[Essence of acupoints and meridians based on the studies of myofascial trigger points].

Based on the modern anatomy and physiology, the referred pain of myofascial trigger points of each muscle is integrated; compared with the twelve meridians as well as conception vessel and governor vessel, the similarity of their position and running course is observed. With the current research progress of myofascial trigger points and fasciology, based on the running course of referred pain of trigger points, combined with fascia mechanics, nerve and vascular, the location of acupoints and meridians, as well as the relationship between acupoints and meridians, are discussed.

NAMPT protects against 6-hydroxydopamine-induced neurotoxicity in PC12 cells through modulating SIRT1 activity.

Parkinson's disease (PD) is the second most common progressive neurodegenerative movement disorder. Nicotinamide phosphoribosyltransferase (NAMPT) catalyzes the first rate­limiting step in the nicotinamide adenine dinucleotide (NAD+) biosynthetic pathway in mammals, is a substrate for NAD+­dependent enzymes, such as sirtuin 1 (SIRT1), and contributes to cell fate decisions. However, the role of NAMPT in PD has remained to be fully elucidated. In the present study, PC12 cells were treated with the neurotoxin 6-hydroxydopamine (6­OHDA) to establish an in vitro model of PD, following which an obvious inhibitory effect on the levels of NAMPT and NAD+ as well as the NAD+/NADH ratio was detected. In addition, pre­incubation with FK866, a highly specific NAMPT inhibitor, enhanced the inhibitory effects of 6­OHDA on the viability of PC12, while pre­incubation with nicotinamide mononucleotide (NMN), am enzymatic product of NAMPT, had the opposite effect. Furthermore, it was revealed that NMN markedly attenuated 6­OHDA­induced decreases in superoxide dismutase activity and glutathione levels, as well as 6­OHDA­induced increases in malondialdehyde and lactate dehydrogenase in PC12 cells. Furthermore, 6­OHDA significantly reduced SIRT1 activity in PC12 cells, which was inhibited by NMN. The pharmacological activator resveratrol also significantly inhibited 6­OHDA­mediated decreases in PC12 cell viability while reversing 6­OHDA­induced decreases in SIRT1 levels. The results of the present study suggested that NMT protected against 6­OHDA­induced decreases in PC12 cell viability, and that SIRT1 activation had a role in this process. Treatment with NMN to activate SIRT1 may represent a novel therapeutic strategy for treating PD.

[Therapeutic effect and safety of microendoscopic discectomy versus conventional open discectomy for the treatment of lumbar disc herniation: a Meta analysis].

OBJECTIVE: To conduct a meta analysis of studies comparing theapeutic effect and safety of microendoscopic discectomy to conventional open discectomy in the treatment of lumbar disc herniation in China. METHODS: A systematic literature retrieval was conducted in the Chinese Bio medicine Database, CNKI database, Chongqin VIP database and Wangfang database. The statistical analysis was performed using a RevMan 4.2 software. The comparison included excellent rate, operation times, blood loss, periods of bed rest and resuming daily activities, hospital stay or hospital stay after surgery, and complications of microendoscopic discectomy versus conventional open discectomy. RESULTS: The search yielded 20 reports, which included 2 957 cases treated by microendoscopic discectomy and 2 130 cases treated by conventional open discectomy. There were 12, 11, 7, 5, 4 and 4 reports which had comparison of operation times, blood loss, period of bed rest, periods of resuming daily activities, hospital stay and hospital stay after surgery respectively. Complications were mentioned in 10 reports. Compared to patients treated by open discectomy, patients treated by microendoscopic discectomy had a higher excellent rates [OR=1.29, 95%CI (1.03, 1.62)], less blood loss[OR=-63.67, 95%CI (-86.78, -40.55)], less period of bed rest[OR=-15.33, 95%CI (-17.76, -12.90)], less period of resumption of daily activities [OR=-24.41, 95%CI (-36.86, -11.96)], less hospital stay [OR=-5.00, 95%CI (-6.94, -3.06)] or hospital stay after surgery [OR=-7.47, 95%CI (-9.17, -5.77) respectively. However, incidence of complications and operation times were proved no significant different between microendoscopic discectomy and open discectomy. CONCLUSIONS: Microendoscopic discectomy and conventional open discectomy in treatment of lumbar disc herniation are both safe, effective; incidence of complications are nearly. Patients with lumbar disc herniation treated by microendoscopic discectomy have fewer blood loss, shorter periods of bed rest and hospital stay, and resume daily activities faster. Techniques are selected according to indications, microendoscopic discectomy should be carried out when conjunct indications occur.

Embryonic natural orifice transluminal endoscopic surgery in the treatment of severe acute pancreatitis complicated by abdominal compartment syndrome.

BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87% in the ENOTES group, which was statistically different from 78.12% in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.
