Objective The study was to investigate the effect of psychological intervention on emotion and long-term effect of patients with nasopharyngeal cancer treated with radiotherapy. Methods A total of 100 patients with nasopharyngeal cancer were divided into the psychological intervention group and the control group with 50 cases in each. The patients in the psychological intervention group were given psychological intervention besides receiving radiotherapy and routine nursing which were similar to the control group. Anxiety score and depression score as well as survival rates before and after radiotherapy between two groups were compared. Results There was no difference in anxiety score and depression score between two groups before radiotherapy, but after radiotherapy, the anxiety score and depression score were more remarkably reduced in the psychological intervention group than in the control group. The 1, 3, 5-year overall survival rates were 100.0%, 94.0%, 85.9% respectively in the psychological intervention group, and were 96.0%, 85.6%, 70.7% respectively in the control group. Duration from the end of radiotherapy to relapse were (32.22±16.82) months in th psychological intervention group and (20.73±13.06) months in the control group. Conclusions Psychological intervention can improve anxiety and depression and shows a tendency to defer the occurrence of relapse and to improve the survival rate in patients with nasopharyngeal cancer treated with radiotherapy. The further research need to be done.

Objective:To explore the long-term effect of endoscopic radiofrequency ablation for the treatment of unresectable ampullary carcinoma.Methods:Clinical data of patients with ampullary carcinoma who received endoscopic radiofrequency ablation in the Third Affiliated Hospital of Naval Medical University from January 2012 to May 2019 were retrospectively collected, including basic information, frequency of radiofrequency ablation, the type of biliary stent, postoperative complications, and follow-up. Kaplan-Meier method was used to analyze the survival of patients after endoscopic radiofrequency ablation. Relationship between frequency of radiofrequency ablation, type of biliary stent and overall survival time was analyzed.Results:A total of 50 patients were enrolled, including 31 males and 19 females, aged 73.0±9.7 years. Twenty-five patients (50.0%) underwent 1 radiofrequency ablation treatment, while 25 patients (50.0%) underwent radiofrequency ablation treatments more than twice. Postoperative complications occurred in 6 patients (12.0%), all of which were mild symptoms. The average follow-up was 22.3 months, with a total of 39 (78.0%) deaths, 5 (10.0%) lost to follow-up, and 6 (12.0%) surviving. The median overall survival time was 16.9 (95% CI: 9.1-24.8) months, with cumulative survival rates of 62.0%, 38.5%, 27.0%, and 12.6% at 1, 2, 3, and 5 years, respectively. The median overall survival time of those treated with radiofrequency ablation ≥2 times showed a trend of prolongation compared to patients treated once, but the difference was not statistically significant [26.7 (95% CI: 9.7-43.7) months VS 12.6 (95% CI: 4.9-20.3) months, χ2=3.049, P=0.081]. Plastic stents were used in 32 patients (64.0%) and metal stents in 18 patients (36.0%). There was no significant difference in median overall survival time between patients using metal and plastic stents [17.1 (95% CI: 6.1-28.0) months VS 15.9 (95% CI: 6.9-24.9) months， χ2=0.029， P=0.865]. Conclusion:Endoscopic radiofrequency ablation is a safe treatment for unresectable ampullary carcinoma, and multiple consecutive treatments may increase the survival benefit.

Objective:To investigate the efficacy of endoscopic stent placement for patients with Bismuth type Ⅳ hilar cholangiocarcinoma.Methods:Data of 229 patients with unresectable Bismuth type Ⅳ hilar cholangiocarcinoma who successfully underwent endoscopic stent placement at the Department of Endoscopy, the Third Affiliated Hospital of Naval Medical University from January 2002 to January 2019 were retrospectively analyzed. Outcomes included clinical success rate, complication incidence, stent patency period and overall survival time. The patency of stents and overall survival time of patients were estimated by using the Kaplan-Meier method. The independent predictors for stent patency and overall survival of patients were analyzed by a multivariate Cox proportional regression model.Results:The overall clinical success rate was 78.2% (179/229). The incidence of early cholangitis after endoscopic retrograde cholangiopancreatography was 20.5% (47/229). The median stent patency and overall survival time were 5.7 (95% CI: 4.8-6.7) months and 5.1 (95% CI: 4.2-6.0) months, respectively. Further multivariate Cox regression analysis showed that metal stent ( P<0.001, HR=0.452, 95% CI: 0.307-0.666) and bilateral stents with bilateral angiography ( P=0.036, HR=0.644, 95% CI: 0.427-0.971) were independent predictors of stent patency; total bilirubin>200 μmol/L ( P=0.001, HR=1.627, 95% CI: 1.208-2.192), metal stent ( P=0.004, HR=0.636, 95% CI: 0.467-0.866) and antitumor therapy ( P<0.001, HR=0.439, 95% CI:0.308-0.626) were independent predictors of overall survival. Conclusion:There is high incidence of cholangitis in patients with unresectable Bismuth type Ⅳ hilar cholangiocarcinoma treated with endoscopic stenting. Longer stent patency can be achieved with metal stent placement and bilateral drainage. In addition, metal stent for drainage and antitumor therapy can also help increase the survival benefit.

ObjectiveTo explore the influence of electroacupuncture combined with point bloodletting and cupping for facial nerve function recovery in acute stage of idiopathic facial palsy （IFP）. MethodsEighty patients with IFP in the acute stage were randomly divided into 40 cases each in the treatment group and the control group. In the control group， oral prednisone acetate tablets were administered during the acute stage when the disease duration was less than 10 days； and electroacupuncture and flash cupping were provided during the recovery stage when the disease duration was more than 10 days， five times a week. For treatment group in acute stage， the stellate ganglion， vagus nerve stimulation point in the auricular cavity， Yifeng （TE 17） and Tinghui （GB 2） were needled on the affected side on the basis of the treatment of control group， with Yifeng and Tinghui connecting to electroacupuncture apparatus， once a day； point bloodletting and then cupping in Yifeng 2 times a week； in recovery stage， the treatment was the same as that of the control group. Both groups were treated until the 45th day from onset. The primary outcome was the Toronto facial grading system （SFGS）， and the secondary outcomes included house-brackmann （H-B） grade， facial disability index （FDI） score， and number of H-B grade-Ⅰ cases. Adverse events were recorded in both groups. ResultsThe SFGS scores of the patients in both groups were higher on the 10th， 30th and 45th days after onset of disease compared with those before the treatment （P＜0.05）； the H-B grade was lower on the 30th and 45th days after the onset of the disease compared with those before the treatment （P＜0.05）； and the facial disability index physical function （FDIP） and facial disability index social function （FDIS） scores were higher on the 30th and 45th days after onset of disease （P＜0.05）. SFGS scores of patients in the treatment group were significantly higher than those of the control group on the 30th and 45th days after onset （P＜0.05）； H-B grade was significantly lower than that of the control group on the 30th and 45th days after onset （P＜0.05）； and FDIP scores on the 45th day after onset， and FDIS scores on the 30th and 45th days after onset were significantly higher than those of the control group （P＜0.05）. At the end of treatment， 77.50% （31 cases） achieved H-B grade-Ⅰ in the treatment group， which was more than 55.00% （22 cases） in the control group （P＜0.05）. No adverse events occurred in either group. ConclusionElectroacupuncture combined with point bloodletting and cupping for IFP in acute stage can improve the recovery degree of facial nerve function， improve effectiveness， and show a high degree of safety.

Objective: To synthesize a folic acid (FA)-modified pH-sensitive nanomicelle containing sorafenib (SF) and superparamagnetic iron oxide (SPIO), and to access its visibility in MRI and anti-cancer efficacy on hepatocellular carcinoma (HCC) in vitro. Methods: The copolymer FA-PEG-Pasp (DBA/DIP) of FA, poly(ethylene glycol), N,N-dibutylethylenediamine and N,N-diisopropylethylenediamine grafted poly (L-aspartic acid) were prepared. SF and SPIO were encapsulated inside the copolymer to synthesize the targeting micelle FA-PEG-PAsp (DBA/DIP)-SPIO/SF (FPASS). The folate-free micelle[PEG-PAsp (DBA/DIP)-SPIO/SF (PASS)] was used as nontargeting micelle. The physicochemical properties and drug release behavior of the micelles were analyzed. MRI of HepG2 cells incubated with FPASS and PASS with different Fe concentrations and Prussian blue staining of cells treated with the micelles (Fe concentration of 20 μg/ml) was performed to assess the drug delivery capability and imaging function of the micelles. For the FA competitive inhibition assay in these experiments, HepG2 cells were pre-treated with an excess amount of free FA prior to the incubation with FPASS. Cell viability, cell apoptosis, cell cycle and tube formation assays were conducted for evaluating the anti-HCC effects of the micelles. Comparison between groups was analyzed by one-way ANOVA, and multiple comparisons correction was performed by LSD test. Results: The diameters of FPASS and PASS were (102.3±5.2) nm and (107.1±5.7) nm, respectively; the δ potentials of them were (29.7±1.6) mV and (31.5±1.4) mV, respectively. The T₂ relaxivity of both the micelles was (5.2±0.4) ml·μg^-1·s^-1, which was much higher than that of water soluble Fe₃O₄ nanoparticles [(2.3±0.1) ml·μg^-1·s^-1; F=76.45, P<0.01]. SF released from the micelles was much faster at pH5.0 than at pH7.4, which indicated that the micelles had a pH-triggered drug release behavior. MRI of HepG2 cell samples revealed the signal intensity on T₂WI images and the T₂ value on T₂-map images decreased with the increasing Fe concentrations in the micelles. At the same Fe concentration (5, 10, 20 and 40 μg/ml), the cells of FPASS group exhibited a more significant decrease in T₂ signal intensity and T₂ value compared with those of PASS group or FA competitive inhibition group (F=8.69, 14.03, 27.27, 32.25 and 19.80, 45.76, 113.20, 66.80; P<0.01). Prussian blue staining verified the existing of SPIO in the cytoplasm of cells. Compared with PASS, FPASS presented significantly higher anticancer effects on inducing apoptosis, causing G0/G1 phase arrest on HepG2 cells and inhibiting tube formation on human umbilical vein endothelial cells (t=7.905, 4.399 and 3.454, respectively; P<0.01). Conclusions The pH-sensitive nanomicelle FPASS was successfully constructed. This micelle possessed a hypersensitive MRI-visible function and a targeting SF delivery capability which may contribute to a significant anti-HCC effect.
