Among inorganic salts tested, K 2HPO 4 was more essential to the sclerotia for mation and carotenogenesis of strain PT95 than KCl, MgSO 4 or FeSO 4 It wa s also shown that the combination of K 2HPO 4, KCl and MgSO 4 could produce t he best positive cooperation and give the highest sclerotia biomass (782mg/plate ) and pigment yield (328 ?g/plate) Five carbon sources, i e glucose sucros e, lactose, maltose and soluble starch, all could be utilized by the strain PT95 , and maltose was the best Among 8 nitrogen sources, yeast extract favooured t he sclerotia formation, and peptone fovoured the pigment accumulation; amine sal ts and urea were unfavourable to form sclerotia The medium containing 0 24 ～ 0 48 g/L sodium nitrate nitrogen was effective to both the sclerotia formation and the carotenoid production of strain PT95 when available maltose carbon con centrations were at 5 26～21 05 g/L The optimal C/N ratio was found to be 25 ∶1

Objective:To investigate the value of combined detection of biomarkers in early diagnosis and prognosis of patients with septic myocardial injury.Methods:The clinical data of 103 patients with sepsis admitted to the intensive care unit (ICU) of the First Affiliated Hospital of Baotou Medical College of Inner Mongolia University of Science and Technology from October 2018 to January 2021 were enrolled. According to the cardiac troponin I (cTnI) at admission of ICU, they were divided into septic myocardial injury group (cTnI ≥ 0.15 μg/L) and non-septic myocardial injury group (cTnI < 0.15 μg/L). The serum levels of heart-type fatty acid-binding protein (H-FABP), procalcitonin (PCT), C-reactive protein (CRP), MB isoenzyme of creatine kinase (CK-MB), cTnI and N-terminal pro-brain natriuretic peptide (NT-proBNP) within 6 hours after ICU admission and the worst value of acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score within 24 hours after ICU admission in 103 patients was recorded as well as the 28-day prognosis of patient with septic myocardial injury. Spearman correlation analysis was used to analyze the correlation of each index; receiver operating characteristic curve (ROC curve) was drawn, and the area under ROC curve (AUC) was calculated to analyze the early diagnosis and prognostic value of each index and APACHEⅡ score alone or combined detection in patients with septic myocardial injury.Results:① Among 103 patients with sepsis, 58 patients were complicated with myocardial injury and 45 patients were not complicated with myocardial injury. The serum levels of PCT, CRP, NT-proBNP, CK-MB, cTnI, H-FABP and APACHEⅡ score in patients with septic myocardial injury were significantly higher than those in patients without septic myocardial injury [PCT (μg/L): 3.46±1.35 vs. 1.89±0.43, CRP (mg/L): 81.1±26.8 vs. 65.3±19.1, NT-proBNP (U/L): 8 261.4±2 346.9 vs. 6 120.2±1 809.6, CK-MB (U/L): 15.89±6.25 vs. 12.14±4.24, cTnI (μg/L): 1.50 (0.91, 2.21) vs. 0.18 (0.16, 0.19), H-FABP (μg/L): 26.45±8.24 vs. 12.82±5.73, APACHEⅡ score: 24.0 (18.0, 29.0) vs. 16.0 (14.0, 18.0), all P < 0.01]. Spearman correlation analysis showed that PCT, CRP and APACHEⅡ scores were positively correlated with NT-proBNP, CK-MB, cTnI and H-FABP. ROC curve analysis showed that H-FABP in the diagnosis of septic myocardial injury (AUC = 0.916) was superior to NT-proBNP (AUC = 0.756) and CK-MB (AUC = 0.675); the AUC of NT-proBNP and CK-MB combined with H-FABP was 0.921, the sensitivity was 82.1%, and the specificity was 88.2%.② Twenty-three patients survived in 28 days, and 35 died. The levels of serum PCT, CRP, NT-proBNP, CK-MB, cTnI, H-FABP and APACHEⅡ score in death group were significantly higher than those in survival group [PCT (μg/L): 3.86±1.27 vs. 2.84±1.24, CRP (mg/L): 92.3 (65.0, 101.7) vs. 74.3 (65.7, 79.8), NT-proBNP (ng/L): 9 106.4±2 013.9 vs. 6 975.5±2 266.7, CK-MB (U/L): 17.90±6.49 vs. 12.82±4.46, cTnI (μg/L): 2.11±0.86 vs. 1.12±0.44, H-FABP (μg/L): 30.08±7.90 vs. 20.93±5.14, APACHEⅡ score: 25.0 (20.0, 30.0) vs. 19.0 (17.0, 24.0), all P < 0.01]. ROC curve analysis showed that H-FABP in evaluating 28-day death of patients with septic myocardial injury (AUC = 0.839) was superior to PCT (AUC = 0.707), CRP (AUC = 0.716), NT-proBNP (AUC = 0.761), CK-MB (AUC = 0.733), cTnI (AUC = 0.824) and APACHEⅡ score (AUC = 0.724); the AUC of NT-proBNP and cTnI combined with H-FABP was 0.888, the sensitivity was 91.4%, and the specificity was 82.6%. Conclusions:H-FABP plays an important role in the early diagnosis and prognosis of septic myocardial injury. Early combined detection of NT-proBNP, CK-MB and H-FABP can significantly improve the diagnostic ability of septic myocardial injury, and NT-proBNP and cTnI combined with H-FABP can significantly improve the ability to predict the adverse prognosis of sepsis myocardial injury.

Objective To study the clinical features and treatment of cervical spondylosis with dissociated motor loss in upper extremity. Methods Data analysis was done in 10 patients with cervical spondylosis with dissociated motor loss in upper extremity, in aspects of symptoms, sign, radiologic feature, electromyogram and treatment. Results There are 2 subtypes of cervical spondylosis with dissociated motor loss in upper extremity: Keegan and Non-Keegan types. The patients with Keegan type of cervical spondylosis manifested weakness and atrophy in the upper extremity, and no radicular pain was reported. The Non-Keegan type is in fact a combination of radicular and spinal insult in the cervical region. Our clinical practice showed that surgical operation was preferred to the conservative treatment for patients with this disease. Conclusion A well understanding of this disease is of great importance for avoiding mistakes in diagnosis and treatment of this disease.

Objective To investigate the synergetic effect of combined astaxanthin ( AST) and lith-ium chloride ( LiCl) treatment on cognitive dysfunction of chronic omethoate poisoned mice. Methods 8 mice were selected randomly as control group from 55 healthy adult male Kunming mice,and the rest were used to establish chronic organophosphate poisoning cognitive impairment models by injecting omethoate 5 mg/kg subcutaneously every day for 4 weeks. Totally 40 successfully established models were randomly divid-ed into model group,AST group,edaravone group,LiCl group and AST+LiCl group with 8 in each. Morris wa-ter maze test was used to examine the learning and memory ability of mice. Contents of reactive oxygen spe-cies (ROS) in hippocampus were measured by enzyme-linked immunosorbent assay (ELISA). Activity of superoxide dismutase ( SOD) in hippocampus was measured by colorimetric assay. Morphology of hippocam-pus area was observed by HE staining. The distribution and expression of p-PI3K,p-Akt,p-GSK3β and p-CREB were determined by immunohistochemical staining ( IHC staining) and Western blot. Results The average escape latency of 5 days in each group was statistically significant (F=1662.147, P<0.05) . The av-erage escape latency of 5 days in AST+LiCl group was significantly lower than that in model group ( all P<0.05) and was lower than other treatment groups. Compared with the control group (0.087±0.007,0.084± 0.009,0.097±0.002,0.076±0.012),the hippocampal neuronal injury in model group was serious,the expres-sions of p-PI3K (0.032±0.008),p-Akt (0.03±0.006),p-GSK3β (0.028±0.007) and p-CREB (0.020± 0.008) was significantly lower ( all P<0.05) . The injuries of hippocampal neurons in AST+LiCl group were slightly lighter than that in model group,and the expression of p-PI3K (0.067±0.008),p-Akt (0.065± 0.005),p-GSK3β (0.068±0.009) and p-CREB (0.062±0.008) in hippocampus was significantly higher than that in model group ( all P<0.05) . Conclusion Combined AST and LiCL treatment exerts neuroprotec-tive effect on cognitive dysfunction induced by chronic organophosphate poisoning via up-regulating the ex-pression of Akt/GSK3β/CREB.
