ABSTRACT
Based on the introduction of gut-brain-skin axis, this article discussed the relationship between psychological behavior, intestinal flora, and atopic dermatitis. By combing the literature on the treatment of atopic dermatitis with TCM, it is found that TCM therapy can regulate the relative abundance of intestinal flora, participate in immune metabolism and restore skin barrier function by intervening in the gut-brain-skin axis, so as to achieve the purpose of treating atopic dermatitis.
ABSTRACT
COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.
ABSTRACT
ObjectiveTo investigate the analgesic action and mechanism of intrathecal 2R, 6R-hydroxynorketamine (2R, 6R-HNK) on spared nerve injury (SNI)-induced chronic neuropathic pain (CNP) in female mice. MethodsSNI was used to establish acute and chronic CNP models in female mice. The mice were randomly divided into different groups with administration of vehicle, 2R, 6R-HNK or S-ketamine (10 mg/kg intraperitoneal injection/i.p. or 7, 21 μmol/L intrathecal injection/i.t.) at 3 weeks after or 30 min/1 d before operation (n = 3 - 7 mice/group). The curative or preventive effect of 2R, 6R-HNK was evaluated by mechanical paw withdrawal threshold (PWT) and the analgesic efficiency. Finally, immunofluorescence and RT-PCR of dorsal root ganglion (DRG) and spinal dorsal horn (SDH) were used to explore the possible mechanisms. ResultsCompared with vehicle, intrathecal injection of 2R, 6R-HNK largely reversed SNI-induced bilateral mechanical allodynia in a delayed-and-dose-dependent way. Among them, 21 μmol/L 2R, 6R-HNK reached its maximum analgesic efficiency (75.32±7.69) % at 2 d. Pre-intrathecal delivery of 2R, 6R-HNK also delayed the development of bilateral mechanical hypersensitivity 2 - 3 d induced by SNI. Mechanically, 2R, 6R-HNK reversed not only the abnormal excitability of neurons in bilateral DRG and superficial SDH, but also the upregulation of calcitonin gene-related peptide (CGRP) and brain-derived nerve growth factor (BDNF) in DRG. ConclusionIntrathecal administration of 2R, 6R-HNK exerts an analgesic effect against CNP, probably via suppressing abnormal neuronal excitability in ascending pain pathway as well as down-regulating CGRP and BDNF expression in DRG neurons.
ABSTRACT
Objective To explore the predictive value of baseline serum electrolyte levels for adverse prognosis in patients with severe traumatic brain injury(sTBI)in Lanzhou Plateau Area.Methods A total of 210 sTBI patients admitted to our hospital were enrolled,and then divided into good progno-sis group(91 cases)and poor prognosis group(119 cases)according to clinical outcome.The clinical data and serum electrolyte levels were compared between the two groups.Multivariate logistic regres-sion analysis was used to analyze the influencing factors of poor prognosis,and ROC curve was plot-ted to analyze the predictive value of the influencing factors.Results There were significant differ-ences in diabetes,GCS score,serum calcium and magnesium levels between the two groups(P<0.05,P<0.01).Multivariate logistic regression analysis showed that diabetes(OR=3.483,95%CI:1.452-8.357),GCS score(OR=0.464,95%CI:0.3 6 3-0.594),hypocalcemia(OR=6.243,95%CI:3.353-11.626)and hypermagnesemia(OR=9.985,95%CI:1.251-19.701)were the influencing factors for poor prognosis of sTBI patients.ROC curve analysis showed that the AUC val-ue was 0.702(95%CI:0.635-0.763)in hypocalcemia and 0.565(95%CI:0.495-0.633)in hy-permagnesemia for the prediction.Conclusion Diabetes,low GCS score,hypocalcemia and hypermag-nesemia are risk factors for poor prognosis of sTBI patients at high altitude.Hypocalcemia has good predictive value in the prediction and can be used as an independent predictor.
ABSTRACT
Objective:To evaluate the effect of propofol on proliferation of neural stem cells (NSCs) in mice and the role of specificity protein-1 (Sp-1)-epidermal growth factor receptor (EGFR)-protein kinase B (Akt) signaling pathway.Methods:Primary NSCs harvested from both the cortices and hippocampus of C57BL/6 mouse embryos were identified by immunofluorescent staining of Nestin.NSCs at passages 3-6 were divided into 3 groups ( n=21 each) using a random number table method: normal saline control group (C group), propofol group (P group) and propofol plus Sp1 inhibitor plicamycin group (PP group). Propofol at a final concentration of 10 μmol/L was added in group P. Propofol at a final concentration of 10 μmol/L and plicamycin at a final concentration of 100 nmol/L were added in group PP.The equal volume of normal saline was added in group C. The medium was replaced after 6 h of incubation and the cells were continuously incubated.The proliferation of NSCs was assessed by direct cell counting at 24, 36, 48, 60 and 72 h after the end of treatment with drugs.At 6 h after the end of treatment with drugs, the expression of Sp1 and EGFR mRNA was detected by real-time fluorescent quantitative polymerase chain reaction, and the expression of Sp1, Akt and phosphorylated Akt (p-Akt) by Western blot. Results:Compared with group C, the count of NSCs was significantly increased at 48, 60 and 72 h after treatment with drugs, and the expression of EGFR mRNA, Sp1 protein and mRNA and p-Akt was up-regulated in group P ( P<0.05 or 0.01), and no significant change was found in each parameter in group PP ( P>0.05). Compared with group P, the count of NSCs was significantly decreased at 48 and 60 h after treatment with drugs, and the expression of EGFR protein and mRNA and p-Akt was down-regulated in group PP ( P<0.05 or 0.01). Conclusions:Propofol can promote the proliferation of NSCs, and the mechanism may be related to activation of Sp1-EGFR-Akt signaling pathway in mice.
ABSTRACT
【Objective】 To investigate the quality changes of suspended red blood cells (SRBCs) prepared from the blood of Tibetan high Hb population, and explore the availability and safety of blood collected from Tibetan high Hb population. 【Methods】 The voluntary blood donors were grouped according to the Hb concentration at the initial screening: female blood donors from Tibet Autonomous Region (>3 500 m) with Hb≥190 g/L and male blood donors with Hb≥210 g/L were classified as plateau high hemoglobin group. A total of 13 male blood donors from Tibet Autonomous Region were recruited. And the female blood donors (n=13) with Hb(115~165) g/L and male blood donors (n=12) with Hb(120~185) g/L from Chengdu were classified as control group. Whole blood of 200 mL specification was centrifuged to remove the plasma, and MAP additive solution was added to prepare SRBCs, then SRBCs were divided into four aliquots (50 mL/bag and stored at 4℃. Parameters as blood routine, free Hb and hemolysis rate were measured aseptically at day 1, 14, 21, 35 of storage. And 10 mL SRBCs was used to extract membrane proteins for tyrosine phosphorylation detection of band 3 protein. 【Results】 The RBCs counts(×1012/L), hematocrit(%) and hemoglobin(g/L) of Tibetan high Hb group and control group were 6.76±0.95 vs 4.65±0.52, 63.3±6.8 vs 43.1±4.4 and 214.4±19.8 vs 143.2±16.9 (P<0.01). The erythrocyte deformability test on the day 1, 14, 21, 35 of storage showed that the deformability of SRBCs prepared from Tibetan high Hb group was significantly lower than that of the control group under shear stress of 3, 5.33, 9.49, 16.87, and 30 Pa, while the hemolysis rate of SRBCs prepared from the Tibetan high Hb group and the control group on the day 1, 14, 21, 35 were 0.050 2±0.040 2 vs 0.022 2±0.011 1, 0.055 4±0.043 vs 0.032 1±0.028 7, 0.061 2±0.025 9 vs 0.034 3±0.031 7 and 0.069 6±0.032 0 vs 0.044 0±0.033 3 (P<0.05). Western blotting showed that the cytoplasmic N-terminal Y21 of band 3 protein of SRBCs prepared from Tibetan high Hb group was highly phosphorylated. 【Conclusion】 The deformability of SRBCs prepared from the Tibetan high Hb group was significantly lower while the hemolysis rate of SRBCs was higher than that of the control group. The hemolysis rate of the SRBCs at the end of storage prepared from the Tibetan high Hb group meets the requirements of the national standard GB18469-2012(<0.8%). The increase of hemolysis rate of SRBCs prepared from the Tibetan high Hb group was closely related to the phosphorylation of band 3 protein.

ABSTRACT
Objective:Through comprehensive evaluation and analysis of the quality of Liuwei Dihuang (LWDH) preparations from different manufacturers and combining factors such as production technology, the key factors in the quality control of LWDH preparations are explored to provide a reference for improving the quality control level of LWDH preparations. Method:Morroniside, loganin and paeonol as quality control markers of LWDH products were determined by high performance liquid chromatography (HPLC), the mobile phase was acetonitrile (A) -0.3% phosphoric acid aqueous solution (B) for gradient elution (0-5 min, 5%-8%A; 5-20 min, 8%A; 20-35 min, 8%-20%A; 35-45 min, 20%-60%A; 45-55 min, 60%A), the detection wavelength of paeonol was at 274 nm, and the detection wavelengths of morroniside and loganin were at 240 nm. The quality characteristics of LWDH preparations with different dosage forms (big candied pills, water-honeyed pills, concentrated pills, hard capsules and soft capsules) from different manufacturers were analyzed. Combined these results with their actual production processes, the key-points of quality control in the whole production process were discussed. Result:The contents of three index ingredients in 128 batches of LWDH preparations were all in conformity with the standards of the 2015 edition of <italic>Chinese Pharmacopoeia</italic>, however, the content limit of some dosage forms in the current standard was unreasonable. For example, although the daily dose of crude drugs for big candied pills were almost twice the dose of water- honeyed pills (15.00, 8.57 g, respectively), they got exactly the same daily limits of the contents for both the quality markers. What′s more, these two formulations had the same process, so the differences between the process obviously could not be the reason of these differences. Conclusion:It is recommended that for the products with different dosage forms should have a similar content limits, if there are no obvious distinctions between their production processes. Which may benefit the quality control of the products with multi-dosage forms. The research on the quality standards of proprietary Chinese medicines should deeply study the existing characteristics of the quality standards, and fully respect the laws of the quality attributes of traditional Chinese medicines and the rules of the production process of Chinese patent medicines.

The BALB/c mice were immunized with homologous and heterologous immune strategies. The numbers of splenic lymphocytes secreting IFN-γ were measured by ELISPOT assay, meanwhile SIV gp120 antibody titer were measured by ELISA assay. Results:SIVenvT protein was expressed effectively by rAd5F35-SIVenvT and rMVA-SIVenvT in HEK293 cells. The specific immune response reached its peak at 4-week post first immunization, then decreased. SIV Env specific cellular immune response and SIV gp120 specific antibody could be detected at 4-16 weeks post first immunization. The specific cellular response was significant stronger in heterologous immunization group than homologous group at 4 week and 16 week. Furthermore, heterologous immunization induced significant higher titer of SIV gp120 antibody at 4 week than homologous group.Conclusions:Specific immune response induced by rAd5F35-SIVenvT in combination with rMVA-SIVenvT was stronger than homologous vector immunization. The results provided references for further study in nonhuman primates.
ABSTRACT
Blastocystis hominis is a parasite that parasitizes in the intestines of humans and animals, and is closely related to a variety of gastrointestinal diseases such as abdominal pain and diarrhea. B. hominis is distributed worldwide, and the prevalence of B. hominis infections and dominant subgenotypes vary in countries and in regions from the same country. This paper reviews the global prevalence of B. hominis human infections, its subtypes and geographical distribution, so as to provide insights into the understanding of the global epidemiology of B. hominis and the management of B. hominis infections.
ABSTRACT
Blastocystis hominis is a common parasitic protozoa in human and animal intestines; however, its pathogenicity remains controversial. Construction of animal models is of great significance to investigate the pathogenicity, pathogenic mechanisms and drug screening of B. hominis. Experimental animals, mode of infections, parasite strains and host immune status are important factors affecting the successful modeling of B. hominis infections in animals. Hereby, we review the progress of researches on animal models of B. hominis infections, and summarize the influencing factors and application of animal models of B. hominis infections, in order to provides insights into the selection of animals models of B. hominis infections.
ABSTRACT
Objective:To explore the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) on upper limb motor function in hemiplegic patients after stroke. Methods:From August, 2018 to July, 2019, 60 patients with hemiplegia after stroke were randomly divided into control group (n = 30) and observation group (n = 30). Both groups received conventional treatment. The observation group accepted 5 Hz rTMS to ipsilesional hemisphere premotor areas for three weeks. The control group received sham stimulation. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Brunnstrom stages, modified Ashworth Scale (MAS), modified Barthel Index (MBI) and Wolf Motor Function Test before and after treatment. Results:Two patients dropped in the control group. After treatment, the scores of FMA-UE, MBI and Wolf Motor Function Test improved in both groups (|t| > 3.686, P < 0.01), and the difference values of FMA-UE and Wolf Motor Function Test before and after treatment were more in the observation group than in the control group (|t| > 2.119, P < 0.05). Conclusion:High-frequency rTMS to ipsilesional hemisphere premotor areas could improve the recovery of upper limb and hand motor function in hemiplegic patients after stroke.
ABSTRACT
Objective:To study the effect of chair inclination angles forward on sit-to-stand time and muscle activation of lower extremities in stroke patients with hemiplegia. Methods:From January to August, 2019, 15 stroke patients with hemiplegia finished five times sit-to-stand at seat slope 0°, 10° and 20° forward. The time, and surface electromyogram (sEMG) signals of rectus femoris, hamstrings, anterior tibialis and peroneus muscle were recorded. Results:The total EMG peak, root mean square and integrated electromyography (iEMG) of all the muscles decreased at seat slope 10° and 20° forward compared with those at 0° (F > 4.530, P < 0.05). The time decreased at seat slope 20° forward compared with that at 0° (P < 0.05). Conclusion:Seat inclination forward at some angles may improve the sit-to-stand performance in stroke patients with hemiplegia.

ABSTRACT
Swiprosin-1 (also known as EFhd2) is one of the earliest adaptor proteins found in T lymphocytes. Subsequent studies have found that it is also expressed on macrophages, B lymphocytes, mast cells and other immune cells, and affects the activation, migration, apoptosis and inflammatory response of immune cells, and participates in many signaling pathways 9uch as NF-kB, JAK-STAT, MAPK and calcium signaling. This arti cle briefly reviews the role and mechanism of EFhd2 reported in the regulation of immune inflammatory response in recent years, and provides a theoretical basis for further clarifying EFhd2 as a potential target for new immune regulation.
ABSTRACT
Objective To evaluate the reliability and validity of the patient health questionnaire-9 (PHQ-9) in patients with acne.Methods A total of 300 patients with acne were enrolled from the Department of Dermatology,Affiliated Hospital of Southwestern Medical University from January 2017 to June 2018.Questionnaire survey was conducted among these patients to evaluate their depression status with the PHQ-9 and Hamilton depression scale (HAMD),and the questionnaire completion time was recorded.The structured clinical interview (SCID) for American Diagnostic and Statistical Manual of Mental Disorders (4th Version) (DSM-Ⅳ) served as the "gold standard" for diagnosis of depression.Reliability analysis of the PHQ-9 was performed using the Cronbach's α coefficient and one-week testretest reliability.Factor analysis,Spearman correlation analysis and receiver operating characteristic (ROC) curve were used for validity analysis of the PHQ-9,and the screening validity was also analyzed in different subgroups.Results A total of 258 patients with acne completed all the survey,and 47 were diagnosed with depressive disorder according to the diagnostic gold standard SCID.An optimal cutoff score of 9 was determined for the diagnosis of depression using the PHQ-9,with a sensitivity of 95.7%,a specificity of 88.6%,and an area under the ROC curve (AUC) of 0.973 (95% CI:0.956-0.990).In different groups of people,the AUC ranged from 0.886 to 0.955.Validity analysis showed that the correlation coefficient between the total score of PHQ-9 and HAMD was 0.766,and the kappa value was 0.530.Factor analysis revealed that there were two common factors (cognitive-emotion factor and somatic symptom factor),which explained 65.52% of the total variances.As reliability analysis showed,the Cronbach's α coefficient of the PHQ-9 was 0.851,the correlation coefficients of the 9 items with the total scale score ranged from 0.550 to 0.709,the inter-item correlation coefficients ranged from 0.224 to 0.654,and the test-retest reliability value of the PHQ-9 was 0.824.The time to complete the PHQ-9 (4.9 ± 1.2minutes) was significantly less than the time to complete HAMD (44.2 ± 5.9 minutes;t =108.787,P <0.001).Conclusions The PHQ-9 shows good reliability and validity for the diagnosis of depression in patients with acne,and can be used for preliminary screening of depression in patients with acne.Compared with the HAMD,the PHQ-9 has obvious advantages of being more timesaving and manpower-saving to make it easier to implement in clinic.
