RESUMO
Objective:To evaluate the predictive value of proximal ureteral diameter (D1)to distal ureteral diameter (D2)ratio (DDR) for impacted stones in the middle and upper ureter.Methods:The clinical data of 173 patients with middle and upper ureteral calculi admitted to the Third Hospital of Shanxi Medical University from January 2014 to November 2021 were retrospectively analyzed. There were 75 males and 98 females, with the median age of 56.0 (51.0, 62.0) years old and median body mass index of 26.1 (24.8, 27.2) kg/m 2. The imaging data of the patients were analyzed. The impacted stones were defined as the inability of the contrast agent to pass through the site of obstruction when intravenous urography or CT urography was performed, resulting in the inability of the ureter to visualize normally in parts below the site of obstruction. D1 was defined as the proximal ureteral diameter at the lower pole of the kidney on horizontal CT images. D2 was defined as the ureteral diameter 3 cm from the calculi. The stone diameter, stone CT value, D1, D2, and DDR were compared between impacted stone group and non-impacted stone group. Univariate logistic regression analysis was used to analyze the different indicators. Random number table was used to divide the training set and validation set according to the ratio of 7∶3. Through least absolute shrinkage and selection operator(LASSO) regression analysis, the independent influencing factors were obtained and the nomogram model was established (Model 1). Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to verify the predictive efficacy of the model, and the other three effective models (Model 2-4) were constructed by stepwise multivariate logistic regression. The deLong test was used to compare whether there was a significant difference in the AUC between Model 1 and the other three models, and the net benefit of patients was analyzed by clinical decision curve analysis(DCA). Results:In this study, 64 cases (37.0%) were impacted ureteral calculi and 109 cases (63.0%) were non-impacted ureteral calculi, and there were significant differences in diameter[7.8(6.2, 8.8)mm vs. 6.3(5.2, 8.1)mm] , CT value[878.5(763.8, 940.5)HU vs.764.0 (613.0, 854.0) HU], D1[11.1(8.9, 14.9) mm vs. 9.1(7.1, 10.8) mm], D2[4.1(3.1, 4.9) mm vs. 5.0(4.1, 5.9) mm] and DDR[3.1(2.3, 3.9) vs. 1.8(1.4, 2.4)] between the two groups( P < 0.05). The results of univariate logistic regression analysis showed that stone diameter ( OR = 1.333, P < 0.001), CT value ( OR = 1.002, P=0.002), D1 ( OR = 1.146, P<0.001), D2 ( OR = 0.652, P < 0.001) and DDR ( OR = 2.995, P<0.001) were the influencing factors of impacted stones. The training set and validation set included 122 cases and 51 cases, respectively, without significant differences in their image characteristics and outcomes ( P > 0.05). The results of LASSO regression analysis showed that λ corresponding to the simplest result in the optimal range was 0.0908, and three variables were included at this time, and the influencing factors of impacted stones were stone diameter (coefficient 0.0700, OR = 1.073), CT value (coefficient 0.0003, OR = 1.001) and DDR (coefficient 0.5960, OR = 1.815). Moreover, Model 1 was established. According to the model fitting results, ROC curves were plotted, and the AUC of Model 1 was 0.862, and the AUCs of Model 2-4 were 0.859, 0.762, and 0.793, respectively. After deLong test, there was no significant difference between Model 1 and Model 2 ( Z = 0.248, P = 0.804). The AUC of Model 1 was superior to that of Model 3 ( Z = 2.888, P = 0.004) and Model 4 ( Z = 2.321, P = 0.020). The DCA suggested that Model 1 could improve the net benefit rate by up to approximately 21% of patients. Conclusions:DDR is the influencing factor of impacted ureteral calculi, and the model constructed by DDR, stone CT value and stone diameter can effectively predict the probability of impacted ureteral calculi in the middle and upper ureter.
RESUMO
Patients with castration-resistant prostate cancer (CRPC) who received a novel androgen receptor pathway inhibitor (ARPI) often show drug resistance in response to treatment. Tumors acquire androgen receptor (AR)-independent subtypes, so that cancer cells no longer depend on AR pathway to continue to grow. More and more studies have shown that after CRPC patients received ARPI treatment, some patients not only failed to achieve the clinical benefit but also experienced the evolution of tumor progression, that is, neuroendocrine prostate cancer (NEPC). NEPC is closely related to poor prognosis. So far, rare effective and reliable drugs have been found clinically to treat NEPC. This article aims to summarize the mechanism of NEPC and the molecular targets, and provide references for the diagnosis and treatment of NEPC patients.
RESUMO
Objective:To explore the feasibility of clinical application of the self-made double-lumen silicone bladder pressure catheter by nursing staff. To provide a basis and method for improving the success rate of bladder manometry catheter intubation in patients with benign prostatic hyperplasia, shortening the bladder manometry testing time for nursing staff, and reducing the cost of block polyetheramide resin material catheters commonly used in clinical practice.Methods:The silicone catheter was modified to make a double-lumen silicone bladder pressure measurement catheter and (traditional catheter) block polyetheramide resin material bladder pressure measurement catheter for simulated bladder pressure volume test for comparison test; 80 cases of prostate hyperplasia and long-term indwell patients with urinary catheters were separately tested for urodynamics using a dual-lumen silicone bladder manometry catheter and a traditional catheter, comparing the success rate of intubation, the convenience of catheter exhaustion and the cost of the two methods, and correlating the results.Results:There was no significant difference between the dual-lumen silicone bladder manometry catheter and the traditional catheter-filled bladder manometry test for bladder pressure volume measurement and detrusor muscle stability; the two catheters performed double-lumen urodynamic testing in 80 patients with benign prostatic hyperplasia, the one-time success rate of catheterization of silicone bladder pressure measurement catheter and the convenient rate of catheter exhaust were 93.75% (75/80) and 97.50% (78/80) respectively, which were better than traditional catheters 77.50% (62/80) and 87.50% (70/80). The difference between the two groups was statistically significant ( χ2 values were 7.312, 4.414, both P<0.05); the cost of the double-lumen silicone bladder pressure measurement catheter was (134.57 ± 23.58)RMB, significantly lower than that of the traditional catheter [(654.78 ± 56.87) RMB], the difference between the two groups was statistically significant( t value was -66.505, P <0.05). Conclusions:The dual-cavity silicone bladder pressure measurement catheter has a wide range of materials, simple manufacturing methods and low cost. The operation of clinical catheterization is simple and convenient, and it is feasible to replace the traditional urodynamic bladder manometry catheter for measurement. It can facilitate nurses to remove bubbles in the catheter in time, shorten the detection and debugging time, and improve the efficiency of nurses′ work, which is worthy of clinical application.
RESUMO
The occurrence and development of malignant tumors is closely related to the tumor microenvironment. Tumor-associated neutrophils (TAN) are important inflammatory cells in the tumor microenvironment. Studies have confirmed that TAN plays an important role in tumor growth, invasion, metastasis, pathological angiogenesis, and immunity escapes. TAN can be activated as an anti-tumor N1 type and a tumor-promoting N2 type. This article reviews the biological characteristics of TAN and the role of TAN in the malignant tumors and its mechanism.
RESUMO
Objective To investigate the expressions of metallothionein-2A (MT-2A), E-cadherin, interleukin-6 (IL-6), cyclin E, proliferating cell nuclear antigen (PCNA) and bcl-2 in prostate cancer tissues and their correlation with biochemical recurrence of prostate cancer. Methods Tissue specimens from 128 cases of prostate cancer who underwent radical prostatectomy in Shanxi Dayi Hospital from October 2012 to October 2017 were processed and transferred into tissue microarrays, the clinicopathological parameters of patients were also recorded. The expression levels of MT-2A, E-cadherin, IL-6, cyclin E, PCNA and bcl-2 were detected by immunohistochemical avidin-biotin complex (ABC) staining. The correlation between different molecular markers and biochemical recurrence of prostate cancer was analyzed. Results The biochemical recurrence rate of 128 patients with prostate cancer was 30.5％ (39/128). The biochemical recurrence rates of low-risk, intermediate-risk and high-risk prostate cancer patients were 14.8％(8/54), 38.7％(24/62) and 58.3％ (7/12), respectively. The risk classification and pathological T stage of patients with prostate cancer were associated with the expressions of MT-2A, cyclin E, IL-6 and E-cadherin (all P< 0.05). Multivariate Cox risk model showed that the high risk classification (HR= 1.81, 95％CI 1.56-2.19, P=0.042), MT-2A positive expression (HR= 2.01, 95％CI 1.08-3.15, P= 0.005), cyclin E positive expression (HR= 1.79, 95％CI 1.08-2.21, P= 0.042) and E-cadherin negative expression (HR= 1.92, 95％ CI 1.22-2.45, P= 0.020) were the independent risk factors for biochemical recurrence of prostate cancer. Conclusion The expression of MT-2A, cyclin E and E-cadherin may serve as independent predictors for biochemical recurrence of prostate cancer.
RESUMO
Objective To investigate the upregulation of long-chain non-coding RNA LINC01204 on the expression of glypican-5 (GPC5) gene in bladder cancer cells and its effect on the proliferation,migration and invasion of bladder cancer cells.Methods Quantitative real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of LINC01204 in 12 cases of bladder cancer tissues and paracancerous tissues,bladder cancer cell lines (BIU-87,T24,J82,5637) and normal bladder epithelial cell SV-HUC-1.The bladder cancer cells with the lowest level of LINC01204 were infected with lentivirus particles carrying LINC01204 (experimental group) or infected with negative control lentivirus particles (control group),and the expression of LINC01204 and GPC5 were detected by qRT-PCR in both groups of cells.Western blot was used to detect the expression of GPC5 protein in the two groups of cells.Cell counting kit-8 (CCK-8) and Transwell chamber assays were used to determine cell proliferation,migration and invasion.Results The expression of LINC01204 in bladder cancer tissues (0.773 ±0.063) was significantly higher than that in adjacent tissues (3.665 ± 0.330),with statistically significant difference (t =8.612,P ＜ 0.001).The expression of LINC01204 in bladder cancer cell lines BIU-87 (0.320 ± 0.034),T24 (0.515 ±0.056),J82 (0.644 ±0.039),and 5637 (0.147 ±0.018) were lower than that of normal bladder epithelial cells SV-HUC-1 (1.009 ± 0.077),with statistically significant difference (t =8.160,P＜0.001;t=5.179,P=0.002;t=4.221,P=0.006;t=10.890,P＜0.001).The expression of LINC01204 in 5637 cells was the lowest.The expression of LINC01204 and GPC5 mRNA in experimental group were significantly higher than that in the control group,with statistically significant difference [(11.000±1.028) vs (1.019 ±0.119),t =9.651,P＜0.001;(4.476 ±0.347) vs (1.046 ± 0.163),t =8.962,P ＜ 0.001],with statistically significant difference.Western blot showed that the expression of GPC5 protein was up-regulated.Compared with the control group,the proliferation ability of 5637 cells infected with LINC01204 in experimental group began to decrease significantly from the third day (0.686 ±0.044 vs 0.536 ±0.026,t =2.943,P =0.026).The number of migration cells in experimental group (118.300 ± 16.260) was significantly lower than that in the control group (208.200 ±22.930),with statistically significant difference (t =3.198,P =0.019).The number of cell invasion in experimental group (50.390 ±5.368) was significantly lower than that in the control group (97.480 ± 15.350),with statistically significant difference (t =2.896,P =0.028).Conclusions LINC01204 can upregulate the expression of GPC5 gene and inhibit the proliferation,migration and invasion of bladder cancer cells.Targeted therapy for LINC01204 is expected to become a new gene therapy method for bladder cancer.
RESUMO
Objective To evaluated the clinical efficacy of transurethral en bloc resection of bladder tumor with 2 μm laser in the high-risk elderly patients with bladder cancer under local anesthesia. Methods All of 64 high-risk elderly patients having underwent surgical treatment from April 2015 to October 2016 were divided into 2 groups,2 μm laser group(30 patients)and transurethral resection of bladder tumor(TURBT)group(34 group)according to surgical methods.The area and degree of pain was observed and recorded using visual analogue scales(VAS)during the 2 μm laser operation. The operation time,bladder irrigation time,catheter indwelling time,hospital stay,complications and 1-year cumulative recurrence rate were compared between 2 groups. Results The ASA grade in 2 μm laser group was higher than that in TURBT group and there was significant difference(P<0.05).During the 2 μm laser operation,the urethra pain was 53.33%(16/30),bladder pain was 20.00%(6/30), both urethra and bladder pain was 26.67%(8/30).The VAS scores were(2.50 ± 1.38)points,all the patients tolerated the pain in the 2 μm laser group.There was no significant difference in operation time between 2 groups(P>0.05).The bladder irrigation time,catheter indwelling time and hospital stay were shorter in 2 μm laser group than those in TURBT group:(40.00 ± 19.06)h vs.(56.47 ± 14.55)h,(4.33 ± 1.40)d vs. (5.65 ± 0.93) d,(4.13 ± 1.51) d vs. (6.24 ± 0.75) d,P<0.05 or<0.01. The overall incidence of complications was lower in 2 μm laser group than that in TURBT group:13.33%(4/30) vs. 64.71% (22/34),χ2=8.719,P=0.003.Compared with that of pre-treatment,the quality of life was higher after treatment in two groups,but there were no significant differences between the two groups.There were no significant differences in 1-year cumulative recurrence rate between the two groups after treatment (χ2= 0.496,P = 0.481). Conclusions Transurethral 2 μm laser treatment in bladder cancer under urethral surface anesthesia is safe and reliable for the high-risk elderly patients and complications are fewer than TURBT.The recent curative effect is satisfied.
RESUMO
Objective To analysis the clinical features,diagnosis,treatment and prognosis of adrenal eosinophilic tumor with low testosterone levels.Methods The clinical data of a 22 years old male patient with adrenal eosinophilic tumor and low testosterone levels was analyzed.Blood pressure was 151/88 mmHg.The patient got bilateral gynecomastia.His bilateral testicular was soft and became smaller,with short penisr.Endocrine examination results showed:Estradiol 666 pg/ml,Prolactin 19.08 ng/ml,Testosterone 0.18 ng/ml,follicle stimulating hormone ＜ 0.2 U/L.The CT showed the mass density of soft tissue in the left adrenal region with diameter 7 cm,which was inhomogeneous and enhanced.There were many small vessels enhanced in the CT arterial phase,and the blood flow in the tumor was abundant.Clinical diagnosis of left adrenal tumor was pheochromocytoma.The patient underwent laparoscopic left adrenal tumor resection.The left adrenal gland was located in the superior pole of the left kidney,and there was an independent supply of the artery.Results Pathological result showed the tumor weigh was 60 g,7 cm in diameter and brown in section.The tumor cells were arranged in solid nests or acini,with more eosinophilic granules in cytoplasm.The nuclei was round and the nucleoli was located in the center,had clusters of pleomorphic and clustered cells.The tumor was wrapped in a thick fibrous envelope,mainly consisted of eosinophils,granulation tissue.There was no necrosis,mitosis,and vascular invasion.Immunohistochemical staining showed that the expression of CD56 and syn protein was positive.Pathological diagnosis was left adrenal eosinophilic tumor.After 4 months,the blood testosterone levels rose to 3.90 ng/ml,the blood pressure returned to normal (118/75 mmhg).The estradiol (21 pg/ml) was significantly inhibited.The patient began to appear beards and breasts became smaller.There were no signs of clinical or imaging recurrence.After 16 months follow-up,serum testosterone was 4.68 ng/ml and serum estrogen levels dropped to 33 pg/ml.Semen routine showed no sperm.Conclusions The clinical morbidity of functional adrenocortical oncocytoma with low testosterone levels and high estradiol levels is low.The pathological components are mainly eosinophilic granulation tissue.The adrenocortical oncocytoma are rare and preoperative diagnosis is difficult.Clinical manifestation,imaging examination and adrenal biochemistry examination should be considered to determine the localization and qualitative of tumor.Minimally invasive surgery is an effective treatment.The close follow-up after operation is essential.
RESUMO
Objective To investigate the diagnosis and treatment of active adrenal tuberculosis.Method The clinical data of 1 patients with adrenal tuberculosis was retrospectively analyzed and the related literatures were reviewed.The male patient,54 years old,complained abuot the dry cough and intermittent fever for 9 months.He was found the left adrenal gland tumor for 1 weeks and admitted to our hospital on November 1st,2016.The physical examination showed the obvious left kidney percussion tellderness.The local hospital,considered the left adrenal tumor.The pathological diagnosis of left adrenal tumor by biopsy was chronic inflammation.The patient accepted anti-inflammatory therapy,but his symptom was not relieved.In our hospital,blood bacterial culture and urine bacterial culture and PPD was negative.Blood tuberculosis antibody was positive.Triple acid-fast bacilli were negative in urine.Chest CT did not exclude the interstitial pulmonary tuberculosis.Adrenal contrast-enhanced CT showed mild enhancement,strip calcification shadow.Primary diagnosis was left adrenal tumor,which the abscess and tuberculosis could not to be excluded.Then,the patient accepted regularly anti-tuberculosis therapy (Isoniazid,0.3 g/d,rifampicin,0.45 g/d,ethambutol,0.6 g/d).Mter 3 days,his temperature returned to normal.Since the left adrenal mass was too large,which was about 6.8 cm × 5.5 cm,to distinguish with the tumor,the patient accepted successfully retroperitoneal adrenal tumor resection two weeks later.The left adrenal tumor surface was greyish and yellow,which was adherent with spleen and pancreas.After carefully separating,the tumor was successfully removed.Result The operation was successful,which last 85 min.Intraoperative blood loss was about 50 ml.Pathological report showed adrenal tuberculosis.The patients accepted regularly antituberculosis therapy(Isoniazid,0.3 g/d,rifampicin,0.45 g/d,ethambutol,0.6 g/d) for half a year,and followed up for 1 year after operation.No further hormone replacement therapy was used.No fever was noticed and his rhythm cortisol level was normal.Conclusions Adrenal mass associated with recurrent fever,should be suspected as adrenal tuberculosis if antibiotic therapy is not effective.If the adrenal CT showed adrenal calcification associated with the ectepic tuberculosis,patient should be diagnosised active adrenal tuberculosis.They should accept anti-tuberculosis treatment.However,if the volume of tuberculosis is large,or not to exclude tumor possibility,we recommend to proceed adrenal tumor resection for diagnosis.

RESUMO
Objective To evaluate the safety and efifcacy of Laparoscopic partial nephrectomy (LPN) versus 1aparoscopic cryoablation (LCA) for the small renal tumors (SRMs).Methods The databases of PubMed, SCI, Ovid, the Cochrane Library, CNKI, CBM, VIP and Wangfang Data were searched to controlled clinical trial about LPN versus LCA for the treatment of small renal tumor. The retrieval time span was from inception to Apr 2016. The studies were screened according to the inclusion and exclusion criteria, the date were extracted and the quality was evaluated by 2 reviewers independently. And then the Meta-analysis was conducted using RevMan 5.3 software.Results 9 studies were included, and 748 cases were involved. The meta-analysis showed that comparing with LPN, the operation time of LCA was shorter [MD = 42.75, 95 % CI (12.19~73.31),P = 0.006], less intraoperative blood loss [MD = 190.73, 95 % CI (126.67~254.78),P = 0.000], shortening hospital stay [MD = 2.23, 95 % CI (0.17~4.28),P = 0.030], lower transfusion rate [OR
RESUMO
Objective To investigate the clinical and pathological features,diagnosis,differential diagnosis,treatment and prognosis of secondary Hodgkin's lymphoma of ureter.Methods We retrospectively analyzed one case with retroperitoneal Hodgkin's lymphoma involving right ureter.A 63-year-old male patient was referred to our hospital on January 22th,2013 with right hydronephrosis for 15 days,detected by abdominal color Doppler ultrasound due to constipation and difficult defecation without any urinary symptoms.Urinary CT scan revealed that there were dilation and hydrops of right pelvic and ureter in the middle and upper segment.The distal portion of ureteral wall was thick with a stenosis lumen.There was multiple larged lymph nodes surrounding the abdominal aorta.So,it was clinically diagnosed as right ureteral carcinoma with lymphadenopathy and right hydronephrosis.The patient was then performed ureteroscopic inspection under general anesthesia.There was too narrow to go through smoothly the proximal ureter when the ureteroscope ascended 15 cm.Then,the exploratory surgery of right ureter was subsequently undergone.During operation,periureteral nodular mass and thickened wall were seen in the distal segment of ureter.Then the ureter lesion was partially excised with 1 cm and fast frozen pathology was undergone during operation.The result suggested chronic inflammation of ureteral.A 6Fr double J stent was left in the ureter.Then,the ureter was closed by 3-0 monocryl suture.Results The final pathological diagnosis was retroperitoneal Hodgkin's lymphoma with the lymph node involving the right ureter.After 40 days,the patient manifested high fever,night sweat,general lymphoadenomegalies.So,the clinical stage was classified as stage Ⅱ EB and poor prognosis group.Then,the patient received regular chemotherapy according to the ABVD (pirarubicin 20 mg/m2,bleomycin 10 mg/m2,vinblastine 1.4 mg/m2,dacarbazine 375 mg/m2) regimen over 8 cycles.Finally the symptomatology and diagnostic reassessment (hemato-chemical examinations and PET/CT) showed a clinical complete recovery after the follow-up period of 3 months.The follow-up plan is ongoing.Conclusions Because secondary Hodgkin's lymphoma of ureter is rare with concealed onset feature,lacking of characteristic clinical manifestations,it is relatively difficult to achieve the diagnosis and differential diagnosis.Therefore,pathology and immunohistochemistry should be assigned to confirm the diagnosis.It is stressed that physicians should be aware of the possibility of malignant lymphoma when unexplained hydronephrosis and thickness of the ureteral wall are found clinically.Generally it has a good prognosis and combination therapy for the treatment is given priority to with chemotherapy.
RESUMO
Objective To study the expression of NF-κB and COX-2 protein in renal cell carcinoma, and to investigate the clinical value of it in the occurrence, progression and metastasis of renal cell carcinoma as well as the prognosis of patients. Methods 48 cases of renal cell carcinoma tissues and 5 cases of normal renal tissues were detected by using immunohistochemical method, and following up the patients who were included in the study. Then we analyzed the relationship between NF-κB and COX-2 protein level and clinic pathological parameters as well as the prognosis of patients. Resalts The expression of NF-κB and COX-2 protein were increasing in renal cell carcinoma, the protein levels were significantly different compared with that in normal renal tissues(P <0.05). There were significantly positive correlation between the expression of NF-κB protein and the clinic stages of renal cell earcinoma(P <0.05), but no correlation between the expression of COX-2 protein and them(P >0.05). There were significantly negative correlation between the expression of COX-2 protein and the pathological grades of renal cell careinoma(P <0.05), but no correlation between the expression of NF-κB protein and them (P>O.05). The survival rate of these patients whose expression of NF-κB protein were positive was significantly lower than those of negative expression of NF-κB protein(P <0.05), and there was opposite result for COX-2, but not significanfly(P >0.05). The expression of NF-κB and COX-2 protein in renal cell carcinoma had no significant correlation (P >0.05). Conclusion There may be relationship between the expression of NF-κB and COX-2 protein and the occurrence, progression of renal cell carcinoma, the expression of NF-κB may also have association with metastasis of renal cell carcinoma as well as the prognosis of patients. Detecting the expression of NF-κB and COX-2 protein may be useful in early diagnosis of renal cell carcinoma as well as prognosis evaluation of patients.
