Objective To observe the effect of Wenxin granule combined with Paroxetine in the treatment of the elderly patients with depression after fracture.Methods 80 patients with depression after fracture were randomly divided into a control group and a study group(n=40 cases,per group),and both groups were treated with the conventional treatment. On this basis, the control group was treated with Paroxetine,while the study group was treated with Wenxin granule combined with Paroxetine. The HAMD score and HAMA score were detected in the patients before the treatment and 4 and 8 weeks after the treatment separately.Results Before the treatment,there was no statistical significance in HAMD and HAMA score(t=0.512, 0.520,P>0.05). After treated for 4 and 8 weeks,compare with the control group,both HAMD score(t=1.828, 2.259,P<0.05) and HAMA score(t=1.819, 2.261,P<0.05) were decreased in the study group. After treatment for 4 and 8 weeks, compare with the control group, the total efficiency showed in the HAMD reduction rate of the study group was better(χ2=3.203, 4.370,P<0.05).Conclusions Wenxin granule combined with Paroxetine can significantly decrease HAMD and HAMA score,obviously improve the depression symptoms in the elderly patients with depression after fracture.

Effects of endomorphin-1 (EM-1) and endomorphin-2 (EM-2) on synaptic transmission were investigated on neurons in substantia gelatinosa (SG) of the spinal dorsal horn by whole-cell voltage clamp recording. Both EM-1 (1 μmol/L) and EM-2 (1 μmol/L)remarkably reduced the frequency but not the amplitude of miniature excitatory postsynaptic currents (mEPSCs) and miniature inhibitory postsynaptic currents (mIPSCs). These effects were antagonized by 3-funaltrexamine ( β-FNA, 10 μmol/L), a selective μ-opioid receptor antagonist. Noticeably, EM-1 showed higher potency in decreasing the frequency of mEPSCs and mIPSCs than that of EM-2. These results indicate that EMs suppress both excitatory and inhibitory synaptic transmission by activating presynaptic μ-opioid receptors in the SG and EM-1, compared with EM-2, might be a more potent endogenous analgesic at the spinal cord level.

In recent years, many modern spectral databases for complex materials ( such as soil, feed, forensic evidence materials, pharmaceuticals and oils) have been established based on molecular spectroscopy (UV, infrared, near infrared, Raman and fluorescence) both at home and abroad, which are playing more and more important roles in the agricultural and industrial production and science research. Spectral searching method is one of the key technologies to make full use of the molecular spectral database. This paper reviewed the progress in the basic and modified algorithm, strategy and application of molecular spectral searching methods, and put forward the scientific and technological problems that need attention and further research.

Objective To observe the clinical curative effect of Huoxue-Zhitong decoction combined with mannitol in the treatment of swelling and pain after operation of tibiofibular fracture. Methods 86 patients with swelling after the operation of fracture of tibia and fibula were randomly divided into two groups, with 43 cases in each group. The observation group was treated with intravenous rapid infusion of mannitol, the control group was treated with Huoxue-Zhitong decoction combined with intravenous rapid infusion of mannitol. Swelling, pain visual analogue scale (VAS) score of limb of patients at 1 D and 10 d after operation, time of detumescence and acesodyne and the total efficiency of the treatment between the two groups were compared. Results The indices of the two groups mentioned above at 7 d after the operation significantly decreased, the value in the observation group was lower than the control group (1.3 ± 0.7 cm vs. 1.9 ± 0.9 cm, t=3.451; 1.5 ± 0.6 points vs. 1.9 ± 0.7 points, t=2.845; all P<0.01); The detumescence and acesodyne time of the observation group was shorter than those of the control group (8.6 ± 1.7 d vs. 9.8 ± 2.3 d, t=2.751; 5.5 ± 1.4 d vs. 6.7 ± 1.7 d, t=3.573; all P<0.01), the total efficiency in the observation group was superior to the control group, there were statistically significant differences (97.7% vs. 83.7%; χ2=4.961, P=0.026). Conclusions Huoxue-Zhitong decoction combined with mannitol is effective and safe in the treatment of swelling and pain after operation of tibiofibular fracture.

CONCLUSION: The method is simple with strong specificity and good reproducibility, and can be used as the quality control of this preparation.

BACKGROUND: Injectable artificial bone composite has been reported to consider as a moulding filler of vertebrae at the histology level; however, the therapeutic effect needs to be further studied at the level of axial pressure capacity. OBJECTIVE: To explore the axial pressure capacity of dogs with thoracolumbar fractures treated by injectable artificial bone composite. DESIGN, TIME AND SETTING: A randomized controlled animal experiment was performed at the Animal Laboratory of Shenzhen Longgang Central Hospital from September 2008 to January 2009. MATERIALS: Type I and type II vertebral pedicle screw systems were provided by Tianjin Zhengtian Medical Device Company Limited; injectable artificial bone composite, which was made of coral-hydroxylapatite compound, recombinant human bone morphogenetic protein-2 (Academy of Military Medical Sciences), and 2% chitosan solution (the Second Military Medical University of Chinese PLA and Shanghai Qisheng Biomaterials Institute), was manufactured according to the methods provided by Yin et al. METHODS: A total of 20 1-year-old healthy dogs were randomly divided into treatment and control groups with 10 dogs in each group. The model of those dogs with thoracolumbar fractures was made by imitating falling accidents; thereafter, the dogs in the treatment group were treated with vertebral pedicle screw system internal fixation and vertebroplasty by filling the injured vertebrae with injectable artificial bones. The control group was treated with vertebral pedicle screw system internal fixation alone. MAIN OUTCOME MEASURES: The maximum pressure intensity of injured vertebra, upper and lower vertebra at vertebral body center was detected using micro-computer pressure testing system after three months. RESULTS: The maximum pressure intensity at vertebral body center was not significant differences in the treatment group (100% cases) between injured vertebral body and its neighboring vertebral body, and axial loading was recovered. While that of 60% cases in the control group was significantly different (P
