Chinese Journal of Laboratory Medicine 2012;35(6):493-496
Diabetes is a worldwide epidemic disease in the twenty-first century.The most danger of diabetes is its complications which are the major cause of morbidity and mortality in diabetic patients.The development and progression of diabetes complications are directly associated with blood glucose levels,Hemoglobin A1c is not only the gold standard for the long-term blood glucose control of diabetic patients,but also the World Health Organization (WHO) recommended diagnosis of diabetes.Thus,a question has been raised:how to improve the comparability of hemoglobin A1c results meet clinical needs? At least four points should be taken in determining hemoglobin A1c:(1)Understand the interference factors; (2)Choose scientific and practical methodologies; (3)Standardized operation; (4)Regularly monitor the quality of testing results.

Chinese Journal of Primary Medicine and Pharmacy 2006;0(05):-
Objective To explore the characteristic of disease cause,clinical diagnosis and main tactics of therapy in the temporary liver function damage that is not caused by common hepatitis virus.Methods 573 cases of liver function damage of pediatrics ward in the past 2 years were analyzed and studied about the value of the liver protecting therapy.Results In all 573 cases surfered from liver function damage,418 cases were caused by respiratory infection,accounted for 10.8% of the total patients of the same desease in the same period,101 cases of acute infection of the upper respiratory tract,accounted for 15.6%;54 cases of newborn baby's disease,accounted for 3%.The slight degree damage occupied 492 cases,whether or not taking protecting the liver cures,it hadn't the notable difference on the statistics.The middle to heavy degree damage occupied 135 cases,whether taking protecting the liver cures or not,it had the notable nature difference on the statistics.Conclusion Many common diseases of pediatrics can cause temporary liver function damage.Clinician should take attention to this.It is not necessary to carry out liver protecting therapy in the slight damage cases;And the liver protecting therapy can contribute to the recovering of liver function of the middle to heavy degree damage.

BACKGROUND:Different local anesthetic solutions for tumescent liposuction are necessary and have a certain effect on the biological characteristics of human adipose stem cels.
OBJECTIVE:To explore the effect of different tumescent local anesthesia on the proliferation and differentiation of human adipose stem cels culturedin vitro.
METHODS: Passage 3 human adipose stem cels were intervened by different tumescent local anesthesia (bupivacaine, ropivacaine, lidocaine). Cels cultured in low-glucose DMEM served as controls. Proliferation ability, lactate dehydrogenase activity in the supernatant and percentage of cels under adipogenic differentiation were detected.
RESULTS AND CONCLUSION:After intervention for 1, 2, 3, 4, 5 days, the supernatant lactate dehydrogenase activity in the bupivacaine, ropivacaine, lidocaine groups was significantly higher than that in the control group (P < 0.05), and moreover, the lactate dehydrogenase activity in the bupivacaine group was significantly higher than that in the ropivacaine group and lidocaine group (P < 0.05). The absorbance value of human adipose stem cels was lower in the bupivacaine, ropivacaine, lidocaine groups than the control group (P < 0.05) as wel as lower in the bupivacaine group than the ropivacaine and lidocaine groups (P < 0.05). There was no significant difference in the percentage of cels under adipogenic differentiation between groups (P > 0.05). Overal, these findings indicate that different tumescent local anesthesia (bupivacaine, ropivacaine, lidocaine) can al inhibit the proliferation of human adipose stem cels, but have no certain effects on the adipogenic differentiation.

Objective To evaluate the clinical effect of different doses of leuprorelin acetate in in vitro fertilization-embryo transfer(IVF-ET).Methods From January 2011 to December 2011,the data of 268 patients undergoing IVF and (or) intracytoplasmic sperm injection (ICSI) in Reproductive Medical Center,Clinical College of PLA,Anhui Medical University were studied retrospectively.All the patients were divided into three groups based on with long protocol and controlled ovarian stimulation (COH) including 83cycles with 1.25 mg of leuprorelin in low dose group,68 cycles with 1.88 mg of leuprorelin in high dose group,117 cycles with 1.25 mg of diphereline in control group.The serum follicle stimulating hormone (FSH),luteinizing hormone (LH),estradiol (E2) and progesterone (P) before gonadotropin (Gn)administration on the days 3-5 of the menstrual cycle and on the day of hCG administration were detected,the dose and duration of Gn,number of oocytes retrieved,number of mature oocytes,the rates of fertilization,embryo cleaved,good-quality embryos clinical pregnancy and early miscarriage were compared among three groups.Results There were no significant differences in age,the level of LH and P on the day of hCG administration among three groups (P > 0.05).The level of FSH was (3.8 ± 1.6) U/L in low dose leuprorelin group,(3.1 ± 1.4) U/L in high dose of leuprorelin group and (2.4 ± 1.3) U/L in diphereline group before Gn administration,which reached statistical difference (P < 0.05).The mean length of Gn stimulation were (9.8 ± 1.7) days in low dose leuprorelin group,(10.5 ± 1.8) days in high dose of leuprorelin group and (11.1 ± 1.4) davs in diphereline group,which reached statistical difference (P <0.05).The mean dose of Gn was (24 ± 7) in low dose of leuprorelin group,which was significantly higher than (27 ± 9) in high dose of leuprorelin group and (28 ± 7) in diphereline group (P < 0.05).The level of LH was (2.7 ± 1.6) U/L in low dose of leuprorelin group and (2.2 ± 1.0) U/L in diphereline group before Gn administration,which reached statistical difference(P < 0.05).The cancel cycles were 5 in low dose of leuprorelin group,4 in high dose of leuprorelin group and 7 in diphereline group.The number of ovum was (14 ±7) low dose of leuprorelin group,(13 ±6) in high dose of leuprorelin group,(14 ±6) in diphereline group.The rates of fertilization was 66.26% (758/1144)in low dose of leuprorelin group,67.01% (589/879) in high dose of leuprorelin group and 68.54% (1111/1621) in diphereline group,the rates of goodquality embryos was 64.22% (472/735) in low dose of leuprorelin group,60.50% (340/562) in high dose of leuprorelin group and 59.59% (640/1074) in diphereline group,clinical pregnancy was 49% (38/78) in low dose of leuprorelin group,42% (27/64) in high dose of leuprorelin group and 50% (55/110) in diphereline group,early miscarriage was 18% (7/38) in low dose of leuprorelin group,15% (4/27) in high dose of leuprorelin group and 15% (8/55) in diphereline group,which did not show significant differences (P >0.05).Conclusions Both 1.25 mg and 1.88 mg leuprorelin acetate could obtain good downregulation effect and clinical outcomes.1.25 mg leuprorelin acetate could decrease patient's costs by reducing Gn dose and duration.
