Abstract
Objectives: To analyze the status and temporal changes of disability-adjusted life year (DALY) for stomach and colorectal cancers among registered permanent residents in Changning District of Shanghai Municipality, and provide scientific basis for the prevention and treatment of stomach and colorectal cancers in this district. Methods: Using the cancer registration data of stomach and colorectal cancers from 2002 to 2019, we estimated the indices such as the DALYs, the DALY crude rates, the age-standardized DALY rates, etc. Then we used the Joinpoint regression model to calculate the average annual percent change (AAPC) and annual percent change (APC) to explore the temporal variations in different periods. Results: The DALYs of stomach and colorectal cancers in Changning District from 2002 to 2019 were 55 931 person years and 65 252 person years, respectively. The crude rates of DALY were 512.16/105 and 597.51/105, respectively. We observed a higher disease burden in men than in women, and the peak rate of DALY in stomach cancer was in the 75-79 years age group, while in colorectal cancer the rate was in the 85-years-or-older age group. Joinpoint regression analysis showed that from 2002 to 2019, the age-standardized DALY rate of stomach cancer showed a downward trend (AAPC=-3.86%, P<0.05), while the trend of colorectal cancer was not statistically significant(AAPC=-0.08%, P>0.05). However, the trends in the age-standardized DALY rates of colorectal cancer were different between males and females, with males showing an upward trend (AAPC=1.24%, P<0.05) and females showing a downward trend (AAPC=-1.67%, P<0.05). Conclusions: The DALY of stomach and colorectal cancers in Changning District of Shanghai showed a decreasing trend. Males and the middle-aged and elderly populations are still the key targets for disease prevention and control in this district.

Abstract
Objective: To investigate the efficacy of CT-guided percutaneous mandibular angle radiofrequency thermocoagulation (RFT) of facial nerve through stylomastoid foramen for the treatment of hemifacial spasm. Methods: A total of 82 patients with primary facial spasm who underwent CT-guided RFT in the Department of Pain Medicine of Zhejiang Integrated Traditional Chinese and Western Medicine Hospital and Department of Pain Medicine of the First Hospital of Jiaxing from January 2019 to June 2021 were retrospectively analyzed, including 27 males and 55 females, aged 24-85 (59±11) years. All patients were divided into three groups according to the different puncture approaches: anterior mastoid approach group (Group A, n=35), posterior mastoid approach group (Group P, n=25) and mandibular angle approach group (Group M, n=22). The puncture time, the minimum stimulating current inducing the twitch of facial muscles on the affected side, the temperature at the end of RFT and the duration of RFT at this temperature, the total treatment time, as well as the degree of facial paralysis and complications 1 day after operation were compared among the three groups. Results: The puncture time of the Group A, Group P and Group M was (31.0±4.9) min, (31.9±6.5) min and (35.3±5.9) min, respectively, and the difference was statistically significant (P=0.020). The puncture time of the Group M was longer than that of the Group A and P (both P<0.05). The minimum stimulation current inducing the twitch of the affected facial muscle in the three groups was (0.5±0.2) mA, (0.4±0.1) mA and (0.3±0.1) mA, respectively, with a statistically significant difference (P=0.000). The minimum stimulation current in the Group M was less than that in the Group A and P (both P<0.05). The temperature at the end of RFT of the three groups was (78.6±8.1) ℃, (76.6±8.3) ℃ and (67.0±8.4) ℃, respectively, and the difference was statistically significant (P<0.001). The temperature of the Group M was lower than that of the Group A and P (both P<0.05). There were no significant differences among the three groups in the duration of RFT at the final temperature, the total treatment time, and the degree of facial paralysis 1 day after operation (all P>0.05). No hematoma, infection, hearing impairment and other complications occurred in all patients. Conclusion: CT-guided percutaneous RFT through stylomastoid foramen is efficacious in the treatment of hemifacial spasm, and the mandibular angle approach provides better performance.

Abstract
Objective: To investigate the effect of guided bone regeneration (GBR) on marginal bone loss (MBL) in the region of the mandibular posterior tooth by using a retrospective cohort study, in order to provide reference for clinical practice. Methods: The research subjects were patients who received dental implants from October 2008 to June 2011 in the region of the mandibular posterior tooth at the Department of Oral Implantology, School of Stomatology, The Fourth Military Medical University. According to whether GBR was performed or not and the time of implant insertion, the patients were divided into the controls group (patients without bone grafting), simultaneous GBR implantation group, and delayed GBR implantation group. On this basis, the MBL was measured according to radiographs by comparing the marginal bone level from that of immediate postoperation 10 years ago. General data was collected and compared among groups, including modified plaque index (mPI), modified sulcus bleeding index (mSBI), probing depth (PD), and gingival papilla height. Results: The controls group (patients without bone grafting), implantation group, and delayed GBR implantation group followed 58, 76, 26 implants in 26, 32, 13 patients aging at (46.5±9.9), (45.5±10.7), (58.3±6.4) respectively. The duration of the follow-up was (11.2±0.7), (11.1±0.8), (11.1±0.9) years respectively. The 10-year implant survival rate was 100% (58/58), 100% (76/76), 100% (26/26). The MBL was (0.91±0.28), (0.84±0.27), (1.01±0.27) mm respectively. The MBL difference of patients with simultaneous GBR implantation and delayed GBR implantation showed statistical significance (P<0.05), but these two groups showed no statistical significance compared with the controls group (P>0.05). The mPI, mSBI, PD, and gingival papilla height of the three groups all had no significance on statistics (P>0.05). Conclusions: It can be concluded that there is no difference in long-term marginal bone resorption between simultaneous and delayed implantation with or without GBR (using autologous blood mixed with granular bone meal) in the posterior mandibular area.

Abstract
A set of differential isolates of Magnaporthe oryzae is needed for the postulation of blast resistance genes in numerous rice varieties and breeding materials. In this study, the pathotypes of 1,377 M. oryzae isolates from different regions of China were determined by inoculating detached rice leaves of 24 monogenic lines. Among them, 25 isolates were selected as differential isolates based on the following characteristics: they had distinct responses on the monogenic lines, contained the minimum number of avirulence genes, were stable in pathogenicity and conidiation during consecutive culture, were consistent colony growth rate, and, together, could differentiate combinations of the 24 major blast resistance genes. Seedlings of rice cultivars were inoculated with this differential set of isolates to postulate whether they contain 1 or more than 1 of the 24 blast resistance genes. The results were consistent with those from polymerase chain reaction analysis of target resistance genes. Establishment of a standard set of differential isolates will facilitate breeding for blast resistance and improved management of rice blast disease.

Abstract
Amino acids are the building blocks of proteins and serve as key molecular components upstream of the signaling pathways that regulate protein synthesis. The objective of this study was to systematically investigate the effect of essential AA ratios on milk protein synthesis in vitro and to elucidate some of the underlying mechanisms. Triplicate cultures of MAC-T cells and bovine mammary tissue explants (MTE) were incubated with the optimal AA ratio (OPAA; Lys:Met, 2.9:1; Thr:Phe, 1.05:1; Lys:Thr, 1.8:1; Lys:His, 2.38:1; and Lys:Val, 1.23:1) in the presence of rapamycin (control), OPAA, a Lys:Thr ratio of 2.1:1, a Lys:Thr ratio of 1.3:1, a Lys:His ratio of 3.05:1, or a Lys:Val ratio of 1.62:1 for 12 h; the other AA concentrations were equal to OPAA. In some experiments, the cells were cultured with OPAA with or without rapamycin (100 ng/mL) or with mammalian target of rapamycin (mTOR) small interference RNA, and the MTE were exposed to OPAA with rapamycin for β-casein expression. Among the treatments, the expression of β-casein was greatest in the MTE cultured with OPAA. In MAC-T cells, the OPAA upregulated the mRNA expression of SLC1A5 and SLC7A5 but downregulated the expression of IRS1, AKT3, EEF1A1, and EEF2 compared with the control. The OPAA had no effect on the mTOR phosphorylation status but increased the phosphorylation of S6K1 and RPS6. When the MTE were treated with rapamycin in the presence of OPAA, the expression of β-casein was markedly decreased. The phosphorylation of RPS6 and 4EBP1 also was reduced in MAC-T cells. A similar negative effect on the expression of RPS6KB1 and EIF4EBP1 was detected when the cells were cultured with either rapamycin or mTOR small interference RNA. The optimal AA ratio stimulated β-casein expression partly by enhancing the transport of AA into the cells, cross-talk with insulin signaling and a subsequent enhancement of mTOR signaling, or translation elongation in both MAC-T cells and bovine MTE.

Abstract
Effective control of the domain wall (DW) motion along the magnetic nanowires is of great importance for fundamental research and potential application in spintronic devices. In this work, a series of permalloy nanowires with an asymmetric notch in the middle were fabricated with only varying the width (d) of the right arm from 200 nm to 1000 nm. The detailed pinning and depinning processes of DWs in these nanowires have been studied by using focused magneto-optic Kerr effect (FMOKE) magnetometer, magnetic force microscopy (MFM) and micromagnetic simulation. The experimental results unambiguously exhibit the presence of a DW pinned at the notch in a typical sample with d equal to 500 nm. At a certain range of 200 nm < d < 500 nm, both the experimental and simulated results show that the DW can maintain or change its chirality randomly during passing through the notch, resulting in two DW depinning fields. Those two depinning fields have opposite d dependences, which may be originated from different potential well/barrier generated by the asymmetric notch with varying d.

Abstract
Nanoscale devices such as carbon nanotube and nanowires based transistors, memristors and molecular devices are expected to play an important role in the development of new computing architectures. While their size represents a decisive advantage in terms of integration density, it also raises the critical question of how to efficiently address large numbers of densely integrated nanodevices without the need for complex multi-layer interconnection topologies similar to those used in CMOS technology. Two-terminal programmable devices in crossbar geometry seem particularly attractive, but suffer from severe addressing difficulties due to cross-talk, which implies complex programming procedures. Three-terminal devices can be easily addressed individually, but with limited gain in terms of interconnect integration. We show how optically gated carbon nanotube devices enable efficient individual addressing when arranged in a crossbar geometry with shared gate electrodes. This topology is particularly well suited for parallel programming or learning in the context of neuromorphic computing architectures.

Abstract
In this paper the functions of helper T(Th) cell subsets, their cross regulation and agents affected their differentiation, as well as the role of Th subsets in the possible pathogenesis of autoimmune diseases were reviewed. Furthermore, a lot of opinions on autoimmune diseases therapy through restoration of Th subsets balance were mentioned. The available measurements to be used include up-regulation of CD1d, administration of relative cytokines, administration of Freund adjuvant, administration of monoclonal antibodies against cytokines, cytokine receptors, CD40 ligand or B7 molecule, as well as CTLA or CTLAIg pathway and so on.

Abstract
In vitro experiments showed that 250-500 micrograms.ml-1 of the polysaccharides isolated from Medicago sativa L (MSP) increased mouse lymphocyte uptake of [3H]thymidine (TdR) induced by PHA-p (0.15%), Con A (5 micrograms.ml-1), LPS (20 micrograms.ml-1), and PWM (2 micrograms.ml-1) at maximum by 5.13 +/- 0.81, 0.75 +/- 0.08, 4.52 +/- 0.36, and 0.86 +/- 0.24 folds, respectively. After MSP ip for 5 d, the average count of mouse splenic lymphocytes in 125 mg.kg-1 x d-1 group increased from 1.4 +/- 0.4 (x 10(7))/mouse to 3.6 +/- 0.5 (x 10(7))/mouse; in 250 mg.kg-1 x d-1 dose group increased to 13.5 +/- 0.3 (x 10(7)). MSP 125 mg.kg-1 x d-1 or 250 mg.kg-1 x d-1 ip for 5 d partially or completely antagonized the effect of cyclophosphamide (200 mg.kg-1 x d-1 x 1 d) on lymphocyte decrease, the average number of lymphocytes/mouse recovered from 1.04 +/- 0.23 (x 10(7)) to 2.1 +/- 0.4 (x 10(7)) and 2.9 +/- 0.6 (x 10(7)), respectively. In addition, the lymphocyte reactivity to Con A in MSP ip 125 mg.kg-1 x d-1 x 5 d group enhanced by 60%, in 250 mg.kg-1 x d-1 x 5 d group by 156%. The abilities of PWM-induced antibody production were elevated 51% and 78%, respectively.
