Objectives:This study aims to provide a full picture of how Health Policy and Systems Research ( HPSR) in Chinese universities. Based on the current situation, analysis of problems and challenges of the HPSR capacity has been conducted and suggestions on personnel training have been proposed. Methods: Quantitative sur-veys and qualitative interviews have been conducted among personnel engaged in HPSR from 8 representative univer-sities. Results:Most HPSR researchers in the universities are young, of which 75. 26% have doctorates and the ma-jority is trained in health care management and public health sciences. Among the current HPSR projects, health in-formation and evidence is the main research direction in this field, and both the capital investment and attention of re-searchers are high. However, research resources and funding are still currently focused on senior researchers, with limited efforts to support young scholars. HPSR has interdisciplinary and multidisciplinary characteristics, but cur-rently the collaboration among institutions and individuals is relatively limited. In addition, only 5. 81% of undertak-en HPSR projects have been translated into health policy. Discussion and Suggestions:HPSR researchers in Chinese universities are not sufficient and have similar backgrounds, resulting in limited collaboration. Investment in HPSR projects is still shallow and young researchers are vulnerable in acquiring funding resources. The ability to translate research results into policy is weak. Therefore, this paper suggests to mainstream undergraduate and postgraduate teaching, enhance the training, funding and technical support for young researchers, and to establish the mechanism of dissemination of research findings and their translation into policy.

Objective To study the changes of serum interleukin-8 (IL-8) and interleukin-10 (IL-10) in preterm infants delivered from mothers with chorioamnionitis (CA) and the possible effects on bronchopuhmonary dysplasia (BPD) and brain injury of preterm infants.Method From October 2014 to October 2015,clinical data from mothers without clinical manifestations of CA giving birth to a preterm baby (gestational age:26 to 33 weeks) were collected in Changzhou Maternal and Child Health Hospital and Suzhou Municipal Hospital.The infants were assigned to CA group and non-CA group according to their mother's placenta pathology.The levels of serum IL-8 and IL-10 were measured using enzyme-linked immunosorbent assay (ELISA) on day 1 and day 7,while the levels of WBC,CRP and PCT were measured at birth.The incidences of BPD and brain injury were also reviewed.Result A total of 67 preterm infants were included,with 51 in the CA group and 16 non-CA group.The levels of IL-8 were significantly higher in the CA group than the non-CA group on both day 1 and day 7 [(21.6 ±9.7) ng/L vs.(7.3 ±2.3) ng/L,(26.6 ± 12.9) ng/L vs.(7.3 ± 2.1) ng/L].The IL-10 levels were significantly lower on day 1 [(1.92±0.17) ng/Lvs.(2.04±0.18) ng/L] and higher on day 7 [(2.42±0.60) ng/L vs.(2.03 ±0.18) ng/L] in the CA group.Significant differences existed on the incidences of BPD (54.9％ vs.25.0％) and brain injury (74.5％ vs.43.8％) between the two groups (P ＜ 0.05).The levels of CRP and PCT were higher in CA group (P ＜ 0.05) and the WBC was similar between the two groups (P ＞ 0.05).In CA group,on both day 1 and day 7,infants with BPD had similar IL-8 and IL-10 levels comparing with infants without BPD(P ＞ 0.05),also were infants with brain injury comparing with infants without brain injury.Conclusion Chorioamnionitis in pregnant women may affect serum cytokines levels in premature infants and lead to high incidences of BPD and brain injury.

Evaluating the prevalence of kidney damage according to population-based studies in different communities has been limited in developing countries. We conducted a population-based screening study in Uygur people of Urumqi, aiming to identify the prevalence and associated risk factors of chronic kidney disease (CKD) in Uygur populations. A total of 2576 residents (>18 years) from four districts of Urumqi were interviewed from June 2007 to January 2009 and tested for haematuria, albuminuria and reduced renal function. Associations between age, gender, smoking, diabetes mellitus, hypertension, hyperuricaemia and kidney damage were examined. There were 2576 subjects enrolled in this study. After age correction, the prevalence of albuminuria, haematuria and reduced estimated glomerular filtration rate (eGFR) was 3.58%, 2.26% and 1.03%, respectively. Approximately 5.65% of the sample population had at least one indicator of kidney damage. Age, diabetes mellitus, hypercholesteremia, hyperuricaemia and hyperlipidaemia were independently associated with CKD. In the general Uygur adult population from Urumqi, 5.65% had either proteinuria, haematuria or reduced eGFR, indicating the presence of kidney damage, with an awareness of only 1.05%. The high prevalence and low awareness of CKD in this population suggest an urgent need for CKD prevention programs in Uygur people.

OBJECTIVE The objective of this study is to discuss when to dissect the lymph nodes behind the right recurrent laryngeal nerve (LN-prRLN) from the standpoint of the right cervical level Ⅵ-1 (superficial layer to the recurrent laryngeal nerve) lymph nodes in papillary thyroid carcinoma (PTC) patients.METHODS The clinical data of 306 bilateral or right PTC patients from the Hangzhou First People's Hospital who underwent dissection of level Ⅵ-1 lymph nodes and LN-prRLN between March 2014 and September 2015 were analyzed. We measured the number of level Ⅵ-1 metastatic lymph nodes and size of level Ⅵ-1 lymph nodes metastasis loci to predict the metastasis of LN-prRLN.RESULTS The number of level Ⅵ-1 metastatic lymph nodes and size of level Ⅵ-1 lymph nodes metastasis loci were risk factors of LN-prRLN metastasis(P<0.05). When the number of the level Ⅵ-1 metastatic lymph nodes was greater than 1.5, the AUC was 0.813 (the sensitivity was 78.43%, the specificity was 76.65%). The ROC showed that when the size of level Ⅵ-1 lymph nodes metastasis loci were more than 0.45 cm, the AUC was 0.726 (sensitivity was 90.20%, specificity was 48.90%).CONCLUSION In bilateral or right PTC patients with metastasis of level Ⅵ-1 lymph nodes, especially when the number of level Ⅵ-1 metastatic lymph nodes was greater than 2cm and the metastasis loci were more than 0.45 cm, we should dissect the LN-prRLN.

Objective To observe the effect of CIP4(Cdc42 interacting protein 4)on human renal tubular epithelial to mesenchymal transition(EMT)induced by transforming growth factor β1(TGF-β1)and to study the associated mechanism. Methods Human proximal tubular epithelial cells (HK-2 cell line) were cultured with TGF-β1 (10μg/L) for 72 hours. The protein expressions of E-cadherin and α-SMA were measured by Western blotting. One set of siRNA oligos specific for CIP4 and CIP4 construction of the entire coding sequence were designed based on the full CIP4 sequence in GenBank. Then HK-2 cells were transfected with CIP4-siRNA or pcDNA3.1-hCIP4 via lipofactamine 2000. The protein expressions of CIP4, E-cadherin and α-SMA were evaluated respectively in control cells, TGF-β1 treated cells, siRNA transfected cells, pcDNA3.1-hCIP4-transfected cells by Western blotting. The distribution of E-cadherin and α-SMA was observed by confocal microscope. After TGF-β1-treated HK-2 cells were interferenced with specific inhibitor of PI3K-Akt (wortmannin) 1μmol/L for 48 hours, Western blotting was used to detect the CIP4 protein in control cells and interferenced cells. Results With TGF-β1 stimulation, the expression of E-cadherin protein was decreased markedly (P＜0.05), and in contract, the expression of α-SMA were increased notably (P＜0.05), which revealed that TGF-β1 could induce EMT. After transfected with CIP4-siRNA, the protein expression of E-cadherin was increased (P＜0.05), and the protein expression of α-SMA was decreased (P＜0.05). The EMT induced by TGF-β1 was effectively reversed. After transfected with pcDNA3.1-hCIP4, the expression of E-cadherin protein was down-regnlated (P＜0.05), and the expression of α-SMA protein was up-regulated compared with control group (P＜0.05), leading to EMT. After HK-2 cells were interferenced with wortmannin for 48 hours, the expression of CIP4 was decreased (P＜0.05). Conclusion TGF-β1 upregulates the expression of CIP4 via PI3K-Akt pathway, and CIP4 may participate in EMT induced by TGF-β1.

Objective To observe the expression and localization of CIP4 (Cdc42 interacting protein-4) in the renal fibrosis and the effect of CIP4 on the expression of E-cadherin,vimentin and β-catenin tyrosine phosphorylation. Methods In vitro, the human tubular epithelial cells (HK-2 cell line) were cultured with 10 μg / L TGF-β1 for 72 h. The protein expressions of CIP4, E-cadherin, vimentin and β-catenin tyrosine phosphorylation were measured by Western blotting; the expression of CIP4 mRNA was detected by RT-PCR. The intracellular distribution of CIP4 was observe by confocal microscope. In vivo, Masson staining was used to evaluate the level of renal fibrosis; the expression and distribution of CIP4 in renal tissue were detected by immunohistochemistry. HK-2 cells were transfected with pcDNA3. 1-CIP via lipofectamine 2000. The expressions of E-cadherin, vimentin and β-catenin tyrosine phosphorylation level in the transfected cells were detected by Western blotting. Results The expressions of CIP4 mRNA and protein were up-regulated in renal tubular EMT cells. Most of CIP4 protein localized in cell membrane, and some was in cytoplasm. After stimulation by TGF-β1, the expression of CIP4 protein both in cytoplasm and nucleus was greatly increased (P ＜0.05),especially in cytoplasm. In vivo, CIP4 was expressed in renal tubular epithelia, but little expressed in glomeruli. In renal from 5/6 nephrectomized rats, CIP4 expression was significantly increased. In the CIP4 transfectants, the expression of CIP4, vimentin and β-catenin tyrosine phosphorylation level were up-regulated (P ＜0.05), but E-cadherin expression was suppressed (P ＜0.05).Conclusion The overexpression of CIP4 is likely to take part in the epithelial-to-mesenchymal transition process, thereby promoting the renal fibrosis.
