Evidence mapping of clinical research on 28 Chinese patent medicines for tension-type headache / 中国中药杂志

In this study, the evidence mapping methodology was used to systematically retrieve and sort out the clinical research evidence of Chinese patent medicines in the treatment of tension-type headache(TTH), and to understand the distribution of evidence in this field and the basis and quality of evidence. Chinese and English articles on the 28 Chinese patent medicines for TTH, which were recorded in National Essential Medicines List(2018), Medicine Catalogue for National Basic Medical Insurance, Work Injury Insurance, and Maternity Insurance(2020), and Chinese Pharmacopoeia(2020), were retrieved from China National Knowledge Infrastructure(CNKI), Wanfang, VIP, China Biology Medicine disc(CBMdisc), PubMed, EMbase, and Cochrane Library from the establishment to June 2021, followed by descriptive analysis. Then, tables and bubble charts were plotted to analyze the distribution characteristics of evidence. A total of 129 eligible articles were yielded: 126 randomized/non-randomized controlled trials, and 3 systematic reviews. The functions, indications, and composition of the 28 medicines, as well as the proportion of related articles, publication trends, intervention measures, and outcome indicators were compared and analyzed. The results showed that the 28 Chinese patent medicines, composed of 128 Chinese medicinals, can be classified into six categories in terms of function: reinforcing healthy Qi, tranquilizing mind, dispelling stasis, regulating Qi, treating wind, and resuscitating. There are ongoing efforts to study the treatment of TTH with Chinese patent medicine in China, despite of little evidence. The clinical positioning of Chinese patent medicine for TTH is not clear, and clinical research fails to highlight the advantages of Chinese medicine. In addition, the outcome indicators have not been standardized and unified, and there is a lack of evidence on the long-term efficacy of Chinese patent medicine for TTH. This study is the first exploratory application of evidence maps to compare the characteristics and clinical research progress of 28 Chinese patent medicines for TTH, which can provide a reference for research on the optimization of Chinese medicine strategies for TTH.

Impacts of acupuncture on blood pressure and hematoma in patients of cerebral hemorrhage at the early stage / 中国针灸

<p><b>OBJECTIVE</b>To explore the therapeutic effect of acupuncture for hypertensive cerebral hemorrhage at the early stage.</p><p><b>METHODS</b>Fifty-four cases of small-amount cerebral hemorrhage were randomized into an acupuncture group and a conventional treatment group, 27 cases in each one. In the conventional treatment group, special care, oxygen therapy, nerve nutrition and symptomatic support were applied. In necessary, dehydrant and hypotensive drugs were prescribed for antihypertension, or surgery was given. In the acupuncture group, on the basis of the treatment as the control group, acupuncture was applied at Quchi (LI 11), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3). Acupuncture was given at the admission, 4 h, 6 h and 12 h after disease onset respectively. Blood pressure was monitored in the whole procedure. 6 h and 24 h after disease onset, the cranial CT was re-examined. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), hematoma volume and neurological deficit score were compared at different time points between the two groups.</p><p><b>RESULTS</b>(1) Blood pressure: from the admission to 12 h after disease onset, SBP, DBP and MAP were increased apparently in the conventional treatment group and increased slightly in the acupuncture group. The differences in SBP [(164.3 +/- 21.6) mmHg vs (158.6 +/- 21.5) mmHg] and MAP [(113.4 +/- 4.9) mmHg vs (106.7 +/- 6.1) mmHg] were significant between the two groups (both P < 0.05). From 12 h to 24 h after disease onset, compared with the conventional treatment group, SBP and MAP were decreased apparently in the acupuncture group [(147.3 +/- 21.6) mmHg vs (158.4 +/- 23.5) mmHg, (97.2 +/- 5.3) mmHg vs (106.6 +/- 5.1) mmHg, both P < 0.05)]. (2) Hematoma volume: from the admission to 6 h after disease onset, the volume was increased by (4.15 +/- 0.73) mL in the convertional treatment group and (2.67 +/- 0.33) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). From the admission to 24 h after disease onset, it was increased by (5.57 +/- 1.26) mL in the convertional treatment group and (3.14 +/- 1.18) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). (3) Neurological deficit score: the score was increasing gradually in first 3 days after disease onset in the two groups. The score (38.39 +/- 6.84) in the acupuncture group on the first day was different significantly as compared with that (42.37 +/- 7.46) in the conventional treatment group (P < 0.05). On the 10th days, the score (24.68 +/- 5.42) in the acupuncture group was different significantly from that (29.74 +/- 7.36) in the convertional treatment group (P < 0.05).</p><p><b>CONCLUSION</b>There is no peak of blood pressure rising, and the continuous hemorrhagic volume is less in 24 h and neurological deficit score is improved in the acupuncture group. Acupuncture brings the positive significance in the treatment of cerebral hemorrhage at the early stage.</p>

Three-dimensional reconstruction and anatomic variation of the portal vein based on 64-slice spiral CT data / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the three-dimensional reconstruction methods of the portal vein using 64-slice spiral CT data and the anatomical variation of the portal vein.</p><p><b>METHODS</b>Three-dimensional reconstruction of the portal vein was performed using Mimics software based on the 64-slice spiral CT data of 64 cases. Each model of the portal vein and its branches was evaluated according to the presentation rate, depiction quality and anatomic variation.</p><p><b>RESULTS</b>The reconstructed model showed a depiction rates of 100% for the 4-grade branches of the portal vein. The stem of the portal vein and the left and right branches of the level III or above were all displayed, but in 2 cases the superior mesenteric vein and in 1 case the spleen vein was displayed only to the level IV. Of the 64 cases, 50 (78.1%) had normal portal vein and 14 (21.9%) showed anatomical variations.</p><p><b>CONCLUSION</b>The 3D model vividly mimics the anatomic variations of the portal vein to provide valuable information for surgical plans.</p>
