Due to the diverse composition and complex physicochemical and biological characteristics, the pre-treatment of microbiological counting method （preparation of test solution） in microbiological limit test were interfered by many factors, which ultimately affected the repeatability and accuracy of test results. Improving the accuracy of microbiological test is of practical significance to ensure the safety and effectiveness of non-sterile preparations. In this paper, the key factors and optimization methods involved in the pre-treatment of proprietary Chinese medicines were systematically analyzed and summarized.

Background::Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods::We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018).Results::Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted β = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted β = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring’s overall crystallized intelligence. Conclusions::Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.

Objective:To translate the Wound Symptom Self-Assessment Chart (WoSSAC) into Chinese and test its reliability and validity among patients with malignant wounds in China.Methods:With authorization from the original author, the WoSSAC was translated into Chinese following Brislin's back-translation model, resulting in the Chinese version of WoSSAC. Convenience sampling was used to select 115 oncology patients with malignant wounds who were admitted to Beijing Cancer Hospital from June and December 2022 for a survey to validate the Chinese version of WoSSAC. Item analysis was used for item screening; content validity index and structural validity were used to test the validity of the scale. Reliability was assessed using Cronbach's α coefficient, split-half reliability, and test-retest reliability.Results:All 115 distributed questionnaires were completed and returned, yielding a 100% response rate. The Chinese version of WoSSAC consisted of 21 items divided into two parts: the severity of wound-related problems and the degree of impact on daily life. Exploratory factor analysis revealed two common factors from the section on the severity of wound-related problems, with a cumulative variance contribution rate of 83.583%, and two common factors from the section on the degree of impact on dailly life, with a cumulative variance contribution rate of 81.422%. The content validity index was 0.98 at the scale level and ranged from 0.80 to 1.00 at the item level. The Cronbach's α coefficient for the the section on the severity of wound-related problems was 0.979, with a split-half reliability of 0.924; for the section on the degree of impact on dailly life, Cronbach's α was 0.975, with a split-half reliability of 0.937. The test-retest reliability coefficients were 0.842 for the severity of wound-related problems and 0.903 for the degree of impact on daily life.Conclusions:The Chinese version of WoSSAC demonstrates good reliability and validity and can be used for self-assessment of the severity of malignant wound symptoms and their impact on daily life.

Objective:To compare the aortic remodeling of the Fabulous stent system and standard thoracic aortic endovascular repair (TEVAR) on distal aorta type B aortic dissection (TBAD). Methods:The prospective data collected between Dec 2017 and Oct 2019 from 134 patients with type B aortic dissection (TBAD) who underwent treatment with the "Fabulous" stent system, and retrospective data from 159 TBAD patients receiving standard TEVAR from corresponding multicenter. By using propensity score matching analysis, we compared the prognosis and aortic remodeling outcomes in patients undergoing Fabulous and standard TEVAR treatments during a 1-year postoperative follow-up.Results:In this study, 62 patients in Fabulous group and 62 patients in standard TEVAR were included.There were no significant statistical differences in baseline characteristics between the two groups. In terms of aortic remodeling in bare stent region, Fabulous group had better change trends of diameter of true lumen [10.6 (4.4, 14.5) mm vs. 4.7 (0.9, 10.7) mm, P=0.001] and false lumen [-24.2 (-30.5, -4.9) mm vs. 0.7 (-11.8, 2.3) mm, P<0.001] than those in the standard TEVAR group. The rate of complete false lumen thrombosis was also higher in the Fabulous group (62.9% vs. 37.1%, P=0.042). Conclusion:The Fabulous stent system, when compared to standard TEVAR surgery, demonstrates good aortic remodeling outcomes in the distal aorta.

Objective:To understand the out-of-hospital pain control situation, the medical compliance behavior of taking analgesics and status quo of constipation of patients with cancer pain and their correlations, so as to provide basis for the formulation of targeted continuous nursing measures.Methods:The trained full-time nurses in the pain clinic of the hospital conducted the telephone follow-up of cancer pain patients discharged from Peking University Cancer Hospital from July 2020 to October 2021 to understand the pain related information of patients at home, including the basic pain intensity in the past 24 hours, the compliance behavior of taking analgesics and the occurrence of constipation. The χ 2 test was used to analyze the relationship between pain intensity, medical compliance behavior and constipation. Results:A total of 1 013 patients with out-of-hospital cancer pain aged (61.30±12.56) years from 26 provinces, municipalities or autonomous regions in 6 geographical regions were investigated. 749 (73.94%) patients with cancer pain had moderate or severe pain, 357 patients (35.24%) complained that they did not fully follow the doctor's advice to take analgesic drugs and 533 patients (52.62%) had constipation. The pain intensity of patients with different medical compliance behaviors was different, and the proportion of moderate and severe pain in patients who did not fully follow medical instructions was higher, and the difference was statistically significant ( P<0.01). The pain intensity of patients with constipation was different from that of patients without constipation. The proportion of patients with moderate to severe pain was higher in patients with constipation, and the difference was statistically significant ( P<0.01) . Conclusions:Out-of-hospital cancer patients have poor pain control, some cancer pain patients do not follow the doctor's advice, and the incidence of constipation is high. The pain intensity of the patients is related to the compliance behavior of taking analgesics and constipation.

Lateral epicondylitis is a common clinical disease with characteristics of lateral elbow pain, insidious onset and easy recurrence, which can cause forearm pain and decreased wrist strength, seriously affecting patients′ daily life and work. Although there are various treatment methods for lateral epicondylitis with different effects, standard treatments are still lacking nowadays. Platelet-rich plasma (PRP) has good effects on bone and tendon repair, and is now widely used in the treatment of lateral epicondylitis. However, there is a lack of a unified understanding of the technology and specifications of PRP in the treatment of lateral epicondylitis. Therefore, the Sports Medicine Branch of the Chinese Medical Association and Physical Medicine and Rehabilitation Branch of the Chinese Medical Association organized experts in the fields of sports medicine and rehabilitation medicine in China to formulate the "clinical expert consensus on platelet-rich plasma treatment for lateral epicondylitis (2022 version)", and proposed suggestions based on evidence-based medicine mainly from the concept, epidemiology and pathophysiology of lateral epicondylitis, symptoms, signs and imaging manifestations of lateral epicondylitis, PRP concept and application component requirements, quality control of PRP preparation technology, indications and contraindications of PRP in the treatment of lateral epicondylitis, PRP injection in the treatment of lateral epicondylitis, application of PRP in the operation of lateral epicondylitis, related problems after PRP treatment of lateral epicondylitis, evaluation of the results after PRP treatment of lateral epicondylitis, and health and economic evaluation of PRP treatment of lateral epicondylitis, so as to provide guidance for clinical diagnosis and treatment.

Transcriptional regulators (TRs) participate in essential processes in cancer pathogenesis and are critical therapeutic targets. Identification of drug response-related TRs from cell line-based compound screening data is often challenging due to low mRNA abundance of TRs, protein modifications, and other confounders (CFs). In this study, we developed a regression-based pharmacogenomic and ChIP-seq data integration method (RePhine) to infer the impact of TRs on drug response through integrative analyses of pharmacogenomic and ChIP-seq data. RePhine was evaluated in simulation and pharmacogenomic data and was applied to pan-cancer datasets with the goal of biological discovery. In simulation data with added noises or CFs and in pharmacogenomic data, RePhine demonstrated an improved performance in comparison with three commonly used methods (including Pearson correlation analysis, logistic regression model, and gene set enrichment analysis). Utilizing RePhine and Cancer Cell Line Encyclopedia data, we observed that RePhine-derived TR signatures could effectively cluster drugs with different mechanisms of action. RePhine predicted that loss-of-function of EZH2/PRC2 reduces cancer cell sensitivity toward the BRAF inhibitor PLX4720. Experimental validation confirmed that pharmacological EZH2 inhibition increases the resistance of cancer cells to PLX4720 treatment. Our results support that RePhine is a useful tool for inferring drug response-related TRs and for potential therapeutic applications.

Objective To evaluate whether the thalamic paraventricular nucleus mediates orexiner-gic ( orexin ) neurons-induced promotion of emergence from general anesthesia by using the optogenetics method in mice. Methods Twenty healthy male Hcrt-cre mice, aged 8-10 weeks, weighing 20-25 g, were divided into 4 groups ( n=5 each) using a random number table method: retrograde labeled viruses channelrhodopsin group ( R group) , anterograde labeled viruses channelrhodopsin group ( A group) , retro-grade labeled viruses control group ( RC group ) , and anterograde labeled viruses control group ( AC group) . The optogenetics technique was used in each group. Anesthesia was induced and maintained through inhaling 1％ isoflurane and pure oxygen 1. 0 L∕min. Electroencephalogram was monitored througout the procedure with the PowerLab monitoring system. The burst suppression ratio ( BSR) was recorded at 1 min before light stimulation and during light stimulation. Results Compared with RC group or the baseline at 1 min before light stimulation, the BSR was significantly decreased during light stimulation in R group ( P<0. 05) . Compared with AC group or the baseline at 1 min before light stimulation, the BSR was signifi-cantly decreased during light stimulation in group A ( P<0. 05) . Conclusion Optogenetics technique ap-plication once again confirms that orexin neurons can promote emergence from general anesthesia through thalamic paraventricular nucleus in mice.

BACKGROUNDDiabetes-related pathogenic factors can cause retinal ganglion cell (RGC) apoptosis, but the specific mechanism is not very clear. The aim of this study is to investigate the correlation between glycogen synthase kinase-3 (GSK-3) activation and retinal neuron apoptosis.

METHODSIn an in vitro experiment, the number of apoptotic RGC-5 cells differentiated by staurosporine was evaluated via flow cytometry and nuclei staining using Hoechst 33258. GSK-3 phosphorylation and caspase-3 activation in RGC-5 cells after serum deprivation were determined using Western blotting. Mitochondrial membrane potential was detected using the dye 5, 5', 6, 6'tetrachloro-1, 1', 3, 3'-tetrethyl benzimidalyl carbocyanine iodide, and reactive oxygen species (ROS) levels were measured with dihydroethidium. In an in vivo experiment, the number of apoptotic retinal neurons was evaluated via terminal transferase dUTP nick-end labeling (TUNEL), and GSK-3 phosphorylation was determined using Western blotting, in the retinal nerve epithelial tissue of rats in which diabetes was induced by intravenous tail-vein injection of streptozotocin for 4 weeks.

RESULTSThe levels of phosphorylated Ser21/9 in GSK-3α/β and p-T308/S473-AKT were lower and the cleaved caspase-3 levels were higher in the serum-deprived model (P < 0.05). Lithium chloride treatment was associated with a slower rate of apoptosis, increased mitochondrial membrane potential, and decreased ROS levels in differentiated RGC-5 cells (P < 0.05). The level of blood glucose and the number of TUNEL-positive cells in the whole-mounted retinas were higher (P < 0.01), and the levels of phosphorylated Ser21/9 in GSK-3α/β and body weight were lower (P < 0.05). However, the thickness of the retinal nerve epithelial layer was not significantly less in diabetic rats compared with control group. Lithium chloride intravitreal injection increased the levels of phosphorylated Ser21/9 in GSK-3α/β and decreased TUNEL-positive cells in the whole-mounted retinas.

CONCLUSIONGSK-3 kinase is closely related to retinal neuron apoptosis, and the application of the GSK-3 inhibitor lithium chloride can reduce retinal neuron apoptosis in early diabetic retinopathy.
