Abstract
BACKGROUND/AIM In this study, we used an orthotropic breast cancer model combined with ketamine addiction and next-generation sequencing (NGS) to comprehensively investigate molecular alterations in ketamine-mediated metastasis. Ketamine is widely used in anesthesia and drug abuse. Our previous study revealed that ketamine promotes the growth of breast cancer cells; however, the detailed molecular mechanism remains unknown. MATERIALS AND METHODS An orthotropic breast cancer model was established by injecting EO771 breast cancer cells into the mammary fat pad of mice intraperitoneally administered ketamine (30 mg/kg, daily) for 68 days. Tumors collected at day 38 were frozen for future analysis, and their metastasis state was checked at day 68. RESULTS Tumors were grouped and subjected to NGS analysis, followed by differential gene expression analysis (DEseq) and pathway identification. DEseq analysis showed that ketamine up-regulated metastasis-related signaling, and the key genes were BMP5, FZD6, MMP1B, EGFR, WNT5A, BMP7, and DCN. CONCLUSION Ketamine addiction up-regulates the expression of genes involved in the Wnt, EGFR, and BMP signaling cascades, which may be associated with breast cancer progression and metastasis.

Abstract
BACKGROUND Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder characterized by a combination of capillary malformations, soft-tissue or bone hypertrophy, and varicose veins or venous malformations. The syndrome predisposes patients to hypercoagulable states, including venous thromboembolism and pulmonary embolism (PE).
CASE SUMMARY A 12-year-old girl with KTS was scheduled excision of verrucous hyperkeratosis in the left foot and posterior aspect of the left leg and left thigh and excision of a cutaneous hemangioma in the right buttock. After induction, the surgeon elevated the patient’s leg for sterilization, whereupon she experienced a massive PE and refractory cardiac arrest. Extracorporeal membrane oxygenation (ECMO) was performed after prolonged resuscitation, and she had a return of spontaneous circulation. After this episode, the patient was discharged without any neurologic complications.
CONCLUSION The mechanism of PE, a lethal disease, involves a preexisting deep vein thrombosis that is mechanically dislodged by compression or changing positions and travels to the pulmonary artery. Therefore, patients predisposed to PE should be prescribed prophylactic anticoagulants. If the patient has unstable vital signs, resuscitation should be started immediately, and extracorporeal cardiopulmonary resuscitation should be considered in settings with existing ECMO protocols, expertise, and equipment. Awareness of PE in patients with KTS while leg raising for sterilization is critical.

Abstract
Epidural analgesia is a suitable and effective treatment for labor pain. However, the preferable modality setting for delivery remains debatable. This study adopted a programmed intermittent epidural bolus (PIEB) setting in conjunction with a patient-controlled epidural analgesia (PCEA) setting to improve the quality of labor analgesia and reduce the number of medical staff. We conducted a prospective observational analysis of primigravida parturients scheduled for spontaneous labor, which required epidural analgesia for painless labor. A total of 483 healthy primigravida parturients with singleton pregnancies were included in this cohort; 135 nulliparous patients were assigned to the continuous infusion setting (CEI) group and 348 to the PIEB + PCEA group. Compared to the CEI setting, the PIEB + PCEA setting significantly reduced the manual rescue by the clinician, extended the time required for the first manual rescue dose, and acclaimed good maternal satisfaction. The use of the CEI mode increased for poor performance requiring more than two rescues with an odds ratio of 2.635 by a binary logistic regression analysis. Using the PIEB + PCEA setting as the maintenance infusion had a longer duration for the first requested manual rescue, fewer manual rescue boluses, excellent satisfaction, and no significant increase in adverse events compared to the CEI setting.

Abstract
Over the past few decades, mechanisms of programmed cell death have attracted the scientific community because they are involved in diverse human diseases. Initially, apoptosis was considered as a crucial mechanistic pathway for programmed cell death; recently, an alternative regulated mode of cell death was identified, mimicking the features of both apoptosis and necrosis. Several lines of evidence have revealed that dysregulation of necroptosis leads to pathological diseases such as cancer, cardiovascular, lung, renal, hepatic, neurodegenerative, and inflammatory diseases. Regulated forms of necrosis are executed by death receptor ligands through the activation of receptor-interacting protein kinase (RIPK)-1/3 and mixed-lineage kinase domain-like (MLKL), resulting in the formation of a necrosome complex. Many papers based on genetic and pharmacological studies have shown that RIPKs and MLKL are the key regulatory effectors during the progression of multiple pathological diseases. This review focused on illuminating the mechanisms underlying necroptosis, the functions of necroptosis-associated proteins, and their influences on disease progression. We also discuss numerous natural and chemical compounds and novel targeted therapies that elicit beneficial roles of necroptotic cell death in malignant cells to bypass apoptosis and drug resistance and to provide suggestions for further research in this field.

Abstract
BACKGROUND This study determined whether sugammadex was associated with a lower risk of postoperative pulmonary complications and improved outcomes in lung surgeries. METHODS A systematic literature search was conducted using PubMed, Embase, Web of Science, and the Cochrane Library from January 2000 to March 2022. The characteristics of lung surgeries using sugammadex treatment compared with control drugs and postoperative outcomes were retrieved. The primary outcome was estimated through a pooled odds ratio (OR) and its 95% confidence interval (CI) was identified using a random-effects model. RESULTS From 465 citations, 7 studies with 453 patients receiving sugammadex and 452 patients receiving a control were included. The risk of postoperative pulmonary complication (PPCs) was lower in the sugammadex group than in the control group. Also, it showed that the effect of sugammadex on PPCs in the subgroup analysis was significantly assessed on the basis of atelectasis or non-atelectasis. Furthermore, subgroup analysis based on the relationship between high body mass index (BMI) and PPCs also showed that sugammadex had less occurrence in both the high BMI (defined as BMI ≥ 25) and low BMI groups. No difference in length of hospital stay (LOS) between the two groups was observed. CONCLUSION This study observed that although reversing neuromuscular blockages with sugammadex in patients undergoing thoracic surgery recorded fewer PPCs and shorter extubation periods than conventional reversal agents, no difference in LOS, postanaesthesia care unit (PACU) stay length and chest tube insertion duration in both groups was observed.

Abstract
Purpose This meta-analysis of all relevant clinical trials investigated surgical plethysmographic index (SPI)-guided analgesia’s efficacy under general anesthesia for perioperative opioid requirement and emergence time after anesthesia. Methods PubMed, Embase, Web of Science, and Cochrane Library were searched up to January 2022 to identify clinical trials comparing SPI-guided and conventional clinical practice for patients who underwent general anesthesia. With the random-effects model, we compared intraoperative opioid consumption, emergence time, postoperative pain, analgesia requirement, and incidence of postoperative nausea and vomiting (PONV). Results Thirteen randomized controlled trials (RCTs) (n = 1314) met our selection criteria. The overall pooled effect sizes of all RCTs indicated that SPI-guided analgesia could not significantly reduce opioid consumption during general anesthesia. SPI-guided analgesia accompanied with hypnosis monitoring could decrease intraoperative opioid consumption (standardized mean difference [SMD] − 0.31, 95% confidence interval [CI] − 0.63 to 0.00) more effectively than SPI without hypnosis monitoring (SMD 1.03, 95% CI 0.53–1.53), showing a significant difference (p < 0.001). SPI-guided analgesia could significantly shorten the emergence time, whether assessed by extubation time (SMD − 0.36, 95% CI − 0.70 to − 0.03, p < 0.05, I2 = 67%) or eye-opening time (SMD − 0.40, 95% CI − 0.63 to − 0.18, p < 0.001, I2 = 54%). SPI-guided analgesia did not affect the incidence of PONV, postoperative pain, and analgesia management. Conclusion SPI-guided analgesia under general anesthesia could enhance recovery after surgery without increasing the postoperative complication risk. However, it did not affect intraoperative opioid requirement. Notably, SPI-guided analgesia with hypnosis monitoring could effectively reduce intraoperative opioid requirement.

Abstract
Non-medical use of ketamine as an adulterant to ecstasy is more prevalent than amphetamine in Taiwan. Ketamine's effect on immunosuppression might play some functional role in tumor growth, while it is still controversial whether ketamine abuse could increase tumor growth or not. This study aimed to investigate the influence of ketamine addiction in breast tumors and related gene expressions. The effect of ketamine treatment on proliferation, colony formation, migration, and invasion of triple-negative breast cancer cell line EO771 was examined. In addition, a ketamine addiction mice model was established by intraperitoneal injection (IP) of ketamine in mice and used to investigate the effects of ketamine addiction on tumor growth and the possible mechanisms. In the in vitro studies, ketamine treatment at different concentrations did not affect EO771 cell proliferation and colony formation. But ketamine did enhance migration and invasion of EO771 cells. The in vivo experiments showed significantly increased breast tumor volume and weight in ketamine-addicted mice than in normal saline groups. miR-27b-3p level, human epidermal growth factor receptor 2 (HER2), and epidermal growth factor receptor (EGFR) significantly increased in tumors of ketamine addiction mice compared to control mice. In vivo evidence showed that Ketamine might increase tumor growth on the tumor microenvironment, and miR-27b-3p, HER2, and EGFR might play a role in the process.

Abstract
Background: Acute lung injuries (ALI) cause disruption of the alveolar-capillary barrier and is the leading cause of death in critically ill patients. This study tested the hypothesis that the administration of freshly isolated viable allogeneic mitochondria can prevent alveolar-capillary barrier injuries at the endothelial level, as mitochondrial dysfunction of the pulmonary endothelium is a critical aspect of ALI progression. Methods: ALI was induced by intratracheal lipopolysaccharide instillation (LPS, 1mg/kg) in anesthetized rats. Mitochondria (100 µg) were isolated from the freshly harvested soleus muscles of naïve rats and stained with a green fluorescence MitoTracker™ dyne. A mitochondria or placebo solution was randomly administered into the jugular veins of the rats at 2 h and 4 h after ALI induction. An arterial blood gas analysis was done 20 h later. The animals were then sacrificed and lung tissues were harvested for analysis. Results: An IVIS Spectrum imaging system was used to obtain ex vivo heart-lung block images and track the enhancement of MitoTracker™ fluorescence in the lungs. Mitochondria transplantation significantly improved arterial oxygen contents (PaO2 and SaO2) and reduced CO2 tension in rats with ALI. Animals with mitochondrial transplants had significantly higher ATP concentrations in their lung tissues. Allogeneic mitochondria transplantation preserved alveolar-capillary barrier function, as shown by a reduction in protein levels in the bronchoalveolar lavage fluid and decreased extravasated Evans blue dyne and hemoglobin content in lung tissues. In addition, relaxation responses to acetylcholine and eNOS expression were potentiated in injured pulmonary arteries and inflammatory cells infiltration into lung tissue was reduced following mitochondrial transplantation. Conclusions: Transplantation of viable mitochondria protects the integrity of endothelial lining of the alveolar-capillary barrier, thereby improving gas exchange during the acute stages of endotoxin-induced ALI. However, the long-term effects of mitochondrial transplantation on pulmonary function recovery after ALI requires further investigation.

Abstract
Objective: To evaluate the effect of daily average temperature on the atteck of allergic rhinitis (AR) by analyzing the changes of the outpatient visits of AR in Lanzhou. Methods: The meteorological and air pollution data of Lanzhou City and the outpatient visits of AR in Departments of Otorhinolaryngology and head and neck surgery of The First Hospital of Lanzhou University, The Second Hospital of Lanzhou University and Gansu Provincial People's Hospital from 2013 to 2017 were collected to describe the meteorological factors, air pollutants and the outpatient visits of AR. The correlation among the three factors was then analyzed by Spearman rank correlation analysis. Using the distributed lag non-linear model, the relationship between daily average temperature and the number of daily outpatient visits of AR was studied and stratified by gender and age with the long-term trend, seasonal trend and other confounding factors controlled. Results: From 2013 to 2017, the outpatient visits of AR in the above three hospitals reached 20 008 person times. Daily average temperature in Lanzhou showed a non-linear correlation to the outpatient visits of AR, with a certain lag effect. When the daily average temperature was 22 ℃ and the cumulative lag was 21 days (lag 0-21 d), the relative risk (RR) peaked at 4.851 (95%CI: 3.986-5.904). The effect of relatively low temperature (2.3 ℃, P25), relatively high temperature (19.8 ℃, P75) and high temperature (25.5 ℃, P95) on lag 0-21 d were the highest, which were 1.761 (95%CI: 1.375-2.255), 4.299 (95%CI: 3.574-5.171) and 3.656 (95%CI: 3.046-4.389), respectively. According to the stratified analysis, low and relatively low temperature had more significant effect on the outpatient visits of AR among women and people aged 0-14 years. When lag was 0-21 days, the RR value of low temperature for female outpatient visits of AR was 1.433 (95%CI: 1.105-1.860); the RR value of relatively low temperature for female outpatient visits of AR was 1.879 (95%CI: 1.460-2.419); the RR value of low temperature for AR outpatient visits for people aged 0-14 years was 1.511 (95%CI: 0.999-2.287), the RR value of relatively low temperature for AR outpatient visits for people aged 0-14 years was 2.051 (95%CI: 1.383-3.042). Relatively high temperature, on the other hand, had a more significant effect on men and people aged 15-59 years. High temperature had a greater impact on the number of AR outpatients in men and people aged 0-14 years. Conclusions: Temperature may be an important influencing factor of AR onset in Lanzhou. At relatively high temperature (19.8 ℃), the risk of AR outpatient visits is significantly increased, and the cumulative lagged effects are observed. The sensitivity of AR patients to temperature is different in different genders and ages.

Abstract
BACKGROUND Risk of postoperative nausea and vomiting (PONV) is usually high among patients undergoing laparoscopic sleeve gastrectomy (LSG). Perioperative hemodynamic optimization using goal-directed fluid therapy (GDFT) based on stroke volume variation (SVV) has been suggested to reduce PONV. OBJECTIVES This study aimed to investigate the effectiveness of GDFT on reducing PONV. SETTING The operating rooms in China Medical University Hospital. METHODS This prospective cohort study included 75 patients undergoing LSG. Patients were randomized into 3 groups: controls (conventional fluid therapy), GDFT-hydroxyethyl starch (GH), and GDFT-lactated Ringer's (GL) groups. In both GDFT groups, optimization of fluid administration was achieved by continuous monitoring and adjusting of SVV. Severity of PONV was evaluated using a standardized questionnaire. Other clinically relevant events, including in-hospital surgical site infections and length of hospital stay were also investigated. RESULTS In the GH group, the total volume of fluid administered intraoperatively was significantly lower than that in the GL and control groups (P < .001). Assessment of PONV severity showed a significantly higher score at postoperative 24 hours in the GH group (P < .05), while no significant differences were found between the 3 groups at postoperative 48 hours. No significant differences were observed between the 3 groups in surgical site infections and length of hospital stay. CONCLUSION No significant benefit is found in reducing PONV by using GDFT in patients undergoing LSG, although GDFT effectively avoids excessive volume of fluid administration. PONV incidence appears to be higher with intraoperative colloid infusion for GDFT during LSG. Further investigation is warranted to elucidate the mechanism underlying PONV in postoperative LSG.

Abstract
Long non-coding RNAs (lncRNAs) are increasingly recognized as promising targets in cancer treatment. However, compared to targeting the ordinary protein-coding genes, suppressing non-coding RNAs expressed in cancer cells has been a more challenging task. The major hurdles lay on the requirement of a tumor-specific delivery system for the designated inhibitor to suppress the target transcripts within the cellular compartment. EGFR is a cancer driver gene which is frequently associated with the triple-negative phenotype of breast cancer. Prior studies have shown that expression of the tumor-promoting lncRNA HOTAIR (HOX antisense intergenic RNA) is positively regulated by the epithelial growth factor receptor (EGFR) in triple-negative breast cancer (TNBC), and consistently the expression of both genes is closely correlated in breast cancer. Here we show that a chimeric aptamer recognizing the epithelial growth factor receptor (EGFR) coupled with a siRNA against HOTAIR (EGFR aptamer-coupled siHOTAIR) preferentially and effectively down-regulated HOTAIR in EGFR-expressing cancer cells. Functionally, the EGFR aptamer-coupled siHOTAIR more potently inhibited the growth, migration, and invasion of EGFR-expressing TNBC cells as well as cells with reconstituted EGFR compared to cancer cells with low EGFR expression. Our results demonstrate a novel strategy of targeting cancer progression by aptamer-directed delivery of anti-lncRNA RNA interference that can be applicable to other cellular contexts and cancer types.

Abstract
Autophagy, an important cellular homeostatic mechanism regulates cell survival under stress and protects against acute kidney injury. However, the role of long noncoding RNA (lncRNA) in autophagy regulation in renal tubular cells (HK-2) is unclear. The study was aimed to understand the importance of lncRNA in hypoxia-induced autophagy in HK-2 cells. LncRNA eosinophil granule ontogeny transcript (EGOT) was identified as autophagy-associated lncRNA under hypoxia. The lncRNA EGOT expression was significantly downregulated in renal tubular cells during hypoxia-induced autophagy. Gain- and loss-of-EGOT functional studies revealed that EGOT overexpression reduced autophagy by downregulation of ATG7, ATG16L1, LC3II expressions and LC 3 puncta while EGOT knockdown reversed the suppression of autophagy. Importantly, RNA-binding protein, (ELAVL1)/Hu antigen R (HuR) binds and stabilizes the EGOT expression under normoxia and ATG7/16L1 expressions under hypoxia. Furthermore, HuR mediated stabilization of ATG7/16L1 expressions under hypoxia causes a decline in EGOT levels and thereby promotes autophagy. Altogether, the study first reveals the functional interplay of lncRNA EGOT and HuR on the posttranscriptional regulation of the ATG7/16L1 expressions. Thus, the HuR/EGOT/ATG7/16L1 axis is crucial for hypoxia-induced autophagy in renal tubular cells.

Abstract
Objective: To explore the effect of 18β-sodium glycyrrhetinic acid on thymic stromal lymphopoietin (TSLP) in nasal mucosa of allergic rhinitis (AR) rats. Methods: One hundred Wistar rats,half male and half female,were randomly divided into 5 groups by random number table method: control group, AR model group,budesonide group,18β-sodium glycyrrhetinic acid at dose of 20 mg/kg and 40 mg/kg groups, with 20 rats in each group. AR animal models were established by ovalbumin (OVA) sensitization in the other four experimental groups. After successful modeling, budesonide and 18β-sodium glycyrrhetinic acid were given in each group,and the detection time points were 2 weeks and 4 weeks. The distribution of TSLP in rat nasal mucosa was detected by immunohistochemistry,and the expression of TSLP in rat nasal mucosa was determined by Western blot at the protein level. The expression of TSLP-mRNA in rat nasal mucosa was detected and compared by real-time fluorescence quantitative PCR (RT-PCR) at mRNA level. The concentrations of IL-4 and OVA-sIgE in rat serum were measured and compared by ELISA. One-way analysis of variance and the least significant difference method were used for the comparison among groups, LSD t test was used for the comparison between the two groups,and the difference was statistically significant (P<0.05). Results: Immunohistochemistry confirmed existence of TSLP in rat nasal mucosa, especially in epithelial cells,endothelial cells and epithelial cilia. Western blot and RT-PCR suggested that the expression of TSLP and TSLP-mRNA in nasal mucosa of AR model group was significantly higher than that of control group (2 weeks TSLP: 1.795 9±0.131 4 vs 0.990 5±0.164 2, 4 weeks TSLP: 1.809 7±0.253 4 vs 0.870 3±0.124 4; 2 weeks TSLP-mRNA:4.582 9±0.697 7 vs 1.108 7±0.081 1, 4 weeks TSLP-mRNA:4.814 4±0.662 8 vs 1.001 0±0.155 3; all P<0.05). After 2 weeks and 4 weeks of drug intervention,the expression of TSLP and TSLP-mRNA was inhibited in nasal mucosa of budesonide group,18β-sodium sodium glycyrrhetinic acid at dose of 20 mg/kg and 40 mg/kg group,which was significantly different from that of AR model group (2 weeks TSLP: (0.897 8±0.081 8)/(1.072 1±0.113 6)/(1.396 6±0.133 9) vs 1.795 9±0.131 4; 4 weeks TSLP: (1.191 0±0.161 3)/(1.141 0±0.152 3)/(1.200 5±0.189 6) vs 1.809 7±0.253 4; 2 weeks TSLP-mRNA: (1.175 6±0.100 9)/(1.254 4±0.078 2)/(2.037 2±0.559 2) vs 4.582 9±0.697 7; 4 weeks TSLP-mRNA: (1.158 3±0.104 3)/(1.224 0±0.034 0)/(1.275 2±0.099 6) vs 4.814 4±0.662 8; all P<0.05), and not significantly different from control group. With the inhibition of TSLP, the concentrations of IL-4 and OVA-sIgE in rat serum were also decreased. Conclusion: 18β-sodium glycyrrhetinic acid has obvious inhibitory effect on TSLP in nasal mucosa of AR rats, which can control Th2 type immune inflammatory reaction.

Abstract
Objective:To observe the effect of 18β-sodium glycyrrhetinic acid(18β-SGA) on the expression of TNF-α in nasal mucosa of rats with allergic rhinitis(AR), and explore the intervention mechanism of 18β-SGA on AR. Method:One hundred and six SPF-level Wistar rats were randomly divided into control group, AR group, budesonide group, 18β-SGA low dose group and high dose group. After the AR rat model was constructed by ovalbumin, the rats were given drug intervention and sacrificed after 2 and 4 weeks of intervention. The nasal mucosa of the rats was taken for immunohistochemical staining, RT-qPCR and Western-blotting to localize and quantify the expression of TNF-α. Result:By immunohistochemistry, Western-blotting and RT-PCR, TNF-α was mainly found in the columnar epithelium, vascular endothelium, glandular and some inflammatory cytoplasm of nasal mucosa. And the expression of TNF-α in the nasal mucosa of AR rats was significantly increased than the normal group at the protein and mRNA levels (P<0.01). After intervention with different doses of 18β-SGA, the expression of TNF-α was significantly decreased (P<0.01), especially after 4 weeks of 18β-SGA low dose group(P<0.01). Conclusion:Different doses of 18β-SGA have therapeutic effects on AR, and its mechanism of action may be related to the inhibition of TNF-α expression.

Abstract
Casticin, a polymethoxyflavone derived from natural plants, has biological activities including induction of cell apoptosis. In this study, we showed the beneficial effects of casticin on the inhibition of prostate cancer cell metastasis. Casticin reduced total viable cell number, thus, we selected low doses of casticin for following experiments. Casticin decreased cell mobility, suppressed cell migration and invasion, and reduced cell gelatinolytic activities of MMP-2/-9. Furthermore, casticin inhibited the protein levels of AKT, GSK3 αβ, Snail, and MMPs (MMP-2, -9, -13, and -7) at 24 and 48 hr treatment. Casticin diminished the expressions of NF-κB p65, GRB2, SOS-1, MEK, p-ERK1/2, and p-JNK1/2 at 48 hr treatment only. However, casticin reduced the level of E-cadherin at 24 hr treatment but elevated at 48 hr. The novel findings suggest that casticin may represent a new and promising therapeutic agent for the metastatic prostate cancer. PRACTICAL APPLICATIONS: Casticin derived from natural plants had been used for Chinese medicine in Chinese population for thousands of years. In the present study, casticin attenuated metastatic effects, including decreasing viable cell number, inhibiting the migration, invasion, and adhesion, and reducing matrix metalloproteinases activity on human prostate DU 145 cancer cells. In addition, the results also provided possible pathways involved in casticin anti-metastasis mechanism. We conclude that casticin may be an aptitude anticancer agent or adjuvant for the metastatic prostate cancer in the future.

Abstract
Casticin, derived from Fructus Viticis, has anticancer properties in many human cancer cells, however, there is no report to show that casticin promotes immune responses and affects the survival rate of leukemia mice in vivo. The aim of this study is to evaluate the effects of casticin on immune responses and the survival rate of WEHI-3 cells generated in leukemia mice in vivo. Animals were divided into six groups: normal control mice, leukemia control mice, mice treated with ATRA (all-trans retinoic acid), and casticin (0.1, 0.2, and 0.4[Formula: see text]mg/kg) treated mice. All animals were treated for 14 days and then measured for body weights, total survival rate, cell markers, the weights of liver and spleen, phagocytosis of spleen cells, NK cell activities and cell proliferation. Results show that casticin did not affect animal appearances, however, it increased body weights and decreased the weights of liver at 0.2[Formula: see text]mg/kg and 0.4[Formula: see text]mg/kg treatment. Casticin also decreased spleen weight at 0.2[Formula: see text]mg/kg and 0.4[Formula: see text]mg/kg treatment, increased CD3 at 0.1, 0.2 and 0.4[Formula: see text]mg/kg doses and increased CD19 at 0.2[Formula: see text]mg/kg treatment but decreased CD11b and Mac-3 at 0.1, 0.2 and 0.4[Formula: see text]mg/kg treatment. Casticin (0.1, 0.2 and 0.4[Formula: see text]mg/kg) increased macrophage phagocytosis from PBMC (peripheral blood mononuclear cell) and peritoneal cavity. Furthermore, casticin increased NK cells’ cytotoxic activity and promoted T cell proliferation at 0.1–0.4[Formula: see text]mg/kg treatment with or without concanavalin A (Con A) stimulation, but only increased B cell proliferation at 0.1 mg/kg treatment. Based on these observations, casticin could be used as promoted immune responses in leukemia mice in vivo.

Abstract
Three cases of internal carotid artery (ICA) injury during endoscopic endonasal surgery were analyzed, including 1 case of recurrent malignancy of sphenoid sinus, 1 case of intraorbital meningioma and 1 case of optic neuropathy. Salvage sphenoid sinus packing with gauze strip was managed in all the three cases. One patient operated a permanent closure of the carotid system intraoperatively and died after surgery. Among 2 survival cases, one patient accepted the endovascular embolization subsequently; the other patient was cured by intravaseular stent graft implantation without craniocerebral or ocular complicatitms.

Abstract
Benign prostatic hyperplasia (BPH) is a common disorder in the aging male population. Despite evidence that thyroid status impacts the prostate, the objective of this study was to examine whether patients with hyperthyroidism were at a greater risk for BPH.This study is a retrospective nationwide population-based cohort study of the Chinese population. Data for this study were retrieved from the Taiwan National Health Insurance Research Database (NHIRD). Overall, 1032 male patients aged 40 years or older with hyperthyroidism diagnosed between 2000 and 2006 were included in the hyperthyroidism group, and 4128 matched controls without hyperthyroidism were included in the non-hyperthyroidism group. Both groups were monitored until the end of 2011. A Cox proportional hazards regression model was used to compute and compare the risk of BPH between study participants with and those without hyperthyroidism.Patients with hyperthyroidism exhibited a greater incidence of BPH (18.51% vs 15.53%) than did the controls. Furthermore, the hazard ratio (HR) of the hyperthyroidism group was 1.24 times that of the control group [95% confidence interval (95% CI 1.05-1.46)] signifying that there is a significant 24% increase in the risk of BPH with the presence of hyperthyroidism. This increased risk of BPH with hyperthyroidism, however, failed to remain significant (adjusted HR = 1.11, 95% CI = 0.94-1.3) after adjusting for covariates of age (adjusted HR = 2.72, 95% CI = 2.32-3.2), diabetes (adjusted HR = 1.4, 95% CI = 1.17-1.68), hypertension (adjusted HR = 1.74, 95% CI = 1.49-2.03), hyperlipidemia (adjusted HR = 1.25, 95% CI = 1.03-1.53), neurogenic bladder, cystitis (adjusted HR = 1.23, 95% CI = 0.58-2.59), urethral stricture (adjusted HR = 2.01, 95% CI = 0.28-14.47), urethritis (adjusted HR = 1.52, 95% CI = 0.72-3.21), and urinary tract infection (adjusted HR = 1.77, 95% CI = 1.31-2.39).After adjustment for comorbidities and covariates, hyperthyroidism was not found to be a significant risk factor of BPH in our male study subjects. Further research is warranted to validate our results and elucidate the association of the pathophysiology of these 2 diseases.

Abstract
Fetal cardiac great vessel malformation is attracting increasing attention in the prenatal ultrasonic diagnosis of fetal congenital heart disease. To investigate the clinical diagnostic values of three-vessel-trachea view (3VT view) in the ultrasonic diagnosis of this malformation, the present study analyzed the echocardiographic examination results of 77 fetuses with great vessel malformation, retrospectively analyzed the echocardiographic characteristics in the three-vessel-trachea view, and followed up the enrolled cases. The results suggest that great vessel malformation had characteristic manifestations, such as abnormal arrangement order, inner diameter, blood flow direction and branch. Color Doppler flow imaging found V, O, C, U, Ioo and oVo structures. There were 20 cases of blood vessel position abnormality, 38 cases of abnormal blood vessel diameter, and 19 cases of abnormal number of blood vessels. The detection rate of abnormal blood vessel diameter was 95%, which was the highest; the detection rate of abnormal blood vessel position was 97.4%, and that of abnormal number of blood vessels was 84.2%. It is concluded that the 3VT view can indicate fetal cardiac great vessel malformation. The 3VT view is beneficial to timely prenatal diagnosis, relief of body pain and improvement of quality of birth.

Abstract
Cardiopulmonary bypass (CPB) induces inflammatory responses, and effective endogenous homeostasis is important for preventing systemic inflammation. We assessed whether plasma exosomal microRNAs in patients undergoing cardiac surgery with CPB are involved in the regulation of inflammatory responses. Plasma samples were isolated from CPB patients (n = 21) at 5 specified time points: pre-surgery, pre-CPB and 2 hours (h), 4 h and 24 h after CPB began. Plasma TNF-α expression was increased after CPB began compared to that in the pre-surgery samples. Plasma IL-8 and IL-6 expression peaked at 4 h after CPB began but was downregulated at 24 h. The number of plasma exosomes collected at 2 h (55.1 ± 8.3%), 4 h (63.8 ± 10.1%) and 24 h (83.5 ± 3.72%) after CPB began was significantly increased compared to that in the pre-CPB samples (42.8 ± 0.11%). These exosomes had a predominantly parental cellular origin from RBCs and platelets. Additionally, the plasma exosomal miR-223 levels were significantly increased after CPB began compared to those in the pre-CPB samples. Further, exosomal miR-223 from plasma collected after CPB began downregulated IL-6 and NLRP3 expression in the monocytes. Here, we present the novel findings that increased plasma exosomal miR-223 expression during cardiac surgery with CPB might play homeostatic roles in downregulating inflammatory responses through intercellular communication.

Abstract
RATIONALE Airway stenting is a well-established method that relieves symptoms and maintains airway patency in patients with airway obstruction. Serious complications caused by airway stents such as stent dislocation and airway obstruction during surgery are life-threatening. PATIENT CONCERNS An 80-year-old man was treated with bronchial stent for left bronchus obstruction caused by metastatic esophageal cancer. During tracheostomy surgery, he suffered from acute tracheal obstruction caused by dislocated bronchial stent. DIAGNOSES Esophageal cancer, left bronchus obstruction, respiratory failure, tracheal obstruction. INTERVENTIONS Threading a 5.0-sized endotracheal tube combined with an Eschmann tracheal tube introducer to prop up the collapsed stent. OUTCOMES The bronchial stent was re-expanded and threaded into right main bronchus and ventilation restored. LESSONS Patient with airway stent undergoing surgery with airway involved should be performed under the support of a backup physician and equipment that are capable of handling potentially life-threatening complications of airway stent. If not, in the emergent situation of tracheal obstruction due to tracheal/bronchial stent, protruding through the stent with a suitable, small-sized endotracheal tube with Eschmann tracheal tube introducer may be an alternative skill for saving life weighted with possible complications.

Abstract
Blood-brain barrier (BBB) disruption is thought to facilitate the development of cerebral infarction after a stroke. In a typical stroke model (such as the one used in this study), the early phase of BBB disruption reaches a peak 6 h post-ischemia and largely recovers after 8–24 h, whereas the late phase of BBB disruption begins 48–58 h post-ischemia. Because cerebral infarct develops within 24 h after the onset of ischemia, and several therapeutic agents have been shown to reduce the infarct volume when administered at 6 h post-ischemia, we hypothesized that attenuating BBB disruption at its peak (6 h post-ischemia) can also decrease the infarct volume measured at 24 h. We used a mouse stroke model obtained by combining 120 min of distal middle cerebral arterial occlusion (dMCAo) with ipsilateral common carotid arterial occlusion (CCAo). This model produced the most reliable BBB disruption and cerebral infarction compared to other models characterized by a shorter duration of ischemia or obtained with dMCAO or CCAo alone. The BBB permeability was measured by quantifying Evans blue dye (EBD) extravasation, as this tracer has been shown to be more sensitive for the detection of early-phase BBB disruption compared to other intravascular tracers that are more appropriate for detecting late-phase BBB disruption. We showed that a 1 h-long treatment with isoflurane-anesthesia induced marked hypothermia and attenuated the peak of BBB disruption when administered 6 h after the onset of dMCAo/CCAo-induced ischemia. We also demonstrated that the inhibitory effect of isoflurane was hypothermia-dependent because the same treatment had no effect on ischemic BBB disruption when the mouse body temperature was maintained at 37°C. Importantly, inhibiting the peak of BBB disruption by hypothermia had no effect on the volume of brain infarct 24 h post-ischemia. In conclusion, inhibiting the peak of BBB disruption is not an effective neuroprotective strategy, especially in comparison to the inhibitors of the neuronal death signaling cascade; these, in fact, can attenuate the infarct volume measured at 24 h post-ischemia when administered at 6 h in our same stroke model.

Abstract
Coronary artery disease (CAD) is the most common cause of heart attack and the leading cause of mortality in the world. It is associated with mitochondrial dysfunction and increased level of reactive oxygen species production. According to the Ottawa Heart Genomics Study genome-wide association study, a recent research identified that Q688 spastic paraplegia 7 (SPG7) variant is associated with CAD as it bypasses the regulation of tyrosine phosphorylation of AFG3L2 and enhances the processing and maturation of SPG7 protein. This study aims to identify potential compounds isolated from Traditional Chinese Medicines (TCMs) as potential lead compounds for paraplegin (SPG7) inhibitors. For the crystallographic structure of paraplegin, the disordered disposition of key amino acids in the binding site was predicted using the PONDR-Fit protocol before virtual screening. The TCM compounds saussureamine C and 3-(2-carboxyphenyl)-4(3H)-quinazolinone, have potential binding affinities with stable H-bonds and hydrophobic contacts with key residues of paraplegin. A molecular dynamics simulation was performed to validate the stability of the interactions between each candidate and paraplegin under dynamic conditions. Hence, we propose these compounds as potential candidates as lead drug from the compounds isolated from TCM for further study in drug development process with paraplegin protein for coronary artery disease.

Abstract
Primary thyroid lymphoma (PTL) refers to the malignant tumor of primary lymphoid tissue in the thyroid, accounting for approximately 5% of all thyroid malignancies and less than 3% of all extranodal lymphomas. PTL usually develops in females more than 50 years old. Most of PTL cases are non-Hodgkin's lymphomas. The major pathological subtypes are mucosa-associated lymphoid tissue lymphoma and diffuse large B-cell lymphoma. Treatment options for individual pathological subtypes are also different, so pathological diagnosis is very important. The main treatment options include surgical treatment, radiotherapy, chemotherapy, targeted therapy and combined therapy. The main aims of surgical treatment are to obtain a determined diagnosis and to relieve airway pressure, . The prognosis of PTL is generally excellent.

Abstract
AIMS Postoperative pain is a major problem. Electroacupuncture (EA) has been accepted as a useful and low-risk complementary therapy for post-operative pain. Animal studies indicate that surgical incision activates p38 MAPK in the spinal microglia, which critically contributes to post-incisional nociceptive development. How EA affects incision-induced p38 activation is important but yet to be fully elucidated. METHODS Male adult rats received plantar incision (PI) at the right hind paw followed by 30-min EA of 4-Hz, one of two intensities (3 and 10mA), and at right ST36 (Zusanli) acupoint immediately after PI and for 3 successive days. EA analgesia was evaluated by von Frey fibers and Hargreaves' tests. Spinal p38 activation was examined by immunostaining. In separate groups, SB203580, a p38 inhibitor, was intrathecally injected alone or with EA to test the combining effect on nociception and spinal phospho-p38. KEY FINDINGS EA of 10-mA significantly ameliorated mechanical allodynia, but 3-mA did not. None of them altered thermal hyperalgesia. Repeated EA could not inhibit phospho-p38 in the PI rats, contrarily, EA per se significantly induced phospho-p38 in the normal rats. Intrathecal SB203580 injection dose-dependently prevented PI-induced allodynia. Combination of low-dose SB203580 and 3-mA EA, which were ineffective individually, profoundly reduce post-PI allodynia. SIGNIFICANCE We demonstrated that 10-mA EA exerts a significant inhibition against post-PI mechanical hypersensitivity via a p38-independent pathway. Importantly, co-treatment with low-dose p38 inhibitor and 3-mA EA can counteract spinal phospho-p38 to exert strong analgesic effect. Our finding suggests a novel strategy to improve EA analgesic quality.

Abstract
From September 2012 to March 2013, a total of 63 adult-to-adult living donor liver transplantations were performed at our institution. All the patients were monitored for their coagulation functions using rotation thromboelastometry (ROTEM, Tem Innovations GmbH) during the procedure at the following points: preoperative baseline, 5 minutes, 30 minutes, and 120 minutes, respectively, after reperfusion of the liver graft. A total of 84.13% of cases (n = 53) revealed fibrinolysis after reperfusion of the graft and the condition was reversed after 30 minutes without any need for additional treatment. No significant coagulopathy was observed during this period in all of the cases. The result of the ROTEM finding must correlate with the clinical situation before instituting any management to avoid the risk of thrombosis of the hepatic artery.

Abstract
Background Cancellation of surgery close to scheduled time causes a waste of healthcare resources. The current study analyzes surgery cancellations occurring after the patient has been prepared for the operating room, in order to see whether improvements in the surgery planning process may reduce the number of cancellations. Methods In a retrospective chart review of operating room surgery cancellations during the period from 2006 to 2011, cancellations were divided into the following categories: inadequate NPO; medical; surgical; system; airway; incomplete evaluation. The relative use of these reasons in relation to patient age and surgical department was then evaluated. Results Forty-one percent of cancellations were for other than medical reasons. Among these, 17.7% were due to incomplete evaluation, and 8.2% were due to family issues. Sixty seven percent of cancelled cases eventually received surgery. The relative use of individual reasons for cancellation varied with patient age and surgical department. The difference between cancellations before and after anesthesia was dependent on the causes of cancellation, but not age, sex, ASA status, or follow-up procedures required. Conclusion Almost half of the cancellations were not due to medical reasons, and these cancellations could be reduced by better administrative and surgical planning and better communication with the patient and/or his family.

Abstract
A recent research in cancer research demonstrates that tumor-specific pyruvate kinase M2 (PKM2) plays an important role in chromosome segregation and mitosis progression of tumor cells. To improve the drug development of TCM compounds, we aim to identify potent TCM compounds as lead compounds of PKM2 regulators. PONDR-Fit protocol was utilized to predict the disordered disposition in the binding domain of PKM2 protein before virtual screening as the disordered structure in the protein may cause the side effect and downregulation of the possibility of ligand to bind with target protein. MD simulation was performed to validate the stability of interactions between PKM2 proteins and each ligand after virtual screening. The top TCM compounds, saussureamine C and precatorine, extracted from Lycium chinense Mill. and Abrus precatorius L., respectively, have higher binding affinities with target protein in docking simulation than control. They have stable H-bonds with residues A:Lys311 and some other residues in both chains of PKM2 protein. Hence, we propose the TCM compounds, saussureamine C and precatorine, as potential candidates as lead compounds for further study in drug development process with the PKM2 protein against cancer.

Abstract
Human histone deacetylase 2 (HDAC2) has been identified as being associated with Alzheimer's disease (AD), a neuropathic degenerative disease. In this study, we screen the world's largest Traditional Chinese Medicine (TCM) database for natural compounds that may be useful as lead compounds in the search for inhibitors of HDAC2 function. The technique of molecular docking was employed to select the ten top TCM candidates. We used three prediction models, multiple linear regression (MLR), support vector machine (SVM), and the Bayes network toolbox (BNT), to predict the bioactivity of the TCM candidates. Molecular dynamics simulation provides the protein-ligand interactions of compounds. The bioactivity predictions of pIC50 values suggest that the TCM candidatesm, (-)-Bontl ferulate, monomethylcurcumin, and ningposides C, have a greater effect on HDAC2 inhibition. The structure variation caused by the hydrogen bonds and hydrophobic interactions between protein-ligand interactions indicates that these compounds have an inhibitory effect on the protein.

Abstract
Alzheimer's disease (AD) is a neurodegenerative disease that is a great public health problem worldwide. The cause and mechanism of AD are not well understood. Inhalational anesthetics have been suggested to induce neurotoxicity, leading to memory deficits and the progression of AD. However, recent data have shown that inhalational anesthetics may protect against neurotoxicity and are not associated with an increased risk of AD. We used a Drosophila model to directly investigate the neurologic effects of the inhalational anesthetic sevoflurane on AD. Five- to six-day-old control and AD-transgenic flies were exposed to 2.1% or 3% sevoflurane 4 and 16 times for 1 hour each time. Electroretinograms (ERG), retinal immunohistochemistry, climbing ability, and survival were analyzed after sevoflurane treatment. The data were evaluated using Student's t-test or a one-way ANOVA with a supplementary Fisher's LSD (Least Significant Difference) test. Statistical significance was set at p<0.05. The ΔERG, climbing ability, and survival were lower in AD-transgenic flies. Exposure to 2.1% sevoflurane 4 and 16 times and to 3% sevoflurane 16 times rescued the ΔERG in AD-transgenic flies. Sevoflurane exposure did not attenuate the climbing ability or survival of control and AD-transgenic flies. The inhalational anesthetic sevoflurane might not have exerted neurotoxic effects on control and AD-transgenic flies; in fact, sevoflurane might confer selective neuroprotection on the retinal function of AD-transgenic flies. These results suggest the need for future studies to determine the potential effects of anesthetics on AD-associated neuroprotection or neurotoxicity.

Abstract
The aim of this study was to test a causal model of the predictors of agitation among 405 nursing home residents in Taiwan with varying degrees of cognitive impairment. Chart review and behavioral observations were used to assess residents' physical and psychosocial condition. The final version of the model had a good fit. Cognitive function and depression had direct effects on agitation, and pain and functional ability had indirect effects on agitation via depression. Additionally, cognitive function and pain influenced functional ability directly, which in turn influenced depression and ultimately influenced agitation. The results suggest that effective management of agitation in demented residents requires identifying the needs underlying the behavior rather than directly treating the behavior itself.

Abstract
BACKGROUND Glycogen-synthase kinase 3 (GSK3) is involved in many signaling pathways and is associated with a host of high-profile pathophysiological states. However, its role in morphine tolerance, especially naloxone-precipitated withdrawal syndrome, has not been well investigated. The present study was undertaken to study the role of GSK3 in chronic morphine exposure. METHODS Adult male Sprague-Dawley rats were subjected to intraperitoneal (i.p.) injections of morphine (10 mg/kg) twice daily for 6 consecutive days, and tail-flick tests were conducted to evaluate changes of morphine-induced antinociception. GSK3 inhibitor, SB216763 or SB415286, was i.p. injected prior to morphine to investigate the influences on morphine tolerance. There were four groups receiving morphine plus vehicle (2% dimethyl sulfoxide), morphine plus SB216763 (0.6 mg/kg) or SB415286 (1.0 mg/kg), GSK3 inhibitor alone, or dimethyl sulfoxide: as the control group. On Day 7, naloxone (i.p., 1 mg/kg) was administered and naloxone-precipitated withdrawal behaviors were individually compared between groups. RESULTS Repeated morphine exposure in this study led to progressive shortening of tail-flick latencies and produced six of nine observed naloxone-precipitated withdrawal behaviors. Coadministration with SB216763 or SB415286 significantly prevented antinociceptive tolerance and alleviated parts of withdrawal syndrome. Both inhibitors could similarly reverse withdrawal behaviors including grooming, chewing, and ptosis, but did not affect withdrawal behaviors of penis licking and defecation. CONCLUSION The results demonstrate the importance of GSK3 in reducing chronic morphine-induced tolerance and withdrawal syndrome. Although GSK3 is involved in diverse physiological functions, aiming at GSK3-related pathway could still be a potential tool to improve therapeutic quality in clinical morphine treatment.

Abstract
There are conflicting reports on cancer risk associated with angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs). This retrospective cohort study was conducted to analyze the risk of cancer development in patients who received ACE inhibitors/ARBs as treatment for essential hypertension. Using the Taiwan National Health Insurance Research Database, 297,688 eligible study patients with essential hypertension were identified. According to their antihypertensive prescriptions, the study patients were stratified into an ACE inhibitor group, an ARB group, or a control group. After matching, participants were observed for the occurrence of cancer. In the ACE inhibitor group compared with the control group, the hazard ratio was 0.51 (95% confidence interval, 0.39-0.68). In the ARB group compared with the control group, the hazard ratio was 0.8 (95% confidence interval, 0.65-0.97). Regular use of ACE inhibitors/ARBs was not associated with an increased risk of cancer development and was actually found to decrease overall cancer risk in this study.

Abstract
Atrial fibrillation (AF) is not only the most common arrhythmia in the global population but also the most frequent one encountered in the operating room. For an anesthesiologist, it is crucial to have the ability to maintain hemodynamics and prevent complications of patients who present AF perioperatively. Here we provide a brief review in the novel concept of the classification, pathophysiology, and management of AF to provide a practical approach for physicians coming across this arrhythmia during the perioperative period.

Abstract
OBJECTIVE Amniotic fluid embolism syndrome is a fatal disease in pregnant women. The exact role of platelets and neutrophils in amniotic fluid embolism syndrome is not clear. We examined whether amniotic fluid could affect platelet-neutrophil aggregation and activation and the possible mechanisms. STUDY DESIGN Blood samples from the pregnant women were pretreated ex vivo with their own amniotic fluid. Flow cytometry was used to measure platelet-neutrophil aggregation and activation. Neutrophil-mediated activity of p38 mitogen-activated protein kinase and extracellular signal-regulated protein kinases 1 and 2 was analyzed by Western blotting. RESULTS Amniotic fluid significantly induced platelet-neutrophil aggregation, neutrophil CD11b expression, and reactive oxygen species production. Amniotic fluid induced minimal platelet P-selectin expression. The increase of intracellular calcium level of neutrophils and the activity of p38 mitogen-activated protein kinase were enhanced by amniotic fluid stimulation. CONCLUSION Amniotic fluid was able to induce neutrophil activation and platelet-neutrophil aggregation with minimal effect on platelet activation. These findings may provide a new insight in the understanding of the pathophysiologic condition of amniotic fluid embolism syndrome.

Abstract
Abstract
Intro: The Institute of Medicine advocates survivorship care plans (SCPs) as tools to improve coordination of care by improving survivor knowledge of follow-up recommendations and future risks. No evidence exists to demonstrate that SCPs impact survivor knowledge of diagnosis, treatment, or future/chronic side effects. Furthermore, there is a lack of information on existing surveys and their ability to assess survivor knowledge regarding these issues, without change over time. The purpose of this research is to report on the development of a survey assessing knowledge of diagnosis, treatment, and side effects in BrCa survivors.
Methods: Using existing literature, two oncologists created 24 questions addressing knowledge of diagnosis, treatment, and side effects. Content experts including breast oncology providers (representing multiple subspecialties), Survey Research Shared Service (SRSS) and patient advocates reviewed and revised the questions. Next, potential questions were administered in a group setting to BrCa survivors to evaluate clarity of instructions and survey wording. The Breast Cancer Knowledge (BreaCK) survey was further revised based on survivor feedback.
For pilot testing, BrCa survivors were recruited from clinic to test BreaCK survey content and clarity. Survey 1 was administered in clinic online. SRSS conducted verbal assessments regarding content after Survey 1. Four weeks later, survivors received Survey 2 via email and answered online. Correct answers were abstracted from the medical record.
Results: Nine subjects completed both surveys. Qualitatively, little intra-subject variation was seen between surveys. Subjects did not feel that the survey was burdensome or intrusive. No subject was able to correctly answer all questions. Final survey adjustments were made based on subject feedback and common incorrect answers encountered when grading the surveys. Specifically, subjects had difficulty understanding “endocrine or hormone therapy.” Furthermore, subjects reported guessing in response to some questions – additional answer categories were added, including “I don't know.”
Conclusion: Survivor knowledge did not change significantly between surveys. This suggests survivor knowledge was not impacted by the survey over the four-week interval. The revised BreaCK survey may be a useful tool for assessing survivor knowledge of diagnosis, treatment and side effects. A larger cohort of BrCa survivors is being recruited, starting Summer 2012, and will be evaluated using the survey.

Abstract
Prostate cancer is the most common cause of cancer death in men and is a major health problem worldwide. Methylene tetrahydrofolate reductase (MTHFR) plays an important role in folate metabolism and is also an important source of DNA methylation and DNA synthesis (nucleotide synthesis). To assess the association and interaction of genotypic polymorphisms in MTHFR and lifestyle factors with prostate cancer in Taiwan, we investigated two well-known polymorphic variants of MTHFR, C677T (rs1801133) and A1298C (rs1801131), analyzed the association of specific genotypes with prostate cancer susceptibility, and discussed their joint effects with individual habits on prostate cancer risk. In total, 218 patients with prostate cancer and 436 healthy controls recruited from the China Medical Hospital in central Taiwan were genotyped for these polymorphisms with prostate cancer susceptibility. We found the MTHFR C677T but not the A1298C genotype was differently distributed between the prostate cancer and control groups. The T allele of MTHFR C677T conferred a significantly (p=0.0011) decreased risk of prostate cancer. As for the A1298C polymorphism, there was no difference in distribution between the prostate cancer and control groups. Gene interactions with smoking were significant for MTHFR C677T polymorphism. The MTHFR C677T CT and TT genotypes in association with smoking conferred a decreased risk of 0.501 (95% confidence interval=0.344-0.731) for prostate cancer. Our results provide the first evidence that the C allele of MTHFR C677T may be associated with the development of prostate cancer and may be a novel useful marker for primary prevention and anticancer intervention.

Abstract
Maternal methamphetamine (MA) abuse during pregnancy has been proved to induce various impacts on the development of infant and child. In this study, we examined whether prenatal exposure to MA would affect the development of nociceptive system by measuring the responses to noxious stimulation in the developing rat. Adult female Sprague-Dawley rats received bi-daily subcutaneous injection of methamphetamine (5mg/kg) or isovolumetric normal saline since the day of mating till the day of delivery. Birth profiles of the offspring including birth length, weight, and body temperature were recorded during the first postnatal month. Mechanical withdrawal thresholds were measured by von Frey filaments on postnatal day (PND) 30 and 60, and hyperalgesic behaviors following plantar formalin injection (2%, 50 microl) were evaluated on PND 60. The birth body weight and length of rats born to MA-injected dam rats (MA group) were significantly lower than those of the control rats during the first postnatal month; however, their body temperature was significantly higher than those of the control rats during the first 3 days after birth. The MA group rats had significantly lower tactile withdrawal values in von Frey test and higher pain scores in the late phase of pain in the formalin test than those of the control rats. There is a gender difference of nociceptive hypersensitivity manifested as that the female MA group rats had significantly lower withdrawal thresholds and higher pain scores in response to formalin injection than the male MA group rats. These results suggest that prenatal MA exposure could predispose an alteration in the development of nociceptive neuronal network, which leads to a long-lasting status of hypersensitivity to pain stimulations in the offspring.

Abstract
Peripheral neuropathy is common in people chronically overexposed to arsenic. We studied sodium arsenite (arsenite)-induced cytotoxicity in dorsal root ganglion (DRG) explants. Incubation with arsenite concentration- and time-dependently increased the expression of stress proteins, heat shock protein 70, and heme oxygenase-1 in DRG explants. Furthermore, apoptosis was involved in the arsenite-induced cytotoxicity in the treated DRG. Elevation in cytosolic cytochrome c levels and reduction in procaspase 3 levels suggested an involvement of the mitochondrial pathway in arsenite-induced apoptosis in this preparation. At the same time, increases in the activating transcription factor-4 and C/EBP homologous protein and reduction in procaspase 12 levels indicated activation of the endoplasmic reticulum (ER) pathway in the arsenite-induced cytotoxicity in DRG explants. Salubrinal (30 microM), an ER inhibitor, was found to attenuate arsenite-induced DNA fragmentation and reduction in procaspase 12 in DRG explants. Cytotoxic effects by arsenite, sodium arsenate (arsenate), monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA) were compared, and the potency was as follows: arsenite >>> arsenate>MMA and DMA. Recombinant adenovirus vectors encoding glial-cell-derived neurotrophic factor (AdGDNF) genes allowed a stable delivery of GDNF genes to the infected cells in DRG explants. Applied in this manner, AdGDNF was found to inhibit arsenite-induced DNA fragmentation in DRG explants. Moreover, AdGDNF attenuated the arsenite-induced reduction in procaspases 3 and 12 levels. Taken together, our study demonstrates that arsenite is capable of inducing cytotoxicity in DRG explants. Both ER and mitochondria pathways are involved in the arsenite-induced apoptosis in DRG explants. Glial-cell-derived neurotrophic factor appears to be protective against arsenite-induced peripheral neuropathy.

Abstract
Syndrome of inappropriate secretion of antidiuretic hormone and diabetes insipidus occurring in very short order in the same patient is rare. We report a 9 month-old male infant suffering form holoprosencephaly developed syndrome of inappropriate secretion of antidiuretic hormone followed by diabetes insipidus within a relative short time postoperatively after his third operation. Inability to suppress as well as to stimulate arginine vasopressin secretion and anesthetic and surgical stresses, were thought to be the possible causes of this event.

Abstract
A 26-year-old pregnant woman with a body mass index of 60 was scheduled for cesarean section at 36 weeks' gestation. She was found having affected with gestational diabetes mellitus and hypertension at 17 weeks of pregnancy. The blood glucose level as controlled by subcutaneous injection of insulin was maintained at the level of 110-140 mg/dL. Hypertension was also controlled by methyldopa and hydralazine with the systolic pressure maintaining at 140-180 mmHg during the pregnancy. Abnormal perfusion of umbilical artery without compromise of placental function was found twice by Doppler prenatal examination at gestation of 33 and 34 weeks respectively. The operation was performed under general anesthesia. However, apnea and low Apgar score of the neonate were noted. General anesthesia was thought as the root cause of this event at first. After a series of examination and management, hypoglycemia and uteroplacental perfusion insufficiency were considered as the causes of this morbidity. The neonate's condition was improved in 48 hr after close care.
