Objective:To evaluate the therapeutic effects and pharmacoeconomic results of four proton-pump inhibitors in the duo-denal ulcer patients with hemorrhage. Methods:Using a retrospective analysis, 90 duodenal ulcer patients with hemorrhage were in-volved. According to the proton pump inhibitors, there was no statistic difference among those groups(P>0. 05). The mean time to stop bleading,hemostalsis rate,and the incidance of adverse drug reactions of those four groups,there were no statistic differece too( P>0. 05). The cost of pantprazole group was much lower than the other three groups by cost-minimication analysis. Results:The effective rate of the four groups was 80. 0%, 86. 7%, 90. 0% and 90. 0%, respectively;there was no statistic difference among those groups(P>0. 05). The mean time to stop bleeding, hemostasis rate, and the incidence of adverse drug reactions of those four groups, there were no statistic difference too(P>0. 05). The cost of pantoprazole group was much lower than the other three groups by cost-minimization alanysis. Conclusion:The effect and safety of the four groups were basically equivalent, while the coot of pantoprazole is lowest, it is the best treatment plan by pharmacoeceonomics.

Objective To impove the cognition of allergic bronchopulmonary aspergillosis by analyzing its clinical characteristics.Methods 22 patients diagnosed as having allergic bronchopulmonary aspergillosis in our hospital were studied in their clinical characteristics,imaging findings,laboratory inspections,pathologies,therapies and follow-up results.Results (1)The patients consisted of 13males and 9 femailes.Asthma was present in 16 patients,and absent in 6 cases,some of which had no wheezing heard in lung auscultation.(2)Central bronchiectasis was present in 19 cases,with the upper lobe bronchial mainly involved.(3)Simple glucocorticoid therapy was used in 2 cases,the joint anti-fungal therapy in 19 cases(one case improved combined with itraconazole therapy after recurrence and one case improved with the joint itraconazole treatment,followed by recurrence of the symptoms after discontinued antifungal therapy and by the combination therapy again).Conclusion Clinical asthma is the most common symptom of ABPA.However,there are one-third of cases without history of asthma.Central bronchiectasis with formation of mucus suppository is a characteristic feature of ABPA which can prompt diagnosis and help in the prognosis.The combination of antifungal treatment can lead to improvement and reduce or eliminate the need of glucocorticoid therapy.

Objective: To investigate the expression and clinical significance of Ezrin, a tumor metastasis related gene, in tissues of nasopharyngeal carcinoma (NPC). Methods: The expression of Ezrin was detected with two-step immunohistochemistry technique in tissues of 38 NPC patients and 20 nasopharyngitis patients. All of the Ezrin expression and clinical data (gender, age, clinical stage, recurrence, and ]ymphonode metastasis) were compared and analyzed between two groups. Resuits: The Ezrin expressions were significantly different between NPC tissue (and peri-NPC tissue) and naeopharyngitis tissue (P＜0.05). No significant difference was found in the Ezrin expressions between the NPC tissue and the peri-NPC tissue (P＞0.05). It was found by Spearman analysis method that the Ezrin expression increased with patients' age (P＜0.05), but no significam relationship with gender, clinical stage, recurrence, and lymphonode metastasis (P＞0.05). The Ezrin expression influenced the survival time of NPC patients significantly (P＜0.01). Conclusion: The Ezrin expression can be an useful prognostic factor for NPC patients.

Objective To construct a luciferase reporter plasmid containing interferon regulatory factor 3(IRF-3)human gene promoter and to evaluate promoter activity in human embryonic kidney(HEK)-293 cells.Methods The 1 000 bp fragment was amplified by PCR with human genomic DNA as a template and was directionally cloned into pGL3-basic multiple cloning sites to construct the luciferase repor-ter plasmid pGL3-pIRF-3.Transfection of HEK-293 cells with the promoter-driven lucife-rase construct was performed to induce lucife-rase gene expression and calculate the relative luciferase activity unit(RLU).Promoter sequence of 1 000 bp upstream of transcription initiation site of IRF-3 was analyzed by using Promoter 2.0 Prediction software.Results DNA sequencing and restriction endonuclease analysis verified the successful construction of the plasmid pGL3-pIRF-3.This IRF-3 promoter exhibited a strong promoter activity with an increase of 42.2-fold of RLU in HEK-293 cells when compared with pGL-3 basic vector.The transfection experiment confirmed that the levels of its activation were significantly higher than that in controls in HEK-293 cells.Function analysis of IRF-3 promoter disclosed seve-ral GATA-1 and specific protein 1(Sp1) sites and E2F in minimal promoter region.Conclusion The plasmid pGL3-pIRF-3 promoter is successfully constructed and has a strong basal promoter activity in HEK-293 cells.

Objective To evaluate the therapeutic effect and safety of inhaling magnesium sulfate on infants with acute bronc-hiolitis. Methods Ninty infants with bronchiolitis were divided into 3 groups randomly and received either magnesium sulfate infusion inhalation or intravenous injection or normal saline inhalation respectively. The change of parameters of each group were observed and compared. Results Magnesium sulfate inhalation group and intravenous injection group were superior to control group in terms of the improvement of blood gas, clinical scores, continuous time of symptoms,signs, hospital days and clinical total efficiency(P

Objective To study the effect of sevoflurane pretreatment or aftertreatment on intrapulmonary shunt for patients with one lung ventilation(OLV)during thoracic surgical procedures .Methods 80 ASA I or II patients underwent thoracic surgery with OLV were randomly divided into four groups(n= 20 for each):(1)Propofol group(group P);(2)Sevoflurane pretreatment group(group S1);(3)Sevoflurane aftertreatment group(group S2);(3)Sevoflurane whole-treatment group(group S3) .Blood sam-ples were taken from radial artery and right atrial blood before induction of anesthesia(baseline T .0) ,before OLV(sevoflurane pre-treatment 30 min ,T1) ,after OLV 30 ,60 min and before the end of OLV(T2-T4)and after the end of OLV(T5)for measurement of blood gases and calculation of Qs/Qt .The indexs of hemodynamics and relative clinical data were recorded .Results Arterial oxy-gen pressure of the four groups for OLV significantly reduced ,when compared with double lung ventilation(P<0 .05) ,but there was no significant difference among the four groups(P>0 .05) .Intrapulmonary shunt of the four groups for OLV significantly in-creased ,when compared with double lung ventilation(P<0 .05) ,but intrapulmonary shunt of S1 ,S2 and S3 groups significantly de-creased ,when compared with P group ,and there was no significant difference for S1 ,S2 and S3 groups(P> 0 .05) .Conclusion Sevoflurane can decrease intrapulmonary shunt for patients during OLV ,but there is no significant difference for pretreatment or af-tertreatment or whole treatment and do not increase arterial oxygen pressure .

Objective To study the morphologic and pathological characteristics of cat scratch disease(CSD).Methods Eight cases with clinical data and tissue blocks were collected in Guangxi Zhuang Autonomous Region and Hainan Province.The tissues were successively stained by hematox- ylin and eosin,Warthin-Starry(W-S),acid fast and periodic acid-schiff(PAS)methods to study the histopathological changes and pathogens.Results W-S positive Bartonella henselae was the major pathogen of CSD and there was no acid-fast or PAS positive pathogen could be found in the tissues. There were three forms of histological representation as follows:plasmocytoid monocytes(PMO)and monocytoid B-cells(MBC)hyperplasia plus neutrophils immersion in lymphatic sinus(2 cases); MBC rich granuloma and micro-abscess formation(3 cases); starlit abscess with little or no bacteria in the granuloma(3 cases).Conclusions Bartonella henselae mainly transmits through cats.Contact histo- ry with cats and lymphadenectasis suggest the possibility of CSD.The diagnosis can be confirmed by the presence of W-S staining positive bacteria,MBC rich granuloma or micro-abscess and neutrophil reactions in histopathological exam.
