Objective To analyze the impacts of early enteral nutrition (EN) and parenteral nutrition (PN) on the prognosis of acute pancreatitis.Method By searching relevant literature between January 1996 and August 2013 in Chinese and English databases including Wanfang,VIP,CNKI,PubMed,the Cochrane Library,CBM,and EMABSE,we compared the prognosis of acute pancreatitis after EN or PN in terms of casefatality rate,infections,multiple organ failure,and other complications.Result Compared with PN,early EN significantly reduced the case-fatality rate [OR =0.37,95％ CI (0.23,0.58),P ＜ 0.000 1],decreased the infection rate [OR =0.24,95％ CI (0.15,0.39),P ＜0.000 01],shortened hospital stay [MD =-9.87,95％ CI (-10.84,-8.89),P ＜ 0.000 01],and reduced complications [OR =0.26,95％ CI (0.12,0.58),P =0.001 0] in patients with acute pancreatitis,although the incident of multi-organ failure showed no significant difference [OR =0.35,95％ CI (0.10,1.19),P =0.09].Conclusions For patients with acute pancreatitis,early EN is superior than PN in terms of case-fatality rate,infection rate,hospital stay,and complications.Therefore,it should be applied in such patients whenever condition allows.

Twenty-seven patients with subclinical hyperthyroidism(SH)complicated by paroxysmal atrial fibrillation(PAF)were treated with methimazole plus bisoprolol.All patients were examined by Doppler echocardiogram and 24 h ambulatory electrocardiograms before and 3 months after treatment.Serum FT3,FT4,and TSH levels were measured with RIA.The results showed that low-dose methimazole therapy could improve the left ventricular diastolic function(P < 0.01)and help maintain sinus rhythm.The incidence of subclinical hypothyroidism was low.Low-dose methimazole was effective and safe in patients with SH complicated by PAF.

Aim To investigate the expression of mGluR1 in hippocampus of spontaneously epileptic rats(SER) by control study.Methods Total RNA was extracted from hippocampus of SER and Wistar rats,and mGluR1 mRNA expression was detected by RT-PCR;the expression of mGluR1 protein was detected by immunohistochemistry and Western blot.Results mGluR1 mRNA of SER was lower than that of Wistar rats in hippocampus(P0.05) were found.In positive cells,mGluR1 proteins were enhanced.By Western blot,total mGluR1 protein was down-regulated in SER hippocampus(P

Objective To analyze the treatment and prognosis of patients with gestational trophoblastic neoplasia with urinary system and adrenal glands metastasis.Methods The treatment and prognoses of 32 patients with gestational trophoblastic neoplasia with urinary system and adrenal glands metastasis from Dec.1990 to Dec.2010 at Peking Union Medical College Hospital,Chinese Academy of Medical Sciences were respectively reviewed.Results Treatment methods:all 32 patients received 9 courses(in average) of a multi-drug chemotherapy in our hospital (range 1-24 coures).Among them,3 patients with bladder metastasis received intravesical chemotherapy of fluorouracil.9 patients received surgical treatments in other hospital and 15 patients received surgical treatments while undergoing chemotherapy in our hospital.Treatment results:after the treatments,of the 32 patients,21 (66％) patients achieved complete remission,3(9％) exhibited partial remission and 8 (25％) progressed.Seven patients with renal metastasis achieved complete remission.Two patients with adrenal glands metastasis achieved complete remission.Nine patients with urinary bladder metastasis achieved complete remission.Seven patients with ureters metastasis achieved complete remission.Two (10％) of 21 patients with complete remission relapsed.Conclusions Multidrug and muhiroute chemotherapy is the main strategy for patients with gestational trophoblastic neoplasia with urinary system and adrenal glands metastasis.The prognoses of patients with renal or adrenal glands metastasis are much worse than those in patients with bladder and ureters metastasis because of concomitant multiogran metastasis.Adequate attention should be given to patients with renal or adrenal glands metastasis.Individual treatment,assisted by surgery when necessary,may be carried out for these patients to achieve a better outcome.

As an important synthetic antibacterial drug, sulfonamides play an important role in the anti-infection field. Based on the research and development status of sulfonamides, this paper broke the classical structure of sulfanilamide, and designed and synthesized a series of acetyl-contained sulfanilamide tertiary amine thiol azole compounds and sulfanilamide tertiary amine amino azole compounds. The structures were confirmed by ¹H NMR, ¹³C NMR and HRMS. The antimicrobial activity of synthesized compounds in vitro was tested. The antimicrobial activity of amino triazole compound 7a gave stronger activity against Pseudomonas aeruginosa than that of positive control drug norfloxacin, and its inhibitory activity against Staphylococcus aureus was close to that of norfloxacin. The interaction between compound 7a and calf thymus DNA was studied, and the docking experiment between this compound and DNA was also researched.

To analyze the composition regularity of prescriptions containing Scutellaria baicalensis in Drug Standard of Ministry of Public Health of the Peoples Republic of China--Chinese Patent Medicines and Preparations on the basis of the traditional Chinese medicine inheritance support system (TCMISS), in order to provide reference for new drug R&D. the platform's software V2.0 was applied to establish a database of prescriptions containing S. baicalensis. The software's statistical statement module, association rules and improved mutual information method and other data mining technologies were adopted to analyze commonly used drugs, combination rules and core combination of S. baicalensis prescriptions. Having analyzed 477 prescriptions containing S. baicalensis, the researchers summarized 45 most commonly used drug combinations, whose ingredients mostly had functions of heat-clearing and damp-drying, purging fire for removing toxin and hemostasis. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. There were 23 diseases that S. baicalensis were most frequently applied in the treatment. Having compared three highly frequent diseases--cold, cough and dizziness, the researchers concluded that S. baicalensis could show different therapeutic effects through different combination ratios. Therefore, TCMISS (V2.0) is an important tool in analyzing the composition regularity of traditional Chinese medicines. The longitudinal and parallel comparison method is an effective method for studying the clinical composition regularity of S. baicalensis, while providing reference for new drug R&D.

OBJECTIVETo study the effect of Modified Dachengqi Decoction (MDD) as whole course therapy on mediators of inflammation in severe acute pancreatitis (SAP) model rats, and to compare interventional advantages over intestinal mucosal barrier (IMB) of SAP rats between whole course therapy of MDD and early stage therapy of MDD.

METHODSTotally 190 SD rats were divided into five groups according to random digit table, i.e., the sham-operation group, the model group, the octreotide (OT) group, the early stage MDD treatment group, the whole course MDD treatment group, 38 in each group. SAP models were established with retrograde injection of 5% sodium taurocholate into the pancreaticobiliary duct. Three hours after modeling normal saline (NS) was administered to rats in the sham-operation group and the model group by gastrogavage, once per 12 h.1.35 µg/100 g OT was subcutaneously injected to rats in the OT group, once every 8 h. 0.4 mL/100 g MDD was administered to rats in the early stage MDD treatment group, and 6 h later changed to NS (once per 12 h).0.4 mL/100 g MDD was administered to rats in the whole course MDD treatment group, once every 12 h. The accumulative survival rate and morphological manifestations of pancreas and small intestine were observed under microscope 48 h after modeling. Pathologic scores of the pancreas and small intestine were conducted at 4, 6, 24, and 48 h after modeling. Contents of serum amylase (AMY), alanine transaminase (ALT), and TNF-α were also detected. The expression of high mobility group box protein 1 (HMGB1) in the small intestine tissue was also detected by Western blot. The positive rate of bacterial translocation in mesenteric lymph nodes (MLNs) was observed within 48 h. Correlations between serum TNF-α or HMGB1 in small intestinal tissue and pathological scores of the pancreas or the small intestine were analyzed.

RESULTSThe accumulative survival rate was 100. 0% in the sham-operation group, 79. 2% in the whole course MDD treatment group, 70. 8% in the OT group, 45. 8% in the early stage MDD treatment group, and 37.5% in the model group. At 6 h after modeling, pathological scores decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). At 24 and 48 h after modeling, pathological scores of the pancreas and the small intestine decreased more in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group (P <0. 05). At 6, 24, and 48 h after modeling, serum contents of AMY and ALT both decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). At 48 h after modeling serum contents of AMY and ALT both decreased more in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group (P < 0.05). At 6 h after modeling serum TNF-α levels decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). At 6, 24, and 48 h after modeling the level of HMGB1 in the small intestinal tissue decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). Of them, HMGB1 levels at 24 and 48 h were lower in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group (P < 0.05). The number of MLNs bacterial translocation at 48 h after modeling was lower in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group and the model group (P < 0.05). Serum TNF-α contents within 6 h were positively correlated with pathological scores of pancreas (r = 0.579, P < 0.01). ROC curve showed that serum TNF-α contents could predict the severity of SAP (ROC = 0.990, 95% Cl: 0.971 to 1.000). HMGB1 in the small intestine was positively correlated with pathological scores of the small intestine (r = 0.620, P < 0.01).

CONCLUSIONSEarly stage use of MDD could effectively reduce the release of TNF-α, while whole course use of MDD could effectively inhibit the expression of HMGB1. The latter could preferably attenuate injuries of the pancreas and the small intestine, lower MLNs bacterial translocation, and elevate the survival rate.

Objective To elucidate the protein expression and gene expression status and the relationship between epidermal growth factor receptor (EGFR) protein expression and EGFR gene status.Methods Tissue microarray containing 72 cervical squamous cell carcinoma tissues was constructed,and EGFR protein expression and gene status were evaluated by immunohistochemical and fluorescence in situ hybridization (FISH) techniques.Results Protein expression of EGFR:69 of 72 cervical squamous cell carcinomas were observed.The results demonstrated it was significant association with invasion depth,lymphnode metastasis and lymph-vessel invasion (x2 =4.998,P ＜ 0.05 ; x2 =4.299,P ＜ 0.05 ; x2 =4.686,P ＜ 0.05) in cervical squamous cell carcinomas.For FISH assessing EGFR gene,64 of 72 carcinomas were observed; 7 of 64 cases showed EGFR gene amplification,and 25 disomy,23 trisomy and 9 polysomy were detected.There were high levels of protein expression in all the EGFR gene amplification cases,and there were significant association between EGFR protein expression and the gene copy number (x2 =13.564,P ＜ 0.05).Conclusions EGFR may participate in the occurrence,progression and metastasis of cervical squamous cell carcinoma.Overexpression of EGFR protein may result from gene amplification and gene copy number increases,which showed that EGFR gene expression status may be a more effective biological indicator of cervical squamous cell carcinoma targeted therapy.

Objective:To investigate the expression levels of PPARα/γin RAW264. 7 cells in the early stages of co-cultivation with Echinococcus granulosus in vitro. Methods:RAW264. 7 cells were co-cultured with E. granulosus and collected at 12,24,36,48, 72 h. The mRNA levels of PPAR-γ,PPAR-α,M1 macrophages-associated cytokines including TNF-α,MCP-1 and IL-1β,and M2 mac-rophages-associated cytokines including Arg-1,TGF-β and Fizz-1 were detected by qRT-PCR. The protein levels of Arg-1 and MR were analyzed by ELISA. Results:The expression levels of PPAR-γ, PPAR-αand the M2 macrophages-associated cytokines including Arg-1,TGF-β,Fizz-1 and MR were significantly increased,especially at 72 h (P<0. 05). M1 macrophages-associated cytokines including TNF-α,MCP-1 and IL-1β were decreased at 72h although increased at first. Conclusion:During the early stages of co-cultivation with Echinococcus granulosus in vitro, the levels of PPAR-γ/α are up-regulated in RAW264. 7 cells, which may drive macrophage polarization and play a role in the immune escape.

ObjectiveTo investigate the effects of sleep deprivation on expressions of Mir-132,mir-134 in the different regions of rat brain.MethodsAll the male SD rats were divided into control group ( normal sleep group),sleep deprivation (SD).The modified multiple platform method (MMPM) was used to establish sleep deprivation model.Mir-132,mir-134 level was detected by real time PCR.ResultsMir-132 were significantly increased in SD groups in hippocampus compared with the control groups ( 51.87 ± 8.13 vs 67.25 ± 7.59 ) (P ＜0.01 ).Mir-134 were significantly decreased in SD groups compared with the control groups( 1.82 ±0.15 vs 1.45± 0.12 )(P ＜ 0.01 ).There were no statistically significant differences in cortex and thalamus (P ＞ 0.05 ).Cortex mir-132 level in SD group and control group was 1.57 ±0.10,1.48 ±0.11 respectively,and it was 1.37 ±0.09,1.36 ±0.11 in thalamus;Cortex mir-134 level in SD group and control group was 98.26 ± 5.17,100.80 ±4.15respectively,and it was 97.56 ± 6.28,91.01 ± 4.07 in thalamus.ConclusionThe upregulation of mir-132 and downregulation of mir-134 implies that two miRNAs did opposite actions in the processes of sleep deprivation.This findings indicate that hippocampus mir-132,mir-134 levels in the SD rat may reflect associated depressive patho-physiological processes.
