Objective This study is aimed to assess the accuracy of clinical measurement of remission and investigate the association between clinical remission and the ultrasound imaging assessment of synovitis and infla'mation and to explore the value of ultrasound imaging in the evaluation of disease activity in the tight control of rheumatoid arthritis (RA).Methods RA patients with a disease activity score in 28 joints (DAS28-ESR) ≤2.6 for at least 3 months were stratified-using a standard and more stringent DAS28 and simplified disease activity index (SDAI) remission thresholds and the corresponding clinical and ultrasound imaging measures of synovitis were recorded.In addition,a retrospective analysis of disease activity in patients was carried out.Mann-Whitney U test,x2 test and multi-factor analysis of variance of repeated measurements were used for statistical analysis.Results A total of 48 cases were recruited.Thirty-seven cases (77％) met the ACR remission criteria,29 cases (60％) fulfilled the SDAI remission criteria,and 32 (67％) cases reached 2010 ACR/EULAR Boolean-based definition of remission criteria.There was no significant differences on imaging disease activity between SDAI remission patients and those who were not in remission (GS score,P=0.38; PD score,P=0.32).Seventy-nine percent patients in SDAI remission had GS and/or PD activity,but the difference was not statistically different when compared with patients who did not reach SDAI remission (P=0.29).Sustainable remission obtained in patients who also had achieved image remission could have longer remission time (P＜0.01) Conclusion Using more stringent clinical remission criteria could help in reducing residual inflammatory activity of,but ultrasound PD activities may not be significantly reduced.Integrated clinical indicators such as physical examination and imaging tools such as ultrasound can provide more accurate assessment of disease activity and could be used to guide treatment to achieve trueremission.

OBJECTIVETo compare the efficacy and adverse reaction of chemotherapy in CHOP protocol (CT-CHOP) alone or compared with Shenqi Fuzheng injection (SFI) for treatment of moderate malignant non-Hodgkin's lymphoma.

METHODSSixty patients were divided into 2 groups, the treated group (n = 32) treated with CT-CHOP plus SFI for 5.7 cycles on average and the control group (n = 28) treated with CT-CHOP alone for 5.6 cycles on average.

RESULTSIn the treated group, 18 patients were completely remitted (CR), 4 were partially remitted (PR), 7 were unchanged (NC), 3 were progressively deteriorated (PD), with the total remission rate of 68.8%, while in the control group, 13 were CR, 4 PR, 7 NC and 4 PD, the total remission rate being 60.7%. After treatment, the levels of CD3, CD4 and CD4/CD8 increased and CD8 decreased significantly in the treated group (P <0.05). Patients' quality of life (QOL) in the treated group was improved more obviously than that in the control group (P < 0.01), and the incidence rate of adverse reaction as leucopenia, neurotoxicity, and cardiac toxicity were lower in the treated group than those in the control group (P<0.01).

CONCLUSIONShenqi Fuzheng injection combined with CT-CHOP on malignant non-Hodgkin's lymphoma can reduce the adverse reaction of chemotherapy, ameliorate the compliance of patients to chemotherapy, and improve the immune function and QOL of patients.

Objective To investigate the electrophysiological properties of layer Ⅱ/Ⅲ pyramidal neurons of the early postnatal stage rat visual cortex.Methods By using the whole cell patch-clamp recording technique combined with direct visualization of cells,we studied the passive and active electrophysiological properties as well as firing properties of layer Ⅱ/Ⅲ pyramidal neurons in acute rat visual cortical slices.Results Resting membrane potential,input resistance,membrane capacitance and membrane time constant of pyramidal neurons at postnatal days 11-13(P 11-13) were(-56.6?1.8)mV,(185.4?2.7)M?,(77.9?2.2)pF and(16.9?2.4)ms,respectively.Action potential amplitude and duration were(97.7?2.7)mV and(2.3?0.1)ms,respectively.Threshold potential was(-31.8?1.2)mV and afterdepolarizing potential was(-65.3?1.1)mV.When presented with long depolarizing current pulse of constant amplitude,most of the neurons exhibited pronounced adaptation of spike frequency.The steady-state firing frequency was(30.4?9.4)% of the first interval firing frequency.Conclusion The electrophysiological properties of layer Ⅱ/Ⅲ pyramidal neurons of the early postnatal stage rat visual cortex are not fully mature.Most of the neurons display regular firing patterns,but the degree of firing frequency adaptation is relatively small.

Objective To discuss the clinical effects of laparoscopic therapy and duodenoscopic therapy in the treatment of biliary severe acute pancreatitis.Methods A total of 140 patients with biliary severe acute pancreatitis(BSAP) in our hospital was assigned into laparoscopic therapy group(60 cases) and duodenoscopic therapy group(80 cases) according to the treatment plan,and indicators in both groups were compared,including acute physiology and chronic health evaluation(APACHE Ⅱ score),WBC,CRP,the operation time,intraoperative blood loss,hospitalization time,hospitalization fee,complication rate,cure rate,mortality rate,abdominal pain disappearing time,body temperature recovered to normal time,blood amylase recovered to normal time,amino acid transaminase(ALT) recovered to normal time,total bilirubin(TBIL) recovered to normal time,alkaline phosphatase(ALP) recovered to normal time.Results APACHE Ⅱ scores and the levels of WBC,TBIL,ALT and CRP in both groups were significantly decreased after surgery(P＜0.05),but there were no statistical differences between the two groups at the same time point after treatment(P＞0.05).The operative time and the intraoperative blood loss in the duodenoscopic therapy group were significantly less than those in laparoscopic therapy group(P＜0.05).There were no statistical differences between the two groups of hospitalization time,complication rate,cure rate,mortality rate,abdominal pain disappearing time,temperature returned to normal time,blood amylase recovered to normal time,ALT recovered to normal time,TBIL recovered to normal time,ALP recovered to normal time(P＞0.05).Conclusion In early stage,both laparoscopic therapy and duodenoscopic therapy can treat BSAP effectively,and their therapeutic effects are nearly similar.

Objective To explore the effects of difierent preoperative catheterization times to blood pressure,heart rate and occurrence rate of catheter-related bladder discomfort during postoperative emergence peiled among patients with time selecting operation.Methods 90 patients were randomly divided into three groups,30 patients in each group:the routine catheterization group(group A),the catheterization after premeditation for 15 minutes before anesthesia(group B),and the catheterization after anesthesia(group C).Physiological parameters of subjects(including systolic pressure,SBP;diastolic pressure,DBP;heart rate,HR)Were monitored pre-operatively,intra-operatively and post-operatively;catheter-related bladder discomfort was evaluated at Oh.1h,2h and 6h after operation.Results Blood pressure and heart rate at three measurement times(pre-operatively,intra-operatively and post-operatively)in group A had statistically significant meanings,respectively(P<0.05).There was no difference in group B and group C(P>0.05).The incidence of catheter-related bladder discomfort was higher in group C than that in group A and B(P<0.05).and the difference had obviously statistical meaning(P<0.05).Conclusions Group B (catheterization after premeditation for 15 minutes before anesthesia)has the least effects of blood pressure,heart rate and catheter-related bladder discomfort on patients with time selecting surgery.So catheterization after premedication for 15 minutes before anesthesia is the choice with less influence to the patients.

OBJECTIVE: To establish a 15-plex rapid STR multiplex amplification system. METHODS: Fourteen auto-chromosome loci and one sex-chromosome were selected to compare the situations of allelic losses and nonspecific amplication under different conditions. FastStart Taq DNA polymerase and DNA standard sample 9947A were used during amplification and optimization process.15-plex rapid STR amplification system was achieved by performing various experiments including selection of amplification conditions and the volume of DNA polymerase, adjustment of inter-locus balance, optimization of rapid amplification, screening of reaction buffers, selection of reaction volume, and a variety of additives. RESULTS: Using 10 μL rapid PCR system, including 1 ng DNA templates, 0.4 μL polymerase and 10xFastStart high fidelity reaction buffer, a complete and well-balance DNA profile of 15 STR loci for standard genomic DNA was obtained in 32 minutes, without the allele drop-out and non-specific amplicons. Meanwhile, 5% glycerinum, 0.01% gelatin, 0.05% gelatin and 5 mmol/L ammonium sulfate could be used as the reactive additive during the amplification procedure. CONCLUSION The 15-plex rapid STR multiplex amplification system can be used to decrease reaction time and enhance sample throughput.
