OBJECTIVE:To investigate the effects of rosuvastatin combined with berberine hydrochloride on related indexes in patients with acute cerebral infarction.METHODS:Medical information of 120 patients diagnosed as acute ischemic cerebral infarction were analyzed retrospectively,and they divided into observation group (65 cases) and control group (55 cases) according to route of administration.Both groups were given routine treatment;control group was additionally given Rosuvastatin calcium tablets 10 mg orally before bedtime,once a day;observation group was additionally given Berberine hydrochloride tablets 0.3 g orally,3 times a day,on the basis of control group.Treatment courses of 2 groups lasted for 14 d.The levels of TC,TG,LDL-C,HDL-C,hs-CRP,ox-LDL,NIHSS score,ADL score,TPA,IMT,Crouse score,the number of unstable plaque and ADR were observed and compared between 2 groups before and after treatment.RESULTS:Before treatment,there was no statistical significance in above indexes between 2 groups (P＞0.05).After treatment,the serum levels ofTC,TG,LDL-C,hs-CRP and ox-LDL in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,with statistical significance (P＜0.05).After treatment,NIHSS score of 2 groups were significantly lower than before,and ADL score,HDL-C levels were significantly higher than before,with statistical significance (P＜0.05);there was no statistical significance between 2 groups (P＞0.05).After treatment,there was no statistical significance in IMT,Crouse score and the number of unstable plaque in control group compared to before treatment (P＞0.05),but in observation group were significantly lower than before treatment,and also lower than control group at corresponding period,with statistical significance (P＜0.05).There was no statistical significance in TPA between 2 groups before and after treatment(P＞0.05).There was no statistical significance in the indcidence of ADR between 2 groups during treatment(P＞0.05).CONCLUSIONS:Based on routine treatment,rosuvastatin combined with berberine hydrochloride could effectively reduce blood lipid levels in patients with acute cerebral infarction,stabilize or reverse atherosclerotic plaque,and reduce inflammation and oxidative stress with good safety.

BACKGROUND:Distal femoral fractures are mainly treated with less invasive stabilization system (LISS) plate or retrograde interlocking intramedul ary nail fixation, but choosing which method is controversial, and studies on their biomechanical properties are few. OBJECTIVE:To compare the biomechanical stability of retrograde interlocking intramedul ary nail and LISS plate fixation in the treatment of distal femoral fractures. METHODS:Twelve male cadaveric femurs were col ected, and the injured, with abnormal bone density and osteonosus specimens were excluded through X-ray examination, fol owed by randomly divided into two groups. Models of AO type A3 supracondylar fracture were prepared, and were fixed with LISS plate and retrograde interlocking intramedul ary nail, respectively. The compressive stiffness and displacement values under axial compression and loading of 100, 300 and 500 N, as wel as the bending strength of the specimens under bending load were observed. RESULTS AND CONCLUSION:(1) The resistance to axial deformation capacity (compressive stiffness) of the LISS plate was superior to the retrograde interlocking intramedul ary nail (P<0.05);while the resistance to bending deformation capacity (flexural strength) of the retrograde interlocking intramedul ary nail was not significantly greater than that of the LISS plate (P>0.05). (2) Under axial compressive loading of 100, 300 and 500 N, the displacement values of LISS plate were significantly less than those of the retrograde interlocking intramedul ary nail (P<0.05). (3) In conclusion, in the distal femoral fracture fixation, the stiffness of the retrograde interlocking intramedul ary nail is low. While the LISS plate not only has certain deformation, but also has strong rigidity with firm internal fixation, which provides excel ent biological environment for fracture healing;thus it is a reliable treatment for distal femoral fractures.

Objective To evaluate the long term curative effects of radiotherapy combined with photodynamic therapy on the advanced esophageal cancer.Methods From Oct 1991 to Dec 1992, 60 patients with advanced esophageal cancer were randomly divided into two groups, 30 patients received conventional radiotherapy alone (CRT), the other 30 cases received radiotherapy combined with photodynamic therapy (PRT). After PRT the total dose of 40Gy,for 4 weeks the hematoporphyrin derivate(HpD) was given using 5mg/kg body intravenously and after 48 and 72 hours,the location of lesion were irradiation by 630-nm red light with 400～500mW/cm 2. Laser irradiation was given for 15 minutes to each part of tumor.Results The 5,10-year survival rates were 16 7% ,10 0% respetively;for CRT group and 29 9%, 16 7% respectively; for PRT group, The difference was significant (P

0 05).The survival rate of 1,2,3-year of SG and CRG respectively were 72 58%,51 61% and 37 10%,and 58 10%,32 26% and 20 97%.There was significant difference in the survival rate of 2,3-year between two groups(P

Objective:To investigate the value of prenatal ultrasound combined with MRI in the diagnosis and differential diagnosis of fetal pulmonary sequestration.Methods: The prenatal examination data of 9 cases with pulmonary sequestration confirmed by autopsy and postnatal follow-up was analyzed retrospectively. All fetuses were examined by MR examination performed within 24 hours after ultrasound examination. The results of prenatal ultrasound and MRI were analyzed, and the results were compared with the follow up results.Results: The diagnostic accuracy of ultrasound was 77.78%(7/9), 2 cases were misdiagnosed(one case was misdiagnosed as abdominal mass and one case as pulmonary cystadenoma). The diagnostic accuracy of MRI was 100%.Conclusion: Prenatal ultrasound is the primary method for pulmonary sequestration. As the supplement, MR can display directly the location, shape, size of the lesion. There is high value in diagnosis and differential diagnosis of fetal pulmonary sequestration. The combination of ultrasound and MRI can further improve the diagnostic accuracy of the disease.

Objective To explore the levels of serum 25(OH)D in glomerular disease patients and investigate its influence on the impaired glucose metabolism after treated with glucocorticoid. Methods A total of 61 patients with glomerular disease confirmed by clinical diagnosis and renal biopsy were included in the case group before receiving steroid therapy. 16 cases were selected as control at the same period. Before and six weeks after the treatment of glucocorticoid, all subjects took oral glucose tolerance test (OGT). According to the results of OGT, patients were divided into normal glucose regulation (NGR) group, impaired glucose regulation (IGR) group and steroid diabetes mellitus (SDM) group. Serum 25(OH)D levels were detected with enzyme?linked immunosorbent assay (ELISA), and other clinical data including albumin(Alb), Scr and urine protein were collected. Results (1) Before treated with glucocorticoid, the serum 25(OH)D levels in the control group [(64.09±13.53) nmol/L]were significantly higher than that in NGR group [(50.81 ± 12.44) nmol/L], while the latter was significantly higher than that in IGR group [(42.71 ± 8.09) nmol/L, all P<0.05]. In the glomerular disease patients, 18 cases (29.51%) were 25(OH)D insufficiency and 39 cases(63.93%) were 25(OH)D deficiency. 25(OH)D levels in patients with nephritis were significantly higher than in patients with nephroitic syndrome[(56.94 ± 10.41) nmol/L vs (45.88 ± 11.55) nmol/L, P<0.05]. (2)6 weeks after the treatment, incidence of steroid diabetes in IGR group was significantly higher than that in NGR group (61.11% vs 20.93%, P<0.05). Baseline levels of 25(OH)D in NGR group and IGR group were all significantly higher than that in SDM group [(55.68 ± 13.09) nmol/L, (48.97 ± 9.91) nmol/L vs (40.91 ± 7.82) nmol/L, all P<0.05]. (3)Serum levels of 25(OH)D were positively correlated with serum albumin and serum calcium, and negatively correlated with BMI, urinary protein, cholesterol and the 2 hours postprandial blood glucose. (4)Logistic regression analysis indicated that 25(OH)D<50 nmol/L and HbA1c>5.6% increased the risk of developing steroid diabetes 5.586 and 5.197 times, respectively. Age increased 10 years or insulin resistance index increased one, the risk of occurred SDM increased 2.443 and 2.755 times, respectively. Conclusions Most glomerular disease patients are serum 25 (OH)D deficiency or insufficiency. Low level of serum 25(OH)D is one of the main risk factors of steroid diabetes in patients with glomerular disease when treated with glucocorticoid.
