Abstract
Objective: To explore the role of prognostic nutritional index (PNI) and pleural thickness in the prognostic evaluation of patients with epithelial malignant pleural mesothelioma (MPM) . Methods: In April 2022, a retrospective analysis was conducted on the data and laboratory data of 41 patients with epithelial MPM admitted to the cardiothoracic surgery department of Chuxiong Yi Autonomous Prefecture People's Hospital from January 2018 to May 2021. Univariate and multivariate analysis were used to evaluate the relationships between total survival time, clinical characteristics, PNI and pleural thickness in patients. Results: The 41 patients were mostly male (26 cases, 63.4%) , with a median age of 55 years old. The main clinical manifestations were chest pain (53.7%) , bloody pleural effusion (75.6%) , and chest pain combined with bloody pleural effusion (36.6%) . The median survival time of patients with different TNM stage, efficacy after 4 cycles of chemotherapy, PNI, maximum pleural thickness after chemotherapy (post max) , sum of post max in 3 zones after chemotherapy (post sum) were statistically different (χ(2)=3.89, 14.51, 15.33, 4.33, 12.05, P<0.05) . Compared with patients with high PNI and post sum<32.26 mm, MPM patients with low PNI and post sum≥32.26 mm have higher risk of death, and the differences were statistically significant (HR=1.52, 95%CI: 1.75-11.93, P=0.002; HR=1.70, 95%CI: 1.84-16.23, P=0.002) . Conclusion: PNI and post sum can be used to predict the prognosis of patients with epithelial MPM.

Abstract
Objective: To analyze the incidence trend and epidemiological characteristics of typhoid fever in Fujian Province from 2011 to 2022, and understand the high-incidence population and hotspot areas, and provide evidences to develop more targeted prevention and control measures. Methods: The surveillance data of typhoid fever during 2011-2022 in Fujian Province were obtained from the National Disease Reporting Information System and analyzed with SAS 9.4. The spatial autocorrelation analysis of typhoid fever incidence at county/district levels was performed with ArcGlS 10.8. Results: A total of 5 126 cases of typhoid fever were reported in Fujian Province from 2011 to 2022, with an average annual incidence rate of 1.10/100 000. The average annual incidence rate was 0.96/100 000 from 2011 to 2015, 1.49/100 000 from 2016 to 2019, and 0.81/100 000 from 2020 to 2022. The disease occurred all the year round, with high epidemic season from May to September. A total of 23.59% (1 209/5 126) of the cases occurred at the age of 0-4, and 9.62% (493/5 126) at the age of 5-9. The male to female ratio of the cases was 0.97∶1 (2 524∶2 602) for the whole population, 1.19∶1 (925∶777) for people under 10 years old, 0.75∶1 (1 060∶1 404) for people between 10 and 54 years old, and 1.28∶1 (539∶421) for people over 55 years old. Cases in Ningde City accounted for 30.65% (1 571/5 126) of the total cases. Most hotspots were occurred in Ningde City. Recurrent and clustered cases were found in family members. Conclusions: Typhoid fever was prevalent at a low level in Fujian Province during 2011-2022, indicating that strengthening the prevention and control measures should target key areas and populations. The incidence of typhoid fever in Fujian Province showed spatial aggregation phenomenon, and most cases gathered in Ningde City. Intensive study for the influencing factors of spatial clustering should be conducted.

Abstract
Surgery is the mainstay of treatment for meningioma, the most common primary intracranial tumor, but improvements in meningioma risk stratification are needed and indications for postoperative radiotherapy are controversial. Here we develop a targeted gene expression biomarker that predicts meningioma outcomes and radiotherapy responses. Using a discovery cohort of 173 meningiomas, we developed a 34-gene expression risk score and performed clinical and analytical validation of this biomarker on independent meningiomas from 12 institutions across 3 continents (N = 1,856), including 103 meningiomas from a prospective clinical trial. The gene expression biomarker improved discrimination of outcomes compared with all other systems tested (N = 9) in the clinical validation cohort for local recurrence (5-year area under the curve (AUC) 0.81) and overall survival (5-year AUC 0.80). The increase in AUC compared with the standard of care, World Health Organization 2021 grade, was 0.11 for local recurrence (95% confidence interval 0.07 to 0.17, P < 0.001). The gene expression biomarker identified meningiomas benefiting from postoperative radiotherapy (hazard ratio 0.54, 95% confidence interval 0.37 to 0.78, P = 0.0001) and suggested postoperative management could be refined for 29.8% of patients. In sum, our results identify a targeted gene expression biomarker that improves discrimination of meningioma outcomes, including prediction of postoperative radiotherapy responses.

Abstract
Background The aim of this study is to address the paucity of epidemiological data regarding the characteristics, treatment patterns and survival outcomes of Chinese glioblastoma patients. Methods This was a population-level study of Hong Kong adult (>18 years) Chinese patients with newly diagnosed histologically confirmed glioblastoma between 2006 and 2019. The age standardized incidence rate (ASIR), patient-, tumor- treatment-related characteristics, overall survival (OS) as well as its predictors were determined. Results One thousand and ten patients with a median follow-up of 10.0 months were reviewed. The ASIR of glioblastoma was 1.0 per 100 000 population with no significant change during the study period. The mean age was 57 + 14 years. The median OS was 10.6 months (IQR: 5.2-18.4). Independent predictors for survival were: Karnofsky performance score >80 (adjusted OR: 0.8; 95% CI: 0.6-0.9), IDH-1 mutant (aOR: 0.7; 95% CI: 0.5-0.9) or MGMT methylated (aOR: 0.7; 95% CI: 0.5-0.8) glioblastomas, gross total resection (aOR: 0.8; 95% CI: 0.5-0.8) and temozolomide chemoradiotherapy (aOR 0.4; 95% CI: 0.3-0.6). Despite the significant increased administration of temozolomide chemoradiotherapy from 39% (127/326) of patients in 2006-2010 to 63% (227/356) in 2015-2019 (P-value < .001), median OS did not improve (2006-2010: 10.3 months vs 2015-2019: 11.8 months) (OR: 1.1; 95% CI: 0.9-1.3). Conclusions The incidence of glioblastoma in the Chinese general population is low. We charted the development of neuro-oncological care of glioblastoma patients in Hong Kong during the temozolomide era. Although there was an increased adoption of temozolomide chemoradiotherapy, a corresponding improvement in survival was not observed.

Abstract
INTRODUCTION In contrast to standard-of-care treatment of newly diagnosed glioblastoma, there is limited consensus on therapy upon disease progression. The role of resection for recurrent glioblastoma remains unclear. This study aimed to identify factors for overall survival (OS) and post-progression survival (PPS) as well as to validate an existing prediction model. METHODS This was a multi-centre retrospective study that reviewed consecutive adult patients from 2006 to 2019 that received a repeat resection for recurrent glioblastoma. The primary endpoint was PPS defined as from the date of second surgery until death. RESULTS 1032 glioblastoma patients were identified and 190 (18%) underwent resection for recurrence. Patients that had second surgery were more likely to be younger (<70 years) (adjusted OR: 0.3; 95% CI: 0.1-0.6), to have non-eloquent region tumours (aOR: 1.7; 95% CI: 1.1-2.6) and received temozolomide chemoradiotherapy (aOR: 0.2; 95% CI: 0.1-0.4). Resection for recurrent tumour was an independent predictor for OS (aOR: 1.5; 95% CI: 1.3-1.7) (mOS: 16.9 months versus 9.8 months). For patients that previously received temozolomide chemoradiotherapy and subsequent repeat resection (137, 13%), the median PPS was 9.0 months (IQR: 5.0-17.5). Independent PPS predictors for this group were a recurrent tumour volume of >50cc (aOR: 0.6; 95% CI: 0.4-0.9), local recurrence (aOR: 1.7; 95% CI: 1.1-3.3) and 5-ALA fluorescence-guided resection during second surgery (aOR: 1.7; 95% CI: 1.1-2.8). A National Institutes of Health Recurrent Glioblastoma Multiforme Scale score of 0 conferred an mPPS of 10.0 months, a score of 1-2, 9.0 months and a score of 3, 4.0 months (log-rank test, p-value < 0.05). CONCLUSION Surgery for recurrent glioblastoma can be beneficial in selected patients and carries an acceptable morbidity rate. The pattern of recurrence influenced PPS and the NIH Recurrent GBM Scale was a reliable prognostication tool.

Abstract
Objective: To analyze the prognosis and risk factors of lung metastasis of patients with adenoid cystic carcinoma(ACC) of head and neck. Methods: A retrospective study was conducted. The data of 157 patients with ACC of head and neck treated in Beijing Tongren Hospital, Capital Medical University from January 2014 to October 2020 were collected, including 72 males and 85 females, with onset age between 14 and 72 years old. According to whether lung metastasis occurred, the patients were divided into lung metastasis group (88 cases) and non-pulmonary metastasis group (69 cases). Kaplan-Meier method was used to calculate the overall survival rate and progression-free survival rate using SPSS 26.0 software. Log-rank test was used to evaluate statistically relevant clinicopathological factors. Cox proportional risk model was used in multivariate analysis for the factors affecting the lung metastasis-free survival using R Studio 1.2.5042. Results: The 3-year and 5-year overall survival rates were 91.5% and 85.2%, respectively. The 3-year and 5-year progression-free survival rates were 57.7% and 34.3%, respectively. Univariate analysis showed that primary site, histological grade, high-grade transformation, Ki-67, T stage, and lymph node status were the risk factors for lung metastasis (χ2=11.78, 10.41, 4.06, 4.71, 5.37, 16.20, respectively, all P<0.05). Multivariate analysis showed independent risk factors for lung metastasis, including submandibular gland and sublingual gland (HR=3.53, 95%CI: 1.19-10.46, P<0.05), T3-4 stage (HR=3.09, 95%CI: 1.54-6.23, P<0.05), and Grade Ⅱ-Ⅲ grade (HR=2.47, 95%CI: 1.26-4.86,P<0.05). Conclusion: Distant metastasis, mainly pulmonary metastasis, affects the long-term prognosis of patients with ACC significantly. Primary site, T stage and histopathological grade can be used as the predictors for the risk of lung metastasis.

Abstract
Subjective To investigate clinical characteristics, treatment, and prognosis of lymphoma-associated hemophagocytic syndrome (LAHS) patients. Methods: The clinical data of patients diagnosed with LAHS from January 2010 to October 2021 in West China Hospital were retrospectively analyzed. Clinical characteristics, treatment, overall response rate (ORR), and overall survival (OS) were investigated. Univariate and multivariate analysis of potential factors were conducted. Results: Of all 94 patients included, 59 were male and 35 were female. The age at hemophagocytic lymphohistiocytosis (HLH) diagnosis was (40.5±17.3) years. Seventy-four cases were T/NK cell lymphoma; 15 were B cell lymphoma; 5 were Hodgkin lymphoma. The age at HLH diagnosis of T/NK cell LAHS patients was (37.9±16.2) years, while that of B cell LAHS patients was (55.9±14.0) years. T/NK cell LAHS patients were significantly younger than B cell LAHS patients (P<0.001). Baseline fibrinogen of T/NK cell LAHS patients was 1.34 (0.86, 2.44) g/L, while that of B cell LAHS patients was 2.20 (1.75, 4.25) g/L. T/NK cell LAHS patients showed significantly lower fibrinogen levels than B cell LAHS patients (P=0.008). Combined treatment of anti-HLH and anti-lymphoma treatment was conducted in 35 patients; anti-HLH treatment was conducted in 31 patients; anti-lymphoma treatment was conducted in 8 patients; glucocorticoid treatment was conducted in 7 patients. ORR was 49.4%, and the median OS was 61 days for overall patients. Patients who received anti-HLH treatment and turned to anti-lymphoma treatment early displayed the best ORR and OS, significantly higher than those of anti-HLH patients (69.0 vs 38.7%, P=0.019, and 192.0 vs 24.5 days, P=0.028, respectively), which were also insignificantly higher than those of anti-lymphoma patients. Extranodal NK/T-cell lymphoma or aggressive natural killer cell leukemia was the risk factor of LAHS prognosis (HR=0.113, 95%CI: 0.018-0.728, P=0.022). Conclusions: Prognosis of LAHS patients is poor. Anti-lymphoma treatment should be initiated as soon as HLH is rapidly controlled.

Abstract
Objective: To analyze the repetitive reporting of hepatitis B in Fujian province during 2016-2020, and provide evidence for the improvement of hepatitis B surveillance. Methods: The reporting cards from the China Information System for Disease Control and Prevention were collected and divided into repetitive reporting cards and non-repetitive reporting cards from the report cards collected according to the valid ID number on the cards, and the proportion of repetitive report cards and related factors were analyzed by using software SAS 9.4. Results: A total of 314 551 hepatitis B reporting cards were submitted in Fujian from 2016 to 2020, in which 90.93% (286 020/314 551) were included in the analysis. The repetitive reporting cards accounted for 10.48% (29 982/286 020). The annual proportion of the repetitive reporting cards from 2016 to 2020 was between 2.98% and 3.71%, showing an overall increasing trend year by year (Z=2.26, P=0.024). The proportions of the repetitive reporting cards in 1-5 years were 3.17%, 5.40%, 7.74%, 9.27% and 10.48%, respectively, showing an increase trend with year (Z=128.16, P<0.001). The proportions of the repetitive reporting cards in 10 areas of Fujian ranged from 5.44% to 13.48% with significant difference (χ2=2 050.41, P<0.001) and increased with the increase of reported incidence of hepatitis B (Z=26.92, P<0.001). There were significant differences in relationships between repetitive reporting proportion and sex, age and type of the cases between the areas with high incidence and low incidence of hepatitis B. Conclusions: The reported incidence of hepatitis B was seriously affected by the repetitive reporting in Fujian from 2016 to 2020. A cross-year and cross-area surveillance mechanism for hepatitis B should be established and targeted measures should be taken to strengthen the control of the repetitive reporting and improve the surveillance for hepatitis B.

Abstract
Objective: To explore the efficacy of relocation and expansion pharyngoplasty by suspension sutures in the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: Seventy-three patients(including 60 males and 13 females) with OSAHS admitted to the department of otorhinolaryngology of our hospital in recent two years were retrospectively analyzed. All the patients had velopharyngeal obstructionevaluated by electronic endoscopic Müller test and were divided into control group (34 cases) and observation group (39 cases). The patients in the control group were performed modified uvulopalatopharyngoplasty, while those in the observation group were performed relocation and expansion pharyngoplasty by suspension sutures.The scores of ESS, AHI and LSaO2 before and after treatment were collected and compared. Results: The total effective rate of the observation group was 94.87%, which was significantly higher than 79.41% of the control group. The AHI was lower and LSaO2 value was higher (χ2=-1. 896,-1. 968,P<0.05)in the observation group. The sleeping symptoms and quality of life of the two groups were significantly improved. The ESS score of the observation group was decreased more significantly than that of the control group after treatment, and the difference was statistically significant (χ2=-1.451,P<0.05). The incidence of foreign body sensation in pharynx of the observation group (89.74%) was higher than that of the control group (55.88%), and the postoperative bleeding and postoperative recurrence rate (0.00%, 2.56%) was lower than that of the control group (8.82%, 14.70%)with statistical significance (χ2=4.738,4.249,4.119,P<0.05).The incidence of transient nasopharyngeal reflux in both groups was low and statistically insignificant (χ2=0.629,P>0.05). Conclusions: Preoperative strict screening of indications plays an important role in the selection of palatopharyngeal surgery methods and curative effect. Relocation and expansion pharyngoplasty by suspension sutures can improve the clinical efficacy of OSAHS with better safety and less recurrence.

Abstract
Abstract
BACKGROUND
Surgery is the mainstay of meningioma treatment, but improvements in meningioma risk stratification are needed and indications for postoperative radiotherapy are controversial. DNA methylation profiling, copy number variants (CNVs), exome sequencing, and RNA sequencing have improved understanding of meningioma biology, but have not superseded histologic grading, or revealed biomarkers for radiotherapy responses. To address these unmet needs, we optimized and validated a targeted gene expression biomarker predicting meningioma outcomes and responses to radiotherapy.
METHODS
Targeted gene expression profiling was performed on a discovery cohort of 173 meningiomas (median follow-up 8.1 years) and a validation cohort of 331 meningiomas (median follow-up 6.1 years) treated with surgery (n=504) and postoperative radiotherapy (n=73) at independent, international institutions (70% WHO grade 1, 24% WHO grade 2, 6% WHO grade 3). Optimized targeted gene expression models predicting clinical outcomes (34 genes) or radiotherapy responses (12 genes) were developed from the discovery cohort, and compared to histologic and molecular classification systems by performing DNA methylation profiling, CNV analysis, exome sequencing, and RNA sequencing on the same meningiomas.
RESULTS
Targeted gene expression profiling achieved a concordance-index of 0.75 ± 0.03 (SEM) for local freedom from recurrence (LFFR) and 0.72 ± 0.03 for overall survival (OS) in the validation cohort, outperforming WHO grade (5-year LFFR delta-AUC 0.15, 95% CI 0.076-0.229, p=0.001) and DNA methylation grouping (delta-AUC 0.075, 95% CI 0.006-0.130, p=0.01) for LFFR, disease-specific survival, and OS. The biomarker was independently prognostic after accounting for WHO grade, extent of resection, primary versus recurrent presentation, CNV status, DNA methylation group, and Ki67 labeling index, and identified meningiomas benefiting from radiotherapy (interaction p-value=0.0008), suggesting postoperative radiotherapy could be refined in 30.2% of cases.
CONCLUSIONS
Targeted gene expression profiling of 504 meningiomas improves discrimination of meningioma local recurrence, disease-specific survival, and overall survival, and predicts radiotherapy responses.

Abstract
Myoepithelial tumors are rare neoplasms that develop from myoepithelial cells in glandular structures and soft tissues. Primary intracranial myoepithelial neoplasms are even rarer with around ten cases reported. On the other hand, adrenocortical carcinoma (ACC) is also uncommon with an annual incidence of 0.7–2 per million and carries a poor prognosis. It is known to have an association with certain familial cancer syndromes. Even in sporadic cases, a significant portion of them had other malignancies before and after diagnosis of ACC. We reported a 34-year-old gentleman who was diagnosed to have ACC without known familial cancer syndrome. After that, he was also found to have right occipital myoepithelioma that was confirmed by excisional biopsy. There was no known association between these two pathologies. This is the first report of coincidence of ACC and intracranial myoepithelioma.

Abstract
BACKGROUND Surgical treatment of intrathoracic meningoceles, commonly associated with neurofibromatosis type 1 (NF1), aims to reduce sac size for symptomatic relief. The procedures can be divided into cerebrospinal fluid diversion and definitive repair. The authors describe the management of an intrathoracic meningocele in a 56-year-old female with preexisting NF1. OBSERVATIONS The patient presented with progressive dyspnea. Magnetic resonance imaging revealed a left hemithoracic meningocele arising from the thecal sac at C7–T2. Two attempts at diversion by cystoperitoneal shunts resulted in recurrence. For definitive repair, T2–3 costotransversectomy was performed, and intradural closure of the meningocele opening was performed utilizing spinal dura and autologous fascia lata graft. Trapezius muscle regional flap was turned for reinforcement. Persistent leak warranted reoperation 7 days later. A transthoracic approach was undertaken using video-assisted thoracoscopic resection of the sac at aortic arch level, with reinforcement by latissimus dorsi flap and synthetic materials. Mechanical pleurodesis was performed. Intradural repair of the meningocele opening was revised. LESSONS Inherent dural abnormality makes repair difficult for meningoceles associated with NF1. A combined intradural and thoracoscopic approach with regional muscle flap and synthetic material reinforcement is a unique method for definitive treatment. Some essential points of perioperative management are highlighted.

Abstract
目的 筛选并分析与弥漫大B细胞淋巴瘤(DLBCL)预后相关的免疫表型,探究其预后价值。 方法 选取天津医科大学肿瘤医院2011年1月至2016年12月收治的163例DLBCL患者,免疫组织化学染色检测DLBCL常见免疫表型,COX模型探索独立于国际预后指数(IPI)影响总生存(OS)与无进展生存(PFS)的免疫表型,并分析其两两联合表达对预后的影响。 结果 多因素分析显示BCL6阴性(PFS:HR=1.652,95% CI 1.030~2.649,P=0.037)、P53阳性(OS:HR=1.842,95% CI 1.008~3.367,P=0.047)、BCL2强阳性(OS:HR=2.102,95%CI 1.249~3.537,P=0.005;PFS:HR=2.126,95% CI 1.312~3.443,P=0.002)是DLBCL中独立于IPI的预后不良因素。亚组分析显示,在年龄≤60岁组患者中BCL6阴性(PFS:HR=2.042,95%CI 1.021~4.081,P=0.043)、P53阳性(OS:HR=3.069,95% CI 1.244~7.569,P=0.015)和BCL2强阳性(OS:HR=2.433,95% CI 1.165~5.082,P=0.018;PFS:HR=3.209,95%CI 1.606~6.410,P=0.001)对预后影响显著;在IPI 0~2分亚组患者中,BCL6阴性(OS:HR=2.467,95%CI 1.322~4.604,P=0.005;PFS:HR=2.248,95%CI 1.275~3.965,P=0.005)和BCL2强阳性(PFS:HR=2.045,95%CI 1.119~3.735,P=0.020)对预后影响显著。BCL6和BCL2强阳性的联合表达与DLBCL的预后相关(P=0.005和P<0.001),BCL6阳性/BCL2非强阳性(86例)预后最好[3年OS率(71.6±4.9)%,3年PFS率(67.0±5.1)%],BCL6阴性/BCL2强阳性(10例)预后最差[3年OS率(20.0±12.6)%,3年PFS率(10.0±9.5)%];BCL6、P53的联合表达与DLBCL的预后差异无统计学意义(P=0.061和P=0.089),但生存曲线显示BCL6阳性/P53阴性的病例(98例)预后较好[3年OS率(70.6±4.7)%,3年PFS率(64.6±4.9)%];BCL2强阳性、P53的联合表达与DLBCL的预后显著相关(P<0.001和P<0.001),BCL2强阳性/P53阳性的病例(5例)预后最差(3年OS率和PFS率均为0);无论BCL6与P53表达如何,BCL2强阳性的病例预后均比非强阳性病例差。 结论 BCL6阴性、P53阳性、BCL2强阳性三种免疫表型单独及联合表达对DLBCL尤其是年龄≤60岁和IPI 0~2分患者的预后预测具有一定价值。

Abstract
AIMS Acidithiobacillus caldus is an important sulphur-oxidizing bacterium that plays crucial roles in the bioleaching industry. This study aims to analyse the optimal reference gene for real-time quantitative PCR (RT-qPCR) under different conditions and investigate the transcription levels of the sigma factor genes in the stress response. METHODS AND RESULTS We selected six housekeeping genes and analysed them via RT-qPCR using two energy resources, under four stress conditions. Three statistical approaches BestKeeper, geNorm, and NormFinder were utilized to determine transcription stability of these reference genes. The gapdH gene was the best internal control gene using elemental sulphur as an energy resource and under heat stress, map was the best internal control gene under pH and osmotic stress, era was the best internal control gene for the K2 S4 O6 energy resource, and rpoC was the best internal control gene under Cu2+ stress. Furthermore, the expressional levels of 11 sigma factors were analysed by RT-qPCR in the stress response. CONCLUSIONS Stable internal control genes for RT-qPCR analysis of A. caldus were determined, and the expression patterns of sigma factor genes of A. caldus were investigated. SIGNIFICANCE AND IMPACT OF THE STUDY The identification of the optimal reference gene and analysis of transcription levels of sigma factors in A. caldus can provide clues for reference gene selection and the study of sigma factor function.

Abstract
Schisandra is a widely used herb in traditional Chinese medicine. It can maintain the balance of bone reconstruction and play an important role in promoting osteoblast differentiation, regulating osteoclast activity and protecting cartilage tissue. It provides a broad prospect for the treatment of osteoporosis, osteoarthritis and some other diseases. In this paper, the action mechanism of schisandra chinensis and its active components in bone reconstruction was reviewed in order to provide theoretical basis for its product development and application in bone tissue engineering.

Abstract
BACKGROUND Facial paresis is one of the complications after treatment for vestibular schwannoma (VS). Acupuncture has been used for Bell palsy but not in iatrogenic facial paresis. The objective of this study is to measure the efficacy of using acupuncture for iatrogenic facial nerve palsy and patients' satisfaction. METHODS This is a single-center retrospective study with patients from 2007-2019 received treatment for newly diagnosed or recurrent VS. Some patients who suffered facial paresis after surgery had self-initiated acupuncture. All patients who had facial paresis were included. Their facial nerve status before and immediately after surgery, postoperative 6 months and 12 months, were recorded. Those who received acupuncture also answered 6- and 12-month patient satisfaction surveys over the phone. Adverse effects were also assessed. RESULTS There were 123 patients in this period. Of these, 29 patients had iatrogenic facial paresis and 23 of them received acupuncture. There was significant improvement of facial paresis for the acupuncture group compared with the nonacupuncture group at 6 and 12 months. More than 80% of patients who received acupuncture were satisfied. They had motor improvement and experienced less pain and tightness. No adverse effects were reported. CONCLUSIONS Acupuncture for postresection VS facial paresis seemed to speed up its recovery. Both patients' recovery and satisfaction were good after acupuncture, and it seemed to be a safe procedure in trained hands.

Abstract
Gamma Knife radiosurgery (GKRS) is a frequent treatment choice for patients with small- to moderate-sized vestibular schwannoma (VS). However, pseudoprogression after GKRS is commonly observed, with a reported incidence ranging from 7% to 77%. The wide range of the reported incidence of pseudoprogression reflects the fact that there is no consensus on how it should be diagnosed. The authors present the case of a 66-year-old woman who had a 2.5-cm right-sided VS treated with GKRS in 1997. The first posttreatment MRI obtained 5 months later showed that the tumor volume had increased to 9.7 cm3. The tumor volume increased further and reached its peak 24 months after treatment at 20.9 cm3, which was a 161% increase from pretreatment volume. Thereafter, the tumor shrank gradually and mass effect on the brainstem reduced over time. By 229 months after treatment, the tumor volume was 1.0 cm3, equaling 12.5% of pretreatment tumor volume, or 4.8% of peak tumor volume after treatment. This case demonstrates that if a patient remains asymptomatic despite a dramatic increase in tumor volume after GKRS, observation remains an option, because even a very sizable tumor can shrink with near-complete resolution. Patients undergoing GKRS for VS should be counseled regarding the possibility of pseudoprogression, and followed carefully over time while avoiding premature decisions for surgical removal after treatment.

Abstract
One of the treatment options for long segment common carotid artery (CCA) occlusion is bypass surgery with different combinations of donors and receipts. Using vertebral artery (VA) as the donor for CCA occlusion was uncommonly reported. The reported cases were using jump graft to connect V3 segment of VA to either CCA or ICA. We describe our patient using V2 segment as the donor for VA-CCA bypass as treatment for CCA occlusion. Our patient was a 51 years old gentleman with Marfan syndrome and had multiple operations that included total arch replacement. He presented with sudden onset of spontaneous right frontal subarachnoid haemorrhage and repeated episodes of TIA with left upper limb numbness. CTA showed occluded right CCA and anastomosis between branches from subclavian artery and occipital artery. CT perfusion showed hypoperfusion of right hemisphere. To avoid damaging the anastomosis at subclavian artery and occipital artery, we decided for V2-RAG (radial artery graft)-CCA bypass. It was done by exposing the V2 segment at C4/5 level, performing end-to-side anastomoses at V2-RAG and RAG-CCA junctions where the RAG was underneath the internal jugular vein. Patient had no new deficits after surgery and no more TIAs. CTA performed one week after surgery showed patent RAG. In conclusion, using V2 for VA-CCA bypass is technically feasible and may have theoretical advantages over using V3. V2-CCA bypass is an option for CCA occlusion in very selected patients.

Abstract
Objective: To explore the effect and potential mechanism of cardiac adipose triglyceride lipase (ATGL) overexpression on burn-induced cardiac injury. Methods: Eight-week-old C57BL/6J mice with cardiac ATGL overexpression driven by the myosin heavy chain (MHC) promoter (MHC-ATGL burn group) and wild-type (wild-type burn group) mice were randomly chose to the following experiments with burn injury after 24 h (n=8/group), MHC-ATGL mice and wild-type mice with corresponded age and sex were included as control. Cardiac ATGL protein expression, serum levels of cardiac troponin T and cardiac kinase-MB (CK-MB), cardiac free fatty acid and reactive oxygen species were detected. The wild-type and MHC-ATGL burn groups were not only compared with their corresponded control groups, but also compared between each other. Results: The hair color and development were shown little difference between each group. ATGL protein expression is elevated in wild-type burn group (1.00±0.68 vs 3.09±0.93, P=0.023) and decreased in MHC-ATGL burn group (17.84±2.41 vs 10.36±2.22, P<0.001), while ATGL protein expression is still increased in MHC-ATGL burn group compared with wild-type burn group (P<0.001). Serum levels of cardiac troponin T and CK-MB were both elevated in wild-type burn group and MHC-ATGL burn group [(0.456±0.131) vs (0.076±0.019) μg/L and (0.219±0.089) vs (0.060±0.019) μg/L, (1 421±162) vs (221±67) U/L and (761±142) vs (221±41) U/L] (all P<0.001), while serum levels of cardiac troponin T and CK-MB was still decreased in MHC-ATGL burn group compared with wild-type burn group (P<0.001). In addition, cardiac free fatty acid was increased in wild-type burn group and little difference was found in MHC-ATGL burn group [(2.54±0.51) vs (0.46±0.27) mmol/L, P<0.001, and (0.81±0.38) vs (0.59±0.25) mmol/L, P=0.251], while cardiac free fatty acid was significant reduction in MHC-ATGL burn group compared with wild-type burn group (P<0.001). Levels of cardiac reactive oxygen species was both elevated in wild-type burn group and MHC-ATGL burn group [(1.89±0.23) vs (1.00±0.18) and (1.38±0.17) vs (0.95±0.13)] (both P<0.001), while levels of cardiac reactive oxygen was reduction in MHC-ATGL burn group compared with wild-type burn group (P<0.001). Conclusion: Cardiac ATGL overexpression may protect against burn-induced cardiac injury through reducing free fatty acid and reactive oxygen species production.

Abstract
Objective: To explore the mechanism of CD38-mediated cardiac damage under hypoxic-ischemic (H/I) conditions. Methods: Twenty CD38(-/-) male mice (8-week-old) and 20 wild-type (WT) male C57BL/6J mice (8-week-old) were randomly selected to construct the model of approximately 25% of the total body surface area (TBSA) burn injury. The cardiomyocytes (CMs) were separated from neonatal mice (1day) to construct the H/I injury model. Ad-CD38 adenovirus was transfected into CD38(-)/- primary CMs to callback CD38 expression. Animal experiments were grouped into WT-control group, CD38(-/-)-control group, WT-burn group, and CD38(-/-)-burn group (10 mice in each group). Primary CMs were divided into 6 groups: WT-normoxia group, CD38(-/-)-normoxia group, CD38(-/-)+Ad-CD38-normoxia group, WT-H/I group, CD38(-/-)-H/I group, CD38(-/-)+Ad-CD38-H/I group. The release of lactic dehydrogenase (LDH) from CMs and the cell viability were measured to estimate the level of myocardial injury. Ultrastructure of cardiomyocytes was examined by electron microscope. CD38 protein level and mitochondrial apoptosis-related proteins were detected by Western blot. Flow cytometry was used to detect mitochondrial reactive oxygen species (MitoSOX) of CMs under H/I condition. Cardiac function of mice was detected by ultrasonic apparatus. Results: (1) Animal experiments: The expression level of cardiac CD38 in WT-burn group was significantly higher than that in sham group (P<0.001). The heart function of CD38(-/-)-burn group was obviously better than WT-burn group [ejection fraction (EF)%: (84.70±2.31)% vs (76.10±2.96)%, shortening fraction (FS)%: (48.90±5.00)% vs (38.10±2.80)%] (both P<0.001). (2) Cell experiments: The expression level of cardiac CD38 in WT CMs under H/I condition was significantly higher than that in WT CMs under normoxia condition (P<0.05). The level of LDH, apoptotic cell and MitoSOX in CD38(-/-)-H/I group were fewer than WT-H/I group and CD38(-/-)+Ad-CD38(-)H/I group [(11.2±3.0)% vs (18.2±3.4)% and (17.6±4.0)%, (13.0±2.8)% vs (23.1±4.9)% and (23.3±6.0)%, (162±11)% vs (228±18)% and (220±18)%] (all P<0.001). The levels of cleaved-caspase3, Cytochrome-C in CD38(-/-)-H/I group were significantly lower than those in WT-H/I group and CD38(-/-)+Ad-CD38-H/I group (P<0.001). The cell viability in CD38(-/-)-H/I group was higher than that in WT-H/I group and CD38(-/-)+Ad-CD38-H/I group (0.355±0.043 vs 0.280±0.051 and 0.291±0.024) (all P<0.05). Electron microscopy results showed that structure of mitochondria in CD38(-/-)-H/I group was better than in WT-H/I group and CD38(-/-)+Ad-CD38-H/I group. Conclusion: Overexpression of CD38 contributes to cardiac damage by stimulating mitochondrial apoptotic pathway.

Abstract
Abstract Objective To study the differential metabolites of serum in rats dying from untypical electric injury by 1H nuclear magnetic resonance (1 NMR)-based metabolomics methods, in order to provide clues for identification of death from antemortem untypical electric injury and instant postmortem electric injury. Methods Models of rats dying from untypical electric injury, instant postmortem electric injury, mechanical asphyxia, mechanical injury, and high temperature injury were established. The rats in control group were executed without any treatment. The serums of rats from every group were detected by 1H NMR-based metabolomics technology to screen differential metabolites. Results The rats dying from untypical electric injury group was compared with those from mechanical asphyxia group, mechanical injury group, high temperature injury group, and control group, respectively. Four chemical shift points with diagnostic value, and their corresponding metabolites were screened. These chemical shift points contained many small molecules, such as alcohols, phenols, sugars, amino acids, etc. The death from untypical electric injury group was compared with those from instant postmortem electric injury group and control group, and then eight chemical shift points with diagnostic value and their corresponding metabolites were screened. These chemical shift points contained small molecules, such as sugars, amino acids, esters, nucleic acids, etc. Conclusion The 1H NMR-based metabolomics technology can identify differential metabolites of serum in rats dying from untypical electric injury, therefore it may provide a basis for the diagnosis of death from untypical electric injury and the identification of antemortem electric injury and instant postmortem electric injury.

Abstract
BACKGROUND Up to 15% of young adults with glioblastoma have the activating oncogenic BRAF V600E mutation, an actionable target of the MAPK signal transduction pathway governing tumor cell proliferation. Small molecule inhibitors of BRAF and MEK, a downstream protein immediately following BRAF, have been shown to confer a survival advantage for patients with BRAF V600E mutant advanced melanoma. We describe our experience using this combined target therapy for two patients with BRAFV600E mutant glioblastoma (GBM) as primary treatment due to extenuating clinical circumstances that prohibited the prescription of standard treatment. CASE PRESENTATION The two patients were both 22 years old on presentation. After the initial tumor resection, they both developed rapid deterioration in performance status within a few weeks due to leptomeningeal metastases. In view of the critical condition, BRAF and MEK inhibitors were prescribed as first line treatment. The two patients both achieved dramatic clinical response, which was parallel to the impressive radiological regression of the disease. Unfortunately, the duration of disease control was short as drug resistance developed rapidly. The two patients died 7 and 7.5 month after initial diagnosis of GBM. CONCLUSIONS Primary treatment with inhibitors of BRAF and MEK can lead to tumor regression for patients with BRAF V600E mutant glioblastoma. We therefore recommend that all young GBM patients should undergo BRAFV600E mutation testing, especially for those with unusual aggressive clinical course.

Abstract
Objective: To explore the preoperative evaluation of sentinel lymph node (SLN) biopsy using contrast-enhanced ultrasonography (CEUS) in early breast cancer patients and the involved disturbing factors. Methods: Eighty-three female early breast cancer patients who underwent concurrent surgery in the Affiliated Cancer Hospital of Zhengzhou University between January 2017 and May 2018 were enrolled. CEUS was used to seek SLN and determine lymph node metastasis after signature of preoperative informed consent. Rapid pathological examination was used to determine whether metastasis existed in SLN. The sensitivity, specificity, accuracy, the differences between CEUS and pathological results, and the involved disturbing factors were evaluated. Results: A total of 212 SLNs were detected by CEUS and SLN biopsy with an average of 2.6 SLNs detected per patient, including 39 SLNs with cancer metastasis (18.4%) and 173 SLNs without cancer metastasis (81.6%). Among the 83 patients, 29 patients were predicted SLN-positive preoperatively utilizing CEUS (including 21 cases with SLN pathological metastasis and 8 cases with non-metastasis), 54 patients were predicted SLN-negative (including 5 cases with SLN pathological metastasis and 49 cases with non-metastasis). The preoperative evaluation of SLN utilizing CEUS were performed with a sensitivity of 80.8% (21/26), specificity of 86.0% (49/57), positive predictive value of 72.4% (21/29), and negative predictive value of 90.7% (49/54), positive likelihood ratio of 5.75, negative likelihood ratio of 0.22, and the accuracy of 84.3% (70/83), respectively. The area under the ROC curve (AUC) was 0.834 (95% CI: 0.736-0.906). The primary tumor mean size of SLN-negative group predicted preoperatively utilizing CEUS was (1.78±0.14) cm, and that of the SLN positive group was (2.64±0.19) cm. The difference between the two groups was (0.86±0.24) cm with statistical significance (P=0.000 6). The SLN mean size of SLN-negative group (141 SLNs) was (1.41±0.05) cm and that of SLN-positive group (71 SLNs) was (1.69±0.07) cm. The difference between the two groups was (0.28±0.09) cm with statistical significance (P=0.002 8). Conclusions: Preoperative CEUS possesses the predictive value for SLN metastasis in early breast cancer. The predicted results may be influenced by the primary tumor size and the SLN size.

Abstract
The detection of circulating tumor cells (CTCs) from peripheral blood is considered as great significance for the diagnosis and prognosis of cancer patients. Raman spectroscopy is a highly sensitive optical detection technique that can provide fingerprint molecular identification information. In this paper, the silver film substrate surface-enhanced Raman scattering (SERS) was used to research several tumor cells, immortalized cells, clinical cancer cells isolated from cancer patient's tissue and blood cells. The results display that there is great difference for the nucleic acid characteristic peaks of those cells. The red blood cells have almost none nucleic acid characteristic peak and the SERS signals of white blood cells are only a slight increase. Except for immortalized cells and few tumor cells, the nucleic acid characteristic peaks of some tumor cells have huge enhancement. Nucleic acid characteristic peaks of clinical cancer cells also have greater enhancement. The discriminant model established by the intensity ratio of the nucleic acid characteristic peak 730 cm-1 to the substrate background peak 900 cm-1 shows that some tumor cells and clinical sample cells can be separated from white blood cells, but tumor cells with relatively low-DNA index cannot be differentiated from white blood cells. This study demonstrates that thin-film SERS technology can distinguish between blood cells and some types of tumor cells. This study opens up a new possible method for the detection of CTCs with label-free SERS spectra.

Abstract
INTRODUCTION Normal skull base structures are destroyed either by the skull base pathology itself or during surgery that results in cerebrospinal fluid (CSF) leak. Skull base repair is usually performed transnasally by using a nasal septal flap. But when NSF is not available and failed repeated transnasal repair, a cranionasal repair with frontal pericranial flap (PF) can be attempted to achieve the highest successful chance. We performed a dual layer/split PF repair of a skull base defect using cranionasal approach and here we describe the technique. CASE DESCRIPTION A 74-year-old man suffered from CSF leak and ventriculitis after multiple transnasal surgeries for pituitary macroadenoma despite multiple repairs with intranasal vascularized flaps. We performed repair by cranionasal approach and using frontal PF. The frontal PF was divided into left and right halves. The left half went intradural, through the chiasmatic window to reach the sella and cover the tubercular and sellar defect from above. The right half went through the nasion into the nose to cover the defect from below. So the defect was covered by two vascularized flap from a single frontal PF. The repair was successful with no CSF leak and infection successfully treated by antibiotics. CONCLUSION We introduced the cranionasal dual layer/split PF technique to repair anterior skull base and successfully stopped the CSF leak in a patient after multiple EEA surgeries. This technique should only be considered in specific difficult situation where usual repair by EEA is impossible.

Abstract
Objective: To evaluate the value of combined detection of negative costimulatory molecule B7-H4 and carcinoembryonic antigen (CEA) in diagnosing malignant and benign pleural effusion. Methods: Ninety-seven pleural effusion specimen were collected, 55 of which were diagnosed as malignant pleural effusion and 42 were benign pleural effusion. Enzyme-linked immunosorbent assay(ELISA) was used to examine the concentration of B7-H4 and CEA in pleural effusion. Electro-chemiluminescence immunoassay was used to detect the CEA level in pleural effusion. Receiver operating characteristic (ROC) curve was established to analyze and evaluate the single or combined detection of B7-H4 and CEA in diagnosing malignant and benign pleural effusion. Results: The concentrations of B7-H4 and CEA in malignant pleural effusion (MPE) group were (60.08±35.04) ng/ml and (41.49±37.16) ng/ml, respectively, obviously higher than (27.26±9.55) ng/ml and (2.41±0.94) ng/ml of benign pleural effusion (BPE) group (both P<0.01). Area under curve (AUC) of B7-H4 was 0.884 in MPE groupand the diagnostic sensitivity and specificity were 81.8% and 90.5%, respectively, at the optimized cut off value of 37.25 ng/ml. Likewise, area under curve (AUC) of CEA was 0.954 and the sensitivity and specificity were 87.3% and 95.2%, respectively, at the cut off value of 4.18 ng/ml. When B7-H4 >37.25 ng/ml or CEA>4.18 ng/ml, the sensitivity of diagnosis as MPE was down-regulated to 90.9% and the specificity was elevated to 88.1%. When B7-H4 >37.25 ng/ml and CEA>4.18 ng/ml, the sensitivity of diagnosis as MPE was down-regulated to 78.2% and the specificity was elevated to 97.6%. The sensitivity and specificity of combined detection of B7-H4 and CEA to diagnose MPE were elevated to 90.9% and 97.6%, respectively. The level of B7-H4 in MPE and BPE were both positively correlated with CEA (r=0.670, P=0.001 in MPE and r=0.002, P=0.001 in BEP). Conclusions: B7-H4 is a potential tumor marker in diagnosing the benign and malignant pleural effusion. Although the diagnostic value of B7-H4 may not precede to CEA, the combined detection of B7-H4 and CEA can improve the diagnostic sensitivity and specificity of MPE.

Abstract
Two-dimensional (2D) materials have been studied extensively as monolayers, vertical or lateral heterostructures. To achieve functionalization, monolayers are often patterned using soft lithography and selectively decorated with molecules. Here we demonstrate the growth of a family of 2D materials that are intrinsically patterned. We demonstrate that a monolayer of PtSe2 can be grown on a Pt substrate in the form of a triangular pattern of alternating 1T and 1H phases. Moreover, we show that, in a monolayer of CuSe grown on a Cu substrate, strain relaxation leads to periodic patterns of triangular nanopores with uniform size. Adsorption of different species at preferred pattern sites is also achieved, demonstrating that these materials can serve as templates for selective self-assembly of molecules or nanoclusters, as well as for the functionalization of the same substrate with two different species.

Abstract
INTRODUCTION The management of traumatic brain injuries in the elderly (age ≥ 65 years) is a constant dilemma. The aim of this study is to investigate for factors that may predict outcome of operative treatment in this group of patients. MATERIALS AND METHODS A retrospective analysis was conducted on 68 elderly patients who had been operated in a designated center from 2006 to 2010. Patients' age, Glasgow Coma score (GCS), pupillary responses, imaging findings, medical conditions, and the use of anticoagulant/antiplatelet agents on patient outcomes were studied. RESULTS The overall mortality rate was 55.9%. Older age, abnormal pupillary response, low GCS, the presence of midline shift and cistern obliteration on computerized tomography were associated with poor survival. Patient aged 75-84 with normal bilateral pupillary response still had an overall survival rate of 52.6% and good outcomes (Glasgow outcome score: 4 or 5) in 36.8% of patients. Abnormal pupillary response in at least one eye and preoperative GCS ≤ 12 were associated with very poor prognosis. CONCLUSIONS More advanced age was found to be associated with progressively worse outcome. A subgroup patients aged below 85 would survive and could achieve good clinical outcome. The prognosis of those aged over 85 with moderate or severe head injuries was extremely poor.

Abstract
Objective: This study was designed to investigate the prognostic implications of the intertumoral heterogeneity of molecular phenotype in multifocal and multicentric breast cancer (MMBC). Methods: The clinical and follow-up data of 146 patients with MMBC from Jan.2009 to Dec. 2009 treated in Tumor Hospital Affiliated to Zhengzhou University were retrospectively analyzed. We used Kaplan-Meier curves to compare the survivals of patients who had tumors with molecular phenotypic heterogeneity and patients who had multifocal homogeneous tumors in molecular phenotype, and the survivals of patients who had heterogeneous tumor type and grade and who had homogeneous tumor type and grade.The corresponding hazard ratio was calculated by Cox proportional-hazards regression. Results: Intertumoral heterogeneity in histological type and grade of multiple breast cancer was detected in 16 of 146 patients (11.0%) and in 10 of 146 patients (6.8%), respectively. Interfocal heterogeneous molecular phenotype of multiple breast cancer was detected in 24 of 146 patients (16.4%). There was no significant difference in 5-year disease-free survival in multifocal cancer patients who had heterogeneous histological type and grade and who had homogeneous type and grade tumors (75.0% vs. 77.3%, P=0.808). Multifocal cancers patients who had heterogeneous tumorsin molecular phenotype compared with those with homogeneous tumors in molecular phenotype had worse 5-year disease-specific survival (78.7% vs. 58.3%, P=0.037), and had a greater risk of recurrence (HR=2.130, 95%CI=1.027-4.420; P=0.042). Phenotyping the additional cancer foci influenced the therapeutic decision in up to 16 patients(11.0%). Conclusions: Multifocal breast cancer patients who had heterogeneous tumors in molecular phenotype have a statistically significantly shorter disease-free survival. Phenotyping the additional cancer foci and managing with proper therapeutic decision may reduce the risk of recurrence or metastasis, and improve the outcomes of the patients.

Abstract
Intervertebral disc degeneration is the main cause of lumbago disease, in which the extracellular matrix structure and moisture in the nucleus pulposus is lost continuously. In this study, we aimed to detect differential expression of silence mating type information regulation 2 homolog 1 (SIRT1) and matrix metalloproteinase-1 (MMP-1) in human intervertebral disc nucleus pulposus cells and to explore the effects of SIRT1 and MMP-1 on the development of the intervertebral disc degeneration. Intervertebral disc nucleus pulposus specimens from 41 patients who underwent lumbar protrusion resection at HuiZhou Municipal Central Hospital, during the period from October 2011 to December 2013, were studied in comparison with 23 control cases from patients who underwent fractured lumbar resection. In degenerated human intervertebral disc nucleus pulposus cells, the expression of SIRT1 is decreased and MMP-1 is increased compared with that of the control cells. Resveratrol could reverse these effects, thereby increasing the expression of SIRT1 (0.87 ± 0.07 vs 0.54 ± 0.04), Coll2α1 (0.90 ± 0.08 vs 0.38 ± 0.01), and aggrecan (0.69 ± 0.07 vs 0.42 ± 0.05) and decreasing the expression of MMP-1 (0.61 ± 0.03 vs 0.93 ± 0.08). These results suggest that resveratrol could possibly reverse the process of intervertebral disc degeneration and thus could be applied as a potential drug for the disease.

Abstract
This study investigated Zn-bearing zeolite clinoptilolite (Zn-ZCP) as a Zn supplement on performance, organ or tissue development, Zn accumulation in tissues, and gene expression of Zn transporters in the duodenum of broilers. A total of 300 1-d-old Arbor Acres chickens were randomly allocated to 5 dietary treatments with 6 replicate cages of 10 birds per treatment for a 21-d feeding period. The treatments comprised a basal corn–soybean meal diet without supplemental Zn (the control) or similar diets supplemented with 80 mg/kg Zn from ZnSO4 or 20, 40, or 80 mg/kg Zn from Zn- ZCP, respectively. Supplementation of Zn-ZCP had a positive effect on G:F (linear, P < 0.05) and had tendency difference on ADG (linear, P < 0.1) of broilers during 1 to 21 d. Incremental Zn-ZCP inclusion in the diet increased the fresh weight of the pancreas (linear, P < 0.05) and tibia (linear, P < 0.05) in broilers on d 14. The same trend to the fresh weight of the tibia (linear, P < 0.05) and pancreas (linear, P < 0.05) was observed on d 21. Increasing Zn-ZCP level showed a linear response on Zn concentration in the liver (linear, P < 0.001), pancreas (linear, P < 0.05), and tibia (linear, P < 0.05) on d 14. The same trend of Zn concentrations in pancreas (linear, P < 0.05) and tibia (linear, P < 0.001) was observed on d 21. The mRNA levels of Zn transporter 2 (ZnT-2) and Zn transporter 5 (ZnT-5) in the duodenum of chicks fed the diet with 80 mg/kg Zn from Zn-ZCP did not differ from those of chicks fed the control diet, but both were lower (P < 0.05) than those of chicks fed ZnSO4 diet. Metallothionein (MT) mRNA levels of broilers fed the diet supplemented with 80 mg/kg Zn from Zn-ZCP or ZnSO4 was higher (P < 0.05) than that in the control group. Dietary treatments did not affect the mRNA expression of Zn transporter 1 (ZnT-1) or metal response element-binding transcription factor-1 (MTF-1). In conclusion, as a Zn supplement, Zn-ZCP was comparable to ZnSO4 for enhancing Zn accumulation and growth performance of broilers during 1 to 21 d. Broilers fed the diet with 80 mg/kg Zn from Zn-ZCP had different expressions of ZnT-2 and ZnT-5 in the duodenum compared with those fed the ZnSO4 diet.

Abstract
Cigarette smoking is an important risk factor for gastrointestinal (GI) disorders, including peptic ulcers, inflammatory bowel diseases, such as Crohn's disease and cancer. In this review, the relationship between smoking and GI disorders and the underlying mechanisms are discussed. It has been demonstrated that cigarette smoking is positively associated with the pathogenesis of peptic ulcers and the delay of ulcer healing. Mechanistic studies have shown that cigarette smoke and its active ingredients can cause mucosal cell death, inhibit cell renewal, decrease blood flow in the GI mucosa and interfere with the mucosal immune system. Cigarette smoking is also an independent risk factor for various types of cancer of the GI tract. In this review, we also summarize the mechanisms through which cigarette smoking induces tumorigenesis and promotes the development of cancer in various sections of the GI tract. These mechanisms include the activation of nicotinic acetylcholine receptors, the formation of DNA adducts, the stimulation of tumor angiogenesis and the modulation of immune responses in the GI mucosa. A full understanding of these pathogenic mechanisms may help us to develop more effective therapies for GI disorders in the future.

Abstract
Synchrotron radiation-based X-ray absorption near edge structure (XANES) was introduced to directly analysis chemical species of arsenic (As) in the cells of Trichoderma asperellum SM-12F1, Penicillium janthinellum SM-12F4, and Fusarium oxysporum CZ-8F1 capable of As accumulation and volatilisation. After exposure to As(V) of 500 mg L(-1) for 15 days, a total of 60.5% and 65.3% of the accumulated As in the cells of T. asperellum SM-12F1 and P. janthinellum SM-12F4, respectively, was As(III), followed by 31.3% and 32.4% DMA (dimethylarsinic acid), 8.3% and 2.3% MMA (monomethylarsonic acid), respectively. However, for F. oxysporum CZ-8F1, 54.5% of the accumulated As was As(III), followed by 37.8% MMA and 7.7% As(V). The reduction and methylation of As(V) formed As(III), MMA, and DMA as the primacy products, and the reduction of As(V) might be more easily processed than the methylation. These results will help to understanding the mechanisms of As detoxification and its future application in bioremediation.

Abstract
In order to develop an effective strategy of breast cancer therapy targeting survivin and its splice variants survivin-ΔEx3 and survivin-2B, the present study constructed four expression vectors by fusing the survivin antisense gene, the survivin (T34A) gene, the survivin-ΔEx3 antisense gene, and the survivin-2B gene with the enhanced green fluorescent protein (eGFP) gene. Each of these vectors was transiently transfected into the B-Cap-37 human breast cancer cell line. The effects of these four vectors with diverse genes on the proliferation and apoptosis of B-Cap-37 breast cancer cells were examined and compared in vitro using MTT and flow cytometry assays. Results of the MTT assay indicated that all four gene therapy plasmids were most effective at inhibiting the proliferation of B-Cap-37 cells 72 h after transfection. However, the four gene therapies had different rates of cell inhibition. pcDNA3.1(+)-egfp-anti-survivin and pcDNA3.1(+)-survivin (T34A)-egfp had almost equivalent or better effectiveness at suppressing cell growth. pcDNA3.1(+)-egfp-anti-survivin-ΔEx3 moderately inhibited the growth of B-Cap-37 cells. In contrast, pcDNA3.1(+)-survivin-2B-egfp had limited inhibition of cell growth. Similar profile of effectiveness of four gene therapies in soliciting cell apoptosis was also observed. These results suggest the relative importance of targeting survivin and its splice variant survivin-ΔEx3 in breast cancer treatment.

Abstract
We report a 26-year-old man with 6 years, history of duodenal gastrointestinal stromal tumor (GIST) with liver, peritoneum and lung metastases. He presented with left eye ptosis, diplopia, left facial numbness and a left temporal fossa mass that was confirmed to be GIST with left skull and left orbit metastases. Craniectomy with cranioplasty, tumor excision and decompression were performed. There was an improvement of his visual symptoms and facial numbness. To our knowledge, this is one of the few reports of surgical management of GIST, metastasized to skull and orbit, with good symptomatic relief.

Abstract
Li, Lan-Fun (Western Reserve University School of Medicine, Cleveland, Ohio), Lars Ljungdahl, and Harland G. Wood. Properties of nicotinamide adenine dinucleotide phosphate-dependent formate dehydrogenase from Clostridium thermoaceticum. J. Bacteriol. 92: 405-412. 1966.-A nicotinamide adenine dinucleotide phosphate (NADP)-dependent formate dehydrogenase has been isolated from C. thermoaceticum. The enzyme is very sensitive to oxygen and requires sulfhydryl compounds for activity. The apparent K(m) at 50 C and pH 7.0 for NADP is 5.9 x 10(-5)m and for formate, 2.2 x 10(-4)m. The enzyme is most active at about 60 C and at pH values between 7.0 and 9.0. The enzyme catalyzes an exchange between C(14)O(2) and formate, which requires NADP, but net synthesis of formate from CO(2) and reduced nicotinamide adenine dinucleotide phosphate could not be demonstrated. The reaction does not involve ferredoxin.
