China's growing contribution to military Chinese medicine (2005-2014): a ten-year literature survey.

OBJECTIVE: In China, people have relied on traditional Chinese medicine (TCM) for thousands of years to keep healthy and treat diseases. TCM also plays an important role in military health services and now forms a new discipline called military Chinese medicine (MCM). However, the type, quality and focus of research articles about MCM have not been reported. The present study was performed to analyze the growing trends of MCM and investigate China's contribution to military health services. METHODS: China's MCM publications were retrieved from the PubMed database, as well as China National Knowledge Infrastructure, Wanfang Data and Chongqing VIP database from 2005 to 2014. RESULTS: The study found that the number of published articles increased markedly from 2005 to 2014. Basic research studies comprised a small percentage of the literature. Among these studies, military training injury and special military environmental medicine were the most common research subjects in MCM. Military hospitals were the main institutions generating MCM literature. CONCLUSION: The quality of MCM research is generally low, as indicated by the proportion of publications in core journals. Studies on MCM still lack high-quality publications and international cooperation.

A case report of gastric cancer with brain metastasis: Rare peripheral nervous system symptoms.

Gastric cancer with brain metastasis is rare. The present study reports a case of gastric cancer with isolated brain metastasis 1 year after gastrectomy. To the best of our knowledge, there have been no prior reports of solitary brain metastasis from gastric cancer with peripheral nervous system symptoms. A distal gastrectomy was performed on a 60-year-old male patient with gastric cancer in November 2012. Postoperative pathological analysis revealed a moderately differentiated adenocarcinoma with tumor invasion into the serosa and metastasis to one dissected lymph node. No abnormalities were found at follow-up examination. However, a tumor representing metastasis to the brain was recognized by a cranial enhanced magnetic resonance imaging examination 1 year after gastrectomy, which was performed when the patient exhibited numbness and thigmesthesia. The patient was administered 30 Gy of stereotactic radiotherapy, delivered in 5 fractions. The patient succumbed to disease 10 months subsequent to undergoing radiotherapy. This case report suggests that gastric cancer may re-present as brain metastasis with peripheral nervous system symptoms.

How do systematic reviews of acupuncture for pain relief incorporate risk of bias assessments into the synthesis? A methodological study.

OBJECTIVE: By reviewing the assessment of internal validity in relevant systematic reviews (SRs), the aim of this study was to identify how critical appraisals of risk of bias (RoB) inform the synthesis of evidence in SRs of acupuncture for pain relief. METHODS: SRs were searched in Medline, EMBASE, and the Cochrane Database of SRs from their inception to 30 December 2014. Only SRs of acupuncture for pain relief were included. Basic information, types of RoB appraisal tool, whether or not there was domain-level assessment of RoB, whether or not the reviews ranked studies by RoB, plus whether or not (and, if so, how) RoB appraisal was incorporated into the synthesis were determined. RESULTS: A total of 91 SRs met the inclusion criteria and were included in the final analysis. Over half of the SRs (85, 64.8%) used standard tools, such as the Jadad quality score and the Cochrane RoB tool, followed by adapted tools (n=23, 25.3%). Of the 85 SRs that assessed RoB, 29 (34.1%) presented domain-level assessment and 71 SRs (83.5%) included ranking of the studies based on RoB assessment. Of these 71, 35 (49.4%) used a cut-off threshold score and 26 (36.6%) required all criteria sum-up. Of the 85 SRs that assessed RoB, 48 (56.5%) incorporated RoB appraisal into the data synthesis. CONCLUSIONS: Although most SRs of acupuncture for pain relief conducted some form of RoB assessment, nearly half of them failed to incorporate the RoB assessment into the synthesis.

The application status of Chinese herbal medicine in military health service in China.

Military medicine has had a long history in China since the emergence of the war. Chinese medicine, especially Chinese herbs, was widely used in China as well as other Asian countries for the prevention and treatment of diseases in the military for hundreds of years. However, the use of Chinese medicine in military health service has never been well studied. In this article, we briefly summarize the application status of Chinese herbal medicine in military health service in China, putting particular emphasis on special military environment, in an attempt to build a bridge between Chinese medicine and military health service and promote the quality of health service for the military and maintain world peace.

Comparison of registered and published primary outcomes in randomized controlled trials of gastroenterology and hepatology.

OBJECTIVES. The need for trial registration as well as the benefits it has brought for the transparency of medical research has been recognized for years. Trial registration has turned from an exception to a mandatory guideline in recent years. The present study aimed to examine the characteristics of registered randomized controlled trials (RCTs) in a sample of recently published gastroenterology RCTs, and to assess the consistency of registered and published primary outcome (PO) in RCTs. METHODS. Articles published in the top five "general and internal journals" and top five "gastroenterology and hepatology journals" categories between 2009 and 2012 were searched in PubMed. Basic characteristics and the registration information were identified and extracted from the included RCTs. PO consistency analysis was conducted to compare between the registered and published format. RESULTS. A total of 305 RCTs were included; among them 252 could be identified with a registration number. Nearly half of these RCTs were funded solely by industry (141/305, 46.3%). ClinicalTrials.gov was the most popular registry for these RCTs (214/252, 84.9%). A total of 155 RCTs were included in the PO consistency analysis. Among them, 22 (14.2%) RCTs had discrepancies between POs registered in the trial registry compared to the published article. CONCLUSIONS. Based on the results of the present study, selective outcome reporting of gastroenterology RCTs published in leading medical journals has been much improved over the past years. However, there might be a sampling bias to say that consistency of registered and published POs of gastroenterology RCTs has been better than before.
