Objective To understand the current status of Oncomelania hupensis snails and the change rules,so as to pro?vide the evidence for formulating the snail control strategy. Methods The data of snails were collected and the factors influenc?ing the changes of snail status were investigated,and all the data were analyzed in Hailing District from 2007 to 2014. Results There were 18 environments with snails in 17 villages of 3 townships in Hailing District from 2007 to 2014. The snail area was 7.832 4 hm2. Among these environments and snail areas, 6 environments and 2.134 5 hm2, snail area were detected by the village snail investigation groups, and 12 environments and 5.697 9 hm2 snail area were detected by the township snail investigation groups. In addition, in 5 non?endemic villages, 3.126 3 hm2 snail area was found. In 2008, 2012 and 2013, a total of 2.274 0 hm2 snail area was found again. Conclusions In recent years,the snail situation rises again after schistosomiasis transmission has been interrupted. Therefore,this situation should be paid attention to.

Objective To investigate the epidemiological characteristics of imported malaria in Hailing District ,Taizhou City,so as to provide the evidence for formulating the effective prevention and control strategy. Methods The network reports, questionnaires and epidemic reports of imported malaria cases in Hailing District from 2010 to 2015 were collected and analyzed retrospectively. Results From 2010 to 2015,totally 46 cases of imported malaria were reported,including 40 cases of falci?parum malaria(86.96%),4 cases of ovale malaria(8.70%),1 case of quartan malaria(2.17%)and 1 case of multi?infection of falciparum malaria and tertian malaria(2.17%). No seasonal trend of time of the disease onset was observed. All the patients were return abroad with clear residence histories in malaria epidemic areas. The average time from disease onset to definite diag?nosis was 2 d and 8 patients were definitely diagnosed within 24 h. All the 46 patients were cured. Conclusion All the malaria cases reported were imported cases in Hailing District in the last five years. Effective prevention and control measures are the key to the malaria elimination.

High-consuming group is a special group which has good economic base, differmental culture and relgional belif customs. These patients alwanys need high quality medical service. How to integrate with these characteristics and make the nursing model of making patients' belife, moral ideas respcted, and rights proteded is a difficult problem. The author put forward we should rule nurse staff' s ethics and actions, provide a medical envionment from which can meet high-consuming patients physical and mental needs.

Immunohistochemistry examination showed that SOX-2 was expressed in all 23 cases of odontogenic cyst and in 2 cases of poly-cystic ameloblastoma.

Bilateral vasovasostomy was performed on 14 male rabbits which received a vasectomy 12 months ago. After 3 months, the rabbits were mated with female rabbits in a course of two months in order to observe the restoration of fertility. They were divided into vasovasostomy fertility group(VFG)and vasovasostomy infertility group(VIG), 7 rabbits, each according to their fertility. 8 rabbits that received a vasectomy only were designated as vasectomy group(VG), and 9 as sham-operation group(SOG), both (VG & SG) served as control. The results showed, (1)the value of sperm density in VFG was significantly lower than that in SOG, but markedly higher than that in VIG(P

Objective To explore the effect of Wendan Decoction plus Saffron in the treatment of patients with endometriosis of uterus on serum matrix metalloproteninases-9(MMP-9).Methods 74 cases of endometriosis of uterus were selected and randomly divided into two groups, 37 cases in each group.The control group were treated with oral administration of Gestrinone Capsules, the research group were treated on the basis of the control group with Wendan Decoction plus Saffron treatment,two groups were treated for 24 weeks.The serum estradiol, MMP-9 and matrix metalloproteninases inhibitor-1(TIMP-1) were detected before and after treatment, the degree of pain and clinical efficacy were compared.Results Compared with before treatment, levels of estradiol(E2),progesterone(P) and luteotropic hormone(LH) decreased in two groups(P<0.01), the levels of MMP-9, MMP-9/TIMP-1 decreased(P<0.01), levels of TIMP-1 increased(P<0.01), levels of CA125 decreased(P <0.01), and the maximum diameter of pelvic mass line decreased(P<0.01), dysmenorrhea pelvic pain, dyspareunia and VAS score decreased(P<0.01).Compared with the control group, levels of E2, P and LH in the research group were lower(P<0.01), the levels of MMP-9, MMP-9/TIMP-1 were lower(P<0.01), levels of TIMP-1 were higher(P<0.01), levels of CA125 were lower(P<0.01), the maximum diameter of pelvic mass line were lower(P<0.01), dysmenorrhea and pelvic pain and VAS scores were lower(P<0.01), and the effective rate of research group was higher(P<0.05).Conclusion Wendan Decoction plus Saffron in the treatment of endometriosis of uterus was effective, and it can reduce endometriosis, dysmenorrhea and pelvic pain degree, reduce pelvic mass, and may reduce the level of serum MMP-9 related.

OBJECTIVE:To study the effects of aripiprazole on PC12 cell injury induced by amyloid β-protein(Aβ25-35)and its mechanism. METHODS:PC12 cells were randomized into normal control group,model group (20 μmol/L Aβ25-35),aripiprazole low-concentration,medium-concentration and high-concentration groups(5,10,20 μmol/L aripiprazole+20 μmol/L Aβ25-35). These groups were cultured with culture medium containing relevant medicine for 48 h,with 6 wells in each group. The viability(optical density value)of PC12 cell was measured by MTT assay,and PC12 cell apoptosis was measured by Hoechst staining. The activi-ties of Caspase-3 and Caspase-9 were determined by spectrophotometry. The protein expression of Bcl-2,Bax and PI3K and the phosphorylation of Akt were assayed by Western blot assay. RESULTS:Compared with normal control group,optical density value of model group was decreased while apoptotic rate was increased;the activities of Caspase-3 and Caspase-9,and the protein expres-sion of Bax were increased;the protein expression of Bcl-2 and PI3K,the phosphorylation of Akt were decreased(P<0.01). Com-pared with model group,optical density value of aripiprazole low-concentration,medium-concentration and high-concentration groups were increased,while apoptotic rate and the activities of Caspase-3 and Caspase-9 were decreased;the protein expression of Bcl-2 and PI3K and the phosphorylation of Akt were enhanced;while the protein expression of Bax were decreased in aripiprazole medium-concentration and high-concentration groups(P<0.05 or P<0.01). CONCLUSIONS:Aripiprazole can suppress cell apop-tosis of PC12 cell induced by Aβ25-35,which is related to activating PI3K/Akt signal pathway.

BACKGROUND:Bioactive glass has good biocompatibility, which can promote the remineralization effects of demineralized enamel and enhance the resistance of enamel to erosion. OBJECTIVE:To evaluate the effect of bioactive glass toothpaste versus fluoride toothpaste on brushing abrasion of enamel after acid etching. METHODS:Fifty-six enamel specimens were prepared from bovine incisors, and were embedded in acrylic resin with exposed buccal surface. The exposed area was 6 mm×6 mm and two amalgam fil ings were placed into the enamel and polished. Al specimens were divided into seven groups with eight specimens each. In six groups, specimens were brushed with ordinary toothpaste, fluoride toothpaste, bioactive glass toothpaste immediately and 30 minutes after being eroded by the Sprite. The last one group was brushed with ordinary toothpaste without acid etching as control. The treatment course was cycled 60 times. The surface abrasion loss of the specimens between two amalgam fil ings compared with respective amalgam reference surfaces was final y observed and calculated under laser scanning confocal microscope. RESULTS AND CONCLUSION:The abrasion loss amount of teeth with no acid etching was significantly lower than that with acid etching (P<0.05). The abrasion loss amount of teeth brushed with bioactive glass toothpaste was less than that with fluoride toothpaste at the same brushing time (P<0.05). For the same toothpaste, the abrasion loss amount of teeth brushed 30 minutes after eroded was less than that bushed instantly after eroded (P<0.05). Use of bioactive glass toothpaste can effectively reduce enamel loss caused by acid etching and brushing. The loss amount can also be reduced by brushing teeth 30 minutes after acid etching.
