Objective To explore the application of video-assisted thoracic surgery (VATS) in the diagnosis and treatment of mediastinal tumors. Methods Thirty-four patients with mediastinal tumors underwent VATS from June 1995 to December 2002. The patients comprised 9 men and 25 women, with a mean age 43 9 years (16～74 years). Entered into the study there were 14 cases of thymoma (9 benign thymomas and 5 malignant), 6 cases of neurogenic benign tumors, 5 bronchogenic cysts, 4 teratomas, 2 pericardial cysts and 3 other conditions (metastatic carcinoma, lymphoma and hemangioma racemosum, respectively). Maximum diameter of the tumors ranged 3 5 cm to 6 cm, mean 4 5 cm. Operations were performed under general anesthesia, double lumen endotracheal tube placement and single lung ventilation. The patients were maintained in the lateral decubitus position. Camera port was placed at the sixth or the seventh intercostals space on the midaxillary line. Sites of the other two ports depended upon the location of the tumors. Results Out of the 34 patients with mediastinal tumors, 25 patients underwent tumor removal by VATS alone and 6 patients received VATS combined with mini-thoracotomy, while the remaining 3 patients only underwent biopsy by VATS. Postoperatively, all patients recovered uneventfully, without severe complications or mortality. Conclusions VATS is the first choice for benign mediastinal tumors, typically those in the middle and posterior mediastinum.

Objective To investigate the effects of ginsenosides Rg 3 on vasculogenic mimicry of pancreatic cancer xenograft through the establishment of pancreatic cancer cell line SW -1990 subcutaneous xenograft model .Methods After pancreatic cancer xenograft in nude mice model beening established , All the mice were randomly divided into 4 groups and treated intraperitoneally ( IP) with saline and various concentrations (5,10,20 mg/kg) of ginsenosides Rg3.To observe the effect of ginsenoside Rg3 on tumor growth.Immunohisto-chemical-PAS staining was used to detect the effects of ginsenosides Rg 3 on vasculogenic mimicry of pancreatic cancer xenograft .and mRNA and protein expression of MMP 2、MMP9 were respectively evaluated by FQ -PCR and Western blot .Results The ginsenosides Rg3 can inhibit the growth of the tumor xenografts in nude mice .The inhibitory effect is the most obvious the 20 mg/kg of ginsenosides Rg3 group.The expression of MMP-2, MMP-9 were down-regulated compare with the control group , and the difference was signifi-cant;the Immunohistochemical -PAS staining showed the number of vasculogenic mimicry (+) and CD31 (+) were less than that in the control group .Conlusion Our results demonstrate that pancreatic vascular mimicry formation can be suppressed by Ginsenoside Rg 3 though reducing the expression of MMP -2, MMP-9 in our vivo experiments ,

Objective To understand the status of post-traumatic growth of severe burn patients and analyze its influencing factors. Methods General information questionnaire and post-traumatic growth inventory (PTGI) were used to investigate thirty patients with severe burn. Multi-linear regression method was used to analyze the post-traumatic influencing factors. Results The average score of PTGI was (68.30 ± 10.90), which was in media level. The main influencing factors included burn area, active exercise, time and expense of treatment, marital status and sear proliferation. Conclusion In order to improve the post-traumatic growth,nurses should enhance psychological intervention, teach effective coping strategies and increase the social level to the burn patients.

Objective: To examine the relationship between self-management behaviors and time perspective among patients with comorbid diabetes, so as to provide the evidence for improving self-management behaviors among patients with comorbid diabetes. Methods: The patients with comorbid diabetes who were registered in the chronic disease health management system of Minhang District, Shanghai Municipality in 2021, followed up regularly, and lived in Meilong Town were recruited. Demographic information and family history of diabetes were collected through questionnaire surveys. Time perspective and self-management behaviors were assessed using the Zimbardo Time Perspective Inventory and Diabetes Self-Management Behavior Scale, respectively. The relationship between self-management behaviors and time perspective was analyzed using a multivariable ordinal logistic regression model. Results: A total of 907 patients with comorbid diabetes were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged 65 years and above, accounting for 71.89%. In terms of the types of time perspective, 280 patients were future-oriented (30.87%), 236 were balanced (26.02%), 162 were sensation-seeking (17.86%), 123 were fatalistic (13.56%), and 106 were negative (11.69%). In terms of the self-management behaviors, 46 patients were good (5.07%), 643 were moderate (70.89%), and 218 were poor (24.04%). Multivariable ordinal logistic regression analysis showed that after adjusting for age, gender, educational level, marital status, occupation status, monthly income, and family history of diabetes, the patients with comorbid diabetes who had a future-oriented time perspective had better self-management behaviors (OR=1.874, 95%CI: 1.204-2.915). Conclusion The self-management behaviors among patients with comorbid diabetes are moderate to poor, and patients with a future-oriented time perspective can better engage in self-management behaviors.

ObjectiveTo investigate the event-based prospective memory (EBPM) and time-based prospective memory (TBPM) in patients with Alzheimer' s disease (AD). MethodsTwenty patients with AD, 20 adults with amnesia mild cognitive impairment (aMCI) and 30 healthy adults with matched age and education level were assessed with a battery of neuropsychological tests including EBPM and TBPM tasks.ResultsCompared with healthy elders and patients with aMCI on performance of PM (2. 23 + 0. 77,4.83 ±1.09;1.00±1.03,3. 10 ± 1.52) and episodic memory(0. 70 ±0. 12,0.66 +0. 16;0.45 ±0.07,0.54±0. 10), AD patients were all impaired in PM and episodic memory(0.20 +0.41,2.05 ± 1.43;0.33±0. 12,0.32±0. 10), and were impaired in EBPM more significantly (t=-2.792, P＜0.01;t =-10. 761 ,P ＜0. 01 ). ConclusionsThese results suggest that AD patients show deficits of PM, but their EBPM is impaired more significantly. EBPM impairment may be an early diagnostic of AD.

Objective:To identify the differences in clinical manifestations between Chinese giant cell arteritis (GCA) patients and polymyalgia rheumatica (PMR) patients.Methods:Twelve GCA patients were included during September 2010 to September 2019 in our hospital. Clinical and laboratory data were collected. Twenty-four age and sex-matched pure PMR patients were selected as control. Statistical analysis was performed using Statistical product and service solutions (SPSS) software. The categorical variables were tested by chi square test, and the continuous variables were expressed by mean and standard deviation ( ± s). The comparison between groups was conducted by t-test. P<0.05 was considered statistically significant. Results:In these 12 GCA patients, the onset age was 55-70 (67±7) years old, and male to female ratio was 1∶11. The most common initial symptom of GCA was the same as PMR (7/12, 58%) . Compared with PMR patients, the specific clinical manifestations of GCA patients were scalp pain ( P=0.031), mandibular claudication ( P=0.031) and migraine ( P=0.000). The creatine kinase of GCA (60±27) U/L patients was higher than that in PMR (41±15) patients ( t=1.098, P=0.029). There was no significant difference in other laboratory tests including erythrocyte sedimentation rate, C reactive protein level. Seven of 12 GCA patients were first diagnosed with PMR, then were diagnosed with GCA during follow-up. No obvious differences could be found in clinical manifestations between these 7 patients and 24 pure PMR patients. Through imaging examinations, we found that 9 of the 12 GCA patients had arterial stenosis, 5 had thickened vascular walls, 5 had atherosclerosis, and 2 had rough endometrium. Conclusion:GCA patients and PMR may have similar clinical presentations. The presence of scalp pain, mandibular claudication and migraine during the course of the disease implies that GCA is more likely. Vascular ultrasound, arterial CTA, and positron emission tomograph (PET)/CT play an increasingly important role in the diagnosis of GCA.

Objective To investigate the effect of rivanol induction on pregnancy termination for patients with placenta previa during midtrimester.Methods From January 2010 to December 2015,16 patients of placenta previa underwent pregnancy termination induced by rivanol during midtrimester were regarded as the observation group, and 22 patients with normal placental position were regarded as the control group.The delivery time,amount of postpartum hemorrhage within 24 hours,one-time success rate of induced abortion,caesarean due to massive haemorrhage and postoperative infection of the two groups were recorded to analyze the clinical effect of rivanol.Results There was no statistically significant differences in the success rate,delivery time and caesarean due to massive haemorrhage between the two groups(P>0.05).The amount of intrapartum and postpartum hemorrhage in the observation group was more than that of the control group,with a statistically significant difference(P<0.05),but it was less than 500 mL,which did not significantly increase the related risk for patients.Conclusion Induced abortion by rivanol is a simple,safe and effective method for patients with placenta previa during midtrimester with fewer side effects and less trauma,which is the preferred method for such patients.
