Excessive release of glutamic acid plays an important role in the occurring and development of many nervous system diseases.Ionotropic glutamate receptors antagonists are shown to have therapeutic effect in animal models,but their clinical application is limited by their effects of blocking the normal excitatory neurotransmission.However,metabotropic glutamate receptors can suppress the release of glutamic via presynaptic mechanisms,which makes them the new targeting points of certain nervous system disease.This paper reviews the recent research progress of mGluRs in nervous diseases both at home and abroad.

Objective Analysis of early risk predict markers within 24h after admission of prognosis in severe acute pancreatitis (SAP). Methods Medical records of 127 patients with sever acute pancreatitis admitted to our hospital within 72h after onset from February 2006 to July 2009 were retrospectively analyzed. These inpatients were grouped into survival group (102 cases) and death group (25 cases). The clinical and laboratory data within 24h after admission were compared between two groups. Results Compared with survival group, patients in death group had significantly difference in heart rate, respiratory, PaO2, pH value, serum calcium, serum kalium, serum creatine, BUN, BE, LDH, serum albumin and APCHE Ⅱscores (P<0.05). Higher APCHE Ⅱ scores after admission was an independent early high risk predicator of death. Conclusions Death group was characterized as severe multiple organ dysfunction and severe internal disturbance. Heart rate, respiratory, PaO2, pH value, serum calcium, serum potassium, serum creatine, BUN, BE, LDH, serum albumin and APCHE Ⅱ scores were early risk predict markers of death in patients with sever acute pancreatitis.

AIM: To study the dermal toxicity and absorption of Triptolide Compound Cream.METHODS: 2% azone+1% volatile oil of twig from Camellia.oleifera was used as permeation enhancer to prepare Triptolide Compound Cream.Acute dermal toxicity,irritation a sensitization test on mouse were carried out.And mouse skin in vitro was applied for studying the administration. RESULTS: This compound cream had no acute toxicity,irritation or hypersensitive effects.2% azone+1% volatile oil had more powerful enhancement effects.after 12 h,amont of drug delivery/unit area Q/(?g/cm2) and absorption percentage Q% of triptolide and meloxican in the preparation reached a platea conventration.The results also showed that there was a good linear correlation between the accumulative permeated amount per unit area and the time. CONCLUSION: The study showed that Triptolide Compound Cream has no toxicity on skin,and there is a good dermal absorption.

Objective To explore the lower limbs joints movement of patients with unilateral and primary artificial hip replacement in convalescence. Methods 100 cases of patients with unilateral and primary artificial hip replacement in convalescence were chosen as the ob-servation group,while 100 cases of matched healthy subjects were included as the control groups. The three-dimensional kinematics and mo-tion of lower extremities were monitored. Results The difference in operated knee flexion,operated ankle planter flexion and operated hip flexion of the observation group and the observation group were statistically significant(P<0. 05). The difference in the joint angle peak of hip backward extension of sagittal section,hip adduction of frontal plane,knee adduction of frontal plane,ankle adduction and outreach of frontal plane,hip internal rotation and extorsion of horizontal plane,ankle rotation and extorsion of horizontal plane in two groups were statisti-cally significant(P<0. 05). Conclusion There are abnormal prosthetic joint movement,limited range of operated movement in patients with unilateral and primary artificial hip replacement in convalescence,and coterminous kinematic chains appear compensatory changes,it should strengthen the muscle exercises of operated hip.

Paroxysmal nocturnal haemoglobinuria ( PNH) is a clonal hematopoietic stem cell disease characterized by intravascular hemolytic anemia , pancytopenia and thrombosis .Although PNH is an non-malignant disease , its complications have very negative impacts on patient's quality of life .The most common serious complication is thrombosis formation .

ObjectiveTo investigate the clinical value and pathological basis of peritumoral hyperenhanced rim (PHR) of renal cell carcinomas (RCCs) on CEUS.MethodsCEUS images of 53 patients with 54 renal tumors (27 RCCs,27 renal angiomyolipomas) were analyzed,and the detection and distribution of PHR were evaluated.HE staining and immunohistochemistry of CD34 were performed in tissue surrounding RCCs (TSR) to observe distribution of psuedocapsule,large vessels,and microvasculars among TSR with different modes of PHR.ResultsPHR was found only in RCCs.PHR distribution between RCCs and angiomyolipomas was statistically different (P＜0.05).Using PHR to diagnose RCC,the sensitivity,specificity,positive predictive value,negative predictive value,false positive and false negative was 44.44％ (12/27),100％ (27/27),100％ (12/12),64.29％ (27/42),0 (0/27) and 35.71％ (15/42),respectively.Pseudocapsule distribution between RCCs with PHR and RCCs without PHR was not statistically different (P＞ 0.05).There were rich large blood vessels in TSR with PHR in washin and both phases,and few or thimbleful large vessels were found in TSR without PHR in washout phase.Cancer tissue near the boundary (CTNB) of TSR had the highest microvessel density (MVD).MVD differences in different TSR with PHR were statistically different between washin and washout phases,washin and both phases,both phases with PHR and without PHR (P＜0.05),but no statistical difference was found between washout and both phases (P＞0.05).ConclusionPHR is a highly specific complementary indicator in diagnosing RCC,and it is correlated with rich blood vessels in TSR and (or) a higher MVD value in CTNB.

Objective To compare the efficacy and safety of vitrectomy combined with internal limiting membrane flap and vitrectomy combined with internal limiting membrane peeling for the treatment of idiopathic macular hole with different sizes.Methods A total of 127 consective patients (127 eyes)were divided into two groups according to the size of the hole diameter of the smallest split points by less than or equal to 500 μm (small diameter macular hole group) and more than 500 μm (huge diameter macular hole group).According to different surgical methods the patients were divided into non ILM flap coverage group (peeling 1 group and peeling 2 group) and ILM flap cover group (covering 1 group and covering 2 group).All the patients underwent vitrectomy combined with internal limiting membrane peeling or vitrectomy combined with limiting membrane flap.Preoperative and postoperative best correct visual acuity,closure ratio of macular hole and postoperative major complications were observed and followed up.Results The postoperative best correct visual acuity improved in all the groups,there was no significance difference between small diameter macular hole group and huge diameter macuiar hole group (t =0.112 2,0.750 8;all P ＞0.05).The closure ratio of peeling 1 group and covering 2 group at postoperative 6 months were all 100％,there was no statistical difference (P ＞ 0.05),which in peeling 2 group and covering 2 group were 84.85％ and 100.00％,there was statistical difference (x2 =13.292,P ＜ 0.05).There was no statistical difference in preoperative defect diameter of the inner and outer junction between peeling 2 group and covering 2 groups (P ＞0.05),there was also no statistical difference between peeling 2 group and covering 2 groups at postoperative 1 months (P ＞ 0.05),but there were statistical differences at postoperative 3 months,6 months and 12 months (all P ＜ 0.05),the covering 2 group were less than the peeling 2 group.Conclusion ILM flap coverage helps to heal macular holes greater than 500 μm diameter,and has no extra effect on healing of diameter less than 500 μm.
