Objective To study the effects of glucose and lipid metabolism on gallstone formation. Methods Twenty five patients with gallstones and 25 normal volunteer controls were studied from January to April in 1998. The patients were well matched the control with sex and age (1∶1). In the study, Body Mass Index (BMI) and Waist-to-Hip circumference ratio (W/H) were measured. Blood glucose, glucosylated hemoglobin (HbA1C), insulin, C peptide and all parameters of lipids were detected at fasting state. The glucose,insulin, C peptide were detected again at 2-hour after taking 75g glucose orally.Results The result showed there was no difference on BMI and W/H between the patients and controls. HbA1C、mean fasting and 2hour glucose concentration were not in significantly different between the two groups (Pgt;0.05, Pgt;0.2, Pgt;0.1 respectively). There were 10 patients with abnormal glucose metabolism (7 with NIDDM, 3 with IGT), but only 4 controls were abnoumal (one with NIDDM, three with IGT). The difference was significant (Plt;0.05). Furthermore, the mean fasting and 2hour insulin concentration of gallstone group was higher than that of the control (Plt;0.02, Plt;0.05). And the gallstone group had a higher fasting C peptide concentration than control (Plt;0.05). There was no statistical difference on the parameters of plasma lipid between the tow groups. Conclusion The study suggests that diabetes mellious and hyperinsulinemia acted as an important role on gallstone formation.
Objective To systematically evaluate the effect of arm sling on shoulder subluxation in stroke patients with hemiplegia. METHODS CNKI, Wanfang, VIP, PubMed, Web of Science, Embase, Cochrane Library, OVID, EBM Reviews, Best Practice, ACP Journal Club, and Practice Guidline were searched from establishment to March 2023. The literature on randomized controlled trials of arm sling on gait or balance in post-stroke patients with hemiplegia were included. RevMan 5.4.1 software was used for meta-analysis. Results A total of 13 articles were included, including 691 subjects, 343 in the experimental group, and 348 in the control group. The meta-analysis results showed that patients wearing the boom arm were effective in improving the recovery of upper extremity function [mean difference (MD)=8.12, 95% confidence interval (CI) (2.39, 11.60), P＜0.000 01], relieving pain due to shoulder subluxation [MD=−1.13, 95%CI (−1.70, −0.56), P=0.000 1], and enhancement of patients’ quality of life in daily activities [MD=15.07, 95%CI (3.24, 26.90), P=0.01], all of which were superior to the control group. However, there was no statistically significant difference between the two groups in terms of Apnea-Hypopnea Index [MD=−1.86, 95%CI (−3.79, 0.06), P=0.06], 6 min walking test [MD=−0.51, 95%CI (−18.52, 17.49), P=0.96], 10 meter walk time [MD=0.00, 95%CI (−0.06, 0.06), P=0.91], heart rate [MD=−0.22, 95%CI (−5.10, 4.27), P=0.93], and Berg balance scale [MD=−2.53, 95%CI (−8.17, 3.10), P=0.38]. Conclusion The use of arm sling can effectively improve patients’ quality of life, functional recovery of the upper limbs and reduce pain, providing an evidence-based basis for healthcare professionals to treat patients with proven treatment modalities.
Objective To investigate perindopiI influence for the complication in hypertensive patients with stroke history by lowering blood pressure. Methods One-hundred and fifty-five essential hypertensive patients with stroke history were randomly assigned to either perindopril group or placebo group, receiving a randomized, double-blind, placebo-controlled trial as long as 3 years. Their blood pressure, the morbidity and mortality of cardiocerebral complications were monitored. At the end of trial, three days Ambulatory Blood Pressure Monitoring were performed. Result It was shown that in perindopril group blood pressure was controlled satisfactorily, and the morbidity and mortality of cardiocerebral incidences (6.85 % and 2.74 %repectively) were lower than those of placebo group (17.10% and 9.21% respectively). Conclusions Perindopril lowers blood pressure effectively and persistently. It has important clinical effect for prevention the cardiocerebral complications in hypertensive patients with stroke history by lowering blood pressure.
Objective To evaluate the fixation strength of expansive pedicle screw (EPS) at different bone mineral density (BMD) levels, further to provide theoretical evidence for the clinical application of the EPS in patients with osteoporosis. Methods Fresh human cadaver spines (T12-L5 spines) were divided into 4 levels: normal BMD, osteopenia, osteoporosis, and severe osteoporosis according to the value of BMD, 12 vertebra in each level. Conventional pedicle screw (CPS) or EPS was implanted into the bilateral vertebra in CPS group and EPS group, respectively, 12 screws in each group per BMD level. Screw pullout tests were conducted. The maximum pullout strength, stiffness, and energy absorption were determined by an AG-IS material testing machine with constant rate of loading in a speed of 5 mm/ min. Results With the decline of BMD from normal to severe osteoporosis level, the maximum pullout strength and the stiffness correspondingly declined (P lt; 0.05). In CPS group, the energy absorption gradually decreased (P lt; 0.05); in EPS group, significant difference was found between other different BMD levels (P lt; 0.05) except between normal BMD and osteopenia and between osteoporosis and severe osteoporosis (P gt; 0.05). At the same BMD level, the maximum pullout strength of EPS group was significantly larger than that of CPS group (P lt; 0.05); the stiffness of EPS group was significantly higher than that of CPS group (P lt; 0.05) except one at normal BMD level; and no significant difference was found in the energy absorption between 2 groups (P gt; 0.05) except one at osteopenia level. No significant difference was found in maximum pullout strength, stiffness, and energy absorption between EPS group at osteoporosis level and CPS group at osteopenia level (P gt; 0.05); however, the maximum pullout strength, stiffness, and energy absorption of EPS group at severe osteoporosis level were significantly lower than those of CPS group at osteopenia level (P lt; 0.05). Conclusion Compared with CPS, the EPS can significantly improve the fixation strength, especially in patients with osteopenia or osteoporosis.
