AIM: To investigate the effect of a Chinese medicime, Dan-Shao-Hua-Xian capsule, on liver fibrosis induced by CCl_4 by observation of apoptosis and cell cycle variation in the liver cells. METHODS: Animal models were produced through eight-week treatment of the rats with CCl_4, alcohol and diet of high fat/low proteins, and then administration of Dan-Shao-Hua-Xian to the rats (1 g/kg) via stomach-tube-pouring for eight weeks was performed. Liver index, serum hyaluronic acid (HA) and glutamate pyruvate transaminase (ALT) were measured and hydroxyproline (Hyp) content in urine were determined. The extent of the liver fibrosis was observed under light microscope and apoptosis and cell cycle were also examined by cytometry between the two groups. RESULTS: Compared to the liver fibrosis group, the liver index, serum HA, ALT in the treatment group decreased, the development of liver fibrosis delayed, the urine Hyp and the number of apoptosed cells and the ratio of G_0/G_1 cells increased, as well as the S phase cells decreased, yet unable to return to normal. All those changes detected were statistically significant. CONCLUSIONS: The Dan-Shao-Hua-Xian is effective in treating the CCl_4-induced liver fibrosis in rats partly by virtue of inhibition of the growth of hepatic stellate cells and induction of apoptosis.

Objective To investigate the correlations of serum prealbumin and albumin with the shortterm outcome in patients with acute cerebral infarction in different age groups.Methods Patients with acute ischemic stroke admitted to hospital with 48 h were prospectively enrolled in the study.The modified Rankin Scale was used to assess the functional outcomes at 14 d after onset,0-2 was defined as a good outcome.According to the age of the patients,they were divided into either a young and middle-aged group (＜ 60 years) or an elderly group (≥60 years).The demography,baseline clinical data and laboratory findings of the patients were compared in the overall patients and the different age groups between the good outcome group and the poor outcome group.Multivariate logistic regression analysis was used to determine the independent influencing factors of short-term outcomes.Results A total of 622 patients with acute ischemic stroke were enrolled,including 402 (64.6％) males and 220 (35.4％) females;206 (33.1％) were in the young and middle-aged group,and 416 (66.9％) were in the elderly group;310 (49.8％) had good outcomes and 312 (50.2％) had poor outcomes.There were significant differences in the proportions of patients in male,old people,hyperlipidemia,diabetes mellitus,history of previous stroke or transient ischemic attack (TIA),as well as age,body mass index,levels of prealbumin,albumin,triglyceride,high-density lipoprotein cholesterol low-density lipoprotein cholesterol total bilirubin,direct bilirubin,indirect bilirubin,urea nitrogen,and uric acid between the good outcome group and the poor outcome group (all P ＜0.05).Multivariate logistic regression analysis showed that the female (odds ratio [OR] 1.522,95％ confidence interval [CI] 1.023-2.266;P =0.038),diabetes (OR 1.789,95％ CI 1.171-2.735;P =0.007) and higher low-density lipoprotein cholesterol (OR 1.251,95％ CI 1.017-1.539;P =0.034),total bilirubin (OR 1.054,95％ CI 1.029-1.081;P＜0.001),urea nitrogen (OR 1.245,95％ CI 1.100-1.409;P=0.001),and baseline National Institutes of Health Stroke Scale (NIHSS) score (OR 2.854,95％ CI 1.027-3.628;P =0.019) were the independent risk factors for poor outcomes,and higher prealbumin (OR 0.798 95％ CI 0.633-0.979;P =0.034) and albumin (OR 0.741,95％ CI 0.693-0.988;P =0.020) were the independent predictors of good outcomes.In the young and middle-aged patients,there were significant differences in the proportions of patients with small artery occlusion as well as age,triglyceride,and high-density lipoprotein cholesterol levels between the good outcome group and the poor outcome group (all P ＜0.05);multivariate logistic regression analysis showed that diabetes (OR 2.343 95％ CI 1.127-4.871;P=0.023) and higher baseline NIHSS scores (OR 2.041,95％ CI 1.304-4.125;P =0.027) were the independent risk factors for poor outcome,and higher high-density lipoprotein cholesterol (OR 0.742 95％ CI 0.639-0.937;P =0.044)was an independent predictor for good outcome.In the elderly patients,there were significant differences in the proportions of patients in male,previous stroke or TIA,and cardiogenic embolism,as well as prealbumin,low-density lipoprotein cholesterol,total bilirubin,direct bilirubin,indirect bilirubin,and uric acid levels between the good outcome group and the poor outcome group (all P ＜ 0.05);multivariate logistic regression the analysis showed that diabetes (OR 2.797,95％ CI 1.153-4.756;P =0.039),higher baseline NIHSS score (OR 2.586,95％ CI 1.033-3.435;P =0.035) and higher low-density lipoprotein cholesterol (OR 1.304,95％ CI 1.027-1.656;P =0.029) were the independent risk factors for poor outcome,and higher prealbumin was an independent predictor for good outcome (OR 0.795,95％ CI 0.691-0.998;P =0.002).Conclusions Prealbumin and albumin are the independent predictors for short-term good outcome in patients with acute ischemic stroke.The protective effect of serum prealbumin is more obvious in the elderly population (≥60 years).

OBJECTIVE: To explore the genetic basis for a Fra(16)(q22)/FRA16B fragile site in a female with secondary infertility. METHODS: The 28-year-old patient was admitted to Chengdu Women's and Children's Central Hospital on October 5, 2021 due to secondary infertility. Peripheral blood sample was collected for G-banded karyotyping analysis, single nucleotide polymorphism array (SNP-array), quantitative fluorescent polymerase chain reaction (QF-PCR) and fluorescence in situ hybridization (FISH) assays. RESULTS: The patient was found to harbor 5 mosaic karyotypes involving chromosome 16 in a total of 126 cells, which yielded a karyotype of mos 46,XX,Fra(16)(q22)[42]/46,XX,del(16)(q22)[4]/47,XX,del(16),+chtb(16)(q22-qter)[4]/46,XX,tr(16)(q22)[2]/46,XX[71]. No obvious abnormality was found by SNP-array, QF-PCR and FISH analysis. CONCLUSION A female patient with FRA16B was identified by genetic testing. Above finding has enabled genetic counseling of this patient.

OBJECTIVE: To retrospectively analyze the results of chromosomal microarray analysis (CMA) and parental origins of unbalanced translocations among 17 patients, so as to provide reference for their genetic counseling. METHODS: The results of CMA for 7 001 samples tested in Chengdu Women and Children's Central Hospital from January 2019 to January 2022 were retrospectively reviewed. Unbalanced reciprocal translocation was defined as two non-homologous chromosomes with lost and gained segments respectively or both with gained segments, and their parental origins were identified by parental chromosomal karyotyping and/or fluorescence in situ hybridization (FISH). RESULTS: In total 17 unbalanced translocations were identified. In three cases, two non-homologous chromosomes both had gained segments, which constituted a derivative chromosome, with the total number of chromosomes being 47. In the remaining 14 cases, there was a terminal deletion on one chromosome and a terminal duplication on the other, 10 of which were confirmed by karyotyping, with the total number of chromosomes being 46. In the derivative chromosome, the lost segment was replaced by a gained segment from another chromosome. Among 15 cases undergoing parental origin analysis, 12 had paternal or maternal chromosomal abnormalities, including 11 balanced translocations and 1 unbalanced translocation. The unbalanced gametes therefore may form through meiosis. In 3 cases, the parental chromosomes were normal, indicating a de novo origin. CONCLUSION Discovery of terminal duplication and deletion or gained segments on two non-homologous chromosomes by CMA is suggestive of parental balanced translocation, which can facilitate genetic counseling and assessment the recurrence risk for subsequent pregnancies.
