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 investigate the effects of conductive education with routine rehabilitation on cerebral palsy. Methods 59 caseswere divided into the conductive group (n=38) and the control group (n=21). The conductive group received conductive education with routinerehabilitation and the control group received routine rehabilitation only.

Results The improvement of gross motor was not significantly different betweenthese groups (P>0.05), while the intelligence, ADL improved more in the conductive group than in the control group (P=0.001). ConclusionConductive education can promote the development of the children in ADL and intelligent.

Objective To evaluate the rat model of type 2 diabetes mellitus ( T2DM) associated with depres-sion by body weight, fasting blood glucose, manifestations, and open field test.Methods The T2DM rat model was induced by high fat diet and low dose of STZ injection, and in addition, the T2DM rats were made restraint stress for 21 days.32 Wistar rats were randomly divided into three groups: normal group ( group N) , T2DM group ( group T)and T2 DM with depression group ( group T +D) , with 8 rats in each group.After the model was established, to measure the body weight, fasting blood glucose at day 0, 7, 14, and 21, and observe the gross manifestations, drink-ing and diet, feces, urine, and mental state, and test the rat depression by open field test.Results After establish-ment of the T+D rat model, the rats in group T+D showed some symptoms, including messy dark and gloomy hair, slow movement, increasing drinking, diet, feces and urine and mental fatigue.At day 0, 7, 14, and 21, compared with the group N, the body weight of the group T and group T+D were decreased, showing a significant difference ( P<0.05;P<0.01).At day 0, 7, 14, and 21, compared with the group N, and the fasting blood glucose in the groups T and T+D were increased, with a significant difference ( P<0.01 ) .After 21 days of restraint stress, the fasting blood glucose in the group T+D was significantly higher than that in the group T ( P<0.01 ) .Compared with the group N, the total movement distance in 5 minutes in the group T+D was reduced, but without a significant differ-ence (1532.6 ±126.8 cm vs.940.5 ±208.3 cm, P>0.05).Compared with the group N, the movement speed in 5 minutes in the group T was significantly slower than that in the group T , with a significant difference ( 5.1 ±0.4 cm/s vs.2.9 ±0.6 cm/s, P<0.05 ) , and even more slower than that in the group T +D, with a significant differ-ence (5.1 ±0.4 cm/s vs.2.4 ±0.5 cm/s, P<0.01) .Conclusions A rat model of type 2 diabetes mellitus as-sociated with depression has been successfully established by high fat diet and injection of low dose streptozotocin in combination with restraint stress for 21 days.This rat model is useful for further relevant studies.

Objective To investigate the changes of peripheral blood tacrolimus concentration and lymphocyte subsets in the uterus transplant recipient,and provide the evidence for monitoring the immune status after uterus transplantation.Methods The peripheral blood tacrolimus concentrations of the uterus transplant recipient during 1 year after transplantation were measured with the microparticle enzyme immunoassay (MEIA).Meanwhile,the whole blood cell counts and lymphocyte subsets were determined by the blood analyzer and flow cytometer,respectively.Results The blood tacrolimus concentrations of the uterus transplant recipient in the first month and second month after transplantation were (13.51 ± 3.92) ng/mL and (15.58 ± 1.19) ng/mL,respectively.The lymphocyte absolute counts were normal before transplantation.At the fifth day after transplantation,the counts of CD3 + T lymphocytes,CD4 + T lymphocytes,CD8 + T lymphocytes and NK cells and the ratio of CD4/CD8 were significantly decreased.One week after transplantation,the counts of CD4 + T lymphocytes were recovered to the normal range and maintained,but its recovery was slower than that of CD8 + T lymphocytes.The ratio of CD4/CD8 ranged from 0.4 to 0.8 during 10 days after transplantation,and increased and maintained between 0.8 and 1.1 after that.The counts of NK cells increased gradually from the 10th day after transplantation,but still did not recover to the level before transplantation even at the 20th day after transplantation.However,the counts and percentages of B lymphocytes did not decrease but increased at the fifth day after transplantation,and recovered to normal gradually from the 10th day after transplantation.There was no significant correlation between the CD3 + T lymphocyte count and blood tacrolimus concentration.Conclusion The dynamic changes of blood lymphocyte subsets and tacrolimus concentration exist in the uterus transplant recipient,which need to be further verified by a large amount of clinical data.

Objective To verify and monitor the performance of accuracy, precision and comparability of 26 clinical biochemical analytes (29 methods) in the six centers involved in multi-centers reference intervals research, and to ensure the reliability of theirmeasurement results.Methods During the period of the systems evaluating, two levels of commercial quality control materials and fresh frozen human serum reference materials were applied to verify the performance of inter-laboratory precision and accuracy of analysis systems. During the period of samples testing, the commercial quality control materials were measured whenever samples were analysed, the fresh frozen serum reference materials were measured once a month.The coefficient of variations (CVs), bias and total errors were calculated to assess the precision, accuracy and comparability.Results Verification of precision and accuracy: ( 1 ) the ranges of CVs of 29 methods in the six laboratory laboratories were 0.4%-6.0%, the CVs of all 29 methods met the criterion . (2) The overall average bias of the analysis systems of 21 analytes (24 methods) ranged from -5.15%( ALT) to 4.46% ( Ur ) .Among 24 methods the overall average bias of TP, Glu-GOD, Ur, Cl, Ca exceeded the acceptable range.The quality assessment during the period of samples testing:(1) The overall average bias ranged from -1.95%(Ca) to 2.92%(Ur), median 1.26%, they all met the requirements of relevant standards.( 2 ) When commercial control materials were tested, the requirements of CVs were fulfilled for most methods in the six laboratories,and the CVs of TP, Alb, Cl, Ca exceeded the acceptable range.The overall average TE of all methods met the quality specification for the C-N controls material.For the C-P control material, only the overall average TE of TP (5.05%) exceeded thearceptable range while the other methods met the requirement in criterion.Conclusions The performance of precision and accuracy of the analysis systems used in the six laboratories passed the verification.During the period of sample testing, the performance of precision and accuracy of the most methods in the 6 laboratories met the requirements of quality specifications, and the overall performance was good.Because of the limitation of current technology the performance of some methods didn't fulfill the requirement of specifications, and need to be improved.

Parkinson's disease with depression belongs to the category of "tremor syndrome" and "depression syndrome" of Traditional Chinese Medicine. Its syndrome characteristics and distribution are different from simple tremor syndrome and depression syndrome. Its neuroplastic mechanism involves dopamine, serotonin, norepinephrine and brain-derived neurotrophic factor. Parkinson's disease and depression have common neuro-biological mechanisms. Therefore, Chinese medicine treatment of Parkinson's disease with depression may have a dual regulation effect.

Liver depression and spleen deficiency syndrome is common in clinical practice. It has both the symptoms of uncomfortable liver depression and poor digestion of spleen deficiency. The brain-gut peptide not only regulates the gastrointestinal tract, but also participates in the regulation of mood, which is consistent with the mechanism of liver depression and spleen deficiency syndrome. At present, there are more than 10 brain-gut peptides discovered. This paper reviews several of these brain-gut peptides that are most closely related to liver depression and spleen deficiency syndrome to explore the relationship between brain-gut peptides and liver depression and spleen deficiency.
