Objective:To explore the efficacy of nimodipine in treating cognitive impairment of cerebral small vessel disease (CSVD) and the value of magnetic resonance diffusion tensor imaging (DTI) in CSVD.Methods:A total of 80 patients with CVSD and cognitive dysfunction who admitted to Suzhou Municipal Hospital from February 2018 to February 2019 were selected, and the patients were divided into control group (40 patiengts) and observation group (40 patients) by random number table method. The control group received basic treatment and donepezil, and the observation group added nimodipine on the basis of control group. All patients were followed up for 12 months. Before treatment, 6 months after treatment and 12 months after treatment, the patients’Montreal cognitive assessment scale (MoCA) score, daily living ability scale (ADL) score, and Tinetti balance and gait analysis(TGA) were recorded. The levels of total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), homocysteine (Hcy) and high-sensitivity C-reactive protein (hs-CRP) before and after treatment were recorded. The changes of DTI data before and after 12 months′ treatment in the two groups were recorded.Results:The MoCA score, ADL score, and TGA score of the two groups were higher than those before treatment and at 6 months and 12 months after treatment, and those 12 months after treatment were higher than those at 6 months after treatment. There were significant differences ( P<0.05). The MoCA and ADL scores of the observation group were higher than those of the control group at 6 and 12 months after treatment at 6 months: (24.61 ± 2.54) scores vs. (22.21 ± 2.83) scores, (71.53 ± 6.25) scores vs. ( 69.51 ± 6.81) scores; 12 months: (26.39 ± 2.16) scores vs. (23.76 ± 2.64) scores, (78.39 ± 5.76) scores vs. (72.39 ± 6.12) scores, P<0.05. At 6 months and 12 months after treatment, the visual space and execution ability, delayed memory, and orientation scores were higher than those before treatment, and in the observation group 12 months after treatment was higher than those 6 months after treatment: (5.97 ± 1.37) scores vs. (5.36 ± 1.29) scores, P<0.05. The observation group′s visual space and executive ability, abstract thinking, delayed memory, and orientation score were higher than those in the control group at the same period ( P<0.05). The levels of TC, TG, LDL-C, Hcy and hs-CRP of the two groups after treatment for 6 and 12 months were lower than those before treatment, and the levels of these index at 12 months after treatment were lower than those at 6 months after treatment ( P<0.05). The levels of Hcy and hs-CRP in the observation group were lower than those in the control group at 12 months after treatment, and Hcy was lower than that in the control group at 6 months after treatment ( P<0.05). After treatment, the fractional anisotropy (FA) values of the center, frontal lobe, and parietal lobe of both sides of the two groups were higher than those before treatment, and the difference in the observation group before and after treatment was higher than that of the control group ( P<0.05). After treatment, the mean diffusivity (MD) values of both frontal lobe and parietal lobe of the two groups were lower than those before treatment, and the difference between the observation group before and after treatment was higher than that of the control group ( P<0.05). Conclusions:Nimodipine has a good effect on the treatment of CVSD, which can effectively improve the patients′ cognitive impairment and other symptoms. DTI can sensitively sense the white matter integrity and cerebral blood flow perfusion of patients, which has a positive significance for the prevention and treatment of CVSD.

Objective To investigate the effects of oestrogen-receptor(ER), progesterone-receptor(PR), vascular endothelial growth factor(VEGF) and kinase insert domaincontaining receptor(KDR) in uterine bleeding induced by intrauterine device(IUD). Methods Immunohistochemical method was used to detect the expressions of ER, PR, VEGF and KDR in endometrium from IUD bleeding group and normal control group, respectively. Microvessel density(MVD) was evaluated by using anti factor Ⅷ-related antigen (F8-RA) antibody to mark stromal microvessels. Results The expressions of ER, VEGF and KDR were significantly higher in IUD-induced endometrium bleeding group than those in control group(P0.05). MVD was significantly higher in IUD-induced endometrium bleeding than that in normal endometrium(P

Objective To establish a HPLC method for the determination of quercetin from different parts of L. cuncata(Dum. Cours.)G.Don.,including roots,old branches,young shoots,leaves and seeds,and to build the fingerprints. Methods The HPLC method determination of quercetin and fingerpints were establised. Results The restults showed that there were great differences be?tween the quercetin contents from different parts,with the highest contents found in seeds,followed by young shoots,leaves,old branches,and roots. The similarities of HPLC fingerprints of the medicinal material were quite different from the parts of L. cuncata (Dum.Cours.)G.Don.. The similarities were all above 0.95 for L. cuncata(Dum.Cours.)G.Don. samples,roots,old branches and young shoots below 0.85,leaves and seeds similarities below 0.60. Conclusion It was concluded that different parts(such as roots, old branches,young shoots,leaves,seeds)of L. cuncata(Dum.Cours.)G.Don. should be divided in clinical and productive practice so as to supply the scientific basis for enhancing the curative effect and reasonable utilization of the resource of L. cuncata(Dum.Cours.)G. Don.

The somatostatin analogue pasireotide is a new type of protein which is the first therapeutic agent targeted to the pituitary.Pasireotide can prevent adrenocorticotropic hormone release and inhibit the growth of tumor cells after coupling with somatostatin receptor of the target cell membranes.Pasireotide has a high binding affinity for most of somatostatin receptor (SSTR) subtypes and in particular for SSTR5.Pasireotide can paly an important role in the new round of new targets for individualized diagnosis and treatment of tumors through the studies of translational medicine.

An angular speed, acceleration and tangential leakage of a synchronal rotary compressor in which both bladed rotor and a cylinder are discussed. The calculation formulae of revolving speed of cylinder and relative speed between the cylinder and bladed rotor are deduced detailedly in this paper. The variation of tangential speed and cylinder acceleration with angular position is investigated for a complete cycle. And some key parameters affected the relative speed are found out, viz, the relative speed depends on the radius of the cylinder and rotary speed of the axis, and the ratio of the cylinder to bladed rotor has not too much influence. It is the theoretic basis of designing and optimizing of structure characteristic of a synchronal rotary compressor. Also a computing formula of leakage related with rotary speed is deduced. It could supply

Objective To investigate the distribution modes of NOS nerves and interstitial cells of Cajal (ICCs) in myenteric plexus of human fetal intestine. Methods Small intestine samples from 12 fetuses were collected for the preparation of whole mount preparations and cryo sections examined by immunocytochemistry for c kit receptor tyrosine kinase and histochemistry for NADPH diaphorase. Results ICCs associated with the myenteric plexus in the fetal small intestine were observed in the shape of spindle or ovoid with two to three slender processes forming an independent and complete cellular network. While NOS positive nerves, which constitute the main neuronal component of ganglia, connecting strands, and nerve fibers, were found within the circular muscle layer and myenteric plexus of the small intestine and the latter was especially rich of this kind of nerves. Most of these positive neurons were Dogiel I type neurons and they often gathered in cluster in the ganglia. Each ganglion contained several to dozens of NOS positive neurons. Although no colocalization of ICCs and NOS positive nerves was found by double staining of whole mount preparations and cryo sections, they were closely distributed. Conclusion Our results indicate that NO released by myenteric plexus, an inhibitory neurotransmitter, may possess the function of regulating ICCs and smooth muscle in late stage of the fetus.
