Objectives Retrospective analysis of the Tibetan convulsive status epilepticus (CSE) for the aetiology, prognosis and its influencing factors in Tibet area. Methods Through electronic patient record, making “epilepsy”, “status epilepticus ”, “epileptic seizure” as keywords, convulsive status epilepticus patients in the People’s Hospital of Tibet Autonomous Region hospitalized from January 2015 to December 2020 were retrospectively observed, gathering their clinical data and aided examinations furthermore, and the prognoses were returned by telephone, meanwhile the functional status of those patients was assessed by the modified rankin scale. and the causes differ in gender, age, out-of-hospital antiepileptic treatment, family history of epilepsy and history of epilepsy were analyzed. The prognostic factors were analyzed by logistic regression. Results A total of 2 254 hospitalized patients with epilepsy were retrieved, including 331 CSE patients aged 14~84 years, 219 males and 112 females. There were 36 lost calls, 62 CSE deaths (21.01%), and 4 adverse outcomes (non-death)(1.7%).There were statistically significant differences in etiology of CSE in different ages and history of epilepsy (P<0.05), but there were no statistically significant differences in gender, out-of-hospital antiepileptic treatment, progression of refractory status epilepticus and family history of epilepsy. Cerebrovascular disease was the main cause of CSE in people aged 45 and over (54 cases), while the main cause of CSE in people aged under 45 was unknown (104 cases).Among the patients with previous history of epilepsy, the highest proportion was unknown cause [117 cases (48.8%)]; Among patients without a history of epilepsy, cerebrovascular disease [34 cases (37.4)] was the most common cause of CSE. Multivariate logistic regression analysis of prognostic factors of CSE showed that gender, age, GCS and electrolyte disorder had statistically significant effects on the death of CSE patients (P<0.05), while altitude and their duration and other factors had no statistically significant effects on the death of CSE patients (P>0.05). ConclusionsCerebrovascular disease is the leading cause of CSE in people aged 45 and over. Male, advanced age, low GCS score at discharge, and electrolyte disorder were risk factors.
Objectives To investigate the correlation between blood total cholesterol (TC) and prognosis of idiopathic sudden sensorineural hearing loss (ISSNHL) and to provide references for clinical treatment and prognosis assessment. Methods We included 232 ISSNHL patients with total deafness in Wenzhou Central Hospital from June 2015 to March 2017 using a prospective cohort design. Recording information including age, gender, hypertension, diabetes mellitus, vertigo, level of blood total cholesterol (TC), level of triglyceride (TG), level of low-density lipoprotein (LDL-C) and LDL/HDL ratio (LDL-C/HDL-C) were collected. Correlation between the prognosis of ISSNHL and blood total cholesterol were analyzed by univariable and multivariable logistic regression analysis. Results The clinical effective rate of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L was higher than that of patients with TC lower than 5.2 mmol/L (univariable: RR=6.49, 95%CI 3.16 to 13.30, P<0.001; multivariable-adjusted covariates: RR=6.15, 95%CI 2.66 to 14.3,P<0.001) with significant difference. No significant difference was found between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (univariable: RR=1.02, 95%CI 0.52 to 2.00,P=0.960; multivariable-adjusted covariates: RR=1.61, 95%CI 0.55 to 4.73, P=0.386). Gender-specific analysis showed for both male and female groups, the effective rates of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L were significantly higher than those of patients with TC lower than 5.2 mmol/L. There was no significant difference between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (P>0.05) in either male group or female group. Conclusion The current study suggests that patients with levels of TC ranging from 5.2 mmol/L to 6.2 mmol/L predicts the best prognosis.
ObjectiveTo explore the relationship of the level of inflammation and nutritional status with the occurrence and prognosis of refractory diabetic foot.MethodsA total of 70 patients with refractory diabetic foot between August 2015 and August 2017 were randomly selected as the observation group. Another 70 patients with diabetes mellitus (without foot ulcer) who visited the hospital in the same period were set as the control group. The observation group was subgrouped into the non-amputation group and the amputation group according to the follow-up endpoint events, and into the grade Ⅲ, Ⅳ, and Ⅴ groups according to Wagner classification method. The blood levels of inflammatory markers and nutritional markers between groups were compared.ResultsIn the observation group, vascular cell adhesion molecule-1 (VCAM-1), fibroblast growth factor 2 (FGF2), fibrinogen (FIB), tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-18, lipoprotein phospholipase A2 (LP-PLA2), C-reactive protein (CRP) levels were significantly higher than those in the control group, and albumin (ALB), prealbumin (PA), and transferrin (TRF) levels were significantly lower than those in the control group, with statistically significant differences (P<0.01). The blood levels of FGF2, FIB, IL-6, IL-18, LP-PLA2, and CRP in the amputation group were significantly higher than those in the non-amputation group, and the levels of TRF, ALB, and PA were significantly lower than those in the non-amputation group (P<0.01). There were statistically significant differences in the levels of FGF2, FIB, IL-6, IL-18, LP-PLA2, CRP, TRF, ALB, and PA in patients with diabetic foot with different Wagner grades (P<0.05). The result of multiple logistic regression analysis showed that IL-6 [odds ratio (OR)=1.487, 95% confidence interval (CI) (1.023, 2.120), P<0.001], IL-18 [OR=1.274, 95%CI (1.052, 1.665), P<0.001], LP-PLA2 [OR=1.478, 95%CI (1.126, 1.789), P<0.001], and CRP [OR=2.085, 95%CI (1.574, 2.782), P<0.001] were independent risk factors for the occurrence of refractory diabetic foot, and TRF [OR=0.645, 95%CI (0.002, 0.898), P<0.001], ALB [OR=0.838, 95%CI (0.429, 0.923), P<0.001], and PA [OR=0.478, 95%CI (0.201, 0.984), P<0.001] were independent protective factors for the occurrence of refractory diabetic foot.ConclusionIn the clinical treatment of diabetic foot, we should pay attention to the monitoring of the level of inflammatory factors and nutritional status, and it is necessary to timely carry out anti-inflammatory treatment and appropriate nutritional support treatment.
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 Heparanase can specifically cleave carbohydrate chains of heparan sulphate proteoglycans, which is an important component of the extracellular matrix. This study was designed to investigate the expression of heparanase in patients with colorectal cancer, and to analyze its relationships with progression of the cancer and clinical prognosis. Methods Samples were collected from 36 patients with colorectal cancers from 2003 to 2004 in Peking Union Medical College Hospital, and were embeded by Paraffin and fresh-frozened. The expression of heparanase mRNA and its protein were measured by RT-PCR and immunohistochemistry. The relationships between these expressions and the clinicopathologic information (tumor invasion, tumor differentiation, lymph node involvement, accompanying with colorectal adenoma and 2-year survival) were also evaluated. Results The expressions of heparanase mRNA in colorectal cancer (19/31， 61.3%) were significantly higher than those in normal colorectal tissues (6.5%). The overexpressions in normal tissues were positively correlated to the incidence of adenoma in patients with colorectal cancer （r=0.352， P=0.024）. The result of immunohistochemistry also showed that heparanase mainly expressed in the vascular endothelium within cancer tissues and the peripheral invased region outside cancer tissues. The 2-year disease-free-survival in patients with negative heparanase expression (88.9%) was higher than that with positive heparanase expression (50.0%), but there was no significant difference （P=0.078）. Conclusion Heparanase overexpressed in colorectal cancer tissues, and thus it may take a role as an indicator for the formation and prognosis of colorectal cancer.
Objective To summary the clinical experience of liver retransplantation （RLT）， and to improve the effect. Methods The clinical data of 62 cases who had received RLT in our institute from Jan. 2003 to Jun. 2012 were analyzed retrospectively. The survival rates of patients with different interval between two liver transplantation （LT） were calculated， and the data of patients who died and survived during perioperative period after operation were compared and analyzed. Results The 1-， 2-， and 5-year cumulative survival rates of 62 patients were 67.7%， 59.7%， and 56.4%， of early stage RLT patients were 38.5%， 38.5%， and 30.8%， of later stage RLT patients were 75.5%， 65.3%， and 63.3%， respectively. There were 28 patients died after operation， and 20 patients （71.4%） died during perioperative period， whose major cause of death were infection （65.0%， 13/20）， in addition， 4 cases （20.0%） died of multiple organ failure， 2 cased （10.0%） died of hepatic artery complication， 1 case （5.0%） died of portal vein complication. Eight cases （28.6%） died after perioperative period in reason of tumor recurrence. The model for end-stage liver disease （MELD） score 〔（26.95±9.28） score vs. （14.23±9.06） score〕， creatinine （Cr） level 〔（157.3±88.0） μmol/L vs.（69.8±35.9） μmol/L〕， international normalized ratio （INR） value 〔（1.676±0.744） vs.（1.124±0.286）〕， and total bilirubin （TBiL） value 〔431.8 μmol/L vs. 248.2 μmol/L〕 of patients died during perioperative period were higher than that of patients survived after perioperative period （P＜0.05）. The ratio of abnormal Cr of patients died during perioperativeperiod and survived after perioperative period were 60.0% （12/20） and 7.1% （3/42）， respectively. The 34 patients who had survived after perioperative period were all got followed-up for 3-104 months （average 49 months）. There were no tumor recurrence during the followed-up， and liver function of them were normal. Conclusions RLT is an effective method for irreversible graft failure after LT. Optimum operative time and reasonable individual immunosuppressive regimen to decrease the infection rate are all contribute to the increase of the survival rate.
ObjectiveTo observe the clinical features and visual prognostic factors of ethambutol-induced optic neuropathy (EON).MethodsA cohort study. Twenty-four inpatients (46 eyes) identified as EON in Neuro-Ophthalmology Department of Chinese PLA General Hospital from January 2014 to December 2017 were enrolled, including 14 males (26 eyes) and 10 females (20 eyes) with a ratio of 1.4/1 male/female. The average age was 42.79±15.12 years and the average weight was 62.46±12.31 kg. The average time duration between oral administration of ethambutol and occurrence of EON was 9.94±16.49 months. The average time of ethambutol duration was 7.06±11.68 months, with an average accumulative dose of 156.7±1 779.0 g and the average daily dose of 15.07±8.95 mg/(kg·d). All patients were tested with visual acuity, fundus photos, colour vision, OCT, visual field, VEP, orbital MRI and the gene of OPA1 and mitochondrial deoxyribonucleic acid (mtDNA). All the patients accepted drug withdrawal immediately after diagnosis, and were given the treatment of systemic nerve nutrition and improvement of microcirculation for 2 weeks. The time of follow-up was more than 12 months. According to whether the visual acuity (VA) in any of eyes was over than 0.1 at the last follow-up, all the patients were divided into two groups: the bad VA group (VA less than or equal to 0.1) and the better VA group (VA over than 0.1) group. The χ2 test and Fisher's exact probabilistic method test were used to compare the counting data between groups, and the Wlincox rank sum test was used to compare the measurement data. Multiple factors of VA outcome between the patients with bad or better va were analyzed by logistic regression.ResultsThirty eyes (65.2%) had VA less than or equal to 0.1 and 5 eyes (10.9%) had VA over than 0.5 at EON onset. The VA of the rest 11 eyes (23.9%) was higher than 0.1 and lower than 0.5. At the last follow-up, 20 eyes (43.5%) had VA less than or equal to 0.1 and 9 eyes (19.6%) had VA over than 0.5, the VA of the rest 17 eyes (36.9%) was higher than 0.1 and lower than 0.5. Fundus examination revealed 7 eyes (15.3%) with optic disc edema. OCT revealed significant loss of the retinal nerve fiber layer (RNFL) in the affected eyes, mainly in the temporal RNFL of the optic disc. All patients had dyschromasia, mainly in distinguishing the color of red and green. The types of visual field defect was as following: central dark spot (52.2%), diffuse visual acuity decreased (30.4%), temporal hemianopsia (17.4%). Orbital MRI revealed that 12/24 (50.0%) patients had T2 lesions with T1 enhancement in 6/24 patients (25.0%). Genetic test showed that 4 patients (16.7%) had gene mutation. Among them, there were 2 patients with OPA1 mutation, 1 with mtDNA 14340 point mutation and 1 with the mtDNA 11778 point mutation. Thirteen patients showed better VA outcomes (over than 0.1) while 11 showed bad VA outcomes after discontinuation of ethambutol. Between the better VA group and the bad VA group, there were statistically significant differences in the daily dose of ethambutol and gene mutation (P=0.031, 0.023). The daily dose was related to visual prognosis of EON while only the daily dose of more than 18 mg/(kg·d) may lead to bad VA outcomes according to the logistic analysis (95% CI 0.007-0.736, OR=0.069, P=0.027).ConclusionsEON may have OPA1 and mtDNA mutation with more bilateral eyes involved and less optic edema, which about 43.5% of the patients showed irreversible visual impact. The daily dose of ethambutol is related to the vision recovery.
To study the prognostic significance of proliferative cell nuclear antigen(PCNA)in bile duct carcinoma,expression of PCNA protein was studied immunohistochemically in 30 patients with bile duct carcinoma.Results:86.7 percent of bile duct carcinomas showed PCNA positive staining and significiant difference was observed between malignant and benign tissues.These results suggest that proliferative activity of malignant tissues was ber than that of the benign ones.In patients with cancer of stages 3,the mean survial time for those with high proliferative activity was 13 months in constrast with 26 months for those with low activity.PCNA is of prognostic significance for bile duct carcinoma patients.
ObjectiveTo analyze the curative effect and prognosis of drug resistant tuberculosis meningitis (TBM). MethodsRetrospective analysis was carried out on the clinical data of thirty-two cases of drug resistant tuberculous meningitis patients hospitalized from January 2010 to December 2015. And the prognosis of the patients was evaluated by meliorated Rankin Scale (mRS). ResultsThirty-one cases (96.9%) were improved in 32 patients with drug resistant TBM, and 1 case (3.1%) was ineffective. After treatment, one patient had hormone-related glaucoma and osteoporosis, and one patient had drug Cushing syndrome. Twenty-seven patients (84.4%) had an mRS score equal to or less than 2 points. ConclusionDrug resistant TBM is difficult to diagnose in the early stage, and the curative effect is satisfying with active anti-tuberculosis treatment.
Objective To investigate the clinicopathological characteristics of proximal gastric cancer (PGC). MethodsThe clinical course and pathologic feature of 118 PGC patients were analyzed, and compared with those of 310 distal gastric cancer (DGC) patients. ResultsThe incidence of PGC was lower than DGC, the percentage of Ⅲ,Ⅳ stages and undifferentiated type in the PGC group were significantly higher than in DGC. For the surgical procedure, patients in the PGC had significantly higher percentages of total gastrectomy and other organ resection than in DGC. The percentage of patients with positive margin and lymph node metastasis in PGC was also significantly higher than in DGC. Esophageal invasion and lymph node metastasis were much more in PGC. The 5year survival of patients with PGC was significantly lower than that with DGC. No significant differences were found between the two groups with respect to the mortality rates and complications. Conclusion The relatively poor prognosis associated with PGC is mainly from advanced cases and esophageal invasion. Early detection and treatment is the most important strategy to improve the survival of patients with PGC.
