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.

Objective To investigate the clinical features and pathogenic genes of a familial hypokalemic periodic paralysis ( HOKPP).Methods PCR amplification and DNA sequencing were used to screen candidate genes of the HOKPP family members (CACNA1S, SCN4A, KCNE3), and the clinical features were carefully analyzed at the same time.Results The sequencing analyses of the SCN4A gene in the proband identified three nucleotide sequence mutations, which influenced the amino acid sequence of the skeletal sodium channel.One of the mutations was identified as a C/T heterozygous pattern at the 2111th nucleotide position in exon 13, resulting in a change from Thr to Met at the 704th amino acid position of the sodium channel protein.All affected patients carried the Thr704Met mutation, whereas unaffected family members did not.Clinical symptoms in this family followed an autosomal dominant inheritance pattern.Muscles weakness, pain and hypokalemia in the period between attacks were seen in all patients.Paralytic symptoms occurred early, lasted longer and recurred frequently, while cold was the main predisposing factor.With the progress of the disease, patients represented persistent weakness and atrophy in proximal muscles.Conclusions Mutation (Thr704Met) in the SCN4A gene should be responsible for this family.This mutation causes severe HOKPP and progressive muscle atrophy.

Objective To investigate the effects of TLR7 on imiquimod induced apoptosis of THP-1 derived macrophages.Methods Three cell lines ( THP-1 derived macrophages, MDCK cell line and HUVEC cell line) with different capabilities of expressing TLR7 were selected.The survival rates of cells af-ter the treatment with different concentrations of imiquimod were detected by MTT assay.The levels of IL-6 in the supernatants of TLR7 inhibitor chloroquine or TLR7-siRNA treated cells were detected by enzyme-linked immunosorbent assay.The apoptosis of cells was detected by flow cytometry after inhibiting the ex-pression of TLR7.Results Imiquimod induced the apoptosis of THP-1 derived macrophages, MDCK cell lines and HUVEC cell lines.The levels of IL-6 were significantly decreased as the expression of TLR7 was inhibited by treating THP-1 derived macrophages with chloroquine or TLR7-siRNA.Treating THP-1 derived macrophages with chloroquine or TLR7-siRNA did not affect the cell apoptosis induced by imiquimod.Con-clusion Imiquimod could induce the apoptosis of THP-1 derived macrophages through TLR7 independent pathway.

AIM: To study the effects of 7 weeks prolonged haevy load swimming and Panaxadiol Saponins (PDS) on the expression of ?-actin in quadriceps muscle of thigh in rats. METHODS: After 7 weeks prolonged heavy load swimming training, the expression of ?-actin in quadriceps muscle of thigh was quantitatively examined by Northern blotting analysis in the condition with or without PDS treatment. RESULTS: The expression of ?-actin in rat quadriceps muscle of thigh in exercise+PDS group was significantly higher than that in sedentray control group and exercise+saline group at 24 th hour after intensive training. No statistical difference between exercise+androsan group and exercise+saline group was observed.CONCLUSION: PDS enhanced ?-actin expression in quadriceps muscle of thigh in rats.

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.
