Neurodegenerative disease is characterized by progressive loss of neurons in specific brain regions that results in neuronal dysfunction of the central nervous system. Although the pathological mechanism is not fully established, the activation of glial cells mediated neuroinflammation appears to be involved. Heat shock protein 70 (HSP70) is originally described as intracellular chaperone, which plays an important role in protein quality control in cells. However, recent study showed that up-regulation of HSP70 had anti-inflammatory effects in the brain. HSP70 protected neurons from damage and improved neurological function by decreasing inflammatory response as indicated by inactivation of glial cells and inhibition of pro-inflammatory cytokine release. So it is of great significance to find new compounds targeting at HSP70 as neuroprotective agents to delay the progress of neurodegenerative disease. This review will focus on the role of HSP70 in neuroinflammation and the recent advances in using HSP70 as a target for the treatment of neurodegenerative disease.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.

8. Research status on prevention and treatment of traditional Chinese medicine on focal segmental glomerulosclerosis
Chinese Traditional and Herbal Drugs 2018;49(19):4688-4693
Focal segmental glomerulosclerosis (FSGS) is a common glomerular disease, and nephrotic syndrome is the main clinical manifestation. The prognosis of the kidney is mainly related to proteinuria severity, renal function, and drug response. The use of chemical drugs such as hormones and immunosuppressants is not effective in the treatment of some FSGS patients, and the side effects are obvious. In recent years, with the in-depth research on the treatment of FSGS by traditional Chinese medicine and the proof of clinical efficacy, traditional Chinese medicine has great advantages in delaying glomerular sclerosis and reducing the side effects of chemical drugs. The present situation of Chinese medicine treatment in FSGS is reviewed in this paper.

The kinetics of batch and fed-batch cultures of recombinant Escherichia coli to produce humanlike collagen were investigated. Through examining the density of substrate and the amount of mushrooms and the density of products during the process of fermenting, a set of kinetic models are set up. The influence of cell without plasmid was considered. The results show that the kinetic model may well simulate the fermenting process.

Objective To summarize the contrast enhanced ultrasonographic (CEUS) features of benign focal liver lesions, on and to investigate the value of contrast enhanced ultrasound techniques in the diagnosis of benign focal liver lesion. Methods The contrast enhanced ultrasonographic performance of 68 benign focal liver lesions cases which were dififcult for routine ultrasound diagnosis and conifrmed by pathology or follow-up were retrospectively analyzed. Chi-square test of four-fold table were used to compare the diagnostic coincidence rate of conventional ultrasound and contrast-enhanced ultrasound. Results The 68 cases of benign focal liver lesions included complex cysts (n=7), liver hydatids (n=2), liver abscess (n=15), focal nodular hyperplasia (n=8), angiomyolipoma (n=2), hepatocellular adenoma (n=4), focal fat accumulation (n=16), inlfammatory pseudotumor (n=12), solitary necrotic nodule (n=1), intrahepatic biliary cystadenoma (n=1). There were no enhancement among 7 complex cysts, 2 liver hydatids and 1 solitary necrotic nodule. Isoenhancement was detected in focal fat accumulation (n=16);hypoenhancement during the arterial phase and sustained enhancement during the portal or late phase was found in focal nodular hyperplasia (n=8) and angiomyolipoma (n=2). Grid-like enhancements during the arterial phase and isoenhancement or hypoenhancement during the portal phase, and hypoenhancement during the late phase was presented in liver abscess (n=15). Hyperenhancement during the arterial phase were detected in 4 cases of hepatocellular adenoma, 3 of which showed isoenhancement or hyperenhancement during the portal and delayed phase, one case showed hypoenhancement during the portal phase. Eight cases of all the inlfammatory pseudotumor showed no enhancement during all phases;3 cases showing grid enhancement during the arterial phase and the enhancement washed out rapidly;1 case showed mild edge enhancement during the arterial phase and hypoenhancement during the delayed phase. The solid part of the intrahepatic biliary cystadenoma showed hyperenhancement during the arterial phase and hypoenhancement during the portal and late phase.The central area showed no enhancement during all phase. The coincidence rate between pathology and conventional ultrasound diagnosis was 61.8%(42/68). The coincidence rate between pathology and contrast- enhanced ultrasound diagnosis was 92.6%(63/68). The coincidence rate of contrast-enhanced ultrasound diagnostic was higher than that of conventional ultrasound, with a statistically signiifcant difference (χ2=8.17, P < 0.01). Conclusion Real-time gray-scale contrast-enhanced sonography can improve the accuracy of the diagnosis and differential diagnosis for benign focal liver lesions.
