Objective To explorethe relationship between urinary albumin-to-creatinine ratio (UACR) and blood pressure of young migrant builders in Shanghai. Methods A total of 3 195 builders (age ranged from 18 to 50) were selected from migrant builders of Shanghai Construction Group Co., Ltd. by using random clustersampling method. They were subjected to questionnaire interview, physical examination, and biochemical tests, including UACR, renal function, serum uric acid, serum lipid, and serum glucose. The participants were divided into 4 groups (I, II, III, and IV) according to the levels of UACR, and the ordinal multinomial logistic regression model was employed todetermine the relationship between UACR levels and blood pressure grouping (normal, pre-hypertension, and hypertension). Results Among the 3 195 builders, 3 112 (97. 4%) finished interview. The UACR (median [Q1-Q3]) levels and high-UACR ratio for the normal, pre-hypertension and hypertension groups were 0. 8 (0. 6-1. 2) mg/mmol, 0. 9 (0.7-1. 4) mg/mmol, and 1. 0 (0.8-1. 7) mg/mmol, and 6. 8%, 8. 0%, and 15. 6 %, respectively, with significant differences for both UACR levels and high-UARC ratios (P<0. 05) among the 3 blood pressure groups. According to the 25%, 50%, and 75% quartiles of UACR values, builders were classified into 4 groups. After adjustment of the other factors such as age, the average systolic pressures of the I, II, III, and IV UACR groups were (126. 8± 13. 3), (127. 9 ± 14. 2), (129.9 ± 14. 4), and(134. 2 ± 19. 0) mmHg (1 mmHg= 0. 133 kPa), and the average diastolic pressures of the 4 groups were (77. 6±9. 7), (78. 8±9. 2), (79. 2 ± 10. 4), and (81. 8 ± 12. 5) mmHg, respectively. UACR was positively correlated with both the average systolic pressures and diastolic pressures (P<0. 05). Logistic regression analysis showed that, after adjusting the factors such as age, body mass index, total cholesterol, and low density lipoprotein cholesterol, the odds ratio (OR) and 95% confidence interval (95% Cl) of pre-hypertension and/or hypertension, compared with I group, were 0. 98 (0. 80-1. 20), 1. 29 (1. 05-1. 58), and 1. 86 (1. 52-2. 28) for II, III, and IV groups, respectively. Conclusion The UACR is positively correlated with pre-hypertension and hypertension among young migrant builders in Shanghai.

Objective To establish an animal model with installation of gastrobiliary duct drainage (GBDD) in the primary suture after exploration of common bile duct, to assess the safety and feasibility of GBDD. Methods Thirty dogs were randomly divided into three groups: control group (n=5), primary suture group (n= 10) and GBDD group (n= 15). Serum TBil levels, bile leakage,and complications were observed and compared. Results No increase in serum TBil level was observed in the control group. However, serum TBil levels were significantly increased in the primary suture group compared to the GBDD group (P＜0. 01). GBDD were all successfully withdrawn at mean (7. 0±1.7) days after the operation. No bile leakage was found in the GBDD group, which was significantly different compared to 5/10 bile leakage cases in primary suture group (P＜0. 05). There were 3/10 cases of bile peritonitis, infection of incisional wound and splitted in the primary suture group, while there were no such complications in the GBDD group (all P＞0.05). Conclusions GBDD is safe and feasible. It can shorten biliary drainage time and prevent occurrence of bile leakage.Therefore, it has unique value in clinical application.

Objective To investigate the effect of acupuncture on gap junction protein Cx43 expression in the hippocampal region in ischemia/reperfusion rats.Methods Wistar rats were randomized into normal, model, non-point acupuncture and acupuncture groups. A rat model of focal cerebral ischemia/reperfusion was made by modified middle cerebral artery thread occlusion. The model, non-point acupuncture and acupuncture groups were separately divide into four subgroups: 30, 60, 180 and 360 min ischemia/reperfusion, 10 rats each. The middle and lateral lines of vertex were given electroacupuncture in the acupuncture group of rats. A subcostal fixed point 10 mm above the iliac crest on the affect side was selected as an acupuncture point in the non-point acupuncture group. The model group was not treated. Cx43 protein expression was determined by an immunohistochemical method.Results There was a statistically significant difference in the behavior disorder (Bederson’s) score between the acupuncture group and the non-point acupuncture or model group after different times of cerebral ischemia/ reperfusion (P<0.05). There was a statistically significant difference in hippocampal Cx43 content between model, acupuncture or non-point acupuncture group and the normal group and between the acupuncture group and the model or non-point acupuncture group after different times of cerebral ischemia/reperfusion (P<0.05).Conclusions Acupuncture can inhibit the overexpression of Cx43, intervene in cerebral ischemia-reperfusion injury and produce a neuroprotective effect in ischemic brain injury.

Objective To explore the effects of accumulated 60CD,γ-ray irradiation on small molecular metabolites in rats urine.Methods Ten healthy male SD rats were irradiated by 60Co γ-rays in 5 days and the accumulated doses were 0,0.2,0.4,0.6,0.8,1.0 Gy,respectively.The metabolites in urine of different groups were measured with 1 H-NMR combined with principal components analysis (PCA) and partial least square discriminate analysis (PLS-DA). Results The metabolites in rat urine were obviously changed after irradiation. Compared with control group,the amount of acetoacetate decreased after irradiation(t =29.7 -30.7,P ＜ 0.05 ),but its relative level was stable when the dose increased ( P ＞ 0.05 ).Meanwhile,the relative level of hippuric acid increased ( t =4.4 - 21.6,P ＜ 0.05 ) especially when the accumulated dose was higher than 1 Gy (t =21.6,P＜0.05). The relative level of proline,taurine and trimethylamine-N-oxide increased after irradiation with the same trend( t =3.5 - 13.4,4.7 - 11.5,2.9- 12.7,P＜0.05). Conclusions The acetoacetate,hippuric acid,proline,taurine,and trimethylamine-N-oxide may be applicable for biomarkers of accumulative irradiation on rat.

Objective To investigate the effect of POSTN protein on the proliferation of chondrocytes of tibial plateau in old rats.Methods Cartilage cells collected from the tibial plateau of old rats were cultured in vitro to the third generation.Then the cells were divided into 3 groups:POSTN group,PBS group and POSTN antibody group.The proliferations of the three groups at 24 h,48 h and 72 h were determined by EDU method.The expression of Notch1 protein was detected by immunohistochemistry in all groups at the same time.Female 20-month-old Sprague-Dawley rats were randomly divided into 3 groups:POSTN protein injection group,Phosphate Buffered Saline (PBS) injection group and POSTN antibody injection group.Twelve weeks after the operation,related reagents were injected 3 times consecutively at day 1,day 3,day 5 and EDU was injected into joints at day 1.At 2 weeks after injection,the rats were killed and the knee tibial plateau was taken to observe the proliferation of the cartilage cells.Results At 24 h,there were differences between the three groups O(F=27.32,P=0.017).The proliferation rates of POSTN group [(23±8)％] and PBS group [(21±10)％] were higher than that of POSTN antibody group (16±5)(P=0.003,P=0.011).At 48 h,there were differences between the three groups (F=35.34,P＜0.01).The proliferation rate of POSTN group [(36±11)％] was higher than that of the other groups [(22±6)％],(18±6)％(P=0.021,P＜0.01).At 72h,there were differences between the three groups (F=52.62,P=0.000).The proliferation rate of POSTN group [(56±17)％] was the highest one,the proliferation rate of PBS group [(31±8)％] was the medium,and the POSTN antibody group [(26±7)％] was the lowest one (all P＜0.05).As for Notch1 protein expression in chondrocytes,there were differences between the three groups (F=26.72,P＜0.01).The Notch1 protein was the most frequently expressed in POSTN protein-injection group and the least in the anti-POSTN group.In rats,the proliferation rate of the chondrocytes in the medial tibia plateau of the knee of POSTN protein injection group [(36±14)％],which was the highest,and that of the POSTN antibody injection group [(10 ±4)％] was the lowest (all P＜0.05).Conclusion POSTN protein can promote the proliferation of chondrocytes knee OA rats.POSTN antibody injection has been shown to induce the proliferation of chondrocytes.The POSTN protein may promote the proliferation of chondrocytes by activating the Notch signaling pathway.

Three new sesquiterpene glycosides, named codonopsesquilosides A-C (1-3), were isolated from an aqueous extract of the dried roots of Codonopsis pilosula. Their structures including absolute configurations were determined by spectroscopic and chemical methods. These glycosides are categorized as C15 carotenoid (1), gymnomitrane (2), and eudesmane (3) types of sesquiterpenoids, respectively. Compound 1 is the first diglycoside of C15 carotenoids to be reported. Compound 2 represents the second reported example of gymnomitrane-type sesquiterpenoids from higher plants. The absolute configurations were supported by comparison of the experimental circular dichroism (CD) spectra with the calculated electronic CD (ECD) spectra of 1-3, their aglycones, and model compounds based on quantum-mechanical time-dependent density functional theory. The influences of the glycosyls on the calculated ECD spectra of the glycosidic sesquiterpenoids, as well as some nomenclature and descriptive problems with gymnomitrane-type sesquiterpenoids are discussed.
