Ohjective To observe the inhibition effect of total glucosides of Picrorhiza on hepatitis B virus covalently closed circular DNA (HBV cccDNA) in HepG 2.2.15 cell line. Methods HepG 2.2.15 cells were incubated with culture medium containing 50 mg/L of picrosides or 5 mg/L of adefovir dipivoxil for 2 or 5 days. HBV DNA in the supernatant, intracellular cccDNA, relaxed circular DNA (rcDNA) and pregenomic RNA (pgRNA) were quantified by specific real-time polymerase chain reaction (RT-PCR) and inhibition rates were calculated. The means were compared by t test. Results After treated with picrosides for 2 and 5 days, the inhibition rates of HBV DNA in thesupernatant were 49. 74% (t=4.723, P<0.05) and 79.48% (t = 7.512, P<0.05), respectively. The inhibition rates of intracellular cccDNA were 43.55% (t = 5.216, P<0.05) and 56.43% (t=7.262, P<0.05), respectively, while those of intracellular rcDNA were 43.39% (t=4.137, P<0.05) and 63.86% (t=7.861, P<0.05), respectively, and those of intracellular pgRNA were 54.72% (t=4.532, P<0.05) and 56.08% (t=4.833, P<0.05), respectively. Comparatively, after treatment with adefovir dipivoxil for 2 and 5 days, the inhibition rates of HBV DNA in the supernatant were 25.56% (t=2.874, P<0.05) and 92.44% (t =10.276, P<0.05), respectively. Those of cccDNA were 18.54% (t=2.736, P<0.05) and 47.19% (t=6.852, P<0.05), respectively. Those of rcDNA were 21. 20% (t=3.206, P<0.05) and 71.47% (t=8.332, P<0.05), respectively, pgRNA were 11.14% (t=1.761, P>0.05) and 37.61%(t=3.632, P<0.05) respectively in HepG2.2.15 cells. Conclusions Pierosides may inhibit the replication cycle of HBV, including the formation of cccDNA in HepG 2.2.15 cells. The mechanism of pierosides on cccDNA may differ from adefovir dipivoxil's due to its earlier inhibition time phase.

Objective To investigate the effect of endovascular treatment of intracranial ruptured vertebral artery dissecting aneurysms via bilateral vertebral artery approach. Methods The symptoms and imaging results of 5 patients with ruptured vertebral artery dissecting aneurysms were analyzed retrospectively. They were all treated with coil embolization via bilateral vertebral artery approach. The two ends of dissection aneurysms were packed densely,the middle segments were packed loosely,and the arteries were isolated from the blood circulation. Results Of the 5 patients after treated,the clinical symptoms were improved rapidly in 4 patients no abnormal limbs activity and mental disorders. After treatment,the modified Rankin scale (mRS)was 0 in four cases after six-month follow-up. One patient turned clear consciousness after 4 weeks, and their mRS was 3 at 6-month follow-up. Before treatment,DSA showed vertebral artery dilation and stenosis. The mean length of involvement in vertebral arteries was 9. 3 ± 1. 5 mm;after treatment,the dissecting aneurysms of 5 patients did not develop completely,no further bleeding occurred,and no new infarcts were observed. No recurrence of the aneurysms and parent artery recanalization were found at the follow-up after 6 months. Conclusion The occlusion of ruptured vertebral artery dissecting aneurysms via bilateral vertebral artery approach is technically feasible. It may be an effective treatment to prevent rebleeding.

Objective To assess the functional restoration in patients with developmental dysplasia of the hip (DDH) who underwent hip resurfacing arthroplasty and to determine whether greater abduction angle of the acetabular component is relat?ed to larger diameter of femoral head component. Methods We reviewed 34 DDH cases (9 hips of 8 males and 25 hips of 24 fe?males, mean age 44.6±11.85 years at the time of surgery) on whom we performed hip resurfacing arthroplasty (HRA) from October 2006 to September 2009. The total hip Arthroplasty (THA) group was consisted of 35 DDH cases (8 hips of 8 males and 27 hips of 25 females, mean age 43.7±10.4 years at the time of surgery). All operations were performed by the same doctor over the same peri?od. Assessment of the functional hip scores was conducted by Harris Hip Scores. A radiographic study was also performed to evalu?ate the implants stability and abduction angle of the acetabular components. All the data was analyzed with Kolmogorov?Smirnov method. Results The mean follow?up was 6.2 years in the HRA group. The Harris Hip Score improved from 54.9±13.2 to 97.3± 6.2 after the surgery. The mean abduction angle of the acetabular component was 51.6° ± 5.33°, hip flexion was 127° ± 6.9° and mean diameter of femoral head was 46.5±1.5 mm. The mean follow?up was 5.9 years in the THA group. The Harris Hip Score im?proved from 51.6±19.7 to 95.6±7.9 after the surgery. The mean abduction angle of the acetabular component was 43.9°±4.90°, hip flexion was 117°±4.2°. There was no failure of the prosthesis, peri?prosthetic fracture and infection in either group. There was sig?nificant difference in the abduction angle of the acetabular component (P<0.05) and flexion of the hip between the two groups (P<0.05). Conclusion Patients in the HRA group had a better functional restoration and larger range of motion. Furthermore, a larger diameter of femoral head component could be achieved by placing the acetabular component in a greater abduction angle, which may contribute to a better long?term stability.

Objective To evaluate the quality of life for tuberculosis patients after anterior debridement, autograft bone fusion and anterolateral fixation operation. Methods 17 cases of thoracolumbar spinal tuberculosis were treated surgically from January 2008 to March 2011. All the cases underwent anterior debridement, autograft bone fusion and anterolateral fixation operation. MOS health survey 36-item Short Form (SF-36), Japanese Orthopaedic Association Scores (JOA) and Visual Analogue Scale (VAS) were used to evaluate the quality of life, spine function and pain symptom before and 1 and 6 months after surgery. Results Compared to the results 1 month after surgery, the scores of physical function (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social function (SF), role emotional (RE), and mental health (MH), and JOA subjective symptoms, JOA clinical signs, and JOA daily activity limitation, and VAS improved (P<0.05) 6 months after surgery; compared to pretreatment, the scores of PF, BP, GH, VT, SF, and MH, and JOA subjective symptoms, JOA clinical signs, and JOA daily activity limitation, and VAS improved (P<0.05). Conclusion The anterior debridement, autograft bone fusion and anterior fixation operation is effective to improve the quality of life, spine function and pain symptom for tuberculosis patients.

Objective To investigate the feasibility and effectiveness of endovascular treatment of posterior communicating artery aneurysm (PcoAA)in keeping the fetal posterior cerebral artery (FPCA) patency. Methods Form January 2014 to December 2015,14 patients with ruptured PcoAA enrolled retrospectively were treated with endovascular embolization. Six of them were treated with simple coil embolization,3 with stent-assisted coil embolization,3 with double catheter-assisted coil embolization,1 with stent-assisted coil embolization + double catheter technique,and 1 with Y-stent in Yijishan Hospital, Wannan Medical College. The immediate embolization rate of PcoAA (using Raymond grade),prognosis of the patients (the modified Rankin scale score at 6 months after procedure),complications,and imaging follow-up results were analyzed. Results The success rate of coil and stenting was 100% . All the stents were accurately released in place without displacement. The immediate Raymond grading of the aneurysms displayed that Raymond grade Ⅰ was in 8 cases,Raymond grade Ⅱ was in 4 cases,and Raymond grade Ⅲ was in 2 cases. All FPCA were kept patent. A coil protruded into internal carotid artery in one case during the procedure. Others did not have any complications,such as intraoperative cerebral vasospasm,in-stent thrombosis,and rupture. All 14 patients were followed up for 3 -24 months after procedure. Two had recurrence. Both were aneurysms embolized with coils only. No rebleeding and ischemic
complications were observed. The modified Rankin scale scores in 13 cases were 0 -2 at 6 months after procedure,1 was 4. Conclusions Endovascular embolization for the treatment of PcoAA and keeping FPCA patency are safe and feasible. A variety of endovascular treatment modalities are necessary in order to keep FPCA patency.

Objective To investigate the risk factors for influencing recrudescence after endovascular embolization of posterior communicating artery aneurysms.Methods From January 2014 to December 2014,71 consecutive patients (a total of 74 aneurysms) with posterior communicating artery aneurysm treated with endovascular treatment at the Department of Neurosurgery,Yijishan Hosptial of Wannan Medical College were enrolled retrospectively.The aneurysms were calculated as the number of cases (n=74).The aneurysms were divided into two groups according to whether they had recrudescence or not,including recurrent group (n=18) and non-recurrent group (n=56).The differences of the clinical data and aneurysm characteristics between the two groups were compared.Multivariate logistic regression was used to analyze the risk factors for recrudescence after endovascular embolization of posterior communicating artery aneurysms.Results Of the 74 patients with aneurysm,51 were treated with simple coil embolization and 23 were treated with stent-assisted coil embolization.All the coils were released satisfactorily.There were significant difference in the size of aneurysms and Raymond grade between the two groups (all P<0.01).The incidence of aneurysms with daughter cysts (55.6% [10/18] and the rate of non-stent-assisted coil embolization (88.9% [16/18]) in the recurrent group were significantly higher than those in the non-recurrent group (23.2% [13/56],62.5% [35/56]).The difference between the two groups was statistically significant (all P<0.05).There was no significant difference in other aneurysm features between the two groups (all P>0.05).After variable selection,the Raymond grade was referred to Raymond gradeⅠ.Multivariate logistic regression analysis showed that the non-stent-assisted coil embolization (OR,4.789,95%CI 1.207-19.009,P=0.026),Raymond grade Ⅱ (OR,12.326,95%CI 3.838-39.592,P<0.01),Raymond grade Ⅲ (OR,36.884,95%CI 2.892-470.454,P=0.005) were the independent risk factors for recrudescence after embolization of posterior communicating artery aneurysms.Conclusion Non-stent-assisted coil embolization,Raymond Ⅱ and Ⅲ may cause recrudescence of posterior communicating artery aneurysms.

Objective:To analyze the factors influencing dysphagia after an injury to the cervical spinal cord (CPCI) to provide a basis for clinical screening and intervention.Methods:A total of 110 CPCI patients with dysphagia were divided into a severe dysphagia group ( n=19), a mild dysphagia group ( n=35), and a control group ( n=56) according to their functional oral intake scale scores. Data on gender, age, level of injury, degree of damage, duration of injury, causes of injury, surgical mode, tracheotomy status, occurrence of pneumonia and pharynx swelling were collected. Univariate and multivariate logistic regressions were evaluated to identify factors affecting swallowing. Results:The regressions highlighted age, the severity of the spinal cord injury, tracheotomy status, and the occurrence of pneumonia and pharyngeal swelling during hospitalization as the best predictors of swallowing difficulties. Multifactoral logistic regression analysis revealed that undergoing tracheotomy and catching pneumonia during hospitalization were major risk factors for severe dysphagia.Conclusions:Tracheotomy and pneumonia during hospitalization are useful predictors of severe dysphagia after a cervical spinal cord injury.
