OBJECTIVE: To explore the material foundation of kidney-yang-deficiency syndrome. METHODS: Two kinds of rat models of deficiency of kidney-yang were induced by adenine intragastric administration (model I) and hydrocortisone intramuscular injection (model II). One hundred rats were randomly divided into normal control group, model I group, low-dose model II group, medium-dose model II group and high-dose model II group. After model establishment, contents of serum creatinine (SCr), blood urea nitrogen (BUN), and urine creatinine (UCr) were detected by automatic biochemistry analyzer; freezing point method was used for 24-hour urinary osmotic pressure (Uosm) testing and kaolinite method was used to detect the content of urinary 17-hydroxycorticosteroid (17-OHCS). Expression of aquaporin-1 in renal tissue was observed by using real time reverse transcription polymerase chain reaction. RESULTS: The rats of model groups had the characteristics of kidney-yang deficiency syndrome. The contents of SCr and BUN were significantly higher in model I group than in normal control group and three model II groups (P<0.05), and UCr and Uosm were significantly lower (P<0.05). The level of urinary 17-OHCS and expression of aquaporin-1 in renal tissue were decreased in the model I group (P<0.05) as compared with the normal control group. Compared with the normal control group, the content of SCr was increased and urinary 17-OHCS was decreased in the medium-dose model II group, but the expression of aquaporin-1 was increased in three model II groups with a dose-dependent manner. CONCLUSION: Aquaporin-1 may be one of the material foundations of kidney-yang-deficiency syndrome.

A total of 184 teeth obtained from 102 cases(27 males and 75 females aged 17-64 years)were selected from Department of Tooth and Dental Pulp.DalJan Stomatology Hospital from June to Septembet 2007.All the teeth with deep caries which resulted from caries showed no pulp.Ninety-two teeth obtained from 54 cases were regarded as Vitrebond group which were used by light-cured glass to cover pulp;while,the other 92 teeth obtained from 48 cases were regarded as dycal group which were cured by dycal calcium hydroxide.Finally,3MZ250 resin was used in this study.A half-year following up showed that the filling shed and loose were observed in the Vitrebond group(n=1)and the dycal group(n=3)(P>0.05).There were significant differenoe in color between Vitrebond group(n=1)and dycal group(n=8)(P<0.05),suggesting 3M Vitrebond light-cured glass Was superior to dycal calcium hydroxide in decreasing dental pulp stimulation and improving dental appearance.

The prognosis of elderly (>60 years) patients with diffuse large B-cell lymphoma (DLBCL) is significantly worse compared with young patients, and there is currently no standard treatment. Elderly patients with DLBCL are highly heterogeneous, a stratification before treatment can help achieve precise medicine and improve outcome of them. R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin and prednisolone) is still the recommended treatment for fit elderly DLBCL patients; and for unfit or very old patients, chemotherapy of reduced dose or palliative treatments should be considered. Choices for relapsed or refractory patients are limited, and novel compounds or therapies that are well tolerated may have a good application prospect.

ObjectiveCurrently,adsorption materials applied to remove low density lipoprotein (LDL) still remain defects.HB-H-8 resin has not been put in use in removing LDL.This study focused on primary evaluation of adsorption capability of HB-H-8 resin.MethodsHB-H-8 resin was used in the adsorption of LDL of patient that was higher than the normal range of blood sample in dynamic test and static test in vitro.ResultsThe time of adsorption saturation was two hours,and the optimum temperature was 37℃.The results of adsorption in vitro showed that the average adsorption rates of LDL and high density lipoprotein (HDL) were 63.2％ and 1.9％,respectively.ConclusionHB-H-8 resin has LDL higher adsorption capability,thus made it to be a potential blood purification material for the removal of LDL.

OBJECTIVE: To study the effects of high-protein diet (HPD) and high-grade proteinuria in aggravating the progression of chronic renal failure (CRF) in rats. METHODS: CRF with high-grade proteinuria was induced by supplying HPD in five sixth nephrectomy rats, and the changes of serum creatinine (Scr), blood urea nitrogen (BUN), endothelin-1 (ET-1), thromboxane B(2) (TXB(2)) and 6-keto-prostaglandin F(l alpha) (6-Keto-PGF(l alpha)) were observed. At the same time, the content of malondialdehyde (MDA), and the activities of glutathione peroxidase (GSH-Px) and superoxide dismutase(SOD)were measured in blood and renal tissue of the rats. RESULT: HPD and high-grade proteinuria could accelerate the damage of kidney through increasing the levels of ET-1 and TXB(2), reducing the level of 6-Keto-PGF(l alpha), and attenuating the activities of SOD and GSH-Px. CONCLUSION: HPD can accelerate the damage of kidney through inducing the high-grade proteinuria in five sixth nephrectomy rats, influencing the expression of kidney vasoactive substance, and reducing the anti-oxidation.

Objective:To observe effects of Fuzheng Huoxue Recipe on blood growth hormone (GH) and insulin growth factor(IGF-1) in chronic renal failure(CRF) rats.Methods:Platt method was adopted to make 5/6 kidney excision CRF model rat,and the rats were divided into model group,Huangqi group,Enalapril group,Danshen group,Fuzheng Huoxue Recipe group and normal control group according to the blood creatinine level after modeling.Effects of Fuzheng Huoxue Recipe on GH and IGF-1 levels in CRF rats with large quantity of urinal protein were investigated.Results:GH and IGF-1 levels in the model control group were significantly higher than that in normal control group,and after treatment of Fuzheng Huoxue Recipe,blood GH and IGF-1 levels were significantly decreased.Conclusion:Fuzheng Huoxue Recipe can decrease blood GH and IGF-1 levels in CRF rats,and can delay advances of CRF.

ObjectiveTo investigate the effects of comprehensive geriatric assessment (CGA) intervention on depression and anxiety in patients with benign prostatic hyperplasia (BPH).Methods90 patients with BPH (aged 65 years and over) from June 2009 to June 2010 were randomly assigned to control(n= 45) and CGA (n = 45) group.Control group received conventional therapy,while CGA group was given CGA and consultation therapy as well as conventional therapy.The scores of international were assayed and compared between two groups before and 6 months after treatment.ResultsThe scores of international prostate symptom score (IPSS),quality of life scale (QOLS),self-rating depression scale (SDS) and self-rating anxiety scale (SAS) in control (t= 11.0,5.84,7.08and 9.68,respectively) and CGA (t= 14.0,10.4,9.16 and 6.1,respectively)group 6 months after treatment reduced as compared with those before treatmen (all P ＜ 0.01).After 6 months of treatment,the scores of IPSS,QOLS,SDS and SAS in CGA group were lower than in control group (t= 4.25,5.55,3.45 and 2.88,respectively,all P＜0.01).ConclusionsCGA intervention can improve the quality of life in BPH patients and alleviate their depression and anxiety.

One hundred forty-four residents registered at department of anesthesia of West China Hospital from 1999 to 2010.The duration of residency training is 5 years (3 + 2).The residents enrolled during 1999-2002 were on the staff.They were assigned to work at this hospital after graduation from medical school and became staff anesthesiologist of this hospital after 5 year training.The residents enrolled during 2003-2010 were trainees and not on the staff.They had to apply for a job as anesthesiologist somewhere after 5 year training.After 3 year training the residents are qualified to undergo subspecialty training.Thirty-nine of the 144 residents dropped out of the training program.The reasons for their withdrawing from the program included finding a regular job,failing the qualifying examination,changing profession studying abroad and death.In order to reduce dropout rate,correct public opinion on the importance of residency training,raising the quality of the residents and improving income of the residents are needed.

There lack scientific methods for evaluating the treatment of cancer pain with external therapies of traditional Chinese medicine (TCM). The level of clinical study in this field needs to be improved. The authors assert that when external therapies of TCM are applied to treat cancer pain, different types of cancer pain should be distinguished and treatment should be applied according to such a differentiation. Under this framework scientific evaluation can be conducted. The authors also assert that the findings of randomized, blinded and controlled trials should be given particular attention, and it is necessary to include titration of morphine into clinical trails of external therapies for the treatment of cancer pain, not only complying with the three-ladder principle for treating cancer pain suggested by the World Health Organization, but also not influencing the effect evaluation of external therapies of TCM on cancer pain. Patient diaries recording pain were revised as observation indexes. The primary indicator of efficacy was the pain intensity score and the secondary indicators were the equivalent of morphine and the remission rate of pain. The time to onset, remission duration and comparison of assessment of pain influence can mirror the characteristics of external therapies of TCM on cancer pain.

OBJECTIVE: To study the antineoplastic mechanism of Pingfei Mixture. METHODS: Thirty C57BL mice bearing Lewis pulmonary carcinoma were randomly divided into 3 groups: saline control group, Pingfei Mixture group and cisplatin group. Fifteen days later, tumor tissues and spleens were taken out and made into unicellular suspension. Argyrophil staining was taken to carcinoma cells and cultured T cells. KL-2 style cell image analysis system was used to analyze the rate between AgNORs and nuclear region (I.S). RESULTS: There were dense brownish-black granules in tumor cell nuclear of saline control group. The brownish-black granules of Pingfei Mixture group and cisplatin group were less than those of saline control group. The differences of T cell I.S in these three groups were significant. The I.S of Pingfei Mixture was higher than that of the other groups, and the I.S of the cisplatin group was the lowest. CONCLUSION: Pingfei Mixture can inhibit tumor cell proliferation, although the effect is inferior to cisplatin. Pingfei Mixture can also promote T cell proliferation and its effect was superior to cisplatin.
