Qualitative research on thematic interviews and factual records of Kampo medicine based on grounded theory / 国际中医中药杂志

Through literature search and screening, with qualitative research methods and the guidance of the three-level coding framework of grounded theory, literature about interview and factual records with Kampo medicine as theme was analyzed to explore concern areas and key points of Kampo medicine. The included literature mainly showed the modern development prospect of Kampo medicine from the fields of the revival background, laws and regulations, clinical work, education and teaching, scientific research, Kampo medicine industry, periodicals and books, representatives, symbolic events, organization and communication of Kampo medicine. Among them, half or more of the literature involved specific aspects such as clinical diagnosis and treatment methods of Kampo medicine, international communication, drug dosage forms and marketing, scientific research institutions and clinical research, and university education. At the same time, the specific aspects of events, legislation, organizations, periodicals, books and representatives mentioned in the literature provided important indexes for the comparative study of traditional medicine between China and Japan. In the future, the above fields and aspects can be set as starting points and main framework to further obtain and research relevant interviews and documentary literature, so as to promote the communication and development of traditional medicine at home and abroad.

Unilateral laminotomy for bilateral decompression under unilateral biportal endoscopy and uniportal endoscopy to treat lumbar spinal stenosis / 中华骨科杂志

Objective:To compare the clinical efficacy of unilateral biportal endoscopy (UBE) and uniportal endoscopy (UE) for unilateral laminotomy for bilateral decompression (ULBD) in the treatment of lumbar spinal stenosis.Methods:Data of 82 patients with lumbar spinal stenosis treated by ULBD under UBE or UE from January 2020 to June 2021 in Dalian Central Hospital affiliated to Dalian Medical University and the First Hospital affiliated to Wenzhou Medical University were retrospectively analyzed, including 36 males and 46 females, aged 63.3±7.5 years (range, 47-81 years). According to the surgical procedure, they were divided into UBE group (42 cases), including 20 males and 22 females; aged 63.2±7.6 years (range, 47-81 years) and UE group (40 cases), including 16 males and 24 females; aged 63.5±7.5 years (range, 48-80 years). Operation time, hospital stay and surgical complications were compared between the two groups. Visual analogue scale (VAS) of low back and leg pain before surgery, 1 day, 7 d, 1 month and 6 months after surgery, and Oswestry disability index (ODI) before surgery, 1 month and 6 months after surgery were compared. Dural sac area before and after surgery, resection angle of ipsilateral facet joint, decompression rate of disc space and bone lateral recess were calculated.Results:All patients were operated successfully. In the UBE group, the operation time was 63.1±7.0 min, and the hospital stay was 3.9±0.9 d. The UE group was 61.2±6.2 min and 3.7±0.9 d, respectively ( t=1.31, P=0.195; t=1.24, P=0.217). The VAS of back and legs pain in UBE group decreased from 7.19±0.97 before operation to 3.43±0.63 points at postoperative 1 day, 1.71±0.60 at postoperative 7 d, 1.33±0.48 at postoperative 1 month and 1.36±0.48 points at postoperative 6 months ( F=352.29, P<0.001). The VAS score of the UE group decreased from 6.85±0.89 points before operation to 2.45±0.75 points at postoperative 1 day, 1.75±0.59 points at postoperative 7 d, 1.33±0.47 points at postoperative 1 month and 1.28±0.45 points at postoperative 6 months ( F=291.44, P<0.001). The VAS of low back and leg pain was higher in the UBE group than in the UE group at 1 day postoperatively ( t=6.41, P<0.001), and the difference was not statistically significant at 7 d postoperatively ( t=-0.27, P=0.786). The ODI of UBE group decreased from 66.62%±4.98% before operation to 21.81%±2.61% at postoperative 1 month and 11.62%±2.31% at postoperative 6 months ( F=1991.35, P<0.001). The ODI score of UE group decreased from 64.35%±5.16% before operation to 22.85%±3.26% at postoperative 1 month and 11.15%±2.86% at postoperative 6 months ( F=1931.18, P<0.001). The postoperative dural sac area of the UBE and UE groups was 135.1±10.0 mm 2 and 120.9±10.4 mm 2 ( t=6.30, P<0.001). The resection angle of ipsilateral facet joint was 69.3°±4.9° and 94.3°±4.1° in the two groups, respectively, with a statistically significant difference ( t=-25.00, P<0.001). The decompression rate of ipsilateral disk-flavum space was 39.0%±3.0% and 38.7%±3.3% in the two groups ( t=1.52, P=0.314). On the contralateral side was 41.6%±3.3% and 22.8%±3.2% ( t=26.32, P<0.001), respectively. The ipsilateral osseous side fossa decompression rate in the two groups were 70.0%±4.8% and 59.3%±3.9% ( t=15.64, P<0.001), the contralateral were 73.0%±3.4% and 48.4%±4.3% ( t=28.86, P<0.001). There was no significant difference in the decompression rate of ipsilateral disco-flavum space or bony lateral recess between the UBE group and the contralateral group ( t=-1.40, P=0.174; t=-1.72, P=0.096), while the decompression rate of discoflavum space and bony side recess on the ipsilateral side of UE group were higher than those on the contralateral side ( t=28.51, P<0.001; t=13.95, P<0.001). Conclusion:Both UE-ULBD and UBE-ULBD have good short-term clinical efficacy in patients with lumbar spinal stenosis. UB is better than UBE in early postoperative pain relief. However, UBE shows better imaging performance in decompression effect and better retention of facet joints.

Preoperative precise location of responsible segment of cervical radiculopathy: the development of selective nerve root block / 中华骨科杂志

Cervical spondylotic radiculopathy is one of the commonly seen spinal surgery diseases. For well?diagnosed and well?located cervical spondylotic radiculopathy, surgical intervention can effectively alleviate symptoms. With the wide appli?cation of minimally invasive surgical techniques, the requirements for precise preoperative orientation of responsible segments have increased, especially in multisegmental cervical spondylotic radiculopathy cases. However, due to the cutaneous pain distri?bution is often atypical, magnetic resonance imaging and neurological examinations may be not reliable enough for accurate loca?tion preoperatively which may fail to get a satisfactory surgical outcome. Selective nerve root block (SNRB) in preoperative localiza?tion of responsible nerve roots in cervical spondylotic radiculopathy has gradually increased. Yet this technology has been mostly used by anesthesiologists or radiologists, this field in minimally invasive spinal surgery is relatively blank. As we know, there is no previous review summarized the commonly used approaches of SNRB, the risk factors relating to complications, and the local pre?cise blood vessels anatomy. In summary, we believe that combination these series of points with the necessity of preoperative pre?cise location in cervical spondylotic radiculopathy may increase the safety of cervical SNRB. The keywords about "cervical" and"selective nerve root block" have been used in English and Chinese literature databases. The articles were filtrated by title, ab?stract and full text. There were 21 articles taken in the review. We summarized the history and distinction of different approaches including anterior lateral approach, lateral approach, posterior lateral approach, dorsal "direct" approach and dorsal'indirect'ap?proach, and described the indication of each approach. As well as the factors associating with catastrophic complications in cervi?cal SNRB, for instance, the vascular distribution relating to vascular mistaken injection, steroid kind selection because large ste?roid particle may block some thin but vital arteries. In addition to cervical local blood vessels distribution and variation, the needle trajectory also played a key role in the complications of SNRB. Besides, other controversy points, such as whether use contrast me?dia or not, the importance of the lateral position of the cervical spine, etc., were discussed in this review based on clinical research?es. The purpose of the present study is hoping to provide some references for spine surgeons to apply SNRB technology more safely.
