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.

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.

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.

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.

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.

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.

The study is to investigate the relationship between dyslipidemia and impaired glucose tolerance (IGT). Ninety elderly nondiabetic patients (60 -84 years old) were under long-term follow-up in outpatient department. Blood lipid measurement and oral glucose tolerance test (OGTr) were performed,the two-hour glucose levels (2 hPBG) between normal and abnormal blood lipid groups were compared. We found that patients with hypertriglyceridemia had a significantly higher 2 hPBG than patients with normal blood triglyceride(P＜0. 01 ). But there were no differences in 2 hPBG levels between other dyslipidemias and normal lipid patients. OGTT screening in elderly patients with hypertriglyceridemia can be helpful in early detection and prevention of diabetes.

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.

Objective To investigate the relationship between serum soluble B7-H4(sB7-H4) expression and clinical pathological characteristics in patients with non small cell lung cancer(NSCLC),and its clinical significance.Methods 65 patients with NSCLC were selected as NSCLC group,58 patients with benign lung disease were selected as the benign lung disease group,another 45 healthy people of the same period in our hospital outpatient physical examination were selected as healthy control group.By enzyme-linked immunosorbent assay(ELISA) method,serum sB7-H4 and vascular endothelial growth factor(VEGF) were detected.The serum embryonic antigen(CEA) and cancer antigen-125(CA125) were detected by chemiluminescence method.The relationship between sB7-H4 and NSCLC and other pathological features,and the relationship of the tumor markers CEA,CA125,VEGF were analyzed.Results The level of serum sB7-H4 of the NSCLC group was (59.47±8.76)μg/L,which was significantly higher than (17.38±3.72)μg/L of the lung benign lesion group and (15.26±3.17)μg/L of the health control group,the differences were statistically significant(t=18.276,19.872,all P<0.01).The serum CEA,CA125,VEGF levels of the NSCLC group were higher than those of the lung benign lesion group and healthy control group,the differences were statistically significant(t=9.447,14.883,33.467;t=11.374,15.137,37.759,all P<0.01).The level of serum sB7-H4 of the NSCLC group after treatment was (35.47±7.46)μg/L,the difference was statistically significant compared with before treatment[(59.47±8.76)μg/L](t=4.372,P<0.01).The serum sB7-H4 level was correlated with NSCLC tissue differentiation degree,clinical stage,whether with lymph node metastasis (F=3.786,t=4.821,4.172,all P<0.01).In NSCLC patients,sB7-H4 level was positively correlated with serum CEA,CA125 and VEGF levels (r=0.643,0.727,0.586,all P<0.05).Conclusion The sB7-H4 may be involved in the occurrence and development of NSCLC,and it is expected to become a new target for NSCLC diagnosis and treatment.
