Combined with practical experience, a stock investigation method of medicinal plants is approached from different angles, such as setting up the sample field and quadrant, doing the fieldwork, calculating the stock and annual possible gathering volume, etc. Depending on the geographical distribution features of the plants, the sample field are pointed out on topographic maps (1: 50 00 or 1: 10 000). Quadrants are set up at random or regularly according to the species and density of the plants. The locat ion, area, slop orientation, gradient,elevation, and vegetation of the sample field, also the area of quadrant and the amount of plants investigated, should be carefully noted down during the fieldwork .The quadrants are classified according to their slop orientation and gradient, then convert the recorded amonut of plants in quadrants to the amount of plants per square kilornetre. The stock of Per square kilometre is equal to the volume of the amount of the plants in per square kilometre divided by the amount of the plants per kilogram. The stock of per square kilometre multiplied by the area of earth's surface is the stock volume, which should be classified by the slop orientaion and gradient. The sum of the volunes is the total stock of a kind of plant.As to gather and make use of the medicinal plants in a gathering circle period, the annul possible gathering volume should be calculated as the stock volume of the plant divided by the gathering circle period.

By using data mining technology, the characteristics of acupoints selection of modern moxibustion for primary dysmenorrhea (PD) were analyzed. The modern literature regarding moxibustion for PDl was coll6cted~ from a comprehensive retrieval in Chinese Biomedical Medicine (CBM), China National Knowledge Infrastructure (CNKI), VIP and PubMed. The prescription database of moxihustion was established, and the association rule4 method of data mining technology was adopted to analyze characteristics and rules of acupoints selection of modern moxibustion for PD. As a result, a total of 35 acupoints were involved with a total frequency of 399. The acupoints, with higher selected frequency included Guanyuan (CV 4, 90 times), Sanyinjiao (SP 6, 47 times), Shenque (CV 8, 43 times), Zhongji (CV 3, 3 times) and Qihai (CV 6, 28 tirmes); the ratio of yin-meridian acupoints to1 yang-meridian acupoints was approximately 341; the utilization of the specific acupoints accountedfor68. 6% (24/35); the crossing acupoints were used mostly (203 "times), featured with high acupoints selected, especially Guanyuan (CV 4), Sanyinjiao CSP 6) and Zhongji (CV 3); the front-mu points (130 times), he-sa points (19 times) and lower he-sea points (18 times) were frequently used. The results reveal thiat acupoints selection of moxibustion of PD focuses on the local acupoints and comnbination with the distal acupoints. The yin-meridian acupoints are preferred and the specific acupoints are the main part of the prescription. This conclusion can also be used to optimize the choosing of acupoints in clinic.

We propose an improved version of regional competition algorithm in this paper, and apply it to the automatic segmentation of medical image series, particularly in the segmentation and recognition of brain tumor. The traditional regional competition is enhanced by combining the attractive aspects of fuzzy segmentation, and thus it provides an efficient approach to segment the fuzzy and heterogeneous medical images. In order to perform regional competition on medical image series, we utilize the segmentation result of a slice to initiate the next segmented slice, while the first slice is initialized using regional growing algorithm. Moreover, we develop an algorithm to recognize the tumors automatically, taking into account its characters. Experimental results show that our algorithm performs well on the segmentation of magnetic resonance imaging (MRI) image series with high speed and precision.

Objective To investigate the status of social adjustment in undergraduate nursing students, and to explore the influence of interpersonal relations and social support on social adjustment. Methods A total of 485 undergraduate nursing students in the School of Nursing of University of South China were investigated by using the Comprehensive Diagnostic Scale for Interpersonal Relations, Social Support Rating Scale and Chinese College Students' Adaptability Scale with stratified cluster sampling method. Results The total scores of social adjustment of undergraduate nursing students were (195.37 ± 26.63) points. The total scores of interpersonal relations were (9.18 ± 5.81) points. The total scores of social support were (36.72 ± 5.39) points. Social support and social adjustment were positively correlated (r=0.274, P<0.01), but interpersonal relations and social adjustment were negatively correlated (r=-0.490, P<0.01). The main influencing factors of social adjustment in a descending order included interpersonal dating(β=-0.390, P=0.000), interpersonal conversation(β=-0.146, P =0.024) and subjective support(β=0.133, P =0.005). Conclusions The scores of the social adjustment, social support and interpersonal relations of undergraduate nursing students are all in the middle level. The main influencing factors of social adjustment include interpersonal dating, interpersonal conversation and subjective support, particulally interpersonal dating. Educators can improve their social adjustment through improving interpersonal dating, interpersonal conversation and subjective support .

Objective To investigate the risk factors of all-cause mortality in diabetic patients on peritoneal dialysis (PD).Methods As a single-center retrospective cohort study,all incident PD patients who were catheterized at the First Affiliated Hospital of Nanchang University between November 1,2005 and February 28,2017 were included.Patients were divided into diabetes mellitus group (DM group) and non-diabetes mellitus group (NDM group).Outcomes were analyzed by Kaplan-Meier method.Multivariate Cox proportional hazards models were utilized to assess the risk factors of all-cause mortality.Results A total of 977 patients were enrolled.Compared with NDM group,patients in DM group were older (47.5±14.4 vs 59.3±11.3,P ＜ 0.01),had more cardiovascular disease (CVD) (7.5％ vs 20.3％,P ＜ 0.01),higher levels of serum hemoglobin (78.2±17.2 vs 82.3±14.6g/L,P ＜ 0.01),and lower levels of serum albumin (36.1±5.0 vs 32.7±5.6 g/L,P ＜ 0.01).The one-,three-and five-year patient survival rates of DM and NDM group were 89.7％,56.0％,31.9％ and 94.7％,81.3％,67.4％,respectively.Survival rate was significantly lower in DM group than in NDM group (x2=63.51,P ＜ 0.01).Stratified analysis showed that DM group had significant lower survival rate than NDM group in patients younger than 70 years old (x2=73.35,P ＜ 0.01),while survival rate was similar between the two groups patients older than 70 years old (x2=0.003,P=0.96).Multivariate Cox proportional hazards model analysis showed that DM (HR:1.74,95％CI:1.27-2.38,P ＜ 0.01),age (HR:1.05,95％CI:1.04-1.06,P ＜ 0.01),leukocyte (HR:1.06,95％CI:1.00-1.12,P=0.04) and triglyceride (HR:1.19,95％CI:1.07-1.32,P ＜ 0.01) were all independent risk factors for all-cause mortality of PD patients.However,age (HR:1.05,95％CI:1.04-1.07,P＜ 0.01) and alkaline phosphatase (HR:1.01,95％ CI:1.00-1.01,P=0.02) were independent risk factors for all-cause mortality of diabetic patients.Conclusions Long-term survival rate was lower in diabetic PD patients than in non-diabetic PD patients.DM,age,leukocyte and triglyceride were independent risk factors of mortality in PD patients.Age and alkaline phosphatase were independent risk factors of mortality in diabetic patients.

Objective To explore the risk factors and characteristics in patients with peritoneal dialysis who died in different periods.Methods The clinical data of new peritoneal dialysis patients in the Department of Nephrology and Peritoneal Dialysis Center of the First Affiliated Hospital of Nanchang University from November 1,2005 to February 28,2017 was retrospectively analyzed.The patients were divided into two groups according to the time of death:those who died within one year and died after one year.The risk factors of mortality between the two groups were analyzed by Cox regression model.Results A total of 997 patients were enrolled and 244 patients died.There were 69 patients (28.3％) died within one year and 175 patients (71.7％) died after one year.Cardiovascular and cerebrovascular disease was the dominating reason of death in both groups,accounting for 59.4％ (died within one year group) and 51.4％ (died after one year group) respectively.Cox regression analysis showed that for died within one year group,old age (HR=1.035,95％ CI:1.016-1.055,P＜ 0.001),low blood total calcium (HR=0.167,95％ CI:0.053-0.529,P=0.002),low albumin (HR=0.899,95％CI:0.856-0.943,P ＜ 0.001) and low apolipoprotein A1 (HR=0.274,95％CI:0.095-0.789,P=0.016) were risk factors associated with mortality.However,for died after one year group,old age (HR=1.053,95％CI:1.038-1.069,P ＜ 0.001),combined with diabetes (HR=2.181,95％CI:1.445-3.291,P ＜ 0.001) and hypertriglyceride (HR=l.204,95％CI:1.065-1.362,P=0.003) were risk factors associated with mortality.Conclusions The risk factors of mortality for peritoneal dialysis patients of different periods were not exactly the same.For died within one year patients,old age,low blood total calcium,low albumin and low apolipoprotein A1 were independent risk factors for mortality.However,for died after one year patients,old age,combined with diabetes,and high triglycerides were independent risk factors for mortality.

Objective:To evaluate the role of glucagon-like peptide-1 receptor (GLP-1R) signaling pathway in sevoflurane postconditioning-induced attenuation of myocardial ischemia-reperfusion (I/R) injury in rats.Methods:Eighty SPF healthy adult male Sprague-Dawley rats, aged 8-10 weeks, weighing 300-340 g, were divided into 4 groups ( n=20 each) by a random number table method: sham operation group (group S), myocardial I/R group (group I/R), myocardial I/R plus sevoflurane postconditioning group (group ISP), and myocardial I/R plus sevoflurane postconditioning plus GLP-1R antagonist group (group ISPE). The myocardial I/R injury model was developed by ligating the left anterior descending branch of the coronary artery for 40 min followed by 2-h reperfusion in anesthetized rats.In group ISP, the rats inhaled 2.4% sevoflurane for 15 min starting from the beginning of reperfusion.In group ISPE, GLP-1R antagonist Exendin9-39 50 μg/kg (in 1 ml 0.9% normal saline) was intraperitoneally injected once a day from 28 days before development of the model, the last intraperitoneal injection was completed at 40 min before inhalation of sevoflurane, and the other treatments were the same as those previously described in group ISP.Blood samples from the abdominal aorta were collected immediately after reperfusion to determine the serum levels of creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH). Then the rats were sacrificed, and the hearts were obtained for microscopic examination of the histopathological changes of myocardial tissues (by HE staining) and the ultrastructure of cardiomyocytes (with a transmission electron microscope) for determination of the myocardial infarct size (TTC staining), expression of GLP-1R in myocardium (by immunohistochemical staining), expression of GLP-1R, cyclic adenosine monophosphate (cAMP), protein kinase A (PKA), cAMP response element-binding protein (CREB), phospho-CREB (p-CREB), B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated x protein (Bax) in myocardium (by Western blot). The ratios of p-CREB/CREB and Bcl-2/Bax were calculated. Results:Compared with group S, the serum levels of CK-MB and LDH and percentage of myocardial infarct size were significantly increased, the expression of GLP-1R was up-regulated, the expression of cAMP and PKA was down-regulated, and the p-CREB/CREB ratio and Bcl-2/Bax ratio were decreased in group I/R ( P<0.05). Compared with group I/R, the serum levels of CK-MB and LDH and percentage of myocardial infarct size were significantly decreased, the expression of GLP-1R, cAMP and PKA was up-regulated, and p-CREB/CREB ratio and Bcl-2/Bax ratio were increased in group ISP ( P<0.05). Compared with group ISP, the serum levels of CK-MB and LDH and percentage of myocardial infarct size were significantly increased, the expression of GLP-1R, cAMP and PKA was down-regulated, and the p-CREB/CREB ratio and Bcl-2/Bax ratio were decreased in group ISPE ( P<0.05). Conclusions:Sevoflurane postconditioning can attenuate myocardial I/R injury by activation of GLP-1R signal pathway and inhibition of cardiomyocyte apoptosis in rats.
