Objective To investigate the feasibility,safety and clinical efficacy of transvaginal myomectomy.Methods A total of 92 patients with uterine leiomyoma were given either vaginal myomectomy(Study Group,n=46) or abdominal myomectomy(Control Group,n=46).Clinical outcomes between the two groups were compared.Results Both vaginal and abdominal myomectomy were performed successfully.The operation time between the two groups was not statistically significant(t=-0.734,P=0.465).There were significant differences between the Study Group and the Control Group in the intraoperative blood loss(60.4(?5.6 ml) vs 82.5?50.2 ml;t=-2.210,P=0.000),the time to first passing flatus(15.3?3.2 h vs 27.5?4.8 h;(t=-14.343,)P=0.030),the incidence of postoperative pain (?~2=29.447,P=0.000),the rate of postoperative pyrexia(?~2=3.903,P=0.048),and the hospital stay(3.1?0.4 d vs 5.2?1.1 d;t=-12.169,P=0.000).Conclusions Transvaginal myomectomy has advantages of little invasion,quick recovery of bowel movement,slight postoperative pain,low rate of postoperative pyrexia,and short hospital stay,being a safe and feasible minimally invasive option for uterine leiomyoma.

Objective To investigate the relationship between fractional exhaled nitric oxide (FENO) and asthma predictive index (API) in infants under 3 years of age. Methods Totally 62 cases (under 3 years of age) who were hospitalized from June 2015 to June 2016 and had more than 3 times wheezing over the past year were enrolled in this study. They were divided into two groups according to API:API positive group with 37 cases and API negative group with 25 cases. FENO levels and peripheral blood eosinophil levels were detected and skin prick allergy test (inhalation and ingestion of allergens)was done in all selected children, did skin prick allergy test (inhalation and ingestion of allergens), simultaneous detected peripheral blood eosinophil levels. The parents of the children were investigated by questionnaire to know the children′ history about atopic dermatitis (such as urticaria, eczema, etc) and parents′ wheezing history. Above information was recorded and statistics analysis was made. Results There were no significant differences between two groups in atopic dermatitis inhalation and ingestion of allergens (P<0.01 or <0.05). The level of FENO in API positive group and API negative group was (16.70 ± 11.07), (13.52 ± 11.01) ppb(1 ppb=1 × 10- 9 mol/L), and there was significant difference (P<0.01). Conclusions There are associations between FENO and API, and they have good reference value in predicting the risk of asthma.

0.05). The ROM of flexion-extension, lateral bending and axial rotation of these two groups was smaller than that of the other three fixators(P0.05). Conclusion Experimentally, the effect of TARP was equal to that of Magerl+Brooks, but it was proved to be more stable than the other three clinically widely used atlantoaxial fixators: Magerl, Brooks and anterior transarticular screw fixation through C 2 vertebral body. TARP's C 1 and C 2 screws were strong enough for atlanto-axial arthrodesis. TARP's biomechanical performance was excellent.

Objective To study whether solasodine hydrochloride (SBHL) could enhance the effect of arsenic trioxide in inducing apoptosis and affecting telomerase activity in cervical cancer HeLa cells. Methods Using cell culture methods, cervical cancer HeLa cells were cultured in vitro. The optimal concentration of SBHL was determined by MTT method from 0, 10, 20, 40, 80, 160, to 320 μmol/L. HeLa cells were grown in improved RPMI1640 supplemented respectively with arsenic trioxide(5 μmol/L As2O3), As2O3(5 μmol/L)+ SBHL( 40 μmol/L) and none (control group). The growth morphology of HeLa cells was observed under phase contrast microscopy after culture for 24, 48, and 72 h. Apoptosis of HeLa cells was determined under transmission electronic microscopy. The method of MTT was used to study the cell survival percentage. The technique of flow cytometry was used to measure cell cycle and cell apoptosis percentage. The method of tartrate-resistant acid phosphatase-enzyme linked immunosorbent assay (TRAP-ELISA) was used to determine telomerase activity of HeLa cells. Results Under phase contrast microscopy, in control group HeLa cells were round, densely packed; in As2O3 group the numbers of the cells were less, cell spacing increased; in As2O3 + SBHL group the cells shrinked significantly, nuclear fragmented as a petal-like, gap became larger. Under transmission electronic microscopy, there were rich microvillus on the cell surface in control group, cell intervals clear, immature connections, and the intervals did not close. The structure of the mitochondria in the cytoplasm was integrated. Most of the chromatin in the nucleus were, euchromatin and characteristics of apoptosis with heterochromatin increased and the chromatin condensed into masses, on the boundary of nuclear membrane. The microvillud on the cell surface were ruptured and decreased in As2O3 + SBHL group. The chromatin condensed into masses. The formation of apoptotic bodies was observed. The difference was statistically significant between groups in cell survival percentage at 24, 48, 72h(x2 = 10.39 , 13.88 , 17.21,respectively, all P < 0.05). Cell survival percentage in SBHL + As2O3 group (52.80%) was significantly less than that of As2O3 group(77.51%, x2 = 9.29, P < 0.05) at 72 h. In cell cycles, the difference was statistically significant between groups in C1 phase and S phase(F = 7.46,22.14, all P < 0.05), respectively. Compared with , control group[ (41.57 ± 1.56)%, (50.45 ± 2.37)%], cell percentages in S phase in As2O3 + SBHL group[(20.06 ± 4.98)%] and As2O3 group[(27.10 ± 5.32)%] were decreased(P< 0.05 or < 0.01), while cell percentage in C1 phase was increased[(58.70 ± 5.18)%, (69.67 ± 4.17)%, P< 0.05 or < 0.01]. The difference was statistically significant between groups in apoptotic percentage of HeLa cells (F = 4.01, P < 0.05). Compared with control group[ (1.18 ± 1.40)%], apoptosis percentage was significantly increased in As2O3 + SBHL group and As2O3 group [(21.08± 1.22)%, (6.04±2.53)%, P< 0.05 or < 0.01], respectively, and As2O3 + SBHL group was higher than As2O3 group(P < 0.01). The difference was statistically significant between groups in telomerase activity (F = 21.28, P< 0.05). Telomerase activity was inhibited in As2O3 group(1.214 ± 0.621) and As2O3A + SBHL group(0.865 ± 0.284) compared to control group (2.107 ± 0.057, all P < 0.05), and telomerase activity in As2O3 + SBHL group was lower than that of As2O3 group (P < 0.05). Conclusions SBHL enhances the effect of As2O3 in inducing apoptosis in HeLa cells, which is related to its inhibiting telomerase activity in HeLa cells.

OBJECTIVEE23K polymorphism in KCNJ11 gene is associated with cardiovascular disease and diabetes. In order to explore the mechanism of E23K correlation to related diseases, the effect of E23K polymorphism in KCNJ11 gene on membrane current was investigated.

METHODSThe exon of KCNJ11 was obtained by PCR amplification and the G-->A mutation was completed by overlap extension PCR. The sequences of KCNJ11 exon contained 23E or 23K was inserted into pcDNA3.1/CT-GFP vector respectively. The recombinant plasmid, pcDNA3.1-KCNJ11(E) and pcDNA3.1-KCNJ11(K), were transfected into HEK293T cells by lipofectamine and the membrane current density was determined by whole-cell patch clamp technique.

RESULTS1,173 bp sequences of KCNJ11 gene's exon were amplified by PCR and the recombinant expression plasmid, pcDNA3.1-KCNJ11(E) and pcDNA3.1-KCNJ11(K), were constructed successful. Positive and negative currents were detected in HEK293T cells transfected with difference plasmid by whole-cell patch clamp technique. Results showed that the reversed voltage was 50mV. The current in HEK293T cells with pcDNA3.1-KCNJ11(E) was significantly greater than that with pcDNA3.1-KCNJ11(K) (P < 0.05, n = 10).

CONCLUSIONThe polymorphism of E23K in exon of KCNJ11 gene changed the membrane currents in HEK293T cells. It could be an experiment support for the possible mechanism between the locus and related diseases.
