Objective To investigate the related factors of early adverse outcomes in young patients with ischemic stroke.Methods From January 2006 to June 2016,685 young patients (18-45 years old) with acute ischemic stroke admitted to the Department of Neurology,Nanjing General Hospital of Nanjing Military Command were enrolled retrospectively.They were diagnosed as the first onset with head CT or MRI.According to the modified Rankin scale (mRS) at 90 d,the patients were divided into a favorable outcome (mRS 0-2) group (n=554) and a poor outcome (mRS 3-6) group (n=131).The collection of clinical data were completed on the day of admission,including the risk factors for cerebrovascular disease (oral contraceptives,etc),the National Institutes of Health stroke scale (NIHSS) score on admission,the mean systolic blood pressure (>140 mmHg was analyzed) and laboratory examination.The stroke subtypes were classified with the trial of org 10172 in acute stroke treatment (TOAST) classification criteria.Univariate analysis was used to analyze the difference of clinical data between groups,and multivariate logistic regression analysis was used to analyze the risk factors for early poor outcomes.Results Compared with the favorable outcome group,the patients with the ratio of mean systolic pressure >140 mmHg in the first 3 d after hospitalization (37.4% [49/131] vs.21.7% [120/554],χ2=14.131),NIHSS score on admission (10.0 [7.0,14.0] vs.1.5 [0,3.0],Z=-15.300),white blood cell count (7.5 [6.0,9.0] ×109/L vs.6.8 [5.7,8.2] ×109/L,Z=-3.157),fasting glucose (4.9 [4.6,6.0] mmol/L vs.4.8 [4.4,5.3] mmol/L,Z=-2.726),higher fibrinogen level (2.8 [2.3,3.4] g/L vs.2.6 [2.3,3.2] g/L,Z=-2.018,blood uric acid level (291[220,346] mmol/L vs.315 [261,374] mmol/L,Z=-3.443),and plasma albumin level (43.1[40.0,45.9] g/L vs.44.8 [42.4,47.4] g/L,Z=-4.708) were decreased in the poor outcome group.There were significant differences between the two groups (all P<0.05).TOAST classification comparison:the proportion of the patients with cardioembolism in the poor outcome group was higher than that in the favorable outcome group.There was significant difference between the two groups (6.9% [9/131] vs.2.5% [14/554];χ2=4.893,P<0.05).There were no significant differences in the remaining clinical data between the two groups (all P>0.05).Multivariate logistic regression analysis showed that the higher NIHSS score on admission (OR,1.474,95%CI 1.378-1.576,P<0.01),the mean systolic pressure >140 mmHg at the first 3 d after admission (OR,2.134,95%CI 1.210-3.764,P=0.009) and the cardioembolism(OR,4.902,95%CI 1.073-22.222,P=0.040) were the risk factors for early poor outcome,and the elevated plasma albumin level (OR,0.902,95%CI 0.850-0.956,P=0.001) was a protective factor of early favorable outcome.Conclusion The higher NIHSS score at admission,the cardioembolism and the increased mean systolic blood pressure in the first 3 d after admission may result in early poor outcome in young patients with ischemic stroke,while the elevated plasma albumin level is beneficial to the early outcome.

BACKGROUND: Blood hemoperfusion with resin adsorption can clean larger molecules that exceed the molecular weight cutoff of combined continuous veno-venous hemofiltration (CVVH). Hence blood hemoperfusion with resin adsorption combined CVVH (HP+CVVH) has higher ability of mediator clearance, and can improve clinical outcomes in theory. This study aimed to investigate the effect of blood hemoperfusion with resin adsorption combined continuous veno-venous hemofiltration (HP+CVVH) on plasm cytokines like TNF-α, IL-1β, IL-6, cellular immunity and prognosis in patients with multiple organ dysfunction syndrome (MODS). METHODS: This was a prospective, randomized clinical trial. A total of 30 patients who had been diagnosed with MODS were enrolled in this study. Patients were randomly allocated to routine treatment+HP+CVVH group (treatment group) and routine treatment+only CVVH group (control group). In the treatment group, patients received blood hemoperfusion with resin adsorption for 2 hours, and then received CVVH for 10 hours every day. In the control group, patients received CVVH for 12 hours only every day. The patients in the two groups received blood purification therapy for three days. The plasma of patients in the treatment group was obtained at 0, 2, 12, 24, 26, 36, 48, 50, 60 hours, 5th day, 7th day and 10th day, respectively. The plasma of patients in the control group was obtained at 0, 12, 24, 36, 48, 60 hours, 5th day, 7th day and 10th day, respectively. APACHE II score, T-lymphocytes subpopulations, blood lactate acid concentration, heart rate, breathing rate, and oxygenation index were observed. RESULTS: Plasma cytokines like TNF-α, IL-1β, IL-6 decreased markedly after HP (P<0.01);T-lymphocytes subpopulations CD3+, CD4+, CD8+, CD4+/CD8+ increased after HP+CVVH or only CVVH. The plasma concentrations of TNF-α, IL-1β and IL-6 in the two groups were not markedly different at 12, 36, and 50 hours. But on the 5th day, the plasma concentrations of TNF-α, IL-1β and IL-6 in the treatment group were lower than those in the control group (P<0.05). On the 28th day, 5 patients died in the treatment group, and 6 patients in the control group. CONCLUSIONS: Both HP+CVVH and CVVH can clean plasma cytokines like TNF-α, IL-1β, and IL-6, and improve cellular immunity and clinical symptoms and signs of patients. Compared with only CVVH, the plasma concentrations of TNF-α, IL-1β and IL-6 were lower on the 5th day, and patients have an increased survival rate on the 28 day in the HP+CVVH group.

OBJECTIVETo compare the clinical and oncological outcomes between laparoscopic and open intersphincteric resection in patients with low rectal cancer.

METHODSFrom January 2007 to January 2010, patients with low rectal cancer treated by laparoscopic or open intersphincteric resection were included in a retrospective comparative study. Patients were classified into laparoscopy group (n=27) and open group (n=41). The operative procedures, postoperative complications, anal function and clinicopathological data were compared.

RESULTSCompared to the open group, the laparoscopic group had longer operative time [(242.2±42.5) min vs. (199.1±44.3) min, P=0.000], less blood loss [(150.5±102.2) ml vs. (258.4±149.2) ml, P=0.002], faster recovery of bowel function [(2.9±1.1) d vs. (3.6±1.5) d, P=0.032] and resumption of regular diet [(6.6±1.2) d vs. [(7.5±1.7) d, P=0.012], and shorter postoperative hospital stay [(7.7±1.4) d vs. (9.1±2.4) d, P=0.006]. The postoperative complication rate between the laparoscopic and open groups was not significantly different [18.5% (5/27) vs. 19.5% (8/41), P=0.464]. Oncological parameters were comparable between the two groups including lymph node harvested [(14.1±4.1) vs. (16.4±6.8), P=0.113], distal resection margin [(1.4±0.7) cm vs. (1.6±0.8) cm, P=0.311], and circumferential margin [7.4% (2/27) vs. 2.4% (1/41), P=0.709]. Local recurrence rates in laparoscopic and open groups were 7.4% (2/27) and 2.4% (1/41), and distant metastasis rates were 0 and 4.9% (2/41) respectively, and the differences were not significant (both P>0.05).

CONCLUSIONSLaparoscopic intersphincteric resection possesses same efficacy of open intersphincteric resection with less blood loss, shorter recovery time and hospital stay, and similar oncological outcomes, and no increased postoperative morbidity and mortality.

OBJECTIVETo investigate the role of Pediatric Critical Illness Score (PCIS) in evaluating the prognosis and severity of severe hand-foot-mouth disease (HFMD).

METHODSThis study included 424 children with severe HFMD, consisting of 390 survivors and 34 deceased patients. Related physiological parameters and clinical data were collected for calculating PCIS scores. The area under receiver operating characteristic curve (AUC) was employed to assess the performance of PCIS in evaluating the complications and outcomes.

RESULTSThe median of PCIS scores for survivors was higher than that for deceased patients (P<0.01). Of the 424 children with severe HFMD, only 26 (6.1%) had critical illness according to the severity assessment using PCIS. The AUC (95%CI) of PCIS was 0.74 (0.66, 0.82) in predicting pulmonary edema, 0.82 (0.74, 0.90) in predicting pulmonary hemorrhage, and 0.83 (0.75, 0.92) in predicting death.

CONCLUSIONSPCIS can predict the complications and prognosis in children with severe HFMD. However, the existing scoring system of PCIS cannot fully assess the severity of HFMD.

OBJECTIVETo study the individual surgical treatment of nasopharyngeal angiofibroma.

METHODSBetween Feb. 1989 and Oct. 2004, different kinds of surgical approaches in 51 patients with angiofibromas were retrospectively analysed. Using Fisch stage: thirty three cases were in stage I and II, 22 cases via palatal approach, 11 cases via endoscopic surgery;18 cases were in stage IIN and IV, 9 cases via lateral rhinotomy approach, 4 cases via midfacial degloving approach + Lefort I approach or modified maxillotomy, 5 cases via craniofacial approach. Twenty three cases accepted the embolization of the artery which feed the tumor, 7 cases in stage IV, 8 cases in stage IlI, 5 cases in stage II, 3 cases in stage I.

RESULTSThe average of blood loss was 1010 ml in operation but it became 200 - 870 ml (the average of blood loss was 485 ml) when had a selective preoperative embolization. The blood loss of none selective preoperative embolization was 500 - 3500 ml (the average of blood loss was 1600 ml), t = 7. 48, P < 0.05, the average of blood loss of selective preoperative embolization is less than the average of blood loss of none selective preoperative embolization. After 9 to 48 months of operation (the average time was 26.4 months), 8 cases recurred one time and 2 cases recurred two times.

CONCLUSIONSThe preoperative embolization could reduce the amount of bleeding during operation. In patients who are in stage I and II, searching endoscopic surgery could avoid the effect on craniofacial development which traditional surgical procedure did. For patient who are in stage III and IV, midfacial degloving approach and Lefort I approach or modified maxillotomy are not only good for exclusive resection of the tumor but also have less effect on articulation and beautiful cosmetic outlook.

OBJECTIVETo assess the performance of pediatric risk of mortality (PRISM), pediatric index of mortality 2 (PIM2) in predicting mortality in critically ill pediatric patients via a prospective study.

METHODThe outcome and the variables required to calculate PRISM and PIM2 were collected. The efficiency of PRISM and PIM2 in differentiation between death and survival by calculating the area under the receiver operating characteristic curve (ROC). Calibration across deciles of risk was evaluated using the Hosmer-Lemeshow goodness-of-fit χ(2) test.

RESULTA total of 412 critically ill pediatric patients transferred to Hunan Children's Hospital during August 1, 2012 and May 31, 2013 were enrolled in the study, and more than two-thirds of the children were suffering from respiratory and miscellaneous diseases; 45 (10.9%) inter-hospital transport of critically ill pediatric patients died at the time of hospitalization. The expected number of deaths were 45.01 by PRISM, and the expected number of deaths were 44.99 by PIM2. The expected mortality rate was 10.9% for PRISM or PIM2. The standardized mortality rate was 1.000 (0.710-1.290) for PRISM and 1.000 (0.710-1.290) for PIM2. The Hosmer-Lemeshow test gave a chi-square of 8.75 (P=0.364) for PRISM and 22.75 (P<0.05) for PIM2, PRISM had better fitting with the actual mortality than PIM2. The area under the receiver-operating characteristics (ROC) curve (95% confidence intervals, CI) were 0.829 (0.768-0.890) for PRISM and 0.758 (0.667-0.849) for PIM2.

CONCLUSIONAlthough the PIM2 test is less well calibrated overall, both PRISM and PIM2 can offer a good capacity for discriminating between survivors and moribund patients. The good performance of PRISM and PIM2 are demonstrated in predicting mortality probability in critically ill pediatric patients.

The industry of germ-free animals has been a hot spot in research along with the rapid development of studies on the relationship between microbiota and host diseases. Because it is pathogen?free, and the high degree of simi?larity in anatomy, physiology, pathogenesis to humans, germ?free pig is considered a clinical relevant model to be widely used in life science research. Based on the current state of research of germ?free pig cultivation at home and abroad and the experimental studies carried out in our laboratory as well, this article gives a simple discussion on germ?free technique of domestic pigs.

OBJECTIVETo summarize the reasons for bile duct injury (BDI) after laparoscopic cholecystectomy (LC), and to determine the effect of multiple treatment after BDI.

METHODSA retrospective cohort study was performed. The medical records of 110 patients diagnosed with BDI after LC from October 1993 to November 2007, in ten large hospitals in Guangdong of China, were reviewed.

RESULTSAmong 110 patients with BDI, 58 cases (52.7%) were local patients, whereas 52 cases (47.3%) were transferred from outside hospitals. Reasons for BDI following LC were: (1) Lack of experience of the LC operator (48.2%); (2) LC performed during acute cholecystitis (20.0%); (3) The structure of Calot triangle was unclear (15.5%); (4) Variable anatomical position (11.8%); (5) Intra-operation bleeding (4.5%). The commonest sites of injury were the choledochus and common hepatic duct (76.4%). Following BDI, endoscopic stenting or operative repair was performed in 106 patients. The overall success rate was 95.3% (101/106), with a mortality rate was 0.9% (1/106). Cholangitis occurred in 3.8% (4/106) cases. Choledocho-enterostomy operation was performed in almost 60.0% (63/106) cases, and the success rate was 93.7% (59/63). Endoscopic stenting or operative repair was performed immediately following BDI in 23.6% (25/106) patients, the success rate was 100%; and within 30 days in 63.2% (67/106) patients. Eighty-eight out of 106 patients who underwent repair were successful following the first operative procedure.

CONCLUSIONSFactors such as an un-experienced operator and unclear anatomical position were causes of BDI following LC. Early operative repair should be regarded as the treatment of choice, in patients diagnosed with BDI. Early refer to an experienced hepatobiliary operator ensures a high success rate.

OBJECTIVETo investigate the effect of dietary calcium on plasma lipoprotein profile in castrated and ovariectomized hamsters.

METHODSMale, castrated, female and ovariectomized hamsters (n=36 each group) were randomly divided into three sub-groups (n=12) and fed one of the three diets containing 0, 2, and 8 g calcium per kg diet for a period of six weeks. Changes in plasma lipoprotein profile were monitored at the end of week 0, 3 and 6.

RESULTSPlasma total cholesterol (TC), non-high density lipoprotein cholesterol (non-HDL-C), triacylglycerols (TG) and TC/HDL-C were decreased only in intact female and ovariectomized hamsters. In contrast, three levels of dietary calcium had no effect on lipoprotein profiles in both intact male and castrated hamsters.

CONCLUSIONBeneficial modification of lipoprotein profile by dietary calcium was gender-dependent at least in hamsters.

Xinshenghua Keli is known as the "preferred prescription of postpartum", with large demand in the field of gynecologic medicine. However, the quality of the preparation is uneven in the market, so its clinical efficacy cannot be guaranteed. In order to improve and establish its quality control standard, high performance liquid chromatography (HPLC) was used to establish the fingerprint of Xinshenghua Keli. The detection was performed on Agilent 5 HC-C₁₈ (2) column(4.6 mm×250 mm, 5 microns) with methanol-0.1% formic acid solution as mobile phase for gradient elution, at a flow rate of 1 mL·min⁻¹ with column temperature of 25 °C. The injection volume was 10 μL and detection wavelength was set at the maximum value between 210.0 nm and 400.0 nm by Photo-Diode Array (PDA) detector. The fingerprint of 12 batches of high-quality Xinshenghua Keli was established and 43 common peaks were identified. The similarities of crowned products, 10 batches of ordinary ones made by Jiangsu Rongyu Pharmaceutical and 10 batches produced by different manufacturers were evaluated. The composition identification and source analysis for the common peaks were performed by comparing the retention time of herbal medicines and ultraviolet absorption spectrum, along with high performance liquid chromatography-mass spectrometry (HPLC-MS) technology. The established fingerprint of Xinshenghua Keli, has proven to have good precision, stability and repeatability through the methodology validation, so it can be used to comprehensively evaluate the quality of Xinshenghua Keli.
