Moyamoya disease is a chronic progressive cerebrovascular disease. It got its nickname, the moyamoya disease, because the image of abnormal blood vascular net at the skull base in the encephaloangiography of such patients is very similar to smog. The moyamoya disease can be divided into two types: ischemic and hemorrhagic according to its clinical manifestations and imaging characteristics. In the ischemic type of moyamoya disease, when the blood vascular lumens are not narrow enough to completely block the blood flow, the chief manifestation is the cerebral blood circulation insufficiency; when the salvage is not in time, the disease will further progress to develop vascular obstruction or thrombosis, resulting in cerebral infarction, finally hemiplegia, aphasia, etc. irreversible symptoms and signs occur. In the primary hospital, the first choice for treatment of acute cerebral infarction (ACI) is drug thrombolysis. However, the main treatment for moyamoya disease with ACI is chiefly revascularization. This article reported a patient with moyamoya disease and ACI successfully treated by intravenous reteplase for thrombolysis in People's Hospital of Pucheng County.

OBJECTIVE To investigate the resistance of Acinetobacter baumannii(ABA),and the mechanism of imipenem resistance in A.baumannii.METHODS All specimens were identified by VITEK-60 and the drug resistance was detected by Kirby-Bauer test.Three dimensional test was used to detect ESBLs and AmpC.PCR and DNA sequencing were performed to determine VIM,IMP,OXA-23 and OXA-24 ?-lactamases.Outer membrane protein was analyzed by SDS-PAGE,Reserpine synergistic inhibition test was used to study the active efflux mechanism.RESULTS Totally 120 strains were isolated from sputum(76.9%),and 16 strains from secretion(10.3%).ICU was the main infected department(51 strains,32.7%).The resistance to sulperazone was the lowest(20.5%),and to imipenem accounted for 38.5%,Of the 20 imipenem resistant strains,10 strains were ESBLs positive(50%),and 20 strains were AmpC positive(100%).VIM,IMP and OXA-24 ?-lactamases were not detected out,19 strains(95%) produced OXA-23.Compared to the imipenem-sensitive strains,the resistant strains lacked the outer membrane protein of 22?103,29?103 and 33?103.The MICs of A.baumannii to imipenem were not decreased by reserpine which demonstrated that excretive mechanism was negative.CONCLUSIONS ICU is the main infected department for ABA.The resistance rate is increasing for longer-term usage of carbopenem;OXA-23 production is the important resistance mechanism in ABA,AmpC production and outer membrane protein lacking show close relation to the drug-resistance in A.baumannii.

Objective To study the effect of Punica granatum( pomegranate) see d oil( PSO) on proliferation and apop-tosis behaviors of breast cancer cells.Methods Fatty acid composition was detected by gas chromatography,breast cancer cells, MCF-7 and MDA-MB-231 were treated with PSO, cell proliferation was observed by MMT, cell apoptosis was analyzed by flow cytometry,and expression levels of proliferation and apoptosis-related proteins were detected by Western blot.Results Punicic acid (PA) was the major fatty acid in PSO(74.41%).PSO could inhibit the proliferation while in-ducing apoptosis in both cell lines in a dose-and time-dependent manner, significantly decrease the expression level of Cox-2 and Bcl-2, increase the expression level of Bax and caspase-3 (cleaved),remarkably upregulate the expression of P53 in MCF-7, and downregulate p53 expression in MDA-MB-231.Conclusion PA may be one of the functional ingredients of PSO which can inhibit proliferation and induce apoptosis in breast cancer cells.These effects are probably mediated by regu-lating the expression of Cox-2, Bcl-2, Bax, caspase-3 (cleaved) and p53.

Objective:To analyze the use status of antibiotics and the resistance of clinic isolate bacteria against the commonly used antibiotics before and after the intervention. Methods:Using the information retrieval systems, the consumption of antibiotics in the inpatients during the 1st quarter of 2012(before the intervention) and the same period of 2013(after the intervention) was com-pared. According to the defined daily dose ( DDDs) , the antibiotics were ranked, and the resistance rate against the commonly used antibiotics was analyzed. Results:Compared with the top ten before the intervention, the top ten after the intervention was changed sig-nificantly, however, cephalosporins was still the main species. After the intervention, the overall decline in DDDs was significant, the separation rate and distribution of bacteria remained stable. ESBLs enzyme production rate of Enterobacteriaceae Escherichia coli was re-duced by 7. 61%, and that of Klebsiella pneumoniae was reduced by 1. 34%, and the resistance rate against the commonly used antibi-otics was in an overall downward trend. The resistance rate of Gram-positive staphylococci against the commonly used antibiotics was de-creased, while that of Gram-positive enterococci showed notable difference. Conclusion:The DDDs of antibiotics and bacterial resist-ance rate are in an overall downward trend in our hospital after the intervention;however, there is still exception. Therefore, the clini-cal antimicrobial susceptibility tests should be performed as soon as possible to help the choice of antibiotics.

Objective:To investigate the effect of dexmedetomidine combined with butorphanol on perioperative analgesia in patients subjected to cardiac surgery.Methods:Sixty-three patients who underwent elective cardiac surgery in Weihai Central Hospital from June 2019 to August 2020 were included in this study. They were divided into propofol + sufentanil group ( n = 21), dexmedetomidine + sufentanil group ( n = 23) and dexmedetomidine + butorphanol group ( n = 19) according to different analgesic methods. Postoperative analgesic satisfaction, Visual Analogue Scale score, hemodynamic changes (heart rate, respiratory rate, systolic blood pressure, diastolic blood pressure) and adverse reactions were compared among the three groups. Results:The satisfaction rate of postoperative analgesia in the dexmedetomidine + butorphanol group was 94.7% (18/19), which was significantly higher than 61.9% (13/21) in the propofol + sufentanil group and 60.8% (14/23) in the dexmedetomidine + sufentanil group ( χ2 = 6.16, 6.57, both P < 0.05). At 4, 12, 24 and 48 hours after tracheal extubation, Visual Analogue Scale score in the dexmedetomidine + butorphanol group were significantly lower than that in the propofol + sufentanil group and dexmedetomidine + sufentanil group (both P < 0.05). At the time of tracheal extubation and at 5 minutes after tracheal extubation, heart rate, respiratory rate, systolic blood pressure and diastolic blood pressure in the dexmedetomidine+butorphanol group were significantly lower than those in the propofol + sufentanil group and dexmedetomidine + sufentanil group (both P < 0.05). The incidence of adverse reactions in the dexmedetomidine + butorphanol group was 10.5% (2/19), which was significantly lower than 23.8% (5/21) in the propofol + sufentanil group and 30.43% (7/23) in the dexmedetomidine + sufentanil group [30.4% (7/23), χ2=21.94, P < 0.001]. Conclusion:Dexmedetomidine combined with butorphanol in cardiac surgery can not only stabilize postoperative blood pressure and heart rate, but also lower the degree of pain and is highly safe.

OBJECTIVE: To explore the genetic basis of two fetuses with an osteogenesis imperfecta (OI) phenotype. METHODS: Two fetuses diagnosed at the Affiliated Hospital of Weifang Medical College respectively on June 11, 2021 and October 16, 2021 were selected as the study subjects. Clinical data of the fetuses were collected. Amniotic fluid samples of the fetuses and peripheral blood samples of their pedigree members were collected for the extraction of genomic DNA. Whole exome sequencing (WES) and Sanger sequencing were carried out to identify the candidate variants. Minigene splicing reporter analysis was used to validate the variant which may affect the pre-mRNA splicing. RESULTS: For fetus 1, ultrasonography at 17+6 weeks of gestation had revealed shortening of bilateral humerus and femurs by more than two weeks, in addition with multiple fractures and angular deformities of long bones. WES revealed that fetus 1 had harbored a heterozygous c.3949_3950insGGCATGT (p.N1317Rfs*114) variant in exon 49 of the COL1A1 gene (NM_000088.4). Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), it was classified as a pathogenic variant (PVS1+PS2+PM2_Supporting) for disrupting the downstream open reading frame resulting in premature translational termination, being de novo in origin, and lacking records in the population and disease databases.For fetus 2, ultrasonography at 23 weeks of gestation also revealed shortening of bilateral humerus and femurs by one and four weeks, respectively, in addition with bending of bilateral femurs, tibias and fibulas. Fetus 2 had harbored a heterozygous c.1557+3A>G variant in intron 26 of the COL1A2 gene (NM_000089.4). Minigene experiment showed that it has induced skipping of exon 26 from the COL1A2 mRNA transcript, resulting in an in-frame deletion (c.1504_1557del) of the COL1A2 mRNA transcript. The variant was inherited from its father and had been previously reported in a family with OI type 4. It was therefore classified as a pathogenic variant (PS3+PM1+PM2_Supporting+PP3+PP5). CONCLUSION The c.3949_3950insGGCATGT (p.N1317Rfs*114) variant in the COL1A1 gene and c.1557+3A>G variant in the COL1A2 gene probably underlay the disease in the two fetuses. Above findings not only have enriched the mutational spectrum of OI, but also shed light on the correlation between its genotype and phenotype and provided a basis for genetic counseling and prenatal diagnosis for the affected pedigrees.
