OBJECTIVE: To observe the changes of endothelium-dependent dilation (EDD) of patients with congestive heart failure (CHF) before and after Kanli Decoction treatment. METHODS: Thirty-five CHF patients were treated with Kanli Decoction. We used color Doppler ultrasound to monitor the flow-mediated dilation (FMD), pulsatile index (PI), resistance index (RI), baseline blood flow (BF), ejection fraction (EF) before and after the treatment. RESULTS: FMD after treatment (9.26+/-3.19) were obviously higher than that before the treatment (7.06+/-2.58) (P<0.05), but BF, PI and RI were not improved. CONCLUSION: Applying color Doppler ultrasound into observation on EDD of patients suffering from CHF and treated by the Kanli Decoction shows that the CHF could be treated by traditional Chinese medicine.

Objective To investigate the effect of docosahexaenoic acid (DHA) on the sensitivity of esophageal carcinoma cell line EC9706 to cisplatin and the mechanism behind this effect.Methods EC9706 cells were randomly divided into 5 groups:control group,DHA group,cisplatin (DDP) group,DHA+DDP group and endoplasmic reticulum stress (ERS) activation tunicamycin (TM) group (DHA+DDP+TM group).MTT method was used to evaluate inhibition ratio of cell proliferation.The apoptotic ratio was examined by flow eytometry.Western blot was used to detect the protein expressions of apoptosis cytokines (caspase-3 and Bcl-2) and ERS cytokines [glucose-regulated protein 78 (GRP78) and inositol-requiring enzyme 1 (IRE-1)].Results DHA causes concentration-dependent and time-dependent inhibition of the proliferation of EC9706 cells (P=0.00).DHA significantly enhanced the sensitivity of esophageal carcinoma cell line EC9706 to cisplatin.Compared to DDP treatment alone,the inhibition ratio [(60.19±5.05)％ vs.(36.72±3.52)％,P=0.02] and apoptotic ratio [(54.88±4.94)％ vs.(39.74±4.64)％,P=0.03] of EC9706 cells were enhanced by DHA+DDP treatment.Western blot showed that the expression of apoptotic factor caspase-3 protein was increased by DHA+DDP treatment.Meanwhile,the protein expressions of anti-apoptotic factor (Bcl-2) and ERS-related factors (GRP78 and IRE-1) were significantly inhibited by DHA+DDP treatment (P=0.01).However,the salutary effects of DHA were reversed by ERS activation tunicamycin.Conclusion DHA enhances the sensitivity of esophageal carcinoma cell line EC9706 to cisplatin,the mechanism of which may be the suppression of ERS response.

Objective:To explore the practical value of general anesthesia with non-intubated spontaneous breathing in uniportal thoracoscopic surgery in elderly patients.Methods:Clinical data of 86 elderly patients undergone uniportal thoracoscopy surgery during hospitalization at our hospital between March 2020 and December 2021 were retrospectively reviewed and analyzed.Based on the anesthesia intubation method, they were divided into a non-intubated spontaneous breathing video-assisted thoracic surgery group(NI-VATS group)and a one-lung ventilation video-assisted thoracic surgery group(OLV-VATS group), with 43 cases in each group.Data were compared on the inflammatory indexes, preparation time for anesthesia, time to awakening after anesthesia, intraoperative lung collapse score, mediastinal flutter score, time to postoperative feeding, digestive tract complications, sore throat, postoperative pulmonary atelectasis, and hospitalization time.Results:Compared with the OLV-VATS group, the NI-VATS group had a shorter anesthesia preparation time [(19.8±2.6)min vs.(32.3±4.5)min, t=-15.77, P<0.001]and a shorter time to awakening [(6.8±2.1)min vs.(11.9±2.9)min, t=-9.485, P<0.001], slightly poorer operating field during surgery, an unfavorable lung collapse score [(2.5±0.7) vs.(1.8±0.7) t=4.704, P<0.001], worse mediastinal flutter [(2.1±0.6) vs.(1.3±0.5), t=6.514, P<0.001]. Lower procalcitonin(PCT)[(0.189±0.130)μg/L vs.(0.264±0.123)μg/L, t=-2.744, P=0.007), a shorter time to postoperative feeding [(3.4±1.0)h vs.(5.5±1.0)h, t=-9.55, P<0.001], and lower rates of digestive tract reactions(4.7% vs.20.9%, χ2=5.108, P=0.024)and throat pain(4.7% vs.23.3%, χ2=6.198, P=0.013), and a shorter length of hospital stay [(3.8±0.3)d vs.(4.9±0.8)d, t=-7.266, P<0.001]. Conclusions:For the elderly patients undergoing uniportal thoracoscopic surgery, non-intubated spontaneous breathing may somewhat obstruct the operating field, but it can shorten the time of anesthesia and the time to awakening, does not increase complications from anesthesia and surgery, favors rapid postoperative recovery for patients and therefore should be promoted.
