This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

BACKGROUND:At present, the internal fixation and fusion surgical treatment of lumbar degenerative disease tends to diversify, but posterior lumbar interbody fusion within a single bilateral pedicle screw fixation is stil common in clinical practice; the two ways after treatment can achieve satisfactory clinical efficacy, but which way has advantages is stil controversial. OBJECTIVE:To evaluate the efficacy and safety of unilateral and bilateral pedicle screw fixation and single segment lumbar interbody fusion in the repair of lumbar degenerative disease by a meta-analysis system. METHODS: According to the Cochrane Colaboration search strategy, we searched MEDLINE, PubMed, EMBASE, CBMdisc, CNKI, VIP and WanFang Data. Randomized controled trials concerned unilateral and bilateral pedicle screw fixation and single segment lumbar interbody fusion in the treatment of lumbar degenerative diseases. By two reviewers, in strict accordance with inclusion and exclusion criteria, literatures were screened, data were extracted, and the methodology quality of included trials was criticaly assessed. RevMan5.1 software was used for meta-analysis. RESULTS AND CONCLUSION: Six randomized controled trials involving 507 patients were included. The results of meta-analysis showed that fixed unilateral and bilateral pedicle screw between single lumbar fusion and surgery in the treatment of lumbar degenerative diseases, significant differences were detected in surgical time [WMD=-40.29, 95% CI (-43.79, -36.79)], intraoperative blood loss [WMD=-74.13, 95%CI (-86.13,-62.13)], length of hospital stay [WMD=-1.04, 95%CI (-1.30,-0.79)], final folow-up Visual Analogue Scale score [WMD=0.33, 95% CI (0.24, 0.42)], final folow-up Oswestry dysfunction index [WMD=-1.07, 95%CI(-1.57, -0.56)]; unilateral side was better than bilateral side (P < 0.000 1). There was no significant difference in complication rate [RR=0.54, 95% CI(0.25, 1.17)] and fusion rate [RR=0.53, 95%CI (0.22, 1.28)] (P=0.12 andP=0.16). These results suggested that unilateral and bilateral pedicle screw fixation and single lumbar fusion in the treatment of lumbar degenerative disease has achieved satisfactory results. Unilateral pedicle screw fixation can reduce operation time, intraoperative blood loss and length of stay. Visual Analogue Scale score and Oswestry dysfunction index improved significantly in a short period after treatment.

Objective To observe clinical efficacy and explore clinical value of a modified procedure of double-stapling technique for mid-low rectal cancer.Methods Clinical data of patients undergoing laparoscopic anterior resection at the Department of General Surgery,the First Affiliated Hospital of Soochow University from February 2011 to February 2015 was analyzed retrospectively.According to the different ways in doing double-stapling technique,we divided patients into modified group (51 cases) and conventional group (74 cases).Parameters were compared between the two groups as general considerations,oncologic outcomes.Data were analyzed by SPSS 17.0 software packet,using t and x2 inspection.Results The difference of the general data of two groups was not statistically significant (P ＞ 0.05).Operation time in the modified group was longer than that of the conventional group [(169 ± 23) vs.(150 ±42)min,t =-3.150,P ＜0.05],but it had shorter drainage tube indwelling days [(7.9 ±2.9)d vs.(10.8±11.6)d,t=1.999,P＜0.05] and length of hospital stay after surgery [(10.0±3.6)d vs.(13.3 ± 13.7) d,t =1.025,P ＜ 0.05].The incidence of anastomotic leakage (2.0％ vs.18.9％,x2 =4.402,P ＜ 0.05) and tenesmus(3.9％ vs.17.6％,x2 =4.110,P ＜ 0.05) in the modified group was less than that of the conventional group.The difference in those areas was not statistically significant (P ＞ 0.05),such as intraopretive blood loss,per-anal exhaust time,consumption of liquid diet time,anastomotic bleeding,intestinal obstruction,reoperation for neostomy and infections.Conclusions Compared with traditional laparoscopic anterior resection,End-Corner anastomosis has the benefits of less postoperative anastomotic leakage and fewer low anterior resection syndrome.

Background and purpose:Anastomotic leakage and low anterior resection syndrome(LARS) are both common complications in dual-anastomosis for patients with low rectal cancer. The aim of this study was to observe and explore the signiifcance and role of vertical cutting of the closed distal rectum in dual-anastomosis for patients with low rectal cancer.Methods:A total number of 120 patients with mid-low rectal cancer who admitted to and completed laparoscopic rectal cancer resection in the Department of General Surgery, the First Afifliated Hospital of Soochow University from Feb. 2010 to Jun. 2014 were pair-matched into Groups A and B based on their gender,age, tumor size, the distance of lower edge to the dentate line and tumor staging, etc. For the 55 patients in Group A (observation group), the rectum distal end was closed vertically instead of horizontally while disposing “the ifrst intestinal anastomosis”, intestine-intestine anastomosis was conducted in an “end-corner” approach when dealing with “the second intestinal anastomosis”, upper corner (“dog ear”) of the closed line in the distal end of the rectum was removed, the lower corner (“dog ear”) of the closed line in the distal end of the rectum was removed using vascular occlusion clamp method, and the T-shaped interchanges (“dangerous triangle”) of stapled sutures formed after anastomosis were strengthened with absorbable suture. For the 65 patients in Group B (control group), laparoscopic dual anastomosis was conducted using conventional method, and the two “dog-ears” and “dangerous triangles” were kept without any treatment. The clinical outcomes of the two groups of patients were analyzed retrospectively. Results:In group A, It was convenient to complete the operation when the “dog ears” and “dangerous triangle” on the vertical line after cutting the closed distal rectum vertically by “end-corner” anastomosis. The axis of intestine formed a certain angle making the closed distal rectum into “ampulla” sample without “dog ears”. the “dangerous triangle” were strengthened with absorbable suture. In group B, The distal and proximal intestine located on the same axis after intestine-intestine anastomosis leaving two “dog ears” and a “dangerous triangle”. The general clinical data of patients in the two groups were comparable and not signiifcantly different (P>0.05). The two groups of patients showed no signiifcant differences in blood loss, postoperative drainage, postoperative anastomotic bleeding, anal exhaust time, and length of hospital stay (P>0.05). However, the operation time as well as the numbers of anastomotic ifstula occurrence, defecation, tenesmus and post-operation re-ostomy differed significantly (P<0.05).Conclusion:Vertical cutting of the closed distal rectum with dual anastomosis made the “new” intestine closer to the physiological bending and morphology of the rectum, meanwhile, it simpliifed the approach of removing “dog ear” and strengthening “dangerous triangle”, ifnally it signiifcantly reduced the incidence of post-surgical complications.

OBJECTIVETo explore a new procedure of laparoscopic dual anastomosis for mid-low rectal cancer to reduce postoperative complications.

METHODSClinical data of 56 patients with mid-low rectal cancer undergoing laparoscopic rectal cancer resection(modified double-stapling technique, MDST, modification group) in the Department of General Surgery, the First Affiliated Hospital of Soochow University from February 2010 to June 2014 were compared with the data of 64 patients with mid-low rectal cancer (conventional double-stapling technique, DST, convention group) in the same period based on gender, age, tumor size, the distance from lower edge to the dentate line and tumor staging, etc. Patients in the modification group received operation as follows: (1) the rectum distal end was closed vertically instead of horizontally. (2) the anastomosis was conducted in an "end-corner" approach. (3) upper corner of the closed line in the distal end of rectum was removed. (4) the lower corner of closed line in the distal end of rectum was removed using vascular occlusion clamp method. (5) two T-shaped interchanges ("dangerous triangle") of stapled sutures formed after anastomosis were strengthened with absorbable suture. Patients in the convention group received laparoscopic dual anastomosis using conventional method: two corners and "dangerous triangles" were kept without any treatment. The clinical outcomes of two groups were analyzed retrospectively.

RESULTSThe intraoperational blood loss, postoperative drainage volume, postoperative anastomotic stoma bleeding, bowel function return and hospital stay were not significantly different between the two groups (all P>0.05). As compared to the convention group, the modification group had longer operation time [(211 ± 91) min vs. (174 ± 57) min, P<0.05], lower incidence of postoperative anastomotic leakage [1.8%(1/56) vs. 12.5% (8/64), P=0.030], lower tenesmus rate [3.6% (2/56) vs. 14.1% (9/64), P<0.05], less postoperative stoma re-creation [0 vs. 9.4% (6/64), P<0.05].

CONCLUSIONModified laparoscopic dual anastomosis for mid-low rectal cancer can significantly reduce the incidence of post-surgical complications such as anastomotic leakage.

Objective To explore the clinical value of neurography and nerve root sealing in treatment of multilevel lumbar spinal stenosis with lumbar instability using Endo-P/TLIF.Methods A total of 60 patients with multi-segment lumbar spinal stenosis and lumbar instability hospitalized in our hospital were included in this study From January 1,2022 to June 21,2022.All patients underwent nerve root closure angiography before surgery to confirm the responsible segments,and then the responsible segments were treated with Endo-P/TLIF.The patients were followed up for 6 months.The basic information on the age,gender,course of disease,surgical time,intraop-erative bleeding,hospitalization time,and off-bed ambulation time was collected.Then the data on VAS score,ODI score,JOA score,lumbar lordosis angle,intervertebral height,dural cross-sectional area,sacral inclination angle,pelvic projection angle,and pelvic inclination angle before,right after,3 months and 6 months after the operation were calculated.The number of responsible segments indicated by MRI and confirmed by nerve root closure angiography and the number of the single segment,double segments,3 segments,and above finally decompressed were statisti-cally analyzed.Results All patients went through the surgery safely.During the 6-month follow-up,one patient did not return to the hospital for consultation on time,and one patient was out of contact.Finally,the follow-up data of 58 patients were completely collected for statistical analysis.Fifty-five cases were remarkably improved,2 better,and 1 moderately,6 months after the operation,with a total effectiveness rate of 100%.The number of unilateral and bilateral single responsible segments confirmed by nerve root angiography and sealing was significantly larger than by MRI(P<0.05),but the number of unilateral and unilateral double,or multiple responsible segments was signifi-cantly smaller(P<0.05).There were statistically significant differences in terms of postoperative VAS score,ODI score,JOA score,VAS score,ODI score,JOA score,lumbar lordosis angle,intervertebral height,dural cross-sectional area,sacral inclination angle,pelvic inclination angle as compared to the preoperative data(P＜0.05).The pelvic projection angle was insignificantly improved as compared to the preoperative condition(P ? 0.05).Conclusion The accurate diagnosis with selective neurography and nerve root sealing improves the confirmation of responsible nerve segments before operation.Base on the accurate diagnosis,multi-segment lumbar spinal canal stenosis with lumbar instability can be effectively treated with Endo-P/TLIF,the responsible segment decompressed,trauma and bleeding reduced,hospital stay shortened,spinal physiological curvature well recovered,and clinical efficacy improved.Therefore,the method is worthy of extensive application in clinical practice.

Informatization plays an important role in the management of clinical diagnosis and treatment. However, due to the specialty of the discipline, the informatization construction of critical care medicine(CCM)is faced with such problems as the inefficient application of data, the low compliance of diagnosis and treatment operation, and the lack of intelligent quality control tools. The authors discussed the new mode of CCM information management based on data driven. By upgrading clinical information system, establishing single disease control system, introducing comprehensive intelligent analysis platform and building open remote platform, the bottleneck of CCM informatization was broken. The information collection and interaction in ICU was realized, the automatic monitoring and early warning of diagnosis and treatment process was realized, the operation of medical staff according to the guidelines was effectively improved, and the ability of diagnosis and treatment and management efficiency was improved.Furthermore, the homogenization of regional critical medical information could be promoted.
