BACKGROUND: Linxian County of China is one of the areas with the highest incidence of esophageal cancer and gastric cardia cancer in the world, and nutrition-deficiency is widely existing in local people. In recent years, many researches around the world revealed that the cause of Parkinson disease (PD) is related to factors of gene, age, environment, diet, nutrition and smoking. More and more studies confirmed that primary hypertension may be in relation to vascular Parkinsonism (VP) and long-term hypertension was apt to VP.OBJECTIVE: To investigate the relationship between hypertension and clinical probable Parkinson disease (PPD) in nutrition-deficient population of Linxian County and provide a theoretical basis for early prevention and treatment of PD.DESIGN: Cross-sectional study.PARTICIPANTS: A total of 4 335 subjects aged over 55 years were selected. These subjects have taken part in the nutritional intervention study of Linxian County and first entered in the cohort study in 1985. They were enrolled in the nutritional intervention study in Linxian County in 1985.METHODS: A prospective cohort study was conducted. ①Case screening: PD questionnaire (used in American Gebai County) combined with general neurological examination were adopted. ②The diagnosis of PD: Clinical diagnostic criteria of UK Parkinson Disease Society Brain Bank were taken as the criteria for screening PD. Further evaluations were undertaken for clinical PPD and clinical possible PD on subjects who had PD symptoms.The diagnostic criteria of clinical PPD: Subjects were diagnosed as having clinical PPD if they presented any two of the following two cardinal features (resting tremor, hypermyotonia, bradykinesia and impairment of postural reflexes) or presented any one of the following features (resting tremor, hypermyotonia and bradykinesia). Diagnostic criteria of clinical possible PD: Subjects were diagnosed as having clinical possible PD when presented any one of the following four cardinal features (resting tremor, hypermyotonia, bradykinesia, and impairment of postural reflexes).③Definition of hypertension: Hypertension was defined as the systolic blood pressure (SBP) ≥ 140 mm Hg or the diastolic blood pressure (DBP) ≥ 90 mm Hg. Data were processed with linear trend test and nonconditional logistic regression.MAIN OUTCOME MEASURES: Status of final diagnoses on patients and relationship between hypertension and clinical PPD.RESULTS: A total of 4 335 subjects including 2 008 males (46.32%)and 2 327 females (53.68%) participated in the screening of PD.①Results of final diagnosis on patients: Among all the 4 459 survival participants,46 subjects were diagnosed as having PD, 118 as having clinical PPD and 78 as having clinical possible PD. After excluding patients with PD or clinical possible PD, only 118 patients were diagnosed as having clinical PPD. These patients and 4 217 normal controls were analyzed and a total of 2 035 patients had hypertension. ②There were statistical correlation between hypertension and clinical PPD, RR was 1.648 (1.147-2.638), which was 1.668 (1.145-2.432) after being adjusted by possible confounding factors including age, gender, smoking, drinking and so on, the association mentioned above still existed (χ2=7.463,P=0.006). Analysis of gender showed statistically significant differences between female patients with hypertension and clinical PPD(χ2=9.669 P=0.002), and RR before adjust ment was 2.347 (1.347-4.091), which was 2.346 (1.327-4.150) after being adjusted and correlation still existed. While there were no statistical corre lations between male patients with hypertension and clinical PPD (χ2 =0.697 ,P=0.404)but there was also an ascending trend in RR value. ③ With the blood pressure increasing, the RR value correspondingly in creased with the linear trend test (χ2=11.325 ,P=0.003). And there was sta tistical significance in raw and adjusted RR value of hypertension with the BP ≥ 140/90 mm Hg. Respective statistics of SBP and DBP showed a dose-response relationship between SBP and clinical PPD; When the SBP ≥ 140 mm Hg, there were statistical significances in values of raw RR or adjusted RR of hypertension (χ2=8.007 ,P=0.018). While there were no sta tistical significances in RR values before and after adjustment of DBP (χ2 =2.569,P=0.227). CONCLUSION: Hypertension is one of the risk factors of clinical PPD in female residents older than 55 and the incidence of getting clinical PPD is increased with the heightening of BP.

Objective To study the effect and mechanism of increase in radio sensitivity of kidney cancer cells(GRC-1) induced by ?-elemenen in vitro. Methods GRC-1 cells were divided into 3 groups, blank group (added with 2 mL culture medium), emulsion group (added with 2 mL blank emulsion culture medium) and drug group (added with 2 mL 50 mg?L -1 ?-elemenen culture medium). After been cultivated for 24 hours, the cells were irradiated using 6MeV X-linear accelerator in different doses at the rate of 400cGy per minute. Number of cell clones was counted, and radiation-survival curve of GRC-1 cells was drawn. Flow cytometry (FCM) was used to measure cell cycle and apoptosis. Cells of climbing flake were dyed by immunocytochemical method, the gene expression of bcl-2 and PCNA was measured by imaging system. Results The cell cycle showed that the G 2M blocking caused by 50 mg?L -1 ?-elemenen was enhanced with time increase. It reached peak at 24 hours. FCM showed that the level of apoptosis increased with increase in drug dose and action time. The gene expression of bcl-2 was decreased by 20% in drug group than that in blank group, but there was no expression of PCNA in the two groups. Conclusion The radiosensitivity of GRC-1 cells can be enhanced by ?-elemenen. The mechanism of effect may be associated with the cell cycle blocking, inducing cell apoptosis and down-regulating expression of bcl-2 gene.

Objective Preoperative autologous blood donation ( PABD) may reduce the need for allogeneic blood , but it may also cause a short massive blood loss in pregnant women , and its fetal and maternal safety has to be adequately assessed .This study was to evaluate the feasibility and safety of PABD for pregnant women and their fetuses . Methods A prospective observational study was conducted among the women who met the inclusion criteria and gave birth in Nanjing Drum Tower Hospital between January and December 2013 .According to the clinical validation of risk stratification criteria for peripartum hemorrhage of California 2013 , the ca-ses were classified into a low-, a medium-, and a high-risk group.Data on blood donation procedures , obstetric outcomes, and blood transfusions were collected after delivery for analysis . Results Totally, 92 pregnant women accomplished 115 blood donations .The median volumes of the donated blood were 300, 300, and 400 mL in the low-, medium-, and high-risk groups, respectively ( P>0.001).There were no significant changes in HR , SBP and SpO2 during the blood donation procedures (P>0.05) except for the fall of diastolic blood pressure by an average of 3.4 mmHg (P<0.05) at 5 minutes after blood collection, which was restored to normal later.Non-reassuring fetal heart rate patterns were not found in any of the cases .The levels of HB and HCT were remarkably lower af-ter donation than before it (P<0.05) but restored to normal before delivery in the PABD cases who donated once only (P>0.05), which were similar to those in the cases who donated twice , with no significant differences before and after the donation (P>0.05). Homologous blood transfusion was performed for 5 cases (17.9%) in the high-risk group, with the volume of blood loss >2000 mL in all the cases.All the newborns survived without asphyxia and there was no perinatal death . Conclusion PABD can provide timely autologous whole blood donation for pregnant women .Under strict management , PABD is feasible and safe for pregnant patients who are at a high risk for massive blood loss during delivery or have a rare type of blood no readily available .

OBJECTIVE: To investigate the character of upper airway and to offer the reference for clinical treatment through observing the upper airway caliber and its corresponding pharyngeal wall of OSAHS patients by magnetic resonance imaging (MRI). METHOD: The upper airway of 33 obstructive sleep apnea hypopnea syndrome (OSAHS) patients diagnosed by PSG were analyzed and compared by MRI. The cross-sectional area of the upper airway and thickness of lateral parapharyngeal wall were calculated. The cross-sectional area of the upper airway and thickness of lateral and posterior pharyngeal wall were also measured in 20 nonsnoring age-matched normal subjects selected as the control group. RESULT: The cross-sectional areas of upper airway of OSAHS patients were smaller than that of the control. The Thickness of posterior pharyngeal wall and lateral pharyngeal wall of the retropalatal region, retroglossal region and epiglottal region were thicker in patients group than that of the control. The thickness and length of the palate in patients group were larger than that of the control. The cross-sectional areas of retropalatal region of OSAHS patients had negative correlation with apnea hypopnea index (AHI). There was also negative correlation between the retroglossal region cross-sectional area and the neck circumference. CONCLUSION Measurement of upper airway with MRI could observe the change of pharynx cross-sectional area and had reference value in guiding the clinical diagnosis and treatment.

Objective:To compare the application of 13N-NH 3, 11C-methionine (MET) and 18F-fluorodeoxyglucose (FDG) PET/CT imaging in the diagnosis and evaluation of suspected cerebral glioma. Methods:From September 2010 to December 2017, ninety patients (54 males, 36 females; age: (40.0±14.0) years) in the First Affiliated Hospital of Sun Yat-sen University with suspected glioma based on clinical diagnosis, who underwent 13N-NH 3, 11C-MET and 18F-FDG PET/CT imaging, were prospectively enrolled in the study. All patients were confirmed by histology or clinical and radiological follow-up. Images were interpreted by visual evaluation (higher radioactive uptake in lesions than that in the contralateral normal brain parenchyma was considered as positive (+ ), equal/lower were considered as negative (-)) and semi-quantitative analysis (the maximum standardized uptake value (SUV) of lesion (L) to the mean SUV of normal white matter (WM) (L/WM ratio)). Receiver operating characteristic (ROC) curve analysis was used and the area under curves (AUCs) were calculated and compared. The diagnostic efficacies of 3 imaging methods and the combination for diagnosing gliomas and the abilities to differentiating high-grade gliomas (HGG) and low-grade gliomas (LGG) were compared. Results:In 90 patients, 30 HGG, 27 LGG, 10 non-glioma brain tumors and 23 non-neoplastic lesions (NNL) were diagnosed. On visual evaluation, the sensitivities for differentiating tumors from NNL were 62.7%(42/67), 94.0%(63/67) and 35.8% (24/67) for 13N-NH 3, 11C-MET and 18F-FDG PET/CT respectively, while the specificities were 95.7%(22/23), 56.5% (13/23) and 65.2% (15/23), and the accuracies were 71.1%(64/90), 84.4%(76/90) and 43.3% (39/90). Taking the metabolic patterns of + /+ /+ , + /+ /- and + /-/- ( 11C-MET/ 13N-NH 3/ 18F-FDG) as the diagnosis standard of tumor lesions, the specificity and accuracy of the combined method increased to 73.9%(17/23) and 88.9%(80/90) with the sensitivity remaining the same (94.0%, 63/67). ROC curve analysis (L/WM) showed that the sensitivity, specificity and AUC were 64.2%(43/67), 100%(23/23) and 0.819 for 13N-NH 3 PET/CT, and 89.6%(60/67), 69.6%(16/23) and 0.840 for 11C-MET PET/CT ( z=-0.316, P>0.05). The accuracy for differentiating high and low grade glioma were 86.0% (49/57), 87.7%(50/57) and 93.0%(53/57) for 13N-NH 3, 11C-MET and 18F-FDG PET/CT, with the AUC of 0.896, 0.928 and 0.964, respectively ( z values: -0.554 to 1.334, all P>0.05). Conclusions:13N-NH 3 PET/CT imaging has remarkably high specificity but low sensitivity for the differentiation of brain tumors from NNL. 11C-MET PET/CT imaging was found to be highly useful for detection of brain tumors. However, like 18F-FDG, high MET uptake is frequently observed in some NNL. 13N-NH 3, 11C-MET and 18F-FDG PET/CT imaging all appear to be valuable for evaluating the histological grade of gliomas, and the combination of them is more useful for the accurate diagnosis of glioma.

Objective:To observe the effects of Huatan Quyu Decoction on the protein expressions of β-catenin and GSK-3 β and the expression of anticardiolipin antibody and β-amyloid protein related to cognitive function in rats with vascular dementia based on Wnt/β-catenin signal pathway.Methods:A total of 96 male SD rats were divided into blank group, model group, Donepezil hydrochloride group and Huatan Quyu Decoction low-, midium-, high-dosage group according to random number table method, with 16 rats in each group. Except for the blank group, the rat model of vascular dementia was prepared by modified 2-VO method. Huatan Quyu Decoction low-, medium- and high-dosage groups were administrated with Huatan Quyu Decoction 6.1, 12.1 and 24.2 g/kg, respectively; the Western medicine group was administrated with Donepezil hydrochloride 0.5 mg/kg; the blank group and the model group were administrated with the same amount of normal saline for 28 consecutive days. On the 1st, 7th, 14th and 28th day after administration, the learning and memory ability of rats was evaluated by Morris water maze test, the levels of ACA and Aβ in serum were measured by enzyme linked immunosorbent assay (ELISA), and the expressions of β-catenin and GSK-3β proteins related to Wnt/β-catenin signal pathway in hippocampus were measured by Western blot.Results:Compared with model group, the escape latency was shortened in the Huatan Quyu Decoction high-dosage group and Donepezil group on 7 and 14 days of administration ( P<0.05), and the times of crossing the platform increased in Huatan Quyu Decoction high-dosage group on 1 and 28 days of administration ( P<0.05). Compared with model group, the serum ACA level in Donepezil group, Huatan Quyu Decoction medium- and high-dosage groups decreased at day 1, 7, 14 and 28 after administration ( P<0.05).
