ABSTRACT
Objective: To observe the influence of psychological intervention on pain, immune system and adrenocortical functions of patients receiving lung cancer surgery
Methods: We selected 124 patients who received surgery for treating stage I or II lung cancer and divided into experimental group and control group. The experimental group received comprehensive psychological intervention while the control group was given conventional nursing intervention. Pain of patients in two groups was evaluated by visual analog scale [VAS]. Before and after intervention, CD3[+], CD4[+], CD8+, CD4[+]/ CD8+ and free cortisol level in serum were measured. Moreover, QLQ-C30, a life quality measurement scale developed by European Organization for Research and Treatment of Cancer [EORTC] was used
Results: Compared to control group, VAS of patients in experimental group remarkably decreased before anesthesia, 6 hour, 12 hour 24 hour and 48 hour after surgery [P<0.05], and moreover, OLQ-C30 score and various factor scores [except physical symptoms] in experimental group were much higher [P<0.05]. No statistical significant difference was found in immune index between two groups before intervention [P>0.05]. Differences of CD3[+] and CD4[+] before and after intervention were both statistically significant [P<0.05], so did free cortisol level [P<0.05]
Conclusion: Comprehensive psychological intervention can effectively relieve pain, improve immune functions and enhance quality of life for patients suffering from lung cancer surgery
ABSTRACT
ObjectiveTo study the expression of matrix metallopro-teinase-2 (MMP-2),matrix metalloproteinase-9 (MMP-9) in the pancreatic carcinomas. Methods MMP-2,MMP-9 expression were detected by immunohistochemistry in surgically resected specimens ( cancer tissues,cancer-adjacent tissues and normal tissues) from 30 PC patients,11 pancreatitis patients and 6 normal patients.the results were analyzed combined with clinical pathologic characteristics.The data was analyzed by Chi-Square test.ResultsThere was no expression of MMP-2,MMP-9 in normal pancreatic tissues.Both of MMP-2 and MMP-9 expressions were 18.2％ in chronic pancreatitis titssues.Expression of MMP-2,MMP-9 were higher in cancer tissues than in cancer-adjacent tissues(63.3％ vs 23.3％,56.7％ vs 40.0％,P ＜0.05).There were positive correlation between MMP-2,MMP-9 expression and lymph nodal metastasis,tumor sizes,clinical stage and differentiation of tumor(P ＜0.05).Conclusions The expression of MMP-2 and MMP-9 was high,and linked to its unfavorable prognosis.
ABSTRACT
ObjectiveTo investigate the effects of MMI-166 on the proliferation and apoptosis of human pancreatic cancer SW1990 cells.MethodsMMI-166 of different concentrations (25,50,100 μg/ml) were used to treat human pancreatic cancer SW1990 cell for 24,48 h.Effect of MMI-166 on cell proliferation wasdetected by 3- (4,5-dimethyl-2-thiazole) -2-5-biphenly-tetrazole bromide ( MTT ) method and effect on cell apoptosis was tested by Annexin V-PI method and flow cytometry (FCM).ResultsTwenty-four hours after MMI-166 treatment of different concentrations (25,50,100 μg/ml),the inhibitory rates of the cells were (34.23±3.87)％,(44.81 ±2.01)％,(53.91 ±1.74)％,and the corresponding values were (39.95 ± 1.83) ％,( 52.26 ± 3.46 ) ％,( 63.20 ± 2.48 ) ％ at 48 h,which suggested a time-and concentrationdependent manner.The cell's apoptosis rates were (11.19 ±0.47)％,(23.01 ±0.53)％,(28.10 ± 0.52) ％ at 24 h,and the corresponding values were ( 11.19 ± 0.47 ) ％,( 23.01 ± 0.53 ) ％,( 28.10 ± 0.52)％ at 48 h,which were significantly higher than those in control group [ (0.09 ±0.12)％,P ＜0.05].ConclusionsMMI-166 can inhibit proliferation and induce apoptosis of human pancreatic SW1990 cell in a time- and concentration-dependent manner.
ABSTRACT
Objective To investigate of the MMI-166 on the expression of MMP-2,MMP-9 and the cell apoptosis of nude mouse xenografts of SW1990 human pancreatic cancer cells.Methods Establishment of control and experimental groups,randomly,the human pancreatic cancer xenograft model of SW1990 was constructed.The control group was treated with normal saline,and experimental group was treated with MML-166 (200 mg · kg-1 · d-1).The tumor volume and tumor inhibition rate was measured by vernier caliper through length and short diameter.The expression of MMP-2 and MMP-9 protein was observed using immunohistochemistry in the tumor tissues.Apoptosis index was detected by deoxynucleotidyl transferase-mediated nick end labeling (TUNEL method).Results The tumor volume of MMI-166 group (1252.30± 464.84) mm3 was less than the control group (2241.82±208.06) mm3,significantly.The inhibition rate was 34.47％ between the experimental groups (treat with MMI-166) (1.42±0.15) g and control group (2.17±0.20) g.The expression of MMP-2 (2.80 ± 1.10) ％ and MMP-9 (2.60 ± 1.52) ％ protein was significantly downregulated in MMI-166 group,compared with the control group.Apoptotic index in the experimental group (75.60±9.71) ％ was higher than the control group (17.40 ± 10.14) ％,significantly.Conclusion The mechanism of MMI-166 inhibiting pancreatic tumor growth and inducing apoptosis may be related to the suppression of MMP-2 and MMP-9 protein expression.
ABSTRACT
Parenteral nutrition (PN) was given to 40 patients with upper gastric carcinoma after proximal gastrectomies; and full enteral nutrition (EN) was subsequently given when bowels function recovered.The nutritional indicators including serum albumin ( Alb),prealbumin .(PA) and transferring,and immunological indicators including IgA,IgG,IgM,C3,C4 were measured before and 1st,8th day after operation.The data were processed by software SPSS 13.0.The average length of hospital stay was 14 d and the aerofluxus time was (58 ±6)hours.There were no changes in blood biochemistry,hepatic function and renal function pre- and post-operation( P ＞0.05 ).The nutritional and immune indicators except the IgM in 1 st day after operation were decreased significantly ( P ＜ 0.05 ).The immune indicators except the IgG in 8th day after operation were significantly improved in comparison of those before and 1st day after operation ( P ＜ 0.05 ).Post-operative complications occurred in 3 patients including 1 case of subphrenic infection and 2 cases of anastomotic leakage.After proper treatment,all patients recovered well.Combined application of EN and PN may improve nutrition and immune status of patients after proximal gastrectomy.
ABSTRACT
Objective To investigate the differentiated thyroid carcinoma diagnosis and treatment options. Methods From Feb. 2002 to Jan. 2008,78 patients received different surgical resection regarding the type of tumor size,number of tumor,ages and jugular lymphatic metastasis. Patients with unilateral differentiated thyroid carcinoma underwent the resection of ipsilateral isthmus of thyroid lobe or plus partial contralateral gland,and those with bilateral-lobe underwent total thyroidectomy or near-total thyroidectomy. High-risk patients (age >45 years,tumor size >4 cm,tumor size ≤4 cm,but surpass the envelop of thyroid) were performed by functional neck dissection or lymph node dissection of central region (Ⅵ area) besides postoperative endocrine therapy. Results Eleven cases underwent the resection of ipsilateral lobe with isthmus, 19 cases underwent surgical removal of ipsilateral lobe with isthmus plus partial contralateral gland,26 cases underwent near-total thyroidectomy and 22 total thyroidectomy. 25 cases underwent functional neck dissection, 23 cases underwent neck dissection of central region. There were 68 papillary thyroid carcinoma (87. 18%), 10 follicular thyroid carcinoma (12. 82%). There were 26 cases with lymphatic metastasis of Ⅵ area. Postoperative complications included 12 cases (15.38%) with deadlimb caused by hypocalcemia, 8 cases (10.26%) with transient recurrent nerve paralysis,2 cases (2.56%) with permanent injury of recurrent laryngeal nerves, 3 cases (3. 58%) with chylous fistula. Seventy-four(94. 87%) cases were followed up postoperatively for a period from 6 months to 6 years,which showed that no death occurred,but 6 relapsed with jugular lymphatic metastasis,after reoperation no distant metastasis occurred. Survival rate was 97. 30% (72/74). Conclusion Treatment of the differentiated thyroid carcinoma should be based on the size of tumor,number of tumor,age and jugular lymphatic metastasis. Lymph node dissection of central region was necessary for high-risk patients of differentiated thyroid carcinoma.
ABSTRACT
Objective To study the effect of nutrition support with somatostatin in patients with gastro- esophagus leakage after proximal gastrectomy. Methods 6 patients with gastro-esophagus leakage after proximal gastrectomy for gastric cancer from July 2004 to September 2009 were enrolled. Then, the patients were treated with improved drainage, parenteral & enteral nutrition and somatostatin. Furthermore, nutrition index and duration of recovery were investigated respectively. All data were analyzed between preoperative and postoperative by student's T-Test.Results 6 patients were cured after non-operation. The average period of in-hospital was 32 days. Compared with the post-leakage day 1 ,the nutrition states were significantly improved when patients recovered( P ＜0. 01 ). Non-complication happened. Conclusion It was an effective way to improve the nutrition state and to promote the gastro-esophagus leakage healing.
