The role of the hedgehog/patched signaling pathway in epithelial stem cell proliferation: from fly to human

The hedgehog-patched (hh-ptc) intercellular signaling pathway has recently been shown to control the proliferation of epithelial stem cells in both Drosophila and vertebrates. Mutant and ectopic expression analyses in Drosophila suggest that the HH protein diffuses from the signaling cells to promote the proliferation of nearby ovarian somatic stem cells by antagonizing the suppression of its receptor PTC towards the CI transcription factor in the stem cells. Consequently, the transcription of CIdependent genes leads to stem cell proliferation. This regulatory pathway appears to function also in vertebrates,where defects in ptc cause basal cell carcinoma, tumors of epidermal stem cell origin. Basal cell carcinoma can also be induced by ectopic expression of Sonic hedgehog (shh) or Glil, the vertebrate homolog of ci. These studies suggest the conservation of the hh signaling pathway in controlling epithelial stem cell divisions among different organisms.

Physiological and Biochemical Response of Artificial Wetland Plant under Electric Field

By measuring wetland plants chlorophyll content,malondialdehyde(MDA) content and superoxide dismutase(SOD) enzyme activity,the changes of wetland plant physiological characeristics under different power strength were studied,and the mechanism of electric field on plant physiological characteristics was analyzed to provide a theoretical basis for the pollutant removal ability strengthening of artificial wetland under electricfield.The results showed that compared with the control plants,low-intensity-voltage(1 V and 3 V) had no significant effect on the normal physiological and biochemical indexes of the plants,and the growth trend was better than the control group;with the voltage increasing,plant chlorophyll content,MDA content and SOD activity were greatly affected,indicating that plants were under strong oxidative stress,and the growth was damaged.Therefore,a suitable electric field could enhance the sewage treatment effect of constructed wetland.

AIM:To investigate health-related quality of life(HRQoL) and psychological outcomes in 256 adults who had undergone liver transplantation(LT).METHODS:A stratified random sampling method was used in this follow-up multicenter study to select a representative sample of recipients undergoing either living donor liver transplantation(LDLT) or deceased donor liver transplantation(DDLT).HRQoL was measured by using the Chinese version of Medical Outcome Study Short Form-36(SF-36),and psychological outcomes by using the beck anxiety inventory(BAI) and the self-rating depression scale(SDS).Clinical and demographic data were collected from the records of the Chinese Liver Transplant Registry and via questionnaires.RESULTS:A total of 256 patients were sampled,including 66(25.8%) receiving LDLT and 190(74.2%) undergoing DDLT;15(5.9%) recipients had anxiety and four(1.6%) developed severe depression after the operation.Compared with LDLT recipients,DDLT patients had higher scores in general health(60.33 ± 16.97 vs 66.86 ± 18.42,P = 0.012),role-physical(63.64 ± 42.55 vs 74.47 ± 36.46,P = 0.048),roleemotional(61.11 ± 44.37 vs 78.95 ± 34.31,P = 0.001),social functioning(78.60 ± 22.76 vs 88.16 ± 21.85,P = 0.003),vitality(70.30 ± 15.76 vs 75.95 ± 16.40,P = 0.016),mental health(65.88 ± 12.94 vs 71.85 ± 15.45,P = 0.005),physical component summary scale(PCS,60.07 ± 7.36 vs 62.58 ± 6.88,P = 0.013) and mental component summary scale(MCS,52.65 ± 7.66 vs 55.95 ± 10.14,P = 0.016).Recipients > 45 years old at the time of transplant scored higher in vitality(77.33 ± 15.64 vs 72.52 ± 16.66,P = 0.020),mental health(73.64 ± 15.06 vs 68.00 ± 14.65,P = 0.003) and MCS(56.61 ± 10.00 vs 54.05 ± 9.30,P = 0.037) than those aged ≤ 45 years.MCS was poorer in recipients with than in those without complications(52.92 ± 12.21 vs 56.06 ± 8.16,P = 0.017).Regarding MCS(55.10 ± 9.66 vs 50.0 ± 10.0,P < 0.05) and PCS(61.93 ± 7.08 vs 50.0 ± 10.0,P < 0.05),recipients scored better than the Sichuan general and had improved overall QoL compared to patients with chronic diseases.MCS and PCS significantly correlated with scores of the BAI(P < 0.001) and the SDS(P < 0.001).CONCLUSION:Age > 45 years at time of transplant,DDLT,full-time working,no complications,anxiety and depression were possible factors influencing postoperative HRQoL in liver recipients.

Statins for primary cardiovascular prevention in the elderly

The elderly population is increasing worldwide, with subjects 〉 65 years of age constituting the fastest-growing age group. Furthermore, the elderly face the greatest risk and burden of cardiovascular disease mortality and morbidity. Although elderly patients, particularly those older 〉 75, have not been well represented in randomized clinical trials evaluating lipid-lowering therapy, the available evidence supporting the use of statin therapy in primary prevention in older individuals is derived mainly from subgroup analyses and post-hoc data. On the other hand, elderly patients often have multiple co-morbidities that require a high number of concurrent medications; this may increase the risk for drug-drug interactions, thereby reducing the potential benefits of statin therapy. The aim of this review was to present the relevant literature regarding statin use in the elderly for theft primary cardiovascular disease, with the associated risks and benefits of treatment.

Agricultural system is very complex since it deals with large data situation which comes from a number of factors. A lot of techniques and approaches have been used to identify any interactions between factors that affecting yields with the crop performances. The application of neural network to the task of solving non-linear and complex systems is promising. This paper presents a review on the use of artificial neural network （ANN） in predicting crop yield using various crop performance factors. General overview on the application of ANN and the basic concept of neural network architecture are also presented. From the literature, it has been shown that ANN provides better interpretation of crop variability compared to the other methods.

A Study on the Awareness of Fire Safety Measures for Users and Staff of Shopping Malls： The Case of Mlimani City and Quality Centre in Dar es Salaam

Shopping malls are accessed by people from all walks of life and, therefore, provision of adequate fire safety measures is equally important. In Dares Salaam, Tanzania, at large construction, use of shopping malls is a relatively new experience, and risks associated with use of shopping malls, such as fire outbreak, are not evident to frequent users. The main purpose of the study is to assess awareness of fire safety measures for users and staff of two shopping malls located in Dares Salaam. The research adopted a case study strategy, and 100 respondents were involved in the study. Both random and purposive sampling methods were used to select respondents for the study. Multiple sources of evidence were used in data collection, namely literature review, observations, questionnaires and interviews. Findings indicate that both shopping malls have in place fairly fire prevention measures with varying degrees. Majority of staff and users indicated that they know fire safety measures but their poor knowledge was reflected in assessing them on diferent equipment and installations, such as foam, hose reel, sprinklers and drenchers. The paper concludes that awarenes of fire safety measure of users and staff of the two shopping malls is relatively low. It is, therefore, recommended that provision of fire safety training and instructions, such as posters for users and seminars for staff of shopping malls, shall be a main focus of shopping malls owners and responsible authorities.

Imagery in Pride and Prejudice

Ceritinib： From Synthesis to Clinical Applications

Lung cancer is the major cause of cancer-related mortality, accountingfor over one quarter of cancer deaths. Lung cancers are generally divided into two main categories： SCLC （small cell lung cancer） and NSCLC （non-small cell lung cancer）. NSCLC accounts for approximately 85% of all lung cancers. ALK （anaplastic largecell kinase） gene rearrangements are identified and targeted resulting in promising response rates for NSCLC in early studies. Ceritinib is a second-generation ALK inhibitor that has demonstrated activity in crizotinib （the first-generation ALK inhibitor）-resistant patients. In this paper, the synthesis, pharmacodynamics, pharmacokinetics, therapeutic trials, adverse events and drug-drug interactions are briefly overviewed in order to make more scholars, medical workers and patients have a more clear and comprehensive recognition on this drug.

Comparison of the low-density lipoprotein cholesterol target value and the preventive effect of statins in elderly patients and younger patients

Objective To assess whether the low-density lipoprotein cholesterol （LDL-C） target value and preventive effect of statins are different between elderly and younger patients. Methods We investigated 304 patients with previous percutaneous coronary intervention who underwent coronary angiography from January 2007 to December 2016 for examination of recurrent ischemia beyond the early restenosis. Patients were classified into two groups： age ≥ 75 years （elderly group： n = 140） and 〈 75 years （younger group： n = 164）. Relationships between the achieved LDL-C level, incidence of late coronary events, and the effectiveness of statins were evaluated. Results During follow-up, 179 patients underwent late coronary revascularization. Recurrent ischemia presenting as acute coronary syndrome （ACS） occurred in 83 cases. Kaplan-Meier curve analysis revealed that in the younger group, recurrent ACS was significantly lower in patients with LDL-C 〈 70 mg/dL than in those with LDL-C ranging from 70 to 〈 100 mg/dL （P = 0.035）; however, there was no difference between these in the elderly group （P = 0.863）. Instead, recurrent ACS was less frequent in patients with LDL-C ranging from 70 mg/dL to 〈 100 mg/dL than in those with LDL-C ≥ 100 mg/dL in the elderly group （v = 0.033）. Statin use was associated with decreased recurrent ACS （P = 0.005）; moreover, only using statins was an independent predictor in the elderly group （HR： 0.375; P = 0.007）. Conclusions Strict control of LDL-C to 〈 70 mg/dL was effective for reducing the incidence of recurrent ACS in younger patients. However, LDL-C 〈 100 mg/dL might be sufficient as the target value of LDL-C-lowering therapy for secondary prevention of ischemic events in Japanese elderly patients.
