Time and so on were better than the control group, the adverse reaction rate were lower than the control group, there were significant differences between the groups (P<0.05) .Conclusion Severe bronchial asthma patients choose conventional methylprednisolone treatment significantly, in a short period of time can effectively improve the clinical symptoms and the adverse reaction is less, it is widely used in clinical treatment of severe bronchial asthma patients.

Naringin has been reported to possess a wild range of biological activities. However, the route and metabolites of naringin produced by intestinal bacteria are not well understood. In this paper, different bacteria were isolated from human feces and their abilities to convert naringin to different metabolites were studied. Ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) with automated data analysis software (MetaboLynx) was applied to fast analysis of naringin metabolites. Using MSE and mass defect filter techniques, three metabolites were detected and tentatively identified. The results indicated that acetylation, hydrolyzation and hydrolyzation with hydrogenation were the major metabolic pathways of naringin in vitro. Then, we studied the gene sequence of the 16S rRNA of the bacteria by extraction of genomic DNA of the strain, PCR amplification and clone of the 16S rRNA. The consequence proved that Enterococcus sp.30, Bacillus sp.46, Escherichia sp.54 and Escherichia sp.63 have the peculiar metabolism characteristic of naringin.

Objective To evaluate the effect of virtual reality on motor function in patients with stroke. Methods PubMed, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure (CNKI), VIP Database for Chinese Technical Periodicals and Wanfang Data were searched for the randomized controlled trials (RCTs) of virtual reality on motor function in patients with stroke from the date of establishment to January 2013. The included studies were evaluated according to the method recommended by the Cochrane Collaboration. RevMan 5.0 software was used to analyze the extracted data. Results 20 trials were included (13 trials about the upper extremity function and 7 trials about the lower extremity function). Compared with conventional training, the virtual reality training significantly increased the score of Fugl-Meyer assessment (FMA) (WMD=4.27, 95%CI: 2.47~6.06, Z=4.67, P<0.00001) and Box and Block Test (BBT) (WMD=9.29, 95% CI: 5.24~13.34, Z=4.50, P<0.00001). However, the results of Berg balance scale (BBS) (WMD=1.63, 95% CI: -0.83~4.09, Z=1.30, P=0.20) and walking speed (WMD=0.01, 95%CI: -0.14~0.17, Z=0.18, P=0.86) were not statistically significance for the lower extremity function. According to the Jadad Score of included studies, 16 of them were of low quality and only 4 of them were of high quality. Conclusion The virtual reality training could improve the upper extremity function in patients with stroke, but not for the lower extremity function.

Objective To estimate the value of contrast-enhanced harmonic endoscopic ultrasonography(CEH-EUS)on differential diagnosis of pancreatic mass. Methods Multiple Chinese and English databases were retrieved to selected relevant literature.The quality of literature was assessed,and the data were meta-analyzed using Metadisc 1.4 and STATA 14.0 software. Results A total of 16 researches with 1 352 patients were included. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio,and diagnostic odds ratio was 93%(95%CI: 92%-95%), 84%(95%CI:80%-87%), 5.82(95%CI: 4.06-8.33), 0.08(95%CI: 0.06-0.10), and 77.33(95%CI: 52.37-114.17), respectively. The area under the summary receiver operating characteristic curve was 0.96(95%CI: 0.94-0.97). The results of subgroup analysis demonstrated that the number of cases, region, QUADAS scores, the diameter and type of mass,and the experience of diagnostician were not the source of heterogeneity.After 2 articles with larger bias were eliminated,the heterogeneity dropped to an acceptable range,and the pooled sensitivity,specificity,positive predictive value and negative predictive value had no significant change. All these suggested that the results of meta-analysis were reliable. Conclusion CEH-EUS has a high accuracy in differential diagnosis of pancreatic mass,and can be used as an effective diagnostic method.

Objective: To explore preoperative predictive markers for invasive malignancy in intraductal papillary mucinous neoplasm(IPMN). Methods: The retrospective case-controlled study was adopted.Seventy-nine patients who underwent surgery and with pathologically confirmed IPMN from January 2005 to December 2014 at Department of Pancreatic Surgery, Zhongshan Hospital Fudan University were enrolled.Forty-six patients were male and 33 were female,with an average age of (62.9±8.9)years (range:37-82 years).Tumor sites:56 tumors were located at the head of the pancreas,22 were located at the body and tail of the pancreas,and 1 was located across the whole pancreas.Surgical procedures: 51 patients underwent pancreaticoduodenectomy, 22 patients underwent distal pancreatectomy, 4 patients underwent segmental pancreatectomy and 2 patients underwent total pancreatectomy.IPMNs were classified into non-invasive lesions and invasive carcinomas according to the histopathological findings of the tumor.Thirty-two tumors were non-invasive lesions and 47 were invasive carcinomas.The preoperative findings were compared between patients with non-invasive IPMN and patients with invasive carcinoma by univariate analysis using t test and χ² test accordingly,and factors with statistically significance were subsequently submitted to multivariate analysis. Results: Univariate analysis showed that tumor size(P=0.022), carcinoembryonic antigen(P=0.012), CA19-9(P=0.011), lymphocytes(P=0.034), neutrophil-to-lymphocyte ratio(P=0.010)and platelet-to-lymphocyte ratio(PLR)(P=0.004)were predictive markers with statistical significance.Multivariate analysis showed that CA19-9(P=0.012)and PLR(P=0.025) were independent predictive markers for invasive malignancy in IPMN.The area under curve of the combination factor of CA19-9 and PLR(0.864) was larger than that of CA19-9(0.806) or PLR(0.685) alone, and all the authentic indicators of the combination factor were better than those of each alone. Conclusions CA19-9 and PLR are independent predictive markers for invasive malignancy in IPMN.The combination of CA19-9 and PLR has improved efficacy than each alone.

Objective:To investigate the treatment and prognosis of patients of G3 non-functional pancreatic neuroendocrine tumors (pNETs) with proliferation index of Ki-67 <55%.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 15 G3 non-functional pNETs patients with proliferation index of Ki-67<55% who were admitted to Zhongshan Hospital of Fudan University from April 2014 to April 2020 were collected. There were 11 males and 4 females, aged (58±10)years. All patients underwent radical resection of the primary lesion. Obser-vation indicators: (1) treatment; (2) postoperative pathological characteristics; (3) follow-up. Measure-ment data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( Q1, Q3) or M(range). Count data were described as absolute numbers. The Pearson correlation analysis was used to verify the correlation between variables. Kaplan-Meier method was used to draw survival curve and calculate survival rate. Log-Rank test was used for survival analysis. Results:(1) Treatment. All 15 G3 nonfunctional pNETs patients underwent radical resection of the primary lesion of pancreas, including 5 cases receiving pancreati-coduodenectomy, 10 cases receiving distal pancreatectomy with splenectomy. There were 5 patients with simultaneous liver oligometastasis who underwent combined segmental (lobectomy) hepatectomy. All 15 patients had negative tumor margin, and the operation time and volume of intraoperative blood loss of 15 patients was 120(90,210)minutes and 200(50,300)mL, respectively. None of patient had complications ≥Ⅲ grade of the Clavien-Dindo classification during the postoperative 30 days. Of the 15 patients, there were 5 cases receiving comprehensive treatment based on CAPTEM chemo-therapy (temozolomide combined with capecitabine), 2 cases receiving local interventional therapy, 2 cases receiving CAPTEM chemotherapy, 1 case receiving local interventional therapy combined with molecular targeted therapy, 1 case receiving local interventional therapy combined with long acting somatostatin therapy, 1 cases receiving long acting somatostatin therapy combined with molecular targeted therapy, and 3 cases without postoperative treatment. (2) Postoperative patholo-gical characteristics. The tumor diameter of 15 patients was 3.3(range, 0.5-6.0)cm. There were 2 cases with tumor diameter <2 cm, 13 cases with tumor diameter ≥2 cm. The number of lymph nodes dissected and number of lymph nodes metastatic was 6(4, 10) and 2(1,3) in 15 patients, respectively, including 12 cases with positive lymph node metastasis. Of the 15 patients, there were 5 cases with tumor invasion of adjacent organ, 5 cases with simultaneous liver metastasis, 8 cases with perineural invasion and 8 cases with vascular invasion. There were 3, 7, and 5 patients with stage Ⅱ, stage Ⅲ, and stage Ⅳ of pathological TNM staging, respectively. The proliferation index of Ki-67 and mitotic count was 32%±9% and (11±9)/10 high power field in the primary lesion of 15 patients, respectively, and there was no correlation between proliferation index of Ki-67 and mitotic count ( P>0.05). (3) Follow-up. All 15 patients were followed up after surgery for (55±24)months. The median survival time of 15 patients was 78(range, 43-113)months, with 1-, 3-, 5-year overall survival rate as 100%, 92%, 62%, respectively. During the follow up, 9 of the 15 patients underwent tumor recurrence, with the recurrence time as 20(14, 44)months. There were 8 patients died of tumor recurrence or metastasis. The median survival time was 86(range, 51-120)months in 5 patients receiving comprehensive treatment based on CAPTEM chemotherapy, versus 53(range, 45-60)months in 10 patients receiving other postoperative adjuvant therapy or without postoperative treatment, showing a significant difference between them ( χ2=4.21, P<0.05). Conclusion:The prognosis of patients of G3 nonfunctional pNETs with proliferation index of Ki-67<55% undergoing radical resection combined with postoperative comprehensive treatment based on CAPTEM chemotherapy in better than that of patients receiving other postoperative adjuvant therapy or without posto-perative treatment.

Objectives:To evaluate the role of pancreas multidisciplinary team(MDT) clinic in the diagnosis of pancreatic diseases,patient compliance with MDT advice,and the impact of MDT on the postoperative survival of patients with pancreatic cancer.Methods:The study included 927 patients(554 males,373 females,aged (58.1±13.3)years (range: 15 to 89 years)) that had visited the pancreas MDT clinic of Zhongshan Hospital from May 2015 to December 2021,and 677 patients(396 males, 281 females, aged (63.6±8.9)years(range: 32 to 95 years)) who underwent radical surgery and with pathologically confirmed pancreatic adenocarcinoma from January 2012 to December 2020,of whom 79 patients had attended the pancreas MDT. The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. The Kaplan-Meier method was used for drawing the survival curve and calculating the survival rate. The univariate analysis was done by Log-rank test and the multivariate analysis was done by COX proportional hazards model. Survival rates were compared using χ 2 test. Results:Among the 927 patients that had visited the MDT clinic,233 patients(25.1%) were referred due to undetermined diagnosis. A direct diagnosis was made in 109 cases (46.8%,109/233) by the MDT clinic, of which 98 were consistent with the final diagnosis,resulting in an accuracy of 89.9%(98/109). The direct diagnosis rate in the recent years(36.6%(41/112),from June 2019 to December 2021) decreased compared to that in the previous years(56.2%(68/121),from May 2015 to May 2019),yet the accuracy in the recent years(90.2%,37/41) was basically the same as before (89.7%,61/68). The rate of compliance of the entire cohort was 71.5%(663/927), with the compliance rate in the recent two and a half years(81.4%,338/415) remarkably higher than that in the previous four years(63.4%,325/512). Patients with pancreatic cancer that attended the MDT exhibited a trend toward longer median postoperative survival than patients that did not attend the MDT,but the difference was not statistically significant(35.2 months vs.30.2 months, P>0.05). The 1-year and 3-year survival rates of patients that attended the MDT were significanly higher than patients that did not attend the MDT(88.6% vs. 78.4%, P<0.05;32.9% vs. 21.9%, P<0.05,respectively),but the 5-year survival rate was not statistically different(7.6% vs. 4.8%, P>0.05). Conclusions:The pancreas MDT clinic is an accurate and convenient way to diagnose intractable pancreatic diseases,and in the recent years the patients′ compliance rate with MDT advice has increased. Pancreatic cancer patients that have attended the MDT have higher 1-year and 3-year postoperative survival rates,but the long-term survival benefits of MDT still needs to be proved by clinical studies on a larger scale.
