Objective To evaluate the advantages and disadvantages of transabdominal myomectomy (TAM), transvaginal myomectomy (TVM) and laparoscopic myomectomy (LM). Methods We retrospectively reviewed the clinical data of 89 cases of TAM (Group TAM), 34 cases of TVM (Group TVM) and 62 cases of LM (Group LM). Results About the operation time, the Group LM occupied the first place (123 7 min?56 7 min), the Group TAM came second (90 5 min?31 1 min), and the Group TVM last (60 7 min?20 5 min), with significant differences among the three groups ( P 0 05), but the blood loss in both of the groups was much more than that in the Group TVM ( P 0 05), but markedly lower than that in the Group TAM ( P

Objective To study the inhibitory effects of angelica A_3 active fraction (A_3) inflammation and up-regulation of cyclooxygenase-2 (Cox-2) expression of rat uterus induced by lipopolysaccharides (LPS). Methods The anti-inflammatory effects of A_3 were investigated in rats using the carrageenin-induced paw swelling model and in mice using dimethylbenzene-induced ear edema model; RT-PCR and Western blotting were used to analyze Cox-2 mRNA and the protein expression levels. Results A_3 (1, 5, and 10 mg/kg) dose-dependently inhibited dimethylbenzene-induced ear edema in mice and paw swelling in rats by ig administration. LPS 1 ?g/mL could significantly increase the level of Cox-2 mRNA and protein expression. A_3(10—320 mg/L) could concentration-dependently inhibit Cox-2 mRNA and protein over-expression stimulated by LPS. Conclusion A_3 possesses better anti-inflammatory effects than angelica oil, which maybe relates to its inhibitory effects on Cox-2 overexpression.

Aim To investigate the inhibitory effects and mechanism of action of isoliensinine (IL) on the proliferation of porcine coronary arterial smooth muscle cells (CASMCs) induced by phenylephrine (Phen) and its mechanisms of action. Methods MTT assay, immunohistochemical method and Western blotting were adopted. Results IL (0.03-3 μmol·L-1) could inhibit the CASMCs proliferation induced by Phen (0.1 μmol·L-1) in a concentration-dependent manner. IL (0.1 μmol·L-1) antagonized Phen-induced overexpression of PDGF-β and bFGF from 0.545±0.026 and 0.47±0.03 to 0.458±0.019 and 0.376±0.017 (P<0.01, P<0.01). IL (0.1 μmol·L-1) also decreased c-fos, c-myc and hsp70 overexpression induced by Phen from 0.57±0.04, 0.44±0.04 and (173±36)% to 0.46±0.05, 0.372±0.021 and (115±35)% respectively (P<0.01, P<0.01, P<0.01). Conclusion IL exerted antiproliferative effect on CASMCs induced by phenylephrine, and its mechanisms were related to decrease the overexpression of growth factors (PDGF-β, bFGF), protooncogene (c-fos, c-myc) and hsp70.

OBJECTIVE:To observe clinical efficacy and safety of Xuebijing injection combined with imipenem and cilasta-tion in the treatment of severe abdominal infection,and its effects on plasma endotoxin and inflammatory factors. METHODS:Dur-ing Apr. 2013-Apr. 2016,100 patients with severe abdominal infection in our hospital were divided into observation group and control group according to random number table,with 50 cases in each group. Both groups were given Imipenem and cilastation sodium for injection 0.5 g added into 0.9% Sodium chloride injection 500 mL,ivgtt(≥40 min),q12 h. Eight hours later,ob-servation group was additionally given Xuebijing injection 100 mL added into 0.9% Sodium chloride injection 500 mL,ivgtt, bid;Both groups were treated for 5-7 d. The levels of plasma endotoxin and inflammatory factors(TNF-α,IL-6,IL-6/IL-10) were compared in 2 groups before after treatment,and clinical efficacies and the occurrence of ADR was recorded. RESULTS:Before treatment,there was no statistical significance in plasma endotoxin or inflammatory factor levels between 2 groups(P>0.05). After treatment,plasma endotoxin and inflammatory factor levels of 2 groups were decreased significantly,and the obser-vation group was significantly lower than the control group,with statistical significance(P<0.05). The excellent and good rate of observation group was 98.00%,which was significantly higher than 78.00%,with statistical significance(P<0.05). No obvi-ous ADR was found in 2 groups. CONCLUSIONS:Xuebijing injection combined with imipenem and cilastation show significant therapeutic efficacy for severe abdominal infection,can effectively control the release of endotoxin and inflammatory factors with good safety.

AIM To study the effects of A 3 site (components), extracted from Angelica naphtha (total oil),on physiological properties of isolated rat atrium and action potential of isolated guinea pig ventricular papillary muscles. METHODS Spontaneous beats, contractile force and functional refractory period(FRP) of isolated atrial muscle were recorded according to the regular methods. Standard microelectrode intracellular recording technique was used to record action potential(AP) of ventricular papillary muscles. RESULTS A 3 site(10～160 mg?L -1 ) dramatically inhibited spontaneous beats of isolated rat right atrium and made beats stop with 160 mg?L -1 . A 3 site concentration dependently reduced contractile force of isolated rat left atrium induced by electrostimulating, with the IC 50 value of 52 3 mg?L -1 . A 3 site(40～100 mg?L -1 ) obviously prolonged FRP. The FRP was prolonged from 106 ms (as control) to 130 ms at final concentration of 100 mg?L -1 . A 3 site decreased action potential amplitude (APA), shortened 20%APD(APD 20 ) and 90%APD(APD 90 ), but had no significant effect on RP of AP. CONCLUSION The mechanism of these effects of A 3 site on myocardial physiological properties and action potential was probably associated with blocking the influx of Ca 2+ and Na +, promoting K + outflux.

Blinatumomab, as a novel bispecific antibody targeting CD19 and CD3, can induce T lymphocytes to precisely target CD19 positive B lymphocytes to apoptosis. At present, it is the only bispecific antibody approved for the treatment of hematological malignancies in China. Blinatumomab is effective in the treatment of newly diagnosed, relapsed/refractory, minimal residual disease positive patients with B-cell acute lymphoblastic leukemia (B-ALL) . It can improve the survival of the patients and is well tolerated. The further study of blinatumomab can provide theoretical basis and new ideas for induction therapy, salvage therapy and subsequent hematopoietic stem cell transplantation in patients with B-ALL.

OBJECTIVE: To assess the association of 7 single nucleotide polymorphisms (SNPs) including rs13278062 (TNFRSF10A), rs3750846 (ARMS2-HTRA1), rs429358 (APOE), rs5817082 (CEPT), rs2043085 (LIPC), rs1626340 (TGFBR1), and rs8135665 (SLC16A8) identified through genome-wide association study (GWAS) with age-related macular degeneration (AMD) among ethnic Han Chinese from Sichuan, China. METHODS: A cohort of 576 AMD patients and 572 healthy controls were enrolled in a case-control study. The SNPs were genotyped by a Mass array MALDI-TOF System. On the premise that the genotype distribution of each SNP locus in both groups satisfied Hardy-Weinberg equilibrium, the genetic pattern was analyzed and the scores of allele and genotype frequencies ware compared. RESULTS: There was a significant association between TNFRSF10A rs13278062 and AMD under the heterozygous model (P = 0.000, OR = 1.529, 95%CI = 1.196-1.954) and the dominant model (P = 0.002, OR = 1.459, 95%CI = 1.154-1.865), suggesting that subjects carrying rs13278062GT and rs13278062TT + GT are more likely to develop the AMD, whereas no significant difference was observed for rs13278062 under other models. No association was detected with the other six SNPs and AMD under various genetic models. CONCLUSION This case-control association study has indicated that TNFRSF10A rs13278062 is associated with AMD under the heterozygous and dominant models, suggesting that the TNFRSF10A variant may be involved in the development of AMD among ethnic Han Chinese population.
