Yanghe decoction attenuated pain hypersensitivity induced by michigan cancer foundation-7 injection in rats with bone metastases from breast cancer by inhibiting transient receptor potential ankyrin 1.

OBJECTIVE: To study the effect and underlying mechanisms of Chinese medicine Yanghe decoction on pain relief in a rat model of bone metastasis of breast cancer induced by michigan cancer foundation-7 (MCF-7). METHODS: Bone pain was induced in the tibia of rats injected with MCF-7 cells. The Chinese herbal remedy was used to decoct Yanghe decoction for the treatment of bone pain rats. The behavior study was carried out to evaluate the paw mechanical withdraw threshold and thermal withdraw latency. Liquid chromatography-mass spectrometry, Western blotting, quantitative real-time polymerase chain reaction, enzyme-linked immunosorbent assay (ELISA), immunohistochemical (IHC) staining were performed for analysis. RESULTS: Yanghe decoction could improve the defensive behavior similar to the transient receptor potential ankyrin 1 (TRPA1) inhibitor. In morphology study, Yanghe decoction could attenuate the cellular growth as well as inflammatory infiltration in the metastasis group. Furthermore, Yanghe decoction downregulated the TRPA1 expression on the dorsal root ganglion from the metastatic rats at both transcriptional and protein level. Yanghe decoction alleviated the inflammation in metastatic tissues by hematoxylin-eosin and IHC analysis, and Yanghe decoction also reduced the inflammatory cytokines production in the serum including tumor necrosis factor-α and interleukin-6, interleukin-1 beta by ELISA. As the cytochromec oxidase subunit II/prostaglandin E2 (PGE2) is required for cancer development, Yanghe decoction reduced the expression of PGE2 in the tissue and serum. CONCLUSION: Taken together, Yanghe decoction protected the rats from breast cancer bone metastasis through TRPA1 signaling mediated neuropathic pain and additional immune modulation in tumor microenvironment.

Clinical observation of tuina manipulations for tic disorders in kids / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of tuina manipulations in treating different types of tic disorders (TD). Methods: Eligible TD patients were classified into three types, transient tic disorders (TTD), chronic multiple tic disorders (CMTD) and Tourette syndrome (TS), according to their disease duration and severity. The three types of children were treated with the same tuina manipulations. Changes in the Yale global tic severity scale (YGTSS) score, effective rate for tic, and cervical spine imaging examination results (including asymmetry of the lateral atlanto-dental interval, broadened anterior atlanto-dental interval, C2 spinous process deviation, occipito-atlanto-axial flexion/ extension instability) were observed after 1-month and 3-month treatments respectively. Results: The YGTSS score changed significantly after 1-month and 3-month treatments compared with that before treatment (both P<0.01); the effective rate for TD was 46.6％ and 86.7％ respectively after 1-month and 3-month treatments; there were significant differences comparing the effective rate for tic between different types of TD after 1-month and 3-month treatments (all P<0.05); comparing the effective rate for tic after 1-month treatment with that after 3-month treatment for the same type, the intra-group differences were statistically significant [TTD group (P<0.01), CMTD group (P<0.01), TS group (P<0.05)]; the abnormal parameter rates in neck imaging examination after 3-month treatment were significantly different from those before treatment (all P<0.01). Conclusion: Tuina manipulation is effective for TTD, CMTD and TS. It can correct the abnormal alterations of patients' cervical vertebrae, and its efficacy for TTD is most significant.

Limited external fixation of plastic cardboard for the treatment of senile comminuted humeral fracture / 中国骨伤

OBJECTIVE@#To explore clinical efficacy of limited external fixation with plastic paperboard in treating senile proximal comminuted humeral fracture.@*METHODS@#From June 2015 to December 2017, 32 senile patients with proximal comminuted fracture of humerus were treated with plasticized cardboard after manual external fixation. Among them, including 13 males and 19 females aged from 55 to 85 years old with an average of(68.22±8.36) years old; 18 patients on the left side and 14 patients on the right side; all patients were regularly review shoulder X-rays and performed appropriate functional exercises. Constant-Murley shoulder joint scoring was used to evaluate clinical effects.@*RESULTS@#Thirty-two patients were followed up for 3 to 12 months with an average of (4.97±2.39) months. All patients were underwent functional exercise under guidance of physicians. Nine patients were treated with topical Chinese herbal moist heat compresses to promote shoulder function recovery. Thirty-one patients were obtained fracture healing, the time ranged from 5 to 12 weeks with an average of(7.44±1.72)weeks. One patient was not healed due to comminuted fracture of fracture end and the separation was large, the blood supply to humeral head was insufficient for necrosis absorption. Postoperative Constant-Murley shoulder score at 3 months was 87.56±6.93; 15 patients got excellent results, 14 good, 2 fair and 1 poor.@*CONCLUSIONS@#Limited external fixation with plastic paperboard for the treatment of senile proximal comminuted humeral fracture could ensure biomechanical stability of fracture, promote early recovery of shoulder joint function and shorten recovery time.

Application and prospect of fungi elicitors in fermentation industry / 生物工程学报

Fungal elicitors are a group of chemicals that can stimulate the secondary metabolite production in plants and microbial cells. After being recognized, it could enhance the expression of related genes through the signal-transduction pathway; regulate the activity of the enzyme involved in the biosynthesis of secondary metabolites. In recent years, the inducible mechanism of fungal elicitors has been studied deeply worldwide. Meanwhile, it has acquired wide concern in the area of biological industry, especially in the fermentation industry. This paper addresses the application and prospect of fungal elicitors in the secondary metabolites of plant and microbial cells.

Protective role of MMP-9 inhibitor batimastat in acute lung injury after cardiopulmonary bypass / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the protective effect of exogenous inhibitor of matrix metalloproteinases-9 (MMP-9), batimastat, in the lung injury induced by cardiopulmonary bypass (CPB) in dogs.</p><p><b>METHODS</b>Thirty healthy mongrel puppies were randomly divided into 3 groups: control group, low-dose group [batimastat 10 mg/(kg.d) for 3 days before operation] and high-dose group [batimastat 30 mg/(kg.d) for 3 days before operation]. The off-pump puppies' model of acute lung injury was established, and hemodynamic and respiratory parameters were monitored. The preoperative and postoperative alveolar-arterial oxygen difference (A-aDO(2)) and respiratory index (RI) were calculated. From the beginning of surgery, blood samples were taken at the time 0, 60, 120, and 270 min. Plasma concentrations of MMP-9 were measured by ELISA, and blood MMP-9 mRNA expressions were determined by RT-PCR. The myeloperoxidase (MPO) activity of centrifugal bronchoalveolar lavage fluid were measured by Colorimetry. And MMP-9 activity was determined by Gelatin zymography. Light and electronic microscope were used to observe the morphological changes of lung tissue. A small piece of left lung tissue was taken, weighed and baked to calculate the wet weight (W/D) index.</p><p><b>RESULTS</b>After cardiopulmonary bypass, the concentrations of MMP-9 and mRNA expressions of the control group were increased significantly, and lung injury was apparent. At 270 min, the MMP-9 plasma concentration of high-dose group (17.36 +/- 1.18) microg/L was significant reducing than control group (30.47 +/- 2.22) microg/L (P < 0.05). After operation, A-aDO(2) and RI of high-dose group were significantly improved than control group (P < 0.05). The W/D index of the high-dose group (2.8 +/- 0.48) was significantly lower than that of control group (4.7 +/- 0.6) (P < 0.05). And the pathological changes of lung tissue were significantly improved in the high-dose group. However, there was no significant difference in the MMP-9 mRNA expression in three groups.</p><p><b>CONCLUSIONS</b>Batimastat plays a role in the protection of the lung injury of CBP by reducing the concentration and activity of MMP-9, the degradation of the cell membrane and pulmonary neutrophil infiltration and reduction of pulmonary edema.</p>
