High temperature and humidity stress during seed growth and development of spring soybean can result in seed deterioration in South China. We isolated two genes (GmSBP and GmSBPL) encoding putative SBP proteins from soybean (Glycine max (L.) Merr.) to study their biological functions and response to abiotic stress,. The two SBP proteins are hydrophilic and incomplete membrane ones. Real-time quantitative (RT-PCR) analysis reveals that the expression of the two genes in the developing seeds of the seed deterioration resistant cultivar Xiangdou No. 3 and sensitive cultivar Ningzhen No. 1 was significantly affected by high temperature and humidity treatment. Meanwhile, the levels of sucrose and soluble sugar in the developing seeds of both cultivars were also affected under high temperature and humidity stress. During seed growth and development, the expression of the two genes as well as the levels of sucrose and soluble sugar reached the highest at 30 days after flower. GmSBP2 and GmSBPL were found to be differentially expressed in different soybean tissues. Sub-cellular localization indicated that two genes were located in cytoplasm and cell membrane. Our results indicate that GmSBP2 and GmSBPL might be involved in the response to abiotic stress, which will enrich our understanding of pre-harvest seed deterioration and resistance in soybean from one side.

Objective To explore a better method to repair cervical cicatricle contracture deformity.Methods The cervicai cicatrical contraction deformity was repaird by the cervico-shoulder island skin flap with blood supply crossing and abundant anastomotic branches of the neck-shoulder blood vessels. After removing the cervical scar, the flaps were designed according to the size of the wound to be repaired, and the clinical anatomy of crossing and abundant anastomotic branches of the neck-shoulder blood vessels. The secondary wound of donor site was closed directly if the donor region was small, or closed by skin graft. Results Sixteen patients in this clinic were operated with this method, and venous return dysfunction occurred in 1 case, but blood circulation was improved after treatment. All the flaps survived with good appearance and texture. The extensive flap was created and transferred to the anterior neck by one stage without pre-expansion which met some patients'requirement of repairing cervical cicatricle contracture deformity. Conclusion The cervico-shoulder island skin flap, with abundant blood supply, is a new method to repair cervical cicatricle contracture deformity.

Objective: To analyze and compare the features and strengths of different methods for calculating the biophysical properties of meridian points, and thus propose corresponding suggestions to fully achieve the research and application value of biophysical properties of meridian points.Methods: We searched and collected the literature on the imbalance of biophysical properties of meridian points between January 1, 2005 and March 1, 2020 in China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and PubMed database, and then analyzed, compared, and summarized the applied methods for calculating the imbalance degree of the biophysical properties of meridian points. Results: The current methods for calculating the imbalance degree of the biophysical properties of meridian points are diverse and can be summarized as the following three: direct comparison of the measured values of the left and right namesake points, difference method, and ratio method. The low uniformity of the calculation methods has limited the promotion and application of its research results. Conclusion: In future research on the biophysical properties of meridian points, multidisciplinary cooperation in terms of imbalance degree calculation methods, detection instruments, and health data models is necessary to achieve more widely applicable scientific conclusions and more generalized experimental results.

Background Corneal neovascularization ( CNV ) is a complication of many ocular surface diseases.It often worsen the pathological course.Effective therapy for CNV is still researching. Objective This study was to investigate the inhibitory effect of irradiation on CNV. Methods CNV models were established in 70 right eyes of 70 clean Wistar rats by corneal alkali burning.The models were randomized into β ray 10 Gy once irradiation group( 2 eyes),β ray 7 Gy multiple irradiation group( 17 eyes),β ray 10 Gy multiple irradiation group( 17 eyes),1％ cyclosporin A ( CsA ) eye drops group ( 17 eyes) and model group ( 17 eyes),and 6 matched normal rats were used as normal controls.All treatments started from the first day of the corneal alkali burning.CNV length and area were measured under the slit lamp every day.Corneal samples and homogenate were prepared 3,5,7 days after corneal alkali burning.The expressions of bcl-2,bax,vascular endothelial growth factor(VEGF) in rat corneas were detected by immunochemistry,VEGF proteins and VEGF mRNA were detected by Western blot and reverse transcription polymerase chain reaction (RT-PCR),respectively. Results Corneal ulceration was found in the βray 10 Gy once irradiation group and β ray 10 Gy multiple irradiation group.CNV length and area were much less in the β ray 7 Gy multiple irradiation group and 1％ CsA eye drops group compared with the model group on the seventh day after experiment( length:q=14.40,24.20,P＜0.01 ;area:q=17.80,14.00,P＜0.01 ).Immunochemistry revealed that compared with the model group,expressions of bcl-2 and VEGF proteins were weaker,but the expression of bax protein was stronger in the β ray 7 Gy multiple irradiation group and 1％ CsA eye drops group.RT-PCR showed that the expression of VEGF mRNA in cornea was lower in the β ray 10 Gy multiple irradiation group,β ray 7 Gy multiple irradiation group and 1％ CsA eye drops group in comparison with that in model group,and the results from Western blot showed the same pattern as RT-PCR. Conclusions Low dose irradiation of 90Sr-90Y ophthalmic applicator inhibits CNV formation after alkali burn.The study provide a new understanding of the irradiation for the treatment of CNV.

OBJECTIVETo evaluate the prognostic effects of neoadjuvant chemotherapy (NAC) in patients with local advanced gastric cancer.

METHODSWe retrospectively analyzed prognosis in 191 patients with advanced gastric cancer, of whom 71 were treated with NAC and 120 received surgery only between February 2007 and July 2013. Postoperative complication rate was recorded. Survival by clinicopathological features, pathological T and N stages, and histopathological tumor regression was retrospectively compared between the two groups.

RESULTSAccording to Response Evaluation Criteria in Solid Tumors, none of the 71 patients in the NAC followed by surgery group showed complete response, 36 showed partial response, 25 had stable disease, and 10 had progressive disease. The chemotherapy response rate was 50.7%; the disease control rate was 85.9%. Grade 3/4 adverse events were seen in less than 20% patients, with acceptable toxicities. No difference was found in the overall postoperative complication rates between the two groups (7 versus 22 cases, P=0.18). Median survival time was significantly different, at 54 months in the NAC combined with surgery group and 25 months in the surgery-only group (P=0.025).

CONCLUSIONIn patients with operable gastric adenocarcinomas, NAC can significantly improve overall survival without increasing surgical complications.
