Objective To analyze the diagnostic values of plasma albumin and total bilirubin, serum uric acid and inflammatory cytokines levels in patients with bipolar disorder.Methods A total of 48 cases of bipolar disorder patients were selected as research subjects ( study group) , and 45 cases of healthy people in the same period were chosen as control group.The plasma albumin, total bilirubin and serum IL-1β, IL-4, uric acid levels were compared and analyzed between two groups.Results The serum albumin, total bilirubin levels in study group were significantly lower than those in healthy control group, with significant difference (P<0.05).The serum IL-1β, IL-4 levels in study group were significantly higher than those in healthy control group, with a statistically significant difference (P<0.05).The serum uric acid levels in study group was significantly higher than that in healthy control group, with significant difference (P<0.05).Conclusion The serum albumin, total bilirubin and serum IL-1β, IL-4, uric acid levels can be used as a diagnostic reference index for bipolar disorder.

A quail-origin subtype of the influenza virus was isolated from a human-infecting H7N9 subtype of the avian influenza virus found in a live poultry market and was given the name A/Quail/Hangzhou/1/ 2013 (H9N2). We analyzed the whole genome of this virus and its biologic characteristics. Sequence analyses suggested that the: HA and NS genes belonged to a CK/BJ/1/94-like lineage; NA, NP, PA and PB1 genes belonged to a SH/F/98-like lineage; M and PB2 genes belonged to a G1-like lineage. Analyses of key amino acids showed that the cleavage site in HA protein was PSRSSR ↓ GL, and that the HA protein had a human receptor-binding site with Leu226. Deletion of amino acids 69 - 73 was detected in the stalk of NA protein, the M2 protein had an Asn31 mutation, and the NS1 protein had two mutations at Ser42, Ala149. The intravenous pathogenicity of this virus was 0.36. A study in chickens suggested that all inoculated birds shed the virus from the trachea and cloaca on the third day post-infection (p. i. ) until 11 days. All chickens that had direct contact shed the virus on the second day p. i. until 8 days. Results of virus reisolation suggested that lung and tracheal tissues could shed the virus in 5 days, whereas the other organs could shed the virus in 3 days. These results suggest that this virus strain is H9N2 subtype LPAIV, whose lineage is prevalent in mainland China. This research provides evidence on how to monitor and prevent the H9N2 subtype of the avian influenza virus.

Objective To explore the clinical significance of the coagulation and fibrolysis parameters changes for the knowledge of complicated thrombosis after chemotherapy in malignant lymphomas. Methods Morning fasting anti-coagulation blood samples were taken to detect plasma prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB) and thrombin time (TT) with automatic coagulation analyzer in 71 hospitalized malignant lymphomas and 20 normal controls. The plasma D-dimer levels of the two groups were detected with immunoturbidimetry. Results The levels of plasma APTT, Fib and D-dimer in 71 malignant lynphomas were (30.44±1.43) s, (3.28±0.20) g/L, (297.05±56.59) μg/L respectively, which were significantly higher than those in normal controls at the levels of (23.72±0.76) s, (2.57±0.22) g/L, (94.50±26.07) μg/L respectively (P ＜0.05). The coagulation and fibrolysis parameters were of no statistic differences between the normal controls and lymphomas of stage Ⅰ and Ⅱ (P ＞0.05). The APTT and Fib levels in lymphomas of stage Ⅲ and Ⅳ were higher than those in normal controls and lymphomas of stage Ⅰ and Ⅱ (P ＜0.05). There are 7 malignant lymphomas complicated venous thrombosis . Of the 7 cases, the FIB and D-dimer levels were higher than those of stage Ⅰ and Ⅱ, furthermore the D-dimer levels were higher than those of stage Ⅲ and Ⅳ. Conclusion The abnormalities of coagulation and fibrolysis parameters occurred in malignant lymphomas with requirement of periodic monitoring. After chemotherapy, the lymphoma patients had a high incidence of venous thrombosis, which need early prevention for prolongation of the survival.

AIM: To investigate the effect of antisense oligonucleotides on expression of macrophage migration inhibitory factor (MIF) in macrophages. METHODS: MIF phosphorothioate oligonucleotides was designed and synthesized. The phosphorothioate antisense, sense and missense oligonucleotides of mouse MIF was transfected into macrophages, separately. After that, macrophages were incubated with LPS. Cell culture medium was collected for MIF protein detection by EIA. Cellular RNA was extracted and the expression of MIF mRNA was examined by RT-PCR analysis. RESULTS: LPS stimulation resulted in a specific time-dependent expression of MIF derived from macrophages. MIF mRNA and MIF protein level increased at 6 h and reached a plateau at 9-12 h after LPS stimulation. The macrophages treated with antisense oligonucleotides showed a significant decrease in MIF mRNA and MIF protein after LPS stimulation than those with LPS stimulation only and LPS plus sense or missense oligonucleotides (P

Objective To investigate the prevalence and influencing factors of dysmenorrhea among female college students in Changchun city, so as to provide scientific basis for health promotion and effective preventive measurement. Methods Non-randomized convenience sampling and face to face interview were used to collect information from female college students aged between 17 and 25 years in 14 universities in Changchun. Chi-square test and logistic regression model were used to analyze influencing factors of dysmenorrhea. Results The average age of 1 071 subjects was 21.21 ± 1.83 years. The prevalence of dysmenorrhea was 86.55%. The proportion of mild dysmenorrhea among the subjects was 62.56%, followed by 33.01% with moderate dysmenorrhea and 4.43% with severe dysmenorrhea; 80.76% of subjects paid attention to keep warm in the daily life. Normal BMI, sleeping before 23 o'clock or between 23 to 24 o'clock, taking exercise frequently or everyday might be the protective factors of dysmenorrhea, and the OR values (95% CI) were respectively as 0.60 (0.37-0.97), 0.56 (0.37-0.84), 0.42 (0.22-0.78) and 0.63(0.42-0.97). Tension and the family history of dysmenorrhea might be the risk factors, and the OR values (95%CI) were respectively 1.63 (1.10-2.41), 4.84 (2.80-8.35). Conclusion The prevalence of dysmenorrhea is high among female college students. Lacking exercise, BMI less than 18.5 kg/m2, staying up late, tension and the family history of dysmenorrhea may be the influencing factors of dysmenorrhea among female college students.

Objective To assess the safety and feasibility of CT-guided percutaneous argon-helium cryoablation in the treatment of adrenal tumors.Methods 1 7 patients with adrenal tumors were treated with CT-guided percutaneous argon-helium cryoablation. Three of these patients were retreated second cryoablation three months later due to the lager tumor diameters.Percutaneous tran-scatheter arterial embolization was performed in four patients because of rich blood supply before cryoablation.Continuous arterial blood pressure monitoring was performed in eight pheochromocytoma patients.Results Technical success was achieved in all pa-tients.There were no serious complications.Eight pheochromocytoma patients experienced a significant increase in systolic blood pressure and diastolic pressure when compared with the basic values (P <0.05).There were no enhancement on enhanced CT and/or up-take on FDG PET-CT in the ablated zones during the follow-up period (3-24months).Conclusion It is safety and efficacy of CT-guided percutaneous argon-helium cryoablation for adrenal tumor.It might be initial treatment of choice for the patients who were not suitable for resection.

Objective To explore the prognostic value of modified Glasgow prognostic score (mGPS) and risk factors in predicting overall survival (OS) in the castrate-resistant prostate cancer (CRPC) treated with docetaxel-based chemotherapy.Methods We retrospectively analyzed the data of 48 consecutive Chinese patients with CRPC received docetaxel-based chemotherapy in our institution from January 2008 to January 2012.Patients were divided into three groups according to the mGPS:0,1 and 2 score groups,and compare the OS among the three groups.Variables that were influenced the efficacy of chemotherapy were included in the univariate analysis and multivariate model.Survival analysis was performed using Kaplan-Meier curves,and the differences in overall survival rates were assessed using the Logrank test.Results The follow-up was performed until April 2014.There were 48 CRPC patients including mGPS 0 score group 30 cases,mGPS 1 score group 11 cases and mGPS 2 score 7 cases.The median OS was 22,11,9 months,respectively,P＜0.01.Univariate analysis showed that:prechemotherapy baseline total prostate-specific antigen (tPSA),Eastern Cooperative Oncology Group (ECOG) score,the number of chemotherapy cycle,visceral metastasis and PSA response were associated with poor prognosis (P＜0.05).Multivariate analysis showed that:prechemotherapy mGPS 1-2 score,baseline tPSA＞60 μg/L,the number of cycles of chemotherapy≤5,with visceral metastasis and PSA response in patients with CRPC were independent risk factors for prognosis in the CRPC treated with docetaxel-based chemotherapy.Conclusion mGPS is an independent risk factor for prognosis in the CRPC patients treated with docetaxel-based chemotherapy.
