Objective To investigate the relationship between the expression of estrogen receptor (ER),progesterone receptor(PR)and epidermal growth factor receptor(EGFR)in uterine leiomyoma and the recurrence after myomectomy.Methods Eighty cases underwent myomectomy were enrolled in this study.ER,PR and EGFR expression in uterine leiomyoma tissue and normal myometrium tissue were examined by immunohistochemical technique.All the patients were followed up regularly after myomectomy.Results The positive expression rate of ER,PR and EGFR in uterine leiomyoma tissue were significantly higher than those in normal myometrium tissue[88.8％(71/80)vs.48.8％(39/80),92.5％(74/80)vs.30.0％ (24/80),86.2％(69/80)vs.57.5％(46/80),P ＜ 0.05].The recurrence rates in ER,PR and EGFR positive expression patients were significantly higher than those in negative expression patients[42.3％(30/71)vs.22.2％(2/9),41.9％(31/74)vs.16.7％(1/6),42.0％(29/69)vs.27.3％(3/11),P ＜ 0.05].The recurrence times in ER,PR and EGFR positive expression patients were significantly shorter than those in negative expression patients(P ＜0.05).The expression of EGFR had positive correlation with ER and PR(r =0.837,0.702,P ＜ 0.05).Conclusions The recurrence of uterine leiomyoma may have correlation with high expression of ER,PR and EGFR in uterine leiomyoma.

To investigate roles of nitric oxide (NO) signal in accumulations of phenolic acids in abscisic.acid (ABA)-induced Salvia miltiorrhiza hairy roots, S. miltiorrhiza hairy roots were treated with different concentrations of sodium nitroprusside (SNP)-an exogenous NO donor, for 6 days, and contents of phenolic acids in the hairy roots are determined. Then with treatment of ABA and NO scavenger (2-(4-carboxy-2-phenyl)-4,4,5,5-tetramethylimidazoline-1- oxyl-3-oxide, c-PTIO) or NO synthase inhibitor (NG-nitro-L-arginine methyl ester, L-NAME), contents of phenolic acids and expression levels of three key genes involved in phenolic acids biosynthesis were detected. Phenolic acids production in S. miltiorrhiza hairy roots was most significantly improved by 100 µmoL/L SNP. Contents of RA and salvianolic acid B increased by 3 and 4 folds. ABA significantly improved transcript levels of PAL (phenylalanine ammonia lyase), TAT (tyrosine aminotransferase) and RAS (rosmarinic acid synthase), and increased phenolic acids accumulations. However, with treatments of ABA+c-PTIO or ABA+L-NAME, accumulations of phenolic acids and expression levels of the three key genes were significantly inhibited. Both NO and ABA can increase accumulations of phenolic acids in S. miltiorrhiza hairy roots. NO signal probably mediates the ABA-induced phenolic acids production.

AIM: To investigate in vitro effects of cholecystokinin octapeptide(CCK-8) on the expressions of B7.1 and B7.2 and the costimulatory activity of T lymphocytes in unstimulated macrophages.METHODS: Mouse peritoneal macrophages were isolated and incubated with CCK-8(10-12-10-6 mol/L) for indicated time.The B7.1 and B7.2 expressions of murine peritoneal macrophages were analyzed by flow cytometry.CD4+T cells were isolated from mouse spleen using immunomagnetic beads,and cultured with 1/4 numbers of macrophages which were pretreated with CCK-8 and/or anti-B7.1 antibody,anti-B7.2 antibody,CCK1R antagonist CR1409,CCK2R antagonist CR2945 for 24 h.ConA was added into the culture medium to stimulate CD4+T cell proliferation.The proliferation was determined by measuring -TdR incorporation in a ?-scintillation counter.RESULTS: B7.1 and B7.2 expressions and costimulatory activity of peritoneal macrophages were enhanced by CCK-8 in a dose-dependent manner,and the maximal effects occurred at the concentrations of 10-9 mol/L to 10-7 mol/L.Anti-B7.2 antibody,but not anti-B7.1 antibody,reduced the modulatory role of CCK-8 on costimulatory activity.Both CR1409 and CR2945 reversed the effect of CCK-8 on costimulation,and the role of CR1409 was more significant.CONCLUSION: CCK-8 enhances macrophage costimulatory activity by upregulating B7.2 expression,which is mediated by CCK1R and CCK2R.CCK1R might be the major receptor responsible for the modulation of CCK-8 on costimulation.

Objective To investigate the relationship of relative telomere length in cumulus cells(CCs) with oocytes at different mature stages and the outcome of intracytoplasmic sperm injection and embryo transfer (ICSI-ET). Methods Oocyte-cumulus complex samples were collected from 92 patients undergoing ICSI-ET and patients were divided into group A including 55 women≤35 years and group B 37 women>35 years. The embryonic development ability and the result of clinical pregnancy were recorded in different groups. DNA was extracted from CCs and assessed for telomere length by real-time quantitative PCR. Results In ICSI-ET,the relative telomere length of CCs gradually shortened with the age.There was a significantly longer telomere length of CCs in the preg-nant subgroup than that in the non-pregnant subgroup in the two groups(P < 0.05). Conclusion The telomere length of CCs may be associated with the pregnancy outcome in ICSI-ET.

Objective This study is to compare flap-viability-related complications, coverage reach, recon-struction outcomes and donor-mobidities between distally-based peroneal artery perforator-plus fasciocutaneous (DPAPF)flap and distally-based posterior tibial artery perforator-plus fasciocutaneous(DPTAPF)flap for recon-struction of soft-tissue defects over the distal lower leg, ankle and foot, and thus provide evidence for selection of the flaps. Methods Between April, 2002 and February, 2012, 216 and 59 patients underwent the reconstructions with DPAPF flaps(peroneal group)and DPTAPF flaps(posterior tibial group)respectively. We subdivided the distal lower leg, ankle and foot into 12 subregions. In all the patients, flap-viability-related complications and its potential risk factors(including age,sex,etiology,location of top edge,location of pivot point,length and width of both the skin is-land and adipofascial pedicle, length-width ratio, and total length), coverage reach(the subregion in which the most distal part of the reconstructed defect lies),duration of flap elevation and hospital stay were compared between the two groups. In patients with at least 3 months postoperative follow-up, comparative study of reconstruction outcomes, pa-tient's satisfaction with flap appearance and donor-site morbidities were performed between the groups. Results Partial necrosis rate in the peroneal of the posterior tibial group were 12.0 percent versus 20.3 percent,respectively(P> 0.05). Marginal necrosis and overall complication (including partial and marginal necrosis)rates in the peroneal group(1.9 percent and 13.9 percent, respectively)were significantly lower than those in the posterior tibial group (8.5 percent and 28.8 percent,respectively)(P<0.05).Incidence of partial necrosis of the flaps for the defects over subregions 7 to 10 in the peroneal group(7 of 41)was significantly lower than that in the posterior tibial group(2 of 2).There was no difference in reconstruction outcomes and patient's satisfaction with flap appearance in both groups(P >0.05).Incidences of hypertrophic scar,itching and pigmentation at the donor site were significantly lower in the peroneal group(P<0.05). Conclusion DPAPF flap is superior to DPTAPF flap in reliability,safe coverage reach and less donor-site morbidities.The former is recommended as the first choice when local pedicle flaps are considered to recon-struct soft-tissue defects over the distal lower leg,ankle and foot.

Objective: To explore and analyze the effects of airway management team (AMT) in the treatment of severely mass burn patients combined with inhalation injury. Methods: The clinical data of 58 severely burned patients combined with inhalation injury hospitalized in our unit from January 2012 to August 2014, conforming to the inclusion criteria, were retrospectively analyzed. According to whether airway management was implemented by AMT or not, patients hospitalized from January 2012 to July 2014 were divided into control group (n=27), while patients in Kunshan factory aluminum dust explosion accident hospitalized on 2nd August 2014 were divided into observation group (n=31). Patients in control group received regular airway nursing carried out by nurses on duty, while patients in observation group received specialized airway concentration nursing implemented by AMT. The concrete implementation included overall assessment of patients′ airway, elaborate airway care, and controlled management of mechanical ventilation. Arterial blood gas indexes and oxygenation index of patients in the two groups on post injury day (PID) 1, 7, and 14 were compared. Sputum viscosity, ventilator-associated pneumonia (VAP) occurrence rate, and ventilation time of patients in the two groups in post injury week(s) 1, 2, and 3 after admission were monitored and recorded. Survival rates of patients in the two groups were compared. Data were processed with analysis of variance for repeated measurement, t test and Bonferroni correction, chi-square test, and Wilcoxon rank sum test. Results: (1) There were no statistically significant differences in pH value, arterial partial pressure of oxygen (PaO₂), arterial partial pressure of carbon dioxide (PaCO₂), arterial oxygen saturation (SaO₂), and oxygenation index of patients in the two groups on PID 1 (t=0.595, -0.166, 1.518, -0.828, 0.458, P>0.05). The pH values of patients in observation group on PID 7 and 14 were 7.327±0.050 and 7.367±0.043, respectively, significantly better than those in control group (7.304±0.021 and 7.390±0.029, respectively, t=-2.385, 2.391, P<0.05). The PaO₂ values of patients in observation group on PID 7 and 14 were (95.1±6.7) and (106.3±7.8) mmHg (1 mmHg=0.133 kPa), respectively, significantly higher than those in control group [(91.6±5.7) and (102.0±8.3) mmHg, respectively, t=-2.109, -2.059, P<0.05]. The PaCO₂ values of patients in observation group on PID 7 and 14 were (41±4) and (40±4) mmHg, respectively, significantly lower than those in control group [(43±5) and (43±4) mmHg, respectively, t=2.220, 2.304, P<0.05]. The SaO₂ values of patients in observation group on PID 7 and 14 were 0.95±0.04 and 0.96±0.04, respectively, significantly higher than those in control group (0.93±0.05 and 0.94±0.05, respectively, t=-2.201, -2.016, P<0.05). The oxygenation indexes of patients in observation group on PID 7 and 14 were (286±18) and (329±20) mmHg, significantly higher than those in control group [(277±14) and (306±58) mmHg, respectively, t=-2.263, -2.022, P<0.05]. (2) Sputum viscosity of patients in observation group in post injury week(s) 1, 2, and 3 were superior to that in control group (Z=-2.096, -2.076, -2.033, P<0.05). (3) VAP occurrence rate of patients in observation group was lower than that in control group, and time of mechanical ventilation of patients in observation group was shorter than that in control group (χ²=4.244, t=2.425, P<0.05). (4) Survival rate of patients in observation group was higher than that in control group (χ²=4.244, P<0.05). Conclusions The special intensive care of airway management by AMT can effectively improve the oxygenation status of severely burned patients combined with inhalation injury, alleviate the sputum viscosity, reduce the occurrence of VAP, and shorten the time of mechanical ventilation, thus benefits the treatment of severely mass burn patients combined with inhalation injury.

Objective To observe any effect of pulmonary rehabilitation in preventing ventilator-associated pneumonia (VAP) among patients receiving invasive mechanical ventilation (MV). Methods A total of 117 a-dults who had be receiving mechanical ventilation for at least 48 hours were randomly divided into an observation group and a control group. Both groups were given routine drug treatment and nursing, but the observation group al-so received comprehensive and individualized pulmonary rehabilitation interventions including airway clearance, respiration training, electrical stimulation of the sacral nerve, lung expansion and early mobilization. The main indi-cators were the incidence of VAP, mortality, MV duration, ICU stay time, and total hospital stay. Results At the end of the treatment the average clinical pulmonary infection score, the acute physiology and chronic health e-valuation Ⅱ score, SpO2 level and oxygenation index of the observation group were all significantly better than those of the control group. The incidence of VAP within one month after leaving the ICU was 47. 5％ in the observation group and the mortality rate was 44.1％, both significantly lower than in the control group. The average MV dura-tion, total hospitalization time and the ICU stay of the observation group were also significantly shorter than those of the control group. Conclusion Early and comprehensive pulmonary rehabilitation can prevent VAP and shorten the length of hospital stays, ICU stays and time on a mechanical ventilator, improving patients' survival chances and prognoses.
