Objective To explore the effects of finasteride therapy on the expressions of heat shock protein 70(HSP70)mRNA,heat shock protein 22 (HSP22)mRNA,tumor necrosis factor-alpha (TNF-a),interleukins-1β (IL-1β) in elderly patients with benign prostatic hyperplasia (BPH).Methods Totally 68 elderly men patients with BPH were divided into two groups:regular treatment group (n=34) and finasteride treatment group(n=34),30 elderly men patients without BPH were as control group.The blood samples of patients after treatment were collected for the detections of HSP70mRNA and HSP22mRNA with RT-PCR,meanwhile,the levels of TNF-α,IL-1β were measured by radioimmunoassay (RIA).Effect of treatment was evaluated in accordance with International Prostate Symptom Score (IPSS).Results The expressions of HSP70 mRNA and HSP22 mRNA,TNF-α,IL-1β in BPH patients were higher in finasteride group than in control group (P＜0.01).After 12 weeks therapy,the levels of HSP70mRNA,HSP22mRNA,TNF-α and IL-1β were decreased in finasteride group (P＜0.01 or P＜0.05) but no significantly difference in regular treatment group.Compared with regular treatment group,the expressions of HSP70 mRNA,HSP22mRNA and TNF-α were reduced in the finasteride group after treatment (P＜0.01 or P＜0.05),IPSS was more improved (P＜0.05),but IL-1β was not distingished between two groups (P＞0.05).IPSS was positively related to the levels of HSP70 mRNA,HSP22 mRNA,TNF-α and IL1β (r=0.4251,0.4976,0.4562,0.3627,P＜0.01 or P＜0.05).Conclusions The occurrence and development of BPH are closely related with immunoinflammatory factors.Finasteride not only affects the levels of dihydrotestosterone but also can inhibit the expression of immunoinflammatory factors to improve symptom by reducing the volume of benign prostatic hyperplasia.

Some researchers focus on research of the nature of syndromes. The methods of combining traditional Chinese medicine syndrome and diseases and the correspondence between formulas and syndromes may be used in research of the nature of syndromes. According to combined theories of zang-organ state and seven emotions in traditional Chinese medicine with stress theory in modern medicine, the authors applied the methods of chronic immobilization stress to induce liver depression and spleen deficiency syndrome in rats based on the thinking of relativity on formula and syndrome. The research showed that the central neurobiology mechanism of liver depression and spleen deficiency syndrome closely correlates to the hypothalamic-pituitary-adrenal axis, brain-gut axis, myriad central neurotrophic factors, neurotransmitters, neuropeptides and hormones and their receptors, involving in many encephalic regions such as the hypothalamus, hippocampus, cortex, amygdale, etc. The authors will combine their previous work with multi-disciplinary research, such as genomics, proteomics, metabolomics and bioinformatics in future studies, to reveal the scientific connotations of liver depression and spleen deficiency syndrome.

Xiang-thinking is the main way of thinking in the form of traditional Chinese culture, which included Xiang and thinking. In viscera theory of traditional Chinese medicine(TCM) formation, Xiang-thinking has run through and played a role in pushing forward on the formation of manifestation theories. Among five internal organs, take liver as an example. The formation of the liver manifestation is through the description of the liver and intuitive form and structure of the object, which were on the basis of the extract of abstract thinking, and the summarization on rules of the process. In this paper, the formation of liver manifestation theory was taken as an example to discuss the application of Xiang-thinking in formation of liver manifestation theory.

Objective: To discuss the application of matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) in the identification of Aspergillus and evaluate its performance. Methods: the clinical isolates of Aspergillus collected from May 2017 to March 2018 in PLA General Hospital were identified by VITEK MS V3.0 and the results were analyzed. The ITS sequencing resultswere used as the gold standard. Results: It identified 9 Aspergillus species (including 12 Aspergillus species in total) through the V3.0 database, accounting for 86.24% of the total clinical isolates. The identification rate by VITEK MS was 91.49% with 16.51% was not identified. The coincidence rate of genus was 93.62%, of which only two Aspergillus versicolor were identified to the level of the genus. According to the confidence level analysis, 88.30% of the strains obtained more than 99% of the identification rate. 13.83% of the strains did not have the identification results for the first time, with the error rate of 3.19%. After secondary extractions, the percentage of unidentified strain was reduced to 6.38%, and the identification error rate was reduced to 2.13%. Combined with traditional identification and VITEK MS identification, the correct rate of strains identification was 98.94% on genus level, and was 93.62% on species level. The influence of other fungi on Aspergillus identification was 0%. Conclusion As a powerful supplement to the traditional identification method, MALDI-TOF MS showed a lot of convenience when applied in the identification of Aspergillus, which improves the identification accuracy and the identification ability for fungi in laboratory.(Chin J Lab Med, 2018, 41: 577-582)
