Chemotherapy based on cisplatin or its combination therapy is a common cancer treatment method. However， the non-specific side effects of cisplatin， poor pharmacokinetic properties of small molecule drugs， and susceptibility to drug resistance greatly limit the clinical application of cisplatin as first-line anti-tumor drug. With the development of nanocarrier technology， liposomes have become an ideal carrier for delivering cisplatin drugs due to their excellent properties of targeting， reducing toxicity， and enhancing efficacy. This paper reviews the status of cisplatin liposome both domestically and internationally which have entered clinical trials， including L-NDDP，SPI-077®， Lipoplatin®，LiPlaCis，SLIT and ILC， etc. Currently， only Lipoplatin® and ILC are showing good potential in cancer therapy. Although cisplatin liposome has made some progress in reducing systemic toxicity and improving treatment efficiency in clinical research， there is still potential for further improvement in tumor targeting and reducing side effects. In the future， more low-toxicity and efficient cisplatin liposomes can be developed through formulation technologies such as co-delivery liposome， stimuli-responsive liposome and targeting liposome.

ObjectiveTo investigate the preventive effect and mechanism of Dendrobium officinale （DO） on non-alcoholic fatty liver disease （NAFLD） by network pharmacology and animal experiments. MethodsDO components in blood after administration were identified and analyzed using ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry （UPLC-QE-HF-MS/MS）. Network pharmacology and molecular docking methods were employed to obtain active ingredients and potential targets of DO for NAFLD control. High-fat feeds were used to replicate the NAFLD rat model. Biochemical kits were used for detecting the expression levels of blood lipids， hepatic lipids， and liver functions of rats. Hematoxylin-eosin （HE） staining and oil red O staining were employed to observe pathological changes in rat liver， and real-time fluorescence quantitative PCR （Real-time PCR） assay was performed to validate potential targets obtained from the network pharmacology analysis. ResultsA total of 13 DO components were identified in blood， including berberine， dihydrosanguinarine， and oxypeucedanin. A total of 14 potential targets were screened through network pharmacology， including Forkhead box protein O1 （FoxO1）， epidermal growth factor receptor （EGFR）， and insulin-like growth factor 1 （IGF-1R）， involving pathways such as the advanced glycation end product （AGE）/receptor for AGE （RAGE） signaling pathway， blood lipids and atherosclerosis， insulin resistance， and FoxO signaling. The results of animal experiments showed that the NAFLD rat model was successfully replicated. After the preventive treatment with DO for NAFLD rats， the indexes of blood lipids， hepatic lipids， and liver function were normalized； lipid deposition and lesions in the liver were significantly improved； the expression level of FoxO1 mRNA in the liver was significantly reduced （P<0.05）， and the mRNA expression levels of phosphatidylinositide 3-kinases （PI3K）， protein kinase B （Akt）， EGFR， and IGF-1R were significantly increased （P<0.05）. ConclusionDO has a preventive effect on NAFLD rats， and the mechanism of action may be related to the modulation of IGF1R and EGFR targets and activation of the PI3K/Akt/FoxO1 signaling pathway.

Investigator initiated trial （IIT） represents a primary format for clinical research in traditional Chinese medicine （TCM）. As key implementation sites for TCM-based IIT targeting malignant tumors， western medicine institutions often face unique challenges in conducting such studies， which limit their feasibility and standardization. This paper reviews the registration status of TCM-based IIT for malignancies conducted in western medical institutions and analyzes key difficulties， including complex project initiation and management processes， limited TCM knowledge and skills among western medicine physicians， and relatively low patient acceptance of TCM. From a practical perspective， the study proposes several optimization strategies. These include improving the review and management mechanisms of TCM-related IIT within western medical institutions， establishing multidisciplinary clinical research teams that integrate TCM and western medicine， and enhancing investigators' training in TCM theory and clinical skills. Additionally， the study suggests standardizing IIT operational procedures， objectifying the collection of TCM diagnostic information， refining subject recruitment methods， and increasing TCM involvement in patient follow-up and management. These investigator-oriented， TCM-featured， and operable strategies aim to promote the high-quality development of TCM-based IIT in western medicine institutions and enhance the clinical application of TCM.

This paper introduces the academic characteristics of Professor ZHANG Ren in treatment with acupuncture for refractory eye diseases in modern times, guided by "homotherapy for heteropathy" (same therapy for different diseases sharing the same pathogenesis). The refractory eye diseases in modern times include a variety of conditions such as glaucoma, macular degeneration, diabetic retinopathy, high myopia and its complications, dry eye, cortical visual impairment and genetic eye diseases. The same therapy is used because these diseases share the similar location and pathogenesis. Professor ZHANG optimizes the methods of acupoint selection and provides the comprehensive prescriptions, "basic prescription, prescription based on disease differentiation, and supplementary prescription". A variety of acupuncture manipulation techniques are operated in clinical practice, such as compound needling methods, penetration needling, manipulations for promoting qi movement and conducting qi flow. "Early, regular and persistent" treatment is the common requirement with "the same acupoints, the same prescription and the same acupuncture method" as well as at "the same time". It is also proposed that the treatment should be provided flexibly according to the different symptoms, "identifying the differences within similarities".

OBJECTIVE: To analyze RELT gene mutation found in a pedigree with clinical features and inheritable pattern consistent with amelogenesis imperfecta (AI) in China, and to study the relationship between its genotype and phenotype. METHODS: Clinical and radiological features were recorded for the affected individuals. Peripheral venous blood samples of the patient and family members were collected for further study, and the genomic DNA was extracted to identify the pathogenic gene. Whole exome sequencing (WES) was performed to analyze the possible pathogenic genes, and Sanger sequencing was performed for validation. SIFT and PolyPhen-2 were used to predict and analyze the mutation effect. Comparison of RELT amino acids across different species were performed by using Uniprot website. In addition, the three-dimen-sional structures of the wild type and mutant proteins were predicted by Alphafold 2. RESULTS: The proband exhibited typical hypocalcified AI, with heavy wear, soft enamel, rough and discolored surface, and partial enamel loss, while his parents didn ' t have similar manifestations. WES and Sanger sequencing results indicated that the proband carries a homozygous frameshift mutation in RELT gene, NM_032871.3: c.1169_1170del, and both of his parents were carriers. This mutation was predicted to be pathogenic by SIFT and PolyPhen-2. Up to now, there were 11 mutation sites in RELT gene were reported to be associated with AI, and all of the patients exhibited with hypocalcified AI. Compared with the wild-type RELT protein, the mutant protein p. Pro390fs35 conformation terminated prematurely, affecting the normal function of the protein. CONCLUSION Through phenotype analysis, gene sequencing, and functional prediction of a Chinese family with typical amelogenesis imperfecta, this study found that RELT gene frameshift mutation can lead to protein dysfunction in AI patients. Further research will focus on the role and mechanism of RELT in enamel development at the molecular and animal levels, providing molecular biology evidence for the genetic counseling, prenatal diagnosis, and early prevention and treatment of AI.

Objective:To investigate the clinicopathological features and molecular characteristics of β-catenin-deficient colorectal cancer.Methods:The clinical, pathological and molecular features of 11 colorectal cancers with β-catenin protein loss diagnosed at the 960th Hospital of People′s Liberation Army of China, from January 2012 to November 2022 were analyzed.Results:Among the 11 patients, 3 were males and 8 were females. Their age ranged from 43 to 74 years, with the median age of 59 years. Six were in the left colon and 5 were in the right colon. One of the 11 cases had lymph node metastasis, 10 cases were well and moderately differentiated adenocarcinoma, and 1 was mucinous adenocarcinoma. Eight cases were of TNM stage T4, 2 of T1 stage and 1 of Tis stage. β-catenin protein was not detected using immunohistochemistry. Sanger sequencing revealed the presence of fragment-deletion mutation in exon 3 of CTNNB1 gene, resulting in loss of β-catenin protein expression.Conclusion:β-catenin deficiency is present in a small number of colorectal cancers and may be associated with exon 3 mutations of CTNNB1 gene.

ObjectiveTo investigate the role and possible mechanism of action of rhubarb decoction （RD） retention enema in improving inflammatory damage of brain tissue in a rat model of mild hepatic encephalopathy （MHE）. MethodsA total of 60 male Sprague-Dawley rats were divided into blank group （CON group with 6 rats） and chronic liver cirrhosis modeling group with 54 rats using the complete randomization method. After 12 weeks， 40 rats with successful modeling which were confirmed to meet the requirements for MHE model by the Morris water maze test were randomly divided into model group （MOD group）， lactulose group （LT group）， low-dose RD group （RD1 group）， middle-dose RD group （RD2 group）， and high-dose RD group （RD3 group）， with 8 rats in each group. The rats in the CON group and the MOD group were given retention enema with 2 mL of normal saline once a day； the rats in the LT group were given retention enema with 2 mL of lactulose at a dose of 22.5% once a day； the rats in the RD1， RD2， and RD3 groups were given retention enema with 2 mL RD at a dose of 2.5， 5.0， and 7.5 g/kg， respectively， once a day. After 10 days of treatment， the Morris water maze test was performed to analyze the spatial learning and memory abilities of rats. The rats were analyzed from the following aspects： behavioral status； the serum levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） and the level of blood ammonia； pathological changes of liver tissue and brain tissue； the mRNA and protein expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （AKT）， and mammalian target of rapamycin （mTOR） in brain tissue. 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. ResultsCompared with the MOD group， the RD1， RD2， and RD3 groups had a significantly shorter escape latency （all P<0.01）， significant reductions in the levels of ALT， AST， IL-1β， IL-6， TNF-α， and blood ammonia （all P<0.05）， significant alleviation of the degeneration， necrosis， and inflammation of hepatocytes and brain cells， and significant reductions in the mRNA and protein expression levels of PI3K， AKT， and mTOR in brain tissue （all P<0.05）， and the RD3 group had a better treatment outcome than the RD1 and RD2 groups. ConclusionRetention enema with RD can improve cognitive function and inflammatory damage of brain tissue in MHE rats， possibly by regulating the PI3K/AKT/mTOR signaling pathway.

ObjectiveTo investigate the efficacy of percutaneous transhepatic variceal embolization （PTVE） alone or in combination with partial splenic embolization （PSE） in the treatment of portal hypertensive hemorrhage in liver cirrhosis through a meta-analysis. MethodsThis study was conducted according to PRISMA guideline， with a PROSPERO registration number of CRD42023396690. Wanfang Med Online， CNKI， CBM， VIP Databases， PubMed， Embase， the Cochrane Library， and Web of Science databases were searched for articles on PTVE alone or in combination with PSE in the treatment of portal hypertensive hemorrhage in liver cirrhosis published up to December 23， 2022. The articles were selected based on inclusion and exclusion criteria， and related data were extracted. The RevMan 5.4.1 statistical analysis software was used to perform the meta-analysis. ResultsEight articles were finally included， with a total sample size of 592 cases， among which there were 316 cases in the PTVE+PSE group and 276 cases in the PTVE group. The meta-analysis showed that compared with the PTVE group， the PTVE+PSE group had significantly lower postoperative portal vein pressure （standardized mean difference ［SMD］=-1.75， 95% confidence interval ［CI］： -2.33 to -1.16， P<0.05）， postoperative diameter of the portal vein （SMD=-0.87， 95%CI： -1.64 to -0.10， P<0.05）， postoperative rebleeding rate （odds ratio ［OR］=0.17， 95%CI： 0.11 — 0.28， P<0.05）， mortality rate （OR=0.13， 95%CI： 0.04 — 0.37， P<0.05）， and incidence rate of postoperative portal hypertensive gastrointestinal disease （OR=0.17， 95%CI： 0.07 — 0.45， P<0.05］， as well as a significantly higher postoperative platelet level （SMD=0.79， 95%CI： 0.52 — 1.06， P<0.05）， while there were no significant differences between the two groups in the incidence rates of postoperative ascites. ConclusionCompared with PTVE alone， PTVE combined with PSE can effectively reduce the rebleeding rate and mortality rate of portal hypertensive hemorrhage in liver cirrhosis， the incidence rate of portal hypertensive gastrointestinal disease， and portal vein pressure， and it can also shorten the diameter of the portal vein and increase platelet level. Therefore， it is an effective interventional method for the treatment of portal hypertension hemorrhage in liver cirrhosis.

ObjectiveTo investigate the attenuating effect of Dioscoreae Bulbiferae Rhizoma（DBR） processed with Phaseoli Radiati Semen（PRS） juice， and explore the attenuating mechanism based on ferroptosis of the main toxic target organ. MethodSixty male ICR mice were randomly divided into blank group， DBR group， water roasted DBR group（hereinafter referred to as water group）， PRS juice-roasted DBR group 1（DBR-PRS 10∶1， stuffy moistening for 40 min， stir-fried at 130 ℃ for 18 min， hereinafter referred to as group 1）， PRS juice-roasted DBR group 2（DBR-PRS 10∶1， stuffy moistening for 80 min， stir-fried at 100 ℃ for 14 min， hereinafter referred to as group 2）， PRS juice-roasted DBR group 3（DBR-PRS=20∶3， stuffy moistening for 40 min， stir-fried at 160 ℃ for 14 min， hereinafter referred to as group 3）. The raw and processed groups of DBR were gavaged with their corresponding 95% ethanol extract at a dose of 3 g·kg^-1·d^-1， while the blank group was gavaged with an equal volume of 0.5% sodium carboxymethyl cellulose， once a day for 14 consecutive days. Hematoxylin-eosin（HE） staining was used to observe the histopathological changes of mouse liver. Alanine aminotransferase（ALT） and aspartate aminotransferase（AST） levels in serum， as well as malondialdehyde（MDA）， ferrous ions（Fe²⁺）， reduced glutathione（GSH） and superoxide dismutase（SOD） levels in liver tissue were detected by the biochemical detection. Western blot was used to detect the expression of iron key proteins such as ferritin heavy chain 1（FTH1） and glutathione peroxidase 4（GPX4）. ResultHE staining results showed that the liver tissue structure of the blank group was clear， the morphology of hepatocytes was normal， the cytoplasms of hepatocytes in the DBR group and water group were loose and vacuolar， with obvious pathological damages， and the pathologic damages of mice in the group 1-3 were significantly improved. Compared with the blank group， the levels of ALT， AST， MDA and Fe²⁺ in mice from the DBR group were significantly increased（P<0.01）， while GSH and SOD levels were significantly reduced（P<0.01）， and the protein expression levels of FTH1 and GPX4 were significantly decreased（P<0.01）. Compared with the DBR group， the ALT， AST，MDA and Fe²⁺ levels of mice in the group 1-3 were significantly reduced（P<0.05， P<0.01）， the GSH and SOD levels and the protein expression levels of FTH1 and GPX4 were significantly increased（P<0.01）. Compared with the water group， the AST and MDA levels of mice in the group 1-3 were significantly reduced（P<0.05， P<0.01）， the SOD level significantly increased（P<0.05， P<0.01）， the FTH1 protein expression significantly increased（P<0.01）， and the serum ALT level of mice in the group 2-3 significantly reduce（P<0.01）， Fe²⁺ level significantly reduced（P<0.01）， GSH level significantly increased（P<0.05， P<0.01）， and GPX4 protein expression significantly increased（P<0.05， P<0.01）. Among the group 1-3， the group 3 had the best detoxification effect. ConclutionProcessing with PRS juice can reduce the liver injury induced by DBR， and the mechanism may be related to the inhibition of ferroptosis in the liver.

Objective:To confirm the potential etiological factors of congenital aortic stenosis(AS)by genetic analysis on prenatal diagnostic results of the fetus with AS.Methods:Amniocentesis for chromosomal G-band karyotyping combinated with single nucleotide polymorphism array(SNP-array)analysis was conducted on the amniotic fluid collected from a 25-week pregnant woman diagnosed as"fetus AS";chromosome karyotyping was also performed on the peripheral blood of the fetal parents.Results:The fetal karyotype analysis showed a chimeric Y-chromosome isobaric double-adherent granules.The SNP-array analysis results revealed a 11.2 Mb duplication in the Yp11.31q11.21 region and a 14.8 Mb deletion in the Yq11.21q11.23 region.Both the parents presented a normal karyotype,suggesting it was a newfound mutation.After extensive genetic counseling,the pregnant woman and her family chose to terminate the pregnancy locally.Conclusion:The chromosomal karyotype of the chimeric Y-chromosome isobaric double-adherent granules may be a contributing factor to the AS phenotype in the male fetus.The combined use of chromosomal karyotyping and SNP-array analysis on the amniotic cells is instrumental in the early diagnosis of the disease.
