Objective To investigate the correlation between the prognostic nutritional index (PNI) and clinicopathological features and long-term prognosis of gastric cancer patients after radical gastrectomy.Methods The clinical data of 135 gastric cancer patients who underwent radical gastrectomy in this hospital from 2002 to 2006 was analyzed retrospectively.The PNI value was calculated by serum albumin (g/L) + 5 x lymphocyte count (× 109/L).The receiver operating characteristic (ROC) curve and Youden index was used to determine the cutoff value of the PNI.Survival curves were described by the Kaplan-Meier method and compared by the Log-rank test.The univariate and multivariate analyses were performed with the Cox proportional hazard model to identify the prognostic factors.Result The mean PNI value was 47.3 ± 5.9.The mean values of the PNI in age (t =2.909,P =0.004),tumor size (t =2.227,P =0.028),tumor depth (t =3.314,P =0.001),negative lymph node (t =2.381,P =0.019),negative lymphovascular invasion (t =2.781,P =0.006) were significantly higher than those in patients without such factors.When the PNI was 47,the Youden index was maximal,with a sensitivity of 70％ and specificity of 63％.The mean age in high PNI group was significantly lower than that in low PNI group (x2 =6.443,P =0.011).Tumor infiltration depth in high PNI group was less than in low PNI group (x2 =7.394,P =0.007).The proportion of lymphovascular invasion in high PNI group was significantly lower than in low PNI group (x2 =4.540,P =0.033).The overall survival rate in high PNI group was higher than in low PNI group (P =0.002).The univariate and multivariate analyses showed that tumor location (OR,2.144 ; 95 ％ CI 1.239-3.712 ; P =0.006),lymph node metastasis (OR,4.887 ; 95 ％ CI 1.856-12.866 ; P =0.001),lymphovascular invasion (OR,1.842 ; 95％ CI 1.078-3.145 ; P =0.025) and the PNI value (OR,2.282 ; 95 ％ CI 1.344-3.874 ; P =0.002) were independent factors for predicting overall survival rate.Conclusions The PNI value is a simple and useful tool to predict the prognosis of patients with gastric cancer.

ObjectiveTo characterize the gene expression in acute phase of irradiated oligodendrocytes (OL) in vitro.Methods The total RNA was extracted from irradiated OLs with 10 Gy by 6 MV X-rays at 1 and 4 h.The Affymetrix RAT 230 2.0 microarray were used to evaluate and screen the gene expression profile.The quantitative real-time RT-PCR was performed to validate the microarray results of selected myelin basic protein (MBP) and neural cell adhesion molecule 1 ( NCAM-1 ) genes.Results Compared with un-irradiated OLs,there were 1079 different expressed genes in irradiated cells.Those genes were classified in 79 categories based on the functional classification.Some familiar genes associated with OL cellular physiological process,apoptosis,cell cycle control,metabolism,cell communication and receptor binding were included.Compared with the microarray results,the coincidence rate of real-time RT-PCR was 91.7%.The down-regulation of MBP and up-regulation of NCAM 1 gene expression were confirmed.Conclusions Radiation-induced changes in gene expression in OLs took place in acute phase and influenced by time-course.The changes of MBP and NCAM1 gene expression may play a key role in the pathogenesis of radiation-induced demyelination.

AIM To explore the effects of Xuebijing Injection (Carthami Flos,Salviae miltiorrhizae Radix et Rhizoma,Paeoniae Radix Rubra,etc.) on serum CRP,TNF-α and IL-6 levels in patients with severe acute organophosphorus pesticide poisoning (AOPP).METHODS Seventy-two cases of patients with AOPP treated from Jan 2014 to Mar 2016 in the emergency department of our hospital were randomly divided into two groups,the control group treated with atropine,pralidoxime chloride and conventional treatment,and the observation group combined with Xuebijing Injection.The dynamic changes of serum CRP,TNF-α and IL-6 levels,and clinical curative effects were compared between the two groups.RESULTS The serum CRP,TNF-α and IL-6 levels in the two groups were decreased in turn before the treatment,at the 3rd,7th days after the treatment,and the serum CRP,TNF-α and IL-6 levels in the observation group were significantly lower than those in the control group;the dosage of atropine,time of cholinesterase activity recovered 60％ and hospital stay in the observation group were significantly less than those in the control group;the rebound rate of the observation group was lower than that of the control group.The acute respiratory distress syndrome (ARDS) rate in the observation group was significantly lower than that in the control group.All the differences had statistical significances (P ＜ 0.05).CONCLUSION Xuebijing Injection can effectively inhibit the inflammatory response,reduce the incidence of complications,shorten the course,and improve the clinical efficacy in the treatment of patients with AOPP.

Objective To observe the effect of preoperative oral administration of carbohydrate on blood glucose,insulin resistance(IR) and inflammatory reaction after gastrointestinal operation.Methods 48 patients receiving gastrointestinal operation were randomly divided into the study group(n =23)and the control group(n =25).Patients in the study group were orally given 25％ glucose solution 300 ml 3 hours before operation.Before anesthesia induction,gastric contents were aspirated through nasogastric tube to examine its volume and pH.Serum high sensitivity C-reactive protein(hsCRP),fasting blood glucose,insulin level and homeostasis model assessment-insulin resistance(HOMA-IR) were detected before operation and on the first morning after operation between the two groups.Results No anesthesia or operation related complications occurred in either groups.Patients had similar gastric contents volume and the PH value of gastric contents.There was no significant difference in serum hsCRP,fasting blood glucose and HOMA-IR between the two groups before operation.But on the first day,fasting blood glucose,HOMA-IR and hsCRP were significantly lower in the study group than in the control group(6.51 ±1.15 vs 7.49 ±0.57 mmol/L,P =0.038;4.34 ± 1.60 vs 6.09 ±2.81,P =0.043;40.45 ± 27.02 vs 80.02 ± 38.98 mg/L,P =0.03).Conclusion Preoperative oral administration of carbohydrate can obviously lower the postoperative blood glucose level and insulin resistance and alleviate postoperative inflammatory reaction.

Objective:To analyze the short-term clinical outcomes of total laparoscopic distal gastrectomy (TLDG) and laparoscopic-assisted distal gastrectomy (LADG) combined with Billroth-Ⅱ+Braun anastomosis.Methods:Clinical characteristics of patients undergoing laparoscopic distal gastrectomy combined with Billroth-Ⅱ+Braun anastomosis at Department of Gastrointestinal Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University from Jan 2020 to Oct 2022 were analyzed. Patients were divided into TLDG group ( n=62) and LADG group ( n=62) according to the surgical approach. Results:There were significant differences in the preoperative clinical data section between the two groups, and 124 patients (62 in each group) were enrolled after using propensity score matching to balance significant variables. Compared with the LADG group, the TLDG group showed statistically differences in time to first venting [(2.9±1.3) vs. (2.3±0.8) d, Z=-3.072, P=0.002], time to first fluid diet [(5.9±1.3) vs. (5.4±1.4) d, Z=-2.031, P=0.042] and incision length [(7.1±1.4) vs. (4.8±0.8) cm, Z=-6.331, P=0.000]. Total postoperative complication rate in the TLDG group and the LADG group (29% vs. 37%, χ2=0.911, P=0.340) was not statistically significant. Incidence of postoperative pneumonia was lower in the TLDG group than in the LADG group (3% vs. 13%, χ2=3.916, P=0.048), and incidence of all remaining postoperative complications were not statistically significant. There was no statistically significant difference in the incidence of serious postoperative complications between the TLDG and LADG groups ( P=1.000). Multifactorial analysis revealed that male ( P=0.023) and age ≥65 years ( P=0.001) were independent risk factors for postoperative complications. Conclusion:TLDG is safe and feasible and has better short-term clinical efficacy than LADG.

Objective To analyze the etiological characteristics of human Brucella strains isolated, and to improve the precision in control and prevention of brucellosis. Methods In 2016, blood samples were collected from patients in Jingyuan County Gansu Province, and tested via the Rose-Bengal Plate Agglutination Test (RBPT) and the tube agglutination test methods,and serological positive blood samples were inoculated to bidirectional blood culture bottle for culturing, and further identified by traditional biological classification method and the Brucella abortus, Brucella melitensis, Brucella ovis, and Brucella suis species-specific PCR (AMOS-PCR). Multiple-locus variable number tandem repeat sequence analysis (MLVA) -16 was used to detect molecular typing and do cluster analysis. Results The isolated strain was identified by the traditional biological classification method, bacteria could grow in thionine and reddened dye, A and M factors agglutination tests were positive, Bk2phage treatment of bacterial strain cracking, but Tb, Wb phages were not cracked. AMOS-PCR amplification result showed a 731 bp band, which was a strain of Brucella melitensis. The results of MLVA-16 showed that there was a difference in the number of repeats on some Variaable Number of Tandem Repeat(VNTR)sites of the isolated strain. Clustering analysis showed that, the isolated strain was clusted into the same clade with the clustering of Brucella melitensis type 3 from GS-201605 in Gansu. And the clustering was similar compared with that of Zhejiang, Guangdong, Fujian and Yunnan. Conclusion Human brucellosis is a inputting transmission in Gansu Province, there is a genetic variation of genotype 3 sheep Brucella between Gansu Province and other domestic provinces.

OBJECTIVETo investigate and analysis the clinical and pathological characteristic of gastrointestinal stromal tumor (GIST) patients, and to clarify the factors that effect on prognosis.

METHODSThe clinical and pathological features and follow-up of GIST patients who received surgery in Peking Union Medical College Hospital from May 2002 to December 2013 were analyzed retrospectively. The prognosis was evaluated by univariate and multivariate analysis. Kaplan-Meier unvariate analysis and Log-rank test were used to compare the survival rates. Multivariate factors for survival were analyzed by Cox proportional hazards regression model.

RESULTSA total of 558 GIST patients were collected, including 284 males and 272 females. The high incidence was in the elderly and age of 50 to 70 years. Most of the primary tumors are located in stomach (303 cases), followed by the small intestine (118 cases). Surgical procedures included R0 resection in 517 cases, R1 resection in 4 cases, R2 or palliative resection in 37 cases. The recurrence risk was very low in 102 cases, low in 156 cases, moderate in 67 cases and high in 233 cases. Of all the patients, 495 cases completed the follow-up, the follow-up rate was 88.7%. Five year survival rate was 87.4%. Patients who took targeted therapy with moderate and high risk of recurrence had a better prognosis compared with not taking the drug. Univariate analysis revealed that the factors impacting the prognosis were age, tumor size, tumor site and mitotic count. Multivariate analysis showed that tumor size (P=0.01, RR=1.562, 95% CI: 1.452 to 15.664), location (P=0.01, RR=1.552, 95% CI:1.324 to 12.225), mitotic figures (P<0.01, RR=1.415, 95% CI: 2.126 to 7.968) and tumor rupture (P=0.01, RR=1.578, 95% CI: 1.543 to 15.892) were independent prognostic factors.

CONCLUSIONR0 resection combined with targeted therapy is the best treatment of GIST. Tumor size, location, mitosis count and tumor rupture are independent prognostic factors of GIST patients.
