Study on the Characteristics of Gut Microbiota in Chronic Hepatitis B(CHB)Patients with Damp Heat Syndrome and Liver Depression and Spleen Deficiency Syndrome

Objective:This study was designed to explore the characteristics of gut microbiota in CHB patients with two most common traditional Chinese medicine(TCM)Syndromes—damp heat syndrome and liver depression and spleen deficiency syndrome.Methods:According to the diagnostic criteria of Western medicine,TCM and screening exclusion criteria,65 cases of CHB with damp heat syndrome and 28 cases of CHB with liver depression and spleen deficiency syndrome were finally included in the study.All the basic information was gathered and the fresh fecal samples were collected for 16S rDNA sequencing.16S rDNA of gut microbiota was sequenced using Illumina hiseq 2,500 high-throughput sequencing platform.Based on the optimized sequence,Operational Taxonomic Units(OTU)clustering analysis and taxonomic annotation were carried out.Results:The difference in relative abundance of gut microbiota was significant between damp heat syndrome and liver depression and spleen deficiency syndrome in CHB patients.Cyanobacteria was only found in damp heat syndrome.The relative abundance of Erysipelotrichia and Subdoligranulum were higher in liver depression and spleen deficiency syndrome,while the relative abundance of Rhodospirillales,Alphaproteobacteria and Lachnospira were higher in the damp heat syndrome.LDA Effect Size(LEfSe)analysis showed that Lachnospira,Olsenella and Subdoligranulum had significant difference in species among the two TCM syndromes.Conclusion:The different characteristics of gut microbiota in the two TCM syndromes of CHB patients may play an important role in syndrome formation of TCM,which provides a new field of vision for the accurate diagnosis and treatment of TCM.

Study on the Expression of Organic Anion Transporting Polypeptide (oatp2a1) in Rat with Spleen Deficiency Syndrome and the Exploration of Clinical Significance

Objective: to explore the mechanism of transportation and transformation of dampness by the way of the expression of organic anion transporting polypeptide (oatp) superfamily member 2a1 (oatp2a1) mRNA in rat with spleen deficiency syndrome and the significance in transportation and transformation of dampness. Methods: 32 wistar male rats were divided randomly into four groups: normal group (n = 6), normal + AA group (n = 6), spleen deficiency group (n = 10), Spleen deficiency + AA group (n = 10). After reserpine-induced spleen deficiency model was made, intragastric administration of aristolochic acid (AA) was adopted for three days, the expression of oatp2a1 mRNA were detected in the tissues of lung, liver, kidney, stomach, small intestine and large intestine in four groups by using Fluorescent Quantitative-Polymerase Chain Reaction (FQ-PCR). Results: the expression of oatp2a1 mRNA in above six tissues could be detected. The ex-pression of oatp2a1 mRNA in liver tissue of rat with spleen deficiency syndrome was up-regulated compared to normal group (P = 0.035, P < 0.05), the expression of oatp2a1 mRNA in small intestinal tissue of rat with spleen deficiency syndrome was down-regulated compared to normal group (P = 0.004, P < 0.01), the expression of oatp2a1 in intestinal tissue in normal + AA group is down-regulated compared to normal group (P = 0.032, P < 0.05). Conclusions: oatp2a1 might be one of the material basis involved in transportation and transformation of dampness. The changes of expression of oatp2a1 mRNA in small intestine, liver tissue suggests that small intestine, liver might play an important role in the transportation and transformation of dampness in the state of spleen deficiency. We further concluded that the function of spleen’s governing transportation and transformation of dampness was not only including the function of the gastrointestinal, but also part of the liver function in some degree, which needs to be further studied.

Screening the effective components in treating dampness stagnancy due to spleen deficiency syndrome and elucidating the potential mechanism of Poria water extract

Poria is an important medicine for inducing diuresis to drain dampness from the middle energizer.However,the specific effective components and the potential mechanism of Poria remain largely unknown.To identify the effective components and the mechanism of Poria water extract(PWE)to treat dampness stagnancy due to spleen deficiency syndrome(DSSD),a rat model of DSSD was established through weight-loaded forced swimming,intragastric ice-water stimulation,humid living environment,and alternate-day fasting for 21 days.After 14 days of treatment with PWE,the results indicated that PWE increased fecal moisture percentage,urine output,D-xylose level and weight;amylase,albumin,and total protein levels;and the swimming time of rats with DSSD to different extents.Eleven highly related components were screened out using the spectrum-effect relationship and LC-MS.Mechanistic studies revealed that PWE significantly increased the expression of serum motilin(MTL),gastrin(GAS),ADCY5/6,p-PKAα/β/γcat,and phosphorylated cAMP-response element binding protein in the stomach,and AQP3 expression in the colon.Moreover,it decreased the levels of serum ADH,the expression of AQP3 and AQP4 in the stomach,AQP1 and AQP3 in the duodenum,and AQP4 in the colon.PWE induced diuresis to drain dampness in rats with DSSD.Eleven main effective components were identified in PWE.They exerted therapeutic effect by regulating the AC-cAMP-AQP signaling pathway in the stomach,MTL and GAS levels in the serum,AQP1 and AQP3 expression in the duodenum,and AQP3 and AQP4 expression in the colon.

Clinical research on using acupuncture to treat female adult abdominal obesity with spleen deficiency and exuberant dampness

OBJECTIVE: To observe the curative effect of acupuncture at hour-prescriptive points, a method of midnight-noon ebb-flow, to treat female adult abdominal obesity with spleen deficiency and exuberant dampness.METHODS: Seventy-two patients with adult abdominal obesity with spleen deficiency and exuberant dampness were randomly divided into a treatment group and a control group with 36 patientsin each group. Patients in the treatment group were treated with acupuncture at hour-prescriptive points from 9 to 11 AM every day on the principle of taking points along channels in time. Patients in the control group were treated with acupuncture at any time beyond 9 to 11 AM. Patients in both groups were treated for three courses of treatment.RESULTS: The total effective rate was 87.5% in thetreatment group and 78.8% in the control group.The total curative effect in the treatment group was significantly better than that in the control groupin reducing body weight, body mass index, waistline,obesity level, and clinical symptoms(P<0.05). After treatment, t-test was used on two independent samples to analyze the ratio of waistline to hipline and hipline. A value of 0.01<P<0.05 expressed a weaker outcome and similar curative effect between the two groups in reducing ratio of waistline to hipline and hipline of patients. This value indicates that the treatment group has no obvious superiority to that of the control group for curative effect.CONCLUSION: Because it was superior in reducing waistline and body weight of female adult patients suffering from abdominal obesity with spleen deficiency and exuberant dampness, acupuncture at hour-prescriptive points, a method of midnight-noon ebb-flow, is an effective method to treatobesity.

从脾论治儿童抗生素相关性腹泻

儿童抗生素相关性腹泻(antibiotic-associated diarrhea,AAD)是儿童使用抗菌药后而出现的腹泻,其发病机制与肠道菌群密切相关,抗生素可通过影响肠道菌群的代谢功能及免疫功能导致AAD。中医认为,儿童AAD的病位主要在脾脏,病因不外素体脾胃虚弱、疫毒侵袭、药毒蓄积等,病机以脾虚湿盛、脾气亏虚、脾阳不足为特点。脾虚为小儿AAD发病之本,且脾与肠道菌群具有共通性,故临床治疗小儿AAD可从脾论治。从脾论治儿童ADD以健运脾脏为原则,采用健脾渗湿、健脾益气、健脾温阳等治法,分别以参苓白术散、四君子汤、附子理中丸等为基础方,调理脾脏以达治病求本之目的。
