Purpose:To study the connection between the blocking of N-acetylglucosaminyltransferase V(GnT-V) and endoplasmic reticulum stress(ER stress). Methods:The recombinant plasmid expressing siRNA of GnT-V was constructed and transfected into SMMC-7721. The key molecules such as GRP78,XBP1 and PERK during ER stress was analyzed in mRNA and protein levels. Results:GRP78 mRNA and protein levels were upregulated, the spliced forms of XBP1 mRNA and protein appeared and ER eIF2? kinase PERK was activated. Conclusions:These results suggest the blocking of GnT-V in SMMC-7721 induces cellular ER stress.

Objective To investigate the effects of treatment of syphilis in pregnancy on perinatal prognosis. Methods Patients of syphilis in pregnancy from Hainan Provincial People′s Hospital and Haikou Municipal Maternal and Child Health Center during 1995.1 to 2001.1 were collected for retrospective analysis. Pregnant women with syphilis were divided into treated group and untreated group according to whether they received penicillin anti syphilis treatment or not during pregnancy. Results The total number of deliveries in the 2 hospitals during that period was 18 701, and 61 out of 9 805 women screened for syphilis were positive, giving an incidence of 6 2/1000. The perinatal mortality rates were 11 2% in treated group and 83 3% in untreated group, and incidences of congenital syphilis were 17 6% and 72 7% respectively. Conclusion Syphilis in pregnancy is a serious complication to harm the fetus. Screening of syphilis during pregnancy is necessary, and penicillin treatment is effective which may reduce the perinatal mortality rate and the birth of congenital syphilis baby.

Objective To explore the effect of a herbalcompound Gehua Jiejue Dizhi Decoction (GJDD) on the liver fat deposition and the expression of PXR, and the mRNA and protein expression of its target genes CYP3A11 and CYP3A25in the liver tissues of mouse models of alcoholic fatty liver.Methods Twenty-nine healthy male C57BL/6J mice were randomly divided into control group (n=5), model group (n=8), high dose GJDD group (n=8)and low dose GJDD group (n=8).The mouse model of alcoholic fatty liver was prepared according to the National Institute on Alcohol Abuse and Alcoholism (NIAAA) method.Then, the mice were treated with the high dose and low dose GJDD for 9 days.Serum glutamic-pyruvic transaminase (AST) and aspartate aminotransferase (AST) were detected by enzyme-linked immunosorbent assay (ELISA).Liver fat deposition was detected by oil red O staining.Real-time RT-PCR and immunohistochemistry were performed to examine the expressions of PXR, CYP3A11 and CYP3A25.Results Compared with the model group, the liver fat deposition in the intervention groups was significantly reduced in a dose-dependent manner, with a significant increase of the expression of PXR and CYP3A25 (P < 0.01).The serum ALT level was significantly reduced in the model group (P < 0.01), while the transcriptional levels of CYP3A11 mRNA in the groups were similar (P ≥ 0.05).Conclusions Gehua Jiejue Dizhi Decoction has obvious therapeutic effect on the AFLD in mice, which may be related to the activation of PXR and its target genes CYP3A25.

One hundred and twenty stroke patients were randomly divided into rehabilitation group (n =60) and control group (n =60).Patients were assessed with National Institute of Health Stroke Scale (NIHSS) ,Fugl-Meyer Assessment (FMA),Bathel Index (BI) and World Health Organization Quality of Life Assessment Instrument Brief Version(WHOQOL-BREF) before and 6 weeks after treatment by the same doctor.The scores of NIHSS,FMA,BI and WHOQOL-BREF were improved significantly in rehabilitation group after treatment; while those of control group were no improved.The scores after treatment of rehabilitation group were significantly higher than those of control group ( P ＜ 0.05 ).

Five hundred elderly patients with ischemic stroke admitted from January 2008 to December 2010 were enrolled in the study,including 352 recurrent cases and 148 primary cases.There was a positive correlation of stroke recurrence with age,blood pressure,blood glucose and lipid levels,smoking and alcohol consumption of patients(P ＜0.05 ); while the stroke recurrence was negatively correlated with physical exercise(P ＜ 0.05).Stepwise multiple regression analysis indicated that the blood pressure,blood glucose and lipid levels were risk factors for the recurrence of ischemic stroke in elderly patients.

Objective:To compare the surgical outcomes between arthroscopic coracoclavicular ligament reconstruction and open modified Weaver-Dunn procedure for the treatment of acromioclavicular joint dis-locations.Methods:From January 2011 to June 2012, 63 consecutive patients with acromioclavicular joint dislocations who were treated with either arthroscopic coracoclavicular ligament reconstruction or open modified Weaver-Dunn procedure were retrospectively reviewed after the final follow-up.There were 49 men and 14 women with a mean age of (40.3 ±10.6) years.The mean time from injury to surgery was (10.3 ±5.3) d.According to the Rockwood classification, there were 45 patients with type V injury and 18 patients with typeⅢinjury.All the patients with typeⅢinjury claimed high level of sport activi-ty.The patients were divided into the arthroscopic surgery group (32 cases) or the open surgery group (31 cases) depending on the type of the surgery that each patient had taken.All the patients were rou-tinely followed up after the surgery.The visual analogue score ( VAS ) , American shoulder and elbow surgeons( ASES) score and University of California Los Angeles( UCLA) score were employed to evaluate the postoperative shoulder function.The postoperative radiographs of both shoulders were taken for each patient to evaluate the loss of reduction of the acromioclavicular joint.Re sults:The mean follow-up time was (29.6 ±6.0) months ( range:24 to 43 months) .No significant difference was found between the
arthroscopic surgery group and the open surgery group with regard to the patient’ s age [(41.0 ±10.5) years vs.(38.0 ±10.8) years], gender (male/female,24/8 vs.25/6), classification (Ⅴ/Ⅲ,22/10 vs. 23/8), time from injury to surgery [(10.6 ±4.9) d vs.(10.1 ±5.7) d], dominant involvement (19/32 vs.17/31)and mean follow-up time [(29.8 ±6.4) months vs.(29.5 ±5.5) months], P>0.05.At the end of the last follow-up, no significant difference was noted between the two groups regarding the mean forward elevation [(164.4 ±17.2) degrees vs.(162.6 ±12.9) degrees], mean external rotation [(60.9 ±17.0) degrees vs.(57.3 ±15.8) degrees], mean internal rotation [(T12 ±3 vertebrae) vs. (T12 ±3 vertebrae)], mean ASES scores (96.0 ±5.1 vs.94.5 ±3.8)and UCLA scores (34.2 ±1.5 vs. 33.7 ±1.4), P>0.05.The rate of loss of reduction was significantly lower in the arthroscopic surgery group (1/32) compared with the open surgery group (7/31, P=0.026).Conclusion:Surgical treatment for acromioclavicular joint dislocations with either arthroscopic reconstruction or open modified Weaver-Dunn procedure could yield good results with no significant difference between the two groups as for the postoperative shoulder function.The rate of loss of reduction was lower in the arthroscopic surgery group compared with that of the open surgery group.

Objective:To evaluate the antimicrobial effectiveness of Zhenzhu Mingmu eye drops according to the requirements de-scribed in Chinese pharmacopoeia (2010 edition). Methods:Totally 7 batches of Zhenzhu Mingmu eye drops from 7 enterprises were evaluated. All the samples were tested according to the requirements described in Chinese pharmacopoeia, and the testing points of 6h and 24h were added. Results:As for bacteria, the reduction value of staphylococcus aureus in 7 days treated with Zhenzhu Mingmu eye drops from enterprise e was 0. 61g, and that in 14 days was 1. 01g. That in 7 days treated with the eye drops from the other enter-prises was all above 1. 01g, that in 14 days was above 3. 01g, and that in 14-28 days kept stable. As for fungi, the number was stable from the beginning with the treatment of the eye drops from the seven enterprises. Conclusion:Although the type and content of bacte-riostatic agent in domastic Zhenzhu Mingmu eye drops are the same, there is difference in the antimicrobial effectiveness of the product from different enterprise. The eye drops from one enterprise can't meet the requirements for type I product described in Chinese pharma-copoeia,and the others meet the requirements.
