ABSTRACT
BACKGROUND@#Evidence on the relations of the American Heart Association's ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps.@*METHODS@#A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis.@*RESULTS@#During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed.@*CONCLUSIONS@#ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.

Objective To discuss the angiographic manifestations of hemorrhage after pancreaticoduo-denectomy (PD), and to evaluate the clinical curative effect of interventional therapy. Methods The angiographic findings and the therapeutic effect of interventional therapy for hemorrhage after PD in 19 PD patients, who were admitted to Fujian Provincial Hospital, China, during the period from January 2014 to February 2018 to receive DSA examination and interventional therapy, were retrospectively analyzed. Results Among the 19 PD patients, DSA examination showed that extravasation of contrast medium, pseudoaneurysm formation and irregular arterial lumen were observed in 16 patients, the rate of positive signs was 84.2％ (16/19) . All the 16 patients, who had positive DSA findings, received covered-stent implantation or embolization therapy for the responsible artery, except one patient who had hemorrhage from the branch of superior mesenteric artery and the super-selective catheterization for him failed. The technical success rate was 93.8％ (15/16) . Successful hemostasis was achieved in 13 patients (86.7％, 13/15) . Two patients developed recurrent bleeding and were transferred to surgical treatment. Two patients received twice angiography, the resultsshowed that pseudoaneurysm formation of gastroduodenal artery was detected in one patient, which was treated with embolization therapy, and in another patient angiography was normal and this patient was transferred to surgical treatment. Conclusion For postoperative hemorrhage of PD, DSA has diagnostic value, while interventional therapy has therapeutic value. The techniques are minimally-invasive and highlyeffective. Therefore, it is worthy of clinical popularization and application.

ABSTRACT
Objective To evaluate the use of unilateral pedicle lymphography (PLG) in preoperative localization and treatment of chyluria.Methods From October 2010 to March 2017,25 cases with severe chyluria and undergoing cystoscopy and unilateral PLG before renal pedicle lymphatic disconnection were reviewed.There were 11 males and 14 females,aged 44-71 years,with an average of 58.5 years.The course of the disease was 6 months to 30 years,with an average of 8.3 years.Of them,18 cases had undergone unilateral PLG and spiral CT angiography preoperatively.Surgical treatment was performed according to PLG imaging.Results Unilateral ureteral chyluria was discovered in 16 out of the 19 cases through cystoscopy,with the sensitivity of 84.2％ (16/19).In contrast,unilateral chyluria was only detected in 4 of the other 6 patients with bilateral chyluria.Albiduria were found in the remaining 5 cases in bladder,without ureteral excreted chyle.The sensitivity for chyluria positioning by cystoscopy was 64.5％ (20/31).The location of lesion in 19 patients with unilateral chyuria and 6 patients with bilateral chyluria could be correctly displayed by PLG and the sensitivity was 100％ (31/31).There was no significant difference in location between cystoscopy and PLG in 19 patients with unilateral chyluria (P =0.2482).But in total lesion location,the sensitivity of PLG was higher than cystoscopy(P =0.0026).Eighteen patients who had undergone PLG combined with spiral CT angiography,could not only locate the chylous fistula,but also determine the number of renal vessels as well as their relationship with diseased lymphatic vessels.Chyluria had disappeared immediately after unilateral renal pedicle lymphatic exfoliation in 23 patients.However,it still presented in the other 2 patients who were confirmed contralateral pyeloymphatic fistulas by PLG 3 months after surgery and cured by reoperation.Chyluria recurred in 6 cases during follow-up of 6 to 58 months,and 4 were confirmed bilateral pyelolymphatic fistulas by PLG.Two of these 4 cases were cured by laparoscopic surgery or open surgery,respectively.The other 2 patients were cured by conservative treatment.Moreover,2 patients with unilateral chyluria recurred in situ after the first laparoscopic surgery,which was confirmed by PLG.Notably,all these patients were cured by ESWL finally.Conclusions This study suggested that PLG displays remarkable advantage in terms of localization sensitivity.PLG combined with spiral CT angiography preoperatively can not only locate the chylous fistula,but also determine the number of renal vessels as well as their relationship with diseased lymphatic vessels.Depending on PLG and spiral CT angiography,renal pedicle lymphatic disconnection can effectively protect renal vessel.In addition,it can avoid the omission of ligation for perivascular lymphatic vessels.Furthermore,PLG plays a key role in temporarily obstructing the leakage of pyelolymphatic fistulas to some extent.
ABSTRACT
To study the effects of different frequency sinusoidal electromagnetic fields on the bone mineral density and bone histomorphometry of SD young rats, and to screen suitable electromagnetic field frequency. In total 32 female SD rats of 8 weeks old were randomly divided into 4 groups: control group, 15 Hz group, 30 Hz group and 45 Hz group. Except for the control group, rats in experimental groups were treated with corresponding frequency of 1.8 mT sinusoidal electromagnetic field 90 minutes every day. Rats were measured for bone mineral density after 8 weeks by dual energy X-ray absorptiometry. Rats' femur and vertebral bones were measured by analyzing the static and dynamic forms on the right tibia bone for morphometrics. Rat serum was measured to estimate the index of bone formation and bone resorption. Bone mineral density of rats from 15 Hz group and 45 Hz group was higher than that of the control group (P<0.05). Serum osteocalcin level of rats from 15 Hz group and 45 Hz group was higher than that of the control group (P<0.05). Double fluorescence spacing and static parameters of bone tissue in experimental group rat tibia were higher than that of the control group (P<0.05). Our findings imply that 15 Hz and 45 Hz sinusoidal electromagnetic fields can effectively increase bone mineral density in young rats for preventing osteoporosis.
ABSTRACT
Objective:To explore the utilization of and satisfaction at community health service between migrant and non-migrant workers in Shenzhen city. Methods: Random sampling was used and 8000 community residents in Shenzhen city were investigated, and the data was analyzed with SPSS 18. 0. Results:There was statistically signifi-cant difference on the times of seeking community health services last year between migrant workers and non-migrant workers ( P<0. 0001 ) , and the proportion of more than three times service utilization of migrant workers were greater than that of non-migrant workers. The top three elements inpluencing satisfaction at community health service between migrant and non-migrant workers were service attitude ( 73. 29% vs. 73. 46%) , technical level ( 65. 29% vs. 67. 50%), and its convenience of seeking a doctor (63. 16% vs. 64. 98%). 73. 47% of users (migrant workers:74. 16%, non-migrant workers:69. 71%) were willing to accept the system of first contact in community health in-stitutions. Conclusions:The utilization of community health service has increased since implementing the system of first contact in community health institutions. Both migrant workers and non-migrant workers were very satisfied with the community health services, and the differences on satisfaction between the two groups were not significant. It is feasible to gradually promote the system of first contact in community health institutions over China.

ABSTRACT
To study the effects of 1.8 mT sinusoidal electromagnetic fields of different frequencies on bone mineral density (BMD) and biomechanical properties in young rats.A total of 32 female SD rats (6-week-old) were randomly divided into 4 groups (8 in each):control group, 10 Hz group, 25 Hz group and 40 Hz group. The experimental groups were given 1.8 mT sinusoidal electromagnetic field intervention 90 min per day. The whole body BMD of rats was detected with dual-energy X-ray absorptiometry after 4 and 8 weeks of intervention. After 8 weeks of intervention, all rats were sacrificed, and the BMD of femur and lumbar vertebra, the length and diameter of femur, the width between medial and lateral malleolus were measured. Electronic universal material testing machine was used to obtain biomechanical properties of femur and lumbar vertebra, and micro CT scan was performed to observe micro structures of tibial cancellous bone.Compared with the control group, rats in 10 Hz and 40 Hz groups had higher whole body BMD, BMD of femur, maximum load and yield strength of femur, as well as maximum load and elastic modulus of lumbar vertebra (all<0.05). But no significant differences in the length and diameter of femur, and the width between medial and lateral malleolus were observed between control group and experimental groups (all>0.05). Micro CT scan showed that the trabecular number and separation degree, bone volume percentage were significantly increased in 10 Hz and 40 Hz groups (all<0.01). Rats in 25 Hz group also had higher BMD and better in biomechanical properties than control group, but the differences were not statistically significant (all>0.05).10 and 40 Hz of 1.8 mT sinusoidal electromagnetic field can significantly improve the bone density, microstructure and biomechanical properties in young rats.

Objective To explore whether PI3K/ AKT signaling pathway participates in the inhibiting effect of Ru-tin on H2 O2-induced apoptosis in human lens epithelial cells( HLEC). Methods HLEC were divided into four groups: control group,H2 O2 group,rutin group,LY294002 group. Cell survival rates were determined by a 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay; cell apoptosis rates were monitored by flow cytometry with Annexin V-FITC and propidiun iodide(PI) staining. Western blot was used to measure the expres-sion levels of AKT and p-AKT. Results H2 O2 induced HLEC apoptosis. Compared with H2 O2 group,rutin group not only increased the expression lever of p-AKT,but also reduced cell apoptosis rate(P < 0. 01). In LY294002 group, LY294002, an inhibitor of PI3K/ AKT signaling pathway,could significantly block the change of these inde-xes produced by rutin group(P < 0. 01), but no significant change compared with H2 O2 group. Conclusion Rutin inhibits H2 O2-induced cell apoptosis and may be associated with PI3K/ AKT signaling pathway.
ABSTRACT
Objective To compare the cardiomyocyte apoptosis and early postoperative recovery in patients undergoing cardiac valve replacement under propofol-or midazolam-combined anesthesia.Methods Forty NYHA class Ⅱ or Ⅲ patients (aged 48-64 yr and weighing 45-78 kg) undergoing cardiac valve replacement with cardiopulmonary bypass (CPB) were randomly divided into midazolam group (Group M) and propofol group (Group P) (n=20each). The patients were premedicated with morphine 0.1 mg/kg i.v. and scopolamine 0.3 mg i.v. Anesthesia was induced with midazolam 0.2 mg/kg (in Group M) or propofol 2 mg/kg (in Group P) combined with fentanyl 10 μg/kg and vecuronium 0.1 mg/kg, and maintained with propofol 5 mg. kg-1·h-1 (in Group P) or midazolam 0.1 mg·kg-1·h-1(in Group M) and intermittent i.v. boluses of fentanyl and vecuronium after tracheal intubation. The patients were mechanically ventilated with PETCO2 maintained at 35-45 mm Hg. Myocardial tissues were obtained from the right atrium before and after CPB for determination of apoptosis in cardiomyocytes (by TUNEL). The apoptotic index was calculated. The expression of caspase-3 and caspase-9 was determined by immunohistochemical avidin-biotin-peroxidase complex (ABC) technique staining. The mean airway pressure (MAP) and heart rate (HR) were monitored. Aortic cross-clamping time, surgical and CPB times, spontaneous recovery of normal heart beat, emergence from anesthesia, extubation time and duration of ICU stay were recorded and compared between the two groups.Results The percentage of spontaneous recovery of normal heart beat after release of aortic cross clamp was significantly higher and the need for dobutamine support was significantly less in Group P than in Group M ( P ＜ 0.05). The emergence from anesthesia was significantly more rapid, the extubation time and the ICU stay were significantly shorter in Group P than in Group M (P＜0.05). There were no significant differences in apoptosis index and expression of caspase-3 and caspase-9 before CPB between the two groups. The apoptosis index and expression of caspase-3 and caspase-9 were significantly increased after CPB in Group M and significantly higher than those after CPB in Group P (P＜0.05).Conclusion Cardiomyocyte apoptosis in patients undergoing CPB can be inhibited and the postoperative recovery is more rapid under propofol-combined anesthesia.

ABSTRACT
Smu. 260 encodes a putative protein of 200 residues in Streptococcus mutans, a primary pathogen for human dental caries. Smu. 260 was cloned into expression vector pET28a and expressed in good amount trom the E. coli strain BL21 (DE3). Smu.260 protein was purified to homogeneity in a two-step procedure of Ni2+ chelating and size exclusion chromatography. The purified protein exists in two forms, a dimer form about 46 ku with yellow color and a tetramer form without apparent color. Crystals were obtained from the dimer protein by hanging-drop vapor-diffusion method. The crystals diffracted to about 2.3 A resolution and belong to orthorhombic space group P212121 with cell dimensions of a = 89.88A, b = 90.91 A, c = 105.17 A. The asymmetric unit is expected to contain two dimers with solvent content of 53%.
