The STAR tool was used to evaluate and analyze the science, transparency, and applicability of Chinese pathology guidelines and consensus published in medical journals in 2022. There were a total of 18 pathology guidelines and consensuses published in 2022, including 1 guideline and 17 consensuses. The results showed that the guideline score was 21.83 points, lower than the overall guideline average (43.4 points). Consensus ratings scored an average of 27.87 points, on par with the overall consensus level (28.3 points). Areas that scored above the overall level were "conflict of interest" and "working groups", while areas that scored below the overall level were "proposals", "funding", "evidence", "consensus approaches" and "accessibility". To sum up, the formulation of pathology guidelines and consensuses in 2022 is not standardized, and the evidence retrieval process, evidence evaluation methods and grading criteria for recommendations on clinical issues are not provided in the formulation process; the process and method for reaching consensus are not provided, the plan is lacking, and registration is not carried out. It is therefore suggested that guidelines/consensus makers in the field of pathology should attach importance to evidence-based medical evidence, strictly follow guideline formulation methods and processes, further improve the scientific, applicable and transparent guidelines/consensuses in the field, and better provide support for clinicians and patients.

Objective:To analyze the nutritional status of elderly inpatients using Global Leadership Initiative on Malnutrition (GLIM) criteria.Methods:A total of 5 236 elderly patients (aged 65 years or older) who were hospitalized at the West China Hospital, Sichuan University from March 2021 to March 2022 were included. The nutritional status was analyzed using the GLIM diagnostic criteria for malnutrition.Results:The rate of patients at nutritional risk was 30.29%, and the incidence of malnutrition as per GLIM criteria was 15.64%. The levels of hemoglobin, albumin, triglycerides, and cholesterol, and body mass index of the malnutrition group were lower compared with the non-malnutrition group, and the differences were statistically significant ( P<0.05). The non-malnutrition group had significantly shorter hospital stay and lower hospitalization costs compared with the malnutrition group ( P<0.001). Conclusions:The GLIM criteria is suitable for evaluating the nutritional status in elderly inpatients. The incidence of malnutrition in elderly inpatients is relatively high, which deserves attention in clinical management.

Objective To investigate the median effective dose (ED₅₀) and 95% effective dose (ED₉₅) of ciprofol in combination with butorphanol for painless gastroscopy in elderly patients. Methods A total of 27 elderly patients with selective gastroscopy were conducted with intravenous induction of 5 μg/kg butorphanol for at least 30 seconds, and 3 minutes later, they were administered intravenously with ciprofol for at least 30 seconds; gastroscopy was performed when the eyelash reflex disappeared or the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) score was less than one point. The initial dose of ciprofol was set as 0.2 mg/kg, and the modified sequential allocation method was used; if there was a positive response during the insertion of the gastroscope, the dose for the next patient would increase by one level, and vice versa, the dose would decrease by one level, with an adjacent dose concentration gradient of 0.05 mg/kg. A positive response to gastroscope insertion was defined as coughing, swallowing, or limb movements when the gastroscope entered the throat. The study was terminated after 7 reversals in ciprofol dose adjustments. ED₅₀, ED₉₅, and corresponding 95% confidence intervals (95%CI) of ciprofol combined with butorphanol for painless gastroscopy were calculated. Results When combined with butorphanol, the ED₅₀ of ciprofol for painless gastroscopy in elderly patients was 0.253 mg/kg (95%CI, 0.219 to 0.290), and the ED₉₅ was 0.328 mg/kg (95%CI, 0.290 to 0.521). Conclusion When combined with butorphanol, the ED₅₀ of ciprofol for painless gastroscopy in elderly patients is 0.253 mg/kg, and the ED₉₅ is 0.328 mg/kg.

Objective:To explore the long-term preservation value and repair effect of normothermic machine perfusion (NMP) on clinically discarded kidneys.Methods:A case of clinical discarded donor kidney was collected, and NMP was carried out in vitro for 9 hours with recovered blood. The dynamic changes of renal appearance, blood gas and biochemistry analysis of perfusate and renal pathology were recorded. Results:In the second to fifth hour of NMP, the appearance of renal was pink and ex vivo normothermic perfusion assessment score (EVNP) was grade Ⅰ. While, the sixth hour and beyond of NMP, the appearance of kidney turned to dark red and EVNP was grade Ⅲ. The renal perfusion blood flow maintained above 150 ml/min in the first 6 hours and decreased significantly after that, and at the end, was only 50 ml/min. During the whole process of perfusion, urine output was maintained at about 100 ml/h. PO 2 remained above 100 mmHg in the first 5 hours of perfusion and from the 6th hour, was lower than 80 mmHg and continued to decline, and was close to 0 at the end of perfusion. The results showed that although the K + concentration changes in blood and urine in the first 5 hours of NMP had a good consistency, the lactic acid level had been rising. In addition, there was no significant change in the histopathology at the fourth hour of perfusion compared with that before zero-point puncture, and the fibrinous thrombus in glomeruli was improved compared with that before perfusion. However, at the sixth hour after perfusion and before the end of perfusion, the pathological changes of renal tissue were significantly worse. There were a large of thrombosis in glomerular blood vessels, renal tubular atrophy and acute tubular necrosis. Conclusions:NMP can realize the evaluation of extended criteria donors before transplantation, and it proves the feasibility and repair potential of NMP in kidney to a certain extent. At the same time, NMP also provides a new way to expand the source of donor kidney and to pre-treat organ in vitro.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

The progress of epigenetic research has led to the discovery and confirmation of age-related markers based on DNA methylation. These DNA methylation indices are called "epigenetic clock/age". The concept of "epigenetic clock/age" and the establishment of its evaluation system are helpful to solve some of the long-standing problems in the field of life and medicine. When facing the current global aging, it is of great significance to refer to the comprehensive health parameters to determine the biological age and life span of an individual, and thus to design a plan to slow down the process of life cycle. This paper has summarized the concept and development of "epigenetic clock/age" in recent years.

Objective:To investigate the clinical significance of LncRNA anti-differetiation non-coding RNA (ANCR) expression in tumor tissues of gastric cancer patients and its biological effects on cells.Methods:72 cases of gastric cancer tissues and corresponding adjacent tissues were collected from Sep. 2016 to Jun. 2018 in our Hospital. Gastric cancer cell HGC-27 was cultured, lentiviral transfected ANCR cDNA full-length vector was used as a Test group in HGC-27 cells, and transfected blank vector as a control group. Real-time quantitative PCR (qPCR) was used to detect the expression of ANCR, transcription factor Oct4 and Sox2 mRNA in tissues or cells, Western blot was used to detect the expression levels of Oct4 and Sox2 in cells, CCK-8 assay was employed for detecting cell proliferation in both groups, and Transwell invasion and migration assay was used to detect the transfer ability of cells in the two groups.Results:The expressions of ANCR in gastric cancer and corresponding adjacent tissues were respectively 0.013 (0.006, 0.025) and 0.041 (0.011, 0.136) , and the expression of ANCR in gastric cancer tissues was significantly higher than that in adjacent tissues ( P<0.01) , and patients with high expression of ANCR had higher TNM stage and lower cell differentiation ( χ2=7.414 and 8.236, P<0.05) . The expressions of ANCR mRNA in control group and test group were respectively 1.000±0.064 and 6.250±0.889, Oct4 mRNA were respectively 1.000±0.208 and 2.815±0.349, Sox2 mRNA were respectively 1.000±0.173 and 2.526±0.390, Oct4 protein were respectively 1.000±0.148 and 3.396±0.105, Sox2 protein were respectively 1.000±0.119 and 2.916±0.130, and the expressions of ANCR, Oct4 and Sox2 mRNA in the test group were significantly higher than those in the control group ( P<0.01) ; the expression levels of Oct4 and Sox2 protein in the test group were significantly higher than those in the control group. The proliferation abilities of control group and test group were 7.164±0.426 and 9.627±0.605 in 72h, and 13.750±1.089 and 19.166±1.649 in 96h. The proliferation of cells in the Test group at 72 and 96 hours was significantly higher than that in the control group ( P<0.01) . The average number of invasive cells per visual field in control group and test group were 17.26±5.48 and 39.43±5.21, and number of migration cells were 30.49±7.74 and 62.20±7.51, and the number of migration and invasion cells in the Test group was significantly larger than that in the control group ( P<0.01) . Conclusions:The expression of LncRNA ANCR in tumor tissues of gastric cancer patients is significantly increased, and it is closely related to the progression of the disease of patients and the degree of cell malignancy. It can promote the expression of gastric cancer stem cell markers in vitro and enhance the ability of cell proliferation and metastasis.
