Rosiglitazone was used for intervention of atherosclerosis in diabetic rabbits.The results showed that the intima/medium thickness ratio,cross section area of plaque,and the expressions of NADPH oxidase p22phox,gp91 phox were decreased;while the total anti-oxidative ability was increased after administration of rosiglitazone as compared with the non-intervention group(all P<0.05).Compared with rosiglitazone treatment group,serum hepatocuprein leveI in rosiglitazone prevention group was increased,while serum malonaldehyde level decreased(both P<0.05).This study suggests that rosiglitazone may have the effect of reducing the oxidative stress and the formation of atherosclerotic plaque in diabetics.

Objective To explore the clinical characteristics,changes of neuroendocrine hormone before and aftter operation in patients with craniopharyngioma,so as to provide the basis for the replacement therapy after operation and educational practice.Methods The clinical data of 183 patients with craniopharyngioma were retrospectively analyzed. Results (1)Symptoms mainly were headache with nausea,disevesight,the second symptom was polydipsia and polyuria,in child,growth and development retardation was more,and another was hypothalamus syndrome.(2)Functions in endocrine:functions in thyreoid,adrenal and gonad(except PRL),the dysfunctions in neurohypophysis was displayed with completed insipidus and immaturity insipidus,contrasted it anteoperation to that postoperation,it was obvious in statishcs meanings (P＜0.05). Conclusions In patients with craniopharyngioma,children and adolescent is more than the other people,clinical situation is complicated,neuroendocrine hormone is derangement before and after operation,tumor itself to oppress and operation trauma are the basic reasons for the hypofunction of neuroendocrine hormpne,hormones replacement therapy and monitoring should be catch earlier.

Objective To investigate the effects of fluvastatin on expression of connective tissue growth factor (CTGF)in the myocardium of diabetic rats. Methods Thirty-two Sprague-Dawley rats were randomized into four groups: normal control, untreated and STZ-induced diabetic rats, and diabetic rats treated with low-dose and high-dose fluvastatin.After 12 weeks′ intervention, body weight as well as the weights of both whole heart and its left ventricle were measured to calculate the ratio of heart weight to body weight (H/B) and the left ventricle mass index (LVMI).The mRNA expression of CTGF, transforming growth factor β1 (TGF-β1), fibronectin (FN),collagen type Ⅲ (ColⅢ) in the myocardium were detected by RT-PCR. Results Compared with the normal control group, the untreated diabetic group showed the increased (all P<0.05) H/B, LVMI and mRNA expressions of CTGF, TGF-β1, FN, and Col Ⅲ in the myocardium. In addition to the effective regulation of lipid metabolism, fluvastatin treatment could obviously reduce the increment of H/B and LVMI(P<0.05～0.01), and suppress the mRNA expressions of CTGF, TGF-β1, FN, and Col Ⅲ in the myocardium of diabetic rats(P<0.01).The down-regulation of CTGF was more significant than that of TGF-β1.All these effects were in dose dependent way. Conclusions Fluvastatin inhibits extracellular matrix accumulation in the myocardium of diabetic rat.Down-regulating the overexpression of CTGF in diabetics is an underlying mechanism of fluvastatin in the cardiac protection.

From May 2012 to May 2013, 60 chronic male smokers received an intravenous infusion of dexmedetomidine 1 μg/kg (Group D, n=30) or an equal volume of normal saline (Group C, n=30) before anesthesia induction.At time of dexmedetomidine or normal saline dosing , after induction of anesthesia, 1 and 3 min after intubation, the heart rates and rate-pressure products were significantly lower in Group D than Group C ( P<0.05 ).Thus the dosing of dexmedetomidine before anesthesia induction could suppress the cardiovascular responses of endotracheal intubation in chronic smokers and avoid increasing myocardial oxygen consumption so as to protect heart functions.

R. China. The roles of criteria to guide and accelerate the transition from schistosomiasis control to elimination are concluded ,based on this system?atic review how the criteria led the implementation of the medium?and long?term national plan and provided the guidance when drafting the thirteen?five years national plan for schistosomiasis,and the suggestion to draft more criteria related to schistosomia?sis elimination program and strengthening the implementation of current criteria,so as to precisely guide the schistosomiasis elimination program in P. R. China.

Objective:To explore the clinical characteristics of patients with pituitary thyrotropin-secreting adenoma and evaluate the effect of preoperative short-acting octreotide treatment on hyperthyroidism.Methods:A retrospective analysis was performed in 40 patients with pituitary thyrotropin adenoma diagnosed in Beijing Tiantan Hospital from January 2008 to January 2018. The general data, laboratory examinations and imaging findings were reviewed and analyzed. The clinical effect of preoperative octreotide on hyperthyroidism was evaluated.Results:The age of onset year of the 40 patients (male: female = 24∶16) was (30.5±5.1) years. Among them, 35 patients (87.5%) were with macroadenoma. The most common symptoms were thyroid hypermetabolism syndrome, followed by headache, dizziness, visual field damage and hypogonadism. The thyroid function of 30 patients (75%) recovered to normal within 3-5 days after the octreotide treatment. The total effective rate of the octreotide was 90.0%. The level of free thyroxine (FT 4) before treatment in patients with more than 10 times of effective cumulative dose was significantly higher than that in patients with less than 10 doses. Conclusions:Thyroid hypermetabolism syndrome and pituitary occupying effect are the most common clinical manifestations of thyrotropin-secreting adenoma. Preoperative octreotide treatment can effectively control hyperthyroidism. The level of FT 4 is a crucial factor affecting the efficacy of octreotide.

Objective To discuss the surgical strategy of parasagittal and falcial meningiomas in the middle 1/3 cortex area and raise resective rates of tumors and surgical effects.Methods The clinical,imaging and operative data of 74 cases of parasagittal and falcial meningiomas in the middle cortex area which underwent operation were reviewed and followed up.Results Of 74 tunors,67 were resected with Simpson Ⅱ grade,7 with Simpson Ⅲ,none of them with Simpson Ⅰ.Superior sagittal sinus and the vein of central suleus and feeders of cortex were reserved well.Severe brain injury was not occurred in 66 cases with tumors debulking(Simpson Ⅱ 61 cases,Simpson Ⅲ 5 cases),the neuro-functions of patients were normal or transient slight weakness of contralateral lower extremities postoperatively.Tumors of 8 cases were "turned over" and resected by piecemeal (Simpson Ⅱ 6 cases,Simpson Ⅲ 2 cases),weakness and paralysis of contralateral lower extremities occurred in 7 cases and 1 cases respectively after surgery.Followed-up ranged from 6 months to 4 years and 2 months,4 cases were lost to follow-up.Neuro-function of all cases with weakness of contralateral lower extremities recovered after one month.Muscle strength of the cases with paralysis of contralateral extremity recovered to grade Ⅳ 6 months later,no recurrence and death.Conclusion The measures,including piecemeal tumor reseeted mierosugically,good protection of the vein of central sulcus,excellent management of superior sagittal sinus,and avoiding damage to functional cerebral cortex during operations,are best ways for raising the tumor resection rate and nearo-function reserved.

Objective To study the possibility of using heterogeneous antiserum in single radial immunodiffusion (SRID) for quantitative detection of HA in H7N9 influenza vaccine product when H7N9-specific antiserum is not available in order to establish a testing method for the detection of H 7N9 antigen in any urgent situation.Methods Antisera specific for H7N1, H7N2, H7N3 and H7N7 were obtained from NIBSC and used for SRID assay .Amino acid sequences of hemagglutinins were comparatively analyzed be-tween H7N9 virus and other viruses used to prepare heterogeneous antiserum .The titers of antisera against H7N9 and their homogenous antigens were detected by double immunodiffusion method .Based on the results of homology analysis and cross-reaction, a suitable antiserum was selected and its applicability was further validated by the SRID assay using H7N9 antigen.Results Influenza A virus subtype H7N3 that used for preparation of 07/278 antiserum showed the highest HA homology with H7N9 (97.14%).The titer of 07/278 antiserum against H7N9 antigen was 1 ∶8 as detected by double immunodiffusion assay .The H7N9 anti-gen and the 07/278 antiserum could form a clear precipitation line in SRID assay .The detection of H7N9 antigen in the range of 10 to 40μg/ml showed a good linearity in the standard curve .Conclusion The 07/278 antiserum from NIBSC can be used as an alternative reagent for the quantitative detection of hemaggluti -nin in H7N9 influenza virus vaccine .

Objective To investigate the effect of nitric oxide synthase(NOS) inhibitors and L-arginine(L-Arg) on the prognosis of traumatic shock in rats. Methods Traumatic shock models of Sprague-Daulay rats were made and randomly devided into control group (n=24),L-NAME treatment group (n=24),AG treatment group (n=24) and L-Arg treatment group (n=24). Serum nitric oxide(NO) levels and oxygen partial pressure in tissues include skeletal muscles,liver and small intestine were detected at 1h,3h,5h after resuscitation. Meanwhile, hemodynamic data of the rats and their survival rates of 12h and 24h were monitored and recorded. Results Serum NO concentration was statistically lower after resuscitation in L-NAME group than that in control group, while there were no statistical significance of tissues oxygen partial pressure and survival rate in 12、24h between the two groups. AG could decrease serum NO levels only at late stage of traumatic shock,but no effect on the synthesis and relase of NO at early stage of traumati shock.AG could improve tissues oxygen partial pressure of the liver and small intestine, and prolonged the mean survival time. L-Arg could increase serum NO levels, and improve oxygen partial pressure of intestine and significantly increase the survival rate at 12h and 24h in rats with traumatic shock. Conclusions Treatment with AG and L-Arg can improve the prognosis of traumatic shock rats much better than that with L-NAME.
