Objective To establish the quality standard for Ziyin Mingmu tablets. Methods TLC method was used to identify Moutan Cortex, Corni Fructus, Notopterygii Rhizoma et Radix and Acori Tatarinowii Rhizoma. HPLC method was used to determine the content of Salvianolic acid B. Kromasil ODS column (250 mm×4.6 mm, 5μm) was adopted by using MeOH-acetonitrile-1.67%methanonic acid water solution (24∶10∶66) as the mobile phase. The detection wavelength was at 284 nm, column temperature was at 30℃, and the flow rate was 1.0 mL/min. Results The TLC spots were clear without interference of the negative control. The linear range of Salvianolic acid B was within 0.32-1.92 μg (r=0.999 9). The average recovery was 99.91% (RSD=0.63%). Conclusion The method is specific, reproducible and accurate, and can be used for the quality control of Ziyin Mingmu tablets.

Objective To explore the difference in pulmonary function between chronic obstructive pulmonary disease (COPD) and overlap syndrome patients.Methods 50 hospitalized COPD patients who were randomly recruited were divided into two groups, which contained 33 COPD patients and 17 overlap syndrome patients respectively. All the 50 patients’pulmonary function was evaluated and the results were analyzed statistically.Results The pulmonary function test showed that only PEF and V75 significantly decreased in overlap syndrome patients compared with COPD patients(P=0 032 and 0 048 respectively),But pulmonary volume, small airway function and pulmonary diffusion function in 5 COPD patients with severe sleep apnea syndrom (SAS) were significantly reduced compared with COPD patients.Conclusions Upper airway obstruction in SAS patients aggravates the pulmonary ventilation function in overlap syndrome. And obesity deteriorates both of the pulmonary function and hypoxemia in patients suffered from COPD.

Objective To investigate the factors related with plagiocephaly and brachycephaly. Methods 239 infants with plagiocephaly and brachycephaly were investigated, and analyzed with univariate analyses and multivariate Logistic regression analysis. Results The factors, such as gestational age birth (OR=0.636, P<0.001), birth weight (OR=0.095, P<0.001), time of hospitalization (OR=1.307, P<0.001), preterm birth (OR=2.649, P<0.001), stay in newborn intensive care unit (OR=4.456, P<0.001), change the position (OR=0.046, P<0.001), accepted early intervention guidance (OR=0.054, P<0.001), were significantly related with plagiocephaly and brachycephaly. Conclusion Preterm birth, low birth weight, and newborn complications are the risk factors for plagiocephaly and brachycephaly, while change the position and early intervention may prevent it.

Objective To investigate short?term clinical outcomes of XLIF through small incision approach combined with percutaneous pedicle screw fixation for degenerative lumbar scoliosis. Methods From December 2011 to June 2013, 15 pa?tients with degenerative lumbar scoliosis were treated by XLIF combined with percutaneous pedicle screw fixation (XLIF group). There were 6 males and 9 females, with an average age of 68.27±5.70 (ranging from 58 to 75) years old and Cobb angle of scoliosis 22.20°±6.66° (ranging from 14° to 35°). Meanwhile, 23 patients were treated with posterior lumber inter?body fusion (PLIF) com?bined with pedicle screw fixation (PLIF group). There were 9 males and 14 females, with an average age of 63.26 ± 6.03 (ranging from 49 to 73) years old and Cobb angle of scoliosis 23.17°±6.95° (ranging from 13° to 36°). The efficacy was assessed through cor?rection rate of Cobb angle, VAS and lumbar JOA score at the time of the latest follow?up. Results The operation time was 224.35 ± 51.53 min in the PLIF group and 197.47 ± 31.84 min in the XLIF group. No significant differences were found, but there was significantly difference in the intraoperative blood loss (PLIF group: 576.52 ± 227.89 ml, XLIF group: 181.33 ± 47.37 ml, t=-8.054, P<0.001). No patient accepted blood transfusion in the XLIF group, but in the PLIF group, 11 patients accepted blood transfusion. The Cobb angle, VAS and JOA score in two groups were improved compared with the preoperative. 38 patients were followed up for 12 to 32 months, with an average of 23 months. The correction rate of Cobb angle, VAS and JOA scores were 56.90%±11.51%, 87.97%±12.07%, 84.00%±5.59%in the XLIF group, and 62.88%±8.28%, 83.68%±12.33%, 84.79%±6.76%in the PLIF group. No significant differences were found between the two groups (P>0.05). Conclusion Treatment of degenerative lumbar scoliosis with XLIF through small incision approach combined with percutaneous pedicle screw fixation is a kind of safe and effective minimally invasive spine surgery with small trauma and less bleeding, and the recent surgery efficacy was close to PILF.

Objective To evaluate the effect of percutaneous transforaminal endoscopic discectomy (PTED) using tar?get puncture and 2-stage procedures in treating lumbar disc hernia. Methods Patients present in our clinic from January 2014 to June 2014 with lumbar disc hernia who were treated with PTED were collected (n=36). Lower back and leg pain were evaluated by visual analog scale (VAS) while clinic outcome were assessed by Oswestry disability index (ODI) and modified Macnab criteria. Results All surgeries were carried out successfully. On average, operation time was(125±31)min, blood loss was(8.5±2.9)mL in each operation. The average length in hospital stay was(7.6±3.5)day. Compared with the preoper?ative VAS scores,the postoperative and last follow-up scores for lower back and leg pain decreased significantly (P<0.01). The ODI of pre-operation and last follow-up were (18.90 ± 7.78)%and (73.30 ± 18.21)%respectively with statistic differ?ence. As to the modified Macnab criteria,theexcellent and goodratio was 94.4%. One case present hyperalgesia in L4 der?matome which recovered through conservative treatment. No complications such as permanent nerve root injury ,cerebrospi?nal fluid leakage,or infection were found during or after operations. All patients are in stable conditions during follow-up pe?riod without recurrence. Conclusion PTED using target puncture and 2-stage procedures is an effective method with mini?mal trauma, less bleeding, quick recovery, high security, short hospitalization time. what′s more, it can remove protruded disc and broken nucleus from the intervertebral space. It ensure efficacy and avoid recurrence.

Objective To develop and test a stressor scale for in-patients with spinal cord injury (SSIPSCI). Methods Based on in-depth interviews and the second-level International Classification of Functioning, Disability, and Health (ICF) categories, a 39-item SSIPSCI was generated and pilot tested. It was then used with 284 inpatients with spinal cord injury. Principal components factor analysis and correlation analysis were performed.Results The exploratory components factor analysis revealed 7 significant stress factors: social activity, economy security, individual activity, relationship with others, physical disorders, bowel and bladder problems and medical fees. Internal consistency was high, with a Cronbach's alpha coefficient of 0. 950 overall and 0. 741 ～ 0. 920 for the individual factors. Test-retest reliability was 0.848. The correlation between SSIPSCI scores and Beck depression inventory (BDI) scores was strong ( r = 0. 665 ). Conclusions The reliability and validity of the SSIPSCI are both satisfactory enough to meet psychometric requirements.
