RESUMEN

Malignant pleural effusion (MPE) is one of the common complications of lung cancer. The quality of life and prognoses for MPE patients are significantly compromised. Controlling the production of MPE can relieve patients' symptoms, improve their quality of life, and prolong their survival. This article presents a case of advanced non-small cell lung cancer (NSCLC) with MPE and negative driver genes. The patient received envafolimab and Endostar in combination, resulting in a complete reduction of MPE and durable clinical benefits. The exploratory use of this treatment method improved the quality of life of this patient and has the potential to prolong the survival of this patient.

RESUMEN

The clinical significance of plasma soluble programmed cell death ligand 1 (sPD-L1) and vascular endothelial growth factor (VEGF) for non-small cell lung cancer (NSCLC) treated with the combination of anti-angiogenic therapy and anti-PD-L1 antibody (Ab) remain unknown. This study aimed to explore the association between plasma sPD-L1 and VEGF levels and the prognosis of NSCLC patients treated with the combination of Envafolimab and Endostar. Peripheral blood samples were collected from 24 NSCLC patients at baseline and after 6 weeks of treatment and were detected for sPD-L1 and VEGF levels. Both baseline and posttreatment sPD-L1 were significantly higher in progressive disease (PD) group than in controlled disease (CD) group (median: 77.5 pg/ml vs. 64.6 pg/ml, P  = 0.036, median: 8451 pg/ml vs. 5563 pg/ml, P  = 0.012). In multivariate analysis, lower baseline sPD-L1 levels were significantly associated with longer progression-free survival (PFS) (HR = 6.834, 95% CI: 1.350-34.592, P  = 0.020). There were significantly higher posttreatment VEGF levels in PD group compared with CD group (median: 323.7 pg/ml vs. 178.5 pg/ml, P  = 0.009). Higher posttreatment VEGF levels were significantly associated with shorter PFS in multivariate analysis (HR = 5.911, 95% CI: 1.391-25.122, P  = 0.016). Plasma sPD-L1 and VEGF levels are associated with the clinical response and prognosis of NSCLC patients treated with the combination of PD-L1 inhibitors and anti-angiogenetic therapy.

RESUMEN

Numerous studies have demonstrated that regulatory T (Treg) cells play an important role in the tumour microenvironment (TME). The aim of this study was to investigate whether VEGFR2 affects the expression of miR-3200-3p in exosomes secreted by tumour cells, thereby influencing Treg senescence in the TME. The results showed that VEGFR2 expression level was the highest in Calu-1 cells, and after transfection with si-VEGFR2, the exosomes secreted from Calu-1 cells were extracted and characterised with no significant difference from the exosomes of the untransfected group, but the expression of miR-3200-3p in the exosomes of the transfected si-VEGFR2 group was elevated. The Cell Counting Kit-8 (CCK-8) and flow cytometry (FCM) results suggested that exosomes highly expressing miR-3200-3p could inhibit Treg cell viability and promote apoptosis levels when treated with Treg cells. Detection of the senescence-associated proteins p16 INK4A and MMP3 by western blot (WB) revealed that exosomes highly expressing miR-3200-3p were able to elevate their protein expression levels. Tumour xenograft experiments demonstrated that exosomes with high miR-3200-3p expression promoted Treg cell senescence and inhibited subcutaneous tumour growth in nude mice. Dual-luciferase reporter assays and RNA pull-down assays showed that miR-3200-3p could be linked with DDB1. Overexpression of DDB1 reverses changes in DCAF1/GSTP1/ROS protein expression caused by exosomes with high miR-3200-3p expression. In conclusion, inhibition of VEGFR2 expression in tumour cells promotes the expression of miR-3200-3p in exosomes secreted by tumour cells. miR-3200-3p enters the TME through exosomes and acts on DDB1 in Treg cells to promote senescence of Treg cells to inhibit tumour progression.

RESUMEN

The transcriptomes of Agasicles hygrophila eggs and first instar larvae were analyzed to explore the olfactory mechanism of larval behavior. The analysis resulted in 135,359 unigenes and the identification of 38 odorant-binding proteins (OBPs), including 23 Minus-C OBPs, 8 Plus-C OBPs, and 7 Classic OBPs. Further analysis of differentially expressed genes (DEGs) revealed 10 DEG OBPs, with 5 (AhygOBP5, AhygOBP9, AhygOBP12, AhygOBP15 and AhygOBP36) up-regulated in first instar larvae. Verification of expression patterns of these 5 AhygOBPs using qPCR showed that AhygOBP9 and AhygOBP36 were mainly expressed in the adult stage with gradually increasing expression in the larval stage. AhygOBP5, AhygOBP12, and AhygOBP15 were not expressed in eggs and pupae, and their expression in larvae and adults showed no clear pattern. These 5 AhygOBPs may play an olfactory role in larval behavior, providing a basis for further investigation of their specific functions and clarifying the olfactory mechanism of A. hygrophila.

RESUMEN

Background: In recent years, papillary thyroid carcinoma is considered to be one of the fastest increaseing cancer. NDRG family member 3 (NDRG3) has been proposed as a molecular marker of tumor, and is expected to be used in clinic. Methods: Enzyme-linked immunosorbent assay was used to detect the serum NDRG3 expression in 81 papillary thyroid carcinoma cases, 75 benign thyroid nodules cases and 77 healthy control cases, respectively. Electrochemiluminescence method was applied to measure the levels of triiodothyronine, tetraiodothyronine, thyrotropin, thyroglobulin antibody and thyroid peroxidase antibody. Immunohistochemical staining was used to detect the expression of NDRG3 in papillary thyroid carcinoma, benign thyroid nodules and normal tissues adjacent to cancer. Results: The expression of serum triiodothyronine, tetraiodothyronine, thyrotropin, thyroglobulin antibody and thyroid peroxidase antibody and NDRG3 were significantly different among benign thyroid nodules, papillary thyroid carcinoma cases and healthy control groups (P <0.001). Only the expression of serum NDRG3 was significantly different between benign thyroid nodules and papillary thyroid carcinoma groups (P <0.001). Immunohistochemistry showed that NDRG3 was expressed in all three groups, the lowest in papillary thyroid carcinoma, the second in benign thyroid nodules, and the highest in normal tissues adjacent to cancer. Logistic regression analysis showed that serum NDRG3 was an independent protective factor for papillary thyroid carcinoma (OR =0.964, 95%CI =0.953 to 0.974, P <0.001). The ROC curve of non-papillary thyroid carcinoma diagnosed by serum NDRG3 showed the optimal cut-off value of 481.38 pg/ml, sensitivity of 72.4%, specificity of 90.1%, and the maximum area under the curve (AUC =0.902, 95%CI =0.863 to 0.940, P <0.001). The ROC curve of benign thyroid nodules diagnosed by serum NDRG3 showed the optimal critical value of 459.28 pg/ml, sensitivity of 81.3%, and specificity of 74.1% (AUC =0.863, 95%CI =0.808 to 0.919, P <0.001). The expression level of serum NDRG3 was significantly correlated with extrathyroid extensionand (P =0.007) and lymphatic metastasis of papillary thyroid carcinoma (P =0.019). Conclusions: The decrease of NDRG3 expression can not only differential diagnosis benign thyroid nodules and papillary thyroid carcinoma, but also serve as a molecular marker for the diagnosis of papillary thyroid carcinoma.

RESUMEN

BACKGROUND: Migraine has a great impact on public health. Current acute therapies do not satisfy all migraineurs. The novel serotonin 5-HT1F receptor agonist appears more promising for aborting migraine attacks. OBJECTIVE: To evaluate the clinical efficacy and safety of lasmiditan in treating acute migraine attacks. METHODS: The literature search was performed in PubMed, Embase, and the Cochrane Central Register of Controlled Trials for randomized controlled trials (RCTs) which assessed the effect and safety of lasmiditan on migraine. The risk of bias was assessed using the Cochrane Collaboration's risk of bias tool. Results were extracted and pooled as risk ratios (RRs) with a fixed or random-effects model. RESULTS: Based on the four included RCTs, pooled estimates showed that lasmiditan with the 50 mg, 100 mg, and 200 mg doses was superior to placebo at 2 h after the first dose in terms of pain freedom, absence of migraine-associated symptoms, headache relief, no/mild disability, and global impression of change (very much/much better) (RRs ranged from 1.13 to 1.96), except for nausea-free and vomiting-free. Both lasmiditan 100 mg and 200 mg resulted in significantly fewer patients using rescue medication (100 mg: RR = 0.75, 95% CI (0.61, 0.92), P = 0.007; 200 mg: RR = 0.81, 95% CI (0.66, 0.99), P = 0.04) at 2-24 h postdose, compared with placebo. Safety data showed that the proportion of patients reporting at least one treatment-emergent adverse event (TEAE) and the incidence of most common TEAEs such as dizziness, paresthesia, fatigue, somnolence, and nausea was higher in the lasmiditan groups (50 mg, 100 mg, and 200 mg), compared with placebo. There was no significant difference between lasmiditan and placebo in terms of cardiovascular-related TEAEs (RR = 2.75, 95% CI (0.81, 9.37), P = 0.11). Compared with lasmiditan 100 mg, lasmiditan 200 mg was more effective in pain freedom at 2 h after the first dose (RR = 0.83, 95% CI (0.74, 0.94), P = 0.004) but associated with a higher risk of reporting at least one TEAE (RR = 0.88, 95% CI (0.81, 0.96), P = 0.006). CONCLUSIONS: Lasmiditan with the 50 mg, 100 mg, and 200 mg doses are effective and safe in acute migraine treatment. Lasmiditan 200 mg is more effective than lasmiditan 100 mg in pain freedom, while lasmiditan 100 mg is better tolerated in the short-term follow-up. Further larger sample-size RCTs are required to verify the applicability and tolerability in the long term.

RESUMEN

Cyclooxygenase-2 (COX-2) is known to be involved in the pathogenesis of migraine, and some polymorphisms are known to affect the expression of COX-2. This retrospective case-control study aimed to explore the associations between the -765 G>C (rs20417), -1759 G>A (rs3218625), and -8473 C>T (rs5275) COX-2 polymorphisms and migraine in Chinese Han individuals. One hundred and ten unrelated Han Chinese patients with migraine and 108 healthy controls were recruited between 03/2014 and 08/2016 at the First Affiliated Hospital of Nanjing Medical University and the First People's Hospital of Lianyungang City. The genotypes of all polymorphisms in controls followed the Hardy-Weinberg equilibrium (P = 0.215, P = 0.884, and P = 0.689). There were differences in the genotype and allele distributions of the COX-2-1759G>A (Gly587Arg) polymorphism between the migraine and control groups (P = 0.038 and P = 0.040, respectively). Compared with the COX-2-1759AG genotype, GG genotype carriers had an increased risk of migraine (odds ratio (OR) = 8.720, 95% confidence interval (CI): 1.072-70.960, P = 0.038). The frequency of the COX-2-1759A allele in patients with migraine was significantly lower than the controls (OR = 0.119, 95%CI: 0.015-0.957, P = 0.040). Adjusted age and sex, a statistical difference was found in the dominant model of COX-2-1759 G>A (OR = 0.118, 95% CI 0.014 to 0.962, P = 0.046). No significant difference was detected regarding the -765G>C and -8473T>C polymorphisms between the two groups. The COX-2 1759A allele might be involved in the development of migraine in Chinese Han individuals, but this will have to be confirmed in large-scale studies.

RESUMEN

BACKGROUND: Chronic tinnitus affects approximately 10-15% of the population. Low-frequency repetitive transcranial magnetic stimulation (rTMS) has been considered as a promising and well-tolerated therapeutic strategy for chronic tinnitus. However, a recent large-scale multicenter clinical trial showed a negative result. OBJECTIVE: This systematic review is aimed at assessing the efficacy and safety of low-frequency rTMS in chronic tinnitus. METHODS: We searched PubMed, Embase, and Cochrane Library for randomized controlled studies of rTMS treatment of chronic tinnitus. A pooled analysis of standardized mean difference (SMD) was performed with 95% confidence intervals (CI). RESULTS: Ten RCTs involving 567 participants were included in this review. Compared with sham stimulation, rTMS showed no significant efficacy in tinnitus severity and disability measured by Tinnitus Handicap Inventory (THI) in short-term (SMD = -0.04, 95% CI -0.23 to 0.16, P = 0.72), medium-term (SMD = -0.13, 95% CI -0.43 to 0.17, P = 0.41), and long-term (SMD = -0.16, 95% CI -0.38 to 0.05, P = 0.14) follow-up. Tinnitus severity and disability measured by Tinnitus Questionnaire (TQ) also showed no significant improvement in short-term (SMD = -0.11, 95% CI -0.31 to 0.10, P = 0.30), medium-term (SMD = -0.10, 95% CI -0.37 to 0.16, P = 0.44), and long-term (SMD = -0.20, 95% CI -0.40 to 0.01, P = 0.06) follow-up. Additionally, no statistically significant difference was shown in the changes of tinnitus loudness assessed by a visual analogue scale (VAS) between rTMS and sham groups in the short-term (SMD = -0.28, 95% CI -0.59 to 0.02, P = 0.07), medium-term (SMD = -0.26, 95% CI -0.59 to 0.07, P = 0.13), and long-term (SMD = -0.20, 95% CI -0.53 to 0.13, P = 0.24) follow-up. Few mild or moderate adverse events were observed in both the rTMS and sham groups. CONCLUSION: Low-frequency rTMS is well tolerated but not effective in treating chronic tinnitus based on the current analysis of pooled data. Further studies with modified and uniform protocols are required to investigate the potential benefit of rTMS in chronic tinnitus.

RESUMEN

OBJECTIVE: To investigate clinical effect of minimally invasive osteotomy and external fixation with the center of roration of angulation (CORA) in treating cubitus varus in adolescents. METHODS: From August 2013 to August 2017, 15 patients with cubitus varus caused by supracondylar fracture of humerus were treated with minimally invasive osteotomy and external fixation with the CORA. Among them, including 9 males and 6 females; 11 patients on the left side and 4 patients on the right side; aged from 13 to 16 years old with an average of 14.5 years old. The time from injury to operation was for 6 to 10 years with an average of 7.5 years. Five patients had a history of recurrence after cubitus varus surgery. Correction time. fracture healing time, carrying angle were observed, Laupattarakasem standard was used to evaluate clinical effect. RESULTS: All patients were followed up from 12 to 30 months with an average of 24 months; correction time ranged from 3 to 5 weeks with an average of 4 weeks; fracture healing time ranged from 4 to 6 months with an average of 5 months; carrying angle before operation ranged from -12° to -23°, and improved 9° to 14° after operation. According to Laupattarakasem evaluation criteria, 11 patients got an excellent result, 3 good and 1 fair. CONCLUSIONS: Minimally invasive osteotomy and external fixation with CORA in treating cubitus varus deformity in adolescents has advantages of less trauma, less blood loss, earlier exercise, speed and angle of correction could controlled without hospitalized for fixation.

RESUMEN

BACKGROUND: Several studies have demonstrated that repetitive transcranial magnetic stimulation (rTMS) may have a beneficial effect in Alzheimer's disease (AD). Nevertheless, the clinical benefit of rTMS for AD remains inconclusive. OBJECTIVE: This systematic review and meta-analysis aimed to evaluate the efficacy and safety of rTMS in AD. METHODS: We searched PubMed, Embase and Cochrane for randomized controlled trials (RCTs) of rTMS for AD. We calculated pooled estimates of mean difference (MD) with 95% confidence intervals (CI). The protocol was registered at International Prospective Register of Systematic Reviews (PROSPERO) (number CRD42018089990). RESULTS: Five RCTs involving 148 participants were included in this review. Compared with sham stimulation, high-frequency rTMS led to a significant improvement in cognition as measured by ADAS-cog (MD = -3.65, 95% CI -5.82 to -1.48, p = 0.001), but not MMSE (MD = 0.49, 95% CI -1.45 to 2.42, p = 0.62). High-frequency rTMS also improved the global impression in comparison to the placebo (MD = -0.79, 95% CI -1.24 to -0.34, p = 0.0006). There was no significant difference in mood (MD = -1.36, 95% CI -3.93 to 1.21, p = 0.30) and functional performance (MD = 0.59, 95% CI -1.21 to 2.38, p = 0.52) between high-frequency rTMS and sham groups. Only one trial included low-frequency rTMS reported no significant improvement in cognition, mood and functional performance. Few mild adverse events were observed in both the rTMS and sham groups. CONCLUSIONS: RTMS is relatively well tolerated, with some promise for cognitive improvement and global impression in patients with AD. Our findings also indicate the variability between ADAS-cog and MMSE in evaluating global cognitive impairment.

RESUMEN

OBJECTIVE: To discuss the effectiveness of Ilizarov technology combined with tarsal V-shape osteotomy for the treatment of traumatic clubfoot. METHODS: Between August 2011 and August 2014, 14 patients with traumatic clubfoot were treated. There were 10 males and 4 females, aged 13 to 61 years (mean, 31 years). of 14 cases, 11 had open fractures of the tibia and ankle and 3 had closed fracture of the ankle joint. The interval from trauma to operation was 7-78 months (mean, 36 months). The plantar flexion of the ankle was 44-89° (mean, 57°). After invasive foot soft tissue release and tarsal V-shape osteotomy, the Ilizaroy external fixator with elastic stretching rod was used. At 5-12 weeks after operation, the neutra pos ofthe ankle joint was restored. Then the neutral position of the ankle joint was maintained for 8 to 12 weeks. After removal of external fixator, protective walking brace was used for 8 to 12 weeks. RESULTS: Infection occurred in 9 cases, and was cured after symptomatic treatment. The patients were followed up 10-36 months (mean, 15 months). After treatment, 14 patients had normal appearance of the ankle joint, and X-ray films showed normal structure of the ankle. The ankle dorsal extension was 10° in 9 patients, who had normal walking function; it was 5° in 4 patients, who could walk; in 1 case of neutral position, the foot had no function of up and down stairs. One case had pain during correction because of poor tolerance, and delay traction was given, the function was recovered to normal after active rehabilitation training. According to the International Clubfoot Study Group (ICFSG) score standard, the results were excellent in 9 cases, good in 4 cases, and fair in 1 case; the excellent and good rate was 92.9% at last follow-up. CONCLUSION: Ilizarov external fixation combined with V-shape osteotomy is effective for the treatment of traumatic clubfoot, with the advantages of less trauma, reliable fixation, satisfactory correction of the deformity, and good function recovery of the ankle.

RESUMEN

The mechanisms of general anesthesia, which was introduced about 170 years ago, remain poorly under- stood. Even less well understood are the effects of general anesthesia on the human body. Recently we identified 18 G-protein coupled receptor (GPCR) genes of Daphnia pulex, an invertebrate model organism. Phylogenetic analysis identified these genes to be the homologs of the human γ-aminobutyric acid, type B (GABAB) receptor, metabotropic glutamate receptors (mGluR), adrenergic receptor, serotonin (5-HT) receptor, dopamine receptor and muscarinic acetylcholine receptor (mAChR). Using reverse transcription and quantitative PCR techniques, we systematically measured the effects of propofol, etomidate and ethanol on these 18 GPCR mRNA expressions in Daphnia pulex.

RESUMEN

BACKGROUND: Over the last few decades intensive studies have been carried out on the molecular targets mediating general anesthesia as well as the effects of general anesthetics. The γ-aminobutyric acid type A receptor (GABAAR) has been indicated as the primary target of general anaesthetics such as propofol, etomidate and isoflurane, and sedating drugs including benzodiazepines and barbiturates. The GABAAR is also involved in drug tolerance and dependence. However, the involvement of other ion channels is possible. METHODS: Using reverse transcription and quantitative PCR techniques, we systematically investigated changes in the mRNA levels of ion channel genes in response to exposure to midazolam, pentobarbital and ketamine in a freshwater model animal, Daphnia pulex. To retrieve the sequences of Daphnia ion channel genes, Blast searches were performed based on known human or Drosophila ion channel genes. Retrieved sequences were clustered with the maximum-likelihood method. To quantify changes in gene expression after the drug treatments for 4 hours, total RNA was extracted and reverse transcribed into cDNA and then amplified using quantitative PCR. RESULTS: A total of 108 ion channel transcripts were examined, and 19, 11 and 11 of them are affected by midazolam (100 µM), pentobarbital (200 µM) and ketamine (100 µM), respectively, covering a wide variety of ion channel types. There is some degree of overlap with midazolam- and pentobarbital-induced changes in the mRNA expression profiles, but ketamine causes distinct changes in gene expression pattern.In addition, flumazenil (10 µM) eliminates the effect of midazolam on the mRNA expression of the GABAA receptor subunit Rdl, suggesting a direct interaction between midazolam and GABAA receptors. CONCLUSIONS: Recent research using high throughput technology suggests that changes in mRNA expression correlate with delayed protein expression. Therefore, the mRNA profile changes in our study may reflect the molecular targets not only in drug actions, but also in chronic drug addiction. Our data also suggest the possibility that hypnotic/anesthetic drugs are capable of altering the functions of the nervous system, as well as those non-nerve tissues with abundant ion channel expressions.

RESUMEN

BACKGROUND: Infantile spasms (IS) is an age-specific and severe epileptic encephalopathy that occurs in infancy and early childhood and is usually refractory to conventional antiepileptic drugs. Adrenocorticotropic hormone (ACTH) has been the treatment of choice for IS, but ACTH use has been associated with infection and hypertension. Magnesium ion is an N-methyl-D-aspartic acid (NMDA)-noncompetitive antagonist that might inhibit NMDA activity and has antiepileptic and neuroprotective effects. OBJECTIVE: This study compared the efficacy and tolerability of ACTH + magnesium sulfate (MgSO(4)) versus ACTH monotherapy for the treatment of IS. METHODS: This 24-week, randomized, open-label follow-up study enrolled male and female infants with IS. Patients were randomly assigned to receive ACTH 25 U/d + MgSO(4) 0.25 g/kg/d, or ACTH 25 U/d only (control), intravenously for 3 weeks. Efficacy was assessed over a period of 24 weeks based on seizure frequency, EEG, and Gesell testing of psychomotor skills (subscales: language, motor, adaptive, and personal-social skills; measured using a developmental quotient [DQ] ). Tolerability was assessed by monitoring for adverse events using laboratory analysis and clinical evaluation. RESULTS: Thirty-eight infants were enrolled (23 male, 15 female; median age, 9.2 months; 19 patients per group). At 12 weeks, 14 patients (73.7%) who received ACTH + MgSO(4) and 9 patients (47.4%) in the control group were seizure free. At 24 weeks, seizure-free rates were 12 (63.2%) in the ACTH + MgSO(4) group and 10 (52.6%) in the control group. On EEG, 9 patients (47.4%) in the ACTH + MgSO(4) group achieved complete recovery (normalized EEG), 5 (26.3 %) attained partial improvement (multifocal spike wave), and 5 (26.3%) had no improvement (hypsarrhythmia or modified hypsarrhythmia). At 4 weeks, in the control group, 5 patients (26.3 %) achieved complete recovery, 6 (31.6%) achieved partial improvement, and 8 (42.1%) had no improvement. Of the 12 patients who were seizure free at 24 weeks in the ACTH + MgSO(4) group, 11 (91.7%) had complete recovery (normalized EEG); this rate was 7 of 10 (70.0%) in the control group. In the ACTH + MgSO(4) group, the change from baseline to 24 weeks in mean (SD) personal-social DQ was significant (from 48.6 [6.4] to 65.2 [7.1], respectively; P < 0.05). In the control group, the difference before and after treatment was nonsignificant (47.7 [6.0] vs 49.9 [4.4]). None of the other Gesell test findings were significant versus baseline. The most common AEs included upper respiratory tract infection and pyrexia (both, 3 [15.8%] per group); diarrhea (2 [10.5%] per group); and hypertension, insomnia, and irritability (all, 0 in the ACTH + MgSO(4) group and 2 [10.5%] in the control group). None of the between-group differences in the prevalences of AEs were significant between the 2 groups. CONCLUSIONS: In this study in infants with IS, the proportions of patients who were seizure free from 4 to 24 weeks were significantly greater in the ACTH + MgSO(4) group compared with the ACTH monotherapy group. Personal-social neurodevelopment was significantly improved from baseline in the group that received combination treatment. Both treatments were generally well tolerated. International Standard Randomized Controlled Trial no. ISRCTN 78654111.
