Objective To assess the effect of continuous renal replacement therapy (CRRT) on severe acute pancre-atitis (SAP). Methods According to the collaborative search strategy, MEDLINE (1966-2013.9), Embase(1974-2013.9), Chinese Wanfang database(1996-2013.9), CNKI(1979-2013.9) and the clinical control test database of Cochrane Library were searched.Published and unpublished literature and meeting summary were searched manually.Quality assessment and data extraction were conducted by two independent investigators. Meta-analysis was performed using RevMan 5.2. Results A total of 15 reports were identified which met the inclusion criteria, in which include data of 652 patients.Com-pared with control group, serum amylase decreased in CRRT group (WMD=-140.76, 95%CI was-212.42 to-69.11, P=0.000 1). Mediators of inflammatory mediators were scavenged effectively and APACHEⅡscore decreased in CRRT group (WMD=-2.97, 95%CI was-4.01 to-1.93, P<0.001). The overall survival rate was significantly higher in CRRT group than that in control group (RR=1.35, 95%CI 1.19-1.52, P<0.001). Conclusion Continuous renal replacement therapy could ef-fectively improve the survival rate of patients with severe acute pancreatitis.

Objective: To observe the effect of acupuncture plus thunder-fire moxibustion on the expressions of matrix metalloproteinase-3 (MMP-3), tissue inhibitor of metalloproteinase-1 (TIMP-1) and transforming growth factor-β1 (TGF-β1) in cartilage of knee osteoarthritis (KOA) rats, and to explore the mechanism of acupuncture plus thunder-fire moxibustion in the treatment of KOA. Methods:Thirty Sprague-Dawley (SD) rats were randomly divided into a blank control group, a model group and an acupuncture-moxibustion group by random digits table, 10 rats in each group. Rats in the model group and the acupuncture-moxibustion group were injected with papain in the right posterior knee joint to prepare the models. The levels of MMP-3 and TIMP-1 in rat synovium of each group were measured by enzyme-linked immunosorbent assay (ELISA) after 2 weeks of treatment. The level of TGF-β1 was determined by Motic B5 Micro-camera system. Results:The levels of MMP-3 and TIMP-1 in the cartilage of the model group were significantly higher than those in the blank control group (allP<0.01); the levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were lower than those in the model group, and the between-group differences were statistically significant (all P<0.05). The levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were higher than those in the blank control group, and the differences were statistically significant (all P<0.05). The level of TGF-β1 in cartilage tissues of the model group was significantly lower than that in the blank control group (P<0.01); the level of TGF-β1 in the acupuncture-moxibustion group was higher than that in the model group (P<0.05), but it was lower than that in the blank control group, and the between-group difference was statistically significant (P<0.05). Conclusion: Acupuncture plus thunder-fire moxibustion can effectively recover the abnormal expressions of MMP-3 and TIMP-1 in KOA model rats and somewhat up-regulate TGF-β1, which may be one of its mechanisms of acupuncture plus thunder-fire for KOA.

OBJECTIVETo investigate the effect of fragile histidine triad (FHIT) gene on the apoptosis of gastric cancer cells.

METHODSFHIT gene was transfected into gastric cancer cell line MGC-803 by liposome. Western blot and immunohistochemical assay were employed to detect the expression of FHIT. Apoptosis and cell cycle were analyzed by flow cytometry (FCM). Morphological changes were observed by light and electron microscope.

RESULTSStable expression of FHIT protein in transfected MGC-803 cells was obtained. The rates of G0/G1 phase and apoptosis cells were significantly higher in FHIT-transfected MGC-803 cells than those in control cells (64.4%compared with 49.5%and 32.0%compared with 12.2%, respectively).

CONCLUSIONThe results indicate that FHIT gene might be involved in the apoptosis of gastric cancer cells.

This study was aimed to investigate the relationship between Richter's syndrome (RS) transformation and clinical characteristics as well as karyotype of patient with chronic lymphocytic leukemia (CLL). By the follow-up of a patient with CLL, the clinical characteristics, karyotype, treatment pattern and its effect, as well as disease progression were monitored regularly with serological test, flow cytometry and FISH technique. The results indicated that the patient typically presented with history of CLL at initial diagnosis, with expression of CD5(+), CD19(+) and CD23(+), Binet stage C, as well as karyotype aberration of trisomy 12, and poorly responded to 4 cycles of standard chemotherapy of FCR regimen. The disease progression was confirmed at 5 months with the symptoms of fever in the absence of infection, elevated lactate dehydrogenase level and rapidly enlarging lymphnodes which showed typically diffuse large B cell lymphoma by the biopsy. It is concluded that karyotype aberration of trisomy 12 is one of the risk factors for RS transformation, and treatment pattern of the patient with CLL may be associated with the transformation of RS.

OBJECTIVETo systematically evaluate the effect and safety of Xuezhikang Capsule (XZKC) for adjuvant treatment for coronary heart disease (CHD) patients accompanied with or without dyslipidemia.

METHODSChina National Knowledge Infrastructure (CNKI) Database, Chongqing VIP Database (VIP), Wanfang Data base, Cochrane Library, and Medline (PubMed) were retrieved with the deadline of August 30, 2013. Randomized controlled trials (RCT) of XZKC in treating CHD patients with or without dyslipidemia were all included. Assessment of bias risk for included studies was conducted according to the Cochrane Handbook for Systematic Reviews of Intervention (Version 5.0.2): Criteria for judging risk of bias in the "risk of bias" assessment tool. Review Management (5.1.0) was employed for data statistics. If there was no significant heterogeneity, results from the random-effect model were presented. If the heterogeneity was not substantial, a meta-analysis was not performed and a narrative and qualitative summary was performed instead.

RESULTSA total of 28 RCTs (6,949 patients) were included after screening results. The methodological quality of included trial was generally lower. Results of Metaanalysis showed that XZKC was beneficial for CHD patients in decreasing cardiovascular events: when compared with the basic treatment group, the relative risk (RR) was 0.53 and 95% confidence interval (CI) was [0.35, 0.81]; when compared with the placebo + basic treatment group, RR was 0.52 and 95% CI was [0.42, 0.65]; when compared with the basic treatment group, RR for improving symptoms of angina was 1.20 and 95% CI was [1. 12, 1.30]; when compared with the basic treatment group, RR for improving abnormal ECG was 1.38 and 95% CI was [1.21, 1.57]. Thirteen studies showed that XZKC + basic treatment was obviously superior in lowering total cholesterol (TC) to that of the basic treatment group. Three studies showed that XZKC + basic treatment was obviously superior in lowering total cholesterol (TC) to that of the placebo + basic treatment group. Thirteen studies showed that XZKC + basic treatment was obviously superior in lowering low density lipoprotein cholesterol (LDL-C) to that of the basic treatment group. Three studies showed that XZKC + basic treatment was obviously superior in lowering LDL-C to that of the placebo + basic treatment group. A total of 18 studies describing adverse reactions (ADs) involved 61 ADs in the XZKC + basic treatment group. All suffered from mild symptoms or were improved after treatment. No severe ADs occurred.

CONCLUSIONTreatment of CHD by XZKC might lower the occurrence of cardiovascular events in CHD patients accompanied with or without dyslipidemia, relieve clinical symptoms, improve ECG, lower blood lipid levels, and with less adverse reactions.

This study was aimed to analyze the clinical and laboratorial characteristics of patients with chronic lymphocytic leukemia (CLL), as well as their relationship with outcomes of patients. The clinical and laboratorial data of 40 CLL patients admitted from 2004 to 2010 in our hospital were analyzed retrospectively. The results indicated that the most of CLL attacked the elderly male patients with median age 66 (from 42 to 80). Flow cytometric analysis showed that 25 cases were positive for typical immunophenotype of CLL. On the other hand, all the patients clearly expressed CD19 and CD5, 7 cases (17.5%) and 14 cases (35%) were positive for the expression of CD38 and Zap70 respectively. 8 cases harbored a mutated immunoglobulin heavy-chain (VH) gene, among them 4 cases belong to VH3 family. Interphase FISH analysis showed that P53 deletion, RB1 deletion, trisomy 12 and normal chromosome were detected in 6, 3, 1, and 5 cases, respectively. The median PFS in 31 patients received treatment of fludarabine based chemotherapy was 48 months (95%CI: 39 - 57 months), among them 27 cases (87.1%) achieved CR + PR. While PFS was 14 months (95%CI: 10 - 18 months, P < 0.001) in 9 patients received other treatment regimen, out of them only 3 cases (33.3%) achieved CR + PR. Patients with normal level of serum β2-microglobulin at diagnosis showed significantly higher overall survival (78%, 95%CI: 69% - 87%) in 36 months than those with abnormal level of serum β2-microglobulin (47%, 95%CI: 35% - 59%, P = 0.004). Significant difference in the rate of CR + PR was noted in the Zap70 positive group (50%) and in negative group (88.5%, P = 0.006). All of 8 patients with IgVH mutation displayed CR after treatment, while 4 cases (66.7%) archived CR among 6 patients without IgVH mutation. It is concluded that CLL is characterized by high heterogeneity in both clinical features and molecular markers, which are associated with prediction of outcomes for patients. The treatment with fludarabine-based chemotherapy results in a major benefit and long survival for patients with CLL.

OBJECTIVE: To explore the correlation between the interleukin-17 (IL-17) level of peripheral blood and aggression of bipolar mania. METHODS: Thirty-six patients of bipolar mania were selected as experimental group by DSM-IV-TR and received treatment with quetiapine and lithium. Thirty-six healthy volunteers with similar age and gender were selected as control group. The level of IL-17 at baseline in each group and the level of IL-17 in the experimental group after treatment for 2, 4 and 8 weeks were detected by ELISA. RESULTS: The level of IL-17 in experimental group at baseline, after treatment for 2 and 4 weeks were all significantly higher than that in control group. After 8 weeks treatment, there was no significant difference between the two groups (P > 0.05). After 2, 4 and 8 weeks treatment, the total score and aggression score of Young Mania Rating Score (YMRS) were significantly lower than the baseline level (P < 0.05). In experimental group, the level of IL-17 was positively correlated with the two scores of YMRS at baseline (P < 0.05). CONCLUSION Bipolar mania may be related to the up-regulation of IL-17. The level of IL-17 is related to the severity of manic symptoms at baseline, especially aggression symptom.

OBJECTIVETo compare clinical results of treating Neer two- and three-part of proximal humeral fractures between anterolateral acromial approach and deltopectoral approach.

METHODSFrom January 2009 to December 2012, 49 patients with Neer two- and three-part of proximal humeral fractures were treated with locked plate fixation. In anterolateral acromial approach group, there were 22 patients including 9 males and 13 females with an average of (63.2±7.6) years old, while 27 patients in deltopectoral approach including 12 males and 15 females with an average of (62.9±7.0) years old. Operative time, blood loss during operation, fracture healing time and complications were observed and compared, postoperative Constant-Murley scoring and VAS scoring were applied for evaluate function of shoulder joint and pain at 3 months, 1 and 2 years respectively.

RESULTSAll patients were followed up from 24 to 41 months with an average of 34.5 months. Operative time, blood loss, fracture healing time in anterolateral acromial approach group was (68.20±7.04) min, (151.30±20.57) ml, (10.88±4.90) weeks respectively, and better than that of in deltopectoral approach group which was (75.81±13.70) min, (242.10±37.25) ml and (13.60±2.45) weeks. Three months after operation, Constant-Murley scoring and VAS score in anterolateral acromial approach group was 88.32±5.45, 0.41±0.63 and better that of in deltopectoral approach group which was 63.53±8.31, 1.65±1.02. There was no significant differences between two groups in Constant-Murley scoring and VAS score at 1 and 2 years after operation. Each group has one case occurred loss of length humerus head height, and there was 1 case with subacromial impingement, 1 case with bolt loose and 2 cases with delayed union in deltopectoral approach. No axillary nerve injury, humeral head necrosis and breakage of internal fixation occurred both of two groups.

CONCLUSIONBoth of anterolateral acromial approach and deltopectoral approach are effective in treating Neer two- and three-part of proximal humeral fractures, and can obtain excellent outcomes. Moreover, anterolateral acromial approach has advantage of less trauma, less blood loss, shorter operative time, rapid recovery of shoulder joint function and fracture.

AIMTo explore whether the oligonucleotide uptake in hematological tumor cells is related to cellular species and proliferation.

METHODSIntracellular mean fluorescence intensity was measured by flow cytometry.

RESULTSAfter treatment with FITC-labeled G3139 at the concentration of 0.60 mumol.L-1 for 4 h, the G3139 uptake into peripheral blood mononuclear cell and bone marrow mononuclear cell in hematological tumor patients was significantly higher than that in normal control. There was different uptake of G3139 among the malignant hematological tumor cell strains, and the uptake in cells derived from monocyte, B lymphocyte and myeloid cell was much higher than that in cells derived from T lymphocyte. After treatment with all-trans retinoic acid (ATRA), HL60 cell proliferation was markedly inhibited and the uptake of G3139 decreased significantly.

CONCLUSIONHematological tumor cells were capable of taking up oligonucleotide, and the oligonucleotide uptake in hematological tumor cells is related to its cellular species and its activation.

To investigate the reversal effect of reduced glutathione (GSH) on suppression of NK cells by reactive oxygen metabolites (ROM) in K562 cells, interleukin-2 (IL-2) or mononuclear cell (Mo) was added in cultured cell line of K562 cells and NK cells, the yield of ROM and K562 cell suppression rate were observed. Then the histamine dihydrochloride (DHT) or GSH was added in the mixed cultured cell lines, the ROM production and K562 cell suppression rate were observed. The results showed that the ROM yield increased from 33.17 +/- 5.08 U/L to 223.59 +/- 9.41 U/L by IL-2, and K562 cell suppression rate increased from 65.56% to 85.89% by IL-2 (P < 0.01). The ROM yields were 389.79 +/- 43.83 U/ml, 456.74 +/- 42.77 U/ml and 601.42 +/- 21.92 U/ml respectively, and K562 cell suppression rates were 82.36%, 81.36% and 48.09% respectively, when Mo was added in the mixed cultured cell lines under ratios of E/Mo being 10/2, 10/5 and 10/10. When E/Mo was 10/2, DHT or GSH was added in the mixed cultured cell line ROM yield decreased from 389.79 +/- 3.83 U/L to 50.21 +/- 2.4 U/L or -3.58 +/- 9.49 U/L (P < 0.05) respectively. With increase of concentration of DHT or GSH, the ROM yield in the mixed cultured cell line decreased (P < 0.05), the K562 cell suppression rate increased from 82.53% to 94.64% or 96.39% (P < 0.05), the more ROM yield, the less K562 suppression rate (P < 0.05). When E/Mo is 10/5 or 10/10, the ROM yield decreased by the high concentration of DHT or GSH (P < 0.05), but the K562 cell suppression rate not increased by every concentration of DHT or GSH. GSH was as effective as DHT in the reversing ROM and increasing K562 cell suppression rate. It is concluded that GSH may reverse ROM and increase K562 cell suppression rate, and GSH is as effective as DHT, but GSH has less side-effect than DHT. Therefore, GSH would be better antileukemia immune adjuvant.
