Referring to ZHANG Xichun's experience in treating dysentery from cold-fire accumulation， the treatment of ulcerative colitis （UC） in this paper can be divided into three stages including cold-fire accumulation stage， excessive heat and putrid intestine stage， and healthy qi deficiency and pathogen lingering stage. For people with slippery and excess pulse in the cold-fire accumulation stage， Xiaochengqi Decoction （小承气汤） added with Baishao （Radix Paeoniae Alba） and Gancao （Radix et Rhizoma Glycyrrhizae） can be used for purgation， while those with deficient pulse， Huazhi Decoction （化滞汤） or Xieli Decoction （燮理汤） can be used. In the excessive heat and putrid intestine stage， Tongbian Baitouweng Decoction （通变白头翁汤） and Jiedu Shenghua Elixir （解毒生化丹） are suggested. In the healthy qi deficiency and pathogen lingering stage， it is advised to use Jiedu Shenghua Elixir added with Shanyao （Rhizoma Dioscoreae）， and Sanbao Porridge （三宝粥）. Additionally， the medication rules， dosage and administration characteristics of Huanglian （Rhizoma Coptidis）-Rougui （Cortex Cinnamomi）， Yadanzi （Fructus Bruceae）， Diyu （Radix Sanguisorbae）， Shanyao and Liuhuang （Sulphur） by ZHANG Xichun have been summarized with the help of modern pharmacological research， so as to provide new ideas for the treatment of UC by TCM.

The difficulty of wound healing in patients is a difficult problem that doctors in all clinical departments may encounter, and there is still no good solution. Resveratrol is a kind of natural active substance, which has anti-inflammatory, antioxidant, antibacterial, and angiogenesis promoting effects, and is a potential drug to promote wound healing. However, the clinical application of resveratrol is limited due to its low bioavailability. In this review, the molecular mechanism of resveratrol in promoting wound healing and its administration methods in wound treatment were reviewed to provide ideas for the redevelopment of resveratrol.

After the compatibility of Astragali Radix and Atractylodis Macrocephalae Rhizoma, most of the effective components of Astragali Radix increase, and the bioavailability is improved. Compared with the application of the two drugs alone, it can enhance the effects of immune regulation, anti-tumor, diuresis, lung protection, regulation of flora, and intestinal protection. However, the optimal compatibility ratio of Astragali Radix- Atractylodis Macrocephalae Rhizoma pair to exert various pharmacological effects still needs to be clarified. The drug pair and related preparations are mostly used in the treatment of nephropathy, but its mechanism of action needs to be further elucidated.

Objective:To investigate the medicinal plant resources in Saertu District, Heilongjiang Province so as to provide scientific foundation for the protection rational development and utilization of wild medicinal plant resources in this region.Methods:According to the technical specification requirements of the fourth national census of Traditional Chinese Medicine (TCM) resources, the wild medicinal plant resources in Saertu area were analyzed.Results:A total of 36 samples were completed, in this survey among which contains a total of 166 species of wild medicinal plant resources, belonging to 118 genera of 45 families, including 37 species of key medicinal materials.Conclusion:The TCM resource in Saertu is relatively scarce, and the species and resource distribution of TCM in this region have been basically found out, which can provide reliable information for the establishment of TCM resource protection zones in Saertu and expanded to the entire province.

The incidence of postoperative excessive bleeding and reexploration is relatively high, and it will bring a series of serious complications, such as an additional surgery, a longer intensive care unit stay, longer time on mechanical ventilation, an increase need of allogeneic blood product transfusions and increased mortality. However, the understanding of postoperative excessive bleeding and reexploration in China is significantly different from the international level, and the understanding of postoperative excessive bleeding and reexploration after cardiac surgery in clinical work is still not enough. This review will focus on some problems, such as related factors analysis of postoperative excessive bleeding, hemostatic process optimization and the serious complications of reexploration after cardiac surgery.

Objective: To explore the differences and correlation between the target volumes based on deformation registration (DIR) using preoperative prone diagnostic magnetic resonance (MR) imaging and postoperative prone computed tomography (CT) simulation imaging for patients undergoing breast-conserving surgery (BCS). Methods: Eighteen breast cancer patients suitable for external-beam partial breast irradiation (EB-PBI) after BCS were enrolled. Preoperative prone diagnostic MR and postoperative prone CT scan sets were acquired during free breathing for all patients. The gross tumor volume (GTV) delineated on the preoperative diagnostic MR images was defined as GTV_MRI, the clinical target volumes (CTV_{MRI+ 1} and CTV_{MRI+ 2})were defined as 10 and 20 mm margins around the GTV_MRI, and the planning target volume (PTV_{MRI+ 1} and PTV_{MRI+ 2}) were defined as 15 and 25 mm margins around the GTV_MRI, respectively. Tumor bed (TB) delineated on the postoperative prone CT simulation images acquired during free breathing was defined as GTV_TB, CTV and PTV were defined as 10 and 15 mm margins around the GTV_TB, respectively. The target volume of the whole breast contoured on the MR and CT images were defined as CTV_Breast-MRI and CTV_Breast-CI, respectively. The MR and CT images were registered deformably in MIM software system. Results: The GTV_TB, CTV_TB and PTV_TB were significantly greater than GTV_MRI, GTV_{MRI+ 1} and PTV_{MRI+ 1}, respectively (Z=-3.593, -3.593, -2.983, P<0.05). Meanwhile, the CTV_TB and PTV_TB were significantly less than the CTV_{MRI+ 2} and PTV_{MRI+ 2}, respectively(Z=-2.722, -2.853, P<0.05). The conformal index (CI) and degree of inclusion (DI) of GTV_TB-GTV_MRI, GTV_TB-CTV_{MRI+ 1}, CTV_TB-GTV_MRI and CTV_TB-GTV_{MRI+ 1} based on center-coincidence of the compared targets were better than those based on DIR of the thorax(Z=-3.724、-3.724、-2.591、-3.593, P<0.05; Z=-3.724、-3.724、-3.201、-3.724, P<0.05). Conclusions For the patients enrolled for prone EB-PBI, target volumes delineated on the preoperative prone MR images were significantly smaller compared to that on the postoperative prone CT images, but a statistically significant positive correlation was found between the MR and CT target volumes. There were still relatively poor spatial overlap whether for the whole breast or the targets between the preoperative prone diagnostic MR images and the postoperative prone simulation CT images based on DIR. Therefore, it is infeasible to guide postoperative EB-PBI target delineation using the preoperative prone diagnostic MR images.

Objective To investigate the difference of target volumes and dosimetric parameters between supine and prone positions for external-beam partial breast irradiation (EB-PBI) after breastconserving surgery (BCS).Methods Thirty breast cancer patients with T1N0M0 stage who underwent three-dimensional conformal radiation therapy (3D-CRT) EB-PBI after BCS were enrolled from July 2016 to April 2017.Supine and prone scan sets were acquired during free breathing for all patients.Target volumes and organs at risk (OARs) including heart,ipsilateral lung and bilateral breast were contoured by the same radiation oncologist.The tumor bed (TB) was determined based on surgical clips.The clinical target volume (CTV) consisted of the TB plus 1.0 cm margin and the planning target volume (PTV) was CTV plus 0.5 cm.Dosimetric parameters for target volumes and OARs were compared between supine and prone positions.Results The median volumes of the TB,the CTV and the PTV in supine were 14.40 cm3,57.35 cm3,108.85 cm3 and 14.10 cm3,62.60 cm3,113.70 cm3 for prone positions,respectively.The CTV and PTV in prone position were significantly greater than those in supine position,respectively (Z=-3.01,-2.87,P ＜0.05),but the TBs were not statistically different (P ＞0.05).The median homogeneity indexs (HI) in supine position was less than those in prone position (Z =-3.137,P ＜0.05),while the mean conformal indexs (CI) was increased with prone positioning (t =9.034,P ＜ 0.05).The mean dose (D) to the heart in the supine position was significantly lower than that in prone (0.34 and 1.19 Gy,Z =-4.12,P ＜0.05).The D to the ipsilateral lung in the prone position was significantly lower than that in supine (1.59 and 1.72 Gy,Z =-2.18,P ＜ 0.05).There was not significantly statistical difference for the D to the ipsilateral breast between two positionings (10.01 and 10.40 Gy,P ＞0.05).Conclusions It was feasible to carry out 3D-CRT EB-PBI in prone position in free breathing for Chinese breast cancer patient,with primary advantages of better CI and the significantly lower radiation dose to the ipsilateral lung.
