ABSTRACT

Except the complete literature of , Tianhui medical slips unearthed in Chengdu also include a part of literature document on meridian, which was seriously damaged. Both of them were found in the same box together with . The title of the document chapter was not found in the residual medical slips. By investigated the textual content, it was discovered that such medical slips were different from the Mawangdui silk books, i.e. and , of Zhangjiashan bamboo slips of Han Dynasty, as well as in Tianhui medical slips. But, the sentences in description are similar to the sentences of in (), therefore, this residual slips was named as () by the collator. In the paper, by the comparison of this residual slip chapter with the unearthed literature document on meridian as well as in , the origin and evolution of meridian theory of traditional Chinese medicine in the Qin and Han dynasties were explained. By taking it as an example, the construction process of classical theory of traditional Chinese medicine was explored.

ABSTRACT

Among the medical texts excavated in 2012-2013 from the Han Dynasty tomb at Tianhui township in Sichuan province, we found a collection on the treatment of 60 ailments. Under each ailment, we found one or more formulas, for a total of 106 formulas. The authors of this paper compiled and analyzed these texts based on the original bamboo slips and named this collection with the title Methods for Blending Decoctions to Treat 60 Ailments because the content was focused on blending and making medicinal formulas, and also due to the historical connections with the texts the Record of the Court Scribe, "Biography of Bian Que and Cang Gong". For these reasons, this title was determined, where "blending decoctions" mean "blending and harmonizing medicines optimally in preparation for decocting". The Tianhui texts preserve ancient forms of medicinal formulas, including some once believed to be lost, such as "grain decoctions", "fermented alcohol decoctions", and "fiery decoctions". Based on the historical evidence, we can now ascertain that this text is the "Blending Formulas and Making Decoctions" mentioned in the Record of the Court Scribe written by Cang Gong. Moreover, the medical texts, Canon Formulas in Decoction Form (from the book of Han Dynasty) and the Imperial Pharmacy Formulas to Benefit the People in Song Dynasty are both of this genre of medical literature. The Tianhui text is therefore a representative of this genre of literature in the Western and eastern Han, acting as a key link between early medical formula books and later formula books.

ABSTRACT

Objective To investigate the application of SIEMENS Ysio DR amplification in the radiation dose reduction. Methods Totally 160 patients with similar heights and body shapes were divided equally into A,B,C and D groups,and then underwent radiological examinations with SIEMENS Ysio DR from September 2014 to May 2016.A and B groups went through right hand AP oblique examination with the same kV while different mAs, and C and D groups had chest posteroanterior examination with different kV and the same mAs. Image quality was regulated with the amplification coefficient, and then evaluated with double-blind method by two senior radiologists.Statistical analysis was executed over the values of mAs in A and B groups and those of kV in C and D groups. Results A group had the mAs value being(2.26 ±0.16)mAs, which was significantly different from that of B group [(4.05±0.19)mAs] (P<0.05);while C group had kV value being (104.79±6.39)kV, which was statistically different from that of D group [(83.48±3.67)kV] (P<0.05). Satisfactory image were obtained by regulation with amplication coefficient.There was no obvious difference between the image quality in either A and B groups or C and D groups(P>0.05).Based on the principle that low mAs resulted in low radiation dose and high kV lead to low effective dose,A group had the radiation dose lower than those of B group,and C group had the effective dose lower than those of D group. Conclusion SIEMENS Ysio DR has the photographing parameters regulated according to different sites and the amplification coefficient for enhancing image quality, which decreases X-ray radiation dose and effective dosage with the diagnosis results unaffected.

ABSTRACT

<p><b>OBJECTIVE</b>Our objective was to systematically evaluate chemotherapy-based control of ascariasis and hookworm infection and make predictions of the effectiveness of repeated mass treatment at different levels of coverage in highly endemic areas of China.</p><p><b>METHODS</b>Field surveys were carried out to acquire the ascariasis and hookworm prevalence and intensity (mean worm burden) at baseline, one month and one year later. We calculated model parameters based on the survey data, then incorporated them into a quantitative framework to predict the prevalence and intensity one year later. Sensitivity analyses were performed to assess the influence of the chemotherapy measures on prevalence and intensity, and model simulations were performed to evaluate the feasibility of achieving the proposed transmission control criteria under different chemotherapy measures.</p><p><b>RESULTS</b>The predicted prevalence and intensity one year from baseline were within the 95% confidence interval of actual values. As treatment frequency or coverage increased, the prevalence and intensity decreased. Model simulations show that many rounds of treatment are needed to maintain the prevalence at a low level in highly endemic areas of China.</p><p><b>CONCLUSION</b>We should select different combinations of treatment frequency, coverage and drug efficacy according to available resources and practical attainable conditions. Mathematical modeling could be used to help optimize the chemotherapeutic scheme aiming at specific parasitic species and areas, and to direct the establishment of soil-transmitted helminthiasis control criteria in China.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the long-term influence of vertebral fixation through or across the affected vertebra on vertebral morphology.</p><p><b>METHODS</b>Clinical data of 48 patients with simple thoracic and lumbar spinal fractures who were admitted between Jan. 2008 and Dec. 2010 were analyzed retrospectively. Among them 36 cases (28 males and 8 females) were fixed through the injured vertebra (group A) and 12 cases (8 males and 4 females) were fixed across the injured vertebra (group B). All patients were followed up for 6-36 months (mean 11.5 months). The vertebral body height, endplate angle and neurofunction were compared between the two groups before surgery, a week after surgery and at the end of the follow-up period.</p><p><b>RESULTS</b>There was no statistically significant difference in vertebral body height,endplate angle and neurofunction before operation between group A and B (P > 0.05). Vertebral body height and endplate angle improved in both groups a week after operation and at the end of the follow-up period as compared with those before operation (P < 0.05), and the efficacy in group B was significantly better than that in group A (P < 0.05). There was no significant difference in neurofunction between the two groups (P > 0.05).</p><p><b>CONCLUSION</b>The fixation method through the injured vertebra had a better reduction effect, more stable fixation, and a better long-term effect on vertebral morphology than that across the injured vertebra in the treatment of thoracolumbar vertebral fractures.</p>

ABSTRACT

By comprehensively reviewing the origin and history of Niuhuang Jiedu Wan and its "derivatives", we studied the clinical records of realgar, investigated its clinical usage, dosage, efficacy, and toxicity in the literatures. We pinpointed the factors that might be associated with safety problems of Niuhuang Jiedu Pian (Wan) and other traditional Chinese medicine (TCM) preparations containing arsenic substances. In this article we also put forward suggestions for strengthening the surveillance and administration of similar TCM preparations.
