Objective:This study aims to evaluate the clinical effect and adverse reactions of oxaliplatin or irinotecan plus capecitabine treatment for colorectal liver metastases. Methods:Data from 125 cases of colorectal liver metastasis patients were continuously enrolled and randomized into two groups, i.e., 63 in group one (treatment group) and the other 62 in group two (the control group). Capecitabine was administered at 1 000 mg/m2 doses, twice a day from d1 to d14, to all patients. Irinotecan was administered at 150 mg/m2 in d1 to group one, and oxaliplatin was administered at 130 mg/m2 in d1 to group two. The drug administration cycle lasted for 21 days in both regimens, with at least 6 administration cycles. The total course was for 6 months at most. The therapeutic efficacy, median progression-free survival time, median survival time, short-term clinical effect, and adverse drug reaction were monthly determined. Results:The overall response rates and disease control rates were 33.3%and 66.7%in group one, respectively, and 35.5%and 70.9%in group two, respectively, with no significant differences between the groups (P>0.05). The median survival time and median progression-free survival time were 14 months and 5 months in group one, respectively, and 12 months and 5 months in group two, with no significant differences between the two groups (P>0.05). The level-Ⅲand-Ⅳadverse drug reactions mainly include hematological toxicity, gastrointestinal reactions, and hand-foot syndrome. The diarrhea frequency is obviously higher in group one than in group two, and the difference between the two groups is sta-tistically significant (P<0.05). No significant differences were observed in the other adverse reactions between the groups (P>0.05). Conclusion:The Oxaliplatin or Irinotecan plus Capecitabine treatment is effective for colorectal liver metastases, which enhances survival rate and reduces patient suffering because of it has less side effects and good tolerance. The treatment must be further generalized and clinically applied.

Objective To compare the different ways of alkaline mouthwash slobber use in preventing the oral infection in patients with fever. Methods The patients who satisfied the requirements were involved and randomly divided into A, B and C group. A group did not use alkaline mouthwash; B group prescribed alkaline mouthwash slobber following the doctor's advice; C group received propaganda and demonstration of intensive use of the alkaline mouthwash, and then used the slobber in right way under the surveillance of nurses. The infection rates of oral ulcer and oral leukoplakia were compared and analyzed among the three groups. Results The incidence rates of oral ulcer and oral leukoplakia gradually decreased among the three groups and the differences had statistical significance (χ2=9.243,P=0.010;χ2=6.495,P=0.033).Compared with A group, there was no significant differences in the rates of oral ulcers and oral leukoplakia between Group A and B(OR=0.486, 95%CI:0.113-2.087;OR=0.557, 95%CI: 0.120-2.583), but the incidence rates of oral ulcers and oral leukoplakia gradually decreased(OR=0.024, 95%CI:0.002-0.293;OR=0.036, 95%CI:0.003-0.448)in C group. Conclusions Strengthening use of alkaline mouthwash slobber is more effective in preventing oral infection in patients with fever compared with the routine way of mouthwash use.

Objective To analyze the serum levels of bone morphogenetic protein 4(BMP4)and nerve ax-on guidance factor 4(Netrin-4)in patients with diabetic retinopathy(DR),and to study their relationship with disease stage and prognosis.Methods A total of 186 patients with type 2 diabetes admitted to the hospi-tal from October 2019 to November 2022 were selected as the research objects.According to the presence or absence of retinopathy,they were divided into DR Group(108 cases)and non-DR group(78 cases),and 100 healthy people in the hospital were selected as the control group.According to the stage of DR,the DR pa-tients were divided into stage Ⅰ(19 cases),stage Ⅱ(14 cases),stage Ⅲ(22 cases),stage Ⅳ(23 cases),stage V(18 cases)and stage Ⅵ(12 cases).According to the visual impairment after treatment,the DR patients were divided into a good prognosis group(72 cases)and a poor prognosis group(36 cases).Serum BMP4,Ne-trin-4,fasting plasma glucose(FPG),glycated hemoglobin Alc(HbA1c),systolic blood pressure(SBP),dias-tolic blood pressure(DBP),triglyceride(TG),total cholesterol(TC),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C)were detected by enzyme-linked immunosorbent as-say.The serum levels of BMP4 and Netrin-4 in DR patients with different disease stages were analyzed.Multi-variate Logistic regression was used to analyze the influencing factors of DR,and the serum levels of BMP4 and Netrin-4 in DR patients with different prognosis were analyzed.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of poor prognosis in DR patients.Results The FPG,HbA1c,SBP,DBP,TG,TC,BMP4,Netrin-4 levels in DR group were higher than those in control group and non-DR group,while HDL-C level was lower than that in control group and DR group(P＜0.05).There were significant differences in serum BMP4 and Netrin-4 levels between DR patients with different disease stages(P＜0.05).HbA1c,BMP4 and Netrin-4 levels were influencing factors for the occurrence of DR(P＜0.05).The serum levels of BMP4 and Netrin-4 in the poor prognosis group were higher than those in the good prog-nosis group(P＜0.05).The combination of serum BMP4 and Netrin-4 levels in the diagnosis of poor progno-sis of DR patients was better than that of each index alone.Conclusion The serum levels of BMP4 and Ne-trin-4 are increased in DR patients,which can assist in the evaluation of the disease stage of the patients.The combination of BMP4 and Netrin-4 has a good effect in the diagnosis of poor prognosis of patients.
