Based on the results of oral glucose tolerance test( OGTT )and the levels of 1-h plasma glucose ( 1 hPG),793 subjects were classified into three groups:583 with NGTN ( normal 1 hPG in OGTT),127 with NGT1 H( higher 1 hPG in OGTT) and 83 with IGT( impaired glucose tolerance).NGT1H group had large waist circumference,higher body mass index,fasting plasma glucose( FPG),triglyceride,and lower high density lipoprotein-cholesterol than those of NGTN group.NGT1 H group had higher homeostasis model assessment insulin index ( 1.2 ± 0.6),lower homeostasis model assessment β3 ( HOMA-β ) (4.5 ± 0.7 ) and insulinogenic index (2.1 ±0.7) than those of NGTN group(0.5 ±0.6,4.8 ±0.7,2.7 ±0.9,respectively,all P <0.05 ).HOMA-β of NGT1 H group was higher than that of IGT group(4.5 ±0.7 vs.4.4 ±0.6,P <0.05 ).The results indicate that 1 hPG in OGTT may identify a condition of glucose metabolic abnormalities characterized by insulin resistance and reduced β-cell function.

Objective: To observe the clinical efficacy of grain-sized moxibustion in treating chemotherapy-induced myelosuppression for non-small cell lung cancer (NSCLC) and its effect on quality of life (QOL). Methods: Eighty NSCLC patients admitted to the Inpatient Department of Zhejiang Cancer Hospital between September 2016 and March 2018 were recruited and divided into an observation group and a control group by random number method, with 40 cases in each group. The two groups both received chemotherapy with paclitaxel plus cisplatin (TP regimen). The control group received oral administration of leucogen tablets starting from the first day of chemotherapy, 20 mg each time, three times a day, for consecutive 14 d; the observation group was additionally given grain-sized moxibustion, once a day, five days per week at a two-day interval, until the fourteenth day. The myelosuppression severity was observed and compared between the two groups prior to chemotherapy, at the 3rd, 7th and 14th days of chemotherapy; the QOL in the two groups was evaluated before chemotherapy, at the 14th and 21st days of chemotherapy. Results: Regarding myelosuppression, the peripheral blood indicators increased significantly at the 3rd day of chemotherapy in both groups (P<0.05 or P<0.01); at the 7th and 14th days of chemotherapy, the peripheral blood indicators presented a decreasing tendency in the two groups, but the level in the observation group was still significantly higher than that before chemotherapy (P<0.01); at the 3rd, 7th and 14th days of chemotherapy, the peripheral blood indicators in the observation group were higher than those in the control group (P<0.05 or P<0.01); the occurrence rate of myelosuppression in the observation group was significantly lower than that in the control group (P<0.01). The QOL score in the observation group was markedly higher than that in the control group at the 14th and 21st days of chemotherapy (both P<0.05). Conclusion: Grain-sized moxibustion can effectively improve myelosuppression after chemotherapy for NSCLC, reducing its occurrence and enhancing the patient's QOL.

OBJECTIVETo study changes of left ventricular remodeling (LVR) in hypertension patients with carotid atherosclerosis (CAS) of phlegm-dampness syndrome (PDS).
METHODSDoppler ultrasonography data of CAS were observed in 223 hypertension patients with CAS (as the hypertension group, including 119 patients of the PDS group and 104 of the non-PDS group), 81 CAS patients with non-hypertension, and 19 non-hypertension non-CAS patients (as the control group). The difference in the degree of LVR was compared among the above groups.
RESULTSThe left ventricular posterior wall thickness (LVPWT), inter ventricular septum thickness (IVS), E/A were higher in the hypertension group than in the non-hypertension group (P < 0.05). The left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic diameter (LVESD), stroke volume (SV) were higher in the soft plaque hypertension group and the soft plaque non-hypertension group than in the hard plaque group, the thickening intimal group, and the normal intimal group (P < 0.01 , P < 0.05). The LVEDD, LVESD, and SV were higher, and the ejection fraction (EF) was lower in the PDS hypertension group than in the non-PDS hypertension group (all P < 0.05). Of them, LVEDD, LVESD, and SV were higher in the soft plaque group than in the hard plaque group (P < 0.01), the thickening intimal group (P < 0.01) and the normal intimal group (P < 0.05). There was no statistical difference in PDS hypertension between the soft plaque group and the hard plaque group (P > 0.05).
CONCLUSIONThe hypertension patients with CAS of PDS might be correlated to LVR, and LVR was more obviously in the soft plaque patients.

OBJECTIVETo examine the antagonization of phentolamine against the effects of norepinephrine (NE) on the activity of pain-related neurons in the parafascicular nucleus of morphine-dependent rats.
METHODSElectric impulses were applied as nociceptive stimulus to the right sciatic nerve of morphine-dependent rats, and the discharges of the pain-related neurons in the parafascicular nucleus were recorded by extracellular recording method with glass microelectrodes.
RESULTSIntracerebroventricular injection of norepinephrine resulted in the inhibition of evoked response of the pain-excited neurons as well as the excitation of evoked response of the pain-inhibiting neurons. Both the inhibitory effect on the electric discharges of the pain-excited neurons and the excitatory effect on the pain-inhibiting neurons of norepinephrine were almost completely blocked by intracerebroventricular administration of phentolamine.
CONCLUSIONPhentolamine antagonizes the inhibitory effect of norepinephrine on the activity of pain-related neurons in the parafascicular nucleus in morphine-dependent rats, and norepinephrine may play an important role in the integration of the pain signal through the alpha-receptors.

The fruit shape is important quantitative trait closely related to the fruit quality. However, the genetic model of fruit shapes has not been proposed. Therefore, in the present study, analysis of genetic effects for fruit shape traits (fruit length and fruit perimeter) in sponge gourd was conducted by employing a developmental genetic model including fruit direct effects and maternal effects. Analysis approaches of unconditional and conditional variances were applied to evaluate the genetic behavior of fruit shape traits at economical and physiological maturation times. The results of variance analysis indicated that fruit length and fruit perimeter were simultaneously affected by fruit direct genetic effects and maternal effects. Fruit direct genetic effects were relatively more important for fruit shape traits at whole developmental period. The gene expression was most active at the economical maturation stage (1 approximately 12 d after flowering) for two shape traits, and the activation of gene was mostly due to direct dominance effects at physiological maturation stage (13 approximately 60 d after flowering). The coefficients due to different genetic effects, as well as the phenotypic correlation coefficients, varied significantly between fruit shape traits themselves at various maturation stages. The results showed that it was relatively easy to improve fruit shape traits for industrial purpose by carefully selecting the parents at economical maturation stage instead of that at physiological maturation stage.

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.

OBJECTIVEAnimal trials have demonstrated that memantine has neuroprotective effects on hypoxic-ischemic (HI) brain damage. Whether memantine can improve the long-term prognosis of rats with HI brain damage has not been reported. This study was designed to investigate the long-term effect of memantine therapy on neonatal rats with HI brain damage.
METHODSSixty postnatal 7-day-old newborn rats were randomly assigned into Normal control, HI and Memantine treated groups. Memantine (20 mg/kg) was administered immediately after HI in the Memantine-treated group. All subjects received a 5-day training of Morris water maze test from 23 days old. The escape latency (EL) was recorded at 28 and 35 days old.
RESULTSThe EL values of the Normal control, HI and Memantine-treated groups at 28 days old were 23.1 +/- 21.8, 35.1 +/- 5.3, and 20.6 +/- 3.4 seconds, respectively. There was a significant difference in the EL value between the HI and the Normal control groups (P < 0.05). The EL value of the Normal control, HI and Memantine-treated groups at 35 days old were 19.7 +/- 16.7, 35.6 +/- 32.3, and 16.3 +/- 13.2 seconds, respectively. A prolonged EL induced by HI still existed (P < 0.05 vs Normal controls) but memantine treatment shortened the EL (P < 0.01 vs HI group) at 35 days old.
CONCLUSIONSAdministering memantine immediately after HI can markedly increase the abilities of spatial discrimination, learning and memory and improve the long-term prognosis in rats with HI brain damage.
