Objective To analyze the risk factors affecting liver regeneration after laparoscopic anatomic liver resection(LALR),and to explore the relationship between postoperative liver regeneration and the prognosis of patients.Methods A retrospective analysis was conducted on the clinical data of 156 patients with liver cancer who underwent LALR treatment at the People's Hospital Affiliated to Shandong First Medical University from January 2021 to December 2023.Three-dimensional liver reconstruction and simulated resection were performed based on CT examination,and the postoperative liver regeneration rate was calculated.The patients were divided into the high regeneration group and the low regeneration group based on the median liver regeneration rate 1 month after surgery,and the univariate and multivariate analyses were performed to analyze the risk factors affecting postoperative liver regeneration.The relationships between post-operative liver regeneration capacity and tumor-free survival rate and overall survival rate of patients were analyzed using the Kaplan-Meier survival curve.Results Significant difference was observed between the future remnant liver volume(FRLV)1 week after operation and the remnant liver volume(RLV)after operation(P<0.05).The liver regeneration rates 1 month and 3 months after operation were significantly higher than that 1 week after operation(P<0.05).The net growth rate of liver volume 1 week after operation was significantly higher than that 1 month and 3 months after operation(P<0.05).The median liver regeneration rate 1 month after operation was 27.81%.Univariate analysis showed that gender,age,drinking history,combined with liver cirrhosis,preoperative predictional RLV,preoperative predictional standard residual liver volume(SRLV),and postoperative platelet count(PLT)were closely related to liver regeneration after operation(P<0.05).Multivariate analysis showed that combined with liver cirrhosis,and high preoperative predictional RLV and SRLV were the independent factors affecting liver regeneration after operation(P<0.05).The postoperative follow-up showed that the cumulative tumor-free survival rate of the high regeneration group was lower than that of the low regeneration group(61.20%vs.75.28%,Log-rank χ2=3.577,P=0.043),and there was no statistically significant difference in the cumulative overall survival rate between the two groups(74.63%vs.80.89%,Log-rank χ2=1.024,P=0.312).Conclusion For patients with liver cancer undergoing LALR,combined with liver cirrhosis,and high preoperative predictional RLV and SRLV are the independent risk factors influencing early postoperative liver regeneration.Moreover,the higher the patients' postoperative liver regeneration capacity,the lower the tumor-free survival rate.

Objective To explore the impact of different delay time of umbilical cord ligation on the outcome of preterm infants.Methods A total of 266 preterm infants born in the obstetric department of this hospital from January 2021 to December 2022 were selected as the research subjects and divided into the in-stant group(umbilical cord ligation immediately after birth,n=53),30 s group(delayed umbilical cord liga-tion for 30 s,n=50),60 s group(delayed umbilical cord ligation for 60 s,n=55),90 s group(delayed umbili-cal cord ligation for 90 s,n=55)and 120 s group(delayed umbilical cord ligation for 120 s,n=52)according to the random number table method.The Hb and HCT levels and the incidence rates of anemia,blood transfu-sion,hyperbilirubinemia,intracranial hemorrhage,necrotizing enterocolitis(NEC)and bronchopulmonary dys-plasia(BPD)after birth were compared among 5 groups.Results The Hb and HCT levels at 24 h after birth in the 60,90,120 s groups were higher than those in the instant group and 30 s group,moreover the 120 s group was higher than the 60 s group and 90 s group,and the differences were statistically significant(P＜0.05).The anemia incidence rate and blood transfusion rate in the 60,90,120 s groups were lower than those in the instant group and 30 s group,and the differences were statistically significant(P＜0.05).The hyperbil-irubinemia incidence rate in the 120 s group was higher than that in the other 4 groups,and the difference was statistically significant(P＜0.05).The intracranial hemorrhage incidence rate in the 60,90,120 s groups were lower than those in the instant group and 30 s group,and the differences were statistically significant(P＜0.05).The NEC incidence rate in the 60 s and 90 s group was lower than that in the instant group and 30 s group,but the 120 s group was higher than that in the other 4 groups,and the differences were statistically significant(P＜0.05).The BPD incidence rate had no statistical difference among 5 groups(P＞0.05).Con-clusion Delayed umbilical cord ligation for 60 s or 90 s could improve the outcomes of preterm infants.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

BACKGROUND:Medical hydrogels are new functional polymer materials with three-dimensional structural networks and excellent biocompatibility,which have been widely studied in the field of tissue engineering and drug carriers,but the research on the combination of medical hydrogels and Chinese medicine for the treatment of diseases based on tissue engineering is still in the early exploration stage.Therefore,through the analysis of the mechanism of the role of medical hydrogels,the integration of medical hydrogels and Chinese medicine in the research of the joint application of the article,can better provide ideas for scientific researchers,and the joint application of Chinese medicine and medical hydrogels is of great significance. OBJECTIVE:To explore the strategy and significance of Chinese medicine combined with medical hydrogel for disease treatment based on tissue engineering research. METHODS:PubMed and CNKI were used to retrieve articles about the application of Chinese medicine combined with medical hydrogel in tissue engineering from January 2010 to November 2022,with the Chinese and English search terms"hydrogel,traditional Chinese medicine,drug carrier,tissue engineering".After the initial screening of all articles according to the inclusion and exclusion criteria,the 61 articles with high relevance were retained for review. RESULTS AND CONCLUSION:(1)Although the application of Chinese medicine combined with medical hydrogel is involved in intra-articular,intra-tissue organ,soft tissue wounds,tissue engineering,etc.,except for the clinical application of Chinese medicine combined with hydrogel dressing for soft tissue injury,other aspects are still in the experimental stage.(2)The development of Chinese medicine combined with medical hydrogel has great potential and development prospects,but there is a certain difficulty in the manufacture of the gel with high-performance requirements,and it is difficult to master the physical and chemical properties precisely.(3)At present,the comprehensive view of injectable hydrogel with the characteristics of easy to use,its joint use of Chinese medicine can be extended to a wider range,can be used for joint,organ,tissue engineering-related disease treatment.Smart hydrogel has high sensitivity and reversible transformation can also meet the use of the special environment.During the combined use of Chinese medicine,it also needs to understand the mechanism of action of Chinese medicine components.(4)The strategy of combining Chinese medicine with medical hydrogels for disease treatment should start with matching the therapeutic effects of Chinese medicine on organs,tissues and cells combined with appropriate types of medical hydrogels to make up for the shortcomings of traditional Chinese medicine delivery methods and frequent drug delivery.In tissue engineering,hydrogels can be loaded with stem cells after Chinese medicine intervention,or with both Chinese medicine and stem cells for disease treatment.(5)In future research of combined Chinese medicine and medical hydrogel application,we also need to consider:we should ensure that the biological properties of medical hydrogel can be quantified,and grasp the characteristics of hydrogel with different manufacturing processes of different materials to produce the required medical hydrogel that meets the application conditions.In Chinese medicine,we need to comprehensively understand and analyze the therapeutic effects and application mechanisms of known Chinese medicine monomer and Chinese medicine compound extracts,so as to achieve a more perfect combination between Chinese medicine and medical hydrogel under a more clear mechanism.With the continuous improvement of medical science and technology innovation,the medical hydrogel can be innovatively combined with other traditional treatment methods of Chinese medicine,such as acupuncture,massage,cupping and so on,to be used from multiple angles.

OBJECTIVE: This study assesses the impact of iodine-rich processed foods and dining places on the iodine nutritional status of children. METHODS: School-aged children (SAC) in seven provinces in China were selected by school-based multi-stage sampling. Urinary iodine, salt iodine, and thyroid volume (TVOL) were determined. Questionnaires were used to investigate dining places and iodine-rich processed foods. The water iodine was from the 2017 national survey. Multi-factor regression analysis was used to find correlations between variables. RESULTS: Children ate 78.7% of their meals at home, 15.1% at school canteens, and 6.1% at other places. The percentage of daily iodine intake from water, iodized salt, iodine-rich processed foods, and cooked food were 1.0%, 79.2%, 1.5%, and 18.4%, respectively. The salt iodine was correlated with the urinary iodine and TVOL, respectively (r = 0.999 and -0.997, P < 0.05). The iodine intake in processed foods was weakly correlated with the TVOL (r = 0.080, P < 0.01). Non-iodized salt used in processed foods or diets when eating out had less effect on children's iodine nutrition status. CONCLUSION Iodized salt remains the primary source of daily iodine intake of SAC, and processed food has less effect on iodine nutrition. Therefore, for children, iodized salt should be a compulsory supplement in their routine diet.

The purpose of this study was to explore the clinical efficacy and safety of Gynostemma pentaphyllum (G. pentaphyllum) in the treatment of hyperlipidemia, and to provide systematic evaluation basis for clinical application. CNKI, Wanfang Data, VIP, Web of science, PubMed, Embase and Cochrane Library were searched for randomized controlled trials (RCTs) about G. pentaphyllum in the treatment of hyperlipidemia. Review Manager 5.4 were used for statistical analysis. Through reading topics, abstracts, and full texts, 27 papers with 2311 cases involved that met the inclusion and exclusion criteria were finally included for the analysis. In terms of curative effect, the effect of G. pentaphyllum alone in increasing high density lipoprotein (HDL) index was better than that of conventional treatment, and the effect of reducing total cholesterol (TC), triglyceride (TG) and low density lipoprotein (LDL) was similar to that of conventional treatment. There was a synergistic effect between G. pentaphyllum and conventional drugs, and the combination of G. pentaphyllum and conventional drugs was superior to conventional treatment in reducing TG and increasing HDL. G. pentaphyllum can also decrease the levels of serum glutamic pyruvic transaminase and glutamic oxaloacetic transaminase in the treatment of hyperlipidemia, indicating a certain protective function of the liver. In terms of safety, there were fewer cases of adverse reactions in the G. pentaphyllum treatment group, and the adverse reaction events reported in the literature was mild. According to the results of meta-analysis, G. pentaphyllum was effective in the treatment of hyperlipidemia, and it has the potential to be combined with traditional drugs, has a certain liver protection function, and was superior to traditional drugs in the treatment of hyperlipidemia.

OBJECTIVE: This study aimed to assess the associations between maternal drug use, cytochrome P450 ( CYP450) genetic polymorphisms, and their interactions with the risk of congenital heart defects (CHDs) in offspring. METHODS: A case-control study involving 569 mothers of CHD cases and 652 controls was conducted from November 2017 to January 2020. RESULTS: After adjusting for potential confounding factors, the results show that mothers who used ovulatory drugs (adjusted odds ratio [a OR] = 2.12; 95% confidence interval [ CI]: 1.08-4.16), antidepressants (a OR = 2.56; 95% CI: 1.36-4.82), antiabortifacients (a OR = 1.55; 95% CI: 1.00-2.40), or traditional Chinese drugs (a OR = 1.97; 95% CI: 1.26-3.09) during pregnancy were at a significantly higher risk of CHDs in offspring. Maternal CYP450 genetic polymorphisms at rs1065852 (A/T vs. A/A: OR = 1.53, 95% CI: 1.10-2.14; T/T vs. A/A: OR = 1.57, 95% CI: 1.07-2.31) and rs16947 (G/G vs. C/C: OR = 3.41, 95% CI: 1.82-6.39) were also significantly associated with the risk of CHDs in offspring. Additionally, significant interactions were observed between the CYP450genetic variants and drug use on the development of CHDs. CONCLUSIONS In those of Chinese descent, ovulatory drugs, antidepressants, antiabortifacients, and traditional Chinese medicines may be associated with the risk of CHDs in offspring. Maternal CYP450 genes may regulate the effects of maternal drug exposure on fetal heart development.
