OBJECTIVETo investigate the safety and feasibility of laparoscopy-assisted combined radical resection for synchronous rectal and gastric cancer in elderly patients.

METHODSClinical data of two elderly patients undergoing laparoscopy-assisted combined radical resection for synchronous rectal and gastric cancer were analyzed retrospectively.

RESULTSThe two cases were 78 and 75 years old respectively. Both were complicated with many medical conditions. One case suffered from stage II cancer in the gastric body and stage IB rectal cancer, and the other suffered from stage IIIA gastric cancer and stage IB rectal cancer. Both cases had received laparoscopy-assisted combined radical resection for synchronous rectal and gastric cancer, with 5 cm of incision. The operative time was 260 and 255 min and the intraoperative bleeding was 60 and 80 ml respectively. No complication occurred intraoperatively. Time to resume oral intake was 4 and 5 days and length of postoperative hospital stay was 13 and 14 days respectively. No postoperative complication occurred. The patients were followed up for 13 and 12 months and no postoperative recurrence or metastasis was noticed.

CONCLUSIONLaparoscopy-assisted combined radical resection for elderly synchronous rectal and gastric cancer is safe and feasible when performed by surgeons with plentiful experience in laparoscopic technology, and associated with less injury and faster recovery.

Objective To identify genes in human cells infected with high pathogenic avian influenza viruses H5N1. Methods The lung carcinoma cells line A549 was infected with H5N1 and H1N1, respectively. We harvested the infected cells at the different time points after infection and screened the genes with differential expression via micro array technology. The candidate genes were selected and confirmed by quantitative real-time PCR. Results The spectrum of genes with the differential expression in the cells infected with H5N1 was obtained and 16 candidate genes were identified in the cellular apoptosis pathway, mTOR pathway, and the cellular immunity as well. Conclusion s Our Results suggest that H5N1 exert a stronger impact on eliciting apoptosis of infected cells than the common influenza virus H1N1.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To carry out the function evaluation and clinical adaptation service of assistive devices for a bilateral wrist-palm disarticulation case in the framework of International Classification of Functioning, Disability and Health (ICF). Methods By evaluating dysfunction and actual demand of the case, assistive devices were selected and applied in daily living, home, education and employment to achieve corresponding accessibility in activities and participation. Results and Conclusion The framework of ICF is important in evaluation of limb dysfunction and adaptation of assistive devices.

The biochemical integrity of the brain is necessary to maintain normal function. Oxidative damage is one of the mortal important reasons leading to the destruction of this integrity. The nervous system is enriched in phospholipid and polyunsaturated fatty acids (PUFAs). Due to the nature of high oxygen-consumption and rich lipids, brain is particularly vulnerable to oxidative damages. Phospholipid peroxidation is one of the results of imbalance in oxidation-antioxidant system. Once the antioxidant system is insufficient to resist oxidative damage, membrane phospholipids will be prone to free radical attack. Phospholipid peroxidation leads to a variety of toxic oxidation products, including membrane damage, mitochondrial dysfunction, rapid accumulation of amyloid, etc. Multiple proteins and nucleic acids can be covalently modified by peroxidation products, resulting in the loss of the protein functions, which eventually triggers programmed cell death and general neuroinflammation in brain, and ends up with an increased susceptibility to neurodegenerative diseases. Based on the knowledge of mechanisms of phospholipid peroxidation, this review focuses on the characteristics of phospholipid peroxidation as a key factor in the development of neurodegenerative diseases, in order to provide theoretical basis for targeted intervention of phospholipid peroxidation as a potential strategy to prevent neurodegenerative diseases.

BACKGROUNDIt remains controversial whether patients with Stage II colorectal cancer would benefit from adjuvant chemotherapy after radical resection. The aim of this study was to establish two mathematical models to identify the suitable patients for adjuvant chemotherapy.

METHODSThe current study comprised of two steps. In the first step, 353 patients with Stage II colorectal cancer who underwent surgical procedures at the Third Affiliated Hospital of Sun Yat-sen University between June 2006 and December 2015 were entered and followed up for 6-120 months. Their clinical data were collected and enrolled into the database. We established two mathematical models by univariate and multivariate Cox regression analysis to identify the target patients; in the second step, 230 patients under the same standard between January 2012 and December 2016 were entered and followed up for 3-62 months to verify the two models' validation.

RESULTSIn the first step, totally 340 surgical patients with Stage II colorectal cancer were finally enrolled in this study. Statistical analysis showed that tumor differentiation (TD) (P < 0.001), lymphovascular invasion (LVI) (P < 0.001), uncertain or positive margins (UPM) (P < 0.001), and fewer lymph nodes (LNs) (<12) retrieved (P < 0.001) were correlated with the overall survival (OS) and disease free survival (DFS). We obtained two models: (1) OS risk score = 1.116 × TD + 2.202 × LVI + 3.676 × UPM + 1.438 × LN - 0.493; (2) DFS risk score = 0.789 × TD + 2.074 × LVI + 3.183 × UPM + 1.329 × LN - 0.432. According to the models and cutoff points [(0.07, 1.33) and (-0.04, 1.30), respectively], patients can be divided into three groups: low-risk, moderate-risk, and high-risk. Moreover, the high-risk group patients could benefit from adjuvant chemotherapy. In the second step, totally 221 patients were finally used to verify the models' validation. The results proved that the models were accurate and feasible (P< 0.05).

CONCLUSIONSAccording to the predictive models, patients with Stage II colorectal cancer in the high-risk group are strongly recommended for adjuvant chemotherapy, thus facilitating the individualized and precise treatment.
