BACKGROUND:Adolescent idiopathic scoliosis is a common disease that can affect physical appearance of adolescents in the clinic at present. However, there are lacks of studies on coronal plane imbalance after fixation using Logistic regression equation at present.
OBJECTIVE:To investigate the reasons for coronal plane imbalance after fixation in patients with Lenke type II adolescent idiopathic scoliosis.
METHODS:141 cases of Lenke type II adolescent idiopathic scoliosis admitted by Department of Spinal Surgery of the First Affiliated Hospital of Xinjiang Medical University in China from January 2001 to November 2012 were chosen as subjects. Multivariate single factor and multiple-factor Logistic regression were performed. Risk factors for the coronal plane imbalance after fixation in adolescent idiopathic scoliosis patients were screened, and predictive models were established.
RESULTS AND CONCLUSION:Coronal plane imbalance occurred in 30 of the 141 patients, accounting for 21.28%. For Lenke type II adolescent idiopathic scoliosis patients, preoperative apical vertebral Nash-More rotation level 3-4, Risser grade 4-5, major curve correction rate/flexibility>1, lower thoracic Cobb angle>70° were vulnerable to postoperative coronal plane imbalance. Multivariate logistic regression showed that vertebral rotation, Risser grade, major curve correction rate/flexibility, lower thoracic Cobb angle were independent risk factors for postoperative coronal plane imbalance in Lenke type II adolescent idiopathic scoliosis patients. The predictive model was Y=1/[1+exp(-1.182X 1+1.228X 2+1.671X 3-0.71X 4+0.407)].

Objective To study the inter-rater reliability of Wisconsin Gait Scale (WGS) and Gait Abnormality Rating Scale (GARS) in patients with stroke. Methods 20 hemiplegic patients were required to walk on their comfortable speed and videotaped from frontal, backward and lateral. The video recordings were scored with WGS and GARS by 2 experienced physical therapists. Intraclass correlation coefficient (ICC) was calculated for the scores in each category and the total score. Results ICC for the WGS were 0.372~1, and were 0~0.875 for the GARS. Conclusion WGS is more appropriater to assess the gait of hemiplegic stroke patients than GARS.

Objective To evaluate the efficacy and safety of diacerhein in the treatment of patients with knee osteoarthritis.Methods The efficacy and safety of diacerhein was randomly investigated in 42 pa- tients with knee osteoarthritis using parallel group methodology and a double-dummy technique to ensure dou- ble blind status with respect to diacerhein and control drugs diclofenac.Results Significant changes were ob- served in 20 meters walk pain,knee joint tenderness scale,WOMAC index scale,5F-36 health survey,knee joint swelling scale,compared with baseline(P＞0.05)in both diacerhein and diclofenac group respectively.No difference was found between diacerhein group and diclofenae group.The patient global assessment and physi- cian's global assessment were similar in diacerhein group and diclofenac group(P＞0.05).The side effect was similar in two groups.All of these side effects in gastrointestinal tract appeared to be transient.Conclusion Diacerhein can effectively relieve pain and swelling of knee osteoarthritis,and provides us a new effective and safe approach for treating knee osteoarthritis.

OBJECTIVETo study modified ilioinguinal approach through the retrospective analysis on the surgical treatment of 63 patients with pelvic and acetabular fractures through anterior approach.

METHODSFrom January 2006 to January 2013, 63 patients with pelvic and acetabular fractures were treated with the ilioinguinal anterior approach, including 45 males and 18 females, ranging in age from 12 to 68 years old, with an average of (37.71 +/- 13.41) years old. All the patients were divided into two groups: standard ilioinguinal anterior approach group (group A) and modified ilioinguinal anterior approach group(group B). In group A, there were 26 males and 11 females, with an average age of (38.49 +/- 13.64) years old. In group B, there were 19 males and 7 females, with an average age of (36.62 +/- 13.29) years old. Intraoperative and postoperative indicators in group A and B were observed and compared, including operation incision exposure time (from skin incision to complete the ilioinguinal in front of three "windows"), the blood loss, incision close time and treatment effect of Majeed function score.

RESULTSCompared to group A, the incision exposure time of patients in group B was shorter, the blood loss (bleeding during exposure process) was less, and the close incision time was shorter, but the treatment effect of Majeed function score had no significant differences between two groups. All the patients were followed up, and the during ranged from 3 to 36 months, with an average of (18.6 +/- 9.2) months. According to Matta standard assessment reduction of pelvic and acetabular fracture, there were 28 patients got an excellent result, 8 good, and 1 fair in the group A; and 20 patients got an excellent result, 5 good, and 1 fair in the group B. According to Majeed function score for hip function, 20 patients got a satisfactory result, 12 good,4 fair and 1 poor in group A, and the mean score was 82.51 +/- 9.72; and 13 patients got an satisfactory result, 10 good, 3 fair and 0 poor in group B, and the mean score was 80.54 +/- 10.79.

CONCLUSIONThe modified approach has several advantages as follows: providing a good surgical exposure; preventing from the injury of femoral nerve, femoral artery and vein under the inguinal ligament; not needing to open the inguinal canal, which can avoid the occurrence of inguinal hernia, reduce operation prodedures and shorten operation time.

Objective To investigate the clinical characteristics of tuberculosis (TB) first presenting as fever of unknown origin (FUO). Methods The clinical data of 100 cases of FUO, diagnosed as TB finally, among in-patients in Peking Union Medical College Hospital were analyzed retrospectively.Results ( 1 ) Sites of TB: there were 39 patients with merely pulmonary TB, 28 patients with merely extrapulmonary TB, and 33 patients with both pulmonary and extrapulmonary TB. (2) Clinical manifestations: depending on the different sites of tuberculous lesion, the clinical symptoms varied accordingly. The common laboratory findings included anemia, hypoalbuminemia, elevation of the level of ESR and C-reactive protein (CRP). (3) Methods for diagnosis: 34 cases were diagnosed by sputum smearor cultivation-positive for acid-fast bacilli; 8 cases by histopathology; 49 cases by clinical diagnosis of TB with an effective anti-TB therapy; and 9 cases by effective diagnostic anti-TB therapy. (4) Responses to treatment: among 73 cases with complete follow-up data, only 2 cases (2. 7% ) died and the other cases were cured or alleviated. Fifty-five cases (77.5%) showed marked efficacy after less than 4 weeks of regular anti-TB therapy, 37 cases ( 52. 1% ) suffered adverse effects of anti-TB agents, and all of them had improved after modifying anti-TB therapy and supporting treatment. Conclusions The diagnosis of TB that presents as FUO is quite difficult, and the median interval time for making diagnosis is 14 weeks (3-77weeks). Investigating clinical manifestations comprehensively, reviewing radiology data carefully, and eliciting microbiological and pathologic evidence of TB, are extremely important for making the correct diagnosis. In some cases, a therapeatic trial of anti-TB therapy is necessary.

Objective To study the value of magnetic resonance vessel wall imaging in assessing the atherosclerotic plaque burden of rabbit model.Methods We built up abdominal atherosclerotic animal model in 30 New Zealand rabbits by high lipid diet combined with abdominal artery denudation.The animals were divided into 3 groups randomly,which were the 1-week group,1-month group and 2-months group.The MRI and histology examination were carried out at relative time points.The correlations of area or thickness of vessel wall by MRI with histology examination were analyzed.Results Among the 30 rabbits,3 died due to anesthesia or surgery,one rabbit model failed because of the thin vessel,and another 3 died of diarrhea or inflammation during the high lipid diet feeding.Eventually,totally 23 rabbits fulfilled the examinations (7 in 1-week group,7 in 1-month group and 9 in 2-months group).The vessel wall area of histology examination grew larger along with the post-surgery duration,from 1.7663 mm2of 1-week group to 2.4371 mm2 of the 1-month group till 3.5978 mm2 of 2-months group,with statistic significant difference among 3 groups (F=5.052,P=0.017).There were strong correlations of area or thickness vessel wall resulted from MRI with histology examination(r=0.688,0.642;P=0.001,0.002).Conclusions High resolution MR vessel wall imaging technique may evaluate and follow up the plaque burden in the early stage of atherosclerosis.

OBJECTIVETo explore the theory of "Fei and Dachang being interior-exteriorly related" and the pathogenesis of lung injury by observing changes of inflammatory cytokines and oxygen free radicals in ulcerative colitis (UC) rats.

METHODSTotally 50 healthy male Wistar rats were randomly divided into two groups, the normal control group and the model group, 25 rats in each group. The UC model was established by allergizing colon mucosa combined with TNBS-alcohol (50%) enema. Another 25 rats were recruited as the normal control group. At week 2 and 4 after modeling, the pathomorphological changes of the lung were observed. Furthermore, the contents of tumor necrosis factor alpha (TNF-alpha) and IL-1beta were determined by ELISA. The activities of superoxide dismutase (SOD) and malondialdehyde (MDA) were evaluated with colorimetry.

RESULTSCompared with the normal control group, the pathomorphology of the lung tissue in the model group appeared abnormal at week 2 and 4. Compared with the normal control group, levels of TNF-alpha, IL-1beta, and MDA in the lung tissue significantly increased in the model group (P < 0. 01) and the activities of SOD significantly decreased (P < 0.05, P < 0.01).

CONCLUSIONTNF-alpha, IL-1beta, SOD, and MDA might be common material bases for the large intestine involved in lung disease of UC patients, thus providing a modern scientific basis for the theory of Fei and Dachang being interior-exteriorly related.

Objective To observe the effect of Yiqixue Buganshen Recipes(YBR), the compound recipes of Chinese herbal medicine with the actions of replenishing Qi and blood and tonifying liver and kidney, on the endometrial integrin β3 of the mice with embryo implantation dysfunction, and to explore the molecular mechanism of YBR in improving embryo implantation. Methods Ninety mice were divided normal group, model group, and YBR group, 30 mice in each group. YBR group was given Jinghou Zengzhi granules 8mg/kg for promoting post-menstruation proliferation and Cuhuangti granules 8mg/kg for promoting the formation of corpora luteum. At 8∶00 am of pregnant day 4 (Pd4), subcutaneous injection of mifepristone was used for inducing embryo implantation dysfunction in the model group and YBR group. Twenty mice from each group were executed 12 hours after subcutaneous injection of mifepristone, and the uterus was isolated for the detection of mice endometrial integrin β3 mRNA and protein expression with real-time RT-PCR and Western blotting method respectively. Ten mice from each group at Pd4 were executed, and the uterus was isolated and then fixed in 2.5% glutaraldehyde solution for the detection of the formation of pinopode in mice endometrium under scanning electron microscope. Results The detection by real-time PCR and Western blotting method revealed that integrinβ3 mRNA and protein expression levels of the model group were significantly lower than those of the normal group (P<0.05), and YBR group had higher integrin β3 mRNA and protein expression levels than the model group(P<0.05). The formation of pinopodes in the model group was less than the normal group and YBR group, but the number of formed pinopodes in YBR group was similar to that in the normal group. Conclusion YBR can up-regulate the expression of integrin β3 in the endometrium of mice with embryo implantation dysfunction, and have positive regulatory effect on the formation of pinopodes on Pd4.
