Anastomotic leakage is one of the most serious complications following colorectal surgery. Occurrence of anastomotic leakage is concealed and numerous risk factors might relate to anastomotic leakage, which greatly affect the postoperative outcomes and life quality of patients. Therefore, it is necessary to recognize risk factors to predict anastomotic leakage in advance and adopt available treatments to reduce the incidence. This review summarized the risk factors of postoperative anastomotic leakage base on two aspects, and so on. Perioperative related factors and biological markers, aiming to provide a theory for predicting anastomotic leakage then improving the treatment outcomes of colorectal cancer patients .

ObjectiveTo study the efficacy of transcatheter arterial chemoembolization (TACE) after liver resection for hepatocellular carcinoma (HCC) with tumor thrombus in the main trunk and/or first branch of portal vein,and to clarify prognostic factors affecting survival.Methods From 2005 to 2009,there were 358 consecutive patients with HCC who underwent surgical resection in our Department.In 55 patients (15 ％),portal vein tumor thrombus (PVTT) was found intraoperatively or postoperatively during histopathological examinations to involve the first portal branch,main portal trunk,or contralateral portal branch.In this retrospective study,these 55 patients were divided into two groups:Group A,29 patients received postoperative TACE,and Group B,26 patients who did not receive TACE.The clinical data and survivals were compared between the two groups.Prognostic factors were indentified using univariate analysis,followed by multivariate regression analysis using the Cox proportional hazards model.ResultsThere were no significant differences in the demographic clinical data between Group A and Group B.The overall 1-,2- and 3-year survivals for the 55 patients were 63.3 ％,51.4 ％ and 43.5 ％,respectively.The accumulative 1-,2- and 3-year survivals for group A were 71.4 ％,60.1 ％ and 50.1 ％,respectively.The corresponding figures for group B were 56.7％,21.7％ and 10.4％,respectively.Multiple tumors,intrahepatic metastases,hepatic vein thrombus,and invasive type of tumor thrombus were found to be risk factors for short-term survival on univariate analysis,while the latter 3 factors were further found to be significant prognostic factors in the Cox proportional hazards model.Postoperative TACE was shown to be a significant factor in both univariate and multivariate analyses.ConclusionLiver resection was beneficial for some patients with portal vein tumor thrombus.Postoperative TACE further improved the prognosis and prolonged survivals in these patients.

Objective To evaluate the efficacy and safety of two forms of preparations of dexamethasone palmitate in the treatment of rheumatoid arthritis (RA).Methods A multicenter,double-blind,randomized,parallel-group clinical trial was carried out according to good clinical practice (GCP).A total of 237cases of RA patients with mild to moderate knee swelling were randomly divided into the treatment group (n=118 ) or the control group (n=119) and were treated with two kinds of dexamethasone palmitate 8 mg injection respectively.The primary efficacy endpoints were the circumference of the knee joint at the upper and the lower edge after the intra-articular injection.The secondary efficacy endpoints were joint tenderness index and patients general assessment.The adveme events were recorded.Analysis of covariance,t test or Wilcoxon test,x2 test or Fisher exact test were used for statistical analysis.Results The upper edges of the treatment group and the control group after treatment were (37.2±3.3) cm and (36.4±3.9) cm respectively,and the lower edges of the two groups were (34.4±2.9) cm and (33.9±3.4) cm respectively.They were all significantly smaller than the edges before treatment [(38.1± 3.3) cm and (37.3±4.0) cm of the upper edges,(35.1±3.0)cm and (34.6±3.6) cm of the lower edges respectively ) (P＜0.O1)].After treatment,the joint tenderness index were improved (P＜0.01).A total ratio of great improvement and improvement of patients general assessment of the two group patients were 67.5％ (79/117) and 74.8％ (86/115) respectively.No statistical significant difference was found in all primary and secondary efficacy endpoints between the two groups (P＞0.05).During the clinical trial,the incidence of adverse events related to the treatment of two groups were 4.2％ and 6.8％,without any significant difference (P＞0.05).Conclusion New preparation of dexamethasone palmitate has the same efficacy and safety as the imported producted in the treatment of RA.The circumference of the knee joints at the upper and the lower edge may be used to assess the effects of intra-articular injections.

AIM:To explore the therapeutic effect of a novel Rho kinase inhibitor WAR 5 on the experimental autoimmune encephalomyelitis (EAE) and its possible mechanism.METHODS: Female C57BL/6 mice were randomly divided into EAE group and WAR5 group.EAE model was induced by the application of MOG 35-55 peptide.WAR5 was in-jected intraperitoneally every other day from post-immunization (PI) day 3 to PI day 27.The clinical score and body weight were recorded every other day .On PI day 28, the animals were sacrificed and spinal cords were obtained for HE and mye-lin staining .The splenocytes were isolated and the expression of CD 16/32 and CD206 were analyzed by flow cytometry . The protein extracts from the brains and spinal cords were collected for the measurement of inducible nitric oxide synthase ( iNOS) by Western blotting .RESULTS:The administration of WAR 5 delayed the onset of EAE and attenuated the clini-cal symptoms .The results of the pathological examination revealed that WAR 5 inhibited the infiltration of inflammatory cells and improved myelination in spinal cords , accompanied with the poralization of M 1 macrophages to M2 phenotype in the spleen.WAR5 inhibited the expression of iNOS in the central nervous system , especially in the spinal cords .CON-CLUSION:The therapeutic effect of WAR5 on EAE may be related to the shift of M1 macrophages to M2 phenotype and inhibition of inflammation in the central nerve system .

Objective To explore the effect of low-carbohydrate/high-monounsaturated fatty acids (LC/HMD) nutrition program for patients with diabetes mellitus and stroke. Methods Thirty-seven patients with diabetes mellitus and stroke after percutaneous endoscopic gastrostomy (PEG) were enrolled in this study, and these patients were treated with liquid food nutritional support. All patients were given high-carbohydrate (HCD) nutritional support at the first and second day and then changed to LC/HMD nutrition program. The blood glucose fluctuations were monitored by continuous glucose monitoring(CGM) system. Meanwhile the daily dose of insulin injections, glycosylated hemoglobin (HbA1c) and biochemical indicators were detected. for just admission and just give LC after/HMD nutrition program and three months later on HbA1c and blood biochemical indexes were detected. Results 3 months after LC/HMD nutrition program treatment, the levels of mean amplitude of plasma glucose excursions (MAGE), ratio of hyperglycemia to time, ratio of glycopenia to time, HbA1c, daily dose of insulin injections were significantly improved compared with those at the 2nd of LC/HMD nutrition program treatment and with HCD nutritional support (P < 0.05). Three months after LC/HMD nutrition program treatment, the levels of blood biochemistry index had no significant change (P > 0.05). Three months after LC/HMD nutrition program treatment, the blood glucose fluctuations significantly reduced in all patients. Conclusions For patients with diabetes mellitus and stroke and receiving liquid food treament, LC/HMD nutrition program can significantly improve glycemic index, reduce dependence on insulin, and lower blood sugar fluctuations.

OBJECTIVETo investigate the value and safety of the surgery with vascular resection and reconstruction during pancreatectomy for pancreatic cancer.

METHODSThe clinical data of 206 patients with pancreatic cancer who underwent radical resection were retrospectively analyzed from January 2009 to March 2014 in Lihuili Hospital, Medical center of Ningbo.All cases were divided into non-vascular resection group(132 cases), the combined vein resection group(66 cases) and the combined arterial resection group(8 cases). The peri-operation data, the incidence of postoperative complications and the survival were compared in pairs among three groups.All patients were followed up till September 2014.

RESULTSThere were no statistical differences for the preoperative data among three groups.The operation time and the blood loss (M(QR)) were (347±96)minutes and (500(400)) ml in non-vascular resection group, (425±91)minutes and (800(500))ml in combined vein resection group, (508±120)minutes and (1 750(2 075))ml in combined arterial resection group, with significant differences among three groups(all P<0.01). The incidence of postoperative complication was 16.7%(22/132) in non-vascular resection group, 28.8%(19/66) in combined vein resection group, and 6 cases in combined arterial resection group, respectively.There were significant differences between non-vascular resection group and combined vein resection group(P<0.05), non-vascular resection group and combined arterial resection group(P<0.05), as well as between combined vein resection group and combined arterial resection group(P<0.05). The median survival time was 15 months for non-vascular resection group, 15 months for combined vein resection group, and 12 months for combined arterial resection group.No significant difference was found among three groups(all P>0.05). The postoperative mortality was nil for all of groups.

CONCLUSIONSCompared with non-vascular resection, combined vein resection can be performed safely with a similar prognosis. The surgery of combined arterial resection could only be justified when R0 resection for pancreatic cancer could be achieved for highly selected patients.

Objective:To analyze the application value of color Doppler ultrasound,microribonucleic acid-19a(miR-19a)and miR-210 in carotid artery stenosis.Methods:A total of 102 patients with carotid artery stenosis who were diagnosed and treated in Cangzhou People's Hospital from October 2020 to October 2022 were selected as the research group,and 102 health persons who underwent color Doppler ultrasound of physical examination in hospital at the same period were selected as the health control group.Both two groups underwent color Doppler ultrasound examination and digital subtraction angiography(DSA)within one week after admitted to hospital.The miR-19a and miR-210 between the two groups were compared,and the miR-19a and miR-210 of patients with different stenosis degrees of research group also were compared.And then,the diagnostic values of color Doppler,miR-19a,miR-210 and the combination of them were analyzed in diagnosing carotid artery stenosis.Results:The results of color Doppler ultrasound in detecting common carotid artery 102 patients of research group indicated that 15 cases were normal,and 15 cases occurred mild stenosis,and 21 cases occurred moderate stenosis,and 21 cases occurred severe stenosis and 33 cases occurred complete occlusion.The miR-19a of the research group was significantly higher than that of the health control group,and the miR-210 of the research group was significantly lower than that of the health control group(t=10.755,-5.903,P<0.05).The miR-19a results of the research group indicated that the miR-19a of mild stenosisthat of moderate stenosis>severe stenosis>complete occlusion,and the differences were statistical significant(F=160.399,147.462,P<0.05),respectively.The receiver operating characteristic(ROC)curve analysis showed that the area under curve(AUC)values of color Doppler ultrasound,miR-19a,miR-210 and combined diagnosis of them for carotid artery stenosis were respectively 0.892,0.842,0.729 and 0.978,and the sensitivity and specificity of the combined diagnosis were respectively 97.1%and 95.1%.Conclusion:The combined diagnosis of color Doppler ultrasound,miR-19a and miR-210 has higher diagnostic value for carotid artery stenosis.

Objective To explore the distribution and antibiotic resistance of the pathogens in the patients with central venous catheter-related blood stream infection in neurosurgical intensive care unit (NSICU).Methods A total of 452 patients with central venous catheter were identified in NSICU from January 2014 to January 2017.Medical records were reviewed retrospectively to examine the incidence of central venous catheter-related blood stream infections,and the pathogen distribution and antibiotic resistance profile.Results The incidence of central venous catheter-related blood stream infection was 4.6％ (21/452).The incidence of such infection was significantly higher for the catheter in femoral vein (10.5％) than in internal jugular vein (4.0％) and subclavian vein (2.6％) (x2=9.755,P=0.008).Twenty-six strains of pathogen were isolated from the 21 patients,including 13 (50.0％) grampositive bacteria,11 (42.3％) gram-negative bacteria and 2 (7.7％) fungal strains (Candida albicans and Candida parapsilosis each).The most common gram-positive bacteria were Staphylococcus epidermidis(5) and Staphylococcus aureus(3).The most common gram-negative bacteria were Klebsiella pneumoniae(4) and Serratia marcescens(3).The most frequently isolated pathogen of central venous catheter-related blood stream infections was S.epidermidis (19.2％) and K.pneumoniae (15.4％).The antimicrobial susceptibility testing showed that gram-positive bacteria were highly resistant to penicillin,erythromycin,oxacillin and clindamycin.Gram-negative bacteria were highly resistant to cefazolin and piperacillin.The two fungal strain were highly sensitive to fluconazole,voriconazole,itraconazole and amphotericin B.Conclusions The predominant pathogens of central venous catheter-related blood stream infections in NSICU patients are gram-positive bacteria.S.epidermidis and K.pneumoniae are the major pathogens with high level of antibiotic resistance.Aseptic procedures and rational antibiotic therapy according to antimicrobial susceptibility test should be emphasized to control the resistant strains.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Inulin has been used as a prebiotic to alleviate glucose and lipid metabolism disorders in mice and humans by modulating the gut microbiota. However, the mechanism underlying the alleviation of metabolic disorders by inulin through interactions between the gut microbiota and host cells is unclear. We use ob/ob mice as a model to study the effect of inulin on the cecal microbiota by 16S rRNA gene amplicon sequencing and its interaction with host cells by transcriptomics. The inulin-supplemented diet improved glucose and lipid metabolism disorder parameters in ob/ob mice, alleviating fat accumulation and glucose intolerance. The α diversity of gut microbial community of ob/ob mice was reduced after inulin treatment, while the β diversity tended to return to the level of wild type mice. Interestingly, Prevotellaceae UCG 001 (family Prevotellaceae) was obviously enriched after inulin treatment. A comparative analysis of the gene expression profile showed that the cecal transcriptome was changed in leptin gene deficiency mice, whereas the inulin-supplemented diet partially reversed the changes in leptin gene-related signaling pathways, especially AMPK signaling pathway, where the levels of gene expression became comparable to those in wild type mice. Further analysis indicated that Prevotellaceae UCG 001 was positively correlated with the AMPK signaling pathway, which was negatively correlated with markers of glycolipid metabolism disorders. Our results suggest that the inulin-supplemented diet alleviates glucose and lipid metabolism disorders by partially restoring leptin related pathways mediated by gut microbiota.
