Objective To investigate the prevalence and severity degree of post traumatic stress disorder(PTSD), anxiety and depression, and to explore the different mental profile in different groups involved with an earthquake. Methods 26 days after 8.0 grade earthquake in Wenchuan, psychological rescue team of State Administration of Traditional Chinese Medicine went to some communities in Deyang and Mianzhu area of Sichuan province. In this period, a total of 119 survivors, including students(42), teacher(40) and masses(37), were investigated through impact of event scale (IES), self-rating anxiety scale (SAS) and self-rating depression scale(SDS). Results①The detection rate of score over 19 in IES in 3 groups (students, teacher and masses) were 69％, 80％ and 91.9％, respectively. There was significant difference among these 3 groups (F=5.611, P=0.005<0.01) in respect of severity degree of PTSD. ②The values of severity degree of anxiety in 3 groups were significant higher than normal value (P<0.001, all). There was also significant difference among these 3 groups (F=3.376, P=0.038<0.05) in respect of severity degree of anxiety, with the masses group being significant higher than student and teacher group (P=0.029, P=0.022, respectively). ③The values of severity degree of depression in these 3 groups were significant higher than normal value (P<0.05, all). But there was no significant difference (F= 0.670, P=0.514) among these 3 groups. ConclusionThe results suggested the importance to assess PTSD, anxiety and depression in post-disaster area, especially PTSD and anxiety evaluations in the masses group.

Objective: To investigate the epidemic status and influencing factors of colorectal polyps among urban residents in Lanxi. Methods: A representative urban community was selected from Lanxi. A total of 935 local residents aged 18-80 years received questionnaire survey,physical examination,laboratory tests and colonoscopy. Multivariate Logistic regression analysis was applied to exam the potential influencing factors for colorectal polyps. Results : Eventually 880 residents were involved into the statistical analysis. Colorectal polyps were detected in 167 participants with a crude prevalence of 18.98% and adjusted prevalence for age and gender of 13.28%. The prevalence of colorectal polyps in men（28.70%）was significantly higher than that in women（12.92%,P<0.05）. The results of logistic regression analysis showed that age（OR=1.038,95%CI：1.018-1.057）,males（OR=1.919,95%CI：1.303-2.826）,the middle school level of education（OR=2.443,95%CI：1.507-3.961）and constitution of Yin-Asthenia（OR=0.203,95%CI：0.057-0.720）were influencing factors for colorectal polyps;among male participants,hypertension（OR=1.721,95%CI：1.018-2.908）was a risk factor for colorectal polyps;among female participants,age（OR=1.076,95%CI：1.042-1.111）,BMI（OR=1.099,95%CI：1.001-1.207）,the middle school level of education（OR= 3.507,95%CI：1.794-6.856）and constitution of Yin-Asthenia（OR=0.160,95%CI：0.033-0.770）were influencing factors for colorectal polyps. Conclusion Age,sex,education level and constitution of Yin-Asthenia were associated with the risk of colorectal polyps among residents in Lanxi;hypertension was associated with the risk of colorectal polyps in males,while age,BMI,education level and constitution of Yin-Asthenia were associated with the risk of colorectal polyps in females.

Combined central and peripheral demyelination (CCPD) is a rare autoimmune disease and its action mechanism remains unknown. This article described a case of CCPD with anti-neurofascin 155 IgG4 antibodies after varicella-zoster virus (VZV) infection who was recovered after steroids and intravenous immunoglobulin treatments. The clinical characteristics of this patient were summarized and the possible pathogenesis was discussed, so as to provide information of CCPD after VZV infection for clinicians.

Objective To analyze the clinical features and prognosis of anti-leucine rich glioma inactivated protein 1 (LGI1) encephalitis.Methods Twelve encephalitis patients with anti-LGI1 antibodies were collected from the First Affiliated Hospital of Zhengzhou University from June 2015 to December 2016.The clinical manifestations,electroencephalogram,laboratory examination and imaging findings were summarized and the prognosis was observed.The modified Rankin Scale (mRS) was used for evaluation before and after treatment.Results The major clinical features included memory deficit (10/12),spatial disorientation (7/12),epilepsy with generalized tonic-clonic seizures (9/12),faciobrachial dystonic seizures (7/12),hyponatremia (5/12),mental and behavioral abnormalites (1/12),light sleep (1/12),increased sleep (3/12),aphasis (4/12),dysphagia,choking (2/12),headache (1/12),dizziness (2/12),fatigue (2/12),ataxia (2/12),bradycardia (3/12),urinary disorders (2/12),intestinal obstruction (1/12),diarrhea (1/12).Admission mRS score was found to be three in eight cases,four in four cases.The abnormal electroencephalogram was found in six cases,mainly manifested as focal or diffuse slow wave,some accompanied by epileptic wave.MRI scan of brain showed abnormal signals in four cases,mainly involved medial temporal lobe,hippocampus,basal ganglia,while one patient avoided MRI scan due to implantation of pacemaker.Two patients presented with pulmonary nodules,one case with positive thyroid antibody and increased rheumatoid factor.The follow-up after treatment showed no one died;mRS score was two in two cases,one in nine cases and zero in one case;the sequelae were memory deficit,increased sleep,faciobrachial dystonic seizures.Conclusions Anti-LGI1 encephalitis is a treatable disease,cardinal clinical features of which are seizures,cognitive disorders,hyponatremia.Immunotherapy can improve the symptoms of the disease significantly,and the prognosis is better comparatively.

Objective:To construct a recombinant bioluminescent bacteriophage (HT7) targeting Escherichia coli, and evaluate its ability to identify Escherichia coli. Methods:Initially, pCRISPR-sg (1-10) and PFN-1000 plasmid strains were constructed by genetic engineering, and the most efficient small guild RNA (sgRNA) were screened by bilayer plate. By the gene editing technique, which comprised homologous recombination and clustered regularly interspaced short palin dromic repeats (CRISPR)-Cas system, the Nanoluc luciferase gene was integrated into the downstream non-coding region of 10A gene of T7 phage, to constructe the bioluminescent phage HT7 successfully. The difference of biological characteristics between HT7 phage and T7 phage was evaluated by plaque assay and liquid amplification assay. In addition, 51 strains of Escherichia coli, 20 strains of Klebsiella pneumoniae, 14 strains of Staphylococcus aureus, 6 strains of Enterococcus faecium, 5 strains of Enterococcus faecalis, 3 strains of Acinetobacter baumannii and 1 strain of Pseudomonas aeruginosa were collected and isolated to evaluate the limit of detection and specificity of HT7 phage. Results:Among the 10 CRISPR-targeted cleavage systems constructed, sgRNA8 exhibited the highest cleavage efficiency, with a cleavage rate of 0.18. After three rounds of recombination screening using the pCas9/pCRISPR/PFN-1000 triple-plasmid system, PCR validation yielded recombinant phage bands at 2 798 bp, indicating the successful construction of the HT7 phage. The recombinant phage showed significant differences in biological characteristics in terms of lysis efficiency ( P<0.001), one-step growth curve ( P=0.001), and infection multiplicity ( P=0.031). Both lysis burst time and log growth node were extended by 10 min, with the optimal infection multiplicity being 0.1. Clinical sample testing identified lysis of 6 strains of Escherichia coli within 4.5 h, while other strains remained unaffected, with detection of pathogenic bacteria below 10 CFU/ml. Conclusions:The developed pCas9/pCRISPR/PFN-1000 triple-plasmid editing system efficiently edits the bacteriophage genome. The constructed HT7 fluorescent bacteriophage enables the detection of Escherichia coli below 10 CFU/ml within 4.5 hours, demonstrating low detection limits and high detection specificity.
