Objective To analyze the correlation of traditional Chinese medical constitution types withcardiovascular risk factors in community hypertension patients. Methods We defined the constitution types of 1108 community hypertension patients, created personal health archives and provided routine examination for the subjects. After that, we input and analyzed the relevant data and results by computer. Results In 1108 cases of hypertension patients, 229 (20.67%) were defined as harmony physique, 879 (79.33%) as biased physique. In patients with biased physique, phlegm-dampness physique accounted for 25.54% (283 cases) , and then came yin deficiency physique and Qi deficiency physique, which accounted for 15.16% (168 cases) and 13.18% (146 cases) , respectively. The biased physique was dominated by single biased physique with a total of 590 cases ( 67.12%) , but the complex physique was also in large quantity, with a total of 289 cases ( 32.88%) . The complex physique consisting of two kinds of single physique was commonly seen in the patients with complex physique, accounting for 15.70%. The complex physique consisting of more kinds of single physique had less percentage. Phlegm-dampness physique was a kind of physique involving the most cardiovascular risk factors. Patients with phlegm-dampness physique had higher incidence of overweight, abnormal lipid level, family history of cardiovascular disease, lack of physical exercise and electrocardiographic abnormality, and the difference was statistically significant compared with other physique types ( P<0.05 or P<0.01) . Conclusion Phlegm-dampness, yin deficiency and Qi deficiency physique are the three commonly-seen constitution types in hypertension patients. Phlegm-dampness physique is the most commonly-seen biased physique and is also a kind of physique involving the most cardiovascular risk factors. Prevention and management in consideration with the constitution characteristics and cardiovascular risk factors will be a new prospective method for the treatment of hypertension patients in community.

Objective To evaluate the harmful effects of olanzapine and quetiapine therapeusis on swallowing ability in patients with Alzheimer'disease (AD).Methods AD inpatients with behavioral and psychological symptoms were randomly divided into two groups,treated with olanzapine (n=42) or quetiapine (n=38) for 6 weeks.The patients were assessed with Kubota's water swallowing test and arterial oxygen saturation(SaO2) monitoring pre and pro treatment.Results After treatment,a significant higher score of water swallowing test (t =2.682,2.040;both P＜ 0.05)in either of two groups,and a significant raised degrade of SaO2 only in olanzapine group(t=4.313,P＜0.01)but not in quetiapine group (P＞0.05)were observed.There was a significant higher degrade of SaO2 in olanzapine group than that in quetiapine group (t=2.155,P＜0.05)at 6 weekend of the study.Before pharmacon,about 29％ (23/80) AD subjects were diagnosed as dysphagia.After pharmacon,more emerging dysphagia patients were surveyed in olanzapine group compared with that in quetiapine group(9/31 vs 2/26,x2=4.135,P＜0.05).No significant change (both P＞0.05) in scores of mini-mental state examination(MMSE) and a significant reduced score(t=3.019,2.867;both P＜0.01)of behavioral pathology in Alzheimer'disease rating scale (BEHAVE-AD) were found in both two groups at the end of study.There was no difference among the two groups with regard to score of MMSE or BEHAVE-AD after treatment(both P＞0.05).Conclusion Either olanzapine or quetiapine therapeutics might do some harmful effects on swallowing function in patients with AD,especially the former.

Objective:To provide a potential platform for transferring specific antigen against fish bacterial diseases based on attenuated Lm (EGDe-ΔactA/ΔinlB).Methods: Attenuated Lm (EGDe-ΔactA/ΔinlB) was used to express outer membrane protein K (Ompk),a conserved and effective vaccine candidate in vibrio.The identification of recombinant strains and detection of antigen genes were operated with PCR and RT-PCR,respectively.Results: The results of PCR showed that Lm-Ompk (L-O),Lm-Lmo0576-Ompk (L-L-O) and Lm-P-Ompk (L-P-O) were constructed successfully.The identity of foreign gene was 100％ compared with sequence of NCBI.The analysis of transcription showed that the expressions of Ompk in L-O,L-L-O and L-P-O were significant (P<0.001).Moreover,the expression of Ompk in the condition of antibiotic was higher than that in the BHI without antibiotic (P<0.05).Conclusion: Lm-Ompk (L-O),Lm-Lmo0576-Ompk (L-L-O) and Lm-P-Ompk (L-P-O) were constructed successfully.

Objective: To investigate the effect of Guangdong Shenqu (GSQ) on intestinal flora structure in mice with food stagnation through 16S rDNA sequencing. Methods: Mice were randomly assigned to control, model, GSQ low-dose (GSQL), GSQ medium-dose (GSQM), GSQ high-dose (GSQH), and lacidophilin tablets (LAB) groups, with each group containing 10 mice. A food stagnation and internal heat mouse model was established through intragastric administration of a mixture of beeswax and olive oil (1:15). The control group was administered normal saline, and the model group was administered beeswax and olive oil to maintain a state. The GSQL (2 g/kg), GSQM (4 g/kg), GSQH (8 g/kg), and LAB groups (0.625 g/kg) were administered corresponding drugs for 5 d. After administration, 16S rDNA sequencing was performed to assess gut microbiota in mouse fecal samples. Results: The model group exhibited significant intestinal flora changes. Following GSQ administration, the abundance and diversity index of the intestinal flora increased significantly, the number of bacterial species was regulated, and α and β diversity were improved. GSQ administration increased the abundance of probiotics, including Clostridia, Lachnospirales, and Lactobacillus, whereas the abundance of conditional pathogenic bacteria, such as Allobaculum, Erysipelotrichaceae, and Bacteroides decreased. Functional prediction analysis indicated that the pathogenesis of food stagnation and GSQ intervention were primarily associated with carbohydrate, lipid, and amino acid metabolism, among other metabolic pathways. Conclusion The digestive mechanism of GSQ may be attributed to its role in restoring diversity and abundance within the intestinal flora, thereby improving the composition and structure of the intestinal flora in mice and subsequently influencing the regulation of metabolic pathways.

Objective To detect the urinary albumin level and urinary albumin/urine creatinine ratio in patients with acute cerebral infarction and explore their relations with NEW-TOAST typing.Methods One hundred and sixty-eight patients with acute cerebral infarction,admitted to our hospital from March 2011 to March 201,were chosen in our study; and other 45 healthy subjects were used as controls; according to NEW-TOAST typing,the patients were divided into different subgroups.Their clinical data were retrospectively analyzed; the 24 hour urinary albumin level and urinary albumin/urine creatinine ratio were detected and their relation was analyzed between patient group and controls,and between patients of different subtypes; besides,the correlation of neurologic impairment (NIHSS) scores with urinary albumin/urine creatinine ratio was analyzed.Results The 24 hour urinary albumin level and urinary albumin/urine creatinine ratio was positively correlated (r=0.301,P=0.001); according to the NEW-TOAST subtypes,patients with large artery atherosclerosis and small artery occlusion had significantly higher level of 24 hour urinary albumin level and urinary albumin/urine creatinine ratio (P＜0.05).NIHSS scores and urinary albumin/creatinine ratio in patient group were positively correlated (r=0.215,P=0.001).Conclusion Acute cerebral infarction and kidney disease are closely correlated;both 24 hour urinary albumin level and urinary albumin/urine creatinine ratio can be the predictor of acute cerebral infarction and influence the prognosis.

Objective? To investigate the status of follow-up service of discharged patients from ClassⅡ or ClassⅢ comprehensive hospitals in China. Methods? In June 2018, we selected 150 clinical departments and 228 nurses of 89 ClassⅡ or ClassⅢ comprehensive hospitals in 17 provinces, Municipality and autonomous regions by convenience sampling. The self-designed questionnaire was used to investigate the ways, contents, existing problems and suggestions of follow-up of discharged patients. Results? Follow-up service was mainly carried out by nurses including ward primary nurses and full-time nurses. Besides, the follow-up was mainly with the telephone follow-up, and its content tended to disease health education and consultation. The main existing problems of discharged patients in follow-up service were "follow-up form was too simple and lacking specialty characteristics", "follow-up way was single and follow-up effects were unsatisfactory", "human resources limits and lack of special follow-up staff", "follow-up effects lacking aggregate and analysis" and"nursing problems existing in follow-up lacking following and evaluation". Nurses suggested that "aggregate as well as feedback of follow-up data should be done regularly", "increase follow-up center unified management for discharged patients", "follow-up form should reflect specialty characteristics" and "develop multidisciplinary teamwork". Conclusions? Follow-up service has great significance for improving rehabilitation and quality of life among discharged patients. There are a lot of problems in follow-up service system for discharged patients. We should perfect the common discharged follow-up forms applied to specialties, construct multidisciplinary support platforms and make follow-up management system scientific and informative.
