Abstract?AlM:To investigate the effects of the MUC5AC levels and ocular function of the patients with glaucoma and cataract with combined surgery.? METHODS: Twenty - eight patients treated with glaucoma and cataract combined surgery were chosen as the observation group from December 2011 to June 2014 in our hospital, and other 28 cases of glaucoma and cataract did not undergo surgical treatment were selected as the control group, 30 healthy subjects were as healthy control group. the MUC5AC level and ocular surface score of the three subjects before surgery 1d, after 3 and 6mo were compared.?RESULTS: The NUC5AC of the two groups of patients was significantly lower than that of the healthy control group before surgery (P<0. 05), the ocular function score was significantly higher than the healthy control group ( P<0. 05). After 1mo, the MUC5AC of the observation group were significantly lower than that of before surgery ( P<0. 05), after 3mo MUC5AC content gradually increased to preoperative levels, after 6mo the MUC5AC were significantly higher than before surgery (P<0. 05). After 1mo, ocular function scores were significantly higher than the preoperative ( P< 0. 05 ), while after 3mo, ocular function scores decreased after 6mo of ocular surface function scores were significantly lower than the preoperative (P<0. 05). While the control group after 6mo, with the passage of time, the MUC5AC content gradually reduce, ocular function score increased gradually. ?CONCLUSlON:To treat the patients with glaucoma and cataract with combined surgery, the level of MUC5AC can temporary decrease. Ocular function score can temporary increase in, but after 3mo, it can be gradually improved.

Seven compounds were isolated from fermentation extract of cave-derived Metarhizium anisopliae NHC-M3-2 by silica gel, semi-preparative HPLC and other chromatographic methods. Their structures were elucidated by UV, IR, MS and NMR methods as 2,3-dehydroindigotide G (1), (-)-regiolone (2), naphtho-γ-pyrone (3), indigotide G (4), indigotide B (5) destruxin A (6) and destruxin B (7). Compound 1 is a new glycoside naphthopyranone compound. The anti-hepatitis B virus (HBV) activity of these compounds was evaluated. The EC₅₀ and CC₅₀ of compound 3 against HBV were 4.5 μmol·L^-1 and 92.3 μmol·L^-1, respectively. This is the first report of the antiviral activity of compound 3.

Objective To explore the reason and remedy on tumor patients' PICC misplacement.Methods The reason of 32 tumor patients' PICC misplacement were analyzed. The patients whose PICC misplaced were observed by X-ray,and then regulated to precava before remove the wire.Results PICC misplacement was much more observed in patients who was sixty years old or above than that of their younger counterpart (x2 =4.733,P ＜0.05).87.5％ of PICC misplacement were observed in the ipsilateral vein and less observed in right upper extremity ( x2 =7.552,P =0.006).The rate of PICC misplacement of cephalic vein,median cubital vein and basilic vein respectively were 15.7％,8.89％ and 8.12％.And there was no significant difference was detected in the gender,method and the location of cancer ( P ＞ 0.05 ).Finally,all the misplacement PICC were regulated to the right place.Conclusions Adept technology makes success,and more attention should pay to elderly patients.It is better to insert PICC in patient' s right upper extremity,especially basilic vein,and then median cubital vein.Utilize the X-ray to adjust patients position,and matching inspiration to adjust PICC' s location in order to avoid misplacement.

OBJECTIVETo classify the Chinese isolates of Coltiviruses.

METHODSThree sets of primers were selected among them two were specific to the 9th and 12th segments of subgroup B2, and one was for the 12th segment of subgroup B1-All the Chinese isolates of Coltivirus selected in the experiment were classified according to the lengths of different amplicons of the reverse transcriptase-polymerase Chain reaction (RT-PCR). The homogenicity of the nucleic acids of the isolates BJ95-75 and YN-6 was also compared with other Coltivirus strains belonging to subgroup B2.

RESULTSWith the primers 12-854-S/12-B2-R, which were specific to the 12th segment of Coltivirus subgroup B2-850 bp amplicons were obtained from Beijing isolate BJ95-75 and all the Yunnan isolates such as YN-6, -67-1, -68-1, -69, -70-1, -70-2, -90, -92-2, -93 of Coltivirus 492 bp DNA fragments were also amplified from all of them with the segment 9th specific primers 9-JKT-S/9-JKT-R. However no positive results were obtained from Northeast isolates NE97-12, NE97-31 and control viruses YN-99(Orbivirus),YN-151-1(JEV) with the same two sets of primers. With 12-B1-S/12-B1R primers specific to the 12th segment of subgroup B1, no amplicons of right length were obtained from any of the Chinese isolates of Coltivirus and the control viruses. When compared the nucleic acid sequences of BJ95-75 and YN-6 with other Coltivirus strains such as Bannavirus, JKT6423, JKT6969, JKT7043, the amplicons from segment 12th of these two strains had more than 89.4% homology with the other strains, especially to the earlier Chinese isolate Bannavirus, the homolog was more then 98.9%. Nearly 96.5% and 99.2% of the nucleic acids of the amplicons from segment 9th of the two strains were being homologous to Bannavirus and about 84.0% to JKT6423, which had been classified into type B2a. But the maximal homogenicity was about 53% when compared with the other two coltivirus strains. JKT6969 and JKT7043 which had been classified into type B2b.

CONCLUSIONGenotyping the recent Chinese isolates of coltivirus for the first time in our country. Most of the Chinese isolates belong to subgroup B2, more exactly type B2a. The Northeast isolates NE97-12 and NE97-31 were not correctly grouped with the available primers.

Objective To investigate the correlation of serum cystatin C and creatinine levels with cerebral infarction. Methods Eighty-four patients with cerebral infarction diagnosed by clinical manifestations, CT and (or) MRI and 76 healthy subjects were selected. Cystatin C level was tested by enzyme-linked immunosorbent assay (ELISA) and creatinine level was tested by the method of nitroxanthic acid. The correlation of cystatin C and creatinine levels with cerebral infarction was explored. Results The level of serum cystatin C in the cerebral infarction group (1.69±0.60 mg/L) was significantly lower as compared with that in the control group (2.00±0.67 mg/L) (t=-3.084, P=0.002); the level of serum creatinine in the cerebral infarction group (86.62±14.02 μmol/L) was significantly higher as compared with that in the control group (80.88±13.71 μmol/L) (t=2.611, P=0.010). Negative correlation between level of serum cystain C and cerebral infarction was noted (r=-0.238, P=0.002),while the level of serum creatinine was positively related to cerebral infarction (r=0.208, P=0.010).Conclusion A close correlation between cerebral infarction and both the levels of cystain C and creatinine exists, with cystatin C being a protective factor and creatinine being a risk factor for clinical cerebral infarction.

OBJECTIVETo study the effect of human alpha-mannosidase Man2c1 transgene on tumor growth and metastasis in mice.

METHODSHepatoma cell H22 or squamous epithelial carcinoma cell S180 was subcutaneously inoculated into the right armpit of mice (wild type mice and 28#, 35#, and 54# transgenic mice). Tumor size was measured every week. Mice were sacrificed on day 9 or 10 and then the tumors were exercised and weighted. Tumors and lungs were fixed in formaldehyde and sectioned. The sections were stained with hematoxylin/eosin and examined under microscope. The red blood cells in spleen were destroyed by Tris-NH4Cl. Natural killer (NK) cell activity was detected with Yac-1 cell as target.

RESULTSH22 and S180 tumors grew faster in all the three transgenic mice (28#, 35#, and 54#) than in wild type mice. The average size and weight of tumors between the transgenic mice and wild type mice were significantly different (P<0.05). Most tumors in the transgenic mice invaded the surrounding tissues. In contrast, nearly all the tumors in wild type mice were capsulized. Three of 10 28# transgenic mice, 5 of 10 35# transgenic mice, 3 of 10 54# transgenic mice, and 1 of 10 wild type mice showed lung metastasis of H22 tumor. Two of 6 28# transgenic mice, 3 of 6 35# transgenic mice, 1 of 6 54# transgenic mice, and 0 of 6 wild type mice showed lung metastasis of S180 tumor. No difference of NK activity in spleen cells was observed between the transgenic mice and wild type mice.

CONCLUSIONShMan2c1 transgene promotes growth, invasion, and metastasis of transplanted H22 and S180 tumors in mice. hMan2cl transgene does not affect NK activity in splenocytes.

OBJECTIVETo clarify the differential expression of the genes related to the lipid metabolism in the early stage of atherosclerosis in the young LDLR-/- mice of different ages.

METHODSA RT-PCR assay was used to analyse the gene expression patterns in the livers of LDLR-/- mice and wild type (WT) mice from 14 to 90 days. The characteristics of early lipid deposition in intima were evaluated using biochemical and pathological techniques.

RESULTSIn LDLR-/- mice, when compared to WT mice, the mRNA level of the apolipoprotein A IV (apoA IV), fatty acid translocase (Fat/CD36) and carnitine palmitoyl transferase I (CPT I) changed prominently at the age of 14-days (P < 0.05). At 30 days, the mRNA level of apolipoprotein A I (apoA I) was up regulated, but apolipoprotein F (apoF), CD36 and CPT I were down regulated (P < 0.05). At 60 days, the mRNA levels of apoA I, CPT I and liver X receptor alpha (LXRalpha) were up regulated, but apoA IV was down regulated (P < 0.05). At 90 days, the level of the apoA I was higher, but the expression of the apoA IV, apoF and acyl-coenzymeA oxidase 1 (ACOX1) were down regulated (P < 0.05), whereas the expression of apolipoprotein A V (apoA V), apolipoprotein E (apoE), peroxidase proliferator-activated receptor alpha (PPARalpha) and angiopoietin-like protein 3 (angptl 3) had no significant changes (P > 0.05). The serum levels of TC (P < 0.05), TG (P < 0.05) and LDLC (P < 0.05) in LDLR-/- mice were significantly higher than those in wild type mice with the same age.

CONCLUSIONSThe mRNA levels of the apoA I, apoA IV, apoF, FAT/CD36, CPT I, ACOX1 and LXRalpha of the LDLR-/- mice were significantly changed compared to the WT mice. The genes may be of some relevance to the complicated lipid metabolism network, and have effect in the early stage of atherogenesis.
