Objective:To discuss the effect of amlodipine combined with atorvastatin in the treatment of elderly patients with acute cerebral infarction hypertension. Methods:Totally 86 cases with acute cerebral infarction hypertension were randomly divided into the treatment group (43 cases) and the control group (43 cases). The control group received amlodipine 5mg, po, qd, and the treatment group was given atorvastatin 20mg additionally, po, qd. After the one-month treatment, the efficacy of the two groups was studied and compared, and the changes in neural function defect scale, blood pressure, blood lipids and CRP were also investigated. Results:Af-ter the treatment, the total effective rate and the total effective rate of antihypertensive effect in the treatment group were both signifi-cantly higher than those in the control group (P<0. 05). The neurological deficit scores of the two groups were significantly higher than those before the treatment (P<0. 05), and those of the observation group was significantly higher than those of the control group (P<0. 05). The blood pressure of the two groups was both decreased after the treatment(P<0. 05), and the decrease in the treat-ment group was more significant (P<0. 05). TC, TG, LDL-C and CRP levels of the two groups had significant decrease after the treatment (P>0. 05), and those in the treatment group was significant lower than those in the control group (P<0. 05). Conclu-sion:Amlodipine combined atorvastatin in the treatment of elderly patients with acute cerebral infarction hypertension shows significant effect with low incidence of adverse drug reaction, which is worthy of wider application.

0.05), but each gene expression level was higher in schizophrenic or siblings than in normal controls(P0.05), and the correlation between the gene expression levels of IL-1? and TNF-? were significant in all groups(r=0.847 or 0.942, P

Objective To evaluate the efficacy and safety of different doses of prednisone combined with cyclosporine A(CSA) on the treatment of idiopathic membranous nephropathy (IMN). Methods The data of 64 patients with nephrotic syndrome (NS) diagnosed as IMN by renal biopsy were retrospectively analyzed. Median follow?up time was 10 (7, 19) months. The subjects were divided into 2 groups according to different prednisone dosage. Thirty?two cases were in the low?dose group:prednisone 0.15 mg·kg-1·d-1+CSA, and 32 cases in the moderate?dose group:prednisone 0.4?0.5 mg· kg-1·d-1+CSA. Clinical and laboratory data were collected at baseline, 1, 3, and 6 months after treatment. During follow?up, cumulative recurrence rate and adverse reactions after treatment were recorded. Results Serum albumin (sALB) were significantly increased and 24 h urinary protein (24hUP) significantly decreased after treatment for 1, 3, 6 months compared with baseline data in the two groups. Serum creatine (Scr) increased after treatment with time. The elevation of sALB and the reduction of 24hUP in the moderate?dose group were higher than that of low?dose group at 6 months after treatment (P<0.05). The effective rate of the low?dose and moderate?dose group was 65.6% and 87.5% at 6 months after treatment, respectively (χ2=4.267, P=0.039). Comparison of different doses of CSA in two groups at 6 months after treatment, in low?dose group: the effective rates of CSA<3 mg· kg-1·d-1 and >3 mg·kg-1·d-1 subgroup were 76.5% and 53.3%, respectively (P=0.296); In moderate?dose group:the effective rates of CSA<3 mg·kg-1·d-1 and>3 mg·kg-1·d-1 subgroup were 89.5%and 84.6%, respectively (P=0.077); there were similar effects in patients treated with different dose CSA in the two groups. About 20.4% of the total patients relapsed when followed up for 18 months (low dose group vs moderate?dose group: 9.5% vs 28.6%, P=0.136), which most occurred after prednisone withdrawal or during the reduction of cyclosporine. Renal function decreased in 57.8% patients (low dose group vs moderate?dose group:50%vs 65.6%), mainly in the elderly (9/11) and the long course of treatment of CSA. There was no significant difference on adverse reactions between the two groups (P>0.05). Renal function in patients with high Scr or high blood trough concentration of cyclosporine was difficult to fully recover. Conclusions Remission rate is lower in low?dose prednisone combined with cyclosporine than the moderate?dose group in the treatment of IMN for 6 months. The recurrence rate of IMN or the incidence of adverse reactions are similar between the two groups. Induction therapy of IMN with cyclosporin<3 mg·kg-1·d-1 is safe and effective. The incidence of renal function reduction in the elderly is high, and the renal function is difficult to restore in patients with Scr exceeding normal upper limits.

Objective To study the effect of relaxation therapy on sleeping quality of patients with post cran- iocerebral traumatic syndrome. Methods 90 cases with sleep disorders were randomly divided into the treatment group and the control group. The control group was given routine care and the treatment group was given relaxation therapy combined with routine care. Take pittsburgh sleep quality index (PSQI) as evaluation criteria. Results There was significant difference between the two groups( P < 0.01 ). Sleep quality was more improved by relaxation therapy in the experimental group than that of the control group. Conclusion Relaxation therapy can effectively im- prove sleep quality in patients with post craniocerebral traumatic syndrome.

OBJECTIVE To analyze the correlation factors of nosocomial infection in patients after receiving craniocerebral operation.METHODS Totally 388 hospitalized patients after receiving craniocerebral operation from Jan 2006 to Dec 2006 were studied retrospectively.RESULTS From them 45 pateints were suffering from nosocomial infection and total incidence of nosocomial infection was 11.59%.Among them,60.0% was lower respiratory tract infection,11.11% was surgical wound infection and 8.89% was upper respiratory infection.Aging,length of stay and invasive operation(deep vein needle detaining,trachea incision,tracheal intubation,urinary canal and drainage tube dwelling) were the main correlation tactors.CONCLUSIONS Minimizing invasive operation and early removing various kinds of dwelling tubes,using antibiotics correctly,improving hospitalizd environment and strengthening wards management are the measures to reduce nosocomial infection according its correlation factors.

ObjectiveTo study the effect of rehabilitation on psychological health in first schizophrenic patients. Methods86 patients were divided into observation group and control group equally. Patients in both groups received medical treatment and routine health education. Patients in observation group received rehabilitation in addition. They were assessed with Symptom Checklist-90 （SCL-90）before and 8 weeks after treatment.ResultsAfter treatment, the scores of SCL-90 in both groups reduced significantly （P<0.05）, and less in the observation group than in the control group (P<0.01).ConclusionRehabilitation can improve the psychological health for patients with first schizophrenia.

Objective To investigate the effect of gonadotropin-releasing hormone analogue(GnRH-a) on pregnancy outcome in patients with endometriosis infertility after laparoscopic surgery.Methods Two hundred and twenty two patients treated with laparoscopic surgery for endometriosis infertility in Jiaxing Maternal and Child Health Care Hospital between January 2010 and December 2012 were enrolled and 184 patients completed the study.Patients were randomly assigned to two groups:110 patients in GnRH-a group received long-acting GnRH-a (3.75 mg injection every 28 d for 3 times) before trying to conceive,74 patients in control group were directly trying to conceive for 1 to 36 months.According to endometriosis fertility index (EFI),patients were further subgrouped:GnRH-a group 1 (EFI scores =6-10,n =83),GnRH-a group 2 (EFI scores =0-5,n =27),control group 1 (EFI scores =6-10,n =55) and control group 2 (EFI scores =0-5,n =19).The cumulative pregnancy rate (CPR) and abortion rate were compared among groups and subgroups.Results The patients were followed up for 1 to 36 months after trying to conceive,with a median follow-up time of 14 months.The total CPR was 62％ (114/184),the median time for gestation was 11 months.Within the first 6 months after operation,the CPR in GnRH-a group and its subgroups were lower than those in corresponding control groups,with significant difference between GnRH-a group and control group [9％ (10/110) vs.32％ (24/74),x2 =16.00,P ＜0.01],GnRH-a group 1 and control group 1 [8％ (7/83) vs.38％ (21/55),x2 =18.10,P ＜0.01].Within 12 months,24 months and 36 months,the CPR in GnRH-a group and its subgroups were all higher than those in corresponding control groups [66％ (55/83) vs.49％ (27/55),x2 =4.05,P ＜ 0.05].The pregnant rate within 12 months in GnRH-a group was 88％ (63/72),which was not significantly different to that in control group [76％ (32/42),x2 =2.44,P ＞ 0.05].Kaplan-Meier analysis showed that there were no significant difference in CPR between GnRH-a group and control group,GnRH-a group 1 and control group 1,GnRH-a group 2 and control group 2 (all P ＞ 0.05).The median time for gestation in GnRH-a group and its subgroups were shorter than those in corresponding control group.The median time for gestation in GnRH-a group was 10 (95％ CI:8.2-11.8) months and that in control group was 17 (95％ CI:1l.8-22.1) months.The abortion rate in GnRH-a group and control group was 11％ (7/72) and 26％ (11/42),respectively (x2 =4.34,P ＜ 0.05).Conclusion Administration of GnRH-a for 3 cycles can improve postoperative pregnancy rate within 1 year and reduce the abortion rate for endometriosis infertile patients after laparoscopic surgery especially for these with strong fertility.

Objective To investigate the relative risk factors for early abortion among singleton pregnancies after assisted reproductive technology (ART) treatment. Methods A retrospective analysis was performed on 1636 singleton pregnancies, including 196 early abortion cases and 1195pregnancies with live birth after exclusion of those lost cases during follow-up, or complicated with uterine deformity, or oocyte receptor, or late abortion, or incomplete medical record, following in vitro fertilization(IVF)/ intracytoplasmic sperm injection (ICSI) treatment and the risk factors of early abortion were investigated. The early abortion rate was also compared between fresh IVF/ICSI group and frozen embryo transfer (FET) group (n=386). Results Multivariate Logistic regression analysis indicated that elder women (OR= 1. 143,95%CI: 1. 096-1. 196) and patients with polycystic ovarian syndrome (OR = 4. 309,95 % CI : 2. 564-7.243) were risk factors of spontaneous early abortion,and high mean score of transferred embryos (MSTE) (OR = 0. 808, 95% CI: 0. 717-0. 912) and endometrial triple-lined pattern on the day of human chorionic gonadotropin (hCG) administration (OR=0. 431, 95% CI: 0. 243-0.764)were protective factors. Significant difference were found in the maternal age [(32.22±4. 10) yrs vs (30.28±3. 66) yrs],the duration of infertility [(5. 90±4.26) yrs vs (5.20 ± 3. 32) yrs], basal serum follicle-stimulating hormone (FSH) level [(6. 35 ±2.30) mIU/ml vs (5.95±2.12) mIU/ml], number of transferred embryos (2. 31±0. 51) vs (2. 18±0.49), serum estradiol level on the day of hCG administration [(2467. 1 ± 1588. 8) pg/ml vs (2934. 5 ±1785.2) pg/ml] and MSTE (7.03 ±1.35 vs 7.74 ± 1.25) between the abortion group and livebirth group (all P＜0. 05). The spontaneous abortion rate was higher in the FET group than in the fresh embryo transfer group [17. 36%(67/386) vs 13.02% (213/1636), χ2 =4. 296, P=0. 023].Conclusions Women at elder age, or with long duration of infertility, high basal FSH level,polycystic ovarian syndrome, low MSTE, non-triple-lined pattern of endometrium on the day of hCG administration are at risk of spontaneous early abortion in pregnancies after ART. The rate of spontaneous abortion is higher in FET group than in fresh IVF/ICSI group.

Objective To explore the clinical correlation of the variation of plasma homocysteine (HCY), melatonin (MLT) and ulceative colitis (UC). Methods The clinical data of 112 UC patients was collected, and 110 normal healthy persons as control. The level of plasma HCY and MLT was detected by high pressure liquid chromatography-fluorescence detection (HPLC-FD) method. The level of plasma folate ( FA) and vitamin B12 was detected by enzyme-linked immunosorbent assay (ELISA) method. The correlation of these four indexes and UC was analyzed. Results The serum level of HCY in UC patients was significantly higher than that in normal healthy persons [(11. 27± 7.26) μmol/L vs (8. 19±4. 81) μmol/L, P = 0. 000]. The serum level of MLT in UC patients was significantly lower than that in normal healthy persons [(49. 06 + 31. 40) pg/ml vs (64. 28±41. 16) pg/ml,P=0. 008]. The serum level of FA in UC patients was significantly lower than that in normal healthy persons [(7. 64 + 1.95) nmol/L vs (9. 14 + 1.23) nmol/L, P = 0. 005]. The serum level of vitamin B12 in UC patients was significantly lower than that in normal healthy persons [(108. 64 ±32. 22) pmol/L vs (112. 64±33. 33) pmol/L, P = 0. 004]. There was no correlation between plasma HCY, MLT and UC disease activity degree, range, disease duration, erythrocyte sedimentation rate (ESR), or C reactive protein (CRP) in UC patients. There was no significant correlation between MLT and HCY in UC patients. Conclusions The serum level of HCY is higher in UC patients than that in normal control, and MLT is lower than that in normal control. However there is no significant correlation between them.
