Objective To investigate the relationship between the detection of serological antibodies of Helicobacter pylori(HP) infection and the pathological features of gastric ulcer.Methods 228 cases of patients with gastric ulcer diagnosed by endoscopic biopsy(180 cases of benign ulcer and 48 cases of malignant ulcer) were enrolled in this study from January 2015 to October 2016.All subjects were given 14C-urea breath test.The positive rates of cytotoxin associated gene A(CagA),urease A(UreA),urease B(UreB),vacuolating toxin A(VacA) and flagellin antibodies in serum were determined by immunoblotting.The relationship between serum antibody level of Hp infection and pathologic features of gastric ulcer patients were analyzed.Results HP positive rate and type Ⅰ HP positive rate in malignant gastric ulcer group were significantly higher than those in benign gastric ulcer group(P<0.05).The positive rates of CagA,UreA,UreB,VacA and flagellin antibodies were significantly higher in patients with malignant gastric ulcer than those in benign gastric ulcer group(P<0.05).The positive rates of UreA,UreB,VacA and flagellin antibodies in patients with gastric ulcer area>2.0 cm2,severe mucosal inflammatory reaction and severe inflammatory reaction activity were higher(P<0.05).Conclusion The occurrence of gastric ulcer and progression of the disease could be related to the interaction of HP virulence factors.HP serological antibodies detection could help to classify patients with HP-positive gastric ulcer and formulate targeted prevention and treatment plan.

Objective To evaluate the value of dual-phase spiral CT scanning in diagnosis of small pancreatic carcinoma.Methods 21 cases with small pancreatic carcinoma (≤2 cm) underwent plain CT scan and dual-phase eahanced spiral CT including arterial phase(20~25 s after infusion)and pancreatic phase(50~60 s after infusion)with a 100 ml bolus injection of contrast material at 3~6 ml/s.CTattenuation values of tumor and normal pancreas in all scanning phase were obtained.Results The mean CT value of tumor was(42?14) HU(arterial phase)and (48?18) HU(pancreatic phase),the mean CT value of normal pancreas was (105?15) HU(arterial phase)and (86?11) HU(pancreatic phase).The dens difference of tumor-pancreas was significantly on arterial phase (69?15) HU.Conclusion The maximum dens difference of tumor-pancreas can be obtained on arterial phase CT scan,it has advantages in diagnosing pancreatic carcinoma of early period and to judge the resectionability of pancreatic carcinoma.

OBJECTIVETo explore the effects of different acupuncture depths of Lianquan (CV 23) for dysphagia after stroke.

METHODSTwo hundred and fifty-one patients with dysphagia after stroke were randomly divided into a deep acupuncture group (group A, 85 cases) a shallow acupuncture group (group B, 83 cases) and a glossopharyngeum acupuncture group (group C, 83 cases). Based on the conventional treatment, the glossopharyngeum acupuncture which was pricking without needles retained at lingual surface, posterior pharyngeal wall of the affected side, Jinjin (EX-HN 12) and Yuye (EX-HN 13) was used in the three groups. After the glossopharyngeum acupuncture, Lianquan (CV 23) was acupunctured 60-70 mm in the group A and 30-40 mm in the group B. The needles were all retained for 30 min. The treatment was applied once a day for 30 days in the three groups. Water swallowing test evaluation scale was observed before and after treatment, and the efficacy was assessed in the three groups.

RESULTSThe total effective rate was 95.3% (81/85) in the group A, which was better than 85.5% (71/83) in the group B and 83.1% (69/83) in the group C (both P < 0.05). The water swallowing test scores were decreased apparently in the three groups (all P < 0.01), and scores in the group A were the most obvious decline (P < 0.01). The decrease of scores in the group A was more remarkable than those in the group B and the group C after two weeks of treatment (both P < 0.05).

CONCLUSIONAcupuncture at Lianquan (CV 23) can effectively improve the dysphagia after stroke. The acupuncture depth can affect efficacy and the effect of deep acupuncture is better.

Objective To investigate the prevalence rate of healthcare-associated infection(HAI)in a hospital,so as to provide reference for making HAI control measures.Methods The cross-sectional survey on HAI was carried out among all hospitalized patients on May 26,2010,December 12,2012 and December 4,2013,respectively,sur-veyed data were analyzed.Results The prevalence rate was 6.66%(n =116),6.67%(n =113)and 6.33%(n =120)in 2010,2012 and 2013 respectively,and case rate was 7.29%(n=127),7.38%(n=125)and 6.97%(n=132) respectively,intensive care unit(ICU )had the highest infection rate,internal medicine ICU was up to 71 .43%. The main infection site was lower respiratory tract(44.53%),followed by surgical site infection (9.11 %)and uri-nary tract infection (9.11 %).The isolation rate of gram-negative bacteria,gram-positive bacteria and fungi was 60.81 %,20.38% and 18.81 % respectively.Usage rate of antimicrobial agents in three years was 32.95%, 29.87% and 25.59% respectively (χ2 = 13.16,P <0.01 ).Conclusion Prevalence rate of HAI in this hospital is high ,the main pathogen is gram-negative bacteria,the main infection site is lower respiratory tract ,antimicrobial use decreased year by year.Monitor on high risk departments,main sites and pathogens should be intensified.

The application of minimally invasive esophagectomy in the treatment of esophageal carcinoma has drawn much attention. At present, results of quite a number of clinical researches show that minimally invasive esophagectomy is helpful to reduce trauma and complications of esophageal surgery, especially cardiopulmonary complications with shorter length of hospital stay. However, there are still controversies on resection extent, lymph node dissection and survival as compared to traditional open esophagectomy. This paper discusses the minimally invasive esophagectomy on the telescopic esophagectomy of primary lesion, lymph node dissection and survival based on the worldwide reports of telescopic esophagectomy researches.

Objective To investigate the feasibility and safety of transcatheter closure of coronary artery fistula (CAF)with Amplatzer vascular PlugⅡ(AVPⅡ)in pediatric patients.Methods Between June 2012 and October 2015,5 children aged 0.9 to 7.0 years old and weighted 10 to 21 kg with CAF were admitted to the Department of Pediatric Cardiology in Shandong Provincial Hospital Affiliated to Shandong University.Aortic root angiography was used first to confirm the origin,shape,branches,drainage and the diameter of the orifice of CAF by deploying the pigtail catheter.The AVPⅡwas retrogradely deployed into targeted artery through guiding catheter and aortic angiography was performed before releasing the plug.Results All the 5 children underwent transcatheter closure by AVPⅡsuccessful-ly.Two cases were involved with right coronary -right ventricular fistula,1 case of left anterior descending coronary -right ventricular fistula (residual fistula after surgical repair),and 1 case of left circumflex coronary -left atrial fistula. Four children had a single fistula,and 1 case had double fistulas.The diameter of the orifice ranged from 2.00 to 5.96 mm,and the selected occluders from 8 to 14 mm.The ratio of diameter of occluder to fistula orifice ranged from 2.3 to 3.4.All the patients were followed up for 4 to 44 months.Two patients developed instant minor and modera-te aortic re-gurgitation.No other complications such as thrombosis,embolization,residual shunt,arrhythmia,coronary dissection or perforation occurred.Conclusions Transcatheter closure of CAF by AVPⅡin pediatric patients is feasible and safe. Aortic regurgitation should be noted,especially during the procedure.

Objective To investigate the association between the obstructive sleep apnea-hypopnea syndrome(OSAHS) in hypertension and insulin.Methods A total of 521 patients were divided into 4 groups according to apnea-hypopnea index and OSAHS degrees.The control group ( group Ⅰ ),mild OSAHS group ( group Ⅱ ),moderate OSAHS group ( group Ⅲ ) and severe OSAHS group ( group Ⅳ ) had 89 patients,194 patients,118 patients and 120 patients respectively.Results The BMI[( 30.4 ± 3.8 )kg/m2],apnea-hypopnea index ( AHI,3.8 ± 0.1 ),Fasting insulin (FIns)[(3.08 ± 0.26 ) mU/L]and insulin resistance ( 2.43 ± 0.27 ) of patients in severe OSAHS group were significantly higher than that of in the control,mild OSAHS group and moderate OSAHS group ( P ＜ 0.01 ).The levels of saturation of minimum oxygen from skin of patients in severe OSAHS group was significantly lower ( MSpO2 ) than in that of the control,mild OSAHS group and moderate OSAHS group.Multiple linear regression analysis showed that fasting plasma insulin and insulin resistance was positive correlation with apnea-hypopnea index,while they also negatively associated with saturation of minimum oxygen.Conclusions FIns and insulin resistance strongly associate with AHI and levels of saturation of minimum oxygen from skin.Hypertensive patients with OSAHS have more chances to suffer with insulin resistance.

Nowadays,transjugular intrahepatic portosystemic shunt (TIPS) has already become the main means for the treatment of portal hypertension and its complications due to cirrhosis.The Viatorr stent that is specifically designed for TIPS has been available in China since the end of 2015,but it has not been widely used in clinical practice in China so far.At present,superimposed release dual-stent technology by using one bare stent and one covered stent,as simulation of Viatorr stent,to perform TIPS is still employed in many clinical centers in China.Dual stent technology carries unique advantages,although the long-term efficacy of dual-stent implantation technology is not as good as that of single-stent implantation technology.This paper aims to make a comprehensive review about the dual-stent technology used for TIPS,focusing on the dual-stent technique classification and advantages,the causes and the managements of postoperative shunt dysfunction,etc.so as to let this technique can be mnore effectively used in treating portal hypertension caused by cirrhosis.
