The plant AT-rich sequence and zinc-binding protein (PLATZ) family is composed of plant-specific zinc finger-like transcription factors, which play important roles in plant growth, development, and stress tolerance. In this study, to gain a better understanding of the PLATZ gene in C. sinensis and elucidate its response under drought and high temperature conditions, the PLATZ gene family of the C. sinensis cultivar 'Tieguanyin' was systematically identified, and a total of 12 CsPLATZ family members were identified. Expasy online and other bioinformatics tools were used to analyze the members of the PLATZ gene family in terms of protein physicochemical properties, phylogenetic relationships, cis-acting elements, gene structures, and intra- and inter-species collinearity. The results of phylogenetic analysis classified the CsPLATZ family members into 2 subfamilies. The conserved domains and gene structures of PLATZ family members within the same subfamily had a high degree of consistency, whereas a certain degree of diversity was observed among the subfamilies. Twelve PLATZ genes were unevenly distributed across 7 chromosomes of C. sinensis and the promoter regions of these genes had multiple cis-acting elements related to hormone and stress responses. The collinearity analysis showed that there were 4 pairs of duplication events in the CsPLATZ gene family, all of which were segmental duplications. Based on this gene family, C. sinensis had a closer evolutionary relationship with A. thaliana than with O. sativa. The transcriptome analysis showed that the expression levels of CsPLATZ family members varied in different tissue samples of C. sinensis. 6 genes (CsPLATZ-1, CsPLATZ-2, CsPLATZ-3, CsPLATZ-4, CsPLATZ-6, and CsPLATZ-8) with high expression in shoots, young leaves, and roots were selected for high temperature and drought stress treatments, and their expression was quantified by qRT-PCR. The results indicated that the six genes might play important roles in the response to drought stress. In addition, CsPLATZ-2 and CsPLATZ-8 might have important functions in the response to high temperature stress. The results of this study will contribute to a better understanding of the biological functions of PLATZ genes and their possible roles in the growth, development, and stress responses of C. sinensis.

Objective: To explore sex differences in 3D T1texture features in the progression of Alzheimer's disease (AD) and to predict the diagnosis of AD patients of different sex． Methods: Seventy-seven AD patients (34 males and 42 females) ，74 amnestic mild cognitive impairment ( aMCI) patients ( 35 males and 39 females) and 75 healthy controls (HC) (35 males and 40 females) were recruited and high-resolution 3-dimensional T1 structural images were collected． Brain regions closely related to AD brain damage were selected as regions of interest ( ROIs) ，texture feature extraction and feature screening were performed．Analyses were performed by sex，and the support vector machine (SVM) was used for classification and prediction. Results : In the AD vs HC，AD vs aMCI and aMCI VS HC groups by different sex，we obtained some brain regions with relatively high recognition index in different subgroups，and found that there were significant differences between female patients and male patients with high recognition index，and the recognition index of female patients ( area under the curve，accuracy，sensitivity and specificity were generally higher than that of male． Conclusion There are significant sex differences in texture features in AD process，and the classification and prediction ability of texture features in female patients is better， suggesting the importance of sex differences in AD research．This study provides some reliable biomarkers for early sex-specific identification of AD，which may be helpful for the early diagnosis and treatment of AD in the future.

【Objective】 To evaluate the efficacy and weight of sellar floor repair techniques such as different dura suture, bone reconstruction, and pedicled nasoseptal flap (PNSF) on the skull base reconstruction of medium and high flow cerebrospinal fluid leakage during endonasal endoscopic pituitary adenoma surgery. 【Methods】 We collected the data of Grade 2-3 cerebrospinal fluid leakage (Kelly grade) during endonasal endoscopic pituitary adenoma resection in our hospital from January 2015 to April 2021. Multiple reconstruction techniques such as dura suture, bone reconstruction and PNSF, and related factors such as age, sex, body mass index (BMI), diabetes, tumor size and diameter of diaphragmatic defect were recorded and introduced to multivariate regression to analyze the effects of the above factors on the duration of postoperative cerebrospinal fluid rhinorrhea and bed rest time, with a special focus on the weight priority of dura suture, bone reconstruction, and PNSF. 【Results】 A total of 281 patients were included, with the average age of (47±12.6) years, males accounting for 52.6%. There were 93 cases of PNSF, 268 cases of bone reconstruction, 109 cases of dura anchor suture, 50 cases of patch suture, and 122 cases without suture. The results of multivariate analysis indicated that the application of PNSF, bone reconstruction, and dura suture significantly reduced postoperative rhinorrhea time [reduced by 18.524, 35.876, and 16.983/19.791 (anchor suture/patch suture) hours, respectively; all P<0.001] and bed time [reduced by 16.797, 58.233, and 18.063/21.604 (anchor suture/patch suture) hours, respectively; all P<0.001], and there was no significant difference between anchor suture and patch suture. The weight of the standardized coefficient in reducing postoperative rhinorrhea time was dura suture>PNSF>bone reconstruction [Standard β=0.211/0.207 (anchor suture/patch suture)>0.200>0.165]. The weight of reducing bed time was bone reconstruction >dura suture > PNSF [Standard β=0.239>0.206/0.210 (anchor suture/patch suture) >0.164]. After stabilizing the learning curve in 25-30 cases, the average time for bone reconstruction was (3.9±0.4) minutes. After stabilizing learning curve in 30-40 cases, the dura suture technique took an average of (3.7±0.3) minutes per stitch, (3.7±1.0) stitches per case, and (13.6±2.7) minutes of total time consumption per case. 【Conclusion】 Dural anchoring and patching suture can both effectively shorten the duration of cerebrospinal fluid rhinorrhea and bed rest time. Bone reconstruction significantly improves the stability of reconstruction, especially in prompting patients’ early disengagement of bed rest. Moreover, the learning curves of the above two methods are economical and reasonable, and their weight is close to or even exceeds that of PNSF. Therefore, they can be an effective supplement or even substitute for PNSF.

【Objective】 To introduce the repair application in medium-flow cerebrospinal fluid leakage during transsphenoidal pituitary tumor resection by using autologous material from the surgical site in situ， combined with dural suture and bone-mucosa embedding technique， and evaluate its effect. 【Methods】 We conducted a retrospective case analysis of medium-flow cerebrospinal fluid leakage during endoscopic transsphenoidal approach pituitary tumor resection in our hospital from September 2016 to March 2020. All the collected cases were divided into two groups. In situ material harvest group： dural suture + in situ bone-mucosa embedding， avoiding additional trauma to the thigh and nasal cavity， referred to as in situ group. Traditional multi-layer reconstruction group： fat + fascia lata + pedicled nasoseptal flap （PNSF）， referred to as traditional group. The important indexes related to repair were compared and analyzed between the two groups. 【Results】 The in situ group and the traditional group consisted of 108 and 63 cases， respectively. The baseline data of the two groups were comparable. For the incidence of postoperative cerebrospinal fluid leakage ［（1/108， 0.9%） vs. （1/63， 1.6%）， P>0.05］ and intracranial infection rate ［（2/108， 1.9%） vs. （2/63， 3.2%）， P>0.05］， no statistical difference was shown between the groups. While compared with that in the traditional group， the mean postoperative bed stay time ［（3.7±1.6） vs. （4.4±1.5） days， P<0.001］ and the mean postoperative hospital stay ［（5.8±1.8） vs. （6.5±1.7） days， P<0.001］ of the in situ group were significantly shorter. The in situ group had significantly lower incidences of postoperative olfactory disturbance ［（0/108， 0%） vs. （3/63， 4.8%）， P<0.05］ and nasal discomfort ［（3/108， 2.8%） vs. （7/63， 11.1%）， P<0.05］. Follow-up imaging and endoscopic examination showed that the reconstructed structure of the in situ group was stable， and there was no delayed cerebrospinal fluid leakage. 【Conclusion】 This technique showed a reliable effect in repairing medium-flow leaks during transsphenoidal pituitary tumor resection by restoring the anatomical structure while avoiding the additional trauma. It is beneficial to shortening bed stay and hospitalization time and improving the subjective experience of patients， thus having a great value in clinical application.

Objective: To discuss the prevalence and influential factors of stroke among population in Jiangxi Province. Methods: Four cities in urban areas and four counties in rural areas were selected firstly, in which two districts or townships were selected; and then three communities or villages were chosen from each district and township, respectively, using the simple random sampling (SRS) method. Finally 15 269 subjects aging 15 years old or above, living in Jiangxi Province ≥6 months were randomly selected to participate in this survey from November 2013 to August 2014. Information of population characteristics, life behavior way, individual disease history were collected through questionnaire survey, and height, weight, waist circumference, blood pressure, body fat rate, visceral fat index and so on were measured by instruments. Risk factors of stroke prevalence were analyzed by the unconditioned logistic regression analysis. Results: A total of 15 269 participants (6 267 males) from 15 364 eligible participants were included in the statistical analysis. Out of which, 7 793 participants came from urban areas, and their average age was (53.04±17.91) years old. In this study, 226 stroke patients (117 males) were found among15 269 participants, including 122 urban participants and 104 rural participants, whose average age was (67.76±9.74) years old. The prevalence of stroke was 1 480.12/100 000 in 2014, which was separately 1 866.92/100 000 and 1 210.84/100 000 among males and females. The prevalence of people aging (45-49) years old was 413.79/100 000 (6/1 450) , while which among people aging 75 years old and above was 3 311.62/100 000 (61/1 842) . The prevalence of stroke among residents in Jiangxi presented an uprising tendency with age increasing (linear-by-linear association χ²=62.23, P<0.01). The research showed that when other influencing factors including gender, BMI, waist circumference, pulse-pressure difference, VAI, and sleeping time in non-working days were controlled, hypertensive patients had a higher risk of stroke than people without hypertension (OR=6.88, 95%CI: 4.90-9.67), drinkers had a higher risk of stroke than non-drinkers (OR=1.56, 95%CI: 1.17-2.08), compared with people <65 years old, people aged 65-74 years old and ≥75 years old had a higher risk of stroke, the value of OR (95%CI) were 1.88 (1.36-2.59) and 1.97 (1.39-2.80), respectively, compared with people with normal body fat percentage, people whose body fat percentage on high side and people who with high body fat percentage had a higher risk of stroke, the value of OR (95%CI) were 1.71 (1.18-2.48) and 1.74 (1.18-2.56), respectively, people with sleep time >8 h had a higher risk of stroke than those with sleep time of 6-8 h. Conclusion There was a high stroke prevalence among residents in Jiangxi province. Hypertension, drinking, age, BFP and sleep duration were associated with stroke prevalence. Corresponding measures for high-risk population and risk factors should be strengthened to prevent and control the stroke.

Objective This study aims to investigate the effect of rehabilitation skills training on suicide and relapse prevention of patients with depression.Methods Eighty patients were randomly divided into two groups.One group accepted depression rehabilitation skills training and the other group accepted general health education for 4 weeks.Both groups were followed up by 12 months,and the number of relapse and suicide and the score of Health-related quality of life made by Word Health Organization (WHOQOL-BREF) were recorded.Results The rate of relapse (10.0％ vs.42.5％) and hospitalization (5.0％ vs.20.0％) were lower in skills training group than in control group (P＜0.05).Rate of seeking help of suicide was higher in skills training group than in control group (25.5％ vs.7.5％) (P＜0.05).The suicide mortality was insignificantly different between two groups (0.0％ vs.2.5％) (P＞0.05).The scores of WHOQOL-BREF were significantly higher in skills training group than in control group in follow-up (P＜0.05).Conclusions Rehabilitation skills training program can not only reduce the rate of relapse and suicide but also improve the quality of life of patients with depression.

Objective To observe microstructural changes of white matter in Alzheimer's disease (AD),and to find out the relationship between white matters lesion and declined cognition.Methods Twenty-four AD patients and 24 controls with normal cognition performed diffusion tensor imaging MR scan.Tract-based spatial statistical analysis (TBSS) was used to investigate microstructural change of white matter,and then its correlation with Mini-Mental State Examination (MMSE) scores was analyzed.Results Fractional anisotropy (FA) values were decreased in corpus callosum,fornix,left corticospinal tract,bilateral cerebral peduncle,superior cerebellar peduncle,internal capsule,corona radiata,posterior thalamic radiation,sagittal stratum including inferior longitidinal fasciculus and inferior fronto-occipital fasciculus,external capsule,cingulate gyrns,hippocampus,superior longitudinal fasciculus and uncinate fasciculus,while mean diffusivity (MD) values were increased in fornix,left hippocampus,bilateral internal capsule,corona radiata,posterior thalamic radiation,sagittal stratum including inferior longitidinal fasciculus and inferior fronto-occipital fasciculus,external capsule,cingulate gyrus,superior longitudinal fasciculus,superior fronto-occipital fasciculus and uncinate fasciculus (all P ＜ 0.05,threshold-free cluster enhancement corrected).MMSE scores had a positive correlation with decreased FA values of left sagittal stratum (r =0.535,P =0.007) and negative correlations with increased MD values of left sagittal stratum (r =-0.427,P =0.037),left superior longitudinal fasciculus (r =-0.424,P =0.039) and left uncinate fasciculus (r =-0.505,P =0.012).Conclusions There exist widespread white matter lesions in AD with impairment of white matter connections of intra-and inter-hemispheres.Impaired white matters in left hemisphere may have close relationships with cognition decline.

In this study, we analyzed two cases of pure cerebral fat embolism and reviewed related literatures to explore the pathogenesis, clinical manifestations, diagnosis and treatment of cerebral fat embolism, improve the treatment efficiency and reduce the misdiagnosis rate. In our cases, patients fully returned to consciousness at the different times with good prognosis, normal vital signs and without obvious sequelae. For patients with the limb fractures, who developed coma without chest distress, dyspnea or other pulmonary symptoms 12 or 24 h post injury, cerebral fat embolism should be highly suspected, except for those with intracranial lesions, such as delayed traumatic intracerebral hemorrhage, etc. The early diagnosis and comprehensive treatment can improve prognosis.
