ABSTRACT
Objective:To analyze the clinical features and magnetic resonance imaging of non-malignant patients assigned to Prostate Imaging Reporting And Data System (PI-RADS) 5 score.Methods:We performed a retrospective review of 289 patients who underwent magnetic resonance ultrasound targeted combined system biopsy with PI-RADS 5 lesions in the First Affiliated Hospital of Nanjing Medical University between May 2019 and July 2021. The median age 72 (66, 77)years, median body mass index 24.4(22.3, 27.1)kg/m 2, median prostate volume (PV) 37.39(29.39, 48.86) ml, median PSA 22.24(10.91, 62.69) ng/ml, and median PSAD 0.53(0.30, 1.52)ng/ml 2 were recorded. According to the biopsy pathological results, all patients were divided into benign lesion group and prostate cancer group. PSA, PSAD, PV, and apparent diffusion coefficient (ADC) values were compared, and magnetic resonance imaging and clinical characteristics of patients with biopsy benign lesions were analyzed. Results:There were 11 cases (3.8%) with benign lesion and 278 cases (96.2%) with prostate cancer. The characters of 11 negative biopsy cases were displayed as follows: median age 69(66, 79)years, median body mass index 22.0(21.0, 25.5)kg/m 2, median PV 62.90(38.48, 71.96)ml, median PSA 5.55(2.99, 20.52)ng/ml, median PSAD 0.16(0.07, 0.24) ng/ml 2, median ADC 714.47(701.91, 801.26)×10 -6 mm 2/s, abnormal digital rectal and amination in 5 cases, smoking in 7 cases, and alcohol consumption in 4 cases. The median PV [62.90(38.48, 71.96) vs. 37.21(29.22, 47.82)ml, P<0.01], the PSA value [5.55(2.99, 20.52) vs. 23.53(11.14, 65.98)ng/ml, P<0.01], and the PSAD value [0.16(0.07, 0.24) vs. 0.58(0.31, 1.57)ng/ml 2, P<0.01] were significantly different between benign condition group and prostate carcinoma group. Benign condition group included 5 chronic prostatitis, 2 acute prostatitis (1 with focal adenocarcinoma), 2 granulomatous inflammation, and 2 tuberculous granulomatous inflammation. In 7 benign cases, PSA was less than 10 ng/ml, combined with frequent urination, urgency of urination and incontinence were founded. In 8 benign cases, the area of lesion was more than 50% of the total prostate area in the axial position and the imaging of magnetic resonance were diffused, with regular shape and uniform signal. The imaging of symmetrical distribution was in 6 cases. Conclusions:The benign condition with PI-RADS 5 lesions included chronic prostatitis, acute prostatitis, granulomatous inflammation and tuberculous granulomatous inflammation, among which prostatitis was the most common cause. The PSA value were less than 10 ng/ml in most benign cases, with symptoms such as frequent urination, urgency of urination and incontinence. The imaging of magnetic resonance were diffused, symmetrically distributed, with regular shape and uniform signal.
ABSTRACT
Objective:To compare the differences of prostate cancer (PCa) and clinically significant prostate cancer (CsPCa) positive rate and postoperative complications between transperineal cognitive prostate biopsy (COG-TPBx) and transrectal cognitive prostate biopsy (COG-TRBx) based on biparametric magnetic resonance imaging (bpMRI).Methods:The data of 276 patients undergoing prostate biopsy from January 2019 to June 2021 in the First Affiliated Hospital of Nanjing Medical University were retrospectively reviewed. 157 patients underwent COG-TPBx(TPBx group) and 119 patients underwent COG-TRBx (TRBx group). The average age [(66.39 ± 8.31) vs. (66.30 ± 8.42)years], body mass index (BMI) [(23.85±2.49) vs. (23.68±2.61) kg/m 2], PSA values [9.43(1.47-19.80) vs. 8.94(0.66-19.99) ng/ml], prostate volume [37.92(13.99-167.40) vs. 40.78(11.67-188.21) cm 3], PSA density [0.21(0.04-1.17) vs. 0.20(0.04-1.04) ng/(ml·cm 3)], and suspicious digital rectal examination [17.20% (27/157) vs. 21.10% (25/119) ] were not significantly different between TPBx group and TRBx group. The positive rate of PCa, CsPCa, as well as post-biopsy complications of the two groups were compared. Results:There were no significant differences in the positive rate of PCa [49.68%(78/157) vs. 47.06%(56/119), P=0.666] and CsPCa [38.22%(60/157) vs. 34.45%(41/119), P=0.520] between the two groups. In stratification analysis, TPBx group has a significantly higher positive rate of both PCa [54.69%(35/64)] and CsPCa[43.75%(28/64)] in apex zone than TRBx group[39.62%(21/53) and 20.75%(11/53), all P<0.05). Moreover, the postoperative complications were not significantly different in TPBx group compared to that in TRBx group [10.19% (16/157) vs. 12.61%(15/119), P= 0.567]. Conclusions:Our investigations revealed that the overall positive rate of PCa, CsPCa, and the complications were not statistically different between COG-TPBx and COG-TRBx. COG-TPBx has a significantly higher positive rate of both PCa and CsPCa in apex zone.
ABSTRACT
Objective:To explore the influencing factors of clinically significant prostate cancer (CsPCa) in patients with PI-RADS score 3.Methods:The data of 133 consecutive patients with the PI-RADS score 3 from January 2019 to December 2020 were retrospectively analyzed. All patients underwent 4-needle transperineal targeted biopsy and 12-needle systematic prostate biopsy (SB). The overall age was 66 (60-72) years, and the overall PSA value was 8.22 (5.95-11.41) ng/ml. All patients underwent multiparametric magnetic resonance imaging (mpMRI), and PI-RADS v2.0 score was 3. Patients were divided into two mutually exclusive groups: non CsPCa group and CsPCa group. The differences of lesion location, laterality, focality and sequence parameters of mpMRI between the two groups were compared, and multivariate binary logistic regression was used to analyze the independent predictors of PI-RADS score 3 in patients with CsPCa.Results:Biopsy results showed 57 cases of prostate cancer, including 41 cases of CsPCa, and 76 cases of non-prostate cancer. The detection rate of prostate cancer was 46.62 %(57/133), and the detection rate of CsPCa was 30.83 %(41/133). There were 41 cases in CsPCa group and 92 cases in non CsPCa group. There was no significant difference between CsPCa group and non CsPCa group in age [66 (58-70) years vs. 66 (60-72) years], body mass index [24.22 (21.82-25.71) kg/m 2 vs. 23.71 (21.99-26.12) kg/m 2], PSA [9.39 (6.35-12.55) ng/ml vs. 7.67 (5.83-10.51) ng/ml], abnormal rate of rectal digital examination [21.95% (9/41) vs. 9.78% (9/92)] (all P > 0.05). There was significant difference in PSAD [0.40 (0.16-0.65) ng/ml 2 vs. 0.17 (0.12-0.24) ng/ml 2] ( P<0.05). In MRI, PI-RADS=3 lesions were mainly located in the transitional zone [46.62 %(62/133)]. In CsPCa group, MRI lesions were located in peripheral zone in 16 cases, transitional zone in 19 cases, and both areas in 6 cases. There were 16 cases on the right, 15 cases on the left and 10 cases on both sides. The lesions were diffused in 19 cases and localized in 22 cases. In the non CsPCa group, 41 lesions were located in the peripheral zone, 43 in the transitional zone, and 8 in both areas. There were 26 cases on the right, 35 cases on the left and 31 cases on both sides. The lesions were diffuse in 56 cases and localized in 36 cases. There was no significant difference in lesion location, side and diffusion degree between the two groups ( P> 0.05). Compared with the non CsPCa group, the positive rate of all MRI sequences in CsPCa group was higher (82.93% vs. 40.22%, P < 0.001), the positive rate of T2 weighted imaging (T2WI) was higher (92.68% vs. 75.00%, P = 0.018), the positive rate of diffusion weighted imaging (DWI) was higher (90.24% vs. 56.52%, P < 0.001), the maximum diameter was larger[(0.67(0.30-1.19)mm vs. 0.48(0.20-0.62)mm, P < 0.001], and the apparent diffusion coefficient (ADC) was lower[0.70(0.61-0.87) vs. 1.10(0.86-1.50), P < 0.001]. Concurrently, PSAD and lesion ADC were important predictors of CsPCa in logistic regression model [mean 10 fold cross validation AUC: 0.78(95% CI 0.65-0.88)]. Conclusions:Most of the MRI lesions in patients with PI-RADS 3 were located in the transitional zone, and the MRI lesions in CsPCa were more obvious and diffusion limited. PSAD and ADC values are independent predictors for the diagnosis of CsPCa in patients with PI-RADS score 3, and the log 2PSAD-ADC prediction model is helpful to find CsPCa from patients with PI-RADS score 3 and protect patients from unnecessary biopsy.
ABSTRACT
Objective:To explore the optimal core numbers in targeted prostate biopsy (TB).Methods:The clinical data of 138 patients with prostate cancer diagnosed by six needle trans-perineal TB combined with system biopsy in the First Affiliated Hospital of Nanjing Medical University from October 2018 to March 2020 were retrospectively analyzed. Their age was (69.07 ± 7.97) years old, the PSA value was 9.15 (6.66, 12.95) ng/ml, the prostate volume was 35.01 (27.65, 43.27) cm 3and the PSA density was 0.25 (0.17, 0.36) ng/(ml ·cm 3). All patients accepted bi-parametric magnetic resonance imaging examination and had regions of interests (ROIs) with prostate imaging reporting and data system (PI-RADS) version 2.0 scores ≥ 3. The detective rate of prostate cancer (PCa), clinically significant PCa (CsPCa) and clinically insignificant PCa (CIPCa), along with the Gleason score upgrading rate after radical prostatectomy were compared between different numbers of prostate TB cores. Results:The detective rates for present PCa or CsPCa for the first 1-, 2-, 3-, 4-, 5- and 6-core TB were 74.64%(103/138), 85.51%(118/138), 94.20%(130/138), 98.55%(136/138) and 100.00%(138/138) compared with the total number of cores taken, respectively. The detective rates for CsPCa for the first 1-, 2-, 3-, 4-, 5- and 6-core TB were 67.52%(79/117), 77.78%(91/117), 88.89%(104/117), 93.16%(109/117) and 98.29%(115/117) compared with the total number of cores taken, respectively. Additionally, 20.72%(23/111) patients had Gleason score upgrade after RP. Compared with 6-core TB, the rates of postoperative upgrading for the first 1-, 2-, 3-, 4- and 5-core TB were 50.00%(44/88), 67.05%(59/88), 81.82%(72/88), 88.64%(78/88) and 95.45%(84/88), respectively. For the ROIs with PI-RADS score of 3, 4 and 5, the CsPCa detected by 5, 4 and 3 needles of TB were 95.00% (19/20), 94.92% (56/59) and 94.74% (36/38) respectively. Postoperative upgrading rates were 11.11% (2/18), 9.30% (4/43) and 7.41% (2/27) respectively.Conclusions:For ROIs with PI-RADS score of 3, 4 and 5, TB with 5, 4 and 3 cores respectively is enough to obtain higher diagnostic efficiency and accuracy.
ABSTRACT
Objective:To explore the efficacy of single-plane bi-parameter magnetic resonance imaging (bpMRI) in the diagnosis of prostate cancer.Methods:The clinical data of 343 patients who underwent transperineal template prostate magnetic resonance-transrectal ultrasound (MRI-TRUS) cognitive fusion biopsy at the First Affiliated Hospital of Nanjing Medical University from January 2020 to July 2021 were retrospectively analyzed, with median age of [65.0(59.0, 72.0)] years, median body mass index (BMI) of [24.1(22.2, 25.6)]kg/m 2, median prostate volume (PV) of [41.7(29.1, 53.3)]ml, median PSA[6.9 (5.5, 8.4) ng/ml], median PSAD of[0.17(0.12, 0.22) ng/ml 2], and abnormal rate of digital rectal examination (DRE) [6.4%(22/343)]. All patients underwent initial biopsy and bi-parameter magnetic resonance imaging (bpMRI) examination before biopsy, and the images were interpreted using prostate image reporting and data system version 2.1 (PI-RADS v2.1). The detection rates of prostate cancer and clinically significant prostate cancer (csPCa) were compared between single-plane bpMRI and bpMRI. When PI-RADS≥3 score, MRI results were positive; when PI-RADS ≤2 score, MRI results were negative. Results:In the single-plane bpMRI group, 121 MRI results were negative and 222 were positive. Positive patients included 95 with PI-RADS 3 score, 94 with PI-RADS 4 score, and 33 with PI-RADS 5 score. In bpMRI group, 141 MRI results were negative and 202 were positive. Among the positive patients, 67 patients with PI-RADS 3 score, 102 patients with PI-RADS 4 score, and 33 patients with PI-RADS 5 score. The detection rates of single-plane bpMRI and bpMRI for prostate cancer were 22.3% (27/121) and 15.6% (22/141) in MRI negative cases[22.3% (27/121) and 15.6% (22/141), P=0.17], and PI-RADS scores with 3 points [35.8% (34/95) vs. 44.8% (30/67), P=0.25], 4 points [89.4% (84/94)vs. 90.2% (92/102), P=0.85] and 5 points [90.9% (30/33) vs. 93.9% (31/33), P=1.00] showed no significant difference in stratification. The detection rate of csPCa in the single-plane bpMRI group and bpMRI group was significantly different in the MRI negative cases [7.4% (9/121) and 2.1% (3/141), P=0.04]. PI-RADS scores with 3 points [22.1% (21/95) vs. 29.9% (20/67), P=0.27], 4 points [80.9% (76/94) vs. 79.4% (81/102), P=0.80] and 5 points [84.9% (28/33) vs. 90.9% (30/33), P=0.71] showed no significant difference in stratification. Conclusions:For those suspected of prostate cancer patients with PSA 4-10 ng/ml and PI-RADS score ≥3, single-plane bpMRI or bpMRI examination has the same efficacy in term of the detection rate of prostate cancer and csPCa.
ABSTRACT
OBJECTIVE@#To investigate the clinical relevance of serum interleukin-2 receptor α (IL-2Rα) in patients with systemic lupus erythematosus (SLE).@*METHODS@#One hundred and seven SLE patients and 39 healthy controls with comparable age and gender were recruited at Peking University People's Hospital from January 2019 to December 2020. Complete clinical data in 107 SLE patients at baseline and follow-up were collected. SLE disease activity index 2000 (SLEDAI-2K) was used to assess the disease activity of the SLE patients. The serum level of IL-2Rα in the SLE patients and healthy controls was measured using enzyme-linked immunosorbent assay (ELISA). The association between serum IL-2Rα and clinical and laboratory parameters was investigated. Mann-Whitney U test or t test, Chi-square test and Spearman correlation were used for statistical analysis.@*RESULTS@#The serum IL-2Rα levels were significantly higher in the SLE patients [830.82 (104.2-8 940.48) ng/L], compared with those in the healthy controls [505.1 (78.65-1 711.52) ng/L] (P < 0.001). Association analysis showed that the increased serum IL-2Rα was positively associated with SLEDAI-2K scores and anti-nucleosome antibody (r=0.357, P < 0.001; r=0.25, P=0.027, respectively). Thirty-six of 107 (33.6%) SLE patients had lupus nephritis. Serum IL-2Rα levels were significantly higher in the patients accompanied with lupus nephritis [1 102.14 (126.52-8 940.48) ng/L] than in the patients without lupus nephritis [743.89 (104.19-4 872.06) ng/L] (P=0.032). The patients in the high IL-2Rα group had more lupus nephritis compared with those in the low IL-2Rα group (40.8% vs. 19.4%, P=0.031). Meanwhile, SLEDAI-2K scores were found significantly higher in the high IL-2Rα group than in the low IL-2Rα group [10 (3-21) vs. 7 (3-16), P=0.001]. With the improvement of disease activity in the SLE patients after conventional treatments, serum levels of IL-2Rα [1 119.1 (372.25-2 608.86) ng/L] in the week 12 decreased significantly compared with the baseline [1 556.73 (373.08-8 940.48) ng/L] (P=0.042).@*CONCLUSION@#Serum IL-2Rα may be used as a biomarker of disease activity in patients with SLE. There is certain correlation between serum IL-2Rα and renal involvement in SLE.

Objective:To explore the clinical application of robot-assisted laparoscopic single-position nephroureterectomy and bladder sleeve resection for upper urinary tract urothelial carcinoma (UTUC).Methods:The clinicopathological data of 15 UTUC patients admitted to Union Hospital of Tongji Medical College of Huazhong University of Science and Technology from October 2018 to May 2020 were retrospectively analyzed. There were 8 males and 7 females, with a median age of 58.6 (ranging 52.6-69.6) years, including 8 cases of renal pelvic cancer, 2 cases of upper ureteral cancer, 5 cases of middle and lower ureteral cancer.The tumor located on the left side in 5 cases and right side in 10 cases. All 15 patients underwent robot-assisted one-step transperitoneal nephroureterectomy and bladder sleeve resection by the same surgeon. The patients were placed in a 70° healthy side lying position with a 10° head lower and foot high position. After routinely dissecting the kidneys and controlling the renal hilum, we continued to dissect the ureter down to the orifice of the bladder. The lymph node dissection was performed when dissecting the kidney and ureter. Then the ureter was resected like a sleeve and the bladder was sutured. Observation indicators, such as operation time, blood loss, postoperative drainage tube and urinary catheter placement days, were recorded.Results:All 15 patients were successfully completed the operation in the same position and the same robot berth without conversion. The median operation time was 103 (ranging 82-185) min, and the intraoperative median blood loss was 60 (ranging 30-120) ml. The postoperative median drainage catheter placement time was 3 (ranging 2-5) d, the postoperative median hospital stay was 5 (ranging 4-7) d, and the postoperative urinary catheters were placed for 14 days. Postoperative pathological examinations of 15 patients showed UTUC without positive margins. The median follow-up time was 15 (ranging 10-30) months. All 15 patients survived. One patient was found a recurrence in the bladder after cystoscopy. There was no tumor progression after bladder tumor resection and bladder perfusion chemotherapy, and no tumor recurrence or metastasis was seen in the remaining 14 cases.Conclusions:Robot-assisted single-position transperitoneal nephroureterectomy for UTUC does not need to change patient position and robot berth, which effectively shortens the operation time, and achieves good tumor control effect. The short-term follow-up results were satisfactory.
ABSTRACT
Objective:To investigate the curative efficacy of radical prostatectomy (RP) for T 4 stage prostate cancer invading bladder neck. Methods:The clinical data of 22 patients with T 4 stage prostate cancer invading bladder neck treated with RP from April 2013 to March 2021 were analyzed retrospectively. The mean age of the patients was (64.09±6.33) years, and the preoperative blood PSA was 57.70(39.40, 68.56) ng/ml. Preoperative MRI or PSMA-PET examination revealed bladder neck invasion, including 16 cases (72.73%) of urinary retention. Clinical stage of T 4N 0M 0 accounted for 40.91% (9/22), T 4N 1M 0 accounted for 45.45% (10/22), and T 4N 1M 1 accounted for 13.64% (3/22). Preoperative patients were not treated with neoadjuvant endocrine or chemotherapy. Laparoscopic or robotic assisted laparoscopic radical prostatectomy and pelvic lymph node dissection were performed. Results:The 22 operations were successfully completed without conversion. The operation time was(184.27±34.82) min, the amount of intraoperative bleeding was (210.91±83.03) ml, the retention time of drainage tube was (4.73 ± 1.03) days, the recovery of gastrointestinal function took 3 (2, 3) days, and the postoperative hospital stay was (6.68 ± 1.39) days. Postoperative pathology showed that the Gleason score of 7 points accounted for 4.54% (1/22), 8 points accounted for 13.64% (3/22), and 9 points accounted for 81.82% (18/22). The positive rate of margin was 81.82% (18/22). Pathological stage of T 4N 0M 0 accounted for 22.73% (5/22), T 4N 1M 0 accounted for 63.64% (14/22), and T 4N 1M 1 accounted for 13.64% (3/22), of which extracapsular or seminal vesicle invasion accounted for 90.91% (20/22). The incidence of postoperative complications above grade 3 was 9.09% (2/22), and the rate of urinary control recovery after 3 months of surgery was 90.91% (20/22). 16 patients with preoperative urinary retention were able to urinate normally after operation. All patients were treated with adjuvant androgen deprivation therapy (ADT) with or without antiandrogens, and 13 cases (59.09%) were treated with adjuvant radiotherapy. The postoperative PSA value before adjuvant treatment was 2.53 (0.51, 5.44) ng/ml. The median survival time was not reached. Two patients died of prostate cancer at 71 and 84 months and one patient died of heart disease at 28 months. Conclusions:RP surgery could effectively relieve the condition of urinary retention with low incidence of operative complications. Although the positive rate of surgical margin is high, RP could be used as one of the treatment options for T 4 stage prostate cancer invading bladder neck, while the long-term effect is still needed to be further analyzed.
ABSTRACT
Objective:To detect the value of utilizing bpMRI in prostate biopsy in the detection of prostate cancer with PSA≤20ng/ml.Methods:The clinical data of 394 patients who underwent prostate biopsy in the First Affiliated Hospital of Nanjing Medical University from November 2017 to October 2019 were retrospectively analyzed. Of all the patients, 177 underwent modified systematic biopsy, named TRUS group, 217 patients accepted pre-biopsy bpMRI examination, undergoing modified systematic biopsy if Prostate Imaging Reporting and Data System (PI-RADS) score < 3 or MRI-TRUS cognitive fusion targeted prostate + systematic biopsy if PI-RADS score ≥ 3, named MRI group. The median age of TRUS group was 66 (61, 74) years old, prostate specific antigen (PSA) was 9.52 (7.26, 12.30) ng / ml, and prostate volume (PV) was 36.84 (28.95, 57.72)ml. The median age of MRI group was 66 (59, 72) years old, PSA was 8.84 (6.65, 12.16) ng/ml, and PV was 39.45 (29.25, 58.69)ml. There was no difference in above parameters between the two groups. The χ 2 test was used to compare the detection rate of prostate cancer and clinically significant prostate cancer (CsPCa) between the two groups. Results:There was no significant difference in the detection rates of prostate cancer between TRUS group and MRI group [51.41% (91/177) vs. 48.39% (105/ 217), P = 0.550], but the detection rates of CsPCa were significantly different [26.55% (47/177) vs. 36.41% (79/217), P = 0.037]. In patients with PSA ≤ 10 ng / ml, there was no significant difference in the detection rates of prostate cancer between the two groups [43.62% (41/94) vs. 43.08% (56/130), P = 0.936], but there was a significant difference in the detection rates of CsPCa [17.02% (16/94) vs. 28.46% (37/130), P = 0.047]. There was no significant difference in the detection rates of prostate cancer [60.24% (50/83) and 56.17% (48/87), P= 0.504] and the detection rates of CsPCa [37.35% (31/83) vs. 48.28% (42/87), P = 0.150] between the two groups. The total detection rates of the last two needles in TRUS group and MRI group were 23.16% (41/177) and 36.63% (86/217), respectively, with significant difference ( P=0.001); the detection rates of CsPCa in the last two needles were 11.86% (26/177) and 29.03% (63/ 217), respectively, with significant difference ( P < 0.001). In MRI group, the detection rates of prostate cancer in patients with PI-RADS score <3, 3, 4, 5 were 21.21% (7/33), 25.84% (23/89), 73.24% (52/71), 95.83% (23/24), respectively; the detection rates of CsPCa were 12.12% (4/33), 17.98% (16/89), 54.93% (39/71), 83.33% (23/24), respectively. Conclusions:In patients with PSA ≤ 20 ng / ml, prostate biopsy based on bpMRI may improve the detection of CsPCa, especially in patients with PSA ≤ 10 ng/ml.
ABSTRACT
Angioimmunoblastic T-cell lymphoma is a rare T-cell lymphoma. The clinical manifestations are not specific. In addition to the common clinical manifestations of lymphomas such as fever, weight loss, night sweats and lymphadenopathy, it may also have skin rashes, arthritis, multiple serous effusions, eosinophilia and other systemic inflammatory or immune symptoms. The lymphoma cells of angioimmunoblastic T-cell lymphoma originates from follicular helper T cells, and the follicular structure of lymph nodes disappears. In the tumor microenvironment, in addition to tumor cells, there are a large number of over-activated immune cells, such as abnormally activated B cells, which produce a series of systemic inflammation or immune-related symptoms. This disease is rare and difficult to diagnose. This article reports a 36-year-old female. She got fever, joint swelling and pain, skin pigmentation, accompanied by hepatomegaly, splenomegaly, lymphadenopathy, anemia and other multiple-systems manifestations. The clinical manifestations of this patient were similar to autoimmune diseases such as adult onset Still's disease, rheumatoid arthritis, and systemic sclerosis, which made the diagnosis difficult. At the beginning of the disease course, the patient got arthritis and fever. And her white blood cells were significantly increased. Adult onset Still's disease should be considered, but her multiple-systems manifestations could not be explained by adult onset Still's disease. And her arthritis of hands should be distinguished with rheumatoid arthritis. However, the patient's joint swelling could get better within 3-7 days, and there was no synovitis and bone erosion on joint imaging examination. The rheumatoid factor and anti-CCP antibody were negative. The diagnostic evidence for rheumatoid arthritis was insufficient. The patient's skin pigmentation and punctate depigmentation were similar to those of systemic sclerosis. But the patient had no Raynaud's phenomenon, and her sclerosis-related antibody was negative. The diagnostic evidence for systemic sclerosis was also insufficient. After 3 years, she was finally diagnosed with angioimmunoblastic T-cell lymphoma by lymph node biopsy aspiration. This case suggests that the clinical manifestations of angioimmunoblastic T-cell lymphoma are diverse, and some symptoms similar to immune diseases may appear. When the patient's clinical symptoms are atypical and immune diseases cannot explain the patient's condition, and further evidence should be sought to confirm the diagnosis.

Objective:To investigate the role of conjunctival impression cytology in the diagnosis of Sj?gren's syndrome (SS) and the immunological factors influencing conjunctival lesions.Methods:A total of 57 patients complaining about dry eye were collected, including 38 patients with primary Sj?gren's syndrome (pSS) and 19 patients with non-SS. Conjunctival impression cytology tests were performed for all patients, and they were scored by the Nelson method. Thirty-one patients with SS underwent serological tests such as autoantibodies, immunoglobulins, and complement. The correlation between the relevant data was compared using the t test and the rank sum test. Results:The Nelson grade ≥2 is the positive cut-off value for the diagnosis of SS. The sensitivity was 68.4%, and the specificity was 89.5%, and the area under the receiver operating characteristic curve (ROC) was 0.767. In patients with SS, there was statistical correlation between the results of conjunctival impression cytology and antinuclear antibody (ANA) ( χ2=4.664, P=0.031), anti-SSA antibody ( χ2=8.58, P<0.01), anti-SSB antibody ( χ2=6.13, P=0.013), anti-SSA-52 antibody ( χ2=6.48, P=0.011), immunoglobulin (Ig)G ( t=-4.344, P<0.01) and rheumatoid factor (RF) ( U=25.0, P<0.01). Conclusion:Con-junctival impression cytology has certain value in the diagnosis of SS and can be used to evaluate conjunctival lesions in SS. Serum ANA, anti-SSA antibody, anti-SSB antibody, anti-SSA-52 antibody, IgG, and RF levels are significantly associated with the degree of conjunctival lesions, and can be considered as an indirect evidence of conjunctival involvement in SS.

ABSTRACT
BACKGROUND@#Intensive therapy with disease modifying anti-rheumatic drugs (DMARDs) has been reported to improve the outcomes of rheumatoid arthritis (RA). However, real-world study on the effect of intensive therapy on RA sustained remission is still lacking. This study aimed to investigate the outcome of sustained intensive DMARD therapy (SUIT) for RA in a real-world 5-year consecutive cohort.@*METHODS@#Based on a consecutive cohort of 610 out-patients with RA, remission of RA was assessed in 541 patients from 2012 to 2017, by dividing into SUIT, non-SUIT, and intermittent SUIT (Int-SUIT) groups. Changes in the disease activity scores were evaluated by 28-joint disease activity score based on erythrocyte sedimentation rate (DAS28-ESR), 28-joint disease activity score based on C-reactive protein (DAS28-CRP), and clinical deep remission criteria (CliDR). Cumulative remission rates between different groups were compared using Kaplan-Meier curves and predictive factors of sustained remission were identified by univariate and multivariate logistic regression analysis.@*RESULTS@#The remission rates of the SUIT group decreased from 12.0% (65/541) to 5.6% (20/359) based on DAS28-ESR, from 14.0% (76/541) to 7.2% (26/359) based on DAS28-CRP, and from 8.5% (46/541) to 3.1% (11/359) based on CliDR, respectively, with a gradually decreasing trend during the 5 years. The SUIT regimen led to a significantly higher cumulative remission rate than non-SUIT regimen based on DAS28-ESR (39.7% vs. 19.5%, P = 0.001), DAS28-CRP (42.0% vs. 19.6%, P = 0.001), and CliDR (24.5% vs. 8.7%, P = 0.001). The cumulative remission rates of patients treated with SUIT regimen were significantly higher than those treated with Int-SUIT regimen based on DAS28-ESR (39.7% vs. 25.7%, P = 0.043) and CliDR (24.5% vs. 14.2%, P = 0.047), but there was no significant difference between the two groups based on DAS28-CRP (42.0% vs. 27.4%, P = 0.066). Multivariate logistic regression analysis showed that the use of SUIT regimen was an independent favorable predictor according to different remission definitions (for DAS28-ESR: odds ratio [OR], 2.215, 95% confidence interval [CI]: 1.271-3.861, P = 0.005; for DAS28-CRP: OR, 1.520, 95% CI: 1.345-1.783, P = 0.002; for CliDR: OR, 1.525, 95% CI: 1.314-1.875, P = 0.013).@*CONCLUSION@#Sustained intensive treatment of RA is an optimal strategy in daily practice and will lead to an increased remission rate.
ABSTRACT
OBJECTIVE@#To evaluate the effect of rosmarinic acid (RA) on mitophagy and hypertrophy of cardiomyocytes exposed to high glucose (HG).@*METHODS@#Rat cardiomyocytes (H9c2) exposed to HG (25 mmol/L) were treated with 50 μmol/L RA or with both RA treatment and Parkin siRNA transfection, with the cells cultured in normal glucose (5.5 mmol/L) and HG as the controls. The expressions of PINK1, Parkin and LC3II/LC3I in the cells were detected by Western blotting. The formation of mitochondrial autophagosomes was observed by transmission electron microscope. Flow cytometry was employed to detect the level of reactive oxygen species (ROS) and apoptotic rate of the cells. The activities of respiratory chain complex enzymes were measured by spectrophotometry. Fluorescence enzyme labeling and @*RESULTS@#RA treatment significantly increased the expression levels of PINK1, Parkin and LC3-II/I (@*CONCLUSIONS@#RA can protect rat cardiomyocytes against oxidative stress injury and cardiomyocyte hypertrophy induced by HG by activating Parkin-mediated mitophagy.

Objective:To investigate the use of bi-parametric magnetic resonance imaging (bpMRI)-based cognitive fusion targeted biopsy and systematic biopsy in patients with prostate imaging reporting and data system (PI-RADS)≥3.Methods:The clinical data of 220 patients with PI-RADS ≥3 who underwent bpMRI-transrectal ultrasound (TRUS) cognitive fusion targeted biopsy and systematic biopsy in the First Affiliated Hospital of Nanjing Medical University from May 2018 to November 2019 were retrospectively analyzed. The median age was 66 (60, 73) years old, median prostate specific antigen (PSA) was 8.73 (6.52, 11.93) ng/ml, medlian prostate volume was 39.25(29.26, 58.39) ml and the mean body mass index (BMI) was (24.02±2.60) kg/m 2. For each patient, bpMRI-TRUS cognitive fusion targeted biopsy and systematic biopsy were performed by two independent experienced urologists. The primary endpoint was the detection rate of CsPCa-A [clinically significant prostate cancer-A, defined as International Society of Urological Pathology (ISUP) grade group 2 or higher tumors]. The secondary endpoints were the detection rates of CsPCa-B (defined as ISUP grade group 3 or higher tumors) and CIPCa (clinically insignificant prostate cancer, defined as ISUP grade group 1 tumors). McNemar test and Chi-square test were used to compare the positive rates of CsPCa-A, CsPCa-B and CIPCa between targeted biopsy and systematic biopsy. Results:In this study, 112 patients (50.91%) were diagnosed with prostate cancer, and the detection was 42.73% (94/220) in targeted biopsy and 46.82% (103/220) in systematic biopsy.CsPCa-A was detected in 84 (38.18%) patients. Detection of CsPCa-A by targeted biopsy and systematic biopsy was not different significantly [30.00% (66/220) vs.34.09% (75/220), P=0.120]. CsPCa-A would have been missed in 8.18% (18/220) patients had not performed systematic biopsy, and in 4.09% (9/220) patients had not performed targeted biopsy. CsPCa-B was detected in 26.36% (58/220) patients. Detection of CsPCa-B by targeted biopsy and systematic biopsy was not different significantly [20.00% (44/220) vs. 23.18% (51/220), P=0.190]. CsPCa-B would have been missed in 6.36% (14/220) patients had not performed systematic biopsy, and in 3.18% (7/220) patients had not performed targeted biopsy. In addition, there was no difference in the positive rates of CIPCa between targeted biopsy combined with systematic biopsy, targeted biopsy only or systematic biopsy only [all three were 12.73% (28/220), P=1.000]. Nine post-biopsy adverse events were reported, including 5 cases of infection, 2 cases of vagal reflex and 2 cases of urinary retention. All of them were improved after symptomatic treatment. Conclusions:No significant difference was identified in the detection rate of CsPCa between targeted biopsy and systematic biopsy. However, combination of targeted biopsy and systematic biopsy could further improve the detection rate of CsPCa without increasing the detection of CIPCa. Therefore, a pre-biopsy bpMRI did have significant importance in the biopsy-na?ve patients, but did not seem to skip the need for systematic biopsy.
ABSTRACT
Objective:To investigate the difference of prostate cancer (PCa) detection rate between transperineal cognitive fusion targeted biopsy (COG-TB) and software fusion targeted (FUS-TB).Methods:We retrospectively analyzed 157 patients accepted transperineal targeted biopsies from December 2018 to December 2019, including 67 cases of COG-TB and 90 cases of FUS-TB. All patients were prostate biopsy na?ve, with PSA levels ≤ 20 ng/ml and prostate imaging reporting and data system version 2.1 (PI-RADS v2.1) scores ≥ 3. There was no significant difference between COG-TB and FUS-TB in the age [(70.78 ± 8.86) vs. (70.52 ± 8.79) years old], body mass index [(24.36 ± 2.69)vs. (24.14 ± 3.15) kg/m 2], prostate volume [36.69 (27.52, 47.40) vs. 38.81 (28.80, 53.46) cm 3], PSA level [8.27 (6.0, 11.65) vs. 8.88 (6.40, 13.54) ng/ml], PSAD [0.23 (0.15, 0.36) vs. 0.21 (0.14, 0.34) ng/ml 2], suspicious digital rectal examination findings [16 (23.9%) vs. 17 (18.9%)] and PI-RADS scores [24 (35.8%), 24 (35.8%), 19 (28.4%) and 21 (23.3%) vs. 21 (23.3%), 42 (46.7%), 27 (30.0%) for PI-RADS 3, 4, and 5, respectively]. There was no significant difference in baseline characteristics between the two groups (all P<0.05). The overall and stratified detection rates of PCa and clinically significant prostate cancer (CsPCa) were compared between the two groups. The upgrading rates of Gleason score after radical prostatectomy against biopsy Gleason score were compared between the two groups. Results:There was no significant difference between COG-TB and FUS-TB in the detection rate of PCa [76.1% (51/67) vs. 68.9% (62/90), P=0.32]. Also, no significant difference was found in the detection rate of PCa stratified by PSA [0-10ng/ml: 69.1% (29/42) vs. 57.1% (28/49); 10-20ng/ml: 88.0% (22/25) vs. 82.9% (34/41); all P>0.05] and PI-RADS score [3: 45.8% (11/24) vs. 23.8% (5/21); 4: 91.7% (22/24) vs. 81.0% (34/42); 5: 94.7% (18/19) vs. 85.2% (23/27); all P>0.05]. Similarly, there was no dramatically difference between COG-TB and FUS-TB in the detection rate of CsPCa [58.2% (39//67) vs. 50.0% (45/90), P>0.05]. No significant difference was found in the detection of CsPCa stratified by PSA [0-10ng/ml: 45.2% (19/42) vs.36.7% (18/49); 10-20 ng/ml: 80.0% (20/25) vs. 65.9% (27/41) ; all P>0.05] and PI-RADS score [3: 29.2% (7/24) vs. 9.5% (2/21), 4: 66.7% (16/24) vs. 57.1% (24/42), 5: 84.2%(16/19) vs. 70.4% (19/27) ; all P>0.05]. Additionally, the two technique was not different significantly in the upgrading rate [28.9% (13/45) vs. 26.2% (11/42), P=0.78]. Conclusions:There is no significant difference between FUS-TB and COG-TB in the detection rate of PCa and CsPCa, along with the upgrading rate after RP in patients with PSA ≤ 20 ng / ml and PI-RADS v2.1 score≥3.
ABSTRACT
OBJECTIVE@#To explore the clinical characteristics and outcomes of adult critically ill patients with COVID-19 and identify the risk factors correlated with in-hospital deaths.@*METHODS@#This study was conducted among 20 confirmed adult cases of COVID-19 in the Intensive Care Unit (ICU) of Honghu People's Hospital in Jingzhou City, Hubei Province. According to the final outcome, the patients were divided into survivor group and death group with 10 patients each. The demographic data, clinical manifestations and signs, laboratory findings, treatment measures and clinical outcomes were obtained from electronic medical records to compare the clinical characteristics and outcomes between the two groups. Univariate logistic analysis was used to analyze the risk factors associated with in-hospital death.@*RESULTS@#The mean age of patients with confirmed COVID-19 was 70 ± 12 years, and 40% of them were male. The patients were admitted to ICU 11 ± 9 days after symptom onset. The most common symptoms on admission were cough (19 cases), fatigue or myalgia (18 cases), fever (17 cases) and dyspnea (16 cases). Eleven (55%) of the patients had underlying diseases, among which hypertension was the most common (11 cases), followed by cardiovascular disease (4 cases) and diabetes (3 cases). Six (30%) of the patients received invasive mechanical ventilation and continued renal replacement therapy but eventually died. Acute cardiac injury was the most common complication (19 cases). Half of the patients died between the 2nd and 19th day after ICU admission. Compared with dead patients, the surviving patients had a lower average body weight (61.70±2.36 68.60±7.15 kg, =0.01) and a higher Glasgow Coma Index (14.69 ± 0.70 12.70 ± 2.45, =0.03), and were less likely to develop shock (2 10, =0.001) or acute respiratory distress syndrome (2 10, =0.001).@*CONCLUSIONS@#Critically ill patients with COVID-19 are generally older. A higher body weight and a lower lymphocyte count are potentially associated with a greater likeliness of fatality in ICU patients with COVID-19.

The prognosis of pancreatic cancer is very poor,40％-50％ of patients have liver metastasis at the time of initial diagnosis,and only 15％-20％ of patients have the chance of surgical resection.At present,there is no consensus on the treatment strategy of pancreatic cancer with simultaneous liver metastasis.Surgeons are still looking forward to surgical resection for patients with longer survival time.The application of neoadjuvant therapy and radiofrequency ablation may bring new breakthroughs in the treatment of pancreatic cancer with simultaneous liver metastasis.This article reviews the surgical,neoadjuvant and palliative treatment of pancreatic cancer with simultaneous liver metastasis.
ABSTRACT
Objective To investigate the causes and preventive measures for deviation of guide needle in orthopedics robot surgery.Methods A robotic surgery was simulated on a wooden stick.The guide needle was inserted under the guidance of the robot.A lateral deviation force was applied respectively onto the tail and tip of the needle.The actual offset distance at the guide needle tip was measured and compared with the 1mm offset allowed by robot monitoring.Results The offset distance of the guide needle tip was 0,5+0.07 mm when the deviation force was applied onto the tail,significantly smaller than the 1 mm offset allowed by the robot monitoring(l=22.588,P<0.001).The offset distance of the guide needle tip was 4.92+0.16 mm when the deviation force was applied onto the tip,significantly larger than the 1 mm offset allowed by the robot monitoring(t=17.416,P<0.001).Conclusions The deviation of guide needle may be caused chiefly by the deviation force onto the tip.As the actual offset distance of the guide needle tip may be larger than that shown on the robot monitor in orthopedics robotic surgery,the intraoperative monitoring should serve only as a reference to the deviation of the guide needle.The operative details may be the key to prevention of such deviations.
ABSTRACT
<p><b>Objective</b>To investigate the role of the serum inhibin B (INHB) level in evaluating the testicular function of the prepubertal patient with varicocele (VC) after high ligation of the spermatic vein (HLSV).</p><p><b>METHODS</b>This study included 31 prepubertal male patients with left VC, averaging 12.55 years of age and 9 complicated by right VC. We collected peripheral blood samples before and at 4, 12 and 26 weeks after HLSV as well as spermatic venous blood samples intraoperatively for determination of the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), anti-sperm antibody (AsAb) and serum INHB by ELISA.</p><p><b>RESULTS</b>Compared with the baseline, statistically significant differences were observed in the INHB level in the peripheral blood at 12 and 26 weeks after operation (［255.18 ± 69.97］ vs ［141.78 ± 59.82］ pg/ml, P < 0.05) and that in the spermatic venous blood intraoperatively (［255.18 ± 69.97］ vs ［412.44 ± 259.42］ pg/ml, P < 0.01). Spearman's analysis showed a negative correlation between the level of INHB and that of FSH (r = －0.224, P < 0.01).</p><p><b>CONCLUSIONS</b>The level of serum INHB in the peripheral blood of the prepubertal VC patient is decreased within 6 months after HLSV and negatively correlated with that of FSH. The levels of INHB and FSH may well reflect the testicular function of the prepubertal VC patient.</p>
