Peripheral T-cell lymphomas (PTCLs) are a kind of non-Hodgkin's lymphoma (NHL),which arise from heterogeneous mature T-lymphocyte and include a variety of different subtypes.Compared with B-cell lymphoma,PTCLs are characterized by a lower incidence,resistance to conventional chemotherapy,widespread dissemination,a higher recurrence rate and unfavorable prognosis.At present,the standard first-line treatment regimens have not yet been developed for PTCLs.Though,there are many studies and trials about new drugs and novel intensive regimens,which improve the clinical curative effects and prognosis of PTCL patients significantly.In this paper,the progress of first-line treatment regimens of patients with different PTCL subtypes was reviewed.

0.05).(4) There was significant correlation between CD62p and CD63 ( P 0.05). Conclusions Patients with cerebral infarction show evidence of enhanced platelet activation and increasment of MPV and MAR,which may relate to the pathological process of cerebral infarction. Moreover MPV and MAR can reflect the clinical severity of cerebral infarction better than PLT. Anti-platelet aggregation treatment should be further taken in patients with cerebral infarction.

Object To probe into the objectivity and authenticity of four properties (cold, heat, warm, and cool) of raw Coptidis Rhizoma (RCR) and their preparations from biophysics and biochemistry. Methods Microcalorimetry was used to obtain the metabolic growth power-time curve of bacteria affected by the total alkaloid in different preparations of RCR and biothermokinetic parameters. Combined with the records of ancient herbal literatures, the influence of properties by different preparations to RCR were synthetically evaluated. Results All the effective total alkaloid in different preparations of RCR can restrain the Escherichia coli growth and metabolism in different level. Drugs, such as Coptidis Rhizoma Stir-fried with ginger juice (CRGJ), Coptidis Rhizoma stir-fried with wine (CRW), and Coptidis Rhizoma stir-fried with Fructus Evodiae (CRFE), with a little Warm Property can decrease the multiplication rate constants of E. coli index and increase heat output in growth metablism remarkably, while the drugs, such as RCR, Coptidis Rhizoma stir-fried with vinegar (CRV), and Coptidis Rhizoma stir-fried with gallbladder juice (CRGBJ), with a little Cold Property can decrease the multiplication rate constants and increase heat output a little. There was a stable difference between them. Conclusion Microcalorimetry is a new and useful mean for the study of the properties of tradition Chinese medicine.

Objective:To investigate the structure of alveolar bone around incisors in patients with verical facial type of skeletal ClassⅡ by CBCT.Methods:60 skeletal Class Ⅱ patients were divided into low angle,average angle and high angle cases(n =20)by FMA.CBCT scanning was made and the thickness of the labial and lingual alveolar bone around the incisors in each subject was meas-ured.The measurements were analyzed using ANOVA.Results:The total width of alveolar bone at the root apical level of maxillary and mandibular incisors,the lingual thickness of alveolar bone at the root midpoint of maxillary incisors and labial thickness of alveolar bone at the root midpoint of mandibular incisors in the high angle cases were thinner than that in the average and low angle cases(P <0.05),but there was no significant difference in labial thickness of alveolar bone at the crest among 3 groups.Conclusion:The alveo-lar bone thickness around incisors of high angle patients is thinner,more attention should be paid for the alveolar bone absorpation and tooth root exposure in these patients.

Objective To observe the changes of respiratory musc]e strength by traditional Chinese medicine combined with cholinesterase inhibitors in myasthenia gravis (MG) patients.Methods Thirty-four cholinesterase inhibitor-resistant patients,of them 14 were MG patients with stage Ⅰ ,and 20 were stage Ⅱ ,were treated with bromide dimethylcarbamate ( 360-480 mg/d ).Traditional Chinese potion were administered in those without effectiveness,and the dosages of bromide dimethylcarbamate decreased with Traditional Chinese potion lasting for 4-6 months.Vital capacity ( VC ),maximal voluntary ventilation ( MVV ),maximal inspiratory pressure ( PIM ),maximal expiratory pressure ( PEM ),respiratory centre driving pressure ( P0.1 ),residual volume ( RV )were measured before and after treatment.Results The amelioration of VC,MVV,PIM,PEM,P0.1 ,RV,respiratory muscle strength and other indicators of 34 MG patients were not obviously after treatment with cholinesterase inhibitor alone ( P ＞ 0.05 ).After treatment with traditional Chinese medicine combined with cholinesterase inhibitors,VC,MVV,PIM,PEM ( before treatment:76.66% ± 18.59%,68.03 % ± 10.45 %,43.25 % ± 18.16%,21.75 % ±14.44% ) increased significantly in all 34 MG patients( after treatment:86.91% ± 14.87% ,75.11% ± 11.17%,52.66% ±20.32% ,28.56% ± 10.06% ) ( P ＜ 0.05).RV decreased from 164.94% ± 67.97% to 143.16% ±79.21% (P ＜0.01 ),and respiratory muscle strength,endurance and other indicators significantly improved (P ＜0.01).PIM(65.80% ±28.03% to 52.66% ±20.32%),and PEM (37.03% ±20.57% to 28.56% ±10.06%)improved more significantly in group stage than in group stage (P ＜0.01 ).Respiratory muscle endurance in stage Ⅰpatients ( 108.71% ± 17.56% ) improved significantly than stage Ⅱ patients (96.01% ± 14.12% ,P ＜ 0.01 ).Conclusions Traditional Chinese medicine combined with cholinesterase inhibitors could effectively improve the lung function and respiratory muscle strength in patients with resistance of the cholinesterase inhibitors.The improvement of lung function,respiratory muscle strength were more obviously in stage Ⅰ patients than in stage Ⅱ patients.Respiratory muscle strength and endurance were improved greater in stage Ⅱ than in stage Ⅰ patients.

Objective To study the sedation and amnesia of midazolam in patients with different ages of lumbar epidural anesthesia . Methods From January to July 2015, 235 patients in the first affiliated of xian jiaotong unniversity,who were implemented abdominal surgery under combined spinal epidural anesthesia and American Society of anesthesiologists (ASA) grade was I-II , were divided into three groups:young group (n=70); middle-aged group (n =82); elderly group (n =83).Intraoperative continuous monitoring of respiratory and circulatory function index,and recorded MAP,SpO2, HR before and 5, 15, 30 min after injection.ResuIts MAP, HR and SpO2 of three groups were compared with the same time points pre-and post used of midazolam, there was no significant difference among indicators.; Compared with the same group at different time points, MAP(FYG =9.2547,FMG =12.8181,FOG =17.77)和 SpO2 (FYG =190.3835,FMG =196.2393,FOG =270.5609),there were significant difference.The difference was not statistically significant between HR group and the same group at different time points and forgetting degree and sedation score , but compared with OG,there were significant difference(P<0.05).The total number of adverse reactions in YG group and MG group was less than that of OG group(X2 =11.2516,X2 =10.4491, P<0.05).ConcIusion The effect of the same dose of midazolam on sedation and amnesia in patients with different ages of lumbar epidural anesthesia is different, and the degree of the effect of the elderly patients is significant,but will produce more adverse reactions.Therefore, in the combined spinal epidural anesthesia,it is necessary to consider the patient's individual differences, rational use of sedative and narcotic drugs.

Objective To explore a method for establishing the hamster model of Clostridium difficile-associated diarrhea (CDAD)and the indicators for its evaluation.Methods Clindamycin was administered to hamsters subcutaneously (day 1),and 24 h later infected with C.difficile clinical isolates KH1 (ribotype 027,106-108 CFU/mL)or SH9 (ribotype 001 ,108-1010 CFU/mL)by gavage.Animals were observed for CDAD symptoms such as diarrhea,weight loss and death.At the end of ob-servation period (day 7 or death),the cecum was collected from each animal for histological evaluation of inflammation.Results Following a single dose of 100 mg/kg clindamycin subcutaneously,all the animals challenged with KH1 (108 CFU/mL)devel-oped diarrhea and then died within 5 days.All the hamsters challenged with SH9 (1010 CFU/mL)developed diarrhea as well but only 66.7% died at the end of observation period.Among other groups,only one or none developed diarrhea and then died. The symptoms of hamsters with diarrhea included loose stool,wet tail and weight loss.On histological examination,conges-tion,hemorrhage and neutrophil infiltration of the mucosa were observed in the hamsters died of CDAD.Conclusions We have successfully established a hamster CDAD model that allows for future investigations.

Objective To investigate the value of three-dimensional CT volume rendering in predicting ARDS following pulmonary contusion and identifying high-risk patients.Methods Seventy-one cases of pulmonary contusion (AIS ＞ 2 points) confirmed by chest CT during an emergency admission between July 2010 and June 2011 were enrolled.Using computer-generated three-dimensional reconstruction,contusion volume was measured and expressed as a percentage of total lung volume.The admission data,such as blood gas analysis results,systolic arterial pressure,hematocrit,AIS,ISS,and injury distribution,were prospectively collected.Independent predictive factors of ARDS following pulmonary contusion was identified using logistic regression analysis and further estimation on accuracy and value of the predictors were performed.Influence of contusion volume percentage on clinical outcomes was detected.Results Of all,mean contusion volume percentage was (22.07 ± 14.50)％ (range,5.60％-61.00％),which was not strongly correlated to the admission PaO2/FiO2 ratio (R2 =0.059).ARDS and infection were diagnosed in 31 cases and 25 cases respectively.PaO2/FiO2 ratio and contusion volume percentage were independent predictive factors of ARDS after pulmonary contusion.The best cut-off of contusion percentage in predicting ARDS development was 21.5％ with a specificity of 80.0％,sensitivity of 71.0％,positive predictive value of 73.3％,and negative predictive value of 78.1％.Conclusion Three-dimensional CT volume rendering technique allows quantification of pulmonary contusion and identification of patients at high risk of ARDS,to whom further treatment may be directed.
