Objective To explore the setting of logos on tobacco control information at outlets for retails and restaurants in 12 selected cities of China.Methods For all the shops for retail of tobacco,alcohol,food and restaurants under survey in 333 blocks of 12 cities (Beijing,Tianjin,Shanghai,Qingdao,Hangzhou,Shaoxing,Suzhou,Nantong,Zhenjiang,Chengdu,Xining and Harbin),setting and contents of logos on tobacco control information,inside and outside them were examined.Results 45 700 objectives were included in the study.Among all types of retail shops,the identification rate of tobacco control information at the entrance and inside were 3.6％ and 4.4％,with an overall identification rate as 7.0％.The overall rate at the entrance of all the restaurants was 4.6％ which was larger than the ones at the retail shops.Our result showed that there were differences between cities and types of establishments and higher rates seen in the larger ones.Of all the places that having had placement of information on tobacco control,only 18.5％ of them had put them both inside and outside.Slogans or images on "No Smoking" were the main forms of information but less than 10％ of them would show signs as ‘exclusive non-smoking'.Conclusion Data from our survey showed that the identification rate of tobacco control information was at a low level in 12 cities,and differences were seen between cities,size of establishment,that called for improvement of the existing tobacco control policies in China.

OBJECTIVETo investigate the effect of acupoint Shuigou (GV 26) and non-acupoint on inhibiting the neuronal necrosis induced by the middle cerebral artery obstruction (MCAO) in rats through the morphological observation.

METHODSForty two healthy adult male Wistar rats were randomly divided into a normal group, false-ope ration group, model control group, non-acupuncture group, Shuigou-acupuncture group and non-acupoint acupuncture group, 7 rats in each group. Besides the normal and false-operation groups, the experimental modal of MCAO was established in the other groups by using the Zea-Longa thread method. Acupoint Shuigou (GV 26) and non-acupoint (below the costal region) were selected respectively in the Shuigou-acupuncture group and non-acupoint acupuncture group for puncturing at 180 times/min for 5 seconds. Its effect was estimated by measuring the rate of the neuronal necrosis at the level of the light microscope and the degree of the neuronal necrosis at the level of the electron microscope.

RESULTS(1) At the level of the light microscope, comparing with the model control group (0.66 +/- 0.18), of the neuronal necrosis there were no significant differences in the rate of neuronal necrosis in the non-acupuncture group (0.67 +/- 0.34) and non-acupoint acupuncture group (0.59 +/- 0.11) (both P > 0.05), while it was significantly decreased in the Shuigou-acupuncture group (0.200 +/- 12) (P < 0.05). It indicates that no intervention and wrong (non-acupoint) intervention could light the damage of the neurons, however, only right intervention (Shuigou, GV 26) can obviously decrease the rate of the neuronal necrosis, showing with the specificity of acupoint. (2) At the level of the electron microscope, the ultrastructure of the involved neurons in the non-acupuncture group and non-acupoint acupuncture group is similar to that of the model control group, showing with the serious edema and structure damage. In contrast, the ultrastructure of the involved neurons in the Shuigou-acupuncture group is similar to that of the normal group and false-operation group, showing with light neuronal damage.

CONCLUSIONAcupuncturing Shuigou (GV 26) could protect the involved neurons and inhibit the neuronal necrosis induced by the MCAO in rats, but acupuncturing the non-acupoint couldn't, which imply that there is the specificity of acupoint in the acupuncture.

OBJECTIVETo probe into effective methods for treatment of ischemic cerebral infarction and specificity of acupoints in the acupuncture treatment.

METHODSThe rat model of middle cerebral artery occlusion (MCAO) was established with thread ligation according to Zea-Longa's method. They were divided into normal group, non-operation group, model control group, non-acupuncture group and acupuncture group, and the acupuncture group was divided into sham-acupuncture group and four Xingnao Kaiqiao groups (contain Shuigou group, Neiguan group, Chize group, Sanyinjiao group and Weizhong group). Then they were treated by acupuncture at "Shuigou" (GV 26), "Neiguan" (PC 6), "Chize" (LU 5), "Sanyinjiao" (SP 6), "Weizhong" (BL 40) and non-acupoints, 3 times/second, for 5 seconds. Cerebral blood blow (CBF) was used for assessment of the effect.

RESULTSAs compared with the model control group, in the non-acupuncture group CBF did not significantly change (P>0.05); compared with the non-acupuncture group, after acupuncture CBF was significantly increased in the Shuigou group and the Neiguan groups (all P<0.05), but did not significantly increased in the Chize group, Sanyinjiao group and Weizhong group (all P>0.05).

CONCLUSIONCBF has a tendency of spontaneous cure within 72 h after cerebral infarction in the MCAO rat; acupuncture can significantly improve CBF in the MCAO rat, so it is an effective method for treatment of ischemic stroke; among the acupoints in the "Xingnao Kaiqiao" needling method, "Shuigou" (GV 26) and "Neiguan" (PC 6) have obvious effect in improvement of CBF, indicating acupoint specificity of "Shuigou" (GV 26) and "Neiguan" (PC 6) in treatment of ischemic stroke.

Objective To study the epidemic tendency of emerging influenza A (H1N1) in mainland China, and to explore the different patterns of spread on the disease under the following contexts: (1) To stop the temperature screening program at the border areas of the country; (2)To stop measures of prevention and control on those identified cases and their close contacts; (3) To strengthen programs for the foreign immigrants on 'home quarantine'. Methods Under relevant parameters and information on the transmission link from different reference data, the patterns of influenza spread were simulated by Monte Carlo method. Results The temperature screening on border could inhibit the transmission of influenza A (H1N1) to some extent, so that after 3 months the cumulative number of cases will be reduced by 21.5% (1718 cases) and transmission speed of influenza A (H1N1) in mainland China will be delayed by about 4 days. Furthermore, taking positive measures of prevention and control could efficiently slow down the epidemic, so that after 3 months the cumulative number of cases will be reduced by 93.4%(about 90 thousand cases) and it would be delayed by about 15 days if influenza A (H1N1) spreads to the whole country. In addition, if the immigrants were able to practise quarantine measures consciously by themselves at home the effect of prevention and control against influenza A(H1N1) would be more significant. If 30%, 60% and 90% of immigrants would take quarantine measures home consciously, after 3 months the cumulative number of cases will be reduced by about 15% (about 940 cases), 34% (about 2230 cases) and 64% (about 4180 cases), respectively. Also, influenza A (H1N1) spreads to the whole country will be delayed by about 4 days, 10 days and 25 days, respectively. It is difficult to curb fully the development of the epidemic by taking existing control measures, and influenza A (H1N1) may spread to almost all provinces after about 3 months. Conclusion The effects of existing prevention and control measures were objectively assessed and the results showed the necessity and effectiveness of these measures against the transmission of influenza A (H1N1) , in the mainland of China.

OBJECTIVETo investigate the effects of minimally invasive esophagectomy (MIE) and open esophagectomy (OE) on the level of circulating tumor cells (CTCs) in patients with esophageal cancer (EC).

METHODSA total of 73 patients with EC undergoing MIE (n=38) or OE (n=35) in our department between October, 2015 and October, 2017 were enrolled, with 10 patients with benign esophagus disease and 10 healthy volunteers as controls. The levels of CTCs in the peripheral blood of the participants were detected using CanPatrol technique and analyzed for their association with the operation methods and perioperative complications.

RESULTSCTCs were detected in 60.3% (44/73) of the EC patients but in none of the control subjects. CTC level after the surgery was significantly higher than that during the surgery, and CTC level during the surgery was significantly higher than that before surgery (P<0.001). The preoperative and intra-operative CTC levels were not significantly different between MIE and OE groups (P>0.05), but the postoperative CTC level was significantly lower in MIE group than in OE group, and postoperative increment of CTC level (from the preoperative level) was significantly lower in MIE group than in OE group (P<0.001). The total incidence of postoperative complications was significantly lower in MIE group than in OE group (28.9% vs 54.3%, P=0.023), and in both groups, CTC levels in patients with complications were significantly higher than those in patients without complications (P=0.001 and P=0.005 in MIE and OE groups, respectively).

CONCLUSIONMIE may help to reduce the number of peripheral blood CTCs early after the operation, and dynamic monitoring CTCs level assists in evaluation of the prognosis of EC patients. CTC level may serve as an indicator for monitoring the prognosis of EC.

OBJECTIVETo evaluate the effect of elevated basal follicle-stimulating hormone (FSH) on both the quantity and quality of oocytes and embryos and the clinical outcomes of pregnancy in women under 35 years of age.

METHODSA retrospective analysis was conducted for inspecting 294 in vitro fertilization-embryo transfer (IVF-ET) cycles in women under 35 years of age. According to the basal FSH levels, the women were divided into groups A, B, and C with basal FSH of 10-14.99, 15-19.99 and ≥20 IU/L, respectively, to compare the average number of oocytes retrieved, morphologies of the oocytes and embryos, and clinical outcomes of pregnancy.

RESULTSGroup A showed greater average numbers of oocytes collected, total embryos and good-quality embryos with a lower gonadotrophin dose required to achieve follicular maturity than groups B and C. The 3 groups showed no significant differences in the percentage of metaphase II oocytes, optimal embryos-blastomere number, normal fertilization rate, cleavage rate, good-quality embryo rate, implantation rate, pregnancy rates, live birth rate or miscarriage rate, but the pregnancy rates and live birth rate tended to decrease in women with basal FSH ≥15 U/L.

CONCLUSIONIn women below 35 years of age, an elevated serum FSH (especially one ≥15 U/L) indicates diminished ovarian reserve and reduced numbers of oocyte and embryo but not poor oocyte or embryos quality, and good clinical pregnancy rate can still be expected.

Objective To describe the epidemical characteristics of A (H1N1) influenza identified in the early stage (from May 11 to June 22, 2009) of the epidemic, in mainland China. Methods Epidemical characteristics of 420 confirmed A (H1N1) influenza cases reported from May 11 to June 22, 2009 were analyzed descriptively, including the distribution of age, sex, source of infection, main symptoms and incubation period. Results A total of 77.8% early cases in mainland China were imported from other countries. Three countries including America, Canada and Australia were attributed to 90% of the imported cases. Most of the cases were from 6 months to 73 years old, with 94% of them under 50 years. Most of the symptoms would include fever (81%), cough (40%) and sore throat (35%). The mean incubation period of second-generation cases was 4.3 (4.2±1.5) days. Conclusion Imported cases dominated the total cases in the early stage of the epidemic had similar gender distribution of those from exporting countries. Fever, cough and sore throat were the three main symptoms manifested in influenza cases. 2.5±1.9(1-11)days was found in imported cases between the day of off-board and the onset of symptoms. The incubation period was 4.3±1.7 (1-8) days among the secondary cases.

OBJECTIVETo discuss the mechanisms of electroacupuncture at "Neiguan" (PC 6) on p38 MAPK signaling pathway in rats with cardiac hypertrophy.

METHODSForty SD rats were randomly divided into four groups: a normal group, a model group, a model plus p38 MAPK inhibitor group, a model plus electroacupuncture group, ten rats in each group. The model rats were established by subcutaneous injection 3 mg/(kg x d) of Isoprenaline Hydrochloride; model plus p38 MAPK inhibitor group were injected 0.3 mg/(kg x d) of specific inhibitor SB 203580; model plus electroacupuncture group was treated by electroacupuncture at "Neiguan"(PC 6) with continuous-wave, 2 Hz and 1 mA for 20 minutes, once a day for 14 days. There was no treatment in other two groups. The contents of TNF-alpha and IL-1beta in heart tissue were detected by radioimmunoassay and the p38 MAPK, p-p38 MAPK by western blot.

RESULTSCompared with normal group, the contents of TNF-alpha, IL-1beta, p38 MAPK, p-p38 MAPK were significantly increased in model group (all P < 0.01). The contents of TNFalpha, IL-1beta, p38 MAPK, p-p38 MAPK were significantly decreased in model plus p38 MAPK inhibitor group and model plus electroacupuncture group, compared with model group, all P < 0.05; compared with normal group, P < 0.05, P < 0.01; but no significant difference between model plus p38 MAPK inhibitor group and model plus electroacupuncture group (P > 0.05).

CONCLUSIONElectroacupuncture at "Neiguan" (PC 6) can prevent the phosphorylation of p38 MAPK of myocardial hypertrophy, and the mechanism maybe adjust p38 MAPK signaling pathway by inhibiting the expression of TNF-alpha and IL-1beta.
