Objective To explore the main points of early diagnosis,the principles and the efficacy of surgical treatment of Lisfranc injury.Methods The clinical data and follow-up results of 23 cases of patients with Lisfranc injury treated from April 2004 to February 2011 (17 males,6 females,aged from 19 to 57 years old) were collected and analyzed.All patients underwent open reduction and internal fixation,among them,13cases with Kirschner wire fixation and 10 cases with screws fixation.Efficacy was evaluated in accordance with Maryland foot score.Results Twenty-one patients were followed up for 6 - 46 months with an average of (28.5 ± 2.6) months.In the last follow-up no patients has internal fixation fracture,loss of reduction and other complications.The score was 56 - 97 points with an average score of ( 86 ± 8 ) points.The results showed excellent in 6 cases,good in 10 cases and fair in 3 cases,good rate was 76.2％.Conclusion Lisfranc injury can be diagnosed by early signs and symptoms,and can be confirmed by combining with radiographic examination.Lisfranc injury should be treated with open reduction and internal fixation with Kirschner wire or screw,both of the two fixation methods can achieve good results.

Periprosthetic infection is one of catastrophic complications which appear anytime after joint arthroplasty. Resear?ches show that the patients′risk factors are the keys to affect prosthetic joint infection after primary hip and knee arthroplasty. The au?thor summarized new study progress about risk factors for prosthetic joint infection after primary hip and knee arthroplasty at home and abroad. To investigate risk factors for prosthetic joint infection, the condition were analyzed by investigator from the following three as?pects:the patients′features, comorbidity, and preoperative medication.

The late stages of the HIV-1 replication cycle are important to the overall replication cycle. During the late stages, HIV-1 replication undergoes the processes of assembly, release, and maturation, resulting in the production of a mature virus particle capable of infecting a new target cell. The structural protein Gag and its related gene (protein) play a central role in these pathways. The different regions of Gag worked in concert to drive production of a mature infectious particle through protein-protein, protein-RNA and protein-lipid interactions. The designed drug aimed directly at these stages can efficiently block the maturation and infectivity of HIV-1. In this article, the role of structural protein Gag and related gene (protein) in late stages of the HIV-1 replication cycle and related inhibitors is reviewed.

The pre-examination process is the first key step in the total testing process of clinical laboratories.Specimen acceptability is an important indicator to measure the quality of pre-examination.In order to identify the risks and the root causes in the process , establishment and monitoring of quality indicators about specimen will effectively control the risks , enhance the acceptability of specimens , promote the improvement of pre-examination quality and finally get the aim of assuring patients′safety.

Objective To investigate the diagnosis and treatment of pseudomyxoma peritonei(PMP).Methods[WT5”BZ] Retrospective study was made on 8 cases of PMP treated in our department.Results Main clinical presentations included abdominal pain,distention,mass and wasting.Ultrasonography showed heterogeneous ascites in 2 cases and elevated CEA level in 4 cases.All patients underwent surgery.Primary tumour was identified in the appendix in 7 cases and in the colon in 1 case.Surgical procedure included resection of primary tumour, omentectomy ,removal of mucinous ascites and combined resection of organs involved.Postoperative adjuvant chemotherapy and /or radiotherapy was added to 6 cases.All patients were followed up and 5 year survival rate was 50%(4/8),10 year survival rate was 13%(1/8).Conclusions 1 .PMPisarareconditionanddifficulttodiag nosisbeforesurgery ,ultrasonographyandCEAmayhelpinmakingadiagnosis .2 .Beingalow gradecarcinomaand infrequentmetastasis,PMPisoftenresponsivetorepeateddebulkingfollowedbyadjuvanttherapy,hencehasafa vorablelong termsurvival.

Objective To discuss the feasibility of application of laryngeal mask airway(LMA)in pediatric corrective surgery of lingual frenum. Methods Retrospective study was conducted of 42 chil-dren using laryngeal mask airway in selective surgical correction of lingual frenum under general anesthe-sia in our hospital. The childrenˊs vital signs were recorded at five different time points:baseline before an-esthesia(T0),consciousness and eyelid reflex disappear just after anesthesia induction(T1),time right af-ter the LMA insertion(T2),3 ~ 5 min after beginning of operation(T3),and time at the extubation(T4). The success rate of first LMA insertion and the number of changing to other ventilation way were recorded. The shift of LMA and postoperative sore throat within 24h were recorded. Results The success rate of the first LMA insertion was 85. 71% . Intraoperative laryngeal mask airway leak and shift did not occur and the ventilation was also good. Vital signs of the children were stable during operation. The incidence of postop-erative sore throat was 15% within 24h. As to the heart rate,the vital signs of baseline T0 were significant-ly different from other time points(T1,T2,T3,T4). After the anesthesia,there were no significant differ-ences in heart rate among different time points(T1,T2,T3,T4). Compare with T2 and T3,the values of partial end expiratory pressure of CO2 at T0,T1,and T4 were significantly different. Compare with T0,the values of mean arterial pressure at T1,T2 and T3 were significantly different,but there was a significant difference in mean arterial pressure between T1 and T4. As to the pulse oxygen saturation,all the values were above 95% . Conclusion Laryngeal mask airway is a supraglottic airway management method. The advantages of fewer haemodynamic changes and postoperative complication are confirmed. It is feasible and safe for securing the airway in surgical correction of lingual frenum.

OBJECTIVE:To compare the relative bioavailability between2loratadine tablets(LORAX and LORAS)in human body.METHODS:22healthy male volunteers were enrolled to receive oral single dose(20mg)of either LORAX or LORAS tablets by crossover way,plasma concentrations of loratadine were determined by HPLC and pharmacokinetic param-eters were calculated by3p97program.RESULTS:The pharmacokinetic parameters of LORAX vs.LORAS were the fol-lowing,t 1/2Ke (3.03?0.98)h vs.(2.65?0.81)h;C max (8.59?6.70)vs.(9.59?8.22)ng/ml;t max (1.08?0.41)h vs.(1.21?0.28)h;AUC (0～t) (27.29?24.54)vs.(27.92?20.64)(ng?h)/ml.The relative bioavailability of LORAX was(100.63?14.27)%.CONCLUSION:2loratadine tablets were bioequivalent.
