Objective To explore the best time point for the ipsilateral hepatocellular apoptosis and the contralateraI hepatic hypertrophy after selective portal vein embolization(SPVE)in rabbit.Methods In a randomized study design,forty rabbits were divided into 5 groups with 8 rabbits per-group,including one as the control and the other 4 were treated with SPVE during open surgery.The rabbits were killed postoperatively,in 3,7,14,21 days respectively after the embolization.The hepatic lobes volume,the ipsilateral hepatocellular necrosis rates and apoptosis index,and liver functions were determined as well. Results In the treatment groups,the average amount of the right liver volumes decreased from 46.4 cm~3 preoperatively to 46.0,44.4,42.0,39.7 cm~3 in groups of 3,7,14,21 days postoperatively;meanwhile,the left liver volumes increased from 54.0 cm~3 preoperatively to 54.5,56.3,61.7,63.9 cm~3 respectively during 3, 7,14,21 days after the procedures.The rates of future remaining live volumes(FRLV)increased from 53.8% preoperatively to 54.2%,55.9%,59.0%,61.0% at 3,7,14,21 days postoperatively.The apoptosis indexes of hepatocells from group A to E were 8.1%,12.2%,19.4%,20.1%,14.2% respectively.Conclusions SPVE leads to atrophy of the ipsilateral hepatic lobe and hypertrophy of contralateral lobe,indicating that hepatocytes undergone apoptosis,rather than necrosis.The time point is 7 to 14 days.

Serum cytokine concentrations were determined in patients with Graves'disease(GD)before and after treatment of thiamazole.Serum soluble interleukin-2 receptor(sIL-2R)level was markedly raised before treatment as compared with normal subjects and returned to normal after 3 month therapy.Serum IL-8 level was lowered in GD patients and showed no change after 3 month therapy.No relationship between IL-8 and other markers was found.Serum IL-1?,IL-6 and TNF-?levels in GD patients showed no difference with those in normal controls.

OBJECTIVETo observe the effect of Gansui Banxia Tang plus-minus Gansui and Gancao anti-drug combination on hepatic and renal functions in malignant ascites rats to explore whether the efficacy or toxicity associated with the anti-drug combination.

METHODThe male wistar rats were randomly divided into a blank group, model group, furosemide group, Gansui Banxia Tang group, Gansui Banxia Tang removed Zhigancao group, Gansui Banxia Tang removed Cugansui group, Gansui Banxia Tang removed Zhigancao and Cugansui group. In addition to normal feeding, every morning except for the blank group and model group, the rest of the group was given drugs, the control group and the model group was given distilled water, the volume is 10 mL x kg(-1). Administered five days, all rats were fasted but except water for 24 hours to collect urine. Administered nine days all rats were fasted but except water for 12 hours, we need to weigh weight of rats. When we remove the ascites, we also need to weigh weight of rats. We use the weight before removing ascites minus weight after removing ascites to indirectly measure the amount of ascites. When we remove the ascites, we need to abdominal aortic blood, centrifuge testing renin, angiotensin II, aldosterone, antidiuretic hormone and other indicators.

RESULTThe effect of Gansui Banixa Tang on increasing the net weight, lowering abdominal circumference and body weight ratio, lowering renin, angiotensin, aldosterone, antidiuretic hormone is better than the other treatment group.

CONCLUSIONIn diuresis party, the group of Gansui Banxia Tang is better than the group of Gansui Banxia Tang remove Zhigancao or Cugansui or Zhigancao and Cugansui, renin-angiotensin-aldosterone system may play a diuretic effect of its one way.

OBJECTIVETo investigate the clinical characteristics and diagnosis of mucopolysaccharidosis VII.

METHODThe clinical and biochemical features of an infant with mucopolysaccharidosis VII confirmed by enzyme assay were analyzed.

RESULTThe 2 month-old male infant showed hydrops fetalis, mental retardation, coarse face, corneal clouding, hepatosplenomegaly, hernias, Alder-Reilly granules in the leucocytes and decreased platelet (32 × 10(9)/L). The biochemical markers showed urinary glycosaminoglycans (GAG) (532.8 mg/L, controls < 70.0 mg/L). The ratio of GAG/creatinine was 161.3 (controls: 26.2 ± 11.7). Serum chitotriosidase activity was 315.8 nmol/(ml·h) [control < 53 nmol/(ml·h)]. Beta-glucuronidase activity was deficient in isolated leukocytes.

CONCLUSIONSevere form of mucopolysaccharidosis VII exhibited characteristics of hydrops fetalis, hepatosplenomegaly, coarse face, thrombocytopenia and Alder-Reilly granules in the leucocytes. The measurements of GAG in urinary and beta glucuronidase in leucocytes are critical to diagnosis and deferential diagnosis.

OBJECTIVETo evaluate the effect of sustained-release alpha-lipoic acid tablets (SRLA) on blood lipid, glucose and insulin levels in hyperlipidemic New Zealand rabbits.

METHODSTwenty-four New Zealand rabbits were randomized into normal diet group, high-fat diet group, and high-fat diet + SRLA (300 mg/tablet) group with corresponding feed. At the beginning and 4 weeks after the feeding, the serum levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), blood glucose, and serum insulin were measured, and insulin sensitivity index (ISI) was calculated.

RESULTSFour weeks after feeding with high-fat diet, the insulin levels was elevated and the ISI lowered in the New Zealand rabbits, indicating successful establishment of the animal model of hyperlipidemia. Compared with the high-fat diet group, the serum levels of TG, TC, LDL-C and insulin were significantly reduced (P<0.05), and the ISI was significantly increased (P<0.05) in high fat diet + SRLA group. But no statistically significant difference was found in the blood glucose among the 3 groups.

CONCLUSIONSRLA can significantly correct blood lipid and insulin disorders in hyperlipidemic New Zealand rabbits and prevent the occurrence of insulin resistance and hyperlipidemia.

To investigate the optimum harvesting time and utilization of mulberry leaves during different growth periods based on the content of alkaloids and flavonoids, 88 samples of 11 species of mulberry leaves were collected and analyzed. UPLC-TQ/MS method was applied and the results showed that the ingredients of alkaloids and flavonoids in mulberry leaves are quite different in different growth periods and different species. There was a sharp decline of the average content of alkaloids in all samples from October, while the content of flavonoids dropped either from October but with less volatile. The content of flavonoids in M. atropurpurea was much higher than alkaloids, while M. australis was opposite completely. There was a sharp decline of alkaloids in M. cathayana and M. mongolica from Tuly to August, however, the content of alkaloids and flavonoids in M. alba is neither too high nor too low. In summary, it is more suitable to harvest tender mulberry leaves harvested from the end of September to beginning of October that provide a scientific evidence for rational harvest and comprehensive utilization of mulberry leaves.

BACKGROUND: Mesenchymal stem cells are a kind of adult stem cells with self-renewal and multi-directional differentiation potential. These cells have the functions of immunoregulation, regulation of cell growth and repair of injury. In recent years, it has been found that when inflammatory injury occurs, mesenchymal stem cells can regulate the secretion of inflammatory factors, and function on the damaged region, thereby repairing and improving tissue damage caused by inflammation. OBJECTIVE: To review the immunoregulatory effects of mesenchymal stem cells on T lymphocytes, B lymphocytes, dendritic cells and natural killer cells when the body is in an inflammatory state. METHODS: A computer-based search of PubMed and CNKI was performed for articles published from 2000 to 2018 using the keywords of"inflammatory microenvironment, mesenchymal stem cell, immune response, T cell, B cell, DC, NK cell" in English and Chinese, respectively. Seventy-six articles related to the topic and with reliable arguments were finally included in result analysis. RESULTS AND CONCLUSION: The interaction between mesenchymal stem cells and inflammatory cells determines the result of tissue damage repair. In an inflammatory state, the biological characteristics of mesenchymal stem cells will undergo certain changes, but mesenchymal stem cells can still exert immunomodulatory effects by secretion of various soluble cytokines or via cell contact. There are still many problems to be further explored to facilitate better clinical application of mesenchymal stem cells.
