Objective To analyze the risk factors for traumatic cerebral venous sinus occlusion (CVSO)and to investigate the strategies of early diagnosis of traumatic CVSO. Methods The clinical data of 212 patients with moderate to severe closed traumatic brain injury from January 2012 to December 2015 were analyzed retrospectively. Logistic regression analysis was used to evaluate the risk factors for traumatic CVSO. Results Of the 212 patients with traumatic brain injury, 16.5%(35/212) patients had CVSO. Ten patients had CVSO of thrombotic type (typeⅠ), 16 patients had CVSO of compression type (typeⅡ), and 9 patients had CVSO of mixed type (typeⅢ). Logistic regression analysis showed that skull fracture (OR = 8.141; 95%CI: 3.224-20.840) and epidural hematoma of crossing venous sinus (OR = 3.179; 95%CI: 1.470-7.037) were the risk factors for CVSO, and the former was more significantly correlated with CVSO. Female gender was the risk factor for CVSO typeⅠ(OR =10.425; 95%CI: 1.831-30.053), epidural hematoma of crossing venous sinus was the risk factor for CVSO typeⅡ(OR = 5.766; 95%CI: 1.885-18.197), and skull fracture, epidural hematoma of crossing venous sinus, and the previous history of vein thrombosis was the risk factors for CVSO type Ⅲ(OR =18.005, 4.596, 11.394; 95%CI: 2.021-58.836, 1.144-19.525, 1.436-46.558). Conclusions In the early diagnosis of traumatic CVSO, the crossing venous sinus fracture line and epidural hematoma should be given attention. Attention should be paid to the history of venous thrombosis. MR venography and CT venography contributes to early diagnosis of CVSO.

BACKGROUND: Moxibustion can improve the symptoms of rheumatoid arthritis and reduce inflammation, but there are no uniform operation standards. The moxibustiondistance becomes one of factor influencing the therapeutic efficacy.OBJECTIVE: To compare the effects of different moxibustion distances on rheumatoid arthritis, and to explore the optimal distance.METHODS: The 8 of 40 male Sprague-Dawley rats were randomlyselected as controls. The other 32 were used to make animal modes of collagen type Ⅱ-induced ankle arthritis, and then given moxibustion at Shenshu (BL23) and Zusanli (ST36) at an interval of 1, 2 and 3 cm, respectively, once daily, 10 minutes at each point, 6 days per course for three courses, with a course interval of 1 day. Model rats with no treatment acted as model group.RESULTS AND CONCLUSION: Compared with the control group, the toe volume, arthritis index and serum levels ofinterleukin-1β and tumor necrosis factor-α except the body mass were significantly increased in the model group (P < 0.01).After moxibustion treatment, these indexes were significantly decreased in the three treatment groups (P < 0.01), especially in the 1 and 2 cm groups (P < 0.01). Narrowed articular cavity, intra-articular inflammation and pannus formation were observed in the model group, while only moderate inflammatorycell infiltration and few pannus formation were found in the 1,2, 3 cm groups. These results indicate that moxibustion improvesjoint functions and regulates immune reaction by downregulating the levels of interleukin-1β and tumor necrosisfactor-α, as well as reducing synovial hyperplasia. In addition,the optimal distance for moxibustion is 1 or 2 cm, which is amomentous proposition to improve therapeutic efficacy.

Objective: To observe the effect of different moxibustion durations on rats with rheumatoid arthritis (RA) and to evaluate the relationship between moxibustion amount and moxibustion efficacy.Methods: Eight rats were randomly selected as a normal group from the 40 male Sprague-Dawley (SD) rats, and the other 32 rats were used to establish typeⅡ collagen-induced RA models. After successful modeling, the 32 rats were randomly divided into a model group, a moxibustion for 20 min group, a moxibustion for 40 min group and a moxibustion for 60 min group, with 8 rats in each group. Rats in the normal group did not receive modeling and moxibustion intervention; rats in the model group did not receive moxibustion after modeling; rats in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group were treated with moxibustion at Shenshu (BL 23) and Zusanli (ST 36) for 20 min, 40 min and 60 min, respectively. Six days were a course of treatment, with a total of 3-course treatments and a 1-day rest between the courses of treatment. After treatment, the serum levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, arthritis index (AI) scores, toe volumes and pathological score of synovitis were evaluated in the rats.Results: Compared with the normal group, the serum IL-1β and TNF-α levels, and the toe volumes in the model group were increased, and the differences were statistically significant (P<0.01), before the treatment. Compared with the model group, the serum IL-1β and TNF-α levels, toe volumes and arthritis index (AI) scores were significantly decreased in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group (P<0.05 orP<0.01 ). Compared with the moxibustion for 20 min group and the moxibustion for 60 min group, serum IL-1β and TNF-α levels, toe volumes and AI scores were decreased more significantly in moxibustion for 40 min group, and the differences were statistically significant (P<0.05 orP<0.01). There were no significant differences in serum IL-1β and TNF-α levels, AI scores and toe volumes between the moxibustion for 20 min group and the moxibustion for 60 min group (allP>0.05). The synovial histopathological improvement was the most obvious in the moxibustion for 40 min group, when the synovial histopathological changes were compared among the moxibustion for 20 min group, moxibustion for 40 min group and moxibustion for 60 min group.Conclusion: The therapeutic efficacy of moxibustion for 40 min in RA rats was more significant than that of moxibustion for 20 min and moxibustion for 60 min, indicating that the duration of moxibustion is the main factor affecting its therapeutic efficacy.

BACKGROUND: Silk fibroin derived from silk had a good biocompatibility and biodegradation, which could be used for biomaterials to improve cell adhesion and growth abilities. OBJECTIVE: To investigate the efficacy of silk fibroin/hydroxyapatite (SF/HA) compounded of adipose-derived stromal cells (ADSCs) on repairing bone defects. METHODS: Adipose tissues were derived from epididymis of 2-month-old New Zealand rabbits and trypsogen-passaged to obtain ADSCs. The third-passage ADSCs at the concentration of 1×10/L were placed on SF/HA scaffold. Three hours later, the composite was cultured with DMEM culture media containing 1 μmol/L dexamethasone, 50 μmol/L vitamin C, and 10 mmol/L β-sodium glycerophosphate. Thirty-six rabbits were induced cancellated bone defect sizing 4.5 mm × 4.5 mm × 10 mm. The composite group was implanted with SF/HN/ADSCs scaffold, the simple group was implanted with SF/HA scaffold, but any treatment was employed in the blank control group. RESULTS AND CONCLUSION: At 12 weeks, general observation demonstrated that the bone defects were repaired entirely in composite group and partly in simple group. However, the bone defect was not repaired in the blank control group. X-ray and histological observation suggested that at 12 weeks the bone defects were repaired entirely in composite group and partly in simple group. The quantity of the newly formed bone in the composite group was significantly more than that in the simple group (P < 0.05). Repair showed no effect in the blank control group. SF/HA/ADSCs composite could successfully repair bone defects of a rabbit femur, and the effect was superior to SF/HA scaffold.

Objective To investigate the efficacy and safety of domestic exenatide injection versus imported exenatide injection in type 2 diabetic patients with inadequate glycemic control on monotherapy or combination therapy of metformin and insulin secretagogues. Methods A multicenter, randomized, parallel-controlled, and non-inferiority trial was carried out. A total of 240 subjects were randomized at a 1:1 ratio to add domestic exenatide injection (trial group) or imported exenatide injection (control group) on the background therapies. The primary endpoint of efficacy was HbA1C change from baseline to week 16. The secondary endpoints of efficacy were the proportion of HbA1C<7.0%, and the changes in fasting plasma glucose (FPG), 2 h plasma glucose after standard meal (2hPG), 7-point self monitoring of blood glucose (7P-SMBG), and body weight from baseline to week 16. Results Among subjects of per-protocol sets, adjusted mean HbA1C reduction was -1.07% in the trial group versus -1.06% in the control group after 16 weeks of treatment. The lower boundary of the two-sided 95% confidence intervals of the mean HbA1C reduction difference between the trial and control groups was -0.29%, which was more than -0.35%, suggesting that the predefined statistical criterion for non-inferiority was achieved. The proportions of subjects achieving HbA1C<7.0% at the end of the 16-week treatment were 56.19% and 54.08% in the trial and control groups, respectively (P>0.05). The changes in FPG, 2hPG, 7P-SMBG and body weight from baseline to week 16 were comparable between the two groups (all P>0.05). Moreover, the incidences of hypoglycemia and adverse events were similar between the two groups (both P>0.05). Conclusion In type 2 diabetic patients inadequately controlled by monotherapy or combination therapy of metformin and insulin secretagogues, the efficacy of cotreatment with domestic exenatide injection is not inferior to that of imported product ones, with a similar safety profile.
