[Characteristics of acupuncture and moxibustion therapy in Tibetan medicine based on Medical Canon in Four Sections].

By tracing to the origin of Tibetan medicine, it is known that Tibetan medicine absorbs a variety of medical ideas such as traditional Chinese medicine, Vedic medicine, Persian medicine and Byzantine medicine, and forms a unique theoretical system. The meridian-acupoint system and the characteristics and application of external therapies such as bloodletting and moxibustion in Tibetan medicine are analyzed by elaborating the relevant aspects of acupuncture and moxibustion involved in treatment of diseases listed in Medical Canon in Four Sections. The paper emphasizes the introduction of ironing moxibustion and huo'er moxibustion of fire moxibustion and the application of separation-action decoction and ghee therapy in bloodletting, as well as alternative therapy. Besides, by taking the external treatment of cirrhotic ascites and head trauma as an example, the idea of acupuncture and moxibustion therapy in Tibetan medicine embodied in the Medical Canon in Four Sections is explained so as to benefit the development of acupuncture and moxibustion therapy in Tibetan medicine.

The Commensal Anaerobe Veillonella dispar Reprograms Its Lactate Metabolism and Short-Chain Fatty Acid Production during the Stationary Phase.

Veillonella spp. are obligate, anaerobic, Gram-negative bacteria found in the human oral cavity and gut. Recent studies have indicated that gut Veillonella promote human homeostasis by producing beneficial metabolites, specifically short-chain fatty acids (SCFAs), by lactate fermentation. The gut lumen is a dynamic environment with fluctuating nutrient levels, so the microbes present shifting growth rates and significant variations of gene expression. The current knowledge of lactate metabolism by Veillonella has focused on log phase growth. However, the gut microbes are mainly in the stationary phase. In this study, we investigated the transcriptomes and major metabolites of Veillonella dispar ATCC 17748T during growth from log to stationary phases with lactate as the main carbon source. Our results revealed that V. dispar reprogrammed its lactate metabolism during the stationary phase. Lactate catabolic activity and propionate production were significantly decreased during the early stationary phase but were partially restored during the stationary phase. The propionate/acetate production ratio was lowered from 1.5 during the log phase to 0.9 during the stationary phase. Pyruvate secretion was also greatly decreased during the stationary phase. Furthermore, we have demonstrated that the gene expression of V. dispar is reprogrammed during growth, as evidenced by the distinct transcriptomes present during the log, early stationary, and stationary phases. In particular, propionate metabolism (the propanediol pathway) was downregulated during the early stationary phase, which explains the decrease in propionate production during the stationary phase. The fluctuations in lactate fermentation during the stationary phase and the associated gene regulation expand our understanding of the metabolism of commensal anaerobes in changing environments. IMPORTANCE Short-chain fatty acids produced by gut commensal bacteria play an important role in human physiology. Gut Veillonella and the metabolites acetate and propionate, produced by lactate fermentation, are associated with human health. Most gut bacteria in humans are in the stationary phase. Lactate metabolism by Veillonella spp. during the stationary phase is poorly understood and was therefore the focus of the study. To this end, we used a commensal anaerobic bacterium and explored its short-chain fatty acid production and gene regulation in order to provide a better understanding of lactate metabolism dynamics during nutrient limitation.

Electrochemically Enabled Intramolecular Amino- and Oxysulfonylation of Alkenes with Sodium Sulfinates to Access Sulfonylated Saturated Heterocycles.

A practical and efficient electrochemical intramolecular amino- or oxysulfonylation of internal alkenes equipped with pendant nitrogen or oxygen-centered nucleophiles with sodium sulfinate was developed. Under undivided electrolytic cell conditions, a variety of sulfonylated N-heterocycles and O-heterocycles, such as tetrahydrofurans, tetrahydropyrans, oxepanes, tetrahydropyrroles, piperidines, δ-valerolactones, etc., were efficiently prepared from easily accessible unsaturated alcohols, carboxylic acids, and N-tosyl amines without the need for additional metal or exogenous oxidant. The robust electrochemical transformation features excellent redox economy, high diastereoselectivity, and broad substrate specificity, which provide a general and practical access to sulfone-containing heterocycles and would facilitate the related synthetic and biological studies based on this electrosynthesis.

[Percutaneous foraminal endoscopy for the treatment of lumbar lateral recess stenosis in elderly].

OBJECTIVE: To investigate the clinical efficacy and safety of percutaneous foraminal endoscopy in the treatment of lumbar lateral recess stenosis in elderly. METHODS: The clinical data of 31 elderly patients with lumbar lateral recess stenosis treated by percutaneous foraminal endoscopic decompression from March 2018 to August 2019 were retrospectively analyzed. Including 16 males and 15 females, aged from 65 to 81 years with an average of (71.13±5.20) years, the course of disease ranged from 3 months to 7 years with an average of (14.36±6.52) months. Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to assess clinical symptom and functional status before operation and 1, 6, 12 months after operation. At the final follow-up, the modified Macnab standard was used to evaluate clinical efficacy. RESULTS: All patients were completed the operation successfully. The operation time was from 75 to 120 min with an average of (97.84±11.22 ) min. All 31 patients were followed up from 12 to 28 months with an average of (17.29±5.56) months. Postoperative lumbago-leg pain VAS and ODI were significantly improved at 1, 6, and 12 months(P<0.01). At the final follow-up, according to the modified Macnab standard to evaluate the effect, 23 got excellent results, 5 good, 3 fair. One patient had severe adhesions between peripheral tissues and nerve root, and postoperative sensory abnormalities in the lower extremities were treated conservatively with traditional Chinese medicine and neurotrophic drugs, which recovered at 2 weeks after surgery. No complications such as nerve root injury and infection occurred. CONCLUSION: The intervertebral foraminal endoscopy technique, which is performed under local anesthesia for a short period of operation, ensures adequate decompression while minimizing complications, and is a safe and effective surgical procedure for elderly patients with lumbar lateral recess stenosis.

[JIAO Mian-zhai's academic characteristics on acupuncture].

Professor JIAO integrated martial arts and qigong with acupuncture needling technique, and then created his own "yunzhang bafa" (eight kinds of palm movement and qi training method) and modified the basic skills for finger strength practice and needling techniques. On the base of the needling techniques exerted by both hands, he developed a set of "JIAO 's needling techniques", including the manipulations of needle insertion and withdrawal. He proposed that the compound needling techniques for reinforcing and reducing should be cooperated with the physician's respiratory rhythm. Besides, he clarified the operation timing of reinforcing and reducing techniques to ensure the full play to the curative effect of acupuncture.

[Current status and progress of percutaneous spinal endoscopy in the treatment of degenerative lumbar spinal stenosis].

Percutaneous endoscopic spine decompression(PSED) in recent years in the treatment of degenerative lumbar spinal stenosis(DLSS) achieved excellent results.Compared with traditional open surgery, which is characterized by large trauma, much bleeding, longer bed stay and slow recovery, the rapid development of PSED technology has greatly reduced the surgical trauma, postoperative recovery time and complications of DLSS patients. PSED core as the target therapy, with minimal trauma at the same time to achieve satisfactory decompression effect for lumbar spinal stenosis. Depending on the level, location, and degree of lumbar spinal stenosis, it is important to determine the ideal treatment. However, in practice, PSED has insufficient understanding of the treatment of different pathological types of lumbar spinal stenosis, such as indication selection, surgical approach selection, advantages and limitations of various approaches, and endoscopic vertebral fusion.At present, with the deepening of PSED research and the improvement of endoscopic instruments, great progress has been made in the treatment of DLSS.In this paper, the research progress in the treatment of DLSS by PSED in recent years will be described from four aspects, namely, the grasp of indications, the selection of approaches, the advantages and disadvantages of endoscopic approaches, and endoscope-assisted vertebral fusion, in order to provide certain guidance for the clinical treatment of DLSS by PSED.

[Exploration of professor ZHANG Shan-chen's academic thoughts].

Professor ZHANG Shan-chen's clinical experience and academic thoughts in the field of acupuncture are summarized. Professor ZHANG stresses on theoretical exploration and has written Zhenjiu Jiayijing Shuxue Chongji, published a series of articles on textual research and expounded the nomenclature of acupoints. He believes that clinical practice should be guided by theory and the comprehensive syndrome differentiation be emphasized. Hence, a holistic idea should be cultivated, in which, the human body is considered as an organic whole and should be adaptive to the nature. Based on the theory above, the diagnosis can be determined and the effective treatment be received. He suggests selecting few acupoints, identifying the deficiency from the excess so as to determine the reinforcing or replenishing method and exerting appropriate needling manipulation. Additionally, the response should be enhanced on the identification of deqi after needle insertion. Moreover, a great consideration is laid on the clinical trial and application of moxibustion, which is complemented with acupuncture technique each other and mutually conductive to the clinical effect.

Complementary Copper-Catalyzed and Electrochemical Aminosulfonylation of O-Homoallyl Benzimidates and N-Alkenyl Amidines with Sodium Sulfinates.

A complementary copper-catalyzed and electrochemical aminosulfonylation of O-homoallyl benzimidates and N-alkenyl amidines with sodium sulfinates was developed. The terminal alkene substrate produced sulfone-containing 1,3-oxazines and tetrahydropyrimidines in the presence of Cu(OAc)2, Ag2CO3, and DPP, and under similar reaction conditions, sulfonylated tetrahydro-1,3-oxazepines were prepared from 1-aryl-substituted O-homoallyl benzimidates in moderate to good yields. For certain electron-rich 1,1-diaryl-substituted alkene substrates, the corresponding tetrahydro-1,3-oxazepines could also be obtained in similar or even higher yields via a green electrochemical technique.

OBJECTIVE: To analyze the clinical efficacy, indications and operative points of transforaminal approach and interlaminar approach in the treatment of L4,5 lumbar disc herniation. METHODS: A retrospective analysis was performed on 48 patients with L4,5 lumbar disc herniation treated by percutaneous endoscopic lumbar discectomy from November 2016 to June 2018. Among them, 32 patients underwent percutaneous endoscopic transforaminal discectomy(PETD), including 17 males and 15 females, with an average age of (60.22±16.55) years, and the course of disease was(2.18±2.68) months;16 patients underwent percutaneous endoscopic interlaminar discectomy(PEID), including 7 males and 9 females, with an average age of (42.25±15.89) years, and the course of disease was(2.90±3.02) months. VAS, ODI of two groups before operation, 3 days, 3 months, and 6 months after operation were analyzed, and modified Macnab standard was used to evaluate the clinical effects. RESULTS: All the 48 patients successfully completed the surgical treatment, and all patients were followed up. There was no significant difference in gender, course of disease and follow-up time between two groups (P>0.05). The age of PETD group was(60.22±16.55) years and PEID group was (42.25±15.89) years, there was statistical difference between two groups (P<0.05 ). In the PETD group, there were 10 patients with advanced age, non-free type(24 cases) was more than free type(8 cases), and shoulder type(27 cases) more than axillary type(1 case) and ventral type(4 cases). PETD was used in 5 patients with lateral type and 2 patients with extreme lateral type. In PEID group, the axillary type(8 cases) was more than the shoulder type(2 cases) and the ventral type(6 cases), PEID was used in 4 patients with high prolapse free type(I and IIregions). VAS scores and ODI of patients in two groups at each postoperative follow-up point were significantly improved compared with those before surgery(P<0.05). According to modified Macnab standard to evaluate the clinical effect, in PETD group, 24 cases obtained excellent results, 5 good, 2 fair, 1 poor, while in PEID group, 12 excellent, 3 good, 0 fair, 1 poor. CONCLUSIONS: Both two surgical approachs can achieve satisfactory efficacy in treating L4,5 lumbar disc herniation, but PETD is more suitable for elderly patients, non-free type, lateral type, extremely lateral type and shoulder type of lumbar disc herniation. High prolapse(I and II regions) and axillary type lumbar prominent should select PEID.
