Objective To evaluate the alteration of labial bone mass one year after immediate implant or delayed implant placement in esthetic zone.Methods From June 2009 to June 2012,22 patients with 11 immediate implant and 11 delayed implant in the maxillary anterior region were followed up.CBCT images were obtained immediately after surgery and one year after implant placement,the horizontal and vertical alterations of the labial bone were evaluated by image analysis software.Results The 1-year vertical reduction of labial bone after immediate implant placement was statistically significant (P＜0.05),and no significant difference in delayed implant (P＞0.05).The 1-year horizontal reduction of labial bone was statistically significant at coronal and middle of implant,without significant difference at apical of implant.Conclusions Immediate implant can not stop the physical absorption of labial alveolar ridge,and the study can provide reference to achieve esthetics in the anterior region.

BACKGROUND:As the rapid development of oral implantation and restoration techniques, as wel as the increasing enlargement of indications, angulated abutments have been widely used. Posterior teeth region, as the weight-loading region of occlusion, can bear great force from the implants, the assessment of angulated abutments in posterior teeth region has clinical value.
OBJECTIVE:To evaluate the short-term clinical efficacy of angulated abutments on the implant denture in posterior teeth region.
METHODS:From January 2008 to January 2013, 114 patients with 175 ITI implants in the posterior teeth region were included in this study and they al underwent single-crown restoration. The involved patients were divided into angulated abutment group and straight abutment group. Periodontal probing depth, modified plaque index, modified sulcus bleeding index and peri-implant crestal bone loss in two groups were recorded at 6 months and 2 years after restoration. Cumulative survival rate of the implant denture was calculated by life-table analysis.
RESULTS AND CONCLUSION:There was no significant difference in periodontal probing depth, modified plaque index, and modified sulcus bleeding index between two groups (P>0.05). The annual crestal bone loss showed no significant difference between two groups (P>0.05). Moreover, the 5-year cumulative survival rate with 15° and 20° abutments was 95.6%, and that with straight abutment was 96.4%. The angle of abutments has no correlation with peri-implant soft tissue and peri-implant crestal bone loss, implant restorations with 15° and 20° angulated abutments may be successful y used in the posterior region, whereas the long-term effects need further research.

Objective To investigate the clinical value of joint detection of procalcitoninl (PCT ) ,C-reactive protein (CRP) ,and myocardial enzymes in patients with neonatal hyperbilirubinemia .Methods 30 cases of each cause were included in the study ,which were neonatal hyperbilirubinemia caused by sepsis ,pneumonia ,ABO hemolytic and breast milk jaundice .20 cases of each cause were selected including neonatal hyperbilirubinemia caused by neonatal hepatitis and low birth weight infants .All the cases involved in the study were diagnosed .30 healthy full-term newborns in the same period were recruited as control group .PCT ,CRP and myocar-dial enzymes (AST ,CK ,CK-MB ,and LDH) concentration in serum were determined .Results Compared with the control group , CRP and PCT concentration increased significantly in bacterial infected group (P< 0 .05) .Myocardial enzyme concentration in-creased significantly both in infected group and non-infected group(P<0 .05) .Among myocardial enzymes ,CK-MB concentration increased significantly in bacterial infected group ,low birth weight infants group and ABO hemolytic group(P<0 .01) and increased significantly in breast milk jaundice group and hepatitis group (P<0 .05) .AST and LDH concentration increased very significantly in hepatitis group(P<0 .01) .The specificity of PCT in bacterial infected group was significantly higher than that of CRP (P<0 .05) ,while its sensitivity was significantly lower than that of CRP in pneumonia group (P<0 .01) .Conclusion Changes of PCT , CRP and myocardial enzymes concentration are related to the occurrence and development of neonatal hyperbilirubinemia ,determi-nation of these indicators can be complementary .

Objective To investigate the location of CYLD in the neurons and explore the expression of CYLD in OGD/reperfusion-induced neuronal necroptosis.Methods Primary cortical neurons were cultured for 6days and neuronal purity was observed by double staining immunofluorescence of β3-tubulin and DAPI.The location of CYLD was identified by double staining immunofluorescence of NeuN,DAPI and CYLD using primary cortical neurons cultured for 14 days.Then,primary cortical neurons were divided into 8 groups:Control,EBSS,DMSO,OGD/reperfusion(0 h,2 h,6 h,8 h,12 h).Neurons were pretreated with zVAD-fmk for 30 min,OGD for 2 h and the levels of CYLD were evaluated after reoxygenation at different time points.The peak value(8 h) was chosen as reoxygenation time point.Neurons were divided into two groups as Control and OGD.The levels of CYLD were determined in both cytoplasm and nucleus after OGD 2 h and reoxygenation 8 h.Results The double staining immunofluorescence showed that neuronal cultured purity was about 70％ and the CYLD strongly expressed in nucleus but weakly in cytoplasm.The levels of CYLD increased gradually with different reoxygenation time and arrived at peak value after reoxygenation for 8 h (P ＜ 0.05),which was in accordance with the change of LDH (P ＜0.05) (Control (1.00±0.00),EBSS (1.07 ±0.03),DMSO (1.09 ±0.03),0h (1.40±0.12),2 h (1.74±0.08),6 h (2.25 ± 0.12),8 h (2.97 ± 0.15),12 h (3.01 ± 0.08)).The level of cytoplasm CYLD increased significantly in the OGD group (reoxygenation for 8 h)than that in control group (P＜0.05).But the level of nucleus CYLD had no difference between OGD and control group (P ＞ 0.05),which was in accordance with the results of immunofluorescence.Conclusion The CYLD in neurons cytoplasm is involved in necroptosis induced by OGD/deprivation and downregulating of CYLD has a protective effect on the brain injury resulted from ischemia/ reperfusion.

Objective To evaluate open surgery vs transurethral management for bladder outlet obstruction (BOO) caused by benign prostatic hyperplasia (BPH) of small volume. Methods From May 1993 to June 2002,50 patients were surgically treated.Of them 22 underwent open surgery and 28 underwent TURP plus transurethral incision of bladder neck(TUIBN).There was no statistically significant difference between the 2 groups in age,disease course,preoperative prostate weight and the excised prostate weight.All the surgical procedures were conducted by the same urologist.The efficacy of open surgery and TURP plus TUIBN was comparatively evaluated by IPSS,Qmax and post void residual urine volume(PVR) and hospitalization days. Results The IPSS of those undergoing open surgery decreased from 24.6?3.8 of preoperation to 15.2?3.4 of postoperation ,and the Qmax increased from (8.3?2.9)ml/s to (9.5?3.6)ml/s,and the PVR decreased from(220.0?30.0)ml to(90.0?20.0)ml,and the postoperative hospital stay was 14.2 days.The IPSS of the patients undergoing TURP plus TUIBN decreased from 24.9?4.2 to 5.8?2.7,and the Qmax increased from (8.0?3.1)ml/s to (23.2? 3.8)ml/s,and the PVR decreased from(230.0?28.0)ml to(15.0?4.0)ml,and the postoperative hospital stay was 8.5 days.The postoperative improvement was much greater in the patients undergoing TURP plus TUIBN than those undergoing open surgery as assessed by IPSS,Qmax and PVR (all P

Objective To describe the special ramp lesion, which involves the capsulomeniscal region of posterior horn of medial meniscus and most commonly occurs in association with anterior cruciate ligament(ACL) injury, pre- and intra-operative diagnosis methods, arthroscopy repair technique and follow-up results of arthroscopy second-look & MR review. Methods From April 2002 to April 2005, 89 cases of ACL injury with ramp lesions are enrolled in this series, among them 85 need operation repairing. Arthroscopic ACL reconstruction with hamstring or B-PT-B autograft or allograft and all-inside medial meniscus repair through 2 posteromedial portals and transcondylar portal have been performed. Generally, the ramp lesion accounts for 26.7% of ACL injury, 30.5% for chronic and 19.5% for acute injury respectively. Results Of the repaired ramp lesion cases, 75 cases(88.2%) are available for follow-up, with the duration from 5 to 41 months (mean, 20.2 months). 25 cases underwent arthroscopic second-look and 21 cases received MR evaluation. The study include subjective symptom, clinical examination, and arthroscopic second-look as well as MR review. All of the repaired cases present normal subjective and objective evaluations, and all the 25 second-look cases show completely healing. Of the 21 MR follow-up cases, 18 completely healed, 3 partial healed. Conclusion About 1/3 ACL injuries are associated with medial meniscus ramp lesion, and the morbidity is higher in old injuries than acute injuries. For this combined lesion, one stage ACL reconstruction and meniscus repair was recommended. All-inside meniscus repair is a satisfactory technique for ramp lesion and can get high healing rate.

Objective To evaluate the effects of flapless versus flap implant surgery on the tissues surrounding the implants in the esthetic zone.Methods A controlled study was conducted in 20 patients with a single implant in the anterior esthetic zone,as compared with the flapless and traditional flap implant placement.6 and 12 months after the implant ation,the vertical reduction of labial and lingual bone were assessed by cone beam computed tomography (CBCT);6 and 12 months after the crowns restoration,the peri-implant soft tissues were examined by probing depth (PD),modification sulcus bleeding index (mSBI),papillary index (PPI) and evaluated by pink esthetic score (PES) standard.Results The vertical reduction of the flapless labial and lingual bone was lower than that of the flap,in which the change of labial bone was statistical differences at 6 months after implant surgery between groups (P ＜ 0.05).The differences of PES between two groups were not statistically significant,although PES increased over time in both groups,which the flapless group had a significantly change in PES from crown placement to 12 months (P＜0.05).Conclusions A flapless implant surgery in sufficient bone support may provide a better short-term esthetic result,whereas the longterm effects need further studies.

Objective To detect the changes of number and function of endothelial progenitor cells (EPCs) in gld.apoE-/-C57BL/6 mice,and to investigate whether premature atherosclerosis of gld.apoE-/-C57BL/6 mice was mediated by the dysfunction of these EPCs.Methods EPCs were isolated from peripheral blood and bone marrow of four types of C57BL/6 female mice:gld+/+apoE+/+,gld,apoE-/-and gld.apoE-/-.The percentage of EPCs was analyzed by FACS as CD11b-Sca-1+CD309+ cells.The attached cells were stained with DiI labeled acetylated low-density lipoprotein (DiI-ac-LDL) and FITC-labeled Ulex Europaeus agglutinin 1 (FITC-UEA-1) double staining to determine their phagocytic function.The adherent function of EPCs was determined by calculating the number of re-cultured EPCs.The capacity of EPCs to form the cavity structure was detected by calculating the number of the formed vascular-like structure.Results The percentage of circulating EPCs was significantly decreased in the gld.apoE-/-group (0.012±0.002)％ compared to the gld+/+ apoE+/+ group [(0.039±0.005)％,P＜0.01],the gld group [(0.025±0.001)％,P＜0.05],and the apoE-/-group [(0.028±0.002)％,P＜0.01].The percentage of bone marrow derived EPCs was decreased in the gld.apoE-/-group (0.12±0.01)％ compared to the gld+/+apoE+/+ group [(0.42±0.05)％,P＜0.05].The percentage of DiI-acLDL and FITC-UEA-1 double positive cells was decreased in the gld.apoE-/-group [(59.2±2.1)％] compared to the gld+/+apoE+/+ group [(87.5±3.0)％,P＜0.01],and the gld group [(84.2±6.0)％,P＜0.01] ; the adherent function of EPCs was impaired in the gld.apoE-/-group [(50.0±5.3)％] compared to the gld+/+ apoE+/+ group [(86.0±7.3)％,P＜0.01],the gld group [(73.0±1.0)％,P＜0.01],and the apoE-/-group [(65.0±4.0)％,P＜0.05] respectively.The capacity of EPCs to form the cavity structure was decreased in the gld.apoE-/-group (4.0±0.3) compared to the gld+/+apoE+/+ group (12.0±1.4,P＜0.01).Conclusion The number of EPCs is decreased in the gld apoE-/-C57BL/6 mice,the adhesion,phagocytosis and angiogenic function of EPCs in the bone marrow are impaired,which may be one of the causes of lupus with atherosclerosis.

Objective To evaluate the MRI findings of the cruciate ligaments cysts in correlation with clinical feature.Methods Seven patients with cruciate ligaments cysts were reviewed. There were 5 men and 2 women, aged from 22 to 38 years (mean 30.6 years). All patients were examined by the knee MRI. The clinical manifestations such as symptoms, duration of symptoms, sign, and the history of trauma were evaluated and then correlated with the MRI findings.Results Five ganglion cysts were found in the anterior cruciate ligaments and 2 in the posterior cruciate ligaments. All cysts were either oval or lobulated in shape. Most of them were located along the posterior surface of the ligaments. All cysts were resected or aspirated through arthroscopy. After surgery, all patients were asymptomatic without recurrence during follow-up.Conclusion Intraarticular cysts of the cruciate ligaments are uncommon. It can cause knee pain, limitation of knee extension and flexion. The unique MR images of the cysts help to diagnose patients with chronic knee pain, as well as to plan the treatment. The results of arthroscopic treatment for the cysts were satisfied.
