Objective To investigate the effect of Daying-35 combined with metformin on ovulation induction after polycystic ovary syndrome, and to summarize the clinical experience.Methods Forty patients with polycystic ovary syndrome were treated with Daying-35 and treated as control group.Forty-five patients were treated with meta-35 combined with metformin and treated as observation group.After treatment, Level and ovulation induction, selected patients were our hospital in January 2016 to December 2016 between the treatment.Results There were no significant differences in T, FSH, LH, E2 and other hormone levels between the two groups before treatment.After treatment, the improvement of the treatment group was significantly more obvious;compared with the two groups of ovarian hyperstimulation syndrome and The rate of pregnancy was 47.5% in the observation group and 15.0% in the control group.The difference between the two groups was significant(P<0.05).Conclusion The effect of Daying-35 combined with metformin on ovulation induction after polycystic ovary syndrome was found to improve the progesterone level and improve the clinical status of the patients.Making the ovulation situation improved, improve the pregnancy rate, it is worth clinical reference.
ABSTRACT
Objective To study the effects of letrozole and clomiphene on the treatment of ovulation induction and the changes of reproductive hormone in the patients with polycystic ovary syndrome.Methods In Zhenhai District People's Hospital from January 2015 to December 2016, 100 cases with polycystic ovary syndrome as the research object in this study, were randomly divided into the control group and the experimental group, 50 cases in each group.The control group were treated with clomiphene, the experimental group were given letrozole combined clomiphene.The levels of reproductive hormones, ovulation rate and pregnancy rate were compared in the two groups.Results The ovulation rate was 90%, pregnancy rate was 46%, the numbers of follicles was(1.2±0.4).In the control group, the ovulation rate was 72%, the pregnancy rate was 22%, and the number of follicles was(2.2±0.5).The results showed that the ovulation rate and pregnancy rate in the experimental group were significantly higher than those in the control group, with statistical significance(P<0.05).The number of follicles in the control group was significantly higher than that in the control group, with statistical significance(P<0.05).There was no significant difference between the experimental group and the control group in the time of follicular maturation, which was not statistically significant.The levels of reproductive hormones in the experimental group were significantly lower than those in the control group, with statistical significance(P<0.05).Conclusion Letrozole combined clomiphene can improve the ovulation rate and pregnancy rate, reduce the reproductive hormone level, which has clinical application value.
ABSTRACT
BACKGROUND:As the high proliferation and low apoptosis of the bone marrow in polycythemia vera patients, hematopoietic stem cels transplanted into NOD/SCID mice can differentiate into erythroid cels, but whether hematopoietic stem cels transplantation could improve the hematopoietic function of aplastic anemia mice is not yet reported. OBJECTIVE:To investigate whether transplantation of bone marrow mononuclear cels with JAK2V617F mutation from polycythemia vera patients can influence hematopoietic reconstruction in aplastic anemia mice. METHODS:Severe aplastic anemia mouse models were established by using recombinant human interferon-γplus busulfan, and then, these mouse models were randomly divided into experimental group (n=10) and control group (n=10). Bone marrow mononuclear cels isolated from polycythemia vera patients with positive JAK2V617F mutation were transplanted into the mice in the experimental group via tail vein at 5 days after drug withdrawal.The same volume of normal saline was administered to the control group. Routine peripheral blood test, morphology of bone marrow cels, bone marrow biopsy, and percentage of CD45+ cels in the peripheral blood and marrow were determined at 14 days after transplantation. RESULTS AND CONCLUSION: At 14 days after transplantation, pancytopenia occurred in the experimental group, bone marrow smears showed scattered lymphocytes and hematopoietic progenitors, and bone marrow biopsy presented that hematopoietic tissues were reduced and a smal amount of granulocyte cels and erythroblasts could be seen, but megakaryocytes were rare. In contrast to the control group, there was no improvement in the hematopoietic function of mice in the experimental group. CD45+ cels were detectable in the peripheral blood and bone marrow in the experimental group, but not in the control group; and a higher percentage of CD45+ cels was measured in the bone marrow than in the peripheral blood of experimental group mice. Experimental findings indicate that bone marrow mononuclear cels from polycythemia vera patients with positive JAK2V617F mutation can be engrafted into aplastic anemia mice, but cannot improve the hematopoietic function of mice.
ABSTRACT
BACKGROUND:It is important to establish an ideal mouse model of severe aplastic anemia for investigating the mechanism and finding new therapies for aplastic anemia. OBJECTIVE:To establish a severe aplastic anemia mouse model by using recombinant human interferon-γand busulfan. METHODS:Sixty healthy Kunming female mice were randomly divided into two groups:model group (n=50) and control group (n=10). The model group was given recombinant human interferon-γat a dose of 1×104 U/d by intraperitoneal injection and busulfan at a dose of 18 mg/(kg·d) through stomach feeding for 7 days. The same volume of physiological saline was given to control group. Multi-parameters, including general condition, body weight, blood cellcount, morphology and biopsy of bone marrow were analyzed in two groups. RESULTS AND CONCLUSION:At day 7 after treatment, the weight, white blood cellcount, hemoglobin, blood platelet, reticulocyte count in model group were significantly lower than control group (P<0.05). Bone marrow smears and biopsy of model group showed marked reduction of bone marrow proliferation and increases of percentages of non-hematopoietic cellclusters and adipose tissue. The oil drop and fat vacuole were apparently seen in the model group. Severe aplastic anemia mouse model can be established by using recombinant human interferon-γand busulfan successful y, which is economic, stable and easy to operate.
ABSTRACT
Objective To evaluate the significance of platelet activation and the expression of inter-leukin (IL)-1β in patients with RA. Methods The activation of platelets and the expression of IL-1β in pla-telets in 50 RA patients(22 high-active, 28 mediate/low active ) and 30 normal controls were determined us-ing flow cytometry. Meanwhile, inflammatory indicators such as erythrocyte sedimentation(ESR), C-reactive protein (CRP) and DAS28 were also recorded. T test and correlation analysis were performed. Results The platelet activation in RA group(19.2±4.8) was higher than the control group(9.0±2.9)(t=10.5, P=0.001). The expression of IL-1β in platelets in RA group(41±11) was higher than control group(21±8)(t=9.01, P =0.000) .The platelet activation in high-active RA group(22 ±4) was higher than mediate/low active RA group(17 ±4)(t =3.96,P =0.001). The expression of IL-1β in platelets in high-active RA group(45 ±10) was higher than mediate/low active RA group (38 ±10)(t =2.329,P =0.024). The expression of IL-1β in platelets in RA group was positively correlated with the level of ESR、CRP and DAS28 (r value and P value were 0.576, 0.578, 0.618 and 0.000, 0.000, 0.000 respectively). Conclusion The platelets of patients with RA are activated and may suggest that IL-1β, which may associate with disease activity. Our research suggest that platelet may play a role in the inflammatory process of RA by secreting IL-1β.
ABSTRACT
Objective To compare the clinical efficacy and safety of two different conditioning regimens in nonmyeloablative autologous peripheral blood stem cell transplantation (NAST) for the treatment of systemic lupus erythematosus (SLE).Methods Different conditioning regimens were used in two groups:cytarabin combined cyclophosphamide in group 1 and ATG combined cyclophosphamide in group 2.Different recovery time of leucocytes,neutrophils and platelets in the two groups were compared.Statistical analysis were carried out by paired t-test.Results The mean time for peripheral leucocytes reaching 1.0×109/L,neutrophils getting up to 0.5×109/L,platelet raising to 100×l09/L and hemoglobin rising to 120 g/L in group 1 were [(7.2±1.3),(8.0±1.5),(10.5±1.4),(22.1±2.3)days] and [(10.4±2.1),(12.0±1.9),(19.3±2.1),(28.1± 2.4)] days in group 2.The difference was statistically significant (P＜0.01).CD4+ cell count and the ratio of CD4+/CD8+ of pre- and pro-NAST was changed.No significant differences were observed in the two groups.Conclusion For the sake of safety and hematopoietic reconstitution,we recommend cytarabin combined cyclophosphamide as the preferred conditioning regimen.
ABSTRACT
Objective To investigate the long-term efficacy of nonmyeloablative autologous peripheral blood stem cell transplantation(NAST) to cure refractory autoimmune disease(AD).MethodLong-term follow up of four cases of AD patients with NAST were summarized.The pretreatment regimen was intravenous injection of cytarabin (200 mg· kg-1· d-1 ) and cyclophosphamide (40 mg· kg-1· d-1).The therapeutic effect was evaluated by the change of symptoms and signs and long term complications.Changes of immune function were detected by flow-cytometry.ResultsFive cases of patients had been successfully engrafted.The average time for peripheral leucocytes count to reach 4.0×109/L was 12 days.It needed 10 days for platelets to return to 100×109/L and 22 days for hemoglobin to 120 g/L.Apparent remission of symptoms and signs was observed after transplantation.Lymphocyte subtypes analysis pre- and post- NAST showed that count of CD4+ and the ratio of CD4 +/CD8 + was returned to normal.One patient gave birth to a healthy baby four years after transplantation.Three female patients returned tonormal life. Conclusions Compared with classical myeloablative stem cell transplantation,NAST has a rapid hematopoietic recovery and good long-term therapeutic effect in AD.The quality of life in AD patients treated with NAST is higher than those treated with myeloablative hematopoietic stem cell transplantation.
