Objective To explore the clinical utility of fluorescence in situ hybridization (FISH) urine test as a non-invasive method for diagnosing the upper urinary tract urothelial carcinoma (UUTUC).Methods Urine specimens from 30 consecutive patients with UUTUC were analyzed by means of FISH and cytology.Ultrasonic and CT were also used to analyze urine specimens from the study group.Urine specimens from 30 patients with other diseases were also analyzed by means of FISH and cytology in order to compare the specificity.Results The sensitivities of FISH,cytology,CT and ultrasonic were 87％,37％,90％ and 43％.The specificity of FISH and cytology were 97％ and 93％.The sensitivity between FISH and MMCT were compared and they were not statistically significantly superior to ultrasonic and cytology.FISH and cytology were compared and no specific statistical significance was found.The positive and negative predictive value for FISH was 96％ and 88％.For cytology it was 85％ and 60％.Conclusions FISH analysis is a useful ancillary test in the detection of UT-TCC with excellent sensitivity and specificity.It provides a more reliable and less invasive approach to diagnosis and postoperative follow-up for UT-TCC.

Objective To investigate the efficacy of retroperitoneal laparoscopic heminephroureterectomy for duplex kidney anomalies.Methods Retroperitoneoscopic heminephroureterectomy was performed on nine patients, six males and three females.The average age of the study group was 37 years ( range 13 to 58).Seven cases had anomalies on the upper kidney pole, two cases had anomalies on the lower kidney pole.Five anomalies were on the left side, two were on the right side and two were in bilateral sides (one special case had three ureters on the left side and two ureters on the right side ).Three cases complained of flank pain; two cases were found hydronephrosis by physical routine examination;Three cases complained of flank pain and fever; one cases complained of hematuria and kidney atones.All the cases were preoperatively diagnosed by color doppler ultrasound, MRU, IVP or CTU.Retroperitoneal laparoscopic heminephroureterectomy was performed on all patients.The operation time, blood loss, hospital stay, intraoperative and postoperative complications and efficacy were observed.Results All the retroperitoneal laparoscopic procedures were successfully completed.No intraoperative complications were found.The average operation time was 87 min (range, 65 to 125).The average blood loss was 112 ml (range, 30 to 600).The recovery times of intestinal function was 1.6 days ( range, 1 to 3 ).The average postoperative hospital stay was 7 days (range, 5 to 12).The syndrome disappeared and kidney function was normal at a mean followup of 18 monthes.Conclusions Retroperitoneal laparoscopic surgeries for duplex kidney has the benefits of being minimally invasive, fewer complications, quick recovery and certainty of efficacy.Retroperitoneal laparoscopic surgeries can be considered as a first operation method to treat duplex kidney anomalies.

ObjectiveTo investigate the efficacy of transurethral resection and ball pouch dilatation for treatment of ureterostenosis.MethodsThe clinical data of 49 cases of ureteral stricture were analyzed retrospective analysis from June 2008 to June 2011 with 20 cases of male patients and 29 cases of female patients.The age was 15 to 56 years,with a mean age of 40 years.Ipsilateral renal function were mild impairment in 4 cases,moderate impairment in 35 cases,and severe damage in 10 cases.There were ureteropelvic junction etenosis in 11 cases,upper ureteral stricture in 13 cases,and lower segment stenosis in 25 cases.The ureteral stricture length was 0.3 to 2.0 cm,with a mean of 1.2 cm.Seventeen patients were treated with transurethral resection and ball pouch dilatation by minimally invasive percutaneous nephrostomy,and 31 cases were completed by ureteroscopy.The ureteral stents were removed by ureteroscope after 3 - 6 months.45 cases were followed up for 12 -43 months,with a mean of 24 months. ResultsForty-eight cases were completed smoothly with 1 case converted to open surgery.The surgical time was 25 to 95 min with a mean of 42 min.The postoperative hospital stay was 2 to 6 d with a mean of 4 d.In the follow-up of 45 cases,B ultrasound and CT scan showed hydronephrosis reduced significantly in 39 patients,IVU showed unobstructed ureter without significant stenosis.And 6 cases showed no significant changes in hydronephrosis. Conc(t)usionThe method of transurethral resection and ball pouch dilatation has good clinical effect,less pain and shorter hospital stays,which provides a new and effective treatment for patients with ureteral stricture.

Objective To investigate the serum levels of semaphorin 3E(Sema3E)in patients with intracranial aneurysms,revealing the correlation between Sema3E and 1-month poor prognosis after interventional embolization.Methods This study was a prospective single-center cohort study,recruiting 102 consecutive patients with intracranial aneurysms who underwent interventional surgery from June 2020 to January 2022 in our hospital.Among them,11 patients were excluded.Clinical and radiological profiles were collected.Peripheral blood was collected after admission,and serum Sema3E levels were determined by enzyme-linked immunosorbent assay.All the aneurysms were treated with endovascular coil embolization or stent-assisted coil embolization.The primary outcome was evaluated with the Glasgow Outcome Scale(GOS)1 month after interventional therapy.The favorable outcome was defined as a GOS score of 4-5,and a poor outcome was defined as a GOS score of 1-3(severe disability,vegetative state,or death).Univariate and multivariate logistic regression analyses were used to identify potential prognostic factors after interventional therapy.Results The average age of 91 patients with intracranial aneurysm was 59.9±11.0 years old,including 70 cases(76.9%)with favorable prognosis and 21 cases(23.1%)with poor prognosis.The mean preoperative Glasgow Coma Scale(GCS)score of the poor prognosis group(9.4±4.5)was significantly lower than that of the favorable prognosis group(13.3±2.5;P<0.001).In the poor prognosis group,the Hunt-Hess grade(3.6±0.6 vs.2.0±1.3,P<0.001)and the serum Sema3E levels[(6.21±1.58)μg/L vs.(4.38±1.77)μg/L,P<0.001]were significantly higher than those in the favorable prognosis group.Logistic regression analysis showed the Hunt-Hess grade(OR =7.150,P =0.003),stent-assisted coil embolization(OR =15.777,P =0.010),and the serum Sema3E level(OR =1.756,P =0.027)were independent prognostic factors for intracranial aneurysms after interventional therapy.Conclusions The serum Sema3E level is closely correlated with the severity of intracranial aneurysms.The serum Sema3E level is a prognostic factor for interventional treatment,which can be used as a biomarker for predicting poor outcomes.

OBJECTIVE: To study the correlation of common cardiovascular risk factors with brain iron deposition. METHODS: Eighty-four elderly subjects without neurological diseases or brain trauma were included in the study. The cardiovascular risk factors were comprehensively assessed. MRI examination was performed to obtain high-resolution T1-weighted images and enhanced susceptibility weighted angiography (ESWAN) images, and R2^* figure was obtained by post-processing the ESWAN sequence. High definition T1 images were segmented using computer segmentation technique. After registration to the ESWAN image, R2^* values of each region of interest were extracted. Multiple linear regression analysis was used to analyze the relationship of R2^* values in each area of interest with gender, age and vascular risk factors. RESULTS Smoking was associated with increased R2^* values in the hippocampus, white matter and cortex (β=0.244, 0.317, 0.277, P<0.05 or P<0.01). Hypertension was correlated with the increase of R2^* in the putamen (β=0.241, P=0.027). Hyperglycemia was associated with the increase of R2^* in the thalamus (β=0.234, P<0.05). In the thalamus, the R2^* value of males was higher than that of females (β=0.320, P<0.05). Age was correlated with the R2^* values of thalamus, caudate nucleus, pallidus, white matter and cortex (β=-0.218、-0.254、0.216、-0.280 and -0.238, P<0.05 or P<0.01). CONCLUSIONS Common cardiovascular risk factors may lead to iron deposition in the brain, and the deposition patterns vary with the gender, age and different risk factors.

Objective: To analyze the ability of micro-implant nails placed in different locations in the posterior region to improve the hard and soft tissues of the labiodental region in patients with gummy smiles to provide a reference for clinicians. Methods: This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. Thirty young female patients with anterior tooth protrusions and gummy smiles were included in the retrospective study; 18 patients had micro-implant nails implanted between the premolars (group A), and 12 patients had implant nails placed between the roots of the premolar and the molar and an intraoperatively placed rocking-chair archwire (group B). The preoperative and postoperative distances from the incisal end of the upper mesial incisors to the lower point of the upper lip (U1-Stms), the vertical distance from the incisal end of the upper mesial incisors to the palatal plane (U1-PP), the vertical distance from the point of the alveolar ridge to the palatal plane (Spr-PP), the distance from the incisal end of the upper mesial incisors to the point of the alveolar margin (U1-Spr), and the vertical distance from the point of the proximal middle buccal cusp of the maxillary first molar to the palatal plane of the maxillary first molar (U6-PP) were measured in the cephalometric lateral radiographs of the two groups; additionally, the amount of hard and soft tissues of the upper anterior region exposedduring smiling and the maximum amount of gingiva exposed during smiling were assessed from the smile photograph. Results: After correction, the lip-dentition relationship improved significantly in both groups, with an average reduction of 2.6 mm in U1-Stms, 2.4 mm in U1-PP, 1.4 mm in Spr-PP, and 0.9 mm in U1-Spr in Group A. In group B, the U1-Stms was reduced by an average of 2.3 mm, the U1-PPs by an average of 1.6 mm, the Spr-PPs by 1.4 mm, and the U1-Spr by 0.2 mm. The difference between pre- and postoperative U6-PP in both groups was not significant (P>0.05). Group A had greater ∆U1-PP and ∆U1-Spr changes than group B(P<0.05). There was no difference between the two groups in terms of ∆U1-Stms or ∆Spr-PP (P>0.05). The amount of soft and hard tissue exposed and maximum amount of gingiva exposed in the upper anterior region of the smile were reduced in 30 patients postoperatively, with group A having anaverage reduction of 70.19% of the preoperative amount of soft and hard tissue exposed in the upper anterior region and an average reduction of 24.12% of the preoperative maximum amount of gingiva exposed, and group B having an average reduction of 76.12% of the preoperative amount of hard and soft tissue exposed in the upper anterior region and an average reduction of 31.88% of the preoperative maximum gingiva exposed after the operation. The difference in the ratio between the two groups was not statistically significant (P>0.05). Conclusion For patients with proptosis and gummy smiles, placing micro-implant nails between the roots of maxillary premolars can effectively lead to retraction and intrusion of anterior teeth to improve the lip-dentition relationship and improve gummy smile, and placing micro-implant nails between the roots of the maxillary second premolar and the first molar together with the use of rocking chair arches can also achieve a good therapeutic effect.
