Acetazolamide, a sulfonamide-derived medication, is frequently used in the treatment of various types of glaucoma. But this kind of medicine is associated with acute angle closure glaucoma. This paper is a review for the researches of this rare adverse reaction at internal and abroad. It can prompt more ophthalmologists to understand and pay attention to this rare adverse reaction of acetazolamide and sulfonamides derived drugs. Then the doctor will make accurate diagnosis, timely treatment and grasp the right operation opportunity and reduce the occurrence of postoperative complications ultimately.

Aim To investigate the relationship between neuronal nicotinic acetylcholine receptor and the amnesia and hypnosis induced by enflurane in mice.Methods Animal models were established by Intraperitoneal injecting of enflurane(2.2 ml?kg-1 and 0.4 ml?kg-1).Artificial cerebrospinal fluid or different dose of nicotine were intracerebroventricular injected,then sleeping time in the analeptic test was recorded;and the step down latency and error times in the step down test;step through latency and error times in the step through test.For the independent activity test,recorded the independent activity times of mice treated with enflurane(0.4 ml?kg-1) in 5 min.Results Compared with control group,intracerebroventricular nicotine decreased sleeping time in the analeptic test,increased step down latency and step through latency in both step down test and step through test.Furthermore,the error times were decreased in both tests.All the outcomes were significant and the influence was dose-dependent.There was no significant difference for the independent activity times of mice treated with 0.4 ml?kg-1 enflurane by ip injection.Conclusion All the evidence suggested that neuronal nicotinic receptor is one of important targets for the hypnotic and amnestic effect of enflurane in mice.

OBJECTIVE:To compare the effectiveness and safety of low-molecular-weight-heparin(LMWH)calcium and rivar-oxaban in preventing lower extremity deep venous thrombosis (DVT) in the elderly patients after surgery of replacement of frac-ture. METHODS:A total of 58 elderly patients underwent hip or artificial femoral head replacement were randomly divided into LMWH group (29 cases) and Rivaroxaban group (29 cases). All patients received basic prevention and physical prevention for DVT after surgery. Based on this,LMWH group was given Heparin calcium injection 4100 IU subcutaneously 10 h after surgery, for 10 d. Rivaroxabar group was given Rivaroxaban tablet 10 mg 10 h after surgery,once a day,for consecutive 10 d. The occur-rence of DVT and positive D-dimer were observed in 2 groups after surgery. The PT,APTT,TT,FIB and platelet counts abnormal-ity were also observed in 2 groups. RESULTS:There was no statistical significance in the incidence of DVT,the occarrence of pos-itive D-dimer,PT,APTT,TT,FIB and platelet counts abnormality 4,10 d after surgery between 2 groups(P>0.05). CONCLU-SIONS:LMWH and rivaroxaban both can be used for lower extremity DVT in the elderly patients after replacement of fracture sur-gery of and have similar therapeutic efficacy and safety.

[Summary] SIRT3 is a member of the silent information regulator 2 ( Sir2) family, located in the inner mitochondrial membrane, with a strong effect of deacetylation. SIRT3 not only modulates energy metabolism, cell apoptosis, tumor growth, anti-aging etc. , but also plays an important role in the field of cardiovascular diseases. In this review, we summarize recent findings related to SIRT3 with metabolic syndrome and cardiac hypertrophy, to provide a theoretical basis for the further study on the potential role of SIRT3 in cardiovascular diseases.

Sirt3 is a kind of nicotinamide adenine dinucleotide (NAD+)-dependent deacetylases.Sirt3 is localized in mitochondria and has been involved in a wide range of mitochondrial biological functions, such as nutrient oxidation、ATP generation, reactive oxygen species (ROS) detoxification and mitochondrial homeostasis.Sirt3 plays an important role in the occurrence and development of cardiovascular diseases.Increased expression of Sirt3 gene has been associated with extended lifespan of humans.

Objective The study was aimed to detect the correlation of B cell activating factor (BAFF) promotor polymorphism-871 C/T and systemic lupus erythematosus (SLE).Methods BAFF promotor polymorphism-871 C/T was detected by the means of allele specific polymerase chain reaction (ASPCR) and agarose gel electrophoresis in 76 cases of SLE and 80 nonthrombosis normal individuals.The data of genotypic frequency and allele genotypic frequency were analyzed statistically with x2 test between the two groups.Results Fifty-one point two percent of normal individuals exhibited C/C.Thirty-five percent were heterozygous for C/T,and 13.8％ were homozygous for T/T.SLE group exhibited a different distribution pattern (30.3％ C/C,43.4％C/T,26.3％T/T).The allele frequency of T in SLE and normal individuals was 48.0％ and 31.2％ respectively.There was significant difference in the BAFF-871 C/T genotypic frequency between the SLE and nonthrombosis normal individuals (P＜0.05).Conclusion The polymorphism-871 C/T of BAFF promoter is correlated with the pathogenesis of SLE.The gene may be a major susceptible gene for SLE in Chinses Han people.Further investigations may be needed.

Objective To investigate the impact of overweight and obesity on left atrial (LA) function in healthy subjects with excess body weight.Methods Conventional echocardiography and tissue Doppler imaging were performed in 30 obese subjects (BMI≥28 kg/m2),30 overweight subjects (BMI,24to 28 kg/m2) and 30 age-matched normal subjects (BMI＜24kg/m2).Strain (S),peak systolic strain rate (SSR),peak early diastolic strain rate (ESR) and peak late diastolic strain rate (ASR) values were used to evaluating LA function.Results Compared with controls,mean S,SSR and ESR were decreased in obese subjects,while mean SSR,ESR and ASR were decreased in overweight subjects.Compared with overweight subjects,mean ESR was decreased in obese subjects.Conclusions An impaired LA function is found in overweight and obese subjects who has no other clinically appreciable cause of heart disease by using strain and SR imaging.

Objective To further elucidate the clinical manifestations and pathological characteristics of lipoprotein glomerulopathy (LPG) . Methods Data of 7 LPG patients were reviewed retrospectively. Clinical manifestations were recorded on the day of renal biopsy. Biochemical profiles of lipid and lipoproteins were examined. Plasma concentration of apoE was determined with radial immunodiffusion assay. Biopsy specimens were processed for light microscopy, immunohistochemistry staining and electron microscopy. Glomerular deposition of apoA, apoB and apoE were detected using monoclonal antibodies on cryostatic sections in all patients. Results All the seven patients presented with edema, microscopic hematuria, heavy proteinuria, anemia and enlarged kidney size. Most of them, the levels of serum creatinine were normal. Biochemical profile revealed that the levels of triglyceride, apoB and apoE were elevated markedly. In all cases, increments of glomerular size and lipoprotein thrombi that occupied capillary lumica in the glomeruli were observed. Immunohistochemistry staining showed that the thrombi were strongly positive for apoA, apoB and apoE. Granules and various size of vacuoles in the thrombi were observed under electronic microscopy. Conclusion Compared with the previous reports of LPG from other countries, some unique clinical and pathological features are found in this group of Chinese LPG patients.

Objective To assess left ventricular synchronicity in patients with metabolic syndrome(MS)by tissue Doppler imaging.Methods Twenty-two patients with MS and left ventricular hypertrophy(LVH)(MS-LVH group),69 patients with MS and non-LVH(MS-NLVH group)and 33 healthy subjects(control group) were included.Left ventricular(LV)systolic and diastolic synchronicity were determined by measuring the maximal difference in time to peak myocardial systolic contraction(Ts-diff)and time to peak myocardial early diastolic relaxation(Te-diff),and the standard deviation of time to peak myocardial systolic contraction(Ts-SD)and early diastolic relaxation(Te-SD)with 6 basal and 6 middle LV segments.Results Compared with control group,patients with MS in MS-NLVH and MS-LVH group showed significantly prolonged Ts-diff,Ts-SD,Te-diff and Te-SD.Furthermore,Te-diff and Te-SD were much more prolonged in MS-LVH group than in MS-NLVH group.Conclusions Patients with MS have impaired L V systolic and diastolic synchronicity.LVH impacts the LV diastolic synchronicity much more obviously than systolic synchronicity in the patients with MS and LVH.
