Objective To discuss fluvastatin intervention on ventricular remodeling and plasma brain natri-uretic peptide( BNP) levels in dilated cardiomyopathy( DCM) .Methods 64 cases of DCM patients were selected and randomly divided into the intervention group and control group,each group in 32 cases.Both groups were treated with conventional drug therapy, including angiotensin-converting enzyme inhibitors,β-blockers, diuretics, etc.In conven-tional drug treatment intervention group based on the use of fluvastatin 40mg/d.Intervention in both groups before and 6 months after the intervention,plasma BNP levels were examined and ventricular remodeling indicators,analyzed and compared using Pearson Univariate correlation of each index.Results The total efficiency of the intervention group was higher than that of the control group(87.51%vs 65.63%,χ2 =4.730,P<0.05);6 months after the interven-tion groups,plasma BNP levels were significantly decreased left ventricular ejection fraction(LVEF),left ventricular end systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD) and relative wall thickness(RWT) were significantly improvements.BNP levels and LVEF and RWT was negatively correlated( r=-0.45,-0.39,all P<0.05);Positively correlated with LVESD and LVEDD showed(r=0.35,0.44,all P<0.05),the difference was statistically significant.Conclusion Fluvastatin intervention can significantly reduce plasma BNP levels in DCM and improve ventricular remodeling.

Objective To assess the outcomes of modified spiral ileal orthotopic neobladder.Methods From January 1998 to January 2008, 32 patients (all male) underwent radical cystectomy and spiral ileal orthotopic substitution for muscle invasive bladder cancer. A segment of 40 to 45 cm ileal loop was isolated, detubularized, and reconfigured in spiral shape to form a pouch. Bilateral ureters were reimplanted by inserting the 1 cm distal segment into the pouch to form a Split-Cuff nipple.The bottom of the pouch was opened and anastomosed with the urethra (4 stitches). Results There were no perioperative deaths. The mean operative time was 281.2±48.7 min. Blood loss was 545.4±181.9 ml. Twenty cases required a blood transfusion, the mean volume of intraoprative blood transfusion was 430.8±235.9 ml. The average hospital stays were 26.8±9. 7 days. Rate of daytime continence was 93. 7% (30/32) while nighttime continence was 81.3% (26/32). Urodynamic studies were carried out in 23 cases 6 months after surgery. Neobladder capacity at first desire to urinate was 315.0± 33.4 ml(270-420 ml). The maximum neobladder capacity was 490. 3±39.7 ml(350-600 ml).The maximum flow rate (Qmax) was 16.5 ± 5.9 ml/s. Full resting pressure was 22. 5 ± 11.8 cm H2O. Peak voiding pressure was 78.3 ± 14.7 cm H2O. After mean 58. 4 months' follow up (range 22 to 132), 4 cases died of metastasis of bladder cancer. Conclusion Modified spiral ileal orthotopic neobladder is a reasonable option for treating invasive bladder cancer.

Background Increase of lens thickness at incipient cataract is a key factor of onset of primary angle-closure glaucoma (PACG).Phacoemulsification (Phaco) or phacotrabeculectomy (Phacotrabe) have been documented to be effective for the patients of PACG associated with cataract.However,which surgery is more effective and safe is lack of evidence.Objective This study was to assess and compare the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract.Methods The relevant literature was searched electronically from the PubMed (1966 to June 2011),EMB Reviews (1966 to June 2011) and Cochrane Library (Issue 1,2011).The manually searching of relevant conference proceedings was used as the supplement.The articles of randomized controlled trial (RCT) about the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract were included.The methodology quality of included literature was graded.The analysis indexes included intraocular pressure (IOP)-lowing range,postoperative administration of glaucoma drugs,incidence of positive complication,postoperative best corrective visual acuity (BCVA) and perimetry damage.The RevMan4.2 software from Cochrane Collaboration was used for the Meta analyses.Results Three RCTs about phaco versus Phacotrabe for PACG with cataract were selected in this study with the 164 eyes of 164 cases.Meta analysis showed that the IOP-lowing range was larger in the Phacotrabe group compared to only Phaco group with the WMD of 1.17 and 95％ CI of 0.06-2.27 (P =0.040),and the drug dosage of anti-glaucoma was less in the Phacotrabe group in comparison with the Phaco group with the WMD of 0.5 and 95％ CI of 0.24-0.77 (P =0.000).However,the incidence of postoperative complication was higher in the Phacotrabe group than that of the Phaco group with the RR of 0.08 and 95％ CI of 0.02-0.33 (P =0.000).No significant difference was found in the BCVA (WMD =0,95％ CI:-0.13-0.13,P=1.00) andperimetry (WMD =1.01,95％CI:0.56-1.82,P=0.98).Conclusions Compared with Phaco,Phacotrab has a better IOP-lowing effectiveness and slightly worse safety.Phaco and Phacotrab have a fairly influencc in the postoperative BCVA and perimetry.As the sample sizes of the included trials are relatively small,more welldesigned large-scale RCTs are needed.

AIM:To observe the transplantation of acellular porcine corneal stroma on the treatment of superficial keratitis by drug-resistant fungal.METHODS:We performed a retrospective analysis of 16 cases of fungal keratitis received the transplantation of acellular porcine corneal matrix from June 2015 to March 2016 with a follow-up of 6mo.We analyzed on items as postoperative visual acuity, corneal graft status, postoperative recurrence and postoperative complications.RESULTS:We observed a healing time of corneal epithelium in 7 to 10d postoperatively generally and the absence of corneal edema in 1mo, while the cornea gradually returned transparent in the 16 cases.Two cases required medication for an epithelial recovery and 3 cases received intervention for decreasing intraocular pressure to a certain level.During the follow-up we observed no cases of cornea degeneration, recurrence of infection or rejection.The vision acuity showed 1.27±0.22, 1.11±0.13, 0.79±0.22 in 1, 3 and 6mo after operation respectively.There was no statistical difference between vision in 1mo and the vision before surgery (P=0.06);while we found a statistical difference when comparing the vision of 3 and 6mo with vision before surgery (P=0.01,0.001).The vision in 6mo increased with a statistic difference to the vision at 1 and 3mo (P<0.001) while no statistic difference was observed between 1 and 3mo(P=0.11).CONCLUSION:Transplantation of acellular porcine corneal matrix is a safe and efficient treatment for fungal keratitis.

Objective To study the state of erythrocyte immune function in neonates with hyperbilirubinemia,and analyze the influence of various clinical status on erythrocyte immune function.Methods Fifty-two neonates with hyperbilirubinemia were enrolled and 104 healthy neonates as the control group.The adherence rate of complement 3b-receptor on the surface of red blood cell(RBC-C3bRR) and the immune complex adherence rate of red blood cell(RBC-ICR) were detected with erythrocyte saccha-romycete rosettet test.Results 1.The level of RBC-C3bRR in neonates with hyperbilirubinemia was lower than that in control group,and the level of RBC-ICR in neonates with hyperbilirubinemia was higher than that of control group(Pa0.05).3.Comparing the neonates with unconjugated bilirubin of different concentrations,there were significant difference in RBC-ICR(Pa0.05).4.There were positive correlation between RBC-ICR and bilirubin,unconjugated bilirubin in the neonates(Pa0.05).Conclusion Erythrocyte immune function in neonates with hyperbilirubinemia is obviously lower than that of control group and it is influenced by the concentratron of bilirubin and the time of phototherapy.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Objective:To explore the central neurobiological mechanisms of pleasure effect on rats with neuralgia treated by tuina manipulations of An-pressing and Rou-kneading Huantiao (GB 30).Methods:A total of 64 male Sprague-Dawley (SD) rats were used in this study.Eighteen rats were randomly selected as a normal group,and the other 46 rats were used to duplicate the chronic constriction injury (CCI) model.Ten rats failed in modeling and 36 rats succeeded.These 36 rats were then randomly divided into a model group and a tuina group,with 18 rats in each group.The rats in the normal group and the model group did not receive any interventions,while those in the tuina group received An-pressing and Rou-kneading Huantiao (GB 30),1 min for each time,once a day,3 weeks in total.Heating tests were evaluated to observe the change of pain-sensitivity score before intervention,1 week after intervention,2 weeks after intervention,and 3 weeks after intervention.After 1 week of intervention,2 weeks of intervention,and 3 weeks of intervention,6 rats were randomly selected from each group respectively for brain extraction.The change of Nissl's body and β-endorphin in the accumbens nucleus as well as amygdaloid nucleus of pleasure circuits,and pro-opiomelanocortin (POMC) in the arcuate nucleus were analyzed by methods of histochemistry and molecular biology.Results:After modeling,the pain-sensitivity scores of the tuina group and the model group were statistically different from the score of the normal group (both P＜0.05).After An-pressing and Rou-kneading Huantiao (GB 30) for one week,the pain-sensitivity score of the tuina group had statistical difference compared with that of the model group (P＜0.05).At each different time point:the amounts of Nissl's body in accumbens nucleus and amygdaloid nucleus of the tuina group were significantly more than those of the model group (all P＜0.01).Besides,the numbers of β-endorphin immunoreactive cells in the accumbens nucleus and amygdaloid nucleus of the rats in the tuina group were significantly higher than those in the model group (all P＜0.01),and so was the expression of POMC in arcuate nucleus (all P＜0.01).Conclusion:An-pressing and Rou-kneading Huantiao (GB 30),where the sciatic nerve is ligated,can reduce pain-sensitivity score and increase pain tolerance value of rats with chronic neuralgia.It can increase the activity of neurons in accumbens nucleus and amygdaloid nucleus of pleasure circuits,which indicates that the analgesia effect of tuina therapy may correlate with pleasure effect,and also reveals a part of neurobiological mechanisms of neuralgia.

Objective To investigate the clinical and mammographic features of plasma cell mastitis.Methods Twenty-five patients(28 lesions)with histologically confirmed plasma cell mastitis, aged from 26 to 70 years(mean age 41 years),were examined with X-ray mammography.The clinical manifestations and imaging features were retrospectively reviewed.Results No case was in lactation.The painful irregular masses,ranged from 1.3 to 8cm in size,were found in 22 patients,while 3 patients with acute episode.Recurrent episodes of breast masses were noted in 4 patients.Based on the mammographic appearances,the plasma cell mastitis were classified as the following four types:inflammation-like type (2/28),ductal ectasia type(3/28),focal infiltration type(10/28)and nodular type(13/28).The valuable radiogyaphic signs:(1)An asymmetrically increased density along the lactiferous duct with a flame-like appearance,inhomogeneous low density tubular structures and scattered stick-shape calcifications.(2) Architectural distortion and oil cysts formation in adjacent area,(3)Subareolar ductal ectasia.Conclusions The clinical and mammographic characteristics of plasma cell mastitis are critical to avoiding unnecessary surgery.Histopathological result is needed for the diagnosis in patients highly suspected of malignancy.

Objective To explore the relationship of c-fos protein and cell apoptosis by observing the expression of c-fos protein in hippocampus of newborn rat with hypoxic-ischemic brain damage(HIBD).Methods Forty-eight 7-day SD neonatal rats were randomly divided into control group(n=6) and experiment group(n=42).The models of HIBD were established in neonatal rats by inhaling the mixed gases of 920 mL/L N2 and 80 mL/L O2,and the animals were sacrificed by dislocation their heads at different time points(0.5,1,3,6,12,24,48,72 h),then the hippocampus were dissected by morphological analysis.Results The apoptotic cells appeared at the time point of 3 h,and reached the peak at 48 h,then decreased.The positive cell of c-fos protein increased from the time point of 30 min and reached the peak at 2 h and then decreased gradually,and there was a contrary tendency between the expression of c-fos protein and the number of damaged brain cells by HIBD(r=-0.57 P

Objective To explore the effect of intrauterin hypoxia on proliferation of neural stem cells(NSCs)in dentate gyrus of juve-nile rats and the interventive effects on NSCs.Methods Thirty-nine adult female SD rats bred at laboratory.At 14 days of pregnancy,conceiving female SD rats were randomly divided into 3 groups:control group(n=12),hypoxia group(n=12)and angelica group(n=15);the conceiving rats were put into 3 gases incubator(130 mL/L O2,temperature 25 ℃,relative humidity 70%-75%,CO2 0.3-0.4 mL/L),hypoxia times(2 h/d),hypoxia days(pregnant the 14th d,15th d,16th d)to make intrauterin hypoxia model.In hypoxia group,1 hour before hypoxia,the rats were injected saline from caudal vein,saline for 7 days;In angelica group,the rats were injected angelica injection,angelica for 7 days,other steps were same.In control group,the rats were injected saline,saline for 7 days,no hypoxia.Producing naturally,after born 40 days,took juvenile rats' brains from every group randomly:control group(n=12),hypoxia group(n=12)and angelica group(n=15),then immobilization,paraffin imbedding,slicing,common immunohistochemistry staining were used to detect the Nestin positive substances.Nestin positive substances expression were observed under the microscope(?200).Statistical analysis was used.Results The average of positive staining area(Area)of Nestin of hypoxic group were larger than that of control group,it had significance(P0.05),the average of density and IOD of 3 groups had no significances.Conclusion Hypoxia environment(130 mL/L)can promote NSCs of juvenile rats to proliferate,angelica injection can reduce the NSCs to proliferate after intrauterin hypoxia.
