AIM:To compare the short-term and long-term curative effect between two implantation methods for treating refractory glaucoma.METHODS:A total of 150 patients with refractory glaucoma (150 eyes) were divided into Group A (treated by implantation with Ex-press glaucoma drainage device) and Group B (treated by implantation with Ahmed glaucoma valve) according to different implantation methods.Changes of intraocular pressure and anti-glaucoma drugs at different time points, the success rate of surgery, improvement of visual acuity and complications were compared between the two groups.RESULTS:The intraocular pressure of two groups at 1d, 1wk, 3, 6 and 12mo after surgery was significantly lower than that before surgery (P<0.05).The intraocular pressure of Group A at 3, 6 and 12mo after surgery was significantly lower than that of Group B, while anti-glaucoma drugs at 6 and 12mo after surgery were significantly fewer than those in Group B at the same time point (P<0.05).There were no significant differences between the two groups in 12-month success rate of operation, improvement rate of visual acuity and incidence of postoperative complications (P>0.05).CONCLUSION:The effects of implantation with Ex-press glaucoma drainage device are similar to those of implantation with Ahmed glaucoma valve in the treatment of refractory glaucoma.However, the intraocular pressure control effect of the former is better than the latter, and used anti-glaucoma drugs are fewer.

To systematically review the incidence rate of adverse drug reaction/event by Qingkailing injection. Such databases as the PubMed, EMbase, the Cochrane library, CNKI, VIP WanFang data and CBM were searched by computer from foundation to July 30, 2015. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and cross check data. Then, Meta-analysis was performed by using the R 3.2.0 software, subgroup sensitivity analysis was performed based on age, mode of medicine, observation time and research quality. Sixty-three studies involving 9,793 patients with Qingkailing injection were included, 367 cases of adverse reactions/events were reported in total. The incidence rate of adverse reaction in skin and mucosa group was 2% [95% CI (0.02; 0.03)]; the digestive system adverse reaction was 6% [95% CI(0.05; 0.07); the injection site adverse reaction was 4% [95% CI (0.02; 0.07)]. In the digestive system as the main types of adverse reactions/events, incidence of children and adults were 4.6% [0.021 1; 0.097 7] and 6.9% [0.053 5; 0.089 8], respectively. Adverse reactions to skin and mucous membrane damage as the main performance/event type, the observation time > 7 days and ≤ 7 days incidence of 3% [0.012 9; 0.068 3] and 1.9% [0.007 8; 0.046 1], respectively. Subgroup analysis showed that different types of adverse reactions, combination in the incidence of adverse reactions/events were higher than that of single drug, the difference was statistically significant (P < 0.05). This study suggested the influence factors of adverse reactions occur, and clinical rational drug use, such as combination, age and other fators, and the influence factors vary in different populations. Therefore, clinical doctors for children and the elderly use special care was required for a clear and open spirit injection, the implementation of individualized medication.

Objective To assess the damage of limbic system pathways in relapsing-remitting multiple sclerosis (RRMS) by diffusion tensor imaging (DTI) tractography.Methods DTI tractography was used to acquire fiber numbers,fractional anisotropy (FA),mean diffusivity (MD) of cingulum,fornix,and uncinate fasciculus (UF) in 20 RRMS patients (MS group) and 20 healthy volunteers (control group),and statistical analysis was performed.Results Compared with control group,lower FA value (P＜0.01) and higher MD value (P＜0.05) were found in cingulum,fornix and UF of MS group,and the fiber numbers of fornix decreased in MS group (P＜0.001).There were significant differences between the left and the right UF in fiber numbers and FA value of control group and the fiber numbers of MS group.Negative correlations were found between FA value of cingulum and UF and EDSS scores in MS group (r=-0.572,-0.665,both P＜0.05),and positive correlations were found between MD value and EDSS scores (r=0.627,0.603,both P＜0.05).Conclusion DTI tractography is valuable in assessing MS associated limbic system damage and in monitoring the clinical progression of the disease.

Objective To evaluate the quality coherence of commercial Angelicae Dahuricae Radix (Baizhi) decoction pieces. Methods The samples of 12 batches of commercial decoction pieces, 1 batch of sulphur fumigated Baizhi, and 1 batch of naturally dried Baizhi were collected. HPLC method was used to determine the fingerprints and the contents of imperatorin and isoimperatorin by C18 column (4.6 mm×250 mm, 5 μm) with a gradient mobile phase of acetonitrile-water solution system at the flow rate of 1.0 mL/min. The column temperature was set at 35 ℃, and the max plot of detection wavelength was in 210-800 nm. Similarity calculation was used to analyze the data. Results The HPLC fingerprint analysis method was established with 12 common peaks. The similarities of 12 batches of commercial decoction pieces of Baizhi were 0.840-0.973. Their similarities compared with the sulphur fumigated Baizhi were 0.672-0.908. Compared with naturally dried Baizhi, the similarities of fingerprint were 0.536-0.684. The contents of imperatorin and isoimperatorin in 12 batches of commercial decoction pieces were 0.035%-0.140% and 0.028%-0.069%, respectively. Conclusion The quality of Baizhi decoction pieces was consistent. It can be speculated that Baizhi decoction pieces were processed with sulphur fumigation.

Nitrite reductases (NiRs) are the key enzymes in the denitrification pathway of the nitrogen cycle. By the catalysis of NiRs, the nitrites are turned into nitric oxides and the nitrogen pollution is decreased in water body. NiRs are divided into two different types based on their prosthetic groups, namely heme-containing nitrite reductases (cd1-NiRs) and Copper-containing nitrite reductases (Cu-NiRs). As all know, Cu-NiRs have trimeric structures, in their each monomer, there exist two types of Cu centers that play pivotal roles as the components of electron transfer pathway in the process of catalysis. Furthermore, some residues alteration of Cu-NiRs would contribute to the catalytic reaction. In this review, the latest progresses about the construction features, the process of electron transfer and catalytic mechanism of Cu-NiRs were discussed.

Aim To study the effect of Macrophage colony-stimulating factor(M-CSF) on MMP-9 in RAW 264.7 cell and explore the relationship between atherosclerosis caused by M-CSF and the activity of MMP-9. Methods Gelatin zymography analysis was used to investigate the effect of M-CSF and PD98059 on the activity of MMP-9 in cultured RAW 264.7 cell.Western blot was used to study the effect of M-CSF and PD98059 on the express of p-ERK1/2 in cultured RAW 264.7 cell. Results The enzyme activity of MMP-9 was significantly increased after 24-hour M-CSF treatment.Meanwhile, M-CSF upregulated the expression of p-ERK1/2. Pre-treatment with PD98059 blocked partly the increased expression of p-ERK1/2 and the activity of MMP-9 induced by M-CSF. Conclusion M-CSF can induce the secretion of MMP9 in RAW 264.7 cell, which may be mediated by the phosphorylation of ERK1/2.

Objective To assess the efficacy and safety of two different protocols of ketogenic diet (KD)-eating on demand or eating at regular intervals for refractory epilepsy in children.Methods Sixty children with refractory epilepsy were randomly divided into eating on demand group (n =30) and eating at regular intervals group (n =30) by random number table method.After taking the whole amount of KD,the capillary blood ketone and glucose level and urine ketone were monitored every 6 hours in 72 continuous hours.Seizure frequency and onset time were recorded.Antiepileptic efficacy and diet tolerability of the two groups were evaluated on 4 weeks,12 weeks,24 weeks and 48 weeks after initiating the diet.Adverse effects were monitored.Results After treatment of 4 weeks,the complete seizure remission rates of eating on demand group and eating at regular intervals group were 33.3％ (10/30) and 30.0％ (9/30) respectively,which suggested a comparable efficacy for two groups (P ＞ 0.05).The day when KD started to work was averaged (6.18 ± 2.42) d and (8.63 ± 2.63) d respectively.The group of eating on demand showed a faster onset of action (P ＜0.05).After treatment of 12 weeks,24 weeks and 48 weeks,complete seizure remission rates of eating on demand group were 30.0％ (9/30),34.8％ (8/23) and 36.8％ (7/19) respectively;the eating at regular intervals group were 33.3％ (10/30),30.4％ (7/23) and 44.4％ (8/18) respectively.The two groups had no significant difference (P ＞ 0.05).One year later,the treatment retention rates of the two groups were 63.3 ％ (19/30) and 60.0％ (18/30) respectively.There was no significant difference (P ＞ 0.05).The adverse effects mainly including transient gastrointestinal symptoms and metabolic disturbances were mostly tolerable and curable.Conclusion The two different protocols of KD-eating on demand and eating at regular intervals are both effective and well-tolerated for refractory epilepsy in children.While protocol of eating on demand is more easier to achieve ketotic state and the effect is more quickly,so it can be more easily received by children.Therefore in clinical practice,we can choose flexible eating time according to children's eating habits,which can improve the therapeutic compliance.

OBJECTIVE: To explore. HRCT and MRI three-dimensional fast imaging employing steady state ac-quisition(3D-FIESTA) imaging features and clinical characteristics of bilateral large vestibular aqueduct syndrome(LVAS). METHOD: The imaging and clinical features of 14 cases of bilateral LVAS identified over a 5-year periodwere retrospectively analyzed. All patients underwent HRCT and MRI 3D-FIESTA scanning of head and neck;MRI three dimensional reconstructions of internal acoustical meatus were also completed at the same time. RESULT: Audiogram showed mild to moderate hearing loss and was progressive. The cut-off values for the coronal midpointand operculum planes on the HRCT scan to diagnose an EVA were 1. 5 mm and 4. 3 mm respectively; the averagevalue was 2. 4 mm. VA expansion degree were not linked to the degree of hearing loss. MRI showed VA andlymph sac abnormalities. Concomitant image finding was cochlear hypoplasia. CONCLUSION HRCT and MRI 3D-FI-ESTA are important examinations for accurate diagnosis of LVAS. HRCT can acquire the specific size of reamedVA. MRI and 3D reconstructions of internal acoustical meatus can noninasive show more intuitive display ofLVAS and other inner ear malformations than HRCT.

Objective To evaluate the feasibility and safety of taking arbitrary position in the early period after laparoscopic cholecystectomy.Methods 186 patients who underwent laparoscopic cholecystectomy from Jun.2010 to Oct.2010 were randomly divided into two groups,observation group (n =94) and control group ( n =92) ; the former group was instructed to freely mobilize 2 hours after the operation,while the latter group was administered with traditional nursing.Abdominal distension,pain,urinary retention of both groups after laparoscopic cholecystectomy were compared.Results The observation group happen abdominal distension 4 cases,urinary retertion in 3,lumbar muscle ache 15 cases and control group happen abdominal distension 13 cases,urinary retention in 12 cases,lumbar mascle ache 60 cases,and muscle soreness after laparoscopic cholecystectomy were obviously lower in the observation group,and the differences between both groups were statistically significant ( x2 =5.460,6.087,46.885 ; P ＜ 0.05 ).Conclusions Taking arbitrary position in the early period 2 hours after laparoscopic cholecystectomy is safe and feasible,it can also reduce the occurrence of abdominal distension,urinary retention and muscle soreness,mitigate pain,dizzy,palpitation and lack of energy,and facilitate patients' early recovery.

To comparatively evaluate the efficacy and post-operative complications of the Madigan's prostatectomy (MPC) and suprapubic prostatectomy (SPPC). Methods: A total of 43 patients with benign prostatic hyperplasia were divided into two groups: 21 underwent MPC and 22, SPPC. In all the patients, the international prostate symptom score (IPSS) and urinary pressure-flow studies were assessed before and 6 months after operation. The International Continence Society (ICS) nomogram, Abrams-Griffiths (AG) number and linear passive urethral resistance relation analysis (L-PURR) were used to diagnose and grade bladder outlet obstruction (BOO). The IPSS and the urodynamic parameters before and after operation, as well as the advantages and post-operative complications were recorded and compared. Results: Patients of both the MPC and SPPC groups had a significant improvement in IPSS and urodynamic parameters. Obstruction was relieved in 81.0% of MPC and 86.4 % of SPPC patients. MPC has the advantages of the absence of postoperative hematuria and post-catheter stricture, a shorter period of hospitalization, and lower incidence of retrograde ejaculation and erectile dysfunction. Conclusion: Both MPC and SPPC can effectively relieve BOO. MPC has certain advantages and a lower incidence of complications as compared with SPPC.
