Objective To study the effect of noise on the ability of learning and memory of mice,and observe the effect of herba Houttuyniae injection on the change of the ability of learning and memory in noise condition, and then analyses the mechanisms. Methods To choose suitable mice and divide into groups, applying Y-maze and colorimeter to determine the content of MDA and the enzyme activity of SOD, AChE and NOS of mice brain. Results Learning group in Y-maze, noise cause the ability of noise group (12.1±1.20) decrease(P＜0.01) compared with the control group(15.1±1.45), but herba Houttuyniae injection can reverse the ability of the mice, the correct frequency is much higher(P＜0.01)in herba Houttuyniae group(14.9±1.60). The results is same in the memory group, in Y-maze, noise cause the memory ability of noise group (5.20±1.40) decrease(P＜0.01) compared with the control group(6.30±1.32), but herba Houttuyniae injection can reverse the memory ability of the mice, the correct frequency is much higher(P＜0.01)in herba Houttuyniae group(6.10±1.10). Either learning or memory group mice, noise can decreased the activity of SOD and NOS of mice brain(P＜0.01), but the content of MDA and the ability of AChE elevated(P＜0.01). herba Houttuyniae injection can change the effect of noise to mice, the activity of SOD and NOS of mice brain elevated(P＜0.01) and the content of MDA and the ability of AChE decreased (P＜0.01). Conclusion herba Houttuyniae injection can prevent the ability of learning and memory of mice which decreased by noise, and have the effect of intoxication.

Objective To investigate the relationship between 5 ,10-methylenetetrahydrofolate reductase (MTHFR) gene C677T locus polymorphism and unexplained adverse pregnancy.Methods Three hundreds and twenty pregnant women with unknown ad-verse pregnancy ≥ 2 times in the infertility department ,and obstetrics and gynecology department of our hospital from June 2014 to May 2016 were selected as the case group and 388 healthy non-abortion parous women were taken as the control group.The MTH-FR gene C677T locus polymorphism in the two groups was analyzed by using gene chip method.The differences in genotype and al-lele frequency distribution were compared between the two groups ,and the relationship between unexplained adverse pregnancy and MTHFR C677T locus polymorphism was analyzed.Results The frequency distribution of MTHFR genotype C677T C/C had sta-tistically significant difference between the case group and control group (P<0.05 ,OR=0.284).The frequency distribution of gen-otype C/T had no statistical difference between the case group and control group (P=0.400 ,OR=1.140).The frequency distribu-tion of genotype T/T had statistical difference between the case group and control group (P<0.05 ,OR=7.672).The frequency distribution of allele C and T had statistical difference between the case group and control group ( P< 0.05 ,OR= 0.304 ). Conclusion The high expression of MTHFR C677T genotype T/T may be a risk factor of unknown adverse pregnancy in child-bearing age women.

Objective To evaluate the effectiveness and safety of autologous granular fat graft applied for penile lengthening and augmentation.Methods After all the superficial ligment and 1/3-2/ 3 part of the deep suspensory-ligament had been cut off for penile lengthening,local pedicaled fasciaadipose flap was designed to fill the depression,the pre-centrifuged autologous granular fat was injected into the space beneath Buck's fascia for penile augmentation.Normal length,pulling penis length,diameter,circumference and complications were evaluated.Results 34 cases were performed and followed up for 3-18 months,both ideal length and diameter increase of penis were achieved.The differences of nomal length,pulling-length,the diameter and circumference were (2.8±0.1) cm,(2.1±0.2) cm,(0.9 ± 0.1) cm,(2.8 ± 0.1) cm,respectively.The common complications included poor wound healing in 4 cases,preputial edema and subcutaneous scleroma in 8 cases for 3 months.Conclusions Autologous granular fat graft for penile augmentation during the lengthening surgery is a reliable and effective method and easy procedure.Detail processing can decrease the complications.

Objective To evaluate the role of mitochondrial ATP-sensitive potassium (mito-KATe) channels in attenuation of cerebral ischemia-reperfusion (I/R) injury by dexmedetomidine in rats.Methods One hundred and twenty healthy male Wistar rats,weighing 290-340 g,were randomly assigned into 5 groups (n =24 each) using a random number table:sham operation group (group S) ; group I/R; dexmedetomidine group (group D) ; 5-HD (a specific blocker of mito-KATPchannel) group and 5-HD + dexmedetomidine group (group 5-HD + D).The rats were anesthetized with intraperitoneal chloral hydrate.Focal cerebral I/R was produced by 2 h middle cerebral artery occlusion followed by reperfusion.In group D,dexmedetomidine 50 μg/kg was injected intraperitoneally before ischemia and after onset of reperfusion.In group 5-HD,5-HD 30 mg/kg was injected intraperitoneally at 1 h before ischemia.In 5-HD + D group,5-HD 30 mg/kg was injected intraperitoneally at 1 h before ischemia and the other procedures were similar to those previously described in group D.Twelve rats were chosen at 24 and 48 h of reperfusion to assess the neurological deficit score (NDS).The animals were then sacrificed and brains were removed for determination of cerebral infarct size by TTC staining.Results Compared with S group,NDS and cerebral infarct size were significantly increased at each time point in the other four groups (P ＜ 0.05).Compared with group I/R,NDS and cerebral infarct size were significantly decreased in D and 5-HD + D groups (P ＜ 0.05),and no significant change was found in the parameters mentioned above in 5-HD group (P ＞ 0.05).Compared with group D,NDS and infarct size were significantly increased in group 5-HD + D (P ＜ 0.05).Conclusion Mito-KATP channels are involved in reduction of I/R-induced cerebral injury by dexmedetomidine in rats.

Wet age-related macular degeneration (AMD) is one of major causes of blindness in elder people.Intraocular injection of anti-vascular endothelial growth factor (VEGF) -A regimen has made big breakthrough for the treatment on choroidal neovascularization of wet AM D,while long-term follow-up and necessary retreatments are the key issues to remain obtained visual acuity.Multiple strategies of wet AMD have been used in following-up and retreating based on the visual acuity,optical coherence tomography (OCT),ophthalmoscope and fluorescein fundus angiography (FFA) in abroad.However,there also are major differences in the patient' s composition,treatment habits and distribution of medical sources in China from Western.So we suggest to standardize the follow-up and retreatment strategies about intravitreal injection of VEGF-A for wet AMD as to achieve a better effectiveness.OCT-guided individual follow-up and retreatment strategies should be very helpful for maintaining a long-term efficacy,minimizing the treatment time and reducing medical cost.

Background Cataract phacoemulsification combined with intraocular lens (IOL) implantation is a primary treatment for cataract.However,tear film stability and ocular surface structure are affected after surgery,especially some cataract patients with diabetes.Researches determined that tear film dysfunction is an important causative factor of dry eye.Objective This study was to investigate the change of tear film after phacoemulsification in cataract patient with diabetes.Methods A non-randomized cases-controlled study was designed.Thirty-six cataract patients with diabetes (54 eyes)and matched 32 patients (40 eyes)with age-related cataract were included in this study in Tianjin First Center Hospital from October,2010 to May,2011.Phacoemulsification and IOL implantation was performed on the all patients with the same topical eyedrops in both groups.Dry eye-related symptom was surveyed and scored by questionnaire,and tear film break-up time (BUT),Schirmer Ⅰ test(S Ⅰ t)and corneal fluorescein(FL) were examined 3 days before operation and 1 day,1 week,1month,3 months after operation.Written informed consent was obtained from each patient before entering this trial.Results The percentage with preoperative symptoms of dry eye was 36.2％ and postoperative dry eye symptoms accounted for 75.8％.Significant differences were seen in dry eye symptom score,FL score,BUT value and S Ⅰ t value between the diabetic cataract group and only cataract group as well as among 4 time points(dry eye symptom score:Fgroup =139.347,P =0.000 ; Ftime =342.741,P =0.000 ; FL score: Fgroup =14.073,P =0.000 ; Ftime =332.697,P =0.000 ; BUT value: Fgroup =28.198,P =0.000 ; Ftime =868.364,P =0.000 ; S Ⅰ t value: Fgroup =2.848,P =0.095 ; Ftime =564.017,P=0.000).FL scores of 2 groups were significantly higher in postoperation than those in preoperation (P＜0.05),and those of diabetic cataract group were significantly higher than only cataract group(P＜0.05),but no significant difference was found between postoperation 3 months and preoperation (P＞0.05).BUT was shorter in postoperation than that in preoperation in the diabetic cataract group(P＜0.05).S Ⅰ t values in postoperative 1 day and 1 week were significantly lower than in preoperation in both groups(P＜0.05).However,S Ⅰ t values returned to normal from 1 month through 3 months in both groups(P＞0.05).Conclusions Tear film dysfunction occurs after operationin cataract patient with type 2 diabetes.It is thought that cataract patient with diabetes is susceptible population of dry eye.Dry eye appears more early and severer in diabetes patients after phacoemulsification combined with IOL implantation.
