OBJECTIVETo detect the expression profiles of suppressor of cytokine signaling 3 (SOCS3), interleukin (IL)-10, and tumor necrosis factor-alpha (TNF-a) in the placenta of women with intrahepatic cholestasis of pregnancy (ICP) and determine the clinical significance of the differential expressions.

METHODSPlacentas were collected from 37 ICP gravidas who delivered through cesarean section at the First Teaching Hospital of Xingjiang Medical University from October 2010 to May 2011 and from 35 healthy pregnant women (controls). SOCS3, TNF-a, and IL-10 protein levels were detected by immunoblotting and the Envision immunohistochemical method.

RESULTSTNF-a and IL-10 expression was detected in placentas of both groups, and was present mainly in the cytoplasm of trophoeytes. IL-10 expression was obviously lower in the ICP placentas than in the control placentas; meanwhile, TNF-a expression was obviously higher than in the control placentas (Z=-2.63, P less than 0.01). SOCS3 protein was significantly more abundant in the control placentas than in the ICP placentas. Furthermore, SOCS3 and IL-10 placental expressions were positively correlated (r=0.494, P less than 0.01), but there was a negative correlation between SOCS3 and TNF-a placental expressions (r=-0.472, P less than 0.01).

CONCLUSIONIn ICP, an increase of the type 1 cytokine, TNF-a, is associated with decreases of the type 2 cytokine, IL-10, and of SOCS3, which may reduce the secretion of IL-10. Furthermore, SOCS3 may contribute to ICP pathogenesis by modulating the Th1/Th2 cytokine balance.

OBJECTIVETo observe the effects of Qiangjing Tablets (QJT) on the semen quality and Fas/FasL signaling pathway in male SD rats with infertility.

METHODSModels of infertility were made in 50 male SD rats by intragastric administration of Tripterygium (GTW) for 3 weeks, and another 20 rats were taken as blank controls. Then 40 successfully established rat models were randomly divided into four groups, model control, low-dose QJT, medium-dose QJT, and high-dose QJT, the latter three groups treated intragastrically with QJT at 58 mg, 105 mg, and 233 mg per kg of the body weight per day, respectively. After 4 weeks of medication, the rats were killed for examination of semen quality and determination of the expression of the apoptosis factor FasL in the testis tissue.

RESULTSCompared with the blank controls, the model rats showed significant decreases in sperm concentration ([71.99 ± 9.72] vs [10.94 ± 3.58] x 10⁶/ml, P < 0.01), motility ([48.95 ± 4.10] vs [9.31 ± 5.79]%, P < 0.01), and viability ( [82.06 ± 6.16] vs [24.03 ± 6.93]%, P < 0.01). In comparison with the model controls, the rats in the QJT groups exhibited remarkably increased sperm concentration, motility, and viability, more significantly in the high-dose group ([59.66 ± 4.53] x 10⁶/ml, [35.45 ± 5.21] %, and [61.97 ± 9.75]%) and medium-dose group ([40.89 ± 4.90] x 10⁶/ml, [24.41 ± 4.79]%, and [60.06 ± 10.62]%) (P < 0.05 or P < 0.01). The expression of FasL was markedly reduced in the low-, medium-, and high-dose QJT groups (0.5215 ± 0.0189, 0.5371 ± 0.0364, and 0.4556 ± 0.0215) as compared with that of the model controls (0.5989 ± 0.0448 ) (P < 0.05 or P < 0.01).

CONCLUSIONBy upregulating the Fas/FasL signaling pathway, Tripterygium glycosides may induce the apoptosis of spermatogenic cells and reduce sperm concentration, motility and viability, resulting in infertility. The Chinese medicine Qiangjing Tablets can improve the reproductive function of male rats by decreasing the expression of the apoptosis factor FasL in the testis.

OBJECTIVETo investigate the effect of 5-fluorouracil (5-FU) on the expression of ATP-binding cassette superfamily G member 2 (ABCG2) in human colon cancer cell SW480.

METHODSSW480 cells were treated with various concentrations of 5-FU. CCK8 assay was utilized to detect the 5-FU IC50 to SW480 cells. Positive expression of ABCG2 was detected by flow cytometry, and mRNA expression of ABCG2 was detected by real time polymerase chain reaction (RT-PCR).

RESULTSThe 5-FU IC50 to SW480 cells increased as the drug concentration increased (P<0.05). Flow cytometry revealed that positive expression rate of ABCG2 in normal SW480 cells (group A) was (6.26±0.86)%. Immediately after treatment with 5-FU for 48 hours, the positive expression rate of ABCG2 (group B) was (3.43±1.18)% (P<0.05). In the second passage of cells after treatment with 5-FU for 48 hours, the positive expression rate of ABCG2 (group C) was (12.91±3.42)% (P<0.05). The mRNA expression of ABCG2 detected by RT-PCR was in accordance with the results from flow cytometry.

CONCLUSIONExpression of ABCG2 in SW480 cells can be affected by various concentrations of 5-FU.

BACKGROUNDBlood transfusion has been found to be a devastating factor for outcomes of hepatectomy. This study was to assess the value of major hepatectomy without blood transfusion.

METHODSWe retrospectively studied 51 patients who had undergone major hepatectomy without blood transfusion, including 29 patients with primary liver cancer, from August 1997 to December 2000. Sixty patients undergoing major hepatectomy with blood transfusion including 48 patients with primary liver cancer served as controls. Hepatectomy was performed through normothermic interruption of the porta hepatis. Intraoperative ultrasonography was performed to define tumor margins, and an ultrasound dissector was used to dissect liver parenchyma.

RESULTSIn the study group, the operative mortality and morbidity and 1-, 2-, and 3-year recurrence rates were 0%, 9.8%, 24.1%, 27.6% and 31.0%, respectively. In the control group, they were 3.3%, 28.3%, 43.5%, 54.3% and 58.7%, respectively. Significant differences were seen in morbidity and recurrence rates of patients with liver cancer between the two groups (P < 0.05).

CONCLUSIONMajor hepatectomy without blood transfusion can reduce postoperative morbidity and recurrence rate of patients with liver cancer.

This paper was aimed to explore the relationship between Artemisia annua and tumor, and investigate its anti-tumor mechanism based on the bioinformatics molecular network analysis, text mining technique and other related methods. Text mining tool Polysearch database was used to get the information, and after formatting conversion, the information was imported into the bioinformatics analysis software Cytoscape3.2.1 for visualization and subsequent bioinformatics molecular network analysis .It was shown that the A. annua was associated with the tumor by 8 key proteins： TNF,VEGF,PI3K, ALDH1, Bcl-2, MicroRNA, p38 and CASP3 by text mining technique. The main biological processes involved in its anti-tumor effect included cell cycle, post-translational protein modification, cell cycle regulation, protein ubiquitination and organelle tissues regulation. The key network analysis showed that the action may be achieved by regulation of triglyceride metabolic process, positive regulation of triglyceride metabolic process, positive regulation of triglyceride catabolic process, regulation of budding cell apical bud growth, negative regulation of mitotic cell cycle, negative regulation of meiotic cell cycle, and positive regulation of transcription factors. The results showed that the anti-tumor effect of A. annua may be associated with regulating lipid metabolism of tumor cells, decomposing large amounts of lipids, releasing energy, reducing the rate of tumor cell division and accelerating tumor cell apoptosis.

To explore the pharmacological principle of Artemisia carvifolia,the text mining technique was used. All the references of A. carvifolia were collected from PubMed database, and then the rules of the main ingredient,relative diseases, organs, tissues, proteins and metabolites were analyzed.

OBJECTIVE: To investigate the factors related to renal impairment in patients with diabetic kidney disease (DKD) from the perspective of integrated Chinese and Western medicine. METHODS: Totally 492 patients with DKD in 8 Chinese hospitals from October 2017 to July 2019 were included. According to Kidney Disease Improving Global Outcomes (KDIGO) staging guidelines, patients were divided into a chronic kidney disease (CKD) 1-3 group and a CKD 4-5 group. Clinical data were collected, and logistic regression was used to analyze the factors related to different CKD stages in DKD patients. RESULTS: Demographically, male was a factor related to increased CKD staging in patients with DKD (OR=3.100, P=0.002). In clinical characteristics, course of diabetes >60 months (OR=3.562, P=0.010), anemia (OR=4.176, P<0.001), hyperuricemia (OR=3.352, P<0.001), massive albuminuria (OR=4.058, P=0.002), atherosclerosis (OR=2.153, P=0.007) and blood deficiency syndrome (OR=1.945, P=0.020) were factors related to increased CKD staging in patients with DKD. CONCLUSIONS Male, course of diabetes >60 months, anemia, hyperuricemia, massive proteinuria, atherosclerosis, and blood deficiency syndrome might indicate more severe degree of renal function damage in patients with DKD.
