Objective: To investigate the expression of zinc finger protein 262 (ZNF262) mRNA in normal kidney tissues and kidney tissues of patients with autosomal-dominant polycystic kidney disease (ADPKD) at different stages, and to explore the role of ZNF262 in pathogenesis of ADPKD. Methods: Patients with ADPKD were staged according to glomerular filter rate (GFR). Imaging observation and routine pathological examination were performed. The expression of ZNF262 mRNA and proliferating cell nuclear antigen (PCNA) mRNA in normal kidney tissues (n=8), early stage ADPKD kidney tissues (n=4) and advanced stage ADPKD kidney tissues (n=4) was examined by semi-quantitative RT-PCR. The correlation between the expressions of the 2 genes was investigated in all tissue specimens. Results: Expression of ZNF262 mRNA and PCNA mRNA in early and advanced ADPKD kidney tissues was significantly higher than that in normal renal tissues (both P<0.01), and that in the advanced stage ADPKD was significantly higher than that in early stage ADPKD (both P<0.05). The expression of ZNF262 and PCNA mRNA was highly correlated in the early, advanced ADPKD and normal renal tissues(r1 =0.842 6, r2=0.902 1 and r3=0.883 5, respectively, all P<0.05). Conclusion: The ZNF262 mRNA lev el is higher in ADPKD kidney tissue than that in normal control and increases with the advancement of ADPKD. The expression of ZNF262 is significantly correlated with the expression of PCNA in the same renal tissues. The expression of ZNF262 mRNA may serve as an indicator in diagnosis of ADPKD and may be used for clinical staging of ADPKD patients.

OBJECTIVETo compare the differences in pain reaction, hemodynamics and clinical efficacy between extracorporeal shock wave lithotripsy (ESWL) after injection with flurphen mixture (mixture of droperidol and fentanyl citrate) at Shenshu (BL 23) and simple ESWL in the patients.

METHODSSixty-four cases of urinary calculi with ESWL were randomized into an observation group and a control group, 32 cases in each one. In the observation group, 15 to 20 min before ESWL, flurphen mixture (droperidol injection 1.25 mg and fentanyl citrate injection 0.05 mg were diluted to 6 mL with 0.9% sodium chloride solution 4.5 mL) was injected at bilateral Shenshu (BL 23). In the control group, no any adjuvant therapy and medication were used before ESWL. The changes in blood pressure and heart rate, visual analogue scale (VAS) score, lithotripsy frequency till calculi complete removal and the rate of calculi complete removal after the first lithotripsy were observed in the two groups.

RESULTSIn the control group, blood pressure and heart rate were higher during lithotripsy than those before lithotripsy (both P<0.05). In the observation group, the differences in blood pressure and heart rate were not significant statistically as compared with those before lithotripsy (both P>0.05). The blood pressure and heart rate during lithotripsy in the observation group were apparently lower than those in the control group (both P<0.05). VAS scores during lithotripsy in the observation group were lower apparently than those in the control group (both P<0.05). The lithotripsy frequency in the observation group was less than that in the control group. The rate of calculi complete removal in 1 week after the first lithotripsy in the observation group was higher than that in the control group [75.0% (24/32) vs 50.0% (16/32), P<0.05].

CONCLUSIONThe flurphen mixture at Shenshu (BL 23) significantly alleviates pain reaction in patients undergoing ESWL, avoids the fluctuation of hemodynamics and improves the clinical effect of lithotripsy.

Background Toll-like receptor 4 (TLR4) is an immune related receptor.It plays an important role in inducing inflammation response.The inflammatory response secondary to optic nerve crush will results in serious retinal damage.It is worthy of studying the expression and effect of TLR4 in retina after optic nerve crush.Objective This experimental study was to explore the role of TLR4 in the loss of retinal ganglion cells(RGCs) after optic nerve crush.Methods Twenty-four SPF adult health Sprague-Dawley (SD) rats were used in the study and radomized into two groups based to the experimental time.The optical nerve crush models were established by crushing the optical nerve in the right eyes of the rats,and the left normal eyes served as controls.The rats were sacrificed by over anesthesia and retinas were isolated 3 days and 7 days after operation.Expression of TLR4 in the retinas was detected using immunofluorescence method.Reverse trancription PCR (RT-PCR) and Western blot were applied respectively for the detection of TLR4 mRNA and protein in the retinas.The apoptosis of RGCs was evaluated using TUNEL staining.The use and care of experimental animals followed theGuide for the Care and Use of Laboratory Animals of NIH.This study was approved by the Institutional Animal Care and Use Committee at the Zhongshan Ophthalmic Center.Results The expression of TLR4 in rat retinas presented with green fluorescence mainly in the inner layer of retinas.The fluorescence was enhanced in the model 3 days group and the model 7 days group compared with the corresponding control groups.The relative expressing values of TLR4 mRNA in the retinas were 2.92±0.06and 3.92±0.12 in the model 3 days and 7 days groups,respectively,which were significantly higher than 2.87±0.12and 3.44±0.17 in the control 3 days and 7 days group (t3d =-12.888,P＜0.001 ;t7d =-4.669,P=0.010).In the model 3 days group and model 7 days group,the grey values of TLR4 protein were 1.14±0.05 and 1.49±0.03,and those in the control 3 days and 7 days groups were 0.99 ± 0.09 and 1.38 ± 0.07,showing significant differences between them(t3d =-11.324,P＜0.001 ;t7d =-5.638,P=0.005).Apoptotic RGCs were obviously increased in the optic nerve damage group in comparison with the control group.Conclusions The TLR4 is over-expressed in the inner layer of retina after optic nerve crush,which suggestes that TLR4 is probably involved in the loss of RGCs after optic nerve crush.

Objective To investigate the clinical efficacy of anterior pelvic plating plus percutaneous lumbo-iliac rod/screw fixation in the treatment of pelvic fractures which are vertically and rotationally unstable and combined with unilateral sacral fracture of Denis type Ⅱ.Methods From January 2008 to November 2012,19 patients were treated for compound injury to the anterior and posterior pelvic rings complicated with sacral fracture of unilateral Denis type Ⅱ using anterior pelvic plating plus posterior percutaneous fixation of lumbo-ilium with screws.Their improvement in neurological function,reduction outcome and clinical effectiveness were evaluated by comparing preoperation and 2 years postoperation in terms of visual analogue scale (VAS),Japanese Orthopaedic Association (JOA) score for lower back pain,MOS Item Short-form health survey (SF-36 comprehensive scale),modified Roland-Morris Disability questionnaire (RDQ),Oswestry disability index (ODI),Gibbons overall scale,Majeed total score,sacral kyphosis abnormity,bias of sagittal/coronal vertical axis (SVA/CVA),pelvic incidence,pelvic tilt,lumbar lordosis,vertical displace,and leg length discrepancy.Results The differences respectively reached statistical significance for the aforementioned clinical and imaging parameters between preoperation and 2 years postoperation (P ＜ 0.05).By Majeed scoring,13 cases were rated as excellent,4 as good and 2 as fair.By Tometta/Matto scoring postoperatively,the fracture reduction was rated as excellent in 12 cases,as good in 6 and as fair in one.The complications of incision infection or necrosis,secondary neurovascular damage,implant failure or mal-union was not observed.Perfect nerve functional recovery and sufficient imaging reduction were achieved in all but one patient who had to receive decompression and release for sacral canals or foramens.According to Mohammad criteria,15 patients were engaged in the jobs with the same intensity and property as their pre-injury ones.Conclusions The simultaneous hybrid performance of anterior reconstruction plating combined with unilateral lumbar/sacral pedicle and iliac screwing may be a safe,reliable and satisfactory treatment for pelvic fractures of AO/Tile C1 type which involve unilateral sacral Denis type Ⅱ.

Objective To investigatethe clinical value of troponin-I(cTnI)in patientswith septic shocka-nd left ventricular diastolic dysfunction. Methods As a retrospective analysis ,38 patients with left ventricular di-astolic dysfunction and septic shock(Sa group),as well as 20 patients with normal cardiac function(Sn group) were enrolled in this study. Moreover ,20 patients with left ventricular diastolic dysfunction and without septic shock were used as control group(Ca group). The ratio of early diastolic mitral inflow velocity to early diastolic mi-tral annulus velocity(E/e′)was measured as the evaluation index of left ventricular diastolicfunction by echocar-diography within 72 hours after admission to ICU. Level of cTnI was detected in all cases and the relationship was evaluated by E/e′. Receiver operating characteristic curve(ROC)was constructed to indicate the predictable value of left ventricular diastolic dysfunction in patients with septic shock. Results The level of cTnI was significantly elevated in both Sa group and Sn group(P<0.05),while the level of cTnI and E/e′in Sa group were significantly higher than those in Sn group(P < 0.05). cTnI was positively correlated with E/e′(r = 0.367 ,P = 0.004). The area under the curve(AUC)of cTnI was 0.834,with the cut-off value of 0.49 ng/mL(sensibility=77.6,specificity=80.7). Conclusion The level of cTnI was significantly higher in patients with septic shock. cTnI was significantly correlated to left ventricular diastolic dysfunction in patients with septic shock. cTnI ≥ 0.49 ng/mL could be an available predictor for left ventricular diastolic dysfunction in patients with septic shock.

Objective To observe the influence of Lycium Barbarum polysaccharide(LBP) on FasL expression in H22-bearing mice and to explore its anti-tumor mechanism.Methods Kunming mice were randomized into the model group,and low-and high-dose LBP(in the dose of 0.625 and 1.250 g?kg-1?d-1 respectively) groups.H22-bearing mice models were induced through right subaxillary inoculation of H22-ascitic cells.Three days after inoculation,LBP group were given LBP for 14 days.Hematoxylin and eosin(HE) staining method was used to examine the tumor cell density,tumor cell mitotic count,and lymphocyte infiltration in tumor interstitial tissue.FasL expression was observed in the three groups with immunohistochemical method.Results Tumor cell mitotic count was decreased in the two LBP groups(P

Objective To investigate the possibility and accuracy of predicting malignant middle cerebral artery infarction (mMCAI) with bedside electroencephalography (EEG). Methods Thirty-five patients with massive hemispheric infarction (MHI) underwent bedside EEG monitoring within 48 h of onset. The EEG indicators were interpreted blindly, and the clinical, laboratory and imaging parameters were analyzed. The patients were divided into mMCAI group and non-mMCAI group according to whether they had occurred mMCAI or not within 7 days of onset. The differences of EEG indicators, clinical, laboratory and imaging parameters between the 2 groups were compared. When the parameters of significant difference and statistical significance appeared the odds ratio (OR) of occurring mMCAI were analyzed, and their accuracy of predicting mMCAI was calculated. Results Of the 35 patients with MHI, 20 were in the mMCAI group and 15 were in the non-mMCAI group. There were significant differences in the EEG indicators (infarction on the contralateral side, including disintegration of occipital α rhythm, generalized slow-wave, dominant frequency wave low amplitude, regional attenuation without delta [RAWOD]pattern, and absence of EEG reactivity), clinical parameters (nausea accompanied with vomiting), and imaging parameters (the infracted area more than the entire MCA territory, and midline shifting 3 to 5 mm at the level of septum pellucidum) between the 2 groups (P < 0. 05). Of those, the risk of mMCAI was the highest in patients with disintegration of occipital a rhythm on the contralateral side of infarction (P = 22. 67, 95% CI 3. 89-132. 10). The sensitivity of predicting mMCAI was 85. 0%, the specificity was 80.0%, the positive predictive value was 85.0%, and the negative predictive value was 80. 0%, which were superior to other EEG indicators and clinical or imaging parameters. Conclusions Bedside EEG indicators can early predict mMCAI, moreover, the predictive accuracy is superior to the clinical and imaging parameters.
