[Exploring the location of acupoint Dubi (ST35)].

Acupoint Dubi(ST35), one of the commonly used acupuncture points in clinical practice, has long been equated as the acupoint Waixiyan(EX-LE5) in the academic community. By referring to the location of ST35 elaborated in the relevant literature in the ancient and modern times, we analyze the evolution of its position and expound its clinical significance of the correct positioning in the present paper. We think that under posture of knee flexion, the position of ST35 should be between the lower edge of the patella and the upper tip of the tibia, at the midpoint of the patella ligament.

ß­Ecdysterone promotes autophagy and inhibits apoptosis in osteoporotic rats.

Osteoporosis is an aging process of skeletal tissues with characteristics of reductions in bone mass and microarchitectural deterioration of bone tissue. The present study aimed to investigate the effects of glucocorticoid­induced osteoporosis on osteoblasts and to examine the roles of ß­ecdysterone (ß­Ecd) involved. In the present study, an in vivo model of osteoporosis was established through the subcutaneous implantation of prednisolone (PRED) into Sprague­Dawley rats, with or without a subcutaneous injection of ß­Ecd (5 or 10 mg/kg body weight). Expression of Beclin­1 and microtubule­associated protein 1A/1B­light chain 3I/II and apoptosis in lumbar vertebrae tissues was measured by immunofluorescence and TUNEL assays, respectively. Serum concentration of calcium and phosphorus, and the activity of tartrate­resistant acid phosphatase (TRAP) and alkaline phosphatase (ALP) were measured by biochemical assay. Reverse transcription­quantitative polymerase chain reaction and western blotting was used for detect the expression of related genes and proteins. PRED treatment inhibited bone formation by decreasing bone mineral density, and suppressing the expression of Runt­related transcription factor 2 and bone morphogenetic protein 2, while enhancing the activity of alkaline phosphatase, upregulating the expression of receptor activator of nuclear factor-κB ligand, and increasing the serum content of calcium, phosphorus and tartrate­resistant acid phosphatase in rats. Additionally, PRED was revealed to inhibit autophagy through the downregulation of Beclin­1, autophagy protein 5 and microtubule­associated protein 1A/1B­light chain 3I/II expression, whereas it induced the apoptosis, through the activation of caspase­3 and the suppression of apoptosis regulator BCL2 expression. Notably, the PRED­induced alterations in bone formation, autophagy and apoptosis were revealed to be attenuated by ß­Ecd administration. In conclusion, the findings of the present study suggested that ß­Ecd may be a promising candidate for the development of therapeutic strategies for the treatment of osteoporosis, through the induction of autophagy and the inhibition of apoptosis in vivo.

[Studies on pharmacological activity of borneol].

Borneol is a major component of many medicinal plant essential oils, as well as a popular traditional Chinese medicine. This essay collects the results of the latest domestic and foreign studies, and summarizes and analyzes its activity and reaction mechanism on analgesia, putridity elimination and flesh regeneration, and repair of damaged cells. Moreover, it proposes problems concerning borneol during medical studies, providing support for the in-depth study and exploration of efficacies of precious traditional Chinese medicines as well as the effective utilization and development of innovative medicines.

[Clinical observation on three-combination needling method for treatment of primary trigeminal neuralgia].

OBJECTIVE: To probe into a better therapy for primary trigeminal neuralgia. METHODS: Eighty-six cases were randomly divided into an observation group (n = 46) and a control group (n = 40). The observation group were treated with the three-combination needling method, i. e. acupuncture, acupoint-injection and fire-needle therapy, and the control group with acupuncture and acupoint-injection. After treatment of 2 courses, their therapeutic effects were assessed. RESULTS: The total effective rate of 93.5% and the cured rate of 60.9% in the observation group were better than 65.0% and 22.5% in the control group, with significant differences (both P < 0.01). CONCLUSION: The three-combination needling method has obvious clinical therapeutic effect on primary trigeminal neuralgia.

[Clinical study on round-sharp needle therapy combined with massage for prolapse of lumbar intervertebral disk].

OBJECTIVE: To search for a better therapy for prolapse of lumbar intervertebral disk. METHODS: One hundred and sixteen cases were randomly divided into a treatment group treated with round sharp needle plus massage, and a control group with filiform needle plus massage, 58 cases in each group. Changes of symptoms and signs were observed before and after treatment. RESULTS: The effective rate was 98.2% in the treatment group and 82.8% in the control group (P < 0.01). CONCLUSION: Round sharp needle combined with massage has a better therapeutic effect on prolapse of lumbar intervertebral disk.
