Objective To study the role of kallikrein 8 (KLK 8) in the pathogenesis of cerebral white matter injury induced by intrauterine infection.Method The pregnant Sprague Dawley rats were randomly assigned into two groups:the observation group and the control group.The rats in the observation group received intraperitoneal injection of lipopolysaccharide (500 μg/kg) by at day 18 and 19 of pregnancy,while the control group received the same dose of saline.The morphology of white matter of the newborn rats were observed at 1 d,3 d,7 d and 14 d after birth.The expression of KLK 8 in the hippocampus was examined using Western blot and reverse transcription-polymerase chain reaction (RTPCR);the concentration of KLK 8 in the serum was measured using enzyme linked immunosorbent assay (ELISA) method at the same time.Result In the observation group,the brain tissue was loose and edematous,the cerebral white matter was weakly stained,and the number of cells reduced.The expressions of KLK 8 in hippocampus in the observation group were higher than the control group [1 d:(0.24 ±0.01) vs.(0.23±0.01),3 d:(0.72±0.02) vs.(0.55±0.04),7 d:(1.08±0.04) vs.(0.84±0.04)],the differences were statistically significant (P ＜ 0.05).The expressions of KLK 8 mRNA in hippocampus of the observation group [1 d:(0.013 ±0.003),3 d:(0.032 ±0.002),7 d:(0.060 ±0.005)] were higher than the control group [1 d:(0.008 ±0.002),3 d:(0.016 ±0.002),7 d:(0.026 ±0.002)],the differences were also statistically significant (P ＜ 0.05).The serum KLK 8 concentration at 1 d,3 d,and 7 d were (5.13 ±0.24) μg/L,(6.46 ±0.24) μg/L,and (7.77 ±0.30) Iμg/L in the observation group,higher than the control group (4.73 ±0.25) μg/L,(5.65 ±0.29) μg/L,and (6.66 ±0.46) μg/L),the differences were also statistically significant (P ＜ 0.05).Conclusion KLK 8 may be involved in the pathogenesis of white matter injury induced by intrauterine infection.

AIM To evaluate the value of arsenic trioxide (ATO) in the treatment of systemic lupus erythematosus and to investigate its mechanism. METHODS① Thirty four BXSB lupus mice were averagely and randomly divided into ATO treated group and control group. The mice of ATO treated group were given (ip) ATO 0.4 mg·kg-1 every other day until d 105 and the observation was ended on d 210. The survival rate of mice was recorded, and the levels of serum IgG and anti-dsDNA antibody were measured with enzyme-linked immunosorbent assay. ② Other 20 BXSB lupus mice were also divided into 2 groups and treated as above and sacrificed on d 90. The spleen and kidneys of each mouse were removed and total RNA was extracted. The levels of interferon-γ (IFN-γ) mRNA in renal and spleen tissues were measured by using reverse transcription polymerase chain reaction. RESULTSUp to d 210, 8 mice died in ATO treated group and 13 died in control group. On d 90 and d 105, the average levels of serum anti-dsDNA antibody (A450 nm) were (0.335±0.011) and (0.223±0.017) in ATO treated group, and (0.688±0.016) and (0.683 ±0.014) in control group. On d 90, the expressions of IFN-γ mRNA in spleen and renal tissues of ATO treated group were significantly lower than that of control group. On d 105, the serum level of IgG was much lower in ATO treated group than that in control group, which were (4.9±1.3) and (6.9±1.0)g·L-1, respectively. CONCLUSION ATO elevates the survival rate, lowers the serum levels of IgG and anti-dsDNA antibody, and depresses the expression of IFN-γ mRNA in spleen and kidney tissues of BXSB mice.

Objective To systemically review the efficacy and safety of heparin for treatment of sepsis.Methods Database search of IM/MEDLINE,Cochrane Library,SCIE,CBM,CNKI,VIP Data,WanFang Data (from January 2000 to June 2012) was conducted.The quality of included randomized controlled trials (RCTs) about heparin for treatment of sepsis was assessed,and relevant data were extracted according to the inclusion and exclusion criteria.Then meta analysis was performed using RevMan 5.1.Results 17 trials with 1 167 participants were included.The results of meta-analysis showed:compared with the control group,heparin significantly decreased 28-day mortality in patients with sepsis [odds ratio (OR) =0.59,95％ confidence interval (95％CI) 0.45-0.77,P=0.0001] ; heparin did not deteriorate coagulation disorders,but corrected sepsis-induced platelet (PLT) count reduction [mean difference (MD) =13.94,95％ CI 10.15 to 17.72,P＜0.000 01],while it had no significant effect on the activated partial thromboplastin time (APTT) and prothrombin time (PT,APTT:MD=-3.18,95％CI-6.88 to 0.53,P=0.09; PT:MD=-0.68,95％ CI-1.48 to 0.12,P=0.09).There was no significant difference between the two groups in the incidence of bleeding either.Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score of heparin group was significantly lower than that of the control group (MD=-2.58,95％CI-3.29 to-1.87,P＜0.000 01),and the incidence of multiple organ dysfunction syndrome (MODS) was significantly lower than that of the control group (OR=0.32,95％CI 0.17 to 0.61,P=0.000 6).In addition,heparin could shorten intensive care unit (ICU) stay (MD=-4.43,95％CI-6.79 to-2.07,P=0.000 2),whereas it showed no significant effect on the total length of hospital stay.Conclusions Heparin can ameliorate sepsis,and has high degree of safety and lower hospital expense.Due to limitation of the quality of included studies,larger sample and well-designed RCTs are needed to further support this conclusion.

Objective To explore a suitable mode of prenatal ultrasound diagnosis of fetal malformations with early neonatal surgical treatment. Methods Nine fetus with surgical malformations diagnosed prenatally by ultrasound in our hospital from Mar. 1998 to Dec. 2000 were analysed. Results There were two cases diagnosed in the second trimester, 7 in the third trimester, including 1 duodeneal atresia with annular pancreas, 1 abdominal wall defect, 1 congenital diaphragmatic hernia, 1 huge omphalocele, 1 high imperforate anus, 4 hydronephrosis (2 mild and 2 severe). Six cases were operated in neonatal period, two were treated conservatively, and one did induced abortion. All cases recovered except 1 death. Conclusions The mode of prenatal ultrasound diagnosis with surgery in early neonatal period is a suitable way in China before the fetal surgery is applied. It is important to make effort to increase sensitivity of sonographic diagnosis of fetal malformation and to get early treatment in perinatal period.

Objectives To evaluate bioMerieux VIDAS(Vitek Immune Diagnositc Assay System) Chlamydia test (CHL) and to determine its performance(sensitivity and specificity) by comparing with cell culture. Methods C. trachomatis in urogenital samples was detected by both cell culture and VIDAS CHL. The different results were confirmed by direct fluorescent antibody assay (DFA). The sensitivity to C.trachomatis serotype D and E stocks was alsode tected with VIDAS CHL and cell culture. Results C.trachomatis was found in 33 (20.2%) of 163 urogenital samples by cell culture in coutrast to in 44(27.0%) by VIDA CHL. As the expanded gold standard was defined as either cell culture positive or cell culture negative and both CHL and DFA positive, the sensitivity was 80.5% and 95.3% and the specifiaty were 100% and 97.6% in cell culture and VIDAS CHL, respectively. In the sensitivity test, C. trachomatis serotype D was tested positive at the highest dilution of one to 102 400 dilution and serotype E was at one in 51 200 by cell culture. However, both serotype D and E were tested positive at the highest dilution of one to 6 553 600 by VIDAS CHL. Conclusions Comparing with the expanded gold standard, VIDAS CHL is sensitive and specific for C.trachomatis in urogenital specimens, with simple and short running hours (1 h). First catch urine (FCU), which avoids the painful male swab collectionin male patients, could also be used as specimen in VIDAS CHL test.

AIM: To explore the possible anti apoptotic mechanism of ginsenoside Rg1 on MPP + induced cellular apoptosis. METHODS: The apoptosis of SHSY5Y induced by MPP + was observed by AO EB staining. Flow cytometry was used to quantitate mitochondrial transmembrane potential (△?m) and reactive oxygen species (ROS) . Western Blot was used to detect the expression of bcl 2 and bax proteins in SHSY5Y cells. RESULTS: MPP + induced apoptosis in SHSY5Y cells was obviously inhibited by pretreatment with 10 ?mol?L -1 Rg1. Although there was no difference of mitochondrial transmembrane potential between Rg1 pretreated groups and MPP + groups, the level of ROS in Rg1 pretreated groups decreased, the expression of bcl 2 protein increased and expression of bax protein decreased. CONCLUSION: Rg1 protects against MPP + induced apoptosis in SHSY5Y cells and the effect may be attributed to its remove of ROS and its regulation of expression of bcl 2 and bax proteins.
