Objective:To explore the factors influencing executive functioning after a brain injury and analyze the relationship between executive functioning and other cognitive functions.Methods:Forty-six brain injury survivors were given the Executive Function Performance Task (EFPT) assessment and the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA). The scores and time of the EFPT tasks, and the orientation, perception, visual motor organization, thinking, and attention and concentration results in the LOTCA were observed. Regression analysis compared the males and females, those younger and older than 40, those with more or less than 12 years of education, trauma and stroke survivors, as well as those with left, right and bilateral lesion to isolate the factors most influencing executive functioning.Results:The average EFPT score on the cooking task, the medication score and the total score of the young group were all significantly higher than those of the older group. Their telephone time, medication time and bill payment time were all significantly shorter. Those with more than 12 years of education had average scores on the cooking, bill payment and EFPT significantly higher than those with less than 12 years of education. The average bill paying and total EFPT scores of the brain trauma group were significantly higher than the stroke group′s averages. No significant differences were observed between the different genders or those with different injury sites. Age was the strongest predictor of total EFPT scores. Except for the medication scores, the average scores of the other three tasks and the total score of EFPT were moderately correlated with the visual motor organization, thinking, attention and concentration, and total LOTCA scores, with correlation coefficients ranging from 0.31 to 0.64.Conclusions:Older persons and those will less education tend to have worse executive functioning. Traumatic damage to executive functioning is more serious than that caused by stroke. Executive functioning is closely related to visual-motor organization, and to the ability to think, attend and concentrate.

Objective:To test the utility of monofilament cutaneous threshold testing among patients with impaired touch sensation caused by central nervous system injury.Methods:Thirty stroke survivors and 30 patients with spinal cord injury were recruited. Monofilament threshold testing and cotton wool tests were performed on the bilateral forehead, face, palms and dorsum of feet among the stroke survivors. Among those with a spinal cord injury both tests were performed on each side of the L 4, L 5 and S 1 vertebrae. One week later, all were retested. Intra-class correlation coefficients (ICCs) were used to quantify the test-retest reliability of the tests. Kappa values were calculated to determine the degree of agreement between them. Stepwise multiple linear regressions were evaluated to examine the relationship between touch perception thresholds and age, height, gender, type of injury and injured site. Results:①The ICC for the monofilament test was between 0.74 and 0.95, higher than that of the cotton wool test (ICC: 0.60 to 0.83). ②The kappa value between the monofilament and cotton wool tests was 0.550, indicating good agreement. ③The types of injury and injured sites were independent correlates of the touch perception thresholds, but there was no significant correlation between the touch perception thresholds and age, height, gender or group.Conclusions:The monofilament cutaneous threshold test has good test-retest reliability, better than the cotton wool test. Therefore, it may be useful as a tool for assessing impaired touch sensation caused by central nervous system injury.

Objective:To explore vibration, position and motion proprioception of the ankle joints after a stroke.Methods:Twenty-eight stroke survivors with impaired ankle proprioception were divided into a right-side stroke group ( n=18) and a left-side stroke group ( n=8). Twenty-two healthy volunteers constituted a control group. Vibration perception thresholds, passive and active joint angle resetting, and motion minimum thresholds were quantified among the stroke survivors on both the healthy and the affected side. With the controls the dominant and non-dominant sides were used. The differences in proprioception between the healthy volunteers and the stroke patients, between the affected side and the healthy side of the stroke patients, and between left- and right-side stroke patients were analyzed and compared. Results:Among the stroke survivors the vibration perception threshold on the affected side averaged (28.91±22.53)μm. The absolute difference in the perception of passive positioning was (5.49±5.39)° for 15° of plantar flexion and (4.48±3.89)° for 5° of dorsal extension. In active positioning plantar flexion was (5.23±4.34)° and for 30° of plantar flexion it was (3.26±1.73)°. The 5° dorsal extension error was (4.97±3.48)°. The motion perception thresholds between 20° of plantar flexion, 10° of plantar flexion and the neutral position were significantly higher, on average, than among the control group. The stroke group also had significantly higher motion perception thresholds than the control group.Conclusion:The vibration, position, and motion sense of the ankle joint on a stroke survivor′s affected side tend to be impaired, with the impairment of vibration and motion sensing tend to be more substantial. After stroke, there is also mild impairment of vibration, position and motion sensing in the healthy ankle joint. The impairment of proprioception caused by right cerebral hemisphere injury may be more serious than that caused by injury on the left.

Objective To explore the relationship between positive rate of de novo donor specific antibody (dnDSA ) and human leukocyte antigen (HLA ) mismatch after kidney transplantation and explore the impact of dnDSA upon long-term graft survival and rejection .Methods Retrospective analysis was conducted for clinical data of 101 kidney transplant recipients .Based upon HLA antibody and dnDSA ,they were divided into three groups of HLA-(n=70) ,dnDSA- (n=23) and dnDSA+(n=8) .Rejection and graft survival were recorded for evaluating the impact of dnDSA on rejection and graft survival and observing the differences among all groups .Results The mismatchs of HLA-A/B and HLA-DR were more frequent than HLA-and dnDSA-groups(P=0 .047 , P=0 .010)and graft survival was lower in dnDSA+ group than HLA-and dnDSA-groups (P=0 .001) .The rejection rate was higher in dnDSA+ group (62 .5％ ) than HLA- group (8 .57％ ) and dnDSA-group (8 .69％ ) . The difference was statistically significant (P=0 .013) . Pathological examination indicated microcirculatory inflammation (glomerulonephritis & trichodangiitis ) and damage (multilayer change of capillary basement membrane) occurred frequently in dnDSA + group and C4d remained positive . However ,scar ,arterial fibrosis or tubulointerstitial inflammation was not correlated with dnDSA . Conclusions HLA mismatch is correlated with dnDSA positivity . And dnDSA may reduce graft survival and enhance rejection rate . Rejection mediated by dnDSA is often accompanied by microcirculatory inflammation and C4d positivity .

Objective:To study the clinical characteristics and management strategies of late bleeding after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of 58 patients with post-pancreaticoduodenectomy hemorrhage (PPH) admitted to the Department of Hepatobiliary Surgery of the Second Hospital of Hebei Medical University from March 2018 to March 2022 were retrospectively analyzed, including 42 males and 16 females, aged (61.88±11.02) years old. According to the occurrence of intra-abdominal erosion factors (e.g., pancreatic fistula, biliary fistula, gastrointestinal anastomotic fistula, intra-abdominal abscess), patients were divided into the erosion group ( n=42) and non-erosion group ( n=16). All patients underwent standard lymphadenectomy. Clinical data including the PPH time-point, occurrence of rebleeding, and treatment outcomes were accessed. The management strategies of PPH in the two groups of patients were analyzed. Results:The PPH time-point in the erosion group and non-erosion patients was 8.00 (5.00, 19.25) d and 21.50 (12.75, 26.75) d, respectively ( P=0.001). PPH can occurred within one month after surgery in both erosion and non-erosion groups. In the erosion group, 31 cases (73.81%, 31/42) were treated by re-operation, two (4.76%, 2/42) by interventional radiology and nine (21.43%, 9/42) with conservative protocol, respectively. In the non-erosion group, five cases (31.25%, 5/16) were treated by re-operation, seven (43.75%, 7/16) by interventional radiology and four (25.00%, 4/16) with conservative protocol, respectively. The incidence of re-bleeding is higher in the erosion group [47.6% (20/42) vs 12.5% (2/16), P<0.05]. Clinical manifestations, sites and severity of bleeding, and treatment outcomes were also different in the erosion and non-erosion groups (all P<0.05). Conclusions:The occurrence of intra-abdominal erosion factors can affect the clinical characteristics and treatment strategy of late bleeding after laparoscopic pancreaticoduodenectomy. Surgery remains the treatment of choice for post-pancreaticoduodenectomy hemorrhage either as an urgent or last resort.

Objective To summarize the clinical experience of the application of bortezomib desensitization regime prior to secondary renal transplantation in a highly-sensitized recipient. Methods At 13, 10 and 6 d prior to secondary renal transplantation, one patient positive for donor specific antibody (DSA) was subcutaneously administered with bortezomib at a dose of 1.3 mg/m2 combined with a low dose of immunoglobulin. Postoperatively, immunosuppressive regime of tacrolimus (FK506), mycophenolat sodium and methylprednisolone was adopted. The serum creatinine (Scr), blood urea nitrogen (BUN) levels, FK506 concentration, DSA titre, C3d binding DSA (C3d-DSA) titre, pathological biopsy of the renal graft and adverse reactions were observed. Results During 12-month follow-up after administration of bortezomib, the Scr level was declined and maintained at 130 μmol/L, and the BUN level was remained at 3.9 mmol/L. The DSA level was significantly decreased and the C3d-DSA was negative. At postoperative 4 and 9 months, pathological biopsy of the renal graft revealed that the patient was positive for C4d, prompting the chronic active antibody mediated rejection (AMR). The patient presented with grade Ⅲ peripheral neuropathy. Conclusions Application of preoperative bortezomib desensitization regime can effectively down-regulate the DSA level in the recipient and avert the incidence of acute rejection in highly-sensitized patients undergoing secondary renal transplantation. Comprehensive treatment using bortezomib is recommended for preoperative desensitization in the highly-sensitized transplant recipients.

Objective:To explore the techniques and outcomes of pure laparoscopic native nephroureterectomy (LNUT) with ipsilateral allograft at a single position for upper tract urothelial carcinoma (UTUC) in renal transplant (RT) recipients.Methods:Clinical data were retrospectively reviewed for 12 renal transplant children undergoing native UTUC with ipsilateral allograft from January 2016 to December 2021.There were 4 boys and 8 girls.Complete LNUT was performed with bladder cuff resection at a single position via a transperitoneal approach.The interval between UTUC and RT was 12-146 months.There were 6 pelvic UCs and 6 ureter UCs.Results:All laparoscopic procedures were successfully completed without any serious perioperative complication.Postoperative pathological examination confirmed the diagnosis of urothelial carcinoma.And all surgical margins were negative.One patient experienced an elevation of creatinine after one cycle chemotherapy and normalized after withdrawing chemotherapy.The median follow-up period was (4-65) month.Two cases of contralateral native transitional cell carcinoma had radical nephroureterectomy two years later and another two cases underwent transurethral resection of bladder tumor one year later.One case died from tumor metastasis.The remainders had no tumor recurrence or metastasis during follow-ups.Conclusions:Complete single-position LNUT for UTUC with ipsilateral allograft is a safe and effective mini-invasive technique.Effectively avoiding the injury of allograft, it also offers the advantages of standard operation, minimal trauma, simple handling and enhanced recovery after surgery (ERAS).

Objective:To explore the relationship between new biomarkers in donor blood and delayed graft function after kidney transplantation and evaluate the clinical value of new biomarkers in the diagnosis of DGF (delayed graft function).Methods:For recipients of donor kidney transplantation from August 2016 to December 2017, blood samples were collected from operations of donor organ resection within 12 hours of the day. Enzyme-linked immunosorbent assay (ELISA) was employed for detecting neutrophil gelatinase-associated lipocalin (NGAL), L-type fatty acid binding protein (L-FABP), kidney injury molecule-1 (KIM-1) and interleukin-18(IL-18). They were divided into DGF and EGF (early graft function) groups according to the diagnosis of DGF. The inter-group differences of four new biomarkers were calculated. Receiver operating characteristic curve (ROC curve) was plotted for finding the best positive cutoff value and the sensitivity and specificity of new donor blood marker for diagnosing delayed graft function were calculated.Results:Among them, 8 had postoperative DGF and 62 had none. The overall incidence of DGF was 11.43%. The serum concentration of NGAL was 521.01±132.84 ng/ml in DGF group versus (299.99±100.03) ng/ml in EGF group ( P<0.001). The ROC curve was plotted. With a NGAL concentration >425.15 ng/ml, the sensitivity and specificity for diagnosing DGF were 87.5% and 90.3% respectively. The area under the curve (AUC) was 0.891. The serum concentration of IL-18 was (14.10±12.36) ng/ml in DGF group and (4.61±1.83) ng/ml in EGF group ( P=0.047). With a IL-18 concentration of >5.345 ng/ml, the sensitivity and specificity for diagnosing DGF were 100% and 64.5% respectively. The AUC was 0.914. No significant inter-group difference existed in serum L-FABP/KIM-1. The sensitivity of donor creatinine in the diagnosis of DGF was 62.5%, specificity 75.8% and AUC 0.692. Conclusions:With an excellent level of sensitivity and specificity, an elevated concentration of NGAL/IL-18 in donor blood is superior to traditional creatinine in the diagnosis of DGF after renal transplantation.
