ABSTRACT
Patients with spinal cord injury is associated with seriously affected gastrointestinal function and imbalance of intestinal flora, leading to increased inflammation of spinal cord nerves. With the proposal of the theory of gut microbiota-gut-brain axis in recent years, the regulatory role of gut microbiota in the central nervous system and gastrointestinal system has gradually attracted attention. Although a considerable number of studies have focused on the effects of intestinal flora characteristics on spinal cord nerve function repair in patients with spinal cord injury from different perspectives, there are numerous research models for treating spinal cord injury with intestinal flora as intervention targets and remains a lack of unified and effective clinical treatment methods. In this paper, the authors review the research progress in characteristics of intestinal microflora and intestinal microflora-targeted therapeutic methods in patients with spinal cord injury, hoping to provide a reference for the clinical treatment and basic research of spinal cord injury.
ABSTRACT
Acupuncture can improve the motor and non-motor symptoms of Parkinson's disease, and the effect of acupuncture combined with drug therapy is better than that of drug therapy alone. The possible mechanism includes inhibiting α-synuclein aggregation, oxidative stress, and neuroinflammation, inhibiting the apoptosis of dopaminergic neurons, and achieving a neuroprotective effect. The points mainly selected for Acupuncture treatment for this disease are Zusanli (ST 36), Yanglingquan (GB 34), Taichong (LR 3), Xuehai (SP 10), and other points. Early use of acupuncture and acupuncture combined with medical treatment strategy is worthy of clinical application.

Objective To explore the role of nuclear translational factor homeobox A13(HOXA13)gene in epithelial - to - mesenchymal transition(EMT)induced by human serum albumin(HSA)overload in human renal tu-bular epithelial(HKC)cells. Methods HKC cells were treated with different concentrations of HSA(ranging from 0 - 30 g/ L)for 48 h or 20 g/ L HSA for different times(ranging from 0 - 72 h)in vitro. The protein expressions of cy-tokeratin(CK),Vimentin,and HOXA13 protein in HKC cells were detected by using Western blot respectively. Mean-while,liposome - mediated DNA transfection was used to transfect the HOXA13 gene into HKC cells before HSA treat-ment,and the expressions of CK,Vimentin and HOXA13 protein in HKC cells were also detected by using Western blot. Results (1)The protein expression of CK decreased but Vimentin increased after HKC cells were exposed to HSA,which was in a concentration - and time - dependent manner.(2)Expression of HOXA13 was down - regulated by HSA in a dose - and time - dependent manner,and the expressions of HOXA13 protein in HKC in 5 g/ L,10 g/ L, 20 g/ L,30 g/ L group were 58. 24%(P = 0. 005),44. 73%(P = 0. 003),38. 40%(P = 0. 033)and 24. 83%(P =0. 011)respectively as compared with 0 g/ L group. Likewise,the protein expressions of HOXA13 in 24 h,48 h,72 h group were 52. 00%(P = 0. 023),46. 83%(P = 0. 008)and 35. 10%(P = 0. 034)respectively as compared with 0 h group.(3)There was a positive correlation between the levels of HOXA13 protein expression and CK protein expression (r = 0. 86,P = 0. 005),while the relationship between the levels of HOXA13 protein expression and Vimentin protein expression was negative(r = - 0. 94,P = 0. 002).(4)Up - regulated expression of HOXA13 in HKC cells by lipo-fectamine transfection alleviated the degree of EMT induced by HSA significantly. The expression of Vimentin decreased by 35. 34%(P = 0. 005)while the expression of CK increased 360. 00% - fold(P = 0. 005),compared with that of untransfected HKC cells. Conclusion EMT induced by HSA in HKC cells may play a role through HOXA13.
ABSTRACT
BACKGROUND:Demineralized bone matrix as bone tissue engineering biological scaffold material is more researched currently, which has osteoinductive and osteoconductive. OBTECTIVE:To summarize the development of demineralized bone matrix as bone tissue engineering scaffold material and to prospect its trend. METHODS:The relative literatures addressing demineralized bone matrix as bone tissue engineering scaffold material published between January 1965 and May 2013 in PubMed database, Chinese Biomedical Database, Wanfang Database and FMJS database were searched by the first author. The key words were“demineralized bone matrix, scaffold material, growth factor, cells, drugs”in English and Chinese. According to the inclusion criteria, repetitive researches were excluded, and final y 34 articles were included. RESULTS AND CONCLUSION:Scaffold material is the key composition of tissue engineered bone, and only demineralized bone matrix has both osteoinductive and osteoconductive properties which cannot only provide space for bone repair, but also can be combined with bioactive factors, living cells, antibiotics in vitro to construct bone graft thereby promoting healing of bone defects. However, this technique is also facing some problems to be solved such as the ratio of demineralized bone matrix and various substances, disinfection, preservation of osteogenetic activity and antigenicity elimination. Sufficiently understanding demineralized bone matrix as bone tissue engineering scaffold can provide a theoretical basis for its clinical service.
ABSTRACT
This study is to report the establishment of an UPLC-MS/MS method for the determination of plasma concentration of UA carried in self-microemulsifying drug delivery system (SMEDDS) and its pharmacokinetics in rats. It was used for determination and analysis when serum with internal standard was extracted from C18 solid-phase column. Acquity UPLC BEH C18 column (100 mm x 2.1 mm, 1.7 microm) was used for separation. The mobile phase was acetonitrile -0.1% ammonia with gradient elution at the flow rate of 0.2 mL x min(-1). The column temperature was 40 degrees C and the detection wave length was 210 nm. It was detected by negative ion using electrospray ionization source (ESI) and scanned by multiple reaction ion monitoring (MRM) mode. The liner relationship of UA was very good in the range of 1.19-3 815.00 ng x mL(-1) (r = 0.999 0). Recovery rate of different concentrations were 87.42%-89.95%. The precision of inter-day and intra-day were less than 11%. The method developed in our study was proved to be sensitive, rapid and simple. It is suitable for the pharmacokinetic study of UA-SMEDDS in rats.
ABSTRACT
Objective:The present study aimed to investigate the short-term efficacy and adverse effects of induction chrono-che-motherapy including docetaxe1 (TXT), cisplatin (DDP), and 5 fluorouraci1 (5-FU) followed by concomitant chemoradiotherapy in lo-co-regionally advanced nasopharyngeal carcinoma (NPC). Methods:Newly diagnosed locally advanced (Ⅲ~Ⅳb) NPC patients were enrolled in this study. All patients received three cycles of TPF regimen. The TPF chemotherapy regimen was administered as follows:TXT, 75 mg/m2, i.v. infusion, d1; DDP, 75 mg/m2, bolus infusion from 10:00 to 22:00, d1-5; and 5-FU 750 mg/m2/d bolus infusion from 22:00 to 10:00, d1-5, with 21 days each cycle, followed by concomitant IMRT and chemotherapy (paclitaxel 135 mg/m2 i.v. infu-sion, with 21 days each cycle and a total of 2 courses). Acute and late toxicities were graded according to the Common Terminology Cri-teria for Adverse Events v3.0 scoring criteria. Tumor response was evaluated using 2000 Response Evaluation Criteria in Solid Tumors criteria. Results:The CR and PR rates of induction chemotherapy were 23.8%and 68.6%, respectively;whereas the CR and PR rates of the combined modality treatment were 64.8%and 31.4%, respectively. Two-year overall survival rate was 91.4%, two-year progres-sion free survival rate was 87.0%, and two-year distant metastasis-free survival rate was 88.4%. The main side effects from induction chemotherapy include an over grade 3 granulocytopenia of 28.6%. Major toxicity from concurrent chemo-radiotherapy was oral mucosi-tis (81.0%);grade 3 to 4 oral mucositis was 16%. No treatment-related deaths occurred in this study. Conclusion:Induction chrono-che-motherapy using TPF followed by concurrent chemoradiotherapy of paclitaxel is a well-tolerated treatment with short-term efficacy and severity for locally advanced NPC. Further follow-up is required to assess the late effects and long-term efficacy.
ABSTRACT
ObjectiveTo investigate the delineation of gross tumor volume (GTV) in locally advanced nasopharyngeal carcinoma (LANC) according to imageological changes before and after induction chemotherapy (IC) in order to decrease high dose area and protect normal tissue better.MethodsBetween Mar 2010 to Jan 2011,11 patients with LANC were enrolled and treated with TPF regimen followed by intensity-modulated radiotherapy (IMRT) with concurrent chemotherapy,target volumes were delineated based on fused CT imaging before and after IC following project determination.Tumor target volumes after and before IC were respectively delineated according to imaging tumor residues and were overlaid by CTVnx in order to ensure radical doses for the imaging tumor volume before IC,the resulting differences of tumor target volumes of IC before and after were measured and analyzed by paired t-test.ResultsBefore and after IC,the average volumes of GTVnx were respectively 44.72 cm3 and 28.87 ( t =3.89,P =0.003 ),the average volumes of GTVnd were respectively 32.76 cm3 and 19.82 cm3 ( t =2.47,P =0.033 ),the volumes of maximum dose area in brainstem and spinal cord as well as eyeball decreased ( t =2.93-4.59,all P ＜0.05).ConclusionsLANC treated by 3 cycle TPF regimen followed by IMRT with concurrent chemotherapy showes significant shrinkage of tumor volume.The volume of high dose region which caused by normally recovered tissues were decreased by re-delineation of target volume in brainstem and spinal cord as well as eyeball of CT images after IC.
