1.ELECTRON MICROSCOPIC OBSERVATION ON THE EFFECT OF ACUPUNCTURE ANALGESIA ON THE ULTRASTRUCTURE OF SYNAPSES OF CAUDATE NUCLEUS
Acta Anatomica Sinica 1953;0(01):-
The ultrastructures of synapses in the head of caudate nuclei of rats were studied by means of electron microscopic technique. The experimental group of rats, in which the pain threshold was elevated after electro-acupuncture, showed no change of the number of the granular vesicles, but a significant decrease of the number of clear synaptic vesicles (without dense core) in the presynaptic boutons. This might be correlated to release of acetylcholine in the synapse.

3.Research progress on small cell lung cancer with syndrome of inappropriate secretion of antidiuretic hormone
Chinese Journal of Clinical Oncology 2017;44(5):233-237
Many malignant tumors, most commonly small cell lung cancer, merge with syndrome of inappropriate secretion of antidi-uretic hormone (SIADH). SIADH is caused by the neuroendocrine function of tumor cells or is a side effect of chemotherapeutics. As a chemotherapeutic side effect, SIADH presents as hyponatremia. Therapy for SIADH includes both treatment for primary diseases and hyponatremia. Given that SIADH-induced hyponatremia aggravates the prognosis and shortens the survival time of patients with malig-nant tumors, SIADH is an independent risk factor for prognosis. Therefore, the early diagnosis, monitoring, and treatment of SIADH will improve the prognosis of patients with malignant tumors.
4.Fiscal decentralization and public health service supply in China: A meta-regression analysis
Chinese Journal of Health Policy 2017;10(6):73-79
This paper aims to conduct a literature meta-analysis of the results of existing empirical researches about the relationship between fiscal decentralization and supply of public health service in China.It was found that the different empirical results of the impact of China''s fiscal decentralization on the supply of public health services are subject to different research characteristics.The actual results of the impact, especially the significant effect, are influenced by the characteristics of the starting year, the year of termination, and the number of models, whether the model contains population density, transfer payments, degree of openness, and whether the independent variables include the fiscal expenditure decentralization.Through the funnel plot asymmetry test, it was found that there was publication bias in the sample literature.

6.Advance in Anti-depression of Adenosine (review)
Chinese Journal of Rehabilitation Theory and Practice 2010;16(4):332-334
Adenosine is an important signaling molecule of the central nervous system (CNS). Adenosine typically released in the phosphorylated form(ATP), together with neurotransmitter, both of which are encapsulated in the synaptic vesicles. Once released into the synaptic space, adenosine molecules will bind to their three categories of receptors, namely A1 receptor (A1R), A2 receptor (A2R), A3 receptor (A3R), and therefore start G protein mediated signaling pathways, resulting in various and extensive biological effects. It has been discovered in recent years that adenosine has a certain level of anti-depression effect, although its mechanisms are yet to be elucidated. This review summarized the researches focusing on anti-depression roles of both adenosine and its receptors.

Objective:To evaluate the wear resistance of four types of composite resin when they were opposed by human enamel antagonist. The relationship between pH value and wear resistance was also evaluated. Methods:Mutual wear between four types of composite resins(3 mm?20 mm?1 mm),Beautifit(B),SureFilTM(S),TE-Econom(T),Charisma (C),with same rough surface and opposing enamel was evaluated using a wear simulator of UMT-2 (n=10).Wear resistance was assessed as weight loss(g).The worn surfaces were observed with scanning electron microscope(SEM).All data were statistically analyzed with SPSS14.0.Results:SEM observation showed that the fillers particles of resin B,S were bigger than that of the others. Fillers of resin C was the smallest and the most well-distributed. Many filler particles were lost. In the acid environment,the enamel surface had the special appearance. The S,C,T composite resins were less worn. The weight loss of the T,B,S composite resins increased when pH value fell down to 4.0 (P0.05).Conclusion:The wear resistance among the different brands of composite resins are discrepant. The weight loss might be accelerated with the decreased pH value.

Objective To evaluate the effectiveness and safety of fire needle therapy for knee osteoarthritis (KOA), and provide reference for clinic and research. Methods Systematic searches were conducted in PubMed, EMBASE, the Cochrane Library, Web of science, CNKI, VIP, CBM and WanFang Data to collect randomized controlled trials (RCTs) on fire needle therapy treating KOA from inception to August 2013. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. Then meta-analysis was performed using RevMan5.2. Results A total of 8 RCTs involving 820 patients were included. According to the different measures of control groups, subgroup analyses was performed and meta-analysis results showed that compared with the routine acupuncture group, the fire needle therapy group in clinical cured rate [OR=2.12, 95% CI (1.48, 3.02), P=0.000 1] and markedly effective rate (OR=3.92, 95%CI (2.65, 5.81), P<0.000 01] aspects all have statistical difference. Compared with the warm acupuncture group, the fire needle therapy group in the markedly effective rate [OR=4.12, 95% CI (1.92, 8.87), P=0.000 3] is statistically significant, but there is no statistical difference between the two groups in clinical cured rate [OR=3.09, 95% CI (0.95, 10.05), P =0.06]. Compared with the acupuncture needle (routine acupuncture and warm acupuncture) group, the fire needle therapy group in the visual analogue scale of knee pain [OR=-0.54, 95%CI (-0.85, -0.24), Z=3.46, P=0.000 5] after treatment is statistically difference. The adverse reactions to fire needle treatment of KOA patients have not been reported. Conclusion Current clinical evidence indicates that fire needle therapy is efficient for relieving clinical symptoms of patients with KOA, and improving their quality of life. However, due to lack of enough high-quality studies, fire needle therapy has to be further studied by conducting more strictly-designed, multicenter and large-scale RCTs.
