Objective To perform an anatomical study on anterior approach to fractures of the pelvis and acetabulum in an attempt to testify feasibility of the approach.Methods Position and variation of anatomical structure of the hypogastric abdominal wall and pelvic cavity were observed in 10 cadaveric adults (20 sides).Based on the anatomical study,anterior approach to pelvic fractures (n =20)and acetabular fractures (n =15) were performed and clinical results were observed.Results Anterior pelvic incision revealed no splitting or exposure of the spermatic cord/round ligament of uterus.Vertical incision through the muscle layer of abdominal wall located at lateral rectus abdominis and medial initial segment of hypogastric arteries/veins.In clinical practice,the approach revealed the mean incision length of 10 cm (range,9-12 cm) and mean blood loss of (225.5 ± 30.5) ml (range,170-350 ml).No injuries to femoral nerve and sciatic nerve occurred and there was no deep vein thrombosis.Surgical incision healed primarily.Bone union were recorded at the 18-month follow-up (11-35 months).Conclusions Anterior pelvic approach stretches the operative field from pubic symphysis to anterior-lateral cacroiliac joint and quadrilateral surface,allowing full exposure of the fracture site.The approach has benefits of high safety,minor trauma,large exposure,and satisfactory results and hence deserves wide application in clinical settings.

Objective To determine the prevalence of rapid eye movement(REM)sleep behavior disorder(RBD)in patients with Parkinson' s disease(PD)and to investigate the risk factors of PD-RBD and its effect on the progress of PD. Methods Using the minimal diagnostic criteria of parasomnias described in the International Classification of Sleep Disorders-Revised(ICSD-R)to diagnose clinically probable RBD(cpRBD), patients were assessed by Unified Parkinson's Disease Rating Scale(UPDRS),MMSE, Montreal Cognitive Assessment(MoCA)at baseline and followed for 2.5 years. Results The frequency of cpRBD ranged from 35.6%(47/132)to 41.7%(55/132)during the study period. 11.4% (15/132)patients dropped out from the study. Lower MoCA score and type of onset are independent factors with cpRBD; Lower MoCA score(OR =0. 817 ,P =0. 004)is the risk factor while tremor(OR =0. 247 ,P =0. 020)is the protective factor. PD in patients with PD-RBD may progress more rapidly than non PD-RBD patients(UPDRS Ⅲ change from baseline 9. 86 ± 4. 96 vs 6. 76 ± 4. 26, t = 2. 909, P = 0. 005; H-Y change from baseline 0. 77 ± 0. 54 vs 0. 33 ± 0. 49, t = 3. 664, P = 0. 000). Conclusion RBD may be a symptom predictive for rapid PD progression, declining cognition and psychosis.

Objective To study the incidence of rapid eye movement sleep behavior disorder (RBD) and its impact on the clinical manifestations of patients with Parkinson' s disease (PD). Methods One hundred and twenty-four PD patients were included into this study and each of them was given the non motor symptoms questionnaire (NMSquest) to investigate the incidence of RBD. The PD patients were then divided into the RBD group and non RBD group, according to their answers to the NMSquest. Then the clinical differences were investigated between PD patients with and without RBD on the aspects of demographic characters, Hoehn-Yahr (H-Y) stage, the scores of Unified Parkinson Disease Rating Scale (UPDRS) sub-items, the incidence of non motor symptoms, and the dysfunctions of non motor systems (cognitive impairment, anxiety, depression and sleep disorders ). The evaluation tools of non motor functions include Mini Mental State Exam ( MMSE), Hamilton Depression Scale (HAMD), Parkins' s Disease Sleep Scale (PDSS) and Epworth Sleepiness Scale (ESS). Results ( 1 ) 62.9% (78/124) of the PD patients have been experiencing RBD. (2) The course of the disease in RBD group ( 3.8 ± 2.8 ) was significantly shorter than non RBD group (5.0 ± 2.5, t = - 1. 972, P = 0. 048 ) while the sex, age, onset age and the mode of onset, Levodopa dose equivalents (LDE) and the kinds of medicines showed no difference between the two groups. (3) H-Y stage, the scores of UPDRS sub-items and the incidence of motor complications showed no difference between RBD and non RBD group. (4) Most of the non motor symptoms, including the gastrointestinal dysfunctions, autonomic dysfunctions, mood disorders and sleep disturbances, occurred much frequently in RBD group, however, the scores of MMSE, HAMD, HAMA,PDSS and ESS showed no difference between the RBD and non RBD group. Conclusion RBD commonly occurred in PD patients, and PD patients with RBD have a tendency to suffer from dysfunction of non motor systems.

Objective To derive a questionnaire to assess the risk of developing motor complications through a 3-year prospective investigation on 71 patients of Parkinson' s disease (PD) in the out clinic at our hospital.Methods Three years after the first assessment,71 PD out patients were reassessed using various scales,including Unified Parkinson Disease Rating Scale,Hoehn-Yahr grade,Mini Mental State Exam,Hamilton Depression Scale and Hamilton Anxiety Scale.Results The incidence of motor complications was 43.6％ (31/71).Logistic regression analysis showed that the prognostic factors for motor fluctuation were age of onset ≤ 54 (OR =6.4,95％ CI 1.7-24.5,P =0.006),the occurrence of swallowing difficulty (OR =3.8,95 ％ CI 1.0-14.1,P =0.04) and depression (OR =4.0,95 ％ CI 1.1-13.7,P =0.03),and the prognostic factors for dyskinesia were age of onset ≤54 (OR =48.5,95％ CI 1.9-121.0,P:0.02),the occurrence of falling (OR =64.1,95％ CI 2.9-142.2,P =0.008) and the daily levodopa dosage ＞ 600 mg(OR =17.5,95％ CI 1.1-276.2,P =0.04).Based on the regression model,the assessment questionnaire for motor complicationsincludes the followings:the questionnaire for motor fluctuations:the age of onset ≤54,2 points; the occurrence of swallowing difficulty,1 point; the occurrence of depression,1 point; the questionnaire for dyskinesia:the onset age ≤54,2 points; the occurrence of falling,3 points; daily levodopa dosage ＞ 600 mg,2 points.In all patients in this study,21.7％ (10/46) was asscssed to a total scorc of 0-1 which is associated with a low risk of motor fluctuation,8/16 had a score of 2 which is associated with intermediate risk and 8/9 got a score of 3-4 associated high risk; 10.2％ (5/49) had a score of 0-2,a low risk of dyskinesia,4/13 had a score of 3-4,a intermediate risk and 7/9 got a score of 5-7 which is associated with a high risk.Conclusions Age onset ≤54,the occurrence of swallowing difficulty,falling and depression,daily levodopa dosage ＞ 600 mg were considered to be the prognostic factors of motor complications in PD.The questionnaire may help to stratify PD patients into low-risk,medium-risk and high-risk groups for motor complications and the higher the score in the questionnaire is related to the higher risk of motor complications.

Objective To identify primary gout biomarkers. Methods Isobaric tags for relative and absolute quantitation (iTRAQ) technique combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to screen differentially expressed proteins, and to identify potential biomarkers by analysis of the biological process, cellular components, molecular functions, KEGG pathways and protein-protein interactions. Difference between two groups were measured byt test. Results We identified 95 differentially expressed proteins (50 up-regulated proteins and 45 down-regulated proteins, respectively), and 20 significant KEGG pathways. Among them, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), α-enolase (ENOA), phosphoglycerate kinase (PGK1), glucose-6-phosphate isomerase (G6PI) and moesin might play a role in the pathogenesis of primary gout. Conclusion iTRAQ technology can detect differentially expressed proteins from proteome, provides a strong theoretical basis for the study of biomarkers and evidence for the mechanisms in primary gout. However, further studies are needed.

Objective To observe progression of motor symptoms and occurrence of motor complications in parkinsonian patients and investigate the rate of progression of motor symptoms and risk factors of motor complications.Methods One hundred and thirty patients diagnosed with PD in 2007 in Department of Neurology,Xinhua Hospital were followed up for 3 years.The Unified Parkinson' s Disease Rating Scale (UPDRS) and H-Y staging were used to assess and follow up motor symptoms and occurrence of motor complications,and analyze the rate of progression of motor symptoms and risk factors of motor complications with statistics.Results ( 1 ) Mean annual growth in H-Y staging was 2.5％,and UPDRS motor scores was 3.1％ ; the incidence of dysphagia at endpoint in patients was increased by 23.0％ compared with baseline; incidence of falls was increased by 16.7％;(2)Daily levodopa dose at endpoint ( OR =1.004,95％ CI 1.001—1.006,P =0.008 ) was independent risk factors with dyskinesia; While duration ( OR =1.637,95％ CI 1.083—2.473,P =0.019 ),levodopa treatment duration ( OR =0.698,95％ CI 0.494—0.987,P =0.042 ),daily levodopa dose at haseline ( OR =1.005,95％ CI 1.001—1.010,P =0.016) and at endpoint ( OR =1.014,95 ％ CI 1.001 —1.027,P =0.032 ) were risk factors with motor fluctuations.Conclusions As the disease progresses,motor function in parkinsonian patients gradually worsens,the incidence of swallowing difficulty and of falls is increased,and the incidence of motor complications is increased.The total exposure to levodopa in parkinsonian patients is predictor for motor complications.

The clinical characteristics and gene variations of a family with mitochondrial myopathy and ataxia caused by MSTO1 gene mutation who visited Xiangya Hospital of Central South University in October 2019 were retrospectively analyzed.The proband was an 11-year-old female, who was found to have delayed motor and language development and dysarthria at the age of 1 year and 6 months.The 9-year-old younger brother of the proband had similar symptoms at the age of 1 year and 3 months.Both the proband and her younger brother had muscle weakness and ataxia.Their head magnetic resonance imaging showed cerebellar atrophy, and their electromyography showed neuroge-nic changes.Genetic testing revealed compound heterozygous mutations in MSTO1: c.1259delG; p.G420VfsX2 and c.571 C > T; p.R191X, which were inherited from their parents, respectively.The same site mutations were found in the younger brother.After 2 weeks of " cocktail therapy" , the symptoms of the children were alleviated, and their language and movement improved.

Objective: To understand prevalence and trend of drinking behavior among middle school students in Quzhou during 2012 to 2022, and to provide a basis for formulating scientific and effective intervention measures for adolescent drinking. Methods: By using stratified cluster sampling method, a questionnaire survey using Zhejiang adolescent health related behavior questionnaire was conducted anonymously in selected classes in May 2012, 2017 and 2022, respectively. Changes of drinking behavior of middle school students in different years were analyzed. Results: The prevalence of ever drinking, current drinking and drunkenness among middle school students in Quzhou decreased from 58.05%, 22.70% and 21.25% in 2012 to 41.83%, 15.35% and 11.54% in 2022, respectively ( χ 2 trend =82.69, 30.00，58.24, P <0.01). In the past 30 days, 66.67% of students reported drinking 1-2 days, the proportion of drinking for 3-5 days increased from 16.36% in 2012 to 26.19% in 2022, the proportion of drinking for 6-19 days decreased from 13.03% in 2012 to 3.40% in 2022. The proportion of buying alcohol increased from 22.12% in 2012 to 35.03% in 2022. The results of the three surveys showed that, now drinking rates, drinking rates, Male students (27.88%，23.96%，18.75%；24.69%，17.44%，13.75%) was higher than the girls (17.60%，17.25%，11.31%；17.87%，10.61%，8.91%)， non ordinary high schools (33.96%，34.69%，22.77%；33.65%，23.91%，19.49%) were higher than ordinary high schools (25.82%，18.80%， 12.62 %；25.82%，17.35%，9.94%) and junior middle school (16.53%，15.83%，12.22%；13.93%，8.47%，7.35%). Conclusion Progress in adolescent drinking control is being made in Quzhou, with the prevalence of ever drinking, current drinking and drunkenness significantly decreased. It is necessary to strengthen the control of drinking behavior among middle school students from the aspects of school, family and society, especially for boys and students in non ordinary high school students.
