Objective To evaluate the clinical value of interventional chemotherapy and intravesical instillation for preventing postoperative recurrence and metastasis of cancer in urinary bladder.Methods One hundred and eight patients with urinary bladder cancer were divided into group A and group B.Intravesical instillations after surgical operation were performed in group A (n=52) and combined interventional chemotherapy and intravesical instillations after operation were performed in group B (n=56).The patients were followed up for 1 - 3 years.Results In group A,recurrence occurred in 5 cases (9.62%) within one year,and in 23 cases (44.23%) within 3 years after the operations metastasis developed in 21 cases (40.38%),and 18 cases (34.62%) died.In group B,recurrence occurred in 2 cases (3.57%) within one year,and in 11 cases (19.64%) within 3 years after the operation;metastasis developed in 7 cases (12.50%), and 5 cases (8.93%) died.There were statistical significant differences in recurrence,metastasis and mortality between these two groups (P

This study was aimed to compare the mechanical characteristics under different physiological load conditions with three-dimensional finite element model of rigid fixation and elastic fixation in the lumbar. We observed the stress distribution characteristics of a sample of healthy male volunteer modeling under vertical, flexion and extension torque situation. The outcomes showed that there existed 4-6 times pressure on the connecting rod of rigid fixation compared with the elastic fixations under different loads, and the stress peak and area of force on elastic fixation were much higher than that of the rigid fixations. The elastic fixation has more biomechanical advantages than rigid fixation in promoting interbody lumbar fusion after surgery.

Objective To investigate the ability of social cognition in patients with right temporal lobe infarction.Methods Fifteen patients with temporal lobe infarction (TLI) and 20 healthy controls (HC) were examined with the recognition of faux pas and reading the mind in the eyes tasks for assessing the ability of social cognition.Results The TLI group performed significantly worse when compared with the HC group (28.6 ± 6.1,36.4 ± 4.3 respectively) as revealed in the total faux pas-related scores (U =41.00,P <0.01).For the control question,there was no significant difference between the TLI group and the HC group (9.86 ±0.35,10.00 ± 0.00 ; U =130.00,P =0.097).In the reading the mind in the eyes task,patients with TLI performed worse than the HC group(17.13 ±6.41,29.75 ±2.07 respectively),and the difference had statistical significance (U =0.00,P < 0.01).But there was no significant difference in gender recognition judgment (30.37 ± 1.16,31.35 ± 1.08 respectively; U =106.00,P =0.129).Conclusions The right temporal lobe involves in social cognition.Moreover,the right temporal lobe not only involves in the verbal related social cognitive processing,but also involves in the no-verbal related social cognitive processing.

Lesion was made individually to the various cortical areas in 14 rats.The cortico- fugal fibers terminating into cochlear nuclei were traced in sections by means of the modified Nauta and Fink-Heimer silver staining method.The results were as follows: 1.After damaging the auditory area or somato-sensory area 1(SI)of the cerebral cortex unilaterally,degenerating fibers were found bilaterally in the ventral and dorsal cochlear nuclei.This result showed that the above cortical areas have direct descending connection with the cochlear nuclei. 2.No degenerating fibers were found in the cochlear nuclei after the ablation of the motor or visual area of the cerebral cortex,which demonstrated that the cochlear nuclei do not receive descending fibers from the above cortical areas. 3.The pathway from the cerebral cortex to the cochlear nuclei was:The descending fibers which originated from the auditory area or SI area ipsilaterally passed through the capsula interna and basis pedunculi,and part of these fibers passed dorsally and downward to the lateral portion of the reticular formation of the midbrain;and from there the fibers passed through the lemniscus lateralis and dorsal acustic stria to the cochlear nuclei of the ipsilateral side.The cochlear nuclei in contralateral side also received the corticofugal fibers by way of the dorsal acustic stria.These fibers might cross to the contralateral side at the region in the posterior commissure,superior colliculus commissure and inferior colliculus commissure.

B-ultrasonography and/or CT scannings of 84 cases of enlarged superior ophthalmic vein (SOV) were analysed morphologically and etiologically. Carotid-cavernous fistula, ophthalmic Graves disease, Tolosa-Hunt syndrome, orbital vascular deformity, inflammation at the apex of the orbit, orbital pseudo tumor, intraorbital hematoma and thrombosis of the SOV might induce enlargement of SOV. Associated with other Findings of intraorbital tissues revealed by CT and B-ultrasonography, the etiological diagnosis of the enlarged SOV could be made. The dynamic findings of the SOV rendered by B-ultrasonography and Doppler ultrasonic play an important role in the diagnosis of carotid-cavernous fistula.

In this study, the psbA-trnH sequence as DNA barcode was used to evaluate the accuracy and stability for identification pteridophyte medicinal material Pyrrosiae Foliumas from adulterants. Genomic DNA from 106 samples were extracted successfully. The Kimura 2-Parameter (K2P) distances and ML tree were calculated using software MEGA 6.0. The intra-specific genetic distances of 3 original plants were lower than inter-specific genetic distances of adulterants. The ML tree indicated that Pyrrosiae Folium can be distinguished from its adulterants obviously. Therefore, the psbA-trnH sequence as a barcode of the pteridophyte, can accurately and stably distinguish Pyrrosiae Folium from its adulterants.

Objective To evaluate the clinical efficacy and safety of domestic Sirolimus-eluting stents (Firebird) and imported Zotalimus-eluting stents ( Resolute) in the treatment of patients with unprotected left main coronary artery disease ( ULMCA) . Methods We retrospectively enrolled 76 patients with ULMCA treated by percutaneous coronary intervention (PCI) under the guidance of IVUS in our hospital. According to the different stents used in the procedure, the patients were divided into two groups: Domestic Sirolimus-Eluting Stents group (Firebird group, n = 42) and Imported Zotarolimus-Eluting Stents group (Resolute group, n = 34) . We analyzed the baseline characteristics, coronary artery lesion characteristics, stenting strategies and any changes in left ventricular ejection fraction ( LVEF) in both groups and investigated the long-term clinical outcomes. Results There were no significant differences in the baseline characteristics, the SYNTAX scores of the coronary artery lesion and the rate of complete revascularization between the two groups. Compared with that in Firebird group, there were more cases involving the distal left main (79. 4% vs. 45. 2% , P ﹤ 0. 05) and more patients using two stents strategies (29. 4% vs. 7. 1% , P ﹤ 0. 05) in the Resolute group. The change in LVEF post-PCI had no difference between the two groups. The patients were followed up for a mean of (23. 3 ± 10. 7) months. During the follow-up period, the occurrence of MACCE had no significant difference between the two groups. In the Firebird group, there were one sudden cardiac death, one nonfatal myocardial infarction, one stroke and five patients with recurrence of angina pectoris. In the Resolute group there were one sudden cardiac death, one target lesion revascularization and four patients with recurrence of angina pectoris. Conclusions Compared with the imported Zotalimus-Eluting Stents, the domestic Sirolimus-Eluting Stents are safe and effective in the treatment of patients with unprotected left main lesions under the guidance of IVUS. The two kinds of stent showed similar long-term clinical outcomes.

The changes of interstitial cells of Cajal(ICC)distribution and connexin 43(Cx43)expression in gastric muscle layers were assayed in gastroparesis models of streptozotocin-induced diabetic rats.The results showed that gastric emptying was significantly delayed,the contraction frequency and amplitude of gastric muscle segments were greatly decreased,Cx43 gray values were significantly increased and Cx43 distributed homogeneously with ICC immunopositivity in the model rats.These changes appear to be related to the pathogenesis of diabetic gastroparesis.
