BACKGROUND: Angiogenesis in atherosclerotic plaque occurred on the basis of atherosclerotic lesions, and the new formed blood vessels promoted the development of angiogenesis. Soluble vascular endothelial growth factor receptor 1 (sFlt-1) gene transfection reduces neointimal formation after vascular injury in rabbits, also reduces early vascular inflammation and proliferation, and the formation of neointima lately.
OBJECTIVE: To observe the effects of highly expressed sFlt-1 on atherosclerotic plaque.
METHODS: A total of 48 male New Zealand rabbits were divided into four groups randomly: normal control group (n=8), sham operation group (n=8), bal oon injury+high lipid diet+pEGFP-N1 group (n=16) and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group (n=16). Normal control group and sham operation group were supplied with normal diet. Bal oon injury+high lipid diet+pEGFP-N1 group and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group were supplied with high lipid diet and injured by bal oon 2 weeks later. Bal oon injury+high lipid diet+pEGFP-N1 group was transfected with pEGFP-N1 and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group was transfected with pEGFP-N1-sFlt-1.
RESULTS AND CONCLUSION: In the bal oon injury+high lipid diet+pEGFP-N1 group and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group, blood lipid levels apparently increased. At 3 days after model establishment, sFlt-1 expression levels noticeably increased, and atherosclerotic plaque formed to different degrees. Plaque area, plaque perimeter, plaque maximum thickness and the number of positive-cel s within the plaque were significantly less in the bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group than in the bal oon injury+high lipid diet+pEGFP-N1 group. These results confirm that sFlt-1 gene may express effectively in iliac artery wal of rabbit, inhibited the formation of atherosclerotic plaque and delayed the development of atherosclerotic plaque.

OBJECTIVE:To observe clinical efficacy and safety of Bushen sanhan tongluo decoction combined with moxi-bustion and celecoxib in the treatment of knee osteoarthritis (KOA). METHODS:A total of 70 KOA patients were selected from Chongqing Kanghua Hospital during May 2014-Dec. 2015,and then divided into observation group and control group ac-cording to odd and even number,with 35 cases in each group. Control group was given Celecoxib capsule 0.2 g,qd;observa-tion group was additionally given Bushen sanhan tongluo decoction(one dose a day,300 mL,decocted with water,taking it 3 times in the morning,noon and night)and moxibustion. A treatment course lasted for 4 weeks,and both received 2 courses of treatment. Clinical efficacies as well as TCM syndrome score,VAS score,WOMAC score,lab indexes,joint condition be-fore and after treatment,the occurrence of ADR were compared between 2 groups. RESULTS:Total response rate of observa-tion group (85.71％) was significantly higher than control group (68.57％),with statistical significance (P<0.05). Before treatment,there was no statistical significance in above indexes between 2 groups (P>0.05). After treatment,TCM syn-drome score,VAS score,WOMAC score,erythrocyte sedimentation rate,CRP level and knee swelling score of 2 groups were decreased significantly,compared to before treatment;those indexes of observation group were significantly lower than those of control group,with statistical significance(P<0.05). There was no statistical significance in the number of bone fric-ative joint between 2 groups before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR (5.71％ vs. 2.86％) between 2 groups (P>0.05). CONCLUSIONS:Bushen sanhan tongluo decoction combined with moxibustion and celecoxib can improve clinical symptoms,relieve joint pain,joint inflammation and swelling of KOA pa-tients with good safety.

Objective To investigate the effects of maternal long-term exposure to low-dose trichlorfon on the serum paraoxonase (PON) activity of pregnant mice and development of embryos. Methods Female ICR mice (n=120) were randomly divided into control group and trichlorfon groups of different doses,and were managed by intragastric injection with trichlorfon of 0,2,10 and 50mg/kg,respectively. All the mice were managed once a day for a consecutive of 27 days,and were subjected to mating. The pregnant mice were continued to be managed with trichlorfon for 3 days,and were sacrificed on day 3 of gestation. The serum PON and acetylcholinesterase (AchE) activities were detected,and the development of embryos was evaluated. Results The serum PON activity of 2,10 and 50mg/kg trichlorfon group were (14.15?1.22),(12.78?1.80) and (10.45?1.95)IU/mL,respectively,and that of 50mg/kg trichlorfon group was significantly lower than that of control group [(13.37?2.31)IU/mL] (P0.05),while the the percentage of abnormal embryos of 50mg/kg trichlorfon group had an increased tendency. Conclusion Long-term exposure to low-dose trichlorfon can inhibit serum PON and AchE activity in pregnant mice without obvious effect on the development of embryos.

Due to the low effectiveness of traditional assisted reproductive technology (ART), new technological possibilities are constantly explored. Lots of studies have demonstrated the potential of microfluidics to revolutionize the fundamental processes of in vitro fertilization (IVF). With the advantages of high efficiency, short time, harmless collection, real-time observation of separation, similar microenvironment, and automation, the application of microfluidics in sperm isolation and IVF has shown an evident superiority over the conventional approaches and provided a new platform for ART. This review highlights the application of various microfluidic techniques in sperm motility assessment and isolation, sperm chemotaxis assay, IVF, sperm concentration, and sperm separation and enrichment in recent years. It also briefly introduces the basic principles, structural design, and operation processes of the microfluidic platform, focusing on the advantages and disadvantages of each method and the potential of their clinical application. Obviously, there are still some challenges to the application of microfluidics in ART. However, it is believed that the development of this new technology would be toward a highly integrated application of several steps in one single device, known as IVF-lab-on-a-chip.

Objective: To investigate the genotypes and prognosis of infants with definitive diagnosis of inherited metabolic diseases during neonatal screening in Zhejiang Province from 2009 to 2021, so as to provide insights into the management of birth defects. Methods: The medical records of infants with definitive diagnosis of inherited metabolic diseases by tandem mass spectrometry during neonatal screening in Zhejiang Province from 2009 to 2021 were collected from the database created by Zhejiang Provincial Center for Neonatal Disease Screening. The prevalence, genotypes and prognosis of inherited metabolic diseases were analyzed. Results: A total of 1 038 infants were definitively diagnosed with inherited metabolic diseases in Zhejiang Province from 2009 to 2021, with an overall incidence rate of 1/4 535. There were 400 infants with amino acid metabolic disorders (AAD), 342 infants with fatty acid oxidation metabolic disorders and 296 infants with organic acid metabolic disorders (OAD), with incidence of 1/11 767, 1/13 763 and 1\15 902, respectively. There were 32 types of diseases, including 13 types of AAD, 8 types of FAOD and 11 types of OAD identified, and phenylketonuria and tetrahydrobiopterin deficiency (PKU/BH4D), primary carnitine deficiency (PCD) and methylmalonic academia (MMA) were detected as the most common forms of AAD, FAOD and OAD, with incidence of 1/20 827, 1/24 262 and 1\49 030, respectively. A total of 789 infants received genetic testing (76.01%), and genetic testing was performed among 70.00% of infants with AAD, 83.04% of infants with FAOD and 76.01% of infants with OAD. The c.728G >A (p.R243Q) variant was the most common mutation in infants with PKU (29.17%), c.1400C>G (p.S467C) variant was the most common mutation in infants with PCD (33.46%), c.609G>A (p.W203X) variant was the most common mutation in infants with combined MMA (40.00%), and c.1663G>A (p.A555T) variant was the most common mutation in infants with MMA (17.86%). Among the 997 infants (96.05%) with successful follow-up, 973 infants (93.74%) had normal intelligence and physical developments, and 41 infants died (3.95%), including 9 deaths due to AAD, 15 deaths due to FAOD and 17 deaths due to OAD. Conclusions The incidence of PKU, PCD and MMA was high among infants with inherited metabolic diseases in Zhejiang Province from 2009 to 2021, with c.728G>A (p.R243Q), c.1400C>G (p.S467C) and c.609G>A (p.W203X) variants as common gene mutations, respectively. Most infants with inherited metabolic diseases had a favorable prognosis; however, the mortality of OAD was relatively high.
