Objective To explore the feature and strategy of psychic behavior of patients of malignant tumor.Methods Chosen 315 patients of malignant tumor randomly from September of 2005 to May of 2008 and filled in the 《analytical table of psychic behavior of malignant tumor》by method of answer roll and analyzed.Results Psychic symptoms of patients of malignant tumor have some features,such as early appearance,serious symptoms,easy to neglect,and so on.Conclusions Psychic symptoms of patients of malignant tumor should be diagnosed and treated promptly and think highly by the doctor、patient and society.We should construct more consummate social support system and treatment system and raise recognition to disease by patient themselves.

Objective To investigate the effects of tramadol hydrechloride pretreatment on the expression of calcitonin gene-related peptide (CGRP) in ischemic and non-ischemic myocardium following acute myocardial is-chemia in the rats. Method Eighteen adult male SD rats weighing 270 to 300 g were randomly divided into three groups(n = 6, in each): group Ⅰ ,sham operation; group Ⅱ , myocardial isehemia, and group Ⅲ, tramadol hydrochloride pretreatment. The anterior descending branch of left coronary artery was occluded(CAO)for 3 hours in rats of group Ⅱ and Ⅲ. In group Ⅲ, tramadol hydrochloride 12.5 mg·kg~(-1) was injected through caudal vein 15 minutes before CAO. At 3 hours after myocardial ischemia, the hearts were removed for determination of CGRP protein content in ischemic and non-ischemie myocardium by immuno-histochemistry and enzyme immunometric as-say, and the expression of CGRPmRNA by RT-PCR. One-way ANOVA was used for statistical analysis. ResultsOnly β-CGRPmRNA was found in rats myocardium. In the ischemic myocardium, the average light density of CGRP(0.215 ± 0. 100), positive unit (36.95 ± 1.70), concentration (39.06 ± 1.86) and expression of β-CGRP mRNA 0. 946 ± 0. 019) were significantly increased in group Ⅱ compared with those in group Ⅰ (0. 139 ± 0.006), (25.01 ± 1.03), (20.80± 1.24), (0.734±0.025) (P <0.05), and decreased markedly in group Ⅲ(0.158+0.008),(28.53±1.21),(28.58±2.10),(0.872±0.024) (P < 0.05) In the non-ischemic my-ocardium, the average hght density of CGRP(0.156 ± 0.017), positive unit(28.57 ± 2.23), concentration (28.58 ± 1.12) and expression of β-CGRP mRNA(0.810 ± 0.021) were significantly increased in group Ⅱ com-pared with those in group Ⅰ (0.109+0.013, 20.91 ～2.14, 17.35+2.72, 0.701 ～0.018) (P < 0.05), and decreased markedly in group Ⅲ(0.120±0.008), (22.58±1.18), (23.26±2.41), (0.779±0.022) (P < 0.05). Conclusions Tramadol hydrochloride pretreatment can significantly inhibit increase in CGRP expression in myocardium elicited by CAO, which might imply that tramadol hydrochloride might take part in protection of my-ocardium against acute myocardial ischemia by means of pain-relief.

Objective To investigate the effects of morphine and tramadol pre-emptive use on the expressions of substance P mRNA (SPmRNA) and calcitonin gene-related peptide mRNA (CGRPmRNA) in dorsal root ganglia (DRG) following acute myocardial ischemia in the rats. Method Twenty-four adult male SD rats weighing 270 to 300 g were randomly (random number) divided into four groups (n = 6, in each): group Ⅰ(sham operation), group Ⅱ (myocardial ischemia), group Ⅲ (morphine pre-emptive use) and group Ⅳ (tramadol pre-emptive use). The left anterior descending branch of coronary artery was occluded (CAO) for 3 hours in rats of group Ⅱ and Ⅳ.In group Ⅲ morphine 1.25 mg·kg-1 was injected through caudal vein 15 minutes before CAO.In group Ⅳ,tramadol 12.5 mg·kg-1 was daministered via caudal vein 15 minutes before CAO.In 3 hours after myocardial ischemia, the tissue of DRG (T1-5) were taken for detecting the expressions of SPmRNA and CGRPmRNA by using RT-PCR. One-way ANOVA was used for statistical analysis. Results In the tissue of DRG, the expressions of SPmRNA(0.93±0.02) ,α-CGRP mRNA(0.98±0.02) and β-CGRP mRNA(0.83 ± 0.02)were up-regulated in group Ⅱ compared with those in group Ⅰ (0.84±0.04),(0.86±0.01),(0.45±0.03) (P ＜0.05),and decreased markedly in group Ⅲ (0.88 ± 0.03) ,(0.90 ± 0.02), (0.67 ± 0.02) (P ＜ 0.05) and group Ⅳ (0.88±0.04) ,(0.90 ± 0.01),(0.66±0.01) (P ＜ 0.05), but showed no difference between group Ⅲ and Ⅳ (P ＞ 0.05). Conclusions Morphine and tramadol pre-emptive use can significantly inhibit the expressions of SPmRNA and CGRPmRNA in rat's dorsal root ganglia after CAO.

Objective To introduce a new computer-assisted external frame for osteotomy to correct complex tibial and fibular deformity.Methods From January 2012 to December 2013,15 patients with complex tibial and fibular deformity were treated with a computer-assisted external frame and related computer software for surgical correction.All were unilateral limb deformity,involving the left lower limb in 8 cases and the right lower limb in 7 cases.They were 8 males and 7 females,15 to 43 years of age (average,26.8 years).The deformity was caused by old osteomyelitis in 9 cases and trauma sequela in 6.The related angles,distances and rotations were measured on the postoperative radiographs of the lower limbs.The data were input into the software to calculate the daily adjustment lengths of the frame rods.Daily frame adjustments were conducted according to the data calculated.The frame was removed when expected results were achieved.The patients lived independently during the adjustment.Results The 15 patients were effectively followed up for 10 to 22 months (average,15 months).Frame fixation time averaged 8.4 months (from 5.5 to 13.1 months).The reunion time averaged 8.0 months (from 5.4 to 12.1 months).The hospitalization time averaged 2.4 months (from 2.0 to 2.8 months).In 10 cases of limb shortening,the shortening lengths averaged 0.5 cm (from 0 to 0.9 cm) after adjustment.In 12 cases of angulation deformity,the angulation averaged 3.3° (from 0° to 5.4°) after adjustment.In 5 cases of rotation deformity,the maximum internal rotation was 5° and the maximum external rotation 10° after correction,deviating from the normal values by 3.5° on average.In 6 cases of horizontal displacement,the displacements averaged 0.5 crn after correction.All patients were satisfactory with corrected lower limb alignment,improved symptoms and appearance,giving a subjective satisfaction rate of 100％.Conclusion Use of computer-assisted external frame in surgical correction of tibial and fibular deformity can achieve satisfactory outcomes in simple,accurate,standardized,minimally invasive manners.

Objective To establish a method to isolate and cultivate rat bone marrow mesenchymal stem cells (BMSCs),and explore the feasibility of labeling in vitro,and tracing in vivo,BMSCs with chloromethyl-benzamidodialkylcarbocyanine (CM-Dil). Methods BMSCs were obtained and subsequently cultured with whole bone marrow cell culture system,and the third generation of BMSCs was harvested. The positive rates of CD34,CD44 and CD29 were detected by flow cytometry. CM-Dil was used to label BMSCs in vitro and the efficiency of labeling after 24 hours and at day 21 and 30 were examined under fluorescent microscope. Moreover,the growth curves were sketched to determine the negative effects of CM-Dil on the vitality and proliferation of BMSCs cultured in vitro. Rat model of focal cerebral ischemia was reproduced,CM-Dil labeled BMSCs were implanted into corpus striatum of rats' brain with computer-guided stereotaxis thereafter. Brain tissues were obtained to prepare frozen sections at 7th,14th and 21st day post-implantation,and the survival and distribution of labeled cells were observed with fluorescent microscopy. Results The third generation passage of cultured BMSCs grew orderly,with shape of desmocytes,and homogeneous in morphology. The positive rates of CD34,CD44 and CD29 expressions in BMSCs were 1.71%,80.32% and 84.89%,respectively. Red fluorescence was observed in CM-Dil labeled BMSCs in vivo 24 hours after labeling,with a positive rate of 100%. The fluorescence intensity of passage cultured BMSCs observed on day 21 was similar to that observed at 24 hours after labeling,but diminished on day 30. The growth,proliferation and morphology of BMSCs,were not influenced by CM-Dil labeling. On day 7,14 and 21 post-implantation,BMSCs decreased in quantity,appearing in oval or irregular shapes,and most of the cells were found around the needle tract,with a tendency of diffusion to peripheral area. Conclusion High purity of BMSCs may be obtained with whole bone marrow cell culture system from bone marrow of rats. CM-Dil labeling is easy to handle and effective,with no cytotoxicity to cells. The latest labeling period of CM-Dil is 21 days in vitro,therefore it seems to be an effective method for in vivo tracing of BMSCs in brain after implantation.
