Objective To investigate the hazard of hypertension at initial diagnosis ages.Methods Using stratified cluster sampling,6 091 adults aged more than 18 years with/without hypertension were interviewed;meanwhile their blood pressures were measured.The hazard of hypertension at initial diagnosed age was analyzed with survival analysis.Results The prevalent rate of hypertension was 19.9%and the average initial diagnosed age of hypertension was 52.0?13.12)yrs.The hazard persistently increased with the age after 35 years old for male,and reached its peak of prevalent rate(26%)at the age of 75 years for female.Not significant difference of hazard existed between male and female.Conclusion Our data indicated that there is a close relationship between the risk of hypertension onset and the age,the hazard increasing with ages,especially for the population aged over 35 years old.Therefore,an early prevention of hypertension should be taken from adolescent period.

Objective To investigate the fall efficacy of elderly people in nursing homes and its influencing factors. Methods A total of 174 elderly people in 8 nursing homes in Fujian province were recruited by convenience sampling method. They were investigated with a self-designed questionnaire about the demographic data, the Modified Falls Efficacy Scale (MFES) and the Kessler Psychological Distress Scale (K10). Results The mean score of fall efficacy was 7.81±1.15, which revealed a middle level. The score of get dressed and undressed scored 9.04 ±1.42, which was the highest, while the score of using public transport scored 5.80 ±3.21, which was the lowest. Multiple regression analysis showed that the mental health status, degree of self care, age were influencing factors of fall efficacy of elderly people. Conclusions The fall efficacy level of 174 elderly people is at medium level, which is different among fall efficacy with mental health status, degree of self care, age. Individualized interventions should be designed and provided for them.

Background Increase of lens thickness at incipient cataract is a key factor of onset of primary angle-closure glaucoma (PACG).Phacoemulsification (Phaco) or phacotrabeculectomy (Phacotrabe) have been documented to be effective for the patients of PACG associated with cataract.However,which surgery is more effective and safe is lack of evidence.Objective This study was to assess and compare the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract.Methods The relevant literature was searched electronically from the PubMed (1966 to June 2011),EMB Reviews (1966 to June 2011) and Cochrane Library (Issue 1,2011).The manually searching of relevant conference proceedings was used as the supplement.The articles of randomized controlled trial (RCT) about the clinical effectiveness of Phaco versus Phacotrabe for PACG with cataract were included.The methodology quality of included literature was graded.The analysis indexes included intraocular pressure (IOP)-lowing range,postoperative administration of glaucoma drugs,incidence of positive complication,postoperative best corrective visual acuity (BCVA) and perimetry damage.The RevMan4.2 software from Cochrane Collaboration was used for the Meta analyses.Results Three RCTs about phaco versus Phacotrabe for PACG with cataract were selected in this study with the 164 eyes of 164 cases.Meta analysis showed that the IOP-lowing range was larger in the Phacotrabe group compared to only Phaco group with the WMD of 1.17 and 95％ CI of 0.06-2.27 (P =0.040),and the drug dosage of anti-glaucoma was less in the Phacotrabe group in comparison with the Phaco group with the WMD of 0.5 and 95％ CI of 0.24-0.77 (P =0.000).However,the incidence of postoperative complication was higher in the Phacotrabe group than that of the Phaco group with the RR of 0.08 and 95％ CI of 0.02-0.33 (P =0.000).No significant difference was found in the BCVA (WMD =0,95％ CI:-0.13-0.13,P=1.00) andperimetry (WMD =1.01,95％CI:0.56-1.82,P=0.98).Conclusions Compared with Phaco,Phacotrab has a better IOP-lowing effectiveness and slightly worse safety.Phaco and Phacotrab have a fairly influencc in the postoperative BCVA and perimetry.As the sample sizes of the included trials are relatively small,more welldesigned large-scale RCTs are needed.

OBJECTIVE: To develop the single-tube one-step methylation variable position (MVP) analysis technology-single-tube post-digestion PCR-melting curve analysis (PDP-MCA). METHODS: Based on differentially methylated region (DMR) reported previously as the model, a set of primers with different melting temperatures of products in the two sides of MVP were designed. By using the FastDigest methylation-sensitive restriction enzyme (MSRE), DNA digestion, multiplex amplification, MCA detection and MCA profiles were performed in a single reaction tube. Same samples (peripheral venous blood, semen, and vaginal fluid, 5 samples each type) were tested by single-tube one step MVP and traditional MSRE-PCR MCA technology. To verify the feasibility of this method, the results were compared with that of the traditional technology. The MCA/HRM profiles of different samples were analyzed and compared. RESULTS: When the melting temperature of the fragments had a differential of 2 degrees C, the MCA melting peaks separated well, and MCA detection after multiplex amplification was successful. The single-tube PDP-MCA assay was developed, which integrated multiple reactions (digestion, amplification and detection) into one tube. By this method, the sample-specific profiles and data were analyzed in 2 h, which is similar to that of the traditional method. The rapid classifications of the samples were also realized. CONCLUSION Multiplex MVPs can be analyzed in a single closed-tube. The single-tube PDP-MCA technology is a simple, fast, and automatable method. It can be used for detection of DNA methylation variations.

Objective To investigate the relationship of plasma concentration of NT-proBNP,copeptin and glasgow coma scale(GCS)scores,hematoma volumes in patients with acute cerebral hemorrhage.Methods 109 patients with acute cerebral hem-orrhage(the cerebral hemorrhage group)and 32 healthy individuals (the control group)admitted in our hospital from December 2011 to June 2013 were selected and detected for plasma NT-proBNP and copeptin.The levels of NT-proBNP,copeptin,glasgow co-ma scale(GCS)scores and hematoma volumes were compared between the two groups.Results The levels of plasma NT-proBNP and copeptin in the cerebral hemorrhage group were significantly higher than that in control group(P <0.05).The levels of plasma NT-proBNP and copeptin were significantly increased with the severity and the hematoma volume of the acute cerebral hemorrhage. The levels of NT-proBNP and copeptin are positively correlated with hematoma volumes(r=0.63,r=0.58,P <0.01)and negative-ly correlated with Glasgow Coma Scale(GCS)scores(r=-0.52,r=-0.46,P <0.01).Conclusion The levels of NT-proBNP and copeptin are positively correlated with hematoma volumes and negatively correlated with glasgow coma scale(GCS)scores.They are important clinical parameters to reflect the severity and hematoma volumes of the acute cerebral hemorrhage.

Objective To study the mechanism of anti-inflammation and bacteriostasis effect of Qinlian Liyan Heji. Methods To assess the anti-inflammatory effect, blood capillary permeability in mice was increased by acetic acid, the swelling of toe in rats was induced by albumen, and granuloma was induced by cotton ball in mice.The agar dilution method was used to check the minimal inhibitory concentration of Qinlian Liyan Heji on Staphylococcus aureus, Staphylococcus epidermidis, Moraxella catarrhalis, Klebsiella pneumoniae.The microdilution method was used to detect the minimal inhibitory concentration of Qinlian Liyan Heji on group A streptococci, Streptococcal pneumonia and Haemophilus influenzae. Results Contrast to the negative control group, Qinlian Liyan Heji significantly inhibited the increase of blood capillary permeability caused by acetic acid in the middle dose and the high dose groups.In the low dose and middle dose groups, Qinlian Liyan Heji obviously reduced the swelling of plantar in 2, 3, 4, 5 h.In the high dose group, Qinlian Liyan Heji markedly lowered the swelling of plantar in 1, 2, 3, 4, 5 h. Qinlian Liyan Heji significantly reduced the granuloma caused by cotton ball. On the other hand, Qinlian Liyan Heji exerted bacteriostatic effect on the above 7 types of bacteria. Conclusion Qinlian Liyan Heji has effects of anti-inflammation and bacteriostasis.
