Objective To develop a method for determination of 18 organophosphorous and carbamate pesticides in human plasma by UPLC-MS/MS. Methods Following deproteinization by acetonitrile, an aliquot of the biological sample was injected into a C18 column(1.7μm 2.1×50mm) using 5mmol/L Ammonium acetate-methanol as the mobile phase with the flow rate of 0.3mL/min, the injection volume was 10μL. Electro spray ionization(ESI) Indicators source was applied and operated in positive ion mode, and multiple reaction monitoring(MRM) mode was used to quantify. Results The limits of detection(LODs) in human plasma ranged from 0.1 to 40ng/mL, and the limits of quantitation(LOQs) ranged from 0.5 to 50ng/mL. An excellent linearity was observed for these LOQs up to 50ng/mL. The average extraction recoveries were with in 64.3%~111.9%, relative standard deviation(RSD) is 3.9%~10.3%. Conclusion This method is specific, sensitive and accurate, and can be used to detect pesticides in forensic.

Objective:To investigate the post-traumatic stress response in women with unintended pregnancy termination and analyze its related factors.Methods:Totally 388 women with unintended pregnancy termination from two public hospitals in Fujian were selected as the research subjects.They were assessed with the Impact of E-vent Scale-Revised(IES-R),Hospital Anxiety and Depression Scale(HADS),Connor-Davidson Resilience Scale(CD-RISC)and Perinatal Grief Scale(PGS).The total score of IES-R ≥35 was positive for post-traumatic stress disorder screening.Results:The total score of IES-R was(20.6±12.4),and the positive rate of post-traumatic stress disorder screening was 16.5%.Multiple linear regression analysis showed that the IES-R total scores were higher in those who thought pregnancy timing was appropriate than those who thought pregnancy timing was wrong(β=0.13),and lower in women with moderate pain during termination than in those with severe pain(β=-0.09).The IES-R total scores were positively correlated with gestational weeks,depression scores of the HADS and grief scores of the PGS(β=0.18,0.27,0.16),and negatively correlated with optimism scores of the CD-RISC(β=-0.12).Conclusion:The post-traumatic stress response of unintended termination of pregnancy is at a moder-ate level.Post-traumatic stress symptoms are more likely to occur in women who thought pregnancy timing is ap-propriate,and those with severe pain during pregnancy termination,large gestational weeks,high level of depression during pregnancy,and high level of grief after pregnancy termination.

Objective To investigate the clinical features of Parkinson disease (PD)with constipation.Methods From October 2013 to August 2015,a total of 204 PD patients were consecutively recruited from the Departments of Geriatrics and Neurology,Beijing Tiantan Hospital,Capital Medical University,and were evaluated by Rome Ⅲ diagnostic criteria for functional constipation and other related scales of motor symptoms(MS)and non-motor symptoms(NMS),the activity of daily living(ADL)and quality of life.Results Overall,131 of 204(64.2%)PD patients with constipation were assigned to the PD-C group and 73 of 204 (35.8%)PD patients without constipation were assigned to the PD-NC group.In the PD-C group,38 of 131(29%)PD patients had constipation before motor symptoms occurred.The mean age and age of onset in the PD-C group were significantly older than those in the PD-NC group (64.13 ± 9.67 vs.58.35 ± 11.37;60.07 ± 10.46 vs.55.10±12.97;F=2.287,4.948;t=3.827,-2.788;P<0.01 for both).Meanwhile,compared with the PD-NC group,the PD-C group was associated with dramatically longer disease duration (2.25,range:1.00-5.00 vs.2.00,range:1.00-3.13;Z =-2.254;P < 0.05),increased scores of the Unified Parkinson Disease Rating Scale (UPDRS) Ⅲ (26.00 scores,range:18.00 37.50 vs.19.00,range:12.50-31.00;Z =-2.349,P < 0.05),more advanced stages on the Hoehn-Yahr (H-Y) scale (2.00 stage,range:1.50-2.50 vs.1.50,range:1.00-2.50;Z=-2.334,P<0.05),higher total numbers of NMS(11.00,range:6.00-15.00 vs.6.00,range:3.00-11.00;Z=-3.715,P<0.05),and higher numbers of NMS occurring before and after MS(before,2.00,range:0.00-4.00 vs.1.00,range:0.00-2.00;after,8.00,range:3.00-14.00 vs.5.00,range:2.00-9.50;Z =-2.612,-2.630,respectively;P<0.05 for both).Additionally,there were significant differences between the groups in the scores of the Hamilton depression scale (HAMD),the Hamilton anxiety scale (HAMA),the Pittsburgh sleep quality index (PSQI),the scales for outcomes in Parkinson disease-autonomic (SCOPA-AUT),the Fatigue severity scale (FSS),the Apathy scale,the Montreal Cognitive Assessment(MoCA)scale,the UPDRS Ⅱ and ADL Scale,and the PDQL-39 (all P<0.05).Binary Logistic regression analysis showed that age,SCOPA-AUT,HAMA and HAMD were risk factors for PD-C(OR=1.091,1.107,1.10 and 1.080;P<0.05 for all).Conclusions PD patients have a high incidence of constipation,and more than a quarter of patients have constipation before MS occurs.Meanwhile,PD patients with constipation are usually associated with old age and late age of onset,long disease duration,severe MS,frequent and severe NMS,bad cognition,emotional state and sleep,severe fatigue,and apathy.Moreover,advanced age,autonomic dysfunction,anxiety and depression increase the risk of PD with constipation.Constipation has a serious negative impact on the activity of daily living and quality of life in PD patients.

Tinosporae Radix, as a traditional Chinese medicinal herb, is the dried root tuber of Tinospora sagittata or T. capillipes. It was first recorded in the Compendium of Materia Medica Supplement in the Qing Dynasty and included in the previous edition of the Chinese Pharmacopoeia. Tinosporae Radix is excavated in autumn and winter and used after removing fibrous roots, washing, and drying. It is indicated for sore throat, carbuncle boils poison, waist and abdominal pain, and various heat syndromes and is commonly used to treat chronic inflammation. Its efficacy is significantly known as “broad-spectrum antibiotics in Zhuang medicine”. Tinosporae Radix is a traditional Chinese medicinal herb often taken by Zhuang and Yao nationalities in Guangxi province and has a wide range of application and development values and research significance. Modern studies have shown that Tinosporae Radix contains diterpenoids, alkaloids, sterols, anthraquinones, glycosides, fatty acids, volatile oils, and other compounds, which have many pharmacological activities such as anti-inflammatory and analgesic, antibacterial and antibacterial, antioxidant, anti-diabetic, and anti-tumor and anti-cancer effects, and it has achieved good efficacy in inhibiting inflammation and treating sore throat and other diseases. In recent years, there have been many research reports on the status, chemical constituents, pharmacological action, clinical application, and quality evaluation of Tinosporae Radix resources, but there is no systematic review and introduction at present. By consulting the literature and combining it with modern research, this paper systematically summarizes and collates Tinosporae Radix resources to provide guidance for the comprehensive development and utilization of Tinosporae Radix resources and subsequent in-depth study.

Objective:
To investigate the clinical characteristics of sleep disorders(SD)in patients with Alzheimer's disease(AD), and the relationship between SD and cognitive impairment.
Methods:
According to the inclusion and exclusion criteria of AD, 89 consecutive AD patients admitted to Beijing Tiantan Hospital from January 2016 to January 2017 were included.The Pittsburgh sleep quality index(PSQI)scale was used to evaluate the overall sleep status.The patients were randomized into the AD with SD(AD-SD)group(PSQI>7)and the AD without SD(AD-NSD)group(PSQI<7). The cognitive function of AD patients was evaluated by the Montreal cognitive assessment(MoCA)scale, and the overall cognitive function and cognitive domains were compared between the AD-SD and AD-NSD groups.
Results:
Of the 89 AD patients, 71 cases(79.78%)had SD.There was no significant difference in gender, age, age of onset, education level and disease duration between the AD-SD and AD-NSD groups(
