In recent years,challenges persist in the grassroots Party building in the university-affiliated hospitals though increased efforts have been intensified.These challenges include a lack of alignment between Party building and the hospital's central tasks,an absence of distinctive Party building brands,an insufficiently prominent role of Party organizations in hospital development,and inadequate leveraging of the Party construction for promoting medical services and cultivating medical talents.Starting from an exploration of the connotation and significance of constructing framework of"One Integration and Two Highs"in university-affiliated hospitals,this paper conducts an in-depth analysis of the existing problems and their causes within this frame-work.From a holistic perspective,the paper proposes a new path for establishing the"One Integration and Two Highs"frame-work in university-affiliated hospitals,centered around"Seven Integrations":concept integration,organization integration,strength integration,vehicle integration,culture integration,innovation integration,and assessment integration.

Objective:To investigate the clinicopathological characteristics and outcomes of a series of ovarian metastases of pancreatic ductal adenocarcinoma.Methods:Data of clinical manifestation, pathological characteristic, treatment and follow-up result from ten patients with ovarian metastases of pancreatic ductal adenocarcinoma confirmed by pathology were retrospectively analyzed.Results:The median age of onset was 46 years (38~79 years). The primary tumors were located in the body and tail of the pancreas in 8 cases. Bilateral ovarian metastasis occurred in 8 patients at the time of diagnosis. The median time from patients with clinical symptom to ovarian metastases was 2.5 months (0~12 months). Peritoneal metastasis was found in all of 10 cases. Nine cases were accompanied by CA125 elevation. The major features of metastatic carcinoma in the ovary were cystic-solid appearance (8 cases) and mucinous adenocarcinoma (6 cases) with no obvious immunohistochemical features in pathological observation. All patients underwent palliative ovariectomy at onset, and one patient underwent primary tumor resection simultaneously. Seven patients received chemotherapy. The median survival time of the 10 patients was 10.3 months.Conclusions:Ovarian metastases of pancreatic ductal adenocarcinoma are easily misdiagnosed. The final diagnosis depends on clinical manifestations, imaging and histopathological observation. Ovariectomy may be associated with better outcome.

Objective: To study the etiological characteristics of an imported Chikungunya fever (CHIK) epidemic in Fujian province in 2018. Methods: Serum samples collected at different days after the onset of the two CHIK cases were detected by real-time RT-PCR and ELISA. Structural protein E1 gene was amplified by RT-PCR and sequenced for nucleotide characteristics analysis and phylogenetic tree analysis. Results: RNA of Chikungunya virus (CHIKV) was detected in the 4 serum samples collected on the first 5 days of the disease, and the earliest IgM antibodies were detected in specimens on the 5th day of the disease, however, IgG antibodies were only detected in specimen on 10th day. Compared with the S27-African prototype strain, 12 mutant points were found in the amino acids of E1 genes in this study. The E1 genes of the two CHIK cases were exactly the same, and they were closest to the evolutionary relationship with the strain isolated in the Philippines in 2014. Their genotype was Asian genotype. Conclusions This epidemic was confirmed to have been imported from the Philippines after the infection with the Asian genotype CHIKV, which suggests that Fujian province should strengthen the monitoring of persons entering from the CHIK epidemic area, so as to prevent imported cases from causing local outbreaks.

BACKGROUND: To explore the role of protein phosphatase 2A (PP2A) in renal interstitial fibrosis by using rat model of unilateral ureteral obstructive (UUO) or cell model of human kidney proximal tubular epithelial (HK)-2 cells treated with transforming growth factor-β1 (TGF-β1).
 METHODS: 1) A total of 15 Sprague-Dawley rats were randomly divided into a sham group, a UUO group and an okadaic acid (OA) treated group (OA group) (n=5 in each group). The OA 
[30 μg/(kg·d)], diluted with 1.8% alcohol, was given to the rats in the OA group through gastric tube after at 72 h after the surgery, while the equal volume of 1.8% alcohol was given to the rats in the sham group and the UUO group. After sacrificing rats, the blood and kidney were collected to detect the renal function and the expression of PP2Ac, fibronectin (FN), collagen-I (Col-I), E-cadherin (E-cad) and α-smooth muscle actin (α-SMA) by immunohistochemistry, Western blot and RT-PCR, respectively; 2) The likely concentration of OA was determined by Trypan blue dye exclusive assay and methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay. The HK-2 cells were incubated with serum-free Dulbecco's modified eagle medium (DMEM) for 24 h; then they were divided into a control group, a TGF-β1 group (treated with 5 ng/mL TGF-β1 for 24 h) and a TGF-β1+OA group (treated with 5 ng/mL TGF-β1 and 40 nmol/L OA for 24 h). The HK-2 cells were collected and the expression of PP2Ac, FN, Col-I, E-cad and α-SMA were detected by Western blot.
 RESULTS: 1) Compared with the sham group, the BUN and Scr in the UUO group increased (both P<0.05); compared with the UUO group, the BUN and Scr in the OA group decreased (both P<0.05); the expression of PP2Ac, FN, Col-I and α-SMA was up-regulated while the expression of E-cad was down-regulated in the UUO group compared with those in the sham group (all P<0.05). The expression of PP2Ac, FN, Col-I and α-SMA was down-regulated while the expressions of E-cad was up-regulated in the OA group compared with those in the UUO group (all P<0.05); 2) The likely concentration of OA was 40 nmol/L. Western blot showed that the expression of PP2Ac, FN, Col-I and α-SMA was up-regulated while the expressions of E-cad was down-regulated in the TGF-β1 group compared with those in the control group (all P<0.05); the expression of PP2Ac, FN, Col-I and α-SMA were down-regulated while the expression of E-cad was up-regulated in the TGF-β1+OA group compared with those in the TGF-β1 group (all P<0.05).
 CONCLUSIONS PP2A might be able to promote the renal interstitial fibrosis.

OBJECTIVETo screen novel miRNAs targeting EZH2 3' untranslated region (UTR) in recombinational MCF-7 breast cancer cells over-expressing EZH2 3' UTR and quantitative analyze the expressions of the screened miRNA in breast cancer cells and tissues.

METHODSA lentiviral library was transfected into the recombinant cell line MCF-7. The cells were screened with cytotoxic agents before extraction of the genome for amplification of the miRNA precursors using PCR. The screened miRNAs were identified with sequence analysis and their expressions were analyzed quantitatively with real-time PCR in breast cancer cells and tissues.

RESULTSSeven miRNAs were screened from the recombinant MCF-7 cells, namely miR-15b, miR-16-2, miR-181b2, miR-217, miR-224, miR-329-1, and miR-487b, all of which failed to be predicted by bioinformatics software. Real-time PCR showed that miR-217, miR-329-1, and miR-487b were over-expressed in MCF-7 cells, and the expression of miR-15b and miR-16-2 was significantly increased in cancer tissues compared with the adjacent tissues (P<0.05).

CONCLUSIONNovel targeted miRNAs that can not be predicted by bioinformatics software were successfully screened from MCF-7 breast cancer cells over-expressing EZH2 3' UTR. These miRNAs are expressed differentially between normal breast cells and breast cancer tissues.

Objective:To determine the role and mechanism of tranilast preventing the progression of tubulointerstilial ifbrosis in diabetic kidney disease (DKD).
Methods:Sprague-Dawley rats were randomly divided into a control group (n=6), DKD model group (n=8), low dose tranilast group [200 mg/(kg.d), n=8], and high dose tranilast group [400 mg/(kg.d), n=8]. Tranilast was administered daily after the model was built. Rats were sacrificed at day 56, 24 hour urine was collected to measure 24-hour urine albumin excretion, and blood was collected to determine the renal function and serum albumin. Then the kidneys were harvested and subjected to studies. The expression of C3aR, E-cadherin,α-SMA, fibronectin(FN), collagen I (Col I), stem cell factor (SCF) and c-kit were detected by immunohistochemical staining respectively. The expression of E-cadherin,α-SMA, FN, Col I, SCF and c-kit protein was analyzed by Western blot, and the expression of FN, Col I, SCF and c-kit mRNA was examined by RT-PCR. Results:Tranilast can inhibit the inifltration of mast cells in the kidneys of DKD rats. The expression ofα-SMA in the kidneys of DKD rats inereased signiifcantly (P<0.05), while the expression of E-cadherin decreased (P<0.05). Tranilast increased the expression of E-cadherin and decreased the expression ofα-SMA in the prophase of DKD dose dependently. The expressions of FN and Col I were increased in the tubulointerstitial ifelds in DKD model rats (P<0.05). After the tranilast treatment, these changes were relieved to a certein degree (P<0.05). The expression of SCF and c-kit in the tubular and interstitial tissue was slight. The increased expressions of SCF and c-kit protein and mRNA in DKD model rats were downregulated by tranilat (P<0.05). The expressions of SCF and c-kit were positively correlated with the infiltration degree of mast cells and the expressions of FN, Col I.
Conclusion:Mast cells participate in and aggravate the renal tubulointerstitial fibrosis in DKD rats. Tranilast can reverse the EMT of renal tubular cells and inhibit the tubulointersitial fibrosis of DKD by blocking the inifltration of mast cells induced by SCF/c-kit pathway.
