OBJECTIVETo sum up the experience in diagnosis and treatment of Fournier's gangrene and find an optimal evaluation tool for its prognosis by comparing currently used prognostic scoring systems.

METHODSWe retrospectively analyzed 16 cases of Fournier's gangrene diagnosed and surgically treated in our hospital between 2004 and 2012. Using Fournier's Gangrene Severity Index (FGSI), Uludag Fournier's Gangrene Severity Index (UFGSI), Age-Adjusted Charlson Comorbidity Index (ACCI), and Surgical Apgar Score (sAPGAR) , we obtained the prognostic scores of the patients and made comparisons among different scoring systems.

RESULTSFGSI, UFGSI, ACCI, and sAPGAR were all clinically used scoring systems. Statistically significant differences were found in the scores of ACCI and UFGSI but not in those of FGSI and sAPGAR between the death and survival groups, with the maximum area under the ROC curve and minimum standard error for the ACCI score.

CONCLUSIONBoth ACCI and UFGSI are useful for evaluating the prognosis of Fournier's gangrene. However, ACCI is even better for its higher sensitivity and specificity and easier clinical collection.

ObjectiveTo study the clinical effect of improved decortication in treatment of tuberculous empyema as well as the safety of operation.MethodsEighty-two cases who diagnosed as tuberculous empyema by pathology and operation from January 2007 to September 2010 were selected including improved decortication 44 cases,total empyema decortication 28 cases,thoracoplasty 10 cases.The operation time,peri-operative bleeding,postoperative complication and lung function recovery after 6 months operation were followed-up.ResultsAll the patients were in good recovery and there was no death in the operation for 1 year.The peri-operative bleeding in improved decortication was less than that in total empyema decortication and thoracoplasty [(56.23 ± 15.56) ml vs. (78.65 ± 23.14) and (66.92 ± 19.83) ml],and there was significant difference among them(P＜ 0.01 ).There was no postoperative complication in improved decortication,but 2 cases (7.1％,2/28) of partial lung recruitment maneuvers in total empyema decortication,1 case ( 10.0％,1/10) of extensive staxis with selective surgery in thoracoplasty.The proportion of forced vital capacity (FVC),forced expiratory volume in one second (FEV1),peak expiratory flow (PEF) turning to normal after 6 months operation in improved decortication [95.5％(42/44),93.2％(41/44),97.7％(43/44)]were higher than those in total empyema decortication[ 75.0％ (21/28 ),78.6％ (22/28),85.7％ (24/28) ]and thoracoplasty [ 80.0％ (8/10),90.0％ (9/10),80.0％ ( 8/10) ],and there was significant difference among them (P ＜0.01).There was no significant difference in the operation time among them(P ＞0.05).ConclusionImproved decortication has remarkable superiority in curing tuberculous empyema especially it is small in traumatic with less blood loss,fewer postoperative complications,lung function recovery rapidly after operation.

Objective To observe the change of the balance between regulatory T (Treg) cells and T helper 17(Th17) cells in peripheral blood of the patients with serofast syphilis .Methods From January 2010 to September 2012 ,28 patients with serofast syphilis in our department were selected into the observation group and 30 normal persons were selected into control group .Flow cytometry was used to measure the expression of Treg cells ,Th17 cells ,specific transcription factors Foxp3 and ROR-γ in the pe-ripheral blood .The comparative analysis was carried out .Results The proportion of Treg cells in the peripheral blood of the obser-vation group was (34 .02% ± 12 .31% ) ,which was higher than (21 .86% ± 8 .24% ) in the control group(P<0 .05) ,and the pro-portion of Th17 cells in the peripheral blood of the observation group was (3 .08% ± 2 .17% ) ,which was lower than (9 .13% ± 1 .96% ) in the control group(P<0 .01);the expression level of Foxp3 of CD4+ T cells was (2946 .35 ± 995 .63) in the observation group ,which was higher than (2468 .74 ± 869 .63) in the control group(P< 0 .05),and the expression level of ROR-γwas (1438 .29 ± 659 .31) ,which was lower than(1831 .25 ± 426 .37) in the control group(P<0 .05) .All above differences had signifi-cantly statistical significance .Conclusion The Treg/Th17 cell balance is abnormal in peripheral blood of the patients with serofast syphilis .This cellular immunity suppression of human body may be the reason leading to serofast syphilis .

Objective To study the association between human papillomavirus (HPV) genotypes and viral load and clinical features of verruca vulgaris.Methods Tissue samples were collected from 48 outpatients with verruca vulgaris,and DNA was extracted from these tissue samples.To determine the genotype of HPV,PCR was performed to amplify the L1 fragment of HPV with universal primers followed by bidirectional sequencing and BLAST.The genotyping results were validated by PCR with type-specific primers.Real-time fluorescence-based quantitative PCR was conducted to measure the viral load of HPV,and hematoxylin and eosin (HE) staining to observe histological changes in these tissue specimens.Results The L1 fragment of HPV was amplified from 35 out of the 48 tissue specimens.Of the 35 L1-positive specimens,32 harbored HPV 7,1 harbored HPV 57,and 2 harbored both HPV 2 and HPV 7.Multiple lesions were observed on extremities in the patient infected with HPV 57,but on the head,face and trunk in the patients coinfected with HPV 2 and HPV 7.There were no significant differences in HPV viral load or vacuolated cell number between patients with single lesions and those with multiple lesions,or between patients with a clinical course of ＜ 6 months and those with a clinical course of 6-12 months.However,HPV viral load tended to decrease one year after the onset,and there was pronounced hyperkeratosis and less vacuolated cells in lesions of long duration (more than 2 years) compared with those of short duration (less than 2 years).Conclusions HPV 7 appears to be the most common HPV genotype associated with verruca vulgaris,and HPV 7 infection usually occurs on the head and face.For verruca vulgaris of less than 1 year,neither HPV viral load nor vacuolated cell number is associated with the count or clinical course of warts.

Objective To analyse the clinical characteristics,treatments and prognosis of the chemotheray-induced lung injury in malignant hematological diseases patients.Methods 26 malignant hematological diseasespatients with chemotheray-induced lung injury were collected.The clinical characteristics,chemotherapy regimen,treatments and prognosis of the patiants were retrospectively analyzed.Results Among 26 patients,10 patients were male and 16 patients were famale.The dignosis were nonHodgkin's lymphoma (16 cases),leukemia (9 cases) and multiple myeloma (1 case).The chemotherapy regimens inducing lung injure probably were R-CHOP,R-BEACOP and BEACOP in lymphoma,while they were HA,AA,DA and IA in leukemia.The symptoms of lung injury in these patients were fever,cough,hemoptysis,dyspnea,fatigue,or asymptomatic radiological examination revealed.Pulmonary diffuse infiltration and shadows were showed in CT scan.21 cases were cured by hormone therapy,5 cases died of lung injury,2 cases died of tumor recurrence after lung injury cured.There was no effect on the quality of life in most cured patients.Conclusion The lung injury induced by chemotherapy has no specific clinical characteristics and diagnostic criteria,and it could progress rapidly to cause death.But early dignosis and early hormonal treatment can obtain good therapeutic effect.The occurrence regularity and clinical characteristics should be studied furtherly.

Objective:To analyze the characteristics of hospital infection of hematological disease, so as to provide reference for clinical therapy. Methods: Bacterial strains and antimicrobial resistance of pa-tients with hospital infection in Department of Hematology, Peking University Third Hospital from Jan. 2011 to Dec. 2013 were identified and analyzed retrospectively. The specimens were from their blood, urine, sputum, throat swabs and etc. Results:Among the total of 168 isolates of bacteria,the majority of the bacteria strains were from sputum (42. 9%);114(67. 9%) bacteria strains were gram negative and 54(32. 1%) bacteria strains were gram positive;the pathogen testing showed that 20. 8% were Pseudo-monas aeruginosa,18. 5% Escherichia coli,17. 9% Staphylococcus aureus, 9. 5% Klebsiellar pneumonia, 5. 9% Staphylococcus epidermis and 27. 4% other bacteria ;The gram negative bacilli to cefepime, ami-kacin and carbapenems showed the lowest antimicrobial resistance rates, and S. aureus showed the lowest antimicrobial resistance rates to vancomycin and linezolid. Conclusion:Patients with hemopathy are the main population of hospital infections, the gram negative bacteria are the most common pathogens. It is very important to promptly know the change in distribution of the pathogens in order to rationally select antibiotics and reduce the incidence of bacterial infections.

Objective To evaluate the value of 3.0T MRI diffusion-weighted imaging (DWI)in diagnosis and staging of cervical cancer. Methods A total of 65 cervical carcinoma patients were enrolled and performed T2 WI,DWI and LAVA-Flex dynamic contrast-enhancement before operation.MR images were analyzed by two radiologists to evaluate the staging performance.Results All the cervical cancers were detected in DWI,while three lesions were missed in T2 WI and one lesion was missed in LAVA-Flex dynamic contrast-enhanced MRI.Respectively,the accuracy of staging with DWI,T2 WI and LAVA-Flex dynamic contrast-enhanced MRI was 90.8%,78.5%and 87.7%.Accuracy of DWI was significantly higher than that of T2 WI(P =0.04),while there was no significant difference of accuracy between DWI and LAVA-Flex dynamic contrast-enhanced sequence (P =0.39).Conclusion DWI shows relatively higher accuracy than T2 WI in the staging of cervical cancer which makes it an ideal method to replace LAVA-Flex dynamic contrast-enhanced MRI for exact staging.

Septic arthritis of the sternoclavicular joint(SCJ) is a rare condition and accounts for 0.5％-1.0％ of septic arthritis.SCJ infections often require surgical intervention.Diabetes mellitus,rheumatoid arthritis,intravenous drug use,intraarticular injection and immunosuppressive disorders are predisposing factors.Staphylococcus aureus and Pseudomonas aeruginosa are the most common bacteriologies.Early diagnosis of SCJ infection requires a high index of suspicion and a confirmatory CT or MRI scan.The characteristic imaging features include intramedullary and soft tissue gas,sequestra,soft tissue swelling and destruction or widening of joint space.Management strategies have ranged from conservative antibiotic therapy to en-bloc resection of the sternoclavicular joint with or without ipsilateral pectoralis major muscle transposition.The shoulder function in most patients were well preserved.
