Objective To investigate the in vitro effect of multi glycosidorum triptery (MGT) on cytokine production by splenocytes of oxazolone (OXZ) induced colitis in murine model. Methods Six mg of OXZ (in 50% of ethanol) was administered in male SJL/J mice intrarectally to induce colitis and mice were sacrificed 3 days later. Isolated splenocytes were cultured for 24 hours in the presence of PMA and ionomycin, MGT of 0.1 mg/ml or 0.01 mg/ml was added to the culture medium of splenocytes. Production of IFN ? and interleukin 4 (IL 4) in the supernatant was measured by ELISA. Results The production of IFN ? was suppressed by both 0.01 mg/ml and 0.1 mg/ml of MGT [normal control ( 1.24 ? 0.13 ) pg/ml→(0.97?0.26) pg/ml→(0.87?0.18) pg/ml, P

OBJECTIVETo evaluate the clinical effect and safety of dapoxetine in the treatment of premature ejaculation (PE).

METHODSWe randomly assigned 116 PE patients to receive dapoxetine on demand at 30 mg qd (dapoxetine group, n = 60, aged 23-49 years) or oral tamsulosin at 20 mg qd (control group, n = 56, aged 24-46 years). After 4 weeks of medication, we compared the clinical global impression of change (CGIC) , PE profile (PEP) scores, intravaginal ejaculation latency time (IELT) , and adverse reactions between the two groups of patients.

RESULTSCompared with the baseline, the IELT was remarkably prolonged after treatment both in the dapoxetine group ([0.86 ± 0.17] vs [4.32 ± 2.23] min, P < 0.05) and the control ([0.88 ± 0.15] vs [4.17 ± 2.26] min, P < 0.05), with no statistically significant difference between the two groups (P > 0. 05). The post-treatment rate of CGIC in the dapoxetine group had no statistically significant difference from that in the control (85.00% vs 82.14%, P > 0.05). In comparison with pre-treatment, the patients of both the dapoxetine and control groups showed dramatically improved scores after medication in perceived control over ejaculation (0.85 ± 0.23 vs 2.13 ± 0.97 and 0.88 ± 0.21 vs 2.06 ± 0.34, both P < 0.05), ejaculation-related personal distress (1.15 ± 0.64 vs 2.89 ± 0.26 and 1.19 ± 0.53 vs 2.82 ± 0.69, both P < 0.05), satisfaction with sexual intercourse (0.81 ± 0.33 vs 2.58 ± 0.37 and 0.79 ± 0.28 vs 2.45 ± 0.32, both P < 0.05), and ejaculation-related interpersonal difficulty (2.05 ± 0.61 vs 3.24 ± 0.35 and 2.03 ± 0.65 vs 3.18 ± 0.76, both P < 0.05), with no significant differences between the two groups (P > 0.05). The incidence of adverse reactions was significantly lower in the dapoxetine than in the control group (3.33% vs 30.36%, P < 0.05).

CONCLUSIONDapoxetine is effective for the treatment of PE, with its advantages of prolonging the intravaginal ejaculation latency time, improving the quality of sexual life, and low incidence of adverse reactions.

Objective: To investigate the influence of lidocaine on systemic inflammation in the perioperative ventricular septal defect (VSD). Methods: Twenty patients, scheduled for ventricular septal defect were randomly divided into 2 groups: lidocaine and control groups. Before rebeat lidocaine 1 mg/kg was given.The venous blood samples were obtained from the central venous at the following points: after induction of anesthesia and before cardiopulmonary bypass(CPB,T1),1 h after CPB(T2),2 h after CPB(T3), and 4 h after CPB(T4). IL-6 and IL-8 were determined by radio-immunoassay. Results: Compared with those at T1, the levels of white blood cells,polymorphonuclear neutrophils,IL-6 and IL-8 increased significantly from T2 to T4 in both groups. IL-6 and IL-8 levels reached the peak at T2. Compared with those in control groups, IL-6 level decreased obviously in lidocaine group from T2 to T4, but IL-8 level remained unchanged significantly. Conclusion: Under CPB and VSD repair the systemic inflammation is obvious, reaches the peak 30 min after CPB and persists to 4 h after CPB. Perioperative administration of lidocaine is effective against the inflammation.

Objective To evaluate transport efficiency and safety by process management during the handover of patients with tracheal intubation post-operation. Methods Prospective studies were performed between patients with or without process management during the handover. The time of handover were recorded and compared. The difference between systolic and diastolic blood pressure, heart rate, and arterial oxygen saturation were also recorded and compared. The adverse events during the handover were also investigated. Results It costed less time in the handover of patients under process management with significant difference[(4.75±0.54) min vs. (7.05±0.88) min, t=-17.21, P<0.01]. The incidence rate of harmful cases in the handover of patients under process management was significantly declined than that without process management[ 1.67%(1/60) vs. 13.33%(8/60),Χ2=4.324 3,P<0.05 ]. Conclusions Process management may facilitate the handover of patients with tracheal intubation post-operation and improve its safety.

Objective:To analyze the correlation factors between peripapillary duodenal diverticulum (PDD) and choledochectasia by CT scan.Methods:The clinical data of 220 patients with duodenal diverticulum detected by multi-slice spiral CT scan and confirmed by gastrointestinal angiography or endoscopic retrograde cholangiopancreatography (ERCP) in Dahua Hospital, Xuhui District of Shanghai City were retrospectively analyzed. The correlation of the PDD, the contact of common bile duct (CBD), length of contact and exudation with choledochectasia in patients with PDD were analyzed.Results:A total of 236 duodenal diverticulum were found in 220 patients. Among them, there were 152 PDD, 41 diverticulum located superior to the duodenal papilla, 28 diverticulum located inferior to the duodenal papilla, 3 diverticulum located lateral to the duodenal papilla, and 12 diverticulumlocated in the horizontal portion. The incidence of choledochectasia in patients with PDD contacted with CBD was significantly higher than that in patients with PDD not contacted with CBD: 59.35% (73/123) vs. 37.93% (11/29), and there was statistical difference ( P<0.05); the incidence of choledochectasia in patients with contact length of PDD and CBD ≥1.5 cm was significantly higher than that in patients without contact of PDD and CBD and patients with contact length of PDD and CBD <1.5 cm: 82.43% (61/74) vs. 24.49% (12/49) and 37.93% (11/29), and there was statistical difference ( P<0.05); the incidence of choledochectasia in PDD patients with exudation was significantly higher than that in PDD patients without exudation: 10/11 vs. 52.48% (74/141), and there was statistical difference ( P<0.05). Conclusions:The patients with contact length of PDD and CBD ≥1.5 cm and patients with PDD combined with exudation could be prone to choledochectasia.

Objective To explore the value of ultrasound-enhanced ultrasound (CEUS) in the differential diagnosis of orbital neoplasms by observing the perfusion characteristics of orbital benign and malignant neoplasms for the application of ultrasound contrast microbubbles.Methods Preoperative ultrasound imaging of 47 patients with orbital neoplasms(benign group 35 cases,malignant group 12 cases)were observed for the tumor characteristics of CEUS.The parameters of tumor imaging obtained time intensity curve (TIC) were obtained by quantitative analysis of SonoLiver analysis software,which were contrast agent arrive time (AT),rise time (RT),time to peak (TTP),mean transit time (mTT),area under the curve (AUC),maximum intensity(IMAX) and perfusion index (PI).Results Different characteristics of perfusion were shown between benign and malignant groups.Time parameters of TIC:rising slope,semidescending slope,IMAX,PI,mTT,semi-washed out time and RT were significantly different between the two groups (P ＜ 0.05) while there was no significant difference of parameters as AT,TTP,AUC.Conclusions There is certain clinical value of the CEUS in the differential diagnosis of ocular benign and malignant neoplasms.

Objective To establish and validate a standard method using flow cytometry (FCM)in human ABO blood group antibody (Ab) detection. Methods Sera samples from 52 blood donors were incubated with standardize red blood cells (RBCs), and anti-A/B antibody (IgM/IgG) was measured by indirect flow cytometry after adding secondary isotype-specific fluoresce labeled Ab. The results were compared with those by using ELISA reader. Results The changes of anti-A/B IgM measured by both methods correlated well and an overall correlation coefficiency of 0.730 for IgM was obtained by Spearman's rank testing (P＜0.05). FCM showed better specificity, sensitivity and reproducibility over ELISA reader. In blood group A samples (n = 16) or B samples (n = 16) ,the antirespectively. IgG blood group Ab could only be detected in blood group O sera. Conclusion Compared with traditional methods,FCM is a more objective method to offer accurate detection of natural ABO blood group Ab (IgM/IgG) and allowed semi-quantitative measurement of antibody levels.

Objective To investigate the effects of the overexpression of HO-1 induced by CoPP in the donor on the survival of transplanted allogeneic islets of rats and the mechanism.Methods (1) Brown Norway rats were randomly divided into control group, and CoPP-induced group receiving intraperitoneal injection of CoPP (2.5 mg/kg) at 3rd and 1st day prior to islet isolation.By using the cytoimmunofluorescenee and Western blot, the expression of HO-1 in isolated islets was detected.The insulin level in the supernatant of the cultured islets stimulated with glucose was determined by ELISA.(2) Lewis male rat diabetic models were established by a single intravenous injection of alloxan, and then randomly divided into CoPP group and control group.Islets were transplanted under the left kidney capsule of each diabetic recipient.The survival time after transplantation, and pathological changes following rejection of the islet grafts were analyzed.Results The HO-1 was highly expressed in the islets isolated from CoPP-treated rats by cytoimmunofluorescence and Western blot.After stimulation with 16.7 mmol/L glucose, the insulin concentration in Copp-treated and Copp-untreated groups was (46.60± 1.13) and (19.01 ± 1.49) mIU/L respectively (P<0.05).The insulin concentration in Copp-treated and Copp-untreated groups in islets stimulated with 5.6 mmol/L glucose was (15.65 ± 0.89) and (12.28 ± 0.89) mU/L respectively (P>0.05).The stimulated index in Copp-treated and Copp-untreated groups was (2.98 ± 0.10) and 1.55 + 0.01 respectively (P< 0.05).The survival time of islets allograft in Copp-treated and Copp-untreated groups was separately (12.20±5.67) and (5.60± 1.14) days respectively (P<0.05).Histological analysis revealed the presence of more islands of insulin-positive cells and considerably fewer lymphocytes or inflammatory infiltration than the controls.Conclusions CoPP could induce the HO-1 expression of islets, and improve their function.Over-expression of HO-1 in islets could prolong survival time of islets allograft.

OBJECTIVETo explore the clinical effects of transforaminal endoscopic spine system in surgical revision of lumbar vertebrae.

METHODSFrom January 2012 to October 2013,14 patients who needed reoperations of lumbar vertebrae were treated using transforaminal endoscopic spine system (TESSYS). There were 8 males and 6 males, aged from 27 to 84 years old with an average of (50.4 ± 18.9) years. Visual analogue scale (VAS) and Japanese Orthopaedic Association Scores (JOA) were compared before and after surgical revision. Macnab standard was used to assess the clinical effect.

RESULTSAll the patients were followed up from 6 to 27 months with the mean of 18 months. Preoperative VAS score was 6.79 ± 1.31, and in a week,3 months and 6 months after operation were 2.50 ± 1.29, 2.21 ± 1.53, 1.64 ± 1.08, respectively, which were all much lower (P < 0.01) than preoperative score. Preoperative JOA score was 12.43 ± 1.95, and the above corresponding postoperative JOA scores were 21.50 ± 3.78, 21.93 ± 4.55, 23.36 ± 4.33, respectively, which were all much higher than preoperative score (P < 0.01). According to the modified Macnab criteria, 5 patients got an excellent results, 7 good, 1 fair and 1 poor. The nerve root injury of L5 occurred in 1 case during paracentesis and no other complications were found.

CONCLUSIONSelecting the appropriate indications using TESSYS in surgical revision of lumbar vertebrae can successfully avoid the operation scar, reduce the surgical complications and obtain satisfactory clinical outcomes.
