Objective To observe the effect of Niaoduqing granules on chronic renal failure in patients with blood lipid and blood homocysteine.Methods Patients with chronic renal failure were divided into observation group and control group by number table method,two groups of patients were both given low salt,low fat and high quality low protein diet,controlling blood pressure and blood sugar,correcting anemia,correcting calcium and phosphorus meta-bolic disorders,correcting of acidosis,while patients with combined infection were given positive anti infection treat-ment.Observation group was treated with Niaoduqing granules on that basis.The changes of triglyceride(TG),total cholesterol( HDL-C) ,total cholesterol( CHO) ,low-density lipoprotein( LDL-C) ,and plasma homocysteine( Hcy) were observed before and after treatment in the two groups.Results After treatment,CHO,TG,HDL-C,LDL-C, Hcy in the control group were respectively (4.83 ±0.22)mmol/L,(2.21 ±0.30)mmol/L,(0.69 ±0.11)mmol/L, (4.30 ±0.32)mmol/L,(24.35 ±7.05)μmol/L,that threre was no significant changes before and after treatment.In the observation group,TG,LDL-C,Hcy were (1.38 ±0.18)mmol/L,(3.29 ±0.13)mmol/L,(14.54 ±3.56)umol/L respectively after treatment,and which were significantly lower than that before treatment ( t=1.45,2.13,4.28,all P<0.05).HDL-C (1.42 ±0.31)mmol/L,were significantly increased after treatment as compared with that before treatment (t=3.88,P<0.05).The difference of Hcy,TG,LDL-C,HDL-C and CHO after treatment was statisti-cally significantin between the two groups (t=1.34,2.08,1.10,3.88,all P<0.05).Conclusion Niaoduqing gran-ules can improve lipid metabolism disorders in patients with chronic renal failure,and can reduce the serum homocys-teine.

Objective To investigate the role of microglial activation in spinal cord in a rat model of persistent postoperative pain evoked by skin/muscle incision and retraction (SMIR) .Methods Seventy-two male SD rats weighing 200-250 g in which intrathecal (IT) catheter was successfully inserted were randomly divided into 3 groups ( n = 24 each) : group sham operation; group SMIR and group SMIR + FT minocycline (a specific microglia inhibitor) . The rat model of persistent postoperative pain evoked by SMIR was established according to the method described by Flatters. Pain behavior was assessed by paw mechanical withdrawal threshold ( MWT) to von Frey filament stimulation at 1 day before (T0,baseline) and 3, 7, 12, 22 and 32 days after operation (T1-5,) . Four animals were sacrificed at each time point in each group for detection of the expression of Iba-1 (a specific marker of microglia) in the spinal dorsal horn by immunofluorescence and the microglia was counted. Results MWT was significantly decreasedat T1-4, while the expression of Iba-1 and microglia counts in the spinal dorsal horn were significantly increased at T1, 2 by SMIR in group Ⅱ. IT minocycline significantly attenuated the hyperalgesia induced by SMIR at T1-4 and decreased Iba-1 expression and microglia counts at T1,2 in group Ⅲ. Conclusion Microglial activation in the spinal cord plays an important role in the development and maintenance of SMIR-evoked persistent postoperative pain in rats.

Objective To investigate whether endogenous retinal stem cells can be activated in the retina of Royal College of Surgeons (RCS) rats during the onset and development of retinitis pigmentosa. Methods The RCS-p+ rats with inherited retinal dystrophy were divided into 3 groups: the initial stage group (15-day RCS rats), the mid-stage group (30-day RCS rats) and the advanced stage group (90-day RCS rats) according to the severity of degeneration (n=4 in each group). RCS-rdy+p+ rats without retinal degeneration served as controls, and divide into three groups (15-day control, 30-day control, 90-day control) matched with RCS-p+ rats. A transcription factor (Chx10) expressed by embryonic retinal progenitors was detected using immunofluorescence and Western blotting. Results All of the retinal layers in the three control groups and in the 15-day RCS rats did not express Chx10, while the positive expression was observed in the photoreceptor layers of the 30-day and 90-day RCS rats. Chx10 protein could be detected by Western blotting in all RCS groups, but expressed higher in 30-day RCS rats than in 15-day and 90-day RCS rats (P

Objective To explore the characteristics of DNA antigen deposited in the skin lesions of patients with lupus erythematosus (LE). Methods Thirty-two LE skin specimens were collected. The deposited immune complexes were obtained by cryoprecipitation methods. Then the samples were digested by protease. Finally DNA was extracted with phenol and chloroform. The size of DNA fragments was detected on agarose gel electrophoresis. Ten kinds of probes were used to analyze the origin of these DNA molecules by dot hybridization. Results DNA fragments were successfully isolated from 27 skin specimens with four kinds of different sizes including band-I (20 000 bp), band-Ⅱ (1 300 bp), band-Ⅲ (800-900 bp) and band-Ⅳ (100-120 bp). In 15 specimens most of DNA was identified as band-I. In 2 specimens band-Ⅰ, -Ⅱ and -Ⅲ were all noticed, while all four bands were detected in 10 specimens. There was a positive correlation between small-sized fragments (100-200 bp) and disease activity (P

We performed a meta-analysis of randomized controlled trials (RCTs) to investigate the efficacy and safety of ticagrelor (TIC) vs.clopidogrel (CLO) in patients undergoing percutaneous coronary intervention (PCI).In Jun 2016,a literature search was started and all the studies were conducted from 2010 to 2015.We systematically searched the literature through the MEDLINE database,Cochrane library,and EMBASE database.Quality assessments were evaluated with Jadad quality scale.Data were extracted considering the characteristics of efficacy and safety designs.Six RCTs enrolling 26 244 participants and satisfying the inclusion criteria were finally analyzed.There was a significant decrease of all-cause mortality (MD=0.83,95％CI=0.74-0.93,P=0.001) and myocardial infarction (MI) (MD=0.78,95％CI=0.70~.88,P=0.000).There were no significant differences in stroke (MD=1.34,95％CI=0.99-1.79,P=0.06),total bleeding (MD=0.97,95％CI=0.84-1.12,P=0.66),minor or major bleeding (MD=l.06,95％CI=0.94-1.19,P=0.35) in patients undergoing PCI after treatment with TIC vs.CLO.TIC could be more significant in decreasing all-cause mortality and MI than CLO,but there were no significant differences between TIC and CLO in inhibiting stroke,major bleeding,major or minor bleeding in patients undergoing PCI.

Therapeutic approaches to brain metastases from non-small cell lung cancer ( NSCLC ) include corticosteroids, anticonvulsants, surgery, radiotherapy and chemotherapy. In recent years, molecular targeted therapy such as the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) has become a new option. This article discussed the roles of surgery, brain radiation, chemotherapy, targeted therapy , and other new directions in the treatment of patients with brain metastases from NSCLC.

Objective To systematically review the efficacy of hydromorphone hydrochloride injection for treatment of chronic pain.Methods Web of Science Proceedings and PubMed were searched for clinical trials involving the efficacy of hydromorphone for treatment of chronic pain, with no language or time limit.Evaluation indexes included visual analogue scale (VAS) score and the rate of pain control or relief.The studies were screened independently, and the data were extracted by two researchers.Meta-analysis was conducted using the Stata 10 software.Results Eleven studies involving 452 patients were included in our meta-analysis.VAS score was significantly decreased after treatment compared with that before treatment.For the patients with cancer pain, VAS score was significantly decreased after treatment with hydromorphone hydrochoride injection, and the rate of pain control or relief was increased when compared with the other opioid analgesics.Conclusion Hydromorphone hydrochloride injection can treat chronic pain, and it may provide better therapeutic effect than the other opioid analgesics for the patients with cancer pain.

Objective To investigate the effect of medial preoptic area ( mPOA) destruction on the anesthesia induced with propofol and ketamine and the role of mPOA in the mechanism of anesthesia. Methods Twenty-four SD rats weighing 250-300 g were randomly divided into two groups: NS group ( n = 12) and NMDA destruction group ( n = 12) . The animals were anesthetized with intraperitoneal (ip) pentobarbital 40 mg?kg-1. A hole was drilled in the skull fixed by a stereotactic apparatus (Narishige). 0.5?l of normal saline (NS) or N-methyl-D-aspartate (NMDA) was injected into mPOA. The rats were observed for changes in behaviour and body weight. On the 7 th day after NS or NMDA injection each group was further divided into 2 subgroups receiving either propofol 100 mg?kg-1 or ketamine 100 mg?kg-1 ip. The latency of loss of righting reflex (RL)(time from end of ip injection to loss of righting reflex) and recovery time (RT) were recorded. Results There were no significant changes in behaviour and body weight after mPOA injection in NS group; while animals in NMDA-destruction group showed increased excitability , irritability and activity and decreased appetite and sleep and significant weight loss after mPOA injection. RL was significantly longer and RT was significantly shorter after propofol/ketamine ip injection in NMDA destruction group than those in NS group. Conclusion mPOA is probably involved in anesthesia induced with propofol and ketamine.
