To analyze the causes and treatments of high intraocular pressure ( > 21mmHg ) of angle - closure glaucoma underwent compound trabeculectomy 1mo after surgery.
●METHODS: This was a retrospective study of our hospital, from March 2010 to March 2013. Thirty-four (38 eyes) of angle-closure glaucoma patients were collected, who underwent compound trabeculectomy with high intraocular pressure ( > 21mmHg) 1mo after operation. We analyzed the causes and summarized the treatments.
●RESULTS:The causes which lead to early postoperative high intraocular pressure included malignant glaucoma (9 eyes of 8 cases), blood clot and connective tissue block under the scleral flap (15 eyes of 13 cases), hyphema after surgery(5 eyes of 5 cases), sclera flap incision was incarcerated with iris tissue ( 3 eyes of 3 cases ), preoperative high intraocular pressure for a long time(5 eyes of 4 cases), 1 eye of 1 case for unknown reason. After proper treatments, intraocular pressures of all patients were bellowed 21mmHg.
● CONCLUSlON: Early postoperative high intraocular pressure of angle - closure glaucoma underwent compound trabeculectomy is caused by various factors, and the early prevention and timely treatment are key points of a successful operation.

Objective　To investigate the drug resistance of Enterobacter cloacae isolated from blood samples in 75 member units of the Bacterial Drug Resistance Monitoring Network in Hebei, 2016- 2021, so as to provide a basis for rational drug use in clinic. Methods　WHONET 5.6 software was used to retrospectively analyze drug susceptibility of Enterobacter cloacae isolated from 32 secondary hospitals and 43 tertiary hospitals. SPSS19.0 software was used for statistical analysis. Results After removing the duplicate strains, 1 225 strains of E. cloacae were isolated from blood samples of 75 hospitals during 6 years, including 157 strains from secondary hospitals and 1 068 strains from tertiary hospitals. In this study, the resistance of Enterobacter cloacae to 16 kinds of antibiotics was analyzed. The drug resistance rates to cefuroxime (52.4%-67.8%), piperacillin (27.4%-31.2%), ceftazidime (27.8%-35.5%), ceftriaxone (29.5%-45.0%), aztreonam (22.2%-32.3%), cotrimoxazole (21.6%-28.7%) were higher; the resistance rates to amikacin and tobramycin were lower than 15.0%. The resistance rates to imipenem and meropenem were 3.6%-12.3% and 5.1%-11.4%, respectively. The resistance rate to ciprofloxacin in tertiary hospitals was 22.4%, and the resistance rate to cotrimoxazole was 23.9%. Except for these two antimicrobials, the resistance rates to other antimicrobial drugs in tertiary hospitals were higher than that in secondary hospitals. A total of 121 carbapenem-resistant Enterobacter cloacae strains were detected in the past 6 years, with an increasing detection rate (χ2trend=6.305, P=0.012). Conclusions　Enterobacter cloacae has great differences in antimicrobial resistance to different antibiotics, and is sensitive to carbapenems. The drug resistance in tertiary hospitals is generally higher than that in secondary hospitals. Drug resistance monitoring and drug resistance mechanism research should be strengthened to better guide clinical drug use and curb the rise of drug resistance.

Multidrug resistance (MDR) occurs frequently after long-term chemotherapy,resulting in refractory cancer and tumor recurrence.Therefore,combatting MDR is an important issue.Autophagy,a self-degradative system,universally arises during the treatment of sensitive and MDR cancer.Autophagy can be a double-edged sword for MDR tumors:it participates in the development of MDR and protects cancer cells from chemotherapeutics but can also kill MDR cancer cells in which apoptosis pathways are inactive.Autophagy induced by anticancer drugs could also activate apoptosis signaling pathways in MDR cells,facilitating MDR reversal.Therefore,research on the regulation of autophagy to combat MDR is expanding and is becoming increasingly important.We summarize advanced studies of autophagy in MDR tumors,including the variable role of autophagy in MDR cancer cells.

Objective To explore the value of the morphological quantitative indexes and the number of emboli in predicting heart function in patients with acute pulmonary embolism (APE)based on computer-aided diagnosis (CAD)technique.Methods One-hundred and forty-eight APE patients confirmed by CT pulmonary angiography (CTPA)in our hospital.Total number of emboli (N)and three morphological quantitative indexes,including total volume of emboli (V),total length (L)and total maximum cross-section embolism proportion (P)were obtained by CAD.The maximal short axis and area of left and right ventricular (LVd,RVd,LVS,RVS)were measured by hand on axial image to calculate the ratio of maximal short axis of right and left ventricular (RVd/LVd)and ratio of maximal area of right and left ventricular (RVS/LVS).The correlation of the above indexes was analyzed by the Pearson correlation of SPSS 22.0.Results The ranking of the correlation between CAD indexes and the heart function was in the order of V,L,P and N.The correlation between CAD indexes and the right heart function was greater than that of the left heart.The V had the strongest correlation with RVd (r=0.544,P=0.000),RVS (r=0.515,P=0.000),RVd/LVd (r=0.595,P=0.000)and RVS/LVS (r=0.579,P=0.000),respectively.While other the CAD indexes had lower correlation with the heart function (|r|:0.167-0.476,P<0.05),and there was no correlation between the N and the left heart function.Conclusion In embolic morphology and quantitative indexes,the V is the best quantitative index to reflect the change of right heart function in APE,which can reflect dys-function of right heart and severity of pulmonary embolism dis-ease in the APE embolism patient.

OBJECTIVETo investigate the feasibility of peptide mass fingerprinting for non-invasive differential diagnosis of IgA nephropathy (IgAN) from the non-IgA nephropathy (IgAN).?

METHODSAccording to the results of renal biopsy, 56 patients were divided into IgAN group (n=28) and non-IgAN group (n=28), and peptide mass fingerprints were acquired from these patients using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).

RESULTSNine different peptides were identified between IgAN and non-IgAN. The two most distinctive differentially expressed peptides, with peptide peak values of 4476.46 and 1968.10, showed area under curve values of 86.18% and 79.77%. Principal component analysis demonstrated that the accumulated explained variance of the first 8 differential peptides reached 95%, suggesting the feasibility of differential diagnosis of IgAN from non-IgAN. Comparison with the Matrix protein database identified the peptide with a relative molecular mass of 5338.08 as a fragment of mucin 4 inform and the 2082.77 peptide as fragment of α1-II type collagen inform.

CONCLUSIONMALDI-TOF MS is feasible for differential diagnosis of IgAN and non-IgAN and also has great potentials in the classification of the subtypes of other systemic diseases.

BACKGROUNDThe microemboli produced during spontaneous plaque rupture and ulceration and during coronary intervention will reduce coronary reserve and cause cardiac dysfunction. It is though that inflammation caused by the microinfarction induced by the microembolization may play an essential role. It is known that the activation of p38 mitogen-activated protein kinases (MAPK) in both infected and non-infected inflammation in myocardium may cause a contractile dysfunction. But the relation between the activation of p38 MAPK and microembolization is still unknown.

METHODSSprague-Dawley rats were randomly divided into three groups: Sham group, coronary microembolization (CME) group and SB203580 group (n = 10 per group). CME rats were produced by injection of 42 µm microspheres into the left ventricle with occlusion of the ascending aorta. SB203580, a p38 MAPK inhibitor, was injected into the femoral vein after the injection of microspheres to make the SB203580 group. Left ventricular ejection fraction (LVEF) was determined by echocardiography. The protein concentration of P38 MAPK in the myocardium was assessed by Western blotting. The relative expression of mRNA for tumor necrosis factor (TNF)-α was assessed by the technique of semi-quantitative polymerase chain reaction amplification.

RESULTSLVEF was depressed at three hours up to 12 hours in the CME group. Increased p38 MAPK activity and TNF-α mRNA expression were observed in the CME group. The administration of SB203580 partly inhibited p38 MAPK activity, but did not fully depress the TNF-α expression, and partly preserved cardiac contractile function.

CONCLUSIONSp38 MAPK is significantly activated by CME and the inhibition of p38 MAPK can partly depress the TNF-α expression and preserve cardiac contractile function.
