Surgery is usually the first choice for patients with lung cancer,whereas the risk increases with age.A comprehensive evaluation of the patients should be applied in order to bring about the best outcome.By convention,the preoperative assessment includes neoplasm staging,cardio-respiratory function assessment, nutritional status assessment,and etc. The surgical planning includes limited resection,video-assisted thoracoscopic surgery and so on.

Objective:To observe the effect of Ba Duan Jin(Eight-brocade Exercise)plus Tuina(Chinese therapeutic massage)in treating primary dysmenorrhea due to cold-induced blood stasis in female college students and on the score of fatigue scale-14(FS-14). Methods:Seventy-two female college students with primary dysmenorrhea due to cold-induced blood stasis were randomized into a Tuina group and a joint group,with 36 cases in each group.The Tuina group only received Tuina manipulations.In the joint group,besides the same Tuina manipulations,patients practiced Ba Duan Jin.For both groups,the once-daily intervention was conducted from 6 d before the menstrual period until menstrual day 1 for 3 menstrual cycles.Changes in the scores of COX menstrual symptom scale(CMSS),visual analog scale(VAS),and FS-14 after the intervention were observed.Clinical efficacy was also estimated. Results:During the process,1 case dropped out in the Tuina group,and 35 cases completed the intervention;2 cases dropped out in the joint group,and 34 cases completed the intervention.The total effective rate was 94.1%in the joint group,higher than 88.6%in the Tuina group(P<0.05).After treatment,the symptom duration and intensity scores in the scores of CMSS,VAS,and FS-14 declined in both groups(P<0.05 or P<0.01);the CMSS symptom duration score and FS-14 score were lower in the joint group than in the Tuina group(P<0.05). Conclusion:Tuina manipulations alone or combined with Ba Duan Jin practice can effectively treat primary dysmenorrhea due to cold-induced blood stasis in female college students;when combined with Ba Duan Jin practice,Tuina manipulations can more significantly improve pain duration and fatigue,suggesting the advantages of combining Tuina Gongfa and manipulations.

OBJECTIVE: To explore the genetic basis for a fetus with severe heart defect and mosaic trisomy 12, and the correlation between chromosomal abnormalities and clinical manifestations and pregnancy outcome. METHODS: A 33-year-old pregnant woman who presented at Lianyungang Maternal and Child Health Care Hospital on May 17, 2021 due to abnormal fetal heart development revealed by ultrasonography was selected as the study subject. Clinical data of the fetus were collected. Amniotic fluid sample of the pregnant women was collected and subjected to G-banded chromosomal karyotyping and chromosomal microarray analysis (CMA). The CNKI, WanFang and PubMed databases were searched with key words, with the retrieval period set as from June 1, 1992 to June 1, 2022. RESULTS: For the 33-year-old pregnant woman, ultrasonography at 22+6 gestational weeks had revealed abnormal fetal heart development and ectopic pulmonary vein drainage. G-banded karyotyping showed that the fetus has a karyotype of mos 47,XX,+12[1]/46,XX[73], with the mosaicism rate being 1.35%. CMA results suggested that about 18% of fetal chromosome 12 was trisomic. A newborn was delivered at 39 weeks of gestation. Follow-up confirmed severe congenital heart disease, small head circumference, low-set ears and auricular deformity. The infant had died 3 months later. The database search has retrieved 9 reports. Literature review suggested that the liveborn infants with mosaic trisomy 12 had diverse clinical manifestations depending on the affected organs, which had included congenital heart disease and/or other organs and facial dysmorphisms, resulting in adverse pregnancy outcomes. CONCLUSION Trisomy 12 mosaicism is an important factor for severe heart defects. The results of ultrasound examination have important value for evaluating the prognosis of the affected fetuses.

ObjectiveTo observe the mechanism of modified Shengjiangsan in necroptosis and renal fibrosis of rats with diabetic nephropathy based on receptor-interacting protein （RIP）1/RIP3/mixed lineage kinase domain-like protein （MLKL） signaling pathway. MethodSeventy-five SD rats were randomly divided into a model group， a normal group， three high， medium， and low-dose modified Shengjiangsan groups （4.365， 8.73， 17.46 g·kg^-1）， and an irbesartan group （0.013 5 g·kg^-1）. After 4 weeks of intragastric administration， the levels of 24 h urine protein （UTP）， tumor necrosis factor-α （TNF-α）， and interleukin-1β （IL-1β） of rats in each group were determined， as well as the changes in degree of renal pathology. Real-time quantitative polymerase chain reaction （Real-time PCR） and immunohistochemistry were used to detect the mRNA and protein expression levels of IL-1β， TNF-α， monocyte chemoattractant protein-1 （MCP-1）， transforming growth factor-β₁ （TGF-β₁）， and nuclear factor kappa B （NF-κB） in kidney tissues of rats. Western blot assay was used to detect the expression levels of key proteins in the RIP1/RIP3/MLKL signaling pathway. ResultAs compared with the normal group， the renal interstitial fibrosis in the model group was obvious， and the 24 h UTP， IL-1β， TNF-α levels were significantly increased （P<0.05）. In the model group， the mRNA and protein expression levels of IL-1β， TNF-α， MCP -1， TGF-β₁， and NF-κB in the kidney tissues were significantly increased （P<0.05）， and protein expression levels of RIP1， RIP3， p-MLKL， and MLKL were significantly increased （P<0.05）. Compared with the model group， all modified Shengjiangsan groups and the irbesartan group improved the levels of renal interstitial fibrosis in rats to varying degrees. As compared with the model group， the 24 h UTP levels in all modified Shengjiangsan groups and the irbesartan group were decreased to varying degrees （P<0.05）， the content of IL-1β and TNF-α in the serum were decreased （P<0.05）， the mRNA and protein expression levels of IL-1β， TNF-α， MCP-1， TGF-β₁， and NF-κB in renal tissues was down-regulated （P<0.05）， and the protein expression levels of RIP1， RIP3， p-MLKL， and MLKL were down-regulated （P<0.05）. ConclusionModified Shengjiangsan ameliorates renal injury of rats with diabetic nephropathy， and the mechanism may be related to the down-regulation of the RIP1/RIP3/MLKL signaling pathway， the prevention of renal tissue necroptosis， and the inhibition of renal fibrosis.

Laccases are enzymes belonging to the group of multi-copper oxidases. These enzymes are widely distributed in insects, plants, fungi and bacteria. In general, laccases can oxidize an exceptionally high number of substrates, so they have broad applications in textile, pulp, food and the degradation of lignin. However, low yield, low activity and thermo-instability of laccase in nature limit the application of laccase. High efficient heterologous expression of the protein is an effective way for solving this problem. Here, we summarize the research advances of heterologous expression of eukaryote-origin laccases. We focus on the overexpression of eukaryote-origin laccases using different expression system and the method for improving the production yield and enzyme activity in yeast cells. Information provided in this review would be helpful for researchers in the field.

Background::Liver cancer remains the sixth most commonly diagnosed cancer and the third leading cause of cancer-related deaths worldwide, causing a heavy burden globally. An updated assessment of the global epidemiology of the liver cancer burden that addresses geographical disparities is necessary to better understand and promote healthcare delivery.Methods::Data were extracted from the GLOBOCAN 2022 database, including the number, crude, and age-standardized rates of incidence and mortality at the global, country, continent, and human development index (HDI) regional levels. Age-standardized rates (incidence and mortality) per 100,000 person-years were adjusted based on the Segi-Doll World standard population. The mortality-to-incidence ratios (MIR) for each region and country were calculated. The HDI and gross national income (GNI) for 2022 were obtained, and a Pearson correlation analysis was conducted with the incidence, mortality, and MIR.Results::In 2022, approximately 866,136 new liver cancer cases and 758,725 related deaths were recorded worldwide, with a global MIR of 0.86. Males had a disproportionately higher burden than females across all levels, and the highest burden was observed in the elderly population. Geographically, the regions with the highest incidence rates included Micronesia, Eastern Asia, and Northern Africa, and the regions with the highest mortality rates included Northern Africa, Southeastern Asia, Eastern Asia, and Micronesia. Notably, Mongolia had a strikingly high burden compared to other countries. The highest MIR was observed in North America and the lowest in Africa. Negative associations of HDI and GNI with liver cancer mortality and MIR were identified, irrespective of sex.Conclusions::The current liver cancer burden underscores the presence of remarkable geographic heterogeneity, which is particularly evident across countries with varying HDI levels, highlighting the urgent need to prioritize health accessibility and availability to achieve health inequities.

Objective To observe the effect of Baduanjin exercise on depression,sleep quality and life quality of patients with breast cancer in the rehabilitation period.Methods A total of 76 breast can-cer patients in postoperative rehabilitation were randomly divided into an intervention group of 38 with 2 dropping out,and a control group of 38 with 3 dropouts.Both groups received routine nursing and rehabilitation after breast cancer surgery,while the intervention group additionally practised Baduanjin for 6 weeks.The Beck Depression Inventory-Ⅱ(BDI-Ⅱ-C),Pittsburgh Sleep Quality Index(PSQI)and Quality of Life Questionnaire Core 30(EORTC QLQ-C30)were used to evaluate both groups be-fore,as well as 3 and 6 weeks after intervention.Results After 3-week intervention,the average BDI-Ⅱ-C score,the total PSQI score and the scores of all dimensions except for the hypnotic drug dimen-sion of the intervention group was significantly lower than before treatment(P<0.05),and the control group at the same time point(P<0.05),while the scores of physical,emotional,cognitive,social and role function in EORTC QLQ-C30 were significantly higher than the latter(P<0.05).Three weeks lat-er,the average BDI-Ⅱ-C score,the total PSQI score and the scores of all dimensions except for the hypnotic drug dimension of the intervention group was significantly lower than before treatment(P<0.05),and the control group at the same time point(P<0.05),while the various scores of EORTC QLQ-C30 were significantly higher than the latter(P<0.05).Compared with after 3-week intervention,after 6-week intervention,the average BDI-Ⅱ-C score,the total PSQI score and the scores of its all dimensions except for the sleep disorder dimension of the intervention group decreased significantly,while all dimension scores of EORTC QLQ-C30 except the cognitive function dimension increased sig-nificantly(P<0.05 for all).Conclusion Baduanjin is feasible in improving the sleep and life quality of patients in the rehabilitation period after breast cancer surgery,and relieving their depression.

Integration results 3: hospital fall prevention measures and evaluation from the perspective of inpatients. Integration result 4: inpatients expected to receive care from their families and help from medical staff. Conclusion Fall events seriously affect the mental health of patients; Patients′ cognition of falling is affected and changed by many factors. Fall prevention should shift from clinical focus to patient-centered and attach importance to the participation of family members.

Purpose: This study aims to comprehensively evaluate the clinical efficacy of chemotherapy or endocrine therapy maintenance in metastatic breast cancer (MBC) patients. Materials and Methods: The meta-analysis of randomized clinical trials (RCTs) and propensity score matching of multicenter cohort study evaluated MBC patients who underwent first-line chemotherapy or endocrine therapy maintenance. This study is registered with PROSPERO: CRD42017071858 and ClinicalTrials.gov: NCT04258163. Results: A total of 2,867 patients from 15 RCTs and 760 patients from multicenter cohort were included. The results from meta-analysis showed that chemotherapy maintenance improved progression-free survival (PFS) (hazard ratio [HR], 0.63; 95% confidence interval [CI], 0.54 to 0.73; p < 0.001; moderate-quality evidence) and overall survival (OS) (HR, 0.87; 95% CI 0.78 to 0.97; p=0.016; high-quality evidence) than observation. In the cohort study, for hormone receptor–positive MBC patients, chemotherapy maintenance improved PFS (HR, 0.67; 95% CI, 0.52 to 0.85; p < 0.001) and OS (HR, 0.55; 95% CI 0.42 to 0.73; p < 0.001) compared with observation, and endocrine therapy maintenance also improved PFS (HR, 0.65; 95% CI, 0.53 to 0.80; p < 0.001) and OS (HR, 0.55; 95% CI, 0.44 to 0.69; p < 0.001). There were no differences between chemotherapy and endocrine therapy maintenance in PFS and OS (all p > 0.05). Regardless of the continuum or switch maintenance therapy, showed prolonged survival in MBC patients who were response to first-line treatment. Conclusion This study provided evidences for survival benefits of chemotherapy and endocrine therapy maintenance in MBC patients, and there was no difference efficacy between chemotherapy and endocrine therapy maintenance for hormone receptor–positive patients.

Objective : To investigate the effect and mechanism of Src homology 2 domain - containing protein tyrosine phosphatase inhibitor PHPS1 on atherosclerotic plaque vulnerability in ApoE knockout mice , and to provide a new idea for the study of atherosclerosis. Methods : Sixteen 8 ⁃week⁃old ApoE - / - mice were randomly divided into control group and PHPS1 group. The aortic root was fixed with formalin and sectioned. The collagen and macrophage contents in the plaque were evaluated by Movat and Sirius red staining. The activity of ERK and the expression of MMP⁃9 in the descending aorta were detected by Western blot. Results : The plaque area (0. 52 ± 0. 05) , (0. 31 ± 0. 03 ) , collagen content (0. 062 ± 0. 013 ) , (0. 136 ± 0. 022) and macrophage cell ratio (0. 799 ± 0. 031) , (0. 621 ± 0. 043) were different between PHPS1 group and control group ( P < 0. 01) . The results of western blot showed that PHPS1 inhibited the activity of ERK and decreased the protein expression of MMP⁃9 (P <0. 01) . Conclusion PHPS 1 , an inhibitor of SHP⁃2 , can inhibit ERK activity and decrease the expression of MMP⁃9 , thus reducing the degradation of collagen in fibrous cap and stabilizing vulnerable atherosclerotic plaque.
