Neuroendocrine tumors of the epiglottis were extremely rare. Patients normally had no obvious symptoms and signs of early stage. Epiglottis lingual except (without) tubercle of epiglottis, and hyperplastic mass were observed by using laryngoscopy and also confirmed by biopsy and immunohistochemistry. Immunohis- tochemical studies showed that Syn, a broad spectrum endocrine marker, and CgA, a specific marker of endocrine tumor, were both positive. Which is consistent with the diagnosis of neuroendocrine carcinoma.

Objective To investigate the relationship between levels of serum matrix metalloproteinases(MMPs)and brain edema and neurologic impairment in patients with intracerebral hemorrhage(ICH).Methods The levels of serum MMP-9 and MMP-2 in 31 patients with ICH were tested with ELISA for at 1 d,3 d,7 d and 2 weeks after onset.The volumes of hematoma and its peripheral edema were evaluated by CT,the neurologic impairment was evaluated by NIHSS at 1 d and 14 d after onset.Results Levels of serum MMP-9 and MMP-2 were significant higher in ICH group at each time point after onset than those in normal control group(allP

Objective To evaluate the efficacy of retroperitoneoscopic adrenalectomy for pheochromocytoma.Methods From January 2000 to October 2006,a total of 16 patients(aged from 32 to 65 with a mean of 42 years) with pheochromocytoma received retroperitoneoscopic adrenalectomy in our hospital.Among the cases,6 had the tumor on the right side,and 10 on the left.The size of the tumors ranged from 2.5 to 4.6 cm in diameter(mean,3.1 cm).Results The mean preoperative preparation time in this series was 11 days(range,6 to 28).The retroperitoneoscopic adrenalectomy was completed in all but one of the patients,who were converted to open surgery because of extensive adhesion of the tumor to surrounding tissues and massive bleeding.The mean operation time was 110 minutes(90 to 170),and the mean blood loss was 135 ml(80 to 650).Three cases,who had normal blood pressure and thus received no noradrenalin immediately after the surgery,was given noradrenalin emergently 4,6,or 56 hours later owing to a sudden drop of systolic pressure(from 135 mm Hg to 80 mm Hg in 2,and from 140 mm Hg to 85 mm Hg in 1).Postoperative examination showed benign pheochromocytoma in 15 of the cases,and low-grade malignant pheochromocytoma with local invasion of the capsule in the patient who was converted to open surgery.The mean postoperative hospital stay was 12 days(9 to 20).The patients were followed up for 3 to 24 months(mean,13),during which only one received antihypertensive drugs;the others restored normal blood pressure spontaneously.No patient had abnormal levels of 24-hour urine noradrenalin,adrenalin,and catecholamine.Conclusions Retroperitoneoscopic surgery is an effective and minimally invasive treatment for patients with adrenal pheochromocytoma.The patients have a few complications and recover quickly after the operation.Preoperative preparation and postoperative treatment are important for the outcomes of the disease.

Objective To investigate the possibility of microsatellite alteration (MA) in diagnosis of bladder cancer of Chinese people, and find the better panel which will be used in clinic. Methods A total of 6 and 10microsatellite markers were chosen, PCR-SSLP silver staining assay was performed in 31 and 32 bladder cancers tissue,exfoliate cells in urine and 10, 15 non-bladder cancers exfoliate cells in urine, respectively. Results MA (+) was found in 28 out of 31, 30 out of 32 bladder cancers, and the sensitivity was 90.3%, 93.7% respectively. The MA of urine sediment of 25 non-bladder cancers was negative, and the specificity was 100%. The cytology was carried out among 19 out of 31, 20 out of 32 bladder cancers at the same time, 2 cases ( 10.3 %) and 3 cases ( 15 % ) were found cancer positive, and the sensitivity is significantly lower than that by the analysis of MA in exfoliated cells. Conclusion MA was not associated with grade and stage of the bladder cancer. MA assay is a sensitive and effective method for the early detection of bladder cancer and post-operation surveillance.

Objective To analyze the cause of delayed hemorrhage after minimally invasive percu- taneous nephrolithotomy(MPCNL),and to summarize the experience in the interventional treatment of severe bleeding after MPCNL by superselective arteriolar embolization.Methods The clinical data of 3812 cases of MPCNL from June 1998 to July 2004 were reviewed.Of them,12 patients(11 men and 1 woman;mean age,45 years)who developed severe hemorrhage after MPCNL were identified.The cause of hemorrhage and the treatment results were analyzed.Results The rate of delayed hemorrhage after MPCNL was 0.31% (12/3812).The mean time to onset of severe bleeding was 10 d after MPCNL.Renal arteriography was per- formed in all 12 patients,showing 5 arteriovenous fistulas and 7 false aneurysms.Superselective arteriolar em- bolization for hemostasis was performed in all 12 cases.All these vascular abnormalities were successfully treated by superselective embolization.Follow-up showed that the hematuria disappeared and renal function recovered well.Conclusions Severe hemorrhage following MPCNL is a rare complication,the incidence of which is significantly lower than that of conventional PCNL.The cause is mainly the arteriolar injury of re- nal puncture passage.Superselective embolization provides effective control of bleeding and currently consti- tutes the treatment of choice based on our experience.

This article is to evaluate the correlation between dermatomal somatosensory evoked potentials(DSEP) improvement and clinical outcome in patients with lumbosacral radiculopathy received nerve root decompression.Twenty two patients diagnosed as radiculomedullary were confirmed by the CT or MRI screen,they were investigated preoperatively and 9 week postoperatively.Compared with the preoperative,the postoperative clinical symptoms of the patients were significantly improved( P

Objective To investigate the application value of anatomic segmental hepatectomy in treatment of left hepatolithus.Methods The 80 patients with left hepatolithuswere divided into the control group (n =40)and the observation group (n =40)in accordance with dif-ferent surgical methods,and they were given traditional surgery and precise pedicle anatomic segmental hepatectomy respectively.Operation index levels,postoperative complications and stress reaction levels before and after surgery of the two groups were compared.Results The blood loss,operative time,the time of drainage tube remove,time of analgesic drug use,and postoperative hospital stay of the observation group were significantly less than the control group,and the difference was statistically significant (P <0.05).The rate of postoperative com-plications was 17.50% in the control group,while it was 15.00% in the observation group,which showed no significant difference between the two groups (P >0.05).During the surgery,epinephrine,cortisol,IL-6 and CRP levels of patients decreased after a slight increase, while NK cell levels of patients decreased firstly and then increased.There were statistically significant differences in trems of the above inde-xes immediately after surgery to 24 hours after surgery (P <0.05),and the rangeability of the observation group was less than the control group (P <0.05).Until 48 hours after surgery the above indexes recovered to the preoperative level.Followed up for 3 to 24 months,the calculi recurrence rate and abdominal ache recurrence rate of the observation group were lower than the control group,and the difference was statistically significant(P <0.05).Conclusion Precise pedicle anatomic segmental hepatectomy applied in the treatment of left hepatolithus showed makedly curative effect,and it has little effect on the stress response of patients.

Objective To study the effect of the Aiyishu injection combined with chemotherapy for middle and advanced cancer patients in the near future curative effect and survival quality.Methods 127 middle and advanced cancer patients were randomly divided into two groups,71 cases in therapeutic group and 56 cases in control group.The therapeutic group and control group both choose the same sickness plants and combined chemotherapy plan of pathology,therapeutic group added the Aiyishu injection 40 ml to drip. The treatment course lasted 14 days,with 3～4 courses,Simple chemotherapy was used in the control group. Results In the therapeutic group,there were 3 cases of complete response(CR),23 cases,of partial response (PR),the rate of response is 36.62 %(26/71).In the control group,there was 1 case of complete response(CR), 10 cases of partial response(PR),the rate of response is 19.64 %(11/56).There was significant difference be- tween the two groups(P0.05),whereas it declined significantly in the control group after chemotherapy(P

Objective To investigate the effects of hemocoagulase in preventing and treating perioperative hemorrhage in patients undergoing total hip replacement and study its effects on perioperative blood coagulation function so as to provide objective basis for better clinical usage of hemocoagulase. Methods Eighty ASA Ⅰ Ⅱ patients undergoing total hip replacement under general anesthesia were randomly and equally divided into two groups, ie, Group Ⅰ (control group) that received normal saline for 4 ml iv and normal saline for 2 ml im 10 minutes preoperatively; GroupⅡ(hemocoagulase group) that received hemocoagulase for 2 kU iv and Hemocoagulase for 1 kU im 10 minutes preoperatively. The perioperative and postoperative bleeding volume was measured respectively; meanwhile, the indices of blood coagulation function were measured during operation, immediately, one and five days after operation. Results (1) The perioperative and postoperative bleeding volume in GroupⅡ was significantly less than that in Group Ⅰ ( P

Aim The changes of the levels of blood sugar and plasma insulin in obese woman pa-tients with insulin resistance and the effect of insulin intravenous infusion during oper-ation were observed. Methods 10 patients of normal weight(contrast group, group A)and 20 patients of obesity women(ASA grade Ⅰ- Ⅱ) undergoing selective surgerywere investigated. The patients of obesity were randomly divided into two groups(group B and C, respectively). Groups A and B liquids without glucose, and in group Ctransfuse liquids with glucose and insulin(4g glucose add 1U insulin) were transfusedduring operation. The levels of blood sugar and plasma insulin were measured beforeand after anesthesia, during operation(30min) and after operation respectively. ResultsThere was an insulin resistance phenomenon in patients with obesity. The levels ofblood sugar and plasma insulin in patients with obesity were remarkably higher thanthose in patients of normal weight. The levels of blood sugar and plasma insulin wereextremely raised after anesthesia and during operation. The levles of blood sugar wasinhibited as insulin was infused during operation, but no hypoglycemic reaction wasfound. Conclusion There are insulin resistance phenomenon in patients with obesity.Insulin infused during operation can prevent blood sugar rise and minimize glucosemetabolism turbulence.
