A turbid solution was formed through the reaction between ?-PGA and cetylpyridinium chloride(CPC) and the turibidity was measured by using ultraviolet-visible spectroscopy at 680nm.The linearity between the concentration of ?-PGA and its absorbance,the stability,repeatability and recovery of the method were studied.Through the reaction of ?-PGA with CPC,a homogeneous turbid solution was formed.The turbid solution was stable in 3h under proper pH value and ion strength,the absorbance of the solution at 680nm had a good linear relationshi Pwith the concentration of ?-PGA in the range 12.5~50?g/ml(R2=0.9939).The recovery was within the range of 86%~99.75%(n=5).The relative standard division of the method for determining ?-PGA at the concentrations of 5,10 and 40?g/ml were 0.14%,0.23%和0.025% repeatability.The turbidmetric method has advantages of convenience,simplicity and good repeatability and can be used to control the quality of ?-PGA and its products.

Cerebral apoplexy is one of the main causes of death in the middle-aged and elderly population,which has higher mortality and disability rate.The incidence of the disease is increasing year by year and it is a serious threat to human life and health.Therefore,it is of great significance to find an effective target for the diagnosis and treatment of stroke.Thioredoxin (Trx) is the major thiol reducing agent in the cells,it is involved in many signal transduction pathways in the cells by regulating the redox state of the cell.It has disulphide reductase activity,which can reduce the oxidative stress injury in the rats after the stroke.Thioredoxin interacting protein (TXNIP) is an endogenous inhibitor of Trx,it can destroy the redox balance and promote the oxidative stress by binding/inhibiting the activity of Trx,while the inhibition or knockdown of TXNIP has obvious neuroprotective effects.Recent studies suggest that Trx/TXNIP may be involved in the pathophysiology of cerebral apoplexy by a variety of pathways.This article analyses the research status of Trx/TXNIP and studies the localization of Trx system in the central nervous system and the progress of Trx system in ischemic cerebral apoplexy.It reviews the mechanism of Trx/TXNIP in cerebral apoplexy and prospectes the signaling pathways involved in the pathophysiological process of Trx/TXNIP to provide new ideas for the treatment of cerebral apoplexy.

Objective To study the protective effect and mechanism of safflower solution on warm ischemia reperfusion injury(IRI) of liver in rats.Methods Male Sprague-Dawley rats were randomly divided as 4 groups: Group S(sham group);group I/R(IRI group);group IPC(ischemic preconditioning group);group SPC(safflower solution preconditioning group).The rats were sacrificed at 24 h after reperfusion,serum levels of ALT and AST were measured and HE staining of liver tissues were made to detect rat liver histological changes and grade liver IRI(Suzuki score);apoptosis were monitored by TUNEL;TNF-?,MIP-2 and ICAM-1 mRNA of liver were measured by RT-PCR;NF-?B gene products of liver were detected by Western blotting.The mean value of all the assay tests was compared.Results After 24 h reperfusion,compared with group I/R,the liver function(ALT and AST) in group SPC and group IPC was significantly improved(P

Objective:To evaluate the effects of endovascular embolization and microsurgical clipping on cognitive function in patients with intracranial aneurysm.Methods:A total of 80 patients with intracranial aneurysms,who were treated in Chongqing Hospital of Traditional Chinese Medicine from March 2014 to September 2015,were selected and randomly divided into control group(n=40) and experimental group (n=40).The control group was treated with microsurgical clipping,and the experimental group,with endovascular embolization.The postoperative cognitive function was assessed by the mini mental state examination scale (MMSE),and length of stay,in-hospital mortality rate,mortality rate in 1 year and the incidence of postoperative adverse reactions were compared between the two groups.Results:The total score (26.78± 0.85) of MMSE in the experimental group was higher than that (22.25± 0.63) of the control group (P＜0.05).The cognitive dysfunction rate (37.50％) of the experimental group was lower than that (55.00％) of the control group (P＜0.05).The length of stay [(6.7± 3.9) days] of the experimental group was lower than that [(9.6± 4.5) days] of the control group(P＜0.05).There were no significant differences in in-hospital mortality rate and mortality rate in 1 year,and the incidence of adverse reactions between the two groups (P＞0.05).Conclusion:Endovascular interventional therapy can improve the cognitive function of the patients with intracranial aneurysms and shorten the length of hospital stay.

Objective To explore a new method for one-stage repair of the intestinal leakage based on the principle of magnetic compression anastomosis. Methods Twenty-four dogs were randomly divided into experimental group (n = 12) and control group (n = 12) according to random number table. The model of upper and multiple intestinal leakages was established by making transverse incisions of 1 cm in length on the jejunum wall about 50 cm and 100 cm away from the Treitz ligament. Forty-eight hours later, two NdFeB magnetic rings with the magnetic flux of 2500 G were put into the intestine from the leak sites. The leak sites were pressed between the two rings. The ventages in the control group were sutured. The condition of the dogs was observed after the repair of the leakage. The excreting time was recorded, and the leakage pressures of the anastomotic stoma were detected.The positions of the magnetic rings in the experimental group were detected by X ray. Tissues of the anastomotic stoma were processed by hematoxylin eosin and Masson staining. All data were analyzed using the two-sample t test. Results Severe abdominal infection occurred 48 hours after the establishment of the model. All the intestinal leakages in the experimental group were successfully repaired and the dogs survived for a long time. The magnetic rings were excreted six or seven days after the repair. Eight dogs of the control group survived. The leakage pressure of the anastomotic stoma seven days after the repair was (134 ±23)mm Hg (1 mm Hg =0. 133 kPa) in the experimental group and (91 ± 18)mm Hg in the control group, respectively, with a significant difference between the two groups (t = 3.225, P ＜ 0.05). The leakage pressure of the anastomotic stoma 14 days after the repair was (281 ±7)mm Hg in the experimental group and (271 ±21) mm Hg in the control group, respectively, with no significant difference between the two groups (t =0. 988, P ＞ 0.05). Histological observation showed that after the magnetic compression anastomosis, the intestinal muscle and mucosa recovered well, inflammatory reaction was slight and less collagen fiber and scar was formed. Conclusions Application of magnetic ring with the magnetic flux of 2500 G in one-stage repair of the intestinal leakage in the state of severe abdominal infection is safe and reliable.

Objective To compare the therapeutic effect,advantages and disadvantages of 2 different methods on female stress urinary incontinence(SUI),vaginal wall suspension via percutaneous puncture(VWS-PP)and tension-free vaginal tape(TVT).Methods Fourteen SUI cases were treated by VWS-PP and 12 SUI cases were treated by TVT.The patients'age and course in 2 treatment groups were similar,and they were followed up 6 weeks,6 months and 1 year post-operatively.Therapeutic effect was evaluated by presence or absence of urinary incontinence when abdominal pressure increased.Meanwhile,operation time and complication were also compared.Results The therapeutic effect in VWS-PP group resembled as in TVT group,but the complication in VWS-PP was much less than that in TVT.The mean operation time of the VWS-PP group was 80 min(range from 60 to 90 min).while that of TVT group was 35 min(range from 25 to 50 min).The difference between 2 groups was statistically significant(P＜0.01).Conclusions The VWS-PP method is an effective,safe and mini-invasive operation for SUI.similar to TVT.Although the operation time in VWS-PP group is much longer than that in TVT group,the trauma is tinier and the surgeon can observe the anatomy reset by ultrasonic wave.

Objective To investigate the correlation of serum concentration of B vitamins B1,B6,B12) with the incidence of epilepsy.Methods We recruited 50 newly diagnosed patients with epilepsy (not receiving antiepileptic drugs) and 50 patients without epilepsy.Serum concentrations of B vitamins (B1,B6,and B12) in both groups were detected with a LK3000V vitamin detector.Results The concentrations of vitamin B1 and B12 in epileptic patients were (132.81 ±7.3l) nmol/L and (221.41 ±26.09) pg/ml,respectively,not significantly different from those in non-epileptic patients [(130.44 ± 5.12) nmol/L,P =0.095 ;(197.87 ± 19.36) pg/ml,P =0.077].The concentration of vitamin B6 in epileptic children was (44.61 ±2.49) μmol/L,significantly lower than that in non-epileptic children [(64.63 ± 5.71) μmol/L,P =0.031].Conclusion Though serum concentrations of vitamin B1 and B12 may not be associated with epilepsy,lower concentration of vitamin B6 in serum may increase the risk of epilepsy.

To explore the expression of Beclin1 in osteosarcoma and investigate the effects of down-regulation of autophagy on the chemotherapeutic sensitivity to cisplatin (DDP), the expression of Beclin1 in 28 specimens of osteosarcoma (group A) and 19 specimens of normal bone tissues (group B) were immunohistochemically detected. The expression of Beclin1 mRNA in MG63 cells treated with different concentrations of DDP was examined with RT-PCR. After down-regulation of autophagy in MG63 cells by an autophagy inhibitor, 3-methyladenine (3-MA), the cell proliferation inhibition rate of MG63 cells treated with DDP was evaluated by using the MTT assay. The positive rates of Beclin1 were 67.85% in group A and 94.73% in group B. Its expression was lower in osteosarcoma than in normal bone tissues, with a significant difference found between them (P<0.05). RT-PCR showed that the expression of Beclin1 mRNA in the cells treated with high-dose DDP were higher than that in the non-treated cells, and no significant difference in the expression of Beclin1 mRNA was found between the cells treated with low-dose DDP and the non-treated cells. There was a positive correlation between the level of Beclin1 mRNA expression and the concentration of DDP. MTT assay showed that the proliferation inhibition rates of the cell treated with 3-MA and DDP combined were substantially increased when compared with those treated with DDP alone (P<0.01). This study demonstrated that autophagy may be implicated in the carcinogenesis of osteosarcoma, and DDP may induce autophagy in the MG63 cells. It also suggests that the down-regulated autophagy could increase chemotherapeutic sensitivity of DDP to osteosarcoma.

Objective To investigate the prevalence and clinical features of fulminant type 1 diabetes.Methods Using data retrieved from Second Xiangya Hospital of Central South University,all patients diagnosed with type 1 diabetes from Jan.1,2001 to Dec.31,2007 were identified.The patients were divided into fulminant type 1 diabetes (F1D) group,typical type 1 diabetes (T1A) group,and idiopathic type 1 diabetes(T1B) group.Their clinical features were compared.Results Eight patients (9.1%) fulfilled the criteria for fulminant type 1 diabetes among 87 newly diagnosed type 1 diabetes,and the percentage of fulminant type 1 diabetes reached 14.0% among type 1 diabetic patients with age of onset of 18 years or older.Patients of F1D group had a markedly higher plasma glucose concentration compared with patients of T1A group and T1B group(P=0.004).Serum amylase was higher in F1D group than that in T1A group(P = 0.021).Four (50%) patients were GADA positive,among whom 1 patient was Coxsackie B virus (CVB) IgM positive and 1 patient was Herpes Simplex virus 1 (HSV1) IgM positive.Conclusions Fulminant type 1 diabetes accounts for about 10% of the type 1 diabetes in the Chinese individuals with ketosis-or ketoacidosis-onset.Patients with this subset of diabetes had severe metabolic derangement.Viral infection and autoimmunity may be involved in the pathogenesis of fulminant type 1 diabetes.
