OBJECTIVETo observe the efficacy of Xingnaojing Injection (XI) in treatment of sepsis-associated encephalopathy (SAE).

METHODSTotally 65 SAE patients were retrospectively analyzed at EICU from September 2010 to September 2013. They were assigned to the control group (32 cases) and the treatment group (33 cases) according to whether they received XI. Patients in the control group received anti-infection and symptomatic support, while those in the treatment group were intravenously injected with XI at 20 mL per day for additional 7-10 days. The fever clearance time, Glasgow coma scale (GCS), C-reactive protein (CRP), neuron-specific enolase (NSE), and improvement of electroen-cephalogram (EEG) were observed in the two groups.

RESULTSCompared with the control group, the fever clearance time was shortened, CRP levels decreased, GCS score and efficacy of EEG was alleviated in the treatment group after treatment with statistical difference (P < 0.05). No adverse reaction occurred during medication.

CONCLUSIONX1 was safe and effective in treatment of SAE.

Objective To investigate the changes in tumor necrosis factor-α(TNF-α) and plasminogen activator inhibitor(PAI) in the presence of obstructive sleep apnea syndrome(OSAS) in patients with type 2 diabetes mellitus,and to investigate if that 2 inflammatory factors is associated with hypoxemia during sleep.Methods Fiftyfour patients with type 2 diabetes mellitus hospitalized for glycemic control were subgrouped into 27 patients with OSAS (group O) and 27 patients without OSAS (group N).26 people without diabetes and OSAS were selected from a health check-up program to serve as control group (group C).Serum TNF-α and PAI levels were measured by commercial ELISA kits.Apnea hypopnea index (AHI),the lowest pulse oxygen saturation (LSpO2) at night were detected by portable sleep monitor.The relativity regarding TNF-α,PAI,homeostasis model assessment for insulin resistance (HOMA-IR),fasting blood glucose(FBG),AHI,LSpO2,and age was discussed.TNF-α and PAI were regard as dependent variables,and FBG,HOMA-IR,AHI,LSpO2,and age as independent variables in multivariate stepwise linear analysis.Results The levels of HOMA-IR,TNF-α,PAI in group O [2.69 ± 1.53,(1.97 ±0.13) ng/ml,and (2.27 ± 0.85) ng/ml] were higher than the those in other 2 groups,and those in group N [1.70 ± 0.88,(1.09 ±0.29) ng/ml,and (1.59 ± 0.13) ng/ml] were higher than group C [1.15 ± 0.67,(0.73 ± 0.19) ng/ml,and (0.89 ±0.25) ng/ml].The levels of FBG in the 2 diabetic groups were higher than those in group C.The level of AHI in group O was higher than that in group N and group C,while LSpO2 in group O was lower than that in group N and group C.Spearman univariate analysis showed that TNF-α and PAl both were associated positively with HOMA-IR,FBG,and AHI,while negatively with LSpO2.Multivariate stepwise linear analysis denoted that TNF-α was independently associated with AHI,FBG,while PAI was independently associated with AHI and HOMA-IR.Conclusions Patients with diabetes and OSAS manifest raised level of chronic inflammatory activity,and therefore,OSAS might be implicated in the pathogenesis of chronic complication of patients with type 2 diabetes.

AlM: To evaluate the effectiveness and security of lift and squeeze technique in phacoemulsification of hypermature cataract.
METHODS: From June 2010 to June 2013, totally 156 eyes with hypermature cataract, which received phacoemulsification in our hospital, were enrolled. Lift and squeeze technique was used to chop the nucleus, and 1g/L Trypan blue was used for capsulorhexis. Average time of phaco complication, corneal edema and visual outcome were recorded.
RESULTS: The best-corrected visual acuity ( BCVA ) was 0. 1-0. 4 in 15 eyes (9. 6%), 0. 5-0. 7 in 82 (52. 6%) eyes, and 0. 8-1. 0 in 59 ( 37. 8%) eyes at 3mo after surgery. The phaco time was 25-56s (average 42±10s), the maximum phaco power was 30%. Posterior capsular rupture and vitreous loss happened in 2 eyes (1. 3%), and the lOLs were implanted in the sulcus. Corneal edema classified at grade Ⅰ were seen in 12 eyes (7. 7%), and 5 eyes (3. 2%) at gradeⅡ, no eye at gradeⅢ and gradeⅣ. The mean endothelial cell loss was 8. 7%at 3mo.
CONCLUSlON: Crystalline lens capsule staining with Trypan blue increase the success rate of intact continuous curvilinear capsulorhexis ( CCC ) . The lift and squeeze technique reduces the stress on the zonules and capsule, and decreases the phaco time and phaco power.

In order to establish the optimum condition for purifica tion of the nucleoprotein(NP) of rabies virus by immunoaffinity chromatography, the efficient and non-denaturative eluents(Mg-el) was obtained by using ELISA elution model; furthermore, it didn't damage the activity of NP. Two kind of NPs , expressed by recombinant vaccinia virus (rVac-N) and recombinant baculovirus (BRN), were purified by a Sepharose CL 4B column and a 2C12- Sepharose 4B colum n. By Western-blot and SDS-PAGE, high purity and good antigenical intact NPs w ere identified. The purified ribonucleoprotein (RNP) of rabies virus 5aG strain was also obtained. After immunized with NP and RNP, mice developed a strong anti -nucleoprotein response and were protected against a lethal challenge of rabies virus CVS strain. There were not difference been observed among the mice immuni zed with different purified protein. These data indicate that the NPs are antige nical and immunogenical comparable to the authentic rabies RNP and therefore pre sent a potential source of an effective ,safe and economical subunit vaccine.

Objective To investigate the effect of a novel lymphotoxin with selectively binding to p55 tumor necrosis factor receptor (p55TNFR) on myocardial ischemia-reperfusion injury in rats in order to explore the mechanism.Methods A total of 40 SD rats were randomly (random number) assigned into four groups (n =10 in each),namely sham operation group (group A),I/R group (group B),wild type rhLTα treatment group (group C),and p55TNFR selective rhLTα (rhLTα-Q107E) treatment group (group D).After I/R model rats were established,various therapeutic agents or saline were given by continuous intravenous infusion for 24 h via a micropump.After 24 hours of treatment,serum myocardial zymogram,such as aspartate aminotransferase (AST),lactate dehydrogenase (LDH) and creatine kinase (CK),as well as superoxide dismutase (SOD),malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) activities were determined.Myocardial infarction size (MIS) was measured by nitro blue tetrazolium chloride (NBT) staining.Results Compared to sham operation group,MIS,AST,LDH,CK,MDA were increased,while the activities of SOD and GSH-Px were decreased.However,all the effects were significantly reversed by treatment with rhLTα-Q107E (P ＜ 0.05) but not rhLTα (P ＞ 0.05).Conclusions The rhLTα-Q107E plays a role in the protection against myocardial ischemia-reperfusion injury in rats by the mechanism of scavenging oxygen free radicals and increasing the activity of endogenous antioxidant system.

Aim To explore the changes of Apelin/APJ system in LPS-induced injury of rat pulmonary mi-crovascular endothelial cells( PMVECs) , and the effect and mechanism of Apelin. Methods PMVECs were cultured with the explant technique, and the identifica-tion of rat PMVECs was carried out by immunocyto-chemical staining of factorⅧrelated antigen. MTT as-say was used to evaluate the viability of PMVECs. The mRNA expression of Apelin and APJ was detected by RT-PCR. The protein expression of PCNA and the phosphorylation of Akt was analyzed by Western blot. Results The mRNA expression of Apelin and APJ showed a compensatory increase after LPS treatment for a short period of time ( P<0. 01 ) , but with the exten-sion of time, which was significantly inhibited, even lower than the control group ( P<0. 05 or P<0. 01 ) , suggesting that Apelin/ APJ system might be involved in LPS-induced PMVECs injury. MTT results showed that 10 -6 ~10 -9 mol · L-1 Apelin obviously promoted the proliferation of rat PMVECs ( P <0. 05 or P <0. 01 ) , and with certain concentration and time de-pendence. Moreover, Apelin also improved the LPS-induced PMVECs injury in different degrees ( P<0. 05 or P < 0. 01 ) . In addition, Western blot analysis showed that Apelin significantly reversed the decrease of the protein expression of PCNA and the Akt phos-phorylation level induced by LPS ( P <0. 05 or P <0. 01 ) . Conclusions The Apelin/APJ system is in-volved in LPS-induced PMVECs injury. Apelin plays an important role in protecting the pulmonary microvas-cular endothelial function and reversing the LPS-in-duced PMVECs injury, which might be related to the activation of Akt phosphorylation pathway.
