Objective To observe the therapeutic effect of abdominal acupuncture combined with Chinese medicine for the treatment of functional constipation. Methods Ninety-three qi-deficiency functional constipation patients were evenly randomized into western medicine group, Chinese medicine group and combination group. The western medicine group was given oral use of Dupbalac, Chinese medicine group was given modified Buzhong Yiqi decoction, and the combination group was given abdominal acupuncture and oral use of modified Buzhong Yiqi decoction. The treatment of the three groups covered 3 months. After treatment, the therapeutic effect was evaluated accord ing to the symptom scores and the examination results of gastrointestinal kinetics. Results ( 1) The total effective rate for relieving symptoms was 100.00% in combination group, 90.32% in Chinese medicine group, and 38.71% in western medicine group, and the effect was the best in the combination group ( P<0.05). ( 2) The combination group had stronger effect on relieving dyskinesis of anal sphincter, rectal sensibility, colonic transportation than Chinese medicine group and western medicine group (P<0.05). Conclusion Abdominal acupuncture combined with Chinese medicine shows certain therapeutic effect for the treatment of qi-deficiency functional constipation, and the effect is superior to that of Chinese medicine or Dupbalac.

Atrial fibrillation (AF) is a common arrhythmia type. It affects more than 80％ of the elderly. The main hazards are stroke and other systemic thromboembolism. Compared with the strokes caused by other causes, the disability, mortality and recurrence rate of AF-related stroke are higher. Therefore, the prevention of stroke in patients with AF is critical. Anticoagulation is the core therapeutic strategy for stroke prevention in patients with AF. This article reviews various oral anticoagulants for stroke prevention in patients with AF.

Objective To investigate the association between body weight daily fluctuation and prognosis in severe trauma patients and evaluate the values of dynamical monitoring of early weight change in treatment of severe trauma.Methods A prospective cohort study was made on 65 patients with severe trauma treated between June 2015 and December 2015.There were 41 males and 24 females,with age of (54 ± 17)years.When admitted to the emergency intensive care unit (EICU),the patients were with body mass index (BMI) for (22.0 ±2.7) kg/m2,injury severity score (ISS) for (22 ±5) points,as well as acute physiology and chronic health evaluation (APACHE) Ⅱ for (15 ± 6)points.According to the survival status during hospitalization,the patients were distributed to death group (9 patients) and survival group (56 patients).Daily body weight was measured from admission by using a weighing scale to evaluate the difference of daily body weight change between two groups.The correlation between daily body weight change and volume change as well as the relationship between daily body weight change tendency and prognosis were evaluated.Results Overall,the variation of weight was negatively correlated with ICU stay in two groups.The weight variations in death group and survival group were 0.4 (0.2,0.8) kg and-0.2 (-0.7,0.2) kg,respectively (P ＜ 0.01).The cumulative weight variation between two groups within one week was 5.02 kg (95％ CI 3.97-6.07,P ＜0.01).The change of body weight was moderately correlated with corresponding fluid balance (r =0.69,P ＜ 0.01).According to the Logistic regression analysis,daily weight gain within one week was found to be positively associated with ICU mortality (OR =3.05,P ＜ 0.05).Conclusions The body weight is negatively correlated with ICU stay in severe trauma patients.The body weight change within one week in EICU is closely correlated with fluid balance and body weight increase may elevate the risk of ICU mortality.

Neuromyelitis optica spectrum disorder (NMOSD) is a kind of immune mediated inflammatory demyelinating disease of the central nervous system manifesting with optic neuritis and acute transverse myelitis,which takes a relapsing or progression course.The exact etiology and pathogenesis are not clear.There are a lot of researches on immune pathogenesis;in addition,the pathogenesis also involves genetic,environmental,oxidative stress and other factors.

PURPOSE: Chronic rhinosinusitis (CRS) is characterized by the excessive production of mucus. However, the molecular mechanism underlying mucin overproduction in CRS with or without nasal polyps (CRSwNP and CRSsNP, respectively) is poorly understood. This study was conducted to assess the importance of the transcription factor FoxA2 in mucin production and to investigate the targeting of FoxA2 as a potential therapeutic strategy for mucus hypersecretion in CRS patients. METHODS: We enrolled 15 CRSwNP patients, 15 CRSsNP patients, and 10 normal controls in this study. The expression levels of FoxA2, MUC5AC, and MUC5B in inflamed and healthy nasal tissues were examined via immunohistochemistry and quantitative reverse transcription-polymerase chain reaction, and the levels of several proinflammatory cytokines in nasal secretions were measured via FlowCytomix analysis. In addition, the expression of MUC5AC and FoxA2 was determined in polyp-derived epithelial cells and NCI-H292 cells after in vitro stimulation. RESULTS: FoxA2 was significantly down-regulated, and MUC5AC and MUC5B were significantly up-regulated in both the CRSwNP and CRSsNP patients compared to the controls (P<0.05), and the protein level of FoxA2 was negatively associated with the IL-6 level in the CRS patients (P<0.05). IL-6 significantly increased MUC5AC expression but inhibited FoxA2 expression in vitro (P<0.05). Transfection with a FoxA2 expression plasmid significantly decreased MUC5AC promoter activity (P<0.05) and inhibited IL-6-induced MUC5AC production (P<0.05). In addition, clarithromycin significantly alleviated IL-6-induced FoxA2 suppression and decreased MUC5AC expression in vitro (P<0.05). CONCLUSIONS: Our findings suggest that FoxA2 may be considered a therapeutic target for the modulation of mucus hypersecretion in CRS patients.

ObjectiveTo evaluate the effectiveness and consistency of three commonly used early colorectal cancer screening models for advanced colorectal adenoma as a noninvasive means， and to assess the predictive value of traditional Chinese medicine （TCM） tongue images in the models. MethodsPatients diagnosed with colorectal adenoma who underwent colonoscopy and pathological examination were selected as the study participants. Basic clinical data and tongue image were collected. The prediction models of Asia-Pacific colorectal screening （APCS） model， its revision （M-APCS） and colorectal neoplasia predict （CNP） model were applied to compare the predictive effects of the three models on advanced stage adenomas of the colon， the differences in clinical data and traditional Chinese medicine tongue characteristics among patients with different degrees of adenomas， and the similarities and differences in tongue characteristics among the models. The discriminative ability of the three risk models was evaluated using the area under the curve （AUC） and receiver operating characteristic （ROC） curves. The calibration was assessed using the Kuder-Richardson coefficient and the Hosmer-Lemeshow test for consistency analysis. ResultsA total of 227 patients with adenoma were analyzed， including 104 patients （45.82%） with advanced adenoma. In the detection of advanced adenoma， those with greasy coating （70 cases， 67.3%） were higher than those without greasy coating （34 cases， 32.7%， P＜0.05）. After multivariate analysis， the odds ratio （OR） value of non-greasy coating was 0.371 （0.204~0.673， P＜0.01）， indicating that non-greasy coating was a protective factor for advanced adenomas. Among the three risk models， the detection rate of advanced adenoma in the high-risk group with APCS was the highest （63.3%）， which was 1.49 times and 2.04 times that of the medium-risk group （42.6%） and the low-risk group （31.1%， P＜0.01）. The detection rate of advanced adenomas in high-risk groups of M-APCS and CNP was slightly higher than that in moderate or low risk groups （P＞0.05）. The proportion of yellow and greasy coating in high-risk group was higher than that in the medium-risk or low-risk group （P＜0.05）. For the ability to distinguish advanced and non-advanced adenomas， the AUC of APCS was 0.629 （95% CI： 0.556~0.702） and was higher than that of M-APCS （0.591） and CNP （0.586）. In calibration evaluation， Cronbach's alpha was 0.919 （＞0.7）， which indicated that the three models were consistent. In the correlation matrix， the correlation coefficients between APCS model and M-APCS model， and CNP model were 0.794 and 0.717， respectively， and the correlation coefficients between M-APCS model and CNP model were 0.873， Hosmer-Lemeshow χ² =2.552， P＞0.05， which suggested that the three models had good calibration ability. ConclusionAll three models demonstrate the efficiency to identify advanced colorectal adenoma， and their calibration ability is considered to be good. Among the three models， the APCS exhibits the highest recognition efficiency， however， the recognition accuracy of the APCS model needs improvement. The presence of a greasy coating is identified as one of the potential predictors of advanced adenoma. Consequently， it can be considered for inclusion in the risk model of advanced colorectal adenoma to enhance the accuracy.
