1.Progress in reguIation of phosphoIipase D mediated by Wnt/β-catenin and NF-κB signaIing pathways and its reIationships with tumorigenesis
Chinese Journal of Pharmacology and Toxicology 2014;(5):779-783
Over the last few years,elevated phospholipase D(PLD)expression and activity found to be mediated by Wnt/ β-catenin and NF-κB signaling axis sharing the same downstream genes have been involved in tumorigenesis,controlling cancer cell invasion and metastasis. New studies have revealed that Wnt signaling/ NF-κB signaling can induce PLD upregulation and increased enzymatic activ-ity. PLD/ PLD-generated phosphatidic acid( PA),as a critical regulator,might positively modulate β-catenin-dependent T-cell factor and NF-κB transcriptional activity via a targeted motif and a positive feed-back loop to reinforce pathway output including cyclin D1 ,c-myc,survivin,vascular endothelial growth factor and cyclooxygenase-2,while PLD/ PA inhibitors can reverse all the effect mentioned above and achieve significantly better anticancer effects. The PLD/ PA signaling pathway can be a novel therapeutic target for the treatment of cancer.

Chinese Journal of Hospital Administration 2021;37(1):34-38
Objective:To build a performance evaluation index system of family doctor contracting service for urban communities, so as to evaluate the effects of such service.Methods:Based on the conceptual framework of performance appraisal of family doctor contracting service, such means as Delphi method and analytic hierarchy process were employed to evaluate the performance appraisal system of such service. A measured simulation test was made in Guangzhou.Results:A library of performance appraisal candidate indexes for such service was established, based on the performance appraisal concept framework of " structure, input, output, result" of such service. A questionnaire made based on such a library was developed for correspondence inquiry of 20 experts from December 2018 to June 2019. Based on results of such inquiry, a performance appraisal system for family doctor contracting service in Guangzhou was developed, consisting of 4 level-1 indexes, 10 level-2 indexes and 34 level-3 indexes. In the system, level indexes include organizational structure and management(weight 0.21), resource input(weight 0.24), contracting service process(weight 0.19), and contracting service effect(weight 0.36). A community health center in Guangzhou was used as the measurement site, for adjustment and improvement of data acquisition methods of individual indexes or scoring criteria.Conclusions:The index system is developed scientifically; appraisal tools are designed focusing on results and outputs, ensuring the appraisal of contracting service quality from multiple perspectives of supply-demand sides and health management patterns; the system can provide appraisal tools for policy appraisal authorities to evaluate the performance of contracting service reform.

Objective Evaluate the diagnostic value of PET/CT in the preoperative advanced gastric carcinoma comparing with mult;-slice spiral computed tomography. Methods Thirty-nine advanced gastric carcinoma patients taking PET/CT and abstract 40 advanced gastric carcinoma patients performing MSCT before operation,were done the TNM staging, and the Results were compared with the operation histopathology. Results For diagnosing primary lesions, regional lymph nodes, N3 lymph nodes ,PET/CT was accurate in 92.3% , 66.7% and 100.0%.Instead, MSCT was accurate in 82.0% , 50.0% and 62.5%. Conclusions (1) PET/CT and MSCT have high accuracy in diagnosing primary lesions and regional lymph nodes. But for detecting the N3 lymph nodes and distant metastasis, PET/CT has higher accuracy than MSCT. PET/CT combining abdominoscopy may decrease or avoid exploratory laparotomy.

ObjectiveTo study the dissecting necessity of lymph node around normal and abnormal hepatic artery in distal gastric cancer undergoing D2 lymphadenectomy.MethodsSixty gastric cancer patients receiving distal D2 lymphadenectomy by the same surgeon between June 2008 to June 2010 at the Department of Gastrointestinal Surgery, First Affiliated Hospital of the Guangxi Medical University were included in this study. The lymph adipose tissue around the anatomically normal and aberrant hepatic artery was carefully dissected, and the lymph nodes sent for recombinant human cytokeratin 20 (CK20) and carcino-embryonicantigen( CEA )micrometastasisimmunohistochemistry.ResultsWiththe micrometastasis immunohistochemistry of CK20 and CEA, we found the metastasise rate of lymph node around the normal hepatic artery was 27%.Patient age, tumor size, Borrmann type, TNM staging were correlated with the lymph node metastase. There were 7 cases with abnormal hepatic artery originating from the superior mesenteric artery. The hepatic artery ran in front of the pancreas in 1 case and behind the pancreas in 6 cases. We found there are no metastases in the lymph adipose tissue surrounding the abnormal artery.ConclusionsCK20,CEA are suitable immunohistochemical targets for estimating the lymph node micrometastasis. In distal gastric cancer age at 60 or older years, tumor larger than 3 cm and Borrmann Ⅲ-Ⅳ type were risk factors for metastasis of lymph nodes around normal hepatic artery, while aberrant hepatic arteries originating from the superior mesenteric artery are much less likely to have positive lymph nodes in D2 lymphadenectomy.

Objective To investigate the relationship between the single nucleotide polymorphisms (SNPs) of TLR9 gene and the occurrence of condyloma acuminatum (CA). Methods Peripheral venous blood was obtained from 63 patients with CA and 23 normal human controls with informed consent. DNA was extracted from the blood samples and subjected to the amplification of TLR9 gene by PCR followed by sequence analysis. Results There were 4 SNPs, i.e., SNP1, SNP2, SNP3 and SNP4 at positions 1174, 1635, 1269 and 1724 of the TLR9 gene, respectively. Of these SNPs, SNP1 was located in intron 1, SNP2, SNP3 and SNP4 in exon 2. The registration number is rs352139 for SNP1, rs352140 for SNP2 in NCBI database. SNP3 and SNP4 were newly discovered positions. The frequency at SNP1 position was 0.690 and 0.609 for allele A in the patients and controls, respectively, 0.309 and 0.391 for allele G, respectively (both P > 0.05). No significant difference was observed between the patients and controls in the frequency of allele A or allele G at position SNP2 (0.302 vs. 0.698, 0.369 vs. 0.630, both P > 0.05). There were 4 haplotypes at the SNP1 and SNP2 positions, including AA, AG, GA and GG, with no significant difference in the frequency between the patients and controls (all P> 0.05). Conclusions There are 4 SNPs including SNP1, SNP2, SNP3 and SNP4 in the TLR9 gene in Guangdong Han population. SNP1 and SNP2 appear unrelated to the liability to CA.
