BACKGROUND: It has been suggested that CT multiplanar reconstruction should be performed prior to the placement of axial pedicle screws to determine the anatomy of the C2 pedicle in each patient, to design the appropriate screw locus and diameter, and to evaluate the feasibility of screw placement to reduce the incidence of surgery-related complications. OBJECTIVE: To evaluate the feasibility of axis pedicle screw placement by morphologic classification of pediculoisthmic component with CT multiplanar reconstruction. METHODS: The CT data of 200 patients (400 axial pedicle screws) with cervical spine were retrospectively studied by using Siemens Syngo.Via software. According to the direction of the axis of the pedicle, the CT multiplanar reconstruction positioning line was adjusted to reconstruct the sectional image of the narrowest part of the pediculoisthmic component. According to its morphological characteristics, the narrowest part of the pediculoisthmic component was divided into three types: type 1, “hook” type: Type 1a outer diameter width (a1)> 0.4 cm, type 1b outer diameter width (a1)≤0.4 cm; type 2, “like circle/ellipse” type; type 3, “horizontal ellipse” type. The outer diameter width of the narrowest part of pediculoisthmic component (d1), medullary cavity width (d2), outer diameter height (a1), and medullary cavity height (a2) were compared among the three types, and the feasibility of pedicle screw placement of the three types was evaluated. RESULTS AND CONCLUSION: (1) A total of 400 axial pedicles included 269 cases of type 1, 130 cases of type 2, and 1 case of type 3. (2) The mean external diameter height between types 1 and 2 was not significantly different (P > 0.05). The mean medullary cavity height, mean outer diameter widths, and mean medullary cavity width were significantly different (P < 0.001). There were 42 cases (15.6%) of type 1 and 0 cases (0.00%) of type 2 with mean external diameter width ≤ 0.4 cm, and the difference was significant (P<0.001). There was only one case of type 3, whose external diameter height, medullary cavity height, outer diameter width and medullary cavity width were 1.20 cm, 0.84 cm, 0.64 cm and 0.31 cm, respectively. (3) These results confirm that axial pedicle screws can be safely inserted in patients with types 1a, 2 and 3, which requires no further measurement and assessment. Pedicle screw insertion should be performed with caution in type 1b patients. Therefore, in type 1 patients, the width of the narrowest outer diameter of the pediculoisthmic component should be further measured to evaluate the feasibility of axial pedicle screw placement.

The Tibet plateau is strongly sensitive to global climate change and the ecosystem is very fragile. Highland barley is a major crop on Tibetan plateau and sensitive to climate change. Authors reviewed the studies on the impact of current and future climate change on barley production over the Tibetan plateau and summarized the changes of agro-meteorological resources and agro-meteorological disasters, as well as the impact of climate change on barley cropping systems, fertility and yield. The results of studies have shown that a significantly warmer trend was observed on the Tibet plateau compared to the trend in other regions, together with increasing precipitation, reduced sunshine hours, and more frequent agro-meteorological disasters such as drought and floods under climate change. The potential planting boundary of highland barely moved to higher latitudes and altitudes under climate change, which led to the potential cultivated region increasing. The climate change shortened the growth period and showed a potentially positive impact on highland barley growth. Cultivar renewal combined with technological advances boosted highland barley yields and the ability to climate change adaption. The future climate change would shorten the growth period of highland barley, which posed a big threat to highland barley production and food security on the Tibet plateau. Existing reports are limited in terms of the study area and there are few studies on climate compounding impacts and integrated risk assessment. Therefore, it is necessary to gain a deeper understanding of the mechanism of climate change impact on barley production, the technology of dynamic assessment of meteorological disaster impact and comprehensive risk, and to develop effective measures to promote the adaptation of highland barley to climate change, which can ensure food security for Tibetans over Tibet plateau.

[Objectives]The study was conducted to examine tlie effects of replacing partial corn with rice bran on growth performance, intestinal morphology, intestinal development and giit microbiota of (Chinese new breed Suhuai pigs. [Methods]Twenty-four 160 day-old healthv Suhuai pigs with similar body weight were randomly allocated into 2 groups to receive basal corn-soybean diet containing 4.7% fibre and high fibrerice bran diet containing 7.5% fibre for 75 days, respectively. We collected feces on 0, 14,28 and 75 days for caboxymethyl cellulose(CMC)aud microbiota analysis. At the end of trial, all pigs were slaughtered and relative weight and length of gastrointestinal tract( GIT) were measured, and small intestine tissues were collected for morphologic observation. [Results] Average feed intake in the morning and average daily feed intake significantly decreased when pigs was fed with rice bran diets, and no significant difference was observed with average daily gain and feed to gain ratio (P>0.05). On 14 days of trial, rice bran diets increased CMC activity (P< 0.01) and the number of Rununoc0.05). Partially replacing of corn by rice bran increased large intestine weight ratio(P<0.05),as well as the duodenal and jejunal villus heights(P<0.01). crypt depths of jejunum (P<0.05).[Conclusions]Supplementation with 34.8% rice bran had no influence on growth performance of Suhuai pigs (50-90 kg), but improved small intestine villus heights, and had optimized effects on microbial community of large intestine.
