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 explore the expression of FAT1 in esophageal squamous cell carcinoma (ESCC) tissues, and its effect on cell proliferation. Methods: The expression levels of FAT1 protein in human ESCC tissues and matched adjacent normal tissues were determined by immunohistochemistry (IHC). Lentivirus based knockdown of FAT1 was carried out in YSE2 and Colo680N cell lines and 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H tetrazolium bromide (MTT) assays was performed to examine the effect of FAT1 on the proliferation of these ESCC cells. Colony formation assay was used to detect the colony formation ability. Flow cytometry was performed to analyze the cell cycle and apoptosis. The expression levels of cell cycle markers in FAT1 knock out ESCC cell lines were detected by real-time quantitative reverse transcription polymerase chain reaction(qRT-PCR) and Western blot. Results: The relative expression of FAT1 in ESCC tissues was 66.97±21.53, significantly lower than 78.13±16.76 of adjacent normal tissues(P<0.05). Knockdown of FAT1 promoted cell proliferation and colony formation. In YSE2 cell, the division time in negative control (NC) group was (1 570±51) min, significantly longer than (1 356±31) min in shFAT1 group. In Colo680N cell, division time in NC group was (1 532±53) min, significantly longer than (1 290±30) min in shFAT1 group (P<0.05). Knockdown of FAT1 promoted G1-to S-phase transition and resulted in the upregulation of CDK4/CDK6/CCND1. Conclusion FAT1 inhibits the proliferation and G1-to S-phase transition of ESCC cells through regulating the protein expression of CDK4/CDK6/CCND1 complex.

Objective:To analyze the expression of LETM2 in KYSE150 and ECA109 cell lines and its effect on the proliferation, migra-tion, and invasion of esophageal squamous cell carcinoma (ESCC). Methods:The expression level of the LETM2 protein in 90 paired hu-man ESCC tissues and matched adjacent normal tissues was determined through immunohistochemistry. The expression level of LETM2 in ESCC cell lines was detected by real-time PCR and Western blot. The expression levels of LETM2 in KYSE150 and ECA109 cell lines were knocked down using lentivirus. MTT assays were performed to examine the effect of LETM2 on the proliferation of ESCC cells. Colony formation assay was used to detect the colony formation ability. Flow cytometry was performed to analyze the cell cycle. The effect of LETM2 depletion on the migration and invasion of ESCC cells was determined by Transwell assay. Results:LETM2 expres-sion was frequently upregulated in the ESCC tissues than in the adjacent normal tissues. The suppressed exogenous expression of LETM2 led to the inhibition of cell proliferation and colony formation. However, cell migration and invasion were not affected. The re-sults on the cell cycle distribution revealed that LETM2 knockdown acts as a negative regulator of the cell cycle at the G1 to S phase transition. Conclusion:LETM2 acts as a tumor-driven gene in the development and progression of ESCC. This finding suggests that LETM2 can be used as an efficient prognosis biomarker and a potential therapeutic target for ESCC.

Objective To investigate the changes in cognitive function in patients with early Parkinson's disease (PD) in a 5-year follow-up.Methods A total of 181 PD and 173 normal participants were recruited between January 2009 and January 2012 at the Department of Neurology,the Second Hospital of Jiaxing City.Regression analysis was used to evaluate the risk factors of cognitive impairment,and changes in subdomains of the Montreal Cognitive Assessment (MoCA) were compared annually with baseline data.Results Baseline clinical data were similar between the two groups.The level of cognitive impairment was positively correlated to the age of onset and the Hamilton Anxiety Scale (H AMD) (t =3.326,P＜ 0.05;t =5.211,P＜0.01),and negatively correlated to education level (t=-2.505,P＜0.05).There were no statistical differences in the first (26.5 ± 2.6),second (26.3±3.2) and third year (25.9±2.9) in the total scores of MoCA,which significantly increased in the forth (24.4 ± 2.3,P＜0.05) and fifth (24.1 ± 1.2,P＜0.05) year compared with baseline levels (26.7±2.9).However,in the control group,differences between any two years in total scores were not statistically significant (all P＞0.05).Seven subdomains of MoCA were attenuated,and four of them were significant different between the groups,including delayed recall,attention,abstraction task and orientation after the forth year of follow-up (all P ＜ 0.05).Meanwhile,visuospatial execution capacity was attenuated before the third year,and then rose markedly (P＜0.05).In the control group,the between-year differences of seven subdomains were not statistically significant (all P＞0.05).Conclusions Cognitive function of PD patients decreases significantly in some domains,such as delayed recall,attention,abstraction task and orientation after a five-year followup.

Objective To analyze the clinical features of Parkinson's disease (PD) combined with chronic pain in the elderly.Methods A total of 366 idiopathic PD patients experiencing pain were enrolled and divided into two groups:the elderly group (n=289) and the young group (n=77).Rating scales including Visual Analogue Scale (VAS),Unified Parkinson's Disease Rating Scale (UPDRS),Hoehn Yahr (H-Y) Scale,Self-rating Anxiety Scale (SAS),Self rating Depression Scale (SDS) and Brief Pain Inventory (BPI) were evaluated.Results Compared with the young group,the elderly group had evidently higher scores of UPDRSⅡ,Ⅱ,Ⅳ,H-Y Scale,VAS as well as five sub-items of BPI including daily living,working,sleeping,walking ability and social communication [(13.7±5.3) vs.(12.3±6.3),(27.3±12.9)vs.(23.3±9.6),(2.3±2.2)vs.(1.7±1.3),(2.4± 1.0)vs.(2.1±0.9),(63.3±25.6)vs.(56.6±25.0),(5.3±2.7)vs.(4.6±2.7),(5.9±3.2)vs.(5.1±2.8),(6.3±2.5)vs.(5.6±2.6),(4.7±3.1)vs.(3.8±2.0),(3.2±2.1)vs.(2.6±2.5),t=1.976,2.539,2.287,2.381,2.050,2.021,1.997,2.165,2.420,2.134,respectively,all P＜0.05].No significant differences were found in SAS,SDS or other sub-items of BPI such as life pleasure and mood scores between the two groups (all P＞0.05).Compared with the young group,patients in the elderly group had a higher ratio of two or more pain types associated with PD[41.2％ (119/299)vs.23.4％ (18/77),x2=8.190,P＜0.05],but a lower ratio of pain-related treatment [29.76％ (86/299)vs.51.95％ (40/77),x2=13.260,P＜0.05].Conclusions Pain in elderlyPD patients is more severe,shows more diverse types,and significantly aftects the quality of life.Enhanced intervention is needed.

Objective To prospectively explore the impact of hypocalcemia on the prognostic value of intracerebral hemorrhage.Methods A total of 410 patients consecutively admitted within 12 hours after intracerebral hemorrhage onset were divided into 3 groups based on admission serum calcium:low serum calcium group,normal serum calcium group and high serum calcium group.Baseline characteristics of patients including age,gender,Glasgow coma score(GCS),hematoma volume,etc were collected and analyzed.A follow-up was performed after 6 months.Final outcome was assessed using Glasgow outcome scale(GOS)with a score＞3 regarded as favourable prognosis,a score≤3 as unfavourable prognosis.Results Patients with low serum calcium had lower GOS,bigger hematoma volume,higher rate of operation,higher re-bleeding rate,more unfavourable prognosis than did the other 2 serum calcium groups.Multivariable Logistic regression analysis showed that patients with low serum calcium had poorer prognosis than patients with normal serum calcium after adjusting for other potential confounders(Odds ratio:3.01,95％ confidence interval:1.06-6.12,P＜0.05).Conclusions Hypocalcemia is an independent risk factor for the prognosis of patients with intracerebral hemorrhage.

OBJECTIVE: To analyze the association between genetic polymorphisms of xenobiotic- metabolizing enzymes GSTM1, GSTT1, GSTP1 and susceptibility to laryngeal carcinoma from the Han people in Guangdong zone. METHOD: A case-control study was conducted involving 233 LSCC (laryngeal squamous cell carcinoma) patients and 102 healthy controls to investigate the association between polymorphisms of GSTM1, GSTT1, GSTP1 (Ile/Val) and LSCC from the Han people in Guangdong zone. All blood samples of the Han people from the Guangdong zone was analyzed with methods of PCR, ASA and the DNA sequencing technique with sequenator. We explored the association between polymorphisms and the clinical pathologic characteristics of LSCC. The data was processed with SPSS13.0. Odds Ratios (ORs) with 95% CI for relevancy intensity were calculated using binary logistic regression analysis. RESULT: The frequency of GSTM1(-) and GSTT1(-) genotype was higher in LSCC than that in healthy controls (OR = 2.61, 3.05, P < 0.01). There was synergic effect between GSTT1 (-) genotype and heavily smoking during carcinogenesis of LSCC (OR = 3.51, 95% CI 2.05-5.01; OR = 2.99, 95% CI 2.00-4.49). The frequency of GSTM1(-) and GSTT1(-) genotype was higher in LSCC whose family had carcinoma history. The frequency of advanced LSCC was higher in patients who were with GSTM1(-) and GSTT1 (-) genotype (P < 0.05). There was no difference of the frequency of GSTP1(I le/Val) genotype between and in healthy controls (P > 0.05). CONCLUSION There may be an association between the susceptibility to carcinoma and GSTT1(-), GSTM1(-) genotype. The GSTT1(-) polymorphism c gene cooperating with heavily smoking boost up the susceptibility of individual to laryngeal carcinoma. The GSTM1(-) polymorphism c may not cooperating with smoking during carcinogenesis of LSCC in the Han people in Guangdong zone. The morphisms of GSTT1 and GSTM1 gene may affect the carcino-genesis of LSCC in the Han people in Guangdong zone. There may be no association between the susceptibility to laryngeal carcinoma and the GSTP1(Ile/Val) type.
