Objective:To research the clinical effect of abdominal total hysterectomy on the patients with uterine fibroids and the serum vascular endothelial growth factor (VEGF) and interleukin 6 (IL-6),interleukin 8 (IL-8) levels.Methods:106 cases of patients with uterine fibroids from February 2014 to February 2016 were divided into the control group and the research group according to the lottery method,the control group was treated with total abdominal hysterectomy,while the research group was given abdominal total hysterectomy treatment,the operation time,blood loss,anal exhaust time,length of hospital stay,changes of serum VEGF,IL-6,IL-8,Follicle stimulating hormone (FSH),estradiol (E2) levels,resistance to seedling le tube hormone (AMH) before and after the surgery as well as the occurrence of complications were compared between two groups.Results:The operation time,blood loss,length of hospital stay,anal exhaust time of research group were significantly shorter than those of the control group (P＜0.05).Before surgery,the serum levels of VEGF,IL-6,IL-8,FSH,E2,AMH showed no difference between two groups (P＞0.05).After the operation,the serum levels of IL-6,IL-8,E2,AMH of research group were lower than those of the control group (P＜0.05),the serum level of FSH in research group was higher than that of the control group (P＜0.05).The serum level of VEGF showed no difference between the two groups (P＞0.05).The incidence rate of complications in research group was lower than that of the control group (P＜0.05).Conclusion:Abdominal total hysterectomy showed similar effect with the abdominal hysterectomy in the treatment of uterine fibroids patients,but the abdominal full hysterectomy induced less trauma,promoted the recovery of ovarian function after surgery,which might be related to the decrease of serum IL-6,IL-8 and VEGF levels.

Objective To investigate changes and the significance of Th17/Treg immune imbalance in secondary systemic infection in patients with severeacute pancreatitis.Methods We selected 21 patients with severe acute pancreatitis and secondary systemic infection (infection group),25 patients with severe alone (non-infection group),20 healthy cases undergoing annual health checkup (control group) in this study.The expression levels of Th17/Treg cells and related cytokines were compared between groups.Results There were significant differences in mortality rate and duration of ICU stay between infection group and non-infection group [23.8％ vs.4.0％,(11.3±3.4) d vs.(7.5±2.8) d,x2=3.949,t=2.890,P=0.047 and0.045].The percentages of Th17 cell andTreg cell,Th17/Treg ratio,mRNA expressions of IL-6,IL-17,IL-23,TGF-β and orphan receptor γt were higher in infection and non infection groups than in control group [(26.4 ± 1.2) ％,(12.8 ± 0.9)％ vs.(3.1±0.8) ％;(6.7±1.6)％,(4.2±1.3)％ vs.(1.3±0.4)％;(4.3±1.0)％,(3.2±1.1)％ vs.(2.4±0.9)％;(7.1±0.8)ng/L,(5.3±0.7)ng/L vs.(0.2±0.1)ng/L;(22.9±2.4)ng/L,(15.6±2.8)ng/L vs.(10.3± 1.5)ng/L;(15.7±2.1)ng/L,(10.2± 1.5)ng/L vs.(8.3± 1.4)ng/L;(23.6±2.2)ng/L,(16.3±1.7)ng/L vs.(11.6±1.1)ng/L;(0.052±0.014),(0.035± 0.010) vs.(0.004±0.001);F=15.761,55.745,9.437,102.788,21.038,16.239,36.957,23.924,respectively,P=0.555,0.000,0.014,0.000,0.002,0.004,0.000,0.000].The mRNA expressions of IL-10 and Foxp3-T were lower in infection and non-infection groups than in control group [(6.4±1.1)ng/L,(10.5 ± 2.1) ng/L vs.(15.4±2.0)ng/L;(0.005±0.001),(0.020±0.007) vs.(0.032±0.009),F=18.995 and 20.608,P=0.003 and 0.002].Conclusions The secondary infection can aggravate the Th17 / Treg immune imbalance in patients with severe acute pancreatitis,and extend the ICU hospitalization days.

Objective To investigate whether clinical,endocrine,and sonographic characteristics of infertile women with polycystic ovary syndrome (PCOS) could predict the ovarian response to clomiphene citrate (CC) medication.Methods A prospective study was conducted,85 women with PCOS were given CC 50 mg per day for 5 days.In the case of an absent response,doses were increased to 100 daily in subsequent cycles.Clinical,endocrine,and sonographic characteristics were compared between responders and nonresponders.Results The cycle history (oligomenorrhea or amenorrhea) and antral follicle count (AFC) were significantly different in responders from those in nonresponders (P ＜ 0.05).There were no differences in age,serum testosterone,follicle stimulating hormone (FSH),luteotropic hormone (LH),body mass index (BMI),insulin resistant index (HOMA-IR),and glucose and insulin levels between the two groups (P ＞ 0.05).In addition,multivariate logistic regression analysis indicated that cycle history and AFC were the predictors of ovarian response to CC treatment.Conclusions The cycle history and AFC can be used as the simple and effective parameters to predict ovarian response to CC treatment in PCOS patients.

Combination chemotherapy and nanoparticle drug delivery are two promising strategies in cancer treatment. The use of multiple therapeutic agents in combination provides synergistic effects among different drugs against cancer cells and suppresses drug resistance through distinct mechanisms of action.Nanocarriers can improve anti-tumor effects of drugs and reduce systemic toxicity through delivering drugs into the tumor tissue specially. Recently, many studies are aiming to encapsulate multiple agents into nanocarriers to optimize the anti-tumor effects. In the present review, the recent advances of nanoparticle platforms applied with co-delivering two or more drugs were summarized and the various combination strategies based on nanoparticles in oncology were discussed.
