Objective:To investigate the clinical efficacy of lumbar lateral interbody fusion (LLIF) versus posterior lumbar interbody fusion (PLIF) in the treatment of severe lumbar spinal stenosis.Methods:The data of patients with severe lumbar spinal stenosis who underwent LLIF or PLIF from February 2019 to December 2023 were retrospectively analyzed. There were 30 patients in the LLIF group, 10 males and 20 females, aged 62.7±5.6 years (range, 53-74 years), including 21 cases of single segment and 9 cases of double segment. There were 46 patients in the PLIF group, including 20 males and 26 females, aged 63.2±8.4 years (range, 43-75 years), 40 cases of single segment and 6 cases of double segment. The visual analogue scale (VAS), Oswestry disability index (ODI), intervertebral space height, intervertebral foramen height and postoperative complications were compared between the two groups.Results:All patients were followed up for an average of 21.3±6.4 months (range, 12-32 months). The intraoperative blood loss in the LLIF group was 112.2±76.9 ml, which was significantly lower than 193.9±88.2 ml in the PLIF group ( P<0.05). The VAS scores of back pain and leg pain after operation were significantly lower than those before operation in the two groups ( P<0.05). There was no statistically significant difference between groups in back pain VAS scores at preoperative, 6 months postoperative, and final follow-up ( P>0.05); the back pain VAS score at 1 month postoperatively in the LLIF group was 1.6±1.2, which was less than 2.8±0.7 in the PLIF group ( P<0.05). There was no statistically significant difference between groups in leg pain VAS scores at preoperative, 1 month postoperative, and 6 months postoperative ( P>0.05); the leg pain VAS score at the final follow-up in the LLIF group was 1.2±1.5, which was smaller than 1.8±1.0 in the PLIF group ( P<0.05). The postoperative ODI was smaller than the preoperative one in both groups, and the difference was statistically significant ( P<0.05); the preoperative, 1-month postoperative, 6-month postoperative, and final follow-up ODIs in the LLIF group were 45.7%±16.0%, 17.9%±12.0%, 16.2%±11.6%, and 15.7%±11.7%, and those in the PLIF group were 47.9%±15.4%, 20.1%±9.3%, 16.9%±10.6%, and 14.6%±11.0% in the PLIF group, and the difference between the groups was not statistically significant ( P>0.05). The preoperative intervertebral space height in the LLIF group was 10.6±2.0 mm, which was smaller than that in the PLIF group 11.8±2.2 mm ( P<0.05). The intervertebral space heights in the immediate postoperative period and at the final follow-up were 13.3±2.3 mm and 12.3±2.2 mm in the LLIF group and 13.7±1.7 mm and 13.0±1.9 mm in the PLIF group ( P>0.05). The preoperative intervertebral foraminal height in the LLIF group was 18.0±3.2 mm, which was smaller than that of 19.7±2.4 mm in the PLIF group ( P<0.05); the intervertebral foraminal heights in the immediate postoperative period and at the final follow-up were 21.4±2.5 mm and 20.2±2.4 mm in the LLIF group, and in the PLIF group were 20.7±2.4 mm and 19.7±2.6 mm in the PLIF group ( P>0.05). In the LLIF group, 2 cases had femoral nerve injury and 2 cases had transient back pain after operation. There were 2 cases of cerebrospinal fluid leakage, 1 case of screw loosening, and 2 cases of deep vein thrombosis in the PLIF group. In the PLIF group, 2 patients underwent revision, including 1 case due to cage displacement and 1 case due to screw malposition. The fusion settling rate was 21% (8/39) in the LLIF group and 12% (6/52) in the PLIF group ( P>0.05). Conclusion:Both LLIF and PLIF can effectively restore the intervertebral height, improve the lumbar function and the symptoms of back and leg pain in the treatment of severe lumbar spinal stenosis.

Objective To explore the predictive value of the triglycerides/high-density lipoprotein cholesterol(TG/HDL-C)ratio com-bined with the mean platelet volume/platelet count(MPV/PC)ratio for in-stent restenosis(ISR)after percutaneous coronary intervention(PCI)in elderly patients with coronary heart disease.Methods A total of 240 elderly patients with coronary heart disease admitted at the Pingmei Shenma Medical Group General Hospital from January 2021 to January 2023 were selected and divided into the ISR(36 cases)and non-ISR(204 cases)groups based on whether ISR occurred 6 months after PCI.The clinical data,TG/HDL-C ratio,and MPV/PC ratio of the two groups were compared,and Pearson's correlation analysis was used to analyze the correlation between the TG/HDL-C and MPV/PC ratios.Multivariate logistic regression analysis was used to analyze the relationship between the TG/HDL-C ratio,MPV/PC ratio,and ISR after PCI.The receiver operating characteristic(ROC)curve and area under the curve(AUC)were used to evaluate the predictive value of the TG/HDL-C and MPV/PC ratios for ISR after PCI in older patients with coronary heart disease.Results There were statisti-cally significant differences in the comparisons of diabetes,hypertension,the degree of coronary artery stenosis,and stent diameter between the two groups(P<0.05);the ISR group had higher TG levels,MPV levels,TG/HDL-C ratios,and MPV/PC ratios,and lower HDL-C and PC levels compared to the non-ISR group(P<0.05);the TG/HDL-C ratio was positively correlated with the MPV/PC ratio(P<0.05);the TG/HDL-C and MPV/PC ratios were independently associated with ISR after PCI in older patients with coronary heart disease(P<0.05);and the AUC for predicting ISR after PCI in older patients with coronary heart disease was 0.759 and 0.784 for the TG/HDL-C and MPV/PC ratios,respectively,and the combined prediction showed an AUC of 0.921,which was superior to that of either alone.Conclusion The TG/HDL-C and MPV/PC ratios were significantly correlated with ISR in elderly patients with coronary heart disease after PCI,and their combined predictive value was reliable.

Objective To develop an inpatient assessment form for geriatric syndromes,aiming to quickly and accurately determine whether elderly inpatients are at risk of geriatric syndromes.Methods From May 2021 to December 2023,an initial item pool for the scale was proposed through literature review.Sixteen experts from four fields of geriatric nursing,nursing management,nursing education,and geriatric medicine were selected from seven institutions in six provinces and cities across the country.Two rounds of Delphi expert consultation were conducted to inquire about the assessment form.Results The enthusiasm coefficient of the two rounds of expert consultation was 100.00%,and the expert authority coefficient was 0.88.In the first round of expert consultation,the importance ratings of the three-level indicators ranged from 4.06 to 4.75,with a coefficient of variation of 0.09 to 0.25,a full score rate of 43.75%to 81.25%,and a Kendall coordination coefficient W of 0.210.In the second round of expert consultation,the importance ratings of the three-level indicators ranged from 4.63 to 4.94,with a coefficient of variation of 0.05 to 0.13,a full score rate of 62.50%to 93.75%,and a Kendall coordination coefficient W of 0.419.After two rounds of expert consultation,the inpatient assessment form for geriatric syndromes was finally determined,including 5 first-level indicators(past history,physical function,common geriatric symptoms,mental and psychological status,socioeconomic status),26 second-level indicators,and 41 third-level indicators.Conclusion The inpatient assessment form for geriatric syndromes developed in this study is scientifically and practically feasible and can be used to quickly identify the risk of geriatric syndromes in elderly inpatients.

Objective To examine the influence of hormonal fluctuations on the perioperative outcomes of patients undergoing congenital heart surgery. Methods We conducted a retrospective analysis of clinical data from fertile women diagnosed with congenital heart disease at the Guangdong Provincial People's Hospital, between January 1, 2015, and July 30, 2019. Initially, patients were categorized into groups based on serum progesterone levels: a low progesterone group (n=31) and a high progesterone group (n=153). Furthermore, based on serum estrogen levels, they were divided into a low estrogen group (n=10), a medium estrogen group (n=32), and a high estrogen group (n=118) for comparative analysis. A control group (n=24) consisted of patients who received progesterone injections before their menstrual period. Results We finally included 184 patients. The patients’ average age was 27.6±5.7 years, with 142 (77.17%) presenting with complex congenital heart conditions. There were statistically significant differences in total postoperative standard thoracic drainage volume and postoperative albumin level between the high and low progesterone groups (P<0.05), while other perioperative outcome indicators showed no statistical differences (P>0.05). Among the different serum estrogen level groups, there were statistically significant differences in postoperative blood urea nitrogen levels, total postoperative standard thoracic drainage volume, and hospital stay (P<0.05), while other perioperative outcome indicators showed no statistical differences (P>0.05). Conclusion Considering the overall clinical significance, the physiological changes in sex hormone levels appear to have a negligible effect on the perioperative outcomes of fertile women with congenital heart disease.

Objective:To investigate an accurate and quantitative method to measure the eyeball morphological parameters of guinea pigs through a method that combines programmed digital techniques and mathematical geometric principles.Methods:Twenty-two three-week-old clean-grade male tricolor guinea pigs were selected and sacrificed by anesthesia overdose.Eyeballs were enucleated.The horizontal and sagittal images of the eyeball were taken with the high-speed photographic model of 13 million pixels macro meter, and the pictures were imported into pycharm programming software.Using the pre-written analysis program of Python 3.9, the conversion coefficient between the photo pixel and the actual length was obtained by a scale, and then the corneal surface was fitted by arc fitting and conic curve fitting.The results of arc fitting were converted to calculate the corneal radius of curvature.The corneal eccentricity was calculated according to the general conic equation (Ax 2+ Bxy+ Cy 2+ Dx+ Ey+ F=0). The corneal asphericity was evaluated by curve fitting between the central 3-mm and the whole cornea.The use and care of the animals complied with Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.The study protocol was approved by the Ethics Committee of Shanghai Public Health Clinical Center (No.2022-A009-01). Results:The digital method of Python programming can show the corneal contour of guinea pigs completely and clearly.In the transverse plane, there was no significant difference in the corneal curvature measurements among the digital fitting in central 3-mm cornea, digital fitting in whole cornea and curvature meter ( F=1.693, P=0.190). In the sagittal plane, there was a significant difference in the corneal curvature measurements among the three methods ( F=3.500, P=0.030), and the corneal curvature measurements of the whole cornea measured by the curvature meter were significantly greater than those measured by the digital fitting ( P<0.05). There was no statistical significance in the measurements of corneal curvature radius among the three methods in the transverse plane and the sagittal plane ( F=1.817, P=0.170; F=2.050, P=0.133). The horizontal and sagittal corneal eccentricity measured by digital fitting in central 3-mm cornea were 0.55±0.15 and 0.53±0.17, which were lower than 0.66±0.10 and 0.64±0.14 measured by digital fitting in whole cornea, and the differences were statistically significant ( t=-4.860, -5.210; both at P<0.01). Conclusions:It is feasible to use Python programming digital method to measure the corneal curvature and eccentricity of guinea pigs.

ObjectiveTo investigate effect of astragaloside Ⅳ on the proliferation， migration， and invasion of colorectal cancer HCT116 cells and the underlying molecular mechanism. MethodColorectal cancer HCT116 cells were classified into blank group （DMSO） and low-dose （15.7 mg·L^-1）， medium-dose （31.4 mg·L^-1）， and high-dose （62.8 mg·L^-1） astragaloside Ⅳ groups. After drug treatment， the morphological changes of HCT116 cells were observed under an inverted microscope. Cell viability was detected by cell counting kit-8 （CCK-8） assay， and the migration and invasion of cells were detected based on scratch assay and Transwell assay. The expression of cyclin-dependent kinase inhibitor （p21）， CyclinD₁， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in the cells was examined by Western blot. ResultCompared with the blank group， cells in the three astragaloside Ⅳ groups demonstrated slow growth， low density， inconsistent morphology， nuclear shrinkage， degradation of cytoplasm， and high death rate. Moreover， cell viability decreased in a concentration-dependent manner in the astragaloside Ⅳ groups. Cell migration and invasion were inhibited （P<0.05， P<0.01）， and the inhibition rate was in positive correlation with the concentration of the astragaloside Ⅳ. The expression of pro-apoptotic protein Bax in low-dose， medium-dose and high-dose astragaloside Ⅳ groups increased gradually in a concentration-dependent manner， while the expression of p21， CyclinD₁ and anti-apoptotic protein Bcl-2 decreased gradually in a concentration-dependent manner compared with those in the blank group （P<0.05， P<0.01）. ConclusionAstragaloside Ⅳ can suppress the proliferation， migration， and invasion of colorectal cancer HCT116 cells and promote the apoptosis， thus inhibiting the occurrence and development of colorectal cancer.
