Objective:To evaluate the recurrence and progression of patients with pT1 high grade urothelial carcinoma of bladder (UCB) and glandular differentiation.Methods:We retrospectively analyzed the clinical and pathological information of 208 patients diagnosed as pT1 high grade urothelial carcinoma in the Fifth Central Hospital of Tianjin from January 2006 to February 2019.Among them, 78 cases were diagnosed as glandular differentiation (UCGD), the other 130 patients without histologic variants were served as control. The UCGD group included 62 male and 16 female, whose median age was 67 years old (range 38-81 years old). The control group contained 105 male and 25 female, whose median age was 66 years old (range 40-82 years old). Kaplan-Meier and Cox proportional hazard regression analyses were used to evaluate the predictors of oncologic outcomes.Results:The disease recurrence rate and progression rate in UCGD group were 65.4% (51/78) and 28.2% (22/78), higher than 38.5%(50/130) and 14.6%(19/130) of control group ( P<0.05). The median recurrence time in UCGD group was 41 months while 55 months in the control group. The median progression time in UCGD group was 39 months while 54 months in the control group. According to the univariate analysis, largest tumor size ( P=0.030), UCGD ( P=0.003) and lymphovascular invasion (LVI) ( P=0.032) were associated with disease recurrence. UCGD ( P=0.036) and LVI ( P=0.011) were associated with progression. Additionally, Cox multivariate analysis revealed that UCGD ( P=0.001), LVI ( P=0.038) were the independent factors of disease recurrence. UCGD ( P=0.007) and LVI ( P=0.037) were also found to be the independent factors of disease progression. Conclusions:Patients with T1 stage UCB and UCGD are at higher risk of disease recurrence and progression. Therefore, these patients should be followed up closely after being diagnosed and undergo individual treatment according to the situation.

Objective: To synthesize a folic acid (FA)-modified pH-sensitive nanomicelle containing sorafenib (SF) and superparamagnetic iron oxide (SPIO), and to access its visibility in MRI and anti-cancer efficacy on hepatocellular carcinoma (HCC) in vitro. Methods: The copolymer FA-PEG-Pasp (DBA/DIP) of FA, poly(ethylene glycol), N,N-dibutylethylenediamine and N,N-diisopropylethylenediamine grafted poly (L-aspartic acid) were prepared. SF and SPIO were encapsulated inside the copolymer to synthesize the targeting micelle FA-PEG-PAsp (DBA/DIP)-SPIO/SF (FPASS). The folate-free micelle[PEG-PAsp (DBA/DIP)-SPIO/SF (PASS)] was used as nontargeting micelle. The physicochemical properties and drug release behavior of the micelles were analyzed. MRI of HepG2 cells incubated with FPASS and PASS with different Fe concentrations and Prussian blue staining of cells treated with the micelles (Fe concentration of 20 μg/ml) was performed to assess the drug delivery capability and imaging function of the micelles. For the FA competitive inhibition assay in these experiments, HepG2 cells were pre-treated with an excess amount of free FA prior to the incubation with FPASS. Cell viability, cell apoptosis, cell cycle and tube formation assays were conducted for evaluating the anti-HCC effects of the micelles. Comparison between groups was analyzed by one-way ANOVA, and multiple comparisons correction was performed by LSD test. Results: The diameters of FPASS and PASS were (102.3±5.2) nm and (107.1±5.7) nm, respectively; the δ potentials of them were (29.7±1.6) mV and (31.5±1.4) mV, respectively. The T₂ relaxivity of both the micelles was (5.2±0.4) ml·μg^-1·s^-1, which was much higher than that of water soluble Fe₃O₄ nanoparticles [(2.3±0.1) ml·μg^-1·s^-1; F=76.45, P<0.01]. SF released from the micelles was much faster at pH5.0 than at pH7.4, which indicated that the micelles had a pH-triggered drug release behavior. MRI of HepG2 cell samples revealed the signal intensity on T₂WI images and the T₂ value on T₂-map images decreased with the increasing Fe concentrations in the micelles. At the same Fe concentration (5, 10, 20 and 40 μg/ml), the cells of FPASS group exhibited a more significant decrease in T₂ signal intensity and T₂ value compared with those of PASS group or FA competitive inhibition group (F=8.69, 14.03, 27.27, 32.25 and 19.80, 45.76, 113.20, 66.80; P<0.01). Prussian blue staining verified the existing of SPIO in the cytoplasm of cells. Compared with PASS, FPASS presented significantly higher anticancer effects on inducing apoptosis, causing G0/G1 phase arrest on HepG2 cells and inhibiting tube formation on human umbilical vein endothelial cells (t=7.905, 4.399 and 3.454, respectively; P<0.01). Conclusions The pH-sensitive nanomicelle FPASS was successfully constructed. This micelle possessed a hypersensitive MRI-visible function and a targeting SF delivery capability which may contribute to a significant anti-HCC effect.

? Objective? To explore the application of tsusanli warming moxibustion in early rehabilitation in patients with cerebral infarction. Methods? Totally 120 patients with cerebral infarction and stable vital signs treated in the Department of Neurology of the First People's Hospital of Huzhou from January 2018 to March 2019 were selected using convenient sampling and divided into control (n=60) and observation (n=60) groups according to the random number table. Patients in the control group received routine drug therapy and rehabilitation care, while patients in the observation group received warming moxibustion, routine drug therapy and rehabilitation care. Bathel Index (BI), National Institute of Health Stroke Scale (NIHSS) and myodynamia were used to compare the effects of intervention. Results? The total effective rate in the observation group was 91.3%, higher than 66.7% in the control group, and there was statistically significant difference between the two groups (P＜0.05). The number of patients with a BI ≥ 75 in the observation group were more than that in the control group 2 and 3 months after treatment, and there was statistically significant difference between the two groups (P＜0.05). The NIHSS score of the observation group was lower than that of the control group 2 and 3 months after treatment, and there was statistically significant difference between the two groups (P＜0.05). Conclusions? Tsusanli warming moxibustion combined with integrated Chinese and Western medical methods in routine rehabilitation care show an obvious effect on the neurological function in patients with cerebral stroke during early rehabilitation, which can also improve their activities of daily living.

Aim ToinvestigatetheeffectsofCa2+/calmodulin-dependent protein kinase Ⅱ inhibitor KN-93 on calcium overload-induced heart injury.Methods Thirty-twoisolatedratheartswererandomlydivided into the control group,KN-93 control group,calcium paradox group,and calcium paradox with KN-93 treat-ment group.Left ventricular pressure were recorded, and the heart function was evaluated by the left ventric-ular end-diastolic pressure (LVEDP ) and developed pressure (LVDP).Coronary flow (CF)were collect-ed,and lactate dehydrogenase (LDH)content was de-termined.Triphenyltetrazolium chloride staining was usedtomeasuretheinfarctsize.Results Compared with the control group,KN-93 at 2. 5 μmol·L-1 had no effects on coronary flow,cardiac performance and cell death at the end of perfusion in normal rats (P>0. 05 );The hearts of calcium paradox exhibited a de-crease in LVDP and CF,meanwhile an increase in LV-EDP,LDH,and infarct size of 18 ±7. 2% (P <0. 01).2. 5 μmol·L-1 KN-93 further increased the levels of LVEDP,LDH and infarct size (P<0. 01)in Ca2+paradoxical hearts,while it provoked the decline intheCFandLVDP(P<0.01).Conclusion The data demonstrates that KN-93 aggravates heart injury in calcium paradox,it also suggests that CaMKⅡ is in-volved in the Ca2+overload-induced heart injury.

Objective To investigate risk factors of the prognosis of patients with severe fever with thrombocytopenia syndrome (SFTS).Methods From May 2012 to July 2014,17 cases of severe fever with thrombocytopenia syndrome in Renmin Hospital of Wuhan University were treated.Clinical data including history of epidemiology,clinical manifestations,complications,physical examination and laboratory test results on admission and the third day after admission were retrospectively analyzed and compared with the death group and recovery group by application of Spearman correlation analysis.Results Elderly male patients with neuropsychiatric symptoms,or abnormal liver function,or abnormal blood clotting function had higher risk of the poor prognosis.In SFTS patients,AST,ALT was significantly increased,AST 539 U/L (229.73,545.4) U/L (r =0.597,P =0.015) was a risk factor affecting prognosis.Elevated blood ammonia indicated serious liver dysfunction and neurological dysfunction which were manifested as irritability,delirium,and trembling limbs.In SFTS patients,platelets were significantly decreased accompanied with mouth ulcers / bleeding gums,gastrointestinal bleeding.PLT 24.88 × 10 9/L-1 (12.75,35.00) ×10 9/L-1 (r=0.557,P=0.005) or APTT 86.06 s (66.88,114.18) (r=0.798,P=0.001) or D-dimmer 9.79 mg / L (4.09,16.51) mg/L (r =0.597,P =0.015) are risk factors affecting poor prognosis.Conclusions On the third days after admission,AST,WBC,PLT,APTT,Ddimmer are risk factors for prognosis of patients with severe fever with thrombocytopenia syndrome infected by a novel bunyavirus.

SUMMARY An involved internal iliac artery is usually embolized when performing endovascular aneu -rysm repair for aortoiliac or isolated iliac artery aneurysm .This can lead to complications such as buttock claudication ,colon ischaemia and erectile dysfunction .Iliac branch device ( IBD ) is an endograft de-signed specifically for iliac bifurcation to preserve internal iliac flow .It was performed with high technical success rates and encouraging mid-term patency .Here we report a case of right iliac aneurysm developed 3 years after endovascular aneurysm repair for an aortoiliac aneurysm , with the patient ’ s left internal ar-tery been sacrificed then .Using a handmade IBD , we excluded the aneurysm without occlusion of the ip-silateral internal iliac artery or any type of endoleak .Both the design and deployment of this IBD are dis-tinctive that we would like to share our experience with all the colleagues .

Objective To investigate the clinical features of spontaneous isolated superior mesenteric artery dissection (SISMAD), and to discuss its interventional therapy. Methods The clinical data of 10 patients with SISMAD, who were admitted to authors' hospital to receive interventional treatment during the period from January 2006 to June 2014, were retrospectively analyzed. All the 10 patients were males, aged 44-66 years with a mean of (53±8) years. Clinically, all patients presented with acute-onset abdominal pain or pain around umbilicus, as the effect of conservative treatment was poor, implantation of self-expandable bare stent was carried out. Results Successful implantation of self-expandable bare stent was accomplished in all 10 patients;only one stent was used in 7 patients and 2 stents were used in 3 patients. The blood in the true lumen of superior mesenteric artery (SMA) restored and the residual stenosis extent was less than 15%. The technical success rate was 100%. The abdominal pain was relieved in 8 patients on the operative day after treatment, and in 2 patients the abdominal pain was relieved in 2 days after treatment. All the patients were followed up for 7-71 months (mean of 36 months) and the follow-up rate was 100%. After the treatment patients had no symptoms of abdominal discomfort. Contrast-enhanced CT scan performed at 6, 12 and 24 months after the treatment showed that SMA and stent was patent and no aneurysmal dilatation was observed. Conclusion For the treatment of SISMAD endovascular implantation of self-expandable bare stent is clinically safe and feasible, and its long-term effect is satisfactory.

Objective To evaluate the feasibility of endovascular repair for retrograde type A aortic dissection.Method 35 patients of retrograde type A aortic dissection admitted to Peking University People's Hospital from December 2001 to March 2014 were treated with endovascular repair.There were 33 males and 2 females with mean age of 46 ± 9 years.29 were on acute stage,2 on subacute stage and 4 on chronic stage.The entry tear was in the descending thoracic aorta in 32 cases,between the left subclavian artery and the left common carotid artery in one,and between the left common carotid artery and the innominate artery in two.Results Entry closure was achieved in all patients with a covered stent.2 patients died in 30 days postoperatively (5.7％).1 patient with two chimney developed acute renal artery embolized which was infused by false lumin (2.9％).One patient developed transient paraparesis after graft deployment(2.9％).During the follow-up period,the aortic remodeling is perfect,no entry tear was noted in the ascending thoracic aorta.All the endografts for preserving supra-aortic branches were patent.Conclusions The endovascular repair for retrograde type A aortic dissection is feasible and effective.
