Objective:To provide better clinical treatment plan by grading and classifying four-dimensional ultrasound pelvic floor dynamic imaging primiparas pelvic floor dysfunction.Methods: 270 cases with pelvic floor functional disorders (bladder prolapse) of high-risk mothers were selected, from the beginning of the median sagittal plane and three-dimensional reconstruction of the surface at rest, to observe the bladder and urethra and pelvic diaphragm hiatus and anal status under Valaslva changes in the measurement parameters (bladder neck mobility, posterior horn of bladder and urethra, rotation angle of the urethra) and its Green typing.Results: There was no statistical difference between the mode of delivery cystocele resting corresponding BSD and posterior horn of bladder and urethra (t=1.133,t=1.165;P>0.05). Under Valsalva state, there were significant differences the two groups corresponding to BSD, the bladder neck mobility, posterior horn of bladder and urethra and rotation angle of the urethra (t=2.147,t=5.628,t=3.502,t=4.396;P<0.05). The incidence rate of type II and type III in vaginal delivery group is higher than that in cesarean section group. The incidence rate of type I in vaginal delivery group is less than that in cesarean section group. The differences were statistically significant (x2=6.080,P<0.05). Conclusion: The pelvic floor dynamic four-dimensional ultrasound imaging can clearly show the situation of pelvic floor before primiparas to understand the situation of maternal mode of delivery cystocele production. It can provide a more reliable basis for early clinical diagnosis of maternal pelvic floor dysfunction.

Objective:To use the perineum four-dimensional pelvic ultrasound stereo imaging for detecting injury situation of pelvic diaphragm hiatus and anal levator ani muscle. Understand abnormal classification of pelvic floor muscle. investigate the application of four-dimensional pelvic ultrasound stereo imaging in pelvic floor dysfunction (PFD) for primipara in order to provide more accurate data for clinical practice.Methods: 270 primiparas with pelvic floor dysfunction were divided into the vaginal delivery group (135 cases) and selective cesarean group (135 cases) as random number table; pelvic floor muscle strength, longitudinal diameter, transverse diameter, area of pelvic diaphragm hiatus and thickness of the anus levator were detected by the perineum four-dimensional pelvic ultrasound stereo imaging, respectively, and then to compare differences between the two groups. Results: In 270 cases, 162 cases (60%) were abnormalities in pelvic floor muscle strength, and 189 cases (70%) were abnormalities in vaginal pressure; the results of pelvic floor muscles fatigue grade situation revealed: 127 cases were abnormal muscle fiber strength ofⅠtype (47%), 30 patients were abnormal muscle fiber strength ofⅡ type (11%). There were no significant differences between the two groups in the abnormal rate of pelvic floor muscle strength, vaginal pressure and muscle fiber strength. Longitudinal diameter, transverse diameter and area of pelvic diaphragm hiatus in the vaginal delivery group were higher than that in the selective cesarean group, while thickness of anal levator were thinner than that in the selective cesarean group with significant differences (t=3.730,t=3.467, t=3.826,t=1.809;P<0.05).Conclusions: The perineum four-dimensional ultrasound diagnosis can intuitively and clearly show morphological characteristics of female pelvic diaphragm hiatus, therefore, it can quickly finish diagnosis, and provide the basis for clinical diagnosis and treatment evaluation of postpartum PFD.

AIM: Currently available anti-scarring regimens for glaucoma filtration surgery have potentially blinding complications and safer alternatives would be beneficial. This experiment is to investigate the effect of TGF-β2 antisense oligodeoxynucleotide on differentiation, proliferation of subconjunctival fibroblast following glaucoma filtration surgery.METHODS: Glaucoma filtration surgery were performed on both eyes of 28 rabbits. TGF-β2 antisense oligodeoxynudeotide was subconjunctivally injected in the right eyes (A group), and TGF-β2 missense oligodeoxynucleotide (B group)or PBS(C group) was used at the same method in the left eyes as controls. Rabbits were killed at 4,7,14 and 28 days after surgery. Intraocular pressure (IOP), bleb characteristics were recorded at different time point. Subconjunctival fibroblasts were examined by immunohistochemistry and electron microscopy.RESULTS: The IOP of rabbits in group A was significantly lower at 14 days (6.74± 1.18 mmHg) and 21 days (8.15± 1.97mmHg) after operation than the IOP in group B (8.53± 1.04,9.72± 1.09 mmHg)(P ＜0.01) and group C(8.79± 1.21, 9.43±1.27 mmHg) (P ＜0.05). The mean bleb survival time was longer (17.2 days) in group A than that of group B (14.5 days) and group C (13.5 days)(P＜0.05). The population of the cells expressing α -smooth muscle actin(α -SMA) and proliferating cell nuclear antigen (PCNA) was significantly reduced in group A compared with the group B and C. The ultrastructure of fibroblast was not altered by TGF-β2 anti-sense oligodeoxynucleotide.CONCLUSION:TGF-β2 antisense oligodeoxynucleotide can prevent the scar formation after glaucoma surgery by inhibit the differentiation and proliferation of subconjunctival fibroblast. It could be a potentially useful anti-scarring alternative for the prevention of late surgical failure.

BACKGROUND:Obsolete lateral ankle ligament injury is frequently treated by Chrisman-Snook operation.However,this operation destructs some peroneus brevis tendon,and affects the function of peroneus brevis tendon for foot valgus.OBJECTIVE:Based on previous research,to investigate the effect of allogeneic tendon for reconstruction of ankle lateral ligaments.METHODS:A total of 17 cases of ankle lateral ligament injured were selected,with a course of disease from 3 to 6 months.All lateral ligaments were reconstructed by allogeneic tendon & anchors.During the operation,a drill,4.5 rnm diameter,was used to drill a hole on the lateral ankle;one anchor was drilled into the talus at the end of anterior talofibular ligament,another one was threaded on the calcaneus;the allogeneic tendon was permeated through the hole on the lateral ankle,maintaining ankle neutral and moderate valgus position.The allogeneic tendon was sutured with the thread of the anchors.Following operation,the ankle was fixed in neutral position and slightly valgus position;wound healing,AOFAS score and stress radiograph were observed.RESULTS AND CONCLUSION:All 17 patients showed no rejection,and the wound healing well at the primary stage.At 6,12,24 after operation,all patients were followed-up.According to AOFAS criteria,function of ankle in all patients was significantly improved.No patients complained of instability of the ankle,end stress radiograph confirmed this improvement.Reconstruction of lateral ligaments of the ankle with allogeneic tendon and anchors is a practical treatment,which restores stability and function of ankle without long incision or damaging normal tendons.

OBJECTIVETo explore the correlation between electronic bronchus mirror and Chinese medical syndrome typing of Mycoplasma pneumonia children.

METHODSTotally 198 Mycoplasma pneumonia children inpatients were assigned to three syndrome types according to Chinese medical syndrome typing and self-formulated typing standards of electronic bronchus mirror, i.e., Fei-qi accumulation of damp and heat syndrome, Fei-qi accumulation of toxicity and heat syndrome, deficient vital qi leading to lingering of pathogen syndrome. The correlation between electronic bronchus mirror and Chinese medical syndrome typing was explored.

Objective To compare the value of speckle-tracking imaging and tissue Doppler strain imaging in evaluating left atrial (LA) mechanical contraction. Methods Forty patients after successful percutaneous atrial septal defect (ASD) closure were enrolled in this study. Two-dimensional strain imaging (2D strain echocardiography, 2DSE) and tissue Doppler imaging (TDI) were performed one weak after ASD closure. Off-line analysis was done for atrial longitudinal peak systolic strain on the interatrial septum, in correspondence of the device, and on the lateral wall of the left atrium from apical 4 chamber view with 2DSE and color-coded strain imaging, respectively. Results There was no statistical difference of the inter- and intra-observer viability as well as time consumption on the off-line analysis between 2DSE and TDI. LA lateral wall strain was much higher than that of LA septum assessed by both color-coded strain imaging (47.31%±27.25% vs 30.06%±14.29%, P<0.01) and 2DSE (43.49%±25.55% vs 12.74%±9.16%, P<0.001). LA lateral wall strain was similar with either method (P=NS). However, at the site of ASD occluder, a non-contractile element, deformation was significantly higher in color-coded strain imaging than 2DSE (P<0.001). Five patients (12.50%) presented absence of deformation on ASD occluder with 2DSE, whereas there was no patient with TDI assessment (χ~2=5.33, P=0.027). Conclusion Speckle-tracking imaging is superior to tissue Doppler strain imaging in assessing left atrium mechanical function.

Objective To investigate the relation between the expression of Caspase recruitment domain-containing membrane-associated guanylate kinase protein 1 (CARMA1),clinicopathological features of gastrointestinal mucosa-associated lymphoid tissue (MALT) lymphoma,diffuse large B cell lymphoma (DLBCL),and Helicobacter pylori (H.pylori) infection.Methods From January 1999 to March 2011,34 patients with DLBCL and 20 patients with MALT lymphoma were selected,and at same period 21 cases with reactive hyperplasia of gastrointestinal lymphoid tissue were enrolled in as control.The expression of CARMA1,Ki-67 and cytotoxin-associated gene A (CagA) at protein level were examined by immunohistochemistry.The relative expression quantity of CARMA1 mRNA was detected by real-time polymerase chain reaction (PCR).The condition of H.pylori infection in 25 gastric lymphoma and 10 controls was detected by methylene boric acid and blue staining or semi-nested PCR.Chi-square test was used for counting data analysis,t test for measurement data.Multivariate COX regression analysis was implemented for survival analysis.Survival curve was drawn by Kaplan-Meier method and analyzed by Log-rank test.Results The relative expression quantity of CARMA1 mRNA of 28 patients with DLBLC (3.073±1.846) was higher than that of 14 patients with MALT lymphoma,and the difference was statistically significant (F 0.975,P＜ 0.05).The positive rate of CARMA1 expression at protein level of gastrointestinal lymphoma group (75.9 ％,41/54) was higher than that of control group (47.6％,10/21),and the difference was statistically significant (x2 =5.568,P＜0.05),and the positive rate of CARMA1 expression of MALT lymphoma group (11/20) was lower than that of DLBCL group (88.2％,30/34),and the difference was statistically significant (x2 =5.900,P＜0.05).Among 42 patients with gastrointestinal lymphoma who received surgery,the relative expression quantity of CARMA1 mRNA in cases with high proliferation (2.885±1.837) was higher than that in cases with low proliferation.The expression of CARMA1 mRNA in the cases at advanced stage of the disease (4.416± 1.010) was higher than that in cases at early stage,and the difference was statistically significant (F=3.317 and 2.972,both P＜0.05).Among 54 patients with gastrointestinal lymphoma,the positive rate of CARMA1 expression at protein level of patients with high proliferation (88.6％,31/35) was higher that that of patients with low proliferation (10/19),and the difference was statistically significant (x22 ＝ 6.847,P＜0.05).There were no significant differences in relative expression quantity of CARMA1 mRNA and the positive rate of CARMA1 expression at protein level between 11 gastric lymphoma patients without H.pylori infection and 14 gastric lymphoma patients with H.pylori infection (both P＞0.05).The positive rate of CARMA1 expression at protein level of CagA positive and CagA negative H.pylori infected gastric lymphoma patients was 11/11 and 2/3.The expression of CARMA1 at protein level was correlated with the prognosis of gastrointestinal lymphoma (RR＝4.160,P＜0.05).In the 29 cases of patients with gastrointestinal MALT lymphoma and 18 cases of patients with DLBCL who were followed up,the survival situation of gastrointestinal lymphoma patients with CARMA1 positive expression rate over 50％ was worse than that of patients with the rate less than 50％,and the difference was statistically significant (x2=5.383 and 4.028,both P＜0.05).Conclusions CARMA1 might be involved in the pathogenesis and progression of MALT and DLBCL; and it might be a related factor of poor prognosis.There was no correlation between the expression of CARMA1 and H.pylori infection in these two lymphomas.
