Objective:To construct a health education program for patients with permanent enterostomy based on the information motivation behavioral skills model, and to test its effectiveness in improving patient readiness for discharge and reducing the incidence of early ostomy complications after discharge.Methods:From February 2021 to January 2022, convenience sampling was used to select 68 patients with low rectal cancer who were diagnosed by the Colorectal Surgery Department at the First Affiliated Hospital of Wenzhou Medical University and underwent abdominal perineal combined radical resection of rectal cancer (Miles) as research subjects. Randomized number series were generated using the digital table method, and the subjects were randomly divided into control group (33 cases) and intervention group (35 cases) using the envelope method. The control group was housed in the first ward, while the intervention group was housed in the second ward. The control group implemented the conventional health education, while the intervention group carried out the health education based on the information motivation behavioral skills model. The discharge readiness scores, ostomy self-efficacy and ostomy complications were compared between the two groups on the day of discharge and one month after discharge.Results:Patients in the intervention group had higher discharge readiness scores and higher discharge readiness levels than those in the control group, with statistical differences ( P<0.01) . The intervention group had higher levels of ostomy self-efficacy than the control group one month after discharge, with statistically significant difference ( P<0.01) . At the time of discharge for one month, the overall incidence of ostomy complications in the intervention group was 11.43% (4/35) , lower than 42.42% (14/33) in the control group, with a statistically significant difference ( P<0.01) . Conclusions:The health education program based on the information motivation behavioral skills model can effectively increase the readiness of patients with permanent enterostomy for discharge, reduce the incidence of complications of the ostomy and surrounding skin, improve the ostomy self-efficacy and promote patient rehabilitation.

Objective: To describe the dermoscopic features of extramammary Paget′s disease (EMPD) and chronic eczema of the vulva, and to explore the value of dermoscopy in the diagnosis and differential diagnosis of the above diseases. Methods: Dermoscopic images were collected from 20 patients with histopathologically confirmed vulvar EMPD and 16 patients with clinically confirmed chronic eczema of the vulva in Hospital for Skin Diseases, Chinese Academy of Medical Sciences and Pekin Union Medical College from January 2017 to April 2018, and retrospectively analyzed. Fisher′s exact test was used to compare the prevalence of dermoscopic features between the two groups. Results: As dermoscopy showed, the milky red background was observed in 19 EMPD patients and in only 1 patient with chronic eczema, and there was a significant difference in the prevalence of milky red background between the two groups (P < 0.001) . White scales were the most common desquamation, and were observed in 9 EMPD patients and 13 patients with chronic eczema (P = 0.128) . Blood vessels were uniformly distributed in EMPD patients, including dotted-globular vessels in 19 and linear vessels in 14, while blood vessels were distributed in a patchy or clustered pattern in the patients with chronic eczema, including dotted-globular vessels in 16 and linear vessels in 7. There was a significant difference in the prevalence of different distribution patterns of blood vessels between the two groups (P < 0.001) . Bright white streaks, bright white structureless area and reticular structure were observed in 19, 20 and 19 EMPD patients respectively, and in 1, 1 and 1 patient with chronic eczema respectively, and there were significant differences in the prevalence of the above 3 structures between the two diseases (all P < 0.001) . Conclusion Vulvar EMPD and chronic eczema both show characteristic dermoscopic features, and dermoscopy is of great value to the diagnosis and differential diagnosis of EMPD.

Objective To observe the effects of dual-task motor training on motor and balance function for stroke patients. Methods From January, 2016 to June, 2017, 30 patients with stroke were assigned randomly into control group (n = 15) and treatment group (n = 15). Both groups accepted routine physical therapy, the control group accepted anti-gravity treadmill training, while the treatment group accepted dual-task training with anti-gravity treadmill, for four weeks. They were measured with balance training and evaluation system, and assessed with Fugl-Meyer Assessment-lower extremity (FMA-L), Berg Balance Scale (BBS) and modified Barthel Index (MBI), before and after treatment. Results The range of swaying on X axial (Rx) and Y axial (Ry), as well as rectangle area (RecArea) decreased after treatment in the treatment group (t > 4.719, P < 0.001), while RecArea decreased in the control group (t = 5.069, P < 0.001). Ry and RecArea were less in the treatment group than in the control group (t > 2.288, P < 0.05). The scores of FMA-L, BBS and MBI improved after treatment in both groups (t > 7.316, P < 0.001), and improved more in the treatment group than in the control group (t > 2.322, P < 0.05). Conclusion The dual-task training via anti-gravity treadmill may improve motor and balance function in stroke patients, and promote the activities of daily living.

OBJECTIVEThe exact mechanisms of defect closure in patients with perimembranous ventricular septal defect (PMVSD) remain unknown. We hypothesized that the expression of urokinase type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) may mediate extracellular matrix (ECM) remodeling in aneurysms.

METHODSeven normal heart tricuspid septal leaflet and 33 aneurysms were collected in Shanghai Renji Hospital and Shanghai Children's Medical Center from January 2008 to June 2010. Immunohistochemical expression of uPA and PAI-1 in 4 normal heart valvular tissues and 15 aneurysms was detected with immunohistochemical methods. The expression of uPA and PAI-1 mRNA in 3 normal heart valvular tissues and 7 aneurysms was studied by real time fluorescent PCR; the protein expression of uPA and PAI-1 in 4 normal heart valvular tissues and 11 aneurysms was tested with Western blotting.

RESULTThe surface of the aneurysms were completely covered by endothelial cells. Two types of granulation tissue, myxoid and fibrous, were associated with the aneurismal formation. uPA were recognized predominantly in valvar interstitial cells (VICs) which located mainly in regions adjacent to the endothelium and smooth muscle cells of blood vessels. PAI-1 was found in both VICs which located mainly in granulation tissue and endothelial cells. Nine aneurysms expressed a higher uPA activity than 4 normal valvular tissues ((74.6±11.8)% vs. (49.5±7.4)%; t = 3.87, P = 0.003) and six aneurysms expressed a low uPA activity ((10.3±3.1)% vs. (49.5±7.4)%; t=11.78, P=0.000) and a high PAI-1 activity ((55.2±1.7)% vs. (50.8±3.8)%; t=2.55, P=0.034) using immunohistochemical methods. uPA / PAI-1 ratio of protein expression tested by Western blot was 0.88±0.22 in four normal heart vavular tissues; five aneurysms expressed high uPA activity and low PAI-1 activity and uPA/PAI-1 ratio was 4.26±2.04; while the other 6 cases expressed low uPA activity and high PAI-1 activity and uPA/PAI-1 ratio was 0.30±0.07; the difference among the three groups was statistically significant (P<0.05). The rate of uPA/PAI-1 in relative copy of mRNA expression among normal heart valvular tissue, high uPA expressed aneurysms and low uPA expressed aneurysms are also significantly different (2.14±0.17 vs. 0.45±0.04; 2.14±0.17 vs. 4.38±1.41, P<0.05) respectively.

CONCLUSIONThe expression of uPA and PAI-1 in VICs suggests that interactions among these molecules contribute to the aneurysm formation and development. This provides a potential mechanism for defect closure in patients with PMVSD.

Objective To investigate the clinical effect of botulinum toxin type A (BTX-A) injections guided by electromyography in combination with electrical stimulation in the treatment of upper limb spasticity poststroke.Methods Forty-five patients with upper limb spasticity following stroke were recruited.They received multiple intra-muscular BTX-A injections guided by electromyography and electrical stimulation.Rehabilitation training was administered after the BTX-A injections.The results were assessed using the modified Ashworth scale (MAS),the Fugl-Meyer upper limb assessment (FMA),active range of movement (AROM) and the modified Barthel index (MBI).All the assessments were performed at the baseline,and then 1 week,2 weeks,1 month,and 3 months after the injections.Results Compared with the baseline scores the MAS,FMA,AROM and MBI results had all obviously improved by 2 weeks after the BTX-A injections.Compared with 2 weeks after the injections,the FMA and AROM scores at 1 month were significantly higher and there were further significant improvements at 3 months.No patient demonstrated obvious side effects from the therapy.Conclusion BTX-A injection guided by electromyography and electrical stimulation is safe and has definite beneficial effects on upper limb spasticity after stroke.

Objective To investigate the risk factors of vagus nerve invasion of advanced adenocarcinoma of esophagogastric junction (AEG).Methods The specimens from 98 patients with advanced AEG who underwent radical total gastrectomy and esophagogastric Roux-en-Y anastomosis from January 2011 to August 2012 at the First Affiliated Hospital of Anhui Medical University were collected.Serial section cutting was done and the upper and bottom incisional edges of every section were marked.The specimens were stained by hematoxylin-eosin solution,S-100 and CK immunohistochemistry.Vagus nerve invasion could be affirmed if cancer cells were observed in the peripheral space of vagus nerve and vagus nerve parenchyma or cancer cells infiltrated along the peripheral space of vagus nerve.Relationship between nerve invasion and clinicopathological factors was analyzed using chi-square test or Fisher exact probability.Factors related to vagus nerve invasion were analyzed using one-way analysis of variance and multi-factor logistic regression analysis.Results The incidence of vagus nerve invasion was 28.6％ (28/98),and the tumor only invaded the vagus nerve which had the same altitude as the upper incisional edge.The results of one-way analysis of variance showed that Siewert classification,intravascular cancer emboli,lymph node metastasis,the degree of lymph node metastasis,clinical staging,the degree of tumor differentiation were correlated with the vagus nerve invasion (x2 =14.156,14.552,5.454,10.706,6.919,14.767,P ＜ 0.05).The results of multi-factor logistic regression analysis showed that Siewert classification,intravascular cancer emboli and degree of tumor differentiation were the independent influencing factors of vague nerve invasion (OR =3.667,10.368,0.249,P ＜ 0.05).Conclusion Vagus nerve invasion is correlated with Siewert classification,intravascular cancer emboli and degree of tumor differentiation.The range of vagus nerve invasion is restricted under the upper incisional edge of tumor section.

In the present experiment the high dose of LRH-A was injected into pregnant rats on Day 9 of pregnancy. Morphology and histochemistry of corpus luteum were studied. It was found that 24 hours after injection LRH-A could effectively cause the corpus luteum to degenarate. A great many large lipid droplets occured in the luteal cells, and the activity of 3?-HSD and of SDH of these cells decreased. At the same time the activity of AcP increased in a few of luteal cells. 48 hours after injection the effects outlined above became more distinct, and the activity of G-6-PD also began to decrease. The activity of 20 ?-HSD in both control and experimental groups was negative 24 hours after injection, while the activity of the AIP increased distinctly in endothelium of the capillary network of corpus luteum. These changes indicated that the high dose of LRH-A had damaged corpus luteum and reduced its synthetic and secretory function of progesterone which, we believe, plays a main role in terminating pregnancy.

Ten pregnant rats randomly chosen from the total twenty rats on day 9 ofprognancy were injected a high dosage of LRH-A.The other ten were used ascontrol group.After one day and two days the ultrastructure of the luteal cell wasobserved by transmission electron microscope.Compared with the control group,theexperimental group showed an increase of lipid droplets,and a lot of large lipiddroplets appeared.The smooth endoplasmic reticulum decreased,dissolved and lostits regular array.Mitochondria degenerated,Autophagocytic vacuole,lysosome,myelin figure,multivesicular body as well as residual body increased.Golgi appa-ratus swelled in the first day after injection,and then shrank.Microvilli on thesurface of the cell decreased.The above results all suggest that with the injection of high dosage of LRH-Ainto the pregnant rats,luteal cell shows morphologic regression and decrease insecretive function.
