The in-vitro fertilization and embryo transfer technique has been widely applied in human insemination. The rate of successful insemination is gradual y rising, and the in-vitro fertilization directly determine the insemination outcome.
OBJECTIVE:To evaluate the difference between the two common using insemination methods, microdrop and open, in in-vitro fertilization and embryo development.
METHODS:A randomized study was conducted to compare microdrop and open insemination methods among non-male factor patients undergoing in-vitro fertilization and embryo transfer. A total of 1 175 cases were enrol ed in the research. There were 573 cases in the microdrop group, and 602 cases in open insemination group. The fertilization rate and embryo development in the two groups were compared.
RESULTS AND CONCLUSION:The fertilization failure rate [total fertilization failure rate+low fertilization rate (<25%oocytes fertilized)] in the microdrop insemination group was higher than in the open insemination group (11.9%, 3.3%, P<0.001), while the good quality embryo rate and pregnancy rate did not differ significantly between the two groups (al P>0.05). The open insemination method is a simple insemination method with a lower fertilization failure rate. As the fertilization is a highly complicated process involving many extrinsic and intrinsic factors, further study is needed to confirm the effects of the two insemination methods on in-vitro fertilization outcome.

OBJECTIVE:
To investigate HLA-A, -B, and -DRB1 gene polymorphism in the Miao ethnic group in Hunan, China.
METHODS:
PCR-sequence specific oligonucleotide probes (SSO) reverse flow chip method was used to type HLA-A, -B, and -DRB1 genes of 154 unrelated healthy Miao ethnic individuals in Hunan. The allele and haplotype frequencies were calculated and compared with other populations in China.
RESULTS:
A total of 10 HLA-A, 25 HLA-B, and 13 HLA-DRB1 alleles were observed in the population. The higher frequency alleles included A 11(38.96%), A 02(27.27%), A 24(18.83%), B 40(60)(17.53%), B 46(13.96%), B 15(75)(11.69%), DRB1 09(15.26%), DRB1 12(15.26%), DRB1 15(15.26%), and DRB1 04(12.66%). The most frequent haplotypes were A11-B60(9.60%), A2-B46(9.27%), A11-B75(9.22%), B75-DR12(6.31%), A11-DR12(9.62%), A11-DR4(9.07%), A11-DR15(6.69%), A11-B75-DR12(5.43%), A11-B60-DR4(4.24%), and A2-B46-DR9(3.71%). Compared with other populations in China, HLA gene polymorphism of Hunan Miao population was close to that of southern population.
CONCLUSION
HLA loci are highly polymorphic in the Miao population of Hunan, and their distribution has the character of South China population.

OBJECTIVETo determine the relation between the change of immunology indexes of serum and the occurrence of anaphylaxis in patients induced by Qingkailing injection, and to establish the method of detection of the type of anaphylaxis in patients induced by traditional Chinese medicine (TCM) injection.
METHODIn a prospective nested case-control study, we compared the concentration of IgE, IgG, IL-2, IL-4 of 20 cases in anaphylaxis induced by Qingkailing injection with those from 60 matched controls who remained normal after the using Qingkailing injection. The correlation between the change of IgE, IgG, IL-2, IL-4 of serum and the occurrence of anaphylaxis in patients induced by Qingkailing injection was determined, and we also evaluate the clinical values of IgE, IgG, IL-2, IL-4 of serum in diagnosis of anaphylaxis in patients induced by Qingkailing injection by Binary-Logistic regression analysis.
RESULTThe concentrations of IgE, IgG, IL-2, IL-4 of serum of 20 cases were significantly higher than those in controls (P < or = 0. 05). The concentrations of IgE, IgG, IL-2, IL4 of serum of 20 cases after the treatment with Qingkailing injection were significantly higher than those before the treatment with Qingkailing injection (P < or = 0.05). The Exp(B) of IgE, IgG, IL-2, IL-4 were 22. 018 (95.0% CI for EXP was 3.268-310.831), 11.271 (95.0% CI for EXP was 1.91-3.024), 23.612 (95.0% CI for EXP was 3.012-421.187), 16.486 (95.0% CI for EXP was 1.233-205.413), respectively.
CONCLUSIONThe allergic reaction caused by Qingkailing injection may be due to type I allergic reactions; The presence of IgE, IgG, IL-2, IL-4 can serve as clinical evaluation indicators in evaluation the damage degree of immune system caused by anaphylaxis in patients induced by Qingkailing injection. Cytokines are more likely to become the effective evaluation index in diagnosis of anaphylaxis in patients induced by TCM injection.

OBJECTIVETo re-evaluate the effects of different treatments to prevent from phlebitis induced by Chansu injection.
METHODPatients treated with Chansu injection were divided randomly into 4 groups with 50 per group, control group, the magnesium sulfate group, phentolaminum group, and anisodamine group. Patients in the control group only received the routine nursing treatment, and patients in the various experiment group received different interventions. The comparison was made in the morbidity and the starting time of occurrence of phlebitis, the severity of pain, duration of pain.
RESULTThe morbidity of phlebitis was 8%, 8%, 6% respectively. The starting time of phlebitis occurrence was (21 +/- 9.31) , (22.34 +/- 10.15), (20.19 +/- 11.23) h, respectively. The NRS of pain was (4. 15 +/- 1.03), (3.26 +/- 1.17), (4.32 +/- 1.36), respectively. The duration time of pain was (4.05 +/- 1.21), (3.37 +/- 1.17), (3.19 +/- 1.67) d, respectively. In control group, the morbidity of phlebitis, the starting time of occurrence of phlebitis, the severity of pain, duration of pain was 24%, (17 +/- 6.32) h, (6.58 +/- 1.29), (5.32 +/- 1.12) d, respectively. As compared with the control group, a significance difference was found between every group in three test groups and control group respectively (P<0.05).
CONCLUSIONThe morbidity and the starting time of occurrence of phlebitis, the severity of pain, duration of pain was significantly reduced respectively by external appication of magnesium sulfate, anisodamine, and intravenous drip infusion of phentolaminum.
