Huntington's like conditions in China, A review of published Chinese cases

Background: Knowledge about HD in China is lacking in the international literature. We have therefore analyzed the Chinese literature to thoroughly explore the clinical characteristics of Huntington disease in China. Methods: A computer-based online search of China National Knowledge Infrastructure was performed to review case reports concerning HD published between January 1980 and April of 2011, and the clinical characteristics were extracted. Results: A total of 92 studies involving 279 patients (157 males and 122 females) were collected, 82.0% of which were from provinces of North China. Most of the cases (97.8%) had a family history of HD, and paternal inheritance (65.5%) was higher than maternal inheritance (34.5%). Onset age was 35.8 (± 11.8) years, death occurred with 45.6 (± 13.5) years after a course of 11.6 (± 5.6) years. Involuntary movements were the most frequent reported presentation (found in 52.3%, including 64.4% in the entire body, 19.8% in the upper limbs, and 13.7% in the head and face). Psychiatric symptoms at onset were reported in 16.1%, and cognitive impairment in 1.8%. With disease progression, 99.6% of patients had abnormal movements, 67.9% cognitive impairment, and 35.0% suffered psychiatric symptoms. Of the reported patients, only 22 underwent IT15 gene testing with positive results. Conclusion: HD is a well-reported entity in Chinese medical literature, however, only a small number of instances have been proven by molecular diagnosis. Most of the features resemble what is known in other countries. The highly predominant motor presentation, and the higher male prevalence as well as the apparent concentration in Northern China may be due to observational bias. There is therefore a need to prospectively examine cohorts of patients with appropriate comprehensive assessment tools including genetic testing.

The ocular motor features of adult-onset alexander disease: a case and review of the literature

A 51-year-old Chinese man presented with gaze-evoked nystagmus, impaired smooth pursuit and vestibular ocular reflex cancellation, and saccadic dysmetria, along with a family history suggestive of late-onset autosomal dominant parkinsonism. MRI revealed abnormalities of the medulla and cervical spinal cord typical of adult-onset Alexander disease, and genetic testing showed homozygosity for the p.D295N polymorphic allele in the gene encoding the glial fibrillary acidic protein. A review of the literature shows that ocular signs are frequent in adult-onset Alexander disease, most commonly gaze-evoked nystagmus, pendular nystagmus, and/or oculopalatal myoclonus, and less commonly ptosis, miosis, and saccadic dysmetria. These signs are consistent with the propensity of adult-onset Alexander disease to cause medullary abnormalities on neuroimaging.

Traditional chinese medicine (phytotherapy): health technology assessment report - selected aspects

Objective: A summary of main aspects from a Health Technology Assessment report on Traditional Chinese Medicine (TCM) in Switzerland concerning effectiveness and safety is given. Materials and Methods: Literature search was performed through 13 databases, by scanning reference lists of articles and by contacting experts. Assessed were quality of documentation, internal and external validity. Results: Effectiveness: 43 articles concerning 'gastrointestinal tract and liver' were assessed. The studies covering 7,436 patients were undertaken in China (35), Japan (3), USA (2) and Australia (3); 33/43 being controlled studies. 34/40 show significantly better results in the TCM-treated group. A comparison of studies on results of treatment based on a diagnosis according to TCM criteria and studies on results of treatment according to Western diagnosis shows that treatment based on TCM diagnosis improves the result. The comparison of treatment by individual medication and standard medication showed a trend in favor of individual medication. Safety: TCM training and practice for physicians in Switzerland are officially regulated. Side effects occur, but no severe effects have been registered up to now in Switzerland. TCM medicinals are imported; admission regulations are being installed. Problems due to production abroad, Internet trade, self-medication or admixtures are possible. Conclusion: The evaluation of the literature search provides evidence for a basic clinical effectiveness of TCM therapy. Severe side effects were not observed in Switzerland. Regulations for trading and use of medicinals prevent treatment risks. Further clinical studies in a Western context are required.

The Rasikajy civilization in northeast Madagascar: a pre-European Chinese community?

Archaeological excavations in northern Madagascar during the first half of the 20th century have revealed the presence of a former prosperous civilisation known as the Rasikajy civilisation. Little is known about the origin of this civilisation and how and when they first arrived in Madagascar. The most striking evidence for the Rasikajy civilisation comes from excavations at a necropolis in Vohemar located along the northeast coast, where more than 600 tombs containing spectacular objects were unearthed in the 1940s (Vernier & Millot 1971). The findings in the tombs included, amongst others, Chinese ceramics, silver and gold jewellery, iron weapons, glassware, bronze mirrors and chlorite-schist objects (ibid.). The latter objects were produced from chlorite schist mined at quarries in northern and eastern Madagascar and there is evidence that jewellery and iron objects were also produced by the Rasikajy from locally available raw material. Chlorite-schist objects have not only been found in coastal sites in Madagascar, but also in the Comores and eastern Africa suggesting an active engagement of the Rasikajy in western Indian Ocean trade. Our re-evaluation of published literature on archaeological sites in northern Madagascar indicates that the majority of Chinese ceramics found in the tombs at Vohemar dates from the 15th and first half of the 16th century with some dating back to the 14th century or earlier. Our comparative analysis of burial objects at Vohemar shows that locally produced chlorite-schist tripod vessels exhibit remarkable resemblances to ancient Chinese bronze ritual tripod vessels. The objects encountered in the tombs and their positions with respect to the body indicate that the Rasikajy practiced burial rites similar to those practised in the past in China. Our re-evaluation of the literature suggests that communities with Chinese roots were present in northeastern Madagascar prior to the arrival of the first Europeans in 1500 and participated in the Indian Ocean trade network. The demise of the Rasikajy civilisation seems to have occurred in the second half of the 16th century when production of chlorite-schist objects ceased. It is still unclear why this occurred.
