Objective To investigate the morphologic abnormalities of myenteric plexus in diabetic rats and to explore the mechanism of its effect on gastrointestinal motility.Methods Thirty rats were randomly divided into diabetic group and control group.Gastrointestinal transit time was measured and histologic changes of cholinergic and nitriergic nerves in ileum myenteric plexus were observed with enzy- matic histochemistry.Results Four months after the establishment of the diabetic rats model,gastroin- testinal transit time was found delayed comparing with control group,the density of cholinergic neurons in the ileum myenteric plexus was decreased (P＜0.01) and the densities of nitriergic ganglions and neurons were significantly increased comparing with control group (P＜0.05 and P＜0.01).Conclu- sion Decrease of cholinergic nerves and increase of nitriergic nerves in the myenteric plexus of intestine is one of the mechanisms of delay gastrointestinal transit time in diabetic rats.

OBJECTIVETo observe the effect of Kanli Granule (KG) on myocardial mechanics in pressure overload induced diastolic heart failure (DHF) rats.

METHODSTotally 60 male Wistar rats were divided into the sham-operation group, the model group, the KG group, and the Valsartan group according to random digit table, 15 in each group. The pressure overload induced DHF model was established in all groups except the sham-operation group using abdominal aortic constriction surgery. Totally 7 rats died after modeling (with the mortality of 10. 67%) , and the rest 53 finished the following test. Rats in the KG group were administered with KG extract (calculated as 6. 75 g crude drug/kg) by gastrogavage. Rats in the Valsartan group were administered with Valsartan (7.2 µg/g) by gastrogavage. Equal volume of double distilled water was administered to rats in the model group and the sham-operation group by gastrogavage. All rats were intervened for 32 weeks. The response of isolated heart papillary muscle tonus to isoprenaline (ISO) and adenylate cyclase (Forskolin) was respectively observed. The enhancement phenomenon after resting development force (DF) of isolated heart papillary muscle tonus, and changes of DF in different Ca²⁺ concentrations were observed.

RESULTS(1) In the ISO response test: Compared with the sham-operation group, the amplifications of DF, ±df/dt, -df/dt were obviously elevated in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously lowered in the KG group (P < 0.01), and the amplification of ±df/dt was also reduced in the Valsartan group (P < 0.01). (2) In the Forskolin response test: Compared with the sham-operation group, the amplifications of DF and ±df/dt obviously increased in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously reduced in the KG group (P < 0.01), and the amplification of DF was also reduced in the Valsartan group (P < 0.05). (3) In post-resting DF enhancement test: Compared with the sham-operation group, the amplification of DF showed gradually decreasing tendency along with prolonged resting time in the model group, and they were obviously lowered at all time points (P < 0.05). Compared with the model group, the amplification of DF was gradually increasing along with prolonged resting time in the KG group. The amplification of DF at post-resting 240 s was obviously larger in the KG group than in the model group (P < 0.05). The amplification of post-resting DF still showed gradually decreasing tendency along with prolonged resting time in the Valsartan group, with increased amplifications of DF at post-resting 60 s and 120 s (P < 0. 05) (4) The amplifications of DF in different Ca²⁺ concentrations: Compared with the sham-operation group, the amplifications of DF were significantly elevated in different Ca²⁺ concentrations (1.75, 3.5, 7.0 mmol/L ) (P < 0.05, P < 0.01). Compared with the model group, there was no statistical difference in amplification of DF in different Ca²⁺ concentrations in the KG group (P > 0.05). The amplifications of DF in different Ca²⁺ concentrations were significantly reduced in the Valsartan group (P < 0.05).

CONCLUSIONSThe ISO response and the Forskolin response were enhanced in isolated heart papillary muscle tonus of pressure overload induced DHF rats; enhanced post-resting DF was reduced; DF in different supra-physiologic levels of Ca²⁺ was still enhanced. KG could significantly improve excessive enhancement of pressure overload induced DHF rats in ISO response and Forskolin response, and improve enhancement of post-resting myocardium.

Objective Blood pressure variability (BPV) is an independent risk factor for the death of patients with maintenance hemodialysis (MHD).There is no study on the influencing factors of BPV at home in HD patients in China.The article aimed to investigate MHD patients'BPV at home and related influencing factors in order to provide theoretical basis for reducing home BPV (HBPV) clinically. Methods We chose 103 patients who were treated with MHD in the Renal Medicine Room of Nephrology Department in three upper first -class hospitals including Jiangsu Provincial People 's Hospital, the First Affiliated Hospital of Suzhou University and the Affiliated Hospi -tal of Jiangsu University from March 2017 to October 2017.We col-lected their 7 days'blood pressure monitoring at home and blood pressure before dialysis, average value and standard deviation in sys -tolic blood pressure monitoring at home, and took the coefficient of variation of systolic blood pressure as the expression of HBPV .The patients were divided into high BPV group (BPV≥5.8％) and low BPV group (BPV<5.8％) according to the average BPV.At the same time, we recorded indexes such as sex , age, dialysis age, primary disease, BMI, inter-dialytic weight gain (IDWG), left ven-tricular mass index(LVMI) and analyzed relative influencing factors by multiple linear regression . Results The age, IDWG and LV-MI were positive independent influencing factors of HBPV (R 2 =0.467,F=10.945,P<0.001).According to standardized regression co-efficient, the contribution of each variable to HBPV was as follows : PIBWG >Age>LVMI. Conclusion In clinical nursing, we should actively control the IDWG of patients , encourage patients to monitor their blood pressure at home , and increase their awareness of the importance of home BPV.Meanwhile, HBPV is an important index for predicting left ventricular hypertrophy and can be used as an objective tool to improve patients 'self-management ability.

Objective To investigate the effect of different concentrations of vinorelbine on apoptosis ,telomerase ac-tivity and expression of human telomerase-reverse transcriptase gene ( hTERT ) in human epithelial ovarian cancer cells SKOV3.Methods Ovarian cancer cells SKOV 3 were treated with vinorelbine under different concentrations . The cell proliferation was measured by cell counting kit-8 ( CCK-8) assay , and the cell apoptosis was detected by flow cytometry.The telomerase activity of SKOV3 cells was determined by TRAP-PAGE-silver staining;The mRNA expression of hTERT was performed by RT-PCR assay .Results Vinorelbine could significantly inhibited the prolifer-ation of SKOV3 cells,induce cell apoptosis (P<0.01),reduce the telomerase activity and expression of hTERT mRNA (P<0.01), in dependent of a concentration-time manner.Conclusions The detection of telomerase activity and the mRNA expression of hTERT might be vital for predicting the prognosis of patients with epithelial ovarian cancer .
