To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.

Objective To observe the expression of STEAP4 gene(a novel obesity-related gene) during the period of human preadipocyte differentiation and to explore the relationship between the STEAP4 gene expression and adipocytes differentiation,adipogenesis.Methods Human preadipocytes were cultured and differentiated into the matured adipocytes in vitro.Adipocytes morphology and lipid accumulation were observed during this process.Total RNA was extracted from adipocytes at various time points (preadipocyte,Day 0,Day 4,Day 6,Day 8,Day 11,Day 14,and Day 17) and the level of STEAP4 mRNA expression was measured by fluorescent real-time quantitative reverse transcriptase-polyme-rase chain reaction(RT-PCR).Results The level of STEAP4 mRNA expression remained high in preadipocytes.In the presence of differentiation medium (Day 4),there was a transient upregulation in the expression of STEAP4 gene.After that,with the human preadipocytes being differentiated into matured adipocytes,the expression of STEAP4 mRNA was downregulated and reached the lowest level in fully differentiated adipocytes.There was a significant difference between any 2 detected phases in the level of STEAP4 mRNA expression (Pa

OBJECTIVETo study the effects of angiotensin II receptor blockers (ARB), losartan and irbesartan, on blood pressure and serum uric acid (SUA) level in mild to moderate essential hypertensive patients complicating hyperuricaemia.

METHODSA total of 351 eligible patients were recruited in this multi-center, randomized, double-blind parallel clinical trial. After 1 week screening and a 2 week single-blinded placebo wash-out period, patients were randomly assigned to receive losartan 50 mg (n=76) or irbesartan 150 mg (n=175) once daily for 4 weeks, followed by a double-dose for another 4 weeks in patients whose seated DBP were >or=90 mm Hg or SBP>or=140 mm Hg at the end of 4 weeks. The SUA concentration and blood pressure were measured at baseline, 4 and 8 weeks post therapy.

RESULTSThree hundred and twenty-five patients completed the study (162 in the losartan group and 163 in the irbesartan group). Both groups were well matched for baseline clinical characteristics and demographics. SUA was significant reduced in losartan group (430.93 micromol/L vs 372.35 micromol/L, P<0.0001), but not in Irbesartan group (430.46 micromol/L vs 420.67 micromol/L, P>0.05) 8 weeks post therapy compared to baseline level. Blood pressure was significantly and equally reduced in both groups after 8 weeks treatment compared to baseline level (P<0.0001).

CONCLUSIONLosartan is an optimum choice of medication for patients with mild-to-moderate hypertension complicating hyperuricemia.

OBJECTIVE: To analyze the clinical and genetic characteristics of three Chinese pedigrees affected with Citrullinemia type I (CTLN1). METHODS: Three children diagnosed at the Children's Hospital Affiliated to Shandong University from 2017 to 2020 were selected as the study subjects. Genomic DNA was extracted from peripheral blood samples of the probands and their parents. Next generation sequencing (NGS) was carried out to detect pathological variants of the probands. Sanger sequencing was used for validating the candidate variant among the pedigrees. RESULTS: The probands have respectively carried compound heterozygous variants of c.207_209delGGA and c.1168G>A, c.349G>A and c.364-1G>A, c.470G>A and c.970G>A of the ASS1 gene, which were respectively inherited from their parents. CONCLUSION The newly discovered c.207_209delGGA and c.364-1G>A variants have enriched the mutational spectrum of the ASS1 gene. And the mutation spectrum of Chinese CTLN1 patients is heterogeneous.

OBJECTIVEHuman STEAP4, a novel obesity-related gene, is associated with insulin sensitivity regulation in human adipocytes. This study aimed to explore the regulative role of TNFalpha on STEAP4 gene in matured human adipocytes.

METHODSHuman preadipocytes were cultured and differentiated into matured adipocytes in vitro. Fully differentiated adipocytes (Day 17) were treated with different concentrations of TNFalpha (0, 5, 10, 25 and 50 ng/mL) for 24 hrs. Total RNA and protein were extracted from the adipocytes. Levels of STEAP4 mRNA and protein expression were determined by real-time quantitative RT-PCR and Western blot respectively.

RESULTSDifferent concentrations (5, 10, 25 and 50 ng/mL) of TNFalpha treatment for 24 hrs resulted in a significant increase in the STEAP4 mRNA expression of human matured adipocytes.The maximal effect was seen in the 50 ng/mL of TNFalpha treatment group. In parallel, STEAP4 protein synthesis in matured adipocytes increased in response to TNFalpha treatment of different concentrations (5, 10, 25 and 50 ng/mL) for 24 hrs. The maximal up-regulated effect was seen in the 25 ng/mL of TNFalpha treatment group.

CONCLUSIONSTNFalpha can up-regulate STEAP4 mRNA expression in human matured adipocytes.

Extracellular matrix (ECM) stiffness is closely related to the physiological and pathological states of breast tissue. The current study was aimed to investigate the effect of silk fibroin/collagen composite hydrogels with adjustable matrix stiffness on the growth and phenotype of normal breast epithelial cells. In this study, the enzymatic reaction of horseradish peroxidase (HRP) with hydrogen peroxide (H₂O₂) was used to change the degree of cross-linking of the silk fibroin solution. The rotational rheometer was used to characterize the composite hydrogel's biomechanical properties. Human normal mammary epithelial cell line MCF-10A were inoculated into composite hydrogels with various stiffness (19.10-4 932.36 Pa) to construct a three dimensional (3D) culture system of mammary epithelial cells. The CCK-8 assay was applied to detect the cell proliferation rate and active states in each group. Hematoxylin-Eosin (HE) staining and whole-mount magenta staining were used for histological evaluation of cell morphology and distribution. The results showed that with the increase of matrix stiffness, MCF-10A cells exhibited inhibited proliferation rate, decreased formation of acinus structures and increased branching structures. Meanwhile, with the increase of matrix stiffness, the polarity of MCF-10A cells was impeded. And the increase of matrix stiffness up-regulated the expression levels of mmp-2, mmp-3, and mmp-9 in MCF-10A cells. Among the genes related to epithelial-mesenchymal transition (EMT), the expression level of the epithelial marker gene E-cadherin was significantly down-regulated, while the interstitial cell marker gene Vimentin was up-regulated, and the expression levels of Snail, Wnt5b and Integrin β1 in the Wnt pathway were up-regulated. These results suggest that the silk fibroin/collagen composite hydrogels with adjustable matrix stiffness regulates the proliferation and the phenotype of MCF-10A cells. The effects of increased matrix stiffness may be closely related to the changes of the polar structures and function of MCF-10A cells, as well as the occurrence of ECM-remodeling and EMT.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.

METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).

RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).

CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.

BACKGROUNDAmbient aerosol fine particulate matter (PM2.5) is associated with male reproductive toxicity in experiments and may have adverse effects in the female. However, studies evaluating the protective effects and precise mechanisms of aspirin, Vitamin C, Vitamin E, or ozone against toxic effects of PM2.5are sparse. This study was conducted to investigate the possible protective effects and mechanisms of aspirin, Vitamin C, Vitamin E, or ozone on fertility in female mice treated with PM2.5.

METHODSEighty-four ICR mice were divided into six groups: control group, PM2.5group, PM2.5 + aspirin group, PM2.5 + Vitamin C group, PM2.5 + Vitamin E group, and PM2.5 + ozone group. PM2.5was given by intratracheal instillation every 2 days for 3 weeks. Aspirin, Vitamin C, and Vitamin E were given once a day by oral gavage for 3 weeks, and ozone was administered by intraperitoneal injection once a day for 3 weeks. The levels of anti-Müllerian hormone (AMH), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were measured using enzyme-linked immunosorbent assay. Western blotting analysis was used to analyze the expressions of Bcl-2, Bax, and caspase-3 in ovaries. Changes in histological structure were examined by light microscope and electron microscopy was used to detect ultramicrostructure.

RESULTSThe results demonstrated that PM2.5 decreased AMH levels (P < 0.001); however, aspirin (P < 0.001), Vitamin C (P < 0.001), Vitamin E (P = 0.001), and ozone (P = 0.002) alleviated the decrease. Changes of IL-6, TNF-α, 8-OHdG, Bax/Bcl-2, and caspase-3 in PM2.5group were increased compared to control group (P < 0.001), while in PM2.5 + aspirin, PM2.5 + Vitamin C, PM2.5 + Vitamin E, and PM2.5 + ozone groups, they were statistically decreased compared to PM2.5group (P < 0.001 or P< 0.05).

CONCLUSIONSPM2.5cause the damage of ovaries, and aspirin, Vitamin C, Vitamin E, and ozone antagonizes the damage. The protective mechanism is probably due to its ability to blunt the inflammatory and oxidative stress caused by PM2.5, which subsequently suppressing the expression of apoptotic regulatory protein and reducing the incidence of ovary apoptosis.

Colla Corii Asini(Ejiao)is an important Chinese medicine used in China for thousands of years, and is well known for its famous tonic properties. The herbalogical study was detailed carried out based on the naming, habitat, harvesting, processing, medicinal properties and clinical efficacy. The results showed that the name of Ejiao could be traced back to Shennong's Materia Medica, and various names of Lvpi Jiao, Penfu Jiao and Fuzhi Jiao were recorded in other ancient books. In the many intervening centuries, the main materials of Ejiao had been replaced from cow leather before Tang Dynasty to donkey skin in the middle to late Tang Dynasty. This phenomenon could be probably caused by complicated social factors of various periods and different efficacy of Ejiao made by all kinds of raw materials. Ejiao was merely processed with the simple methods before Tang Dynasty, which subsequently improved avariety of methods to enhance the supplementation action. Most importantly, Ejiao has a wide clinic application along with the development of processing theories and methods, which can be found in various Classics, especially in imperial medical case record in Qing Dynasty.
