ABSTRACT

Objective:To investigate the clinico-pathological characteristics and outcomes of adult patients with thin basement membrane nephropathy (TBMN).Methods:Patients with biopsy-proven TBMN in National Clinical Research Center of Kidney Diseases, Jinling Hospital during Jan 1, 2008 to Dec 31, 2017 were collected. The clinico-pathological characteristics, prognosis, the influencing factors of proteinuria and renal chronic lesions were retrospectively analyzed.Results:Among 135 adult patients included, 116 cases (85.9%) were female, and 19 cases were males. The age was (40.56±10.30) years old. There were 30 cases (22.2%) with hypertension and 32 cases (23.7%) with overweight or obesity. Proteinuria was found in 41 patients (30.4%) with (0.65±0.19) g/24 h of urine protein, and microscopic hematuria was found in all 135 patients. Serum creatinine was normal in all patients. Glomerulosclerosis was observed in 102 cases (75.6%), in which 51 cases (37.8%) had glomerulosclerosis>10%. There were 79 cases (58.5%) with mild chronic tubulointerstitial lesions, and 53 patients (39.3%) with vascular hyalinosis. The proportions of proteinuria, chronic tubular interstitial lesion and renal vascular lesion in patients with overweight/obesity and/or hypertension were higher than those without complications (all P<0.05). Multivariate logistic regression results showed that overweight/obesity ( OR=7.550, 95% CI 2.091-27.257, P=0.002) and hypertension ( OR=4.424, 95% CI 1.091-17.935, P=0.037) were independent influencing factors for proteinuria, while proteinuria was the independent influencing factor for chronic tubular interstitial lesion ( OR=3.151, 95% CI 1.046-9.491, P=0.041). Four patients were lost to follow-up, and the median follow-up time of the remaining patients was 64.0(24.0, 96.5) months. At the end of the follow-up, urine protein increased in 10 patients (7.4%) and estimated glomerular filtration rate decreased in 3 patients (2.2%). The above 13 cases were all complicated with overweight/obesity and 4 cases with hypertension. The urine test and renal function in the remaining 118 patients didn't change significantly from baseline. Conclusions:The incidences of proteinuria and renal chronic lesion are high in adult TBMN patients. Overweight/obesity and hypertension may cause a poor prognosis, and TBMN patients without metabolic abnormalities probably have good prognosis, but need long-term follow-up.

ABSTRACT

Objective:To evaluate the efficacy and safety of lenalidomide plus dexamethasone (LD) in patients with proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID).Methods:The clinicopathological data of PGNMID patients who were treated with LD protocol from January 2010 to October 2019 were retrospectively analyzed.Results:All of 6 patients received LD treatment for≥3 months after renal biopsy in Jinling Hospital. During the follow-up period of 6 to 19 months, 3 patients achieved renal remission, and the renal remission rate was 50%(3/6). Light microscopy showed membranoproliferative glomerulonephritis and immunofluorescence showed single kappa type IgG3 was deposited in the mesangial region and the vascular loop. Before taking LD scheme, the median urinary protein were 7.76(1.27, 14.57) g/24 h, the median serum creatinine was 118.5(70.7, 289.1) μmol/L, and the median albumin was 34.5(22.4, 37.5) g/L. The concentration of serum free kappa and lambda light chain was increased in 5 patients, but the serum free light chain ratio was normal. Hypocomplementemia was detected in two cases. Six patients underwent bone marrow flow cytometry, and 2 patients had elevated monoclonal plasma cells, accounting for 0.7% and 0.5%, respectively. Immunofixation electrophoresis suggested that 1 patient had positive serum M protein for kappa type IgG3. At the last follow-up, median urine protein was 3.33(0.33, 11.23) g/24 h, median serum creatinine was 108.7(80.4, 160.9) μmol/L, and median albumin was 35.9(24.5, 45.6) g/L. The concentration of serum free light chain in 4 patients from 5 patients with elevated serum free light chain was lower than that before taking the drug. Decreased level of serum complement in two cases returned to normal after treatment. The M spike did not turn negative during the follow-up in one patient. Adverse events included anemia, neutropenia, limb numbness and upper respiratory tract infection.Conclusion:This study reports for the first time that LD protocol may be effective in treating PGNMID, but more attention should be paid to the hematological adverse events of lenalidomide.

ABSTRACT

Diabetic retinopathy (DR) is one of the leading causes of vision loss and can be effectively avoided by screening, early diagnosis and treatment. In order to increase the universality and efficiency of DR screening, many efforts have been invested in developing intelligent screening, and there have been great advances. In this paper, we survey DR screening from four perspectives: 1) public color fundus image datasets of DR; 2) DR classification and related lesion-extraction approaches; 3) existing computer-aided systems for DR screening; and 4) existing issues, challenges, and research trends. Our goal is to provide insights for future research directions on DR intelligent screening.

ABSTRACT

Objective: To compare the risk angle and safety angle of needling Yamen (GV 15) between the atlanto-axial dislocation (AAD) patients and healthy subjects. Methods: A total of 177 AAD patients diagnosed and treated at the Center of Upper Cervical Vertebra of Beijing China-Japan Friendship Hospital between January 2010 and January 2018 were included in the AAD group. Another 207 healthy subjects were included in the normal group. There were totally 191 males and 193 females. The MRI scan was performed for the cervical vertebrae to measure the risk angle and safety angle of acupuncture at Yamen (GV 15) on the sagittal image. Results: In the AAD group, the risk angle was (13.14±3.99)° and the relative safety angle was (10.31±3.23)° for the perpendicular needling, while the oblique needling risk angle was (9.09±3.09)° for the male; the risk angle was (12.12±2.74)° and the relative safety angle was (10.56±2.09)° for the perpendicular needling, while the oblique needling risk angle was (9.70±2.95)° for the female. In the normal group, the risk angle was (7.89±1.59)° and the relative safety angle was (10.21±3.55)° for the perpendicular needling, while the oblique needling risk angle was (16.07±1.77)° for the male; the risk angle was (6.93±1.45)° and the relative safety angle was (10.70±2.94)° for the perpendicular needling, while the oblique needling risk angle was (14.89±2.18)° for the female. The perpendicular needling risk angles for the males and females in the AAD group were larger than those in the normal group, and the differences were statistically significant (bothP<0.01); for the inner-group comparison, there was no significant difference in the perpendicular needling risk angle between the male and the female in the AAD group (P>0.05); however, the perpendicular needling risk angle for the male was larger than the female, and the difference was statistically significant in the normal group (P<0.01). There were no significant differences in the relative safety angle for both the male and the female between the AAD group and the normal group (bothP>0.05). For the inner-group comparison, there was no significant difference in the relative safety angle between the male and the female (P>0.05). The oblique needling risk angles for both the males and females were smaller in the AAD group than those in the normal group, and the differences were statistically significant (bothP<0.01); the oblique needling risk angle for the male was not significantly different from that for the female in the AAD group (P>0.05); in the normal group, the oblique needling risk angle for the male was larger than that for the female, and the difference was statistically significant (P<0.01). Conclusion: Under the AAD condition, the risk angle and safety angle of acupuncture at Yamen (GV 15) change significantly, perpendicular needling should be better if performed slightly lower than the horizontal direction, and the oblique needling should be safer across the occipital foramen toward the occipital bone.

ABSTRACT

Objective@#To investigate the imaging features of cerebral small vessel disease(SVD) in systemic lupus erythematosus(SLE) patients with impaired renal function and their related risk factors.@*Methods@#Seventy-six SLE patients and forty age- and sex-matched healthy controls were recruited, and SLE patients were divided into the impaired renal function group [estimated glomerular filtration rate (eGFR) <90 ml/(min·1.73 m2)] (n=38) and the normal renal function group [eGFR≥90 ml/(min·1.73 m2)] (n=38) according to their eGFR. All subjects underwent brain MRI, cognitive and psychiatric testing. The SVD scores were measured, total white matter hyperintensity (WMH) and SVD scores were calculated, and the risk factors of SVD scores were analyzed by using ordinal logistic regression.@*Results@#SLE patients in the impaired renal function group showed higher basal ganglia PVS, centrum semiovale perivascular space (PVS), periventricular WMH, deep WMH and total SVD scores compared with normal controls or patients with normal renal function (H=44.568, 31.380, 31.172, 43.419, 24.317, P<0.001) . The ordinal logistic regression analysis showed that C-reactive protein was a risk factor for SVD in patients with SLE(OR=1.323, P<0.01).@*Conclusion@#SLE patients with impaired renal function had a higher SVD burden on MR imaging, particularly PVS in the basal ganglia and deep WMH, which was affected by the C-reactive protein level.

ABSTRACT

As more and more studies suggest that type 2 diabetes mellitus (T2DM) is closely related to male hypogonadism, people begin to pay more attention to the role of testosterone in the development of T2DM and the effect and safety of testosterone supplementary therapy. There is some controversy in randomized controlled studies and meta-analyses about the effects of testosterone supplementation on the blood glucose level, androgen deficiency symptoms, and cardiovascular diseases. This review focuses on the diagnosis of hypogonadism in T2DM males, differences in the therapeutic effects and safety of testosterone replacement among different studies, and rational use of testosterone supplementation for T2DM patients.

ABSTRACT

Objective To observe the effect of paraformaldehyde fixation on viscoelastic properties of the vertebrae in rats, so as to find the best methods of preserving cancellous bone samples from the perspective of biomechanics. Methods Twenty 8-week-old healthy female Sprague-Dawley rats were selected, and their whole L4 and L5 vertebra were separated by surgery. The total 40 vertebrae were randomly and evenly divided into experimental group and control group. The experimental group was fixed with 4% paraformaldehyde for 72 h, and the control group was transferred to 5 mL EP tube and cryopreserved at -20 ℃. Ten vertebrae were randomly selected from each group for stress relaxation and creep experiments. After 7 200 s, the samples were collected and their micro-structure changes were analyzed by micro-CT. Results The relaxation creep curve of experimental group was smoother than that of control group, the time to reach steady state was shorter, and the total amount of relaxation creep at 500 s and 7 200 s was significantly decreased (P<0.01). Micro-CT results showed that relaxation and creep experiment could cause trabecular rupture, and trabecular damage was more severe in experimental group than that in control group. Conclusions Paraformaldehyde significantly reduce the viscoelasticity of rat vertebrae, and it is more easily to cause microstructure damage under mechanical stimulation, which is detrimental to cancellous bone preservation.

ABSTRACT

<p><b>Objective</b>To compare the level of testosterone between type-2 diabetes mellitus (T2DM) patients and healthy controls and to investigate the status of hypogonadism and the influence of hypopgonadism on the quality of life.</p><p><b>METHODS</b>We collected serum total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG), and other clinical data from 166 T2DM patients aged over 30 years and 186 age-matched healthy controls. We investigated the quality of life (QoL) of the two groups of subjects using the questionnaires of Androgen Deficiency in Aging Males (ADAM), Aging Male Symptoms (AMS), 36-Item Short-Form Health Survey (SF-36), and Special Quality of Life for Diabetes Mellitus (DSQL).</p><p><b>RESULTS</b>The level of calculated FT (cFT) was remarkably lower in the T2DM patients than in the healthy controls (P<0.05), but no statistically significant differences were observed between the two groups in the levels of TT, bio-available testosterone (Bio-T), and SHBG. The T2DM males with hypogonadism showed significant differences from those without in age, height, systolic blood pressure, and creatinine (P<0.05). Based on the criteria of cFT <0.3 nmol/L and AMS score ≥27, the incidence rate of hypogonadism was 51.81% in the T2DM patients, 31.58% in the 30-39 yr group, 32.50% in the 40-49 yr group, 50% in the 50-59 yr group, 69.23% in the 60-69 yr group, and 77.27% in the ≥70 yr group, elevated by 77.4% with the increase of 10 years of age (OR = 1.774, P<0.001). The AMS score was significantly correlated with the scores of DSQL (r = 0.557, P<0.001) and SF-36 (r = -0.739, P<0.001) in the T2DM patients.</p><p><b>CONCLUSIONS</b>T2DM patients have lower levels of cFT than healthy men, accompanied with a higher incidence of hypogonadism. Age is a main risk factor of hypogonadism. Severer testosterone deficiency symptoms are associated with lower scores of QoL in T2DM males.</p>

ABSTRACT

Objective A prospective randomized controlled trial was carried out to explore the best time of In-domethacin suppositories administration for the prevention of post-ERCP pancreatitis in high-risk groups. Methods 81 patients were enrolled in the study finally. Patients were randomized into group A (100 mg rectal Indomethacin suppositories was administrated immediately after ERCP), group B (100 mg rectal Indomethacin suppositories was administrated half an hour after ERCP) and group C (ERCP alone group, which did not give Indomethacin supposito-ries). The level of serum amylase, urine amylase, serum CRP, serum IL-6, serum TNF-α were measured before, 3 h, 24 h and 48 h after ERCP, and the incidence of PEP and hyperamylasemia were analyzed. Results There was 1 case (4.00%) of PEP in group A, 2 cases (5.41%) of PEP in group B and 5 cases (26.31%) of PEP in group C;the incidences of PEP of group A and group B were significant lower than that in group C (P < 0.05). There was 1 case (4.00%) of hyperamylasemia in group A, 5 cases (13.51 %) of hyperamylasemia in group B and 6 cases (31.6 %) of hyperamylasemia in group C, and the incidences of hyperamylasemia of group A and group B were significant lower than that in group C ( P< 0.05). Conclusion Administration of 100 mg Indomethacin suppositories immediately or half an hour after ERCP can effectively reduce the incidence of PEP and hyperamylasemia.

ABSTRACT

Objective Neuropsychiatric systemic lupus erythematosus ( SLE) is a common complication of SLE, whose path-ogenesis is not yet clear but associated with the alteration of cerebral blood flow ( CBF) in some studies.This study was to investigate the CBF alteration in SLE patients without overt neuropsychiatric symptoms by arterial spin labeling ( ASL) MRI. Methods Twenty-eight SLE patients without overt neuropsychiatric symptoms and 30 age-and sex-matched healthy controls underwent conventional MRI and ASL examinations, and all received such neuropsychologic tests as number connecting test-A ( NCT-A ) , digit symbol test ( DST ) , self-rating anxiety scale ( SAS ) , and self-rating depression scale ( SDS) .Independent sample-t test was used to detect the mean CBF in the whole brain, gray matter, and white matter of the SLE patients and healthy controls.The voxel-wise CBF maps of the two groups of subjects were further analyzed with the SPM8 software to compare the regional CBF between the two groups, followed by evaluation of the correlation between the regional CBF values and clinical markers. Results In comparison with the healthy controls, the SLE pa-tients showed significantly reduced CBF in the gray matter (40.5 ±3.7 vs 37.3 ±6.5, P=0.028) and the whole brain (38.0 ±3.5 vs 35.1 ±6.1, P=0.032), especially in the supplementary motor area and the adjacent middle cingulate, anterior cingulate, left medial frontal gyrus, left inferior frontal gyrus, and left insula (P<0.05, FWE corrected).The NCT-A score was negatively correlated with the CBF values of the left medial frontal gyrus (r=-0.402, P=0.032) and left inferior frontal gyrus (r=-0.382, P=0.045) of the SLE patients. Conclusion ASL and MRI showed significantly reduced cerebral blood flow in the SLE patient without overt neu-ropsychiatric manifestations, which was correlated with the change of the patient's cognitive function.

ABSTRACT

Objective The treatment of anti-neutrophil cytoplasmic antibodies ( ANCA) associated vasculitis ( AVV) such as mycophenolate mofetil ( MMF ) can improve the remission rate, however, it also results in high recurrence rate and high incidence of adverse reaction related to the treatment.The article was to observe the clinical efficacy and safety of multi-target therapy ( MT ) in the treatment of AAV with renal involvement. Methods Retrospective observation was made on 7 AVV patients treated with multi-target therapy in our department from June 2009 to October 2013.The pa-tients (1 male, 6 females) aged from 21 to 54 years were accompa-nied with renal damage and serum creatinine (SCr≤3 mg/dL).All patients had positive myelopeeroxidase-ANCA (MPO-ANCA), high-grade proteinuria and hematuria.4 patients had elevated SCr (1.47-2.94 mg/dL) with EGFR90 mL/min in 2 patients and EGFR60 mL/min) .At the end of follow-up, the EGFR expres-sion was normal in 4 patients, 60-90 mL/min in 1 patient and less than 60 mL/min in 2 patients, without end stage renal disease. ANCA level turned to normal in 3 patients and significantly decreased in 4 patients.No patients had adverse reaction, died, or re-lapsed during the follow-up. Conclusion MT is effective in the control of renal activities of AVV patients with mild or moderate re-nal function damage.It attributes to great improvement of renal function and urine protein, as well as good tolerance.However, pro-spective study is required to confirm the efficacy of this new therapy.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the role of imatinib in induction therapy for newly diagnosed adult patients with Philadephia chromosome-positive acute lymphoblastic leukemia (Ph⁺ALL), as well as the status of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of adult Ph⁺ ALL in imatinib era.</p><p><b>METHODS</b>Retrospectively analyzed 97 newly diagnosed adult Ph⁺ ALL patients from 2005 to 2013. According to whether administrated imatinib in the induction therapy and the administrating duration (≥3 d) , they were divided into imatinib (n=37) and non-imatinib group (n=60), and the former group was further divided into early-use (n=26) and late-use imatinib groups (n=11) (bounded by the fourteenth day of induction chemotherapy). We compared the overall response rate (ORR) and the negative rate of BCR-ABL fusion gene in patients who achieved complete remission (CR) or CR with incomplete recovery of blood cells (CRi) among the three groups at the end of the first induction therapy. There were 44 cases underwent allo-HSCT (transplant group) and 33 cases only adopted imatinib-based chemotherapy (non-transplant group) in 77 patients who administrated imatinib as a maintenance therapy, we further compared the incidences of overall survival (OS) , disease-free survival (DFS), relapse and nonrelapse mortality (NRM) between the two groups; and dynamically monitor polymerase chain reaction (PCR) negativity of patients who were in CR1 state before transplant (n=34) at the following timepoints of achieving CR or CRi, the first consolidation therapy, beginning the pretreatment of transplant and attaining hematopoietic reconstruction after transplant.</p><p><b>RESULTS</b>After the first induction therapy, the ORR of imatinib group was significantly higher than of non-imatinib group (97.3%, 72.9% respectively, P=0.002), but early-use and late-use imatinib groups had no statistical significance in ORR (100% , 90.9% respectively, P=0.297); the rate of negativity of imatinib and non- imatinib groups were 20.0% and 0 respectively (P=0.041) in patients who achieved CR or CRi. The negative rate of patients in CR1 state before transplant attained 20.8%, 42.3%, 51.8%, 76.8%, respectively at the previously described 4 timepoints. And the differences between the fourth and the third, the third and the first timepiont all reached statistical significance (P=0.044, 0.022, respectively). The 5-year OS of transplant and non- transplant groups showed statistical difference (47.0%, 28.0% respectively, P=0.016), also for 5-year DFS (P=0.001) and the cumulative rate of relapse (P=0.000) of the former surpassing the latter; the cumulative rate of NRM between these two groups had no statistical significance (P=0.370).</p><p><b>CONCLUSION</b>Conventional induction chemotherapy in combination with imatinib in the first induction therapy of adult Ph⁺ ALL, not only improved the rate of hematologic remission, also the rate of molecular response. Imatinib used as a consolidation and maintenance therapy after remission, and allo-HSCT scheduled as soon as possible improved the prognosis.</p>

ABSTRACT

This study was purposed to investigate the engraftment, graft-versus-host disease (GVHD), transplantation related mortality (TRM), relapse and survival in hematologic patients received unrelated umbilical cord blood transplantation (UCBT). A total of 25 patients with hematological disease underwent UCBT, including 8 pediatric and 17 young adult patients. Among them 3 cases received single unit of UCBT and 22 cases received double units of UCBT. For donor/recipients human leukocyte antigen (HLA) matching: HLA 6/6 loci matched in 9 cases, HLA 4-5/6 loci matched in 16 cases. There were 19 patients with hematologic malignancies, including 3 cases in the period of disease progression and 6 cases of non-hematologic malignancies. Conditioning regimens were TBI/Cy ± Flu ± ATG or BuCy ± Flu ± ATG for 21 patients and Cy+Flu+ATG for 4 patients. For prophylaxis of acute graft-versus-host disease (aGVHD) the regimen of cyclosporine (CsA) as dominant drug was used. The results showed that among 16 patients (80.0%) achieved engraftment, 20 patients survived for more than 42 d after transplantation. The cumulative neutrophil recovery rate on day 42 after transplant was 64.0%, with a median time of 17.0 d;the cumulative platelet recovery rate on day 100 after transplant was 60.0 %, with a median time of 35.0 d. The cumulative rate of grade II-IV and III-IV aGVHD after transplantation 100 d was 44.0% and 30.7%, respectively. Until the end of the follow-up, the cumulative rate of TRM was 54.3%. For all the patients, overall survival rate was 42.7%. Out of 17 evaluable patients with hematologic malignancies 7 cases (41.2%) survived to date, and only 1 case relapsed, so event-free survival rate was 35.3%. Out of 5 evaluable patients with non-hematologic malignancies, 4 patients survived and 2 patients were in stable engraftment state, 2 cases with autologous hematopoietic recovery. Among 3 cases of hematologic malignancies at advanced stage, only 1 case survived to date. It is concluded that HLA-4-6/6 loci matched UCBT is an effective option to treat hematological diseases. Double cord blood transplantation (dUCBT) can overcome the disadvantage of insufficient cells of single cord blood UCBT to treat overweight children and adult.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the effect and the mechanism of Danhong Injection (DI), Ligustrazine Injection (LI), and adsorbable biomembranes in preventing the adhesion of tendons and tissues.</p><p><b>METHODS</b>Totally 120 patients all suffering from simple flexor digitorum tendon rupture on the hand zone two damaged by sharp weapons were randomly assigned to Group A (Dikang adsorbable biomembrane), Group B (Tianxinfu adsorbable biomembrane), Group C (Tianxinfu adsorbable biomembrane + Ligustrazine group), and Group D (Tianxinfu adsorbable biomembrane + DI group) in accordance with random digit table, 30 cases in each group. Indicators such as total active movement (TAM) of the hand tendon, Minnesota manual dexterity test (MMDT), and finger flex strength test (FFST) were observed.</p><p><b>RESULTS</b>The TAM and the favorable rate were higher in Group C and D than in Group A and B at post-operative 4 and 8 week (P < 0.05, P < 0.01). There was no statistical difference between Group C and D (P > 0.05). Each index of MMDT was lower in Group C and D than in Group A and B (P < 0.05). There was no statistical difference in FFST among all the 4 groups (P > 0.05).</p><p><b>CONCLUSIONS</b>Combined application of LI or DI with Tianxinfu adsorbable biomembranes could effectively prevent the adhesion of tendons. DI showed equivalent effect as LI did. Besides, the combined application was superior in preventing adhesion to using Xintianfu adsorbable biomembrane or Dikan adsorbable biomembrane alone.</p>
