Objective To investigate the relationship between estrogen replacement therapy and female patients with Alzheimer's risk. Methods We searched the PubMed, Springer, CBM, CNKI, VIP database for studies on the es-trogen replacement therapy and women with Alzheimer's disease, retrieval time from database to 2012 December. We evaluated the methodological quality of the included studies, used RevMan 5.0 software to analyze the extracted data. Results We found seven case-control studies which included 1392 patients and 2719 controls. The meta analysis re-sults show that the proportion of estrogen replacement therapy in AD group is significantly lower than that of the con-trol group, the difference has statistically significant [OR=0.68, 95%CI(0.50,0.90), P=0.01]. Conclusions estrogen re-placement therapy has effects on female patients with Alzheimer's disease, and is a protective factor.

Objective To construct the plasmid that can produce long,double-stranded RNA and identify nonspecific apoptosis induced by long, double-stranded RNA in human osteosarcoma cells. Methods Plasmid pCI-neo-dsRNA was constructed by two promoters driven DNA sequence based on nontoxic, completely exoteric gene EGFP from the head and the end simultaneously to synthesize sense and antisense RNAs. Human osteosarcoma cells MG63 were transfected with pCI-neo-dsRNA and 48 h later the transfected cells were assessed by Apoptosis Detection System, FCMand MTT method. Results Plasmid pCI-neo-dsRNA was constructed successfully, MTT measurement showed that the absorbance of cells decreased gradually with the increase of plasmid pCI-neo-dsRNA dose(0.05 ?g, 0.10 ?g, 0.15 ?g, 0.20 ?g,0.25 ?g,0.30 ?g). MG3 transfected with pCI-neo-dsEGFP presented a great amount of irregular green fluorescence that indicated cell apoptosis. As the quantity of dsRNA increased, the percent of apoptosis cells also raised. While the dose of pCI-neo-dsEGF was 3.0 ?g, the apoptotic results of pCI-neo-dsEGF in MG3 were similar to that of 5-FU. Conclusion Long, double- stranded RNA could trigger human osteosarcoma cell apoptosis and the further research on using long, double-stranded RNA in osteosarcoma gene therapy can be done based on this theory.

Objective To identify the glycometabolism features ofC57BL/Ksj db/+ mice at gestational period and provide the evidence for the mice used as the animal model of gestational diabetes mellitus (GDM).Methods Ten C57BL/Ksj db/+ female mice and ten wild female mice were randomly selected and mated with wild male mice respectively.Day 3 before mating,days 6,11 and 17 of pregnancy,and day 6 after delivery represented pre pregnancy,early-pregnancy,mid-pregnancy,late-pregnancy and post-pregnancy periods,respectively.The levels of glucose tolerance and fasting insulin of female mice were compared at progestation,different gestational periods and puerperium between the two groups.Days 6,11,14,17 and 20 (before labor) of pregnancy served as five time-points of pregnancy,leptin levels of female mice of the two groups were dynamically monitored during pregnancy,and analyzed at different gestational ages.The data were analyzed by Tukey test of one-way ANOVA.Results (1) Compared with the normal pregnant mice,the levels of glucose tolerance of C57BL/Ksj db/+ female mice were significantly decreased,while the levels of fasting insulin were dramatically increased with the progression of pregnancy [day 6 of pregnancy,(8.6 ± 0.6) mU/L vs (7.5 ±1.1) mU/L; day 11 of pregnancy,(9.8±0.6) mU/L vs (8.5± 1.1) mU/L; day 17 of pregnancy,(10.4±0.8) mU/L vs (9.9±0.5) mU/L; t=1.859,4.056 and 3.078,P=0.085,0.000 and 0.000] and recovered to the pre-pregnancy level after delivery.(2) The level of leptin in serum of C57BL/Ksj db/+ pregnant mice was significantly higher than that at non-pregnant period [pre-pregnancy and days 6,11,14,17 and 20 of pregnancy:(911.0±238.8) ng/L,(1 342.2± 132.3) ng/L,(1 821.9±238.2) ng/L,(1 816.3± 142.3) ng/L,(1 752.4± 126.6) ng/L,and (1 926.4±61.6) ng/L,respectively; t=3.887,8.210,8.161,7.585 and 9.153,P=0.005,0.000,0.000,0.000 and 0.000],but showed no apparent change with the gestational ages after mid-gestation.Conclusion Changes of glycometabolism and the levels of leptin and insulin of C57BL/Ksj db/+ pregnant mice during pregnancy are similar to those of GDM patients,the levels of fasting insulin are dramatically increased with the progression of pregnancy,and return to normal after delivery,the level of leptin is higher than that at non-pregnant period,but is not correlated with the gestational ages.C57BL/Ksj db/+ pregnant mice can be used as the animal model of GDM.

Objctive To search for the therapeutic method of children's nephrotic syndrome.Methods Sixty-six cases oe children's nephrotic syndrome were randomly divided into 2 groups,impulsion group (34 cases) and control group (32 cases). Dexamethasone (1．5~3 )/mg (kg?d) added into (100~150)ml 10%GS solution, intravenous drip in impulsion group, one time a day, totat 3 days, the fourth day stoped. The fifth day started again and used one time evcry two days, total 6 times. Prednisone(1．5~3)mg/(kg?d) were taken next day and total 4 weeks, then grandually decreased the dose. Only prodnisone was used in control group, the method and dose were the same as impulsion group.Results Complete remission. partial remission inefficacy ere 23, 7 and 4 cases respectiye1y in impulsion group and 22, 5 and 5 cases respectively in control group, the effective rates of the 2 group are 88．23%and 84．38% (P＞0．05). The times of state of illness stabilization are respectively 11．3?7．2 and 10．48?6．34 months in the 2 groups. The side effect of impulsion group is bigger than that of control group.Conclusion Children's primary nephrotic syndrome should be treated for 8 weeks by routine hormone induction therapy, if no remission, impulsion therapy could be used.

OBJECTIVETo compare the efficacy differences between fire needling therapy and oxycycline tablets for the treatment of moderate to severe acne vulgaris.

METHODSSixty cases of moderate to severe acne vulgaris were randomly divided into a fire needling group and a medication group, 30 cases in each one. The pricking method of fire needling at Ashi points around damaged skin was applied in the fire needling group, once every five days for totally 4 times. The oral administration of oxycycline tablets, 100 mg, was applied in the medication group, twice daily for 20 days, also external application of adapalene gel before sleep was adopted. The fading time of skin damage, including papule, pustule, nodule and cyst in the two groups was recorded and clinical efficacy was compared. After the treatment, two-month follow-up was performed to observe the recurrence rate in the two groups.

RESULTSThe curative rate was 69.0% (20/29) in the fire needling group, which was statistically different from 40.0% (12/30) in the medication group (P < 0.05). The fading time of each type of skin damage in the fire needling group was shorter than that in the medication group [papule: (2.67 +/- 0.66) d vs (4.36 +/- 0.61) d; pustule: (2.47 +/- 0.57) d vs (4.27 +/- 0.55) d; nodule: (7.76 +/- 1.06) d vs (9.88-1.30) d; cyst: (11.81 +/- 1.54) d vs (14.79 +/- 0.89) d, all P < 0.05]. The recurrence rate was 46.4% (13/28) in the fire needling group, which was not significantly different from 44.0% (11/24) in the medication group (P > 0.05).

CONCLUSIONThe acne vulgaris could be fast and effectively treated by fire needling therapy, which has shorter fading time than oxycycline tablets. However, the preventive effect is not different between the two theraies.

Abstract? AIM: To analyze the ocular manifestations of meningiomas in the trigone of the lateral ventricle, discuss the relevant factors of visual impairment in these patients and things need attention clinically.?METHODS:Retrospectively study on the clinical data of 90 eyes in 45 patients diagnosed of trigonal meningiomas treated at Beijing Tian Tan Hospital from October 2011 to October 2015.Preoperative examinations including visual acuity, optic disc findings, visual field, size of tumors and other change in MRI were analyzed.?RESULTS: Patients'age was 12-68 years old ( mean 41.7 ±13.7 years ). Male/female ratio was 1 ∶4.6. Decreased visual acuity occurred in 18 eyes.Optic disc edema was found in 24 eyes and optic disc pale in 6 eyes. Fourty -seven eyes had visual field defect, mostly homonymous hemianopia or defect. The maximum diameter of tumors was 2.1-9.6cm (4.8±1.7cm).Range of tumor volume was 3.02-193.2cm3(48.3±47.8cm3).A positive correlation of preoperative visual field defect was found with tumor volume, tumor maximum diameter, and brain midline shift respectively. While the preoperative visual field defect was not found any correlation with age, gender, course, and the enlargement of the ventricle and the edema of the tissue around the tumors. After Mann-Whitney U test, the differences on tumor volume, the maximum diameter of tumors, and brain midline shift between the two groups were significant.? CONCLUSION: Patients with trigonal meningiomas often have ocular signs and symptoms.The major reason of visual field defect is the damage of optic radiation around the tumor.The specific position of injured optic radiation determines the type and extent of visual field defect.Both ophthalmologist and neurosurgeon should pay attention to tumors nearby posterior visual pathway. Doing neurophthalmology examinations for these patients and realizing the position between the tumor and posterior visual pathway will be helpful and necessary in surgical planning.

Objective To evaluate the soft tissue profile in adults with unoperated isolated cleft palate. Methods Twenty patients older than 16 years(median age,18.4) with unoperated isolated cleft palate were enrolled.Soft tissue lateral cephalograms were traced and compared with those of cleft operated patients and class-Ⅰocclusion individuals.The results of various measurements were analyzed with ANOVA by SPSS11.5. Results In adults with unoperated isolated cleft palate,there was restriction at the top of the upper lip,and the antelabrum of upper lip and the lower lip were found normal. Conclusion The soft tissue profile in adults with unoperated isolated cleft palate exhibits almost the same characteristics as the corresponding hard tissue,and there is covering over effect of the soft tissue to some extent.

Post-stroke fatigue (PoSF) is an independent pathologic symptom after stroke which negatively influenced activities of daily living (ADL) and quality of life (QOL) of the stroke patients. PoSF is irrelevant to depression, age, state of the illness, etc. PoSF should be assessed appropriately and alleviated by medicine, diet, sleep, exercise, and health education, etc.

Objective To observe the efficacy and adverse reaction of raltitrexed combined with irino-tecan as first-line chemotherapy for recurrent or metastatic gastric cancer.Methods From January 201 4 to March 201 5,39 patients of recurrent or metastatic gastric cancer who received treatment in the First People′s Hospital of Zhangjiagang of Jiangsu Province were collected.All patients received raltitrexed (3.0 mg/m2 , 1 5 min intravenous drip)on the first day and irinotecan (1 80.0 mg/m2 ,90 min intravenous drip)on the first day.One cycle lasted 21 days.The efficacies were evaluated every 2-cycle.Adverse reactions were evaluated every cycle.Results The efficacies and adverse reactions could be evaluated in 39 patients.The study received 0 complete remission,1 6 partial remission,1 1 stable disease,1 2 progression disease.The objective response rate was 41 .03% (1 6 /39).The disease control rate was 69.23% (27 /39).The median overall sur-vival time was 9.3 months (95%CI:8.8-1 1 .1 months).The median progression-free survival time was 6.0 months (95%CI:5.1 -6.8 months).The adverse reactions were mainly neutropenia,anemia,liver dysfunc-tion,the incidence of them were 35.90%,33.33% and 28.21 % respectively.Conlusion Raltitrexed com-bined with irinotecan as first-line chemotherapy for recurrent or metastatic gastric cancer acquires an definite efficacy,and the adverse reactions can be tolerated,which is worthy of further clinical research.

Objective To study the sedation and amnesia of midazolam in patients with different ages of lumbar epidural anesthesia . Methods From January to July 2015, 235 patients in the first affiliated of xian jiaotong unniversity,who were implemented abdominal surgery under combined spinal epidural anesthesia and American Society of anesthesiologists (ASA) grade was I-II , were divided into three groups:young group (n=70); middle-aged group (n =82); elderly group (n =83).Intraoperative continuous monitoring of respiratory and circulatory function index,and recorded MAP,SpO2, HR before and 5, 15, 30 min after injection.ResuIts MAP, HR and SpO2 of three groups were compared with the same time points pre-and post used of midazolam, there was no significant difference among indicators.; Compared with the same group at different time points, MAP(FYG =9.2547,FMG =12.8181,FOG =17.77)和 SpO2 (FYG =190.3835,FMG =196.2393,FOG =270.5609),there were significant difference.The difference was not statistically significant between HR group and the same group at different time points and forgetting degree and sedation score , but compared with OG,there were significant difference(P<0.05).The total number of adverse reactions in YG group and MG group was less than that of OG group(X2 =11.2516,X2 =10.4491, P<0.05).ConcIusion The effect of the same dose of midazolam on sedation and amnesia in patients with different ages of lumbar epidural anesthesia is different, and the degree of the effect of the elderly patients is significant,but will produce more adverse reactions.Therefore, in the combined spinal epidural anesthesia,it is necessary to consider the patient's individual differences, rational use of sedative and narcotic drugs.
