Objective To investigate the incidence and risk factors of hallucination in patients with Parkinson’s disease (PD) by using a questionnaire. Methods Ninety-one patients with PD from outpatient and inpatient departments of Neurology and 38 healthy subjects were recruited. Mini-mental state examination (MMSE), unified Parkinson's disease rating scale-Ⅲ(UPDRS-Ⅲ), Hoehn-Yahr, interleukin 6 (IL-6) and C-reactive protein (CRP) were examined in all PD. According to the PPQ-B scores, the PD patients were divided into two groups:the hallucination group (PPQ-B≥1) and non-hallucination group (PPQ-B=0). Logistic regression model was used to explore the risk factors. Results Twen?ty-nine of 91 patients had hallucination and the incidence was 32%. Age and the levels of IL-6 and CRP were signifi?cantly higher in hallucination group than in non-hallucination group. Meanwhile, the duration of illness and MMSE were significantly higher in hallucination group than in non-hallucination group. Logistic regression revealed that the age and duration of illness were independent risk factors of hallucination and the Odds Ratios (OR) were 1.09 (95% CI:1.04~1.32, P<0.05) and 1.43 (95%CI:1.21~1.87, P<0.05), respectively. The risk of hallucination increased by 51%and 59%for each doubling of IL-6 and CRP levels in PD patients and the ORs were 1.51 (95%CI:1.13~2.11, P<0.05) and 1.59 (95%CI:1.07~2.66, P<0.05), respectively. Conclusions Controlling the levels of serum IL-6 and CRP plays an impor?tant role in delay or prevention of the hallucination of PD patients.

ObjectiveTo analyze the mental status of the patients with irritable bowel syndrome (IBS).MethodsSixty IBS patients were evaluated with Self Rating Anxiety Scale (SAS), Self Rating Depression Scale (SDS), Symptions Check List-90 (SCL-90) and self-edited scale.ResultsThe primary causes of mental disorder of IBS patients were the stress events and lacking knowledge for IBS; the average SAS scores of sixty IBS patients were 52.32±10.19, SDS scores were 54.90±11.70; the average scores of SAS and SDS in the groups of midlife and young people were significantly higher than that in the group of agedness ( P<0.05). The total scores of SAS and SDS were not significantly difference among the patients with different culture level and sex ( P>0.05); except the scores of crankiness and opposition, the average SCL-90 scores of the sixty IBS patients were significantly higher than the normal ( P<0.05).ConclusionIBS relates to mental status and stress, proper mental intervention can ease the symptom and improve the quality of the living.

To compare the effectiveness and safety of spinal versus general anesthesia for arthroplasty with respect to deep vein thrombosis(DVT),pulmonary embolism (PE) and epidural hematoma.Randomized controlled trials involving spinal and general anesthesia for arthroplasty were searched.Quality assessment were analyzed according to the Cochrane Collaboration's rule.A total of 12 trials involving 1023 participants met the inclusion criteria,Meta-analyses showed that spinal anesthesia may reduce the incidence of DVT or PE after arthroplagty without anticoagulant.There is no difference in the incidence of DVT and PE when anticoagulant is used.Whether anticoagulant was used or not,no epidural hematoma was observed after using the two anesthesia methods.

Objective To investigate the occupational risk awareness levels of higher vocational nursing students before and after the clinic practice.Methods Five-year higher vocational nursing students were investigated by filling out questionnaires before and after the clinic practice.Results Nursing students' occupational risk awareness improved after the clinic practice.They hoped to acquire knowledge about occupational risk and thought that the school was supposed to offer professional ethics courses and strengthen the occupational risk education.Conclusions The majority of nursing students knew the protective measures of occupational exposure in nursing.But there were also someone who did not know these.Relevant knowledge was in high demand.Therefore,schools and internship units should provide a variety of ways to reduce the risks during the internship of nursing students.

Objective To observe the different changes of macular microstructure in patients with large idiopathic macular hole (IMH) treated with vitrectomy combined with internal limiting membrane (ILM) transplantation or not.Methods Forty eyes in 40 consecutive patients with giant IMH (≥500 μm) were included in the study.Twenty eyes received vitrectomy with ILM transplantation (ILM transplantation group) and others with ILM peel off (ILM removal group).During the operation,a proper size of the ILM was removed and filled in the bottom of the macular hole.The age,duration of disease and the ocular laterality of the two groups of patients were not statistically significant (P＞0.05).Minimum resolution angle in logarithmic (logMAR) best corrected visual acuity (BCVA) and frequency domain optical coherence tomography (SD-OCT) scan were examined.There was no statistically significant difference in logMAR BCVA,average defect diameter of photoreceptor ellipsoid (IS/OS) and average defect diameter of external limiting membrane (ELM) between two groups (t=0.128,1.452,1.321;P＞0.05).The logMAR BCVA and SD-OCT were examined on 1,3,6,12 months postoperatively.Results On 1 month after the surgery,there was no statistically significant difference in logMAR BCVA,average defect diameter of IS/OS and average defect diameter of ELM between two groups (t=1.226,1.435,1.018;P＞0.05).On 3,6,12 months after the surgery,compared with ILM removal group,the logMAR BCVA (t=2.059,2.871,2.415) increased and the average defect diameter of IS/OS (t =2.070,2.110,2.121) and ELM (t =2.034,3.647,3.556) significantly reduced in ILM transplantation group (P＜0.05).On 1 month after the surgery,there was statistically significant difference in CRT between two groups (t=2.113,P＜0.05).On 3,6,12 months after the surgery,there was no statistically significant difference in CRT between two groups (t=0.428,0.847,0.849;P＞0.05).Conclusion Compared with vitrectomy combined with ILM peeling surgery,the diameter of IS/OS and ELM defect were significantly decreased after vitrectomy combined with ILM transplantation in the patients with large IMH.

Background The potential protective effect of ischemia postconditiomng for hypoxia has been determined in many tissues and organs.But its mechanism in retina is still lack.Objective The aim of this study was to investigate the protective effect of ischemia postconditioning on retinal ischemia reperfusion injury.Methods Thirty-six health male Wistar rats were randomized into the normal control group,sham group,ischemia reperfusion group and ischemic postconditioning group.Retinal ischemia reperfusion models were induced by elevating the intraocular pressure to 110 mmHg for 60 minutes,and then the ischemic postconditioning was performed right away,1 minute and 10 minutes after ischemia in the rats of the ischemic postconditioning Ⅰ,Ⅱ,Ⅲ group,respectively.Electroretinogram (ERG) was recorded in the rats 7 days after operation,and the rats were sacrificed by excessive anesthesia.Retinal specimens were prepared for the histopathological examination.The retinal thickness and the recovery rates of ERG a,b waves and oscillation potentials (OPs) were compared among the groups using ANOVA of SPSS software.Results One day after experiment,the structure of rat retinas was nearly normal.However,retinal edema and vacuolar degeneration were seen in the rats of the ischemia reperfusion group and ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups primarily in the inner plexiform layer (IPL),inner nuclear layer (INL).The retinal thickness values of the entire layer,IPL and INL were significantly higher in the ischemia reperfusion group and ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups compared with the normal control group (all at P＜0.05).Seven days after experiment,the retinas were thinner in the rats of the ischemia reperfusion group than those of the rats in the sham group,but the retinal thickness values in the ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups were significantly increased in comparison with the ischemia reperfusion group (all at P＜0.05).In addition,the recovery rates of ERG a,b,OPs amplitudes were significantly lower in the ischemia reperfusion group and ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups compared with the normal control group (all at P＜0.05).However,the recovery rates of ERG a,b,OPs amplitudes evidently elevated in the ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups in comparison with the ischemia reperfusion group (all at P＜0.05).Conclusions Ischemia postconditioning can protect the structure and function of retina from ischemia reperfusion injury.Ischemia postconditioning plays the maximal effect immediately to 1 minute after ischemia reperfusion injury in Wistar rat.

Objective : To examine the association between dietary patterns during pregnancy and gestational diabetes mellitus (GDM), so as to provide the evidence for guiding the establishment of healthy and balanced dietary patterns and reducing the prevalence of GDM. Methods: Pregnant women who underwent oral glucose tolerance tests in Hangzhou Obstetrics and Gynecological Hospital from 2020 to 2021 were enrolled, and their demographic information were collected using questionnaires. Pregnant women's diets during the past three months were collected using Food Frequency Questionnaires (FFQs), and dietary patterns were extracted using principal component analysis. In addition, the association between dietary patterns and risk of GDM was examined using a multivariable logistic regression model. Results: A total of 1 689 pregnant women were included, with a median age of 28.53 (interquartile range, 2.47) years and a median gestational age of 26.00 (interquartile range, 2.00) weeks. Five dietary patterns were identified according to pregnant women's types of diets, including meat-based diets, dessert-fruit-refined grain diets, plant-based diets, eggs-milk-nut diets and whole-grain diets, with a cumulative contribution rate of 58.76%. The prevalence of GDM was 24.57% (415 cases) among the study subjects. Multivariable logistic regression analysis showed that pregnant women with scores in the highest quartile (Q4) of the meat-based diets had an increased risk of GDM (OR=1.372, 95%CI: 1.043-2.055) relative to those with scores in the lowest quartile (Q1), and pregnant women with Q4 scores of the dessert-fruit-refined grain diets had an increased risk of GDM (OR=1.743, 95%CI: 1.397-2.432) relative to those with Q1 scores, while pregnant women with Q4 scores of the plant-based diets had a reduced risk of GDM (OR=0.382, 95%CI: 0.346-0.613) relative to those with Q1 scores. Conclusion A plant-based dietary pattern may reduce the risk of GDM, while meat-based and dessert-fruit-refined grain dietary patterns may increase the risk of GDM.

876 women with polycystic ovary syndrome (PCOS) were collected from Sep 2004 to Oct 2006. Among them 800 patients with polycystic ovary ultrasound image belonged to group A; the other 76 women without polyeystic ovary ultrasound image belonged to group B. As compared with group A, group B showed significantly higher hirsutism scores, serum testosterone, cholesterol, and lower density lipoprotein. Significantly higher prevalences of diabetes mellitus and hypertension appeared in the first degree relatives in group B than in group A.

Objective To study the association between three single nucleotide polymorphisms (SNP; rs2241766,rs1501299 and rs12495941) variants of the adiponectin gene (ADIPOQ) and polycystic ovary syndrome (PCOS) in PCOS family trios.Methods A total of 224 unrelated PCOS probands,their biological parents were recruited.Anthropometric variables such as waist circumference (WC),hip circumference (HC),height and weight were measured in all subjects during the first visit to the outpatient department.Body mass index (BMI) and waist-hip ratio (WHR) were calculated.Serum fasting glucose (FBG),fasting insulin (FINS),total cholesterol (TC),triglycerides (TG),low-density lipoprotein and highdensity lipoprotein cholesterol (HDL) levels were measured.PCOS patients were divided into two groups based on BMh group A (BMI＜25 kg/m2) and group B (BMI≥25 kg/m2).Parents of PCOS patients were accordingly categorized into group C,D (fathers) and group E,F (mothers).The transmission disequilibrium test (TDT) was used to analyze the association between three SNP of ADIPOQ and PCOS.Results (1) A significant positive association was detected between SNP rs1501299 and PCOS (x2=7.093,P=0.008).However we failed to find significant overtransmission of the other two SNP rs2241766 and rs12495941 from parents to PCOS offsprings (x2=1.620,P=0.203; x2=0.713,P=0.398).(2) Linkage disequilibrium (LD) was analyzed in the subjects,rs1501299 and rs2241766 were in weak LD (r2=0.063,D'=0.621).(3) The levels of WC,HC,WHR,testosterone,TG,HDL and FINS were significantly differences between obese and lean PCOS patients (P＜0.05).While in fathers we only found WC,HC,TC levels being statistically different (P＜ 0.05).Mothers of obese PCOS patients had increased levels of FINS compared with mothers of lean PCOS patients (P＜0.05).The genotype frequencies of the three SNP were not different in obese and lean PCOS patients and their parents (P＞0.05).Conclusions TDT confirms that SNP rs1501299 in the ADIPOQ is significantly associated with the risk of PCOS in the Chinese Han population.The three SNP of the ADIPOQ were not associated with the obesity of PCOS.
