Abstract
BACKGROUND A comprehensive overview of artificial intelligence (AI) for cardiovascular disease (CVD) prediction and a screening tool of AI models (AI-Ms) for independent external validation are lacking. This systematic review aims to identify, describe, and appraise AI-Ms of CVD prediction in the general and special populations and develop a new independent validation score (IVS) for AI-Ms replicability evaluation. METHODS PubMed, Web of Science, Embase, and IEEE library were searched up to July 2021. Data extraction and analysis were performed for the populations, distribution, predictors, algorithms, etc. The risk of bias was evaluated with the prediction risk of bias assessment tool (PROBAST). Subsequently, we designed IVS for model replicability evaluation with five steps in five items, including transparency of algorithms, performance of models, feasibility of reproduction, risk of reproduction, and clinical implication, respectively. The review is registered in PROSPERO (No. CRD42021271789). RESULTS In 20,887 screened references, 79 articles (82.5% in 2017-2021) were included, which contained 114 datasets (67 in Europe and North America, but 0 in Africa). We identified 486 AI-Ms, of which the majority were in development (n = 380), but none of them had undergone independent external validation. A total of 66 idiographic algorithms were found; however, 36.4% were used only once and only 39.4% over three times. A large number of different predictors (range 5-52,000, median 21) and large-span sample size (range 80-3,660,000, median 4466) were observed. All models were at high risk of bias according to PROBAST, primarily due to the incorrect use of statistical methods. IVS analysis confirmed only 10 models as "recommended"; however, 281 and 187 were "not recommended" and "warning," respectively. CONCLUSION AI has led the digital revolution in the field of CVD prediction, but is still in the early stage of development as the defects of research design, report, and evaluation systems. The IVS we developed may contribute to independent external validation and the development of this field.

Abstract
In order to comprehensively evaluate the quality of Viticis Fructus, this study established HPLC fingerprints and evaluated the quality of 24 batches of Viticis Fructus samples from different species by similarity evaluation and multivariate statistical analysis(PCA, HCA, PLS-DA). On this basis, an HPLC method was established to compare the content differences of the main components, including casticin, agnuside, homoorientin, and p-hydroxybenzoic acid. The analysis was performed on the chromatographic column(Waters Symmetry C_(18)) with a gradient mobile phase of acetonitrile(A)-0.05% phosphoric acid solution(B) at the flow rate of 1 mL·min~(-1) and detection wavelength of 258 nm. The column temperature was 30 ℃ and the injection volume was 10 μL. The HPLC fingerprint of 24 batches of Viticis Fructus samples was established with 21 common peaks, and nine peaks were identified. Similarity analysis was carried out based on chromatographic data of 24 batches of chromatographic data of Viticis Fructus, and the results showed that except for DYMJ-16, the similarity of Vitex trifolia var. simplicifolia was ≥0.900, while that of V. trifolia was ≤0.864. In addition, the similarity analysis of two different species showed that the similarity of 16 batches of V. trifolia var. simplicifolia was 0.894-0.997 and that of the eight batches of V. trifolia was between 0.990 and 0.997. The results showed that the similarity of fingerprints of these two species was different, but the similarity between the same species was good. The results of the three multivariate statistical analyses were consistent, which could distinguish the two different species. The VIP analysis results of PLS-DA showed that casticin and agnuside contributed the most to the distinction. The content determination results showed that there was no significant difference in the content of homoorientin and p-hydroxybenzoic acid in Viticis Fructus from different species, but the content of casticin and agnuside was significantly different in different species(P<0.01). The content of casticin was higher in V. trifolia var. simplicifolia, while agnuside was higher in V. trifolia. The findings of this study show that there are differences in fingerprint similarity and component content of Viticis Fructus from different species, which can provide references for the in-depth study of the quality and clinical application of Viticis Fructus.

Abstract
Sarcopenia has attracted increasing attention with the study of nutrition in patients with liver disease. Sarcopenia is an independent risk factor for a poor prognosis of liver disease and is becoming increasingly common in patients with liver disease. Studies have shown that patients with liver disease and sarcopenic obesity have a worse prognosis than patients with liver disease and simple sarcopenia or obesity. In clinical practice, it is easy to recognize patients with malnutrition and decreased muscle mass, but we often ignore those patients with normal body weight or even obesity who will likewise experience muscle mass loss. Simply relying on the monitoring of body mass and body mass index to assess the nutritional and muscle status of patients with liver disease is not accurate. At present, our understanding of the relationship between chronic liver disease and sarcopenic obesity is still poorly understood. In this paper, the research progress on chronic liver disease, sarcopenia, and sarcopenic obesity in recent years is reviewed so as to provide a theoretical basis for improving the clinical prognosis of patients with liver disease.

Abstract
Objective To explore the risk factors of ocular metastasis (OM) in patients with hepatocellular carcinoma (HCC) by analyzing the demographic characteristics and serum markers. Methods From July 2002 to December 2012, 1064 HCC patients were included in our study. The chi-squared test and Student's t-test were used to assess the difference between OM and any other metastasis (NOM). Receiver operating curve (ROC) was used to analyze the diagnostic value of serum biomarkers in HCC patients with OM. Results The incidence of OM in HCC patients was 1.88% in our research. There are no significant differences in age, gender, or histopathology in the OM group and the group without any metastasis. Binary logistic regression analysis presented that compared with the patients without cancer metastasis, carbohydrate antigen 125 (CA-125) and hemoglobin (Hb) were risk factors in hepatocellular carcinoma patients with OM (P < 0.05). The ROC curve analysis showed that the areas under the CA-125, Hb, and CA125+Hb curves were 0.877, 0.554, and 0.431, and the cutoff values of CA-125 and Hb each were 115.78 u/mL and 120.50 g/L. Conclusion Our data suggest that CA-125 and Hb are risk indicators in hepatocellular carcinoma patients with OM, and that CA-125+Hb has potentially greater utility in diagnosing hepatocellular carcinoma.

Abstract
AIM To study the characteristics, relative distribution and to compare causes of red eye in ophthalmic clinics in Urumchi and Shanghai, China. METHODS Data on continuous cases of red-eye patients admitted to the Ophthalmology Center of Xinhua Hospital Affiliated to Shanghai Jiao Tong University and the First Affiliated Hospital of Xinjiang Medical University were collected between November 2018 and September 2019. Demographic data, the incidence of red eye and related disease distribution of all cases were obtained. The independent t-test method was used for age comparison, while the Chi-square test was used to compare classified data information. RESULTS The information on 335 and 415 patients with red eyes in Shanghai and Urumchi were collected, respectively. The main causes of red eye were conjunctival disease and dry eye. The age of female patients with red eyes was significantly higher than that of males, and the proportion of female patients with dry eyes was also higher. Red-eye-related diseases occurred more frequently in patients over 46 years old than in those under 18, and dry eye was more common with increasing age. The incidence of infectious conjunctivitis in Urumchi was significantly higher than that in Shanghai, and allergic conjunctivitis occurred more frequently in spring, summer, or autumn than in winter (all P<0.05). CONCLUSION Significant differences exist in the distribution of red-eye-related diseases in Urumchi and Shanghai regions of China, and distribution varies with age and season, the latter being an important feature of allergic conjunctivitis.

Abstract
So far, intense pulsed light (IPL) has been widely used in the treatment of meibomian gland dysfunction (MGD), but there was still a lack of research on its specific mechanism. Determining whether there was a correlation between liposome changes and remission of clinical signs in patients with MGD treated with IPL was of great significance in the clinical evaluation of efficacy in patients with MGD. Our study enrolled the 10 healthy subjects and 26 adult patients, who were diagnosed with MGD and had not received any alternative treatments for at least 3 months. Each patient received a series of three treatments at 3-week intervals. The meibum was collected before the first treatment (T0) and the third treatment (T2). The significant changes in ocular surface parameters before and after IPL treatment were analyzed. The results showed that IPL significantly improved the symptoms of MGD, including ocular surface disease index (OSDI), tear breakup time (TBUT), redness of conjunctival (CR), corneal fluorescein staining (CF), the meibomian gland expressibility (MGE), and meibum quality (all p < 0.05). Lipidomics analysis of the meibum characterized the changes in lipid profiles induced by IPL. A total of 323 lipid species compounds were identified in the spectrum. A total of 41 lipid species were significantly different in patients with MGD (T0) vs. healthy controls. Following IPL treatment (T2), 24 lipid species were significantly different compared with T0: TG (10 lipid species), LPC (6 lipid species), OAHFA (4 lipid species), Cer (2 lipid species), SM (1 lipid species), and PE (1 lipid specie). Among these lipids, 4 of the lipids was a high correlation with TBUT, 5 was TH, 6 was CR, and 11 was meibum quality. In a ward, IPL treatment can achieve the therapeutic effect by changing the alternations of tear film lipids in patients with MGD. The changes in lipid expression profiles are potential indexes to evaluate the therapeutic effectiveness of IPL treatment or other treatments on MGD.

Abstract
BACKGROUND Diabetes mellitus is a metabolic disorder characterized by prolonged elevation of blood glucose due to various causes. Currently, the relationship between diabetic retinopathy (DR) and altered connectivity of brain function is unclear.
AIM To investigate the relationship between this brain activity and clinical manifestations and behaviors of DR patients by using the amplitude of low-frequency fluctuation (ALFF) technique.
METHODS Twenty-four DR patients and 24 healthy controls (HCs) matched for age and gender were enrolled. We measured and recorded average ALFF values of DR patients and HCs and then classified them using receiver operating characteristic (ROC) curves.
RESULTS ALFF values of both left and right posterior cerebellar lobe and right anterior cingulate gyrus were remarkably higher in the DR patients than in the HCs; however, DR patients had lower values in the bilateral calcarine area. ROC curve analysis of different brain regions demonstrated high accuracy in the area under the curve analysis. There was no significant relationship between mean ALFF values for different regions and clinical presentations in DR patients. Neuronal synchronization abnormalities in some brain regions of DR patients were associated with cognitive and visual disorders.
CONCLUSION Abnormal spontaneous brain activity was observed in many areas of DR patients’ brains, which may suggest a possible link between clinical manifestations and behaviors in DR patients.

Abstract
An UPLC-MS/MS method was developed to simultaneously determine complanatoside A and complanatoside B in rat plasma with rutin as the internal standard and applied to examine the effect of salt-processing on pharmacokinetics of these two flavonoid glycosides. The pharmacokinetic parameters were estimated using DAS 3.2.6 and subjected to independent sample t-test with SPSS 23.0. No significant difference in T_(max) of complanatoside B was observed between the raw and processed groups; however, in the processed group, C_(max) and AUC_(0-12 h) of complanatoside B increased obviously(P<0.05), while MRT_(0-12 h) decreased from(3.34±0.44) h to(1.81±0.36) h(P<0.05). C_(max) [(14.72±11.13) μg·L~(-1)] and MRT_(0-24) [(3.93±0.26) h] of complanatoside A in the raw group were statistically different from those [(35.64±21.99) μg·L~(-1),(1.43±0.24) h] in the processed group(P<0.05). As a result, salt-processing can facilitate the in vivo adsorption and accelerate the excretion of complanatoside A and complanatoside B.

Abstract
Objective: To explore the clinical and pathological features of Dubin-Johnson syndrome. Methods: The clinical and pathological characteristics of 18 cases of Dubin-Johnson syndrome diagnosed in the Department of Pathology of the Third Affiliated Hospital of Sun Yat-sen University from 2008 to 2018 were analyzed. Related literature was reviewed. Results: There were 15 male and three female patients. The male-to-female ratio was 5∶1. The age of the patients ranged from 17 to 73 years (median 24 years). Common clinical manifestations were jaundice, anorexia, and abnormal liver function tests. The pathological feature was the deposition of dark brown particles in the hepatocytes, especially those around the central veins. Conclusions: Dubin-Johnson syndrome mainly occurs in young people. The characteristic pathological changes are the deposition of dark brown particles in the hepatocytes around the central veins of the liver. The diagnosis of Dubin-Johnson syndrome mainly relies on clinical manifestations, laboratory examinations, histopathological examinations and genetic testing. The understanding of Dubin-Johnson syndrome can help reduce the rates of missed diagnosis and misdiagnosis of the disease.

Abstract
Objective Gastric adenocarcinoma originates from the glands in the superficial layer or mucosa of the stomach. It is prone to metastases, of which ocular metastasis (OM) is rare, but once it occurs the disease is considered more serious. The aim of this study was to investigate the risk factors for OM in gastric adenocarcinoma. Methods Patients with gastric adenocarcinoma were recruited to this study between June 2003 and July 2019. Demographic data and serological indicators (SI) were compared between patients with and without OM, and binary logistic regression was used to explore whether the relevant SI may be risk factors for OM of gastric adenocarcinoma. Receiver operating characteristic (ROC) curves were used to analyze different SIs for OM in gastric cancer patients. Results Chi-square tests showed significant between-groups difference in gender composition (P < 0.05), but not in age or histological grade (P > 0.05). t-test results showed that low-density lipoprotein (LDL) and carbohydrate antigen-724 (CA724) were significantly higher in patients with than without OM (P < 0.05). Binary logistic regression analysis showed that LDL was an independent risk factor for OM (P < 0.001). ROC curve analysis showed that the areas under the curves (AUC) for LDL and CA724 were 0.903 and 0.913 respectively, with higher AUC for combined LDL and CA724 (0.934; P < 0.001). Conclusion LDL and CA724 have value as predictors for OM in patients with gastric adenocarcinoma, with higher predictive value when these factors are combined.

Abstract
This research investigates the characteristics of spontaneous brain activity in dysthyroid optic neuropathy patients using the regional homogeneity technique. Sixteen patients with dysthyroid optic neuropathy and 16 thyroid-associated ophthalmopathy patients without dysthyroid optic neuropathy were recruited, matched for weight, height, age, sex, and educational level. All participants underwent resting-state functional nuclear resonance imaging, and the characteristics of spontaneous brain activity were evaluated using the regional homogeneity technique. Each participant in the dysthyroid optic neuropathy group also completed the Hospital Anxiety and Depression scale. Receiver operating characteristic curves were used to compare brain activity between the two groups. Pearson correlation analysis evaluated the relationship between regional homogeneity and clinical manifestations in dysthyroid optic neuropathy patients. In addition, we analyzed the correlation between Hospital Anxiety and Depression scale and regional homogeneity. We found that the regional homogeneity values at the corpus callosum/cingulate gyrus and parietal lobe/middle frontal gyrus significantly decreased in dysthyroid optic neuropathy patients. Regional homogeneity values at the corpus callosum/cingulate gyrus and parietal lobe/middle frontal gyrus were negatively correlated with Hospital Anxiety and Depression scale and disease duration. It was found that the regional homogeneity signal values were significantly lower than in thyroid-associated ophthalmopathy without in dysthyroid optic neuropathy, which may indicate a risk of regional brain dysfunction in dysthyroid optic neuropathy. The results show that regional homogeneity has the potential for early diagnosis and prevent dysthyroid optic neuropathy. In addition, the findings suggest possible mechanisms of dysthyroid optic neuropathy optic nerve injury. They may provide a valuable basis for further research on the pathological mechanisms of dysthyroid optic neuropathy.

Abstract
Background The aim of this study was to explore potential changes in brain function network activity in patients with adult strabismus with amblyopia (SA) using the voxel-wise degree centrality (DC) method. Material/Methods We enrolled 15 patients with SA (6 males, 9 females) and 15 sex-matched healthy controls (HCs). All subjects completed resting functional magnetic resonance imaging scans. Independent-sample t tests and receiver operating characteristic (ROC) curves were used to assess DC value differences between groups, and Pearson correlation analysis was performed to evaluate correlations between DC-changed brain regions and clinical data of patients with SA. Results Compared with the HC group, DC values that were lower in patients with SA included the left middle frontal gyrus and bilateral angular gyri. Increases were observed in the left fusiform gyrus, right lingual gyrus, right middle occipital gyrus, right postcentral gyrus, and left paracentral lobule. However, DC values were not correlated with clinical manifestations. ROC curve analysis showed high accuracy. Conclusions We found abnormal neural activity in specific brain regions in patients with SA. Specifically, we observed significant changes in DC values compared to HCs. These changes may be useful to identify the specific mechanisms involved in brain dysfunction in SA.

Abstract
BACKGROUND Diabetic vitreous hemorrhage (DVH) is a common complication of diabetes. While the diagnostic methods nowadays only concentrate on the eye injury in DVH patients, whether DVH leads to abnormalities of other visual systems, including the eye, the visual cortex, and other brain regions, remains unknown.
AIM To explore the potential changes of brain activity in DVH using regional homogeneity (ReHo) and their relationships with clinical features.
METHODS Thirty-one DVH patients and 31 matched healthy controls (HCs) were recruited. All subjects were examined by resting-state functional magnetic resonance imaging. The neural homogeneity in the brain region was estimated by ReHo method. Pearson correlation analysis was used to evaluate the relationships between average ReHo values and clinical manifestations in DVH patients.
RESULTS Compared with HCs, the ReHo values in the bilateral cerebellar posterior lobes, right superior (RS)/middle occipital gyrus (MOG), and bilateral superior frontal gyrus were significantly increased. In contrast, in the right insula, bilateral medial frontal gyri, and right middle frontal gyrus, the ReHo values were significantly decreased. Furthermore, we found that best-corrected visual acuity of the contralateral eye in patients with DVH presented a positive correlation with the mean ReHo value of the RS/MOG. We also found that depression score of the DVH group presented a negative correlation with the mean ReHo values of the right insula, bilateral medial frontal gyrus, and right middle frontal gyrus.
CONCLUSION We found that DVH may cause dysfunction in multiple brain areas, which may benefit the exploration of pathologic mechanisms in DVH patients.

Abstract
BACKGROUND We used fractional amplitude of low-frequency fluctuation (fALFF) technology to investigate spontaneous cerebral activity in patients with monocular blindness (MB) and in healthy controls (HCs). MATERIAL AND METHODS Thirty MB patient and 15 HCs were included in this study. All subjects were scanned by resting-state functional magnetic resonance imaging (rs-fMRI). The independent sample t test and chi-squared test were applied to analyze demographics of MB patients and HCs. The 2-sample t test and receiver operating characteristic (ROC) curves were applied to identify the difference in average fALFF values between MB patients and HCs. Pearson's correlation analysis was applied to explore the relationship between the average fALFF values of brain areas and clinical behavior in the MB group. RESULTS MB patients had lower fALFF values in the left anterior cingulate and higher fALFF values in the left precuneus and right and left inferior parietal lobes than in HCs. Moreover, the mean fALFF values of MB patients in the left anterior cingulate had negative correlations with the anxiety scale score (r=-0.825, P<0.001) and the depression scale score (r=-0.871, P<0.001). CONCLUSIONS Our study found that MB patients had abnormal spontaneous activities in the visual and vision-related regions. The finding of abnormal neuronal activity helps to reveal the underlying neuropathologic mechanisms of vision loss.

Abstract
BACKGROUND Visual deprivation can lead to abnormal and plastic changes in the brain's visual system and other systems. Although the secondary changes of gray matter in patients have been well studied, the study of white matter is rare. In fact, subtle changes in white matter may be revealed by diffusion tensor imaging, and tract-based spatial statistics can be used to analyze DTI image data. PURPOSE In the present study, diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS) were used to investigate abnormal structural changes in the white matter (WM) of patients with monocular blindness (MB). METHODS We recruited 16 healthy controls (HC) (fourteen males and two females) and 16 patients (fifteen males and one female) with right-eye blindness (without differences in left-eye vision). All patients were of similar age. Data acquisition was performed using magnetic resonance imaging (MRI) and DTI. Voxel-based whole brain comparisons of fractional anisotropy (FA) and radial diffusivity (RD) of WM fibers in patients and HC were performed using the TBSS method. The mean FA and RD values for altered brain regions in MB patients were analyzed via the receiver operating characteristic (ROC) curve. Correlation analysis was performed to investigate the relationships between the average FA (RD) value of the whole brain and anxiety score, depression score, and visual function questionnaire score in MB patients. RESULTS In MB patients, the mean FA of the whole brain was decreased versus HC. Moreover, the FA values of the corpus callosum, the corona radiata, the posterior thalamic radiation, and the right retrolenticular part of internal capsule were significantly decreased. In addition, the average RD value of the whole brain in MB patients was higher than that observed in HC. The mean FA and RD values of brain regions were analyzed using the ROC curve, and the results showed that the area under the ROC curve was more accurate. Furthermore, the average FA and RD values of the whole brain were significantly correlated with anxiety score, depression score, and visual function-related quality of life score. CONCLUSION DTI and TBSS may be useful in examining abnormal spontaneous alterations in the WM of MB patients. The observed changes in FA and RD values may imply the larvaceous neurological mechanism involved in MB.

Abstract
Background To date, there is no validated whole grain assessment tool for children in any Southeast Asian countries. Hence, there is a need for a valid tool to assess whole grain intake among Malaysian children. This study aimed to develop, validate and test the reproducibility of a food frequency questionnaire (FFQ) in estimating whole grain intake among Malaysian children. Methods A total of 392 children participated in the FFQ development and 112 children aged 9–12 years participated in the validation phase; with a subsample of 50 children participating in the reproducibility phase. Three-day diet record (3DR) as the reference method in validation phase. Spearman correlations, mean difference, Bland-Altman plot and cross-classification analyses were used to assess validity. The reproducibility was tested through a repeat administration of the FFQ, with 1 month time interval. Reproducibility analyses involved intra-class correlation coefficient (ICC), Cronbach’s alpha and cross-classification analyses. Results The FFQ consisted of 156 whole grain food items from six food groups. Mean intake of whole grain in FFQ1 and 3DR were correlated well (r = 0.732), demonstrated good acceptance of the FFQ. Bland Altman plots showed relatively good agreement for both the dietary methods. Cross-classification of whole grain intake between the two methods showed that < 9.9% of children were grossly misclassified. Outcomes from ICC (0.989) and Cronbach’s alpha (0.995) demonstrated excellent reliability. All the children were classified in the same or adjacent quartile of whole grain intake. Conclusions Overall, the findings support the validity of the developed FFQ to appropriately estimate the whole grain intake in Malaysian children. This validated FFQ will be a valuable tool for future studies, to analyses the impact of whole grain consumption with disease relationship among Malaysian schoolchildren.

Abstract
The aim of the present study was to assess the local character of spontaneous brain activity in type-2 diabetic patients with vitreous hemorrhage (VH) and its relationship with clinical features via the amplitude of low-frequency fluctuations (ALFF) method. A total of 31 subjects (15 females and 16 males) with type-2 diabetic VH and 31 normal controls (NCs) with similar characteristics (sex, age and educational level) were recruited in the present study. All subjects underwent resting-state functional magnetic resonance imaging scans. The local character of spontaneous brain activity was assessed using the ALFF method. The difference between the type-2 diabetic patients with VH and NCs was determined using receiver operating characteristic curves. Pearson's correlation analysis was applied to evaluate the relationship between the mean ALFF values of specific brain areas and related clinical manifestations in type-2 diabetic patients with VH. The ALFF values of type-2 diabetic patients with VH were significantly increased in the right and left cerebellum posterior lobes, left cerebellum posterior lobe/left lingual gyrus and bilateral superior frontal gyrus/left postcentral gyrus, compared with those obtained for NCs (P<0.05). By contrast, these values were significantly decreased in the left and right middle frontal gyri, right medial frontal gyrus/left anterior cingulate, right inferior frontal gyrus, right superior frontal gyrus, right middle frontal gyrus, right superior frontal gyrus/middle frontal gyrus and left middle frontal gyrus of the former group compared with the NCs (P<0.05). Nevertheless, there was no significant association between the mean ALFF values and clinical characteristics in different brain areas. Unusual spontaneous activity occurred in multiple brain areas, which may suggest the neuropathological mechanisms of visual impairment in type-2 diabetic patients with VH.

Abstract
The difference in pharmacological activities and active components between leaves, barks and flowers of Eucommia ulmoides(EU) are still unclear. However, clarifying the differences in pharmacological effects of different parts of EU is of great significance for the development of EU products, and their corresponding active components provide basis for quality control of different parts of EU. Based on the chemical compositions of different parts of EU, integrated strategy of target prediction and target analysis of the compounds was used to investigate the difference in the pharmacological effects of leaves, barks and followers. The "component-target-function" association network was constructed to mine the specific material basis corresponding to specific efficacy of different parts of EU. In this study, the author found that EU may have the activities of anti-oxidation, neuromodulation, blood pressure regulation, myo-cardial expansion, and anti-apoptosis according to target prediction and function analysis. However, the effects of different parts of EU were different. Leaves were involved in the process of bone development such as osteoblast differentiation and bone mineralization in a specific way. In addition, the leaves may affect the process of bone development by regulating the metabolism of vitamin D and affecting the absorption of calcium. Leaves may also specifically act on estrogen and estradiol response processes where estrogen receptors were involved. Regarding its protective function for the liver, leaves may play a role by regulating vitamin A-related pathways. As compared with leaves, the specific pharmacological effects of barks may be related to the development of the urinary system. Flowers specifically participate in functions related to pain sensation, glutamate signaling pathway, and excitatory postsynaptic potential. Based on the hie-rarchical network of "component-target-pathway", we further found that specific activities of different parts of EU were inseparable from its specific chemical compositions. Phenylpropanoids, terpenoids and rings, iridoids, flavonoids and other components which are specific in leaves can target the specific effects of leaves, while the flavonoids in barks and the quinones in flowers may be the material basis for their respective specific effects. The prediction of the activities of different parts of EU provides a new basis for the focuses and differences in subsequent Eucommia product development. At the same time, the material basis research based on differential efficacy also provides a basis for the quality control of Eucommia differentiated products.

Abstract
To clarify the change and development of original plants of " Manjingzi"( Viticis Fructus),a traditional Chinese medicine,we investigated Vitex species on the ancient Chinese herbal texts. The study concluded that the Vitex trifolia and V. trifolia var.simplicifolia included in the Chinese Pharmacopoeia( 2015 edition) are only two sources of ancient medicinal Viticis Fructus. There are many sources of vines used in ancient times,which are not fixed and unified. The early use of Viticis Fructus is likely to be the V. quinate var. quinata,V. negundo var. cannabifolia and V. negundo var. negundo. From the Tang Dynasty,the use of V. trifolia var. simplicifolia has been appeared. Until Li Shizhen of the Ming Dynasty,the V. trifolia has been used as a source of medicine for the Viticis Fructus,but even so,the source of medicinal plants of Viticis Fructus has not been unified. We suggested V. trifolia var. simplicifolia be used as mainly species for " Manjingzi" due to its widely used in ancient China.

Abstract
PURPOSE To investigate differences in the functional connectivity (FC) of the primary visual cortex between patients with corneal ulcer (CU) and healthy controls (HCs) using resting-state functional magnetic resonance imaging. PATIENTS AND METHODS A total of 30 patients with CU and 30 HCs were closely matched in terms of sex, age, and level of education. Two-sample t-test, receiver operating characteristic curve, and Pearson's correlation coefficient analyses were used to determine the differences in FC between the two groups, the mean FC value of patients with CU and HCs, and the correlation between FC signal values and clinical manifestations in different brain regions of patients. RESULTS The CU group showed significantly elevated FC in the left and right middle frontal gyri and lower FC with the right cuneus compared with the HC group. In addition, the FC of the right cingulate and left superior frontal gyri also increased in the CU group. The receiver operating characteristic curve revealed high diagnostic value in those brain regions. CONCLUSION CU involves aberrant FC of the primary visual cortex in different brain areas, including visual-related and cognitive-related regions. This finding may unveil the underlying neural mechanisms of impaired visual function in CU.

Abstract
PURPOSE In this study, we aimed to investigate the differences in the intrinsic functional connectivity (iFC) of the primary visual cortex (V1), based on resting-state functional magnetic resonance imaging (rs-fMRI), between patients with proliferative diabetic retinopathy (PDR) and healthy controls (HCs). METHODS In total, 26 patients (12 males, 14 females) with PDR and 26 HCs (12 males, 14 females), matched for sex, age, and education status, were enrolled in the study. All individuals underwent rs-fMRI scans. We acquired iFC maps and compared the differences between PDR patients and the HCs. RESULTS The PDR group had significantly increased FC between the left V1 and the right middle frontal gyrus (RMFG), and significantly reduced FC between the left V1 and the cuneus/calcarine/precuneus. In addition, the PDR patients had significantly increased FC between the right V1 and the right superior frontal gyrus (RSFG), and significantly reduced FC between the right V1 and the cuneus/calcarine/precuneus. The individual areas under the curve (AUCs) of FC values for the left V1 were as follows: RMFG (0.871, p < 0.001) and the cuneus/calcarine/precuneus (0.914, p < 0.001), while the AUCs of FC values for the right V1 were as follows: RSFG (0.895, p < 0.001) and the cuneus/calcarine/precuneus (0.918, p < 0.001). CONCLUSIONS The results demonstrated that, in PDR patients, altered iFC in distinct brain regions, including regions related to visual information processing and cognition. Considering the rise in the diabetes mellitus incidence rate and the consequences of PDR, the results could provide promising clues for exploring the neural mechanisms related to PDR and possible approaches for the early identification of PDR.

Abstract
Objective: To analyze the epidemiological characteristics of HIV-infected pregnant women and exposed infant in Guangdong province and identify the factors associated with infant HIV infection through mother-to-child transmission. Methods: National Information System for Prevention of mother-to-child HIV Transmission and Early Infant Diagnosis Information Management Platform were used to collect the individual information about HIV-infected pregnant women and exposed infants who were delivered in Guangdong from January 1, 2014 to December 31 in 2017. The differences in pregnant women's demographic data, history of pregnancy and childbirth, the utilization of mother-to-child transmission prevention services and early infant diagnosis between the infected HIV exposed infants and uninfected HIV exposed infants were compared, and univariate and multivariate logistic regression analyses were conducted to identify the factors associated with mother-to-child HIV transmission. Results: Among 349 HIV infected pregnant women, the proportions of the pregnant women whose HIV infection status were confirmed before pregnancy, during pregnancy and at or after childbirth were 30.4% (106/349), 49.6% (173/349) and 20.0% (70/349) respectively. The proportions of those with sexual partners whose HIV infection status were unknown and those receiving no antiviral treatment were 39.5% (138/349) and 13.2% (46/349) respectively. Among the HIV exposed infants, the mother-to-child transmission rate was 4.2%(15/353), the HIV exposed infants had the first or second early diagnosis tests within 44 (P(25)-P(75): 42-50) days and 96 (P(25)-P(75): 92-106) days after birth, respectively. Univariate logistic regression analysis indicated that the risk for mother-to-child HIV transmission increased in those whose HIV infection status were confirmed at or after childbirth compared with before pregnancy (OR=5.72, 95%CI: 1.52-21.61) and in the group that antiviral treatment was given to either mothers or infants compared with the group that antiviral treatment was given to both mothers and infants (OR=33.56, 95%CI: 9.04-124.55), while there was lower mother-to-child HIV transmission risk in artificial feeding group compared with breast feeding group (OR=0.07, 95%CI: 0.01-0.76). Conclusion: The risk of mother-to-child HIV transmission in Guangdong can be effectively reduced by the measures of early diagnosis, antiviral treatment and artificial feeding as well as the improvement of mother-to-child transmission prevention service.

Abstract
OBJECTIVE To study the changes in gray matter volume (GMV) in patients with advanced monocular blindness (MB) using voxel-based morphometry (VBM). METHODS Thirty-one patients with advanced MB (25 males and six females) and 31 normal controls (25 males and six females) were enrolled. The t test was applied to determine the differences in GMV, white matter volume (WMV), and volume of cerebrospinal fluid in different regions of the brain. The local characteristics of spontaneous concentrations of brain tissue were evaluated by the VBM method. The effects of blindness duration on differences in the GMV were evaluated by correlation and regression analyses. RESULTS Compared with the control group, the GMV was decreased in the upper right margin, bilateral insular cortex, right cingulate gyrus, left occipital gyrus, and right suboccipital lobe, and negatively correlated with blindness duration in the upper right posterior margin, bilateral insular cortex, and right cingulate cortex. CONCLUSIONS We found that patients with MB showed abnormal WMV and GMV, as evidenced by local changes in the brain. In addition, reduced GMV in specific parts of the brain was associated with the duration of blindness, which may indicate neuropathological mechanisms of visual loss in patients with MB.

Abstract
References and our previous experiment showed that the contents of glycosides were significantly decreased,while the contents of aglycones were significantly increased after processing of Cassiae Semen.It may be related to its glycosidases or the heating process. In order to investigate the reasons, high performance liquid chromatographic (HPLC) was used to study the effects of these two factors on contents of Cassiae Semen's main chemical components in processing. The results showed that glycoside hydrolases was present in Cassiae Semen and could rapidly hydrolyze glycosides from Cassiae Semen into aglycones in suitable temperature with sufficient water.However,it didn't show effect on contents change of main constituents in the procedure of Cassiae Semen processing.The reason for content decrease of glycosides and content increase of aglycones in processed Cassiae Semen was glycoside bond cracking to produce corresponding aglycone at high temperature.This study further provides basis for further revealing of the processing mechanism of Cassiae Semen.

Abstract
Introduction Orbital embryonal rhabdomyosarcoma is a rare childhood malignancy with a good prognosis, but the optimal treatment remains unclear. Using a population-based cancer registry, we assessed the prognoses and survival outcomes of patients with orbital embryonal rhabdomyosarcoma according to the local treatment strategy. Patients and methods Patients diagnosed with orbital embryonal rhabdomyosarcoma between 1988 and 2012 as part of the Surveillance Epidemiology and End Results program were included. Univariate and multivariate Cox regression analyses were performed to determine the prognostic factors associated with cause-specific survival (CSS) and overall survival (OS). Results In total, 102 patients were included; their median age was 6 years, 78.4% were white, and 56.9% were male. The median tumor size was 30 mm. Of 20 patients with an available histologic grade, the tumors of 90% were poorly differentiated/undifferentiated. Of 92 patients with available surgical and radiotherapy (RT) statuses, 50 (54.3%), 36 (39.1%), and 6 (6.5%) received surgery and RT, primary RT, and primary surgery, respectively. Ninety-five patients (93.1%) received chemotherapy. The 5- and 10-year CSSs of the entire cohort were 94.3% and 92.2%, respectively. The 5- and 10-year OSs were 93.3% and 91.3%, respectively. In 95 patients who were followed up for at least 12 months, there were no significant prognostic factors related to CSS and OS. Furthermore, the local treatment strategy did not significantly affect CSS (P=0.29) or OS (P=0.468). Conclusion There is no local treatment of choice for orbital embryonal rhabdomyosarcoma in terms of survival. However, RT is a reasonable alternative treatment to surgery.

Abstract
The homology of epidermal growth factor receptor pathway substrate 8 (EPS8), EPS8L3, is elevated significantly in hepatocellular carcinoma (HCC) tissues and cell lines compared with the normal liver tissues and cell lines. The MTT and colony formation assays demonstrated that overexpressing EPS8L3 enhances, while silencing reduces the proliferation of HCC cells. Further experiments illustrated that overexpressing EPS8L3 promotes the expression of p-AKT, Cyclin D1, but inhibits the transcriptional activity of FOXO1. Besides, colony formation assay demonstrated that AKT inhibitor suppresses the effect of EPS8L3 on proliferation in EPS8L3-overexpressing cells, whereas AKT restores the proliferation of EPS8L3-silenced cells, suggesting that EPS8L3 might promote proliferation by hyperactivating the AKT signaling pathway and subsequently inhibiting the FOXO1 transcriptional activity. Our results provide new view between EPS8L3 and progression of human HCC, suggesting that EPS8L3 may be a novel therapeutic target for HCC.

Abstract
To investigate the clinicopathological characteristics and survival of small cell carcinoma of the cervix using Surveillance, Epidemiology, and End Results database. Patients with a diagnosis of small cell carcinoma of the cervix were included between 1988 and 2012. Kaplan-Meier method and Cox regression models were used. A total of 487 patients were included. Of the patients with known International Federation of Gynecology and Obstetrics stage and tumor grade, the stage IV disease was diagnosed in 37.9% patients, and 98.5% patients had poorly or undifferentiated histology. The 5-year cause specific survival and overall survival were 33.0% and 29.4%, respectively. In multivariate analysis, increasing age, advanced stage, and treatment by primary radiotherapy were associated with worse survival outcomes. Small cell carcinoma of the cervix is a rare disease with aggressive characteristics and prone to metastasize and is dismal in prognosis. Reduced survival was associated with increasing age, advanced stage, and treatment by primary radiotherapy.

Abstract
To access possible relationships between breast cancer subtypes (BCS) and patterns of distant metastasis in advanced breast cancer. Breast cancer patients with distant metastasis at two academic centers from 2000-2015 were retrospectively reviewed. The breast cancer was classified into four subtypes: hormone receptor (HR) +/ human epidermal growth factor receptor 2 (HER2) − (i.e., estrogen receptor [ER] + and/or progesterone receptor [PR] +, HER2−); HR+/HER2+ (ER+ and/or PR+, HER2+), HR−/HER2+ (ER− and PR−, and HER2+); and HR−/HER2− (ER− and PR−, and HER2−). A total of 679 patients were identified. The distribution of the BCS was 39.9% (271/679), 23.7% (161/679), 16.8% (114/679), and 19.6% (133/679) in HR+/HER2−, HR+/HER2+, HR−/HER2+, and HR−/HER2−, respectively. Patients with HR+/HER2+ and HR−/HER2+ subtypes were prone to abdominal and pelvic metastasis, those with HR+/HER2− and HR+/HER2+ subtypes were prone to bone metastasis, while patients with the HR−/HER2− subtype were prone to lung/mediastinal and brain metastases. In patients with pleural, axillary and/or neck lymph node, and other distant soft tissue metastases, there was no significant difference in metastatic patterns among the BCS. There are different patterns of distant metastasis associated with different BCS. There should be a different focus in the postoperative follow-up and monitoring of breast cancer patients with different BCS.

Abstract
To investigate the effect of distant metastases sites on survival in patients with de novo stage-IV breast cancer. From 2010 to 2013, patients with a diagnosis of de novo stage-IV breast cancer were identified using the Surveillance, Epidemiology, and End Results database. Univariate and multivariate Cox regression analyses were performed to analyze the effect of distant metastases sites on breast cancer-specific survival and overall survival. A total of 7575 patients were identified. The most common metastatic sites were bone, followed by lung, liver, and brain. Patients with hormone receptor+/human epidermal growth factor receptor 2- and hormone receptor+/human epidermal growth factor receptor 2+ status were more prone to bone metastases. Lung and brain metastases were common in hormone receptor-/human epidermal growth factor receptor 2+ and hormone receptor-/human epidermal growth factor receptor 2- subtypes, and patients with hormone receptor+/ human epidermal growth factor receptor 2+ and hormone receptor-/human epidermal growth factor receptor 2+ subtypes were more prone to liver metastases. Patients with liver and brain metastases had unfavorable prognosis for breast cancer-specific survival and overall survival, whereas bone and lung metastases had no effect on patient survival in multivariate analyses. The hormone receptor-/human epidermal growth factor receptor 2- subtype conferred a significantly poorer outcome in terms of breast cancer-specific survival and overall survival. hormone receptor+/human epidermal growth factor receptor 2+ disease was associated with the best prognosis in terms of breast cancer-specific survival and overall survival. Patients with liver and brain metastases were more likely to experience poor prognosis for breast cancer-specific survival and overall survival by various breast cancer subtypes. Distant metastases sites have differential impact on clinical outcomes in stage-IV breast cancer. Follow-up screening for brain and liver metastases might be effective in improving breast cancer-specific survival and overall survival.

Abstract
The aim of this study was to explore the associations of urinary selenium and polymorphisms in methylation related genes with breast cancer risk and the interactions on the risk. The present study involved in 240 female patients with incident breast cancer and 246 age-matched controls in two affiliated hospitals of Sun Yat-sen University in Guangzhou, China, from October 2009 to July 2010. DNMT1 rs2228611, MTHFR rs1801133, and MTR rs1805087 were genotyped using a matrix-assisted laser desorption/ionization time-of-flight mass spectrometry platform. Urinary concentration of selenium was measured by inductively coupled plasma mass spectrometry. Women with urinary selenium in the second tertile had a significant reduced breast cancer risk compared to those with urinary selenium in the lowest tertile [OR (95%CI): 0.50 (0.30, 0.81)]. DNMT1 rs2228611, MTHFR rs1801133, and MTR rs1805087 were not associated with breast cancer risk. Women with the third tertile of urinary selenium had a significant reduced breast cancer risk compared to those with the lowest tertile among women only with CC genotype [OR (95%CI): 0.55 (0.30, 1.00)] but not CT/TT genotypes [OR (95%CI): 1.58 (0.73, 3.42)] of MTHFR rs1801133 (P for interaction=0.044). Our results suggested that selenium was associated with a decreased risk of breast cancer and this beneficial effect was limited to women with CC genotype of MTHFR rs1801133.

Abstract
Background: Proteins in the lipin family play a key role in lipid synthesis due to their phosphatidate phosphatase activity, and they also act as transcriptional coactivators to regulate the expression of genes involved in lipid metabolism. The lipin family includes three members, lipin1, lipin2, and lipin3, which exhibit tissue-specific expression, indicating that they may have distinct roles in mediating disease. To date, most studies have focused on lipin1, whereas the roles of lipin2 and lipin3 are less understood. Summary: This review introduces the structural characteristics, physiological functions, relationship to lipid metabolism, and patterns of expression of the lipin family proteins, highlighting their roles in lipid metabolic homeostasis. © 2014 S.

Abstract
BACKGROUND Largehead Atractylodes Rhizome (LAR) is the most commonly used Chinese medicine to prevent early pregnancy loss due to threatened miscarriage. However, its safety profile during pregnancy is still not available. Here we aimed to identify the potential adverse effects of LAR on embryo-fetal development as well as prenatal and post-natal growth. METHODS Pregnant mice, rats and rabbits were orally administered with LAR extracts in various doses (from 1×, 2×, 3× and up to 6× clinical doses) at different gestational periods (implantation, gastrulation, organogenesis, maturation and whole gestation). Maternal effects on weight loss, implantation failure and fetal resorption and perinatal effects on developmental delay, growth restriction and congenital malformations were studied. RESULTS In mice, with early LAR exposure, a significant decrease in fetal growth parameters and a significant increase in post-implantation loss were identified. With late LAR exposure, significant increases in gestational duration as well as prenatal and post-natal mortality were found. At high clinical doses, congenital skeletal malformations were recorded. In rabbits, fetal resorption, hydrops fetalis and short ear anomaly were observed. No significant adverse effects were found in rats. CONCLUSIONS Potential reproductive toxicity of LAR in pregnant animals was identified within the clinical dose. Caution should be taken in clinical applications of LAR during pregnancy.

Abstract
A chemical investigation on a South China Sea gorgonian, Menella sp. resulted in the isolation and elucidation of menellin A (1), a highly oxygenated racemate with C(8) skeleton, and a polyhydroxylated steroid, menellsteroid C (2), along with eight known compounds (3-10). The structures of the new compounds were elucidated by means of MS, 1D and 2D NMR spectra, and the relative stereochemistry of 1 was determined by X-ray single-crystal diffraction analysis. In addition, compound 7 was isolated as a new natural product. Compounds 1-3 and 7 were selected to test the anti-inflammatory inhibition against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW264.7 macrophages. 1 and 3 exhibited modest inhibitory effects with IC(50) of 71.3, 33.9 µM, respectively, compared to the positive control aminoguanidine (IC(50) 25.0 µM).

Abstract
OBJECTIVES Our aim was to utilize publicly available and proprietary sources to discover candidate genes important for ocular development. DESIGN AND METHODS The collated information on our 5092 non-redundant clusters was grouped and functional annotation was conducted using gene ontology (FatiGO) for categorizing them with respect to molecular function. The web-based viewer technological platform (H-InvDB) was employed for transcription analyses of in-house high quality fetal eye Expressed Sequence Tags (ESTs). Eye-specific ESTs were also analyzed across species by using EMBEST. RESULTS According to adult eye cDNA libraries, nucleic acid binding and cell structure/cytoskeletal protein genes were the most abundant among the ESTs of fetal eyes. Using cDNA assembly in H-InvDB, 20 (80%) of the 25 most commonly expressed genes in the human eye are also expressed in extraocular tissues. The crystalline gamma S gene is highly expressed in the eye, but not in other tissues. We used EMBEST to compare human fetal eye and octopus eye ESTs and the expression similarity was low (1.6%). This indicated that our fetal eye library contains genes necessary for the developmental process and biological function of the eye, which may not be expressed in the fully developed octopus eyes. The human fetal eye cDNA library also contained highly abundant eye tissue genes, including alphaA-crystallin, eukaryotic translation elongation factor 1 alpha 1 (EEF1A1), bestrophin (VMD2), cystatin C, and transforming growth factor, beta-induced (BIGH3). CONCLUSIONS Our annotated EST set provides a valuable resource for gene discovery and functional genomic analysis. This display will help to appreciate the strengths and weaknesses of the different technological platforms, so that in future studies the maximum amount of beneficial information can be derived from the appropriate use of each method.

Abstract
Somatostatin inhibits gastroenteropancreatic exocrine secretion and is often used after pancreaticoduodenectomy to reduce pancreatic secretion to minimize tissue damage and pancreatic stump complications. Because our earlier clinical work saw a major increase in delayed gastric emptying (DGE) with somatostatin prophylaxis after pylorus-preserving pancreaticoduodenectomy (PPPD), this small-group study was designed to confirm or disprove that observation. From August 1997 to December 2000, a total of 23 post-PPPD patients were randomized to receive somatostatin prophylaxis [somatostain (+)] (n = 11) or not [somatostatin] (-) (n = 12). The incidence of DGE, scintographic solid-phase emptying results on day 14 postoperatively, and sequential fasting plasma motilin levels were compared, as motilin levels are related to both gastric motility and somatostatin levels. The somatostatin(+) group exhibited greatly increased patient complaints of DGE: 9 of 11 (82%) versus 3 of 12 (25%) in the somatostatin(-) group. Radiologic scintography showed somatostatin prophylaxis prolonged the half-time (T(1/2)) of solid-phase emptying: 144.5 +/- 51.4 minutes for somatostatin(+) versus 89.0 +/- 59.9 minutes for somatostatin(-) (p < 0.001). Comparing pre-PPPD and post-PPPD plasma motilin levels prior to somatostatin infusion, motilin decreased 80% in reaction to the surgery. For somatostatin(-) patients, motilin levels oscillated, or "rang," postoperatively, reaching a higher level on day 3, declined to a new record minimum on day 7, and by day 21 were 50% of the original and the slope of the recovery curve was increasing well. In somatostatin(+) patients the same ringing pattern was observed but decreased with motilin levels 30% to 70% lower than in the somatostatin(-) patients. By day 21 somatostatin(+) motilin levels were recovering but still only 20% original levels, and the slope of the recovery curve was not optimistic. On postoperative day 14 the plasma motilin levels (below approximately 6 bg/ml) correlated strongly with DGE for both groups. Despite the small sample size, the results indicated that (1) somatostatin prophylaxis significantly decreases fasting plasma motilin; (2) somatostatin prophylaxis produces lingering suppression of plasma motilin; (3) PPPD surgery itself significantly reduces fasting motilin levels with recovery to 50% normal at day 21; (4) the mechanism of somatostatin-induced DGE seems related to reduced fasting plasma motilin levels.

Abstract
Eukaryotic cells possess several distinct mismatch repair pathways. A mismatch can be introduced in retroviral double-stranded DNA by a pre-existing mutation within the primer binding site (PBS) of the viral RNA genome. In order to evaluate mismatch repair of retroviral double-stranded DNA, Moloney leukemia virus (MLV)-based vectors with a mutation in their PBS were used to infect mismatch repair-competent as well as mismatch repair-deficient cell lines. If the target cells were capable of repairing the mismatch before an infected cell divided, the mismatch within the PBS could be repaired to the wild-type or mutant PBS. If the target cells were unable to repair the mismatch, half the cells in the colony should contain the mutant PBS while the other half should contain the wild-type PBS. To evaluate these predictions, individual colonies were isolated and analyzed by PCR. Almost all mismatch-deficient cell colonies analyzed (cell lines HCT 116 and PMS2-/-) contained both the wild-type and mutated PBS, therefore, mismatches within retroviral double-strand DNA could not be repaired by the mismatch-deficient cells. In contrast, mismatches in approximately 25% of the mismatch repair-competent cell clones analyzed (cell lines HeLa and PMS2+/+) were repaired, while 75% were not. Therefore, the cellular mismatch repair system is able to repair mismatches within viral double-stranded DNA, but at a low frequency.

Abstract
Retroviral RNA molecules are plus, or sense in polarity, equivalent to mRNA. During reverse transcription, the first strand of the DNA molecule synthesized is minus-strand DNA. After the minus strand is polymerized, the plus-strand DNA is synthesized using the minus-strand DNA as the template. In this study, a helper cell line that contains two proviruses with two different mutated gfp genes was constructed. Recombination between the two frameshift mutant genes resulted in a functional gfp. If recombination occurs during minus-strand DNA synthesis, the plus-strand DNA will also contain the functional sequence. After the cell divides, all of its offspring will be green. However, if recombination occurs during plus-strand DNA synthesis, then only the plus-strand DNA will contain the wild-type gfp sequence and the minus-strand DNA will still carry the frameshift mutation. The double-stranded DNA containing this mismatch was subsequently integrated into the host chromosomal DNA of D17 cells, which were unable to repair the majority of mismatches within the retroviral double-strand DNA. After the cell divided, one daughter cell contained the wild-type gfp sequence and the other daughter cell contained the frameshift mutation in the gfp sequence. Under fluorescence microscopy, half the cells in the offspring were green and the other half of the cells were colorless or clear. Thus, we demonstrated that more than 98%, if not all, retroviral recombinations occurred during minus-strand DNA synthesis.

Abstract
This study evaluates the construct validity and internal consistency of a Chronic Illness-Related Stress Inventory (CRSI) for primary care Chinese patients and studies the relationship between chronic illness-related stress and sociodemographic characteristics and indices of disease severity. A total of 301 patients were interviewed using a structured questionnaire. The responses to the CRSI were divided into a frequency scale and a severity scale. Six factors including physical integrity and discomfort, psychosocial function and economic burdens, self-fulfillment and daily life, sexual function, self-esteem, and diet limitations were obtained for each CRSI scale. Except for the last factor, all other factors and the scale as a whole for both scales have a Cronbach alpha of > 0.90. The results of the convergent and discriminant validity analysis were promising. In addition, chronic illness-related stress was related to insurance status and the self-perceived severity of disease.

Abstract
BACKGROUND the hypothesis that disability and death will eventually be compressed to a period late in life needs empirical confirmation. OBJECTIVES we have examined the secular trends of life expectancy and common causes of death in the aged population of Taiwan. METHOD we compared the life expectancy, causes of death and probability of death for people at birth, at age 65 and at age 85 for both sexes from 1974 to 1994 using data from Taiwan government statistics. RESULTS there has been a substantial gain in life expectancy, especially for men age 85 and over, in the past 20 years. . Mortality due to stroke, ischaemic heart disease, hypertension and chronic pulmonary disease has declined. There has been a steep increase in cancer deaths and deaths associated with diabetes mellitus. Tuberculosis and injury-related deaths have declined but pneumonia deaths have increased. For elderly people, the probability of dying from cancer and ischaemic heart disease increased with time. However, the probability of dying from stroke decreased. Although there was a decrease in probability of deaths associated with falls, there was an increase of deaths due to 'frailty' (as judged by falls, pneumonia and septicaemia). CONCLUSIONS cancer is a major cause of death in the elderly population of Taiwan. This rapidly expanding elderly population seemed to suffer from poorer health in the later period of their life.

Abstract
BACKGROUND Patients with chronic medical diseases may have depression that is not recognized by their primary care physicians. OBJECTIVES We aimed to examine the application of Zung's Self-Rating Depression Scale (SDS) in the screening of depression in primary care patients with chronic medical diseases in a Chinese population. METHODS We studied 268 patients with chronic medical diseases in the Family Medicine Outpatient Clinic using a structured questionnaire including basic demographic data, a Chinese version of the SDS and a rating for the self-perceived severity of physical condition. The severity of chronic medical diseases was assessed by the authors using the Duke University Severity of Illness Scale from a chart audit. Fifty patients were randomly selected for a diagnostic interview according to the DSM-IV criteria. The construct validity and internal consistency reliability, sensitivity and specificity of the SDS were examined. RESULTS The results revealed that the SDS has good construct validity and internal consistent reliability in the evaluation of depression in Chinese patients with chronic medical diseases. A cut-off point of 55 had a sensitivity of 66.7% and a specificity of 90.0%. Depressed patients reported more cognitive symptoms than depressed affect and physical symptoms. Female patients had more severe depressed affect than male patients, but males had more prominent diurnal variation of mood than females. CONCLUSIONS We concluded that SDS can be a good screening tool for depression in Chinese patients with chronic medical diseases. Owing to constraints in the expression of sexual desire in the Chinese, elderly subjects tended to report loss of libido in the response to the SDS.
