Aim To explore the protective effect of lo-ganin ( an active component in Cornus officinalis ) on podocyte injury induced by advanced glycation end products ( AGEs) and its possible mechanism. Meth-ods Mouse podocytes were cultured in vitro and di-vided into Normal group, model group ( AGEs group) , loganin group and aminoguanidine group ( set as posi-tive control) . After being incubated with loganin( final concentrations are 0. 1, 1, 10 μmol · L-1 ) for 1 h, podocytes were stimulated by AGEs of 100 mg · L-1 for 24 h. Then, the cell viability was measured by u-sing MTT method. Podocytes apoptosis was evaluated by Hoechst33342/PI staining and flow cytometry. Re-ceptors of advanced glycation end products ( RAGE ) ,desmin and apoptosis-related protein like Bax, Bcl-2, cleaved caspase-3 in podocytes were detected by Western blot. Results Loganin ameliorated podocyte injury induced by AGEs, down-regulated the expression of desmin and RAGE. Loganin also reduced the apoptotic rate of podocytes and decreased the ratio of Bax/ Bcl-2 and the expression of pro-apoptotic protein cleaved caspase-3 in podocytes. Conclusion Loganin could ameliorate podocyte injury, and its mechanism may be related to the decrease of the expression of RAGE and inhibition of the apoptotic pathway.

ObjectiveTo introduce the indications and operative procedure of anatomic reconstruction of the distal radioulnar ligaments in patients with chronic instability of the distal radioulnar joint(DRUJ),and report its preliminary clinical results.Methods From October 2008 to June 2009,6 patients with instability of the DRUJ underwent anatomical reconstruction using a free palmaris longus tendon graft,including 4 males and 2 females with an average age of 22 years.A 5 cm dorsal incision was made between the fifth and sixth extensor compartments.An L-shaped flap was created in the DRUJ capsule.This flap is then elevated proximally to expose the articular surface of the DRUJ and the proximal triangular fibular cartilage complex(TFCC).A tunnel was made through the radius.The other tunnel was made between the ulnar neck and the fovea of the ulnar head.A whole-length palmaris longus tendon graft was taken.The volar opening of the radius tunnel was exposed through a longitudinal incision radial to the flexor carpi ulnaris tendon.One end of the graft was pulled to the palmar side easily through the tunnel.A hemostat was penetrated through the volar capsule to the volar side proximal to the remaining TFCC.The end of the graft was grasped with the hemostat and pulled back along this tract.Both graft limbs were passed through the ulnar tunnel to exit at the ulnar neck.One limb of the tendon was passed around the ulnar neck and deep to the ECU sheath.With the forearm in neutral rotation,the limbs were pulled taut,tied together,and secured with sutures.Immobilize the extremity in a long-arm plaster splint with the forearm in neutral position for 4 weeks,and changed to a short arm cast for an additional four weeks.ResultsThe average follow-up period for all 6 patients was 14 months(range,9-24).No infection and sensory nerve branch disturbance occurred.The pain symptom was reduced and the grip force was improved significantly.A functional evaluation was performed using the modified Mayo wrist scoring system.All patients had better wrist scores postoperatively in the short (mean,95) term compared to preoperatively(mean,69).Five patients satisfied with the final result.Conclusion Anatomic reconstruction of the distal radioulnar ligaments is indicated for chronic DRUJ instability without osteoarthritis,it is a reliable method with a very good short term follow up result.Restoration of the radioulnar ligaments offers the best possibility to restore the normal DRUJ primary constraints and kinematics.

Aim To observe the protective mechanism of loganinand morroniside ( active components in Cornus officinalis) on HUVEC injury induced by advanced glycation end products ( AGEs ) .Methods HUVECs were cultured in vitro and divided into control group , model group ( AGEs group ) , loganin group , morroni-side group and aminoguanidine group ( set as positive control).After being incubated with loganin and mor-roniside( final concentrations were 100,10,1 μmol?L-1 ) for 1 h, HUVECs were stimulated by AGEs of 200 mg? L-1 for 24 h.Then, the cell viability was measured by using MTT method .The supernatant was extracted and the levels of NO ,ET-1,MCP-1,VCAM-1 were measured by the corresponding kits .Receptors of advanced glycation end products ( RAGE ) and NF-κB in HUVEC were detected by Western blot .Results Loganin and morroniside could inhibit HUVEC injury induced by AGEs .In model group ,the contents of ET-1,MCP-1,VCAM-1 increased(P<0.01),the content of NO decreased ( P <0.01 ) and the expression of RAGE and NF-κB increased(P<0.01); however,lo-ganin and morronside could reduce the ET-1,MCP-1, VCAM-1contents,increase the NO content and down-regulate the expression of RAGE and NF-κB to differ-ent extents .Conclusion Loganin and morroniside could ameliorate HUVEC injury , and its mechanism may be related to inhibit inflammation , the improve-ment of endothelial cell function , and the decrease of the expression of RAGE .

Objective To explore the features of peripheral blood immune cells in long-term survival recipients after liver transplantation.Methods The expression of T subsets (Th1,Th2,Th17,Th22,Tregs),NK cells,NKt cells,Bregs,MDSC in long-term survival recipients (postoperative follow-up time ≥5 years,30 cases),short-term survival recipients(postoperative follow-up time ≤1 year,15 cases) and healthy control (15 cases) were determined by flowcytometry.Results Th17 cells were significantly higher in the long-term group compared with short-term group and healthy control group(P ＜0.01).Tregs in long-term group compared with short-term group were significantly higher (P ＜ 0.01),but the difference was not statistically significant compared with healthy control group (P ＞ 0.05).NK cells were significantly higher in long-term group compared with short-term group and healthy control group (P ＜ 0.01).MDSC were significantly higher in long-term group compared with short-term group and healthy control group (P ＜0.01).Conclusions Th17,Tregs,NK cells and MDSC were significantly higher in long-term survival of liver recipients,which may be related to immune tolerance.

Objective:To evaluate the short-term outcomes of modified reverse Sauvé-Kapandji technique in treating the congenital radioulnar synostosis.Methods:A retrospective analysis was performed on the data of 46 congenital radioulnar synostosis patients were treated with modified reverse Sauvé-Kapandji technique in Beijing Jishuitan Hospital from December 2018 to January 2020, including 38 males (45 sides), 8 females (9 sides), average age 6.6 (3.2, 8.1) years old. All the patients were classified as type III according to Cleary-Omer classification and were followed up for at least 1 year. All the patients were treated with same operation, in which 1.5 cm shaft was resected at the proximal radius, allogeneic graft tendon was used as interposition, and rotational osteotomy was performed in the middle of the ulnar shaft, with intramedullary needle or Kirschner wire fixation, depending on the intramedullary width of ulnar shaft. The radiological features were collected and recorded preoperatively and at the latest follow-up, together with the following evaluation indexes: modified Morrey tasks score, subjective function score, active forearm rotation range without compensation, active forearm rotation range with wrist joint compensation, and active forearm rotation range with wrist and shoulder joint compensation.Results:All patients were followed up for 14.6±3.4 months (range, 11.2-19.5 months). The uncompensated forearm rotation Angle was 0.0°±0.0° before surgery and 62.3°±23.7° after surgery. The forearm rotation angles before and after surgery with wrist compensatory surgery were 86.9°±29.4° and 133.2°±27.9°, respectively. The forearm rotation angles before and after surgery with wrist and shoulder joint compensatory surgery were 205.2°±42.7° and 245.2°±35.8°, respectively. There were statistically significant differences in the above indexes before and after surgery ( t=8.71, P<0.001; t=2.54, P=0.030; t=5.05, P<0.001). Ulnar union was observed in 31 patients (37 sides) after the operation, and the union duration was 6.1±2.3 months. There were 15 patients (17 sides) ulnar shafts faced with postoperative delayed union, the union duration was 8.4±1.6 months and were recovered after prolonging brace fixation and orthopedic shock wave treatment. The scores of subjective function and improved Morrey tasks of the 43 sides with good pseudo-joint were 12.1 (0.0, 20.8) and 0.7 (0.0, 1.0) points, respectively, which were improved compared with 33.9 (25.0, 41.6) and 3.2 (2.0, 4.0) points before surgery. The differences were statistically significant ( Z=-2.44, P=0.015; Z=-2.83, P=0.005). There were 11 forearms with postoperative pseudo-joint re-ankylosis, the average forearm rotation ranges without compensation was 11.4°±10.5°(range, 0°-30°), the average forearm rotation ranges with wrist compensation was 98.6°±15.9° (range, 80°-120°), the average forearm rotation ranges with wrist and shoulder compensation was 231.7°±16.9° (range, 210°-255°). The average subjective function scores was 26.7 (8.3, 39.6). The average modified Morrey tasks scores was 1.2 (0, 2), and there were no other postoperative complications. Conclusion:The reverse Sauvé-Kapandji technique showed a satisfying short-term outcome, and can be a new choice of treatment for type III congenital radioulnar synostosis.

To introduce the surgical procedure of orthopaedic robot-assisted vascularised fibular grafting for the treatment of ANFH and report the short-term result. Methods From September, 2016 to November, 2018, 17 patients (21 hips) with ANFH had undergone robot-assisted free fibular grafting. There were 14 males and 3 females, of which, 8 cases were associated with the right side, 5 cases the left side, and 4 cases with both sides. The average age was 35 (ranged from 17 to 55) years. There were 7 patients suffered from idiopathic ischemic necrosis of femoral head, 4 patients who had cannulated screws fixed after a femoral neck fracture, 4 patients who had a history of alcohol consumption, 1 patient who had taken corticosteroids for 6 months to treat nephritis, and 1 patient who had a history of alcohol consumption and had also taken corticosteroids. Seventeen hips were in Ficat stage II, and 4 hips were in Ficat stage III. The orthopaedic surgical robot workstation was used to plan the entry point and target of the guide pin during the operation, to place a cannula in the optimal position. Then a bone window was created and the fibula was placed into the bone tunnel.Using fluoroscopy to monitor each step of the procedure and verify the position of the fibula. Finally, the vessels were anastomosed. The patient remain in bed completely for a week with the use of vasodilator. The follow-up was accomplished with phone call and outpatient clinic, and Harris score was evaluated. Results All 21 surgical procedures were successful. The guide pins and fibula were accurately placed according to the robot’s plan, and the tips of the fibula were placed at the centre of the load-bearing region of the femoral heads, 4 to 6 mm from the articular surface. Conventional anticoagulant, anti-infective therapy was performed after the pro-cedure. Ten patients were followed-up postoperatively more than 1 year, with an average of 15 (from 12 to 24) months. The function of the hip joint recovered smoothly for 9 patients.Frontal and lateral X-ray and CT scans showed that the tips of the fibula were placed at the centre of the load-bearing region, 4 to 6 mm from the articular surface.One patient suffered from bilateral femoral head necrosis and the right side recovered smoothly after operation.However, joint move-ment was restricted for the left hip and the pain was significant.An arthroscopic examination was performed 1 month after the operation and did not identify any problems such as intraarticular incular infection or articular surface of the femoral head was protruded by the tip of the fibula.The symptoms were alleviated after removing the osteophytes at the rim of the acetabulum.The Harris score was 62.4±13.6 before operation, and 84.5±4.5 at the last time of followed-up after opera-tion.The difference in Harris scores was statisticly significant (P＜0.05). Conclusion With the assistance of an or-thopaedic robot system, the guide pin can be accurately positioned, thereby allowing the tip of the fibula to be inserted in-to the optimal anatomical position and maximising its mechanical efficacy.In theory, it is the best choice for performing fibular bone transplantation in ANFH.And the early effect of treatment is good.

OBJECTIVETo develop and evaluate a mouse model of nonalcoholic steatohepatitis (NASH) induced by a high-fat and high-fructose (HFHFr) diet.

METHODSSix-week-old C3H mice were randomly divided into groups for HFHFr diet experimental modeling, high fat-only (HF) diet controls, high fructose-only (HFr) diet controls, and standard chow (SC) diet controls. The standard HFHFr diet was modified so that it consisted of 76.5% standard chow, 12% lard, 1% cholesterol, 5% egg yolk powder, 5% whole milk powder, and 0.5% sodium cholate, along with 20% fructose drinking water. At the end of experimental weeks 4, 8, and 16, measurements were taken for the NASH-related parameters of body mass, serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), lipid profile, and wet liver weight (upon sacrifice). In addition, histological changes in the liver were evaluated by hematoxylin-eosin (HE) and oil red O staining. The significance of differences between groups was assessed by statistical analysis, using the

METHODSof t-test, Wilcoxon rank sum test, x2 test, F test or Fisher's test as appropriate.

RESULTSAs compared to the mice in the SC group at the corresponding time points, the mice in the HFHFr and HF groups showed significantly higher body mass and wet liver weight, as well as more extensive and robust lipid disposition in hepatic tissues as evidenced by oil red O staining. However, HE staining indicated that the HFHFr and HF groups had different degrees of macrosteatosis accompanied with intralobular inflammatory foci, with the former showing more remarkable NASH-related histological changes. Analysis at the end of week 16 showed that about 80% of the mice in the HFHFr group had developed NASH [nonalcoholic fatty liver disease (NAFLD) activity score (NAS): less than 5]. The levels of low-and high-density lipoprotein (LDL and HDL) cholesterol, as well as the levels of ALT and AST, were increased from the end of week 4 to the end of week 8 for the HFHFr and HF groups. At the end of week 16, the two groups differed in the extent of increase in total cholesterol and LDL and HDL cholesterol, with only the HFHFr group showing statistically significant changes. Specifically, at the end of week 16, the HFHFr group showed ALT levels of 108.5 +/- 93.34 U/L (F=5.099, P =0.005 vs. HF group: 44.30 +/- 35.71 U/L, HFr group: 46.70 +/- 17.95 U/L, SC group: 24.70 +/- 6.57 U/L), AST levels of 316.30 +/- 208.98 U/L (F=6.654, P=0.001 vs. HF: 132.12 +/- 75.43 U/L, HFr: 143.30 +/- 38.53 U/L, SC: 122.60 +/- 12.76 U/L), total cholesterol levels of 5.18 +/- 0.58 mmol/L (F=72: 470, P =0.000 vs. HF: 3.94 +/- 0.75 mmol/L, HFr: 2.30 +/- 0.50 mmol/L, SC: 2.02 +/- 0.24 mmol/L), HDL cholesterol levels of 3.05 +/- 0.49 mmol/L (F=25.413, P =0.000 vs. HF: 2.65 +/- 0.54 mmol/L HFr: 1.77 +/- 0.47 mmol/L, SC: 1.58 +/- 0.16 mmol/L), LDL cholesterol levels of 1.11 +/- 0.23 mmol/L (F =83.297, P =0.000 vs. HF: 0.72 +/- 0.17 mmol/L, HFr: 0.27 +/- 0.04 mmol/L, SC: 0.20 +/- 0.05 mmol/ L).

CONCLUSIONThe present study suggests that a mouse model of NASH can be successfully induced by a 16-week modified HFHFr diet.

Objective Using dynamic glucose monitoring system to investigate the influence of dynamic glucose excursion onthe serum cystatin C (Cys-C) in patients with type 2 diabetes mellitus (T2DM).Methods A total of 164 hospitalized patients with T2DM were selected in this study.All the patients underwent continuous 72 hours dynamic glucose monitoring.The parameters of glucose excursion were calculated,including blood glucose standard deviation (SD),and average blood glucose level (MBG).According to the monitoring results,the patients were divided into two groups:high blood glucose excursion groupand low blood glucose excursion group.Cys-C level and other biochemical parameters were detected.Then the correlation of SD and Cys-C was analyzedin the two groups.Results There were significant difference in age,urea nitrogen (BUN),serum uric acid (SUA),glomerular filtration rate (eGFR),and Cys-C levels between the two groups (P＜ 0.05).The mean value of Cys-C and the percentage of high Cys-C level were higher in high blood glucose excursion group than in low blood glucose excursion group.There was a positive correlation between SD and Cys-C (r=0.344,P＜0.01) in the whole group as well as in high blood glucose excursion group and low blood glucose excursion group (r=0.604,0.331,P＜0.01).The incidence of diabetic peripheral arterial disease(PAD),diabetic peripheral neuropathy(DPN),diabetic retinopathy(DR),DKD were higher in high blood glucose excursion groupthan in the low blood glucose excursion group.Multivariate stepwise regression analysis showed that WC,GA,FPG,FIns,SUA,eGFR,and SD were in dependent risk factors for Cys-C,and among them,SD had the greatest contribution(β=0.112,SE=O.025,P=0.000).Conclusion The dynamic glucose excursion is positively correlated with Cys-C in patients with T2DM.The greater the blood glucose excursion,the higher the Cys-C level.
