Sperm DNA fragmentation index (DFI) refers to the percentage of DNA strand breaks in the total sperm. Many studies suggest that elevated DFI can lead to male infertility and early spontaneous abortion. High-DFI patients are more likely to fail in assisted reproduction and preliminary treatment or prevention methods have been developed for this population. This review focuses on the impact of DFI on clinical pregnancy outcomes and progress in the studies of its treatment.

To investigate amethod which could prolong the efficient time of morphine and decrease side effect. Met hods:100 patients were randomly divided into four groups, receiving the different dispensation of analgesia. Analgesic solutions were given into epi dural space 510 minutes before operation was finished. Analgesic efficiency, efficient time, and side effects were recorded. esult: Sol utions diluted with hypertonia glucose injection might prolong the efficient time obviously (P＜0.01). When combined with bupivacaine or scopolamine the sid e effects were decreased. Conclusion: Morphine combined wi th bupivacaine or scopolamine diluted with hypertonis glucose injection, used in epidural analgesia, can bring longer efficient time and less side effects.

Intracerebral delivery of drugs for the treatment of central nervous system disorders is usually limited by the blood-brain barrier (BBB). Transdermal drug delivery systems (TDDS) have the advantage of improving patient compliance and avoiding first-pass effects compared to intravenous, oral and intranasal drug delivery, and are an emerging non-invasive drug delivery route that facilitates long-term drug delivery to patients. The discovery of direct subcutaneous targeting of lymphatic pathways to brain tissue has made TDDS a new brain-targeted drug delivery strategy. At the same time, the development of nano-delivery technology has further facilitated the application of TDDS for targeted drug delivery to the brain. This review summarizes the mechanism of transdermal drug delivery into the brain and the application of TDDS in the treatment of brain diseases, providing new ideas and methods for the treatment of central nervous system diseases.

Abstract: Objective　To analyze the epidemiological characteristics of late diagnosed HIV/AIDS cases (LD) in Sanya from 2010 to 2021, and to provide evidence for reducing the LD rate. Methods　The database was downloaded from the AIDS Prevention and Control Information System of China's Disease Prevention and Control Information System and newly reported HIV/AIDS cases between 2010 and 2021 in Sanya were included, identified LD according to the LD criteria proposed by Chinese Center for Disease Control and Prevention in 2014 and analyzed the relevant factors of LD. Results　From 2010 to 2021, a total of 710 research objects were included in this study. The proportion of LD was 33.4% (237/710), and decreased from 95.5% to 22.4% between 2010 and 2021 (χ2trend=34.777, P<0.001). Ethnic groups, educational level, sample sources and confirmed date were the relevant factors of LD of HIV/AIDS in Sanya City. The proportion of LD was 56.8% in Li ethnic group, which was higher than that in Han ethnic (OR=2.253, 95%CI=1.361-3.670). The proportion of LD of patients who were middle school and less was 55.5%, which were more likely to be LD than high school or above (OR=1.722, 95%CI=1.072-2.765). The proportion of LD was 56.8% in patients whose samples were from medical institutions or testing consultation were more likely to be LD than MSM (OR=5.564, 95%CI=3.278-9.444; OR=2.204, 95%CI=1.239-3.923). Compared with patients who were confirmed between 2018-2021, the patients derived from 2010 to 2013 had higher LD (OR=2.246, 95%CI=1.311-4.488). Conclusion　The LD of HIV/AIDS in Sanya cannot be ignored, especially the HIV/AIDS from counseling and testing and medical institutions. We should strengthen HIV testing, strengthen health education.

OBJECTIVE To investigate clinical features and etiology of inhalation pneumonia.METHODS Totally 108 cases of inhalation pneumonia during from Jan 2000 to Dec 2005 were completely surveyed and analyzed. RESULTS There were underlying diseases and susceptible factors, and it was not typical in their clinical signs and symptoms.Totally 177 pathogens were isolated from sputa. There were 96 strains of Gram-negative bacilli (54.2%), 41 strains (23.2%) of Gram-positive cocci, and 40 strains (22.6%) of fungi. The 45 cases (41.7%) were with polyinfections, and 19 cases (17.6%) with double infections.CONCLUSIONS We should enhance diagnosis of inhalation pneumonia, make rational use of antibiotic, and take vigorous precautions against inhalation pneumonia.

M PU employed as control center,the nerve stimulator can produce different stimul ation modes easily.The high-quality constant-current pulse and the safety of th e patient are ensured through two-steps current stabilizer,pulse width monitor and the float to ground.Both needle electrode and surface electrode can be used to achieve supramaximal stimulation.
