Objective To explore the clinical features of spontaneous spinal epidural hematoma (SSEH) and to find out factors influencing its prognosis. Methods From September 1998 to October 2006, 23 patients with SSEH (10 males and 13 females) were treated. Their ages ranged from 10 to 69 years. The primary neurological status were classified as grade A in 7 patients,B in 2 patients, C in 4 patients, D in 9 patients and E in 1 patients accordingto ASIA grading system. The progressive intervals of their symptoms were divided as four period: less than 12 hours (12 patients), 12 to 24 hours(2 patients), 24 to 48 hours(3 patients) and more than 48 hours(6 patients). SSEH was diagnosedby MRI or by histopathological examination. The cases history, laboratory examination, radiological image, treatment, pathological result and prognosis were recorded and analyzed after 3 month. Results In 23 patients, there were 1 case of deterioration, 8 cases of no change, 9cases of improvement and 5 cases of complete recovery. The gender had no correlationwith prognosis(P＞0.05). In the patients who had shorter progressive interval and more severe edema of spinal cord, the prognosis was worse(P＜0.05). Inthe patients who had mild neurological deficit, the prognosis was good (P＜0.01). In 17 patients undergoing surgery, the scores for prognosis was 1 point in 1 case, 2 points in 5 cases, 3 points in 6 cases and 4 points in 5 cases; the operation time had no correlation with prognosis(r=0.056, P＞0.05). In6patients undergoing conservative treatment, the scores for prognosis were 2 points and 3 points in 3 cases respectively. Conclusion Prognosis of patient with SSEH is influenced by his primary neurological status, progressive interval, spinal edema and size of hematoma. The major treatment is surgical evacuation of hematoma as early as possible to break the aggravation of spinal function. Conservative treatment is not considered unless the neurological defects recovered in the early period.
Objective To improve the awareness of acute exacerbation of idiopathic pulmonary fibrosis ( AEIPF) and discuss its clinical characteristics, diagnosis, treatment and outcome. Methods The clinical data of patients with AEIPF from June 2006 to June 2011 in 11 hospitals in Jiangsu were collected and analyzed. Resluts There were 18 males and 3 females in the AEIPF patients with mean age of ( 67.4 ± 8.1) years. The duration from IPF diagnosis was ( 7.4 ±8.2) months. The duration of acute symptom before admission was ( 7.0 ±5.3) days. The distribution pattern of new groud-glass opacity was peripheral in 3 patients,multifocal in 5 patients, and diffuse in13 patients. All patients were treated with corticosteroid pulse therapy. Nine patients survived and 12 patients died. The mortality rate was 57.1% . Conclusions AEIPF progresses quickly and the mortality rate is very high. Corticosteroid pulse therapy is the mainstay of therapy in AEIPF patients.
ObjectiveTo investigate the predicting effect of PIK3CA mutations for the efficacy and prognosis of hepatocellular carcinoma (HCC) patients received surgical resection. MethodsPCR and DNA sequencing were used to detect the PIK3CA mutation status of 79 HCC tissues, its impact on the short and long term effects of the patients were analyzed. ResultsIn this group of patients, mutation rate of PIK3CA gene exon 9 was 39.24% (31/79), PIK3CA mutation rate correlated with lymph node status and tumor differentiation (P < 0.05). The therapeutic effect of patients with PIK3CA mutation was significantly poor than that of the non-mutated group (P < 0.05). The three-year cumulative survival of patients with PIK3CA mutation (33.33%) was significantly lower than non-mutated group's (60.00%) by Kaplan-Meier (P < 0.05). ConclusionPIK3CA gene mutation in exon 9 could impact the efficiency of surgical resection in patients with HCC and could predict a poor survival prognosis.
Objective To explore the predictive factors for long-term adverse prognosis in patients with tuberculosis meningitis. Methods We retrospectively analyzed the clinical data (general clinical data, laboratory test results, and imaging findings) of hospitalized cases of tuberculosis meningitis admitted to West China Hospital of Sichuan University from 00:00:00 on August 1st, 2011 to 23:59:59 on July 31st, 2012. We collected data of prognosis results after 6 years of illness by telephone follow-up, and quantified outcome measures by modified Rankin Scale (mRS) score (0–6 points). According to the mRS score, the cases obtaining 0 points≤mRS<3 points were divided into the good prognosis group and the cases obtaining 3≤mRS≤6 points were divided into the poor prognosis group, logistic regression analysis was executed to find the independent risk factors affecting long-term poor prognosis. Results A total of 119 cases were included, including 63 males and 56 females; the average age was (35±17) years. Among them, 53 patients had poor prognosis and 66 patients had good prognosis. After univariate analysis, the age (t=–3.812, P<0.001), systolic blood pressure at admission (t=–2.009, P=0.049), Glasgow Coma Scale score (t=3.987, P<0.001), Medical Research Council (MRC) staging system (Z=–4.854, P<0.001), headache (χ2=4.101, P=0.043), alter consciousness (χ2=10.621, P=0.001), cognitive dysfunction (χ2=4.075, P=0.044), cranial nerve palsy (χ2=5.853, P=0.016), peripheral nerve dysfunction (χ2=14.925, P<0.001), meningeal irritation (χ2=7.174, P=0.007), serum potassium (t=3.080, P=0.003), cerebrospinal fluid protein content (Z=–2.568, P=0.010), cerebrospinal fluid chlorine (t=2.543, P=0.012), hydrocephalus (χ2=11.766, P=0.001), and cerebral infarction (χ2=6.539, P=0.012) were associated with long-term poor prognosis of tuberculosis meningitis. Multivariate analysis showed that age [odds ratio (OR)=1.061, 95% confidence interval (CI) (1.027, 1.096), P<0.001], peripheral nerve dysfunction [OR=3.537, 95%CI (1.070, 11.697), P=0.038], MRC Stage Ⅱ[OR=9.317, 95%CI (1.692, 51.303), P=0.010], MRC Stage Ⅲ [OR=43.953, 95%CI (3.996, 483.398), P=0.002] were the independent risk factors for long-term poor prognosis of tuberculosis meningitis. Hydrocephalus [OR=2.826, 95%CI (0.999, 8.200), P=0.050] might be an independent risk factor for long-term poor prognosis of tuberculosis meningitis. Conclusions Age, MRC staging system (Stage Ⅱ, Stage Ⅲ) and peripheral neurological dysfunction are chronic poor-prognostic independent risk factors for tuberculosis meningitis. Hydrocephalus may be associated with long-term adverse prognosis of tuberculosis meningitis
ObjectiveTo assess the value of simplified clinical pulmonary infection score (sCPIS) in predicting prognosis of patients with ventilator-associated pneumonia (VAP). MethodsThe clinical data of 52 patients with VAP,admitted in ICU between January 2011 and December 2012,were retrospectively analyzed. The sCPIS was calculated at the onset,and on 3rd,5th and 7th day after onset of VAP. Results24 cases survived and 28 cases died in 28-day's hospitalization. 28-day mortality was 53.8%. A significant decrease in sCPIS scores was found on 3rd,5th and 7th day after onset compared with at the onset of VAP in the survivors(4.8±1.2,4.0±1.1,3.3±1.6 vs. 5.5±1.4,P<0.05). An increase in sCPIS scores was found on 3rd,5th and 7th days after onset compared with at the onset of VAP in the non-survivors (6.8±1.3,7.5±1.4,7.8±1.2 vs. 5.8±1.5,P<0.05). The sCPIS determined at the time of VAP diagnosis and on 3rd,5th and 7th day after onset was significantly higher in the non-survivors than that in the survivors respectively (P<0.05). The duration of mechanical ventilation and the length of ICU stay were longer in the non-survivors than those in the survivors[(18.4±5.2) d vs. (12.0±4.1) d,(22.5±8.5) d vs. (16±6.3) d,P<0.05]. ConclusionSerial measurement of sCPIS is valuable in evaluating the severity of illness and predicting the prognosis.
Objective To study the factors affecting the prognosis of vitrectomy in mechanically injured eyes. Methods One hundred and thirty-Seven eyes undergone vitrectomy were in cluded.Recorded to EPIINFO data base were visual acuity (VA) immediately after injury,type and location of injury,the interval from injury to surgical intervention,retinal detachment,basic surgical maneuvers,proliferative vitreo-retinopathy (PVR),stage of trauma,complications,final VA,and final retinal status.Data were analyzed by SAS. Results We got anatomic success in 107 eyes (75.9%).Final VA of 74 eyes (54.1%) were better than 0.02.Multiple-variable analysis showed that the factors significantly affecting prognosis of vitrectomied eyes of mechanical injury were retinal detachment (RD) before surgery,delay of surgical intervention,complexity of surgical maneuvers,complications after surgery. Conclusions RD before surgery,delayed surgical intervention,complexity of surgery and post vitrectomy complications are the most important factors contributing to the poor prognosis of VA and failure of surgery.

We have used immunphistochemical SP method to detect the expression of nm23 gene protein in human thyroid tissues from 86 carcinomas, 20 adenomas and 25 carcinomatous adjecent tissues. The results showed the positive staining rate were 73.3%, 40.0%and 16. 0% respective (Plt; 0. 005). Although the expression of nm23 protein had no association with the cervical lymph node metas-tases,it was significantly concordant with the tumor cell diffierentiation (Plt;0. 01) ,tumer capsule (Plt; 0. 05) and TNM stage (Plt;0.05).In addition, the patient‘s average survival time in nm23-positive cases was longer than that in nm23-negative ones (Plt;0.01).This data suggest that nm23 gene may play an important role in thyroid carcinogenesis and the expression of nm23 protein would be an useful marker in assessing the prognosis of the thyroid carcinomas.
ObjectiveTo investigate the expressions and significance of chemokines factor receptors 4 (CXCR4) and chemokines factor receptors 7 (CXCR7) in gastric cancer tissues. MethodsSixty-five patients with gastric cancer who treated in our hospital from January 2011 to June 2013 were retrospectively collected as gastric cancer group, and 20 patients with gastric ulcer were retrospectively collected as control group at the same time. The expressions of CXCR4 and CXCR7 in gastric cancer tissues and normal gastric tissues were measured by immunohistochemistry, and then the relation-ship among expressions of CXCR4/CXCR7 in gastric cancer tissues and clinicopathological features of patients with gastric cancer was explored, as well as its effect on survival. ResultsPositive expression rates of CXCR4 and CXCR7 were identi-fied in 80.00% (52/65) and 84.62% (55/65) of the gastric cancer group, and 5.00% (1/20) and 10.00% (2/20) in control group respectively, and the positive expression rates of CXCR4 and CXCR7 in gastric cancer group were significantly higher than those of control group respectively (χ2=36.65, P<0.01; χ2=38.55, P<0.01). The positive expression rate of CXCR4 in gastric cancer tissues was related with degree of differentiation, T staging, and TNM staging (P<0.05), positive expression rate of CXCR4 in patients with poor differentiation, T3-4 staging, and TNM Ⅲ-Ⅳ staging were higher than corresponding patients with moderate/high degree of differentiation, T1-2 staging, and TNM Ⅰ-Ⅱ staging. The positive expression rate of CXCR7 in gastric cancer tissues was related with degree of differentiation, T staging, and N staging (P<0.05), positive expression rate of CXCR7 in patients with poor differentiation, T3-4 staging, and N1-3 staging were higher than corrsponding patients with moderate/high degree of differentiation, T1-2 staging, and N0 staging. The survival situation was worse in patients with positive expression of CXCR4 and CXCR7 than corresponding patients with negative expression (P=0.01, P=0.01) respectively. ConclusionsCXCR4 and CXCR7 are related to gastric cancer genesis and development. Furthermore, the expressions of CXCR4 and CXCR7 could be used as markers to predict prognosis of gastric cancer. The regulation of CXCR4/chemokine ligand 12 (CXCL12) axis and CXCR7/CXCL12 axis may provide a new targeted therapy for patients with gastric cancer.
Objective To explore the clinical significance of internal mammary nodes in diagnosis and treatment of breast cancer. Methods The research papers on internal mammary nodes at home and abroad were analyzed in order to summarize the distribution, metastasis, detection and the effects of clinical treatment of the internal mammary nodes in breast cancer. Results The internal mammary nodes mainly locate near the sternum, along with the internal mammary artery and vein in the thorax. They were prone to metastasize at early stage and the metastasis rate also increased with the increased number of axillary lymph nodes in breast cancer. It could influence the recovery of the breast cancer patients by taking biopsy and treatment to the internal mammary nodes. Conclusion The biopsy and treatment of internal mammary nodes are useful for the patients with breast cancer to avoid the recurrence and helpful to stage, treatment and prognosis judgement of the breast cancer patients.
Objective Heparan sulfate proteoglycans (HSPGs) is an important component of the extracellular matrix. syndecan-1, a member of syndecan family, belongs to HSPGs and plays an important role in cell morphology and intracellular arrangement. The present study was designed to investigate the expression of syndecan-1 in patients with colorectal cancer, to analyse its relationship to cancer progression and clinical prognosis. Methods Paraffin-embeded specimens were collected from 31 patients with colorectal cancers from 2003 to 2004 in Peking Union Medical College Hospital. Syndecan-1 protein expression was measured by immunohistochemistry. Its expression was evaluated with relationship to clinicopathological factors, including tumor infiltration, tumor differentiation, lymph node metastasis, accompanying with colorectal adenoma and 2-year survivals. Results Immunohistochemistry in 31 specimens showed syndecan-1 were detected positive in 1 colorectal cancer tissue (3.2%), while positive in 29 normal tissues (93.5%), with significant difference (P＜0.01). No prognostic differences could be found in the clinic outcome because of the high expression rate of syndecan-1 in normal tissues and low expression rate in cancer tissues. Conclusion Syncecan-1 is expressed in normal colorectal tissues and rarely expressed in cancer tissues.
