Objective To evaluate the early diagnostic value of 1,3-β-D glucan(BG) and galactomannan(GM) test for invasive fungal infections(IFI)in intensive care unit(ICU) patients.Methods From 2013 to 2015,the concentration of serum BG and GM were detected in 452 cases of ICU patients,including 182 cases with diagnosis of IFI,46 cases with possible diagnosis of IFI and 224 cases of non-IFI.The diagnostic performance of BG,GM and combined test were analyzed.Results The sensitivity,specificity,positive predictive value(PPV) and negative predictive value(NPV)of BG test were 75.0%,80.4%,75.8%,79.6%.Those of GM test were 25.80%,85.7%,59.5% and 58.7%.The sensitivity and specificity of BG and GM combined test were 87.4% and 94.7% respectively.Conclusion BG and GM combined test could improve the diagnostic efficiency,reduce the false positive rate and false negative rete,which might be helpful for the early diagnosis of IFI in ICU patients.

AIM: To study the interaction effects of Astragalus polysaccharide(APS) and total glucosides of paeony(TGP) with various dosage on the platelet aggregation. METHODS: Platelet aggregation was estimated by the turbidimetric method. The best interaction effects were determined by uniform design method. RESULTS: APS showed apparent anti-platelet effects and better combination with TGP,and the ratio of 121 was the best one. CONCLUSION: APS concerted with TGP inhibits platelet aggregation.

Tear is a complex fluid mainly secreted by lacrimal gland.It is a complex body fluid,which may contain thousands of protein/peptides and other molecules.Studies have determined that the changes in the chemical compositions of tears play an important role in some diseases and their progression.Tear components including protein,lipid and metabolites,which is easy to be obtained,not only can be used for biomarkers,can also be used to study an eye the onset of systemic disease process.Measuring the changes in composition of tear may be used to determine the critical path of the disease development,provide a new possibility for prevention and treatment.This article reviews the ophthalmic applications of tear markers in the systemic disease,which has not been determined so far.

In recent years,there are many studies have reported that a small pupil syndrome appeared during routine phacoemulsification in patients with current or previous use of alpha-1 adrenergic receptor antagonists,with these clinical manifestations:an iris that appears floppy as it billows during normal irrigation and aspiration in the anterior chamber,a tendency for the iris to prolapse and progressive intraoperative miosis during surgery,which called intraoperative floppy iris syndrome This article mainly reviews the mobidity,pathogenesis,clinical features,complications,prophylaxis and treatment of the intraoperative floppy iris syndrome.

Objective: To investigate the willingness to pay integrated medical and elderly care services and identify the influencing factors among the elderly in Hohhot City, Inner Mongolia, so as to provide insights into promoting integrated medical and elderly care services. Methods: The elderly at ages of 60 years and older were sampled using a convenient sampling method from public venues in four districts of Huimin, Saihan, Yuquan and Xincheng in Hohhot City from June to December 2021. Basic characteristics, health and disease burdens, social support and willingness to pay integrated medical and elderly care services were collected, and factors affecting the willingness to pay integrated medical and elderly care services were identified among the elderly using a multiple linear regression model. Results: A total of 1 008 valid questionnaires were recovered, with an effective recovery rate of 96.74%. The respondents included 519 men (51.49%) and 489 women (48.51%), and had a mean age of (69.47±6.42) years. The monthly average fees of willingness to pay integrated medical and elderly care services were (2 076.49±36.79) Yuan, and there were 636 participants with 2 000 Yuan and less monthly average fees of willingness to pay integrated medical and elderly care services (63.10%). Multiple linear regression analysis showed that place of residence (β=180.832), satisfaction with housing (satisfied, β=-140.760), physical self-care ability (completely self-care: β=-238.244; mostly self-care: β=-254.557), burdens of disease diagnosis and treatment (able to afford: β=452.488; partly afford: β=228.626), monthly income (β=347.144), expenses of medications (β=0.019) and total score of social support (β=17.116) were factors affecting the willingness to pay integrated medical and elderly care services among the elderly. Conclusions The willingness to pay integrated medical and elderly care services among the elderly in Hohhot City is associated with place of residence, monthly income, satisfaction with housing, physical self-care ability, burden of disease diagnosis and treatment, expenses of medications and social support.

Objective To study the effect and mechanism of arsenic trioxide on the motility, metastasis and invasion of osteosarcoma in vitro. Methods Wound healing assay, migration assay, invasion assay and Western-blot were performed to study the effect of arsenic trioxide on metastasis of osteosarcoma. Results Through screening MNNG cell was selected to perform the following research. After treatment of As_2O_3, the ability of MNNC cell flattening and spreading along the edges of the wound was inhibited, and the number of MNNG cells with migration and invasion in As_2O_3 - treated group was significantly less than in control group. Arsenic trioxide treatment also resulted in down-regulation of MMP-9. Conclusion This study is the first to report the effectiveness of arsenic trioxide as an inhibitor of osteosarcoma migration and invasion and the mechanism may be down-regulation of MMP-9.

Objective To evaluate the value of reducing radiation dose with decreased size of ECG-pulsing windows and influence on image quality in dual-source CT coronary angiography. Methods 120 patients with stable heart rate(HR) were divided into four groups according to HR and the rang of ECG-pulsing windows in dual-source CT coronary angiography: HR ＜ 70 bpm and 61% ～ 77% R-R interval of ECG-pulsing windows, HR ＜ 70 bpm and 25% ～ 80% R-R interval of ECG-pulsing windows,HR ＞ 80 bpm and 31% ～47% R-R interval of ECG-pulsing windows, and HR ＞ 80 bpm and 25% ～ 80%R-R interval of ECG-pulsing windows was employed, respectively. The radiation dose parameters were recorded and image quality scores were performed. The image quality and radiation dose between two slow HR groups and between two fast HR groups were compared respectively. Result The effective doses were (7.06 ± 2. 13 ), ( 11.34 ± 3.65 ), ( 6. 67 ± 1.97 ) and ( 9. 92 ± 3. 15 ) mSy for four groups, respectively.The effective dose was decreased by 37.74% for slow HR and by 32. 76% for fast HR using narrow ECG-pulsing windows. There was no difference on image quality between two slow HR groups and two fast HR grouvs. Concluslons The proper application of narrow ECG-pulsing windows can reduce radiation exposure significantly to stable slow or fast HR patients in dual-source CT coronary angiography withont sacrificing the image quality.

Objective To observe the effect of effective monomer of Kangxianling prescription on renal function and extracellular matrix composition of 5/6 nephrectomy rats model, and provide basis for the screening of effective traditional Chinese medicine of anti-renal fibrosis. Methods Sixty SD rats were randomly divided into normal group, model group, chrysophanol group, salvianolate A group, oleanolic acid group and losartan group. The kidney fibrosis model was made by operation. Two months after intervented by correspong drugs, renal pathological changes of all groups were observed, the levels of renal function indexes were detected, and real-time PCR assay was used to detect laminin (LN), fibronectin (FN), type Ⅲ collagen (C-Ⅲ), type Ⅰ collagen (C-Ⅰ) mRNA expression in rat kidney tissue. Results SCr and BUN in model group increased significantly compared with the normal group (P<0.01). SCr and BUN in salvianolate A group decreased significantly compared with the model group (P<0.05, P<0.01). BUN in salvianolate A group decreased significantly compared with the losartan group (P<0.01). The expression of C- ,Ⅲ C-Ⅰand LN were reduced by effective monomer of Kangxianling prescription. Conclusion Effective monomer of Kangqianling prescription can inhibit renal fibrosis through reducing the expression of extracellular matrix components, thereby improve the renal function.
