In this paper, the extraction rate of crude polysaccharides and the yield of polysaccharides from Hippocampus served as test indicators. The comprehensive evaluation indicators were assigned by the R language combined with the entropy weight method. The Box-Behnken design-response surface methodology(BBD-RSM) and the deep neural network(DNN) were employed to screen the optimal parameters for the polysaccharide extraction from Hippocampus. These two modeling methods were compared and verified experimentally for the process optimization. This study provides a reference for the industrialization of effective component extraction from Chinese medicinals and achieves the effective combination of modern technology and traditional Chinese medicine.

Atherosclerosis (AS) is a chronic inflammatory disease associated with high morbidity and mortality. The incidence of AS is increasing in the last decades. So development of safe and effective therapeutics for treating AS has become prominently important. Although there are numerous chemical drugs available for treating AS, some drugs are not effective and some have serious side effects. Traditional Chinese medicine (TCM) has a long history for the prevention and treatment of AS due to its less side effects and superior efficacy. This paper describes the effectiveness and underlying mechanisms for prevention and treatment of AS by TCM or its active components. Some TCM, e.g. XuemaiNing, Tongxinluo and Salvia miltiorrhiza have been reported to have cardio-protective effect. Some active components of TCM, e.g. saikosaponin-A, kuwanon G, luteolin and β-elemene have been isolated from various TCM and demonstrated to have beneficial effects on prevention and treatment of AS.

Dry granulation technology is a great innovation in granulation technology,which saves many intermediate links and reduces many intermediate costs. It is closely related to the characteristics of materials,dry granulation equipment and process. Dry granulation technology is a systematic engineering science covering many technical fields. The process of dry granulation involves complex mathematical model mechanisms of temperature field,pressure field and velocity field,closely related to the characteristics of materials and drying equipment. However,due to the late start of research on dry granulation technology of traditional Chinese medicine,basic research is still weak. The research on dry granulation technology has achieved great results in the fields of food,chemical industry,agriculture and forestry,showing great reference significance. The advantage of dry granulation of traditional Chinese medicine is that it can be directly granulated by adding an appropriate amount of auxiliary materials in the extract powder of traditional Chinese medicine,without the need of wetting,mixing,drying and other processes. The process is simple and can effectively guarantee the quality of traditional Chinese medicine. The granules obtained by the dry granulation technique are important intermediates for preparing the solid preparations of traditional Chinese medicines,which would directly affect the subsequent molding process and the quality of the preparation products. Therefore,based on the characteristics of dry granulation method in traditional Chinese medicine and by referring to the advanced research results of dry granulation technology in other fields,we would discuss the research ideas of dry granulation in traditional Chinese medicine in terms of the mechanism of dry granulation equipment,technology,on-line detection technology and mathematical model of dry granulation process,hoping to provide reference for the research of dry granulation method in traditional Chinese medicine.

AIM To compare the diuretic effects of Descurainiae Semen (DS),Coicis Semen (CS) and Plantaginis Semen (PS),and to observe their mechanical similarities and differences.METHODS Metabolic cage method was applied to investigating the diuretic effects of DS (2.34 g/kg),CS (7.00 g/kg) and PS (3.50 g/kg),whose diuretic mechanisms were studied by cryoscopic method,enzyme method,ion selective electrode method,ELISA and Western blot.RESULTS DS,CS and PS obviously increased saline-loaded rats' urine volume (P ＜ 0.05) and reduced their body weight (P ＜ 0.05) after administration for 7 h,which exhibited no significant effects on urine creatinine (Ucr),serum creatinine (Scr) and blood urea nitrogen (BUN)(P ＞ 0.05).DS showed its diuretic effect mainly by lowering the levels of serum Na +,atrial natriuretic peptide (ANP),brain natriuretic peptide (BNP),pulmonary AQP3,renal AQP1 and AQP2;CS showed its diuretic effect mainly by reducing the levels of serum Na +,Cl-,ANP,pulmonary AQP3,gastric AQP3,renal AQP1 and AQP2;PS showed its diuretic effect mainly by decreasing the levels of serum Na + and Cl-,pulmonary AQP3,gastric AQP3,renal AQP1 and AQP2.CONCLUSION Three medicinal materials have significant diuretic effects without obvious renal harm.DS categorized as a medicinal plant of lung channel and tropism has a great effect on netriuretic peptide system,CS categorized as a medicinal plant of spleen channel and tropism has a great effect on gastric AQP3,and PS categorized as a medicinal plant of renal channel and tropism has a great effect on renal AQPs.

AIM To conduct a metabolic research for a better understanding of nephrogenic edema and to assess the integral efficacy of Mori Cortex in rat model.METHODS The serum creatinine,urea nitrogen,albumin and urinary protein levels in rats were detected.UPLC-QTOF-MS was used to detect the urine metabolites changes,Principal Component Analysis (PCA) and Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA)were used to screen potential biomarkers,after whose quantification,Mev software was adopted for heat map draw-ing and hierarchical cluster analysis.RESULTS The model rats manifested significantly increased levels of serum creatinine,urea nitrogen and urinary protein,decreased albumin level,and an obviously excessive amino acid metabolism as well.The 41 identified biomarkers were mainly related to disturbances in phenylalanine,pyrimidine,arginine and proline,glycine,serine and threonine,tryptophan,cysteine and methionine metabolism,and biosynthesis of pantothenic acid and coenzyme A.A reversal trend in aforementioned levels of biochemical indexes and most biomarkers due to the intervention by Mori Cortex signaled an improvement in the metabolic disorder,renal dysfunction and edema.CONCLUSION The metabolic study demonstrates the pathological status of nephrogenic edema and assesses the effect of Mori Cortex from an overall perspective,highlighting a new approach for illustrating Chinese medical syndrome and the underlying mechanism in the management of traditional Chinese medicine.

OBJECTIVETo investigate the surgical options and clinical effects of delayed osteoporotic vertebral collapse.

METHODSFrom May 2010 to October 2014, 19 patients (20 vertebrae) with delayed osteoporotic vertebral collapse(Kümmell's disease) were enrolled in this study. There were 7 males and 12 females, aged from 65 to 87 years old with a mean of (73.5±5.62) years. According to Li staging system of Kümmell's disease, 3 cases were stage II, 13 cases (14 vertebrae) were stage III without spinal cord injury, 3 cases were stage III with spinal cord injury. Patients were respectively treated with percutaneous vertebroplasty(PVP) or percutaneous kyphoplasty(PKP) on the basis of the degree of postural reduction during operation. Injected cement volume, cement leakage, vertebral height restoration and local kyphotic reduction were observed. Visual analogue scale (VAS) and Oswestry Disability Index(ODI) were respectively used to assess the pain and function before and after operation. Frankel grade were used to evaluate neurological status.

RESULTSSeven vertebrae with satisfactory postural reduction were treated with PVP, 13 vertebrae with unsatisfactory postural reduction were treated with PKP, 3 patients with spinal cord injury were treated with decompression and posterior short segment fixation at the same time. All patients were followed up from 10 to 48 months with an average of 21.2 months. Cement leakage occurred in 4 cases with no symptom, 1 cases in PVP group and 3 cases in PKP group, there was no significant difference between two groups(=0.561). The priming volume of cement was (6.40±0.94) ml in PVP group and (5.46±1.09) ml in PKP group (>0.05). Three days after operation vs preoperation, the vertebral height restoration and kyphotic improvement was(31.71±11.35)%, (9.79±4.64)° in PVP group and (24.77±8.51)%, (8.15±2.97)° in PKP. There was no significant difference between two groups(>0.05). Three days after operation, VAS of low back pain and ODI in all patients were improved than preoperative data(<0.05), but there was no significant difference between two groups or between postoperative at 3 d and final follow up(>0.05). Nerve function of 3 patients underwent decompression and fixation from Frankel D to E.

CONCLUSIONSAccording to Li staging system and the degree of introperative postural reduction, individualized surgical treatment for Kümmell's disease can obtain good clinical results. Bad postural reduction during operation maybe a risk factor of cement leakage.

OBJECTIVETo compare the effects of close reduction combined with minimally invasive percutaneous plate osteosynthesis for distal fracture of tibial shaft.

METHODSFrom March 2009 to May 2013, there were 124 patients (89 males and 35 females, 30 of them were injured in a traffic accident and 94 were falling down in daily life, the ages ranging from 21 to 81 years old) who suffered from distal fracture of tibial shaft. Sixty-six patients (48 males and 18 females, 45 cases of type A, 12 cases of type B and 9 cases of type C) were treated with close manipulative reduction combined with minimally invasive percutaneous plate fixation. After close reduction, a minimal incision was made and a anatomic plate was inserted just along the medial tibia periostea, and then the fracture was fixed without fracture exposure. The other 58 patients (41 males and 17 females, 41 cases of type A, 10 cases of type B and 7 cases of type C) were treated with conventional open reduction and internal fixation. Length of the incision, operating time, early postoperative pain (recorded using the Visual Analog Scale score) and the outcome results (recorded using the evaluation standard of Johner-Wruhs) were compared.

RESULTSThe length of incision was meanly (7.34 ± 1.42) cm in MIPPO group and (21.82 ± 2.35) cm in ORIF group; operation time was (44.48 ± 10.00) min in MIPPO group and (59.42 ± 11.84) min in ORIF group. The postoperative radiographs verified good position of all screws and satisfactory bone fracture reduction in both groups. All the patients were followed up, and the duration ranged from 10 to 24 months (mean 15.2 months) in both groups. In MIPPO group,only one patient had delayed union and got union after Chinese herb therapy. The other 65 patients got bony union during 15 to 20 weeks. While in ORIF group, 3 patients suffered from nonunion and received reoperation with bone grafting, and 4 patients got bone infection.

CONCLUSIONTreatment of distal fracture of tibial shaft, combined with close reduction and MIPPO technique, has the advantages such as less invasion, less damage of blood supply, simplified procedure of operation and higher union rate, which is an ideal methods and is accordant to the biological demand.
