Objective To evaluate the impacts of health self-management club on hypertensive patients who lived in Gushan town of Fuzhou.Methods Thirty-three community hypertensive patients who partitipated in health self-management club during July and October 2010 were enrolled in this investigation.Control and awareness of high blood pressure and patients' health condition were compared before and after the intervention.Results Normal blood pressure (systolic pressure ＜ 140 mm Hg (1 mm Hg =0.133 kPa),diastolic pressure ＜90 mm Hg) was found in 19 patients after intervention ((19/31 vs 16/33),x2 =1.058,P ＞ 0.05).Meanwhile,awearness rate of normal blood pressure and mediciation order-guided drug taking was increased to 27/33 and 26/31,respectively (x2 vales were 0.047 and 1.242,respectively ; both P ＞ 0.05).Other information inluding annual blood pressure measurement in ＞ 35 years old populations was well known by more participants (x2 vales were 10.810,4.280,4.039,14.249,10.573and 14.539,respectively; all P＜ 0.05).Since intervention,blood pressure was measured at least once a month in all the subjects,and 28/31 patients measured blood pressure weekly (x2 =11.532,P ＜ 0.05).Health condition of the patients were significantly improved after intervention (Z =-2.034,P ＜ 0.05).Conclusions Community health education could raise patients' awareness of hypertension and improve their health condition.Health self-management club may be feasible to hypertensive patients living at rural-urban fringe.

Objective To observe and analyze the changes of inflammatory cytokines levels in patients with progressive cerebral infarction (PCI ).Methods The patients with progressive cerebral infarction (progressive cerebral infarction group),the patients with non-progressive cerebral infarction(non progressive cerebral infarction group)and the healthy individuals(control group)were selected as the research subjects.Sixty individuals were included in each group.The levels of IL-8,hs -CRP,SAA of the research subjects were detected and observed. Results The levels of IL -8[(201.89 ±46.41)mg/L],hs -CRP[(16.55 ±4.49)mg/L],SAA[(20.65 ± 4.17 )mg/L]of the progressive cerebral infarction group were significantly higher than those of non -progressive cerebral infarction group[(132.02 ±40.26 )mg/L,(8.09 ±4.06)mg/L and (15.35 ±4.07 )mg/L).]The differ-ences were statistically significant (t=4.289,P=0.000;t=2.276,P=0.006 and t=2.269,P=0.031).Compared with the control group[(50.70 ±31.14 )mg/L,(0.70 ±0.11 )mg/L and (5.15 ±2.21)mg/L],the levels of IL-8, hs-CRP,SAA in the progressive cerebral infarction group and non -progressive cerebral infarction group were significantly higher on the first day (PCI group vs control:t=3.614,P=0.000;t=3.406,P=0.007;t=2.559, P=0.009;NPCI group vs control:t=3.602,P=0.000;t=3.181,P=0.009;t=1.520,P=0.026).Conclusion The changes of the inflammatory factors levels such as IL-8,hs-CRP,SAA have certain predicative value on the development of the PCI.

Objective The purpose of this study was to examine effects of Isopsoralen on the osteoblast proliferation and differentiation and find its possible molecular mechanisms for anti-osteoporosis.Methods OCT-1 cells were cultured with common methods.While growing well,cells were cultured with 3 doses(10 μg·mL-1,30u μg·mL-1 and 60 μg·mL-1)of Isopsoralen for 48 h,or with purified bone morphogenetic protein 2(BMP2)protein(50 ng·mL-1).We first determined the effect of Isopsoralen on cell proliferation by MTT assay.The real time RT-PCR was also used to quantify changes in the mRNA levels of several genes,such as BMP2,Runt-related transcription factor 2(Runx2),and Osterix(Osx).We also used the Western blot analysis to evaluate the expression of Runx2 and Osx proteins.At last we used the BMP2loxp/loxp mice to isolate the primary calvaria osteoblasts,cultured with Isopsoralen of the best dose for 48 h after the in vitro conditional gene knockout technology,and tested the gene expressions of Runx2 and Osx.And the alkaline Phosphatase(ALP)staining was also performed.Result Isopsoralen(10 μg·mL-1)can promote osteoblast proliferation obviously.From the real time RT-PCR analysis,Isopsoralen can enhance the BMP2 mRNA levels,the effect of 10 μg·mL-1 was the best,and 30 μg·mL-1 followed.In addition,we found that Isopsoralen(10 μg·mL-1)can enhance the Runx2 mRNA levels significantly.We also found that lower doses of Isopsoralen can enhance the Osx mRNA levels,the effect of 30 μg·mL-1 was the best,and 10 μg·mL-1 followed.From the Western blot analysis,low doses of Isopsoralen(10 μg·mL-1 and 30 μg·mL-1)can stimulate the expression of Runx2 protein.Besides,three doses of Isopsoralen can stimulate the expression of Osx protein,and the effect of 10 μg·mL-1 and 30 μg·mL-1 are better.Finally,the results of in vitro conditional gene knockout experiment showed that the overexpression of Runx2 and Osx genes in osteoblasts,as well as ALP staining,induced by Isopsoralen are BMP2 dependent.Conclusions In this study,we firstly demonstrate that Isopsoralen can stimulate osteoblast proliferation and differentiation by mediating BMP2/Runx2/Osx signaling pathway.

Objective:To investigate the preoperative nutritional status of cardiac surgery patients in southwest China, analyze the incidence and characteristics of nutritional risk, and provide basis for establishing a standardized individualized nutritional intervention program for cardiac surgery patients.Methods:A cross-sectional survey was conducted on the nutritional status and intervention status of preoperative patients in cardiac surgery department of 23 general hospitals in Yunnan, Guizhou, Sichuan and Chongqing districts. At 00: 00 on July 7, 2022, the patients aged > 18 years old in cardiac surgery departments of the above hospitals who planned to undergo surgical treatment were enrolled as the survey objects to investigate the nutritional status on July 6, 2022 (the survey date), including basic information (general information, nutrition indicators, etc.), nutrition screening and evaluation (nutrition risk screening and organ support, etc.), nutrition treatment (nutrition supplement methods and prescriptions, etc.) and nutrition awareness of medical staff.Results:The 126 questionnaires were collected, of which 125 were valid (99.2%). ① Basic information: of the 125 patients, 67 patients were male (53.6%) and 58 patients were female (46.4%). The age ranged from 19 years old to 86 years old, with an average of (53.13±14.74) years old. Body mass index (BMI) was (22.21±3.78) kg/m 2. The age and BMI of men were significantly higher than those of women [age (years old): 56.63±13.34 vs. 49.09±15.35, BMI (kg/m 2): 22.74±3.86 vs. 21.59±3.61, both P < 0.05]. Of the 125 patients, 75 had valvular disease and 50 were with non-valvular diseases, which mainly included congenital heart disease [19 cases (15.2%)], aortic dissection [13 cases (10.4%)], coronary heart disease [12 cases (9.6%)], etc. The course of disease was 0.5 hour to 36 years, of which 93 patients (74.4%) were more than 6 months and 32 patients (25.6%) were equal to or less than 6 months. The proportion of female patients with disease duration > 6 months was significantly higher than that of male patients [87.9% (51/58) vs. 62.7% (42/67), P < 0.01]. The basic diseases mainly included hypertension [38 cases (30.4%)], coronary heart disease [12 cases (9.6%)], diabetes [7 cases (5.6%)], chronic obstructive pulmonary disease [COPD, 6 cases (4.8%)], etc. Among 125 patients, total protein (TP) < 60 g/L in 24 cases (19.2%), albumin (Alb) < 40 g/L in 64 cases (51.2%), anemia [male hemoglobin (Hb) < 120 g/L, female Hb < 110 g/L] in 33 cases (26.4%). A total of 60 cases of prealbumin data were collected, of which 23 cases (38.3%) were less than 200 mg/L.② Nutrition screening and assessment: 33.6% of the 125 patients did not undergo routine nutrition screening after admission, including the provincial and municipal tertiary hospitals. Among the 83 patients undergoing nutritional screening, 41 (32.8%) were at nutritional risk. Further analysis of patients with nutritional risk showed that of the 41 patients, 20 were male (48.8%) and 21 were female (51.2%); 27 cases (65.9%) was with valvular diseases and 14 cases (34.1%) was with non-valvular diseases; the course of disease was more than 6 months in 30 cases (73.2%), and ≤ 6 months in 11 cases (26.7%). Statistical comparison of the above 83 patients showed that women, basic disease, long term-valvular disease, anemia, low TP, and low Alb before operation were more prone to innutrition. ③ Nutritional therapy: of the 125 patients, 5 were receiving mechanical ventilation (4.0%) and 2 were using vasoactive drugs (1.6%); there were 5 cases with gastrointestinal dysfunction (4.0%), mainly manifested as abdominal distension, abdominal pain, constipation and diarrhea. One patient was treated with enteral nutrition through gastric tube combined with parenteral nutrition support, 124 patients were fed orally, and an irregular phenomenon of injecting amino acid fat emulsion through peripheral vein in 2 patients. ④ Nutrition awareness of medical staff: 124 (99.2%) of the 125 patients had a nutrition department in their hospital; 71 cases (56.8%) received nutrition education, of which 37 cases (52.1%) were consulted by the nutrition department. Of all the cases, only 38 (30.4%) were consulted by the nutrition department, of which 1 (2.6%) did not receive nutrition education after consultation. Conclusions:At present, the incidence of preoperative malnutrition in patients undergoing cardiac surgery is high in southwest China. The incidence of malnutrition in patients with basic diseases, long term-valvular disease, low TP, low Alb and anemia before operation is higher, and the incidence of malnutrition is hidden in women. The course of disease of women is longer than that of men at the time of treatment, and malnutrition is more likely to occur. The attending physicians should pay attention to the above groups. It is necessary to establish a standardized individualized nutritional intervention program and apply it to actual clinical diagnosis and treatment, so as to ultimately improve the prognosis of patients undergoing cardiac surgery and increase the benefits of patients in treatment.
