Objective:This study aims to evaluate the effect of an elevated preoperative neutrophil to lymphocyte ratio (NLR) on outcome after comprehensive staging laparotomy or optimal tumor debulking surgery for epithelial ovarian cancer (EOC) and determine the value of the NLR as an independent prognostic prediction marker. Methods:A total of 80 women with primary EOC and with complete clinical and pathological information documented at the time of surgery were selected for this study. The optimum cut-off value of the preoperative NLR was identified through receiver operator characteristic (ROC) curve, and the patients were then classified into two groups: low and high NLR group. Univariate and multivariate analyses were performed to assess the prognostic effect of the preoperative NLR patients who underwent comprehensive staging laparotomy or optimal tumor debulking surgery. The levels of expression of CD68 were measured through immunohistochemistry. Results:The optimal cut-off value of the NLR was 3.8. The preoperative NLR differed significantly in the FIGO stage between the low NLR group (NLR ≤3.8) and the high NLR group (NLR>3.8), but no discrimination was observed in other parameters. The mean follow-up time was 45 months, and the post-operative 1-and 3-year survival rates were 93.7%and 60.0%, respectively. The preoperative NLR>3.8 and stageⅢ/Ⅳwere all risk factors for poor overall and disease-free survival. Multivariate analysis revealed the patients with high NLR (P<0.05) and stage Ⅲ/Ⅳ (P<0.05) had prognostic significance for poor overall survival. The number of CD68-positive tumor-associated macrophages was significantly higher in the high NLR group than in the low NLR group (54.65 ± 8.78 and 41.78 ± 9.10, respectively; P<0.001). Conclusion: An elevated blood preoperative NLR indicates poor prognosis in patients with EOC. Preoperative NLR may function as an important independent prognostic factor for patients with EOC.

Objective To explore the effect of ginseng combined with transplantation of bone marrow mesenchymal stem cells(BMSCs)on functional recovery of rats with spinal cord injury(SCI). Methods Forty-eight female Wistar rats were randomly assigned to following four groups(n=12 per group):the sham operation group was treated by opening the vertebral lamina and exposing spinal cord without SCI;the SCI model group was reproduced by using improved Allen bump method and afterwards no treatment was given;methyl prednisolone(MP)group was treated by MP pulse treatment after SCI,including intravenous injection of MP 30 mg/kg immediately after SCI and 4 hours later the same injection was repeated,and then the same intravenous injection 2 times daily,3 days in total;The ginseng+BMSCs group was treated by orally taking ginseng ultra-microgranules 300 mg/kg after SCI,twice a day for 20 days and BMSCs 5μL(concentration 1×107 cell/μL)transplantation was carried out in SCI region on the 7th day after SCI. In the above 4 groups,the ethological observation(BBB scores)was done regularly and on the 30th day after operation,silver staining was applied to investigate the changes of spinal cord,and neuro-electrophysiological tests including somatosensory evoked potential(SEP)and motor evoked potential(MEP)were performed. Results In sham operation group,after surgery the movement of both hind limbs became temporarily sluggish and on the 7th day their functions recovered to approximately normal. In SCI model group,after injury paralysis of both hind limbs occurred,while in the MP group and ginseng+BMSCs group,different degrees of functional recovery of the injured limbs developed,and the recovery in ginseng + BMSCs group was more significant. Compared with sham operation group,after surgery the BBB score was reduced markedly at various time points in SCI model group;compared to the SCI model group,the BBB scores in MP and ginseng+BMSCs groups were increased significantly,especially more remarkable in ginseng+BMSCs group(all P<0.05),and beginning from the 12th day after operation,the difference became obvious (5.23±1.22 vs. 3.61±1.03, P<0.05). Histological detection showed that in sham operation group,the structure of spinal cord was complete,neurons distributed evenly in the gray matter and a large number of silver staining positive nerve fibers paralleled to each other and arranged regularly;in SCI model group,fragmented construction was present and the defects of gray and white matters were prominent. Compared with the SCI model group, the extents of tissue necrosis in MP and ginseng + BMSCs groups were ameliorated. The neuro-electrophysiological tests demonstrated that in SCI model group,the loss of normal wave form occurred. Compared with SCI model group,in MP and ginseng+BMSCs groups,after treatment latent periods(ms)were shortened prominently in different degrees of SEP and MEP,and their peak-to-peak values(mV)were increased obviously;the improvement in potential in ginseng+BMSCs group was greater than that in MP group〔SEP:latent period(ms):3.31±0.36 vs. 4.66±0.33, peak-to-peak value(mV):0.10±0.01 vs. 0.05±0.01,MEP:latent period(ms):3.40±0.13 vs. 4.24±0.31, peak-to-peak value(mV):41.12±0.56 vs. 16.46±2.83,all P<0.05〕. Conclusion A combined treatment of ginseng and BMSCs transplantation can effectively promote the recovery of neural function for rats with SCI.

Objectives To determine the significance of serum total bile acid (TBA) in the diagnosis and treatment of infantile hepatitis syndrome. Methods Serum TBA and other liver function related items were determined with automatic enzymatic assay techniques in 67 with infantile hepatitis syndrome patients (age 26 days～7 months) and 100 normal infants (age 20 days～1 year). Results In the control group, the serum TAB level was 0～11.3 ?mol/L. TBA level was abnormal in 89.5% patients and the values were 0.5～226.0 ?mol/L ?s =(79 5?54.3) ?mol/L]. The difference was significant between the two groups. The TBA levels were well related to those of ALP, DBIL and ? GT and TBA was better than others in sensitivity and specificity. . The difference was significant between the two groups. The TBA levels were well related to those of ALP, DBIL and ? GT and TBA was better than others in sensitivity and specificity. Conclusion Serum TBA level is important in evaluating the diagnosis, treatment, and prognosis of infantile hepatitis syndrome.

Objective To investigate the clinical application value of Quadrant system combined with percutaneous pedicle screw fixation for treatment of lumbar degenerative disease.Methods The clinical data of 40 patients who sufferred from lumbar degenerative disease,were randomly divided into two groups:Quadrant system combined with percutaneous pedicle screw fixation to do discectomy and intervertebral bone graft fusion as invasive group (n =20),traditional posterior lumbar interbody fusion as conventional group (n =20).The operation time,length of incision,blood loss,postoperative drainage,JOA score of preoperation and postoperation,and effect (reforming Macnab standard) between two groups were recorded and compared.Results Operations were all well done in two groups.The operation time in invasive group was longer than that in traditional group [(147.3 ± 8.9) min,(136.7 ± 10.2) min,t =3.5,P ＜ 0.05].The length of incision [(3.65 ± 0.68) cm,(1 1.11 ± 1.29) cm,t =22.88,P ＜ 0.05)],blood loss [(205.00 ± 63.04) mL,(270.50 ± 77.58) mL,t =2.93,P ＜ 0.05],postoperative drainage [(90.3 ± 10.8) mL,(180.6 ± 1 3.9) mL,t =22.96,P ＜ 0.05] and days in hospital [(16.9 ± 2.0) days,(18.9 ± 2.1)days,t =3.05,P ＜ 0.05] in invasive group were all less.than those in traditional group (P ＜ 0.05).All cases had been followed up for 6-18 months,average of 13 months.There were no significant differences in excellent and good rate (reforming Macnab standard) between two groups in the last following up (P ＞ 0.05).There were no significant differences of JOA scores in preoperation [(12.0 ± 1.7) points,(11.0 ± 1.5) points,P ＞ 0.05],postoperative half a year [(22.0 ± 2.3) points,(21.0 ± 2.5) points,P ＞ 0.05],and postoperative one year [(23.0 ± 1.9) points,(22.0 ± 2.0) points,P ＞ 0.05].Conclusion Quadrant system combined withpercutaneous pedicle screw fixation is a safe,effective and minimally invasive surgical technique in treating lumbar degenerative disease.Compared with conventional group,invasive group has advantages such as less injury,less blood loss,simple operation,and good curative effect,which should be popularized.

Purpose:To study whether immune factors are involved in the occurrence of immune thrombocytopenia in some malignancy. Methods:Platelet associated antibodies and immune function were examined in 30 cases of malignancy with thrombocytopenia in our hospital. Results:Platelet associated antibodies(pAIgG,pAIgA,pAIgM)increased significantly in 11 of 30 patients with malignancy,especially those with metastatic adenocarcinoma and in the middle or advanced stage. Bleeding is common in these patients. After being treated with corticosteroid, immunosuppressive drugs or immunoglobulin,the platelet count of the patients increased and the bleeding syndrome improved. Conclusions:Thrombocytopenia in malignancy is partly due to the abnormal immune reaction of the patients.

Objective · To investigate antiemetic effect of aprepitant for moderately chemotherapy-induced nausea and vomiting in patients with gastrointestinal cancer. Methods · From 2014 July to 2015 August, 130 cases of gastrointestinal cancer patients were collected in Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine, who received moderate emetogenic risk of chemotherapy for at least four courses. One hundred and nine patients were treated with aprepitant, palonosetron and dexamethasone on day 1, and aprepitant and dexamethasone on day 2 and 3. Twenty-one patients only received aprepitant and dexamethasone on day 1 and dexamethasone on day 2 and 3 in the first course of chemotherapy. During subsequent courses of chemotherapy they received aprepitant and treated in the same way as 109 patients. MASCC antiemetic tool (MAT) was used to evaluate the intensity of nausea. The primary endpoint was complete response (CR, no emesis and use of no rescue antiemetics) during the overall study phase (0-120 h after chemotherapy) at the second course. The secondary endpoint was complete protection (CP, CR plus no significant nausea) during the overall, acute (0-24 h), and delayed (24-120 h) phases at the second course. Results · The CR rates were 90.0%, 94.6% and 90.8% of patients in the overall, acute and delayed phases, respectively. The corresponding CP rates were 83.8%, 87.8% and 84.6 %, respectively. The CR rate increased from 42.9% to 57.1% during acute phase and increased from 9.5% to 90.5% during delayed phase for 21 patients after treatment with aprepitant. The main adverse reactions include constipation, anorexia and hiccups. Conclusion · Aprepitant combined with palonosetron and dexamethasone can effectively prevent moderately chemotherapy-induced nausea and vomiting in patients with gastrointestinal cancer. Aprepitant therapy can effectively maintain antiemetic effect in patients with many chemotherapy courses.

Objective To investigate the CT and MRI features of ovarian fibroma.Methods CT and MRI findings of 42 patients with ovarian fibroma confirmed by operation and pathology were analyzed retrospectively.Twenty-one patients were examined by CT,26 cases was examined by MRI,and 5 cases were examined by CT and MRI.Results In 42 cases of ovarian fibroma,there were simple type in 29 cases,degenerative type in 11 cases,and special type in 2 cases.All the cases had single lesion,morphology were round or elliptic or lobulated,clear boundary in 40 cases,partial fuzzy boundary in 2 cases,3 cases with calcification,hemorrhage in 1 case.The maximum tumor diameter were 1.4-26.7 cm,median value was 5.5 cm.Simple type of ovarian fibroma were equal density on CT,low signal on T1WI and T2WI.Degeneration type was patchy,fissure,low density areas on CT or high signal on T2WI,and the tumor parenchyma was almost no enhancement or only slight enhancement.A large number of hemorrhages had been found in 1 special type patient,and significantly enhanced in the other special type patient.Special type were misdiagnosed as malignant tumor.Conclusion CT and MRI performance of ovarian fibroma has some characteristics,but diagnosis still need to rely on pathology.

Objective To investigate the changes in skin microcirculatory perfusion during induction of general anesthesia and the effects oftwo fluid therapy regimens in patients undergoing abdominal surgery.Methods Thirty-six ASA Ⅰ or Ⅱ patients aged 18-64 yr scheduled for elective major abdominal surgery were randomized to receive either 6% hydroxyetlayl starch(130/0.4)7 ml/kg(HES group,n=18)or lactated Ringer's solution 7 ml/kg(RL group,n=18)for compensatory intravascular volultne expansion(CVE)before tracheal intubation.Meanwhile both groups received continuous intravenous infusion of RL at a of 8 ml·kg~(-1)·h~(-1).Tracheal intubation was performed at 40 min after the onset of infusion.Anesthesia was maintained with with sevoflurane,remifentanil and rocuronium.Operation was started at 20 min after tracheal intubation.The microcirculatory perfusion was measured on forehead skin by using Doppler perfusion imaging system(LDPI)PI)at the onset of fluid infusion(T_0,baseline),the end of endotracheal intubation(T_1)and the onset of skin incision(T_2).Rwsults The MAP,HR,blood gases and body temperature were within the normal during the experiment and there was no significant difference between the 2 groups.The skin microcirculatory perfusion and CVP at T_1 were significantly higher in group HES than in group RL(P<0.05 or 0.01).Compared with the baseline value at T_0,the skin microcirculatory perfusion at T_1 was significantly increased in group HES(P<0.01),but there was no significant change in the skin microcirculatory perfusion at T_1 in group RL(P>0.05),the skin microcirculatory perfusion at T_2 was singificantly decreased in both groups(P<0.01),and CVP and PaO_2/FiO_2 at T_(1.2) were significantly increased,while Hb at T_(1.2) was significantly decreased in both groups(P<0.05).The skin microcirculatory perfusion in both groups was significantly lower at T_2 than at T_1(P<0.01).Conclusion The infusion of 6% HES 130/0.4 can improve the skin microcirculatory perfusion and the effect is better than that of RL during induction of general anesthesia in patients seheduled for abdominal surgery.

Objective To determine the potential impact of superantigens produced by skin-colonizing Staphyiococcus aureus in patients with atopic dermatitis and eczema. Methods Of 117 patients with atopic dermatitis and 199 with eczema, 140 Staphyiococcus aureus strains were isolated from the skin specimens. Superantigens were detected with reverse passive latex agglutination. Results Among 140 Staphyiococcus aureus strains, 60 (42.9%) produced superantigens, among which 43 produced one kind of superantigens only and 17 produced at least two kinds. Of strains isolated from atopic dermatitis, 51.5% produced superantigens and no significant difference was seen in superantigen production between lesional and non-lesional strains in atopic dermatitis. Of strains isolated from eczema patients, 34.7% (all were lesional strains) produced superantigens. The positive rates of total superantigens, lesional superantigens and toxic shock syndrome toxin-1 production were all higher in the strains from atopic dermatitis than in those from eczema. Conclusions Superantigen production by skin-colonizing Staphyiococcus aureus probably plays a more important role in atopic dermatitis than that in eczema. However, further studies are necessary to validate its importance.

Objective To evaluate the effect of methylprednisolone on hepatic ischemia-reperfusion (I/R) injury in the patients undergoing hepatolobectomy.Methods Sixty ASA physical status Ⅱ or Ⅲ patients,aged 30-64 yr,weighing 45-75 kg,scheduled for elective hepatolobectomy,were randomized to control group or methylprednisolone group (n =30 each).After induction of anesthesia,methylprednisolone 500 mg (in 100 ml of normal saline) was infused intravenously at 5 ml/min before skin incision in group M.Anesthesia was induced with propofol,fentanyl and cisatracurium.The patients were endotracheally intubated and mechanically ventilated.PETCO2 was maintained at 35-45 mmHg.Anesthesia was maintained with 1％-3％ sevoflurane inhalation,remifentanil infusion,and intermittent iv boluses of fentanyl and cisatracurium.MAP was maintained at 70-100 mmHg and HR at 50-90 bpm.At 10 min before induction of anesthesia,and on postoperative day 1,3 and 5,venous blood samples were collected for determination of the plasma levels of alanine aminotransferase (ALT),aspartate amminotransferase (AST),total bilirubin (TBIL),tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6).Results Compared with group C,the plasma levels of ALT,AST and TBIL were significantly decreased on postoperative day l and 3,and the plasma concentrations of TNF-α and IL-6 were decreased on postoperative day 1,3 and 5 in group M.Conclusion Methylprednisolone can reduce hepatic I/R injury in the patients undergoing hepatolobectomy and inhibition of systemic inflammatory responses is involved in the mechanism.
