Objective To investigate the value of lumbar puncture in the diagnosis of subarachnoid hemor-rhage of aneurysms .Methods The clinical data of 13 patients diagnosed negative by computer tomography(CT) scanning and then as subarachnoid hemorrhage (SAH) followed by lumbar puncture and as aneurysms by catheter digital subtraction angiography(DSA) were retrospectively analyzed.Results The positive rate was 100% by lum-bar puncture.Conclusion Lumbar puncture is of great significance in the diagnosis of subarachnoid hemorrhage of aneurysms, which should be applied reasonably.

Objective To screen the plasma differential expressed proteins in patients with Crohn's disease(CD)and ulcerative colitis(UC)using surface-enhanced laser desorption ionizationtime of flight mass spectrometry,and to establish decision trees algorithms.Methods The plasma samples from 24 UC patients,25 CD patients and 25 healthy controls were analyzed with CM10 protein chip.The proteomic spectra of CD,UC and inflammatory bowel disease(IBD)were compared with controls respectively.The differential proteins that significantly altered expression levels were selected to establish decision trees algorithms of CD.UC and IBD and then blind validations were tested.Results In the range of m/z 2000-30 000,differential expressed proteins that changed at least 2-fold between CD and controls were 9.between UC and controls were 5,and between IBD and controls were 11(P＜0.05).The software automatically picked up the m/z 8208 and 8837 as decision trees algorithms for differentiating CD from controls and m/z 6985 for differentiating UC from controls as well as m/z 8208,1752,28840 and 1702 for differentiating IBD from controls.The sensitivities of decision trees algorithms for CD,UC and IBD were 96%,82%and 91%respectively,and the specificities were 100%,85%and 100%respectively.Conclusions The protein of m/z 8208 which has high sensitivity in differentiating CD from controls is worthy of further study.

Objective:To evaluate the predictive value of the UK Myeloma Research Alliance Risk Profile(MRP)score based on clinical outcomes in elderly patients with newly diagnosed multiple myeloma(NDMM).Methods:Patients aged ≥65 years with NDMM in our hospital from March 2018 to September 2021 were divided into three groups with low, medium and high risk according to MRP scores.Their therapeutic efficacy, adverse effects, and survival were analyzed.Results:A total of 63 NDMM patients were enrolled with median age of 69 years(65-84 years)and median follow-up of 13.3(1.2-43.4)months.Based on MRP score, there were 22 patients in the low-risk group, 13 cases in medium-risk group, 28 patients in the high-risk group.The median progression-free survival(PFS)time of the three groups was 38.4, 25.1 and 21.2 months respectively, and the estimated 2-year PFS rate was 83.9%, 60.0%, and 45.6%, respectively(all P=0.177). The estimated 2-year overall survival(OS)rate was 100.0%, 90.0%, 74.6%, respectively(all P=0.049). Among patients with grade 2 or above hematological adverse events, there were 20 cases(71.4%), 7 cases(53.8%)and 8 cases(36.4%)in the high-, medium-and low-risk groups, with statistically significant differences( χ2=6.154, P=0.046). Among patients with grade 3 or higher non-hematological adverse events, there were 17 cases(60.7%), 5 case(38.5%)and 5 cases(22.7%)in the high-, medium-and low-risk groups, with statistically statistical significance( χ2=7.389, P=0.025). The patients experiencing interruption, delay or replacement of chemotherapy regimen were 6 cases(46.2%)and 19 cases(67.9%)in the medium-and high-risk groups, which were higher than in the low-risk group(31.8%, χ2=6.543, P=0.038). Conclusions:It is feasible to conduct MRP score in elderly NDMM patients.The MRP score can be used to predict the adverse events of chemotherapy, etc, and has certain value for the prognosis evaluation of patients.

To explore the value of items for the Chinese version of Dizziness Handicap Inventory (DHI) in differential diagnosis of benign paroxysmal positional vertigo (BPPV) in patients with vertigo or dizziness first coming to the outpatient clinic.
 Methods: A total of 322 patients with vertigo or dizziness, who came from Nanfang Hospital, Southern Medical University, were enrolled from April 2016 to February 2017. The Chinese version of DHI and Visual Analogue Scale (VAS) were completed by themselves. After detailed vestibular function examination, the patients were divided into a BPPV group, a normal vestibular group, and a abnormal vestibular group.
 Results: The score of DHI-2 in the BPPV group was 5.52±2.10, which was higher than that in the normal vestibular group (3.94±2.91)(t=3.847, P<0.01) and the abnormal vestibular group (4.17±2.74)(t=4.149, P<0.01). There were significant differences in the DHI-2 among the 3 groups (F=9.870, t=4.515, P<0.01). The score of DHI-item 13 in the BPPV group was 3.09±1.39, which was higher than that in the normal vestibular group (1.97±1.63)(t=4.515, P<0.01) and the abnormal vestibular group (1.95±1.70)(t=5.305, P<0.01). There were significant differences in the DHI-item 13 among the 3 groups (F=16.402, P<0.01). There was significant difference in VAS scores among the 3 groups (P<0.05). However, the t-test analysis showed that there was significant difference between the BPPV group and the vestibular abnormal group (P<0.05), while there was no significant difference between the BPPV group and the vestibular normal group (P>0.05).
 Conclusion: DHI-2 and DHI-item 13 should be included in the inquiry of disease history at the time of first diagnosis, which can be used to identify patients with BPPV quickly and effectively.
