ABSTRACT
@#Objective To investigate visual impairment students' quality of life and its influencing factors in Braille learning class at Quanzhou Special School. Methods November, 2020, 52 students (aged seven to 26) with the best corrected distance visual acuity of the better eye above 0.02 were investigated with near visual acuity, contrast sensitivity and Chinese-version Low Vision Quality of Life Questionnaire (CLVQOL). The subjects were divided into second grade blindness group, first grade low vision group and second grade low vision group according to the best corrected distance visual acuity of the better eye. Results There were significant differences in distance visual acuity (Z = 45.671, P < 0.001), near visual acuity (Z = 24.972, P < 0.001), and contrast sensitivity (CS) ( Z = 13.285, P = 0.001) among three groups. There was a correlation between near visual acuity and distance visual acuity (r = 0.74, P < 0.001), CS to distance visual acuity (r = -0.58, P < 0.001) and near visual acuity (r = -0.57, P < 0.001), score of CLVQOL and CS (r = 0.44, P < 0.001). There were significant differences in the total score (Z = 10.145, P = 0.006), distance visual acuity subscale (Z = 13.586, P = 0.001), psychological adjustment subscale (Z = 7.824, P = 0.020), reading and fine work subscale (Z = 7.923, P = 0.019) of CLVQOL among the three groups. Conclusion Quality of life is different with the visual impairment for students in special school, especially the distance visual acuity, psychological adjustment and fine reading. CS correlates to the quality of life of visually impaired students, which needs to be a part of evaluation of visual function.

ABSTRACT
Objective To evaluate the growth and survival of single kidney transplants with donation after citizen death (DCD) donors from infants and children (＜3 years of age) to adults.Methods We retrospectively analyzed the data of single kidney transplants with donors from infants and young children to adults in our center.All the recipients were divided into infant donor group (≤3 years of age) and children donor group (1 year＜ age ≤3 years) in terms of the donor's age.The serum creatinine (SCr) level after surgery was determined and the major diameter of the kidney was measured by Doppler B ultrasonography.DGF,vascular complications,urinary tract complications,proteinuria,acute rejection,and infection were recorded during the follow-up period.Results There were 24 cases in infant donor group and 37 in children donor group.The mean follow-up period was 28 months.The SCr level at 1 st month post-transplantation was significantly higher in infant donor group than in children donor group (350.67 ± 35.57 μmol/L versus 193.70 ± 86.76 μmol/L),and the major diameter ((X-)± s) of the kidney in children donor group was significantly greater than that in infant donor group (78.29 ± 4.68 mm versus 93.62 ± 5.57 mm),but there was no significant difference during the subsequent 3-year follow-up period.The incidence of DGF in infant donor group was significantly higher than in children donor group,but there was significant difference in the rate of vascular complications,urinary tract complications,proteinuria,acute rejection,and infection between two groups.Conclusion The single kidney transplants from infants and young children to adults can grow rapidly,and their survival rate is relatively high.
ABSTRACT
Objective To compare the outcome of adult-to-adult single kidney transplantation from donation after drain death and cardiac death. Methods The outcome of adult-to-adult single kidney transplantation from October 2012 to September 2015 in kidney transplantation center of Zhujiang Hospital was retrospectively analyzed. 53 recipients received donation from donors after brain death (DBD group) and 28 from cardiac death (DCD group). The deadline of follow-up is May 2016. Results During the period of observation, the mean follow-up was (17.26±10.85) months and patient's survival rate was 100%. When compared graft survival rate with the two groups, survival rate is 93.7% in DBD group and 92% in DCD group (χ2= 0.184,P = 0.668). There was no statistically significant difference (P > 0.05), the overall incidence of DGF was 28.4%. General DGF incidence is 28.4%, and DGF incidence between groups is χ2= 4.402,P = 0.036. Infection rate within 1 year is χ2= 4.507,P = 0.034, and the difference is significant (P 0.05) in AR, eGFR of 1 month, proteinuria of 1 month after, transplantation and surgical complications. Conclusions Adult-to-adult single kidney transplantation from donation after cardiac death (DCD) has a higher rate of incidence of DGF, and the postoperative infection rate within 1 year. Renal transplantation from donation after cardiac death could have a good outcome.
ABSTRACT
Objective To observe the expression of MicroRNA-21(miRNA-21)in kidney tissue of unilateral ureteral obstruc-tion (UUO)rats and explore mechanisms of miRNA-21 involved in TGF-β1/Smad3 signaling pathway in renal interstitial fibrosis (RIF).Methods Totally 20 adult male SD rats were divided into UUO group and Sham operation group.The left ureter of rats in UUO group were ligated,and the rats in sham group were dissociated left ureter only,but not to be obstructed.The left kidney tis-sue was collected at the 3rd、7th days after surgery.Real-time quantitative PCR analysed the expression of miRNA-21.Masson stai-ning,HE staining and immunohislochemistry staining were used to evaluate the degree of RIF.The expression of transforming growth factor-β1(TGF-β1)、Smad3,α-smooth muscle actin (α-SMA)、and collagenⅠ(Col-Ⅰ)were examined by immunohislochemis-try staining.Results The expression of miRNA-21 in kidney tissue was higher at 3rd、7th days after surgery in UUO groups than that in Sham group(P <0.01).The expression in UUO group at 7th day was higher than 3rd day after surgery(P <0.01).The fi-brosis score,positive TGF-β1、Smad3、Col-Ⅰ、α-SMA area in UUO group were significantly higher than those of Sham group at 3rd、7th days (P <0.01),Which at 7th day were higher than 3rd day in UUO group(P <0.01).The expressions of miRNA-21 in kidney tissue was positive correlations with the fibrosis score(r=0.888,P <0.01).The expressions of miRNA-21 in kidney tissue was positive correlations with TGF-β1、Smad3、Col-Ⅰ、α-SMA(r=0.799,0.849,0.882,0.896,P <0.01).Conclusion The expres-sion of miRNA-21 was upregulated in UUO kidney tissue after model establishment.The RIF degree might be positive correlations with miRNA-21 expression,and TGF-β1/Smad3 signaling pathway positively regulate miRNA-21 to mediate rats RIF.
ABSTRACT
BACKGROUND:The rate of tuberculosis infection was high in patients after renal transplantation. Clinical manifestation is not typical, which brings inconvenience to diagnose. OBJECTIVE:To summarize the diagnosis and therapeutic methods of tuberculosis infection after al ograft renal transplantation. METHODS:Relevant diagnosis and therapeutic method of 13 patients with tuberculosis infection after renal transplantation were retrospectively analyzed in the Department of Organ Transplantation, Zhujiang Hospital of Southern Medical University from January 2010 to October 2013. RESULTS AND CONCLUSION:The onset time was 4-120 months after operation;62%(8/13) patients within 18 months after transplantation. Patients affected long-period fever, mainly low-grade fever. Four cases were identified according to the history, imaging data in combination with positive pathogenic diagnosis. Five cases were identified according to the history, imaging data combined with lung biopsy histopathology. The remaining four cases were identified according to the history, imaging data with experimental effective anti tuberculosis treatment. Early pulmonary symptom was not obvious. Chest CT was helpful in early diagnosis and differential diagnosis. Al patients fol owed early, law, ful , right amount, combined with principles of anti-tuberculosis treatment, and treatment usual y lasted for 6-10 months. They were given combined anti-tuberculosis infection drugs, adjustment of immunosuppressive agents and five-ester capsule for liver protection therapy. Thirteen patients were alive, no deaths. Two cases with early infection without timely treatment suffered from acute rejection, leading to loss of graft function and returned to hemodialysis. The others were cured and left hospital. Renal function was normal after 6-month fol ow-up (serum creatinine). Results indicated that after renal transplantation, patients with pulmonary tuberculosis should be early detected, early diagnosed and early treated. CT guided biopsy can be used as an effective and feasible means for diagnosis and identification of smear negative pulmonary tuberculosis after renal transplantation. Adjustment of immune scheme, anti-tuberculosis treatment and five-ester capsule significantly reduced calcineurin inhibitor dose, and lessened their adverse reactions.
ABSTRACT
Objective To describe the MRI features of vanishing white matter disease (VWM).Methods Ten patients diagnosed as VWM between 2008-2013 were enrolled,with the mean age of(40 ±23)months.The clinical materials and MR images of them were reviewed retrospectively.The findings of MRI were analyzed by two experienced neuroradiologists in this study,including the location (cerebrum,cerebellum,brainstem,corpus callosum and internal/external capsule),size and signal intensity of the lesions,as well as the presence of cystic degeneration,cerebrum atrophy and the abnormal signal of the basal nuclei.Results MRI of brain typically showed extensive abnormal signal in the cerebral central white matter (10/10) and the focal lesion in subcortical white matter (9/10).The involvement of U-fibers was present in 7 cases.Cystic degeneration of the affected white matter was found in 7 cases.Abnormal signal also appeared in the white matter of posterior limb of the internal capsule (8/10),the external capsule (7/10),the inner rim (the callosal-septal interface) of the corpus callosum (8/10).The lesions of the thalamus and globus pallidus were detected in 2 cases.The white matter of the brainstem and cerebellum were involved in 6 and 7 cases respectively.Conclusion VWM typically shows a diffuse and symmetrical abnormal signal in the cerebral white matter with cystic degeneration on MRI,which is usually diagnostic.
ABSTRACT
Objective To investigate the implication of nonspecific cellular infiltrates in biopsy of chronic allograft nephropathy and the prognosis.Methods Recipients indicated to renal biopsyproven CAN were analyzed from June 2007 to June 2009 retrospectively,and classified into three groups according to the Banff 2009 criteria:chronic active T-cell-mediated rejection (CTMR),chronic active antibody-mediated rejection (CAMR),interstitial fibrosis and tubular atrophy not otherwise specified (NOS).All the cases were followed up for 2 years.CD4,CD8,CD20 and CD3 expression,and C4d deposits were investigated.Results Eighty-three cases were enrolled in the study,diagnosed as having CTMR in 34 cases (40.9％),CAMR in 12 cases (14.6％),and NOS in 37 cases (44.5％).There was significant difference in total interstitial inflammation (ti),peritubular capillaritis (ptc) and C4d deposition among CTMR,CAMR and NOS groups.The number of CD4+ and CD8+ in CTMR group was increased as compared with CAMR and NOS groups.The 2-yeard renal graft survival in CTMR,NOS and CAMR groups was 73.5％,78.4％ and 41.7％ respectively.The prognosis in CAMR group was worst.Conclusion CAMR predicated a worse graft survival.Infiltration of CD4+ and CD8 + cells may help to make the diagnosis of CTMR.
ABSTRACT
Objective To study the effect of Alemtuzumab on acute rejection (AR) and graft survival after kidney transplantation.Method Published domestic and foreign literatures regarding the effects of Alemtuzumab used on acute rejection and graft survival were reviewed,and Meta analysis was employed to analyze the Results.Odds ratio (OR) and its 95％ confidence interval (95％ CI) were used as the parameters to evaluate the therapeutic effects.The statistical analyses were performed with RevMan 5.1 software.Result A total of 9 pertinent research articles were reviewed.Meta-analysis of pooled results indicated that Alemtuzumab prevented the recipients of kidney transplantation from acute rejection effectively with half year prevention of OR 0.37 and 95％ CI 0.24-0.58 (P＜0.01),one year prevention of OR 0.43 and 95 ％ CI 0.29-0.64 (P＜0.01),and two year prevention of OR 0.69 and 95％ CI 0.47-1.02 (P ＜ 0.01),respectively.It was revealed that Alemtuzumab could reduce the incidence of acute rejection by 55％ in half year,51％ in one year and 28％ in two years,respectively.No statistically significant difference in graft survival was found between Alemtuzumab group and control group (OR =1.18,95％ CI 0.76-1.85,P =0.46).No statistically significant difference in patients' survival was found between Alemtuzumab group and control group (OR =0.94,95 ％ CI 0.52-1.72,P =0.85).Conclusion Alemtuzumab may effectively prevent the recipients of kidney transplantation from acute rejection,but not obviously influence the graft and patient survival.
ABSTRACT
Objective To probe into effective surgical methods to reduce post-operational recurrence rate of nodular goiter.Methods One hundred and fifty-seven patients with nodular goiter who were admitted and had operations in our hospitals between Jan,2007 and June,2011 were assigned to one of the following 4 groups:total thyroidectomy(TT),nearly total thyroidectomy (NTT),subtotal thyroidectomy (STT),removal of lesion only or partial thyroidectomy (also termed as local removal,LR).Postsurgical recurrences and complications were compared among these groups.Results The recurrences were statistically analysed.There was a highly significant difference between TF and STT、TT and LR、NTT and LR; no difference was observed between TT and NTT,STT and STT + E,STT and LR.A statistical analysis was also carried out on the postsurgical compications in these patients.highly significant differnce was found between TT and STT,TT and NTT,TT and LR.There was a significant diffrence between STT and NTT.There was no difference between STT and LR,NTT and LR.Conclusion TT,STT,NTT are all effective operations for nodular goiter and should be advocated.Satisfactory efficacy may be obtained with oral thyroxine or euthyrox for postsurgical lifetime.However,LR or partial thyroidectomy should be adopted cautiously.
ABSTRACT
ObjectiveTo investigate the action mechanism of CD20 lymphocyte infiltration in the renal allograft biopsy with chronic allograft nephropathy (CAN).MethodsCAN cases confirmed by renal biopsy within 2 years after renal transplantation served as study subjects. By using immunohistochemistry,the deposition of C4d and the CD20-positive lymphocytes infiltration in the renal grafts were examined.The clinical follow-up data were analyzed.ResultsForty-four cases of CAN were enrolled in the study, including 13 cases (29.5％ ) of CD20-positive lymphocytes infiltration,and 31cases (70.5％ )of CD20-negative lymphocytes infiltration. CD20-positive lymphocytes in biopsy showed nodular and scattered lymphocytes infiltration.There were 5 (26.3％)cases of CAN Ⅰ,4 cases (25.0％) of CAN Ⅱ,and 4 (44.4％) of CAN Ⅲ in CD20-positive group.There was no statistically significant difference between the only CAN group and CAN with AR group in CD20-positive rate.Immunohistochemical staining showed there were 12 cases (27.3％) with C4d linear deposition in peritubular capillary endothelial cells (PTC).C4d positive rate had no significant difference among the CAN classifications. There was no significant relationship between C4d deposition and CD20-positive lymphocytic infiltration.The average serum creatinine in CD20-negtive group and CD20-posigtive group was 140.8 ± 22.0 and 183.5 ± 25.5μmol/L before biopsy,and 165.6 ± 37.6 and 242.2 ± 59.1 μmol/L one year after biopsy.The average serum creatinine level in CD20-positive group was higher than in CD20-negtive group before and after biopsy.ConclusionProgressive chronic humoral immunity is high risk in the process of CAN. The CD20-positive lymphocyte infiltration has no relevance with CAN grade and C4d deposition in PTC,but is associated with circulating antibody PRA and allograft long-term outcome. Pathogenetic mechanism may not contribute to chronic humoral immune,but B cells presenting donor antigens,are recognized and activated by T cells as antigen-presenting cells.
ABSTRACT
Objective Toobservetheindication, safetyandefficacyofanew immunosuppressant Rituximab in kidney transplantation. MethodsFive patients, who were diagnosed as antibody mediated rejection (AMR) from December 2010 to June 2011, were treated with single dose of Rituximab (500 mg) and followed up for 6 months. The clinical data, such as age, gender, onset of illness, induction therapy, maintaining therapy, allograft function, change of PRA, opportunistic infection and other complications were collected and retrospectively analyzed to evaluate the safety and efficacy of Rituximab used in AMR patients. ResultsAfter Rituximab therapy, all the patients had improved renal function measured by sera creatinine level: 4 cases retumed to normal, and 1 keep stable. Series of allograft biopsy demonstrated obviously reduced C4d deposition in nephridial tissue after treatment. One patient developed CMV viremia, another had urinary infection, but no one had lifethreatening infection during the follow-up period. The survival rate of human and allograft was both 100 ％. Conclusion Rituximab has a good efficacy and safety in treatment of AMR after renal transplantation.
ABSTRACT
BACKGROUND: It has reported that the combination of Tacrolimus and Wuzhi capsules can increase the peak concentration and area under curve of Tacrolimus recipients, however, the effects of this combination on recipients is poorly understood. OBJECTIVE: To investigate the effects of Wuzhicapsules on the blood concentration of Tacrolimus recipients. METHODS: A total of 38 renal transplantation recipients receiving triple therapy regime (Tacrolimus+mycophenolate +Prednisolone) were involved in the study and were divided into the experimental group (n=21) and control group (n=17). Recipients in the experimental group were taking Wuzhi capsules simultaneously, and those in the control group were not taking Wuzhicapsules. The Tacrolimus dosage to therapeutic concentration window and renal function were compared between the two groups at months 1,3 and 6 after transplantation. The incidence rates of acute rejection and diabetes mellitus, and renal and liver functions were observed at 6 months after transplantation. RESULTS AND CONCLUSION: The Tacrolimus dosage to therapeutic concentration window of the experimental group was significantly smaller than that of the control group (P < 0.05). However, incidence rate of acute rejection, diabetes mellitus, and renal and liver functions had no dramatically difference in 2 groups (P > 0.05). Results suggest that Wuzhi capsules may improve the immunosuppressive efficacy of Tacrolimus in renal recipients, therefore, can decrease the toxic effect of Tacrolimus with reduction dosage.
ABSTRACT
Objective To evaluate the efficacy of percutaneous transluminal angioplasty (PTA) in the treatment of transplanted renal artery stenosis (TRAS)-induced renal dysfunction and hypertension. Methods Between July 1998 and January 2007, PTA was performed on 16 patients with RTAS. Color Doppler uhrasonography preceded the intra-arterial angiographic investigation,with false-negative results in 18. 75 % of patients. Sixteen cases of TRAS were examined at 1 st week,6th month and 13 years after PTA. Hypertension improvement was defined as mean arterial pressure decrease of at least 15 % from the pre-PTA value. Graft function was evaluated by SCr levels, and the improvement was defined as a 20% change. Results Angioplasty was technically feasible in 100 %.Sixteen patients with RTAS were cured clinically. During the follow-up period, graft function was improved in 81.25 %, 68. 75 %, 62. 5 %, 56. 25 %, 50 % of patients respectively at 1st week, 6th month and 1-3 years after PTA. The blood pressure was decreased in 62. 5%, 75 %, 75 %,56. 25 %, 50 % of patients respectively, but no patient remained hypotensor medication free.Conclusion PTA improved renal dysfunction and hypertension induced by TRAS, and it is a safe and effective treatment for TRAS.
ABSTRACT
Objective To array the small intestine so that the uncontrollable adhesions will turn to controllable abhesions in order to prevent the intestinal obstruction. Methods Literatures were reviewed. The advance of plication of small intestine has passed through three stages: 1st, sewing the intestine just like the array of harpsichord keys; then, using straight needle with coarse threads to make a 'U' suture for the mesentery of small intestine so the intestine was arrayed, and 3rd inserting a Millers-Abbott tube into the lumen of small intestine followed by manual arrangement of the intestine. Results Using the Millers-Abbott tube the intestine was fixed in a steady position and arrayed in a half moon circular shape to avoid sharp angle. As a result, the intra-luminal pressure of the intestinal was effectively decreased. Follow up 45 cases showed the cure rate of 91.9%. Conclusion This operation has widely been accepted by the surgeons for its simplicity, high efficacy and reliability. It reduces the recurrence rate of adhesive obstruction.
ABSTRACT
AIM: To observe the effects of sodium restricted or supplemented on atrial natriuretic polypeptide (ANP) and cardiac function of rats with congestive heart failure (CHF).METHODS: CHF rats were divided into three groups with sham operation rats group as control. Radioimmunassay was used to determine the ANP contents of plasma and myocardium, at the same time cardiac function was measured.RESULTS: In sodium restricted group, the plasma sodium and atrial ANP and left ventricular systolic pressure and artery pressure were obviously lower than those in CHF group, while the plasma and ventricular ANP and the right atrial pressure were remarkably higher; In sodium supplemented group, the plasma sodium and arterial pressure had no obvious change compared with the control, the plasma and myocardium ANP and the right atrial pressure had no difference as compared with CHF group, while the left ventricular end diastolic pressure was remarkably lower and the left ventricular systolic pressure were obviously higher. CONCLUSION: Keeping the balance of plasma sodium by an appropriate supplement of sodium intake after CHF might be beneficial to the ANP biological effects and the cardiac function.
