Still, nearly 60%-90% of patients will undergo low anterior resection after surgery Syndrome (down anterior resection syndrome, LARS) LARS can seriously affect patients′ quality of life after surgery. This article will explain the concept, symptoms, possible pathogenesis, prevention, and treatment measures of LARS and provide help for the diagnosis, treatment and prevention of LARS.

AIM To investigate whether pioglitazone can protect cortical neurons from lipopolysaccharides(LPS)-induced neurotoxicity and the mechanisms responsible for this protective effect. METHODS After 7 d cultures，cultured cortical neurons were incubated with LPS 10 mg·L~(-1) for 4-24 h with or without other drugs. In co-incubation experiments, other drugs were added to the neurons 30 min or 1 h prior to incubation with LPS. The cell viability was assessed by MTT assay. The neuronal apoptosis was quantified by scoring the percentage of cells with apoptotic nuclear morphology after Hoechst 33258 staining. The cultured cells were then fixed on the 7th day and immunocytochemically stained with phosphorylated JNK1 antibody. The protein expressions of active caspase 3 and phosphorylated JNK1 were measured by Western blot. Nitric oxide (NO) generation was measured by Griess method. RESULTS The decrease of cell viability and the increase of apoptotic cells in cultured cortical neurons were observed incubated with LPS for 24 h compared with the normal controls. The cell viability of cortical neurons was decreased from (100.0±10.9)% in the normal control group to (72.3±2.1)% in the LPS-treated group and the apoptotic cell percentages were increased from (11.5±4.2)% in the normal control group to (39.5±8.2)% in the LPS group. LPS induced the increases in phospho-JNK1, active caspase 3 expression, and NO generation. Pioglitazone 0.01, 0.1 and 1 μmol·L~(-1), respectively inhibited LPS-induced decrease in cell viability and increase of apoptotic morphology, active caspase 3 expression in cultured neurons. In LPS+pioglitazone 1 μmol·L~(-1) group, cell viability was （97.8±9.7）%, the apoptotic cells percentage was (20.6±5.0)%, NO generation (6.8±1.3)μmol·L~(-1). Furthermore, pioglitazone also inhibited LPS-induced the increase in JNK1 phosphorylation and NO generation. JNK inhibitor SP600125 5 μmol·L~(-1) significantly inhibited LPS-induced neurotoxicity, cell viability was increased from (72.3±2.1)% to (109.8±11.8)%, the apoptotic cells percentage from (39.5±8.2)% decreased to (19.1±4.8)%, NO generation from （21.1±5.0）μmol·L~(-1) decreased to（4.0±1.3）μmol·L~(-1). The PPARγ antagonist GW9662 10 μmol·L~(-1) did not reverse the effects of pioglitazone. In LPS+pioglitazone 1 μmol·L~(-1)+GW9662 10 μmol·L~(-1) group, cell viability was (90.7±6.9)%, the apoptotic cells percentage was (23.4±4.1)%, and NO concentration was (5.8±0.7)μmol·L~(-1). CONCLUSION Pioglitazone protects cortical neurons against LPS insult at least via inhibiting JNK activity and NO generation, but not PPARγ activation.

Phosphoinositide 3-kinase/serine-threonine kinase (PI3K/AKT)has been found playing an important role in the pathogenesis of severe acute pancreatitis (SAP)in recent years,but the underlying mechanism has not been clarified.Aims:To investigate the role of PI3K/AKT in regulating the inflammatory response in SAP by evaluating the effect of insulin-like growth factor-Ⅰ (IGF-Ⅰ)and wortmannin,the agonist and inhibitor of PI3K/AKT on Toll-like receptor 4 (TLR4)signaling pathway in macrophage cell line RAW264.7.Methods:RAW264.7 cells were treated with different concentrations of lipopolysaccharide (LPS ), IGF-Ⅰ and wortmannin, respectively, and cell viability was determined by CCK-8 assay.RAW264.7 cells were divided into blank control group (no treatment),LPS group (LPS 1 μg/mL),IGF-Ⅰ group (IGF-Ⅰ 100 ng/mL +LPS 1 μg/mL),wortmannin group (wortmannin 100 nmol/L +LPS 1 μg/mL)and IGF-Ⅰ +wortmannin group (wortmannin 100 nmol/L +IGF-Ⅰ 100 ng/mL +LPS 1 μg/mL).Protein expressions of tumor necrosis factor-α(TNF-α)and interleukin-6 (IL-6)were detected by ELISA;mRNA expressions of TLR4,myeloid differentiation factor 88 (MyD88),AKT,PI3K,p38 mitogen-activated protein kinase (p38MAPK)and nuclear factor-κB (NF-κB)were determined by real-time PCR.Results:After treated with LPS,IGF-Ⅰand wortmannin, respectively,no differences in cell viability of RAW264.7 cells were found between different concentrations groups (P>0.05).Protein expressions of TNF-αand IL-6 in LPS,IGF-Ⅰ,wortmannin and IGF-Ⅰ +wortmannin groups were significantly higher than those in blank control group (P<0.05 ).Protein expressions of TNF-αand IL-6 in wortmannin group were significantly lower than those in LPS and IGF-Ⅰ groups (P<0.05),and those in IGF-Ⅰ+wortmannin group were significantly lower than those in IGF-Ⅰ group (P<0.05).In LPS group,mRNA expressions of AKT and PI3K as well as TLR4 and its downstream molecules MyD88,p38MAPK and NF-κB were significantly higher than those in blank control group (P <0.05 ).Expressions of all above-mentioned mRNAs in IGF-Ⅰ group were further increased and significantly higher than those in LPS group (P<0.05).Expressions of all above-mentioned mRNAs in wortmannin group were significantly lower than those in LPS and IGF-Ⅰ groups (P<0.05 ),and those in IGF-Ⅰ+wortmannin group were significantly higher than those in wortmannin group (P<0.05),but significantly lower than those in IGF-Ⅰ group (P<0.05).Conclusions:PI3K/AKT might regulate TLR4 signaling pathway and its downstream molecules in macrophages, thereby affects the expressions of inflammatory cytokines and being involved in the pathogenesis of inflammatory response in SAP.

Objective To investigate the specific activity of 24Na per unit neutron fluence,AB/Φ,in blood produced for Chinese reference man irratiaded by 252Cf neutron source,and to analyze the effects of scattering neutrons from ground,wall,and ceiling in irradiation site on it.MethodsA 252Cf neutron source of 3 × 108 n/s and the anthropomorphic phantom were used for experiments.The phantom was made from 4 mm thick of outer covering by perspex and the liquid tissue-equivalent substitute in it.The data of phantom dimensions fit into Chinese reference man.The weight ratios of H,N,O and C in substitute equal from source to long axis of phantom were 1.1,2.1,3.1 and 4.1 m,respectively.Both the neutron source and the position of xiphisternum of the phantom were 1.6 m above the floor.ResultsThe average specific activity of 24Na per unit neutron fluence was related to the irradiation-distances,d,and its The AB/ΦM corresponds to that of phantom irradiated by plane-parallel beams,and the value is about more 3% than that by BOMAB phantom reported in literature.It has shown that floor-( wall-)scattered neutrons in irradiation site have significant contribution to the specific activity of 24Na ,but they contributed relatively little to the induced neutron doses.Consequently,using the specific activity of 24 Na for assessing accidental neutron doses received by an individual,the contribution of scattered neutrons in accident site will lead dose to be overestimated,and need to be correct.

In order to study the effect of magnetic action on the rabbit tests, we fed the rabbit with magnetized water and embedded the small magnetic disc at "guanyuan point". Five months later, the total sperm number as well as the sperm number per 100 mg in epididymal tail of the experimental group significantly increased than those of the control group. The observation by light microscope and scanning electron microscope showed more increased spermatogone, spermatoblast and sperm in the experimental group than in the control. This study indicates that drinking magnetized water and embedding magnet disc at "guanyuan point" have a spermatogenic effect

ObjectivesTo report pathological and genetic features of 6 Chinese families with Xlinked Charcot-Marie-Tooth disease type 1 ( CMTX1 ).Methods The index cases from 6 families with CMTX1 are males with onset of disease between 11 and 24 years old.All of them had distal leg muscle weakness,accompanied with areflexia and sensory loss in the feet.Additionally,the index 1 presented with recurrent encephalopathy and the index case 5 with cerebellar ataxia.Peripheral neuropathy was found in 12 family members,while other 7 members showed talipescavus and hyporeflexia.Sural nerve biopsies were performed in all index cases.Connexin 32(Cx32) gene was analyzed in the index cases,8 affected and 10unaffected family members as well as 50 healthy women control subjects.ResultsMild to moderate loss of myelinated fiber with axonal degeneration and regeneration clusters were found in all index cases. Thin myelin fibers were found in 5,small onion bulbs in 3 and inflammatory infiltrates in 2.Five novel mutations (I20T,I127F,D178G,A197V,403_404insT) and one L10L synonymous mutation were detected in the 6index cases and their affected family members.The same mutations,in heterozygous state,were detected in 4 female family members without clinical symptoms,but not found in 6 male unaffected family members.The same mutations were not found in healthy control subjects.ConclusionsThe CMTX1 patients in our study present predominantly axonal lesions.Frequent novel Cx32 gene mutations indicated that private mutations may be common in Chinese CMTX1 patients.

Objective:To explore the efficiency of a new scoring system of gastric cancer screening for early gastric cancer in health examination population.Methods:The risk score of gastric cancer was assessed based on the new scoring system in health examination population. A notice for further gastroscopy was sent to the medium-risk and high-risk people. Gastroscopy was performed on those who agreed to undergo the examination.Results:From January to April 2019, a total of 5 357 people in health system visited the Physical Examination Center of Shanghai Songjiang Clinical Medical College of Nanjing Medical University for health examination. Seven hundred and forty people were classified as medium- and high-risk groups by the new screening system, 576 in medium-risk group, and 164 in high-risk group. Among them, 131 cases (17.70%) came for further gastroscopy, of whom 91 (69.47%) were in the medium-risk group and 40 (30.53%) in the high-risk group. After gastroscopy, 4 cases of gastric cancer and 1 case of esophageal cancer were detected, and both were early cancer. In the medium-risk group, 2 cases (2/91, 2.20%) of early gastric cancer and 1 case (1/91, 1.10%) of early esophageal cancer were found. In the high-risk group, 2 cases (2/40, 5.00%)of early gastric cancer were found. The tumor detection rate of high-risk group (5.00%) was higher than that of medium-risk group (3.30%), but there was no significant difference ( P>0.05). Conclusion:Risk stratification with the new scoring system of gastric cancer screening can improve the detection rate of early gastric cancer.
