Objective To explore the relationship between the size of the kidney and gender,age,height,weight,waist circumference then derive an estimation formula of a normal kidney size for different people.Methods We investigated 1 000 normal cases who accepted the examination in Tianjin Medical University General Hospital from December 2011 to April 2012,including 462 males,538 females,aged 21-78 years.All the investigated subjects were healthy except for hypertension,diabetes,coronary heart disease.Blood urea nitrogen (BUN) and creatinine (Cr),fasting glucose,uric acid,routine urine test were all in the normal range.Height,weight,and waist circumference were measured for all the subjects.The renal length and transverse diameter in supine coronal sections,anteroposterior diameter in vertical cross-section of the renal hilum were measured by the same technical experts with Philip iU22 C5-1,3.5 MHz convex array probe.Results The right and left kidney size both are significantly related to height (right r=0.845,left r=0.876,P＜0.01).By multiple regression analysis,there was a significant association between height,weight,body surface area and kidney size (R2＞0.5).Linear regression formula for the kidney length and the height(H,cm):Kidney length of men:right 0.059×H+0.144; left:0.061 ×H+0.287.Kidney length of women:right 0.039×H+3.679; left:0.035×H+4.454.Regardless of gender,the formula of left kidney length:0.052× H+0.721.Linear regression formula about the left kidney length and the height,body weight and body surface area (unit:H cm,W kg,BSA m2):0.114×H+0.139×W-10.287×BSA+2.112.Conclusion There is the best correlation between kidney length and height.Height,weight,body surface area have great influence on kidney size.

Objective:To investigate the apoptosis by thiocoraline in combination with cisplatin on cervical cell line c4-1 and Hela and its mechanism. Methods:Different concentrations of thiocoraline and cisplatin alone or in combination used for cultured c4-1 and Hela cells. The inhibition of cell proliferation was detected by MTT assay,and the apoptosis was detected by Hoechst 33342 and AO-EB staining. The expressions of the protein Bax,Bcl2,p53,p21 were detected by Western blot. The cell cycle of c4-1 and Hela cells were detected by Flow cytometry. Results: The cell proliferation activity of c4-1 and HeLa cells were inhibited obviously by different concentrations of thiocoraline and cisplatin alone or in combination. The inhibition effect was in a dose-dependent manner. Meanwhile, when the concentrations of thiocoraline and cisplatin were 10 nmol/L and 4 μmol/L, respectivity the inhibitory effect was most significant (P<0. 05);Hoechst 33342 and AO-EB staining showed that the cell apoptosis effect was more obvious on thiocoraline in combination with cisplatin. The Western blot showed that the expressions of the protein Bax,p53,p21 were significantly up-regulated, and the Bcl2 was significantly down-regulated. Conclusion:Thiocoraline combination with cisplatin could up-regulate the expression of the protein Bax,p53,p21 and down-regulation the expression of Bcl2 to inhibition the proliferation and promotion apoptosis of cervical cell line c4-1 and Hela.

[ABSTRACT]OBJECTIVETo investigate the effect of accurate airway humidification on hemorrhage, pharyngalgia, mucosal edema and sputum viscosity in patients with low-temperature plasma coblation-assisted tonsillectomy.METHODS58 cases were divided into three groups by using random numbers.In accurate airway humidification group, atomizing inhalation was carried out by AIRVOTM series apparatus; in oxygen atomizing group, budesonide suspension was used; in control group, saline was used. We evaluated the hemorrhage, pharyngalgia, mucosal edema and sputum viscosity in 3 consecutive postoperative days.RESULTSPharyngalgia in accurate airway humidification group and in oxygen atomizing group were both significantly reduced than that of the control group (P<0.001). Besides, in accurate airway humidification group, mucosal edema and sputum viscosity were significantly improved than that of the oxygen atomizing group (P<0.05) and control group (P<0.05).CONCLUSIONAccurate airway humidification could reduce the complications such as pharyngalgia, mucosal edema and purulent sputum after low-temperature plasma coblation-assisted tonsillectomy, and could accelerate recovery from surgery.

Objective To assess the relationship between maternal plasma tumor necrosis factor-related apoptosis-inducing ligand ( TRAIL ) before 20 weeks′gestation and hypertensive disorder complicating pregnancy (HDCP);and to evaluate the predictive value of plasma TRAIL for HDCP.Methods A 2-phase screening/validation study was designed.In the screening phase , a nested, case-controlled study was performed , the plasma samples collected before 20 weeks′gestation from 20 women who later developed HDCP and 20 age-and gestation week-matched controls were tested in prospective screening test for protein expression profiling during pregnancy and HDCP.Plasma samples were analyzed by a human protein microarray technology designed to detect 507 proteins simultaneously.Differently expressed proteins′functional annotation and clustering were performed by using of Database for Annotation , Visualization and Integrated Discovery ( DAVID) and Gene Ontology ( GO) database.The TRAIL level of plasma samples obtained before 20 weeks′gestation from 53 women who later developed HDCP and 106 similarly matched controls were further validated by ELISA and 62 clinical risk factors were investigated.Logistic regression and ROC analysis were used to evaluate the relationship between TRAIL and HDCP and its predictive value for HDCP.Results In protein microarray analysis , 23 proteins expressed differently before 20 weeks′gestation between the two groups.Further validation results showed that TRAIL levels in HDCP patients were lower significantly (45.7 ±13.1) pg/ml than those in healthy pregnant controls (51.2 ±14.7)pg/ml, P=0.021.Multiple factor logistic regression analysis of 159 pregnancies showed that three features were finally entering the logistic model, they were:anemia (OR=4.87, 95% CI 1.05-24.26), pre-pregnancy BMI (OR=1.72, 95% CI 1.35 -2.19) and TRAIL (OR=0.96, 95% CI 0.92 -0.99).The predictive accuracy of logistic model was 81.8%.The model significantly increases the predictive value (AUC=0.81, 95%CI 0.73-0.87) compared to TRAIL as independent predictor (AUC=0.59, 95%CI 0.51-0.67).Conclusions Totally 23 proteins were expressed differentially before 20 weeks′gestation in plasma of women who later developed HDCP , confirming that HDCP is a heterogeneous disease with different biological changes.The data suggests that plasma TRAIL levels relate with the development of HDCP and its combination with pre-pregnancy BMI and anemia have a high predictive value for HDCP before 20 weeks′gestation.

In the present study, an ultra performance liquid chromatography coupled with time-of-fight mass spectrometry (UPLC-TOF/MS) based chemical profiling approach was used to evaluate chemical constitution between co-decoction and mixed decoction of ginseng and Radix Aconiti Praeparata. Two different kinds of decoctions, namely co-decoction of ginseng and Radix Aconiti Praeparata: water extract of mixed two herbs, and mixed decoction of ginseng and Radix Aconiti Praeparata: mixed water extract of each individual herbs, were prepared. Batches of these two kinds of decoction samples were subjected to UPLC-TOF/MS analysis. The datasets of t(R) m/z pairs, ion intensities and sample codes were processed with supervised partial least squared discriminant analysis (OPLS-DA) to holistically compare the difference between these two decoction samples. Significant difference between the two decoction samples was showed in the results of positive ion mode. The contents of hypaconitine and deoxyaconitine decreased, while that of benzoylmesaconine, benzoylhypaconine and dehydrated benzoylmesaconine increased in the samples of co-decoction of ginseng and Radix Aconiti Praeparata. The content of diester-diterpenoid alkaloids decreased, while that of monoester-diterpenoid alkaloids increased, which is probably the basis of toxicity-attenuated action when combined ginseng with Radix Aconiti Praeparata.

Objective To study the effect of high intensity focused ultrasound(HIFU)ablation on microvessel density(MVD)and vascular endothelial growth factor(VEGF)in rabbit hepatcocellular carcinoma (HCC)models.Methods The VX2 t umor cells were planted in the hepatic left-central lobe on 30 rabbits.All animals were divided into two groups randomly:HIFU group(n=25)and control group(n=5).The MVD and the expression of VEGF in the HCC was detected by immunohistochemical SABC methods in control group and 0,1,3.7,16 d after the operation in HIFU group.Results The MVD and the expression of VEGF in the HCC tissue after HIFU treatment in the HIFU group were decreased significantly as compared with those in the control group (P＜0.01).However,there was no significant difference in MVD and the expression of VEGF in the HCC tissue after HIFU treatment in the HIFU group among the different time points(P＞0.05).Conclusions HIFU treatment can effectively destroy the micovessel,repress the neovascularization and reduce the blood supply of the HCC.
