The trial group was administered Hexue mingmu tablets, control group was treated by hemocoagulase.
●RESULTS: The absorbing time of trial group was shorter than that of the control group. And there was statistical significance between the two groups (P<0. 05).
● CONCLUSlON: Hexue mingmu tablets is an effective medicine to treat traumatic hyphema. Ultrasound biomicroscopy can be used as a routine examination method in traumatic hyphema.

The type of basic media and the contents of plant growth substances were investigated by orthogonal design experiment,and also the effects of different culture conditions on the growth of suspension cells and the accumulation of total flavonoids in Eucommia ulmoides were studied.The results showed that B5 medium supplemented with 0.5mg/L NAA,0.6mg/L 6-BA and 30g/L sucrose,at initial pH 5.0～5.5,20g(FW)/L inoculation quantity and 110 r/min of rotation speed was a preferable culture conditions for E.ulmoides suspension cells growth and flavonoids synthesis.The results of metabolic kinetics analysis for E.ulmoides cell suspension culture showed that the logistic and Luedeking-Piret equations can be used for describing the kinetics of cell growth,sucrose consumption and flavonoids production during the process.The maximum specific growth rate(?m),the actual growth yield based on sucrose(YG) and maintenance coefficient(m) were 0.417/d,0.619g/g and 0.0206g/(g?d-1) respectively.All these outcomes could give a basis for establishing the suspension cell culture of E.ulmoides and production of the natural active components in large-scale.

Objective To define the stages of medical rescue after earthquake or tsunami disaster and their significance.Method Three stages of medical rescue were defined according to the clinical features of diseases in 3-37 days after earthquake or tsunami in Pakistan and Indonesia.The classification of diseases was based on the criteria of disaster medical rescue set by World Health Organization.Five diseases including injuries/wounds,acute upper respiratory tract infection,acute hemorrhagic enterocolitis,acute enterecolitis and other diseases of internal medicine except epidemic or suspected epidemic diseases were employed to define the stages of disaster medical rescue.Results Injuries/wounds mainly occurred in 6 days after disaster.The incidences were 61.45% to 79.52% and 61.48% to 72.35% in Pakistan and Indonesia,respectively.The incidence of acute upper respiratory tract infection reached to a considerably high rate one week after disaster.Other diseases usually appeared one week later with incidence of 33.93% to 71.11% and 31.50% to 52.11% in Pakistan and Indonesia,respectively.The rate of acute hemorrhagic enterocolitis was 2%o in Indonesia whereas 35‰of acute enterocolitis was found in Pakistan.Conclusion Three stages of disaster medical rescue could be well defined.(1)Early or critical stage(in 6 days after disaster):Treatment of injuries/wound and resuscitation was the primary step to deal with.(2)Intermediate of subaeute stage(7-30days following disaster):The incidences of various kinds of diseases increased and more medical resources were needed in order to treat the upper respiratory tract infection and to lower the disable rate,and to prevent the prevalence of epidemic diseases.(3)Later or recovery stage(1-3months after disaster):The general condition of victims became even better than that of those affected by commonly occurred local diseases,and during this period,there were shortages of medical facilities and medical personnel.Therefore,supplement of medical resources was required.The well defined stages of medical rescue have an important significance for medical rescue teams to treat victims and prevent epidemic diseases more efficiently and timely,and also provide a guidance of scientific basis for the logistics officers of local government as well as our government to make a proper and reasonable distribution of medical resources,and dispatch and arrangement of medical rescue teams.This guidance also helps to make victims re- reliant.

Background Some aboard studies showed that polyatomic pathway play an important role in the microsvasculopathy of type 2 diabetes,and sorbitol dehydrogenase (SDH) gene is involved in the pathogenesis of diabetic retinopathy(DR).There is no relevant research at home up to now.Objective This study was to investigate the correlation of sorbitol dehydrogenase (SDH) G-888C gene polymorphism with diabetic retinopathy (DR) in type 2 diabetes mellitus.Methods The SDH genotypes were determined by polymerase chain reactionreaction fragment length polymorphism (PCR-RFLP) in 187 patients with diabetes and 123 normal contrels.Patients were divided into two groups depending on the presence or absence of DR(DR:n=118;NDR:n=69).The frequencies of SDH genotype and allele were assayed and compared among these groups.This study was approved by Ethic Committee of Guangdong General Hospital.Written informed consent was obtained from each individual prior to any relevant medical procedure.Results The disease course in the DR group was significantly longer than that in NDR group(t=2.070,P=0.042),and other clinical features in both groups were non-significant (all P>0.05).The genotype frequencies in the DR group,NDR group and normal control group were 24.6%,8.7% and 8.1%,respectively,and frequencies of the G allele were 42.4%,25.4% and 29.7%,showing statistically significant differences among these three groups.The GG genotype and G allele frequencies were significantly higher in the DR group than those in the NDR group and normal control group (GG:P=0.007,P=0.001;G:P=0.001,P=0.004).There were no significant differences in the frequencies of the GG genotype and G allele between the NDB group and normal control group ( P>0. 05) as well as the proliferative DR group and non-proliferative DR group (P>0.05).Conclusion SDH G-888C gene polymorphism is associated with the development of diabetic retinopathy in southern Chinese.

Objective To analyze the drug resistance profile and risk factors for extensively drug resistant tuberculosis (XDR-TB) patients. Methods XDR-TB cases were identified by sixteen anti-TB drug susceptibility kits among inpatients with a diagnosis of laboratory-confirmed mycobacterium tuberculosis. Single-factor and Logistic analysis were used to analyze the risk factors for drug resistant of the first and second-line anti-TB drugs in XDR-TB patients. Results Resistant rate of rifampin, isoniazid and rifampicin were 100%, Resistant rate of streptomycin, rifampicin and dean, b sulfur isoniazid, levofloxacin and capreomycin were from 90% to 100%, resistant rate of kanamycin and amino salicylic acid were from 70% to 80%, resistant rate of amikacin from 60% to 70%, resistant rate of sulfur isoniazid was from 50% to 60%, resistant rate of ethambutol and moxifloxacin were from 40% to 50%, resistant rate of clarithromycin was from 10% to 20%, resistant rate of clofazimine 5.2%. 92.1% of XDR-TB patients were resistant to more than 10 anti-TB drugs, and the least of the patients were resistant to 6 anti-TB drugs.Logistic regression analysis showed the risk factors for XDR-TB first-and second-line anti-tb drugs included age ［20-40 year (OR=6.318, 95% CI:1.204-33.15, P=0.029;40-60 year (OR=4.772, 95% CI:0.973-23.392, P=0.054); 60 year (OR=41.366, 95% CI:2.909-588.265, P=0.006)］and anti-TB treatment history was retreatment(OR=28.013, 95% CI:3.357-233.766, P=0.002). Conclusions XDR-TB patients have serious drug resistance, but there were some drug treatable drug resistance types, and the risk factors mainly come from age and anti-TB treatment history.

OBJECTIVETo explore the therapeutic methods of fracture and dislocation of coccyx and evaluate its curative effects.

METHODSFrom May 2002 to March 2010,56 patients with fracture and dislocation of coccyx were divided into surgical treatment group and non-surgical treatment group. There were 7 males and 20 females in surgical treatment group with an average age of (48.1 +/- 0.6) years (ranged, 29 to 62 years), treated with open reduction and mini-plate internal fixation. There were 8 males and 21 females in non-surgical treatment group with an average age of (47.5 +/- 0.9) years (ranged, 19 to 54 years),treated with manipulative reduction. All patients were underwent X-ray examination and were finally diagnosed before treatment. Clinical symptoms and Visual Analogue Scales (VAS) of all patients were statistically analyzed before and after treatment.

RESULTSThere was no significant difference between two groups in gender, age, BMI index and VAS evaluation. All patients were followed up from 12 to 25 months with an average of 17.2 months. In surgical treatment group,there were 26 cases with I/a incision and 1 case with II/a incision; the excellent rate of clinical symptom was respectively 92.6% and 100% at leaving hospital and final follow-up; the improvement rate of VAS was 97.6% and was excellent result;internal fixtures were removed at the 1 to 2 years after treatment and no unwell symptoms occurred; VAS of all patients in the group was 0 point. In non-surgical treatment group,the excellent rate of clinical symptom was respectively 72.4% and 82.8% at leaving hospital and final follow-up; the improvement rate of VAS was 72.1% and was good result. There was significant difference in clinical results between two groups (P<0.05).

CONCLUSIONThe results indicated that fracture and dislocation of coccyx should be treated in time. For the treatment of patients with manipulative reduction failures, instability reduction by X-ray examination and serious rectal irritation, open reduction and mini-plate internal fixation can obtain satisfactory results.
