Objective To study the impact of depression disorder in patients after coronary stent implantation on incidence rate of in-stent restenosis (ISR) in the coronary heart disease( CHD ), and its possible pathophysiological mechanisms. Methods According to the Hamilton Depression Scale (HAMD-24) and Self-rating Depression Scale(SDS) score,95 patients with unstable angina received coronary drug-eluting stent implantation combined with depression disorder were serve as the study group; randomly selecte 246 cases without depression due to unstable angina pectoris after coronary stent implantation as the control group in the same period. The incidence rate of ISR in these two group were observed, and serum aldosterone ( ALD), high-sensitivity C-reactive protein (hs-CRP) ,Leptin levels in two groups were compared. Results The incidence rate of ISR in study group were significantly higher than that of the control group (28/95 vs 46/246, P＜0. 05). Following with the aggravation of depression disorder,the incidence rate of ISR were elevated( χ2 =8. 148, P=0.017). Serum ALD,hs-CRP and Leptin levels of study group were significantly higher than the control group 7 days later after drug-eluting stent implantation ( ALD:277.4 ± 35.9 vs 258.9 ± 60.9, t= 3. 459, P= 0. 001; hs-CRP: 12.03 ± 3.06 vs 11.10 ±2. 806, t = 2.573, P = 0.008; Leptin:5.27 t 1.07 vs 4.98 ± 0.99, t= 2.323, P= 0.021 ). Pearson correlation analysis showed that its HAMA-24 score was positively correlated with serum ALD ,hs-CRP and Leptin( r=0.291,P=0.026; r=0.350, P=0.014; r=0. 312, P=0.023) ,and SDS score was positively correlated with hs-CRP( r=0. 302, P= 0. 020). Conclusion Serum ALD, hs-CRP and Leptin levels are higher in patients after coronary stent implantation combined with depression in patients, and the incidence rate of ISR is also higher in these patients, and the rates are elevated according to the aggravation of depression disorder.

Objective To study the effect of endovenous laser ablation combined with subfascial endoscopy therapy for venous ulcer of the lower limbs.Methods Clinical data of 112 patients undergoing endovenous laser ablation combined with subfascial endoscopy therapy for venous ulcer of the lower limbs from Oct 2011 to Feb 2016 was retrospectively evaluated.Results Patients had average 2-6 perforating veins in their affected lower limbs.Procedures were successful in all the patients,all the superficial varicose veins disappeared after 1 month and 1 year of ultrasound follow-up,perforating veins closed,ulcer healed,and chromatosis alleviated.Conclusion Endovenous laser ablation combined with subfascial endoscopy therapy for venous ulcer of the lower limbs is effective,safe and quick recovery.

Objective:To explore the clinical therapeutic effect and follow-up prognosis of preterm infants with neonatal respiratory distress syndrome (NRDS) managed by less invasive surfactant administration (LISA) and traditional intubation-surfactant-extubation (INSURE) of pulmonary surfactant (PS).Methods:Data during hospitalization and follow-up period of 187 NRDS preterm infants (gestational age 24 weeks to 31 + 6 weeks, and birth weight <1 500 g) admitted to the Department of Neonatology, the Women and Children′s Hospital of Chongqing Medical University from March 2019 to February 2021 were retrospectively analyzed.NRDS preterm infants who were injected with PS by LISA were included in the LISA group (144 cases), and those who were injected with PS by INSURE were included in the INSURE group (43 cases). The propensity score matching method was used to correct the confounding factors between groups, and the covariate equilibrium samples between groups were obtained (39 cases in each group). Clinical treatment effect and prognosis of physical development, hearing and vision development, nervous system development, respiratory system diseases and other conditions of the two groups of children were compared using the t test, Chi- square test and other statistical analysis methods as appropriate. Results:(1)Compared with that of the INSURE group, the incidence of BPD [12 cases (33.3%) vs.23 cases (63.9%), χ2=6.727, P=0.009] and ROP [13 cases (36.1%) vs.26 cases (72.2%), χ2=9.455, P=0.002] in the LISA group were significantly lower.The incidence of mild BPD [8 cases (22.2%) vs.16 cases (44.4%), χ2=4.000, P=0.046] and stage Ⅰ-Ⅱ ROP [11 cases (30.6%) vs.22 cases (61.1%), χ2=6.769, P=0.009] in the LISA group was significantly lower than that of the INSURE group.There was no significant difference in the incidence of moderate and severe BPD and stageⅢ ROP and above between groups (all P>0.05). (2)There were no statistical differences in the repeated use of PS, mechanical ventilation rate within 72 h, pneumothorax/pulmonary hemorrhage, grade Ⅲ-Ⅳ periventricula-rintraventricular hemorrhage, stage Ⅱ-Ⅲ neonatal necrotizing enterocolitis, sepsis, abnormal amplitude integrated electroencephalogram, mortality in 36 weeks of corrected gestational age, total oxygen inhalation duration and hospitalization duration between the two groups (all P>0.05). (3)Follow-up within 1 year of corrected age after discharge.There were no significant differences in extrauterine body mass, body length and head circumference development, visual development, hearing development, Neonatal Behavioral Neurological Assessment score at corrected gestational age of 40 weeks, Bayley Scales of Infants Development score at corrected gestational age of 6 months and age of 1 year, pneumonia and re-hospitalization due to respiratory diseases between groups (all P>0.05). Conclusions:PS administration with LISA technology can reduce the incidence of mild BPD and stage Ⅰ-Ⅱ ROP in premature infants with NRDS who had the gestational age of 24-31 + 6 weeks and birth weight<1 500 g, without increasing the risk of other complications.The long-term prognosis of them treated with PS administration with LISA and INSURE is similar.
