AIM: To evaluate the efficacy of combined therapy for amblyopia in children by making use of pattern visual evoked potential ( P-VEP) game.
METHODS: This was a prospective case control study. These asthenopic children were divided into two groups. The control group ( 66 eyes of 49 patients ): occlusive therapy with glasses, cover, precision work, red light treatment and so on, later the stereo vision training was added. The experimental group (72 eyes of 52 patients):conventional methods mentioned above with P - VEP games.
RESULTS: The total effective rate and cure rate of experimental group in 6mo were higher than those of control group. The overall effective rate was 94. 4% in the experimental group and 83. 3% in the control group. There was a statistically significant difference between them (P<0. 05).
CONCLUSION: The comprehensive therapy by making use of P-VEP game is an individualized effective new way in treating amblyopia.

Objective Preliminary study of the cough reflex sensitivity test in chronic cough patients with different gender,disease duration and causes to evaluate the clinical diagnostic significance of the test and further provide some information for the treatment of chronic cough.Methods Totally 108 chronic cough patients in our hospital were enrolled in the study with the final diagnosis of upper airway cough syndrome(UACS),cough variant asthma(CVA)and gastroesophageal reflux cough(GERC).They all went through the cough reflex sensitivity test and the retrospective analysis of the results was made.Results In 108 patients with chronic cough(76 UACS,19 CVA and 13 GERC),lgC5 was significantly slower in the female(1.80)than the male(2.40,P<0.05)and in the patients with cough duration over 12 months(1.80)than those with cough duration under 12 months(2.40,P<0.05).Cough sensitivity in patients with different causes was significantly different(P<0.05)with lower lgC5 in GERC patients(1.49)than CVA (2.40,P<0.05)and UACS(2.40,P<0.05)patients.Conclusion Cough sensitivity is different in chronic cough patients with different gender,disease duration and causes.Cough reflex sensitivity test is of great value in the etiology diagnosis of chronic cough.

ObjectiveTo explore the causes for descending of the serum testosterone (T) in middle-aged and elderly men with metabolic syndrome (MS).MethodsFifty-six male patients aged between 45 and 83 years old were investigated.Blood pressure,height and weight were measured,and body mass index (BMI) was calculated.Biochemical indice in fasting state [ fasting blood sugar (FBG),total cholesterol (TC),triglycerides (TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol (HDL-C) ],fasting insulin (FIN),and the level of serum testosterone) were detected.An insulin resistance index (IR) was calculated using homeostasis model assessment (HOMA).Participants were divided into the MS group and the non-MS group according to CDS diagnostic standard.The relationships between the level of serum Testosterone and each index were analyzed.ResultsThe level of serum Testosterone was significantly lower in the MS group than that in the non-MS group [ (9.97 ± 3.87 ) nmol/L vs.( 13.73 ± 3.93 ) nmol/L,t =3.337,P ＜ 0.01 ].Multiple regression analysis showed that the level of serum testooterone was negatively correlated with age,waist circumference and HOMA-IR ( regression coefficients:- 0.214,- 0.329,- 0.317; standardized regression coefficients:- 0.730,- 0.597,- 0.313 ; t =- 5.833,- 4.681,- 2.686 respctively; P ＜ 0.01 ).ConclusionThe level of serum testosterone descends in middle-aged and elderly men with MS.The level of serum testosterone is closely related to age,waist circumference and insulin resistance

Objective:To compare two flexible embryo catheters and determine whether clinical out-come differs in the in vitro fertilization-embryo transfer (IVF-ET)cycles.Methods:This prospective control study was conducted by one doctor between July 2012 and November 2013.In the study,2 064 patients undergoing fresh embryo transfer by using IVF-ET/intracytoplasmic sperm injection (ICSI)-ET in Reproductive Medical Center of Peking University Third Hospital were recruited.The subjects were di-vided into two groups.Cook Sydney IVF embryo transfer catheters (product model:K-JETS-7019-SIVF) were used for embryo transfer in group 1 (n =949),and FrydmanCCD catheters (product model:131230301)were used in group 2 (n =1 115).Pregnancy outcomes were compared between these two groups.Results:There was no significant difference in age,diagnosis for infertility and stimulation proto-col used between the two groups.In addition,there was no difference in the number of oocytes collected and in the number and score of embryos transferred.The significantly higher implantation rate,clinical pregnancy rate,and live birth rate (34.40% vs.26.92%,51.21% vs.41.52%,42.57% vs. 33.09%,P <0.05)were observed in group 1 compared with group 2.The abortion rate was not signifi-cantly different between the two groups (11.93% vs.15.98%,P >0.05).The proportion of difficult transfer was higher in group 1 than that in group 2 (5.27% vs.3.41%,P <0.05 ).There was no difference in the clinical pregnancy rate and live birth rate between the two difficult transfer cycles.Con-clusion:The type of embryo transfer catheter affects the clinical outcome in IVF.Good clinical outcome can be obtained by using Cook Sydney IVF catheter,which is worthy of clinical promotion.

Objective To explore the hurt of susceptibility organs and critical orgens followed by rotavirus (RV) infection of whole body in newborn mouse.Methods RV strain was derived from the stool samples of patients with RV diarrhea and was proved to be long type by methods of ELISA and polyacrylamide gel electrophoresis (PAGE). RV was inoculated by the pathways of taking orally and injected to abdominal cavities,respectively. The pathological changes of the newborn mouse model infected with human natural RV by light microscope and electron microscope. The gene probe was marked by digoxin.The direct prove of RV infection in these organs was got by the detection of in situ PCR. Results Pathological changes were found in the small intestinal villus,lamina propria of the stomach and the heart cells of the mice taken RV orally.The mice with intraabdominal RV injection showed pathological changes of the cells in the small intestinal villus,liver and kidneys observed by electron microscope.Shortened small intestinal villus,nuclear membrane disorganization,massive vacuolization,mitochondrial swelling and rough endoplasmic reticulum dilation were observed in the cells of small intestinal.In the liver of the mice,marked mitochondrial swelling and agglutination,cell nucleus pyknosis or collapse,presence of numerous lipid droplets and vacuoles were found in the li-ver cells,with lymphocyte and plasmacyte infiltration.Obvious dilatation and shedding of the microvillus were found in cholangioles.The mitochondria of the proximal convoluted renal tubule showed mild swelling,but the cells in the heart and lung did not display obvious changes.Conclusion RV can damage lots of extra intestinal organs of the newborn mice if RV diffuses to the whole body of the mice.

Objective To investigate the feasibility,security,indication and prophylactic measures of postpartum hemorrhage during the fetalintrapartum operation by analyze the maternal prognosis after intrapartum fetal operation(IFO) performed.Methods We performed a retrospective evaluation of 10 cases that has been performed intrapartum fetal operation(IFO group,n=10) successfully between August 2008 and October 2009 at Department of Obstetrics and Gynecology,Shengjing Hospital,China Medical University.Healthy pregnant women(n=10) were chosen as control group,who received Caesarean section for refusing to vaginal delivery.Between the two groups,we compared the indexes including blood lose during the operation and 24 hours post-operation,the hemoglobin level pre-operation and 24 hours post-operation,the involution of uterus,the puerperal infection,and the follow-up at 42 days post-operation.Results Good involution,no primary and secondary postpartum hemorrhage and no puerperal infection were found in both of the 2 groups.Intra-operation,24 hours post-operation and the total volumes of blood lose,the hemoglobin level before operation,24 hours post-operation and 42 days post-operation had no statistic significant difference between the IFO group and control group(P>0.05).No significant difference was found in the operation time between IFO group and the control group(66.40±53.40 minutes and 34.50±4.97 minutes,respectively.Intra-operation,24 hours post-operation and the total volume of blood lose had no relation to the maternal age and gestational weeks(P>0.05).The blood lose of intra-operation in IFO group had positive linear correlation to the operation time.(Pearson relation coefficient R=0.458,.P=0.021).The linear recurrence equation was:the volumes of blood lose intra-operation(ml)=172.68+1.342x(operation time).Conclusion IFO was safe to the mother.It did not affect the involution of uterus and could not increase the blood lose of postpartum and the puerperal infection morbidity.Through the effective measures of preventing postpartum hemorrhage,the postpartum blood lose of the patients that performed intrapartum fetal operation could be no more than that of the patients that had normal Caesarean section.Improving the technique of the intrapartum fetus operation and shortening the operation time are important to prevent postpartum hemorrhage.

OBJECTIVETo study the expression of stromal cell derived factor-1(SDF-1) and CXC chemokine receptor 4 (CXCR4) in the airway and the effect of budesonide on their expression in mice with asthma.

METHODSThirty BALB/c male mices were randomly divided into three groups: placebo control, untreated asthma, and budesonide-treated asthma. The asthma group were induced by intraperitoneal injection of 10% ovalbumin (OVA ) on days 1, 8 and 15, and then from days 22 to 34, challenged by inhalation of 2% OVA aerosol every other day. The budesonide-treated asthma group received an inhalation of budesonide (1 mg ) before OVA challenge. The pathological changes of the airway were assessed by hematoxylin and eosin staining. The immunohistochemistry was used to estimate the expression of SDF-1 in the lung. RT-PCR was used to evaluate the expression of CXCR4 in the lung.

RESULTSCompared with the control group, SDF-1 and CXCR4 expression in the lung in the untreated asthma group increased significantly (p<0.05). The budesonide-treated asthma group demonstrated significantly decreased SDF-1 (0.426+/-0.052 vs 0.361+/-0.065; p<0.05) and CXCR4 (0.829+/-0.027 vs 0.723+/-0.094; p<0.05) expression in the lung as compared with the untreated asthma group. Both SDF-1 (r=0.744, p<0.01) and CXCR4 (r=0.553, p<0.01)were positively correlated with the thickness of the airway wall.

CONCLUSIONSSDF-1 and CXCR4 may be associated with airway remodeling in mice with asthma. Budesonide can improve airway remodeling, possibly by decreasing the expression of SDF-1 and CXCR4.

Poly (ADP-ribose) polymerase-1 (PARP-1) plays as a double edged sword in cerebral ischemia-reperfusion, hinging on its effect on the intracellular energy storage and injury severity, and the prognosis has relationship with intervention timing. During ischemia injury, apoptosis and oncosis are the two main cell death pathway sin the ischemic core. The participation of astrocytes in ischemia-reperfusion induced cell death has triggered more and more attention. Here, we examined the protective effects and intervention timing of the PARP-1 inhibitor PJ34, by using a mixed oxygen-glucose deprivation/reperfusion (OGDR) model of primary rat astrocytes in vitro, which could mimic the ischemia-reperfusion damage in the "ischemic core". Meanwhile, cell death pathways of various PJ34 treated astrocytes were also investigated. Our results showed that PJ34 incubation (10 μmol/L) did not affect release of lactate dehydrogenase (LDH) from astrocytes and cell viability or survival 1 h after OGDR. Interestingly, after 3 or 5 h OGDR, PJ34 significantly reduced LDH release and percentage of PI-positive cells and increased cell viability, and simultaneously increased the caspase-dependent apoptotic rate. The intervention timing study demonstrated that an earlier and longer PJ34 intervention during reperfusion was associated with more apparent protective effects. In conclusion, earlier and longer PJ34 intervention provides remarkable protective effects for astrocytes in the "ischaemic core" mainly by reducing oncosis of the astrocytes, especially following serious OGDR damage.
