ABSTRACT

ObjectiveTo retrospectively analyze the clinical data of 52 patients with coronavirus disease-2019 (COVID-19) and explore the clinical efficacy of modified Sanxiaoyin on mild/moderate COVID-19 patients. MethodThe propensity score matching method was used to collect the clinical data of mild or moderate COVID-19 patients enrolled in the designated hospital of the Second Hospital of Jingzhou from December 2019 to May 2020. A total of 26 eligible patients who were treated with modified Sanxiaoyin were included in the observation group, and the 26 patients treated with conventional method were the regarded as the control. The disappearance of clinical symptoms, disappearance time of main symptoms, efficacy on traditional Chinese medicine (TCM) symptoms, hospitalization duration, laboratory test indicators, and CT imaging changes in the two groups were compared. ResultThe general data in the two groups were insignificantly different and thus they were comparable. After 7 days of treatment, the disappearance rate of fever, cough, fatigue, dry throat, anorexia, poor mental state, and poor sleep quality in the observation group was higher than that in the control group (P<0.05), and the difference in the disappearance rate of expectoration and chest distress was insignificant. For the cases with the disappearance of symptoms, the main symptoms (fever, cough, fatigue, dry throat, anorexia, chest distress) disappeared earlier in the observation group than in the control group (P<0.01). After 7 days of treatment, the scores of the TCM symptom scale of both groups decreased (P<0.01), and the decrease of the observation group was larger that of the control group (P<0.01). All patients in the two groups were cured and discharged. The average hospitalization duration in the observation group [(12.79±2.68) d] was shorter than that in the control group [(15.27±3.11) d] (P<0.01). The effective rate in the observation group (92.31%, 24/26) was higher than that in the control group (76.92%, 20/26) . After 7 days of treatment, the lymphocyte (LYM) count increased (P<0.05), and white blood cell (WBC) count and neutrophil (NEUT) count decreased insignificantly in the two groups. Moreover, levels of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and procalcitonin (PCT) reduced in the two groups after treatment (P<0.01) and the reduction in the observation group was larger than that in the control group (P<0.01). Through 7 days of treatment, the total effective rate on pulmonary shadow in the observation group (90.00%, 18/20) was higher than that in the control group (77.27%, 17/22) (P>0.05) and the improvement of lung shadow in the observation group was better than that in the control group (P<0.01). ConclusionModified Sanxiaoyin can significantly alleviate fever, cough, fatigue, anorexia, chest distress, poor sleep quality, and other symptoms of patients with mild or moderate COVID-19, improve biochemical indicators, and promote the recovery of lung function. This paper provides clinical evidence for the application of modified Sanxiaoyin in the treatment of mild or moderate COVID-19.

ABSTRACT

The decreased efficacy and severe side effects of antibiotics, as well the increase of multidrug resistant pathogens are seriously threatening human health. It has become an urgent task for the whole world to actively respond to threats and establish effective prevention and control plans. Traditional Chinese medicine (TCM) has a long history with exact curative effect in the treatment of infectious diseases. It not only inhibits pathogens and eliminates endotoxin, but also has therapeutic effect on inflammation, immune abnormality and overall disorder caused by infection. Antibiotics mainly inhibit the pathogen itself, while the combination of TCM and antibiotics is complementary with each other and is considered as a feasible solution to the challenges. Some clinical observations have shown that TCM has potentiality of enhancing antibiotics efficiency and reducing toxicity. Exploring its mechanism is the necessary measure to optimize and popularize treatment regimen. Firstly, multi-level and multi-dimensional systematic pharmacology network analysis methods are used to predict the mechanism of TCM combined with antibiotics in the treatment of infectious diseases, so as to provide the evidence for further empirical research and selection of test indicators. Then by following the principle of corresponding drug use in specific TCM syndromes, the antibiotics and TCM are individually and jointly applied to treat patients with specific syndrome conditions of infectious diseases. Besides routine and comprehensive evaluation of synergistic and attenuated effect of the combined drug use, multi-omics technique is also used to find the subtle effects of these two drugs at a molecular level. The sensitive and stable clinical biomarkers of synergism and attenuation of combined drug use are determined by using biomolecular network analysis technology. Finally, taking these biomarkers as clues, the biotransformation process and regulation mechanism of the biomarkers are traced back in animal models of infectious diseases and cell level, and all of these are clinically verified. As a result, the mechanism of efficacy enhancing and toxicity reducing of combined drug use can be revealed, providing basis for the promotion and application of such combined drug use.

ABSTRACT

Objective To evaluate the effect of cardiopulmonary bypass (CPB) on the expression of hypothalamic nerve growth factor precursor (proNGF) and the influence of hypothalamic proNGF on the sympathetic output of paraventrucular nucleus. Methods Forty-two male SD rats, aged 3-4 months, weighing 350-500 g, were divided into control group, CPB group and ischemia reperfusion (IR) group. At the end of CPB for 110 min, hypothalamus and dorsal root ganglion (DRG) were taken to measure the levels of proNGF mRNA and hypothalamic proNGF protein. Mini pipe was put into bilateral paraventrucular nucleus (PVN) and human recombination proNGF protein was injected into PVN for 7 d before the local field potentials (LFP) of RVLM was recoreded. Human recombination proNGF protein was administrated into lateral ventricle, the prior-administration-LFP of PVN and post-administration-LFP were recorded and compared. At the end of the experiment, hypothalamus was taken to measure the levels of glutamate and gammer amino butyric acid (GABA). Results Hypothalamic proNGF protein in CPB group and IR group was higher than that in the control group (P < 0.05); NGF mRNA of hypothalamus and DRG in CPB and IR group were higher than those of control group (P < 0.05). In PVN and RVLM, after the administration of proNGF protein, the power of delta band significantly decreased and other bands increased (P < 0.05). The hypothalamic GABA level decreased (P < 0.05) with no change of hypothalamic glutamate after proNGF was injected into lateral ventricle. Conclusion CPB increases the expression of proNGF in the hypothalamus contributing to the changes of hypothalamic sympathetic output.

ABSTRACT

BACKGROUND: This study evaluated the effect of decrease in loading dose administration rate of dexmedetomidine (DMT) on sedation and DMT requirement in elderly patients. METHODS: Fifty-eight patients over 65 years old with ASA I–II who were planned to receive DMT sedation during spinal anesthesia were randomly assigned to two groups. Group S (n = 29) received a 0.5 µg/kg DMT loading dose over 20 minutes, while group C (n = 29) received the DMT loading dose over 10 minutes. Then, both groups received a continuous infusion of 0.4 µg/kg/h. The sedative status was recorded before and at 5, 10, 15, 20, 25, and 30 minutes after administration of DMT and at the end of the anesthesia according to the Ramsay sedation scale (RSS). Also, the time to reach RSS-3 (patients asleep, responsive to commands) and the dose of DMT until reaching RSS-3 were recorded. RESULTS: The time to reach RSS-3 was similar between the two groups (group S = 16.0 ± 4.3 minutes vs. group C = 15.5 ± 4.2 minutes, P = 0.673). However, the DMT required to reach RSS-3 in group S was significantly lower than that in group C (23.3 ± 7.1 vs. 32.5 ± 6.0 µg, P < 0.001). There was no difference in RSS between the two groups from the administration of DMT to the end of the anesthesia (P = 0.927). CONCLUSIONS: Decreasing the administration rate of the DMT loading dose did not delay the onset of RSS-3 sedation and reduced the DMT requirement in elderly patients.

ABSTRACT

Tissue biopsy is a diagnostic standard as well as the targeted therapy of cancer. However, tissue biopsy has some limitations in the cancer diagnosis , assessment of cancer development, prognosis and genotyping due to tumor heterogeneity and evolution. Circulating tumor DNA (ctDNA) is a kind of circulating DNA fragments released by the tumor cells into the circulation system reflecting the state of tumors. With the emergence of new technology, the ways to detect the specificity and sensitivity of ctDNA have been improved greatly. Furthermore, detection of ctDNA could analyze oncogene and epigenetic changes, which has been widely used in molecular subtyping, assessment of tumor dynamic and burden, evaluation of minimal residual disease and recurrence, prognosis assessment, monitoring of drug resistance and exploration of new therapeutic targets.

ABSTRACT

<p><b>BACKGROUND</b>It has found that ischemic postconditioning (IPO) might decrease pulmonary ischemia/reperfusion (I/R) injury, which is one of the main reasons of lung injury caused by cardiopulmonary bypass (CPB). It was found that aquaporins (AQPs) play a role in the maintenance of fluid homeostasis. But it is still unclear whether IPO influences the expression of aquaporin-1 (AQP1). This study was designed to investigate whether IPO can reduce CPB-related lung injury and affect the expression of AQP1 of lungs.</p><p><b>METHODS</b>Twelve healthy dogs were divided into control group (C group) and ischemia postconditioning group (IPO group). CPB procedures were implemented. Ten minutes later, the left pulmonary artery was separated and blocked. Postconditioning consisted of two cycles of 5-minute pulmonary artery reperfusion/5-minute reocclusion starting at the beginning of reperfusion. The 2×4 cm tissues of both sides of pulmonary apex, superior, middle and inferior lobe were taken before CPB (T1), before occlusion and reopening of left pulmonary artery (T2, T3), and 2 hours after CPB (T4). Samples were used to evaluate lung injury degrees and to detect the expression of AQP1. At T1 and T4, blood was collected from femoral artery to calculate pulmonary function.</p><p><b>RESULTS</b>At T4, each pulmonary function showed significant deterioration compared with T1. Lung injury could be found at the onset of CPB. However, the expression of AQP1 decreased and wet to dry weight ratio (W/D) increased after T2. In the left lung of C group, the worst pulmonary function and structures were detected. The slightest changes were discovered in the right lung of C group. A close relationship between W/D and lung injury score was found. The lung injury score was negatively related with the expression of AQP1. It was found that the expression of AQP1 was negatively connected with W/D.</p><p><b>CONCLUSIONS</b>In dog CPB models, lung injury induced by CPB was related with down regulated expression of AQP1. AQP1 is believed to be involved in the mechanisms of lung ischemia/reperfusion (I/R) injury caused by CPB. IPO increases the expression of AQP1, provides a protective effect on lung suffering from CPB, and alleviates CPB-related lung injury.</p>

ABSTRACT

The present paper was aimed to study the security of burning during the continuous monitoring of transesophageal arterial oxygen saturation. 20 rabbits were randomly divided into two groups: control group and high-frequency electrotome group. All rabbits were implanted with the oxygen saturation detection probes into the lower esophageal after anesthesia. The probes were made up with two light-emitting diode (LED) and then connected with oxygen saturation sensor to monitoring for 2h and 6h, respectively. We then intercepted two luminous points as esophageal specimens and dist the esophageal tissue detection device headend 1cm gastric side esophageal specimens (self-contr01) after monitoring, and carried out pathological examination. The pathological results of the LED-1, LED-2 esophageal biopsy and self-control section were mucous integrity, submucosal mildedema, hyperemia, a small number of lymphocytes and mononuclear cell infiltration. All the score of the esophageal tissue histologic was 2. The results showed that montioring the SteO2 not more than 6h was safe with montiored using a matching of oxygen saturation sensor and monitoring esophageal arterial oxygen saturation.

ABSTRACT

Objective To investigate the effect of hypoxic postconditioning and diazoxide postconditioning on the calreticulin expression during hypoxia/reoxygenation (H/R) in rat cardiomyocytes. Methods Primary cultured male SD rat cardiomyocytes were randomly divided into 6 groups (n = 8 each): control group (group C),H/R group; hypoxic postconditioning group (group HP) and diazoxide postconditioning group (group DP). Group C were cultured continuously for 2 h. Group H/R, Hp and DP were exposed to 45 min hypoxia (95% N2-5% CO2)followed by 1 h reoxygenation. In group HP, the cells were subjected to three cycles of 3 min hypoxia at 3 min intervals at the end of 45 min hypoxia before 1 h reoxygenation. In group DP, diazoxide 50 μmol/L was giyen at the end of hypoxia. Caspase-3 activity, calreticulin expression and intracellular free calcium ion concentrations were determined. Results Compared with group C, caspase-3 activity was significantly increased in the other groups,the calreticulin expression was up-regulated in group HP and DP, and the free calcium ion concentrations were increased in group H/R (P < 0.05 or 0.01). Compared with group H/R, caspase-3 activity was significantly decreased in HP and DP, the calreticulin expression was up-regulated and the free calcium ion concentrations were decreased in group HP and DP (P < 0.01). Conclusion Hypoxic postconditioning and diazoxide postconditioning attenuate H/R injury in rat cardiomyocytes through up-regulating the expression of calreticulin and reducing intracellular calcium overload.

ABSTRACT

Objective To investigate the effect of hydrogen sulfide postconditioning on the systolic function of left ventricle during myocardial ischemia-reperfusion (IR) in rats. Methods Part Ⅰ Adult male SD rats weighing 200-250 g were anesthetized with pentobarbital 40 mg/kg and heparin 250 U/kg. Their hearts were excised and perfused in a Langendorff apparatus with K-H solution saturated with 95% O2-5% CO2 at 37 ℃. Forty isolated rat hearts were randomly divided into 5 groups ( n = 8 each) after 20 min of equilibration: control group (group C); IR group; sodium hydrosulfide 1,10, 100 μmol/L postconditioning group (group SP1, SP10, SP100 ).In group Cthe hearts were perfused continuously for another 100 min. In group IR, the hearts were reperfused for 60 min after 40 min ischemia induced by 10 ml/kg ST. Thomas solution. In group SP1 , SP10 and SP100 the hearts were perfused with K-H solution containing sodium hydrosulfide 1, 10, 100 μmol/L for 2 min before reperfusion.LVDP and ± dp/dtmax were recorded at the end of equilibration and reperfusion. Part Ⅱ Cardiomyocytes were isolated from the male SD rats (weighing 200-250 g) and then cultured in CO2 incubator for 4 h. Sixty-four dishes of cultured myocytes were randomly divided into 4 groups( n = 16 each): control group (group C), hypoxia/reoxygenation group (group HR), hydrogen sulfide postconditioning group (group SP) and hypoxia postconditioning group (group HP). Group C were cultured continuously for 2 h. Group HR, SP and HP were exposed to 1 h hypoxia (95%N2-5%CO2 ) followed by 1 h reoxygenation. In group SP 10 μmol/L sodium hydrosulfide was added and the myocytes were then incubated for 2 min before reoxygenation. In group HP the cultured myocytes were expased to 3 min reoxygenation followed by 3 min hypoxia for 3 times before the 1 h reoxygenation. Mitochondrial membrane potential and F-actin expression were determined. Results Part Ⅰ Compared with group C, LVDP and ± dp/dtmax were significantly decreased at the end of reperfusion in group IR (P < 0.05), while no significant difference was found in group SP1 , SP10 and SP100(P >0.05). Compared with group IR, LVDP and ± dp/dtmax were significantly increased in group SP ( P < 0.05). There was no significant difference in LVDP and ± dp/dtmax among group SP1, SP10 and SP100(P >0.05). Part H Compared with group C, the mitochondrial membrane potential was significantly decreased in group HR and HP, and the expression of F-actin was significantly up-regulated in group HR, SP and HP ( P < 0.05). Compared with group HR, the mitochondrial membrane potential was significantly increased and the expression of F-actin up-regulated in group SP and HP ( P < 0.05 ). There were no significant difference in the mitochondrial membrane potential and expression of F-actin between group SP and HP ( P >0.05).Conclusion Hydrogen sulfide postconditioning can improve left ventricular systolic function during IR in rats by stabilizing mitochondrial membrane potential and promoting aggregation of F-actin.

Objective To investigate the effects of Lp(a)on proliferation GMCs of rat model induced by lipopolysaccharide and explore the possible mechanism of Lp(a)in the proliferation of rat GMCs.Methods To observe the effects of Lp(a)on proliferation of GMCs,different dosage of Lp(a)were used,The research were divided into three groups:Control group,LPS group,Lp(a)group.After culture(at the end of 12h,24h,48h,60h and 72h),the cultured GMCs and suspension were collected to observe the rate of GMCs proliferation by MTT,the positive rate of proliferation cell nuclear antigen(PCNA)by immunohistochemisty,and the level of intercellular adhesion molecule-1(ICAM-1)by ELISA respectively.Results Compared with control and LPS group,MTT,positive rate of PCNA and ICAM-1 of GMCs were increased more significantly in Lp(a)group.MTT ,the positive rate of PCNA and ICAM-1 of GMCs were increased as Lp(a)dosage increased,a maximal effect was seen when Lp(a)was 2.5 μg/L or 5.0μg/L.When the dosage continue increased,MTT,the positive rate of PCNA and ICAM-1 activity of GMCs began to decrease in Lp(a)group.ICAM-1 showed positive correlation with MTT and the positive rate of PCNA.Conclusion Lp(a)can significantly affect the rate of GMCs proliferation,and this affection is in a dosage-and timedependent manner.Low dosage stimulates GMCs proliferation, and high dosage inhibits GMCs proliferation.ICAM-1 shows positive correlation with MTT and the positive rate of PCNA.The effect of Lp(a)on GMCs may be through ICAM-1.

ABSTRACT

<p><b>OBJECTIVE</b>To develop a safe and novel immunoadjuvant to enhance the immunity and resistance of animals against E. coli infection.</p><p><b>METHODS</b>An 88-base immunostimulatory oligodeoxynuleotide containing eleven CpG motifs (CpG ODN) was synthesized and amplified by PCR. The chitosan nanoparticle (CNP) was prepared by ion linking method to entrap the CpG ODN that significantly promotes the proliferation of lymphocytes of pig in vitro. Then the CpG-CNP was inoculated into 21-day old Kunming mice, which were orally challenged with virulent K88/K99 E. Coli 35 days after inoculation. Blood was collected from the tail vein of mice on days 0, 7, 14, 21, 28, 35, 42, and 49 after inoculation to detect the changes and content of immunoglobulins, cytokines and immune cells by ELISA, such as IgG, IgA, IgM, IL-2, IL-4, and IL-6.</p><p><b>RESULTS</b>The CpG provoked remarkable proliferation of lymphocytes of pig in vitro in comparison with that of control group (P < 0.05). The inoculation with CpG-CNP significantly raised the content of IgG, IgM, and IgA in the sera of immunized mice (P < 0.05). The levels of IL-2, IL-4, and IL-6 in the mice significantly increased in comparison with those in controls (P < 0.05), so was the number of white blood cells and lymphocytes in immunized mice. The humoral and cellular immunities were significantly enhanced in immunized mice, which resisted the infection of E. coli and survived, while the control mice manifested evident symptoms and lesions of infection.</p><p><b>CONCLUSIONS</b>CpG-CNP can significantly promote cellular and humoral immunity and resistance of mice against E. coil infection, and can be utilized as an effective adjuvant to improve the immunoprotection and resistance of porcine against infectious disease.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the regulating effects of a novel CpG oligodeoxynuleotide and the synergistic effect of chitosan-nanoparticles (CNP) with CpG on immune responses of mice, which were used to develop a novel immunoadjuvant to boost immune response to conventional vaccines.</p><p><b>METHODS</b>A novel CpG ODN containing 11 CpG motifs was synthesized and its bioactivities to stimulate the proliferation of lymphocytes of pig in vitro were detected. Then it was entrapped with CNP prepared in our laboratory by the method of ionic cross linkage, and immunized Kunming mice were co-inoculated with paratyphoid vaccine. The peripheral blood was collected weekly from the tail vein of inoculated mice to detect the contents of IgG, IgA, IgM, and specific antibody against salmonella as well as the levels of interleukin-2 (IL2), IL-4, and IL-6 by SABC-ELISA assay. The numbers of leucocytes, monocytes, granuloytes, and lymphocytes were calculated separately using the routine method. The experimental mice were orally challenged with virulent salmonella 35 days after inoculation.</p><p><b>RESULTS</b>This CpG ODN could remarkably provoke the proliferation of lymphocytes of pig in vitro in contrast with the control (P < 0.05). Compared with those of the control, immunoglobulins, including IgG, IgA, IgM, and specific antibodies to paratyphoid vaccine, increased significantly in sera from the CpG or CpG-CNP-vaccinated mice (P < 0.05). IL-2, IL-4, and IL-6 increased remarkably in sera from immunized mice (P < 0.05). The leucocytes, monocytes, granuloytes, and lymphocytes of the mice immunized with CpG or CpG-CNP were also increased in number (P < 0.05). After the challenge, these immunity values were elevated in the mice vaccinated with CpG or CpG-CNP. The immunized mice all survived, while the control mice fell ill with evident lesions with diffuse hemorrhage in stomach, small intestine, and peritoneum.</p><p><b>CONCLUSIONS</b>CpG ODN entrapped with CNP is a promising effective immunoadjuvant for vaccination, which promotes humoral and cellular immune responses, enhances immunity and resistance against salmonella by co-administration with paratyphoid vaccine.</p>
