The lipoprotein-associated phospholipase A2 (Lp-PLA2), a subtype of the phospholipase A2 superfamily, is produced primarily by macrophages and lymphocytes. Lp-PLA2specifically hydrolyzes oxidized phospholipids on oxidized low-density lipoprotein particles,resulting in production of lysophosphatidylcholine and oxidized fatty acids. Lp-PLA2 is expressed in atherosclerotic plaques and in macrophages within a fibrous cap of unstable plaque.Studies haw shown that the plasma Lp-PLA2 activity increases significantly in patients with ischemic stroke, and Lp-PLA2 may become an independent risk factor for predicting ischemic cerebrovascular events. The selective Lp-PLA2 inhibitor can reduce the inflammatory response,enhance the stability of plaques, and inhibit the formation of atherosclerotic plaques, and may become a new class of drugs for preventing the formation of atherosclerotic plaques.

Mechanical ventilation plays an important role in the treatment of preterm infants,especially respiratory problems.With improvement in both antenatal and neonatal care and therapeutic strategies,premature babies are surviving more than ever.However,the incidence of bronchpulmonary dysplasia remains high which affects the clihical outcomes of premature infants.Non-invasive respiratory support techniques have been used in attempts to decrease lung injury and the complications of preterm infants.This review will focus on various ventilation modalities for managing preterm infants with respiratory failure and lung protective ventilation strategies to minimize lung injury in preterm infants.

A case of mandible plasma cell myeloma is reported.Plasma cell myeloma is a monoclonal neoplastic proliferation of plasma cells of bone-marrow derivation,usually multi-centric but jaw bones are rarely involved.The treatment requires precise pathological diagno-sis.The prognosis of solitary jaw bone lesions can be good after treatment.

Objective To investigate the correlation between the NADPH oxidase p22phox-A930G polymorphism and hypertensive intracerebral hemorrhage in Chinese Han population in Shanghai area.Methods The patients with hypertensive intracerebral hemorrhage and normal controls were enrolled.The polymerase chain reaction and the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were used to detect the genotypes and alleles of NADPH oxidase p22phox-A930G.Results A total of 128 patients with hypertensive intracerebral hemorrhage and 151 healthy controls were enrolled.The levels of systolic blood pressure,diastolic blood pressure,glucose,and triacylglycerol,as well as the proportions of smoking and alcohol consumption in patients of the hypertensive intracerebral hemorrhage group were significantly higher than those of the control group (all P＜ 0.05).There were significant differences in AA,AG,and GG genotypes (42.2％,44.5％,and 13.3％ vs.63.6％,27.8％,and 8.6％,x2 =12.757,P =0.002) and in A and G allele (64.5％ and 35.5％ vs.77.5％ and 22.5％ ;x2 =8.734,P=0.001) frequencies between the hypertensive intracerebral hemorrhage group and the control group.Multivariatelogistic regression analysis showed that systolic blood pressure ≥ 140 mm Hg (1 mm Hg =0.133 kPa) (odds ratio [OR] 13.952,95％ confidence interval [CI] 7.242-26.879; P ＜ 0.001),apolipoprotein A ≥ 0.99 mmol/L (OR 3.139,95％ CI 1.012-9.733; P =0.048),and AG +GG genotype (OR 2.333,95％ CI 1.253-4.342; P=0.008) were the independent risk factors for hypertensive intracerebral hemorrhage.Conclusions Among the Chinese Han population in Shanghai area,the NADPH oxidase p22phox-A930G polymorphism is an independent risk factor for hypertensive intracerebral hemorrhage.

Objective:To study the integrated information nursing mode of perioperative medical care under the multidisciplinary cooperation of hip fracture in the elderly patients, provide reference for perioperative nursing of elderly hip fracture.Methods:A total of 1 019 patients with hip fracture from May 2018 to May 2019 in Beijing Jishuitan Hospital were randomly selected as the study object, and the non synchronous control was used for the study. From May to December 2018, 527 elderly patients with hip fracture in orthopaedic department of general trauma were taken as the control group, adopting the traditional treatment and nursing mode; from January to May 2019, 492 elderly patients with hip fracture in elderly trauma orthopaedics department were taken as the intervention group. Under the multidisciplinary cooperation, the information-based nursing mode of integrated medical care was implemented, and a multidisciplinary integrated medical care team was established. The information-based platform was used to optimize the clinical nursing path, and standardized, individualized and continuous nursing scheme was developed. The time from visit to hospitalization, the time from hospitalization to operation, hospitalization time, incidence of more than moderate pain, incidence of venous thromboembolism, incidence of stress injury, incidence of delirium and satisfaction of patients and their families at discharge were compared between the two groups.Results:The number of patients in the intervention group was higher than that in the control group within 4 and 24 hours. The rate of operation in 48 h increased from 8.0%(42/527) to 50.0%(246/492), and the rate of operation in 1 week increased from 70.0%(369/527) to 99.0%(487/492). Compared with the control group, the incidence of more than moderate pain in the intervention group decreased from 85.0%(448/527) to 2.0%(10/492), the incidence of venous thromboembolism in the hospital decreased from 12.0%(63/527) to 4.1%(20/492), and the incidence of pressure injury in hip fracture in the elderly decreased from 2.1%(11/527) to 0.2%(1/492); the incidence of delirium in the hospital decreased from 21.1%(111/527) to 8.1%(40/492); the hospital stay was shortened from (13.42 ± 3.36) d to (7.26 ± 2.03) d, and the satisfaction of patients and their families increased from 60.9%(321/527) to 95.9%(472/492). There were statistical significance between the two groups (χ 2 values were 4.157-708.006, t value was -35.119, P<0.05 or 0.01). Conclusions:The information-based nursing mode of integrated medical care under the multidisciplinary cooperation can adapt to the development of hip fracture in the elderly, which is conducive to the accelerated rehabilitation of patients.

Objective:To analyze and discuss the factors of seizure induced by imipenem/cilastatin.Method: The reports of seizure induced by imipenem/cilastatin from CBMDisc(1971-2006)and CHKD(1994-2006)were re- viewed and analyzed with Excel.Result:28 cases of seizure induced by imipenem/cilastatin were collected,including 20 men and 8 women with the principal primary respiratory infection with an average age of 66.5.Seizure occurred as early as 10 min.after the medication,and occurred latest in the fourth day of the medication.22 cases showed grand mal seizure and 6,partial seizure with a duration ranging from 20s to 30min and with a frequency of eight seizures.18 cases discontin- ued the administration,and 8 cases took lower daily dosage,in which some were given antiepileptic drugs or other adjunc- tive therapy,and 2 cases were not treated at all.All the cases recovered and were discharged from hospital except one who died from his circulation failure and respiration failure.The cause-effect relations of the relevance evaluation of seizures e- yoked by imipenem/cilastatin were as follows:1 sure case,26 probable cases,and 1 possible case.Conclusion:Seizure can be induced by imipenem/cilastatin,Owhich should be rationally used.More attention should be paid in clinic so as to ensure a safe medication.

Injury to anterior cruciate ligament (ACL) is the most common lesions of the knee joint. Reconstruction of ACL has been the primary treatment for the instability of the knee. Compared with the traditional reconstruction with patellar tendon, the hamstring tendon has many advantages, such as less damage to the donor site and less incidence of antero-patellar or kneeling pain. This paper highlights the basic and clinical research on ACL reconstruction.
