Spleen deficiency syndrome is one of the common syndromes of traditional Chinese medicine. It is often seen in gastrointestinal mucosal diseases such as peptic ulcer and chronic gastritis. Studies have found that rats with spleen deficiency syndrome show damaged or shedding gastric mucosa, mucosal focal erosion,different degrees of reduction of gastric main cells,parietal cells and gastric glands, as well as the compensatory state of gastric parietal cell ultrastructure[1]. Therefore, some people think that spleen deficiency syndrome is the integration of multi-system and multi-functional abnormality based on the characteristics of digestive system morphology and dysfunction; gastrointestinal mucosal lesions and their corresponding dysfunction may be one of the pathological basis of spleen deficiency syndrome.

Studies have shown that trefoil factor 1 (TFF1) has the role in protection of gastric mucosa and repair of the injury[2-4]. On one hand, it plays a physiological function through the combination with Mucin 5ac(MUC5AC) ligand; on the other hand, it’s involved in the reconstruction of gastric mucosal injury by inducing the epidermal growth factor receptor (EGFR) mediated signaling pathway. A large number of clinical studies have shown that acupuncture treatment has exact therapeutic efficacy on deficient cold of spleen and stomach, and the role of moxibustion therapy is more obvious[5]. Our previous study showed that gingerpartitioned moxibustion could not only improve the clinical symptoms of patients with spleen deficiency syndrome, but also had antioxidant effect[6]. Focused on TFF1, our current study explored the protective effect and the dose-effect characterization of gingerpartitioned moxibustion on the gastric mucosa in rats with spleen deficiency syndrome on the basis of our previous studies, therefore, to provide evidence for the clinical application of ginger-partitioned moxibustion in treatment of spleen deficiency syndrome.

1.3 Modeling and model evaluation

Models were prepared according to the method developed by Peng Y and others[7]: except rats in group A, all rats in other four groups received intragastric administration of 4 ℃ and 200% concentrated Da Huang (Radix et Rhizoma Rhei) [10 mL/(kg·bw)], twice a day for 14 continuous days. The body weight, diet and water consumption, coat color, stools, mental status and behavior change were observed.

1.6.1 General symptom observation

1.4 Acupoints

Point positioning was conducted according to the method normally used for animal and personification control method based on Experimental Acupuncture Science[8]. The navel is the intersection of the lower 1/4 and upper 3/4 on the line between sternoclavicular symphysis and pubic symphysis.

Zusanli (ST 36): At back lateral of the knee joint, and about 5 mm below the capitulum fibulae.

Zhongwan (CV 12): At midpoint on the line between the umbilicus and xiphoid process, about 20 mm above the navel.

1.5 Treatment and sampling

Group A: Rats were not subject to modeling, with a 15 min bundling each day but without moxibustion for 8 continuous days.

(2)对于节点剩余能量的均衡性模型，从最里层出发，以最小化相邻两层节点剩余能量方差为目标函数，逐层求解得到充电小车在任意相邻两层停留时间的函数关系，同时设置能量阈值作为约束条件确保节点存活，最终确定小车在各层的停留时间.

Group C1: Rat’s hair was shaved (around 2.0 cm ×2.0 cm) at bilateral Zusanli (ST 36) and Zhongwan (CV 12)to expose local skin tissue, and the points were disinfected with ethanol treated cotton ball. Rats were fixed in a supine position with a self-made rat clip, and subjected to moxibustion treatment when they were still. Fixed the ginger slices (2-3 mm in thickness, 1.8 cm in diameter) with moxa cones on the acupoints, 3 cones daily (about 15 min) for constant 8 d.

EGFR protein expression in gastric mucosa of group C2 and C3 was higher than that in group C1 (P＜0.01),but there was no significant difference between group C2 and C3 (P＞0.05), indicating no significant difference in regulation of EGFR protein expression in gastric mucosa between 6 and 9 moxa-cone ginger-partitioned moxibustion (Table 4).

Chinese medicine indicates that ‘a strong spleen helps to defend against invasion of pathogen’,suggesting that the spleen and stomach are closely related to the defensive function, meanwhile, spleen and stomach are intrinsically linked with the digestive system, especially the local defensive function of the gastric mucosa.

对于类似机组主轴密封、迷宫环冷却供水冷却作用后直接流入流道的用户，无法通过自循环供水系统实现冷却功能，故该类用户建议采用稳定的施工支洞渗漏水或其他市政供水作为汛期的备用冷却水源。对于消防供水建议设置消防水池作为汛期消防供水的备用水源。

Therefore, it should focus on the spleen and stomach to correct the pathological basis of spleen and stomach deficiency, and improve the gastric mucosal selfprotection/defensive function during the treatment.

2 Results

2.1 Comparison of syndrome scores in rats with spleen deficiency syndrome among groups

After modeling, in addition to rats in group A, all the other rats showed a slow increase of body weight,decreased appetite and activity, curled up, with loose stool and dull hair; the syndrome scores of spleen deficiency in group B, C1, C2 and C3 were higher than those before modeling, as well as in group A (P＜0.01),suggesting that the model was successful. After treatment with ginger-partitioned moxibustion, the symptoms of spleen deficiency were not obvious in group C1, C2 and C3, and the syndrome scores of spleen deficiency were lower than those of group B (all P＜0.01).

The slices were heated at 60 ℃ for 45 min; dewaxed to water: in xylene for 10 min × 2 times, then in 100%,95%, 85% and 75% ethanol for 5 min, and washed with distilled water for 5 min; repair of the antigen by heating: immersed the slices in 0.01 mol/L citrate buffer(pH 6.0) and heated to boiling by electric furnace or microwave oven and switched off the power, repeated twice with an interval of 5-10 min; washed with 0.01 mol/L PBS (pH 7.2-7.6) for 3 min × 3 times after cooling. Added 3% H2O2, incubated at room temperature for 10 min to inactivate endogenous enzyme, and washed 3 min × 3 times with PBS.Incubation with primary antibody: added appropriate dose of diluted EGFR primary antibody, incubated at 4 ℃ overnight, rinsed 5 min × 3 times with PBS;incubation with secondary antibody: added 50-100 μL anti-rabbit IgG antibody-HRP polymer, incubated at 37 ℃ for 30 min, washed with PBS for 5 min × 3 times.

Compared with group C1, the syndrome scores of spleen deficiency were lower in rats of group C2 and C3(P＜0.01), but there was no significant difference in the syndrome score of spleen deficiency between group C2 and C3 (P＞0.05),(Table 2).

3 Discussion

Gastric mucosal injury is the main pathological factor leading to acute and chronic gastritis, gastric ulcer and other diseases, mainly reflected by the increased gastric mucosal attack factors and decreased gastric mucosal self-protection/defense, while the gastric mucosal injury is closely related to both the pathological process and syndrom of spleen deficiency[9]. With the establishment of the diagnostic standard of spleen deficiency syndrome, various animal models of spleen deficiency were successfully replicated. At home and abroad, many institutes have confirmed that feeding rhubarb decoction to animals is the most stable method to establish of the spleen deficiency model[10], after study and exploring of the functional changes,physiological and biochemical changes, as well as the immunocompromice.

在财务管理过程中的预算执行力度上，主要存在两个方面问题，一是较为随意的中学预算执行，在预算编制被批准的基础上，各个部门就要配合财务部门进行预算执行，但往往在预算执行的过程中，由于前期的预算编制中存在一定问题，导致预算在执行过程中遇到阻碍，这时，一些相关的财务执行人员就会依靠自己的意愿，去对资金进行分配使用，导致预算执行力度出现比较随意的现象，影响了预算的执行力度；二是较为缓慢的中学预算执行。财务部门在预算编制完成的基础上，还需要上级部门的层层审批才可以进行预算执行，较为缓慢地执行影响了财务工作的有效进展。

Group C3: The treatment before moxibustion,materials and acupoints used for moxibustion were all same as in group C1. Ginger-partitioned moxibustion was performed for 9 cones (about 45 min) each day for 8 continuous days.

Rats in each group were fasted for 24 h and deprived of water for 6 h at the end of treatment. Blood samples were collected after anesthesia using 10% urethane(10 mL/kg·bw). After the belly was opened, stomachus pyloricus and gastric cardia were ligated with hemostatic forceps, then the esophagus and duodenum were cut off to separate the whole stomach. The stomach was opened along the arcus major ventriculi,and the stomach residue was rinsed with iced saline. On the super-clean bench, 1.0 cm × 0.5 cm size of tissue was sampled from the gastric mucosa appearing obvious injury, rinsed with saline, and fixed with 4%paraformaldehyde at 4 ℃ for 24 h. The 5 μm thick slices were used for enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry assay.

Moxibustion is one of the external therapies in traditional Chinese medicine. The warm stimulation by moxibustion can produce a good warm and steady effect, thus playing a role in disease prevention and treatment[11]. Ginger-partitioned moxibustion is the comprehensive treatment combining pungent-warm and moving nature of ginger with dispelling cold to circulate blood and warm to dredge the meridian of moxibustion. Ginger and moxibustion produce synergies to complement each other. Experiments have confirmed that ginger partitioned moxibustion could significantly improve the general symptoms of experimental spleen deficiency rats, and correct the indiscriminate plasma β-endorphin (β-EP), motilin (MTL)and somatostatin (SS) levels in rats with spleen deficiency, which was better than conventional mild moxibustion[10]. Moxibustion must reach a certain dose to produce the best therapeutic effect. And the moxibustion time is an important factor affecting the dose of moxibustion, therefore, to explore the effect of different dose of moxibustion in ginger-partitioned moxibustion is essential to improve the clinical efficacy.

TFF1 is a class of small molecules secreted by the gastrointestinal tract, and its specific site can be bound by the carbohydrate chain of the mucin to form a stable gel complex and stabilize the gastrointestinal slime layer,thus to play an important role in protection and repair of the gastrointestinal tract[12]. Ren JL, et al[13] pointed out that TFF1 expression was higher in human peptic ulcer and drug-induced rabbit gastric ulcer, suggesting that it plays an important role in gastric mucosal protection and epithelial reconstruction. Li TL, et al[14]found that moxibustion treatment could heal the gastric ulcer caused by spleen deficiency by increase of the TFF1 expression level and repair of the damaged gastric mucosa. MUC5AC is a family of mucin, and secreted by epithelial cells. The main role of MUC5AC is to maintain lubrication of the cavity organs (such as the gastrointestinal tract, respiratory lumen). MUC5AC plays an important role during the repair of the damaged gastrointestinal mucosal barrier, and is also an important biological marker for predicting the development, progression and prognosis of gastric cancer[15]. EGFR has a small amount of expression in normal gastric mucosa epithelial cells, intrinsic membrane cells and mucosal muscle cells. Of which,the distribution is the most in the gastric mucosal epithelial cells, playing a very important role during the repair of gastric mucosal injury. EGFR expression is increased during the gastric mucosal injury[16]. Liu XL,et al[17-18] showed that MUC5AC and EGFR protein expressions were significantly decreased, when the self-defense ability of the gastric mucosal was decreased in rats with spleen deficiency. Bu Zhong Yi Qi decoction can improve the rat spleen syndrome and stimulate the mechanism of gastric mucosal reconstruction, thus to achieve gastric mucosal repair,by increasing the expression of MUC5AC and EGFR proteins.

The results of this study showed that the serum TFF1 and MUC5AC levels, as well as the expression of the EGFR protein in the gastric mucosa of the model group were increased in the successful rat model of spleen deficiency, which indicated that the gastric mucosa had some self-repair function when it was damaged by initiation of cell proliferation. It’s similar to the findings of Li TL, et al[14], while it’s different from that of Liu XL,et al[17-18]. The reason may be related to the duration of intragastric administration of concentrated Da Huang(Radix et Rhizoma Rhei), which was 4 d less in the study conducted by Liu XL, et al[17] than our current study, and may not reach enough stimuli to induce gastric mucosal self-repair function. In addition, this may also be related to the quality of herbs, constitution of the experimental animals, the physical existence of a certain relationship,which are to be further validated in the future experiments. The levels of serum TFF1 and MUC5AC, as well as the EGFR protein in the gastric mucosa were further increased in rats of each group after ginger-partitioned moxibustion at Zusanli (ST 36) and Zhongwan (CV 12), therefore, we inferred that gingerpartitioned moxibustion promoted the proliferation and repair of gastric mucosal injury in rats with spleen deficiency syndrome, by up-regulation of TFF1 expression and binding with the specific mucin MUC5AC, as well as co-activation of EGFR.

At the same time, the results showed that the levels of TFF1 and MUC5AC, as well as the expression of EGFR protein in gastric tissue were higher in the 6 and 9 moxa-cone ginger-partitioned moxibustion groups versus the 3 moxa-cone ginger-partitioned moxibustion group, suggesting that in a certain range, the proliferation and repair of gastric mucosa will be enhanced with the dose increase of moxibustion.However, the effect was similar in 6 and 9 moxa-cone ginger-partitioned moxibustion groups, indicating that it is not that the greater the amount of moxibustion, the stronger the effect.

In summary, ginger-partitioned moxibustion can promote the proliferation and repair of gastric mucosa in rats with spleen deficiency syndrome. The mechanism may be related to the increase of serum TFF1 and MUC5AC levels, as well as activation of EGFR protein expression. Within a certain range, the proliferation and repair of gastric mucosa will be enhanced with the dose increase of moxibustion.
