ObjectiveTo observe the therapeutic effect and prognosis of nimodipine on severe traumatic brain injury. Methods64 patients with severe traumatic brain injury were divided into the nimodipine group(32 cases) and the routine treatment group(32 cases). The Glasgow Coma Scale(GCS) was assessed before and after the treatment. The Activities of Daily Living(ADL) and cognitive ability were evaluated in clear-headed patients. After 6 months follow-up, the Glasgow Outcome Scale (GOS), Bathel index and Mini Mental State Examination (MMSE) score were carried on.ResultsIn both of the two groups, GCS score were increased distinctively after treatment. The MMSE score in nimodipine group was higher than that of routine treatment group. There was no statistic difference in GOS and ADL between two groups after 6 months, but MMSE in nimodipine group was higher than that of routine treatment group. Conclusions Nimodipine could be helpful in cognitive function. The prognosis of severe traumatic brain injury lied on the degree of cerebral damage.

AIM:To evaluate the efficacy and safety of large sized continuous curvilinear capsulorhexis ( CCC ) involving zonular area in manual small incision cataract surgery ( MSICS) .
METHODS:Totally 1 443 cataract patients ( 1 965 eyes ) underwent MSICS, in which large CCC up to 7-8mm were performed . The related conditions such as success rate of performing CCC, capsule rupture, corneal edema and visual acuity after surgery were recorded and statistically analyzed.
RESULTS:In total of 1 965 eyes, 1 942 eyes ( 98. 83%) had successful CCC, 15 eyes (0. 76%) had a radial tear which could not be saved when performing CCC, 8 eyes (0. 41%) had anterior capsule opened with a cystotome or a scissor due to capsule membrane calcification. No posterior capsule rupture occurred, and intraocular lens was transplanted in all cases. Transient corneal edema was noted in 36 eyes (1. 83%). One day after surgery, 1650 eyes (83. 97%) had visual acuity ≥0. 5, 1867 eyes (95. 01%) ≥0. 3. No unstable intraocular lens was noted in all cases.
CONCLUSION:Large CCC technique for MSICS is safe and reliable, not decreasing stability capsular bag and intraocular lens. It is of high originality despite zonular area is involved so that it is worthy of application in basic medical institutions.

BACKGROUND:In clinical application, the structure of crista lambdoidalis of L5 was unclear. It needs to expose more tissue to define L5 entry point through transverse process or superior and inferior articular process. This increased the risk of trauma and iatrogenic superior intervertebral degeneration. Therefore, it is necessary to expose L5 entry point with a minimaly invasive way. OBJECTIVE:To investigate the accuracy of L5 pedicle screw insertion with the entry point of mastoid process slope by imaging. METHODS:Mastoid process was located on the base of L5 superior articular process. A cant was formed when the highest point of L5 mastoid process backward protuberance extended inwards and downwards. The cant was defined as mastoid process slope; it was lateral to pedicle medial superior side internaly, medial to transverse process root and superior to the top of crista lambdoidalis. The slope was first easily touched and exposed in lumbar posterior surgery through paraspinal muscle space approach. Fifty patients of lumbar spine disorders were treated by L5 pedicle screws fixation through the entry point of mastoid process slope. According to preoperative radiographic and CT images, pedicle screw insertion direction of the sagittal and transverse sections was calculated. The diameter of pedicle screw was 6.5 mm. The condition of intraoperative successful rate of screws placement at one time was analyzed. The accuracy of screw placement was evaluated by postoperative radiographic and CT images. RESULTS AND CONCLUSION:With the method of the mastoid process slope, the successful rate of screw placement at one time was 96% (96/100). Totaly 100 screws were inserted into L5. According to the criterion by Gertzbein, 95 screws (95%) totaly located in pedicles and 5 screws (5%) encroached on the pedicle from medial wal. Three (3%) out of 5 inaccurately placed screws cut out less than 2 mm of the inner wal, while 2 (2%) between 2 mm and 4 mm, without neurologic deficits. The method of mastoid process slope had a high successful rate of screw placement. Combined with preoperative X-ray films and CT images could obtain a high accuracy rate of screw insertion.

AIM: To explore the curative effect of methylprednisolone with octreotide retrobulbar injection therapy on thyroid associated ophthalmopathy.
METHODS:Fifty- one cases ( 96 eyes ) with thyroid associated ophthalmopathy were treated with methylprednisolone ( 500mg/d ) for 3d, and then retrobulbar injection of octreotide (0. 1mg/mo) for 3mo in one course. Symptoms and signs of the patients were observed before and after the treatment course.
RESULTS: Symptoms of 49 cases were improved significantly. In all cases, the mean value of exophthalmus of the patients was significantly decreased after the treatment by 3. 1 ± 1. 4mm. The height of palpebral fissure was significantly decreased after the treatment by 2. 4 ± 0. 9mm, there were statistically significant difference before and after treatment (P<0. 05).
COCLUSION: Methylprednisolone with octreotide retrobulbar injection therapy can improve symptoms and signs of the patients with thyroid associated ophthalmopathy with high safety and no obvious side effect.

Psoriasis is an immune-abnormal, chronic, proliferative skin disease determined by polygenic inheritance and induced by a number of environmental factors. It causes worldwide concern because of its high-prevalence, harmful and incurable characteristics. Over the years, Chinese medicine (CM) treatment of psoriasis has accumulated a wealth of clinical experience. Disease-syndrome combination, which achieves more satisfactory clinical effect, is the basis to highlight the special CM advantages in treating psoriasis. In this paper, we review the advantages of treating psoriasis with the combination of disease and syndrome, analyze the prospects of research on treating psoriasis combining disease with syndrome. We also make a point that there are several key points for the clinical research of combination of disease and syndrome. It can be expected that carrying out clinical research on the combination of disease and syndrome will help improve the clinical efficacy of medical treatment of psoriasis, which will be the main direction of research in the future.

Objective To characterize the immunogenicity in gene immunization of the conserved regions of hepatitis C virus(HCV) based on different delivery strategies. Methods We first constructed a novel DNA vaccine encoding a fusion gene(from partial NS3 and Core) of HCV. Then we compared different protocols based on naked DNA injection twice or DNA injection with gene electrotransfer(GET) in BALB/c mice. The immune response was measured by antibody ELISA and by IFN-gamma ELISPOT. Results Our data showed that a protocol based on intradermally injection of DNA with optimal GET induced the strongest humoral and cellular immunity, and DNA with GET induced a substantially higher anti-NS3/Core T cell re-spoase than naked DNA injection. Conclusion Our data suggest that DNA vaccines encoding NS3/Core fu-sion protein of HCV immunized by the present strategy could merit further study in the context of future prophylactic and therapeutic HCV T cell based vaccines.

OBJECTIVE This study was designed to evaluate the effect of berberine on CUMS induced depression animal model and investigated the underlying mechanisms.METHODS We estab-lished CUMS depressant rat model and treated CUMS rats with berberine.Sucrose preference,forced swim test(FST)and tail suspension test(TST)were used to measure behaviors change.We used Q-PCR and western blot to test the levels of cytokines in the hippocampus. RESULTS We found that CUMS rats displayed obvious depressive like behaviors,moreover,berberine treatment prevented depressive behaviors in CUMS rats accompanied with suppression of oxidative stress markers. Further experi-ments showed that berberine treatment up-regulated the expression of Keap1-Nrf2 antioxidant signaling pathway and its downstream neuroprotective factors. CONCLUSION Our present results suggested that treatment of berberine significantly ameliorated depressive behaviors in CUMS rats through enhancing of Keap1-Nrf2 antioxidant signaling pathways in hippocampus.

Objective To observe the changes of cAMP response element binding protein (CREB)/brain-derived neurotrophic factor (BDNF) signaling pathway in the hippocampus of APP/PS1 double transgenic Alzheimer's disease mice, and in-vestigate the effects of Tiaoxin formula on learning and memory. Methods Totally, 54 three-month-old APP/PS1 transgenic mice were randomly divided into model group (n=18), posi-tive control (donepezil) group (n=18) and Tiaoxin formula group (n=18). Another 18 three-month-old C57/BL6 wild mice were chosen as normal group with same strain and same age. All administration groups received rele-vant medicine. Twelve weeks later, Morris water maze test was used to test the behavior. The real-time quantita-tive polymerase chain reaction (RT-qPCR) was used to detect the expression of CREB mRNA and BDNF mRNA in hippocampus. Western blotting was used to detect the expression of phosphorylated CREB (p- CREB) and BDNF in hippocampus. Results Compared with the model group, the escape latency significantly shortened (P<0.01), the percentage of staying time in the quadrant of original platform significantly increased (P<0.05), the expression of CREB mRNA and BDNF mRNA in hippocampus significantly increased (P<0.05), and the expression of p-CREB and BDNF pro-tein in hippocampus significantly increased (P<0.01) in Tiaoxin formula group. Conclusion Tiaoxin formula could improve the spatial learning and memory of APP/PS1 double transgenic mice with AD, which might be related to the up-regulation of CREB/BDNF signaling pathway.
