OBJECTIVETo evaluate the effect of electro-acupuncture (EA) on gastric mucosal oxygenation and systemic inflammatory response in patients undergoing endoscopic sinus surgery with controlled hypotension (CH), and to explore its protective effect on gastric mucosa.

METHODSFifty-four patients, 18-65 years old, grade I-II of American Society of Anesthesiology (ASA), who were scheduled for endoscopic sinus surgery were randomly assigned to two groups, group A (general anesthesia group) and group B (general anesthesia combined EA anesthesia group), 27 in each group. Conrolled hypotension was executed during operation, and mean arterial pressure (MAP) was maintained at 55-65 mmHg. After tracheal intubation gastric tesiometer catheter was indwelled through nasal cavity or oral cavity. After successful indwelling, it was connected with gastric mucosa monitoring mode of multifunctional parameters monitor. Patients' MAP and heart rate (HR), pHi, partial pressure of carbon dioxide (PgCO2), arterial partial pressure of carbon dioxide (Pg-aCO2) and endtidal pressure of carbon dioxide (Pg-etCO2) were measured and recorded at T, (immediately before induced hypotension), T, (20 min following induced hypotension to target MAP), T2 (40 min following induced hypotension to target MAP), T3 (20 min after ending induced hypotension), and T4(40 min after ending induced hypotension). Blood samples were intravenously collected, TNF-alpha, IL-1, and IL-6 were detected by ELISA 24 h before operation, during operation (T3), and 24 h after operation.

RESULTSAfter hypotension was induced, Pg-CO2, Pg-aCO2 and Pg-etCO2 increased significantly (P < 0.01, P < 0.05), while pHi decreased significantly (P < 0.01) in both groups at T1-T4 than those at T0. During T1-T4, PgCO2, Pg-aCO2, and Pg-etCO2 were higher (P < 0.01, P < 0.05), while pHi was lower in group A than in group B (P < 0.01). Furthermore, TNF-alpha, IL-1, and IL-6 increased significantly in both groups during operation and 24 h after operation, when compared with those 24 h before operation (P < 0.01, P < 0.05). TNF-alpha and IL-1 in group A were higher than those in group B (P < 0.05) during operation and 24 h after operation, but with no significant difference in the plasma concentration of IL-6 (P > 0.05).

CONCLUSIONEA exerted obvious protective effect of gastric mucosal injury in endoscopic sinus surgery with controlled hypotension, which might be achieved by increasing gastric mucosal blood flow, maintaining oxygen supply and demand, inhibiting inflammatory response, and alleviating injury of gastric mucosal barrier.

Abstract: Objective　To investigate the clinical and laboratory characteristics of pulmonary infection caused by Nocardia otitidiscaviarum. Methods　The clinical data of a patient with pulmonary infection caused by Nocardia otitidiscaviarum were reported, and the clinical characteristics, laboratory characteristics and drug sensitivity of pulmonary infection caused by Nocardia otitidiscaviarum were summarized in combination with the relevant literature at home and abroad from January 2010 to December 2022. Results　A 67-year-old female patient was admitted to the hospital on June 30, 2020 because of "repeated chest tightness and shortness of breath for 3 years, aggravated cough, expectoration and fever". The sputum, alveolar lavage fluid and blood of the patient were collected for culture, and the detected pathogenic bacteria were identified. There are pathogenic bacteria growing in sputum and alveolar lavage fluid, which are identified as Nocardia otitidiscaviarum by Autof ms mass spectrometer. According to the results of pathogenic bacteria and the patient's condition, meropenem combined with compound sulfamethoxazole tablets were given anti-infection treatment, and the patient's condition improved and discharged. Conclusion　The clinical manifestations and imaging features of nocardiosis are lack of specificity, and are prone to misdiagnosis and missed diagnosis. Etiology is the key to disease diagnosis, and clinical examination and culture should be conducted in time.

Objective To investigate the expression and clinical significance of peripheral blood CD4~+, CD25~+ and CD4~+CD25~+ T subpopulations in patients with systemic lupus erythematosis.Methods The per- centage and fluorescence intensities of peripheral blood CD4~+,CD25~+ and CD4~+CD25~+ subpopulations from 34 SLE and 18 normal controls were measured with flow cytometry assay,then the correlation with clincal data was analyzed.The CD25~+ cells were defined as the CD25~(high) cells if their fluorescence intensity was higher than 10. Results The percentage of CD4~+CD25~+,CD4~+CD25~(high) T lymphocytes in active SLE patients[(4.80?1.21)% and (0.25?0.10)%]was lower than that in normal controls[(8.92?3.21)% and(0.44?0.22)% and non-active SLE patients(11.28?2.09)% and(0.59?0.34)%](P＜0.05).However,as for the CD25~+ cells in the CD4~+ T cells,there was no difference between SLE patients and normal control group.Peripheral blood CD4~+CD25~+,CD4~+CD25~(high) cells in SLE were reversely correlated with SLEDAI(r=-0.74,P=0.004 and r=-0.614,P=0.026),but not with others such as complements,ANA titers etc.Peripheral blood CD4~+ and CD25~+ lymphocytes in active SLE pa- tients were also lower than those in normal controls[(23?7)vs(34?7)and(7.4?1.8)vs(13.9?3.4),P＜0.05]. CD25 fluorescence intensities were higher in the SLE patients those in the normal controls,but CD4 fluores- cence intensities were not.Conclusion CD4~+CD25~+ may play a role in the pathogenesis of SLE.

BACKGROUNDThe delivery of glucose from the blood to the brain involves its passage across the endothelial cells of the blood-brain barrier (BBB), which is mediated by the facilitative glucose transporter protein 1 (GLUT(1)), and then across the neural cell membranes, which is mediated by GLUT(3). This study aimed to evaluate the dynamic influence of hyperglycemia on the expression of these GLUTs by measuring their expression in the brain at different blood glucose levels in a rat model of diabetes. This might help to determine the proper blood glucose threshold level in the treatment of diabetic apoplexy.

METHODSDiabetes mellitus was induced with streptozotocin (STZ) in 30 rats. The rats were randomly divided into 3 groups: diabetic group without blood glucose control (group DM1), diabetic rats treated with low dose insulin (group DM2), and diabetic rats treated with high dose insulin (group DM3). The mRNA and protein levels of GLUT(1) and GLUT(3) were assayed by reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry, respectively.

RESULTSCompared with normal control rats, the GLUT(1) mRNA was reduced by 46.08%, 29.80%, 19.22% (P < 0.01) in DM1, DM2, and DM3 group, respectively; and the GLUT(3) mRNA was reduced by 75.00%, 46.75%, and 17.89% (P < 0.01) in DM1, DM2, and DM3 group, respectively. The abundance of GLUT(1) and GLUT(3) proteins had negative correlation with the blood glucose level (P < 0.01). The density of microvessels in the brain of diabetic rats did not change significantly compared with normal rats.

CONCLUSIONSChronic hyperglycemia downregulates GLUT(1) and GLUT(3) expression at both mRNA and protein levels in the rat brain, which is not due to the decrease of the density of microvessels. The downregulation of GLUT(1) and GLUT(3) expression might be the adaptive reaction of the body to prevent excessive glucose entering the cell that may lead to cell damage.
