87 female patients with carcinoma of the colon and rectum were treated in our hospital from 1977 to 1986. Among them seven (8%) were found to have ovarian metastasis, The average age of the patients was 49 years. The primary tumor was mainly located in the sigmoid or ascending colon. The se-rosa was involved in all the 7 cases. Ovarian metastasis were usually bilateral. The prognosis of the patients with ovarian metastasis remained poor despite the performance of a radical operation. It is very important to consider the possibility of the ovarian metastasis in patients with colonic cancer, and prophylactic oophorectomy is imperative in order to effect a cure.

Artificial ureter has been studied for nearly 60 years, however it is still in experimental stage. So far there are no commercially available products for clinical use except autologous intestines loop even though many progresses have been made. Each approach for making artificial ureter has its own inherent advantages, disadvantages and limitations. But some approaches have shown great potential to be used as ureteral substitutes. Preventing the conduit from salt depositing and ensuring a watertight anastomoses with native tissues are the key factors in designing and manufacturing the prosthetic ureter. Along with scientific and technical improvement, artificial ureter will be successfully used in clinical therapeuticsin in the very near future.

Objective To evaluate the reliability of transcranial doppler (TCD) in detection spasm of middle cerebral artery (MCA),vertebral artery (VA ) and basilar artery (BA).Methods TCD and digital subtraction angiography (DSA) examination were undertaken in 50 patients with subarachnoid hemorrhage.Results Arterial spasm was diagnosed in 26 MCA by DSA,21 of which were detected by TCD at same time.4 MCA were showed by TCD but not confirmed by DSA. The sensitivity and specificity of TCD in diagnosing MCA spasm were 80.8% and 84.0% respectively. Higher sensitivity was revealed in those with severe MCA spasm. DSA also found out asterial spasm of BA in 18 BA,among which 13 arteries were detected by TCD simutaneously.4 BA were diagnosed by TCD but not proved by DSA. The sensitivity and the specificity of TCD in diagnosing BA spasm were 72.2% and 76.5% respectively.28 VA were diagnosed by DSA,among which 20 arteries were proved by TCD.6 VA were detected by TCD but not proved by DSA. The sensitivity and specificity of TCD in diagnosing VA spasm were 71.4% and 76.9% respectively.Conclusion TCD is reliable in diagnosing the spasm of MCA,BA and VA.

Objective To evaluate the effect of dexmedetomidine on the quality of recovery from sevoflurane-based anesthesia in the patients undergoing abdominal surgery.Methods Eighty patients of both sexes, aged 30-64 yr, weighing 45-80 kg, with American Society of Anesthesiologists physical status Ⅰ or Ⅱ , scheduled for elective abdominal surgery, were randomly assigned into 2 groups (n =40 each) using a random number table: control group (group C) and dexmedetomidine group (group D).After routine induction of anesthesia, all the patients were tracheally intubated, and mechanically ventilated.Anesthesia was maintained with sevoflurane inhalation and intermittent iv boluses of sufentanil and cisatracurium besylate, and bispectral index values were maintained at 45-60.After induction of anesthesia, dexmedetomidine was infused in a dose of 1 μg/kg over 15 min, followed by a continuous infusion of 0.6 μg · kg-1 · h-1 until 30 min before the end of surgery in group D.Group C received normal saline instead.Heart rate (HR) and mean arterial pressure (MAP) were recorded at the end of surgery, and at 1 min before and after extubation.The emergence time, extubation time, and occurrence of bucking during extubation, and nausea and vomiting, respiratory depression, and agitation during recovery from anesthesia were recorded.Results Compared with group C, MAP and HR were significantly decreased at 1 min before and after extubation, the emergence time and extubation time were shortened, the incidence of bucking, nausea and vomiting, and agitation was decreased, and no significant change was found in the incidence of respiratory depression in group D.Conclusion Dexmedetomidine infused in a dose of 1 μg/kg after routine induction of anesthesia, followed by a continuous infusion of 0.6 μg · kg-1 · h-1 until 30 min before the end of surgery, can significantly increase the quality of recovery from sevoflurane-based anesthesia in the patients undergoing abdominal surgery.

Objective To understand the immune regulatory function of monocyte-derived dendritic cells (MoDC) in patients with chronic severe hepatitis B (CSHB) and its roles in the severe illness progression of chronic hepatitis B (CHB) by detecting surface phenotype of MoDC and expression level of cytokines in MoDC after polyl : C treatment. Methods The peripheral blood mononuclear cells (PBMC) were isolated by Ficoll density gradient separation from 37 patients with CSHB, 20 patients with CHB, and 20 healthy controls (NC). Purified PBMC were acquired using immunomagnetic anti-CD14-beads. Then PBMC were induced to immature dendritic cell (iDC) in vitro. PolyI : C was added to induce DC maturation. The mean fluorescence intensity (MFI) of the phenotype marker molecules including HLA-DR, CD83, CD86 and CD80 on surface of iDC and mature DC (mDC) were detected by flow cytometry. The supernatants of MoDC culture were collected at 12,24 and 48 h after polyI : C treatment, respectively and the release levels of interleukin (IL)-12, IL-6and tumor necrosis factor (TNF)-α were determined by enzyme linked immunosorbent assay (ELISA). Comparisons among groups were done by single factor analysis of variance and homogeneity of variance was tested. Results There were no significant differences of phenotype marker molecules on cell surface of iDC, including HLA-DR, CD83, CD86 and CD80 in CSHB, CHB and NC groups.However, the expressions of HLA-DR, CD83, CD86 and CD80 on cell surface of mDC in CSHB group were lower than those in CHB and NC groups (F=59.73, 13.95, 34.80 and 73.02, respectively; all P＜0. 05). The secretions of IL-12 at three time points of 12 h, 24 h and 48 h after polyI : C treatment in group NC were higher than those in CHB and CSHB groups (F= 151.34, 126.65 and 72.76, respectively; P＜0.05), and peaked at 24 h which were (48.2±7.6), (56.7±11.8) and (97.8±16.2) ng/L, respectively. The secretions of IL-6 at the above three time points were CSHB＞CHB＞NC (F=92.50, 86.89 and 64.57, respectively; all P＜0. 05) and peaked at 12 h which were (1698.3±340.4), (965.8±231.7), (697.8±213.6) ng/L, respectively. The secretions of TNF-αat the above three time points were CSHB＞CHB＞NC (F=58.66, 122.36 and 44.73, respectively;all P＜0. 05) and were (19 672. 7±4214. 7), (9946. 1 ± 2586 5), (6659. 2±955. 8) ng/L,respectively at 24 h after treatment. Conclusions MoDCs of CSHB patients show mature defection and abnormal cytokine secretion. The expression level of IL-12 which mediates cellular immune is low.Meanwhile, the productions of IL-6 and TNF-α which mediate inflammatory response are up-regulated. This may be one of the major factors which lead to exacerbation of liver inflammation and ultimately development of severe hepatitis.

Objective To evaluate the safety,feasibility and results of the hand-assisted retroperitoneal laparoscopic living donor nephrectomy ( HRPLDN ) with a modified technique. Methods Living donors (n =32) were divided into HRPLDN group (n =16) and open group (n =16) according to surgical technique.Operative data and postoperative outcomes including operative time,estimated blood loss,warm ischemia time,length of hospital stay and complication rate,were collected. Results All procedures were completed successfully.In HRPLDN group,the mean operative time was 101.3 ± 21.2 min (range from 70 to 150 min),with an estimated blood loss of 53.8 ±25.5 ml (range from 20 to 100 ml) and warm ischemia time of 2.4 ± 0.6 min ( range from 1.5 to 3.5 min).No living donor needed conversion to open surgery and the urine volume of transplanted kidney after first 24 hours was 5036 ml (range from 3500 -6500 ml).The mean postoperative on bed time were (2.8 ± 0.7 ) d (ranging from 2 -4 d).All parameters of HRPLDN were significantly better than that of open groups. Conclusion Living donor nephrectomy with HRPLDN is a safe and reliable surgical technique.

Objective To assess the impact of intervention with Insulin therapy management unit program in the poorly controlled type 2 diabetic patients in a community of Shanghai.Methods There were 55 patients with type 2 diabetes with poorly controlled hyperglycemia (HbA1C ≥ 8％) enrolled in this study.They were divided at random into 2 groups:intensive care group and standard care group.The subjects in intensive care group were provided with a glucose meter and required to monitor their blood glucose levels at least 2 or 3 times per day.Community health provider acquired information of blood glucose level,episodes of hypoglycemia,and dosage of insulin every week by cell phone.Standard care patients received diabetes care from the same provider in outpatient clinic every month.Results By the end of 6 months of intervention,the intensive care group showed a significant difference in HbA1C as compared to the standard care group (7.40％ ±0.91％ vs 8.65 ％ ± 1.28％,P＜0.01).The frequency of self-monitoring of blood glucose (SMBG) was 4 times per month in both groups at baseline.After intervention,the frequency of SMBG in intensive care group was greatly increased compared to standard care group (50times per month vs 5 times per month,P＜0.01).The frequency of self-reported hypoglycemia in intensive care group was increased compared to standard care group (3 times per month vs once per month,P＜0.01).The average daily dose of insulin in intensive care group was increased 6 units by the end of the present study(P＞0.05).Conclusion After 6 months of intervention,the glycemic control was obviously improved in type 2 diabetic patients treated with insulin and the daily dose of insulin was not increased significantly.TheInsulin therapy management unit is effective and safe.

Objective To explore the characteristics of clinical symptoms and serum brain-derived neurotrophic factor(BDNF)level between depressive patients with and without attempted suicide behavior.Methods Serum BDNF level in depressive patients with(n=36)and without(n=55)attempted suicide behavior were assayed by ELISA,the severity of depression was measured by Hamilton rating scale for depression(HAMD).Results HAMD24 total scores(t=3.632,P=0.000),cognitive disturbance(t=-2.339,P=0.019)and hopelessness factor scores(t=-2.812,P=0.005)in depressive patients with attempted suicide behavior were significantly higher than those in depressive patients without attempted suicide behavior.There were no significant differences of anxiety/somatization,body weight,diurnal variation,psychomotric inhibition and sleeping disturbance fator scores between two groups(P＞0.05).The serum BDNF level in depressive patients with attempted suicide behavior was significantly lower than that in depressive patients without attempted suicide behavior(t=-2.122,P=0.037).There was no significant difference of serum BDNF level between male and female patients(P＞0.05).Conclusion There were certain characteristics on clinical symptoms of depressive patients with attempted suicide behavior.The low serum BDNF level might play an important role in the risk of suicide in depressive patients.
