Effects of Pearl Yangxin Anshen Decoction on HAMD and PTSD-SS Scores, Cytokines and Related Metabolites in Patients with Post-Traumatic Stress Disorder

Objective: This paper aims to observe the Pearl Yangxin Anshen Decoction to influence the score of HAMD and PTSD-SS, the changes of the cytokines and the related metabolic product in patients with PTSD. Methods: From June 2015 to May 2016, in the traditional Chinese medicine clinics of Hainan Province People’s Hospital, there were 50 patients with PTSD, the age were from 30 to 60, they were randomly divided into treatment group (25 cases) and control group (25 cases), then compared the scores of HAMD and PTSD-SS between the two groups, searched the changes of cytokines and the related metabolic product. Results: In the treatment group: before and after treatment the scores of PTSD-SS were 65.64 ± 7.02, 28.32 ± 4.18, and the scores of HAMD were 29.28 ± 1.97, 11.72 ± 2.13;In the control group: before and after treatment the scores of PTSD-SS were 63.24 ± 6.16, 31.40 ± 4.29, the scores of HAMD were 30.24 ± 2.05, 13.08 ± 2.30. After 3 months patients in treatment group the scores of PTSD-SS and HAMD were lower than the control group (t = 2.570, P = 0.013, t = -2.1640, P = 0.035). In the control group: before and after 3 months treatment the IL-2 levels respectively were 79.84 ± 26.46 pg/ml, 56.18 ± 22.67 pg/ml, the IL-6 levels respectively were 110.83 ± 47.65 pg/ml, 59.67 ± 44.68 pg/ml, the IL-8 levels respectively were 73.11 ± 78.51 pg/ml, 55.83 ± 81.94 pg/ml, the NE levels respectively were 420.04 ± 674.75 pg/ml, 185.31 ± 417.91 pg/ml, the MDA levels respectively were 112.35 ± 62.87 ng/ml, 60.42.33 ± 53.64 ng/ml, the NO levels were 126.6 ± 47.4 μmol/L, 78.6 ± 45.7 μmol/L, the VIP levels were 396.6 ± 144.4 pg/ml, 122.4 ± 111.5 pg/ml. In the treatment group: before and after 3 months treatment the IL-2 levels respectively were 86.00 ± 32.29 pg/ml, 53.84 ± 27.01 pg/ml, the IL-6 levels respectively were 108.21 ± 44.60 pg/ml, 42.46 ± 42.16 pg/ml, the IL-8 levels respectively were 81.48 ± 94.19 pg/ml, 54.07 ± 84.15 pg/ml, the NE levels respectively were 392.93 ± 592.84 pg/ml, 243.85 ± 588.45 pg/ml, the MDA levels respectively were 117.58 ± 63.37 ng/ml, 45.91 ± 38.94 ng/ml, the NO levels respectively were 135.9 ± 46.4 μmol/L, 72.6 ± 46.6 μmol/L, the VIP levels respectively were 414.0 ± 140.1 pg/ml, 185.8 ± 105.3 pg/ml. In the two groups as the extension of treatment time, the content of IL-2, IL-8, IL-6, NE, MDA, NO, and VIP were gradually reduced, and the level of reduction of the treatment group patients was higher than the control group, the change of ACTH and SOD levels just the opposite. Conclusion: The Pearl Yangxin Anshen Decoction could improve the symptoms of psychological anxiety, depression and other psychological problems in patients with PTSD, and influence the change of cytokines and related metabolites product.

Serological Detection,Risk Factor Analysts and Statistical Mapping of Brucellosts in Females of KP Pakistan

Among the most well-known zoonotic maladies,Brucellosis is the one having a lot of clinical presentations.Brucellosis is a disease which is caused by a type of bacteria of the genus Brucella.Brucellosis is common in people who work as shepherd,milkman,butcher,knackers and vertinary assistants.The different types of the tests are used to diagnose brucellosis such as(ELISA)Enzyme Linked Immunosorbent Assay,(RBPT)Rose Bengal Plate Test and many others.From literature it is evident that the picture of brucellosis is not clear in many countries including Pakistan.So the aim of the study is to clear the exact status of the disease in the women of agro ecological zones of KP Pakistan.A multistage sampling will be used by dividing KP in different agro ecological zones and blood will be collected from the women who are in close contact with animals.The serum will be isolated and the samples will be tested for Brucella by commercial serological kits i.e.ELISA kit in the laboratory for the comparison of the disease status in women of different agro ecological zones of KP Pakistan.

Suspected SARS-CoV-2 infection with fever and coronary heart disease:A case report

BACKGROUND The coronavirus disease 2019(COVID-19)is an emerging infectious disease caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Suspected cases accounted for a large proportion in the early stage of the COVID-19 outbreak.The deviation of the nucleic acid test by throat swab(the current gold standard of COVID-19)caused by variation in sampling techniques and reagent kits and coupled with nonspecific clinical manifestations make confirmation of the suspected cases difficult.Proper management of the suspected cases of COVID-19 is crucial for disease control.CASE SUMMARY A 65-year-old male presented with fever,lymphopenia,and chest computed tomography(CT)images similar to COVID-19 after percutaneous coronary intervention.The patient was diagnosed as having bacterial pneumonia with cardiogenic pulmonary edema instead of COVID-19.This was based on four negative results for throat swab detection of SARS-CoV-2 nucleic acid using reverse transcriptase-polymerase chain reaction assay and one negative result for serological antibody of SARS-CoV-2 with the serological assay.Additionally,the distribution of ground-glass opacities and thickened blood vessels from the CT images differed from COVID-19 features,which further supported the exclusion of COVID-19.CONCLUSION Distinguishing COVID-19 patients from those with bacterial pneumonia with cardiogenic pulmonary edema can be difficult.Therefore,it requires serious identification.

A novel luciferase immunosorbent assay performs better than a commercial enzyme-linked immunosorbent assay to detect MERS-CoV specific IgG in humans and animals

The Middle East respiratory syndrome(MERS)is a lethal zoonosis caused by MERS coronavirus(MERS-CoV)and poses a significant threat to public health worldwide.Therefore,a rapid,sensitive,and specific serologic test for detecting anti-MERS-CoV antibodies in both humans and animals is urgently needed for the successful management of this illness.Here,we evaluated various novel luciferase immunosorbent assays(LISA)based on nucleocapsid protein(NP)as well as fragments derived from spike protein(S)including subunit 1(S1),N terminal domain(NTD),receptorbinding domain(RBD)and subunit 2(S2)of S for the detection of MERS-CoV-specific IgG.Fusion proteins,including nanoluciferase(NLuc)and various fragments derived from the NP or S protein of MERS-CoV,were expressed in human embryonic kidney 293 T cells.LISAs that detected anti-MERS-CoV IgG were further developed using cell lysates expressing various fusion proteins.Panels of human or animal samples infected with MERS-CoV were used to analyze the sensitivity and specificity of various LISAs in reference to a MERS-CoV RT-PCR,commercial S1-based ELISA,and pseudovirus particle neutralization test(ppNT).Our results showed that the S1-,RBD-,and NP-LISAs were more sensitive than the NTD-and S2-LISAs for the detection of anti-MERS-CoV IgG.Furthermore,the S1-,RBD-,and NP-LISAs were more sensitive(by at least 16-fold)than the commercially available S1-ELISA.Moreover,the S1-,RBD-,and NPLISA specifically recognized anti-MERS-CoV IgG and did not cross-react with samples derived from other human CoV(OC43,229E,HKU1,NL63)-infected patients.More importantly,these LISAs proved their applicability and reliability for detecting anti-MERS-CoV IgG in samples from camels,monkeys,and mice,among which the RBD-LISA exhibited excellent performance.The results of this study suggest that the novel MERS-CoV RBD-and S1-LISAs are highly effective platforms for the rapid and sensitive detection of anti-MERS-CoV IgG in human and animal samples.These assays have the potential to be used as serologic tests for the management and control of MERS-CoV infection.
