Objective To investigate the value of the human chorionic gonadotropin(hCG)stimulation test in the diagnosis of disorder of sexual development(DSD)in children.Methods A retrospective analysis was conducted on 132 children with DSD.According to the karyotype,they were divided into three groups:46,XX group(n=10),46,XY group(n=87),and sex chromosome abnormality group(n=35).The above groups were compared in terms of sex hormone levels before and after hCG stimulation test,and the morphological manifestation of the impact of testicular tissue on the results of the hCG stimulation test was analyzed.Results There was no significant difference in the multiple increase of testosterone after stimulation among the three groups(P>0.05).In the 46,XY group,the children with 5α-reductase type 2 deficiency had a testosterone-to-dihydrotestosterone ratio higher than that of the 46,XY DSD children with other causes.Morphological analysis showed that DSD children with testicular tissue demonstrated a significantly higher multiple increase in testosterone after stimulation compared to children without testicular tissue(P<0.05).Conclusions The hCG stimulation test has an important value in assessing the presence and function of testicular interstitial cells in children with different types of DSD,and it is recommended to perform the hCG stimulation test for DSD children with unclear gonadal type.[Chinese Journal of Contemporary Pediatrics,2024,26(2):158-163]

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

The Philippines has an increasingly aging population thereby increasing the demand for healthcare and support from families. Studies showed that the family is the main caregiver of elderly parents/adults as dictated by the Filipino culture of filial piety and respectful behavior towards older people. However, this caring culture is now slowly declining, and Filipino older adults also experience abuse, exploitation, and other forms of neglect from their families. This special article described that the declining caring culture was due to deteriorating family values and societal influences brought about by modernization. This paper also highlights the crucial role of the family and the community in inculcating the preservation of this valued caring Filipino culture, especially among the youth. In cases where senior citizens are being abused and neglected by their families, the state steps in to safeguard the welfare and protection of Filipino senior citizens. Enacted and promulgated laws ensure social justice and protection of human dignity among Filipino older adults as well as the provision of socioeconomic and health needs. In conclusion, the preservation of a caring culture through educating the youth coupled with the implementation of enacted and promulgated laws of the country ensures the quality of aging life among Filipino older adults.

Pregnancy is a critical period in every woman's life. The health of both the mother and her unborn child is at stake, with poor access to needed prenatal care services. Obtaining prenatal care is affected by the pregnancy literacy of the expectant mother. However, the assessment tool for health literacy among Filipino pregnant women is limited. This paper aimed to examine existing maternal health literacy instruments. Hopefully, an adopted tool can be found for assessing prenatal health literacy. After examining existing maternal health literacy tools, 18 questions were suggested that can be further modified before they are used for Filipino pregnant women to assess their prenatal health literacy.

Objective To explore the mechanism of the therapy of promoting blood circulation and nourishing yin(PBCNY)in improving spermatogenesis in rats with varicocele based on Bcl-2/Bax pathway.Methods Thirty 8-week-old male SD rats were randomly divided into six groups(five rats per group):sham,model,levocarnitine(1.0 g/kg),and PBCNY low-dose(5.2 g/kg),PBCNY medium-dose(10.4 g/kg),and PBCNY high-dose(20.8 g/kg)groups.Apart from the sham group,all the groups were built a varicocele model by the classical Turner method.After 4 weeks,the sham group and model group were gavaged with normal saline,and the remaining groups were given with levocarnitine or different doses of PBCNY decoction once a day for 4 weeks.At the end of gavage,the sperm quality of rats in each group was detected by a computer-assisted sperm analyzer,and HE staining was used to observe the testicular tissue morphology of rats in each group and performed with Johnsen score.TUNEL method was used to detect apoptosis,RT-qPCR was used to detect Bcl-2 and Bax mRNA expression,and immunohistochemical method was used to detect cytochrome C protein expression.Results Compared to the sham group,sperm total count,motility rate and percentage of sperm with grade(a+b)motility were lower in the model group of rats(P<0.05).HE staining showed disturbed arrangement of seminiferous tubules in the testicular tissue with significant changes and decreased Johnsen score(P<0.05).The result of TUNEL assay showed that the apoptosis rate was increased in the model group(P<0.05).Bax mRNA expression was increased in testicular tissue(P<0.05).The result of immunohistochemistry showed that the positive expression of cytochrome C was increased in the model group(P<0.05).Compared with the model group,the rat sperm total count in the PBCNY medium-dose group,motility rate in the PBCNY low-and medium-dose groups,and percentage of sperm with grade(a+b)motility in the PBCNY low-dose group increased(P<0.05);the pathological structure of rat testis had different degrees of improvement,and Johnsen score increased in the PBCNY medium-dose group(P<0.05);the apoptosis rate of testicular cells decreased in the levocarnitine group and all doses of PBCNY groups(P<0.05);the expression of Bcl-2 mRNA increased in the PBCNY low-dose and high-dose groups(P<0.05),and the expression of Bax mRNA decreased in the levocarnitine group and the PBCNY medium-dose group(P<0.05);the positive expression of cytochrome C decreased in the PBCNY medium-dose group(P<0.05).Conclusion The therapy of PBCNY can improve sperm quality,repair damaged testicular tissue structure and improve spermatogenic function in rats with varicocele,and its mechanism of action may be related to the activation of Bcl-2/Bax pathway and inhibition of cell apoptosis.
