This paper reports the nursing experience of 5 cases of Charcot's arthropathy undergoing rotating hinge prosthesis knee replacement. The nursing care focused on psychological nursing, preoperative examinations, control of blood glucose and treatment of syphilis during preoperative period, as well as wound care, management of drainage tube, prevention of complications and early functional exercise during the postoperative period. All cases were followed up through 6 to 60 months. The short-term outcomes were satisfying. One patient suffered from periprosthetic femoral fracture at 23-month after the operation, and healed up eventually after open reduction and internal fixation.

Objective:To establish a HPLC method for the simultaneous determination of adenosine,genistein and 5-hydroxymel-lein in Xylarin nigripes powder.Methods:The chromatographic separation was carried out on a Pntulips@BP-C18column (250 mm× 4.6 mm,5 μm) at 35℃. The mobile phase consisted of acetonitrile-0.1% formic acid with gradient elution at a flow rate of 1.0 ml ·min-1,and the detection wavelength was 254 nm. Results:The linear range of adenosine was 0.162-1.62 μg(r=0.999 2). The average recovery was 98.12% and the RSD was 1.32% (n=6). The linear range of genistein was 0.02-0.2 μg(r=0.999 9). The average recovery was 98.89% and the RSD was 1.10% (n =6). The linear range of 5-hydroxymellein was 0.022-0.22 μg(r =0.999 9). The average recovery was 99.87% and the RSD was 0.98% (n=6). Conclusion:The method can be used to determine the contents of adenosine,genistein and 5-hydroxymellein,which provides the basis for the quality control and the further research of Xylaria nigripes.

Objective:To investigate the safety, economic effect, and short-term clinical efficacy of ambulatory total hip arthroplasty (THA) in the treatment of hip osteopathy within.Methods:This study retrospectively reviewed patients who underwent 48-hour outpatient THA and conventional primary THA from July 2020 to July 2021. Gender, age, body mass index (BMI), clinical diagnosis, place of resident, length of hospital stay, duration of the surgery, hemoglobin, albumin, C-reactive protein (CRP) and D-dimer before and 1 day after surgery, the visual analogue scale (VAS) was obtained postoperative day 2, hip joint modified Harris score before and 1 month after surgery, readmission and reoperation within 1 month after operation as the data of evaluations were extracted and compared in this study.Results:A totally of 150 cases were involved in this study, which including 75 cases with 48-hour outpatient primary THA and 75 cases with conventional primary THA. There was no significant difference between the two groups in terms of age, sex, BMI, education level, preoperative diagnosis, and preoperative Harris score ( P>0.05), but a significant difference was found in term of residence (χ 2=6.29, P=0.043), that the patients in the outpatient group were all from Zhejiang Province and 48% (36/75) of them were from Hangzhou City. While, in the conventional group, 6 patients were from other provinces. The length of stay was 2.13±0.52 days and operation time was 59.73±18.91 minutes in the outpatient group, which were both shorter than those (6.71±1.44 days and 66.91±22.40 min) in the conventional group ( t=25.91, P<0.001 for the length of hospital stay; t=2.12, P=0.036 for operation time). Compared with the conventional group, outpatient group saved the average hospital cost (4.60±0.44 vs. 5.20±0.72 ten thousand yuan, t=6.16, P<0.001). The VAS on the second day after surgery 3.45±0.75 was higher in the outpatient group than in the conventional group (3.45±0.75 vs. 3.16±0.94 points, t=2.09, P=0.039). The modified Harris score was without statistical significance ( t=0.42, P=0.677) 1 month after surgery in both groups. 75 patients in the outpatient group, 7 patients delayed discharge (were not discharge within 48 hours), and the rate of delayed discharge was 9.3%. Reasons for delayed discharge included poor pain control in two cases, one case had postoperative nausea and vomiting, one case had failed to meet rehabilitation standards, hypotension in one case, the intraoperative infection in one case and postoperative fever within 48 hours in one case. Conclusion:Outpatient THA can reduce the length of hospital stay, operative time and total cost of hospitalization. It has similar safety and early clinical efficacy as conventional THA. However, a small proportion of patients would delay discharge.

Objective:To improve the quality standard for Jinhuanglian oral liquid. Methods:The three herbs in the preparation, Honeysuckle, Scutellaria Baicalensis Georgir and St John's Wort, were identified by TLC qualitatively. The content of chlorogenic acid in Lonicerae Japonicae Flos was determined by HPLC. The chromatographic separation was carried out on a Promosil C18 (250 mm × 4. 6 mm,5 μm) column at 25℃. The mobile phase consisted of acetonitrile-0. 4% phosphoric acid (10 :90) with gradient elution at a flow rate of 1. 0 ml·min -1 , and the injection volume was 10μl. The detection wavelength was 327 nm. Results:The spots in TLC were clear without any interference. The linear range of chlorogenic acid was 5.325-170.400 μg·ml-1(r=0.9998). The average recovery was 97. 95% and the RSD was 2. 04%(n=6). Conclusion:The method is reliable and easy to operate,which can be used as the quality control method for Jinhuanglian oral liquid.
