RESUMEN

Mental health disparities between racial/ethnic minority groups and non-Latinx Whites in the United States persist despite significant efforts aimed at decreasing these disparities. Efforts to address mental health disparities have largely focused on individual (e.g., stigma, help-seeking, health behaviors) and structural (e.g., public policy, interventions, addressing poverty) level factors. In contrast, this paper considers how processes at the interactional level (i.e., interactions between patients and providers) are also an important contributor to racial/ethnic disparities in mental health. Specifically, social psychological research has demonstrated how biases, including stereotypes, prejudice, and discrimination, can affect patient-provider interactions and contribute to mental health disparities. This narrative review of empirical studies that examine interactional processes between patients and mental health providers identified eleven studies to be included. Concepts represented in the studies are summarized and additional frameworks that can help explain how disparities are maintained are proposed. Last of all, practical suggestions for mitigating provider bias during patient-provider interactions are provided based on the findings from the narrative review.

RESUMEN

We retrospectively analyzed the clinical data of seven patients (four men and three women) with primary hyperoxaluria (PH) type 1 (PH1) in the Department of Nephrology of Zhongda Hospital, Southeast University from January 2018 to October 2023. The mean age at disease onset was 32.1 (range: 26-42) years. The mean age at diagnosis was 40.6 (range: 28-51) years. All patients initially had kidney stones, and three patients were found to have renal insufficiency at the time of disease onset. Among them, two patients underwent hemodialysis immediately. Symptoms at the first visit included bone pain (n=7), joint pain or deformity (n=5), fatigue (n=5), hypotension (n=3), and subcutaneous nodules (n=2). Four patients had a family history of PH. All patients had varying degrees of anemia (60-114 g/L), significant hypoalbuminemia (16.5-32.1 g/L), and hypercoagulable state (D-dimer: 2 230-12 781 µg/L). Seven patients received maintenance hemodialysis; their mean age was 37.7 (range: 26-50) years. The mean duration from disease onset to hemodialysis was 5.6 (range: 0-20) years. Five patients repeatedly experienced dialysis access dysfunction. Three patients underwent kidney transplantation before a diagnosis was made, and all transplanted kidneys lost function due to oxalate deposition. The mean follow-up duration was 14.43 (range: 4-38) months. Unfortunately, one patient died. All seven patients underwent computed tomography of the abdomen. All patients suffered skeletal abnormalities, bilateral nephrolithiasis, and nephrocalcinosis. Six patients carried AGXT gene mutations, including four compound heterozygous mutations and two pure homozygous mutations.The mutation sites included: c.823-824dup.AG (p.S275Rfs*38)(exon 8), c.815-816ins.GA (p.S275Rfs*38)(exon 8), c.595G>A (p.G199S) (exon 5), c.32C>G (p.P11R) (exon 1), and c.638C>T (p.A213V)(exon 6). According to the American College of Medical Genetics and Genomics guidelines, two loci were identified as likely pathogenic variants, seven were identified as pathogenic variants, and one locus was identified as having uncertain significance. In addition, patients 1 and 4 underwent skin biopsy, patient 2 underwent renal transplant biopsy, and patient 3 underwent bone marrow biopsy. Interestingly, significant oxalate deposition was found in the tissues. Therefore, PH1 is a rare autosomal recessive inherited disease. This study not only enhanced the understanding of the clinical characteristics of PH1 patients but also had great significance in early diagnosis and treatment of the disease.

RESUMEN

AIM: To describe the experience of endovascular treatment (EVT) of acute ischaemic stroke caused by isolated internal carotid artery (ICA) occlusion, with emphasis on treatment strategies, outcomes, and prognostic factors. MATERIALS AND METHODS: A retrospective examination was performed of 66 consecutive patients with acute moderate-to-severe stroke who underwent EVT for isolated ICA occlusion from July 2016 to June 2021. The modified thrombolysis in cerebral ischaemia (mTICI) score was used to evaluate reperfusion outcomes. A multivariate analysis was performed to identify risk factors associated with poor 90-day outcome (modified Rankin Scale [mRS] 3-6). RESULTS: The National Institutes of Health Stroke Scale (NIHSS) median score of the 66 patients at admission was 15. Twelve patients (18.2%) showed thrombus migration to the M1 segment or proximal M2 during EVT and underwent additional intracranial thrombectomy. Successful reperfusion (mTICI 2b-3) was achieved in 60 patients (90.9%) and complete reperfusion (mTICI 3) in 42 (63.6%). A poor functional outcome was seen in 27 patients (40.9%). The rate of 90-day mortality was 9.1% (6/66). Higher NIHSS scores and a lower Alberta Stroke Program Early CT Score (ASPECTS) were independently associated with poor outcomes. Complete reperfusion was the only treatment factor with a significant predictive value (adjusted odds ratio [OR] 0.03; 95% CI = 0.01 to 0.25; p=0.001). CONCLUSION: Endovascular therapy is safe and effective in patients with acute ischaemic stroke due to isolated ICA occlusion. Prevention of thrombus migration and complete reperfusion should be the aim of EVT.

RESUMEN

Objective: To compare the clinical outcomes of endovascular therapy in acute stroke patients with anterior circulation tandem occlusions caused by atherosclerosis or dissection. Methods: A retrospective cohort study. A total of 98 patients with anterior circulation tandem lesions undergoing endovascular therapy in the Wuhan NO.1 Hospital (March 2016 to March 2022) were analyzed. Median age was 64(55,71) years old, and 82.7% (81/98 cases) were males. According to the lesion etiology, the patients were divided into atherosclerosis and dissection groups. The differences in clinical outcomes between the two groups were investigated, including favorable 90-day functional outcome (modified Rankin Scale score of 0-2), successful reperfusion (modified Thrombolysis in Cerebrovascular Infarction score of 2b-3), symptomatic intracranial hemorrhage, stroke-associated pneumonia, 90-day all-cause mortality, and average hospitalization days. Logistic regression analysis was used to adjust for potential confounders affecting functional outcomes in both groups, and to determine odds ratios and 95% confidence intervals. Results: Seventy-one patients were grouped into the atherosclerotic cause and 27 into the dissection cause cohorts. The rate of favorable 90-day functional outcome was 43.7% (31/71 cases) in the atherosclerosis group versus 55.6% (15/27 cases) in the dissection group (adjusted odds ratio=1.339; 95% confidence interval, 0.374-4.798; P=0.654). No significant differences were found in other clinical outcomes between the two groups (all P>0.05). Conclusion: The clinical prognosis of patients with tandem lesions caused by atherosclerotic stenosis or artery dissection was similar after endovascular therapy. Future studies are still needed to verify our results.

RESUMEN

Objective: To investigate the efficacy and safety of CT-guided radiofrequency ablation of posterior root of spinal nerve in the treatment of postherpetic neuralgia (PHN). Methods: A total of 102 PHN patients (42 males and 60 females) aged (69.7±9.4) years who underwent CT-guided radiofrequency ablation of posterior root of spinal nerve in the Department of Pain Medicine of the Affiliated Hospital of Jiaxing University from January 2017 to April 2020 were retrospectively included. Patients were followed up, and numerical rating scale (NRS) score, Pittsburgh sleep quality index (PSQI), satisfaction score and complications before surgery (T0) and at 1 d (T1), 3 months (T2), 6 months (T3), 9 months (T4) and 12 months (T5) after surgery were recorded. Results: The NRS score of PHN patients at T0, T1, T2, T3, T4, and T5 [M(Q1, Q3)] was 6(6, 7), 2(2, 3), 3(2, 4), 3(2, 4), 2(1, 4), 2(1, 4), respectively. Likewise, the PSQI score [M(Q1, Q3)] at aforementioned time points was 14(13, 16), 4(3, 6), 6(4, 8), 5(4, 6), 4(2, 8), 4(2, 9), respectively. Compared with T0, the NRS and PSQI scores at all time points from T1 to T5 were lower, with statistically significant differences (all P<0.001). The overall effective rate of surgery at 1 year postoperatively was 71.6% (73/102) with a satisfaction score of 8(5, 9), and the recurrence rate was 14.7% (15/102) with a recurrence time of (7.5±0.8) months. The main postoperative complication was numbness, with an incidence of 86.0% (88/102), and the degree of numbness gradually decreased with time. Conclusion: CT-guided radiofrequency ablation of posterior root of spinal nerve for PHN has a high effective rate and a low recurrence rate, with high safety profile, and may be a feasible surgical option for the treatment of PHN.

RESUMEN

Objective: To investigate the efficacy and safety of pulsed radiofrequency of dorsal root ganglion combined with ozone injection on acute herpes zoster neuralgia in the neck and upper extremities. Methods: A total of 110 patients with acute phase herpes zoster neuralgia in the neck and upper extremities treated in the Department of Pain of Jiaxing First Hospital from January 2019 to February 2020 were retrospectively included. The patients were divided into two groups according to different treatment modalities: the pulsed radiofrequency group (group A, n=68) and the pulsed radiofrequency combined with ozone injection group (group B, n=42). In group A, there were 40 males and 28 females, aged (71.9±9.9) years, while group B consisted of 23 males and 19 females, aged (66.3±16.9) years. Patients were followed up, and numerical rating scale (NRS) score, dose of adjuvant gabapentin, incidence of clinically significant postherpetic neuralgia (PHN) and adverse effects were recorded preoperatively (T0) and at 1 d (T1), 3 d (T2), 1 week (T3), 1 month (T4), 2 months (T5), and 3 months (T6) postoperatively. Results: The NRS score of patients [M (Q1, Q3)] in group A at time points T0, T1, T2, T3, T4, T5 and T6 was 6 (6, 6), 2 (2, 2), 3 (3, 4), 3 (2, 3), 2 (2, 3), 2 (1, 3) , 1 (0, 2), respectively, while the NRS score at aforementioned time points in group B was 6 (6, 6), 2 (1, 2), 3 (3, 4), 3 (2, 3), 2 (2, 3), 2 (1, 3), 1 (0, 2), respectively. Compared with preoperative NRS scores, NRS scores decreased in both groups at all postoperative time points (all P<0.05). Compared with group A, the NRS scores of group B at time points T3, T4, T5, and T6 decreased more significantly, with statistically significant differences (all P<0.05). The dose of gabapentin in group A [M (Q1, Q3)] was 0.6 (0.6, 0.6), 0.3 (0.3, 0.6), 0.3 (0.0, 0.3) and 0.0 (0.0, 0.3) mg/d at time points T0, T4, T5, and T6, respectively, and 0.6 (0.6, 0.6), 0.3 (0.2, 0.3), 0.0 (0.0, 0.3) 0.0 (0.0, 0.0) mg/d in patients in group B, respectively. Compared with the preoperative period, the doses of gabapentin taken by patients in both groups reduced significantly at all postoperative time points (all P<0.05). Moreover, compared with group A, the gabapentin dose in group B decreased more significantly at time points T4, T5, and T6, with statistically significant differences (all P<0.05). The incidence of clinically significant PHN was 25.0% (17/68) and 7.1% (3/42) in groups A and B, respectively, and the differences were statistically significant (P=0.018). No serious adverse effects such as pneumothorax, spinal cord injury and hematoma were observed during the treatment period in both groups. Conclusion: Pulsed radiofrequency of dorsal root ganglion combined with ozone injection is safer and more effective for the treatment of acute phase herpes zoster neuralgia in the neck and upper extremities, and it can reduce the incidence of clinically significant PHN, with high safety profile.

RESUMEN

Objective: To investigate the causes of misdiagnosis of suprasellar arachnoid cysts, analyze its characteristics and put forward the diagnostic basis and differential points. Methods: The clinical data fo 97 cases of suprasellar arachnoid cysts diagnosed and treated in the neurosurgery department of Beijing Tiantan Hospital and Hebei General Hospital from March 2015 to March 2019 were analyzed retrospectively. All patients underwent CT and MRI scans with obstructive hydrocephalus. 13 cases were misdiagnosed, including 7 males and 6 females. First visit age 1-31 years old, with an average age of 6.3 years. There were 10 patients younger than 6 years old. The remaining 15-year-old patients, 31-year-old patients and 26-year-old patients each have one case. 11 cases were misdiagnosed as obstructive hydrocephalus, 2 cases as cystic craniopharyngioma. Results: 13 cases were misdiagnosed and mistreated, 11 cases were treated with intraventricular and abdominal shunt, 9 cases were treated with neuroendoscopy and recovered well. One cases of intracranial hematomas underwent craniotomy again, the hematomas were removed again and the bone slise were decompressed. One case had fissured stable after shunt. There were no operative deaths and no complications in this group. After endoscopic reoperation, CT and/or MRI scans showed that the ventricle narrowed in varying degrees, some of them returned to normal size and the flow of cerebrospinal fluid (cerebrospinal fluid) was unobstruct at the end of magnetic resonance cerebrospinal fluid angiography (MRI) fistula after endoscopic reoperation. Conclusions: The incidence of suprasellar arachnoid cysts is low, it is rare in clinic and it is easy to misdiagnose and mistreate. At present, it is recognized that the best treatment methods are partial resection of endoscope cyst wall, cyst ventricle fistula and third ventricle floor fisthla.

RESUMEN

Objective: To investigate the role and regulation mechanism of X box binding protein 1 (XBP1) for hypoxia/reoxygenation(H/R) injury in mouse renal tubular epithelial cells (TCMK-1) through thioredoxin interacting protein (TXNIP)-nucleotide-binding domain (NOD)-like receptor protein (TXNIP-NLRP3) signaling pathway. Methods: The cells were divided into 4 groups: si-NC group transfected with negative control siRNA (si-NC), si-XBP1 group transfected with siRNA targeting XBP1 (si-XBP1), si-NC+H/R group transfected with si-NC and exposed to H/R, and si-XBP1+H/R group transfected with si-XBP1 and exposed to H/R. The Annexin Ⅴ/PI double-staining method was used to detect cell apoptosis; The mitochondrial membrane potential (MMP) was determined by using JC-1 dye; The mitochondrial reactive oxygen species (mROS) was assessed by using MitoSOX™ dye. The interference efficiency of XBP1 was tested by Western blotting and quantitative real-time polymerase chain reaction. The expression levels of TXNIP, NLRP3 and IL-1ß protein were detected by Western blotting. The colocalization of mitochondria and TXNIP was detected by double-labeling immunofluorescent staining. The intergroup difference was compared by using an independent samples t-test. Results: Compared with the si-NC group, more mROS, apoptosis and lower MMP were observed in si-NC+H/R group. Compared with the si-NC+H/R group, less apoptosis (12.08±0.51 vs 19.01±1.80, P<0.05), mROS (34.63±0.64 vs 48.17±1.84, P<0.01) and higher MMP (1.03±0.11 vs 0.45±0.08, P<0.05) were observed in si-XBP1+H/R group. Down-regulation of XBP1U (protein: 1.31±0.18 vs 0.23±0.02, P<0.01; mRNA: 1.12±0.07 vs 0.38±0.01, P<0.001) and XBP1S (protein: 1.13±0.17 vs 0.28±0.07, P<0.01; mRNA: 8.39±0.63 vs 2.45±0.22, P<0.001) inhibited expression of TXNIP (0.15±0.02 vs 0.04±0.01, P<0.01), NLRP3 (1.13±0.12 vs 0.51±0.12, P<0.05) and IL-1ß (1.02±0.04 vs 0.19±0.06, P<0.001) during H/R. Meanwhile, TXNIP exhibited significantly much less colocalization with mitochondria in the si-XBP1+H/R group. Conclusion: Supression of XBP1 expression can effectively alleviate H/R-induced TCMK-1 cells injury, whose mechanism may be inhibition of TXNIP-induced NLRP3 inflammasome activation.

RESUMEN

Objective: To observe the clinical effects of CT-guided chemical destructive block of lumbar sympathetic nerve in the treatment of cold sensation of limbs. Methods: In this retrospective analysis, clinical data of 43 patients with cold sensation of limbs treated by lumbar sympathetic chemical destructive block in the Affiliated Hospital of Jiaxing University from January 2015 to January 2018 were collected. The changes of heart rate, non-invasive blood pressure (NIBP), oxygen saturation (SpO(2)), plantar temperature and peripheral perfusion index (PI) of patients were recorded and analyzed before treatment and 5 min after injection of anhydrous ethanol. The patients were followed up at postoperative 1 day, 1 week, 1 month, 3 months, 6 months, 1 year and 2 years. Results: Fourty-three patients underwent bilateral lumbar sympathetic nerve chemical destructive block under the CT-guided, and all patients were punctured to the target successfully. The PI of patients before and after treatment were 1.2±0.6, 7.2±3.0 respectively, which was significantly increased after treatment compared with before treatment, and the difference was statistically significant (t=12.386, P<0.05). The plantar temperature of patients before and after treatment respectively were (29.6±1.7)℃, (34.6±1.1)℃, which was significantly increased after treatment compared with before treatment, and the difference was statistically significant (t=15.057, P<0.05). There were no significant differences in heart rate, NIBP and SpO(2) between before and after treatment (all P>0.05). Lumbar sympathetic chemical destructive block was clinically effective in 39 patients (90.7%) and ineffective in 4 patients (9.3%). Among the 39 clinically effective patients, the curative effects were excellent in 29 cases and improved in 10 cases. Postoperative recurrence occurred in 10 cases (25.6%). The satisfaction rates of patients at 1 day, 1 week, 1 month, 3 months, 6 months, 1 year and 2 years after operation were 93.0%, 90.7%, 86.0%, 76.7%, 69.7%, 65.1% and 53.4%, respectively. Conclusion: Lumbar sympathetic chemical destructive block is a safe and effective way for the treatment of cold sensation of limbs, which can improve the symptoms of cold sensation of limbs to some extent.

RESUMEN

The single intradermal comparative cervical tuberculin (SICCT) test and post-mortem examination are the main diagnostic tools for bovine tuberculosis (bTB) in cattle in the British Isles. Latent class modelling is often used to estimate the bTB test characteristics due to the absence of a gold standard. However, the reported sensitivity of especially the SICCT test has shown a lot of variation. We applied both the Hui-Walter latent class model under the Bayesian framework and the Bayesian model specified at the animal level, including various risk factors as predictors, to estimate the SICCT test and post-mortem test characteristics. Data were collected from all cattle slaughtered in abattoirs in Northern Ireland in 2015. Both models showed comparable posterior median estimation for the sensitivity of the SICCT test (88.61% and 90.56%, respectively) using standard interpretation and for post-mortem examination (53.65% and 53.79%, respectively). Both models showed almost identical posterior median estimates for the specificity (99.99% vs. 99.80% for SICCT test at standard interpretation and 99.66% vs. 99.86% for post-mortem examination). The animal-level model showed slightly narrower posterior 95% credible intervals. Notably, this study was carried out in slaughtered cattle which may not be representative for the general cattle population.

RESUMEN

Agricultural or food processing wastes cause serious environmental burden and economic losses. Solid-state fermentation using these wastes is an attractive option to valorize these wastes. However, conventional autoclaving of substrate may degrade nutrients and generate toxins. Unsterilization of the substrate will cause undesired microbial contamination. Therefore, we compared irradiation with autoclaving to treat citrus wastes as substrate for solid-state fermentation by Aspergillus aculeatus. By comparing microbial growth, enzymes tested and medium consumption, irradiated substrate had higher biomass and extracellular protein, more sugar consumption and higher enzyme production than those with autoclaved substrate. Irradiation prevented the generation of cell-inhibiting components such as 5-hydroxymethylfurfural (5-HMF) whereas preserved the flavonoids well that are often enzyme inducers. These findings suggest that irradiation of agricultural and food processing wastes as substrate has advantages over autoclaving for solid-state fermentation. SIGNIFICANCE AND IMPACT OF THE STUDY: This study proposes irradiation as an alternative to sterilize agricultural residues rich in nutrients and thermosensitive compounds, such as citrus wastes for fungal solid-state fermentation and production of enzymes.

RESUMEN

This study investigated the effects of different amino acids on the fermentation of pure inulin and glucose using Paenibacillus polymyxa ZJ-9 in order to improve the production of R,R-2,3-butanediol (R,R-2,3-BD) respectively. The inulin extract from Jerusalem artichoke tubers contained 19 common amino acids, which were detected by HPLC. Arg featured the highest content (1290 mg l-1 ). A single add-back experiment of 20 common amino acids indicated that Asn, Ser, His and Arg are key amino acids in R,R-2,3-BD synthesis during inulin fermentation using P. polymyxa ZJ-9. The corresponding yields of R,R-2,3-BD reached 24·32, 22·32, 22·03 and 21·04 g l-1 after the four key amino acids (1·5 g l-1 each) and glucose were evaluated in this fermentation. The yields were considerably higher than that of the control group (12·11 g l-1 ). With the addition of the mixture of four amino acids (1·5 g l-1 each), the highest yields of R,R-2,3-BD (25·07 and 17·47 g l-1 ) were obtained with the increase of 107·0 and 89·1% during the fermentation of glucose and pure inulin respectively. SIGNIFICANCE AND IMPACT OF THE STUDY: Paenibacillus polymyxa is a micro-organism with a reported potential for industrialized production of R,R-2,3-butanediol. The nitrogen sources have a significant effect on R,R-2,3-butanediol formation using P. polymyxa. This study demonstrated a highly efficient new method to improve the yield of R,R-2,3-butanediol without adding other nitrogen sources except amino acids during the fermentation. This will therefore decrease the production cost of R,R-2,3-butanediol and provide a new strategy for promoting synthesis of amino acid-dependent products.

RESUMEN

Objective: To analyze the indication and the outcome of trans-sphenoidal surgery (TSS) in Cushing's disease (CD) with negative high dose dexamethasone suppression tests (HDDST) results. Methods: Eighteen cases of ACTH-dependent Cushing's syndrome (CS) with negative HDDST results in the Department of Neurosurgery in Shanghai Ruijin Hospital from January 2015 to December 2017 were retrospectively reviewed. All patients underwent TSS. There were 5 males and 13 females, with an average age of (41±14) years. Results: All patients underwent bilateral inferior petrosal sinus sampling (BIPSS) before the surgery and got evidence of pituitary origin of ACTH secretion. They were thus indicated for TSS. Immediate post-operative remission was achieved in ratio 17/18. There were no recurrences within a flow-up of 1 to 3 years. Pituitary ACTH secreting adenomas were pathologically confirmed in 15 cases, including the one who did not achieve post-operative remission. Thus, all 18 patients with negative HDDST results can finally be confirmed as CD. Conclusions: HDDST alone is not sufficient to eliminate CD. For patients with ACTH-dependent CS with negative HDDST results, BIPSS should be further performed. The fact of post-operative remission and the pathological confirm of ACTH secreting pituitary adenoma may add final evidence to the diagnosis of CD.

RESUMEN

Objective: To investigate the effects of ultrasound-guided lateral and medial point blocks of thoracic paravertebral space on the rapid recovery of laparoscopic cholecystectomy. Methods: A total of 90 patients of either sex, aged 18-67 years, weighted 45.10-91.80 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, undergoing elective laparoscopic cholecystectomy were divided into two groups (n=45) using a random number table: lateral point group of thoracic paravertebral space (group A) and medial point group of thoracic paravertebral space (group B). Ultrasound-guided thoracic paravertebral nerve block was performed before induction of general anesthesia. The puncture point of group A was positioned as the intercostal block of the thoracic paravertebral space of the right side of T(6)-T(11), and the puncture point of the group B was positioned as the thoracic paravertebral body of the right side of T(6)-T(11) thoracic paravertebral space. The thoracic paravertebral block was performed with 2 ml of 0.75% ropivacaine per injection for a total of 10 ml. The visual analog scale (VAS) scores of resting pain and active pain at 4, 8, 12 and 24 h after operation were observed. The anus recovery time after surgery and perioperative hypotension were also recorded. Results: The blood pressures in group A were significantly higher than those in group B at 4, 8, 12 and 24 h after operation, which were(73±7) vs (70±7), (78±7) vs (74±7),(82±7) vs (79±7),and (87±7) vs (83±7) mmHg,and the differences were statistically significant (t=2.29, 2.54, 2.33, 2.37, all P<0.05). The VAS scores of resting pain and active pain in group A were significantly higher than those in group B, and the differences were statistically significant (Z=-2.29, -2.51, -2.21, -2.39, -2.53, -2.25, -2.30, -2.24, all P<0.05). The postoperative anal exhaust recovery time of the patients in group A was (21.8±1.9) min that was obvious lower than that in group B which was (22.7±1.9) min with statistically significant difference (t=2.12, P<0.05). There was no significant difference in the incidence of postoperative dizziness, nausea, vomiting, and pruritus (χ(2)=0.28, 0.72, 0.45, 0.21,all P>0.05). Conclusions: In the procedure of thoracic paravertebral block under the guidance of ultrasound, the closer blocking points are to the central axis of the spine, the better the postoperative analgesic effect, but the more obvious the postoperative blood pressure reduction and the longer the anal recovery exhaust time. The further away from the central axis of the spine, the more analgesic effect decreases, but the blood pressure decreases and the anal recovery time is relatively rapid.

RESUMEN

Objective: To investigate the change and relationship between serum high-mobility group box-1(HMGB1) and related inflammatory cytokines level in patients suffer with bone metastatic pain. Methods: Collection of the bone cancer pain patients who received analgesic therapy the department of pain in The First Affiliated Hospital of Jiaxing University from November 2016 to August 2016. Serum concentration of HMGB1, the Receptor of Advanced Glycation Endproducts (RAGE), monocyte chemotactic protein-1(MCP-1), tumor necrosis factor -α (TNF-α), interleukin-1ß (IL-1ß), interleukin-10 (IL-10), interleukin-13 (IL-13), and transforming growth factor-ß (TGF-ß) levels were determined in 15 healthy individuals as healthy donor and 15 patients with bone metastatic pain by enzyme-linked immunosorbent (ELISA) . The healthy individuals and patients with bone metastatic pain were collected before treatment and on 7 d after the treatment. Results: The serum concentration of HMGB1 and RAGE were significantly increased in tumorous group compared with healthy group[(8.8±2.3) vs (1.9±1.1) µg/L,(231±16) vs (46±20) ng/L); t=7.10,12.44, both P<0.05], then decreased after analgesic therapy [(4.77±1.36) µg/L, (129.80±29.32) ng/L, t=7.10, 12.44, both P<0.05]. The serum concentration of proinflammatory cytokines such as MCP-1, TNF-α, and IL-1ß were significantly increased in tumorous group when compared with healthy group, and decreased after analgesic therapy (all P<0.05). The expression of anti-inflammatory cytokines such as IL-10, IL-13, and TGF-ß were significantly increased in tumorous group when compared with healthy group, and decreased after analgesic therapy (all P<0.05).Compared with healthy group, the levels of MCP-1/IL-10, MCP-1/IL-13, MCP-1/TGF-ß, TNF-α/IL-10, TNF-α/IL-13, TNF-α/TGF-ß, IL-1ß/IL-10, IL-1ß/IL-13, IL-1ß/TGF-ß were significantly increased in tumorous group (all P<0.05). Conclusion: HMGB1 may adjust the proinflammatory-anti-inflammatory system homeostasis to participate in the development of bone metastatic pain.

RESUMEN

Immune thrombocytopenia (ITP) is an autoimmune bleeding disorder characterized by increased peripheral immune platelet destruction and megakaryocyte defects in the bone marrow. Although ITP was originally thought to be primarily due to antibody-mediated autoimmunity, it is now clear that T cells also play a significant role in the disease. However, the exact interplay between platelet destruction, megakaryocyte dysfunction and the elements of both humoral and cell-mediated immunity in ITP remains incompletely defined. While most studies have focused on immune platelet destruction in the spleen, an additional possibility is that the antiplatelet antibodies can also destroy bone marrow megakaryocytes. To address this, we negated the effects of T cells by utilizing an in vivo passive ITP model where BALB/c mice were administered various anti-αIIb, anti-ß3 or anti-GPIb antibodies or antisera and platelet counts and bone marrow megakaryocytes were enumerated. Our results show that after 24 hours, all the different antiplatelet antibodies/sera induced variable degrees of thrombocytopenia in recipient mice. Compared with naïve control mice, however, histological examination of the bone marrow revealed that only 2 antibody preparations (mouse-anti-mouse ß3 sera and an anti- αIIb monoclonal antibody (MWReg30) could affect bone marrow megakaryocyte counts. Our study shows that while most antiplatelet antibodies induce acute thrombocytopenia, the majority of them do not affect the number of megakaryocytes in the bone marrow. This suggests that other mechanisms may be responsible for megakaryocyte abnormalities seen during immune thrombocytopenia.

RESUMEN

AIM: To evaluate the correlation between miRNA-375 and cell proliferation and apoptosis in glioma cancer cell. METHODS: Collecting 30 cases of glioma cancer patients and 30 cases of cerebral infarction patients. The miRNA-375 and CTGF protein expressions were evaluated by ISH and IHC methods. In the cell experiment, the U87 cells were divided into 3 groups: NC group (the cells were treated with normal method); BL group (the cells were transfected with empty vector) and miRNA group (the cells were transfected with miRNA-375). The U87 cell proliferation and apoptosis rates and cell cycle of the different groups were measured by MTT and flow cytometry. The relative proteins (CTGF, EGFR, AKT, Erk and P21) expressions were measured by WB assay. RESULTS: The miRNA-375 and CTGF expressions of glioma cancer tissues were significantly different compared with those of no-cancer tissues (p < 0.05, respectively). In the cell experiments, the cell proliferation of miRNA group was significantly decreased compared with that of NC group (p < 0.05); the cell apoptosis and G1 phase rate of miRNA group was significantly decreased compared with NC group (p < 0.05, respectively). Depending on the WB assay, the CTGF, EGFR, AKT, Erk and P21 proteins expressions of miRNA group were significantly different compared with proteins expressions of NC group (p < 0.05, respectively). CONCLUSION: miRNA-375 over-expression suppresses glioma cancer cells development via CTGF-EGFR pathway (Fig. 3, Ref. 30).

RESUMEN

Objective: To investigate the clinicopathological, and molecular characteristics of myoepithelial tumors (MTs) of salivary glands. Methods: A total of 37 MTs cases including 13 malignant epithelial tumors (MMTs) and 24 benign epithelial tumors (BMTs) of salivary glands were identified from the archives of the Department of Pathology, General Hospital of Eastern Theater Command, dating from 2006 to 2016. Clinical features, histological patterns, immunohistochemical characteristics and status of EWSR1 gene rearrangement by fluorescence in situ hybridization (FISH) analysis were reviewed in all cases. Results: Clinically, 37 MTs cases mainly occurred in the parotid glands, when most of the patients presented with painless masses. Of the 13 MMTs cases, male to female ratio was 7∶6, and the median age was 62 years old. Of the 24 BMTs cases, male to female ratio was 5∶7, and the median age was 54 years old. Immunohistochemically, 37 MTs cases were positive for CKpan, and at least one myoepithelial marker. Twenty six of 37 MTs cases were analyzable for the EWSR1 gene break by FISH. Based on the previous evaluation criterion, the EWSR1 translocation was detected in 4 cases of 11 MMTs, and 4 cases of 15 BMTs. According to the main histological composition of tumor cells, 4 EWSR1-positive MMTs covered 2 clear-cell cases and 2 epithelioid-cell cases, when 4 EWSR1-positive BMTs covered 2 clear-cell cases, 1 plasmacytoid-cell case, and 1 spindle-cell case. Conclusions: Males and females are affected equally. MTs express immunoreactivity for CKpan, and at least one myoepithelial marker. The EWSR1 rearrangement is present in a subset of MTs, with variable morphological characteristics, and has no statistical significance on clinical behavior.

RESUMEN

AIMS: The cell-surface display of chitinase Chi9602ΔSP was constructed on Bacillus thuringiensis BMB171 by using two repeat N-terminal regions of autolysin (Mbgn)2 as the anchoring motif. This study aimed to prepare a chitinolytic whole-cell B. thuringiensis biocatalyst with improved catalytic and antifungal activities. METHODS AND RESULTS: The chitinase Chi9602ΔSP was displayed on the cell surface of B. thuringiensis BMB171 by using (Mbgn)2 as the anchoring motif. Immunofluorescence microscopic assays and flow cytometry confirmed that Chi9602ΔSP was anchored onto the surface of vegetative cells and spores. Western blot analysis further confirmed that the (Mbgn)2 -Chi9602ΔSP fusion protein was of the predicted molecular size of 94·2 kDa. A whole-cell-specific chitinase activity assay demonstrated that catalytic activities towards colloidal chitin of the recombinant strain (MB333) were significantly improved compared with those of wild inactive B. thuringiensis BMB171. The pH tolerance, thermostability and ultraviolet (UV) radiation resistance of Chi9602ΔSP also slightly improved compared with the unanchored Chi9602ΔSP displayed on the surface of MB333 cells and cultured for 24 h. After continuous culturing for 120 h, MB333 chitinase activity showed narrow pH tolerance and slightly decreased thermostability. In contrast, the UV radiation resistance capacity was obviously enhanced. An antifungal assay indicated that the recombinant strain exhibited a high inhibitory effect towards the mycelial growth of two phytopathogenic fungi, Fusarium oxysporum FB012 and Physalospora piricola FB016. CONCLUSIONS: We successfully developed a cell-surface display system for Chi9602ΔSP on the surface of B. thuringiensis BMB171. The cell-surface display system can enhance the stability of Chi9602ΔSP and has the potential of becoming a whole-cell biocatalyst for agricultural applications. SIGNIFICANCE AND IMPACT OF THE STUDY: Results demonstrated that the bacterial cell display system can be used to express biocontrol agents on the cell surface of B. thuringiensis and provides an attractive method for inhibiting phytopathogenic fungi.
