Objective:To compare the oncology effect and risk between hepatopplenectomy and conventional hepatectomy for hepatocellular carcinoma patients with hypersplenism, so as to provide guidance for clinical application.Methods:One hundred and eighteen patients with hepatic carcinoma with hypersplenism in the Private hospitals of Zhejiang Province Yiwu were studied retrospectively. Patients were divided into 2 groups according to different operation methods: combined hepatosplenectomy group and conventional hepatectomy group with 59 cases in each group. Blood routine, liver function, complication and tumor effect (local recurrence, distant metastasis and 1, 3, 5 years survival rate) was compared between two group.Results:There was no significant difference in operation time, intraoperative blood loss and hospitalization time between the two groups ( P>0.05). Compared with that of the control group, the clinical total effective rate of the combined group was significantly increased: 94.92% (56/59) vs. 79.66% (47/59), P<0.05; there was no significant difference in the incidence of complications between the two groups ( P>0.05); the two groups were followed up to August 1, 2019. The median survival time of the two groups was significantly higher than that of the open group (29 months vs 22 months) ( P<0.05); the local recurrence rate, distant metastasis rate, 1, 3 and 5-year survival rate between the two groups were statistically significant ( P<0.05). The platelet and white blood cells in the combined group were significantly higher than those in the control group after 7 days′ treatment: (264.48 ± 75.37) × 10 9/L vs. (153.53 ± 42.11) × 10 9/L, (7.86 ± 1.43) × 10 9/L vs. (3.48 ± 1.32) × 10 9/L, P<0.05. Compared with that of the control group, alanine aminotransferase and aspartate aminotransferase were significantly decreased: (49.42 ± 31.88) U/L vs. (84.22 ± 43.95) U/L, (36.50 ± 21.50) U/L vs. (49.98 ± 35.63) U/L, P<0.05. Conclusions:Compared with conventional hepatectomy for hepatocellular carcinoma patients with hypersplenism, combined hepatosplenectomy can effectively promote the increase of peripheral blood PLT and WBC and the recovery of liver function without increasing the risk of surgery, and the long-term follow-up results are more satisfactory, which has high clinical application value.

ObjectiveTo explore the effect of earlier rehabilitation on activities of daily living(ADL) of patients with spinal cord injury(SCI).Methods50 SCI patients received earlier rehabilitation and improvement of ADL of patients was evaluated.ResultsAfter two months treatment,the scores of Barthel index,functional independence measure(FIM) grade of patients increased significantly compared with that of before treatment(P<0.05) and ADL improved.ConclusionEarlier rehabilitation can improve ADL of SCI patients.

Objective To evaluate the value of cough test in the tension-free vaginal tape (TVT)procedure.Methods A cohort of 85 women with stress urinary incontinence underwent the TVT procedure with cough test (n =41) or without cough test (n =44).Patients in cough test group were performed according to the Ulmsten’s method strictly,with the stress of tape adjusted in light of cough test; whereas in other 44 operations,the tape was placed on the urethral tract without stress,and no cough test was performed.The urine catheter was removed after 48 hours postoperatively and follow-up evaluation was carried out at 12 month postoperatively.Results TVT procedure was carried out successfully in all patients by a single experienced surgeon.Four cases of urinary retention and 5 cases of voiding difficulty were observed in the cough test group.However,urinary retention or voiding difficulty was not detected in the nun-cough test group.Based on the twelve-month follow-up results,the cure rate was 92.6％ (38/41) in the cough test group and 93.1％ (41/44) in the non-cough test group.Flow-pressure study indicated that 11 cases in cough test group were in the obstruction zone,while only 3 cases in the obstruction zone were detected in the non-cough test group.Conclusions TVT is a safe as well as effective minimally invasive surgical procedure to treat female stress urinary incontinence.However,Adjusting stress of tape in accordance with cough test during the TVT may potentially increase the incidence of urinary dysfunction postoperatively.Therefore,no convincing evidence was gained to support the efficacy of cough test during TVT in terms of preventing postoperative voiding dysfunction.

Objective To screen for the potential protein biomarkers in serum for the diagnosis of idiopathic Parkinson's disease (PD) using proteomic fingerprint technology. Methods Proteomic fingerprint technology combining weak cation exchange (WCX) magnetic beads with MALDI-TOF-MS was used to identify and compare the serum proteins from 61 patients with idiopathic PD, 29 patients with other neurodegenerative diseases (OND) and 30 healthy blood donors. Model of biomarkers and proteomics patterns associated with PD was analyzed by Biomarker Patterns Software. The model also was validated by 40 newly recruited PD cases. Results A total of 17 discriminating M/Z peaks which were related to PD were identified ( nonparametric test, Z:-4.039--2.633, P<0.01 ). Five biomarkers with M/Z of 6121, 5234, 2961,4309 and 8170 respectively generated an excellent model of distinguishing between PD and healthy groups. The sensitivity was 98.4% and the specificity was 83.1%. Blind testing in 40 newly recruited cases demonstrated a sensitivity of 85.0% (17 of 20 PD) and a specificity of 70. 0% (14 of 20 controls). Conclusions Combination of WCX magnetic beads with MALDI-TOF-MS is a useful method in establishing proteomic patterns associated with PD. It also may be used to construct a diagnostic model with PD Biomarkers. Although this model of biomarkers fails to distinguish between PD and OND controls, it is able to differentiate PD from healthy controls.

Objective To investigate the feasibility of setting mAs in liver enhanced CT scan according to plain scan noise with fixed mA CT scanner,in order to reduce the radiation dose.Methods One hundred continuous patients underwent liver enhanced CT scan (group A) prospectively.Two hundred and fifty mAs was used in plain and enhanced CT scans.Noises of plain and venous phase CT images were measured,and the image quality was evaluated.The equation between mAs of enhanced scan and noise of plain scan image was derived.Another 100 continuous patients underwent liver enhanced CT scan (group B).Enhanced scan mAs was calculated from noise on plain scan by using the equation above.Noises on venous phase images were measured and the image quality was measured.Based on body mass index (BMI),patients in groups A and B were divided into three subgroups respectively:BMI ＜ 18.5 kg/m2,18.5 kg/m2 ≤ BMI ＜ 25.0 kg/m2 and BMI ≥ 25.0 kg/m2.Image quality score was compared with nonparametric rank sum test,CT dose index (CTDI) and effective dose (ED) were measured and compared between each subgroup with 2 independent samples t or t' test.Results The equation between enhanced scan mAs (mAsX) and plain scan noise (SDp) was as follows:mAsX =mAs1 × [(0.989 × SDp + 1.06) /SDx]2,mAs1 =250 mAs,SDx =13.In patients with BMI ＜ 18.5 kg/m2,ED of group A [(6.86 ±0.38) mSv,n =12] was significantly higher than group B [(2.66 ±0.46) mSv,n =10)] (t =18.52,P ＜0.01).In patients with 18.5 kg/m2 ≤ BMI ＜ 25.0 kg/m2,ED of group A [(7.08 ± 0.91) mSy,n =66] was significantly higher than group B [(4.50 ± 1.41) mSv,n =73] (t' =10.57,P ＜ 0.01).In patients with BMI ≥25.0 kg/m2,there was no significant difference between EDs of group A (7.54 ± 0.62 mSv,n =22) and group B [(8.19 ±3.16) mSv,n =17] (t' =0.89,P =0.39).Image quality of 5 patients in group A and none in group B did not meet the diagnostic requirement.Conclusion Setting mAs of enhanced scan according to plain scan noise could reduce the radiation dose with maintainence of image quality.

[ ABSTRACT] AIM:To investigate the biological characteristics of newborn rabbit tracheal chondrocytes in vitro. METHODS:Newborn rabbit tracheal chondrocytes were obtained by the method of enzyme digestion, and then cultured in monolayer in vitro.Morphological and growth observations were performed under inverted phase contrast microscope.The ultrastructures of the cells were observed under scanning electron microscope and transmission electron microscope.The bi-ological characteristics of secreted extracellular matrix components were detected by real-time PCR, immunocytochemistry staining and toluidine blue staining.RESULTS: Newborn rabbit tracheal chondrocytes isolated and cultured in vitro showed short triangular or irregular shapes, and adherent growth very well.The ultrastructures of the cells showed pore and abundant cytoplasm and organelles, with a lot of protein secretions in the cells.The chondrocytes expressed the mRNA of collagen I, collagen II and proteoglycans, mainly collagen II and proteoglycans.Immunocytochemistry staining showed col-lagen II and SOX9 positive, and collagen I weakly positive.Toluidine blue staining was also positive.CONCLUSION:Enzyme digestion and monolayer culture are suitable method to obtain newborn rabbit tracheal chondrocytes.These cells, secreting extracellular matrix components, are able to be selected as seed cells for tissue engineering of trachea in vitro, and used to study the therapeutic method for neonatal rabbit tracheal stenosis.

Objective To compare 99Tcm-MIBI MPI with delayed enhancement MRI (DE-MRI) in patients with idiopathic dilated cardiomyopathy (IDCM). Methods Forty patients with IDCM were included. They underwent both rest 99Tcm-MIBI myocardial perfusion imaging and DE-MRI within 7 days. 99Tcm-MIBI MPI was performed to identify diffuse or segmental abnormal perfusion patterns including reduced or defect perfusion segments. DE-MRI images were divided into 4 categories: no delayed enhancement, septal, subendocardial and transmural delayed enhancement, x2 test was used for data analysis. Results Diffuse and segmental perfusion abnormality on 99Tcm-MIBI MPI were found in 19 (47.5%) and 21 (52.5%)patients respectively, while DE-MRI enhancement was simultaneously found in 5 patients of the former (5/19, 26.3%) and 18 (18/21, 85.7%) of the latter (x2 =14.401, P＜0. 001). For those (n=18) with both segmental perfusion abnormality and DE-MRI enhancement, the number of segments of the 4 DE-MRI respectively. A significant difference was found in the DE-MRI enhancement categories between normal and defect perfusion segments (x2 = 29. 183, P ＜0.001 ) and between reduced and defect perfusion segments as well (x2 =25. 110, P＜0. 001). Conclusions Both diffuse and segmental perfusion abnormalities on 99Tcm-MIBI MPI can be found in patients with IDCM. DE-MRI enhancement is more frequently found in patients with segmental perfusion abnormality.

Objective To investigate the expressions of protein gene product 9.5 (PGP 9.5),cathepsin D(CAD) and S-100 protein(S100) and their significance in the colon of the patients with hirschsprung′s disease(HD).Methods Thirty stenotic segments from children with HD and 35 controls were stained for PGP 9.5 and CAD and S100 by immunohistochemistry.The expressions were observed by imaging analysis system.Results 1.In the controls,CAD was only positive to ganglionic cells,which could be observed in myenteric and submucosal plexuses.Schwann cells and perineural satellite cells and nerve fibers were positive to PGP 9.5 and S100,ganglionic cells were positive to PGP 9.5,and were stained negative to S100,which left "cells-like blank area" in the plexuses.2.In the stenotic segments of HD,neither CAD-positive and PGP 9.5-positive neurons nor "cell-like blank area" in S100 staining were found in the plexus.The PGP 9.5 and S100 positive fibers were proliferated obviously in number.There were obvious differences in the density of the S100 stained nerve fibers and the fiber sizes between the controls[169.25?9.53;(23.15?5.56) ?m ] and the stenotic segments of HD[146.70?10.87;(57.81?14.99) ?m](all P
