There was a statistically significant post-treatment difference in plasma viscosity between the treatment and control groups (P<0.05). The total efficacy rate was 94.0% in the treatment group and 84.0% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Acupuncture at Huatuo jiaji points plus point Shixuan bloodletting is an effective way to treat cervical spondylotic radiculopathy.

Objective To evaluate the efficacy and safety of alteplase (rt-PA) thrombolytic therapy on patients with acute ischemic stroke aged over 80 years old.Methods The observational cohort study were conducted.One hundred and thirty-six patients with acute cerebral infarction and received rt-PA thrombolytic treatment were selected as our subjects with incidence time of 4.5 h,and the rt-PA dose of 0.9 mg/kg.The patients were divided into ≥80 years old group(n =34) and ＜80 years old group(n =102).U.S.A national institutes of health stroke scale (NIHSS) score of two groups evaluated before thrombolysis,immediately after thrombolysis 24 h,7 d and 14 d.The incidence and mortality rate of intracranial hemorrhage (ICH) and symptomatic intracranial hemorrhage (sICH) of two group were compared; and the score of modified Rankin's Scale (mRS) followed-up of 90 d were evaluated.Results NIHSS score after thrombolysis 24 h,7 d and 14 d of two groups were significantly lower than that before thrombolysis,and the differences were statistically significant (t =4.123,9.936,9.679,5.657,8.154,6.956,P ＜0.01).The score after thrombolysis 24 h,7 d and 14 d of two groups were no statistically significant difference.The efficient rate of treatment of two group were 55.88％ and 61.76％ respectively(P =0.54).Mter follow-up of 90 d,the prognosis rate were 47.06％ and 64.71％ respectively(P =0.07),and there were no statistically significant difference.Incidence rate of ICH were 11.76％ and 5.88％ respectively(P =0.07).Occurrence rates of sICH were 5.88％ and 2.94％ (P =0.43).Mortality rate were 11.76％ and 9.80％ (P =0.33),and there were no statistically significant difference.Conclusion This study shows that 80 years of age or older patients with acute ischemic cerebral apoplexy patients using rt-PA intravenous thrombolytic therapy is safe and effective,but RCT need further study.

Objective To explore the approaches to improve the detection of early gastric and precancerous lesions for basic level hospi-tals. Methods The 72 patients with abnormal gastric mucosa observed by gastroscope arranged with pathology after acetic acid-indigo car-mine dyeing were considered as the dyeing group, and 68 patients with abnormal gastric mucosa observed by gastroscope directly arranged with pathology were considered as the control group. The dyeing conditions of gastric mucosa were observed and compared to pathology detec-tion. The detection rate of early gastric cancer and precancerous lesions in the two groups were compared. Results After acetic acid-indigo carmine dyeing, there were 16. 7% of demonstrated discoloration, 63. 9% of poor dyeing, and 14. 3% of even dyeing. The detection rate of early gastric cancer and high grade intraepithelial neoplasia in patients with mucosa discoloration (91. 7%) was obviously higher than that in patients with poor dyeing (8. 6%) or even dyeing (0. 0%). The detection rate of low grade intraepithelial neoplasia or intestinal metaplasia in patients with poor dyeing (82. 6%) was obviously higher than that in patients with mucosa discoloration (8. 3%) or even dyeing (14. 3%). The detection rate of early gastric cancer and precancerous lesions in dyeing group (13. 9%,63. 9%) was obviously higher than that in control group (2. 9%,29. 4%). Conclusion The acid-indigo carmine dyeing could increase the diagnosis of early gastric cancer and precancerous lesions in basic level hospital. It is adaptable to extend approach in basic level hospital for its low cost and simple operation.

Objective: To explore the effects of different doses of Zn on the expression of metallo- thionein(MT) isoforms in hippocampus, olfactory bulb, diencephalon and cortex in stress rats. Method: The animal model of psychological stress was developed by restraint for 4w. Wistar rats were randomly assigned to 8 groups: control group, Zn-deficient group, pair-fed group, Zn -supplemented group and their corresponding stress groups. The expressions of MTs and their mRNAs were detected by Western blot and RT-PCR respectively. Results: In Zn-deficient group, plasma zinc content was decreased, while in Zn -supplemented group slightly increased. Compared with Zn-deficient group, the stress Zn -deficient group had higher expressions of MTs and MT-1 mRNA, MT-3 mRNA in hippocampus, olfactory bulb, diencephalon and cortex. Expressions of MTs in Zn-supplemented group were increased, and much more in corresponding stress group. In addition, the levels of plasma cortisol, IL-6 and IL-1 were increased clearly in Zn-deficient group and stress groups. Moreover, MTs’ productions were different in four brain domains,the highest in hippocampus and the lowest in diencephalon. Conclusion: Zn may affect the expressions of MTs and MT-1 mRNA, MT-3 mRNA in different regions of brain in stress rats. The higher production of MTs in hippocampus may be related to its role in body’s adaptation to stress. Cortisol, IL-6 and IL-1 may be involved in the modulation of expression of MTs.

Objective To observe the effects of psychological stress on the levels of Hcy and folate in rats. Method The Wistar rats were randomly assigned to three groups as follows:control,stress and stress with folate supplement. The animal model of psychological stress was developed by restraint. Results The levels of Hcy both in plasma and cerebrospinal fluid were increased and not only the level of folate in plasma but also in cortex,hippocampus,liver and mucous membrane epithelium of small intestine were decreased under restraint stress. Folate supplement could improve the depletion of folate and the increase of Hcy induced by restraint. Conclusion The depletion of folate may be one of the important factors of high Hcy level induced by psychological stress.
