Abstract
Aim: This study was designed to systematically evaluate the effects of growth factor (GF) for therapeutic angiogenesis on ischemic heart disease (IHD) by pooling the results of randomized controlled trials (RCTs). Methods and Results: PubMed, EMBASE, and CENTRAL databases were searched from inception to October 2022. RCTs, investigating the effects of GF therapy on IHD, were included. The risk bias of included study was assessed according to Cochrane tool. Weighted mean difference (WMD), calculated with fixed effect model or random effect model, was used to evaluate the effects of GF therapy on left ventricular ejection fraction (LVEF) and Canadian Cardiovascular Society (CCS) angina class. Relative risk (RR) was used to evaluate the effects of GF therapy on all-cause mortality, major adverse cardiovascular events (MACE) and revascularization. Meta-analysis, meta-regression analysis and publication bias analysis were performed by RevMan 5.3 or Stata 15.1 software. Twenty-nine studies involving 2899 IHD patients (1,577 patients in GF group and 1,322 patients in control group) were included. Compared with the control group, GF therapy did not reduce all-cause mortality (RR: 0.82; 95% CI: 0.54-1.24; p = 0.341), MACE [(RR: 0.83; 95% CI: 0.61-1.12; p = 0.227), revascularization (RR: 1.27, 95% CI: 0.82-1.96, p = 0.290) and CCS angina class (WMD: -0.08, 95% CI: -0.36 to 0.20, p = 0.560). However, GF therapy could increase LVEF during short-term follow-up (<1 year). Conclusion: GF for therapeutic angiogenesis was beneficial for increasing LVEF during short-term follow-up (<1 year), however, the therapy was not efficacious in decreasing all-cause mortality, MACE and revascularization.

Abstract
To analyze the clinical characteristics of patients with antisynthetase syndrome (ASS) and positive anti-Ro52 antibody. The clinical data of 203 ASS patients admitted to the First Affiliated Hospital of Zhengzhou University from 2017 to 2020 were analyzed retrospectively. Demographics, clinical manifestations, laboratory results, treatment and outcome were collected including data of 18 patients with rapidly progressive interstitial lung disease (RP-ILD). In total, the majority were women (148,72.9%). The average onset age was (51.9±13.3) years. There were 163 (80.3%) patients with positive anti-Ro52 antibody. The positivity in women (77.3% vs. 55.0%, P=0.004) was higher, and the median time from disease onset to diagnosis [4.5 (2.0, 24.0) months vs. 2.0 (1.0, 12.0) months, P=0.024] was longer in patients with positive anti-Ro52 antibody than those negative. Compared with negative patients, patients with positive anti-Ro52 antibody had a higher incidence of interstitial lung disease (ILD) (96.9% vs. 65.0%, P<0.001), arthritis (33.7% vs. 17.5%, P=0.046), and arthralgia (39.3% vs. 20.0%, P=0.022). Higher rate of positve antinuclear antibody (ANA) (85.3% vs. 55.0%, P<0.001), lower rate of positive anti-Jo-1 antibody (32.5% vs. 50.0%, P=0.039), lower albumin level [(34.6±5.2) g/L vs. (37.3±4.7) g/L,P=0.004] and lower lymphocyte counts [(1.4±0.8) ×109/L vs. (1.8±0.8) ×109/L, P=0.014] were more common in patients with positive anti-Ro52 antibody. The presence of anti-Ro52 antibody is associated with a particular phenotype of ASS, leading to common ILD, involvement of joints, high ANA positivity, low albumin and low lymphocyte counts.

Abstract
Objective: To analyze the association between high density lipoprotein cholesterol (HDL-C) and the risk of cardiovascular disease mortality. Methods: A total of 71 618 residents aged over 18 years with complete baseline data, who were filed on the health information big data platform of Yinzhou district, Ningbo city, Zhejiang Province from 2009 to 2014, were selected as the research population. The research population were divided into four groups according to the level of HDL-C: low-level group (HDL-C<1.0 mmol/L), intermediate-level group (1.0 mmol/L≤HDL-C<1.5 mmol/L), medium-high-level group (1.5 mmol/L≤HDL-C<2.0 mmol/L) and high-level group (HDL-C≥2.0 mmol/L). Cox proportional hazard model was used to calculate the risk ratio of cardiovascular diseases mortality in different groups. Results: The study population was followed up for a total of 427 989.4 person-years, follow-up time of (5.98±1.04)years. During the follow-up period, there were 799 deaths due to cardiovascular diseases. After adjusting for confounding factors, compared with the medium-high-level group as the reference group, the HR (95%CI) for cardiovascular diseases mortality was 1.43 (1.13-1.82) in the low-level group and 1.22 (1.02-1.46) in the high-level group. Conclusion: The low level of HDL-C (<1.5 mmol/L) is associated with a higher risk of cardiovascular disease deaths. The level of HDL-C can be used as a biological indicator to monitor the development of cardiovascular diseases and guide treatment.

Abstract
BACKGROUND AND AIMS Although low-density lipoprotein cholesterol (LDL-C) has been considered as a risk factor of atherosclerotic cardiovascular disease, limited studies can be available to evaluate the association of LDL-C with risk of mortality in the general population. This study aimed to examine the association of LDL-C level with risk of mortality using a propensity-score weighting method in a Chinese population, based on the health examination data. METHODS We performed a retrospective cohort study with 65,517 participants aged 40 years or older in Ningbo city, Zhejiang. LDL-C levels were categorized as five groups according to the Chinese dyslipidemia guidelines in adults. To minimize potential biases resulting from a complex array of covariates, we implemented a generalized boosted model to generate propensity-score weights on covariates. Then, we used Cox proportional hazard regression models with all-cause and cause-specific mortality as the dependent variables to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs). RESULTS During the 439,186.5 person years of follow-up, 2403 deaths occurred. Compared with the median LDL-C group (100-130 mg/dL), subjects with extremely low LDL-C levels (group 1) had a higher risk of deaths from all-cause (HR = 2.53, 95% CI:1.80-3.53), CVD (HR = 1.84, 95% CI: 1.28-2.61), ischemic stroke (HR = 2.29, 95% CI:1.32-3.94), hemorrhagic stroke (HR = 3.49, 95% CI: 1.57-7.85), and cancer (HR = 2.12, 95% CI: 1.04-4.31) while the corresponding HRs in LDL-C group 2 were relatively lower than that in group 1. CONCLUSIONS Low LDL-C levels were associated with an increased risk of all-cause, CVD, ischemic stroke, hemorrhagic stroke, and cancer mortality in the Chinese population.

Abstract
BACKGROUND AND AIMS High-density lipoprotein cholesterol (HDL-C) concentration and variability are both important factors of cardiovascular disease (CVD) and mortality. We aimed to explore the associations of HDL-C and longitudinal change in HDL-C with risk of mortality. METHODS AND RESULTS We recruited a total of 69,163 participants aged ≥40 years and had medical examination records of HDL-C during 2010-2014 from the Yinzhou District, Ningbo, China. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards regression models. We observed a non-linear association of HDL-C with risks of non-accidental and CVD mortality. Compared with the moderate concentration group (1.4-1.6 mmol/L), HDL-C <1 mmol/L was associated with a higher risk of non-accidental mortality (HR: 1.13 (95% CI: 1.01-1.27)) and both HDL-C <1 mmol/L and ≥2 mmol/L were associated with a higher risk of CVD mortality (HRs: 1.23 (95% CI: 1.01-1.50) and 1.37 (95% CI: 1.03-1.82), respectively). Compared with the stable group ([-0.1, +0.1 mmol/L]), a large decrease ([-0.5, -0.3 mmol/L]) and very large decrease (<-0.5 mmol/L) in HDL-C were associated with a higher risk of non-accidental mortality (HRs: 1.40 (95% CI: 1.21-1.63) and 1.78 (95% CI: 1.44-2.20), respectively). Similar results were observed for CVD mortality and cancer mortality. CONCLUSION Extremely low or high HDL-C and a large decrease or very large decrease in HDL-C were associated with a higher risk of cause-specific mortality. Monitoring of HDL-C may have utility in identifying individuals at higher risk of mortality.

Abstract
Objective Unprecedented rigorous public health measures were implemented during the coronavirus disease 2019 (COVID-19) epidemic, but it is still unclear how the intervention influenced hospital visits for different types of diseases. We aimed to evaluate the impact of the intervention on hospital visits in Yinzhou District, Ningbo, Zhejiang province, China. Methods We conducted an interrupted time-series analysis from 1 January 2017 to 6 September 2020 based on the Yinzhou Health Information System in Ningbo, Zhejiang province. The beginning of the intervention was on 23 January 2020, and thus, there were 160 weeks before the intervention and 32 weeks after the implementation of the intervention. Level changes between expected and observed hospital visits in the post-intervention period were estimated using quasi-Poisson regression models. Results Compared with the expected level, there was an estimated decrease of −22.60% (95% confidence interval (CI): −27.53%, −17.36%) in the observed total hospital visits following the intervention. Observed hospital visits for diseases of the respiratory system were found to be decreased dramatically (−62.25%; 95% CI: −65.62%, −58.60%). However, observed hospital visits for certain diseases were estimated to be increased, including diseases of the nervous system (+11.17%; 95% CI: +3.21%, +19.74%); diseases of pregnancy, childbirth and the puerperium (+27.01%; 95% CI: +17.89%, +36.85%); certain conditions originating in the perinatal period (+45.05%; 95% CI: +30.24%, +61.56%); and congenital malformation deformations and chromosomal abnormalities (+35.50%; 95% CI: +21.24%, +51.45%). Conclusions Our findings provided scientific evidence that cause-specific hospital visits evolve differently following the intervention during the COVID-19 epidemic.

Abstract
Objective: To investigate the intrinsic organization of cortical circuitry in individuals with subjective cognitive decline (SCD) via resting-state functional magnetic resonance imaging (rs-fMRI) connectome analysis and its correlation with cognitive level. Methods: From June 2017 to November 2019, thirty-six middle-aged and elderly individuals with complaints of memory decline and 32 normal controls (NC) were enrolled from communities in Nanjing. We collected cognitive scale performance,T1-weighted imaging (T1WI) and rs-fMRI data of all subjects. There were 5 males and 31 females in the SCD group, with an average age of (64±5) years. In the NC group, there were 8 males and 24 females, with an average age of (65±5) years. Preprocessing of rs-fMRI data was conducted, then the cerebral cortex was divided into 333 cortical parcels (nodes) and 10 predefined communities according to the prior template. Further, we established full connection matrices between cortical parcels and calculated the within-module degree (WMD) and participation coefficient (PC) of each node based on the matrices. The WMD and PC values were compared between the SCD and NC groups,and their correlations with cognitive scale performance were analyzed. Results: Compared to the NC group,the SCD group showed increased WMD in the dorsolateral prefrontal cortex (DLPFC)(P<0.05,FDR corrected) and the middle frontal gyrus (P<0.005,uncorrected) of the right frontoparietal network (FPN). The SCD group also showed decreased WMD(P<0.05,FDR corrected) in the superior occipital gyrus of the left visual network (VN) and decreased PC (P<0.005,uncorrected) in the supramarginal gyrus of the left dorsal attention network (DAN). The WMD values in the DLPFC showed significant positive correlations with the auditory verbal learning test (AVLT)short-delayed memory (r=0.364,P=0.029),recognition memory (r=0.364, P=0.029) and the Boston naming test scores (BNT, r=0.356, P=0.033)in the SCD group. The PC values in the supramarginal gyrus were significantly positively correlated with the BNT scores (r=0.413, P=0.012) in the SCD group. Conclusion: Cortical network imbalance and reconstruction characterized by decreased intra-module connectivity of VN and inter-module connectivity of DAN exist in SCD subjects,while increased intra-module connectivity of FPN may serve in a compensatory way for the early cognitive decline.

Abstract
Objective: To compare the efficacy and safety of Changsulin® with Lantus® in treating patients with type 2 diabetes mellitus (T2DM). Methods: This was a phase Ⅲ, multicenter, randomized, open-label, parallel-group, active-controlled clinical trial. A total of 578 participants with T2DM inadequately controlled on oral hypoglycemic agents were randomized 3∶1 to Changsulin® or Lantus® treatment for 24 weeks. The efficacy measures included changes in glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2h postprandial plasma glucose (2hPG), 8-point self-monitoring of blood glucose (SMBG) profiles from baseline, and proportions of subjects achieving targets of HbA1c and FPG. The safety outcomes included rates of hypoglycemia, adverse events (AEs) and anti-insulin glargine antibody. Results: After 24 weeks of treatment, mean HbAlc decreased 1.16% and 1.25%, FPG decreased 3.05 mmol/L and 2.90 mmol/L, 2hPG decreased 2.49 mmol/L and 2.38 mmol/L in Changsulin® and in Lantus®, respectively. No significant differences could be viewed in above parameters between the two groups (all P>0.05). There were also no significant differences between Changsulin® and Lantus® in 8-point SMBG profiles from baseline and proportions of subjects achieving the targets of HbA1c and FPG (all P>0.05). The rates of total hypoglycemia (38.00% and 39.01% for Changsulin® and Lantus®, respectively) and nocturnal hypoglycemia (17.25% and 16.31% for Changsulin® and Lantus®, respectively) were similar between the two groups (all P>0.05). Most of the hypoglycemia events were asymptomatic, and no severe hypoglycemia were found in both groups. No differences were observed in rates of AEs (61.77% vs.52.48%) and anti-insulin glargine antibody (after 24 weeks of treatment, 6.91% vs.3.65%) between the two groups (all P>0.05). Conclusions: Changsulin® shows similar efficacy and safety profiles compared with Lantus® and Changsulin® treatment was well tolerated in patients with T2DM.

Abstract
INTRODUCTION Although numerous studies have suggested that lifestyle-related factors are associated with chronic diseases and preventable deaths, limited evidence is available for the Chinese population. METHODS This study established a prospective cohort of >360,000 residents on the basis of the Yinzhou Health Information System in China during 2004-2017 and calculated the combined effects of lifestyle-related factors, including BMI, smoking, alcohol consumption, and physical activity, using a points system. A Cox regression model estimated the combined effects of lifestyle-related factors on total mortality, and a competing risk model estimated the combined effects on cancer and cardiovascular disease mortality. All data analyses were conducted in 2018‒2019. RESULTS During 3,755,879 person-years of follow-up, 11,791 deaths were identified, including 4,983 from cancer and 3,143 from cardiovascular disease. Having a standard BMI, never smoking, never drinking, and engaging in physical activity more than 4 times per week had protective effects on total mortality. Overall, the risk of total and cause-specific mortality increased with the increment of risk score. Compared with subjects in the lowest quartile, the risk of total and cause-specific mortality peaked among individuals in the fourth quartile (total mortality: hazard ratio=1.87, 95% CI=1.77, 1.98; cancer mortality: hazard ratio=2.05, 95% CI=1.87, 2.25; cardiovascular disease mortality: hazard ratio=1.51, 95% CI=1.35, 1.68). Sensitivity analyses excluding individuals with follow-up <3 years did not materially change the results. CONCLUSIONS The combined effects of lifestyle-related factors, including BMI, smoking, alcohol drinking, and physical activity, are associated with total, cancer, and cardiovascular disease mortality among the Chinese population.

Abstract
Ambient particulate matter is one of the main risk factors of chronic obstructive pulmonary disease (COPD) in developing countries. However, the studies were scant in China concerning the health effects of the fine particulate matter (PM2.5; particulate matter ≤ 2.5 μm in diameter) on hospital visits for COPD. We applied a generalized additive model (GAM) to calculate relative risks (RRs) with 95% confidence intervals (CIs) for the associations between hospital visits for COPD and an interquartile range (24.50 μg/m3) increment of ambient PM2.5 concentrations in Yinzhou District between 2016 and 2018. The ambient PM2.5 concentration was positively associated with hospital visits for COPD at a distributed lag of 0-7 days (RR = 1.073, 95% CI, 1.016, 1.133). In the stratified analysis, we found that the association between ambient PM2.5 and COPD was stronger during the warm season (April to September) than that during the cold season (October to March), but we did not observe statistically significant differences in age groups (< 60 years and ≥ 60 years) or gender groups (male and female) related to the effects of PM2.5. The associations between ambient PM2.5 and COPD became partially attenuated after the adjustment for gaseous pollutants in subgroups. Our findings could provide evidence that regulations for controlling both PM2.5 and gaseous pollutants should be implemented to protect the overall population.

Abstract
Superconductivity in monolayer transition metal dichalcogenides is characterized by Ising-type pairing induced via a strong Zeeman-type spin-orbit coupling. When two transition metal dichalcogenides layers are coupled, more exotic superconducting phases emerge, which depend on the ratio of Ising-type protection and interlayer coupling strength. Here, we induce superconductivity in suspended MoS2 bilayers and unveil a coupled superconducting state with strong Ising-type spin-orbit coupling. Gating the bilayer symmetrically from both sides by ionic liquid gating varies the interlayer interaction and accesses electronic states with broken local inversion symmetry while maintaining the global inversion symmetry. We observe a strong suppression of the Ising protection that evidences a coupled superconducting state. The symmetric gating scheme not only induces superconductivity in both atomic sheets but also controls the Josephson coupling between the layers, which gives rise to a dimensional crossover in the bilayer.

Abstract
BACKGROUND AND AIMS The relationship between serum total cholesterol (TC) and mortality remains inconsistent. Additionally, intra-individual variability of cholesterol has been of increasing interest as a new indicator for health outcomes. We aimed to examine the association between TC and its variability and risk of mortality. METHODS AND RESULTS We performed a retrospective cohort study with 122,645 individuals aged over 40 years in Ningbo, China. The intra-individual variability was calculated using four metrics including standard deviation, coefficient variation, variation independent of mean and average successive variability. Hazard ratios and 95% confidence intervals were estimated for the associations of baseline and variability in TC with risk of mortality by Cox proportional hazards regression models. During 591,585.3 person-years of follow-up, 4563 deaths (including 1365 from cardiovascular disease, 788 from stroke and 1514 from cancer) occurred. A U-shaped association was observed for baseline TC level and risk of total, cardiovascular and cancer mortality, with lowest mortality at 5.46 mmol/L, 5.04 mmol/L and 5.51 mmol/L, respectively. As compared with subjects with TC variability in the lowest quartile, individuals in the highest quartile had 21% higher risk of all-cause mortality (HR = 1.21, 95% CI: 1.05 to 1.40), and 41% higher risk of CVD mortality (HR = 1.41, 95%CI: 1.10 to 1.81). CONCLUSION Both too low and too high baseline TC level were associated with higher risk of total, cardiovascular disease and cancer mortality. Variability of TC could be a risk factor of total and CVD mortality, independent of mean TC level. Future studies are needed to confirm these findings.

Abstract
Objective: To investigate the effect of G protein-coupled estrogen receptor (GPER) on proliferation and autophagy in prostatic epithelial cells. Methods: Cell Counting Kit-8 (CCK8) assay was used to observe the growth of BPH-1 and RWPE-1 cells after treating with or not with estradiol or GPER selective agonist G1. Autophagy was quantified with Western blot and Cyto-ID autophagy detection kit after treating with estradiol, G1 or both G1 and G15 in the same cells. Results: The OD value in estrogen group and G1 group was significantly lower than those in control group (P<0.01). Compared with control group, Western blot and Cyto-ID green reagent staining revealed that the ratio of LC3Ⅱ/LC3Ⅰ and the relative fluorescence intensity of BPH-1 and RWPE-1 cells were decreased in G1 group and estradiol group (P<0.01). Pretreatment with G15 reversed the effect of G1 (P<0.05). Conclusion: The activation of GPER leads to the inhibition of autophagy and cell proliferation.

Abstract
Objective: To analyze clinical features, prognosis and treatment of lymphocytic hypophysitis (LYH). Methods: The clinical data, treatments and outcomes of 18 cases diagnosed as LYH at Chinese PLA General Hospital between January 2001 and July 2017 was respectively reviewed. Results: Eighteen patients with histology-proven LYH (13 females and 5 males ) were identified. All lymphocytic adenohypophysitis (LAH) were females(n=6), two of whom were associated with pregnancy. Eleven patients (6 females and 5 males) had lymphocytic panhypophysitis (LPH) and one(female) had hypothalamitis. Pre-treatment evaluation revealed that 11 patients presented with symptoms of intracranial space-occupying lesions, 12 patients had symptoms of anterior pituitary hormone deficiencies, and 12 patients had central diabetes insipidus (CDI). All patients had space-occupying lesions on magnetic resonance imaging (MRI), which were symmetrically enlarged and homogenously enhanced with or without pituitary stalk thickening. Before or after surgery, 11 patients received immunosuppressant therapy or radiotherapy to alleviate space-occupying effect. After 4-204 months follow-up, 5 patients had a relapse and received immunosuppressants, radiotherapy or surgery to achieve remission. Full recovery (both symptomatic and radiographic) was seen in 6 patients, and 11 patients maintained stable replacement therapy. Conclusions: LYH presents with acute space-occupying effects such as headache, visual disturbances, hypopituitarism, CDI and mild hyperprolactinemia, especially with characteristic radiographic manifestations. Usually, surgery reliably establishes diagnosis, and immunosuppressant therapy is a necessity. On the whole, LYH has a good prognosis.

Abstract
Objective: To summarize and analyze the clinical features and etiologies in hospitalized patients with syndrome of inappropriate antidiuretics (SIAD) during the past 25 years. Methods: All data of 128 patients with SIAD admitted to Chinese PLA General Hospital since January 1991 to January 2016 were collected. SIAD was diagnosed based on the 1957 criterion. Results: (1) The most frequent causes of increased inappropriate secretion of vasopressin were malignant tumors, lung diseases (e. g. pneumonia), and central nervous system diseases, in which malignant tumors accounted for 38.28% of the SIAD. (2) During the past 25 years, the proportion of malignant diseases declined from 4/7 to 35.29%, while, the proportion of pulmonary infection increased from 1/7 to 35.29% (P<0.05). (3) The patients with malignant tumors had the lowest serum sodium and serum osmolality among all SIAD patients. (4) CT scan had a high diagnostic value for chest and brain detection. (5) Among three SIAD subjects with unknown reasons at onset, two were diagnosed with small cell lung cancer and one with gastric cancer during follow-up. Conclusion: The etiology of SIAD is complex and it could be attributed to multifarious etiological factors. Malignant tumors account for the largest proportion of all patients, and pulmonary infection was ranked in second place. Cautions on tumors have to be taken when serum sodium of a SIAD patient is below 118.1 mmol/L.

Abstract
Objective: To determine the effect of the surgical and conservative approaches on the metabolic profiles in patients with subclinical Cushing's syndrome (SCS) in adrenal incidentalomas (AI). Methods: A hundred and thirty AI patients with SCS in Department of Endocrinology, PLA General Hospital between January 2008 and December 2016 were studied, surgery was performed in 88 patients (surgical group), and the rest received conservative approach (conservative group). The improvement/worsening of blood pressure, blood glucose, lipid profiles and body weight after a duration of >18 months follow-up were analyzed, respectively. Results: Baseline demographics, clinical characteristics were similar between surgical and conservative groups. In the surgical group, blood pressure, blood glucose, lipid profiles and body weight improved more frequently than that in conservative group (29.69% vs 3.12%, P=0.003; 10.94% vs 3.12%, P=0.262; 7.81% vs 3.12%, P=0.660; 39.06% vs 9.38%, P=0.004, respectively). In conservative group, blood pressure, blood glucose, lipid profiles and body weight worsened more frequently than that in surgical group (28.13% vs 0, P<0.001; 25.0% vs 0, P<0.001; 18.75% vs 0, P=0.003; 40.62% vs 20.31%, P=0.051, respectively). Logistic regression analysis indicated surgical treatment was associated with improvement of blood pressure (OR=10.687, 95%CI: 1.279-89.299) and weight loss (OR=5.541, 95%CI: 1.404-21.872) independently of gender, age, duration of follow-up, serum cortisol level after 1 mg-dexamethasone suppression test and the mass size. Conclusion: In AI patients with SCS, surgery was beneficial in the aspect of metabolic profiles.

Abstract
By dual gating a few-layer MoS_{2} flake, we induce spatially separated electronic states showing superconductivity and Shubnikov-de Haas (SdH) oscillations. While the highly confined superconductivity forms at the K/K^{'} valleys of the topmost layer, the SdH oscillations are contributed by the electrons residing in the Q/Q^{'} valleys of the rest of the bottom layers, which is confirmed by the extracted Landau level degeneracy of 3, electron effective mass of 0.6m_{e}, and carrier density of 5×10^{12} cm^{-2}. Mimicking conventional heterostructures, the interaction between the heteroelectronic states can be electrically manipulated, which enables "bipolarlike" superconducting transistor operation. The off-on-off switching pattern can be continuously accessed at low temperatures by a field effect depletion of carriers with a negative back gate bias and the proximity effect between the top superconducting layer and the bottom metallic layers that quenches the superconductivity at a positive back gate bias.

Abstract
To improve the differential diagnosis of sellar region mass, 4 cases with sellar mass and misdiagnosed as lymphocytic hypophysitis (LYH) were reviewed retrospectively.The 4 patients (2 male and 2 female) aged 20-60 years old were all presented with symptoms of headache, polydipsia and polyuria.Biochemical studies confirmed the diagnoses of central diabetes insipidus and hypopituitarism.Head MRI scans showed LYH like image for all the cases, and, thus, high dose methylprednisolone pulse therapy (HDMPT) was applied to the patients.Their symptoms deteriorated and the sellar mass enlarged after a short period of partial improvement.Operations were performed in all the patients.Histology study showed craniopharyngioma with abscess, primary abscess, secondary hypophysitis caused by Wegener's granulomatosis, and germinoma with secondary hypophysitis, respectively.In conclusion, surgery or biopsy is necessary for those who presented with sellar region mass and was suspected to be with LYH, but with poor response or even worse after HDMPT.

Abstract
Objective: To analyze age-related change in cerebral matter tract, especially fractional anisotropy, based on automating fiber-tract quantification(AFQ). Methods: A total of 64 years old normal persons and 43 young volunteers were enrolled respectively from the Affiliated Drum Tower Hospital of Nanjing University Medical School and community from January 2015 to June 2016.All of them underwent MRI scan, which included DTI and 3D T(1)WI sequence .All cases were divided into 3 groups according to their ages, the young group 20-35 years old, the middle old group 60-75 years old, the old group 76-90 years old.AFQ was used to identify 20 major white matter tracts in brains of all subjects and make measurements at anatomically equivalent locations along their trajectories. Results: The FA change trend of each fiber was similar among three groups. The old and the middle old group had different FA value in both sides of inferior fronto-occipital fasciculus(left t=-2.73, right t=-6.12, P<0.05), thalamic radiation(left t=-4.79, right t=-19.61, P<0.05), arcuate(left t=10.53, right t=-2.72, P<0.05), callosum forceps(genu t=-2.66, splenium t=28.64, P<0.05), cingulum(left t=-4.53, right t=-2.22, P<0.05)and right corticospinal tract(t=3.10, P<0.05), among which each location of callosum forceps minor was different between the old group and the young group, and this area decreased in the middle group. The old group had different FA value in both sides of uncinate fasciculus(left t=-4.52, right t=-4.53, P<0.05), left corticospinal tract(t=-2.19, P<0.05)and right inferior longitudinal fasciculus(t=11.12, P<0.05). Compared to the young group, there was no statistical difference in the FA of both superior longitudinal fasciculus and left inferior longitudinal fasciculus in the old and the middle old group. Conclusion: AFQ has an impact on the further specific study of the age-related white matter tract.

Abstract
Objective: To analyze the correlation between white matter integrity and spatial navigation impairment in patients with mild cognitive impairment (MCI). Methods: A total of 27 MCI subjects and 24 healthy controls were enrolled from the Affiliated Drum Tower Hospital of Nanjing University Medical School from May 2015 to February 2016, who underwent 3.0 T MRI scan and 2D-computer version spatial navigation test.DTI preprocessing and tract-based spatial statistics (TBSS) were performed by PANDA.Two sample t-test and partial correlation coefficients were performed to investigate the correlation of white matter impairments and spatial navigation decline. Results: Relative to controls, MCI showed worse egocentric navigation (t=-2.202, P<0.05). Decreased FA in superior longitudinal fasciculus (left t=2.95, right t=2.95, P<0.05), inferior longitudinal fasciculus and inferior fronto-occipital fasciculus (left t=2.66, right t=2.96, P<0.05), corpus callosum (t=2.09, P<0.05), cingulum (left t=2.76, right t=2.41, P<0.05), fornix (t=4.83, P<0.05), and corticospinal tract (left t=2.33, right t=2.26, P<0.05), were found in the MCI subjects.The decreased FA value of superior longitudinal fasciculus (left r=-0.354, right r=-0.347, P<0.05), inferior longitudinal fasciculus (left r=-0.338, right r=-0.336, P<0.05), cingulum (left r=-0.395, right r=-0.370, P<0.05), right corticospinal tract (r=-0.362, P<0.05) and fornix (r=-0.369, P<0.05) were correlated with increased ego average total error.Allo average total error were negative correlated with FA value of superior longitudinal fasciculus (left r=-0.329, right r=-0.350, P<0.05), inferior longitudinal fasciculus (left r=-0.349, right r=-0.378, P<0.05), splenium of corpus callosum (r=-0.364, P<0.05) and cingulum (left r=-0.340, right r=-0.406, P<0.05). Conclusion: This study implicated the potential white matter structural basis of spatial navigation impairment and will have an impact on the further study of the neurobiological mechanisms of human spatial navigation ability.

Abstract
Objective: To analyze the clinical features and outcomes of congenital adrenal hyperplasia (CAH) with adenomatoid adrenal gland. Methods: Nineteen patients clinically confirmed as CAH with adenomatoid adrenal gland, from 2008 to 2015 in Deparment of Endocrinology of Chinese PLA General Hospital, were retrospectively analyzed, and the outcomes of the treatment were followed up. Results: Seventy-six patients were clinically confirmed as CAH, from 2008 to 2015 in PLA hospital. Nineteen of them have accompanied with adenomatoid adrenal gland. Of the 19 confirmed cases, 7 were male, and 12 were female. The mean age was (33.3±14.8) years old. Nineteen confirmed cases were consisted of 10 cases of 21-hydroxylase deficiency (OHD), 6 cases of 17α-OHD, and 3 cases of 11β-OHD. Of the 19 cases, 5 cases presented with adrenal hyperplasia with left side adenomatoid solid lesion, 2 cases presented with adrenal hyperplasia with right side adenomatoid solid lesion, and 8 cases presented with double side adenomatoid solid lesion. The proportion of adrenal hyperplasia with unilateral cystic or calcified changes was 21.1%. Nine of the 19 patients underwent operation or fine needle biopsy. The pathology showed 7 adenomas (21-OHD/17α-OHD 5/2) and 2 myelolipomas (21-OHD/17α-OHD 1/1). Four patients were admitted into hospital because of the incidentaloma, while others because of the clinical symptoms. The average follow-up time was 31 months. CT images were rechecked among 7 patients. After the treatment, 1 patient's tumor shrunk, 4 cases had no recurrence, 1 case's tumor disappeared, and the other one case had no change. Symtoms of eleven followed-up patients relieved. Conclusions: The image of adrenal of CAH with adenomatoid adrenal gland is various. It may occur in each type of CAH presented as unilateral or bilateral, adenoma or myelolipoma.

Abstract
OBJECTIVE In order to detect the in vitro synergistic effect of 4 drugs-pasiniazid (PA), moxifloxacin, rifabutin and rifapentini on multidrug-resistant mycobacterium tuberculosis (MDR-MTB) and extensively drug-resistant mycobacterium tuberculosis(XDR-MTB), which were core drugs of"The program of retreatment research of tuberculosis". METHOD The checkerboard method was used to detect the minimum inhibitory concentration (MIC) of antituberculosis drug combination schemes (moxifloxacin-PA, moxifloxacin-PA-rifabutin and moxifloxacin-PA-rifapentini) to 40 strains of clinical drug resistant MTB(20 strains of MDR-MTB and 20 XDR-MTB) and the standard strain H37Rv, by calculating the fractional inhibitory concentration index of joint action in vitro to judge the combined effect, with fractional inhibitory concentration index(FICI)≤0.5 and FICI≤0.75 as the basis of 2 drugs and 3 drugs showing synergy. RESULTS The FICI of moxifloxacin-PA scheme for DR-MTB was 0.125 to 1.000, only 5 strains with a FICI ≤0.5, showing synergistic effect. The FICI of moxifloxacin-Pa-rifabutin scheme with 20 strains of MDR-MTB ranged from 0.310 to 1.260, 10 strains with a FICI≤0.75, showing synergistic effect. The FICI of moxifloxacin-PA-rifabutin scheme with 20 strains of XDR-MTB ranged from 0.215 to 1.250, 11 strains with a FICI≤0.75, showing synergistic effect. The FICI of moxifloxacin-PA-rifapentini scheme with 20 strains of MDR-MTB ranged from 0.150 to 0.780, 19 strains with a FICI≤0.75, showing synergistic effect. The FICI of moxifloxacin-PA-rifapentini scheme with 20 strains of XDR-MTB ranged from 0.200 to 1.280, 16 strains with a FICI≤0.75, showing synergistic effect. CONCLUSIONS The synergistic effect of moxifloxacin-PA scheme was poor, but showing better synergy when further combined with rifabutin or rifapentini. Rifabutin showed better effect than rifapentini, but the synergistic effect of moxifloxacin-PA-rifabutin combination scheme was poor than that of moxifloxacin-PA-rifapentini combination scheme.

Abstract
The purpose of this study was to evaluate single nucleotide polymorphism (SNP) variants of the estrogen receptor 1 gene (ESR1) at rs2234693 and rs9340799, as well as to investigate the relationship between ESR gene polymorphisms and postmenopausal osteoporosis (OP) of the spine in Chinese women. We recruited 198 postmenopausal women with OP and 276 healthy women between May 2012 and September 2015 in Zhongshan Hospital. Dual energy x-ray absorptiometry was used to measure the bone mineral density (BMD) of the lumbar vertebrae in all subjects. In addition, PCR-restriction fragment length polymorphism based analysis was conducted to identify the genotypes of ESR1. The distribution of ESR1 in the osteoporosis group and the control group was determined; the relationship between ESR polymorphisms and BMD was analyzed. The distributions of BMD were: TT < TC < CC, GG < AG < AA. The TT, TTGG, and TCGG genotypes were found to be lower as compared to the other genotypes. Stratified analysis suggested that the TT genotype and the combined genotypes TTGG and TCGG were significantly higher in the OP group as compared to the control group (P < 0.01). Therefore, ESR1 polymorphisms at rs2234693 and rs9340799 may be associated with OP, and could be used as markers to screen those with high risks to postmenopausal OP in Chinese women.

Abstract
In the presence of a perpendicular electric field, the low-energy electronic properties of the AB-stacked N-layer graphites with layer number N = 2, 3, and 4, respectively, are examined through the tight-binding model. The interlayer interactions, the number of layers, and the field strength are closely related to them. The interlayer interactions can significantly change the energy dispersions and produce new band-edge states. Bi-layer and four-layer graphites are two-dimensional semimetals due to a tiny overlap between the valence and conduction bands, while tri-layer graphite is a narrow-gap semiconductor. The electric field affects the low-energy electronic properties: the production of oscillating bands, the cause of subband (anti)crossing, the change in subband spacing, and the increase in band-edge states. Most importantly, the aforementioned effects are revealed completely in the density of states, e.g. the generation of special structures, the shift in peak position, the change in peak height, and the alteration of the band gap.

Abstract
AIMS To investigate the difference of urinary albumin excretion rate (UAER) and microalbuminuria (MAU) in various glucose tolerance subjects, especially between isolated-impaired glucose tolerance subjects and isolated-impaired fasting glycaemia subjects. METHODS A total of 2934 subjects were divided into five groups with various glucose tolerances, based on a 75-g oral glucose tolerance test. Microalbuminuria was defined when urinary albumin excretion rate was between 20 and 200 microg/min. RESULTS (i) The UAER in the newly diagnosed Type 2 diabetes mellitus group, impaired glucose tolerance/impaired fasting glycaemia group and isolated-impaired glucose tolerance group were all higher than that in the isolated-impaired fasting glycaemia group and normal glucose tolerance group, but it was comparable between isolated-impaired fasting glycemia group and normal glucose tolerance group. The prevalence of MAU and the odds ratio for MAU with adjustment for age and sex in various glucose tolerance groups showed the same trend as the UAER. (ii) After adjusting for age and sex, there is a significant association between logUAER and independent risk factors (partial correlation coefficients: r = 0.26 for 2-h post-challenge blood glucose, r = 0.26 for systolic blood pressure, r = 0.27 for diastolic blood pressure, r = 0.27 for body mass index and r = -0.13 for high density lipoprotein-cholesterol, all P < 0.001). The risks for MAU were 2-h post-challenge blood glucose, body mass index and diastolic blood pressure, while high density lipoprotein-cholesterol was protective. CONCLUSIONS The urinary albumin excretion rate and prevalence of microalbuminuria were higher in isolated-impaired glucose tolerance subjects than those in isolated-impaired fasting glycaemia subjects. At early abnormal glucose tolerance stage, the increasing post-challenge glycaemia might be a more important risk factor for urinary albumin excretion rate and microalbuminuria than increasing fasting glycaemia.

Abstract
The purpose of this study was to determine the interaction between free (unbound) and N-(2-hydroxypropyl) methacrylamide (HPMA) copolymer bound adriamycin and meso-chlorin e6 monoethylene diamine (Mce6) induced photodynamic therapy in combination in their cytotoxic activities against human ovarian epithelial carcinoma (OVCAR-3) in vitro. The effects of each agent (free drugs and HPMA copolymer bound) alone and in combination were measured simultaneously utilizing two measures of cell viability: a) mitochondrial respiration via the 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide reduction (MTT) assay; and b) thymidine incorporation via the tritiated thymidine incorporation (TI) assay. These were performed at 72 and 144 h after drug exposure. Forty-eight hours from time zero (24 h after drug addition), the cells treated with Mce6 (free and HPMA copolymer bound) and controls were exposed to 650 nm light (13 min at 15 mW/cm2, 11.7 J/cm2). The calculated ED50 values by the MTT 72 h assay for adriamycin (A) and Mce6/light (C) were 1.5 microg/ml and 209 ng/ml, respectively. Adriamycin demonstrated progressive cellular toxicity over time in both assays. Mce6/light demonstrated initial damage at 72 h by MTT and TI which recovered by 144 h. Adriamycin and Mce6/light acted cooperatively to increase the percentage of cells inhibited. In combination, 21.3+/-1.5% MTT reduction activity was observed by free adriamycin and Mce6/light compared to the expected 27+/-5% (p<0. 0001) based on additivity. Twice the ED50 of adriamycin (2A=3 microg/ml) or Mce6/light (2C=418 ng/ml) resulted in only 42+/-3.6% and 39.2+/-2.0% activity, respectively (both p<0.0001 vs. combination). When Mce6/light at 10x ED50 (10C) was combined with 1x ED50 of adriamycin (1A), or the reciprocal combination, additional cooperativity was demonstrated. Compared to free drugs, both HPMA copolymer bound adriamycin (P-A) and HPMA copolymer bound Mce6/light (P-C) required a 10-fold increase in drug concentration to show equivalency with free drugs (A or C). Dose response curves demonstrated a reduced slope compared to free drugs in the same dose ranges. When P-A was added (1-10x free adriamycin ED50) to an effective concentration of P-C (10P-C: equivalent to 10x free Mce6 ED50) an improved long-term inhibition of OVCAR-3 cell multiplication was noted in both the MTT and TI 144 h assays. P-C (1-10x free Mce6 ED50) added to an effective concentration of P-A (10P-A: equivalent to 10x free adriamycin ED50) did not appear to significantly improve the efficacy profile of P-A. A and C in vitro appear to act independently and are cooperative in their combined toxicity against the human ovarian epithelial carcinoma cell line OVCAR-3. HPMA copolymer-adriamycin and Mce6 conjugates (P-A and P-C, respectively) inhibited growth of OVCAR-3 in vitro. HPMA copolymer-adriamycin added to HPMA copolymer-Mce6 improved the efficacy of HPMA copolymer-Mce6.

Abstract
AIMS To evaluate the effect of metformin on glucose metabolism, insulin sensitivity and rate of conversion diabetes in people with impaired glucose tolerance (IGT). METHODS Seventy subjects with IGT were randomized under double-blind conditions to receive either placebo (n = 37) or metformin (n = 33) at a dosage of 250 mg three times daily for a duration of 12 months. Glycaemic control, plasma insulin and other biochemical indexes were assessed before and after 3, 6 and 12 months. RESULT At 12 months the conversion rate to diabetes was 16.2% in the placebo group compared to 3.0% for the metformin group (P = 0.011). Of subjects treated with metformin for 12 months, 84.9% became normoglycaemic compared to 51.4% of those receiving the placebo. Significant improvements in fasting glucose, glucose tolerance and insulin sensitivity were found at 12 months and at intermediate clinic assessments. CONCLUSIONS Metformin can improve glucose metabolism in IGT patients and may be a treatment option in their management of IGT subjects.

Abstract
The proton-sucrose symporter that mediates phloem loading is a key component of assimilate partitioning in many higher plants. Previous biochemical investigations showed that a diethyl pyrocarbonate-sensitive histidine residue is at or near the substrate-binding site of the symporter. Among the proton-sucrose symporters cloned to date, only the histidine residue at position 65 of AtSUC1 from Arabidopsis thaliana is conserved across species. To test whether His-65 is involved in the transport reaction, we have used site-directed mutagenesis and functional expression in yeast to determine the significance of this residue in the reaction mechanism. Symporters with mutations at His-65 exhibited a range of activities; for example, the H65C mutant resulted in the complete loss of transport capacity, whereas H65Q was almost as active as wild type. Surprisingly, the H65K and H65R symporters transport sucrose at significantly higher rates (increased Vmax) than the wild-type symporter, suggesting His-65 may be associated with a rate-limiting step in the transport reaction. RNA gel blot and protein blot analyses showed that, with the exception of H65C, the variation in transport activity was not because of alterations in steady-state levels of mRNA or symporter protein. Significantly, those symporters with substitutions of His-65 that remained transport competent were no longer sensitive to inactivation by diethyl pyrocarbonate, demonstrating that this is the inhibitor-sensitive histidine residue. Taken together with our previous results, these data show that His-65 is involved in sucrose binding, and increased rates of transport implicate this region of the protein in the transport reaction.

Abstract
PURPOSE A prospective study in 10 independent hospitals from 1992 to 1994 evaluated automated percutaneous lumbar discectomy (APLD) with a newly designed percutaneous instrument. MATERIALS AND METHODS One thousand five hundred eighty-two APLD procedures were performed in 1,525 patients with disc herniation or back pain. Mean follow-up after APLD was 18.3 months. Follow-up of at least 1 year was available in 1,474 patients. One thousand two hundred eighty-nine patients had sciatic pain and 185 had back pain only. Eight hundred twenty-two patients had symptoms for less than 2 years, 652 for more than 2 years. One thousand two hundred sixty-two patients were older than 60 years, 212 were younger than 60 years. Nine hundred fifty patients had disc protrusion, and 357 had sequestration. Forty-eight patients had disc or longitudinal ligament calcification. Twenty-two had previous surgical discectomy. All discectomies were done with use of a straight needle with the patient in the lateral decubitus position. RESULTS Success rate (measured by Hijikata's criteria) was 83% at 1 year. Success was significantly greater for protrusion versus sequestration (86% vs 72%, P < .001); for back pain alone versus leg and back pain (89% vs 80%, P < .005); for duration of symptoms less than 2 years versus more than 2 years (85% vs 79%, P < .005); and for age younger than 60 years versus older than 60 years (84% vs 76%, P < .01). Among postsurgical patients, success rate was 77% (17 of 22 patients). The only complication was discitis (0.06%, nine patients). Technical success at L5-S1 was 99% (795 of 800). CONCLUSION APLD with Teng's instrument has excellent results. Indications may include back pain alone. A straight needle can be used at L5-S1 in most patients, with proper positioning.

Abstract
This study characterizes the efficacy and toxicity of: (a) free Adriamycin and N-(2-hydroxypropyl) methacrylamide (HPMA) copolymer-Adriamycin conjugate (P-A); (b) free and HPMA copolymer-meso-chlorin e6 monoethylene diamine disodium salt (Mce6) conjugate (P-C) and light-induced photodynamic therapy; and (c) combinations of the HPMA copolymer conjugates (P-A and P-C) in the destruction of human epithelial ovarian carcinoma heterotransplanted in the nude mouse (OVCAR-3). Eight-week-old female nu/nu mice were injected in both flanks with 0.04-0.05 cm3 OVCAR-3 solid tumor dispersed in media. When bilateral tumors reached a minimum volume of 0.18 cm3 (one axis, 2.0-mm minimum) and demonstrated consistent growth, the experiments were initiated. Drugs were given i.v. unless otherwise noted. Tumor-bearing mice were allocated to the following protocols: (a) Adriamycin at 1 mg/kg, P-A at 30 mg/kg (2.2 mg/kg Adriamycin equivalent), and controls (n = 6 each); (b) Mce6 and light (2 h after administration: 650 nm light for 15 min to deliver 220 J/cm2) at 1.25, 2.5, 5, and 10 mg/kg (n = 6 each), 2.5 mg/kg i.p. (n = 4), and controls (n = 6); (c) P-C at 12.5, 25, and 75 mg/kg (1.5, 2.9, and 8.7 mg/kg Mce6 equivalent, respectively with light (18 h after administration; 650 nm light for 15 min to deliver 220 J/cm2), P-C at 25 mg/kg (2.9 mg/kg Mce6 equivalent) with no light administration, and controls (n = 7 each); and (d) a combination of P-A (30 mg/kg, 2.2 mg/kg adriamycin equivalent) and P-C (12.5 and 75 mg/kg, 1.5 mg/kg and 8.7 mg/kg Mce6 equivalent, respectively) with and without light (n = 7 each; 18 h after administration; 650 nm light for 15 min to deliver 220 J/cm2) and controls (n = 12). Tumor volumes and animals weights were assessed for significant differences from the treated and controls groups by Student's t test. Adriamycin (1 mg/kg) and P-A (30 mg/kg. 2.2 mg/kg Adriamycin equivalent) caused less than a 10% weight loss, and treated tumor volumes (day 10-32) were significantly less than those of controls (all P < 0.045). Mce6 (2.5-10 mg/kg i.v.), caused tumor regression in 80% of tumors and a shock syndrome in 17-83%. i.p. dosing (2.5 mg/kg) was uniformly fatal. Mce6 at 1.25 mg/kg did not show reproducible efficacy. P-C with light (25 and 75 mg/kg, 2.9 and 8.7 mg/kg Mce6 equivalent, respectively) demonstrated significant tumor destruction (P < 0.003) but not complete ablation. The combinations of P-A (30 mg/kg, 2.2 mg/kg Adriamycin equivalent) plus P-C (12.5 and 75 mg/kg; 1.5 mg/kg and 8.7 mg/kg of Mce6 equivalent, respectively) with light resulted in tumor volumes that were significantly less than control tumor volumes and the tumor volumes of mice receiving either P-A (30 mg/kg, 2.2 mg/kg Adriamycin equivalent) or P-C with light (12.5 or 75 mg/kg. 1.5 or 8.7 mg/kg Mce6 equivalent, respectively) alone (all P < 0.02). P-C (75 mg/kg, 8.7 mg/kg Mce6 equivalent) added to P-A (30 mg/kg, 2.2 mg/kg Adriamycin equivalent) resulted in complete tumor ablation. Free Mce6 demonstrates a narrow margin of safety, which is extended by incorporation into HPMA copolymers. P-A demonstrates safety and efficacy in vivo. The combined chemotherapy and photodynamic therapy of P-A (30 mg/kg, 2.2 mg/kg Adriamycin equivalent) with P-C and light (12.5 and 75 mg/kg 1.5 and 8.7 mg/kg Mce6 equivalent, respectively) was nontoxic and allowed us to attain a significant improvement in tumor cures than those obtained by P-A or P-C with light alone.

Abstract
The aim was to determine the burden of diabetes mellitus (DM) in an urban area of China to aid us in planning preventive measures for those at risk of DM. A survey was conducted among the 29,859 subjects aged between 30 and 64 belonging to 32 units of the Shougang Corporation (a heavy industry enterprise) within the Beijing area. WHO study protocols and diagnostic criteria were used to determine the prevalence of DM and impaired glucose tolerance (IGT). The results showed that the age-adjusted prevalence of DM and impaired glucose tolerance (IGT) was 3.63% and 4.19%, respectively, both increasing with age. Peak prevalence for both occurred in the 60-64 age group. Prevalence showed no difference between the sexes in DM but was higher for females in IGT. Obesity, being overweight, a family history of diabetes mellitus and in women, a history of delivering babies with macrosomia, all correlated closely with the prevalence of DM and IGT. High protein intake was also associated with DM, Smoking had no effect on either DM or IGT. Intellectual workers had a higher incidence of IGT than manual workers. Seventy per cent DM was undiagnosed prior to the survey. This survey, done according to the recommendation of WHO, and including appropriate adjustments, reflects the growing prevalence of DM and IGT in this population. It can be compared with other studies for epidemiological analysis.

Abstract
The effects of Arctium lappa L. (root) on anti-inflammatory and free radical scavenger activity were investigated. Subcutaneous administration of A. lappa crude extract significantly decreased carrageenan-induced rat paw edema. When simultaneously treated with CCl4, it produced pronounced activities against CCl4-induced acute liver damage. The free radical scavenging activity of its crude extract was also examined by means of an electron spin resonance (ESR) spectrometer. The IC50 of A. lappa extract on superoxide and hydroxyl radical scavenger activity was 2.06 mg/ml and 11.8 mg/ml, respectively. These findings suggest that Arctium lappa possess free radical scavenging activity. The inhibitory effects on carrageenan-induced paw edema and CCl4-induced hepatotoxicity could be due to the scavenging effect of A. lappa.

Abstract
We have developed a rapid and simple PCR-based method which is modified from the mutagenically separated polymerase chain reaction (MS-PCR) to detect the molecular defects of beta-thalassaemia. We can use this technique to amplify normal and mutant alleles of the beta-globin gene in the same reaction tube, using different-sized allele-specific primers. This mutagenesis separates the amplification reactions of alleles performed in the same tube. Subsequent gel electrophoresis shows at least one of the two allelic products at the same locus or at least two of the several allelic products at different loci. Therefore, in addition to simple handling, MS-PCR provides a within-assay quality control for the exclusion of false negative results. The five most common mutations of beta-thalassaemia and haemoglobin E which occur in the Taiwanese population were tested, and 14 prenatal samples were checked with accurate results. This method is simple, rapid and accurate, and can be used routinely in prenatal diagnosis. The principle used here can also be applied to other genetic diseases.

Abstract
OBJECTIVE Considering the differing mechanisms of cytotoxicity produced by adriamycin and the photosensitizer meso-chlorin e6 monoethylene diamine (Mce6) with light, the interaction of these agents in combination on human ovarian epithelial carcinoma (OVCAR-3 in vitro) was evaluated by dose and effect addition isobole analysis. METHODS Mitochondrial respiration via the 3-(4,5-dimethyl thiazol-2 yl)-2,5-diphenyl tetrazolium bromide cleavage assay (MTT) and reproductive capacity via the tritiated thymidine incorporation assay (TI) were assessed 72 and 144 hours after exposure to adriamycin, Mce6, and light (650 nm), and to their combinations, in OVCAR-3 cells grown in vitro (20,000 cells per well). RESULTS In the majority of assays, reproductive capacity was more sensitive to the drug(s) than was mitochondrial respiration (2-10x). Dose-addition isobole analysis showed synergy for the combination of 50% median effective dose (ED50) adriamycin with 50% ED50 Mce6/light in all assays (all P < or = .027). Antagonism was noted with the combination 25% ED50 adriamycin with 75% ED50 Mce6/light. Additivity and synergy were the predominant interactions for 75% ED50 adriamycin with 25% ED50 Mce6/light by dose-addition isobole analyses. Effect-addition isoboles showed a predominance of synergy, particularly for the combination 50% ED50 adriamycin with 50% ED50 Mce6/light. CONCLUSION Synergy and additivity are the primary in vitro interactions for the combination of adriamycin and Mce6/light in the dosage range tested. Reproductive capacity is more sensitive to these agents than is mitochondrial respiration.

Abstract
Pituitary enlargement was detected on CT scanning in 10 of 17 patients with primary hypothyroidism before thyroid hormone replacement therapy. The serum prolactin levels were slightly elevated in patients with pituitary enlargement. After replacement therapy with thyroid tablet, the enlarged pituitary glands were returned to normal in 6 patients when they were in euthyroid, while another patient's pituitary was still enlarged for inadequate dose of thyroid tablet. In conclusion, pituitary enlargement was frequently seen in patients with primary hypothyroidism and can be restored to normal after effective treatment with thyroid hormones.

Abstract
It is well known that growth hormone (GE) secretion and regulation in diabetics are abnormal. In order to evaluate the response of GH to nonphysiological stimuli in diabetics, a thyrotropin-releasing hormone (TRH) test (500 micrograms by IV bolus injection) was carried out in 12 patients with insulin-dependent diabetes (IDD, 6 males and 6 females). 11 noninsulin-dependent diabetes (NIDD, 5 males and 6 females), and 10 normal controls (6 males and 4 females). The results showed that the basal serum GH levels in diabetics were higher than that in normal controls and it was even higher in IDD than in NIDD. Following the TRH stimulus, the mean peak level of GH in IDD was the highest among the three groups, the differences being statistically significant (F = 9.323, P less than 0.01). It was concluded that a nonspecific response to TRH of GH did occur in IDD, and the peak values were even higher in female than in male subjects. A negative correlation existed between the GH peak values and the age of the patients as well as in the controls. This supported the view that GH responsiveness to TRH has a tendency of progressive decline with age. However, no significant correlation was found between the peak value of GH and the blood glucose level or the microangiopathic complications. The mechanism of TRH stimulation on GH release in diabetics is discussed.

Abstract
Growth hormone (GH) secretion is mediated by hypothalamic factors, mainly growth hormone releasing factor (GRF) and somatostatin (SS). The hypothalamic hormones, under direct neurotransmitter control, stimulate GH secretion through different central mechanisms. Atropine, an anticholinergic agent, can cross the blood-brain barrier and inhibit GH secretion stimulated by exercise and sleep in normal persons. In order to study the inhibiting effect of atropine on GH release and whether glucose can be replaced by atropine, normal persons and acromegaly patients were observed during exercise, after atropine, and 100 g glucose loading. The results confirmed that GH secretion increases after exercise and that this GH elevation can be inhibited by atropine in normal subjects. But in acromegaly patients high basal GH levels can not be inhibited by 100 g glucose loading or 0.6 mg atropine during the active phase of the disease. Blood sugar levels remained unchanged during the atropine test. It is suggested that the atropine test can be used as a GH inhibitory test in acromegaly patients with overt diabetes.
