Objective:To investigate the effect of early gradual diet on reducing delirium in elderly patients with hip arthroplasty.Methods:From January 2018 to January 2020, 74 cases of hip arthroplasty patients aged over 65 years old who were treated in the Third Affiliated Hospital of Sun Yat-sen University were selected as the observation objects. They were randomly divided into experimental group and control group with 37 cases in each group. The experimental group was given early gradual diet on the basis of routine postoperative care, while the control group was given routine postoperative diet on the basis of routine postoperative care. The incidence of postoperative delirium, Pittsburgh Sleep Quality Index (PSQI), patient satisfaction rate, average hospitalization days and average hospitalization expenses were used to evaluate the effect of early gradual diet on reducing delirium in elderly patients with hip arthroplasty.Results:The incidence of delirium in the experimental group was 2.70% (1/37) and 16.22% (6/37) in the control group, the difference was statistically significant ( χ2 value was 3.945, P<0.05); the hospitalization days of the experimental group were (10.68±5.13) d, (13.62±7.19) d in the control group. The difference of hospitalization days was statistically significant ( t value was 2.877, P<0.01). The incidence of difficulty in falling asleep and the satisfaction rate of the experimental group were 8.11% (3/37) and 94.59% (35/37) respectively, and those in the control group were 29.73% (11/37) and 78.38% (29/37) respectively, and the differences were statistically significant ( χ2 value was 5.638, 4.163, P<0.05). Conclusions:Early gradual diet after operation can reduce the incidence of delirium in elderly patients with hip arthroplasty, shorten the average hospitalization days, reduce the incidence of difficulty in falling asleep, improve patients' satisfaction, and help patients to pass through the perioperative period more safely and comfortably.

Objective To investigate the quantitative value of the signal intensity ratio of extraocular muscle and ipsilateral white matter measured by MRI for the evaluation of activity in thyroid-associated ophthalmopathy. Methods A total of 129 patients and 245 eyeballs with thyroid-associated ophthalmopathy were enrolled in this study and this 245 eyeballs were set as thyroid-associated ophthalmopathy group(TAO group). There were 10 patients with newly diagnosed Graves'disease and in the same period and these 20 eyeballs were set as graves'disease group(GD group). 32 normal people from annual physical test excluded thyroid and eye diseases and their 64 eyes were selected randomly for the normal control group(NC group). The signal intensity of the extraocular muscle and the ipsilateral white matter on the MRI images were measured, while did exophthalmos and the width of the inner fat of eyeballs (FWs)measurements in the same time. Results SIR,FWs,and exophthalmos of TAO group were higher than those of the other 2 groups[SIRs:1.71(1.40,2.10)vs 1.26(1.22,1.34)and 1.23(1.14,1.32);FWs:8.04(6.70, 8.71)mm vs 6.16(4.86,7.08)mm and 6.93(6.41,7.65)mm,exophthalmos:20.10(18.56,22.15)mm vs 15.40(14.87,16.60)mm and 14.73(13.40,16.07)mm,all P<0.05]. The reference value of SIR establishing based on SIRs of NC group is less than 1.37. In total 129 TAO patients,55 patients(with 106 eyeballs)have a clinical activity score(CAS). Then,these eyeballs were grouped to activity and non-activity(grouped by CAS≥3),and the baseline group difference of these 2 groups was not statistically significant. The SIRs and exophthalmos of activity group were higher than the non-activity group[SIRs:1.70(1.45,2.33)vs 1.41(1.25,1.75); exophthalmos:(20.38 ± 2.40)mm vs(19.05 ± 3.70)mm,all P<0.05]. But the difference of FWs of these two groups was not statistically significant(P>0.05). The SIRs and CAS had a positive correlation(r=0.580,P=0.000),through the receiver operating characteristic curve(ROC)we get the best diagnostic performance of TAO activity when the SIR≥1.56(sensibility=65.6%,specificity=89.1%,AUC=0.815,P=0.000). Conclusion The signal intensity ratio of extraocular muscle and ipsilateral white matter may discriminate the activity of TAO early as a quantitative indicator, reflecting its efficacy,and is worth clinically generalizing.

OBJECTIVETo construct an eukaryotic expression plasmid for AY358935 gene and explore its function.

METHODScDNA of the AY358935 gene was amplified by reverse transcription-PCR and cloned into pGEM-Teasy. The pGEM-T-AY was validated by sequencing and served as a template for the construction of eukaryotic expression plasmid. The pcDNA3.1-AY recombinant was validated by double enzyme digestion and used for transient transfection of M14 cells. Expression of the AY358935 protein and proliferation of the M14 cells were determined respectively by Western blotting and 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT) colorimetry.

RESULTSThe amplicons of RT-PCR were confirmed to have similar size with the cDNA fragment of the AY358935 gene as well as cloned region of pcDNA3.1-AY. The cloned region of pGEM-T-AY was sequenced to be identical with cDNA sequence of the AY358935 gene. M14 cells were transfected by the AY358935 gene, pcDNA3.1 and liposomes, respectively. After 48 h, expression of the AY358935 protein in M14 cells transfected with the AY358935 gene was significantly higher than other two groups. They also had a significantly higher absorbance value (A=0.74) than other two groups (A=0.39 and 0.46, respectively; P<0.05).

CONCLUSIONAn eukaryotic expression plasmid of the AY358935 gene was successfully constructed. Product of the AY358935 gene may promote the proliferation of M14 cells.

Objective:To retrospectively analyze the urodynamics quality in Southwest China, and find out the main issues of urodynamics quality in Southwest China and try to find out the improvement ways.Methods:In this study, a two-stage sampling method was used.In the first stage, 10 medical institutions in Southwest China were selected by cluster sampling from March to June, 2020.In the second stage, according to the development of UDS in Southwest China, the sample size estimation formula was adopted, and the loss of follow-up rate in reports extraction was considered, the initial sample size was 350. As the workload of UDS in the 10 medical institutions involved in the study was equivalent, 35 urodynamics traces from each medical institution were selected. The initial samples should also meet the inclusion criteria: ①patients with clear medical history and complete clinical data; ②UDS traces were clear; ③UDS system was water filled system; ④age>18, and 150 urodynamic traces were included in the final study. We evaluated the quality of enrolled urodynamics traces, and the quality evaluation standard according to the guidelines established by the International Continence Society (ICS). The evaluation conducted by two independent urologist with more than 10 years working experience. Artifacts were divided into non-technical artifacts: abnormal abdominal pressure changes, urine volume <150 ml when did the uroflow test, and technical artifacts: non-standard zero setting, fail to record all urodynamics parameters, baseline drift, catheter displacement, misjudgment of detrusor physiological contraction and detrusor overactive in voiding phase, misjudgment between detrusor overactive and bladder low compliance in filling phase.Results:non-technical artifacts: 32 cases were found abnormal abdominal pressure changes (21.3%), 21 cases (14.0%) were found when did the uroflow test the urine volume <150 ml, and technical artifacts: Non-standard zero setting in 28 cases (18.7%), fail to record all urodynamics parameters in 8 cases, baseline drift in 16 cases, catheter displacement in 9 cases and misjudgment of detrusor physiological contraction and detrusor overactive in voiding phase in 12 cases, misjudgment between detrusor overactive and bladder low compliance in filling phase in 24 cases (16.0%).Conclusions:At present, the urodynamics quality in Southwest China need to be improved. The main issues were that the operator didn’t obey the basic operation and quality control process, and the operator did not have enough basic knowledge of urodynamics. It can be improved by strictly carry out the operation standard of UDS, identifying and correcting artifacts in time, and promoting the standardized urodynamic training courses.

Objective     To investigate the current status of constipation during postoperative hospitalization and the factors associated with moderate to severe constipation at discharge in lung cancer patients. Methods     Lung cancer patients who underwent surgery in 6 tertiary hospitals in Sichuan Province from November 2017 to January 2020 were enrolled. The MD Anderson Symptom Scale-Lung Cancer Module was used to collect postoperative constipation scores. Unconditional logistic stepwise regression was used to analyze the related influencing factors for moderate to severe constipation on the day of discharge. Results     Finally 337 patients were collected. There were 171 males and 166 females, with an average age of 55.0±10.3 years. Constipation scores of lung cancer patients increased from postoperative day 1 to day 3, and showed a decreasing trend from day 3 to day 7. Moderate to severe constipation was present in 68 (20.2%) patients at discharge. The postoperative hospital stay (OR=0.743, P<0.001) and the dose of morphine used during postoperative hospitalization (OR=1.002, P=0.015) were influencing factors for moderate to severe constipation at discharge in lung cancer patients. Conclusion    Lung cancer patients have the most severe constipation on postoperative day 3. Moderate to severe constipation at discharge is associated with the postoperative hospital stay and the dose of morphine used during postoperative hospitalization.
