Objective To explore the effects of single rectangle cage interbody fusion combined with pedicle screw fixa?tion for isthmic spondylolisthesis. Methods Data of the 34 cases with isthmic spondylolisthesis hospitalized at our department from March 2012 to February 2015 were retrospectively analyzed. All cases were operated by posterior pedicle screw fixation com?bined with single rectangle cage interbody fusion. There were 21 males and 13 females, aging from 18 to 63 years old (with an aver?age age of 41.6±8.2 years). Lesion segments were L4 in 15 cases and L5 in 19 cases;there were 12 cases in Meyerding I degree, 16 in II degree and 6 in III degree;28 patients had lower back pain associated with lower limb pain;19 patients had lower back pain associated with numbness of lower limb;18 patients had lower back pain associated with lower limb muscle weakness and 2 pa?tients had urination and defecation function disturbance. The surgical operation time, bleeding, postoperative drainage flow, graft fusion rate, complications were measured, and the intervertebral disc height, Japanese Orthopaedic Association (JOA), Oswestry disability indes (ODI), visual analogue scale (VAS) score were compared before and after treatment. Results The operation of 34 patients was successfully completed with the average operation time of 1.8 ± 0.8 h, and the bleeding in operation was 362.4 ± 93.7 ml, while postoperative drainage flow was 116.3±54.2 ml. All patients were effectively followed up for 12 months to 46 months (av?erage, one year and 10 months). Two weeks after operation, the intervertebral disc height were obviously increased (9.85±1.11 mm, 9.63 ± 1.04 mm), and there were significant difference compared with preoperative results (6.53 ± 0.98 mm, 6.24 ± 1.07 mm), but there were no significant difference compared with the latest follow?up results (9.23±1.33 mm, 9.30±1.16 mm). At the latest follow?up, JOA score was 13.19±1.08, ODI score 12.34±7.52, VAS score 2.23±1.51, and there were significantly different in each score compared with preoperative results. The symptoms of low back pain, lower limb nerve dysfunction and quality of life were signifi?cantly improved compared with preoperative situation. At the 16 month follow?up, all postoperative patients with vertebral body bone graft were judged to be fused. There was no pedicle screw loosening, fracture and so on. Conclusion Single rectangle cage interbody fusion combined with pedicle screw fixation for the treatment of isthmic spondylolisthesis is a kind of mini?invasive, less bleeding, safe and effective surgical method.

OBJECTIVETo investigate action of hydrophilic constituents from Coptidis Rhizoma on glucose-lowering effect metabolism of berberine in HepG2 cells.
METHODHydrophilic fractions of Coptidis Rhizoma were prepared by high speed counter current chromatography and separated by silica gel column chromatography. MTT assay was used to monitor the proliferation of HepG2 cells, and Kit was used to test the glucose consumption in culture solution.
RESULTCholine was separated from Coptidis Rhizoma for the first time. Cell assay showed choline can significantly increase the glucose lowering effect of berberine and improve the cytotoxicity of berberine within test concentration. Compared with same dose of berberine, berberine 38 mg x L(-1) in combination with choline 100 mg x L(-1) can make glucose consumption increase by 34% and elevate cell livability up to 75% in HepG2 cells.
CONCLUSIONThe results suggest that choline had a synergistic effect on improving glucose absorption of berberine and decreasing cytotoxicity of berberine.

Alzheimer's disease (AD) is the most common form of dementia in the elderly, and there is no specific treatment to stop or reverse its progression. Mild cognitive impairment (MCI) is an important entry point for early diagnosis and prevention of AD. More and more studies have explored the risk factors and biomarkers for conversion from MCI to AD, and a series of risk prediction models have been established. This article analyzes and summarizes the different predictors and risk prediction models so as to provide basis for early identifying the high-risk group of AD, managing the controllable risk factors, and providing references for the selection and improvement of these models.

BackgroundElderly cataract patients with depressive symptoms have heavier self-perceived burden, and worse vision-related quality of life compared to patients without depressive symptoms, resulting in the increase of family burden. Most previous studies showed that family relationship and vision were the main factors leading to depression in elderly cataract patients, and ignored the effects of self-feeling and complicated diseases on the psychological state of elderly cataract patients. ObjectiveTo explore the relationship between depressive symptoms, self-perceived burden and postoperative vision-related quality of life in elderly cataract patients, and to analyze the risk factors of depressive symptoms. So as to provide references for targeted psychological intervention in this population. MethodsA total of 104 elderly cataract patients admitted to Jiangsu Province Hospital (The First Affiliated Hospital with Nanjing Medical University) from July 1, 2020 to December 31, 2022 were included. General information, self-perceived burden and postoperative vision-related quality of life were investigated by self-designed questionnaire, Patients' Health Questionnaire depressive Scale-9 item (PHQ-9), Self-Perceived Burden Scale (SPBS) and National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25). Pearson correlation analysis was performed to analyze the correlation among PHQ-9, SPBS and NEI-VFQ-25 scores. Logistic regression analysis was used to analyze the influencing factors of depressive symptoms in eldery cataract patients. ResultsA total of 100 elderly cataract patients completed an effective questionnaire survey. Among the participants, 31 cases (31.00%) were found to have depressive symptoms. The depressive group exhibited significantly higher SPBS score (t=11.062, P<0.01) and significantly lower NEI-VFQ-25 score (t=-5.235, P<0.01) than those of the non-depressive group. Pearson correlation analysis showed a positive correlation between PHQ-9 and SPBS score (r=0.485, P<0.01), and a negative correlation between PHQ-9 and NEI-VFQ-25 score (r=-0.440, P<0.01). Complicated with diabetes (OR=1.441, P<0.01), osteoarthritis (OR=1.324, P<0.05) and high SPBS score (OR=1.340, P<0.05) were risk factors of depressive sympptoms in elderly cataract patients. ConclusionThe detection rate of depressive symptoms in elderly cataract patients is higher, and postoperative vision-related quality of life in elderly cataract patients complicated with depressive symptoms is poor. Risk factors include diabetes, osteoarthritis and high self-perceived burden. [Funded by 2022 Jiangsu Province Elderly Health Scientific Research Project (number, LKM2022019)]
