There is a complicated association between the liver and diabetes mellitus.Diabetes mellitus may cause various forms of liver damage,such as nonalcoholic fatty liver disease (NAFLD),hepatic cirrhosis,hepatocellular carcinoma,liver abscess,and liver transplant complications.With the growing epidemic of diabetes mellitus,this review investigates diabetes mellitus induced liver damage.

BACKGROUND:Studies have found that a variety of biological materials can be used for preparing corneal stroma scaffolds that have good biocompatibility, but research on preparation and biocompatibility of the acel ular porcine corneal stroma scaffold is little. OBJECTIVE:To explore the preparation and biocompatibility of the acel ular porcine corneal stroma scaffold. METHODS:Acel ular porcine corneal stroma scaffold and its extract were prepared. Wel-grown human corneal stromal cel s were selected and cultured in the extract of acel ular porcine corneal stroma scaffold (experimental group) or in the complete medium (control group), respectively. After 1, 2 and 3 days of culture, the proliferation ability of human corneal stromal cel s was detected by MTT assay. In the meanwhile, human corneal cel s were directly seeded onto the acel ular porcine corneal stroma scaffold, and then the cel growth on the scaffold was detected using immunochemical method. RESULTS AND CONCLUSION:The number of human corneal stromal cel s was in a rise with time in the two groups, and absorbance values had no significant difference between two groups at different time points of culture. Human corneal stromal cel s grew wel on the scaffold, and were positive for cel integrinβ1, vimentin, aldehyde dehydrogenase 3A1, as wel as CD34, CDK2 and K-Ras. These results show that the acel ular porcine corneal stroma scaffold has no cytotoxicity, and has good biocompatibility.

Objective To study the effect of UHRF1 expression inhibition by RNA interference on the radiosensitivity of esophageal cancer cell line TE-1 and its mechanism.Methods Short hairpin RNA (shRNA) targeting UHRF1 gene was introduced into TE-1 cells by lentivector-mediated transfer.The cells were divided into three groups:non-transfected group,negative control (NC)-shRNA-transfected group,and UHRF1-shRNA-transfected group.The mRNA and protein expression levels of UHRF1 in TE-1 cells were measured by RT-PCR and Western blot before and after transfection.After transfection and X-ray radiation,the radiosensitivity of TE-1 cells was evaluated by colony formation assay; the cell cycle and cell apoptosis were determined by flow cytometry; the γ-H2AX (as a marker of DNA damage) level was measured by Western blot.Results After transfection with UHRF1-shRNA,the mRNA and protein expression levels of UHRF1 were significantly decreased in TE-1 cells,as compared with those in the NC-shRNA-transfected group and non-transfected group (0.11 vs 0.96 and 0.98,F =124.21,P =0.000;0.10 vs 0.89 and 0.94,F =125.25,P =0.000).The UHRF1-shRNA-transfected group had sensitization enhancement ratios of 1.53 (D0 ratio) and 1.95 (Dq ratio).X-ray radiation could cause G2/M arrest and increase apoptotic rate and γ-H2AX expression in TE-1 cells.Compared with the two control groups,the UHRF1-shRNA-transfected group showed significantly less G2/M arrest (F =500.15,P =0.000),a significantly higher apoptotic rate (F =100.10,P =0.000),and significantly higher residual γ-H2AX expression (F =61.00,P =0.000) at 24 hours after X-ray radiation.Conclusions RNA interference can effectively inhibit the UHRF1 expression and enhance the radiosensitivity of TE-1 cells.The mechanism may be related to cell cycle regulation,cell apoptosis,and DNA damage repair.

Objective Hepatocellular carcinoma with bile duct tumor thrombus (BDTT) is rare,and surgical treatment is currently considered as the most effective treatment.Whether resectional surgery should be carried out on these patients remains controversial.Therefore,this Meta-analysis aimed to find out the long-term survival after resectional surgical treatment.Methods We conducted a literature search on PubMed,Embase and Web of Science from inception to September 2016.11 studies were included which involved 5295 patients.Each study was evaluated using the Newcastle-Ottawa Scale.The pooled effect was calculated and the associations between BDTT and overall survival (OS) or disease-free survival (DFS)were reevaluated using Meta-analysis with hazard ratio (HR) and 95％ confidence interval (CI).Results The HR for OS and DFS was 2.34 and 1.81,the 95％ CI were 1.26 ～ 4.36 and 1.17 ～ 2.78,respectively.Conclusion HCC patients with BDTT had a bad prognosis after hepatic resection or liver transplantation.

In recent years,exciting research progress has been made on hepatic Kupffer cells.For inflammation,the study of Kupffer cells focused on its mechanism of whether and how Kupffer cells play a role in regulating inflammatory reaction,especially molecular mechanisms.For fatty liver,researchers are exploring the role of Kupffer cells in the development of fatty liver,as well as potential treatments.For the treatment of ischemia-reperfusion injury,latest protocols were based on Kupffer cells.In the area of liver transplantation,the study of Kupffer cells centered on immune tolerance and graft versus host disease (GVHD).As for tumor,current studies focused on regulatory mechanism of Kupffer cells on growth and metastasis of tumor.This article will present a review on the latest progress.

OBJECTIVETo observe the clinical effect of chronic fatigue syndrome (CFS) treated with moxibustion at Gaohuang (BL 43).

METHODSWith stratified block randomization, 72 patients accorded with inclusive criteria were divided into a moxibustion at Gaohuang (BL 43) group (moxibustion group) and an acupuncture group, 36 cases in each one. In the moxibustion group, Gaohuang (BL 43) was treated with big moxa cones as the main acupoint, 10 cones a time; Qihai (CV 6) and Zusanli (ST 36) were added with big moxa cones, 7 cones a time. In the acupuncture group, acupoints were the same as those in the moxibustion group, and twirling reinforcing method was used after qi arriving, 60 times one minute and 360° with range. In the two groups, 10-day treatment was made into one course and there were two days between courses. The treatment was given once a day for 3 courses. Changes of fatigue assessment index (FAI) before and after treatment and clinical effects were observed.

RESULTSThe total effective rate was 88.9% (32/36) in the moxibustion group, which was better than 72.2% (26/36) in the acupuncture group apparently (P < 0.05). After treatment in the two groups, FAI scores were obviously declined compared with those before treatment (both P < 0.01) and FAI score in the moxibustion group was apparently lower than that in the acupuncture group (P < 0.05).

CONCLUSIONMoxibustion at Gaohuang (BL 43) can improve the FAI score of patients with CFS and the clinical efficacy is definite.

Objective To explore the role of heme oxygenase-1 (HO-1) gene expression on murine experimental abdominal aortic aneurysm (AAA).Methods Wistar rats were divided into hemin (experimental group) and saline (control group) group randomly, and experimental AAA model was established by elastase perfusion. The specimen was obtained at postoperative day 7, and the dilatation rate was calculated. In situ hybridization was applied to detect the expression of HO-1 mRNA in aortic wall, while immunohistochemical staining was used to detect the protein expression of ICAM-1 and HO-1. Results In experimental group, the aorta dilation was inhibited and aneurysm was not observed. In experimental group, HO-1 mRNA and protein expression was strengthened (P

Objective To investigate and find a multiple treatment to reduce the mortality of sepsis patients induced by severe surgical abdominal infection.Methods While treating to severe surgical abdominal infection,inflammatory mediator bacteria,extoxin and endotoxin,immunity,dysfunction of microcirculation,nutrition and metabolism and the function of organs should be paid more attention on and considered as a whole.We also carried out 14 concrete treating measurement.Combined high dosage of anisodaminum and dexamethason were used in sbort-term.Bring forward nourishment support according to different stage of MODS and applying it in clinic could significantly reduce the companion syndrome.Oral administration of“JIE-DU-GU-BEN-TANG”which developed by our division could regulate the imbalance of immunity and inflammatory mediator.Results There were 46 patients died in 368 patients,mortality was 12.50%. Conclusion It was difficult to treat sepsis patients induced by severe abdominal infection and our new multiple treatment could significantly reduce the mortality of severe sepsis.

Objective To investigate protective effects of thrombopoietin ( TPO) on cerebral model control in rats and associated signal transduction pathway. Methods Thread embolism was performed to generate cerebral ischemia-reperfusion rat model. Eighty male SD rats were randomly divided into sham operation group, model control group, TPO group, TPO and Janus kinase 2 ( JAK2 ) kinase inhibitor ( AG490 ) group. Before 30 min of ischemia-reperfusion, TPO group was given TPO (5 μg·kg-1) by intraperitoneal injection, TPO + AG490 group was given TPO (5 μg·kg-1) before 30 min of ischemia reperfusion, then given AG490 (8 μg·kg-1), and model control group were given the same dose of 0. 9% sodium chloride solution. The observation time points were 6, 12, 24, and 48 h after ischemia reperfusion. Immunohistochemical staining and Western blotting were used to measure the protein levels of Bcl-2, JAK2 and signal transducer & activator of transcription (STAT3). TdT-mediated dUTP nick end labeling (TUNEL) was used to detect apoptosis. Results Compared with model control group, the number of apoptotic cells were significantly reduced [(67. 50±9. 37) vs. (40. 20±7. 47)], the expression levels of Bcl-2, JAK2 and STAT3 protein were significantly increased [(35. 40±7. 39) vs. (78. 70±9. 75);(35. 68±6. 75) vs. (62.35±7.53); (25.40±9.45) vs.(55.36±9.69), respectively] 24 h after ischeia reperfusion in the TPO group (all P<0. 05). Compared with the TPO group, the Bcl-2, JAK2 and STAT3 protein levels were significantly decreased in TPO and AG490 group [(78. 70±9. 75) vs. (55. 40±9. 35);(62. 35±7. 53) vs. (40. 68±5. 89); (55. 36±9. 69) vs. (30. 40±9. 39), respetively], and the number of apoptotic cells was significantly increased [(40. 20±7. 47) vs. (55. 23±7. 65)] (all P<0. 05). Conclusion TPO can inhibit cell apoptosis after ischemia-reperfusion injury, the mechanism might be related to the activation of JAK2/STAT3 signal transduction pathway through raising the expression of Bcl-2 gene.
