Objective:To observe the clinical efficacy of acupuncture with medication for post-stroke depression.Methods:A total of 96 patients with post-stroke depression were randomized into an observation group and a control group,with 48 cases in each group.The control group was treated with oral fluoxetine hydrochloride capsules,and the observation group was treated with acupuncture on the basis of the treatment of the control group.After 6 months of treatment,the traditional Chinese medicine (TCM) symptom scores,and Hamilton depression scale (HAMD) component scores and total scores of the two groups before and after treatment were observed,and the clinical efficacy and adverse reaction rate were compared between the two groups.Results:The total effective rate was 95.8％ in the observation group and 83.3％ in the control group,and the difference between the two groups was statistically significant (P＜0.05).After treatment,the intra-group differences in TCM symptom scores and HAMD score of both groups were statistically significant (all P＜0.01).In the observation group,the scores of indifferent expression,emotional restlessness,and sentimentality in the TCM symptoms were statistically different from those in the control group (all P＜0.01).The scores of desperate factor and sleep disorder factor and total score in HAMD in the observation group were significantly different from those in the control group (all P＜0.01).The incidence of adverse reactions was 6.3％ in the observation group and 4.2％ in the control group,and the difference was not significant between the two groups (P＞0.05).Conclusion:Acupuncture plus medication is an effective method for post-stroke depression,and it can further improve the patient's bad mood.

Background The dosage of verteporfin photodynamic therapy (PDT) for central exudative chorioretinopathy(CEC) depends on the calculation formula of Treatment of Age-related Macular Degeneration with Photodynamic Therapy Study Group(TAP)and Verteporfin in Photodynamic Therapy Study Group(VIP).Some local adverse responses or normal tissue damage have been noted under the standard dose of verteporfin during the treatment of CEC.So it is necessary to explore an appropriate therapeutic dosage of verteporfin.Objective This clinical study aimed to observe and compare the clinical efficacy and safety of different doses of verteporfin PDT for CEC.Methods Ninety eyes of 90 patients with CEC were enrolled in this study with the approval of the Ethic Commission of Affiliated Second Hospital of Nanchang University.Written informed consent was obtained before PDT.The patients were randomly divided into standard dose group,half dose group and 1/3 dose group.All of the patients received PDT.Standard dose(6 mg/m2),3 mg/m2 or 2 mg/m2 of verteporfin was applied in the three groups respectively,with the laser intensity 50 J/cm2.The patients were followed-up for 3 months.Repeat treating regimen was performed in the same way in the patient with fundus fluorescein leakage after initial PDT.Results The BCVA(logMAR) value was 0.44±0.36 after PDT in the standard dose group.Visual acuity improved in 20 patients (66.67％),stabilized in 8 patients(26.67％)and decreased in 2 patients (6.67％).The BCVA showed a significant difference between the preoperative and postoperative BCVA (t =6.719,P =0.000).CNV disappeared in 19 patients (63.33％),obviously improved in 7 patients (23.33％),partially disappeared in 3 patients (10.00％) and unchanged in 1 patient (3.33％).The central fovea thickness (CFT)value was significantly declined in postoperation compared with preoperation (t =5.758,P =0.000).Eight patients received secondary PDT with the recurrence rate 26.67％.In the half dose group,visual acuity improved in 18 patients(60.00％),stabilized in 11 patients(36.67％)and decreased in 1 patient (3.33％).CNV disappeared in 16 patients (53.33％),obviously improved in 8 patients (26.67％),partially disappeared in 5 patients (16.67％) and unchanged in 1 patient (3.33 ％).Significant difference was seen between the preoperative BCVA and postoperative BCVA(t=8.294,P =0.000).The decrease of C FT was significant in postoperation(t =8.493,P =0.000).Ten patients received secondary treatment with the recurrence rate 33.33％.In 1/3 dose group,visual acuity improved in 8 patients (26.67 ％),stabilized in 12 patients (40.00％),decreased in 10 patient (33.3％).CNV disappeared in 8 patients (26.67％),obviously improved in 8 patients (26.67％),partially disappeared in 6 patients (20.00％) and unchanged in 8 patient (26.67％).There was no significant difference between the preoperative BCVA and postoperative BCVA (t =0.536,P =0.596).The difference between preoperative CFT and postoperative CFT was insignificant(t =0.942,P=0.354).Fourteen patients received secondary PDT and 8 patients received three times with the recurrence rate 73.33％.Conclusions 3 mg/m2 verteporfin PDT for CEC shows a similar clinical efficiency and safety to 6 mg/m2 verteporfin.3 mg/m2 verteporfin PDT can decrease cost,but the effect of 2 mg/m2verteporfin PDT is not satisfacted.

Background Researches showed that the content of nitric oxide (NO) and nitric oxide synthetase (NOS) increases in blood,aqueous humor and tear of cataract patient.But the function of NO and NOS in cataract formation is still elusive.Objective The aim of this study was to explore the prevention and treatment effect of NOS inhibitor,1-nitro-arginine methyl ester (L-NAME),on galactose cataract.Methods Sixty clean three-week-old Wistar rats were equally and randomly divided into 3 groups.0.9％ Normal saline solution (30 ml/kg) was subcutaneously injected every day for 30 days in the rats of the control group,and 50％ of D-galactose solution (30 ml/kg) was used in the rats of the model and L-NAME group at the same way.L-NAME eye drops was simultaneously administered in the L-NAME group 3 times per day for 30 days.The eyes of the rats were examined under the slit lamp in 10,20 and 30 days,and the degree of lens opacification was scored.Lenses of the rats were obtained at the end of this experiment for the detect of NO,NOS contents.Flow cytometry was used to assay the caspase-3 level of rat lens.Repeated measurement two factor analysis of variance was used to analyze the difference of lens opacification scores in different groups and different time points,and one-way ANOVA was used to analyze the differences of NO,NOS and caspase-3 contents in lens among the groups.Results Lens opacification appeared in 10 days after injection of 50％ D-galactose solution in the rats of the model group and L-NAME group.Lens opacification score was higher among the different groups and different time points (Ftime =435.251,P =0.000 ;Fgroup =395.120,P=0.000).NO content in the lens was (0.45±0.15) μmol/g,(2.67 ± 0.47) μmol/g and (1.68±0.34) μmol/g in the control group,model group and L-NAME group,showing a significant difference (F=58.872,P=0.000).The NOS contents in the lens was (0.0160±0.0020) U/ml,(0.0370±0.0040) U/ml and (0.0270±0.0010) U/ml in the control group,model group and L-NAME group,showing a significant difference (F =66.174,P=0.000).Caspase-3 contents in the lens was (339.4 ± 37.9),(697.7 ± 46.5) and (650.7 ± 53.1),Showing a significant difference among them (F =100.005,P =0.000).Conclusions The increase of NO,NOS and caspase3 levels are associated with lens opacification.Topical administration of L-NAME eye drops can down-regulate NOS content in lens,reduce the NO formation and inhibit the apoptosis of lens epithelial cells.

This article was aimed to study the factors associated with sleep quality of anger-out and anger-in population based on the frequent pattern-tree (FP-Tree) growing algorithm with data mining. The algorithm of structuring frequent model FP-tree and mining frequent itemsets were designed. The database information scanned was recorded by using FP-Tree growing algorithm through state-trees. The frequent itemsets met minimum support required was generated through reducing the search space of project sets and scanning database only one. The data mining of all factors associated with emotional diseases was actualized. The results showed that factors associated with sleep quality of anger-out and anger-in population were disturbance in respiration, cough or snoring, feeling cold, hot or nightmares. The total time for program analysis was 2 seconds. It was concluded that data mining algorithm based on FP-Tree frequent itemsets can effectively realize the useful information receiving from factors associated with emotional diseases.

Objective To investigate risk factors for postoperative delirium in elderly patients with hip fractures and determine whether the delirium can influence the outcome of hip fracture.Method A retrospective case control study was performed for 521 patients (≥60 years) with hip fractures treated surgically from January 2012 to December 2014.There were 170 males and 351 females, with the age of (79.3±8.3)years.Confusion assessment method (CAM) was applied to diagnose delirium after surgery, and the subjects were divided into delirium group (n=159) and control group (n=362) according to the presence of delirium.Univariate and multivariate analyses were performed to identify the riks factors for postoperative delirium, including age, gender, comorbidities, body mass index, American Society of Anesthesiologists (ASA) classification, type of fracture, haemoglobin, PaO2, albumen, type of anesthesia, type of anesthesia, amount of bleeding, time between admission to surgery, length of operation, type of operation and amount of blood transfusion.Perioperative complications and mortality within 1 year after operation were compared between the two groups.Results Univariate analysis revealed dementia, ASA classification, haemoglobin, PaO2, albumen, interval between admission to surgery, anesthesia method, operation time, and surgery methods were risk factors for postoperative delirium incidence (P<0.05).While multivariate analysis showed only dementia (OR=6.211, 95%CI 2.482-23.498), long interval between admission to surgery (OR=3.505, 95%CI 1.478-6.342), arthroplasty (OR=2.015, 95%CI 1.783-3.481), and PaO2≤60 mmHg (OR=2.766,95%CI 1.783-5.039) were the significant risk factors for postoperative delirium after hip surgery in the elderly.Incidences of lung infection, wound infection, cardiovascular events, cerebrovascular events and deep venous thrombosis in delirium group were higher than those in control group, but only incidences of lung infection and wound infection reached significant differences (P<0.05).Mortality in delirium group was higher than that in control group within 1 year after operation, but there was significant difference only within 3 months after operation (P<0.05).Conclusions Incidence of delirium is high after hip fracture surgery in the elderly.Dementia, long interval between admission to surgery, arthroplasty and PaO2≤60 mmHg are significant risk factors for postoperative delirium incidence, and the delirium patients are associated with high early mortality.

ObjectiveTo determine the effect of telmisartan on the levels of serum adiponectin and C-reactive protein(hs-CRP)in elderly hypertensive patients with unstable angina pectoris. MethodsOne hundred and twenty elderly hypertensive patients with unstable angina pectoris were randomized into two groups, telmisartan(n=60) and perindopril(n=60) groups.The levels of hs-CRP,adiponectin, lipid factors, fasting plasma glucose (FPG), insulin and insulin sensitivity index (ISI) were measured before and 6 months after telmisartan and perindopril treatments.ResultsAt the end of 6 months, the telmisartan group showed more reduction in plasma levels of hs-CRP and more increment in serum adiponectin concentrations and ISI significantly. The frequency of cardiovascular events was significantly lower in the patients of the telmisartan group than that of the perindopril group.ConclusionsCompared with perindopril, telmisartan significantly decreases plasma levels of hs-CRP and increases serum adiponectin concentrations in elderly hypertensive patients with unstable angina pectoris. It also significantly decreases the frequency of cardiovascular events in these patients.
