Objective:To investigate the sleep quality of the people aged over 18-years-old in Hebei province and the impact of relative factors on it.Methods:Sum total of 20 716 random samples at ages over 18 were selected among the general population.The tools were Pittsburgh Sleep Quality Index(PSQI),Simplified Coping style Questionnaire(SCSQ).Results:The total prevalence of low sleep quality was 11.6 %(2411/20716).Female had higher standardized prevalence rate than male(6.8% vs.4.8%).Logistic analysis showed that risk factors to low sleep quality were ages over 70-years-old,remarriage,divorce,bereft,negative coping style(OR=1.776,1.515,2.046,1.254,1.097).On the other hand,factors to good sleep were the Han nationality,male,farmer,the family average annual income ranged 5001-10000 RMB,10001-20000 RMB,20001-40000 RMB,positive coping style(OR=0.839,0.703,0.732,0.750,0.660,0.573,0.936).Conclusion:Low sleep quality had high prevalence in Hebei.It should be recognized by medical workers.

Objective To study the significance of detection the short term fluctuation ( SF) of macular light threshold detected by Octopus 123 automatic perimeter in suspected early age related macular dege neration (AMD). Methods SF of macular light sensitivity, Amsler chart and central visual acuity were examined in 51 patients(66 eyes) with suspected early AMD group and in 32 patients (40 eyes) in the control group. Results SF were significantly different in suspected early AMD group and control group. SF was more sensitive than the examination of central visual acuity and Amsler chart. SF was related to the quantity, location and quality of drusen. Conclusion Visual function of some suspected early AMD patients with drusen may be damaged, though the central visual acuity appears normal.

Objective To explore the features of the parental rearing behavior in schizophrenics with a brilliant school records.Methods 51 schizophrenics in remission with brilliant records were tested by EMBU.36 healthy volunteers were randomized into the controls group.Result Subjects with schizophrenia had abnormal parental rearing behavior,such as overprotection, predilection over intervention and over punishment of parents.Most of them come from peasant family.Conclusion The factors such as abnormal parental rearing behavior probably influence the development of schizophrenics.

OBJECTIVE:To provide reference for rational use of antipsychotic drugs in schizophrenia patients. METHODS:The general information and antipsychotic treatment information,which were extracted from the database of prior drug investigation in Mental Health Center of Hebei Province in 2002,2006 and investigation data in 2012 of 5014 schizophrenia patients,were ana-lyzed. RESULTS:Over time,the frequency of the first generation antipsychotic drugs decreased(P<0.05),while that of the sec-ond generation antipsychotic drugs increased (P<0.01). The frequency of long-acting antipsychotic drugs were generally low among outpatients and inpatients in 2002,2006,2012,with statistical significance(P<0.01). There were no significant difference in the proportion of outpatients receiving antipsychotic drugs combination treatment and monotherapy (P>0.05). Over time,the proportion of inpatients receiving monotherapy decreased,while that of inpatients receiving combination treatment increased (χ2=18.682,P<0.01). CONCLUSIONS:The second generation antipsychotic drugs have gradually replaced the first generation antipsy-chotic drugs,and have became the leading drugs in the treatment of schizophrenia in Hebei province. The proportion of inpatients receiving combination treatment has increased,which is different from the domestic and foreign prevention and treatment guide-lines.

Objective: This work aimed to investigate the relationships of the serum levels of IL-17 and TGF-β with the carcinogenesis and progression of colorectal cancer (CRC), as well as the clinical significance of these serum levels. Methods: Data of 30 healthy subjects, 59 patients with simple CRC and 44 CRC patients with postoperative (post-op) metastasis were recruited in this study. The patients were respectively divided into group A (30 healthy subjects as the control group), group B (59 CRC patients without distant metastasis after surgery), and group C (44 CRC patients with post-op metastasis). The patients in each group had a mean age of 53.8 ± 20.8, 62.0 ± 11.8, and 64.0 ± 15.7 years, respectively. All patients were confirmed by pathological diagnosis. The serum levels of IL-17 and TGF-β were measured by enzyme-linked immunosorbent assay. All quantitative data were analyzed using SPSS 13.0. Results: The IL-17 serum level was significantly higher in groups B and C than in group A. The preoperative (pre-op) serum level of IL-17 was significantly higher than the post-op serum level in group B (P<0.05). No significant difference was observed in the TGF-β serum levels between groups A and B, as well as between the pre-op and post-op serum levels in group B (P>0.05). However, the TGF-β serum level in group C was significantly higher than that in groups A and B (P<0.05). No significant correlation was observed in the serum level IL-17 or TGF-β between colon and rectum cancers in groups B and C. Conclusion: The serum level of IL-17 is significantly correlated with that of CRC. The serum level IL-17 increases with the aggravation of CRC and increased tumor burden. A strong correlation exists between the serum level of TGF-β and metastasis of CRC. Cytokine IL-17 and TGF-β may play an important role in the progression and metastasis of CRC.

Objective:To test the validity and reliability of the Chinese version of the Br?set Violence Check-list (BVC-C).Methods:With the authorizing permission by the author,the BVC was translated into Chinese and a-dapted,and five psychiatry experts who had worked more than 20 years were invited (3 clinical doctors and 2 nur-ses)to evaluate the content validity of the scale as the content validity index.Totally 556 inpatients who met the di-agnosis criteria for mental disorders according to the International Statistical Classification of Diseases and Related Health Problems,Tenth Revision (ICD-10)were totally selected to proceed the formal testing.The BVC scale was used to evaluate inpatients every 8 hours,the Modified Overt Aggression Scale (MOAS)was used to test concurrent validity;the results of the real attacking incidents were used to test the criterion validity;the internal consistency re-liability of the scale was tested by Cronbach αcoefficient.Results:The content validity index of the scale was0.93.In addition to the own attack subscale,the MOAS total scores and the other 3 subscales scores were positively correlated with the BVC total scores and each item score (r =0.11 -0.69,P <0.01).The best criterion validity was 8 hours through analyzed,the AUC was 0.98.When the cut-off was 2,the sensitivity and specificity were 78.9% and 95.1% respectively.The Cronbach αcoefficient was 0.76 and the item total correlations were 0.47 -0.80 (P <0.01).Conclusion:It suggests that the BVC-C has good validity and reliability,which could be used as an effective prediction tool for psychiatric violence risk assessment.

Abstract: The aim of this study was to prepare a high drug-carrying capacity micellar drug delivery system (CTD@Sol) of the polymer zebra tetracycline and to preliminarily investigate the feasibility of this drug delivery system for the treatment of breast cancer. Firstly, CTD@Sol was prepared using sol as the carrier material and CTD as the model drug, and its pharmacological properties such as appearance and morphology, particle size, potential and in vitro release were evaluated. The growth inhibitory and apoptotic effects of CTD@Sol on breast cancer (4T1) cells were investigated by MTT assay and Annexin V-FITC/PI double staining assay; the uptake efficiency of 4T1 to this delivery system was investigated by flow cytometry; and the in vivo tissue distribution of the delivery system and the targeting of tumour tissues were investigated by small animal in vivo imaging technique. The results showed that CTD@Sol appeared as a light pale blue creamy white colour, with an average particle size of (159.73 ± 1.96) nm, a PDI of 0.198 ± 0.006, Zeta potential of –(47.60 ± 1.77) mV, an encapsulation rate of (90.29 ± 1.69)% and a drug loading capacity of (45.00 ± 0. 84)%; the in vitro release and haemolysis experiments showed that the drug release rate of CTD@Sol in acidic environment (pH 5.5) was significantly faster than that in neutral environment (pH 7.4), suggesting that the system is acid-sensitive and has good biosafety under endocytosed pH conditions. Cellular uptake, cytotoxicity and apoptosis experiments showed that CTD@Sol was more lethal to 4T1 cells, and the sol-gel polymer micelles as a drug delivery vehicle could significantly improve the cellular uptake efficiency of the drug; in vivo experiments showed that the delivery system had a significant targeting effect on tumour tissues.In conclusion, this study has successfully produced a CTD@Sol drug delivery system with high drug loading capacity (>45%), good pharmacological performance, strong targeting and biosafety, which has the potential to be used in the treatment of breast cancer.

Nasopharyngeal carcinoma (NPC) is a common malignant tumor in China. Radiotherapy is the first-line treatment. After appropriate radiotherapy, about 5%-15% patients experience recurrence. In view of the poor efficacy and high incidence of severe late toxicities associated with re-irradiation, salvage surgery by the transnasal endoscopic approach is recommended for recurrent NPC (rNPC). Compared with re-irradiation, endoscopic surgery can better prolong survival, improve the quality of life, and reduce complications and medical expenses of patients with rNPC. However, the complexity of the nasopharyngeal skull base enhances the difficulty and risk of surgery. Expanding the boundary of surgical resection remains a clinical challenge for otolaryngologists. In this regard, to help more advanced patients with rNPC, the surgical innovative system of NPC needs to be established by multi-disciplinary cooperation, involving skull base anatomy-based investigation, appropriate administration of the internal carotid artery (ICA), repair of skull base defect, and establishment of various types of endoscopic endonasal nasopharyngectomy.

Primary age-related tauopathy (PART) is characterized by tau neurofibrillary tangles (NFTs) in the absence of amyloid plaque pathology. In the present study, we analyzed the distribution patterns of phosphorylated 43-kDa TAR DNA-binding protein (pTDP-43) in the brains of patients with PART. Immunohistochemistry and immunofluorescence double-labeling in multiple brain regions was performed on brain tissues from PART, Alzheimer's disease (AD), and aging control cases. We examined the regional distribution patterns of pTDP-43 intraneuronal inclusions in PART with Braak NFT stages > 0 and ≤ IV, and a Thal phase of 0 (no beta-amyloid present). We found four stages which indicated potentially sequential dissemination of pTDP-43 in PART. Stage I was characterized by the presence of pTDP-43 lesions in the amygdala, stage II by such lesions in the hippocampus, stage III by spread of pTDP-43 to the neocortex, and stage IV by pTDP-43 lesions in the putamen, pallidum, and insular cortex. In general, the distribution pattern of pTDP-43 pathology in PART cases was similar to the early TDP-43 stages reported in AD, but tended to be more restricted to the limbic system. However, there were some differences in the distribution patterns of pTDP-43 between PART and AD, especially in the dentate gyrus of the hippocampus. Positive correlations were found in PART between the Braak NFT stage and the pTDP-43 stage and density.
