Objective To explore the application of serum signal transducers and activators of transduction 3(STAT3)and SMAD4 expression levels in the early diagnosis and clinical staging of primary glaucoma patients.Methods 86 patients with primary glaucoma admitted to Cangzhou Eye Hospital from August 2021 to May 2023 were selected as the study group,according to the clinical symptoms and visual examination results of the research group,they were divided into mild injury stage(n=30),moderate injury stage(n=34)and severe injury stage(n=22).Another 86 healthy individuals who underwent physical examinations in Cangzhou Eye Hospital during the same period were collected as the control group.Enzyme linked immunosorbent assay(ELISA)was applied to detect the expression levels of serum STAT3 and SMAD4.Multivariate Logistic regression was applied to analyze the relevant factors affecting clinical staging of primary glaucoma,receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum STAT3 and SMAD4 in patients with moderate/severe primary glaucoma injury.Results The expression levels of serum STAT3(13.96±3.45 ng/ml)and SMAD4(11.23±2.85 ng/ml)in the study group were obviously higher than those in the control group(9.83±1.72 ng/ml,7.78±1.95 ng/ml),the differences were statistically significant(F=13.085,17.513,all P＜0.05).The expression levels of serum STAT3(11.88±2.52 ng/ml,13.85±3.51 ng/ml,16.96±4.63 ng/ml)and SMAD4(9.15±1.95 ng/ml,11.23±2.83 ng/ml,14.08±4.12 ng/ml)in patients with primary glaucoma in mild,moderate and severe injury groups were gradually increased,the differences were statistically significant(F=13.085,17.513,all P＜0.05).There was a statistically obvious difference in intraocular pressure among patients with mild,moderate(24.21±5.03 mmHg,28.16±6.31 mmHg,32.26±7.57mmHg),and severe injuries(F=10.577.P＜0.05).serum STAT3[OR(95%CI)=2.728(1.409～5.281)],SMAD4[OR(95%CI)=2.849(1.507～5.387)],and intraocular pressure[OR(95%CI)=2.435(1.094～5.417)]were risk factors affecting clinical staging of primary glaucoma(all P＜0.05).The area under the curve(AUC)of the combined diagnosis of serum STAT3 and SMAD4 for moderate/severe injury in patients with primary glaucoma was 0.963(95%CI:0.899～0.992),which was superior to their respective individual diagnoses(Z =2.558,1.961;P=0.010,0.049),their sensitivity and specificity were 96.43%and 83.33%,respectively.Conclusion The higher the expression levels of STAT3 and SMAD4 in serum,the more severe the clinical symptoms in patients.The combined detection of the two has good diagnostic value for patients with moderate/severe injury.

Objective We observed the effect of dexamethasone ointment on preventing phlebitis induced by vinorelbine. Methods Patients with malignant tumor who received chemotherapy of vinorelbine through peripheral superficial vein injection were divided into the observation group (70 cases) and the control group (72 cases) according to the date of hospitalization. All patients received vinorelbine four times averagely. Patients in the observation group was given dexamethasone ointment along punctured superficial vein. Patients in the control group received routine nursing measure. The incidence rate, time and degree of phlebitis was compared between these groups. Results The incidence rate and degree of phlebitis was lower than those of the control group (P< 0.01, P< 0.05). The incidence time of phlebitis in the observation group was also later than that of the control group (P<0.05). Conclusion Local application of dexamethasone ointment could effectively reduce the incidence of superficial phlebitis caused by vinorelbine chemotherapy.

In this study we deliberated over the principles and methods and then took the noninvasive continuous measurement of blood glucose concentration through the skin of rabbits. The glucose oxidase sensor was made by covalent immobilization. The best making method of sensor and stable working condition were sifted. Ten female and 10 male adult white rabbits were allocated into the groups of the ante-ultrasound and post-ultrasound, the injection of glucose, and the high and low frequency ultrasounds. After the skin surface was treated by high or low frenquency ultrasound for 5 minutes on the rabbits, obvious changes (P < 0.01) of post-ultrasound and post-injection of glucose were observed by means of glucose oxidase sensor and microcurrent apparatus. After application of ultrasound to the skin of rabbits, the penetration of glucose through the rabbit skin increased obviously. The change of microcurrent signal that was exchanged by the glucose sensor correlated positively with the concentration of glucose of rabbit body. The blood glucose can be tested by the glucose sensor on the skin surface of living animal.
