Objective:
To investigate the relationship between total homocysteine (tHcy) levels and sarcopenia among the elderly, so as to provide insights into the prevention and treatment of sarcopenia.
Methods:
The elderly aged 65 years and older who participated in the physical examination of Shibantan Township Health Center in Xindu District, Chengdu City from April to June 2021 was selected as the study subjects. The elderly with sarcopenia (diagnosed according to the diagnostic criteria of the Asian Sarcopenia Working Group in 2019) and non-sarcopenia were matched 1︰1 by gender and age (±2 years). Demographic information, skeletal muscle mass, skeletal muscle strength and tHcy were collected through questionnaire surveys, physical examination and laboratory testing. Multivariable conditional logistic regression model was used to explore the relationship between tHcy and sarcopenia.
Results:
A total of 320 individuals, including 160 sarcopenia patients and 160 non-sarcopenia individuals, were investigated. There were 138 males (43.13%) and 182 females (56.87%), with a median age of 71.00 (interquartile range, 6.00) years. There were 57 drinkers (17.81%), 78 smokers (24.37%), 173 cases of hypertension (54.06%) and 124 cases of hyperhomocysteinemia (38.80%). Multivariable conditional logistic regression analysis showed that elevated tHcy was associated with an increased risk of sarcopenia (OR=1.107, 95%CI: 1.024-1.197), after adjusting for smoking, alcohol consumption, hypertension, waist circumference, neck circumference, body mass index, platelet count and high density lipoprotein cholesterol.
Conclusion
Elevated tHcy is associated with sarcopenia, and intervention should be carried out for the elderly with higher tHcy.

BACKGROUND:Establishment of in vitro culture system of human placental microvascular endothelial cel s with high purity is very important. In recent studies, some scholars have successful y obtained a large number of placental microvascular endothelial cel s by three-stepenzyme digestion and magnetic separation method, but the procedures were extremely complex and it had great damage to the cel s. Therefore, how to separate human placental microvascular endothelial cel s easily and obtain high-purified cel s has become a research hotspot.
OBJECTIVE:To investigate an efficient method to isolate and purify human placental microvascular endothelial cel s from early vil us microvessels, observe the cel growth and identify the cel s.
METHODS:The vil i from normal early pregnancies (6-8 weeks) after artificial abortion were col ected aseptical y. Using two-step digestion procedure and discontinuous Percol density gradient centrifugation method, human placental microvascular endothelial cel s were obtained. Then the cel s were identified by trypsin digestion method and repeated adherence method.
RESULTS AND CONCLUSION:Human placental microvascular endothelial cel s were isolated successful y from early vil i. The primary cel s adhered to the wal s after inoculated for 24 hours and entered logarithmic phase at 10 days. 80%of the cel s achieved a confluence at 12-13 days after inoculating. The subculture cel s grew swiftly with the typical cobblestone appearance. Immunofluorescence staining showed that, cultured human placental microvascular endothelial cel s demonstrated a strong positive reaction to von Wil ebrand factor antigen and CD31, accounting for 100%. MTT assay results showed that, human placental microvascular endothelial cel s at passage 5 exhibited an S-shaped growth curve. High-purity human placental microvascular endothelial cel s can be obtained by proteolytic enzymes digestion and discontinuous Percol density gradient centrifugation method, and the purity is detected by trypsin digestion method and repeated adherence method.

Objective:To evaluate the feasibility and effectiveness of sing-port robot-assisted laparoscopic radical prostatectomy(sp-RALP) through different approaches.Methods:The data of 115 patients who underwent sp-RALP through different approaches from May 2018 to June 2020 were retrospectively reviewed. In our study, 92 cases through extraperitoneal approach, 10 through transperineal approach and 13 though transvesical approach. Preoperative, intraoperative and early postoperative outcomes after various approaches were collected and analyzed. The mean age was 67(52-84) years, mean preoperative body mass index was 24.44(19.52-32.33) kg/m 2. Patients were graded as cT 1-3aN 0M 0 with no signs of regional lymph node invasion or distal metastasis. The median preoperative PSA was 9.77(6.54, 15.32) ng/ml. Results:All 115 sp-RALP were successfully completed with no conversion to open surgery or additional ports being placed. The mean operative time was 91.8(40-200)min, with 88.0(40-200)min for extraperitoneal approach, 132.5 (90-190)min for transperineal approach and 87.3(60-150)min for transvesical approach. The mean estimated blood loss was 85.5 (45-400)ml, with 77.6(50-200)ml for extraperitoneal approach, 178.0(80-400)ml for transperineal approach and 70.4 (45-150)ml for transvesical approach. Of the 115 patients, 60.9% (70/115)were

Male infertility (MI) and male sexual dysfunction (MSD) can often coexist together due to various interplay factors such as psychosexual, sociocultural and relationship dynamics. The presence of each form of MSD can adversely impact male reproduction and treatment strategies will need to be individualized based on patients’ factors, local expertise, and geographical socioeconomic status. The Asia Pacific Society of Sexual Medicine (APSSM) and the Asian Society of Men’s Health and Aging (ASMHA) aim to provide a consensus statement and practical set of clinical recommendations based on current evidence to guide clinicians in the management of MI and MSD within the Asia-Pacific (AP) region. A comprehensive, narrative review of the literature was performed to identify the various forms of MSD and their association with MI. MEDLINE and EMBASE databases were searched for the following English language articles under the following terms: “low libido”, “erectile dysfunction”, “ejaculatory dysfunction”, “premature ejaculation”, “retrograde ejaculation”, “delayed ejaculation”, “anejaculation”, and “orgasmic dysfunction” between January 2001 to June 2022 with emphasis on published guidelines endorsed by various organizations. This APSSM consensus committee panel evaluated and provided evidence-based recommendations on MI and clinically relevant MSD areas using a modified Delphi method by the panel and specific emphasis on locoregional socioeconomic-cultural issues relevant to the AP region. While variations exist in treatment strategies for managing MI and MSD due to geographical expertise, locoregional resources, and sociocultural factors, the panel agreed that comprehensive fertility evaluation with a multidisciplinary management approach to each MSD domain is recommended. It is important to address individual MI issues with an emphasis on improving spermatogenesis and facilitating reproductive avenues while at the same time, managing various MSD conditions with evidence-based treatments. All therapeutic options should be discussed and implemented based on the patient’s individual needs, beliefs and preferences while incorporating locoregional expertise and available resources.
