Objective To investigate the effect and mechanism of ischemic postconditioning (IPC) on myocardial perfusion levels of acute ST-segment elevation myocardial infarction (STEMI) patients having underwent primary percutaneous coronary intervention (PCI), and the safety of IPC. Methods One hundred and sixty patients with STEMI were enrolled, and they accepted the primary PCI therapy within the onset of 12 h. The patients were divided into 2 groups according the treatment method:control group (routine PCI group, 82 cases) and IPC group (78 cases). The ST-segment resolution, TIMI myocardial perfusion grade (TMPG), before and after PCI levels of nitrogen monoxidum (NO), endothelin (ET)-1, tissue-type plasminogen activator (t-PA), plasminogen activator inhibitor (PAI)-1, rate of intraoperative complication were observed. The patients were followed up for 6 months, the rate of major adverse cardiac event (MACE) was recorded. Results The rates of ST-segment resolution and TMPG well in IPC group were significantly higher than those in control group:84.62%(66/78) vs. 67.07%(55/82) and 80.77%(63/78) vs. 64.63%(53/82), and the rate of ischemia-reperfusion injury in IPC group was significantly lower than that in control group: 7.69%(6/78) vs. 24.39%(20/82), and there were statistical differences ( P<0.05 or<0.01). The endothelial function and fibrinolysis activity indexes (NO, ET-1, t-PA and PAI-1 levels ) 7 d after PCI in IPC group were significantly better than those in control group: (52.37 ± 3.84) μmol/L vs. (50.95 ±3.85) μmol/L, (75.47 ±3.47) ng/L vs. (76.61 ±3.72) ng/L, (12.96 ±1.25) μg/L vs. (12.52 ±1.23) μg/L, (21.78 ±4.01)μg/L vs. (24.95±7.56)μg/L, and there were statistical differences (P<0.05 or<0.01). There was no statistical difference in the rate of intraoperative complication between 2 groups ( P>0.05). The rate of MACE in IPC group was significantly lower than that in control group:3.85% (3/78) vs. 14.63% (12/82), and there was statistical difference (P<0.05). Conclusions Applying IPC in patients with STEMI having underwent primary PCI is safe and can improve myocardial perfusion levels. The improvement of vessel endothelial function and fibrinolysis activity attained from IPC may be the major mechanism.

AIM To prepare the transdermal drug delivery system of carbon nanotubes graft ginsenosides Rb1 and Rb2 nanoemulsion.METHODS After 0.5％ carbon nanotubes' dispersion into the prepared nanoemulsion,the combination state was observed under transmission electron microscope.The skin irritation and transdermal mechanism of this drug delivery system were investigated.Then the UVA-damaged mouse skin model was established to evaluate the antioxidant activity.RESULTS Carbon nanotubes had strong adsorption to nanoemulsion,together with the formation of drug storage cavern in epidermis,thus increased the transdermal osmotic quantities of ginsenosides Rb1 and Rb2.The SOD activity in mouse skin tissue in the drug delivery system group was higher than that in the model group and the nanoemulsion group (P ＜0.01),and the MDA content was significantly decreased (P ＜ 0.01).CONCLUSION The transdermal drug delivery system of carbon nanotubes graft ginsenosides Rb1 and Rb2 nanoemulsion can make drugs play an antioxidant role because of its less irritation to skin and better skin permeability.

OBJECTIVE To study incidence of metallo-beta-lactamase(MBL)-producing Pseudomonas aeruginosa and their drug sensitivity.METHODS A total of 323 isolates of P.aeruginosa from Nanshan District of Shenzhen between Jun 2007 and Jun 2008 were subjected to susceptibility testing against various antibiotics and identified by ATB-Expression.Imipenem and meropenem resistant isolates were selected for the detection of MBL production by disc synergia test.Enhancement of inhibition zone around imipenem and meropenem discs impregnated with EDTA was found to confirme MBL production.RESULTS Totally 323 P.aeruginosa were isolated and MBL-producing accounted for 46(14.3%),drug resistance rate to imipenem and meropenem was respectively 45.4% and 26.3%.Colistin was the most sensitive to P.aeruginosa(96.9%).CONCLUSIONS Our findings show it needs to detect MBL producers,judiciously use carbapenems to prevent their spread.

Abstract: Objective　To analyze the epidemiological characteristics of 151 cases of melioidosis and the drug resistance of Burkholderia pseudomallei (BP), in order to provide the basis for diagnosis, treatment and reasonable prevention of melioidosis. Methods　A total of 151 inpatients and outpatients from the Second Affiliated Hospital of Hainan Medical University from January 1, 2013 to August 31, 2022 were collected, and clinical specimens were submitted for examination to isolate and identify BP strains. The clinical data of 151cases of melioidosis and the drug resistance characteristics of pathogenic bacteria were retrospectively analyzed, and using SPSS26.0 software for statistical analysis. Results　Among 151 cases with BP infection, there were 138 males (91.4%) and 13 females (8.6%); the most patients were aged from 45-<60 years old, accounting for 74 cases (49.0%); melioidosis incidence was concentrated in October (19.2%), November (19.2%), August (9.9%) and July (8.6%), and; the number of confirmed cases showed an increasing trend and the time for confirmation was <10 d; Internal medicine system (31.1%), surgery system (26.5%) and intensive care department (20.5%) were the common departments for treating melioidosis; blood (49.0%), sputum (9.9%) and wound secretion (8.6%) were the main clinical specimens for detecting BP; pulmonary infection (68.2%), sepsis (35.1%) and local suppurative infection (23.8%) were the top clinical manifestations in patients with BP infection; the effective rate of treating melioidosis was 74.8%; abnormal liver function was a risk factor for the curative effect of melioidosis (χ2=5.010, P<0.05); the sensitivity rates of BP strains to sulfamethoxazole-trimethoprim (SXT), doxycycline (DOX), imipenem(IPM), ceftazidime (CAZ), amoxicillin/clavulanate (AMC) and tetracycline (TCY) were generally more than 90%, with sensitivities of 98.7%, 97.2%, 96.7%, 94.0%, 93.2% and 90.7%, respectively. Conclusions　It can be concluded that misdiagnosis or missed diagnosis of melioidosis is easy to occur, and the understanding of the epidemiological characteristics and risk factors in this area should be strengthened. The sensitivity of BP to commonly used antibiotics has shown a certain downward trend, clinical use should be standardized, and drug resistance monitoring should be strengthened to improve the efficacy of melioidosis treatment.

Objective To correct the nasal deformities of cleft lip by expanded-polytetrafluoroe thylene (e-PTFE) combined with autologous nasal septal cartilage.Methods e-PTFE was placed nearby verge of anterior nasal aperture to raise the fundament of nose.Autologous nasal septal cartilage was harvested and combined with e-PTFE to form a sandwich structure.Nasal tip and collapsed nasaI alar were repaired by this method.Results Fifty cases were treated by this method and 42 cases were followed up for about one year.The results were satisfying.The contour of the nose was similar to normal.Only 3 cases were relapsed after one year.Conclusions e-PTFE combined with autologous nasal septal cartilage is an ideal method to correct nasal deformities of cleft lip.

Objective This study aimed to establish the leukemia mouse model by using EL4/DsRed cell line expressing red fluorescent protein (DsRed) and to evaluate the model. Methods After total body irradiation with X-ray of 7.0 Gy, C57BL/6 mice were inoculated 5×106 bone marrow cells mixed different numbers of EL4/DsRed cells via tail vein. The model was evaluated by flow cytometry (FCM), reverse transcriptase-polymerase chain reaction (RT-PCR), and histopathology. Results The incidence of leukemia was 100 %. The presence of EL4/DsRed cells was found in liver, spleen, bone marrow and peripheral blood of recipients by FCM two weeks after transplantation. Pathological section revealed that all recipients had several organs infiltration apparently. With the increase in the number of inoculated tumor cells, the survival time of recipients was reduced and the infiltration of leukemia cells in organs was more serious. Conclusion Mouse leukemia model was successfully established when C57BL/6 mouse was intravenously transplanted with ≥5×102 EL4/DsRed cells. The model could be employed usefully in the future research such as the pathogenesis of leukemia and minimal residual disease (MRD).
