOPA PET/CT imaging and semi-quantitative analysis platform for the diagnosis of Parkinson's disease(PD).Materials and Methods There were 27 healthy controls and 56 clinically diagnosed PD patients,including 33 early PD(Hoehn-Yahr class Ⅰ-Ⅱ)and 23 advanced PD(Hoehn-Yahr class Ⅲ-Ⅳ),underwent 18F-FDOPA PET imaging in Nanjing First Hospital,Nanjing Medical University were consecutively enrolled from January 2018 to December 2019.The striatal to occipital ratio(SORs)in radioactivity was calculated by HERMES BRASS platform,thereby completing the semi-quantitative analysis of the brain based on regions of interest and observing the asymmetry of the striatal subregions in early-stage PD and late-stage PD patients.Using artificial intelligence techniques to perform principal component analysis on the SORs of the striatal subregions in PD group and healthy control group,the degree of data aggregation and the distinguishability between groups were observed.Results The SORs was significantly reduced in the whole caudate,anterior,posterior putamen and striatum of advanced PD patients(t=9.02-11.72,P<0.000 1).The area under the curve was 0.952,0.973,0.995 and 0.982,respectively.Compared with the healthy control group,the loss of striatal asymmetry index(mean)in each subregion of the striatum in early PD group was caudate(7.61±5.50)%,anterior putamen(11.43±8.97)%,posterior putamen(17.17±11.63)%,and whole striatum(10.65±7.46)%,respectively.The uptake of 18F-FDOPA in the striatum of PD patients was significantly reduced,and the most obvious loss of early PD patients was contralateral posterior putamen,with a decrease of 34%.Conclusion The platform semi-quantitative analysis of 18F-FDOPA PET/CT images provides objective semi-quantitative values for early diagnosis and differential diagnosis of PD.Asymmetry in the striatum,especially in the putamen,may be an important parameter for early diagnosis of PD..

Objective:To compare the efficacy of maxillary distraction osteogenesis (DO) and Le FortⅠ osteotomy (LFⅠ) in patients with complex cleft lip and palate.Methods:A retrospective study was conducted, clinical data were collected involving patients with complex cleft lip and palate who required combined orthodontic and orthognathic treatment and were treated at the Stomatological Hospital of Chongqing Medical University from January 2015 to December 2022. Patients were divided into three groups based on the surgical method used for the maxilla: total maxillary distraction (TMD, group A), anterior maxillary distraction (AMD, group B), and Le Fort Ⅰ osteotomy (LFⅠ, group C). Cone-beam CT scans and lateral cephalograms were obtained preoperatively and at 3 months postoperatively. Three-dimensional reconstructions were performed using Mimics 21.0 and Dolphin Imaging 11.9 software to evaluate changes in craniofacial morphology and airway. Data analysis was conducted using SPSS 25.0. Intragroup comparisons before and after surgery were performed using the Wilcoxon rank sum test, and intergroup comparisons among the three groups were conducted using the Kruskal-Wallis H test. Results:A total of 15 patients were included, with 5 patients in each group. The cohort comprised 8 males and 7 females, aged between 15 and 21 years. There were no statistically significant differences in the distribution of gender, age, or cleft lip and palate classification among the three groups ( P>0.05). Postoperatively, all three groups showed improvement in maxillary hypoplasia. Compared to preoperative measurements, the angle formed by the points A (subspinale), N (nasion), and B (supramentale) (ANB angle) increased in all three groups (all P<0.05). The vertical distance from point A to the nasion perpendicular (A-Nperp) increased in groups A and B ( P<0.05 for both) but not in group C ( P>0.05). The area of the alveolar gap showed an increasing trend in all three groups ( P>0.05). The mandibular plane angle (FMA) decreased postoperatively in group B but showed an increasing trend in the other two groups, though the differences were not statistically significant ( P>0.05). Postoperative airway volume increased or showed an increasing trend in groups A ( P<0.05) and B ( P>0.05) but decreased in group C ( P>0.05). Intergroup comparisons showed significant differences in the angle formed by the sella (S), nasion (N), and point A (SNA angle) and the vertical distance from the anterior nasal spine to the coronal plane (ANS-CP) ( P<0.05). Group A had significantly larger SNA angles and ANS-CP values than group B, and the ANS-CP value in group A was significantly larger than in group C (all P<0.05). There were no other statistically significant differences among the groups ( P>0.05). Conclusion:For patients with severe maxillary hypoplasia due to complex cleft lip and palate, TMD can correct sagittal discrepancies between the upper and lower jaws, increase upper airway volume, but may potentially enlarge the alveolar gap area and increase vertical height of the maxilla. AMD result in less change in maxillary position compared to TMD and is mainly used for patients with severe maxillary dental crowding, needing increased arch length, having minor sagittal discrepancies, or with preexisting velopharyngeal dysfunction. LFⅠ result in changes in maxillary position similar to AMD but less than TMD, making it suitable for patients with moderate maxillary hypoplasia and mild maxillary dental crowding. The advantage of LFⅠ lies in its precise postoperative occlusal design and accurate three-dimensional movement of the jaw.

OBJECTIVE: To explore the genetic etiology and related factors in 1 065 women with spontaneous abortions. METHODS: All patients have presented at the Center of Prenatal Diagnosis of Nanjing Drum Tower Hospital from January 2018 to December 2021. Chorionic villi and fetal skin samples were collected, and the genomic DNA was assayed by chromosomal microarray analysis (CMA). For 10 couples with recurrent spontaneous abortions but normal CMA results for abortive tissues, non-in vitro fertilization-embryo transfer (IVF-ET) pregnancies and no previous history of live births and no structural abnormalities of the uterus, peripheral venous blood samples were collected. Genomic DNA was subjected to trio-whole exome sequencing (trio-WES). Candidate variants were verified by Sanger sequencing and bioinformatics analysis. Multifactorial unconditional logistic regression analysis was carried out to analyze the factors that may affect chromosomal abnormality in spontaneous abortions, such as the age of the couple, number of previous spontaneous abortions, IVF-ET pregnancy and history of live birth. The incidence of chromosomal aneuploidies in spontaneous abortions during the first trimester was compared in young or advanced-aged patients by chi-square test for liner trend. RESULTS: Among the 1 065 spontaneous abortion patients, 570 cases (53.5%) of chromosomal abnormalities were detected in spontaneous abortion tissues, which included 489 cases (45.9%) of chromosomal aneuploidies and 36 cases (3.4%) of pathogenic/likely pathogenic copy number variations (CNVs). Trio-WES results have revealed one homozygote variant and one compound heterozygote variants in two pedigrees, both of which were inherited from the parents. One likely pathogenic variant was detected in the patient from two pedigrees. Multifactorial unconditional Logistic regression analysis suggested that age of patient was an independent risk factor of chromosome abnormalities (OR = 1.122, 95%CI: 1.069-1.177, P < 0.001), the number of previous abortions and IVF-ET pregnancy were independent protective factors for chromosomal abnormalities (OR = 0.791, 0.648; 95%CI: 0.682-0.916, 0.500-0.840; P = 0.002, 0.001), whilst the age of husband and history of live birth were not (P > 0.05). The incidence of aneuploidies in the abortive tissues has decreased with the number of previous spontaneous abortions in young patients (χ² = 18.051, P < 0.001), but was not significantly correlated with the number of previous spontaneous abortions in advanced-aged patients with spontaneous abortions (P > 0.05). CONCLUSION Chromosomal aneuploidy is the main genetic factor for spontaneous abortion, though CNVs and genetic variants may also underlie its genetic etiology. The age of patients, number of previous abortions and IVF-ET pregnancy are closely associated with chromosome abnormalities in abortive tissues.
