BACKGROUND:Methylene blue can hinder abnormal pain conduction via the sensory nerve, and its mechanism is to block bradykinin-induced hyperalgesia and eliminate pain caused by local tissue inflammation.
OBJECTIVE:To observe the influence of methylene blue solution on the lumbar spinal cord and spinal ganglia function of rats, and to investigate whether methylene blue is safe for treating discogenic low back pain.
METHODTotal y 120 Wistar rats were randomly divided into five groupthree experimental groups, a saline control group and a blank control group, n=24 in each group. Lumbar segmental dura was exposed in rats. In the three experimental groups, 0.2, 1, and 2 mL methylene blue were injected epidural y, respectively. The saline control group was subjected to the epidural injection of 1 mL saline. In the blank control group, there was no treatment. Six rats from each group were selected randomly and perfused at 30 minutes, 2 hours, 24 hours, 72 hours after injection, respectively. Then, the corresponding segments of the spinal cord and ganglions were removed. Hematoxylin eosin staining was used for comparing histological and structural changes under light microscope.
RESULTS AND CONCLUSION:Hematoxylin-eosin staining showed that at 30 minutes, 2 hours, 24 hours and 72 hours after injection of methylene blue, the spinal dorsal side exhibited the structural integrity, clear boundaries between the white matter and gray matter, dense nerve fibers in the white matter, and round or oval nuclei of glial cells among fibers;dense nerve fibers in the posterior horn of gray matter;light-colored neuronal nuclei with prominent nucleoli;a bundle of nerve fibers among cellpopulations. There was no significant change in tissue structure of lumbar spinal cord and spinal ganglia between the experimental groups and the saline control group or between the experimental groups and the blank control group. Thus, the epidural injection of 1%methylene blue has no significant effect on the spinal cord and spinal nerve structures.

Objective:To investigate the effect of Qingre-Tongfu enema combined with noninvasive positive pressure ventilation on the ventilation function of elderly patients with severe pneumonia. Methods:A total of 60 elderly patients with severe pneumonia with syndrome of excess of Yangming fushi from September 2017 to August 2019 in the respiratory department of the First People’s Hospital of Dongcheng District, Beijing were randomly divided into two groups, 30 cases in each group. The control group was treated with western medicine to control infection and noninvasive positive pressure ventilation. The treatment group was treated with Qingre-Tongfu enema on the basis of the control group. The Traditional Chinese Medicine Syndrome score (TCMSSS), Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE-Ⅱ) and Clinical Pulmonary Infection Score (CPIS) were compared before and after treatment, The Pneumonia Severity Index (PSI) was compared. Serum procalcitonin (PCT) was detected by upconversion luminescence immunoassay, CRP was detected by double antibody sandwich ELISA, WBC was detected by automatic hematology analyzer; partial pressure of carbon dioxide (PaCO 2), oxygen saturation (SaO 2), partial pressure of oxygen (PaO 2) were detected by blood gas analyzer, oxygenation index (OI) and respiratory rate (RR) were calculated. The complications were investigated and the clinical efficacy was evaluated. Results:The total effective rate was 96.7% (29/30) in the treatment group and 73.3% (22/30) in the control group, with significant difference between the two groups ( χ2=4.706, P=0.030). After treatment, the levels of serum PCT, CRP and WBC in the treatment group were significantly lower than those in the control group ( t=15.359, 25.784 and 13.460, respectively, P<0.01); after treatment, the levels of SaO 2 [(93.18 ± 3.79)% vs. (88.78 ± 5.56)%, t=3.584], PaO 2 [(86.81 ± 4.01) mmHg vs. (80.01 ± 4.76) mmHg, t=5.975], OI [(285.53 ± 15.05) mmHg vs. (227.65 ± 12.37) mmHg, t=16.272] in the treatment group significantly were higher than those in the control group ( P<0.01); PaCO 2 [(43.28 ± 6.84) mmHg vs. (48.83 ± 7.66) mmHg, t=-2.956], RR [(22.00 ± 3.79) times/min vs. (26.30 ± 3.73) times/min, t=-4.434] in the treatment group were significantly lower than those in the control group ( P<0.05). After treatment, the scores of TCMSSS, APACHE-Ⅱ, CPIS and PSI in the treatment group were significantly lower than those in the control group ( t=41.310, 11.035, 8.399, 5.752, P<0.01). The treatment group in the course of antibiotics, mechanical ventilation time, hospital stay were significantly shorter than the control group ( P<0.01). Conclusion:Qingre-Tongfu enema combined with noninvasive positive pressure ventilation can improve the clinical symptoms of elderly patients with severe pneumonia, reduce inflammatory reaction, shorten the time of mechanical ventilation and antibiotic treatment, and improve the clinical efficacy.

Impaired ability to undergo apoptosis in response to a wide range of external stimuli acquires melanomas a selective advantage for progression and metastasis as well as their notorious resistance to therapy. Changes at genomic, transcriptional and post-translational levels of G-proteins and protein kinases (Ras) , their transcription factor effectors (c-jun,ATF2, stat3 and NF-?B) and upregulator of antiapoptosis gene (Bcl-2、Bcl-X_L、survivin、ML-IAP)affects apoptosis-induced of TNF, Fas and TRAIL receptors, which play important roles in acquiring melanoma's resistance to apoptosis. The complexity of the molecular variants involved in signal transduction along apoptotic pathways suggests that the cell may have a variety of possibilities for regulating apoptosis and generating apoptosis deficiency.

Cutaneous dyschromia is a common problem of plastic and cosmetic surgery. There are not good methods to resolve this problem in present. The mechanisms of skin pigmentation process are not well understood. It is now recognized the correlation between melanogenesis and alpha-melanocyte-stimulating hormone. Alpha-msh enhances activity and quantity of tyrosinase as well as stimulates melanogenesis, specifically to stimulate eumelanin synthesis by activating the melanocortin-1 receptor (MC-1R) on melanocytes. Alpha-msh stimulates melanocyte prolixferation, formation of dendricity, and transfer of melanosomes to keratinocytes, It also protects melanocytes from the damaging effects by immunomodulation. Also, alpha-msh interact with other factors to affect pigmentation indirectly. Agouti signaling protein(ASIP) is a endogeneous antagonist of alpha-msh can induces pheomelanin synthesis by competing with alpha-msh for binding to the MC-1R.Follwing better understood the mechanisms of skin pigmented process, it will provide effective methods to resolve acquired human cutaneous hyperpigmentation and hypopigmentation.
