Objective To study the effect of monosialoteterahexosyl ganglioside (GM1) on neurobehavioral development in premature infants with white matter damage. Methods A total of 636premature infants who were hospitalized in NICU of two hospitals from Jan 2005 to May 2009 received routine bedside cranial sonography detection before 1 week-aged. Forty premature infants were diagnosed as being premature white matter damage and divided into the treatment group (20 cases ) and the control group (20 cases) randomly. The cases in the treatment group accepted GM1 20 mg additional to 5% glucose solutionthe iv drip, one time per day,for a cycle of 14 d. 1 -3 cycles were given in accordance with patient's condition. Other treatments were same to the control group. All cases were evaluated by neonatal behavioral and neurological assessment (NBNA) at the rectified age of 40 gestational weeks and by Children's Developmental Center of China (CDCC) test at 3 months-aged and 12 months-aged. Results The NBNA scores of the treatment group (38.10±0.91) were significantly higher than the control group (36.10±1.59) at the rectified age of 40 gestational weeks (P＜0.01). The indexes of mental development(MDI) and psychomotor performance development (PDI) by the CDCC tests in the treating group (3 months-aged MDI:91.66±6.38;PDI:87.11±5.57; 12 months-aged MDI:104.10±6.45; PDI:100.46±3.87) were significantly higher than those in the control group (3 months-aged MDI:81.07±0.72; PDI:81.90±6.70; 12 months-aged MDI:98.45±8.57; PDI:95.91±6.59) at 3 months-aged and 12 months-aged ( P ＜ 0. 05 ). Conclusion GM1 can accelerate the neurobehavioral development in premature infants with white matter damage.

Objective To unravel the relationship between artefiM blood lactate (ABL) level and is1et β-cell secretion constituents in stress hyperglycemia(SHG)setting of critical illness,and analyze the effect of inadequate tissue perfusion on islet β-cell function.Method According to ABL level,68 critically ill patients with SHG were divided into three groups,namely,group A(ABL≤1.5 mmol/L),group B (ABL 1.6～4.4 mmol/L)and group C(ABL≥4.5 mmol/L).Another 25 healthy volunteers served as insulin (IRI) were measured.The homeostasis model assessment for secretion index of islet beta-cell (HOMA-β)was calculated.The relationship among the above B-c3eH secretion constituents were analyzed.Results The TI level of group C was significantly lower than that of group A(P<0.01).The PI levels of group B and C were significantly higher than those of group A and control group(P<0.05).The C-P level of group C was significantly higher that of group A and control group(P<0.05).The HOMA-β of group C was significant lower than that of group A and B and control group(P<0.05).The ABL had positive correlation with PI and C-P(r=O.322,P=O.015;r=0.513,P=0.000),and the ABL had negative correlation with TI and HOMA-β(r=-0.353,P=0.007;r=-0.294,P=0.002).Conclusions The worse tissue perfusion was in SHG of critical illness,the higher PI and C-P were,the lower TI was, Inadequate tissue perfusion setting could lead to islet beta-cell paracrisis and deceleration.

Objective To study the effect and mechanism of Plantago depressa Willd. extract on rats with chronic nonbacterial prostatitis. Methods Sixty rats were divided into six groups randomly: normal control group, model control group, cernilton group, high-, medium- and low- dose Plantago depressa Willd. extract group, ten rats in each group. Chronic nonbacterial prostatitis rat model was established in the animals except of normal control group. Rats in the cernilton group were administrated with cernilton solution( 100 mg . kg-1 ) . High, middle and low dose Plantago depressa Willd. extract groups were given 150, 300 and 600 mg . kg-1 of Plantago depressa Willd. extract, respectively. The rats in the normal control and model control group were treated with the same volume of purified water.The administration was performed once every day, and lasted for three weeks.Effects of Plantago depressa Willd.extract on prostate index (PI), prostate specific antigen (PSA), tumor necrosis factorα ( TNF-α) , interleukin-1β ( IL-1β) , cycloxygenase 2 ( COX-2) , prostaglandin E2( PEG2 ) , transforming growth factor-β1( TGF-β1 ) , and connective tissue growth factor ( CTGF ) levels and pathological changes of prostate tissue in rats were observed. Results PI and PSA levels of the normal control group were(0.8±0.3)mg.g-1 and(106.5±10.6)pg.mL-1, respectively;those of the model control group were(2.2±0.2)mg.g-1 and(319.4±23.4)pg.mL-1 respectively;Those of the cernilton group were(1.6±0.3)mg.g-1 and(179.5±13.7)pg.mL-1 respectively;Those of the low-, medium- and high- dose Plantago depressa Willd.extract groups were(1.8±0.4),(1.3±0.3),(0.8±0.3)mg.g-1 and(263.4±28.6),(178.5±21.5), (143.5±12.9)pg.mL-1, respectively.Compared with the model control group, PI and PSA were significantly decreased(P<0.01) , TNF-α, IL-1β, COX-2, PEG2 , TGF-β1 and CTGF levels in the prostate tissues were decreased ( P<0. 01 ) , and inflammatory cell infiltration and fibrosis of prostate tissue was significantly alleviated in the model control group. Conclusion This study confirms Plantago depressa Willd.extract exerts effective therapeutical effect on chronic nonbacterial prostatitis in rats.

Objective To analyze the outcome of allograft function of the HBsAg(+) recipients and discuss the suitable time of antiviral therapy. Methods Twenty-one HBsAg(+) recipients were randomly divided two groups: one group (11 cases) taking lamivudine orally after recovery of intestinal function, and another group (10 cases) taking lamivudine orally when liver dysfunction and increased HBV-DNA (HBV-DNA>106 copies/L) occurred during the period of follow-up. Liver function, allograft function, and hepatitis virus reactivation were followed up for 2 years after transplantation. Results Hepatitis recurrence and liver dysfunction after renal transplantation lay in viral replication after immuno-suppression. Lamivudine therapy accomplished the goals of viral suppression, and normalization of alanine aminotransferase (ALT) levels. Preemptive lamivudine therapy for recipients had a better liver and allograft function than oral administration for patients with liver dysfunction and increased HBV-DNA copies during a period of the two-years follow-up. Conclusion HBsAg (+) is not contraindication of renal transplantation. Preemptive lamivudine therapy early after operation could avoid liver dysfunction and improve the renal allograft function during the period of two-years follow-up.

The diagnosis and treatment of multiple myeloma (MM) have make remarkable progress, which were reviewed in the 57th American Society of Hematology (ASH) annual meeting. In this annual meeting, the effects of advanced proteasome inhibitor (PI), antibody, checkpoint blockade, immunomodulatory agent (IMiD), histone deacetylase (HDACI) and chimeric antigen receptor T-cell (CAR-T), and new diagnostic technologies were reported. The real point is to apply the best available diagnosis and therapy at this meeting. At present, regardless of advances, all of randomized clinical trials push to combined agents, and combined with hematopoietic stem cell transplantation, efficacy will be improved in further. So some professors also refered to 2015 year as 'the advance year of MM'.

AIM: To study the clinical treatments and prognosis of the severe pneumonia in 12 patients after renal transplantation. METHODS: Twelve patients with severe pneumonia following renal transplantation treated in Guangdong Provincial Hospital of Traditional Chinese Medicine were selected between May 2004 and October 2006. They all agreed to the experiment. Seven patients had pneumonia at 3 months after transplantation, 1 at 3.5 months, 3 at 4 months and 1 at 5 months. The main therapy included immunosuppressive removal at early stage, mask oxygen inhalation, bi-level airway pressure ventilation or tracheal intubation to correct the hypoxemia; the algogen was detected by many approaches, and specific treatment was carried out according to the susceptibility test; gastroenteric nutrition was supplied through nasogastric tube, and part patients were given parenteral nutrition to strengthen nutrition support. Imaging examination of lung and blood gas analysis were performed every two to three days to evaluate the curative effect; transplanted kidney function was detected to determine the acute rejection early. RESULTS: All 12 patients were involved in the result analysis without any lost. Etiological agent detection: There were three cases with fungal pneumonia, 4 with cytomegalovirus pneumonia, 3 with bacterial pneumonia, 1 with mixed infection and 2 with unclear agent. Two cases of cytomegalovirus pneumonia developed rapidly into acute respiratory distress in 1 week after hospitalization and finally died of respiratory failure; the rest 10 patients were rescued successfully, except one with pulmonary interstital fibrosis, which could affect the life quality. CONCLUSION: The key points of successful treatment for severe pneumonia are the combination of early aggressive reduction of the immunosuppressive therapy, early detection of responsible pathogen and effective control of severe hypoxemia.

Methods: The serum soluble ICAM-1(sICAM-1) and E-selectin(sE-selectin) and tumor necrosis factor-?(TNF-?) from 45 exacerbated COPD patients,35 stable patients and 30 healthy as controls were measured by double antibody sandwich quantitative enzyme linked immunosoebent assay(ELISA). Results: The levels of both sICAM-1 and sE-selectin in the exacerbated group were significantly higher than those in the control(P

Objective To study the protective effects of colquhounia root tablet against oleic acid-induced acute lung injury (ALI) .Methods Forty-eight healthy Wistar rats weighing 200-250 g were randomly divided into 3 groups: ALI group ( n = 18) ; colquhounia root tablet group ( n = 18) and control group ( n = 12) . The animals were anesthetized with intraperitoneal 2% pentobarbital. ALI was induced by intravenous injection of oleic acid 0.04 ml?kg-1. In colquhounia root group colquhounia root tablet 300 mg?kg-1 was instilled into the stomach twice a day for 10 days before Ⅳ oleic acid injection. In control group normal saline 0.04 ml?kg-1 was given Ⅳ instead of oleic acid. The animals were killed 4h after intravenous oleic acid. Blood was collected from left ventricle immediately before the animals were killed for determination of expression of CD11a, CD11b and CD18 in neutrophils, monocytes and lymphocytes by flow cytometry using monoclonal antibodies. The lungs were immediately removed and left lung was lavaged via left main bronchus. Broncho-alveolar lavage fluid (HALF) was collected, WBC count in BALF and the percentage of active neutrophils were determined. Lung permeability index (BALF protein concentration/plasma protein concentration) was calculated. Results The expression of CD11la, CD11b and CD18 in neutrophils and monocytes, the lung permeability index, the WBC count and percentage of active neutrophils in BALF were significantly higher in ALI group than in control group. Colquhounia root tablet pretreatment significantly attenuated the changes induced by Ⅳ oleic acid. Conclusion Colquhounia root tablet pretreatment can effectively protect the animals from oleic acid induced ALI by downregulation of the expression of CD11a / CD18 and CD11b / CD18 in WBC.

Objective:To investigate the serum endothelial cell specific molecule-1 (ESM-1) level and its clinical significance in patients with hypertensive disorders complicating pregnancy (HDCP).Methods:Three hundred pregnant women with HDCP (HDCP group) and 300 pregnant women undergoing health check-ups (healthy control group) from January to December 2019 in Maternity and Child Health Hospital of Wenling City of Zhejiang Province were selected. In HDCP group, hypertension during pregnancy was in 94 cases, mild preeclampsia was in 131 cases, and severe preeclampsia was in 75 cases. The serum ESM-1, serum uric acid and 24-hour urine protein levels were detected. The incidences of neonatal asphyxia, fetal distress, cesarean section, polyhydramnios, premature rupture of membranes and postpartum hemorrhage in the HDCP group were recorded.Results:The serum ESM-1, serum uric acid and 24-hour urine protein in HDCP group were significantly higher than those in healthy control group: (0.42 ± 0.05) μg/L vs. (0.33 ± 0.04) μg/L, (262.34 ± 23.18) mmol/L vs. (212.37 ± 22.16) mmol/L and (0.36 ± 0.07) g vs. (0.11 ± 0.03) g, and the differences were statistical significant ( P<0.01). The correlation analysis results showed that the serum ESM-1 was positive correlation with serum uric acid and 24-hour urine protein in HDCP pregnant women ( r = 0.497 and 0.512, P<0.01). The serum ESM-1 in pregnant women with mild preeclampsia and severe preeclampsia were significantly higher than that in pregnant women with hypertension during pregnancy: (0.44 ± 0.05) and (0.51 ± 0.06) μg/L vs. (0.38 ± 0.04) μg/L, the serum ESM-1 in pregnant women with severe preeclampsia was significantly higher than that in pregnant women with mild preeclampsia, and the differences were statistical significant ( P<0.05). With the median serum ESM-1 (0.41 μg/L) as the boundary, pregnant women with HDCP were divided into high ESM-1 group (154 cases) and low ESM-1 group (146 cases). The incidences of neonatal asphyxia, fetal distress, cesarean section, polyhydramnios, premature rupture of membranes and postpartum hemorrhage in high ESM-1 group were significantly higher than those in low ESM-1 group: 14.94% (23/154) vs. 6.16% (9/146), 26.62% (41/154) vs. 9.59% (14/146), 46.10% (71/154) vs. 29.45% (43/146), 25.32% (39/154) vs. 3.42% (5/146), 23.38% (36/154) vs. 4.11% (6/146) and 20.13% (31/154) vs. 7.53% (11/146), and the differences were statistical significant ( P<0.01). Conclusions:Serum ESM-1 level is elevated in pregnant women with HDCP . Serum ESM-1 level is closely related to the severity of HDCP and pregnancy outcomes.
