OBJECTIVE: To probe into the status quo and future tendency of utilization of cardiovascular drugs in hospital of high altitude area. METHODS: Consumption sum and DDDs of cardiovascular drugs used in our hospital were analyzed statistically during 2006～2008. RESULTS: Consumption sum of cardiovascular drugs was increased year by year as well as its percentages in the total consumption sum. Top 10 cardiovascular drugs in terms of consumption sum mainly included antianginal drugs, antihypertensive drugs, blood fat harmimegathy drugs and antithrombotics drugs. Consumption sum of antianginal drugs which had occupied 44% in that of cardiovascular drugs took the dominate place in three years. Consumption sum of antihypertensive drugs was increased fast as well as its percentage in cardiovascular drugs about more than 20%. Consumption sum of antithrombotics drugs had occupied about 22%. CONCLUSION: Requirement of cardiovascular drugs was increased year by year. Cardiovascular drugs from foreign countries and joint stock take main place. It is necessary to explore domestic substitute drugs to decrease the cost of cardiovascular drugs.

Objective To evaluate hemodynamic status,pathological,imaging and ultrasound changes of residual lymph nodes from diffuse large B-cell lymphoma (DLBCL) after chemotherapy and their relationship with clinical treatment after chemotherapy.Methods 50 DLBCL patients undergoing full course of chemotherapy but still bearing residual lymph nodes were examined with ultrasound-guided lymph node biopsy.Some examinations were combined with PET-CT to analyze properties of residual lymph nodes.Results 64 lymph nodes were identified by color Doppler ultrasounda in the 50 DLBCL patients treated with full course of chemotherapy.Among them,53 lymph nodes from 42 patients did not show artery blood flow and HE staining of these lymph node biopsy met the clinical standard for complete remission.For the other 11 lymph nodes from 8 patients,ultrasound examination displayed smrounding blood flow inside.At the same time,PET-CT showed that these lymph nodes had higher SUV values,implying high metabolic state in these tissues,which was in agreement with ultrasonic examination results.However,HE staining of these lymph nodes biopsy demonstrated only residual lesion but no tumor tissue.Conclusions Lymph nodes still exist in DLBCL patients treated with full course of chemotherapy.Ultrasound and PET-CT examination have high accuracy in diagnosing benign and malignant residual lymph nodes in follow-up examination on 4 weeks after chemotherapy showed that lymph nodes are over ＞ 1.5 cm in length and have central or peripheral blood flow.Therefore,PET-CT examination of tumor could be considered as a reference index in characterizing residual tumors after chemotherapy.

Objective To evaluate the significance of immediate early 1 (IE) mRNA detection by nucleic acid sequence-based amplification (NASBA) in the diagnosis of human cytomegalovirus (HCMV) infection after renal transplantation.Methods The expression of IE-mRNA and pp67-(mRNA) was detected by NASBA in 55 patients after renal transplantation, and pp65 antigenemia (assays) were done for all cases.Results Twenty cases were positive for IE-mRNA. Thirteen cases were suffered from CMV disease with symptoms. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of IE-mRNA by NASBA were 92.3 %, 80.9 %, 60.0 % and 97.1 %, respectively. Time to first IE-mRNA positive detection after transplantation was shortest, compared with pp67 and antigenemia (P

Objective To evaluate carbon lymph tracer (CH40) in pancreatic cancer surgery.Method 61cases of pancreas head carcinoma undergoing whipple procedure from June 2011 to December 2013 were divided into intraoperative nano carbon group (group A,36 cases),in which resection range was adjusted according to lymph node staining including 13 standard resection cases (group A1),and 23 modified extended radical resection cases (group A2).Standard group (group B,n =17),and extended radical operation group (group C,n =8),respectively.Results The average lymph nodes harvested in group A1 were 25.08 ± 2.72,with positive lymph nodes of 7.92 ± 2.22,significantly more than group B (19.47±1.55,2.68 ±5.24),P＜0.05.In group A2,the average lymph node was 29.91 ±2.68,positive lymph node was 11.04 ± 2.38,significantly more than group C (25.13 ± 2.85,8.49 ± 3.32),P ＜0.05.The mean survival time and overall survival time of group A1 were 43.80 ±4.09 months,51.44 ±1.64 months,significantly more than group B (27.11 ±3.36,41.74 ±3.28 months),P ＜0.05.In group A2,the average tumor free survival time,and overall survival time was 31.58 ±2.99 months,45.02 ±2.54 months,not statistically different with group C (29.13±4.76 month,43.67 ±3.33 months),P ＞0.05.Conclusions Intraoperative lymphatic tracer technology significantly increases lymph node harvest,improving the survival time and tumor free prognosis.

Objective To detect the expressions of COX-2 and VEGF-C in breast cancer and to explore the relationship between their expressions and lymphatic metastasis. Methods Immunohistochemical stai- ning (SABC) was used to detect the expressions of COX-2 and VEGF-C proteins in 60 cases of breast canc- er. Results The positive rate of COX-2 and VEGF-C in breast cancer were 66.7% and 60. 0%, and the expression of COX-2 was positively correlated with VEGF-C (r =0.429, P<0.05). COX-2 and VEGF-C expressions were positively correlated with lymphatic metastasis (P<0.05). The lymphatic metastasis rate in the positive group of COX-2 and VEGF-C were higher than that in the negative group of COX-2 and VEGF-C. Conclusion Over expression of COX-2 and VEGF-C were observed in breast cancer, and closely related to lymphatic metastasis. COX-2 has positive correlation with VEGF-C and was correlated with lym- phatic metastasis of breast cancer. COX-2 may promote the over expression of VEGF-C in tumor cells and cause lymphatic metastasis.

OBJECTIVE: To analyze the causes for misplacement of pedicle screw in thoracolumbar spine.METHODS: From January 2002 to January 2008, 19 patients with misplacement in thoracolumbar spine were treated in Department of Orthopedics, Wuxi Affiliated Hospital of Nanjing University of Chinese Medicine, including 12 males and 7 females with an average age of 52.5 years (range 23-68 years). The diagnoses were thoracolumbar fracture in 5 cases, lumbar spondylolisthesis in 8 and degenerative lumbar disease in 6. The fixation systems were Steffee used in 4 cases, DRFS in 3, RF in 6, AF in 4 and GSS in 2. X-ray and CT scanning were used to observe pedicle screw location, including screw,pedicle and membranous sac and great vessels.RESULTS: The time of misplacement of pedicle screw was 5-69 days with an average time of 18.5 days, including 7 cases of screw penetrating into lateral cortex, 4 of screw penetrating into medial cortex, 2 of screw penetrating into pedicle cortex, 2 of overplacement, 2 of intervertebral foremen placement and 2 of intervertebral space placement.CONCLUSION: The causes for screw misplacement were anatomic variation and poor surgical skills, and the key factors in precise insertion of pedicle screw are fine surgical skills, carefully study of preoperative image and the intra-operative monitoring.
