Abstract
Objective: To understand the incidence and causes of HIV/AIDS death patients in Taizhou from 1998 to 2022. Methods: The data were collected from the AIDS Integrated Prevention and Control Information System of China Information System for Diseases Control and Prevention and Taizhou Chronic Disease Information Management System. By the end of 2022, a total of 5 126 HIV/AIDS patients living in Taizhou for a long time were included, SAS 9.4 was used for Kruskal-Wallis test, χ2 test and trend analysis. Results: From 1998 to 2022, a total of 796 HIV/AIDS patients died, with a fatality rate of 15.53% (796/5 126), in whom 52.26% (416/796) died within one year after confirmation. The proportion of HIV/AIDS patients who died within one year decreased (trend χ2=5.60, P<0.001). For the constituent of death causes, there were 140 (17.59%) deaths of AIDS, 237 (29.77%) deaths of malignant tumors, 99 (12.44%) deaths of cardiovascular disease, 58 (7.29%) deaths caused by injuries, 160 (20.10%) deaths due to other causes, and 102 (12.81%) deaths due to unknown causes. The constituent ratio of deaths of malignant tumor, cardiovascular disease and other causes increased over time (trend χ2=1.92, P=0.028; trend χ2=2.81, P=0.003; trend χ2=2.07, P=0.020). There were differences in the distribution of death causes in HIV/AIDS cases in terms of age, occupation, marital status, ethnic group, educational level and mode of transmission (all P<0.05). The average age of the death cases due to cardiovascular disease was higher than other death cases, the cases who died from AIDS had shorter survival time and the lower initial CD4+T cells after confirmation compared with all other death cases, and the time interval from confirmation to treatment in HIV/AIDS patients with unknown death causes was longer than those of all other death cases (all P<0.05). Conclusions: The constituent ratio of non-AIDS related deaths in HIV/AIDS patients in Taizhou was relatively high and showed an upward trend during 1998-2022. It is necessary to further strengthen the early screening, prevention and treatment of chronic non infectious diseases.

Abstract
Objective: Using two measuring tools to examine the prevalence and correlates of neurocognitive impairment (NCI) as well as characteristics of neurocognitive performance among people with HIV (PWH) on antiretroviral treatment (ART). Methods: A total of 2 250 treated PWH from the Comparative HIV and Aging Research in Taizhou (CHART) were recruited in Taizhou, Zhejiang province. The Chinese version of the Mini-mental State Examination (MMSE) and the International HIV Dementia Scale (IHDS) were used to evaluate their neurocognitive performance. Cluster analysis was conducted on the seven cognitive domains in the scale. Results: Among 2 250 treated PWH, 48.0% (1 080/2 250) were aged 45 to 89, 79.2% (1 782/2 250) were male, and 37.8% (852/2 250) had primary school education or below. The prevalence of neurocognitive impairment judged by MMSE and IHDS among HIV-infected people was 14.3% (321/2 250) and 31.8% (716/2 250), respectively. Aged 60 to 89 (aOR=2.63, 95%CI:1.52-4.56), depressive symptoms (aOR=5.58, 95%CI:4.20-7.40) and treatment with EFV (aOR=2.86, 95%CI:1.89-4.34) were main risk factors of NCI diagnosed by MMSE. Male (aOR=0.71, 95%CI:0.51-1.00), overweight (aOR=0.63, 95%CI:0.44-0.89), and high education level (aOR=0.11, 95%CI:0.05-0.25) were protective factors of NCI diagnosed by MMSE. Aged 60 to 89 (aOR=3.10, 95%CI:2.09-4.59), depressive symptoms (aOR=1.78, 95%CI:1.44-2.20) and treatment with EFV (aOR=1.79, 95%CI:1.41-2.29) were risk factors of NCI diagnosed by IHDS. Male (aOR=0.75, 95%CI:0.58-0.97), underweight (aOR=0.67, 95%CI:0.47-0.96), baseline CD4+ T lymphocyte (CD4) counts ≥350 cells/μl (aOR=0.69, 95%CI:0.53-0.91) and high education level (aOR=0.23, 95%CI:0.14-0.39) were protective factors of NCI diagnosed by IHDS. The neurocognitive performance of HIV-infected people can be divided into four main types. Among four types, age, gender, education level, alcohol drinking, depressive symptoms, waist-to-hip ratio, hypertension, diabetes, baseline CD4 counts and treatment with EFV were different statistically (all P<0.05). Conclusions: There are four main types of neurocognitive performance in treated PWH. The prevalence of NCI is high among this population, underscoring the need for tailored prevention and intervention.

Abstract
Objective: To explore the correlation between club drug use and anal canal human papillomavirus (HPV) infection in HIV-negative and HIV-positive men who have sex with men (MSM) in Taizhou. Methods: A cross-sectional survey was conducted in Taizhou. HIV-negative MSM were recruited by convenient sampling in voluntary counseling and testing clinics of Taizhou prefectural CDC from August 2016 to October 2017, and HIV-positive MSM were recruited through the routine follow-up and management by Taizhou prefectural CDC from August 2016 to June 2019. A face-to-face questionnaire interview was conducted to collect the information about the socio-demographic characteristics, sexual orientation, sexual behavior, club drug use and other information of the participants. Anal canal swabs were collected for HPV genotyping. The correlation between club drug use and the prevalence of HPV infection were evaluated with χ2 test and logistic regression analysis. Results: A total of 69 HIV-negative and 345 HIV-infected MSM were included. The prevalence of any type of anal canal HPV infection in HIV-negative MSM (27.5%, 19/69) was lower than that in HIV-positive MSM (66.4%, 229/345) (χ2=36.114,P<0.001). The prevalence of self-reported club drug use in HIV-negative MSM was higher (17.4%, 12/69) than that in HIV-positive MSM (7.0%, 24/345) (χ2=7.886, P=0.005). For HIV-negative MSM, the prevalence of club drug use was higher in MSM who had homosexual group sex (P=0.036); the prevalence of HPV infection was 50.0% (6/12) in club drug users and 22.8% (13/57) in non-club drug users (χ2=3.674, P=0.055). For HIV-positive MSM, the prevalence of HPV infection was 70.8% (17/24) in club drug users and 66.0% (212/321) in non-club drug users (χ2=0.230, P=0.632). Multivariable logistic regression model showed that HPV infection in MSM was positively correlated with HIV infection (OR=5.42, 95%CI: 2.92-10.06), and the association between HPV infection and club drug use (OR=1.66, 95%CI: 0.75-3.71) was not significant. Conclusions: HIV infection was positively correlated with anal canal HPV infection in MSM in Taizhou. Club drug use was positively correlated with high-risk sexual behaviors, while its association with HPV infection needs further study.

Abstract
Objective: To explore the HIV-1 drug resistance and subtypes in newly reported HIV/AIDS patients before antiretroviral therapy (ART) in Taizhou city. Methods: A cross-sectional study of HIV-1 drug resistance was conducted among newly reported HIV/AIDS patients before ART in Taizhou from January 2016 to December 2018. HIV-1 pol gene sequences were obtained by RT-PCR. The sequences were submitted to the Stanford University drug resistance database. The drug resistance mutation and the sensitivity of HIV-1 strains to antiretroviral drugs were determined according to WHO Guidelines on HIV drug resistance surveillance of 2014. Results: A total of 806 HIV-1 pol gene sequences were obtained successfully. The overall HIV-1 drug resistance rate was 2.9% (23/806), 1.9% for non-nucleoside reverse transcriptase inhibitors (NNRTIs), 0.6% for nucleoside reverse transcriptase inhibitors (NRTIs), and 0.0% for protease inhibitors (PIs), respectively. From 2016 to 2018, the HIV-1 drug resistance rate was 1.6%, 1.8%, and 4.8%, respectively. The resistance mutations of NNRTIs and NRTIs were mainly K103 N (0.7%) and M184I/V (0.5%). HIV-1 subtypes were mostly CRF01_AE (42.7%,344/806),CRF07_BC (28.9%,233/806) and CRF08_BC (11.2%,90/806).HIV-1 subtypes among homosexually transmitted infections were mostly CRF01_AE (53.3%, 136/255) and CRF07_BC (32.2%, 82/255), and HIV-1 subtypes among heterosexually transmitted infections were mainly CRF01_AE (37.7%, 203/539), CRF07_BC (27.5%, 148/539) and CRF08_BC (16.1%, 87/539). Conclusion: HIV-1 drug resistance rate among newly reported HIV/AIDS patients before ART remained low in Taizhou during 2016 to 2018, an increasing trend seemed to be notifiable and warrants continuous surveillance of HIV-1 drug resistance.

Abstract
Objective: To study the prevalence and correlates of plasma cytomegalovirus (CMV) viremia among newly reported antiretroviral therapy (ART)-naive HIV/AIDS patients in Taizhou during 2017-2018. Methods: CMV DNA was measured in plasma specimens of newly reported ART-naive HIV/AIDS patients by quantitative PCR. Both univariable and multivariable logistic regression analyses were carried out to evaluate CMV viremia correlations among the individuals. Results: Of 612 HIV/AIDS patients, 480 (78.4%) were male, 125 (20.4%) were over 60 years old, 177 (28.9%) were infected via homosexual transmission, and 430 (70.3%) via heterosexual transmission. The prevalence of CMV viremia among HIV/AIDS patients was 13.4% (82/612). Multivariable logistic regression analysis showed that the risk of CMV viremia in CD4+ lymphocyte cells counts (CD4+) ≤200 cells/μl group was higher than CD4 counts >500 cells/μl (OR=5.10, 95%CI:1.74-14.96, P=0.003); The median CMV DNA level (log10) of 82 viremic patients was 1.57 (P25,P75:1.04,2.13); Viremic patients with CD4 counts ≤200 cells/μl had the highest CMV viral load (P<0.01). Conclusions: Among ART-naive HIV/AIDS patients, the prevalence of CMV viremia was significantly associated with immunodeficiency status. Further research is needed to evaluate the association between CMV viremia and the course of HIV infection.

Abstract
Objective: To analyze influencing factors of instant antiretroviral therapy (ART) and explore associution between strategies of ART and immunological effects among HIV/AIDS patients in Taizhou city during 2006-2019. Methods: A retrospective cohort study was conducted on HIV/AIDS patients under ART, and a logistic regression model was used to analyze factors of instant ART. The student t-test and chi-square test were used to compare immunological effect of different ART strategies while the Kaplan-Meier method was used to generate a survival curve. Results: A total of 2 971 HIV/AIDS patients were enrolled with 1 786 cases (60.1%) having instant ART strategy. The proportion of instant ART were 77.8% (1 170/1 504) during 2016 to 2019. The treatment success rate of the instant ART group (87.4%, 1 561/1 786) were higher than the delayed ART group (84.4%, 1 000/1 185). The results of multivariate logistic regression model indicated that male (aOR=1.28, 95%CI: 1.03-1.59), married (aOR=1.71, 95%CI: 1.33-2.19) and baseline CD(4)(+)T lymphocyte cells (CD(4)) counts ≤200 cells/μl (aOR=1.60, 95%CI: 1.27-2.02) were factors positively related to instant ART while 31-40 years old (aOR=0.63, 95%CI: 0.48-0.84), infected through heterosexual transmission(aOR=0.60, 95%CI: 0.49-0.74) and diagnosed before 2015 (aOR=0.20, 95%CI: 0.17-0.23) were inversely related to instant ART. The increase of the CD(4)/CD(8) ratio was greater, and the cumulative ART success rate was higher each year in the instant ART group than in the delayed ART group (P<0.05). Conclusions: The instant ART strategy has been well implemented in Taizhou city during 2006-2019, and the immunological effect was better in instant ART group. The proportion of instant ART were more than 60.0% among HIV/AIDS patients. Instant ART strategy needs to be strengthened for those who are 31-40 years old, women, unmarried, and infected through heterosexual transmission in an attempt to further increase treatment level and improve treatment effect.

Abstract
Objective: To analyze the immunological failure of antiretroviral therapy (ART), its association with baseline anemia and related factors in HIV/AIDS patients in Taizhou prefecture, during 2006-2019. Methods: A retrospective cohort study was conducted among HIV/AIDS patients under ART. Cox regression model was used to analyze predictors of immunological failure and logistic regression model was used to analyze factors of baseline anemia. Results: A total of 2 904 HIV/AIDS patients were enrolled with a median time of 28 (P(25)-P(75):12-53) months follow-up of ART, in which 177 cases (6.1%) were identified as immunological failure with a failure rate of 2.17 per 100 person-years. The cumulative incidence rates of immunological failure in the first, third, fifth, and tenth years were 5.49%, 6.94%, 7.30% and 8.82%, respectively. Results of multivariate logistic regression analysis showed that for the risk of baseline anemia, ≥66 years old group had 4.17 times higher risk than 18-25 years old group (95%CI: 1.68-10.33), males had 0.67 times higher risk than females (95%CI: 0.50-0.89), and CD(4)(+)T cell counts (CD(4))<200 cells/μl group had 4.35 times higher risk than CD(4)≥350 cells/μl group (95%CI: 2.81-6.72), baseline white blood cells<4.0×10(9) cells/L group had 1.73 times higher risk than 4.0×10(9) cells/L-9.9×10(9) cells/L group (95%CI: 1.31-2.29), baseline platelet counts <100×10(9) cells/L and >300×10(9) cells/L groups had 2.02 times and 4.45 times higher risk than 100×10(9) cells/L-299×10(9) cells/L group (95%CI: 1.36-3.01, 95%CI: 3.05-6.50), respectively. WHO classified stage Ⅲ/Ⅳ group had 2.15 times higher risk than WHO classified stageⅠ/Ⅱ group (95%CI: 1.61-2.87), while heterosexual transmission group had 2.03 times higher risk than homosexual transmission group (95%CI: 1.42-2.92). Results of multivariate cox proportional risk regression showed that for the risk of immunological failure, baseline anemia group had 1.77 times higher risk than no anemia group (95%CI: 1.20-2.60), WHO classified stage Ⅲ/Ⅳ group had 1.66 times higher risk than WHO classified stage Ⅰ/Ⅱ group (95%CI: 1.10-2.48), and withdrawal of follow up and death groups had 3.18 times and 4.61 times higher risks than treatment group (95%CI: 1.96-5.19, 95%CI: 2.98-7.13), respectively. Conclusions: The immunological effect of ART among HIV/AIDS patients in Taizhou prefecture was affected by multiple factors, including anemia, clinical stage and follow-up status. Enhancing surveillance of baseline anemia and timely correction of anemia in elder group can help improve treatment outcome of HIV/AIDS patients.

Abstract
Objective: To understand the prevalence of alcohol use and related factors in HIV positive and HIV negative males. Methods: Baseline data were from the prospective cohort study of comparative HIV and aging research in Taizhou of Zhejiang province from January to December, 2017. The information about alcohol use in the last month was collected through a face-to-face questionnaire interview. Participants were categorized into non-current drinkers, light/moderate drinkers and heavy drinkers according to the US National Institute on Alcoholism and Alcohol Abuse (NIAAA) standard. Results: A total of 1 367 HIV positive males and 2 418 HIV negative males were included. Current alcohol use rate (35.2%, 481/1 367) and heavy alcohol use rate (5.0%, 24/481) were significantly lower in HIV positive males than in HIV negative males (48.0%, 1 161/2 418; 23.5%, 273/1 161), but the proportion of drinking wine and yellow rice wine were significantly higher (21.8%, 105/481; 9.1%, 44/481) in HIV positive males than in HIV negative males (13.5%, 157/1 161; 5.8%, 67/1 161). The multivariate multinomial logistic regression analysis results showed that larger waist circumference, current smoking and regular physical exercise were associated with heavy alcohol use behavior in HIV positive males, and age ≥30 years, current smoking, regular physical exercise, higher score of depressive symptoms, heterosexual transmission route and baseline CD(4)(+)T cells counts of 200-499 cells/μl were significantly associated with mild/moderate alcohol use behavior in HIV positive males. Conclusions: The alcohol use rate was significantly lower in HIV positive males than in HIV negative males in Taizhou. It is important to strengthen intervention on alcohol drinking behavior and chronic disease risk factors, such as larger waist circumference, smoking and so on.

Abstract
Objective: To understand the prevalence of group sex in men who have sex with men (MSM) and related factors in Taizhou, Zhejiang province. Methods: From March 2013 to September 2015, a cross-sectional survey was conducted among MSM recruited from gay bars or bath houses in Taizhou by using questionnaire to collect the information about their sexual behavior and HIV test. Results: A total of 1 435 MSM were recruited, 179 of them (12.5%) were HIV infected, 231 (16.1%) reported group sex during the past year. Compared with MSM without group sex, more MSM with group sex had more than ten male sexual partners (53.7% vs. 19.0%, χ(2)=125.527, P<0.01), had both male and female sexual partners (86.6% vs. 68.2%, χ(2)=31.935, P<0.01), used no condom at sex with female partners during the past year (28.1% vs. 19.8%, χ(2)=6.540, P<0.05). After adjusted for educational level and occupation, group sex was associated with age[≥50 years old vs. ≤24 years old, adjusted odds ratio (aOR)=2.25, P=0.027], marriage with female (divorced or widowedvs. unmarried, aOR=0.29, P=0.001), census registering (local resident vs. non-local resident, aOR=1.56, P=0.023), number of male seuxal partners (≥21 vs. 2-5, aOR=8.06, P<0.001; 11-20 vs. 2-5, aOR=3.25, P<0.001) and number of female seuxal partners (≥6 vs. 0, aOR=2.63, P=0.005; 2-5 vs. 0, aOR=2.58, P=0.001; 1 vs. 0, aOR=2.01, P=0.010). Conclusion: The prevalence of group sex in MSM was high in Taizhou, and their poor condom use and complex sex behaviors would result in higher HIV infection rate and risk of transmission.

Abstract
OBJECTIVE Pharmacotherapy of depression in children and adolescents is complex. In the absence of research into the efficacy and safety of antidepressants in this group of patients, their off-label prescription is common. This paper aimed to illustrate the prescription pattern of antidepressants in children and adolescents from major psychiatric centres in Asia. METHODS The Research on Asia Psychotropic Prescription Pattern on Antidepressants worked collaboratively in 2013 to study the prescription pattern of antidepressants in Asia using a unified research protocol and questionnaire. Forty psychiatric centres from 10 Asian countries / regions participated and 2321 antidepressant prescriptions were analysed. RESULTS A total of 4.7% antidepressant prescriptions were for children and adolescents. Fluoxetine, sertraline, and escitalopram were the most common antidepressants prescribed for children and adolescents. Almost one-third (30.3%) of prescriptions were for diagnoses other than depressive and anxiety disorders. There was less antidepressant polypharmacy and concomitant use of benzodiazepine, but more concomitant use of antipsychotics in children and adolescents compared with adults. CONCLUSION Off-label use of antidepressants in children and adolescents was reported by 40 Asian psychiatric institutions that participated in the study. In-service education and regulatory mechanisms should be reinforced to ensure efficacy and safety of antidepressants in children and adolescents.

Abstract
OBJECTIVE To evaluate the prescription pattern of antidepressants in patients with medical co-morbidity from major psychiatric centres in Asia. METHODS The Research on Asian Psychotropic Prescription Pattern for Antidepressants (REAP-AD 2013) collected data from 42 psychiatric centres in 10 Asian countries and regions. Antidepressant prescriptions of 2320 patients with various psychiatric disorders were evaluated. Of these, 370 patients who had specified medical co-morbidities formed the study cohort. RESULTS Escitalopram (20%) and mirtazapine (20%) were the most commonly prescribed antidepressants in patients with medical co-morbidity followed by sertraline (16%), trazodone (15%), and paroxetine (12%). Overall, more than half (52%; 247/476) of prescriptions comprised selective serotonin reuptake inhibitors. Slightly less than two-thirds (63%; n = 233) of patients received at least 1 selective serotonin reuptake inhibitor. In addition, 79% of patients were prescribed only 1 antidepressant. The mean number of antidepressants used per patient was 1.25 (standard deviation, 0.56). There were subtle differences in the most preferred antidepressant across medical illnesses such as diabetes mellitus, liver dysfunction, acid peptic disease, and cerebrovascular disease. Differences were also seen in prescription patterns across different countries. CONCLUSION Although selective serotonin reuptake inhibitors formed the bulk of antidepressant prescriptions in the presence of medical co-morbidity, mirtazapine was also commonly used in the presence of medical co-morbidities. Specified medical morbidities do influence the selection of antidepressants.

Abstract
OBJECTIVE To investigate the effects of liposomal formulation on simvastatin nano-liposomes (SMV-liposome) promoting the osteogenic differentiation of mice bone marrow stromal cells (BMSC) analyzed by the expressions of bone morphogenetic protein 2 (BMP-2) and alkaline phosphatase (ALP). METHODS Primary BMDC were cultured in vitro using adherence and culture of whole bone marrow method. SMV dosage was set as control group and had two different dosages in this group on the basis of the concentration of SMV. 1 μmol/L and 2 μmol/L SMV concentration were represented by SMV low dosage group (S1) and SMV high dosage group (S2), respectively. Similarly, SMV-liposome dosage was set as experimental group including two different dosages, 1 μmol/L SMV capsuled concentration as SMV-liposome low dosage group (SL1) and 2 μmol/L SMV capsuled concentration as SMV-liposome high dosage group (SL2). Besides, groups with no drug intervention in the experiments were set as blank. BMSC were treated with different concentrations of SMV and SMV-liposome for 48 h, the activity of ALP was measured using p-nitropheny-phosate method, and ALP expression in the BMSC cells was stained by BCIP/NBT alkaline phosphatase color development kit (BCIP/NBT Kit). Furthermore, BMP-2 expression in the BMSC was determined by Western Blot. RESULTS MTT assay showed, after incubated with different concentrations of SMV and SMV-liposome, the cell viabilities of BMSC were all above 85% and had no significant difference in the groups. Compared with the same dosage of SMV in these groups, control group and experimental group had significantly elevated the specific activity of ALP, the staining of BCIP/NBTKit as well as the protein expression of BMP-2. Besides, the data showed dose-dependent elevation in the control group and experimental group, namely the high dose group had better results than the low dose group. CONCLUSION Nano-liposomal formulation significantly enhanced SMV effects on the osteogenetic differentiation of BMSC.

Abstract
UNLABELLED Anion exchanger 2 (AE2), which mediates exchange of Cl(-)/HCO3(-) across the plasma membrane, is widely expressed in body tissues. It is most abundantly expressed in stomach and is responsible for the uptake of Cl(-) ions that are destined to become HCl molecules. AIM To determine whether AE2 expression was altered in gastric tumors. METHODS We have studied AE2 expression in normal human gastric tissues (n =16) and in gastric tumors (n = 33) using immunohistochemistry and immunofluorescent labeling. RESULTS In normal gastric tissue positive staining was observed in gastric fundus gland, suggesting parietal cell-related expression of AE2, and AE2 expression was localized in the nuclear membrane and even in cell nuclei. For assay of cancerous gastric tissues, specimens of human gastric cancer arising from the region of the fundus (2 cases), the body (14 cases) and the antrum (17 cases) were randomly selected. Immunohistochemical staining has showed that AE2 was down-regulated in all 14 cancerous gastric body specimens, whereas staining for AE2 in cancerous antrum was less intense and had a diffuse profile. CONCLUSIONS The data suggest that AE2 might be associated with gastric carcinogenesis and the achlorhydria experienced by gastric cancer patients.

Abstract
Solid-supported lipid membranes are important for their roles in fundamental biophysical research as well as in applications such as biosensors. In our study, lipopolymers containing alkyl side chains were synthesized and a mixture of the lipopolymer and free lipids was preorganized at the air-water interface and then transferred to a solid substrate using the Langmuir-Blodgett technique. A photochemical reaction between a substrate-functionalized benzophenone and C-H bonds on the lipopolymer was used to attach the lipopolymers to the substrate. The final assembly of the membrane was completed by vesicle fusion. Langmuir film experiments at the air-water interface indicate tighter molecular packing for the lipopolymers with 28 mol % alkyl side chains than for the ones with 22 mol %. Atomic force microscopy images point to phase separation of lipopolymers on the substrates due to their dewetting from hydrophobic surfaces. However, a mixture of lipopolymers and free lipids formed a smooth film on the same substrate. After the addition of the second lipid layer on the lipopolymer/free lipid layer, the fluorescence images of the polymer-supported bilayer suggested that the distal lipid layer is homogeneous on the micrometer scale. The relaxation of the fluorescent probe lipids was analyzed after application of an electric field to determine their diffusion coefficient; the distal lipid layer was mobile with an average diffusion coefficient of approximately 0.1 microm(2)/s. Moreover, the immobile fraction of the lipids in the distal layer was estimated to be around 15%.

Abstract
The Chinese version of the Davidson Trauma Scale (DTS-C) was developed to respond to the need of Chinese-speaking individuals. The DTS is a validated self-rating scale used in the diagnosis of posttraumatic stress disorder (PTSD). The DTS-C is translated from DTS through a two-stage translation. Subjects were drawn from a sample of 210 survivors of the 21 September 1999, Chi-Chi Earthquake. The scale showed good internal consistency (Cronbach's alpha = 0.97) and test-retest reliability (r = 0.88). Concurrent validity was obtained against the clinical diagnostic interview, with a diagnostic accuracy of 0.85 at DTS-C score of 44. It showed that the sensitivity was 0.9, specificity 0.81, positive likelihood ratio 4.74, and negative likelihood ratio 0.12. The recommended stratum-specific likelihood ratios were 0.10 (95% CI: 0.05-0.20) for the score range 0-39, 4 (2.22-7.23) for the score range of 40-59, and 6.14 (3.42-11.02) for the scores above 60. In PTSD diagnosed subjects, the factor structures closely resembled the DSM-IV grouping of PTSD symptoms. The psychometric strength of DTS-C is reliable for its future use, particularly for screening for subjects with possible diagnosis of PTSD.

Abstract
Because of the potential adverse events and teratogenesis of antipsychotic drugs, it is important to find a safe and effective treatment for pregnant women with severe mental illness. The membrane hypothesis of schizophrenia provides a rationale to treat symptoms of schizophrenia with omega-3 PUFAs. We report a 30-year-old married woman with chronic schizophrenia, who experienced an episode of acute exacerbation of psychotic symptoms during pregnancy. After entering into an open trial of omega-3 PUFAs monotherapy, she showed a dramatic improvement in both positive and negative symptoms of schizophrenia and a significant increase of omega-3 PUFA composition in erythrocyte membrane. There were no adverse effects in this treatment. Thus, omega-3 PUFAs could be both beneficial and therapeutic to pregnant schizophrenic women.

Abstract
Delusions associated with cerebrovascular diseases have been sporadically reported. Although both psychiatrists and neurologists attempted to link delusions with anatomical locations of the brain lesion, comorbid psychiatric and neurological disorders make the interpretation of delusions difficult. The purpose of the present paper is to report the clinical features and magnetic resonance imaging (MRI) characteristics in patients with delusional disorder due to diffuse cerebrovascular diseases, and to redefine the concept of 'vascular delusion'. The clinical features and MRI findings were reviewed retrospectively in a series of seven patients with 'delusional disorder due to cerebrovascular disease' as defined in Diagnostic and Statistical Manual of Mental Disorders (DSMIV). The average age of onset is 64. No patient had a prior personal or family history of major psychiatric illness. The illness is presented as acute, subacute or stepwise course. Hypertension was present in all patients. Two had diabetes mellitus, and one had atrial fibrillation. Three had clinical evidence of previous cerebrovascular attacks, only one showed minor neurological deficits. Three had diffuse cortical slow wave in electroencephalogram. No patient had significant cognitive impairment but had multiple cortical and subcortical cerebrovascular lesions in MRI, with white-matter lesions (WML) in bilateral frontal areas. Delusional disorder due to diffuse cerebrovascular change is characterized by late-onset, stepwise course, and comorbid medical and neurological diseases. The results of vascular changes in the present study did not establish a cause-effect relationship and should be considered as multifactorial in pathogenesis. The findings suggested the hypothesis of neural circuit theory. Further studies in larger numbers of patients and newer neuroimaging techniques are needed to expand the knowledge learned from these findings.

Abstract
OBJECTIVE To investigate isoflavone supplementation on plasma lipids, erythrocyte antioxidant enzyme activities and bone mineral density in postmenopausal women. STUDY DESIGN Thirty-seven postmenopausal women were given 150 mg/d of isoflavone supplements twice daily for six months. Blood was sampled before and after supplementation, at three and six months. RESULTS There were no significant differences in plasma total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglyceride concentrations or erythrocyte antioxidant enzyme activities after three and six months of supplementation when compared with the baseline. No significant changes were noted in calcaneus bone mineral density after supplementing isoflavones for six months. CONCLUSION The antioxidant effect of isoflavones in normal postmenopausal women is not obvious, and supplementation with isoflavone alone may not have a hypocholesterolemic effect. Since the duration of this study was too short with respect to bone density, longer studies are needed to clarify the bone-sparing effect of isoflavone supplementation.

Abstract
Our strategy to provide the structural basis for the build-up of functional tethered membranes focuses on three approaches: the first one is based on the pre-organization of a monomolecular layer of a lipopolymer at the water/air interface which is then transferred to a solid support. Prior to deposition, the substrate is coated with a layer of benzophenone-derivatized silane molecules that allow for a stable covalent attachment by photo-cross-linking of some of the monomer units of the lipopolymer to the support. An alternative concept realizes a layer-by-layer deposition of the various structural elements: (1) the attachment layer with the reactive sites for the chemical stabilization; (2) a polymer 'cushion' prepared by adsorption and simultaneous or subsequent partial covalent binding to the reactive sites; and (3) a lipid monolayer transferred from the water/air interface, that contains a certain amount of lipids with reactive headgroups which, upon binding to the polymer tether, act as anchor lipids stabilizing the whole monolayer/cushion-composite. And finally, we build peptide-supported monolayers by first (self-) assembling amino acid sequences of various lengths via a SH-group near their N-terminus onto Au substances and use then their COO(-)-terminus to chemically attach phosphatidyl-ethanolamine lipids to form a stable monolayer of lipid-peptide conjugates. All the individual preparation steps and the various resulting (multi-) layers are characterized by surface plasmon spectroscopy, X-ray and neutron-reflectometry, contact angle measurements, IR spectroscopy, fluorescence microscopy, scanning probe microscopies, as well as, electrochemical techniques. For all tethering systems, the final membranes' architecture is obtained by fusing lipid vesicles onto the lipid monolayer. Proteins can be incorporated by either fusing vesicles that are loaded with the respective receptors, pores, or ion pumps via a reconstitution procedure, or via a transfer directly from a micellar solution to the pre-formed lipid bilayer at the solid support by a dialysis step. Two structural/dynamical features of tethered membranes which are considered to be of particular functional relevance, i.e. the degree of water uptake and, hence, the degree of swelling of the polymer support, as well as the lateral mobility of the lipid molecules in the membrane, are tested by surface plasmon optics and by measurements of the fluorescence recovery after photobleaching (FRAP), respectively. The results confirm that the presented preparation protocols yield fluid bilayers that mimic certain relevant properties of biological membranes. The functional characterization of tethered membranes, which is briefly summarized, is based on various electrochemical techniques, in particular, impedance spectroscopy, cyclic voltammetry, and chronoamperometric studies. The results obtained for reconstituted H(+)-ATPase from chloroplasts and E. coli and for cytochrome oxidase (with and without cytochrome c) confirm the incorporation of the proteins in an active form, thus, opening opportunities for novel sensor formats or offering a completely new model membrane system.

Abstract
Several reports have noted cases of OCD which were unusual in showing an abrupt remission. We report longitudinal clinical observation of four cases of acute onset OCD without major depression through a variety of treatments. These patients had prominent feelings of shamefulness; compared to patients with typical OCD they were ill for months rather than years and were older. Two had previous episodes of psychiatric illness with full recovery. Full and persistent recovery occurred in response to lithium or an acute course of ECT but not to tricyclic or SSRI antidepressants. The generalizability of these observations is limited by its uncontrolled nature and the small numbers. The courses observed were consistent with episodic OCD as a possible expression of bipolar disorder and consideration of corresponding treatments. This perspective offers a new rationale for reported observations of remissions of acute onset OCD in response to lithium without lithium effectiveness for typical OCD.

Abstract
The history of antipsychotic drug development has had a long and torturous course, often based on chance findings that bear little relationship to the intellectual background driving observations. In 1891, Paul Ehrlich observed the antimalarial effects of methylene blue, a phenothiazine derivative. Later, the phenothiazines were developed for their antihistaminergic properties. In 1951, Laborit and Huguenard administered the aliphatic phenothiazine, chlorpromazine, to patients for its potential anesthetic effects during surgery. Shortly thereafter, Hamon et al. and Delay et al. extended the use of this treatment in psychiatric patients and serendipitously uncovered its antipsychotic activity. Between 1954 and 1975, about 15 antipsychotic drugs were introduced in the United States and about 40 throughout the world. Thereafter, there was a hiatus in the development of antipsychotics until the introduction of clozapine treatment in the United States in 1990 opened the era of "atypical" antipsychotic drugs, which show a reduced potential to induce extrapyramidal symptoms (EPS), an increased efficacy for the negative symptoms of schizophrenia, no elevation of prolactin after chronic use (except risperidone), and, at least for clozapine, effectiveness in some patients previously regarded as treatment-refractory. This review describes the available atypical antipsychotic drugs and their characteristics, and concludes by highlighting those in the pharmaceutical "pipeline."

Abstract
This paper reviews the current literature describing the metabolism of both multi-receptor clozapine analogue atypical antipsychotic drugs (clozapine, olanzapine, and quetiapine) and serotonin-dopamine antagonist atypical antipsychotic drugs (risperidone, sertindole and ziprasidone), to highlight the significance of those data in the context of clinical practice. The former group of atypical antipsychotic drugs shares a similar tricyclic structural nucleus and are metabolized through three major categorical metabolic pathways--N+-oxidation, N-glucuronidation, and phases 1 and 2 biotransformation with final glucuronidation before renal excretion. Differing in clozapine and olanzapine, quetiapine has incomplete data describing its metabolism. The latter group of atypical antipsychotic drugs has diversified chemical structures and absence of data on N+-oxidation and N-glucuronidation in the literature. But their metabolic routes in phase 1 biotransformation are versatile although current data are far from completion. No apparent significant drug interactions in clinical practice are reported, although QT prolongation is implicated in all those three drugs. None of all six atypical antipsychotic drugs are identified as significant inhibitors or inducers to any co-administered medication. The author suggests the need for more research to address some pertinent clinical issues in the metabolism of those drugs.

Abstract
OBJECTIVE To review the literature describing female orgasmic disorder and impaired sexual desire disorder by selective serotonin reuptake inhibitors (SSRIs) and their treatment, including the use of sildenafil. STUDY DESIGN Literature reviews of all available published articles on this topic from 1989 to 1996 were done. This paper also includes a sample case of a 38-year old woman who suffers from fluoxetine-induced arousal and orgasmic disturbance. RESULTS Treatment approaches include the use of "antidotes," such as cyproheptadine, yohimbine, amantadine, granisetron and ginkgo biloba. This article also reports a case of successful female use of sildenafil, which was released by the Food and Drug Administration in March 1998 for erectile dysfunction in men. CONCLUSION Sildenafil is beneficial in reversing female sexual dysfunction induced by SSRIs. This paper also discusses sildenafil's action in the background of nitric oxide and cyclic guaninosine monophosphate in penile/clitoral erection.

Abstract
The human sexual response can be divided into 3 phases: desire (libido), excitement (arousal) and orgasm. The fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) classifies sexual disorders into 4 categories: (i) primary; (ii) general medical condition-related; (iii) substance-induced; and (iv) 'not otherwise specified' sexual dysfunctions. Each of the 4 DSM-IV categories has disorders in all 3 sexual phases. Substance-induced sexual dysfunctions are caused by the use of either substances of abuse [alcohol (ethanol), amphetamines, cocaine, opioids or sedatives/hypnotics/anxiolytics], or prescription medications which include psychotropic drugs. Patients with psychiatric difficulties tend to experience more frequent sexual function disturbances. The literature provides more than anecdotal evidence that psychotropic drugs can induce sexual function disorders in the epidemiologically vulnerable population of psychiatric patients. Sexual dysfunctions caused by psychotropic drugs can be divided into 2 groups: sexual inhibition (inhibited desire, inhibited arousal and inhibited orgasm) and increased sexual function disorders (increased sexual desire, priapism and premature ejaculation). The diagnosis of psychotropic drug-induced sexual function disorders is easy if the psychiatrist is sensitive to the existence of these adverse effects. This mostly involves careful history taking, although several questionnaires have been developed for reliable and valid quantification of sexual functioning. Diagnosis is usually established if the sexual function disorders develop when the patient is receiving a psychotropic drug and then disappear when the offending drug is discontinued. The management of psychotropic-drug induced sexual inhibition can be divided into 6 steps: inform the patient about the possibility of sexual inhibition occurring before prescribing a psychotropic agent; wait for remission or tolerance of sexual inhibition; reduce the dosage of the psychotropic drug; switch the medication to one less likely to cause sexual inhibition; if possible, adjust the concomitant nonpsychotropic drugs; and add various pharmacological agents to the existing psychotropic drug to treat the sexual inhibition. Physicians should take sexual histories as a routine practice when prescribing psychotropic drugs. Through careful management and patience on the part of both the patient and the physician, psychotropic drug-induced sexual function disorders can be improved so that the patient's compliance with medication and quality of life can be optimised.

Abstract
To determine the status of the tumor necrosis factor-alpha (TNFalpha) system in the liver in chronic hepatitis B virus (HBV) infection, hepatic expression of TNFalpha, its two receptors (TNFR-A, TNFR-B), HLA class I antigens (HLA-I), and HBV core antigen (HBcAg) were studied by immunohistochemistry in 24 patients with chronic HBV infection. TNFalpha was detected exclusively in the infiltrating mononuclear cells (MNC) in 19 of 24 patients. The expression of TNFalpha in infiltrating MNC correlated with serum markers of HBV replication and liver histology. TNFR were detected in hepatocytes, sinusoidal cells, and infiltrating MNC. The expression of TNFR correlated with liver histology (p < 0.01) but had no bearing on viral replication. There was a parallel expression of TNFalpha and TNFR (p < 0.01). Hepatocytic expression of HLA-I was increased, and this was related to liver histology but not with TNF alpha nor TNFR. These data indicate that the TNFalpha system is activated in the liver in chronic HBV infection.

Abstract
OBJECTIVE This is a retrospective study to add to the existing body of clinical information regarding male sexual side effects associated with antidepressants. From the chart review, thirty-four out of eighty male patients were identified to have reported loss of libido, erectile difficulty, anorgasmia, and delayed ejaculation while receiving pharmacotherapy of selective serotonin reuptake blockers (fluoxetine, paroxetine, and sertraline); tricyclic antidepressants (nortriptyline, imipramine, amitriptyline, desipramine, and clomipramine); and a monoamine oxidase inhibitor (phenelzine). METHOD The authors also discussed the management of these sexual side effects by waiting for spontaneous remission, reducing the dosage level, and substituting the offending drug with other antidepressants. RESULTS This article underscores the underreported nature of antidepressant-associated sexual dysfunction, the high incidence of SSRI-associated sexual side effects, equal potentials in causing sexual side effects among the three SSRI's, the low incidence rate of sexual adverse effects from bupropion, and the minimal need to add an antidote if the side effects are to be managed systematically. CONCLUSIONS Finally, male sexual side effects can occur randomly and involve any sexual phase randomly, and the treatment approaches are similar, regardless of the types of sexual dysfunction associated with antidepressants.

Abstract
OBJECTIVE After the advent of selective serotonin reuptake inhibitors on the U.S. market in 1988, American psychiatrists have been faced with more choices of antidepressants for the treatment of depression. The prescribing of SSRIs has been increasing in popularity because they are easily titrated by the physicians and tolerated by patients. However, the SSRI use is frequently associated with female sexual dysfunction. The aim of this study was to describe these SSRI-associated female sexual side effects. METHODS In a retrospective series, clinic records of 110 female SSRI-treated outpatients were reviewed for loss of or decreased libido, orgasmic disturbances (anorgasmia or delayed orgasm), as well as clinical management patterns to alleviate sexual side effects. RESULTS Twenty-one fluoxetine-, nine paroxetine-, and five sertraline-treated cases with female sexual inhibition were identified. The fates of SSRI-associated sexual adverse effects and clinical managements of restoring these side effects were described. CONCLUSIONS With some limitations in interpreting the data, the findings of this study suggest that SSRI-associated female sexual dysfunction occurs at a higher rate than we previously thought, equal potentials in implicating female sexual side effects among three SSRIs, and the absence or the low incidence of female sexual adverse effects from bupropion, and that these side effects can be managed by waiting for a spontaneous remission, dosage reduction of SSRIs, substitution with bupropion and other antidepressants, or the use of an antidote.

Abstract
OBJECTIVE This article is a five-year update on a previous review article (International Journal of Psychiatry in Medicine, 21:47-56, 1991) on cytochrome P450 monooxygenases and interactions of psychotropic drugs. METHOD In the literature review, the recent committee work on nomenclature of the P450 superfamily are highlighted. Then, the author reviewed gene clusters of three human cytochrome P450s--CYP1A2, CYP2D6, and CYP3A4 with the focus on the changes of serum levels of the coadministered psychotropic drugs in the context of enzymatic induction and inhibition of these three hepatic enzymes. RESULTS As indicated in one table, the author stratified probes, inducers, inhibitors, chemical reactions, and substrates under these three gene clusters. As shown in another simple table, the author compared the hepatic enzymatic inhibitions of four selective serotonin reuptake inhibitors and pointed out the inhibition potentials of fluvoxamine at CYP1A2, fluoxetine and paroxetine at CYP2D6, and fluoxetine and fluvoxamine at CYP3A4 if these two SSRIs have higher serum concentrations. CONCLUSION The author suggests that with these systematic approaches, this rapidly adding knowledge can help psychiatrists better understand psychotropic drug interactions and maximize the benefits of patients' psychopharmacotherapy.

Abstract
A clinical study of 25 male and 17 female schizophrenic suicides is presented. Jumping from a height was the most common method used. The 42 suicidal schizophrenics in Taiwan were compared with both 84 sex- and age-matched and 60 5-year illness course non-suicidal schizophrenic control groups. The suicidal schizophrenics were not significantly different from the non-suicidal counterparts of both control groups with regard to age, sex, ethnicity, religion, educational background, the presence of suicide cases in the family history, and the presence of insight, but were significantly different in characteristics of a history of previous suicide attempts, presence of psychotic symptoms during their final month, depression during their final month, a history of depression, a history of previous psychiatric hospitalizations, and the number of hospitalizations. We discuss the findings from this study and others in the literature in the context of the different clinical and socio-cultural backgrounds of these Taiwanese schizophrenic suicides.

Abstract
Refugees have been demonstrated to be at high risk for developing major depressive and posttraumatic stress disorders, but are often not able to benefit from modern advances in psychopharmacology. Besides difficulties in cross-cultural psychiatric diagnosis, problems also arise from cultural differences in the expectation of drug effects and in compliance. Recent evidence has suggested that pharmacokinetic and pharmacodynamic profiles of various psychotropic medications may be different in Asians than in non-Asian patients, leading to differences in dosage requirements and side effect profiles. These issues and their relevance to the care of refugee patients are reviewed.

Abstract
This paper is a brief review which deals with research findings, clinical issues, and strategies in the pharmacotherapy of alcoholism. The pharmacotherapy is presented according to different clinical phases of the alcoholic process. The acute intoxicated patient receives supportive treatment, to be clinically observed to prevent severe respiratory depression, aspiration of vomitus, and severe alcohol withdrawal syndrome. Benzodiazepine therapy is the mainstay in treating alcohol withdrawal syndrome. Disulfiram is the only chemical used in the United States to deter the alcoholic patient from further alcohol drinking. Although there is not a specific agent for alcoholism per se during the sobriety state, the alcoholic patients' concurrent underlying psychiatric conditions (such as schizophrenia, anxiety, and depression) should be treated properly and adequately.

Abstract
The authors review drug biotransformation. Phase I reactions are preconjugation processes that take place through cytochrome P-450--a hepatic mixed function oxidase (MFO) enzyme system with multiple isozymes to metabolize foreign substances. Phase II reactions are conjugation processes of the substrates. Based on the characteristics of the cytochrome P-450 microsomal enzyme systems, the authors explain the clinical phenomena of induction and inhibition of these enzymes when psychotropic agents interact. This article describes both MFO inducers (barbiturates) and inhibitors (cimeditine, fluoxetine and neuroleptic drugs). With this information, clinicians can enhance the ability to monitor drug interactions of psychotropic agents.

Abstract
As of 1989, the psychotropic drugs that have been reported to inhibit female orgasm include antipsychotic agents (thioridazine, trifluoperazine and fluphenazine), the combination drug perphenazine/amitriptyline, antidepressants (phenelzine, isocarboxazid, tranylcypromine, amoxapine, clomipramine, imipramine, nortriptyline and desipramine) and anxiolytic agents (diazepam, flurazepam and alprazolam). The management of psychotropic-drug-induced female anorgasmia includes discontinuation of the offending drug, reduction of the dosage level, a wait for spontaneous remission while the patient remains on the agent and substitution of another medication. The use of bethanechol chloride and cyproheptadine has been successful in resolving anorgasmia while patients continue to receive antidepressants.
