Shenghua decoction made by FU Qing-zhu is a famous formula aimed at syndrome of coagulation cold due to blood deficiency,static blood obstruction.The mechanism of disease is definite when this formula is applied.But the extensive use of Shenghua decoction,especially some potent preparation of it following childbirth without according to TCM principle based on differentiation of syndromes is a manifestation of highlighting formula and underestimating theory,which is useless and harmful.It should be emphasized.So the Shenghua decoction should be used under the direction of basic theory of TCM,through precise syndrome differentiation,according to the principle of "looking to and not being besieged by postpartum ".We should not follow blindly the method of treatment of "warming and resolving stasis" on the postpartum disease.It is important that Shenghua decoction should be used on the basis of syndrome differentiation.

To study whether the late-acting co-stimulatory molecules ICOS can suppress the apoptosis and sustain the survival and proliferation of T cells through the survivin pathway, ICOS signals deficient T-cells were infected with adenovirus carried survivin gene, other T-cells were given ICOS co-stimulatory signals, then infected with adenovirus carried dominant-negative mutant survivin gene. Apoptosis and proliferation were determined by TUNEL and CCK-8 respectively. The results show that engagement of ICOS signal increased the expression level of survivin significantly. Survivin can sustain co-stimulatory deficient T cells survival and suppress the apoptosis. Mutant survivin inhibits ICOS signal positive T cells survival and increase its apoptosis. Late-acting co-stimulatory molecules ICOS can suppress the apoptosis and sustain the survival of T cells through the survivin pathway.

Objective: To investigate the smoking cessation intention and attempt to quit smoking among smokers at ages of 15 years and older in a district of Beijing Municipality, so as to provide insights into formulation of tobacco control interventions. Methods: Permanent residents at ages of 15 years and older were sampled using a multi-stage stratified cluster sampling method from a district in Beijing Municipality, and all smokers were recruited. Participants' demographic features, tobacco use, intention to quit smoking, attempts to quit smoking and awareness of tobacco-related hazards were collected using the Beijing Adult Tobacco Survey. The intention and attempts to quit smoking were analyzed among smokers, and factors affecting the attempt to quit smoking were identified using a multivariable logistic regression model. Results: A total of 687 smokers were surveyed, including 669 men (97.38%), 497 from rural areas (72.34%), 351 daily smokers (51.09%), 336 occasional smokers (48.91%), 329 with intention to quit smoking (47.89%), and 178 with attempts to quit smoking during the past one year (25.91%). Univariable analysis showed that area, age, educational level, smoking status, tobacco health literacy and tobacco control information acquired from media were factors affecting intention and attempts to quit smoking among smokers (P<0.05). Multivariable logistic regression analysis showed that smokers with intention to quit smoking (OR=5.444, 95%CI: 3.585-8.268) and occasional smoking (OR=2.142, 95%CI: 1.312-3.497) were more likely to attempt to quit smoking. Conclusions Approximately half of smokers have intention to quit smoking in a district of Beijing Municipality; however, the percentage of attempts to quit smoking is low. Targeted interventions are required for smokers with different characteristics to improve the intention to quit smoking and promote smoking-quitting behaviors.

Objective To observe the changes of serum superoxide dismutase (SOD) levels in typeⅡdiabetic patients with peripheral arterial disease (PAD) before and after interventional therapy, and to investigate the effects of oxidative stress level and interventional treatment on serum SOD level. Methods During the period from July 2011 to December 2012 at authors’ hospital, a total of 40 patients with type Ⅱ angiography together with balloon dilation and/or stenting was carried out in 24 patients (group B, with Fontaine stage of Ⅱb - Ⅲ). Of the 24 patients in group B, lower limb arterial angiography together with balloon dilation was employed in 16 (group B1) and lower limb arterial angiography together with balloon dilation and stenting was adopted in 8 (group B2). Twenty healthy clinical subjects were used as control group (group C). Before interventional treatment, elbow venous blood samples of patients in group A and B were collected to determine serum lipid, HbA1c and SOD levels. The same tests were also carried out in the subjects of group C. During percutaneous lower extremity arterial intervention , through arterial sheath 3 ml arterial blood specimen was collected in all patients of both group A and B before intervention started. Twenty-four hours after the treatment, venous blood specimen was also collected in all patients to determine serum SOD levels. The results were statistically analyzed. Results Lower limb arterial angiography showed that no obvious arterial stenosis was seen in the patients of group A. The interventional procedures were all successfully completed in all patients of group B. SOD levels of group A, B and C were (46.1 ± 3.13)U/ml, (35.37 ± 3.58)U/ml and (60.50 ± 6.99)U/ml respectively. SOD levels of both group A and B were significantly lower than that of group C (t = 8.420, P < 0.01; t = 14.324, P < 0.01). The level of SOD in group A was significantly higher than that in group B (t = 10.092, P < 0.01). The ankle-brachium indexes (ABI) of group A, B and C were (0.70 ± 0.12), (0.58 ± 0.13) and (1.15 ± 0.07) respectively. ABI of group A and B was significantly lower than that of group C (t = 14.324, P < 0.01; t = 17.392, P < 0.01). ABI of group B was significantly lower than that of group A (t=3.027, P<0.05). SOD level bore a negative correlation with HbA1c level (r=-0.541, P<0.01). In both group A and group B, no significant difference in SOD level existed between the venous blood and arterial blood. The preoperative arterial SOD levels in group B1 and group B2 were (35.70 ± 3.04)U/ml, and (36.07 ± 2.14)U/ml respectively, and the difference between the two groups was not statistically significant. The preoperative SOD levels in the ischemic arterial region in group B1 and group B2 were (32.95 ± 3.52)U/ml and (33.59 ± 2.64)U/ml respectively, and the difference between the two groups was not statistically significant although these levels were significantly lower than the preoperative arterial SOD levels(t=2.741, P<0.05; t=2.704, P<0.05). After the interventional treatment, the SOD levels in the ischemic arterial region in group B1 and group B2 were (29.40 ± 5.49)U/ml and (26.68 ± 2.31)U/ml respectively, and the difference between the two groups was not statistically significant although these levels were significantly lower than the preoperative SOD levels in the ischemic arterial region (t = 2.536, P < 0.05; t = 5.005, P < 0.01). No statistically significant differences in SOD levels at each corresponding site existed between group B1 and group B2. Conclusion No significant difference in SOD level exists between the venous blood and the arterial blood. Serum SOD level carries a negative linear correlation with HbA1c level. Before interventional treatment , the SOD level in ischemic region is low, which becomes lower after the interventional procedure, which may be caused by the enhanced oxidative stress reaction that is resulted from the damage of the vascular wall due to interventional manipulations. The enhanced oxidative stress reaction may play an important role in the occurrence of restenosis.
