A study on the effect of using the video teach-back method in continuous nursing care of stroke patients.

Objective: To explore the effect of a video teach-back method on continuous family nursing care of stroke patients. Methods: Stroke patients hospitalized in our hospital between March 2020 and March 2023 who met the inclusion criteria were randomly divided into an intervention group (n = 45), who received routine health education plus video teach-back training of caregivers, and a control group (n = 45), who received routine health education only. The effects on nursing-related variables were compared between the two groups. Results: Total scores representing the caring ability of caregivers in the intervention group increased significantly over time relative to baseline and were higher than those of the control group. Scores representing the care burden of caregivers in the intervention group decreased significantly over time and were lower than those of the control group. Conclusion: The teach-back method combined with video education improves the nursing ability of family caregivers and can improve the self-care ability of stroke patients.

Microarray Profiling and Functional Identification of LncRNA in Mice Intestinal Mucosa Following Intestinal Ischemia/Reperfusion.

BACKGROUND: Intestinal ischemia-reperfusion (I/R) injury is a common clinical event with high mortality, but its mechanism is elusive. Although long noncoding RNAs (lncRNAs) have recently emerged as critical molecules in I/R damage in other organs, the changes in their expression and potential roles in intestinal I/R remain unclear. METHODS: The expression profiles of both lncRNAs and mRNAs in mouse intestinal mucosa after intestinal I/R were explored by a microarray approach, and their biological functions were elucidated by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. Then, some lncRNAs were further verified by qRT-PCR. Based on the coding-noncoding gene coexpression (CNC) network analyses, the role of lncRNA AK089510 in intestinal I/R-induced intestinal mucosa apoptosis was investigated by knockdown assay in vitro. RESULTS: A total of 3602 aberrantly expressed lncRNAs (1503 upregulated and 2099 downregulated) and 3158 mRNAs (1528 upregulated and 1630 downregulated) were identified. The dysregulated transcripts were enriched in the lipid metabolic process, apoptotic process, reactive oxygen species metabolic process, MAPK, TNF, ErbB, mTOR, and FoxO signaling pathways, and so on. The overexpression of lncRNA AK089510 was validated by qRT-PCR, and the CNC analysis revealed its target mRNAs. AK089510-siRNA reduced Casp6 and Casp7 expression and suppressed intestinal epithelial cell apoptosis after oxygen-glucose deprivation treatment. CONCLUSIONS: Our study revealed the lncRNA and mRNA expression patterns in mouse intestinal mucosa after intestinal I/R and predicted their potential functions and pathways. We identified AK089510 as a novel lncRNA involved in the apoptosis of intestinal mucosa, advancing our understanding of the molecular mechanisms of intestinal I/R injury.

Terlipressin relieves intestinal and renal injuries induced by acute mesenteric ischemia via PI3K/Akt pathway.

Background: To date, the effect of vasopressin on organ damages after acute mesenteric ischemia (MI) remains poorly understood. Aims: To investigate the effect of terlipressin, a selective vasopressin V1 receptor agonist, versus norepinephrine on the intestinal and renal injuries after acute MI, and to explore the underlying mechanism of terlipressin. Methods: Acute MI model was produced by clamping the superior mesenteric artery for 1 hour. Immediately after unclamping, terlipressin or norepinephrine was intravenously administered for 2 hours. Meanwhile, in vitro, RAW264.7 cells were treated with lipopolysaccharide or lipopolysaccharide+terlipressin. In addition, wortmannin was used to determine the role of phosphoinositide 3-kinase (PI3K)/ protein kinase B (Akt) pathway in the potential impacts of terlipressin. Results: MI led to severe hypotension, caused notable intestinal and renal impairments and resulted in high mortality, which were markedly improved by terlipressin or norepinephrine. Terlipressin increased mean arterial pressure, decreased intestinal epithelial cell apoptosis, inhibited the generation of M1 macrophage in intestinal and renal tissues, and hindered the release of inflammatory cytokines after MI. Moreover, in cultured macrophages, terlipressin reduced the mRNA level of specific M1 markers and the release of inflammatory cytokines caused by lipopolysaccharide challenge. Wortmannin decreased the expression of PI3K and Akt induced by terlipressin in cells and in tissues, and abolished the above protective effects conferred by terlipressin. Conclusions: Terlipressin or norepinephrine could effectively improve organ damages and mortality after acute MI. Terlipressin elevates blood pressure and inhibits intestinal epithelial apoptosis and macrophage M1 polarization via the PI3K/Akt pathway.

Impact of Anxiety or Depression Symptoms on Propofol Requirements for Sedation in Females: A Prospective Cohort Study.

Mental disorders are thought to affect various clinical outcomes during the perioperative period. Among them, anxiety and depression are 2 of the most common types. However, the impacts of anxiety or depression on propofol requirements remain unclear. This study aimed to investigate the effects of anxiety or depression symptoms on the propofol requirements for sedation in females. This study recruited female patients aged 18 to 65 years, with American Society of Anesthesiologists physical status classification of 1 to 2, who were scheduled for hysteroscopic surgery under propofol-based intravenous anesthesia. The day before surgery, the Hospital Anxiety and Depression Scale (HADS) was used to assess the symptoms of anxiety and depression within the past 6 months. Target-controlled propofol was gradually titrated to achieve 3 desired levels of sedation: Modified Observer's Assessment of Alertness/Sedation scale (MOAA/S) score 3, MOAA/S score 1, and MOAA/S score 1 and Narcotrend Index <65. The effect-site concentration of propofol correlated with HADS-Anxiety scores for the sedation levels of MOAA/S 3 and 1 (r = .249, P = .008; and r = .190, P = .045, respectively). However, the propofol requirements did not correlate with HADS-Depression scores at any sedation level. In conclusion, female patients with anxiety symptoms, but not depression symptoms, required a higher dose of propofol for sedation in hysteroscopy.

Intraoperative ventilation strategies to prevent postoperative pulmonary complications: a network meta-analysis of randomised controlled trials.

BACKGROUND: The debate on lung-protective ventilation strategies for surgical patients is ongoing. Evidence suggests that the use of low tidal volume VT improves clinical outcomes. However, the optimal levels of PEEP and recruitment manoeuvre (RM) strategies incorporated into low VT ventilation remain unclear. METHODS: Several electronic databases were searched to identify RCTs that focused on comparison between low VT strategy and conventional mechanical ventilation (CMV), or between two different low VT strategies in surgical patients. The primary outcome was postoperative pulmonary complications (PPCs). The secondary outcomes were atelectasis, pneumonia, acute respiratory distress syndrome, and short-term mortality. Bayesian network meta-analyses were performed using WinBUGS. The odds ratios (ORs) and corresponding 95% credible intervals (CrIs) were estimated. RESULTS: Compared with CMV, low VT ventilation with moderate-to-high PEEP reduced the risk of PPCs (moderate PEEP [5-8 cm H2O]: OR 0.50 [95% CrI: 0.28, 0.89]; moderate PEEP+RMs: 0.39 [0.19, 0.78]; and high PEEP [≥9 cm H2O]+RMs: 0.34 [0.14, 0.79]). Low VT ventilation with moderate-to-high PEEP and RMs also specifically reduced the risk of atelectasis compared with CMV (moderate PEEP+RMs: OR 0.36 [95% CrI: 0.16, 0.87]; and high PEEP+RMs: 0.41 [0.15, 0.97]), whilst low VT ventilation with moderate PEEP was superior to CMV in reducing the risk of pneumonia (OR 0.46 [95% CrI: 0.15, 0.94]). CONCLUSIONS: The combination of low VT ventilation and moderate-to-high PEEP (≥5 cm H2O) seems to confer lung protection in surgical patients undergoing general anaesthesia. CLINICAL TRIAL REGISTRATION: PROSPERO (CRD42019144561).

Gut Barrier Dysfunction Induced by Aggressive Fluid Resuscitation in Severe Acute Pancreatitis is Alleviated by Necroptosis Inhibition in Rats.

Fluid resuscitation is the first-line antishock treatment in severe acute pancreatitis (SAP). Currently, although mentions of complications related to aggressive fluid resuscitation are very frequent, a lack of proper handling of complications remains. One of the most important complications is intestinal barrier injury, including intestinal ischemia-reperfusion injury following aggressive fluid resuscitation. Once injured, the intestinal barrier may serve as the source of additional diseases, including systemic inflammatory response syndrome and multiple organ dysfunction syndrome, which aggravate SAP. This study focused on the underlying mechanisms of gut barrier dysfunction in rats induced by aggressive fluid resuscitation in SAP. This study further indicated the important role of necroptosis in intestinal barrier injury which could be relieved by using necroptosis-specific inhibitor Nec-1 before aggressive fluid resuscitation, thus reducing intestinal barrier damage. We also found pancreas damage after intestinal ischemia/reperfusion challenge and indicated the effects of high mobility group protein B1 in the vicious cycle between SAP and intestinal barrier damage.

Is goal-directed fluid therapy based on dynamic variables alone sufficient to improve clinical outcomes among patients undergoing surgery? A meta-analysis.

BACKGROUND: Whether goal-directed fluid therapy based on dynamic predictors of fluid responsiveness (GDFTdyn) alone improves clinical outcomes in comparison with standard fluid therapy among patients undergoing surgery remains unclear. METHODS: PubMed, EMBASE, the Cochrane Library and ClinicalTrials.gov were searched for relevant studies. Studies comparing the effects of GDFTdyn with that of standard fluid therapy on clinical outcomes among adult patients undergoing surgery were considered eligible. Two analyses were performed separately: GDFTdyn alone versus standard fluid therapy and GDFTdyn with other optimization goals versus standard fluid therapy. The primary outcomes were short-term mortality and overall morbidity, while the secondary outcomes were serum lactate concentration, organ-specific morbidity, and length of stay in the intensive care unit (ICU) and in hospital. RESULTS: We included 37 studies with 2910 patients. Although GDFTdyn alone lowered serum lactate concentration (mean difference (MD) - 0.21 mmol/L, 95% confidence interval (CI) (- 0.39, - 0.03), P = 0.02), no significant difference was found between groups in short-term mortality (odds ratio (OR) 0.85, 95% CI (0.32, 2.24), P = 0.74), overall morbidity (OR 1.03, 95% CI (0.31, 3.37), P = 0.97), organ-specific morbidity, or length of stay in the ICU and in hospital. Analysis of trials involving the combination of GDFTdyn and other optimization goals (mainly cardiac output (CO) or cardiac index (CIx)) showed a significant reduction in short-term mortality (OR 0.45, 95% CI (0.24, 0.85), P = 0.01), overall morbidity (OR 0.41, 95% CI (0.28, 0.58), P < 0.00001), serum lactate concentration (MD - 0.60 mmol/L, 95% CI (- 1.04, - 0.15), P = 0.009), cardiopulmonary complications (cardiac arrhythmia (OR 0.58, 95% CI (0.37, 0.92), P = 0.02), myocardial infarction (OR 0.35, 95% CI (0.16, 0.76), P = 0.008), heart failure/cardiovascular dysfunction (OR 0.31, 95% CI (0.14, 0.67), P = 0.003), acute lung injury/acute respiratory distress syndrome (OR 0.13, 95% CI (0.02, 0.74), P = 0.02), pneumonia (OR 0.4, 95% CI (0.24, 0.65), P = 0.0002)), length of stay in the ICU (MD - 0.77 days, 95% CI (- 1.07, - 0.46), P < 0.00001) and in hospital (MD - 1.18 days, 95% CI (- 1.90, - 0.46), P = 0.001). CONCLUSIONS: It was not the optimization of fluid responsiveness by GDFTdyn alone but rather the optimization of tissue and organ perfusion by GDFTdyn and other optimization goals that benefited patients undergoing surgery. Patients managed with the combination of GDFTdyn and CO/CI goals might derive most benefit.

Association of pre-operative troponin levels with major adverse cardiac events and mortality after noncardiac surgery: A systematic review and meta-analysis.

BACKGROUND: Circulating cardiac troponin levels are powerful predictors of prognosis in many clinical settings, but their association with outcomes after noncardiac surgery is unclear. OBJECTIVES: The aim of this systematic review was to summarise current evidence on the association of pre-operative troponin elevation with postoperative major adverse cardiac events (MACE) and mortality in patients undergoing noncardiac surgery. DESIGN: Systematic review of observational studies with meta-analysis. DATA SOURCES: PubMed, EMBASE and Science Citation Index Expanded (ISI Web of Science) from their inception to 1 October 2017. ELIGIBILITY CRITERIA: Observational studies reporting the associations between pre-operative troponin levels and MACE and all-cause mortality after noncardiac surgeries were included. RESULTS: Ten studies met the eligibility criteria. The entire body of evidence addressing the research question was based on a total of 10 371 patients: 4.7 to 68.3% (median 23.8%) of patients had elevated troponin levels before surgery. Elevated pre-operative troponin was significantly associated with short-term MACE (seven studies, 5180 patients: odds ratio (OR) 6.92, 95% confidence interval (CI) 3.85 to 12.42), short-term mortality (five studies, 6103 patients: OR 4.23, 95% CI 2.27 to 7.89) and long-term mortality (two studies, 760 patients: OR 2.51, 95% CI 1.47 to 4.29). The associations remained significant when only multivariate-adjusted results were analysed. Overall, the reviewers' certainty about the summary estimates of the associations was very low. CONCLUSION: Current evidence suggests that pre-operative high troponin levels are significantly associated with adverse cardiac events and mortality after noncardiac surgery. TRIAL REGISTRATION: This systematic review was registered in the International Prospective Register of Systematic Reviews (Centre for Reviews and Dissemination 42017077837).

Terlipressin protects intestinal epithelial cells against oxygen-glucose deprivation/re-oxygenation injury via the phosphatidylinositol 3-kinase pathway.

Intestinal ischemia/reperfusion (I/R) injury is associated with a high morbidity and mortality. Vasopressin is administered to critically ill patients with potential intestinal I/R. However, the impacts of vasopressin on intestinal epithelia under ischemic/anoxic conditions remain unclear. The aim of the present study was to evaluate the effects of terlipressin, a highly selective vasopressin V1 receptor agonist, on oxygen and glucose deprivation/re-oxygenation (OGD/R)-induced damage in intestinal epithelial cells (IEC-6). IEC-6 cells were subjected to OGD for 4 h, followed by 4 h re-oxygenation. Terlipressin was incubated with cells for 4 h following OGD. Following OGD/R, IEC-6 cell viability, proliferation and apoptosis, as well as cell cycle dynamics, were assessed and the levels of tumor necrosis factor (TNF)-α and 15-F2t-isoprostane in the culture medium were measured. In addition, wortmannin, a specific phosphatidylinositol 3-kinase (PI3K) inhibitor, was administrated to investigate the mechanism of terlipressin action. The results demonstrated that IEC-6 cell viability and proliferation decreased, and cell apoptosis increased, following OGD/R. However, IEC-6 cell cycle dynamics did not significantly change 4 h after OGD. Incubation with 25 nM terlipressin significantly improved cell viability, proliferation and apoptosis. Furthermore, terlipressin inhibited the secretion of TNF-α and 15-F2t-isoprostane from IEC-6 cells following OGD/R. The aforementioned effects of terlipressin were completely abolished following the application of 2 µM wortmannin. Therefore, the current study demonstrated that terlipressin administration following OGD attenuates OGD/R-induced cell damage via the PI3K signaling pathway. These results may help physicians to better understand and more effectively use terlipressin in a clinical setting.

TGF-ß1 improves mucosal IgA dysfunction and dysbiosis following intestinal ischaemia-reperfusion in mice.

Intestinal ischaemia/reperfusion (I/R) severely disrupts gut barriers and leads to high mortality in the critical care setting. Transforming growth factor (TGF)-ß1 plays a pivotal role in intestinal cellular and immune regulation. However, the effects of TGF-ß1 on intestinal I/R injury remain unclear. Thus, we aimed to investigate the effects of TGF-ß1 on gut barriers after intestinal I/R and the molecular mechanisms. Intestinal I/R model was produced in mice by clamping the superior mesenteric artery for 1 hr followed by reperfusion. Recombinant TGF-ß1 was intravenously infused at 15 min. before ischaemia. The results showed that within 2 hrs after reperfusion, intestinal I/R disturbed intestinal immunoglobulin A class switch recombination (IgA CSR), the key process of mucosal IgA synthesis, and resulted in IgA dysfunction, as evidenced by decreased production and bacteria-binding capacity of IgA. Meanwhile, the disruptions of intestinal microflora and mucosal structure were exhibited. Transforming growth factor-ß1 activated IgA CSR as evidenced by the increased activation molecules and IgA precursors. Strikingly, TGF-ß1 improved intestinal mucosal IgA dysfunction, dysbiosis and epithelial damage at the early stage after reperfusion. In addition, SB-431542, a specific inhibitor of activating mothers against decapentaplegic homologue (SMAD) 2/3, totally blocked the inductive effect of TGF-ß1 on IgA CSR and almost abrogated the above protective effects on intestinal barriers. Taken together, our study demonstrates that TGF-ß1 protects intestinal mucosal IgA immunity, microbiota and epithelial integrity against I/R injury mainly through TGF-ß receptor 1/SMAD 2/3 pathway. Induction of IgA CSR may be involved in the protection conferred by TGF-ß1.

Remifentanil preconditioning protects the small intestine against ischemia/reperfusion injury via intestinal δ- and µ-opioid receptors.

BACKGROUND: Intestinal ischemia/reperfusion (I/R) injury can cause a high rate of mortality in the perioperative period. Remifentanil has been reported to provide protection for organs against I/R injury. We hypothesized that remifentanil preconditioning would attenuate the small intestinal injury induced by intestinal I/R. METHODS: We used both an in vivo rat model of intestinal I/R injury and a cell culture model using IEC-6 cells (the rat intestinal epithelial cell line) subjected to oxygen and glucose deprivation (OGD). Remifentanil was administered before ischemia or OGD, and 3 specific opioid receptors antagonists, naltrindole (a δ-OR selective antagonist), nor-binaltorphimine (nor-BNI, a κ-OR selective antagonist), and CTOP (a µ-OR selective antagonist), were administered before preconditioning to determine the role of opioid receptors in the intestinal protection mediated by remifentanil. RESULTS: In the in vivo rat model, intestinal I/R induced obvious intestinal injury as evidenced by increases in the Chiu score, serum diamine oxidase activity, the apoptosis index, and the level of cleaved caspase-3 protein expression, whereas remifentanil preconditioning significantly improved these changes in vivo. In the in vitro cell culture exposed to OGD, cell viability (MTT, ie, (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay and flow cytometric analysis showed that remifentanil preconditioning enhanced IEC-6 cell viability and decreased apoptosis. In both in vitro and in vivo models, the aforementioned protective effects of remifentanil preconditioning were abolished completely by previous administration of the δ- or µ-opioid markedly attentuated but not the κ-opioid receptor antagonist. CONCLUSION: Remifentanil preconditioning appears to act via δ- and µ-opioid receptors to protect the small intestine from intestinal I/R injury by attenuating apoptosis of the intestinal mucosal epithelial cells.

Decreased PD-1/PD-L1 Expression Is Associated with the Reduction in Mucosal Immunoglobulin A in Mice with Intestinal Ischemia Reperfusion.

BACKGROUND: Intestinal ischemia/reperfusion (I/R) disrupts intestinal mucosal integrity and immunoglobulin A (IgA) generation. It has recently been shown that the programmed cell death-1 receptor (PD-1) plays a crucial role in regulating intestinal secreted IgA (sIgA). AIMS: To evaluate changes in PD-1 and PD-ligand 1 (PD-L1) expression on Peyer's patches (PP) CD4(+) T cells and to investigate the correlation between PD-1/PD-L1 and intestinal IgA production/mucosal integrity in mice following intestinal I/R. METHODS: I/R injury was induced by clamping the superior mesenteric artery for 1 h followed by 2-h reperfusion. PD-1/PD-L1 expression on PP CD4(+) T cells was measured in I/R and sham-operated mice. Additionally, transforming growth factor-ß1 (TGF-ß1) and interleukin-21 (IL-21) mRNA in CD4(+) T cells and IgA(+) and IgM(+) in PP B cells, as well as intestinal mucosal injury and sIgA levels, were assessed. RESULTS: PD-1/PD-L1, TGF-ß1, and IL-21 expression was down-regulated after intestinal I/R. Furthermore, IgA(+) B cells decreased and IgM(+) B cells increased in mice with intestinal I/R. Importantly, decreased PD-1/PD-L1 expression was correlated with increased mucosal injury and decreased IgA levels, as well as with decreased TGF-ß1 and IL-21 expression. CONCLUSIONS: Intestinal I/R inhibits PD-1/PD-L1 expression on PP CD4(+) T cells, which was associated with an impaired intestinal immune system and mechanical barriers. Our study indicates that PD-1/PD-L1 expression on CD4(+) T cells may be involved in the pathogenesis of intestinal I/R injury.

Treatment with Recombinant Trichinella spiralis Cathepsin B-like Protein Ameliorates Intestinal Ischemia/Reperfusion Injury in Mice by Promoting a Switch from M1 to M2 Macrophages.

Intestinal ischemia/reperfusion (I/R) injury, in which macrophages play a key role, can cause high morbidity and mortality. The switch from classically (M1) to alternatively (M2) activated macrophages, which is dependent on the activation of STAT6 signaling, has been shown to protect organs from I/R injuries. In the current study, the effects of recombinant Trichinella spiralis cathepsin B-like protein (rTsCPB) on intestinal I/R injury and the potential mechanism related to macrophage phenotypes switch were investigated. In a mouse I/R model undergoing 60-min intestinal ischemia followed by 2-h or 7-d reperfusion, we demonstrated that intestinal I/R caused significant intestinal injury and induced a switch from M2 to M1 macrophages, evidenced by a decrease in levels of M2 markers (arginase-1 and found in inflammatory zone protein), an increase in levels of M1 markers (inducible NO synthase and CCR7), and a decrease in the ratio of M2/M1 macrophages. RTsCPB reversed intestinal I/R-induced M2-M1 transition and promoted M1-M2 phenotype switch evidenced by a significant decrease in M1 markers, an increase in M2 markers, and the ratio of M2/M1 macrophages. Meanwhile, rTsCPB significantly ameliorated intestinal injury and improved intestinal function and survival rate of animals, accompanied by a decrease in neutrophil infiltration and an increase in cell proliferation in the intestine. However, a selective STAT6 inhibitor, AS1517499, reversed the protective effects of rTsCPB by inhibiting M1 to M2 transition. These findings suggest that intestinal I/R injury causes a switch from M2 to M1 macrophages and that rTsCPB ameliorates intestinal injury by promoting STAT6-dependent M1 to M2 transition.

Capsule endoscopy in diagnosis of small bowel diseases: a health technology assessment.

OBJECTIVES: Capsule endoscopy (CE) has been widely used in the diagnosis of small bowel disease (SBD) in the world. To bring CE into the national health insurance directory, and intensify its popularization in primary hospital, the government needs high-quality HTA evidence for decision makers. We were appointed by the National Health and Family Planning Commission of China to evaluate the effectiveness, safety, economy, and applicability of CE in the diagnosis of SBD, to provide the best currently available evidence for decision making. METHODS: We searched the Cochrane Library (Issue 8, 2013), PubMed, EMbase, INAHTA, VIP, CBM, CNKI and WanFang Data. All confirmed or suspected SBD patients with diagnosis by CE versus other alternative therapies were considered. Health technology assessments (HTAs), systematic reviews (SRs), meta-analyses, randomized controlled trials (RCTs), guidelines and economic studies were included. Two investigators selected studies, assessed the quality and extracted data independently, and a descriptive analysis was used. RESULTS: We included 4 HTAs, 11 SRs/meta-analyses, 2 RCTs, 5 guidelines, and 10 economic studies for assessment. The results showed that the disease detection rate of CE was higher than that of many other traditional technologies and that the main adverse event for CE was retention (0.7% to 3.0%). These results were consistent with those of the guidelines. Comprehensive results of economic studies showed the superiority of CE compared with other technologies. As the first choice, CE can decrease potential costs, especially when used in outpatients. CONCLUSIONS: (i) CE has advantages in diagnostic yield, safety, and cost in the diagnosis of SBD, but some limitations exist. It still needs more high-quality evidence on CE diagnosis accuracy. (ii) When the government approves the introduction of CE in a hospital, many factors must be considered, such as the local disease burden, clinical demand, ability to pay, and staff. At the same time, it is necessary to standardize training for operating physicians, to reduce economic losses caused by poor technical ability of the medical staff.

Helical tomotherapy for cancer treatment: a rapid health technology assessment.

OBJECTIVES: Helical tomotherapy (HT) can be applied to treat complex malignant cancer with high-precise radiotherapy, and it can reduce the damage to normal tissues and improve treatment effects. But the procurement of HT must be approved by relevant departments of administration affairs. This study, appointed by the National Health and Family Planning Commission of China and undertook by the National Health Development Research Center and the Chinese Evidence-Based Medicine Centre, was aimed to rapidly assess the effectiveness, safety, costs, and applicability of HT, so as to provide currently available best evidence for decision-makers of health policies. METHODS: We electronically searched databases including PubMed, EMbase, The Cochrane Library, CNKI, WanFang Data, VIP, CBM, and other professional websites. Two reviewer independently screened literature according to the inclusion and exclusion criteria, extracted data, assessed quality, and then performed descriptive analysis. RESULTS: (i) We finally included 150 studies, encompassing 5 HTAs, 18 CCTs, and 127 observational studies. (ii) The included HTAs were published during 2006-2009, providing fairly less evidence of low quality and the results of 145 primary studies showed that: HT had been used mainly in the treatments of 14 kinds of cancer, with low total toxicity and high survival rates. Although the quality of the included studies was poor, there was much evidence about prostate cancer, head and neck cancer, nasopharynx cancer, cervical cancer, lung cancer and liver cancer, with enough sample and fairly reliable results in HT efficacy and safety. And (iii) a total of 56 clinical trials were registered in Clinicaltrials.gov, most of which were registered by the occident. Among them, 9 were completed but the results had not been published yet. CONCLUSIONS: The evidence of this study showed that, HT is safe and effective in clinic. But the abovementioned conclusion needs to be verified by conducting more high-quality studies with long-term follow-up. The costs of HT in procurement, maintenance, and application are high; and the skills, training, and qualification of operators are required. We suggest that the procurement of HT should be reduced; it should be allocated rationally and effectively used after comprehensive assessment in China's cancer epidemiology characteristics, health resource allocation, disease burden, medical service level, etc.; and also high-quality studies with long-term follow-up should be financially supported on the basis of establishing projects, so as to provide local evidence and consistently guide and improve scientific decision-making.
