Effect of integrated Chinese and Western medicine therapy on severe hand, foot and mouth disease: A prospective, randomized, controlled trial.

OBJECTIVE: To evaluate the efficacy and safety of Chinese medicine (CM) plus Western medicine (WM) in the treatment of pediatric patients with severe hand, foot and mouth disease (HFMD) by conducting a prospective, controlled, and randomized trial. METHODS: A total of 451 pediatric patients with severe HFMD were randomly assigned to receive WM therapy alone (224 cases, WM therapy group) or CM [Reduning Injection ( ) or Xiyanping Injection ()] plus WM therapy (227 cases, CM plus WM therapy group) for 7-10 days, according to a web-based randomization system. The primary outcome was fever clearance time, which was presented as temperature decreased half-life time. The secondary outcomes included the rate of rash/herpes disappearance within 120 h, as well as the rate for cough, runny nose, lethargy and weakness, agitation or irritability, and vomiting clearance within 120 h. The drug-related adverse events were also recorded. RESULTS: The temperature decreased half-life time was 40.4 h in the WM therapy group, significantly longer than 27.2 h in the CM plus WM therapy group (P<0.01). Moreover, the rate for rash/herpes disappearance within 120 h was 43.6% (99/227) in the CM plus WM therapy group, significantly higher than 29.5% (66/224) in the WM therapy group (P<0.01). In addition, the rate for cough, lethargy and weakness, agitation or irritability disappearance within 120 h was 32.6% (74/227) in the CM plus WM therapy group, significantly higher than 19.2% (43/224) in the WM therapy group (P<0.01). No drug-related adverse events were observed during the course of the study. CONCLUSION: The combined CM and WM therapy achieved a better therapeutic efficacy in treating severe HFMD than the WM therapy alone. Reduning or Xiyanping Injections may become an important complementary therapy to WM for relieving the symptoms of severe HFMD. (Registration No. NCT01145664).

Use of a full-body digital X-ray imaging system in acute medical emergencies: a systematic review.

BACKGROUND: To evaluate the available evidence for the clinical effectiveness and biohazard safety of a full-body digital X-ray imaging system (Lodox) in acute medical emergencies. METHODS: Electronic databases (including PubMed, Embase and the Cochrane Library; up to January 2014) and reference lists of articles were searched. The quality of the included studies was determined, and a narrative assessment was undertaken. RESULTS: A total of 256 articles were reviewed. Fifteen clinical studies and eight case series met the eligibility criteria. All 23 studies reporting use of a full-body X-ray imaging system in acute medical emergencies on Lodox. Based on figures in six studies comprising various evaluation methods, image quality of Lodox was mostly comparable to that of conventional X-rays and the radiation dose was considerably lower. Lodox demonstrated a sensitivity ranging from 62% to 73%, and a specificity ranging from 99% to 100% compared with CT for the evaluation of emergency patients with polytrauma, which is similar to that of conventional X-rays. Examination time using Lodox ranged from 3.5  to 13.9 min compared with 8 to 25.7 min using conventional X-rays. However, there was no evidence it significantly shortened resuscitation time or emergency department length of stay. Publication bias might have occurred; some published studies might have been influenced by conflicts of interest. CONCLUSIONS: The Lodox machine is capable of rapidly scanning the entire body and offers an equivalent diagnostic assessment tool compared with conventional X-rays. It seems to have the potential to reduce cumulative radiation dosage for emergency patients compared with conventional X-rays. Application of Lodox might be helpful to reduce resource use and simplify care in lower-resourced areas.

Effect of Hyperbaric Oxygen on the Growth of Intracranial Glioma in Rats.

BACKGROUND: Numerous studies have confirmed that hyperbaric oxygen (HBO) in combination with radiotherapy or chemotherapy may increase the efficacy of radiotherapy or chemotherapy in patients with glioma. However, whether HBO therapy alone may inhibit or promote the growth of malignant tumors remains controversial. This study aimed to investigate the effect of HBO on the growth of glioma in rats, and the impact of HBO on the expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1-alpha (HIF-1α), angiogenesis, and apoptosis of glioma cells. METHODS: Male Sprague-Dawley rats were treated with or without HBO after glioma cell inoculation and followed for up to 16 days postinoculation. Rats were randomized to receive bilateral forelimb function tests (n = 20 per group) and head magnetic resonance imaging (n = 5 per group). Differences between HBO and control groups were tested using 2-sample independent t-tests and changes over time within treatment groups were analyzed using a repeated measurement analysis of variance with Bonferroni correction. The effect of HBO on the expression of VEGF, HIF-1α, von Willebrand factor, angiogenesis, and tumor cell apoptosis were also examined (n = 5 per group). RESULTS: Forelimb function scores were reduced in both HBO-treated and control groups. HBO-treated rats had significantly larger tumor volume and more water in the cerebellum compared with control rats. The intratumoral expression of VEGF was significantly higher in HBO-treated rats compared with control rats (23.2% vs. 13.3%, P = 0.002). HIF-1α was significantly increased in HBO-treated rats compared with controls in the expression of both intratumoral (72.7% vs. 54.9%, P = 0.001) and peritumoral (2.6% vs. 1.9%, P = 0.003) cells. The intratumoral microvessel density (MVD) was significantly higher in the HBO group (15.6 vessels/field vs. 4.4 vessels/field, P < 0.001), and the peritumoral MVD was not significantly different between the two groups (P > 0.05). Apoptosis was significantly lower in HBO-treated rats compared with controls (44.4% vs. 82.8% for intratumoral; 10.1% vs. 77.5% for peritumoral, both P < 0.001). CONCLUSIONS: The current results demonstrate that HBO alone may promote tumor growth, and is therefore not suitable to treat patients with gliomas with neurological deficits or disorders with HBO alone. If HBO must be used as a mean of rehabilitation, it is recommended that HBO should be combined with radiotherapy or chemotherapy.

Radiotherapy after hyperbaric oxygenation in malignant gliomas.

OBJECTIVE: This review was to evaluate the efficacy and toxicity of radiation therapy (RT) administered immediately after hyperbaric oxygen (HBO) therapy in patients with high grade gliomas. RESEARCH DESIGN AND METHODS: PubMed, Embase, ISI Web of Knowledge, and Cochrane databases were searched using combinations of the following search terms: radiotherapy, hyperbaric oxygenation, chemotherapy, glioma, brain tumor. Selection was limited to prospective studies involving patients given HBO followed by RT for high-grade gliomas. Data extracted from studies included the clinical research phase of the study, number of study arms, number of patients, patient age and gender, glioma type and grade, pressure and length of HBO, protocol of radiation therapy, duration of follow-up, and the outcomes. MAIN OUTCOME MEASURES: Overall survival, time to progression, response rate, tumor regression, and toxic effects associated with HBO plus RT treatment. RESULTS: Literature search/screening yielded eight studies for analysis. Six of the studies were single-arm in design and enrolled a total of 203 patients, of whom 142 had grade IV gliomas and 61 had grade III gliomas. In these six studies, all patients received HBO then RT. Two studies were double-arm in design, with 24 patients treated with HBO followed by RT and 26 patients treated with RT alone. The findings from both the single- and double-arm studies indicated improved outcomes (survival rate, progression free survival, time to progression, response rate) with HBO and RT therapy. Reported toxicity included leucopenia, anemia, thrombocytopenia, fever, loss of appetite, constipation, nausea, vomiting, and liver dysfunction. The addition of HBO had minimal effect on toxicity or side effects; across the eight studies, only one patient with severe middle ear barotrauma had a complication directly related to HBO exposure. CONCLUSION: This systematic reviews suggests that the addition of HBO to RT is tolerated and may be beneficial in patients with high-grade gliomas.
