The clinical manifestations, laboratory tests and treatment of 5 cases of simple virilizing with 211-hydroxylase deficiency were analyzed. The average age was 17 at the first hospital visit. The manifestation included abnormal external genitalia at birth, no secondary sexual characteristics developed during adolescence and no menstrual cycles, and their near-adult height (NAH) was affected. The chromosome karyotype of the patients was 46 XX. The CT scans showed bilateral adrenal hyperplasia. The testosterone levels were (665 ± 334 ) μg/L, which were reduced to (81 ± 25 ) μg/L after dexamethasone suppression. The levels of adrenocorticotropic hormone were 123 (57 - 563) ng/L and ＜ 5 ng/L respectively before and after dexamethasone suppression test. Early diagnosis and early treatment is particularly important for improvement of the disease outcomes.

In MAST (mRNA accessible site tagging),the DNA tags from synthesized library were employed for identifying mRNA accessible sites. A large number of tags were amplified and subcloned for sequencing to verify mRNA binding profiles. A PCR was designed by using one primer which bridges over the tag terminal sequences. In PCR reaction DNA tag fragments were concatemerized by a bridge primer in reaction cycles. The concatemerized tag fragments were subcloned and sequenced. Dozens of the concatemerized sequences contained thousands tags. The PCR was a simple,effective way which for sequencing tags in a high through put manner.

Objective To study the inhibitory effect on the expression of regulated upon activation,normal T cell expressed and secreted (RANTES) and monocyte ehemotactic activity of ectopic endometrial stromal cells by nuclear factor(NF)-kB decoy oligonucleotides (ODN). Methods The stromal cells of ectopic endometrium were divided into 3 groups. Two groups were cultured with or without 10 μg/L of interleukin (IL)-1β. Another group was transfected with NF-kB decoy ODN with the aid of a lipofectamine reagent. After 4 h of transfection, 10 μg/L of IL-1β was added to induce the stromal cells to secrete RANTES. Concentration of RANTES in the supernatant at 4, 8, 12, 24 and 36 h was measured with the sandwich enzyme linked immunosorbent assay (ELISA). U937 monocyte chemotactic activity was assayed in Boyden chambers. The specific RANTES-neutralizing monoclonal antibodies at serial doses (0. 5, 1, 2, 4and 8 mg/L) were added into IL-1β induced medium of 24 h to detect the monocyte chemotactic activity of RANTES in supernatant. Results The concentration of RANTES secreted by stromal cells was respectively (58 ± 10), ( 150 ± 35 ), ( 360 ± 46 ) and ( 586 ± 42 ) ng/L after IL-1β stimulation for 8,12,24 and 36 h,significantly higher than that of stromal cells cultured without IL-1β. The concentrations of RANTES were respectively (86±16), ( 128±28 ) and ( 183±32) ng/L after IL-1β stimulation for 12, 24 and 36 h in stromal cells transfected with NF-kB decoy ODN, evidently lower than that of stromal cells stimulated with IL-1β alone. The monocyte ehemotactic index of 12, 24, 36 h in conditioned medium of stromal cells transfected with NF-kB decoy ODN was respectively 10. 3 ± 0. 9, 13.7 ± 1.1, 18.6 ± 1.2, which was evidently lower than that of stromal cells stimulated with IL-1β alone. The anti-RANTES antibody at 0. 5, 1,2, 4 and 8 mg/L inhibited respectively 5%, 23%, 40%, 62% and 61% of the chemotactic activity in 12 h medium treated with IL-1β. Conclusions RANTES accounts for the majority of the monocyte chemotactic activity in IL-1β induced medium of 24 h. NF-kB decoy ODN may influence the feed-forward inflammatory loop whereby IL-1β from activated macrophages can lead to RANTES production by ectopic implants and further monocyte chemotaxis.

OBJECTIVETo explore the influences of anti-CD47 monoclonal antibody (mAb) B6H12 on the differentiation and function of cultured dendritic cells (DCs).

METHODSHuman peripheral monocyte derived DCs were propagated with granulocyte-macrophage colony-stimulating factor (GM-CSF) and lipopolysaccharide (LPS) plus interleukin-4 (IL-4) in the presence or absence of soluble B6H12. Flow cytometry was used to analyze the immunophenotypes of cells, semi-quantitative RT-PCR and ELISA methods to analyse the mRNA and protein expression levels of interleukin-12 (IL-12). The antigen-presenting function of DCs was determined in one-way mixed leukocyte reaction by Brdu-ELISA technique.

RESULTSThere was a high expression rate (94% approximately 98%) of CD47 molecules in DCs. The cell immunophenotypes in B6H12 mAb treated and untreated DC groups were as follows: CD80(+) (68.14 +/- 7.41)% vs (89.17 +/- 8.59)%; CD86(+) (67.33 +/- 4.71)% vs (87.27 +/- 3.56)%; CD83 (40.08 +/- 14.80)% vs (72.77 +/- 8.68)%; CD1a(+) (66.45 +/- 4.06)% vs (95.93 +/- 3.03)%; and HLA-DR (40.67 +/- 13.48) vs (98.97 +/- 1.01)%, respectively. The expression levels of mRNA and protein of IL-12 were strongly inhibited in B6H12 mAb treated DC (P < 0.01). The quantity of Brdu was also lower in B6H12 mAb treated DC than that in untreated DCs (P < 0.01).

CONCLUSIONThe anti-CD47 McAb exerts a negative effect on the maturation and functions of cultured DCs.

Targeting rRNA of bacteria is a new strategy for antibiotic agent development. The rRNA such as mRNA are naturally self-folded molecules which expose only limited accessible target-sites for binding. These accessible sites are pivotal for designing the effective antisense oligonucleotides, ribozymes, and DNAzymes. MAST, an RNA accessible site screening method, illustrated 6 accessible sites on 16S rRNA by immobilizing 16S rRNA and hybridizing with oligonucleotide library. 5 of the accessible sites were identified valid, and the antisense oligonucleotides targeted to which showed inhibition effectiveness on the proliferation. Among the 5 target sites, one showed the priority of accessibility. Ribozyme designed to this site showed obvious inhibition to the growth when induced expressing in the transfection E.coli.

Objective To assess the intervention effect of upper limb rehabilitation exercise video on life quality in patients after modified radical mastectomy. Methods A total of 160 breast cancer patients received modified radical mastectomy were from Shanghai Jiading District Maternal and Child Health Hospital from June 2017 to June 2019.They were randomly divided into control group and observation group with 80 cases in each group.The patients in the control group were trained with routine upper limb rehabilitation exercise, and the patients in the observation group were given video training for upper limb rehabilitation exercise.Quality of life (QOL), anxiety scale and depression scale were used for corresponding evaluations.Satisfaction and compliance scales were also used for evaluation. Results Before intervention, there was no significant difference in each index between the two groups (P>0.05).After intervention, the quality of life in the observation group was better than that in the control group, including life status (21.43±4.83), functional status (19.69±4.72), emotional status (19.83±4.36), social/family status (19.59±3.62) and additional attention (24.73±3.27).There was no statistically significant difference in these parameters before and after intervention in the control group (P>0.05).The scores of anxiety (36.37±5.64) and depression (37.28±4.47) in the observation group were lower than those in the control group, and the differences were statistically significant.The nursing satisfaction of patients in the observation group was much higher than that in the control group (91.25% vs 77.50%), and the proportion of compliance was higher than that in the control group (97.50% vs 68.75%). Conclusion In breast cancer patients received radical mastectomy, video-guided rehabilitation training can improve the quality of life and nursing satisfaction, compliance of rehabilitation, and condition of anxiety and depression.

Public hospitals reform is a key roadblock for the ongoing health reform.By means of such experiments as Three openings and three mechanisms,Beijing is practicing a separation of hospital regulation and management and separation of clinic and pharmacy,while building the mechanism of financial subscription for pricing,that of medical insurance adjustment,and that of hospital corporate governance.These measures aim at building a new management structure,operation mechanism and medical service model focusing on quality of care,efficiency and satisfaction.Separation of clinic and pharmacy has lowered drug proportion,average outpatient expense and out of-pocket payment of patients,as well as producing higher patient satisfaction,quality of care and hospital income.Other benefits include better management efficiency indirectly caused by separation of clinic and pharmacy,higher acceptance of the corporate governance,and service model innovation to better serve the people.
