Objective Endoscopy, 24-hour esophageal pH monitoring were used to objectively estimate the extent of gastroesophageal reflux and affecting factor after esophagectomy for cancer. Methods Endoscopy, 24 hour pH monitoring were performed in thirty-nine patients, including 21 undergoing esophagogastrostomy above the aortic arch (group A) and 18 below the aortic arch (group B). Results (1) DeMeeter score of gastroesophageal reflux in group A was significantly higher than that in group B in different postoperative period (P0.05). Conclusion Thoracic anastomosis in the lower thorax is more likely to be followed by gastroesophageal reflux and esophagitis. There is no significant change in extent of gastroesophageal reflux over time.

Objective To investigate the dynamic change of serum high sensitive C-reactive protein (hsCRP) after carotid artery stenting (CAS) and its correlation with in-stent restenosis.Methods The serum hsCRP levels were determined before procedure,at 12 hours,7 days,3 and 6 months after procedure in patients who underwent CAS in the Department of Neurology,Jinling Hospital,Nanjing Their cerebral angiography was reexamined and whether there was in-stent restenosis after 6 months was observed.Results Eighty-four patients treated with CAS were included in the study.Fifteen (24％) had in-stent restenosis after CAS.The stenosis in 3 of them was ＞ 50％,and the stenosis m 12 of them was 30％ to 50％.The serum hs-CRP levels in all patients after procedure were significantly higher than those before treatment (all P ＜ 0.01 ),and they were significantly lower at 6 months after procedure than before treatment (all P ＜0.01).Univariate analysis showed that the proportion of diabetes in the restenosis group was significantly higher than that in the non-restenosis group (P＜0.01).At 7 days (8.83 ± 1.94 mg/L vs.6.77 ± 1.63 mg/L,t =14.398,P=0.044),3 months after procedure (8.26 ± 1.32 mg/L vs.4.58 ± 1.45 mg/L,t =17.569,P =0.008) and 6 months after procedure (7.04 ± i.07 mg/L vs.3.12 ± 1.28 mg/L,t =21.867,P =0.003),the serum hs-CRP levels in the restenosis group were significantly higher than those in the non-restenosis group,and the difference of the serum hs-CRP level (△ hs-CRP) before procedure and at 6 month after procedure was significantly lower than that in the nonrestenosis group (0.85 ± 0.13 mg/L vs.4.89 ± 0.94 mg/L,t =16.987,P =0.000).Multivariate logistic regression analysis showed that /hs-CRP (odds ratio [ OR] 2.392,95％ confidence interval [ CI] 1.538 -3.513; P =0.009) and diabetes (OR 1.840,95％ CI 1.372 -2.241; P =0.023) were the risk factors for instent restenosis.Conclusions The serum hs-CRP level increased significantly at 12 hours after CAS procedure,and then decreased continuously.At 6 months after procedure,the more decrease of the serum hs-CRP level,the lower risk of occurring in-stent restenosis was.

Objective To observe the acarbose combined therapy with sugar pulse phase Ⅰ and phase Ⅱ clinical curative effect of diabetic nephropathy and the effects of oxidative stress on the patients.Methods 188 cases of phase Ⅰ and phase Ⅱ DN patients were selected in hangzhou xixi hospital endocrinology from January 2012 to December 2012,randomly divided into control group and treatment group,94 cases in each groups,the control group given conventional western medicine treatment of diabetic nephropathy,antihypertensive agents using lotensin.Treatment group was treated in the control group on the basis of taking acarbose and sugar pulse tablet.The control group and treatment group a course of eight weeks.Testing for 48 hours patients before and after the urine trace albumin in the urine(UAER)and creatinine ratio(ACR)with urine trace albumin,serum oxide dismutase(SOD),catalase(CAT)and malondialdehyde(MDA).Results The total effective rate was 91.5％in the treatment group,which was significantly higher than that in the control group(68.1％),the total effective rate of the two groups was statistically significant(P<0.05); The levels of UAER and ACR in the treatment group were lower than those in the control group(P<0.05); After treatment,the levels of serum SOD and CAT in the treatment group were higher than those in the control group,the MDA level was lower than that in the control group,the difference was statistically significant(P<0.05); No adverse reactions occurred in the two groups.Conclusion Acarbose combined with Tangmaikang granules in the treatment of DN patients with significant effect,can improve the treatment of diabetic nephropathy,the levels of oxidative stress injury is related to diabetic nephropathy mechanism.

Objective To investigate the change of gastroesophageal reflux including acid reflux,duodenogastroesophageal reflux (DGER) and its effect on expression of COX-2 and TNF-α in the remnant esophagus in different period after esophagectomy for cancer.Methods Thirty-two patients who underwent esophagectomy for cancer were selected randomly.Twentyfour-hour pH and spectrometric bilirubin monitoring,endoscopy were periodically performed.Esophageal mucosa samples were obtained by endoscopic biopsy.Expression of COX-2 and TNF-α within remnant esophageal mucosa was detected using immunohistochemical assay.Results ( 1 ) The incidence of reflux esophagitis and extent of acid reflux gradually increased over time after surgery for cancer ( P ＜ 0.05 ).(2) Very low level of COX-2 and TNF-α expression was detected in normal esophageal squamous mucosa.The expression of COX-2 and TNF-α was observed in cytoplasm of basal cell of esophageal epithelium after esophagectomy for cancer.High intensity of COX-2 and TNF-α expression was detected in the metaplastic columnar mucosa.The level of TNF-α expression in the remnant esophagus where reflux esophagitis occurred was higher than that in the normal remnant esophagus ( P =0.0274 ).There was no significant difference in level of COX-2 expression in the remnant esophagus between reflux esophagitis occurred and not ( P =0.7403 ).Conclusion ( 1 ) The extent of acid reflux and incidence of esophagitis gradually increases over time.(2) The expression of COX-2 and TNF-α may represent an early change associated with gastroesophageal reflux.The expression of COX-2 may serve as a molecular marker of gastroesophageal reflux occurred.( 3 ) The durative expression TNF-α is likely involved with the pathogenesis of chronic reflux esophagitis.

Objective To evaluate the prognostic value of hyperintense vessel (HV) in patients with acute middle cerebral artery (MCA) occlusion.Methods Seventy-four consecutive patients with first ever stroke(48 male and 26 female,the mean age was (60.7 ± 15.3) years) in the territory of MCA,retrieved from Nanjing Stroke Registry Program between May 2009 and February 2011,were enrolled assubjects.All subjects completed brain MRI,and MRA or DSA indicated proximal MCA occlusion.According to the location and extent of HV,all subjects were classified into 3 groups:without HV,proximal HV and distal HV.Clinical data were obtained and compared among patients with different grades of HV.Logistic regression analysis was employed to confirm the relevant factors of prognosis 90 days after index stroke.Results HV was observed in 49 (66.2％ ) of the 74 enrolled patients.Among patients with HV,7 (9.4％ ) were classified as proximal HV and 42 ( 56.8％ ) as distal HV.Initial NIHSS score ( 11 ( 1 -22) ),10-day NIHSS score ( 13.5(4-25) ),infarction size ( ＞2/3:5 cases(6.8％ ) ),and 90-day mRSscore (3-6 scores:12 cases( 16.2％ )) were significantly lower in patients with distal HV than those without (15(6-25),Z=-3.544;7(0-22),Z=-4.461;20 cases(27.0％),x2 =20.916;27 cases (36.5％),x2 =22.689;all P＜0.01).The NIHSS score decreased from baseline to that on 10 days and the mRS score decreased from 10 days to that on 90 days in patients with distal HV was more than that in patients without distal HV. Multivariate analysis revealed that patients with older age ( OR =1.111,95％ CI 1.036-1.191,P=0.003),high infarction size (OR=3.679,95％ CI 1.35-10.025,P=0.011) worsened outcome,whereas distal HV (P =0.012,OR =0.131,95％ CI 0.027-0.638)improved outcome.Conclusion Distal HV on FLAIR may predict a favorable outcome in patients with acute middle cerebral artery occlusion.

Objective To investigate the correlation of the lesion pattern of internal border zone infarction (IBZI) with atherosclerosis and outcome.Methods Eighty-one patients with IBZI were retrospectively divided into a simple IBZI group and a mixed IBZI group (combined with other infarct patterns) according to diffusion-weighted imaging (DWI).The clinical characteristics were compared between the 2 groups.And then,the mixed IBZI group was further divided into 3 subgroups:IBZI + pial infarct (PI),IBZI + perforating artery infarct (PAI),and IBZI + PI + PAI.They were compared with the simple IBZI group respectively.Results There were no significant differences in the dinical characteristics,such as age,hypertension,and the numbers of patients with stent implantation between the simple IBZI group and the mixed IBZI group.The proportions of severe stenosis and occlusion of internal carotid artery (ICA) and/or middle cerebral artery (MCA) (P =0.009) and MCA lesions (P =0.032) in the mixed IBZI group were significantly higher.Among the patients with MCA lesions,the severe stenosis in the simple IBZI group was significantly more than that in the mixed IBZI group (P =0.042),while the occlusive lesions in the mixed IBZI group were significantly more than those in the simple IBZI group (P =0.022).The short-term (within 7 days) exacerbation (P =0.039) and poor outcome at 90 days (modified Rankin Scale＞ 3) in the mixed IBZI group (P=0.030) were significantly higher than those in the simple IBZI group.The subgroup analysis showed that the proportions of the short-term exacerbation (P =0.001 ) and poor outcome in patients at 90 days (P =0.010) in the IBZI + PI +PAI subgroup were significantly higher than those in the simple IBZI group.Conclusions The IBZI patients combined with other infarct patterns often exist severe cerebrovascular stenosis and occlusion,and their clinical outcome was poorer.For patients with MCA lesions,the mixed IBZI occurred more in patients with MCA occlusion,and the simple IBZI occurred more in patients with severe MCA stenosis.

Objective To investigate the inhibitory effect of matrine on inflammation by regulating Th1/Th2 bal-ance in asthmatic rats and the underlying mechanism related to SOCS3.Methods Ovalbumin-sensitized rats were established as asthma model, Animals randomly divided into four groups, as follows: control ( without any treatment) , model group, treatment group A ( low-dose matrine treated asthma rats ) and treatment group B ( high-dose matrine treated asthma rats) .The eosinophil counting, goblet cells percentage, inflammatory cell in-filtration in rat lung were analyzed and scored by morphological examination .IL-4 and IFN-γlevel in BALF were determined by ELISA and IFN-γ/IL-4 ratio was further calculated.Furthermore, the expression of SOCS3 in mRNA and protein level were detected by qRT-PCR and Western blot, respectively.Results Eosinophil count and percentage, goblet cell percentage and inflammatory cell infiltration score were significantly lower than that in treatment group A and B as compare to model group ( P<0.05 ) .The group A exhibited a lower IFN-γlevel and a higher IL-4 level ( P<0.05 ) .IFN-γlevel in treatment group A and B were higher while IL-4 level were lower as compare to model group.Meanwhile, SOCS3 mRNA level in rat lung tissue was elevated in model group.Ma-trine treatment decreased SOCS3 expression in group A and B .Similar trend was found in SOCS3 protein level. Conclusions Matrine may exhibit antiinflammatory effect by inhibiting SOCS3 expression and correcting Th1/Th2 balance in asthmatic rats.

OBJECTIVETo study a group of patients with abnormalities of esophageal motility in manometric investigation.

METHODSFrom 1990 to 1999, 14 patients with dysphagia (9), chest pain (3), or both (2) were studied. All patients denied symptoms of heartburn, regurgitation, odynophagia, epigastric discomfort, and investigation failed to show any evidence of ischemic heart disease. A perfused catheter with 4 separate lumens was used and connected to output transducers (Medtronic, PC Polygraf HR).

RESULTSOf the 14 patients, 11 had motor disorders of the esophageal body including simultaneous contractions without normal peristalsis (5), alternative occurrence of simultaneous contractions and normal peristalsis (3), aperistalsis (2) and very low amplitude peristalsis (1). Seven patients were diagnosed with motility disorders of the lower esophageal sphincter including incomplete relaxation or no relaxation on swallowing (6), short relaxation duration (1). Four patients had more than one abnormal manometric findings.

CONCLUSIONSNon-specific esophageal motility disorder is not a real diagnostic entity, but only a group of manometric abnormalities. The relationship between the symptoms of the patients and the manometric findings was analysed. It is uncertain that these disorders have a common etiology. The revision of these abnormalities is difficult because the pathogenesis is unknown.
