RESUMEN
OBJECTIVE To investigate the effects of Setaria italica extract on improving insomnia model mice and to explore its potential mechanisms. METHODS The mice were randomly assigned into blank group， model group， positive control group （diazepam， 2.6 mg/kg）， and S. italica extract low-dose， medium-dose and high-dose groups （1.2， 2.4， 4.8 g/kg）， with 10 mice in each group. Except for the blank group， all other groups received intraperitoneal injection of para-chlorophenylalanine （PCPA） to establish the insomnia model. After modeling， the blank group and model group were given a constant volume of normal saline intragastrically， and administration groups were given relevant medicine intragastrically， with a volume of 0.01 mL/g， once a day， for 7 consecutive days. After the administration， the open-field test was conducted to observe the praxiological changes of mice， and to determine the levels of 5-hydroxytryptamine （5-HT） and 5-hydroxyindoleacetic acid （5-HTAA） in the hippocampal tissue， as well as the contents of 5-HT， brain-derived neurotrophic factor （BDNF）， interleukin-2 （IL-2）， IL-6， B-cell lymphoma-2 （Bcl- 2）， and Bcl-2-associated X protein （Bax） in the serum. The expression of phosphoinositide 3-kinase/protein kinase B/nuclear factor- κB （PI3K/Akt/NF-κB） signaling pathway related protein was determined in the hippocampus of mice. RESULTS Compared with the model group， the total exercise time of mice in S. italica extract high-dose group was significantly prolonged， but the total rest time was significantly shortened （P＜0.01）； the number of standing times and modification times were significantly reduced （P＜ 0.01）. The contents of 5-HT， BDNF， and Bcl-2 in serum， and Bcl-2/Bax were significantly increased， while the contents of IL-2， IL-6， and Bax were significantly reduced （P＜0.05 or P＜ 0.01）. The content of 5-HTAA in the hippocampal tissue and 202104010910029）；the phosphorylation levels of PI3K and Akt proteins were increased significantly， while the phosphorylation level of NF-κB p65 protein was decreased significantly （P＜0.05）.CONCLUSIONS High-dose of S. italica extract demonstrates significant therapeutic effects on insomnia in mice， and the mechanism of which may be associated with the regulation of PI3K/Akt/NF-κB signaling pathway.
RESUMEN
Objective: To summarize the clinical and genetic characteristics of children with β-ketothiolase deficiency (BKTD). Methods: The clinical characteristics, biochemical, markers detected by tandem mass spectrometry (MS/MS) and gas chromatography-mass spectrometry (GC/MS), as well as the variants in ACAT1 gene among 5 children with BKTD in Children's Hospital of Chongqing Medical University between October 2018 and December 2022 were retrospectively analyzed. Results: The onset age of the disease in 5 patients (4 males and 1 female) ranged from 9.7 to 28.0 months. During the acute phase, severe metabolic acidosis was observed with a pH of 6.9-7.1, as well as hypoglycaemia (2.3-3.4 mmol/L) and positive urinary ketone bodies (+-++++). Blood levels of methylcrotonyl carnitine, methylmalonyl carnitine and malonyl carnitine were 0.03-0.42, 0.34-1.43 and 0.83-3.53 μmol/L respectively and were significantly elevated. Urinary 2-methyl-3-hydroxybutyric acid was 22-202 and 3-hydroxybutyric acid was 4-6 066, both were higher than the normal levels. Methylcrotonylglycine was mild elevated (0-29). The metabolites detected by MS/MS and GC/MS were significantly reduced after treatment. Analysis of ACAT1 gene mutation was performed in 5 children. Most variants were missense (8/9). Four previously unreported variants were identified: c.678G>T (p.Trp226Cys), c.302A>G (p.Gln101Arg), c.627_629dupTGA (p.Asn209_Glu210insAsp) and c.316C>T (p.Gln106Ter), the first 2 variants were predicted to be damaging by SIFT, PolyPhen-2 and Mutation Taster software. c.316C>T (p.Gln106Ter) is a nonsense variant. Conclusions: β-ketothiolase deficiency is relatively rare, lacks specific clinical manifestations, however severe metabolic acidosis, hypoglycemia, and ketosis during the acute onset were consistent findings. Missense mutations in the ACAT1 gene are common genetic causes of β-ketothiolase deficiency.

Objective:To summarize the clinical characteristics of patients with Guillain-Barré syndrome (GBS) complicated with optic neuritis (ON).Methods:The clinical data of a patient with GBS complicated with ON, who admitted to the Department of Neurology, the First Hospital of Shanxi Medical University in December 2021, were collected, including demographic characteristics, clinical symptoms and signs, laboratory and electrophysiological data, and results of fundus color films. The patients with GBS complicated with ON reported in the literature were also reviewed.Results:A 40-year-old female patient with GBS was diagnosed by the results of electromyography and cerebrospinal fluid tests combining with the history and signs, who was treated with intravenous immunoglobulin on the 3rd day after onset. On the 8th day, her muscle strength improved significantly. However, on the 12th day, the visual field darkened, and on the 19th day, the vision decreased significantly (oculus dexter visual acuity 0.2, oculus sinister visual acuity 0.1 +1) with bilateral papilloedema, a relative afferent pupillary defect and delayed P100 response of the visual evoked potential. Obvious abnormality was not noted in optic nerve magnetic resonance imaging. Thus ON was diagnosed and treated with pulse methylprednisolone therapy. After 8 days of treatment, the visual acuity was completely recovered and there was no abnormality in the ocular fundus. A total of 28 cases of GBS complicated with ON (including the present patient) were reported in the literature. The age of onset was mostly 20-60 years, and there was no gender preference. Mycoplasma pneumoniae was the most common premorbid pathogen and was identified in 7 of the 10 cases in which the causative agent was described. ON usually involved both sides, and 21 of 28 patients had bilateral optic nerves involved. GBS preceded ON or both occurred simultaneously in the majority of patients; GBS preceded ON in 14 of 28 patients, and both occurred simultaneously in 10 of 28 patients. All patients responded well to immunotherapy, and vision was completely recovered in 20 patients. Conclusions:GBS complicated with ON is rare. Attention should be paid to the loss of vision in patients with GBS. Relevant examinations should be completed as soon as possible and immunotherapy should be given.
RESUMEN
Objective:To describe the clinical features of a patient of anti-neurofascin 186 (NF186) antibody associated acute immune sensory polyradiculopathy (AISP), and enhance understanding of AISP/chronic immune sensory polyradiculopathy (CISP).Methods:The clinical characteristics, diagnosis and treatment of a domestic AISP patient with NF186 antibody positive admitted to the First Hospital of Shanxi Medical University in December 2021 were summarized, and the previously reported cases of AISP/CISP were systematically reviewed.Results:The patient was a 62-year-old male with acute onset. The clinical manifestations included severe sensory ataxia, increased protein in cerebrospinal fluid, no response to stimulation of the central segment of somatosensory evoked potentials (SEP), normal sensory and motor nerve conduction, and positive serum anti-NF186 antibody (1∶32). After glucocorticoid treatment, the clinical symptoms and SEP were significantly improved. The drug was stopped for 2 months, and there was no recurrence. There were 23 cases of AISP and CISP with complete data reported in the literature (including this patient). The age of onset was (54.7±17.7) years, and the ratio of male to female was 1.88. Three patients with acute onset were classified as AISP. A total of 95.7% (22/23) of patients showed sensory ataxia without limb weakness, 95.0% (19/20) of patients showed prolonged cortical potential latency or even no response, and 95.5% (21/22) of patients showed increased cerebrospinal fluid protein in varying degrees, and nerve root thickening or abnormal enhancement was not common. All 10 patients receiving immunotherapy responded to corticosteroids or intravenous immune globulin. Only 6 AISP/CISP articles reported screening for anti-ganglioside antibodies or Ranvier′s node-paranodal region-related antibodies, and no positive NF186 antibodies were reported. All the 3 patients with AISP had some characteristics of CISP/chronic inflammatory demyelinating polyradiculoneuropathy, and there was no significant difference between AISP and CISP patients in clinical features except the mode of onset.Conclusions:NF186 antibody could cause AISP, which presents as acute onset sensory ataxia. AISP is responsive to glucocorticoid therapy. Except for the mode of onset, AISP and CISP are difficult to distinguish from clinical, electrophysiological, pathological aspects and pathogenic antibodies, so they may be two different manifestations of the same disease.
RESUMEN
Objective:To investigate the clinical efficacy and prognostic factors of 125I seeds implantation in the treatment of patients with advanced lung cancer after radiotherapy and chemotherapy. Methods:From January 2017 to December 2019, 44 patients (39 males, 5 females, age 41-84 years) with advanced lung cancer after radiotherapy and chemotherapy who received 125I seeds implantation in Hebei General Hospital were retrospectively analyzed. All patients were followed up for ≥12 months, and the clinical efficacies were observed. χ2 test was used to analyze the difference of effective rates between groups. The cut-off value of postoperative dose delivered to 90% gross tumor volume ( D90) was obtained by ROC curve analysis. Kaplan-Meier method was used to calculate the survival rate and log-rank test was used for univariate analysis. Cox proportional hazards model was used for multivariate analysis to find the influencing factors for clinical efficacy. Results:The total effective rate was 72.73%(32/44) after 6 months treatment. The cut-off value of D90 was 120 Gy with the AUC of 0.771. The short-term effective rate of D90≥120 Gy group was better than that of D90<120 Gy group (18/19 vs 56.00%(14/25); χ2=8.17, P=0.004). The 1-year survival rate was 77.27%(34/44). Univariate analysis showed that age ( χ2=3.99, P=0.046), preoperative Hb ( χ2=10.60, P=0.001), tumor maximum diameter ( χ2=11.50, P=0.001) and postoperative D90( χ2=5.81, P=0.016) could affect the survival of patients. Multivariate analysis showed that preoperative Hb (hazard ratio ( HR)=0.023, 95% CI: 0.001-0.882, P=0.043) and tumor maximum diameter ( HR=40.889, 95% CI: 1.458-1 146.586, P=0.029) were prognostic factors. Conclusions:125I seeds implantation shows a good effect in the treatment of lung cancer patients after the progress of radiotherapy and chemotherapy. The short-term effect of patients with D90≥120 Gy is better than that of patients with D90<120 Gy. Preoperative Hb and tumor maximum diameter are prognostic factors of survival after implantation.
RESUMEN
Objective:To investigate the prevention and risk factors of deep vein thrombosis (DVT) in the lower extremity after medial open wedge high tibial osteotomy (HTO).Methods:A total of 128 patients who underwent medial open wedge HTO in the Third Hospital of Hebei Medical University from January 2020 to October 2022 were retrospectively analyzed, including 45 males and 83 females, aged 59.3±6.8 years (range, 44-87 years). Postoperative anticoagulation with enoxaparin sodium was applied at a randomized dose of 4,000 AXaIU/d or 6,000 AXaIU/d. Gender, age, history of chronic diseases (hypertension, diabetes), smoking history, body mass index, and body fat percentage were collected. On admission, the risk of DVT was assessed using the Caprini scale and calf circumference was measured. Hemoglobin, D-dimer, antithrombin III, activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB), fibrinogen degradation products (FDP), glutathione, glutathione, urea, creatinine, uric acid were recorded. Patients were divided into DVT group and non-DVT group according to whether DVT occurred after operation. Binary logistic regression was used to analyze the independent risk factors of DVT after HTO. The receiver operating characteristic (ROC) curve was plotted, and the area under curve (AUC) was calculated to analyze the predictive value of the postoperative Caprini scale in the occurrence of DVT after HTO.Results:A total of 128 patients were enrolled, 83 patients were treated with enoxaparin sodium 4 000 AXaIU/d and 45 patients were treated with enoxaparin sodium 6 000 AXaIU/d. According to the results of color Doppler examination of bilateral lower extremity veins on the third day after operation, DVT occurred in 39% (50/128) of patients, including 39 cases of calf intermuscular thrombosis, 6 cases of peroneal vein thrombosis, 4 cases of posterior tibial vein thrombosis, and 1 case of popliteal vein thrombosis. DVT occurred in 36% (30/83) of patients receiving 4 000 AXaIU/d enoxaparin sodium and 44% (20/45) of patients receiving 6 000 AXaIU/d enoxaparin sodium, with no statistically significant difference (χ 2=0.84, P=0.358). Univariate analysis showed that smoking history, postoperative Caprini scale≥8, and female may be associated with the development of DVT after HTO ( P<0.05). They were included in the binary logistic regression, and the results showed that postoperative Caprini scale≥8 was an independent risk factor for DVT after HTO. The ROC curve of postoperative Caprini scale for predicting DVT after HTO was drawn, and the AUC was 0.847 (95% CI: 0.73, 0.96), the optimal cut-off value was 8, and the sensitivity and specificity were 84.2% and 77.6%, respectively. Conclusion:Caprini scale≥8 is an independent risk factor for DVT after medial open wedge HTO. Caprini scale has a good value in predicting the occurrence of DVT after HTO. The recommended dose of enoxaparin sodium is 4 000 AXaIU/d for the prevention of postoperative DVT, and increasing the dose is not associated with a decreased risk of DVT.
RESUMEN
During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Objective:To analyze the mechanism of Jindan Tablets, Xiaoyan Lidan Tablets and ursodeoxycholic acid in the treatment of gallstone and cholecystitis based on network pharmacology; To conduct a comparative analysis.Methods:The chemical components of Jindan Tablets, Xiaoyan Lidan Tablets and ursodeoxycholic acid and their drug targets were collected from Traditional Chinese Medicine Database and Analysis Platform (TCMSP). DAVID 6.8 database was used to search for the associated diseases of the drug targets. The disease targets of gallstone and cholecystitis were collected from GeneCards and other databases. The protein-protein interactions network was established based on the intersecting targets of three drugs and two diseases. KEGG enrichment analysis was performed based on the DAVID 6.8 database. Cytoscape 3.7.1 software was used to construct a complex network and topology analysis of component- target- disease between three drugs and diseases.Results:222 chemical components and 3 133 drug targets were collected for Jindan Tablets. 104 chemical components and 1 425 action targets were collected for Xiaoyan Lidan Tablets. 1 chemical component and 119 action targets were collected for ursodeoxycholic acid. The three drugs were associated with 31 diseases. 1 382 disease targets for gallstones and cholecystitis were collected. There were 237, 163 and 33 targets for gallstones and cholecystitis in the three drugs, of which 17 were shared by the three drugs and 20 were shared by Jindan Tablets and Xiaoyan Lidan Tablets. Based on the DAVID database, 113, 74 and 10 significant KEGG enrichment pathways were obtained for the three drugs respectively.Conclusions:The three drugs shared many targets and pathways in the treatment of gallstones and cholecystitis, which all had the function of regulating metabolism and inhibiting inflammatory response, while participating in apoptosis, oxidative stress and cancer pathology process. However, they had their own special effects, with Jindan Tablets favoring involving in the cancer process and inhibition of inflammation, and promoting angiogenesis. Xiaoyan Lidan Tablets and ursodeoxycholic acid focused on regulating cholesterol metabolism, and Xiaoyan Lidan Tablets also regulated steroid metabolism and inhibit inflammation, while ursodeoxycholic acid regulated bile acid metabolism.
RESUMEN
Objective:To study the clinical value of SRY-Box transcription factor 7 ( SOX7) gene methylation in renal cancer and its effect on the biological behavior of renal cancer cells. Methods:80 patients with renal cancer (the kidney cancer group) and 50 patients with benign renal disease (the control group) were selected as the research subjects. Synthetic oligonucleotide sequences (MON, UMON, and CON) were designed and transfected into A498 renal carcinoma cells. Methyl-specific PCR was used to detect the methylation status of the SOX7 gene in the tumor and adjacent tissue of the kidney cancer group as well as in the renal tissue of the control group. The relationship between SOX7 gene methylation and clinicopathological factors was analyzed. The migration and invasion of A498 renal cancer cells in the MON group, UMON group, and CON group were detected by the Transwell chamber. Results:The SOX7 gene methylation rate in tumor tissue of the kidney cancer group was significantly higher than that of the control group and the adjacent tissue, and the difference was statistically significant (χ 2 = 67.522, P < 0.05). The SOX7 gene is methylated in renal cancer cell lines such as Caki-1, 786-O, 769-P, while it is unmethylated in A498 renal cancer cells. There were no statistical differences in the SOX7 gene methylation rate in the tumor tissue of the renal cancer group in terms of gender, age, or pathological type (all P > 0.05). There were statistical differences in the degree of differentiation, maximum tumor diameter, lymph node metastasis, tumor number, and TNM staging in the renal cancer group in terms of tumor tissue SOX7 gene methylation rate (all P < 0.05). After transfection with MON, the SOX7 gene methylation of A498 renal cancer cells could be successfully induced, and the day-1 to day-7 cell viability, cell migration, and invasion numbers of A498 renal cancer cells in the MON group were significantly higher than those in the UMON group and the CON group ( P < 0.05). Conclusions:Hypermethylation of the SOX7 gene can promote the proliferation, migration, and invasion of renal cancer cells and has important clinical value in the evaluation of the disease and prognosis of renal cancer.

Xanthocillin is a unique natural product with an isonitrile group and shows remarkable antibacterial activity. In this study, the genome of an endophytic fungus Penicillium chrysogenum MT-40 isolated from Huperzia serrata was sequenced, and the gene clusters with the potential to synthesize xanthocillin analogues were mined by local BLAST and various bioinformatics analysis tools. As a result, a biosynthetic gene cluster (named for) responsible for the biosynthesis of xanthocillin analogues was identified by further heterologous expression of the key genes in Aspergillus oryzae NSAR1. Specifically, the ForB catalyzes the synthesis of 2-formamido-3-(4-hydroxyphenyl) acrylic acid, and the ForG catalyzes the dimerization of 2-formamido-3-(4-hydroxyphenyl) acrylic acid to produce the xanthocillin analogue N, N'-(1, 4-bis (4-hydroxyphenyl) buta-1, 3-diene-2, 3-diyl) diformamide. The results reported here provide a reference for further discovery of xanthocillin analogues from fungi.

Brasilicardin A (BraA) is a natural diterpene glycoside isolated from the pathogenic actinomycete Nocardia brasiliensis IFM 0406 with highly potent immunosuppressive activity (IC50=0.057 μg/mL). BraA potently inhibits the uptake of amino acids that are substrates for amino acid transport system L of T cells, which is different from the existing clinical immunosuppressants. BraA is more potent in a mouse mixed lymphocyte reaction and less toxic against various human cell lines compared with the known clinical immunosuppressants, such as cyclosporin A, ascomycin and tacrolimus. Therefore, BraA attracted more attention as a new promising immunosuppressant. However, the development of this promising immunosuppressant as drug for medical use is so far hindered because BraA has the unusual and synthetically challenging skeleton and shows the low-yield production in the natural pathogenic producer. This review introduces the molecular structure of BraA, its activity, mechanism of action, chemical synthesis of BraA analogs, heterologous expression of gene cluster, and an application of combining microbial and chemical synthesis for production of BraA, with the aim to facilitate the efficient production of BraA and its analogs.

Objective To study the effect of dexmedetomidine (DEX), an α2- adrenoceptor agonist, on the pain-related anxiety-like and depression-like behaviour induced by complete Freund' s adjuvant (CFA) injection and its possible regulatory mechanism. Methods Thirty-six ICR female mice were randomly divided into normal saline (NS) group, CFA group and DEX + CFA group, n = 12 for each group. Chronic inflammatory pain model was established by subcutaneous injection of 10 μl CFA into the right hind limb of mice. DEX + CFA group mice were injected intraperitoneally with 0.025 mg/kg DEX 30 minutes before nociceptive behavior test, and once a day for 7 days. Von-frey fiber was used to evaluate the threshold of mechanical pain in mice, n = 12 for each group. The anxiety-like behavior of mice were detected by open field test, n = 12 for each group. Sucrose preference, tail suspension test and forced swimming test were used to detected the depression-like behavior of mice, n = 12 for each group. The expression of adrenergic receptor β2 (ADRB2), Brain-derived neurotrophic factor (BDNF), tyrosine kinase B receptor (TrkB), and glutamate receptors 1 (GluR1) and GluR2 were detected by Western blotting, n = 8 for each group. Immunohistochemical staining was used to detect the expression of recombinant doublecortin(DCX), which is a marker of newborn neurons in the hippocampus, n = 4 for each group. Results Compared with the NS group, the mechanical threshold of mice on the 1st, 3rd and 7th day after CFA injection decreased significantly (P 0.05). Compared with the NS group, the time spent in the inner ares (P<0.01), number of entering the central grid area (P<0.01) and distance travelled in the inner area (P<0.01) of CFA group mice reduced significantly, while the time (P<0.01), numbers (P < 0.05) and distance (P < 0.05) of DEX + CFA group mice entering the central grid area enhanced significantly. The result of depression-like behavior tests showed that the sucrose preference percentage (P < 0.05) reduced significantly in CFA group when compared with NS group, and the immobility time increased significantly in tail suspension test (P<0.01) and forced swimming test (P< 0.001) in CFA mice when compared with NS group, while DEX intervention could significantly increase the sucrose preference scores (P<0.05) and decreased the immobility time in tail suspension test (P<0.05) and forced swimming test (P<0.05). The result of Western blotting showed that compared with the NS group, the levels of ADRB2 (P<0.0010), BDNF (P < 0.001), TrkB (P < 0.01), GluR1 (P < 0.001) and GluR2 (P < 0.001) in the hippocampus of CFA group were significantly decreased, while DEX intervention could significantly increase the expression of ADRB2 (P<0.05), BDNF (P < 0.001), TrkB (P < 0.001), GluR1 (P < 0.001) and GluR2 (P < 0.001). Immunohistochemical result showed that compared with the NS group, the average absorbance (AA) of DCX decreased significantly in hippocampus of CFA group (P<0.05), but increased significantly in DEX+CFA group (P < 0.05). Conclusion Dexmedetomidine may promote hippocampal neurogenesis through upregulated the expression of BDNF-TrkB, thus improving CFA-induced anxiety-like and depression-like behaviors in mice.
RESUMEN
[Abstract] Objective To elucidate the important role of Nogo-A in climacteric neurodegeneration such as memory impairment by observing memory function and the expression of Nogo-A in hippocampus and striatum of rats under low estrogen condition. Methods Fouthy-five female SD rats were divided into sham operation group, ovariectomized group and ovariectomized estrogen treatment group with 15 rats in each group. Medication was given 2 weeks after ovariectomized. Estrogen treatment group was subcutaneously injected in groin with estrogen [25 μg/ (kg.d)] dissolved in sterile sesame oil. The sham operation group and the ovariectomized group were given the same amount of aseptic sesame oil. Samples were collected after 6 weeks of drug treatment. The difference of memory function of rats in three groups was observed by conditioned fear training experiment, and the expression of Nogo-A in hippocampus and striatum was observed by immunohistochemistry and Western blotting. Results Compared with the sham and estrogen treatment group, memory function in ovariectomized group decreased significantly and the number of Nogo-A positive neurons in hippocampus and striatum of ovariectomized rats was significantly higher than that of sham operation group (P 0. 05). The result of immunoblotting was consistent with the above-mentioned immunohistochemical result. Conclusion The increased expression of Nogo-A in hippocampus and striatum under low estrogen condition may be one of the key reasons for memory impairment in climacteric women.
