Objective To investigate the clinical effect of Bella in the treatment of gastric ulcer. Methods According to the different treatment methods will be January 2015-2017 year in March in our hospital 120 cases of patients with gastric ulcer group: control group was treated with amoxicillin + clarithromycin + omeprazole treatment, the observation group used amoxicillin + clarithromycin + ray Bela with before and after treatment; the two groups were observed for clinical symptom score changes, the level of IL-2/IL-6/CRP the incidence of adverse reactions, and the relevant data for comparative analysis. Results Amoxicillin + clarithromycin + ray was Bella (observation group) in the treatment of gastric ulcer is better than omeprazole + amoxicillin + clarithromycin (control group) treatment, clinical symptoms score changes better than the control group, IL-2/IL-6/CRP levels than the control group, the difference was statistically significant (P<0.05); two groups of patients the adverse reaction rate comparison, the difference was not statistically significant. Conclusion The gastric ulcer patients choose amoxicillin + clarithromycin + ray Bella with significant curative effect, can improve the clinical symptoms and IL-2/IL-6/CRP level of patients, and will not increase the incidence of adverse reactions, it is worthy of widely used in the treatment of patients with gastric ulcer.

Objective:To discuss the effect of non-invasive mechanical ventilation on acute lung injury with pathologic pregnancy.Methods:A clinical retrospective analysis was carried out to investigate 45 cases of acute lung injury in pathologic pregnancy treated by non-invasive mechanical ventilation in central ICU.Results:Forty-four patients of forty-five were cured (97.8%).Only one patient(2.22%) developed ARDS,and changed to be treated by invasive mechanical ventilation.Conclusion: Pathologic pregnancy is the high risk group of AIS.Using NIPPV early is an effective way to treat,with high success rate of emergency care.The keys of treatment are early diagnosis,early treatment and monitoring of the development of ARDS.

Objective:To investigate the hospital acquired pneumoma in ICU,including its morbidity rate,mortality rate,including factors,and pathogenic distribution and its drug resistance.Methods:A clinical retrospective analysis was carried out to investigate 40 cases of patients acquiring pneumonia in EICU.Results:Twenty-three of 40 cases (57.5%)died.Factors significantly predisposing hospital acquired pneumonia were tracheal intubations or tracheotomy(35%).Pathogenic bacteria Pseudomonas aeruginosa (35%) and Acinetobacter baumannii (20%) were found in most of 40 cases.And the analysis of drug sensitivity showed resistance among all the agents tested in different levels,also the multidrug resistance emerged.Conclusion:Mortality rate of HAP is found high in ICU.The leading causative microorganisms are Gram-negative bacteria,and drug-resistant bacteria.Antibiotics should be appropriately selected.

PurposeTo investigate the permeation of model drug,propranolol hydrochloride, through the excised porcine buccal mucosa. To study the influences of various factors on the buccal absorption also studied. MethodsUsing excised porcine buccal mucosa permeation test in vitro. By means of changing the medium pH, osmotic concentration, drug concentration, the concentration of various penetration enhancers including sodium glycodeoxycholate (GDC), sodium glycocholate (GC), dimethy1-β-cyclodextrin (DMβCD), and hydropropyl-β-cyclodextrin(HPβCD). The permeation rates and permeability coefficients(P) were determined and evaluated. The solubilities and apparent partition coefficients also determined in some tests. ResultsThe result showed that the P were increased when porcine buccal mucosae were pretreated with every penetration enhancement of certain concentration, increased as the pH of test solution rose from 4.9 to 9.1. The P remained constant as the concentration of propranolol hydrochloride increased from 5 to 80 mg/ml, decreased with the increasing of osmotic concentration Conclusions The absorption of propranolol hydrochloride through porcine buccal mucosa is a typical passive process, and affected by penetration enhancers, medium pH, osmotic concentration.

This report concerns an observation on the biological properties of orthomyxoviruses type A in the condition of symbiosis with streptococcus A in embryonated eggs. The results show that both the viruses and the streptococci multiply normally in the condition of symbiosis and that the activity of the virus neuraminidase enhances, with the speed of the virus disassociating from RBC increasing. The morphological changes of the virus were observed also by transmission electron microscopy. The reason of these changes is discussed,

With the ventilator associated lung injury (VALI) atracting more and more attention,lung protective ventilation strategy (LPVS) has gradually been applied to clinical practice.Obese patients are at higher risk in VALI for laparoscopic surgery,mechanical ventilation induced atelectasis is an important reason for low oxygen in intraoperative and postoperativen procedure.In laparoscopic surgery,high abdominal pressure causes the elevation of diaphragm,and increases airway pressure.The excessive pressure increases the amount of alveolar dead space and airway pressure,reduces lung compliance,and increases the possibility of barotrauma and colotrauma.In addition,carbon dioxide pnenmoperitoneum indces hypercapnia.Both of them influence the recovery of postoperative lung function.To optimize intraoperative management and improve the prognosis of patients with general anesthesia,the application of LPVS attracts more attention,including small tidal volume,positive end-expiratory pressure,and recruitment maneuvers,etc.However,LVPS may also cause lung injury.This article is a review on the application of LPVS in laparoscopic surgery of obese patients.

Objective To study the combination effectof curcumin and γray on the activity of human lung carcinoma NCI-H460 cells and explore the sensitization of curcumin to γray.Methods The NCI-H460 cells proliferation were detected by MTT,the cell cycle and apoptosis by flow cytometry.The expression of Bcl-2 and Bax were detected by Western Blot and the NF-κB gene expression by RT-PCR.In addition,the mice model of lung cancer was randomly divided into 4 groups:control group,curcumin group,γ ray group and combination group.After 28 days,the tumor volume was measured.Results The proliferation and cell cycle of NCI-H460 cells were inhibited and the apoptosis was increased in combination group.In addition,compared with curcumin group or γray group,the expression of Bcl-2 was inhibited,but the expression of Bax was increased and the mRNA expression of NF-KB was inhibited in combination group(all P＜0.05).Also in combination group the tumor volume was significantly inhibited compared with curcumin group or γ ray group(all P＜0.05).Conclusion Curcumin might induce the radiosensitivity of Human Lung Carcinoma NCI-H460 cells through the pathway.

Gastrointestinal bleeding in children is a potentially life threatening medical emergency requiring an appropriate diagnostic and therapeutic approach.The causes of hemorrhage are numerous and varies with age.The clinical presentation of gastrointestinal bleeding in children ranges from asymptomatic microcytic anemia to hypovolemic shock.Therefore,the primary focus in a child with gastrointestinal bleeding is rapid assessment,stabilization,and resuscitation followed by a diagnostic modalities.

Objective:To investigate the effects of the treatment of early cracked teeth with vital pulp preservation.Methods:63 early cracked teeth with vital pulp in 56 patients were treated by light cured composite resin filling with or without MTA rebasing,and restored by precious metal crown.The patients were followed up for 2 years.Results:After 2 years follow-up,57 teeth were successfully treated and failure was found in 6 teeth,the effective rate was 90.4％.Conclusion:Light cured resin filling directly or with MTA rebasing for early cracked teeth with vital pulp,and restoration by precious metal crown are effective in the treatment of early cracked teeth with vital pulp.

Laboratory education in basic medicine plays a significant part in medical education.By investigating and analyzing the recent laboratory education in basic medicine,it was found out that the teaching effect of recent laboratory education was basically appropriate.But there was still some deficiency in cultivating problem-solving capability and innovation thinking.
