Neural cell adhesion molecule (NCAM) is a glycoprotein expressing on the surface of neurons, glial cells, bone cells and natural killer cells. NCAM plays an important role in the process of cell - cell adhesion and cell migration, and is also a model protein to study polysialic acid. In this paper, NCAM gene from mouse mammary gland cells (NMuMG) was cloned into eukaryotic expression vectors pcDNA3.1(+) and transfected into mutant Chinese hamster ovary cells ldlD-14. The stable transfection over-expressing NCAM was obtained through the G418 selection and confirmed by Western blotting. Due to unique characters of ldlD-14 cells, carbohydrate chain of NCAM molecule can be easily manipulated with or without adding galactose in the serum free medium, and this modification can provide the basis for further studies on the effect of glycosylation on NCAM molecular function.

The aim of this study is to investigate the protection effect of tanshinone IIA (Tan) against triptolide (TP)-induced liver injury and the mechanisms involved. Acute liver injury was induced by intraperitoneal injection of TP (1 mg x kg(-1)) in mice. The activities of AST, ALT and LDH in serum and the levels of GSH, GST, GSH-PX, SOD, CAT and MDA in liver tissue were detected. The histopathological changes of liver tissues were observed after HE staining. Nrf2 translocation in liver tissue was detected by Western blotting, and real-time PCR was used to measure the expression levels of GCLC, NQO1 and HO-1 mRNA. The results showed that pretreatment with Tan significantly prevented the TP induced liver injury as indicated by reducing the activities of AST, ALT and LDH (P < 0.01). Tan pretreatment also prevented TP-induced oxidative stress in the mice liver by inhibiting MDA and restoring the levels of GSH, GST, SOD and CAT (P < 0.05). Parallel to these changes, pretreatment with Tan could attenuate histopathologic changes induced by TP. Furthermore, the results indicated that Tan pretreatment caused nuclear accumulation of Nrf2 as well as induction of mRNA expression of antioxidant response element (ARE)-driven genes such as GCLC, NQO1 and HO-1. These results indicated that Tan could protect against TP-induced acute liver injury via the activation of Nrf2/ARE pathway.

Objective To investigate the diagnostic value of the split-hand sign in amyotrophic lateral sclerosis ( ALS).Methods Ninety ALS patients, 41 patients with other neuromuscular disorders and 71 normal controls were recruited for conventional nerve conduction study.Compound muscle action potential ( CMAP) amplitude recorded from abductor pollicis brevis ( APB) , abductor digiti minimi ( ADM) and first dorsal interosseous (FDI), CMAP amplitude ratios, CMAP amplitude differences and split-hand index ( SI) were analyzed.Results The APB/ADM CMAP amplitude ratio was significantly lower in the ALS patients (0.44(0.44)) than that in the patients with other neuromuscular disorders (1.31(0.87);z=6.967, P<0.01) and the normal controls (0.99(0.42);z=7.687, P<0.01).The FDI/ADM CMAP amplitude ratio was significantly decreased in the ALS patients ( 0.79 ( 0.46 ) ) compared with that in the normal controls ( 1.23 ( 0.39 ); z =5.899, P <0.01 ).The FDI/ADM CMAP amplitude ratio was comparable between the ALS patients and the patients with other neuromuscular disorders ( 0.93 ( 0.62 );z=1.737,P=0.081).SI was significantly lower in the ALS patients (2.42 (3.14)) than that in the patients with other neuromuscular disorders (10.10(6.54);q=7.947, P<0.05) and the normal controls (17.93(8.32);q=10.827, P<0.05).SI <5.2 can help differentiate ALS from mimic disorders, with a sensitivity of 83.33% and specificity of 96.43%.Conclusions The split-hand sign appears to be a specific feature of ALS.SI robustly differentiates ALS from mimic disorders and potentially facilitates an earlier diagnosis of ALS.

Objective To compare the effect and toxicity of domestic idarubicin (IDA) and imported daunorubicin (DNR) in the treatment of acute leukemia (AL).Methods According to the random number table method,68 patients were randomly divided in IDA group with 35 patients and DNR group with 33 patients.In IDA group,the patients with acute myelocytic leukemia were treated following IA scheme (domestic idataubicin plus cytosine arabinoside) and the patients with acute lymphoblastic leukemia were treated following VICLP scheme (vincristine,domestic idataubicin,cyclophosphamide,lasparaginase and prednisone).In DNR group,the patients with acute myelocytic leukemia were treated following DA scheme (imported daunorubicin plus cytosine arabinoside) and the patients with acute lymphoblastic leukemia were treated following VDCLP scheme (vincristine,imported daunorubicin,cyclophosphamide,lasparaginase and prednisone).Results In IDA group,21 patients achieved a complete remission(CR),5 patients achieved a partial remission(PR),with a 74.2 ％ (26/35) remission rate (RR).In DNR group,the remission rate was 62.3 ％ (20/33).No differences of the remission rate was found between the two groups (t =0.89,P =0.50).17 patients were found remission over one year in IDA group,and 6 patients were in DNR group.The difference was statistically significant between the two groups (x2 =5.56,P =0.02).Conclusion IDA is more effective than DNR in AL treatment.The higher RR and longer remission time are found in IDA group than DNR group.IDA is effective and safe in the treatment of AL.

A total of 1 870 patients who had undergone thyroidectomy were investigated.The mean TSH level in patients with differentiated thyroid cancer (DTC) was significantly higher than that in patients with benign thyroid nodules[(1.95±1.69 vs 1.40±1.98)mIU/L,P＜0.01].DTC patients who had lymphatic metastasis or the diameter of tumor more than 10 mm had higher serum TSH level.Serum thyrotropin is an independent risk predictor for DTC.

Objective:To analyze the sleep quality and sleep structure of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) complicated with patent foramen ovale (PFO), and to study the effect of PFO on the sleep structure of OSAHS.Methods:Fifty-six patients with OSAHS complicated with PFO, 64 patients with simple OSAHS and 62 controls were collected from December 2018 to March 2020 in Centre of Sleep Disorders, the Second Affiliated Hospital of Zhengzhou University. Pittsburgh Sleep Quality Index and polysomnography were used to compare the sleep quality and sleep structure of the three groups.Results:Compared with the control group [6/62(9.68%)], OSAHS complicated with PFO group [54/56(96.43%)] and simple OSAHS group [53/64(82.81%)] had higher incidence of poor sleep quality (χ2=112.08, P<0.0l). Furthermore, compared with the control group, the OSAHS complicated with PFO group and simple OSAHS group showed reduced sleep efficiency [PSQI total score was 0.5 (0, 1), 2 (1, 3) and 2 (1, 2) respectively, H=74.549, P<0.01] and reduced proportions of rapid eye movement (REM; 20.45%±3.49%, 12.19%±5.95% and 15.11%±7.21%,respectively, F=21.17, P<0.01) and slow wave sleep (N3; 21.24%±4.12%, 14.15%±6.08%, 17.68%±6.35%, respectively, F=29.51, P<0.01); the N1 (4.47%±2.40%, 9.50%±5.34%, 9.55%±4.61%, respectively, F=30.07, P<0.05) and N2 sleep (53.88%±4.35%, 64.09%±7.49%, 58.14%±6.67% , respectively, F=46.21, P<0.05) were prolonged; the inocturnal lowest oxyhemoglobin saturation (SpO 2) level was lower, mean SpO 2 reduction at night was higher [3.00% (0, 4.00%),6.00% (5.00%, 8.75%) and 4.00% (4.00%, 5.00%), respectively, H=72.24, P<0.05], and periodic leg movement index [16.30(4.80, 32.82), 33.30(9.26, 54.80) and 23.10(8.38, 31.83),respectively, H=17.86, P<0.05], arousal index [11.60(7.73, 17.55), 23.90(14.03, 30.45) and 15.6(11.23, 20.78), respectively, H=22.80, P<0.05] and sleep apnea and hypopnea index (AHI; 1.60±1.38, 23.90±7.27 and 16.24±4.22,respectively, F=136.97, P<0.05) increased. Compared with the simple OSAHS group, the incidence of poor sleep quality was higher, the proportions of slow wave sleep (N3, F=29.51, P=0.047) and REM ( F=21.17, P=0.012) were decreased, N2 sleep ( F=46.21, P=0.000) was prolonged, mean SpO 2 reduction at night ( Z=54.28, P=0.000), wake after sleep onset [116.00(89.88, 143.00) min vs 135.00(118.50, 168.38) min, Z=25.71, P=0.023], arousal times [14.00(8.25, 8.00) vs 17.50(9.00,23.00),respectively, Z=19.68, P=0.041], microarousal ( Z=23.57, P=0.044), and AHI ( F=136.97, P=0.000) were increased in the OSAHS complicated with PFO group. Conclusions:OSAHS complicated with PFO patients had poor sleep quality and high incidence of sleep disorders. They had sleep disorder at night, which was characterized by the decrease of REM sleep and slow wave sleep, the prolongation of N2, the decrease of nocturnal SpO 2 and the increase of awakening times, and the increase of arousal times and AHI. PFO can aggravate the sleep disorder of OSAHS.

This study is to investigate the protection effect of schisandrin B (Sch B) against oxidation stress of HK-2 cells induced by cisplatin and the mechanisms involved. HK-2 cells were cultured and divided into different groups: solvent control group, cisplatin exposure group, positive group, Sch B treatment group. Cell viability and toxicity were evaluated by MTT and LDH assay. GSH level and SOD enzymes activities were also measured. DCFH-DA as fluorescence probe was used to detect ROS level by fluorescence microplate reader. Nrf2 translocation was detected by Western blotting. Real time Q-PCR was used to detect expressions of NQO1, HO-1 and GCLC mRNA level. The results showed that Sch B could significantly inhibit the decline of cell viability induced by cisplatin treatment (P < 0.05) and the protective effect was in a dose dependent manner. Furthermore, Sch B treatment significantly inhibited the increase of ROS level induced by cisplatin and reversed the decrease of GSH level (P < 0.05). When Sch B concentration was up to 5 micromol x L(-1), SOD enzyme activities were also enhanced significantly compared with that of the cisplatin group (P < 0.05). It was shown that Sch B could cause nuclear accumulation of Nrf2 in association with downstream activation of Nrf2 mediated oxidative response genes such as GCLC, NQO1 and HO-1. These results suggested Sch B could protect against the oxidative damage of HK-2 cells induced by cisplatin via the activation of Nrf2/ARE signal pathway.
