Analysis of causal relationship between blood metabolites and prostate cancer by two-sample Mendelian randomization

Objective:To investigate the causal relationship between blood metabolite levels and the occurrence of prostate cancer by using two-sample Mendelian randomization method.Methods:Pooled data from public databases for genome-wide association analyses of blood metabolites and prostate cancer were selected,and inverse variance weighting(IVW)was used as the primary method for estimating the causal effects,while heterogeneity tests,gene multiplicity tests and sensitivity analyses were performed to assess the stability and reliability of the results.Results:A total of six known metabolites were found to potentially increase the risk of prostate cancer development(P<0.05),namely fructose,allantoin,5-hydroxytryptophan,potassium ketoisocaproate,glycyltryptophan,and 1-heptadecanoyl-glycerol-3-phosphorylcholine,with no heterogeneity or genetic pleiotropy found.Conclusion:Six known blood metabolites may be potential risk factors for prostate cancer development in European populations.

Treatment of fat-poor renal angiomyolipoma with ectopic blood supply by fluorescent laparoscopy:A case report and review of literature

BACKGROUND Renal angiomyolipoma and renal cell carcinoma are the most common benign and malignant tumors of the kidney respectively,and the preoperative differential diagnosis is crucial due to the wide difference in treatment methods.Fat-poor renal angiomyolipoma is a relatively rare type of in renal angiomyolipoma.Its fat imaging features are not obvious,and it is easily misdiagnosed as renal cell carcinoma.CASE SUMMARY We report the case of a 41-year-old man who complained of osphyalgia.Subsequent abdominal computed tomography scans revealed that a heterogeneous mass was seen in the lower pole of the right kidney,with the size of about 53 mm×47 mm.And showed two right renal arteries,with the mass supplied by an ectopic vessel from the abdominal aorta.Fluorescent laparoscopic blockade of the right renal heterotopic artery and partial nephrectomy was performed.Based on histological and immunohistochemical findings,the tumor was diagnosed as fatpoor renal angiomyolipoma.CONCLUSION The use of fluorescent laparoscopy can effectively help intraoperative management,and the fluorescence pattern provided by intravenous indocyanine green can help suggest the final diagnosis,effectively guide the surgical decisionmaking,and avoid preoperative imaging diagnosis leading to nephrectomy for benign renal tumors,through fluorescent navigation of tumor supply vessel precise block,minimize the loss of renal function.

Neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios alone or combined with prostate-specific antigen for the diagnosis of prostate cancer and clinically significant prostate cancer

Objective:We evaluated whether the blood parameters before prostate biopsy can diagnose prostate cancer(PCa)and clinically significant PCa(Gleason score[GS]7)in our hospital.Methods:This study included patients with increased prostate-specific antigen(PSA)up to 20 ng/mL.The associations of neutrophil-to-lymphocyte ratio(NLR)and platelet-tolymphocyte ratio(PLR)alone or with PSA with PCa and clinically significant PCa were analyzed.Results:We included 365 patients,of whom 52.9%(193)had PCa including 66.8%(129)with GS of≥7.PSA density(PSAD)and PSA had better the area under the curve(AUC)of 0.722 and 0.585,respectively with pZ0.001 for detecting PCa compared with other blood parameters.PSA combined with PLR(PsPLR)and PSA with NLR(PsNLR)had better AUC of 0.608 and 0.610,respectively with p<0.05,for diagnosing GS≥7 population,compared with PSA,free/total PSA,NLR,PLR,and PsNPLR(PSA combined with NLR and PLR).NLR and PLR did not predict PCa on multivariate analysis.For GS≥7 cancer detection,in the multivariate analysis,separate models with PSA and NLR(Model 1:PsNLRþbaseline parameters)or PSA and PLR(Moder 2:PsPLRþbaseline parameters)were made.Baseline parameters comprised age,digital rectal exam-positive lesions,PSA density,free/total PSA,and magnetic resonance imaging.Model 2 containing PsPLR was statistically significant(odds ratio:2.862,95% confidence interval:1.174-6.975,p=0.021)in finding aggressive PCa.The predictive accuracy of Model 2 was increased(AUC:0.734,p<0.001)than that when only baseline parameters were used(AUC:0.693,p<0.001).Conclusion:NLR or PLR,either alone or combined with PSA,did not detect PCa.However,the combined use of PSA with PLR could find the differences between clinically significant and insignificant PCa in our retrospective study limited by the small number of samples.

The origin of blood supply for cavernous hemangioma of the liver

OBJECTIVE: To investigate the origin of blood supply to cavernous hemangioma of the liver (CHL). METHODS: To observe the relation of cavernous hemangioma of the liver to the hepatic artery and portal vein, we performed serial selective hepatic arteriography in 22 patients. Five patients after ligation of the right hepatic arteries underwent portography and liver staining by in jection of methylene blue into the portal veins and 2 patients had hepatic specimens resected, which were made into a model cast by filling the hepatic veins (yellow) and portal venous branches (blue) with methyl methacrylate after vascular lavage. RESULTS: Serial selective hepatic arteriography showed that hepatic arteries and hemangioma were displayed simultaneously, and that hemangioma was supplied by one to numerous arterial branches. In the portal phase of portography, contrast medium failed to enter the tumor and the intrahepatic branches of the portal vein were pushed aside by the tumor; in the liver parenchymal phase, however, the tumor appeared to be a low-density area. Hepatic arteriography and portography revealed that the fistula between the artery and portal vein may not be existed. The liver stained with methylene blue showed that the normal hepatic parenchyma could be stained with deep blue; in contrast, the tumor was not stained at all. The casting specimens showed that the eroded tumor left a round vacant area because of its total shedding, and no blue stained branches of the portal vein extended into the tumor. CONCLUSION: Blood supply of CHL may originate from the hepatic artery.

Liver blood supply after a modified Appleby procedure in classical and aberrant arterial anatomy

Reported here are two cases of a modified Appleby operation for borderline resectable ductal adenocarcinoma of the pancreatic body, in one of which a R0 distal resection was attended to by excision, not only of the celiac axis, but also of the common and left hepatic arteries in the presence of arterial anatomic variation Michels, type Ⅷb. The possibility and avenues of the maintenance of the blood supply to the left hepatic lobe after surgical aggression of this kind are demonstrated employing computed tomography (CT) and 3-D CT angiography. Furthermore, both cases highlight all important worrisome aspects of pancreatic cancer resectability prediction.

Source of blood supply of liver cavernous hemangioma and sclerosis and embolization treatment

AIM To investigate the source of blood supply of carvenous hemangioma of liver (CHL) and provide a feasibile treatment for CHL via hepatic artery. METHODS Ⅰ. Origin of blood supply of CHL: portovenography, hepatic arteriography and portal vein staining were performed in 5 patients. Two casts of hepatic blood vessels from resected specimen were observed. Ⅱ. Clinical data: Among 75 patients (30 males, 45 females, aged 25～57 years with a mean of 37 4). 56 were of solitary type (44 on the right lobe, 12 on the left with 4 having intraparenchymatoma) and 19 were of multiple type (9 on the right, 2 the left, 8 whole liver). Twenty two patients were treated by sclerosis, 50 by embolization via hepatic artery and 3 were excised. RESULTS In 5 cases with portography, the contrast medium did not enter the tumor, the tumor appeared as low denty area and the intrahepatic branches of portal vein were pushed aside. In 5 cases with portal vein staining, the normal liver parenchyma was stained deep blue, and the tumor was not stained. The tumor area appeared as a round vacant cavity in 2 specimen casts. In 72 patients treated with sclerosis a or embolization via hepatic artery or through interventional method, the tumors diminished by 10%～30% in diameter and no tumors grew larger. CONCLUSION The blood supply of CHL originates from the hepatic artery. Tumors treated with sclerosis and emblization decreased in size or got fiberized.

Effect of warm bladder irrigation fluid for benign prostatic hyperplasia patients on perioperative hypothermia, blood loss and shiver: A meta-analysis

Objective:To find out whether warm bladder irrigation fluid can decrease the occurrence of perioperative hypothermia,blood loss and shiver in patients treated with benign prostatic hyperplasia(BPH).Method:A comprehensive literature review and meta-analysis that included randomized controlled trials(RCTs)related to temperature of irrigation fluid in the perioperative treatment for BPH was taken by researchers.The relevant literature were searched in Chinese database,such as Retrieval Chinese Journal Full-text Database,VIP Journal Database,Wanfang database,as well as in English search engine and database,including Embase,Cochrane and Medline till January 2018.The study quality was assessed by recommended standards from Cochrane Handbook(version 5.1.0).Results:A total of 28 RCTs and 3858 patients were included.The results showed that the incidences of shiver(risk ratio[RR]Z 0.32,95%confidence interval[CI]:0.28e0.36,p<0.001,I^2 Z 0%)and hypothermia(RR Z 0.36,95%CI:0.21e0.59,p<0.001,I^2 Z 67%)in the group of warm irrigation fluid were lower than the group having room-temperature fluid.Room-temperature irrigation fluid group caused a greater drop in body temperature compared to warm irrigation fluid group(p<0.001,I^2 Z 96%).We performed a narrative descriptive statistics only because of substantial heterogeneity.Conclusions:Warm bladder irrigation fluid can decrease the drop of body temperature and the incidence of hypothermia and shiver during and after the operation for BPH.Warm irrigation fluid should be considered as a standard practice in BPH surgeries.

Applied anatomical study of the vascularized ulnar nerve and its blood supply for cubital tunnel syndrome at the elbow region

Cubital tunnel syndrome is often accompanied by paresthesia in ulnar nerve sites and hand muscle atrophy. When muscle weakness occurs, or after failure of more conservative treatments, anterior transposition is used. In the present study, the ulnar nerve and its blood vessels were examined in the elbows of 18 adult cadavers, and the external diameter of the nutrient vessels of the ulnar nerve at the point of origin, the distances between the origin of the vessels and the medial epicondyle of the humerus, and the length of the vessels accompanying the ulnar nerve in the superior ulnar collateral artery, the inferior ulnar collateral artery, and the posterior ulnar recurrent artery were measured. Anterior transposition of the vascularized ulnar nerve was per- formed to treat cubital tunnel syndrome. The most appropriate distance that the vascularized ulnar nerve can be moved to the subcutaneous tissue under tension-free conditions was 1.8 ± 0.6 cm （1.1-2.5 cm）, which can be used as a reference value during the treatment of cubital tunnel syndrome with anterior transposition of the vascularized ulnar nerve.

Robotic assisted laparoscopic simple suprapubic prostatectomy--The Smith Institute for Urology experience with an evolving technique

Objective:Despite a multitude of minimally invasive surgical options available for benign prostatic enlargement,open simple prostatectomy(OSP)remains the standard for large prostates(typically greater than 100 g).OSP,however,is associated with significant morbidity.Recently,a few reports touting robotic application to simple prostatectomy have been published.Herein,we reviewed our series of robotic assisted laparoscopic simple suprapubic prostatectomy(RALSSP)and detailed modifications in our technique as our experience increased.Methods:All RALSSP cases performed between January 2013 and January 2014 were reviewed for demographics,pre-operative features,and perioperative outcomes.All parameters were tabulated and mean values were calculated.Student’s t-test was utilized with p<0.05 deemed significant.Details regarding surgical technique were reviewed and highlighted.Results:Fifteen patients underwent RALSSP during this period.Mean age of these men was 68.7 years.Mean body mass index(BMI)was 28.5 kg/m^2.American Society of Anesthesiologists(ASA)score was on average 2.6.Average International Prostate Symptom Score(IPSS)was 16.2 with the majority of men experiencing some adverse clinical sequela of such benign prostatic hyperplasia(BPH).For those patients not in retention,preoperative post-void residual(PVR)was 428 mL.All patients underwent successful RALSSP without need for conversion or need for blood transfusion.Mean estimated blood loss(EBL)was 290 mL.Five patients underwent other concurrent procedures(e.g.,cystolithotomy).Mean length of hospital stay(LOS)was 2.4 days and only five patients required continuous bladder irrigation(CBI)postoperatively.Postoperative PVR improved to a mean of 33 mL and IPSS improved to 4.5(p<0.001).No major complications were identified.Adaptation of low transverse cystotomy,utilization of a robotic tenaculum in the#3 arm with its control by a surgeon on a second console,and the utilization of mucosal advancement have all subjectively aided in performance of RALSSP and perioperative outcomes.Conclusion:RALSSP allows for feasible performance of prostate adenoma enucleation with low risk of blood transfusion,short LOS,and significant improvement in IPSS and PVR;all while maintaining a minimally invasive approach.The use of a robotic tenaculum controlled by the secondary console and the mucosal advancement facilitate excellent outcomes and may play a role in minimizing hematuria and need for CBI.

INVESTIGATION OF BLOOD SUPPLY OF BRONCHOGENIC CARCINOMA DERIVING FROM PULMONARY ARTERY

Microfil perfusion technique was used to investigate the blood supply of bronchogenic carcinoma deriving from pulmonary artery on 20 fresh specimens of lung cancer, including 11 squamous carcinoma, 6adenocarcinoma, 1 alveolar cell carcinoma and 2undifferentiated carcinoma cases. The results showed that the appearance and quantity of pulmonary blood supply of bronchogenic carcinoma depended on and changed with the site, activity,growth mode as well as the local condition of tumor nodules; pulmonary artery supplied blood to the Periphery of the tumor and its iunermost part as well; vessels from pulmonary artery in tumor nodules were generally less in number than those in the surrounding normal lung tissues around. The results suggested that the tumor blood supply from pulmonary artery should he evaluated comprehensively and dynamically; during interventional chemotherapy via pulmonary artery, patients should bc selected carefully and the catheter for infusion placed in suitable position so as to gain the best therapeutic effect.

Environmental Exposure to Lead as a Risk for Prostate Cancer

Objective To evaluate the possible role of environmental exposure to lead as a risk factor for prostate pathology in patients suffering from prostate cancer (PCA) and benign prostate hyperplasia (BPH). Methods Blood lead (BPb) level was determined in PCA and BPH cases using a graphite furnace Atomic Absorption Spectrophotometer and compared with those in a control group living in the similar socioeconomic environment. Results BPb was significantly higher in PCA and BPH cases than in normals (P<0.05). Blood levels of zinc and copper were significantly lower in PCA and BPH cases when compared with controls (P<0.05). In all the three groups, a statistically significant positive correlation between lead and thiobarbituric acid reactive substances (TEARS) measured as malondialdehyde, and negative correlation between blood lead and antioxidant GSH level, indicative of possible generation of reactive oxygen species, were also observed after adjusting for age as a possible confounders. However, positive association between blood lead and TEARS was relatively higher in PCA patients (r=0.77, P<0.05) than in BPH (r=0.32, P<0.05) and normal (r=0.30, P<0.05). Conclusion These results with limited power seem to suggest for the first time that environmental exposure of aging males to lead may be a risk factor for prostate cancer and/or benign prostate hyperplasia possibly through generation of reactive oxygen species and/or reducing the level of zinc which acts as a cellular growth protector.
