RESUMEN
BACKGROUND: Accumulating evidence suggests that the inflammatory cytokine interleukin-6 (IL-6) contributes to the pathophysiology of psychiatric disorders. However, there was no study concerning the relationship between IL-6 concentrations and clinical features in the chronic phase of early-onset schizophrenia (EOS). AIM: To investigate the relationship between serum IL-6 concentration and the clinical features of EOS. METHODS: We measured serum IL-6 Levels from 74 patients with chronic schizophrenia, including 33 with age at onset < 21 years (EOS group) and 41 with onset ≥ 21 years in [adult-onset schizophrenia (AOS) group], and from 41 healthy controls. Symptom severities were evaluated using the Positive and Negative Syndrome Scale (PANSS). RESULTS: Serum IL-6 concentrations were higher in both EOS and AOS groups than healthy controls (F = 22.32, P < 0.01), but did not differ significantly between EOS and AOS groups (P > 0.05) after controlling for age, body mass index, and other covariates. Negative symptom scores were higher in the EOS group than the AOS group (F = 6.199, P = 0.015). Serum IL-6 concentrations in the EOS group were negatively correlated with both total PANSS-negative symptom score (r = -0.389, P = 0.032) and avolition/asociality subscore (r = -0.387, P = 0.026). CONCLUSION: Patients with EOS may have more severe negative symptoms than those with adult-onset schizophrenia during the chronic phase of the illness. IL-6 signaling may regulate negative symptoms and its avolition/asociality subsymptoms among the early-onset chronic schizophrenic patients.
RESUMEN
Purpose: To determine whether using robots in spine surgery results in more clinical advantages and fewer adverse consequences. Methods: Between October 1990 and October 2022, a computer-based search was conducted through the databases of PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure, China Biology Medicine, VIP databases, and WAN FANG. The study only included randomized controlled trials (RCTs) comparing the clinical efficacy and safety of robot-assisted surgery with those of conventional spine surgery. The review was conducted following PRISMA 2020, and AMSTAR-2 was used to evaluate the methodological quality. R version 4.2.1 was used in the meta-analysis. The Cochrane Collaboration Tool was used for evaluating the risk of bias. Results: This study analyzed 954 participants from 20 RCTs involving cervical spondylosis, lumbar degenerative disease, scoliosis, etc. The robot-assisted group outperformed the freehand group in terms of intraoperative blood loss, number of screws in grade A position, grade A + B position, radiation dose, and hospital stay. Operation duration, visual analog scale scores of low back pain, Oswestry disability index, and radiation exposure time did not significantly differ between the two groups. Conclusions: Although robotic spine surgery is more accurate in pedicle screw placement than conventional methods, the robot group did not demonstrate an advantage in terms of clinical efficacy. Studies of complications and cost-effectiveness are still very rare.
RESUMEN
Tui Na or massage therapy alleviates symptoms related to intervertebral disc degeneration (IDD). However, precise, repeatable, standardized instructions for Tuina manipulation are lacking. This study establishes IDD model rabbits induced by fibrous ring puncture, creates targeted Tuina stimulation protocols at the acupuncture points in the lumbar region, and describes in detail the operation methods and requirements of kneading, pointing, and flicking. New Zealand male white rabbits (n = 15) were selected and randomly divided into a blank group, a model group, and a Tuina group. The rabbits in the model group and the Tuina group were molded by fibrous ring puncture; the rabbits in the model group were only immobilized on the operating table without treatment. In contrast, the Tuina group used the "8N/10N, 30 cycles/min" prescription for kneading, pointing, and flicking to perform the intervention, using tactile sensory aids to monitor and regulate the intensity of the Tuina operation. Imaging diagnosis and pathological tests were used to assess the effect of Tuina in rabbits, and the results showed improved imaging features and significantly lowered pathology scores of lumbar disc degeneration in the Tuina group compared to the model group (P < 0.01). Targeted Tuina in the lumbar region may be beneficial in the alleviation of lumbar disc degeneration, but further verification is needed. By regularly performing Tuina and recording the mechanical information involved enables reproducible manipulation prescriptions and helps to observe the basic features of the underlying mechanism of Tuina for IDD.

Objective: The aim of this study was to comprehensively evaluate the efficacy of oblique lateral interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of degenerative lumbar spondylolisthesis by meta-analysis. Methods: A computer-based search of PubMed, Cochrane Library, Embase, Web of Science Core Collection databases, the China National Knowledge Infrastructure, China Biology Medicine, and Wanfang Digital Periodicals was conducted from the time of inception of each database to December 2021. The review process was conducted according to the PRISMA guidelines and registered in the PROSPERO database. Meta-analysis was performed using RevMan 5.4 software provided by the Cochrane Library. Results: Thirteen studies were included in the statistical analysis. One randomized controlled study and 12 cohort studies with 954 patients were included. In terms of operation time, intraoperative blood loss, Oswestry disability index score, intervertebral height, and complications, the OLIF group was better than the TLIF group, and the difference was statistically significant (P < 0.05). There was no significant difference between the two groups in terms of visual analogue scale score, lumbar lordosis or fused segment lordosis (P > 0.05). Conclusion: Both OLIF and TLIF are effective surgical modalities in the treatment of degenerative lumbar spondylolisthesis. They achieve similar therapeutic effects, but OLIF is superior to TLIF in restoring intervertebral height. At the same time, OLIF has the advantages of short operation time and less intraoperative blood loss.
RESUMEN
Background: Most previous studies on acupuncture in the treatment of knee osteoarthritis (KOA) have focused on improving functional efficacy and safety, while related mechanisms have not been systematically reviewed. Acupuncture modulates cytokines to attenuate cartilage extracellular matrix degradation and apoptosis, key to the pathogenesis of KOA, but the mechanisms are complex. Objectives: The purpose of this study is to assess the efficacy of acupuncture quantitatively and summarily in animal studies of KOA. Methods: Nine databases including PubMed, Embase, Web of Science (including Medline), Cochrane library, Scopus, CNKI, Wan Fang, and VIP were searched to retrieve animal studies on acupuncture interventions in KOA published since the inception of the journal. Relevant literature was screened, and information extracted. Meta-analysis was performed using Revman 5.4 and Stata 17.0 software. Results: The 35 included studies involved 247 animals, half of which were in acupuncture groups and half in model groups. The mean quality level was 6.7, indicating moderate quality. Meta-analysis showed that acupuncture had the following significant effects on cytokine levels in p38MAPK and mitochondrial pathways: (1) p38MAPK pathway: It significantly inhibits p38MAPK, interleukin-1beta (IL-1ß), tumor necrosis factor alpha (TNF-α), phosphorylated (p)-p38MAPK, matrix metalloproteinase-13 (MMP-13), MMP-1, a disintegrin and metalloproteinase with thrombospondin motifs-5 (ADAMST-5) expression, and significantly increased the expression of collagen II and aggrecan. (2) mitochondrial pathway: It significantly inhibited the expression of Bcl-2-associated X protein (Bax), cysteine protease-3 (caspase-3), caspase-9, and Cytochrome-c (Cyt-c). And significantly increased the expression of B cell lymphocytoma-2 (Bcl-2). In addition, acupuncture significantly reduced chondrocyte apoptosis, Mankin's score (a measure of cartilage damage), and improved cartilage morphometric characteristics. Conclusion: Acupuncture may inhibit cytokine expression in the p38MAPK pathway to attenuate cartilage extracellular matrix degradation, regulate cytokines in the mitochondrial pathway to inhibit chondrocyte apoptosis, and improve cartilage tissue-related phenotypes to delay cartilage degeneration. These findings provide possible explanations for the therapeutic mechanisms and clinical benefits of acupuncture for KOA.

RESUMEN
BACKGROUND: Since the 1990s, families from the ecologically hostile mountainous southern areas of Ningxia Province, China, have been migrating to the northern areas of the province. This study compared the prevalence of behavioral problems among migrant adolescents to those among host adolescents (adolescents from the northern areas) and adolescents in the region of origin (adolescents from the southern areas), to determine whether ecological migration is related to adolescent behavioral problems, and possible changes in such problems over time. METHODS: We used the Children and Adolescents Ecological Migration Survey on Mental Health, administered to 4805 students aged 12-16 years and their parents between 2012 and 2014 (W1), of whom 1753 students and their parents completed the follow-up between 2014 and 2017 (W2). Parents answered questions related to adolescent behavioral problems, main source of family income, parents' desire to reverse migrate, improved standard of living, and parents' educational attainment, while children completed the Eysenck Personality Questionnaire and a classroom environment questionnaire. RESULTS: The prevalence of behavioral problems among the migrant adolescents (28.04%) was significantly higher than among host adolescents (21.59%) or adolescents in the region of origin (24.37%; p < 0.001) at W1. After adjusting for gender and age, parents' work outside the home was the main source of family income (OR = 1.42, 95% CI = 1.13-1.78), and adolescents' learning burden (OR = 1.04, 95% CI = 1.01-1.06) in school negatively influenced behavioral problems. Strong student-teacher relationships (OR = 0.97,95% CI = 0.94-0.99) and parents who had no intention to move back to the original residence (OR = 0.70, 95% CI = 0.52-0.94) exerted a protective effect at W1; at W2, a protective effect was associated with improved living conditions (OR = 0.39-0.55, 95% CI = 0.25-0.84). The extent of behavioral problems among migrant adolescents significantly decreased after two years. CONCLUSION: Ecological migration will increase children's behavioral problems in the early stage, with various factors influencing the extent of these problems.

AIMS AND OBJECTIVES: To reveal nurses' self-reported practice of managing chest tubes and to define decision-makers for these practices. BACKGROUND: No consensus exists regarding ideal chest-tube management strategy, and there are wide variations of practice based on local policies and individual preferences, rather than standardised evidence-based protocols. DESIGN: This article describes a cross-sectional study. METHODS: Questionnaires were emailed to 31 hospitals in Tianjin, and the sample consisted of 296 clinical nurses whose work included nursing management of chest drains. The questionnaire, which was prepared by the authors of this research, consisted of three sections, including a total of 22 questions that asked for demographic information, answers regarding nursing management that reflected the practice they actually performed and who the decision-makers were regarding eight chest-drain management procedures. McNemar's test was used to analyse the data. RESULTS: The results indicated that most respondents thought that it was necessary to manipulate chest tubes to remove clots impeding unobstructed drainage (91.2%). Most respondents indicated that dressings would be changed when the dressing was dysfunctional. At the same time, more than half of respondents approved of changing dressings routinely, and the frequency of changing dressings varied. When drainage was employed for pleural effusion and for a pneumothorax, 64.6% and 94.5% of respondents, respectively, considered that underwater seal-drainage bottles should be changed routinely, and the frequency of changing bottles both varied. The results indicated that nurses were the primary decision-makers in the replacement of chest tubes, manipulation of chest tubes and monitoring of drainage fluid. CONCLUSIONS: There was considerable variation in respondents' self-reported clinical nursing practice regarding management of chest drains. The rationale on which respondents' practices were based also varied greatly. This study indicated that nurses were the primary decision-makers for three of eight procedures regarding management of chest drains, which reflects that clinical nurses' decision-making power regarding management of chest drains was weak. RELEVANCE TO CLINICAL PRACTICE: This study describes the nurse-reported practices of Chinese nurses from Tianjin, including changing and selecting dressing types, manipulating chest tubes, clamping drains and replacing drainage bottles, and the study defines who the decision-makers were for these interventions. By focusing on nurses' self-report of behaviours in managing chest drains (actual nursing practice vs. nursing knowledge), this article also relates the literature to the research findings and denotes the gaps in knowledge for future research.
