Objectives To understand the control and prevention status of water-borne endemic fluorosis in Jiangxi Province, in order to provide a scientific basis for evaluate and perfect the strategies in control and prevention of the disease. Methods According to monitoring project of national water-borne endemic fluorosis, three villages were chosen to investigate the status and the fluoride content of fluorosis villages with water-improving and defluoridation projects in Yushui district and Ningdu county of Jiangxi Province. Investigation consisted of the status of dental fluorosis of children aged from 8 to 12 years and adult skeletal fluorosis, as well as fluoride content of drinking water and urinary fluorine. The standard detection methods of domestic drinking water was used for water fluoride content detection, fluoride selective electrode was chosen for urinary fluorine detection, Dean detection method was used to determine dental fluorosis, and diagnostic criteria of endemic skeletal fluorosis was chosen for diagnose of skeletal fluorosis. Results In fluorosis villages with water-improving and defluoridation projects which operated normally, the fluoride content of drinking water was lower than 1.00 mg/L. In fluorosis villages with water-improving and defluoridation projects which never operated normally, the average fluoride content of drinking water was 1.76 mg/L. The detection rate of dental fluorosis of children aged 8-12 years was 12.50%(22/176). A total of 294 adults were examined by X-ray, 3 adults were diagnosed as skeletal fluorosis, and the detection rate was 1.02%. A total of 294 adult urine samples were tested. The urinary fluoride content varied from 0.28 to 7.74 mg/L, and the geometric mean was 1.10 mg/L. Conclusions The illness condition of water-borne endemic fluorosis has been under control effectively. The maintenance of water-improving and defluoridation projects and surveillance were main tasks in control and prevention of the disease in the future.

Objective To observe the effects of mirtazapine to improve the life quality of malignant tumor patients with moderate or severe depres-sion. Methods Patients with mood disorders screened by the physician were then graded by the Hamilton Depression Scale(HAMD)under the tu-telage of ward psychological consultant. Fifty patients with moderate or severe depression were selected by psychological doctors and recruited for the study. After obtaining consent,the patients received 15-60 mg/d mirtazapine every night for 9 weeks. According to the Quality of Life Rating Scale (QOL),the scores of these patients were evaluated at the pretreatment,the 3rd week and the 9th week of the post-treatment. Then,the life quality conditions before and after treatment were revaluated. Results The scores of HAMD were 33.16±7.25,28.74±6.24,and 22.58±6.71 at the pretreat-ment,the 3rd week and the 9th week of the post-treatment,respectively. There were significantly different among the HAMD scores at the pretreat-ment,the 3rd week and the 9th week of the post-treatment.(F=30.99,P<0.01). The scores of HAMD were improved significantly between the pre-treatment and the 3rd week of the post-treatment(P<0.05). The scores of HAMD were also improved significantly between the 3rd week and the 9th week of the post-treatment(P<0.05). After treatment by mirtazapine,the appetite,spirit,sleep,fatigue,pain,the reorganization of cancer,the attitude towards treatment,the side effect of treatment and the facial expression were significantly improved(P<0.01). Conclusion Mirtazapine could improve the life quality of malignant tumor patients with moderate or severe depression.

Myopic foveoschisis is a disease caused by abnormal vitreoretinal interface status and progressive posterior scleral staphyloma.Its occurrence and development are associated with centripetal traction (posterior vitreous cortex,internal limiting membrane and stiff retinal vessel)and centrifugal traction (increasing axial lengths and posterior scleral staphyloma).Currently vitrectomy is the major option to treat this condition as it can alleviate or eliminate centripetal and centrifugal traction.However as myopic foveoschisis is a life-long progressive degenerative disease,often with abnormalities in retinal pigment epithelium,choroid and sclera;the therapeutic effect of current surgical strategy (vitrectomy or scleral surgery,or combined surgery)is limited and unsatisfactory.A full assessment macular structure,function and related factors before surgery is helpful to predict the anatomical and functional prognosis.

Objective To construct pEGFP-N1-TGF-β1 recombinant plasmid and transfect it into primary cultured neonatal piglet type Ⅱ alveolar epithelium cell (AEC-Ⅱ) by using lipofectamine 2000,in order to provide basis of methodology for producing recombinant plasmids for transplantation of transfected AEC-Ⅱ into ALI/ARDS animal model lungs.Methods PCR primers were designed to amplify the human TGF-β1 cDNA fragment from plasmid.XhoI and EcoRI were used for double digesting the empty plasmid pEGFP-N1 and cDNA fragment of human TGF-β1.Then the products of double enzyme digestion by using T4 DNA ligase were connected and transformed into DH5α and cultured over night for 16 hours.The structure of recombinant plasmid was identified by using PCR and base sequencing to verify the correctness of pEGFP-N1-TGF-β1 recombinant plasmid.It was then transfected into primarily cultured AEC-Ⅱ by lipofectamine2000 mediated transfection and cultured for another 48 hour.Plasmid DNA (pEGFP-N1-TGF-β1 recombinant plasmid) and lipofectamine 2000 were added into serum-free DMEM respectively,then DNA suspension and Lipofectamine 2000 suspension were blended together and added into cells.After 24-48 hours later,the expression level of enhanced green fluorescent protein (EGFP) was evaluated under fluorescence microscope.Results The structure of vector was verified as pEGFP-N1-TGF-β1 recombinant plasmid by using PCR and base sequencing.Green fluorescence found in some cells showed that the pEGFP-N1-TGF-β1 recombinant plasmids had been successfully transfected into primary cultured AEC-Ⅱ,however,the transfection efficiency still need tobe further improved such as repeating the transfection procedure once again or using adenovirus mediated transfection method to improve the efficiceny and to transplant the cells into animal lungs eventually.Conclusions pEGFP-N1-TGF-β1 recombinant plasmid was successfully constructed and,for the first time,transfected into primarily cultured AEC-Ⅱ of newborn piglets.This established method should be useful for investigation of therapeutic effect and outcomes of lung with experimental acute lung injury.

Objective To study the related factors of hemorrhage of uterine scar again after cesarean section,available for peer exchange.Methods A retrospective analysis of clinical data of 650 patients with scar uterus again cesarean section patients,analysis of postoperative hemorrhage patients,the causes of bleeding.They were divided into placental group (n =6),incision dehiscence group (n =7),uterine atony group (n =17)according to the causes of hemorrhage,and related factors of postoperative bleeding were analyzed.Results The bleeding volume of the placental group in operation[(2 500 ±500)mL]was higher than the uterine atony group[(1 300 ±400)mL] and the incision dehiscence group[(700 ±200)mL].The bleeding volume of the uterine atony group was higher than the incision dehiscence group (t =10.29,5.56,4.33,all P <0.05).The bleeding volume of the uterine atony group after operation[(100.09 ±36.45)mL]was higher than the placental group[(90.71 ±20.31)mL]and the uterine atony group[(81.23 ±30.34)mL].The bleeding volume of the placental group after operation were higher than the uterine atony group (t =3.94,3.02,2.78,all P <0.05).4 cases of hysterectomy,3 cases of conservative surgery in placental group.1 case of hysterectomy,16 cases of conservative surgery in uterine atony group.7 cases conservative surgery in incision dehiscence group.Conclusion placental factors,uterine atony,incision dehiscence all can lead to scar uterus again cesarean section hemorrhage.We should also strengthen the clinical prevention work,and actively take relevant measures,reduce postoperative bleeding risk,to ensure the safety of the mother and infant.

Thirty-one children suffered from speech retardation were found to have normal hearing level through ABR and/or acoustic immittance tests. Some of them were further checked by psychiatrists and pediatricians. The results demonstrate that among reasons for speech retardation in children,autism and mental retardation are important factors that can not be ignored. A-mong children with unclear diagnosis .some harmful factors were found on themselves and in surroundings. We emphasize that for children with speech retardation,not only hearing disorders,but also other factors should be considered.
