Objective: To explore the association between CDKAL1 rs35261542, FAIM2 rs 3205718, and VGLL4 rs 2574704 polymorphisms with childhood obesity and related metabolic phenotypes to provide evidence for personalized prevention and management strategies. Methods: Based on the 2023 Long term Nutritional Health Effects of Early Childhood Nutrition Package Intervention project, the study enrolled 1 078 children aged 5-7 years from four counties in Henan (Songxian and Ruyang countries) and Guizhou (Guiding and Fuquan countries) provinces. Using BMI Z scores, 87 overweight and obese(OVOB) children were selected and matched by sex, age, and BMI Z score with 117 normal weight controls. Participants were further stratified into four metabolic phenotype groups: metabolically healthy normal weight (MHNW, n =51), metabolically unhealthy normal weight (MUNW, n =66), metabolically healthy obesity (MHO, n =31) and metabolically unhealthy obesity (MUO, n =56) based on four conventional cardiometabolic risk factor (CR) criteria. Data were collected through questionnaires, anthropometric measurements, serum biochemical tests, and KASP genotyping. The distribution of three genetic polymorphisms ( CDKAL1 rs35261542, FAIM2 rs3205718, VGLL4 rs 2574704) across metabolic subgroups was analyzed. Multivariate Logistic regression models assessed associations between these polymorphisms and obesity/metabolic phenotypes. Results: Multivariate Logistic regression analysis showed that Homozygous mutant AA genotype of CDKAL1 rs 35261542 was positively associated with OVOB( OR =3.63), MHO ( OR =11.04), MUO ( OR = 4.88 ) ( P <0.05). Homozygous TT genotype of FAIM2 rs 3205718 increased OVOB risk ( OR =4.44, P <0.05) but showed no association with metabolic phenotypes ( P >0.05). Homozygous mutant TT of VGLL4 rs 2574704 reduced the risks of MHO and MUO ( OR = 0.30, 0.24， P <0.05). Cumulative genetic effects analysis demonstrated carriers of 1 or 2 risk genotypes of rs 35261542 and rs 3205718 had progressively higher OVOB risk ( OR =2.53, 20.79), and the combination of rs 35261542 and rs 2574704 increased risks for both MHO ( OR =8.50) and MUO ( OR =5.00) ( P <0.05). Conclusions The AA genotype of rs 35261542 ( CDKAL1 ) positively correlates with childhood obesity and metabolic abnormalities. The TT genotype of rs 3205718 ( FAIM 2) increases obesity risk but not metabolic phenotypes. The TT genotype of rs 2574704 ( VGLL 4) shows protective effects against metabolic dysfunction. Risk genotypes exhibit dosedependent cumulative effects on obesity and metabolic outcomes.

Tenofovir disoproxil fumarate （TDF） is a first-line treatment for chronic hepatitis B. With increasing use worldwide， the adverse events of renal injury caused by this drug have also attracted industry attention. This article reports a 61- year-old patient with liver cancer complicated with hepatitis B virus （HBV） infection. The patient started using TDF in mid-March 2022 and developed kidney injury after 2 months of treatment， during which he received 2 courses of donafenib combined with sintilimab chemotherapy and irregular administration of diclofenac for pain relief. In this paper， Naranjo’s assessment scale was used to evaluate the drugs that may be associated with renal injury， including TDF and sintilimab， and the drugs that are suspected to be associated with renal injury are donafenib and diclofenac. The renal injury caused by TDF can be judged according to the changes in the patient’s condition， the incidence of drug-induced renal injury， clinical manifestations， occurrence time， occurrence mechanism， drug combination， and high-risk factors. The changes of serum creatinine in patients with liver cancer complicated with HBV infection after TDF should be dynamically monitored in the clinic， and the dose of antiviral drugs should be adjusted if necessary and other antiviral drugs with less impact on renal function can be selected， to provide individualized medication recommendations for tumor patients， reduce the incidence of TDF-related renal injury.

Platinum anti-tumor drugs are currently the most widely used first-line chemotherapeutic drugs in clinical practice, and their curative effects are remarkable. However, the problems of platinum drug resistance in non-small cell lung cancer, breast cancer, ovarian cancer and others seriously limit effectiveness and clinical application of platinum drugs. The occurrence of platinum drug resistance is caused by many factors. At present, the resistance mechanism of platinum drugs mainly includes the following aspects: decreasing the accumulation of platinum in cells, increasing the inactivation of platinum in cells, repairing DNA damage and tumor cell apoptosis inactivation. This article reviews the drug resistance mechanism and coping strategy of platinum anti-tumor drugs, providing ideas for the development of platinum anti-tumor drugs and references for overcoming clinical platinum drug resistance.

African swine fever virus (ASFV) infection leads to a mortality rate of up to 100%, causing devastating disasters to the pig industry. Understanding the ASFV infection and replication is therefore of great importance. ASFV has more than 150 open reading frames, among which the inner coat protein p17 encoded by the D117L gene is involved in the formation of the icosahedral structure of the virus. However, little is known about the mechanism how p17 regulates host cell function. In this study, the potential host proteins interacting with ASFV p17 were screened by immunoprecipitation technique combined with protein profiling analysis. The interactions of p17 with mitochondrial membrane protein TOMM70 and heat shock protein HSPA8 were confirmed by co-immunoprecipitation technique and laser confocal experiments. This study provides important information for further exploring the function of p17 during ASFV infection.

Objective:Based on the high-throughput detection technique of multiplex PCR combined with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, constructing the characteristic SNP profiles of different strains, and establishing a rapid, accurate and highly sensitive method for the diagnosis of bloodstream infection pathogens.Methods:Seven kinds of pathogens such as common Escherichia coli were selected as target. The multiple PCR reaction conditions was optimized, and the characteristic peaks of each target bacteria were detected by MALDI-TOF MS to establish the joint detect system. Common primer pairs and central homo-sequence primer pairs were designed to analyse the formation of primer dimer. Using simulated bacterial infection blood samples with detection system to determine specificity and sensitivity. One hundred and fifty blood samples from suspected bacteremia patients were collected from June to September 2020 in a hospital in Beijing, and the identification results were compared to traditional identification method of clinical application that are using χ 2 test. Results:The cycle threshold (Ct) value of the central homo-sequence primers that were designed were more than 38, with a delay of 6-10 cycles. The joint mass spectrometry detection system could detect seven kinds of bacteria divided into two groups at the same time. The target bacteria can be detected specific product of the peak, and the clinical strains other than the target strains only had primer peaks. All maps had non-specific miscellaneous peaks. The sensitivity of Escherichia coli could reach 50 CFU/ml, and the detection limit of other bacteria was 100 CFU/ml. The detection results of 150 patients showed that 46 cases were positive by traditional method. The positive rate was 30.67% (46/150), including two cases of mixed infection. Forty-eight cases were positive by mass spectrometry, and the positive rate was 32.0% (48/150), including three cases of mixed infections. The negative coincidence rate was 100% (101/101). The comparison of the two methods showed that the P=0.625>0.01, the Kappa=0.938, the sensitivity and specificity was 97.82%(45/46) and 97.11%(101/104), respectively. There was no significant difference between the two methods, and the results of nucleic acid mass spectrometry could also be used in clinic. Conclusions:The established detection system can not only quickly and accurately detect seven common pathogens causing bloodstream infection, and effectively shorten the time needed for traditional culture and identification, but also can detect multiple bacterial mixed infections at the same time to make up for the possibility of missed detection. Besides, the method can also be used to identify other bacteria.
