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 quality of life(QOL)of postpartum women within six months after delivery in Pudong New Area in Shanghai.Methods From January 1st to June 30th in 2011,435 postpartum women,discharged from Children and Women's Health Care Hospital in Pudong New Area,Gaoqiao Community Health Service Center and Lujiazui Community Health Service Center in Pudong New Area,were investigated by SF 36 questionaire including eight items [physical functioning (PF),role limitations due to physical problems (RP),bodily pain (BP),general health (GH),vitality (VT),social functioning (SF),role limitations due to emotional problems (RE) and mental health (MH)] and divided into three subgroups according to the duration after delivery (8-42,43-119 and 120 180 d).The SF-36 scores were compared with the control (baseline data of 25 to 36-year-old young women in Pudong New Area) or within the three groups.Statistical methods,such as t-test and analysis of variance,were applied.Results (1) The tota lscore and the scores of the seven items in SF-36 were lower than those of control (total score:74.2±11.7 vs 80.5,PF:79.0±19.0 vs 94.6,RP:47.5±12.2 vs 85.7,BP:74.0±18.7 vs 78.4,GH:73.9±13.1 vs 71.0,VT:69.8±16.2 vs 75.0,SF:78.3±20.1 vs 86.9,RE:63.4±21.7 vs 83.5,t=-11.225,-17.105,-18.914,-4.893,3.688,-6.642,-8.881 and-10.076,all P＜0.05) and no significant difference was found in MH score between the postpartum women and the control (78.3±15.0 vs 77.8,t=0.629,P＞0.05).Compared the SF-36 scores in three subgroups (8 42,43-119 and 120 180 d postpartum),the differences on PF score(73.0±19.1,86.3± 17.1,89.1±12.9),RP score(32.4±18.6,57.7±19.1,79.9±12.0),BP score(70.7±18.0,75.6±19.0,81.6±17.3),SF score(76.3±19.6,78.2±21.7,83.9±19.3),RE score(58.5±12.9,71.4± 18.3,70.1± 19.5) and SF-36 total score (72.2± 11.1,76.1± 12.8,78.0± 11.1) were all significant (F=37.744,60.640,13.137,5.185,4.577 and 10.548,allP＜0.05).The PF,VT,RE and total score of postpartum women at 120-180 days after delivery were still lower than those of the control group(t=-4.174,-2.353,-3.341 and-2.166,all P＜0.05).Conclusions The QOL of postpartum women within six months after delivery is not good enough.Up to 120-180 days after delivery,the QOL remains.More efforts should be made to improve the QOL of postpartum women by the whole society.

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.

Objective To explore the inhibitory effect of Oldenlandia diffusa extract on colorectal cancer angiogenesis in BALB/c mice. Methods Thirty-two BALB/c mice with subcutaneous CT26 colon cancer animal model were randomly equally divided into four groups,including the control group (groupⅠ,saline 0.1 mL/(10. d), O. diffusa ethanol extract of 90 mg/(kg.d) (groupⅡ), O. diffusa ethanol extract of 180 mg/(kg.d) (groupⅢ) and O. diffusa ethanol extract of 360 mg/(kg.d) (group Ⅳ) . Each group of mice were treated with intragastric administration of law administration 12 days after vaccination, then stopped and continue fed to 32 days, and the mice were killed. Micro-vascular dense ( MVD) was observed and countered under the microscopy by immunohistory chemistry. Results The murine colon tumor volumes of GroupⅡ,ⅢandⅣwere significantly less than that of groupⅠ,with significant difference ( <0.05) . The tumor microvessel density values of four groups was (7.83±2.87), (5.32±1.27), (1.77±0.70) and (1.87±0.68),respectively. The number of tumor blood vessels in GroupⅡ,Ⅲ and Ⅳ were significantly less than that of Ⅰ group, with significant difference ( <0.05) . Conclusion Within a certain dose range, the ethanol extract of O. diffusa can significantly inhibit the mouse colon cancer and the mechanism may be realated to inhibiting tumor angiogenesis.
