Objective To systematically review the efficacy and safety of mini-percutaneous nephrolithotomy (MPCNL) and flexible ureteroscopic lithotripsy (FURL) in management of lower pole kidney stones.Methods PubMed, Embase, Scopus, Cochrane library, CNKI, VIP and Wanfang Data were searched from the beginning of database to September 2016 and clinical trials that compared the two above operation for treatment of lower pole stones were collected.Two researchers independently filtered literature,extracted data and evaluated the methodological quality of research papers.The meta-analysis was performed using the RevMan 5.3 software.Results One randomized and seven non-randomized studies were analyzed, which consists of 621 patients including MPCNL group 327 cases, FURL group 294 cases.The results of meta-analysis showed that MPCNL was better than FURL in stones clearance (OR =2.65,95％ CI 1.58-4.46,P ＜ 0.01) and operative time (WMD =-21.86,95％ CI-28.52--15.20, P ＜ 0.01).FURL was better in hospital stay time (WMD =2.28,95％ CI 0.29-4.28, P =0.02), decrease in haemoglobin levels (WMD =0.78,95 ％ CI 0.68-0.89, P ＜ 0.01), bleeding (OR =5.11,95 ％ CI 1.12-23.31,P =0.04), transfusion(OR =7.04,95％ CI 1.59-31.15, P =0.01).There was no significant difference in fever,urinary tract infection, hematuria (P ＞ 0.05).Conclusions Both MPCN and FURL are safe and effective for the treatment of lower pole stones, MPCNL can get higher stone clearance rates and shorter operation time.However, FURL can get shorter hospitalization time and lower complication rates.

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.

ObjectiveTo verify the reliability of the mouse model of cerebral cortical microinfarct induced by two-photon microscopy and to explore its pathological changes.MethodsSeventeen male C57BL/6J mice were randomly divided into a microinfarct group (n=11) or a sham operation group (n=6).A thinned cranial window of 3 mm diameter was performed over the cerebral cortex with a high-speed micro-drill until the small blood vessels were clearly observed under a dissecting microscope.Then, a permanent single cortical penetrating arteriole occlusion was induced with a gradually enhanced ultrashort laser irradiation through the thinned cranial window with two-photon microscopy.At 7 days after modeling, the cerebral microinfarct volume was measured with HE staining, and the neuron loss, activation of glial cells and deposition of 3-nitrotyrosine were assessed using immunohistochemistry.ResultsThe target vessels of cerebral cortex in 8 (72.7%) mice were occluded and the microinfarcts formed in the microinfarct group, and the average microinfarct volume was 317.23±20.29 μm3.There were remarkable neuron loss and microglia infiltration in the infarcted core, a large number of reactive astrocytes surrounding the infarcted lesion, and massive deposition of 3-nitrotyrosine in the peri-infarct area.No infarcts were observed in the sham operation group.The deposition of 3-nitrotyrosine in the sham operation group was significantly less than that in the microinfarct group (8.00±1.48 vs.98.38±9.10;t=23.962, P<0.001).Conclusions The mouse model of cerebral cortical microinfarct induced by two-photon microscopy is reliable, and its histopathologic changes are consistent with the pathologic features of cerebral microinfarct.

Objective To investigate the protective effect of ADP-ribosylation factor 6 inhibitor on acute kidney injury induced by sepsis in mice.Methods In February 2018,thirty male BALB/c mice were divided into uninfected group (5 mice),fluconazole group (5 mice),ADP-ribosylation factor 6 inhibitor group (10 mice)(inhibitor group) and saline control group (10 mice)(control group) by random number table method.In fluconazole group,inhibitor group and control group,1 × 105 CFU of Candida albicans was injected via tail vein for modeling.The uninfected group was injected with equal volume of saline.After 3 hours,inhibitor group was injected with 1.032 mg ADP-ribosylation factor 6 inhibitor,and fluconazole group was injected with 51 μg fluconazole.The control group were injected with equal volume of saline as inhibitor group.After 24hours,serum creatinine,urea nitrogen were measured by kit method.The mice were clinically scored for sepsis severity according to signs and symptoms after treatment and histopathological changing of kidney tissue were observed and scored according to the damage area of renal cortical with hematoxylin-eosin staining.Results The clinical scores,serum creatinine,urea nitrogen and pathological scores of uninfected group were 0,(0.98 ± 0.38) μmol/L,(9.77 ± 0.36) mmol/L,(0.88 ± 0.30),respectively.The fluconazole group were (0.80 ± 0.84),(1.09 ± 0.51) μmol/L,(9.64 ± 0.17) mmol/L,(1.22 ± 0.270),respectively.The inhibitor group were (2.80 ± 1.32),(1.43 ± 0.50) μmol/L,(12.05 ± 1.20) mmol/L,(2.04 ± 0.55),respectively).The control group were (5.20 ± 1.87),(2.96 ± 1.55) μmol/L,(13.94 ± 1.94) mmoL/L,(2.67±0.55).The difference was statistically significant between inhibitor group and the control group both (P ＜ 0.05).Conclusions ADP-ribosylation factor 6 inhibitor reduce acute kidney injury induced by sepsis in mice.

Objective:To explore the efficacy and safety of pretreating with oral immunosuppressants alone for ABO-incompatible (ABOi) renal transplant recipients with an initial isoagglutinin titer <1: 8.Methods:From September 2014 to October 2019, 16 cases of ABOi renal transplantation pretreated with oral immunosuppressants alone and 32 cases of ABO-compatible (ABOc) renal transplantation were recruited for comparing the inter-group incidence of graft function, acute rejection, infection and recipient and allograft survival.Results:The 16 ABOi renal transplantations were AB-to-A(n=4), AB-to-B(n=3), A-to-B(n=1), B-to-A(n=4), A-to-O(n=2) and B-to-O(n=2). The initial isoagglutinin titer (IgM & IgG) and that on the date of transplantation were both ≤1∶8. The median follow-up period was 495(90-1696) days. One patient in ABOi group underwent allograft nephrectomy due to hyperacute rejection. The graft survival rates were 93.75%(15/16) and 100%(32/32) in ABOi and ABOc groups respectively. No recipient died. No significant inter-group difference existed in postoperative renal function after 6 months (serum creatinine μmol/L: 114.30±28.13 vs. 106.08±23.80, P=0.38; eGFR ml/min/1.73 m 2: 64.93±19.60 vs. 82.34±22.58, P=0.13). In ABOi group, there were 3 episodes of postoperative infection, 2 episodes of acute rejection within 2 weeks (including 1 episode of hyperacute rejection) and 1 episode of acute rejection after 2 weeks; 5 episodes of postoperative infection, no acute rejection within 2 weeks and 5 episodes of acute rejection after 2 weeks in ABOc group. No significant inter-group difference existed in the incidence of infection or rejection ( P>0.05). Conclusions:Using oral immunosuppressant alone is both safe and feasible for ABOi renal transplantation recipients with an initial isoagglutinin titer ≤1∶8. It may greatly simplify the pretreatment scheme for those with a low initial isoagglutinin titer and lower the incidence of complications.
