In this study, sonography video urodynamic studies (SVUDS), which combined synchronically urodynamic studies with trans-perineal and trans-abdominal sonography, were used to detect female bladder outlet obstruction (FBOO). The dynamic changes of urethra and surrounding pelvic floor structure during storage and voiding phase were observed by SVUDS and the causes of FBOO were analyzed. And the findings were as follows: 13 patients showed organ prolapse, there was an urethral angulation deformity during urination; 5 cases had abnormal urination as the urethral opening was not good in the middle of urination period; 4 cases had urethral stricture, as the proximal end of the obstruction dilated during urination, and the obstruction site showed no relaxation; 1 case had primary bladder neck obstruction with an incomplete opening of the bladder neck during urination; 3 cases had idiopathic bladder outlet obstruction and the sphincter of bladder neck and urethra opened well during urination.

Objective To study the relation of esophageal motility and acid reflux between gastroesophageal reflux disease (GERD) patients with and without esophageal injury.Methods A total of 25 patients who met the GERD diagnosis criteria were conducted esophageal-gastric-duodenal endoscopy examination and followed with high-resolution esophageal manometry.The changes of esophageal pH postprandial were also detected.The differences of esophageal motility and acid reflux time between GERD patients with and without esophageal injury were compared.Patients were divided into non-acid reflux group and acid reflux group according to DeMeester score.The changes of esophageal motility indexes of these two groups were compared.Wilcoxon test and t test were used for statistical analysis.Results There was no significant difference in baseline value of lower esophageal sphincter (LES) pressure,remained LES pressure,speed of the esophageal peristalsis,the time of esophageal pH＜4 and DeMeester score between groups with and without esophageal injury (all P＞0.05).But esophageal contraction amplitude of group with esophageal injury was lower than that of group without esophageal injury (31.9 mm Hg vs 64.2 mm Hg,1 mm Hg=0.133 kPa,Z=-2.37,P=0.02).There was no significant difference in baseline value of LES pressure,remained LES pressure,speed of the esophageal peristalsis between acid reflux group and non acid reflux group (all P＞0.05).But the esophageal contraction amplitude of acid reflux group was lower than that of non acid reflux group (36.4 mm Hg vs 71.8 mm Hg,Z=-2.25,P=0.02).Conclusions There was no significant correlation between the LES pressure and esophageal acid reflux with esophageal injury in GERD patients.Esophageal peristalic contraction may be associated with esophageal injury and acid reflux.

Objective To observe the clinical efficacy of acupuncture-moxibustion plus moving cupping on the back in treating sub-health in the undergraduates. Method According to the theory of preventive treatment in the Chinese medicine, 30 undergraduates with sub-health were treated by acupuncture at Baihui (GV20), Guanyuan (CV4), and bilateral Zusanli (ST36), plus moving cupping to the Governor Vessel, totally for 20 d. The Self-rating Sub-health Scale (SRSHS) was adopted for evaluation before and after intervention, for observing the clinical efficacy. Result Of the 30 subjects, 14 were recovered, 14 showed effective, 2 failed, and the total effective rate was 93.3%. The SRSHS score dropped significantly after intervention (P＜0.001). The psychological factor responded most significantly to the intervention, followed by the physical factor, while the social function factor didn’t show a significant change. Conclusion Acupuncture-moxibustion plus moving cupping is significantly effective in improving and treating the sub-health state in the undergraduates.

Aim To investigate the mechanism of the combination of guggulsterone and temozolomide in inhibiting human glioblastoma cells.Methods Glioblastoma U251 cells were treated with guggulsterone and temozolomide alone or in combination.Cell proliferation was determined by CCK-8.The level of apoptosis was evaluated by Hoechst 33342 staining and flow cytometry.PI3K/Akt pathway activity and the level of apoptosis-associated proteins Bcl-2 and Bax expression were analysed by Western blot.Results Guggulsterone(30 μmol·L-1)significantly enhanced the inhibitory effect of temozolomide(1~400 μmol·L-1)on U251 cells, as compared with temozolomide treatment alone.Guggulsterone(30 μmol·L-1)significantly enhanced the effect of temozolomide(400 μmol·L-1)-induced apoptosis on U251 cells, as compared with temozolomide treatment alone(P<0.01).Furthermore, guggulsterone(30 μmol·L-1)significantly down-regulated the expression of PI3K, p-PI3K p110, p-Akt(Ser473)and Bcl-2, as compared with temozolomide treatment alone.Conclusion Guggulsterone enhances the inhibitory effect of temozolomide on human glioblastoma U251 cells through PI3K/Akt pathway.

Objective To investigate the role of clinical pharmacist in anti-infection therapy for patients with augmented renal clearance (ARC).Methods A case with multi-site severe infection after traffic accident was treated with anti-infection therapy.According to the characteristics of infection and pharmacokinetics,clinical pharmacist discussed the intervention by clinical pharmacist in terms of formulating anti-infection program and adjustment of individual dose.Results After consultation and evaluation by clinical pharmacist,the patient was diagnosed as ARC.According to pharmacokinetics characteristics reported by literature,vancomycin was adjusted to 1 g (once per 8 h).Based on detection result of pathogenic bacteria,meropenem was replaced by cefoperazone/sulbactam,and the dose was increased to 3 g (once per 6 h).And then,vancomycin concentration was detected again,and it reached ＞ 10 μg· mL-1;pathogenic bacteria culture result was negative.This patient obtained good therapeutic effect.Conclusion Clinical pharmacist could assist physician on anti-infection treatment and dose adjustment of ARC patient,and improve ARC patient's therapeutic effect.

Objective To evaluate the surgical modalities and prognosis in elderly patients with gastric cancer.Methods Sixty three gastric cancer patients aged ≥≥ 75 years underwent radical surgery,with D0 + D1 resection in 32 cases and D2 resection in 31 cases,in Beijing Hospital from January 2005 to December 2009.Results More lymph nodes were dissected in D2 group than those in D0 + D1 group (27.42 ± 12.75 vs.14.59 ± 12.11,t =-4.095,P ＜ 0.05).There was no significant difference in postoperative complication rate [25.81％ (8/31) vs.31.25％ (10/32),x2 =0.095,P ＞ 0.05] and perioperative death rate [3.23％ (1/31) vs.6.25％ (2/32),x2 =0.324,P ＞ 0.05] between two groups.The 5-year survival rate was higher in D2 group than that in D0 ± D1 group (47.3％ vs.21.4％,x2 =6.346,P ＜ 0.05).The 5-year survival rate was higher in POSSUM score (PS) ＜ 20 group than that in PS≥20 group (46.3％ vs.11.1％,x2 =5.492,P ＜0.05).In PS≥20 group,postoperative complication rate did not increase after D2 radical resection(1/8 vs.3/10,x2 =0.824,P ＞ 0.05).Univariate analysis showed that PS ＜ 20 was associated with the prognosis of patients (x2 =5.492,P ＜ 0.05).Cox proportional hazards model showed that lymph node metastasis (OR=4.103,95％ CI:1.790-9.405,P ＜ 0.05) and D2 radical gastrectomy(OR =0.313,95％ CI:0.158-0.620,P ＜ 0.05) were the independent factors associated with the prognosis of patients aged ≥ 75 years with gastric cancer (all P ＜ 0.05).Conclusion Standardized D2 lymph node dissection is beneficial for gastric cancer patients aged ≥75 years.PS ＜ 20,lymph node metastasis and D2 radical gastrectomy are associated with the prognosis of patients.

Objective To establish the animal model of chronic thromboembolic pulmonary hypertension(CTEPH) and to compare the accuracy of dual-energy CT (DECT) pulmonary angiography and histopathology for detecting CTEPH. Methods Eighteen canines were included in the study. All canines underwent paracentesis, embolization, CT scanning, pressure measurement and tranexamic acid feeding. The procedures were repeated every two weeks, until systolic/diastolic pressure in canines was≥30/15 mmHg or mean pulmonary artery pressure ≥ 20 mmHg.And then canines were sacrificed for histopathology examination. For CT pulmonary angiography (CTPA)in DE mode and DECT lung perfused blood volume (Lung PBV) images, the presence or absence of PE or perfusion defects were recorded on a per-canineand aper-lobe basis. With histopathological results as reference standard, the sensitivity, specificity of CTPA and lung PBV to detect PE were computed for two readers. The pairedχ2 test (McNemar test) was used to analyze the difference in diagnostic accuracy between CTPA and Lung PBV. Inter-reader agreement was also calculated with kappa test. Results CTEPH was demonstrated in 13 canines. On a per-canine basis, both readers found uneven and peripheral perfusion defects with DECT in 11 canines (84.6%, 11/13); while 5 canines (38.5%, 5/13) had cutoff or sudden stenosis of pulmonary arteries with CTPA;on a per-lobe basis,
both readers had sensitivities of 14.3%(5/35), 83.3%(30/36), specificities of 100.0%(30/30), 100.0%(29/29), accuracies of 53.8%(35/65), 90.8%(59/65)for CTPA and DECT, respectively. DECT had a higher sensitivity(χ2=-4.690,P<0.01)and accuracy(χ2=8.284,P<0.01) in detecting CTEPH. Excellent and moderate inter-reader agreements were observed with CTPA and DECT (Kappa=0.938, 0.572, both P<0.001). Conclusions It is feasible to make a CTEPH animal model with autologous thrombus. DECT shows a higher accuracy than CTPA to detect CTEPH in this canine model study.
