Objective To investigate the insulin resistance and microalbuminuria in the healthy offspring with a family history of essential hypertension,in order to explore the relationship between the genetic factor and early renal injury.Methods 69 healthy offsprings with the family history of essential hypertension were randomly recruited as the observation group,35 healthy offsprings without the family history of essential hypertension were considered as the control group.The consecutive 12-hour urine was collected to detect the urinary albumin,and blood biochemical examination was conducted.Results Plasma levels of triglyceride (TG),total cholesterol (TC),glucose,fasting insulin,and urinary albumin excretion rate were higher in observation group than in the control group [(1.07±0.65) mmol/L vs.(0.79±0.52) mmol/L,(4.83±0.78) mmol/L vs.(4.48±0.63) mmol/L,(5.27±0.73) mmol/L vs.(4.94±0.85) mmol/L,(10.63±3.21) mIU/L vs.(7.72±3.35) mIU/L,(45.6±29.5) μg/min vs.(18.6±11.7) μg/min,t=2.259、2.348、2.093、4.381、5.337,all P＜0.05].Conclusions Insulin resistance and microalbuminuria occur before hypertension in healthy offsprings with the family history of essential hypertension,and the patients are prone to getting early renal damage,which indicates that heredity is a risk factor for chronic kidney disease.

TFL1 homologs play important roles in maintaining vegetative growth and inflorescence meristem identity. The plants without the function of this gene usually are flowering earlier. Their normal inflorescence development is inhibited, the inflorescence meristem eventually acquired floral identity, which producing a terminal flower. Up to now, the TFL1 homologs have been isolated from 28 species of plants, including Arabidopsis, Snapdrogen and Tomato. The phylogenic tree of TFL1 proteins is almost accordance with the relative of those plants. The inflorescence identity gene TFL1 interacted with floral meristem identity genes LFY and AP1, so as to retard the transformation from inflorescence identity into floral identity. These meristem identity genes such as TFL1 and LFY can be applied in breeding of earl-flowering cultivars, there also have plenty of potentials in breeding fruit-free plantanus, popular or willows.

Objective To observe the effect of triptolide on destruction of bone and joint of collageninduced arthritis (CIA) mouse. Methods Female DBA/1 mice were double immunized at the base of the tail with bovine type Ⅱ collagen (C Ⅱ). CIA mice were randomly divided into model group, methotrexate-treated group and 8.18, 16.36, 32.72 ?g/kg triptolide-treated groups. Performance of arthritis were observed regularly. Combined with radiologieal, histological methods were used, and the number of osteoelasts in bone was evaluated and analyzed with TRAP stainning. Results The clinical score and arthritis incidence of CIA mice were significantly decreased, and the number of osteoelasts in bone cavity reduced by treatment of triptolide. X-ray showed that the surface of bone of each articular was eroded, the joint space was narrow, BMD values of lumbar and knee were decreased compared with normal mice. Triptolide could significantly inhibit the damage of bones and joints of CIA mice, and increase the BMD values of lumbar and knee. Conclusion Triptolide can inhibit the damage of bones and joints of CIA mice.

Objective To evaluate the effect of isoflurane anesthesia on noise-induced hearing loss in guinea pigs.Methods Forty-eight healthy adult male guinea pigs,aged 3 months,weighing 400-500 g,were randomly divided into 4 groups (n =12 each) using a random number table:control group (C group),isoflurane group (I group),noise-induced hearing loss group (N group),and isoflurane + noise-induced hearing loss group (I + N group).Isoflurane was inhaled for 140 min at a concentration of 1％ in I and I + N groups.N and I + N groups were exposed to the noise of 4 kHz center frequency and 118-122 dB sound pressure level for 120 min starting from 20 min after administration.Mean arterial pressure (MAP) was recorded at 10,40,70,100 and 120 min of exposure to noise and cochlear blood flow (CoBF) was recorded before administration and at 10,40,70,100 and 120 min of exposure to noise.Auditory brainstem response (ABR) threshold was recorded before administration and at 1 h,72 h,and 10 days after the end of exposure to noise.Arterial blood samples were obtained and the plasma noradrenaline (NE) concentration was detected by HPLC before exposure to noise and immediately after the end of exposure to noise.Results Compared with group C,MAP and the change rate of CoBF were significantly decreased,and the plasma NE concentration was increased immediately after the end of exposure to noise in I group,and MAP was increased,the change rate of CoBF was decreased,and the plasma NE concentration immediately after the end of exposure,and ABR threshold after the end of exposure were increased in N and I + N groups.Compared with N group,MAP was significantly decreased,the change rate of CoBF was increased,the plasma NE concentration immediately after the end of exposure,and ABR threshold at 1 and 72 h after the end of exposure were increased,and no significant was found in ABR threshold at 10 days after the end of exposure in I + N group.Conclusion Isoflurane anesthesia exerts temporary but not permanent protective effects against noise-induced hearing loss in guinea pigs and partial inhibition of activation of sympathetic nerve and increased CoBF may be involved in the mechanism.

Objective To study the effects of 1,25-(OH)_2-vitamin D_3[1,25-(OH)_2D_3] on proliferation,differentiation, and secretion of osteoprotegerin and RANK ligand (RANKL)in cultured marrow mesenchymal cells of rhesus monkey (RhBMSCs). Methods Three different concentrations of 1,25-(OH)_2D_3 (10~(-12) ,10~(-10), and 10~(-8)mol/L)were added to the cultured RhBMSCs in vitro. MTT was used to observe cell proliferation and ELISA technique was used to measure the concentration of alkaline phosphatase (ALP), osteocalcin, osteoprotegerin, and RANKL. Mineralization nodus was identified via alizarin red staining. Results Under different concentration of 1,25-(OH)_2D_3, RhBMSCs proliferation were promoted within 7 days but were suppressed beyond 7 days. No significant dose-dependent manner was found. Differentiation of RhBMSCs into osteoblast was promoted by 1,25-(OH)_2D_3. The levels of ALP and osteocalcin in groups with various concentrations of 1,25-(OH)_2D_3 were higher than those of control group [ALP(ng/ml) ,7 d:31.40±1.25,26.50±0.50,28.47± 0.25 vs 13.48±0.26;10 d:33.37±0.68,35.30±1.57,33.27±0.67 vs 17.14±0.55;13 d:35.37±0.12,30.47± 0. 25 , 30. 27±1.25 vs 16.55 ± 1.13 ; osteocalcin (ng/ml), 7 d:4.47±0. 29,4.00 ±0. 60,3.73±0.78 vs 1.63± 0.55;10 d:5.63±0.57,5.17±0.15,4.30±0. 10 vs 2.17±0. 15;13 d:7.03±0.15,5.53±0.25,5.27±0.31 vs 2.23±0. 55 ; all P < 0. 05], but no typical mineralization nodus was found in either group. Secretions of osteoprotegerin and RANKL from RhBMSCs were stimulated by 1,25-(OH)_2D_3 [osteoprotegerin (pg/ml), 7 d: 72.57±0.67,68.00±1.75,64.23±0.87 vs 30. 13±1.72; 10 d:62.03±1.62,51.80±1.30,28.93±0.95 vs 18.13±1.40;13 d:65.13±0.71,62.43±2.11,44.93+1.63 vs 36.70±0.95 ;RANKL(pg/ml) ,7 d:74.33+0.61, 82.37±2.15,85.23±0.45 vs 70.83±1.71 ;10 d:83.30±0.46,86.70±0.56,88.23±0.91 vs 74.20±1.83;13 d: 81.70±1.81,81.07±0.95,84.70±1.41 vs 72.73±0.97 ;all P<0.05]. The secretion of RANKL was increased at first and then decreased, whereas the secretion of osteoprotegerin had the opposite tendency. The secretions of RANKL and osteoprotegerin were both in a dose-dependent manner. Conclusions 1,25-(OH)_2D_3 promotes differentiation of RhBMSCs into osteoblasts,resulting in increased secretions of osteoprotegerin and RANKL

Objective To analyze the incidence,risk factors,clinical characteristics and pregnant outcomes of perinatal pulmonary embolism(PPE).Methods Clinical data of eight patients who were admitted to Beijing Friendship Hospital of Capital Medical University for PPE from January 2006 to March 2016 were collected.General condition,symptoms,laboratory examinations,images,treatments and outcomes of these patients were analyzed retrospectively.Results The ten-year incidence of PPE was 0.029％ (8/27 560) in this hospital.Among the eight cases,two cases were diagnosed in the first trimester,and treated successfully by thrombolytic therapy.But one of two cases stopped growth,while the other one was premature labor.There were one case in the third trimester who had successful anticoagulant therapy and five cases in the postpartum period after cesarean delivery.Among the five cases,three cases were recovered after anticoagulant therapy,one case was recovered after thrombolytic therapy and one case died.All of the eight patients were immobilized before the onset of PPE,and five of them were diagnosed after cesarean section.Four out of the eight patients were obese.Five patients had three or more high-risk factors for pulmonary embolism and the other three had two.Conclusions It is necessary to pay close attention to gravidas who have two or more high-risk factors of PPE due to its fatal outcome.

Objective: To investigate the changing trends in the burden of cardiovascular diseases (CVD) in Zhejiang Province from 1990 to 2019, so as to provide insights into CVD control in the province. Methods: Based on the data of the Global Burden of Disease Study (GBD) 2019 (GBD 2019), the years lived with disability (YLD), years of life lost (YLL), disability-adjusted life years (DALY), YLD rate, YLL rate and DALY rate due to CVD were estimated to assess the burden of CVD in Zhejiang Province from 1990 to 2019. The changing trends in the burden of CVD were using annual percent change (APC) in Zhejiang Province from 1990 to 2019, and compared to China and global regions with different socio-demographic indexes (SDI). Results: The YLL rate (APC=-0.50%, F=22.366, P<0.001) and DALY rate due to CVD (APC=-0.20%, F=5.212, P=0.030) appeared a tendency towards a decline in Zhejiang Province from 1990 to 2019, while the YLD rate showed a tendency towards a rise (APC=1.92%, F=1 117.891, P<0.001). The YLL rate (APC=-1.09%, F=56.871, P<0.001), YLD rate (APC=1.92%, F=922.541, P<0.001) and DALY rate (APC=-0.60%, F=28.974, P<0.001) appeared the same tendency among women relative to among the whole populations, while only the YLD rate showed a clear-cut change among men, appearing a tendency towards a rise (APC=1.82%, F=1 238.423, P<0.001). Both the YLL rate and DALY rate appeared a tendency towards a decline among subjects at all age groups, with the most significant reduction among subjects at ages of 50 to 69 years (YLL rate: APC=-4.40%, F=1 443.608, P<0.001; DALY rate: APC=-3.82%, F=1 519.452, P<0.001). Among all types of CVD, the highest burden was measured in cerebrovascular diseases, with a standardized DALY rate of 1 359.7/105, and the most remarkable reduction in the standardized DALY rate was seen in rheumatic heart diseases. The burden of CVD in Zhejiang Province was lower than that in China and the majority of the world, with consistent changing trends with that in China and global regions with different SDI. Conclusions The overall burden of CVD appeared a tendency towards a decline in Zhejiang Province from 1990 to 2019, which was in agreement with that in China and global regions with different SDI. A remarkable reduction in the burden of CVD was seen among women, residents at ages of 50 to 69 years and cases with rheumatic heart diseases.
