Abstract
Thermomagnetic properties, and its effects on Fisher information entropy with Schioberg plus Manning-Rosen potential are studied using NUFA and SUSYQM methods in the presence of the Greene-Aldrich approximation scheme to the centrifugal term. The wave function obtained was used to study Fisher information both in position and momentum spaces for different quantum states by the gamma function and digamma polynomials. The energy equation obtained in a closed form was used to deduce numerical energy spectra, partition function, and other thermomagnetic properties. The results show that with an application of AB and magnetic fields, the numerical energy eigenvalues for different magnetic quantum spins decrease as the quantum state increases and completely removes the degeneracy of the energy spectra. Also, the numerical computation of Fisher information satisfies Fisher information inequality products, indicating that the particles are more localized in the presence of external fields than in their absence, and the trend shows complete localization of quantum mechanical particles in all quantum states. Our potential reduces to Schioberg and Manning-Rosen potentials as special cases. Our potential reduces to Schioberg and Manning-Rosen potentials as special cases. The energy equations obtained from the NUFA and SUSYQM were the same, demonstrating a high level of mathematical precision.

Abstract
Axillary arch is the most common type of axillary muscle fiber variation, with about 10.8% incidence in the Chinese population. Its natural forms are varied and fluid, with different starting points and terminations, and clinicians frequently lack recognition. Under commonly applicated sentinel lymph node biopsy, the axillary arch has been endowed with more clinical significance. The fabric of axillary arch will not only block lymphatic drainage in axilla and unclear anatomical level of axillary dissection, but also compress the axillary neurovascular bundle, causing upper limb venous thrombosis, lymphedema and nerve entrapment. The intumescent axillary arch may also show abnormal axillary bulge. In addition to finding axillary arch during cadaveric study and operation, several of imaging methods availably diagnose axillary arch preoperative, which can create new way for detection of axillary arch and extension of the surgical plan of sentinel lymph node biopsy. Although embryology and comparative anatomy have been used to explain the origin of the axillary arch, most of the ideas are still hypotheses and need further study.

Abstract
Objective: To establish an in vitro organoid model of human salivary gland basal cell adenoma (BCA). Methods: Fresh tumor sample from a 66-year-old female patient diagnosed with salivary gland BCA was collected from the Dpartment of Oral pathology, Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine in October 2021. And the organoid culture was performed in vitro in a culture medium based on solid droplets of matrix gel, and the growth of the organoid was observed by inverted microscopy. After 14 days, the organoid was fixed in 10% neutral formalin and made into paraffin blocks by agar pre-embedding paraffin embedding method, sectioned. HE staining, morphological observation and immunohistochemical staining of p63, Ki-67, cytokeratin14 (CK14), β-catenin, S-100 and calponin were used for organoids identification. Results: The established BCA organoids were lobulated nodular locally under light microscopy, with deposition of eosinophilic glass-like material around the nests of organoid cells, similar to the morphological architectures of the parental BCA. Immunohistochemistry showed that organoids expressed CK14, p63, and β-catenin in various degree, which was consistent with the immunophenotypic characteristics of the parental BCA tumor cells. Conclusions: An in vitro culture system of BCA organoids was preliminarily established which provides a new model for the study of the pathogenesis of salivary gland tumors.

Abstract
Objective: To report the clinical characteristics and treatment courses of pneumatosis cystoides intestinalis(PCI) after lung transplantation(LT). Methods: We included all cases of PCI after LT from March 2017 to June 2021 in China-Japan Friendship Hospital. In addition to our cases, we searched literatures published in Chinese and English languages using China National Knowledge Infrastructure (CNKI), Wanfang Data and PubMed/MEDLINE with the search terms"pneumatosis intestinalis"and"lung transplantation". The clinical characteristics and treatment courses of all cases were summarized and analyzed. Results: Three cases of PCI occurred after LT in this study, with an incidence of 0.804% (3/373). Thirteen related literatures were retrieved, with 51 cases enrolled. The median age of the 54 patients was 55.4 years (22-79 years), with 33 males and 21 females. 64.81% (35/54) of the 54 patients underwent LT for interstitial lung disease and 90.74% (49/54) underwent bilateral LT. Twenty-two cases(40.7%) were asymptomatic when PCI occurred. Thirty-eight cases (38/54,70.37%)had involvement of ascending colon, and 35 cases(35/54,64.81%)had involvement of transverse colon. Forty-three cases(43/54, 79.63%) were treated conservatively. The average interval between transplantation and PCI was 210 (5-2 495) days. Conclusion: PCI is a rare complication after lung transplantation, most often occurring in the colon. Most patients were asymptomatic and could improve by conservative treatments.

Abstract
Objective: To study the risk factors of adverse pregnancy outcomes for induced abortion of cesarean scar pregnancy in midtrimester. Methods: A national multicenter retrospective study was conducted. A total of 154 singletons pregnant women with cesarean scar pregnancy during the second trimester induced abortion by various reasons in 12 tertiary A hospitals were selected, their pregnant outcomes were observed and the risk factors of serious adverse outcomes were analyzed with univariate and multivariate logstic regression; the role of ultrasound and MRI in predicting placenta accreta and severe adverse outcomes was evaluated, the effectiveness of uterine artery embolization (UAE) in preventing hemorrhage in pregnant women with and without placenta accreta was compared. Results: Among 154 subjects, the rate of placenta accreta was 42.2% (65/154), the rate of postpartum hemorrhage≥1 000 ml was 39.0% (60/154), the rate of hysterectomy was 14.9% (23/154), the rate of uterine rupture was 0.6% (1/154). The risk factor of postpartum hemorrhage≥1 000 ml and hysterectomy was placenta accreta (P<0.01). For each increase in the number of parity, the risk of placenta accreta increased 2.385 times (95%CI: 1.046-5.439; P=0.039); and the risk of placenta accreta decreased with increasing ultrasound measurement of scar myometrium thickness (OR=0.033, 95%CI: 0.001-0.762; P=0.033). The amount of postpartum hemorrhage and hysterectomy rate in the group with placenta accreta diagnosed by ultrasound combined with MRI were not significantly different from those in the group with placenta accreta diagnosed by ultrasound only or MRI only (all P>0.05). For pregnant women with placenta accreta, there were no significant difference in the amount of bleeding and hysterectomy rate between the UAE group [median: 1 300 ml; 34% (16/47)] and the non-embolization group (all P>0.05); in pregnant women without placenta accreta, the amount of bleeding in the UAE group was lower than that in the non-embolization group (median: 100 vs 600 ml; P<0.01), but there was no significant difference in hysterectomy rate [2% (1/56) vs 9% (3/33); P>0.05]. Conclusions: (1) Placenta accreta is the only risk factor of postpartum hemorrhage≥1 000 ml with hysterectomy for induced abortion of cesarean scar pregnancy in midtrimester; multi-parity and ultrasound measurement of scar myometrium thickness are risk factors for placenta accreta. (2) The technique of using ultrasound and MRI in predicting placenta accreta of cesarean scar pregnancy needs to be improved. (3) It is necessary to discuss of UAE in preventing postpartum hemorrhage for induced abortion of cesarean scar pregnancy in midtrimester.

Abstract
Objective: To explore the application effect and evaluation of virtual reality technology in oral implant therapy training. Methods: In November 2018, one adult patient (female, 36 years old) with missing right mandibular first molar was treated in the Department of Implantology, School and Hospital of Stomatology, Fujian Medical University. The three-dimensional virtual models of mandible and implant surgery tools were established, and the virtual reality software (Unity 3D 5.5.1) was imported. Combined with the virtual reality head mounted display, a virtual reality training system simulating the dental implant treatment process was independently developed. Ten refresher doctors and 20 graduate students in Department of Implantology, School and Hospital of Stomatology, Fujian Medical University from September 2018 to December 2019 were recruited as the experimental objects (no clinical experience was found). According to the level and seniority of doctors, they were randomly divided into virtual training group and conventional training control group, which made the two groups comparable, with 15 in each group. Subjective scores (including anatomical structure, surgical field of vision, cavity preparation, implant placement and process mastery) were given after the corresponding training in the two groups, and the virtual reality training system was used to test. The mesial and distal direction, buccolingual direction, depth and angle deviation of implants before and after the training were analyzed, and the differences between the two groups were compared. Results: The subjective scores of five dimensions in the virtual training group were significantly higher than those in the conventional training control group (P<0.05). In the virtual training group, the mesial and distal, buccolingual, depth and angle deviation of implants were (0.73±0.33), (0.78±0.41), (0.61±0.32) mm and 6.66°±3.87°. All of them were significantly lower than those in the control group [(0.85±0.32), (1.12±0.38), (0.89±0.24) mm and 9.68°±3.74°] (P<0.05). Conclusions: The self-developed virtual reality system of oral implant has good application effect, good operability and predictability. It can be effectively carried out in implant education and training, and it can strengthen skills of doctors, and is conducive to the practical operation.

Abstract
Objective: To investigate the clinical effect of free fibula flap transplantation in repairing the defect of mandibular osteoradionecrosis (ORN). Methods: A total of 151 mandibular ORN patients undergoing free fibular flap transplantation were selected from August 2005 to September 2020 in the Department of Oral and Maxillofacial Surgery, Sun Yat-sen Memorial Hospital, Sun Yat-sen University. Among them, 109 patients were males and 42 patients were females, aged (54.1±10.1) (ranged 31-85) years old. The clinical data of the patients was collected and the survival rate of the flaps and postoperative function were calculated to evaluate the surgical efficacy. The χ2 test was used for difference analysis. Results: Among the 151 patients, mandibular ORN caused by radiotherapy for nasopharyngeal carcinoma accounted for 79.5% (120/151). The average time for mandibular ORN appeared was 5(6) years after radiotherapy. Facial artery [57.2%(87/152)] and superior thyroid artery (50/152, 32.9%) were the main anastomotic arteries in the recipient area. There was no significant difference in the necrosis rates of the two flaps [10.3%(9/87) and 12.5%(5/50), respectively, P=0.949]. The main anastomotic veins in the recipient area were the external jugular vein [48.4%(135/279)] and the common facial vein [26.5%(74/279)]. Twenty-five cases (16.6%) had one vein anastomosed, and 126 cases (83.44%) had two veins anastomosed. There was no significant difference in the flap necrosis rate between the two conditions [20.0%(5/25) and 7.1%(9/126), respectively, P=0.100]. Ninety-seven cases (64.2%) used the peroneal musculocutaneous-fascia composite flap to repair the maxillofacial soft and hard tissue defects. Thirteen cases (8.6%) underwent the restorations with digital virtual surgery design, of which 5 cases were repaired with dental implants at the same time. After the operations, lower respiratory tract infection occurred in 17 patients (11.3%), and upper respiratory tract obstruction occurred in 3 cases (2.0%). The survival rate of the flap after operation was 90.7% (136/151), and 21 patients (13.9%) had flap vascular crisis. Delayed healing of maxillofacial wounds occurred in 33 cases (21.9%). After 3 to 24 months of follow-ups, 110 patients (76.9%) had no fistula inside/outside the oral cavity, 118 patients (82.5%) had an improvement in opening mouth of increasing (≥0.5 cm) after surgery, 135 patients (94.4%) had pain relief, 97 cases (67.8%) could eat normal diet, semi-liquid or soft food, and 137 cases (95.8%) were satisfied or basically satisfied with the treatment effects. Conclusions: The free fibular flap transplantation is an effective method to repair mandibular ORN defects. Preoperative vascular assessment is helpful for the selection of recipient vessels. Facial artery, superior thyroid artery, external jugular vein and common facial vein can be used as the main recipient vessels. The repair of the peroneal musculocutaneous-fascia composite flap facilitates the closure of internal and external fistulas. Digital technology can help to restore the maxillofacial shape more accurately, improve the patient's occlusal and chewing function and enhance the quality of life of mandibular ORN patients.

Abstract
OBJECTIVE Our study aimed to investigate miR-193a-3p expression and its clinical significance in pituitary adenomas (PAs). Moreover, the correlation between miR-193a-3p expression and the invasiveness of PAs was explored. PATIENTS AND METHODS In this study, the relative expression levels of miR-193a-3p were detected via quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The correlations between miR-193a-3p and tumor size, clinical features, and prolactinomas postoperative prolactin (PRL) levels early remission were further analyzed. RESULTS Compared with non-invasive PAs, there was a lower miR-193a-3p expression in invasive PAs. MiR-193a-3p expression had reverse relevance to tumor size. A higher risk of postoperative residual and recurrence was found in patients with downregulated miR-193a-3p. Prolactinomas patients with postoperative PRL levels early remission were at lower risk to relapse and patients with high-expression miR-193a-3p had a higher early remission rate, suggesting that miR-193a-3p was a significant prognostic factor for prolactinomas. CONCLUSIONS MiR-193a-3p could have potential therapeutic value for invasive pituitary adenomas.

Abstract
OBJECTIVE Glioblastoma (GBM) is a fast-growing type of central nervous system tumor with high invasiveness and recurrence. Circular RNA (circRNA) circ-0001801 (also named as circPCMTD1) was recognized as a novel biomarker in cancers. However, the pathological mechanism of circ-0001801 in GBM is still largely obscured. To the best of our knowledge, it is the first time to reveal the involvement of circ-0001801/miR-628-5p/HMGB3 axis in the progression of GBM cells. PATIENTS AND METHODS Expression of circ-0001801, microRNA (miR)-628-5p and high mobility group box 3 (HMGB3) in GBM tumors and cells was detected by quantitative real time-polymerase chain reaction (qRT-PCR). Stability of circ-0001801 was determined by RNase R. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) was performed to analyze cell viability. Cell migration and invasion were assessed using transwell assay. The interaction between miR-628-5p and circ-0001801 or HMGB3 was confirmed by Dual-Luciferase reporter system. Protein expression of HMGB3, N-cadherin, E-cadherin and Vimentin was detected by Western blot. RESULTS The up-regulation of circ-0001801 and HMGB3 and the down-regulation of miR-628-5p were both observed in GBM tumors and cells compared with the normal ones. Depletion of circ-0001801 reduced GBM cell proliferation, migration, invasion and EMT. In addition, we discovered that circ-0001801 was a sponge of miR-628-5p and HMGB3 was a target of miR-628-5p. Furthermore, miR-628-5p inhibitor abolished circ-0001801 silencing-mediated inhibition of cell progression in GBM. Similarly, HMGB3 restored circ-0001801 silencing-mediated repression on GBM cell progression. We also noticed that circ-0001801 could improve HMGB3 expression by sponging miR-628-5p in GBM. CONCLUSIONS Overexpression of circ-00018 01 accelerates cell proliferation, migration, invasion and EMT in GBM by absorbing miR-628-5p and facilitating HMGB3 expression, representing promising targeted therapy for GBM.

Abstract
The purpose of this study was to assess the outcomes of patients with advanced recurrent nasopharyngeal carcinoma (rNPC) and radiation-induced sarcoma of the head and neck (RISHN) who underwent en bloc resection and reconstruction. Fifty-two patients with advanced rNPC (n=36) and RISHN (n=16) underwent en bloc resection and reconstruction with an extended lower vertical trapezius island myocutaneous flap (TIMF). En bloc resection of the tumour (including craniomaxillofacial resections and neck resections) and major defect restoration was successful in all patients. TIMF survival was 92.3%. Postoperative mild hemiplegia occurred in one patient with rNPC. In total, 20 patients (55.5%) in the rNPC group and seven (43.8%) in the RISHN group recovered with no signs of disease at follow-up. No statistically significant difference in recovery status was observed between the rNPC and RISHN groups. En bloc resection of the tumour, including dissection of the carotid artery, ensured microscopic clearance of the disease; this is a viable treatment option for patients with advanced rNPC or RISHN without distant metastasis. The extended vertical lower TIMF is a large, straightforward, and reliable flap for repairing the resultant major defects in the craniomaxillofacial or neck region.

Abstract
A new dynamic foveated imager has been developed and commissioned on the wide-angle infra-red thermography system in the Experimental Advanced Superconducting Tokamak. This technique improves the local spatial resolution by a factor of 2 while maintaining the wide-angle view to ensure safety operation. Taking advantage of the new foveated imager, heat flux splitting under the application of resonant magnetic perturbation (RMP) coils has been clearly observed. The results indicate that the toroidal asymmetric power load pattern is closely related to the perturbation field induced by the RMP coils.

Abstract
BACKGROUND Multiple studies have uncovered the effects that ingested fat has on human blood levels of testosterone. Yet, few reports have discussed the effect of circulating serum free fatty acids (FFAs). The present study aimed to explore the relationship between serum free fatty acids and blood levels of testosterone. METHODS In total, 5719 adults were pooled from the database of the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2012. Based on multivariable-linear regression models, we employed a total of 30 FFAs to interpret the relationship of FFAs with blood levels of testosterone. Two models with covariate adjustments were designated for further evaluation and analysis. RESULTS Capric acid [β = -0.014, 95% confidence interval (CI) = -0.023, -0.004, P = 0.005], myristic acid (β = -0.001, 95% CI = -0.001, 0.000, P ≤ 0.001), pentadecanoic acid (β = -0.013, 95% CI = -0.018, -0.008, P ≤ 0.001), margaric acid (β = -0.011, 95% CI = -0.017, -0.005, P ≤ 0.001) and alpha-linolenic acid (β = -0.001, 95% CI = -0.002, 0.000, P = 0.004) in the fully adjusted model were significantly negatively correlated with the testosterone level inh obese men. In the fully adjusted model for the female analysis, myristic acid, pentadecanoic acid, palmitic acid, margaric acid, stearic acid, myristoleic acid, oleic acid, nervonic acid and alpha-linolenic acid were found significantly associated with the testosterone level. CONCLUSIONS Our findings indicate a significant negative correlation between serum FFAs and blood levels of testosterone. Furthermore, we reveal the essentiality of serum FFAs and their potential effects on the reduction of testosterone levels.

Abstract
Objective: To compare the clinical efficacy of different doses of rabbit antithymocyte globulin (rATG) in haplo-HSCT in the treatment of hematologic malignancies. Methods: Malignant hematological patients treated at our hospital from March 2013 to December 2018 were retrospectively analyzed. These patients were divided into three groups as per three doses of ATG (6 mg/kg, 7.5 mg/kg, and 9 mg/kg) in the conditioning regimens. The transplant outcomes were compared in terms of the occurrence of acute graft versus host disease (GVHD) , infection, and survival. Results: ①Total 288 patients were enrolled in the study, including 182 men and 106 women, with a median age of 18 (6-62) years. Total 110 patients were diagnosed with acute lymphoblastic leukemia (ALL) , 128 with acute myelogenous leukemia (AML) , 8 with chronic myeloid leukemia (CML) , 28 with myelodysplastic syndrome (MDS) , and 14 with mixed cell leukemia (MAL) . There were 159 patients in the ATG-6 group, 72 in the ATG-7.5 group, and 57 in the ATG-9 group. The median follow-up time of post transplantation was 14 (0.2-74) months. ②The incidence of neutrophil engraftment (96.9% , 97.2% , and 96.5% , respectively) and platelet engraftment (92.5% , 87.5% , and 86% , respectively) did not significantly differ among the ATG-6, ATG-7.5, and ATG-9 groups (P=0.972, P=0.276) . The incidence of grades 2-4 acute GVHD was 14.5% , 11.1% , and 8.8% in the three groups, respectively (P=0.493) , chronic GVHD incidence in the three group was 8.8% , 14.3% and 12.0% , respectively (P=0.493) . The infection rates of CMV and EBV in the ATG-9 group (77.2% and 12.5% ) were significantly higher than those in the ATG-6 (43.3% and 3.5% ) , and ATG -7.5 group (44.4% and 1.5% ) (P<0.001 and P=0.033, respectively) . ③Among the three groups, there were no significant difference in the 3-year overall survival [68.5% (95% CI 60.3% -77.9% ) , 60.1% (95% CI 48.3% -74.8% ) , 64.7% (95% CI 51.9% -80.7% ) ], cumulative incidences of relapse [34.6% (95% CI 34.3% -35.1% ) , 38.0% (95% CI 37.3% -38.7% ) , 20.6% (95% CI 20.0% -21.3% ) ], disease-free survival [53.3% (95% CI 44.9% -63.4% ) , 51.9% (95% CI 41% -65.8% ) , 63.9% (95% CI 51.9% -78.7% ) ] and non-relapse mortality [24.2% (95% CI 23.8% -24.5% ) , 26.0% (95% CI 25.4% -26.6% ) , 23.6% (95% CI 26.3% -28.2% ) ] (P=0.648, P=0.165, and P=0.486 and P=0.955) . Conclusion: Low dose (6 mg/kg) of rATG may increase the risk of grade Ⅱ-Ⅳ aGVHD, and a high dose (9 mg/kg) of ATG could significantly increase the risk of CMV and EBV infection. Median dose (7.5 mg/kg) of ATG is expected to reduce the incidence of moderate to severe aGVHD and viral infections without increasing the mortality.

Abstract
Objective: To understand the clinical features and outcomes of chronic liver diseases overlapping with CMV infection. Methods: Clinical characteristics, treatment and outcome of patients of chronic liver diseases overlapping with CMV infection were analyzed retrospectively. T-test was used for measurement data and χ (2) test was used for count data. All measurement data were expressed by (x ± s). P > 0.05 was not determined as significant. P < 0.05 was regarded as statistically significant. Results: Chronic liver diseases overlapping with CMV infections had similar clinical features. Etiopathogenic treatment + symptomatic supportive treatment + CMV overlapping infection treatment (including antiviral therapy, corticosteroids consideration, clearing heat and traditional Chinese choleretic medicine, etc) were the primary principles of therapy. The incidence of cytomegalovirus infection accounted for 4.125% during the corresponding hospitalization period. Cytomegalovirus infection had relatively caused liver function damage in patients with milder clinical symptoms and signs. Biochemical indicators before and after treatment showed that there was no significant difference in total bilirubin (TBil) before (262.93 ± 178.944) μmol/L and after one week of treatment (245.08 ± 179.332) μmol/L (P > 0.05). However, when TBIL was compared with three (156.58 ± 147.461) μmol/L and four weeks (103.39 ± 102.218) μmol/L) of treatment, the decrease was significant (P < 0.05, P < 0.01). Alanine aminotransferase (ALT) after one week (293.57 ± 467.438) U/L (P < 0.01) of treatment was significantly lower than before treatment (782.34 ± 828.801) U/L. Gamma-glutamyl transferase (GGT) after treatment (202.52 ± 155.174)U/L was significantly lower than before treatment(280.69 ± 205.619)U/L). Total bile acid (TBA) was increased after treatment (198.04 ± 155.174)μmol/L, when compared with that of before treatment (62.93 ± 178.944)μmol/L. Biochemical indicators of liver diseases had shown typical features of cholestasis, and the slow and reduced flow of bile acid was tracked and observed. Compared with the advanced group (182.45 ± 214.169) umol/L, the total bilirubin in inflammation group (50.36 ± 26.282) umol/L was decreased (P < 0.05). Moreover, advanced group (122.18 ± 106.780) umol/L (P < 0.05) had elevated total bile acid normalization rate than that of bile acid group (54.82 ± 56.123) umol/L, and the inflammatory phase had significantly better outcome than those with advanced-stage. Conclusion: Chronic liver diseases overlapping with cytomegalovirus infection has a good therapeutic outcome in the inflammatory phase, but in the advanced-stage; the therapeutic efficacy and outcome is poor and perilous.

Abstract
BACKGROUND Diabetes mellitus (DM) is a well-known risk factor for cognitive dysfunction in aged populations. However, there are inconsistent reports about impaired fasting glucose or prediabetes as an independent risk factor for cognitive function. Glutamic acid decarboxylase 65 (GAD65) is the key enzyme responsible for γ-aminobutyric acid synthesis in the central nervous system. Antibodies against GAD65 (GAD65Abs) are not only detected in approximately 80% of early-onset type 1 DM, but also linked to several neurological disorders. AIM This study aims to investigate the association between GAD65Ab titer levels and cognitive performance. In addition, we assessed the effect of GAD65Ab on cognitive function in adults with normal fasting glucose, prediabetes and DM. METHODS A total of 328 subjects aged 49.10 ± 5.72 years were enrolled from the Third Health and Nutrition Examination Survey dataset. Cognitive performance was assessed by three computerized neurobehavioral tests, including the serial digit learning test, simple reaction time test (SRTT) and symbol-digit substitution test (SDST). RESULTS Subjects with higher GAD65Ab titers had significantly poorer cognitive function in the SRTT and SDST (P < 0.05). Additionally, GAD65Ab was associated with cognitive decline in non-diabetic adults after adjusting for a number of relevant variables (P < 0.05 in both SRTT and SDST). CONCLUSIONS These results indicate that GAD65Ab may be a potential marker for cognitive impairment in non-diabetic adults.

Abstract
INTRODUCTION The prevalence of frailty defined by FRAIL-NH varies among different studies in nursing homes, ranging from 19.0% to 75.6%. This study investigated the prevalence of frailty in a nursing home in Taiwan using different diagnostic criteria for frailty. METHODS The 7-item FRAIL-NH scale was used for assessing frailty. There are 7 components: fatigue, resistance, mobility, incontinence or disease, weight loss, eating style and assistance with dressing. Each item is worth 0, 1, or 2 points for a total score of 14 points. We sorted and summarized the patients, according to the number of variables, into the not frail, frail, and most frail groups. Descriptive analysis was applied to understand the basic attributes of the elderly with different degrees of frailty, the influencing factors of frailty, and the occurrence of frailty. RESULTS Our final sample included 34 residents. They were aged between 56 and 100 years (mean age 83.91 ± 10.84), and 18 (52.94%) were female. The frail group revealed a higher prevalence of males than of females. The marital status composition of participants was as follows: 2 (5.88%) unmarried, 24 (70.59%) married, and 8 (23.53%) widowed. The mean FRAIL-NH score was 5.79±3.72. CONCLUSIONS A significant prevalence of frailty defined by FRAIL-NH was observed in a nursing home in Taiwan. Our findings indicate that frailty is an important issue in nursing homes. Further prospective cohort studies using FRAIL-NH evaluation are warranted.

Abstract
BACKGROUND Angiogenesis is an indispensable step in the growth and invasiveness of breast cancers involving a series of exquisite molecular steps. Pro-angiogenic factors, including vascular endothelial growth factor (VEGF), have been recognized as pivotal therapeutic targets in the treatment of breast cancer. More recently, a highly conserved transcription factor Twist has been reported to be involved in tumor angiogenesis and metastasis. METHODS The expression of VEGF-C and Twist was immunohistochemically determined in tissue samples of primary tumors from 408 patients undergoing curative surgical resection for breast cancer. The correlations of VEGF-C and Twist expressions with clinicopathologic parameters as well as survival outcomes were evaluated. RESULTS Of the 408 patients evaluated, approximately 70% had high expression of VEGF-C which was significantly associated with advanced tumor stages (P = 0.019). Similarly, VEGF-C expression was associated with the proliferation index Ki67, N3 lymph node metastasis, and D2-40-positive lymphatic vessel invasion (LVI) in a univariate analysis. Furthermore, patients with high expressions of VEGF-C and Twist (V + T+) had significantly increased lymph node metastasis, higher clinical stage, and worse disease-free survival, DFS (P = 0.001) and overall survival, OS (P = 0.011). CONCLUSIONS Our results suggested that co-expression of VEGF-C and Twist was associated with larger tumor size, higher numbers of lymph node involvement, D2-40-positive LVI, higher risk of distant metastasis, and worse DFS or OS in breast cancer patients.

Abstract
OBJECTIVE To analyze the expression profile of serum cytokines in patients with systemic sclerosis (SSc) and explore its possible regulatory mechanisms. METHODS Serum and DNA of peripheral blood mononuclear cells were collected from 30 SSc patients and 80 normal controls (NCs). According to the presence or absence of interstitial lung disease (ILD) in SSc, the patients were divided into SSc with ILD group and SSc without ILD group. According to the degree of skin involvement, the patients were divided into diffuse systemic scleroderma (dcSSc) group and limited systemic scleroderma (lcSSc) group. According to the presence of anti-topoisomerase-1 antibody (anti-Scl-70 antibody) in the serum of patients with SSc, they were divided into SSc Scl-70 (+) group and SSc Scl-70 (-) group. 27 cytokines in serum were detected by Luminex MAGPIX detection system and Bio-Plex Pro Human Cytokine 27-plex Assay kit: interleukin-1β (IL-1β), interleukin-1 receptor antagonist (IL-1ra), IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12P70, IL-13, IL-15, IL-17, basic fiber growth factor (BASIC FGF), eotaxin, granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor (GM-CSF), interferon-γ (IFN-γ), interferon-gamma induced protein 10(IP-10), monocyte chemotactic protein 1(MCP-1), macrophage inflammatory protein-1α (MIP-1α), macrophage inflammatory protein 1β(MIP-1β), platelet-derived growth factor BB (PDGF-BB), regulated on activation in normal T-cell expressed and secreted (RANTES), tumor necrosis factor-α (TNF-α), and vascular endothelial growth factor(VEGF). Methylation sites were detected by Illumina 450K methylation chip. RESULTS Compared with NCs group, the expression of 12 cytokines (BASIC FGF, eotaxin, G-CSF, GM-CSF, IFN-γ, IL-1β, IL-1ra, IL-6, IP-10, MCP-1, TNF-α and RANTES) in the SSc group significantly increased (P<0.05), IL-5 was decreased expression in the SSc group (P<0.05), there was no significant difference in the expressions of the other 14 cytokines. Compared with lcSSc group, 9 cytokines (eotaxin, IL-5, MCP-1, IL-2, RANTES, IL17A, IL-8, MIP-1β and PDGF-BB) increased in dcSSc group, but there was no significant difference. Compared with SSc without ILD group, IL-15 increased in SSC with ILD group [18.2 (172.97) ng/L vs. 2.03(0.05) ng/L, P<0.05]. Compared with SSc Scl-70 (-) group, the expression of IP-10 decreased in SSc Scl-70 (+) group [1 030 (2 196.6) ng/L vs. 1 878 (2 964) ng/L, P<0.05]. The correlation analysis of serum cytokines with erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) showed that IL-6 was positively correlated with ESR (r =0.04, P= 0.017), MCP-1 (r=0.49, P=0.043) and MIP-1β (r=0.41, P=0.007) positively correlated with CRP. By analyzing the changes of methylation sites of cytokines, it was found that cg17744604 in IL-10 TSS1500 region, cg06111286 in IL-12P70 TSS200 region, cg07935264 in IL-1β TSS200 region, cg01467417 in IL-1ra TSS1500 region, cg03989987 in IL-1ra 5'UTR region and cg21099624 in VEGF TSS200 region were all hypomethylated. CONCLUSION There were different cytokines expression profiles in the serum of SSc patients, and the altered cytokines were correlected with the degree of skin damage and pulmonary fibrosis. Many cytokines were regulated by methylation.

Abstract
BACKGROUND Chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII) may be an oncogenic gene in renal cell carcinoma (RCC). However, the direct association between COUP-TFII expression and patient survival has not been investigated in patients with RCC, and the molecular oncogenesis of COUP-TFII in RCC remains unclear. METHODS The mRNA expression levels of COUP-TFII in the tumors of 283 patients with RCC were determined by RT-qPCR. The remaining 266 patients were categorized into low- and high-expression groups according to the cut off value generated by receiver operating curve (ROC) analysis. The function of COUP-TFII in RCC cells was tested by knockdown experiments in vitro. RESULTS In the present study, it was revealed that the mRNA expression levels of COUP-TFII were significantly higher in tumors compared with those in adjacent non-cancerous tissues, and that the overexpression of COUP-TFII was strongly associated with poor patient survival. It was further demonstrated that knockdown of COUP-TFII suppressed proliferation, and induced apoptosis and cell cycle arrest in RCC cells in vitro. This also resulted in the activation of the mitochondria-mediated apoptosis pathway, impaired migration and invasion of RCC cells through epithelial-mesenchymal transition in vitro, and suppressed tumor growth in vivo. In addition, it was revealed that the induction of cell migration and invasion by COUP-TFII was mediated, at least in part, by integrin subunit β1. CONCLUSIONS In summary, the present study indicated that COUP-TFII is an oncogenic gene in RCC, and a potential therapeutic target for the treatment of the disease.

Abstract
OBJECTIVE Detecting a single serum marker, such as Golgi protein 73 (GP73) or alpha-fetoprotein (AFP), may not meet the requirements for the early diagnosis of hepatocellular carcinoma (HCC) due to low sensitivity and specificity. Therefore, this study aimed to develop a simultaneous multiplex assay of GP73 and AFP. PATIENTS AND METHODS Anti-human GP73- and AFP-coupled microsphere beads and biotin-labeled detectable antibodies were prepared to develop a multiplex assay of GP73 and AFP using the Luminex xMAP technology. The assay was evaluated for cross-reactivity, standard curve, sensitivity, range of detection, and precision. Additionally, the assay was used to determine the levels of serum GP73 and AFP in healthy controls and patients with chronic hepatitis, liver cirrhosis, and HCC. RESULTS The multiplex assay was successfully developed to simultaneously detect GP73 and AFP without cross-reactivity. The sensitivity for GP73 detection was 0.215 ng/mL and that for AFP detection was 0.666 ng/mL. The ranges of GP73 and AFP detection were 0.98-861.08 ng/mL and 2.01-1848.73 ng/mL, respectively. The intra- and inter-assay coefficients of variation (CVs) were <10%, indicating good precision, with recovery rates of 75-125%. The levels of serum GP73 in healthy controls, chronic hepatitis patients, liver cirrhosis patients, and HCC patients were 61.64 ± 30.60 ng/mL, 208.4 ± 99.42 ng/mL, 183.7 ± 82.78 ng/mL, and 214.1 ± 160.5 ng/mL, respectively. The levels of serum AFP in healthy controls, chronic hepatitis patients, liver cirrhosis patients, and HCC patients were 24.87 ± 14.52 ng/mL, 134.4 ± 216.5 ng/mL, 66.45 ± 133.4 ng/mL, and 891.4 ± 1278 ng/mL, respectively. The receiver operating characteristic (ROC) results showed that the area under the curves (AUC) for the combination of GP73 and AFP was 0.972, which was larger than the AUC for each marker. The sensitivity and specificity of the combined detection of GP73 and AFP for the diagnosis of HCC were 90.91% and 98.86%, respectively. The multiplex assay demonstrated a good correlation with enzyme-linked immunosorbent assay (ELISA), with correlation coefficients of 0.818 and 0.982 for GP73 (p<0.001) and AFP (p<0.001), respectively. CONCLUSIONS A multiplex assay for the simultaneous detection of GP73 and AFP with high sensitivity and accuracy was developed for the diagnosis of HCC. This assay may provide a reliable reference for the early diagnosis of HCC.

Abstract
Objective: To investigate the association between the time of neutrophils to the lowest and prognosis of patients with esophageal squamous cell carcinoma (ESCC) treated with non-operative therapy. Methods: The clinical data of 325 non-operative treated ESCC patients were collected in this study. The X-title software was applied to establish optimal threshold of neutrophil reduction to the lowest value. According to the optimal threshold, the patients were divided into early group (115 cases) and late group (210 cases). The clinical features and survival time of the two groups were compared, and the factors of prognosis were analyzed by Cox regression model with univariate and multivariate analysis. Results: The X-title software demonstrated the optimal cutoff values for the time of neutrophils to the lowest was 39 days. The median overall survival time was 21.0 months in the early group which was significantly higher than that in the late group (16.0 months). Multivariate Cox regression analysis showed that the treatment methods and the time of neutrophils to the lowest were independent factors for overall survival of patients with ESCC treated by non-surgical therapy. Compared with radiotherapy alone, concurrent chemoradiation could benefit the survival (HR=0.64, P=0.026). The prognosis of patients in the late group of neutrophils to the lowest (HR=1.38, P=0.038) was poor compared with the early group. Furthermore, stratified by treatment methods, the overall survival of two groups showed statistically significant difference only in patients received concurrent chemoradiation. The mortality risk in the late group was higher than that in the early group (HR=3.53, P=0.010). Conclusion: The time of neutrophils to the lowest is an independent prognosis factor for non-operative treated ESCC patients. The prognosis of patients in the early group is better than that in the late group.

Abstract
Objective: To investigate right ventricular function in patients with pneumoconiosis, and to provide a basis for quantitative diagnosis and treatment of pneumoconiosis in clinical practice. Methods: A total of 43 patients with pneumoconiosis who were hospitalized consecutively in Shijiazhuang Prevention and Treatment Center for Occupational Diseases from May 2015 to May 2016 were enrolled, and according to the stage of pneumoconiosis, they were divided into stage I group with 16 patients, stage II group with 14 patients, and stage III group with 13 patients. A total of 16 healthy subjects were enrolled as control group. Echocardiography was performed and the relevant parameters were recorded, i.e., right ventricular transverse diameter (RVTD), tricuspid annular plane systolic excursion (TAPSE), and right ventricular myocardial performance index(Tei index). Results: There were significant differences in Tei index and TAPSE between all groups (P <0.05) except between the stage I group and the control group in terms of Tei index (P>0.05) and between the stage I group and the stage II group in terms of TAPSE (P>0.05). Right ventricular Tei index was negatively correlated with TAPSE (r=-0.547,P<0.05). Conclusion: A combination of right ventricular Tei index and TAPSE can be used for early quantitative evaluation of right ventricular function in patients with pneumoconiosis.

Abstract
Objective: To investigate the therapeutic effect and mechanism of sodium tanshinone IIA sulfate (STS) on paraquat (PQ)-induced myocardial injuries in a rat model. Methods: Healthy adult Sprague Dawley rats were randomly divided into normal control, PQ, and PQ + STS groups. PQ group was given a single intragastric administration of PQ (80 mg/kg). PQ + STS group was intraperitoneally injected with STS (1 ml/kg) at 30 min following PQ exposure. Rats in control and PQ groups were injected with equal amount of saline. After 12, 24, 48, and 72 h, rats were killed, and the apoptosis of myocardial cells was detected. Myocardial expression of Bax and Bcl-2 was measured. The activity of the nuclear erythroid 2-related factor 2 (Nrf2) pathway was assessed by Western blot. Results: The apoptotic cells in PQ group were significantly increased in a time-dependent manner compared with the control group ( p < 0.01). The rats in PQ group exhibited significantly lower Bcl-2 expression, but notably higher Bax expression at 12, 24, 48, and 72 h after PQ exposure ( p < 0.05 or 0.01). STS intervention markedly reduced the proportion of apoptotic myocardial cells, increased Bcl-2 expression, and decreased Bax expression at 24, 48, and 72 h after treatment ( p < 0.05 or 0.01). The expression of phosphorylated Nrf2 and heme oxygenase 1 in PQ + STS group was significantly increased compared with PQ and control groups ( p < 0.05 or 0.01). Conclusion: STS effectively inhibits PQ-induced myocardial cell apoptosis in rats via modulating the Nrf2 pathway, suggesting its potential as a promising therapeutic agent for PQ-induced myocardium damage.

Abstract
OBJECTIVE To study the alteration of CD8+ memory T cell subsets under different immune statuses during the spontaneous clearance of hepatitis B virus (HBV) in Chinese patients with chronic HBV infection. PATIENTS AND METHODS We analyzed Chinese patients with chronic HBV infection including 10 patients with Hepatitis B surface Antigen (HBsAg) spontaneous seroconversion, 25 patients with Hepatitis B virus e Antigen (HBeAg) spontaneous seroconversion, 25 patients with chronic hepatitis B (CHB), and 25 chronic HBV carriers. The CD8+ T cells in peripheral blood were isolated, and flow cytometry was used to determine the percent change of CD8+ T memory cell subsets. ELISA was used to measure the levels of Interferon-γ (IFN-γ) secretion from CD8+ T cells. RESULTS (1) The percentage of CD8+ TN cells in peripheral blood was lower in the HBsAg seroconversion group than in the HBeAg seroconversion group (p<0.01), and higher in the CHB group and chronic HBV carrier group (p<0.01, 0.01); (2) The percentage of CD8+ TEM-2 memory T cells in peripheral blood was higher in the HBsAg seroconversion group than the HBeAg seroconversion group (p<0.05), CHB group, and chronic HBV carrier group (p<0.01, 0.01); (3) The percentage of CD8+ TEM-1 and CD8+ TCM cells in peripheral blood was higher in the CHB group and HBV carrier group than the HBsAg seroconversion group and HBeAg group, but there were no significant differences between groups (p>0.05); (4) IFN-γ production from CD8+ T cells in peripheral blood was higher in the HBsAg seroconversion group than the HBeAg seroconversion group (p<0.05), CHB group, and chronic HBV carrier group (p<0.05, 0.01). CONCLUSIONS The consistent increase of CD8+ TEM-2 cell subsets may be an important cause of spontaneous clearance of HBV. The disorder of CD8+ memory T cell differentiation may be an important mechanism of chronic HBV infection.

Abstract
Burkitt lymphoma (BL) is a highly malignant non-Hodgkin's lymphoma that is closely
related to the abnormal expression of genes. Familial acute myelogenous leukemia
related factor (FAMLF; GenBank accession No. EF413001.1) is a novel
gene that was cloned by our research group, and miR-181b is located in the intron of
the FAMLF gene. To verify the role of miR-181b and
FAMLF in BL, RNAhybrid software was used to predict target site
of miR-181b on FAMLF and real-time quantitative PCR (RQ-PCR) was
used to detect expression of miR-181b and FAMLF in BL patients, Raji
cells and unaffected individuals. miR-181b was then transfected into Raji and CA46
cell lines and FAMLF expression was examined by RQ-PCR and western
blotting. Further, Raji cells viability and proliferation were detected by MTT and
clone formation, and Raji cell cycle and apoptosis were detected by flow cytometry.
The results showed that miR-181b can bind to bases 21–42 of the
FAMLF 5′ untranslated region (UTR), FAMLF was
highly expressed and miR-181b was lowly expressed in BL patients compared with
unaffected individuals. FAMLF expression was significantly and
inversely correlated to miR-181b expression, and miR-181b negatively regulated
FAMLF at posttranscriptional and translational levels. A
dual-luciferase reporter gene assay identified that the 5′ UTR of
FAMLF mRNA contained putative binding sites for miR-181b.
Down-regulation of FAMLF by miR-181b arrested cell cycle, inhibited
cell viability and proliferation in a BL cell line model. Our findings explain a new
mechanism of BL pathogenesis and may also have implications in the therapy of
FAMLF-overexpressing BL.

Abstract
We evaluated the aesthetic outcomes in 11 young patients (mean (range) age 21.7 (16-28) years) who had endoscopically assisted extracapsular dissection of benign pleomorphic adenomas of the parotid gland through a postauricular sulcus approach. The tumours varied in size from 1.5×1.0cm to 2.5×2.0cm, and all were removed completely without rupture. The cosmetic result was excellent in 10 patients and good in one. Patients were followed up for eight to 40 months, and there was no recurrence. The technique is simple and feasible, and it achieves excellent aesthetic results in young patients.

Abstract
Anterior cruciate ligament (ACL) reconstruction (ACLR) surgeries successfully restore anterior tibial translation but not tibial rotation. This study aimed to explore landing strategies focusing on the control of tibial rotation at landing when the ACL is most vulnerable. Three groups of male subjects (50 ACLRs, 26 basketball players, and 31 controls) participated in one-leg forward hop tests for determining the tibial rotatory landing strategies adopted during the initial landing phase. The differences in knee kinematics and muscle activities between internal and external tibial rotatory (ITR, ETR) landing strategies were examined. A higher proportion of basketball players (34.6%) were found to adopt ITR strategies (controls: 6.5%), exhibiting significantly greater hopping distance and knee strength. After adjusting for hopping distance, subjects adopting ITR strategies were found to hop faster with straighter knees at foot contact and with greater ITR and less knee adduction angular displacement during the initial landing phase. However, significantly greater angular displacement in knee flexion, greater medial hamstring activities, and greater co-contraction index of hamstrings and medial knee muscles were also found during initial landing. Our results support the importance of the recruitments of medial hamstrings or the local co-contraction in assisting the rotatory control of the knee during initial landing for avoiding ACL injuries.

Abstract
INTRODUCTION A variety of inflammatory disorders influence the serum white blood cell (WBC) count. Elevated systemic inflammatory insult may contribute to impaired lung function, such as obstructive or restrictive lung disease. The aim of our study is to investigate the correlation between WBC count and pulmonary function. MATERIAL AND METHODS Eligible participants aged ≥18 years (n=16 312) were enrolled from the United States National Health and Nutrition Examination Survey III, 1988-1994. Pertinent information including pulmonary function test, demographics, WBC count, glucose, C-reactive protein and a personal health questionnaire were obtained for subjects without known pulmonary diseases. White blood cell counts were classified into quartiles over the normal range. Multiple hierarchical regression models and trends testing were used to assess the correlation between WBC counts and pulmonary function tests. RESULTS In the unadjusted mode of quartile-based analysis, the beta coefficients interpreted as the differences in FEV1% predicted upon comparing subjects in the upper three quartiles of WBC count to those in the lowest quartile were -0.007, -0.022 and -0.041 (P<0.001). After adjusting for multiple pertinent covariates, inverse association between quartiles of WBC count and FEV1% predicted remained essentially unchanged. The negative trends between FEV1% predicted and WBC count quartiles in the stratified comparison with extended-model approach were statistically significant (P for trends<0.001) in quartile-based multiple linear regression. CONCLUSIONS Elevated WBC count is independently associated with declined pulmonary function. It may be a simple, accessible and inexpensive indicator of changes in pulmonary function.

Abstract
The current augmented-view device for glaucoma patients are limited by the low angle minification (less than 3X), image overlapping and pupil mismatching. We present a novel ultra-thin near-eye augmented-view device (UNAD) with a proper minification angle of 4X to avoid scanning eye movements. The device is realized by one symmetrical ultra-thin off-axis eight-mirror reversed telescopic optical system (field-of-view (FOV): x:-34°~3°; y: -5°~-20°, 5°~20°) and one central un-minified optical system (FOV: -5°~5°), and hence, the system can achieve a FOV (x:-34°~3°; y: -20°~20°) without overlapping images. Furthermore, the device fully accounts for pupil matching with the entrance pupil of the human eye. Finally, the simulation results in CODE V and LightTools verify that our proposed system is feasible and has potential practical value for glaucoma patients.

Abstract
The familial acute myeloid leukemia related factor gene (FAMLF) was previously identified from a familial AML subtractive cDNA library and shown to undergo alternative splicing. This study used real-time quantitative PCR to investigate the expression of the FAMLF alternative-splicing transcript consensus sequence (FAMLF-CS) in peripheral blood mononuclear cells (PBMCs) from 119 patients with de novo acute leukemia (AL) and 104 healthy controls, as well as in CD34+ cells from 12 AL patients and 10 healthy donors. A 429-bp fragment from a novel splicing variant of FAMLF was obtained, and a 363-bp consensus sequence was targeted to quantify total FAMLF expression. Kruskal-Wallis, Nemenyi, Spearman's correlation, and Mann-Whitney U-tests were used to analyze the data. FAMLF-CS expression in PBMCs from AL patients and CD34+ cells from AL patients and controls was significantly higher than in control PBMCs (P < 0.0001). Moreover, FAMLF-CS expression in PBMCs from the AML group was positively correlated with red blood cell count (rs =0.317, P=0.006), hemoglobin levels (rs = 0.210, P = 0.049), and percentage of peripheral blood blasts (rs = 0.256, P = 0.027), but inversely correlated with hemoglobin levels in the control group (rs = -0.391, P < 0.0001). AML patients with high CD34+ expression showed significantly higher FAMLF-CS expression than those with low CD34+ expression (P = 0.041). Our results showed that FAMLF is highly expressed in both normal and malignant immature hematopoietic cells, but that expression is lower in normal mature PBMCs.

Abstract
OBJECTIVE Volatile essential oils of mint species are used for cosmetics and in skin care products. In this study, we evaluated the main chemical components of the lime mint and the anti-melanogenic properties of its main components. METHODS The essential oil was analysed by gas chromatography-mass spectrometry (GC/MS). The anti-melanogenic effects of mint essential oil and β-caryophyllene were investigated in B16F10 murine melanoma cells. RESULTS The main components of lime mint essential oil were found to be D-limonene (41.10%), D-carvone (8.58%), δ-selinene (6.73%) and β-caryophyllene (6.24%). The lime mint essential oil reduced melanin production in a dose-dependent manner in murine B16F10 cells. β-Caryophyllene, one of the main compounds in lime mint essential oil, could reduce melanogenesis by down-regulating the expression of MITF, TRP-1, TRP-2 and tyrosinase, resulting in a decrease in melanin content decrease. CONCLUSION These results reveal that lime mint essential oil and β-caryophyllene are considered to be valuable as potential skin-whitening agents.

Abstract
Non-syndromic cleft of the lip and/or palate (NSCLP) is a very common birth defect; the poliovirus receptor-like 1 gene (PVRL1) has been identified as a genetic risk factor for NSCLP in patients from Norway, the Philippines, and South America. Given the considerable variation in allele frequencies across these geographical regions, this study explored the relationship between NSCLP and mutations of PVRL1 in patients from Guangdong, China. We recruited 171 NSCLP patients and 100 volunteers, and divided our samples into 2 groups: a sequencing group and a mass spectrometry group. In the sequencing group, we screened for mutations in exons 2 and 5 of PVRL1 by polymerase chain reaction and direct sequencing in 71 NSCLP patients and 100 volunteers. In the mass spectrometry group, we screened for amino acid mutations in α-spliced transcript codons 112, 131, and 395, and in the β-spliced transcript codon 1082 using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis in 100 NSCLP patients and 100 volunteers. No mutations were detected in either PVRL1 exons 2 or 5 in the 71 NSCLP patients and 100 volunteers, nor did we find mutations of α-spliced transcript codons 112, 131, 395 and the β-spliced transcript codon 1082 in any of the 100 NSCLP patients and 100 volunteers. Thus, mutations in exons 2 and 5 of PVRL1, and T334A, A391T, G1183A in the α-spliced transcript, and G1082T in the β-spliced transcript do not participate in the development of NSCLP in patients from Guangdong.

Abstract
INTRODUCTION Cerebral infarction in tuberculous meningitis is a major risk factor for permanent disability. This study assessed the clinical presentation of tuberculous meningitis and risks factors for cerebral infarction. OBSERVATION Thirty-eight adult patients with tuberculous meningitis were studied between 2002 and 2006. Clinical, radiological, and laboratory data of patients with cerebral infarction were compared with those of patients without cerebral infarction. Patients with cerebral infarction were significantly older (65.1 vs 52.1years), had higher risk assessment scores (3.7 vs 2.2), and more often had basal meningeal enhancement on imaging (92.3% vs 60.0%), mild to moderate sequelae (69.2% vs 4%), an overall poor brain outcome (69.2% vs 8%), aspirin prescription (84% vs 8%), and neurosurgical intervention for hydrocephalus (54.0% vs 16.0%). Cerebral infarction patients were also more likely to have experienced doctor-related delays in antituberculosis (61.5% vs 36%) and corticosteroid (61.5% vs 32%) therapy. DISCUSSION AND CONCLUSION The Framingham risk score would be an option for tuberculous meningitis patients to access cerebral infarction risk. Contrast-enhanced brain imaging is helpful for exploring basal meningeal enhancement, in order to obtain an early diagnosis. Antituberculosis, corticosteroid, and aspirin therapies should be started immediately when tuberculous meningitis is suspected.

Abstract
BACKGROUND A mouse is an important communication interface between a human and a computer, but it is still difficult to use for the elderly or disabled. OBJECTIVE To develop a low-cost computer mouse auxiliary tool. METHODS The principal structure of the low-cost mouse auxiliary tool is the IR (infrared ray) array module and the Wii icon sensor module, which combine with reflective tape and the SQL Server database. RESULTS This has several benefits including cheap hardware cost, fluent control, prompt response, adaptive adjustment and portability. Also, it carries the game module with the function of training and evaluation; to the trainee, it is really helpful to upgrade the sensitivity of consciousness/sense and the centralization of attention. The intervention phase/maintenance phase, with regard to clicking accuracy and use of time, p value (p< 0.05) reach the level of significance. CONCLUSIONS The development of the low cost adaptive computer mouse auxiliary tool was completed during the study and was also verified as having the characteristics of low cost, easy operation and the adaptability. To patients with physical disabilities, if they have independent control action parts of their limbs, the mouse auxiliary tool is suitable for them to use, i.e. the user only needs to paste the reflective tape by the independent control action parts of the body to operate the mouse auxiliary tool.

Abstract
BACKGROUND People use upper limbs to conduct daily activities. When recovering from injuries, many patients neglect the importance of rehabilitation, which results in degraded function. OBJECTIVE Rehabilitation after treatment of an injury is very important. This study proposes to improve and enhance the effectiveness of rehabilitation practice. METHODS A patient record of the training process using the traditional rehabilitation hand gliding cart is produced by using a magnetic sensing element in the panel, a servo host computer, and other devices. RESULTS Clinical evidence shows that the training aids help significantly with the rehabilitation of patients with impaired upper limb function and reduce negative impacts from the disability in daily life and activities. CONCLUSIONS This study has combined the gliding cart with reed switches, such that when the patient moves the cart, the movement tracks can be observed via the activated reed switches. The training data are collected and quantified for a better understanding of the recovery status of the patients. Each of the participating patients makes progress as expected.

Abstract
OBJECTIVE Repairing articular cartilage is clinically challenging. We investigated a simple, effective and clinically feasible cell-based therapeutic approach using a poly(lactide-co-glycolide) (PLGA) scaffold seeded with autologous endothelial progenitor cells (EPC) to repair a full-thickness osteochondral defect in rabbits using a one-step surgery. METHODS EPC obtained by purifying a small amount of peripheral blood from rabbits were seeded into a highly porous, biocompatible PLGA scaffold, namely, EPC-PLGA, and implanted into the osteochondral defect in the medial femoral condyle. Twenty two rabbits were randomized into one of three groups: the empty defect group (ED), the PLGA-only group or the EPC-PLGA group. The defect sites were evaluated 4 and 12 weeks after implantation. RESULTS At the end of testing, only the EPC-PLGA group showed the development of new cartilage tissue with a smooth, transparent and integrated articular surface. Moreover, histological analysis showed obvious differences in cartilage regeneration. At week 4, the EPC-PLGA group showed considerably higher TGF-β2 and TGF-β3 expression, a greater amount of synthesized glycosaminoglycan (GAG) content, and a higher degree of osteochondral angiogenesis in repaired tissues. At week 12, the EPC-PLGA group showed enhanced hyaline cartilage regeneration with a normal columnar chondrocyte arrangement, higher SOX9 expression, and greater GAG and collagen type II (COLII) content. Moreover, the EPC-PLGA group showed organized osteochondral integration, the formation of vessel-rich tubercular bone and significantly higher bone volume per tissue volume and trabecular thickness (Tb.Th). CONCLUSION The present EPC-PLGA cell delivery system generates a suitable in situ microenvironment for osteochondral regeneration without the supplement of exogenous growth factors.

Abstract
BACKGROUND Many studies support the role of bilirubin as a cytoprotector in chronic inflammatory diseases, such as stroke and atherosclerosis. AIM To investigate the relationship between serum total bilirubin levels and functional dependence in older adults. METHODS Data from the National Health and Nutrition Examination Survey (1999-2002) pertaining to 2235 old adults were analysed. All participants had given a household interview, providing information of five major domains on self-reported functional status (activities of daily living, instrumental activities of daily living, leisure and social activities, lower extremity mobility and general physical activities), had completed serum total bilirubin measurement, and a questionnaire regarding personal health. Poor performance was defined as experiencing difficulty with one or more items in a given domain. Functional dependence was defined as having three or more poor performances in the five major domains. Multiple logistic regression was performed together with quartile-based stratified odds ratio (OR) comparison and trend tests. RESULTS The OR of functional dependence for each standard deviation increment in the serum total bilirubin level was 0.56 (P = 0.002). After additional adjustment, the inverse association remained essentially unchanged. In quartile-based analysis, participants with higher quartiles of serum total bilirubin tended to have lower ORs of functional dependence. The trends of lower likelihood of functional dependence across increasing quartiles of the serum total bilirubin level were statistically significant (P < 0.05 for all trends). CONCLUSIONS Higher serum total bilirubin levels were associated with lower likelihood of functional dependence in older adults.

Abstract
Effects of highly hygroscopic sorbitol, citric acid, sodium carboxymethyl cellulose or polyvinylpolypyrrolidone, on the hydrolysis of simvastatin in tablets at 25°/90% RH were studied. The simvastatin tablets were prepared by direct powder compression. Simvastatin and its hydrolyte, simvastatin acid, were quantitatively analysed by high performance liquid chromotography. The hygroscopicity, water swelling ratio, water solubility and pH of the four hygroscopic excipients were investigated. During the investigation period, the weight gain of sorbitol or citric acid increased faster than that of polyvinylpolypyrrolidone or sodium carboxymethyl cellulose at 25°/90% RH, accordingly, the moisture sorption of the tablets containing citric acid or sorbitol (T-3 or T-6) were more than that of the tablets containing sodium carboxymethyl cellulose or polyvinylpolypyrrolidone (T-4 or T-5). The increase of simvastatin acid content with time at 25°/90% RH for the tablets was in the following order: T-6 < T-4 < T-3 < T-5. The effects of the four excipients on the hydrolysis of simvastatin in tablet were related to not only their hygroscopicity but also their other properties, such as moisture retention capacity and pH. Sorbitol as hygroscopic excipient in tablet can most effectively prevent the hydrolysis of simvastatin in tablet.

Abstract
We compared the outcomes of endovascular coiling with microsurgical clipping of aneurysms in a Taiwanese population. In an ambi-directional cohort design, patient baseline characteristics and clinical course after treatment for ruptured subarachnoid aneurysm were abstracted from medical records from three hospitals to examine and compare differences in post-operative outcomes between those treated with endovascular coiling and those treated with microsurgical clipping. Outcomes were measured, using the modified Rankin scale, two months, one year and two years postoperatively. Of the 642 patients enrolled in the study, 281 underwent endovascular treatment and 361 underwent neurosurgery. The demographics and baseline characteristics of two groups were comparable except for a larger maximum target aneurysm lumen size (p=0.02) in the endovascular group. Patients who underwent the endovascular procedure tended to have a better quality of life than those who had neurosurgery (p<0.01). When the severity of symptom data was pooled into two groups (Rankin values 0-2 and 3-6) a statistically significant relationship was found between the severity of symptoms and age, Hunt and Hess grade, number of target aneurysms detected, and log of maximum target aneurysm lumen size (all p≤0.01). After controlling for potential confounding factors and using the lumped Rankin outcome data, no significant difference in outcome was found between the two procedures at either time point. Our study indicated that endovascular coiling achieves results comparable to surgical clipping for patients with ruptured subarachnoid aneurysms in a Taiwanese population.

Abstract
A liquid chromatography/tandem mass spectrometry (LC-MS/MS) method was developed to determine concentrations of posaconazole in human plasma precipitated by acetonitrile including internal standard. Rapid chromatographic separation was achieved in the mobile phase composition of acetonitrile, water and formic acid (v/v/v, 55:45:0.1) with a flow rate of 0.25 ml/min. Posaconazole-d4 was used as internal standard. Detection was undertaken with cation electrospray tandem mass spectrometry on a Sciex/API3000. The method was accurate, specific and sensitive for the analysis of posaconazole in human plasma in the concentration range of 2-1000 ng/ml. The inter- and intra-batch accuracy was within +/- 10% and the lower limit of quantification was 2 ng/ml. The method facilitated a clinical pharmacokinetic study after oral administration of a single-dose of posaconazole suspension in the fasted state and with a high-fat meal in a two-period crossover design. Cmax (maximum concentration) and AUC (area under serum drug concentration) were significantly increased, and Tmax (time to maximum plasma concentration) was delayed under fed condition, which suggested that simultaneous administration of posaconazole with food may help to achieve higher plasma concentrations and result in better antifungal efficacy.

Abstract
We demonstrate a fiber-based multiple-access ultrastable frequency dissemination scheme over an 83 km fiber link. As a performance test, we reproduce the disseminated 9.1 GHz radio-frequency modulation signal at an arbitrary point in the dissemination channel. Relative frequency stability of 7×10(-14)/s and 5×10(-18)/day is obtained. Highly synchronized frequency signals can be regenerated along the entire fiber pathway and its applications are discussed.

Abstract
BACKGROUND Although intravenous tissue-type plasminogen activator (t-PA) at a standard dose of 0.9 mg kg(-1) is effective for patients with acute ischemic stroke, concerns have been raised regarding Asians. OBJECTIVES To compare the safety and efficacy between low and standard doses for stroke thrombolysis. PATIENTS/METHODS Consecutive patients receiving t-PA treatment were recruited according to the prespecified dosing policy from two medical centers in Taiwan: low dose (0.7 mg kg(-1) ) at National Cheng Kung University Hospital (NCKUH) from August 2006 to June 2009, or standard dose (0.9 mg kg(-1) ) at NCKUH from July 2009 to December 2010 and at Changhua Christian Hospital from May 2008 to December 2010. The primary safety outcome was the occurrence of symptomatic intracerebral hemorrhage (SICH). The secondary efficacy outcome was the proportion of patients with a modified Rankin Scale (mRS) grade of ≤ 1 at 3 months. RESULTS From August 2006 to December 2010, 261 patients were recruited, of whom 105 and 156 received low and standard doses, respectively. The occurrence of SICH was non-significantly lower in the standard-dose group than in the low-dose group (2.6% vs. 4.8%, respectively; P = 0.34). The favorable outcome of mRS grade of ≤ 1 at 3 months was similar (38.4% and 41.1%, respectively; P = 0.676). A review of other case series of low vs. standard doses in Asians also showed similar safety and efficacy. CONCLUSION Our study, as well as other case series on Asians, revealed that standard-dose thrombolysis for acute ischemic stroke in an Asian population carries no increased risk of symptomatic intracerebral hemorrhage when compared with the low dose.

Abstract
AIMS/HYPOTHESIS Sirtuin 1 (SIRT1) is a longevity-associated protein, which regulates energy metabolism and lifespan in response to nutrient deprivation. It has been proposed to be a therapeutic target for obesity and metabolic syndrome. We investigated whether α-lipoic acid (ALA) exerts a lipid-lowering effect through regulation of SIRT1 activation and production in C(2)C(12) myotubes. METHODS ALA-stimulated AMP-activated protein kinase (AMPK), acetyl-CoA carboxylase (ACC), adipose triacylglycerol lipase (ATGL) and fatty acid synthase (FAS) production, as well as intracellular triacylglycerol accumulation and fatty acid β-oxidation were analysed in the absence or presence of a SIRT1 inhibitor (nicotinamide), SIRT1 small interfering (si) RNA and an AMPK inhibitor (compound C) in C(2)C(12) myotubes. Mice with streptozotocin/nicotinamide-induced diabetes and db/db mice fed on a high-fat diet were used to study the ALA-mediated lipid-lowering effects in vivo. RESULTS ALA increased the NAD(+)/NADH ratio to enhance SIRT1 activity and production in C(2)C(12) myotubes. ALA subsequently increased AMPK and ACC phosphorylation, leading to increased palmitate β-oxidation and decreased intracellular triacylglycerol accumulation in C(2)C(12) myotubes. In cells treated with nicotinamide or transfected with SIRT1 siRNA, ALA-mediated AMPK/ACC phosphorylation, intracellular triacylglycerol accumulation and palmitate β-oxidation were reduced, suggesting that SIRT1 is an upstream regulator of AMPK. ALA increased ATGL and suppressed FAS protein production in C(2)C(12) myotubes. Oral administration of ALA in diabetic mice fed on a high-fat diet and db/db mice dramatically reduced the body weight and visceral fat content. CONCLUSIONS/INTERPRETATION ALA activates both SIRT1 and AMPK, which leads to lipid-lowering effects in vitro and in vivo. These findings suggest that ALA may have beneficial effects in the treatment of dyslipidaemia and obesity.

Abstract
BACKGROUND AND PURPOSE Little information exists on the mechanisms that precipitate brain stem death, the legal definition of death in many developed countries. We investigated the role of tropomyocin receptor kinase B (TrkB) and its downstream signalling pathways in the rostral ventrolateral medulla (RVLM) during experimental brain stem death. EXPERIMENTAL APPROACH An experimental model of brain stem death that employed microinjection of the organophosphate insecticide mevinphos bilaterally into the RVLM of Sprague-Dawley rats was used, in conjunction with cardiovascular, pharmacological and biochemical evaluations. KEY RESULTS A significant increase in TrkB protein, phosphorylation of TrkB at Tyr(516) (pTrkB(Y516) ), Shc at Tyr(317) (pShc(Y317) ) or ERK at Thr(202) /Tyr(204) , or Ras activity in RVLM occurred preferentially during the pro-life phase of experimental brain stem death. Microinjection bilaterally into RVLM of a specific TrkB inhibitor, K252a, antagonized those increases. Pretreatment with anti-pShc(Y317) antiserum, Src homology 3 binding peptide (Grb2/SOS inhibitor), farnesylthioacetic acid (Ras inhibitor), manumycin A (Ras inhibitor) or GW5074 (Raf-1 inhibitor) blunted the preferential augmentation of Ras activity or ERK phosphorylation in RVLM and blocked the up-regulated NOS I/protein kinase G (PKG) signalling, the pro-life cascade that sustains central cardiovascular regulation during experimental brain stem death. CONCLUSIONS AND IMPLICATIONS Activation of TrkB, followed by recruitment of Shc/Grb2/SOS adaptor proteins, leading to activation of Ras/Raf-1/ERK signalling pathway plays a crucial role in ameliorating central cardiovascular regulatory dysfunction via up-regulation of NOS I/PKG signalling cascade in the RVLM in brain stem death. These findings provide novel information for developing therapeutic strategies against this fatal eventuality.

Abstract
Schwannomas are rare tumours arising from the peripheral nerve sheath. Nearly half of all schwannomas occur in the head and neck region, but the sinonasal tract is rarely involved. We report on an extremely rare case of vidian nerve schwannoma accompanied by mucopyocele with symptoms of oculomotor palsy and CSF leakage. An exclusively endoscopic endonasal approach was performed to excise the tumour and the dural defect was repaired. To our knowledge, this is the first time a vidian nerve schwannoma has been excised in an exclusively endoscopic approach. We first review the literature and then discuss the benefits for patients undergoing this type of operation.
