ABSTRACT

The incidence of inflammatory myofibroblastic sarcoma is low, and bladder origin is more rare. We reported a 58-year-old patient with painless gross hematuria for one week. Total abdominal CT examination showed soft tissue mass in the anterior wall of the bladder, which was considered as bladder cancer, and bladder tumor resection was performed. Postoperative pathology showed inflammatory myofibroblastic sarcoma. Therefore, radical cystectomy was performed because of the high degree of malignancy. There was no recurrence during 3 years follow-up.

ABSTRACT

Objective:To evaluate the clinical efficacy of PTCD and ERCP combined with T tube in the perioperative period of biliary anastomosis in patients with moderate to severe obstructive jaundice.Methods:The data of 93 patients with moderate obstructive jaundice who met the inclusion criteria and planned to undergo cholangiojejunostomy (including reconstruction after pancreaticoduodenectomy) in Shuguang Hospital Affiliated to Shanghai University of traditional Chinese medicine from March 2015 to December 2021 were collected. According to the perioperative drainage strategy, 54 cases were divided into PTCD group and 39 cases were divided into ERCP combined with intraoperative T-tube drainage group. Retrospective cohort method was used to analyze the bile duct diameter, postoperative hospital stay, operation cost, time of jaundice reduction, degree of jaundice reduction, average postoperative bile loss, postoperative bile leakage, abdominal infection of the two groups. The measurement data were expressed as mean ± standard deviation( ± s), and t test was used for comparison between groups. The data of skewed distribution were represented by M( Q1, Q3), and nonparametric rank sum test was used. Chi-square test was used for counting data. Results:The preoperative yellowing reduction time, operation cost, mean bile loss 7 days after operation, time to remove biliary drainage tube, and postoperative hospital stay in PTCD group were (5.9±3.1) d, (59 846.3±9 129.7) yuan, 210.0(170.0, 325.0) mL/d, (18.4±5.6) d, and(10.7±4.4) d, respectively, while those in ERCP group were (9.5±4.4) d, (77 833.1±12 164.5) yuan, 285.0(225.0, 370.0) mL/d, (41.4±17.2) d and(15.3±5.6) d, respectively. The difference between the two groups was statistically significant ( P<0.05). There was no significant difference between the two groups in general condition before drainage, cholangitis and hemorrhage after drainage, degree of jaundice reduction, bile leakage after surgery, abdominal infection, etc. Conclusions:When performing biliary enterostomy in patients with moderate or above obstructive jaundice, PTCD and ERCP combined with intraoperative T-tube drainage are effective means to improve the safety of perioperative period. PTCD has some advantages in reducing jaundice efficiency, operation cost and rapid postoperative rehabilitation.

ABSTRACT

Objective:To investigate the feasibility and clinical value of MRI quantitative evaluation technique in detecting sternocleidomastoid muscle fibrosis in patients with nasopharyngeal carcinoma (NPC) after radiotherapy.Methods:From August 2019 to March 2021, 45 patients with clinically confirmed NPC after radiotherapy and 30 healthy controls who underwent physical examination in Lishui Hospital of Zhejiang University were enrolled in our study. According to the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer (RTOG/EORTC) classification criteria of late radiation reactions respectively, the sternocleidomastoid muscle injury in the NPC group was divided into grade Ⅰ, Ⅱ and Ⅲ, which included 8, 32 and 5 patients respectively. All patients underwent T 1 mapping and T 2 mapping imaging of the neck. Firstly, the mapping images of sternocleidomastoid muscle between the two groups were analyzed and compared. Using NUMARIS/4 software of Siemens image post-processing workstation, the region of interest was manually drawn along the edge of sternocleidomastoid muscle at the level of laryngeal chamber in axial mapping diagram. Then, T 1 and T 2 values and the long and short diameters of sternocleidomastoid muscle were measured respectively. Finally, the differences of the parameters between the two groups were compared by independent sample t-test, Spearman rank correlation was used to analyze the relationship between the average T 1 and T 2 values of bilateral sternocleidomastoid muscles and the grade of late radiation injury. Results:Compared with the control group, the shape of sternocleidomastoid muscle in the NPC group was smaller in shape, with irregular edge and uneven increase of T 1 mapping color scale. There was no significant difference in muscle signal in T 2 mapping. The T 1 values of left and right sternocleidomastoid muscles in the NPC group were (1 524.7±97.6) and (1 496.5±93.2) ms respectively, which were significantly higher than those in the normal control group [(1 231.5±85.3) and (1 275.9±90.9) ms] ( P<0.05), and the T 2 values of left and right sternocleidomastoid muscles in the NPC group were (28.4±4.8) and (28.4±3.6) ms respectively, which were lower than those in the normal control group [(30.4±3.5) and (30.4±3.5) ms] ( P<0.05). The long and short diameters of bilateral sternocleidomastoid muscles in the NPC group were shorter than those in the control group ( P<0.05). The average T 1 and T 2 values of bilateral sternocleidomastoid muscles in NPC patients after radiotherapy were (1 510.6±95.4) and (28.4±4.2) ms respectively, The T 1 value was positively correlated with the classification of advanced radiation injury ( r=0.78, P<0.001), and T 2 value was negatively correlated with the level of advanced radiation injury ( r=-0.87, P<0.001). Conclusion:Mapping quantitative evaluation technique can noninvasively and objectively detect and evaluate sternocleidomastoid muscle fibrosis after NPC radiotherapy, which has potential clinical application value.

ABSTRACT

Objective@#To explore the relationship of sleep with C reactive protein (CRP) abnormality and hyperinsulinemia in adolescents, and to provide reference for early prevention of metabolic disorders.@*Methods@#Based on the Chinese Metabolic Syndrome Cohort Study in Anhui Province, a total of 653 adolescents aged 12 to 19 were selected to examine the relationship between wakeup time, bedtime, sleep disordered breathing (SDB) and CRP abnormality as well as hyperinsulinemia.@*Results@#Later wakeup time (OR=1.68, 95%CI=1.03-2.75) was positively correlated with a higher risk of fasting hyperinsulinemia. Late bedtime (OR=1.96, 95%CI=1.29-2.99) was associated with 2 h postprandial hyperinsulinemia. Among those with high CRP concentration, late wakeup time and late bedtime were positely associated with hyperinsulinemia than those with normal CRP concentration; and the correlation between SDB and hyperinsulinemia was observed.@*Conclusion@#Later wakeup and late bedtime may be risk factors for hyperinsulinemia in adolescents. High concentrations of CRP may further increase the risk of hyperinsulinemia, a condition associated with sleep problems.Teenagers should get up and go to bed as early as possible.

ABSTRACT

Radical cystectomy is widely used as a gold standard in the treatment of invasive bladder cancer. Urinary diversion is required after radical cystectomy. In all kinds of urinary diversion procedures, orthotopic neobladder is preferred by its advantages such as spontaneous voiding, avoidance of external ostomy and improvement of body image. After surgery, urinary incontinence is a common complication. In this review, we systematically outline the management of urinary incontinence in men after radical cystectomy and orthotopic neobladder. And we mainly describe the influential factors of urinary incontinence, such as preoperative diabetes, intraoperative intestinal selection and nerve preservation, and postoperative urinary tract infection. The related post-operative management of urinary incontinence that has been conducted previously is also described in detail. The aim of this study is to provide guidance for the systematic treatment of urinary incontinence in clinical practice, and to look forward to the possible future development directions of urinary incontinence treatment, such as bladder neck reconstruction and stem cell therapy.

ABSTRACT

Objective:Since December 2019, novel coronavirus infection has occurred in Hubei province and spread throughout the country quickly. This new crown viral pneumonia was named as coronavirus disease of 2019 (COVID-19) by WHO. However, at present, there is a high incidence of acute aortic dissection in winter and spring. How to prevent the spread of the epidemic and choose the appropriate treatment is an important topic for the patients with acute aortic dissection.Methods:From January 16, 2020 to February 26, 2020, a total of 37 of acute aortic dissection operations were carried out in several cardiovascular surgery centers in Hubei Province. There were 18 cases of Stanford type A aortic dissection and 19 cases of Stanford type B aortic dissection. There were 10 cases (55.55%) with ascending aorta replacement and 7 cases (38.89%) with Bentall procedure for aortic root surgery, and total arch replacement with stented elephant trunk implantation were performed in 14 cases (77.8%). In 19 patients with Stanford type B aortic dissection, thoracic endovascular aortic repair was performed, with the left subclavian artery chimney technique in 2 cases.Results:No deaths occurred within 30 days of hospitalization. Preoperative nucleic acid testing excluded 7 cases of novel coronavirus infection, and 3 suspected cases underwent emergency surgery. the three-level protective standard was adopted in the majority of the surgeries(62.2%, 23/37), and 11 patients were negative in the reexamination of viral nucleic acid after the operation.Conclusion:During the epidemic period, patients with acute aortic dissection should be carefully identified with actife COVID-19 before surgery. The treatment principles-" prevention and control of pneumonia epidemic should be emphasized, conservative medical management should be taken in the comfirmed cases, the selective operation should be delayed as far as possible, and the operation should be reasonable performed in critical cases" should be followed, which can save patients' lives to the greatest extent and prevent the spread of the virus.

ABSTRACT

Prostate cancer is the most common malignant tumor in male reproductive system. In China, the incidence of prostate cancer is increasing rapidly due to an aging population, changes in people's lifestyles, and the gradual promotion of serum prostate-specific antigen (PSA) screening. At present, ultrasound-guided prostate biopsy is the standard for diagnosis of PCa. However, it is still a hot topic to determine the spatial distribution of tumor in the prostate so as to better evaluate the patients, improve the detection rate of prostate cancer and better guide the follow-up diagnosis and treatment measures to reduce the cancer-related mortality. Here, the current review will discuss the characteristics of spatial distribution of PCa.

ABSTRACT

Objective To measure the oxygen partial pressure (PtO2) within a situation of vacuum sealing drainage (VSD) implement, and to discuss the potential mechanism of VSD alleviating skeletal muscle ischemia reperfusion (I/R) injury in rabbits. Methods Rabbits were randomly(random number) divided into three groups: sham (n=10), I/R (n=10) and I/R+VSD (n=10) groups. In the I/R group, left hind limb ischemia was induced by clamping the femoral artery and vein for 4 h, then released for 6 h, to allow reperfusion of the limb. VSD was only performed in the I/R+VSD group during the reperfusion period. All rabbits were administered a series test of PtO2 in different time points before and after reperfusion, and the left hind limb skeletal muscle and ear vein blood samples were immediately harvested for biochemical analyses, including hypoxia inducible factor 1 alpha (HIF-1α) mRNA and protein, and lactic acid (LA). One-way analysis of variance (ANOVA), Fisher's least significant difference (LSD) test or Tamhane's T2 test was used where appropriate to analyze the experimental results. Results The levels of PtO2 in the I/R and I/R+VSD groups were decreased after ischemia, but no significant difference was noted between the two groups (t=1.322, P=0.296). The PtO2 levels in the I/R+VSD group were less increased than those in the I/R group after reperfusion (t=2.015, P=0.046). The levels of HIF-1α mRNA and protein were increased after I/R injuries (F=10.120, P=0.002; F=36.480, P<0.01; F=6.960, P=0.015, F=4.470, P=0.035), and the levels in the I/R+VSD group were greater than those in the I/R group (t=1.799, P=0.048, t=5.911, P=0.019; t=1.878, P=0.046, t=2.609, P=0.030). The LA levels were significantly increased in the skeletal muscle and blood samples in the I/R and I/R+NPWT groups compared with those in the sham group at the final stage (F=9.540, P=0.002 and F=13.750, P<0.01), but the levels in the I/R+VSD group were less than those in the I/R group (t=2.263, P=0.040 and t=3.617, P=0.027). Conclusions Our results suggested that VSD technique decreased PtO2 in regional ischemic muscles and led to increases in HIF-1α mRNA and protein that subsequent accumulation of less LA in both of regional skeletal muscle and systemic blood circulation, which provided protection effect after I/R injury in rabbits.

ABSTRACT

Objective@#To investigate the preoperative clinical criteria for nerve-sparing radical prostatectomy.@*Methods@#A retrospective analysis of 79 patients undergoing radical prostatectomy with complete clinical and pathological data in Jinhua Hospital of Zhejiang University from January 2012 to December 2016 was performed. The distance between the edge of the prostate tumor and the neurovascular bundle (NVB) was measured. When the distance between the edge of the tumor and the ipsilateral NVB was >2 mm, NVB retention surgery can be performed; when it was ≤2 mm, NVB retention surgery cannot be performed. The influencing factors of the distance between the tumor edge and NVB were analyzed by χ 2 test and logistic regression analysis.@*Results@#Univariate analysis showed that side-specific positive biopsy core ≥1/3, side-specific maximum tumor length in biopsy core ≥5 mm, side-specific tumor involvement rate in biopsy core ≥1/2 and extraprostatic cancer extension by preoperative magnetic resonance imaging (MRI) examination were associated with the distance between the tumor edge and NVB (all P < 0.01). Multivariate analysis showed that extraprostatic cancer extension by preoperative MRI examination (OR = 3.66, P = 0.006) and side-specific positive biopsy core ≥1/3 (OR = 3.39, P = 0.008) were the independent influence factors.@*Conclusion@#The clinical criteria for a nerve-sparing radical prostatectomy are side-specific positive biopsy core <1/3 and no extraprostatic extension by preoperative MRI examination.

ABSTRACT

Objective To explore the application and early efficacy of modified Veil nerve-sparing technique during laparoscopic radical prostatectomy(LRP).Methods Fifty-seven modified Veil nerve-sparing during LRP procedures were performed in patients with clinically localized prostate cancer between 2012 and 2016 by the same surgeon.Preoperative PSA level was 10.9 μg/ml,and Gleason score was 6.06(5-8).TNM clinical stage showed cT1 in 39 cases and cT2in 18 cases.All patients underwent transrectal ultrasonography before operation. Prostate volume was 40.2 (26- 99) ml. ECT bone scan excluded bone metastasis.MRI or CT examination showed no obvious prostate invasion and lymph node metastasis. The key technology was anatomical separation of detrusor apron, dorsal vascular complex (DVC) and the level between the prostate capsule, and a complete reservation was accomplished. Measurements: the rates and location of positive surgical margins (PSM) and tumor biochemical recurrence rate as well as functional outcomes were presented.Questionnaires were used to assess urine function and IIEF-5 score was used to estimate sexual function.Results Fifty-seven cases were followed up,and the average follow-up of 27.3(6-65)months.Five cases showed biochemical recurrence after 23 months.Five patients had a PSM(2 patients in apical margins,1 patient in left side,1 patient in right side and 1 patient in the bottom).At catheter removal,49 of 57 patients(86%)were dry(0 pads),and 8 of 57 patients(14%)needed one security pad.After 3 months and 6 months,42%(24 of 57 patients)and 60%(34 of 57 patients)presented an International Index of Erectile Function score>15(with or without phospho-diesterasetype-5inhibitors). Conclusions The modified Veil nerve-sparing technique during LRP can retain the fascia around the prostate more completely and restore postoperative urine and erectile function early.For selective cases, it will not increase the positive rate of surgical margins and biochemical recurrence rate.

ABSTRACT

Parkinson's disease(PD) is a common neurodegenerative disease afflicting many older individuals.To date,mutations in the GBA gene is considered as a major risk factor for PD,but the underlying mechanism is still unclear.Glucocerebrosidase (GCase) encoded by GBA may work as a biomarker for the early diagnosis of PD associated with GBA mutations (PD-GBA).Increasing GCase enzyme activity or reducing its substrate availability may protect the neuron and slow the progression of PD-GBA.

ABSTRACT

Objective: To investigate the effects of microRNA-107 (miR-107) on the proliferation and in vitro vasculogenic mimicry of Ewing sarcoma cells, and to explore the possible mechanism. Methods: The expression level of miR-107 in several Ewing sarcoma cell lines was detected by real-time fluorescent quantitative PCR. The synthesized miR-107 mimic and the scramble mimic (as the control) were transfected into Ewing sarcoma RD-ES and SK-ES-1 cells, respectively. The recovery of miR-107 expression in RD-ES and SK-ES-1 cells after transfection was verified by real-time fluorescent quantitative PCR. The effects of miR-107 overexpression on the proliferation and vascular mimicry formation of RD-ES and SK-ES-1 cells were detected by CCK-8 assay and matrigel vasculogenic mimicry assay, respectively. The expressions of hypoxia inducible factor-1ß (HIF-1ß) mRNA and protein in RD-ES and SK-ES-1 cells after transfection with miR-107 mimic were detected by real-time fluorescent quantitative PCR and Western blotting. Results: Comparing with human mesenchymal stem cells, miR-107 was low expressed in Ewing sarcoma RD-ES and SK-ES-1 cells (both P < 0.01). After transfection with miR-107 mimic, the expression of miR-107 was significantly up-regulated in RD-ES and SK-ES-1 cells (both P < 0.01). The proliferation and vascular mimicry formation of RD-ES and SK-ES-1 cells were significantly inhibited after transfection with miR-107 mimic (all P < 0.05). Furthermore, miR-107 overexpression significantly suppressed the expressions of HIF-1ß mRNA and protein in RD-ES and SK-ES-1 cells (all P < 0.01). Conclusion: miR-107 was low-expressed in Ewing sarcoma RD-ES and SK-ES-1 cells. The overexpression of miR-107 can inhibit the proliferation and vascularization of Ewing sarcoma cells, which may be related to the targeting regulation of HIF-1ß expression.

ABSTRACT

<p><b>OBJECTIVE</b>To assess the effect of small interfering RNA (siRNA)-mediated suppression of CDK6 expression on the proliferation and cell cycles of nasopharyngeal carcinoma (NPC) cells in vitro.</p><p><b>METHODS</b>QRT-PCR was used to examine the differential expression of CDK6 in 30 NPC tissues and 18 normal nasopharyngeal tissues. A siRNA targeting CDK6 was transfected in NPC CNE2 cells, and MTT assay and flow cytometry were used to analyze the changes in cell proliferation and cell cycle distribution. Western blotting was used to examine the expressions of the cell cycle-related factors.</p><p><b>RESULTS</b>Compared with normal nasopharyngeal tissues, NPC tissues showed an increased expression of CDK6 mRNA. Knocking down CDK6 expression obviously inhibited tumor cell growth and cell cycle transition from G1 to S phase and caused reduced expressions of CDK4, CCND1, and E2F1 and enhanced expression of the tumor suppressor p21.</p><p><b>CONCLUSION</b>NPC tissues overexpress CDK6. Knocking down CDK6 expression inhibits the growth and cell cycle transition of NPC cells in vitro by inhibiting the expressions of CDK4, CCND1, and E2F1 and upregulating tumor suppressor p21 expression.</p>

ABSTRACT

Objective To investigate the changes of serum bilirubin level in elderly patients with acute cerebral infarction and its significance.Methods 164 hospitalized elderly patients,who suffered from acute cerebral infarction within 1 week after onset,were divided into 2 groups according to age:group A aged over 60 years(n=85) and group B aged 40-60 years(n=79),and 66 healthy subjects aged over 40 years were collected as controls(group C).Serum bilirubin levels in all subjects were determined.The ratio of pulse pressure over mean arterial pressure(PP/MAP) in group A and B was calculated.Nerve function scores in the three groups were detected before and after 2 weeks of treatment.Meanwhile,the data of risk factors including blood glucose,blood pressure,blood lipids,smoking and drinking in group A and B were collected.Results Compared with group C,serum total,direct,indirect bilirubin levels were increased in group A and B(both P<0.01),and the change was smaller in group A than in group B(P<0.05).The nerve function scores was lower in group A than in group B before and after treatment [(35.2±12.6) vs.(44.3±7.9),(40.7±9.1) vs.(51.3± 4.1),t=5.58,9.73,both P<0.01],but PP/MAP and the numbers of risk factors were higher in group A than in group B [(0.46±0.06) vs.(0.38±0.06),93.01 vs.71.20,both P<0.01].There were no significant correlations of serum total,direct and indirect bilirubin levels with nerve function scores in group A or B(all P>0.05).Conclusions Serum bilirubin level is increased in patients with acute cerebral infarction,but the endogenous antioxidant capacity is decreased because of aging,multiple risk factors and more serious atherosclerosis in elderly patients,and the increment of bilirubin level is relatively smaller in acute cerebral ischemia,leading to the reduced protective effect against stress.Serum bilirubin level may influence the prognosis in patients with acute cerebral infarction.

ABSTRACT

Objective To observe the expression of acid-sensing ion channel la (ASICla) and to investigate the effect of intracellular Ca2 + concentration on focal cerebral ischemia in diabetic rats.Methods 108 male Wistar rats were divided into three groups:group A [rats with middle cerebral artery occlusion (MCAO)],group B [rats with MCAO and diabetes (DM + MCAO)],group C [rats with MCAO and diabetes treated with fasudil intervention (DM+ MCAO+ fasudil)] (n=36 each).Samples were obtained at the time points of 1,3,6 and 24 h after ischemia respectively (n=9).Models of MCAO and DM+MCAO were prepared.Rats in DM+MCAO+Fasudil group were treated with fasudil 1 mg/Kg by caudal vein injection after half an hour when DM+MCAO model successfully prepared.ASICla expressions were detected at different time points of ischemia in the 3 groups respectively.Ca2+ concentration in ischemia cortex cells were determined at different time points of ischemia in group B and C.Results ASICla expressions were gradually increased along with the ischemia time in group A and B (group A:0.71±0.10,0.80±0.11,0.86±0.08,0.93±0.09;groupB:0.86±0.11,1.05±0.51,2.42±0.08,2.78±0.04; all P< 0.05),and ASICla expressions at different time points were higher in group B than in group A (all P< 0.05).Ca2-concentration were gradually increased along with the ischemia time in group B (106.32± 18.6,137.84±14.32,151.94± 18.38,183.61±7.96,all P<0.05).Compared with group B,the levels of ASICla expression and calcium current were reduced in group C.Conclusions The activation of ASICla increases calcium ion flow internal pathway leading to intracellular calcium overload,which may be one of the reasons for the aggravation of focal cerebral ischemia in diabetes.
