Objective To observe the expression of matrix metalloproteinase(MMP-2, MMP-9 and vascular endothelial growth factor (VEGF) in retinoblastoma (RB) and its relationship with the differentiation and optic nerve infiltration of RB. Methods Forty paraffin specimens of pathological confirmed RB were studied. They were divided into differentiated group (15 cases) and undifferentiated group (25 cases) , optic nerve infiltration group( 13 cases) and without optic nerve infiltration group(27cases). The expression of MMP-2, MMP-9 and VEGF were detected by immunohistochemistry, their relationships with the differentiation and optic nerve infiltration were also analyzed. Results The positive rate of MMP-2, MMP-9 and VEGF expression in 40 RB cases were 52.5%, 57.5% and 72.5%respectively. The expression of MMP-2, MMP-9 and VEGF in the undifferentiated group were significantly higher than those in the differentiated group (χ2= 9. 037, 9. 253, 8. 095;P＜0. 05). The expression ofMMP-2, MMP-9 and VEGF in RB with optic nerve infiltration group were significantly higher than those in RB without optic nerve infiltration group (χ2=11.045,10. 243, 8. 956;P＜0. 05). The expression of MMP-2,MMP-9 had a positive correlation with the expression of VEGF in RB (r= 0. 126, 0. 314;P ＜ 0. 05).Conclusions MMP-2, MMP-9 and VEGF expressed in RB tumor tissues. The expression of MMP-2,MMP-9 has a positive correlation with the expression of VEGF. The levels of MMP-2, MMP-9 and VEGF expression are related to optic nerve infiltration of RB cells.

Objective To investigate the clinical effective of laparotomy or laparoscopic total mesorectal excision surgery for patients with colorectal cancer. Methods One hundred and one patients with colorectal cancer in the Beijing Jiangong Hospitalour were selected as our subjects and divided into control group and treatment group. Patients in control group were received laparotomy and patients in treatment group were performed laparoscopic total mesorectal excision surgery. Clinical effective were recorded. Results The blood loss volume,postoperative discharge time,postoperative indwelling catheter time,hospital stay in treatment group were(143. 9 ± 32. 3)ml,(3. 1 ± 1. 2)d,(3. 5 ± 1. 4)d and(11. 9 ± 2. 1)d,less than those in control group ((198. 9 ± 41. 2)ml,(5. 3 ± 1. 3)d,(6. 1 ± 1. 5)d and(16. 9 ± 2. 3)d respectively). And the differenced were significant(t = 4. 994,9. 858,6. 543,6. 593;All P < 0. 05). The operation time,hospital cost in treatment group were(213. 4 ± 45. 3)min,(3. 5 ± 0. 5)ten thousands,higher than those in control group((153. 4 ± 43. 4)min, (2. 8 ± 0. 4)ten thousands),and the differences were significant(t = 7. 653,6. 593;P < 0. 05). There was no significant difference between the two group in term of the number of resected lymph nodes( t = 0. 882,P> 0. 05). There were no significant difference between two group in terms of NK,CD3 + ,CD4 + and CD8 + level (P > 0. 05)at before treatment. The NK,CD3 + ,CD4 + and CD8 + levels in control group after treatment were 8. 3 ± 0. 9,(64. 5 ± 4. 8)% ,(34. 3 ± 3. 0)% and(32. 8 ± 2. 4)% and those were 13. 0 ± 1. 0,(71. 9 ± 5. 1)% ,(45. 2 ± 3. 2)% and(26. 1 ± 2. 2)% in treatment group after treatment. The differences were significant( t = 5. 488,8. 481,4. 954,7. 493;P < 0. 05 ). The wound infection rate of control group was significantly higher than this of treatment group(1. 8% vs. 11. 4% ;χ2 = 4. 103;P < 0. 05). There was no significant difference between the two group in terms of other complications( P > 0. 05). Conclusion The clinical effective of laparoscopic total mesorectal excision surgery is better than laparoscopic surgery.

Objective To explore the preventive effect of feedforward control on unexpected extubation in patients with cerebral apoplexy.Methods The clinical data of 42 cerebral apoplexy patients during May 2010 and May 2011 were retrospectively reviewed to find out the risk factors of unexpected extubation.The feedforward control was used to manage 49 cerebral apoplexy patients during June 2011 to June 2012 to control the risk factors.The incidence of unexpected extubation was compared between pre-and post-use of feedforward control. Results After application of feedforward control,the incidences of unexpected extubation of gastric tube,deep vein tubes and urinary tubes reduce were significantly decreased compared to pre-use of feedforward control(all P<0.01).Conclusion The feedforward control on patients with cerebral apoplexy is effective in reducing the incidence of unexpected extubation and ensuring the intubation safety.

Schizophrenia is roughly equivalent to insanity in TCM.Premorbid personality traits of schizophrenia are similar to the characteristic of stagnation of liver in TCM.The stagnation of liver-qi is a usually cause and main differentiation type of schizophrenia.Early location of this disease is toward to the liver.The stagnant qi of the liver turns into fire,up to brain to interfere the activity of mind,then leads the disease into the acute phase;Stagnation of the liver-qi and the heart-fire affect other organs and lead the disease to its chronic phase:The change of solar term or dramatic disturbances of climate change often leads liver yang to interfere the mind,resulting in recurrence or relapses of schizophrenia.We should pay attention to rule of liver in the treatment,rehabilitation,prevention of recurrence in schizophrenia.When treating schizophrenia,we need pay attention to soothing liver,without inhibiting the sthenic liver-energy;suppressing the hyperactive liver by calming the liver and removing heat from the liver.Soothing liver and strengthening spleen,dispersing liver-qi and regulating stomach are the common treatment.For preventing degeneration,while nourishing liver and kidney,clearing heat and calming the mind should be used at same time;while nourishing liver yin,wind-dispersing,eliminating phlegm,clearing-stasis should be used at same time.Cleaning liver heat,nourishing yin,activating blood and detoxification should be paid attention to when preventing and treating the side effects caused by antipsychotic drugs.

Objective To evaluate the outcomes of distraction osteogenesis with mini external fixation in management of metacarpophalangeal bone defects after hand trauma.Methods From June 2010 to December 2015,16 patients with metacarpophalangeal bone defects after hand trauma received distraction osteogenesis at our department.They were 11 men and 5 women,from 20 to 45 years of age (average,32.5 years).There were altogether 20 bone defects:8 cases had single metacarpal bone defect,2 unilateral second and third metacarpal bone defects and 6 phalangeal shortening after repair of digital stump (involving thumb in 4 cases,index finger in one and index and middle fingers in one).The metacarpophalangeal bone defects averaged 1.8 cm (from 1.0 to 3.1 cm).Under the fluoroscopic guide,4 or 6 mini half-pins in one line were directly drilled into the dorsal aspect of the involved metacarpophalangeal bone before the Orthofix fixator was mounted.The proximal (18 digits) or distal (2 digits) osteotomy between the second and third pinholes was performed via the dorsal approach,The external fixator and pins were removed without anesthesia after callus maturation.Results Average follow-up period was 12.2 months (range,from 9 to 26 months).All the metacarpal bone defects were reconstructed and all the phalangeal shortenings were lengthened;the bony callus was completely calcified at the lengthened part.The mean lengthening was 1.9 cm (from 1.0 to 3.1 cm);the percentage of lengthening ranged from 26％ to 51％ (average,34％).The bone lengthening index (time cost by average 1 cm) was 70.9 d/cm (from 60.0 to 87.1 d/cm).According to the Tentative Assessment Criteria for Upper Extremity Function by Hand Surgery Society,Chinese Medical Association,the total activity of motion (TAM) was excellent in 13 cases,good in 4,fair in 2,and poor in one,yielding an excellent to good rate of 85.0％.Conclusion Distraction lengthening using mini external fixation is a valid option with a minor rate of complications which allows for early functional exercise to help restore the appearance and function of the affected fingers.

Objective To assess the efficacy of ganciclovir to prevent and cure cytomegalovirus (CMV) infection after renal transplantation. Methods We searched PubMed, EMBASE, Cochrane Library, SCI, China Academic Journals Full-text Databases, Chinese Biomedical Literature Database, Chinese Scientific Journals Databases and Chinese Medical Association Journals to collect randomized controlled trials of ganciclovir to prevent and cure CMV infection after renal transplantation (up to June, 2009). Two reviewers extracted data independently using a designed extraction form. The quality of included trials was evaluated according to the Cochrane Handbook. RevMan 5.0 software was used for data analysis. Results Twelve randomized controlled trials were included. The results of meta-analysis showed that: ①Compared with no receive antiviral agents, ganciclovir couldn't lower CMV infection rate and disease rate in 3 months and 6 months after renal transplantation, but could lower CMV disease rate in 12 months. The delay between transplantation and CMV infection was significantly longer. ②Either valaciclovir or ganciclovir could lower CMV infection rate and disease rate after renal transplantation, without statistical difference. ③Compared with acyclovir, ganciclovir could lower CMV disease rate in 6 months after renal transplantation. ④Compared with CMV-IgG and valganciclovir, ganciclovir didn't have statistical difference in decreasing CMV disease rate (P=0.93;P=0.14). Conclusions Longer prophylaxis by ganciclovior may prevent CMV infection after renal transplantation. Its curative effect is similar to valaciclovir, CMV-IgG and valganciclovir, but better than acyclovir.
