BACKGROUNDCurrent knowledge about clinical and genetic risk factors for aspirin-induced gastric mucosal injury is not sufficient to prevent these gastric mucosal lesions.

METHODSWe recruited aspirin takers as the exposed group and healthy volunteers as the control group. The exposed group was categorized into two subgroups such as subgroup A as gastric mucosal injury diagnosed by gastroscopy, including erosion, ulcer or bleeding of the esophagus, stomach, or duodenum; subgroup B as no injury of the gastric mucosa was detected by gastroscopy. Clinical information was collected, and 53 single nucleotide polymorphisms were evaluated.

RESULTSAmong 385 participants, 234 were in the aspirin-exposed group. According to gastroscopy, 82 belonged to subgroup A, 91 belonged to subgroup B, and gastroscopic results of 61 participants were not available. Using the Chi-square test and logistic regression, we found that peptic ulcer history (odds ratio [OR] = 5.924, 95% confidence intervals [CI]: 2.115-16.592), dual anti-platelet medication (OR = 3.443, 95% CI: 1.154-10.271), current Helicobacter pylori infection (OR = 2.242, 95% CI: 1.032-4.870), male gender (OR = 2.211, 95% CI: 1.027-4.760), GG genotype of rs2243086 (OR = 4.516, 95% CI: 1.180-17.278), and AA genotype of rs1330344 (OR = 2.178, 95% CI: 1.016-4.669) were more frequent in subgroup A than subgroup B. In aspirin users who suffered from upper gastrointestinal bleeding, the frequency of the TT genotype of rs2238631 and TT genotype of rs2243100 was higher than in those without upper gastrointestinal bleeding.

CONCLUSIONSPeptic ulcer history, dual anti-platelet medication, H. pylori current infection, and male gender were possible clinical risk factors for aspirin-induced gastric mucosal injury. GG genotype of rs2243086 and AA genotype of rs1330344 were possible genetic risk factors. TT genotype of rs2238631 and TT genotype of rs2243100 may be risk factors for upper gastrointestinal bleeding in aspirin users.

Objective To develop a nurse-led case management practice program for ovarian cancer patients,and to investigate its application effect initially.Methods The case management practice model of ovarian cancer was formed through literature analysis,qualitative research and expert meeting method.Ovarian cancer patients who were given conventional nursing interventions from Aug 2022 to Jun 2023 and from Jul 2023 to Mar 2024 in Obstetrics and Gynecology Hospital,Fudan University were selected as the control group(n=16)and the intervention group(n=16).The patients'supportive care needs,disease symptoms and unplanned readmission rates were compared before and after intervention between two groups.Supportive Care Needs Survey Shortform 34(SCNS-SF34)was used to collect patients'supportive care needs,and M.D.Anderson Symptom Inventory(MDASI)was used to assess disease symptoms.Results The ovarian cancer case management practice program was constructed and revised to determine the qualification and professional competence of the ovarian cancer case manager,the core of practice,and the specific implementation pathway.After intervention,the total score and scores of all dimensions of SCNS-SF34 in the intervention group were lower than those of the control group(P<0.001),the total score and scores of all dimensions of MDASI in the intervention group were lower than those of the control group(P<0.05).There was no statistically significant difference in unplanned readmission rates between the two groups.Conclusion The case management practice program for ovarian cancer patients was constructed with scientific validity,which can effectively meet the care needs of patients and alleviate their disease symptoms.

OBJECTIVETo investigate the influence of hepatitis B virus (HBV)-encoded small surface protein (SHBs) on hepatic cell expression of host genes related to lipid metabolism.

METHODSThe full-length SHBs gene was amplified from HBV genotype C by polymerase chain reaction (PCR) and cloned into the pcDNA3.1(+) expression vector for stable transfection into HepG2 cells (selected by G418 screening); cells transfected with empty vector served as control. The SHBs mRNA and protein levels were detected by reverse transcription-PCR and enzyme-linked immunosorbent assay. SHBs effects on expression of genes and proteins related to lipid metabolism were detected by real-time quantitative (q)PCR and western blotting, respectively.

RESULTSThe stably transfected cell line HepG2-pn3.1-SHBs was established successfully. qPCR showed that the HepG2-pn3.1-SHBs cells had significantly down-regulated transcription of the ECHS1, APOA1 and LPL genes (0.161+/-0.043 vs. control cells: 0.210+/-0.022, t = 2.479; 0.031+/-0.007 vs. 0.094+/-0.055, t = 2.752; 0.770+/-0.036 vs. 0.982+/-0.031, t = 10.914), but significantly up-regulated ACC and SREBP-1c genes (0.113+/-0.027 vs. 0.059+/-0.022, t = -3.757; 0.019+/-0.002 vs. 0.015+/-0.001, t = -4.330). The CPT1a and PPARa genes' expression was slightly, but not significantly, down-regulated in the HepG2-pn3.1-SHBs cells (0.028+/-0.005 vs. 0.030+/-0.004, t = 1.022; 0.014+/-0.004 vs. 0.015+/-0.002, t = 0.758). Western blotting showed similar expression trends for the corresponding proteins.

CONCLUSIONSHBs alters the expression of some host genes with known functions in fatty acid synthesis and decomposition; however, it remains unclear whether the hepatitis B surface antigen can directly contribute to development of hepatic steatosis.

OBJECTIVETo explore the race- and gender-specific distribution characteristics of rs1891385A/C and rs10975519C/T polymorphism of interleukin-33 (IL-33) gene in Zhuang and Han populations.

METHODSThe polymorphisms of rs1891385A/C and rs10975519C/T of IL-33 gene in 283 subjects from Guangxi Zhuang Autonomous Region were analyzed with single base extension (PCR-SEB) and DNA sequencing to analyze the differences in their distribution frequencies between genders and between Zhuang and Han populations.

RESULTSThree genotypes (AA, AC and CC) were found in rs1891385A/C with frequencies of 64.3%, 32.5% and 3.2%, respectively. The genotype and allele frequencies of rs1891385A/C in this Guangxi population showed no significant difference between Zhuang and Han subpopulations and between genders (P>0.05), but differed significantly from those in European and African black populations (P<0.01). Three genotypes (CC, CT and TT) were identified in rs10975519C/T with frequencies of 34.3%, 53.0%, and 12.7%, respectively, showing no significant ethnic or gender-specific differences in this population (P>0.05). The genotype frequency of rs10975519C/T in this population differed significantly from those in the European and Japanese populations (P<0.01), but the allele frequencies only showed significant differences from those in the European population (P<0.01).

CONCLUSIONrs1891385A/C and rs10975519C/T polymorphisms of IL-33 gene show a race-specific difference.

OBJECTIVETo study the distribution of single nucleotide polymorphisms (SNP) of arginine-vasopressin (AVP) gene rs66818855 and rs1078152 in Chinese Guangxi healthy population in comparison with that in different ethnic populations.

METHDOSPolymerase chain reaction-single base extension (PCR-SBE) and DNA sequencing were used to detect the allele and genotype frequencies of AVP gene among 303 Chinese healthy individuals in Guangxi, China, and the results were compared with the reported frequencies in 4 other populations (HapMap-CEU, HapMap-YRI, HapMap-JPT, and HapMap-HCB) from Human Genome Project group (HapMap) data.

RESULTSWe found significant AVP gene polymorphisms in this Guangxi healthy population. The frequencies of allele and genotype of AVP gene rs66818855 and rs1078152 polymorphisms in this Guangxi population differed significantly from those in HapMap-CEU population (P<0.01), and allele frequencies of AVP gene rs66818855 polymorphism differed significantly from those in HapMap-YRI populations (P<0.05).

CONCLUSIONThe distribution pattern of AVP gene polymorphisms in this Guangxi population is significantly different from that in other ethnic populations, which might account for the difference in the morbidity of AVP-related disease among different ethnic groups and may have important indications in the study of population genetics and anthropology.

Objective To investigate the efficient method which can culture and induce embryonic stem cells to neurocyte in vitro. Methods Isolate the blastula of 3.5 d from BALB/c species mouse. Culture the cells from inner cell mass (ICM) which were isolated by mechanical method on the mouse embryonic fibroblaste cell (MEF) feeder layer or 0.1% gelatin coated dishes. The stem cells were identified by characterized morphology, alkaline phosphatase stain, differential potency in vivo and immunochemistry stain. The isolated cells were differentiated by serial induction method that mimicking the intrinsic developmental process of the neural system. Results The isolated cells were positive for alkaline phosphatatse and SSEA-1 (stage specific embryonic antigen 1). Moreover they were identified pluripotent by differentiation in vivo. Therefore the isolated cells presented the characters of ESCs. Then the isolated cells were able to differentiate into neurocytes in vitro. Conclusion Mouse embryonic stem cells isolation, culture and differentiation system has been established.
