Objective To investigate the emergency treatment and correlation factors of aqueous misdirection during glaucoma and cataract surgery in glaucoma patients.Design Retrospective case series.Participants 126 cases(132 eyes)of angle-closure glaucoma patients with aqueous misdirection during surgery,100 cases(100 eyes)of angle-closure glaucoma patients without aqueous misdirection during surgery and 100 cases(100 eyes)of senile cataract patients.Methods We performed pars plana vitreous water-bag aspiration or anterior vitrectomy on glaucoma patients with aqueous misdirection during surgery.All the factors in observation group and control groups were compared and analyzed by logistic regression.Main Outcome Measures Preoperative highest intraocular pressure(HIOP),intraocular pressure after maximum dose(IOP),anterior chamber depth(ACD),lens thickness(LENS),axial length (AXL),mean keratometry(K),intraocular lens diopter within-0.5D corrected by SRK-T formula(IOLD).Results Among all the 132 angle-closure glaucoma eyes whose posterior chamber pressures were increased during surgery,we performed pars plana vitreous water-bag aspiration in 123 eyes(93.18%),and anterior vitrectomy in 9 eyes(6.8%).Postoperative complications included shallow anterior chamber in 20 eyes(7 eyes with malignant glaucoma,9 eyes with choroidal detachment,4 eyes with delayed local suprachorodal hemorrhage),and vitreous local hemorrhage in 1 eye.Means of all the observation indexes on three groups showed significant difference(all P

Objective To explore the effect of spinal decompression system on lumbar disc herniation. Methods 83 patients of lumbar disc herniation were divided into observation group (n=42) and control group (n=41). Both groups received massage therapy, while the observation group was treated with spinal decompression system in addition. The effect was evaluated with Visual Analogue Scale (VAS) and Japanese Orthopedic Association (JOA) assessment of low back pain. Results The VAS score decreased and the JOA score increased in both groups after treatment (P<0.05), and it was better in the observation group than in the control group (P<0.01). Conclusion Spinal decompression system could improve the therapeutic effect on lumbar disc herniation.

How to remove the well fixed cement or cementless prosthesis and get a completely distal cement removal in the rTHR are critical to the outcome of revision. Because of higher rate of union, excellent intraoperative exposure, and adjustment of abductor tension, ETO has been widely applied to rTHR and complicated primary THR by foreign scholars. Furthermore, this technology has wide indications, very few contraindications, high cure rates,and low complications rate. ETO turns out to be a safe and effective revision technology. In the article, the indication, contraindication, complications and advantages of this technique were reviewed.

Objective To explore the function and significance of caudal type homeobox transcription factor-2 (CDX)-2,heparin-binding epidermal growth factor-like growth factor (HB-EGF) and bone morphogenetic protein 4 (BMP-4) of esophageal stromal tissues in the pathogenesis of Barrett's esophagus (BE).Methods A total of 116 patients were divided into groups according to gastroscopic finds and hematoxylin-eosin (H &E) staining of biopsy samples.They were divided into control group (n=29),RE group (n=32),BE group (n=35),RE treatment group (n=10) and BE treatment group (n=10).The expression of CDX 2,HB-EGF and BMP-4 in different esophageal mucosal lesions was detected by immunohistochemical staining and the changes of positive expression levels of CDX-2,HBEGF and BMP 4 were compared among groups.Variance analysis and chi-square analysis were performed to analyze the correlation among the three factors.Results The CDX-2 positive cell number of control group ((0.0±0.0)/high power field(HPF)),RE group ((43.1±10.6)/HPF),and BE group ((67.8±11.3)/HPF) increased in turn,and the differences among three groups were statistically significant (F=67.664,P＜0.01).The HBEGF positive ((6.4±1.4)/HPF,(39.4±13.5)/HPF,(55.8±13.9)/HPF) and BMP 4 positive ((0.0±0.0)/HPF,(22.6±6.4)/HPF and ((25.1± 10.3)/HPF) cell number of three groups had the same trend and the differences among three groups were statistically significant (F HB-EGF =22.925,FBMP-4 =10.463,both P＜0.01).Except the expression of BMP-4 between RE group and BE group,there were significant differences between every other two groups (LSD test,all P＜ 0.01).The expression of CDX 2,HB EGF,BMP-4 in RE treatment group ((21.7±1.7)/HPF,(16.6±5.0)/HPF and (9.2±1.0)/HPF) and BE treatment group ((51.4±8.7)/HPF,(31.0± 10.4)/HPF and (12.7±3.9)/HPF) were lower than those in RE group and BE group respectively,the differences were also statistically significant (LSD test,all P＜0.05).In RE group,the positive rate of CDX-2 (31.2％ (10/32)) was significantly lower than that of HBEGF and BMP4 (62.5％ (20/32) and 56.2％(18/32)),and the differences were statistically significant (x2=6.275 and 4.063,both P＜0.05).However in BE group,there was no statistically significant difference in the positive rate among CDX-2(85.7％(30/35)),HB-EGF (88.6％(31/35)) and BMP-4 (74.3％(26/35),all P＞0.05).Conclusions CDX-2,HB-EGF and BMP-4 may play an important role in the pathogenesis of RE and BE.HB-EGF and BMP-4 may be involved in the early episodes of BE genesis and have promotion effects on CDX-2 expression.HB-EGF and BMP-4 may be the new target in the research and treatment of BE.

Objective To evaluate the efficacy of entecavir treatment on hepatitis B patients with acute-on-chronic liver failure. Methods Eighty-four hepatitis B patients with acute-on-chronic liver failure were treated with entecavir 0.5 mg daily and Other routine drugs. Another 99 hepatitis B patients with acute-on-chronic liver failure were treated with only routine drugs as control. The survival, liver functions, hepatitis B virus (HBV) DNA level, prothrombin time (PT) were observed. The survival rates of patients with early, middle or late stage of liver failure were analyzed. The comparison of rates were done using chi-square test. The numeration data were compared by t test. The survival rates were compared using Kaplan-Meier method. Results Among patients with early stage of acute-on-chronic liver failure, the survival rate in treatment group was 63.3% (31/49), which was significantly higher than that in control group (39.7%, 23/58) (χ2=5.923, P=0.015). Among patients with middle stage of acute-on-chronic liver failure, the surviral rate in treatment group was 63.0% (17/27), which was significantly higher than that in control group (35.1%, 13/37) (χ2=4.854, P=0.028). Among patients with late stage of acute-on-chronic liver failure, four out of eight cases survived in treatment group, while one out of four cases survived in control group. In patients with serum total hilirubin (TBil) level > 342 μmol/L, the survival rate was 56.0% in treatment group, which was significantly higher than that in control group (26.8%) (χ2=9.351,P=0.002). At week 4 of the treatment, the HBV DNA reduction in treatment group was 3. 95 lg copy/mL, which was higher than that in control group (1.78 lg copy/mL) (t=5.847, P=0.001). Conclusions Entecavir treatment could improve the survival rate of hepatitis B patients with early or middle stage of acute-on-chronic liver failure. And the further study with larger population is needed in patients with late stage of liver failure. In addition, entecavir therapy could also improve the survival rate of patients with TBil >342 μmol/L.

Objective:To compare the biomechanical effects between oblique Ban-pulling manipulation and lumbar erection-rotation manipulation in sitting position in treating lumbar intervertebral disc herniation (LIDH). Methods:A three-dimensional finite element model of L3-S1 was developed to carry out a comparative study between oblique Ban-pulling manipulation and lumbar erection and rotation manipulation in sitting position. The disc protrusion was assumed to be on the rear left of L4 disc, and the manipulations were performed on the right side. The loading process was simulated by two steps. In the first step, only the compression loading was imposed, and in the second step, both the compression loading and axial rotation moment were imposed. The displacement and stress distribution in L4 disc were investigated. Results:The values of stress and displacement in the second step were lower than those in the first step in each manipulation. The stress and displacement differences between the two steps were respectively 1.79 times and 3.03 times larger in oblique Ban-pulling manipulation than those in lumbar erection-rotation manipulation in sitting position. Conclusion: Oblique Ban-pulling manipulation may result in a better biomechanical effect than lumbar erection-rotation manipulation in sitting position for LIDH.
