Objective To explore the animal model of syndrome used in the study of hot flash phenomenon in women.Methods Twenty-four female SD rats were divided randomly into three groups:Con group,Ovx group,and tamoxifen group(n = 8 rats per group).Hot flashes were induced by bilateral oophorectomy and intragastric tamoxifen 10 mg/(kg·d),respectively.Open-field activity,anal temperature,and body surface infrared thermograms were detected on model days 14 and 28.The rats were then killed on day 29 and their uteruses were removed,weighed,and sectioned.Blood estradiol and catecholamine levels were determined by enzyme-linked immunosorbent assay.Gene expression levels of adrenal sex hormone synthetases(Star,Cyp11a1,Cyp17a1,Cyp19a1,Por,Hsd3b2,Hsd17b1)and catecholamine synthetases(Th,Ddc,Dbh,Pnmt)in the adrenal medulla were detected by reverse transcription-polymerase chain reaction.Results Rat body weight was significantly higher in the Ovx group compared with Con group(P<0.01),while body weight increased slowly in the tamoxifen group.The maximum body surface temperature was significantly decreased on day 28 in the Ovx group(P<0.01),the difference between the maximum and minimum abdominal temperatures was significantly increased on day 14(P<0.05),the difference between the maximum and minimum temperatures on the back was significantly increased on day 28(P<0.01),and the open-field activity was decreased(P<0.01).Compared with the sham operation group,the maximum body surface temperature in the tamoxifen group was significantly decreased(P<0.01)but the open-field activity was increased(P<0.01).The uterine index was significantly decreased in both models(P<0.01).Estradiol levels were significantly decreased(P<0.01)and NE and epinephrine were also significantly decreased in the Ovx group compared with Con group(P<0.05),and β-EP was also significantly decreased in Ovx group(P<0.05).Adrenal Cyp11a1 gene expression was significantly increased(P<0.05)while Cyp17a1 and Hsd17b1 gene expression levels were significantly decreased(P<0.05)in bilateral ovariectomized rats compared with Con group.Compared with Con group,gene expression levels of Star and Por were significantly increased(P<0.01)while Cyp17a1 gene expression was significantly decreased(P<0.01)in the tamoxifen group,and Pnmt gene expression was significantly down-regulated in Ovx group(P<0.01).Conclusions Bilateral ovariectomized rats can be used for the study of perimenopausal hot flashes,which resemble kidney Yang and Yin deficiency in traditional Chinese medicine.

Objectives:To assess bowel function and quality of life in patients with ulcerative colitis (UC)after ileal pouch anal anastomosis (IPAA).Methods:Clinical data of 37 UC patients after IPAA between 2014 and 2017 were retrospectively analyzed at Sir Run Run Shaw Hospital School of Medicine Zhejiang University. The IBDQ and Bowel Function questionnaire were used for analyzing correlation between clinical variables and quality of life or bowel function.Results:Laparoscopic operation was performed in 12 cases at stage 2 and 25 cases at stage 3. Postoperative defecation of stage 3 patients were better than that of stage 2 ( t=6.72, P<0.05). The number of daily defecation in age >45-year-old group was more than that in <45-year-old ( t=3.49, P<0.05), and the rate of evening stool seepage in the older group was higher than in the younger group( t=5.28, P<0.05). The total score of intestinal symptoms of IBDQ in patients of pouchitis was lower than that without pouchitis ( r=0.330, P<0.05). The total score in age >45 in terms of systemic symptoms ( r=0.349, P<0.05) and emotional function ( r=0.379, P<0.05) was higher than age <45. Conclusions:Outcomes of UC patients after IPAA are satisfactory, bowel function and quality of life is related with age, and stage of IPAA affect postoperative defecation.

Objective To evaluate the effects of turmeric volatile oil (TVO) combined with cisplatin on the proliferation and apoptosis of a human cutaneous squamous cell carcinoma cell line A431,and to explore their mechanisms.Methods Some cultured A431 cells at exponential growth phase were divided into several groups to be treated with 5,10,20,40 and 80 mg/L TVO,as well as high-glucose Dulbecco's modified Eagle's medium (DMEM) containing 1％ dimethyl sulfoxide (DMSO,control group),respectively.After 24-hour treatment,cell counting kit 8 (CCK8) assay was performed to estimate the proliferative activity of A431 cells in the above groups.Some other A431 cells were divided into 4 groups:control group treated with high-glucose DMEM containing 1％ DMSO,TVO group treated with 40 mg/LTVO,cisplatin group treated with 10 mg/L cisplatin,and TVO + cisplatin group treated with 40 mg/L TVO and 10 mg/L cisplatin.After 24-hour treatment,CCK8 assay was performed to estimate the cellular proliferative activity,inverted microscopy to observe changes in cell morphology,fluorescence microscopy to detect cell apoptosis after acridine orange (AO)/ethidium bromide (EB) double-staining,colorimetry to evaluate the activity of Caspase-3 and Caspase-9,and Western blot analysis to determine the protein expression of Caspase-3 and p-glycoprotein.Results After 24-hour treatment with 5,10,20,40 and 80 mg/L TVO,the cell proliferation rates were inhibited by (12.83 ± 6.4)％,(16.27 ± 11.4)％,(21.61 ± 9.1)％,(33.11 ± 2.0)％ and (46.00 ± 3.3)％ respectively,and the inhibition rates were all significantly higher in these groups than in the control group (4.03％ ± 1.4％,all P ＜ 0.05).The 50％ inhibitory concentration (IC50) of TVO at 24 hours was (61.66 ± 1.03) mg/L.Compared with the control group,the proliferation inhibition rates significantly increased in the TVO group,cisplatin group and TVO + cisplatin group (all P ＜ 0.05),suggesting that the combination of TVO and cisplatin showed synergistic inhibitory effects with a combination index of 1.366.Moreover,A431 cells turned round to different extents and became apoptotic in the TVO group and cisplatin group,and the TVO + cisplatin group showed obviously decreased number of cells and a large number of cell debris.The TVO + cisplatin group also showed significantly increased activity of Caspase-3 (1.520 ± 0.115) and Caspase-9 (2.760 ± 0.297) as well as protein expression of Caspase-3 (1.482 ± 0.016) compared with the TVO group (Caspase-3 activity:1.117 ± 0.095;Caspase-9 activity:1.259 ± 0.059;Caspase-3 protein expression:1.156 ± 0.006,all P ＜ 0.01) and cisplatin group (Caspase-3 activity:1.381 ± 0.089;Caspase-9 activity:1.829 ± 0.171;Caspase-3 protein expression:1.296 ± 0.021,all P ＜ 0.01),but significantly decreased p-glycoprotein expression (0.528 ± 0.014) compared with the TVO group (1.311 ± 0.011,P ＜ 0.01) and cisplatin group (1.169 ± 0.012,P ＜ 0.01).Conclusion TVO combined with cisplatin can synergistically inhibit the proliferation of A431 cells and induce cell apoptosis,which may be associated with activation of the caspase system and decreased expression of pglycoprotein.
