Introduction:This study aimed to assess the clinical efficacy of Pidan Jianqing decoction in the treatment of type 2 diabetes.Methods:A total of 72 patients with type 2 diabetes differentiated as spleen deficiency with damp-heat syndrome were randomly assigned to a treatment group(n=35)or control group(n=32).Patients in the control group received diet and exercise guidance and medication in the form of 0.5 g metformin hydrochloride tablets,while patients in the treatment group received Pidan Jianqing decoction in addition to the treatment given to the control group.Efficacy was evaluated after 8 weeks of treatment.Results:Efficacy was 91.4%in the treatment group versus 68.8%in the control group,which was a statistically significant difference(P<0.05).Significant group differences were also noted in the number of patients with improvement in symptoms such as dry mouth and polydipsia,frequency of urination and polyuria,abdominal distention and loss of appetite,fatigue and weakness,and sticky stools(all P<0.05),with greater improvement in the treatment group compared to the control group.The fasting blood glucose(FBG)and 2 h postprandial blood glucose levels significantly improved in both groups after treatment(P<0.05);however,there was no significant difference in glycated hemoglobin levels before and after treatment in both groups.Conclusion:Pidan Jianqing decoction can lower blood glucose levels and improve symptoms in patients with type 2 diabetes.

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.

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.

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.

中西医诊治儿童性早熟研究进展

目前,越来越多的无创诊断技术正在运用到儿童性早熟的诊断中,基因检测技术促进了该病遗传病因诊断的发展。对于该病的治疗,西医主要通过病因治疗继发性性早熟,对于特发性外周性性早熟没有特殊治疗方案,目前,中枢性性早熟治疗首选促性腺激素释放激素类似物(gonadotropin-releasing hormone agonist, GnRHa)。中医认为,性早熟病机为阴虚火旺,肝郁化火,痰湿壅滞,治以滋阴降火、疏肝解郁或燥湿化痰,可改善症状,抑制骨龄快速增长。但目前中医药治疗性早熟的临床研究证据等级不高,缺少样本量大、严格且全面的临床研究,未来可通过开展多中心的随机对照、大样本研究以验证中医药治疗性早熟的疗效。网络药理学和中药成分动物实验研究证明了中药治疗性早熟的部分机制,但中药方剂成分复杂,多通过胃肠道吸收后起效,是否可以调节肠道菌群、产生特异性菌群,该菌群是否改变了机体中某些代谢产物水平从而发挥治疗作用尚无相关研究,今后可开展更多的相关机制研究。

特应性皮炎脾虚湿蕴证患者的皮损表现特征分析

目的通过数据挖掘及临床横断面研究结合的方式,探讨特应性皮炎脾虚湿蕴证患者的皮损表现特征。方法现代文献研究方面,检索建库以来至2021年10月31日特应性皮炎脾虚湿蕴证的相关文献,提取并规范皮损特征,对所纳入皮损表现进行频数分析及关联分析;门诊招募于广东省中医院皮肤科就诊的特应性皮炎患者,分为脾虚湿蕴和非脾虚湿蕴2组,填写人口学资料及《特应性皮炎脾虚湿蕴证中医皮损特征采集表》,采用SPSS 27.0软件对数据进行非参数检验和二元Logistic回归分析,比较2组患者的皮损表现差异。结果文献研究共纳入符合要求的文献288篇,其中丘疹、鳞屑、瘙痒、糜烂及渗出等是特应性皮炎脾虚湿蕴证最常见的皮损表现;关联分析提示丘疹、瘙痒、糜烂、渗出、干燥与脾虚湿蕴证的关联性较强。门诊横断面研究共纳入受试者152例,差异分析提示2组患者在粗糙、鳞屑与潮红方面差异有统计学意义(P<0.05),其他皮损表现差异均未见统计学意义(P>0.05);单因素回归结果提示粗糙、鳞屑与潮红会显著影响患者是否为脾虚湿蕴证(P<0.05),而多因素回归结果提示,仅潮红为非脾虚湿蕴证的显著影响因素(P<0.05)。结论特应性皮炎脾虚湿蕴证患者的皮损表现以干燥、鳞屑、肥厚等干性皮损为主,符合亚急性、慢性期皮损表现;临床脾虚湿蕴证患者较少出现渗出、水疱、糜烂等湿性皮损。

基于解痉多肽表达化生病证结合的小鼠模型探讨胃癌前病变脾胃虚实证候的本质

目的为了构建病证结合的小鼠模型及进行胃癌前病变(gastric precancerous lesions,GPL)脾胃虚实证候的本质研究。方法采用他莫昔芬(tamoxifen,TMXFR)诱导构建解痉多肽表达化生(spasmolytic peptide expression metagenesis,SPEM)小鼠模型,并在SPEM模型基础上分别模拟构建脾胃湿热证、脾气虚证模型,结合TMXFR诱导的SPEM模型具有自恢复的特性,以TMXFR组及生理盐水处理组作为对照组,监测小鼠一般情况,HE染色检测SPEM模型的构建及恢复情况,ELISA检测小鼠血清胃泌素水平,PCR检测各组小鼠胃黏膜中miR-7a-5p含量,免疫组化检测各组小鼠胃黏膜中白细胞介素-1β(interleukin-1β,IL-1β)、白细胞介素-13(interleukin-13,IL-13)表达。结果病证结合的脾胃湿热证、脾气虚证组较TMXFR组、SPEM组织恢复明显延迟;脾胃湿热证较对照组及TMXFR组的胃泌素表达异常升高(P<0.05),SPEM模型组小鼠胃黏膜中miR-7a-5p较对照组水平降低(P<0.05),病证结合的脾胃虚实组miR-7a-5p表达较TMXFR有下降趋势;病证结合的脾胃虚实组IL-1β表达较TMXFR组、对照组升高(P<0.05),脾胃湿热证、脾气虚证组中IL-13表达有升高趋。结论此项研究结果侧面证实了在癌前病灶已形成的前提下,虽无幽门螺杆菌感染,在外感湿热之邪、进食肥甘厚腻、饥饱失常、过劳伤脾等诱因下,机体可突破自身代偿修复能力,延缓SPEM恢复甚至使GPL进一步进展。这可能跟miR-7a-5p介导炎症因子IL-1β使得Th1/Th2细胞失衡相关,但具体机制尚待进一步研究。
