Objective To systematically evaluate the efficacy of the lienal polypeptide injection combined with chemotherapy or radiotherapy on the short-term efficacy, Karnofsky score, immune function and adverse reactions in treatment of various cancers. Methods The databases of PubMed, Embase, Cochrane Library, CNKI, Wanfang and VIP were retrieved from database establishing time to January 2017, and the randomized controlled trials (RCT) about lienal polypeptide injection combined with radiotherapy or chemotherapy in the treatment of advanced cancer were collected. The quality assessment was conducted and eligible trials were included in the Meta-analysis. Results A total of 23 articles were included, involving 1658 patients. The patients were divided into treatment group (lienal polypeptide injection combined with chemotherapy or radiotherapy, 842 cases) and control group (chemotherapy or radiotherapy alone, 816 cases). Results of Meta-analysis showed that the short-term effective rate (RR = 1.20, 95％ CI 1.07-1.33, P = 0.001), the improvement rate of Karnofsky score (RR = 1.77, 95％ CI 1.43-2.19, P < 0.05) and immune function related indicators: CD3+ (MD = 9.48, 95％ CI 6.76-12.20, P < 0.01), CD4+ (MD = 7.54, 95％ CI 5.38-9.71, P < 0.01), NK cells (MD = 4.47, 95％CI 3.45-5.48, P < 0.01) and CD4 +/CD8 + (MD = 0.33, 95％ CI 0.25-0.42, P < 0.01) in the treatment group were significantly higher than those in the control group, and the differences were statistically significant. The incidence of nausea and vomiting (RR = 0.51, 95％ CI 0.35-0.73, P = 0.0002) and bone marrow suppression (RR = 0.41, 95％ CI 0.25, 0.68, P = 0.0006) in the treatment group were significantly lower than those in the control group, and the differences were statisticallysignificant. There was no statistical difference in CD8+ level and the incidence of neurotoxicity, diarrhea, oral mucositis and hepatic injury between the two groups (all P > 0.05). Conclusion Lienal polypeptide injection combined with radiotherapy or chemotherapy is superior to conventional radiotherapy or chemotherapy alone in the treatment of cancer, which can improve the quality of life of patients with tumors, reduce the incidence of nausea and vomiting and bone marrow suppression induced by the treatment.

Aim To investigate the effect of MTX(included(±)MTX,(+)MTX and(-)MTX)on the proliferation of ECV304 cells and to explore its mechanisms.Methods ECV304 cells were cultured.The cell proliferation was determined by MTT.The morphological changes were inspected by inverted microscope.Cell cycle phases were assayed by propidium iodide staining flow cytometry.Results ECV304 cells were treated with(+)MTX,(-)MTX and(±)MTX at 1～150 μmol·L~(-1) for 24,48,72 h.The results showed that the proliferation of ECV304 cells was significantly inhibited under different conditions.The order of the inhibited efficacy was(+)MTX>(±)MTX>(-)MTX.The morphology of ECV304 cells were changed by(+)MTX,(-)MTX and(±)MTX treatment,which included the cell shrinkage,chromatin condensation.After administration of 10 μmol·L~(-1) of(+)MTX,(-)MTX and(±)MTX for 48 h,the cell cycle phases were assayed by propidium iodide staining flow cytometry.The result showed DNA replication was interfered by(+)MTX,(-)MTX and(±)MTX treatment.Conclusions The proliferation of ECV304 cells has the chiral selective effects by(+)MTX and(-)MTX treatment,and the inhibition on ECV304 cells proliferation of(+)MTX is significantly stronger than that of (-)MTX.

For patients with DTC,the side effect of 131I therapy on fertility and offspring is an important issue since genital tissues are highly sensitive to radiation.Exposure to 131 I radiation may result in transient impairment of gonadal function in male patients caused by elevated levels of serum follicle stimulating hormone and luteinizing hormone,low sperm count and motility.In female patients,exposure to 131I radiation may be complicated with delay of menstruation,oligomenorrhea and transient cessation of menstrual period.Most of these symptoms may resolve within one year after 131 I therapy.A slightly earlier menopause is the only reported long-term side effect of 131I therapy on ovarian function.Currently available data do not indicate that exposure to 131I may cause permanent infertility in male patients with DTC.For female patients with DTC,131 I therapy does not affect fertility or pregnancy outcomes beyond one year.

Objective To evaluate whether small endoscopic sphincterotomy (EST) plus balloon dilation (EPBD) can replace endoscopic sphincterotomy (EST) alone for patients with common bile duct (CBD) stones.Methods From May 2008 to April 2011,462 patients with CBD stones were randomly divided into two groups.The success rate of complete stone removal after the first session,the rate of using mechanical lithotripsy (ML),the short-term complications,the procedure time and fluo roscopy time were compared between the two groups.Results Overall ductal clearance did not differ between the two groups (96.5％ vs 93.5％,P＞0.05).The complication rates at 24 hours were 6.9％ for the small EST plus EPBD group and 11.7％ for the EST group (P＞0.05).However,the rate of complete stone removal after the first session using small EST plus EPBD was significantly higher than EST alone (86.2％ vs 70.4％,P＜0.05).ML was required significantly more often in the EST group when compared with the small EST plus EPBD group (34.8％ vs 12.1％,P＜0.05).The total procedure time and total fluoroscopy time in the small EST plus EPBD group were significantly shorter than the EST group [(38.6±15.5) min vs (47.1±20.2) min,P＜0.05 and (17.3± 7.0) min vs (26.5±10.8) min,P＜0.05].Conclusions Compared with EST,small EST plus EPBD was safe and more efficacious for bile duct stones.In the future,small EST plus EPBD probably can replace EST to be the first treatment of choice for bile duct stones.

Objective To evaluate the efficacy and safety of small endoscopic sphincterotomy (EST) plus large balloon dilataion (EPLBD) for removal of common bile duct (CBD) stones larger than 12mm.Methods From June 2009 to December 2011,a total of 198 patients with CBD stones were randomly divided into two groups to receive EPLBD (n =100) or EST only (n =98).The rate of complete stone removal after the first session,the overall success rate of stone removal,the rate of using mechanical lithotripsy (ML),the rate of post procedure complication,procedure time and fluoroscopy time were compared between the two groups.Results The rate of complete stone removal after the first session in EPLBD group (89.0％) was significantly higher than that in EST group (71.4％,P ＜ 0.05).ML was required significantly more often in EST group (35.7％) compared to EPLBD group (12.0％,P ＜0.05).Total procedure time and total fluoroscopy time in EPLBD group (39.3 ± 15.8 min and 14.2 ±5.2 min) were significantly shorter than those of EST group (48.4 ± 19.3 min and 24.2 ±9.4 min,P ＜0.05).There was no significant difference between two groups in overall success rate of stone removal (97.0％ in EPLBD vs.93.9％in EST group,P ＞ 0.05) and the complications rate (8.0％ in EPLBD vs.13.3％ in ESTgroup,P ＞0.05).Conclusion EPLBD is as safe and effective as EST for common bile duct stones,larger than 12mm,and is more efficient in terms of procedure time,use of ML and success rate of stone removal.

Objective To investigate the efficacy of prophylactic pancreatic stent placement and nonsteroidal antiinflammatory drugs( NSAIDs) for the prevention of post?endoscopic retrograde cholangiopan?creatography(ERCP) pancreatitis(PEP). Methods A total of 623 patients with high risk factors for PEP were treated with prophylactic pancreatic stent placement ( 145 patients, group A) or rectal NSAIDs( 478 pa?tients, group B) for PEP prevention by using the propensity score matching( PSM) analysis. Incidence of PEP, moderate and severe PEP were investigated. According to risk factors of PEP, indications of prophy?lactic pancreatic stent placement were analysed. Results Of 623 patients with high risk factors, 145 pairs were generated after PSM.Pancreatitis occurred in 32 patients,10 (6?9%) in group A and 22 (15?2%) in group B( P<0?05 ) . Moderate?to?severe pancreatitis developed in 5 ( 3?4%) patients in group A and 14 (9?7%) patients in group B(P<0?05).Risk factors of post?ERCP PEP were cannulation attempts duration longer than 10 minutes, precut sphincterotomy, more than one pancreatic guidewire passages and history of ampullectomy. Conclusion Although the NSAIDs represent an easy, inexpensive treatment, prophylactic pancreatic stent placement is still a better prevention strategy for PEP.Prophylactic pancreatic stents should be recommended to those with risk factors including cannulation attempts duration longer than 10 minutes, precut sphincterotomy, more than one pancreatic guidewire passages and ampullectomy.

Objective To evaluate the efficiency of transcatheter closure of secundum artrial septal defect (ASD) using Amplatzer occluder device in 5 years.Methods There were 18 children with ASD.Each ASD was occluded using Amplatzer occluder device through the percutaneous procedure.The closure procedure was guided by fluoroscopy and transthoracic echocardiography.All patients were followed up by physical examination,color flow echocardiography,chest radition,electrocardiography at 48 h,1month,3 month,6 month,one year,two years,three years,four years and five years.Results Cardiac murmur disappeared or lightened.Arrhythmia and right heart volume in all patients were improved after the procedure.A case revealed a trival shunt of short duration and vanished after one month color flow echo.A case has “spring′s beat” in heart when she goes to bed in three years after the procedure.Another patient had serious headach after closure and recoved after heparin therapy.Conclusions Transcatheter closure of secundum ASD using amplatzer occluder device is safe and efficient by follow-up.In order to prevent cerebral embolism,heparin should be injected in vein in two days.

Objective: To observe the clinical efficacy of tuina manipulations in treating different types of tic disorders (TD). Methods: Eligible TD patients were classified into three types, transient tic disorders (TTD), chronic multiple tic disorders (CMTD) and Tourette syndrome (TS), according to their disease duration and severity. The three types of children were treated with the same tuina manipulations. Changes in the Yale global tic severity scale (YGTSS) score, effective rate for tic, and cervical spine imaging examination results (including asymmetry of the lateral atlanto-dental interval, broadened anterior atlanto-dental interval, C2 spinous process deviation, occipito-atlanto-axial flexion/ extension instability) were observed after 1-month and 3-month treatments respectively. Results: The YGTSS score changed significantly after 1-month and 3-month treatments compared with that before treatment (both P<0.01); the effective rate for TD was 46.6％ and 86.7％ respectively after 1-month and 3-month treatments; there were significant differences comparing the effective rate for tic between different types of TD after 1-month and 3-month treatments (all P<0.05); comparing the effective rate for tic after 1-month treatment with that after 3-month treatment for the same type, the intra-group differences were statistically significant [TTD group (P<0.01), CMTD group (P<0.01), TS group (P<0.05)]; the abnormal parameter rates in neck imaging examination after 3-month treatment were significantly different from those before treatment (all P<0.01). Conclusion: Tuina manipulation is effective for TTD, CMTD and TS. It can correct the abnormal alterations of patients' cervical vertebrae, and its efficacy for TTD is most significant.

OBJECTIVETo investigate the expression of uncoupling protein (UCP)-2, 3 mRNA in skeletal muscle of the scalded rats after escharectomy at different post scalding stages.

METHODSOne hundred and twenty Wistar rats were employed in the study, in which 8 served as normal control (C) and 112 were subjected to 30% TBSA 3rd degree scalding and then again, divided into 4 groups. The rats in A group were sacrificed on 8th, 24th, 96th, 120th and 168th post scalding hours (PSHs) without escharectomy. The rats in B group underwent escharectomy at 8 PSH, and those in C group underwent escharectomy at 24 PSH. All the rats in both groups were sacrificed on 96, 120 and 168 PSHs after escharectomy, Escharectomy was performed at 96 PSH in rats of D group, and they were sacrificed on 120 and 168 PSHs after escharectomy. The serum levels of leptin and TNFalpha, and the expression level of UCP2 mRNA were determined at all time points in all groups of rats.

RESULTS(1) The serum levels of leptin in A group were obviously lower than that in C group (P < 0.01) during 24 approximately 168 PSHs, while those in B, C and D groups were much higher than those in A group (P < 0.01) during 24 approximately 168 PSH. (2) The serum TNFalpha levels in A group at all time points were higher than that in control group, while that in B group at all time points were lower than that in A group (P < 0.05 or 0.01), and that in C group at 168 PSH was lower than that in A group (P < 0.05). (3) The UCP2 mRNA expression in skeletal muscle in A group was increased evidently since 8 PSH (P < 0.01), peaking at 24 PSH and lowering thereafter, while that in B and C groups at 168PSH was significantly lower than that in A group at the same time points (0.32 and 0.35 vs 0.71, P < 0.05). The trend of the change in UCP3 mRNA expression in skeletal muscle was similar to that of UCP2.

CONCLUSIONThe postburn up-regulation of UCP mRNA expression might play important roles in the increase of metabolic rate. Escharectomy during shock stage could lower down the expression of UCP2 and UCP3 mRNA expression, and it could be beneficial by lowering metabolic rate.
