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.

Objective To investigate clinical application of critical value of platelet count and its threshold adjustment . Methods Theincidence rate and regularities of distribution of critical value of platelet count were retrospectively analyzed in pa‐tients ,whose platelet count was ≤50 × 109/L from Jan .2012 to Dec .2013 .And the suitable critical values of platelet count for dif‐ferent clinic units were set through clinical coordination .Results The platelet count were detected in 193 776 samples ,and detection results of 1 602 samples reached the critical value of platelet count (detection rate was 0 .83% ) .The critical value of platelet for he‐matology unit was adjusted to ≤10 × 109/L ,for surgical unit was adjusted to ≤50 × 109/L ,and for other units the critical value was still ≤20 × 109/L .Meanwhile ,cases were regarded as reaching the critical value when detection results of platelet count were differ by 50% in short time .Conclusion The adjustment of critical value of platelet count for different units could improve efficiency of clinic and laboratory ,and enhance safety of patients .

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.

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.

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 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.

Objective To study the cognitive tendencies in recognizing negative emotional faces.Methods The experiment used the traditional flanker paradigm for reference.Forty-eight university students (19 males,29 females) finished the flanker tasks deigned by E-Prime, and their accuracy rate and reaction time were recorded in the study.Results ANOVA revealed that,in all cases,the accuracy rate of anger was significant higher than fear and sadness (96.60% ,94.50% ,94.40% ) (P＜0.05).And when the flanking stimuli were fear faces or there were no flanking stimuli, the reaction time of anger was much shorter than fear and sadness ( respectively,fear(801.27 ± 140.99) ms,anger(723.94 ± 151.37 ) ms, sadness(812.21 ± 148.85 ) ms; fear(788.17 ±148.81 ) ms, anger ( 694.28 ± 111.99 ) ms, sadness (763.57 ± 133.91 ) ms, P ＜ 0.05 ).When the flanking stimuli were anger or sadness faces, the reaction time of anger was significant shorter than fear( respectively, fear( 824.09 ± 164.42) ms, anger (721.48 ± 124.06 ) ms, sadness ( 760.50 ± 131.12 ) ms; fear ( 798.95 ± 146.40) ms, anger (702.55 ± 136.07 ) ms, sadness (750.48 ± 133.86) ms, P ＜ 0.05).Conclusion There are no flanker effects in recognizing different negative emotional faces, but there are anger superiority effects of face recognition and cognitive tendencies, which is helpful for clinical diagnosis and treatment of some diseases associated with emotional disorders.

Objective To compare the clinical effect of povidone-iedine cream plus vagina scrubbing with traditional preoperative vaginal preparation method in order to seek a more safe,effective,convenient and efficient method to prepare the vagina.Methods 100 cases of married patients undergoing elective gynecological surgery were divided into the observation group and the control group with 50 patients in each.The observation group adopted povidone-iodine cream plus vagina scrubbing and the control group used traditional method.Two groups were prepared in the vagina before and after taking cervical swabs for bacterial culture to compare the positive rate of bacterial culture.Results Intra-group comparison of vaginal bacterial culture before and after vaginal preparation was significantly different,but no statistical significance was seen between the two groups.Conclusions Vagina preparation with povidoneiodine cream plus vagina scrubbing can not only reduce the workload of nurses but also improve patient comfort degree.
