Objective To observe the effects of electro-acupuncture on the expression and inhibition of DNA binding protein 2 (Id2) and myelin basic protein (MBP),and to explore the mechanism of remyelinization after compressive spinal cord injury (CSCI) in rats.Methods Fifty-four SD rats were randomly divided into a control group and a treatment group,and each was further subdivided into 3 time point subgroups:3,7 and 14 days.There were 9 rats in each subgroup.The CSCI models were made with a self-designed method.The acupuncture points Jiaji (EX-B2),bilateral Zusanli (ST36) and Taixi (KI3) were selected for treatment.Electro-acupuncture (continuous wave,2 Hz,1.5 V)was applied to the bilateral Zusanli (ST36) and Taixi (KI3) points.The control group received the injury but no treatment.The changes in the ultrastucture of the nerve fibers＇ white matter were de-termined by transmission electron microscopy (TEM).The alterations in the expression of MBP and Id2 were observed by double labeled immunofluorescence and Western blotting on the 3rd,7th and 14th day after the injury.Results TEM showed that the myelin sheaths in the control group had degenerated,swollen,and even broken down after CSCI.Changes to the myelin sheaths in the treatment group were milder than those in the control group.The immunofluorescence results showed the amount of Id2-immunoreactive oligodendrocytes in the control group to be (20 ±2) on the 3rd day after CSCI,becoming (16 ± 1) on the 14th day.The differences among the 3 control subgroups were not statistically significant.The amount of Id2-immunoreactive oligodendrocytes in the treatment group was (13 ± 1) on the 3rd day,reaching a minimum the 14th day.The differences among the 3 treatment groups were statistically significant.The differences compared with the control group at the same time points were also statistically significant.Western blotting showed that the expression of Id2 in the contrast and treatment groups was (1.12 ±0.12) and (0.67 ±0.01) respectively on the 3rd day after CSCI,and both decreased with time.The expression of Id2 in both groups reached their minima ((0.86 ±0.02) and (0.25 ±0.01) respectively) on the 14th day.The difference between the treatment groups and the contrast group was statistically significant at each time point.The expression of MBP in the contrast and treatment groups at day 3 was (0.44 ± 0.02) and (0.67 ± 0.04) respectively,and these increased with time.The expression of MBP in both groups peaked at the 14th day (at (0.95 ± 0.04) and (1.74 ± 0.09) respectively).These differences were again statistically significant.Conclusion Electro-acupuncture can regulate the expression of Id2 and MBP after CSCI.The down-regulation of Id2 which controls MBP negatively and the up-regulation of MBP may contribute to remyelination in the injured spinal cord.

Objectives To explore the clinical manifestations, treatment and prognosis of a case of blindness caused by nephrotic syndrome with cerebral venous sinus thrombosis (CVST). Methods The clinical manifestations, diagnosis and treatment of a case of NS with CVST were analyzed. The latest domestic and foreign reseach progresses in treatment for CVST in children were reviewed. Results Epilepsy suddenly appeared with diplopia, binocular vision loss and blindness in anticoagulant therapy for the child with NS. Brain magnetic resonance venography (MRV) suggested CVST. MRV reexam-ined showed that the intracranial thrombosis was completely dissolved after urokinase thrombolysis for one month followed by ineffective heparin anticoagulation. At present, international standards of anticoagulant therapy have been adopted in the treatment for CVST patients. Coagulation function (e.g.APTT) and international standardization ratio were monitored in order to prevent bleeding. Conclusions It is better to perform neural imaging examination early in suspected CVST patients. Anti-coagulation and thrombolytic therapy should be given immediately once the risk of bleeding was excluded and used for 3-6 months.

Hela is the cell line of adenocarcinoma of the uterine cervix, and human papillomavirus (HPV) 18 shows positive. We delivered siRNA with target specifically to HPV18 E7 mRNA into nude mice Hela tumor xenografts by nanopatch to inhibit the HPV gene expression, and further to study the superiority, the best action time and concentration of siRNA of using nanopatch to transfer siRNA in vivo. We designed siRNA that target specifically to HPV18 E7 mRNA (siE7) and checked the effect of siE7 in vitro. Tumor xenografts were transfected with siE7 and GenEscort III by nanopatch. Expression of HPV18 E7 mRNA and protein were detected 0 hours, 24 hours, 48 hours, 72 hours after transfection with PT-PCR and Western blot, and the best action time was analyzed using nanopatch to thansfect siRNA in vivo. We transfected GenEscort III and siE7 of Different concentration into tumor xenografts respectively by nanopatch and intraperitoneal injection. Expression of HPV18 E7 mRNA and protein was detected 72 hours after transfection by PT-PCR and Western blot, to analyze the best action concentration of siRNA and the superiority of using nanopatch to thansfect siRNA in vivo. The results proved that SiE7was efficient to inhibit expression of HPV18 E7 mRNA and to advance Hela apoptosis in vitro. SiE7 transfected by nanopatch into xenografts could inhibit effectively expression of HPV18 E7 mRNA and protein. The best action time and concentration of siRNA of using nanopatch to thansfect siRNA in vivo are 72 hour post-transfection and 2 micromol/L siE7. To compare intraperitoneal injection in delivering siRNA in vivo, the effect of nanopatch is very predominant. It can be well concluded that Nanopatch can effectively transfer siRNA in vivo, which can effectively inhibit the HPV gene expression.

Objective To observe the clinical efficacy of Tanreqing Injection combined with levofloxacin injection in treatment of acute episode of chronic bronchitis and its effect on bacterial clearance rate. Methods Totally 66 patients were randomly divided into treatment group and control group (33 cases for each). Both groups were given expectorant and antispasmodic treatment. The treatment group was given Tanreqing Injection combined with levofloxacin injection, while the control group was given levofloxacin injection only. The treatment course was 12 days. The clinical symptoms, signs, and sputum culture before and after treatment were observed. The clinical efficacy and the bacterial clearance rate of the two groups were compared. Results The markedly effective cases and the effective cases in the treatment group were 15 and 29 respectively, and those in the control group were 7 and 21 respectively, with statistical significance (P<0.05). The bacterial clearance rate was 89.5% (17/19) in the treatment group, while 55.6%(10/18) in the control group, with significant difference (P<0.05). Conclusion Acute episode of chronic bronchitis treated by Tanreqing Injection combined with levofloxacin injectcion is more effective than levofloxacin injection only.

Objective To analyze the risk factors for perioperative acute cerebral vascular accident (PACVA) and put forward the corresponding preventive measures.Methods The clinical data of elderly patients in our hospital who suffered from PACVA in recent 5 years were retrospectively studied.The correlation between risk factors and the occurrence of PACVA was analyzed.Results One hundred and fifty cases were enrolled in the study.Seventy eight cases of them suffered from PACVA with the average age of 70 years ranging from 60 to 98 years.Fifty six cases(71.8%)were found PACVA in one week after operation.Multiple regression analysis showed that hypertension, history of cerebrovascular disease, unstable blood pressure and obesity were independent risk factors for PACVA.The newly diagnosed perioperative atrial fibrillation and carotid atheroselerosis were the high risk factors for PACVA.Conclusions PACVA is one of the common perioperative complications.Necessary check, monitor and treat measures should be taken in the perioperative period, especially for patients with risk factors.
