Objective To study the association of sex, body mass index and insulin resistance with serum leptin in patients with type 2 diabetes. Methods one hundred and eight patients were divided into two groups according to BMI: diabetic obese group and diabetic normal BMI group.Their weight and height were measured. Fasting plasma glucose(FPG),fasting true insulin(FTI),postprandial true insulin(PTI),and fasting serum leptin(LEP) were also measured. ISI=1/(FPG?FTI) as insulin sensitivity index were used to analyse the relation between leptin and insulin resistance. Results ⑴The serum leptin,body mass index,FTI and PTI were significantly higher in diabetic obese group than diabetic normal BMI group. ISI was significantly lower in diabetic obese group than diabetic normal BMI group. ⑵Female serum leptin levels were significantly higher than male serum leptin levels in diabetic obese group and diabetic normal BMI group. ⑶Fasting leptin was correlated with sex. Leptin was positively corrected with body mass index,FTI and was negatively corrected with ISI. Serum leptin wasn't correlated with FPG. Conclusin Serum leptin level is associated with sex,BMI and insulin resistance in patients with type 2 diabetes.

Objective To explore the influence of allergic rhinitis (AR) on patients with systemic onset juvenile idiopathic arthritis (SoJIA).Methods The study involved 44 cases with SoJIA from Department of Pediatrics,Renji Hospital affiliated to School of Medicine of Shanghai Jiaotong University from July 2008 to November 2013.The Clinical and laboratory data of all patients were recorded respectively.This was a retrospective cohort study.According to the diagnosis of allergic rhinitis (AR),children were subdivided into AR group (16 cases) and Non-AR group (28 cases).ACR Pediatric criteria (ACR Pedi) 30/ 50/70 and related indicators of SoJIA between the two groups were compared.In the AR group,the correlation between AR scores and DAS28 was analyzed.When SoJIA of the two groups relapsed,the AR group (the treatment group) received anti-rheumatism for arthritis as well as nasal spray and oral antihistamines for AR.The non-AR group (control group) only received the anti-rheumatism for arthritis.The improvement of SoJIA between the two groups was analyzed.The continuous variables were analyzed by Student's t-test or the MannWhitney U-test as appropriate.Categorical data were compared between different groups by the Chi-square test.Correlations were determined by Pearson or Spearman's ranking.Results ① In the retrospective analysis:the physician's and patients'/parents' general assessment on a 10 cm visual-analogue scale (VAS),number of joints with res-triction of movement,number of swollen joints,ESR,serum ferritin(SF) and childhood health assessment questionnaire (CHAQ) score were significantly elevated in the AR group compared with Non-AR group at the disease onset [(6.7±1.0) cm vs (4.8±1.9) cm; (6.5±1.4) cm vs (3.2±1.5) cm; 4.1±2.7 vs 2.7± 1.7; 3.4±2.4 vs 1.4±1.5; (87±35) mm/1 h vs (61±40) mm/1 h; (888±1 043) μg/L vs (311±324) μg/L; 1.6±0.5 vs 0.7±0.3,respectively; all P＜0.05].At the 3 and 6 months follow-up after disease onset,the proportion of patients who reached ACR pedi 50,70 in AR group were lower than the Non-AR group,while the cumulative glucocorticoid dose was higher in the AR group than that of those without AR [at 3 months 38％ vs 71％; 13％ vs 46％; (76±35) mg/kg vs (43±36) mg/kg,respectively; at 6 months 25％ vs 71％; 19％ vs 64％; 127±57 vs 67±58,respectively,all P＜0.05]; In the AR group,at the disease onset,3 and 6 months follow-up after disease onset,the scores of AR was positively correlated with DAS28(r=0.741,0.703,0.680,respectively; all P＜0.05).② In the prospective study:when SoJIA was relapsed,systemic feature score,the physician's and patients' /parents' general assessment on a l0 cm VAS,number of joints with restriction of movement,number of swollen joints,ESR,SF and CHAQ score were significantly elevated in the treatment group compared with the control group [3.8±1.5 vs 2.1±1.1; (5.6±1.5) cm vs (4.5±1.6) cm; (4.6±1.9) cm vs (3.1±1.5)cm; 3.9±1.9 vs 2.5±1.4; 2.4±0.9 vs 1.5±1.2; 92±27 vs 53±37; 565(339,1 192) μg/L vs 171(85,284) μg/L; 13(0.8,1.6) vs 0.7(0.5,1); respectively; P＜0.05].The improvement rate of the physician's and patients'/parents' general assessment on a 10 cm VAS,number of swollen joints,number of joints with restriction of movement,ESR and CHAQ score at the follow-up 3 months were higher in treatment group than the control group [71(55,86)％ vs 46(0,75)％; 67(45,81)％ vs 28(-4,62)％; 92(77,96)％ vs 70(27,88)％; 65(48,81)％ vs 0(-17,67)％; 100(46,100)％ vs 42(0,100)％; 67(49,85)％ vs 37(0,75)％; P＜0.05].At the follow-up 6 months,the improvement rate of ESR,patients'/ parents' general assessment on a 10 cm VAS,number of joints with restriction of movement and CHAQ score were higher than control group [94(85,96)％ vs 73(33,85)％; 89(65,99)％ vs 63(5,85)％; 100(100,100)％ vs 100(0,100)％; 91(69,100)％ vs 72(11,91)％; respectively,P＜0.05].Conclusion AR may exert an adverse influence on SoJIA.SoJIA patients who are treated with combined with AR may have better outcome than those who are only treated for arthritis.

Aim To explore the effects of hypertension on the contractibility of rat basilar artery and its inter-actions with the sodium pump activity.Methods The basilar artery was respectively isolated from Wistar and SHR rats,and the isometric tension of arterial rings was measured by Multi Myograph System-610M.The cont-ractibilities of arterial rings induced by KCl or 5-HT were compared between the basilar arteries of the two groups of rats to analyze the effect of hypertension on the cerebral vascular tension and the activity of sodium pump.Results In SHR rats,the concentration-re-sponse curves of the contraction of isolated basilar ar-tery rings induced by KCl and 5-HT were significantly shifted to right,and the relaxation of vascular tone in-duced by K+which was reintroduced from the external was attenuated compared with those in the WR.These results suggested that hypertension could significantly decrease the activity of the sodium pump and the con-tractile responses of KCl and 5-HT.OUA could con-tract the basilar artery in a concentration-dependent manner,and its concentration-response curve was opti-mally fitted by a two-site binding model:Kd was 1.7 ×10 -8 and 1.6 ×10 -5 mol·L-1,respectively.The results indicated that the two different function sodium pumps existed in the rat basilar artery:one with the high OUA affinity and the other with the low OUA af-finity.If the high and low affinity sodium pumps were inhibited by 5 ×10 -7 and 10 -4 mol · L-1 OUA,re-spectively,the concentration-response curves of KCl and 5-HT would shift to left in SHR rats but not in WR rats.It suggested that OUA could enhance the contrac-tion induced by KCl and 5-HT significantly,and a concentration-dependent effect was observed in the SHR vascular contraction induced by 5-HT (r =0.9393 ,P<0.05 ).When the two concentrations of OUA were applied,there was no significant difference in the shift left of the concentration-response curves in-duced by KCl in the SHR cerebral vessels.However, the marked difference was shown in the shift left in-duced by 5-HT.The results implied that only the high affinity sodium pump was involved in the contractile re-sponse of SHR cerebral vascular to KCl,whereas,the contractile response of SHR cerebral vascular to 5-HT was induced by both high and low affinity sodium pumps.Conclusion Hypertension could lower the contractile response of the basilar artery to vasocon-strictors,and the mechanism might relate to the de-creased sensitivity of the sodium pump induced by hy-pertension or the increased sensibility of the sodium pump to OUA.

Objective To find out a treatment with high remission rate,long living period,and a good quality of life for elderly patients with multiple myeloma.Methods All patients were recruited into a treatment group(treated with traditional Chinese medicine,routine chemotherapy,and thalidomide)and a comparison group(treated with traditional Chinese medicine and routine chemotherapy).Results The total effective rate of the treatment group was 71.4%,higher than the comparison group(38.5%),but showing 110 statistical difference(P=0.128＞0.05).Median survive time of two groups were 21.8 months and 12 months respectively,(P=0.001＜0.01).The survival rate of 3 years and 5 years were 28.6%,15.4%and 7.1%,0 in the two groups respectively,without significant difference(0.317,1.000,both P＞0.05).Conclusion The treatment group showed higher results in both complete remission rate(CR)and very good partial remission rate(VGPR)than the comparison group,demonstrating a better results in improving the patient's quality of life.The treatment group also had a higher value of the median survive time and the median progression-free surial time than the comparison group.The combined therapy of traditional Chinese medicine,routine chemotherapy and thalidomide is an ideal choice for both aged Patients or young MM patients who had no transplant conditions.

The paper is aimed to provide a novel index, named as multidimensional spatial triangular area, for the evaluation of the release-absorption correlation of multiple component traditional Chinese medicines (TCMs). The applicability of the method was demonstrated by the example data. The method and standard practice for evaluation of the release-absorption correlation for western medicines with single compound could not be applied to TCMs with multiple components. The release percentage or absorption percentage of the multiple components for TCMs at the sampling time was a point in the multidimensional space. The area of the triangle formed byt the sequential three points rrepresented the changing characteristics of the components' release and absorption kinetics. The side lengths of the triangle could be calculated from the spatial distances between each two of the sequential three points. Then the triangle area could be obtained by the side lengths. The in vitro release-in vivo absorption correlation of the multiple components could be represented by the correlation between the integrating values of the release triangle areas and that of the absorption triangle areas. The results of the examples indicated that the multidimensional spatial triangular area method could treat the multiple components in a holistic way, in line with the holism the hi he TCMs. Therefore, the multidimensional spatial triangular area method provided new methodology for the release-absorption correlation of the TCMs with multiple components.

Objective To evaluate the gastroesophageal reflux symptom in patients who underwent continuous ambulatory peritoneal dialysis (CAPD) and the efficacy of proton pump inhibitor (PPI) in treating gastroesophageal reflux. Methods Fifty-eight CAPD patients with good clinical and complete dialyzed eondition,who was admitted to the hospital between Jan. 2008 and July 2008, were inquired about their gastroesophageal reflux symptoms using reflux disease questionnaire (RDQ). The patients who had RDQ≥6 and <12 were received esomeprazole 20 mg daily, while those with RDQ≥12 were received esomeparzole 20 mg twice daily. RDQ score was reevaluated 4 weeks after treatment.Results The common symptom was regurgitation (64.70%), followed by acid reflux (52.9 %), non-cardic chest pain (47.1. %) and heart burn (17. 6%). After 4-week treatment, the RDQ was significantly decreased (P< 0. 05). But there was no difference in outcome of treatment between patients with RDQ≥ 12 and RDQ< 12 (P=0. 059). Conclusion The gastroesophageal reflux symptom in CAPD patients can be relieved by PPI administration, but a larger clinical trial is needed to evaluate the course and efficacy of treatment.

Objective To evaluate effects of glycemic control on refraction in diabetic patients.Methods Twenty newly diagnosed diabetic patients were included in this study. The random blood glucose,glycosylated hemoglobin A1c( HbA1c) levels, fasting C-peptide and postprandial 2 h C-peptide levels were measured before treatment. The patients with random blood glucose ≥ 12. 0 mmol/L and HbA1c ≥ 10. 0%were selected. Refraction, intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length, and axial length were measured on admission and at the end of week 1,2, 3 and 4 during glycaemic control. Results A transient hyperopic change occurred in all the patients receiving glycemic control with a mean maximum hyperopic changes of 1.6 D ( 0. 50 D ～ 3.20 D). There was a positive correlation between the magnitude of the maximum hyperopic changes and the HbA1 c levels on admission ( r = 0.84, P ＜ 0.05 ). There was a positive correlation between the magnitude of the maximum hyperopic changes and the daily rate of blood glucose reduction over the first 7 days of the treatment ( r = 0.53, P ＜ 0.05 ). There was no significant correlation between the magnitude of the maximum hyperopic changes and the levels of random blood glucose on admission. No significant correlation was observed between the maximum hyperopic changes and fasting C-peptide or postprandial 2 h C-peptide.There were no significant correlations between the magnitude of the maximum hyperopic changes and age,blood press, body mass index, triglyceride, total cholesterol, low-density lipoprotein or high-density lipoprotein. No significant changes were observed in the intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length and axial length during glycemic control. Conclusions Transient hyperopic changes occur after glycemic control in diabetic patients with severe hyperglycaemia. The degrees of transient hyperopia are highly dependent on HbA1c levels before treatment and the rate of reduction of glucose level over the first 7 days of treatment. This is probably due to the decrease of refractive power by lens hydration, not morphological change of lens.

BACKGROUND: The effect of Chinese traditional medicine 3'-meisoindigo as well as indimbin derivatives on normal immunocytes is less reported while it is used for antitumor.OBJECTIVE: To investigate the effect of 3'-meisoindigo on the proliferation of the splenocytes and thymocytes of C56BL/6 mouse.DESIGN, TIME AND SETTING: The randomized cytopathology observation was performed between August 2007 and January 2008 at Zhujiang Hospital of Southern Medical University, Guangzhou, Guangdong Province, China.MATERIALS: C57BL/6 mice, clean, male, 6-8 weeks old, weighing (20±2) g.METHODS: The thymus gland and the spleen of C57BL/6 mice were ground to get the single-cell suspension and cells were treated by 5, 10, 15, 20 and 25 μ mol/L 3'-meisoindigo,respectively. Cells without any drug treatment were used as blank control and cells treated by concanavalin A were used as positive control.MAIN OUTCOME MEASURES: Proliferation of splenocytes and thymocytes detected using MTT method; IL-12 activity in culture supematant detected using ELISA method; the cell cycle, apoptosis rate, cell death rate and intracellular reactive oxygen species level detected using flow cytometry; the mRNA level of bcl-2 and cdk2 detected using reverse transcription-polymerase chain reaction; the expression rate of Bcl-2, CDK2 and Bax detected using fluorescence microscope.RESULTS: After treating for 24 hours, 15, 20 and 25 μ mol/L 3'-meisoindigo can significantly inhibit the proliferation of thymocytes and splenocytes (P < 0.05) and the inhibition was dose-dependent and time-dependent. Cells resumed proliferation after removing the 3'-meisoindigo, although they had been treated by 25 μ mol/L 3'-meisoindigo for 72 hours. The secretion of IL-12 was markedly reduced in all 3'-meisoindigo groups versus control groups at each time point (P < 0.05). 15 μ mol/L 3'-meisoindigo could decrease the mRNA expression level of apoptosis-related protein bcl-2 and cyclin cdk2 gene, decrease the expression level of BCL-2 protein and CDK protein, increase Bax expression level, decrease Bcl-2/Bax ratio markedly and started apoptosis.15 μ mol/L 3'-meisoindigo arrested cells in the G2/M stage of the thymocytes and splenocytes, and intracellular reactive oxygen species level elevated dose-dependently and time-dependently.CONCLUSION: In certain concentration range, 3'-meisoindigo can reversibly inhibit the proliferation of thymocytes and splenocytes of C57BL/6 mouse and can inhibit IL-12 secretion in parallel, and start apoptosis.
