Objective To investigate the clinicopathologic features of gastrointestinal neuroendocrine carcinomas. MethodsThe diagnosis and treatment results of 45 cases were studied, and clinicopathologic features and immunohistochemical expressions of NSE, Syn and CgA were detected.ResultsMicroscopically carcinomas were divided into three types: type Ⅰ(25 cases), type Ⅱ(10 cases) and type Ⅲ(10 cases). The histologic categories were correlated with lymph node metastasis significantly( P0.05). The 5-year survival rate for type Ⅰ, type Ⅱ and type Ⅲ was 70%, 65% and 52%, respectively.ConclusionsThe combination of NSE, Syn and CgA immunohistochemical stainnig is necessary for the diagnosis of gastrointestinal neuroendocrine carcinomas. The histologic classification is coincident with the requirement of clinical treatment and prognosis.

Objective To study the effect of mental intervention on patients with postsurgical gastroparesis syndrome (PGS). Methods 70 patients with gastroptroparesis syndrome after abdominal operation were divided into the control group and the experimental group with 35 patients in each group according to chronological order.The patients in the control group accepted routine care,and the experimental group was given mental intervention based on routine care.Center for Epidemiological Survey Depression Scale (CESD) was used to evaluated the emotional state before and after intervention.Besides,the recovery of gastrointestinal function was appraised. Results The improvement level of anxiety in the experimental group was higher than the control group.The extinction time of symptoms,indwelling time of gastric tube,recovery time of food intake were shorter than the control group.Drainage time when gastric juice ＞ 800ml/d was shorter,recovery time of PGS and hospitalization time were shorter,the treatment cost was reduced,compared with the control group. Conclusions Mental intervention can alleviate the negative emotion and shorten the recovery time of patients with postsurgical gastroparesis syndrome.

Objective The purpose of this study was to assess the value of serial sectioning and immunohistoehemistry(IHC)for the diagnosis of senfinel lymph node(SLNs)metastases in patients with breast cancer,and to evaluate the significance of mierometastases and isolated tunlor cells(ITCs)in the SLNs. Methods Eighty pailents with clinically node-negative breast cancer underwent SLN biopsy with both99mTc-labeled sulfur colloid and iBosulfan blue dye for SLN identification.All SLNS and non-SLNs were evalnated with standard H&E stain and IHC analysis. Results SLNs were successfully identified in 78 of 80 patients(97.5%),the isotope/blue dye concordanee rate was 76.5%for all SLNs.Thirty two patients (41%)had histologically positive SLNs,and 13(40.6%)of these patients hod SLNS with micrometastatic disease.In 14(43.8%)of these patients,the SLNs were the only nodes involved.The sensitivity,specificity and accuracy of SLN biopsy in predicting axillary node stams were 96.9%,100%and 98.7%,reslaeetively.Patients with positive SLNs metastasis had a markedly higher proportion of non-SLNs metastases compared with those with only micrometastasis in the SLNS(78.9% vs 23.1%). Conclusions Serial sectioning and IHC ale sensitive methods for detecting breast cancer metastases in SLNS.The incidence of non-SLNs metastases is rather low in patients with SLNs that contain only micrometsstatic foci and ITCs.The prognostic significance and effect on surgical management of these occult disease have yet to be determined.

OBJECTIVETo investigate the vascular supply of intrinsic muscles of foot and anatomic basis for muscular flap design.

METHODSA radiopaque injectate (lead oxide-gelatin mixtures, 26 ml/kg) was injected into 10 fresh cadavers. The dissected regions were photographed and each intrinsic muscles on the foot was removed and radiographed. The number, type, diameter of vascular branches of muscles and their distributions were observed. The area of the vascular territory supplied by each source vessel was calculated using Scion Image for Windows software.

RESULTSThere were significant architectural differences among the intrinsic muscles. The muscles length varied from 22.5mm to 116.2mm [average, (66.1 +/- 23.2)mm]. The measured fiber length were relatively consistent, ranging from 14.2 mm to 27.5 mm [average, (20.2 +/- 4.5)mm]. There are 63 vascular branches into the 23 foot muscles, each muscle having average branches of 3.2 +/- 0.8. The average diameter of branches, the length and width of each vascular territorial area is (0.8 +/- 0.3) mm, (2.2 +/- 0.8) cm, and (0.9 +/- 0.4) cm, respectively. Other findings included that some muscles were not present in some cadavers.

CONCLUSIONSThe blood supply of intrinsic muscles of foot is abundant with different diameter and distributions of branches. There is an anatomic basis for muscular or musculoosseous flap design. There are 7 intrinsic muscles with large and reliable vascular supply which can be chosen as muscular flaps.

Objective:To investigate the diagnostic value of postsystolic shortening (PSS) and early systolic lengthening (ESL) on myocardial microvascular dysfunction in patients with ST-segment elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI).Methods:A total of 83 patients with STEMI who received emergency PCI in Renmin Hospital of Wuhan University from June to October 2021 were retrospectively collected. All patiets underwent two-dimensional echocardiography and myocardial contrast echocardiography (MCE) within 7 days after PCI. The patients were divided into global normal perfusion group and poor perfusion group according to global myocardial perfusion score index (MPSI). Left ventricular myocardium was divided into left anterior descending branch (LAD), left circumflex branch (LCx) and right coronary artery (RCA) regions, which were divided into regional normal perfusion group and poor perfusion group based on whether there were segments with microvascular dysfunction. Left ventricular end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) were measured by modified biplane Simpson method. Tomtec software was used to obtain conventional echocardiographic parameters, global longitudinal strain (GLS), as well as PSS and ESL parameters including postsystolic index (PSI), duration of postsystolic shortening (PSSduration), early systolic index (ESI) and duration of early systolic lengthening (ESLduration). Differences of parameters of global normal and poor perfusion groups, as well as regional normal and poor perfusion groups were compared. ROC curve was used to analyze the diagnostic value of PSS and ESL parameters and GLS in myocardial regions with microvascular dysfunction.Results:Significant differences were observed in LVEF, LVESV, GLS, PSI, ESI and PSSduration between global poor perfusion group and global normal perfusion group (all P<0.05). Compared with regional normal perfusion group, PSI, ESI and ESLduration of LAD and LCx regions, as well as PSI of RCA region in regional poor perfusion group were increased (all P<0.05). For GLS in different myocardial regions, LAD-GLS was the only parameter that decreased in regional poor perfusion group compared to regional normal perfusion group ( P<0.05). ROC curve analysis showed LAD-PSI, LAD-GLS, LCx-PSI, LCx-ESLduration and RCA-PSI were valuable parameters for diagnosis of myocardial microvascular dysfunction in different regions, among which LAD-PSI had the highest area under curve (AUC=0.809). Conclusions:PSS and ESL parameters are helpful for early diagnosis of myocardial microvascular dysfunction in STEMI patients after PCI, and can provide regional myocardial perfusion information according to the blood supply of different coronary arteries.
