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.

BACKGROUND:It is unclear whether intramuscular injection of human umbilical cord mesenchymal stem cells wil increase regeneration of normal myocardial cells and play adverse effects on normal myocardium. OBJECTIVE:To observe the effects of intramuscular injection of human umbilical cord mesenchymal stem cells on expression of the myocardial ki-67, phh3 and cTnT in normal Wistar rats. METHODS:A total of 60 male Wistar rats were divided into six groups randomly:normal group, solution group, supernatant group, low concentration group, moderate concentration group, and high concentration group. These groups were intramuscularly injected different liquid, respectively, as fol ows:PBS, DMEM, the supernatant of human umbilical cord mesenchymal stem cells, human umbilical cord mesenchymal stem cells with amount of 0.25×105, human umbilical cord mesenchymal stem cells with amount of 1.0×105, human umbilical cord mesenchymal stem cells with amount of 4.0×105 . After 4 weeks, each rats received the second same intramuscular injections of human umbilical cord mesenchymal stem cells. Four weeks after the second injection, al rates were kil ed to obtain myocardial tissues which were fixed, embedded and sectioned. Final y, the ki-67, phh3 and cTnT expressions of the myocardium were detected by immunohistochemical technique. RESULTS AND CONCLUSION:In the normal group, negative expression of the ki-67 was observed in the caryon of myocardial cells, weak positive expression of the phh3 was observed in the caryon of myocardial cells, and positive expression of the cTnT was observed in the caryon of myocardial cells. Compared with the normal group, the expression of the ki-67, phh3 and cTnT in the myocardium had no significant difference among the other groups (F=1.076, 0.167, 0.300;P>0.05). Human umbilical cord mesenchymal stem cells or the supernatant of human umbilical cord mesenchymal stem cells via intramuscular injection have no effects on the expression of the ki-67, phh3 and cTnT in normal Wistar rats.
