Gastrointestinal stromal tumors(GISTs) are rarely one of gastrointestinal carcinomas that originate from mesenchymal tissue.GISTs are characterized by expression of CD117 receptor in cells and have variable biological phenotypes ranging from benign to highly malignant.The most common complaints of patients with GISTs are abdominal pain,peptic ulcer,bleeding or/and obstruction in digestive tract.GISTs have an extraordinarily high rate of recurrence after surgical resection and are highly resistant to radiation and standard chemotherapy.The imatinib mesylate(Gleevec) is a selective inhibitor of the tyrosine kinase receptor.The outcome for the patients with GISTs treated by Gleevec was promising in terms of immediate response and survival fraction.Recent research shows that a new targeting therapeutic agent,SU11248,can prolong the survival time of the patients with GISTs who were resistant to Gleevec therapy.

Objective:To compare lumbar fusion effect of unilateral and bilateral internal fixation for lumbar disc herniation, to explore more effective, reliable treatment. Methods:112 cases of lumbar selects my courtyard 2007 April-2010 year in April admitted to the disc herniation were randomly grouped, unilateral group and bilateral group with 56 cases in each group, respectively, to take unilateral or bilateral internal fixation for the treatment of lumbar fusion operation, compared two groups of patients and the therapy effect. Results:the unilateral group operation time, amount of bleeding during the operation and hospitalization expenses below the bilateral group, there was significant difference(t=8.857, t=9.620, t=12.338;P<0.05), the two groups had no significant difference (P>0.05);the two group patients after VAS and ODI were significantly decreased (P<0.05), before and after the treatment of VAS and ODI the comparison between the two groups were not statistically significant difference (P>0.05);the unilateral group at the end of the follow-up of 50 cases of intervertebral fusion, the fusion rate was 96.2%, the bilateral group interbody fusion in 52 cases, the fusion rate was 100%, two groups of patients at the end of the follow-up intervertebral fusion rate has no obvious statistical difference (x2=0.372, P<0.05);unilateral group were no significant complications, bilateral group were found 1 cases of intervertebral fusion device implant bone absorption, 1 cases highlight the root symptoms, complication rate was 3.8%, the two groups of patients with complications were no significant statistical difference. Conclusion:Lumbar unilateral and bilateral internal fixation can effectively improve the patients with lumbar disc herniation pain symptoms, and has good fusion degree, high security, and unilateral internal fixation operation time is shorter, less blood loss and the burden of patients is smaller, need operation treatment for severe lumbar disc herniation, fusion and unilateral internal fixation for the treatment of recommend the use of lumbar.

Objective To explore the significance of blood lactic acid level and lactic acid clearance in evaluating the prognosis of septic shock.Methods The blood lactic acid concentration of 64 patients with septic shock EICU ICU admission 1h inside,6,12,24 and 48h was recorded,and the lactic acid clearance was calculated 12 hours after treatment,and according to lactic acid clearance of outcome,64 patients were divided into two groups,live group and death group;Then compared blood lactic acid level and lactic acid clearance between the two groups.Results The blood lactic acid concentration of live group and death group when enter the ICU was (7.2 ±5.4)mmol/L,(9.2 ±5.6)mmol/L respectivly,and was higher than normal,and of live group after 6h began to fall,and it reached normal level after 24h [ (2.2 ± 1.3 ) mmol/L ],but of death group after 48 h [ ( 8.0 ± 3.8 ) mmol/L ] was still significantly higher than normal,until death.There was significant difference between the two groups (t =3.7816,3.8257,7.5263,4.5875,5.8765,all P ＜ 0.05 ).The lactic acid clearance of death group after 12 hours was (5.83 ±3.92)mmol/L,and significantly lower than that of live group[ ( 14.32 ±2.68) mmol/L] (t =6.2565,P ＜0.05).Conclusion Blood lactic acid concentration was positively related to the prognosis of patients with septic shock,and dynamic response of disease progression by detecting lactic acid clearance rate could be early,sensitive,quantitative indicators to determine the severity of critical illness.

Objective To investigate the effect of immediate hyperbaric oxygen on focal cerebral ischemia of rats. Methods Sprague-Dawly rats were randomly divided into control group (n=9), hyperbaric air group (n=9), hyperbaric oxygen group (n=9) and sham group (n=5). The middle cerebral arteries were occluded in the former 3 groups, while the hyperbaric air group and the hyperbaric oxygen group operated in the hyperbaric chamber, and the hyperbaric oxygen group accepted hyperbaric oxygen immediately after operation. All the rats were sacrificed 6 hours after operation and the percentage of volume of infarction in the brain slices was calculated. Results The percentage of infarction decreased in both hyperbaric oxygen group and hyperbaric air group compared with the control group (P<0.001), and decreased more in the hyperbaric oxygen therapy than in the hyperbaric air group (P<0.001). Conclusion Immediate hyperbaric oxygen therapy can reduce infarct size in rats after focal cerebral ischemia.

AIM: The reasons of explicit and occult Descemet's membrane detachment ( DMD ) after phacoemulsification were analyzed and the therapeutic measures were further provided.
METHODS:A total of 31 cases diagnosed as explicit and occult DMD between Jan. 2013 and Apr. 2016 received the injection of sterile air into anterior chamber by 1-3 times, and were followed up for 3mo to observe the recoveries of cornea.
RESULTS: A total of 30 cases recovered with no visual impairment and other related complications. One case which refused being treated resulted in bullous keratitis.CONCLUSION:Both the internal and external factors can influence the operation effect of explicit and occult DMD after phacoemulsification. Early detection and timely treatment play important roles in improving patients'visual acuity. Early examination of anterior segment OCT or UBM for intractable corneal edema is helpful to find the occult DMD with different degree and work out the targeted therapies.

OBJECTIVE:To analyze the clinical application and trend of antitumor drugs in 42 hospitals from Beijing,Shang-hai and Chengdu,and to provide reference for rational drug use in clinic. METHODS:The utilization of antitumor drugs in 42 hos-pitals from Beijing,Shanghai and Chengdu during 2012-2016 was analyzed statistically in respects of consumption sum,DDDs. RESULTS:The consumption sum of antitumor drugs in 3 cities,Beijing ranked the first;annual growth rate of Shanghai was the highest. In the list of consumption sum of antitumor drugs of 3 cities in 5 years,immunosuppressive agents as tacrolimus,mycophe-nolate mofetil were among top 10 antitumor drugs in the list of consumption sum. Top 1 antitumor drug in the list of consumption sum in Beijing,Shanghai and Chengdu were thymopentin,tacrolimus and thymalfasin,respectively. Among subtype of antitumor drugs,other antitumor drugs and adjuvant drugs in Beijing and Chengdu during 2012-2014 took up the first place in the list of con-sumption sum;the consumption sum of antimetabolite during 2015-2016 occupied the first place,and that of Beijing was higher than that of Chengdu. The cost of antimetabolite in Shanghai during 2012-2016 was the highest. The consumption sum of other antitumor drugs and adjuvant drugs were the highest in 3 cities during 2012-2014;that of antimetabolite was the highest during 2015-2016. Among related drugs,immune enhancer,immunosuppressive agents and analgesics ranked the top in the list of consumption sum. Among top 10 antitumor drugs in the list of DDDs,most were antineoplastic medicine,and only cyclophosphamide among alkylat-ing agents entered the ranking. CONCLUSIONS:The growing trend of antitumor concumption sum is stable. Antimetabolite,hor-mones and plant-derived antitumor are becoming larger. Molecular targeted therapies have a good prospect for application.

Objective To explore the clinical effect of ligament advanced reinforcement system ( LARS) artificial ligament reconstruc-tion of the anterior cruciate ligament ( ACL) in the operation. Methods Sixty patients with ACL injury in our hospital from September 2011 to May 2013 were randomly divided into LARS group and autologous hamstring tendon ( group ST/G) group with 30 cases in each group,the Lysholm score,IKDC score,the difference of clinical effect and bone tunnel of patients in two groups before treatment and at 3rd,6th,9th, 18th months after treatment were compared. Results The time of walking with crutch,ambulation and restore movement in LARS group were obviously shorter than those in ST/G group(P<0. 05). The Lysholm score,IKDC score,the difference of clinical effect and bone tunnel of patients in two groups after treatment were better than those before treatment(P<0. 05). The difference of Lysholm score and IKDC score be-tween two groups before operation was not significant (P>0. 05). The Lysholm score and IKDC score of LARS group at 3rd,6th,9th months after operation was higher than that of ST/G group,and at 18th months after operation,the difference of Lysholm score and IKDC score be-tween two groups was not significant (P>0. 05). At the last follow-up,the distribution effect of LARS group was higher than that of ST/G group (P<0. 05). The excellent and good rate of LARS group (93. 33%) was higher than that in ST/G group(76. 67%),but the difference was not significant (P>0. 05). There were 6 cases of patients with bone tunnel enlargement in LARS group,14 patients had bone tunnel en-largement in ST/G group. The bone tunnel enlargement rate was significantly higher than that of the LARS group (P<0. 05). Conclusion Ligament advanced reinforcement system of artificial ligament in anterior cruciate ligament reconstruction with autologous hamstring tendon re-construction can significantly speed up the recovery of the patients,and improve the postoperative curative effect and reduce the incidence of postoperative bone tunnel enlargement.
