Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

ObjectiveTo investigate the effects of foliar fertilizer of nano-calcium carbonate and calcium nitrate tetrahydrate on the agronomic traits， carbohydrate and endogenous hormone contents of Dendrobium officinale planted for 1 year under greenhouse cultivation， in order to provide scientific basis for fertilization to improve the yield and quality of D. officinale. MethodsSingle-factor experimental design was adopted. Starting from early spring， D. officinale was treated with foliar spraying according to corresponding fertilizers. Three treatment groups were established based on different fertilizers， namely， a blank group（clear water）， a nano-calcium carbonate group（0.727 g·L^-1 nano-calcium carbonate water-soluble fertilizer）， and a calcium nitrate tetrahydrate group（1.091 g·L^-1 calcium nitrate tetrahydrate water-soluble fertilizer）. The frequency of spraying was three times per month， and the entire treatment process lasted for nine months. The effects of various treatments on the traits and relative chlorophyll content of D. officinale were dynamically monitored. Sampling was conducted at three specific time points：August 2， 2023， September 8， 2023， and November 1， 2023， respectively. The contents of glucose and mannose in D. officinale stems were determined by high performance liquid chromatography（HPLC）， the content of soluble sugars in D. officinale stems and leaves was determined by phenol method， and enzyme-linked immunosorbent assay（ELISA） was used to detect the concentrations of cytokinin and auxin. ResultsCompared with the blank group， the treatments with nano-calcium carbonate and calcium nitrate tetrahydrate could significantly increase stem length， stem node number， leaf number， and tiller number. Among them， during the harvesting period in November， the stem length and tiller number， which are indicators related to the yield of D. officinale， increased by 60.85% and 19.23% after treatment with calcium nitrate tetrahydrate， and by 32.54% and 28.85% after treatment with nano-calcium carbonate， respectively. Compared with the blank group， treatments with nano-calcium carbonate and calcium nitrate tetrahydrate could promote the accumulation of sucrose in the stems and leaves of D. officinale to varying degrees， as well as the accumulation of polysaccharides， mannose， and glucose in the stems. In addition， nano-calcium carbonate treatment also facilitated the accumulation of fructose in the stems and leaves of D. officinale. Specifically， during the harvesting period in November， polysaccharides and mannose， which were the main active ingredients in D. officinale stems， increased by 28.48% and 29.36% after treatment with calcium nitrate tetrahydrate， and by 39.91% and 82.62% after treatment with nano-calcium carbonate， respectively. In addition， compared with the blank group， the concentrations of auxin in the stems and leaves of D. officinale were significantly increased after treatment with calcium nitrate tetrahydrate（P<0.05）. Similarly， the concentrations of cytokinin and auxin in the stems of D. officinale were also elevated after treatment with nano-calcium carbonate. Correlation analysis further indicated that elongation growth and tillering of D. officinale stems after foliar spraying of nano-calcium carbonate and calcium nitrate tetrahydrate might be related to the accumulation of carbohydrates in the stems and leaves and the synergistic effect of auxin and cytokinin. ConclusionIn production practice， spraying nano-calcium carbonate and calcium nitrate tetrahydrate can promote the accumulation of cytokinin， auxin， and carbohydrate contents in the stems and leaves of D. officinale， and promote tillering and elongation growth of the stems.

ObjectiveTo analyze the quantity-quality transfer of standard decoction of Ginseng Radix et Rhizoma（GRR） decoction pieces produced by fresh and traditional cutting， and to provide reference for quality control and application development of the decoction pieces produced by fresh cutting. MethodTen batches of representative GRR decoction pieces produced by fresh and traditional cutting and their standard decoctions were prepared by standard process， and high performance liquid chromatography（HPLC） fingerprint of the standard decoction was established and performed on an Agilent EC-C₁₈ column（4.6 mm×150 mm， 2.7 μm） with acetonitrile（A）-0.1% phosphoric acid aqueous solution（B） as the mobile phase for gradient elution（0-23 min， 18%-21%A； 23-35 min， 21%-28%A； 35-80 min， 28%-32%A）， and the detection wavelength was 203 nm. Then similarity evaluation， principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA） of fingerprint of the standard decoction were performed to screen the differential components with variable importance in the projection（VIP） value>1. Quantitative analysis was carried out on the screened known differential components， and combined with the indicators of the dry extract rate and the transfer rate， to explore the differences in the quantity-quality transfer between the standard decoction of GRR decoction pieces produced by fresh and traditional cutting. ResultThe fingerprint similarity of the standard decoction of GRR decoction pieces produced by fresh and traditional cutting was more than 0.950， and 18 common peaks were identified， including 9 identified common peaks. The results of PCA and PLS-DA showed that there were some differences in the contents of index components between the two standard decoctions. The contents of ginsenoside Rg₁， Re and Ro in GRR decoction pieces produced by fresh cutting were higher than those in traditional decoction pieces， while the contents of ginsenoside Rb₁， Rc ， Rb₂ and Rd were lower than those in traditional decoction pieces. The contents of ginsenoside Rg₁， Re， Rb₁ and Ro in the standard decoction of GRR decoction pieces produced by fresh cutting were higher than those in the standard decoction of traditional decoction pieces， while the contents of ginsenoside Rc ， Rb₂ and Rd were comparable between the two standard decoctions. Compared with the standard decoction of the traditional decoction pieces， the average transfer rates of ginsenoside Rg₁， Rb₁， Rc， Rb₂ and dry extract rate of the standard decoction of GRR decoction pieces produced by fresh cutting were significantly increased（P<0.05）， and the average transfer rate of ginsenoside Re and Rd also increased， but the difference was not statistically significant. ConclusionThe dry extract rate， content and transfer rate of index components of standard decoction of GRR decoction pieces produced by fresh cutting are better than those of the standard decoction of traditional decoction pieces， which can provides data support for the subsequent clinical application of fresh cutting products.

Ulcerative colitis （UC） is a chronic inflammatory bowel disease with complex etiology. The pathogenesis of this disease， due to a combination of factors， is complex and has not yet been elucidated. Among them， intestinal mucosal barrier damage is the basic pathological change of UC. As a non-destructive response of cells， autophagy regulates intestinal mucosal immunity， inflammation， oxidative stress， and bacterial homeostasis through degradation and reabsorption to actively repair damaged intestinal mucosal barrier， exerting a key role in the occurrence and development of UC. The disease is mainly treated clinically with aminosalicylic acid preparations， glucocorticoids， and immunosuppressants. Western medicine treatment of the disease has a fast onset of effect， and the short-term efficacy is definite， but the long-term application is easy to be accompanied by more adverse reactions. Moreover， some drugs are expensive， bringing great physical and mental pain and economic burden to patients. Therefore， it is urgent to explore new therapies with stable efficacy and mild adverse effects. In recent years， a large number of studies have shown that Chinese medicine can regulate autophagy of the intestinal mucosa with multiple targets and effects and repair the intestinal mucosal barrier function， thereby inhibiting the development of UC. Many experiments have shown that the active ingredient or monomers and compound formulas of Chinese medicine can improve the immunity of the intestinal mucosa， inflammation， oxidative stress， and flora by regulating the level of autophagy to maintain the normal function of the intestinal mucosal barrier to effectively intervene in UC， providing a new measure for the prevention and treatment of UC. However， there is a lack of systematic review of Chinese medicine in regulating the level of autophagy in the intestinal mucosa for the prevention and treatment of UC. Therefore， based on the current research on UC， autophagy process， and Chinese medicine treatment， this article reviewed the relationship of autophagy and its key target proteins with UC to clarify the key role of autophagy in UC production and systematically summarized Chinese medicines targeting the regulation of autophagy to treat UC in recent years to provide new ideas for the treatment and drug development of UC.

Objective:To explore the correlation between clinical classification and genotype and prognosis among Chinese children with Very-long chain acyl-CoA dehydrogenase deficiency (VLCADD).Methods:A Chinese pedigree affected with VLCADD admitted at the First People′s Hospital of Yunnan Province in February 2019 was selected as the study subject. The characteristics of disease onset, diagnosis and treatment and prognosis were retrospectively analyzed. Relevant literature was also systematically searched and reviewed.Results:The proband, a 1-year-old boy, had the clinical manifestations of frequently vomiting, hypoglycemia, abnormal liver function and myocardial enzymes. Tandem mass spectrometry screening showed significantly elevated C14, C14: 1, C16: 1, C16: 2, C18 and C14/C8. Genetic testing revealed that he has harbored compound heterozygous variants of the ACADVL gene, namely c. 664G>A (p.G222R) and c. 1345G>A (p.E449K), which were respectively derived from his father and mother. The child was diagnosed with VLCADD cardiomyopathy type and deceased 2 weeks later. Literature review has identified 60 Chinese children with VLCADD. The clinical classifications were mainly cardiomyopathy type and liver disease type, which accounted for 73.3% (43/60). The combination of ACADVL gene variants were correlated with the clinical classifications of VLCAD. Children with one or two loss-of-function (LOF) mutations showed more severe clinical manifestation and a higher mortality. Cardiomyopathy type had the poorest prognosis, with a mortality rate of 76.9% (20/26). C14: 1 may be used as an indicator for the diagnosis of VLCADD, but cannot be used for clinical subtyping and prognosis evaluation. The c. 1349G>A (p.R450H) variant had the highest frequency among the Chinese patients, accounting for 10.8% (13/120). Conclusion:The clinical classifications of VLCADD are strongly correlated with the prognosis, and LOF mutations are more common in those with severe clinical manifestations. c. 1349G>A (p.R450H) may be the most common variant among the Chinese patients, and early screening and diagnosis can greatly improve the prognosis of patients.

Objective To investigate the differences in treatment experience and quality of life between adolescent orthodontic pa-tients using clear aligners and fixed braces.Methods A total of 104 adolescent patients were selected who underwent orthodontic treat-ment with either clear aligners or fixed braces at Nanjing Medical University Affiliated Stomatological Hospital from January 2022 to June 2022.The patients were divided into two treatment groups based on the type of orthodontic appliance,with 52 patients in each group.Within a 6-month period of using clear aligners or fixed braces,adolescent orthodontic patients were surveyed using the child oral health impact profile-short form 19(COHIP-SF19)and other individual items.The differences in mean satisfaction,quality of life,and statistical scores were compared using independent samples t-tests,while the differences in subjective responses were compared using the Wilcoxon rank-sum test.Results There were no significant differences in mean quality of life and statistical scores between the two groups,but patients in the clear aligner group reported higher satisfaction.The clear aligner group reported greater difficulty with eating,while patients with fixed braces were more likely to experience negative emotions.Additionally,there were no significant differences between the two groups in terms of adaptation time to the appliance,maintaining dental hygiene,and feeling attractive.Conclusion Patients in both groups were generally satisfied with their treatment.Adolescent orthodontic patients treated with clear a-ligners or fixed braces for at least 6 months exhibit similar overall quality of life.

AIM:This study is aimed to investigate the impact of 3,5,6,7,8,3',4'-heptamethoxyflavone(HMF)on the proliferation,invasion,and migration of human colorectal cancer(CRC)cell lines(SW480 and HCT116)and preliminarily explore the underlying molecular mechanisms.METHODS:Human colorectal cancer cells(SW480 and HCT116)cultured in vitro were subjected to various concentrations of HMF(0,12.5,25 and 50 μmol/L)for 48 h.Proliferation levels were assessed using the CCK-8 assay,invasion abilities were examined via the Transwell assay,migra-tion rates were measured using the scratch assay,and oxidative stress levels were determined by the DCF-DA reactive oxy-genation assay.The mRNA expression levels of heme oxygenase-1(HO-1)mRNA and NAD(P)H:quinone oxidoreduc-tase-1(NQO-1)were quantified using RT-qPCR.RESULTS:Treatment with varying concentrations of HMF resulted in a significant reduction in the proliferative capacity of SW480 and HCT116 cancer cells,as was indicated by CCK-8 experi-ments(P<0.05).Transwell assays demonstrated a pronounced attenuation in the invasive potential of SW480 and HCT116 following HMF treatment(P<0.05).Scratch assays highlighted a notable constraint on the migratory capabilities of SW480 and HCT116 after HMF treatment(P<0.05).DCF-DA staining revealed a substantial increase in reactive oxy-gen species(ROS)levels within SW480 and HCT116 cells after HMF treatment(P<0.05).Furthermore,RT-qPCR ex-periments elucidated that HMF markedly suppressed the mRNA expression of antioxidant genes HO-1 and NQO-1.CON-CLUSION:HMF induces oxidative stress response in SW480 and HCT116 cells,consequently inhibiting their prolifera-tion,invasion and migration.

Objective To investigate the neuroprotective effect of Huangpu Tongqiao Capsule(HPTQ)in a rat model of Wilson disease(WD)and explore the underlying mechanisms.Methods SD rat models of WD were established by feeding of copper-supplemented chow diet and drinking water for 12 weeks,and starting from the 9th week,the rats were treated with low-,moderate-and high-dose HPTQ,penicillamine,or normal saline by gavage on a daily basis for 3 weeks.Copper levels in the liver and 24-h urine of the rats were detected,and their learning and memory abilities were evaluated using Morris water maze test.HE staining was used to observe morphological changes of CA1 region neurons in the hippocampus,and neuronal apoptosis was detected with TUNEL staining.Hippocampal expressions of endoplasmic reticulum stress(ERS)-mediated apoptosis pathway-related proteins GRP78,CHOP,caspase-12,cleaved caspase-9,and cleaved caspase-3 at both the mRNA and protein levels were detected using RT-qPCR,immunofluorescence assay or Western blotting.Results Compared with normal control rats,the rat models with copper overload-induced WD exhibited significantly increased copper levels in both the liver and 24-h urine,impaired learning and memory abilities,obvious hippocampal neuronal damage in the CA1 region and increased TUNEL-positive neurons(P<0.01),with also lowered mRNA and protein expressions of GRP78,CHOP,caspase-12,cleaved caspase-9,and cleaved caspase-3 in the hippocampus(all P<0.01).Treatments with HPTQ and penicillamine significantly lowered copper level in the liver but increased urinary copper level,improved learning and memory ability,alleviated neuronal damage and apoptosis in the hippocampus,and decreased hippocampal expressions of GRP78,CHOP,caspase-12,cleaved caspase-9,and cleaved caspase-3 in the rat models(P<0.01 or 0.05).Conclusion HPTQ Capsule has neuroprotective effects in rat models of WD possibly by inhibiting ERS-mediated apoptosis pathway.
