Journal of Guangzhou University of Traditional Chinese Medicine 2015;(5):830-833
Objective To observe the effect of modified Bazhen Decoction ( MBD) on bone marrow fibroblast growth factor-1 ( FGF-1) in chronic aplastic anemia ( CAA) patients. Methods Sixty cases of CAA were randomly divided into treatment group and control group, 30 cases in each group. Both groups were given conventional western medicine such as oral use of Stanozolol and Ciclosporin, and additionally, the treatment group received oral use of MBD. Six months constituted one treatment course for both groups. After treatment, the clinical efficiency in western medicine field and on Chinese medical syndromes was evaluated in both groups. The changes of peripheral hemogram, adverse reaction, and FGF-1 in the bone marrow of both groups were also monitored. Results ( 1) Clinical efficacy in western medicine field was 80.0% in the treatment group, and was 66.7%in the control group (P<0.05). (2) The total effective rate on Chinese medical syndromes was 100.0% in the treatment group, and was 83.3%in the control group (P<0.05). (3) After treatment, the scores of symptoms were decreased in both groups (P<0.05 or P<0.01 compared with those before treatment), and the decrease in the treatment group was superior to that in the control group (P<0.05). (4) Peripheral white blood cell (WBC) count, hemoglobin (HGB) content and platelet (PLT) count as well as bone marrow FGF-1 were increased in both groups after treatment (P<0.01 compared with those before treatment), and the increase of WBC, HGB, PLT and FGF-1 in the treatment group was superior to that in the control group (P<0.05). (5) In the aspect of the adverse reaction, the treatment group had 2 cases of hepatic fucntion injury, and one case of acne and hairiness; the control group had 2 cases of gum hypertrophy, 5 cases of hepatic function injury, and 4 cases of acne and hairiness. The control group had higher incidence of adverse reaction ( P<0.05). Conclusion MBD exerts certain therapeutic effect for CAA, and one of the possible mechanisms is related with the regulation of FGF-1 level.
2.Neurobiological Mechanisms of Two Animal Models of Relapse
Acta Laboratorium Animalis Scientia Sinica 2010;18(1):81-86
Relapse is the reinstatement of drug-seeking and drug-taking behaviors following a period of abstinence.It is one of the main characteristics of drug addiction and is also the major problem requiring immediate action for the treatment of drug addiction.In this review,in order to offer new ideas to eventually treat drug addiction,efforts are made to describe the establishment of two animal models of relapse-the drug self-administration (SA) and extinctionreinstatement procedure,and the drug-conditioned place preference(CPP) and extinction-reactivation procedure.Then attention is given to assess the criterion validity of the animal models of relapse and to explore the neurobiological mechanisms involved in relapse.

Objective To investigate the status quo of formaldehyde pollution in indoor air of the decorated houses. Methods 54 apartments that have been decorated for one month to almost two years and 52 roughcast apartments were selected and the concentrations of formaldehyde were determined by acetylacetone spectrophotometry. Results The results showed that in the same time after decorating, there was significant difference of formaldehyde concentrations between higher and lower temperature periods (P

Objective To investigate the genetic polymorphism of HPA-1 to-16 antigens in Zhejiang Han population.Methods A total of 120 samples from unrelated donors of Zhejiang were genotyped by Polymerase Chain Reaction with Sequence-Specific Primers(PCR-SSP).Results The allele frequencies of HPA-1b,-2b,-3b,-6bw,-15b were 0.0125,0.0542,0.3833,0.0125 and 0.4833,respectively.HPA-4b,-5b,-7bw,-8bw,-9bw,-10bw,-11bw,-12bw,-13bw,-14bw and-16bw alleles were not detected.The mismatch probability(MP) of HPA-3 and 15 were 0.36 and 0.37,respectively,in raneom platelet transfusion.Conclusion There is no difference of HPA polymorphism distribution between Han population in Zhejiang and those in other areas of China.The polymorphism of HPA-3 and-15 are more abundant than other HPA antigens,so they may cause alloimmunity in random platelet transfusion recipients and between mothers and fetuses.

Cell adhesion molecules(CAMs) play important roles in specifying cell-cell interactions during development,regeneration,and modification of synaptic activity.The close homolog of L1(CHL1) ,a recently identified member of the immunoglobulin superfamily of cell adhesion molecules,is localizably expressed in the nervous system.CHL1 interacts with like molecules(homophilic interaction) and non-like molecules(heterophilic interaction) on neighboring cells or the extracellular matrix to regulate axon outgrowth and fasciculation,neuronal migration and survival,synaptic plasticity and regeneration after trauma.

Pulse-taking is the most specific diagnostic method of TCM.Its significance has been recognized by ancient and modern doctors.However,at present the application and spread of pulse-taking is limited.In this paper,the author made detailed explorations of literatures and studies the value of pulse condition in guiding syndrome differentiation of liver diseases.The study shows abnormal pulse in left guan and taut pulse in cunkou location both suggest the liver is disordered.We can judge the location of diseases through pulse condition.This exploration shows pulse-taking plays important role in syndrome differentiation.But there is one thing should be paid more attention,pulse condition should be integrated with other symptoms,that will be reliable in guiding diagnosis.

Objective To study the role of cutaneous nerve and protease activated receptor 2 (PAR2)in the development of pruritus in atopic dermatitis(AD).Methods Dermal sheets were prepared from chronically pruritic skin lesions of 7 patients with AD,as well as from the normal skin of 7 healthy human controls.Double labeled immunofluorescence was performed using mouse anti-protein gene product 9.5(PGP9.5)monoclonal antibody and rabbit anti-substance P(SP)polyclonal antibody to observe the morphological changes in cutaneous nerve fibers,and Image-Pro Plus 6 software was used to semiquantitively assess the length,diameter of nerve fibers,integral optimal density of PAR2 and SP in dermal sheets.Results Immunofluoresence double staining showed that PAR2 co-expressed with PGP9.5 or SP in cutaneous nerve fibers.Compared with the normal control skin,both the total length and average diameter of PGP 9.5-expressing nerve fibers were increased(11051.8±1900.9 μm vs 7264.0±2659.9 μm,4.23±0.15 μm vs 3.95±0.15 μm,both P<0.01)in pruritic lesions,while only the average diameter of SP-expressing nerve fibers was up-regulated(3.99±0.20 μm vs 3.80±0.07 μm,P<0.05),and the total length of them remained unchanged(4304.7±1455.0 μm vs 3380.0±1735.4 μm,P>0.05).Also,increased integral optimal density was observed for SP and PAR in pruritic lesions in comparison with the normal control skin (27.71±16.52 vs 12.63±4.31.35.99±8.63 vs 22.69±9.56.both P<0.05).Conclusion Our results indicate a hyper-plasia of cutaneous nerve fibers in chronic itchv skin lesions of AD and an increase in the expression of PAR2 and SP in the cutaneous nerve fibers,suggesting that the signal enhancement in PAR2 pathway may be related to the mechanism of pruritus in patients with AD.
