ABSTRACT
OBJECTIVES@#To study the role of the low-density lipoprotein receptor-related protein 1 (LRP1)-proline-rich tyrosine kinase 2 phosphorylation (pPyk2)-matrix metalloproteinases 9 (MMP9) pathway in hyperoxia-induced lung injury in neonatal rats.@*METHODS@#A total of 16 neonatal rats were randomly placed in chambers containing room air (air group) or 95% medical oxygen (hyperoxia group) immediately after birth, with 8 rats in each group. All of the rats were sacrificed on day 8 of life. Hematoxylin and eosin staining was used to observe the pathological changes of lung tissue. ELISA was used to measure the levels of soluble LRP1 (sLRP1) and MMP9 in serum and bronchoalveolar lavage fluid (BALF). Western blot was used to measure the protein expression levels of LRP1, MMP9, Pyk2, and pPyk2 in lung tissue. RT-PCR was used to measure the mRNA expression levels of LRP1 and MMP9 in lung tissue.@*RESULTS@#The hyperoxia group had significantly higher levels of sLRP1 and MMP9 in serum and BALF than the air group (@*CONCLUSIONS@#The activation of the LRP1-pPyk2-MMP9 pathway is enhanced in hyperoxia-induced lung injury in neonatal rats, which may be involved in the pathogenesis of bronchopulmonary dysplasia.

ABSTRACT
Objective To understand the epidemic trend of schistosomiasis in China from 2010 to 2017 so as to provide the scientific evidence for schistosomiasis elimination. Methods The information of schistosomiasis control nationwide from 2010 to 2017 was collected, including the endemic of population, status of livestock control, and Oncomelania hupensis snail control. Microsoft Excel was applied for datum management and analysis. Results From 2010 to 2017, the epidemic of schistosomiasis in China dropped significantly. The decreasing amplitude of estimated number of patients nationwide was 88.46%. Seventy-one acute schistosomiasis patients were reported and 12.68% (9/71) of them were imported. The decreasing rate of cultivated cattle was 50.09%, and the accumulative number of schistosome-infected cattle was 17 239, and the average positive rate of stool examinations decreased from 1.04% to 0.000 22%. The area with snails nationwide was 373 596.18 to 363 068.95 hm2, and the new detected area with snails was 46.71 to 1 346.73 hm2. The area with schistosome-infected snails was 171.68 hm2 in 2012 and it was 9.25 hm2 in 2013. In 72 key monitoring points of 7 endemic provinces, there were 17 schistosome positive points of water body in 2010 and 6 points in 2016. There were some high risk-factors related to schistosomiasis transmission including schisto-some-infected cattle, dogs, and field rats, and the field stools, and the pasture in the area with snails in schistosomiasis monitoring points. Conclusions The endemic status of schistosomiasis in China has dropped significantly, and the transmission level is very low. However, the infectious source and risk factors in the endemic environments have not be eliminated. Therefore, the infectious source control, health education, snail control, and transmission monitoring should be strengthened, so as to promote the progress of schistosomiasis elimination.

ABSTRACT
OBJECTIVE@#To investigate whether craving and demographic factors to predict relapse in alcohol dependence.@*METHODS@#This study was a prospective cohort study. From August 2017 to August 2018, 158 Han male inpatients who met the diagnositic and statistical manual disorders-fourth version(DSM-IV) alcohol dependence diagnostic criteria were recruited from three mental hospitals in China. The participants were interviewed at baseline and followed up by telephone after 3 months for assessment. The baseline assessment after the acute withdrawal period included demographic data and alcohol-related data, clinical institute withdrawal assessment-advanced revised (CIWA-Ar), withdrawal and cue-induced craving on visual analog scale (VAS), Michigan alcoholism screening test (MAST), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and alcohol urge questionnaire (AUQ). According to the follow-up results, "relapse" was defined as the consumption of beverages containing ethanol at any time during the follow-up study, and "time to relapse" was defined as the number of days from the first drinking to the baseline. Whether relapse occurred and the time to relapse were the primary endpoints. Cox proportional hazard regression model was used to analyze the factors affecting the relapse of alcohol dependence.@*RESULTS@#In the study, 158 alcohol dependence patients were finally included, age from 21 to 60 years, with the mean age of (40.31±9.14) years. The relapse rate was 63.7% three months after baseline assessment. According to Cox univariate analysis and multivariate analysis, the age (OR=0.975, P=0.030) and CIWA-Ar scores (OR=1.126, P=0.010) significantly predicted relapse. And there was no significant difference in education level, marital status, withdrawal and cue-induced craving on VAS, SAS and SDS between the relapse group and the non-relapse group (P>0.05).@*CONCLUSION@#Age and severity of alcohol-dependent withdrawal symptoms during hospitalization are significantly related to relapse for alcohol in alcohol-dependent patients. To be exact, the older age is a protective factor, that is to say, the younger patients are prone to relapse, while the risk of relapse is raised by the higher severity of withdrawal symptoms. However, neither cue-induced nor withdrawal craving can predict relapse of alcohol-dependent patients.

Background@#Intravenous (IV) oxycodone has been used at induction to prevent an intubation reaction. The aims of the current study were to calculate the median effective dose (ED) and the 95% effective dose (ED) of an IV bolus of oxycodone that blunts the hemodynamic response to tracheal intubation with propofol according to gender and to observe the adverse events of induction-dose oxycodone.@*Methods@#Adult patients who required general anesthesia and tracheal intubation were enrolled. Tracheal intubation was performed using unified TD-C-IV video laryngoscopy and an ordinary common endotracheal tube. Dixon's up-and-down method was used to obtain EDdata for women and men separately. The initial dose of oxycodone was 0.2 mg/kg for women and 0.3 mg/kg for men (step size was 0.01 mg/kg). Next, a dose-response curve from the probit analysis was generated to determine the EDand EDto blunt the intubation reaction in female and male patients. Adverse events following oxycodone injection were observed for 5 min before propofol injection.@*Results@#Sixty-three patients were analyzed, including 29 females and 34 males. According to the probit analysis, the ED and EDof oxycodone required to blunt the intubation reaction in women were 0.254 mg/kg (95% confidence interval [CI], 0.220-0.328 mg/kg) and 0.357 mg/kg (95% CI, 0.297-2.563 mg/kg), respectively. In men, the ED and EDwere 0.324 mg/kg (95% CI, 0.274-0.381 mg/kg) and 0.454 mg/kg (95% CI, 0.384-2.862 mg/kg), respectively. Men required 28% more oxycodone than women for induction (P < 0.01). The most common adverse events were dizziness (87.3%), vertigo (66.7%), sedation (74.6%), and respiratory depression (66.7%).@*Conclusions@#Oxycodone can be used for induction to prevent intubation reactions. Gender affected the EDand EDof oxycodone for blunting the tracheal intubation reaction.

<p><b>OBJECTIVE</b>To investigate the expression of long non-coding RNA NANCI in lung tissues of neonatal mice with hyperoxia-induced lung injury and its regulatory effect on NKX2.1.</p><p><b>METHODS</b>A total of 48 neonatal C57BL/6J mice were randomly divided into an air group and a hyperoxia group, with 24 mice in each group. Each group was further divided into 7-day, 14-day, and 21-day subgroups, with 8 mice in each subgroup. The mice in the air group were fed in the indoor environment (FiO=21%) and those in the hyperoxia group were fed in a high-oxygen box (oxygen concentration: >95%). The mice were sacrificed at each time point and lung tissue samples were collected. Hematoxylin and eosin staining was used to observe pathological changes in lung tissues. RT-qPCR and Western blot were used to measure the mRNA and protein expression of NANCI and NKX2.1.</p><p><b>RESULTS</b>The air group had the highest mRNA expression of NANCI and NKX2.1 at 7 days and the same level of mRNA expression at 14 and 21 days. Compared with the air group, the hyperoxia group had significant reductions in the degree of alveolarization and radial alveolar count (RAC) in lung tissues (P<0.05), and in the hyperoxia group, RAC gradually decreased over the time of hyperoxia exposure (P<0.05). The hyperoxia group had significantly lower mRNA and protein expression of NANCI and NKX2.1 than the air group at all time points (P<0.05). In both groups, the relative mRNA and protein expression of NANCI and NKX2.1 gradually decreased over the time of hyperoxia exposure (P<0.05). The expression of NKX2 was positively correlated with that of NANCI (r=0.585, P=0.003), and the expression of NKX2 and NANCI was positively correlated with RAC in the hyperoxia group (r=0.655 and 0.541 respectively, P<0.05).</p><p><b>CONCLUSIONS</b>NANCI may be involved in the development of immature lung tissues. Lung injury is gradually aggravated over the time of hyperoxia exposure. The levels of NANCI and NKX2.1 are associated with the severity of lung injury, suggesting that the NANCI/NKX2.1 target gene signaling pathway might be involved in the development of hyperoxia-induced lung injury in neonatal mice.</p>

Objective To explore the impact of total parathyroidectomy(tPTX)on carotid-femoral pulse wave velocity(cfPWV)in hemodialysis patients. Methods A total of 35 patients undergoing hemodialysis with refractory secondary hyperparathyroidism and treated with tPTX were studied. Before tPTX and 1 year after the oper-ation,cfPWVwas measured and hepatic and renal function,serum calcium,serum phosphorus,intact parathyroid hormone and hemoglobin were measured. The impact of tPTX on cfPWV in hemodialysis patients was analyzed. Results Serum calcium,serum phosphorus and intact parathyroid hormone decreased(P < 0.01),while hemo-globin and serum albumin increased(P < 0.01)and cfPWV decreased 1 year after the operation,which showed statistical significance(P<0.01). The cfPWV of the patients with tPTX was still higher than that of healthy indi-viduals(P<0.01). Conclusion tPTX can effectively reduce cfPWV in hemodialysis patients with refractory sec-ondary hyperparathyroidism.
ABSTRACT
BACKGROUND:Studies have shown that tumor stem ceils are the basis and the main cause of tumor recurrence and chemotherapy failure.Therefore,the research on the drug resistance of tumor stem cells has become a hotspot in the field of stem cell research.OBJECTIVE:To analyze the biological characteristics of side population (SP) cells in the U266 cell lines in relation to drug resistance.METHODS:Flow cytometry was used to monitor the percentage of SP cells in the U266 cell lines.Fluorescence-activated cell sorter (FACS) analysis was used to isolate SP and non-SP (NSP) cells from the U266 cell lines.Further analyses of the cell cycle,multidrug resistant protein,methyl cellulose cloning assay of SP cells and NSP cells were performed.Real-time quantitative PCR was used to determine the expression of ABCG2 and MDR1 genes.RESULTS AND CONCLUSION:There were (2.46±0.35)％ SP cells in U266 cells,which were most in the G0 phase.The ratio of G0/G1 in SP cells was (81.50±5.42)％,which was significantly higher than that in NSP cells [(39.85±3.21)％;P ＜0.05].The positive expression rates of P-gp and ABCG2 in SP cells were signficantly higher than those in NSP cells (P ＜0.05).The cloning efficiency of SP cells was significantly higher than that of NSP cells (P ＜ 0.05).The mRNA expression of ABCG2 and MDR1 was also significantly higher in SP cells than in NSP cells (P ＜ 0.05).To conclude,a small subpopulation of the isolates of U266 cell lines belong to tumor stem cell-like SP cell subset,most of which are at the G0 phase.ABCG2 and MDR1 genes are highly expressed in SP cells,which particularly plays a important role in the multidrug resistance of multiple myeloma stem cell lines.
ABSTRACT
STUDY DESIGN: Retrospective, case control evaluation of 86 patients who underwent microendoscopic discectomy (MED) and percutaneous transforaminal endoscopic discectomy (PTED) for the treatment of lumbar disc herniation (LDH). PURPOSE: To evaluate the safety and the outcomes of MED and PTED for the treatment of LDH. OVERVIEW OF LITERATURE: MED and PTED are minimally invasive surgical techniques for lower back pain. Studies to date have shown that MED and PTED are safe and effective treatment modalities for LDH. METHODS: A retrospective study was performed in patients with LDH treated with MED (n=50) and transforaminal endoscopic discectomy (PTED; n=36) in our hospital. All patients were followed-up with self-evaluation questionnaires, Oswestry disability index (ODI), medical outcomes study 36-item short form health survey and MacNab criteria. All the patients in both groups were followed up to 12 months after the operation. RESULTS: ODI questionnaire responses were not statistically different between the MED and PTED groups (53.00 vs. 48.72) before treatment. Average scores and minimal disability after 5 days to 12 months of follow-up were 4.96 in the MED group and 3.61 in the PTED group. According to MacNab criteria, 92.0% of the MED group and 94.4% of the PTED group had excellent or good results with no significant difference. CONCLUSIONS: There was no significant difference between MED and PTED outcomes. Further large-scale, randomized studies with long-term follow-up are needed.

Severity, ocular trauma in agriculture and health awareness are the major predisposing factors.
ABSTRACT
Cardiopulmonary resuscitation (CPR) is series of rescue measures for saving cardiac arrest patients. Early initiation and good quality of CPR is crucial for increasing chance of survival from out-of-hospital cardiac arrest. In recent years, the CPR guidelines have changed a lot, especially in basic life support. The guideline now pays more attention on chest compression and less to ventilation. CPR with chest compression only and without mouth-to-mouth ventilation is more popular. In this article, we outline the development and recent researches of CPR. As depriving oxygen from a collapsed patient for 6 min may result in poor outcome, the average time for ambulance transport is longer (about 10 to 16 min) in China, which makes rescuers easy to feel fatigue, chest compression only CPR is not suitable in China. Though non-professional rescuers have difficulty to perform mouth-to-mouth ventilation, they generally show a willingness to do so. To strengthen public standard CPR training including mouth-to-mouth ventilation and chest compression, is most important to promote CPR in China.

This study aims to investigate the effect of total flavones of Fructus Chorspondiatis (TFFC) on the mRNA and protein expression of collagen type I and III of rat cardiac fibroblasts (CFs) induced by angiotensin II (Ang II), and explore its anti-myocardial fibrosis molecular mechanism. Neonatal rat CFs were prepared from Sprague-Dawley rats (1-3 d after birth). The expression of collagen type I and III mRNA and protein were measured by RT-PCR and Western blotting, respectively. The study showed that stimulation of neonatal rat CFs with 100 nmol.L-1 of Ang II for 72 h resulted in a significant increase of the expression of collagen type I and III mRNA and protein. The changes on the expression level were blocked by TFFC. The results demonstrated that TFFC can inhibit myocardial fibrosis induced by Ang II in rats, which is probably associated with the collagen type I and III mRNA and protein levels up-regulated by Ang II, and TFFC was shown to decrease the expression levels of collagen type I and III mRNA and protein.

<p><b>OBJECTIVE</b>To examine the recent incidences and trends of childhood malignant solid tumors in Shanghai.</p><p><b>METHOD</b>Data from the population-based Shanghai Cancer Registry and related retrospective survey were used to analyze the patterns of incidence and trends of malignant solid tumors diagnosed between 2002 and 2010 in children aged 0-14 years. The distributions of incidences were described according to gender, age and cancer types which were classified according to International Classification of Childhood Cancer (ICCC). Annual age-standardized rates (ASRs) were adjusted by the world standard population. Approximate confidence intervals for standardized rate ratios (SRR) based Poisson distribution test-based methods were used to assess changes in incidence over the period 2002 - 2006 and 2007 - 2010.</p><p><b>RESULT</b>(1)A total of 868 cases of childhood malignant solid tumors were diagnosed in Shanghai during 2002 - 2010, accounting for 65.8% of all childhood cancers. The ASR of 2002 - 2010 was 80.2 per million for all solid tumors. (2) The ASR was higher in boys (86.3 per million) than in girls (73.8 per million) with SRR 1.2 (95%CI 1.0 - 1.3). Incidence rate was the highest in the first five years of life with 93.4 per million. The age-specific incidence rates in 5 - 9 and 10 - 14 age groups were 65.2 and 79.3 per million, respectively. (3) CNS tumors, lymphomas, germ cell tumors, neuroblastoma, and soft tissue sarcomas were the top 5 most common solid tumors in children, with the incidence rate of 23.8, 11.0, 7.8, 7.7 and 6.8 per million, respectively. The patterns of subgroups varied in different age groups. Blastomas, such as neuroblastoma, retinoblastoma, were more common in the children aged 0 - 4 years, whereas epithelial carcinomas and bone tumors developed more frequently in elder children aged 10 - 14 years. (4) Compared with the ASR in 2002 - 2006, the ASR for both genders in 2007 - 2010 had no substantial changes (78.7 per million in 2002 - 2006 and 82.9 per million in 2007 - 2010). However, among boys, the incidence rate in 2007 - 2010 was significantly higher than that in 2002 - 2006 with SRR 1.2 (95%CI: 1.0 - 1.4). For specific subgroups of cancer, there were no substantial changes. Some cautions should be taken when interpreting results involving a small number of cases per year and those with wide 95% confidence intervals.</p><p><b>CONCLUSION</b>The incidence rate of pediatric malignant solid tumors among males was higher than females during 2002 - 2010, and it differed among different age groups with the highest in the first five years of life. CNS tumor was the most common type of solid tumors in children. This was a unique characteristics comparing with adult reflected in disease spectrum and age of onset. The patterns of incidence and its trends for childhood malignant solid tumors in Shanghai could provide a basis for etiologic research and preventive interventions. The findings also suggest an urgent need for longer population-based surveillance to verify the pattern and changing trends.</p>

Background The study on normal stem cell markers provides a new way of thinking of that pathogenesis of cancer research and looking for specific markers of cancer stem cells.Importin13 (IPO13) is a novel nucleus-cytoplasm transport receptor protein of importin β family,the study on the biological behavior of IPO13 in ocular tissue and limbal neoplasms is lacking.Objective This study was to investigate the differential expression of IPO13 and p63 in human benign and malignant conjunctiva-cornea neoplasms.Methods The specimens of normal donor limbal and conjunctival tissues (6),conjunciva-cornea papilloma (CCP) (6) and conjunctiva-cornea intraepithelial neoplasia(CCIN) (6)were collected from Xiangya Hospital of Center South University.The expressions of IPO13 and p63 in the corresponding tissue were qualitatively and quantitatively detected using immunochemistry.The A values of IPO13 and p63 positive response were calculated and compared among the 3 types specimens.Results The immunohistostaining on frozen sections showed that IPO13 was expressed in nuclei of basal cells of limbal and conjunctival epithelium and the cellular nuclei of basal cells and suprabasal cells of CCP and CCIN epithelium.The A values of IPO13 positive expression were 1687± 1014,3546± 1375 and 7635 ±2854 in the normal limbal specimen,CCP and CCIN,respectively,showing a significant difference among them (F =7.23,P＜0.05),and the A value was higher in the CCP and CCIN than that in the normal limbal tissue (q =4.02,5.13,P＜0.05),and that in the CCIN was significantly elevated in comparison with CCP(q =3.45,P＜0.05).p63 was expressed in nuclei of basal cells and suprabasal of limbal,conjunctival and CCP epithelium,and was expressed in nuclei of the entire CCIN epithelium.The expressions of p63 in the normal conjunctiva-cornea tissue,CCP and CCIN were 2110± 1229,3966± 2129 and 6650± 2136 respectively,with significant difference among the three different specimens (F =6.17,P＜ 0.05),and the A value of p63 positive expression was significantly elevated in the CCP and CCIN compared with normal limbal specimen (q =4.33,5.01,P＜0.05),and that in the CCIN was significantly elevated in comparison with CCP(q=3.83,P＜0.05).Conclusions IPO13 is more specifical in marking the poorly differentiated cells in limbal epithelial proliferative lesions than p63.Compared with the normal limbal specimen,the expressions of IPO13 and p63 in CCP and CCIN specimens gradually upregulat,which suggests that IPO13 and p63 may play a positive regulatory role in conjunctiva-cornea proliferative lesions.The differential expression of IPO13 and p63 is predominant between benign and malignant limbal epithelial proliferative lesions,indicating that IPO13 and p63 may play an important role in regulating the abnormal proliferation and differentiation of limbal epithelial proliferative lesions.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the age variations of head-face morphological traits of Hakka in Guangdong Province.</p><p><b>METHODS</b>Thirty-eight physical indices of head and face of 671 Hakka adults (151 urban males, 181 urban females, 162 rural males and 177 rural females) from Meizhou city of Guangdong were investigated. Twelve physical indices of head and face were calculated and counted its indices distributions. The age changes of morphological traits of head and face were analyzed.</p><p><b>RESULTS</b>With the age growing, the rate of eyefold of the upper eyelid was increased, and the Mongoloid fold decreased, the direction of eyeslits tended to level, nasal root height dropped, the zygomatic projection was more projected, the eye color turned to lighter, the upper red lips became thinner; medium-sized facial height, nasal height, upper lip skin height, physiognomic ear length, physiognomic ear breadth and breadth of alae nasi were decreased. The index of mouth breadth, morphological facial skin fold were positively correlated with the age. The index of minimum frontal breadth, face breadth, bigonial diameter, interocular breadth, external biocular breadth, lip height, thickness of lips and horizontal head circumference were negatively correlated with the age. With the age growing, morphological facial index and vertical cephalo-facial index was ascending. Moreover, length-height index of head, transverse frontoparietal index, zygomatico-frontal index and lip index were declining.</p><p><b>CONCLUSION</b>With the age growing, the head and face measurements, physical indices and the proportion of observed indices have changed in Hakka in Guangdong province.</p>
