Objective To analyze the characteristics of weekend surgery,and explore to shorten the preoperative hospital stay and average hospital stay of patients.Method Extract actual data on the number of discharged surgical patients and length of hospital stay,and use the Questionnaire Star to investigate the recognition of weekend surgeries by medical staff.Using chi square test and independent sample rank sum test,compare the differences in patients and surgical characteristics between weekend surgery and non weekend surgery,and analyze the influencing factors of surgical physicians using binary logistic regression model.Result The median length of hospital stay(3.0 days)and preoperative hospital stay(0.5 days)was lower than that of non weekend surgery patients(5.0,1.5 days);The proportion of fourth grade surgeries on weekends(28.9％)was lower than that of non weekend surgeries(37.0％);The consultation rate(10.74％)was lower than that of non weekend surgeries(17.0％);The proportion of daytime pilot surgeries(30.7％)was higher than that of non weekend surgeries(20.4％).The factors with the highest recognition among medical staff for conducting weekend surgeries were:improving patient satisfaction(84.7％)and reducing preoperative waiting risks(84.4％).The lowest factors were family support(45.5％)and multi departmental assistance and cooperation(58.8％).Conclusion Weekend surgery effectively shortens the average preoperative and average hospitalization days.Move the hospitalization consultation required for comorbidities management and preoperative examinations to the outpatient department.Mobilize the coordination and supporting resources of various departments within the hospital,and organically integrate various surgical methods such as weekend surgery and day surgery to improve the efficiency of medical operation.

Objective:To investigate the predictive value of transabdominal uterine electromyography for pre-term labor after tocolysis in women with threatened preterm labor.Methods:A total of 48 pregnant women at 28-34 weeks of gestation diagnosed with threatened preterm labor and admitted to The Fourth Affiliated Hospital of Soo-chow University from January to September 2023 were included.According to the response to tocolysis and whether the pregnancy was prolonged for at least 48 h,women were divided into two groups:non-preterm birth within 48 h(n=35)and preterm birth within 48 h(n=13).Uterine electromyography parameters and difference were compared before and after tocolytic therapy in two groups.Univariate Logistic regression was performed to predict the related factors of preterm birth within 48 h after the using of tocolysis in pregnant women with threat-ened preterm birth by uterine electromyography,and receiver operating characteristic(ROC)curve was per-formed to evaluate their performance.Results:Compared to before treatment with tocolysis,after therapy,in the non-preterm birth within 48 h group,significant reductions in contraction frequency,area,duration and amplitude were observed(P<0.05).In the preterm birth within 48 h group,only contraction frequency decreased significant-ly(P<0.05).Univariate Logistic regression indicated that contraction frequency,contraction duration,and contrac-tion area were predictive factors for premature birth within 48 h after tocolysis(P<0.05).When the duration of u-terine contractions lasting for 104.55 s or more the sensitivity and specificity of predicting premature birth within 48 h are 92.3％and 68.6％,respectively.Conclusions:Uterine electromyography may predict the premature birth within 48 h after tocolytic treatment in preterm labor,which may provide reference for subsequent corticosteroid therapy or transfer of high-risk pregnant patients.

Antibody-drug conjugates (ADCs) combine the high specificity of monoclonal antibodies with the high anti-tumor activity of small molecular cytotoxic payloads. The anti-tumor activity of ADCs is mainly achieved by the direct blocking of the receptor by monoclonal antibodies, direct action and bystander effect of cytotoxic drugs, and antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity. ADCs have been used in adjuvant therapy and rescue treatment of human epidermal receptor 2 (HER2)-positive breast cancer, greatly improving the prognosis of breast cancer patients. Several ongoing clinical trials of ADC for breast cancer and other solid tumors proved the potential of ADCs will provide more promising treatment options for patients with malignant tumors. This review introduces the mechanism and latest clinical progress of ADC drugs approved for HER2-positive breast cancer to guide clinical practice and conduct research.

Objective:To explore the relationship between mild cognition impairment(MCI) and components of metabolic syndrome in the elderly.Methods:A total of 293 patients aged 65 years and older with an average age of (78.8 ± 7.5) years who met the inclusion criteria were included.The Montreal Cognitive Assessment Scale(MoCA)was used to evaluate cognitive function.The components of the metabolic syndrome were compared between the MCI and the normal cognitive function(NC) groups.Binary Logistic regression analysis was used to analyze the relationship between cognitive function and components of the metabolic syndrome.Results:The levels of body mass index(BMI)and tryglicerides(TG)were lower in the MCI group than in the NC group[BMI, (22.9±3.7)kg/m 2vs.(25.3±3.3)kg/m 2, t=3.124, P=0.002; TG, 1.2±0.6 mmol/L vs. 1.4±0.7 mmol/L, t=2.615, P=0.009]. The differences in proportions of hypertension and diabetes and in levels of fasting blood glucose and high-density lipoprotein cholesterol had no statistically significance between the MCI group and the NC group(all P>0.05). Binary multivariate Logistic regression analysis showed that after adjusting for age and education, BMI was independently associated with MCI, and as BMI increased, the risk of MCI decreased( OR=0.901, 95% CI: 0.838-0.968, P=0.004). In elderly men, after adjusting for age, education level and smoking history, TG was independently associated with MCI, and as TG increased, the risk of MCI decreased( OR=0.446, 95% CI: 0.249-0.874, P=0.017). While in elderly women, no independent correlation between TG and MCI was observed. Conclusions:BMI is independently associated with MCI.Screening for cognitive function among low-level BMI elderly is helpful to identify MCI.The relationship between TG and MCI is different between different genders, and different standards might be adopted for the management of TG in elderly MCI patients with different genders.

Bone graft is an important basic condition for repairing skull defect caused by various reasons,but whether autologous bone graft or allograft bone transplantation,the clinical limitations was increasingly significant.With the development of bone tissue engineering,the introduction of bone progenitor cells and growth factors into composite scaffolds made from natural or synthetic materials,and as a substitute for bone graft has become a hot spot of research.It will review the research progress on bone graft substitute and bone biomimetic scaffold material,so as to provides reference on the further investigations.

Objective Parkinson's disease (PD) is a common degenerative disease of the central nervous system.The main pathological feature is the reduction of dopaminergic neurons,which induces motion symptoms such as resting tremor,muscle rigidity,bradykinesia,and postural disorder.The etiology and pathogenesis of PD are complex and related to a variety of factors.The current pathogenesis is related to mitochondrial dysfunction,oxidative stress,neuroinflammatory response,apoptosis,and autophagy.The early onset of PD is occult and the rate of misdiagnosis is high.It requires a new simple,safe,and effective early diagnosis method.The current methods of early diagnosis mainly include clinical non-motor symptoms,biomarkers,and imaging examination methods.

Objective To study the effects of abiotic elicitors methyl jasmonate (MeJA) and salicylic acid (SA) on the alkaloids accumulation and related enzymes metabolism inPinellia ternata suspension cell cultures. Methods Using the leaf petioles-derived suspension cell cultures as the study object, the culture duration, concentrations of MeJA and SA were determined to get the optimal alkaloids accumulation, and the activities of metabolic enzymes IMP dehydrogenase and sAMP synthase were also measured.Results A 9-fold of dried biomass and a 3-fold of alkaloids accumulation were observed inP. ternata suspension cell cultures after culture for 21 d. Both MeJA and SA could significantly promote the accumulation of alkaloids inP. ternata suspension cells. 150 μmol/L MeJA enhanced alkaloids content (4.7 mg/gDW) by 3.6 folds in comparison with control group, whereas 50 μmol/L SA showed a 2.5-fold increase. Meanwhile, 100 μmol/L MeJA and 50 μmol/L SA promoted the increase in IMP dehydrogenase activity by 3.0 and 3.7 fold respectively, and 150 μmol/L MeJA and 100 μmol/L SA showed the increase by 2.6 and 4.4 fold respectively.Conclusion Proper adding exogenous MeJA and SA can promote the accumulation of alkaloids inPinellia ternata suspension cell cultures.
