ABSTRACT

The occurrence and development of the tumor are closely associated with the tumor microenvironment (TME) and host immune status. Traditional TNM staging has gradually been insufficient in the assessment of patients' outcomes, as the TNM system solely evaluated tumor cell characteristics and failed to predict clinical outcomes based on immune factors. Therefore, immunoscore (IS), derived from the concept of immune contexture, was proposed to establish a more comprehensive and accurate TNM-I staging above the TNM staging. Recently, increasing studies have shown that IS can predict the survival outcome and treatment efficacy more accurately than TNM staging. Moreover, IS possess characteristics such as feasibility, convenience, robustness and reproducibility, which make it possible for IS to be used as a biomarker for clinical application, to classify patients better and contribute to developing individualized treatment strategies, ultimately, to improve the overall survival of patients with cancer. This article reviews of the progress of immunoscore in predicting patients' prognosis and response to therapy among different tumors.

ABSTRACT

Objective To compare cognitive ,behavioral ,and psychological symptoms observed in Alzheimer's disease (AD ) and dementia with Lewy body (DLB ) in order to provide helpful information for differential diagnosis. Methods We selected 215 patients with AD (AD group)and 66 patients with DLB(DLB group)to retrospectively analyzed their general information ,family history , and disease history.The Mini-Mental State Examination(MMSE scale)was used to evaluate cognitive abilities and Neuropsychiatric Inventory ( NPI scale ) was used for analysis of behavioral and psychological symptoms of dementia in both groups. Results The prevalence of hypertension was higher in the AD group(52.6%,n=113)than in the DLB group(40%,n=24)(P<0.05).The DLB group showed better general cognitive scores ,disorientation scores ,immediate recall scores ,and delayed recall scores than the AD group. Fluctuating cognitive deficiencies and Parkinson's symptoms were more prevalent in the DLB group than in the AD group with 2 patients (0.9%) showing fluctuating cognitive deficiencies in the AD group ,and 19(28.8%)in the DLB group(χ2=8.580 ,P=0.003) ;with 26 patients(12.1%)showing Parkinson's symptoms in the AD group and 25(37.9%)in the DLB group(χ2= 22.602 ,P= 0.000).As to behavioral and psychological symptoms ,the DLB group had higher scores in total NPI ,hallucinations and nighttime abnormal behaviors with 32 patients (14.9%)showing hallucinations and 64 (29.8%)showing nighttime abnormal behaviors in the AD group ;30(46.2%)showing hallucinations and 30 (46.2%)showing nighttime abnormal behaviors in the DLB group (all P < 0.05 ) . Conclusions Hypertension is more prevalent in AD patients. Fluctuating cognitive deficiencies ,Parkinson's symptoms ,hallucinations ,and nighttime abnormal behaviors are prominent manifestations in DLB patients.

ABSTRACT

Objective To analyze the correlation between K-ras gene mutation and clinicopathological characteristics and prognosis of colorectal cancer patients with different primary sites.Methods The clinical and pathological records of 69 patients who were pathologically confirmed as colorectal cancer and tested K-ras gene status at Wuxi People's Hospital Affiliated to Nanjing Medical University between May 2007 and August 2017 were adopted.The correlation between clinicopathological characteristics and prognosis of colorectal cancer patients with different primary sites and K-ras gene mutation status were retrospectively analyzed.And the patients were visited to adopt the prognosis data and perform the Kaplan-Meier survival analysis.Results The K-ras mutation rate was 50.7%(35/69),including 40.0%(12/30)in left-side colon cancer,73.3%(11/15)in right-side colon cancer and 50.0%(12/24)in rectal cancer.The mutation rate of K-ras gene in patients ≥ 60 years old [61.5%(24/39)vs.36.7%(11/30),χ2= 4.197,P = 0.041] or serum CA19-9 raising up abnormally was conspicuously high [65.6%(19/29)vs.37.5%(15/40),χ 2= 5.486,P =0.019].Other clinicopathological characteristics,such as gender,lesion location,histological classification,TNM stage,serum CEA expression,clinical features had no correlation with K-ras gene mutation status(all P> 0.05).And no relationship was found between prognosis and overall survival of colorectal cancer patients with different primary sites and K-ras gene mutation status(χ 2= 0.001,P = 0.997; χ 2= 0.583,P =0.445).In general,the 5-year survival rate of left-side colon cancer patients was highest(76.9%),followed by rectal cancer(69.7%),and right-side colon cancer was lowest(31.3%).The primary site of colorectal cancer was related to the overall survival of patients(χ2=11.004,P =0.004).Conclusions K-ras gene mutation in colorectal cancer is closely related to age and serum CA19-9 levels of the patients.The prognosis of left-side colon cancer is best,rectal cancer second,and right-side colon cancer poorest.Whether K-ras gene mutation is the prognostic factor of colorectal cancer is not clear.Testing the K-ras gene status and serum tumor index expression,distinguish the primary site and age group will provide the theory basis and promote the clinical targeted therapy and improve the survival of colorectal cancer patients.

ABSTRACT

Cancelling drug price addition is one of public hospital reform content, under the condition of insufficient financial input, public hospitals should enhance the drug cost management, taking measures to reduce drug proportion, to deal with all kinds of hospital operation problems produced by hospital income decline due to the cancellation of drug addition. Through years of exploration and practice, Affiliated Hospital of Jining Medical University has controlled the rising of drug cost effectively and received better effect, which built a good foundation of public hospital reform.

ABSTRACT

Cystic liver metastasis, which lacks specific clinical manifestations and standardized treatment, rarely occurs after radical gastrectomy. This study presented two gastric cancer cases with cystic liver metastasis treated in Wuxi People's Hospital from September 2008 to November 2012. The two female patients were 66 and 65 years old, respectively. Poorly differentiated ulcerated adenocarcinoma classified as stage III B [Tumor, Node, and Metastasis Classification (T4aN2M0)] and clinical manifestations of abdominal distension and ascites were detected in both patients. Cyst fluids were subjected to cytological analysis. Results confirmed the presence of liver metastasis of gastric cancer. The two patients benefited from local intracavitary chemotherapy or systemic intravenous chemotherapy.

ABSTRACT

2,3,5,4'-tetra-hydroxystilbene-2-O-glucoside (THSG), the water-soluble active components extracted from dried tuber root of Polygonum multiflorum (Polygonaceae), can promote the release of nitric oxide (NO) from vascular endothelial cells and has strong antioxidation. The postconditioning's protection of THSG on cardiac ischemia-reperfusion injury and the mechanism were investigated. After reperfusion for 3 h following occlusion of rat left anterior descending coronary artery (LAD) for 30 min, SαT recovery speed, arrhythmia and cardiac infarct size were observed.The ischemic size and infarct size was identified by using Evans blue and TTC staining methods respectively. The results showed that the infarct size in THSG 7. 5 mg/kg postconditioning group was significantly decreased from 43.6 %±9.1 % in mode group to 16.5 %±6.5 % (P<0.01).SαT recovery was quicker and the incidence of arrhythmia (55.6 % vs 100 %, P<0.05) was significantly lower than in control group. The infarct size in THSG+glybenclamide group was greater than in THSG group, but equivalent to that in control group (46.8 %±9.8 % vs 43.6 %±9. 1 %, P >0. 05), SαT recovery speed slower and the incidence of arrhythmia also lower (33. 3 % vs 100 %, P<0. 01), suggesting that glybenclamide could abolish the effects of THSG postconditioning reducing the cardiac infart size. It was concluded that THSG administration before reperfusion could effectively alleviate the cardiac reperfusion injury and possessed the postconditioning effects of reducing cardiac infarct size, which might be related with the KATP channel opening.

ABSTRACT

To analyze the causes of failure in conventional treatment to refractory gastroesophageal reflux diseases (GERD) patients, 16 refractory GERD patients (group R) and 16 cases of GERD primarily diagnosed (group P) were studied. Endoscopy, pathologic examination and 14C urea breath test were conducted in every patient. 24 h ambulatory pH and bilirubin monitoring were performed with Digitrapper MK III and Synetics Bilitec 2000. It was found that esophagitis in group R was more severe than in group P. The rate of Helicobacter pylori infection in group R was significantly lower than in group P. Fraction time pH below 4.00 was not longer while the bile reflux represented by fraction time abs above 0.14 was greater for patients in the group R as compared with those in the group P. The mixed refluxes and pure bile refluxes between the two groups had significant difference. The reflux episodes in the group R mainly occurred during nights. These results indicated that severe esophagitis, especially Barrett's esophagus with complications makes it difficult to control GERD. Severe duodenogastroesophageal refluxes (DGER) are often accompanied by refractory GERD. Mixed refluxes aggravate the esophageal injuries. Pure bile refluxes and nocturnal refluxes may cause failure of administration of proton pump inhibitors (PPI) in the morning. Helicobacter pylori infection and acid refluxes may not be the direct cause of refractoriness. Individual refractory GERD patient without abnormal results on pH or bile reflux recently should be diagnosed again.

ABSTRACT

To determine the relationship between Barrett's esophagus (BE) and features of gastroesophageal acid reflux, 24 h esophageal pH monitoring was performed in 90 patients. The patients were divided into 3 groups: 31 subjects with BE, 21 with mild esophagitis and 38 with severe esophagitis. The following parameters were evaluated: the percentage time of pH 0.05). During supine position all the above parameters in BE were significantly different from those with reflux esophagitis (P < 0.05). It is concluded that the quantity of acid reflux is not an important factor in development of BE in gastroesophageal reflux (GER), and the acid reflux in supine position might be important in development of BE in GER.

ABSTRACT

To determine the relationship between Barrett's esophagus (BE) and features of gastroesophageal acid reflux, 24 h esophageal pH monitoring was performed in 90 patients. The patients were divided into 3 groups: 31 subjects with BE, 21 with mild esophagitis and 38 with severe esophagitis. The following parameters were evaluated: the percentage time of pH < 4; the number of reflux episodes over 5 min; the duration of longest episodes and DeMeester score over total period and the auterior three parameters in erect and supine position. All these parameters in BE were significantly different from those with mild esophagitis (P < 0.01) and not significantly different from those with severe esophagitis (P > 0.05). During supine position all the above parameters in BE were significantly different from those with reflux esophagitis (P < 0.05). It is concluded that the quantity of acid reflux is not an important factor in development of BE in gastroesophageal reflux (GER), and the acid reflux in supine position might be important in development of BE in GER.
