Objective By making models of premature animal,explores the effects of dexamethasone on the brain development of premature rats and its mechanisms.Methods Eighteen SD rats were randomly divided into high-dexamethasone(H-Dex) group,low-dexamethasone (L-Dex) group and normal saline(NS) control group,with 6 rats in each group.The pregnant rats in L-Dex group were injected with dexamethasone [0.1 mg/(kg·d)] from 16 to 18 days of pregnancy,while the pregnant rats in H-Dex group were injected with dexamethasone [0.5 mg/(kg· d)] ; the pregnant rats in NS control group were injected with 0.9％ NaCl of the same volume.All of the fetal rats were received after administrating caesarean operation on the day 19 of pregnancy.Rats were sacrificed at the directed time and brain tissue was prepared.Histological feature and the water content of the brains were observed.Level of apoptosis was measured by flow cytometry.The expressions of myelin basic protein (MBP) and interleukin(IL)-1β in brain tissue homogenate were detected by ELISA.Results (1) The brain water contents of rats in H-Dex group,L-Dex group and NS control group were (85.94 ± 0.54) ％,(86.08 ± 1.01) ％,(86.94 ± 0.82) ％.Compared with NS control group,the water contents of Dex group were lower (P ＜ 0.05).(2) Glial cells of brain cortex in L-Dex group and H-Dex group were more mature than in NS control group,and the changes in H-Dex group was more significant.(3) The expressions of MBP in brain tissue of H-Dex group,L-Dex group and NS control group were (5.73 ± 1.06) μg/mg,(5.46 ±0.77) μg/mg and (2.42 ±0.52) μg/mg.Compared with NS control group,Dex group was higher(P ＜0.05).While the expressions of IL-1β in brain tissue of H-Dex group,L-Dex group and NS control group were (249.05 ± 11.29) pg/g,(257.47 ± 9.33) and (292.66 ± 21.51) pg/g.Compared with NS control group,Dex group was lower(P ＜ 0.05).There was no significant difference between H-Dex group and L-Dex group(P ＞ 0.05).(4) The level of apoptosis in H-Dex group,L-Dex group and NS control group were (18.07 ± 1.63) ％,(6.88 ± 0.47) ％ and (2.00 ± 0.32) ％.Compared with NS control group,the level of apoptosis in Dex group was higher(P ＜0.05),and H-Dex group was higher than that in L-Dex group.Conclusion (1) Using dexamethasone prophylactic could promote the development of glial cells,reduce the water content,increase the expressions of MBP,and decrease the expressions of IL-1β in brain tissues.It indicates that dexamethasone may play a major role in maturation of fetal brain.(2) Using dexamethasone prophylactic could increase the amounts of the apoptosis cells,and this effect is dose-dependent.It indicates that dexamethasone may have a negative effect on the fetal brain and suggestes that using dexamethasone in premature infant should be cautious,and if it has to,using a lower dose.

OBJECTIVETo investigate clinical effects of strategy by stages for preventing respiratory complications of patients with acute cervical spinal cord injury (ACSCI).

METHODSFrom September 2009 to May 2013,the clinical data of 91 patients with ACSCI underwent surgery were retrospectively analyzed. Among the patients, 42 patients were divided into in-stages group, including 30 males and 12 females with an average age of 50 years old (ranged 28 to 76) which were treated with strategy by stages for preventing respiratory complications; others 49 patients which were not treated with the strategy regarded as control group, including 38 males and 11 females with an average age of 47 years old (ranged 30 to 77). All of them had definite history of trauma, and were admitted to orthopaedics within 48 h after trauma. In in-stages group, respiratory muscle strength training, high-dose ambroxol using and other treatment were performed to prevent respiratory complilcations according to preoperative, intraoperative and postoperative stage. While in control group, there were no systematic and effective measures utilized. Chi-square test was used to evaluate the difference for respiratory complications rate, the rate of tracheostomy or intubation and mortality caused by the respiratory complications between two groups.

RESULTSTen patients developed with respiratory complications in in-stages group (7 patients with pneumonia, 1 with atelectasis and 2 with respiratory failure), among which 3 patients underwent tracheostomy or intubation. In control group, 24 patients developed with respiratory complilcations (15 with pneumonia,3 with atelectasis and 6 with respiratory failure), among which 11 patients underwent tracheostomy or intubation. There was significant difference between two groups (χ2 = 6.12, 4.07; P = 0.013, 0.044). Five patients died because of respiratory complications, one case were in in-stages group and 4 in control group. There was significant difference between two groups (χ2 = l.39, P = 0.238).

CONCLUSIONThe strategy by stages is an effective method for preventing respiratory complications of ACSCI and can reduce the respiratory complications rate and improve the prognosis of respiratory complications.

OBJECTIVETo compare the effect of combined therapy of Zhenqi Zhuanyin Decoction (ZQZYD) and timely intrauterine insemination (IUI) with that of using ZQZYD and IUI separately in treating patients of sterility with positive anti-sperm antibody (AsAb).

METHODSOne hundred and three patients were randomly divided into 3 groups, 34 patients in Group A treated with combined ZQZYD and IUI, 34 in Group B treated with ZQZYD alone and 35 in Group C treated with IUI alone. The negative conversion rate of AsAb, pregnancy rate in patients, pregnancy rate in AsAb converted patients, as well as changes of TCM Syndrome and T-lymphocyte subsets were observed.

RESULTS(1) The negative conversion rate of AsAb in the 3 groups was 76.47% (26/34), 82.35% (28/34) and 8.57% (3/35) respectively. (2) In Group A, the pregnancy rate was 41.18% (14/34), pregnancy rate in AsAb negative converted patients was 50.0% (13/26); in Group B, the respective criteria was 20.59% (7/34) and 21.43% (6/28) respectively; and in Group C, the pregnancy rate was 11.43% (4/35). The pregnancy rate in Group A was significantly higher than that in Group B or C (P < 0.01). (3) The effective rate on TCM Syndrome in Group A and B was 88.23% and 91.18% respectively (P > 0.05). (4) In Group A and B, CD4 decreased, CD8 increased and CD4/CD8 ratio decreased after treatment, which were significantly different from those before treatment and in Group C after treatment (P < 0.05).

CONCLUSIONCombined therapy of ZQZYD and IUAI shows a better effect in treating infertility with positive AsAb than that by ZQXYD or IUI alone.

OBJECTIVETo observe the clinical effect of Erzhi Tiangui Recipe (ETR), a traditional Chinese recipe for strengthening Shen and nourishing Tiangui, in improving the ovarian reactivity in elderly sterile women.

METHODSSixty-six elderly sterile women receiving in vitro fertilization pre-embryo transfer (IVF-ET) were randomly divided into two groups: the ETR group treated with ETR plus follicle stimulating hormone (FSH) and the control group treated with FSH alone, 33 cases in each group. Changes of symptoms and the relative parameters were observed, including the dosage of FSH used, the serum hormone levels at different periods, endometrium thickness and arteriopalmus of uterus and ovary on the day of HCG injection, follicle number, follicular oocyte number, mature follicular oocyte rate and fertilization rate, prime embryo rate, and pregnancy rate. Moreover, the correlation of the symptom score of colpoxerosis (CR2) and serum estradiol (E2) level was analyzed after treatment (on the HCG injection day).

RESULTSSymptoms of Shen qi-yin deficiency were improved significantly in the ETR group, with the improvement better than that in the control group (P < 0.05). The total and daily FSH dosage in the ETR group were lower than those in the control group, showing significant difference between the two groups (P < 0.05). The effects were better in the ETR group than those in the control group in increasing serum E2 and endometrium thickness on the HCG injection day, and also in elevating the follicular oocyte number, the mature oocytes rate, the fertilization rate, and the prime embryo rate (all P < 0.05). CR2 analysis showed low negative correlation in both groups (r = -0.369 in the ETR group and r = -0.425 in the control group), suggesting E2 could be one of the factors but not the only factor for influencing colpoxerosis. And the score of colpoxerosis was lower in the ETR group after treatment than that in the control group (t = 2.422, P < 0.05).

CONCLUSIONETR combined with FSH can obviously reduce the dosage of FSH used, improve ovarian reactivity and pregnancy rate, and improve the quality of oocytes, the mechanism is possibly related with its effects in improving ovarian reactivity elevating blood estrodiol and regulating the hypothalamus-pituitary-ovary axis (HPOA).
