Objective To investigate the effect of adipose derived stem cells (ADSCs) on hepatic stellate cells (HSCs) in vitro and on liver fibrosis in vivo.Methods ADSCs and HSCs were isolated from adipose tissue and liver respectively in SD rats.The coculture system was set up by transwell insert.The 5th passage HSCs were cultured on the 6-well plastic plate,and ADSCs or BRLs seeded on the transwell insert.The proliferation of HSCs was tested by CCK-8 test kit.Smoothmuscle α-actin (α-SMA) expression of HSCs were tested by Western blot.Rat models of liver fibrosis was established.Rats in ADSCs treatment group were infused with ADSCs and those in control group were infused with Buffalo rat liver cells (BRLs).Liver sections were studied by immunocytochemistry.Liver hydroxyproline (Hyp) content,serum laminin (LN)and hyaluronic acid (HA) were tested,the cytokines in the culture medium were assayed.Results HSCs and ADSCs were isolated successfully.After coculture for 72 h,compared with the control group,the proliferation and activation of HSCs was inhibited by ADSCs( absorbance of each group were 2.172 ±0.107,1.424 ± 0.013,1.209 ± 0.117,F =90.605,P ＜ 0.05 ; Gray-scale values of each group were 1.4 ± 0.2,152 ± 14,258 ± 18,F =283.348,P ＜ 0.05 ),ADSCs infusion inhibits liver fibrosis in model rats ( F =77.234,65.164,58.309,all P ＜ 0.05 ).More hepatocyte growth factor(HGF) and less transforming growth factor-β1 (TGF-β1) (F=1.767,P＜0.05)and nerve growth factor (NGF) (F=2.301,P＜0.05) were secreted by ADSCs than by BRLs.Conclusions ADSCs inhibit the proliferation and activation of hepatic stellate cells.Treatment with ADSCs decreases collagen deposition in the liver and inhibits liver fibrosis.

Objective To investigate the correlation between dose and effect of thioacetamide (TAA) on rat model of intestinal endotoxemia. Methods The models of intestinal endotoxemia were induced by three different doses of TAA by gavage administration of TAA 200, 400, 600mg/kg respectively once per day for two days.The doses were given at same time point every day. Each group included 10 rats. The rats in the control group were administrated with 2 mL 0.9% NaCl saline gavage. The death of the rats was observed at 24 hours and 48 hours after administration. The blood samples of the living rats were drawn from abdominal aorta for determining the plasma endotoxin levels, serum alanine aminotransferase(ALT)and aspartated transaminase (AST) levels. The histopathological changes of liver were examined. Single factor analysis of variance was performed and comparision between groups was done using t test. Results No rat in the control group died. Two rats of 200 mg/kg TAA group, five rats of 400 mg/kg TAA group and eight rats of 600 mg/kg TAA group died during the experiment. The mean serum ALT levels of TAA model groups [(305.09±116.78)U/L,(901.67±274.31)U/L,(1454.84±473.49)U/L] were all significantly higher than that of the control group(47.81±22.61)U/L(t=14.583, 25.896 and 20.596, respectively; all P＜0.05). The mean serum AST levels of TAA model groups [(465.88±139.96)U/L, (884.37±250.90)U/L,(1889.23±159.67)U/L] were all significantly higher than that of the control group (69.33±22.04)U/L(t=12.988,18. 455 and 13.542, respectively; all P＜0.05). The mean plasma endotoxin levels of TAA model groups [(0.436±0.110)EU/mL, (0.550±0.095) EU/mL, (0.620±0.057)EU/mL] were all significantly higher than that of the control group (0.103±0.056)EU/mL(t=7.335, 5.260 and 8.191, respectively; all P＜0.05). The histological results of TAA model groups showed hepatic cell degeneration and necrosis in different degrees. Conclusions TAA with 200-600mg/kg is proper to establish the rat model of intestinal endotoxemia. The death rate of rats in the 200mg/kg TAA group is lower than those of other model groups, which suggests that 200mg/kg TAA may be the best dosage for establishing rat model for further studies.

OBJECTIVETo investigate the correlation between polymorphisms in human leukocyte antigen (HLA)-DQB 1 and primary liver cancer (PLC) with hepatitis B virus (HBV) and to search for susceptibility and resistance genes related to PLC with HBV.

METHODSOne hundred and eighteen patients with HBV-related liver cancer were enrolled from the First Hospital of Shanxi Medical University. Patients were stratified by family history of hepatitis B (39 with; 79 without) and HBV DNA positivity (60 positive, ≥1*10(3) IU/mL; 58 negative, <1*10(3) IU/mL). The HLA-DQB 1 genotype was determined by PCR and direct nucleotide sequence analysis genotyping. Allele frequencies were calculated by the direct counting method. Betweengroup comparisons were carried out with the Chi-square test or Mann-Whitney U test.

RESULTSThe allele frequencies of HLA-DQBl*0202 and HLA-DQBl*0301 were significantly higher in patients with hepatocellular carcinoma (HCC) than the control group (1 1.8% and 29.3% vs. 7.6% and 21.1%; U=2.43 and 3.09, P<0.05, RR=1.581 and 1.477). The allele frequencies of HLA-DQB1*0202 and HLADQB 1*0301 were significantly higher in patients with HCC and familial history of hepatitis B than in the normal population (14.1% and 29.5% vs. 7.6% and 21.1%; U=3.76 and 3.16, P less than 0.05, RR=1.928 and 1.495). The allele frequency of HLA-DQB 1*0301 was significantly higher in the HBV DNA positive group than in the HBV DNA negative group (35.0% vs. 23.3%; x2=5.543, P less than 0.05, RR=1.775), while the frequency of HLA-DQB1*0302 was significantly lower in the HBV DNA positive group than in the HBV DNA negative group (10.9% vs. 14.7%; x2=4.604, P<0.05, RR=0.229).

CONCLUSIONSThe HLA-DQB 1 *0202 and HLA-DQB 1*0301 alleles may represent susceptibility for PLC with hepatitis B as well as for familial hepatitis B liver cancer. The HLA-DQB 1*0301 allele may support replication of HBV DNA, facilitating progression to liver cancer. The HLA-DQB1*0302 allele may inhibit replication of HBV DNA and reduce the incidence of liver cancer.

The patient was a 6-day-and-19-hours-old girl. On March 31, 2023, she was admitted to Chongqing University JiangJin Hospital with symptoms of yellow skin staining for 3 days and fever for 6 hours. On April 1st, the Medicine Laboratory reported a critical value in blood cultures: Gram-negative bacilli, which were identified as Salmonella through mass spectrometry and biochemical tests. It was classified as non A-F group Salmonella due to negative AF and Vi serotyping results. Subsequent serum agglutination test after subculture showed O13, 23 Hz, l, w, and further results by analysis using the sequences of the 16S rRNA and gyrB genes confirmed it as Salmonellaenterica subsp. enterica Serovar Worthington Strain, consistent with the serum agglutination test result. After receiving a 14-day course of Ampicillin/Sulbact treatment for infection control, the patient′s health condition improved she was discharged from the hospital. The identification of Salmonella requires simultaneous bacterial biochemical identification and serological tests ser to ensure accurate results and provide reliable basis for etiological diagnosis.

Objective: To observe the therapeutic effects and related mechanism of hemin on the progression of hepatic fibrosis in rats. Methods: Sixty male Wistar rats were randomly divided into normal control group, 4-week model group, 6-week model group, hemin inhibitor zinc protoporphyrin-IX (ZnPP-IX) intervention group and hemin intervention group. Hemin intervention group in complex liver fibrosis model was intraperitonealy administered ZnPP-IX or hemin every other day for 2 weeks from the fourth week. The mRNA expression of HO-1, α-smooth muscle actin (α-SMA) and nuclear factor-κB (NF-κB) in the liver tissue was detected by real-time polymerase chain reaction. Immunohistochemistry was used to detect HO-1 and localization of α-SMA expression. Serum hyaluronic acid, propeptide of type III collagen and hepatic transforming growth factor beta (TGFβ), and interleukin 6 (IL-6) expressions were detected by enzyme-linked immunosorbent assay. The content of hydroxyproline in hepatic tissues was measured by alkaline hydrolysis method. One-way ANOVA was used to compare the mean of each group. The difference between the two groups was compared by independent samples t- test. P-values < 0.05 was considered statistically significant. Results: Compared with model groups and ZnPP-IX intervention group, Hemin's intervention significantly increased the expression of HO-1 mRNA (P < 0.01) and protein distribution in liver tissues, while the expression of alpha-SMA mRNA was significantly decreased (P < 0.05) in portal space and areas around the fibrotic septum, and hepatic sinus. Hyp content and serum hyaluronic acid and propeptide of type III collagen decreased significantly (P < 0.05). Meanwhile, NF-κB p65 mRNA expression and the downstream production of TGFβ and IL-6 in Hemin intervention group were also inhibited (P < 0.05). Conclusion Hemin can significantly inhibit the progression of hepatic fibrosis in rats by up-regulating HO-1 expression, and the inhibiting activity of NF-κB p65 leads to downstream of the inflammatory factors.

Objective The aim of this study is to dynamically investigate peripheral blood lymphocyte subsets in fever with thrombocytopenia syndrome (SFTS) patients at different stages,to evaluate the influence of these changes in the infection process.Methods Case-control study was used in the research.Twelveconfirmedthrombocytopeniasyndromevirus ( SFTSV ) infectedpatientswere enrolled.According to SFTS prevention guide issued by Chinese Ministry of Health,these patients were divided into two groups,recovery group and death group.For each group,dynamic profiles of the CD3 + T cells,CD4 + helper T cells,CD8 + cytotoxic T cell and CD3 - CD16 + CD56 + natural killer cells were tested by flow cytometry.Meanwhile, the relationshipsbetween these dynamicchanges and liver function,leukocytes,and platelets were analyzed respectively.Two independent-samples t test was used to compare the difference of the peripheral blood lymphocyte subsets count between the SFTS patients and healthy control.Small sample was analyzed by Mann-Whitney U test.Results In the early stage of infection,Th cells in peripheral blood of recovery group were significantly reduced and Th/Tc ratio was reversed.On day 5,7,9 of post infection,Th cell counts in peripheral blood were (740.9 ± 6.4),(836.2 ± 272.3 ) and ( 1083.6 ± 319.7 ) cells/μl respectively,which were significantly lower than health control ( 1351.4 ± 295.1 ) cells/μl ( t value was -2.883,-4.235,-2.145 respectively,all P ＜0.05).Tc cell counts were significantly more than healthy controls (690.1 ± 194.8) cells/μl through the course,which were ( 1006.3 ±356.5),(1166.4±242.4),(1102.4±245.9),(991.3±205.1) and (886.5±154.5) cells/μl on day 7,9,11,13,15 of the course (t value was 3.312,5.661,4.574,3.874,2.382,all P＜0.05).NK cells were decreased significantly from the ninth day of the course.Associated with abnormal changes of cell subsets,WBC and PLT decreased significantly,and serum ALT,AST,LDH and CK etc.were higher than normal level.With the disease recovery,the abnormality above was gradually improved.In contrast,death cases showed significant decrease in T and Th cells compared with health control (P ＜ 0.05).On day 7,8,9 of the course,the counts of total T cell were (735.9 ± 359.9),(724.9 ± 125.9),(845.3 ± 389.3) cells/μl and the counts of Th cell were ( 533.2 ± 246.9 ),( 532.1 ± 105.7 ),( 551.7 ± 86.9 ) cells/μl,significantly lower than healthy control ( 1727.9 ± 230.2 ) cells/μl and ( 1351.4 ± 295.1 ) cells/μl,with statistically differences (z value was - 2.828, - 2.342,- 2.342 and - 2.828, - 2.342, - 2.342,all P ＜ 0.05 ).On day 7,8,9 of the course,the numbers of NK cell in death group were ( 1141.8 ± 415.5),( 1047.2 ±68.4),( 1276.3 ±545.3) cells/μl,which were significantly more than health group (470.7 ± 242.2) cells/μl,with statistically differences (z value was - 2.180,- 2.335,- 2.258,all P ＜0.05).Conclusions SFTSV infection can induce cell immunity damage.The changes of lymphocyte subsets are associated with clinical classification and prognosis.Significant reduction of T cell and CD4 +cell in peripheral blood are accompanied with significant increase of NK cell,which may be a pivotal indicator of poor prognosis and play an important role in making appropriate strategy in clinical treatment.( Chin J Lab Med,2012,35:826-831 )

Objective To investigate the change and significance of follicular helper T cells (Tfh) percentage in the peripheral blood of the patients with rheumatoid arthritis (RA).Methods The RA patients treated in this hospital from September to November 2016 were selected and divided into the RA active group and RA stable group,35 cases in each group.Contemporaneous 35 individuals undergoing physical examination were selected as the healthy control group.The percentage of peripheral blood CD4+ CXCR5+ ICOS+ Tfh cells was detected by flow cytometry.The correlations between the percentage of peripheral blood Tfh cells in RA patients with the RA disease activity score 28 (DAS28),anti-CCP antibody and rheumatoid factor(RF) levels were analyzed.Results The percentage of peripheral blood Tfh cells in the RA active group was (0.84±0.16) ％,which was significantly higher than (0.64±0.15)％ in the RA stable group and (0.56±0.14)％ in the healthy control group,the difference was statistically significant (P＜0.01);moreover the percentage of peripheral blood Tfh cells in the RA stable group was also higher than that in the healthy control group (P＜0.05).The percentage of peripheral blood Tfh cells in RA patients had significantly positive correlation with DAS28 score and anti-CCP antibody level (r=0.355,0.324;P＜0.01),and had no correlation with the RF level (r=0.205,P＞0.05).Conclusion The percentage increase of peripheral blood Tfh cells in the patients with RA might be related with the pathogenesis and development of RA.
