RESUMEN

The impact of acupuncture on knee function and pain intensity following knee replacement remains controversial. Therefore, we categorized the post-surgery recovery period into three phases: short-term (≤ 2 weeks), intermediate term (2 weeks ~3 months) and long-term (> 3 months), and then assessed the effectiveness of acupuncture in improving function and alleviating pain at different stages following knee replacement. This meta-analysis included randomized controlled trials that compared acupuncture intervention with either no-treatment or a sham group after knee replacement. Six databases were searched from inception to December 31, 2023, including PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, and two Chinese databases (Chinese National Knowledge Infrastructure, and WanFang Data). A total of 23 studies comprised of 1,464 participants were included. Significant improvement of active range of motion was observed on Day 7 and week 2 after operation. Lower pain intensity at rest was noted in patients receiving acupuncture in short-term periods after operation (12 h, Day 1, Day 2, Day 5, and Week 2). A reduction in pain intensity during movement with acupuncture was observed on postoperative Day 1 and Day 7. Auricular acupuncture did not show not significant effectiveness in improving range of motion and pain intensity. For conventional acupuncture, the combination of distal and local point selection was found to be the most effective. Early application of acupuncture, in conjunction with physical therapy, starting before postoperative Day 1 or day 2 was recommended. Further high-quality researches are warranted to validate the findings in this meta-analysis. REGISTRATION ID: The study was registered on PROSPERO (CRD42024503479). PERSPECTIVE: This article demonstrates that acupuncture have short-term effects (≤ 2 weeks) on improving active range of motion, and reducing pain rest and during movement following knee replacement surgery. The findings support the early application of acupuncture in hospital settings after knee replacement.

RESUMEN

BACKGROUND: In the quest to manage hepatocellular carcinoma (HCC), the focus has shifted to a more holistic approach encompassing both data analytics and innovative treatments. Analyzing rich data resources, such as the cancer genome atlas (TCGA), and examining progressive therapies can potentially reshape the trajectory of HCC treatment. AIM: To elucidate the immunological genes and the underlying mechanism of the combined Kombo knife and sorafenib regimen for HCC by analyzing data from TCGA and machine learning data. METHODS: Immune attributes were evaluated via TCGA's postablation HCC RNA sequencing data. Using weighted gene coexpression network analysis and machine learning, we identified genes with high prognostic value. The therapeutic landscape and safety metrics of the integrated treatment were critically evaluated across cellular and animal models. RESULTS: Immune genes-specifically, peptidylprolyl isomerase A and solute carrier family 29 member 3-emerged as significant prognostic markers. Enhanced therapeutic outcomes, such as prolonged progression-free survival and an elevated overall response rate, characterize the combined approach, with peripheral blood mononuclear cells displaying potent effects on HCC dynamics. CONCLUSION: The combination of Kombo knife with sorafenib is an innovative HCC treatment modality anchored in immune-centric strategies.

RESUMEN

BACKGROUND: Transcultural capacity is a key component of consolidated global public health assistance cooperation (GPHAC). The aim of this study is to investigate the transcultural capacity perceptions of public health professionals from China's disease control and prevention system after relative training in order to provide a reference for enhancing transcultural capacity during the practice of GPHAC. METHODS: A cross sectional qualitative survey in which self-administrated questionnaire with 5 open ended questions was used. The questionnaire was disseminated on the completion of an online training for China's senior public health professions on transcultural capacity in GPHAC. Descriptive statistics, word frequency analysis and content analysis were used to analyze the questionnaire data. RESULTS: Totally, 45 participants took part in this training, 25 of them voluntarily participated in this survey. The participants demonstrated the need for transcultural competence in public health services and suggested improvement in the course content arising from their wealth of knowledge and practical experience in the field. 96% of the participants considered that the training course was "very necessary" and "meaningful". The most interested topics were "Overview of transcultural adaptation and GPHAC", "Transcultural adaptation and response" and "African culture and health". The contents about "Country-specific analysis on cultural factors in public health", "rapid transcultural adaptation" and "more specific practical experiences in diverse cultural backgrounds" were suggested to be added in future training. The participants considered that transcultural capacity ensured the smooth progress of GPHAC and they both could complement each other, transcultural adaptation was the premise of gaining trust and reaching cooperation, it can be conducive to the health assistance professionals to integrate into local cultural life, facilitating their foreign assistance work to be effective and efficient, and impart experiences well. The participants hoped to put the concept into action. CONCLUSION: The importance of transcultural competence in GPHAC is becoming a consensus of public health professionals. Enhanced transcultural competence reflected in the attitude of public health as well as other health workers would promote GPHAC and would foster efficient emergency health response management among many countries.

RESUMEN

This study aimed to test cinobufacini therapeutic potential for pancreatic cancer, verify its potential molecular mechanism, and evaluate the cinobufacini impact on pancreatic cancer microenvironment. First, the effect of cinobufacini-treated pancreatic stellate cells (PSCs) supernatant on the value-added ability of pancreatic cancer (PCCs) was tested. The results show that cinobufacini can effectively reduce the ability of PSCs supernatant to promote the value-added PCCs. Further results show that cinobufacini can effectively reduce the concentration of TGFß in the supernatant of PSCs. Subsequently, the impact of cinobufacini on the transcription and translation levels of key genes in the TGFß/Smads pathway was examined. The results showed that the impact of cinobufacini on the transcription levels of Smad2, Smad3, and Smad7 was in a concentration-dependent manner, while the transcriptional activity of collagen I mRNA was decreased with the increase of cinobufacini concentration. The results of protein expression showed that cinobufacini could upregulate the expression of inhibitory protein Smad7, inhibit the phosphorylation level of p-Smad2/3, and then suppress the expression of type I collagen (collagen I). On the one hand, this study shows that cinobufacini can inhibit the promotion of PSCs on the proliferation of PCCs. On the other hand, cinobufacini can upregulate the expression of the inhibitory molecule, Smad7, through the TGFß/Smads pathway and reduce the phosphorylation level of p-Smad2/3, thereby inhibiting the expression of collagen I and pancreatic fibrosis. cinobufacin can inhibit the proliferation of SW1900 cells by blocking the TGFß/Smads pathway of pancreatic stellate cells. These results provide a clinical basis for the treatment of pancreatic cancer.

RESUMEN

Thelazia callipaeda, T. californiensis and T. gulosa are three causative agents of human thelaziasis. Most of the reported cases were caused by T. callipaeda, occurring in the old world, particularly in Asian and European countries. T. californiensis and T. gulosa have rarely been reported infecting humans in North America. T. callipaeda has long been called the oriental eye worm, referring to its traditional distribution across eastern and southeastern Asia (i.e., China, Korea, Japan, Indonesia, Thailand, and India) where infection is endemic in animals and humans, usually in poorer rural areas and mainly among children and the elderly. The identification of the parasite was mainly based on the characteristics of oral and genital organs. In Asia and Europe, vectors for this nematode are male Phortica okadai and P. variegata drosophilids respectively, which feed on ocular secretions of hosts and transmit infective stage larvae to domestic and wild carnivores, lagomorphs, and humans. China probably has the largest number of cases with thelaziasis in the world, and lots of cases have been existed in other Asian countries such as Japan and Korea. Although a few of human cases have been reported, there were high infection rates of wild animals and domesticated dogs and cats in most of European countries. Based on the cox1 gene, a total of 21 haplotypes were identified in the samples from worldwide, in which, one circulated only in European countries (h1), while the other 20 haplotypes were distributed in Korea, Japan and China. In general, the Chinese clinical isolates of T. callipaeda expressed high genetic diversity. The population differences between Europe and Asian countries were greater than those among China, Korea and Japan. The T. callipaeda populations from Europe and Asia should be divided into two separate sub-populations. These two groups started to diverge during the middle Pleistocene.

RESUMEN

BACKGROUND: To evaluate short- and long-term outcomes of robotic gastrectomy (RG) in patients with gastric cancer to determine whether RG is an acceptable alternative to laparoscopic gastrectomy (LG). METHODS: PubMed, Embase, the Cochrane Library, and Chinese Biomedical Database were searched for prospective observational studies (POSs) comparing RG with LG for gastric cancer until October 2017. We compared short-term and long-term outcomes using systematic review with meta-analysis and trial sequential analysis (TSA). RESULTS: Sixteen POSs including 4576 patients were included in the meta-analyses. Compared with LG, RG had longer operative time (MD 57.98 min, P < 0.00001), lesser blood loss (MD - 23.71 ml, P = 0.005), and shorter time to first post-operative flatulence (MD - 0.14 days, P = 0.03). No significant difference was found in terms of the number of harvested lymph nodes, complications, reoperation, mortality, open conversion, proximal resection margin, and distal resection margin. The meta-analyses of complications, overall survival, and disease-free survival did not yield any sign of statistically significant difference between the two treatments, and the cumulative Z-curve crossed neither the traditional boundary nor the trial sequential monitoring boundary, suggesting the lack of firm evidence. TSA demonstrated that the cumulative Z-curve crossed either the traditional boundary or the trial sequential monitoring boundary on blood loss and operative time. CONCLUSIONS: The present study demonstrates that RG is as acceptable as LG in terms of short- and long-term outcomes. The TSA demonstrated that further studies are not needed to evaluate the operative time and blood loss differences between these techniques.

RESUMEN

A series of new trimethoxyphenyl-4H-chromen derivatives as telomerase inhibitors through regulation dyskerin were designed and synthesised. The anticancer activity assay in vitro showed that compound 5i 3-(4-(4-isonicotinoylpiperazin-1-yl)butoxy)-5,7-dimethoxy-2-(3,4,5-trimethoxyphenyl)-4H-chromen-4-one exhibited high activity against Hela, SMMC-7721, SGC-7901, U87 and HepG2 cell lines. Compound 5i also showed potent inhibitory activity against telomerase. The further results confirmed this title compound could significantly improve pathological changes induced rat hepatic tumor in vivo. Preliminary mechanisms showed that compound 5i inhibited telomerase activity through decrease expression of dyskerin.

RESUMEN

The purpose of this study was to examine the possible mechanism underlying the protective effect of tetramethylpyrazine (TMP) against disuse-induced muscle atrophy. Sprague-Dawley rats were randomly assigned to receive 14 days of hindlimb unloading (HLU, a model of disuse atrophy) or cage controls. The rats were given TMP (60 mg/kg body mass) or vehicle (water) by gavage. Compared with vehicle treatment, TMP significantly attenuated the loss of gastrocnemius muscle mass (-33.56%, P < 0.01), the decrease of cross-sectional area of slow fiber (-10.99%, P < 0.05) and fast fiber (-15.78%, P < 0.01) during HLU. Although TMP failed to further improve recovery of muscle function or fatigability compared with vehicle treatment, it can suppress the higher level of lactate (-22.71%, P < 0.01) induced by HLU. Besides, TMP could effectually reduce the increased protein expression of muscle RING-finger protein 1 induced by HLU (-14.52%, P < 0.01). Furthermore, TMP can ameliorate the calcium overload (-54.39%, P < 0.05), the increase of malondialdehyde content (-19.82%, P < 0.05), the decrease of superoxide dismutase activity (21.34%, P < 0.05), and myonuclear apoptosis (-78.22%, P < 0.01) induced by HLU. Moreover, TMP significantly reduced HLU-induced increase of Bax to B-cell lymphoma 2 (-36.36%, P < 0.01) and cytochrome c release (-36.16%, P < 0.05). In conclusion, TMP attenuated HLU-induced gastrocnemius muscle atrophy through suppression of Ca2+/reactive oxygen species increase and consequent proteolysis and apoptosis. Therefore, TMP might exhibit therapeutic effect against oxidative stress, cytosolic calcium overload, and mitochondrial damage in disuse-induced muscle atrophy.

RESUMEN

BACKGROUND: Enhanced recovery programs have become an important focus of perioperative management. A few studies have demonstrated the efficacy of an enhanced recovery after surgery (ERAS, which includes optimized pain control, restricted I.V. fluids, early initiation of postoperative oral feeding, and enforced mobilization) protocol in patients undergoing radical gastrectomy. We investigated the feasibility and safety of laparoscopic radical gastrectomy within ERAS programs. METHODS: In this single-center prospective randomized controlled trial conducted between September 2013 and August 2014, 149 consecutive locally advanced gastric cancer patients (T2-4, any N, M0) diagnosed by the CT scanning were allocated to either ERAS group (N = 73) or conventional pathway group (N = 76). The same surgical technique was used in both groups, that is, laparoscopic gastrectomy with D2 lymphadenectomy and R0 resection. Intergroup differences were evaluated for clinical parameters and C-reactive protein for testing tissue injury. RESULTS: ERAS combined with laparoscopic gastrectomy was observed in our study. Recovery parameters such as time to return to normal diet (days) 1.90 ± 0.71 versus 3.52 ± 0.81, P = .003 and time to the first defecation (days) 2.97 ± 1.23 versus 5.20 ± 1.81, P = .015 were measured. The post hospital stay (days) in ERAS and the conventional care group were 6.38 ± 2.04 and 8.62 ± 2.87, P < .001, respectively. No statistically significant intergroup differences were observed in terms of postoperative complications and C-reactive protein levels. One patient in the ERAS group was readmitted because of anastomotic leakage. No instances of deaths were reported during the 30-day follow-up period. CONCLUSION: This study demonstrates the feasibility and safety of ERAS protocol in advanced gastric cancer patients undergoing laparoscopic radical gastrectomy and was associated with shorter duration of hospital stay.

RESUMEN

China still depends on coal for more than 60% of its power despite big investments in the process of shifting to nuclear, solar and wind power renewable energy resources alignment with Paris climate change agreement (Paris CCA). Chinese government through the Communist Party Central Committee (CPCC) ascribes great importance and commitment to Paris CCA legacy and history landmark implementation at all levels. As the world's biggest carbon dioxide emitter, China has embarked on "SMART" pollution and climate changes programs and measures to reduce coal-fired power plants to less than 50% in the next five years include: new China model of energy policies commitment on CO2 and greenhouse gas emissions reductions to less than 20% non-fossil energy use by 2030 without undermining their economic growth, newly introduced electric vehicles transportation benefits, interactive and sustained air quality index (AQI) monitoring systems, decreasing reliance on fossil fuel economic activities, revision of energy price reforms and renewable energy to less energy efficient technologies development. Furthermore, ongoing CPCC improved environmental initiatives, implemented strict regulations and penalties on local companies and firms' pollution production management, massive infrastructures such as highways to reduce CO2 expansion of seven regional emissions trading markets and programs for CO2 emissions and other pollutants are being documented. Maximizing on the centralized nature of the China's government, implemented Chinese pollution, climate changes mitigation and adaptation initiatives, "SMART" strategies and credible measures are promising. A good and practical example is the interactive and dynamic website and database covering 367 Chinese cities and providing real time information on environmental and pollution emissions AQI. Also, water quality index (WQI), radiation and nuclear safety monitoring and management systems over time and space. These are ongoing Chinese valuable and exemplary leadership in Paris CCA implementation to the global community. Especially to pragmatic and responsible efforts to support pollution and climate changes capacity development, technology transfer and empowerment in emissions surveillance and monitoring systems and "SMART" integrated climate changes mitigation packages in global Sustainable Development Goals (SDGs) context, citizenry health and wellbeing.

RESUMEN

OBJECTIVE: To observe the relation between Pi deficiency syndrome (PDS) and the configuration and functions of extensor digitorum longus (EDL)and soleus (SOL). METHODS: Totally 36 ICR mice were randomly divided into 3 groups according to weight matching principle, the control group, the exhausted group, and the rhubarb group, 12 in each group. Two PDS models were established by either purgation with rhubarb diarrhea (as Group A) or exhausted swimming plus sleep deprivation (as Group B).The cross sectional area (CSA) of type I and II fibers of extensor digitorum longus (EDL) and soleus (SOL), relative proportions of type I and II fibers were measured by m-ATPase histochemical method. The isotonic contraction and the maximum tetanus contraction of EDL and SOL were detected by PowerLab system. RESULTS: Compared with the control group, the body weight, body temperature, and the general health condition of PDS model rats obviously decreased; the spleen index and the thymus index were also lower; the maximal isotonic contraction and the maximum tetanus contraction obviously decreased; the cross section areas of EDL and SOL were reduced with loosely arranged cells. In EDL, the proportion of type I fibers was added and the proportion of type II fibers was lowered. In SOL, there was no change in the proportion of type I and type II fibers. CONCLUSIONS: EDL and SOL were obviously atrophied in the two PDS model mice. The type I fibers of SOL was more significantly atrophied in Group B.

RESUMEN

OBJECTIVE: (i) To determine whether clinical features and biochemical parameters help to predict survival of methylmalonic acidemia with homocystinuria; (ii) To find the cutoff values of biochemical parameters for predicting survival of methylmalonic acidemia with homocystinuria. DESIGN: A prospective cohort study. SETTING: A pediatric tertiary hospital in Beijing; all patients were followed until death or June 2013. SUBJECTS: 45 pediatric patients diagnosed with methylmalonic acidemia with homocystinuria between 2006 and 2012. OUTCOME MEASURES: The data of clinical characteristics and pretreatment biochemical parameters were collected. The Cox regression analysis was performed to identify independent risk factors for survival of patients with methylmalonic acidemia and homocystinuria. The best cutoff values for these independent factors were determined by the receiver characteristic curve. RESULTS: Newborn onset (OR=6.856, 95%CI=2.241-20.976, P=0.001), high level of methylmalonic acid in urine (OR=1.022, 95%CI=1.011-1.033, P<0.001), and high level of urea in serum (OR=1.083, 95%CI=1.027-1.141, P=0.003) were independent negative risk factors for survival of patients with methylmalonic acidemia and homocystinuria. The cutoff values of maximum predictive accuracy of methylmalonic acid in urine and urea in serum were respectively 5.41 mmol/mmol creatinine and 7.80 mmol/L by receiver operating characteristic curve analysis. CONCLUSIONS: The patients of methylmalonic acidemia with homocystinuria tend to have an adverse outcome if they have newborn onsets. Elevated urea and urinary methylmalonic acid are predictors of adverse outcomes for the patients. They show similar effect for predicting severe adverse prognosis. The combination of methylmalonic acid in urine concentration and urea in serum concentration provided the most accurate predictive tool.

RESUMEN

Root anatomical structures of four rice breeding materials (maintainer lines YixiangB and E2B, restorer lines R892 and Mianhui725), grown under different Cd2+ levels, were observed and the root resistance to Cd2+ ions was evaluated. Under low Cd stress, the new roots appeared in the cortex of four rice genotypes. The diameter of the new root in YixiangB was larger than that of E2B. The restorer line R892 generated more roots than Mianhui725. Under high Cd2+ stress, broken epidermis, damaged cortex and black spots appeared in both maintainer and restorerlines. In general, anatomical damages in the restorer lines (R892 and Mianhui725) were slighter than those of the maintainer lines (YixiangB and E2B). Thus, the restorer lines had more adaptive ability to Cd2+ stress than maintainer lines.

RESUMEN

BACKGROUND: Atypical right bundle branch block (RBBB) may present with an rS pattern and notched S wave in lead V1 . The notched S wave may represent slowed conduction or delayed activation of the right ventricular conduction system or ventricular myocardium. METHODS: We retrospectively analyzed the QRS patterns in accessory right precordial leads (from V3 R to V5 R) in 15 adults/senior individuals with notched S wave in lead V1 . RESULTS: In the right accessory precordial leads, 13 showed triphasic QRS pattern with final R' wave in their QRS complexes. This QRS pattern in association with notched S wave in lead V1 is suggestive of the presence of RBBB (incomplete or complete). CONCLUSIONS: A notched S wave in lead V1 and in the right precordial accessory leads associated with a final R' wave suggests the possibility of concealed RBBB (incomplete or complete).

RESUMEN

BACKGROUND: Acute pulmonary embolism (APE) is often misdiagnosed as acute coronary syndrome because of the similarity of the presenting symptoms and of the electrocardiogram (ECG) manifestations. In APE, ST-segment elevation (STE) in leads V1 to V3 /V4 , mimicking anteroseptal myocardial infarction, is not a rare phenomenon. Negative T waves (NTW) in the precordial leads mimicking the "Wellens' syndrome" is an important ECG manifestation of APE. The evolution of these ECG changes-STE and NTW-in APE has not been thoroughly studied. METHODS: We present two patient cases with APE and their evolving serial ECGs to analyze the correlation between STE and NTW. RESULTS: NTW developed later than STE in these two patient cases. CONCLUSIONS: NTW might represent a "postischemic" ECG pattern indicating a previous stage with transmural myocardial ischemia.

RESUMEN

OBJECTIVE: To identify the major ecological drivers for malaria vector density using the structural equation model (SEM) in the Three Gorges Reservoir. METHOD: An 11-year longitudinal surveillance of malaria vector as well as its related ecological factors was carried out in the Three Gorges Reservoir. The Delphi method was used to identify associated ecological factors. The structural equation model was repeatedly corrected and improved by the corrected index, combined with the actual situation. The final model was defined by relative simplicity, best fitting as well as the practicality. RESULT: The final model indicated that the direct effects of temperature, livestock, humidity, and breeding on the vector were 0.015, -0.228, 0.450, 0.516 respectively, their total effects on the vector were 0.359, -0.112, 0.850, and 0.043 through different pathways. CONCLUSION: SEM was effective and convenient in elucidating the mechanism by which malaria vector dynamics operated in this study. It identified that the breeding had the highest direct effect on vector and played a key role for mediating effect of temperature and humidity.

RESUMEN

Takotsubo cardiomyopathy (TTC) is characterized by acute and reversible ventricular dysfunction in the absence of significant coronary artery disease, typically triggered by acute emotional or physical stress. In the acute phase of TTC, the electrocardiogram (ECG) shows ST-segment elevation, which rapidly evolves into negative T waves and QT prolongation. However, different types of ventricular dysfunction may be associated with different patterns of ECG presentation. In this paper, we discuss the correlation between ECG presentation and cardiovascular magnetic resonance imaging in TTC.

RESUMEN

BACKGROUND: Possible similarities or differences in the ST- and PR-segment deviations in the electrocardiogram of takotsubo cardiomyopathy (TTC) and acute pericarditis (AP) are not well defined. METHODS: We compared different parameters of the admission electrocardiogram in eight patients with TTC and eight patients with AP with ST-segment elevation in the acute phase. RESULTS: We found significant differences in the maximal magnitude of the T wave in the precordial leads, but not in the ST- and PR-segment deviation patterns between the two patient groups. All the patients in the two groups showed consistent ST-segment depression in lead aVR and absence of ST-segment elevation in lead V1. CONCLUSIONS: The ST- and PR-segment deviation patterns in TTC are similar to that of AP, namely diffuse ST-segment elevations with reciprocal changes in aVR and V1 and PR-segment elevation in aVR accompanied by PR-segment depression in the inferior leads, possibly indicating that TTC has ECG characteristics of circumferential subepicardial ischemia in the acute phase.

RESUMEN

Microbial community structure and ecological functions are influenced by interactions between above and belowground biota. There is an urgent need for intensive monitoring of microbes feedback of soil micro-ecosystem for setting up a good agricultural practice. Recent researches have revealed that many soils characteristic can effect microbial community structure. In the present study factors affecting microbial community structure and soil in Carthamus tinctorius plantations in arid agricultural ecosystem of northern Xinjiang, China were identified. The result of the study revealed that soil type was the key factor in safflower yield; Unscientific field management resulted high fertility level (bacteria dominant) of soil to turn to low fertility level (fungi dominant), and Detruded Canonical Correspondence Analysis (DCCA) showed that soil water content, organic matter, available N, P and K were the dominant factors affecting distribution of microbial community. Soil water content showed a significant positive correlation with soil microbes quantity (P < 0.01), while others showed a significant quantity correlation with soil microbe quantity (P < 0.05).
