Neonatal sepsis is a global health problem that seriously affects the body health and life safety of newborns. It has a higher incidence in preterm infants,especially for early-onset sepsis (EOS) within 72 hours of birth. The diagnosis of neonatal EOS requires a series of examinations,and early and accurate diagnosis can improve clinical outcomes and reduce antibiotic overuse in a timely manner. At present,the commonly used biomarkers and traditional blood culture methods for EOS diagnosis have certain shortcomings,so it is urgent to find new molecular diagnostic methods. This article summarizes and compares the early and novel diagnostic methods of neonatal EOS,in order to provide a reference for clinical practice.

Acute lung injury(ALI) is a critical clinical condition primarily characterized by refractory hypoxemia and infiltration of inflammatory cells in lung tissue, which can progress into a more severe form known as acute respiratory distress syndrome(ARDS). Immune cells and inflammatory cytokines play important roles in the progression of the disease. Due to its unclear pathogenesis and the lack of effective clinical treatments, ALI is associated with a high mortality rate and severely affects patients' quality of life, making the search for effective therapeutic agents particularly urgent. Ginseng Radix et Rhizoma, the dried root of the perennial herb Panax ginseng from the Araliaceae family, contains active ingredients such as saponins and polysaccharides, which possess various pharmacological effects including anti-tumor activity, immune regulation, and metabolic modulation. In recent years, studies have shown that ginsenosides exhibit notable effects in reducing inflammation, ameliorating epithelial and endothelial cell injury, and providing anticoagulant action, indicating their comprehensive role in alleviating lung injury. This review summarizes the pathogenesis of ALI and the molecular mechanisms through which ginsenosides act at different stages of ALI development. The aim is to provide a scientific reference for the development of ginsenoside-based drugs targeting ALI, as well as a theoretical basis for the clinical application of Ginseng Radix et Rhizoma in the treatment of ALI.

italic>Platycodon grandiflorum (Jacq.) A. DC is one of the most commonly used bulk medicinal herbs. It has important value in the fields of medicine, food and cosmetics, and its market demand is increasing year by year, and it has a good development prospect. In this study, based on 403 distribution records and 8 environmental variables, we used Maxent model to predict the potential distribution of P. grandiflorum under climate change. The results showed that the model simulation effect was the best when the Maxent parameter was FC (feature combination) = LQPH (L: linear features; Q: quadratic features; P: product features; H: hinge features) and RM (regularization multiplier) = 2.1, AUC (area under curve) = 0.901, and the model prediction showed that P. grandiflorum was widely distributed in 28 provinces of China under the current climate conditions, with a suitable area of 2 337 419.98 km². Under the influence of climate change in the future, the area of suitable habitat of P. grandiflorum showed a decreasing trend, and the distribution center as a whole showed a trend of northward and eastward shift. The distribution area of P. grandiflorum in the three main producing areas is affected by climate change, and the overall trend is that the future suitable distribution area of Chifeng in Inner Mongolia increases, while the future suitable distribution area of Zibo in Shandong and Taihe, Bozhou in Anhui decreases or even disappears under the SSP5-8.5 scenario (shared socioeconomic pathways). It is suggested to maintain and protect the ecological environment and germplasm resources of the reserved area suitable for the growth of P. grandiflorum, and increase the cultivation research in the expansion area of P. grandiflorum, so as to lay a foundation for the subsequent expansion of P. grandiflorum planting and to promote the protection and sustainable development of P. grandiflorum resources.

An integrated evaluation model based on the combination of traditional trait identification and modern chemical analysis was used for the identification of key indexes of grade classification and the establishment of grade quality standard of Lycium barbarum fruits (LBF) from Ningxia genuine producing area. Under the guidance of herbal examination and market survey, particle size, skin color and imperfection were taken as the external trait indicators; focusing on the comprehensiveness and validity of the quality evaluation, 2-O-β-D-glucopyranosyl-L-ascorbic acid (AA-2βG), zeaxanthin dipalmitate (ZD) and volatile ether extractives were used as important parameters involving in quality evaluation in addition to the pharmacopoeia test items and determination indicators such as moisture, ash, water-soluble extractives, Lycium barbarum polysaccharide (LBP) and betaine. The quality differences between different traits and grades of LBF as well as the relevance between character and quality were further investigated by mathematical and statistical means such as t-test analysis, correlation analysis and principal component analysis (PCA). Furthermore, the activities of extractives from different grades of LBF were compared at cellular level. The results showed that LBF were mainly preferred for large and red ones; except for betaine, the other index components were relatively high (moisture and ash were low) in the first-grade and samples with bright-red skin color. Besides, there was a significant correlation between skin color and moisture, water-soluble extractives, LBP, AA-2βG and ZD contents. Considering the results of the study and the market situation, the present study took the grain size and skin color of LBF as the core of evaluation, and at the same time introduced the multi-indicator components including LBP, AA-2βG, ZD, water-soluble extractives and moisture to further guide the grading, and established the quality standard of LBF grades combining the trait indexes and the chemical composition. More importantly, in vitro cell models both preliminarily confirmed that the first-grade LBF played a more significant "nourishing liver and kidney" effect, which provided an experimental basis for the quality control of LBF and promoted the realization of high quality and good price.

Osteoporosis is an important cause of internal fixation loosening after spinal surgery.Cement-augmented pedicle screw instru-mentation(CAPSI)technique is the most widely used technique in clinical practice to improve the stability of pedicle screw,mainly applied in osteoporosis and revision surgery,which included conventional solid pedicles crews and fenestrated/cannulated pedicle screws technique.CAPSI technique may cause cement leakage and pulmonary embolism,and there is no consensus on its indications or technical points.Therefore,this article reviews the research progress of CAPSI,in order to provide relevant reference for clinical practice.

OBJECTIVE: To evaluate the feasibility and tolerability of metoprolol standard dosing pathway (MSDP) in Chinese patients with acute coronary syndrome (ACS). METHODS: In this multicenter, prospective, open label, single-arm and interventional study that was conducted from February 2018 to April 2019 in fifteen Chinese hospitals. A total of 998 hospitalized patients aged ≥ 18 years and diagnosed with ACS were included. The MSDP was applied to all eligible ACS patients based on the standard treatment recommended by international guidelines. The primary endpoint was the percentage of patients achieving the target dose at discharge (V2). The secondary endpoints included the heart rate and blood pressure at V2 and four weeks after discharge (V4), and percentage of patients experiencing bradycardia (heart rate < 50 beats/min), hypotension (blood pressure < 90/60 mmHg) and transient cardiac dysfunction at V2 and V4. RESULTS: Of the 998 patients, 29.46% of patients achieved the target dose (≥ 95 mg/d) at V2. The total population was divided into two groups: target group (patients achieving the target dose at V2) and non-target group (patients not achieving the target dose at V2). There was significant difference in the reduction of heart rate from baseline to discharge in the two groups (-4.97 ± 11.90 beats/min vs. -2.70 ± 9.47 beats/min, P = 0.034). There was no significant difference in the proportion of bradycardia that occurred in the two groups at V2 (0 vs. 0, P = 1.000) and V4 (0.81% vs. 0.33%, P = 0.715). There was no significant difference in the proportion of hypotension between the two groups at V2 (0.004% vs. 0.004%, P = 1.000) and V4 (0 vs. 0.005%, P = 0.560). No transient cardiac dysfunction occurred in two groups during the study. A total of five adverse events (1.70%) and one serious adverse event (0.34%) were related to the pathway in target group. CONCLUSIONS In Chinese ACS patients, the feasibility and tolerability of the MSDP have been proved to be acceptable.

Objective To understand the body characteristics of adults from the Tibeto-Burman language group. Methods Totally 14 837 adults (6578 males and 8259 females) from 17 minorities were selected for investigation during 2015 to 2019 and these surveys were carried out in regions including Sichuan, Yunnan, Guizhou, Hubei, Hunan and Tibet Autonomous Region. Eight physical parameters (stature, sitting height, etc.) along with 4 corresponding indexes (stature-sitting index and the like) were carefully analyzed. The body characteristics of the Tibeto-Burman language group were then compared to those of certain minorities as well as Han in both northern and southern part of China based on our collected data. Results Among 17 minorities of the Tibeto-Burman language group, people from Pumi and Tibet were relatively tall and have longer trunk and limbs. The presence of wider trunk and thicker limbs appeared to be common in Tibetan individuals. Subjects from Lahu, Jino and Derung were in possession of shorter stature and limbs while the trunk of Naxi, Lisu and Achang people seemed wider. Compared with other ethnic groups in China, individuals from the Tibeto-Burman language group tended to own shorter stature accompanied by medium trunk width, probably sharing similar physical characteristics with those minorities in southern China, especially She and Li. Conclusion Among ethnic groups dotting in southern China, individuals from the Tibeto-Burman language group generally have medium stature, medium trunk height, and wide trunk whereas those from 3 Mon-Khmer groups, Va, Khmus and Blang, are shorter and smaller in width and height of the trunk.

OBJECTIVE: To compare the clinical efficacy and possible mechanism of warming acupuncture combined with "three steps and seven methods" of tuina and simple "three steps and seven methods" of tuina in treatment of chronic nonspecific low back pain (NLBP) of yang deficiency and cold-dampness blockage. METHODS: A total of 138 patients were randomized into an observation group (69 cases, 5 cases dropped off) and a control group (69 cases, 7 cases dropped off). In the control group, "three steps and seven methods" of tuina was applied. On the basis of the treatment in the control group, warming acupuncture was applied at Shenshu (BL 23), Yaoyangguan (GV 3), Mingmen (GV 4), Weizhong (BL 40) and ashi points. The treatment was given once a day, 6 times a week for 3 weeks in both groups. Before and after treatment, the short form of McGill pain questionnaire (SF-MPQ) score, Oswestry disability index (ODI) score, finger-to-floor distance (FFD), Schober test distance, fear-avoidance beliefs questionnaire (FABQ) score and yang deficiency and cold-dampness blockage score were observed, the serum levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6 and thromboxane B₂ (TXB₂) were detected in both groups. The recurrence rate was evaluated in follow-up of 6 months after treatment. RESULTS: After treatment, the scores of PRI, PPI, VAS, ODI, FABQ and FFD, yang deficiency and cold-dampness blockage scores were decreased compared before treatment in both groups (P<0.01), and those in the observation group were lower than the control group (P<0.01); the Schober test distances were increased compared before treatment in both groups (P<0.01), and that in the observation group was larger than the control group (P<0.01). After treatment, the serum levels of TNF-α, IL-1β, IL-6 and TXB₂ were decreased compared before treatment in both groups (P<0.01), and those in the observation group were lower than the control group (P<0.01). In follow-up, the recurrence rate was 12.8% (6/47) in the observation group, which was lower than 34.3% (12/35) in the control group (P<0.05). CONCLUSION Warming acupuncture combined with "three steps and seven methods" of tuina can effectively alleviate pain in patients with chronic NLBP of yang deficiency and cold-dampness blockage, improve activity and dysfunction of waist, the clinical efficacy is superior to simple "three steps and seven methods" of tuina, its mechanism may be relate to the inhibition of inflammatory reaction.
