Objective To investigate the relationship between gastroesophageal flap valve (GEFV) and reflux esophagitis(RE).Methods We analyzed 239 cases of RE diagnosed by endoscopy in our hospital from January 2007 to December 2009.RE was classified by Los Angeles classification system and GEFV by Hill system.The association of GEFV with RE was analyzed.Results The overall incidence of abnormal GEFV was32.9% (316/960) and that of RE was 24.9% (239/960).The incidence of severe RE ( grade C and D) in abnormal GEFV group was significantly higher than that in normal GEFV group (23.1% vs.2.4% , P = 0.000).RE grades were positively correlated with GEFV grades (r = 0.308, P = 0.000 ).The incidence of abnormal GEFV in RE patients was higher than that in non-RE (65.3% vs.22.2% ,P = 0.00 ).In terms of gender, there were more males than females in both RE group (63.6% vs.36.4% ) and abnormal GEFV group (60.1% vs.39.9% ).Additionally, incidence of RE increased with age, i.e.positively correlated with age (r=0.214,P =0.000).The incidence of abnormal GEFV also increased significantly in those over 30 years old, i.e.positively correlated ( r = 0.129, P = 0.000).Conclusion There is correlation between GEFV abnormality and RE.GEFV provides useful information for assessment and prediction of the reflux status of the patients.

Objective: To study correlation among serum levels of lipoprotein a[Lp(a)], uric acid (UA) and cardiac function in patients with acute myocardial infarction (AMI) complicated diabetes mellitus (DM).Methods: A total of 70 AMI+DM patients were enrolled as AMI+DM group, 60 pure AMI patients were enrolled as pure AMI group, 60 pure DM patients were enrolled as pure DM group, and 60 healthy people were selected as healthy control group.According to NYHA cardiac function class, AMI+DM patients were divided into class I~II group (n=58) and class III~IV group (n=12);according to their prognosis, they were divided into no cardiovascular event group (n=54) and cardiovascular event group (n=16).Serum Lp(a) and UA levels were measured in all group, and their correlation were analyzed.Results: Serum Lp(a) and UA levels of AMI+DM group were significantly higher than those of healthy control group, pure AMI group and pure DM group, and those of pure AMI group and pure DM group were significantly higher than those of healthy control group, P<0.01 all;Pearson compared with class I~II group, there were significant rise in serum levels of Lp(a)[(183.28±19.96) mg/L vs.(335.65±22.71) mg/L]、UA[(287.45±21.82) μmol/L vs.(437.79±26.72) μmol/L]in class III~IV group (P<0.01 both);compared with no cardiovascular event group, there were significant rise in serum levels of Lp(a)[(220.75±25.72) mg/L vs.(423.97±30.81) mg/L]and UA[(308.49±21.82) μmol/L vs.(442.97±29.75)μmol/L]in cardiovascular event group, P<0.01 both;Pearson correlation analysis indicated that serum Lp(a), UA levels were significant positively correlated with cardiac function class (r=0.410, 0.412, P<0.05 both), and serum Lp(a) level was significant positively correlated with UA level (r=0.496, P=0.023) in AMI+DM patients.Conclusion: Serum Lp(a), UA levels are closely correlated with cardiac function in AMI+DM patients, which can be used as indexes diagnosing and monitoring disease progress.

To increase the identification of pharyngeal bursa invasive fungal disease with lower cranial nerve involvement, reduce the misdiagnosis and improve the awareness of invasive fungal disease. We report the clinical data of a case with lower cranial nerve involvement as the first manifestation and reviewed the related literature.

Objective: To study the effects of mechanical strain on the proliferation of human osteoblasts. Methods: Cloned MG 63 human osteoblasts were cultured and seeded at 10 5/well in 6 well Bioflex cell cuture plates. Subsequently, the cells were exposed to mechanical strain stimulation (at 6%, 12% and 24% elongation rate respectively) for 24 hours using Flexercell 3000 Cell Stretching Unit. MTT colorimetric method was used to assess the proliferation of the cells. Results: The proliferation of MG 63 cells was significantly increased 24 h after mechanical strain treatment( P

Platelet activating factor(PAF), a potent phospholipid mediator of inflammation, has diverse physiological actions and participates in many diseases in vivo . In recent years, it has been revealed that PAF system involve in the expression of keratinocytes function and reaction of skin inflammation. Therefore, PAF system was found closely associated with inflammatory skin disease. Keratinocytes could express functional PAF receptors (PAF R) and involve in the action of epidermis cytokine system. The interaction between PAF system and other inflammatory mediators can lead to skin inflammatory cascade.

Objective To study the genes of a carbapenem-resistant Klebsiella pneumoniae strain isolated from a patient. Methods The antibiotic sensitivity test of a multidrug-resistant Klebsiella pneumoniae strain was done according to K-B and MIC method. Metallo-β-lactamase was detected by Modified Hodge Test and EDTA-disk synergy test. Both nine genes encoding β-lactamases, including blaKPC, blaIMP , blaVIM , blaSME , blaCTX-M , blaSHV, blaDHA , blaACT, Class Ⅰ integrase and Class Ⅰ integron were detected by PCR. Positive products were sequenced. Results The Klebsiella pneumoniae was resistant to carbapenems, cephalosporins, cefoxitin, ampicillin and trimethoprim/sulfamethoxazole. Only susceptible to aztreonam, gentamicin, tobramycin, amikacin, ciprofloxacin and levofloxacin. The blaIMP-1 and Class Ⅰ integron were positive. The blaIMP gene was identified by PCR and DNA sequencing confirmed that the gene belong to IMP-1 type Metallo-β-lactamase gene. The strain also carried Class Ⅰ integron and IMP-1 was located in Class Ⅰ integron 5'. Conclusions It is the first detection of IMP-1 Metallo-β-lactamase in Klebsiella pneumoniae. The production of IMP-1 carbapenemase is the main mechanism of carbapenem-resistant in Klebsiella pneumoniae, and multidrug resistance is related to ClassⅠ integron.

Although hemopoietic stem cell transplant have been used in treating malignant diseases of hematological system using high-dose chemotherapy and radiotherapy before transplant or non-transplant is very important. When the dose of chemotherapy and radiotherapy exceeds the ability the tissues can bear, normal tissue can be badly damaged, which limits the therapeutic efficacy of chemotherapy and radiotherapy. Treatments of hematological malignancies are expected to achieve the best therapeutic efficacy and the least damage of normal cells and tissues. Amifostine is an inorganic thiophosphate eytoprotective agent,its chemname is S-2(3-aminopropyl) amino dihydrogen phosphate.h is a prodrug whose active constitutent is free thiol,it can clears free radicals produced from cytotoxic drugs and radiotherapy in tissues exposed to them. It is a broad-spectrum cytoprotective agent which can protect multifarious normal tissues against damage of chemotherapy and radiotherapy. Using amifostine in proconditioning of hemopoietic stem cell transplant can lessen hematological and renal toxicity, it can also lessen renal toxicity produced by chemotherapeutics as platinum,cyclophosphamide and vincristine. The main purpose of this review is to discuss the cytoprotection of amifostine in hematological malignancies.

Objective:To determine blood magnesium and urinary magnesium in children with asthma exacerbation and discuss the relationship between the magnesium level and children with asthma attack. Methods:The observation group include 90 children who were 0~6 years old with asthma exacerbation that admission to our hospital since May 2008 to May 2012. The control group was 100 children with the same age to the observation group to accept the health examination. Every child in two groups were taking venous blood of 2ml and 24h urine samples. Record the amount of urine at the same time. Using automatic biochemical analyzer to detect the serum magnesium concentration and urinary magnesium concentration. Results: The urinary magnesium concentration of observation group was obviously lower than control group (t=8.52, P<0.001);the serum magnesium concentration of two groups had no significant difference (t=2.21, P>0.05). Conclusion:Children with asthma in acute attack stage with magnesium deficiency. Urinary magnesium concentration determination is simple, and it is a effective method that can be used to judge whether there is magnesium deficiency. Serum magnesium concentration cannot be used as a reliable indicator of magnesium ion balance.
