Objective To investigate the clinical value of classic intrafascial supracervical hysterectomy(CISH) by including the clipping of the uterine artery.Methods A total of 60 cases of benign uterine diseases were included in the study.After the uterine artery had been dissected and clipped on both sides under laparoscope,classic intrafascial supracervical hysterectomy was performed.Results All the operations were performed successfully under laparoscope.No conversions to open surgery were needed.Operating complications happened in no case.The operating time was 72~186 min(91.4?26.3 min),the amount of blood loss was 50~150 ml(76.5?20.6 ml),the time to postoperative gastrointestinal function recovery was 18~30 h(22.7?5.8 h),and the volume of pelvic drainage within 24 hours,50~160 ml(80.5?31.8) ml.Postoperative body temperature was elevated to 38.5 ℃ in 2 cases,the postoperative pyrexia rate being 3.3%.The length of postoperative hospital stay was 4~7 d.Follow-up for 6~18 months(10.6?4.2 months) in the 60 cases showed 3 cases of small amount of vaginal bleeding at 1~3 months,which were cured with the use of antibiotics and hemostatics for 5~7 d.Conclusions Classic intrafascial supracervical hysterectomy by including the clipping of the uterine artery is a safe and effective improvement to CISH technique.

Objective To investigate the clinical efficacy of total laparoscopic hysterectomy(TLH) with separating and blocking uterine arteries.Methods From January 2004 to June 2006,68 cases of uterine benign diseases underwent TLH by blocking uterine arteries after separating and clipping uterine arteries with Titanic clip.Results All operations were performed successfully without conversion to open surgery and complications.1 patient,who had twice gastrohysterectomy histories,underwent bipolar coagulating uterine arteries as to the failure of separating bilateral uterine arteries.Pelvic adhesion release was performed in 18 cases,unilateral or bilateral adnexectomy in 14 cases,oophorocystectomy in 8 cases,appendectomy in 1 case,and cholecystectomy in 1 case simultaneously.The operation time was 90-185 min,(112.6?27.5)min.The time of separating uterine artery in one side was 3-15 min,(5.2?3.4)min.The intraoperative blood loss was 50-150 ml,(86.5?39.6)ml.The time to first bowel movement was 18-48 h,(27.3?4.8)h.The rate of postoperative pyrexia was 4.4%(3/68),and the hospital stay was 4-7 d,(5.1?1.8) d.A follow-up period of 2-6 months,(3.5?1.6) months,showed 3 cases of vaginal dropping hemorrhage 1-2 months after operation,which was cured with the use of antibiotics and hemostatics for 5-7 d.Conclusions TLH with separating and blocking uterine arteries is a safe,effective and feasible procedure with less complication,so it is worthy of being recommended.

Objective To evaluate the clinical significance of the serum β2-microglobulin (β 2-MG) and lactic dehydrogenase (LDH) in multiple myeloma (MM) patients.Methods The serum levels of β2-MG and LDH in 63 MM patients (MM group) and 20 healthy person (control group) were measured by biochemical assay.Results The serum levels of β 2-MG and LDH in MM group were higher than those in control group[(3.81 ± 0.62) mg/L vs.(2.43 ± 0.91) mg/L and (296.4 ± 34.7) U/L vs.(145.5 ±17.8) U/L,P ＜ 0.05].Furthermore,the serum levels of β 2-MG and LDH increased gradually with MM clinical staging (P ＜0.05).After VAD chemotherapy,the serum levels of β 2-MG and LDH in clinical response MM patients(54 cases) were significantly decreased [(2.51 ± 1.36) mg/L vs.(3.57 ± 0.82) mg/L and (159.1 ± 35.2) U/L vs.(285.3 ± 87.6) U/L,P ＜ 0.05],while those in no response patients (9 cases)were unchanged (P＞ 0.05).Conclusion The serum levels of β 2-MG and LDH can be taken as a clinical index to classify the clinical phase,prognosis and effectiveness of chemotherapy in MM patients.

The effects of arginine vasopressin (AVP) on the contents of ir-?-EP and ir-Dyn A1-13 in ischemic brain regions of Mongolian gerbils were observed with radioimmunoassay in this study.The results showed that the contents of ir-?-EP were significantly increased and those of ir-Dyn A1-13 were decreased in ischemic cortex and hypothalamus after injection of AVP into the lateral ventricle. However, the contents of ir-?- EP were markedly decreased and those of ir-Dyn A1-13 were unchanged significantly in the ischemic cortex and hypothalamus after intraventricular infusion of AVP antiserum.

The purpose of this experiment was to study the role of arginine vasopressin (AW) in acute cerebral ischemic edema in mongolian gerbils. The results showed that intracerebroventricular injection (ICV) of AVP exacerbated the ischemic brain edema, while ICV of AW antiserum significantly decreased the ischemic brain edema. Nimodipine couldn't block this role of AW in ischemic brain edema. The cortical Na+ -K+ ATPase activity was significantly decreased, the contents of cAMP in the ischemic cortex and hypothalamus and the contents of cGMP in the hypothalamus were remarkably increased after ICV of AW. These suggest AW was involved in the pathophysiologic process of acute ischemic brain edema. And its mechanism might be the effect of AW on AW receptor mediated by cAMP, cGMP, and that in turn inhibited the Na+ -K+ ATPase activity of brain cell membrane, then exaggerated the formation of ischemic brain edema.

Objective:To validate the predictive function of Field Assessment Stroke Triage for Emergency Destination (FAST-ED) score on large vessel occlusion (LVO) in Chinese population.Methods:The information about the patients who had the disease onset within 24 hours, were treated in the Emergency Department of Jinling Hospital, and diagnosed as ‘acute ischemic stroke’ was collected. Via the emergent brain computed tomography angiography or digital subtraction angiography, the patients were divided into LVO group and non-LVO group. The scores of FAST-ED were calculated according to the National Institutes of Health Stroke Scale (NIHSS) scores and compared with Rapid Arterial oCclusion Evaluation (RACE), 3-item Stroke Scale (3I-SS), Cincinnati Stroke Triage Assessment Tool (C-STAT), and Prehospital Acute Stroke Scale (PASS) scores. Moreover, the patients were further divided into anterior and posterior circulation lesion groups to explore whether the FAST-ED scale can differ the anterior or posterior circulation effectively.Results:Three hundred and eighty-one patients were eventually included, among whom 284 were diagnosed as LVO, and 97 were diagnosed as non-LVO. Receiver operating characteristic curves showed that cut-off value of 4 optimized the scale (sensitivity: 0.76, specificity: 0.69, area under the curve: 0.78). The area under the curve of FAST-ED score(0.78) showed no statistically significant difference with NIHSS (0.79), RACE (0.77), 3I-SS (0.78) and C-STAT scores (0.75), and exhibited statistically significant difference with PASS score (0.74; 95% CI 0.69-0.78, P=0.01). FAST-ED score showed no statistically significant difference in predicting anterior and posterior circulation lesions. Conclusions:FAST-ED score can predict LVO in a rather accurate manner. It can predict anterior and posterior circulation lesions with similar effectiveness. So FAST-ED is able to be a prehospital screening tool and make assistance to the prehospital treatment.

Objective To investigate the risk factors for early neurological deterioration (END) in patients with acute middle cerebral artery infarction.Methods From January 2009 to December 2012,81 patients with acute middle cerebral artery infarction completed cerebral angiography admitted to the Department of Neurology,Nanjing General Hospital of Nanjing Military Command were enrolled retrospectively.END was defined as that the National Institutes of Health Stroke Scale (NIHSS) score increased ≥2 or the motor score increased ≥ 1 with in 72 h after admission compared with the baseline score on admission.All the patients were divided into either an END group (26 cases) or a non-END group (55 cases) according to whether the occurrence of END.Univariate factor analysis was used to analyze the differences of the clinical data between the two groups.The grade standard of collateral circulation was assessment with the collateral circulation assessment system of the American Society of Interventional and Therapeutic Neuroradiology/Sociey of Interventional Radiology.Multivariable Logistic regression analysis was used to analyze the risk factors for END after acute middle cerebral artery infarction.Results Compared with the patients in the non-END group,the proportions of age 60 years (65.4％ [17/26] vs.36.4％ [20/55];x2 =5.992,P =0.014),high-sensitivity C-reactive protein level ≥4.0 mg/L (76.9％ [20/26] vs.45.5％ [25/55];x2 =7.080,P =0.008) and diabetes (38.5％ [10/26] vs.16.4％ [9/55],x2 =4.802,P =0.028) in the END group were increased significantly,while the collateral circulation grade was decreased significantly (Z =-3.253,P ＜ 0.01).Multivariable Logistic regression analysis showed that the age ≥60 years (OR,3.412,95 ％ CI 1.075-10.824;P =0.037),high-sensitivity C-reactive protein level ≥ 4.0 mg/L (OR,3.812,95％ CI 1.141-12.740;P =0.030),and collateral circulation grade (OR,2.165,95％ CI 1.241-5.514;P =0.009) were the independent risk factor for END in acute middle cerebral artery infarction.Conclusion The decreased collateral circulation level,age ≥ 60 years and high-sensitivity C-reactive protein≥4.0 mg/L were the independent risk factors for occurring END in acute middle cerebral artery infarction.

Objective:To investigate the characteristics of attention bias in Wilson disease(WD) patients with different levels of state-trait anxiety.Methods:The emotional Stroop paradigm and the state-trait anxiety inventory(STAI) were used to evaluate the anxiety level and the characteristics of attention bias in 49 inpatients with WD.SPSS 25.0 software was used for statistical analysis.Independent sample t-test was used for comparison between the two groups.Multiple linear regression analysis was used to evaluated the influencing factors of attentional bias response time. Results:(1) In WD patients, the response times measured under the positive, negative and neutral words in the high trait anxiety group((867.0±172.1)ms, (877.0±167.7)ms, (898.4±169.8)ms, respectively) were significantly higher than the low trait anxiety group((771.9±128.9)ms, (770.9±110.4)ms, (778.4±120.1)ms, respectively) and the differences were statistically significant( t=-2.183, -2.605, -2.847, all P<0.05). The response times under the positive, negative and neutral word measured in the high state anxiety group((866.9±171.9)ms, (867.8±173.8)ms, (889.8±173.5)ms, respectively) were higher than those of the low state anxiety group((771.9±129.2)ms, (780.4±109.3)ms, (787.3±123.0)ms, respectively) and the differences were statistically significant( t=-2.177, -2.116, -2.378, all P<0.05). (2) Multiple linear regression analysis showed that the total score of trait anxiety ( B=4.584, 4.671, 5.376, P=0.020, 0.015, 0.008) and age ( B=9.314, 7.864, 7.505, P=0.002, 0.008, 0.014) were the influencing factors of response times measured under the positive, negative and neutral emotion words. Conclusion:Anxiety will lead patients with WD to show more negative attention bias, and trait anxiety can significantly predict the characteristics of attention bias.

A rapid determination of methamphetamine, amphetamine, 6-monoacetylmorphine, and morphine in hair samples by UPLC-MS/MS was established and optimized.The concentration of target compounds in the hair of drug abusers and drug laboratory technicians was investigated and the cut-off value was evaluated.After cleaned hair was extracted by grinding with methanol-water (7∶3) at 3 000 r/min for 100 s, the final solution after adjusting the volume to methanol-water (1∶1) was analyzed by UPLC-MS/MS.The analytes were gradient eluted on a Waters Acquity BEH C18 (2.1 mm × 100 mm, 1.7 μm) column with 5 mmol/L ammonium formate-0.1% formic acid aqueous solution and acetonitrile as mobile phase at a flow rate of 0.4 mL/min. The ESI+ ion source and multiple reaction monitoring (MRM) were used to select the qualitative and quantitative ion pairs of the four target compounds. All analytes showed good linearity (R2 ≥ 0.999 6) in the range of 0.01-5 ng/mg (except amphetamine in 0.01-4 ng/mg), limit of the quantitation was 0.01 ng/mg, and the limit of detection was 0.001-0.008 ng/mg.The accuracy, precision, matrix effect, and recovery all met the requirements of biological sample methodology.According to the comprehensive consideration of the receiver operating characteristic (ROC) curve, Youden index, law enforcement cost and intensity, the reference cut-off values were methamphetamine ≥ 0.1 ng/mg; amphetamine ≥ 0.025 ng/mg; 6-monoacetylmorphine ≥ 0.05 ng/mg; morphine ≥ 0.05 ng/mg.The method established in our research can quickly and accurately detect the contents of methamphetamine, amphetamine, 6-monoacetylmorphine, and morphine in hair.This study provides some reference for the public security system to make more rational cut-off values in the norm of drug-related personnel hair samples detection in the future.
