ABSTRACT
@#【Objective】 To explore the current status and development trend of research on external therapies in traditional Chinese medicine (TCM) for insomnia over the past 10 years through bibliometrics and visual analysis, to provide references for further research on the topic. 【Methods】 Literature relating to TCM external therapies for insomnia from January 1, 2012 to December 31, 2021 was retrieved from Chinese databases, including China National Knowledge Infrastructure (CNKI), Wanfang Database, China Science and Technology Journal Database (VIP), and from the Web of Science Core Collection (WOSCC) for English articles. CiteSpace, VOSviewer, Scimago Graphica, and NoteExpress software were used to analyze publication volumes of the papers and how they were distributed in different journals, as well as to visualize the data of the countries, authors, institutions, and keywords. 【Results】 A total of 6 085 papers were obtained, of which 5 592 were from the Chinese databases and 493 were from the English database, with their publication volumes growing steadily year on year. Approximately 45 countries and regions were found to have published research on the topic. In terms of Chinese publications, the author with the most papers published was CHEN Yunfei from Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine. The closest collaboration was between LIU Chengyong from the Affiliated Hospital of Nanjing University of Chinese Medicine and YUE Zenghui from Hunan University of Chinese Medicine. In terms of English publications, the author with the most papers published was MAO Junj from Sloan-Kettering Cancer Research Center, USA, and LAO Lixing from the University of Hong Kong was his closest partner in collaboration. Heilongjiang University of Chinese Medicine was the institution with the most Chinese publications, and Shanghai University of Traditional Chinese Medicine was the one with the most English papers published. Studies on the topic were published in 386 Chinese journals and 205 English journals, respectively. Nowadays, the clinical application of TCM external treatments for insomnia, the selection of meridians and acupoints, therapies for insomnia and its related diseases are research hotspots. The combined use of different TCM external therapies is a trend in the treatment of insomnia and its concomitant diseases, especially in the fields of oncology, nursing, and psychiatric disorders. The exploration of mechanisms of TCM external therapies for insomnia is also a key direction for future research. In clinical practice, the commonly used external therapies for insomnia include acupuncture, ear-acupressure with beans, acupoint application, etc. The commonly selected acupoints are auricular points, Sishencong (EX-HN1), Shenmen (HT7), etc. The frequently studied meridians are Ren, Du, Qiao, etc. The insomnia concomitant diseases are depression, stroke, anxiety, etc. 【Conclusion】 A wealth of research results have been accumulated in the treatment of insomnia by TCM external therapies, but authoritative research results are not so many. Therefore, institutions in different countries should strengthen communications and cooperation, and researchers should be encouraged to make innovations and breakthroughs on the basis of inherited TCM external therapies, so as to produce more valuable research results and improve TCM external therapies for providing better treatments for patients with sleep disorders.
ABSTRACT
Objective @# To analyze the morphology and incidence of middle mesial canal (MM) and isthmus in the mandibular first permanent molar by cone-beam computed tomography (CBCT).@*Methods@# Statistical analysis was performed on images from patients who underwent CBCT examination in the Department of Radiology at Stomatological Hospital, Southern Medical University. Samples exhibiting root canal treatment, root resorption and calcification were excluded. Data regarding sex, age, the presence or absence of isthmus and MM, and the number of roots and root canals were recorded.@*Results @#Of the 217 mandibular first molar samples, 8 (3.7%) had an MM, and 2 (0.9%) had an independent apical foramen. The overall incidence rate of isthmus was 57.1%; this rate was 50.7% in the cervical third of the root canal, 17.5% in the middle third, and 13.4% in the apical third. The incidence rate of isthmus was 61.8% on the left side, 52.3% on the right side, 58.7% in males, and 55.8% in females. No significant difference was found between the left and right sides or between females and males (P > 0.05). The incidence rate of isthmus in people under 60 was greater than 50% but was significantly lower in people older than 60.@*Conclusion@#Only a very small proportion of MMs have an independent apical foramen in the mandibular first molar. The incidence of isthmus in the mesial root of the mandibular first permanent molar is high, and isthmus usually occurs in the cervical third of the root canal. During root canal treatment or apical surgery, attention should be given to the physical and chemical preparation of the isthmus.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the use of titanium mesh reconstruction after sternal tumor resection.</p><p><b>METHODS</b>From January 2007 to January 2011, 14 patients with sternal tumors were admitted into Peking Union Medical Hospital. The clinical characteristics, surgical resection, and technique of reconstruction were reviewed.</p><p><b>RESULTS</b>Of the 14 patients, 3 had a metastatic sternal tumor, the primary sites of which were as follows: hepatic carcinoma in one case (metastasis 19 years after operation), breast carcinoma in another case (metastasis 5 years after operation), and renal carcinoma in the other case (found simultaneously). Two patients showed local involvement of the sternum: 1 had thymic carcinoma, and the other had myofibrosarcoma. The remaining 9 patients had primary tumors: 4 were osteochondroma, 3 chondrosarcoma, 1 eosinophilic granuloma, 1 non-Hodgekin's lymphoma. En bloc resection of the sternal tumor was performed in all the 14 patients. The defect was repaired with the titanium mesh adjusted to the shape of the defect and fixed with the stainless steel wire. Eleven patients were followed up for a period from 2 months to 4 years, during which no translocation or broken of the titanium mesh was observed.</p><p><b>CONCLUSIONS</b>Radical en bloc excision remains the treatment of choice for sternal tumors. Sternum defect reconstruction using titanium mesh as a rigid replacement proves appropriate and effective.</p>

Objective: To investigate the protective effect of erythropoietin (EPO) on the acute renal injuries caused by abdomen open injury plus seawater immersion in rats. Methods: Sixty healthy male Wistar rats (clean grade) were evenly randomized into four groups,namely,EPO pre-treatment group,observation group,low-dose EPO treatment group and high-dose EPO treatment group. Acute renal injury was induced by abdomen open injury plus artificial seawater immersion (22°C). The serum creatine, BUN, creatine kinase, creatine kinase isoenzyme, TNF-α, IL-6, complement C3a, C-reactive protein, renal homogenate superoxide dismutase (SOD) , and the renal pathological changes were observed and compared between different groups. Results: Acute renal injury was observed in all groups 3 hours after abdomen open injury plus seawater immersion,with increased serum creatine and BUN,but the rats survived after treatment. The serum creatine,BUN,creatine kinase,and creatine kinase isoenzyme in EPO pre-treatment group were significantly lower than those of the other 3 groups; the levels of TNF-α,IL6, complement C3a ,and C-reactive protein were also obviously decreased; the renal homogenate SOD was obviously increased; and the score of renal proximal tubule necrosis was obviously decreased. However,no significant differences were found between the high- and low-dose EPO groups concerning all the parameters (P>0.05). Conclusion: EPO pre-treatment has a protective effect on the acute renal injury induced by abdomen open injury plus seawater immersion in rats.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the changes and influencing factors of early postoperative pulmonary function of thoracotomy.</p><p><b>METHODS</b>Pre- and early postoperative pulmonary function was studied in 64 consecutive cases with optimal thoracotomy. Pain assessment was done before pulmonary function test, and the chief complaints of patients were recorded after the procedure. The changing curves of pulmonary function were done and the differences associated with groups, surgical styles, pain assessment, epidural analgesia, chief complaint and preoperative conditions were analyzed.</p><p><b>RESULTS</b>Pulmonary function was severely lowered to about 40% of the base line on the first day, and it was rehabilitated to about 60% of the base line on the eighth day. There was a greater gradient on the recovery curve on the 3rd and 4th days. Epidural analgesia was able to improve pain relaxation and pulmonary function in some degree. Single-factor analysis showed that postoperative pain, postoperative day and surgical style were the significant influencing factors for early postoperative pulmonary function. By multiple-factor analysis, preoperative pulmonary function, age and postoperative pain were the main factors, while surgical style had only weak effect on it.</p><p><b>CONCLUSIONS</b>Early postoperative pulmonary function is severely impaired by thoracotomy. It rehabilitate gradually with time. Improvement of preoperative pulmonary function, reducing surgical procedure injuries, especially injury to respiratory muscle system, and enough postoperative pain relief are the most important means that would reduce pulmonary function impairment and consequently reduce postoperative pulmonary complications.</p>
