OBJECTIVE:To evaluate the cost-effectiveness of Tanreqing injection in treating children's viral pneumonia.METHODS:In this retrospective study,sixty children with viral pneumonia were randomly assigned to receive Tanreqing Injection(treatment Group,n=30)or Ribavirin(control Group,n=30).The clinical effects and adverse drug reactions(ADRs)of the two groups were compared,and the cost-effectiveness analyses were performed.RESULTS:The effective rate was 100% in the treatment Group versus 80% in the control Group;the incidence rate of ADRs was 3.33% vs.13.33%;the cost was 297.88 vs.399.95 yuan;and the cost-effectiveness was 297.88 vs.499.94,all showing significant differences between the two groups(P

Objective To assess the clinical efficiency of percutaneous coronary intervention (PCI) on cor-onary artery disease patients with complicated lesions (CAD-CL). Methods A total of 252 patients of CAD-CL treated with PCI from August,2002 to September,2009 were enrolled in the study. Clinical data on prognosis e. g, success rate, complication occurrence and major adverse cardiac events were observed. Results Two hundred and forty-four patients with CAD-CL(including chronic obstruction, bifurcation lesion, long lesion and restenosis) were implanted stent successfully(96.83%), with no residual stenosis or residual stenosis less than 20%. There were col-lateral obstructions in 32 patients and artery secret compartment in 48 patients, and restenosis in 15 patients. One patient of acute anterior myocardial infarction complicated by cardingenic shock was in low blood pressure status after two anterior descending artery stent placement, and died after temporary pacemaker implantation and other positive rescue measures. One patient occurred subacute stent thrombosis on the third day, and was cured after occlusive vas-cular recanalization through emergency PCI. Conclusions Percutaneous coronary intervention for coronary artery disease patients with comphcated lesion is safe and effective.

Objective To study the appropriate neck irradiation volume for neck lymph nodenegative nasopharyngeal carcinoma patients by Meta-analysis.Methods The related references published from Jan 1990 to Jun 2013 were searched in Pubmed,Embase,Cochrane and Wangfang Databases.The qualified references for enrollment criteria were screened and the relative data were collected.The OR (Odds ratio) value by fixed effect model was used to evaluate the data for patients who received radiotherapy between the upper neck and whole neck irradiation.The endpoints including 5-year neck local control rate (LCR),neck-in-irradiation LCR,and neck-outsides-irradiation LCR.Results Five qualified references were screened and belonged to respective research.There enrolled 1 333 patients,including 970 patients who received the upper neck irradiation and 363 patients who received the whole neck irradiation,respectively.The forest plots revealed that there were no significant differences for 5-year neck LCR,neckin-irradiation LCR,and neck-outsides-irradiation LCR for patients received radiotherapy between the upper neck and whole neck irradiation.These OR values were 0.89 (95％ CI:0.41-1.94),1.29 (95％ CI:0.58-2.88) and 0.42 (95％ CI:0.07-2.36),respectively.Conclusions The Meta-analysis results suggest that irradiation to the upper neck for neck lymph node-negative nasopharyngeal carcinoma can be appropriate.

Objective To assess the differences in delineation of organs at risk (OAR) and dosimetry between junior and senior physicians during intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC) and to evaluate the role of specific training in reducing the differences.Methods Sixteen patients newly diagnosed with NPC were selected in the study.The OAR was delineated separately by three junior physicians and three senior physicians,and the geometric and dosimetric differences were assessed relative to the reference OAR.Delineation was performed again for the two OARs with the biggest difference after specific training in the two groups of physicians,and the differences were evaluated again.The difference was determined by paired t test.Results The maximum dose differences (Dmax) of OAR in the junior and senior physicians were (2.33 ± 12.06) ％ (-48.06％-137.82％) and (0.09 ± 4.72) ％ (-49.54％-42.96％),respectively (P =0.039),and the difference in the optic chiasm was the greatest ((5.85 ± 19.63) ％ ∶ (1.36 ± 4.64) ％,P =0.042).The mean dose differences (Dmean) of OAR in the junior and senior physicians were (3.10 ± 8.07)％ (-46.76％-59.76％) and (-0.93 ± 2.03) ％ (-45.54％-35.69％),respectively (P =0.021),and the difference in the parotid gland was the greatest ((13.23 ± 13.39) ％ ∶ (3.20 ± 6.71) ％,P =0.002).In the secondary delineation after training,the Dmax of the optic chiasm in the junior and senior physicians was (1.68 ± 3.34)％ and (1.50 ± 1.87) ％,respectively (P =0.841),and the difference in junior physicians was reduced significantly compared with before training ((1.68 ± 3.34) ％ ∶ (5.85 ± 19.63) ％,P =0.048) ; the Dmean of the parotid gland in the junior and senior physicians was (2.46 ± 3.06) ％ and (1.35 ± 3.00) ％,respectively (P =0.2 7 4),significantly reduced compared with before training ((2.46 ± 3.0 6) ％ ∶ (13.23 ± 13.39)％,P=0.002; (1.35 ± 3.00)％ ∶ (3.20 ± 6.71) ％,P =0.033).Conclusions The differences in delineation of OAR lead to dose uncertainties during IMRT for NPC,and specific training can improve the accuracy of delineation.

Objective:To investigate and analyze the current status of multimodality therapy for resectable gastric cancer, aiming to provide reference for optimizing the multimodality treatment strategy for gastric cancer.Methods:Clinical data of patients diagnosed with gastric adenocarcinoma undergoing radical gastrectomy in the Second Affiliated Hospital of Soochow University were retrospectively analyzed. Clinical characteristics, preoperative medical comorbidities, pathological features, surgical and perioperative status and clinical efficacy were recorded. The gap between the diagnosis and treatment procedures and the standard guidelines was analyzed. The changes in the multimodality treatment patterns for gastric cancer were understood.Results:A total of 265 patients were included in this study. All patients were divided into two cohorts: early[2008] and late[2013] cohorts. In the early cohort, 127 patients were assigned, and 138 cases in the late cohort. In the early cohort, 67 patients (52.8%) underwent D 2 lymph node dissection, significantly less than 83 patients (60.1%) in the late cohort ( P<0.01). In the early and late cohorts, the proportion of patients with the number of lymph node dissection of ≥15 was 5.5% and 52.8%( P<0.01). The median number of lymph node dissection was increased from 6 to 16. The proportion of patients receiving neoadjuvant chemotherapy in the early and late cohorts was 2.4% and 3.6%( P=0.55). In the early cohort, the proportion of patients treated with postoperative chemotherapy and postoperative adjuvant chemoradiotherapy was 62.6% and 2.4%, significantly higher compared with 58.0% and 8.0% in the late cohort ( P=0.04). In addition, the proportion of patients receiving postoperative chemotherapy in the early cohort was 62.2%( n=79) and 58.0%( n=80) in the late cohort ( P=0.48). Conclusions:Although the level of radical gastrectomy has been continuously improved and standardized in China, which still lags behind the standard D 2 radical gastrectomy in Japan and South Korea. Adjuvant therapies including postoperative adjuvant radiotherapy can bring clinical benefits. However, the proportion of patients receiving adjuvant therapy is still low, and the multimodality therapy of gastric cancer should be widely applied.

Objective To evaluate the efficacy and safety in the treatment of acetabular fractures via anterior approaches,including ilioinguinal,stoppa,pararectus approach.Methods Systematic literature retrieval was carried out to obtain two-arm and one-arm researches on the treatment of acetabular fractures via any one of the three approaches before May 2017,from pubmed,embase,cochrane library Databases.Data extraction and quality evaluation of studies were performed by 3 investigators independently.A meta-analysis was performed by RevMan 5.3 and Meta-Analyst beta 3.13.Results Totally 22 low to moderate quality studies,including 7 two-arm and 15 one-arm were included.There were 980 patients,including 581 in ilioinguinal approach group,264 in stoppa approach group and 135 in pararectus approach group.Meta-analysis showed the rate of anatomic reduction in stoppa approach was higher than that in ilioinguinal approach (OR=0.58,95％CI:0.36-0.94,P=0.03),which in pararectus approach was higher than that in ilioinguinal approach (0R=2.95,95％CI:1.22-7.10,P=0.02).Compared to the ilioinguinal approach,the operation time in the Stoppa approach was shorter (MD=48.01,95％CI:17.08-78.95,P=0.002),there was no statistically significant difference between pararectus approach and ilioinguinal approach.In addition,there were no statistically significant differences among three approaches in intra-operative blood loss,postoperative functional outcomes and complications.Conclusion The available limited evidence suggests that the rate of anatomical reduction in stoppa and pararectus approach may be higher than ilioinguinal approach.Compared to the ilioinguinal approach,the operation time in the stoppa approach may be shorter.In this field,further rigorous design,baseline parallel,direct comparison controlled studies on this topic are still needed.

Objective To analyze the effect of the changes of hospital diagnosis and treatment mode on the treatment time in patients with acute ischemic stroke before and after the establishment of Cerebrovascular Disease Center. Methods A total of 103 consecutive patients with acute ischemic stroke admitted to the Department of Neurology,Changhai Hospital,the Second Military Medical University between June 2008 and December 2012 were enrolled retrospectively. Thirty-one of them were excluded because of incomplete medical records. Finally,72 patients were enrolled as a control group and received series diagnosis and treatment mode. A total of 210 consecutive patients with acute ischemic stroke admitted to the Cerebrovascular Disease Center,Changhai Hospital,the Second Military Medical University from September 2013 to February 2015 were enrolled retrospectively. Thirteen patients were excluded (4 patients with recurrent transient ischemic attack were treated with recombinant tissue-type plasminogen activator,9 without complete data were treated with intravenous thrombolysis),197 were enrolled as an observation group finally,and they were received series diagnosis and treatment mode. The patients of both groups were visited within 4. 5 h after onset and received rt-PA treatment. The time-consuming changes of each time period from onset-to-door,door-to-imaging,imaging-to-needle,door-to-needle,and onset-to-needle time between the control group and the observation group were compared and analyzed. Results Compared with the control group,the door-to-imaging,imaging-to-needle,door-to-needle and onset-to-needle time were significantly shorter in the observation group. There were significant difference between the 2 groups (24 ± 12 min vs. 60 ± 20 min,27 ± 12 min vs. 62 ± 31 min,51 ± 17 min vs. 122 ± 52 min,and 153 ± 69 min vs. 230 ± 81 min,all P < 0. 01). There was no significant difference for onset-to-door time between the observation group and the control group (P > 0. 05). Conclusion The establishment of cerebral vascular disease center and the improvement of the processes have shortened the treatment time in patients with acute ischemic stroke within time window. The time from onset-to-door is still longer,and the propaganda and education of stroke should be strengthened.

ObjectiveTo observe the effect of the nine points for hemiplegia plus MOTOmed exercise training system on the lower-extremity function of the patients with post-stroke hemiplegia.MethodForty-five patients with post-stroke hemiplegia were randomized into 3 groups, 15 each.Group A was intervened by regular acupuncture treatment, group B was by the MOTOmed training system, and group C was by the nine points for hemiplegia during the exercise training by the MOTOmed system in addition to the regular acupuncture treatment. The National Institute of Health Stroke Scale (NIHSS) and Fugl-Meyer (FMA) scale were adopted for evaluation and comparison before intervention and after 4-week intervention.ResultBefore intervention, there were no significant differences in comparing the function of lower extremity among the three groups (P>0.05);after 4-week intervention, the observation indexes were improved in the three groups, and the improvement in group C was the most significant (P<0.05), and it was significantly different from that of group A and B at the corresponding time point (P<0.05). ConclusionThe nine points for hemiplegia plus MOTOmed exercise training can effectively improve the lower-extremity function in the patients with post-stroke hemiplegia.

Objective To compare the treatment effect between Duply combined with Duckett and Koyanagi surgical methods in severe hypospadias.Methods Forty-two cases of severe hypospadias were divided into two groups according to the surgical method,23 cases was enrolled in Duply combined with Duckett group while 19 cases in Koyanagi group.The operation time,the incidence rate of urinary fistula,urethral stricture,urethral diverticulum and penis torsion were compared.Results The operation time between two groups had no significant difference (P ＞ 0.05).The incidence rate of urinary fistula,urethral stricture,urethral diverticulum and penis torsion between two groups had no significant difference (x2 =0.04,0.31,0.03,1.16,P ＞ 0.05).The total incidence rate of complications between Duply combined with Duckett group and Koyanagi group had significant difference [69.6％ (16/23) vs.6/19] (x2 =4.59,P ＜ 0.05).Conclusion Each of the two methods can be a choice in treatment of severe hypospadias.

Objective To analyze the effects of quality supervision and continuous improvement system on optimizing in-hospital diagnosis and treatment process in patients with acute ischemic stroke (AIS).Methods From September 2013 to May 2016,424 consecutive patients with AIS treated with intravenous thrombolysis and/or endovascular therapy in Changhai Hospital,the Second Military Medical University were enrolled retrospectively.They were analyzed according to the annual running process (the first year[from September 2013 to August 2014],the second year[from September 2014 to August 2015],and the third year[from September 2015 to May 2016]).The spend time and delay (DTN>60 min,DTP>90 min) rate of each treatment process in the first,second,and third year (time from door-to-imaging[DTI],door-to-needle[DTN],imaging-to-needle (ITN),door-to-groin puncture (DTP) and imaging-to-groin puncture (ITP) were compared.Taking the time periods (>median) of having significant differences of the spend time of the treatment processes as the dependent variables in the first,second,and third year,the influence of the years and treatment modalities on delay was observed.The difference of constituent ratio of the reasons for delay in intravenous thrombolysis and endovascular therapy (objective reasons/other reasons) in different years were analyzed.Results (1) DTIs were 23.0 (11.0,42.0) min,22.0 (10.1,39.0) min,and 13.0 (6.0,27.0) min,respectively,and DTNs were 50.0 (30.0,77.1) min,45.0 (30.0,70.2) min,and 36.0 (24.0,57.0) min,respectively in the first,second,and third year.The spending time was shortened year by year.There were significant differences among the different years (all P<0.01).The spending time of DTP had a tendency to be shortened,but there were significant differences among different years (P=0.06).There were no significant differences between the spending time of ITN and ITP (all P>0.05).(2) The DTN delay rates were 33.3% (40/120),20.7% (29/140),and 8.1% (9/111),respectively in the first,second,and third year.There were significant differences among the 3 years (x2=22.111,P<0.01).There were no significant differences among the DTP delay rates (P=0.08).(3) Multivariate Logistic regression analysis showed that taking the first years as a reference,the risk of DTI delay was reduced in the third year (OR,0.174,95%CI 0.101-0.298,P<0.01),the risks of DTN delay were reduced in the second and third year (OR,0.564,95%CI 0.338-0.941;OR,0.180,95%CI 0.101-0.320,all P<0.05).For simple intravenous thrombolysis,bridging therapy was a protective factor for the improvement of treatment efficiency in the DTI process (OR,0.530,95%CI 0.297-0.943,P=0.031).Compared with the bridging therapy,the direct endovascular therapy was a protective factor for DTP treatment (OR,0.427,95%CI 0.202-0.901,P=0.025).The remaining independent variables were not associated with the occurrence of DTN and DTP delay (all P>0.05).(4) During the three years,the delay of intravenous thrombolysis was mainly due to objective reasons.The constituent ratio of other reasons caused delay of intravenous thrombolysis was decreased year by year.There was no other reasons for delay in the third year).There was no significant difference in the constituent ratio of the delay reasons in endovascular treatment (x2=3.622,P=0.164).Conclusion Under the existing process and resource allocation,setting the DTN target time and implementing continuous quality improvement are conducive to the effective implementation of brain CT scan and continuous optimization of intravenous thrombolysis in the processes in AIS patients with the first diagnosis.
