1.Correlation between aluminum overload-induced brain neurodegeneration and monoamine oxidase B in mouse brain
Journal of Chongqing Medical University 1986;0(02):-
Objective:To adopt the brain lesion model of mouse induced by overload aluminum to study the relationship between monoamine oxidase B disorder and neurodegeneration induced by overload aluminum(Al).Method:Aluminum overload models were established by injection of 3?l AlCl3 into lateral ventricle of miceeach day for 5d.The AlCl3 solutions injected in different modelswere with different concentrations and they were 0.125%,0.25%,0.5%.On d10,d20,and d30 after the final administration of AlCl3 solution,the learning and memory function of mice,pathomorphology of hippocampi,and MAO-B activity were determined.Results:Aluminum overload elevated MAO-B activity,caused karyopyknosis and loss of neurons in CA1 area of hippocampi,in dose-and time-dependent manners.Conclusion:The results indicate that neurodegeneration induced by Al toxicity may be related to the monoamine oxidase B homeostasis interfered by Al overload.

Objective To investigate clinical characters of functional dyspepsia (FD) and organic dyspepsia (OD) and evaluate the Chinese management guideline of dyspepsia. Methods Three hundreds patients with epigastric dyspepsia symptoms received a series of examinations including a detailed investigation of symptoms, liver functions, upper gastrointestinal endoscopy and B ultrasound, and then they were divided into OD and FD groups in accordance with Rome Ⅱ criteria. Results 153 (51.0%) and 147 cases (49.0%) were ascribed to FD and OD respectively. FD occurred more often at the age of less than 40 ( P =0.006). The scores of such symptoms as bloating( P
5.Functional multi-polarization of white blood cells and its significance.
Journal of Experimental Hematology 2010;18(1):1-6
Immune and hemopoiesis are one of basic project of experimental hematology. Immune function is a essential activity of white blood cells. It was puzzled for the diversity and complexity of immune response. Polarized immune response of immune cells was discovered 30 years ago, which facilitates the study on differentiation of lymphocyte. Recently recognition on multifunctional polarized immune response of lymphocyte and monocyte/macrophage would promote to elucidate the regulatory network of immune cells, diversity and complexity of immune response as well as the study on hemopoiesis. In this paper the approach of multifunctional polarized immune response of lymphocyte, monocyte/macrophage and dendritic cells were reviewed, and their role, especially in cytokine storm and tumor pro-inflammation condition were discussed.

6.Reprogramming in origin and development of leukemia stem/progenitor cells.
Journal of Experimental Hematology 2009;17(5):1123-1126
The success of yielding induced pluripotent stem (iPS) cells from human somatic cells demonstrates the important role of reprogramming in the formation of stem/progenitor cells and initiates the exploration of the origin of leukemia stem cells. In our previous work, we have found two types of leukemia, bona fide leukemia and non-bona fide leukemia. Different leukemias originate from different leukemia stem/progenitor cells which are critical to the genesis and evolution of leukemia. Bona fide leukemia and non-bona fide leukemia originate from leukemia stem cells and progenitor cells, respectively. Recent research suggests that different types of leukemia are influenced by the reprogramming state of their origin cells.

7.Application of traditional Chinese medicine in IVF-ET.
China Journal of Chinese Materia Medica 2015;40(16):3142-3146
The factors impacting the pregnancy rate and the live birth rate mainly include ovary function disorder and low endometrial receptivity, which can cause the difficulty in embryo implantation, early miscarriage and pregnancy failure. In recent years, researchers of the traditional Chinese medicine (TCM) have made active efforts in assisting IVF-ET, so as to achieve a great advance in improving the ovary reaction, treating the ovarian hyperstimulation syndrome (OHSS), improving the follicle, embryo quality and endometrial receptivity and protecting the fetus, which had been summarized in this article.

8.Effects of Drainage on Pelvic Lymphocyst After Laparoscopic Radical Hysterectomy Combined with Pelvic Lymphadenectomy
Chinese Journal of Minimally Invasive Surgery 2016;16(12):1089-1091,1095
Objective To explore the influence of no drainage on pelvic lymphocyst following laparoscopic radical hysterectomy and pelvic lymphadenectomy . Methods A total of 105 patients with cervical cancer undergoing laparoscopic radical hysterectomy and pelvic lymphadenectomy in this hospital from January 2012 to February 2016 were divided into either non-drainage group (50 cases) or drainage group (55 cases) according to whether the pelvic drainage tube was placed after surgery .Comparative analyses on the incidence of postoperative complications such as pelvic lymphocyst were made between the two groups . Results No significant difference in lymphocyst rate was found between the two groups [27.3%(15/55) vs.24.0%(12/50), χ2 =0.147, P=0.702].The incidence of pelvic infection was lower in the non-drainage group (2.0%, 1/50) than that in the drainage group (14.5%, 8/55), but the difference was not statistically significant (χ2 =3.781, P=0.052).Other postoperative complications including urinary retention , urinary fistula, and deep venous thrombosis of lower limb had no statistical differences between the two groups (P>0.05). Conclusions Drainage after radical hysterectomy and pelvic lymphadenectomy for cervical cancer does not make a difference to the incidence of lymphocyst .Non-drainaging doesn ’ t increase the risk of infection .

Objective To investigate the feasibility of non-contrast-enhanced renal MR angiography (NCE-MRA) using time spatial labeling inversion pulse (Time-SLIP) technique,and to discuss the optimized inversion time (TI) and its relationship with age.Methods A total of 61 healthy volunteers were divided into two groups by age,22-50 years (n=32)and 51 80 years (n=29).All volunteers underwent 3.0T MRI examination with 6 different TIs sequences (1 200,1 300,1 400,1 600,1 600,1 700 ms).The vessel to-kidney signal ratio (VKR),grade of renal artery branches,grade of renal artery imaging quality were measured and analyzed.Results The VKR values were the highest at TI=1 500 ms in both sides ot kidneys.The scores of renal artery branches were gradually rising up but tending to be steady higher than 1 400 ms.Among all the subjects,the highest score of renal artery imaging quality was at TI=1 500 ms.In 22-50 years group,the highest score of renal artery imaging quality was at TI=1 500 ms.Meanwhile,the highest score was found at TI=1 600 ms in 51 80 years group.Moreover,the grade of renal artery imaging in the 22-50 years group acquired better scores compared to the 51 80 years group (all P<0.05).Conclusion Time-SLIP technique is helpful to obtain renal MRA without contrast medium.The optimized TI value is 1 500 ms.Moreover,age can affect the optimized TI value.
