OBJECTIVETo compare clinical outcomes of locking plate for proximal humeral fracture whether application of inferomedial screws.

METHODSFrom January 2012 to July 2013, 46 patients with proximal humeral fracture underwent locking plates were retrospectively analyzed. There were 25 males and 21 females aged from 29 to 80 years old with an average of 55.1 years old. Among them, 25 patients were treated with inferomedial screws (support group), including 13 males and 12 females aged from 38 to 80 years old with an average of (55.8 ± 11.8) years old; 8 cases were part two fracture,10 cases were part three fracture and 7 cases were part four fracture according to Neer classification. Twenty-one patients were treated without inferomedial screws (non-support group), including 12 males and 9 females aged from 29 to 79 years old with an average of (54.2 ± 14.8)years old; 6 cases were part two fracture, 9 cases were part three fracture and 6 cases were part four fracture according to Neer classification. Operative time, fracture healing time and complications were observed and compared, Neer scoring of shoulder joint were used to evaluate clinical effect.

RESULTSAll patients were followed up from 12 to 41 months with an average of 15.6 months. Operative time and fracture healing time in support group was (1.6 ± 0.4) h and (3.0 ± 0.6) months, and (1.5 ± 0.4) h and (3.1 ± 0.6) months in non-support group, while there was no statistical difference in operative time and fracture healing time between two groups. There was significant differences in Neer score between support group (89.7± 4.9) and non-support group (83.1 ± 7.1). No complication occurred in support group,while 4 cases occurred complications in non-support group.

CONCLUSIONLocking plate with inferomedial screws for proximal humeral fracture has advantages of stable fixation, less complications, quick recovery of function and satisfied clinical effect.

Background Pterygium is a common ocular surface disease and its treatment is surgical excision.But recurrence rate of pterygium is high after operation.Recently,some studies showed that the postoperatively topical administration of cyclosporine A (CsA) reduce the recurrence of pterygium,but this conclusion needs basis of evidence-based medicine.Objective This systematic review was to investigate the efficacy and safety of postoperatively topical usage of CsA in preventing the recurrence of primary pterygium.Methods A systematic literature retrieval was conducted and the relative articals were searched from MEDLINE,EMBASE,Cochrane Library,CNKI,Wanfang and VIP databases up to October 2012 according to searching strategy and correlated words.Randomized controlled trial (RCT) and prospective Cohort studies data were extracted by two researchers separately.The outcome parameters,such as the rate of recurrence,Schirmer Ⅰ test (S Ⅰ t) and complications were analyzed.The statistical analysis of the relative risk (RR) or weighted mean difference (WMD) was performed using a RevMan 5.0 software.Fixed-effect model was used for the inhomogeneity multiple studies (P≥0.1,homogeneity test I2 ＜ 50％),and random-effect model was used for the homogeneity study.Results Six prospective studies involving 366 eyes of 309 participants were identified,including 4 RCT and 2 non-RCT.The literature was published in 2008-2012 with the Jadad 5 scores in 1 paper and 2 scores in 3 papers for RCT and 6-7NOS (The Newcastle-Ottawa Scale) scores in 2 papers for Cohort studies.Meta-analysis showed that the recurrence and complication rates were significantly lower in the CsA group than those of the control group (RR =0.39,95 ％ CI:0.24-0.64,P =0.0002 and RR =0.24,95％ CI:0.13-0.44,P ＜ 0.00001) respectively.The postoperatively increased value of S Ⅰ t in the CsA group was significantly higher than that of the control group (WMD =2.47,95％CI:1.59-3.35,P ＜ 0.00001).Subgroups analyses suggested that the results were comparatively reliable.Conclusions Postoperative application of CsA can be effective for preventing recurrences and reducing complications after primary pterygium surgery.

Objective To investigate the injury characteristics and prognostic risk factors of patients with craniocerebral injury so as to provide some suggestions for the improvement of medical prevention,intervention and treatment measures.Methods Trauma database system was applied to collect the medical records of 661 patients with traumatic brain injury admitted to the Department of Neurosurgery of 105th Hospital of Hefei in 2009.Their general conditions,injury characteristics and outcomes were analyzed and the risk factors affecting their outcomes were investigated by Logistic regression analysis.Results Of the patients with craniocerebral injury,the males accounted for 70％ (463/661).The patients at 45 years old or so had the highest incidence of craniocerebral injury.Patient number in the second half of one year was 1.65 times more than that in the first half of one year (412/249 ).Most patients were injured from traffic accidents (87.7％,580/661 ) and 512 patients (77.5％) suffered from multiple injuries.ISS,injury causes,age and injury incidence quarters showed close correlation with the final outcome.Conclusions The patients with craniocerebral injury demonstrates distinctive characteristics in aspects of gender,age,incidence time,injury causes,and multiple injuries,but the ultimate outcomes are related to the injury severity,injury causes,age and other factors.

Objective To evaluate the clinical value of pulmonary embolism severity index (PESI) in non high-risk acute pulmonary thromboembolism (APTE) patients treated with sequential anticoagulation.Methods Non high-risk APTE patients treated with sequential anticoagulation were divided into two groups according to PESI:high-value group and low-value group.Prognosis and treatment response was compared between two groups.Results There were 82 cases in high-value group,and 76 cases in low-value group.The rate of adverse events in high-value group was significantly higher than that in low-value group [23.2％(19/82) vs.7.9％ (6/76)] (x2 =5.0698,P =0.009),and 30 days cumulative hazard was also significantly higher than that in low-value group (P ＜ 0.05).The sensitivity of predicting adverse events by PESI was 76.0％,specificity was 52.6％,positive predicting value was 64.6％,and negative predicting value was 65.9％.The mortality in high-value group was significantly higher than that in low-value group [9.8％(8/82) vs.1.3％ (1/76)] (P =0.022).After 30 days of anticoagulation,the pulmonary artery systolic pressure,internal diameter of right ventricle in high-value group was significantly higher than that in low-value group [(39.4 ± 8.1) mm Hg (1 mm Hg =0.133 kPa) vs.(27.2 ± 5.5) mm Hg,(33.0 ± 7.8) mm vs.(21.7 ± 4.6) mm] (P =0.034,0.021),and arterial oxygen partial pressure was significantly lower than that in low-value group[(75.15 ± 12.41) mm Hg vs.(86.36 ± 9.22) mm Hg](P=0.016).Conclusions PESI can effectively predict short-term prognosis of non high-risk APTE patients treated with sequential anticoagulation.At least some of these patients might need treatment other than sequential anticoagulation.

Objective To evaluate the effects and security of PFNA and DHS in the treatment of unstable intertrochanteric fractures through meta analysis .Methods The randomized controlled trials(RCT) for comparing PFNA and DHS in the treatment of unstable intertrochanteric fracture were retrieved from MEDLINE ,EMbase ,Pubmed ,Cochrane library ,CBM ,CNKI ,VIP data‐bases by computer .The related orthopedic relevant documents and conference papers were collected by manual retrieval .The Rev‐Man5 .1 statistical software was used for conducting the meta analysis .Results Nineteen RCT were included ,involving 1 690 pa‐tients ,in which 871 cases were treated by using PFNA and 819 cases were treated by using DHS .Compared with DHS ,PFNA had the advantages of little trauma ,less blood loss ,short operation time ,short fracture healing time and postoperative bed time ,good hip function and low incidence of postoperative coxa vara and screw cutting ,but there were no statistical differences in the aspects of length of hospital stay ,fatality rate ,and incidences of fracture nonunion ,breakage of internal fixation ,femoral head necrosis ,short‐ening of the femoral neck ,femoral shaft fractures ,deep vein thrombosis ,urinary tract infection and other complications between the two groups(P>0 .05) .Conclusion The retrieved literatures show that PFNA internal fixation is superior to DHS internal fixation in treatment of unstable intertrochanteric fractures .

Objective To summarize and evaluate the clinical feature and misdiagnosis of pulmonary granulomatosis with polyangitis (GPA).Methods The clinical data of 47 patients of pulmonary GPA were analyzed retrospectively.The clinical feature and misdiagnosis were summarized.Results These patients were most commonly misdiagnosed as pulmonary infectious disease (61.8％,34/55) and pulmonary malignancy (27.3％,15/55) was the next in line.70.2％(33/47) patients had nose and sinus involvement,40.4％(19/47) patients had kidney involvement,25.5％ (12/47) patients had rash,19.1％(9/47) patients had eyes involvement,6.4％ (3/47) patients had peripheral neuritis,6.4％ (3/47) patients had gastrointestinal bleeding,4.3％(2/47) patients had pericardial effusion,87.2％(41/47) patients had positive for antineutrophil cytoplasmic(cANCA),76.6％(36/47) patients had positive for proteinase-3.Conclusions Almost all pulmonary GPA patients have extra-pulmonary multi-systemic involvement.They are often misdiagnosed as pulmonary infectious diseases and malignancy.Educating doctors on GPA constantly and screening possible patients with cANCA testing may help reduce the misdiagnosis.

Objective To explore the two-dimensional images features and color flow characteristics of scrofula, as well as their application in the localization of scrofula. Methods A total of 110 cases of the scrofula confirmed by operation were retrospectively analyzed. Two-dimensional images and color flow characteristics, the relationship with vascular traveling and the invasion site were recorded. Results Lymph nodes of the lateral neck region along with large vessels were most commonly involved, then followed the submaxillary lymph nodes and the lymph nodes anterior neck longitudinally. There might be multiple lesions behaving differently on two-dimensional images and with different color flow characteristics. Conclusion Most of scrofula can be diagnosed clearly according to the two-dimensional images and color flow characteristics. The description of relationship between involved lymph nodes with vascular, the depth and position of scrofula make the operation safety.

Objective To analyze the clinical and pathological characteristics of children with lupus nephritis(LN).Methods The data of 116 inpatients from Mar.2000 to Nov.2008 with LN were retrospectively analyzed.The clinical,immunochemical and pathological data were recorded.Renal tissue was observed by light microscopy and electron microscopy after HE,PAS,Masson and PASM staining according to WHO standards.Follow-up results showed complete remission,partial remission,disease activity,renal insufficiency and death.Results Of the 116 cases of LN,there were 27 male and 89 female with a ratio of male to female 1.03.3,and the mean age was(12.0?2.2) years.The incidence of nephrotic syndrome was 63.8 %(74 cases),and acute nephritis was 21.5%(25 cases).Class Ⅳ LN was the most frequent type(14 cases,50%) and classⅢ was next(25 cases,21.5%).In view of the outcome,rapidly progressive glomerulonephritis and class Ⅳ LN were the worst.LN was initially controlled in 96.5% of the patients.Relapses of LN were most caused by the intermittent treatment.Totally 32 cases showed different renal injury,and 6 cases progressed to death.Conclusions Renal biopsy is important to diagnosis,treatment and prognosis evaluation of LN.Long and regular treatment is important for children with LN.
