Bariatric surgery began in 1950s.The rapid increase of obese patients and development of laparoseopic techniques lead to popularity of bariatric surgery all over the world in 1990s.Current mainstream of bariatric surgeries include laparoscopic adjustable gastric banding,sleeve gastrectomy,Roux-en-Y gastric bypass and biliopancreatic diversion.In this review,the efficacy of different surgical procedures was compared in the aspects of metabolic disorder remission and incidence of operation complications and mortality.Efficacy of bariatric surgery on the alleviation of metabolic disorders (including hypergycemia,hyperlipidemia,hypercholesterolemia),individual treatment and interdisciplinary cooperation should be emphasized.

Through the simulation based on a two-dimensional whole-heart electrophysiological model, the effect of ventricular electrical activity on the precordial cardioelectrical field as well as the ECG manifestation have been discussed. Such effect can vary with the changed excitation sequence of ventricles and the changed active and passive electrical properties of cardiac tissues. As the result, many abnormal ECG waves can form. By carefully analyzing such effect, the correlation among ECG waveforms recorded at different lead locations can be revealed and the significance of ECG manifestation can be fully explored.As a case of analyzing, some ECG waves at certain right chest lead locations can get a proper explanation.

Background Optic nerve crush (ONC) model is an available tool in the basic research on the mechanism and treatment of optic nerve injury.The opening optic nerves sheath crushing and via bulbar conjunctiva lateral canthus optic nerves crushing are frequently used ONC modeling methods.However,the comparison between these models is not elaborated.Objective This study was to compare the outcomes between opening sheath ONC model and via bulbar conjunctiva lateral canthus ONC model.Methods Twenty-four male SD rats were randomized into four groups.ONC models were established via superorbital rim opening sheath to crushing optic nerve for 20 seconds in the opening sheath ONC group,or via bulbar conjunctiva lateral canthus cutting to crush optic nerve for different time in the via bulbar conjunctiva ONC 20-second,40-second and 60-second groups,respectively.All models were monocular created in the rats,and the fellow eyes served as controls.In 14 days after modeling,flash visual evoked potential (F-VEP) were recorded,optic nerve and retinal sections were prepared in the rats.The histopathology of the samples was examined by hematoxylin and eosin staining.The expression of Brn-3α in the retinal ganglion cells (RGCs) was detected by immunofluorescence technique and the number of Brn-3α+ RGCs was counted.The modeling procedure and outcomes were compared between the two approaches.Results The latencies of P1 waves were significantly extended in the opening sheath ONC group,via bulbar conjunctiva ONC 20-second,40-second and 60-second groups in comparison with the corresponding control eyes (t =-11.64,-8.04,-6.50,-10.84,all at P＜0.01).The P1 latencies were longer in the opening sheath ONC group than those in the via bulbar conjunctiva ONC 20-second,40-second and 60-second groups (P =0.01,0.02,0.05),but no significant differences were found in the amplitudes of P1 waves between model eyes and corresponding control eyes (all at P＞0.05).The Brn-3α+ RGCs numbers were evidently decreased in the model eyes in comparison with the fellow control eyes.The Brn-3 α + RGCs numbers were (13.60 ± 2.14),(18.74 ± 3.61),(15.84 ± 2.31) and (14.58 ± 3.23)/field in the opening sheath ONC group,via bulbar conjunctiva ONC 20-second,40-second and 60-second groups,which reduced to 47.49％,67.70％,56.69％ and 50.17％ of the fellow eyes,respectively.No significant differences were seen in the Brn-3α+ RGC numbers between the opening sheath ONC group and via bulbar conjunctiva ONC 40-second or 60-second groups (both at P＞0.05).The disorder of glial cell arrangement,vacuolization of the cell matrix and infiltration of inflammatory cells were displayed in various model groups,with the prominent findings in the opening sheath ONC group.Conclusions Compared with the via bulbar conjunctiva ONC models,the morphological and functional damage of optic nerve is more obvious,and the survival rate of RGCs is lower in the opening sheath ONC models.

OBJECTIVE: To explore the expression and significance of programmed cell death 5 (PDCD5) and Bcelllymphoma/lewkmia-2(Bcl-2) in sinonasal squamous cell carcinoma (SNSCC). METHOD: Immunohistochemical method and Western Blot method was used to determine the expression of PDCD5 and Bcl-2 in specimen of SNSCC in thirty cases, sinonasal inverted papillomas (SNIP) in thirty-eight cases, and normal nasal mucosa in twenty cases. RESULT: (1) The expression of PDCD5 protein in SNSCC significantly decreased compared with SNIP and normal nasal mucosa. (2) The expression of Bcl-2 protein in SNSCC up-regulated obviously compared with SNIP and normal nasal mucosa. (3) Positive rate of PDCD5 protein and Bcl-2 protein in well, moderate and low differentiatied group is respectively 100.00%, 83.33%, 38.89% and 50.00%, 70.83% and 100.00%, the difference was statistically significant (P < 0.05). (4) In the follow-up cases, the survival rate of the patients with higher expression of PDCD5 protein was higher, but that with lower expression of Bcl-2 protein was higher. CONCLUSION The inactivation of PDCD5 protein and the activation of Bcl-2 protein may play an important role in the development of SNSCC, and there are a positive correlation between PDCD5 and Bcl-2 protein in SNSCC, which may be identified as a new therapeutic target.

Objective:To explore the efficacy and safety of Certolizumab pegol in patients with rheumatoid arthritis. Methods:Such databases as Pubmed, Medline, Embase, The Cochrane Library, WANFANG, CNKI, Science, CBM and VIP were searched from their establishment to March 2015 for collecting the randomized controlled trials comparing Certolizumab pegol and placebo in the treatment of RA. The meta-analysis was undertaken using RevMan5. 3 for Windows. Results:Ten publications and eight researches met the inclusion criteria with high quality. The results revealed CZP significantly improved the ACR20,ACR50,ACR70 response rates,and physical function. CZP was associated with a statistically significant reduction in Disease Activity Score in 28 joints-Erythrocyte sedimentation rate, arthritis pain, and fatigue. There were no significant differences of incidence of treatment-related adverse events between CZP group and placebo group. Conclusion:CZP significantly reduced the RA signs and symptoms,improved physical function and life quality as compared with the placebo in the treatment of RA. More large-scale RCTs are needed to evaluate the long-term efficacy and safety of CZP in the treatment of RA.

Toxoplasma gondii rhoptry proteins (ROPs) include dozens of proteins secreted by tachyzoites ,these ROPs are known to be critical for several processes such as invasion ,parasitophorous vacuole establishment ,proliferation ,egress and getting out of host immune protection .ROPs belong to the protein kinase family and have classic kinase domain ,however ,most of the members are designated as pseudokinases due to the lack of critical catalytic residues that are normally required for phos-phorylation of host signal molecules .Recent studies indicated that pseudokinases also have important functions ,such as regula-ting kinase activity by allosteric and promoting the interactions between proteins as scaffolds .In this paper ,we summarize the pseudokinases structural characteristics and some pseudokinases functions ,for the study of toxop lasma gondii and host interac-tion mechanisms ,molecular vaccines screening and drugs design .

Objective To analyze the curative effects of total knee arthroplasty(TKA)for severe genu varus combined with flexion deformity.Methods The clinical data of 25 patients(36 knees),who had undergone TKA for severe genu varus combined with flexion deformity from January 2005 to October 2010,were retrospectively analyzed.There were 7 males and 18 females,aged from 55 to 80 years(average 70.5 years).The primary diseases were osteoarthritis in 22 cases and rheumatoid arthritis in 3 cases.HSS knee score was used before and after the operation to assess the efficacy of the TKA.Results All of the patients were followed up for 4 to 9 years(average 6 years).The degree of flexion deformity was reduced from (21 ±63)°to(1.1 ±2.3)°;the degree of the varus decreased from(210 ±4.8)°to(175.6 ±2.1)°;range of motion of the knee joint increased from(70.5 ±20.5)°to(115.1 ±5.3)°;knee score augmen-ted from(33.2 ±10.5)to(90.7 ±8.5);function score added from(35.5 ±14.2)to(85.6 ±10.5);there were 21 cases(8 knees)rated as excellent,2(3 knees)as good and 2(3 knees)as fair,and the excel-lent and good rate was 86%.Most of the patients had normal force line of the knee joint,but 2 patients re-mained varus deformity of 5°~10°.Conclusion Satisfying outcome can be achieved by TKA in treating severe genu varus combined with flexion deformity of the knee.

This study was aimed to carry out pharmacological research on the hemostatic activity and mechanism of Yi medicine Ma-Bu (Paris polyphylla Smith var stenophylla Franch.). One kind of C27 steroidal saponin from P. polyphylla Smith var stenophylla Franch. was isolated and identified as Paris saponin H (PSH). The effect of PSH on the index of bleeding time (BT), prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen (FIB) of mice were measured. The results showed that PSH have significant hemostatic activity by shortening BT. The effect of PSH on shortening PT and APTT of mouse was not significant. However, the FIB was enhanced significantly after treatment with PSH. It was concluded that PSH had no significant promoting effect on the extrinsic coagulation pathway (ECP) or the intrinsic coagulation pathway (ICP). The enhancement of FIB may be a pathway for the effect of hemostatic activity by PSH.
