Objective To assess the prevalence and related factors of gastroesophageal reflux disease (GERD) in troops stationed in southern China. Methods An investigation with validated questionnaire and stratified random sampling method was carried out in troops stationed in southern China to survey the prevalence of GERD and its related factors. According to the definition of reflux disease questionnaire (RDQ) score,the severity and frequency of the dominant symptoms of GERD,such as heartburn,acid regurgitation,food reflux and non-cardiogenic chest pain were scored. People with score equaled to and higher than 12 (Sc≥12) were assigned to patient group,and those with score lower than 12 (Sc0.05). Subjects in the patient group had a higher incidence of abdominal distension,belching,nausea,vomiting,abdominal pain compared with control group. A higher incidence of laryngitis,pharyngitis and ulcerative stomatitis (P

Objective To assess the prevalence of gastroesophageal reflux disease(GERD) in the population of Fujian province, and to analyze the risk factors in relation to the disease. Methods A survey on GERD symptoms and its related factors was carried out in the population of Fuzhou city in Fujian province using a stratified random sampling method. According to reflux disease questionnaire (RDQ) score, the subjects were divided to GERD group with Sc≥ 12 and control group with Sc＜ 12.The risk factors related to GERD were compared between two groups. Results A total of 1347residents were investigated. The prevalence of GERD was 8.76 %, and male to female ratio wasincreased in population above 40 years of age (P＜0.05). The incidence of GERD in subjects with different occupations was as follows: the businessmen [17.91%(12/67)], retirees [13.48%(12/89)]and soldiers [2.94%(2/68)]. Symptoms including abdominal distension, belching, nausea, vomiting,dyspepsia were common in GERD group compared to control group (P ＜ 0.01). Besides, the laryngitis, pharyngitis and mouth ulcer were common in GERD group compared to control group ( P＜0.05). The risk factors of GERD were eating greasy (OR= 1.589) and sweetmeat (OR= 2.413),overeating (OR = 2.053), constipation (OR = 1.650), acridity food (OR = 1.366 ), coffee (OR =1.295), strong tea (OR= 1.362). Conclusions The prevalence of GERD is high in the population of Fujian province, and many factors are closely related to reflux.

Objective:To investigate the clinical value of neck vascular ultrasound and homocysteine (Hcy) level in patients with cerebral infarction and carotid stenosis.
Methods: Our research included 2 groups. Cerebral infarction group, n=115 patient who were treated in our hospital from 2012-01 to 2013-12, and Control group, n=110 healthy subjects from physical check-up. Neck vascular ultrasound was conducted to classify the degree of carotid stenosis as ①no stenosis, ②mild degree, the stenosis rate≤29%, ③moderate degree, the stenosis rate at 30%~69%,③severe degree, the stenosis rate at 70%~99%,④complete occlusion. Carotid plaque formation and vascular intima-media thickness (IMT) were examined by neck ultrasound. Blood levels of Hcy and triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) were
measured in clinical laboratory.
Results: Compared with Control group, Cerebral infarction group had the higher rate of carotid stenosis 89.56%vs 10.91%, more plaque formation 73.91%vs 6.08%and increased IMT (1.85 ± 0.42) mm vs (0.75 ± 0.21) mm;higher blood levels of Hcy (42.32 ± 12.02) μmol/L vs (6.32 ± 2.45) μmol/L and higher rate of high blood Hcy syndrome 71.30%vs 3.63%;higher levels of TC (4.25 ± 1.12) mmol/L vs (1.63 ± 0.74) mmol/L and LDL-C (5.96 ± 1.36) mmol/L vs (2.32 ± 0.82) mmol/L, P<0.05. In Cerebral infarction group, the patients with complete carotid occlusion and severe stenosis had the higher rate of plaque formation and increased IMT;higher levels of Hcy and more high blood Hcy syndrome;higher levels of TG and LDL-C than the patients with mild and moderate carotid stenosis, P<0.05. Logistic analysis indicated that the levels of IMT, Hcy and LDL-C were the independent risk factors for cerebral infarction and carotid stenosis.
Conclusion: The patients with cerebral infarction and carotid stenosis have obviously increased blood level of Hcy. Hcy may predict various degree of carotid stenosis in relevant patients.

Objective To explore the correlation between serum uric acid levels and uric acid excretion indexes in children with primary nephrot?ic syndrome(PNS),and to reveal the prevalence of hyperuricemia and its possible causes in PNS. Methods The clinical data in 74 cases of pe?diatric PNS were retrospectively analyzed. These patients were grouped as hyperuric acid(HUA)or non?hyperuric acid(NUA),and their clinical features and laboratory findings were compared between two groups,including age,serum uric acid,serum creatinine,urea,cystatin C,triglycer?ide,cholesterol,albumin,creatinine clearance rate,24 hours urine uric acid,serum uric acid/serum creatinine,uric acid clearance,and the frac?tional excretion of uric acid and other indicators of differences. In addition ,a correlation analysis was carried out for the excretion of uric acid index. Results Several factors were lower in HUA group than that of NUA group ,such as the serum albumin and fractional excretion of uric acid(P1=0.034,P2=0.025);while the serum cystatin C and serum uric acid/serum creatinine ratio(P1=0.038,P2=0.001)was higher in HUA group. The uric acid excretion was negatively correlated with serum uric acid levels in all 74 children with PNS(r=-0.43,P=0.016),and the serum uric acid/creatinine ratio was positively correlated with serum uric acid(r=0.486,P=0.001). Conclusion Both the increase of blood uric acid production and excretion reduction were observed in children with PNS ,and the serum uric acid levels and renal tubular function is closely related.

Objective:To investigate the affects of NOD2 on rapamycin (Rap)induced autophagy and on the proliferation and mi-gration of tongue squamous carcinoma SCC-1 5 cells.Methods:① Synthesized NOD2 over-expression plasmid and NOD2-shRNA were transfected into SCC-1 5 cells respectively.②Normal control SCC-1 5 cells,NOD2 over-expression cells and NOD2-shRNA cells were treated with Rap to induce autophagy.Then,the expression of LC3 and Beclin-1 was examined by Western blot.Cell pro-liferation was tested by MTT assay.Cell migration was assessed by wound healing assay.Results:①After Rap treatment,the expres-sion of protein LC3-Ⅱand Beclin-1 in NOD2 over-expression cells increased(P <0.05)and in NOD2-shRNA cells were suppressed (P <0.05).② Compared with control group,the proliferation and migration ability were decreased in NOD2 over-expression cells (P <0.05),but in NOD2-shRNA cells the proliferation and migration ability were increased(P <0.05).Conclusion:NOD2 can up-regulate the autophagy and suppress the proliferation and migration of tongue squamous SCC-1 5 cells.

OBJECTIVE: To investigate the location, staging, clinical symptoms, imaging features, and surgical treatment of the congenital cholesteatoma of middle ear (CCME). METHOD: This was a retrospective review of 20 CCME cases. RESULT: Of 20 cases with CCME, 2 cases were classified as Postic stage I, 0 as stage II, 13 as stage III, 5 as stage IV. Conductive hearing loss was the most common clinical symptom. The mean preoperative PTA was 54.1 dB, and the mean ABG was 41.7 dB. One case underwent a modified mastoidectomy and a second-stage ossicular reconstruction; 2 cases experienced a radical mastoidectomy without ossicular reconsturction for extensive cholesteatoma; 5 cases underwent modified mastoidectomy and a one-stage tympanoplasty, with one case diagnosed as congenital malformation of ossicular chain (stapes hypoplasia); other 12 cases underwent a one-stage tympanoplasty. The cholesteatoma localized to the posterior-epitympanum or mesotympanum in all patients, mainly located in the incudostapedial joint. The mean postoperative PTA from 16 cases was 35.3 dB, and A-B gap was 20.2 dB. All patients were followed-up for at least 1 year after operation and recurrence was found in 2 cases. Three cases were accompanied with congenital malformation of ossicular chain. CONCLUSION CCME is a rare entity and diagnosis is usually delayed in clinical practice due to the silent nature of disease in its early stage. The prognosis of CCME mainly depended on the stage of the lesions.

Objective To establish the rabbit model with hepatic VX-2 tumor and to investigate the intake of folate-conjugated silica-coated gold nanorods (GNRs@SiO2-FA) in experimental rabbits. Methods Under CT-guidance, animal model with VX-2 liver cancer was established in 27 rabbits by using puncture inoculation method. CT scanning and sonography were employed to observe the tumor growth. After two weeks, the rabbits were randomly and equally divided into blank control group (n=9, injection of saline), portal vein injection group (n=9, injection of GNRs@SiO2-FA) and intra-tumoral injection group (n=9, injection of GNRs@SiO2-FA). Every three rabbits from each group were sacrificed each time at 24 h, 48 h and 72 h after the treatment. The tumor tissue and the major organs were collected and sent for pathological examination. The cellular uptake of GNRs@SiO2-FA was studied by confocal laser scanning microscopy. Results The rabbit model of VX-2 liver cancer was successfully established. CT and sonography examination indicated that the tumor was rich in blood supply. Confocal laser scanning microscopy revealed that GNRs@SiO2-FA could specifically bind with tumor cells within 24 hours after injection, then the GNRs@SiO2-FA entered into the tumor cells and gathered in the tumor cytoplasm. Conclusion GNRs@SiO2-FA has highly targeted effect on the liver cancer cells in experimental animals, which has very important application prospect in targeting hyperthermia therapy and in 125I seed implantation therapy.

Random amplified microsatellite polymorphism (RAMP) markers were used to access the genetic diversity among 112 samples of nine populations of Dendrobium officinale Kimura et Migo. Using 16 informative primers, 123 bands were amplified and 86 (69.92%) were polymorphic. The polymorphic bands from three to eight could be detected for each RAMP primer, with a mean of 5, indicating abundant genetic diversity among populations. Genetic similarity coefficients ranged from 0.250 to 0.813. UPGMA dendrogram illustrated 9 populations clustered into 3 groups, and the cluster pattern showed correlation with the locations of the D. officinale populations. These results were supported by the previous conclusions that were achieved by other molecular markers, and RAMP is proved to be effective for evaluating the genetic diversity of wild populations of Dendrobium officinale.

Objective To evaluate the strategies and effect of surgical treatment for concomitant abdominal aortic aneurysm (AAA) and colorectal cancer (CRC). Methods Literatures on concomitant AAA and CRC published from January 1988 to December 2008 were retrieved from Pubmed, Sciencedirect, Ovid, CBMdisc, CNKI and et al, and correlated indexes were extracted for analysis. Differences among the groups were analyzed using the t test, chi-square test and fisher's exact test. Results A total of 367 cases of concomitant AAA and CRC treated by operation were retrieved. The length of operation delay of patients who received radical resection of CRC first was (115 ± 21 )days, which was significantly longer than (42 ± 8 )days of patients who received open abdominal aortic aneurysm repair (OAAR) first (t = 18. 9, P <0.05). The 30-day complication rate and accumulative length of hospital stay of patients who received one-stage radical resection of CRC + OAAR were 10.5% ( 12/114 )and (23 ±6) days, and 26.0% (47/181) and ( 16 ±4)days of patients who received two-stage radical resection of CRC + OAAR, with a significant difference ( χ2 = 10.42, t = 12. 01, P <0.05 ). The accumulative length of hospital stay of patients who received radical resection of CRC + endovascular aneurysm repair (EVAR) was (12 ±4) days, which was significantly shorter than that of patients who received radical resection of CRC + OAAR [ ( 19 ±5 ) days ] ( t = 9.48, P < 0. 05 ). The 4-year survival rate of patients who received two-stage radical resection of CRC + OAAR was 43.5% (27/62), which was significantly lower than that of patients who received two-stage radical resection of CRC + EVAR [69.2% (18/26) ] or one-stage radical resection of CRC + OAAR [73.7%(14/19) ] (χ2 =4.83, 5.28, P<0.05). Conclusions If the diameter of AAA is under 5 cm, radical resection of CRC should be firstly carried out; but if the diameter of AAA is above 5 cm, OAAR should be firstly carried out to prevent the rapture of tumors. One-stage surgery is better than two-stage surgery if patients could tolerate it.

Objective To screen differentially expressed serum proteins by label-free quantitative proteomics in patients with atopic dermatitis,in order to discover serum protein markers for atopic dermatitis.Methods Serum samples were collected from 6 patients with atopic dermatitis and 6 healthy human controls.Then,the samples from the patients were pooled together,so with those from the controls.Proteins were extracted from the two joint serum samples followed by separation with one-dimensional sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE).Peptides were obtained by enzymolysis in protein gels,which were subsequently identified by high performance liquid chromatography tandem mass spectrometry.The Mascot software was used for database searching,and the Scaffold software for relatively quantitative analysis of proteins.Results Totally,76 proteins with a difference of greater than 1.5 folds were identified between the serum samples of patients with atopic dermatitis and controls.There were 50 up-regulated and 26 down-regulated serum proteins in the patients compared with the healthy controls.Among these differentially expressed proteins,26 were only detected in the sera of the patients,and 14 proteins in those of the controls.Conlusion Differences exist in the expression of serum proteins between atopic dermatitis patients and healthy people.
