Objective To investigate the Toxoplasma gondii infection situation and relative factors in reproductive women in Shandong area,so as to provide the evidences for establishing strategies for reducing the birth defects and improving the quality of population. Methods A total of 5 386 reproductive women who visited hospitals at county and city levels in Shandong region from January 2013 to December 2015 were treated as the research objects,and their venous blood samples were collected to de?tect the antibodies(IgG and IgM)against T. Gondii in serum. Meanwhile,the related risk factors of T. gondii infection were sur?veyed by questionnaires. Results Among the 5 386 reproductive women,623 ones were positive for IgG antibody and the posi?tive rate was 11.56%,and 328 ones were positive for IgM antibody and the positive rate was 6.21%. The single factor analysis showed that the pregnant status(χ2 =13.12,P<0.01),whether the residences were in downtowns or counties(χ2 =6.27, P<0.05),whether having animal contact history(χ2=10.46,P<0.01),and whether eating half?baked foods(χ2=21.19, P < 0.01)were related to T. gondii infection. Conclusions The T. gondii infection rate of reproductive women in Shandong Province is high;the related risk factors include pregnant status,residence,degree of intimate contact with animal,and wheth?er eating half?baked foods. It suggests that the detection of T. gondii infection and health education in reproductive women should be strengthened.

Objective To explore the shape change characteristics of Oncomelania hupensis snail shell after the snails being passively migrated into Shandong intake area of the South-to-North Water Diversion Project. Methods The snails raised on the Dushan island in Weishan Lake region were captured,and 115 the first filial generation snails and 107 the second filial generation ones were selected. The length and width of shells and apertures,and the labial ridge thickness of those snails were measured,the longitudinal rib number of snail spiral was counted,and 107 parental snails were chosen as controls. Results The labial ridge thickness of the filial generation snail was significantly reduced with the increase of algebras,and the labial ridge thickness among the 3 generations had a significant difference(P<0.01). Both the length of snail shell and the width of snail apertures were de-creased,while the width of snail shell,the length of snail apertures,the multiplication product of snail aperture’s length and width and the longitudinal rib number of snail spiral were all increased. Conclusion The body size of Oncomelania snails in Weishan Lake region becomes smaller,and their shells become thinner,which indicates that the environment of the lake region is not suitable for snail breeding,and the snails have natural decay tendency with the extension of time.

Objective :
To explore the effect of negative pressure sealing drainage on the treatment of maxillofacial-neck-mediastinal infection in multiple spaces.
Methods:
Vacuum sealing drainage (VSD) was applied in five patients with maxillofacial-neck-mediastinal infection caused by odontogenic infection accompanied by diabetes or renal failure and other systemic diseases. After extensive debridement, a negative pressure drainage sponge was placed in the pus cavity and then the wound was closed. Continuous negative pressure drainage was continued after the operation. At the same time, multidisciplinary consultation was applied to control basic diseases and, strengthen anti-inflammatory responses, and nutrition and other systemic treatments were applied.
Results:
Four patients underwent continuous negative pressure drainage and successful removal of the negative pressure sponge after inflammatory symptoms subsided. One patient′s inflammatory symptoms became more serious after the operation, and we performed another operation to change the placement of the negative pressure sponge. All 5 patients underwent VSD with negative pressure sponge replacement ranging from 1 to 3 times during treatment. After multidisciplinary consultation, they were all cured and discharged from the hospital.
Conclusion
For infection of the mediastinum, maxillofacial region and neck, local treatment and systemic treatment are emphasized, as well as the treatment of infected lesions and basic diseases. Negative pressure closure and drainage technology promotes the alleviation of inflammation, and multidisciplinary combined treatment is beneficial for the control of basic diseases.

Objective:To analyze the influence of factors before initiation of extracorporeal cardiopulmonary resuscitation (ECPR) on the prognosis of patients, so as to explore the intervention timing and improvement strategy of ECPR.Methods:A retrospective analysis was performed on 29 patients who underwent ECPR in the First Affiliated Hospital of Hunan Normal University (Hunan people's Hospital)from July 2018 to April 2021. Patients were divided into the survival group ( n = 13) and death group ( n = 16) according to whether they survived at discharge. The duration of conventional cardiopulmonary resuscitation (CCPR), initial heart rate before ECPR, the ratio of out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA), and the ratio of transported cases outside the hospital were compared between the two groups. According to different CCPR time, the patients were divided into the ≤45 min group, 45-60 min group and >60 min group to compare the hospital survival and sustained return of spontaneous circulation (ROSC) rate . According to the location of cardiac arrest, the patients from emergency department and other department were divided to compare the survival of IHCA. Results:The total survival rate was 44.83%, the average duration of extracorporeal membrane oxygenation (ECMO) was 114 (33.5, 142.5) h, and the average duration of CCPR time was 60 (44.5, 80) min. The duration of ECMO was longer in the survival group than in the death group ( P = 0.001). The duration of CCPR (the time from CPR to ECMO) in the survival group was significantly shorter than that in the death group ( P = 0.010). Patients with defibrillatory rhythm had higher hospital survival rate ( P = 0.010). OHCA patients had higher mortality than IHCA patients ( P = 0.020). Mortality of patients transferred from other hospitals was higher ( P = 0.025). Hospital survival and ROSC decreased in turn by CCPR duration ≤ 45 min, 45-60 min, and > 60 min ( P = 0.001). The location of CA occurrence had no impact on the hospital survival rate of IHCA patients ( P=0.54). Conclusions:Hospital survival of ECPR is higher than that of CCPR. ECPR is effective for refractory cardiac arrest. The prognosis of ECPR is significantly related to the duration of CCPR, initial heart rate, and location of CA. Education and team training should be strengthened to improve the survival rate of ECPR.
