Objective To observe the effect of electroacupuncture on corneal Toll-like receptor 4(TLR4)-mediated inflammatory signaling pathway in diabetic dry eye rats and to explore the mechanism of electroacupuncture in the treat-ment of diabetic dry eye.Methods A type 2 diabetic rat model was established in 32 healthy male Sprague-Dawley(SD)rats by intraperitoneal injection of streptozotocin(30 mg·kg-1)for 12 weeks after feeding with high-sugar and high-fat di-et for 4 weeks.Twenty-five successfully modeled diabetic dry eye rats were randomly divided into the model group(non-in-tervention),electroacupuncture group(the"Jingming","Cuanzhu","Sizhukong","Taiyang"and"Tongziliao"acupoints were treated with acupuncture,and then"Cuanzhu"and"Tongzilao"acupoints were treated with electroacupuncture,15 min for each time,once a day),sham acupuncture group(blunt-tip needle pricking was performed at the same acupoints as the electroacupuncture group),and fluorometholone group(1 g·L-1fluorometholone eye drops were used in both eyes at 8 o'clock,13 o'clock,and 18 o'clock,1 drop each time),with 6 rats in each group,lasting for 2 weeks.Another 6 healthy male SD rats were selected as a blank group.Random blood glucose,tear film breakup time(BUT),tear secre-tion,corneal fluorescein staining(FL)score,and corneal touch threshold(CTT)of rats in each group were detected be-fore modeling,after modeling,and after the intervention.Hematoxylin and Eosin(HE)staining was performed to observe the corneal morphologic changes in each group.Immunofluorescence histochemical staining was adopted to detect the cor-neal TLR4-positive expression in each group.The TLR4,phosphorylated nuclear factor-kappa P65(P-NF-KB P65),inter-leukin(IL)-1β,and IL-18 expression levels in the cornea were detected by Western blot.Results After modeling,com-pared with the blank group,BUT,tear secretion and CTT decreased and FL increased in all experimental groups,and the differences were statistically significant(all P＜0.01).After the intervention,compared with the model group,FL de-creased,and BUT,tear secretion and CTT increased in the electroacupuncture group,and the differences were statistically significant(all P＜0.05).Corneal HE staining showed that after the intervention,the corneal surface of rats in the model group and sham acupuncture group was not smooth,and the corneal epithelial cells were thickened and disorganized;the corneal surface of rats in the electroacupuncture group and fluorometholone group was smooth,and the corneal epithelial cells were arranged neatly.After the intervention,compared with the blank group,the corneal TLR4 expression of rats in all other groups was elevated,and the differences were statistically significant(all P＜0.05);compared with the model group,the corneal TLR4 expression of rats in the electroacupuncture group and fluorometholone group was reduced(both P＜0.01).Compared with the blank group,corneal TLR4,P-NF-κBP65,IL-1β and IL-18 protein expressions increased in the model group and sham acupuncture group(all P＜0.05);compared with the model group,these expressions decreased in the electroacupuncture group and the fluorometholone group(all P＜0.05).Conclusion Electroacupuncture can im-prove the ocular surface signs and inhibit the expressions of TLR4,P-NF-κB P65,IL-1 β,and IL-18 in the cornea of type 2 diabetic dry eye rats,and its mechanism of action may be related to the regulation of TLR4-mediated inflammatory signaling pathway,which inhibits ocular surface inflammation in diabetic dry eye rats.

Objective This study aimed to observe the effect of Jiang Tang San Hao Formula(JTSHF)on systemic and intestinal inflammation,as well as on the NLRP3 inflammasome in type 2 diabetic mice(T2DM),and to elucidate its anti-diabetic molecular mechanisms.Methods Four-week-old male C57BL/6 N mice were used to establish the T2DM model using a high-fat diet combined with streptozotocin injection.The diabetic mice were randomly divided into the model,metformin,and JTSHF groups.A control group was also set to provide baseline comparisons.Each group of mice was orally administered with the corresponding medication daily.The metformin group was orally administered with 0.20 g/kg metformin,the JTSHF group was orally administered with 4.26 g/kg JTSHF,and the control group and model group were orally administered with an equal amount of sterile water continuously for 8 weeks.After an 8-week drug intervention via gavage,the lipopolysaccharide(LPS),tumor necrosis factor-alpha(TNF-α),interleukin 1 beta(IL-1β),and interleukin 6(IL-6)serum and colon levels were quantified using an enzyme-linked immunosorbent assay(ELISA).The pathological morphology of the colon was observed using hematoxylin and eosin staining.NOD-like receptor protein 3(NLRP3),apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),caspase-1,zonula occludens-1(ZO-1),occludin,and G-protein coupled receptor 43(GPR43)protein expression in the colon were assessed using immunohistochemistry.The mRNA expression levels of NLRP3,ASC,caspase-1,ZO-1,Occludin,and GPR43 in the colon were detected using Real-time PCR.Results The ELISA data revealed significant differences in inflammatory markers among the groups.Compared with the model group,the JTSHF group exhibited notably reduced LPS,TNF-α,IL-1β,and IL-6 levels(P<0.05).Moreover,compared with the model group,JTSHF treatment upregulated ZO-1,occludin,and GPR43 protein and mRNA expression in the colon and downregulated NLRP3,ASC,and Caspase-1 protein and mRNA expression(P<0.05).Conclusion The inflammatory reaction of T2DM mice is apparent.JTSHF effectively alleviates the systemic and intestinal inflammatory response of T2DM mice by inhibiting the NLRP3 inflammasome and repairing the intestinal mucosal barrier,highlighting the potential molecular mechanisms of the anti-diabetes effects of JTSHF.

Objective:To investigate the effects of Anchang Decoction on intestinal microflora and faecal calprotectin (FC) in rats with severe ulcerative colitis based on probiotics.Methods:Totally 50 rats were taken to prepare a model of severe ulcerative colitis. The rats who successfully modeled were divided into model group, Anchang Decoction low-, medium-, high-dosage groups, Lizhu Changle group, and mesalazine group, with 5 rats in each group. Another 6 rats were set and the blank group. Lizhu Changle group received Lizhu Changle suspension (containing 50 million live bacteria/ml) for gavage; Anchang Decoction low-, medium-, high-dosage groups received Anchang Decoction 1, 5, 10 ml/(kg·d) for gavage; Mesalazine group received Mesalazine suspension (10.5 mg/100 g) for gavage. Rats in the blank group and model group were gavaged with the same volume of normal saline for 7 days. Body mass and disease activity index (DAI) before and after administration were measured. 16s rDNA of lactobacillus and bifidobacterium in feces of rats was detected. FC content of rats was detected by ELISA.Results:Compared with the model group, the weight of rats in each administration group increased ( P<0.05), DAI score decreased ( P<0.05), and the level of calprotectin in feces decreased ( P<0.05), and there was no significant difference in the levels of lactobacillus and bifidobacterium in each administration group ( P>0.05). Conclusion:Anchang Decoction can improve the intestinal micro-ecology by regulating the level of calprotectin in rats with severe ulcerative colitis, thereby playing a therapeutic role.
