Objective To determine the clinical characteristics and its effect on the clinical efficacy of residual bony impingement lesion after hip arthroscopic osteoplasty for pincer-type femoroacetabular impingement.Methods There were 30 patients who underwent hip arthroscopic osteoplasty for isolated pincer-type femoroacetabular impingement from December 2010 to January 2012 and had a minimum follow-up period of 2 years,including 21 males and 9 females.The average age at surgery was 34.5 years (range from 28-42 years).All of the patients had no advanced hip arthritis and the T(o)nnis grade was 0-2.Radiological evaluation was performed by 3-dimensional CT.According to residual rate,these patients were divided into 3 groups:residual rate ＜10％ group,residual rate of 10％-20％ groups and residual rate ＞20％ group.Results The average follow-up period was 26.3 months (range,22-34 months) and nineteen cases had residual bony impingement lesion after surgery.Among them,84.2％ of the residual bony impingement lesion was posterior to the acetabular actual resection zone.The preoperative and postoperative bony impingement angle were 77.47°±21.31° and 12.94°±18.04°,respectively.The residual rate was 16.7％± 8.83％.The modified Harris hip score got significantly improved from 55.18±7.96 preoperatively to 94.71±4.39 postoperatively.The overall satisfactory rate was 76.7％,and the postoperative modified Harris hip score for these three groups was 95.86±1.71,95.23±1.99 and 85.52±6.41,respectively.The postoperative modified Harris hip score in residual rate ＞20％ group was significantly worse than those in other two groups.The satisfactory rate was 92.9％,80.0％ and 33.3％,respectively.The satisfactory rate in residual rate ＞20％ group was significantly worse than those in other two groups.There was a significant negative linear relationship between the residual rate and postoperative modified Harris hip score (R2=0.516,P=0.001).Conclusion The incidence of residual bony impingement lesion after hip arthroscopic osteoplasty for pincer-type femoroacetabular impingement was 63.3％.The residual rate was 16.7％.The residual impingement lesion was mainly at the posterior part of the acetabulum.The patients with residual rate ＞20％ got significantly worse clinical score and satisfactory rate.

Objective To probe into the social support, coping styles, and mental health status of medical staff in a tertiary hospital in Beijing, for identifying potential mental problems. Methods Such means as the Social Support Rating Sheet (SSRS), Simple Coping Style Questionnaire (SCSQ), Symptom Checklist (SCL-90), and demographic characteristics questionnaire were called into play, to study 2460 medical staff in five tertiary hospitals in Beijing. Results Differences were identified among medical staff of different demographic characteristics, in terms of positive coping style and support dimensions. Analysis of the survey data indicates that the total SCL scores, total symptom problem index, positive symptom pain level, total average score of the factors, are positively related to passive coping style, as P<0. 01; and are negatively related to subjective/objective support, support utilization, and total support scores, as P<0. 01. Conclusions Hospital administration is expected to implement focused intervention to such medical staff as those under 40 years old, women, widows or divorcees, those with education lower than university degree, those with junior academic title or lower, those without titles, those in emergency departments and emergency intensive care units, doctors and nurses, frequent night-shift workers, those of excessively low self evaluation, and medical staff with chronic diseases. The purpose of this practice is to alleviate their mental stress.

Objective To study the impact of lymph node metastasis on prognosis of patients with pancreatic cancer and to evaluate predictors of postoperative survival of these patients.Methods The clinical data on patients with pancreatic cancer who underwent pancreatic cancer radical surgery in our hospital from January 2002 to December 2013 were reviewed and analyzed.Data on lymph node metastasis,number of lymph node dissection,number of positive lymph nodes and positive lymph ratio were analyzed.Results Of 101 patients,the 6-month,1-year and 2-year survival rates were 84.2％,56.6％ and 28.5％,respectively.The median survival was 13.8 months.Univariate and multivariate analyses showed lymph node metastasis,a positive lymph node ratio,number of lymph node dissection and positive lymph nodes were independent influential factors of prognosis.Results of subgroup analysis showed the number of lymph node dissection was a prognostic factor for pNO patients,while a positive lymph ratio had no impact on survival of pN1 patients.In the subgroup of patients with pancreatic head cancer,lymph node metastasis was associated with prognosis but not in the subgroup of patients with pancreatic body and tail carcinoma.Conclusions For patients with pancreatic head cancer,lymph node metastasis was closely correlated with prognosis.In addition,factors including lymph node metastasis,number of lymph node dissection,a positive lymph node ratio and number of positive lymph nodes were independent influential factors of prognosis for patients with pancreatic head cancer.However,for pN1 patients,a positive lymph node ratio has no influence on prognosis.

Atropa belladonna is a medicinal plant and main commercial source of tropane alkaloids (TAs) including scopolamine and hyoscyamine, which are anticholine drugs widely used clinically. Based on the high throughput transcriptome sequencing results, the digital expression patterns of UniGenes representing 9 structural genes (ODC, ADC, AIH, CPA, SPDS, PMT, CYP80F1, H6H, TRII) involved in TAs biosynthesis were constructed, and simultaneously expression analysis of 4 released genes in NCBI (PMT, CYP80F1, H6H, TRII) for verification was performed using qPCR, as well as the TAs contents detection in 8 different tissues. Digital expression patterns results suggested that the 4 genes including ODC, ADC, AIH and CPA involved in the upstream pathway of TAs, and the 2 branch pathway genes including SPDS and TRII were found to be expressed in all the detected tissues with high expression level in secondary root. While the 3 TAs-pathway-specific genes including PMT, CYP80F1, H6H were only expressed in secondary roots and primary roots, mainly in secondary roots. The qPCR detection results of PMT, CYP80F1 and H6H were consistent with the digital expression patterns, but their expression levels in primary root were too low to be detected. The highest content of hyoscyamine was found in tender stems (3.364 mg x g(-1)), followed by tender leaves (1.526 mg x g(-1)), roots (1.598 mg x g(-1)), young fruits (1.271 mg x g(-1)) and fruit sepals (1.413 mg x g(-1)). The highest content of scopolamine was detected in fruit sepals (1.003 mg x g(-1)), then followed by tender stems (0.600 mg x g(-1)) and tender leaves (0.601 mg x g(-1)). Both old stems and old leaves had the lowest content of hyoscyamine and scopolamine. The gene expression profile and TAs accumulation indicated that TAs in Atropa belladonna were mainly biosynthesized in secondary root, and then transported and deposited in tender aerial parts. Screening Atropa belladonna secondary root transcriptome database will facilitate unveiling the unknown enzymatic reactions and the mechanisms of transcriptional control.

This study is to investigate the effect of baicalin (BL) against oxidative injury stress of SH-SY5Y cells induced by H2O2 and the possible mechanism. SH-SY5Y cells were pre-incubated with baicalin (25, 50, and 100 micromol x L(-1)) for 12 h prior to exposure to H2O2 (150 micromol x L(-1)) for 24 h. The viability of SH-SY5Y cells was measured by MTT assay. The contents of LDH and NO were determined. The percentage of apoptotic cells was assessed by flow cytometry (FCM). The content of Caspase-3 was tested by immunofluorescence histochemical method. BL at 50 and 100 micromol x L(-1) separately increased the cell viability and up-regulated SIRT1, reduced the contents of LDH, NO, Caspase-3 and the apoptotic percentage of SH-SY5Y cells. This study results suggest that baicalin could inhibit the H2O2-induced neuronal apoptosis. The further mechanism studies show that baicalin inhibit apoptosis via reducing Caspase-3 expression and up-regulating SIRT1.

Objective The present study was to differentiate the hyperdensities on CT immediately after intra-arterial thrombolysis in patients with acute isehemic stroke.Methods Twenty two patients with acute ischemic stroke were treated with intra-arterial combining with intravenous thrombolysis within 6 hours after onset.All patients underwent nonenhaneed CT scans before,immediately and 24 hours after thrombolytic therapy.The hyperdensities on CT after intra-arterial thrombolysis were analyzed retrospectively.Results Five hyperdense areas were seen in 22 patients immediately after thrombolytie therapy.According to their locations, CT values and follow-up CT scans,the hyperdensities on CT imaging were classified into two groups:contrast enhancement and hemorrhagic transformation.The former was characterized by rapid clearance of the hyperdensity lesion with maximum Hounsifild Unit＜90,on the contrary,the latter was noted by persistence of hyperdensity lesion after 24 hours CT scan with maximum Hounsifild Unit＞90.Two of the five hyperdense lesion patients were confirmed to be contrast enhancement with location in cerebral cortex,the other were hemorrhagic transformation,mostly located in basal ganglia.Hyperdensity in patients with contrast enhancement showed neurological improvement although no further medical cares were offered.Conclusions Different kind of hyperdensity on CT immediately after intra-arterial thrombolysis in patients with acute ischemic stroke can be differentiated according to its location,CT value and follow-up CT scan.When contrast enhancement occurred,no further medical care is needed.

The aim of this research was to understand the influence of rhG-CSF on the sphingosine kinase (SphK) activity of monocytes. The peripheral blood monocytes were collected from 6 peripheral blood progenitor cell donors on the fifth day of mobilization with rhG-CSF and from 5 blood donors' buffy coats. The mRNA expressions of monocyte G-CSF receptor and SphK were tested with RT-PCR. The changes of SphK activity of monocytes were assayed after being treated with rhG-CSF. The results showed that the two kinds monocytes collected from both blood donors and peripheral blood progenitor cell donors mobilized with rhG-CSF expressed mRNA of G-CSF receptor and SphK. The SphK activity of monocytes collected from blood donors was not changed significantly after being treated with rhG-CSF (P > 0.05). The SphK activity of monocytes collected from peripheral blood progenitor cell donors transiently increased by (39.6 - 87.2)% after being treated by means of rhG-CSF (P < 0.05) without obviously dose-dependent effect. It is concluded that the SphK activity of monocytes collected from peripheral blood progenitor cell donors can be activated by rhG-CSF.
