Objective To study the effects of low-temperature environment on the contents of serum protein, serum calcium and blood sugar in rabbits. Methods The rabbits were divided into three experiment groups, which were exposed to environment at 2, -4 and -6 ℃ respectively and one control group exposed to environment at room temperature of 16 ℃. After exposure for 30～60 min, the peripheral blood samples were collected from rabbits for determination of levels of blood sugar, serum protein and calcium. The anal temperatures and ECG of rabbits were also examined. Results The levels of blood sugar, serum protein and calcium of rabbits in experiment groups decreased with the decrease of environmental temperatures, and revealed significant differences compared with those of control group(P

Objective To study the expression of vascular endothelial growth factor(VEGF), microvessel density (MVD) and the relationship among angiogenesis,proliferation,and apoptosis in colorectal cancer (CRC). Methods Expression of VEGF mRNA was evaluated by semi quantitative RT PCR in 52 CRC samples and 48 adjacent normal colorectal tissue samples. The PCR product was sequenced to verify the desired results. Expressions of VEGF protein, MVD, proliferating index (PI), and apoptotic index (AI) were detected by immunohistochemical methods in 52 human CRC. Results Expression of VEGF mRNA was detected in a significantly greater proportion of colorectal carcinoma samples than that adjacent normal colorectal tissues (76.9% vs. 52.1%; P 0.05). The expression of VEGF protein was positively correlated with PI ( r =0.409, P 0.05). Conclusions VEGF may play an important role in the angiogenesis of colorectal carcinoma and cell proliferation, but may not directly correlate with cell apoptosis.

OBJECTIVETo assess Microcystin LR (MCLR)-induced acute toxic effects in male Sprague-Dawley rats.

METHODSThe rats were injected with MCLR intraperitoneally in different doses for different days. The organs and serum with rats were collected at 1 and 7 days after injection, and 7 days after the final injection (total 14 days). Pathological and enzymatic changes were observed.

RESULTSThe rats injected with 122 microg/kg MCLR showed myocardial cells damage including pyknosis, plasma dissolve and myofibrilla (pls check with dictionary) necrosis in the heart muscles after 24 hours. At the same time, the activities of serum glutamate-oxaloacetate transaminase (GOT), lactate dehydrogenase (LDH) and creatine phosphonase (CPK) were higher than these in the other groups (P < 0.01). The kidney was also damaged, kidney cell degeneration, and the increase of blood creatine (BCr) and blood urea nitrogen (BUN) were also seen. In liver pathological study, liver cell hemorrhage, degeneration and/or necrosis was observed. In serum the activities of glutamate-pyruvate transaminase (GPT), alkaline phosphatase (LDH) and GOT were higher than these in the other groups (P < 0.01).

CONCLUSIONThese results suggested that MCLR can injure the heart, kidney and the liver in SD rats, and there is a dose-response relationship between MCLR and the toxic effect.

Objective:The clinical characteristics of pregnant women with HELLP syndrome before and after delivery and the risk factors of pregnancy outcomes were analyzed.Methods:A retrospective analysis was con-ducted on 126 cases of HELLP syndrome admitted to The Affiliated Suzhou Hospital of Nanjing Medical University from January 2010 to May 2021,divided into prenatal HELLP group[n=108,98 cases with severe preeclampsia(SPE)]and postpartum HELLP group(n=18,15 cases with SPE),to compare the differences in clinical charac-teristics and pregnancy outcomes between the two groups with the different onset time and whether they were complicated with SPE.Results:①Compared with the postpartum HELLP group,the prenatal HELLP group had higher systolic blood pressure in the third trimester of pregnancy,shorter time from preeclampsia to HELLP syn-drome,higher liver function abnormalities,lower platelet counts,and lower 24-hour urinary protein,with statistically significant differences(P＜0.05).There was no statistically significant differences in adverse pregnancy outcomes and neonatal prognosis between the two groups(P＞0.05).②When combined with SPE,the antenatal HELLP group had a shorter interval from preeclampsia to HELLP syndrome,lower platelet counts,and higher liver en-zymes than the postpartum HELLP group,with statistically significant differences(P＜0.05).③There was no sig-nificant difference in clinical features between the antenatal HELLP group and the postpartum HELLP group when not complicated with SPE(P＞0.05).Conclusions:There is only one difference between prenatal and postnatal HELLP syndrome in terms of the speed of disease progression,the time taken from preeclampsia to HELLP syn-drome,and both can lead to serious maternal and neonatal complications,which should be identified early in clini-cal practice.
