Objective To investigate the changes in serum leptin and adiponectin levels and their significance in patients with chronic hepa-titis B virus (HBV)infection.Methods One hundred and twenty -five patients with chronic HBV infection (44 HBeAg -positive cases, 31 HBeAg -negative cases of chronic hepatitis B,23 chronic HBV carriers,and 27 inactive HBsAg carriers)were recruited in the present study.Fifty -five healthy people served as the control group.Blood samples were collected at 8 to 9 AMof the next morning after overnight fasting.Blood glucose,blood lipids,renal and liver function parameters,fasting insulin,serum HBV markers,and HBV DNA concentration were determined,and HOMA -IR was calculated.Serum levels of leptin and adiponectin were measured by ELISA.Continuous data were expressed as mean ±SD,and Student′s t -test,analysis of variance,linear regression analysis,and multiple regression analysis were ap-plied in the analysis of all experimental data.Results There were no significant differences in serum levels of leptin and adiponectin be-tween patients with chronic HBV infection and the control group (P =0.480;P =0.321),even after stratification by gender (males:P =0.210 /0.895;females:P =0.404 /0.066).After patients with chronic HBV infection were divided into subgroups by HBeAg status,HBV DNA,or ALT level,there were no significant differences in serum levels of leptin and adiponectin between groups (leptin:P =0.820 /0.296 /0.212;adiponectin:P =0.268 /0.760 /0.224).Conclusion For patients with chronic HBV infection,infection status and viral replication level are not significantly correlated with serum levels of leptin and adiponectin.

Objective:To prepare and optimize sorafenib-Eudragit RS nanoparticles( S-E üPs)and investigate the physicochemi-cal properties. Methods:S-E üPs were prepared by a solvent-nonsolvent method. Single factor experiments were used to research the effect of solvent,stabilizer type,carrier ratio and the proportions of water phase and organic phase on the physicochemical properties of S-E üPs. S-E üPs were evaluated by the particle size,zeta potential and morphology,and the in vitro drug release of S-E üPs was studied using dialysis technology. Results:The mean size was(86. 72 ± 3. 71)nm,the PDI and zeta potential was(0. 20 ± 0. 032)and (36. 6 ± 0. 3)mV,respectively,S-E üPs showed spherical shape with uniform distribution. The drug release in vitro was accorded with a Weibull equation. Conclusion:The solvent-nonsolvent method is appropriate for the preparation of S-E üPs. The nanoparticles have small particle size,uniform distribution,regular morphology and significant sustained-release property.

Adenosine receptors (AR) play an important role in the regulation processes for body temperature and vigilance states. During our previous studies, we noticed that aminophylline (a non-selective, blood-brain-barrier penetrably AR antagonist) could attenuate the effects of YZG-330 [(2R,3S,4R,5R)-2-(hydroxymethyl-5-(6-(((R)-1-phenylpropyl)amino)-9H-purin-9-yl)tetrahydrofuran-3, 4-diol] on lowering the body temperature. Hereby, we focused ourselves on the character of thermal regulation effect of YZG-330 in mice and tried to specify the receptor subtype via giving typical adenosine receptor antagonists. The results showed that both of the magnitude and lasting time of the effect that YZG-330 played on decreasing body temperature are in a dose-dependent manner: within the next 3 hour after intragastric administration (ig) of 0.25, 1 or 4 mg . kg-1 YZG-330, the extreme values on body temperature decreasing were (1.2 ± 0.3) °C, (3.6 ± 0.4) °C (P<0.001) and (7.4±0.5) °C (P<0.001), separately; whereas the duration that body temperature below 34 °C were 0, (10±5) and (153±4) min, separately. Adenosine A1 receptor (A1R) antagonist (DPCPX) could effectively reverse YZG-330's effect on decreasing body temperature, with intraperitoneal administration of DPCPX (5 mg . kg-1) 20 min prior than YZG-330 (4 mg.kg-1, ig), the extreme value on body temperature decreasing was (3.5 ± 0.7) °C (P<0.001), the duration that body temperature below 34 °C was (8±6) min (P<0.001). However, adenosine A2a receptor antagonist, SCH-58261, did not show any influence on the effects of YZG-330 at all. Combined with the fact that 8-SPT (a non-selective, blood-brain-barrier impenetrably AR antagonist) did not reverse the effect of YZG-330, we come to the conclusion that central-adenosine A, receptor plays a significant role on the thermal regulation effect of YZG-330.

OBJECTIVETo study the possible mechanisms of chronic nonbacterial prostatitis (CNP) pain.

METHODSCNP models were established in male Wistar rats by the autoimmune method. Then the paw withdrawal threshold (PWT) was detected using the Von Frey filament, prostate pathological examination was conducted, the expressions of substance P (SP) and transient receptor potential vanilloid 1 (TRPV1) in the prostate tissue and L5-S2 spinal segments were determined by immunohistochemistry and their correlations were analyzed.

RESULTSCompared with the control group, the CNP model rats showed markedly decreased PWT (P < 0.05) and obvious inflammation in the prostate tissue, with significant differences in the scope of lesion and interstitial lymphocyte infiltration (P < 0.05). The expressions of SP and TRPV1 in the prostate and spinal cord dorsal horn L5-S2 were remarkably upregulated in the models as compared with the control rats (P < 0.05). However, the expression of SP in the prostate was not correlated with that in the spinal cord (r = 0.099, P = 0.338), nor was that of TRPV1 (r = 0.000, P = 0.5).

CONCLUSIONSP and TRPV1 were involved in the formation and persistence of pain in CNP rats through their upregulated expressions in the L5-S2 spinal segments.

OBJECTIVETo explore the possible pain mechanism of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

METHODSThe models of CP/CPPS were established in male Wistar rats by the autoimmune method. The paw withdrawal threshold (PWT) was detected using Von Frey filament. The expressions of the substance P and c-fos in the prostate and spinal L5-S2 segments were determined by immunohistochemistry followed by analysis of their correlation with CP/CPPS.

RESULTSCompared with the control rats, the CP/CPPS models showed significantly decreased PWT (P < 0.05), remarkable prostatic inflammation, enlarged scope of lesions, and obvious interstitial lymphocytic infiltration (P < 0.05). Both the expressions of substance P and c-fos were markedly elevated in the prostate and spinal dorsal horn (L5-S2) of the rat models (P < 0.05), but the expression of substance P in the prostate exhibited no correlation with that in the spinal cord (r = 0.099, P = 0.338), nor did that of c-fos (r = 0.027, P = 0.454).

CONCLUSIONThe upregulated expressions of substance P and c-fos in the spinal cord L5-S2 sections may be associated with the pain mechanism of CP/CPPS.

Objective To explore the feature and the optimal treatment of kidney stones in children associ-ated with infant formula which had been aduherated with melamine.Method Total of 47 cases of urinary stone and 31 cases of acute renal failure caused by urinary multiple obstruction in children associated with infant formula which had been adulterated with mlelamine in Beijing Children's Hospital University of Medical Science,form Jan-uary to November,2008 were retrospectively analyzed.Results Infant formula which had been adultemted with melamine may lead to kindey stones in 15 days.The mean age was 11-month and the ratio of male to female was 2.6:1.The kindey stones were usually multiple and mostly located either in the ureteropelvic junction or all through the ureter.In the view of the renal function resuming duration,there was no statistic difference among the acute renal failure group,operation group and the conservative group(P=0.683～0.846).In children with uri-nary obstruction and acute renal failure,hemedialysis or peritoneal dialysis was performed.83.9%were relieved by posting catheter through panedoseope and blood purification.100% of the patients resumed normal renal func-tion.81.3% of the patients without acute renal failure had recovered after conservative therapies such as infusion.Conclusions The patients associated with infant formula which had been adulterated with melamine were Usually little infants.Male were more vulnerable than female.Most of them had recovered smoothly and the renal function resumed normal after effcient therapies.
