Hematochezia due to rectal invasion by an internal iliac artery aneurysm: A case report.

BACKGROUND: This case report presents the rare occurrence of hematochezia due to an internal iliac artery aneurysm leading to an arterioenteric fistula, expanding the differential diagnosis for gastrointestinal bleeding. It emphasizes the importance of considering vascular origins in cases of atypical hematochezia, particularly in the absence of common gastrointestinal causes, and highlights the role of imaging and multidisciplinary management in diagnosing and treating such unusual presentations. CASE SUMMARY: A 75-year-old man with a history of hypertension presented with 12 d of hematochezia, experiencing bloody stools 7-8 times per day. Initial computed tomography (CT) scans revealed an aneurysmal rupture near the right internal iliac artery with suspected hematoma development. Hemoglobin levels progressively decreased to 7 g/dL. Emergency arterial angiography and iliac artery-covered stent placement were performed, followed by balloon angioplasty. Despite initial stabilization, minor rectal bleeding and abdominal pain persisted, leading to further diagnostic colonoscopy. This identified a neoplasm and potential perforation at the proximal rectum. An exploratory laparotomy confirmed the presence of a hematoma and an aneurysm invading the rectal wall, necessitating partial rectal resection, intestinal anastomosis, and ileostomy. Postoperative recovery was successful, with no further bleeding incidents and normal follow-up CT and colonoscopy results after six months. CONCLUSION: In cases of unusual gastrointestinal bleeding, it is necessary to consider vascular causes for effective diagnosis and intervention.

Effect of Enhanced Recovery after Surgery (ERAS) Concept and Cluster Nursing on Psychological State and Pain of Oral Outpatients Undergoing Root Canal Therapy.

Objective: The effect of the concept of enhanced recovery after surgery (ERAS) and pain of patients undergoing root canal therapy in oral clinic. Methods: 200 participants in an oral clinic from March 2020 to March 2022 were enrolled in our study. The control group (n = 100) accepted ERAS-based care and the research group (n = 100) accepted ERAS concept and cluster nursing. Nursing satisfaction, comfort, self-efficacy, subjective well-being, self-rating anxiety scale (SAS), and self-rating depression scale (SDS) scores were compared. Results: The research group had 100% satisfaction rate; the control group had 87% satisfaction rate. After nursing, the scores of comforts and self-efficacy of the two groups increased and the scores of comforts and self-efficacy of the research group were higher than those of the control group. After nursing, the scores of subjective well-being of the two groups increased. Furthermore, the higher scores of life satisfaction, interpersonal harmony, and self-efficacy in the research group were found. There was no significant difference in the scores of SAS and SDS between the two groups before nursing (P > 0.05), but after nursing, the scores of SAS and SDS in the two groups decreased, and the scores of SAS and SDS in the research group were lower than those in the control group, and there are statistically significant differences between the groups (P < 0.05). The scores of visual analogue score (VAS) and numerical rating scale (NRS) following intervention decreased, and there are statistically significant differences between the groups (P < 0.05). The less physiological, psychological, social functions, and health self-cognition in the research group were displayed, and there are statistically significant differences between groups (P < 0.05). Conclusion: The adoption of the concept of ERAS and cluster nursing can effectively improve the psychological state and pain score of oral outpatients undergoing root canal therapy, improve comfort and self-efficacy, and enhance subjective well-being and quality of life. ERAS and cluster nursing is of great significance in relieving pain after root canal therapy in the outpatient department, reducing patients' pain and improving patients' quality of life.

The Psychological Nursing Interventions Based on Pygmalion Effect Could Alleviate Negative Emotions of Patients with Suspected COVID-19 Patients: a Retrospective Analysis.

PURPOSE: This study aims to explore the psychological status of suspected COVID-19 patients during quarantine and put forward a new yet effective psychological nursing strategy for intervention. PATIENTS AND METHODS: We performed a retrospective study with suspected COVID-19 patients who were hospitalized to the two hospitals of Hunan province, China and accepted the intervention of psychological nursing from 01/2020 to 03/2020. The control group received routine psychological nursing care and the observation group received the new psychological nursing intervention according to Pygmalion effect. RESULTS: A total of 89 objects were included in the analysis. Results of the questionnaire before intervention showed that the majority of isolated suspected COVID-19 patients showed negative emotions, with the incidence of depression (51.69%), anxiety (14.617%), inverted provocation (22.47%), extraverted provocation (25.84%). And the extraverted provocation scores of female patients was significantly higher than that of male counterparts (P < 0.05). At discharge, compared with the control group, the scores of depression, anxiety, introversion and extraversion of patients in the observation group were significantly lower after nursing intervention based on Pygmalion effect. The satisfaction rate of psychological care based on Pygmalion effect was 86.66%. CONCLUSION: Suspected COVID-19 patients tend to show the symptoms of depression, anxiety and irritation during quarantine. The psychological nursing based on Pygmalion effect is helpful to alleviate their negative emotions.

Panicle Apical Abortion 3 Controls Panicle Development and Seed Size in Rice.

BACKGROUND: In rice, panicle apical abortion is a common phenomenon that usually results in a decreased number of branches and grains per panicle, and consequently a reduced grain yield. A better understanding of the molecular mechanism of panicle abortion is thus critical for maintaining and increasing rice production. RESULTS: We reported a new rice mutant panicle apical abortion 3 (paa3), which exhibited severe abortion of spikelet development on the upper part of the branches as well as decreased grain size over the whole panicle. Using mapping-based clone, the PAA3 was characterized as the LOC_ Os04g56160 gene, encoding an H+-ATPase. The PAA3 was expressed highly in the stem and panicle, and its protein was localized in the plasma membrane. Our data further showed that PAA3 played an important role in maintaining normal panicle development by participating in the removal of reactive oxygen species (ROS) in rice. CONCLUSIONS: Our studies suggested that PAA3 might function to remove ROS, the accumulation of which leads to programmed cell death, and ultimately panicle apical abortion and decreased seed size in the paa3 panicle.

The Oncolytic Virus in Cancer Diagnosis and Treatment.

Cancer has always been an enormous threat to human health and survival. Surgery, radiotherapy, and chemotherapy could improve the survival of cancer patients, but most patients with advanced cancer usually have a poor survival or could not afford the high cost of chemotherapy. The emergence of oncolytic viruses provided a new strategy for us to alleviate or even cure malignant tumors. An oncolytic virus can be described as a genetically engineered or naturally existing virus that can selectively replicate in cancer cells and then kill them without damaging the healthy cells. There have been many kinds of oncolytic viruses, such as herpes simplex virus, adenovirus, and Coxsackievirus. Moreover, they have different clinical applications in cancer treatment. This review focused on the clinical application of oncolytic virus and predicted the prospect by analyzing the advantages and disadvantages of oncolytic virotherapy.

Prediction and identification of immune genes related to the prognosis of patients with colon adenocarcinoma and its mechanisms.

BACKGROUND: Colon adenocarcinoma (COAD) is a gastrointestinal tumor with a high degree of malignancy. Its deterioration process is closely related to the tumor microenvironment, and transcription factors (TF) play a regulatory role in this process. Currently, there is a lack of exploration between the genes related to the COAD tumor microenvironment and the survival prognosis of patients. Models composed of multiple genes usually predict the survival prognosis of patients more accurately than single genes. We can analyze the multigene models that can predict the prognosis of COAD from the current database. METHODS: The limma package of the R programming language is used for gene differential expression analysis. Kaplan-Meier curve is used to analyze the relationship between the patient risk score model and survival data. The hazard model is used to analyze the relationship between the risk score and the clinical data of COAD patients. The information of immune genes and immune cells is obtained from IMMPORT database and TIMER database. Receiver operating characteristic (ROC) curve is used to judge the stability of the model. RESULTS: We found 7 immune genes, which can built a risk score model to predict the survival prognosis of COAD. According to univariate and multivariate analysis, the risk score can be used as an independent predictor. The content of some immune microenvironment cells will also increase as the risk score increases. CONCLUSIONS: We found 7 immune genes, such as SLC10A2 (solute carrier family 10 member 2), CXCL3 (C-X-C motif chemokine ligand 3), IGHV5-51 (immunoglobulin heavy variable 5-51), INHBA (inhibin subunit beta A), STC1 (stanniocalcin 1), UCN (urocortin), and OXTR (oxytocin receptor), can constitute a model for predicting the prognosis of COAD. They may provide potential therapeutic targets for clinical treatment of COAD.

MULTI-FLORET SPIKELET 2, a MYB Transcription Factor, Determines Spikelet Meristem Fate and Floral Organ Identity in Rice.

An understanding of flower and panicle development is crucial for improving yield and quality in majority of grass crops. In this study, we used mapping-based cloning to identify MULTI-FLORET SPIKELET2 (MFS2), which encodes a MYB transcription factor and regulates flower and spikelet development in rice (Oryza sativa). In the mfs2 mutant, specification of palea identity was severely disturbed and showed degradation or transformation into a lemma-like organ, and the number of all floral organs was increased to varying degrees. Due to the increase in the number of floral organs and development of extra transformed palea/marginal region of the palea-like organs, some mfs2 spikelets had a tendency to produce two florets. These defects implied that the mfs2 mutation caused abnormal specification of palea identity and partial loss of spikelet determination. We confirm that MFS2 is a transcriptional repressor that shows strong repression activity by means of two typical ethylene-responsive element binding factor-associated amphiphilic motifs, one of which locates at the C terminus and is capable of interaction with three rice TOPLESS and TOPLESS-related proteins. The results indicate that MFS2 acts as a repressor that regulates floral organ identities and spikelet meristem determinacy in rice by forming a repression complex with rice TOPLESS and TOPLESS-related proteins.

Design and synthesis of potent inhibitors of bc1 complex based on natural product neopeltolide.

Neopeltolide, a natural product isolated from deep-water sponge specimen of the family neopeltidae, has been proven to be a novel inhibitor of cytochrome bc1. In this study, a series of neopeltolide derivatives was designed by replacing the 14-membered macrolactone with indole ring and confirmed by 1H NMR, 13C NMR, and HRMS. Based on the binding mode of 12h with bc1 complex, the IC50 values of compounds 16a-f (ranging from 0.70 to 1.46 µM) were improved significantly than the ester derivatives 12a-u by replacing the ester with amide linker. Subsequently, the molecular docking results indicated that compound 16e could form a π-π interaction with Phe274 and two H-bonds with Glu271 and His161 and the latter H-bond was found to account for its high activity. The present work accelerates the discovery of novel bc1 complex inhibitors to deal with the resistance that the existing bc1 complex inhibitors are facing and provides a valuable idea for the design of new fungicides.

Post ureteroscopic stone surgery ureteral strictures management: a retrospective study.

PURPOSE: To share experience in managing ureteral strictures following ureteroscopic lithotripsy. METHODS: Ninety five patients diagnosed as ureteral strictures after ureteroscopic lithotripsy between January 2013 and January 2018 were included. 53 received endourological treatment, 34 underwent reconstruction, 6 underwent nephrectomy for severe renal impairment, and 2 chose routine ureteral stent replacement. Therapeutic success was defined as absence of clinical symptoms and radiologic relief of obstruction. RESULTS: The follow-up time ranged from 13 to 57 months, with a median time of 24. It lasted more than 13 months in all patients, exception for 2 nephrectomies. Two patient groups including 69 endourological procedures and 37 reconstructions were used to compare therapeutic effects and complications. The overall success rate was 60.9% (42/69) in endourological intervention vs. 97.3% (36/37) in reconstruction (p < 0.001), while 74.4% (29/39) patients with stricture less than 1 cm and 68.8% (33/48) patients with mild-to-moderate hydronephrosis achieved success in endourological group. All except 1 failure appeared within the first year postoperatively. Subgroup analyses for endourological procedures revealed significant differences in the success rate of different stricture lengths and hydronephrosis (p = 0.004 and p = 0.043). Multivariate Cox regression analysis indicated that reconstruction was significantly related to a more successful outcome, compared with endourological procedures (HR 0.052, 95% CI 0.007-0.394, p = 0.004). CONCLUSION: Reconstruction performs better than endourological procedures in surgical outcome. Endourological procedure provides an acceptable success rate in patients with stricture shorter than 1 cm and slight hydronephrosis. Most stricture recurrence appeared within the first year postoperatively.

The average number of interspecific and intraspecific genetic distance of COⅠ ranged from 7.2% to 13.6% and 0.0% to 6.3%, respectively. Conclusion The gene sequences of COⅠ and 16S rDNA can accurately identify the species of different necrophagous flies, and 16S rDNA showed higher value in species identification of common calliphoridae necrophagous flies in Fujian Province.

An Updated Meta-Analysis of the Associations Between MicroRNA Polymorphisms and Susceptibility to Rheumatoid Arthritis.

Aims: Rheumatoid arthritis (RA) is characterized by cartilage and bone damage leading to disability. Here, the association between microRNA (miRNA) polymorphisms and susceptibility to RA was evaluated by performing an updated meta-analysis and systematic review. Main methods: An electronic search of databases including PubMed and Embase was performed from inception to December 8, 2017 to retrieve studies investigating the association between miRNA polymorphisms and RA risk. Two reviewers independently screened literature according to the inclusion and exclusion criteria and extracted data. The meta-analysis was conducted using Stata 14.0 software. Key findings: Thirteen case-control studies with 2660 cases and 4098 controls were screened out after a systematic search. One study from the miR-146a rs2910164 G > C polymorphism group and two from the miR-499 rs3746444 T > C polymorphism group were excluded because of deviations from Hardy-Weinberg equilibrium. Pooled analysis demonstrated that miR-146a rs2910164 G > C polymorphism was not significantly associated with susceptibility to RA. However, a significant association was observed between miR-499 rs3746444 T > C polymorphism and RA risk (C vs. T: OR = 1.22, 95% CI = 1.05-1.42, P = 0.008; TC vs. TT: OR = 1.26, 95% CI = 1.05-1.50, P = 0.011; TC/CC vs. TT: OR = 1.26, 95% CI = 1.07-1.5, P = 0.007). Subgroup analysis based on ethnicity showed no significant association between miR-499 T > C polymorphism and susceptibility to RA in the Asian population (P > 0.05). However, in Caucasian population, the C allele in the miR-499 T > C polymorphism was a contributor to RA susceptibility in some genetic models (C vs. T: OR = 1.64, 95% CI = 1.28-2.11, P < 0.001; TC vs. TT: OR = 1.95, 95% CI = 1.40-2.71, P < 0.001; TC/CC vs. TT: OR = 1.96, 95% CI = 1.43-2.69, P < 0.001). Significance: The miR-146a rs2910164 G > C polymorphism was not associated with susceptibility to RA. In the Caucasian population, the C allele in the miR-499 T > C polymorphism contributed to RA susceptibility.

Association Between TERT rs2736098 Polymorphisms and Cancer Risk-A Meta-Analysis.

Background: Cancer remains a leading cause of death and constitutes an enormous burden on society worldwide. The association between the human telomerase reverse transcriptase (TERT) gene variant rs2736098 polymorphisms and cancer predisposition remain inconclusive. Objective and methods: Databases including Pubmed and Embase were systematically searched from inception to September 15, 2017 to retrieve studies investigating the association between the TERT variant rs2736098 polymorphisms and cancer risk in accordance with previously determined exclusion and inclusion criteria. The pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were evaluated using random or fixed effects models. Results: Thirty-one case-control studies from 29 articles with 15,837 cases and 19,263 controls were screened out after a systematic search. Pooled analysis demonstrated that the TERT variant rs2736098 G > A polymorphism was significantly correlated with cancer risk in all populations (A vs. G: OR = 1.134, 95% CI = 1.051-1.224, P = 0.001; AA vs. GG: OR = 1.280, 95% CI = 1.087-1.508, P = 0.003; GA vs. GG: OR = 1.125, 95% CI = 1.020-1.240, P = 0.018; GA/AA vs. GG: OR = 1.159, 95% CI = 1.047-1.283, P = 0.004). In the subgroup analysis based on cancer type, the TERT rs2736098 with the A allele was 1.299 times more frequent than that with the G allele (OR = 1.299, 95% CI = 1.216-1.386) under the allelic genetic model in lung cancer, and 1.152 times (OR = 1.152, 95% CI = 1.032-1.286) that in bladder cancer. Conclusions: This meta-analysis demonstrated significant correlations between the TERT variant rs2736098 polymorphisms and cancer susceptibility. The A allele in the rs2736098 G > A polymorphism contributes to susceptibility in many types of cancer, especially lung cancer and bladder cancer.

Ultrasound-guided needle release of the transverse carpal ligament with and without corticosteroid injection for the treatment of carpal tunnel syndrome.

BACKGROUND: To compare the clinical effectiveness of ultrasound-guided needle release of the transverse carpal ligament (TCL) with and without corticosteroid injection in carpal tunnel syndrome (CTS). METHODS: From June 2016 to June 2017, 49 CTS patients (50 wrists) were included in this study. Twenty-five wrists were treated with ultrasound-guided needle release of the TCL plus corticosteroid injection (group A), and 25 wrists were treated with single ultrasound-guided needle release of the TCL (group B). The following parameters were assessed and compared including postprocedure results according to relief of symptoms, ultrasound parameters (cross-sectional area of the median nerve at the levels of pisiform, flattening ratio of median nerve at the levels of the hamate bone, and the thicknesses of TCL on the cross-section at the level of the hamate bone), and electrophysiological parameters (distal motor latency and sensory conduction velocity). RESULTS: Group A had higher overall excellent and good rate 3 months after the procedure than group B (84 vs 52%, P < 0.05). There were significant differences regarding the above ultrasonic and electrophysiological parameters between the baseline and postprocedure values in both groups (all P < 0.05). There were significant differences regarding the postprocedure values of above ultrasonic and electrophysiological parameters between the two groups (all P < 0.05). No complications such as infection or tendon rupture were noted. No procedures were converted to the open release. CONCLUSIONS: Both techniques are effective in treating CTS. Ultrasound-guided needle release of the TCL with corticosteroid injection had better treatment benefits than single ultrasound-guided needle release of the TCL in treating CTS.

In†situ Generated Ruthenium Catalyst Systems Bearing Diverse N-Heterocyclic Carbene Precursors for Atom-Economic Amide Synthesis from Alcohols and Amines.

The transition-metal-catalyzed direct synthesis of amides from alcohols and amines is herein demonstrated as a highly environmentally benign and atom-economic process. Among various catalyst systems, in situ generated N-heterocyclic carbene (NHC)-based ruthenium (Ru) halide catalyst systems have been proven to be active for this transformation. However, these existing catalyst systems usually require an additional ligand to achieve satisfactory results. In this work, through extensive screening of a diverse variety of NHC precursors, we discovered an active in situ catalyst system for efficient amide synthesis without any additional ligand. Notably, this catalyst system was found to be insensitive to the electronic effects of the substrates, and various electron-deficient substrates, which were not highly reactive with our previous catalyst systems, could be employed to afford the corresponding amides efficiently. Furthermore, mechanistic investigations were performed to provide a rationale for the high activity of the optimized catalyst system. NMR-scale reactions indicated that the rapid formation of a Ru hydride intermediate (signal at δ=-7.8 ppm in the 1 H NMR spectrum) after the addition of the alcohol substrate should be pivotal in establishing the high catalyst activity. Besides, HRMS analysis provided possible structures of the in situ generated catalyst system.

Positive prognostic value of HER2-HER3 co-expression and p-mTOR in gastric cancer patients.

BACKGROUND: The HER2-HER3 heterodimer significantly decreases survival in breast cancer patients. However, the prognostic value of HER2-HER3 overexpression remains unknown in gastric cancer (GC). METHODS: The expression levels of HER2, HER3, Akt, p-Akt, mTOR and p-mTOR were examined in specimens from 120 GC patients by immunohistochemistry and quantitative reverse transcription-PCR. The associations of HER proteins, PI3K/Akt/mTOR pathway-related proteins, clinicopathological features of GC, and overall survival (OS) were assessed. To comprehensively evaluate the prognostic values of pathway-related proteins, meta-analyses were conducted with STATA 11.0. RESULTS: HER2 overexpression was significantly associated with HER3 levels (P = 0.02). HER3 was highly expressed in gastric cancer tissues. High HER2 and HER3 levels were associated with elevated p-Akt and p-mTOR amounts (P < 0.05). Furthermore, HER2-HER3 co-expression was associated with high p-Akt and p-mTOR (P < 0.05) levels. Meanwhile, p-mTOR overexpression was tightly associated with differentiation, depth of invasion, lymph node metastasis, TNM stage and OS (P < 0.05). By meta-analyses, Akt, p-Akt, and mTOR levels were unrelated to clinicopathological characters. HER3 overexpression was associated with depth of invasion (OR = 2.39, 95%CI 1.62-3.54, P < 0.001) and lymph node metastasis (OR = 2.35, 95%CI 1.34-4.11, P = 0.003). Further, p-mTOR overexpression was associated with patient age, tumor location, depth of invasion (OR = 1.63, 95%CI 1.08-2.45, P = 0.02) and TNM stage (OR = 1.73, 95%CI 1.29-2.32, P < 0.001). In addition, HER2-HER3 overexpression corresponded to gradually shortened 5-year OS (P < 0.05), and significant relationships were shown among HER3, p-mTOR overexpression, and 1-, 3-, 5-year OS (P < 0.05). CONCLUSIONS: HER2-HER3 co-expression may potentially enhance mTOR phosphorylation. HER2-HER3 co-expression and p-mTOR are both related to the prognosis of GC patients.

Ginkgetin inhibits growth of breast carcinoma via regulating MAPKs pathway.

The purpose of present study was to investigate anti-tumor activity of Ginkgetin (GK) and its mechanism of action in breast cancer. The effects of GK on growth of human breast cancer cell lines MDA-MB-231, BT-474 and MCF-7 were examined by MTT assay. Cells apoptosis in MCF-7 cells were analyzed by TUNEL staining and annexin-V and propidium iodide double staining. The effects of GK on expression of apoptotic associated proteins and mitogen-activated protein kinases (MAPKs) were determined by western blotting. The results showed that GK significantly inhibited proliferation of MDA-MB-231, BT-474 and MCF-7 cells in vitro with time and dose dependent manners and induced apoptosis in MCF-7 cells. GK treatment obviously induced the tumor cells apoptosis and inhibited tumor growth in the MCF-7 xenograft nude mice. GK increased expression of Bax, cleaved-caspase-3, cleaved-caspase-8, cleaved-caspase-9, cleaved-PARP, and decreased the levels of Bcl-2 and survivin in MCF-7 cells. Moreover, GK treatment up-regulated expression of phospho extracellular-related kinase (p-ERK), p-p38 and phospho Jun-amino-terminal kinase (p-JNK) in MCF-7 cells in vitro, and increased numbers of p-p38, p-JNK and p-ERK positive cells in the tumor tissue in vivo. Strikingly, treatment of p38 inhibitor (or JNK inhibitor; ERK inhibitor) significantly prevented GK induced growth inhibition and apoptosis in MCF-7 cells. Collectively, our data exhibit GK exerts well anticancer effects in breast cancer cells, which at least in part, is via activation of the MAPKs. Our results provide a new approach for the treatment of breast cancer.

Role of metastasis-associated protein 1 in prognosis of patients with digestive tract cancers: A meta-analysis.

OBJECTIVES: Metastasis-associated protein 1 (MTA1) is a transcriptional regulator and significantly associated with prognosis of patients with cancer. However, its role as a potential prognostic marker in digestive tract cancer (DTC) is controversial. In this study, a meta-analysis was conducted to evaluate the MTA1 expression as a predictor of clinicopathology and survival of patients with DTC. METHODS: We searched PubMed, Ovid, Web of Science and Cochrane databases using multiple search strategies for eligible studies. STATA 11.0 software was used to pool the data and analyze the association, odds ratios (ORs) and 95% confidence intervals (CIs) were used to measure the strength of the association. Furthermore, the Newcastle-Ottawa scale was used to evaluate the quality of eligible studies. RESULTS: MTA1 overexpression was strongly associated with depth of invasion (OR = 1.88, 95%CI: 1.05-3.37, P = 0.03), lymph node metastasis (OR = 2.30, 95%CI: 1.76-3.01, P<0.001), vascular invasion (OR = 2.02, 95%CI: 1.40-2.91, P<0.001) and TNM stage (OR = 2.78, 95%CI: 1.63-4.74, P<0.001), and was related to 1- (RR = 1.84, 95%CI: 1.18-2.89, P = 0.008), 3- (RR = 1.74, 95%CI: 1.32-2.30, P<0.001) and 5-year (RR = 1.64, 95%CI: 1.18-2.27, P = 0.003) OS. Further, MTA1 was associated with 1- (RR = 4.16, 95%CI: 1.35-12.81, P = 0.01), 3- (RR = 1.90, 95%CI: 1.02-3.53, P = 0.04) and 5- (RR = 2.17, 95%CI: 1.41-3.32, P<0.001) year DFS. In subgroup analyses based on study quality and tumor type, MTA1 overexpression was obviously related to clinical parameters, such as lymph node metastasis and TNM stage, and was also associated with prognosis of patients with gastrointestinal or esophageal cancer. CONCLUSIONS: MTA1 expression is strongly correlated with metastasis-related variables, and represents a promising prognostic factor in DTC.

Comparison of the Clinical Effectiveness of Ultrasound-Guided Corticosteroid Injection with and without Needle Release of the Transverse Carpal Ligament in Carpal Tunnel Syndrome.

BACKGROUND: To compare the clinical effectiveness of ultrasound-guided corticosteroid injection with and without needle release of the transverse carpal ligament (TCL) in carpal tunnel syndrome (CTS). METHODS: Between May 2014 and June 2016, 52 patients (56 wrists) with CTS were included in this study. Among these patients, 28 wrists were treated with ultrasound-guided corticosteroid injection plus needle release of the TCL (group A) and 28 wrists were treated with a single ultrasound-guided corticosteroids injection (group B). The following parameters were assessed and compared including postoperative results of procedure based on relief of symptoms, electrophysiological parameters (distal motor latency, sensory conduction velocity, and sensory nerve action potential of median nerve), and ultrasound parameters (anteroposterior diameter and cross-sectional area of the median nerve at the levels of pisiform and hamate bone, and the thicknesses of TCL on the cross-section at the level of hamate bone). RESULTS: The overall excellent and good rate regarding the postoperative results of procedure based on the relief of symptoms at 1 month postoperatively was 82.1% in group A and 46.4% in group B (p = 0.004). There was significant difference in the above electrophysiological and ultrasound parameters between the preoperative and postoperative values in both groups (all p < 0.05). Furthermore, a significant difference was also observed in the postoperative values of the above-mentioned electrophysiological and ultrasound parameters in the 2 groups (all p < 0.05). CONCLUSIONS: Both approaches had treatment benefit in CTS. Ultrasound-guided corticosteroid injection in combination with needle release of the TCL is superior to the single ultrasound-guided corticosteroids injection.

Objective Few studies are reported on the relationship of subclinical hypothyroidism ( SCHT ) with visfatin and endothelin .This study aimed to investigate their relationship in patients with cerebral infarction . Methods A total of 200 cerebral in-farction patients treated in The Second Affiliated Hospital of Hainan Medical University from January 2011 to July 2017 were divided in-to a control ( with normal thyroid function , n=40 ) , a mild SCHT ( with thyroid-stimulating hormone TSH <10 mIU/L, normal free triiodothyronine FT3 and normal free thyroxine FT4, n=60), a se-vere SCHT (with TSH≥10 mIU/L, normal FT3 and normal FT4, n=60) , and a clinical hypothyroidism ( CHT ) group ( with TSH ≥4 mIU/L, decreased FT3 and decreased FT4, n=40).The mild SCHT patients were subdivided into medication group A and non-medication group A, and the severe SCHT patients into medication group B and non-medication group B, 30 in each group, those in the medica-tion groups A and B treated by routine therapy plus oral levothyrocine , and those in the non-medication groups A and B by routine ther-apy only.We recorded the age, gender, body mass index, blood pressure, blood glucose, blood lipid, and thyroid function of the pa-tients, and compared the levels of visfatin and endothelin among different groups . Results The level of visfatin was significantly ele-vated in the severe SCHT and CHT groups as compared with the controls ([46.3±10.1] and [49.5±13.6] vs [40.2±9.7] ng/mL, P<0.05), and so was it in medication group B as compared with non-medication group B at 6 months after treatment ([42.9±6.4] vs [39.3±5.5] ng/mL, P<0.05). Conclusion Visfatin is closely related with thyroid hormone in cerebral infarction patients with se -vere subclinical hypothyroidism .Examination of thyroid function is necessary for cerebral infarction patients for the sake of early detec -tion of severe subclinical hypothyroidism and timely intervention .
