In recent years, according to the etiology and pathology researches of slow transit constipation (STC) STC is considered as a kind of "enteric neuropathy", indicating it is a kind of disease caused by abnormity of the enteric nervous system (ENS). Through reviewing the mechanism of acupuncture to regulate STC, it is found out that there is a close relationship between acupuncture regulating STC and ENS. Through various channels including ganglion cells, nerve plexus, neurotransmitter and TRPV1 (the primary sensory neurons receptor of the ENS) of the ENS, acupuncture is likely to make comprehensive adjustment on STC.

Objective To investigate the status quo of nursing lack in level three first-class hospitals of Zhongshan city,and analyze the relevant reasons.Methods A sample of 765 nurses in 4 tertiary general hospitals completed the modified Missed Nursing Care Survey.Results Assessment,planning,intervention and evaluation were reported to be missed by 9.86％～39.04％,12.05％～44.38％,3.29％～46.85％ and 12.19％～22.05％ of the survey respondents respectively.Reasons for missed care were lack of labor resources(85.48％～93.84％),lack of material resources(80.00％～80.96％),low efficiency of the team (78.08％～86.58％),poor work habits (70.95％～83.84％),and improvement of patients’ needs (88.90％～93.01％).Conclusions Lack of care is widespread,and the degree of lack of each link is different.Reasons lead to the lack of care of nursing staff are higher patients’ demands to nursing work,shortage of nursing staff and unplanned surge of patients’ number.

Objective To observe the effects of fosinopril(FOS),a new generation angiotensin-converting enzyme inhibitor(ACEI),on protein and mRNA expression of transforming growth factor-?_1(TGF-?_1) of rat glomerular mesangial cell(GMC) induced by lipopolysaccharide(LPS);to demonstrate the preventive mechanism against glomerular sclerosis by applying FOS.Methods The cultured GMC in classic way were divided into 3 groups:control group;LPS group;LPS+FOS group.TGF-?_1 concentration in GMC supernatant fluid was detected by ELISA;TGF-?_1 mRNA expression was determined by semiquantitative real-time RT-PCR.Results LPS group was obviously higher than control groups in TGF-?_1 secretion and mRNA expression,while LPS+FOS group decreased distinctively in TGF-?_1 secretion and mRNA expression compared with LPS group.Conclusions FOS has obviously inhibited on TGF-?_1 expression of rat GMC both at protein level and mRNA level,which reveals that it may be an important mechanism by FOS on restraining the development of glomerulosclerosis.

Objective To evaluate effects of trichostain A (TSA) on cell proliferation, cell cycles, apoptosis and invasiveness of multiple myeloma cell line U266; as well as active changes of methylation regulating proteins including DNA methyl-transferase(DNMTs), methyl-binding domain (MBD) proteins: MBD2 and MeCP2 after treated with TSA. Methods U266 cells were treated with different concentrations of TSA for 12, 24, 48 and 60 h. The proliferation activity of U266 cells was detected by MTT and the IC50 of 24 h was calculated. After U266 cells were treated with IC50, cell cycles were check out by dying with PI. mRNA of matrix metalloproteinase-2(MMP-2), bc1-2, bcl-xl and methylation regulating proteins (DNMTs, MBD2 and MeCP2) were detected by real-time PCR. FCM and Western blotting were used to measure expressions of MMP-2 and MBD2. Results MTT results revealed TSA inhibited proliferation of U266 cells in a dose-and time-dependent manner and the IC50 of 24 h was 0.07 μmol/L FCM analysis showed that TSA could arrest the cell cycle in G0/G1 and the proliferation index (PI) in U266 cells [(49.90 0.39)%]were significantly different after exposed to TSA (0.7 μmnol/L for 24h compared with that in the control cells[(55.78 0.49)%](P <0.01). After treated by TSA, the 2-△△Ct of MMP-2, bcl-2 and bcl-xl were 0.71 0.06, 5.04 0.92 and 2.95 0.35, respectively. There were great changes on mRNA of DNMT, MBD2 and MeCP2. TSA could reverse the transcription of DNMT, MBD2 and MeCP2. Conclusion TSA can arrest the U266 cell cycle in GVG, to prevent its proliferation and promote apoptosis, which maybe greatly connect with the changes of the methylation regulating proteins.

Objective To investigate the clinical effect of preoperative nutritional treatment and perioperative nutrition support for the patients with esophageal cancer.Methods According to the digital table,90 patients with esophageal cancer were divided into the control group(15 cases),preoperative nutrition group(25 cases),postoperation nutrition group(25 cases)and preoperative nutrition + postoperation nutrition group(25 cases).The postoperative quality of life and the complications were compared.Results Postoperative quality of life in the preoperative nutrition group,postoperation nutrition group and preoperative nutrition + postoperation nutrition group were all better than that in the control group(t =14.76,15.13,17.87,all P ＜ 0.05).The incidence rate of postoperative complications in patients received nutritional intervention significantly decreased than in the control group(x2 =9.17,12.13,19.18,all P ＜ 0.05).Conclusion The preoperative nutrition and postoperation nutrition can improve the postoperative quality of life and reduce the incidence rate of the complications.

0.05). Conclusion Ryanodine receptor of asthmatic guinea-pig showed hypersensitivity. Under specified condition, the characteristics of ryanodine receptor still retains in subcultured ASMCs of asthmatic guinea-pig.
