Objective:To evaluate the treatment effects of the half-columnar shaped mandibular block bone onlay grafting technique for augmentation of the resorbed maxillary anterior alveolar ridge after single tooth missing.Methods: A total of 15 sites of 14 patients received ridge augmentation surgeries.The recipient sites were prepared with trephines,the half-columnar shaped bone blocks were harvested from the ramus and external oblique ridges with trephines according to diameters of the recipient sites.The bone blocks were placed as lateral onlay grafts on recipient beds and secured by means of titanium screws.Particulate bone was added and absorbable membranes were used to stabilize and protect the grafts.After a mean interval of 4.5 months of healing the flaps were re-opened,the screws were removed and non-submerged implants were placed.The width and height of the alveolar ridges were recorded.After 3 months,implant-supported crowns were provided to the patients.One year later,the peri-impant condition and the marginal bone resorption on the proximal sites were observed.Results: Mean lateral augmentation obtained at the time of bone grafting was(3.8?0.8) mm(x?s),5 out of 15 sites exhibited a mean of 3 mm of vertical augmentation.The mean healing time was 4.5 months,the mean percentage of horizontal and vertical bone resorption in the mean time were 8% and 7% respectively.No major complications were recorded at donor sites.No implant was lost during the study period.Clinical parameters and probing depth(≤4 mm) demonstrated the presence of a healthy peri-implant mucosa after 1 year of prosthetic reconstruction.The clinical and radiographic bone observations showed no more than 1.2 mm of resorption after bone graft and implant placement.Conclusion: The half-columnar shaped mandibular bone graft(from the ramus and external oblique ridge) is a promising technique for bone augmentation in localized alveolar ridge defects after single tooth missing.This procedure offers easy access,good bone quantity for localized repair,low morbidity,decreased complaints of postoperative sensory disturbances or discomfort,minimal graft resorption,and a shorter healing time as compared with other methods for bone repair.

BACKGROUND:Whether long time exposure to the lead concentration which is withinthe state allowed range will cause any bad effects on people's health?OBJECTIVE: To investigate the nerve conducting velocity (NCV) and other biological indices of workers who are exposed to low concentration lead.DESIGN: It was an investigation and the subjects were workers exposed to low concentration lead.SETTING: Occupational Disease Department and Electrophysiological Department of Xinhua Affiliated Hospital of the Shanghai Second Medical University.PARTICIPANTS: In lead contact group were 66 heat treatment workers who were exposed to lead and received physical examination from September 2000 to October 2002. In control group were 40 office workers that worked at the same factory but were not exposed to lead.METHODS: Questionnaire and laboratory examination were adopted for measurement of NCV and other biological indices like blood lead, blood zinc protoaetioporphyrin (ZPP), blood free protoporphyrin (FPP) and hemoglobin content in the two groups. And the relative risk analysis was conducted.biological indices in both groups.RESULTS: All the 106 subjects entered analysis stage. In lead contact group there were 34 workers of more than 10 working years and the other ulnar nerve in those of over 10 working years were faster than those in control group [(50.11 ±4.76) m/s, (63.11±2.58) m/s vs (47.59±4.86)m/s,those of over 10 working years was higher than those of less than 10years [(0.568±0.28), (0.425±0.31) μmol/ L, P ＜ 0.05]. So was the FPP level [(2.24±0.32), (2.09±0.27) μmol/L, P ＜ 0.05] and urine lead level [(0.087±0.008), (0.083±0.007) μmg/L, P ＜ 0.05]. The ZPP level of those of over 10 working years was also higher than those less than 10 years [(1.42±0.33) μmol/L vs (1.25±0.35) μmol/L, P ＜ 0.05] and control [(1.42±0.33) μmol/L vs (1.22±0.44) μmol/L, P＜ 0.05]. The hemoglobin of those of over 10 working years was lower than those of less than 10 years [(12.26±4.5) g/L vs (14.55±4.81) μmol/L, P ＜ 0.05] and control [(12.26±4.5) g/L years presented abnormality in conducting sensory signals and the abnormality rate was 3% (1/32). Whereas four cases in those with more than 10working years did so and the abnormality rate was 12% (4/34). As for biological indices, one case in those less than 10 working years was beyond normal values (abnormality rate 3%) and five did so in those of over 10working years (abnormality rate 15%). It could be seen that changes in both NCV and biological indices of those of over 10 working years were more serious than those les than 10 years exposure with the relative risks of 4.1 and 5.3 respectively.CONCLUSION: Persistent exposure to lead not only alters biological indices but also damages nervous system in different degrees. Sensory verve of lower extremities and motor nerves of upper extremities are usually damaged first. Peripheral nerve injury is common in workers of over 10 working years. Because the regeneration of nervous system is poor, so the nerve injury is usually irreversible. Therefore the neuroelectrophysiological changes always predict early nerve injury and so neuroelectrophysiological monitoring can be adopted for prevention of nerve injury.

Objective:To develop an indirect enzyme-linked immunosorbent assay (ELISA) for semi-quantification of major allergen parvalbumin in fish.Methods:The soluble proteins were prepared from both white and dark muscles of seven species of freshwater fish and five species of marine fish.Tricine-SDS-PAGE and Western blot were performed to examine the protein patterns of fish muscle extracts.Natural parvalbumin being used to make calibration curve was purified from silver carp (Hypophthalmichthy molitrix) by ammonium sulphate fractionation,followed by ion exchange and gel filtration chromatography.The molecular mass of purified protein was estimated by Tricine-SDS-PAGE and identified by Western blot with anti-frog parvalbumin monoclonal antibody PARV-19.ELISA using PARV-19 was carried out to evaluate parvalbumin contents in white and dark muscles.Results:Tricine-SDS-PAGE revealed species-specific differences in proteins of heated extracts.Western blot confirmed that the major bands were showed in Tricine-SDS-PAGE with the molecular masses of 10-14 kD corresponded to parvalbumins recognized by PARV-19 and various numbers of isoforms of parvalbumin existed in different species of fish.There might be some differences in the parvalbumin contents and the epitope region was recognized by PARV-19 based on the differences in relative intensities of protein immunodetection.The ELISA showed that the contents of parvalbumin were 4 to 33 folds higher in the white muscle than in the dark muscle and varied greatly in different species of fish.Conclusion:These results validate that the dark muscle might be less allergenic than the white muscle due to the lower content of parvalbumins,and it is suggested that the commercial anti-parvalbumin antibody PARV-19 can be used to detect parvalbumins from the commercially important species of fish tested in this study and the method we develope succeeds to detect the major allergen in various species of fish.

Objective To investigate the stroke occurrence of chronic kidney disease (CKD) and its related factors, especially the carotid atherosclerosis. Methods The data of stroke occurrence in 700 CKD patients hospitalized in Renji Hospital during 2007 were analyzed retrospectively. The incidences of stroke were compared among CKD [Ⅰ-Ⅱ, CKD Ⅲ-Ⅴ non-dialysis patients and dialysis patients. Carotid atherosclerosis of 409 CKD patients was examined by color Doppler ultrasound. The related factors were selected by Spearmnan correlation analysis and Logistic regression analysis. Results Of 700 CKD patients, 67 cases (9.57%) experienced at least one episode of stroke, which was much higher than that of general population. The related factors of stroke in CKD included GFR, age, SBP, CRP, Lpa, serum glucose, pre-albumin, HDL and carotid atherosclerosis. Logistic regression revealed that SBP (β=1.021, P=0.042), CRP (β=1.008, P=0.024) and carotid atherosclerosis (β =3.456, P=0.025) were risk factors of stroke in CKD. Incidence of carotid atherosclerosis was high (50.37%) in CKD patients, besides it was significantly higher in CKD patients with stroke history as compared to those without stroke history (80.0% vs 47.4%, P<0.01). Conclusions The incidence of stroke is quite high in CKD patients, which is closely associated with hypertension, inflammation and glyeolipid metabolism disorder. Carotid atherosclerosis is common in CKD patients with stroke, which may be helpful in screening cerebrovascular diseases in CKD patients.

Objective To systematically evaluate the role of laparoscopic living donor hepatectomy in living donor liver transplantation (LDLT).Methods A systematic literature search was conducted on Medline-Pubmed,Embase,Cochrane Library to find studies on laparoscopic living donor hepatectomy for LDLT.All extracted data were analyzed using the RevMan 5 software.Results Ten studies with a total of 1 059 participants were included in this analysis.Laparoscopic donor hepatecomy (LDH) was associated with significantly less intraoperative blood loss [SMD =-0.39,95％ CI (-0.73,-0.05),P ＜ 0.05],lower peak level of postoperative total bilirubin [SMD =-0.24,95％ CI (-0.47,-0.01),P ＜ 0.05]and longer operative time [SMD =0.50,95％ CI (0.04,0.96),P ＜0.05] when compared with those operated with open surgery.On subgroup analyses,hospitalization stay decreased in patients who underwent LDLT with grafts obtained by complete living donor hepatectomy (LDH) and left lateral sectionectomy (both P ＜ 0.05).LDH was comparable to open surgery in donor complication rates and in-hospital cost (P ＞ 0.05).There were no differences on the harvested liver graft size,ischemic time,recipient postoperative liver function and complications between the two groups (P ＞ 0.05).Conclusions Laparoscopic hepatectomy in living donor is a safe procedure for graft-harvesting,which improved the clinical outcomes of the donor,liver graft and recipient in LDLT.It has also the advantages of reduced blood loss,low peak levels of postoperative total bilirubin and short hospitalization stay.

Objective:To detect the value of utilizing bpMRI in prostate biopsy in the detection of prostate cancer with PSA≤20ng/ml.Methods:The clinical data of 394 patients who underwent prostate biopsy in the First Affiliated Hospital of Nanjing Medical University from November 2017 to October 2019 were retrospectively analyzed. Of all the patients, 177 underwent modified systematic biopsy, named TRUS group, 217 patients accepted pre-biopsy bpMRI examination, undergoing modified systematic biopsy if Prostate Imaging Reporting and Data System (PI-RADS) score < 3 or MRI-TRUS cognitive fusion targeted prostate + systematic biopsy if PI-RADS score ≥ 3, named MRI group. The median age of TRUS group was 66 (61, 74) years old, prostate specific antigen (PSA) was 9.52 (7.26, 12.30) ng / ml, and prostate volume (PV) was 36.84 (28.95, 57.72)ml. The median age of MRI group was 66 (59, 72) years old, PSA was 8.84 (6.65, 12.16) ng/ml, and PV was 39.45 (29.25, 58.69)ml. There was no difference in above parameters between the two groups. The χ 2 test was used to compare the detection rate of prostate cancer and clinically significant prostate cancer (CsPCa) between the two groups. Results:There was no significant difference in the detection rates of prostate cancer between TRUS group and MRI group [51.41% (91/177) vs. 48.39% (105/ 217), P = 0.550], but the detection rates of CsPCa were significantly different [26.55% (47/177) vs. 36.41% (79/217), P = 0.037]. In patients with PSA ≤ 10 ng / ml, there was no significant difference in the detection rates of prostate cancer between the two groups [43.62% (41/94) vs. 43.08% (56/130), P = 0.936], but there was a significant difference in the detection rates of CsPCa [17.02% (16/94) vs. 28.46% (37/130), P = 0.047]. There was no significant difference in the detection rates of prostate cancer [60.24% (50/83) and 56.17% (48/87), P= 0.504] and the detection rates of CsPCa [37.35% (31/83) vs. 48.28% (42/87), P = 0.150] between the two groups. The total detection rates of the last two needles in TRUS group and MRI group were 23.16% (41/177) and 36.63% (86/217), respectively, with significant difference ( P=0.001); the detection rates of CsPCa in the last two needles were 11.86% (26/177) and 29.03% (63/ 217), respectively, with significant difference ( P < 0.001). In MRI group, the detection rates of prostate cancer in patients with PI-RADS score <3, 3, 4, 5 were 21.21% (7/33), 25.84% (23/89), 73.24% (52/71), 95.83% (23/24), respectively; the detection rates of CsPCa were 12.12% (4/33), 17.98% (16/89), 54.93% (39/71), 83.33% (23/24), respectively. Conclusions:In patients with PSA ≤ 20 ng / ml, prostate biopsy based on bpMRI may improve the detection of CsPCa, especially in patients with PSA ≤ 10 ng/ml.

Objective: To explore the application value of endoscope in probing the chronic wound with sinus tract in clinic. Methods: Twenty-eight chronic wounds with sinus tracts from 27 patients conforming to the inclusion criteria admitted to Outpatient Department of Wound Healing Center of Ruijin Hospital from December 2017 to March 2018 were investigated in a prospective and self-controlled trial. After being cleaned, the diameter of the opening of sinus tract was measured with a rule. A probe was used to measure the depth of a sinus tract according to the touch from the probe extremity in operation, and to measure the depth of a sinus tract that could be observed with naked eyes with the help of a pair of hemostatic forceps. Five minutes later, a probe was inserted deeply into the sinus tract to measure the depth under the endoscopic view combined with touch from the probe extremity in operation. Afterwards, the sinus tract was observed with endoscope, and the depth of the tract which could be observed under the endoscopic view was measured using a probe inserted deeply into the sinus tract. After completion of the above exploration, the sinus tract was infused with contrast agent Omnipaque 350 and scanned by computed tomography (CT) later to obtain its depth. The following indicators were calculated: the ratio of the depth of the sinus tract measured by CT to the diameter of the opening of the sinus tract (hereinafter referred to as the depth/diameter ratio of the sinus tract), the deviation rate comparing the depth of the sinus tract measured by conventional method (measured by probe only) and by endoscope (measured by probe under the endoscope view) with the depth of the sinus tract measured by CT (hereinafter referred to as the deviation rate of the measured depth of the sinus tract), the deviation rate comparing the depth of the sinus tract that could be observed measured by conventional method and by endoscope with the depth of the sinus tract measured by CT (hereinafter referred to as the deviation rate of the depth of the sinus tract that could be observed). Data were processed with paired t test. Pearson correlation analysis was applied to analyze the correlation between the depth/diameter ratio of the sinus tract and the deviation rate of the measured depth of the sinus tract and the deviation rate of the depth of the sinus tract that could be observed by conventional method and by endoscope. Results: The depth/diameter ratio of the sinus tract of this group of wounds was 1-32 (8±7). The deviation rate of the measured depth of the sinus tract and the deviation rate of the depth of the sinus tract that could be observed by conventional method were (19±14)% and (79±18)%, respectively, both obviously larger than (9±9)% and (25±25)% by endoscope (t=3.837, 13.626, P<0.01). Positive correlation existed between the depth/diameter ratio of the sinus tract and the deviation rate of the measured depth of the sinus tract by conventional method, and between the depth/diameter ratio of the sinus tract and the deviation rate of the depth of the sinus tract that could be observed by conventional method and by endoscope (r=0.514, 0.585, 0.651, P<0.01). However, there was no obvious correlation between the depth/diameter ratio of the sinus tract and the deviation rate of the measured depth of the sinus tract by endoscope (r=0.113, P>0.05). Conclusions Compared with the conventional method, application of endoscope is able to get more accurate data of chronic wounds with sinus tracts and observe the wounds with wider range.

Objective:To compare the differences of prostate cancer (PCa) and clinically significant prostate cancer (CsPCa) positive rate and postoperative complications between transperineal cognitive prostate biopsy (COG-TPBx) and transrectal cognitive prostate biopsy (COG-TRBx) based on biparametric magnetic resonance imaging (bpMRI).Methods:The data of 276 patients undergoing prostate biopsy from January 2019 to June 2021 in the First Affiliated Hospital of Nanjing Medical University were retrospectively reviewed. 157 patients underwent COG-TPBx(TPBx group) and 119 patients underwent COG-TRBx (TRBx group). The average age [(66.39 ± 8.31) vs. (66.30 ± 8.42)years], body mass index (BMI) [(23.85±2.49) vs. (23.68±2.61) kg/m 2], PSA values [9.43(1.47-19.80) vs. 8.94(0.66-19.99) ng/ml], prostate volume [37.92(13.99-167.40) vs. 40.78(11.67-188.21) cm 3], PSA density [0.21(0.04-1.17) vs. 0.20(0.04-1.04) ng/(ml·cm 3)], and suspicious digital rectal examination [17.20% (27/157) vs. 21.10% (25/119) ] were not significantly different between TPBx group and TRBx group. The positive rate of PCa, CsPCa, as well as post-biopsy complications of the two groups were compared. Results:There were no significant differences in the positive rate of PCa [49.68%(78/157) vs. 47.06%(56/119), P=0.666] and CsPCa [38.22%(60/157) vs. 34.45%(41/119), P=0.520] between the two groups. In stratification analysis, TPBx group has a significantly higher positive rate of both PCa [54.69%(35/64)] and CsPCa[43.75%(28/64)] in apex zone than TRBx group[39.62%(21/53) and 20.75%(11/53), all P<0.05). Moreover, the postoperative complications were not significantly different in TPBx group compared to that in TRBx group [10.19% (16/157) vs. 12.61%(15/119), P= 0.567]. Conclusions:Our investigations revealed that the overall positive rate of PCa, CsPCa, and the complications were not statistically different between COG-TPBx and COG-TRBx. COG-TPBx has a significantly higher positive rate of both PCa and CsPCa in apex zone.

Objective:To investigate the clinical feasibility of three-dimensional contrast-enhanced ultrasound (3D-CEUS) in the quantitative assessment of blood perfusion of hepatocellular carcinoma (HCC).Methods:Between January 2020 and August 2021, 36 HCC patients (39 lesions in total) confirmed by pathology and clinical diagnosis without any treatment from Zhongshan Hospital, Fudan University were enrolled and underwent both 2D-CEUS and 3D-CEUS examinations. Each examination last for 150 s and all images were recorded, and then the data were analyzed. A region of interest was manually drawn along the margin of the whole tumor and then the time-intensity curve (TIC) generated. The following perfusion parameters were extracted: peak intensity (PI), peak time (TTP), ascending slope (AS), mean transit time (MTT) and area under the curve (AUC). After calculating the quality of fit (QOF) of the curve, the intraobserver agreement of the 3D-CEUS quantitative parameters obtained by the same doctor between two times were assessed, and the consistency of the 3D-CEUS and 2D-CEUS quantitative parameters was evaluated when QOF>75%. The differences of the quantitative parameters between different groups (divided by depth of 8 cm and necrosis rate of 50%, respectively) in 3D-CEUS were compared.Results:There were 38 lesions (97.4%, 38/39) with QOF>75% in 3D-CEUS. The intraobserver agreement was excellent, the intraclass correlation efficient(ICC) values was 0.85-0.99. The consistency of the time quantitative parameters (TTP and MTT) were high (the ICC values of 0.87 and 0.91), and the correlation of intensity quantitative parameters were substantial, the rs values were 0.71, 0.72 and 0.71. The differences in 3D-CEUS quantitative parameters of the two groups of lesions with different depths were statistically significant (all P<0.05); but there were no significant differences in quantitative parameters between the two groups with different necrosis rate (all P>0.05). Conclusions:Quantitative 3D-CEUS is an useful and creditable tool in evaluating the blood perfusion of HCC, especially when the depth of lesion was less than 8 cm.
