Objective:To study the effects of cisapride on digestive symptoms and gastrointestinal hormones in elderly peritoneal dialysis patients.Methods:Forty-two elderly patients with renal failure undergoing peritoneal dialysis in our hospital from July 2017 to December 2017 were randomly selected as the study group.Meanwhile, 20 healthy elderly people in the corresponding time period were selected as the control group.Control group received continuous ambulatory peritoneal dialysis(CAPD)and other conventional basic therapy, and study group received cisapride as add-on therapy to treatment for control group.Serum levels of somatostatin(SS), motilin(MOT)and vasoactive intestinal peptide(VIP)were compared between the two groups.Gastrointestinal symptoms, serum levels of gastrointestinal hormones and biochemical indexes were compared before and after treatment in the study group.Results:The score of acid reflux, nausea, abdominal distension, belching and constipation were lower in the study group after treatment than before treatment( t=4.42, 4.32, 6.80, 6.29 and 6.76, all P=0.00). Before treatment, levels of MOT, SS and VIP were higher in the study group than in the control group[(636.65±32.02)pmol/L vs.(228.47±28.74)pmol/L, (64.02±16.32)mg/L vs.(42.38±6.42)mg/L, (118.64±17.68)ng/L vs.(58.62±11.63)ng/L, t=48.44, 7.47 and 15.93, all P=0.00]. The level of MOT was lower after than before treatment[(385.36±19.64)pmol/L vs.(636.65±32.02)pmol/L, t=43.36, P=0.00], and the levels of SS and VIP had no significant difference before versus after treatment( t=-0.11 and -0.42, P=0.91 and 0.68). After treatment, the level of MOT was still higher in the study group than in the control group[(385.36 ±19.64)pmol/L vs.(228.47 ±28.74)pmol/L, t=22.08, P=0.00]. There was no significant difference in blood urea nitrogen(BUN), creatinine, haemoglobin and kt/v levels between before and after treatment( P>0.05). The level of albumin(ALB)was higher after than before treatment[(38.60±1.89)g/L vs.(37.71±1.96)g/L, t=2.12, P=0.04]. Conclusions:Gastrointestinal symptoms are common in elderly patients with peritoneal dialysis, and the accumulation of gastrointestinal hormones is obvious, which leads to gastrointestinal dysfunction.The conventional treatment in combination with cisapride can improve gastrointestinal symptoms and reduce serum MOT level in these patients.

Objective:To research the correlation between the cobamamide photodegradation products in the visible light area at different wavelengths and the photodegradation rate intensity. Methods:The 40-minute illumination experiment was conducted for co-bamamide reference solution respectively at the wavelength of 400 nm,450 nm,500 nm,550 nm,600 nm,650 nm and 700 nm under the illumination of 50 Lx,100 Lx,200 Lx,300 Lx,400 Lx and 500 Lx,respectively. An HPLC method was used to detect the cobam-amide content after the irradiation, the contents and proportions of hydroxocobalamin and adenosine (two photodegradation products) were calculated and the two photodegradation products were confirmed by mass spectrum. Results:The main photodegradation products of cobamamide (impurity 1,adenosine and hydroxocobalamin) had the similar photodegradation tendency. Within the scope of 50 Lx-200 Lx,the illumination intensity affected the concentration ratio of hydroxocobalamin and adenosine obviously. Within the scope of 200 Lx-500 Lx,the illumination intensity showed smaller effect. Under the different wavelengths and photodegradation rate intensity, the content of hydroxocobalamin was higher than that of adenosine under the same experimental condition.Conclusion:This paper re-searched the cobamamide photodegradation products in the optimum dark condition. The method is accurate and reliable,which can be used for the control of photodegradation related substances of cobamamide.

Delayed hemothorax after blunt torso injury is rare, but might be associated with significant morbidity and mortality. We present a case of delayed hemothorax bleeding from phrenic artery injury in a 24-year-old woman. The patient suffered from multiple rib fractures on the right side, a right hemopneumothorax, thoracic vertebral injury and a pelvic bone fracture after a fall from a fourth floor window. Delayed hemothorax associated with phrenic artery bleeding, caused by a stab injury from a fractured rib segment, was treated successfully by a minimally invasive thoracoscopic surgery. Here, we have shown that fracture of a lower rib or ribs might be accompanied by delayed massive hemothorax that can be rapidly identified and promptly managed by thoracoscopic means.

BACKGROUND: We conducted this study to verify whether a mechanical ventilator is adequate for cardiopulmonary resuscitation (CPR). METHODS: A self-inflating bag resuscitator and a mechanical ventilator were used to test two experimental models: Model 1 (CPR manikin without chest compression) and Model 2 (CPR manikin with chest compression). Model 2 was divided into three subgroups according to ventilator pressure limits (P(limit)). The self-inflating bag resuscitator was set with a ventilation rate of 10 breaths/min with the volume-marked bag-valve procedure. The mode of the mechanical ventilator was set as follows: volume-controlled mandatory ventilation of tidal volume (Vt) 600 mL, an inspiration time of 1.2 seconds, a constant flow pattern, a ventilation rate of 10 breaths/minute, a positive end expiratory pressure of 3 cmH2O and a maximum trigger limit. Peak airway pressure (P(peak)) and Vt were measured by a flow analyzer. Ventilation adequacy was determined at a Vt range of 400-600 mL with a P(peak) of < or = 50 cmH2O. RESULTS: In Model 1, Vt and P(peak) were in the appropriate range in the ventilation equipments. In Model 2, for the self-inflating bag resuscitator, the adequate Vt and P(peak) levels were 17%, and the P(peak) adequacy was 20% and the Vt was 65%. For the mechanical ventilator, the adequate Vt and P(peak) levels were 85%; the P(peak) adequacy was 85%; and the Vt adequacy was 100% at 60 cmH2O of P(limit). CONCLUSIONS: In a manikin model, a mechanical ventilator was superior to self-inflating bag resuscitator for maintaining adequate ventilation during chest compression.

BACKGROUND: Early prediction of neurologic outcome is important to patients treated with therapeutic hypothermia after hypoxic brain injury. Hypoxic brain injury patients may have poor neurologic prognosis due to increased intracranial pressure. Increased intracranial pressure can be detected by optic nerve sheath diameter (ONSD) measurement in computed tomography (CT) or ultrasound. In this study, we evaluate the relation between neurologic prognosis and optic nerve sheath diameter measured in brain CT of hypoxic brain injury patients. METHODS: We analyzed the patient clinical data by retrospective chart review. We measured the ONSD in initial brain CT. We also measured and calculated the gray white matter ratio (GWR) in CT scan. We split the patients into two groups based on neurologic outcome, and clinical data, ONSD, and GWR were compared in the two groups. RESULTS: Twenty-four patients were included in this study (age: 52.6 +/- 18.3, 18 males). The mean ONSD of the poor neurologic outcome group was larger than that of the good neurologic outcome group (6.07 mm vs. 5.39 mm, p = 0.003). The GWR of the good neurologic outcome group was larger than that of the poor outcome group (1.09 vs. 1.28, p = 0.000). ONSD was a good predictor of neurologic outcome (area under curve: 0.848), and an ONSD cut off > or = 5.575 mm had a sensitivity of 86.7% and a specificity of 77.8%. CONCLUSIONS: ONSD measured on the initial brain CT scan can predict the neurologic prognosis in cardiac arrest and hanging patients treated with therapeutic hypothermia.
