Objective To study on the relationship of PTEN with clinicopathological parameters and prognosis of esophageal squamous cell carcinoma patients.Methods The expression of PTEN was detected in 62 cases of esophageal squamous cell carcinomas by immunohistochemistry.Results(1)PTEN expres- sion is negatively correlated with the depth of invasion,lymph node metastasis,distant metastasis,pTNM stage and degree of differentiation.(2)The difference of survival is significant between high and low expres- sion groups.Conclusion PTEN is correlated negatively with the clinicopathological parameters reflecting the malignant biological behavior,and is one of the significant prognostic predictors by univariate analysis.

OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.

METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.

RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).

CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

OBJECTIVE:To study the effects of podophyllotoxin derivative QW-83 on human cervical cancer HeLa cell apopto-sis and its mechanism. METHODS:After treated with 0(negative control),0.01,0.1,1 and 10 μmol/L QW-83 and positive drug etoposide(VP-16)for 48 h,proliferation inhibition rate and IC50 of HeLa cell were determined by MTT assay. The morphological changes of HeLa cell were observed by Hochest 33342 staining after treated with QW-83 [0(negative control),2.5,5,10μmol/L] for 48 h;flow cytometry was used to detect apoptosis rate;semi quantitative RT-PCR was adopted to detect the expression of apop-tosis related gene P53,Bax,Casepase-3,Casepase-8,Casepase-9 and Bcl-2 mRNA. RESULTS:Compared with negative control, 1,10 μmol/L VP-16 and QW-83 had obvious proliferation inhibition effect on HeLa cells (P<0.05 or P<0.01),and IC50 were (5.11±0.43)μmol/L and(4.96±0.54)μmol/L. Hochest 33342 staining results showed QW-83 could obviously induce cells apopto-sis and nuclear pyknosis. Flow cytometry showed QW-83 could increase apoptosis rate in concentration-dependent manner,being 16.89%-62.56%. RT-PCR showed mRNA expression of P53,Bax,Caspase-3,Casepase-8 and Casepase-9,Bcl-2/Bax increased, while mRNA expression of Bcl-2 decreased after treated with QW-83(P<0.05). CONCLUSIONS:Podophyllotoxin derivative QW-83 can induce HeLa cell apoptosis,and its mechanism may be associated with regulate mRNA expression of apoptosis related gene.

With the advance of drug development and research techniques, the drug metabolic processes and mechanism can be more deeply achieved. As the drug metabolism and pharmacokinetics process are mediated by drug metabolizing enzymes and transporters, study of drug metabolizing enzymes and transporters has become an important part for drug development. The traditional immunoassays with low sensitivity and poor specificity can not reflect the accurate expression level of drug metabolizing enzymes and transporters. We now give a brief review on the quantitative study of drug metabolizing enzymes and transporters by mass spectrometry-based proteomic approach.

Objective To explore the correlation of B-type natriuretic peptide (BNP) with blood lipids and renal function in elderly patients with coronary heart disease (CHD).Methods According to the four quantiles of BNP level,325 subjects aged 65 years and over were divided into four groups:group A (≤32.4 ng/L),group B (32.5 ng/L),group C (62.4 ng/L),group D (＞ 162.5 ng/L).The left ventricular ejection fraction (LVEF),left ventricular end-diastole dimension (LVEDD),levels of blood lipids and renal function were compared among the groups.Results With the increase of BNP level,the LVEF was gradually decreased [(63.3±8.2) ％,(59.6±7.4) ％,(57.9±9.7)％,(55.2±10.6)％,respectively,F=11.54,P＜0.01] and the LVEDD was gradually increased (F=6.76,P＜0.01),the level of triglyceride (TG) was gradually decreased (F=2.73,P ＜0.05) in group A,B,C and D.Creatinine clearance was gradually decreased [(1.24±0.31) ml ·s-1 · 1.73 m-2,(1.21±0.31) ml· s-1 · 1.73 m-2,(1.24±0.29) ml · s-1 · 1.73 m 2,(1.09± 0.33) ml · s-1 · 1.73 m-2,respectively,F=3.62,P＜0.05],and blood urea nitrogen was gradually increased (F=4.43,P＜0.05) in group A,B,C and D.Multi-linear regression analysis showed that levels of total cholesterol,triglyceride,low density lipoprotein-cholesterol,high density lipoproteincholesterol,very low density lipoprotein-cholesterol,creatinine clearance and blood urea nitrogen were influencing factors for BNP (all P＜0.05).Conclusions BNP level can be used as a sensitive indicator for the diagnosis of heart failure and the assessment of its severity.The levels of blood lipids and renal function are associated with BNP.

Malignant pleural mesothelioma (MPM)is a malignant cancer originated from pleural meso-thelial cell.The diagnosis of MPMis based on biopsy of pleura and immunohistochemistry.The current treat-ment of MPM is multimodality therapy including surgery,radiotherapy,chemotherapy and immunotherapy. There are two major surgical procedures:extrapleural pneumonectomy and pleurectomy/decortication.The main of radiotherapy is three-dimensional conformal radiotherapy.Cisplatinum combined with pemetrexed is the first-line chemotherapy for the patients with MPM.The principal targets for immunotherapy include regulatory T cells,cytotoxic T lymphocyte-associated antigen-4 and PD-1 .

Aim To investigate the inhibitory effect of schizandrin B( SchB) on ultraviolet radiation b ( UVB) radiation-induced apoptosis of HaCaT cells. Methods Methyl thiazolyl tetrazolium ( MTT ) assay was used to examine the effect of SchB on cell viability recovery. Cell apoptosis and necrosis were measured by Ho-chest33342 staining. The p53, p21 and Caspase-3 mRNA expressions were examined by RT-PCR. Results In this study, we found that Sch B attenuated UVB-in-duced toxicity in HaCaT cells. Through Hoechst 33342 stain, we visualized that SchB could inhibit UVB-in-duced HaCaT cell death. The result demonstrated that p53 , p21 and Caspase-3 mRNA levels decreased com-pared with the control group. Conclusions Sch B at-tenuates the UVB-induced toxicity of HaCaT by inhibi-ting apoptotic gene expression. It plays a role in anti-photoaging.

A hydrophobic low-density lipoprotein cholesterol (LDL-C) adsorbent was synthesized with lauric acid and chitosan. The condition for adsorption was obtained by investigating the influence of adsorbent amount and adsorption time. The results of adsorption in vitro showed that the average adsorption rates for total cholesterol (TC), LDL-C, high-density lipoprotein cholesterol (HDL-C) and total protein (TP) were 47.7%, 84.7%, 18.1% and 5.9% respectively. The adsorbent possesses good selectivity in removing LDL-C.
