Objective: To describe the status of the basic public health service in township health centers, analyze the resource allocation which influences the supply of basic public health service. Methods: The data is based on monitoring project surveys collected by the health statistical information center, Spss13.0 and Excellare applied to make descriptive statistic analysis. Results:Overall, basic public health service has been carried out well in each area, but there are differences among the application rates of different basic public health service items; basic public health service can be effected by the level of basic public health input and the number of public health workers.

Objective To investigate the effect of eosinophils(EOS)in asthmatic guinea pigs airway and explore the mechanism of antiasthma by inhaled arsenic trioxide. Methods The guinea pigs asthma models were established with ovalbumin(OVA)challenge method,2 groups received inhaled different doses of arsenic trioxide,and three control groups respectively received normal saline inhaled and high dose of arsenic trioxide by intraperitoneal injection and dexamethasone(DEX)intraperitoneally. EOS invaded and apoptosis with all of the groups were assessed after 7 days intraperitoneal injection or inhalation. Results Compared with group of inhaled normal saline, both EOS invaded and apoptosis in bronchus submuconsa were significantly different(P0.05)among groups of inhaled low dose arsenic trioxide [2.0 mg(kg?d)]and intraperitoneal injection with higher dose arsenic trioxide[5.0 kg/(kg?d)]and DEX[10 mg/(kg?d)]for these two parameters. Conclusions The mechanism of arsenic trioxide antiasthma with arsenic trioxide can decrease EOS amount in bronchial submucosa and accelerate EOS apoptosis, and relieve bronchial inflammation in asthma. For inhaled lower dose arsenic trioxide or intraperitoneal injection with high dose arsenic trioxide ,the effect of EOS is equivalent. The antiasthma effect of inhaled lower dose arsenic trioxide[2.0 mg/(kg?d)]is equivalent to intraperitoneal injection higher dose[5.0 mg/(kg?d)],and may be safe comparatively. The mechanism of antiasthma by inhaled arsenic trioxide is the same with DEX.

Objective To evaluate the performance of an improved skin prick test in the screening for allergens.Methods A total of 475 patients with chronic urticaria who aged from 3 to 81 years were enrolled in this study,and classified into the control group (n =235) and research group (n =240).Traditional and improved skin prick test were conducted in the control and research group respectively.The allergen detection rate was compared between the two test methods.Results The allergen detection rate was 65.4％ and 67.2％ respectively for the improved and traditional skin prick test,respectively (P ＞ 0.05).House dust mites were the most common sensitizing agent.Conclusion The improved skin prick test can offer reliable evidence for chnical diagnosis with a relatively convenient and safe procedure.

OBJECTIVETo explore the effects of high altitude on cognitive flexibility.

METHODSSimulated hypoxia at an altitude of 3 600 m was performed in a hypobaric chamber. Twenty-three volunteers without hypoxic experience were selected and the mean age was about 25.1 years. The physiological parameters (heart rate, blood pressure and oxygen saturation) were measured. Task switch paradigm was used to explore the cognitive flexibility in each phase, and the changing anxiety state was evaluated simultaneously.

RESULTSReaction time (RT) switch cost in hypoxia phase showed a significant increase compared with the baseline; anxiety level in hypoxia phase was higher than the adaptation phase; a remarkable negative correlation between anxiety level and RT switch cost was found in adaptation phase, whereas a positive correlation was found in landing phase.

CONCLUSIONHigh altitude (3 600 m) affects cognitive flexibility and anxiety state. Anxiety before the hypoxia exposure improves the cognitive flexibility performance, while anxiety after the hypoxia exposure hampers the performance because of the post-hypoxia effect.

Objective To investigate the current situation and variation in the tendency of Kaschin-Beck disease (KBD) in Shanxi province, to assess the effectiveness of prevention measures, and to provide evidence for making scientific and effective tactics in prevention and control of the disease. Methods In 2008, according to "The National Technical Scheme for Kaschin-Beck Disease Control in 2007", children aged 7 - 12 years underwent clinical and X-ray examination in two historical severe KBD areas of Shanxi province, the observed position on Xray film was finger bone and carpal bone. Adults aged 16 years and above were clinically examined in 50 villages of 13 counties of KBD areas, Shanxi province. The diagnosis was based on "Diagnostic Standard of Kashin-Beck Disease"(GB 16003-1995), the adult patients were degreed according to the state of illness and divided into different groups according to their ages. Results A total of 181 children were examined, none of them was diagnosed as clinical KBD patient. The positive cases of X-ray were 2, X-ray detectable rate of metaphysis was 1.1% for children.In the 50 villages 13 871 of adults were examined and 801 KBD patients were found and the detectable rate was 5.77%. The detectable rate increased with age. The adult patients distributed mainly in the subpopulation aged 51years and above and these patients accounted for 70.66% (566/801) of total people examined. Degrees Ⅱ and Ⅲ patients at these ages accounted for 71.78%(206/287) of total degrees Ⅱ and Ⅲ patients. Conclusions The state of child KBD in Shanxi is under the national control standards. The detectable rate of adult KBD is higher. Relevant departments should pay close attention to the treatment of adult patients.

OBJECTIVETo analyze the results of postoperative radiotherapy with electronic beam for patients with keloids in our hospital.

METHODSFrom September 2006 to May 2009, radiotherapy was given within 24 hours after operation in 53 keloid patients. With single vertical field irradiation, 6-12 Mev electronic beams of Linear Accelerator were selected for different incision depth in different sites. The field size was 1.0 cm (range: 0.5-2.0 cm) away from both incision ends and 1.25 cm (range: 0.75-2.50 cm) away from incision laterally. The radiation was given daily with median treatment course of 4 days (range: 3-21 days) at 3.5 Gy/Fx to a median total dose of 14 Gy (range: 8-20 Gy). SPSS 21. 0 was used for analysis.

RESULTSAll postoperative incisions healed in one stage, the median follow-up was 34 months (range: 18-63 months). The overall local control rate was 79.7%. For patients who received the dose of more than 14 Gy versus less than 14 Gy, the local control rate was 81.6%, 75.2%, respectively (P > 0.05). For male and female, the 3 year local recurrence rate were 45.3%, 9.9% respectively (P = 0.008). Multivariate analysis showed that the sex (male versus female) was an independent prognostic factor (P = 0.036).

CONCLUSIONSurgery combined with electronic beam irradiation is a rather effective way to treat keloids. The local control rate would have a better trend if the total dose was higher than 14 Gy. Sex is an independent prognostic factor.
