Abstract
This study aimed to examine whether awareness of cancer diagnosis and prognosis among patients with stage IV lung cancer treated with first-line erlotinib vary with psychological distress and quality of life (QoL). This study was carried out at the Comprehensive treatment Department of Tianjin Cancer Hospital between August 2013 and September 2015 among patients ≥18 years-old and suffering from EGFR mutation-positive stage IV non-small cell lung cancer (NSCLC) treated with first-line erlotinib (150 mg/day; N = 137). The Hospital Anxiety and Depression Scale (HADS) was administered before (baseline) and after 12 weeks of treatment. QoL was assessed using the Functional Assessment of Cancer Therapy-Lung (FACT-L) questionnaire. Diagnosis and prognosis awareness was assessed by interview. Among patients, 21% reported to be fully aware of their disease; 41% were only aware of the diagnosis, not the stage; and 51% were not aware at all. Among patients, 63.5% reported elevated anxiety, 71.5% were depressed, and 75.2% had HADS score ≥15 (emotional distress). Patients who were totally and partly aware experienced improvements in HADS and FACT-L compared with baseline (all p < .05). Patients who were not aware scored better than the other patients for all FACT-L subscales from baseline to 12 weeks (all p < .05). Aware patients experienced improvements from baseline in HADS and FACT-L (all p < .05). Awareness of cancer diagnosis and stage was associated with initially high global distress and poorer QoL. Unaware patients exhibited better emotional distress and QoL during first-line therapy with erlotinib for EGFR mutation-positive advanced NSCLC.

Abstract
OBJECTIVE To identify the sensitive scales and the early change of nerve conduction for chronic oxaliplatin-induced peripheral neuropathy (OXLIPN), and to investigate correlation between the symptoms of acute OXLIPN and chronic OXLIPN. METHODS Between December 2014 and August 2015, 16 colorectal cancer patients confirmed by pathology, from department of Oncology, Chinese PLA General Hospital, scheduled to receive XELOX, completed the acute neurotoxic symptoms questionnaire at the end of 1 cycles and the scales of TNSc and NCI-CTC at the baseline and the end of 4 cycles. Nerve conduction studies (bilateral peroneal nerves and sural nerves) were performed in 11 patients at the baseline and the end of 4 cycles. RESULTS After chemotherapy, TNSc increased 1-9 points for all cases, while NCI-CTC increased 1 point for only 9 cases, the remaining 7 cases had the same NCI-CTC score before and after chemotherapy, where TNSc increased 1-6 points. Left sural nerve a-SNAP (amplitude of sensory nerve action potential) was (15.3±5.8)μV before chemotherapy and(12.3±5.0)μV after chemotherapy. Right sural nerve a-SNAP was (17.4±8.6)μV before chemotherapy and (13.3±6.7)μV after chemotherapy. After chemotherapy, these datum were significantly reduced for left peroneal nerve distal and proximal a-CMAP (amplitude of compound muscle action potential), bilateral sural nerve a-SNAP and left sural nerve SCV (sensory conduction velocity) (P<0.05). After chemotherapy, TNSc was correlated significantly with the acute neurotoxic symptoms questionnaire (Spearman r=0.698, P=0.003). CONCLUSIONS TNSc is more sensitive to the severity and changes in chronic OXLIPN than NCI-CTC. Sural nerve a-SNAP has a higher sensitivity for the early changes of nerve conduction studies in chronic OXLIPN. Patients who have more symptoms of acute OXLIPN are those who eventually develop more severe chronic OXLIPN.

Abstract
OBJECTIVE To compare the proliferation and osteoblastic differentiation of dental pulp stem cell (DPSC) isolated from normal and inflamed pulps of different degrees in Beagle immature premolars, and provide evidence for the use of inflammatory DPSC (IDPSC). METHODS This study evaluated 14 Beagle's young premolars (21 roots). In the experiment group, irreversible pulpitis was induced by pulp exposure and the inflamed pulps were extracted 2 weeks and 6 weeks after the pulp chamber opening.For the control group, normal pulps were extracted immediately after the exposure. HE staining and real-time PCR were performed to confirm the inflammation. The cells were isolated from the inflamed and normal pulps (IDPSC and DPSC). Cell proliferation and osteoblastic differentiation potentials of the two cells were compared. RESULTS Inflammation cells infiltration was observed in the inflamed pulps by HE staining. The expression of inflammatory factor was much higher in the 6 week inflamed pulp. IDPSC had higher potential of cell proliferation and osteoblastic differentiation potentials. Furthermore, the osteoblastic differentiation potentials of IDPSC from 2 week inflamed pulp were higher than those from 6 week inflamed pulp. CONCLUSION The potential of cell proliferation and osteoblastic differentiation of DPSC was enhanced at early stage of irreversible pulpitis, and reduced at late stage in Beagle immature premolars.

Abstract
Objective: To analyze the features of nerve conduction in patients with amyotrophic lateral sclerosis (ALS), and explore the correlation between compound muscle action potential (CMAP) amplitude and disease duration and revised amyotrophic lateral sclerosis functional rating scale (ALSFRS-R). Methods: Standard motor and sensory nerve conduction studies were performed in 154 patients with ALS. The following parameters were collected including CMAP amplitude, distal motor latency (DML), motor conduction velocity, sensory conduction velocity and sensory nerve action potential amplitude. Regression study was done to explore the correlation between CMAP amplitude and disease duration and ALSFRS-R. Results: Motor nerve conduction abnormalities were presented in a majority of the patients with prolonged DML in the tibial nerve, median nerve and ulnar nerve as the most common form (61.06%-81.42%), followed by decreased CMAP amplitude (30.12%-53.98%), decreased MCV (12.05%-16.81%) and absence of CMAP (2.65%-9.73%). Sensory nerve conduction abnormalities were detected in a small proportion of patients and the decreased SCV, decreased SNAP amplitude and absence of SNAP in the sural nerve, median nerve and ulnar nerve were found in 1.22%-2.73%, 0-1.82% and 0-1.22% patients respectively. No correlation was found between CMAP of the common peroneal nerve, tibial nerve, median nerve and ulnar nerve and the disease duration (P>0.05), while significant positive correlation was established between CMAP amplitude of the median nerve and ulnar nerve and ALSFRS-R (r=0.273, P=0.016; r=0.357, P=0.001). Conclusions: Motor nerve conduction is abnormal in a majority of ALS patients with prolonged DML as the most common form, while abnormal sensory nerve conduction is only found in a few of ALS patients. CMAP amplitude of the median nerve and ulnar nerve might be of certain clinical value in evaluating the severity of ALS.

Abstract
Objective: To analyze the features of needle electromyography (EMG) in patients with amyotrophic lateral sclerosis (ALS), and explore the correlation between EMG parameters of the tenth thoracic paraspinal muscle and disease duration, rate of disease progression, forced vital capacity (FVC) and revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R). Methods: Standard EMG was recorded from unilateral sternocleidomastoid muscle and/or tongue muscles, upper and lower limbs muscles and the tenth thoracic paraspinal muscle in 112 patients with definite ALS between March 2012 and June 2013 in the Department of Neurology at Chinese PLA General Hospital. Parameters studies included spontaneous potentials, duration and amplitude of motor unit potentials (MUP), pattern of recruitment. Results: EMG revealed diffuse neurogenic changes in each case. Fibrillation potential or positive sharp waves were found in some muscles in all of patients, and both of them were found in most of the cases. Fasciculation potentials (FPs) were found in 8 patients and accompanied with fibrillation potential and positive sharp waves in 5 of them. Complex repetitive discharges (CRDs) were found in only 1 patient. Duration and amplitude of MUP was prolonged and increased in ALS patients, and the rate of high amplitude and decreased recruitment pattern were 35.71% and 72.32%, respectively. Logistic regression analysis revealed an association of the FVC loss with the drop of ALSFRS-R and peak amplitude of the tenth thoracic paraspinal muscle. Conclusions: The abnormal spontaneous activity with high frequency are fibrillation potentials and/or positive sharp waves. However, FPs is observed in a small number of patients and CRDs is rarely seen in ALS. The ALSFRS-R and peak amplitude of thetenth thoracic paraspinal muscle may be of certain clinical value in estimating the severity of disease especially the respiratory dysfunction in ALS patients.

Abstract
Mutations in the mitochondrial genome have been found to be associated with essential hypertension. Here, we report the clinical and molecular characterization of a three-generation Han Chinese family with maternally inherited hypertension. Most strikingly, this pedigree exhibited a high penetrance of hypertension. Sequence analysis of the mitochondrial genome showed the presence of a homoplasmic T16189C mutation in the D-loop and the intergenic CO2/tRNA(Lys) 9-bp common deletion, as well as a set of polymorphisms belonging to the East Asia haplogroup B5b1. The well-known T16189C mutation, which is in the first hypervariable segment of the mitochondrial control region, is implicated to be associated with a wide range of clinical disorders. Moreover, the genetic polymorphism 9-bp common deletion is found to be associated with hepatocellular carcinoma in the Han Chinese population. Thus, the combination of T16189C mutation and the 9-bp deletion may have caused mitochondrial dysfunction and contributed to the development of essential hypertension in this Chinese family.

Abstract
OBJECTIVE To investigate the differences of the B-type natriuretic peptide (BNP) levels in serum or plasma of the STEMI patients with different infarction sites. To explore the relationship between the BNP level and the short-term prognosis in patients with ST-segment elevation myocardial infarction (STEMI). PATIENTS AND METHODS A total of 216 STEMI patients were enrolled in this study from June 2012 to June 2014. All patients received coronary angiography (CAG). Based on electrocardiography (ECG) and CAG results, patients were divided into three groups. Group A included 80 patients with anterior/lateral wall myocardial infarction, group B included 76 patients with inferior/posterior wall myocardial infarction and group C included 60 patients with right ventricular myocardial infarction. We enrolled 53 patients with normal CAG results as Group D. BNP levels were compared among these groups. and according to BNP levels, all patients were subdivided into normal BNP group (< 100 ng/mL, n = 53), mild-higher BNP group (100-400 ng/mL, n = 105) and marked-higher BNP group (≥ 400 ng/mL, n = 58). The occurrence of major adverse cardiovascular events (MACE) including secondary heart failure, severe arrhythmia, post-infarction angina, recurrent myocardial infarction, and cardiac death within 6 months after disease onset were assessed. RESULTS BNP levels showed a gradually decreasing trend in groups A, B, C and D (p < 0.05). Significant differences in left ventricular ejection fraction (LVEF) were found among normal BNP group, mild-high BNP group and marked-higher BNP group (p < 0.05). The MACE occurrence presented no statistical differences between normal BNP group and mild-higher BNP group (p > 0.05). The MACE prevalence in marked-higher BNP group was significantly higher than normal BNP group and mild-higher BNP group (p < 0.05). CONCLUSIONS BNP levels can be used as a clinical indicator to predict short-term prognosis in STEMI patients.

Abstract
OBJECTIVES As one of the most vulnerable populations in China, many migrants work in the small-to-medium-sized enterprises (SMEs). This study aims to describe the self-reported illnesses and service utilization of the migrants working in the SMEs in Pearl River Delta Areas (PRDA) of Guangdong province, China. STUDY DESIGN Cross-sectional survey. METHODS We interviewed 856 migrants working in the SMEs of different manufacturing industries in 2012. Descriptive analysis was employed to report self-reported illnesses and service utilisation among migrants in the last two weeks and in the last year. Statistical tests such as χ2 test were used to explore factors influencing their service utilisation. RESULTS In the last two weeks, 91(11%) of the respondents reported having any illness. The most reported illness was respiratory problem (69%), while 9.9%, 7.7% and 13% reported having digestive, skin and other problems respectively. The most important symptom was cough (39%). Thirty-seven percent of the respondents who reported any illness had visited health facilities. The lower income group were more likely to visit health facilities than the higher income group (P = 0.006). The most reported reason for not visiting health facilities was 'feeling not serious' (65%). In the last year, 13% reported having respiratory problems and 7.8% reported accidental injuries. Less than 3% received hospitalization care. The proportion of those without hospitalization to those who should have been hospitalized was 31%. CONCLUSION Underuse of the health service among migrants working in the SMEs could be associated with the 'healthy migrant' effect. However, when assessed among the ill migrants in the SMEs, the utilisation rate was still low mainly due to their poor health awareness. Improving their risk perception and integration of occupational and general health service is crucial to improve the health conditions and utilisation of service among migrants in the SMES.

Abstract
The aim of our study was to systematically review studies which had compared self-concept in left-behind children with the general population of children in China. Relevant studies about self-concept of left-behind children in China published from 2004 to 2014 were sought by searching online databases including Chinese Biological Medicine Database (CBM), Chinese National Knowledge Infrastructure (CNKI), Wanfang Database, Vip Database, PubMed Database, Google Scholar and Web of Science. The methodological quality of the articles was assessed by using Newcastle-Ottawa Scale (NOS). Poled effect size and associated 95% confidence interval (CI) were calculated using the random effects model. Cochrane's Q was used to test for heterogeneity and I(2) index was used to determine the degree of heterogeneity. Nineteen studies involving 7758 left-behind children met the inclusion criteria and 15 studies were included in a meta-analysis. The results indicated that left-behind group had a lower score of self-concept and more psychological problems than the control group. The factors associated with self-concept in left-behind children were gender, age, grade and the relationships with parents, guardians and teachers. Left-behind children had lower self-concept and more mental health problems compared with the general population of children. The development of self-concept may be an important channel for promoting mental health of left-behind children.

Abstract
Sex-specific regulatory elements are key components for developing insect genetic sexing systems. The current insect genetic sexing system mainly uses a female-specific modification system whereas little success was reported on male-specific genetic modification. In the silkworm Bombyx mori, a lepidopteran model insect with economic importance, a transgene-based, female-specific lethality system has been established based on sex-specific alternative splicing factors and a female-specific promoter BmVgp (vitellogenin promoter) has been identified. However, no male-specific regulatory elements have yet been identified. Here we report the transgenic identification of two promoters that drive reporter gene expression in a testis-specific manner in B. mori. Putative promoter sequences from the B. mori Radial spoke head 1 gene (BmR1) and beta-tubulin 4 gene (Bmβ4) were introduced using piggybac-based germline transformation. In transgenic silkworms, expression of the reporter gene enhanced green fluorescent protein (EGFP) directed by either BmR1 promoter (BmR1p) or Bmβ4p showed precisely testis-specific manners from the larval to adult stage. Furthermore, EGFP expression of these two transgenic lines showed different localization in the testis, indicating that BmR1p or Bmβ4p might be used as distinct regulatory elements in directing testis-specific gene expression. Identification of these testis-specific promoters not only contributes to a better understanding of testis-specific gene function in insects, but also has potential applications in sterile insect techniques for pest management.
