OBJECTIVETo investigate the clinical characteristics of Segond fracture combined with injuries, and to explore the operative method and opportunity.

METHODSFrom June 2010 to December 2014, 10 patients with Segond fracture were treated. There were 10 males, ranging in age from 26 to 69 years old, with a mean of 42 years old. Under arthroscopy examination within 7 to 10 days after injury, 6 patients had compete rupture of anterior cruciate ligament and meniscus injury; 2 patients had tibial avulsion fractures of the ACL combined with meniscus injury. At 4 to 8 weeks after injury, 2 patients were performed with arthroscopy examination; 1 patient had complete rupture of anterior and posterior cruciate ligament combined with meniscus injury; and the other patient had complete rupture of anterior cruciate ligament alone. All the patients with cruciate ligament rupture were treated with reconstruction of cruciate ligament; 9 patients had meniscus injuries were treated with menisus plasty or suture; and 2 patients had tibial avulsion fractures of the ACL were treated with non-absorbable Ethicon suture fixation under arthroscopy. After operation, the Lysholm scoring system was used to evaluate clinical effects.

RESULTSEight patients were operated within 10 days after injury, the knee joints swelling was obvious at the 3rd day after operation, and blood oozing was found by joint puncture. These 8 patients did out-of-bed activity with assistance at 1 week postoperatively. Other 2 patients performed operation in 4 to 8 weeks after injury without knee joint obvious swelling at the 3rd day after operation, and no blood oozing was found by joint puncture. These 2 patients did out-of-bed activity with assistance after 3 days postoperatively. All the patients were followed up, and the duration ranged from 12 to 24 months, with an average of 18 months. Postoperative Lysholm score of all patients was higher than preoperative scor, and the results were satisfactory.

CONCLUSIONFor Segond fractures, firstly, it is important to gain early diagnosis for treatment. Secondly, it is often associated with the rupture of anterior cruciate ligament and meniscus injuries, and the best time of cruciate ligament rebuilding and meniscus repairing maybe between 4 to 8 weeks after injury. Thirdly, personalized treatment should be chosen according to different complications.

Objective To explore the changes of plasma brain natriuretic peptide(BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)of sepsis combined with myocardial injury in newborns.Methods According to neonatal sepsis treatment program,45 cases of sepsis newborns in NICU of the Second Hospital in Lanzhou University from Jul.2007 to Jun.2008 were collected.According to the myocardial injury diagnostic criteria,45 cases neonatal sepsis were divided into myocardial injury group(n=22) and non-myocardial injury group(n=23).Myocardial injury group was also divided into congenital heart disease group and non-congenital heart disease group accor-ding to echocardiography.At the same time,30 healthy newborns were collected as healthy control group.Every newborns were tested the level of plasma BNP,NT-proBNP,creatine kinase-MB(CK-MB) and cardiac-troponin I (cTnI).Results There were significant difference between myocardial injury group,non-myocardial injury group and healthy control group in the levels of plasma BNP,NT-proBNP,CK-MB and cTnI,those in congenital heart disease group were higher than those in non-myocardial injury group and the healthy control group(Pa0.05).Conclusions BNP and NT-proBNP can be early used to diagnose myocardial injury and heart failure of neonatal sepsis associated with CK-MB and cTnI.In NICU,infants with sepsis should normally test BNP and NT-proBNP in order to early diagnose myocardial injury of neonatal sepsis.

Objective: To analyze the long-term prognosis of re-operation in patients with functional tricuspid regurgitation (FTR) after left sided valve replacement (LSVR) and hence evaluate the optimal timing of mentioned re-operation. Methods: A total of 59 FTR patients who had re-operation after their prior LSVR in our hospital from 1999-01 to 2013-01 were analyzed. The clinical information and post-operative follow-up results were recorded in all patients. Results: There were 5/59 (8.5%) patients died in peri-operative period and the overall post-operative mortality was 11.9% (7/59). The follow-up data of 54 survivors were available for the mean time of 51.1 (21-188) months. There were 19/54 (35.2%) patients suffered from MACE and 30 (55.6%) were beneifted by improved cardiac function. Uni-variable analysis indicated that pre-operative NYHA class IV (P=0.008), pre-operative right ventricular (RV) dysfunction (P=0.037), concomitant left-sided redo-operation (P=0.017) and TVR operation (P=0.002) were associated with all cause mortality of tricuspid re-operation. Multi-variable Cox regression analysis showed that pre-operative RV dysfunction was the only independent risk factor of long term MACE-free accumulating survival rate (HR=3.0, 95% CI 1.11-8.2,P=0.031); while TVR operation (HR=12.8, 95% CI 1.53-107.02,P=0.019) and pre-operative NYHA class IV (HR=5.3, 95% CI 1.20-24.51,P=0.032) were the independent risk factors for long-term mortality in patients after tricuspid re-operation. Conclusion: Patients with compensatory RV function showed better long term prognosis after secondary tricuspid operation. Aggressive re-operation before the occurrence of right ventricular dysfunction could be beneficial for relevant patients.

Objective To investigate the trend of antimicrobial resistance and the prevalence of resistant genes in Pseudomonas aeruginosa strains isolated from Hangzhou First People's Hospital.Methods Antimicrobial susceptibilities of 1489 Pseudomonas aeruginosa strains isolated from 2003 to 2007 were statistically analyzed using WHONET.MICs of 11 antimicrobisis to 36 multi-drug-resistant Pseudomonas aerugionosa strains were determined by agar dilution method.Genes of β-lactamases(BLA)and aminoglycoside-modifying enzymes(AMEs)were detected by PCR and the PCR products were sequenced.Results The resistant rates to aztreonam,imipenem,ceftazidime,cefepime,piperacillin,piperacillin/tazobactam.cefoperazone/sulbactam,ciprofloxacin,levofloxacin,gentamicin and amikacin were increased from 13.4%,10.6%,8.7%,7.9%,12.7%,12.7%,6.7%, 15.8%,20.5%,24.7% and 10.9%in 2003 to 35.3%,40.9%,18.4%, 32.4%,32.9%,32.0%,21.9%,37.8%,38.6%, 39.4% and 34.8% in 2007.respectively.Hish MICs of 11 antimicrobiMs for multi-drug resistant Pseudomonas aerouginosa were determined with MIC90≥128 μg/mL.In 36 multi-drug resistant Pseudomonas aeruginosa strains,21(58.3%)strains carried β-lactamase genes and 32 strains(88.9%)carried aminoglycosidemodifying enzyme genes,while the deletion rate of oprD2 was 80.6%(29/36).Conclusions The resistant rates to common antibiotics of Pseudomonas aeruginosa have increased.resulting in multi-drug resistance.Genes of β-lactamases and aminoglycoside-medifying enzymes are prevalent in multi-drug resistant Pseudomonas aeruginosa strains,with the common deletion of oprD2.

Objective To investigate clinical presentations,laboratory examinations,magnetic resonance imaging (MRI) appearances and treatment of hypertrophic cranial pachymeningitis (HCP).Methods The clinical data of 13 patients with HCP receiving comprehensive therapy in Huashan Hospital from January 2007 to January 2013 were analyzed retrospectively.Results The onset of HCP was mostly chronic with an average duration of 26.7 months.The main clinical manifestations of the 13 patients were chronic headaches (12/13) and cranial nerve paralysis (12/13).Inflammation markers and cerebro-spinal fluid (CSF) protein levels increased in patients with HCP and gradually became normal after the treatment.The MRI demonstrated local or diffused thickened dura located in tentorium (10/13),falx cerebrum (5/13),frontal lobe (4/13),temporal lobe (7/13) and parietal lobe (4/13).The signal intensity was isointense on T1-weighted MR images and hypointense on T2-weighted MR images.Enhanced MR images showed conspicuous enhancement of the dural edges.Corticosteroid therapy improved the clinical symptoms in 12 of 13 patients.Conclusions HCP typically causes headache and paralysis of multiple cranial nerves.Enhanced MRI shows characteristic manifestations.At present corticosteroid therapy is the treatment of choice followed by immunosuppressive agent and radiotherapy.

Objective To investigate the most sensitive methods for diagnosing spontaneous internal carotid artery dissection (sICAD) and spontaneous vertebral artery dissection (sVAD) respectively,for the sake of earlier and more accurate diagnosis.Methods Consecutive patients with sICAD and sVAD who visited the Department of Neurology and Radiology,Huashan Hospital Affiliated to Fudan University during 2008-2013 were retrospectively reviewed and the sensitivity of CT angiography (CTA),magnetic resonance T1-weighted fat-suppressed images (MR T1-FS) and digital subtraction angiography (DSA) for the diagnosis of sICAD and sVAD was compared.Results Eighty patients (62 male,18 female; mean age (45.7 ± 11.9) years) were included in the study.There were 99 arterial dissections in total,45 cases of sICAD,52 cases of sVAD and 2 cases of spontaneous middle cerebral artery dissections.The sensitivity of CTA,DSA and MR T1-FS for diagnosing sICAD was 97.5％ (39/40),90.0％ (36/40) and 69.6％ (16/23) respectively,while for sVAD was 89.8％ (44/49),84.6％ (44/52) and 100.0％ (27/27) respectively.Conclusions sICAD and sVAD have significant differences in many aspects including diagnostic strategies.CTA and MR T1-FS seem to be the most sensitive methods for the diagnosis of sICAD and sVAD respectively.Although DSA has been considered as the gold standard for the diagnosis of artery dissection,this imaging technique does not allow analysis of artery wall thickness,thus also has limitations.It is likely that the diagnostic sensitivity will be improved by combining CTA and MR T1-FS.

Objective To explore the effects of different vitamin A(VA) levels on thyroid cells apoptosis and its gene expression of mice taking excessive iodine. Methods Kunming mice were randomly divided into 6 groups according to body weight 3 weeks after born: normal control(NI) group, high iodine(HI) group, low vitamin (LVA) group, high iodine plus low vitamin A(HI+LVA) group, high iodine plus vitamin A1 (HI+VA1) group, high iodine plus vitamin A2(HI+VA2) group. The VA was given in food(4000,4000,0,0,8000,16 000 U/kg), and the iodine was given as potassium iodate in water (I-:50,3000,50,3000,3000,3000 μg/L). The apoptosis was tested using in situ end labehng(TUNEL) method. Reverse transcription polymerase chain reaction (RT-PCR) were used to measure the level of mRNA of apoptosis gene(Fas, FasL, Bcl-2) in tissues. Results Apoptotic index measured by TUNEL method was rising along with the mice age. Compared to NI group[(14.09±5.68)%], apoptotic index was significantly increased in HI[(20.91±9.57)%], HI+LVA[(20.29±9.90)%]and HI+VA2 [(19.51±8.25)%]groups in the three months(P < 0.05). Compared to NI group[(16.80±9.90)%], apoptotic index was significantly increased(P < 0.05) in HI[(23.22±8.58)%],LVA[(22.56±6.17)%],HI+LVA [(25.99±9.62)%],HI+VA1 [(21.65±7.74)%]groups in the six months. Compared with the NI group(Fas: 1.29±0.25,1.27±0.26; FasL: 1.60±0.13,1.65±0.13), the mRNA levels of Fas and FasL in HI group(Fas: 1.57±0.36,1.49±0.35; FasL: 1.85±0.46,1.84±0.32) were increased, but the differences were not remarkable(P > 0.05) in the three and six months. Compared with the HI group, the mRNA levels of Fas in HI+ VA1, HI+VA2(1.33±0.35, 1.30±0.26) groups were decreased to the level in NI group in the six months. The mRNA levels of Fas and FasL were not different (P > 0.05) between HI+LVA(I.60±0.27,1.88±0.46) and HI groups in the three months. The mRNA levels of Bcl-2 were not remarkably differences in the three months (1.05±0.19,0.96±0.33,0.95±0.26,1.18±0.27,1.10±0.19,0.98±0.36, all P > 0.05), and in the six months (1.35±0.28,1.60±0.25,1.48±0.18,1.71±0.26,1.66±0.29,1.56±0.35, all P > 0.05). Conclusions Excessive iodine can cause thyroid cells apoptosis in mice. Supplementation of suitable amount of VA can regulate the levels of the apoptosis-related genes expression, and partly antagonize the apoptosis caused by high iodine.
