Objective To investigate the action of interlukin-2(IL-2),interlukin-6(IL-6) and its soluble receptors (sIL-2R,sIL-6R) in the first episode of depression in the patients of Uyghur nationality and the differences in IL-2,IL-6 and sIL-2R,sIL-6R levels between the responsive depressed patients and the refractory depressed patients treated with venlafaxine.Methods A case-control study design was conducted.57 first-episode patients with depression (patient group) and 55 healthy people matched with gender and age (control group) were recruited in the study.An intervention with sustained-releasing venlafaxine tablets at fixed dose of 150 mg/d was performed in the patient group.The severity of the illness was evaluated by using the Hamilton's depression scale (HAMD-17) before and after the therapy.And by calculating the reduction rate of HAMD-17 (≥ 50％ or ＜50％),the patients were divided into the responsive or refractory groups.The serum levels of IL-2,IL-6,sIL-2R and sIL-6R in patients and controls were tested by ELISA,and a re-test was done with the patients after treatment.Results There were statistical significant differences of the levels of serum IL-2,IL-6 and sIL-2R,sIL-6R between the patients and the control group (P ＜ 0.01).After treatment,the levels of serum IL-2,IL-6,sIL-2R and sIL-6R in responsive patients were significantly decreased when compared with those before the treatment(P＜ 0.01).The four indexes of refractory patients didn' t alter after venlafaxine treatment (P ＞ 0.05).There were positive correlations between HAMD,serum IL-2 (r =0.677 ; P =0.000) and IL-6 (r =0.197 ; P =0.033) before treatment in all patients.Conclusion Serum IL-2 and IL-6 may play a role in the onset of the depression.The efficacy of venlafaxine is negatively correlated with the levels of serum IL-2 and IL-6.Regulating the imbalanced inflammatory cytokines and the immune system may be one of the mechanisms of drug therapy of depression.

Objective To explore the distribution on-511C/T,-31T/C single nucleotide polymorphism of IL-1β gene among Uygur population in Xinjiang,and to analyze the correlation between IL-1β gene polymorphism and depressive disorders.Methods A total of 100 patients with depressive disorders and 120 control subjects were selected.Polymerase chain reaction and restriction fragment length polymorphism (RFLP-PCR),enzyme digestion and sequence reaction were used to detect the common-511C/T,-31T/C polymorphism of the IL-1β gene.The relationship between the polymorphism in the IL-1β gene and the severity of depressive disorders was analyzed.Results The frequencies of CC,CT,TT in-511 were 19.0％,58.0％ and 23.0％ in patient group,while those were 19.2％,55.0％,25.8％ in the control group,which did not show statistically significant differences (x2=0.266,P=0.875).The frequencies of CC,CT,TT in-31 were 24.0％,58.0％ and 18.0％ in the patient group,while those were 24.2％,58.3％,17.5％ in the control group,which did not show statistically significant differences (x2=0.0093,P=0.995).The frequencies of CC,CT,TT genotypes of the IL-1β gene polymorphism (-511 C/T,-31 T/C) were not statistically different between depressive patients and healthy controls.Conclusion The findings suggest no significant association between-511C/T,-31T/C polymorphism and depressive disorders in Uygur population of Xinjiang.

Objective To observe the improving effect of Hypericum Perforatum L Extracts (HPLES)on depression induced by chronic unpredictable mild stress in mice. Methods The depression model was established by the method of chronic unpredictable mild stress. Fifty depression model mice were divided into model control group,fluoxetine hydrochloride group (2. 6 mg / kg),Hypericum perforatum ex-tract low,medium and high (0. 2 g / kg,0. 4 g / kg,0. 8 g / kg) dose groups according to the random num-ber table method. Another 10 normal mice matched with body weight were taken as the normal control group. The mice in normal control group and the model control group were given pure water by gavage every day,and the mice in other groups were given corresponding solution by gavage for 4 weeks. In addition to the normal control group,the mice in other groups continued to undergo chronic unpredictable mild stress during gavage. The sugar water preference test and forced swimming test were performed after the last administration. Blood samples were collected from the posterior orbital venous plexus,and the levels of dopamine (DA) and brain-derived neurotrophic factor (BDNF) were measured by Elisa. The hippocampal tissues of mice were exam-ined by HE staining. Results Compared with the normal control group,the body mass of mice in the model control group decreased significantly at the first,second,third and fourth weeks ( t=2. 739,4. 162,4. 082, 3. 957;all P<0. 05). At the first,second,third and fourth weeks,the body mass of mice in the low,middle and high dose group of Hypericum perforatum extract were not significantly different from those in the model control group (all P>0. 05). Compared with the normal control group,the sugar water preference index of mice in the model control group was significantly reduced((61. 3± 4. 5)%,(52. 6± 5. 2)%; t=2. 721,P<0. 05),the swimming immobility time was prolonged(( 44. 3± 20. 00) s,(101. 8± 50. 8) s;t=2. 939,P<0. 05),the difference were statistically significant. Compared with the model control group,the sugar water preference index of mice in the low,middle and high dose group of Hypericum perforatum extract increased ((61. 8±4. 7)%,(65. 2±4. 1)%,(62. 6±5. 6)%,t=-3. 005,5. 073,-2. 928,all P<0. 05),the swimming immobility time decreased ((47. 2±17. 9) s,(54. 8±50. 3) s,(61. 3±44. 2) s; t=2. 803,1. 921,1. 903,all P<0. 05). The results of Elisa showed that compared with the normal control group,the levels of serum DA and BDNF of mice in the model control group were significantly lower (t=3. 031,8. 507,all P<0. 05); com-pared with the model control group,the levels of serum DA of mice in the low dose and high dose group of Hypericum perforatum were significantly higher (t=5. 025,3. 414,P<0. 05),and the serum BDNF of mice in the high dose group of Hypericum perforatum was also significantly higher (t=6. 098,P<0. 05),the differ-ence was statistically significant. HE staining showed that compared with the normal control group,the neu-rons in CA3 area of hippocampus in the model control group mice were seriously damaged,suggesting the es-tablishment of the mouse model. Compared with the model control group,the atrophy and degeneration of hippocampal CA3 cells in the three dose groups were significantly reduced. The atrophy and deformation of hippocampal CA3 neurons in the low,middle and high dose groups of Hypericum perforatum extract were re-lieved. Conclusion HPLES have obvious improving and antidepressant effects on the depression model mice induced by chronic unpredictable stress. The above effects may be related to the improvement of serum DA,DBNF level and reduce neuronal damage in CA3 area.

In the past ten years, the research and application of microbiome has continued to increase. The microbiome has gradually become the research focus in the fields of life science, environmental science, and medicine. Meanwhile, many countries and organizations around the world are launching their own microbiome projects and conducting a multi-faceted layout, striving to gain a strategic position in this promising field. In addition, whether it is scientific research or industrial applications, there has been a climax of research and a wave of investment and financing, accordingly, products and services related to the microbiome are constantly emerging. However, due to the rapid development of microbiome sequencing and analysis related technologies and methods, the research and application from various countries have not yet unified on the standards of technology, programs, and data. Domestic industry participants also have insufficient understanding of the microbiome. New methods, technologies, and theories have not yet been fully accepted and used. In addition, some of the existing standards and guidelines are too general with poor practicality. This not only causes obstacles in the integration of scientific research data and waste of resources, but also gives related companies unfair competition opportunity. More importantly, China still lacks national standards related to the microbiome, and the national microbiome project is still in the process of preparation. In this context, the experts and practitioners of the microbiome worked together and developed the consensus of experts. It can not only guide domestic scientific research and industrial institutions to regulate the production, learning and research of the microbiome, the application can also provide reference technical basis for the relevant national functional departments, protect the scale and standardized corporate company's interests, strengthen industry self-discipline, avoid unregulated enterprises from disrupting the market, and ultimately promote the benign development of microbiome-related industries.
