2.Characteristics of motor neuron differentiation from stem cells
Chinese Journal of Tissue Engineering Research 2009;13(49):9739-9742
Studies have shown that embryonic stem cells and neural stem ceils could be induced to differentiate into motor neurons by adding inducing factors to the culture to improve differentiation proportion of motor neurons. The development and maturation process of motor neurons in vitro culture is similar to that in embryo, involving participation of Pax6, Nk×6.1, Olig2 and HB9. Moreover, cells with HB9 as separation mark almost differentiate into motor neurons in vitro. In addition, other types of protein marks have been used for identification of motor neuronal induced differentiation, such as neuron mark MAP-2, β-tubulin-Ⅲ, cholinergic cell mark ChAT, VAChT, Schwann cell mitogen REG2, and voltage-dependent calcium ion channel 11.2 subunit. The identification of induced differentiation of motor neurons also involves detection of function of differentiated motor neurons by two methods. One method is to detect the function of in vitro cultured motor neurons, and the other is to detect the function of transplanted motor neurons in vivo. Although induced differentiation of stem cells into motor neurons becomes mature, many issues remain in clinical application, such as cell sources of induced differentiation of motor neuron, efficiency of induced differentiation, purification of differentiated motor neurons, and function of motor neurons.
3.An experimental study of intervertebral disc nucleus pulposus coagulation by alum
Chinese Journal of Tissue Engineering Research 2008;12(23):4568-4572
BACKGROUND: The main pathological change of intervertebral disc herniation is that nucleus pulposus protrudes from ruptured annulus fibrosus, thus we can hypothesize that it is possible to prevent disc herniation prior to its protrusion by coagulating it as a whole.OBJECTIVE: To observe the coagulation effects of intervertebral disc nucleus pulposus by alum solution.DESIGN, TIME AND SETTING: A randomized controlled animal experiment was performed between September 2002 and April 2003 at Department of Animal Experiment, Peking University First Hospital, Beijing China.MATERIALS: Twenty-six healthy adult hybrid dogs, 9 for in vitro experiment and 17 for in vivo experiment, weighing 16-21kg, with no restrictions on male and female, were obtained from Department of Animal Experiment, Peking University First Hospital, Beijing, China.METHODS: Twenty canine in vitro intervertebral discs obtained from 5 dogs were randomly divided into 4 groups, with 5 discs in each group, and were put into 2.5%, 5%, 10% alum solutions and 0.9% physiological saline, respectively. Effects of disc coagulation were observed after immersing for 1 day and 10 days, respectively. Another 16 in vitro intervertebral discs obtained from 4 dogs, composed of L2/3, L3/4, L4/5, L5/6, were also injected with the above 4 experimental solutions, 0.15ml, respectively. Sixty-eight in vivo intervertebral discs were obtained from 17 dogs and divided into 4 groups: blank control group, physiological saline group, 10% alum solution+one puncture point group, and 10% alum solution+two puncture points group, 17 discs in each group. Harvesting time: 3 days, 2 weeks, 1 month and 3 months postoperation.MAIN OUTCOME MEASURES: Effects of alum solutions on the coagulation of the intervertebral discs and related histological changes were observed and an alum solution of suitable concentration was preliminarily selected. General observation, light microscopic observation and scanning electron microscopic observation were made of the nucleus pulposuses.RESULTS: In the in vitro and in vivo experiments, it was found that physiological saline did not produce the effect of coagulation on the nucleus pulposus, while immersion in the alum solution induced nucleus pulposus coagulation in the in vitro intervertebral discs. Also, as the concentration of the alum solution increased, the volume of the coagulated nucleus pulposus gradually decreased. After alum solution was injected into the in vitro intervertebral discs, no nucleus pulposus coagulation appeared. When the 10% alum solution was injected into the in vivo intervertebral discs, nucleus pulposus coagulation occurred, with the strongest coagulation effect reached at 1 month postoperation. This was manifested in the agglutination reaction centered around the puncture point. When there were 2 puncture points, 2 coagulated lumps might appear. There was an increase in the mesenchymal component of the coagulated nucleus pulposus. Histochemical and scanning electron microscopic examinations confirmed the proliferation of large numbers of collagen fibers in the mesenchyme.CONCLUSION: Alum can promote nucleus pulposus to coagulate around the injection point. This may be related to the increase of collagens and the fibrosis resulting from stimulation of the nucleus pulposus by alum solution.
4.Application of daclizumab as an immune induction therapy after liver transplantation
Chinese Journal of Tissue Engineering Research 2013;(31):5601-5606
BACKGROUND:Daclizumab can be special y combined with the inerleukin-2 receptor on the surface of activated T cells in human body, and this method can reflect the close of interleukin-2 receptor thus inferring the effect of induction therapy. At present, the daclizumab has been widely used in renal transplantation, but there is no consensus on its clinical application in liver transplantation. OBJECTIVE:To investigate the expression of serum CD25+T cells and soluble interleukin-2 receptor in the patients receiving daclizumab for liver transplantation during perioperative period. METHODS:A total of 58 patients received orthotopic liver transplant for the first time were included and then the patients were randomly divided into two groups:control group (n=28) and treatment group (n=30). The patients in the two groups were treated with tacrolimus, mycophenolate mofetil and corticosteroids triple immunosuppressive regimen. The patients in the treatment group received immune induction therapy with daclizumab, and the patients in the control group did not receive daclizumab. RESULTS AND CONCLUSION:Flow cytometry and enzyme-linked immunosorbent assay showed the expression levels of CD25+T cells in the treatment group were significantly lower than those in the control group at different time points after liver transplantation (P<0.01);and the expression levels of soluble interleukin-2 receptor in the treatment group were lower than those in the control group during transplantation and at the first day after transplantation (P<0.05, P<0.01). At 6 months after transplantation, the incidence of acute rejection was decreased in the treatment group (P<0.01). The results indicate that daclizumab can effectively suppress the expression level of CD25+T cells, as wel as the expression level of soluble interleukin-2 receptor in the peripheral blood in the early stage of liver transplantation, thus effectively reducing the rate of acute rejection.

Chinese Journal of General Surgery 2011;26(4):296-299
Objective To evaluate the treatment of obstructive jaundice caused by bile duct strictures after hepatic transcatheter arterial chemoembolization in hepatic tumor patients. Methods A retrospective review (Jun 1994 - Mar 2010) of databases at two institutions (Zhejiang Provincial People's Hospital and Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine) identified 15patients with obstructive jaundice caused by liver bile duct stricture after transcatheter arterial chemoembolization. There were 7 cases of primary liver cancer, 5 patients of liver hemangioma, 3 cases of metastatic liver cancer including 2 cases of colonic cancer and one of pancreatic cancer. Obstructive jaundice appeared in a period of 5 months to 16 months after TACE. The median time was 9 months. Results The obstructive jaundice was relieved by surgically constructed hepatobiliary drainage or PTC+stenting treatment in 13 cases and PTCD in 2 cases. All patients of hepatic hemangioma were doing well after treatment. Two cases of primary liver cancer patients with obstructive jaundice after TACE were followed up for 2 years with no recurrence of hepatic carcinoma and bile duct obstruction. The other 8 patients were followed up from 3months to 18 months until to their death from primary disease progress. Conclusions Surgery and or PTCD plus stent can effectively relieve the obstructive jaundice caused by TACE in benign or malignant liver tumors.
10.The relationship between serum leptin levels and insulin resistance in hypertensive and obesity patients.
Chinese Journal of Tissue Engineering Research 2001;5(3):58-59
Objective To investigate the relationship between serum leptin levels and insulin resistance(IR)in obesity and hypertensive patients and their role on the occurrence of hypertension or/and obesity.Methods Serum glucose,insulin,total cholesterol(TC),triglycerides(TG),HDL- C,LDL- C,uricacid(Ur),insulin sensitivity index(ISI),urinary albumin excretion(UAE)and serum leptin concentrations were determined in 66 men with essential hypertension and 67 male normotensives.The correlations between leptin and IR,and they and body mass index (BMI),blood pressure and other parameters were analyzed.Results Serum leptin levels were signifcantly higher in hypertensive and obesity subjects than in normotensive and nonobesity ones.ISI of nonobesity was higher than obesity in normotensive group,but both obesity and nonobesity ISI was higher in normotensive group than in hypertensive one .No significant change in obesity and nonobesity was found for the decreased levels and ISI(r=- 0.51,P<0.01 and r="-" 0.38,P< 0.05,respectively ) and the most singificant factors that affected serum leptin levels were BMI,waist hip ratio and ISI and the factors that affected ISI in order of importance were BMI,SBP,DBP,TG,Ur and leptin in obesity subjects of both hypertensive and ISI in above mentioned patients.The multiple regression analysis indicated that BMI was closely correlated with leptin,ISI and TG in obesity patients of both hypertensive and normotensive groups. Conclusion The increase in serum leptin levels in obesity is highly correlated with ISI and is correlated with lipid metabolism.leptin resisitance may has a indirect action in occrrence of hypertension and the correlation with IR remain to be sutdied.
