ABSTRACT

Neurosyphilis is one of the most serious clinical manifestations of syphilis. In recent years, more and more neurosyphilis cases have been reported in Chinese literature. However, the exact incidence of neurosyphilis is unknown, and there are still some key scientific problems urgent to be solved in clinical diagnosis and treatment, pathogenesis, and prevention and control of neurosyphilis. Therefore, in order to provide a reference for the prevention and treatment of neurosyphilis, this article proposes the CARE-NS strategy, including the following 6 aspects: Comprehensive management including multiple disciplinary treatment (C) , Alleviating neurological impairment and sequelae (A) , Risk factors and clinical epidemiology (R) , Etiology and pathogenesis (E) , New diagnostic indicators and strategies (N) , Social impact and cost-effectiveness analysis (S) .

ABSTRACT

Objective:To investigate the phagocytosis of Treponema pallidum (Tp) by macrophages and the polarization direction of macrophages after Tp stimulation. Methods:Human THP-1 monocyte-derived M0 macrophages were stimulated with the Tp Nichols strain, and the phagocytosis of Tp by macrophages and changes in the intracellular structure of macrophages were observed by transmission electron microscopy and immunofluorescence staining. After 12-hour stimulation by Tp, Tp was removed, the M0 macrophages continued to be cultured for 24, 48, 72 hours and 6 days. Western blot analysis and immunofluorescence staining were performed to determine the expression of the M1 macrophage marker CD86 and M2 macrophage marker CD163, and enzyme-linked immunosorbent assay was conducted to detect levels of M1-type cytokines interleukin (IL) -12 p70, interferon (IFN) -γ, chemokine ligand 10 (CXCL10) , IL-6, tumor necrosis factor (TNF) -α and IL-1β, as well as the M2-type cytokine transforming growth factor (TGF) -β1 in the culture supernatant of macrophages. Dunnett- t test was used for multiple comparisons. Results:As transmission electron microscopy showed, after the stimulation by Tp, the macrophages extended pseudopodia and engulfed Tp, leading to swelling and obviously irregular hyperplasia of endoplasmic reticulum as well as enlargement of mitochondria. Moreover, after additional culture for 24, 48, 72 hours and 6 days, CD86 was highly expressed, but CD163 was lowly expressed in the Tp-treated macrophages; at 24 hours, the supernatant levels of IL-12 p70, IFN-γ, CXCL10, IL-6, TNF-α and IL-1β were significantly higher in the Tp-treated group than in the control group (all P<0.001) , but there was no significant difference in the TGF-β1 supernatant level between the 2 groups ( P>0.05) . Conclusions:After engulfment of Tp, the structures of endoplasmic reticulum and mitochondria in THP-1-derived macrophages markedly changed. Tp could induce the polarization of M0 macrophages into M1 macrophages, and phenotypic switch from M1 to M2 macrophage polarization was not observed within 6 days after Tp stimulation.

ABSTRACT

Objective:To analyze the urodynamic and clinical features of detrusor underactivity(DU)in elderly men aged 60 years and over.Methods:Five hundred and seventy-three men aged 60 years and over underwent urodynamic measurements due to dysuria were retrospectively analyzed.According to the urodynamic parameters of bladder contractibility index(BCI)and bladder outlet obstruction index(BOOI), they were divided into the three groups: only detrusor underactivity(DU group)(BCI<100 and BOOI<20), only bladder outlet obstruction(BOO group)(BCI≥100 and BOOI≥40), and the combined non-DU and non-BOO group(NDB group)(BCI≥100 and BOOI<20). The urodynamic and clinical features were compared between the three groups.Results:The internalized 323 patients meeting inclusion and exclusion criteria were divided into 3 groups: 75 in the DU, 207 in the BOO and 41 in the NDB.The age was higher in DU and BOO groups than in NDB group( P<0.05). The DU group versus the NDB group showed the higher levels or values in the volume at first desire(FDV)[(279±80)ml vs.(238±72)ml], the proportions of incomplete bladder emptying(41% vs.17%), urine flow interruption(39% vs.15%)and retention(26% vs.7%), and the lower levels in the voiding efficiency(VE)[(61±32)% vs.(110±41)%], (all P<0.05). The DU group vs.the BOO group showed the increased levels or values in the FDV[(279±80)ml vs.(206±67)ml]and maximum cytometric capacity(MCC)(353±113 ml vs.281±94 ml)and the proportions of urine flow interruption(39% vs.22%), TURP(26% vs.6%), and retention(26% vs.14%), and the decreased levels or values in the VE[(61±32)% vs.(78±37%)], the proportions of DO(41% vs.77%), urgency(26% vs.43%)and nocturia(23% vs.39%)(all P<0.05). Conclusions:The main urodynamic and clinical features are manifested as the reduction of bladder sensation and bladder emptying rate, urine flow interruption, urinary retention and having a TURP history in elderly man with detrusor underactivity.The proportions of DU and BOO are increased along with aging.

ABSTRACT

Objective To investigate the relationship between sleep beliefs and attitudes and sleep quality in patients with stable coronary heart disease. Methods Totally 390 patients with stable coronary heart disease were investigated by the Pittsburgh Sleep Quality Index (PSQI), Dysfunctional Beliefs and Attitudes about Sleep Scale-16(DBAS-16) and a general information questionnaire which was designed by researchers. Results 48.2% of patients with stable coronary heart disease reported poor sleep quality at home, and the total score of PSQI was (7.99 ± 4.061), the total score of DBAS was (47.44 ± 9.77). Univariate anova showed that age (F=14.567, P<0.01), gender (H=16.657, P<0.01), marital status (F=4.706, P=0.031), job status (F=15.738, P<0.01) and the number of comorbid diseases (F=4.674, P=0.003),are factors affecting sleep quality. Pearson correlation analysis showed that there were significantly negative correlation between PSQI and DBAS (r=-0.260, P<0.01). Multiple Linear Regression showed that sleep beliefs and attitudes, gender, age, the number of comorbid diseases were influencing factors of sleep quality (R2=0.247, F=17.907, P<0.01). Conclusions The sleep quality at home in patients with stable coronary heart disease was closely related to sleep beliefs and attitudes. Nurses should pay more attention to the sleep quality of patients, correct their incorrect sleep cognition timely, and improve their sleep quality.

ABSTRACT

Chimeric antigen receptor T (CAR-T) cell therapy is a novel cellular immunotherapy that is widely used to treat hematological malignancies, including acute leukemia, lymphoma, and multiple myeloma. Despite its remarkable clinical effects, this therapy has side effects that cannot be underestimated. Cytokine release syndrome (CRS) is one of the most clinically important and potentially life-threatening toxicities. This syndrome is a systemic immune storm that involves the mass cytokines releasing by activated immune cells. This phenomenon causes multisystem damages and sometimes even death. In this study, we reported the management of a patient with recurrent and refractory multiple myeloma and three patients with acute lymphocytic leukemia who suffered CRS during CAR-T treatment. The early application of tocilizumab, an anti-IL-6 receptor antibody, according to toxicity grading and clinical manifestation is recommended especially for patients who suffer continuous hyperpyrexia, hypotensive shock, acute respiratory failure, and whose CRS toxicities deteriorated rapidly. Moreover, low doses of dexamethasone (5-10 mg/day) were used for refractory CRS not responding to tocilizumab. The effective management of the toxicities associated with CRS will bring additional survival opportunities and improve the quality of life for patients with cancer.

ABSTRACT

Objective To investigate the significance of blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI) and ambulatory urodynamics monitoring (AUM) to find the cause of primary monosymptomatic nocturnal enuresis (PMNE) in children.Methods Thirty-seven children with PMNE (20 males and 17 females) were selected,with a mean age of (11.3 ±4.1) years old.A clinical management tool,3-day urination record,daytime BOLD-fMRI scan,conventional urodynamics (CUD) and AUM were performed respectively.Thirty-seven gender-age matched children(19 males,18 females) who would receive surgery treatment because of upper urinary tract disease and were confirmed to have no lower urinary tract dysfunction by CUD were enrolled as controls,with a mean age of (11.1 ± 2.9) years old,and 13 cases underwent BOLD-fMRI scanning.Results It was found that the ALFF value of the left middle frontal gyrus of PMNE was decreased and the ReHo value of the left superior occipital gyrus was increased compared with the control group by the resting BOLD-fMRI.The maximum voiding volume of PNME children was (303.11 ± 87.48) mL,the total urine volume at night was (568.65 ± 208.48) mL,and the nighttime bladder volume was (217.43 ± 81.53) mL.The incidence of maximum voiding volume reduction,nocturnal polyuria and decreased nocturnal bladder volume were 24.32% and 56.76%,and 64.86%,respectively.However,AUM results showed that maximum detrusor pressure in the PMNE group was (39.22 ± 7.78) cmH2O (1 cmH2O =0.098 kPa),which was statistically significantly higher than that in CUD (32.22 ±9.00) cmH2O,and the difference was statistically significant (P <0.05).In PMNE group,29 cases (78.37%) had detrusor overactivity (DO),which was significantly higher than that in CUD group [16 cases (43.24%)],and the difference was statistically significant(t =-3.047,P =0.004).CUD and AUM were all detected in children with DO,the frequency of DO detected by AUM was significantly higher than that detected by CUD[(2.00 ±0.55 times/h) vs.(1.38 ±0.50) times/h,P <0.05],and the maximum amplitude of detrusor pressure when DO occurring was significantly higher in AUM than in CUD [(19.56 ± 6.01) cmH2O vs.(14.38 ± 3.07) cmH2O],and the differences were statistically significant (all P < 0.05);however,there was no significant difference in bladder compliance detected by AUM or CUD (P > 0.05).Conclusions The abnormal functions of the left middle frontal gyrus and left superior occipital gyrus,nighttime DO and the decrease of bladder capacity at night are considered to be key causes of enuresis in children with PMNE.AUM and resting state BOLD-fMRI evaluations are helpful in differentiating the pathogenesis of PMNE.

ABSTRACT

Objective@#To compare the consistency of thyroid stimulating hormone (TSH) results from four chemiluminescence assays. @*Methods@#A total of 102 fresh serum samples from Peking Union Medical College Hospital during March 2018 and April 2018 were collected for precision evaluation and methodological comparison referring to CLSI EP15-A2 and EP9-A2 protocols. The levels of serum TSH were detected by Abbott i2000 (system A), Beckman DXI800 (system B), Siemens ADVIA Centaur XP (system C) and Roche e601 (system D) automatic chemiluminescence analyzers and their matching reagents, respectively. The obtained results were compared with the passing-bablok and Bland Altman methods. Taking 0.27 μIU/mL and 5.33 μIU/mL as the medical decision level, the expected bias of each detection system was compared. @*Results@#The precisions of systems A,B,C and D were 1.7%-3.3%, 2.3%- 3.9%,0.7%-2.3% and 0.6%-1.5%,respectively. The median (P 25,P 75) of TSH concentrations detected by systems A,B,C and D were 1.898 (0.518,4.809)μIU/mL, 2.819 (0.719,7.020)μIU/mL,2.502 (0.692,6.888)μIU/mL and 3.105 (0.886, 7.905)μIU/mL, respectively. The coefficients of determination (R 2 ) of regression equation were above 0.975 for 4 detection systems. The correlation coefficients (r), intercepts and slopes of 4 detection systems were 0.993 5-0.997 1, 0-0.06 and 0.59-1.15, respectively, and systems B and C had the best correlations with 1.02 of slope and 0 of intercept. The deviation plot showed that the bias% of 4 detection systems was between -48.1% and 17.3%. Among them, systems A and D had the largest bias, while systems B and C had the lowest bias. The expected bias of 4 detection systems at the medical decision level was -40.7%-37.2%. @*Conclusion@#The consistency between Beckman and Siemens TSH detection systems is good, while those of Roche and Abbott TSH detection systems are different from the other two.

Objective To investigate characteristics of Treponema pallidum (Tp)-induced macrophage-derived exosomes and its effect on the proliferation of human umbilical vein endothelial cells (HUVEC).Methods Tp strains were collected from the testis of male rabbit,which were infected with Tp (Nichols strain).The human mononuclear macrophages (THP-1) were induced into macrophages by incubation with propylene glycol methyl ether acetate (PMA),and then the macrophages were divided into 2 groups:experimental group incubated with Tp for 12 hours followed by 48-hour normal culture,and control group receiving normal culture.After the treatment,exosome suspensions were collected,and exosomes were extracted by differential centrifugation and exoEasy Maxi Kit.Transmission electron microscopy and Western blot analyses were performed to identify the exosomes,and nanoparticle tracking analysis (NTA) was conducted to measure the diameters and concentrations of exosomes.In vitro cultured HUVECs were divided into 3 groups,which were cultured with the 10 μl of suspensions containing exosomes derived from Tp-stimulated macrophages at a concentration of 4.5 × 108/ml (experimental group),10 μl of suspensions containing exosomes derived from untreated macrophages at a concentration of 4.5 × 108/ml (control group),and 10 μl of exosome eluents (exosome eluent group),respectively.After the treatment,confocal laser scanning microscopy was performed to observe the phagocytosis of exosomes of HUVECs,and cell counting kit-8 to evaluate the proliferative activity of HUVECs.Results The exosomes were saucer-like microvesicles with diameters of 30-100 nm under the transmission electron microscope.Western blot analyses showed that membrane proteins CD63,CD9 and CD81 were abundantly expressed by exosomes.Under the same conditions,NTA revealed that there were no significant differences in the particle diameter (u =1.90,P > 0.05) and concentration of exosomes (Z =-1.604,P =0.109) between the experimental group and the control group.After co-culture with HUVECs for 5 hours,confocal laser scanning microscopy showed scatteredly distributed exosomes with green fluorescence in the HUVECs in the experimental group and control group.After 12-hour co-culture with the exosome suspensions,the proliferative activity of HUVECs was significantly higher in the experimental group and the control group than in the exosome eluent group (both P < 0.05).After 24-and 48-hour treatment with exosome suspensions,the proliferative activity of HUVECs in the control group was still significantly increased compared with that in the exosome eluent group,and peaked at 48 hours (all P < 0.05).Moreover,there were no significant differences in the proliferative activity of HUVECs between the experimental group and exosome eluent group at 24 and 48 hours (both P > 0.05).At 72 hours,no significant differences in the proliferative activity of HUVECs were observed among the experimental group,the control group and the exosome eluent group (all P > 0.05).Conclusions The exosomes secreted by THP-1 cells-derived macrophages evidently increased the proliferative activity of HUVECs within 48 hours,which peaked at 48 hours.After the stimulation with Tp,the exosomes secreted by THP-1 cells-derived macrophages were similar to those without Tp stimulation in morphology,size and concentration,and only increased the proliferative activity of HUVECs within 12 hours.

ABSTRACT

An asymptomatic 71-year-old woman was admitted to the hospital due to aneurysm of visceral artery. CT angiography revealed that she possessed a hepatosplenic artery aneurysm with hepatosplenomesenteric trunk anomaly. The aneurysm was big with diameter about 28 mm, and is very adjacent to the superior mensenteric artery. The neck of the aneurysm is wide (the diameter of the neck was 5.5-6.0 mm) and short (length of the proximal landing zone was about 2.0 mm). The patient received endovascular reconstruction of the hepatosplenic artery and coil embolization of the aneurysm, and got satisfactory result.

ABSTRACT

Objective To identify the risk factors associated with recurrent urinary tract infection (RUTI) in children with neurogenic bladders (NB) who received clean intermittent catheterization (CIC) in order to provide recommendations for reducing the risk of RUTI.Methods Records of 184 children with NB managed by CIC at the Department of Urology Surgery,the First Affiliated Hospital of Zhengzhou University from July 2011 to September 2015 were reviewed and analyzed.According to UTI incidence,they were divided into 2 groups as occasional UTI group (0-1 time/year,OUTI group) and RUTI group (> 1 time/year).The clinical and urodynamic data were compared between 2 groups,and the risk factors were identified by regression analysis.Results Of the total patients,147 patients (79.9%) were diagnosed as OUTI and 37 cases (20.1%) as RUTI.Median follow-up lasted for average 27 months (12-39 months).The characteristics of RUTI group was indicated significantly in the study,which included increasing age(7.4 years old vs.5.9 years old),a higher level of spinal lesions,and more vesicoureteral reflux(VUR),and there were significant differences in bladder wall thickness(4.7 cm vs.3.6 cm) and lower bladder compliance compared with RUTI group (all P < 0.05).But there was no statistical significance in gender,antibiotics,hydronephrosis,incontinence,bladder capacity,detrusor overactivity,detrusor sphincter dyssynergia and detrusor leakage point pressure between 2 groups (all P > 0.05).Increasing age,increased bladder wall thickness,lower bladder com-pliance and the presence of VUR were independent risk factors associated with RUTI group (all P < 0.05).Conclusions Increasing age,increasing bladder wall thickness,lower bladder compliance and VUR are the risk factors for RUTI in NB children managed with CIC.It is necessary to follow up video-urodynamic and ultrasound findings in order to identify the high-risk patients and provide the evidence for preventing RUTI.

ABSTRACT

Objective To investigate mechanisms underlying the regulation of the permeability of vascular endothelial cells by the Treponema pallidum membrane protein Tpp47.Methods Human umbilical vascular endothelial cell (HUVEC) monolayers were established as a model,and were directly cultured with the presence of recombinant Tpp47 protein (rTpp47-treated group),or boiled and inactivated rTpp47 (negative control group).Some HUVEC monolayers,which were pretreated with the RhoA/ROCK signal pathway inhibitor Y-27632 for 30 minutes and then cultured with the presence of rTpp47,served as the pretreatment group.After 1-and 4-hour additional culture,enzymelinked immunosorbent assay (ELISA) was performed to estimate the permeability of these cell monolayers to horseradish peroxidase (HRP).After 12 hours of culture,rhodamine-phalloidin was used to stain cytoskeletal proteins,and confocal laser scanning microscopy was performed to observe the arrangement of the cytoskeletal protein F-actin.Western-blot analysis was conducted to measure the expressions of RhoA in HUVECs treated with rTpp47 or inactivated rTpp47.Results The supernatant level of HRP (expressed as the absorbance value at 450 nm) was significantly higher in the rTpp47-treated group than in the negative control group (0.81 ± 0.10 vs.0.39 ± 0.09,P < 0.05),but no significant difference was observed between the pretreatment group (0.51 ± 0.10) and rTpp47-treated group or negative control group (both P > 0.05) after 1-hour culture.Similarly,the rTpp47-treated group showed significantly increased levels of HRP compared with the pretreatment group and negative control group (2.31-± 0.14 vs.1.21 ± 0.12 and 0.73 ± 0.12,both P < 0.05),while there was no significant difference between the pretreatment group and negative control group after 4-hour culture.The expression of RhoA in HUVECs treated with rTpp47 was significantly higher than that in those treated with inactivated rTpp47.Confocal laser scanning microscopy showed that rTpp47 treatment led to the rearrangement of F-actin in HUVECs followed by the formation of stress fibers in cytoplasm,while Y-27632 could partly inhibit the rearrangement of F-actin.Conclusion The recombinant Treponema pallidum membrane protein Tpp47 can regulate the permeability of vascular endothelial cells through the RhoA/ROCK signal pathway.
