ABSTRACT

ObjectiveTo observe the clinical efficacy of modified Tuoli Xiaodusan (TLXDS) in adjuvant treatment of Helicobacter pylori (Hp)-positive peptic ulcer (PU) with cold-heat complex syndrome and explore its regulating effect on invasive/protective factors. MethodA total of 136 patients were randomly assigned into the control group (68 cases, including 4 cases missing, 3 cases eliminated, and 61 cases completed) and the TLXDS group (68 cases, including 4 cases missing, 1 case eliminated, and 63 cases completed). Both groups adopted the quadruple therapy of acid suppression and Hp eradication. The patients in the control group received Weinai'an capsules orally at 4 capsules/time and 3 times/day, and those in the TLXDS group took modified TLXDS orally at 1 dose/day. The administration of both groups lasted for 8 consecutive weeks and the follow-up lasted for 12 months. Electronic gastroscopy was carried out before and after treatment for evaluating the healing of ulcer, the score of mucosal morphology, and the maturity of regenerated mucosa. The Hp infection and the score of cold-heat complex syndrome were evaluated before and after treatment. The serum levels of gastrin (GAS), prostaglandin E2 (PGE2), pepsinogen (PG)-Ⅰ, PG-Ⅱ, epidermal growth factor (EGF), and trefoil factor 2 (TFF-2) were determined before and after therapy. The recurrence of Hp and PU was recorded, and the drug safety was evaluated. ResultAfter treatment, the mucosal morphology score and the traditional Chinese medicine (TCM) syndrome score in the TLXDS group were lower than those in the control group (P<0.01). The levels of GAS, PG-Ⅰ, and PG-Ⅱ in the TLXDS group were lower than those in the control group (P<0.01), whereas those of PGE2, EGF, and TFF-2 showed an opposite trend (P<0.01). After treatment, the Hp eradication rate in the TLXDS group was 95.24% (60/63), higher than that (83.61%, 51/61) in the control group (χ2=4.467, P<0.05). The total effective rate of TCM syndromes in the TLXDS group was 98.41% (62/63), higher than that (81.97%, 50/61) in the control group (χ2=9.589, P<0.01). The total effective rate of the TLXDS group under gastroscopy was 98.41% (62/63), higher than that (86.89%, 53/61) in the control group (χ2=4.525, P<0.05). The excellent and good rate of regenerated mucosal maturity in the TLXDS group was 92.06% (58/63), also higher than that (73.77%, 45/61) in the control group (χ2=7.372, P<0.01). After 12 months of follow-up, the TLXDS group had lower PU recurrence rate [19.05% (12/63) vs 37.70% (23/61), χ2=5.325, P<0.05] and lower Hp recurrence rate [15.00% (9/60) vs 33.33% (17/51), χ2=5.165, P<0.05) than the control group. No adverse reactions related to TLXDS were detected. ConclusionModified TLXDS-assisted quadruple therapy demonstrates significant short-term clinical efficacy and high Hp eradication rate for Hp-positive PU (cold-heat complex syndrome) patients. Moreover, it can adjust the levels of invasive/protective factors to facilitate ulcer healing and reduce the recurrence rates of Hp and PU in a long term, with good clinical safety.

ABSTRACT

BACKGROUND@#The current deep learning diagnosis of breast masses is mainly reflected by the diagnosis of benign and malignant lesions. In China, breast masses are divided into four categories according to the treatment method: inflammatory masses, adenosis, benign tumors, and malignant tumors. These categorizations are important for guiding clinical treatment. In this study, we aimed to develop a convolutional neural network (CNN) for classification of these four breast mass types using ultrasound (US) images.@*METHODS@#Taking breast biopsy or pathological examinations as the reference standard, CNNs were used to establish models for the four-way classification of 3623 breast cancer patients from 13 centers. The patients were randomly divided into training and test groups (n = 1810 vs. n = 1813). Separate models were created for two-dimensional (2D) images only, 2D and color Doppler flow imaging (2D-CDFI), and 2D-CDFI and pulsed wave Doppler (2D-CDFI-PW) images. The performance of these three models was compared using sensitivity, specificity, area under receiver operating characteristic curve (AUC), positive (PPV) and negative predictive values (NPV), positive (LR+) and negative likelihood ratios (LR-), and the performance of the 2D model was further compared between masses of different sizes with above statistical indicators, between images from different hospitals with AUC, and with the performance of 37 radiologists.@*RESULTS@#The accuracies of the 2D, 2D-CDFI, and 2D-CDFI-PW models on the test set were 87.9%, 89.2%, and 88.7%, respectively. The AUCs for classification of benign tumors, malignant tumors, inflammatory masses, and adenosis were 0.90, 0.91, 0.90, and 0.89, respectively (95% confidence intervals [CIs], 0.87-0.91, 0.89-0.92, 0.87-0.91, and 0.86-0.90). The 2D-CDFI model showed better accuracy (89.2%) on the test set than the 2D (87.9%) and 2D-CDFI-PW (88.7%) models. The 2D model showed accuracy of 81.7% on breast masses ≤1 cm and 82.3% on breast masses >1 cm; there was a significant difference between the two groups (P < 0.001). The accuracy of the CNN classifications for the test set (89.2%) was significantly higher than that of all the radiologists (30%).@*CONCLUSIONS@#The CNN may have high accuracy for classification of US images of breast masses and perform significantly better than human radiologists.@*TRIAL REGISTRATION@#Chictr.org, ChiCTR1900021375; http://www.chictr.org.cn/showproj.aspx?proj=33139.

ABSTRACT

Objective@# To identify the differentially expressed miRNAs in the exosomes secreted from γ-ray irradiated cells and provide new clues in disclosing the mechanisms of radiation-induced bystander effects.@*Methods@#The human bronchial epithelial cells (BEP2D) were irradiated with 60Co γ-rays, and the exosomes were collected by ultracentrifugation from the culture medium of 2 Gy-irradiated cells and non-irradiated control. The exosomes were identified by an electron microscopy. The miRNA microarray technique was used to analyze the miRNA expression profiles in the exosomes. qRT-PCR was used to verify the miRNAs expression. The functional pathways of miRNAs targeting genes were predicted by informatic analysis using the databases of TargetScan, miRanda, GO and KEGG.@*Results@#Sixteen miRNA with significantly increased expression (P<0.05) were identified in the exosomes of BEP2D cells at 4 h post-2 Gy irradiation as compared with the non-irradiated control cells, among which miR-100-5p, miR-1246, miR-29b-3p, and miR-7-5p were further confirmed to be unregulated by qRT-PCR assay (P<0.05). Meanwhile, the expression changes of above-mentioned four miRNAs were also investigated in the irradiated cells. The data indicated the expression was significantly increased at 2 h post-2 Gy irradiation for the miR-100-5p, miR-1246, miR-29b-3p in addition to miR-7-5p. However, all these four miRNAs were downregulated in the cells at 4 h post-irradiation and then gradually recovered. Bioinformatics analysis showed that the targeted genes of these differentially expressed miRNAs might participate in the biological processes and signal pathways of cell adhesion, mTOR signal pathway, chromatin modification, HR and NHEJ pathways of DNA repair and so on.@*Conclusions@# Radiation-inducible miRNAs have been identified in the exosomes from the irradiated BEP2D cells. The target genes of these miRNAs play roles in a series of important biological processes and functional pathways, which provides new clues in elucidating the mechanisms of radiation-induced bystander effects.

ABSTRACT

Objective To study the changes in miRNAs expression in the exosomes of human umbilical vein endothelial cells(HUVECs) after 60 Co γ-rays expose using microRNA(miRNA) chips and bioinformatics techniques so as to provide new clues to the mechanism of radiation-induced vascular tissue injury and its bystander effects.Methods HUVECs exosomes were collected in the control and 4 Gy irradiated cells by ultra-high-speed centrifugation,and further confirmed using transmission electron microscopy (TEM) and Western blotting of exosomes biomarkers.miRNA microarray was used to analyze miRNA expression profiles of exosomes and cells.Also,real-time quantitative PCR(qRT-PCR) was used to verify differentially expressed miRNAs,and the miRDB and TargetScan were performed to predict the target genes of the differentially expressed miRNAs.Bioinformatics analysis was performed using DAVID,KEGG and other online tools.Results Compared with the control exosomes from non-irradiated HUVECs,miRNA microarray analysis revealed that 5 up-regulated,and 13 down-regulated miRNAs were identified in the exosomes from HUVECs at 0.5 h after 4 Gy-irradiation,and 16 up-regulated and 5 down-regulated miRNAs at 2 h after 4 Gy-irradiation.Moreover,38 and 85 miRNAs were differentially expressed respectively in the HUVECs at 0.5 h and 2 h after radiation.The difference was statistically significant(P<0.01).The results of bioinformatics showed that these miRNAs might exert the radiation-induced bystander effect (RIBE) by regulating MAPK signal pathways,RAS and PI3K-Akt signal pathways.Conclusion The ionizing radiation injury significantly alters the components and expression levels of exosomal miRNAs,which play important roles in regulating the signal pathways in response to radiation.

ABSTRACT

It has been shown that mitochondria not only control their own Ca(2+) concentration ([Ca(2+)]), but also exert an influence over Ca(2+) signaling of the entire cell, including the endoplasmic reticulum or the sarcoplasmic reticulum, the plasma membrane, and the nucleus. That is to say, mitochondria couple cellular metabolic state with Ca(2+) transport processes. This review focuses on the ways in which the mitochondrial Ca(2+) handling system provides integrity and modulation for the cell to cope with the complex actions throughout its life cycle, enumerates some indeterminate aspects about it, and finally, prospects directions of future research.

ABSTRACT

PURPOSE: We retrospectively investigated how patients age and prostate volume influence on the cancer detection rate in Korean men with prostate-specific antigen (PSA) levels of 4.0 to 10.0ng/ml. MATERIALS AND METHODS: 791 Korean men who underwent transrectal ultrasound guided prostate biopsies (TRBx) at 12 medical centers were analyzed retrospectively during the previous 10 years. TRBx were performed in cases with PSA levels of 4.0 to 10.0ng/ml. The biopsy-proven cancer patient group was compared to the non-cancer patient group according to age, PSA, prostate volume and PSAD. RESULTS: Among the 791 patients who underwent TRBx, prostate cancer was detected in 123 patients (15.5%). The mean age (cancer group vs non-cancer group=69.1 vs 63.8 year-old), prostate volume (38.0 vs 42.5ml, respectively) and PSAD (0.21 vs 0.18ng/ml/ml, respectively) were found in statistically significant between the two groups. The cancer detection rate (20.1%) in the small prostate (less than 40ml) was significantly higher than that (10.3%) of the large prostate. The cancer detection rate was significantly increased with age: from 14.4% for the 50 to 59 year-old patients to 31.6% for the 80 or more year-old patients. CONCLUSIONS: The cancer detection rate in Korean men with a gray zone PSA level is lower than that of Caucasians. However, regarding the detection of prostate cancer in Korean men, the older age group and the patients with less than 40ml of prostate volume among the patients with gray zone PSA levels are considered as the important factors to decide whether biopsy of prostate is needed.

ABSTRACT

PURPOSE: The incidence of prostate cancer is increasing in Korea, but compared with western counties, the incidence is relatively low. The detection rate of prostate cancer, according to the serum prostate-specific antigen (PSA) level, is reportedly different in Korean men, but this remains to be confirmed. We retrospectively reviewed the data of prostate biopsies, and evaluated the detection rate of prostate cancer from biopsies, according to the serum PSA level in Korean men. MATERIALS AND METHODS: We retrospectively reviewed the results of 2,422 Korean men who had undergone prostate biopsies at 12 medical centers. Prostate biopsies were performed in cases of high PSA levels, greater than 4ng/ml, or abnormal findings on digital rectal examination. RESULTS: Of the 2,422 men, 39.7% had a positive biopsy. With PSA levels between 4 and 10ng/ml, the detection rate of prostate cancer was 15.9%. This rate was similar to that of the Japanese (15.8%), but quite different from that of American men (25%). With PSA levels above 10ng/ml, 59.5% of men had a positive biopsy. For PSA levels > or= 4ng/ml and > or= 10ng/ml, the detection rates were 42.1 and 59.5%, respectively. CONCLUSIONS: When the serum PSA levels were divided into 4 subdivisions (4.0-10.0, 10.0-20.0 and 20.0-100.0ng/ml and more than 100.0ng/ml), the detection rates were 15.9, 34.1, 66.2 and 93.8%, respectively.

ABSTRACT

This study was conducted to determine the effect of pregnanolone (PGN) on blood pressure of a rat model of stress-induced hypertension (SIH). This model was established by applying electric shock to animal feet together with noise. PGN was administered intraperitoneally at 0.24 mg/kg.d(-1) and blood pressure, angiotensin II (Ang II) levels, and the expression of Fos-like protein immunoreactive (FLI) neurons in brain areas were determined. Rats were randomly divided into five groups: (1) control, (2) stressed for 1 h, (3) stressed for 1 h after PGN pretreatment, (4) stressed for a 2 h session, twice a day, for 15 d, and (5) stressed for a 2 h session after PGN pretreatment, twice a day, for 15 d. The results showed that increased systolic pressure of tail artery caused by a 15-d stress treatment was significantly reduced by PGN pretreatment (P<0.001). Ang II levels, measured by radioactive immunoreactivity, were significantly elevated (P<0.001) after the rats were stressed for 1 h or 15 d, the Ang II level was significantly reduced by PGN treatment in both 1 h and 15 d stress groups (P<0.05). Only a small number of FLI neurons were found in the brain areas of the control group, 15 d stress group, and 15 d stress with PGN group. In the 1 h stress group, more FLI neurons were found in the lateral habenular nucleus, the medial habenular nucleus, the paraventricular nucleus, the central nucleus of amgydaloid and the lateral hypothalamus compared with the control group. PGN pretreatment significantly prevented the increase in the number of FLI neurons. These results indicate that PGN pretreatment prevents elevation of tail artery systolic pressure in SIH rats and that this effect of PGN may be mediated through reducing Ang II level and inhibiting the activity of cardiovascular center involved in stress.

ABSTRACT

We report a case of myxoid sarcoma in the left atrium, which was diagnosed as benign myxoma on preoperative echocardiography. At operation, semisolid mobile masses were found that attached with broad stalk to the posterior left atrial wall and that invaded into the left pulmonary vein and the anterior mitral leaflet. The patient underwent excision of left atrial tumor masses, mitral valve replacement, and left pneumonectomy. The histological diagnosis was undifferentiated cardiac myxoid sarcoma. Although echocardiography lead to the choice of diagnostic test of intra-atrial tumor, magnetic resonance imaging, computed tomography, and intraoperative transesophageal echocardiography may be needed for differential diagnosis, with indeterminate malignant findings on preoperative transthoracic echocardiography. Anesthesiologists are often confronted with cases that are unusual, therefore preoperative understanding of the cases are important for safe anesthetic management.

ABSTRACT

OBJECTIVE: To investigate the immediate effect of dorsal penile nerve (DPN) stimulation on detrusor pressure (Pdet) and blood pressure (BP) during hyper-reflexic contractions of the bladder in patients with cervical spinal cord injury (SCI). METHOD: The subjects were eight male patients with cervical SCI who had symptoms of autonomic dysreflexia. During water-cystometry, BP was monitored using an intra-arterial catheter into the radial artery, and was recorded simultaneously with the Pdet. Electrical stimulation was applied to the DPN, using surface electrodes each time a bladder contraction was detected. Baseline BP and BP at the first and the last hyper-reflexic contractions of bladder were measured with Pdet, respectively. RESULTS: As Pdet increased, the BP increased in all cases. The reflex contractions of the bladder were effectively suppressed by DPN stimulation, and as the Pdet decreased during stimulation, radial arterial pressure also decreased immediately and significantly. CONCLUSION: DPN stimulation can lower both Pdet and the elevated BP.

ABSTRACT

OBJECTIVE: To evaluate the inhibition effects of hyper-reflexic detrusor activity by sacral afferent nerve stimulation in spinal cord injury (SCI) patients. METHOD: The subjects were thirteen patients with SCI who had symptoms of urinary incontinence, because of hyper-reflexic bladder contractions. According to the level and severity of injury, the patients were divided into groups of tetraplegia/paraplegia and complete/incomplete. We applied dorsal penile nerve (DPN) stimulation using portable stimulator during the continuous bladder filling. Stimulation parameters were biphasic rectangular pulses of 25 Hz frequency, 250 microseconds pulse width. Stimulation intensity was twice the threshold of pudendo-anal reflex. The one minute stimulation was repeated to every reflex contraction during the cystometry. Immediate suppressive effect of DPN was analyzed. RESULTS: Of 13 patients who had a reflex bladder, hyper-reflexic detrusor contractions were suppressed effectively in 12 by DPN stimulation. The suppressive effect in groups of level and severity was not statistically significant. CONCLUSION: DPN stimulation for inhibition of hyper-reflexic bladder contraction is an adjunctive method of incontinence management in SCI patients of different level and severity.

ABSTRACT

Rectal stricture is an occasional complication of abdominoperineal pull-through and low anterior resection of the rectum and irradiation injury. Although the causes and pathogenesis of this phenomenon are poorly understood, various techniques for stricture dilatation have been described. In this article, we present two cases of severe postoperative rectal stricture that were not amenable to conventional methods of dilation but were succesfully managed by transanal electroresection using endoscopic transurethral electroreectoscope.
