Objective To observe the clinical efficacy of XIE’s Wen Du Qu Mai (Warming the Governor Vessel to expel smog) needling method plus heat-sensitive moxibustion in treating chronic simple rhinitis due to yang deficiency. Method Eighty patients with chronic simple rhinitis due to yang deficiency were randomized into a treatment group and a control group, 40 in each group. The treatment group was intervened by acupuncture plus heat-sensitive moxibustion, while the control group was by medication. The symptom and sign score was observed before and after 1-week treatment, and the clinical efficacy was compared. Result The total effective rate was 85.0%in the treatment group versus 55.0% in the control group, and the difference was statistically significant (P<0.05). The symptom and sign scores were changed significantly after treatment in both groups (P<0.01,P<0.05). After treatment, the symptom and sign score in the treatment group was significantly different from that in the control group (P<0.05). Conclusion XIE’s Wen Du Qu Mai needling method is effective in treating chronic simple rhinitis due to yang deficiency.

0.05) . The CREB-1 protein expression in cortex and hippocampus was significantly up-regulated while that in nucleus accumbens was significantly down-regulated in chronic morphine dependence and abstinence group (groupⅢandⅣ) as compared with control group. The CREB-1 protein expression in nucleus accumbens in groupⅣwas significantly lower than that in groupⅢ. Conclusion Acute morphine dependence and abstinence do not significantly affect CREB-1 protein expression in the brain. The changes in CREB-1 protein expression are different in different brain regions in chronic morphine dependence and abstinence rats.

Objective To investigate the changes in inhibitory guanine nucleotide binding protein Gi_2 in five brain regions of morphine addicted rats: ventral tegmental area, nucleus accumbens, prefrontal cortex, hippocampus and locus caeruleus. Methods 36 adult male SD rats were randomly divided into six groups (n=6): acute morphine dependent group, acute abstinence group, acute control group, chronic morphine dependent group, chronic abstinent group and chronic control group. Morphine dependent models were reproduced. Withdrawal syndrome was induced with naloxone 5mg/kg for 30min in rats of abstinence group. All rats were sacrificed by decapitation. Frozen sections of coronal plane of respective brain regions (ventral tegmental area, nucleus accumbens, prefrontal cortex, locus coeruleus, hippocampus) were prepared. The relative concentrations of Gi_2 protein were determined with immunohistochemical methods. Results Gi_2 proteins in acute morphine dependent group and acute abstinence group were significantly decreased compared with that of acute control group in nucleus accumbens (P

Objective To ascertain the optimum condition for extracting Rhizoma polygoni cuspidati and Radix angelicae sinensis with alcohol. Method With extract yield and the amount of polydatin as index,the primary factors of affecting the extraction were optimized. Result The optimum extraction condition was as follows:taking 60% alcohol as solvent,the meterials were refluxed and extracted two times with 10 and 8 times volume of alcohol for 1.5 h and 1.0 h,respectively. Conclusion The optimum extraction process provides an experimental basis for industrial production.

Objective To summarize the diagnosis and treatment of 33 cases of Leriche syndrome. Methods A retrospective review of the clinical data of 33 cases of Leriche syndrome was done. Results Claudication and impotence occurred in 79.9% and 70.4% of the cases. Color Doppler ultrasonography, especially combining with CTA or MRA, was helpful for the diagnosis. Aortic angiography or DSA was necessary for the determination of the clinical patterns and selecting the therapeutic methods. Surgical patterns selestion should be considering the patients' general status and conditions of the affected vessels. Surgical treatment was performed on 25 cases, including12 aortoiliac artery bypasses , 6 aortobifemoral artery bypasses , 4 axillo bifemoral artery bypasses, 2 embolectomies by Fogarty tube only and 1 aortal interposition with artificial vessel plus renal artery plasty. Aorta iliac artery bypasses get the best results with 1 year patency rate(100%) in all cases, and 5 year patency rate of 75.0%, which was significantly superior to those axillo bifemoral artery bypass grafts with 5 year patency rate of 37.5%. All the other 8 patients without operation died within 5 months. Conclusions Early diagnosis and comprehensive therapy should be adopted to improve the long term patency rates of grafts transplantation in Leriche syndrome.

Objective To investigate the changes in CREB_1 proteins in five brain regions of rats with morphine addiction and withdrawal with the technique of immunohistochemistry. Methods Thirty six adult male Sprague-Dawley rats were randomly divided into six groups (n=6 for each), i.e. acute morphine dependent group, acute abstinence group, acute control group, chronic morphine dependent group, chronic abstinence group and chronic control group. Animals in dependent groups and abstinence groups were administered with morphine by intraperitoneal injection till morphine dependent models were established. The rats in abstinence groups withdrawal syndromes were induced with naloxone 5mg/kg for 30min. The rats in control groups were injected with saline. All rats were sacrificed by decapitation. The coronal sections of discrete brain regions (hypothalamus, nucleus accumbens, prefrontal cortex, locus coeruleus, hippocampus) were obtained. The relative concentrations of CREB_1 protein were determined with immunohistochemistry. Results In acute morphine dependent and abstinence groups, CREB_1 protein decreased significantly compared with the acute control group in locus coeruleus (P0.05). Conclusion The morphine-induced CREB_1 protein changes may reflect differential G protein-cAMP-CREB signal transduction pathways in morphine dependent and abstinence rats.

Objective The molecular basis for opiate tolerance and dependence remains poorly understood despite extensive investigation in several preparations, including the hippocampus. Recent studies have implicated that the hippocampus played a central role in opiate tolerance, dependence and withdrawal. The current study is to explore the change in guanine nucleotide binding protein-inhabitant (Gi_2) protein in primary cultured hippocampal neurons with morphine treament. Methods The hippocampus was harvested from newborn Sprague-Dawley rats. Primary hippocampal neuronal cultures of 7 days in vitro were used and divided randomly into six groups (n=6), i.e. morphine treatment 4h group (M4), 8h group (M8), 16h group (M16), 24h group (M24), 48h group (M48) and control group (C). All morphine treatment groups were treated with morphine (10?mol/L). C group was treated with saline. The G protein levels were determined with immunofluorscence and laser scanning confocal microscope (LSCM) imaging techniques. Results Gi_2 protein levels in M16, M24 and M48 groups decreased significantly compared with that in C group (P0.05). Among M16, M24 and M48 groups, Gi_2 protein level was lowest in the M48 group. Conclusion The results indicated that Gi_2 protein levels decreased significantly in primary cultured hippocampal neurons with morphine treatment, which might be a potential molecular mechanism of opioid tolerance and dependence.

Objective: To observe the controlled hypotension effects of nicardipine in 2 different ways for spinal tumor operalion. Methods: Twenty-four adult patients, scheduled for selective spinal tumor operation, were randomly divided into 2 groups. In groupⅠ(n=12), the nicardipine was infused at a rate of 10 μg*kg-1*min-1 and the infusion continued until MAP was at the level of 7.33-8.66 kPa, and then the rate was decreased to 1 μg*kg-1*min-1. In Group Ⅱ(n=12), nicardipine was given 0.01-0.02 mg/kg as the load dose, then infused at 1-2 μg*kg-1*min-1. Results: During the period of controlled hypotension, cardiac index(CI) increased significantly, other hemodynamic variables were stable and no hypertension rebound occurred in both groups. Reaching time of target blood pressure in groupⅡ was shorter than that in groupⅠ（P＜0.05）. The dose required to obtain target blood pressure in group Ⅱwas less than that in group Ⅰ（P＜0.05）. BP recovery time from discontinuing nicardipine infusion to pre-hypotension level,bleeding volume and transfusion volume were similar between 2 groups（P＞0.05）.During mass bleeding,　serious arrhythmia and oliguria did not occur in any case. Conclusion: Controlled hypotension with nicardipine is rapid, stable and easily controlled without hypertension rebound. Nicardipine has considerable protective effects on heart and kidney during mass bleeding. The method of bolus injection followed with intravenous infusion is more suitable to clinical application.

Objective: To observe the inhibitory effect of scopolamine(Spm) and chlopromazine (Clo) on withdrawal syndromes in morphine dependent rats. Methods: The intensity of withdrawal syndromes on the model of morphine dependent rats was recorded after single or muiltiple subcutaneous administration(sc) of Spm and Clo at different doses. Results: Withdrawal syndromes were markedly decreased when single Spm 1 mg/kg and Clo 0.5 mg/kg combined with morphine were injected (P<0.05). Spm+Clo(sc) had much stronger effects on inhibiting withdrawal syndromes after intraperitoneal (ip) naloxone in morphine dependent rats (P<0.01). Conclusion: Spm can act on Ach-receptor and relieve morphine withdrawal syndromes. Clo may have a synergistic action with Spm via α2-receptor in the locus coeruleus of the rat brain stem.

Objective To investigate the relationship between glomerular filtration rate (GFR) and diabetic retinopathy (DR) and macular thickness in patients with type 2 diabetes mellitus (T2DM).Methods A total of 161 T2DM inpatients were enrolled in this study.There were 95 males (95 eyes) and 66 females (66 eyes),with an average age of (62.2±11.0) years.The average duration of diabetes was (14.8±7.9) years.The patients were grouped according to the degree of DR.Among them,91 patients were no DR,24 patients were mild non-proliferative DR (NPDR),24 patients were moderate NPDR,13 patients were severe NPDR and 9 eyes were proliferative DR (PDR).Severe NPDR and PDR were combine into severe DR group for statistical analysis.All patients underwent direct ophthalmoscope,fundus colorized photography,spectral domain optical coherence tomography (SD-OCT),fasting blood-glucose,glycated hemoglobin and renal function examinations.GFR was evaluated by 99 mTcDTPA.DR degree was evaluated by direct ophthalmoscope and fundus colorized photography.Central subfield (CSF),central macular volume and mean retinal thickness (MRT) were measure by SD-OCT.The correlation between GFR and DR staging and macular retinal thickness were analyzed by Spearman correlation analysis and Pearson correlation analysis.Logistic regression analysis was used to analyze the correlation between GFR and presence of DR.Results GFR was gradually decreased in patients with no DR,mild NPDR,moderate NPDR and severe DR (F=12.32,P＜0.001).Pearson correlation analysis demonstrated that GFR was negatively correlated to CSF (r=-0.202,P=0.010);but no correlation with MRT (r=-0.087,P=0.272).Spearman correlation analysis demonstrated that GFR was negatively correlated to DR staging (r=-0.325,P ＜ 0.001).The difference of DR prevalence rate in normal,slight abnormal renal function and renal insufficiency patients was significant (x2=12.32,P=0.002).Logistic regression analysis demonstrated that lower levels of GFR was significantly associated with presence of DR (95％ confidence interval=1.71-4.32,odds ratio=2.72,P＜0.001).Conclusion In T2DM patients,GFR is negatively correlated to DR staging and CSF.Lower GFR is independent risk factors for DR.
