Objective To explore neural plasticity around an injured region of the spinal cord and the effects of step training on functional recovery after incomplete spinal cord injury (SCI). Methods Adult female Sprague-Dawley rats ( n = 24) were induced with spinal cord contusion at T10 and divided into a step training group and a control group ( 12 rats in each). Training started from the 7th day post-injury and lasted for (20 ± 10)min per day, 5 days per week, for 9 weeks. Treadmill speeds were 3 m/min at the beginning, and adjusted daily according to each rat's tolerance up to 11 m/min or more. The functional recovery was measured weekly with the open-field locomotor rating scale of Basso, Beattie and Bresnahan (BBB score). The expression of glial fibrillary acidic protein (GFAP), neurofilament protein (NF) and growth-associated protein-43 (GAP-43) in the spinal cord around the injured region were detected. Results After 70 days of step training, the average BBB score of the step training group reached ( 12.86 ± 0.94 ), significantly higher than that of the control group ( 10.71 ± 0.95 ). The expression of NF and GAP-43 around the injured region increased significantly more in the step training group than among the controls. Conclusions Step training can promote functional recovery and neural plasticity in rats after incomplete SCI.

Objective To analyze the relationship between the morphological characteristics and rotator cuff tear (RCT) by MR.Methods The data of clinic and shoulder MRI of 37 patients with RCT (patients group) were analyzed retrospectively,and 19 healthy volunteers were collected in control group.The acromial shapes were classified into type Ⅰ (flat),type Ⅱ (curved),type Ⅲ (hooked) and type Ⅳ (convex).Additional measurements about pathogenesis of RCT including acromio-humeral distance (AHD),acromial index (AI),lateral acromial angle (LAA) and acromial thickness were performed for further assessment.Results Type Ⅱ was the most commonly encountered acromial shape in patients group (16/37,43.24 ％) and control group (11/19,57.89 ％).There was no statistically significant difference in the incidence of each acromial shape between two groups (P＞0.05).However,the AHD,AI,LAA and acromial thickness showed statistically significant difference between the patients group and control group (all P＜0.05).The type Ⅲ acromion was signifi candy different from the other types in patients group (P＜0.05).Conclusion MRI can clearly display RCT.The AHD and LAA are smaller,the AI and acromial thickness are bigger in RCT patients.Type Ⅲ acromion may increase risks for RCT.

Objective To evaluate the feasibility and safety of thoracoscopic radical resection of non-small cell lung cancer(NSCLC)patients under laryngeal mask anesthesia. Methods A total of 40 patients with NSCLC from March to August 2016 in NanFang Hospital of Southern Medical University were recruited and divided into two groups,the laryngeal mask anesthesia(n=20)and the intubation anesthesia group(n=20). Patients from two groups were followed up. Post-operativerecovery ,systemic inflammation response and quality of life were assessed. Results There was no significant difference between the laryngeal mask anesthesia and the intubation anesthesia group in the operation time ,the lowest oxygen saturation ,the maximum end-tidal carbon dioxide partial pressure and the surgical field and the satisfaction of anesthesia and blood loss. Post-operative time to eat ,postoperative use of antibiotics , postoperative hospital stay and drainage time were much shorter in the laryngeal mask anesthesia group ,which also had lowerlevel of white blood cells ,neutrophils and C-reactive protein. Patients with NSCLC undergoing laryngeal mask anesthesia had much higher scores in the quality of life evaluation. Conclusion Thoracoscopic radical resectionunder laryngeal mask anesthesia is safe and feasible for NSCLC patients. It has advantages in reducing the systemic inflammatory response ,accelerating the recovery rate and improving postoperative life quality.

Objective To explore the diagnosis,treatment and prognosis of primary gastric malignant (lymphoma)(PGML).Methods The diagnosis and treatment data of 21 cases of PGML admitted in our(hospital) during 8 years was retrospectively analyzed.The diagnostic methods included barium meal(examination),gastroscopy,B type ultrasonography,and CT scan.All patients underwent operative treatment and most of the patients received adjuvant chemotherapy.Results Upper abdominal pain,digestive tract bleeding,emaciation and abdominal mass were common clinical manifestations of PGML.The resectabilty rate of PGML was 90.5% while the 5-year survival rate was 57.1%.Conclusions The key to a satisfactory prognosis was early diagnosis,radical curative operation and combined treatment.

Objective To investigate the expression and activity of transforming growth factor-β1 (TGF-β1)and endothelial nitric oxide synthase(eNOS) in the cavernous vascular structural remodeling of diabetic rats.Methods 52 adult male SD rats were randomly assigned to experimental group(DM) and control group(NDM).In DM group,diabetes was induced in rats 4 days after intraperitoneal injection with streptozotocin.HbA1c was measured on 2,4,8,and 16 weeks after injection.Penile tissues were harvested.The protein expression of TGFβ1 and eNOS in situ was evaluated by the Envision immunohistochemistry.Results Compared to NDM group,the expression of the HbA1c increased significantly in DM group on the 16th week(P ＜0.01),both the penile erection rate and penile erectile times decreased significantly in DM group on the 16th week (P ＜ 0.01),and the value of eNOS decreased on the 16th week(P ＜0.01).The expression of TGF-β1 went up in DM group compared to NDM group on the 8th week (P ＜ 0.01) and sustained to the 16th week (P ＞ 0.05).In DM group,we found that TGF-β1 protein in cavernous body of penis was positively related with age in weeks(r =0.947,P ＜0.01) ; and eNOS in cavernous body of penis was negatively related with age in weeks (r =-0.945,P ＜ 0.01).Meanwhile,the expression of TGF-β was negatively related with the eNOS(r =-0.891,P ＜0.01).Conclusion Our results indicate that TGF-β1 plays an important role in the pathogenesis of diabetic erectile dysfunction(ED) and TGF-β1 inhibition may be a promising strategy to prevent development of diabetic ED.

OBJECTIVETo analyze the relationship between Chinese medical constitutions and chemotherapy-induced leucopenia (CIL) of primary breast cancer patients.

METHODSTotally 306 breast cancer patients undergoing adjunctive chemotherapy for the 1st time, and effective 291 breast cancer patients were recruited in this study.Nine Basic Constitutional Scale was used before first chemotherapy. Chinese medical constitutions were classified and quantitatively scored. The highest grading for any item of adverse reactions in each case during the whole chemotherapy course was recorded after chemotherapy. Data were statistically analyzed using SPSS16.0.

RESULTSThere was no significant difference in CIL between different chemotherapy regimens and various Chinese medical constitutions of breast cancer patients (P > 0.05). Yang deficiency constitution is one risk factor for CIL. The higher the score of yang deficiency constitution, the more severe the CIL.

CONCLUSIONSYang deficiency constitution was correlated with the degree of CIL. The higher the score of yang deficiency constitution, the greater the risk of III-IV grade CIL in breast cancer patients.

A new flavonoid glycoside, (-)-2S-8-methyl-5,7,4'-trihydroxyflavanone-7-O-β-D-glucopyranoside (1), along with five known ones, quercetin-3-O-(2"-galloyl)-α-L-arabinoside (2), kaempferol-3-O-α-L-arabinoside (3), guaijaverin (4), trifolin (5) and hyperin (6), was isolated from the leaves of Eucalyptus robusta. Their structures with absolute configurations were elucidated by NMR, HR-ESI-MS, CD spectra data and physicochemical methods. In addition, 2-6 were isolated from E. robusta for the first time.

The traditional fermentation engineering experiment requires a reform on the experimental con-tents and teaching pattern. According to the production process of industrial enzymes, we set up a two-week comprehensive experiment. The students designed and prepared the experiment by themselves. Moreover, the pattern of self-management was used in the process and the experiment scores included the self-assess-ment and objective assessment. It was proved that the new teaching pattern increased the study interesting of students, inspired their initiative and trained their spirits of team cooperation. The teaching effect was im-proved markedly and good ideas are also put forward to solve the possible problem.
