Objective To observe inhibiting effect of endostatin on subcutaneous transplant tumor of breast carcinoma, and to illuminate the therapeutic effect of endostatin in the cancer. Methods The effect of en-dostatin on MCF-7 cell proliferation was studied by MTr. The model of MCF-7 cell transplant tumor on nude mice was constructed. Endostatin was injected intradermally around the transplant tumor. Inhibition effect on the tumor was observed. Results Endostatin with the concentration of 10 μ/mL and 15 μg/mL can inhibitMCF-7 cell proliferation effectively (P < 0. 05 ). After endostatin injection, tumor weight, volume and mi-crovessel density decreased significantly(P < 0.05 ). Conclusion Endostatin can inhibit breast carcinoma proliferation through inhibiting angiogenesis and the tumor cell itself.

Objective To study the clinicopathologic features and differential diagnosis of deep angiomyxoma(DAM). Methods Seven cases of DAM were collected from 2000 to 2008. All the patients were examined by microscopy and immunohistochemistry. Results 6 patients with DAM were females and 1 was male, with median age of 48.5 years. Median maximum dimension was 5.9cm, with invasive growth pattern. The tumor cells of DAM were infantile, spindle or stellate,diffuse and nodular arrangement. A distinctive histologic feature of DAM was its vascularity. Non-arborizing, thin-wall, ectastic capillaries or more commonly, small thick-wall vessels were dispersed throughout the tumor. Mast cells and extravasated red blood cells were frequently found in the stroma, immunohistochemical study showed that 7 cases were positive for vimentin, desmin, ER and PR, 5 for CD34 and SMA, and negative for S-100 and CK. Conclusion DAM is a rare soft tumor that occurs principally in the vulval and vagina region of woman. Misdiagnosis has happened frequently. Immunohistochemical staining are helpful to diagnosis for DAM, but no significance to distinguish it.

Objective To investigate the effects of different duration of sevoflurane anesthesia in the neonatal period on the long?term cognitive function and hippocampal synaptic plasticity in rats. Methods Twenty?four pathogen?free healthy Sprague?Dawley rats of both sexes, aged 7 days, weighing 12-16 g, were divided into 3 groups ( n=8 each) using a random number table: control group ( group C) , sevoflu?rane anesthesia for 2 h group ( group S1 ) , and sevoflurane anesthesia for 6 h group ( group S2 ) . Group S1 and group S2 inhaled 2% sevoflurane for 2 and 6 h, respectively. Morris water maze test was performed at 30 days after the end of anesthesia ( postnatal day 37) to assess the cognitive function. After the end of the test, the rats were sacrificed, and hippocampi were isolated for determination of the expression of brain?de?rived neurotrophic factor ( BDNF) , postsynaptic density?95 ( PSD?95) and synapsin 1 in hippocampal tis?sues by Western blot. Results Compared with group C, the escape latency on 4th and 5th days of the test in group S1 and on 2nd-5th days of the test in group S2 was significantly prolonged, and the frequency of crossing the original platform was significantly decreased, and the time of staying at the platform quadrant was significantly shortened in S1 and S2 groups, the expression of BDNF, PSD?95 and synapsin 1 in hipp?ocampal tissues was significantly down?regulated in group S2 (P<0?05), and no significant change was found in the expression of BDNF, PSD?95 and synapsin 1 in hippocampal tissues in group S1 ( P>0?05) . Compared with group S1 , no significant change was found in the escape latency and frequency of crossing
the original platform (P>0?05), the time of staying at the platform quadrant was significantly shortened, and the expression of BDNF, PSD?95 and synapsin 1 in hippocampal tissues was significantly down?regula?ted in group S2 ( P<0?05) . Conclusion Short?time and long?time sevoflurane anesthesia both can induce long?term cognitive dysfunction in the neonatal period, and the severity is aggravated with prolonged anes?thesia; the partial mechanism is related to inhibition of the synaptic plasticity of hippocampal neurons of rats.

AlM: To explore the judgment of pattern reversal visual evoked potential on visual function and injured part of children with spastic cerebral palsy.METHODS: There were two groups in this study. 30 children with spastic cerebral palsy ( quadriplegia: 15, diplegia:15) were selected as observation group, while 30 normal children were selected as control group with randomized controlled trial. The changes of half-view and full- view incubation period and amplitude were observed by pattern reversal visual evoked potential.RESULTS: Full-view pattern reversal visual evoked potential: the P100 incubation period of the observation group was 113. 55 ± 8. 14ms, and the P100 amplitude was 23. 08±15. 41μV. The P100 incubation period of the control group was 105. 05 ± 5. 58ms, and the P100 amplitude was 31. 65±7. 37μV. From the comparison on P100 incubation and P100 amplitude between two groups, the difference was statistically significant ( P<0. 05 ) . P100 incubation period of the spastic diplegia of full-view pattern reversal visual evoked potential was 112. 73±7. 22ms, and the P100 amplitude was 21. 03±12. 17μV. P100 incubation period of the spastic quadriplegia was 114. 37 ± 9. 02ms, and the P100 amplitude was 25. 14 ± 18. 06μV. From the comparison on P100 incubation and P100 amplitude between two groups, the difference had no statistically significance (P>0. 05). Compared to the control group, each eye and each view latency of observation group were higher, the difference was statistically significant ( P<0. 05). The change of the incubation period of the full-view and half - view pattern reversal visual evoked potential took place in the lesion of the visual pathway:including optic neuropathy, some optic nerve lesion, lesion after optic chiasma, and optic chiasma lesion. Among them, the lesion after the optic chiasma was the most common.CONCLUSlON:Pattern reversal visual evoked potential can help people to understand the visual impairment and injury of children with spastic cerebral palsy in order to identify the abnormal children and early intervention.

Objective To summarize the treatment results,operative complications and experiences of laparoscopic modified pull-through(Soave)precedure.Methods Twenty children with Hirschsprung disease(HD),16 males and 4 females,with age from 3.5 months to 4 years old,underwent laparoscopic modified pull-through(Soave)precedure under whole anesthesia and tracheal intubation,and the pathological colon was freed by ultrasonic surgical knife.Results All cases were operated on successfully.The average operating time was 132 min.The average resection colon was 35 cm and the average volume of bleeding was about 14 mL without blood transfusion.Two patients had postoperative enterocolitis;3 patients were no complications postoperation,such as constipation,soiling,intestinal obstruction,preianal intestine prolapse or cuff narrowing,and all patients had 1-2 bowel movements per day during a period of 6 months to 3 years follow-up.Conclusion Laparoscopic modified pull-through(Soave)precedure has smaller incision,less bleeding,quick recovery and less complications.

Objective To investigate the analgesic efficacy and spinal neurotoxicity of intrathecal (IT) different doses of dexmedetomidine in rats. Methods Sixty male SD rats weighing 180-220 g were randomly divided into 5 groups ( n = 12 each): groupnormal control (group C); group IT normal saline (group N); different doses of dexmedetomidine groups received IT dexmedetomidine 0.75, 1.50 and 3.00 μg/kg respectively (groups D1.3). Paw withdrawal threshold to mechanical stimulation (PWMT)with yon Frey filaments and tail flick latency (TFL) to a thermal nociceptive stimulus were measured before (To, baseline) and at 30 or60 rin after IT dexmedetomidine or normal saline administration (T1, T2 ) and the percentage of the maximum possible effect ( MPE ) was calculated. Lumbar segment of the spinal cord ( L4-6 ) was removed for microscopic examination and determination of c-Fos expression (by immuno-histochemistry) at 7, 24 and 48 h after IT dexmedetomidine or normal saline administration. Results PWMT, TFL and the percentage of MPE were significantly increased after IT dexmedetomidine as compared with the baseline values at T0 in groups D1-3 ( P ＜ 0.05). PWMT was significantly higher at T1 and TFL and the percentage of MPE were higher at T2 in groups D1-3 than in groups C and N,and in group D3 than in groups D1,2 ( P ＜ 0.05). At 7,24 h after IT dexmedetomidine c-Fos protein expression was significantly higher in group D3 than in groups C and N( P ＜ 0.05). There was no significant difference in c-Fos expression at 48 h after IT dexmedetomidine between group D3 and groups C and N ( P ＞ 0.05 ). At 24 h after IT dexmedetomidine c-Fos protein expression was significantly higher in group D3 than in other 4 groups( P ＜ 0.05). Slight spinal cord injury was observed at 24 h after IT dexmedetomidine in group D3. Conclusion IT dexmedetomidine has antinociceptive effect. High dose dexmedetomidine IT can produce transient reversible toxicity to the spinal cord.
