Objective To investigate the clinical efficacy of Wumei Wan (Fructus Mume Pills) for diabetic gastroparesis with the syndrome of cold-heat mixture. Methods Sixty-eight diabetic gastroparesis patients with the syndrome of cold-heat mixture were evenly randomized into treatment group and control group. On the basis of treatment for controlling the blood glucose level, the treatment group was given oral use of Wumei Wan and the control group was given oral use of Cisapride. After treatment for one month, the therapeutic effect of both groups was evaluated, and the changes of gastrointestinal symptoms, gastric emptying, 2-hour postprandial glucose(2hPG), glycosylated hemoglobin(HbA1c), and fasting plasma glucose(FPG) in both groups were also observed. Results (1)The total effective rate of the treatment group was 88.24%, and that of the control group was 67.65%, the difference being significant(P<0.05). (2 ) After treatment , the scores of gastrointestinal symptoms of nausea and vomiting, gastric fullness, anorexia, belching and acid regurgitation, abdominal and gastric pain, diarrhea, and constipation in the treatment group were markedly improved(P<0.05 or P<0 . 01 compared with those before treatment ). In the control group, symptom relief was shown in nausea and vomiting, anorexia, and diarrhea(P<0.05). The treatment group had better effect on relieving nausea and vomiting, abdominal and gastric pain, diarrhea, and constipation than the control group(P<0.05 or P<0.01). (3)After treatment, 2hPG, FPG and HbA1c levels were obviously decreased in both groups(P<0.05 compared with those before treatment) , and the decrease in the treatment group was superior to that in the control group (P<0.05). (4)After treatment, half gastric emptying time, full gastric emptying time, and the contraction of gastric antrum were improved in both groups(P<0.05), and the improvement of gastric emptying in the treatment group was superior to that in the cont rol group(P<0.05). Conclusion Wumei Wan has better effect for the treatment of diabetic gastroparesis than western medicine Cisapride.

Objective To evaluate the effectiveness of noninvasive positive pressure ventilation(NPPV) as a weaning strategy in patients with acute respiratory failure after failure to wean from invasive positive pressure ventilation(IPPV). Method A prospective randomized and controlled clinical trial of weaning of IPPV was carried out in patients mechanically ventilated in mode of IPPV for more than 48 hours with failure in a spontaneous breathing trial(SBT: PSV 6 cmH_2O). Patients with contraindications to NPPV were excluded. After failure the SBT, patients were randomly divided(random number) in two groups. Patients in NPPV group were extubated after being ventilated with high pressure support for 30 minutes and then placed on NPPV. Patients in IPPV group were weaned following conventional procedure. Arterial blood gases, maximal inspiratory pressure, respiratory rate,tidal volume, rapid shallow breathing index, heart rate, arterial blood pressure, and peripheral oxygen saturation were measured before and after failing the SBT. The rate of complications, including pneumonia and tracheotomy duration mechanical ventilation, days of hospital stay and outcome were observed. Findings of the two groups were vompared using the Student t test and the chi-square test. Results The percentage of complications in the NPPV group was lower(22.9% versus 72.2%, P <0.01) ,with lower incidences of pneumonia(6.1%,36.1%; P <0.01) and tracheotomy. Compared between the two groups, days of ICU stay( 14.16(3.45) d vs. 22.57( 7.71 ) d; P <0.01) and total days of mechanical ventilation(14.88±3.76 days vs. 20.68± 2.79 days, P <0.01) of NPPV group are shorter than IPPV group. Conclusions NPPV is a good alternative to the mechanically venti-lated patients who fail in initial weaning attempts. The key to successful NPPV weaning is the proper selection of weaning candidates and using NPPV as soon as possible after extubation.

Objective To evaluate the predictive performance of diaphragm thickening fraction ( DTF) assessed by ultrasound in the feasibility of weaning from mechanical ventilation in patients with chronic obstructive pulmonary disease ( COPD ) . Methods Forty-three patients with COPD were enrolled for prospective study.All patients were ventilated mechanically for more than 48 hours and were expected to be weaned when they met clinical criteria in the intensive care unit from February 2015 to August 2015.Patients received a spontaneous breathing trial under pressure support for 1 h.At the end of spontaneous breathing trial, the right hemi-diaphragm was visualized in the zone of apposition using a 6-13 MHz linear ultrasound probe. Diaphragm thickness was recorded at end-inspiration (DTei) and end-expiration (DTee), and the DTF was calculated as percentage from the following formula:(DTei -DTee) /DTee.Also the rapid shallow breathing index ( RSBI ) was calculated.Patients meeting weaning criteria were extubated.Weaning successfully was defined as spontaneous breathing for >48 h without any form of ventilation support.Results Twenty-five patients were weaned successfully and failure of weaning was found in 18 patients.A significant differences in DTF ( 39.66 ±13.22 )%vs.( 23.84 ±8.85 )%, P <0.05 and RSBI ( 62.74 ±26.05 ) vs.( 98.89 ± 35.44) , P <0.05 were observed between patients with successful weaning and patients with failure.The sensitivity and specificity of DTF≥30 % for successful weaning were 84% and 83.88 %, respectively.The area under the receiver operating characteristic curve was 0.872 ( 95 % CI: 0.759-0.985 ) for DTF.By comparison, when RSBI was ≤105, there was a sensitivity of 92 %, and a specificity of 38.89 % for determining successful weaning.The area under the receiver operating characteristic curve was 0.804 ( 95 %CI: 0.669-0.940) for RSBI. Conclusions This study shows that in a cohort of COPD patients, the assessment of DTF using diaphragm ultrasound may be useful to predict success weaning or failure during spontaneous breathing trial.

Objective:To study the effects of ~(125)I-(α_v)ASODN on the in vitro invasive ability of heptocellular carcino-ma cell line(HepG2) through PEI-RGD-mediated receptor process. Methods: Intergrin α_v-specific antisense oligonucle-otide was labeled with ~(125)I, and PEI-RGD/~(125)I-(α_v)ASODN complex was prepared by combining ~(125)I-(α_v)ASODN with polyethyleneimine derivative PEI-RGD. PEI-RGD/~(125)I-(α_v)ASODN complex was transferred into HepG2 cells through the receptor-mediated process. The effect of PEI-RGD/~(125)I-(α_v)ASODN complex on the invasive ability of HepG2 cells was examined by Boyden chamber invasive assay. Results: (1) The labeling yield and radiochemical purity of ~(125)I-(α_v) ASODN were(73.78±4.09)% and(96.68±1.38)%, respectively, and the labeled compound had a good stability in vitro after 48 h at 37℃; (2) The ability of HepG2 cells to uptake PEI-RGD/~(125)I-(α_v)ASODN reached its peek ([12.77±0.85] % ) when PEI-RGD/~(125)I-(α_v)ASODN was at 4 μl/2 μg ([12.77±0.85] %), and then gredually decreased thereafter. So the dosage of PEI-RGD/~(125)I-(α_v)ASODN for the following experiment was chosen as 2 μl/1 μg; (3) The invasive capacity of HepG2 cells was significantly reduced in PEI-RGD/~(125)I-(α_v)ASODN group compared with those in other experiment and control groups (P <0.01 ). Conclusion: ~(125)I-(α_v)ASODN mediated by PEI-RGD can effectively inhibit the invasive capacity of HepG2 cells.

[Summary] The characteristics ot clinical data and relevant inspection (quantitative sensory and electrophysiological studies) in 5 patients hospitalized with acute painful neuropathy following rapid glycaemic control with insulin from 2010 to 2012 in our hospital were analyzed.The results showed that 5 patients were all males,aged 31-49 years,with lower body mass index,and diagnosed as latent autoimmune diabetes of adults (LADA) or type 2 diabetes.Glycaemic control was poor before application of insulin.When insulin was used,the hyperglycemia was rapidly corrected in a short time,with recurrent episodes of hypoglycemia during insulin treatment.The painful neuropathic symptoms appeared within 2-4 weeks after application of insulin,and were relieved partially or completely after 2-6 months.Neuropathic symptoms manifested as tingling and tenderness,with worsening during night and after insulin injection.The neuropathic symptoms were not significantly alleviated after application of neurotrophic drugs such as methycobal,protogen,and prostaglandin.These patients often suffered from severe anxiety.Nerve electromyogram examination showed slowed or normal motor conduction velocity of tibial and fibular nerves,and normal feeling threshold.

Objective To explore the protective effect of resveratrol against oxidative damage to cultivated fibroblasts irradiated with UVB. Methods Fibroblasts from normal human skin cultured in vitro were divided into 5 groups (a normal control group, a group irradiated with UVB, a group treated with resveratrol before UVB irradiation, and a group treated after irradiation). A monolayer of fibroblasts was irradiated with UVB at 60 mJ/cm2. The vitality of the cells was measured using the methylthiazol tetrazolium (MTT) method. The activity of superoxide dis-mutase (SOD) and malondialdehyde (MDA) content were determined using enzyme biochemistry. Results Resveratrol over 100 μM inhibited the proliferation of fibroblasts. Resveratrol under 100 μM improved the proliferation of cells. The optimal concentration was 50 μM. UVB irradiation decreased the vitality of the cells and SOD activity, and it significantly enhanced MDA content. Conclusions Resveratrol treatment before or after UVB irradiation elevates the survival rate of fibroblasts, enhances the activity of SOD, and decreases MDA content. Resveratrol at low concentration could improve the proliferation of fibroblasts, and at high concentration could inhibit their proliferation. Res-veratol at 50 μM relieves the inhibited proliferation of fibroblasts damaged by UVB irradiation.
