Objective:To detect the methylation level and mRNA expression level of peroxisome proliferator activated receptory-coactivator-1α (PGC-1α) gene in placental tissue of pregnant women with gestational diabetes (GDM) and to explore the relationship between them and fetal distress.Methods:A total of 174 pregnant women with GDM admitted to in our hospital from Jul. 2018 to Dec. 2019 were selected as the study objects, among which 78 pregnant women with fetal distress were selected as the fetal distress group; and 96 pregnant women with normal delivery and without fetal distress were the control group; during the same period, 82 normal pregnant women without GDM were selected as the healthy group. The methylation level of PGC-1α gene in placenta was detected by direct sequencing after DNA was treated with sodium bisulfite; the expression of PGC-1α mRNA in placenta was detected by real-time fluorescence quantitative PCR (qRT-PCR) ; the levels of triglyceride (TG) , total cholesterol (TC) , low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were measured by automatic biochemical analyzer; the relationship between methylation frequency of PGC-1α gene and the expression level of PGC-1α mRNA was analyzed; and the influencing factors of fetal distress were analyzed.Results:PGC-1α gene methylation frequency and TG level were higher in the fetal distress group [ (25.42±7.31) %, (4.72±0.68) mmol/L] than in the control group [ (9.26±2.67) %, (4.31±0.64) mmol/L] and the healthy group [ (3.24±1.07) %, (4.33±0.72) mmol/L]. PGC-1α gene methylation frequency was higher in the control group than in the healthy group, and the differences were statistically significant ( P<0.05) ; PGC-1α mRNA expression level in fetal distress group (0.67±0.16) is lower than that in the control group (0.74±0.14) and healthy group (1.00±0.27) . PGC-1α mRNA expression level in control group was lower than that in healthy group, and the difference was statistically significant ( P<0.05) ; the methylation frequency of PGC-1α gene was negatively correlated with the expression level of PGC-1α mRNA in pregnant women with fetal distress ( r=-0.515, P<0.05) ; the methylation of PGC-1α gene was an independent risk factor for fetal distress ( P<0.05) , and the high expression of PGC-1α mRNA was the protective factor of fetal distress ( P<0.05) . Conclusion:DNA methylation level of PGC-1α gene in pregnant women with GDM is related to fetal distress, which may be the target of gene modification for fetal distress.

Objective: To observe the correlation between Nε-carboxymethyl-Lysine (CML), the main component of advanced glycation end products and the calcification of the anterior tibial artery plaque in patients with diabetic foot post foot amputation. Methods: Sixty patients hospitalized for foot amputation operation due to diabetic foot from June 2012 to June 2016 in the Department of Orthopedics, Affiliated Hospital of Jiangsu University were prospectively recruited.The patients were categorized into mild stenosis (0n=20), moderate stenosis (50%≤stenosis<70%, n=20) and severe stenosis (70%≤stenosis≤100%, n=20) based on the color Doppler ultrasound assessed severity of anterior tibial artery stenosis.The baseline clinical data of patients were collected and anterior tibial artery was isolated.Then, HE staining, O-Cresolphthalein Complexone method, enzymic method and ELASA analysis were then performed to detect the evolution of calcification, arterial calcium content, alkaline phosphatase activity and serum CML concentration, respectively. Results: The results from both color Doppler ultrasound scan before amputation and HE staining after amputation showed that echo intensity as well as spotty blue calcium particles of anterior tibial artery plaque increased significantly in proportion to degree of stenosis and destructed elastic plate of the arterial wall was evidenced in patients with severest stenosis.The content of calcium ((2.3±0.9), (3.9±1.3), (6.6±1.7) μmol/mg, respectively, P<0.001), ALP activity ((102.4±39.4), (202.3±73.4), (483.7±117.9) U/mg, respectively, P<0.001) and serum CML level ((28.9±4.4), (37.9±5.3), (57.3±7.1)μg/L, respectively, P<0.001) increased significantly in proportion to stenosis severity.Pearson correlation analysis showed that serum CML level was positively correlated with the content of calcium (r=0.749, P<0.001) and ALP activity (r=0.923, P<0.001), respectively. Conclusions Serum CML level is positively correlated with the calcification of anterior tibial arterial plaque in patients with diabetic foot and could be used to evaluate the calcification of anterior tibial arterial plaque and stenosis degree of anterior tibial arterial in these patients.

Objective:Objective To explore the special role of nutrition specialists in the one-day-care clinic of gestational diabetes mellitus (GDM), and provide a basis for strengthening the standardized construction of one-day-care clinic.Methods:It was a retrospective observation study that the pregnant women who participated in the one-day-care clinic of GDM in our hospital without nutrition specialists in November and December 2017 were divided into control group (177 cases), and who participated in the one-day-care clinic of GDM in our hospital with nutrition specialists in January and February 2018 were divided into observation group (307 cases). The differences of pregnancy outcomes between the two groups were compared after the propensity score matching.Results:176 pairs of patients were successfully matched with a 1:1 propensity score. The incidence of macrosomia in pregnant women with GDM in the observation group (2.8%) was significantly lower than that in the control group (8.5%) ( P=0.036). There were no significant differences in the weight gain during pregnancy, the gestational week of delivery and the incidences of insulin use, hypertension during pregnancy, preeclampsia, cesarean section, premature infants, premature rupture of membranes, umbilical cord around the neck, and fetal distress between the two groups ( P>0.05). Conclusion:Nutrition specialists are indispensable in the multidisciplinary cooperation of one-day-care clinic of GDM, and they play a key role in considerably lowering the prevalence of macrosomia in GDM pregnant women.

Objective:To investigate the effect of neoadjuvant chemotherapy on the safety of laparoscopic D 2 radical resection and prognosis of patients with locally advanced gastric cancer. Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 351 patients with locally advanced gastric cancer who underwent laparos-copic D 2 radical resection in the Second Affiliated Hospital of Air Force Medical University from December 2016 to December 2021 were collected. There were 256 males and 95 females, aged (58±9)years. Of the 351 patients, 124 cases undergoing neoadjuvant chemotherapy were divided into the neoadjuvant chemotherapy group, 227 patients undergoing postoperative adjuvant chemotherapy were divided into the adjuvant chemotherapy group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) effect evaluation of neoadjuvant chemotherapy; (3) intraoperative and postoperative situations; (4) postoperative histopathological examinations; (5) follow-up. Propensity score matching was done by the 1∶1 nearest neighbor matching method. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measure-ment data with skewed distribution were represented as M(range) or M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to draw survival curves, and the Log-Rank test was used for survival analysis. Results:(1) Propensity score matching conditions and comparison of general data of patients between the two groups of patients after matching. Of 351 patients, 154 cases were successfully matched, including 77 cases in the neoadjuvant chemotherapy group and 77 cases in the adjuvant chemotherapy group. The elimination of gender, age, preoperative body mass index, clinical T staging and clinical N staging confounding bias ensured comparability between the two groups after propensity score matching. (2) Effect evaluation of neoadjuvant chemotherapy. Of the 77 patients receiving neoadjuvant chemotherapy, none of patient achieved complete response, 26 patients achieved partial response, 46 patients showed stable disease, 5 patients had progression of disease, showing the objective response rate as 33.8%(26/77) and the disease control rate as 93.5%(72/77). There were 15 males and 11 females sensitive to neoadjuvant chemotherapy, while 46 males and 5 females not sensitive, showing a significant difference between them ( χ2=11.05, P<0.05). (3) Intra-operative and postoperative situations. The operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion, time to postoperative first flatus, time to postoperative first liquid food intake, duration of postoperative hospital stay, cases with postoperative immediate complications, cost of hospital stay were (308±71)minutes, 100(range, 20?600)mL, 5, 3.0(range, 2.0?10.0)days, 4.0(range, 2.0?12.0)days, 9.0(range, 4.0?31.0)days, 7, 7.96(7.37,8.58) ten thousand yuan in patients of the neoadjuvant chemotherapy group, versus (296±67)minutes, 100(range, 20?500)mL, 4, 3.5(range, 1.0?14.0)days, 4.0(range, 2.0?15.0)days, 8.0(range, 5.0?45.0)days, 11, 8.18(7.52,9.19) ten thousand yuan in patients of the adjuvant chemotherapy group, showing no signifi-cant difference in the above indicators between the two groups ( t=1.13, Z=?0.37, χ2=0.12, Z=?1.26, ?0.33, ?0.70, χ2=1.01, Z=?1.04, P>0.05). (4) Postoperative histopathological examinations. Results of postoperative histopatho-logical examinations showed that all 154 patients achieving R 0 resection. Cases with pathological T staging as stage T1, stage T2, stage T3, stage T4, cases with pathological N staging as stage N0, stage N1, stage N2, stage N3, number of positive lymph nodes, cases with human epidermal growth factor receptor 2 (negative, positive) were 3, 7, 5, 62, 27, 19, 19, 12, 1(range, 0?28), 59, 18 in patients of the neoadjuvant chemotherapy group, versus 0, 0, 2, 75, 17, 15, 21, 24, 3(range, 0?31), 44, 33 in patients of the adjuvant chemotherapy group, showing significant differences in the above indicators between the two groups ( Z=?3.39, ?2.55, ?3.12, χ2=6.60, P<0.05). (5) Follow-up. Of the 154 patients, 143 patients were followed up for 37(range, 5?69)months. The 3-year overall survival rate and 3-year disease-free survival rate was 72.1% and 70.0%, respectively, in patients of the neoadjuvant chemotherapy group, versus 74.8% and 76.6% in patients of the adjuvant chemo-therapy group, showing no significant difference in the above indicators between the two groups ( χ2=0.14, 0.60, P>0.05). Conclusions:Compared to postoperative adjuvant chemotherapy, neoadjuvant chemotherapy does not bring additional surgical risks, but can reduce the tumor stage of patients who underwent laparoscopic D 2 radical resection for locally advanced gastric cancer. However, it does not show any advantage in improving survival of patients.
