Objective To analyze the epidemical distribution of intestinal nematode infections in Jiangsu Province in recent 30 years,so as to provide the evidence for improving prevention and control of intestinal nematodiasis in the future. Methods The literature related to intestinal nematode infections in Jiangsu Province from 1984 to 2012 was searched and the infection data in them were sorted and analyzed. Results A total of 26 papers were obtained. In the recent 30 years,the infection rates of Trich-uris trichiura,Ascaris lumbricoides and hookworm in Jiangsu Province decreased gradually,but the infection levels in northern Ji-angsu were higher than those in central and southern Jiangsu. In northern and central of Jiangsu Province,the descent speed of the intestinal nematode infection levels was faster before 2000,and then it slowed down after 2000. In southern Jiangsu,the descent speed of the infection level of A. lumbricoides was the fastest,but the infection level of T. trichiura with slight fluctuation kept rela-tively steady. From 1984 to 1989,the infection rates of the 3 intestinal nematodes above-mentioned in all age groups were high, and those of T. trichiura and A. lumbricoides were above 20%and 30%,respectively,and the infection rates of hookworm in mid-dle aged and elderly populations were relatively high. From 1990 to 2000,the infection rates of A. lumbricoides in children and teenager as well as that of hookworm in the people aged from 40 to 70 years were high,but those of T. trichiura and A. lumbricoides in the people above 70 years old were low. During the period of 2001 to 2012,the middle aged and elderly population and children were still the high-risk groups of hookworm and A. lumbricoides infections,respectively. Conclusions In the recent 30 years,the infection rates of intestinal nematodes in Jiangsu Province have decreased year by year,but the infection levels in northern Jiangsu are still higher than those in central and southern Jiangsu,which means that the northern Jiangsu is the key area of intestinal nema-todiasis control. Meanwhile,the A. lumbricoides infection rate of children and T. trichiura infection rate of the middle aged and el-derly population are high,which suggests that the control should put emphasis on the key population.

To cement the 5 years’ staged achievement of new medical reform so as finally achieve the objective of medical reform, public hospital would become the aim of reform in the following stage. On one hand , canceling “using drug to supple health care” in public hospitals has came into the crucial stage; on the other hand, the government needed to increase financial input and ensure the implementation of security fund. What was the relation between these two reforms? Therefore , based on the survey of county-level public hospitals in G Province, relationship among government compensation method, hospital public profit operation mechanism and profit-driven operation mechanism were analyzed; besides, different financial insurance mode had different operation efficiency. Because the construction of hospital expense under public profit operation mechanism was more reasonable , the required government insurance fund was less, which only accounted 32.9%of the required fund under the profit-driven operation mechanism. Therefore, the policy suggestions that government need to “buy the mechanism” and “be brave to implement ‘subtraction reform’” were proposed.

OBJECTIVE:To establish a rapid method for the concentration determination of lamotrigine (LTG) in human se-rum. METHODS:HPLC was adopted after serum samples treated with methanol. The column was Hypersil BDS C18(200 mm×4.6 mm,5μm)with the mobile phase of methanol-KH2PO4(45∶55,V/V)at the flow rate of 1 ml/min,the detection wavelength was 250 nm,and the temperature was 35℃. RESULTS:The linear range of LTG was 0.5-30.0 μg/ml(r=0.999 9). The RSDs of intra-day and inter-day were all less than 5% and the recovery was 101.96%-102.74%. CONCLUSIONS:The method is simple,accurate and fast,and suitable for the monitoring of LTG serum concentration.

Objective To compare the characteristics in initial sandplay of college students with high and low gregarious personality,to validate the psychological assessment function of the initial sandplay.Methods Used the 16-PF as the tool to selected the 56 students as the high gregarious group,and 36 students as the low gregarious group.Results On selection of toys,the proportions of high gregarious group were significantly higher than those in low gregarious group in total numbers,plants and daily necessities ((27.77 ± 11.01)vs (20.94 ± 8.76),(7.30 ±6.43)vs(3.25 ±2.85),(3.66 ±2.86)vs(2.25 ±2.57)),and significantly lower in religion toys (0.30 ± 0.47) vs (0.86 ± 1.09).On operation process,the proportion of starting with toys in high gregarious group was significantly higher than that in low gregarious group (94.6％ vs 25％).Their attitudes towards sand were random touch(28.6％ vs 5.6％) and indifference(62.5％ vs 41.7％).They used more grass(55.4％ vs 27.8％),more real characters(83.9％ vs 50％),fewer virtual characters(55.4％ vs 83.3％) and more dynamic changes in creation(14.3％ vs 0％),more applied by the social scene (39.3％ vs 0％).On the theme of sandplay,the high gregarious group was fewer appear by the empty,neglect,injury ((3.6％ vs 19.4％),(0％ vs 8.3％),(0％ vs 8.3％) respectively,P ＜ 0.05).Conclusion The results show that the high and low gregarious personality have significantly characteristics in initial sandplay.Sandplay is valuable to be a personality assessment tool.

Objective:To observe the clinical efficacy and adverse reactions of paroxetine combined with olanzapine in the treat-ment of depression complicated with sleep disorders. Methods: Totally 150 cases of sleep disorder patients were selected, and then randomly divided into the control group and the observation group with 75 ones in each. The control group was given paroxetine treat-ment, the observation group was given paroxetine combined with olanzapine treatment, and the treatment course was four weeks. The sleep latency, total sleep time, wake-up time and the number of awakening in the two groups were recorded, and the HAMD scale score and treatment efficacy were compared. Results:Compared with those in the control group, the sleep latency, total sleep time, wake-up time and the number of awakening in the observation group were obviously improved (P<0. 05). The clinical cure rate, the HAMD scale score and the incidence of adverse reactions between the two groups all had significant differences (P<0. 05). Conclu-sion:Paroxetine combined with olanzapine in the treatment of depression with sleep disorders shows fast efficacy, which can improve the sleep disorder symptoms and reduce the incidence of adverse reactions significantly.
