Objective:To investigate the adherence of patients with chronic airway disease with inhalation therapy and to explore the influencing factors.Methods:A total of 180 outpatients with chronic airway disease were selected by convenient sampling. The general information, adherence of inhalation therapyquestionnaire, asthma knowledge questionnaire, chronic obstructive pulmonary disease (COPD) health literacy questionnaire (COPD-Q) were used to evaluate the general information, adherence of inhalation therapy and disease knowledge level of the patients. The severity of the disease was evaluated by asthma control test (ACT) score and COPD assessment test (CAT) score. ANOVA and t-test were used to analyze the adherence of patients with chronic airway disease, and multivariate linear regression was used to analyze the adherence. Results:The adherence score of asthma patients was 89.74 ± 7.27 and the adherence score of COPD patients was 86.80 ± 9.16, which were in the middle level. The risk factors of non-adherence of inhalation therapy were retirement, living alone and smoking. The effect of inhaled treatment time on the adherence of inhaled therapy is not linear, and the turning point of adherence decline occurs one year after the patients received inhaled therapy. The results of multiple linear regression showed that the effect of course and employment on the adherence of inhalation therapy was statistically significant.Conclusions:The adherence of chronic airway disease patients with inhalation therapy is not ideal, especially for the patients with long course, smoking, retirement and living alone, the medical staff should pay more attention, take appropriate intervention measures to improve the adherence of inhalation therapy.

ObjectiveTo assess the diagnostic value of preoperative lymphoscintigraphy for lateral lymph node metastasis in low rectal cancer. MethodsFrom May 1999 to March 2001, pelvic and lower abdominal lymphoscintigraphy with 99mTc sulfur colloid was performed on 32 patients with proven colorectal cancer one day prior to operation. Among these patients were 27 rectal cancers, 3 sigmoid cancers and 2 colon cancers. Fifteen cases of rectal cancer with the tumor located at or below the peritoneal reflection received extended lymphadenectomy with lateral dissection (D3 lymphadenectomy). The result of lymphoscintigrams was correlated with histologic lateral node examination. Results The image ratio of pararectal nodes, obturator nodes, and internal iliac aorti lymph trains was 69%, 91%, and 100% respectively. In 15 patients receiving D3 lymphadenectomy, 10 had negative lymphoscintigrams whereas 5 had positive image, and the lateral pathology positive rate was 13%(2/15). Analysis of these results revealed the sensitivity (100%), specificity (77%) and accuracy (80%) of this diagnostic method. ConclusionPelvic and lower abdominal lymphoscintigraphy with 99mTc sulfur colloid could demonstrate the lateral lymph node drainage of low rectal cancer, and the correlation with postoperative histologic lateral node examination was high enough to enable surgeons to adopt an individualized surgical approach.

Objective To explore the clinical therapeutic effect of inverted DHS and PFNA in the treatment of femoral intertrochanteric fractures. Methods A total of 97 patients with intertrochanteric fracture in our hospital from Mar. 2011 to Mar 2013 in the department of orthopaedics were randomly divided into two groups. 48 cases were included into DHS group,another 49 cases were included into PFNA group.And then the perioperative index and the average healing time,postoperative fracture reduction loss, the excellent rate of joint function recovery and the incidence of complications between the two groups were compared. Results Theoperative time,intra-operative blood loss,postopera-tive drainage,the average healing time of PFNA group were better than that in DHS group (P<0.05).The postoperative fracture reduction loss,complication incidence of PFNA group was significantly lower than that in DHS group,and the excellent rate of joint function recovery of PFNA group was significantly higher than that in DHS group (P<0.05). Conclusion PFNA is a reliable and effective therapy for femoral intertrochanteric fractures,it is of worthy of clinical application.

Objective:To compare the efficacy and safety between WangShiBaoChiWan and mosapride in the treatment of functional dyspepsia (FD).Methods:From September 2019 to September 2020, patients with postprandial fullness and early satiation who met the Rome Ⅳ criteria for FD diagnosis were enrolled from 15 hospitals, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical College. The subjects were randomly divided into WangShiBaoChiWan (experimental) group and mosapride (control) group in the ratio of 1∶1. The treatment regimens were WangShiBaoChiWan+ mosapride simulator, WangShiBaoChiWan simulator+ mosapride, respectively with a treatment period of 2 weeks. The primary efficacy outcome was the improvement rates of main symptoms before and after treatment, the secondary efficacy primary efficacy outcome was the total clinical effective rate and the change of the single symptom score. And the safety indicator included adverse events. Independent sample t-test, paired t-test and chi-square test were used for statistical analysis. Results:A total of 251 FD patients were enrolled in the full analysis set, including 124 in the experimental group and 127 in the control group; 241 FD patients were in the per-protocol analysis set, including 117 in the experimental group and 124 in the control group. The analysis of per-protocol analysis set showed that the improvement rates of the main symptoms of the experimental group and the control group were (66±29)% and (60±30)%, respectively, and the difference was not statistically significant ( P>0.05). The improvement rate of the main symptoms of the experimental group reached 117% of that of the control group, which exceeded the expected non-inferiority standard of 80%. The total clinical effective rates of the experimental group and the control group were 76.07% (89/117) and 75.81% (94/124), respectively, and the difference was not statistically significant ( P>0.05). The results of full analysis set showed that the incidence of adverse events of the experimental group and the control group was 1.62% (2/124) and 1.57% (2/127), respectively, and the difference was not statistically significant ( P>0.05). There were no serious adverse events in the two groups. Conclusion:The improvement rate of the main symptoms of WangShiBaoChiWan is not inferior to that of mosapride in the treatment of FD, and it has good safety.

Areca catechu L. medicinal materials and their preparations are widely used in clinical practice. Betelnut polyphenol is one of the main chemical components with antioxidant, anti-inflammatory, and antibacterial effects. With continuous increase of high altitude activities, tissue oxidative damage caused by high altitude hypoxia seriously affects the ability to work, and the studies on anti-hypoxia drugs are particularly important. Recent studies have shown that betelnut polyphenols have protective effects on oxidative stress injury caused by hypoxia via improving blood gas index of hypoxic organism, increasing superoxide dismutase glutathione catalase activity, and scavenging excessive free radicals. The effects of betelnut polyphenols against hypoxia and oxidative damage protection suggest that betelnut polyphenols can be used as potential anti-hypoxia drugs and posses clinical prospects.

Axonal transport of mitochondria is critical for neuronal survival and function. Automatically quantifying and analyzing mitochondrial movement in a large quantity remain challenging. Here, we report an efficient method for imaging and quantifying axonal mitochondrial transport using microfluidic-chamber-cultured neurons together with a newly developed analysis package named "MitoQuant". This tool-kit consists of an automated program for tracking mitochondrial movement inside live neuronal axons and a transient-velocity analysis program for analyzing dynamic movement patterns of mitochondria. Using this method, we examined axonal mitochondrial movement both in cultured mammalian neurons and in motor neuron axons of Drosophila in vivo. In 3 different paradigms (temperature changes, drug treatment and genetic manipulation) that affect mitochondria, we have shown that this new method is highly efficient and sensitive for detecting changes in mitochondrial movement. The method significantly enhanced our ability to quantitatively analyze axonal mitochondrial movement and allowed us to detect dynamic changes in axonal mitochondrial transport that were not detected by traditional kymographic analyses.
