OBJECTIVE: To explore the relevance between writing characteristic and therapeutic effect in schizophrenia and to discuss the influence of aggressive behavior on writing characteristic. METHODS: Recoding the casual and fixed writing in admission, one week, two weeks, four weeks, eight weeks after treatment and rating Positive and Negative Syndrome Scale (PANSS) and Modified Overt Aggression Scale (MOAS). Choosing two characteristics, "relationship between font and grid lines" and "having big strokes or not", and comparing before and after treatment. RESULTS: Eight weeks after treatment, the score of PANSS decreased. The condition of patients and the writing characteristic improved as well. The differences of writing characteristics were statistically significant in patients with aggressive behavior before and after treatment (P < 0.05). CONCLUSION The writing characteristic has relation with therapeutic effects and improved with therapeutic effects in aggressive patients.

Background Vascular endothelial growth factor(VEGF) has been shown to be associated with the pathogenesis of age-related macular degeneration (AMD),therefore VEGF is a target for the treatment of wet AMD.However,the mechanism of VEGF in the pathogenesis of AMD is not clearly understood.Studying the correlation between VEGF gene polymorphism and AMD is becoming a new research hotspot,but relevant studies on Han Chinese have not been performed.Objective This study was to investigate the association between the VEGF +936C/T gene polymorphism and AMD in the Chinese population.Methods A pilot prospective and nonrandomized controlled trial was designed.This protocol complied with Declaration of Helsinki and was approved by the Ethic Committee of Chinese PLA Second Artillery General Hospital.Written informed consent was obtained from each subject prior to entering the study.Two hundred AMD patients and 200 age-and gender-matched normal controls were enrolled in this study.The genomic DNA was extracted from the peripheral blood samples of the subjects,and analysis of the VEGF polymorphisms at the +936 position in the promoter and 3＇-untranslated regions was performed by the restriction fragment length polymorphism method.Frequencies of the VEGF+936C/T genotype were compared between the two groups,and the risk of the VEGF+936C/T gene polymorphism in pre-disposing AMD was evaluated.Results No significant differences were seen in the incidence rates of smoking(P ＝ 0.76),hypertension(P ＝ 0.84),hyperlipidemia (P=0.71),diabetes mellitus (P=0.86) and cardiovascular disease(P=0.89) between the AMD group and the normal control group,and BMI was matched between the two groups (P =0.18).The prevalence of the TT genotype was 9.0％ (18/200)in the AMD group,but that in the normal control was 3.5％ (7/200),showing a significant difference between the two groups (P =0.03).The odds ratio (OR) was 2.73 with a 95％ confidence interval(CI) of 1.11 to 6.68 for AMD in this genotype.The CC and CT genotypes were not significantly different between the two groups (P =0.52,P =0.57).The genotype frequency and allele frequency conformed to HardyWeinberg equilibrium law.There were no significant differences found in the CC,CT,TT genotype frequencies among the early AMD,geographic atrophy AMD and choroidal neovascular AMD (all at P＞0.05).Conclusions The VEGF+936TT genotype is associated with AMD in Han Chinese population.

Objective To investigate the change of local vaginal microenvironment in atrophic vaginitis after estrogen therapy.Methods A prospective study was conducted in 128 patients with atrophic vaginitis.The patients were treated with estriol cream by vaginal administration,and the efficacy was observed after treatment.Results The PH value was decreased and the detection rate of lactobacilli was significantly increased after estrogen therapy(P＜0.01).Average vaginal health score was also increased (P＜0.01).Interleukin-6 (IL 6) level in vaginal secretion was decreased after the treatment (P＜0.01).Interferon-γ (INF-γ) level was increased obviously after treatment,while there was no significant difference between the two groups(P＞0.05).Conclusions Estrogen can significantly improve the local vaginal microenvironment in atrophic vaginitis.Estrogen may regulate the immune function of vagina by reversing the imbalance of Th1/Th2.

Objective To investigate the effect and mechanisms of recipient-derived immature dendritic cells(imDC) transfected with IKK2dn and loaded with donor antigen on renal allografts survival in the rats.Methods DC were cultured from recipient rats'(Lewis) bone marrow,transfected with IKK2dn and loaded with donor antigen.The expression of CD86 and MHC Ⅱ was detected,and the ability of DC stimulating lymphocyte proliferation in vitro was measured.Male Brown Norwav rats and Lewis rats were used as donors and recipients respectively.Four groups were set up(DC group,empty transfection group,transfection group and control group),receiving 1×10~7 DC,Adv-0-DC,Adv-IKK2dn-DC loaded with BN antigen,and equal volume of normal saline,respectivelv 7 davs before transplantation.In the third party donor-group,Wistar rats as donors were treated the same as DC;group before transplantation.After transplantation,the T lymphocyte proliferation in reciPients was measured and the expression of serum IL-2 and IFN-γ was detected.The survival time of recipients and the acute reiection were observed.Pathological changes were examined tO identify the grade of rejection.Results DC assessment in vivo revealed that the transfected DC could still express CD86 and MHC Ⅱ in a low level as compared with those not transfected with IKK2dn. After DC were loaded with donor's antigen,the expression of CD86 and MHC Ⅱ was up-regulated.After DC were transfected with IKK2dn before loaded with donor's antigen, the expression of CD86 and MHC Ⅱ had no significant change. When DC were loaded with donor's antigen, its allostimulatory activity of T lymphocyte proliferation was enhanced (P<0. 05). When DC were transfected with IKK2dn before loaded with donor's antigen, its allostimulatory activity of T lymphocyte proliferation was not enhanced. Compared with control groups, IKK2dn-transfected DC pulsed with BN splenocyte lysate markedly prolonged the survival of renal allografts (26. 8±1.76d, P<0.01), and elicited markedly lower proliferative responses and reduced IL-2 and IFN-γ production. The pathological grade of rejection was low in the transfection group. Conclusion Recipient-derived imDC transfected with IKK2dn and loaded with donor splenocyte lysate could prolong the renal allograft survival in rats probably by down-regulating the expression of DC costimulatory molecules and inhibiting the T_H 1 cytokine production.

Objective To evaluate the response rate and survival rates of refractory or relapsed Hodgkin lymphoma (HL) and grey zone lymphoma patients treated with autologous peripheral blood stem cell transplantation (APBSCT).Methods From January 2004 to August 2012,30 HL and grey zone lymphoma patients were retrospectively analyzed.Statistical analysis was done to explore the long term outcome and prognostic factors of patients treated with APBSCT.Among all patients,the median age at transplantion was 30 (13-55) years old.Patients were major with nodular sclerosis HL and in stage Ⅲ/Ⅳ.Results Every patient had a successful collection.The median MNC cell dose infused was 6.8×108/kg [range (1.0-13.8)×108/kg] and median CD34+ cell dose infused was 6.3×106/kg [range (0.6-20.6)×106/kg].Median time to neutrophil engraftment was 9 days (range 8-12 days).28 patients were evaluable after transplantation with a median follow-up of 18.5 months (range 2.5-95.0 months).The overall response rate was 89.3 ％ [CR 64.3 ％ (18/28),PR 25.0 ％ (7/28)].The overall survival (OS) rate and progression free survival (PFS) rate at 5 year would be 78 ％ and 58 ％ for all patients.3 in 7 patients with no remission after salvage chemotherapy with rituximab plus chemotherapy before APBSCT got CR and 2 got PR.Univariate analysis showed that disease status and the number of replacement types of chemotherapy prior to transplantation affected OS,the history of radiotherapy prior to transplantation affected PFS.Conclusion APBSCT can increase CR rate,prolong survival time in patients with refractory or relapsed HL and grey zone lymphoma.Rituximab plus chemotherapy as a salvage therapy could raise CR rate before APBSCT.Chemosensitivity before transplantation affect outcome with APBSCT.Changing many types of chemotherapy is adverse for APBSCT.Salvage radiotherapy before APBSCT is not recommended.

Objective To evaluate the efficacy of anti-CD20 monoclonal antibody (Rituximab) combined with autologous hematopoietic stem cell transplant (ASCT) in treatment of the patients with B cell non-Hodgkin lymphoma (NHL). Methods Twenty-one patients with B-cell NHL(CD20 positive) received ASCT with Rituximab at the dose of 385 mg·m-2·d-1 on day 1 and day 8 of mobilization,and day -1 and day +7 of conditioning regimen. Among the 21 patients receiving chemotherapy before the transplant, five cases achieved complete response (CR), eleven cases achieved partial remission (PR), and 5 cases had the progression of disease (PD) after many cycles of chemotherapy. Results The median follow-up was 24 months (1-68 months) in the present study. No relapse occurred among the 5 patients in CR before the transplant. Only one of the 11 PR patients relapsed 6 months post-transplantation. Three of the 5 PD patients died. Four of 21 cases (19 %) were documented as recurrence and death, the other 17 cases remained alive and disease-free. Both 2-year EFS and OS of these cases were 81%. No harmful effect of Rituximab was observed on the quality and quantity of collected stem cells as well as hematopoietic recovery post SCT. Conclusion The efficacy of ASCT with Rituximab in vivo purging in the patients with B-cell NHL was determined mainly by the disease status before transplant. The approach may be used as consolidation therapy to achieve long-term survival and increase the curable rate for patients in CR before transplant, and as intensification therapy to increase the remission rate and prolong the EFS and OS of the patients in PR. Rituximab did not show any adverse effect on collection and reconstitution of hematopoietic stem cells.

Objective:To establish a method for the determination of omeprazole delayed release capsules and investigate the be-havior of reference preparations to provide experimental basis for generic drugs quality consistency evaluation. Methods:According to the first dissolution method (basket method) stated in 0. 931 of Chinese Pharmacopeia (2015 edition), the type of release media, solu-bility and stability of omeprazole in different media, effect of different treatment methods on the drug adsorption in the solution, differ-ent rotation speed and the methodology of ultraviolet spectrophotometry were investigated. Results:The rotation speed was 75 r·min-1 with the dissolution medium volume of 900 ml. The dissolution profiles of omeprazole delayed release capsules in three different media ( pH 6. 0 phosphate buffer, pH 6. 8 phosphate buffer and water containing 3% Tween-80) were determined with online filteration. The solubility of omeprazole in the different media was 0. 123, 0. 078 and 0. 275 mg·ml-1 , respectively. The results showed that ome-prazole was degraded 44%, 8% and 14% in 2 h in the above three release media, and degraded up to 43% in 6 h in water containing 3% Tween-80. The linear of omeprazole was 0. 209 4-20. 94, 0. 204 8-20. 48 and 0. 2016-20. 16 μg·ml-1 with the average recovery of 99.3% (RSD=0.7%,n=12), 99.7% (RSD=0.9%,n=12) and 99.5% (RSD=0.6%,n=12) respectively in the three media. Conclusion:The method is accurate and reliable, which can be used to study the quality consistency of omeprazole delayed re-lease capsules.

BACKGROUND:Hyperglycemia has been detected in many critically ill patients in the department of emergency medicine. But its mechanism and prognosis have not been well elucidated. In this study, we measured the serum level of glycated hemoglobin A1C (HbA1c) in critically ill patients to evaluate the effects of hyperglycemia on the prognosis of the patients.METHODS:A total of 826 critically ill patients, who had been treated at the Department of Emergency Medicine of Chaoyang Hospital during October 2006 and November 2007, were divided into a diabetes mellitus group (n=184) and a non-diabetes mellitus group (642) according to whether they had diabetes mellitus. Fasting glucose and HbA1c were measured in all patients. Those in the diabetes mellitus group were further assigned to a drug therapy subgroup and a non-drug therapy subgroup; the serum level of HbA1c and its relationship with short-term outcome were evaluated.RESULTS:Fasting glucose increased in 78.8％ of the patients (88.6％ in the diabetes mellitus group, and 75.9％ in the non-diabetes mellitus group,P<0.05), and HbA1c was elevated in 45.5％ of the patients (78.3％ in the diabetes mellitus group, and 36.1％ in the non-diabetes mellitus group, P<0.01). Fasting glucose, HbA1c and 28-day mortality were improved more significantly (P<0.01) in the drug therapy subgroup than in the non-drug therapy subgroup. The 28-day mortality was more significantly different in patients with fasting blood glucose >8.33 mmol/L than in those with fasting blood glucose <8.33 mmol/L.CONCLUSIONS:Hyperglycemia of critically ill patients could not totally attribute to stress response, especially in those who have no history of diabetes mellitus. Prognosis of hyperglycemia may vary among critically ill patients.

This review introduced the anti-tumor effects of non-steroid anti-inflammatory drugs (NSAIDs) and summarized their possible molecular mechanisms according to recent abroad literatures and our research results. Some evidence showed that the anti-tumor mechanisms of NSAIDs were different in various tumors.NSAIDs decreased the biosynthesis of PGE_2 and regulated the expressions of downstream correlated genes and proteins through restraining abnormal expression of COX-2 in certain neoplasms,which resulted in the inhibition of tumor angiogenesis and proliferation as well as induced apoptosis. But in other cancer cells, NSAIDs, as activators of peroxisome proliferator-activated receptor ? (PPAR?), induced COX-2 expression, promoted the biosynthesis of cyclopentenone prostaglandins (cyPGs). cyPGs further induced tumor cell apoptosis with PPAR? dependently or PPAR? independently. Since their special mechanisms of anti-proliferation and pro-apoptosis, NSAIDs revealed significant synergistic effects with other anti-tumor treatments.

Objective To analyze the change in infrared(IR)spectral information and to screen out the classification of major compounds affecting information difference in IR spectra of Trichosanthes before and after steaming. Methods The similarity between the original IR fingerprint and the first derivative IR fingerprint of Trichosanthes and their steamed products was calculated by using the Computer Aided Similarity Evaluation System. The principal component analysis(PCA)model and the partial least squares dis-criminant analysis(PLS-DA)model of IR spectral data of Trichosanthes before and after steaming were established by using SIMCA-P 11 statistical software for PCA and PLS-DA,and the classification of major compounds affecting information difference in IR spectra of Trichosanthes before and after steaming was selected by 3D scatter plot,load 3D scatter plot and variable important in project(VIP) value. Results The similarity between the original IR fingerprint and first derivative IR fingerprint of Trichosanthes and their steamed products were 0.9165 and 0.2832. Seven VIP>1 spectral peaks were screened out by using SIMCA-P 11 statistical software,of which,the absorption peak of 1456 cm-1 was νc=c,the absorption peak of 1726 cm-1 was νc=o and the VIP values were 1.6290 and 1.4256 respectively. Conclusion The categories of compounds of Trichosanthes before and after steaming did not change,but the chemical components changed. Compounds of Trichosanthes before and after steaming affect the difference in IR spectral information may mainly contain C=C-C=C or C=O or both of them.
