Objective To investigate the relationship between the parameter of P100 elicited by pattern stimuli, spatial frequency and visual acuity in the posttraumatic eyes. Methods 81 eyes sustained blunt injury in outpatients were enrolled from West China Hospital, Sichuan University. The control group was composed of 199 eyes without disease or trauma. Different P100 wave including amplitude and latency were recorded in each eye stimulated by reversal pattern with 5 - sized checkerboards. The data were processed by SPSS to describe the relationship between the visual acuity and the parameter of P100 wave. A linear and regression analysis was done in the statistic procedure. Results There was a high correlation between spatial frequency ( X) and the log visual acuity ( Y). Regression equations were deduced for evaluating the visual acuity. There was a correlation between the latency of P100 wave (X) and the log visual acuity (Y) in all the examined eyes. Conclusion The established regression equations can be used to evaluate the visual acuity as an accurate and objective method. There is a promising future of its application in the forensic clinical authentication of visual function.

Objective To observe the preventing effect of optimal programs (improving turn over postures and elongating the turn over intervals)in preventing pressure sore occurrence in patients with acute stroke. Methods Acute stage stroke patients (time from on-set less than or equal to one week)were selected and divided randomly into 4 groups, one group adopted 2.0 hours turn over intervals as the routine group, others adopted 2.5 hours, 3.0 hours, 3.5 hours turn over intervals as the study groups. The incidence of pressure sores and complications were recorded. Results None of the groups (2.0 h, 2.5 h,3.0 h, 3.5 h)suffered from pressure sores. The incidence of complications including malnutrition, pulmonary infections and constipations was not increased in the study groups either. Conclusions Optimal turn over nursing programs including elongating turn over intervals to 2.5h, 3.0h, 3.5h and adopting 30 degree lateral posture can effectively prevent occurrence of pressure sores in acute stroke patients.

Baicalein(BE), a natural flavonoid mainly extracted from Radix Scutellaria, has comprehensive pharmacological actions such as anti-inflammation, anti-virus and anti-cancer activities. It belongs to BCS class II compound with relatively low oral bioavailability. The current study aims to improve its aqueous solubility and dissolution and hence to enhance its oral absorption by cocrystallization technique. Slurry crystallization method was employed to prepare baicalein cocrystal with co-former caffeine(CA), followed by physicochemical characterizations with DSC, XRPD and FTIR. Compared to BE and physical mixture of BE and CA, BE-CA cocrystal had a significantly higher dissolution of BE. In addition, in comparison to BE, this cocrystal achieved reduced time to peak(tmax)as well as significantly higher peak plasma concentrations(cmax)and area under the curve(AUCs)for both BE and its active metabolite baicalin(BI)in rats, suggesting enhanced the oral bioavailability of BE.

Objective:To explore the application effect of pelvic floor outpatient intervention during pregnancy on vaginal delivery of full-term primiparous women.Methods:Single birth primipara who were willing to establish a card and have a desire to give birth naturally in the First People's Hospital of Longquanyi District from January 2021 to December 2021 were divided into odd and even number groups according to the order of filing:the odd group received routine obstetric outpatient management and pelvic floor outpatient intervention(Kegel exercise joint perineum massage)in 200 cases(research group),and even number group received routine obstetric outpatient management in 200 cases(control group).The incidence of vaginitis,cesarean section rate,vaginal delivery rate,obstetric laceration,vaginal midwifery rate,perineal incision,delivery outcome and the length of perineal body and reproductive hiatus before and 42 days after delivery,vaginal width andother vaginal delivery complications(urina-ry retention and puerperal hemorrhoids)were compared between the two groups.Results:87 cases were includ-ed in the final study group,while 104 cases were included in the control group.The perineal incision rate,perineal integrity rate,vaginal midwifery rate,l degree and Ⅱ degree perineal laceration rate,postpartum hemorrhage in the study group were better than those in the control group(P<0.05).The length of reproductive hiatus 42 days after delivery in the study group was shorter compared with that in the control group(P<0.05).There were no signifi-cant differences in the incidence of vaginitis,cesarean section rate,time of the second stage of labor,vaginal wall laceration rate,Apgar score of newborns neonatal birth trauma rate,urinary retention,puerperal hemorrhoids,post-partum vaginal width and perineal body length between the two groups(P>0.05).Conclusions:Pelvic floor outpa-tient intervention during pregnancy can reduce the harm caused by vaginal delivery in full-term primiparas to a cer-tain extent,and does not increase the incidence of neonatal delivery complications,it is worthy of clinical promotion.

Objective:To analyze the use of policy tools for rural-oriented tuition-waived medical student training policy and to provide relevant suggestions for the continuous promotion of the policy.Methods:With "rural-oriented tuition-waived medical students" as the key word, the policy texts were collected and screened from government portals. Using ROTHWELL disaggregated method to build the rural order directional medical students training policy analysis framework, applying Excel 2019 software for classification and coding of policy texts.Results:A total of 13 rural-oriented medical student training policy texts were screened and obtained. The X dimension of the policy analysis framework for rural order-oriented medical student training included three policy tools, namely, supply, environment and demand, and the Y dimension included three policy objectives, namely, available, usable, and retained. In X dimension, environmental policy tools were most frequently used. In Y dimension, the "retained" target had the highest frequency of use.Conclusion:There were differences in the frequency of using policy tools for targeted medical student cultivation in different policies. The frequency of using environmental tools is higher, which highlighted the attention of the state to medical and health services. The internal structure of policy tools is unbalanced, so the configuration of supply-oriented policy tools should be optimized, and the construction of demand-oriented policy tools should be emphasized. It is suggested to continuously optimize the combination of policy tools, improve the compatibility between policy tools and rural order-oriented medical student training, and pay attention to the sustainability of policy tools.
