Progressive Muscle Relaxation Combined with Chinese Medicine Five-Element Music on Depression for Cancer Patients: A Randomized Controlled Trial

Objectives： To evaluate the effects of progressive muscle relaxation training （PMRT） combined with five elements music therapy of Chinese medicine （CM） for improving anxiety and depression of cancer patients. Methods： From June 2015 to March 2016, 60 cancer patients were included into the study. The patients were randomly assigned to a control group and a treatment group by envelope randomization, receiving PMRT and PMRT plus CM five elements music therapy, respectively, for 8 weeks. Hospital Anxiety and Depression Scale （HADS）, Benefit Finding Scales （BFS）, Functional Assessment of Chronic Illness Therapy-Spiritual （FACIT-Sp）, and Intervention Expectations Questionnaire （IEQU） were adopted to assess the depression of the two groups before and after the treatment. Results： Four cases dropped out during the study, and 29 cases in the treatment group and 27 in the control group were included in the final analysis. Prior to the treatments, the baselines of the 4 questionnaires in the two groups showed no difference. After the 8-week treatment, the treatment group presented better levels of HADS, BFS and FACIT-Sp scores compared with the control group （P〈0.05）. Among the single items of HADS, 4 items involving vexation, feeling fidgeted, pleasure and prospecting the future in the treatment group were improved compared with the control group （P〈0.05）. Conclusions： As a simple and reliable and effective intervention, PMRT combined with five elements music therapy mitigated anxiety and depression of cancer patients. Cancer patients have been found to respond well to psychological intervention in areas regarding stabilisation of emotions, disease awareness, and therapeutic compliance. This brings about a great difference in improving their quality of life and psychological state, offers an effective approach to better self-management in cancer treatment.

A new linearly-combined bi-exponential model for kinetic analysis of the isometric relaxation process of Bufo gastrocnemius under electric stimulation in vitro

There was a slow-relaxing tail of skeletal muscles in vitro upon the inhibition of Ca2+-pump by cyclopiazonic acid (CPA). Herein, a new linearly-combined bi-exponential model to resolve this slow-relaxing tail from the fast-relaxing phase was investigated for kinetic analysis of the isometric relaxation process of Bufo gastrocnemius in vitro, in comparison to the single exponential model and the classical bi-exponential model. During repetitive stimulations at a 2-s interval by square pulses of a 2-ms duration at 12 V direct currency (DC), the isometric tension of Bufo gastrocnemius was recorded at 100 Hz. The relaxation curve with tensions falling from 90% of the peak to the 15th datum before next stimulation was analyzed by three exponential models using a program in MATLAB 6.5. Both the goodness of fit and the distribution of the residuals for the best fitting sup- ported the comparable validity of this new bi-exponential model for kinetic analysis of the relaxation process of the control muscles. After CPA treatment, however, this new bi-exponential model showed an obvious statistical superiority for kinetic analysis of the muscle relaxation process, and it gave the estimated rest tension consistent to that by experimentation, whereas both the classical bi-exponential model and the single exponential model gave biased rest tensions. Moreover, after the treatment of muscles by CPA, both the single exponential model and the classical bi-exponential model yielded lowered relaxation rates, nevertheless, this new bi-exponential model had relaxation rates of negligible changes except much higher rest tensions. These results suggest that this novel linearly-combined bi-exponential model is desirable for kinetic analysis of the relaxation process of muscles with altered Ca2+-pumping activity.

Effects of Isoflurane on the Actions of Neuromuscular Blockers on the Muscle Nicotine Acetylcholine Receptors

Summary: In this study, we tested the hypothesis that volatile anesthetic enhancement of muscle relaxation is the result of combined drug effects on the nicotinic acetylcholine receptors. The poly A m RNA from muscle by isolation were microinjected into Xenopus oocytes for receptor expression. Concentration-effect curves for the inhibition of Ach-induced currents were established for vecuronium, rocuranium, and isoflurane. Subsequently, inhibitory effects of NDMRs were studied in the presence of the isoflurane at a concentration equivalent to half the concentration producing a 50 % inhibition alone. All tested drugs produced rapid and readily reversible concentration-dependent inhibition. The 50 % inhibitory concentration values were 889 μmol/L (95 % CI: 711-1214 μmol), 33.4 μmol (95 % CI: 27.1-41.7 nmol) and 9.2 nmol (95 % CI: 7.9-12.3 nmol) for isoflurane, rocuranium and vecuronium, respectively. Coapplication of isoflurane significantly enhanced the inhibitory effects of rocuranium and vecuronium, and it was especially so at low concentration of NMDRs. Isoflurane increases the potency of NDMRs, possibly by enhancing antagonist affinity at the receptor site.

Difficult airway due to cervical haemorrhage caused by spontaneous rupture of a parathyroid adenoma: A case report

BACKGROUND Cervical haemorrhage due to spontaneous rupture of a parathyroid adenoma is a rare complication that may cause life-threatening acute airway compromise.CASE SUMMARY A 64-year-old woman was admitted to the hospital 1 day after the onset of right neck enlargement, local tenderness, head-turning difficulty, pharyngeal pain, and mild dyspnoea. Repeat routine blood testing showed a rapid decrease in the haemoglobin concentration, indicating active bleeding. Enhanced computed tomography images showed neck haemorrhage and a ruptured right parathyroid adenoma. The plan was to perform emergency neck exploration, haemorrhage removal, and right inferior parathyroidectomy under general anaesthesia. The patient was administered 50 mg of intravenous propofol, and the glottis was successfully visualised on video laryngoscopy. However, after the administration of a muscle relaxant, the glottis was no longer visible and the patient had a difficult airway that prevented mask ventilation and endotracheal intubation. Fortunately, an experienced anaesthesiologist successfully intubated the patient under video laryngoscopy after an emergency laryngeal mask placement. Postoperative pathology showed a parathyroid adenoma with marked bleeding and cystic changes. The patient recovered well without complications.CONCLUSION Airway management is very important in patients with cervical haemorrhage. After the administration of muscle relaxants, the loss of oropharyngeal support can cause acute airway obstruction.Therefore, muscle relaxants should be administered with caution. Anaesthesiologists should pay careful attention to airway management and have alternative airway devices and tracheotomy equipment available.

Synthesis of silver and gold nanoparticles from leaf of Litchi chinensis and its biological activities

Objective: To synthesize and isolate silver and gold nanoparticles from Litchi chinensis leaf methanolic extract, and to evaluate its comparative biological activities including muscles relaxant, analgesic, anti-inflammatory and antidiarrheal. Methods: The gold and silver nanoparticles were synthesized by dissolving methanolic extract in gold chloride and silver nitrate solution separately which were confirmed by colour change and UV-Vis spectroscopy, and pellets were collected through centrifugation. Biological activities of the extract were conducted on BALB/c mice through various standard methods and the data were subjected to One-way ANOVA. Results: The colorless gold chloride solution changed to purple soon after the addition of plant extract, demonstrating that the reaction took place and gold ions were reduced to gold nanoparticles, while colorless silver nitrate solution changed to light and dark brown that was indicative of silver nanoparticles. The muscles relaxant activity showed that silver nanoparticles were more effective than gold nanoparticles and methanolic extract in traction test. The analgesic activity showed that silver and gold nanoparticles showed highest percentage decrease in acetic acid induced writhing at the doses of 50, 100 and 150 mg/kg b.w. The highest anti-inflammatory activity was produced by gold nanoparticles followed by silver nanoparticles, while low activity was observed in methanolic leaf extract. Only the crude methanolic extract showed significant antidiarrheal activity as compared to the standard drug atropine sulphate, while antidiarrheal activities of gold and silver nanoparticles were non-significant. Conclusions: The present work concludes that isolated silver and gold nanoparticles from leaf methanolic extract shows strong muscles relaxant, analgesic and anti-inflammatory activities while crude methanolic extract possesses good antidiarrheal activity.

Sepsis Strengthens Antagonistic Actions of Neostigmine on Flocuronium in a Rat Model of Cecal Ligation and Puncture

Background： The antagonistic actions of anticholinesterase drugs on non-depolarizing muscle relaxants are theoretically related to the activity of acetylcholinesterase （ACHE） in the neuromuscular junction （NMJ）. However, till date the changes of AChE activity in the NMJ during sepsis have not been directly investigated. We aimed to investigate the effects of sepsis on the antagonistic actions ofneostigmine on rocuronium （Roc） and the underlying changes of AChE activity in the NMJ in a rat model of cecal ligation and puncture （CLP）. Methods： A total of 28 male adult Sprague-Dawley rats were randomized to undergo a sham surgery （the sham group, n = 12） or CLP （the septic group, n = 16）. After 24 h, the time-response curves of the antagonistic actions of 0.1 or 0.5μmol/L of neostigmine on Roc （10 μmol/L）-depressed diaphragm twitch tension were measured. Meanwhile, the activity of AChE in the NMJ was detected using a modified Karnovsky and Roots method. The mRNA levels of the primary transcript and the type T transcript of AChE （AChET） in the diaphragm were determined by real-time reverse transcription-polymerase chain reaction. Results： Four of 16 rats in the septic group died within 24 h. The time-response curves of both two concentrations ofneostigmine in the septic group showed significant upward shifts from those in the sham group （P 〈 0.001 for 0.1 μmol/L; P = 0.009 for 0.5 μmol/L）. Meanwhile, the average optical density of AChE in the NMJ in the septic group was significantly lower than that in the sham group （0.517± 0.045 vs. 1.047 ±0.087, P 〈 0.001）. The AChE and AChET mRNA expression levels in the septic group were significantly lower than those in the sham group （P 0.002 for ACHE; P = 0.001 for AChEv）. Conclusions： Sepsis strengthened the antagonistic actions ofneostigmine on Roc-depressed twitch tension of the diaphragm by inhibiting the activity of AChE in the NMJ. The reduced content of AChE might be one of the possible causes of the decreased AChE activity in the NMJ.

Trichosanthes dioica根的神经药理特点(英文)

AIM: Trichosanthes dioica Roxb. (Cucurbitaceae), commonly known as pointed gourd in English, is a dioecious climber grown widely in the Indian subcontinent. Traditionally, this plant has been used in India for several medicinal purposes. The present study aimed to evaluate certain neuropharmacological properties of the hydroalcoholic extract of T. dioica root (TDA) in experimental animal models. METHODS: TDA (at 100 and 200 mg·kg-1 body weight, p.o.) was evaluated for anti-nociceptive activity by the acetic acid-induced writhing and tail flick methods. Locomotor depressant activity was measured by means of an actophotometer. Skeletal muscle relaxant effects were evaluated by using a rota-rod apparatus, and the sedative potentiating property by a phenobar-bitone-induced sleep potentiation study. RESULTS: The results of the present study revealed significant (P<0.001) and dose dependent anti-nociceptive, locomotor depressant, muscle relaxant, and sedative potentiating effects of TDA, demonstrating its depressant action on the central nervous system (CNS). CONCLUSION: From the present study, it can be concluded that T. dioica root possessed prominent anti-nociceptive, as well as depressant, action on the CNS, as manifested by these important neuropharmacological properties in mice.

CB1 receptor localization in rat spinal cord and roots,dorsal root ganglion,and peripheral nerve

AIM:The localization of CB1 receptors in the spinal cord,spinal roots,dorsal root ganglion(DRG),and peripheral nerve of the rat was determined.METHODS:We studied the distribution of CB1 cannabinoid receptors by immunohistochemistry using an antibody raised against the N-terminal of the receptor.RESULTS:The spinal cord showed numerous transverse fibers labelled for CB1 receptors throughout and concentrated in the dorsal horn.Lightly-stained cells were observed throughout the spinal cord gray matter.The DRG also showed cells and fibers labelled for CB1 receptors.Labelled fibers were observed in both dorsal and ventral roots as well as in peripheral nerves.CONCLUSION:The presence of CB1 receptors in the DRG,the dorsal root,and the dorsal horn is in accordance with the analgesic effects of cannabinoids.The presence of labelled cells and fibers in the ventral horn and ventral root provides a substrate for cannabinoid-induced muscle relaxant and antispastic effects.
