Reporting a measurement procedure and its analytical performance following method evaluation in a peer-reviewed journal is an important means for clinical laboratory practitioners to share their findings. It also represents an important source of evidence base to help others make informed decisions about their practice. At present, there are significant variations in the information reported in laboratory medicine journal publications describing the analytical performance of measurement procedures. These variations also challenge authors, readers, reviewers, and editors in deciding the quality of a submitted manuscript. The International Federation of Clinical Chemistry and Laboratory Medicine Working Group on Method Evaluation Protocols (IFCC WG-MEP) developed a checklist and recommends its adoption to enable a consistent approach to reporting method evaluation and analytical performance characteristics of measurement procedures in laboratory medicine journals. It is envisioned that the Laboratory Evaluation and Analytical Performance Characteristics (LEAP) checklist will improve the standardisation of journal publications describing method evaluation and analytical performance characteristics, improving the quality of the evidence base that is relied upon by practitioners.

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.

Objective:To discuss the clinical manifestations, diagnosis and treatment of a patient with Allgrove syndrome.Methods:Retrospective analysis of the clinical data of a patient with Allgrove syndrome admitted to Gansu Provincial People's Hospital on August 8, 2018, and review of relevant literature.Results:The patient, female, 20 years old, presented with dysphagia for 10 years and aggravated for 4 years. No tears since childhood. The upper digestive tract barium meal showed that lower esophageal stenosis, a "beak" shaped change. Esophageal manometry suggested multiple peristalsis failures. Laboratory tests showed low plasma cortisol and high ACTH. The clinical diagnosis was Allgrove syndrome. POME was performed to improve dysphagia, and hormone replacement therapy was given. The symptoms were improved after long-term follow-up.Conclusion:Allgrove syndrome is a multisystem disease. The possibility of Allgrove syndrome should be vigilant when suspicious symptoms appear. If necessary, gene detection is helpful for early diagnosis.Treatment, which focuses on the appropriate management of the manifested signs and symptoms, requires the mutual assistance of multiple disciplines.

Objective:To comprehensively evaluate the quality of colonoscopy in Endoscopy Center of Gansu Provincial Hospital, and to provide baseline data and theoretical basis for evaluating the quality of digestive endoscopy in China.Methods:It is a single-center, retrospective and cross-sectional study. Data were collected from patients who underwent colonoscopy and received therapies in the Endoscopy Center of Gansu Provincial Hospital from 1st January to 31st December in 2021. The quality control indicators including polyp detection rate, adenoma detection rate, cecal intubation rate, and adequate intestinal preparation rate were analyzed to evaluate the quality of colonoscopy in the endoscopy center.Results:A total of 7 562 patients who underwent colonoscopy were included in this study, with the age of (51.61±13.59) years, including 4 286 males (56.7%) and 3 276 females (43.3%) . There were 4 924 (65.1%) outpatients and 2 638 (34.9%) inpatients. Procedures were completed by full-time endoscopists on 6 456 patients (85.4%) , and those were by gastroenterologists or proctologists on 1 106 patients (14.6%) . The overall adenoma detection rate, polyp detection rate, cecal intubation rate, and adequate intestinal preparation rate were 11.9% (900/7 562), 32.9% (2 488/7 562), 93.0% (7 030/7 562), and 91.3% (6 906/7 562) respectively. The male, the elder, in patients, and examined by full-time endoscopists were associated with higher adenoma detection rate and polyp detection rate with significant difference ( P<0.05). Conclusion:The cecal intubation rate and adequate intestinal preparation rate of colonoscopy in Gansu Provincial Hospital could meet the guideline standard, but the adenoma detection rate still needs to be further improved. The elder and male patients are the key population for colonoscopy screening. In addition, great importance should be attached to the standardized training of endoscopists to further improve the quality of colonoscopy.

【Objective】 To investigate the prognostic role of EHD3 and its association with immune cell infiltration in gastric cancer. 【Methods】 In this study, EHD3 expression was analyzed using RNA sequencing data from Cancer Genome Atlas (TCGA). Differential analysis, functional enrichment, immune infiltration, immune checkpoint exploration, and clinical baseline data analysis were performed. Independent prognostic factors were identified using univariate and multivariate Cox regression analysis; a column diagram model was developed and evaluated using C-index and calibration diagrams. 【Results】 EHD3 was significantly upregulated in STAD and functional enrichment analysis showed that EHD3 expression was associated with immune response, with most immune cells and immune checkpoints positively correlated with their expression. Cox regression showed that EHD3 was an independent prognostic factor in STAD patients (HR=2.112, 95% CI: 1.340-3.327, P=0.001). 【Conclusion】 EHD3 is considered to be a novel prognostic biomarker for STAD patients, and this study provides a potential therapeutic target for STAD treatment.

Angong Niuhuang Pills(AGNHP) are effective in clearing heat, removing the toxin, and eliminating phlegm for resuscitation. Clinically, it is widely used to treat various diseases such as febrile convulsion due to heat attacking pericardium, but its therapeutic effects on heart failure(HF) have not been well recognized. In this study, the profiles of differential metabolites regulated by AGNHP were identified by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS). The underlying mechanism of AGNHP against HF was illustrated based on the integrated analysis of pharmacological data and metabolic molecular network. The HF model was induced by isoproterenol in mice. After oral administration of AGNHP for one week, cardiac functions in HF mice were evaluated by echocardiography, and serum samples of mice were collected for metabolomics analysis. Eight differential metabolites of AGNHP against HF were screened out through partial least square discriminant analysis(PLS-DA) and input into MetaboAnalyst for the analysis of metabolic pathways. Moreover, the critical metabolic pathways regulated by AGNHP were enriched according to the potential targets of major compounds in AGNHP. After AGNHP treatment, the recovered index of relative content of some metabolites underwent cross-scale fusion analysis with therapeutic efficacy data, followed by "compound-reaction-enzyme-gene" network analysis. It is inferred that the anti-HF effects of AGNHP may be attributed to the metabolism of arachidonic acid, amino acid, glycerophospholipid, and linoleic acid. The cross-scale polypharmacological analysis method developed in this study provides a new method to interpret scientific principles of AGNHP against HF with modern technologies.

Objective To investigate the effect of serum containing Huangqi decoction on the proliferation, migration, and tubulogenesis of rat liver sinusoidal endothelial cells (LSECs) induced by vascular endothelial growth factor (VEGF) and its mechanism of action based on the protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway. Methods The serum containing Huangqi decoction was prepared, and rat LSECs were isolated and cultured in vitro . Then rat LSECs were randomly divided into blank group, VEGF group, serum control group, and low-, middle-, and high-dose serum containing Huangqi decoction groups. MTT colorimetry, Transwell assay, and tubulogenesis assay were used to measure the proliferation, migration, and tubulogenesis abilities of LSECs in each group, and Western Blot was used to measure the protein expression levels of platelet endothelial cell adhesion molecule-1 (CD31), endothelin-1 (ET-1), and endothelial nitric oxide synthase (eNOS), as well as AKT, phosphorylated-AKT (p-AKT), mTOR, and phosphorylated mTOR (p-mTOR) in the AKT/mTOR signaling pathway. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the Tukey's test was used for further comparison between two groups. Results Compared with the blank group, the VEGF group and the serum control group had significantly promoted proliferation, migration, and angiogenesis of rat LSECs (all P < 0.05), and Western Blot showed significant increases in the expression levels of CD31, ET-1, eNOS, and AKT/mTOR signaling pathway-related proteins (all P < 0.05). There were no significant differences in the above indices between the VEGF group and the serum control group (all P > 0.05). Compared with the serum group, the middle- and high-dose serum containing Huangqi decoction groups had significantly inhibited proliferation, migration, and angiogenesis of rat LSECs induced by VEGF (all P < 0.05), and Western Blot showed significant reductions in the expression levels of CD31, ET-1, eNOS, and AKT/mTOR signaling pathway-related proteins (all P < 0.01). Conclusion A relatively high dose of serum containing Huangqi decoction can significantly inhibit the proliferation, migration, and tubulogenesis of rat LSECs induced by VEGF, possibly by regulating the AKT/mTOR signaling pathway.

Objective: To explore the protective mechanism of acupuncture plus mild hypothermia for cerebral ischemia-reperfusion injury (CIRI) by observing the effects of acupuncture plus mild hypothermia on miRNA-204 and its target gene expressions in CIRI rat brain tissues. Methods: Sixty Sprague-Dawley rats were divided into a blank control group, a sham operation group, a model group, an acupuncture group, a mild hypothermia group and an acupuncture plus mild hypothermia group according to the random number table method (n=10). Except for the blank control group and the sham operation group, rats in the other 4 groups received CIRI modeling. After the model was successfully established, rats in the blank control group were bred routinely for 72 h without any interventions; rats in the sham operation group and the model group were bred routinely for 72 h, and only received binding without other interventions after surgery; rats in the acupuncture group were bred routinely for 72 h, and received acupuncture at Dazhui (GV 14), Baihui (GV 20) and Shuigou (GV 26) after binding; rats in the mild hypothermia group were bred routinely for 72 h, and received mild hypothermia intervention for 72 h after binding; rats in the acupuncture plus mild hypothermia group were bred routinely for 72 h, followed by receiving acupuncture as in the acupuncture group and mild hypothermia therapy as in the mild hypothermia group after binding. The neurological impairment score, cerebral infarction area ratio, the expressions of miRNA-204 and its target genes including Map3k8, Ntrk2 and Ppp3r1 in the ischemic hippocampus of each group were observed after 72 h of intervention. Results: Before intervention, compared with the blank control group and the sham operation group, the neurological impairment scores and the infarction area ratios of the modelled rats were statistically significantly increased (all P<0.01), indicating that the model was successful. After intervention, compared with the model group, the neurological impairment scores of the three intervention groups were significantly reduced (all P<0.01); compared with the acupuncture group and the mild hypothermia group, the infarction area ratio in the acupuncture plus mild hypothermia group was significantly reduced (both P<0.01); compared with the model group, the three intervention groups showed significant inhibition of miRNA-204 expression in brain tissues (all P<0.05), which was most significant in the acupuncture plus mild hypothermia group (P<0.01); compared with the acupuncture group and the mild hypothermia group, the Map3k8 expression in the acupuncture plus mild hypothermia group was significantly increased (both P<0.01), but there were no significant differences in Ntrk2 and Ppp3r1 expressions between groups (all P>0.05). Conclusion: Acupuncture, mild hypothermia, and acupuncture plus mild hypothermia reduced the neurological impairment score and the cerebral infarction area in CIRI rats, while acupuncture plus mild hypothermia showed the most significant effect. In regulating miRNA-204 target gene expressions, acupuncture plus mild hypothermia showed the same effect on Ntrk2 and Ppp3r1 expressions, while better effect on Map3k8 expression compared with either acupuncture or hypothermia.

Objective: We aimed to investigate and interpret the associations between socioeconomic factors and the prevalence, awareness, treatment, and control of hypertension at the provincial level in China. Methods: A nationally and provincially representative sample of 179,059 adults from the China Chronic Disease and Nutrition Surveillance study in 2015-2016 was used to estimate hypertension burden. The spatial Durbin error model was fitted to investigate socioeconomic factors associated with hypertension indicators. Results: Overall, it was estimated that 29.20% of the participants were hypertensive nationwide, among whom, 34.32% were aware of their condition, 27.69% had received antihypertensive treatment, and 7.81% had controlled their condition. Per capita gross domestic product (GDP) was associated with hypertension prevalence (coefficient: -2.95, 95% Conclusion Hypertension indicators were not only directly influenced by socioeconomic factors of local area but also indirectly affected by characteristics of geographical neighbors. Population-level strategies should involve optimizing supportive socioeconomic environment by integrating clinical care and public health services to decrease hypertension burden.
