Oxidative Damage to BV2 Cells by Trichloroacetic Acid: Protective Role of Boron via the p53 Pathway / 生物医学与环境科学（英文）

This study aimed to investigate the neurotoxicity induced by trichloroacetic acid (TCA) and the possible protective mechanisms of boron (B). Mouse BV2 cells were treated with TCA (0, 0.39, 0.78, 1.56, 3.12, 6.25, or 12.5 mmol/L) and B (0, 7.8, 15.6, 31.25, 62.5, 125, 500, or 1,000 mmol/L) for 3 h and 24 h, respectively. Then, reactive oxygen species, and supernatant proinflammatory cytokine and protein levels were analyzed after 24 h of combined exposure. Beyond the dose-dependent decrease in the cellular viability, it clearly increased after B supplementation ( P < 0.05). Moreover, B decreased oxidative damage, and significantly down-regulated IL-6 levels and up-regulated TNF-β production ( P < 0.05). B also decreased apoptosis via the p53 pathway. The present findings indicated that TCA may induce oxidative damage, whereas B mitigates these adverse effects by decreasing cell apoptosis.

Platycodon grandiflorum extract attenuates lipopolysaccharide-induced acute lung injury via TLR4/NF-κBp65 pathway in rats.

The traditional Chinese medicine Platycodon grandiflorum (PG) is often used for the treatment of a number of chronic inflammatory diseases. In Chinese veterinary clinic, PG is always extracted by decoction and taken orally, however, the molecular mechanism of PG extract (PE) to reduce LPS-induced inflammation, especially acute lung injury (ALI) in vivo, are not known. Thus, we have studied the anti-inflammatory effects of PE on lipopolysaccharide (LPS)-induced acute lung injury via TLR4/NF-κBp65 pathway in rat. Sprague-Dawley rats were randomly divided into 4 groups: control group, LPS group, LPS±PE low dose group and LPS±PE high dose group. All rats were given corresponding PE solution or the same amount of normal saline by intragastric administration for 7 days. On the 7th day, 1 h after the last administration, 500 µg of LPS were introduced intratracheally to establish ALI rat model, and the same volume of normal saline was given to control group. The results showed that PE reduced the levels of LPS-induced pro-inflammatory mediators including IL-6, PGE2, and TNF-α, alleviated the lung injury histologically, and down-regulated LPS-induced mRNA and protein levels of TLR4/NF-κBp65 in lung tissue. This study demonstrated that PE has the anti-inflammatory effects on LPS-induced ALI in rats through TLR4/NF-κBp65 signaling pathway, indicating that PE is an effective suppressor for anti-inflammatory activities.

Effects of Shuanghuanglian oral liquids on patients with COVID-19: a randomized, open-label, parallel-controlled, multicenter clinical trial / 医学前沿

We conducted a randomized, open-label, parallel-controlled, multicenter trial on the use of Shuanghuanglian (SHL), a traditional Chinese patent medicine, in treating cases of COVID-19. A total of 176 patients received SHL by three doses (56 in low dose, 61 in middle dose, and 59 in high dose) in addition to standard care. The control group was composed of 59 patients who received standard therapy alone. Treatment with SHL was not associated with a difference from standard care in the time to disease recovery. Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group (93.4% vs. 73.9%, P = 0.006). Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia, which was evaluated by density reduction of inflammatory focus from baseline, at day 7 (mean difference (95% CI), -46.39 (-86.83 to -5.94) HU; P = 0.025) and day 14 (mean difference (95% CI), -74.21 (-133.35 to -15.08) HU; P = 0.014). No serious adverse events occurred in the SHL groups. This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.

Research on revision of origins to Chinese medicinal materials in 2020 edition of Chinese pharmacopoeia / 中国中药杂志

The origins of 9 species of the Chinese medicinal materials in the 2015 edition of the Chinese pharmacopoeia(ChP) has revised in the 2020 edition of ChP. The revision is based on the investigation and textual research on the problems found after screening the original plants, animals or minerals of all the Chinese medicinal materials in the 2015 edition. Among them the Chinese names of Alismatis Rhizoma, Cassiae Semen, Coicis Semen, Corydalis Bungeanae Herba and Echinopsis Radix all do not match to the Latin scientific names, and also do not match the name of the actual medicinal origins. In addition, Alismatis Rhizoma has the omission of original plant. There is confusion about the Chinese name and the family name of the original insect of Cera Chinensis. The original mineral of Gypsum Fibrosum has the wrong group names. Alumstone and melanterite, the original mineral of Alumen and Melanteritum respectively, of which the group names are missing. To solve these problems, field survey and literature research were conducted on the medicinal materials and their origins. The source of these problems are explored. The correct origins and the Chinese names or Latin names are all determined according to the research results to the situation, in which the Chinese and Latin names of the original plants of the medicinal materials do not match. The correct family name and group name are obtained through textual research by taxonomy if the names are confused or mis-sing. The scientific evidence and correct results of revision in the 2020 edition of ChP are determined at last.

And there are also negatives trials as following: individual mechanical ventilation, maximal recruitment open lung ventilation or early neuromuscular blockade for moderate-to-severe ARDS, N95 respirators preventing influenza, flexible family visit program against delirium or early sedation with dexmedetomidine to mechanically ventilated patients, intensive care unit (ICU) diary or nurse-led preventive psychological intervention against posttraumatic stress disorder (PTSD) in patients with mechanical ventilation, recombinant human soluble thrombomodulin (rhsTM) in patients with sepsis-associated coagulopathy, and so on. Further investigations should be focus on the phenotype analysis, by which individualized management fitting for specific pathophysiologic and immune characters for each patient could be clarified.

Antioxidant and Antiapoptotic Polyphenols from Green Tea Extract Ameliorate CCl-Induced Acute Liver Injury in Mice / 中国结合医学杂志

OBJECTIVE@#To investigate the phenolic composition, antioxidant properties, and hepatoprotective mechanisms of polyphenols from green tea extract (GTP) in carbon tetrachloride (CCl)-induced acute liver injury mouse model.@*METHODS@#High-performance liquid chromatography was used to analyze the chemical composition of the extract. Antioxidant activity of GTP was assessed by O, OH, DPPH, and ferric-reducing antioxidant power (FRAP) assay in vitro. Sixty Kunming mice were divided into 6 groups including control, model, low-, medium-, and high-doses GTP (200, 400, 800 mg/kg) and vitamin E (250 mg/kg) groups, 10 in each group. GTP and vitamin E were administered at a level of abovementioned doses twice per day for 7 days prior to exposure to a single injection of CCl. Hepatoprotective effects of GTP were evaluated in a CCl-induced mouse model of acute liver injury, using commercial enzyme linked immunosorbent assay kits, histopathological observation, terminal deoxynucleotidyl transferase-mediated dUTPNick-end labeling (TUNEL) assay and Western blot.@*RESULTS@#GTP contained 98.56 µg gallic acid equivalents per milligram extract total polyphenols, including epicatechingallate, epigallocatechin gallate, epicatechin, and epigallocatechin. Compared with the model group, low-, medium-, or high doses GTP significantly decreased serum levels of alanine aminotransferase and aspartate transaminase (P<0.01). Histopathological observation confirmed that pretreatment of GTP prevented swelling and necrosis in CCl-exposed hepatocytes. Hepatoprotective effects of low-, medium-, and high-dose GTP were associated with eliminating free radicals and improving superoxide dismutase, catalase, and glutathione peroxidase activity in the liver. Additionally, low-, medium-, and high-dose GTP decreased cell apoptosis in the CCl-exposed liver (P<0.01). Phosphorylated nuclear factor kappa-B (NF-κB), p53, Bcl-2 associated x protein/B-cell lymphoma/leukemia-2 gene, cytochrome C, and cleaved caspase-3 levels were downregulated compared with the model group (P<0.01).@*CONCLUSION@#GTP achieves hepatoprotective effects by improving hepatic antioxidant status and preventing cell apoptosis through caspase-3-dependent signaling pathways.

Method::Fifty-six SD rats were randomly divided into seven groups: control group, AR group, LSQDS AR group, BMD low dose two weeks group and four weeks group, BMD high dose two weeks group and four weeks group. The control group did not intervened, the AR group established the AR disease model with ovalbumin (OVA) as the allergen, the other five groups established the LSDQS model with smoke and senna gavage, and also established the AR disease model with OVA sensitization at the same time as the AR group. After the model was established successfully, four BMD intervention groups were separately given low dose BMD (11.3 g·kg-1) for 2 weeks and 4 weeks, and high dose BMD (22.6 g·kg-1) for 2 weeks and 4 weeks. To observe the general situation of the rats, hematoxylin eosin (HE) staining was used to observe the pathological changes of the nasal mucosa, immunohistochemistry and Western blot were used to detect the expression levels of NF-κB and AQP5, real-time fluorescent quantitative polymerase chain reaction technique (Real-time PCR)was used to detect mRNA levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6). Result::The typical AR symptoms were found in AR rats, the AR symptoms and lung and spleen Qi deficiency symptoms were found in AR rats with LSQDS at the same time, and the AR symptoms and lung and spleen Qi deficiency symptoms were significantly improved after the intervention of BMD. Compared with the control group, the typical histopathological changes of nasal mucosa were found in AR group and LSQDS AR group, with a higher behavioral score (P<0.05), and the expression of NF-κB and AQP5 protein increased (P<0.05), the expression of IL-1β, TNF-α, IL-6 and AQP5 mRNA increased (P<0.05). Compared with AR group, the pathological changes of nasal mucosa in LSQDS AR group were more serious, and the expression of NF-κB protein in nucleus increased (P<0.05), the expression of TNF-α and AQP5 mRNA increased (P<0.05). Compared with LSQDS AR group, the pathological changes of nasal mucosa in the groups which interfered by BMD were improved, and the expression of NF-κB and AQP5 protein decreased (P<0.05), the expression of IL-1β, TNF-α, IL-6 and AQP5 mRNA decreased (P<0.05). Compared with BMD low-dose two-week group, the expression of NF-κB protein in nucleus decreased (P<0.05) in BMD high dose four week group. Conclusion::Compared with AR group, the AR condition of the rats with LSQDS is more serious under the same allergen stimulation, BMD can treat AR and reduce the over secretion of glands, which may be related to inhibit the expression of AQP5 by inhibiting the NF-κB signaling pathway.

Effect of Shaolin internal qigong exercise on the surface electromyography signals of shoulder muscle groups in patients with capsulitis of the shoulder / 针灸推拿医学（英文版）

Objective: To unveil the efficacy of Shaolin internal qigong exercise in treating capsulitis of the shoulder (CS) and explore objective outcome measures by observing the changes in the surface electromyography (sEMG) signals of shoulder muscle groups after regular practice of Shaolin internal qigong exercise in CS patients. Methods: Sixty CS patients were randomized into two groups by the random number table method, with 30 cases in each group. Patients in the qigong group practiced Shaolin internal qigong exercise on a regular basis, while patients in the electroacupuncture (EA) group received EA treatment. Before and after treatment, the sEMG signals of six muscles, i.e. biceps brachii, triceps brachii, deltoid, pectoralis major, latissimus dorsi and trapezius muscles, of the affected side were recorded at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed during maximal isometric contraction, and the integrated electromyography (iEMG) of each muscle was calculated. Results: The total effective rate was 93.3％ in the qigong group, higher than 83.3％ in the EA group (P<0.05). Intra-group comparison showed that the iEMG of biceps brachii, triceps brachii, pectoralis major and deltoid muscles in the qigong group increased significantly after intervention at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed (all P<0.05), and the iEMG of trapezius and latissimus dorsi muscles decreased (both P<0.05); in the EA group, the iEMG of biceps brachii, pectoralis major and deltoid muscles increased significantly during contraction (all P<0.05), while the iEMG of triceps brachii, trapezius and latissimus dorsi muscles had no significant changes (all P>0.05). After intervention, there were significant differences in the iEMG of most of muscles between the two groups (all P<0.05), except for the iEMG of deltoid muscle at 45° of abduction of the shoulder joint during isometric contraction (P>0.05). Conclusion: Shaolin internal qigong exercise can effectively increase the motion intensity of the biceps brachii, triceps brachii, pectoralis major and deltoid muscles and reduce the compensation of the latissimus dorsi and trapezius muscles in CS patients; compared with EA, it produces a better result in improving the coordination and stability in shoulder joint movements.

OBJECTIVE@#To retrospectively analyze the results of treatment outcome by surgery combined with 125I brachytherapy and correlative factors of adenoid cystic carcinoma (ACC).@*METHODS@#In the study, 75 patients with primary ACC of oral and maxillofacial region were treated by surgery combined with 125I seeds brachytherapy. Radical resection or subtotal resection was applied for the tumor. The brachytherapy treatment planning system was used to create implant plans with the prescribed dose of 60 Gy to 120 Gy. The 125I seeds were implanted intraoperatively or postoperatively. The regular follow-up was required. The Kaplan-Meier method was used to assess the tumor control rate and the patients' survival rates. Meanwhile, the Cox regression analysis was used to find out the prognostic factors.@*RESULTS@#Local control rates at the end of 3 and 5 years were as follows: T1-T2, 92.2% and 82.0%; T3-T4, 82.6% and 82.6%; and overall, 90.0% and 78.8%. The disease-free survival rates were 74.9% and 54.3%, respectively. The overall survival rates for all the patients were 86.0% and 79.6%, respectively at the end of 3 and 5 years and were 91.3% and 91.3% for T1-T2 patients vs. 73.9% and 59.7% for T3-T4 patients. Distant metastasis-free survival rates at the end of 3 and 5 years were 84.4% and 76.7%, respectively. The distant metastasis-free survival rates at the end of 3 and 5 years were 83.4% and 79.6% with T1-T2 lesion compared with 86.0% and 67.8% with T3-T4 lesion. According to the COX univariate analysis and multivariate analysis, the risk of local recurrence would be raised by the age. Tumor stage and tumor site were the prognostic factors of the overall survival rates.@*CONCLUSION@#125I brachytherapy conducted as an adjuvant therapy postoperatively of ACC of oral and maxillofacial region can acquire satisfactory localregional control, distant metastasis-free survival, disease-free survival and overall survival. Tumors are prone to recur on the older patients. Patients having advanced tumor stage or tumor located in the nasal cavity or sinuses will suffer lower survival rates.

In the sham-operation group, the right common carotid artery was separated and no more management was given. In the EA preconditioning group, EA at "Baihui" (GV 20), "Shenshu" (BL 23) and "Sanyinjiao" (SP 6) was provided before modeling, with disperse-dense wave, at 2 Hz/100 Hz, 1 mA in intensity. The stimulation for 15 min was taken as one unit (meaning electric stimulation for 10 min and needle retaining for 5 min without electric stimulation). Such preconditioning was repeated continuously for 4 times, totally for 1 h. The neuroethologic condition was assessed in 3 h of reperfusion in each group. TTC staining method was used to determine the percentage of cerebral infarction zone, TUNEL method was to determine the apoptosis index (AI) in hippocampal neuron and the immunohistochemical method (IHC) was to determine the protein expression of p53 and caspase-3.@*RESULTS@#Compared with the sham-operation group, the neuroethologic score, the percentage of cerebral infarction zone and neuronal AI were all increased obviously in the ischemia-reperfusion group (all <0.01). Compared with the ischemia-reperfusion group, the neuroethologic score, the percentage of cerebral infarction zone and neuronal AI were all reduced obviously in the EA preconditioning group (all <0.01). p53's nuclei and caspase-3's cytoplasms were stained. The positive cells of both of them were brown-yellow in color. In the sham-operation group, the structure of the right hippocampal CA3 neurons of rats was clear, with few positive cells. In the ischemia-perfusion group, the positive expressions of p53 and caspase-3 in the right hippocampal CA3 were increased obviously (<0.01). Compared with the ischemia-reperfusion group, the positive expressions of caspase-3 and p53 in the right hippocampal CA3 were significantly reduced in the EA preconditioning group (<0.01).@*CONCLUSION@#Electroacupuncture preconditioning relieves ischemic injury in brain tissue of rats probably through inhibiting the expressions of p53 and caspase-3 to resisting neuronal apoptosis.

Antibiotics use and drug resistance analysis of neurology patients' Infection.

Recent studies have shown that nosocomial infection is an important factor affecting the quality and service level of neurology. Based on the characteristics of neurology patients, the application of antibacterial drugs has certain particular characteristic. In this paper, we analyzed the distribution of pathogenic bacteria in neurology patients in 2016-2017 year, and made statistics on the utilization of antibiotics. The results showed that 84 strains of pathogenic bacteria were isolated from the neurology department, including Gram-negative bacteria (44 strains, 52.38%), Gram-positive bacteria (31, 36.9%), and fungi (9, 10.71%). At the same time, as for the use of antibiotics, the drug category is most cephalosporins and the top 5 antiseptic drugs are cephalosporins, beta lactamase inhibitors, quinolones, aminosides and penicillins. The highest DUI (drug utilization index) value was for cefoperazone tazobactam (1.33), followed by ceftriaxone Mino (1.20) and ciprofloxacin (1.18). Clinicians should guide the selection of antimicrobial agents based on the results of etiological examination, and formulate a reasonable treatment plan based on the characteristics of patients, common pathogens and drug resistance.
