Research progress on regulatory network of competitive endogenous RNA in trophoblast biological behavior in preeclampsia / 中华围产医学杂志

Preeclampsia is a unique complication in the second and third trimesters of pregnancy, but its pathogenesis remains unclear and the early diagnosis and treatment methods are yet to be perfect. Termination of pregnancy at the right time is the only way to prevent its deterioration and avoid adverse pregnancy outcomes. In recent years, with the in-depth research, non-coding RNAs has been found to be involved in many important physiological and pathological processes such as proliferation and apoptosis of trophoblast cells and these non-coding RNAs can regulate each other to form an intricate and competitive endogenous RNA regulatory network. This article will introduce the biological roles of non-coding RNAs in regulating the invasion and proliferation of trophoblast cells in patients with preeclampsia and possible regulatory relationship between non-coding RNAs. Furthermore, the potential clinical value of non-coding RNAs as diagnostic biomarkers for preeclampsia and therapeutic targets are also elaborated.

Spatial-temporal distribution characteristics of gonorrhea in Fujian province from 2010 to 2019 / 中华皮肤科杂志

Objective:To analyze the spatial-temporal distribution characteristics of gonorrhea in Fujian province from 2010 to 2019, and to provide scientific evidence for developing prevention and control strategies.Methods:Data on gonorrhea cases reported in counties and districts in Fujian province from 2010 to 2019 were collected from the National Notifiable Disease Report System of the Chinese Center for Disease Control and Prevention. OpenGeoda 1.12 software was used for global and local spatial autocorrelation analysis with Moran′s I as the statistic, and SaTScan 9.6 software was used for spatial-temporal cluster analysis to explore high-risk areas.Results:A total of 56 053 cases of gonorrhea were reported in Fujian province from 2010 to 2019. The reported incidence of gonorrhea slightly increased from 2010 to 2013, decreased from 2013 to 2014, and markedly increased from 2014 to 2018 with an average annual increase rate of 8.36%. However, the reported incidence sharply dropped again in 2019. Global autocorrelation analysis showed that the global Moran′s I index ranged from 0.48 to 0.65 between 2010 and 2019 (all P < 0.05), and there was global spatial autocorrelation of gonorrhea cases in counties and districts in Fujian province. Local autocorrelation analysis showed that the main spatial clustering patterns of gonorrhea cases in Fujian province were high-high, low-low and high-low clusters. In recent years, high-high clustering areas had shown an expanding trend, and were mainly distributed in Siming and Huli districts in Xiamen city, as well as in Licheng and Fengze districts, Jinjiang, Shishi and Nan′an county-level cities in Quanzhou city. Spatial-temporal clustering analysis revealed that the first-level spatial-temporal clustering areas were counties and districts in Xiamen city, as well as central urban areas, Jinjiang, Shishi and Nan′an county-level cities in Quanzhou city from January 2015 to December 2019. Conclusions:There was a spatial and temporal clustering of gonorrhea cases in Fujian province. High-high clustering areas were mainly distributed in the economically developed areas along the southeast coast of Fujian province, and had shown a gradually expanding trend in recent years. Counties and districts in Xiamen city, central urban areas and their surrounding county-level cities in Quanzhou city should be regarded as key areas for gonorrhea prevention and control.

Benefit of autologous stem cell transplantation in multiple myelo-ma patients at different risks after bortezomib- and/or thalido-mide-based induction therapies / 中国肿瘤临床

Objective:To evaluate the benefit of autologous stem cell transplantation (ASCT) as a consolidation therapy in the survival of multiple myeloma (MM) patients at different risks. Methods:A total of 67 MM patients who received ASCT as consolida-tion therapy between August 2006 and July 2011 were enrolled in the retrospective study. The cases were divided into three risk groups on the basis of the International Staging System and fluorescence in situ hybridization. Another 67 patients who accepted consolidation chemotherapy at the same period were selected as case-paired controls matched in terms of age, sex, optimal response after induction, and risk stratifications. All the patients received bortezomib-and/or thalidomide-based induction therapies. Results:No statistical differ-ences in non-complete remission (nCR)/complete remission (CR) rate were observed between the ASCT and chemotherapy groups (44.8%vs. 37.3%, P=0.380) after the induction therapy. The progression-free survival (PFS) was longer in the ASCT group than in the chemotherapy group (32.4 months vs. 15.1 months, P0.05). In the low-risk subgroup, only PFS was extend-ed (median: 34.8 months vs. 17.6 months, P=0.012) after ASCT, without significant improvements in the OS (P>0.05).

The microRNAs is a kind of endogenous and non-coding small RNA ,which possesses biological function negatively regulating gene expression.Recent researches also found that artificial controlling some microRNAs ex-pressions can improve heart function via regulating skeletal myoblasts through multiple mechanisms,so may become a new breakthrough point in myocardial infarction treatment area.

Evaluation of bronchial mucosa involvement in sarcoidosis patients using ¹⁸F-FDG PET-CT / 南方医科大学学报

<p><b>OBJECTIVE</b>To explore the value of ¹⁸F-FDG PET-CT in evaluating bronchial mucosa involvement in patients with saroidosis.</p><p><b>METHODS</b>A retrospective analysis was conducted among 6 sarcoidosis patients with and 14 patients without bronchial mucosa involvement to collect the data including the standard uptake value (SUVMax/Mean) of ¹⁸F-FDG, serum angiotensin converting enzyme (sACE), and proportion of lymphocytes and CD4⁺/CD8 ⁺ T lymphocyte ratio in bronchoalveolar lavage fluid (BALF).</p><p><b>RESULTS</b>The lung focal SUV(Max/Mean) was higher in patients with bronchial mucosa involvement than those without (7.04 ± 5.83/5.00 ± 4.69 vs 5.68 ± 3.66/3.82 ± 2.39), but such differences were not statistically significant (P=0.565/0.495). The SUV(Max/Mean) of the hilum of the lung and the mediastina lymph nodes were significantly higher in patients with bronchial mucosa involvement (13.28 ± 5.57/10.48 ± 4.43 vs 6.20 ± 1.77/4.52 ± 1.43, P=0.0003/0.0002; 13.84 ± 4.35/9.69 ± 2.74 vs 7.16 ± 2.52/5.28 ± 1.77, P=0.0004/0.0004). The level of sACE and CD4⁺/CD8 ⁺ T lymphocyte ratio in BALF were also significantly higher in patients with bronchial mucosa involvement (60.58 ± 16.3 vs 49.16 ± 13.3 IU/L, P=0.045; 7.30 ± 5.0 vs 2.90 ± 3.1, P=0.026). The proportion of lymphocytes in BALF was comparable between the patients with and without bronchial mucosa involvement (44.10 ± 10.3% vs 35.30 ± 12.5%, P=0.148).</p><p><b>CONCLUSIONS</b>For patients with saroidosis, ¹⁸F-FDG PET-CT is useful in evaluating bronchial mucosa involvement, which is one of the key features of active sarcoidosis.</p>

Genetic subtype and epidemiological feature of HIV-1 circulating strains among recently infected patients in Fujian province / 中华流行病学杂志

<p><b>OBJECTIVE</b>In order to evaluate the distribution of genetic subtypes and epidemiological feature of HIV-1 circulating strains in Fujian province.</p><p><b>METHODS</b>Blood samples and epidemiological data were collected from 104 newly infected patients who were distinguished by BED-CEIA methodology, during 2011-2012. Viral sequences(n = 81) of HIV-1 gag, env, and pol segments were amplified by nested PCR.</p><p><b>RESULTS</b>Subtypes B and four Circulating Recombinant Forms, (CRF01_AE, CRF07_BC, CRF08_BC and CRF55_01B) were found in the samples, CRF01_AE(45.68%)and CRF07_BC(35.80%) were the two main HIV-1 strains in Fujian province. Compared with previous data, the proportion of CRF07_BC rose significantly while it gradually decreased in CRF01_AE. Heterosexual contact was still the principal transmission route in Fujian province, but the number of infection among men-who-have-sex-with- men grew rapidly.</p><p><b>CONCLUSION</b>Results from this study suggested that different subtypes of HIV-1 strain existed in Fujian province. The distribution of subtypes and the mode of transmission were changing with the progress of epidemic. Dynamic monitoring of the molecular epidemiology trends of HIV-1 infection should be enhanced.</p>

The applied research on the diagnosis of computed tomography for the metastasis of right recurrent nerve nodes in squamous cell carcinoma of thoracic esophagus / 中华胸心血管外科杂志

Objective Study the diagnostic value of CT to assess the transfer of right recurrent nerve nodes(RRNN) on the thoracic esophageal squamous carcinoma,so as to provide reference for thoracic segment esophageal surgery way.Methods A retrospective analysis from January 2011 to February 2014 in the first affiliated hospital of zhengzhou university at the records of 132 cases of thoracic segment esophageal thoracic surgery with preoperative CT image data,recorded each patient's right recurrent nerve nodes in the largest length to diameter and the average CT number,and compared with postoperative pathologic results.Results With the ROC curve analysis,considering transfer when the length of RRNN' s diameter 8.5 mm or more in CT,the area under the curve is 0.911,the sensitivity is 85.7％,specificity is 78.8％.Considering transfer when the RRNN average CT number acuity 32.50 HU,the area under the curve is 0.815,the sensitivity is 85.7％,specificity is 76.9％.Whether RRNN transfer has significant correlation(P ＜ 0.05) with the length of tumor,tumor location and whether lymph node of other station transfer,doesn' t have significant correlation (P ＞ 0.05)with patients'age,sex,tumor differentiation degree and the T stage.Conclusion When the RRNN length to diameter 8.5 mm or RRNN average CT numberr acuity 32.50 HU,right recurrent nerve nodes should be considered lymph node metastasis,and choose chest conclusion laparoscopic radical prostatectomy.The upper thoracic portion esophageal tumor's length is 5 cm or more,or clinical suspected lymph node metastasis of other station is the risk factor for metastasis of RRNN.
