Effects of pre-injection of pressors on pressor response and bispectral index of patients receiving lower abdominal surgery under total intravenous anesthesia

Surgery in the lower abdomen can cause many adverse reactions in nervous system, metabolic and endocrine systems. Conventional intravenous anesthesia applied for lower abdominal surgery can cause the drop in blood pressure leading to hypoperfusion of vital organs. Hence, an ideal anesthesia state is required to make patients unconscious, unaware and have no postoperative memory during anesthesia. In this study, we investigated the effects of pre-injection of different pressors on the pressor response and bispectral index (BIS) of patients receiving lower abdominal surgery under total intravenous anesthesia. For this, 300 patients undergoing lower abdominal surgery under total intravenous anesthesia were divided into normal saline (Gr. A), ephedrine (Gr. B) and phenylephrine groups (Gr. C) (n=100). Hemodynamics indices were recorded before anesthesia induction (T0) and 1, 3, 5, 7 and 9 min after drug injection (T1-T5, respectively). We observed the following reactions and recorded. BIS values at T0-T5 as well as the time points when the values rose to 65, 75, 85 and 95 and those for respiratory recovery, consciousness recovery and extubation after stopping target-controlled infusion were recorded. Compared with Gr. A, Gr. B had significantly higher systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR) and cardiac output (CO) at T1-T5 (P <0.05), and Gr. C had higher SBP, DBP, MAP and lower HR (P <0.05). Adverse reactions viz., intraoperative hypotension, hypertension, postoperative bradycardia, tachycardia, nausea and vomiting were also observed. The incidence rates of hypotension and total adverse reactions in groups B and C were significantly lower than those of Gr. A (P <0.05). Group B had significantly higher BIS values at T1-T5 than those of Gr. A (P <0.05). The time when BIS values recovered to 65 and 75 in group B was significantly shorter than that of Gr. A (P <0.05). Pre-injection of ephedrine and phenylephrine to patients undergoing lower abdominal surgery under total intravenous anesthesia elevated the blood pressure and reduced the incidence rate of adverse reactions without affecting the recovery time.

Integrating 16S sequencing and metabolomics study on anti-rheumatic mechanisms against collagen-induced arthritis of Wantong Jingu Tablet / 中国天然药物

Wantong Jingu Tablet (WJT), a mixture of traditional Chinese medicine, was reported to relieve the symptoms of rheumatoid arthritis (RA), but its pharmacological mechanism was not completely understood. The aim of this study was to investigate the therapeutic mechanisms of WJT for RA in vivo. The effects of WJT on joint pathology, as well as the levels of Bax, Bcl-2, caspase-3, cleaved-caspase-3, ERK1/2, pERK1/2, TNF-α, IL-1β, and IL-6 were measured using collagen-induced arthritis (CIA) rats. The intestinal flora composition and the metabolites alteration were analyzed by 16S rDNA sequencing and metabolomics method, respectively. We found that WJT ameliorated the severity of the CIA rats which might be mediated by inducing apoptosis, inactivating the MEK/ERK signals and reducing the production of pro-inflammatory cytokines. WJT, in part, relieved the gut microbiota dysbiosis, especially bacterial phylum Bacteroidetes, Tenericutes and Deferribacteres, as well as bacterial genus Vibrio, Macrococcus and Vagococcus. 3'-N-debenzoyl-2'-deoxytaxol, tubulysin B, and magnoline were significantly associated with the specific genera. We identified serotonin, glutathione disulfide, N-acetylneuraminic acid, naphthalene and thromboxane B2 as targeted molecules via metabolomics. Our findings contributed to the understanding of RA pathogenesis, and WJT played essential roles in gut microbiota health and metabolite modulation in the CIA rats.

ObjectiveTo clarify the medication regularity of WU Zhao-dong，a famous chief physician in traditional Chinese medicine （TCM） of Jiangxi province， and investigate the potential mechanism of potential new prescriptions against chronic renal failure （CRF）. MethodThe outpatient prescriptions of WU Zhao-dong from July 2019 to July 2021 were collected. Data mining was carried out by using the Traditional Chinese Medicine Inheritance Auxiliary Platform （V 2.5） to analyze the medication frequency and drug association and obtain potential new prescriptions. The interaction between drug targets in new prescriptions was analyzed by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP），STRING，and Kyoto Encyclopedia of Genes and Genomes（KEGG）， followed by verification by molecular docking and experiments. ResultA total of 200 prescriptions were screened out， with 217 Chinese medicinal drugs involved， and eight new potential prescriptions were derived. To be specific， Prescription 1： Armeniacae Semen Amarum-Astragali Radix-Platycodonis Radix-Angelicae Sinensis Radix-Smilacis Glabrae Rhizoma-fried Atractylodis Macrocephalae Rhizoma， Prescription 2： Saposhnikoviae Radix-Schizonepetae Herba-Kochiae Fructus-Asteris Radix et Rhizoma-Menthae Haplocalycis Herba，Prescription 3：Armeniacae Semen Amarum-Asteris Radix et Rhizoma-Platycodonis Radix-Eriobotryae Folium-prepared Ephedrae Herba， Prescription 4：Perillae Caulis-Codonopsis Radix-Coptidis Rhizoma-Pseudostellariae Radix， Prescription 5：Ecliptae Herba-Astragali Radix Praeparata Cum Melle-Dryopteridis Crassirhizomatis Rhizoma-Rosae Laevigatae Fructus-Coicis Semen-Ligustri Lucidi Fructus， Prescription 6： Lycopi Herba-Lonice Raejaponicae Caulis-Trachelospermi Caulis et Folium-Alismatis Rhizoma， Prescription 7：Scutellariae Radix-Hirudo-Paeoniae Radix Rubra-Eriobotryae Folium-Glehniae Radix， Prescription 8：Glycyrrhizae Radix et Rhizoma-Scrophulariae Radix-Chrysanthemi Indici Flos-Smilacis Glabrae Rhizoma- Serissae Herba. In Prescription 1，18 main chemical components were screened out. Eighty targets of active components of Prescription 1 were predicted， and 37 potential targets for the treatment of CRF were obtained， including interleukin （IL）-6， vascular endothelial growth factor （VEGF）， cysteinyl aspartate-specific protease-3 （Caspase-3）， nitric oxide synthase 3 （NOS3）， and hypoxia-inducible factor-1 （HIF-1）. The KEGG pathways involved in the targets of Chinese medicinal drugs and disease mainly included the signaling pathways of lipid and atherosclerosis，NF-κB， Toll-like receptors， and HIF-1. Prescription 1 significantly decreased serum creatinine and urea nitrogen， and increased the content of NO and NOS3 in renal tissues of CRF rats. ConclusionPrescription 1 shows the multi-component and multi-target characteristics of action，and its mechanism may be related to its inhibition of renal fibrosis，anti-inflammation，improvement of intestinal microecology，and improvement of renal hypoxia and ischemia.

α-Helical protein absorption at post-traumatic epileptic foci monitored by Fourier transform infrared mapping

Tissue analysis by Fourier transform infrared (FTIR) imaging can determine the biodistribution of molecules,without pre-analytical modification. We aimed to study the infrared spectroscopic changes of a-helical proteinsat post-traumatic epileptic (PTE) foci by FTIR. FITR mapping was applied to detect a-helical proteins in ratbrain tissue samples with post-traumatic epilepsy. Histological examination of brain sections showed that therat model of PTE was successfully established. At the PTE foci, high a-helical absorption regions wereevident, where the color difference and absorption were significantly different from those in the low-absorptionregions. This provided a distinctive and characteristic pattern at the site of lesions. The use of FTIR imagingmeans that it is possible to measure the molecular structural changes resulting from PTE pathologies in tissues,providing a novel adjunct to conventional pathological diagnostic techniques.

The application of Compont gel in chronic obstructive jaundice rats model

Abstract Purpose: To establish a new rat model, the pathogenesis of which is closer to the clinical occurrence of chronic obstructive jaundice with liver fibrosis. Methods: 90 SD rats were randomly divided into 3 groups. Group A common bile duct ligation, group B common bile duct injection compont and group C injection saline. The serum of three groups was extracted, and the liver function was detected by ELISA. HE staining, Masson staining and immunohistochemistry were used to detect liver pathology. Results: Group B showed a fluctuant development of jaundice, obstructive degree reached a peak at 2 weeks, and decreased from 3 weeks. HA, LA and PCIII were significantly higher than control group. 3 weeks after surgery, liver tissue fibrosis occurred in group B, and a wide range of fiber spacing was formed at 5 weeks. Immunohistochemistry showed that hepatic stellate cells were more active than the control group. Conclusion: Intra-biliary injection of Compont gel is different from the classic obstructive jaundice animal model caused by classic bile duct ligation, which can provide an ideal rat model of chronic obstructive jaundice with liver fibrosis.

Secondary Short-Lasting Unilateral Neuralgiform Headache with Conjunctival Injection and Tearing: A New Case and a Literature Review

Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a primary headache syndrome with an unclear pathogenesis. However, there is increasing evidence in the literature for secondary SUNCT being attributable to certain known lesions. We explored the possible neurobiological mechanism underlying SUNCT based on all reported cases of secondary SUNCT for which detailed information is available. Here we report a case of neuromyelitis optica spectrum disorders that had typical symptoms of SUNCT that might have been attributable to involvement of the spinal nucleus of the trigeminal nerve. We also review cases of secondary SUNCT reported in the English-language literature and analyze them for demographic characteristics, clinical features, response to treatment, and imaging findings. The literature review shows that secondary SUNCT can derive from a neoplasm, vascular disease, trauma, infection, inflammation, or congenital malformation. The pons with involvement of the trigeminal root entry zone was the most commonly affected region for inducing secondary SUNCT. In conclusion, the neurobiology of secondary SUNCT includes structures such as the nucleus and the trigeminal nerve with its branches, suggesting that some cases of primary SUNCT have underlying mechanisms that are related to existing focal damage that cannot be visualized.

Conclusions CEF in patients with drug-naive, first-episode schizophrenia is affected in a certain degree, especially the flexibility and attention transfer. Symptoms is the most serious influence factors. Treatment in sympotoms earlier is the important way to protect cool cognition.

Effect of Paidu Baoshen Pill on renal fibrosis in 5/6 nephrectomized rats / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the anti-renal fibrosis effect of Paidu Baoshen Pill (PBP) on 5/6 nephrectomized rats and to explore its mechanism.</p><p><b>METHODS</b>Totally 50 SD male healthy rats were randomly divided into the normal control group (n = 10), the sham-operation group (n = 10), and the nephrectomy model group (n = 30) according to the proportion of 1:1:3. Rats in the sham-operation group had their renal capsule isolated without nephrectomy. Rats in the nephrectomy model group had their kidneys 5/6 nephrectomized. Then 24 h urine was collected and 24 h urinary protein (24 h UP) detected. Serum blood urea nitrogen (BUN) and serum creatitine (SCr) were also tested. According to the SCr level 30 rats of the model group were further randomly divided into the model group, the PBP group, and the Niaoduqing Granule (NG) group, 10 in each group. Rats in the PBP group and the NG group were respectively administered with PBP (at the daily dose of 1.0 g/kg) and NG (at the daily dose of 3.33 g/kg) by gastrogavage (they were dissolved in distilled water). At the same time, 2 mL distilled water was administered by gastrogavage to rats in the normal control group, the sham-operation group, and the nephrectomy model group, once daily for 4 successive weeks. Mental conditions, activities, hair color, shape of stool, and the body weight were observed during administration. After 4 weeks, urine was collected to detect 24 h UP. Blood was sampled to detect SCr, BUN, transforming growth factor β1 (TGF-β1), type III procollagen (PC III), collagen type IV (Col IV), laminin (LN), and fibronectin (FN). After rats were killed, their left remnant renal tissues were collected for pathological examinations. The protein expression quantity of TGF-β1 and FN was detected by immunohistochemical method. mRNA expression levels of TGF-β1 and FN were detected using real time fluorescent quantitative PCR.</p><p><b>RESULTS</b>There was no statistical difference in the above indices between the normal control group and the sham-operation group (P > 0.05). Compared with the sham-operation group, rats' general condition was poorer in the model group, their body weight grew slower, and 24 h UP increased; serum levels of BUN, SCr, TGF-β1, PC III, Col IV, LN, and FN increased; the residual renal pathological lesion was serious; expression levels of TGF-β1, TGF-β1, mRNA, FN, and FN mRNA increased in the renal tissue (all P < 0.01). Compared with the model group, rats' general condition was better, their body weight grew faster, 24 h UP reduced (P < 0.05), blood levels of BUN and SCr decreased significantly (P < 0.01), serum levels of TGF-β1, PC III, CoL IV, LN, and FN decreased (P < 0.05, P < 0.01); the residual renal pathological lesion was attenuated in the PBP group and the NG group; expression levels of TGF-β1, TGF-β1, mRNA, FN, and FN mRNA decreased (P < 0.01).

Umbilical cord blood-derived mesenchymal stem cells ameliorate graft-versus-host disease following allogeneic hematopoietic stem cell transplantation through multiple immunoregulations / 华中科技大学学报（医学）（英德文版）

Although mesenchymal stem cells (MSCs) are increasingly used to treat graft-versus-host disease (GVHD), their immune regulatory mechanism in the process is elusive. The present study aimed to investigate the curative effect of third-party umbilical cord blood-derived human MSCs (UCB-hMSCs) on GVHD patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and their immune regulatory mechanism. Twenty-four refractory GVHD patients after allo-HSCT were treated with UCB-hMSCs. Immune cells including T lymphocyte subsets, NK cells, Treg cells and dendritic cells (DCs) and cytokines including interleukin-17 (IL-17) and tumor necrosis factor-alpha (TNF-α) were monitored before and after MSCs transfusion. The results showed that the symptoms of GVHD were alleviated significantly without increased relapse of primary disease and transplant-related complications after MSCs transfusion. The number of CD3(+), CD3(+)CD4(+) and CD3(+)CD8(+) cells decreased significantly, and that of NK cells remained unchanged, whereas the number of CD4(+) and CD8(+) Tregs increased and reached a peak at 4 weeks; the number of mature DCs, and the levels of TNF-α and IL-17 decreased and reached a trough at 2 weeks. It was concluded that MSCs ameliorate GVHD and spare GVL effect via immunoregulations.
