Objective:To observe the clinical effect of warm needling moxibustion at Zhongji (CV 3) and Zusanli (ST 36) in treatment of urinary retention after gynecological surgery. ＜br> Methods: Forty patients with urinary retention after gynecological surgery were randomly divided into two groups by the randomized method, 20 cases in each group. Patients in the treatment group were treated by warm needling moxibustion at Zhongji (CV 3) and Zusanli (ST 36). Patients in the control group were treated by inductive urination. The therapeutic effects of the two groups were observed after one course of treatment. ＜br> Results:The total effective rate was 95.0%in the treatment group and 70.0% in the control group. The difference in the total effective rate between the two groups was statistically significant (P＜0.05). ＜br> Conclusion: Warm needling moxibustion at Zhongji (CV 3) and Zusanli (ST 36) is more effective than inductive urination in treating urinary retention after gynecological surgery.

C-reactive protein (CRP) is an acute phase reaction protein,which is very sensitive to the inflammatory reaction.Many studies have confirmed that CRP is closely correlated with ischemic stroke and atherosclerosis.However,studies on correlation between CRP and intracerebral hemorrhage are less.This article reviews the relationship between CRP and intracerebral hemorrhage.

Objective To detect the asymptomatic cardiovascular changes in children with adenoid hypertrophy.Methods One hundred and twenty children with adenoid hypertrophy underwent both chest X-ray and echocardiography before adenoidectomy,and echocardiography 6 months after operation.Results No child showed an increase in the cardiothoracic ratio on X-ray.But preoperative echocardiography showed an increase in pulmonary artery pressure [(22.6 ±3.6) mm Hg,1 mm Hg =0.133 kPa],a decrease in E/A (1.01 ± 0.17),and an increase in right ventricular end-diastolic diameters [(1.88 ± 0.18) cm].While after operation,pulmonary artery pressure decreased to(17.1 ± 3.2) mm Hg,E/A increased to 1.25 ± 0.12,and right ventricular end-diastolic diameters decreased to (1.67 ± 0.11) cm.Each index change before and after operation was statistically significant(P ＜ 0.05).Conclusion Adenoid hypertrophy can result in clinically asymptomatic cardiopulmonary changes.Early diagnosis and treatment of this disease can prevent serious cardiopulmonary complications.

Objective To investigate whether serum level of low-density lipoprotein cholesterol can predict the expan?sion of hemorrhage growth in elderly male patients with acute hypertensive intracerebral hemorrhage. Methods Patients (n=108) who visited our hospital with from June 2012 until May 2014 spontaneous hypertensive intracerebral hemorrhage with?in 6 hours of onset which is confirmed by initial computed tomography (CT) were sent to repeated CT within 24 hours of on?set. All selected patients were divided into the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. Clinical data of these 2 groups were compared and the relationships of hematoma growth and its risk factors were analyzed. Results Baseline blood pressure, the level of blood glucose, PT, APTT, FIB, PLT and hemorrhage volume did not differ significantly between the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. The ratio of hemorrhage growth in LDL-C<2.49 mmol/L group was significantly higher than that in LDL-C≥2.49 mmol/L group (34.21%vs 11.43%). Multiple logistic regres?sion analysis showed that LDL-C<2.49 mmol/L was the only risk factor contribute to hemorrhage growth. Conclusion Pa?tients with LDL-C<2.49 mmol/L in acute intracerebral hemorrhage are of high risk of hemorrhage growth so early attention and appropriate procedure are needed to prevent or slow its growth.

Objective To investigate the correlation between the red blood cell distribution width (RDW) with risk and and severity of noncardiac ischemic stroke.Methods The patients with acute noncardiac ischemic stroke were enrolled retrospetively and were used as a case group,and the non-stroke patients admitted to the Department of Neurology at the same period were served as a control group.The National Institutes of Health Stroke Scale (NIHSS) was used to assess the baseline neurological deficits.The NIHSS score ＜ 8 was defined as mild stroke and ≥ 8 was defined as moderate to severe stroke.The demographics,clinical data,and RDW were collected and compared.Multivariate logistic regression analysis was used to identify the independent risk factors for the risk of disease and severity of stroke in noncardiac ischemic stroke.Receiver operator characteristic (ROC) curve was used to analyze the predictive value of RDW for acute noncardiac ischemic stroke and its severity.Results A total of 1 173 patients with acute noncardiac ischemic stroke were enrolled.Over the same period,996 non-stroke patients were hospitalized in the Department of Neurology.The RDW in the case group was significantly higher than that in the control group (13.1％ ± 1.0％ vs.12.7％ ±0.7％;t=9.545,t ＜0.001).Multivariatelogistic regression analysis showed that RDW (odds ratio [OR] 9.920,95％ confidence interval [CI] 6.286-15.655,P＜ 0.001) was an independent risk factor for acute noncardiac ischemic stroke.ROC curve analysis showed that the RDW cutoff value for predicting acute noncardiac ischemic stroke was 12.55％,the area under the ROC curve was 0.611 (95％ CI 0.588-0.635),the sensitivity was 73.3％,the specificity was 43.7％,the positive predictive value was 60.5％,the negative predictive value was 58.2％,and the accuracy was 59.7％.RDW in the moderate to severe stroke subgroup was significantly higher than that in the mild stroke subgroup (13.7％ ± 1.6％ vs.12.9％ ± 0.6％,t =-13.794,P＜ 0.001).Multivariate logistic regression analysis showed that RDW (OR 3.835,95％ CI 3.002-4.899,P ＜ 0.001) was an independent risk factor for the severity of acute non-cardiac ischemic stroke.ROC curve analysis showed that the RDW cutoff value for predicting moderate to severe non-cardiac ischemic stroke was 13.45％,the area under the ROC curve was 0.713 (95％ CI 0.674-0.752),the sensitivity was 47.7％,the specificity was 86.1％,the positive predictive value was 49.8％,the negative predictive value was 85.1％,and the accuracy was 77.6％.Conclusions RDW is an independent risk factor for acute non-cardiac ischemic stroke.Increased RDW is associated with the severity of acute non-cardiac ischemic stroke.

Objective To explore the effect of repetitive transcranial magnetic stimulation(rTMS)on spinal cord injured rats.Methods Weight-drop spinal cord injury model was made at thoracic 10 segments with NYU impactor device.Stimulated group received daily superthreshold rTMS continued for 4 weeks.BBB locomotor scores were recorded weekly.Growth associated protein 43(GAP43)and 5-hydroxytryptamine(5-HT)were detected with immunofluorescence staining in the area of rostral and caudal to the lesion.Results The BBB scores in stimulation group improved compared with that in the control(P<0.01).GAP43 and 5-HT markers increased in the stimulation group(P<0.01),and they increased in the rostral than in the caudal areas(P<0.01).Conclusion rTMS can improve the locomotor function of incomplete spinal cord injury rats,which may result from the increase of expression of GAP43 and 5-HT.

Objective To investigate the effect of repetitive transcranial magnetic stimulation(rTMS)on the spinal segmental excitability after spinal cord injury in adult rats.MethodsT 10 spinal cord injury models were made with weight-drop method.8 weeks later,rTMS were applied to the experimental group at 0.5 Hz suprathreshold stimulation,500 pulses daily for 4 weeks.Spinal cord injury rats without stimulation and normal rats were used as controls.At different time points,electronic evoked F-wave were measured.The ratio of F-wave amplitude to M-wave amplitude(F/M)were compared among these groups.Immunohistochemistry was used to detect the expression of 5-hydroxytryptamine(5-HT)in the rostral and caudal lesion segments.ResultsThe ratio of F/M increased significantly(P<0.01)8 weeks after spinal cord injury compared with baseline ratio and regressed significantly(P<0.01)after 4 weeks of rTMS.Expression of 5-HT in grey matter around lesion was decreased after spinal cord injury and increased significantly(P<0.01)both in the rostral and caudal lesion segments in rTMS treatment group.ConclusionThe increased spinal segmental excitability after spinal cord injury can be regressed by rTMS,which may be resulted in increased expression of 5-HT.

Objective To explore the conditions and methods for cryopreservation and proliferation of mouse spermatogonial stem cells (SSCs). Methods SSCs were isolated from six-day-old Kunming mouse using two-step enzymatic digestion and Percoll discontinuous density gradient centrifugation. Cells were frozen with different freezing medium and cooling rate. After thaw, they were cultured in mimimum essential medium alpha (MEMα) supplemented with 10% fetal calf serum (FCS) and 100μg/L glial cell line-derived neurotrophic factor (GDNF). The survived and proliferating SSCs were examined by WST-8 colorimetric assay. Alkaline phosphatase andreverse transcription-polymerase chain reaction (RT-PCR) were performed to confirm if the cultured 96 hours germ cells were still stem cells. Results The best method to cryopreserve SSCs is using cryoprotector containing 10% dimethyl sulfoxide(DMSO), 10% FCS, 0.07mol/L sucrose and 1℃/min cooling rate, and the viability of cells in this method is more than 84%;Although the cell viability in non-programmed freezing method is less than that in the programmed freezing method, it is a simple and effective cropreservation method for mouse SSCs. What is more, the anchoring time of SSCs in this method is 8-12 hours after thaw, SSCs begin to proliferate 24 hours later, and rapid proliferation appears on the 48 hours, colonies are composed by 20-25 cells in 96 hours, when SSCs proliferated nearly 5 times.Conclusion The culture condition we used is suitable for proliferation of frozen-thawed SSCs.

Objective To explore the influence of seasonal variations on acute cerebral infarction outcome. Meth-ods We collected data from acute cerebral infarction patients in the Second Hospital of Tianjin Medical University from January 2009 to February 2012. All cases were classified by months and seasons into different groups to analyze the season-al variations retrospectively.
