Parenteral nutrition associated cholestasis (PNAC) mainly occurs in children. Currently identified risk factors include premature infants, lack of enteral feeding, repeated infections, and toxicity or nutrient deficiency of parenteral nutrition solution. Recent studies have shown that nuclear receptor-mediated bile acid transporter may be the key site of PNAC pathogenesis, in which some cytokines play important roles. New anti-cholestatic therapy based on the regulation of expression of these molecules may prevent end-stage liver disease caused by PNAC.

To explore the cognitions and behavior of cough etiquette of 556 residents in Longhua Community and self-compare the changes of cognitions and behavior before and after health education and training.The results showed that awareness rate of cough etiquette was low before training (senior group:25.4％,children:11.9％,young white-collar:36.1％,immigrants:14.3％,P ＜ 0.05) and increased significantly (senior group:97.2％,children:99.2％,young white-collar:100.0％,immigrants:98.6％,P ＜ 0.05).Except for no difference in compliance aspects of immigrants (P ＞ 0.05),the other three groups improved after training.And the difference was statistically significant before and after training (P＜0.05).

Objective To study the curative effect and medchanism of action about prostaglandin E1 and magnesium sulfate in the treatment of chronic pulmonary heart disease in the aggravation period. Methods Fifty-three patients with chronic pulmonary heart disease in the aggravation period were accepted emergencyward in the Guangzhou Red Cross Hospital during June 2007 to May 2008,they were randomly divided into the treatment group (28 case) and control group (25 case) . Both groups were given low flux breathe in oxygen and dissipate phlegm and relieve a cough and resist infection and spasmo]ysis and calm down asthma and strive heart and diuresis colligate therapy. Mean while,patients in the treatment group,beside the colligate therapy,were treated with prostaglandin E1 10 ml and magnesium sulfate 10 ml ,the course of treatment lasted 2 weeks. Then we investigate the amelioration of clinical symptom and alteration of blood gas analysis in the two groups before and after the treatment. Results The rate of clinical efficacy were 89.3% (25/28) and 76.0% (18/25),with superiority in the treatment group (χ2=1.87,P<0.05) . Whole blood viscosity,fibrinogen,PaO2 and PaCO2 were improved in both groups,amelioration of blood gas analysis observation superiority in the treatment group compared with control group (P<0.05). Conclu-sions Prostaglandin E1 and magnesium sulfate can depress pulmonary artery pressure and abate the afterload of right ventricle,which have better treatment effect in chronic pulmonary heart disease in the aggravation period.

Objective To investigate the therapeutic effect of bundle treatments for critically ill patients with pulmonary tuberculosis and respiratory failure (RF).Methods A prospective study was conducted, including 56 patients with pulmonary tuberculosis and RF necessary for invasive mechanical ventilation admitted into Department of Critical Care Medicine of the Fourth People's Hospital of Nanning City from January 2013 to December 2014 as the observation group to be treated by bundle treatments. A series of treatments and cares were given to the critically ill patients, such as invasive mechanical ventilation, application of antibiotics by experience within the first hour, supportive treatment targeted to hemodynamics in early stage, correction of brain dysfunction, effective therapy for tuberculosis, establishment of enteral nutrition in early stage and prevention of ventilator-associated pneumonia (VAP), etc. All the above treatments were completed one by one in 6 hours to 12 hours. Meanwhile, 42 patients who hospitalized from January 2011 to December 2012 and treated with conventional targeted therapy were designed as the control group. The changes of vital signs, blood routine test, respiration, liver, kidney, etc organ functions, the improvement of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, expected mortality and sequential organ failure assessment (SOFA) score, the incidence of VAP, cure and improvement rate, mortality, duration of invasive mechanical ventilation, the length of stay in intensive care unit (ICU) were compared between the two groups after treatments.Results There were no statistically significant differences in the comparisons between the two groups before and after treatments in temperature, white blood cell count (WBC), blood glucose, total bilirubin (TBil), alanine transaminase (ALT), albumin (Alb) and cholesterol level (allP > 0.05), except the platelet (PLT) count in observation group was higher than that in control group before treatments. After treatments for 72 hours, in the two groups, the heart rate (HR), respiration rate (RR), APACHE Ⅱ score and expected mortality were lower than those before treatments, while the arterial partial pressure of oxygen (PaO2) and oxygenation index were higher than those before treatments. There were no statistically significant differences in pH value, PLT, arterial partial pressure of carbon dioxide (PaCO2) and SOFA score before and after treatments in the control group (allP > 0.05). In the observation group, after treatments, the pH value was increased compared with that before treatments, while PLT, PaCO2 and SOFA score were decreased compared with those before treatments (allP < 0.05). The degrees of improvement of PaCO2 and oxygenation index in the observation group were superior to those in the control group [PaCO2 (mmHg, 1 mmHg = 0.133 kPa): 43.32±9.10 vs. 56.10±9.39, oxygenation index (mmHg): 330.60±100.98 vs. 245.65±83.20, bothP < 0.05]. After bundle treatments, compared with control group, the incidence of VAP was decreased [16.07% (9/56) vs. 33.33% (14/42),P < 0.05], improvement and cure rate was increased [78.57% (44/56) vs. 59.52% (25/42),P < 0.05] and mortality was decreased significantly in observation group [10.71% (6/56) vs. 28.57% (12/42),P < 0.05]. The duration of invasive mechanical ventilation (days: 9.15±3.59 vs. 16.96±13.44) and the length of stay in ICU (days: 13.30±4.24 vs. 23.00±15.03) in the observation group were shorter than those in the control group, but no statistically significant differences were found (bothP > 0.05).Conclusion The bundle treatments can effectively reduce the incidence of VAP and elevate the improvement and cure rate in patients with pulmonary tuberculosis complicated with RF.

Objective To investigate the suppressive effects of Maytansine on the proliferation,migration and invasion of nasopharyngeal carcinoma (NPC) cells.Methods MTT assay was employed to study the effect of Maytansine on the viability of 5-8F and SUNE1 cell lines.Wound healing assays and transwell were used to assess the effects of Maytansine on the migration and invasion capacities of NPC cells.Furthermore,an integrated bioinformatics analysis was conducted to clarify the potential mechanisms of Maytansine.Results Time course analysis of Maytansine treated NPC cells indicated significant decrease in cell viability,assessed by MTT.Furthermore,we identified that Maytansine reduced the migration and invasion capacities of NPC cells.Moreover,bioinformatics analysis showed that Maytansine suppressed the proliferation,migration and invasion via the upregulation of CDKN1B,BMP2,HBEGF,SMAD6,ADM,VEGFA,CTGF and IL6 in NPC cells.Conclusion Maytansine plays a significant suppressive role in the proliferation,migration and invasion of NPC cells and may be explored further for its potential therapeutic effects on NPC in humans.

AIM: To study the efficacy and safety of Ultra Q- YAG vitreolysis for vitreous floaters.
METHODS: Retrospective case series study. From September 2014 to May 2015 in Beijing Aier - Intech Eye Hospital, 263 cases (340 eyes) with vitreous floaters were involved. All patients underwent visual acuity, intraocular pressure, slit lamp, mydriatic fundus, B ultrasonic examination, and recorded the form of a vitreous opacity excluded pathological fundus lesions. All the patients were divided into two groups: Group A (<30 years old) 78 cases (82 eyes); the morphology of vitreous opacity were dot, filiform and mesh. Group B ( > 45 years old), 185 cases (258 eyes), the morphology of vitreous opacity was Weiss ring, translucent flocculent clouds or dense fibrous membrane. Patients in 30 - 45 years old were eliminated because of the untypical opacity factor. The treatment was done by the same physician. Vision changes was analyzed before and after the treatment.
RESULTS: Questionnaire survey was done. According to the scores of the questionnaires, patients were divided into 3 groups: no improvement ( 1 - 2 points), partial improvement (3-5 points), significant improvement (6-10 points ). At 1mo after treatment, Group A: no improvement in 9 eyes (11. 0%), partial improvement in 57 eyes (69. 5%) and significant improvement in 16 eyes (19. 5%); Group B: no improvement in 0 eyes, partial improvement in 23 eyes ( 8. 9%) and significant improvement in 235 eyes (91. 1%); all the patients had no complications.
CONCLUSION: The treatment with YAG vitreolysis for vitreous floaters is safe and effective, especially for the patients more than 45 years old whose vitreous floaters caused by posterior vitreous detachment.
