Retinal vein occlusion ( RVO ) is a common vascular disease of the retina and is one of the main reasons for blindness. ln recent years, there have been some new understanding about the diagnosis and treatment of the disease, especially some new researches about treatment,for example ,in the therapy of the intravitreal injection of triamcinolone acetonide and anti-VEGFs as well as dexamethasone implant ( Ozurdex ) . This article will make a brief summarization of the progress about the diagnosis and treatment of RVO.

Objective To study the method and therapeutic results of intra-arterial interventional treatment (selective intra-arterial fibrinolysis) in acute cerebral infarction(ACl).Methods A total of 106 patients with ACI are divided into two groups:selective intra-arterial fibrinolytic therapy group(SIAF),intra-venously thrombolysis group(IVF);SIAF is selective entered into the obliterative artery with improved Seldinger's technich,pumped urokinase(UK) in a dose of 500 000 i.u.in NS.60ml within 40 minutes;arteriography is done all the time to know if the obliterative artery is unobstruct- ed,if it remains obstructe,then pumps 300 000 i.u.of UK,as long as it unobstructed,the treatment is finished at once; IVF is injected 1000 000 i.u.of UK in NS.150 mL by intravenous drip within 40 minutes,others like SIAF.Results The artery is disobliteration after thrombolysis,48 patients in SIAF,30 patients in IVF,P

Objective To identify the differential serum proteins in patients with hepatic injury resulting from coal-burning type of arsenism. Methods Six serum samples were collected from patients with liver injury resulting from coal-burning type of arsenism and healthy subjects(control gruop) in endemic arsenism area. Twodimensional gel electrophoresis(2-DE) was performed to separate serum proteins, after silver staining, the differential expression of proteins were analyzed and then identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF-MS). Results The 2-DE map of serum protein patterns of patients and normal control were established successfully. The results showed that there were an average of (824 ± 31 ) spots and (782 ± 42) spots on 2-DE matching of the patients and control groups and the matching rate was 94.9%(782/824). From these two groups 49 differential protein spots were identified, of which over 3 times the difference in the expression of 30 protein spots were singled out and MALDI-TOF-MS analysis was carried out. Ten proteins were identified. Upregulated expression was observed in alpha-2-macroglobulin, B-cell receptor-associated protein, keratin 1,apolipoprotein A-I, and down-regulated expression was observed in haptoglobin, α2-heremans-schimid-glycoprotein,mitogen-activated protein kinase 4, zinc finger protein 323, ZAP-70 and SP40 in the patient group. Conclusions The well-resolved and reproducible 2-DE serum patterns of patients are established and some differentially expressed proteins are characterized. Whether these proteins of differential expression are serum markers for liver injury resulting from coal-burning type of arsenism need to be further verified.

Objective: To study clinical application value of dobutamine stress echocardiography (DSE) and nitroglycerin stress single photon emission computed tomography (SPECT) for evaluation of restenosis after percutaneous coronary intervention (PCI). Methods: A total of 39 patients after PCI were examined by DSE and SPECT one week before coronary angiography (CAG). Dose incremental program of dobutamine included five levels：5μg•kg-1•min-1, 10μg• kg-1• min-1, 20μg•kg-1•min-1, 30μg•kg-1•min-1, 40μg•kg-1•min-1, and each level maintained for three minutes. Sensitivity, specificity and accuracy of DSE and SPECT were determined according to CAG examined result and examined results were compared between DSE and SPECT. Results: Compared with CAG, SPECT and DSE were no significant differences （P>0.05）in sensitivity (83.3% vs. 75.0%) and accuracy (71.8% vs. 87.2%) for evaluating restenosis after PCI, but compared with SPECT, DSE possessed higher specificity (66.7% vs. 92.6%). Conclusions: Dobutamine stress echocardiography is accurate, and its specificity is better than that of SPECT for evaluating restenosis after percutaneous coronary intervention.

Aim To explore the effect of prenatal expo-sure to lipopolysaccharide ( LPS ) on lipid metabolism in mice offspring from the starting point of FAT/CD36 expression.Methods 8-week old C57 mice mated 2∶1, then they were caged separately , marked as preg-nancy 0 d.The pregnant mice were given single intrap-eritoneal injection of 75 μg? kg -1 LPS, and the con-trol received injections of 0.2 mL saline .The perirenal adipose of female mice and epididymis adipose of male mice were collected in 4 w,8 w,12 w,respectively. The weight of visceral adipose tissue and the free fatty acid( FFA) and triglyceride ( TG) of adipose tissue and FAT/CD36 of offspring mice were quantitated .Results The body weight of offspring of LPS group was also significantly higher than that of NS group , and LPS group offspring displayed increased adipose tissue wet weights , the expression of TG and FFA was increased in LPS group compared with NS .Especially , prenatal exposure to inflammatory stimulation resulted in marked increase of FAT/CD36 and abnormal adipocyte development .Conclusions Inflammation induced by prenatal exposure to LPS results in increased body weight , adipose coefficient and FAT/CD36 that might develop into obesity in adult mice .These results are relevant in that anomalous local adipose tissue and FAT/CD36 regulation may be an important mechanism underlying obesity .

Abstract: Schistosomiasis is a serious major parasitic disease that threatens human life and health. A better understanding of the mechanism of host-schistosome interactions is the key to designing new prevention and control strategies. MicroRNAs (miRNAs) are endogenous small non-coding RNA molecules, which lead to the degradation of the target messenger RNA (mRNA) or inhibition of its translation in a sequence-specific manner. Both schistosome and its host produce miRNAs, which can be secreted by extracellular vesicles (EVs). There is accumulating evidence that miRNAs from schistosome can be taken up by host cells, and finely manipulate the phenotype of host cells for their survival or pathogenesis in a cross-species manner, even inhibiting the growth and metastases of hepatoma cells. It is still unknown whether host free miRNAs can be taken up by schistosome, but this phenomenon is highly probable. miRNA-mediated cross-species regulation has emerged as a novel mechanism for host-schistosome interactions, and this review summarizes the advances in this regard.

OBJECTIVETo observe the travel, divisions, and the lengths, diameters, branches, artery supplies of the main segments of maxillary nerve.

METHODSFifty formalin-preserved adult half-head specimens with intravascular injection of red color emulsion were used for the gross and microanatomical studies of maxillary nerve. The lengths, diameters, branches and artery supplies of four main segments of maxillary nerve were observed. SPSS 11.5 software was used to analyze the data.

RESULTSThe length and diameter of cranial middle fossa segment of maxillary nerve were (10.70 ± 1.31) mm and (4.01 ± 0.52) mm respectively, which was supplied by inferior-lateral cavernous sinus artery. The length and diameter of pterygopalatine fossa segment were (16.21 ± 1.80) mm and (3.27 ± 0.62) mm respectively, in which one zygomatic branch, one to three posterior superior alveolar nerves, two ganglion branches and tuberal descending branches; were given off, and the segment was supplied by foramen rotundum artery. The length and diameter of infraorbital segment were (25.73 ± 2.03) mm and (3.30 ± 0.52) mm and it gave off middle superior alveolar nerve (64%) and anterior superior alveolar nerve and was supplied by infraorbital artery. Facial segment gave off superior labial branches, internal and external nasal branches, inferior palpebral branches, buccal branch and zygomatic branch and these branches were supplied by infraorbital artery and superior labial and angular artery originating from facial artery.

CONCLUSIONSUnderstanding of travel and artery supply of maxillary nerve is helpful to regional anaesthesia and surgery for maxillary nerve. Foramen rotundum, sphenopalatine foramen and infraorbital nerve are important marks for endoscopic surgery in pterygopalatine fossa.

Congenital pulmonary hypoplasia is a rare developmental abnormality of the lung with an incidence rate of around 1/5000 000. As a fatal condition associated with respiratory insufficiency after birth, this disease is rare in adults. We treated a 29-year-old female patient with congenital pulmonary hypoplasia and concurrent of cystic duct calculus in May, 2011 using single-port transumbilical laparoscopic cholecystectomy, which resulted in a good therapeutic effect comparable to that by routine laparoscopic cholecystectomy.
