[Manifestations and distribution rules of jingjin lesions in neck-type cervical spondylosis].

OBJECTIVE: To explore the manifestations of jingjin (sinews/fascia) lesions and summarize their distribution rules in the patients with neck-type cervical spondylosis so as to provide the evidences for the development of clinical diagnosis and treatment scheme of acupuncture for cervical spondylosis. METHODS: A total of 120 patients with neck-type cervical spondylosis were collected. The meridian diagnostic method was used to examine the upper back of each patient, the manifestation category of jingjin lesions, locations and the affected muscle regions of twelve meridians were recorded. RESULTS: (1) The punctate lesions of jingjin were detected in 15 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (113 cases, 94.2% of lesion frequency). The lesion frequency of 10 regions was ≥50.0%. The punctate lesions were mainly distributed in the muscle regions of hand-shaoyang (349 cases) and foot-taiyang (333 cases). (2) The linear lesions of jingjin were detected in 10 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (77 cases, 64.2% of lesion frequency). The lesion frequency of 2 regions was ≥50.0%. The linear lesions occurred mainly in the muscle region of foot-taiyang (251 cases). (3) Eight regions were examined to be the planar lesions of jingjin, and the highest frequency of lesion was found in the site of Jianjing (GB 21) (84 cases, 70.0% of lesion frequency). The lesion frequency of 3 regions was ≥50.0%. The muscle region of foot-taiyang (260 cases) was predominated in the planar lesions. (4) The distribution of all of the punctate, linear and planar lesions of jingjin was analyzed statistically. It was found that 25 regions were involved and those with the high lesion frequency were distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13), the sites of Jianjing (GB 21) and Dazhui (GV 14), transverse processes of C3 to C5 and the area from the lateral border of the scapula to the teres minor, separately. The muscle regions of foot-taiyang, hand-shaoyang and hand-yangming were involved in various kinds of jingjin lesions. CONCLUSION: Jingjin lesions in patients with neck-type cervical spondylosis can be divided into three categories, namely, punctate, linear and planar lesions; of which, the punctate lesions are dominated. A majority of jingjin lesions is related to the muscle region of foot-taiyang, and the lesion frequency is higher compared with the lesions to the muscle regions of hand-shaoyang and hand-yangming. Jingjin lesions are commonly distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13).

[Clinical observation on distribution characteristics and rules of pain sensitivity points on body surface in patients with knee osteoarthritis].

OBJECTIVE: To observe the distribution characteristics and rules of pain sensitivity points on body surface in patients with knee osteoarthritis (KOA). METHODS: A total of 916 patients with KOA were selected in this study, the pain sensitivity points of local site of knee joint were probed by thumb palpation. Tape was used to measure the distance between the pain sensitivity points and the most nearby acupoints. The Wagner tenderness measuring instrument was used to measure the tenderness threshold of pain sensitivity points. RESULTS: A total of 3618 pain sensitivity points were probed, among them, 3338 pain sensitivity points were sensitized. The minimum sensitization degree was 1.00, the maximum sensitization degree was 3.39, while the average sensitization degree was (2.16±0.60). Pain sensitivity points were distributed 0.37-1.73 cun around the acupoints, the average distance was (1.26±0.20) cun. Most of the pain sensitivity points (48.7%) were around Yingu (KI 10), Ququan (LR 8) and Xuehai (SP 10). The number and sensitization degree of pain sensitivity points were associated with McGill pain questionnaire score of patients with KOA (P<0.001). CONCLUSION: The pain sensitivity points of patients with KOA may be the expansion effect of acupoint areas in the disease states, pain sensitivity points are more likely to appear on the medial side of knee joint.

LCMS-IT-TOF Analysis of Retention Behavior of Sanguisorbae Radix Components on D101 Macroporous Resin and Polyamide Resin / 中国实验方剂学杂志

Objective:To study on the material basis of Sanguisorbae Radix by column chromatography and liquid chromatography-ion trap-time-of-flight mass spectrometry (LCMS-IT-TOF), and analyze the distribution of different components in Sanguisorbae Radix water extract on D101 macroporous resin and polyamide resin. Method:Sanguisorbae Radix water extract was separated by D101 macroporous resin and polyamide resin, and LCMS-IT-TOF was used for detection, chromatography separation was achieved on an ACQUITY UPLC HSS T3 column (2.1 mm×100 mm, 1.8 μm) with the mobile phase consisted of water (A) and acetonitrile (B) for gradient elution (0-10 min, 5%-20%B; 10-18 min, 20%-35%B; 18-23 min, 35%-50%B; 23-28 min, 50%-90%B; 28-30 min, 90%B; 30-33 min, 90%-5%B; 33-35 min, 5%B), the flow rate was 0.3 mL·min-1, the column temperature was 30 ℃. Data acquisition was carried out in electrospray ionization (ESI) under the positive and negative ion modes, the scanning range was m/z 100-1 200. According to mass spectrometry data such as accurate molecular mass and fragment information, combined with literature, different chemical components in loading effluents and ethanol eluents of Sanguisorbae Radix water extract were identified. A heat map of the distribution of components in each fraction was drawn by extracting mass spectrum peak intensity data of each sample. The elution rules of various components were compared visually. Result:The enrichment and separation of D101 macroporous resin and polyamide resin were obvious. Tannins in Sanguisorbae Radix water extract was mainly concentrated in loading effluent of macroporous resin and its water eluent, triterpenoids were mainly distributed in the 90% ethanol eluent of macroporous resin. In the above effluents and eluents, a total of 63 compounds (including isomers) were identified. Among them, 6 compounds, ellagic acid-4-pyranoarabinoside or its isomer, 6-O-galloylnorbergerin, 3-O-galloylnorbergerin, (6-acetyloxy-5,7-dihydroxy-8-methoxy-4-oxochromen-2-yl) acetate, ethyl 2-methyl-5,6-bis (sulfooxy) benzofuran-3- carboxylate were first discovered in Sanguisorbae Radix. Conclusion:The method can quickly and accurately identify the distribution of components in aqueous extract of Sanguisorbae Radix after column chromatography, providing experimental basis for exploring the pharmacodynamic components and mechanism of Sanguisorbae Radix.
