Objective To understand the current state of staff for Plasmodium microscopy examinations in Changzhou City in the early stage of eliminating malaria action,so as to provide the evidence for achieving the target of malaria elimination. Methods The staff for Plasmodium microscopy examinations from medical institutions and centers for disease control and prevention at differ-ent levels were investigated by questionnaires and tests of the malaria related theory and microscopic operation. Results Totally 95 people were investigated,and among them,40.0%had college degree and 45.3%were university educated. There were 18.9%of them working on Plasmodium microscopy examinations for less than 1 year,40.0%for 2-5 years,18.9%for 6-10 years and 22.1%for more than 10 years. The numbers of person-time of provincial and municipal level training,district-level training,and unit-level training in the last year were 0.57,0.59,and 0.14,respectively. Totally 18.9%of them had the experience of finding Plasmodium at work,and 97.9% of them considered it was necessary or very necessary to do Plasmodium microscopy examina-tions. However,57.9%and 8.4%of them considered Plasmodium microscopy examinations increased their work load and work dif-ficulty,respectively. The average correct rates of knowledge tests on malaria before and after training were 72.5%and 91.6%re-spectively(P<0.05). The average mark of Plasmodium microscopic tests was 25.3 points(full mark being 50 points),and the passing rate(≥30 points)was 58.9%. Conclusion The working experience of staff for Plasmodium microscopy examinations in Changzhou City is relatively poor,and the related training should be enhanced.

Objective To analyze the Oncomelania hupensis snail distribution and the changes of snail situation in Chang-zhou City from 2013 to 2016,so as to provide the evidence for formulating the schistosomiasis prevention and control interven-tions. Methods The data of snail monitoring in Changzhou City from 2013 to 2016 were collected and statistically analyzed. Re-sults The total area with snails was 40.17 hm2 and the newly discovered area was 30.63 hm2 in Changzhou City from 2013 to 2016. In the four years,3454 snails were dissected,and no schistosome infected snails were found. There were totally 51 spots with snails,and the areas with snails of different types of marshland,inland and mountain were 12.13(30.19%),25.54 hm2 (63.57%)and 2.51 hm2(6.24%),respectively. In the newly discovered snail environment,the areas of types of marshland and inland were 8.00 hm2(26.12%)and 22.63 hm2(73.88%),respectively. The main causes for snail existence were external input and adjacent diffusion. In the past four years,the total snail control area with molluscicides was 71.74 hm2,the consolidated snail control area with molluscicides was 155.15 hm2,and the total environmental modification areas in the current snail spots and historic snail spots were 15.90 hm2 and 11.30 hm2 respectively. Conclusion The diffusion of snails in inland rivers is the key of the newly discovered snail areas in Changzhou City in recent years,and the snail monitoring and control measures should be strengthened in the future.

Objective To understand the status of knowledge,attitude,and practice of schistosomiasis prevention and con-trol and infection status in Armed Police Forces stationed along the Yangtze River,so as to provide the reference for formulating the schistosomiasis prevention and control measures in Armed Police Forces. Methods A questionnaire survey was conducted in the Armed Police Forces along the Yangtze River in Jiangsu Province,and the investigation content included social demo-graphic data,schistosomiasis prevention knowledge,attitude and behavior. All the subjects were examined for Schistosoma ja-ponicum infection. Results Totally 376 soldiers were investigated in 2 sites. The total passing rate of schistosomiasis knowl-edge was 72.87%. The passing rate among different age groups had no significant difference( χ2 =0.26,P > 0.05). The passing rate of soldiers from endemic areas was significantly higher than that of the soldiers from non-endemic areas( χ2 =4.71,P <0.05). The passing rate of officers was significantly higher than that of the soldiers(χ2 = 4.21,P <0.05). The passing rate of sol-diers with the education levels of junior school,high school,college,undergraduate and above increased gradually,with a sig-nificant difference( χ2 =8.16,P < 0.05). The soldiers with positive attitude accounted for 93.88%. Among the water contact be-haviors,training accounted for 17.55% and participating in the task(such as flood fighting and water work)accounted for 86.44%. When launching,the rate of taking protective measures was 52.93%. The rate of taking protective measures in the knowledge passing group was much higher than that in the knowledge failed group( χ2 =10.55,P < 0.05). The stool was harm-lessly treated in the two camps. Among 376 soldiers,the positive rate of blood examinations was 0.53%,but the stool examina-tions were all negative. Conclusions The overall level of knowledge and correct behavior of schistosomiasis prevention in the Armed Police Forces along the Yangtze River still should be improved. The better health education and behavior intervention are crucial to schistosomiasis prevention in the army.

Objective To summarize the therapeutic experience of lower limb pain syndrome caused by tacrolimus (FK506) after liver transplantation. Methods A 52-year-old male patient diagnosed with virus B hepatitis (hepatitis B), post-hepatitis liver cirrhosis at the decompensation stage and malignant liver tumors developed bilateral lower limbs pain syndrome after liver transplantation with FK506 immunosuppressant. After eliminating the possibility of angioneurotic pain, FK506 was terminated and replaced by sirolimus (SRL) therapy. The blood concentration was maintained at 6~8 ng/mLduring the early stage, and then gradually adjusted according to the survival time of the liver graft. Results After 2-weeks conversion therapy, the swelling and pain of bilateral lower limbs of the patient were gradually relieved, and the skin pruritus was gradually healed. After 1 month, the patient was basically restored to normal activity and function. No recurrence was reported until the submission date of this manuscript. Conclusions Bilateral lower limbs pain syndrome caused by adverse reaction of FK506 is relatively rare. FK506 can be substituted by SRL to avoid the adverse reaction.

Objective To analyze the correlation of tumor recurrence after liver transplantation for hepatocellular carcinoma (HCC)with the expression levels of regulatory T cell (Treg)and cytokines in peripheral blood. Methods A total of 56 patients who underwent liver transplantation in the 309th Hospital of People's Liberation Army from 2010 to 2014 were studied. According to the postoperative pathological data,all the patients were divided into the group of liver transplantation for HCC (HCC group,n=28)and group of liver transplantation for cirrhosis (liver cirrhosis group,n=28), of which the HCC group was further divided into non-recurrence group (n=8)and recurrence group (n=20)according to the situation of postoperative tumor recurrence. The expression levels of Treg and cytokines [vascular endothelial growth factor (VEGF),interleukin (IL)-2,IL-10,IL-12,transformation growth factor (TGF)-βand interferon (IFN)-γ]in peripheral blood of the patients in various groups were compared. Results Compared with the liver cirrhosis group,levels of IFN-γand IL-12 in the non-recurrence group increased significantly (both P<0.05);levels of Treg%,VEGF,IFN-γ, IL-10 and TGF-βin the recurrence group increased significantly,while levels of IL-2 and IL-12 decreased significantly (all P<0.05). Compared with the non-recurrence group,levels of Treg%,VEGF,IL-10 and TGF-βin the recurrence group increased significantly,while levels of IFN-γ,IL-2 and IL-12 decreased significantly (all P<0.05 ). Conclusions Levels of Treg and cytokines can be used to predict the tumor recurrence after liver transplantation for HCC.
