Objective To investigate the risk factors of renal inadequacy after postpartum hemorrhage. Methods According to the diagnostic criteria of postpartum hemorrhage, 200 cases of postpartum hemorrhage who were admitted to the Intensive Care Unit from January 2010 to December 2014 were collected. The general situation, history of pregnancy induced hypertension and gestational diabetes mellitus, ASA classification, anesthesia method, delivery mode, postpartum hemorrhage and other indicators. The risk factors were analyzed by logistic regression.Results Among 200 cases of postpartum hemorrhage who were admitted in the intensive care unit, 21 cases with renal insufficiency were seenafter delivery (10.5%) aged between 20 and 44 years old with the average age of (29.24 ±4.58) years old. Using the ASA evaluation criteria to evaluate the preoperative situation, we observed179 cases in ASA grade levelⅠ (89.5%), 20 casesin level Ⅱ (10%), one casein level Ⅲ (0.5%) and no case in grade Ⅳ. Among all the women, we found 147 cases of vaginal delivery (73.5%), 53 cases of cesarean section (26.5%),196 cases of spinal anesthesia (including labor analgesia) (98%) and 4 casesof general anesthesia (2%) . There were 12 patients with hypertension during pregnancy (6%), and 188 patients without hypertension (94%) . There were 9 cases of gestational diabetes mellitus (4.5%), and 191patients without gestational diabetes mellitus (95.5%).Conclusions The risk factors of renal insufficiency after postpartum hemorrhage were: age older than 35 years, cesarean delivery, pregnancy history of hypertension or gestational diabetes mellitus.

OBJECTIVETo investigate the anti-tumor effect of adenovirus-mediated Bcl-XL shRNA on colon cancer cells in vitro.

METHODSA recombinant Bcl-xl adenovirus was constructed, amplified, and purified. The effect on mRNA expression of Bcl-XL was assessed by RT-PCR, and the effect on apoptosis-induction of colon cancer(Lovo cell line) in vitro was assessed by MTT assay and cell clonogenic assay.

RESULTSRT-PCR showed that Ad/Bcl-XL shRNA significantly down-regulated the mRNA expression of Bcl-XL in Lovo cells. Ad/Bcl-XL shRNA suppressed the proliferation of Lovo cells in a dose-dependent as well as a time-dependent manner compared with Ad/GFP (P<0.05). Treatment with Ad/Bcl-XL shRNA dramatically suppressed the colony formation of Lovo cells in a dose-dependent manner (P<0.05). Ad/Bcl-XL shRNA showed no effect on normal human fibroblast.

CONCLUSIONAd/Bcl-XL shRNA exhibits cytotoxic effect on Lovo cells and may have the potential value in the treatment of colon cancer.

Objective To evaluate the efficacy and safety of memantine in the treatment of patients with Alzheimer' s disease (AD).Methods This was a 16-week,multi-center,randomized,double blind, placebo-controlled clinical trial (Study 10116).A total of 258 AD patients (MMSE score 5—18) were randomized in a 1:1 ratio into either memantine 10—20 mg/day (MEM,n=128) or placebo (PBO,n= 130) group for 16 weeks.Efficacy was primarily assessed in terms of changes of severe impairment battery (SIB) score in patients from baseline up to SIB assessment in the 16th week (16-week completers set, CS16).While ehanges of MMSE,ADCS-ADL_(19),and NPI (neuropsychiatric inventory) were evaluated as secondary efficacy parameters on both CSI6 and full-analysis set (FAS).Safety was assessed by physical examination,lab assays,ECG,and adverse events.Results 236 subjeets (CS16:MEM n=117,PBO n=119) were eligible for the efficacy assessment.No statistically significant difference between the treatments was observed on the primary and seeondary efficacy analysis,although both treatment groups had a slight increase from baseline in SIB total score.Post hoe evaluation of the data identified two bias factors that had a significant impact on the results of the pre-protoeol specified primary and secondary analyses.In a re-analysis of the data (CS16_(modified),MEM n=94,PBO n=95) excluding patient data affeeted by these factors,memantine-treated patients showed a statistically significant improvement related to placebo in the 16th week on the SIB (MEM 2.2 vs PBO 0.3,P=0.04),MMSE (MEM 1.0 vs PBO 0.1,P=0.03),and ADL (MEM 0.1 vs PBO-1.6,P=0.02) scales,indicating that memantine improved the cognitive function of AD patients and stabilized the activity of daily life.Memantine was well tolerated with an adverse event profile similar to that of placebo.Conclusion This study provides further support for pre-existing data,showing that memantine is efficacious,safe,and well-tolerated in patients with moderate to severe AD.

Background Prevention and treatment of posterior capsular opacification (PCO) is a hot issue.To establish a PCO animal model is the basis of relevant studies.The most common methods of creating a PCO model are phacoemulsification surgery with or without intraocular lens (IOL) implantation.But the suitability of different methods is unclear.Objective This experiment was to compare the outcome between the two methods of establishing a PCO model in rabbit eyes.Methods Twenty New Zealand white rabbits were collected and randomized into 2 groups.Phacoemulsification of cataract with IOL or without IOL implantation was performed on the right eyes of rabbits in these two groups.The operative eyes were examined under the slit lamp from day 1 through 3 months after surgery.The inflammatory response was evaluated and compared between the two groups,and the extent of PCO was graded based on Odrich's criteria.The use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The inflammatory response,including conjunctival congestion,corneal edema and aqueous flare were less severe in the model eyes with IOL implantation than the eyes without IOL implantation 1-3 days after operation.Inflammatory response gradually disappeared and showed the same degree in the PCO grade from 2 weeks through 3 months in both groups.The numbers of eyes with 1-3 grade of PCO were 8 and 9,and those with 0 grade of PCO were 2 and 1 in the with IOL implantation group and without IOL implantation group,respectively,showing a significant difference (P=0.39).PCO appeared at 1 month,extended at 2 months and formed dense fibrosis following operation.Conclusions The model outcome of phacoemulsification combined with IOL implantation is better than without IOL implantation one.It is the ideal animal model for the study of after cataract.

AIM:To observe the application efficiency of 5g/L indocyanine green ( ICG ) staining technique for continuous circular capsulorhexis ( CCC ) during phacoemulsification in white cataract.
METHODS:Ninety-eight patients (98 eyes) with white cataract were randomly divided into staining group ( 50 cases, 50 eyes) and control group (48 cases, 48 eyes). The control group didn't do anterior capsule staining. The staining group was injected to fill the anterior chamber, 5g/L ICG 0.1mL was applied on the central surface of the anterior capsule, using a 27G blunt needle through the side-port after 30s, and the redundant ICG was replaced by BSS, and continuous curvilinear capsulorhexis was accomplished using capsulorhexis forceps.
RESULTS: In staining group: after ICG staining, the capsule, which presented uniform light green and visualization of the anterior capsule was significantly improved. There are 48 eyes capsulorhexis success. The rate of success was 96%. Meanwhile, in control group, there was 29 eyes capsulorhexis success. The rate of success was 60%. The difference was statistically significant (P<0. 05). During follow-up, no dye particle and the complications of iritis or high intraocular pressure were found in the eyes of staining group. Anterior chamber inflammation, corneal opacity compared with control group, the difference was not statistically significant.
CONCLUSION:Indocyanine green staining increases the visibility of anterior capsule in over mature cataract, and it should be an effective and helpful method which can increase the success rate of capsulorehxis. At the same time, it can reduce the incidence of intraoperative complications. This will help beginners quickly grasp continuous curvilinear capsulorhexis, and shorten the learning curve.

?AlM: To compare the clinical effect between small-incision cataract surgery and phacoemulsification.
?METHODS: Totally 93 patients ( 124 eyes ) with age-related cataract who received treatment in Mar 2010 and Feb 2013 were dicided into 2 groups randomly. Forty-two patients ( 59 eyes ) in group small - incision cataract surgery ( SlCS ) were treated by SlCS, while other 51 patients ( 65 eyes ) in group Phaco were treated by phacoemulsification. And then, postoperative visual acuity, corneal astigmatism, surgically induced astigmatism ( SlA ) and intraoperative and postoperative complications were contrasted between groups.
?RESULTS: After 1d and 1wk of postoperation, there were 38 eyes ( 64. 4%) and 41 eyes ( 69. 5%) having a better visual acuity of 0. 5 in the SlCS group, while there were 29 eyes (44. 6%) and 32 eyes (49. 2%) in the Phaco group. The vision of SlCS group was better than that of Phcao group (χ2 = 4. 877, 5. 242, P < 0. 05 ). On postoperative 1 and 3mo, with acuity of 0. 5 or better, eye numbers showed no statistically significant differences between two groups (χ2 = 0. 005, 0. 085, P>0. 05). The average corneal astigmatism used analysis of repeatedly measuring designing variance: Comparing the corneal astigmatism in intra - groups at different times, it was statistically significant (F=25. 624, P<0. 05), and had a tendency to decrease with time. However, there was no statistical significance for corneal astigmatism between groups (F=0. 986, P>0. 05). The coneal astigmatism of each group was higher at 1wk after the surgery than that of preoperation, and the contrast had statistical sigenficence (t=2. 906, 2. 427, P<0. 05). The Phaco group with SlA was lower than the SlCS group at 1wk and 1mo after the surgery (t=-4. 628, 2. 770, P<005). lt had no statistical significance in SlA by comparing with the two groups at 3mo after the surgery (t=0. 754, P>0. 05). There were statistical differences in SlA at different time both by intra-group comparison and group comparison ( F=26. 37, P<0. 05, F = 14. 29, P<0. 05). The comparison of posterior capsule rupture, the postoperative corneal edema and anterior chamber pigment membrane reaction in two groups showed no statistical significance.
?CONCLUSlON: Our research shows that small-incision cataract surgery and phacoemulsification had similar effect in the treatment of cataract. Phacoemulsification is not the only surgery option for the best treatment effect. Small- incision cataract surgery can be popularized in basic- level hospitals, achieving the effect similar to phacoemulsification.

BACKGROUND/AIMS: Although lipoprotein lipase (LPL) gene Pvu II polymorphism has been associated with an increased risk of hypertriglyceridemia (HT), there is no clear consensus within the scientific community. METHODS: A meta-analysis of 1,640 subjects from six individual studies was conducted to better elucidate the potential relationship between the LPL gene Pvu II polymorphism and HT within the Chinese population. Pooled odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) were evaluated by using fixed effect models. RESULTS: Our analysis indicated a significant association between LPL gene Pvu II polymorphism and HT within the Chinese population under allelic (OR, 1.550; 95% CI, 1.320 to 1.830; p = 1.158 × 10-7), recessive (OR, 0.540; 95% CI, 0.390 to 0.750; p = 0.0002), dominant (OR, 1.889; 95% CI, 1.501 to 2.377; p = 5.960 × 10-8), homozygous (OR, 2.167; 95% CI, 1.531 to 3.067; p = 1.242 × 10-5), heterozygous (OR, 1.810; 95% CI, 1.419 to 2.309; p = 1.842 × 10-6), and additive genetic models (OR, 1.553; 95% CI, 1.320 to 1.828; p = 1.158 × 10-7). CONCLUSIONS: Because LPL gene Pvu II restriction fragment length polymorphism polymorphism was associated with an elevated risk of HT, the P+ allele carriers of the LPL gene might be predisposed to HT.
