OBJECTIVE:To observe analgesic effect and safety of ketorolac tromethamine combined with butorphanol tartrate in the treatment of acute pain after fracture surgery. METHODS:76 acute pain patients after fracture surgery were selected and ran-domly divided into control group and observation group,with 38 cases in each group. Control group was given Ketorolac trometh-amine injection 30 mg,ivgtt,and then 2 ml/h,0.5 mg/kg,ivgtt;observation group was additionally given butorphanol tartrate 10 mg,ivgtt,on the basis of control group. Pain degree was evaluated with VAS before and 10 min,1,2,4 and 6 h after treatment, and the occurrence of ADR was observed in 2 groups. RESULTS:10 min,1,2,4 and 6 h after treatment,VAS score of 2 groups were significantly lower than before,with statistical significance(P<0.05);6 h after treatment,VAS score of observation group was significantly higher than that of control group,with statistical significance (P<0.05);there was no statistical significance in VAS score between 2 groups 10 min,1,2 and 4 h after treatment (P>0.05). The incidence of ADR in observation group (5.26%)was significantly lower than in control group(21.05%),with statistical significance(P<0.05). CONCLUSIONS:Com-pared with ketorolac tromethamine alone,ketorolac tromethamine combined with butorphanol tartrate shows shorter analgesia dura-tion,similar therapeutic efficacy,and lower incidence of ADR.

BACKGROUND:Fetal bovine serum based media used for expanding and cryopreserving human mesenchymal stem cells raise safety concerns in the clinical setting. OBJECTIVE:To investigate the feasibility of human umbilical cord blood plasma as a replacement for fetal bovine serum in culture and cryopreservation of human mesenchymal stem cells derived from umbilical cord. METHODS:Umbilical cord blood units were suitable for this research if they fulfil ed the donor selection criteria of the Guangzhou Cord Blood Bank strictly. Cord blood plasma was ready to use after col ected from the plasma reduction during the suitable cord blood units processing and pooling. Umbilical cord mesenchymal stem cells were harvested from the umbilical cord tissue of health ful-term newborns after delivery by enzyme digestion and were cultured in the presence of Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12 containing either fetal bovine serum or pooled cord blood plasma. Morphology, proliferation, immunophenotype detected by flow cytometry and differentiation toward adipogenic and osteogenic lineages were utilized for investigating the effect of media on umbilical cord mesenchymal stem cells after 3-5 passages. Then cells were cryopreserved in media containing 10%dimethyl sulfoxide, 20%fetal bovine serum or 20%pooled cord blood plasma for at least 6 months. Viability, adhesion, proliferation, immunophenotype and osteogenic differentiation of the cells were assessed after thawing. RESULTS AND CONCLUSION:The morphology (spindle-shaped and plastic-adherent), phenotype and differentiation potential (osteogenic and adipogenic) were almost indistinguishable between cells cultured in fetal bovine serum or cord blood plasma medium, while cells grown in cord blood plasma medium demonstrated significantly higher proliferation rates than those in medium containing fetal bovine serum. After thawing, the cells maintained their adherence to the culture surface and differentiation potential to osteoblasts, but cells from cord blood plasma cryopreservation medium showed significantly better plastic attachment and produced greater cellnumbers than fetal bovine serum for the first three post-thaw passages. The results demonstrate that cord blood plasma can sever as an effective substitute to fetal bovine serum for growth, maintenance and differentiation of umbilical cord mesenchymal stem cells, and thus it wil be a safe choice for clinical-scale production of human mesenchymal stem cells.

Objective To analyse the clinical significance of LHRH exciting test in the differential diagnosis of constitutional delayed puberty (CDP) and hypogonadotropic hypogonadism (HH). Methods Eighty-one cases from 1982 to 1998 were investigated and followed up. They were all at genital stage Ⅰ. After injection of 100 ?g LHRH, the blood samples (3 ml) were taken at -15, 0, 15, 30, 45, 60, 90 and 120 min. The serum LH and FSH levels were determined by radioimmunoassay. Then they were followed up every 3-24 months. After they received LHRH exciting test, they were followed up until over 18 years old. According to their puberty development status, they were divided into 3 groups, normal group (n=34),CDP group (n=16) and HH group (n=31),andthemeanage,whenthey received LHRH exciting test, was (10.2?0.9, range 9-14) years, (16.0?1.0, range 14-18) years and (17.1?1.4, range 16-22) years respectively. Results There were no significant differences in serum LH baseline level and peak time in normal, CDP and HH groups, but the serum LH peak level, LH increment (peak LH level minus baseline LH level), LH increment ratio (peak level/baseline level of LH) and the area under LH curve (AUC LH ) of normal group were significantly higher than those of CDP group and HH group (all P

Objective To investigate correlation between the fear related to childbirth and the social support in pregnant women in order to provide evidence for clinical intervention. Methods A total of 351 pregnant women from 2 hospitals were recruited from July to December, 2014 in city of Guangzhou. They were investigated with the self- designed questionnaire of general conditions measurement, the childbirth Attitudes Questionnaires and the perceived Social Support Scale. Results The total scores of the fear related to childbirth and the social support in pregnant women were 32.29±6.25 and 46.59±7.13, respectively. Scores of the total scale and the factors of the fear related to childbirth and the social support were negatively correlated (r=-0.798--0.134,P < 0.05). Conclusions Negative correlation exists between the fear related to childbirth and the childbirth self-efficacy in pregnant women. To reduce the fear related to childbirth, their families should be encouraged to provide more support for pregnant women.

Objective To evaluate the clinical efficacy and adverse effects of CAG regimen in treatment of primary, refractory and relapsed acute myeloid leukemia (AML) and high risk myelodysplastic syndrome (MDS), and analyse the factors influencing long-term survival. Methods Sixty-one patients with AML ( primary, n = 27; refractory, n = 18; relapsed, n = 16) and 9 patients with MDS were treated with CAG regimen. Examinations on liver and renal function, electrocardiogram and bone marrow cytology were performed before and after treatment, and adverse effects of CAG were observed. Short-term efficacy was evaluated based on clinical manifestation, peripheral blood and bone marrow cytologic examinations. Patients were followed up, overall survival ( OS) and disease free survival ( DFS) were analysed, and long-term efficacy of CAG regimen was evaluated. The factors influencing long-term survival were analysed by Log-rank test of survival curve. Results After a course of treatment by CAG regimen, the total effective rate was 71% , and 34 patients (49%) experienced complete remission. The median time of follow up was 45 months, the median OS was 28 months, and the median DFS was 23 months. Age, level of lactate dehydrogenase (LDH), remission condition after a course of treatment by CAG regimen and adoption of HD-Ara-C regimen as consolidation treatment were influencing factors for OS and DFS. The dominant clinical adverse effects were bone marrow depression, with 13 d as the median duration of agranulocytosis ( neutrophil <0.5 ×10~9/L) and 9 d as the median duration of thrombocytopenia (platelet <20 ×10~9/L). Conclusion CAG regimen may lead to favourable therapeutic effects in treatment of primary, refractory and relapsed AML and high risk MDS, and may yield less adverse effects and better long-term therapeutic effects. Age, level of LDH, remission condition after a course of treatment and adoption of HD-Ara-C regimen as consolidation treatment are dominant influencing factors for survival.

OBJECTIVE:To investigate the safety of Polyisobutylene (PIB) Gutong plaster by transdermal administration. METHODS:66 rabbits were randomly divided into a normal group,a group with intact skin and a group with damaged skin. The latter two groups were respectively re-divided into PIB group,the groups of low,medium and high-dose PIB Gutong plaster and Gutong plaster group. An acute toxicity test was conducted on the rabbits,which 14 d of continuous observation was made 24 h af-ter transdermal administration. Another 60 rabbits were divided into several groups as above except for a normal group. A single pri-mary skin irritation test was conducted on them,where skin irritation reactions were recorded 6 h after a single administration based on intra-individual left/right self comparison method. 70 guinea pigs were randomized into a negative control group (vase-line),a PIB group,a positive control group(2,4-dinitrochlorobenzene),a Gutong plaster group and the groups of low,medium and high-dose PIB Gutong plaster,which were dosed for sensitization,followed by a skin sensitization test. RESULTS:No obvi-ous toxicity symptoms could be seen after administration of PIB Gutong plaster. The rabbits’intact or damaged skin had no irrita-tion response to PIB and low and medium-dose PIB Gutong plaster. PIB Gutong plaster caused no irritation response in the rabbits’ intact skin,but slight irritation in damaged skin 1 h after administration. The allergic reaction incidence of the positive control group of guinea pigs was 100% while that of any other groups was 0. CONCLUSIONS:The PIB Gutong plaster is safe for trans-dermal administration.
