To investigate the effect of atorvastatin on lipid metabolism in type 2 elder diabetes patients with hyperlipidemia, 26 patients with type 2 elder diabetes complicated with hyperlipidemia were treated with atorvastatin (10 mg/d) for 8 weeks. The serum triglyceride (TG), high density protein cholesterol (HDL-C) and low density protein cholesterol (LDL-C) were measured before and after the treatment. Meanwhile, the non-denaturing polyacrylamide gradient gel electrophoresis was used for detection of small-sized LDL(SLDL). Our results showed that TG dropped from 4.88 +/- 0.72 mmol/L to 2.65 +/- 0.32 mmol/L; HDL-C was increased from 0.85 +/- 0.31 mmol/L to 1.28 +/- 0.29 mmol/L; LDL-C was declined from 3.71 +/- 2.98 mmol/L to 2.10 +/- 1.22 mmol/L, sLDL-A was increased from (42.49 +/- 8.1)% to (53.27 +/- 7.5)%; LDL-B was decreased from (57.91 +/- 8.1)% to (46.73 +/- 7.5% ) (P<0.05). The level of blood glucose was not changed at the end of 8th week. It is concluded that atorvastatin has satisfactory lipid-regulating effects on type 2 elder diabetes patients with hyperlipidemia.

Objective To systematically evaluate the efficacy and safety of posterior short segment and long segment pedicle screw internal fixation in the treatment of thoracolumbar burst fracture. Methods By searching the database, including PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, a comprehensive study was carried out to make a comparison between the posterior short segment and the long segment pedicle screws internal fixation in treatment of thoracolumbar burst fracture, and Meta analysis was performed. Results A total of 14 related studies and 658 patients were enrolled in the study, including 320 patients in short segment group and 338 cases in long segment group, and Meta analysis was performed. The results suggested that there was no significant difference between the short segment group and the long segment group in terms of the deformity angle of the injured vertebra measured after operation and at the last follow?up, and sagittal index at the last follow?up ( MD=-0. 22,95%CI -2. 73,2. 28,P=0. 86;MD=-0. 28,95%CI -2. 23,1. 67, P=0. 78;MD=0. 47, 95%CI -3. 45, 4. 39, P=0. 81 ) . Besides, both groups had no statistical difference in post?operative COBB angle,anterior vertebral height and compression rate of injured vertebrae ( MD=0. 21,95%CI -0. 65,1. 06,P=0. 64; MD=-0. 46,95%CI -1. 40,0. 49,P=0. 34; MD=0. 47,95%CI -2. 28, 3. 21, P= 0. 74 ) , while the differences in COBB angle, anterior vertebral height, compression rate, correction loss were statistically significant at the last follow?up (MD=5. 11,95%CI 2. 81,7. 40,P<0. 0001;MD=-11. 89,95%CI-15. 28,-8. 50,P<0. 00001;MD=6. 46,95%CI 3. 85,9. 07,P<0. 00001) . There was no significant difference in VAS scores and the ODI scores between the two groups at the last follow?up ( MD =0. 01,95%CI -0. 15,0. 17,P=0. 9; MD=-0. 47,95%CI -2. 68,1. 74,P=0. 86),while the two groups showed statistically significant difference in fixation failure ( RR = 0. 08, 95%CI 0. 01, 0. 15, P = 0. 02 ) . Conclusion Posterior long segment pedicle screw internal fixation is more effective in treating thoracolumbar burst fracture than short segment surgery. It can reduce the COBB angle,restore the anterior height of the injured vertebra,and decrease the anterior vertebral pressure.

OBJECTIVE: To establish the linear regression equation between body height and combined length of manubrium and mesostenum of sternum measured by CT volume rendering technique (CT-VRT) in southwest Han population. METHODS: One hundred and sixty subjects, including 80 males and 80 females were selected from southwest Han population for routine CT-VRT (reconstruction thickness 1 mm) examination. The lengths of both manubrium and mesosternum were recorded, and the combined length of manubrium and mesosternum was equal to the algebraic sum of them. The sex-specific linear regression equations between the combined length of manubrium and mesosternum and the real body height of each subject were deduced. RESULTS: The sex-specific simple linear regression equations between the combined length of manubrium and mesostenum (x3) and body height (y) were established (male: y = 135.000+2.118 x3 and female: y = 120.790+2.808 x3). Both equations showed statistical significance (P < 0.05) with a 100% predictive accuracy. CONCLUSION CT-VRT is an effective method for measurement of the index of sternum. The combined length of manubrium and mesosternum from CT-VRT can be used for body height estimation in southwest Han population.

The dosage-efficacy/toxicity relationship of the 50% alcohol extracts of Polygonum multiflorum was comparatively investigated on either normal or CCl4-induced chronic liver injury rats, by determining the general condition, serum biochemical indices and liver histopathology, coupled with the factor analysis. The dosages were 10 and 20 g raw materials per kg body weight. Compared with the normal control group, the normal high dose group showed significant increases of the serum alanine transaminase (ALT), total bilirubin (TBIL), high mobility group box 1 (HMGB-1) and interleukin-1β (IL-1β) (P < 0.05 or P < 0.01), as well the frequent incidences of inflammatory cell infiltration, hepatic sinus enlargement and fiber stripes formation in histopathological sections. Compared with the model control group, the model low dose group showed significant declines of serum ALT, aspartate transaminase (AST) and total bile acid (TBA) (P < 0.05), as well the alleviation of vacuoles of hepatocytes, but no amelioration of the inflammatory cell infiltration and fibrous tissue hyperplasia; moreover, the model high dose group showed significant degeneration declines of serum HMGB-1, tumor necrosis factor-α (TNF-α) and IL-1β (P < 0.05, P < 0.01), as well the evident alleviation of vacuoles degeneration of hepatocytes, inflammatory cells infiltration and fibrosis degree. The factor analysis showed that the low dosage treatment had almost neither injuring effect on the normal rats nor protective effect on the model rats; while the high dosage treatment showed observable injuring effect on the normal rats, expressed by the significant increases of the factor-1 (HMGB-1, TNF-α and IL-1β as the main contributors) and factor-2 (TBIL, ALT and TBA as the main contributors) relative to the normal control group. The liver protective effect of the high dosage treatment could be observed with the significant reduction of the factor-1, indicating the effective alleviation of the expression of inflammatory cytokines. In conclusion, it could illustrated the phenomenon of symptom-based prescription theory of Polygonum multiflorum on rat livers: the high dosage of the herb had either an injuring effect on normal rats, or a therapeutic effect on the rats with chronic liver injury.

OBJECTIVETo analyze the correlations between increased spinal cord signal intensity on magnetic resonance images (MRI) and the clinical prognosis of compressive cervical myelopathy.

METHODSSixty-six patients with cervical spondylotic myelopathy underwent surgeries through the anterior approach. In all the patients, the diagnoses were established on the basis of both neurological examination and MRI findings that showed spinal cord compression. The patients were divided into two groups according to preoperative MRI, namely isointense MRI T1/T2 signal group and iso/hyperintense MRI T1/T2 group. The JOA scores of the patients were evaluated before and at 6 and 12 months after the operation.

RESULTSThe patients were followed up for 12 to 38 months after the operation (mean 21 months), and no statistically significant difference were found in the pre- and postoperative JOA scores between the two groups (P>0.05).

CONCLUSIONThe peoperative hyperintense signals on T2 weighted MRI does not correlate to the prognosis of patients with compressive cervical myelopathy, who may also have favorable clinical outcomes after the operation.

Autophagy plays important roles in modulating viral replication and antiviral immune response. Coronavirus infection is associated with the autophagic process, however, little is known about the mechanisms of autophagy induction and its contribution to coronavirus regulation of host innate responses. Here, we show that the membrane-associated papain-like protease PLP2 (PLP2-TM) of coronaviruses acts as a novel autophagy-inducing protein. Intriguingly, PLP2-TM induces incomplete autophagy process by increasing the accumulation of autophagosomes but blocking the fusion of autophagosomes with lysosomes. Furthermore, PLP2-TM interacts with the key autophagy regulators, LC3 and Beclin1, and promotes Beclin1 interaction with STING, the key regulator for antiviral IFN signaling. Finally, knockdown of Beclin1 partially reverses PLP2-TM's inhibitory effect on innate immunity which resulting in decreased coronavirus replication. These results suggested that coronavirus papain-like protease induces incomplete autophagy by interacting with Beclin1, which in turn modulates coronavirus replication and antiviral innate immunity.

Objective:To evaluate the effect of supervised high-intensity interval training(HIIT)on physical fitness of elderly patients with type 2 diabetes mellitus.Methods:In a prospective randomized controlled study, 47 elderly type 2 diabetes mellitus patients were randomized into either the HIIT group(n=24)or the control group(n=23). All HIIT sessions were conducted under supervision once every other day for 10 weeks.Each session included 40 cycles that consisted of high-intensity training(resting oxygen consumption + 80% oxygen consumption reserve)for 30 seconds and low-intensity training(resting oxygen consumption + 50% oxygen consumption reserve)for 30 seconds.Cardiopulmonary exercise testing, bioelectric impedance analysis and homeostasis model assessment-2(HOMA-2)were used for the measurement of physical fitness, body composition and insulin sensitivity(HOMA-2 IS)before and after intervention. Results:After 10 weeks, peak oxygen uptake(23.6±4.1 ml·kg -1·min -1vs.21.0±4.6 ml·kg -1·min -1, P<0.05), oxygen uptake at the anaerobic threshold(14.1±1.6 ml·kg -1·min -1vs.12.1±2.3 ml·kg -1·min -1, P<0.01), oxygen pulse at the anaerobic threshold(10.7±2.6 ml/min vs.(9.3±1.9)ml/min, P<0.05)and Ln(100·HOMA-2 IS)(4.6±0.4 vs.4.2±0.5, P<0.01)improved in the HIIT group more than in the control group.There were no significant differences in body composition between the two groups( P>0.05). After adjusting for age and body mass index, there was a linear correlation between peak oxygen uptake and Ln(100·HOMA-2 IS)at baseline( r=0.376, P<0.05), but not between changes in peak oxygen uptake and changes in Ln(100·HOMA-2 IS)( r= 0.05, P>0.05). Conclusions:Ten-week HIIT can improve physical fitness of elderly type 2 diabetes mellitus patients.The benefit comes not only from improvement of insulin sensitivity but also from enhancement of heart function.
