Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Bruton's tyrosine kinase(BTK)inhibitors are novel drugs targeted for the treatment of B-cell lymphoma.BTK inhibitors have pro-duced strong curative effects,especially for mantle cell lymphoma(MCL),chronic lymphocytic leukemia/small lymphocytic lymphoma(CLL/SSL),and Waldenstr?m's macroglobulinemia(WM).However,the adverse effect of bleeding has gradually been noted with the wide-spread use of BTK inhibitors in clinical practice.Bleeding events are caused by the off-target effects of BTK inhibitors,which affect platelet function through multiple signaling pathways during use.Bleeding affects patient treatment and threatens their quality of life.As such,the clinical management of bleeding should be strengthened.This paper provides a review of the mechanisms of action and clinical manage-ment of bleeding caused by BTK inhibitors.

Objective To explore the pharmacodynamic substances of Simiao Wan for the treatment of hyperuricemia and gout.Methods The pharmacological model of hyperuricemia was established.The chemical components in vivo and in vitro of Simiao Wan were analyzed by UPLC-Q-Exactive-MS.Based on the components absorbed in blood,the"active ingredient-target-pathway"network of Simiao Wan for regulating hyperuricemia and gout was constructed by network pharmacology method.The key ingredients were used for molecular docking with key targets[uricogenase(XDH),uric acid transporter(ABCG2,GLUT9,OAT1,URAT1)and inflammatory targets(PTGS2,TLR2,TLR4)]of hyperuricemia and gout.Finally,experimental verification was conducted according to the results of molecular docking.Our aim is to identify the key pharmacodynamic substances of Simiao Wan for the treatment of hyperuricemia and gout.Results Eighty-nine components of Simiao Wan were identified by UPLC-Q-Exactive-MS analysis,including 74 components absorbed in blood,which were confirmed as candidate ingredients.Network pharmacology was used to constructed"components absorbed in blood-target-pathway"network,and components absorbed in blood were matched with 116 targets of hyperuricemia and 173 targets of gout.It is involved in the regulation of biological processes,such as glucose and lipid metabolism,oxidative stress,inflammatory response,ERK1 and ERK2 cascade,MAPK cascade,PI3K signal transduction.Moreover,Simiao Wan plays a role in regulating the network of hyperuricemia and gout through regulating blood lipids and atherosclerosis,apoptosis,AGE-RAGE,TNF,PI3K-Akt,MAPK,TLRs,JAK-STAT,NF-κB and other signaling pathways.Molecular docking studies showed that berberine,phellodendrine,magnoflorine,jatrorrhizine,palmatine,obacunone,limonin,atractylodin,taxifolin,atractylenolide Ⅲ and β-ecdysterone had good affinity with uric acid synthase,uric acid transporter and inflammatory targets.Western Blot test showed that taxifolin negatively regulates the expression of URAT1.The above-mentioned compounds were the main pharmacodynamic substances of Simiao Wan for the treatment of hyperuricemia and gout.Conclusion This article describes the main pharmacodynamic substances of Simiao Wan in the regulation of hyperuricemia and gout,which can provides a scientific basis for the clinical application,improvement in quality evaluation and standard of Simiao Wan.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

Objective:To analyze the clinical features of latent autoimmune diabetes (LADA) in adults among newly diagnosed type 2 diabetes mellitus (T2DM), and to explore whether LADA diagnostic models can be established based on this.Methods:From May 2016 to January 2017, 302 patients with newly diagnosed T2DM in the outpatient and inpatient department of metabolism and endocrinology of Yueyang Central Hospital were analyzed. All of them were tested for glutamic acid decarboxylase antibody (GADA). According to the consensus of the Chinese Medical Association Diabetes Association (CDS) LADA diagnosis and treatment, they were divided into LADA group (18 cases) and T2DM group (284 cases). The general clinical data and clinical biochemical indexes of the two groups were analyzed; Multiple linear regression method was used to evaluate the feasibility of establishing LADA diagnostic model.Results:⑴ Compared with patients in the T2DM group, the patients in the LADA group had a younger age of onset, and " three more and one less" symptoms were more common ( P<0.05); the weight, body mass index (BMI), waist circumference, waist-to-hip ratio (WHR), triglycerides (TG), fasting C peptide (FCP), postprandial 2 h C peptide (2 h-CP), modified islet function index HOMA-islet (CP-DM), and modified insulin resistance index HOMA-IR (CP) in the LADA group were all lower, while high-density lipoprotein cholesterol (HDL-C) and HbA1c were higher ( P<0.05). ⑵ the linear regression method was used to analyze the multicollinearity of patients in LADA group and T2DM group. The biochemical indexes with statistically significant difference were selected as independent variables through correlation analysis, and the GADA value was used as dependent variable. The statistical results showed that the independent variables could not fully meet the conditions of multicollinearity regression analysis. Conclusions:⑴ Related clinical features and glucose metabolism indicators have differential diagnosis significance for LADA, but this study cannot be used for multiple linear regression analysis, and it is difficult to establish a diagnostic model for LADA. ⑵ LADA diagnosis is a comprehensive diagnosis, which should be combined with the results of islet autoantibody and clinical features.

Objective:To explore the reliability of preoperative diagnosis of low-grade infectious nonunion using haematological testing and radioisotope scanning (bone 3-phase image).Methods:A retrospective study was conducted of the 265 patients with bone nonunion who had been treated at Department of Orthopaedics, The Sixth People’s Hospital Affiliated to Shanghai Jiaotong University and at Department of Orthopaedics, The Eighth People’s Hospital Affiliated to Shanghai Jiaotong University from June 2010 to June 2018.They were 151 males and 114 females, aged from 19 to 64 years (average, 39.7 years).The nonunions occurred mainly at the tibia (113 cases) and the femur (72 cases).The preoperative results of their white blood cell count (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and radioisotope scanning were recorded.Taking the intraoperative pathological observations as the gold standards, the sensitivity, specificity, area under curve (AUC) of receiver operator characteristic (ROC) and Youden index were statistically analyzed respectively for every preoperative haematological tests and radioisotope scanning as well as for different combinations of the radioisotope scanning and one or more haematological tests.Results:Compared with the pathological observations, the radioisotope scanning showed a sensitivity of 80.7%, a specificity of 73.3%, an AUC of 0.770 and a Youden index of 0.540.In the combinations of radioisotope scanning and one haematological test, that of radioisotope scanning and CRP produced the largest AUC of 0.683, a sensitivity of 98.0%, a specificity of 70.3%, and a Youden index of 0.848.In the combinations of radioisotope scanning and 2 haematological tests, that of radioisotope scanning and WBC and ESR produced the largest AUC of 0.895, a sensitivity of 94.3%, a specificity of 67.3%, and a Youden index of 0.616 and all the 3 ones yielded an AUC of more than 0.880.The combination of radioisotope scanning and all the 3 haematological tests produced a sensitivity of 96.5%, a specificity of 79.7%, an AUC of 0.925 and a Youden index of 0.762.Conclusion:Combination of haematological testing and radioisotope scanning can be a reliable preoperative diagnosis of low-grade infection nonunion.

Objective To evaluate our noval rod-screw construct in anterior single-segmental decompression and fixation for the treatment of Denis type B burst fractures.Methods From February 2007 through May 2010,we treated 28 patients with Denis type B burst fracture.They were aged from 18 to 52 years (average,37.4 years).The fractures were located at T1 1 in 3 cases,at T12 in 10,L1 in 12,and L2 in 3.Of them,7 were complicated with unilateral pedicle fracture and 3 with bilateral pedicle fractures.According to the American Spinal Injury Association (ASIA) scale,the neurological deficits were rated as grade B in 11 cases,as grade C in 9,and grade B in 8.All the patients received anterior single-segmental decompression,titanium mesh and autogenous bone graft,and fixation with our noval rod-screw construct.The therapeutic efficacy was evaluated in terms of visual analogue scale (VAS),cobb angle,and spinal canal encroachment.Results The mean follow-up time was 26 months (range,from 17 to 33 months).The average length of surgery was 144 minutes(range,from 90 to 176 min);the mean blood loss was 580 mL (range,from 300 to 1 100 mL).The mean VAS score,cobb angle and spinal canal encroachment were improved from 8.2 ± 1.5,17.4° ± 4.3° and 53％ ± 16％ preoperatively to 2.7 ± 2.4,9.4° ± 5.8° and 4％ ±2％ at the final follow-up,respectively(P ＜ 0.05).None of the patients exhibited neurological deterioration.Conclusion Our noval rod-screw construct is a safe and effective device that can be used in the anterior single-segmental decompression and fixation for the treatment of Denis type B burst fractures.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disease characterized by a triad of progressive motor dysfunction, cognitive decline and psychiatric disturbances. The hallmark of HD is the distinctive choreiform movement disorder that typically has a subtle, insidious onset in the fourth to fifth decade of life and gradually worsens over 10 to 20 years until death. Notably, two-thirds of HD patients present with chorea and one third with mental changes. The prevalence of psychiatric symptoms is significantly higher than in the general population, and is estimated to be around 66–73%. Here, we report a unique case of subsequent onset of HD in a patient previously treated for schizophrenia and complicated by the extrapyramidal side effects to antipsychotics.
